Description

Technical Field

[0001] This invention relates to an apparatus and method for automatically removing protective paper from transposition lines, belonging to the technical field of special equipment for transformer manufacturing. Background Technology

[0002] With the continuous optimization of transformer product structure, the use of transposed wire windings in transformer products is becoming increasingly common, with some products even using transposed wire windings. The outer layer of the transposed wire conductor is protected by paper, as seen in Chinese patents CN201110398780.6 ("Miniature Transposed Wire with Partial Insulation Protection Layer") and CN201610499879.8 ("Packaging for a Single Transposed Wire"). During transformer coil winding, the protective paper of the transposed wire needs to be removed while the coil is being wound. The protective paper contains a nylon rope as a tension cable; pulling this cable removes the protective paper. However, existing technologies do not utilize equipment for removing the protective paper when winding transformer coils with transposed wires; removal requires manual operation by pulling the nylon rope, consuming significant manpower and resources, which impacts coil winding efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an apparatus and method for automatically removing protective paper from transposition wires. This method automatically pulls the cable holding the protective paper of the transposition wires to automatically remove the outer layer of protective paper, saving manpower and resources, improving the winding efficiency of transformer coils, reducing production costs, and solving the aforementioned technical problems existing in the prior art.

[0004] The technical solution of this invention is:

[0005] An automatic device for removing protective paper from transposition lines includes a cable organizer, a cable controller, and a cable winding system. The cable organizer comprises a mounting rod, fastening bolts, longitudinal beams, limiting plates, a transverse limiting rod, a longitudinal limiting rod, and a mounting base plate. The mounting rod is a horizontally arranged transverse beam. The tops of two longitudinal beams are connected to the mounting rod via fastening bolts. The longitudinal beams are vertically arranged, and their bottoms are fixed to the mounting base plate. The mounting rod, mounting base plate, and two longitudinal beams together form a rectangular frame. Two limiting plates are respectively fixed to the inner sides of the two longitudinal beams, and the limiting plates are equipped with… There are multiple grooves, and the number and position of the grooves on the two limiting plates are the same, corresponding to each other. There are multiple transverse limiting rods, with their two ends placed in the corresponding grooves of the two limiting plates respectively. Two vertically arranged longitudinal limiting rods are set inside the rectangular frame, and the two ends of the longitudinal limiting rods are fixed to the mounting rod and the mounting base plate respectively. Multiple transverse limiting rods and two longitudinal limiting rods are arranged intersectingly inside the rectangular frame, forming multiple rectangular through holes between the two longitudinal limiting rods. The transposition line passes through the rectangular through holes.

[0006] The cable controller and winding system are mounted on a mounting plate below the mounting rod. The cable controller consists of a cable front limit switch, a control linkage, a micro switch, and a cable rear limit switch mounted on the mounting plate. The cable front limit switch and cable rear limit switch are respectively located at the front and rear ends of the control linkage, and the control linkage is matched with the micro switch. There are multiple sets of cable controllers, matching the number of transposition lines. The cable winding system includes a motor, a bearing housing, and a winding shaft mounted on the mounting plate. The motor output shaft is the winding shaft, which is installed in the bearing housing. The number of cable winding systems matches the number of cable controllers. After passing through the cable front limit switch and the cable rear limit switch, the transposition line cable is wound onto the winding shaft. The transposition line cable between the cable front limit switch and the cable rear limit switch presses the control linkage to touch the micro switch, thereby controlling the motor to start and stop. The traction cable tears the protective paper of the transposition line, and the protective paper detaches from the transposition line. The transposition line after the protective paper is detached enters the winding machine to wind the transformer coil.

[0007] Furthermore, the mounting plate is also equipped with an electrical control system. The main body of the electrical control box of the electrical control system is mounted on the mounting plate. The main body of the electrical control box is equipped with a sub-control selection switch, a main switch button, and an emergency stop button. The sub-control selection switch is used to select the motor to be operated. The number of sub-control selection switches corresponds to the number of transposition wires required for coil winding. The main switch button is the main control switch for the power supply. The emergency stop button is an emergency button for sudden situations.

[0008] Furthermore, bearings are provided at both ends of the transverse limiting rod, allowing the transverse limiting rod to rotate freely within the bearings, facilitating the passage of the transposition line through the rectangular through hole without damaging the transposition line.

