DETAILED DESCRIPTION

[0021] The utility model provides a kind of film roll grouping and stacking conveying system, solve the problem that existing scheme cannot adapt to packaging of various film roll products and still need manual stacking, transport tray and product, realize that film roll is grouped and stacked in vertical mode, more convenient to stack, transport etc., and more automated, higher work efficiency.

[0022] Please refer to Figure 1 、 Figure 2The film roll grouping and stacking conveying system of the utility model, including single roll packaging system 1 for packaging single film roll, single roll packaging system 1 is located at the upstream side of the overall structure of packing production line.Single roll packaging system 1 for example mainly includes the film wrapping device 11 (including hot melting platform) and the buckling device 12 (including buckling platform) that are sequentially arranged, and also includes a carrying device for carrying film roll.In the product production process, first of all, film roll is formed by film production and winding equipment, then the film roll is conveyed to single roll packaging system 1, a layer of film is wrapped on the film roll, clamping plate and / or plug and the like are buckled at both ends of the film roll, so that the basic packaging of single film roll is completed, wherein the carrying device can carry and move the film roll between the film wrapping device 11 and the buckling device 12 (and the turnover device 21), for example, the carrying device includes a rack and a mechanical arm arranged on the rack, the mechanical arm can insert and hold the both ends of the film roll core shaft, and then carry.This process and related equipment structure and the like can adopt the prior art.

[0023] In the preferred embodiment, the clamping plate or the part between the clamping plate and the film roll is made of soft material such as pearl wool, so as to avoid damage to the film roll due to direct contact with hard material when the film roll is vertically placed; and since the film roll is vertically placed instead of horizontally placed, the clamping plate is preferably square or circular and consistent with the size of the film roll, so that the subsequent film roll stacking can be more dense and space-saving; in the existing horizontal placement scheme, the film roll side surface needs to avoid contacting the ground, so the clamping plate is usually hard, larger than the size of the film roll and square plate structure, so as to provide support.

[0024] The stacking device 22 and the stacking area are arranged on the downstream side of the single roll packaging system 1, the stacking area is distributed with a plurality of independent tray carrying conveying devices 31, the tray carrying conveying device 31 is fixedly arranged or movably arranged, and the upper surface of the tray carrying conveying device 31 is provided with a tray carrying conveyor (for example, a roller conveyor structure is adopted). The tray transfer device 32 is also included, and the tray transfer device 32 can place the tray on the tray carrying conveying device 31. One tray carrying conveying device 31 corresponds to one tray, in other words, the size of the tray carrying conveying device 31 matches the size of the tray, and after the empty tray is placed on the tray carrying conveying device 31, the tray is carried and conveyed by the tray carrying conveying device 31 until the tray is stacked with film rolls and conveyed out of the tray carrying conveying device 31.

[0025] The palletizing device 22 can stack the film roll packaged by the single-roll packaging system 1 in an upright state on the pallet on the pallet carrying conveyor 31. The palletizing device 22 can refer to the prior art, such as the structure shown in the Chinese invention patent with application publication number CN110759112A, including a rack and a mechanical arm that can insert and hold one end of the film roll core shaft to move on the rack to achieve carrying; or the palletizing device 22 can use a six-axis industrial robot, the end of which is an air inflation shaft or other mechanical components that can insert and hold one end of the film roll core shaft.

[0026] For the foregoing single-roll packaging system 1, optionally, there is a turnover device 21 on the downstream side of the single-roll packaging system 1 for standing up the film roll, which is the prior art, such as the structure shown in the Chinese utility model patent with authorization announcement number CN217200574U. The film roll is in a horizontal state at the film wrapping device 11 and the clamping device 12 in the single-roll packaging system 1, and after clamping is completed, the film roll is carried to the turnover device 21, is turned up, and the turnover device 21 can be rotated in the vertical direction as the axis to make the standing film roll leave the carrying device range, making it more convenient for the palletizing device 22 to grab. It can be understood that for the palletizing device 22 using a six-axis industrial robot or some modifications or combinations of structures based on the foregoing, it can be possible to directly complete the work of turning the horizontal film roll to the vertical and stacking by only the palletizing device 22; or the single-roll packaging system 1 can be packaged by manual packaging or other automatic packaging methods without the need for turning to be in an upright state.

