Thus, when each data is inpotted in the control part, in the control part, the number of turns of the resistance wire 39 to the core 11 and the rotational speed and the slide base of the pulse motor constituting the supporting means rotating part 24 are shown. The rotational speed of the pulse motor 37 constituting the drive unit 36 is appropriately set, and it is determined how many times the resistance wire 39 is recommended with respect to the core 11 at an interval.

Next, the core supply unit 44 automatically moves the core 11 sent from the part feeder outside the city to a position where the chucks 22 and 22 can support the core 11.

That is, the core 11 placed on the core support arms 46 and 46 protruding forward of the core supply unit 44 through the lead wires 13 and 13 is an air cylinder constituting the core supply unit 44. As the 45 is operated, the pistons 48 and 48 are pushed forward by the drive unit 49, and the core support arms are formed by the U-shaped arm portions 47 mounted on the tips of the pistons 48 and 48. The core 11 supported by 46 extends forward to the axial center line positions of the chucks 22 and 22, and the arm portion 47 stops at that position.

Then, the chucks 22 and 22 are on the axial line of the chucks 22 and 22 by the core support arms 46 and 46 of the core supply section 44, as shown in the dotted line in FIG. In both ends of the lead wires 13 and 13 protruding from both ends of the core 11 supported in the hollow.

Then, as shown in FIGS. 4 and 6, the lead wires 13, 13 are inserted into the long holes 61, 61 provided along the axial direction inside the chucks 22, 22, and at the same time, , Both ends of the core body 66 are pressed against each other by the tips of the chucks 22 and 22 so that the core 11 is held by the chucks 22 and 22.

Thereafter, the air cylinder 45 of the core supply unit 44 is operated so that the piston 48 of the drive unit 49 retreats, and the arm portion 47 and the core support arm (which supported the core 11) ( 46) is returned to the current position, and the supply of the next winding 11 is prepared.

Next, as shown in FIG. 3 and FIG. 5, the drive part 83 which comprises the resistance wire supply nozzle retracting mechanism 26 is operated, and the resistance wire supply nozzle 77 is a right angle with respect to the core 11. FIG. While supporting the state, the front end side cap portion 12a of the core 11 has the resistance wire 39 projecting forward from the tip of the resistance wire supply nozzle 77 while the slide base 82 is pushed forward in the direction of the core 11. ) To the upper end of the main surface direction.

Thereafter, as shown in FIGS. 3 and 5, the electrode driver 28 provided in the upper welding electrode portion 73 and the lower welding electrode portion 74 constituting the welding electrode portion 19. 28 operates to move the upper electrode body 27a and the lower electrode body 27b through the arm parts 88 and 88 provided between the electrode driving units 28 and 28 and the electrodes 27a and 27b. Extrude

As a result, as shown in FIG. 7, the lower electrode main body 27b abuts against the lower end side of the tip side cap portion 12a of the winding core 11, and the upper electrode main body 27a and the upper electrode main body 27b. It contacts with the upper surface side of the tip shaft cap part 12a via the resistance wire 39.

Therefore, by energizing the upper electrode body 27a and the lower electrode body 27b in this state, the winding start portion 96 of the resistance wire 39 is connected to the front end cap portion 12a of the core 11. It is to weld on the upper surface side. Thus, these upper electrode bodies 27a and lower electrode bodies 27b are then retracted in the upper and lower direction of the core 11 by the operation of the electrode driving units 28 and 28.

Then, as shown in FIG. 1, the supporting means pivoting portion 24 constituting the supporting means 21 is operated to rotate the spindles 58 and 58, and the ends of the spindles 58 and 58 are rotated. In the present invention, the fixed core 11 is rotated by a predetermined rotational speed through the chucks 22 and 22. At the same time, the pulse motor 37 constituting the slide base drive unit 36 is operated to cause the feed screw unit 38 to rotate.

As a result, it starts to slide in the direction of the side plate frame 32b (right direction of FIG. 1) with the rotation movement of the feed screw part 38. As shown in FIG.

