Typical prescription medication fulfillment systems process hundreds to thousands of prescriptions a day. These prescription medication fulfillment systems may be used for the online fulfillment of medication prescriptions in instances where patient-specific local pharmacy preparation is not needed. Additionally, some prescription medication fulfillment systems may use conveyance systems to at least help automate operations that may instead be performed a local pharmacies, such as prescription filling and packaging.
As the population continues to age and pharmaceutical companies continue to develop more medications for illnesses, it is inevitable that the distribution points for such medications must become more efficient. From local pharmacies to national drug store chains to large, mail order fulfillment centers that fill tens of millions of prescriptions annually, automation has greatly affected the speed, efficiency, and accuracy of prescription distribution.
It is not surprising that automation results in greater profitability for wholesale and retail pharmacy business owners. Reducing manual operations results in lower payrolls, fewer interruptions in workflow, and greater production predictability. In addition, much of the human error associated with manually filling prescriptions is eliminated. Therefore, reductions in manual operations and human operators creates more efficient and error-free prescription fulfillment operations.
With the development of highly accurate technological mechanisms, including sophisticated hardware and software control systems, there should be little need for human operators to perform some of the repetitive tasks still found in pharmacies. While advancing technology has been applied to large-scale vial filling operations, heretofore such techniques have not been combined with built-in prescription entry and verification features within small, stand-alone units suitable for use in small size pharmacies.
A need accordingly exists for an automated container orienting and sorter system that incorporates advancing technology therein to ensure fast and accurate operations.
Additionally, a need exists for an accurate and efficient machine to assist with medication fulfillment.
Further, a need exists for an automated container orienting and sorter system that is contained within small, stand-alone unis for use in small size pharmacies.
Example systems and apparatus are disclosed herein for sorting and orienting containers. The disclosed systems and apparatus are intended to improve upon previously existing systems and apparatus for sorting and orienting containers.

Additional features and advantages are described in, and will be apparent from, the following Detailed Description and the Figures. The features and advantages described herein are not all-inclusive and, in particular, many additional features and advantages will be apparent to one of ordinary skill in the art in view of the figures and description. In addition, any particular embodiment does not have to have all of the advantages listed herein and it is expressly contemplated to claim individual advantageous embodiments separately. Moreover, it should be noted that the language used in the specification has been selected principally for readability and instructional purposes, and not to limit the scope of the inventive subject matter.
Systems and apparatus are disclosed herein for sorting and orienting containers. Non-limiting embodiments of the present disclosure will be described by way of example with reference to the accompanying figures.
Reference is made herein to medication containers. Medication containers include a variety of containers such as medication bottles, vial carriers, pill packs, blister cards, or other containers for housing and moving medication. The medication held within the medication container may include pills, tablets, or other solid pharmaceutical drug dosage that is consumed by a patient. A medication may also include a compounded pharmaceutical that is prepared from two or more substances. A medication container may include a cylindrical container or a package for housing medication. The medication container described in this application is cylindrical in shape with an open end and a closed end in a vial shape. The open end may couple to a lid to ensure the medication within is secured and not able to be contaminated by exposure to any outside elements. Reference to containers within this application assumes that the lid has not been affixed to the container unless stated otherwise.
Though the present disclosure refers to containers used for packaging medication, it should be appreciated that the described invention may be operable with other articles. For example, the systems, apparatus, and methods may provide for the routing of packages in a facility, products to be packaged in a facility, and/or components to be assembled into a product along an assembly line.
Previously disclosed systems and apparatus for sorting and orienting medication containers are often less efficient than the present disclosure. The present disclosure provides a wide range of sorting and orienting tasks, as the present disclosure can take a collection of unsorted medication containers, transport and sort the medication containers, and dispense individual medication containers that are consistently oriented. In the prior art, several of these steps may have previously required human intervention which may have caused assembly lines to slow.
One specific application that often requires human intervention is the telescoping of medication containers. Telescoping occurs when one container enters into another and the two containers become stuck to one another, rendering at least one container unusable. Telescoped containers may cause stoppages in the process as the telescoped containers may be too large to fit into certain components within the system or be unable to be detected by various sensors. As a result, telescoped containers would previously have to be pulled from the assembly line by a human operator.
The present disclosure prevents the telescoping of containers by using one or more features that ensure each row of an inclined conveyor belt contains a medication container in a horizontal orientation. The present disclosure also prevents telescoping using a partitioned funnel at an end of the conveyor belt that leads to one or more angled or curved queue cylinders. The present disclosure disclosed herein accordingly enables disorganized medication containers placed in a hopper to be placed into a proper orientation for subsequent processing while minimizing opportunities for jamming and telescoping.
Referring now to
Depending on the embodiment, the container singulator apparatus 102, the container sorting apparatus 104, the orientation funnel 106, the container queue apparatus 108, and other components of the container orienting and sorting system 100 may all be physically connected by framing, may be partially connected by framing, or may be physically separated. Additionally, the framing can integrate drawer slides so that the individual components within the container orienting and sorting system 100 can be accessed.
