Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beam shaft attaching / detaching device which is suitable for beam exchange of a tricot machine or a Russell machine, and also to a beam aligning device and a shaft inserting / pulling device used therefor. is there.

[0002]

2. Description of the Related Art A beam mounted on a tricot machine or a Russell machine is a large beam having a diameter of a beam flange of about 50 to 75 cm, and a total weight of a warp wound state is about 200 to 350 kg. . In order to mount such a beam on a knitting machine, a plurality of beams, for example, 5 or 6 beams, are aligned by aligning the cores of the shaft insertion holes, and the beam shaft is inserted into the communicating shaft insertion hole. The both ends of the beam shaft were supported by the knitting machine.

The conventional method of exchanging the beam is to remove the beam shaft from the knitting machine after the warp release of the beam is completed, install an empty beam on the support, and pull out the beam shaft while manually holding it. After that, the thread-wound beam in which the warp is wound is aligned by aligning the cores of the shaft insertion holes, and while holding the beam shaft by hand, push one end into the shaft insertion hole, and then insert the beam shaft sequentially. It was a thing.

[0004]

However, since the beam shaft is a heavy object having a weight of about 40 kg to 50 kg, such a manual attaching and detaching work of the beam shaft is
The work was hard work. In particular, when the beam shaft was inserted, the weight of the wound beam was large and the friction area was large, so that the beam could not be smoothly inserted.

Therefore, the beam shaft was forcibly inserted while being hit, but as a result, the beam flange was rubbed by the support and moved, which sometimes damaged the beam flange. When the beam flange is damaged, the warp thread rubs against the damaged portion of the beam flange when the warp thread is released, causing fluff and thread breakage, which causes serious problems.

An object of the present invention is to provide a beam shaft attaching / detaching device which saves the beam replacing work without damaging the beam flange and solves the above problems, and is suitable for use in the attaching / detaching device. The present invention aims to provide a beam aligning device and a shaft inserting / pulling device.

[0007]

In order to solve the above problems, the present invention employs the following means. That is, the beam shaft attaching / detaching device 1 according to the present invention includes a beam aligning device 5 for aligning a plurality of beams in a state where the cores of the shaft insertion holes 3 are aligned, and a beam alignment device 5 for connecting the beams to the shaft insertion holes. A shaft insertion / extraction device 7 for inserting the shaft 6 or for extracting the beam shaft in the inserted state is provided.

The beam aligning device 5 is provided with a pair of linear supporting portions 10, 10 for supporting the beam flange 9 from below in parallel with a required space.

Further, the shaft inserting / pulling-out device 7 is a chucking device 22 for chucking an end portion of a beam shaft to a traveling body 21 which reciprocates along a rail 20 which is continuously provided in a lengthwise direction of a linear supporting portion. Is installed so that it can move up and down,
The chuck device 22 is configured so as to be rotated by the rotating device 23 about the axis of the chucked beam shaft (oscillating rotary motion or rotary motion in one direction), and a shaft for supporting the chucked beam shaft from below. The lifter 25 is provided so as to be able to move up and down, and the shaft lifter 25 is set in a lowered state that does not hinder the traveling operation of the traveling body 21.

Moreover, the shaft lifter 25 and the chuck device 22 are in a raised state such that the axis of the beam shaft, one end of which is chucked by the chuck device and the lower end of which is supported by the shaft lifter, is aligned with the center of the beam shaft insertion hole. It is characterized by having taken.

Further, the beam alignment device 5 according to the present invention comprises a pair of linear support parts 1 for supporting the beam flange 9 from below.
0 and 10 are provided in parallel at a required interval, and a beam lifter 12 is provided between the linear support portions 10 and 10.
Is provided so that it can be moved up and down, and the upper surface 15 of the beam lifter is positioned on the lower side of the upper ends of the linear supporting portions 10, 10 in its highest lifted state. It is characterized in that it is adapted to be supported by the strip-shaped support portions 10, 10.

A shaft inserting / pulling device 7 according to the present invention.
Is provided with a chuck device 22 for chucking an end portion of a beam shaft on a traveling body 21 that reciprocates along a rail 20 so as to be movable up and down. A shaft lifter 25, which does not rotate about the axis and supports the beam shaft in a chuck state from below, is provided so as to be able to move up and down.

[0013]

However, in order to extract the beam shaft from the empty beam, each empty beam is supported by the linear supporting portions 10 of the beam aligning device while the plurality of empty beams are mounted on the beam shaft ( 2 and 4). After that, the traveling body 21 is advanced toward the beam at the end, and the projecting end portion 51 of the beam shaft is chucked by the chuck device 22 (FIG. 12).

After that, when the rotating device 23 gives the chucked beam shaft a rotational motion (oscillating rotational motion or one-directional rotational motion) about the axis of the chucked beam shaft, the traveling body 21 is retracted. Is smoothly pulled out (Fig. 3). Before the other end of the beam shaft comes off the end of the shaft insertion hole, the shaft lifter 25
And the beam shaft 6 is supported from below (FIG. 3). By further moving the traveling body 21 backward,
The other end of the beam shaft comes out of the shaft insertion hole (Fig. 3).

On the contrary, when inserting the beam shaft into the take-up beam, a plurality of the take-up beams are attached to the linear support portion 1.
They are supported by 0 and 10 and arranged (FIGS. 2 and 4). As a result, the respective winding beams are naturally aligned in a state where the shaft insertion holes 3 have the same center.

After that, the beam shaft is inserted into the shaft insertion hole through which each beam communicates. One end portion of the beam shaft is chucked by the chuck device 22 and the intermediate portion is supported by the shaft lifter 25 from below. Then, the axis of the beam shaft and the center of the shaft insertion hole are made to coincide with each other by the upward and downward movements of the shaft lifter 25 and the chuck device 22 which are interlocked with each other (FIG. 3).

After that, when the rotating unit 23 advances the traveling body 21 while giving the chucked beam shaft a rotary motion (oscillating rotary motion or one-directional rotary motion) about its axis, the beam shaft 6 is moved to the shaft. It is smoothly inserted into the insertion hole.

At a suitable time when the other end of the beam shaft is inserted, the shaft lifter 25 is lowered so as not to hinder the traveling of the traveling body 21. After the beam shaft is inserted as required, the chuck state by the chuck device 22 is released (see the release state shown by the one-dot chain line in FIG. 12).

When the beam aligning device 5 is provided with the beam lifter 12, the work of supporting the take-up beam on the linear support portion and removing the empty beam from the linear support portion can be performed reasonably and easily. You can

That is, since the upper surface 15 of the beam lifter 12 is located at the lowermost side of the upper end 16 of the linear support portion when the beam lifter 12 is at the highest position, the take-up beam is rolled when the beam shaft is inserted. It can be arranged between the linear supporting portions 10 and 10 without difficulty.

Further, when the beam lifter is at the highest position,
Since the upper surface 15 is located on the lower side of the upper end 16 of the linear support portions, the beam flanges 9 and the linear support portions 10 and 10 are respectively arranged in the beams once arranged between the linear support portions even if they try to roll. The engaged state (the state of the beam flange shown by the chain double-dashed line in FIG. 4) does not come off from between the linear support portions 10, 10.

After that, when the beam lifter 12 is lowered, the beam is naturally supported by the linear supporting portions 10, 10.

On the contrary, when removing the empty beam extracted from the beam shaft, when the beam lifter 12 is set to the highest position, the upper surface 15 of the beam lifter is substantially flush with the upper ends of the linear supporting portions 10, 10. Therefore, it is possible to easily remove the empty beam by rolling it.
