Description

Technical Field

[0001] The utility model relates to the technical field of automatic control of production material transportation, in particular to a multi-layer automatic loading and unloading device. Background Art

[0002] In production, it is often necessary to transport materials and recycle empty boxes after taking materials. In some existing production technologies, most of them are transported by material carts. This method has a low degree of automation and low production efficiency. In addition, because the materials are fed by material carts, the incoming materials and the empty boxes are stacked together. For the staff, it is very inconvenient to take materials and put empty boxes, and it is also very physically demanding to carry materials. In some automated production lines, two conveyor belts are used for loading and empty box recycling respectively. The two conveyor belts are set at both ends of the workstation, which takes up a large space. At the same time, during production, the staff needs to frequently turn their bodies, and when taking materials, the staff also needs to move their bodies to a position where they can observe the materials before taking them. This method affects production efficiency, and when placing empty boxes, they also need to observe before placing the empty boxes. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes a multi-layer automatic loading and unloading device. By designing a rotating mechanism, the carrier for transporting materials can be transferred between the incoming material line and the empty box line, thereby achieving the problem of automatic loading and transferring of empty boxes. The staff only needs to press the switch to control the whole process. An inclined position will also be set at the loading point for the convenience of the staff to take it, thereby reducing the work fatigue of the staff and improving production efficiency.

A buffer seat is arranged below the other end of the inclined surface of the rotating block 213 to buffer the rotating block 213 to prevent the rotating block 213 from being damaged due to excessive force when positioning.

[0069] The positioning mechanism 210 blocks and releases the carrier through the lifting cylinder 212. When the carrier is released in the normal state, the lifting cylinder 212 descends and the roller 214 is flush with the plane of the first material line 200 on the upper surface, so that the carrier can be transported by the roller 214 in cooperation with the second roller 202. In the blocking state, the lifting cylinder 212 pushes up, and the rotating block 213 rotates to the top of the first material line 200 and is higher than the surface of the first material line 200, so that the carrier is blocked from moving forward by the rotating block 213, thereby achieving the effect of box separation.

[0071] Based on Example 3, please refer to Figure 1 This embodiment further optimizes the solution of embodiment 1.

[0072] Among them, the second material line is arranged below the first material line 200, the feeding end and the discharging end of the second material line 300 are arranged obliquely, and the second material line 300 includes a third bracket 310 and a third roller 320; the second material line 300 is arranged with two third brackets 310 in parallel, and a plurality of third rollers 320 are arranged inside the third bracket 310. The second material line 300 is arranged obliquely at the main frame 100 located at the lower part of the first material line 200, and the inclination angle can be controlled according to the actual carrier sliding rate, wherein the upper end of the inclination is the feeding end of the feeding carrier, and the lower end is the discharging end, and the discharging end abuts against the rotating placement component 420 when it is located at the second material position 610, or there is a small gap. The third bracket 310 is arranged on the left and right sides of the second material line 300, and a groove is provided inside the third bracket 310. A plurality of rotating shafts are arranged at intervals in the groove, and a third roller 320 is sleeved on the rotating shaft. A third sensor 540 is fixed on one side of the discharge port of the second material line 300, and the detected state is returned to the control electric box 500. The second material line 300 slides the carrier from the feeding end to the discharging end to realize automatic recovery of empty boxes. The second material line 300 is used to recover the empty boxes that have been taken, thereby realizing automatic recovery of empty boxes.

[0073] Embodiment 5:

[0074] Based on Example 1, please refer to Figures 5 to 7 , this embodiment further optimizes embodiment 1;

[0075] Among them, the electric loading and box return device is mainly composed of three parts: the upper conveyor and blocking device, the lower conveyor and the rotating mechanism. The three parts work together to realize the functions of material sorting, loading, operation and empty box recovery.

[0076] Positioning mechanism 210: Materials are put into the laminar flow channel, and each box of materials is separated by controlling the blocking cylinder to achieve the effect of box separation.

[0077] Transfer mechanism 400: By controlling the extension and retraction of the electric cylinder 411, the rotating storage assembly 420 can be in three states of loading, operation and box return to complete the corresponding operation.

[0078] When the second sensor 530 is triggered by material and the first sensor 520 is not triggered, the lifting cylinder 212 releases the first box carrier; the transfer mechanism 400 reaches the first material position 600, and the carrier slides into the transfer mechanism 400. When the first sensor 520 is triggered, the electric cylinder 411 is triggered to extend and rotate the rotating mechanism to the second material position 610. At the same time, the lifting cylinder 212 resumes the blocking state. The second sensor 530 does not sense the carrier, and the lifting cylinder 212 releases the second box carrier; when the employee completes the material operation in the carrier, he presses the start button on the control switch 510, the electric cylinder 411 is triggered to retract, and the rotating mechanism is rotated to the third material position 620, and the empty carrier that has run out of material is discharged to the lower flow channel. After the third sensor 540 is triggered, the electric cylinder 411 is triggered to extend, and the rotating mechanism returns to the first material position 600.
