Product packaging machine and method

Abstract

A method for wrapping a product to be transported includes advancing a base layer in a downstream direction and placing the product to be wrapped on the base layer. After the product is placed on the substrate layer, an adhesive is deposited on the substrate layer at a location adjacent to the product. A cover layer is then applied over the top and substrate layer of the product. The cover layer is secured to the base layer via an adhesive, and the product is secured to the base layer by securing the cover layer to the base layer upstream and downstream of the product. The base layer is then folded laterally over the cover layer and the product to securely wrap the product to be transported.

Description

Technical Field

[0001] The present disclosure relates to a product packaging system, and more particularly to a machine and method for wrapping products with protective packaging material for shipping. Background Art

[0002] When transporting products from one location to another, the products are typically transported in containers with protective packaging materials. The container may be a carton or a protective envelope. Alternatively, the product may be wrapped in protective packaging material, such as plastic bubble wrap, cardboard, paper, or expanded slit sheet material, or the product may be inserted into an already formed envelope, which is then closed to seal the product inside.

[0003] Alternatively, the product may be placed on a continuous sheet and then the outside edges may be guided around the product to form a tube into which the product may be sealed. The tube of material may then be cut to separate the enclosed product in the tube from the continuous sheet and the ends of the tube sealed. If the sheet is a plastic material, heat may be applied to "shrink" the material to adhere more closely to the shape of the product so that the product will not move relative to the material during shipping. Summary of the invention

[0004] The present disclosure relates to a system and method for wrapping products of different sizes in a protective sheet material layer. A product scanner scans the product to identify the size of the product and adjusts the system and method for products of different sizes. Instead of turning the outside edge of a continuous sheet around the product, the product is placed on a continuous base layer and a continuous cover layer is pulled over both the product and the base layer. The cover layer is secured to the base layer and cut, and the first layer is cut and folded around the product to complete the package. Thus, the product is secured within the raw material layer so that the product does not move relative to the sheet material during transportation. The sheet material is preferably paper, which is a recyclable, reusable and renewable resource.

[0005] A method for wrapping a product to be transported includes placing the product to be wrapped on a base layer. After the product is placed on the base layer, an adhesive is deposited onto the base layer at a location upstream of the product. A cover layer extends over the top of the product and the base layer. The cover layer is secured to the base layer upstream and downstream of the product, thereby securing the product to the base layer through the cover layer. The base layer is then folded over the cover layer and the product.

[0006] An exemplary method for wrapping a product to be shipped includes: placing the product on a base layer; extending a cover layer longitudinally on top of the product; securing the cover layer to the base layer so that the product is secured to the base layer by the cover layer; and after the securing step, folding the outer portions of the base layer widthwise around the product and adhering the outer portions of the base layer together.

[0007] Exemplary embodiments of the method further include one or more of the following steps.

[0008] After the fixing step, cutting the base layer and the cover layer;

[0009] cutting the base layer and the cover layer while securing the cover layer to the base layer;

[0010] A substrate layer is provided from a continuous sheet of stock, a cover layer is provided from a continuous sheet of stock; and an upstream end of a product is detected on the substrate layer.

[0011] The cutting step may include: cutting both the base layer and the covering layer in the same cutting action; cutting the base layer and the covering layer at a position upstream of the product; cutting the base layer and the covering layer along a cutting line, setting the cutting line on the base layer with an adhesive upstream and downstream of the cutting line so that portions of the covering layer and the base layer are fixed together on opposite sides of the cutting line; cutting the base layer and the covering layer upstream of the product.

[0012] The securing step may include applying an adhesive to the substrate layer upstream of the product.

[0013] The step of securing may include applying an adhesive to the base layer and then pressing the cover layer against the adhesive on the base layer.

[0014] The applying step may include identifying an upstream end of the product and applying the adhesive to the substrate layer at a location upstream of the product.

[0015] The inspection step includes inspecting the length dimension of the product.

[0016] The method may comprise repeating the method steps for a sequence of products having at least one different size.

