And since it can be applied even when the fiber fabric is input to centuries or tenter, there is also an effect that can simplify and simplify the fiber processing process.

Description

Twist-releasing system of fiber fabric using a number of parallel linear lights {A SYSTEM THAT UNTWISTS FABRIC WITH PARALLEL STRAIGHT LINES OF LIGHT}

The present invention relates to a system for releasing twist of a fiber fabric using a plurality of parallel linear lights, and more particularly, if the fiber fabric is twisted in a fiber processing process, the quality of the fiber fabric is degraded or it is impossible to proceed to the next process. Therefore, the twisting of the fiber fabric must be released. At this time, to release the twisting of the fiber fabric, first, the left and right directions and the degree of the twisting of the fiber fabric must be known. Is unsatisfactory, which lowers the reliability of Scotch itself and hears complaints from users. Therefore, by constructing an electronic sensing device that can detect 100% twisted state of fiber fabric using parallel straight light, it improves the reliability of Scotcher and provides convenient use of Scotcher. Furthermore, the present invention is a dehydrator or dyeing machine. The present invention relates to a system for untwisting a fiber fabric using a plurality of parallel linear lights that can simplify the fiber processing process by making the scorch unnecessary in the fiber processing process by attaching to other fiber processing machines.

In general, in order to release the twist of the fiber fabric, first, the left and right directions and the degree of twisting of the fiber fabric must be known. However, the accuracy of the mechanical sensing device used in the conventional scotcher is not satisfactory. It is the current situation to drop and hear complaints from users.

Therefore, the fiber fabric is necessarily twisted in the water after a process such as washing the fabric for centuries or dyeing in a dyeing machine.

At this time, if the twisted fiber fabric is left as it is, the next process is impossible, so the fiber fabric should be sent to the next process after releasing the twist to immediately place the fiber fabric.

In this situation, a series of processes for releasing the twisted fiber fabric is called scotching, and a mechanism having such a function is generally called a scutcher.

Conventional Scotchers used for this purpose use a so-called washboard type sensing device having a grooved iron plate on both sides or a cogwheel-type sensing device as a sensing device for detecting twisting of a fiber fabric. However, due to the inferior accuracy of these mechanical sensing devices, the reliability of the machine itself is deteriorated.

In addition, these mechanical sensors do not directly detect the twisted state of the fabric, but use the natural restoring force that shows when the twisted fabric descends from high to low. Since the devices indirectly find out by using the force to rotate, there is a disadvantage that a structure for hanging the fiber fabric 10 m or more in the air is necessary. In addition, these mechanical sensors tend to erect mechanical structures as high as possible in the construction of the scavenger, because the higher the structure that suspends the fabric, the better the performance. However, in this case, the thin fabrics that absorbed a lot of water have defects such as damage to the tissues of the fabric due to the weight of the water while going up in the air.

In addition, the mechanical detection device as described above is less accurate to detect the twisting phenomenon of the fiber fabric when the chemical material, such as chemical fiber or the water is wet, so that the fiber phenomenon is not 100% perfectly detect the ska During the operation, the fiber fabric tends to lean to one side of the machine, causing the machine to stop working frequently.

As such, since the machine is not perfect due to the imperfection of the detection device, the conventional scorch has a problem that the operator always needs to look at the machine even after the machine is installed, as well as a 24 hour manager.

In addition, due to the frequent failure of the mechanical sensor has a disadvantage in that the cost required for the maintenance and management of the machine additionally generates a lot of economically.

The present invention has been made in order to solve the various problems as described above, by using the twist release system of the fiber fabric using a parallel linear light to detect the twisting phenomenon of the fiber fabric 100% accurately to automatically detect the twisted fiber fabric It aims to improve the efficiency of work by quickly solving the problem.

In order to achieve the above object, a video camera has a curved stripe pattern that is formed in a fiber unit by parallel linear light projected from a plurality of line laser beam generators or light source lamps and a slit shielding plate to a fiber fabric in the twist recognition unit of the fiber fabric. When converted into an electrical signal, the computer control unit measures and analyzes the result in real time, and transmits the result to a drive motor connected to a rotating disc with a fiber fabric tightening roller, and according to the twisted left and right directions of the fiber fabric and the degree thereof. The present invention relates to a system for releasing twist of a fiber fabric using parallel linear light, which is configured to automatically unwind the fiber when twisting the rotating disk.

Shaving, and FIG. 8 is a new twist fiber fabric decompressor by installing a plurality of a main portion of the present invention: a side view configured to (non-ska hit Scutcher Vision).

First, in the configuration of the present invention, a plurality of parallel linear lights 26 generated by a plurality of parallel linear light generators 27 formed at predetermined positions inside the twist recognition unit 16 of the fiber fabric are twisted of the fiber fabric. The curved stripe pattern projected onto the twisted surface of the fiber fabric passing through the recognition unit 16, wherein a plurality of parallel linear lights 26 are formed on the twisted fiber unit unit is used to display the image of the image camera 14. After being recognized as an electrical signal and transmitted to the computer control unit 17 in real time, the computer control unit analyzes the curved stripe patterns of the plurality of parallel linear lights 26 to determine the twist direction and degree of the fiber fabric. Afterwards, a drive motor control signal is generated accordingly, and according to the control signal of the computer control unit, the rotating disc 15 coupled with the drive motor 12 is rotated to release the twisted fiber fabric automatically. There is so.

