Description

  The present invention relates to a winding machine and a winding method for a multipole armature (mainly a motor core (including a linear motor core)).

  2. Description of the Related Art Conventionally, a winding machine has been widely used to wind a wire for forming a coil around a pole (core) of a multipole armature (motor core). In order to improve performance with a limited size of an armature such as a motor, how many windings can be formed in a limited winding space of a multi-pole armature (work) As required. For this purpose, so-called aligned winding, in which the wires adjacent to the pole are aligned and wound without any gap, is effective.

  By the way, in the case of an inner core type work (multi-pole armature) having a plurality of poles projecting radially inward from the yoke part forming the ring-shaped outer periphery, the slot increases as the number of poles increases (multi-pole). The width of (the gap between adjacent poles) becomes narrow. Therefore, if the moving distance (feed width) of the winding nozzle is limited, or if the wire for the winding contacts the adjacent pole, there is a possibility that sufficient aligned winding cannot be performed.

  In view of this, a method has been proposed in which an inner core type workpiece is wound around a straight core type workpiece developed in a strip shape (straight shape) and then bent into a ring shape (see Patent Document 1). In such a straight core type workpiece, the width of the slot is wide and the axial direction of the poles is parallel, so that the winding work by the nozzle is facilitated, and even a wire having a large wire diameter can be used.

  However, in a straight core type workpiece, the outer surface side (the side opposite to the pole) of the divided yoke part has a curved surface shape such as an arc surface, and the pole axes are not adjusted to be parallel to each other. As a result, the holding of the yoke (work) is not stable. Therefore, depending on the pole runout and the rattling of the yoke portion, the above-described aligned winding may not be possible, or a winding failure may occur. In such a case, the thicker the wire, the greater the force acting on the workpiece during winding, and the advantage of the straight core type (thick wire winding) cannot be utilized.

JP 2002-247788 A

  Further, even linear motor workpieces that have been actively developed in recent years may have straight yoke portions. In a straight yoke portion used for a linear motor, it is not necessary to bend it into a ring shape after winding, so that the outer surface side of the yoke portion can be formed flat from the beginning. However, even if the core is slightly misaligned or the rattling of the yoke is greatly affected by the motor performance after winding, it is necessary to hold the yoke (work) stably during winding as above. It becomes.

  An object of the present invention is to provide a winding machine and a winding method capable of improving winding accuracy by stably holding a workpiece having a straight yoke portion.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the winding machine of the present invention is
A yoke portion that has a predetermined length and is formed in a straight shape, a plurality of poles that protrude perpendicularly from the surface of the yoke portion and parallel to each other in the longitudinal direction, and tip ends of the poles A winding machine for winding a wire around each pole of a workpiece having a flange part formed respectively;
One or a plurality of nozzles wound around each pole of the workpiece while holding the wire rod by a circular movement around the axis of the pole and feeding in the axial direction;
One or a plurality of holders capable of holding the workpiece by contacting the selected collar portion from the axial direction with a collar portion corresponding to a pole selected from other than the pole in the winding by the nozzle. With
The holding tool is wound around the pole by the nozzle in a state where the workpiece is held by moving relative to the selection rod portion in the axial direction and contacting the selection rod portion. .

Further, in order to solve the above problems, the winding method of the present invention is:
A yoke portion that has a predetermined length and is formed in a straight shape, a plurality of poles that protrude perpendicularly from the surface of the yoke portion and parallel to each other in the longitudinal direction, and tip ends of the poles A winding method for winding a wire around each pole of a workpiece having a flange portion formed respectively,
One or a plurality of nozzles wound around each pole of the workpiece while holding the wire rod by a circular movement around the axis of the pole and feeding in the axial direction;
One or a plurality of holders capable of holding the workpiece by contacting the selected collar portion from the axial direction with a collar portion corresponding to a pole selected from other than the pole in the winding by the nozzle. With
A workpiece holding step of holding the workpiece by moving the holder relative to the selection rod portion in the axial direction and contacting the selection rod portion;
In a state where the work is held by bringing the holding tool into contact with the selection rod portion, the nozzle moves around the axis of the pole and feeds in the axial direction to each pole of the work. A winding process for winding wire,
A workpiece moving step of moving the holder relative to the workpiece in the longitudinal direction and changing the selection flange to be contacted;
It is characterized by including.

  According to such a winding machine (or winding method), during winding, the holding tool (for example, the holding tool) contacts the selected collar (the collar corresponding to the pole selected from other than the pole in the winding). In a state where the workpiece is held by (for example, pressing), the nozzle is wound around the pole. Therefore, the holder can reduce or eliminate pole wobbling (inclination of the axis) and rattling of the yoke part (raising in the axial direction, planar displacement, etc.) and stably hold the workpiece. The winding accuracy can be improved and aligned winding becomes possible.

