Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and in particular to a chain lifting conveying structure and equipment using the chain lifting conveying structure. Background Art

[0002] A common chain conveyor consists of pulleys and a chain. The pulleys are located at the front and rear ends, driving the chain. The chain can only move in a straight line, along the line connecting the two belts. To achieve chain steering, steering chain conveyors have been developed. These pulleys are located within a circle and are designed to be tapered. However, steering chain conveyors can only move within a certain arc, making it difficult to achieve stable transportation in the vertical direction.

[0003] When using chains to transport materials between multiple workstations, and the workstations are not located in a straight line, multiple chains must be connected in series to adjust the material conveying direction. However, this method requires a large number of chains, occupies a large area, and the connection between the chains makes it easy for materials to fall and even fall off the chain, resulting in poor conveying efficiency. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention proposes a chain lifting and conveying structure and equipment using the chain lifting and conveying structure, which can achieve stable conveying in the up and down directions and the front and back directions, and can fully utilize the layout of the upper and lower spaces, greatly saving the use space.

[0005] To implement the above technical solution, the present invention provides a chain lifting and conveying structure, including: a first chain stacking conveying assembly and a second chain stacking conveying assembly distributed in parallel and at intervals along the Y direction, the first chain stacking conveying assembly and the second chain stacking conveying assembly have the same structure, both including multiple gears, a double chain and multiple trays installed on the double chain, wherein the multiple gears are distributed in an S shape along the Z direction, the last gear and the first gear are distributed in parallel and at intervals along the X direction, the second to last gear and the second gear are distributed in parallel and at intervals along the X direction, and the third to last gear and the fourth to last gear are distributed in parallel and at intervals along the X direction, the double chain connects all the gears in series, and multiple trays are evenly fixed on the double chain.

[0006] In the above technical solution, during actual operation, the gears arranged in an S-shape along the Z direction utilize the space in the Z direction, and the last gear and the first gear are arranged in parallel and spaced relation along the X direction, utilizing the space in the X direction. Even if the positions of multiple workstations are not in a straight line, the up-down and front-to-back structural layout of the chain stacking conveyor assembly can be fully utilized to meet the conveying requirements of different workstations. Moreover, the structure of connecting all the gears in series with a double chain can reduce the number of chains and reduce the risk of chain detachment. The first chain stacking conveyor assembly and the second chain stacking conveyor assembly adopt a layout with parallel and spaced relation along the Y direction, which can greatly expand the conveying space and fully utilize the space in the X, Y, and Z directions, greatly improving the efficiency of space utilization and conveying.

During actual operation, a four-layer Z-direction stacked conveying structure is formed between the first to eighth gears, and then the X-direction conveying is realized by utilizing the parallel and spaced distribution between the first and tenth gears along the X-direction, thereby making full use of the space in the X-direction and Z-direction and improving space utilization efficiency.

[0009] Preferably, the pallet in the first chain stacking conveyor assembly is fixed on the inner side of the double chain, and the pallet in the second chain stacking conveyor assembly is fixed on the outer side of the double chain, so that the space in the Y direction between the first chain stacking conveyor assembly and the second chain stacking conveyor assembly can be further utilized.

A first double chain 21 connects the ten gears in series, and twenty-eight trays 23 are evenly spaced and fixed to first double chain 21. In actual operation, a four-layer Z-direction stacked conveying structure is formed between first gear 1 to eighth gear 8. X-direction conveying is then achieved by utilizing the space between first gear 1 and tenth gear 10, spaced parallel to each other along the X-direction. This fully utilizes the space in both the X- and Z-directions and improves space efficiency.

[0020] The second chain stacking conveying assembly also includes ten gears, a second double chain 22 and twenty-eight trays 23, wherein the eleventh gear 11 and the twentieth gear 20 are spaced apart and arranged in parallel along the X direction, the twelfth gear 12 is installed on the upper right of the eleventh gear 11, the thirteenth gear 13 is installed on the upper left of the twelfth gear 12, and the thirteenth gear 13 is located directly above the eleventh gear 11, the fourteenth gear 14 is installed on the upper right of the thirteenth gear 13, and the fourteenth gear 14 is located directly above the twelfth gear 12, the fifteenth gear 15 is installed on the upper left of the fourteenth gear 14, and the fifteenth gear 15 is located directly above the eleventh gear 11.

The first chain stacking conveyor assembly or the first chain stacking conveyor assembly is provided with a driving gear connected to an external drive mechanism. During actual operation, the external drive mechanism can drive the driving gear to rotate, thereby driving all gears and the double chains to rotate, and further driving the movement of the trays mounted on the double chains.

[0023] This chain lifting and conveying structure is cleverly designed and simple in structure. It can achieve stable conveying in the up and down directions (Z direction) and the front and back directions (X direction), and can make full use of the layout of the upper and lower spaces, greatly saving the use of space. In actual operation, the gears distributed in an S shape along the Z direction form the utilization of the Z-direction space, and the last gear and the first gear are distributed in parallel and spaced along the X direction to form the utilization of the X-direction space. Even if the positions of multiple workstations are not in a straight line, the up and down, front and back structural layout of the chain stacking conveying assembly can be fully utilized to meet the conveying requirements of different workstations. Moreover, the structure of connecting all the gears in series with a double chain can reduce the number of chains and reduce the risk of chain falling off. The first chain stacking conveying assembly and the second chain stacking conveying assembly adopt a layout with parallel and spaced distribution along the Y direction, which can greatly expand the conveying space and make full use of the space in the X, Y and Z directions, greatly improving the efficiency of space use and the efficiency of conveying.

During actual operation, the drive motor 500 drives the gears in the chain lifting and conveying structure 100 to rotate through the reduction box 400, thereby driving the tray 23 on the double chain to circulate back and forth. External materials are transported from the left to the tray at the chain lifting and conveying structure 100 via the conveyor belt 300. After the tray 23 travels up and down along the path of the chain lifting and conveying structure 100, the materials are finally output from the right end of the frame 200.
