[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] like Figure 1-8 As shown, a roller lift includes:

[0025] Ramp 3;

[0026] The conveyor section is used to place the tray 1 and can transfer the tray 1 from the conveyor section.

[0027] The lifting section is located on both sides of the conveyor section and is used to drive the conveyor section to move up and down.

[0028] After the forklift picks up the pallet 1, it can move to the top of the conveyor via the ramp 3, so that the pallet 1 can be stably placed on the roller 6. The ramp 3 is made of plastic and has a honeycomb or other shaped reinforcing rib structure inside so that the ramp 3 can support the forklift, the pallet 1 and the wire pack 2.

[0029] Furthermore, the conveying unit includes an upper-opening mounting groove 4, and three extension grooves 5 are provided on the side of the mounting groove 4. The length of the extension grooves 5 on both sides is greater than the length of the middle extension groove 5, and the lengths of the extension grooves 5 on both sides are the same. Rotatable rollers 6 are provided inside the mounting groove 4 and the extension grooves 5. Two sprockets 7 are provided at both ends of the rollers 6 in the extension grooves 5 on both sides and at both ends of the rollers 6 in the mounting groove 4. Adjacent rollers 6 are driven by sprockets 7 and chains 8. A power unit 9 for driving the rollers 6 to rotate is provided on one side of the mounting groove 4.

[0030] Both the mounting groove 4 and the extension groove 5 are cut and welded from steel plates. The rollers 6 include two specifications: the shorter rollers 6 located in the extension grooves 5 on both sides, the shortest roller 6 located in the middle extension groove 5, and the longest roller 6 located in the mounting groove 4. The rollers 6 in the mounting groove 4 and the two side extension grooves 5 can rotate via the power unit 9 and the cooperation of the sprocket 7 and chain 8. When the pallet 1 and the wire package 2 on the pallet 1 are placed on the rollers 6 in the two side mounting grooves 4, the movement of the pallet 1 and the wire package 2 can be achieved by controlling the rotation of the rollers 6. Simultaneously, the rollers in the middle extension groove 5... Roller 6 is mainly used to support the middle of pallet 1. Under normal circumstances, the height of roller 6 located in extension groove 5 is slightly lower than the horizontal height of roller 6 located in extension groove 5 on both sides, so that pallet 1 can press on roller 6 in extension groove 5 on both sides. When pallet 1 is subjected to the weight of yarn bundle 2, the middle part of pallet 1 will bend and deform downward, and the downward extension distance is about 5mm. Roller 6 located in the middle extension groove 5 can prevent pallet 1 from deforming severely. At the same time, since most of the weight of pallet 1 and yarn bundle 2 is pressed on roller 6 in extension groove 5 on both sides, it can ensure that pallet 1 and yarn bundle 2 maintain linear movement on the conveyor.

[0031] Limiting plates 29 are provided on both sides of the extension groove 5 and the mounting groove 4. When the pallet 1 is placed on the roller 6, the pallet 1 is located between the two limiting plates 29. The limiting plates 29 make it easy to determine whether the placement position of the pallet 1 is effective, avoid excessive deviation of the placement position of the pallet 1, and also prevent the pallet 1 from sliding out of the side roller 6 when it moves on the roller 6.

[0032] The power unit 9 can be composed of a motor, reducer, controller, etc., and is used to drive the roller 6 to rotate. All rollers 6 located in the mounting groove 4 and the extension grooves 5 on both sides rotate in the same direction.

[0033] Furthermore, a stop block 10 is provided at one end of the extension groove 5 located in the middle, and the upper end of the stop block 10 is provided with a chamfer.

[0034] When pallet 1 is moved by a forklift, the chamfer on the stop block 10 can prevent pallet 1 from colliding with the extension groove 5 in the middle due to the downward protrusion of the middle part. The chamfer can help guide pallet 1 to the top of roller 6 and prevent the extension groove 5 from being damaged by the impact between pallet 1 and extension groove 5.

