Description

Technical Field

[0001] This utility model relates to a wire end finding device for a winding machine, belonging to the field of winding machinery technology. Background Technology

[0002] A winding machine is a device that winds thread-like objects onto a spool. When a spool is full, it needs to be cut and replaced. The new spool has some thread left over, with the thread ends outside the spool. The thread ends need to be found on the spool using a thread end finding device, and then the thread to be wound is welded to the thread ends on the empty spool using a welding device before the new winding begins.

[0003] There are many types of existing wire end finding devices, such as the Chinese authorized utility model patent with authorization announcement number CN213201930U, entitled "An Automatic Wire End Finding Device." This patent is a previous technical solution of our company. In use, a certain length of wire end protrudes from the wire spool on the electric turntable. The pneumatic cylinder extends, driving the fixed plate and the device on it to move, so that the gripper cylinder moves to the edge of the wire spool. The gripper cylinder opens the gripper, and the electric turntable drives the wire spool to rotate. When the wire end in the wire spool rotates to the vicinity of the photoelectric sensor in front of the gripper, the photoelectric sensor senses the wire and the air column starts blowing air. The high-pressure airflow blows the wire into the closed area of ​​the gripper in a predetermined direction. The gripper cylinder clamps the gripper. After the wire end is clamped, the pneumatic cylinder retracts, pulling the wire end to the required position. The guide rod can prevent the fixed plate from shaking when the pneumatic cylinder extends and retracts, increasing the accuracy of the gripper clamping the wire.

[0004] While the above structure can also locate the wire ends, it presents the following problems in practical use:

[0005] 1. In the existing technology, multiple air columns are set up. The existing air columns are generally set on the outside of the wire spool. The air columns blow air to lift the wire ends on the empty wire spool. However, in actual use, the wire ends often get tangled on the electric turntable during the blowing process, making it difficult to clamp the wire ends later and causing the problem of wire end retrieval failure.

[0006] 2. After the existing wire reel is placed on the electric turntable, it is usually fixed to the electric turntable with multiple bolts in order to secure the wire reel. Although the above-mentioned bolt fixing method can achieve the purpose of fixing, it is relatively troublesome to install and disassemble, resulting in low work efficiency. Summary of the Invention

[0007] The technical problem to be solved by this utility model is to provide a wire end finding device for winding machines, so as to solve the problem faced in the industry.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a wire end finding device for a winding machine, comprising a base, with multiple sets of wire end finding devices arranged on the upper surface of the base, each wire end finding device including a wire end clamping device and a wire spool fixing structure, the wire spool fixing structure including a rotary motor mounted below the base via a motor frame, a transition rotary shaft arranged on the motor shaft of the rotary motor, the transition rotary shaft passing through the lower surface to the upper surface of the base, a wire spool placement seat arranged on the top of the transition rotary shaft, a wire spool placed on the wire spool placement seat, and an anti-tangle air blowing seat sleeved on the wire spool placement seat.

[0009] Preferably, the coil placement seat includes a placement seat body, a coil positioning seat is provided on the top of the placement seat body, an inner groove is provided in the middle of the bottom of the placement seat body, a connecting shaft insertion hole is provided on the top of the inner side of the inner groove, and an upper bolt through hole is provided on the top of the coil positioning seat, the upper bolt through hole extending from the top of the placement seat body into the connecting shaft insertion hole.

[0010] Preferably, the side of the spool positioning seat is provided with a horizontal spool placement platform, and the upper surface of the spool placement platform is provided with a magnet placement groove, in which an adsorption magnet is placed.

[0011] Preferably, the transition rotating shaft is inserted into the connecting shaft insertion hole, and the top of the transition rotating shaft is provided with a connecting threaded hole, which is coaxial with the upper bolt through hole.

[0012] Preferably, the anti-tangle blowing seat includes a cylindrical body with a circular structure, a plurality of vertical blowing holes are provided on the cylindrical body, the vertical blowing holes extend from the bottom of the cylindrical body to the upper surface, the base is provided with a plurality of gas transition holes, the gas transition holes are coaxially arranged with the vertical blowing holes, and an air inlet pipe is provided at the bottom of the gas transition holes.

[0013] Preferably, the motor frame includes multiple motor connection transition plates, which are connected to the rotary motor. Multiple connecting support columns are provided on the motor connection transition plates, with one end of each column fixed to the motor connection transition plate and the other end connected to the base.