  At this time, the flange corresponding to at least one of the poles located on both sides in the longitudinal direction across the pole in the winding with the nozzle is set as the selection flange, and the holder contacts each of the selection flanges from the axial direction.・ It is desirable to hold. Since the holder contacts (for example, presses) the flanges on both sides across the pole in the winding, the workpiece can be held stably, and even when winding with multiple nozzles at the same time, the pole runout and yoke part It becomes difficult to generate a decrease in winding accuracy due to rattling.

  In addition, if such a holding tool is formed wider than the width in the longitudinal direction of one selected hook part so as to be able to contact the selected hook part with the full width in the longitudinal direction, the work can be held by the holder. Is more stable.

  In addition, the holder moves relative to the workpiece in the axial direction when it is wound on each pole, contacts the selected collar, and every time the winding on each pole is finished, the holder is moved in the longitudinal direction. The selection collar to be contacted can be sequentially changed. As a result, as the winding pole moves, it is only necessary to sequentially shift the selection hooks to be contacted (pressed) in the longitudinal direction, so that the longitudinal length of the holding tool can be shortened, and consequently the winding. The wire machine can be downsized.

  A plurality of nozzles are provided corresponding to the number of phases of the workpiece, and windings are simultaneously performed on the poles corresponding to each phase, and a plurality of nozzles are arranged between the poles in the winding. Each of the collars corresponding to at least one of these is a selection collar, and the holder can be in contact with the selection collars. As a result, the holder can be reliably disposed between the plurality of nozzles, so that the workpiece can be held more stably.

  When the auxiliary holder for holding the yoke part is arranged on the opposite side of the axial direction with respect to the holder, rattling of the yoke part (raising in the axial direction, plane deviation) Etc.) can be further reduced, and the workpiece can be positioned reliably.

In order to solve the above-described problems, the winding machine of the present invention has a specific aspect,
A yoke portion having a predetermined length in the horizontal direction and formed in a straight shape, a plurality of poles projecting vertically from the surface of the yoke portion and parallel to each other along the longitudinal direction, and the poles A winding machine for winding a wire around each pole of a workpiece having a flange part formed at each end part,
A plurality of nozzles wound around each pole of the workpiece while holding the wire rod by a circular movement around the vertical axis of the pole and feeding in the axial direction;
The flanges corresponding to the poles located on both sides of each nozzle across the poles in the windings can be selected as the selection flanges, and the selected flanges can be pressed from above to hold the workpiece in a horizontal state. A plurality of holders, and
The holder is moved up and down in the axial direction with respect to the selected hook part and pressed against the selected hook part to hold the workpiece in a horizontal state, and simultaneously wound around each pole by the plurality of nozzles. It is characterized by a line.

  As described above, at the time of winding, a holding tool (for example, a holding tool) holds the workpiece by pressing the selected hook part corresponding to the poles adjacent to the poles in the winding from above. Therefore, even with a relatively small pressing force, it is possible to prevent the occurrence of pole runout and rattling of the yoke portion, so that winding accuracy is improved and aligned winding is possible.

Example 1
Hereinafter, embodiments of the present invention will be described with reference to examples shown in the drawings. FIG. 1 is an overall side view of a winding machine according to the present invention. As shown in FIG. 1, on a base 1 of a winding machine 100, a workpiece support frame 3 that horizontally supports a workpiece 19 that is a straight core type multipole armature described later, and a wire W on the workpiece 19. The nozzle support frame 2 for supporting the nozzle 20 for winding and the nip support frame 4 for supporting the nip portion 46 for holding the tip end portion (start end portion and / or end end portion) of the wire W are respectively mounted and fixed. ing. A presser support frame 35 (holding tool support frame) that supports a work presser 31 (holding tool) for pressing the collar portion 19t (teeth) of the work 19 is integrally fixed to the work support frame 3. Has been. Further, a nipper support frame 45 (cutting tool support frame) that supports a nipper 41 (cutting tool) for cutting the wire W after the end of winding is integrally fixed to the nip support frame 4. A pulley 39 (reel) for supplying the wire W to the nozzle 20 is disposed on the presser support frame 35.