In the illustrated embodiment, a main frame 110 connects the container singulator apparatus 102, the container sorting apparatus 104, the orientation funnel 106, and the container queue apparatus 108. The main frame 110 may consist of metal framing, though it should be appreciated that the main frame 110 may consist of any material appropriate to support the components within the container orienting and sorting system 100. In some embodiments, the main frame 110 may have support structures such as supporting frames like a belt support frame or platforms to support other components within the container orienting and sorting system 100. In yet other embodiments beyond those illustrated, the main frame 110 can be supported by wheels so that the container orienting and sorting system 100 can be easily moved and re-arranged.
In other embodiments, movers such as pneumatic cylinders may be affixed to the main frame 110 to move containers 114 past the container queue apparatus 108 and to further loading and preparing stations. In embodiments with movers, components powering the movers such as motors, actuators, or blowers may be affixed to the main frame 110.
In some embodiments, the container orienting and sorting system 100 is controlled by a controller 147 communicates with a network 149 and a server 151. The controller 147 includes an interface for receiving data and instructions from components such as sensors 144, receiving updates to said instructions, and implementing new instructions. The controller 147 can actuate various components within the container orienting and sorting system 100, which may include motors, pneumatic slides, conveyors, gantries, or valves. For example, in the air sort station embodiment of the container sorting apparatus 104, the controller 147 is communicatively coupled with the flow control 142 and the valve 143 connected to the air nozzle 138. The controller 147 may be a programmable logic controller. The controller 147 also may be local within the container orienting and sorting system 100. In other embodiments, the controller 147 is part of a process control system that remotely communicates with the container orienting and sorting system 100.
The controller 147 is communicatively coupled to a network 149 (e.g., a wide area network, a local area network, a controller area network, a wireless local area network, Ethernet, the Internet, a cellular network, a serial connection such as RS 232 or RS 485, Open Platform Communications (“OPC”), IO-Links, a hardwire connection, or combinations thereof). In the illustrated example, the controller 147 communicates with at least the sensor 144 via the network 149.
The network 149 includes a server 151 and a database of control instructions stored on a memory device. The server 151 may include a memory device that stores machine-readable instructions, which when executed, cause the server 151 to perform the operations disclosed herein. Additionally, the server 151 is communicatively coupled to the memory device, which may include any random access memory (“RAM”), read only memory (“ROM”), flash memory, magnetic or optical disks, optical memory, or other storage media. The memory device is configured to store instructions for controller 147 operations.
In some embodiments, the memory device may store movement instructions regarding the routing of containers 114 in a database. In these embodiments, the server 151 uses an interface to communicate with the container singulator apparatus 102, a container sorting apparatus 104, an orientation funnel 106, and a container queue apparatus 108, and the database in the memory device, as described further below.
Affixed to the main frame 110 is a transport mechanism. The transport mechanism is configured to receive medication containers 114 from a loading section 116 and is able to receive more than one container 114 contemporaneously. The containers 114 may be fed into the transport mechanism from the loading section via a belt support having a first end located adjacent to a loading section and a second end located a fixed distance from the loading section, the belt support including a belt track and a cam track. In other embodiments, the containers 114 may be fed into the transport mechanism from the loading section 116 in a variety of manners, including but not limited to, manually feeding, conveying by conveyor belt or dial machine indexer, or rolling the medication containers 114 down ramps. In other embodiments, the containers 114 may be received directly by the transport mechanism itself.
The transport mechanism and other moveable components in the container orienting and sorting system 100 are powered by a motor or other related actuator. It should be appreciated that the motor identified within the application is purely exemplary and that other motors or actuators may be added or omitted in other embodiments of the container orienting and sorting system 100.
The transport mechanism may be any mechanism capable of moving the containers 114 from a first end by the loading section 116 to a second end located at a fixed distance from the loading section 116 at a dispense section 118. This may include, but is not limited to, a belt conveyor system, a walking beam conveyor system, a plurality of rollers, a dial machine indexer, or pneumatic tubing.
In the illustrated embodiments, the transport mechanism is a cleated belt conveyor track 120. As shown in
Cleats 122 on the cleated belt conveyor track 120 may contain multiple containers 114. Additionally, the containers 114 may be oriented in a variety of positions. Containers 114 oriented in a horizontal direction with respect to the cleat 122 lie with the circular ends of a cylindrical container tangential to the conveyor belt (i.e., with the height of the container parallel to the length of the cleat). Containers 114 oriented in a vertical direction with respect to the cleat 122 lie with an open end of the container 114 perpendicularly facing outwards from the cleat 122. It is preferred that the entire conveyor is wide enough to hold at least two containers 114 in a horizontal orientation (i.e., parallel to the cleats).