[0014] Preferably, the wire clamping device includes a clamping moving cylinder, wherein a double-axis clamping cylinder is provided on the cylinder shaft of the clamping moving cylinder, and a gripper is provided on the cylinder shaft of the double-axis clamping cylinder.

[0015] Compared with the prior art, the advantages of this utility model are as follows: When in use, the empty spool is fitted onto the spool positioning seat and attracted to the spool placement platform by multiple magnets, thereby fixing the spool. This solves the problem that the spool installation and disassembly are complicated due to the bolt fixing of the spool in the prior art. The air inlet pipe is connected to the air blowing valve, and compressed gas is blown out from multiple vertical air blowing holes on the anti-tangle air blowing seat. The air blows out from the inside to the outside, and the airflow forms a ring. This solves the problem that the drooping spool end is difficult to find in the prior art. The ring airflow keeps the spool end in a supporting state, preventing the spool end of the empty spool from getting caught in the spool placement seat. This solves the problem that the spool end is easy to get caught in the spool placement seat and cannot be found in the prior art. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0030] like Figures 1 to 11 The diagram shows a wire end finding device for a winding machine, comprising a base 1. Multiple sets of wire end finding devices 2 are arranged on the upper surface of the base 1. Each wire end finding device 2 includes a wire end clamping device 3 and a wire spool fixing structure 4. The wire spool fixing structure 4 includes a rotary motor 5 mounted below the base 1 via a motor frame 10. A transition rotary shaft 6 is arranged on the motor shaft of the rotary motor 5, extending from the lower surface to the upper surface of the base 1. A wire spool placement seat 7 is arranged on the top of the transition rotary shaft 6, and a wire spool 8 is placed on the wire spool placement seat 7. An anti-tangle air blowing seat 9 is also sleeved on the wire spool placement seat 7.

[0031] like Figure 6 As shown, in order to place the coil 8, the coil placement seat 7 further includes a placement seat body 701. The top of the placement seat body 701 is provided with a coil positioning seat 702. The bottom center of the placement seat body 701 is provided with an inner groove 703. The top of the inner side of the inner groove 703 is provided with a connecting shaft insertion hole 704. The top of the coil positioning seat 702 is provided with an upper bolt through hole 705. The upper bolt through hole 705 extends from the top of the placement seat body 701 into the connecting shaft insertion hole 704.

[0032] In order to fix the spool 8, the spool positioning seat 702 is further provided with a horizontal spool placement platform 706 on its side. The upper surface of the spool placement platform 706 is provided with a magnet placement groove 707, and an adsorption magnet 708 is provided in the magnet placement groove 707.

[0033] As shown in Figure 7, in order to make the connection, the transition rotating shaft 6 is further inserted into the connecting shaft insertion hole 704. The top of the transition rotating shaft 6 is provided with a connecting threaded hole 601, and the connecting threaded hole 601 and the upper bolt through hole 705 are coaxially arranged.

[0034] As shown in Figure 8 and Figure 9 As shown, in order to enable air blowing, an anti-tangling air blowing seat 9 is further provided. The anti-tangling air blowing seat 9 includes a cylindrical body 901 with a circular structure. The cylindrical body 901 is provided with a plurality of vertical air blowing holes 902. The vertical air blowing holes 902 extend from the bottom of the cylindrical body 901 to the upper surface. The base 1 is provided with a plurality of gas transition holes 903. The gas transition holes 903 are coaxially arranged with the vertical air blowing holes 902. An air inlet pipe 904 is provided at the bottom of the gas transition holes 903.

[0035] As shown in Figure 10, in order to achieve the function of connection and fixation, the motor frame 10 further includes multiple motor connection transition plates 1001. The motor connection transition plates 1001 are connected to the rotary motor 5. Multiple connection support columns 1002 are provided on the motor connection transition plates 1001. One end of the connection support column 1002 is fixed to the motor connection transition plate 1001, and the other end is connected to the base 1.

[0036] As shown in Figure 11, in order to achieve the clamping function, the wire end clamping device 3 further includes a clamping moving cylinder 301, a double-axis clamping cylinder 302 is provided on the cylinder shaft of the clamping moving cylinder 301, and a gripper 303 is provided on the cylinder shaft of the double-axis clamping cylinder 302.

