Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust removing device for removing fiber yarn debris, dust, and the like which are obstacles in processing a fabric surface.

[0002]

2. Description of the Related Art Dyeing is one of the important steps in various processing of fabric surfaces. For example, there is a direct printing method in which a printing paste prepared by mixing a dye, an auxiliary agent, a sizing agent, and the like is imprinted on a cloth surface by a printing machine with a die, steamed, and the dye is penetrated into the cloth surface.

[0003] As described above, when a color pattern is applied to a cloth surface by a printing machine or the like, if fiber lint or dust adheres to the cloth surface, the color of the printing paste on the part becomes incomplete. ,
It can cause defective products. Therefore, dust removal work on the cloth surface has conventionally been a necessary step. As the main dust removal method,
There are the following two.

First, there is an apparatus using a suction fan. As shown in FIG. 3, an example of this is that the suction slit 31 at the tip of the air suction nozzle 32 connected to the suction fan 33 is brought into contact with the hanging cloth surface 30 to absorb the surface, and the cloth surface 30 is sucked. By proceeding,
It continuously absorbs fiber yarn waste and the like on the cloth surface 30 together with air.

[0005] Further, there is one using an adhesive tape.
This is, for example, as shown in FIG. 4, a plurality of adhesive rolls 4 each wound around a commercially available adhesive tape.
1 are rotatably arranged on the same circumference to form a roll assembly 42.

[0006] By rotating the cloth surface 40 running on one of the adhesive rolls 41 of the roll aggregate 42 in contact with and rotating it, fiber yarn debris on the cloth surface 40 is continuously adhered to the adhesive tape surface and removed. be able to. When the adhesive strength of the adhesive tape surface of the adhesive roll 41 decreases, the roll aggregate 42
Is rotated, and the adhesive roll 41 having reduced adhesive strength is moved and replaced with the next adhesive roll 41, and the dust removing operation on the cloth surface 40 is continued.

[0007]

However, in the above-described conventional dust removing apparatus, dust removal on the cloth surface is insufficient. That is, in the case of using the above suction fan, it is difficult to remove the fiber lint entangled with the fabric weave by suction, and a very powerful suction fan is required to remove such lint. I do. However, a powerful suction fan is expensive, and there is a cost problem in mounting it on a dust removing device.

[0008] Further, in the dust removing apparatus using the above-mentioned adhesive tape, it is possible to remove the fiber lint entangled with the woven texture by the adhesive force, but the lint accumulates on the roll surface. And the adhesive strength is extremely reduced.

Therefore, in order to always maintain a strong adhesive force capable of removing fiber yarn debris entangled with the woven structure, the adhesive roll must be frequently moved and replaced, and the work of replacing the adhesive roll is also troublesome. Related. On the other hand, it is difficult to accurately determine the time at which the adhesive force decreases, and the selection of the roll replacement time is unstable, so that the dust removal efficiency is also unstable.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a cloth dust removing apparatus having a configuration capable of maintaining high dust removing efficiency at a low cost.

[0011]

In order to achieve the above object, a cloth dust removing apparatus according to the first aspect of the present invention comprises:
A cloth dust remover having a suction fan, a suction nozzle connected to the suction fan, and a slit provided at the tip of the nozzle and in contact with a running cloth to suction unnecessary objects on the cloth. In the vicinity of the opening of the slit, there is provided vibration applying means for applying vibration to the cloth surface.

According to a second aspect of the present invention, in the dust removing apparatus for a cloth surface according to the first aspect of the present invention, the vibration applying means has an upper edge positioned on an upper surface of the opening of the slit. And a vibration generator that vibrates the vibrator plate in the slit opening in the running direction of the cloth surface.

In the present invention, since the suction and dust removal is performed while vibrating the cloth surface by the vibration imparting means, the fiber yarn debris entangled with the woven fabric, which has been difficult with a conventional dust removal device that merely suctions, can be used. In addition, the entanglement is loosened by the vibration and released, so that the entanglement can be easily removed.

As the vibration applying means, as described in the second aspect, a configuration in which the vibrator plate is vibrated in the cloth traveling direction in the slit opening by the vibration generator is simple. In the cloth surface area exposed in the slit opening and where the upper end of the vibrator plate is in contact, the upper end of the vibrator plate slides back and forth with the vibration of the vibrator plate, and fiber yarn debris entangled with the woven tissue is entangled by the vibration of the cloth surface Is loosened, and is detached by being pulled directly out of the entanglement by sliding, and is quickly removed by suction.

As described above, in the dust removing apparatus according to the present invention,
Without the use of a special powerful suction fan, which would increase the cost, fiber yarn debris entangled with the woven fabric, which was difficult in the past, can be easily removed, and there is no need to move or replace parts such as adhesive rolls. High efficiency and good dust removal on the cloth surface is possible at low cost.

