Description

Technical Field

[0001] This invention relates to the field of production line equipment technology, and in particular to a transport protection device for the unloading area. Background Technology

[0002] In automated material handling and processing production lines, the cycle time matching and fault isolation capabilities between upstream and downstream equipment are key factors affecting the overall line operating efficiency. To ensure continuous production, conveyor belts are often used in conjunction with moving slides to achieve automatic material transfer between different workstations. However, when downstream processing equipment is temporarily shut down due to malfunctions, maintenance, or other reasons, if upstream materials cannot be diverted or temporarily stored in a timely manner, the main conveyor belt will be forced to stop supplying materials, causing the entire production line to be interrupted and severely impacting capacity and equipment utilization. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a transport protection device for the unloading area. By switching the slide assembly between the main conveyor belt and the buffer conveyor belt, the material is automatically buffered when the next process is abnormal, and automatically cuts back after the normal operation is restored, thereby ensuring the continuous operation of the entire production line and improving production efficiency and system anti-interference capability.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a transport protection device for a material unloading area, including a conveyor belt assembly, a slide assembly and a worktable. The conveyor belt assembly and the slide assembly are fixed on the worktable. The conveyor belt assembly includes a main conveyor belt and multiple buffer conveyor belts. A transfer component is fixed on the slide assembly. The transfer component is connected to the conveyor belt assembly. The transfer component is used to transfer the material on the main conveyor belt to the buffer conveyor belt or the next process.

[0005] Furthermore, the main conveyor belt is fixed to the workbench by a first support frame, and a first counting sensor is installed on the main conveyor belt. The first counting sensor is used to record the quantity of material passing through the main conveyor belt.

[0006] Furthermore, the buffer conveyor belts are distributed on the left and right sides of the main conveyor belt and are parallel to the main conveyor belt. The buffer conveyor belts are fixed to the workbench by the second support frame. A second counting sensor is installed on the main conveyor belt. The second counting sensor is used to detect the material arrival signal.

[0007] Furthermore, the slide assembly includes a first slide, a second slide, and a slide rail assembly. The slide rail assembly includes a first lead screw, a second lead screw, and a slide rail. The slide rail is fixed to the worktable. The first lead screw is fixed to the worktable and has a first nut screwed onto it. The first slide is fixed to the first nut and is slidably connected to the slide rail. The second lead screw is fixed to the worktable and has a second nut screwed onto it. The second slide is fixed to the second nut and is slidably connected to the slide rail.

[0008] Furthermore, the transfer assembly includes a transfer conveyor belt, which is fixed to the first slide and the second slide respectively by a third support frame.

[0009] Compared with the prior art, the advantage of this invention is that the slide assembly drives the transfer conveyor belt to flexibly switch and connect between the main conveyor belt and multiple buffer conveyor belts. When the next process fails or is blocked, the slide assembly can automatically switch to the buffer conveyor belt to temporarily store materials, avoiding the main conveyor belt from being forced to stop. After the next process returns to normal, the slide assembly automatically switches back to the main conveyor belt to continue feeding materials to the next process, ensuring that the previous production is not interrupted due to the subsequent temporary abnormality, and effectively ensuring the continuous operation of the entire production line.

Detailed Implementation

[0011] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0012] like Figures 1 to 5As shown, a transport protection device for a material unloading area includes a conveyor belt assembly 1, a slide assembly 2, and a worktable 3. The conveyor belt assembly 1 and the slide assembly 2 are fixed on the worktable 3. The conveyor belt assembly 1 includes a main conveyor belt 11 and multiple buffer conveyor belts 12. The main conveyor belt 11 is fixed to the worktable 3 by a first support frame 13. A first counting sensor 14 is installed on the main conveyor belt 11 to record the quantity of material passing through the main conveyor belt 11. When the accumulated quantity reaches a preset value of the control system, the control system controls the main conveyor belt 11 to temporarily suspend feeding, and resumes operation after receiving the next start trigger signal. The buffer conveyor belts 12 are distributed on the left and right sides of the main conveyor belt 11 and are parallel to the main conveyor belt 11. The buffer conveyor belts 12 are fixed to the worktable 3 by a second support frame 15. A second counting sensor 16 is installed on the main conveyor belt 11 to detect the material arrival signal. When the material is detected, a trigger command is generated as a judgment signal to start the movement of the slide assembly 2 and to start the transfer assembly 4 to transfer the material. A transfer assembly 4 is fixed on the slide assembly 2. Component 4, the slide assembly 2 includes a first slide 21, a second slide 22, and a slide rail assembly. The slide rail assembly includes a first lead screw 23, a second lead screw 24, and a slide rail 25. The slide rail 25 is fixed on the worktable 3. The first lead screw 23 is fixed on the worktable 3, and a first nut 231 is screwed onto the first lead screw 23. The first slide 21 is fixed to the first nut 231, and the first slide 21 and the slide rail 25 are slidably connected. The second lead screw 24 is fixed on the worktable 3, and a second nut 241 is screwed onto the second lead screw 24. The second slide 22 and the second nut 241 are slidably connected. 241 is fixed, the second slide 22 is slidably connected to the slide rail 25, the first slide 21 and the second slide 22 are driven independently by the first lead screw 23 and the second lead screw 24 respectively, the movement strokes are independent of each other, they can move independently and do not interfere with each other, the transfer component 4 is connected to the conveyor belt component 1, the transfer component 4 is used to transfer the material on the main conveyor belt 11 to the buffer conveyor belt 12 or the next process, the transfer component 4 includes a transfer conveyor belt 41, the transfer conveyor belt 41 is fixed to the first slide 21 and the second slide 22 respectively by the third support frame 42.

[0013] The usage process of this embodiment is as follows: The control system controls the first lead screw 23 to rotate, driving the first nut 231 to move the first slide table 21 along the slide rail 25 to the docking position with the main conveyor belt 11. The material on the main conveyor belt 11 is received by the transfer conveyor belt 41 on the first slide table 21. The first counting sensor 14 counts. When the material is full, the first slide table 21 stops picking up material and moves along the slide rail 25 to the receiving port of the next process. The transfer conveyor belt 41 unloads the material and sends it to the next process for processing. After the first slide table 21 leaves the main conveyor belt 11, the control system controls the second lead screw 24 to drive the second slide table 22 to move along the same slide rail 25 to the docking position of the main conveyor belt 11 to start picking up material and transferring it to the receiving port of the next process. The two slide tables alternate in this cycle to maintain continuous material supply to the main conveyor belt. The two material-adhesive machines process in parallel to achieve efficient continuous production. When a fault occurs in the next process, a fault signal is issued. Upon reaching the control system, after the first slide 21 is full of material, the control system drives the first slide 21 to move to the corresponding position on the buffer conveyor belt 12 and store the material in the buffer conveyor belt 12. During the fault, the first slide 21 continuously picks up material from the main conveyor belt 11 and stores it into each buffer conveyor belt 12 in sequence. If the fault is temporarily resolved and then triggered again, the slide continues to replenish and store material based on the original buffer storage, without needing to clear the buffer and start again. If the buffer conveyor belt 12 is completely full, the control system issues a shutdown alarm signal, and the entire line is shut down to prevent material accumulation. After the fault is resolved, the operator presses the reset button, and the control system immediately switches back to normal mode. Regardless of how much material is stored in the buffer conveyor belt 12 (as long as it is not full), the first slide 21 resumes docking with the main conveyor belt 11 to pick up material and send it to the receiving port of the next process, restoring normal production. The material remaining in the buffer conveyor belt 12 is consumed later when the main conveyor belt 11 is empty.

[0014] The control system in this embodiment uses existing technology.