That is, as shown in FIG. 1, the present invention obliquely projects a plurality of parallel linear lights 26 projected through a plurality of parallel linear light generators 27 formed in the twist recognition unit 16 of the fiber fabric on the twisted fiber fabric. One step of tilting and projecting;

A two-step process in which the curved stripe shape that the plurality of parallel linear lights 26 make in the fiber unit is recognized by the image camera 14 installed in the twist recognition unit 16 of the fiber fabric;

A three step of determining, by the computer controller 17, the twisted direction and degree of the fiber fabric by analyzing a curved stripe pattern that the plurality of parallel linear lights 26 are made on the fiber fabric twisted;

When the rotating disk 15 is rotated according to the twisted direction and the degree of the fiber fabric by the rotation of the drive motor 12, the fiber fabric tightening roller 11 formed on the rotation disk 15 is rotated to twist the fiber fabric. It is composed of four steps to be released.

At this time, the rotating disk 15 is a structure generally used in a conventional scavenger, etc., it can be freely rotated 360 ° by a bearing (not shown) device.

On the other hand, a plurality of parallel linear light is generated using a plurality of line-laser beam generator 13 as shown in FIG. 3 or in the light source lamp 23 formed inside the parallel linear light generator 27 as shown in FIG. Light sources such as infrared rays, ultraviolet rays, and electric lights that are emitted may be generated by passing through a plurality of gap grooves 25 formed in the slit light shielding plate 24.

In this situation, the image camera 14 preferably uses an electronic image sensing device using a CCD or CMOS sensor, which is a semiconductor device, to accurately detect the twist of the fiber fabric and convert it into an electrical signal.

In addition, according to the case where the scacher applied to the system of the present invention is installed in the field, the maximum processing speed should be the same as the tenter because it may be directly connected to the tenter to simplify the fiber processing process (about 150 m / min). In addition, due to the different operation speed of the tenter according to the type of the fiber fabric, the processing speed of the fiber fabric twist release system of the present invention also maintains the same performance as the tenter. Naturally, the proportional control method should be designed.

When the fiber fabric twist release system configured as described above is attached to a plurality of movable box-type structures in which guide rollers are installed as shown in FIG. 8, a fiber fabric twist release machine (vision scatcher) having a completely different form from a conventional scorch is formed. As a result, it can be manufactured in a small form with a small size and can be moved as well as a machine.

However, the application of the present invention is not limited thereto, but may be applied to a conventional conventional fixed scorch type as shown in FIG. 5 (a) to detect and release the twisted state of the fiber fabric, as shown in FIG. 5 (b). The conventional scotcher may be improved and used in a low form, may be made integral with the dehydrator as shown in FIG. 7, or may be made by attaching to a dyeing machine as shown in FIG. 6 (a). It can be easily attached to other kinds of textile machines, such as one-piece dyeing machines, and can form twists of textile fabrics without the help of conventional scotchers.

Referring to the operation and effects of the present invention made of the above configuration in detail as follows.

First, as shown in (a) and (b) of FIG. 5, the fiber fabric 19 moved by the moving means 20 in the dyeing machine 21 or the dehydrator 22 may be unfolded evenly by the scotcher 10. do.

On the other hand, the fiber fabric stored in the moving means 20 is to pass through the twist recognition portion 16 of the fiber fabric via a plurality of conventional guide rollers.

At this time, the front disc of the twist recognition unit 16 is formed with a rotating disk 15 coupled with the fiber fabric tightening roller (11).

In addition, a plurality of parallel linear light generators 27 are fixed at predetermined positions of the outer periphery of the twist recognition unit 16 of the fiber fabric, and the image camera 14 is provided inside the fiber yarn twist recognition unit 16. Image processing was performed in real time to transmit the data to the computer control unit 17.

That is, a plurality of parallel linear lights 26 projected on the surface of the fiber fabric introduced into the fiber fabric twist recognition unit 16 form a curved stripe image on the fiber fabric twisted, and the image information is an image camera. It is transmitted to the computer control unit 17 in real time through 14 so that the computer control unit analyzes the warping and twisting of the fiber fabric.

When the computer control unit (not shown) generates a control signal capable of correcting the twisted and twisted fiber fabric according to the analyzed information, the rotating disc 15 having the fiber fabric tightening roller 11 formed in accordance with the control signal. The driving motor 12 is connected to the rotating and the rotating disk 11 is rotated together so that the distortion of the fiber fabric can be released.

If the twist recognition unit 16 of the fiber fabric is formed to be movable as shown in Fig. 6A, it may be configured on the side of the rapid dyeing machine 21, or it may be fixed as shown in Fig. 6B to be a rapid dyeing machine. It can also be comprised integrally with (21).

