The core holding unit 141 enters the holder 74 of the riser 15. Next, by the action of the rising part 15, the core holding unit 1
41 rises and reaches the upper stage. Up to this point, the empty holder 73 has risen and returned to the upper stage again. After each work process at the work station 13 is completed, the core holding units 141, 14a, 14b are moved by the unit transfer mechanism.
, 14c move rightward to the next station, and the core holding unit 14d is accommodated in the holder 73. In this way, the core holding unit 14a and the like are transferred one step, and this process is repeated to manufacture the coil element 2. The horizontal movement of the upper and lower stages of the core holding unit 14a, etc. is performed by the frame 9 in the U-shaped groove on the lower surface of the upper frame 97.
It is guided by a convex line on the upper surface of 9 and a convex line on the upper surface of the lower U-shaped groove frame 102.

The middle frame 99 extends from the base 11 to the bracket 104 (

The gear 168 rotates together with the gear 167.
It meshes with a gear 169 provided at the shaft end of the pulse motor 154, and has a wide tooth width so that it will not become disengaged even when the movable block 159 reciprocates.

As the movable block 159 advances, the rack 37 such as the core holding unit 14b is pushed in by the pusher 180 and removed from the gear 35, and then the gear 168 meshes with the gear 35 instead and receives rotation from the pulse motor 154. This is for transmitting the information to the winding shaft 24. Center pin 17
3 is the core holding unit 14b by contact with the movable block.
Push the rear end of the push rod 32 of the winding shaft 24 such as the L wire 44.
The wire 44 is connected to the core 21 and the push rod 3 as shown in FIG. 19 with a gap on both sides as shown in FIG.
It is designed to be held by sandwiching the ends of the two. As will be described later, the outer slope 178 of the opening/closing claw 28 comes into contact with the winding and serves to slide the wire 44 into the winding groove 177. The push pin 174 pushes the rear end of the slide shaft 39 (FIGS. 6 and 7) of the core holding unit 14b, etc.
It is for cutting the wire 44 as described above with respect to the figures.

The push pin 176 is the push rod 3 of the core holding unit 14c installed at the wax station 19, which is the next process.
2 to open the winding groove 177 of the core 21 as shown in FIG.
This is to project a predetermined distance D from the tip of the opening/closing claw 28 so that the opening/closing claw 28 does not interfere with wax application.

As the cam 164 rotates, the movable block 159 moves forward, and the center pin 173 first pushes the head 34 of the push rod 32 to sandwich the wire 44 between the core 21 and the push rod 32 as shown in FIG. The wire 44 is cut by the cutter 42 under the action of the pin 174 (FIGS. 7 and 8), and at the same time or afterwards the gear 168 meshes with the gear 35 instead of the rack 37, and in this state the stroke of the movable block 159 is controlled by the limit switch 179. Detected by pulse motor 1

Attach the cut end at the start of winding to flange 4 as shown in Figure 8.
5 and the push rod 32 and stretched horizontally, the wire 44 slides by the slope 178 on the outside of the opening/closing claw 28 and into the winding groove 177 of the core 21, and the winding of the coil is removed. It is about to start. The pulse motor 154 is configured to stop after the take-up shaft 24 has rotated a predetermined number of times. Next, the function of the wax station 19 will be explained.

Watuku Ste. - In the section 19, as shown in FIG. 21, a slide rod 182 and the like are slidably supported by a sleeve 181 provided on the middle frame 99 by the action of a cam 187.

Due to the reciprocating movement of the slide rod 182, etc., the tip of the wax applicator 194 moves to E=F#G= in FIG.
It moves in a trajectory H, deposits the wax stored in the wax container 196, covers the winding groove 177 (FIG. 8) of the core 21 at the position H, and is wound. Wax is applied to the part of the coil where the coil is located. 199 is a deformed pin attached to the housing 190, and when the housing 190 approaches the core holding unit 14c etc., the 42nd
As shown in Figure A, this is for performing upward plastic bending deformation on the wire 44 stretched between the core 21 and the guide rollers 55, 56.

