Description

  The present invention relates to a wound core manufacturing apparatus for manufacturing a wound core by sequentially winding and laminating a plurality of iron core blocks made of a steel sheet laminate formed by laminating a plurality of strip-shaped unit steel plates. .

  In this type of wound core manufacturing apparatus, as shown in Patent Document 1, a plurality of strip-shaped unit steel plates are aligned in the length direction, and the positions of one end and the other end in each length direction are as follows. Are stacked on a fixed table in a state of being shifted by a predetermined offset dimension, and steel plate stacking apparatuses for sequentially forming core blocks in which laminated surfaces inclined in a stepwise manner are formed on one end side and the other end side in the longitudinal direction. A series of core blocks formed by the steel plate stacking device are sequentially wound around the winding frame to form a wound core, and a core block sequentially formed by the steel plate stacking device. And a conveying device that conveys toward the winding and laminating apparatus.

  The steel plate stacking device feeds a plurality of strip-shaped unit steel plates formed by cutting a strip-shaped steel strip unwound from a steel strip coil with a shear onto a fixed table along a feed line. By stacking (stacking) a series of unit steel plates that are sequentially fed while shifting the position in the longitudinal direction, an iron core block having stepped laminated surfaces formed at both ends in the longitudinal direction is formed.

  The winding laminating apparatus includes a winding frame that has an outer peripheral surface formed in a cylindrical surface and is rotatably supported by the frame, and a frame that is disposed at the lower end of the winding frame while sharing the axis with the winding frame. And a disc-shaped face plate supported in a freely rotatable manner, and a plurality of rollers arranged around the face plate and supported by the frame so that a part of the face plate runs along the outer periphery of the reel. An endless wrapping belt and a belt driving device for running the wrapping belt are provided. In the conventional wound core manufacturing apparatus, the winding frame and the face plate are provided so as to be able to rotate independently.

  When forming a wound core with this winding laminating apparatus, the wound core is stopped in a state in which the core block receiving position of the winding frame is aligned with the core block introducing portion of the winding laminating apparatus. In this state, the core block whose width direction is directed in the vertical direction (vertical direction) is transported by the transport device toward the core block introducing portion of the winding laminating apparatus, and the laminated surface on the lower end side of the transported iron block is faceplate Inserted between the winding frame and the winding belt in a state of being attached to the upper surface. After that, the winding belt travels in one direction by the belt driving device, and the core block is wound around the outer periphery of the winding frame while the winding frame and the face plate are driven and rotated by the belt through the core block. After the winding of the core block is completed, the winding belt is decelerated and stopped in a state in which the core block receiving position of the winding frame is aligned with the core block introducing portion of the winding laminating apparatus. By repeating these operations, a series of iron core blocks are wound and laminated on the outer periphery of the winding frame, thereby forming the winding core on the outer periphery of the winding frame.

  Since the laminated surface on one end side in the width direction of the iron core block wound sequentially around the outer periphery of the winding frame is in contact with the face plate, it is arranged on substantially the same plane. In addition, a laminated surface inclined stepwise is usually formed at both ends in the longitudinal direction of each core block, so that a predetermined lapping margin is provided at the abutting portion at each end of each core block wound around the outer periphery of the winding frame. A lap portion that is wrapped (overlapped) is formed.

  The wound iron core wound as described above is formed into a rectangular shape in a subsequent process and annealed, and then inserted into the window portion of the winding with each butt portion separated, and then butt again. The parts are abutted to constitute an iron core of a static induction electrical device such as a transformer. In order to improve the assembly workability when the iron core is incorporated in the winding, the butt portion of a series of core blocks wound and laminated around the outer periphery of the winding frame is arranged in a straight line on the lamination surface. It is preferable. Therefore, when winding and laminating iron core blocks with a winding laminator, the winding position of each core block is obtained by numerical calculation so that the butted portions at both ends of a series of core blocks are aligned in a straight line. The introduction position of each core block is managed so that each rotated core block is accurately arranged at the calculated winding position.

