Description

Technical Field

[0001] This utility model relates to the field of warehousing equipment technology, and in particular to a lifting and transferring machine for dual-station pallets. Background Technology

[0002] Warehousing and logistics refers to the core links of a modern supply chain that uses systematic and intelligent methods to store, handle, sort, and manage goods. It is widely used in manufacturing, e-commerce, and retail industries. This system is based on an automated storage and retrieval system (AS / RS), integrating intelligent equipment such as stacker cranes, conveyor lines, AGVs (Automated Guided Vehicles), and shuttle cars. Through high-density rack storage, precise location allocation, and automated storage and retrieval scheduling, it significantly improves turnover efficiency.

[0003] In the warehousing and logistics industry, to improve conveying efficiency, it is sometimes necessary to transport two pallets simultaneously. This necessitates a lifting and transferring machine capable of handling pallets at two workstations at the same time. Currently, such scenarios typically employ two independent lifting and transferring machines deployed side-by-side, each handling one workstation. However, this solution has significant limitations. First, a safety distance must be maintained between the two machines to prevent mechanical interference, resulting in a large lateral space requirement and making it difficult to adapt to compact factory layouts. Second, the dual-machine system requires two independent drive motors, transmission mechanisms, and control systems, increasing the cost of equipment deployment and subsequent maintenance. Furthermore, component redundancy increases energy consumption and the risk of failure.

[0004] Therefore, it is necessary to provide a lifting and transferring machine for dual-station pallets to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a lifting and transferring machine for dual-station pallets to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: A lifting and transferring machine for a dual-station pallet includes a conveying unit with two stations. The conveying unit includes an upper frame, on which a conveying transmission unit is mounted. The conveying transmission unit includes a parallel shaft reduction motor, a conveying transmission shaft, and conveying sprockets. The parallel shaft reduction motor is fixed on the upper frame, and the conveying transmission shaft passes through the hollow shaft of the parallel shaft reduction motor. Multiple sets of conveying sprockets are fixed on the conveying transmission shaft, and a conveying chain is engaged between every two conveying sprockets. A lifting unit for lifting the upper frame is provided below the conveying unit.

[0007] As a further embodiment of this utility model, the lifting part includes a base, on which a lifting reduction motor is fixed. A drive sprocket is mounted on the output shaft of the lifting reduction motor. A bearing seat is fixed on the base, and a transmission shaft is rotatably connected to the bearing seat. A driven sprocket is fixed on the side of the transmission shaft. A transmission chain meshes between the drive sprocket and the driven sprocket. Swing arms are fixed at both ends of the transmission shaft, and the upper frame is lifted by rotating the swing arms.

[0008] As a further embodiment of this utility model, the bottom of the upper frame is fixed with a plurality of symmetrically distributed lifting guide seats, and the base is fixed with a slider that slides in cooperation with the lifting guide seats.

[0009] As a further embodiment of this utility model, a proximity sensor is fixed on the base, and a position sensing plate is fixed on the upper frame. The position sensing plate and the proximity sensor work together to detect the position of the conveying unit.

[0010] As a further embodiment of this utility model, the lifting reduction motor is a helical bevel gear reduction motor.

[0011] As a further embodiment of this utility model, the position sensing plate and the proximity sensor are respectively located at the ends of the upper frame and the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The output of the parallel shaft geared motor drives the conveyor drive shaft to rotate, which in turn drives the conveyor sprocket to rotate. The conveyor sprocket then drives the conveyor chain to move, thus realizing the conveying function and conveying the pallets. It can convey two pallets synchronously. The conveying unit uses a parallel shaft geared motor to drive the chain movement. One motor drives the conveyor chain of two workstations, which effectively simplifies the transmission structure. It has the characteristics of compact structure, small space occupation, and strong driving force. The new structural design reduces the space occupied and lowers the equipment cost, effectively solving the problems of large space occupation and high cost when using single workstations side by side.

