Description

Technical Field

[0001] The invention relates to the technical field of copper rod coiling and bundling, and in particular to an automatic copper rod bundling device and an automatic bundling method. Background Art

[0002] At present, after the copper rods are produced by the production line, they pass through the last rolling mill and then are collected and coiled by the rod collecting equipment. Since the copper rods are very sparse after being collected and coiled, it is difficult to lift them. That is, the copper rod coils need to be bundled with three strands of copper rods produced by themselves at intervals of 120° along their circumference. At present, it is operated manually, and it is time-consuming and labor-intensive to manually twist the copper rods, which is very inconvenient. Patent No. CN201811052441.0 discloses a metal coil bundling device and a bundling method, including a bundling trolley, The threading channel, the wire rod cutting mechanism, the traction mechanism, the horizontal hydraulic slide, the inclined hydraulic slide, the vertical motion mechanism and the horizontal motion mechanism arranged on the bundling trolley have a compact structure, can reduce the labor intensity of workers, improve the bundling efficiency, have a high degree of automation, and have firm bundling. However, due to the inconsistent technical requirements for copper rod bundling, it cannot be directly applied to copper rod bundling, and in the process of threading, the threaded coils are easy to cross each other during hoisting, resulting in failure to retract smoothly, resulting in the inability to tighten the coils firmly. Summary of the invention

[0003] The purpose of the present invention is to provide an automatic copper rod bundling device and an automatic bundling method. The two copper rings (binding wires) that have been put on are pressed down obliquely by a certain distance through a wire pressing device, so that the head of the third ring is obviously separated from the copper rings that have been put on. The provided gripper can simultaneously grab the head of the last copper rod and the tail of the first ring. The center line of the main channel is offset by a certain amount relative to the center line of the incoming wire channel to avoid the copper rings that have been put on to cross, so that the braids twisted into the heads and tails of the copper rings cannot be smoothly retracted to tighten the drum reel during the lifting process. The many technical effects that can be produced by the preferred technical scheme among the many technical schemes provided by the present invention are described in detail below.

[0004] In order to achieve the above object, the present invention adopts the following technical solution:

[0005] A copper rod automatic bundling device comprises a fixing frame, a threading channel and a controller, wherein:

[0006] The threading channel includes an inlet channel, a main channel and a secondary channel for guiding the copper rod;

[0007] A traction wheel for traction of the copper rod is provided between the inlet channel and the main channel;

[0008] An encoder for measuring the length of the copper rod is provided at the outlet of the inlet channel;

[0009] A wire pressing device for separating the copper rods is also provided between the traction wheel and the main channel;

[0010] The traction wheel, encoder and wire pressing device are all electrically connected to the controller;

[0011] The threading channel also includes a dividing turntable channel for connecting the main channel and the auxiliary channel;

[0012] The center lines of the main channel and the secondary channel are offset to the left or right by a certain amount relative to the center line of the incoming line channel.

[0015] Optionally or preferably, the secondary channel cooperates with the main channel, and two inner guide wheels and two outer guide wheels are arranged therein, and a secondary channel cylinder for moving the secondary channel mounting frame is arranged in the secondary channel.

[0016] Optionally or preferably, a plurality of guide rollers are provided in the wire inlet channel.

[0017] Optionally or preferably, a gripper for grabbing the copper rod and a shearing device for shearing the copper rod are provided between the traction wheel and the main channel, the gripper and the shearing device are both electrically connected to the controller, and the shearing device and the wire pressing device are both mounted on a fixed frame.

[0018] Based on the above technical solution, the following technical effects can be produced:

[0019] An automatic copper rod bundling device provided by an embodiment of the present invention is suitable for automatic bundling of copper rod coils. The present invention allows the copper rod (bundling wire) to be threaded into a loop through a threading channel, and a traction wheel is used as its traction power. An encoder arranged next to the traction wheel measures the length of the copper rod so as to accurately grasp the timing of starting the wire pressing device and the final length of the wire transmission. An inner guide wheel 1 and an outer guide wheel 1 arranged in the main channel and an inner guide wheel 2 and an outer guide wheel 2 arranged in the secondary channel guide the copper rod. The main channel oil cylinder and the secondary channel oil cylinder are arranged to open the main channel plate and the secondary channel plate to release the copper ring when the gripper lifts the copper ring. The pressure rod extension oil cylinder drives the pressure rod extension slide to move along the threading direction and enter In the threading area, the wire pressing cylinder drives the wire pressing slide to move radially along the copper rod, pressing the two already threaded copper rings diagonally downward for a certain distance, so that the head of the next ring is obviously separated from the already threaded copper ring. The set claw can only grab the head of the last circle of copper rod and the tail of the first circle at the same time. The center line of the set main channel is offset by a certain amount relative to the center line of the threading channel to avoid mutual crossing during the threading process, resulting in the head and tail twisted braids cannot be smoothly retracted to tighten the drum reel during the lifting process, solving the current technical problem of difficult automatic bundling of copper rods.

[0020] The present invention also provides a copper rod automatic bundling method, based on the above copper rod automatic bundling device, comprising the following steps:

[0021] S1 inputs the produced copper rods (bundle wires) along the wire inlet channel;

[0022] S2 The copper rod is pulled into the main channel through the traction wheel, and the encoder beside the traction wheel measures the length of the copper rod at the same time;

[0023] The S3 copper rod passes through the main channel, the indexing turntable channel and the auxiliary channel to form a ring structure;

[0024] After the S4 encoder detects that the copper rod has passed through two circles, it transmits the signal to the controller to start the wire pressing device;

[0025] S5 The pressure rod extension cylinder drives the pressure rod extension slide to move in the threading direction and enter the threading area. The thread pressing cylinder drives the thread pressing slide to move along the radial direction of the copper rod, so that the pressure rod moves the threaded copper ring diagonally downward for a certain distance;

[0026] The S6 copper rod continues to thread. When the encoder detects that the third circle of copper rod leaves the secondary channel and approaches the entrance of the main channel, it transmits a signal to the controller to stop the traction wheel and start the gripper.

[0027] S7 The head of the third copper rod has been clearly separated from the previous two copper rods. After the gripper firmly grasps the head of the third copper rod and the tail of the first copper rod, it transmits a signal to the controller, which starts the shearing device to cut the copper rod between the gripper and the traction wheel;

[0028] S8 opens the main channel oil cylinder and the auxiliary channel oil cylinder at both ends of the main channel and the auxiliary channel, and the gripper lifts the copper rod while cutting it into strands and then releases it;

[0029] S9 rotates the indexing turntable to make the copper rod coil on it rotate 120°;

[0030] S10: Repeat steps S2 to S9 twice to complete three bundling operations;

[0031] S11 Use lifting tools to grab two circles of copper rings at three points at the same time and lift them upwards. The other circle of hinged copper rings can be retracted to coil and tighten the copper rod.

[0032] The invention provides an automatic copper rod bundling method, which meets the technical requirements for copper rod bundling and does not require manual operation, thereby reducing labor costs. BRIEF DESCRIPTION OF THE DRAWINGS
