Detailed Implementation

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0023] like Figure 1-6 As shown, a palletizing device for stacking goods includes:

[0024] The rotating part is used for placing the goods 1. The rotating part can be used to drive the goods 1 above to rotate and can control the movement of the goods 1 on the rotating part.

[0025] The lifting section is located on both sides of the rotating section and is used to move the goods 1 on the rotating section upward or downward.

[0026] The transfer section is used to place the pallet 3. The transfer section can transfer the pallet 3 to the rotating section, and the lifting section can place the lifted goods 1 onto the pallet 3.

[0027] Furthermore, the rotating part includes a base platform 4, a sleeve 5 is fixedly mounted on the upper surface of the base platform 4, a gear ring 6 is fixedly mounted on the outer side of the sleeve 5, a mounting platform 7 is mounted above the base platform 4, a column 8 is mounted on the lower surface of the mounting platform 7, the column 8 is rotatably connected to the sleeve 5, a motor 9 is mounted on the lower surface of the mounting platform 7, a gear 10 that meshes with the gear ring 6 is mounted on the output end of the motor 9, and a conveying part 11 is mounted on the upper surface of the mounting platform 7.

[0028] Stacking involves placing goods 1 onto pallets 3. When goods 1 are moving along the conveyor belt, they are placed on wooden bases 2. Because the wooden bases 2 are relatively thin, the height of goods 1 during movement can be reduced, thus improving stability. However, during storage, it is necessary to increase the distance between goods 1 and the ground to prevent water accumulation on the ground from threatening goods 1. Therefore, goods 1 and bases 2 need to be placed together on plastic pallets 3.

[0029] When goods 1 with chassis 2 are transferred to conveyor section 11 via an external conveyor belt or forklift, conveyor section 11 needs to transport goods 1 and chassis 2 to its center position. Chassis 2 has slots in only one direction. When chassis 2 is first placed on conveyor section 11, the lifting unit cannot enter the slot on chassis 2. To facilitate the lifting unit lifting chassis 2 and goods 1 through the slot, the position of chassis 2 needs to be adjusted so that chassis 2 rotates 90°, allowing the lifting unit to enter the slot on pallet 3. Therefore, when adjusting the position of chassis 2, motor 9 needs to be started. Motor 9 drives gear 10 to rotate, and then through the meshing of gear 10 with gear ring 6, it drives mounting platform 7 and column 8 to rotate. When mounting platform 7 and column 8 rotate 90°... After the temperature reaches 30°, motor 9 stops rotating. Then, the lifting part lifts the chassis 2 and the cargo 1 through the slot on the chassis 2. After the chassis 2 and the cargo 1 are lifted, the output end of motor 9 is reversed, causing the mounting platform 7 and the conveyor 11 to rotate 90° in the opposite direction, completing the reset of the conveyor 11. A single pallet 3 is pre-placed on the transfer part. The transfer part can transport the pallet 3 to the conveyor 11. When the pallet 3 reaches the center position of the conveyor 11, the conveyor 11 stops moving. Then, the lifting part places the lifted chassis 2 and the cargo 1 onto the conveyor 11. Then, the lifting part leaves the chassis 2. Next, the pallet 3, chassis 2 and cargo 1 are transferred from the conveyor 11 to the transfer part. Then, the cargo 1 on the transfer part is transferred out by a forklift lifting the pallet 3.

[0030] Furthermore, support legs 12 are respectively provided at the four corners of the lower surface of the mounting platform 7. The lower end of the support leg 12 is 2mm away from the upper surface of the base platform 4. Since the weight of the goods 1 is relatively heavy, when the goods 1 just enters the conveyor section 11 from the outside, the conveyor section 11 and the mounting platform 7 will tilt due to the uneven distribution of the weight of the goods 1 above. At this time, the support leg 12 abuts against the base platform 4 to prevent the conveyor section 11 and the mounting platform 7 from tilting further. When the goods 1 move to the center position of the conveyor section 11, the weight distribution on the conveyor section 11 and the mounting platform 7 is relatively uniform, and the lower end of the support leg 12 does not contact the base platform 4, thereby avoiding friction between the support leg 12 and the base platform 4 during the rotation of the mounting platform 7.

[0031] The column 8 and the sleeve 5 are connected by a bearing, which can be either a thrust ball bearing or a thrust roller bearing.

[0032] Motor 9 can be equipped with a servo motor, which controls the mounting platform 7 to rotate at a specified angle through a closed-loop control system. It is also equipped with hardware such as encoders, drivers, and controllers, and uses a PID controller to ensure that the mounting platform 7 rotates at a specified angle within the allowable error range.

