Description

Technical Field

[0001] This invention belongs to the field of material destacking and circulation, especially destacking and packaging equipment for sintered bricks. Background Technology

[0002] The sintered brick industry is a large, traditional industry with a lot of heavy manual labor. Among them, the unstacking of sintered bricks is a physically demanding process that is difficult to automate or unmanned. The main reason is that the sintered bricks and brick stacks will have significant deformation. Some brick stacks are as high as 2 meters and contain hundreds of bricks. The brick stacks will have uncertain deformations such as tilting and twisting. Under the uniform program control, robotic arms, including robotic grippers, cannot correspond to each layer of bricks with different deformation. Current unstacking machines can only be operated with a lot of manual intervention and position adjustment to barely achieve semi-automatic unstacking. There are many pauses and the efficiency is very low. Summary of the Invention

[0003] This invention provides a fully automated destacking device that can pre-sort brick stacks, avoiding the impact of brick stack deformation on the robotic arm's gripping, and achieving smooth operation.

[0004] In addition to the gripping machinery, brick conveying line, palletizing machinery, and baling machine, the automatic destacking system of this invention also includes a stack shaping machine. The stack shaping machine is positioned above the brick stack to be destacking on the brick stack transfer line. As the brick stack moves with the transfer line to below the stacking machine, the stack shaping machine supports and straightens any deformed or skewed layers of the stack to be destacking, restoring the stack to a relatively regular shape and position, facilitating quick gripping by the destacking gripper. The gripping machinery (e.g., a destacking robot) with destacking grippers and the brick conveying line are located on one side of the stack shaping machine to perform the destacking work. The destacking gripper gathers and grips the top layer of bricks from the stack to be destacking, then transfers them to the brick conveying line. After being gathered and arranged into a suitable brick array for stacking, the stacking and baling operations are performed by the palletizing and baling machines located at the output end of the brick conveying line, bundling the bricks into bundles for easy transport.

[0005] More specifically, the aforementioned stacking sorting machine includes: a frame, a liftable frame mounted on the frame, clamping plates arranged on multiple sides of the frame, a clamping and guiding device for the clamping plates, and a power device for driving the clamping plates. The power device can be a pneumatic cylinder, a hydraulic cylinder, a motor, or a spring. During operation, the lifting frame reaches the desired stack height and fits onto the brick stack. The clamping plates enter the gaps between the brick stacks, and the power device drives the clamping plates, pushing the bricks to their original predetermined positions to correct and eliminate deformation.

[0006] This stacking machine can also push and clamp the lower layer of bricks in the stack to be grabbed, correcting deformation while maintaining the stability of the stack, counteracting the shaking caused by the robotic arm when grabbing the bricks, and preventing the bricks from falling over.

[0007] This automated destacking and packing system uses a stack sorting machine to pre-align and sort the brick stacks, ensuring that the top layer of bricks to be grabbed returns to the predetermined grab position. This avoids interference with the grabber caused by the stack tilting or shifting beyond the predetermined range. Once the programmable robotic arm or robot with the grabber is in place, it can accurately, smoothly, and quickly grab the bricks without the need for manual intervention, reducing labor intensity and greatly improving destacking efficiency.

[0008] This invention can also be used for the dismantling of steam-cured blocks, pressed bricks and other products. Attached Figure Description

[0010] Appendix Figure 2 This is a simplified schematic diagram of a partial structure of the present invention. Detailed Implementation

[0011] The present invention will now be described in further detail with reference to the accompanying drawings. Example 1

[0012] like Figure 1 , Figure 2 As shown, there are multiple rectangular stacks 1 of sintered bricks on the kiln car 2 that transports the brick stacks. Each small brick stack has gaps around its perimeter for ventilation during firing. A stack-shaping machine 3 is installed across the kiln car and the brick stacks to correct the stack shape. The frame of the stack-shaping machine 3 contains a stack-shaping frame 4 that can be raised and lowered. Multiple small frames are distributed according to the stack position within the stack-shaping frame. Each small frame corresponds to one small sintered brick stack. Four clamping plates 41, 44, 47, and 48 are arranged in a staggered manner on the four sides of the stack shape. Each clamping plate has two guide rods and two cylinders as reciprocating guides and reciprocating power. The cylinders push and pull the clamping plates to clamp and straighten the brick stacks. The clamping plate 41 is fixed to two guide rods 42. One end of the guide rod 42 is slidably fitted on one side of the stacking frame 4, and the other end is connected to a cylinder 43 fixed on another side of the stacking frame. The clamping plate 44 is slidably fitted on the side of the stacking frame through two guide rods 45. The clamping plate is also connected to two cylinders fixed on the side of the stacking frame. The clamping plates 47 and 48 are each supported by two cylinders 46 fixed on the stacking frame. The cylinder rods simultaneously play the role of maintaining the position and guiding the movement of the clamping plates.

[0013] When the brick stack moves with the kiln car to a stop under the stack sorting machine, the stack frame 4 descends. The frame and the clamps on the four sides of each smaller frame then descend into the gaps between the brick stacks until they reach the next layer of the stack to be sorted, fitting onto the stack. Clamps 41, 44, 47, and 48, driven by cylinders, move towards the brick stack, pushing any bricks that have tilted beyond their predetermined positions back to their correct locations, correcting and eliminating any tilting or deformation of the layer to be sorted. After the stacking robot removes the top layer of bricks, the clamps, driven by cylinders, release the stack, and the stack frame 4 moves down, repeating the above actions to sort the next layer of bricks.

[0014] The stacking sorting machine 3 is equipped with a destacking robot 6 and a brick conveying line 6 on one side. The brick conveying line is responsible for grouping, sorting and conveying the bricks brought by the destacking robot. The output end of the brick conveying line is equipped with a palletizing robot 7 and an automatic bundling and packaging line 8.

[0015] The destacking robot 5 gathers and grabs the top layer of bricks that have been arranged in the brick stack, and places them at the designated position on the brick conveyor line 6. The brick conveyor line arranges the bricks into a square according to the stacking requirements, and then transports them to the palletizing robot 7 for grabbing. After that, the bricks are stacked on the automatic bundling and packaging line 8. The brick stacks stacked on the packaging line are finally bundled and packaged to form a stack that is easy to transport.

[0016] In this way, because the stack sorting machine pre-aligns and sorts the brick stacks, keeping them stable and the bricks neatly and uniformly positioned, it ensures that the destabilizing robot can quickly and accurately grab the bricks, avoiding interference between the gripper and the stack, and also avoiding the waste of time for manual intervention to align the robotic arm with the stack position. This greatly reduces the workload and significantly improves the destabilizing efficiency.

The descriptions of the above embodiments are only for the purpose of helping to understand the core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
