Description

[Detailed description of the invention] This invention relates to a device for winding the thread layer wound onto a tapered tube in a non-touch type tube winding machine to an equal diameter (also called parallel winding), and its main purpose is to increase the amount of winding. The purpose is to improve weaving efficiency.

A tapered tube is generally used for the weft yarn.

FIG. 1 is a plan view showing the shape of this tapered tube.

That is, in this tapered tube 1, 2 is a body, 3 is a base cone (cone bottom), 4 is a neck, and 5 is a head.

There are some tubes in which the body 2 and the base cone 3 have the same inclination and are indistinguishable.

When the diameter of the base 2a of the body 2 is dl, and the diameter of the blue light vicinity 2b is d2, then dl)d2.

When such a tube 1 is wound with a normal build-up motion (winding device), the yarn layer 6 also becomes tapered as shown in FIG.

That is, the thread layer diameter D1 near the base 2a and the diameter D2 near the blue light 2b are DI)D2, similar to the body of the tube 1.

Therefore, as shown in Fig. 3, the inventor of the present invention increases the winding amount by forming a yarn layer 7 with a diameter E in the tapered tube 1, which contributes to streamlining the weaving operation. That is.

Figure 4 shows a pipe of equal diameter (
FIG. 2 is a perspective view of main parts related to the tube winding machine, showing an embodiment of the parallel winding device.

That is, the thread 8 is traversed in the tapered tube 1 by the traverse guide 9, and is held by the movable table 10 and advances in the direction of the blue light 2b, that is, the arrow F, by the rotation of the screw rod 11.

The screw rod 11 is rotated by a ratchet device 14 via its shaft 16, sprocket 17, chain 18, and sprocket 19.

In the ratchet device 14, a rod 13 that is moved up and down by a rotary cam 12 acts on a slide collar 20 on a swing arm 15a to reversely rotate the ratchet device 14, thereby intermittent rotation of a shaft 16 in one direction.

The point of action (slide collar 20) of the iron 13 on the swinging arm 15a is located outside the swinging arm 15a.
Since the feed amount decreases as it moves toward b, a control plate 21 that moves together with the moving table 10 is installed.
A lever 23, whose lower end is held, is passed through the elongated hole 22, and its upper portion is connected to the slide collar 20 of the swing arm 15a by a connecting rod 24.

At this time, as the moving platform 10 and the like move in the direction of arrow F, the lever 23 is gradually tilted by the oblique elongated hole 22, and the connecting rod 24 and slide collar 20 are moved toward the outer end 15b by the spring 25 fitted to the swing arm 15a. The winding diameter of the winding tube is made equal, resulting in so-called parallel winding.

Claims (1)

[Scope of utility model registration request] The traverse position of the traverse guide 9 is adjusted by the arrow F by the screw rod 11 rotated by the ratchet device 14.
In a winding device of a pipe winding machine that winds a thread 8 on a pipe 1 by moving the winding device in a direction, a control plate 21 that moves together with the movable table 10 is provided, and the control plate 21 is fitted into an inclined elongated hole 22 provided in the control plate 21. A lever 23 whose lower end is held so as to slide together is provided, and its upper part is connected to the slide collar 20 of the swing arm 15a by a connecting rod 24, so that the traverse guide 9 (movement base 10) moves in the direction of arrow F (blue The position of the point of action (slide collar) 20 of the ratchet device 14 on the swinging arm 15a changes as it moves toward the outer end 15b of the swinging arm 15a (in the direction of the light 2b).
The tube is characterized in that the amount of rotation of the ratchet device 14 is gradually reduced by moving the ratchet device 14 in the direction, and the rotation of the screw rod 11 is gradually slowed down, thereby slowing down the moving speed of the traverse position of the traverse guide 9. In contrast to the tube 1 in which the diameter d2 of the blue light 2b is gradually narrower than the diameter d1 of the base 2a of the tube (hereinafter referred to as a tapered tube), the tube winding is such that the base 2a is also wound up to the same diameter E as the blue light 2b.
