Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a winding machine capable of concentrically winding a winding around a salient pole part.
[0002]
[Prior art]
In a conventional general winding machine, a nozzle from which a winding conductor is drawn out from a tip end portion is inserted into a slot of a core, and the winding conductor is wound around a salient pole portion of the core. Conventionally, a pre-formed winding is mounted on the salient pole part.
[0003]
[Problems to be solved by the invention]
However, when inserting the nozzle into the slot of the core, it is necessary to secure a space for inserting the nozzle inside the slot, and thus there is a limit to increasing the space factor of the winding. In addition, since the nozzle is inserted inside the slot, there is a limit to increasing the diameter of the winding conductor. In addition, attaching a pre-formed winding to the salient pole portion causes a problem that it takes much time to form the winding when the wire diameter of the winding conductor becomes large.
[0004]
An object of the present invention is to provide a winding machine capable of intensively winding a winding around a salient pole portion without inserting a nozzle into a slot of a core.
[0005]
In addition to the above object, another object of the present invention is to provide a winding machine capable of aligning winding conductors.
[0006]
[Means for Solving the Problems]
The present invention is configured by laminating a plurality of steel plates, and is formed such that a plurality of slots and a plurality of salient pole portions are alternately arranged in the circumferential direction on the inner peripheral side of the annular yoke. An inner opening that opens toward the center line that passes through the center of each annular yoke, a front opening that opens on the front end face located on one side in the stacking direction in which a plurality of steel plates are stacked, and the other in the stacking direction Winding the winding conductor led out from the tip of the nozzle intensively around each of the plurality of salient pole portions of the core for electrical equipment having a rear opening that opens to the rear end face located on the side Intended for winding machines that form wire sections. In general, the inner wall surface of the slot is covered with a slot insulator formed of an insulating material such as an insulating resin.
[0007]
In the present invention, the nozzle moving mechanism for moving the nozzle has a first moving region located in front of the front end surface of the core, a second moving region located in the rear of the rear end surface of the core, and a first moving region. In a third movement area between the first movement area and the second movement area, a predetermined movement operation described below is performed.
[0008]
First, in the first moving region located forward of the front end surface of the core, the nozzle moving mechanism is arranged along a virtual straight line passing through the front end surface and the center line (in a certain virtual line extending radially around the center line). A first movement operation that moves the nozzle in a direction away from the center line, while maintaining a parallel relationship with or along the imaginary line), and the nozzle in one of the circumferential directions around the center line passing through the center of the yoke. A second movement operation for rotating a predetermined angle in the direction and a third movement operation for moving the nozzle in a direction toward the center line along a virtual straight line passing through the front end face and the center line are performed. .
[0009]
The nozzle moving mechanism is configured to move the nozzle in a direction away from the center line along a virtual straight line passing through the rear end surface and the center line in the second movement region located outside the rear end surface of the core. And a second moving operation for rotating the nozzle by a predetermined angle in the other circumferential direction around the center line passing through the center of the yoke, and centering the nozzle along a virtual straight line passing through the rear end surface and the center line. A third movement operation for moving in the direction toward the line is performed.
[0010]
In the first movement region and the second movement region, the amount of movement of the nozzles when performing the first movement operation and the third movement operation may be increased or decreased in stages, but the conductor alignment as will be described later When using a mechanism, etc., the amount of movement of the nozzle can be made constant or reduced.
[0011]
Further, the nozzle moving mechanism is configured to move one nozzle when moving the nozzle from the first movement area to the second movement area in the third movement area between the first movement area and the second movement area. Without inserting the tip of the nozzle along the inner opening of one slot located in one circumferential direction of the two slots located on both sides in the circumferential direction of the salient pole portion When the nozzle is moved from the second movement region to the first movement region by performing the first movement operation to move, the other of the two slots positioned on both sides in the circumferential direction of one salient pole portion A second movement operation is performed to move along the inner opening of the slot and without inserting the tip of the nozzle into the other slot.
[0012]
The nozzle moving mechanism repeatedly moves the nozzles in the respective moving areas in the order of returning to the first moving area, the third moving area, the second moving area, the third moving area, and the first moving area. Thus, the winding part is formed in the salient pole part without inserting the tip part of the nozzle into the slot. This order does not necessarily mean that the winding operation must be started from the first movement region, but merely indicates the movement path of the nozzle.
