Description

Safety device for a textile straightener {a safety device for a textile reforming machine}

The present invention relates to a safety device for a wood cutting machine, and more particularly, by selecting a suitable position of a conventional wood straightening machine, that is, any one of the upper, lower, or central portion of the wood cutting machine, and installing a predetermined safety device. Tenters, including mangle rollers, which are heavily loaded on the fabric due to carelessness or electrical error of the worker during the process of conveying the fabric, or a malfunction of a circuit or machine, or are installed on the same line as the fabric corrector. The fabrics are reversely wound on several rollers of the fabric, so that the fabric can be automatically cut when the fabric has already passed through the fabricator, and a huge load acts on the fabric to affect the surrounding machinery such as the fabricator. To prevent deformation or damage of various devices or parts such as peripherals, tenters, etc. Be able to, but you want to make this a variety of fibers, including drapery fabric braces can prevent damage and loss of quality of life as well as the extension of machining along.

As is well known, the wood cutter is a device for improving the quality of the fabric by correcting the weft and warp of the fabric. In addition, it is common to use the woodworking calibrator connected to a tenter machine.

On the other hand, the tenter machine is a device for drying and setting the fabric at the same time, looking at its configuration, the texture guide, mangle, speed compensation device, siding in order to smoothly transfer and dry the dyed fabric It is composed of many other devices besides straighteners, pinning devices, hot air dryers, etc.

However, the tenter machine including the above-mentioned wood cutting machine is accompanied by the following disadvantages, such as expensive equipment is easily damaged or precision is greatly reduced by the following problems, and also the defect and the quality of the fabric is greatly reduced.

That is, in the process of drying, straightening and setting the fabric while passing through the tenter machine, sometimes the fabric being transported to various rollers including mangled rollers is not circulated smoothly and is wound up. When the fabric is wound, the conveyed and passed fabric is pulled in the reverse direction, and thus receives a very strong load. As a result, a very strong tension is applied to the fabric, and various rollers and bearings and parts supporting the same are applied by this force. It is easily deformed or broken, and in severe cases, it causes breakage and deformation of the wood cutting machine, which leads to excessive repair costs, a significant drop in the precision of the machine, and a loss of fabric.

In addition, the causes of damage to the equipment and fabric as described above are caused by various factors, such as due to negligence of the operator, malfunction of the machine or circuit, and electrical errors. As a result, the precision of the machine is greatly degraded, which leads to deterioration of the fabric, quality degradation, and excessive maintenance costs.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, in particular to install the safety device of the subject innovation in the appropriate position (for example, the upper or lower or inner central part of the wood braces), The upper and lower two fabric guide rollers and tension rollers for guiding the fabric, the guide rod for guiding the tension roller is conveyed back and forth, and the fabric cutting cutter fixedly installed between the guide rods, and the tension is inserted into the front and rear of the guide rod It consists of a strong compression spring that allows proper elasticity to act on the rollers, and it cuts the fabric automatically when weaving the weft while the weaver is corrected by the wood straightening machine, thereby stably protecting textile machinery such as wood straighteners and tenters. At the same time, it aims to minimize deformation and loss of fabric. It is.

In the conventional wood straightening machine composed of a plurality of fabric meandering correction roller 10, the guide roller 20, the curved correction roller 30, a plurality of weft detector (40),

Configure the safety device (1) on the lower side of the inside of the wood braces,

The safety device (1)

Guide rods (2) (2a) fixed to upper and lower sides of inner wall surfaces of both side frames of the woodworking cutter body (Y);

A slider (4) (4a) supporting the tension roller (3) (3a) while being assembled to the guide rods (2) (2a);

A compression spring (5) (6) of strength and weakness, which is assembled at the front and rear of the guide rods (2) and (2a) to control the backward of the sliders (4) and (4a) and at the same time prevent shock;

A cutting cutter (7) installed between the guide rods (2) and (2a) so that the fabric is automatically cut when the tension roller reaches its limit in the process of reversing the tension roller as the overload acts on the fabric;

And it is installed in the upper and lower portion of the safety device is composed of guide rollers (8) (8a) and cutting guide rods (9) (9 ') to guide the fabric.

Reference numeral 50 denotes a tenter group, 60 denotes a mangle, and 70 denotes a fabric input device.

The present invention configured as described above is preferably installed at an appropriate position of the conventional wood straightener, preferably installed at the bottom of the wood straightener so that when the fabric is overloaded, the fabric is preferably cut in the weft-corrected state.

In addition, when explaining the operation of the present invention,

The fabric is a guide roller (8) and tension roller (3) (3a), which constitutes the safety device 1 of the present invention through the fabric guide roller 20 and the meandering correction roller 10, the curved correction roller 30, Then, the roller is circulated again through the guide roller 8a. At this time, when a very strong tension such as a mechanical error or an electronic problem occurs, such as an electric error or a conveyance error of the fabric, the fabric cannot be conveyed any more, tension is applied. The slider (4) (4a) supporting the tension roller is gradually reversed by the load of the raw material acting on the roller (3) (3a), so that the slider (4) (4a) touches the cutting cutter (7). When the fabric is inclined in one direction and at the same time the fabric is in contact with the cutting edge of the cutter 71 formed at the same time, the fabric is stretched by an auxiliary device that easily guides the cutting of the fabric, that is, cutting guides (9) (9 ') It was cut smoothly without being pushed back It releases the tension, and thus it is possible to reliably protect machines such as fabric cutters, tenters, mangles, etc. without being damaged, damaged, or broken, while minimizing the loss or deformation of fabrics.

In addition, when the fabric, which was heavily loaded as described above, is cut by the cutting cutter 7, the tension rollers (3) and (3a) protrude reflexively at the same time as the cutting. Compression spring (6) having a relatively weak elasticity can be installed to minimize the impact acting on the wood braces itself, it is to be able to reliably protect the stabilizer including wood braces.

On the other hand, the cutting cutter 7 of the present invention can be manufactured in various types, as shown in the left and right portion of the cutter support frame 72 formed of the cutter "71" inclined to one side blade edge When installed opposite to each other, the load is severely acted on the fabric by a malfunction or error, and accordingly the tension roller (3) (3a) is forced to the cutting cutter position by the tension of the fabric and the fabric comes in contact with the cutting cutter The cutting cutter is to cut the fabric in stages rather than cutting the entire fabric at once so that the fabric can be cut more smoothly.

As described above, the present invention is installed in the woodworking braces so that the load or tension is very severely acted by the electrical error, physical error, malfunction, etc., so that it can automatically cut when the load or tension is reached By doing so, it is a very useful invention that the effects such as to prevent breakage or deformation of the tenter group, mangles, etc., such as braces, to minimize the deformation loss of the fabric.