As the containers 114 exit the loading section 116 and are directed upward by the cleated belt conveyor track 120, the containers 114 encounter a push plate 124. The push plate 124 can be any material suitable to push the empty containers 114 that come into contact with the push plate 124. As one such example, the push plate 124 may be a metal. As shown in
The push plate 124 has a first surface parallel to the width of the cleated belt conveyor track 120. The first surface contains a push edge 132 that forms an angle with the edge of the conveyor belt. The angle of the push edge 132 causes the width of the cleated belt conveyor track 120 to increase from the bottom end of the cleated belt conveyor track 120 (i.e., by the loading section) to the top end of the cleated belt conveyor track 120 (i.e., by the dispense station). The push edge 132 should be dull enough to ensure the containers 114 are not broken or damaged upon contact with the push edge 132. At the highest height of the push plate 124, the push plate 124 should extend far enough along the width of the cleated belt conveyor track 120 that the push plate 124 is configured to enable a single container 114 in the horizontal orientation to pass through on the cleated belt. As a result, the angle of the push edge 132 directs containers 114 towards one particular side of the cleated belt conveyor track 120. In the illustrated embodiment of
Optionally, the container singulator apparatus 102 may further include a divider 126. The divider 126 is intended to push containers 114 that are in the vertical direction towards an edge of the cleated belt conveyor track 120 and off of the cleated belt conveyor track 120. In the illustrated embodiment, the divider 126 is intended to push containers 114 in the vertical direction to the left side of the cleated belt conveyor track 120 (i.e., with the height of the containers 114 perpendicular to the length of the cleat 122). Thus, the divider 126 is intended to ensure all containers 114 are oriented in the same direction.
The divider 126 is positioned between the bottom end of the cleated belt conveyor track 120 and the top end of the cleated belt conveyor track 120. The divider 126 extends outward from the cleated belt conveyor track 120 at a distance farther than the push plate 124, but close enough so that containers 114 oriented in the vertical direction may be knocked off by the divider 126. The divider 126 can be any material suitable to push the empty containers 114 that come into contact with the divider 126. As one such example, the divider 126 may be a metal.
The divider 126 has an arm extending at an angle from the edge of the cleated belt conveyor track 120. In some embodiments, this angle may be the same as the angle of the push edge 132. In other embodiments, the divider 126 is at an angle greater than or less than the angle of the push edge 132 with respect to the edge of the cleated belt conveyor track 120. An ideal divider 126 angle is one that successfully pushes vertical containers 114 off of the cleated belt conveyor track 120. If the divider 126 is too horizontal (i.e., closer to parallel with the cleats 122), the containers 114 may not be pushed off of the cleated belt conveyor track 120 and instead may become stuck to the divider 126 as the cleated belt conveyor track 120 continues to move causing a jam or disruption in the process. If the divider 126 is too vertical (i.e., closer to perpendicular with the cleats 122), the divider 126 must become longer to ensure all containers 114 along any portion of the length of a cleat 122 may pass by the divider 126. If the divider 126 is longer, the cost of the design increases. Therefore, the ideal divider angle 126 is between 0° and 90° with respect to the cleats 122 on the cleated belt conveyor track 120.
Depending on the embodiment, the divider 126 may be adjacent to or above the push plate 124. In embodiments where the divider 126 is adjacent to the push plate 124, such as the illustrated embodiment shown in
A top end of the divider 126 is located on the side closest to the dispense section 118, and in the illustrated embodiments where the divider 126 meets with the ramp 128. The divider 126 pushes containers 114 in a vertical direction to the ramp 128. The ramp 128 can be any material suitable to push the empty containers 114 that come into contact with the ramp 128. As one such example, the ramp 128 may be a metal.
The ramp 128 is positioned adjacent to the left side of the cleated belt conveyor track 120. Like the push plate 124 and the divider 126, the ramp 128 is also positioned between the bottom end of the cleated belt conveyor track 120 and the top end of the cleated belt conveyor track 120. The ramp 128 extends perpendicularly outward from the cleated belt conveyor track 120 to create a barrier for containers 114 approaching the left side of the cleated belt conveyor track 120. As containers 114 approach the ramp 128, any container 114 that is extending off of the edge of the cleated belt conveyor track 120 (i.e., the length of the containers 114 not fully contained on the cleat 122), as an example, due to the push plate 124 or the divider 126 moving the container 114 beyond the edge, is pushed off by the ramp 128. The ramp 128 exerts downward force onto the container 114 extending off of the edge of the cleated belt conveyor track 120. Containers 114 having a length oriented entirely on the cleated belt conveyor track 120 pass by the ramp 128 without ever coming into contact with the ramp 128.
In some embodiments, the container singulator apparatus 102 includes a guide plate 130. The guide plate 130 is affixed to the side of the cleated belt conveyor track 120 where containers 114 fall off by forces exerted by the push plate 124, the divider 126, or the ramp 128. The guide plate 130 may be affixed to the main frame 110. The guide plate 130 may be coupled through the use of screws, nails, or other coupling mechanisms. It should be appreciated that the identified coupling mechanisms in the application are exemplary and other coupling mechanisms may be added or omitted in other embodiments of the container singulator apparatus 102. The guide plate 130 may be any material suitable to guide the empty containers 114 towards the loading section 116. As one such example, the guide plate 130 may be a metal.
The purpose of the guide plate 130 is to direct containers 114 back to the loading section 116 to be properly reloaded onto the cleated belt conveyor track 120. In some embodiments such as the illustrated embodiment, the guide plate 130 may be curved on the side farthest from the cleated belt conveyor track 120 to allow containers 114 to be guided back to the loading section 116. In other embodiments, the guide plate 130 may include multiple sheets components creating a ramp and sidewall for the containers 114. It will be appreciated that other configurations of the guide plate may be used with the container orienting and sorting system 100.
