PACKAGING MACHINE AND SYSTEMS

BACKGROUND
1. The Field of the Invention

Exemplary embodiments of the disclosure relate to systems, methods, and devices for packaging items into boxes. More specifically, exemplary embodiments relate to packaging machines that maintain an arrangement of one or more items and fold and secure a custom box template around the item(s) to package the item(s) in a custom box.

2. The Relevant Technology

Shipping and packaging industries frequently use paperboard and other sheet material processing equipment that converts sheet materials into box templates. One advantage of such equipment is that a shipper may prepare boxes of required sizes as needed in lieu of keeping a stock of standard, pre-made boxes of various sizes. Consequently, the shipper can eliminate the need to forecast its requirements for particular box sizes as well as to store pre-made boxes of standard sizes. Instead, the shipper may store one or more bales of fanfold material, which can be used to generate a variety of box sizes based on the specific box size requirements at the time of each shipment. This allows the shipper to reduce storage space normally required for periodically used shipping supplies as well as reduce the waste and costs associated with the inherently inaccurate process of forecasting box size requirements, as the items shipped and their respective dimensions vary from time to time.

In addition to reducing the inefficiencies associated with storing pre-made boxes of numerous sizes, creating custom sized boxes also reduces packaging and shipping costs. In the fulfillment industry it is estimated that shipped items are typically packaged in boxes that are about 65% larger than the shipped items. Boxes that are too large for a particular item are more expensive than a box that is custom sized for the item due to the cost of the excess material used to make the larger box. When an item is packaged in an oversized box, filling material (e.g., Styrofoam, foam peanuts, paper, air pillows, etc.) is often placed in the box to prevent the item from moving inside the box and to prevent the box from caving in when pressure is applied (e.g., when boxes are taped closed or stacked). These filling materials further increase the cost associated with packing an item in an oversized box.

Customized sized boxes also reduce the shipping costs associated with shipping items compared to shipping the items in oversized boxes. A shipping vehicle filled with boxes that are 65% larger than the packaged items is much less cost efficient to operate than a shipping vehicle filled with boxes that are custom sized to fit the packaged items. In other words, a shipping vehicle filled with custom sized packages can carry a significantly larger number of packages, which can reduce the number of shipping vehicles required to ship the same number of items. Accordingly, in addition or as an alternative to calculating shipping prices based on the weight of a package, shipping prices are often affected by the size of the shipped package. Thus, reducing the size of an item's package can reduce the price of shipping the item. Even when shipping prices are not calculated based on the size of the packages (e.g., only on the weight of the packages), using custom sized packages can reduce the shipping costs because the smaller, custom sized packages will weigh less than oversized packages due to using less packaging and filling material.

Although sheet material processing machines and related equipment can potentially alleviate the inconveniences associated with stocking standard sized shipping supplies and reduce the amount of space required for storing such shipping supplies, previously available machines and associated equipment have various drawbacks.

For instance, previous systems have focused primarily on the creation of boxes and sealing the boxes once they are filled. Such systems have required the use of multiple separate machines and significant manual labor. By way of example, a typical box forming system includes a converting machine that cuts, scores, and/or creases sheet material to form a box template. Once the template is formed, an operator removes the template from the converting machine and a manufacturer's joint is created in the template. A manufacturer's joint is where two opposing ends of the template are attached to one another. This can be accomplished manually and/or with additional machinery. For instance, an operator can apply glue (e.g., with a glue gun) to one end of the template and can fold the template to join the opposing ends together with the glue therebetween. Alternatively, the operator can at least partially fold the template and insert the template into a gluing machine that applies glue to one end of the template and joins the two opposing ends together. In either case, significant operator involvement is required. Additionally, using a separate gluing machine complicates the system and can significantly increase the size of the overall system.

Once the manufacturer's joint is created, the template can be partially erected and bottom flaps of the template can be folded and secured to form a bottom surface of a box. Again, an operator typically has to erect the box. The bottom flaps can be folded and secured manually by the operator or with the assistance of yet additional machines. Thereafter, an operator transfers the to-be-packaged item(s) into the box and the top flaps are folded and secured.

Accordingly, it would be advantageous to have a packaging machine that can form box templates and fold and secure the templates around the to-be-packaged item(s) without significant manual labor.

