Description

Technical Field

[0001] This invention relates to the field of automated storage and retrieval systems (AS / RS), and more specifically to a conveying and conversion device for AS / RS. Background Technology

[0002] Existing warehousing and conveying equipment transports materials that need to be sorted and transported according to weight. Most existing sorting and conveying devices weigh the materials on electronic scales and then place them on the corresponding conveyor lines based on the weight. Some specific materials, due to their shape, are not convenient to place on shelves, so they need to be placed in pallets before being transported. In this process, the materials are usually placed on pallets manually. Weighing and placing materials on pallets takes up a lot of time and is labor-intensive. Summary of the Invention

[0003] The purpose of this invention is to provide a conveying and conversion device for an automated warehouse to solve the problems mentioned in the background art.

[0004] A conveying and conversion device for an automated warehouse includes a frame; a base plate is provided at the center of the frame, and a connecting weighing device, a conversion and sorting device, and a lifting device are provided on the base plate. Incoming material conveyor belts and pallet conveyor lines are respectively provided on the front and rear sides of the frame of the connecting weighing device, and an outgoing material conveyor line is provided on the left and right sides of the frame. The connecting weighing device is used to connect to the pallet conveyor line and receive pallets from the pallet conveyor line. The lifting device can raise the conversion and sorting device above the conveyor rollers in the connecting weighing device, thereby connecting the two outgoing material conveyor lines and sorting incoming materials of different weights onto different outgoing material conveyor lines. The incoming material conveyor belt is used to transport materials and place them into the pallets on the connecting weighing device.

[0005] Preferably, the connecting weighing device includes a conveyor frame and a load-bearing plate. The conveyor frame is provided with a plurality of conveyor rollers, and the bottom of the conveyor frame is provided with a support rod. The support rod is slidably connected to a bracket provided on the base plate. The bottom of the support rod passes through the bracket and is fixedly connected to the load-bearing plate. The load-bearing plate is provided on the electronic scale. The electronic scale is fixedly connected to the base plate. A spring is sleeved on the support rod between the bracket and the conveyor frame.

[0006] Preferably, the conveying roller is also fitted with anti-slip sleeves on both sides.

[0007] Preferably, the conversion and sorting device includes a support frame, which has several equidistantly arranged support frames, all located between adjacent conveyor rollers. A row of synchronous pulleys is rotatably connected to the upper end of the support frame, and synchronous pulleys are rotatably connected to the lower end of the support frame. Synchronous pulleys 1 and 2 within the same support frame are connected by a synchronous belt. Several synchronous pulleys 2 are fixedly connected to the same drive shaft. The drive shaft is fixedly connected to the output shaft of a motor. The motor is fixedly connected to one of the support frames.

[0008] Preferably, when the support frame is at its lowest point, the upper surface of its timing belt is lower than the highest point of the anti-slip sleeve; when the support frame is at its highest point, the upper surface of its timing belt is flush with the highest point of the roller of the discharge conveyor line.

[0009] Preferably, the lifting device includes a lifting cylinder, the output shaft of the lifting cylinder is fixedly connected to a lifting plate, the bottom of the lifting plate is fixedly connected to a guide rod, the guide rod is slidably connected to the base plate, and the support frame is fixedly connected to the lifting plate.

[0010] Preferably, the frame on the front side of the connecting weighing device is also equipped with a proximity switch to detect whether there is a tray above it.

[0011] Preferably, the heights of the incoming conveyor belt, the outgoing conveyor line, and the pallet conveyor line decrease sequentially.

[0012] The advantages of this invention are:

[0013] By setting up a connecting weighing device, a conversion sorting device, and a lifting device between the pallet conveyor line and the incoming material conveyor belt, the pallet can be transported to the connecting weighing device, where the material on the incoming material conveyor belt will fall onto the pallet. The connecting weighing device will then weigh the material and control the forward or reverse rotation of the synchronous belt based on the weight, so that the incoming material enters the corresponding outgoing conveyor line.

[0014] It eliminates the need for manual sorting and placing materials on pallets, saving time and costs. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4 As shown, a conveying and conversion device for an automated warehouse includes a frame 1; a base plate 2 is provided at the center of the frame 1, and a connecting weighing device 3, a conversion and sorting device 4, and a lifting device 5 are provided on the base plate 2. The frame 1 on the front and rear sides of the connecting weighing device 3 is provided with an incoming material conveyor belt 6 and a pallet conveyor line 7, respectively, and an outgoing material conveyor line 8 is provided on the left and right sides of the frame 1. The connecting weighing device 3 is used to connect to the pallet conveyor line 7 and receive pallets from the pallet conveyor line 7. The lifting device 5 can lift the conversion and sorting device 4 so that it is higher than the conveyor roller 33 in the connecting weighing device 3, thereby connecting the two outgoing material conveyor lines 8, so as to sort incoming materials of different weights onto different outgoing material conveyor lines 8. The incoming material conveyor belt 6 is used to transport materials and put the materials into the pallets on the connecting weighing device 3.

