Description

Technical Field

[0001] This utility model belongs to the field of cargo palletizing technology, and in particular relates to an auxiliary positioning structure for palletizing racks. Background Technology

[0002] Pallet racks are warehousing equipment used for stacking and storing goods. They are usually made of metal materials, such as steel, and are sturdy and durable. They can bear a certain weight of goods and provide a stable stacking platform, allowing goods to be stacked neatly and orderly, improving the utilization of warehouse space. Appropriate pallet racks can be selected for stacking based on the shape, size, and weight of the goods.

[0003] Palletizing racks can neatly stack goods and make full use of the vertical space of the warehouse. However, during the palletizing process, goods may tilt or fall due to inaccurate stacking positions. Inaccurate stacking positions may also affect the overall stability of multi-layer palletizing racks and increase the risk of stack collapse. Therefore, it is necessary to provide a palletizing rack auxiliary positioning structure that uses an automatic four-corner squeezing positioning method to assist multiple palletizing racks in achieving accurate positioning during the palletizing process, thereby improving the overall stability of multi-layer palletizing racks.

[0022] In the following description, embodiments of the palletizing rack auxiliary positioning structure of this utility model will be described with reference to the accompanying drawings.

[0023] Figure 1-4 illustrates an embodiment of the auxiliary positioning structure for a palletizing rack of this utility model, including a palletizing platform 1: protective frames 2 are fixedly connected to both sides of the top of the palletizing platform 1, and positioning components 3 are provided on both sides of the top of the palletizing platform 1. The positioning components 3 are rotatably connected to a rotating column 31 inside the cavity of the protective frame 2. Connecting bent arms 32 are fixedly connected to the top and bottom of the surface of the rotating column 31. A connecting column 33 is rotatably connected to one end of the two connecting bent arms 32 away from the rotating column 31. Limiting blocks 6 are fixedly connected to the surface of the connecting bent arms 32, and one side of the limiting block 6 is tightly pressed against the surface of the triangular side plate 34. The connecting column 33 is tightly fitted with torsion springs 7 on both the top and bottom. One end of the torsion spring 7 is welded to the connecting arm 32, and the other end is welded to the triangular side plate 34. The top and bottom of the connecting column 33 are fixedly connected with triangular side plates 34. Two extrusion cylinders 35 are rotatably connected to the inner cavity of the triangular side plate 34. The inner cavity of the stacking platform 1 is provided with a drive assembly 4. The drive assembly 4 includes toothed plates 41 slidably connected to both sides of the inner cavity of the stacking platform 1. Two limiting blocks 8 are fixedly connected to both sides of the bottom of the inner cavity of the stacking platform 1. The front and rear sides of the bottom of the toothed plates 41 are provided with... The limiting groove 9, which is compatible with the limiting block 8, plays a limiting and guiding role for the toothed plate 41 through the cooperation of the limiting block 8 and the limiting groove 9. This allows the toothed plate 41 to maintain stable horizontal sliding, thereby enabling the toothed plate 41 to maintain a stable meshing transmission state with the gear 42. The bottom end of the rotating column 31 penetrates into the inner cavity of the stacking platform 1 and is fixedly connected to the gear 42. The gear 42 meshes with the toothed plate 41. A bidirectional threaded rod 43 is rotatably connected to the top of the inner cavity of the stacking platform 1. The toothed plate 41 is threadedly connected to the surface of the bidirectional threaded rod 43. The top of the inner cavity of the stacking platform 1 is fixedly connected to the gear 42. A stepper motor 44 is fixedly installed. The output shaft of the stepper motor 44 and the surface of the bidirectional threaded rod 43 are both fixedly connected to a pulley 45. The two pulleys 45 are connected by belt drive. With the setting of the drive assembly 4, the two toothed plates 41 are simultaneously threaded and pushed by the stepper motor 44, so that the two toothed plates 41 can slide towards each other or away from each other at the same time, thereby causing the gear 42 to rotate and drive the rotating column 31 to rotate. Multiple stacking racks 5 are stacked on the top of the stacking platform 1.

[0024] Working Principle: In use, the user stacks pallet racks 5 onto the top of the palletizing platform 1. After each pallet rack 5 is stacked, the stepper motor 44 starts, driving the bidirectional threaded rod 43 to rotate via the pulley 45 and belt. Due to the threaded action on the surface of the bidirectional threaded rod 43, the two toothed plates 41 move in opposite directions. Under the meshing transmission of the toothed plates 41 and the gear 42, the gear 42 rotates, driving the rotating column 31 to rotate. During the rotation of the rotating column 31, the connecting arm 32 flips, causing the extrusion cylinder 35 to contact the corner of the pallet rack 5 under the action of the connecting arm 32, and subjected to the torsional force of the torsion spring 7. The two adjacent extrusion cylinders 35 can be accurately positioned on both sides of the palletizing frame 5. Under the extrusion of the extrusion cylinders 35 and the blocking action of the palletizing frame 5, the two adjacent extrusion cylinders 35 can be in close contact with the surface of the palletizing frame 5. Under the extrusion of the extrusion cylinders 35, the four corners of the palletizing frame 5 are extruded, so that the palletizing frames 5 stacked one by one are positioned, thereby ensuring the stability of multiple palletizing frames 5 after stacking. After a single positioning, the stepper motor 44 rotates in the opposite direction and drives the bidirectional threaded rod 43 to rotate in the opposite direction, so that the two toothed plates 41 move towards each other, so that the rotating column 31 drives the connecting column 33 and the extrusion cylinder 35 to rotate and reset through the connecting bent arm 32, waiting for the second positioning.

[0025] In summary, this palletizing rack auxiliary positioning structure, through the setting of the driving component 4, provides driving force to the positioning component 3. At the same time, with the cooperation of the positioning component 3 and the protective frame 2, the palletizing rack 5 located on the top of the palletizing platform 1 is squeezed and aligned at four corners, so that multiple palletizing racks 5 can be aligned neatly, thus achieving the purpose of automatic squeezing positioning and accurate multi-point alignment.