In order to maintain efficient suction and dust removal over the entire cloth surface, it is necessary to maintain a good suction state of the slit opening on the cloth surface. Therefore, it is desirable to block the transmission of the vibration by the vibration applying means to the slit. As the vibration blocking means, for example, a configuration in which a vibration absorbing member such as a spring or an elastic member is interposed between the vibrator plate and the slit body is simple.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As one embodiment of the present invention, a dust removing device having a vibrator plate vibrating in the cloth traveling direction by a vibration generator in a slit opening is shown. 1A is a front view showing a schematic configuration of the entire apparatus, FIG. 1B is a longitudinal sectional view of a portion XX in FIG. 1A, and FIG. 1C is a partially enlarged sectional view of a slit opening. FIG. 2 is a longitudinal sectional view taken along the line YY in FIG.

In this apparatus, a nozzle body 1 is connected to a suction fan (not shown) via a suction duct 7.
The nozzle body 1 is provided at the upper end of a substantially housing-shaped body frame 8.
Slits 9 are formed across the width of the cloth surface 3 so as to be attracted to the lower surface of the cloth surface 3 running in the longitudinal direction and to suction unnecessary substances on the surface.

In the main body frame 8, a vibrator plate 10
A vibrator frame 11 for holding and fixing this at a lower portion is provided. The vibrator plate 10 is held such that the upper end edge is located on the upper surface inside the opening of the slit 9, and the vibrator frame 11 is supported by the main body frame 8 via the vibration absorbing spring 12 at both ends.

The vibration absorbing spring 12 causes the vibration of the vibrator plate 10 and the vibrator frame 11 to vibrate.
Without being transmitted to the slit 9 during the suction operation.
The state of contact with the cloth surface 3 is always stable and good suction is promoted.

Further, the vibrator frame 11 is provided with a plurality of connecting pins 14 extending downward through the bottom of the main body frame 8, and a lower end of the plurality of connecting pins 14 generates a vibration generated by a vibration motor. The support frame 16 on which the container 13 is mounted is connected. The connecting pin 14
A gap between the main body frame 8 and the through hole at the bottom of the main body frame 8 is hermetically insulated by a rubber packing 15.

The length of the slit 9 is set slightly shorter than the width of the cloth surface 3 to be dust-removed. Thereby, the opening of the slit 9 can be covered with the cloth surface 3 and the inside of the main body frame 8 can be sealed. When the suction fan is driven in this closed state, the inside of the main body frame 8 becomes a negative pressure, and a slight air suction starts from the opening of the slit 9 through the cloth surface 3, and at the same time, the exposed surface of the cloth surface 3 is sucked by the slit 3. At this time, when the vibrator plate 10 is vibrated, the upper end edge of the vibrator plate 10 reciprocates at a high speed with respect to the exposed surface of the cloth surface 3 as shown in FIG.

The frequency and amplitude of the vibration generator 13 can be arbitrarily adjusted, and are suitable for each dust removal step based on various conditions such as the material of the cloth surface 3 and the traveling speed. What is necessary is just to select and set a numerical value.

The vibration of the vibrator plate 10 is caused by the vibration generated by the rotation of the eccentric weight in the vibration generator 13 so that the vibration generator 13 swings along with the support frame 11 in the running direction of the cloth surface 3 (indicated by an arrow in the drawing). This vibration is caused by reaching the vibrator frame 11 via the connecting pins 14 connected to the support frame 11. The dust removing operation of the cloth surface 3 in the dust removing apparatus having the above-described configuration is as follows. First, the tip of the cloth surface 3 or the dust removal start part of the cloth surface 3 is placed on the main body frame 8 so as to cover the slit 9 from a cloth feeding device (not shown).

In this closed state, the driving of the suction fan and the vibration generator 13 is started. The exposed surface of the cloth surface 3 covering the opening of the slit 9 is sucked, and unnecessary matter such as fiber lint adhering to the cloth surface 3 while being reciprocated by the upper edge of the vibrator plate 10 is removed together with air by the suction duct 7. It is sucked to.

Therefore, when the cloth surface 3 travels, the suction dust removal proceeds continuously in the longitudinal direction over substantially the entire width region of the cloth surface 3. Further, even if the fiber waste adhering to the cloth surface 3 is entangled with the weave, the yarn waste is separated from the entanglement by the reciprocal sliding of the upper edge of the vibrator plate 10,
It is easily sucked. Therefore, during the operation of the dust removing device, reliable dust removal is always performed efficiently.

In the above-described embodiment, the vibrator plate 10 is configured to vibrate in the running direction on the cloth surface, that is, substantially in the horizontal (horizontal) direction. May be used. Also,
The means for applying vibration to the cloth surface according to the present invention is not limited to the means for directly contacting the tip of the member as described above, but may be any as long as it can vibrate at least the slit contact area of the cloth surface.

[0028]

As described above, according to the dust removing device of the present invention, it is possible to use the dust removing device without using a particularly powerful suction fan.
Adhesives on the cloth surface, such as fiber yarn debris entangled with the weaving structure, which have been difficult in the past, can be easily removed by suction, and there is an effect that high dust removal efficiency can be achieved with a configuration in which costs are suppressed.