[0017] An exemplary packaging system for wrapping a product to be transported includes: a product conveying component, a sensor, an adhesive applicator, a material feeding component, and a pressing element, wherein the product conveying component is configured to place the product on a base layer; the sensor is used to detect the upstream end of the product on the base layer; the adhesive applicator is configured to deposit adhesive to the base layer at a position upstream of the product based on a signal from the sensor; the material feeding component is configured to apply a covering layer on top of the base layer and the product, and the pressing element is configured to press the covering layer to the base layer so that the adhesive fixes the covering layer to the base layer in a manner that fixes the product to the base layer through the covering layer.

[0018] Exemplary embodiments of the system further include one or more of the following elements:

[0019] A supplying member, used for supplying sheet-shaped raw materials of the base layer and the cover layer;

[0020] a cutting assembly configured to cut in width dimensions of the base layer and the cover layer;

[0021] a folding assembly, the folding assembly being located downstream of the pressing element, the folding assembly being configured to fold an outer portion of the base layer in a width direction around the product and the cover layer;

[0022] an adhesive applicator positioned to apply adhesive to the base layer to secure the folded outer portions together; and

[0023] A conveyor for advancing the substrate layer and the products placed on the substrate layer in a downstream direction past the pressing element.

[0024] Another exemplary method for wrapping a product includes the following steps: (1) supplying sheet-shaped raw materials for a base layer and a covering layer; (2) advancing the base layer and the covering layer in a downstream direction; (3) placing a product on the base layer; (4) extending the covering layer longitudinally over the product and the base layer; (5) securing the covering layer to the base layer upstream and downstream of the product so that the product is secured to the base layer through the covering layer; (6) cutting the covering layer and the base layer to separate the covering layer secured to the base layer from the supply; (7) folding the base layer transversely in the width direction on the covering layer and the product; and (8) securing the transversely folded base layer in an appropriate position on the covering layer and the product.

[0033] refer to Figure 1 and Figure 2 , a packaging system 20 for wrapping one or more products 22 for shipping includes: a supply 24 of sheet stock material, a stock feeding assembly 30, a product conveying assembly 32, a cutting and fixing assembly 34, a folding assembly 36, and a system controller 40. The system controller 42 includes: a processor such as a programmable logic controller (PLC), a memory, one or more inputs and one or more outputs, etc., and is configured to control various operations of the packaging system 20. The packaging system 20 moves the sheet stock from the supply 24 in an upstream to downstream direction (also referred to as the downstream direction 42). The upstream direction is opposite to the downstream direction 42.

[0034] The supply 24 of sheet stock may include a support for a roll 44 of sheet stock or a support for a fan-folded stack 46 of sheet stock, or a combination thereof, such as Figure 250 and a cover layer 52. An exemplary sheet stock for the base layer 50 or the cover layer 52 or both is made of paper, such as kraft paper, etc. Paper is an environmentally responsible choice of sheet stock because paper is biodegradable, recyclable, and composed of a renewable resource.

[0035] The base layer 50 and the cover layer 52 can be provided by corresponding continuous sheet materials. The base layer 50 and the cover layer 52 can be any sheet raw material that can be used to cover and protect the product 22 during transportation. In an exemplary embodiment, the base layer 50 is a paperboard, a multi-layer paper product that provides a certain cushioning resistance and puncture resistance, and the cover layer 52 is a single sheet of paper, which is flexible enough to closely follow the shape of the product 22 being transported, but strong enough to keep the product 22 to the base layer 50. In another embodiment, the base layer and the cover layer are both made of paperboard, such as a heavier paperboard for the base layer and a lighter paperboard for the cover layer. In another embodiment, the base layer and the cover layer are all discrete papers with the same or different basis weights. Alternatively, the base layer and the cover layer can be any other material that protects the product during transportation, which can include but is not limited to paperboard, paper, polyurethane, polymer foam, cork, etc. The base layer, the cover layer, or both can have a solid structure. Alternatively, the base layer, the cover layer, or both can have a perforated structure. In another embodiment, the base layer, the cover layer, or both can be formed by a mesh or mesh material.

[0036] The stock feed assembly 30 advances sheet stock from the supply 24 to the product delivery assembly 32 in a downstream direction 42. Figure 2 As shown, the illustrated stock feed assembly 30 includes at least one pair of powered feed rollers 54 and one or more unpowered guide members 56 that define respective paths for the sheet stock of the base layer 50 and the cover layer 52. The feed rollers 54 and guide members 56 of the stock feed assembly 30 advance both the base layer 50 and the cover layer 52 from the supply 24 to the product delivery assembly 32 in the downstream direction 42.

