TECHNICAL FIELD
[0001] The utility model belongs to product packaging and transportation technical field, specifically relates to a kind of packing line of product in tray. BACKGROUND
[0002] Film products are usually wound into rolls after production, and then need to be packaged to provide protection for the film. The existing packaging system, such as Chinese patent for invention with application publication number CN114313505A, places the film roll horizontally. However, for cases where the film roll is long, for example, horizontal placement can result in low space utilization, and it is inconvenient for stacking and subsequent conveying of the product. In addition, for the case of multiple film rolls stacked on a tray, secondary packaging is required. There is no packing line for tray-formed products with vertically stacked film rolls on the market, and manual assistance is required when using existing packing lines, which needs to improve the degree of automation and packing efficiency. SUMMARY
[0003] The technical problem to be solved by the utility model is to provide a packing line for tray-formed products, to solve the problem that existing solutions are not suitable for packaging tray-formed products with vertically stacked film rolls, and to achieve more automation, higher work efficiency and other technical effects.
[0004] According to the technical scheme of the utility model, the utility model provides a packing line for tray-formed products, which includes a packing conveyor line for conveying tray-formed products. Each tray-formed product includes a tray and multiple film rolls on the tray. The multiple film rolls are vertically stacked and adjacent on the tray. A horizontal taping device, a top cover plate placing device, a vertical taping device and a horizontal film winding device are sequentially arranged in the conveying direction of the packing conveyor line. The packing conveyor line has a conveying system on the downstream side.
[0005] In some embodiments, the size of the tray matches the bottom surface of the vertically stacked and adjacent film rolls.
[0006] In some embodiments, the tray is square, and the side length of the square of the tray is an integer multiple of the diameter of the bottom surface of the film roll.
[0007] In some embodiments, the tray includes a tray top plate, and the tray support portion below the tray top plate has a through avoidance space on the side. The conveying system includes a forklift, and the avoidance space allows the forks of the forklift to extend in.
[0008] In some embodiments, the tray support portion has a strip-shaped tray foot plate below, and the length direction of the tray foot plate is consistent with the conveying direction of the tray on the packing conveyor line.
[0009] In some embodiments, the packaging conveyor line has a pallet guide, which includes two guide plates whose length direction is consistent with the conveying direction of the packaging conveyor line. The two guide plates are arranged in parallel, and the pallet feet slide with the guide plates.
[0010] In some implementations, two guide plates are located on either side of a pallet foot, and the distance between the two guide plates matches the width of the pallet foot.
[0011] In some implementations, the pallet guide is located at one edge of the packing conveyor line.
[0012] In some embodiments, the pallet is square, and the pallet support is a support block located at nine points at the square corners and center of the pallet, so as to form clearance space on all four sides of the pallet.
[0013] In some embodiments, a labeling device is also provided on the side of the packaging conveyor line, located downstream of the horizontal wrapping device.
[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0015] This utility model's pallet packaging line can better package palletized products with vertically stacked film rolls. It achieves the sequential completion of horizontal strapping, top cover placement, vertical strapping, and horizontal film wrapping on the conveyor line, resulting in high automation and packaging efficiency. Firstly, horizontal strapping initially positions multiple film rolls using transverse straps, facilitating subsequent automatic packaging. Specifically, the preceding transverse straps ensure the stability of the film rolls during top cover placement and vertical strapping. Finally, horizontal wrapping further packages the palletized products with top cover and transverse and vertical straps. The overall structure is stable and provides excellent protection for the film. Attached Figure Description

[0020] This utility model provides a packaging line for palletized products, which solves the problem that existing solutions are not conducive to packaging palletized products with vertical film rolls, and achieves more automated and higher work efficiency.
[0021] Please see Figure 1 , Figure 2 This utility model discloses a packaging line for palletized products, including a packaging conveyor line 1 for transporting palletized products. The packaging conveyor line 1 is, for example, a roller conveyor or other type of conveyor. Each palletized product includes a pallet 2 and multiple film rolls 3 located on the pallet 2. The multiple film rolls 3 are stacked vertically and adjacent to each other on the pallet 2. Here, "multiple" means two or more. Generally, the film rolls 3 refer to film rolls that have completed preliminary individual packaging. These film rolls are stacked into palletized products and then further packaged by the packaging line of this utility model. After individual packaging, protective film is generally attached to the sides of the film rolls to avoid quality problems caused by squeezing or sticking between adjacent film rolls 3. In addition, the two ends of the film rolls 3 generally have clamps to avoid quality problems caused by direct squeezing or friction between the ends of the film rolls 3 and the pallet 2. Of course, for film rolls that do not have the above-mentioned quality problems or do not have such quality requirements, it is possible to consider not performing preliminary packaging, directly stacking them, and then packaging them by this utility model.