BRIEF SUMMARY

Exemplary embodiments of the disclosure relate to systems, methods, and devices for packaging item(s) into boxes. More specifically, exemplary embodiments relate to packaging machines that maintain an arrangement of one or more items and fold and secure a custom box template around the item(s) to package the item(s) in a custom box.

For instance, one embodiment of a packaging machine includes a frame structure and a crowder assembly movably mounted on the frame structure. The crowder assembly can be configured to receive and maintain an arrangement of a stack of one or more items during a packaging process. The crowder assembly can include a first half comprising a sidewall and a second half comprising a sidewall. At least one of the first half and the second half also includes a back wall. Likewise, at least one of the first half and the second half also includes a floor. The sidewall of the second half can be positioned opposite the sidewall of the first half and can be selectively movable towards and away from the sidewall of the first half. The crowder assembly can also include a front wall assembly that has a variable width to enable the front wall to be positioned between the sidewalls of the first and second halves. The front wall assembly can be selectively movable towards the back wall.

According to another embodiment, a system for packaging one or more items includes an order arrangement station where the one or more items can be arranged into a stack and a dimensioning mechanism configured to determine outer dimensions of the stack. The system can also include a converting assembly configured to create a box template that when erected forms a box that is custom sized to the dimensions of the stack. A crowder assembly can be included that is configured to hold and maintain the stack in a desired configuration while the box template is at least partially folded around the stack. Folding mechanism(s) can fold the box template around the stack and a fastening apparatus can apply one or more fasteners to the box template to secure the box template around the stack in the form of a box.

According to another embodiment, a method for packaging one or more items includes arranging the one or more items into a stack with a desired configuration and determining the outer dimensions of the stack. The method also includes creating a box template that when erected forms a box that is custom sized to the dimensions of the stack and depositing the stack in a crowder assembly configured to hold and maintain the stack in the desired configuration while the box template is at least partially folded around the stack. The method further includes folding the box template around the stack and securing the box template around the stack in the form of a box.

DETAILED DESCRIPTION

The embodiments described herein generally relate to systems, methods, and devices for packaging item(s) into boxes. More specifically, the described embodiments relate to machines that maintain an arrangement of one or more items and fold and secure a custom box template around the item(s) to package the item(s) in a custom box.

While the present disclosure will be described in detail with reference to specific configurations, the descriptions are illustrative and are not to be construed as limiting the scope of the present disclosure. Various modifications can be made to the illustrated configurations without departing from the spirit and scope of the invention as defined by the claims. For better understanding, like components have been designated by like reference numbers throughout the various accompanying figures.

As used herein, the term “box template” shall refer to a substantially flat stock of material that can be folded into a box-like shape. A box template may have notches, cutouts, divides, and/or creases that allow the box template to be bent and/or folded into a box. Additionally, a box template may be made of any suitable material, generally known to those skilled in the art. For example, cardboard or corrugated paperboard may be used as the box template material. A suitable material also may have any thickness and weight that would permit it to be bent and/or folded into a box-like shape.

FIG. 1 illustrates an example method or set of process steps 100 for packaging one or more items in a box. The process 100 may be used to package items in a box for shipping or other purposes and may reduce the amount of work or other involvement required of individuals to package the items.

The method 100 begins with an order transfer 102. The order transfer 102 may comprise a variety of steps including receiving an order from a customer, collecting the ordered item(s), and/or transferring or otherwise delivering the ordered item(s) to a packaging station for measurement and/or packaging.

After the order transfer 102, the ordered item(s) may be arranged (step 104). For instance, if the order includes a single item, that item maybe positioned in a desired orientation for packaging. On the other hand, if the order includes multiple items, the items may be arranged in a desired configuration for packaging (referred to hereinafter as a “stack”). For instance, the items may be arranged into a stack that takes up a minimum volume, that positions smaller items on top of larger items, etc. In some embodiments, arranging the item(s) may be done by an operator or by one or more mechanical devices.

Once the item(s) are arranged into a stack, a dimensional scam may be taken of the stack (step 106). For instance, one or more dimensioning mechanisms may be used to determine the outer dimensions of the stack. Example dimensioning mechanisms may include three dimensional cameras or scanners, light curtains, measuring tapes, or the like.