[0037] As the stock feed assembly 30 advances the substrate in the downstream direction 42, the product conveying assembly 32 places the product to be transported on the substrate 50, and the product 22 then advances in the downstream direction 42 on the substrate 50 through the packaging system 20. The product conveying system 32 generally includes a conveyor 60 to support and advance the product 22 and substrate 50.

[0038] Reference Figure 3, the product has a length dimension L, a width dimension W1, and a height dimension H, the length dimension L being parallel to the downstream direction 42, the width dimension W1 being perpendicular to the length dimension L and parallel to the width dimension W2 of the substrate layer 50, and the height dimension H extending in a direction perpendicular to the width dimension W1 and the length dimension L. The corresponding length and height dimensions of the wrapped product are similar to the length and height dimensions of the product. However, the width dimension W2 of the substrate layer 50 is generally greater than the corresponding width dimension W1 of the product 22, so that the substrate layer 50 extends beyond at least one edge of the product 22 to provide insulation protection for the product 22. The difference between the width dimension W1 of the product 22 and the width dimension W2 of the substrate layer 50, and therefore the amount of the width dimension W2 of the substrate layer 50 that provides such insulation protection, will vary depending on the width dimension W1 of the product 22.

[0039] Briefly refer to Fig.11 , the product delivery assembly 32 may optionally include a product scanner 62 configured to identify the size of the product 22. The product scanner 62 includes at least one sensor for determining the length dimension L of the product 22. The product scanner 62 identifies or measures the length dimension L of the product 22. The sensor may include a barcode scanner, a laser, a camera, or other device for determining one or more dimensions of the product (including at least the length dimension). Additionally or alternatively, a sensor may be provided to detect the upstream edge of the product 22 after it is placed on the base layer 50.

[0040] The system controller 40 processes the sensor signals and outputs signals to the cutting and fixing assembly 34 and the folding assembly 36 to adjust the determined dimensions of the product 22. These adjustments allow the packaging system 20 to accommodate and wrap products of random sizes and shapes. Therefore, it will be apparent from this disclosure that the same operation of the packaging system 20 can be used to wrap a wide range of product sizes and shapes for shipping.

[0041] See now Figure 4-Figure 7 , and returns to the product conveying system 32, the conveyor 60 includes a first conveyor section 64 and a second conveyor section 66 located downstream of the first conveyor section 64. The products 22 are placed on the substrate 50 on the first conveyor section 64, and the first conveyor section 64 advances the substrate 50 and the products 22 toward the second conveyor section 66 in the downstream direction 42. Figure 4 As shown, the cover layer 52 is secured to the base layer 50, and the product 22 is placed on the base layer 50, between the base layer 50 and the cover layer 52, at a location upstream of the cover layer 52 being secured to the base layer 50. As the product 22 and base layer 50 advance in the downstream direction 42 on the first conveyor portion 64, the stock feed assembly 30 directs the cover layer 52 to extend over the product 22.

[0042] The cutting and fixing assembly 34 includes an adhesive applicator 70 that deposits an adhesive (such as, but not limited to, liquid glue, hot glue, or adhesive tape) onto the base layer 50 at a location adjacent the upstream end of the product 22, such as Figure 5 In the illustrated embodiment, the adhesive applicator 70 moves downstream until the positioner 72 engages the upstream end of the product 22 and deposits adhesive on the base layer 50 adjacent to the product 22 but upstream of the product 22. The positioner 72 can also help advance the product 22 faster than the base layer 50 in the downstream direction to push the product 22 against the cover layer 52, where the cover layer has been secured to the base layer 50 downstream of the product 22. Alternatively, an electronic sensor can be provided to detect the upstream end of the product 22, and the system controller 40 can control the adhesive applicator 70 to apply adhesive after the upstream end of the product 22 passes through the adhesive applicator 70.