[0013]
When the nozzle moving mechanism causes the nozzle to perform the above-described operation, in the third moving region, the nozzle moves along the inner opening of the slot, so that all the winding conductors drawn from the tip of the nozzle are moved. Or most of it enters the inside of the slot through the inner opening of the slot. Then, when the nozzle moves in the first and second moving regions, the position of the winding conductor (or the distance from the center line) on the end face of the salient pole portion located on the front end face and the rear end face of the core is determined. Is done.
[0014]
In order to make it easier for the winding conductor drawn from the nozzle to enter the inside of the slot when the nozzle is moved in the third movement region, when the nozzle moves along the inner opening of the slot, It is preferable to provide a pair of guide members for guiding the winding conductor drawn from the tip portion into the slot. The pair of guide members are arranged at intervals on both sides in the circumferential direction of the inner opening so as to form a conductor guide slit facing the inner opening of the slit. By providing such a pair of guide members, the winding conductor can be smoothly inserted into the slot even if there is a slight shift in the positional relationship between the position of the nozzle and the inner opening of the slot.
[0015]
In particular, the guide member has a structure having a contact portion that contacts the magnetic pole surface of the salient pole portion, and an upright portion that extends from the contact portion toward the center line. And a pair of guide member is arrange | positioned so that a conductor guide slit may be formed between each contact part. If it does in this way, positioning with respect to a core of a pair of guide member becomes easy because a contact part contacts a magnetic pole surface. Further, since the upright portions are located on both sides of the winding conductor, the upright portions guide the winding conductor into the slit while protecting the winding conductor during the winding operation.
[0016]
When the pair of guide members is fixed to a member constituting the nozzle moving mechanism so as to rotate together with the nozzle when the nozzle rotates in the first movement region and the second movement region. A mechanism for separately rotating the pair of guide members becomes unnecessary, and the pair of guide members can be rotated by an appropriate amount simultaneously with the rotation of the nozzle.
[0017]
More specifically, the winding machine of the present invention includes a core support base that supports the core such that the center line of the core extends in the horizontal direction. The core support may have a structure that supports the core in a fixed state, or may support the core so that the core can be rotated at a predetermined angle with respect to the nozzle. If the core support is rotated, the amount of nozzle rotation can be reduced. The nozzle moving mechanism more specifically includes a vertical movement mechanism that vertically moves the nozzles on both sides of the front end surface and the rear end surface of the core supported by the core support, and a front end surface and a rear end surface of the core. A rotation mechanism that rotates the nozzle around the center line on both sides and a horizontal movement mechanism that moves the nozzle horizontally along the center line are provided. The horizontal movement mechanism is, for example, two guide rails that are supported by a frame, extend in the horizontal direction, and are arranged in parallel at a predetermined interval, and are slidable in the horizontal direction with respect to the two guide rails. A slider that is fixed and extends in the space between the two guide rails and supports the nozzle so as to be slidable in the longitudinal direction of the nozzle, and engages with a part of the nozzle while the slider is sliding. It is possible to provide a structure including a stopper member that prevents sliding in the longitudinal direction, and a slide driving force generator that generates a driving force that is fixed to the frame and that slides the slider along the two guide rails. . The pair of guide members described above can be fixed to this frame. The vertical movement mechanism includes first and second nozzle engaging members that engage with a part of the nozzle when the nozzle is positioned in the first moving region and the second moving region, and the first and second moving members. It can be set as the structure provided with the 1st and 2nd vertical-motion drive force generator which generate | occur | produces the drive force which moves the nozzle engaging member of this up and down direction. Further, the rotation mechanism can be configured to rotate the frame at a predetermined angle around the center line. In this case, the nozzle engaging member of the vertical movement mechanism has a structure that engages with a part of the nozzle so as to allow the nozzle to rotate when the rotating mechanism rotates the frame. is doing.
