Description

TECHNICAL FIELD

[0001] The present application relates to a stacking device and its application. BACKGROUND

[0002] The slitting machine is a pre-press and post-press equipment for cutting a large roll of paper, film, non-woven fabric, aluminum foil, mica tape, prepreg and other thin materials into small rolls of different widths, commonly used in paper machinery, printing and packaging machinery and PCB industry.

[0003] In the copper-clad plate industry, the slitting machine is a very important link, which can liberate the winding link and directly enter the cutting operation, greatly saving production time and improving use efficiency, so it is also called a continuous cutting machine in the PCB industry.

[0004] In the prior art, a conveying device and a stacking device are provided behind the continuous cutting machine, the conveying device conveys the sheet material with a certain length cut by the continuous cutting machine to the stacking device, so as to realize the accumulation of the sheet material on the stacking device. However, the stacking device used with the continuous cutting machine in the prior art also has many defects, which are as follows: 1. Since the conveying belt fluctuates greatly during movement, the friction between the sheet material and the conveying belt is not enough during conveying, so it is often impossible to convey the sheet material in place, and an operator must be beside the stacking device at all times to sort and arrange the sheet material; 2. The existing stacking device is provided with a stop block on one side along the conveying direction and on the side away from the conveying device perpendicular to the conveying direction, for limiting the movement of the sheet material, but the operator needs to move his own work station to raise the stop block; 3. Compared with other high-speed machines, the running speed of the continuous cutting machine is relatively low, but it is slightly fast for the operator, who often cannot keep up with the cutting speed of the continuous cutting machine, and cannot stack the cut sheet material neatly, and the operation is highly repetitive, so the operator is more likely to suffer from mechanical fatigue; 4. The hydraulic table cannot work automatically, and the operator needs to manually adjust the height, which further increases the difficulty of stacking the sheet material neatly. However, if the sheet material is not stacked neatly, the sheet material will be delayed in the next process, thereby greatly reducing the production efficiency. SUMMARY

[0005] The technical problem to be solved by the present application is to overcome the defect that the existing stacking device cannot stack the sheet material conveyed by the conveying device neatly on the carrying table, and to provide a stacking device for stacking sheet material, which can automatically stack the sheet material neatly on the carrying table, reduce the labor intensity of the work station, improve the work efficiency and safety factor of the work station, and avoid delaying the next process.

[0006] The present application solves the above technical problems by the following technical solutions:

[0007] The present application provides a stacking device, which comprises a bearing table and a aligning device, the aligning device comprises first stoppers and second stoppers, the first stoppers are located on both sides of the bearing table along the conveying direction, and the second stoppers are located on the side of the bearing table which is far away from the conveying device and perpendicular to the conveying direction. The aligning device is used to limit the movement of the sheet material on the bearing table to make it stack neatly.

[0008] In the present application, preferably, the aligning device further comprises a telescopic mechanism connected with the first stoppers. The telescopic mechanism is preferably a pneumatic cylinder. After the telescopic mechanism is started, the telescopic mechanism drives the first stoppers to move away from the sheet material first, and then move close to the sheet material again, and so on, so that better neat stacking can be achieved.

[0009] In the present application, preferably, the aligning device is further provided with a handle, and the handle is used to adjust the minimum distance between the first stoppers. When the width of the sheet material changes, the handle can adjust the minimum distance between the first stoppers, so that the adaptability of the stacking device can be further improved.

[0010] In the present application, the first stoppers and / or the second stoppers are preferably steel plates, and more preferably stainless steel plates. The thickness of the first stoppers and / or the second stoppers is preferably 3mm.

[0011] In the present application, preferably, the stacking device is further provided with a PLC controller, a positioning device and / or a counter.

[0012] The positioning device cooperates with the PLC controller to control the height of the bearing table. Preferably, the positioning device makes the height of the sheet material on the bearing table not higher than the horizontal height of the conveying belt. More preferably, the positioning device keeps the height of the sheet material on the bearing table at a position substantially flush with the conveying belt. The positioning device preferably comprises a photoelectric switch, and the difference between the high position and the low position of the photoelectric switch is adjusted according to the thickness of the sheet material. The difference between the high position and the low position of the photoelectric switch is preferably the thickness of one sheet of the sheet material, for example, 2cm. When the height of the sheet material on the bearing table reaches or exceeds the high position of the photoelectric switch, the PLC controller controls the bearing table to descend, so that the height of the sheet material on the bearing table reaches or is lower than the low position of the photoelectric switch.

[0013] The counter is preferably arranged below the bearing table and is used to record the number of sheet materials. The counter can also cooperate with the PLC controller to control the start of the telescopic mechanism. When the counter reaches a set base number, the PLC controller starts the telescopic mechanism. The base number is set according to the material and thickness of the sheet material, for example, 10.

[0014] The PLC controller can also control the telescopic distance of the telescopic mechanism. The telescopic distance refers to the distance that the first stop block needs to move from the minimum distance to the maximum distance.

[0015] In the present application, the bearing table is preferably a hydraulic table, such as an oil hydraulic table.

[0016] The present application also provides an application of the stacking device in stacking sheet materials. The sheet materials can be conventional sheet materials in the art, preferably one or more of paper, film, non-woven fabric, aluminum foil, mica tape, and prepreg.

[0017] The positive progress effect of the present application is that the present application provides a stacking device. Compared with the existing stacking device, the stacking device of the present application can realize the stacking of sheet materials in order by arranging a flattening device, especially using a cylinder to perform flattening work. Further, by arranging a positioning device, a counter, a PLC controller, etc., automatic control of the lifting of the bearing table, the start of the flattening device, etc. is realized. The stacking device of the present application is used for stacking sheet materials, is convenient to use, can reduce the labor intensity of the work station, improve the operation efficiency of the work station, improve the safety factor, and avoid causing delay in the next process.