[0043] like Figure 6 As shown, the cutting and fixing assembly 34 also includes a pressing element 74 and a cutting assembly 76. The pressing element moves vertically to press the cover layer 52 into engagement with the adhesive on the base layer 50, thereby capturing the product 22 between the cover layer 52 and the base layer 50. The pressing element 74 also cooperates with the cutting assembly 76 to cut both the base layer 50 and the cover layer 52, thereby separating the captured product 22 from the continuous base layer 50 and the continuous cover layer 52 extending from the supply member 24. In the illustrated embodiment, the pressing element 74 is generally rectangular in shape, with a recess 90 disposed on the bottom surface of the pressing element 74. The pressing element 74 extends in the width direction across the base layer 50 and can be in a ready position ( ) to be vertically removed from the path of the cover layer 52 and the product 22. Figure 6 ) and the pressing position adjacent to the base layer 50 ( Figure 7 The preparation position is generally based on the height dimension of the largest product, which is predetermined and also determines the path of the covering layer 52.

[0044] As the product 22 advances in the downstream direction 42, the pressing element 74 engages the cover layer 52 and presses the cover layer 52 onto the base layer 50 with the adhesive disposed between the cover layer 52 and the base layer 50 below the pressing element 74. Thus, the cover layer 52 is pressed against the top side of the product 22 and secured to the base layer 50 at the upstream end of the product 22, capturing the product 22 between the cover layer 52 and the base layer 50. The cover layer 52 is thus secured to the base layer 50 upstream and downstream of the product 22, and the product 22 is held to the base layer 50 by the cover layer 50.

[0045] The illustrated cutting assembly 76 cooperates with the pressing element 74 to cut the cover layer 52 and the base layer 50. The cutting assembly 76 includes a cutting element 92, such as a sharp wedge or blade, etc. The cutting element 92 is disposed below the gap between the first conveyor portion 64 and the second conveyor portion 66 and in a ready position ( Figure 4 ) and the cutting element 92 cuts the base layer 50 and the cover layer 52 and extends to the cutting position ( Figure 6 Both the base layer 50 and the cover layer 52 are cut simultaneously by the cutting element 92 during the same cutting step.

[0046] The cutting assembly 76 cuts both the base layer 50 and the cover layer 52 along a cutting line that is defined by the adhesive on the upstream and downstream sides. A first portion of the adhesive is disposed upstream of the cutting line, and a second portion of the adhesive is disposed downstream of the cutting line. Since a portion of the adhesive is disposed upstream and downstream of the cutting line, corresponding portions of the base layer 50 and the cover layer 52 are fixed together on opposite sides of the cutting line. Therefore, when the base layer 50 and the cover layer 52 are cut on the upstream side of the product 22, the cutting assembly 76 fixes the base layer 50 and the cover layer 52 together downstream of the subsequent product to be wrapped.

[0047] Although the illustrated embodiment cuts both the base layer 50 and the cover layer 52 simultaneously, the pressing element 74 secures the cover layer 52 to the base layer 50 via an adhesive, as shown. Alternatively, the cutting assembly 76 may operate independently of the pressing element 74. Once the cover layer 52 is secured to the base layer 50 and both the base layer 50 and the cover layer 52 are cut, the pressing element 74 and the cutting element 92 return to their respective ready positions, as shown. Figure 7 shown.

[0048] After cutting the base layer 50 and the cover layer 52, the product 22 continues to advance in the downstream direction 42 on the second conveyor portion 66 to the folding assembly 36. Figure 2 As shown, the folding assembly 36 folds the outer portion of the base layer 50 in the width direction over the cover layer 52 and the product 22. First, the outer portion of the base layer 50 is folded upright at a fold line that is approximately spaced apart from the width dimension W1 of the product 22, and then the first side of the base layer 50 is folded on top of the product 22. Adhesive is applied to the base layer 50, and the second side of the base layer 50 is folded on top of the product 22 and secured to the first side of the base layer 50, completing the wrapping process. The folding assembly 36 may also include a mechanism for applying a shipping label or a printer for printing a label, and the wrapped product is ready for shipping.

