Technical Field

[0001] This utility model relates to the field of palletizing technology, and in particular to a high-level palletizing machine. Background Technology

[0002] High-level palletizers are palletizing equipment suitable for large chemical enterprises, featuring fast palletizing speed, high stability, and easy maintenance. Currently, when high-level palletizers are in operation, workers mostly place pallets sequentially on the conveyor mechanism according to the palletizing frequency to achieve continuous palletizing; this method is labor-intensive, time-consuming, and labor-intensive for workers. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a high-level palletizing machine.

[0004] This utility model provides a high-level palletizing machine, including a bag feeding mechanism, a conveying mechanism, a lifting mechanism, and a palletizing mechanism, as well as a pallet feeding mechanism. The pallet feeding mechanism includes a feeding bracket straddling the conveying mechanism, a feeding lifting frame vertically slidingly fitted in the feeding bracket, and a pallet support arm adapted to the width of the pallet arranged opposite to the feeding lifting frame. The pallet support arm is provided with pallet support fingers and a support finger driving mechanism. The support finger driving mechanism is used to drive the pallet support fingers to extend into the insertion holes in the pallet, thereby driving the pallet to rise and fall through the feeding lifting frame.

[0005] Compared with the prior art, the beneficial effects of this utility model are as follows: At the start of production, a forklift is used to place the stacked pallets on the conveying mechanism and to one side of the pallet feeding mechanism. The feeding lifting frame drives the pallet support arm to move to the outside of the second layer of pallets from the bottom. The support finger drive mechanism drives the pallet support fingers to insert into the holes in the pallets. The feeding lifting frame drives the pallet support arm to rise and lift the second layer of pallets from the bottom and the pallets above it. After the first layer of pallets from the bottom is stacked, the feeding lifting frame drives the pallet support arm to fall, thereby placing the remaining pallets on the conveying mechanism. After placement, the feeding lifting frame again drives the pallet support arm to move to the outside of the second layer of pallets from the bottom. The support finger drive mechanism drives the pallet support fingers to insert into the holes in the pallets. The feeding lifting frame drives the pallet support arm to rise and lift the second layer of pallets from the bottom and the pallets above it. This process is repeated to achieve automatic pallet supply.

[0006] Optionally, the finger support drive mechanism includes a rotary drive shaft rotatably connected to the tray support arm. A finger drive cylinder is provided on the tray support arm on one side of the rotary drive shaft. A drive connecting rod is hinged to the piston rod end of the finger drive cylinder. The drive connecting rod is fixedly connected to the rotary drive shaft. The tray support finger is fixedly fixed on the rotary drive shaft in an L-shape.

[0007] Optionally, the conveying mechanism includes a first conveying mechanism, a second conveying mechanism, and a third conveying mechanism connected in sequence. The first conveying mechanism adopts a sprocket and chain conveying mechanism, while the second and third conveying mechanisms adopt roller conveying mechanisms. In the second conveying mechanism, a roller drive sprocket set is provided on the lower side between adjacent rollers, and the adjacent rollers are driven by the roller drive sprocket set and the chain.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0022] See Figures 1-8 This utility model provides a high-level palletizing machine, including a bag-loading mechanism 1, a conveying mechanism 2, a lifting mechanism 3, and a palletizing mechanism 4, as well as a pallet feeding mechanism 5. The pallet feeding mechanism 5 includes a feeding bracket 6 straddling the conveying mechanism 2. A feeding lifting frame 7 is vertically slidably fitted in the feeding bracket 6. A pallet support arm 9 adapted to the width of the pallet 8 is arranged opposite to the feeding lifting frame 7. A pallet support finger 10 and a support finger driving mechanism 11 are arranged on the pallet support arm 9. The support finger driving mechanism 11 is used to drive the pallet support finger 10 to extend into the insertion hole in the pallet 8, thereby driving the pallet 8 to rise and fall through the feeding lifting frame 7.

[0023] The lifting drive of the loading lifting frame 7 can be achieved by common drive structures such as pneumatic cylinders, electric cylinders, and lead screw pairs.

[0024] At the start of production, a forklift is used to place the stacked pallets 8 on the conveying mechanism 2 and to one side of the pallet loading mechanism 5. The loading lifting frame 7 moves the pallet support arm 9 to the outside of the second layer of pallets 8. The support finger drive mechanism 11 drives the pallet support fingers 10 to insert into the holes in the pallets 8. The loading lifting frame 7 then moves the pallet support arm 9 up to lift the second layer of pallets 8 and the pallets above it. After the first layer of pallets is stacked, the loading lifting frame 7 moves the pallet support arm 9 down to place the remaining pallets 8 on the conveying mechanism 2. After placement, the loading lifting frame 7 again moves the pallet support arm 9 to the outside of the second layer of pallets 8. The support finger drive mechanism 11 drives the pallet support fingers 10 to insert into the holes in the pallets 8. The loading lifting frame 7 then moves the pallet support arm 9 up to lift the second layer of pallets 8 and the pallets above it. This process is repeated to achieve automatic pallet 8 supply.