Obtaining the dimensions of the stack can trigger the printing of box template (step 108). For example, the dimensions of the stack may be transferred (automatically or manually) to a machine that creates custom sized box templates. The box template forming machine may then form cuts and/or creases in a stock material (e.g., cardboard or corrugated paperboard) to form a box template custom sized for the stack of items (step 110). The box template can then be transferred to a packaging station (step 112).

While a box template is being formed, the stack of items may be moved to the packaging station (step 114). At the packaging station, the stack of items can be packed, which can include erecting the box template around the stack of items and sealing the box (step 116). In some embodiments, step 116 also includes labeling the box (e.g., applying or printing a shipping label on the box).

FIG. 2 illustrates an example system 120 used in performing process 100. In the illustrated embodiment, items for packaging are delivered to the system 120. The items may be positioned and arranged into a stack on the conveyor 122. The dimensions of the stack may be obtained while the stack is positioned on the conveyor 122, either before the stack enters the packaging machine 124 or once the stack is moved inside of the packaging machine 124. That is, the dimensioning mechanisms used to obtain the dimensions of stack may be positioned outside or inside the packaging machine 124.

In any event, the stack of items is advanced into the packaging machine 124 on conveyor 122. The packaging machine 124 creates a box template custom sized for the stack of items and folds and secures the box template around the stack of items. The packaged stack is then advanced out of the packaging machine 124 on another conveyor 126.

FIGS. 3-25 illustrate exemplary embodiments of internal components of packaging machine 124 that are used to package stacks of items in custom sized boxes. Although specific embodiments of internal components of packaging machine 124 are shown and described, it will be appreciated that the specific implementations are merely exemplary. Variations to the shown and described components may be made without departing from the scope of the present disclosure. Rather, the present disclosure is intended to encompass components that perform the basic functions described herein.

FIG. 3 illustrates conveyor 122 upon which a stack of items is conveyed into the packaging machine 124. The conveyor 122 delivers the stack of items to a crowder assembly 130. As will be described below, the crowder assembly 130 is configured to maintain the stack of items in the configuration created during step 104 described above while a box template is folded and secured around the stack of items.

As can be seen in FIG. 3, the crowder assembly 130 is movably mounted on a frame structure 132 such that the crowder assembly can move (in the direction indicated by the double headed arrow) towards and away from conveyor 122. In the illustrated embodiment, the crowder assembly 130 includes a first half 134, a second half 136, and a front wall assembly 138.

Attention is now directed to FIGS. 4-7 which illustrate the crowder assembly 130 separate from the rest of packaging machine 124. In the illustrated embodiment, the first half 134 and the second half 136 are substantially mirror images of one another. For instance, the first and second halves 134, 136 each include a back wall 140, a floor 142, and a sidewall 144. In some embodiments, the back wall 140 and the floor 142 of the first half 134 are connected together and the back wall 140 and the floor 142 of the second half 136 are connected together.

The sidewalls 144 may move relative to one another and relative to the back wall 140 and the floor 142 of the corresponding half. For instance, a comparison between FIGS. 4 and 5 shows the sidewalls 144 at different positions relative to one another and relative to the back walls 140 and the floors 142. In FIG. 4, the sidewalls 144 are spaced apart so that a stack of items may be delivered into the crowder assembly 130 between the sidewalls 144. Once the stack of items is position within the crowder assembly 130 (e.g., above floors 142 and between sidewalls 144), the sidewalls 144 may be moved towards one another (and relative to back walls 140 and floors 142) and towards the stack disposed therebetween until the sidewalls 144 are positioned against or adjacent to the stack of items.

Once the sidewalls 144 are positioned against or adjacent to the stack of items, the front wall assembly 138 may be lowered between the side walls 144 and moved towards the stack of items. For instance, FIGS. 6 and 7 illustrate a rear perspective view of the crowder assembly 130 with the front wall assembly 138 lowered.

In the illustrated embodiment, the front wall assembly 138 includes a plurality of front wall sections 146 that may be individually lowered to create a front wall for the crowder assembly 130. The number of front wall sections 146 that are lowered may be determined by the distance between the sidewalls 144 (which is determined by the width of the stack of items within the crowder assembly 130). In some embodiments, some of the front wall sections 146 have similar widths while one or more of the front wall sections 146 have a width that is different than the rest of the front wall sections 146. For example, as shown in FIGS. 6 and 7, a center front wall section 146 has a width that is wider than the rest of the front wall sections 146. In some embodiments, the center front wall section 146 has a width of about eight inches while the rest of the front wall sections 146 have a width of about 1 inch each.