Upon exit from the container singulator apparatus 102, the containers 114 remain on the cleated belt conveyor track 120 with each cleat 122 containing one container 114. In embodiments where containers 114 are cylindrical containers such as pill vials, the containers 114 must then be sorted based on orientation. This application refers to containers 114 with the open end facing the left side of the illustrated embodiments, or the guide plate 130, as the left position (illustrated by 114a) and containers 114 with the open end facing the right side of the illustrated embodiments, or the push plate 124, as the right position (illustrated by 114b). As a container 114 has both an open end and a closed end, containers 114 on different cleats 122 may be facing different directions and be in different orientations than those on other cleats 122. As a result, a container sorting apparatus 104 is needed to ensure that all containers on the cleated belt conveyor track 120 are facing a homogenous direction. This application describes two container sorting apparatuses 104: the air sort station 134 as shown in
The present disclosure further includes a method for aggregating and sorting containers in a container singulator apparatus 700 as illustrated in
The air nozzle 138 is located adjacent to a side of the cleated belt conveyor track 120. In the illustrated embodiment, it is located adjacent to the left side of the cleated belt conveyor track 120. The air nozzle 138 is configured to blow pressurized air perpendicularly towards the cleated belt conveyor track 120 and onto passing containers 114. If a container 114 has its open end facing away (114b) from the air nozzle 138, the air nozzle 138 blows pressurized air onto the bottom edge of the container 114 and pushes the container 114 into the middle or right side of the cleat 122. A bumper rail 140 located on the side of the cleated belt conveyor track 120 opposite the air nozzle 138 prevents containers 114 from being blown off of the cleated belt conveyor track 120. In some embodiments, the bumper rail 140 may extend below the height of the air nozzle 138. Thus, the containers 114 are optimally divided with containers 114 facing one orientation on one side of the cleated belt conveyor track 120 and containers 114 facing another orientation on the other side of the cleated belt conveyor track 120.
The air nozzle 138 is connected to a pressurized air source and is controlled by a flow control 142 and a valve 143. The flow control 142 is fluidly coupled between the pressurized air source and the air nozzle 138 and is configured to direct the flow of pressurized air. In some embodiments, the flow control 142 is controlled by a controller 147, which is communicatively coupled to a sensor 144. The controller 147 receives data from the sensor 144 and transmits control instructions to the flow control 142 as to whether the flow of compressed air should be increased or decreased.
In some embodiments, there may be multiple air nozzles 138. In embodiments with multiple air nozzles 138, each air nozzle 138 is coupled to at least one flow controls 142, valves 143, and sensors 144.
Similarly, at least one valve 143 is fluidly coupled between the pressurized air source and the air nozzle 138 and is configured to regulate the flow of pressurized air. The valve 143 is controlled by a controller 147 which is communicatively coupled to a sensor 144. The controller 147 receives data from the sensor 144 and transmits control instructions to the air nozzle 138 as to whether the air nozzle 138 should blow pressurized air. The number of valves 143 may vary. As shown in
When a container 114 on the cleat 122 passes by the air nozzle 138, the controller 147 determines the proper course of action based on data from the sensor 144 regarding the container's 114 orientation and other parameters. The controller 147 then sends movement instructions to the valve to initiate one of two courses of action.
If the sensor 144 senses an open end of the container 114a passing the air nozzle 138 on the edge of the cleated belt conveyor track 120, the controller 147 determines that the valve 143 should not open and allows the container 114a to pass the direction of the air nozzle 138 without any pressurized air blown. The container 114a remains on the side of the cleated belt conveyor track 120 located closest to the air nozzle 138. In the illustrated embodiment, the container 114a remains on the left side of the cleated belt conveyor track 120.
If the sensor 144 senses a closed end of the container 114b passing the air nozzle 138 on the edge of the cleated belt conveyor track 120, the controller 147 determines that the valve 143 should open and transmits a signal to the valve 143 to open. Once opened, the air nozzle 138 blows pressurized air towards the container 114b thereby pushing the container 114b toward the opposite edge of the cleated belt conveyor track 120. The container 114b moves laterally in the direction toward the bumper rail 140.
In another embodiment, the sensor 144 may merely communicate that the cleat 122 or container 114 has passed by the sensor 144 and a lesser amount of air is blown onto all containers 114 on the cleated belt conveyor track 120. In this embodiment, containers 114 with open ends facing left, will be unaffected by the air as the flow of pressurized air is weakened from other embodiments.
The type of sensor 144, the location of the sensor 144, and the force of the pressurized air from the air nozzle 138 may all be adjusted to adjust the distance the container 114 travels laterally from the flow of air. For instance, the sensor 144 may be an optical sensor, a micro switch, or any sensor appropriate to determine the orientation of the container 114. In the illustrated embodiment, the sensor 144 is an optical sensor located upstream from the air nozzle 138, though it should be appreciated that the identified sensor mechanisms in the application are exemplary and other sensor mechanisms may be added or omitted in other embodiments of the container sorting apparatus 104.