[0027] The size of the pallet matches the bottom surface of the several film rolls stacked adjacent to each other in an upright state; specifically, for example, the pallet is square, and the side length of the pallet is an integer multiple, such as two or three times, of the diameter of the bottom surface of the film roll, so that four or nine film rolls are regularly stacked on one pallet, so that the packaged single film roll is grouped and stacked in groups of four or nine, and can be matched and fitted when subsequent banding and film winding.

[0028] There is a packaging conveyor line 4 on the downstream side of the stacking area for secondary packaging, for example, a horizontal banding device, a top cover plate placing device, a vertical banding device, and a horizontal film winding device are sequentially arranged in the conveying direction of the packaging conveyor line 4. There is a conveying system 5 on the downstream side of the packaging conveyor line 4 for conveying the packaged products away from the packaging production line.

[0029] The tray placing and conveying in the scheme is more automatic and efficient compared with the prior art; the existing scheme generally directly places the tray on the ground by manual mode, and after the stacking of all the film rolls is completed, the tray and the film rolls are transferred to the secondary packaging production line. In some optional embodiments of the utility model, the tray transfer device 32 is the tray placing device, which is realized by a mechanical arm or a conveyor and the like, and a plurality of to-be-used trays are stored in the tray placing device or beside the device. In the preferred embodiments, the tray storage device 33 is further included, the tray storage device 33 can store a plurality of trays, and can further have a mechanical arm or a conveyor and the like for outputting the trays; the upper surface of the tray transfer device 32 has a tray transfer conveyor; the trays can be conveyed in sequence through the tray storage device 33, the tray transfer conveyor of the tray transfer device 32 and the tray carrying conveyor of the tray carrying conveying device 31 and stopped on the tray carrying conveying device 31, so that the automatic placing of the trays is completed by cooperation of the plurality of components.

[0030] The tray transfer device 32 and / or the tray storage device 33 are preferably movably arranged. For example, the tray transfer device 32 and the tray storage device 33 are both movable, for example, have controllable moving trolleys at the bottom, so that the tray transfer process from the tray storage device 33 to the tray transfer device 32 can be completed at any required position, and then the tray transfer device 32 can complete the tray transfer process from the tray transfer device 32 to the tray carrying conveying device 31 at any required position (beside the tray carrying conveying device 31 where the tray is to be placed).

[0031] More specifically, for example, in a feasible embodiment of the utility model, the tray carrying conveying device 31 is fixedly arranged and the position cannot be moved, and only the tray carrying conveyor thereon can perform the conveying work (only in the tray transfer process). In this embodiment, the tray transfer device 32 needs to be movable to each tray carrying conveying device 31 to place the empty tray, and the tray transfer device 32 is then moved to the front end of the packaging conveying line 4 and the tray product after the film roll is full is transferred to the packaging conveying line 4.

[0032] In another feasible embodiment of the utility model, the tray carrying conveyor 31 is movably arranged, for example, it has controllable movable trolleys (such as AGV trolleys) at the bottom, and the tray carrying conveyor can move the tray on it (only during the transfer process of the tray, this conveying work is carried out), and the position of the tray carrying conveyor 31 as a whole can also be moved. In this embodiment, the tray transfer device 32 can be fixed in position, and the tray carrying conveyor 31 is actively moved to the tray transfer device 32 to receive a tray, and then moved to the required position of the stacking area to receive the film roll; of course, the tray transfer device 32 can also be movable as described above, so that the working mode is more flexible. In addition, in this embodiment, the tray carrying conveyor 31 can be directly moved to the front end of the packaging conveying line 4 and the tray product is transferred to the packaging conveying line 4.

[0033] As a supplement, in the preferred embodiment, the tray carrying conveyor 31, the tray transfer device 32 and the tray storage device 33 are movably arranged; in other optional embodiments, one or more of the three types of devices can not be movable, and the required functions can also be achieved, and actual design can be flexible, for example, there are two tray transfer devices 32, one of which is movable and the other is not movable, and the like.

