Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section.
Order fulfillment generally involves receiving, processing, and shipping orders for goods to purchasers or other recipients. Orders may be business-to-business orders or direct-to-consumer orders, among other possibilities. When an order is received, the goods are retrieved from a point of storage, e.g., a warehouse, for packaging. A container is selected, the goods are placed in the container, and the container is filled with cushioning material to protect the goods during shipment. Common types of cushioning material include air cushions (e.g., seal plastic bags filled with air), bubble wrap, paper cushioning (e.g., crumpled paper), cellulose wadding, and foam packing peanuts.
Conventional approaches to packaging goods for an order are inefficient and often ineffective. In particular, a conventional packaging process typically requires excessive and wasteful amounts of cushioning material. In addition, to provide the desired amount of cushioning, many conventional approaches require large volumes of cushioning material and a larger container, thereby increasing the amount of cost and effort to handle and ship the container. Moreover, even if the space in a container is filled with cushioning material, the cushioning material may not prevent the goods from shifting in the container and becoming damaged during shipment. Indeed, the packaging process itself may result in damaging the goods. For example, filling the remaining space in a container with packing peanuts after goods have been placed in the container may apply forces that may damage the goods.
An automated packaging manufacturing system can produce custom protective structures for positioning and protecting order items in a container according to a custom packaging specification. For example, a packaging optimization module can determine the custom packaging specification after an order is received, so that the custom packaging specification can provide a packaging arrangement based on the actual combination of items in the order. Correspondingly, the automated packaging manufacturing system can produce custom protective structures after the order is received and when the custom packaging specification is ready. To provide prompt shipment of the order, manufacturing of the custom protective structures is preferably completed by the time that the items have been assembled and are ready for packing. In other words, rapid manufacturing of the one or more protective structures occurs while the items are simultaneously retrieved from inventory storage and assembled at a packing location.
To achieve the rapid manufacturing of custom protective structures, the automated packaging manufacturing system can manufacture a protective structure from a plurality of modular elements. The modular elements are readily and rapidly assembled to form a shape that allows items to be packaged according to the custom packaging specification determined from an analysis of the items. Each modular element acts as a single building block for the protective structure. The automated packaging manufacturing system can manipulate each modular element to build a custom shape for the protective structure. Advantageously, because each modular element can be separately manipulated, the amount of material used to form each protective structure can be closely controlled to reduce waste of the material, shipment weight, costs, etc.
The modular elements can adhere to each other to form shapes that can support packaged items during shipment, while also absorbing any shocks, impacts, vibrations, or other external forces that may damage the packaged items. In other words, the adhesion between the modular elements is strong enough, so that the resulting protective structure can maintain the custom shape set forth by the custom packaging specification.

It will be readily understood that certain aspects of the disclosed systems and methods can be arranged and combined in a wide variety of different configurations, all of which are contemplated herein.
I. Overview
Aspects of an order processing system employ an automated packaging manufacturing system for rapid on-demand creation of customized protective structures. These customized protective structures are configured to arrange and protect specific (e.g., unique) combinations of items packed inside a container (e.g., box, crate, etc.). The automated packaging manufacturing system, for example, may be employed by an order processing system in a retail shipping/distribution facility.
When an order is received, the order processing system analyzes the order to identify the items in the order and to determine any number of characteristics about each item, including, but not limited to, shape, size, weight, center of mass, shear strength, bending strength, compression strength, hardness/softness, solid/liquid, material composition, fragility, value, and special handling/packing instructions. Evaluating these characteristics, the order processing system determines a more optimal way to package the items, including, but not limited to: (i) what type of containers to use; (ii) how many of each container type to use; (iii) what items to place in each container; (iv) how the items should be arranged and oriented in each container relative to each other and to the container; and (iv) how a protective structure for each container should be formed to meet the specifications of the arrangement. In addition, the protective structure for each container may be designed in an effort to employ a reduced (and potentially minimal) amount of material and to reduce (and potentially minimize) the volume of the container.
Once the more optimal arrangement of the items in each container is determined, the automated packaging manufacturing system makes one or more custom protective structures for receiving and positioning the items in the container according to the planned arrangement. The protective structures can be formed with specific shapes and sizes according to the planned arrangement. The protective structures may include one or more positioning/retaining features that engage the items and hold them securely in position inside the three-dimensional space of the container. For example, the positioning/retaining features may include recesses and/or cavities that are shaped to receive the items. In addition, the protective structures can be shaped to accommodate the interior shape of the container. In general, the protective structures provide sufficient support so that the items can maintain their positions in the container according to the planned arrangement, while also absorbing any forces that may otherwise damage the items.
According to the present disclosure, the automated packaging manufacturing system assembles a plurality of modular elements to form a protective structure that allows the items to be packaged according to an arrangement determined from the analysis of the order. Each modular element acts as a single building block for the protective structure, and the automated packaging manufacturing system can manipulate each modular element, e.g., via machine/robotic device, to build a custom shape for the protective structure. In one aspect, the modular elements are assembled according to a voxel-based analysis to define the protective structure.
After an order is received, rapid manufacturing of the one or more protective structures may occur while other aspects of the order processing occur simultaneously (e.g., while the items are being retrieved from inventory storage and assembled at a packing location). The one or more protective structures are formed after the order is analyzed to optimize packaging and is ready when the items have been assembled for packing. The dynamic nature of the order processing system allows optimized packaging of different orders, which may include any combination and number of different items. As such, the order processing system can advantageously handle large volumes of mixed-SKU orders.
In one non-limiting example, a first order includes two coffee mugs and a second order includes four glasses. The same order processing system can dynamically determine a unique packaging configuration for each order where, for example, a first protective structure has two internal cavities shaped to receive the two coffee mugs and a second protective structure has four internal cavities shaped to receive the four glasses. Additionally, for example, the system may determine that the glasses are more fragile than the coffee mugs, so the second protective structure may utilize more material to provide extra protection as compared to the first protective structure. Because the order processing system dynamically determines the specifications for the packaging scheme after the order is received, the packaging scheme can be optimized for the particular combination of items that is specified in the order. For example, the packaging scheme can optimize the arrangement (i.e., positioning and orientation) of the items relative to each other.
Order processing systems according to the present disclosure have advantages over other systems that use a generic packing material (e.g., packing peanuts) to fill unused space in the container but fail to keep the items securely in position for an optimal arrangement. Custom protective structures according to the present disclosure can also be optimized to minimize the amount of packaging material used in the container. The disclosed order processing systems also have advantages over systems that use the actual items to shape packaging material. For example, other order processing systems may provide shaped packaging materials by spraying or otherwise applying material (e.g., a foam) directly to the items once they are placed in the container, posing the risk of breaking or damaging the items.
Aspects of the order processing system according to the present disclosure can be partially or wholly implemented under automatic computer/machine control. For example, one or more computers and/or machines (e.g., robotic devices) can be employed to receive an order, determine a more optimal way to package the items, determine optimal configuration(s) for protective structure(s), manufacture the protective structure(s), and pack the items with the protective structure(s) in the container(s).
II. Example System and Method
In some cases, a business may produce some or all of the items in an order. Additionally or alternatively, the business may obtain some or all of the items in an order from another source. In general, the items in an order may include any number and combination of physical objects having different characteristics. With on-demand manufacturing of customized packaging, the order system 100 can provide protective structures for the particular combination of items in an order, regardless of the number of items and the varying characteristics of the items. Moreover, as described further below, the order system 100 determines a customized packaging scheme that can maximize protection for the items while also satisfying other requirements for the packaging.
The order system 100 includes a computing system 101 that manages aspects of the order processing. The computing system 101 includes an order interface 102 through which orders can be received for processing. The order interface 102 may be communicatively coupled to an order entry system (not shown) that receives orders. In some cases, sales personnel may enter orders from customers into the order entry system. Additionally or alternatively, outside customers may enter some or all orders directly into the order entry system. The order entry system, for example, may include order entry screens on a website and/or a software application provided by a business. The order entry screens may be accessible via any personal computing device such as, for example, a mobile phone, a laptop computer, a desktop computer, a tablet computer, etc.
