[0020] Please refer to Figure 1 The utility model discloses a film roll grouping into a tray conveying and packing line, comprising single roll packaging system 1 for the packaging of single film roll. Specifically, for example, single roll packaging system 1 mainly includes film wrapping device 11 (including hot melting table) and buckling device 12 (including buckling table) arranged in sequence, and also includes a carrying device for carrying film rolls, so that a layer of film is wrapped on the film produced and rolled into a film roll, clamping plates and / or plugs are buckled at both ends of the film roll, and the basic packaging of single film roll is completed. The process and related equipment structure are all prior art.

[0021] The turnover device 2 for standing up the film roll is arranged on the downstream side of single roll packaging system 1, which is also prior art, such as the structure shown in the Chinese utility model with the authorization announcement number CN217200574U. The film roll is in a horizontal state at the film wrapping device 11 and the buckling device 12 in the single roll packaging system 1, and the carrying device can carry and move the film roll between the film wrapping device 11, the buckling device 12 and the turnover device 2. 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.

[0022] The stacking conveying line 3 is arranged on the downstream side of the turnover device 2, and the stacking conveying line 3 is a line or two parallel lines of conveying belts (or conveying machines), and each line of conveying belts can carry a line of trays (each tray corresponds to a group of products). In the illustrated embodiment, the stacking conveying line 3 is two parallel lines of conveying belts, so that two lines of products can be accommodated at the stacking position, and the capacity is large under the premise of facilitating stacking.

[0023] The pallet placing device 31 is arranged on the side of the palletizing conveying line 3, and is used to place the pallet on the palletizing conveying line 3. The pallet placing device 31 is realized by a mechanical arm or a conveyor, and is clear and easy to realize based on the prior art, and thus is not described herein. Optionally, a pallet warehouse 311 for storing the pallet is arranged on the side of the palletizing conveying line 3, and is used by the pallet placing device 31 or facilitates replenishment of the pallet placing device 31.

[0024] The palletizing device 32 is arranged at the palletizing conveying line 3, and is used to move the film roll on the turnover device 2 to the pallet. The palletizing device 32 can also refer to the prior art, for example, the Chinese invention patent with the application publication number CN110759112A, and includes a rack and a mechanical arm capable of inserting and holding one end of the film roll shaft to carry. Alternatively, the palletizing device 32 can adopt a six-axis industrial robot, and the end thereof is an air inflation shaft or other mechanical components capable of inserting and holding one end of the film roll shaft.

[0025] The size of the pallet matches the bottom surface of the several film rolls arranged vertically and adjacently. Specifically, for example, the pallet is square, and the side length of the pallet is an integer multiple, for example, two or three times of the diameter of the bottom surface of the film roll, so that four or nine film rolls are regularly arranged on one pallet. In this way, the packaged single film roll is grouped and arranged in groups of four or nine, and can be matched and fitted during subsequent banding and film winding. In addition, the pallet is preferably wooden, and has the advantages of being light and low in cost. More specifically, the pallet is spliced by wooden boards, so as to facilitate the formation of the required size. In addition, the pallet is fixed with a support in the form of a crossbeam at the bottom, which is helpful for stable placement, and forms a gap at the bottom for the forklift fork to enter and exit.

[0026] A packing conveying line 4 is connected to the downstream side of the stacking conveying line 3, and can carry a row of pallets. A horizontal banding device 41, a top cover placing device 42, a vertical banding device 43 and a horizontal film wrapping device 44 are arranged in sequence in the conveying direction of the packing conveying line 4. The banding device is also called a bundling device, which is a prior art technology for arranging one or more loops of binding tape around the outer side of the product. The top cover placing device 42 is used to place a top cover above a group of film rolls, for example by a mechanical arm or a conveyor, etc. The shape and size of the top cover can be selected to correspond to the pallet. The horizontal film wrapping device 44 is also called a top wrapping film wrapping device, which is a prior art technology for arranging one or more loops of packaging film around the outer side of the product. For example, the horizontal film wrapping device 44 includes a frame with a rotating shaft in the center above the packing conveying line 4 and a transverse rotating arm connected to the rotating shaft, the end of the rotating arm is connected to a vertical lifting arm, the lifting arm is connected to a film wrapping head through a lifting mechanism, the film wrapping head further includes a packaging film roll placing shaft support, an automatic cutting mechanism, etc. The packaging film roll can rotate around the shaft of the placing shaft support, the end of the packaging film is stripped from the packaging film roll, attached to the surface of the product through the automatic cutting mechanism, and then the film wrapping head rotates around the product under the action of the rotating arm and lifts to wrap the packaging film around the product. When the wrapping amount is sufficient, the packaging film is cut off by the automatic cutting mechanism.