[0034] More specifically, as shown in Figure 1 , Figure 2 , the stacking area is rectangular, and the stacking area can accommodate two rows of tray carrying conveyors 31 (two horizontal rows in the figure, each row has multiple, arranged regularly), tray transfer rails 34 and tray transfer devices 32 are arranged on both sides (or outer sides, the upper and lower sides in the figure) of the stacking area, and the tray transfer devices 32 are movably arranged on the tray transfer rails 34. The length direction of the tray transfer rails 34 is consistent with the length direction of the two rows of tray carrying conveyors 31 (horizontal in the figure), and the conveying direction of the tray carrying conveyor of the tray carrying conveyor 31 and the conveying direction of the tray transfer conveyor of the tray transfer device 32 are perpendicular to the length direction of the two rows of tray carrying conveyors 31 (vertical in the figure). It is worth noting that the movable direction of the tray transfer device 32 and the conveying direction of the tray transfer conveyor thereon are perpendicular, and similarly, the main moving direction of the tray carrying conveyor 31 in the stacking area (if movable) and the conveying direction of the tray carrying conveyor thereon are perpendicular. Thus, it has a relatively simplified structure and high conveying efficiency.

[0035] In addition, as shown in Figure 2As shown by the dotted line portion on the tray transfer track 34 on the upstream side (upper side in the drawing) of the packing conveying line 4, the tray transfer device 32 between the stacking area and the packing conveying line 4 can also be used to realize the conveying connection process of the tray from the tray carrying conveying device 31 to the packing conveying line 4. The tray carrying conveying device 31 can be moved (transversely in the drawing) in the stacking area only, and after being moved to the temporary storage area 35 shown by the dotted line frame in the drawing, the connection is realized through the tray transfer device 32, and the tray carrying conveying device 31 in the upper row in the drawing can form a continuous conveying path with the tray carrying conveyor of the tray carrying conveying device 31 in the lower row, and complete the conveying work of the stacked products to the packing conveying line 4.

[0036] Further, the single-roll packaging system 1 and the stacking area are arranged in a straight line (transversely in the drawing), the packing conveying line 4 is arranged in a straight line (vertically in the drawing), and the packing conveying line 4 is perpendicular to the stacking area. This layout is reasonable and occupies a small area while ensuring the spacing between the various packaging equipment. Preferably, the stacking area has a temporary storage area 35 (shown by the dotted line frame in the middle) at the end, which can be used to temporarily park the stacked products (carried on the movable tray carrying conveying device 31 or other such trolley device) for subsequent secondary packaging. In addition, products outside the packing production line can also be conveyed to the temporary storage area 35 for packaging, that is, the queue, order, etc. of the packaging work can be flexibly adjusted according to the actual situation. Figure 2

[0037] ​The main process of the film roll packaging is that a plurality of vertical film rolls are stacked into a group on a tray, and then each group of products (referred to as "tray product" herein) is transported; the packaging conveying line 4 is, for example, a line of conveying belts, capable of carrying a line of trays, and realizing automatic and continuous packaging process, such as the aforementioned banding, placing a top cover plate, re-banding, film winding and the like; for example, during the conveying process of the packaging conveying line 4, each group of tray products is first transported and stopped at the horizontal banding device, and is banded in the horizontal direction, which can be selected as two or more binding belts distributed in the height direction, so as to bind the plurality of film rolls together in the transverse direction (of course, mainly only for limiting the position, and the film roll will not be damaged due to being pressed), and then continue to be transported and stopped at the top cover plate placing device, and a top cover plate is placed on the top of the plurality of film rolls, and then continue to be transported and stopped at the vertical banding device, and the top cover plate, the film roll and the tray are banded in the vertical direction, which can be selected as two or more binding belts distributed in the horizontal direction, and finally continue to be transported and stopped at the horizontal film winding device, and the packaging film is wound on the upper edge, the side surface and the lower edge of the tray product, so as to further form an integral whole and provide another protective effect. It can be understood that preferably, there are four or more groups of tray products on the packaging conveying line during the working process, so that each packaging step is performed simultaneously, and the plurality of groups of tray products sequentially perform each step during the conveying process along the assembly line.

[0038] In the preferred embodiment, a labeling device 45 (also referred to as a labeling machine) is further arranged on the side of the packaging conveying line 4, and the labeling device 45 is located on the downstream side of the horizontal film winding device (i.e. the downstream side of the packaging conveying line 4), so as to label the outer side of the product after the secondary packaging is completed. Since the film roll is arranged vertically to reduce the bottom area of the product and relatively increase the height, the labeling of the product is also easier to view.