The present disclosure further includes a method for aggregating and sorting containers in a container sorting apparatus 1200 as illustrated in
The cam belt 146 is configured to transport cam-driven probes 148 along a conveyor belt and is adjacent to the cleated belt conveyor track 120. In some embodiments, the cam belt 146 may be touching the cleated belt conveyor track 120. In yet other embodiments, cam belt 146 and the cleated belt conveyor track 120 may be the same conveyor belt. The cam belt 146 is powered by a motor or other related actuator. In some embodiments, this motor powers both the cleated belt conveyor track 120 and the cam track 150. It should be appreciated that the motor identified within the application is purely exemplary and that other motors or actuators may be added or omitted in other embodiments of the mechanical probe sort station 136.
The cam belt 146 includes individual rows that are spaced the same distance as the cleats 122 on the cleated belt conveyor track 120 such that the rows are aligned with the rows of the cleated belt conveyor track 120. At the center of each row of the cam belt 146 is one cam-driven probe 148.
As shown in
The sleeve 154 is a three-sided rod creating a protrusion that acts as a housing to the L-shaped rod 156. The L-shaped rod 156 fits between two faces of the sleeve 154. The other end of the L-shaped rod 156 is a roller 158 configured to fit between the sides of the cam track 150 such that a cam-driven probe 148 may travel along the cam track 150.
The cam track 150, which holds the roller 158 of the L-shaped rod 156 of the cam-driven probes 148 controls the distance the L-shaped rod 156 extends toward the cleated belt conveyor track 120 and thus how far the cam-driven probes 148 probe the containers 114. In the illustrated embodiment, the cam track 150 has a v-shaped path that when the roller 158 of the L-shaped rod 156 travels, it pushes the cam-driven probe 148 outward over the cleated belt conveyor track 120 while traveling the first portion of the v-shape and retracts along the second portion of the v-shape. It will be appreciated that the path of the cam track 150 is purely exemplary and other configurations of the path of the cam track 150 may exist.
Similar to the air sort station 134 described above, the mechanical probe sort station 136 is configured to separate containers 114 by orientation and extend perpendicularly into the containers 114. Containers with open ends pointing in toward the left side (i.e., nearest the air nozzle 138 or cam-driven probes 148) 114a remain on the left side of the cleated belt conveyor track 120 and containers with open ends pointing in the other direction (i.e., farthest from the air nozzle 138 or cam-driven probes 148) 114b are moved to the right side of the cleated belt conveyor track 120. In the illustrated embodiment, the cam belt 146 is to the left of the cleated belt conveyor track 120 and thus the cam track 150 drives the cam-driven probes 148 to the right. As a result, and as shown in
It should be appreciated that other camming mechanisms may be operable with the mechanical probe sort station 136. Other embodiments may use different cam mechanisms to mechanically probe the containers 114. In one such example, the cam-driven probes 148 and cam track 150 may be replaced with a one-sided face cam with a spring configured to push a similar cam-driven probe into the containers 114. The face cam may contain internal holes which can mechanically couple to a probe that allows the rotary motion of the cam to transform into a linear probing motion. In this embodiment, the face cam may be powered by a motor or other related actuator, or may be mechanically powered by a spring. In another example, the cam-driven probes 148 may be replaced with pivot arms that contain at least two independently moving portions. When one end of the pivot arm follows the cam track 150, it causes motion in the other pivot arm which may be configured to linearly probe the containers 114 on the cleated belt conveyor track 120. It should be appreciated that the cam mechanisms described herein are purely exemplary and other such cam mechanisms may be identified by persons having ordinary skill in the art.
The present disclosure further includes a method for aggregating and sorting containers in a container sorting apparatus 1700 as illustrated in
Returning to
The entrance section 160 of the orientation funnel 106 is located at the top end of the orientation funnel 106 and is where containers 114 enter from the cleated belt conveyor track 120. In the illustrated embodiments, the entrance section 160 has an entrance width that is at least as long as two container lengths. Preferably, the width of the entrance section 160 is the same width of the cleated belt conveyor track 120 to ensure that all containers 114 regardless of positioning on the cleated belt conveyor track 120 fall into the orientation funnel 106.
As the container 114 exits the cleated belt conveyor track 120, the container 114 enters either a first or second path. In the illustrated embodiment, the first path is located on the left side of the orientation funnel 106 and catches containers 114 that have been pushed by the air nozzle 138 or the cam-driven probes 148 (114a). The second path is located on the right side of the orientation funnel 106 and catches containers 114 that have not been pushed by either the air nozzle 138 or the cam-driven probes 148 (114b).
The entrance section 160 also has a bend between 60° and 120° that transitions the orientation funnel 106 from a horizontal orientation to a vertical orientation. It should be appreciated that the bend in the entrance section 160 may differ depending on the orientation and size of the cleated belt conveyor track 120. For instance, if the cleated belt conveyor track 120 is taller and has a steeper incline, the bend in the entrance section 160 may be minimal in attempt to assist containers 114 in a slower and more coordinated fall into the entrance section 160.