The order system 100 includes various modules that can process the information in the orders received through the order interface 102. In addition, the order system 100 includes various controllers that can control aspects of physical systems that manufacture the customized packaging for each order and that pick, pack, and ship items for each order. Aspects of these modules and controllers can be described with additional reference to the flowchart illustrated in
The order interface 102 can receive an order 02 as shown in
As described in more detail below, to determine a customized packaging scheme for the order 02, the order system 100 considers various characteristics for each item i. An item database 06 stores data for a catalog of items that may be specified in an order 02, and an inventory module 104 maintains the item data in the database 06. The item data includes various characteristics for each item in the catalog. For example, such characteristic data may include, but is not limited to, shape, size, weight, center of mass, shear strength, bending strength, compression strength, hardness/softness, solid/liquid, material composition, fragility, and value of an item. Therefore, according to act 204, the inventory module 104 receives the list 04 of item(s) i specified in the order 02 and can query the database 06 for characteristic data for each item i.
For each item i among the n items, the inventory module 104 determines at decision 206 whether the database 06 stores all desired characteristic data on the particular item i. Characteristic data on the particular item i may be recorded in the database 06 in advance so that the characteristic data is readily available when an order 02 for the particular item i is received. In some cases, at least some of the characteristic data may be determined in advance by administrators of the order system 100. Additionally or alternatively, at least some of the characteristic data may be provided in advance by a manufacturer or supplier of the particular item i. If the database 06 does include all desired characteristic data on the particular item i in advance, the desired characteristic data is readily retrieved from the database 06 according to act 214.
If, however, all desired characteristic data on the particular item i is not available in the database 06, the order system 100 can actively determine unknown characteristics in some embodiments. Specifically, according to acts 208 and 210, the particular item i can be retrieved and examined in an item analysis system 120. The item analysis system 120, for example, may provide an examination station where personnel and/or machines can examine the item i closely and record the characteristic data in the item database 06 or other memory according to act 212. The item analysis system 120 may include various tools for determining the characteristic data. For example, the item analysis system 120 may include measurement tools, such as rulers, scales, scanning devices, imaging devices, etc., for determining the size, shape, weight, etc., of an item.
In one non-limiting example, the item analysis system 120 can be operated by personnel of a manufacturer, retailer, and/or warehouse. In another non-limiting example, the item analysis system 120 can be included in a shipping kiosk (not shown) configured to receive an order 02 from a shipping customer (e.g., a stand-alone kiosk where the customer can drop of an item for on-demand, custom packaging and shipping). In yet another non-limiting example, personnel can additionally or alternatively manually enter qualitative data (e.g., fragility assessment) or non-physical data (e.g., monetary value) through the item analysis system 120.
Because the order system 100 can determine characteristic data dynamically after an order 02 is received, the order system 100 can accommodate orders 02 for items that are custom designed, configured according to particular specifications in the order 02, or otherwise made-to-order. In other words, the order system 100 can take orders 02 for items with characteristic data that can only be determined after the order 02 is placed. For example, the order system 100 can receive orders 02 for one-of-a-kind artwork or jewelry, custom-designed furniture, specially tailored clothing, etc. Once the characteristic data 10 is determined according to the acts 208 and 210, the determined characteristic data 10 is stored in database 06 or other memory in act 212.
Recording the determined characteristic data 10 in the database 06 allows such data to be available for subsequent orders 02, so that acts 208, 210, and 212 do not have to be subsequently repeated. For example, the characteristic data 10 can include identification information (e.g., a barcode, a serial number, a QR code, an image, a text-based description, etc.) that allows the system to identify the characteristic data 10 stored in the database 06 that is associated with items in subsequent orders 02. In this way, the order system 100 can be configured to continuously learn about new items as orders 02 are received.
Although the embodiment of
Once all desired characteristic data 12 for each item i is retrieved according to act 214, a packaging optimization module 105 processes a combination 14 of the characteristic data 12 and determines a custom packaging specification 16 according to act 216. The custom packaging specification 16 produced by act 216 is then passed to an automated packaging manufacturing system 150. Using the custom packaging specification 16, the automated packaging manufacturing system 150 makes one or more protective structures that are employed to position and protect the items i in one or more respective containers for shipping the order 02. As described in detail further below, the custom packaging specification 16 provides a more optimized approach for arranging the items i three-dimensionally in the shipment containers. The protective structures provide sufficient support to keep the items i in position during movement of the shipment containers, while also absorbing any shocks, impacts, vibrations, or other external forces that may damage the items i.
To produce the custom packaging specification 16, the packaging optimization module 105, for example, may analyze the three-dimensional aspects of the protective structures and the containers according to voxel-based approaches. A voxel describes a three-dimensional volumetric pixel, which can be used to break down any geometry according to any desired resolution or scale. Voxel-based approaches strike a balance between practical manufacturing and material optimization, based on the requisite structural properties.
Any number of criteria can be employed to determine the custom packaging specification 16. The packaging optimization module 105 can take the particular characteristic data of each item i into account. In addition, the packaging optimization module 105 can also consider how the particular combination of quantities of the items i can be optimally packaged. For the combination, the packaging optimization module 105 may determine: (i) what type of containers to use; (ii) how many of each container type to use; (iii) what items to place in each container; and (iv) how the items should be arranged and oriented in each container relative to each other and to the container. Furthermore, the packaging optimization module 105 may consider other aspects of the order 02. For example, the custom packaging specification 16 may take shipment specifications, e.g., distance of shipment, location of recipient, type of shipping vessel (e.g., ground, air, water), environmental conditions during shipment, etc., into account.
A more optimal packaging scheme, for example, may among other considerations:
Because the custom packaging specification 16 is determined after the order 02 is received, the custom packaging specification 16 can be dynamically customized to account for aspects that may not be known until after the order 02 is placed. For example, the inventory module 104 may determine that a quantity of an item in the order 02 is not in stock, e.g., in the inventory storage 110. As such, the unavailable item may be shipped separately from the rest of the order 02. Responding dynamically to changing inventory levels, the packaging optimization module 105 determines a custom packaging specification 16 that only has to accommodate items that are actually available and that can be included in the present shipment. Designing the packaging before the order 02 is placed (or before available inventory is determined) might otherwise result in manufacturing packaging for items that are not even available for shipment.
While the automated packaging manufacturing system 150 makes the protective structure(s) according to the custom packaging specification 16, an automated picking system 130 acts in parallel to retrieve the items i from inventory storage 110, according to act 222. The computing system 101 includes a picking/packing controller 106 that controls aspects of the automated picking system 130. To enhance efficiency, rapid manufacturing allows the protective structure(s) to be completed or substantially completed during the time generally required to complete the picking process. As such, the protective structure(s) are available (with no delay or with minimal delay) when the items i are ready for packing.
Once the items i have been retrieved, the picking/packing controller 106 causes an automated packing system 140 to pack the items i in the container(s) with the protective structure(s) according to act 224. In particular, the custom packaging specification 16 is employed to direct the automated packing system 140 how each item i should be packed in the custom protective structure(s). If the custom packaging specification 16 designates that the items i are to be shipped in more than one container, the automated packing system 140 packs each subset of items i with its designated protective structure(s) in its designated container. The automated packing system 140 ensures that the subset of items i are properly combined with the protective structure(s) so that they are arranged in the three-dimensional space of the container according to the optimized packaging scheme. In some cases, the automated packing system 140 can move with one or more degrees-of-freedom to manipulate each item i so that the item i is properly placed in the protective structure(s) and/or properly oriented relative to the container and other items i.
The automated picking system 130 and the automated packing system 140 allow some or all aspects of the picking process of act 222 and the packing process of act 224 to be generally achieved without manual input or human intervention. For example, the automated picking system 130 and the automated packing system 140 may employ the picking/packing controller 106 and the packaging manufacturing controller 107, respectively, to control machines, robotic devices, conveying devices, etc., to physically move and manipulate the items i, the protective structures, the containers. and related objects.
Once the automated packing system 140 assembles the items i with the respective protective structures and containers, the containers are prepared for shipment by a shipping system 160. The shipping process can be handled by a shipping module 108 in the computing system 101. For example, the shipping module 108 can prepare shipping documents, schedule delivery of the packaged items i, track delivery, etc. In one example implementation, the shipping module 108 can interface with a package delivery service such as GOOGLE EXPRESS to facilitate same-day delivery of the assembled package to the recipient and/or delivery during the recipient's preferred delivery time window.
As described, the order system 100 illustrated in
III. Packaging Determination & Optimization
As described above, after all of the characteristic data 14 is retrieved, the packaging optimization module 105 determines a custom packaging specification 16 for creating an on-demand, order-specific packaging of the one or more items i at act 216. The packaging specification 16 can be characterized by, for example, one or more container parameters relating to a container in which the item(s) i will be packaged, one or more arrangement parameters relating to an arrangement for positioning the item(s) i within a three-dimensional space of the container, and one or more protection parameters relating to a protective structure for protectively retaining the item(s) i in the container according to the arrangement.