JP 2000-106314 A

  In the winding and laminating apparatus provided in the conventional wound core manufacturing apparatus, a straight line is formed on the laminated surface of the wound core in which the butted portions at both ends of a series of core blocks wound around the outer periphery of the winding frame are wound. Even if the winding position of each core block is managed so as to be lined up along the line, the butt portion of a series of core blocks may not be arranged on a straight line. The abutting portions of a series of iron core blocks are arranged along a meandering line or are arranged in a zigzag manner, and the arrangement of the abutting portions may be disturbed. If the arrangement of the butted parts of a series of core blocks in a wound core is disturbed, the assembly workability when incorporating the core into the winding in the subsequent process will deteriorate and the manufacturing efficiency of stationary induction electrical equipment will be reduced. I will let you.

  An object of the present invention is to provide a winding that can prevent the arrangement of abutting portions of a series of core blocks from being disturbed when a series of core blocks is wound around a winding frame to produce a wound core. The object is to provide an iron core manufacturing apparatus.

  The present invention provides a rotatable winding frame disposed with its axis line directed in the vertical direction, and a rotatable disk-shaped face plate disposed on the lower end side of the winding frame while sharing the axis line with the winding frame. An endless winding belt that is guided by a plurality of rollers arranged around the face plate so that a part of the belt runs along the outer periphery of the winding frame, and a belt driving device that runs the winding belt. A series of core blocks made of a laminate of a plurality of strip-shaped unit steel plates, with the laminated surface on one end side in the width direction between the winding belt and the winding frame in a state where the laminated surface is attached to the upper surface of the face plate It is intended for a wound core manufacturing apparatus that manufactures a wound core by inserting the core block into the outer periphery and winding it around the outer periphery of the winding frame while being driven by a winding belt and rotating together with the winding frame.

  In the present invention, a reel driving device that rotates the reel in the same direction as the rotation direction of the core block when winding the iron core block around the reel using the reel drive motor as a drive source, and a face plate drive motor as the drive source. A face plate driving device that drives the face plate to rotate in the same direction as the rotation direction of the iron core block when the iron block is wound around the reel, and an iron core that is driven by the winding belt and is wound around the reel while rotating with the reel. A control device for controlling the reel driving motor and the face plate driving motor is provided so as to rotate the reel and the face plate at an angular velocity equal to the angular velocity of the block.

  As a result of various studies on the conventional wound core manufacturing apparatus, the present inventor has provided the conventional wound core manufacturing apparatus so that the winding frame and the face plate can be rotated independently of each other. When the block is driven by the winding belt and wound around the winding frame, the winding frame and the face plate are rotated by being indirectly driven by the winding belt through the iron core block. When accelerating and decelerating, due to the inertia of the winding frame and the face plate, misalignment occurs between the wound iron core blocks and between the unit steel plates constituting each iron core block. It became clear that the butting part meandered or was placed in a zigzag manner.

  Therefore, in the present invention, as described above, a reel driving device that rotationally drives the reel using the reel driving motor as a driving source and a face plate driving device that rotationally drives the face plate using the face plate driving motor as a driving source are provided. Thus, the reel driving motor and the face plate driving motor are controlled so that the reel and the face plate are rotated at an angular velocity equal to the angular velocity of the iron core block wound around the reel. With this configuration, both when accelerating the winding belt toward a specified speed and when decelerating and stopping the traveling winding belt, the winding belt and the winding frame are already wound. Since the core block and the face plate are always rotated at the same angular velocity, there is a positional shift between the already wound core blocks and between the unit steel plates constituting each core block due to the inertia of the winding frame and face plate. This can be prevented, and the arrangement of the butt portions of the series of core blocks can be prevented from being disturbed.

  In a preferred aspect of the present invention, the control device includes a reel speed detecting unit that detects the angular velocity of the reel, a face plate speed detecting unit that detects the angular velocity of the face plate, an outer diameter of the reel, and an outer periphery of the reel. An iron core block speed calculating means for calculating an angular velocity of an iron core block driven by the winding belt and rotating together with the winding frame from the sum of the winding thickness of the wound core and the running speed of the winding belt; A reel drive motor controller that controls the reel drive motor so that the angular velocity of the reel detected by the velocity detector matches the angular velocity of the iron block calculated by the iron block speed calculator, and a face plate speed detector And a face plate drive motor control unit that controls the face plate drive motor so that the detected angular velocity of the face plate matches the angular velocity of the iron core block calculated by the iron block speed calculating means.

