Description

[Detailed description of the invention] This invention relates to the improvement of a core winding device, particularly for the portion including the core hole of a minute core (chip) used in magnetic heads of electronic computers, video tape recorders, etc. The main objective was to make the structure more compact and thereby reduce costs.

To explain with reference to the drawings, the core winding device according to the invention includes a core holder (core holding block).
30, wire supply block 40, wire end clamp 50,
Wire suction pipe head (nozzle) 60, winding guide 70, winding auxiliary guide 80, wire end transfer block 90, and wire tension air flow generation nozzle 100
It consists of eight means.

Specifically, the core holder 30 is a means for horizontally holding the core 20 with the winding part (generally the head part) including the core hole 22 protruding outward. At the top, the part adjacent to the winding part (generally the body part) of the core 20,
It can be configured such that it is held directly or indirectly via a set screw 34 or the like.

The wire supply block 40 is a means installed above the core holder 30 so as to be movable up and down in order to supply the required amount of wire 10 to the core 20 held in the core holder 30 from above through the core hole 22. It includes a roller 42 and a wire cutter 44 installed below the roller. This line supply block 40
The vertical movement of the block can be achieved, for example, by forming it as a lifting block that can be moved up and down via a belt or the like.

Next, the wire end clamp 50 is connected to the wire supply block 40.
10 parts of the wire extending between the core 20 and the core 20
It is a means for clamping at an upper side position, and is installed near the core holder 30 so as to be able to move toward and away from the core holder 30. This line end clamp 50 is
For example, a wire hooking arm 52 that has a rotating shaft driven by a motor 54 on a side part of the core holder 30 and whose tip end can rotate across directly above the core hole 22 of the core 20; It can be constructed by a wire presser foot 56 (for example, composed of an electromagnetically actuated plunger) that can be press-engaged with the tip of the wire hooking arm 52.

The wire suction pipe head 60 connects the wire 10 extending downward through the core hole 22 of the core 20 to the core hole 22.
The core holder 30
It is installed below so that it can be moved up and down. The vertical movement of the line suction pipe head 60 can be achieved, for example, by attaching it to a lifting block that can be moved up and down via a belt or the like. The wire suction pipe head 60 can be connected to a vacuum pump via, for example, a flexible tube or a waste wire reservoir (tank).

On the other hand, the winding guide 70 is connected to the core hole 22 of the core 20.
The wire 10 extending downward through the core hole 22 is clamped below the core hole 22 and passed through the outside of one and the other of the winding portions adjacent to the core hole 22.
It is in charge of the action of transferring the core hole 22 to the vicinity of the core hole above the core hole 22, and is installed near the core holder 30 so as to be movable between the lower part and the upper part of the core holder 30. This winding guide 70 can be constructed, for example, by attaching an electromagnetically actuated scissor-shaped wire grip 76 to a rotating arm 72 driven by a motor 74 provided on the side of the core holder 30.

In addition, the winding auxiliary guide 80 grasps the wire 10 extending downward from the winding guide 70 and holds the core holder 2.
0, and is installed so as to be movable up and down between the lower part and the upper part of the core holder 20. This winding auxiliary guide 80 is, for example, attached to a lifting block 84 that engages with a feed screw 82 extending vertically at the front part of the core holder 20.
The core holder 20 can be made movable between the upper part and the lower part by being attached so as to be movable back and forth via the air cylinders 86,
This means itself is an electromagnetically actuated scissor-shaped wire grip 88.
etc. can be formed.

Further, the wire end transfer block 90 is substantially the same in structure as the wire supply block 40, and is equipped with a pair of wire feed rollers 92 that can freely approach and separate, and a wire cutter 94 installed below the rollers.
0, the wire 10 extending between the winding auxiliary guide 80 and the wire suction pipe head 60 can be moved vertically between the lower part and the upper part of the wire suction pipe head 60. The core 20 is clamped and transferred to just above the core hole 22 of the core 20, and inserted into the core hole 22 from this lower end.
The vertical movement of the wire end transfer block 90 between the lower part and the upper part of the core holder 20 engages with a feed screw 96 extending up and down, as in the case of the winding auxiliary guide 80 described above, for example. It can be mounted to the lifting block 98a via air cylinders 98b so as to be movable back and forth.

Finally, the line tension air flow generating nozzle 100 is a means for suspending the line 10, whose lower end is clamped by the line end transfer block 90, in a substantially tensioned state above the core holder 20. The core holder 20 may be configured with an air injection nozzle that forms an upward or obliquely upward air flow in the upper region of the core holder 20, or an air suction nozzle (not shown).

The core winding device according to the invention having such a configuration generally performs the winding operation on the core hole 22 portion of the core 20 in the following sequence.