Therefore, as shown in FIG. 8, since the winding 11 is rotated in the state by which the chuck | zipper 22 and 22 was press-contacted by the rotational movement of the said spindles 58 and 58 in this way, the said winding core The resistance wire 39 on which the winding start portion is welded to the tip side cam portion 12a of (11) is continuously drawn out from the resistance wire supply nozzle 77, and further, the resistance wire supply nozzle 77 is a frame ( 68, and in the direction of the rear end of the core 11 along the axial direction of the core 11, the resistance wire (A) to the core body 66 of the core 11 at intervals initially inpotted in the control panel. 39) will be recommended by the enemy.

In this case, since the upper welding electrode portion 73 and the lower welding electrode portion 74 constituting the welding electrode portion 19 are fixed to the frame 68, the upper welding electrode portion The 73 and the lower welding electrode portion 74 move to the rear end side of the core 11 along the axial direction of the core 11 together with the resistance wire supply nozzle 77.

Then, as shown in FIG. 9, when the resistance wire supply nozzle 77 reaches the rear end of the core body 66 and welds the winding end portion 95 of the resistance wire 39, the core core part is wound. The rotational movement of the spindle portions 58, 58 constituting (17) is paused. Then, the resistance wire supply nozzle rotating unit 29 is operated, and the resistance wire supply nozzle 77 is rotated at a predetermined angle according to the movement direction of the resistance wire supply nozzle 77 with the electrode main body 27 as the center of rotation. By rotating by, the supply direction of the resistance wire 39 is changed.

That is, the drive part 84 which consists of the pulse motor which comprises the said resistance wire supply nozzle rotation part 29 rotates clockwise by the angle calculated by the inpot data previously, and the gear part 85 through the belt 40 is carried out. ), The cylindrical shaft portion 87 provided at the upper end portion is rotated by a predetermined angle in the direction. Thus, the mounting plate portion 76 provided on the upper end of the cylindrical shaft portion 87 is rotated clockwise by a predetermined angle around the lower electrode body 27.

As a result, as shown in FIG. 9, the resistance wire 39 located at the rear end of the winding main body 66 is pulled toward the rear end side of the winding core 11 by a predetermined angle, and the plane direction of the winding core 11 is shown. In the above, the rear end of the core 11 is arranged in an oblique direction.

Thereafter, the spindles 58 and 58 are rotated by a predetermined rotation speed, and the obliquely arranged resistance wire 39 ascends obliquely on the rear end side cap 12b of the core 11 to form the rear end side cam portion 12b. Position on an axial centerline on

Then, as shown in FIG. 10, again, the upper electrode body 27a and the lower electrode body 27b protrude from the body portions 75a and 75b constituting the welding electrode portion 19, The upper electrode body 27a contacts the upper surface side of the rear end cam part 12b with the resistor 39 disposed obliquely on the rear end cam part 12b, and at the same time, the lower electrode body 27b. And by the lower electrode portion 27b, the resistance wire 39 is sandwiched between the core 11 in a fixed state of the core 11.

Thereafter, first, the resistance wire nozzle retracting mechanism 26 of the tensioning means is operated, and the resistance wire supply nozzle 77 is started to slide backward on the slide base 82 by the moving part 83. Thereafter, the resistance wire fixing mechanism 25 is operated slightly behind the operation of the resistance wire retracting mechanism 26, and the resistance wire clamper 90 causes the resistance wire 39 to move the resistance wire 39 by the air cylinder 91. It is fixed in).

Then, as shown in FIG. 11, the resistance wire 39 is welded on the rear end cam part 12b by energizing the upper half electrode body 27a and the lower electrode body 27b. do. In addition, while the resistance wire 39 is welded by the upper electrode main body 27a and the lower electrode main body 27b, the resistance wire supply nozzle 77 is connected to the resistance wire 39 by the resistance wire clamper 90. Since the retraction is continued while the resistance wire 39 is fixed, the resistance wire 39 is melted by being pulled backward at the welding point in the rear end side cap portion 12b, whereby the winding resistor 10 is formed. will be.