[0033] Furthermore, the lifting unit includes a mounting frame 13, which has two mounting channels. A rotating part is located between the two mounting channels. Fork plate assemblies are installed inside each of the two mounting channels. A traction assembly for simultaneously raising and lowering the two fork plate assemblies is installed above the mounting frame 13. Each fork plate assembly includes a lifting frame 14 located within a mounting channel. The lifting frame 14 is slidably connected to the mounting channel. A support frame 15 is installed on the inner surface of the lifting frame 14 and is slidably connected to the lifting frame 14. A cylinder 16 is installed inside the lifting frame 14, and the output end of the cylinder 16 is fixedly connected to the support frame 15. One end of the support frame 15... The end is provided with a front fork plate 17. The traction assembly includes a second motor 18 mounted on a mounting frame 13. The output end of the second motor 18 is provided with two drive sprockets 19. The mounting frame 13 is provided with a rotating shaft 20 on both sides of the second motor 18. Each rotating shaft 20 is provided with two driven sprockets 21. Each lifting frame 14 is provided with two chains 22. One end of each chain 22 is fixedly connected to the lifting frame 14. The other end of one chain 22 is fixedly connected to the driven sprocket 21. The other end of the other chain 22 passes over the other driven sprocket 21 and is fixedly connected to the drive sprocket 19.

[0034] When lifting the chassis 2 and cargo 1 using the lifting unit, the support frame 15 needs to be pushed outward from the lifting frame 14 by the cylinder 16. When the support frame 15 is pushed out, it will drive the fork plate 17 to move and push the fork plate 17 into the slot on the chassis 2. After the fork plate 17 has entered the slot to an appropriate length, the output end of the cylinder 16 stops extending. Then, the second motor 18 is started. The two drive sprockets 19 on the output end of the second motor 18 rotate simultaneously and simultaneously wind up the chain 22. One of the driven sprockets 21 on the shaft 20 also starts to wind up the chain 22 at the same time, thereby raising the height of the lifting frame 14. After the height of the lifting frame 14 rises, the height of the fork plate 17 located in the lifting frame 14 will also rise. Therefore, the chassis 2 and cargo 1 can be lifted upward by the fork plate 17. The height between chassis 2 and conveyor 11 needs to be greater than the height of pallet 3 so that pallet 3 can enter under chassis 2. After pallet 3 enters directly under chassis 2, the output end of motor 18 rotates in the opposite direction, and the drive sprocket 19 and one of the driven sprockets 21 start to release the winding chain 22, thereby lowering the height of fork plate 17. After chassis 2 moves onto pallet 3, fork plate 17 will continue to lower by 1-2 cm to ensure that chassis 2 is placed on pallet 3 and that fork plate 17 is completely separated from chassis 2. Then the output end of cylinder 16 retracts to remove fork plate 17 from chassis 2. At this time, pallet 3, chassis 2 and cargo 1 can be transferred from conveyor 11 to transfer unit via conveyor 11 and transfer unit.

[0035] The hanging frame 14 and the mounting bracket 13, as well as the support frame 15 and the hanging frame 14, are connected by a slide rail module. This improves the stability of the hanging frame 14 when it moves up and down, and the stability of the support frame 15 when it moves horizontally. It also prevents the hanging frame 14 from separating from the mounting bracket 13, and the support frame 15 from the hanging frame 14.

[0036] Cylinder 16 is powered by an external air supply assembly.

[0037] Furthermore, the transfer unit includes a placement table 23, on which a second conveyor unit 24 is provided.

[0038] The placement platform 23 is used to keep the height of the second conveyor section 24 approximately the same as the height of the first conveyor section 11, so that the goods 1 on the first conveyor section 11 can enter the second conveyor section 24 normally, and the pallet 3 on the second conveyor section 24 can enter the first conveyor section 11. Both the first conveyor section 11 and the second conveyor section 24 are composed of multiple chain conveyor belts, and the multiple conveyor belts in the first conveyor section 11 and the second conveyor section 24 are driven by synchronous shafts to ensure that the multiple conveyor belts in the first conveyor section 11 and the second conveyor section 24 can move and stop synchronously. At the same time, it is necessary to control the first conveyor section 11 and the second conveyor section 24 to maintain approximately the same running speed. The first conveyor section 11 and the second conveyor section 24 are controlled by separate motors.

[0039] The actions of motor 19, motor 218, cylinder 16, conveyor 11, and conveyor 24 in this application are all controlled by a PLC system and equipped with corresponding photoelectric sensors to detect whether the goods 1 and pallet 3 are in place, so as to ensure the normal operation of the equipment.
