The cloth 2 is a rotary drum 1.
1b provided on the front outer peripheral wall of the rotating drum 1
With the opening and closing plate 1c opened, the sheet is folded back and folded while being set, and then the washing liquid 3 is filled. Therefore, the cloth 2 and the washing liquid 3 are filled only up to about the lower half inside the rotary drum 1, and the upper half is empty. Therefore, the opening / closing plate 1c is closed to rotate the cloth 2 and the washing liquid together with the rotary drum 1. Then, the cloth 2 falls inside the rotating drum 1 from the upper side to the lower side or jumps and repels, and the twisted, bent, entangled, or broken without holding the set state.

Further, a rib 1a for holding a piece of material is projected inside the rotary drum 1. However, a part of the piece of piece of material 2 that jumps onto the rib 1a is caught or twisted, or the rib 1a. Also, a part of the cloth 2 collides with the inner peripheral surface of the rotary drum and friction occurs.

As described above, when the cloth 2 is extremely entangled in the rotary drum 1 and the entangled portion is strongly rubbed with the cloth surface of the other portion or the inner peripheral surface of the drum, the cloth surface of the portion is rubbed. A thread 4 which remains as a trace of the streak state shown in FIG. Further, when the bent portion of the piece of cloth is strongly rubbed with the cloth surface of the other portion or the inner peripheral surface of the drum, a raw bend 5 is left on the cloth surface of the portion as a streak-like mark as shown in FIG. 6 (B). . The thread 4 is a piece of cloth 2 as shown.
The folds which are concavely dented from the surface of the cloth, and the raw folds 5 are ridges which are convexly bent from the surface of the cloth.

When the above-mentioned threads and raw breaks occur, these streaky marks do not easily disappear, so that the portion where these threads and raw breaks occur does not become a product and must be cut. .

The present invention has been made in view of the above-mentioned problems, and provides a washing apparatus in which a streak-like mark is not left on a piece of cloth and a raw breakage does not occur during washing processing in a rotary drum. It is an object.

[0008]

In order to achieve the above object, according to the present invention, in claim 1, a cloth and a washing liquid are introduced into the inside of a rotary drum which has a cylindrical shape and whose axis is horizontal. It is a device that rotates in a state to wash fabrics, and is provided with a separator made of a rod-shaped body that is inserted substantially parallel to the axis of the rotary drum between the fabrics that are set in a folded state inside the rotary drum. The present invention provides an apparatus for washing and processing fabrics.

The separator is formed by putting a hard rubber or a large number of spheres in a cylindrical shape in a long fiber bag to form a substantially cylindrical shape, imparting elasticity to enable deformation and restoration, and a required buoyancy. Have. (Claim 2) A resin ball or the like is preferably used as the sphere.
Also, the diameter of each separator is 5 for the inner diameter of the rotating drum.
% To 15%, and the length of the separator is preferably slightly shorter than the length in the axial direction inside the rotary drum in which the cloth is set, and is substantially the entire length. (Claim 3) Five to thirty separators are used and inserted substantially uniformly into the folded end portion of the piece of cloth to hold the folded state set during the spin washing process. (Claim 4)

Has an opening for inserting a piece of cloth and a door portion that opens and closes the opening in a part of the outer peripheral wall of the outer peripheral wall, and has an axial rib protruding from the inner surface of the outer peripheral wall, and the outer peripheral wall and the door. A large number of through holes for circulating the washing liquid are provided in the part. (Claim 5) The outer case may be a rotary type in which the outer case is rotationally driven and the inner case is rotated integrally with the outer case.

[0011]

In the washing apparatus according to the first aspect of the present invention, the washing machine is arranged inside the rotary drum in which the axis of the cylinder is arranged in the horizontal direction, sequentially from the lower end and from the position in contact with the front inner peripheral surface of the cylinder. The fabric is placed over the entire length in the front-rear direction up to the position where it comes into contact with the side inner peripheral surface, folded back at the front end and the rear end, and set so as to be folded up and down. At that time, insert a separator at the folded end. In this way, the piece of cloth that is folded back and set is fully arranged in the front-rear direction of the rotary drum, and is held by the separators on both sides of the folding end, so that the movement in the front-rear direction is restricted. Further, since the length of the separator is set to be slightly smaller than the total length of the rotary drum and the separator is arranged in parallel with the rotation axis of the drum, the lateral movement of the piece is also restricted. As a result, the piece of cloth is continuously folded and held in a folded state, and rotates in unison with the rotation of the rotating drum. No friction is caused by collision with, and it is possible to eliminate the scratches and straight breaks that have been generated conventionally.