Once the proper number of front wall sections 146 are lowered between the sidewalls 144 (e.g., to span the gap between the sidewalls 144), the front wall assembly 138 may be moved towards the back walls 140 until the front wall sections 146 are positioned against or adjacent to the stack of items disposed within the crowder assembly 130. By moving the sidewalls 144 towards one another and the front wall assembly 138 towards the back walls 140, the crowder assembly 130 contains the stack of items therein in the configuration arranged in step 104. As discussed in greater detail below, with the stack contained within the crowder assembly 130 as described, a box template can be folded around the crowder assembly to package the items therein within the packaging template.

It will be noted that while the crowder assembly 130 has been described and illustrated as having two halves that are mirror images, this is only exemplary. For instance, in some embodiments the first half 134 may have a sidewall that remains stationary relative to its corresponding back wall 140 and floor 142. In such an embodiment, the sidewall of the second half may only move towards the stationary sidewall of the first half (even moving over the floor 142 of the first half). Similarly. The front wall sections may also be arranged so that a wider front wall section is positioned closer to the stationary sidewall of the first half. In other words, the crowder assembly may be configured to justify everything to one side thereof, such that the stack of items is positioned towards one side of the crowder assembly rather than being centered therein as in the illustrated embodiment.

Once the stack of items is securely position within the crowder assembly 130 (e.g., positioned on floor(s) 142 and between opposing sidewalls 144, back wall(s) 140, and front wall sections 146), the crowder assembly 130 may move along a frame structure 132 towards a packaging station, as shown in FIG. 8. At the packaging station, a box template 148 may be advanced underneath the crowder assembly 130 and/or the crowder assembly 130 may be advanced over the top of the box template 148.

The box template 148 may be formed or created by the converting assembly that is part of or separate from the packaging machine 124. The converting assembly may form cuts and/or creases in the template material to form box template 148. The cuts and creases may form various panels and flaps of the box template 148 and facilitate folding of the box template 148 around the stack of items.

FIGS. 9-24 illustrate example steps for folding the box template 148 around the stack of items. As shown in FIG. 9, the box template is folded up against the back walls 140 of the crowder assembly 130. With box template 148 positioned below the crowder assembly 130 and box template 148 folded up against the back walls 140, the back walls 140 and floors 142 of the crowder assembly 130 can be withdrawn or retracted away from the stack of items, as shown in FIG. 10. When back walls 140 and floors 142 are withdrawn or retracted, the stack of items is deposited on top of a panel of the box template 148 and the folded portion of the box template 148 replaces the back walls 140, as shown in FIG. 10.

In some embodiments, such as that illustrated in FIG. 10, when back walls 140 and floors 142 are withdrawn or retracted, back walls 140 and floors 142 are rotated away from the stack of items. Rotation of the back walls 140 and floors 142 can provide additional clearance for subsequent steps of folding the packaging template 148 around the stack of items.

FIGS. 11-24 illustrate additional folds being formed in the box template 148 to fold the box template 148 around the stack of items. In particular, various folding mechanisms are used to fold flaps and panels of the box template 148 around the stack of items. The folding mechanisms may take any of a variety of forms. For instance, the folding mechanisms may be arms, levers, or other mechanisms that can be moved relative to the box template 148 and/or relative to which the box template 148 may be moved in order to fold the flaps and/or panels of the box template 148 around the stack of items.

For instance, as can be seen when comparing FIGS. 10 and 11, folding bars 149 can be used to fold flaps of the box template 148 that will at least partially form sidewalls of the resulting box. To fold the panels with the folding bars 149, the folding bars 149 can be moved relative to the box template 148 so as to engage the panels of the box template 148 and fold them towards the stack of items. Additionally, or alternatively, the box template 148 (with the stack of items thereon) can be moved towards the folding bars 149 so as to engage the panels of the box template 148 and fold them towards the stack of items.