[0018]
With the above structure alone, the windings can be concentratedly wound, but cannot be aligned. Therefore, in order to make this possible, the nozzle is pulled out from the nozzle during the second movement operation or after the second movement operation is finished in the first movement region and the second movement region. A pair of conductor alignment mechanisms are provided on both sides of the core support base. The pair of conductor alignment mechanisms includes a needle that engages with the winding conductor and pulls the needle away from the center line to position the winding conductor at a predetermined alignment position. The operation of the needles of the pair of conductor alignment mechanisms needs to be related to the amount of nozzle lowering by the vertical movement mechanism. Because there is a winding conductor at a position below the position where the nozzle is lowered, in order to pull down this winding conductor to a predetermined position, the lowering position of the tip of the nozzle and the reaching position of the needle are always This is because it is necessary to maintain a certain relationship. After the needle hooks the winding conductor, the needle pulls the winding conductor down along the front end face and the rear end face of the salient pole portion of the core. Therefore, the shape of the needle is preferably a shape suitable for hooking and pulling down the winding conductor.

[0022]
As shown in FIG. 4B, the horizontal movement mechanism 17 is a pair of elongated plate-like members 25 and 27 that are arranged in parallel and extend in the horizontal direction, and a pair that connects the pair of plate-like members 25 and 27.

Conceptually, a pin-like member 24 a provided at the upper end of the nozzle 23 and extending in the horizontal direction and the direction orthogonal to the longitudinal direction of the nozzle 23 engages or contacts the upper end surface of the stopper member 41, thereby 23 is prevented from moving in the vertical direction. As will be described later, a pair of pin-like members 24b and 24c extending on both sides in the horizontal direction are also provided at the upper end of the nozzle 23.
[0023]
A main body 43a of an air cylinder 43 as a slide driving force generating device that generates a driving force for sliding the slider 39 along the two guide rails 35 is fixed to the plate-like member 25 of the frame 33. Specifically, the body of the air cylinder 43 43a An extension portion that is extended to the outside of the frame 33 by a part of the slider 39 is fixed to the tip end portion of the shaft 43b extending from the front side. When the shaft 43b of the air cylinder 43 moves to the main body 43a side, that is, the right side (that is, the rear side) in the state shown in FIG. 1, the slider 39 also slides rearward while being guided by the guide rail 35. Further, when the shaft 43b of the air cylinder 43 moves to the main body 43a side, that is, the left side (that is, the front side) in the state of FIG. 1, the slider 39 also slides forward while being guided by the guide rail 35.
[0024]
A pair of guide members 45 and 47 are fixed to lower end portions of the pair of plate-like members 25 and 27 of the frame 33. The pair of guide members 45 and 47 includes Slot 7 The inner opening 7a is disposed at intervals on both sides in the circumferential direction so as to form a conductor guide slit 49 that faces the inner opening 7a. Providing such a pair of guide members 45 and 47 allows the winding conductor to be smoothly inserted into the slot 7 even if the positional relationship between the nozzle 23 and the inner opening 7a of the slot 7 is slightly shifted. it can. The guide members 45 and 47 in this example have contact portions 45a and 47a that come into contact with the magnetic pole surface of the salient pole portion 9, and standing portions 45b and 47b that extend from the contact portion toward the center line CL. The pair of guide members 45 and 47 are arranged such that a conductor guide slit 49 is formed between the contact portions 45a and 47a. If it does in this way, positioning with respect to the core 3 of a pair of guide members 45 and 47 becomes easy because the contact parts 45a and 47a contact a magnetic pole surface. Further, since the standing portions 45b and 47b are located on both sides of the winding conductor, the winding portions are guided into the slot 7 while the standing portions 45b and 47b protect the winding conductor during the winding operation. To do.
[0025]
The horizontal movement mechanism 17 is supported by a so-called cantilever on a mechanism support 21 via a rotation mechanism 19. In a state where the horizontal movement mechanism 17 is inserted inside the core 3, the contact portions 45 a and 47 a of the pair of guide members 45 and 47 described above come into contact with the magnetic pole surface of the salient pole portion 9, whereby the horizontal movement mechanism 17 is It will be supported in two places. The rotation mechanism 19 is configured by a combination of a servo motor and a gear mechanism, and rotates or swings within a predetermined angle range. The rotation center of the rotation mechanism 19 coincides with the center line CL of the core 3 described above. Therefore, when the rotation mechanism 19 rotates within a predetermined angular range, the horizontal movement mechanism 17 described above is centered on the center line CL. In Then, it rotates or swings within a predetermined angle range. As a result, the nozzle 23 is also centered on the center line CL. In Can be rotated or swung.