According to the separator of the second aspect, elasticity is imparted so that the separator can be deformed and restored.
It does not damage the cloth by deforming with the cloth while rotating.
Moreover, because it restores to the original state, it suppresses the behavior of the cloth,
It is possible to return a piece of cloth to the set state. Further, since the required buoyancy is applied, it is possible to rotate the rotary drum integrally with the rotary drum without sinking the cloth in the lower portion.

When the diameter of each separator is 5% to 15% of the inner diameter of the rotary drum as described in claim 3, the separator does not take up a large space, and the piece can be regulated with a required force. . Moreover, if the length of the separator is made slightly shorter than the length in the axial direction of the inside of the rotary drum to make the length substantially the entire length, the behavior of the piece of cloth in the axial direction can be suppressed as described above.

As described in claim 4, the separator has 5 to 3 parts.
0 is used. The number to be used is selected according to the diameter of the separator and the kind of the fabric. In addition, it is preferable that the separator is inserted at the folded end of the cloth.
When the diameter of the rotary drum is large, it may be set in the intermediate portion between the front and rear ends as long as the uniform surface condition can be made to appear on the piece by the separator.

When the rotating drum is constituted as described in claim 5 and the washing liquid is filled from the outer case, the washing solution uniformly flows into the inner case through the washing solution through hole of the inner cylinder, and the inside of the inner case It is possible to uniformly wash the fabric with the washing liquid.
Hot water is preferably used as the washing liquid, and steam may be introduced when the temperature of the washing liquid is low.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show a state in which a long piece of fabric 2 is folded and inserted inside the rotary drum 10, and a separator 20 is set between the fabric 2. The rotary drum 10 has the same structure as the conventional one and is of a horizontal installation type. In this embodiment, the outer case 11 is a fixed type and the inner case 12 is a rotary type.

That is, the cylindrical outer case 11 is installed horizontally with the axis L as the horizontal direction, and the inner case 12 which is slightly smaller than the inner case 12 is rotatably provided with a required gap 13 inside the outer case 11. The support shaft of the inner cylinder 12 is attached to the outside of the outer cylinder 11 and is rotated by a rotation driving means (not shown) during the washing process. A supply pipe 14 for supplying hot water and cold water and a steam supply pipe 15 are connected to the outer case 11, and hot water, cold water, or steam is injected into the gap 13. Openings 11a and 12a for inserting / removing an article and the opening 11 are provided on the front sides of the outer body 11 and the inner body 12.
Doors 11b and 12b made of plates for opening and closing a and 12a are attached. Further, the inner peripheral wall of the inner case 12 is provided with ribs 12c protruding in the radial direction at a required interval in the circumferential direction. The ribs 12c are formed across both axial ends of the inner case 12. In addition, the peripheral wall of the inner case 12 including the door portion 12b is provided with through holes 12d for circulating the washing liquid over the entire surface at a required interval.

Through the opening 12a, one long piece of fabric 2 is continuously folded in the front-rear direction inside the inner case 12 and is set while being folded. As shown in FIG. 3, the separator 20 arranged at the folded end portion of the cloth 2 is formed of hard rubber into a columnar shape, and is given elasticity so that it can be deformed and restored and has buoyancy. .

The separator 20 has a diameter equal to that of the inner case 1.
The inner diameter of 2 is 5% to 15%, and the length thereof is slightly shorter than the axial length of the inner case 12. In this embodiment, the inner barrel 12 having an inner diameter of 100 cm
Using seven separators 20 with a diameter of 10 cm,
I set it with the cloth 2. That is, while inserting the separator 20 into the folded end portion of the piece of cloth 2, the piece of cloth 2 is set in the inner case 12 of the rotary drum through the opening 12a.
The set separator 20 is set over substantially the entire length of the inner case 12. Although seven separators are used in this embodiment, about 5 to 30 separators are used in consideration of the size of the rotary drum, the thickness of the cloth, the diameter of the separator, and the like.