The container parameter(s) indicate which of a plurality of potential containers is to be utilized by the automated packing system 140 for packing the one or more items i. The potential containers can have, for example, different materials, volumes, dimensions, shapes, and/or sealing mechanisms (e.g., tape, slots and tabs, adhesive, etc.). Additionally or alternatively, for example, the potential containers can have a variety of different construction types (e.g., single face, single-wall, double-wall, etc.), material thicknesses (e.g., flute sizes), and/or performance characteristics (e.g., burst strengths, edge crush strengths, stacking strengths, compression strengths, flat crush characteristics, water resistances, electromagnetic insulation characteristics, temperature insulation characteristics, surface treatments, coatings, etc.). Accordingly, the container parameters can indicate, for example, a type of container (e.g., a material, a thickness, a shape, a volume, dimensions, a sealing mechanism, a construction type, performance characteristics, etc.) and a quantity of containers for packaging the one or more items i according to the packaging specification 16.
Non-limiting examples of materials that can be utilized for the containers include paperboard, plastic, corrugated fiberboard (i.e., cardboard), wood, metal, combinations thereof, and/or the like. According to some aspects, the potential containers can include various different standard-sized boxes that are commonly used for shipping such as, for example, cuboid shaped boxes. According to additional and/or alternative aspects, the plurality of potential containers can include containers having non-standard sizes and shapes such as, for example, irregularly shaped containers (e.g., cylindrical, heart-shaped, triangular pyramid, cone, etc.) or asymmetrically shaped containers. Additionally, for example, one or more of the plurality of potential containers can be configured to contain the item(s) i in a wrap-like manner (e.g., a stretch wrap or a shrink wrap). In general, the container(s) provide a three-dimensional space in which the one or more items i can be held and transported.
The arrangement parameters indicate an arrangement, which is a positioning for each of the one or more items i within the three-dimensional space defined by the container(s) (i.e., an interior space of the container(s)). If, for example, the quantity of containers is greater than one, the arrangement parameters can further include an indication as to which of the one or more items i will be placed in which of the containers.
According to some aspects of the present disclosure, a coordinate system (e.g., a Cartesian coordinate system) can be employed to provide a frame of reference for indicating the relative positions (i.e., locations and/or orientations) of the one or more items i with respect to each other and the interior space of the container.
As further shown in
According to some aspects of the present disclosure, the coordinate system 372 can also be used to spatially map the characteristic data 14 of the items i to the interior space 364 of the container 370. For example, a three-dimensional data model can be determined for each item i based on the characteristic data 14 relating to the size, shape and/or dimensions. Using a computer-based simulation, the packaging optimization module 105 can spatially map the data model to the coordinate system 372 to determine the portion of the interior space 364 that is to be occupied by the item i when positioned in the container 370 according to the arrangement 376.
According to additional and/or alternative examples, other characteristic data 14 associated with the one or more items i can be mapped to the interior space 364 and the coordinate system 372. For example, the characteristic data 14 (or data models based thereon) relating to a value, a weight, a center of mass, a shear strength, bending strength, compression strength, a hardness/softness (e.g., a durometer value), a state of matter (e.g., solid, liquid, gas), a material composition, a fragility, information about nesting areas into which other items i may be nested, and other properties can be spatially mapped to the interior space 374 of the container 370 by the packaging optimization module 105. As will be described further below, such spatial mapping of the characteristic data 14 can be employed to improve or optimize the packaging specification 16 based on one or more enhancement criteria.
While the example illustrated in
Although a single coordinate point is indicated for each item i in
The protection parameters indicate information related to the design and manufacture of a protective structure for protecting the one or more items i when positioned within the container 370 according to the arrangement 376. For example, the protective structure can provide both support to retain the items i in the positioning of the arrangement 376 and cushioning to protect the items i during shipment. The protection parameters are communicated to the automated packaging manufacturing system 150, which is configured to manufacture the custom-designed protective structure based on the protection parameters. In other words, the protection parameters enable the protective structure to be produced on-demand and in a customized manner in response to an analysis of the characteristic data 14 associated with the ordered items i. This is in contrast to other systems that select one standard protective structure from a plurality of predefined, standard protective structures (e.g., conventional bubble wrap, air pillows, packing peanuts, loose fill, etc.) based on a mere identification of an item i. The dynamic nature of the protective structures provides for improved or optimized packaging of different orders 02, which may include any combination and number of different items i.
Because the protective structures may be highly customized, the protection parameters can be configured to indicate information that facilitates the manufacture of a vast number of different, potential configurations for the protective structure. For example, the protection parameters can indicate a material composition, a material density, a size, a shape, and/or dimensions of a protective structure that can be manufactured by the automated packaging manufacturing system 150. Non-limiting examples of materials include polymeric foam (e.g., polystyrene, polypropylene, polyethylene, polyurethane, etc.), plastic, pulp, cardboard, compostable materials (e.g., starch-based materials, mushroom-based materials, etc.), bioplastics, fibrous materials, woven materials, other cushioning materials, etc. According to some aspects, the protective structure can be made from a single material. According to alternative aspects, the protective structure can be made from a plurality of materials. For example, the protective structure can be configured to be compliant in one or more select areas and rigid in other areas by forming the protective structure from different materials.
The protective structure 378 can have a symmetric or an asymmetric shape. According to some aspects, an exterior shape of the protective structure 378 can generally correspond to an internal shape of the container 370. For example, an example protective structure 378 can have an exterior shape that is generally in the shape of a cube, which corresponds to a cube-shaped interior space 374 of an example container 370. According to other aspects, the exterior shape of the protective structure 378 can be different from the internal shape of the container 370. For example, the protective structure 378 can include a plurality of legs that each extend from a main body to a corner of a cuboid container 370. In some instances, the protective structure 378 can be configured to closely fit within the interior space 374 of the container 370 to mitigate impacts due to undesirable movement of the protective structure 378 relative to the container 370.
During shipping, the package may be subject to a number of impacts, vibrations, or other external forces that may potentially damage the one or more items i. To protectively retain the items i in the arrangement 376, the protective structure 378 includes one or more recesses and/or cavities 380 configured to receive the one or more items i according to the arrangement 376 (as shown, e.g., in
According to some aspects, the one or more recesses and/or cavities 380 are located within an interior of the protective structure 378. That is, the protective structure 378 can at least partially or fully enclose the one or more items i within the protective structure 378 on all sides of the one or more items i. In this way, the protective structure 378 can protect the one or more items i from shocks, vibrations, temperature, humidity, dust, insects, liquids, electrostatic shock, etc., in all six dimensions while at the same time retain the one or more items i in the desired arrangement 376.
It is contemplated that, according to other aspects, the protective structure 378 can additionally include one or more recesses externally located on the protective structure 378. That is, the externally located recesses can be configured so that an item i is not enclosed on all sides. For example, in some instances, an item i might not need to be protected by the protective structure 378 to the same extent as other items i. In such instances, the items i requiring less protection may be located externally on the protective structure 378 while the items i requiring greater protection may be located internally within the protective structure 378. As one non-limiting example, a protective structure 378 for packaging a porcelain figurine and a down coat can include an internal cavity 380 for fully enclosing the porcelain figurine within the protective structure 378 and an external recess for receiving the down coat on an exterior surface of the protective structure 378.
It is further contemplated that, according to additional or alternative aspects, the protective structure 378 can include features other than the recesses and/or cavities 380 for protectively retaining the items i. As non-limiting examples, the protective structure 378 can include one or more clips, rings, areas of increased material density, slots, interlocking geometries, etc for protectively retaining the items i. It is also contemplated that, according to additional or alternative aspects, the protective structure can have an exterior that is configured to withstand the rigors of shipment such that the items i can be transported in the protective structure 378 without a container 370.
In the example illustrated in
According to some aspects, the protective structure 378 can be a unitary structure. For example, the protective structure 378 can be configured as a clamshell-type structure that can be hingedly opened and closed to facilitate insertion and removal of the one or more items i from the one or more recesses and/or cavities 380. According to additional and/or alternative aspects, the protective structure 378 can be a multiple-part construction. For example, the protective structure 378 can include a plurality of separate pieces that can be stacked on top of one another or otherwise engaged to partially or fully enclose the one or more items i within the protective structure 378. In general, the protective structure 378 can have at least two portions that are couplable to form the protective structure 378 and facilitate insertion/removal of at least one of the one or more items i to/from an enclosed position within the protective structure 378.