[0025] In this embodiment, the connecting weighing device 3 includes a conveyor frame 31 and a load-bearing plate 32. The conveyor frame 31 is equipped with several conveying rollers 33, and a support rod 34 is located at the bottom of the conveyor frame 31. The support rod 34 is slidably connected to a bracket 35 mounted on the base plate 2. The bottom of the support rod 34 passes through the bracket 35 and is fixedly connected to the load-bearing plate 32. The load-bearing plate 32 is mounted on an electronic scale 36, which is fixedly connected to the base plate 2. A spring 37 is sleeved on the support rod 34 between the bracket 35 and the conveyor frame 31. The elastic force of the spring 37 can precisely offset the weight of the conveyor frame 31, the conveying rollers 33, the support rod 34, and the load-bearing plate 32, thus providing support for them.

[0026] In this embodiment, anti-slip sleeves 38 are also fitted on both sides of the conveyor roller 33. The anti-slip sleeves 38 are used to increase the friction with the pallet.

[0027] In this embodiment, the conversion and sorting device 4 includes a support frame 41. Several support frames 41 are equidistantly arranged and are all located between adjacent conveyor rollers 33. A row of synchronous pulleys 42 is rotatably connected to the upper end of the support frame 41, and synchronous pulleys 43 are rotatably connected to the lower end of the support frame 41. The synchronous pulleys 42 and 43 in the same support frame 41 are connected by a synchronous belt 44. Several synchronous pulleys 43 are fixedly connected to the same drive shaft 45. The drive shaft 45 is fixedly connected to the output shaft of a motor 46. The motor 46 is fixedly connected to one of the support frames 41.

[0028] In this embodiment, when the support frame 41 is at its lowest point, the upper surface of its synchronous belt 44 is lower than the highest point of the anti-slip sleeve 38. When the support frame 41 is at its highest point, the upper surface of its synchronous belt 44 is flush with the highest point of the roller of the discharge conveyor line 8.

[0029] In this embodiment, the lifting device 5 includes a lifting cylinder 51, the output shaft of the lifting cylinder 51 is fixedly connected to a lifting plate 52, the bottom of the lifting plate 52 is fixedly connected to a guide rod 53, the guide rod 53 is slidably connected to the base plate 2, and the support frame 41 is fixedly connected to the lifting plate 52.

[0030] In this embodiment, the frame 1 on the front side of the connecting weighing device 3 is also provided with a proximity switch 9 to detect whether there is a tray above it.

[0031] In this embodiment, the heights of the incoming conveyor belt 6, the outgoing conveyor line 8, and the pallet conveyor line 7 decrease sequentially. This ensures that the material on the incoming conveyor belt 6 can fall smoothly onto the pallet, and the pallet can be conveyed to the outgoing conveyor line 8 under the support of the support frame 41.

[0032] Working process and its principle:

[0033] The pallet is conveyed on the pallet conveyor line 7. When the pallet enters the conveyor roller 33 connected to the weighing device 3, the proximity switch 9 detects that the pallet has reached the designated position and starts the incoming material conveyor belt 6. The material on the incoming material conveyor belt 6 will be transported under the conveying action of the incoming material conveyor belt 6 and fall into the pallet. At this time, the weight of the pallet and the incoming material acts on the conveyor roller 33, and is sequentially transferred by the conveyor roller 33 to the conveyor frame 31, the support rod 34 and the load-bearing plate 32. The electronic scale weighs the force applied to it by the load-bearing plate 32, thereby obtaining the weight of the material entering the pallet. This weight is compared with the weight range corresponding to the two outgoing conveyor lines 8 to obtain the result.

[0034] When the lifting cylinder 51 is activated, the output shaft extends and the lifting plate 52 rises, causing all the support frames 41 to rise together. When the support frames 41 rise, the synchronous belt 44 will contact the bottom of the pallet. Then, as the support frames 41 continue to move upward, the pallet will rise under the support of the synchronous pulley 42. Finally, the pallet will disengage from the conveyor roller 33 and be lifted until its bottom is just level with the highest point of the roller of the discharge conveyor line 8. At this point, the lifting cylinder 51 will be closed.

[0035] Motor 46 starts, its direction determined by the previous weight result. It then drives drive shaft 45 to rotate, causing synchronous pulley 43 to rotate, which in turn causes synchronous belt 44 and synchronous pulley 42 to rotate together. The rotating synchronous belt 44 transports the pallet to the corresponding discharge conveyor line 8, completing the sorting and placement of the material onto the pallet. For further weight-based sorting of the material, connecting conveyor devices, conversion sorting devices 4, and lifting devices 5 can be installed on discharge conveyor line 8 to achieve a second sorting, resulting in more refined material sorting.

[0036] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