As shown in FIGS. 1 and 2, after the cloth 2 is set inside the inner case 12 of the rotary drum 10 with the separator 20 interposed, the openings 12a and 11a of the inner case 12 and the outer case 11 are closed. Closed at 11b and 12b. Inner trunk 12
Although a large number of through holes 12d are formed in the
The outer case 11 is closed by closing the opening 11a of the door with the door 11b.
Is sealed. In this state, hot water having a required temperature is supplied from the supply pipe 14 connected to the outer case 11, and the washing liquid 3 made of hot water is introduced into the inner case through the through hole 12d of the inner case 12.

At this time, the required processing agent may be put into the washing liquid to carry out the washing process. In that case, the processing agent may be put inside the inner case 12 or the washing liquid side. It may be mixed in.

As described above, the inner barrel 12 is rotated while the washing liquid 3 is being put into the washing treatment. The inner barrel 12 may be continuously rotated in one direction, or may be rotated in both directions. By the rotation of the inner case 12, the piece of cloth 2 set inside the inner case 12 rotates, and at the time of the rotation, the washing process is performed by the washing liquid 3.

During the above washing process, the piece of cloth 2 is separated by the separator 20.
Both ends of the front-rear direction are pulled by the movement of the separator 20 to regulate the movement in the front-rear direction X, and
Since it is arranged in parallel with the rotation axis L of the above and over the entire length in the length direction, the movement of the piece 2 wound around these separators 20 in the length direction Y is also restricted. In this way, the cloth 2 is restrained from moving in the front-rear direction X and the length direction Y, so that the set state does not collapse even during rotation and is pulled by the separator 20 so that the surface does not have wrinkles. Retained.

Therefore, the twisting and entanglement of the fabric pieces, which occur when the rotary washing process is performed without using the conventional separator, and the contact friction between the fabric pieces, the inner periphery of the fabric body and the inner case 12 No contact friction occurs between the surface and the rib 12c. As a result, it is possible to eliminate or reduce the scratches and straight breaks that have conventionally been generated during the washing process of the cloth.

In the above embodiment, the separator 20 is molded from hard rubber, but as shown in FIG. 4, a large number of synthetic resin spheres (balls) 21 are sewn into a slender tube with a cloth made of nylon or the like. It is also preferable to fill the inside of the bag 22 to form the separator 20 '.

[0026]

As is apparent from the above description, in the device provided with the separator according to the first aspect of the present invention, the fabric that is folded back inside the rotary drum by the separator and is set in the longitudinal direction and the long length. Since the movement is suppressed in both the vertical direction, when it rotates together with the rotation of the rotating drum, it entangles, bends, breaks, collides with other parts and the inner peripheral surface of the drum, causing friction. It is possible to eliminate the scratches and straight breaks that have occurred in the past. Therefore, in the washed fabric, the portion that must be cut due to scratches or straight breaks can be eliminated or dramatically reduced, and the productivity can be improved.

When the separator according to claim 2 is used,
Since it can be deformed and restored by giving elasticity, it follows the movement of the cloth when it is about to deform during rotation so that it does not damage and damages it. By suppressing, it is possible to return the piece to the set state. Further, since the required buoyancy is applied, the piece of cloth is not sunk in the lower part of the rotary drum, the piece of cloth can be rotated integrally with the rotary drum, and the problem due to the installation of the separator can be eliminated. The above-mentioned separator has an extremely simple structure and can be obtained at low cost. Moreover, since it is not necessary to improve the rotating drum side, it can be easily implemented and has great practical value.

When the diameter of each separator is 5% to 15% of the inner diameter of the rotary drum, the separator does not take up a large space and the piece can be regulated with a required force. . Further, if the length of the separator is made slightly shorter than the length in the axial direction of the inside of the rotary drum to make the length substantially the entire length, as described above, the behavior of the piece of cloth in the axial direction can be suppressed. Further, as described in claim 4, about 5 to 30 separators are preferably used because of the correlation between the diameter of the separator and the diameter of the rotating drum. These separators are preferably inserted into the folded end of the piece of cloth, but when the diameter of the rotating drum is large, it may be set in the middle between the front and rear ends, and the separator allows the piece of cloth to be wrinkle-free and uniform. It suffices if the surface condition can be revealed.

The rotary drum according to the fifth aspect of the present invention is capable of efficiently washing cloth by combining it with a separator.
