[0002] A palletizer automatically stacks pre-packed cartons onto pallets or stacks (wooden or plastic) in a specific arrangement, allowing for multi-layer stacking. The stacks are then pushed out for easy forklift transport to the warehouse. This equipment uses PLC and touchscreen control for intelligent operation and management, making it simple and easy to use. It significantly reduces labor and labor intensity. A palletizer is a device that automatically stacks bags, cartons, or other packaging materials from a conveyor belt according to customer process requirements, and then transports the stacked materials. However, currently used palletizers cannot effectively adhere to the surface of the goods to fully secure them. Summary of the Invention

[0003] The purpose of this invention is to provide a palletizing machine robot for industrial production, solving the following technical problems:

[0004] The palletizing machines currently in use cannot adhere well to the surface of goods, making it difficult to secure the goods properly.

[0008] The side movable clamp and the side fixed clamp are each provided with a curved plate connecting frame on their opposite sides, and the second extension clamp and the first extension clamp are each provided with a curved plate lower connecting frame on their opposite sides. A curved fastening plate connects the curved plate upper connecting frame and the curved plate lower connecting frame.

[0009] A sliding guide assembly and an anti-slip assembly are provided on one side of the bending fastening plate, and a shock-absorbing airbag is provided on the other side of the bending fastening plate. The sliding guide assembly is located below the anti-slip assembly. The sliding guide assembly includes a sliding ball and a hollow rubber ball connected to the shock-absorbing airbag. The anti-slip assembly includes several anti-slip plates that are inclined.

[0010] Furthermore, the sliding ball is embedded into one side of the curved fastening plate through a groove, and the hollow rubber ball is fixedly installed on one side of the curved fastening plate. Several sliding balls and hollow rubber balls are provided, and the several sliding balls and hollow rubber balls are arranged at intervals. The hollow rubber balls are connected to the shock-absorbing airbag through an air guide hose.

[0011] Furthermore, telescopic cylinders are installed at the top of both the second extension clamp and the first extension clamp. A gear is rotatably mounted on one side of the second extension clamp via a mounting bracket. A hook plate is fixedly connected to one side of the gear, and a clamping spring is provided at the end of the hook plate.

[0012] Furthermore, a toothed plate is fixedly mounted on one side of the side-moving clamp via a mounting plate, and a toothed strip corresponding to the gear is provided on one side of the toothed plate, and the toothed strip meshes with the gear.

[0013] Furthermore, the top sliding mounting mechanism includes: a top horizontal plate, a sliding mounting block, and a fixed mounting block. A fixed mounting block is installed on one side of the top horizontal plate, and a sliding mounting block is slidably connected to the inside of the top horizontal plate through a sliding groove.

[0014] Furthermore, a sliding sleeve is installed at the bottom end of the top horizontal plate, and sliding mounting rods are slidably connected to both ends of the sliding sleeve. An adsorption mechanism is connected to the bottom end of each of the two sliding mounting rods.

[0015] Furthermore, the adsorption mechanism includes a suction cup, an inner telescopic rod, and an outer telescopic tube. The inner telescopic rod is fixedly installed at the bottom end of the sliding mounting rod, and the outer telescopic tube is slidably connected to the outer side of the inner telescopic rod. The inner wall of the outer telescopic tube is provided with a rubber layer.

[0016] Furthermore, the bottom end of the inner rod of the telescopic column is connected to the inner bottom end of the outer tube of the telescopic column through a support spring. A suction cup is provided at the bottom end of the outer tube of the telescopic column. An air guide groove runs through the suction cup. The inner cavity of the air guide groove is connected to the inner cavity of the outer tube of the telescopic column.