[0049] As described above, an advantage of the packaging system 20 is that it adjusts to accommodate different product sizes and shapes. Figures 8A-10C Now see Fig. 8A , Fig.9A and Fig. 10A , three different sized products 22, 26, 28 are shown in a top view placed on a base layer 50, wherein a cover layer 52 covers the products 22, 26, 28 and the base layer 50 and is secured to the base layer 50 upstream and downstream of the products 22, 26, 28. In these examples, the base layer 50 and the cover layer 52 have the same width dimension, and the wrapped products 22, 26, 28 each have a different length dimension L and width dimension W1. The cross-sectional side view is in the corresponding Figure 8B , Fig. 9B and Fig. 10B , which shows how the cover layer 52 holds products 22 , 26 , 28 having different length dimensions L and different height dimensions H to the base layer 50 . Figure 8C , Fig. 9C and Fig. 10C A front view of the wrapped products is shown, showing different sizes that closely correspond to the width dimension W1 and height dimension H of each product 22 , 26 , 28 .

[0050] Reference Figure 1 The packaging system 20 depicted in FIG. 1 describes a corresponding method for wrapping a product 22 to be shipped. However, the method for packaging a product 22 to be shipped may use a structure different from that of the packaging system 20. Figure 1 The product packaging system shown is completed by the product packaging system.

[0051] A method for wrapping a product 22 to be transported includes advancing a base layer 50 in a downstream direction 42 on a product delivery assembly 32, such as a conveyor 60, etc., such as from a pair of powered feed rollers 54 in a stock feed assembly 30. The method includes placing at least one product 22 on the base layer 50, and advancing the product 22 in the downstream direction 42 on the base layer 50 on a first conveyor portion 64. The method includes identifying or detecting a length dimension L or an upstream end of the at least one product 22. The method includes applying an adhesive to the base layer 50 upstream of the product 22, such as with an adhesive applicator 70. The method also includes placing a cover layer 52 over the product 22 and the base layer 50, and after applying the adhesive to the base layer 50, pressing the cover layer 52 against the adhesive on the base layer 50 to secure the cover layer 52 and the product 22 to the base layer 52.

[0052] The method also includes cutting the base layer 50 and the cover layer 52 along the cutting line with an adhesive upstream and downstream of the cutting line. The cutting step can be performed simultaneously with the pressing step. Alternatively, the pressing step can be performed before the cutting step. Finally, the method includes folding the outer portion of the base layer 50 around the product 22 and the cover layer 52 in the width direction, and fixing the outer portions together. The folding step may include: folding a first outer portion of the base layer 50 around the product 22, applying an adhesive, and then folding a second outer portion of the base layer 50 around the opposite side of the product 22, and fixing the second outer portion to the first outer portion. At this point, the product 22 is wrapped and ready for transportation.

[0053] Fig.11 1 shows an alternative embodiment of a packaging system 100. In this packaging system 100, the base layer 50 and the cover layer 52 are cut to the desired length, and the cover layer 52 is fixed to the base layer 50. In other words, the cutting and fixing assembly 34 is upstream of the product conveying assembly 32. The product conveying assembly 32 places the product 22 on top of both the cover layer 52 and the base layer 50. And the product scanner 62 described previously detects the product size that the system controller 40 uses to control the cutting assembly 76.

[0054] The folding assembly 36 then longitudinally folds the upstream and downstream ends of the cover layer 52 around the product 22 and secures the upstream and downstream ends of the cover layer 52 on top of the product 22. The folding assembly 36 then folds the outer portion of the base layer 50 in the width direction around the product 22 and the cover layer 52, similar to the folding assembly 36 in the previous embodiment.

[0055] Fig.12 The manner in which such a packaging system 100 accommodates different product sizes is shown in FIG.

[0056] Thus, in summary, the packaging method described herein for wrapping a product 22 to be transported includes advancing a base layer 50 in a downstream direction 42, and placing a product 22 for wrapping on the base layer 50. After the product 22 is placed on the base layer 50, an adhesive is deposited onto the base layer 50 at a location adjacent to the upstream end of the product 22. The cover layer 52 then extends over the top of the product 22 and the base layer 50. The method includes securing the cover layer 52 to the base layer 50, thereby securing the product 22 to the base layer 50 by securing the cover layer 52 to the base layer 50 upstream and downstream of the product 22. The base layer 50 is then folded transversely in the width direction over both the cover layer 52 and the product 22 to securely wrap the product 22 to be transported.