[0025] In implementation, the finger-supporting drive mechanism 11 includes a rotary drive shaft 12 rotatably connected to the tray support arm 9. A finger-drive cylinder 13 is provided on one side of the rotary drive shaft 12 on the tray support arm 9. A drive connecting rod 14 is hinged to the piston rod end of the finger-drive cylinder 13. The drive connecting rod 14 is fixedly connected to the rotary drive shaft 12. The tray-supporting finger 10 is fixedly fixed on the rotary drive shaft 12 in an L-shape. In specific configuration, the length of the rotary drive shaft 12 can be similar to that of the tray support arm 9 and is set along the bottom surface of the tray support arm 9. The end of the cylinder body of the finger-drive cylinder 13 is hinged to the tray support arm 9 to accommodate the adjustment of the position and posture during the rotation of the rotary drive shaft 12 using the drive connecting rod 14.

[0026] In implementation, the conveying mechanism 2 includes a first conveying mechanism 15, a second conveying mechanism 16, and a third conveying mechanism 17 connected in sequence. The first conveying mechanism 15 adopts a sprocket and chain conveying mechanism, and the pallet 8 is placed on the chain to be conveyed to the second conveying mechanism 16. The second conveying mechanism 16 and the third conveying mechanism 17 adopt a roller conveying mechanism. In the second conveying mechanism 16, a roller drive sprocket group 18 is provided on the lower side between adjacent rollers. The adjacent rollers are driven by the roller drive sprocket group 18 and the chain. The roller drive sprocket group 18 includes at least two sprockets. One sprocket is driven by a chain to a roller on one side, and the other sprocket is driven by a chain to a roller on the other side.

[0027] In practice, the lifting mechanism 3 includes a lifting support frame 19, in which a lifting frame 20 is vertically slidably fitted. The lifting frame 20 is rectangular in shape, and its width is slightly greater than the length of the roller in the second conveying mechanism 16. The lifting frame 20 is provided with a support beam 21 that matches the gap between adjacent rollers in the second conveying mechanism 16. This arrangement allows the lifting frame 20 to be lowered to a position below the roller surface, thereby enabling the pallet 8 to be moved onto the lifting frame 20.

[0028] The lifting drive of the lifting frame 20 can be achieved using a sprocket and chain drive structure. Specifically, a lifting drive shaft 22 can be installed on the lower side of the lifting frame 20 within the lifting support frame 19. A drive sprocket is installed on the lifting drive shaft 22 corresponding to the two corner positions on the first side of the lifting frame 20. A first driven sprocket 23 is installed on the lifting support frame 19 above the drive sprockets, and a second driven sprocket 24 is installed on the lifting support frame 19 above the two corner positions on the second side of the lifting frame 20. A first lifting drive chain 25 is installed between the drive sprockets and the first driven sprocket 23. The two corner positions on the first side of the lifting frame 20 are fixed to the first lifting drive chain 25. A second lifting drive chain 26 is connected to the first lifting drive chain 25, and the second lifting drive chain 26 passes around the second driven sprocket 24 and is fixed to the two corner positions on the second side of the lifting frame 20. Alternatively, an electric cylinder structure can be used. For example, electric cylinders can be installed on the lifting support frame 19 at positions corresponding to the four corners of the lifting frame 20, using these electric cylinders to drive the lifting frame 20.

[0029] In implementation, a longitudinal moving frame 27 is slidably fitted on the top of the lifting support frame 19 along the moving direction of the tray 8. A transverse moving frame 28 is slidably fitted in the longitudinal moving frame 27, and a bag-shaped material gripping robot 29 is installed in the transverse moving frame 28. The drive of the longitudinal moving frame 27 can be realized by a gear and rack structure, such as setting a rack on the lifting support frame 19, setting a drive motor on the longitudinal moving frame 27, and setting a gear on the output shaft of the drive motor that meshes with the rack; similarly, the drive of the transverse moving frame 28 can also be realized by a gear and rack structure, with the rack set on the longitudinal moving frame 27 and the drive motor set on the transverse moving frame 28; the bag-shaped material gripping robot 29 is an existing mechanical structure and will not be described in detail here.

[0030] In practice, the bag-loading mechanism 1 adopts a roller conveying mechanism. A lifting frame 30 is set between the rollers in the bag-loading mechanism 1. A lifting drive cylinder 31 for driving the lifting frame 30 to rise and fall is set on the lower side of the lifting frame 30. The lifting frame 30 is used to lift the bag material upward when the bag material gripping robot 29 grips the bag material, thereby improving the gripping convenience.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