  A left / right movement motor 5 is fixed to the nozzle support frame 2, and the left / right movement motor 5 includes a linear rail 6 a fixed to the nozzle support frame 2 and a linear guide 6 b fixed to the lower portion of the left / right movement frame 7. Relatively move horizontally in the left-right direction (direction perpendicular to the page). A front / rear moving motor 8 is fixed to the left / right moving frame 7, and the front / rear moving motor 8 includes a linear rail 9 a fixed to the left / right moving frame 7 and a linear guide 9 b fixed to the lower part of the front / rear moving frame 10. Are moved horizontally relative to each other in the front-rear direction (a direction orthogonal to the left-right direction and advancing and retreating with respect to the workpiece 19). Further, a vertical movement motor 12 is fixed to a support frame 11 that extends vertically from the front and rear movement frame 10, and the vertical movement motor 12 holds the linear rail 13 a fixed to the support frame 11 and the nozzle 20. The linear guide 13b fixed to the nozzle bracket 14 is relatively moved in the vertical direction (vertical direction).

  That is, the left / right moving motor 5 slides the left / right moving frame 7 in the left / right direction, and the front / rear moving motor 8 slides the front / rear moving frame 10 in the front / rear direction. The core moves around the axis O in the vertical direction. Further, when the vertical movement motor 12 slides the nozzle bracket 14 in the vertical direction, the nozzle 20 moves in the direction of the axis O of the pole 19c of the workpiece 19 by the wire diameter of the wire W every round of the axis O around the axis O. Sent. Therefore, when the workpiece 19 is a multi-phase multi-pole armature, a plurality of nozzles 20 (three here; see FIG. 2) are provided corresponding to the number of phases of the workpiece 19 (for example, three phases), and the vertical axis The wire W is simultaneously wound while holding the wire W for every 12 poles 19c corresponding to each phase of the workpiece 19 by the circular movement around the O and the feed in the direction of the axis O.

  On the other hand, a workpiece moving motor 15 is fixed to the workpiece support frame 3, and the workpiece moving motor 15 includes a linear rail 16 a fixed to the workpiece support frame 3 and a linear guide 16 b fixed to the lower portion of the workpiece mounting base 17. Are horizontally moved in the left-right direction (direction perpendicular to the paper surface). Therefore, each time the winding of the work 19 to each pole 19c by the three nozzles 20 is completed, the work 19 slides in the left-right direction by one pitch (one pole) and moves to the next (adjacent) each pole 19c. Are wound (see FIG. 5).

  By the way, the workpiece 19 used in this embodiment is a straight core type multi-pole (here, 12 poles) armature in which the inner core type is developed in a strip shape (straight shape). Therefore, as shown in FIG. 5, the lower surface of the work 19 has a shape in which a plurality of (three phases × 4 = 12) yoke portions 19y that are curved are connected in the longitudinal direction, so that the yoke portion 19y itself lacks stability ( At the same time, the axis O of the twelve poles 19c is inclined, and the collar portion 19t (tooth) contacts the nozzle 20 during winding, thereby preventing the aligned winding.

  Accordingly, the presser support frame 35 is pressed from above by the flanges 19t (selection flanges) corresponding to the poles 19c adjacent to both sides of the pole 19c in the winding with the nozzle 20 from above. A plurality of (for example, four) work pressers 31 (holding tools) that can be held in a horizontal state are arranged (see FIG. 2). Further, in the work support frame 3, a work clamp 51 (secondary member) for holding the yoke portion 19y of the work 19 on the lower side of the pole 19c (on the opposite side of the work clamp 31 with respect to the work clamp 31 in the axis O direction). A holder) is arranged (see FIG. 3).

  The nip portions 46 supported by the nip support frame 4 and the nippers 41 supported by the nipper support frame 45 are respectively arranged in the same number as the nozzles 20 (here, three; see FIG. 4A). Yes.

  With reference to FIG. 2, the workpiece pressing device 30 including the workpiece pressing tool 31 will be further described. A work presser 30 shown in FIG. 2 includes a total of four work pressers 31 arranged along the longitudinal direction of the work 19, and a connecting plate 32 (connecting part) that supports and suspends these work pressers 31. And a pair of air cylinders 33 and 33 (work press drive source) that are attached to the presser support frame 35 and move the work presser 31 (connecting plate 32) closer to and away from the work 19 by expansion and contraction thereof. Reference numeral 34 denotes an elevating guide for the work pressing device 30 installed in parallel with the air cylinder 33. In addition, as shown in FIG. 2A, in the vertical movement of the work retainer 31, in addition to the lowered position L for pressing the work (for example, to the air cylinder 33) and the raised position H for replacing (removing) the work. If the intermediate position M for moving the workpiece (moving the pole to be wound) is provided in the winding, the winding time can be shortened.