In the vertical orientation is the mid-section 162 of the orientation funnel 106. The mid-section 162 of the orientation funnel 106 is contained between the entrance section 160 and the exit port 164. The mid-section 162 has a transitioning width that transitions from the entrance width to an exit port width. This tapering causes containers 114 to rotate from a horizontal orientation to a vertical orientation as the container 114 falls from the entrance section 160 to the exit port 164 by acting as a slide for the containers 114. As the containers 114 rotate to a vertical orientation, the closed end of the container 114 falls first due to that side's heavier weight. When containers 114 exit the mid-section 162, the containers 114 are in a vertical orientation with the open end facing upwards regardless of which path the container 114 took.
After traveling through the mid-section 162, the containers 114 enter the exit port 164 located at the bottom end of the orientation funnel 106. The exit port 164 is vertically oriented below the top end of both the entrance section 160 and the mid-section 162 of the orientation funnel 106. The exit port 164 has an exit port width that is less than the entrance width which is configured to enable only containers 114 in the vertical orientation to pass through. The exit port 164 is coupled the container queue apparatus as shown in
As shown in
In the illustrated embodiment, the second sensor 167 is oriented towards the cleated belt conveyor track 120 to determine is any container 114 on the cleated belt conveyor track 120 is stuck in any predetermined undesired position. If the second sensor 167 detects that a container 114 is located in the predetermined undesired position, the second sensor 167 communicates with the controller. In some embodiments, the controller 147 may stop the container orienting and sorting system 100 until the container 114 in the predetermined undesired position is removed.
With both the first and second sensors 165, 167, the type of sensor and the location of the sensor may be adjusted. For instance, the sensors 165, 167 may be optical sensors, micro switches, or any other sensors appropriate. In the illustrated embodiment, both the first and second sensors 165, 167 are optical sensors, though it should be appreciated that the identified sensor mechanisms in the application are exemplary and other sensor mechanisms may be added or omitted in other embodiments of the container orienting and sorting system 100.
The present disclosure further includes a method for aggregating and sorting containers in a funnel apparatus 2200 as illustrated in
Upon exiting the orientation funnel 106, the containers 114 enter the container queue apparatus 108 as shown in
The container queue apparatus 108 includes a drive shaft 168, at least two queue cylinders 170, a switch tube 172, at least one stop actuator 174, and a hold actuator 176. In some embodiments, the container queue apparatus 108 including the queue cylinders 170, the switch tube 172, the stop actuator 174, and the hold actuator 176, is contained on a platform 178 attached to the main frame 110. The platform 178 may consist of metal framing, though it should be appreciated that the platform 178 may consist of any material appropriate to support the components within the container orienting and sorting system 100.
Toward the top end of the container queue apparatus 108 is the switch tube 172. The switch tube 172 has an input end 180 and an output end 182. The input end 180 of the switch tube 172 is adjacent to the exit port 164 of the orientation funnel 106 so that containers 114 pass directly from the exit port 164 into the switch tube 172. The switch tube 172 then bends towards the output end 182 at an angle that still allows the containers 114 to pass through from the exit port 164. The bend may be helical so as to cause the containers 114 to ride along the inner edges of the switch tube 172 instead of falling vertically and risking telescoping into another container 114. The output end 182 of the switch tube 172 aligns with the top end 184 of a queue cylinder 170 and the containers 114 continue to pass through to the queue cylinder 170.
The queue cylinders 170 are positioned in a vertical orientation and a located adjacent to one another. The top ends of each queue cylinder 170 are at the same height. In some embodiments, there are two queue cylinders 170. In other embodiments, there may be four queue cylinders 170. It should be appreciated that the number of queue cylinders 170 in the container queue apparatus 108 may differ in other embodiments. The number of queue cylinders 170 may depend on the how fast the container orienting and sorting system 100 requires containers 114 to pass through the container queue apparatus 108 and how fast the drive shaft 168 may go. The use of four queue cylinders 170 in the description below is purely exemplary.
The queue cylinders 170 are configured to enable containers 114 to pass through. While the shape of the queue cylinders 170 may vary, the queue cylinders 170 are shaped such that the containers 114 may ride along the inner edges of the queue cylinder 170 instead of falling vertically and risking telescoping into another container 114. In the illustrated embodiment, the queue cylinders 170 have a partial twist that creates a helical shape.
A sensor 144 is configured to detect when a queue cylinder 170 fills with containers 114. The type of sensor 144 and the location of the sensor 144 may vary. For instance, the sensor 144 may be an optical sensor, a micro switch, or any sensor appropriate to determine when the queue cylinder 170 is full. In one such embodiment, the sensor 144 is an optical sensor located at a distance from the queue cylinder 170 pointed perpendicularly to the top end 184 of the queue cylinder 170. When the optical sensor detects a container 114 that remains within the queue cylinder 170 for a predetermined period of time, such as a half of a second, the sensor 144 sends instructions to the drive shaft 168 that the queue cylinder 170 is full. It should be appreciated that the identified sensor mechanisms in the application are exemplary and other sensor mechanisms may be added or omitted in other embodiments of the container queue apparatus 108.
The sensor 144 is communicatively coupled to a controller. This controller 147 may be the same controller 147 used in the air sort station 134 or may be a second controller 147 independent of the air sort station 134 controller. The controller 147 can actuate various components within the container orienting and sorting system 100 which may include motors, pneumatic slides, conveyors, gantries, or valves. Here, the controller 147 is communicatively coupled with a drive shaft 168.