Thereafter, as shown in FIG. 12, additional panels of the box template 148 can be folded up to form at least portions of the sidewalls of the resulting box. The additional sidewall panels can be folded up with folding arms 151 (one of which is shown in FIGS. 13-21).

As shown in FIG. 13, after some of the folds are formed the in the box template 148, the first half 134 and the second half 136 of the crowder assembly 130 are moved along the frame structure 132 back towards the conveyor 122 in preparation for receiving another stack of items. Notably, as also shown in FIG. 13, the front wall assembly 138 can remain positioned adjacent to the stack of items even after the first half 134 and the second half 136 of the crowder assembly 130 are moved back towards the conveyor 122. The front wall assembly 138 can remain in place as shown in FIGS. 13 and 14 while additional folds are made to the packaging template 148 to create a front wall from the packaging template 148 to contain the stack of items.

At least portions of the front wall of the box can be formed using folding levers 153, one of which is shown in FIGS. 13-21. In the illustrated embodiment, folding levers 153 are connected to folding arms 151. In some embodiments, one or more actuators can be connected to folding levers 153. Activation of the actuators can cause folding levers 153 to pivot or otherwise move to fold additional panels of the box template 148.

Once a front wall has been at least partially formed with the packaging template 148, as shown in FIG. 15, the front wall sections 146 can be raised and removed from between the stack of items and the front wall of the box partially formed by the box template 148. Thereafter, the front wall assembly 138 can move along frame structure 132 back towards conveyor 122 in preparation for another stack of items.

With the front wall assembly 132 removed, additional folds can be made to the box template 148 as shown in FIGS. 17-24. For instance, as shown in FIG. 17, a portion of the box template 148 can be folded down towards the stack of items to form a top surface of the resulting box. This can be done with one or more stationary or movable folding arms. Additionally, one or more folding arms can fold down the glue tab 150 of the box template 148, as shown in FIG. 18.

Once the box template 148 is folded around the stack of items as shown in FIG. 18, glue can be applied to a glue tab 150 and/or a panel 152 of the box template 148. Thereafter, the panel 152 can be folded towards the glue tab 150 via folding bar 155, as shown in FIG. 19. The glue can secure the panel 152 to the glue tab 150 together. With the panel 152 and the glue tab 150 secured together, a partially formed box formed by the box template 148 is at least partially secured around the stack of items. At this stage, folding arms 151 and folding levers 153 may be withdraw or retracted, as shown in FIG. 20.

The partially formed box (containing the stack of items) can then be advanced via conveyors 154 (or other mechanisms) as shown in FIG. 21-23. As the partially formed box moves along conveyors 154, the partially formed box moves past glue applicators 156 (as shown in FIGS. 22 and 23) on opposing sides thereof (only one glue applicator 156 is shown). The glue applicators 156 apply glue to one or both of panels 158, 160 of the box template 148 as the partially formed box passes thereby.

After glue is applied by the glue applicators 156, panels 160 on opposing or opposite sides of the partially formed box are folded down towards panels 158, as shown in FIG. 24. The panels 160 can be folding down by folding arms 157. The glue applied by glue applicators 156 secures panels 158, 160 together, thereby completing the formation of a box surrounding the stack of items.

While the above described and illustrated example embodiment uses gluing apparatuses and glue to attach various portions of the box template together, it will be understood that this is merely exemplary. In other embodiments, various other types of fastening apparatuses and fasteners can be used. For instance, an adhesive tape may be used to secure the various portions of the box template together. In still other embodiments mechanical fasteners (e.g., staples, clips, clamps, etc.) may be used to secure the various portions of box template together. Each of the foregoing may be considered fasteners and the apparatuses that apply them to the box template may be considered fastening apparatuses.

Once the box is fully formed and secured around the stack of items or in the process thereof, a label may be applied or printed on the box and the box can be conveyed to conveyor 126, wherein it is dispensed from or exits the packaging machine 124.

Attention is now directed to FIGS. 25-28, which illustrate another embodiment of a crowder assembly 200. In many respects, including structural and functional aspects, crowder assembly 200 may be similar or identical to crowder assembly 130 described above. Accordingly, the following discussion will focus on some of the unique aspects of crowder assembly 200, particularly when compared to crowder assembly 130.

