Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary equipment for steel cord production, and particularly relates to a waste wire treatment device for the bottom of an industrial bobbin. Background Art

[0002] Steel cord, wire rope, etc. are ropes twisted from multiple thin steel wires. In the production process, a wire drawing machine is first used to draw the steel wire through a die into a thin wire with a diameter of 0.15 - 0.3 mm and wind it around an iron industrial bobbin. The industrial bobbin full of steel wire is placed on a stranding machine for wire pay-off, and the stranding machine twists it into a rope. In order to produce products with the required length, and some steel wires will also be wasted during the debugging process, the length of a single steel wire is dozens of meters to hundreds of meters longer than the designed length. Therefore, after the production is completed, a part of the steel wire will remain at the bottom of the industrial bobbin.

[0003] As Figure 13 shown, the traditional method is to manually install the industrial bobbin on the wire pay-off rack and wind the steel wire onto the take-up machine.

Detailed implementation mode

[0039] The present invention will be further illustrated below in conjunction with the accompanying drawings and specific embodiments.

[0040] Embodiment 1: As Figures 1 - 2 shown, a waste wire processing device for the bottom of a spool includes: A conveyor line 1 for conveying the spool 7. The spool 7 with steel wire is conveyed from one side, and the emptied spool 7 is output from the other side.

[0041] An industrial robot 2 for installing and disassembling the spool 7 from the conveyor line 1 onto the rotary wire pay-off rack, and replacing it after confirming that a row of spools is emptied.

[0042] A rotary wire pay-off machine 3. When the industrial robot 2 on one side works to load and unload the spool 7, an operator on the other side unrolls the steel wire from the spool 7 and winds it onto the wire take-up machine 4. When the machine needs to rotate, the operator operates with both hands to stop the robot and make it rotate by indexing.

[0043] For the wire take-up machine 4, the original manual disassembly of the flange 403 is changed to pneumatic disassembly, which is convenient for disassembly and improves efficiency.

[0044] As Figure 3As shown in the figure, the conveyor line 1 is a roller conveyor with its own power, and several motors drive the rotation of a section of rollers respectively. A baffle 101 is provided between two sections of rollers. The I-beam wheel 7 with steel wires coming from the left moves to the baffle 101 and is blocked by the baffle 101. After using the photoelectric sensor to determine that the I-beam wheel 7 is in place, the rotation of the conveyor line 1 is stopped. After the I-beam wheel 7 is taken away, the conveyor line 1 is restarted to move, which is convenient for the industrial robot 2 to grab. The empty I-beam wheel 7 taken from the wire-releasing rack is placed on the right roller path and conveyed to the wet waste workshop for use.

[0045] The industrial robot 2 is a prior art and will not be introduced in detail. As Figure 4 shown, a pneumatic gripper 201 is installed at the end of the axis of the industrial robot 2, and two clamping blocks are installed on the pneumatic gripper 201. When the finger cylinder of the pneumatic gripper 201 acts, the clamping blocks can loosen and clamp the I-beam wheel 7.

[0046] As Figure 5 、 6 、7 shown, the selected divider 302 of the rotary wire-releasing machine 3 is an eight-station divider 302. When the driving shaft 304 rotates one circle, the support shaft 305 rotates 45°. The rotary wire-releasing machine 3 adopts chain 308 transmission, and the driving shaft 304 and the output shaft hole of the divider 302 are fixed and rotate together with the divider 302. There are two driving sprockets 306, which are connected to the driving shaft 304 by a shrink disc and rotate together with the driving shaft 304. The support shaft 305 is fixed on the cabinet and cannot rotate. There are two driven sprockets 307, which are connected to the support shaft 305 through the third bearing.

[0047] When the operator presses the jog button on the first operation panel 314, the motor drives the divider 302 to rotate. The divider 302 drives the driving shaft 304, and the driving shaft 304 drives the driving sprockets 306 on both sides to rotate. The sprockets drive the chains 308 on both sides to move. Each time the divider 302 rotates 45°, it moves one station. When continuously pressing the jog button on the first operation panel 314, it will continue to rotate one station.

[0048] The rotary wire pay-off stand has 16 workstations, and a fixed plate 301 is installed on each workstation. A plurality of spools 7 are installed on the fixed plate 301, and the quantity can be set according to the size of the spools 7. When it rotates to the operating side of the industrial robot 2, a sensor 313 will detect whether the wheel rotates. The spool 7 is installed on the wire pay-off shaft 315, and a high-strength magnet 311 is installed on the end face of the wire pay-off shaft. The spool 7 will be attracted by the magnet 311 onto the wire pay-off shaft 315. The fixed plate 301 has bearing mounting holes, and the wire pay-off shaft 315 and the fixed plate 301 are connected together through a first bearing 309. A metal piece 312 is welded on the shaft end cover 310. When pulling the residual wire on the spool 7, it rotates together with the wire pay-off shaft 315 and the spool 7. When it rotates to the position of the sensor 313, the sensor 313 switch acts. By this sensor 313, it is judged whether the wheel rotates, and the PLC controller will know whether the residual wire on the spool 7 has been pulled out.

