Description

Technical Field

[0001] This utility model relates to the field of palletizer fixture technology, and in particular to a palletizer fixture that is easy to replace the gripper teeth. Background Technology

[0002] A palletizer is a machine that automatically stacks materials, commonly used in fertilizer transportation. It can stack multiple layers and then push them out for easy transport to the warehouse by forklift. This equipment uses PLC + touch screen control to achieve intelligent operation and management, which is simple and easy to master. It can greatly reduce labor and labor intensity. The palletizer is a device that automatically stacks packages conveyed by a conveyor into stacks according to the customer's process requirements and transports the stacked materials. When the palletizer clamps the goods, it needs to use a clamp, so there is an urgent need for a palletizer clamp.

[0003] A search revealed that CN222138092U discloses a palletizer clamp. Through a pressing mechanism, when using the clamp to palletize goods, after the palletizer moves the goods to a designated position, releasing the clamp allows the goods to be stacked at the designated location. If the goods are stacked high, a lifting rod in the pressing mechanism can drive a pressure table to press down, thus pressing and fixing the goods and preventing them from swaying and tipping over during stacking, thereby improving the stability of the palletizer.

[0004] However, this type of clamp requires screwing on each gripper when changing the gripper teeth, which is very troublesome. In addition, the arrangement and height of the grippers are fixed and cannot be flexibly adjusted, which greatly limits its use. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a palletizer fixture that makes it easy to replace the gripper teeth. Existing palletizer fixtures require screwing on each gripper tooth when replacing them, which is very troublesome. In addition, the arrangement and height of the gripper teeth are fixed and cannot be flexibly adjusted, which greatly limits their use.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is a palletizer fixture that facilitates the replacement of gripper teeth, comprising a fixture body, a pressing table, and two clamping arms. The pressing table is fixedly installed on the lower wall of the fixture body. The two clamping arms are respectively hinged to the two sides of the fixture body. Gripper fixing plates are fixedly installed inside the two clamping arms and are respectively connected to the fixture body by cylinders. Pressure grooves are respectively formed on the outer sides of the two gripper fixing plates. A storage structure is provided in the two pressure grooves, and a gripper structure is connected to the storage structure. The pressure grooves and gripper fixing plates are... The structure is connected to a guide structure, which is connected to a limiting structure, and the limiting structure is connected to a locking structure. The storage structure includes several storage slots and several limiting rods. The several storage slots are evenly opened on the inner wall surfaces of two pressure slots, and the several limiting rods are fixedly installed in the several storage slots. The gripping tooth structure includes several tooth handle bodies, several tooth handle limiting holes, and several gripping tooth bodies. The several tooth handle bodies are respectively fitted onto the several limiting rods through the several tooth handle limiting holes, and the several gripping tooth bodies are fixedly installed on the lower end faces of the several tooth handle bodies.

The connecting ends of the four inner wall guide rods and the four outer wall guide rods are respectively threaded and are threadedly connected to the eight locking nuts.

[0008] As a further embodiment of this utility model: the limiting structure includes: two limiting plates, four limiting guide holes and several limiting top blocks; the two limiting plates are respectively fitted onto four inner wall guide rods through the four limiting guide holes, and are slidably connected to the four inner wall guide rods respectively; the several limiting top blocks are respectively fixedly installed on the inner wall surface of the two limiting plates.

[0009] As a further embodiment of this utility model: the spacing between the plurality of limiting top blocks corresponds to the plurality of limiting rods, so as to facilitate the contact between the limiting top blocks and the toothed shank body.

[0010] As a further embodiment of this utility model: the locking structure includes: two locking plates, eight locking guide holes, and eight locking top blocks; the two locking plates are respectively fitted onto the outer wall surfaces of the four inner wall guide rods and the four outer wall guide rods through the eight locking guide holes, and are slidably connected to the four inner wall guide rods and the four outer wall guide rods; the eight locking top blocks are respectively fixedly installed on the inner wall surfaces of the two locking plates, and correspond to the positions of the eight locking guide holes.