When one queue cylinder 170 fills with containers 114, the controller 147 sends movement instructions to the drive shaft 168 which rotates the switch tube 172 about the drive shaft 168 to align with the top end of a different queue cylinder 170. The top end 184 of the switch tube 172 remains aligned with the exit port 164 of the orientation funnel 106. The output end 182 of the switch tube 172 aligns with the top end of a different queue cylinder 170 which allows the second queue cylinder 170 to fill with containers 114. In some embodiments, the switch tube 172 may be placed within a cylindrical hole of a lid 186. The lid 186 is used to cover all other top ends 184 of queue cylinders 170 while the queue cylinders 170 are not in use. The cylindrical hole of the lid 186 allows containers 114 to pass through the switch tube 172 into the currently aligned queue cylinder 170.
The drive shaft 168 is provided in a vertical orientation. In the illustrated embodiment, the drive shaft 168 is affixed to the platform 178. The queue cylinders 170 may be positioned on opposing sides of the drive shaft 168. The switch tube 172 is connected to an end of the drive shaft 168 such that the switch tube 172 rotates when the drive shaft 168 is in operation. The drive shaft 168 is powered by a motor or other related actuator. In some embodiments, the motor is the same as the motor that powers both the cleated belt conveyor track 120 and the cam track 150. In other embodiments, the motor is an independent motor that operates separately from the motor powering the cleated belt conveyor track 120 and the cam track 150. It should be appreciated that the motor identified within the application is purely exemplary and that other motors or actuators may be added or omitted in other embodiments of the container queue apparatus 108. In other embodiments, the drive shaft 168 may be replaced with air cylinders, hydraulic cylinders, or solenoids to move the switch tube 172.
In some embodiments, the container queue apparatus 108 includes at least one hold actuator 176 located at a bottom end 188 of the queue cylinder 170. There may be a hold actuator 176 for each queue cylinder 170. The hold actuator 176 may be a pneumatic cylinder or other mechanism capable of suspending the flow of containers 114 down the container queue apparatus 108. In embodiments where the hold actuator 176 is a pneumatic cylinder, the pneumatic cylinder arm extends perpendicularly into the bottom end 188 of the queue cylinder 170 to catch containers 114 from falling out the bottom end of the queue cylinder 170.
Similarly, below the hold actuators 176 and further down the bottom end 188 of the queue cylinder 170 is at least one stop actuator 174. There may be a stop actuator 174 for each queue cylinder 170. The stop actuator 174 is positioned adjacent to a bottom end 188 of the respective queue cylinder 170 and configured to release a container 114 located at the bottom end 188 of the at least two queue cylinders 170 when in an open position. The stop actuator 174 may be a pneumatic cylinder or other mechanism capable of suspending the flow of containers 114 down the container queue apparatus 108. In embodiments where the stop actuator 174 is a pneumatic cylinder, the pneumatic cylinder arm extends perpendicularly into the bottom end 188 of the queue cylinder 170 to catch containers 114 from falling out the bottom end 188 of the queue cylinder 170.

As shown in greater detail in
In yet other embodiments, such as the embodiments illustrated by
In some embodiments, the manifold 192 may include doors 195 that allow access to the internal components of the pneumatic air lock unit 190. The doors 195 may be coupled to the manifold 192 through the use of hinges or other coupling mechanisms. It should be appreciated that the identified coupling mechanisms in the application are exemplary. In some embodiments, the doors 195 may cover holes within the manifold 192. In the embodiment illustrated in
The manifold 192 includes at least one feed port 196, at least one inlet port 198, and at least outlet port 200. As shown in
The feed port 196 is configured to allow containers 114 to enter into the pneumatic air lock unit 190. In the illustrated embodiments, containers 114 enter the feed port 196 through an entry system such as an entry tube 202 oriented such that gravity guides the containers 114. It should be appreciated that the entry tube 202 identified within the application is purely exemplary and that entry systems may be added or omitted in other embodiments of the container orienting and sorting system 100. The entry system may be any mechanism capable of moving the containers 114 from the bottom end 188 of the queue cylinder 170 to the pneumatic air lock unit 190. This may include, but is not limited to, a belt conveyor system, a walking beam conveyor system, a plurality of rollers, or a dial machine indexer.
Once inside the manifold 192, the containers 114 are placed within a transport mechanism 204 having a first position adjacent to the feed port 196. In the illustrated embodiments, the transport mechanism 204 is a tube configured to hold the containers 114. It should be appreciated that the transport mechanism 204 may be any mechanism capable of moving the containers 114 within the manifold 192. This may include, but is not limited to, a belt conveyor system, a walking beam conveyor system, a plurality of rollers, or a dial machine indexer.
The transport mechanism 204 is configured to move from the first position that is aligned with the feed port 196 to a second position that is aligned with the inlet port 198 and the outlet port 200 such that containers 114 may travel from a feed port 196 through an outlet port 200. The transport mechanism 204 utilizes an actuator 205. In the illustrated embodiment, the actuator 205 may be a pneumatic cylinder coupled to a motor, but it should be appreciated that the actuator identified within the application is purely exemplary and that other actuators may be added or omitted in other embodiments of the pneumatic air lock unit 190. The actuator 205 may be communicatively coupled with the controller 147 configured to send movement instructions to the actuator.