In the illustrated embodiment, the crowder assembly 200 includes a pre-crowder 202, a crowder 204, a front wall assembly 206, and back wall assembly 208. As with the crowder assembly 130, the crowder assembly 200 is configured to maintain the stack of items in the configuration created during step 104 described above during a packaging process, including while a box template is folded and secured around the stack of items.

FIGS. 26 and 27 illustrate rear and front perspective views of the pre-crowder 202 and the front wall assembly 206. As best seen in FIG. 26, the pre-crowder 202 includes a first half 210 and a second half 212. Each of the first half 210 and the second half 212 includes a floor 214 and a sidewall 216. The floors 214 can provide a surface on which a stack of to-be-packaged items can be placed. In some embodiments, the floors 214 can be movable (e.g., hinged) to allow for the floors 214 to be moved to provide access deeper into the crowder assembly 200 for maintenance, etc.

Similar to sidewalls 144, sidewalls 216 may move relative to one another and relative to the floors 214 of the corresponding half. The sidewalls 216 may be spaced apart so that a stack of items may be delivered into the pre-crowder 202 between the sidewalls 216. Once the stack of items is position within the pre-crowder 202 (e.g., on floors 214 and between sidewalls 216), the sidewalls 216 may be moved towards one another (and relative to the floors 214) and towards the stack disposed therebetween until the sidewalls 216 are positioned against or adjacent to the stack of items.

Once the sidewalls 216 are positioned against or adjacent to the stack of items, the front wall assembly 206 may be activated to form a front wall adjacent or against the stack of items and between the side walls 216. For instance, as best seen in FIG. 27, portions of the front wall assembly 206 may be moved to form the front wall.

In the illustrated embodiment, the front wall assembly 206 includes a plurality of front wall sections 218 that may be moved horizontally and/or vertically (individually or in various combinations) to create a front wall. The front wall sections 218 may be mounted on one or more tracks 213 that enable the front wall sections 218 to move horizontally. Likewise, the front wall sections 218 may include one or more actuators 215 to facilitate movement (e.g., vertical movement) of one or more plate 217 thereof.

The number of front wall sections 218 that are moved into a wall position may be determined by the distance between the sidewalls 216 (which is determined by the width of the stack of items within the pre-crowder 202). In some embodiments, some of the front wall sections 218 have similar widths while others of the front wall sections 218 may have a width that is different than other front wall sections 218.

In the illustrated embodiment, as best seen in FIG. 27, the front wall assembly 206 may include front wall sections 218a and 218b that can at least partially overlap one another to provide greater variability in the width of the front wall formed with the front wall assembly 206. More specifically, front wall sections 218a and 218b may include plates 217 having a predetermined width and which can at least partially overlap one another. For instance, in some embodiments, the plates 217 of front wall sections 218a and 218b can each be about 8 inches wide. The plates 217 can at least partially overlap one another such that the plates 217 of front wall sections 218a and 218b can form a front wall having a width anywhere from about 8 inches wide to about 15 inches wide (with a 1 inch overlap). In some embodiments, the plates 217 of front wall sections 218a and 218b can always remain at least partially overlapped with one another such that the plates 217 of front wall sections 218a and 218b can form a front wall having a width anywhere from about 8 inches wide to about 15 inches wide (with a 1 inch overlap of the plates 217). In other embodiments, the plates 217 of front wall sections 218a and 218b may not always overlap one another. In such embodiments, the plates 217 thereof may form a front wall having a width anywhere from about 8 inches to about 16 inches.

If a front wall needs to be formed that is wider that that provided by front wall sections 218a and 208b, additional front wall sections 218 can be moved into position adjacent front wall sections 218a and 218b. For instance, if a front wall of about 20 inches needs to be formed, front wall sections 218a and 218b can be moved into place to form about 13 inches of the front wall (by partially overlapping the plates 217 thereof). Additionally, another front wall section 218 (with plate 217 having a width of about 7 inches) can be moved into place adjacent the front wall sections 218a and 218b to form the remainder of the 20 inch wide front wall. Likewise, the plates 217 of the front wall sections 218a and 218b can be moved to overlap more or less and additional front wall sections 218 can be moved into place to form a front wall having substantially any desired width.

