Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and device for removing lint from a towel, in which air is jetted from one side of the towel in the device to cause the towel to flap in a wave pattern, thereby blowing off the lint. It is characterized by removal.

Conventionally, in the towel manufacturing process, lint and dust that adhered to the towel surface were removed by pressing one end of the towel spread out on a table with one hand, and spraying it diagonally above the towel surface with an air spray gun held in the other hand. Blow compressed air from
The process of blowing lint and dust forward with the force of the jet of air was carried out twice on each towel, on the front and back sides.

However, this work causes serious problems such as lint and cotton dust generated from the towels being scattered throughout the room, which is unhygienic and harms the health of the workers.

Particularly in the case of pass towels, the heavier they are, the more expensive they are, and for this reason, some towel manufacturers include fine stone powder in their towels as an extender. There is also a high risk that fine stone dust will fly up at the same time and cause a sand plain problem.

The present invention was devised in view of this situation, and is designed so that once a towel is obtained and set in a predetermined position, subsequent air injection and collection of lint and dust are automatically carried out within one device. This is what I did.

That is, the first aspect of the present invention is a novel method for removing lint, in which one end of a towel is fixed in a vertical or horizontal state, and a turbo fan blows air from this fixed side along both sides of the towel. In this method, the lint adhering to the towel surface is lifted off the towel surface by flapping the towel in a wave pattern, and the lint is blown forward by the air sent in from the turbo fan, and then sucked up and removed by a dust collector. .

There are various ways to make a towel flap using the air jet from a turbo fan, but the simplest method is to place one end of the towel in the center of the turbo fan's air jet port without any special modifications. The towel then flutters in waves along its entire length.

Although the principle behind this is not clearly understood theoretically, it is thought that air at a constant pressure flowing parallel to both sides of the towel interferes with each other, causing the towel to ripple.

The second aspect of the present invention is an apparatus for removing lint from towels using the above-mentioned principle, and is of a type in which the towel is installed in a suspended state and air from a turbo fan is jetted downward from above. It is.

An embodiment of the apparatus of the present invention will be described below with reference to FIGS. 1 to 3.

In the figure, reference numeral 1 is a cloth belt, which is stretched endlessly over a distance of about three times the width of the towel 2 so that the cloth surface rotates vertically, and the cloth belt and the belt surface are in pressure contact with each other. A cloth belt 3 is similarly provided at a distance approximately twice the width of the passed towel.

A casing 5 having a height slightly longer than the length of the pass towel is provided below the press-contact portion 4 between the cloth belt 1 and the cloth belt 3 so as to surround the press-contact portion.

The length of the casing 5 is slightly larger than the width of the pass towel, and the width is slightly wider than the diameter of the belt pulley 6, but these dimensions are not particularly limited.

On both sides of the casing 5, a slit 6 for passing the belt at the top and a slit 7 for passing a towel (hereinafter simply referred to as a towel) at the bottom thereof are integrally provided as one slit. A contact plate 8 is provided on the back of one belt, and a belt pressure contact plate 10 is provided on the back of the other belt with a spring 9 interposed between it and the inner surface of the casing, so that the cloth belt and the cloth belt are always connected. moves in a press-contact state.

In the upper center of the casing 5 is a high-speed turbo fan 1.
1 is installed so that high-speed air is blown across the pressure contact part 4 of both belts, while an exhaust port 12 is provided at the bottom of the casing, from which a dust collector ( (not shown) to collect dust such as lint.

Reference numeral 14 denotes air guide plates provided on both the front and rear sides of the towel in the casing, which are provided in order to make the towel flap more efficiently, but are not necessarily necessary, and if the wind power of a high-speed turbo fan is appropriate. If so, a sufficient fluttering phenomenon can be guaranteed even without a guide plate.

Reference numeral 15 denotes a belt drive motor 16, which is a speed reducer and is transmitted to the belt pulley 6 via the belt 7 and gears 1B and 19 to rotate the cloth belt 1 and the cloth belt 3 at the same speed.

Reference numeral 20 denotes a brush roll provided in contact with the clothing belt 1 for pressing and fixing the towel against the clothing belt, and reference numeral 21 for automatically separating the treated towel from the clothing belt. 22 is a rubber plate provided on the inner surface of the slit 7 of the casing to reduce air leakage in the casing, and 23 is a transparent door on the front of the casing for viewing the inside. Although it is designed to enable inspection, this is not necessarily necessary.

Next, the effects of the above-described first embodiment of the present invention will be explained.

While slowly rotating the belt, manually press the top edge of the towel 2 with lint or the like on it in the longitudinal direction from the front of the device to the cloth belt to fix it.

