Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and an apparatus for peeling off a cattle trellis in a crested part of the crest part by injecting liquid or gas at high pressure during the peeling of the cattle trellis. It is characterized by:

Traditionally, when forming the crests in montsuki, glutinous rice glue (makidana) is placed on the crest part of the fabric from the front and back, and this glue prevents the dye from penetrating the fabric, and then the fabric is dipped in black or other dyes and dyed. , I was peeling off the racks.

However, when dyeing Makidana, it is necessary to prevent the dye from penetrating into the crest, so as shown in Figure 1, Makidana ■■ is provided in a relatively thick layer on the front and back of fabric ■, and then further layered on top of it. Waterproof paper must be provided, and since the troughs are stuck to the fabric and cannot be removed easily, at present, after dyeing and washing with water, a skilled worker wears a nail-like peeling tool on his or her finger. The person uses his/her nails to peel off only the raised part of the wood shelf so as not to damage the fabric. Since this work requires skill and caution, it takes more time than other dyeing processes, and this process has been a bottleneck in improving production capacity.

In view of the above-mentioned current situation, the present invention is based on the results of various experiments and is designed to automatically remove the trellis. That is, in the present invention, we considered using hot water or water to peel off the bokutana, and as a result of experiments using various nozzles at various pressures, we found that hot water or water at a pressure of 5 to 5 kg/ci was used from a slit-shaped nozzle By spraying water diagonally above the fabric onto the boundary between the fabric and the shelving rack, the raised shelving rack can be smoothly peeled off. This method is completely new in the tie-dye industry; if the pressure of hot water, water, or air is too low, it will take a long time, and if the pressure is too high, it will distort the weave of the fabric and damage it. result. Therefore, it is preferable to spray water several times for a certain period of time at a pressure that does not damage the fabric to peel off the mokudana.

The above-mentioned means can be applied not only to liquids such as hot water or water, but also to gases, and it is also possible to separate the trellis by injecting compressed air from a slit-shaped nozzle.

Next, one embodiment of the apparatus of the present invention will be described based on the drawings.

Figure 2 is a side view schematically showing the device of the present invention, where ■ is a mount ■
The rotating drum is installed at the top of the rotating drum, and the guide rolls are installed at the front and rear of the rotary drum shaft. Kugushi is wrapped around the upper half of the rotating drum.
It passes through a guide roll ■ and is wound onto a take-up roll [phase]. 00... is an injection nozzle equipped with a slit-shaped injection hole provided in the space above the rotating drum. It is installed so that it sprays onto the drum surface at a substantially constant angle in the opposite direction to the rotational direction of the drum. A large number of these spray nozzles are installed to spray water or air uniformly over the entire surface of the fabric, and are configured so that the fabric can be washed as well as peeling off the shelving rack. Pressure water or compressed air is sent to the pipe @ through a high-pressure hose @.

Therefore, high-pressure water or compressed air is repeatedly sprayed from a large number of injection nozzles ■ onto the fabric ■ that is wrapped around the upper part of the outer circumference of the rotating drum ■ so as to hit the mokidana part at a constant angle. As a result, the surface makidana ■ protruding from the fabric ■ is gradually peeled off and washed away.

In addition, regarding the backside shelf, you can peel it off by turning the fabric over again and going through the same process as above, or use the same rotating drum or spray nozzle as above as a device to remove the If provided as such, the back side of the shelving rack can be continuously peeled off.

In the above embodiment, the fabric is wrapped around a rotating drum and the fabric is peeled off while being fed. However, it is also possible to feed the fabric using a flat conveyor instead of the rotating drum. , The above-mentioned Makidana also includes a resist dye number made of an appropriate synthetic resin, etc., when dyeing by applying the resist dye to both the front and back sides of the fabric to cover the crest. Needless to say, the method and apparatus of the present invention can be applied to the same.

As described above, the present invention allows for easy peeling of the shelving rack, and the device has a simple structure, and can be peeled off continuously and quickly without shifting or damaging the fabric. It is possible to peel off and clean the bamboo trellis, which is revolutionary in the tie-dye industry and has high utility value (high industrial applicability).

Claims (1)

[Scope of Claims] 1) A method for peeling a mokudana with a crest on it by injecting g1 or gas under high pressure onto the makidana raised on the surface of the fabric. 2) A crested Makidana peeling device characterized by being equipped with a device for moving the fabric and a device for spraying high-pressure liquid or gas from diagonally above the fabric through a plurality of spray nozzles.
