[0002] In the copper rod processing process, it needs to go through two processes: extrusion and cutting. During the cutting process, we hope to get copper rods of equal length and then pack them. The existing operation method is to mark the distance with a marker pen behind the cutting machine, and the employees visually or manually align it. After alignment, the iron plate between the rollers is lifted, and the copper rod is rolled onto the rack by gravity and the operator's hook. Because there is a certain height difference between the height at which the copper rod is lifted and the stacking plane of the rack, the end of the copper rod will hit the surface of the copper rod after rolling, and a small pit will be knocked out; sometimes, some copper rods are offset and not lifted, and the copper rod is bent when the iron plate returns. Not only can the rods not be aligned, but the unloading also requires manual intervention, which is inefficient and greatly affects product quality. Summary of the invention

[0029] The working principle of the above-mentioned copper alloy bar automatic stacking machine is as follows: before the bar cutting work is carried out, the third motor 56 drives the worm gear reducer 57, and then drives the transmission gear 54 and the rack 55 to rotate, so that the sliding platform 5 is translated to the specified position away from the cutting machine side through the guide rail 52 according to the length requirement of the product, and then the second cylinder 58 drives the baffle 51 to descend to face the bar transfer area 13; then, under the simultaneous drive of the 14 first motors 27, the first chain 23 drives and drives the double-row sprocket 22 to rotate, and then drives the second chain 26 to drive, and the roller 21 has both the discharge and transfer functions, so as to realize the transportation of the bar from the entrance side of the bar conveying mechanism to the bar transfer area 13. When the head of the bar contacts the baffle 51, the automatic head alignment of the bar is completed, and the 14 first motors 27 stop working; thereafter , the cutting machine cuts the bar material.

When the detection mechanism detects the height of the bar material, the detection mechanism sends a signal to the control system to move the cylindrical rack 41 backward and reset. During the backward movement of the cylindrical rack 41, the last bar material on the cylindrical rack 41 contacts the material blocking column 14. As the cylindrical rack 41 continues to move backward, the bars on the cylindrical rack 41 fall one by one from the front side of the cylindrical rack 41 onto the storage mechanism. This cycle is repeated until the number of bars stacked on the storage mechanism is sufficient, and they are packaged and stored.

[0030] The entire working process of the above-mentioned copper alloy bar automatic stacking machine has a high degree of automation.
