Abstract

(57) [Abstract] An object of the present invention is to stop the installation of a side yarn processing device for each loom and to install it on a fabric inspection machine, thereby inspecting a single piece of fabric produced from 20 to 50 loom machines. Unification by machine and processing of weft thread. SOLUTION: This edge processing device is used especially for a shuttleless loom, and this apparatus is attached to a fabric inspection machine for edge processing. This device has a cutting device using a rotary blade. The main parts of the cutting device are the rotary blade cutting machine 8 and the belt 1.
6 and a motor 17. The cutting position adjusting unit connected to the cutting device installs a fabric position detecting device under the rotary blade cutting device in order to maintain an accurate cutting position by the position detector 18, the cutting position adjusting device 20, and the controller 19. Since the cutting position adjusting device automatically operates in accordance with the change in the width and position of the fabric, the rotary blade of the side yarn processing device can always cut the side yarn having a uniform length. Further, the waste side yarns are collected by the air suction device through the air suction port into the collecting and separating device by the operation of the air suction device, and the air flows into the air suction device, leaving only the waste yarn.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the structure of the present invention will be concretely described with reference to the accompanying drawings.

FIG. 1 shows a fabric inspecting machine (also referred to as a probing machine, a reciprocating machine or an inspecting machine). FIG. 2 shows a device for processing the weft yarns arranged on both sides.
Further, FIG. 3 is an enlarged cross-sectional view showing a portion for cutting, controlling and sucking the residual yarn of FIG.

The fabric inspection machine shown in FIG. 1 is a device for transporting a long woven fabric (woven fabric cloth) in a spread state (folded in both directions) and inspecting it substantially continuously.

A conventional inspection machine of this type has an inspection (prototype) plate 10 extended by warp yarns, and a plurality of woven fabric transfer rollers arranged before and after the inspection plate 10, that is, an inspection standby fabric 11. It is composed of an upper roller 12, a lower roller 13, a guide roller 14, a winding roller 15, and the like. The latter woven fabric transfer rollers 13 and 14 include a plurality of woven fabric delivery rollers arranged side by side to separate the woven fabrics into quality grades and transport them to a predetermined position.

With such a well-known inspection machine, a plurality of woven fabrics forming one lot are fixed in order to the rear end of one woven fabric and the leading end of the other woven fabric. Roller (11,12,13,14,15) which is connected to each other by means of, and which feeds the woven fabric corresponding to the quality grade determined by the idea of the tip part to the inspection machine or the circuit, and the roller (11, 12, 13, 14, 15)
Then, the inspection is performed on the inspection machine by a device applying eyes or magnet pieces.

The weft yarn end (ear) cutting device shown in FIG. 2 comprises a rotary blade cutting machine 8, a belt 16 and a motor 17.

As shown in FIG. 4, as a method for cutting the weft yarn (weft-inserted) weaved between the warp yarns at the side portion, that is, the end portion of the woven fabric, conventionally, on a loom, rotation of scissors or the like is performed. It was common to use the ones that do not.

As for the cutting portion having the shape and operating state, the cutting device is always limited to a fixed portion, and the cutting portion having a high degree of wear is used as it is, and the durability is reduced.

When such a device that reciprocates mainly is used, the operating time of the device is set when the shuttle is hit during a proper period of operation (picking time), usually at a specific time before and after that. The twisted tube device, which requires precise setting but is difficult to adjust, has a complex defect in its construction.

In particular, in a shuttleless loom, which requires cutting the weft each time weft insertion (the weft is inserted between the warps), not only is the frequency of use increased, but local abrasion occurs more quickly. It is difficult to set an accurate operation time when driving at high speed.

According to the present invention, the above-mentioned device does not use scissors, but uses a rotary blade cutter as an outer side (side).
By forming a rotating body on, it can be used continuously for a long time,
By providing a rotary blade cutting machine for high-speed operation, the rotary blade can always cut side threads of uniform length.

In this case, the position sensor 18, the controller 19,
The cutting position adjusting device 20 is appropriately configured and operated in the weaving weft yarn side yarn processing device. In order to maintain the accurate cutting position of the side threads, a fabric position sensor is installed under the rotary blade cutting machine, and the cutting position is automatically adjusted by the adjusting device in response to changes in the width and position of the fabric. To do.

The position sensor 18 associated with this device utilizes part of the position sensor. This type of sensor has been developed from a touch switch to a position sensor. The position sensor is configured as a switch unit (not shown) that opens and closes an electric circuit and an actuator that directly mechanically contacts the detection body and transmits its position or operation to the switch unit.

Since the switch portion of the touch switch directly opens and closes the contact, the contact (position sensing point) operates continuously. This is a process for reducing the deterioration of the detection position precision due to the indirect mechanism.

Information from the sensor is transmitted to the control section by means of a display, and the cutting position adjusting device 20 and the controller 19 automatically control (set value → adjustment instrument → control side number) to accurately cut the side thread. To maintain. Control tasks often rely on digital signal processing by computers.
As a device that operates at the same time as the above-mentioned control action, there is a cut side yarn collecting device in the device shown in FIGS. 2 and 3, and the side yarn suction port 21, waste yarn separating and collecting box 22 and air are provided. It is composed of an inhaler 23. During the operation, the above-mentioned side cutting and position control are possible, and at the same time, the air suction device 2
3 works.

This is a device for facilitating the process of removing or removing the end portions of the protruding and cut wefts by suction.
Referred to as insector norle), mixed with air and removed according to a conduit 24 for removal of waste yarn separation and collection box 22.
Leads to.

In this box 22, the waste yarn (cut side yarn) and air are separated, the waste yarn remains in the collecting box, and the air moves to the air suction device 23. .

Subsequently, as shown in FIG. 3, the fabric inspection machine is equipped with a device capable of simultaneously performing the cutting action of the original cloth side portion, the collection of the side thread, and the automatic adjustment of the cutting position.

[0028]

EFFECTS OF THE INVENTION The conventional device in which the weft processing device is attached to each loom has a complicated structure, and the production cost increases due to the time required for each loom due to frequent breakdowns and parts replacement. In addition, waste of human waste caused by the operation of the weft thread processing device for collecting waste yarn from each loom and foreign substances mixed during the transportation of the waste yarn collected from the collecting cylinder attached to each loom As a result, it was difficult to reuse the waste fiber. However, the present invention has solved this point.

That is, by carrying out the weft yarn processing during the weaving of the raw silk to the inspection machine and using the weft yarn processing device attached in the fabric inspection step,
It is possible to reduce the cost of the side thread processing device installed in each conventional loom, and the side thread processing device installed in one inspection machine is compatible with 20 to 50 side thread processing devices. To do. The cost reduction effect can be obtained by the replacement of the management parts due to frequent breakdowns accompanying this and the improvement of human waste associated with the waste thread collection.