Thus, after the winding resistor 10 is created, the electrode driving units 28 and 28 are operated to retreat once, the electrode main body 27a and the electrode main body 27b, and then the upper electrode main body 27a again. And the lower electrode main body 27b protrudes, and the rear end side main body 27b protrudes, and the created winding resistor 10 is pinched by the rear end side cam part 12b in the vertical direction. . After that, the supporting means drive unit 23 is operated again, and the spindle units 58 and 58 are moved toward the outside in the width direction of the automatic resistance wire recommender 16 according to the present embodiment, respectively, and the spindle ( 58, 58) The chucks 22, 22 provided at the front end are returned to their initial positions.

The winding resistor 10 held in the up and down direction by the upper electrode body 27a and the lower electrode body 27b, and supported in the hollow, then the electrode drive units 28 and 28 operate. As a result, since the upper electrode body 27a and the lower electrode body 27b retreat to release the pinch of the winding resistor 10, the winding resistor 10 falls downward, and the host part accommodating part ( It is stored in the fall).

Then, the new core 11 is automatically fed to the core support arms 46 and 46 provided at the tip of the arm portion 47 constituting the core supply unit 44 from the parts feeder outside the city, and thereafter the core core. By actuation of the drive part 49 constituting the supply part 44, the new core 11 comes forward by the arm part 47 until it reaches the axial center line positions of the chucks 22, 22 and the arm part 47. Stops.

Thereafter, the pair of means drive unit 23 includes the spindle units 58, 58 and the support unit rotating units 24, 24 provided at the rear end of the spindle unit 58, and the spindle units 58, 58. ) The chuck fixing portions 59 and 59 provided at the distal end portions and the chucks 22 and 22 provided at the chuck processing portions 59 and 59 are moved toward the inner side of the automatic resistance wire recommender 16. The chucks 22 and 22 are electrically and oriental, and the cores 11 supported in the hollow by the core support arms 46 and 46 of the core supply unit 44, as shown in the dotted line in FIG. Approach from both ends of the lead wires (13, 13) protruding from both ends of the. Then, as shown in FIG. 3, the lead wires 13 and 13 are inserted in the axial holes 61 and 61 provided along the axial direction in the chucks 22 and 22, and at the same time, the chuck ( Both ends of the core body 66 are pressed against each other by the tips of 22 and 22 so that the core 11 is supported by the chucks 22 and 22. Thereafter, as shown in FIG. 12, the resistance wire supply nozzle rotating unit 29 operates, and the resistance wire supply nozzle 77 rotates counterclockwise around the electrode body 27 as opposed to the above. It is in a state perpendicular to the axial direction of the core 11.

Then, as shown in FIG. 13, the retraction mechanism 26 of the resistance wire supply nozzle is operated so that the resistance wire supply nozzle 77 which has been retracted from the winding core 11 with respect to the winding core 11 with respect to the resistance wire ( 39) are forwarded to a recommended location.

In this case, as described above, at the time of welding the resistance wire 39 to the previous core 11, the resistance wire 39 is wound around the upper electrode body 27a and the lower electrode body 27b. After being fixed to (11), first, the resistance wire nozzle retracting mechanism 26 is operated, so that the resistance wire supply nozzle 77 slides to the rear side, and after that, it is slightly delayed so that the resistance wire fixing mechanism 25 causes the resistance wire ( Since 39 is melted by the electrode main body 27 in a fixed state in the resistance wire supply nozzle 77, the resistance wire supply nozzle 77 moves between them to the new core 11 at this time. The welding margin which becomes the winding start part 96 of the resistance wire 39 is secured.

Therefore, as shown in FIG. 12 and FIG. 13, winding of the resistance wire 39 starts to the front-end | tip part of the resistance wire supply nozzle 77 arrange | positioned in the state orthogonal to the axial direction of the core 11 in this way. Since the part 96 protrudes, the resistance wire supply nozzle 77 is moved forward, so that the winding start welding margin of the resistance wire 39 is formed on the upper surface side of the tip side cap part 12a of the core 11. 96) can be abutted.