This upward bending deformation causes the next karage station 20
It is processed to make it easier to carry out work. Next, the operation of the karaage station 20 will be explained.

In the karaage station 20, as shown in FIGS. 25 to 28, slide rods 201, 202, and 203 are slidably supported by a sleeve 200 provided on the middle frame 99 by the action of a cam 207.

Due to the reciprocating movement of the slide rod 201 and the like, the wire retainer 225 supported from the middle frame 99 rotates, and the cutter 214, push rod 219, and push pin 226 reciprocate. The wire retainer 225 is lifted by the cam 208 to allow the core 21 to pass through when the slide shaft 222 is rising, as shown in FIG.
When the core 22 is lowered, it comes into contact with the flange 45 of the core 21, as shown in FIG. The position of contact is a small distance J above the center of the core 21, as shown in FIG. 226 is a push pin provided on the slide rod 201 via a spring 227;
This is for pushing the rack 53 such as the core holding unit 14d and rotating the guide rollers 55, 56 around the pin 48 (FIGS. 3 and 5).

When the guide rollers 55, 56 rotate, the wire 44 is bent in the opposite direction and is hung around the flange 45 as shown in FIG. FIG. 33 shows the tip of the cutter 214, and a push rod 228 is placed in the center of the cutter 214, which has a semicircular cross section.
is pressed by a push spring (not shown) from the cutter 214.

When the cutter 214 is brought close to the core 21, the push rod 228
The contact wire 44 is pressed against the recess in the end face of the flange 45 to make it concave, and the cutter 214 cuts the wire at point K while compressing the spring. push rod 2
19 is the next step, pushing the clamp 30 of the core holding unit 14e located at the upper stage of the lowering part 16 and opening/closing the opening/closing claw 28.
The wire 44 is wound around the core 21 to release the completed coil element.

Next, a mechanism related to the wire 44 will be explained.

As shown in FIG. 2, the wire 44 is led out from a wire reel 274, passes through a tensioning mechanism 275 that applies tension to the wire 44 on the work station 13 side, and then passes through the guide roller 27.
6 makes it horizontal. Tension mechanism 27 as shown in FIG.
The wire 44 coming out from the wire guide 139 of the supply station 17 passes through the guide hole 140 of the wire guide 139 of the supply station 17, but the wire 44 is passed through the guide hole 140 of the wire guide 139 of the supply station 17. The wire 44 is moved away as shown at 44', and the core holding unit is returned to the position 139 after being placed in the home position 14a. At the supply station 17, the wire 44 is separated from both the push rod 32 and the core 21, as shown in FIG.

(When winding is performed at the winding station 18, this wire 44 moves at high speed.) In the winding station 18, the wire 44 is held between the push rod 32 and the core 21 as shown in FIG. In this case, in order to perform close winding, the wire approach angle β is preferably 1 to 5 degrees, more preferably 2 to 3 degrees. The cam 277 shown in FIGS. 37 and 38 (and FIG.
, the distance R between the guide roller 56 and the guide roller 55 is increased, and the wire 44 located between them is released to allow passage during winding, and when transferred to the next process, the wire 44 is This is for holding the rollers between the guide rollers 55 and 56.

Although the functions of each part have been generally described above, the overall function will be explained according to the steps.

In the flow shown in FIG. 10, the empty core holding unit is transferred to the upper stage of the rising part 15 by the unit return transfer mechanism, and is sent horizontally by the unit transfer mechanism to enter the supply station 17, where it is held by the positioning pin 61. It is set in the normal position and becomes the state 14a.

During this process, the wire 44 is temporarily moved away from the core holding unit 14a by the movement of the wire guide shown in FIG. 34 so as not to interfere with the core holding unit 14a. In the supply station 17 , the cores 21 housed in the chute 136 are supplied one by one to the core receiver 133 , and the cores 21 are pushed by the push rod 130 into the opening/closing claw 28 opened by the push rod 138 . sandwiched between. At this time, the wire 44
As shown in FIGS. 5 and 35, it is in a state where it can freely pass through without touching either the push rod 32 or the core 21. Next, by the unit transfer mechanism, it enters the winding station 18 and becomes a core holding unit 14b.