[0027] In the present scheme, a plurality of film rolls are stacked on a pallet to form a group, and then each group of products is conveyed by a conveying line. During the conveying process, each group of products is first conveyed and stopped at the horizontal banding device 41, and then the horizontal banding device 41 is used to band the horizontal direction, which can be selected to distribute two or more binding tapes in the height direction to bind the plurality of film rolls together in the horizontal direction, and then continue to be conveyed and stopped at the top cover placing device 42, and then the top cover placing device 42 is used to place a top cover on the top of the plurality of film rolls, and then continue to be conveyed and stopped at the vertical banding device 43, and then the vertical banding device 43 is used to band the vertical direction around the top cover, the film roll and the pallet, which can be selected to distribute two or more binding tapes in the horizontal direction, and finally continue to be conveyed and stopped at the horizontal film wrapping device 44, and then the horizontal film wrapping device 44 is used to wrap the packaging film on the upper edge, side and lower edge of the group of products, and further make the product form a whole and provide another protective effect. It can be understood that preferably four or more groups of products (four or more pallets) are simultaneously conveyed on the packing conveying line during the working process, so that each packing step is performed simultaneously, and each group of products sequentially performs each step during the conveying process along the assembly line. It should be noted that in the above process, the plurality of film rolls are first positioned by horizontal banding through horizontal binding to facilitate subsequent automatic packaging, and the horizontal binding ensures the stability of the position of the plurality of film rolls during the placement of the top cover and the vertical banding. Finally, the horizontally wrapped packaging film further packages the pallet product with the top cover and the horizontal and vertical binding, and the overall structure is stable and the protection effect of the film is better.

[0028] In the preferred embodiment, a labeling device 45 (also referred to as a labeling machine) is arranged on the side of the packing conveying line 4, downstream of the horizontal film winding device 44, so as to label the outer side of the packaging film. Since the film roll is arranged vertically, the bottom area of the product is reduced, and the labeling of the product is easier to view.

[0029] Further, a conveying system 5 is arranged downstream of the packing conveying line 4, so as to convey the packaged product away from the packing production line. Optionally, the conveying system 5 comprises a forklift, which is convenient to operate and flexible to convey. It should be noted that the existing horizontally-stacked film rolls are not suitable for forklift transportation, on the one hand, the film roll is too long to be stably forked, and on the other hand, the forks of the forklift may damage the film. In the present scheme, the bottom of the packaged product is a pallet, so there is no such problem.

[0030] Further, the single-roll packaging system 1 and the stacking conveying line 3 are arranged in a straight line, and the packing conveying line 4 is arranged in a straight line and perpendicular to the stacking conveying line 3. This layout is reasonable, occupies less space while ensuring the distance between the devices, and is particularly suitable for the case where the stacking conveying line has two (or more) rows. That is, the product is distributed in two (or more) rows and multiple rows on the stacking conveying line, and then at the end of the stacking conveying line, the perpendicular conveying line is matched to convey each row of products one by one. In other words, this conveying layout directly realizes the conversion of the stacked products into a single row of products.

[0031] In some embodiments, a front-end conveying line 6 is arranged upstream of the single-roll packaging system 1, for example, perpendicular to the single-roll packaging system 1 and the stacking conveying line 3, and on the same side as the packing conveying line 4. In some embodiments, the front-end conveying line 6 (part of it) is used to convey the film rolls to be packaged. In yet some embodiments, the front-end conveying line 6 is provided with a quality inspection table 61 and / or a manual packaging system 62. The quality inspection table 61 is used to check whether the single film roll to be packaged or after being packaged is qualified. The manual packaging system 62 is used for manual auxiliary packaging work, for example, for products with a small production volume, after being packaged by the film winding device 11 and the buckling device 12, the product is transported by the carrying device to the front-end conveying line 6, conveyed to the manual packaging system 62, and manually packaged. After the packaging is completed, the product is conveyed by a forklift.

[0032] More specifically, on the side of the single-winding packaging system 1 and the palletizing conveying line 3 away from the packing conveying line 4, an electrical box 7 is arranged, which includes electrical boxes of various devices (robots, mechanical arms) and electrical boxes of various conveying lines, and optionally a control console and the like is arranged here. In this preferred layout of the present scheme, the electrical and control parts are centrally arranged, which can make the line structure clear and intuitive, and has a safe distance from the mechanical action range of the equipment and the working range of the forklift, so it is more convenient for control operation, maintenance and other work.

[0033] In summary, the film roll grouping of the present application has a reasonable layout, high efficiency, and can realize the vertical standing, grouping and stacking of the preliminarily packaged film rolls, and then the multiple film rolls in each group are packaged, and then the products in each group are labeled and transported; and during this process, the pallets can be automatically placed on the conveying belt without manual handling, and after the stacking is completed, the pallets can be directly transported by the conveying belt; in addition, since the film roll vertical standing method is adopted, it can be suitable for both short film rolls and long film rolls, facilitating product stacking, improving space utilization, and enabling flexible transportation by forklift.
