Description

Description: BACKGROUND OF THE INVENTION (Field of Industrial Application) The present invention relates to a winding machine, and more particularly, to a means for engaging a lead regulating claw provided on a fryer with a lead on which a work is inserted. .

(Prior Art) A winding machine for manufacturing a choke coil or the like by winding a wire around a work is provided with a lead regulating claw 103 on a fryer 102 where a wire 101 is adjusted, as shown in FIG. The setting claw 103 is attached to the chuck provided on the rotating drum 104.
The flyer 102 is rotated around the lead 106 while engaging the lead 106 held by the cantilever 105 to prevent bending and deflection of the lead 106, and a wire 107 is attached to the work 107 inserted into the lead 106. 101 is to be wound.

The winding machine is provided with a plurality of the chucks 105 in parallel so that the wire 101 can be wound around a large number of works 107 at the same time.
The same number is also juxtaposed.

The rotating drum 104 rotates the index in the direction of the arrow N1 to position the work 107 at the position wound by the fryer 102.
The index rotation is performed again to send 107 to the next process.
When the rotating drum 104 performs index rotation in this way,
When the lead setting claw 103 is engaged with the lead 106, the lead
The lead regulation claw 103 is a drum
When the index 104 rotates, it must be detached from the lead 106. For this reason, conventionally, a presser 108 is provided near the rear end of the lead train claw 103, and the presser 108 is reciprocated by a cylinder (not shown) to press this rear end, thereby causing the lead train claw 103 to move. By rotating horizontally in the direction of arrow N2, the lead 106 was detached.

(Problems to be solved by the invention) In order to increase the work efficiency, the winding machine is
It is necessary to arrange as many as possible 2 as many as possible so that the wire 101 can be wound around a larger number of works 107 at the same time.
For this purpose, the width D of the fryer 102 must be reduced to make it as small and compact as possible. However, in the above-described conventional means, the pressers 108 that reciprocate in the width direction have to be individually arranged on the side of the rear end of each fryer 102.
The width D per piece is considerably large, so that it is difficult to arrange a large number of fryers 102 side by side in a limited width, and there is a problem that work efficiency is not improved.

Therefore, an object of the present invention is to provide a means for reducing the width of a fryer so that a larger number of fryers can be arranged in parallel.

(Means for Solving the Problems) For this purpose, the present invention provides a lead adjusting claw that releasably engages with a lead that is cantilevered and held by a chuck arranged side by side on the body surface of a rotary drum, and a wire adjusting mechanism. A plurality of fryers each having a banded nozzle are arranged side by side on a block arranged in parallel with the rotary drum so as to be rotatable about a rotation axis. In the winding machine in which the wire is wound around the work inserted into the lead by rotating the block, the block is slidably disposed by driving of a driving device, and the block is reciprocated. By moving, the lead regulating claw is disengaged from the lead.

(Operation) According to the above configuration, the presser is not required, the width of the fryer is reduced, and the block in which a number of fryers are juxtaposed is slid reciprocally, so that the lead regulating claw is attached to the lead. Can be disengaged.

Example Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a winding machine, wherein 1 is a horizontally long rotating drum, and a plurality of collet chucks 2 are juxtaposed on a body surface thereof. Reference numeral 3 denotes a horizontally long block, which is arranged in parallel with the rotary drum 1, and a number of fryers 4 are arranged side by side on a surface facing the rotary drum 1. This block 3 is arranged on a table 5. A guide rail 6 is provided on the table 5 along its length direction, and a slider 7 fitted to the guide rail 6 is inserted on the bottom surface of the block 3. Reference numeral 8 denotes a cylinder as a driving device disposed on the side of the block 3, and its rod 9 is connected to a side surface of the block 3. Therefore, when the cylinder 8 is operated and the rod 9 protrudes and retracts, the block 3 reciprocates in the lateral direction N1 along the guide rail 6.

The table 5 is provided with a guide rail via a slider 11.
12 is slidably mounted. A nut 5a is formed at the center of the table 5, and a feed spring 13 is screwed to the nut 5a. Reference numeral 14 denotes a drive motor for driving the feed screw 13. Therefore, when the motor 14 is driven, the table 5 reciprocates in the front-rear direction N2. Reference numeral 15 denotes a spline shaft inserted on both sides of the table 5, which is driven via a motor 16 and a timing belt 17.
To rotate.

FIG. 2 shows a detailed structure of the fryer 4. The fryer 4 includes a rotating shaft 21 mounted on the block 3 side and a clamp member 22 mounted on the tip of the rotating shaft 21. A holder 23 mounted on the clamp member 22 and extending toward the rotary drum 1; a nozzle 24 and a grooved roller 25 mounted on the tip of the holder 23; and mounted along the inside of the holder 23. Made of a lead-reducing claw 26. Therefore, the flyer 4 is rotatable about the rotation shaft 21. 27 is a wire, nozzle 24 and roller
It is tuned to 25. 28 is a timing pulley,
It is connected to the spline shaft 15 via a transmission means such as a timing belt (not shown), and transmits the rotation of the motor 16 to the fryer 4 to rotate the fryer 4 about the rotation shaft 21.

Reference numeral 30 denotes a lead whose one end is held by the chuck 2, and a work 31 is inserted into the center of the lead. When the wire 27 is wound around the work 31, the lead 30 is bent or displaced by engaging the engagement portion 26 a at the tip of the lead regulation claw 26 with the free end of the lead 30. To prevent

This winding machine has the above configuration, and the operation will be described next.

With the rod 9 of the cylinder 8 retracted and the block 3 slid rightward (see the dashed line in FIG. 1), each fryer 4 also retracts to the right (see the dashed line in FIG. 2). In this state,
The rotating drum 1 rotates in the index direction in the N3 direction, and positions each lead 30 held by the chuck 2 at a position facing each flyer 4. Next, the block 3 slides to the left, and the engaging portion 26 a of the lead regulating claw 26 engages with the lead 30. Next, when the motor 16 is driven, the flyer 4 rotates around the lead 30 by rotating about the rotation shaft 21, and the wire 27 is wound around the work 31. At that time, the motor
The drive 14 drives the block 3 to move in the N2 direction, thereby moving the fryer 4 in the length direction of the lead 30 and winding the wire 27 from the lead 30 to the work 31. When the winding is completed, the rod 9 of the cylinder 8 retreats, the block 3 slides rightward, and the engaging portion 26a of the lead regulating claw 26 is separated from the lead 30. Then, the rotating drum 1 returns to the arrow N3.
The index rotation in the direction is performed, the next row of leads 30 is positioned at a position facing the fryer 4, and the above operation is repeated. As described above, in the present apparatus, a large number of fryers 4 are juxtaposed on the block 3 and the block 3 is reciprocated in the lateral direction N1 so that the lead regulating claw 26 of each fryer 4 is engaged with the lead 30. Can be removed.

(Effects of the Invention) As described above, according to the present invention, the width of the fryer can be reduced by eliminating the need for the presser of the conventional means.
Therefore, within a limited lateral dimension, a larger number of fryers can be arranged side by side, and a wire can be wound around many works at the same time.