[0009] Furthermore, the winding shaft is provided with a cutter relief groove; the cutter relief groove on the winding shaft facilitates the removal of the wound cable.

[0010] Furthermore, the mounting rod is used to install the cable organizer onto the cable reel frame, which holds the spool of transposition cable (the transposition cables are all wound on the axle); the groove on the limiting plate is used to limit the position of the lateral limiting rod and facilitate the removal of the lateral limiting rod; the lateral limiting rod separates the transposition cables longitudinally so that they do not interfere with each other; the longitudinal limiting rod is used to limit the left and right positions of the transposition cables so that the transposition cables separate laterally so that they do not interfere with each other.

[0011] Furthermore, the micro switch is a limit switch of a 24V safety voltage switch, which controls the on / off of the motor power supply during use; the control linkage is the trigger of the micro switch; the front limit and rear limit of the cable can facilitate the insertion and extraction of the transposition line, while the tension cable presses against the control linkage.

[0012] Furthermore, the front and rear limiters of the cable are open annular structures, and the cable is inserted from the opening.

[0013] Furthermore, the cable front limit is mounted on the mounting bracket, and the mounting bracket is mounted on the mounting plate.

[0014] A method for automatically removing transposition line protective paper, using the above-mentioned device, includes the following steps:

[0015] The transposition wire is led out from the transposition wire spool on the wire reel frame and passes through the rectangular through hole on the wire organizer; a portion of the cable inside the protective paper of the transposition wire is torn out and fixed to the winding shaft of the cable winding system after passing through the front and rear limit switches of the cable controller; after the cable is torn and the protective paper falls off, the transposition wire enters the mold of the winding machine; the corresponding motors of the winding machine and the cable winding system are started, the winding machine pulls the transposition wire and drives the transposition wire spool to rotate and release the wire, the motor drives the winding shaft to rotate and wind the cable onto the winding shaft, after the cable tears and the protective paper of the transposition wire breaks and falls off, the transposition wire is wound into a transformer coil on the mold of the winding machine.

[0016] The cable is controlled by a front and rear limit switch. When the control switch touches a microswitch, the motor power is switched on, and the protective paper for the transposition wire is automatically removed. When the winding machine stops rotating and other operations are needed for coil winding, the transposition wire spool also stops rotating. The transposition wire remains stationary, and the motor continues to rotate and wind the cable. When the cable reaches a certain angle, it triggers the control switch, automatically cutting off the motor power. The motor stops rotating and ceases winding the cable, thus stopping the automatic removal of the transposition wire protective paper. When the winding machine resumes rotating and the coil is wound normally, the transposition wire continues to move forward, and the cable moves forward synchronously. The pressure on the control switch decreases, the motor is switched on, and the winding spool rotates to continue winding the cable, causing the protective paper for the transposition wire to fall off. This process repeats continuously depending on the coil winding situation until the coil winding is complete. At this point, the wound cable is removed through the retraction groove on the winding spool, and a new transposition wire spool is used to continue winding.

[0017] Furthermore, the number of spools for transposition on the spool frame is multiple, and the transposition lines on the spools pass through multiple rectangular through holes on the cable organizer. The cable of each transposition line is wound around its respective winding shaft.

[0018] Furthermore, the power of the motor is matched with the breaking force of the cable, and the control linkage is activated by the different angle positions of the cable to effectively control the start and stop of the motor, while the cable will not be broken.

[0019] Furthermore, a rectangular through hole can contain one transposition line or multiple transposition lines.

[0020] The positive effects of this invention are: automatically pulling the cable of the transposition wire protective paper to automatically remove the outer protective paper of the transposition wire, saving manpower and material resources and improving the winding efficiency of transformer coils; in the process of using transposition wires to wind coils, this invention can effectively save one person to assist in wire management and reduce the cost of coil manufacturing.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] See attached document Figure 1An automatic device for removing protective paper from transposition lines includes a cable organizer, a cable controller, and a cable winding system. The cable organizer consists of a mounting rod 1, fastening bolts 2, longitudinal beams 3, limiting plates 4, transverse limiting rods 5, longitudinal limiting rods 6, and a mounting base plate 7. The mounting rod 1 is a horizontally arranged beam. The tops of two longitudinal beams 3 are connected to the mounting rod 1 by fastening bolts 2, respectively. The longitudinal beams 3 are arranged vertically, and their bottoms are fixed to the mounting base plate 7. The mounting rod 1, mounting base plate 7, and two longitudinal beams 3 together form a rectangular frame. The two limiting plates 4 are respectively fixed to the inner sides of the two longitudinal beams 3. The upper part is provided with multiple grooves 21. The number and position of the grooves on the two limiting plates 4 are the same and correspond to each other. There are multiple transverse limiting rods 5, and their two ends are placed in the corresponding grooves of the two limiting plates respectively. Two vertically arranged longitudinal limiting rods 6 are set inside the rectangular frame. The two ends of the longitudinal limiting rods 6 are fixed to the mounting rod 1 and the mounting base plate 7 respectively. Multiple transverse limiting rods 5 and two longitudinal limiting rods 6 are arranged intersectingly in the rectangular frame, forming multiple rectangular through holes 22 between the two longitudinal limiting rods 6. The transposition line passes through the rectangular through holes 22.

