Description

Fabric feeder of smoke bomber

This design is installed in the upper part of the smoke bomber, and the feeder pulls up the front end of the fabric and puts it on the driving roller for lowering the fabric. It relates to a fabric feeding device of the soft bomber to be able to supply the front end of the rod to the bar very stably.

As is well known in the prior art, when connecting the fabric and the fabric is connected by sewing the front end of the fabric to be fed later to the end of the first fabric entered into the sewing, which was followed by the following closure.

In other words, in order to connect the new fabric to the end of the fabric already supplied by the soft fighter, the end of the new fabric is usually very cumbersome and time-consuming because two workers face each other after the fabric has been supplied. It was excessively demanded, resulting in a rise in cost and reliability of fabrics.

Therefore, the present invention has been devised in view of the above-mentioned conventional problems, and in particular, the upper part of the soft bomber is operated by the driving roller for lowering the fabric and the air cylinder in an inclined direction to press the fabric to prevent the falling of the fabric and It is composed of driven roller for lowering fabric which pushes the fabric to the sewing part while advancing and reversing. The main surface, to provide the fabric supply device that can automatically supply the fabric by supplying the front end of the fabric to the sewing section by the organic roller acts organically acts as the fall prevention roller and the descending roller for fabric lowering purpose. Is there.

Hang the sealed fabric on the hanger rod (2), and the front end of the fabric is hanged on the transfer table (4) which slides up and down on the guide rod (3), the transfer table (4) is bitten up with the front end of the fabric In the soft boom (1) configured to drop on the driving roller (5) for the fabric lowering;

The inclined direction transfer frame (8) is installed at the rear of the driving roller (5) for the fabric lowering forward and backward by the air cylinder (6) and the guide rods (7) (7 '). 8) fixedly install roller support sections (9) and (9 ') at both end portions of the support sections (9) and 9' (9 ') ends to install a flow prevention roller (10) at the end of the fabric;

The fabric lowering driving roller 5 is installed in front of the lowering driven roller 11 to move forward and backward, and the lowering driven roller 5 for lowering the fabric is an air cylinder 12 and a rack gear 13. ) And the guide rods 14 and 14 'to the slider 15 for conveying, so that when the air cylinder 12 operates, the driven roller 11 for lowering the fabric is also moved forward and backward, and the slider 15 The pinion 16 is built into the rack gear 13 to stably drive the rack gear 13 so that the driven roller 11 for the fabric lowering is very stably moved forward and backward.

Not explained;

21 is the chain 22 is the connecting guide

The present invention configured as described above is a slide type to move up and down the transfer guide (4) to take up the front end of the fabric to pull the top of the fabric lowering driving roller (5) to release the fabric pulled quickly By operating the air cylinder (6) to close the fall prevention roller 10 of the fabric to the back of the driving roller for the fabric lowering (5) to prevent the case that the supplied fabric slips down to the original state, Subsequently, when the air cylinder 12 operates to advance the driven roller 11 for lowering the fabric and slides it to the driving roller 5 for lowering the fabric, the fall prevention roller 10 of the fabric is raised and returned to its original position. As the transfer table 4 descends, the driving roller 5 for lowering the fabric is forced to pull the fabric to the bar position.

The timing according to the action of the transfer table 4, the driving roller for the lowering fabric 5 and the fall prevention roller 10 and the lowering driven roller for the lowering fabric can be controlled as a limit switch or a sensor. Since this configuration is possible by known technical means, detailed description and illustration are omitted.

On the other hand to describe in more detail the action of the fall prevention roller 10 and the fabric lowering driven roller 11 of the fabric of the present invention;

In the case of the anti-flow roller 10, the slide-type feeder 4 is completely raised with the fabric, and when the fabric is released while reaching the end of the guide groove 3, the fabric itself is stretched longer than the top. Because it is in the state of trying to flow naturally, the air cylinder (6) is operated to pull down the inclined direction transfer frame (8) in the flow prevention roller 11, the flow of the fabric flows down naturally The prevention roller 11 is in close contact with the driving roller 5 for the fabric lowering to prevent the flow of the fabric.

Subsequently, the air cylinder 12 is also operated to advance the slider 15, so that the driven lowering roller 11 placed at the end of the slider 15 comes into close contact with the driving roller 5 for lowering the fabric. Falling prevention roller 10 of the fabric is returned to the original by the air cylinder (6) while the conveying table (4) that pulled up the fabric is also lowered by the guide groove (3), driving roller for fabric lowering (5) ) And the descending follower roller 11 for the fabric continue to operate until the fabric is completely released even after the fabric extends the fabric, and then the driven roller 11 for the fabric lowering is also returned to its original position by the air cylinder 12. It will return.

As described above, the present invention is organically transported by installing the anti-flow roller 10 and the driven roller 11 for lowering the fabric, respectively, on both sides of the lowering driving roller 5 installed at the upper end of the soft bomber. It is a very useful design that can make the supply of fabric automatically by constructing material, thereby reducing manpower, time, and productivity, and maximizing reliability by contributing to automation of the bomber. .