The inlet port 198 and outlet port 200 allow pressurized air to pass through the pneumatic air lock unit 190 with air entering the inlet port 198 and flowing through the outlet port 200. Within the manifold 192, the inlet port 198 and outlet port 200 are adjacent to at least one pass-through tube 201 in a first position. The pass-through tube 201, which is also coupled to the actuator 205, moves from a first position that is aligned with the inlet port 198 and outlet port 200 to a second position away from the inlet port 198 and outlet port 200. The pass-through tube 201 allows the pressurized air to pass through the pneumatic air lock unit 190 at all times when the transport mechanism 204 is the first position capable of receiving new containers 114 from the feed port 196, minimizing air leakage.
Both the pass-through tube 201 and the transport mechanism 204 are mounted to the same actuator 205. When the transport mechanism 204 receives a container 114 from the inlet port 198, the transport mechanism 204 is pushed from the first position to the second position adjacent to the inlet port 198 and outlet port 200 and the pass-through tube 201 is pushed to the side of the inlet port 198 and outlet port 200. Both the pass-through tube 201 and transport mechanism 204 fit tightly between the inlet port opening and the outlet port opening of the manifold 192. Although it is not an air-tight seal, the clearance is small enough and the pressure from the air nozzle is low enough that there is minimal air leakage.
In the illustrated embodiment, the inlet port 198 and outlet port 200 are affixed to air flow tubes 206, which receive air from an air nozzle. The air nozzle is configured to blow pressurized air strong enough to move the containers 114 through the air flow tubes 206. In some embodiments, the air nozzle is configured to flow pressurized air through the inlet ports 198 and the outlet ports 200. In some embodiments, the air nozzle is connected to a pressurized air source and is controlled by a flow control and a valve. In some embodiments, the flow control and valve may be the same as the flow control 142 and valve 143 of the air sort station 134 illustrated in
In some embodiments, the controller 147 may be configured to transmit control instructions to the flow control to turn off any pressurized air flow while the transport mechanism 204 moves between the first position and the second position so as to not allow pressurized air to escape. In alternative embodiments, there may be a door affixed to the inlet port 198 and/or the outlet port 200 communicatively coupled to the controller 147. The controller 147 may transmit control instructions to shut the door while the transport mechanism 204 moves between the first position and the second position, thereby blocking pressurized air from entering the pneumatic air lock unit 190.
The transport mechanism 204 is configured to move from the first position that is aligned with the feed port 196 to the second position that is aligned with the inlet port 198 and outlet port 200 (and thus the air flow tubes 206) by an actuator 205 coupled to the transport mechanism 204. Once the transport mechanism 204 is in the second position, any container 114 in the transport mechanism 204 exits the outlet port 200 of the manifold 192 when the air nozzle blows pressurized air through the air flow tubes 206. In some embodiments, sensors 208 directed toward the outlet port 200 may identify when containers 114 exit the outlet port 200. Once the sensors 208 detect a container 114 exiting the outlet port 200, the sensor 208 is configured to transmit a signal to the controller 147, which causes the actuator to move the transport mechanism 204 back to the first position to allow the transport mechanism 204 to receive another container 114 entering the pneumatic air lock unit 190.
The type of sensor 208 and the location of the sensor 208 may vary. For instance, the sensor 208 may be an optical sensor, a micro switch, or any sensor appropriate to determine the movement of a container 114 through the outlet port 200. In the illustrated embodiment, the sensor 208 is an optical sensor affixed to the manifold 192, though it should be appreciated that the identified sensor mechanisms in the application are exemplary and other sensor mechanisms may be added or omitted in other embodiments of the pneumatic air lock unit 190.
The pneumatic air lock unit 190 may comprise multiple feed ports 196, inlet ports 198, outlet ports 200, and transport mechanisms 204 to allow multiple containers 114 to be transported by the pneumatic air lock unit 190 at once. The illustrated embodiment includes four feed ports 196, four inlet ports 198, four outlet ports 200, and four transport mechanisms 204. It should be appreciated that the number of individual components in the pneumatic air lock unit 190 may differ in other embodiments. The number of components may depend on the how fast the pneumatic air lock unit 190 requires containers 114 to pass through and how fast the actuator 205 may go. The number of internal components in the description below is purely exemplary. Additionally, in embodiments with multiple transport mechanisms 204, each transport mechanism 204 may independently move from its first position to its second position and may operate individually or in tandem.
In some embodiments, sensors in communication with the controller 147 may be included at the exit location so that only one container 114 may travel in the air flow tubes 206 at a time. Sensors directed toward the exit location may identify when containers 114 arrive at the exit location. Once the sensors detect a container 114 at the exit location, the sensor can transmit a signal to the controller 147, which allows the actuator to move the transport mechanism 204 from the first position to the second position, allowing another container 114 to pass through the air flow tubes 206.
It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present subject matter and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