[0022] Along the conveying direction of the packaging conveyor line 1, a horizontal strapping device 11, a top cover placement device 12, a vertical strapping device 13, and a horizontal film wrapping device 14 are sequentially arranged. The strapping device, also known as a binding device, is existing technology and is used to place one or more loops of strapping around the outside of the product. The top cover placement device 12 is used to place a top cover on top of a set of film rolls, for example, by means of a robotic arm or conveyor. The shape and size of the top cover are generally selected to match the pallet. The horizontal wrapping device 14, also known as a top-wrapping device, is a prior art technology used to wrap one or more layers of packaging film (hereinafter referred to as packaging film) around the outside of a product. Specifically, the horizontal wrapping device 14 includes a frame with a rotating shaft centrally located above the packaging conveyor line 1 and connected to a horizontal rotating arm. A vertical lifting arm is connected to the end of the rotating arm, and the lifting arm is connected to a wrapping head via a lifting mechanism. The wrapping head further includes a packaging film roll placement frame, an automatic cutting mechanism, etc. The packaging film roll can rotate around the shaft of the placement frame. The end of the packaging film roll is peeled off and attached to the product surface by the automatic cutting mechanism. Then, the wrapping head rotates and lifts around the product under the drive of the rotating arm, causing the packaging film to wrap around the product. Once sufficient film is wrapped, the packaging film is cut and separated by the automatic cutting mechanism. This process is repeated step-by-step to complete the automated packaging work, forming a product like... Figure 2The structure shown. A conveying system 4 is provided on the downstream side of the packing conveying line 1 for conveying the finished trayed products away from the packing production line 1.
[0023] Preferably, the size of the tray 2 matches the bottom surface of several film rolls that are vertically and adjacently stacked. Specifically, for example, the tray 2 is square, and the side length of the square of the tray 2 is an integer multiple, such as two or three, of the diameter of the bottom surface of the film roll 3, so that four or nine film rolls 3 are regularly stacked on one tray 2, thus grouping the individual film rolls in groups of four or nine, and matching and fitting during subsequent banding and film winding.
[0024] The main process of film roll packaging in the utility model is that a plurality of vertically stacked film rolls are stacked into a group on a tray, and then each group of products (i.e. "trayed products") is conveyed; the packing conveying line 1 is, for example, a line of conveying belts that can carry a line of trays, realizing automatic and continuous performance of the aforementioned sequential packaging processes such as banding, placing a top cover plate, re-banding, and film winding; specifically, during the conveying process of the packing conveying line 1, each group of trayed products is first conveyed and stopped at the horizontal banding device 11, banded in the horizontal direction, which can generally be selected as two or more bands distributed in the height direction to bind the plurality of film rolls together in the transverse direction (of course, mainly serving as a limiting function and hardly causing extrusion to the film rolls, without damaging the film rolls), then continues to be conveyed and stopped at the top cover plate placing device 12, places a top cover plate on the top of the plurality of film rolls, and then continues to be conveyed and stopped at the vertical banding device 13, banded around the top cover plate, film rolls, and tray in the vertical direction, which can generally be selected as two or more bands distributed in the horizontal direction, and finally continues to be conveyed and stopped at the horizontal film winding device 14, winds packaging film on the upper edge, side surface, and lower edge of the trayed product, further forming an integral whole of the trayed product and providing another protective effect. It can be understood that, preferably, there are four or more groups of trayed products on the packing conveying line during the working process, so that each packing step is performed simultaneously, and the plurality of groups of trayed products sequentially perform each step during the conveying process along the assembly line.
[0025] In the preferred embodiment, a labeling device 15 (also referred to as a labeling machine) is further provided on the side of the packing conveying line 1, and the labeling device 15 is located on the downstream side of the horizontal film winding device 14, so as to label on the outside of the packaging film. Since the film roll is vertically stacked to reduce the bottom area of the product and relatively increase the height, the labeling of the product is also easier to view.
[0026] More specifically, the tray 2 used in the present scheme is, for example, a wooden tray, which is a prior art structure shown in, for example, a Chinese invention patent with application publication number CN115158744A, and also like Figure 2As shown, the tray 2 comprises a tray top plate 21, and a tray support portion 22 below the tray top plate 21, and the tray support portion 22 has a through avoiding space 23 on the side. Further, the conveying system 4 comprises a forklift truck, and the existing tray usually has the avoiding space 23, which can enable the fork of the forklift truck to extend in; the cooperation between the forklift truck and the tray 2 can make the conveying system operation simple and flexible. In addition, the avoiding space 23 can also enable the binding belt to pass through the through avoiding space 23, for example, when the vertical banding is performed, so as to bind the tray top plate 21 of the tray 2, the film roll 3 and the top cover plate together.