[0014] 2. The position sensing plate can move up and down with the upper frame. When the position sensing plate is close to the proximity sensor, it can sense the position of the upper frame, thereby obtaining the accurate position of the upper frame and ensuring the accuracy of the transfer.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1-5This utility model provides a lifting and transferring machine for a dual-station pallet, including a conveying unit 2 with two stations. The conveying unit 2 includes an upper frame 21, on which a conveying transmission unit 22 is mounted. The conveying transmission unit 22 includes a parallel shaft reduction motor 221, a conveying transmission shaft 222, and conveying sprockets 223. The parallel shaft reduction motor 221 is fixed to the upper frame 21. The conveying transmission shaft 222 passes through the hollow shaft of the parallel shaft reduction motor 221, and multiple sets of conveying sprockets 223 are fixed on the conveying transmission shaft 222. Every two conveying sprockets 223 mesh with a conveying chain 23. A lifting unit for lifting the upper frame 21 is provided below the conveying unit 2. 1. In operation, the lifting unit 1 lifts the conveying unit 2 upwards, thereby adjusting its height. The output of the parallel shaft reduction motor 221 drives the conveying drive shaft 222 to rotate, which in turn drives the conveying sprocket 223 to rotate. The sprocket 223 then moves the conveying chain 23, thus achieving the conveying function and transporting pallets. Two pallets can be transported synchronously. The conveying unit 2 uses a parallel shaft reduction motor 221 to drive the chain movement; one motor drives the conveying chains 23 at two workstations, effectively simplifying the transmission structure. This design features a compact structure, small footprint, and strong driving force. The new structural design reduces space requirements and lowers equipment costs, effectively solving the problems of large space requirements and high costs associated with parallel use at single workstations.

[0025] Further as Figure 1 and Figure 2 As shown, it is worth noting that the lifting unit 1 includes a base 11, on which a lifting reduction motor 12 is fixed. A drive sprocket 13 is mounted on the output shaft of the lifting reduction motor 12. A bearing seat 18 is fixed on the base 11, and a transmission shaft 16 is rotatably connected to the bearing seat 18. A driven sprocket 15 is fixed on the side of the transmission shaft 16. A transmission chain 14 meshes between the drive sprocket 13 and the driven sprocket 15. Both ends of the transmission shaft 16 are fixed with swing arms 17. The upper frame 21 is lifted by rotating the swing arms 17. In actual operation, the output end of the lifting reduction motor 12 drives the drive sprocket 13 to rotate, thereby driving the transmission shaft 16 to rotate and adjust through the cooperation of the drive sprocket 13, the driven sprocket 15, and the transmission chain 14. This causes the swing arms 17 to rotate, lifting the upper frame 21 and adjusting the height of the conveying unit 2.

[0026] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the bottom of the upper frame 21 is fixed with multiple symmetrically distributed lifting guide seats 24, and the base 11 is fixed with a slider 19 that slides in cooperation with the lifting guide seats 24. In actual operation, when the upper frame 21 moves up and down for adjustment, the slider fixed on the base 11 slides in the lifting guide seat 24, thereby playing a guiding role and improving the stability of the movement adjustment of the upper frame 21.

[0027] Further as Figure 2 and Figure 3 As shown, it is worth noting that a proximity sensor 110 is fixed on the base 11, and a position sensing plate 25 is fixed on the upper frame 21. The position sensing plate 25 and the proximity sensor 110 work together to detect the position of the conveying unit 2. The position sensing plate 25 is fixed on the upper frame 21 and can move up and down with the upper frame 21. When the position sensing plate 25 approaches the proximity sensor 110, it can sense the position of the upper frame 21, thereby obtaining the accurate position of the upper frame 21 and ensuring the accuracy of the transfer.

[0028] This solution has the following working process: The output end of the lifting reduction motor 12 drives the drive sprocket 13 to rotate, thereby driving the drive shaft 16 to rotate and adjust through the cooperation of the drive sprocket 13, driven sprocket 15 and transmission chain 14, thereby causing the swing arm 17 to rotate. The swing arm 17 lifts the upper frame 21, and the output end of the parallel shaft reduction motor 221 drives the conveyor transmission shaft 222 to rotate, thereby driving the conveyor sprocket 223 to rotate, and then driving the conveyor chain 23 to move through the conveyor sprocket 223, thereby realizing the conveying function and conveying the pallet.

[0029] Further as Figure 2 As shown, it is worth noting that the lifting reduction motor 12 is a helical bevel gear reduction motor; the swing arm 17 is driven by the helical bevel gear reduction motor, which has the characteristics of compact structure and large driving torque.

[0030] Further as Figure 2 and Figure 3 As shown, it is worth noting that the position sensing plate 25 and the proximity sensor 110 are respectively located at the ends of the upper frame 21 and the base 11.

[0031] In summary: The lifting unit 1 lifts the conveying unit 2 upwards, thereby adjusting its height. The output of the parallel shaft reduction motor 221 drives the conveyor drive shaft 222 to rotate, which in turn drives the conveyor sprocket 223 to rotate. This, in turn, moves the conveyor chain 23, thus achieving the conveying function and transporting pallets. Two pallets can be transported synchronously. Furthermore, the conveying unit 2 uses a parallel shaft reduction motor 221 to drive the chain movement; one motor drives the conveyor chains 23 at two workstations, effectively simplifying the transmission structure. This design features a compact structure, small footprint, and strong driving force. The new structural design reduces space requirements and lowers equipment costs, effectively solving the problems of large space requirements and high costs associated with parallel use at single workstations.