[0026]
A vertical movement mechanism 51 for moving the nozzle 23 up and down is mounted on a horizontal frame 55 fixed to a support column 53 fixed to the base 13. The vertical movement mechanism 51 includes first and second vertical movement driving force generators 57 and 59 each including an electromagnetic actuator supported by the horizontal frame 55, and the first and second vertical movement driving force generators 57 and 59. 59, each of which moves up and down to engage with the pin-shaped member 24b or 24c fixed to the nozzle 23 when the nozzle 23 is positioned in a first movement region and a second movement region described later. The first and second nozzle engaging members 61 and 63 for moving the nozzle up and down. The nozzle engaging members 61 and 63 are respectively formed with long holes 62 and 64 that open on the side surfaces facing each other or facing the core 3. These long holes 62 and 64 have a shape in which the above-described pin-like member 24b or 24c provided at the upper end of the nozzle 23 is fitted or engaged. In order to allow the nozzle 23 to rotate or swing within a predetermined angle range about the center line CL in a state where the pin-like member 24b or 24c is fitted in the long holes 62 and 64, a theory is provided. Specifically, the long holes 62 and 64 must have an arc shape. However, when the rotation angle range or the swing angle range is small, the width of the long holes 62 and 64 is appropriately larger than the diameter of the pin-shaped member 24b or 24c even if the long holes 62 and 64 are linearly formed. By doing so, the nozzle 23 can be allowed to rotate or swing. In this example, the long holes 62 and 64 have a linear shape extending in a direction orthogonal to the horizontal direction and the vertical direction.
[0027]
The horizontal movement mechanism 17, the rotation mechanism 19, and the vertical movement mechanism 51 constitute a nozzle movement mechanism 15. The nozzle moving mechanism 15 includes a first moving region located on the outer side (front side) than the front end surface of the core 3, a second moving region located on the outer side (rear side) than the rear end surface of the core, and a first moving region. The nozzle 23 is moved in a third movement area between the first movement area and the second movement area. Here, the state in which the pin-like member 24b located on the front side of the upper end of the nozzle 23 is engaged with the first nozzle engaging member 61 and the nozzle 23 can move in the vertical direction is the first movement of the nozzle 23. In this state, the pin 23 is located in the region and the pin-like member 24c located on the rear side of the upper end of the nozzle 23 is engaged with the nozzle engaging member 63 so that the nozzle 23 can move in the vertical direction. This is a state located in the second movement region. A state where the nozzle 23 can move only in the horizontal direction is a state where the nozzle 23 is located in the third movement region.
[0028]
The base 13 is provided with a pair of conductor alignment mechanisms 65 and 67 on both sides in the front-rear direction of the core support 11. The pair of conductor alignment mechanisms 65 and 67 includes needles 69 and 71 and needle moving mechanisms 73 and 75, respectively. The needles 69 and 71 have a shape capable of pulling down the winding conductor and pressing the winding conductor against the end face of the corresponding salient pole portion 9. That is, the needles 69 and 71 are wound around the nozzle 23 while the nozzle 23 is rotating in the first movement region and the second movement region or after the second rotation operation is finished. It has a shape that engages with the wire conductor. Specifically, the needles 69 and 71 are curved so that the lower surfaces of the tip portions of the needles 69 and 71 are concave downward, or the engaged winding conductors can be smoothly guided to the tip portions. The needle moving mechanisms 73 and 75 are provided when the nozzle 23 is in the first and second moving regions and the winding conductor is routed along the front end face and the rear end face of the salient pole portion 9. The needles 69 and 71 are brought close to the front end face and the rear end face of the corresponding salient pole part 9, and then the needles 69 and 71 are pulled down in the direction away from the center line CL (lower side). The conductor is positioned at a predetermined alignment position. In order to make this possible, the operation of the needles 69 and 71 of the pair of conductor alignment mechanisms 65 and 67 needs to be related to the downward movement amount of the nozzle 23 by the vertical movement mechanism 51. This is because there is a winding conductor at a position below the position where the nozzle 23 is lowered, and in order to pull down this winding conductor to a position necessary for alignment of the winding conductor, the lowered position of the tip of the nozzle 23 This is because it is necessary to always maintain a certain relation between the reaching positions of the needles 69 and 71. Such a relationship can be easily realized by sequence control.