According to some aspects of the present disclosure, the protective structure 378 can be spatially mapped to the interior space 374 of the container(s) 370 using the coordinate system 372 and/or voxel-based data described above. For example, the size, shape, and/or dimensions of the protective structure 378 can be mapped to the interior space 374 and the coordinate system 372 (e.g., via a data model of the protective structure 378). The coordinates and/or voxel-based data associated with the protective structure 378 can thus indicate the portions of the interior space 374 that will be occupied by the protective structure 378 when the protective structure 378 is positioned in the container 370.
According to some example implementations, the coordinate information and/or the voxel-based data associated with protective structure 378 can be included in the protection parameters and communicated to the automated packaging manufacturing system 150 to facilitate the manufacture of the protective structure 378. Additionally, for example, the coordinate information and/or the voxel-based data associated with the protective structure 378 and the arrangement 376 can be utilized by the packaging optimization module 105 to ensure that the one or more recesses and/or cavities 380 are consistent with the arrangement 376 of the one or more items i and vice versa (as shown, e.g., by
In addition to spatially mapping the size, shape, and/or dimensions of the protective structure 378, the coordinate system 372 can be employed to spatially map one or more protection characteristics of the protective structure 378 to the interior space 374 of the container 370. The one or more protection characteristics can include, for example, metrics for quantifying and/or characterizing an amount of protection provided by the protective structure 378 against shocks, vibrations, thermal effects, humidity effects, air pressure effects, dust, insects, liquids, static electricity, combinations thereof, and/or the like. The one or more protection characteristics can additionally or alternatively relate to, for example, an amount of resiliency (i.e., an capability to withstand multiple impacts) and/or an amount of resistance to creep (i.e., deformation under a static load) of the protective structure 378. Still further, the one or more protection characteristics can relate to other factors that may affect the processes for determining and/or evaluating a protective structure 378 such as, for example, a material cost, an environmental impact of the material, whether a material is out of stock, an amount of energy required to produce the protective structure, etc. By spatially mapping the one or more protection characteristics, informed decisions can be made as to the design and implementation of a protective structure 378 customized for a specific order 02 of the one or more items i.
As described above, the custom packaging specification 16 is determined based on the characteristic data 14 of the one or more items i. For example, the custom packaging specification 16 can include a protective structure 378 having recesses and/or cavities 380 that correspond to the shapes and sizes of the one or more items i indicated by the associated characteristic data 14. According to additional aspects of the present disclosure, the custom packaging specification 16 can be further determined by the packaging optimization module 105 by processing the characteristic data 14 using one or more design criteria that provide a framework for achieving desired packaging objectives. For example, the design criteria can include one or more enhancement criteria and/or one or more design constraints described further below. Additionally, for example, the one or more design criteria can define a set of relationships (e.g., if-then rules) between the characteristic data 14, the enhancement criteria, and/or the design constraint(s) (e.g., if the characteristic data 14 for an item i indicates that the item i is worth more than X dollars, then the packaging specification 16 is designed to protect the item i from an impact of at least Y force).
The enhancement criteria can be employed by the packaging optimization module 105 to custom design a more optimal custom packaging specification 16 for the specific collection of items i in the order 02. Non-limiting examples of enhancement criteria include packaging efficiency criteria, cost criteria, protection criteria, package handling criteria, and/or aesthetics criteria.
The packaging efficiency criteria can relate to an amount of material required to implement a custom packaging specification 16 (i.e., an amount of material for forming the container 370 and/or an amount of material for forming the protective structure 378). The packaging efficiency criteria can be thus utilized to reduce or minimize the amount of material required to package the one or more items i, which may reduce the costs and the environmental impact associated with packaging and shipping the one or more items i.
The cost criteria can relate to a cost associated with a custom packaging specification 16. For example, the cost criteria can be based on a cost of materials for the container(s) 370, a cost of materials for the protective structure(s) 378, one or more freight rates for shipping the assembled package (e.g., based on a size and/or a weight of the assembled packages), and/or an amount of time or resources (e.g., labor or machinery) required to assemble the package according to a particular custom packaging specification 16. The cost criteria can be thus utilized to reduce or minimize the cost associated with packaging and shipping the one or more items i.
The protection criteria can relate to an amount or a type of protection that is provided for each of the one or more items i due to the container(s) 370, the protective structure(s) 378, and/or the arrangement 376. For example, the protection criteria can relate to the protection provided by the custom packaging specification 16 for shocks, vibrations, thermal effects, humidity effects, air pressure effects, dust, insects, liquids, static electricity, combinations thereof, and/or the like. The protection criteria can additionally or alternatively relate to, for example, an amount of resiliency (i.e., a capability to withstand multiple impacts), an amount of resistance to creep (i.e., deformation under a static load), a burst strength, an edge crush strength, a stacking strength, a compression strength, flat crush characteristics, etc. The protection criteria can be thus utilized to improve or maximize the protection provided to the items i during shipping. In some embodiments, aspects of the protection criteria (as well as other criteria) can be determined from feedback received from past recipients. For example, past recipients may provide feedback regarding items that were damaged during shipment. Using this feedback, the protection criteria can be improved to provide more effective protection for the items. For example, it may be determined that certain items require more cushioning or need to be arranged away from the sides of the container in order to reduce damaging shocks during shipment.
The package handling criteria can relate to a distribution of weight and other stability aspects of the custom packaging specification 16. If the weight within the container 370 is too unevenly distributed (e.g., top heavy or side heavy), a package may be difficult to handle and more likely to be dropped. By more evenly distributing the weight of the one or more items i and/or the protective structure 378, the risk of damage may be reduced or mitigated. According to one non-limiting example, the package handling criteria can relate to a distance between a center of gravity of a package assembled according to the package specification and a target center of gravity location of the container 370 (e.g., a center point of the interior space of the container 370 or a center area within the container 370). The closer (i.e., more aligned) the center of gravity of the custom packaging specification 16 is to the target center of gravity location, the greater the balance and stability of the custom packaging specification 16.
The aesthetics criteria can relate to the aesthetics of a custom packaging specification 16. For example, the aesthetics criteria can relate to a positioning or distribution of the one or more items i in the custom packaging specification 16. In an example implementation, a custom packaging specification 16 may be considered more aesthetically pleasing if a greater number of the one or more items i are immediately viewable when the protective structure 378 is opened. In another example implementation, a custom packaging specification 16 may be considered more aesthetically pleasing if preferred portions of the one or more items i (e.g., a portion including a graphic or label) are immediately viewable when the protective structure 378 is opened. In still another example implementation, a custom packaging specification 16 may be considered more aesthetically pleasing if the positioning of the one or more items i conveys a sense of symmetry, proportionality, and/or order to a recipient. According to additional and/or alternative examples, the aesthetic criteria can include an indication as to whether certain types of protective structures 378 and/or containers 370 are considered to be more aesthetically pleasing than other types of protective structures 378 based on, for example, a material, a shape, a size, a color, and/or a coating on the protective structure 378 and/or the container 370. For example, due to the level of customization that may be achieved by the system 100, uniquely shaped protective structures 378 may have artistic value.
According to some aspects of the present disclosure, the packaging optimization module 105 can be configured to first determine a plurality of alternative packaging specifications 16 based on the characteristic data 14 of the one or more items i and then select one of the alternative packaging specifications 16 based on the one or more enhancement criteria. The plurality of alternative packaging specifications 16 can be determined using one or more algorithms configured to design a custom packaging specification 16 based on part or all of the available characteristic data 14 for the one or more items i. As one non-limiting example, the one or more algorithms can include a nesting algorithm and/or a volumetric optimization algorithm, which can minimize airspace in the container 370, thereby reducing the volume of the assembled package and saving space on trucks.
Additionally, for example, the design algorithms can determine the alternative packaging specifications 16 based on a set of design constraints (e.g., minimum requirements, preferences, etc.). The design constraints can be determined based on the analysis of the characteristic data 14 and can relate to any aspect of the container 370, the arrangement 376, and/or the protective structure 378 described above (e.g., material, shape, size, dimensions, performance characteristics, protection characteristics, number of containers 370, number of protective structures 378, etc.). As one non-limiting example, a design constraint can indicate that the custom packaging specifications 16 should be capable of withstanding an impact of at least a threshold g-force without damage to the items i. As another non-limiting example, a design constraint can indicate that a package assembled according to a custom packaging specification 16 cannot exceed a maximum threshold weight or a maximum threshold size. Additionally, for example, the design constraint can be based on information indicated in the order 02. For example, the order 02 can indicate that a particular shipper, a particular size container, a particular type of packaging material, etc. be used.