  Specifically, the work 19 in FIG. 2 is configured as a three-phase 12-pole armature. In FIG. 2A, the third, seventh, and eleventh from the left by three nozzles 20, 20, 20. It shows that winding is simultaneously performed on the pole 19c. At this time, the work presser 31 presses the flanges 19t corresponding to all the non-winding poles 19c located between the winding poles 19c. That is, in the case of FIG. 2 (a), the four work pressers 31, respectively, with the first and second, fourth to sixth, eighth to tenth, and twelfth collars 19t from the left as the selection collars. It is pressing at 31, 31, 31 simultaneously. As a result, the workpiece 19 can be stably held in a horizontal state, so that the three nozzles 20, 20, and 20 can simultaneously wind the third, seventh, and eleventh poles 19c from the left. In this way, the work presser 31 can be in contact over the three 19t flange portions (is formed wider than the longitudinal width of one hook portion), so that the workpiece 19 (yoke portion 19y) is lifted. It is difficult to cause rattling.

  With reference to FIG. 3, the workpiece | work clamping apparatus 50 containing the said workpiece | work clamp 51 is further demonstrated. A workpiece fastening device 50 shown in FIG. 3 is interposed between a workpiece clamp 51 (work holder) disposed on the workpiece mounting base 17 along the longitudinal direction of the workpiece 19 and between the workpiece mounting base 17 and the workpiece clamp 51. It has a pair of air cylinders 53 and 53 (work clamp drive source) for moving the work clamp 51 away from and approaching the work mount 17 by expansion and contraction.

  The wire cutting device 40 including the nipper 41 will be further described with reference to FIG. The wire rod cutting device 40 shown in FIG. 4 includes three nippers 41 arranged along the longitudinal direction of the workpiece 19, a connecting plate 42 (connecting portion) that supports and supports these nippers 41, and a nipper holding frame 45. And a pair of air cylinders 43 and 43 (nipper driving sources) for cutting the wire W while moving the nipper 41 closer to and away from the wire W wound around the work 19 by expansion and contraction. Reference numeral 44 denotes an elevating guide of the wire rod cutting device 40 installed in parallel with the air cylinder 43.

The nozzles 20, 20, and 20 move around the axis O while drawing a locus such as a rectangular shape, an elliptical shape, or an oval shape along the cross-sectional shape of the pole 19c (the flange portion 19t).

[3] Workpiece moving step (1) With the air cylinders 53 and 53 (work clamp 51; see FIG. 3A) being tightened and held as they are, the air cylinders 33 and 33 are driven to reduce, and the work presser 31 is moved in the axis direction. Retreat to the intermediate position M above the O direction (see FIG. 2A) to release the pressing of the collar portion 19t.
(2) The workpiece moving motor 15 is driven, and the workpiece mounting base 17 is moved by one pitch in the longitudinal direction (to the left in FIG. 6) and stopped. At this time, the nip portions 42, 42, 42 release the holding of the S line (start line).
(3) The air cylinders 33 and 33 are driven to extend, the work retainer 31 is lowered from the upper side in the axis O direction to the lowered position L (see FIG. 2 (a)), and the flange 19t is pressed, so that the work 19 is horizontal. Hold on. As shown in FIG. 6, at this time, the four workpiece pressers 31 simultaneously use the first, third to fifth, seventh to ninth, eleventh and twelfth collars 19t from the left as the selection collars. Pressing.

[4] Next winding step (1) The work moving motor 15 is stopped, the air cylinders 53 and 53 are reduced and the air cylinders 33 and 33 are extended.

The nozzles 20, 20, and 20 have the same trajectory as in the winding process.
(3) In this way, the “work moving process” and the “next winding process” are repeated. The number of repetitions is 4 in the case of 3 phases and 12 poles.

[5] F-line cutting step (1) The left-right movement motor 5 and / or the front-rear movement motor 8 are driven to move the three nozzles 20, 20, 20 at the same time, and the three wire rods W, W, W Are inserted into the corresponding nip portions 42, 42, 42 as F lines (finish lines).
(2) The air cylinders 43, 43 are extended and driven, the nippers 41, 41, 41 are brought close to the wire rods W, W, W wound around the work 19, and the wire rods W, W, W are cut as F lines. At this time, the wire rods W, W, W remaining between the nip portions 42, 42, 42 become S lines (start lines) when winding the next workpiece.