[0019] The beneficial effects of this invention are:

[0020] This invention, by incorporating a side-fixed clamping plate, a side-moving clamping plate, a bending fastening plate, sliding balls, and hollow rubber balls, allows for the clamping of a cargo box. When clamping the cargo box, a drive cylinder, via a cylinder push rod, drives a sliding mounting block to slide. This sliding mounting block, in turn, moves the side-moving clamping plate, ensuring the distance between the side-moving clamping plate and the side-fixed clamping plate is slightly greater than the cargo box itself. This initiates the clamping process. Under the action of the sliding balls and hollow rubber balls, the cargo box quickly slides between the two bending fastening plates. An anti-slip plate on one side of the bending fastening plate increases friction against the cargo box. Simultaneously, the cargo box is fixed to the side-moving clamping plate and the side-fixed clamping plate. After the clamping plates are positioned, the bending fastening plate is compressed, and the shock-absorbing airbag is also compressed. The shock-absorbing airbag forces air into the hollow rubber ball, causing the hollow rubber ball to expand and compress the outside of the cargo box, increasing the friction on the cargo box and making the cargo box clamped more securely. At the same time, the telescopic cylinder can drive the second extension clamping plate and the first extension clamping plate to move upward. The second extension clamping plate and the first extension clamping plate drive the bending fastening plate to bend further toward the cargo, making the bending fastening plate clamp the cargo better. The compressed bending fastening plate can better fit the surface of the cargo, fully securing the cargo. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-5 As shown, the present invention is a palletizing machine robot for industrial production, comprising a top sliding mounting mechanism and a clamping mechanism located below it;

[0030] The clamping mechanism includes: a side fixed clamping plate 18 and a side movable clamping plate 12; each side fixed clamping plate 18 is provided with a first extension clamping plate 19 inside, the first extension clamping plate 19 extending to the outside of the side fixed clamping plate 18; each side movable clamping plate 12 is provided with a second extension clamping plate 17 inside, the second extension clamping plate 17 extending to the outside of the side movable clamping plate 12.

[0031] A curved plate connecting frame 5 is provided on the opposite side of the side moving clamp 12 and the side fixed clamp 18. A curved plate lower connecting frame 14 is provided on the opposite side of the second extended clamp 17 and the first extended clamp 19. A curved fastening plate 9 is connected between the curved plate upper connecting frame 5 and the curved plate lower connecting frame 14.

[0032] The fixed mounting block 8 is mounted on the robotic arm of the palletizer via the mounting bracket on one side. When the cargo box is gripped, the drive cylinder 2 drives the sliding mounting block 6 to slide through the cylinder push rod 3. The sliding mounting block 6 drives the side moving clamp 12 to move, so that the distance between the side moving clamp 12 and the side fixed clamp 18 is slightly larger than the cargo box.

[0033] A sliding guide assembly and an anti-slip assembly are provided on one side of the bending fastening plate 9, and a shock-absorbing airbag 13 is provided on the other side of the bending fastening plate 9. The sliding guide assembly is located below the anti-slip assembly. The sliding guide assembly includes a sliding ball 11 and a hollow rubber ball 10 connected to the shock-absorbing airbag 13. The anti-slip assembly includes several anti-slip pieces 7 that are inclined.

[0034] The goods are clamped and the cargo box is quickly slid between two curved fastening plates 9 under the action of the sliding ball 11 and the hollow rubber ball 10. The anti-slip plate 7 on one side of the curved fastening plate 9 can increase the friction on the cargo box. The shock-absorbing airbag 13 squeezes air into the hollow rubber ball 10, which can increase the friction on the cargo box.

[0035] In one embodiment of the present invention, a sliding ball 11 is embedded in one side of a curved fastening plate 9 via a groove, and a hollow rubber ball 10 is fixedly installed on one side of the curved fastening plate 9. Several sliding balls 11 and hollow rubber balls 10 are provided, spaced apart. The hollow rubber balls 10 are connected to the shock-absorbing airbag 13 via a flexible air duct. Simultaneously, after the cargo box is fixed between the side moving clamp 12 and the side fixing clamp 18, the curved fastening plate 9 is compressed, and the shock-absorbing airbag 13 is compressed. The shock-absorbing airbag 13 forces air into the hollow rubber ball 10, causing the hollow rubber ball 10 to expand and compress the outside of the cargo box, increasing the friction between the hollow rubber ball 10 and the cargo box, thus making the cargo box clamped more securely.