First, the wire supply block 40 and the wire suction pipe head 60, each of which has the distal end of the wire 10 connected to the radiation source clamped between a pair of wire feed rollers 42, are lowered and raised until they approach the core 20 held in the core holder 30. Then, the wire feed roller 42 of the wire supply block 40 operates to transport the wire 10 through the core hole 22 of the core 20 and the wire suction pipe head 6.
0 into the wire suction pipe for a predetermined length.

Next, if necessary, the wire end clamp 50 is activated with the wire supply block 40 slightly raised.
As a result, the wire 10 extending between the wire supply block 40 and the core hole 22 of the core 20 is transferred to the core holder 30.
It is pulled out to the side and clamped. This line 1
The wire is pulled out from the wire suction pipe side (or from the wire supply block 40 side as the case may be) by the amount of lateral displacement of 0.

When the clamping by the wire end clamp 50 is completed, the wire cutter 44 at the bottom of the wire supply block 40 is operated to cut off the wire portion extending to the wire end clamp 50 from the wire supply block 40. As a result, a unit wire of a predetermined length extending from the wire end clamp 50 into the wire suction pipe is formed. This rear line supply block 40
is raised and returned to the predetermined original position, while the wire suction pipe head 60 is lowered to a state where only the lower end of the unit wire is suctioned.

Next, the winding guide 70 and the winding auxiliary guide 80
move to the lower part of the core 20 with a vertical interval and clamp the corresponding position of the unit wire (in this case, clamping by the winding auxiliary guide generally prevents the wires from sliding relative to each other). The wire end transfer block 90 moves to a position directly above the wire suction pipe head 60, and clamps the corresponding portion of the unit wire, that is, the lower end, via a pair of wire feed rollers 92 (see FIG. 2). reference).

The wire cutter 94 at the bottom of the rear wire end transfer block 90 operates to cut the corresponding portion of the wire.
Cut the connection with the line suction pipe head 60. In this case, the cut end is sucked into a wire suction pipe.

Subsequently, the wire end transfer block 90 and the winding auxiliary guide 80 rise while maintaining their vertical relationship until the wire end transfer block 90 occupies a position directly above the core 20, while at the same time, A winding guide 70 passes outside one of the winding portions of the core 20 and moves from the lower part of the core 20 to the upper part. As a result, the unit wire extends downward from the wire end clamp 50 through the core hole 22 of the core 20, and then turns from one outer side adjacent to the core hole 22, passes through the clamp part by the winding guide 70, and is wound. The wire extends upward to the clamping portion by the wire auxiliary guide 80, and then turns again to extend downward to the wire end transfer block 90 directly above the core hole 22 (see FIG. 3).

When the substantial part of the unit wire extends above the core holder 30 as described above, the core holder 3
Immediately after this, the winding guide 70 and the winding auxiliary guide 80 unclamp the unit wire, and the former returns to its original position near the core holder 30. Here, the unit wire is suspended above the core holder 30 under tension due to the air flow. Also, around the same time as above, the line suction pipe head 60 is connected to the core 20.
It rises to just below the core hole 22 of.

Next, the wire feed roller 92 of the wire end transfer block 90 rotates to feed the unit wire from its tip into the wire suction pipe through the core hole 22 of the core 20 and the wire suction pipe head 60, and to absorb the suction force by the wire suction pipe. As a result, the unit wire portion floating above the wire end transfer block 90 is absorbed into the wire suction pipe. While the formation of airflow by the rear wire tension airflow generation nozzle 100 is blocked, the wire end transfer block 90 releases the clamp on the corresponding portion of the unit wire, and the winding portion of the core 20 is substantially wrapped. At the same time, the winding auxiliary guide 80 also descends to a position above the original position, and at the same time, the wire suction pipe nozzle 60 moves lower than the original position. It descends to the upper position and becomes in a state where it attracts the lower end of the unit wire.
As a result, the unit wire is wound once around one side of the winding portion of the core 20 from the wire end clamp 50, and then extends downward.

Thereafter, the above-described operations of clamping the corresponding portions of the unit wire by the winding guide 70, the winding auxiliary guide 80, and the wire end transfer block 90 are repeated as many times as necessary to tighten one side of the winding portion of the core 20 as required. Perform several windings.

Next, the winding of the core 20 is repeated by repeating substantially the same operation as described above, except that the winding guide 70 passes through the other outside of the winding portion of the core 20 and moves from the lower part to the upper part of the core 20. Perform the required number of windings on the other side of the wire section.

Finally, the clamping of one end of the unit wire by the wire end clamp 50 is released, and each means is returned to its original position to complete the required winding.

As is clear from the above explanation, the core winding device according to the present invention allows the substantially stationary core holder and linear tension air generating nozzle to undergo substantially simple vertical and/or horizontal movement. Wire supply block, wire end clamp,
Since it is composed of a wire suction pipe head, a winding guide, a winding auxiliary guide, and a wire end transfer block, the structure is compact, and manufacturing, maintenance, and inspection costs are low, making it practical and economical.
