JPS6123060A - Cloth cutting processing apparatus in automatic exchange of cloth winding roller - Google Patents

Abstract

PURPOSE:To permit the automatic winding of the cut edge of cloth by installing a cutter means so as to approach onto the peripheral surface of a vacant roller and allowing the fluid supplied from a nozzle installed in front of the cutter edge to jet-out so that the edge of the cut cloth is wound onto the peripheral surface of the vacant roller. CONSTITUTION:A cloth taking-up roller 1 installed onto a weaving machine T is transferred onto a flat car 2 by an exchanging arm 6, and a vacant roller 8 on the flat car 2 is transferred and installed onto the weaving machine T side, taking-up the cloth W. The cutter means 10 at the top edge of a supporting arm 11 is set close to the vacant roller 8 and pressed so as to lift-up the cloth W from below, and the cloth W tension-applied between a guide 10 and a slide bar 12 is cut in the direction of width by a cutter edge 10a by the shift of a runner 13 along the slide bar 12. At the same time, fluid, e.g., air or water is jetted towards the peripheral surface of the vacant roller 8 from a nozzle 14, and the edge W2 of the cut cloth is wound so as to attach onto the peripheral surface of the vacant roller 8.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cloth cutting device for automatic cloth roll exchange.

Currently, when replacing the cloth rolls on one machine, when the rolls are filled with woven cloth, the loom is stopped and the worker cuts the cloth in the l] direction with a cutter.

A method is adopted in which the rolled cloth roll is removed from the loom, a new empty roll is attached to the loom, the end of the cloth is wound around this, and the loom is restarted. Needless to say, such roll replacement work requires time away from home, and particularly in high-speed looms, the drop in productivity caused by the stoppage of operation is significant. For this reason, there have been requests to automatically change rolls by applying recent Roboso technology. It was not the most difficult thing to do.

Therefore, in order to meet the above requirements, the inventors of the present invention developed the first
They made proposals as shown in Figures 9 to 9. The contents of the proposal are as follows.

■ Roll changing arms 6 are installed on the trolley 2 that is guided to a position facing the loom T.

(2) The exchange arms 6 are operated based on a predetermined exchange signal to transfer the cloth roll 1 that is currently winding the cloth onto the cart 2 located in front (see FIGS. 1 to 3).

■ While the fabric roll 1 on the trolley is being used to wind up the cloth to be woven on the loom side, the empty roll 8 loaded on the trolley 2 is transferred to the loom side using the roll changing arms 6, 6, and the cloth to be woven is wound up on the loom side. Figures 4 to 6.
(see figure).

■ Next, in the vicinity of the empty roll 8 mounted on the loom side, the cloth that is being taken up twice from the loom side to the cloth winding roll on the trolley side is cut in the cloth direction, and the cut cloth end W2 on the empty roll side is cut into the cloth. By winding the cloth around the outer periphery of the roll to start the winding, and at the same time, winding the cut cloth end W1 on the other cart side to the cloth wrapping roll 1 on the cart (see FIGS. 7 to 9).

This allows cloth rolls to be replaced automatically without stopping the loom. Note that 3 in Figure 2 is a press roll,
4 is a cloth-wrapped press roll, 5 is a stopper, and 9 is a roll rest.

In the present invention, a fabric roll 1 attached to a loom T is transferred to a trolley 2 disposed in front of the loom T without separating it from the cloth being woven, and while the cloth winding continues, the fabric roll 1 is loaded onto a seven carriage 2. After the empty roll 8 is transferred to the loom T and installed, the fabric from the loom T to the fabric roll l on the trolley 2 is cut near the empty roll, and the end of the fabric on the loom side is wound around the empty roll 8 and wound again. The purpose is to provide a cloth cutting mechanism necessary for carrying out the cutting.

- Therefore, in such a cloth cutting processing mechanism, the following functions are required.

Ca+ Move the cutter 10a in the direction of the cloth while tensioning the cloth near the empty roll.

(b) Spray the cut cloth edge W2 so as to adhere it around the empty roll.

To discuss this point in more detail, the two
A cutter means 10 is attached to the tip of the joint support arm 11. As shown in FIG. 10, this cutter means 10 has a slide cutter 1 attached to a slide bar 12 extending inwardly of the cloth.
0a is slidably attached via a runner 13, and as shown in Fig. 1, the belt 16 attached to the boots IJ15, 15... is moved forward and backward in a reciprocating direction by rotating the drive pulley 17 forward and backward. It is meant to be given.

In addition, as shown in FIG. 11, the runner I3 has
A nozzle 14 is arranged so as to be directed near a portion of the empty roll 8 that faces the cutter, and moves in the direction of the cloth together with the cutter 10a. Note that the moving direction of these slide cutter 10a and nozzle 14 is 9.
In the illustrated example, the rotation of the motor M is controlled by the protrusion 13a of the runner, the switch SW, or the pot.

It is controlled by the relationship between

Therefore, as shown in FIGS. 8 and 11,
Cloth roll 1 from below the empty roll 8 mounted on the loom T
When the cloth W connected to the cutter 10b is slightly lifted, tension is applied to the cloth between the slide bar 12 and the guide 10b, so that when the slide cutter 10a moves, the cloth W is cut smoothly and linearly. Now, when the nozzle 14 moves together with the slide cutter 10a and a fluid (for example, air or water) is injected toward the circumferential surface of the empty roll 8, the cut cloth edge W2 is attached to the circumferential surface of the empty roll at the same time as cutting. It will wrap around as it does.

Incidentally, other examples of the cloth cutting mechanism described above include:
What is shown in FIG. 12 is proposed. In this case, a motor M is provided on a runner 13 which is slidably attached to a slide bar 12 extending in the direction of the fabric, and the drive of this motor is transmitted to a drive shaft 19 via transmission gears 18, 18" and 18". , a pinion 21 fixed to this drive shaft 19
is engaged with the rack 20 on the lower surface of the slide bar 12, so the runner 13 moves along the slide bar 12. On the other hand, bevel gears 22, 22 are disposed at the tip of the drive shaft 19.
The slide cutter 10a is rotated through the slide cutter 10a, and the cloth is cut by the rotation of the slide cutter 10a.

Further, as shown in FIGS. 13 and 14, the slide bar 12 is simply used as a tension applying means, the timing belt 24 is tensioned by pulleys 25 in parallel with the slide bar 12, and the holder 23 holding the slide cutter 10a is attached. Of course, it is also possible to move it in the direction of the cloth using the timing belt 24. Note that the moving direction is also controlled by controlling the rotating direction of the motor M by contacting and separating the contact piece 26 between the switch SW and SW2.

As explained above, according to the present invention, the cloth W being continuously wound from the loom T onto the cloth roll 1 on the trolley 2 is cut and wound again onto a new empty roll 8 newly installed on the loom T. To make it easier to start removing the cloth, it can be cut in the direction of the cloth near the empty roll and sprayed so as to adhere to the circumferential surface of the empty roll.

Therefore, a cloth cutting mechanism suitable for automatically replacing the cloth rolls without stopping the loom is provided.

Note that the present invention has been described based on specific examples.

The present invention is not limited to these specific examples and can be modified in nine different ways. For example, although a blade cutter was used as the slide cutter 10a, a heat cutter may be used instead.

Various cloth cutting cutters may be used, such as a razor cutter, a hydraulic cutter, etc., and the nozzle 14 is connected to the cutter 10.
Although the nozzles 14 are moved in the direction of the cloth along with a, the nozzles 14 may be arranged in parallel or may be slit-type nozzles so that the cloth cut end W2 can be sprayed toward the empty roll side over the entire direction of the cloth.