[0036] In one embodiment of the present invention, telescopic cylinders are installed at the top ends of both the second extension clamping plate 17 and the first extension clamping plate 19. A gear 27 is rotatably mounted on one side of the second extension clamping plate 17 via a mounting bracket. A hook plate 21 is fixedly connected to one side of the gear 27, and a clamping spring 28 is provided at the end of the hook plate 21. After the item is clamped, the telescopic cylinders can drive the second extension clamping plate 17 and the first extension clamping plate 19 to move upward. The second extension clamping plate 17 and the first extension clamping plate 19 drive the bending fastening plate 9 to bend further toward the goods, so that the bending fastening plate 9 can better clamp the goods.

[0037] In one embodiment of the present invention, a toothed plate 16 is fixedly mounted on one side of the lateral moving clamp 12 via a mounting plate. A toothed strip 15 corresponding to the gear 27 is provided on one side of the toothed plate 16, and the toothed strip 15 meshes with the gear 27. After the item is clamped, if the goods need to be lifted by the hook plate 21, the second extended clamp 17 can be adjusted to descend a short distance, causing the gear 27 to descend. The toothed plate 16 then moves upward relative to the gear 27, causing the toothed strip 15 to rotate the gear 27. The gear 27 then rotates the hook plate 21 clockwise, causing the clamping spring 28 at the end of the hook plate 21 to press down on the goods, thus clamping them from the top. Since the distance the second extended clamp 17 moves is less than half the circumference of the gear 27, it does not affect the clamping of the goods.

[0038] In one embodiment of the present invention, the top sliding mounting mechanism includes: a top horizontal plate 1, a sliding mounting block 6, and a fixed mounting block 8. The fixed mounting block 8 is mounted on one side of the top horizontal plate 1, and the sliding mounting block 6 is slidably connected to the inside of the top horizontal plate 1 through a sliding groove. The side moving clamp 12 can be moved by the sliding mounting block 6.

[0039] In one embodiment of the present invention, a sliding sleeve 20 is installed at the bottom end of the top horizontal plate 1, and sliding mounting rods 29 are slidably connected to both ends of the sliding sleeve 20. An adsorption mechanism is connected to the bottom end of each of the two sliding mounting rods 29.

[0040] In one embodiment of the present invention, the adsorption mechanism includes a suction cup 22, an inner telescopic rod 25, and an outer telescopic tube 24. The inner telescopic rod 25 is fixedly installed at the bottom end of the sliding mounting rod 29, and the outer telescopic tube 24 is slidably connected to the outer side of the inner telescopic rod 25. A rubber layer is provided on the inner wall of the outer telescopic tube 24. When the outer telescopic tube 24 is suddenly subjected to a downward pulling force, the outer telescopic tube 24 moves downward a short distance. The rubber layer can ensure the airtightness between the inner telescopic rod 25 and the outer telescopic tube 24, thereby creating a negative pressure inside the outer telescopic tube 24.

[0041] In one embodiment of the present invention, the bottom end of the inner rod 25 of the telescopic column is connected to the inner bottom end of the outer tube 24 of the telescopic column through a support spring 23. A suction cup 22 is provided at the bottom end of the outer tube 24 of the telescopic column. An air guide groove 26 runs through the inside of the suction cup 22. The inner cavity of the air guide groove 26 is connected to the inner cavity of the outer tube 24 of the telescopic column. An exhaust one-way valve is installed on one side of the outer tube 24 of the telescopic column. When clamping goods, the suction cup 22 assists the side moving clamp 12 and the side fixed clamp 18 to clamp the goods. The suction cup 22 presses down on the goods, and the inner rod 25 of the telescopic column discharges the air in the outer tube 24 of the telescopic column through the exhaust one-way valve. When the palletizer robot lifts the goods, the goods are suddenly lifted, and the goods drive the suction cup 22 and the outer tube 24 of the telescopic column to move downward. A negative pressure is formed inside the outer tube 24 of the telescopic column. The inside of the outer tube 24 of the telescopic column is connected to the suction cup 22 through the air guide groove 26, so that the suction cup 22 can better adhere to the top of the goods, and increase the fixing force on the goods when the goods are suddenly lifted.

