Abstract

PURPOSE:To stably hold positions of bobbins even while a turntable is being turned by a method wherein rotatable winding shafts are provided at two oppo site faces of the turntable and pressure shafts which energize the bobbins to be supplied to the winding shafts in an axial direction of the winding shafts from the outside are installed at positions adjacent to the winding shafts. CONSTITUTION:Pressure shafts 6e, 6b are held in positions adjacent to winding shafts 2e, 2b of a turntable 3 via brackets 7a, 7b; bobbins 1a, 1b are energized by a force of springs 8a, 8b. When a cylinder 12 is driven, a U-shaped groove 9a of an opening and shutting lever 9 is pressed into the pressure shaft 6b. Then, the lever 9 is turned by driving a cylinder 11; the pressure shaft 6b is expanded; the bobbin which has been wound is taken out; the bobbin 1b which has not yet been wound is supplied to the winding shaft 2b. In addition, the lever 9 is returned by driving the cylinder 11; the bobbin 1b is energized to the winding shaft 2b by means of the pressure shaft 6b. Since the pressure shafts 6a, 6b are attached to the turntable 3 by using the brackets 7a, 7b in this manner, the bobbins 1a, 1b can be held stably at the winding shafts 2a, 2b not only during a winding operation but also while the turntable is being indexed and turned.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a pobbin rotary winding device. It is.

Conventional technology Various winding devices have been proposed in the past.

A conventional winding device will be explained below. FIG. 3 is a side view of a conventional winding device. 14a and 14b are bobbins, 16 & 16b are winding shafts, and springs 22 hold the bobbins 142L and 14b, respectively. 16 is a turntable, and in this example, there are winding shafts 1 on two opposing sides.
6&.1sb is attached and performs intermittent rotation every 180 degrees. 17 is a guide nozzle, which has three nozzles: top and bottom, left and right, and front and back.
The wire rod 18 passing through the guide nozzle 17 can be freely positioned in each direction by a pulse motor and guided to an arbitrary position. The housing 19 is a push shaft, and the cylinder 2
0, the block 21 moves to the winding shaft side, and the push shaft 19 is pressed against the pobbin 14 by the force of the spring 22. 23 is a slide shaft.

The operation of the winding device configured as described above will be described below.

As shown in FIG. 3, the bobbin 14 is attached to the winding shaft 151L on the opposite side from the guide nozzle 17! Attach L.

Next, rotate the turn tape I 16 180 degrees, and press the push shaft 1.
At step 9, press the pobbin 14b toward the winding shaft 15b. Although not shown in the figure, external rotational force is applied to the winding shaft 15b on the guide nozzle 17 side via a clutch. Next, the wire 18 guided to an arbitrary position by the guide nozzle 17 is wound around the winding terminal 24 on the pobbin 14b by moving the guide nozzle 17. Next, the wire is wound onto the winding groove 26 on the bobbin 14b.
This is done by moving the /1 gear above the winding groove 26 and rotating the winding shaft 15b. At this time, the bobbin 14b receives tension from the wire rod 18 in one direction and rotates at high speed.
In order to stabilize the position of b, use the push shaft 19 to
It is necessary to press the winding shaft 1sb against the winding shaft 1sb. Finally, winding is performed at the end of winding by moving the guide nozzle 1717 around the winding terminal 24 in the same manner as at the beginning of winding, and this completes the winding of a single wire.

In addition, while winding is being carried out on the guide nozzle 1A side, a turn tape/l/16
It has winding shafts 1st and 15b on both sides.

Problems to be Solved by the Invention However, in the above conventional configuration, the turn tape A/1
During the rotation of 6, Pobin 14! L, 14b is the winding shaft 1sa, 1
Since it is held only by sb, the winding shaft 1sa, 1esb
When using a bobbin that is difficult to hold with a chisel or a bobbin that is long in the axial direction of the winding shaft, there is a problem in that the position of the turn tape/l/16 shifts during rotation.

The present invention has been made to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a winding device that can stably maintain the position of a bobbin even while a turntable is rotating.

Means for Solving the Problem In order to solve this problem, the winding device of the present invention has a rotatable winding shaft on at least two opposing sides of a rotatable turntable, and a winding shaft facing the winding shaft. , the axial direction of the winding shaft,
The turntable has a guide nozzle movable in the horizontal direction perpendicular to the winding shaft and the vertical direction perpendicular to the winding shaft to guide the wire, and further includes a bobbin to be supplied to the winding shaft at a position close to each of the winding shafts of the turntable. The winding shaft has a push shaft that urges the winding shaft from the outside in the axial direction of the winding shaft, and further engages with the push shaft at a position where the bobbin of the turntable is supplied, and the push shaft is pressed against the turntable. It consists of an opening/closing lever that can be pushed outward.

By the configuration with the action, it is possible to improve the stability of the position of the bobbin even during index rotation of the turntable.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to one drawing. FIG. 1 is a side view of a winding device in one embodiment of the present invention. 1a and 1b are bobbins, 21L and 2b are winding shafts, 3 is a turntable, 4 is a guide nozzle, 6 is a wire rod, ea and eb are push shafts, turn tape/I/

, 1blC are biased by the forces of springs sa and ab. Furthermore, as an opening/closing part of the push shaft OIL 6b, 9 is an opening/closing lever which is rotated by a cylinder 11 with a shaft 10 as a fulcrum to push and spread the push shaft 6b. Further, FIG. 2 is a front view of the opening/closing portion of the push shaft 6b, and the opening/closing lever 9 slides in the left-right direction due to the drive of the cylinder 12. 13 is a slide shaft.

The operation of the winding device of this embodiment configured as described above will be described below. As shown in FIG. 2, the U-shaped groove 9a of the opening/closing lever 9 is inserted into the push shaft 6b in order to drive the cylinder 12. Next, as shown in Figure 1, cylinder 1
1 rotates the opening/closing lever 9, pushes and spreads the push shaft 6b, takes out the winding liquid bobbin, and supplies the unwound bobbin 1b to the winding shaft 2b. Next, the opening/closing lever 9 is returned by driving the cylinder 11, and the push shaft 6b moves the pobbin 1b to the winding shaft 2.