In some example implementations, the number of alternative packaging specifications 16 that are designed and evaluated by the packing optimization module 105 can be based on an estimated time required to retrieve the items i by the automated picking system 130. For example, the packaging optimization module 105 can be communicatively coupled to the order processing module 103 and/or the inventory module 104 to receive information about the estimated to time for retrieving the items i. Accordingly, the packaging optimization module 105 can ensure that the custom packaging specification 16 is ready by the time the items i arrive for packing (or at least minimize delays).
According to some aspects, the custom packaging specification 16 that is utilized by the automated packaging manufacturing system 150 and the automated packing system 140 can be selected from the plurality of alternative packaging specifications 16 based on a single enhancement criterion. As one non-limiting example, the characteristic data 14 of the one or more items i can be processed to determine a custom packaging specification 16 that is configured to utilize the least amount of material for the protective structure 378 regardless of any other enhancement criteria. As another non-limiting example, the characteristic data 14 of the one or more items i can be processed to determine a custom packaging specification 16 that will cost the least amount to produce and ship to a destination indicated in the transaction details of an order 02.
According to other aspects of the present disclosure, the packaging optimization module 105 can be configured to determine a custom packaging specification 16 for the one or more items i based on a plurality of the enhancement criteria. In many implementations, there may not be one custom packaging specification 16 that can be considered the best for all of the enhancement criteria. Rather, it may be that there are tradeoffs associated with the enhancement criteria. For example, a custom packaging specification 16 that costs the least may not provide the most protection for the one or more items i. As another example, an arrangement 376 that is the most aesthetically pleasing may unevenly distribute the weight of the one or more items i such that the container 370 is difficult to handle.
To select one of the plurality of alternative packaging specifications 16 based on a plurality of enhancement criteria, the packaging optimization module 105 can be configured to employ one or more multiple-criteria decision analysis (MCDA) algorithms. Non-limiting examples of the one or more multiple-criteria decision analysis algorithms can include an aggregated indices randomization method (AIRM), an analytic hierarchy process (AHP), an analytic network process (ANP), a data envelopment analysis, a decision expert (DEX), a dominance-based rough set approach (DRSA), an elimination and choice expressing reality (ELECTRE) analysis, an evidential reasoning approach (ER), a goal programming application, a multi-attribute global inference of quality (MAGIQ) analysis, a multi-attribute utility theory (MAUT), a multi-attribute value theory (MAVT), a potentially all pairwise rankings of all possible alternatives (PAPRIKA) analysis, a technique for the order of prioritization by similarity to ideal solution (TOPSIS) analysis, a value analysis (VA), a weighted product model (WPM), a weighted sum model (WSM), combinations thereof, and/or the like.
Referring now to
According to some aspects of the present disclosure, the packaging optimization module 105 can simulate how each alternative packaging specification 16 would perform under various test conditions to can evaluate the potential alternative packaging specifications 16. For example, the packaging optimization module 105 can employ physics-engine software for simulating drops from various heights, compressions under various loads, vibrations, thermal effects, etc. According to additional or alternative aspects of the present disclosure, the packaging optimization module 105 can utilize the spatial mapping of the data models for the items i, the protective structure, and the container 370 to run the simulations and identify where potential points of failure or weakness may be located. It is contemplated that, according to some aspects of the present disclosure, the packaging optimization module 105 can be configured to determine an initial set of alternative packaging specifications 16, analyze the initial set based on the simulations, and then modify one or more of the alternative packaging specifications 16 based on an outcome of the simulations. In some instances, the simulation, analysis, and modification process may be iteratively repeated until no further improvements are achieved.
It is further contemplated that, according to some embodiments, the order system 100 can include one or more user input/output devices (not shown) for facilitating user review and modifications to one or more of the alternative packaging specifications 16. For example, a display device can be configured to display information related to the packaging specifications 16 in the form of text, numbers, and/or graphics (e.g., information related to materials, shapes, sizes, dimensions, performance characteristics, protection characteristics, number of containers 370, number of protective structures 378, simulation data, spatial mapping graphics, etc.). Additionally, for example, a keyboard, a mouse, and/or a touch screen can be configured to allow a user to modify aspects of the packaging specification 16 to further customize the packaging specification 16.
According to some aspects of the present disclosure, the container parameters, the arrangement parameters, and the protection parameters can be interdependently determined together. According to some alternative aspects of the present disclosure, one or more of the container parameters, the arrangement parameters, and the protection parameters can be determined independently of the others. As one non-limiting example, to minimize the overall size of an assembled package, the arrangement 376 can be determined first, then the protective structure 378 can be determined based on the arrangement 376, and then the container 370 can be determined based on the protective structure 378.
To illustrate some example features of a custom packaging specification 16 that may be determined based on the characteristic data 14 and the enhancement criteria,
In the example packaging specification 16 of
In the example packaging specification 16 of
In the example packaging specification 16 of
Other potential features of a custom packaging specification 16 that can be determined based on the enhancement criteria include, for example, providing additional material for the protective structure 378 in select areas to improve the protection characteristics of the protective structure 378 for a fragile item i or a valuable item i. Additionally, for example, the custom packaging specification 16 can be configured to include less material for the protective structure 378 or an aperture in the protective structure 378 adjacent to items i that are less fragile or valuable. As yet another example, the custom packaging specification 16 can be configured to include a plurality of containers 370 to reduce shipping costs due to the weight and the size of the assembled containers 370. As still another example, the custom packaging specification 16 can be configured to separate items I into different containers 370 based on regulatory requirements mandating that certain items i be shipped individually or under particular circumstances that may not be necessary or desirable for other items i. As yet another example, the custom packaging specification 16 can be configured to have varying densities of materials for the protective structure 378 to vary the protection characteristics for different items i (e.g., areas with denser material may provide more protection than less areas with less dense material). In another example, the custom packaging specification 16 can be configured such that a center of gravity of the protective structure 378 is designed to counter an imbalance due to a center of gravity of the arrangement 376 of items i and vice versa. In a further example, the custom packaging specification 16 can be configured to nest a plurality of items i to reduce the amount of material, the volume of the container 370, the empty air space in the container 370, and the costs. In yet another example, the custom packaging specification 16 can be configured to minimize the number of separate pieces that comprise the protective structure 378. In still another example, the custom packaging specification 16 can be optimized to reduce an associated environmental impact due to, for example, an amount of energy required to manufacture the protective structure 378 and/or pack the items i, an amount of waste associated with the manufacture of the protective structure 378, and/or the types of materials utilized in the packaging specification 16. In another example, the packaging specification 16 can be optimized to make it easy for a recipient to unpack the items i from the container 370. It should be understood that the features for a custom packaging specification 16 described and illustrated for
After the custom packaging specification 16 is determined at act 216, the protection parameters are communicated from the packaging optimization module 105 to the packaging manufacture controller 107. At act 218, the protective structure 378 is manufactured by the automated packaging manufacturing system 150, controlled by the packaging manufacture controller 107, according to the protective parameters of the custom packaging specification 16. The automated packaging manufacturing system 150 is configured to rapidly manufacture the protective structure 378. Rapid manufacturing allows the protective structure 378 to be completed or substantially completed during the time generally required to complete the picking process described further below.
According to some aspects, the protective structure 378 can be formed using an additive manufacturing process. For example, the protective structure 378 can be formed by a 3D printing process, which forms the protective structure 378 by laying down a plurality of successive layers of material. According to some additional or alternative aspects, the protective structure 378 can be formed using a subtractive manufacturing process. For example, a cutting process, a milling process, a drilling process, and/or an ablation process can be employed to remove controlled amounts from a raw material to form the protective structure 378. According to further additional or alternative aspects, the protective structure 378 can be formed by a stamping process, a casting process, a molding process, a forming process, a machining process, and/or a joining process. In general, however, the protective structure 378 can be formed by reshaping a packaging material. Depending on the manufacturing process or the materials employed, the forming of the protective structure 378 can also include a curing process.
According to some aspects of the present disclosure, the protective structure 378 can be manufactured based on the coordinate information and/or voxel-based data for the protective structure 378 indicated by the protection parameters. For example, the automated packaging manufacturing system 150 also can employ a coordinate system 372 that provides a frame of reference for a work space upon which the protective structure 378 is manufactured such that the coordinate information and/or voxel-based data of the protective structure 378 can be mapped to the coordinate system 372 of the automated packaging manufacturing system 150.