[0032] See attached document Figure 2-5 The cable controller and winding system are mounted on the mounting plate 13 below the mounting rod 1. The cable controller consists of a cable front limit 8, a control link 9, a micro switch 10, and a cable rear limit 11 mounted on the mounting plate 13. The cable front limit 8 and the cable rear limit 11 are respectively located at the front and rear ends of the control link 9, and the control link 9 is matched with the micro switch 10. Multiple cable controllers are used, matching the number of transposition lines. The cable winding system includes a motor 12, a bearing seat 14, and a winding shaft 15 mounted on the mounting plate 13. The motor 12 outputs... The output shaft is the winding shaft 15, which is installed in the bearing seat 14. The number of cable winding systems matches the number of cable controllers. After passing the front limit 8 and the rear limit 11, the cable of the transposition line is wound on the winding shaft 15. The cable of the transposition line between the front limit 8 and the rear limit 11 presses the control linkage 9 to touch the micro switch 10, thereby controlling the motor 12 to start and stop. The traction cable tears the protective paper of the transposition line, and the protective paper is removed from the transposition line. After the protective paper is removed, the transposition line enters the winding machine 29 to wind the transformer coil 30.

[0033] See attached document Figure 2 and 6The mounting plate 13 is also equipped with an electrical control system. The main body 16 of the electrical control system is mounted on the mounting plate 13. The main body 16 of the electrical control system is equipped with a sub-control selection switch 17, a main switch button 18 and an emergency stop button 19. The sub-control selection switch 17 is used to select the motor to be operated. The number of sub-control selection switches 17 corresponds to the number of transposition wires required for coil winding. The main switch button 18 is the main control switch for the power supply. The emergency stop button 19 is an emergency button for sudden situations.

[0034] See attached document Figure 1 The transverse limiting rod 5 is provided with bearings 23 at both ends. The transverse limiting rod 5 can rotate freely in the bearings, which makes it easy for the transposition line to pass through the rectangular through hole 22 without damaging the transposition line.

[0035] See attached document Figure 2 The winding shaft 15 is provided with a cutter removal groove 24; the cutter removal groove 24 on the winding shaft facilitates the removal of the wound cable.

[0036] The mounting rod 1 is used to install the cable organizer onto the cable reel frame 25, which holds the reel 26 for the transposition cable (the transposition cables are all wound on the reel axle); the groove on the limiting plate 4 is used to limit the position of the lateral limiting rod 5 and facilitate the disassembly of the lateral limiting rod 5; the lateral limiting rod 5 separates the transposition cables longitudinally so that they do not interfere with each other; the longitudinal limiting rod 6 is used to limit the left and right positions of the transposition cables so that they separate laterally so that they do not interfere with each other.

[0037] The micro switch 10 is a limit switch of a 24V safety voltage switch, which controls the on / off of the motor power supply during use; the control linkage 9 is the trigger of the micro switch; the front limit 8 and the rear limit 11 of the cable can easily guide the pull line of the transposition line in and out, while tensioning the cable to compress the control linkage 9.

[0038] See attached document Figure 4 The front limiter 8 and the rear limiter 11 of the cable are open ring structures, and the cable is inserted from the opening.

[0039] See attached document Figure 2 The cable front limiter 8 is mounted on the mounting bracket 31, and the mounting bracket 31 is mounted on the mounting plate 13.