Then, as shown in FIG. 13, the electrode drive parts 28 and 28 constituting the welding electrode part 19 operate to protrude the upper electrode body 27a and the lower electrode body 27b. The lower electrode main body 27a abuts against the upper surface side of the tip side cam part 12a with the resistance wire 39 interposed therebetween.

Then, by energizing the upper electrode body 27a and the lower electrode body 27b in this state, the winding start portion 96 of the resistance wire 39 is wound on the tip end cap portion 12a of the core 11. Weld on the upper surface side of. Thus, the upper electrode body 27a and the lower electrode body 27b are then retracted in the upper surface direction and the lower surface direction of the core 11 by the operation of the electrode driving units 28 and 28.

Thereafter, the support means pivot 24 operates in the same manner as the above, and rotates the spindles 58 and 58 to fix the cores 11 fixed to the ends of the spindles 58 and 58 via the chucks 22 and 22. ) Rotates a predetermined number of revolutions, and the pulse motor 37 constituting the slide base drive unit 36 is operated and rotates in the reverse direction from the previous welding of the core 11.

Accordingly, the frame 68 fixed to the feed screw portion 38 via the reverse threaded portion 55 is in a position near the side plate frame 32b, but is rotated by the feed screw portion 38. This slides back to the initial position and returns.

Therefore, in this manner, the winding core 11 rotates in a state of being pressed against the chucks 22 and 22 by the rotational movement of the spindles 58 and 58 as in the case of electricity, and thus the front end cap portion 12a of the winding core 11 The resistance wire 39, to which the portion 96 is welded, is continuously drawn out from the resistance wire supply nozzle 77. Moreover, the resistance wire supply nozzle 77 is wound together with the frame 68. The resistance wire 39 is recommended to the core body 66 of the core core 11 in the electrical orient direction because it moves in the direction of the rear end of the core 11 (left direction in the first diagram) along the axial direction of the core 11. .

Then, as shown in FIG. 14, when the resistance wire supply nozzle 77 reaches the rear end of the core body 66 and welds the winding end portion 95 of the resistance wire 39, the core core portion ( 17. The rotational movement of the spindle portions 58 and 58 constituting the 17 is temporarily stopped, and thereafter, the resistance wire supply nozzle pivoting portion 29 is operated in the same manner as described above, in accordance with the movement direction of the resistance wire supply nozzle 77. The supply line of the resistance wire 39 is changed by rotating the resistance wire supply nozzle 77 by a predetermined angle with the electrode main body 27 as the pivot center.

As a result, as shown in FIG. 15, the resistance wire 39 located at the rear end of the core body 66 is pulled toward the rear end side of the core 11 by a predetermined angle, and the plane direction of the core 11 is In the above, the rear end of the core 11 is arranged in an oblique direction.

Thereafter, the spindles 58 and 58 rotate again by a predetermined rotational speed, and the resistance wire 39 arranged at an angle rides obliquely near the rear end of the core 11 on the rear end cap 12b of the core 11. It is positioned on the axial center line of the rear end side cap portion 12b.

Thus, the upper electrode body 27a and the lower electrode body 27b protrude again, and the resistance wire 39 is connected to the core 11 by the upper electrode body 27a and the lower electrode body 27b. In the fixed state, the core 11 is pinched.

Thereafter, first, the resistance wire nozzle retracting mechanism 26 is operated so that the resistance wire supply nozzle 77 starts to retreat, and afterwards, the resistance wire fixing mechanism 25 is operated so that the resistance wire 39 becomes a resistance wire. The resistance wire 39 is welded onto the rear end cap 21b by being fixed in the supply nozzle 77 and then energizing the upper electrode body 27a and the lower electrode body 27b. .

Therefore, as shown in FIG. 16, the resistance wire 39 protrudes and arrange | positions to the front end of the resistance wire supply nozzle 77 in the state which left the welding allowance of the next winding start part 96 as shown above. .