IV. Picking Process
As described above, the automated picking system 130 shown in
As shown in
When the order 02 is received by the order system 100, the picking/packing controller 106 of the computing system 101 causes the automated picking system 130 to retrieve the desired quantities of items i=1, 2, . . . , n from their respective receptacles 112i. In the example of
The automated picking system 130 provides a dispensing device 132i for each receptacle 112i. Each dispensing device 132i moves the desired quantity of item i from the receptacle 112i to a respective bin 134i. The bins 134 move on a conveying device 136 that passes near the receptacles 112. For each item i, the automated picking system 130 operates the conveying device 136 to position the bin 134i near the receptacle 112i and then operates the dispensing device 132i to move the specified quantity of item i into the bin 134i on the conveying device 136.
Each dispensing device 132i may be individually controlled by the automated picking system 130. For example, each dispensing device 132i may include an electromechanically and/or hydraulically actuated mechanism that pushes the desired quantity of item i into the bin 134i from the receptacle 112i. The items i may be arranged in the receptacle 112i to allow the mechanism to push one item i at a time from the receptacle 112i. Furthermore, a surface, e.g., an inclined surface defined by a series of rollers, may lead from the receptacle 112i to the bin 134i to facilitate the transfer of the item i.
The automatic picking system 130 assigns each bin 134i to the respective items i, i.e., bin 134i=1 is assigned to item i=1, bin 134i=2 is assigned to item i=2, . . . , bin 134i=n is assigned to item i=n. Knowing these bin assignments, the automatic picking system 130 can determine where the retrieved items i=1, 2, . . . , n are by tracking the locations of bin 134i=1, bin 134i=2, . . . , bin 134i=n, respectively. Accordingly, each bin 134i includes an identifier 135i that allows the automated picking system 130 to track the location of the bini. For example, the identifier 135i may include a barcode and/or other marking that can be read by image capture and/or scanning devices at various locations. Additionally or alternatively, the identifier 135i may include a radio-frequency identification (RFID) or other signal-emitting device that can be used to track the bin 134i wirelessly.
After the items i=1, 2, . . . , n have been transferred from the receptacles 112i to the bins 134i, respectively, the automated picking system 130 operates the conveying system 136 to move the bins 134 to a designated location for packing by the automated packing system 140. During the picking process, the automated picking system 130 may also retrieve items for other orders. The bins 134 for the order 02 may then become interspersed with bins for other orders. As such, the automated picking system 130 tracks the location of the bins 134 with the items i=1, 2, . . . , n so that they are conveyed on the conveying device 136 in the proper direction and deliver the items i=1, 2, . . . , n to the appropriate location for packing.
This picking process occurs in parallel with the process of determining and manufacturing the protective structure(s) 378 described above. Rapid manufacturing allows the protective structure(s) 378 to be completed or substantially completed during the time generally required to complete the picking process. As such, the protective structure(s) 378 are available (with no delay or with minimal delay) when the items i=1, 2, . . . , n are ready for packing. The proper protective structure(s) 378 are also conveyed to the appropriate location to be assembled with the retrieved items i=1, 2, . . . , n for packing.

Although each receptacle 112 shown in
V. Packing Process
As described above, when the items i=1, 2, . . . , n have been retrieved and delivered to a designated packing location, the picking/packing controller 106 causes the automated packing system 140 to pack the items i in one or more containers 370. In particular, the automated packing system 140 packs the items i with one or more custom protective structures 378 according to the custom packaging specification 16. Referring to
As shown in
As described above, the bins 134a and 134b include identifiers 135a and 135b that allow the automated picking system 130 to track the location of the bins 134a and 134b and the items ix and iy, respectively. The identifiers 135a and 135b may include a barcode and/or other marking that can be read by image capture and/or scanning devices at various locations. Additionally or alternatively, the identifiers 135a and 135b may include a radio-frequency identification (RFID) or other signal-emitting device that can be tracked wirelessly. When the bins 134a and 134b arrive at the packing location 141, the identifiers 135a and 135b also allow the automatic packing system 140 to confirm that the items ix and iy specified in the order 02 have been delivered to the packing location 141.
As shown in
Another conveying device 336 (e.g., a conveyor belt) delivers the protective structures 378a and 378b from the automated packaging manufacturing system 150 to the packing location 141. The automated packing system 140 packs the items ix and iy for shipment with the protective structures 378a and 378b. The protective structures 378a and 378b are manufactured to provide a more optimal packaging scheme as set forth by the custom packaging specification 16. In particular, the automated packaging system 150 manufactures the first protective structure 378a to define recesses 380a and 380b. Correspondingly, the automated packaging system 150 manufactures the second protective structure 378b to define recesses 380a′ and 380b′. When the protective structures 378a and 378b are combined, the recesses 380a and 380a′ define an internal cavity that receives the item ix, and the recesses 380b and 380b′ define two internal cavities that respectively receive the items iy. With the items ix and iy in these internal cavities, the ix and iy are protected during shipment. The protective structures 378a and 378b are formed from one or more materials to absorb forces that may damage the items ix and iy during shipment. Additionally, the internal cavities determine how the items ix and iy are positioned relative to each other and within a container (as described above) to provide enhanced protection during shipment.
To confirm that the protective structures 378a and 378b have been delivered to the packing location 141, the automatic packing system 140 can evaluate identifiers 379a and 379b provided on the protective structures 378a and 378b, respectively. Similar to the identifiers 135 on the bins 134, the identifiers 379a and 379b may include a barcode and/or other marking. In such a case, the image capture/scanning device 145 on the robotic device 142 may be employed to read the barcode and/or marking to identify the protective structures 378a and 378b. Additionally or alternatively, the identifiers 379a and 379b may include a radio-frequency identification (RFID) or other signal-emitting device that can be used to identify the protective structures 378a and 378b wirelessly.
When the automated packing system 140 determines that the desired items ix and iy and the corresponding protective structures 378a and 378b have been properly delivered to the packing location 141, the automated packing system 140 transfers the items ix and iy from the bins 134a and 134b to the recesses 380a and 380b of the protective structure 370a, respectively. As shown in
The robotic device 142 can employ the image capture/scanning device 145 to capture one or more images of the bins 134a and 134b. The captured images are communicated to the picking/packing controller 106, which can then process the images to identify the bins 134a and 134b as well as the shape, position, and orientation of each item in the bins 134a and 134b. For example, the picking/packing controller 106 can employ object segmentation techniques to identify various shapes in the images and compare the shapes to stored information (e.g., stored images) describing the bins 134a and 134b as well as the items ix and iy. Information on the shape of the items ix and iy may be stored in the item database 06. Accordingly, based on the images captured by the device 145, the robotic device 142 can properly orient itself relative to the bins 134a and 134b to grasp the items ix and iy, respectively. Furthermore, using the captured images, the robotic device 142 can properly orient the grasping device 144 to handle and grasp the items ix and iy appropriately.
As shown in
Using the custom packaging specification 16, the automatic packing system 140 can determine that the first protective structure 378a is configured to protect the items ix and iy from the bottom and the second protective structure 378b is configured to protect the items ix and iy from the top. As such, the robotic device 142 first positions the items ix and iy in the first protective structure 378a and then subsequently places the second protective structure 378b over the items ix and iy.
The robotic device 142 can also employ the image capture/scanning device 145 to capture one or more images of the first protective structure 378a. Based on the information in the captured images, the robotic device 142 can orient itself relative to the first protective structure 378a. In addition, using the captured images, the robotic device 142 can properly orient the grasping device 144 to position the items ix and iy properly relative to the recesses 380a and 380b, respectively. For example, the captured images are communicated to the picking/packing controller 106, which can then process the images to identify the first protective device 378a as well as the shape, position, and orientation of each recess 380a and 380b. In some cases, the picking/packing controller 106 can employ object segmentation techniques to identify the shapes in the images based on the design of the first protective device 378a provided by the custom packaging specification 16.