In the above situation, the fiber fabric discharged through the inside of the rapid dyeing machine 21 is moved into the fiber fabric twist recognition unit 16 through the fiber fabric tightening roller 11 formed integrally with the rotating disk 15. The curved surface of the fiber fabric moving in a twisted state through a plurality of parallel linear light 26 projected by a plurality of parallel linear light generators 27 formed in the twist recognition unit 16 and an image camera. After measuring in real time, the state is converted into an electrical signal and transmitted to the computer control unit 17, the computer control unit determines the twisting direction and the degree of warpage of the fiber fabric and generates a drive motor 12 control signal to generate the fiber By rotating the rotating disk 15 to which the appointment roller 11 is attached, the twist of the fiber fabric can be automatically released.

In addition, since the fiber fabric dyed as shown in Figure 7 is moved to a circular dehydrator 22 using a centrifugal force to dehydrate the fiber fabric is twisted with each other.

At this time, the dehydrated fiber fabric passes through the twist recognition unit 16 of the fiber fabric formed on the upper side of the dehydrator 22 to release the twist of the fiber fabric.

The fiber fabric dehydrated in the dehydrator 22 in the above situation is moved to the inside of the fiber fabric twist recognition unit 16 through the fiber fabric tightening roller 11 formed integrally with the rotating disk 15, the twist recognition unit Measurement of the curved surface of the fiber fabric moving in a twisted state through a plurality of parallel linear light 26 projected by a plurality of parallel linear light generators 27 formed in the image 16 and the image of the image camera in real time Then, the state is converted into an electrical signal and transmitted to the computer control unit 17, the computer control unit determines the twist direction and the degree of twist of the fiber fabric and generates a drive motor 12 control signal to the fiber fabric tightening roller ( 11) by rotating the rotating disk 15 is attached to the fiber can be automatically untwisted and moved to the tenter.

And, by forming a plurality of twist recognition unit 16 of the fiber fabric as shown in Figure 8 it can be configured a new scorch that can effectively correct the twisted fiber fabric. When the twist recognizer 16 of the first fiber fabric releases the twist of the twisted fiber fabric, the twist effect is not completely eliminated, but goes to the rear of the twist recognizer 16 of the fiber fabric. If the fiber is twisted to the left and the twisted to the right, there is no problem in the operation of the system. However, in some cases, the twisted state of the fiber fabric may continue to the left or the right side. In this case, the twisted effect of the accumulated fiber fabric may be no longer operated after the twisted recognition portion 16 of the fiber fabric passes. It is impossible to twist the fabric. In this case, the machine must be stopped and a human twisted fabric must be released. However, if the twist recognition unit 16 of the second fiber fabric is released in the opposite direction to the twist effect of the fiber fabric accumulated over the twist recognition unit 16 of the first fiber fabric, the fiber fabric can be continued without stopping the machine. It is. As described above, if the twist recognition unit 16 of the fiber fabric is appropriately increased according to the type of fiber fabric work, it is possible to make a scotcher (vision skacher) that does not need to stop the machine in any case according to the twisted state of the fiber fabric. do.

As described above, the present invention measures the curved surface of the fiber fabric moving in a twisted state through the images of the plurality of parallel linear light 26 and the image camera 14 in real time, and then converts the state into an electrical signal. After transmitting to the computer control unit 17, the computer control unit 17 determines the twisting direction and the degree of warpage of the fiber fabric, and generates the drive motor 12 control signal according to the rotation of the fiber fabric tightening roller 11 attached thereto. By twisting the disc 15, the twist of the fiber fabric is to be automatically released.

The present invention described above is capable of various substitutions and modifications within the scope without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains, the above-described embodiments and the accompanying drawings. It is not limited to.

As described above, in the present invention, a line-laser ray generator or a light source lamp and a slit light shielding plate for generating a plurality of parallel linear lights in order to detect the twist of the fiber fabric are integrally formed with the image recognition camera in the twist recognition unit of the fiber fabric. The video data of the video camera is composed of the computer control part to analyze. Therefore, the configuration is simple, so there is no big problem to make it fixed and mobile. In addition to the existing scavenger, other fibers such as various dehydrators, dyeers, centuries, tenters, etc. There is also a feature that can be attached and applied to machinery.

In addition, applying the twisting system of the fiber fabric using a plurality of parallel straight light beams to the scavenger can process the fiber fabric at a faster speed than the conventional scavenger, thus greatly increasing the time required for the work (more than 2-3 times). In addition, the machine can be shortened and the accuracy of the machine can be reduced, thereby reducing the number of workers who manage the machine. Therefore, the user who uses the scotcher is economically profitable. In addition, from the perspective of the producer of the scavenger, even if the machine structure is reduced, the performance of the machine is improved compared to the conventional scavenger, so that the production cost required for the machine production can be reduced, and the maintenance is convenient, thus the work efficiency and production There is an effect that can increase the efficiency.