At this time, the wire 44 is moved to the guide roller 55 of the core holding unit 14c, which moves to the next wax station 19.
56, the push rod 32, and the core 21 and are pulled. At the winding station 18, first the cam 27
7, the distance between the guide rollers 55 and 56 is widened so that the wire 44 is not restricted, and then the push rod 32 is pushed to sandwich the wire 44 between the core 21 and the push rod 32, and then the cutter 42 is used to remove the wire 44. Cut 44. At this time, the tension mechanism 275 does not apply tension to the wire 44 of the core holding unit 14c in the wax station 19, but in addition to being held between the push rod 32 and the core 21, the wire 44 is also held between the guide rollers 55 and 56. Therefore, the wire 44 will not come loose. Next, gears 168 and 35 mesh,
When the pulse motor 154 is activated, the winding shaft 24 rotates, and the wire 44 passing through the slit 27 slides on the slope 178 of the opening/closing claw 28 and is wound into the winding groove 177. After performing a predetermined rotation, the pulse motor 154 stops. Next, it is transferred by a unit transfer mechanism and becomes a core holding unit 14c at the wax station 19.

When the wax station 19 is turned off, the core 21 is first pushed out a little by the push pin 176 of the winding station 18, and the winding groove 177 is separated from the opening/closing claw 28. Next, the wax applicator 194 holding wax moves to apply wax to the surface of the coil wound in the winding groove 177 of the core 21. At the same time, the wire 44 is bent upward by the deforming pin 199 as shown in FIG.
Next, the core holding unit 14d is transferred again to the carage station 20 by the unit transfer mechanism.
becomes the state of

In the karaage station 20, first, the wire retainer 225 descends and its tip hits the flange 45 of the core 21. Next, the guide rollers 55 and 56 rotate around the pin 48 (FIGS. 5 and 34) to fold back the wire 44 as shown in FIG. 32. At this time, the wire 44 is connected to the flange 4.
In order to prevent the wire 44 from slipping on the lower side of the wire 5, the wire 44 is bent upward by the deforming pin 199 as described above in FIG. The folded wire 44 is pushed into the recess by a push rod 228, as shown in FIG. 33, to help ensure soldering. After that, it is cut with a cutter 214. Since the cutter 214 is semicircular, the wire 4
Even if the outlet 4' is slightly shifted, cutting can be performed reliably. In this way, the coil element 2 is completed, but at the karaage station 20, the push rod 219 is used to open the opening/closing claw 28 of the core holding unit 14e in the next step.

Next, it is sent to the descending section 16 by the unit transfer mechanism and becomes a core holding unit 14e.

Here, the push rod 219 of the karaage station 20
As a result, the opening/closing claw 28 opens and the coil element 2 is released.
At the same time, as shown in FIG. 2, this coil element 2 is pinched by the pinching mechanism 231 of the coil element transfer mechanism 10, and the rotating shaft 230 is rotated 180 degrees to transfer the coil element 2 to point L on the opposite side, and the coil element 2 is transferred to the point L on the opposite side. The mounting station 266 is lowered to a point N between the open ends of the lead wires 1, and the insertion plate 269 is inserted between the lead wires 1 to sandwich the coil element 2 between the open ends of the lead wires 1. The electronic component series 6 is transferred to the next process by a one-pitch feeding mechanism. According to the present invention, each work station can be circulated efficiently, and the processing work that is involved in each work station can be performed quickly and reliably, eliminating wasted time between processes and greatly increasing the work efficiency of coil manufacturing. This eliminates the need for storage space for intermediate products, making the entire coil manufacturing equipment more compact, preventing damage to the coils during handling, and greatly contributing to improving the capacity and reliability of the coil manufacturing equipment. Since the entire base frame can be moved in a straight line, many machining operations can be carried out smoothly at many work stations.Also, since the core clamping mechanism and the drive unit are located on the opposite side of the base frame, both sides can be moved smoothly. It is possible to provide a core holding device for coil manufacturing that can effectively utilize the energy and make the coil manufacturing device compact, and has an extremely large practical effect.