Therefore, in the automatic resistance wire recommender 16 according to the present embodiment, the resistance wire 39 is continuously connected to the winding core 11 in any direction in the axial direction of the winding core 11 continuously supplied as described above. It can be recommended. In the automatic resistance wire recommender 16 according to the present embodiment, when the winding end portion 95 of the resistance wire 39 is welded as described above, the resistance wire supply nozzle 77 is connected to the resistance wire supply nozzle rotating unit. (29) is configured to rotate the electrode body 27 at a predetermined angle in accordance with the direction of movement of the resistance wire supply nozzle 77 with the electrode body 27 at the center of rotation. This is for welding after forming an almost complete contact state with the end-side cap portion 12b.

That is, as shown in FIG. 19, since the cap parts 12a and 12b are covered on both ends of the core body 66, the tip part is between the main surface of the core body 66 and the main surface of the rear end side cap part 12. FIG. A step is formed by the thickness of the side cap part 12a and the rear end side cap part 12b.

Therefore, when the resistance wire 39 is wound at right angles to the axial direction of the winding core 11 and welded to the rear end side cap part 12b at right angles to the axial direction in the same state, the resistance wire 39 is formed at the rear end side cap part. When the inner periphery 97 of 12b is wound over, the incomplete contact state between the periphery of the rear end cap portion 12b and the resistance wire 39 may be welded to the rear end cap portion 12b. have.

In this way, in the case where welding is performed while creating an incomplete contact state between the periphery of the rear end side cap portion 12b of the resistance wire 39, the electrical resistance of the resistance wire 39 of the portion where the incomplete contact state occurs is generated. It may become extremely unstable, and the precision of the resistance value of the winding resistor 16 as a product may fall.

However, in the automatic resistance wire recommender 16 according to the present embodiment, when the resistance wire supply nozzle pivoting portion 29 is provided and the winding end portion of the resistance wire 39 is welded, the resistance wire supply nozzle 77 is attached. The predetermined angle is rotated in accordance with the movement direction of the resistance wire supply nozzle 77 and the supply direction of the resistance wire 39 is changed to have a large angle with respect to the inner peripheral 97 of the rear end side cap portion 12b of the core 11. The resistance wire 39 is configured to be supplied.

Therefore, even when the resistance wire 39 crosses the inner periphery 97 of the rear end cap 12b, it is possible to ensure a nearly complete contact state between the resistance wire 39 and the periphery of the rear end cap 12. .

As a result, when the winding resistor 10 is produced using the automatic resistance wire recommender 16 according to the present embodiment, the resistance wire 39 is almost formed at the rear end side cap part 12b in the winding end portion 95. Since welding is carried out in a fully contacted state, stable electrical resistance can be ensured, and the resistance value can supply the winding resistor 10.

In the automatic resistance wire recommender 16 according to the present embodiment, the resistance wire supply unit 18 supports the resistance wire supply nozzle 77 to the winding core unit 17 with the electrode main body 27 as the center of rotation. The resistance wire supply nozzle rotating part 29 which can be rotated in any direction in the axial direction of the wound core 11 is provided.

Therefore, when the resistance wire supply nozzle 77 moves along the axial direction of the core 11 and welds the winding end 95, the resistance wire supply nozzle 77 is moved in the direction of movement of the resistance wire supply nozzle 77 at each time. ), The resistance wire 39 can be recommended to the core 11 together with the reciprocating movement of the resistance wire supply nozzle 77.

That is, the front end side of which the resistance wire supply nozzle 77 was covered by the core 11 along the axial direction of the core 11 by the enemy control before operation | movement of the automatic resistance wire recommender 16 which concerns on a present Example. While moving from the winding start position of the cap portion 12a to the winding end portion position of the rear end side cap portion 12b, a resistance wire 39 can be recommended for any winding core 11 at a desired pitch, and Without returning the resistance wire supply nozzle 77 to the starting position of winding, it is possible to start recommending the resistance wire 39 in a separate new winding 11 from the end of the winding of the resistance wire 39 of the winding core 11. Therefore, it is possible to finish the recommendation of the resistance wire 39 in a separate new winding 11 until returning to the start position of the original resistance wire supply nozzle 77.