[0039] More specifically, the tray used in the present scheme is a wooden tray, which is a prior art, such as the structure shown in the Chinese invention patent with the application publication number CN115158744A. For example Figure 3 As shown (the preferred structure is shown, which is slightly different from the tray of the prior art), the tray 80 includes a tray top plate 803, and the tray top plate 803 has a tray support part 802 below it, the tray support part 802 has a through avoiding space 804 on the side, and the tray support part 802 has a strip-shaped tray side foot plate 801 below it. The current conventional wooden tray all has this structure, wherein the avoiding space 804 can cooperate with a forklift and / or some packaging device (for example, during vertical banding, the binding belt passes through the through avoiding space 804 to bind the tray top plate 803 of the tray 80, the film roll and the top cover plate together).

[0040] In this solution, specifically, the pallet is placed in the packaging production line such that the length direction of the pallet side foot plate 801 is consistent with the pallet conveying direction. The pallet conveying direction refers to the direction in which the pallet is conveyed by the conveyor and packaging conveyor line (such as a roller conveyor), excluding the direction in which the pallet-bearing conveyor device 31, pallet transfer device 32, and pallet storage device 33 carry the pallet for overall device movement. Furthermore, pallet guides 46 (preferably all three have pallet guides 46) are provided on the packaging conveyor line 4, the pallet-bearing conveyor device 31, and / or the pallet transfer device 32. The pallet guide 46 includes two guide plates, such as... Figure 2 As shown, the pallet guide 46 can optionally be installed on only one side of the conveying mechanism (such as a roller conveyor). The thicker vertical line indicated in the figure represents one of the guide plates, and the other guide plate is located on the right edge of the conveying mechanism. Both guide plates are fixedly connected to the frame of the conveying mechanism and do not affect the rotational conveying function of the rollers in the conveying mechanism. The length direction of the guide plates is consistent with the pallet conveying direction, and the two guide plates are arranged in parallel. The distance between the two guide plates matches the width of the pallet side foot plate 801. Thus, when the pallet 80 is placed, the pallet side foot plate 801 on one side of the pallet 80 is matched and located in the gap between the two guide plates. The pallet side foot plate 801 contacts the conveying mechanism itself (e.g., the rollers), and the foot plate on the other side of the pallet 80 also contacts the rollers, thereby limiting the position of the pallet 80 during the conveying process and facilitating various packaging and conveying processes. This solution can use a conventional pallet structure and requires less and simpler modifications to the conveying mechanism, resulting in lower costs and making it more suitable for application.

[0041] Furthermore, the pallet preferred in this solution differs slightly from existing technologies. Preferably, it features four through-spaces 804 in the front, back, left, and right directions to facilitate strapping and forklift operation. More specifically, while existing pallet structures have a beam-like support structure, this solution preferably uses nine wooden blocks 802 located at the corners and center of a square, thus ensuring four-sided clearance space 804. Correspondingly, the pallet top plate 803 is a single, integral board to guarantee structural strength. Additionally, the three central wooden blocks are either higher or have footboards, ensuring that all wooden blocks (pallet support 802) are in contact with the ground or conveyor mechanism, preventing them from being suspended and guaranteeing support. Further... Figure 3 The right-side tray foot plate 801 of the tray shown is located in the gap between the two aforementioned guide plates; and, Figure 3 The pallet shown has discontinuous side feet 801 on the front and rear sides, with a break at the clearance space 804, which facilitates the vertical strapping process.

[0042] Further optionally, the conveying system 5 comprises a forklift, which is convenient to operate and flexible to transport.

[0043] In summary, the film roll grouping and stacking conveying system can realize vertical standing and grouping and stacking of the film rolls after individual packaging, and the pallets can be automatically placed and conveyed by the conveying mechanism, each pallet is responsible by an independent pallet bearing and conveying device, which has high flexibility and accuracy while having high automation and mechanization; the multiple film rolls of each pallet are further packaged, and each pallet product can be labeled and transported; when the pallet product is packaged, the process of horizontal banding, placing a top cover plate, vertical banding and horizontal film winding is sequentially completed on the conveying line, which has high automation and packaging efficiency; the multiple film rolls are initially positioned by horizontal banding, which is more convenient for subsequent automatic packaging process, and the horizontal banding can ensure the position stability of the multiple film rolls when the top cover plate is placed and vertical banding is performed; finally, the pallet product with the top cover plate and horizontal and vertical banding is further packaged by horizontal winding of the packaging film, which has stable overall structure and good protection effect on the film; the film roll vertical standing method can be applied to both short film rolls and long film rolls, and has reasonable layout, high work efficiency, convenient product stacking, high space utilization and flexible forklift transportation.