[0012] As a further embodiment of this utility model: the edges of several of the gripper teeth bodies are provided with rounded chamfers.

[0013] The present invention adopts the above technical solution and has the following advantages compared with the prior art:

[0014] The modular design allows for quick replacement of single or multiple grippers without the need to screw on and disassemble each gripper body. The gripper body arrangement and specifications can be flexibly adjusted to adapt to different materials, making it highly versatile. The double fixing through locking and limiting structures ensures that the grippers are stable and do not fall off during palletizing, solving the problem that existing palletizer fixtures require screwing on each gripper when replacing grippers, which is very troublesome.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figures 1-4 A palletizer fixture for easy replacement of grippers includes a fixture body 1, a pressing table 2, and two clamping arms 3. The pressing table 2 is fixedly installed on the lower wall of the fixture body 1. The two clamping arms 3 are respectively hinged to the two sides of the fixture body 1. Gripper fixing plates 4 are fixedly installed inside the two clamping arms 3. Pressure grooves 5 are respectively opened on the outer sides of the two gripper fixing plates 4. A storage structure is provided in the two pressure grooves 5, and a gripper structure is connected to the storage structure. A guide structure is connected to the pressure grooves 5 and the gripper fixing plates 4, and a guide structure is connected to the guide structure. The positioning structure includes a locking structure connected to the positioning structure; the storage structure includes: several storage slots 6 and several limiting rods 7; the several storage slots 6 are evenly opened on the inner wall surface of two pressure slots 5, and the several limiting rods 7 are fixedly installed in the several storage slots 6; the gripping tooth structure includes: several tooth handle bodies 8, several tooth handle limiting holes 9 and several gripping tooth bodies 10; the several tooth handle bodies 8 are respectively fitted onto the several limiting rods 7 through the several tooth handle limiting holes 9, and the several gripping tooth bodies 10 are respectively fixedly installed on the lower end face of the several tooth handle bodies 8.

[0023] Please see Figure 3 The guide structure includes: four inner wall guide rods 11, four outer wall guide rods 12, and eight locking nuts 13; the four inner wall guide rods 11 are fixedly installed in the two pressure grooves 5 respectively, and the four outer wall guide rods 12 are fixedly installed on the outer wall surface of the two gripper tooth fixing plates 4. The connecting ends of the four inner wall guide rods 11 and the four outer wall guide rods 12 are respectively threaded and are threadedly connected to the eight locking nuts 13.

[0024] Please see Figure 4 The limiting structure includes: two limiting plates 14, four limiting guide holes 15, and several limiting top blocks 16; the two limiting plates 14 are respectively fitted onto four inner wall guide rods 11 through the four limiting guide holes 15, and are respectively slidably connected to the four inner wall guide rods 11; the several limiting top blocks 16 are respectively fixedly installed on the inner wall surface of the two limiting plates 14.

[0025] Please see Figure 2 The spacing between several limiting top blocks 16 corresponds to several limiting rods 7, which facilitates the contact between the limiting top blocks 16 and the toothed handle body 8. In use, the limiting guide hole 15 of the limiting plate 14 is aligned with the inner wall guide rod 11 and inserted until the several limiting top blocks 16 press against the toothed handle body 8 at the gap of the limiting rods 7 to prevent the toothed handle body 10 from shaking.

[0026] Please see Figure 4The locking structure includes: two locking plates 17, eight locking guide holes 18, and eight locking top blocks 19; the two locking plates 17 are respectively fitted onto the outer wall surfaces of the four inner wall guide rods 11 and the four outer wall guide rods 12 through the eight locking guide holes 18, and are slidably connected to the four inner wall guide rods 11 and the four outer wall guide rods 12; the eight locking top blocks 19 are respectively fixedly installed on the inner wall surfaces of the two locking plates 17, and correspond to the positions of the eight locking guide holes 18.