[0037] In use, the empty coil 8 is fitted onto the coil positioning seat 702. In this patent, the top of the coil positioning seat 702 is provided with an inclined structure, which facilitates the placement of the coil 8. The coil 8 will fall onto the coil placement platform 706. The coil placement platform 706 is provided with a magnet placement groove 707, in which multiple magnets are fixed. When the coil 8 falls onto the coil placement platform 706, it will be attracted by the magnets, thereby fixing the coil 8 and the coil positioning seat 702. The above-mentioned method of using magnets to attract solves the problem of the cumbersome installation and disassembly caused by the coil 8 being fixed by multiple bolts in the prior art, and improves the efficiency and flexibility of the device.

[0038] In the prior art, multiple air columns are used to blow air onto the spool 8, and the air columns are located on the outside of the spool 8. In this way, during the blowing process, the air columns can easily blow the pre-wound connecting wire onto the spool positioning seat 702, causing the pre-wound connecting wire to be wound onto the spool placement seat 7.

[0039] In this patent, after the coil 8 is fixed, a connecting wire is pre-wound onto the coil 8. This pre-wound connecting wire floats in the air. One end of the air inlet pipe 904 is connected to the blower, and the other end is connected to the gas transition hole 903. The anti-tangle blower seat 9 is then fitted onto the coil placement seat 7. The anti-tangle blower seat 9 is then mounted on the base 1. The vertical air hole 902 on the anti-tangle blower seat 9 is aligned with the gas transition hole 903. The anti-tangle blower seat 9 is then fixed to the base 1 by welding or adhesive. The vertical air inlet 902 is located on the inner side below the spool 8. When the air valve is activated, it blows air along the air inlet pipe 904. Compressed gas enters from the air inlet pipe 904 and is blown out from the vertical air inlet 902. The blown gas impacts the spool 8 and is blown out from the bottom of the spool 8 from the inside to the outside. During the blowing process, the pre-wound connecting wire on the spool 8 is blown away towards the edge of the spool 8, effectively preventing the pre-wound connecting wire from being wound into the spool positioning seat 702, so as to facilitate the subsequent gripping of the pre-wound connecting wire.

[0040] When the pre-wound connecting wire on the spool 8 floats in the air, the rotary motor 5 is started. The rotary motor 5 drives the spool placement seat 7 and the spool 8 to rotate. At the same time, the clamping moving cylinder 301 and the dual-axis clamping cylinder 302 of the wire end clamping device 3 are started. The cylinder shaft of the dual-axis clamping cylinder 302 is equipped with a gripper 303, and a photoelectric detection sensor is set on the gripper. Through the cooperation of the above cylinders, the pre-wound connecting wire on the spool 8 is gripped. The gripping method and principle are the same as the method in the patent document cited in the background technology of this patent.

[0041] The above method solves the problem that the installation and disassembly of the spool are complicated due to the use of bolts to fix the spool in the prior art. By connecting the air inlet pipe to the air blowing valve, compressed air is blown out from multiple vertical air blowing holes on the anti-winding air blowing seat 9, blowing air from the inside out, which can effectively prevent the wire end of the spool to be wound from getting into the spool placement seat, thus solving the problem that the wire end is easy to get into the spool placement seat in the prior art.

[0042] In summary, in this patent, an empty spool 8 is fitted onto the spool positioning seat 702 and fixed to the spool positioning seat 702 by multiple magnets, thereby achieving the fixation of the spool 8. In this patent, there are multiple outer air nozzles on the outside of the spool. The structure and installation position of the outer air nozzles are the same as those of the air column structure in the prior art. The multiple air nozzles blow the wire end towards the clamp 303, and then blow air through the multiple air holes of the anti-tangle air blower seat 9. The blown air forms a ring, and the ring air lifts the wire end. This device solves the problem of drooping wire ends in existing technologies, making it difficult to find the wire ends. Combined with the airflow from the outer nozzle, it can quickly and effectively blow the wire ends into the clamping claw 303 area. After the photoelectric switch on the side of the clamping claw 303 detects the wire end, the signal is fed back to the control system, which controls the clamping claw 303 to clamp the wire end, thus quickly finding the wire end and enabling the equipment to proceed with the subsequent work process. This device prevents the wire ends of empty wire reels from getting tangled in the wire reel holder, solving the problem in existing technologies where wire ends easily get tangled in the wire reel holder and cannot be found.

[0043] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