[0042] In one embodiment of the present invention, both the sliding mounting block 6 and the fixed mounting block 8 are connected to the corresponding sliding mounting rod 29 via an L-shaped connecting frame 4. A mounting bracket is provided on the side of the fixed mounting block 8 away from the L-shaped connecting frame 4. The L-shaped connecting frame 4 allows the suction cup 22 at the bottom of the sliding mounting rod 29 to better assist the side moving clamp 12 and the side fixed clamp 18 in clamping the goods.

[0043] In one embodiment of the present invention, a driving cylinder 2 is provided at the top of the top horizontal plate 1, and a cylinder push rod 3 is connected to the output end of the driving cylinder 2. The cylinder push rod 3 is connected to the top of the sliding mounting block 6 through a fixing bracket.

[0044] The working principle of this invention: The mounting bracket on one side of the fixed mounting block 8 is installed on the robotic arm of the palletizer. When gripping the cargo box, the drive cylinder 2 drives the sliding mounting block 6 to slide through the cylinder push rod 3. The sliding mounting block 6 drives the side moving clamping plate 12 to move, so that the distance between the side moving clamping plate 12 and the side fixed clamping plate 18 is slightly larger than the cargo box, and the cargo box begins to be gripped. Under the action of the sliding ball 11 and the hollow rubber ball 10, the cargo box can quickly slide between the two curved fastening plates 9. The anti-slip plate 7 on one side of the curved fastening plate 9 can increase the friction on the cargo box; at the same time, the cargo box... After the container is fixed between the side moving clamp 12 and the side fixing clamp 18, the bending fastening plate 9 is compressed, and the shock-absorbing airbag 13 is also compressed. The shock-absorbing airbag 13 forces air into the hollow rubber ball 10, causing the hollow rubber ball 10 to expand and compress the outside of the container, increasing the friction on the container and making the container more securely clamped. After the item is clamped, the telescopic cylinder can move the second extension clamp 17 and the first extension clamp 19 upwards. The second extension clamp 17 and the first extension clamp 19 then cause the bending fastening plate 9 to bend further toward the item, making the bending fastening plate... 9. Better clamping of goods; after clamping the item, if the hook plate 21 needs to lift the item, the second extended clamping plate 17 can be adjusted to descend a short distance, driving the gear 27 to descend. The toothed plate 16 then moves upward relative to the gear 27, the toothed strip 15 drives the gear 27 to rotate, and the gear 27 drives the hook plate 21 to rotate clockwise. This causes the clamping spring 28 at the end of the hook plate 21 to press down on the item, clamping it from the top. Since the distance the second extended clamping plate 17 moves is less than half the circumference of the gear 27, it does not affect the clamping of the item. When clamping the item... The suction cup 22 can also be used to assist the side moving clamp 12 and the side fixing clamp 18 in clamping the goods. The suction cup 22 presses down on the goods, and the inner rod 25 of the telescopic column discharges the air in the outer tube 24 of the telescopic column through the exhaust one-way valve. When the palletizer robot lifts the goods, the goods are suddenly lifted, and the goods drive the suction cup 22 and the outer tube 24 of the telescopic column to move downward. A negative pressure is formed inside the outer tube 24 of the telescopic column. The inside of the outer tube 24 of the telescopic column is connected to the suction cup 22 through the air guide groove 26, so that the suction cup 22 can better adhere to the top of the goods, and increase the fixing force on the goods when the goods are suddenly lifted.