[0027] Further, the tray support portion 22 has a strip-shaped tray foot plate 24 below, and the length direction of the tray foot plate 24 is consistent with the conveying direction of the tray 2 on the packaging conveying line 1. Preferably, the packaging conveying line 1 has a tray guide 16, and the tray guide 16 comprises two guide plates, the length direction of the guide plates is consistent with the conveying direction of the packaging conveying line 1, the two guide plates are arranged in parallel, and the tray foot plate 24 is in sliding cooperation with the guide plates.
[0028] More specifically, as shown in Figure 1 the two guide plates are respectively located at the two side positions of one tray foot plate 24, and the spacing between the two guide plates matches the width of one tray foot plate 24. The tray guide 16 is located at one side edge position of the packaging conveying line 1. Figure 1 The thicker vertical line in the figure indicates one guide plate, and the other guide plate is located at the right side edge of the packaging conveying line 1. Both of the two guide plates are fixedly connected with the rack part of the packaging conveying line 1, and do not affect the rotating conveying function of the rollers in the packaging conveying line 1. Thus, the tray foot plate 24 on one side of the tray 2 can be matchedly located in the gap between the two guide plates, and the tray foot plate 24 contacts the conveying mechanism itself (such as the rollers) of the packaging conveying line 1, and the tray foot plate 24 on the other side of the tray 2 also contacts the rollers, so that the tray 2 can be limited during the conveying process, and the packaging and conveying processes are more convenient. The scheme can adopt a conventional tray structure, and the modification of the conveying mechanism is less, simple and low in cost, and thus is more suitable for application.
[0029] Please refer to Figure 2 , the preferred tray 2 of the scheme is slightly different from the prior art scheme. The conventional tray structure only has two avoiding spaces 24 in the front-rear direction; in the scheme, the tray 2 is square, and the tray support portion 22 is a support block located at nine point positions of the square corners and the center of the tray 2, so as to form the avoiding space 23 at the four side positions of the tray 2 (corresponding to the four edges of the square), i.e., to have the avoiding space 23 in the front-rear-left-right direction, so as to be more convenient for banding and forklift truck work.
[0030] It should be noted that for the existing transversely stacked film rolls, for example, when the film roll is too long, it is not suitable to use a forklift, because the forklift must be equipped with a pallet or other part that can cooperate with the forks of the forklift. The longer transverse film roll is not convenient to equip these structures, and it is not possible to be directly transported by the forks or clamps. Even if a larger (longer) pallet is used, there are problems such as inconvenience to stabilize the forklift transportation.
[0031] It should be noted that in the existing transverse placement scheme of the film roll, the side surface of the film roll needs to be prevented from contacting the ground, so the film roll needs to be individually packaged, and the clamp plate is usually a hard, larger than the size of the film roll, square plate structure to provide support. In the utility model scheme, after the film roll 3 is individually packaged, the clamp plate or the part between the clamp plate and the film roll can be selected as a soft material such as pearl wool, to avoid direct contact with the hard material and damage due to pressure after the subsequent film roll is vertically placed. In addition, due to the vertical placement instead of the transverse placement, the clamp plate is preferably square or circular, which is consistent with the size of the film roll, so that the subsequent film roll stacking can be more dense and space-saving.
[0032] As a supplement, the upstream side of the packaging conveying line 1 can be provided with a turnover device for vertically placing the film roll 3, which is a prior art, such as the structure shown in the Chinese utility model patent with the publication number CN217200574U. The film roll is in a transverse state after being individually packaged, then is transported to the turnover device, is turned over and placed vertically, and then is grabbed by the stacking device and moved to the pallet. It can be understood that for the six-axis industrial robot or some modification or combination of structures based on the prior art, it can be possible to directly complete the conversion of the transverse film roll to the vertical and stacking by the stacking device; or it can be possible to package by artificial packaging or other automatic packaging methods, so that the individually packaged film roll does not need to be turned over and is in a vertical state.
[0033] In summary, the palletized product packaging line of the utility model can better realize the packaging of the vertically stacked film roll, and realize the process of horizontal banding, placing the top cover plate, vertical banding, and horizontal film winding in sequence on the conveying line, with high automation degree and packaging efficiency. First, the multiple film rolls are preliminarily positioned by the transverse banding, which is more convenient for the subsequent automatic packaging process. Specifically, during the placement of the top cover plate and the vertical banding, the transverse banding in the previous sequence can ensure the stable position of the multiple film rolls. Finally, the palletized product with the top cover plate and the transverse and vertical banding is further packaged by horizontal winding of the packaging film, and the overall structure after packaging is stable and the protection effect of the film is better.
