Please refer to Figures 1 to 3, the utility model sheet coil material automatic refueling mechanism 10 includes: refueling actuators located on the left and right sides and oppositely arranged, and a discharge detection sensor 1 for detecting whether the material is about to end Each refueling executive device includes a material carrying plate 2, a roller fixing frame 3, a refueling roller 4 connected to the roller fixing frame 3, a driving device 5 that pushes the refueling roller 4 to move left and right, and is located at the The cutter device 6 below the material roller 4, the material pressing device 7 above the material carrying plate 2, the material preparation detection sensor 8 for detecting the state of material preparation, and the drive device between the roller fixing frame 3 and the material carrying plate 2 5 connection, the refueling rollers 4 of the two refueling actuators are set opposite to each other, the material preparation detection sensor 8 is located above the material carrying plate 2, and the discharge detection sensor 1 is located at the outlet of the refueling roller 4. The discharge detection sensor 1 and the stock detection sensor 8 are reflective sensors or through-beam sensors.

The driving device 5 is an air cylinder or a motor, and the roller fixing frame 3 and the material carrying plate 2 are slidably connected through a roller guide mechanism 9 .

The cutter device 6 includes a cutter cylinder 61 arranged on the material carrying plate 2, a refueling cutter 62 arranged at the output end of the cutter cylinder 61, a cutter baffle plate 63, and a cutter guide mechanism 64. The cutter cylinder 61 passes through the The cutter baffle 63 is arranged on the material carrying plate 2 , and the refueling cutter 62 is slidably connected to the cutter baffle 63 through a cutter guide mechanism 64 . The refueling cutter 62 is a bevel cutter, a sawtooth cutter or a mobile cutter fixed on the rodless cylinder.

As shown in Figure 1, in the process of automatic refueling, it is only necessary to make a simple mark on the position of the material before it is used up or directly reserve a section of material that is different from the normal material. When the discharge detection sensor 1 detects that the material When the signal ends, the signal is transmitted to the PLC, and the driving devices 5 of the two refueling actuators respectively drive the two refueling rollers 4 to clamp the two pieces of material, and then the left side cutter device 6 cuts off the left material 50, and the two refueling rollers The wheel 4 is slowly reversed along with the material until the double-sided adhesive 11 glues the left material 50 and the right material 60 together, then the left material change roller 4 is retracted, and the right material change roller 4 remains extended. , the automatic refueling is completed.

As shown in Figure 2, assuming that the material on the left scroll material hanging shaft 20 will be used up at this time, and the material to be changed has been loaded on the right coil material hanging shaft 30, the specific refueling process action is: on the left hanging scroll During the normal unwinding process, when the discharge detection sensor 1 detects the end signal of the material (such as uncoated copper foil, aluminum foil on the cathode and anode of the continuous coating film, or a special end marker attached to the surface of the material), the signal is transmitted To PLC, inform the material on the left scroll material hanging shaft 20 to be used up soon, need refueling, then PLC sends the command of pause action and shows that material will be finished, needs refueling. If the right side material preparation detection sensor 8 detects that the material to be changed on the right coil material hanging shaft 30 is ready at this time, then the PLC sends an instruction, and after the left coil material hanging shaft 20 continues to unwind for a certain length, the left coil material hanging shaft 20 is terminated. action, and open the action function of the right material hanging scroll 30. At the same time, the right driving device 5 acts to promote the right material changing roller 4 to move forward.

The fixing and pressing effect. When the right material 60 compresses the cylinder 71 and returns to the end, give the PLC a signal to complete the return, and the PLC sends an instruction to allow the right coil material hanging shaft 30 to slowly rewind a certain distance ( This distance is enough to guarantee that left material 50 and right material 60 stick together), then left material changing roller 4 returns. When the left refueling roller 4 returns to the left limit position, a signal is given to the PLC to inform the PLC that the refueling has ended and the whole system can continue to operate, then the PLC sends an instruction to continue the normal linkage of the system. At this time, the automatic refueling is completed, and the total time does not exceed 30s. And the action principle that the right coil material hanging shaft 30 is automatically changed to the left coil material hanging shaft 20 is the same.

As shown in FIG. 3 , the automatic refueling mechanism 10 is a small part of the entire winding system, and the matching mechanism includes a left coil hanging shaft 20 , a right coil hanging shaft 30 and a set of tension control system 40 . Before automatic refilling, that is, after the discharge detection sensor 1 detects that the material of the left coil hanging shaft 20 in normal use is about to end, the left coil hanging shaft 20 needs to slowly release a certain length of material first, so that the tension control system 40 The pendulum roller is near its maximum length, so as to offset the influence of the length of the right roll material hanging shaft 30 rewinding on the tension control system 40 and the material in the automatic roll changing process. It can be seen that the process of automatic refueling is a process of mutual cooperation between the tension control system 40 , the left coil hanging shaft 20 , the right coil hanging shaft 30 and the automatic material changing mechanism 10 .