  In the present invention, a reel driving device that rotationally drives the reel using the reel driving motor as a driving source and a face plate driving device that rotationally drives the face plate using the face plate driving motor as a driving source are provided. Since the reel driving motor and the face plate drive motor are controlled so as to rotate the reel and the face plate at an angular velocity equal to the angular velocity of the iron core block, when accelerating and decelerating the winding belt, Due to the inertia of the winding frame and the face plate, it is possible to prevent positional deviation between the wound iron core blocks and between the unit steel plates constituting each iron core block. Therefore, it is possible to prevent a situation where the butted portions of the series of core blocks are arranged along a meandering line or zigzag on the laminated surface of the wound core. It is possible to prevent the assembling workability from being deteriorated when incorporated in the winding.

From this, the running speed V [m / sec] of the belt 203 is detected. This traveling speed is equal to the peripheral speed of the outer peripheral surface of the iron core block 1 being newly wound around the winding frame 201.

The angular velocity ω i (= V / 2πR) [rad / sec] of the laminated core block is calculated.

  The core block sensor 607 is a sensor that detects that the core block to be wound next is introduced into the core block introduction part of the winding laminating apparatus 2 and that the winding of the core block around the winding frame is completed. This sensor detects, for example, that a new core block has been introduced into the winding laminator 2 when the core block 1 reaches the introduction portion, and the introduced iron block is wound around the reel and then It can be constituted by a position sensor that detects the completion of winding of the newly introduced core block when the end portion passes. Position sensors include limit switches, optical sensors that perform detection operations when the iron block enters between the light emitter and the light receiver, and when the iron block leaves between the light emitter and the light receiver.

  When the wound core is manufactured by the wound core manufacturing apparatus of the present embodiment, the iron core blocks 1 sequentially formed by the steel plate stacking apparatus (not shown) are clamped by the clamp 301 of the raising apparatus 3 and traversed to the final traverse position. After that, the iron core block 1 is raised, and the upper part of the iron core block 1 clamped by the clamp 301 is clamped by the clamp device 403 of the conveying device 4, and the clamp 301 of the raising device 3 is unclamped. To. Next, the iron core block 1 clamped by the clamp device 403 is moved toward the iron core block supply device 5. The tip of the lead portion 1A protruding forward from the clamp device 403 of the core block 1 is inserted between the guide blocks 502 and 503 from the core block receiving port 5A of the core block supply device 5, and the core block is supplied to the core block supply device 5. Insert inside.

  After the core block 1 is inserted into the core block supply device 5, the clamp device 403 is put into an unclamped state, and the clamped core block 1 is lowered onto the bottom plate 501 of the core block supply device 5. Thereby, the position of the end surface of the width direction of the unit steel plate which comprises the iron core block 1 is arrange | equalized. Next, the feeding mechanism provided in the iron core block supply device 5 is operated to feed the iron core block 1 between the winding belt 203 and the winding frame 201 from the iron core block introduction part. Next, the core block 1 introduced by driving the winding belt 203 is wound around the outer periphery of the winding frame 201.

  In the present embodiment, a reel driving device 211 that rotationally drives the reel using the reel driving motor 238 as a driving source, and a face plate driving device 212 that rotationally drives the face plate using the face plate driving motor 223 as a driving source are provided. Since the winding frame drive motor 238 and the face plate drive motor 223 are controlled to rotate the winding frame 201 and the face plate 210 at an angular velocity equal to the angular velocity ω i of the iron core block 1 wound around the frame 201, When accelerating the winding belt 203 toward a specified speed and decelerating and stopping the traveling winding belt, the winding frame 201 and the iron core block and face plate already wound around the winding frame 210 is always rotated at the same angular velocity, and due to the inertia of the winding frame 201 and the face plate 210, it is possible to prevent positional deviation between the already wound steel plates. It is possible to prevent a situation in which the butted portions of the series of core blocks 1, 1,... Are arranged along a meandering line on the laminated surface of the wound cores. Assembling workability at the time of constituting can be improved.