This towel is suitably pressed at the left end by the brush roll 20, then makes a U-turn, passes through the slit 7 of the casing 5, and enters the casing.

Inside the casing, a high-speed turbo fan blows high-speed air from the top along both the front and back sides of the towel, causing the towel to flap violently as it moves, removing lint and other particles attached to the towel. At the same time, fine stone powder and the like are separated from the towel and blown downward by high-speed air, and collected in a dust collector from an exhaust port 12 via a dust hose 13.

The towel from which lint has been removed comes out of the casing through the other slit, where the towel is automatically separated by a separation guide 21 below the clothing belt 1 that intersects the clothing belt at an acute angle. It separates from the clothing belt and falls.

Next, another embodiment of the present invention, that is, a third invention of the type in which air from a turbo fan is jetted in a substantially horizontal direction while conveying the towel horizontally on a belt conveyor, is shown in FIGS. 4 to 6. I will explain based on.

In the figure, reference numeral 25 denotes a cloth belt, which is stretched endlessly over a distance of about 4 to 5 times the width of the pass towel 2 so that the belt plane rotates horizontally. Belt conveyors 26 of equal width are provided in parallel.

A cloth belt 27 is provided in the center of the cloth belt so as to be in pressure contact with the cloth belt at a distance approximately twice the width of the pass towel.
A casing 29 is provided to surround the pressure contact portion and the upper part of the belt conveyor 26 at the rear.

The casing 29 may be formed to completely surround the upper surface of the cloth belt 25 and the belt conveyor 26, or the upper surface of the belt conveyor may also serve as the bottom surface of the casing as shown in the figure.

Naturally, on both sides of this casing, there are provided at least slits 30 through which the press-contact portion of the cloth belt and the cloth belt, the top surface of the belt conveyor, and a pass towel (hereinafter simply referred to as a towel) placed above the belt conveyor pass. A high-speed turbo fan 31 is provided at the front of the casing, and an exhaust port 32 leading to a dust collector (not shown) is provided at the rear.

Reference numeral 33 in FIGS. 4 and 5 is a towel separation guide provided at one end of the clothing belt 27, and is provided just above the towel in order to automatically separate the treated towel from the clothing belt 27. It is something that exists.

Reference numeral 34 in FIG. 5 is a belt pressure contact plate provided on the back surface of the upper part of the cloth belt 25, which is always pressed upward by a spring 35 with a constant pressure to prevent the towel inside the casing from coming off from both belts. However, the spring is not necessary.

Note that 36 in Fig. 6 is a front flap made of a soft sheet to prevent air leakage provided in the slit on the side of the casing, and is intended to make effective use of the injected air, but is not necessarily required. .

Further, in this embodiment, the driving means for the belt and the belt conveyor are omitted in the drawings.

Next, the effects of the second embodiment of the present invention described above will be explained.

While slowly rotating the belt and the belt conveyor in the direction of the arrow, manually spread the towel 2 with lint etc. attached on the upper right side of the belt conveyor 26, and place one end of the near side in the longitudinal direction of the towel on the cloth belt 25. When the cloth is placed on the cloth belt 27 as the belt moves, it gets stuck in the cloth belt 27 and is sent into the casing 29.

Inside the casing, the high-speed air generated by the high-speed turbo fan 31 is injected backward from the lower front toward the upper side, causing the towels on the belt conveyor to flutter as shown in Figure 6. Lint and other fine stone powder, etc., are separated from the towel and simultaneously blown backward by high-speed air and collected in a dust collector from the exhaust port 32 via the dust hose.

The towel from which lint has been removed comes out of the casing through the other slit, but since a towel separation guide 33 is provided just above the towel at the end of the clothing belt, the towel is separated by this separation guide. Since they are automatically peeled off from the clothing belt 27 and sent to the left end on the belt conveyor 26, they can be pulled together before falling, or if left unattended, they fall and accumulate.

Note that the cloth belt in the above embodiment is a cloth belt with countless needles implanted on its surface, but in the present invention, it is not necessarily necessary to use a cloth belt; for example, a commercially available roller chain may be used. The needle may be attached to an attachment, or other appropriate clamping means may be used.

As mentioned above, the present invention automatically brushes off the lint etc. attached to the towel in the casing and at the same time forcibly collects the lint etc. in the dust collector, so it is hygienic and Since the work is simple, it is useful for significantly improving the working environment, and the present invention is also useful for removing debris not only from pass towels but also general small towels, wrapping cloths, and other fabrics, and has high industrial applicability. It is something.