[0049] As Figure 8 、 9 、10, 11 show, the flange 403 is fixed on the take-up reel after being tightened by the locking block 410. There is an oblong hole 411 in the middle of the flange 403, which has the same size as the locking block 410. After the locking block 410 passes through the oblong hole 411, the flange 403 rotates 90°, and when the locking block 410 falls into the card slot 412 of the flange 403, it is tightened and fixed. The support rod 405 is connected to the main shaft 402 through a connecting rod 408, and six sets of such structures are evenly distributed around. The bearing seat 406 is used to install three second bearings 407, and the second bearings 407 are fixed on the main shaft 402 using locking nuts. A driven pulley A416 is installed on the main shaft 402, and the driven pulley A416 is fixed on the main shaft 402 using a shrink disc. In the center of the main shaft 402, there is a through stepped hole. A pull rod 404 is installed in the stepped hole, and 35 disc springs 409 are installed in the middle of the pull rod 404. The left end of the pull rod 404 is threadedly connected with the locking block 410, and there is a lifting cylinder 413 on the right side of the main shaft 402, which can push the pull rod 404 to move.

[0050] Working principle of the take-up reel: When the wire is wound full on the take-up reel, the wire on it needs to be removed. First, the lifting cylinder 413 acts, pushing the pull rod 404 to move to the left. The pull rod 404 overcomes the thrust of the disc spring 409, pushing the locking block 410 to move to the left, and the locking block 410 and the flange 403 are loosened. Manually operate the flange 403 to rotate 90°, align with the oblong hole 411, and the flange 403 can be removed. Since there is no pressing of the flange 403, the support rod 405 becomes in a free state, the bottom diameter of the take-up reel will become loose, and a simple tool or bare hands can be used to remove the wire wound on the take-up reel. Using the same operation method, install the flange 403 onto the take-up reel, and the cylinder retracts. Under the thrust of the disc spring 409, the pull rod 404 moves to the right, pulling the locking block 410 to tighten the flange 403.

[0051] As Figure 12 shown, the wire arranging device uses a servo motor 419 or a stepper motor as the wire arranging motor, and the servo motor 419 is fixed on the support 418. The linear guide 423 is fixed on the support 418, and the slider 424 can move linearly on the linear guide 423. One end of the wire arranging rod 425 is fixed on the slider 424, and a wire arranging guide wheel 426 is installed at the other end. The linear bearing 427 plays a supporting role. A synchronous belt B422 is installed on the driving pulley B420 and the driven pulley B421. The servo motor 419 drives the synchronous belt B422 to move, and the synchronous belt B422 is fixed on the slider 424 using clip pieces. The synchronous belt B422 can drive the slider 424, the wire arranging rod 425, and the wire arranging guide wheel 426 to move along the direction of the linear guide 423 together. There are three proximity switches 429 in total. The middle one is the zero position, and the two on both sides are the limit positions. The detection piece 428 lights up as the zero point. The number of pulses for left and right movement is set to control the wire arranging distance on both sides. When the detection piece 428 detects the proximity switches 429 on both sides, the machine will alarm and stop.

[0052] The specific working principle of the present invention is as follows: The spool 7 with residual steel wires transported from the stranding workshop is transported through a roller conveyor. When it moves to the position of the baffle 101, it is blocked. The photoelectric sensor detects that the wheel is in place, and the conveyor line 1 stops transporting. The industrial robot 2 will clamp the spool 7 through the pneumatic gripper 201. The photoelectric switch detects that the spool 7 has been taken away, and the roller conveyor continues to operate. The industrial robot 2 installs the spool 7 with steel wires on the pay-off shaft 315 of the rotary pay-off stand, removes the empty spool 7 on the pay-off shaft 315, and places it behind the baffle 101 of the conveyor line 1. On the working side of the industrial robot 2 of the rotary pay-off machine 3, there is a sensor 313 for confirming whether each spool 7 rotates behind each spool 7. Only when it is detected that all the spools 7 at a working station stop rotating, will the industrial robot 2 choose to replace the spool 7.

[0053] The worker stands in front of the equipment, unties the steel wire from the spool 7, passes it through the wire collecting ring 6, bypasses the wire arranging wheel of the take-up machine 4, and then winds it around the take-up reel of the take-up machine 4. Start the take-up machine 4, and the steel wire will be pulled out from the spool 7 and concentrated on the take-up reel. After processing the wheels at a working station, the worker presses two buttons on the first operation panel 314 with both hands at the same time, and the industrial robot 2 stops working. After the industrial robot 2 completes an action, it returns to the zero position. The rotary pay-off stand starts to rotate, rotating one working station each time. When the rotary pay-off stand starts to rotate and the button is released before a working station is completed, the rotary pay-off stand rotates one working station and then stops. If the button is not released when it rotates in place, it will continue to rotate continuously. It will stop until the button is released, and after stopping for 5 seconds, the industrial robot 2 gets permission to continue working.

[0054] The wire take-up machine 4 evenly winds the steel wire onto the wire take-up reel through the movement of the wire arranging wheel. When the wire take-up reel is full, the wire take-up machine 4 is stopped, and the industrial robot 2 returns to the zero point. The flange 403 in front of the wire take-up reel is unlocked through the lifting cylinder 413, and the steel wire is removed from the wire take-up reel.

[0055] The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and cannot be used to limit the protection scope of the present invention. Any equivalent transformation or modification made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