Additionally or alternatively, markings may be provided directly on the protective devices 378a that can be identified in images captured by the image capture/scanning device 145. These markings allow the picking/packing controller 106 to determine the orientation of the first protective device 378a and identify the recesses 380a and 380b. For instance, as shown in
Knowing where the recess 380a is positioned and oriented relative to the robotic device 142, the grasping device 144 can be controlled to manipulate the olive oil bottle according to one or more six degrees of freedom to position and orient the olive oil bottle relative to the recess 380a and to place the olive oil bottle in the recess 380a. As illustrated in
After the olive oil bottle is transferred to the recess 380a, the robotic device 142 moves the grasping device 144 to the bin 134b to transfer the items iy (the glasses) to the recesses 380b in the protective structure 378a. Using captured image(s) of the bin 134b, the position and orientation of each glass can be determined. As such, the grasping device 144 can be controlled to handle each glass more stably at the bowl rather than, for example, the stem or foot. Once the grasping device 144 grasps the first of the glasses at the bin 134b, the robotic device 142 carries the first glass to the protective structure 378a. Using captured image(s) of the first protective device 378a, the position and orientation of each recess 380b can be determined. Knowing where the recess 380b is positioned and oriented relative to the robotic device 142, the grasping device 144 can be controlled to manipulate the first glass according to one or more six degrees of freedom to position and orient the glass relative to one of the recesses 380b and to place the glass in the first recess 380b. After the first glass is transferred to the first recess 380b, the robotic device 142 similarly transfers the second of the glasses to the second of the recesses 380b in the protective structure 378a.
Once the items ix and iy have been transferred to the first protective structure 380a, the robotic device 142 can place the second protective structure 378b over the first protective 378a. Using captured image(s) of the second protective device 378b, the recesses 380a′ and 380b′ can be identified and their position and orientation relative to the robotic device 142 can be determined. The picking/packing controller 106 can process these captured images in a manner similar to the images captured for the first protective structure 378a. Knowing where the recesses 380a and 380b of the first protective structure 378b are also positioned and oriented relative robotic device, the grasping device 144 can manipulate the second protective structure 378b so that the recesses 380a′ and 380b′ of the second protective structure 378b face downwardly and align with the recesses 380a and 380b of the first protective device 378a. As such, the recesses 380a′ and 380b′ can be placed over the items ix and iy disposed in the recesses 380a and 380b, respectively. When the first protective structure 378a and the second protective structure 378b are combined in this way, the recesses 380a and 380a′ together define an internal cavity for the item ix and the recesses 380b and 380b′ together define internal cavities for the items iy. If required, the protective structures 378a and 378b can be secured together according to any appropriate technique, including, but not limited to, the use of tape, adhesive, string, mechanical/frictional engagement, shrink/stretch wrap, etc. In some embodiments, structural features of the protective structures 378a and 378b allow the robotic device 142 to grasp or otherwise manipulate the protective structures 378a and 378b more easily.
As illustrated in
Alternatively, as shown in
Accordingly, the automated packing system 140 according to the present disclosure can use information from captured images to determine shape, position, and/or orientation of aspects of the bins 134, the items i, and the protective structures 378. Using shape, position, and/or orientation information, the automated packing system 140 can manipulate the items i according to one or more degrees of freedom to place them into recesses 380 of the protective structures 378 according to the custom packaging specification 16. As a result, the automated packing system 140 can position the items i relative to each other and the container 370 to achieve a more optimal arrangement in the three-dimensional space of the container 370.
VI. Example Protective Structure
As described above, the automated packaging manufacturing system 150 can produce one or more custom protective structures for positioning and protecting order items in a container according to a custom packaging specification. For example, as illustrated in
To achieve the rapid manufacturing of custom protective structures, the automated packaging manufacturing system 150 can manufacture a protective structure from a plurality of modular elements. The modular elements are readily and rapidly assembled to form a shape that allows items to be packaged according to a custom packaging specification determined from an analysis of the items. Each modular element acts as a single building block for the protective structure. The automated packaging manufacturing system 150 can manipulate each modular element, e.g., via machine/robotic device, to build a custom shape for the protective structure. Advantageously, because each modular element can be separately manipulated, the amount of material used to form each protective structure can be closely controlled to reduce waste of the material, shipment weight, costs, etc.
The modular elements can adhere to each other to form shapes that can support packaged items during shipment, while also absorbing any shocks, impacts, vibrations, or other external forces that may damage the packaged items. In other words, the adhesion between the modular elements is strong enough, so that the resulting protective structure can maintain the custom shape set forth by the custom packaging specification.
The modular elements may be formed from any material that can support and protect the packaged items. In some cases where the packaged items require more cushioning, the modular elements may be formed from foam rubber, fabricated cellular foam, polyurethane foam, polyethylene foam, polystyrene, elastomeric materials (e.g., gels), etc. Advantageously, the modular elements may be formed from biodegradable materials or agricultural byproducts (e.g., biofibers, mushrooms, or those produced with cornstarch), which are environmentally friendly and may be recycled, composted, or dissolved in water for disposal. Alternative cushioning materials may also include employ a soft outer material filled with air or other gas/fluid. In other cases where the items require less cushioning, the modular elements may be formed from harder plastics or materials.
Preferably, the modular elements are self-adhering, so that they readily adhere to each other when they come into contact. In some cases, an adhesive material is applied to the outer surface of the modular elements to make them self-adhering. For example, a liquid may be applied to the modular elements as they are delivered to the assembly, and the liquid dries/solidifies in time to make the modular elements self-adhering as they come into contact with other modular elements. In addition to applying the adhesive to make modular elements self-adhering prior to contact with other modular elements, adhesives can be additionally/optionally applied after contact to make the adhesion between modular elements stronger.
Strong fast-acting adhesives, such as cyanoacrylate adhesives, can be applied to the modular elements as they are placed into contact with each other. The type of adhesive material may depend on the material from which the modular elements are formed. For instance, a neoprene rubber adhesive (also known as a contact cement/adhesive) may be employed to adhere modular elements that are formed from a nonporous material, such as a plastic or rubber. Or for instance, a synthetic elastomer adhesive (e.g., a spray adhesive) may be employed to adhere modular elements that are formed from a foam.
In some cases, the modular elements can be coated with an adhesive material that provides adhesive properties when it is subsequently treated. For example, a water-activated adhesive may be applied to the outer surface of the modular elements before they are placed into contact with each other. Once the modular elements are positioned to form the protective structure, the modular elements are treated with water so that the adhesive properties of the coating are activated, causing the modular elements to adhere to each other. Water-activated adhesives may be formed from natural polymers from vegetable sources (e.g. dextrins, starches), protein sources (e.g. casein, blood, fish, soybean, milk albumen), animal (e.g. hides, bones), etc. Other water-activated adhesives may be formed from soluble synthetic polymers from polyvinyl alcohol, cellulose ethers, methylcellulose, carboxymethylcellulose, polyvinylpyrrolidone, etc. In other examples, the outer surface of the modular elements can be coated with a heat-activated adhesive or a solvent-activated adhesive and then treated with heat or solvents, respectively, so that the adhesive properties of the coating are activated, causing the modular elements to adhere to each other.
The modular elements can be coated with the unactivated adhesive material and dried before they are positioned to define the protective structure. Advantageously, these modular elements are easier to manipulate during positioning because they are dry and non-adhesive. Once the modular elements are positioned, the adhesive properties can be activated by the subsequent treatment (e.g., application of water, heat, or solvents).
Alternatively, the modular elements may be formed from a material that has inherent adhesive qualities and that readily bonds to itself. For example, the material may be a polymer material with a tackifier which imparts a tackiness or stickiness to the surface of the material (e.g., a material including polymerizing styrene and hydrogenated polyterpene resin as a tackifier). Or for another example, the self-adhering material may employ static electrical forces to cause the material to adhere. By employing a material with inherent adhesive qualities, the application of an additional adhesive material may be unnecessary.
Preferably, the modular elements are quickly combined, e.g., via adhesive(s) and/or inherent adhesive properties, so that the protective structures can be ready by the time the items are in place for packing. In addition, the adhesive qualities on the outer surface of the modular elements preferably dissipate with cooling, drying, curing, etc., after the modular elements are combined, so that the protective device does not continue to be adhering during and after the packing process.
As described above, a voxel-based approach may be employed to produce the custom packaging specification for the protective structure 478. In general, a voxel describes a three-dimensional volumetric pixel, which can be used to break down any geometry according to any desired resolution or scale. As the protective structure 478 can be broken down into individual modular elements 481, each modular element 481 can be conceptually represented by a voxel to develop the custom packaging specification. As shown in
As described herein, the structural aspects of a protective structure can be specified via Cartesian coordinates; however, it is understood that other coordinate systems (e.g., polar coordinate system) and/or other approaches for spatial description may be similarly employed.