[0035] Furthermore, the lifting section includes two lifting units, each lifting unit including a housing 11. A movable box 12 is slidably connected inside the housing 11. Pulleys 13 are respectively provided on both sides of the movable box 12. The pulleys 13 can roll along the inner wall of the housing 11. A side cavity 14 is connected through the side of the housing 11. A transmission unit is provided inside the housing 11 and the side cavity 14. The transmission units in the two lifting units are driven by a main shaft 15. The section also includes a second power unit 16 for driving the two transmission units to work simultaneously.

[0036] The transmission unit includes shaft 19, shaft 20, shaft 31, shaft 42, shaft 53, and shaft 64. Shaft 19 and shaft 20 are arranged side by side at the upper end of housing 11, and shaft 31 and shaft 523 are arranged side by side at the lower end of housing 11. Shaft 31 is located below the middle of shaft 19 and shaft 20, and shaft 523 is located below shaft 20. Shaft 42 is located inside housing 11 and above shaft 523. Shaft 624 is located in side cavity 14. Two sprockets 25 are fixedly installed on shaft 19, shaft 20, shaft 31, shaft 42, shaft 523, and shaft 624. The unit also includes a straight chain 26 and a chain 37. One end of chain 26 is fixedly connected to the movable box 12, and the other end of chain 26 is connected sequentially from shaft 19, shaft 20, shaft 32, shaft 42, shaft 523, and shaft 624. After passing through shafts 20, 22, 24, 23, and 21, they are fixedly connected to the movable box 12. One end of chain 3 27 is fixedly connected to the movable box 12, and the other end of chain 3 27 passes through shafts 20, 22, 24, 23, and 21 in sequence before being fixedly connected to the movable box 12. Shaft 6 24 is the driving shaft, and the other shafts are driven shafts. Both ends of the main shaft 15 are fixedly connected to two shafts 6 24 respectively. A set of power units 2 16 is provided. The output end of power unit 2 16 is fixedly connected to one of the shafts 6 24. When power unit 2 16 drives shaft 6 24 to rotate, it can drive chain 2 26 and chain 3 27 to move, thereby driving the movable box 12 to move up and down. When the movable box 12 moves up and down, it can also drive the conveyor to move up or down.

[0037] The second power unit 16 can be composed of a motor, reducer, controller, etc., and is used to drive the movable box 12 to move up or down. Since the two transmission units are driven by the main shaft 15, the movable boxes 12 in the two housings 11 can keep up and down synchronously. At the same time, since the second chain 26 and the third chain 27 are exposed, it is convenient to apply lubricating grease to the second chain 26 and the third chain 27. It is also necessary to regularly observe the tension of the second chain 26 and the third chain 27 for timely maintenance.

[0038] Meanwhile, the lifting speed of the movable box 12 is about 10cm / s, which ensures the stable lifting of the conveyor, pallet 1 and wire pack 2, while also preventing the chain from disengaging from the sprocket.

[0039] Furthermore, a base plate 17 is provided between the two housings 11, and a protective plate 18 is provided on the base plate 17, with the main shaft 15 located on the back side of the protective plate 18.

[0040] There is a gap of about 8cm between the guard plate 18 and the main shaft 15. When the pallet 1 and the wire package 2 are transported to the conveyor by a forklift, the main shaft 15 is not easy to see, and the pallet 1 may hit the main shaft 15, causing the main shaft 15 to bend. The guard plate 18 can block the pallet 1, thereby avoiding the pallet 1 from directly hitting the main shaft 15 and reducing the occurrence of impact on the main shaft 15. The guard plate 18 is a steel plate with a thickness of 1.2mm. It can be bent after being squeezed and can return to its original shape after the compression is released.

[0041] When placing the pallet 1 containing the silk package 2 onto the conveyor belt 28 on the production line, the pallet 1 and the silk package 2 are first forked onto the conveyor section by a forklift. Then, the lifting section controls the conveyor section to be raised to a certain height, so that the lower end of the pallet 1 is slightly higher than the conveyor belt 28. Next, the roller 6 on the conveyor section is controlled to rotate, moving the pallet 1 onto the conveyor belt 28. The conveyor belt 28 is continuously in operation, so it can promptly transfer the received pallet 1 and silk package 2 out. After the pallet 1 and silk package 2 are transferred out of the conveyor section, the lifting section controls the conveyor section to reset, so that the pallet 1 and silk package 2 can be transferred onto the conveyor belt 28 again.