Therefore, as shown in FIG. 17, even when the winding resistor 98 intersected by the resistance wire 39 is prepared, the automatic resistance wire recommender 16 according to the present embodiment can be easily prepared. It is possible.

That is, first, 39 is recommended in one direction in the axial direction of the winding core 11, and thereafter, while the resistance wire supply nozzle 77 returns to its original position, it is superimposed thereon and crossed at the same pitch. I can recommend it.

As described above, the winding resistor 98 recommended by crossing the resistance wire 39 is configured to prevent generation of noise caused by a magnetic field generated around the resistance wire 39, and is used, for example, in a VTR or the like. The winding resistor 98 recommended by crossing such a resistance wire 39 can be more easily produced by the automatic resistance wire recommender 16 according to the present embodiment.

In addition, as shown in FIG. 18, the thin wire is made of two resistance wires 39 in close contact with each other, and the winding resistance resistor 99 recommended at a predetermined pitch also uses the automatic resistance wire recommender 16 according to the present embodiment. This can be easily created.

In other words, while the resistance wire supply nozzles 77 move in one direction in the eastward direction, the resistance wires 39 are recommended to be spaced apart from each other at a predetermined pitch, and the resistance wire supply nozzles 77 return to their original positions. The second resistance wire 39 is recommended by being coupled to the wound resistance wire 39.

Such a winding resistor 99 can be used as a resistor having a low resistance. In the past, when a winding resistor having such a low resistance value is produced, a resistance wire having a large diameter is recommended.

However, when a winding resistor was produced using such a large resistance wire 39 as in the prior art, since the recommended spacing dimension between the resistance wires became very small, subsequent marking processing was impossible.

When a resistor having such a low resistance value is produced using the automatic resistance wire recommendation value 16 according to the present embodiment, the resistance wires are closely connected to each other using resistance wires having smaller diameters than resistance wires having a large number of scenic views. Since it can be recommended for the winding core 11, it becomes possible to easily produce the winding resistance machine of low resistance value which can be postmarked.

In the automatic resistance wire recommender 16 according to the present embodiment, as described above, the resistance wire supply nozzle pivoting portion 29 has the resistance wire supply nozzle 77 as the electrode body 27 as the pivot center. The cap part covered with the core 11 supported by the core core 17 is configured to be able to rotate in any direction in the axial direction of the core 11 supported by the core core 17. On the main surfaces 12a and 12b, the resistance wire 39 is supplied and arranged on the axial extension line of the upper electrode body 27a and the lower electrode body 27b.

Therefore, even when the winding end portion 95 of the resistance wire 39 is welded as described above, even when the resistance wire supply nozzle 77 is rotated in the direction of movement of the resistance wire supply nozzle 77, the resistance wire supply nozzle 77 ends. The resistance wire 39 supplied from the upper side is always disposed directly above the upper electrode body 27a on the cap portions 12a and 12b of the core 11, and as a result, the resistance wire 39 is certainly an electrode. The main body 27 is welded to the cap portions 12a and 12b of the core 11.

In this embodiment, an example is described in which the resistance wire supply nozzle rotating unit 29 can rotate the resistance wire supply nozzle 77 in any direction in the axial direction of the core, with the electrode body 27 as the center of rotation. However, the present invention is not limited to the above embodiment and may be configured to rotate in only one direction.

Since the automatic resistance wire recommendation machine which concerns on this invention is comprised as mentioned above, it can aim at the automation of the work which winds a resistance wire in a core, and can significantly improve the manufacturing efficiency of a winding resistor.

Moreover, since the automatic resistance wire recommender which concerns on this invention has the above structures, the lead wire fixed to both ends consists of winding cores which do not mutually match in an axial direction by manufacturing error, etc., or consists of the lead wire axis and an insulator. With respect to the core of the discrepancy of the core axis of the core body, it is possible to accurately recommend the resistance wire at a predetermined pitch.

In addition, when resistance wires are recommended for cores of different types, even if the diameter of the core lead wires is different, there is no need to change the core means of the core each time, and the resistance wire is always recommended by supporting the core with a single support means. In this way, the creation efficiency of the winding resistor can be improved.