  In this way, at the time of winding, the work presser 31 holds the work 19 by pressing the hooks 19t (selected hooks) corresponding to the poles 19c adjacent to the poles 19c in the winding from above. Therefore, even with a relatively small pressing force, it is possible to prevent the pole 19c from running out of the core (inclination of the axis O) and the rattling of the yoke portion 19y (lifting in the direction of the axis O, planar deviation, etc.). Accuracy is improved and aligned winding becomes possible. In the workpiece moving step, the workpiece presser 31 and the nozzle 20 may be moved in the longitudinal direction of the workpiece 19 instead of moving the workpiece mounting table 17 or together with the movement of the workpiece mounting table 17.

(Example 2)
As shown in FIGS. 1 and 7, when the single-phase work 19 is wound with the single nozzle 20, the work presser 31 can be operated as follows. In FIG. 7, No. (round numeral) attached to the flange 19t indicates the winding order. The differences from the first embodiment are mainly as described below.

[1] Workpiece holding step (3) The air cylinders 33 and 33 are driven to extend, the pair of left and right work pressers 31 are lowered from above in the direction of the axis O to press the flange portion 19t, and the work piece 19 is held horizontally. . As shown in FIG. 7A, at this time, the left end of the pair of left and right work pressers 31 is detached from the work 19, and the other work presser 31 is the second (No. 5) collar from the left. 19t is pressed as a selection collar.

[2] Winding step (3) The left and right moving motor 5 and the front and rear moving motor 8 are driven, and the circular movement around the axis O of the pole 19c by the single nozzle 20 and the vertical moving motor 12 are driven. As shown in FIG. 7A, the wire W is wound around the first pole 19c from the left (No. 1) by feeding the nozzle 20 in the direction of the axis O. The nozzles 20, 20, and 20 move around the axis O while drawing a locus such as a rectangular shape, an elliptical shape, or an oval shape along the cross-sectional shape of the pole 19c (the flange portion 19t).

[3] Workpiece moving step (2) The work moving motor 15 is driven, and the work mount 17 is moved in the longitudinal direction by three pitches (to the left in FIG. 7B) and stopped. At this time, the nip portion 42 releases the holding of the S line (start line).
(3) The air cylinders 33 and 33 are extended and driven, the work presser 31 is lowered from above in the direction of the axis O to press the flange 19t, and the work 19 is held horizontally. As shown in FIG. 7 (b), at this time, the pair of left and right workpiece pressers 31 simultaneously press the third (No. 9) and fifth (No. 6) brim 19t from the left as the selection bristle. ing.

[4] Next Winding Step (2) The left / right moving motor 5 and the front / rear moving motor 8 are driven, the single nozzle 20 makes a circular movement around the axis O of the pole 19c, and the up / down moving motor 12 By driving and feeding in the direction of the axis O by the nozzle 20, the wire W is wound around the fourth (No. 2) pole 19c from the left, as shown in FIG. 7B. The nozzles 20, 20, and 20 have the same trajectory as in the winding process.
(3) In this way, the “work moving process” and the “next winding process” are repeated. As shown in FIG. 7C, the number of repetitions is the same as the number of poles 19c (for example, 12 in the case of a single-phase 12-pole).

  In addition, in the single-phase work 19 in which the winding is completed as shown in FIG. 7C, the winding is cut between the No. 4 pole and the No. 5 pole, and the No. 8 pole and the No. If the winding is cut between 9 poles, it can be used as a three-phase armature of No. 1 to No. 4, No. 5 to No. 8, and No. 9 to No. 12.

(Modification)
FIG. 8 shows a modification of the work presser. As shown in FIG. 8A, the work presser 31 may be installed by being divided into a plurality of parallel rows (for example, two rows) across the longitudinal center line of the work 19.

  Further, as shown in FIG. 8B, a work presser 31 that presses the flange portion 19 t corresponding to the pole 19 c adjacent to both sides across the pole 19 c being wound by the nozzle 20 from above is provided on the work 19. They may be connected and integrated on one side in the longitudinal direction.

  In the above description, only the case of using a straight core type multi-pole armature as a workpiece has been described. When the workpiece 19 is a multi-pole armature for a linear motor having a straight yoke portion 19y, the yoke portion 19y is formed in a flat plate shape without being bent in FIG. Although the sticking is difficult to occur, the phenomenon in which the aligned winding is hindered due to the axis O of the pole 19c (core) being inclined obliquely or the flange 19t (tooth) contacting the nozzle during winding also occurs. Therefore, the present invention can be similarly applied even when a multi-pole armature for a linear motor is used as a workpiece.

  In addition, for example, it is possible to change the shape of the workpiece or the like by appropriately connecting a line processing state (process) such as a binding line or a crossover as necessary.