[0029]
The nozzle moving mechanism 15 of the winding machine 1 configured as described above performs the following movement operation in the first movement region located in front of the front end face of the core 3. First, in a state where the pin-shaped member 24b is engaged with the elongated hole 62 of the nozzle engaging member 61, the vertical driving force generator 57 moves the nozzle engaging member 61 downward, and the nozzle 23 is moved to the front end surface and the center. The nozzle 23 is moved in a direction away from the center line CL along a virtual straight line passing through the line CL (first movement operation in the first movement region). Since the nozzle 23 slidably penetrates the through hole of the slider 39 of the horizontal movement mechanism 17, the slider 39 does not hinder the movement of the nozzle 23 at this time. Next, the rotation mechanism 19 has a predetermined angle θ (an angle between the centers of two adjacent slots) in one circumferential direction of the yoke of the core 3 with the frame 33 of the horizontal movement mechanism 17 as the center line CL. ) (The second movement operation in the first movement region). As a result, the nozzle 23 rotates by a predetermined angle θ in one circumferential direction around the center line CL. Together with this rotation operation or after the rotation operation is completed, the needle 69 of the conductor alignment mechanism 65 is engaged with the winding conductor W drawn from the nozzle 23. The conductor alignment mechanism 65 operates the needle 69 so that the winding conductor is located at the alignment position. Thereafter, the vertical drive force generator 57 of the vertical movement mechanism 51 of the nozzle movement mechanism 15 moves the nozzle engagement member 61 upward, and moves the nozzle 23 along a virtual straight line passing through the front end surface and the center line CL. The nozzle 23 is moved in the direction (upward) toward the center line CL (third movement operation in the first movement region). The outline of the movement of the nozzle 23 in the first movement region is as shown in a part of FIGS.
[0030]
Next, in order to move the nozzle 23 from the first movement region to the second movement region, the nozzle movement mechanism 15 is one of the two slots 7 and 7 located on both sides in the circumferential direction of one salient pole portion 9. The nozzle 7 is moved along the inner opening 7a of the one slot 7 located in one of the circumferential directions without inserting the tip of the nozzle 23 into the one slot (the first movement in the third movement region). Action ). Specifically, the air cylinder 43 as a slide driving force generator of the horizontal movement mechanism 17 moves the slider 39 from the front position to the rear position (from the left end to the right end in FIG. 1). When the pin-like member 24 b comes out of the long hole 62 as the slider 39 slides, the pin-like member 24 a is in contact with the upper end surface of the stopper member 41 provided on the frame 33, so that the slider 39 is moved further backward. The nozzle 23 does not move downward even if it is slid. At this time, the winding conductor W drawn from the nozzle 23 is introduced into the slot 7 through a conductor guide slit 49 formed between the contact portions 45a and 47a of the pair of guide members 45 and 47. Further, the slider 39 moves rearward, and the pin-like member 24c provided at the upper end of the nozzle 23 engages with the long hole 64 of the nozzle engaging member 63 located rearward. In a state where the pin-like member 24 c is completely engaged with the long hole 64 of the nozzle engaging member 63, the pin-like member 24 a is completely separated from the upper end surface of the stopper member 41. As a result, the nozzle 23 has shifted from the third movement region to the second movement region. The operation of the nozzle in the third movement region is as shown in FIG.
