[0002] After production, easy-open cans need to be packaged and stacked for transport to the next site. Generally, a certain number of cans are first stacked into circular strips, then covered with packaging material to form easily movable canister strips. These strips are transported via a conveyor line, and then a robotic arm removes them from the conveyor line and places them on pallets for stacking. During stacking, the canister strips are arranged layer by layer on the pallet, and the pallet needs to be raised and lowered accordingly as the stacking height changes.

[0003] In existing technologies, many pallet lifts are driven by scissor lifts. These scissor lifts use hydraulic cylinders for driving, which can make the pallet lifting height less precise. This makes it difficult for the robotic arm to accurately place the easy-open lid strips on the pallet, thus reducing the accuracy of stacking. Utility Model Content

[0024] Reference Figure 1-4 A lifting device for easy-open lid pallets includes a chassis frame 10, lifting modules 20, a drive module 30, and a film transfer mechanism 40. Multiple lifting modules 20 are arranged around the chassis frame 10. Each lifting module 20 includes a first guide post 21, a first transmission wheel 22, and a first transmission bar 23. The first guide post 21 is vertically arranged, and two first transmission wheels 22 are arranged vertically, with teeth on their outer sides. The first transmission bar 23 is wound around the two first transmission wheels 22 and meshes with them. The chassis frame 10 is slidably connected to each first guide post 21, and fixedly connected to each first transmission bar 23. The drive module 30 includes a first motor 31 and a synchronous transmission assembly 32. The first motor 31 is connected to each lifting module 20 via the synchronous transmission assembly 32. The film transfer mechanism 40 is located above the chassis frame 10.

[0025] During operation, the tray 62 is placed on the chassis frame 10. A robotic arm picks up the easy-open cover strips 61 and stacks them on the tray 62. After one layer is stacked, the first motor 31 drives each lifting module 20 to move synchronously through the synchronous transmission assembly 32 to lower the chassis frame 10 and the tray 62 to a fixed height. Then, the robotic arm continues to pick up the easy-open cover strips 61 and stack the next layer on the tray 62. The film transfer mechanism 40 is used to wrap the easy-open cover strips 61 with adhesive film in an S-shape layer by layer.

[0026] As described above, the first motor 31 drives each lifting module 20 to move synchronously through the synchronous transmission component 32, and the first transmission wheel 22 meshes with the first transmission bar 23 to balance the lifting chassis frame 10, so that the pallet 62 on the chassis frame 10 can be accurately lifted and lowered to the designated position, so that the robot can accurately place the easy-open cover strip 61 on the pallet 62, improving the stacking accuracy; the chassis frame 10 is also slidably connected to multiple first guide columns 21, which can make the chassis frame 10 and the pallet 62 rise and fall smoothly without shaking.

[0027] In this embodiment, the first transmission wheel 22 is configured as a sprocket and the first transmission bar 23 is configured as a chain, so as to have a strong load-bearing capacity.

[0028] In some embodiments, the first transmission wheel 22 may also be configured as a synchronous belt pulley, and the first transmission bar 23 may be configured as a synchronous belt bar.

[0029] In this embodiment, four lifting modules 20 are arranged in a rectangular pattern, that is, the lifting modules 20 are located at the four corners of the rectangular chassis frame 10, which allows the four corners of the chassis frame 10 to be raised and lowered simultaneously, and can be raised and lowered quickly and accurately to the specified height, and the raising and lowering is smooth.

[0030] In this embodiment, the synchronous transmission assembly 32 includes a steering gear 321, a first transmission shaft 322, and a second transmission shaft 323. Both the first transmission shaft 322 and the second transmission shaft 323 are arranged laterally. Two first transmission shafts 322 are provided and arranged parallel to each other. One first transmission shaft 322 is fixedly inserted through the first transmission wheel 22 located at the top of two lifting modules 20, and the other first transmission shaft 322 is fixedly inserted through the first transmission wheel 22 located at the top of the other two lifting modules 20. The ends of both first transmission shafts 322 are connected to the steering gear 321, and the two steering gears 321 are connected to the second transmission shaft 323. One of the steering gears 321 is connected to the first motor 31. The steering gear 321 includes a housing and two mounting shafts. The two mounting shafts are arranged vertically and rotatably mounted on the housing. Both mounting shafts are fixedly fitted with bevel gears, which mesh with each other. This structure enables 90° transmission steering. One of the steering gears 321 has two mounting shafts that are respectively connected to the first drive shaft 322 and the second drive shaft 323; one of the mounting shafts of the other steering gear 321 is connected to the second drive shaft 323, and the other mounting shaft of the steering gear 321 is connected to the first drive shaft 322 and the second motor 45.

[0031] In some embodiments, the first drive shaft 322 or the second drive shaft 323 may be connected to the first motor 31 for transmission.

[0032] In this embodiment, the film transfer mechanism 40 includes a second guide post 41, a film transfer frame 42, a second transmission wheel 43, and a second transmission bar 44. The second guide post 41 consists of two parallel lines arranged laterally. Each end of the film transfer frame 42 is slidably connected to one of the second guide posts 41. Two second transmission wheels 43 are arranged laterally at intervals, with one wheel connected to a second motor 45. The second transmission bar 44 is wound around the two second transmission wheels 43 and is fixedly connected to the film transfer frame 42. The film transfer frame 42 includes a support base 421 and two film transfer rods 422 located at the bottom of the support base 421. The film transfer rods 422 are two parallel lines. The central shaft of the film roll is rotatably placed on the support base 421, and the released film is located between the two film transfer rods 422. The second transmission bar 44 is a synchronous belt or chain.

[0033] During operation, the adhesive film is first released, and after the easy-open cover strip 61 is stacked on the adhesive film, the second motor 45 drives the film transfer frame 42 to move laterally through the second transmission bar 44 to continue releasing the adhesive film and laying another layer on the easy-open cover strip 61. Then, another layer of easy-open cover strip 61 is laid on the adhesive film, and the film transfer frame 42 moves in the opposite direction to lay another layer on the easy-open cover strip 61, so that the easy-open cover strip 61 can be wrapped with adhesive film in an S-shape layer by layer.

[0034] In some embodiments, the film transfer frame 42 can also be driven to slide along the second guide post 41 by a linear module driven by a lead screw or rack.

[0035] In this patent embodiment, the easy-open lid stacking tray lifting device also includes a limiting mechanism 50 located above the chassis frame 10. The limiting mechanism 50 is configured as four and is distributed around the tray 62. The limiting mechanism 50 can push the easy-open lid strip 61 to keep it neatly stacked.

[0036] Specifically, the limiting mechanism 50 includes a pusher frame 51, a pusher plate 52, and a cylinder 53. The pusher plate 52 has a third guide post 54 that is slidably connected to the pusher frame 51. The second guide post 41 and the cylinder 53 are both arranged laterally, and the cylinder 53 is connected to the pusher frame 51 and the pusher plate 52 respectively. When the easy-open cover strips 61 are stacked, the cylinder 53 drives the pusher plate 52 to move toward the easy-open cover strips 61, so as to push the multiple easy-open cover strips 61 on the tray 62 flat and stack them neatly.

[0037] In the above scheme, the first guide post 21, the steering gear 321, the first motor 31, the second guide post 41, the second motor 45, and the pusher frame 51 are fixedly mounted on the frame (not shown in the figure), the first transmission wheel 22 located below is rotatably mounted on the frame, the first transmission shaft 322 is rotatably mounted on the frame, and the other second transmission wheel 43 is rotatably mounted on the frame.