[0040] A method for automatically removing transposition line protective paper, using the above-mentioned device, includes the following steps:

[0041] The transposition wire is led out from the transposition wire spool 26 on the wire reel frame 25 and passes through the rectangular through hole 22 on the wire organizer; a portion of the pull cable 27 inside the protective paper of the transposition wire is torn out and fixed to the winding shaft 15 of the pull cable winding system after passing through the pull cable front limit 8 and pull cable rear limit 11 of the pull cable controller; after the pull cable 27 is torn off the protective paper 28, the transposition wire 20 enters the mold of the winding machine 29; the motor 12 corresponding to the winding machine and the pull cable winding system is started, the winding machine pulls the transposition wire to drive the transposition wire spool 26 to rotate and release the wire, the motor 12 drives the winding shaft 15 to rotate and wind the pull cable onto the winding shaft 15, after the pull cable tears the protective paper of the transposition wire and falls off, the transposition wire winds the transformer coil 30 on the mold of the winding machine 29.

[0042] The cable is pressed by the front limiter 8 and the rear limiter 11 of the cable, which presses the control link 9. The control link 9 touches the micro switch 10, which connects the power to the motor 12 and automatically removes the protective paper 28 of the transposition wire. When the winding machine 29 stops rotating and other operations are required for coil winding, the net pack transposition wire shaft 26 also stops rotating. The transposition wire does not move, and the motor 12 continues to rotate and wind the cable. When the cable reaches a certain angle, it touches the control link 9, which activates the micro switch 10 and automatically cuts off the power to the motor 12. The motor stops rotating and no longer winds the cable, so the protective paper of the transposition wire is no longer automatically removed. When the winding machine 29 continues to rotate and the coil is wound normally, the transposition wire continues to move forward, and the cable moves forward synchronously. The pressure on the control link 9 decreases, the motor is connected, and the winding shaft rotates to continue winding the cable, causing the protective paper of the transposition wire to fall off. This process is repeated continuously according to the coil winding situation until the coil winding is completed. At this point, the wound cable is removed through the unwinding groove 24 on the winding shaft, and a new net packing transposition shaft 26 is used to continue winding.

[0043] The number of the mesh bag transposition spools 26 on the spool frame is multiple. The transposition lines on the mesh bag transposition spools 26 pass through multiple rectangular through holes 22 on the cable organizer. The cable of each transposition line is wound around its respective winding shaft 15.

[0044] The power of the motor 12 is matched with the breaking force of the cable. By controlling the different angles of the cable, the control linkage 9 is activated, effectively controlling the motor to start and stop, while the cable will not break.

[0045] One transposition line or multiple transposition lines can pass through a rectangular through hole 22.

[0046] The cable organizer is a set of detachable / fixed transposition cable separators used to limit the relative position of the transposition cables, ensuring that the parallel transposition cables pass through smoothly without damage, and at the same time limiting the relative position of the transposition cables, the cable controller, and the cable winding system, so as to facilitate automatic control of the motor rotation and stop.

[0047] The number of cable controllers and cable winding systems used is determined by the number of transposition wires to be wound into the transformer coil. For example, if three transposition wires are wound simultaneously, three sets of cable controllers and cable winding systems are used. Each set controls the start and stop of a motor, thereby controlling the cable winding process and ensuring that the removal progress of the protective paper for the transposition wires matches the progress of the transposition wires required for coil winding. The cable controllers and cable winding systems ensure that the cable has sufficient force to tear the protective paper, while also facilitating the collection and unified removal of the cable. Using transposition wires to wind the coil effectively saves one person for auxiliary wire management, improves coil winding efficiency, and reduces coil manufacturing costs.

[0048] The transverse limiting rod 5 and the longitudinal limiting rod 6 are made of insulating material. The transverse limiting rod 5 has bearings at both ends for smooth rolling. The transposition wires are managed by a wire winding device. The transposition wires (electromagnetic wires) are fixed in position and do not interfere with each other. A portion of the cable (nylon material) inside the protective paper of one transposition wire can be manually torn out, enters through the cable front limiter, passes through the control linkage, and is then fixed to the winding shaft by the cable rear limiter. The corresponding motor's sub-control selection switch in the electrical control system is turned on, and the transposition wires are wound sequentially. The protective paper of each transposition wire is automatically removed according to the coil winding requirements, without the need for further manual intervention, until the coil winding is completed. This effectively achieves the required consistency, thereby improving coil winding efficiency and reducing coil manufacturing costs.