While the plates 217 have been described as having specific widths (e.g., 8 inches or 7 inches), it will be appreciated that those dimensions are merely exemplary. In other embodiments, the plates 217 may have widths smaller than 7 inches, between 7 and 8 inches, or larger than 8 inches. Similarly, some of the plates 217 may have different sizes from one another. Furthermore, the amount of overlap between adjacent plates may vary from one embodiment to another. Furthermore, while the illustrated embodiment only shows two plates that overlap one another, it will be appreciated that additional front wall sections 218 may have plates that overlap one another.

Once the front wall is arranged between the side walls 216, the front wall assembly 206 can be moved towards the stack of items positioned within the pre-crowder 202. The front wall can further stabilize the stack of items so the stack of items does not fall over or become disorganized. Additionally, the front wall can move the stack of items from the pre-crowder 202 into the crowder 204. More specifically, the front wall assembly 206 can move (horizontally) towards the crowder 204. Such movement of the front wall assembly 206 can cause the front wall (formed with the front wall sections 218) to push the stack of items from the pre-crowder 202 into the crowder 204.

As can be seen in FIG. 28, the crowder 204 includes a first half 220 and a second half 222. Each of the first half 220 and the second half 222 includes a floor 224 and a sidewall 226. The floors 224 can provide a surface on which the stack of to-be-packaged items can be placed Similar to sidewalls 216, sidewalls 226 may move relative to one another and relative to the floors 224 of the corresponding half. The sidewalls 226 may be spaced apart so that the stack of items may be delivered into the crowder 204 between the sidewalls 226.

In some embodiments, the sidewalls 226 are moved towards one another prior to the stack of items being moved into the crowder 204. For instance, the sidewalls 226 may move towards one another at about the same time the sidewalls 216 of the pre-crowder 202 are moved towards one another. In other embodiments, the sidewalls 226 are moved towards one another after the stack of items has been moved into the crowder 204.

Additionally, the back wall assembly 208 may form a back wall of the crowder 204. The back wall assembly 208 may be substantially similar to the front wall assembly 206 (e.g., movable back wall sections with plates that form a back wall). The back wall assembly 208 may form a back wall at about the same time that the front wall assembly 206 forms the front wall as described above. Alternatively, the back wall assembly 208 may form the back wall while or after the stack of items is moved into the crowder 204.

In any event, once the stack of items is positioned in the crowder 204 with sidewalls 226 and the front and back walls positioned adjacent to or against the stack of items, the stack of items is securely held in the desired arrangement. Thereafter, the crowder 204 and the front and back wall assemblies 206, 208 can move towards a packaging station where the stack of items are packaged within a box. The movement of the crowder 204 and packaging of the stack of items can be similar to that described above in connection with crowder assembly 130 and FIGS. 8-24.

Generally, for instance, the crowder 204 (with the front and back walls) can move the stack of items over the top of a box template. The box template can then be folded around the stack of items to package the items in the box formed with the box template. As the box template is folded around the stack of items, the crowder 204 and the front and back walls can be withdrawn or retracted. By way of example, after the box template is folded as shown in FIG. 9, the back wall (formed by back wall assembly 208) and the floors 224 can be retracted or withdrawn (which will deposit the stack of items on the box template). Thereafter, the sidewalls 226 can be withdrawn or retracted to allow for the box template to be folded to form sidewalls of a box. Similarly, the front wall (formed by front wall assembly 206) can be retracted or withdrawn prior to or after the box template is folded to form a front wall of the box (similar to that shown in FIGS. 14-15). The remainder of the box template can be folded and secured closed as described above.

The above described system 120 and method 100 may include or use box templates having particular configurations. Box template 148 referenced herein is one example box template that may be used with system 120 and method 100. U.S. application Ser. No. 16/435,252, filed Jun. 7, 2019, and entitled BOX TEMPLATE (the “'252 application”), which is incorporated herein by reference in its entirety, relates to one example box template that may be used with the systems and methods described herein. The '252 application describes and illustrates various features of an example box template, as well as an exemplary process for folding and securing the box template in the form of a box with a stack of items therein. The packaging machine 124 described herein can perform the folding and securing steps described in the '252 application to form a completed box. For instance, the folding and securing steps illustrated in FIGS. 9-25 hereof and performed by the packaging machine 124 may be similar or identical to the folding and securing steps described and illustrated in the '252 application.
