Description

Technical Field

[0001] This invention relates to the field of logistics loading and unloading technology, and in particular to a material handling device and method. Background Technology

[0002] In recent years, logistics loading and unloading technology has developed rapidly, resulting in a variety of automated loading devices. Currently, the loading process of automated loading devices is as follows: materials are fed to the telescopic conveyor by manual labor, robotic arms, or sorting conveyors; the telescopic conveyor transports the materials to the automated loading device; and the automated loading device stacks the materials into the truck bed.

[0003] Patent application CN202510162002.9 discloses an automatic loading device and method for bagged materials in a sealed truck compartment. The device in this patent can only dock with the end of a telescopic conveyor to retrieve materials, and cannot retrieve materials from the first section of the conveyor. Therefore, space needs to be reserved between the end of the telescopic conveyor and the truck compartment for the loading device. This results in the automatic loading device occupying too much space outside the warehouse and encroaching on vehicle parking spaces.

[0033] Corresponding to the material handling device provided by the present invention, the embodiments of the present invention also provide a material handling method. Figure 8 This is a schematic diagram illustrating the material handling device of an embodiment of the present invention handling material in the first section of a telescopic conveyor. (In conjunction with...) Figure 8 The method provided by the present invention includes the following steps S11 to S15: S11: The material taking component 4 moves along the conveying direction of the telescopic conveyor 2 to the starting material taking position C of the first section of the telescopic conveyor 2; S12: The material taking component 4 raises the belt conveyor surface at the starting material taking position C of the telescopic conveyor 2, so that the belt conveyor surface behind the starting material taking position C of the first section of the telescopic conveyor 2 is higher than the belt conveyor surface in front, thereby forming a step between the belt conveyor surface behind the starting material taking position C and the belt conveyor surface in front.

[0034] like Figure 8 As shown, the material handling assembly 4 raises the second roller 405 ( Figure 4 The first motor 411 drives the linear motion module 410 to drive the second roller 405 to move upward along the groove A. Since the positions of the three redirecting rollers 406 are fixed, the belt conveyor surface behind the second roller 405 will be higher than the belt conveyor surface in front of the second roller 405, thus forming a step.

[0035] S13: The inclined conveyor assembly 5 rotates around the second drive shaft 505 in the vertical plane until the end of the inclined conveyor assembly 5 near the telescopic machine 2 is at the same height as the starting material picking position C. The inclined conveyor assembly 5 rotates around the second drive shaft 505 in a vertical plane, so that the inclined conveyor assembly 5 is close to the upper side of the lower step at one end of the telescopic machine 2, and controls the conveyor belt at this end of the inclined conveyor assembly 5 to be at the same height as the conveyor surface of the belt 201 at the starting material pick-up position C of the first section of the telescopic machine 2.

[0036] S14: Transport the material 1 at the starting material pick-up position C of the first section of the telescopic conveyor 2 to the inclined conveyor assembly 5; Among them, the belt 201 on the drive ramp conveyor 5 moves from back to front, and in conjunction with the telescopic conveyor 2, it conveys the material 1 at the starting material pick-up position C to the ramp conveyor 5, and the ramp conveyor 5 continues to convey it forward to the automatic loading device.

[0037] S15: When the material 1 at the starting pick-up position C of the first section of the telescopic conveyor 2 is conveyed to the inclined conveyor component 5, the pick-up component 4 moves backward in the opposite direction of the conveying direction of the telescopic conveyor 2, and the inclined conveyor component 5 moves synchronously with the pick-up component 4 in the same direction, so as to realize continuous pick-up at different positions on the first section of the telescopic conveyor 2.

[0038] In this process, the telescopic conveyor 2 continuously conveys material 1 forward, while the material taking component 4 moves backward in the opposite direction of the conveying direction of the telescopic conveyor 2. The inclined conveying component 5 moves synchronously with the material taking component 4 to take material. Since the feeding direction of the telescopic conveyor is opposite to the movement direction of the material taking component 4, the material taking speed can be greatly accelerated and the material taking efficiency can be improved.

[0039] This completes the objective of retrieving material from the first section of the telescopic conveyor 2.

[0040] Preferably, when the inclined conveying assembly 5 does not need to pick up material from the first section of the telescopic conveyor 2, after S14, the method of the present invention further includes step S15: the material picking assembly 4 lowers the belt conveyor surface of the telescopic conveyor 2.

[0041] Figure 9 This is a schematic diagram illustrating the conveying state of the material-retrieving component when the inclined conveyor component is not retrieving material. Figure 9 As shown, when the inclined conveyor assembly does not need to pick up material on the first section of the telescopic conveyor 2, the second roller 405 is controlled to move downward along the groove A to a low position, so that the height difference between the front and rear belt conveyor surfaces at the starting material picking position of the first section of the telescopic conveyor 2 is less than a preset threshold. Preferably, the second roller 405 is positioned so that its height is less than the height difference between the front and rear belt conveyor surfaces at the starting material picking position of the first section of the telescopic conveyor 2. Figure 9 The height of the upper right-side redirecting roller 406 of the second roller 405 is consistent with that of the middle roller. At this time, the conveyor belt 201 transitions smoothly from front to back, without affecting the forward or reverse conveying of material 1 by the telescopic conveyor 2.

[0042] The material handling device provided in this embodiment of the invention can handle material not only on the first section of the telescopic conveyor, but also at the end of the telescopic conveyor. Figure 10 This is a schematic diagram of the end-feeding process of the inclined conveyor assembly 5 in the extended state of the telescopic conveyor 2, according to the present invention. The end-feeding process of the inclined conveyor assembly 5 in the extended state of the telescopic conveyor 2 is as follows: S21: The ramp conveyor assembly 5 rotates around the second drive shaft 505 in the vertical plane until one end of the ramp conveyor assembly 5 near the telescopic machine 2 rests on the inclined structure B at the front end of the telescopic machine 2. S22: The telescopic conveyor 2 transports material 1 onto the inclined conveyor assembly 5; S23: The telescopic conveyor 2 retracts in the opposite direction of its own conveying direction, and the inclined conveying component 5 moves synchronously with the telescopic conveyor 2 to pick up materials.

[0043] Thus, the inclined conveyor component 5 follows the telescopic conveyor 2 to pick up material at the end of the telescopic conveyor 2, achieving its intended purpose. The material handling device of this invention has both conveying and picking modes, enabling it to adapt to a wider range of operational scenarios.

[0044] Preferably, such as Figure 11 As shown, the two side bars 512 of the inclined conveyor assembly 5 are arranged in a figure-eight shape. This ensures that even if the end of the telescopic conveyor 2 that connects with the inclined conveyor assembly 5 deviates from the inclined conveyor assembly 5 to the left or right, the material 1 can still be picked up smoothly. This increases the docking range of the inclined conveyor assembly 5 and can adapt to a larger range of left and right deviations of the telescopic conveyor end.

[0045] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