[0027] Please see Figure 3 Several limiting rods 7 are grouped into groups of three, and the spacing between each group of limiting rods 7 is the same. When in use, the same spacing makes it convenient to push in several limiting top blocks 16.

[0028] Please see Figure 3 Several gripper teeth 10 have rounded chamfers on their edges. When in use, the rounded chamfers on the edges of the gripper teeth 10 can reduce scratches on the material during the gripping process.

[0029] Example 1: In this example, the modular design enables quick replacement of single or multiple gripper teeth without the need to screw on and disassemble each gripper tooth body 10. The arrangement and specifications of the gripper tooth bodies 10 can be flexibly adjusted to adapt to different materials, making it highly versatile. The locking and limiting structure provides double fixation, ensuring that the gripper teeth remain stable and do not fall off during palletizing.

[0030] Specifically, when the gripper body 10 wears out due to long-term use, or when it needs to be replaced with grippers of different specifications according to the material size, the operating steps are as follows: First, unlock the fixing structure. The operator uses a wrench to unscrew the eight locking nuts 13 from the threaded ends of the inner wall guide rod 11 and the outer wall guide rod 12. Then, pull the locking plate 17 outward along the guide rod, so that the locking top block 19 is released from the pressure on the limiting plate 14. Then, pull the limiting plate 14 out along the inner wall guide rod 11, and several limiting top blocks 16 are released from contact with the tooth handle body 8, releasing the limitation on the gripper structure. After that, disassemble the old gripper body 10: move the old gripper body 10 along the limiting rod 7. If only a portion of the worn gripper body 10 needs to be replaced, the corresponding gripper body 8 can be removed selectively without disassembling the entire unit. Then, install a new gripper body 10: select a suitable new gripper body 10 based on the material size. For example, use densely arranged short grippers when gripping small materials, and sparsely arranged long grippers when gripping large materials. Align the gripper limiting hole 9 of the gripper body 8 with the limiting rod 7 and insert it. Adjust the arrangement as needed, with one or several sets of limiting rods 7 spaced apart. Finally, re-tighten: align the limiting guide hole 15 of the limiting plate 14 with the inner wall guide rod 11 and insert it until several limiting top blocks 16 press against the gripper body 8 at the gaps in the limiting rods 7 to prevent the gripper body 10 from shaking. Then, push the locking plate 17 along the inner wall guide rod 11 and the outer wall guide rod 12, so that the locking top block 19 presses against the limiting plate 14. Finally, tighten the locking nut 13 to complete the fixation.

[0031] Example 2: In this example, the height of the gripper teeth can be flexibly adjusted by the multi-position adaptation of the limiting rod; the adjustment process does not require the replacement of parts, the operation is convenient, and the adaptability of the palletizer to materials of different thicknesses is greatly improved.

[0032] Specifically, when the thickness of the palletized object increases, the extension height of the gripper body 10 needs to be increased to ensure a firm grip. The operation is as follows: Following the unlocking steps of Example 1, remove the locking nut 13, locking plate 17, and limiting plate 14 to release the fixation of the tooth handle body 8. Then, pull the tooth handle body 8 along the limiting rod 7 to pull out the gripper body 10. Determine the adjustment height according to the material thickness. Then, align the tooth handle limiting hole 9 with the lower limiting rod 7 and reinsert it. Finally, reinstall the limiting plate 14 and locking plate 17 so that the limiting top block 16 presses against the tooth handle body 8 and the locking nut 13 is fixed in place, completing the height adjustment. After adjustment, the extension length of the gripper body 10 increases, allowing it to penetrate deep into the bottom of thick materials to form a stable grip. If gripping thin materials, the operation can be reversed to reduce the gripper height to avoid the gripper being too long and causing material deformation. The rounded chamfer design of the edge of the gripper body 10 can reduce scratches on the material during clamping.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