The position u of the feeder 452 along the x-axis represents the x-coordinate for the position of a modular element 481; the position v of a modular element 481 along the y-axis represents its y-coordinate; and the position w of the layer 483w along the z-axis represents the z-coordinate for a modular element 481 in the layer 483w. Accordingly, as the feeder 452 passes through the positions (u, v, w), the feeder 452 can deposit each modular element 481 according to the respective Cartesian coordinates (x, y, z) in a voxel-based analysis. Although the example feeder 452 shown in
As
To deposit the row 4824 at position u=4 along the x-axis for the layer 4833 as shown in
The positions v=4, 5, and 6 are empty to define a part of the recess 480 in the protective structure 478. Meanwhile, the positions u=1 and 9 are empty, because the custom packaging specification may determine that packaging material (i.e., a modular element 481) is not required in those positions to provide sufficient support and protection for the item Advantageously, by using modular elements 481 to form the protective structure 478, the automatic packaging manufacturing system 150 can closely control how packaging material is distributed throughout the protective structure 478. As a result, the custom packaging specification can reduce the amount of packaging material used to form the protective structure 478, thereby reducing cost, waste of materials, environmental impact, etc. The voxel-based approach here strikes a balance between practical manufacturing and optimization of material consumption.
As discussed above, an adhesive material may be applied to the outer surface of the modular elements 481 to make them adhere to each other. The adhesive can be applied to the modular elements 481 of a row 482u with a dropper, spray, brush, and/or other applicator. In general, the application of an adhesive and any activation can occur before, during, and/or after the row 482u is placed into contact with other modular elements 481. The modular elements 481 adhere to each other as they are deposited by the feeder 452. When necessary, the automated packaging manufacturing system 150 may allow the modular elements 481 some time to adhere effectively through cooling, drying, curing, etc., after they come into contact with each other.
As shown in corresponding
As shown in
The packaging optimization module 105 may determine that when the protective structures 478 and 478′ are positioned in the container 470, the bottom layer 4831 and the top layer 4831′ provide sufficient protection from any shocks, impacts, vibrations, or other external forces received at the side walls 471b of the container 470. Therefore, as described above, the packaging optimization module 105 may determine that the other layers 4832 and 4833 of the first protective structure 478 and the other layers 4832′ and 4833′ of the second protective structure 478′ do not have to extend to the side walls 471b of the container 470. Fewer modular elements 481 are thus used for the other layers 4832, 4833, 4832′, and 4833′ and space is left unfilled in the container 470. By using modular elements 481 to form the protective structure 478, the automatic packaging manufacturing system 150 can closely control how packaging material is distributed in the container 470. As a result, the custom packaging specification can reduce the amount of packaging material used to form the protective structure 478, thereby reducing shipment weight, waste of materials, cost, environmental impact, etc.
Although
Like the modular elements 481, the modular elements 581 shown in
To produce the protective structure 678, the automated packaging manufacturing system 150 may employ a process similar to the protective structures 478 and 578 described above. However, each modular element size may require a separate feeder and dispenser in the automated packaging manufacturing system 150. As shown in
Because the modular elements 681a-e have different sizes, they can fit in a greater variety of spaces and locations in the protective structure 678. As such, the modular elements 681a-e may be distributed more efficiently and effectively throughout the protective structure 678 compared to protective structures with uniformly shaped modular elements. A voxel-based analysis for the protective structure 678 involves consideration of different volumetric units in the conceptual three-dimensional space.
In
The use of modular elements allows the protective structures to have any shape. In particular, aspects of the present disclosure can provide protective structures that are less conventional in shape. More conventional packaging configurations may employ a size and shape that corresponds closely to the size and shape of the container. For example, if a container (e.g., box) has a rectangular profile with a length l, a width w, and a height h, a conventional packaging configuration may mirror the same rectangular profile and provide a structure with the same length l, width w, and height h around the packaged items. According to aspects of the present disclosure, however, protective structures do not necessarily have the same shape as the container, i.e., the protective structure may have a non-rectangular shape for a rectangular container. As described above with reference to
To allow space to exist between the protective structure and the interior surfaces of the container, the protective devices may include leg-like structures that extend outwardly to engage the interior surfaces of the container and to position the protective structure within the container (e.g., more centrally away from the walls) to enhance protection. These leg-like structures may contribute to the less conventional shape of the protective structure.
In general, aspects of the protective devices may be shaped specifically to reduce amount of packaging material (i.e., modular elements) used for the protective structure. For example, the protective devices may include any number of recesses and/or cavities that are only filled by air. These recesses and/or cavities do not affect the ability of the protective structure to support and protect the packaged items.
Referring to
In addition to defining recesses for receiving and arranging the items for the container 770, the modular elements 781 also define features that allow the protective structure to be securely situated in the container 770. For example, as shown in
To reduce the amount of packaging material used, the protective structures, such as the protective structure 778, may have unconventional shapes. As shown in
Although the modular elements illustrated in
As
The features for arranging items in a three-dimensional space are not limited to recesses. For example, the protective structure 878 shown in
The assembly of the modular elements to form protective structures can be implemented under automatic computer/machine control. As described above, the computing system 101 analyzes an order to produce a custom packaging specification that determines the shape of the protective structures and how modular elements should be assembled to produce the protective structures. In particular, the computer system determines the number of modular elements to use, what different sizes of modular elements to use, and how the modular elements should be positioned relative to each other. The automated packaging manufacturing system 150 may include a machine that can form the desired number of modular elements from a base material according to the desired shapes. Alternatively, the modular elements can be pre-formed in advance and are stored as inventory for subsequent assembly.
The modular particles are then delivered to a machine which can arrange and assemble the modular elements. As described above, a feeder 452, for example, may move along the x-axis to deposit modular elements along the y-axis, and reciprocating movement of the feeder 452 along the x-axis allows the feeder 452 to form layers of modular elements along the z-axis and define the three-dimensional shape of the protective structure. However, the automated packaging manufacturing system 150 is not limited to the use of a device such as the feeder 452. As shown in
In particular,
Meanwhile,
The embodiments described herein may employ computing systems for processing information and controlling aspects of an order system 100. For example, in the computing system 101 shown in
The processor(s) of a computing system may be implemented as a combination of hardware and software elements. The hardware elements may include combinations of operatively coupled hardware components, including microprocessors, communication/networking interfaces, memory, signal filters, circuitry, etc. The processors may be configured to perform operations specified by the software elements, e.g., computer-executable code stored on computer readable medium. The processors may be implemented in any device, system, or subsystem to provide functionality and operation according to the present disclosure. The processors may be implemented in any number of physical devices/machines. For example, the computing system 101 may include one or more shared or dedicated general purpose computer systems/servers to provide the modules 102, 103, 104, and 107 and the controllers 105 and 106. Indeed, parts of the processing of the example embodiments can be distributed over any combination of processors for better performance, reliability, cost, etc.
The physical devices/machines can be implemented by the preparation of integrated circuits or by interconnecting an appropriate network of conventional component circuits, as is appreciated by those skilled in the electrical art(s). The physical devices/machines, for example, may include field programmable gate arrays (FPGA's), application-specific integrated circuits (ASIC's), digital signal processors (DSP's), etc. The physical devices/machines may reside on a wired or wireless network, e.g., LAN, WAN, Internet, cloud, near-field communications, etc., to communicate with each other and/or other systems, e.g., Internet/web resources.
Appropriate software can be readily prepared by programmers of ordinary skill based on the teachings of the example embodiments, as is appreciated by those skilled in the software arts. Thus, the example embodiments are not limited to any specific combination of hardware circuitry and/or software.

Computer program products employed by the example embodiments can include any suitable interpretable or executable code mechanism, including but not limited to complete executable programs, interpretable programs, scripts, dynamic link libraries (DLLs), applets, etc. The processors may include, or be otherwise combined with, computer-readable media. Some forms of computer-readable media may include, for example, a hard disk, any other suitable magnetic medium, CD-ROM, CDRW, DVD, any other suitable optical medium, RAM, PROM, EPROM, FLASH-EPROM, any other suitable memory chip or cartridge, a carrier wave, or any other suitable medium from which a computer can read.
The computing systems may also include databases for storing data. For example, the computing system 101 includes an order database 03 for storing order information and an item database 06 for storing information on items for orders 2. Such databases may be stored on the computer readable media described above and may organize the data according to any appropriate approach. For examples, the data may be stored in relational databases, navigational databases, flat files, lookup tables, etc. Furthermore, the databases may be managed according to any type of database management software.
Although the system 100 determines custom packaging specifications 16 based on the characteristic data 14 of specific items i in an order 02, the determined custom packaging specifications 16 can be stored in a database (e.g., the order database 03) for retrieval when subsequent orders 02 are received for the same specific items i, according to some embodiments of the present disclosure.
While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art.