[0031]
In the second movement region, the vertical driving force generator 59 moves the nozzle engaging member 63 downward, and the nozzle 23 is centered along a virtual straight line passing through the rear end surface and the center line CL. Move in a direction away from the line CL (first movement operation in the second movement region). Thus, the winding conductor drawn from the nozzle 23 is completely introduced into the slot 7. Next, the rotation mechanism 19 has a predetermined angle θ (an angle between the centers of two adjacent slots) in the other circumferential direction of the yoke of the core 3 with the frame 33 of the horizontal movement mechanism 17 as the center line CL. ) (The second movement operation in the second movement region). Thus, the nozzle 23 rotates by a predetermined angle θ in the other circumferential direction around the center line CL. Together with this rotation operation or after the rotation operation is completed, the needle 71 of the conductor alignment mechanism 67 engages with the winding conductor W drawn from the nozzle 23. The conductor alignment mechanism 67 operates the needle 71 so that the winding conductor is positioned at the alignment position. Thereafter, the vertical driving force generator 59 of the vertical movement mechanism 51 of the nozzle moving mechanism 15 moves the nozzle engaging member 63 upward, and moves the nozzle 23 along a virtual straight line passing through the front end surface and the center line CL. The nozzle 23 is moved in the direction (upward) toward the center line CL (third movement operation in the second movement region). The outline of the movement of the nozzle 23 in the second movement area is basically the same as the movement in the first movement area shown in FIG.
[0032]
Next, in order to move the nozzle from the second movement region to the first movement region, the nozzle 23 is moved in the third movement region. At this time, it moves along the inner opening of the other slot of the two slots located on both sides in the circumferential direction of one salient pole portion and without inserting the tip of the nozzle 23 into the other slot ( The second movement operation in the third movement area is performed). In the second movement operation in the third movement region, the air cylinder 43 as the slide driving force generator of the horizontal movement mechanism 17 moves the slider 39 from the rear position to the front position (from the right end to the left end in FIG. 1). . When the pin-like member 24c comes out of the long hole 64 as the slider 39 slides, the pin-like member 24a is in contact with the upper end surface of the stopper member 41 provided on the frame 33. The nozzle 23 does not move downward even if it is slid. At this time, the winding conductor W drawn from the nozzle 23 is introduced into the adjacent slot 7 through the conductor guide slit 49 formed between the contact portions 45a and 47a of the pair of guide members 45 and 47. Further, the slider 39 moves forward, and the pin-like member 24a provided at the upper end of the nozzle 23 engages with the elongated hole 62 of the nozzle engaging member 61 located in front. In a state where the pin-shaped member 24 b is completely engaged with the elongated hole 62 of the nozzle engaging member 61, the pin-shaped member 24 a is completely separated from the upper end surface of the stopper member 41. As a result, the nozzle 23 moves from the third movement region to the first movement region. The second movement operation in the third movement region is the same as the first movement in the third movement region shown in FIG. 6 except that the slot into which the winding conductor is inserted is different from the movement direction of the nozzle. Same as operation.
[0033]
As described above, the nozzle movement mechanism 15 repeats each movement area in the order of returning to the first movement area, the third movement area, the second movement area, the third movement area, and the first movement area. The winding portion is formed in the salient pole portion 9 without inserting the tip end portion of the nozzle 23 into the slot 7 by moving the nozzle 23 inside. This order does not necessarily mean that the winding operation must be started from the first movement region, but merely indicates the movement path of the nozzle 23. At the beginning of winding of the winding, the end of the winding is hooked on a winding conductor locking portion (not shown) provided outside the core 3. Therefore, the starting order of the above-mentioned movement path is determined by the position of the winding conductor locking portion outside the core.

When the nozzle 23 is moved by the nozzle moving mechanism 15 having the above-described configuration, the nozzle 23 moves along the inner opening of the slot 7 in the third movement region, so that the winding drawn from the tip of the nozzle 23 All or most of the conductor W enters the inside of the slot 7 from the inner opening 7 a of the slot 7. When the nozzle 23 moves in the first and second moving regions, the position of the winding conductor (or the distance from the center line) on the end face of the salient pole portion 9 located on the front end face and the rear end face of the core 3. ) Is determined by the movement of the needles 69 and 71.
[0035]
In the above example, the winding portion is formed by aligning and winding the winding conductor around the salient pole portion 9 using the conductor alignment mechanisms 65 and 67. However, the winding portion may be formed using only the nozzle moving mechanism 15 without using the conductor alignment mechanisms 65 and 67. In that case, in the first movement region and the second movement region, the movement amount of the nozzle 23 when performing the first movement operation and the third movement operation may be increased or decreased stepwise.
