Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chaffing machine and a chaffing method for giving a fluff to a woven or knitted cellulosic fabric made of purified cellulosic fibers.

[0002]

2. Description of the Related Art A woven or knitted cellulosic fabric made of purified cellulosic fibers made from wood pulp is first rubbed in warm water to make the surface fluffy, and then to be highly fluffed by an enzymatic (bio) process. Lowering and homogenizing, then bio-deactivation processing, washing,
It is used for products after undergoing flexible processing.

In the past, since there was no dedicated machine for the above-mentioned chaffing, a horizontally long outer cylinder and a horizontally long perforated inner cylinder (rotating drum) rotatably supported in the outer cylinder were for commercial use. Using a washing machine, warm water was poured into the cloth together with 5 to 6 pieces of dough, and the perforated inner cylinder was continuously rotated at a low speed to carry out the kneading process.

[0004]

However, in the conventional chaffing process using such a mere washing machine, the chaffing process is performed by inserting several fabrics into one perforated inner cylinder, and A stirring bar (projection body) attached to the inner wall of the body
Since it is originally used for washing, the number is small and the protruding height is low, so even if it is rotated at a low speed, the cloth does not slide enough on the inner peripheral surface of the drum and the rubbing action is not sufficient, or the rubbing is moderate. I found that even if the speed of the rotating drum was adjusted and set, the fabrics became entangled as they continued to rotate, and good buffing could not be applied uniformly to each fabric.

The present invention solves the problems of the prior art as described above, and is an epoch-making refined cellulosic fiber woven or knitted fabric capable of uniformly performing a very good buffing without excessively entangling the fabric. It is an object of the present invention to provide a fir-working machine and a fir-working method for the dough.

[0006] It is known that the idea of throwing the dough into the compartments partitioned by a perforated partition plate so that the doughs are not entangled with each other and the idea of rotating the rotating drum forward and backward (Japanese Patent Publication No. 51-34503). Issue No. 3-45995
No.) and the present invention, after studying and trial-and-error of such conventional buffing by drum rotation, perform a good buffing based on the utility model registration No. 3005922 by the applicant as a result of a trial experiment. The present invention has been completed by finding the constitutional conditions or processing steps that can prevent the fabrics from being excessively entangled with each other and can uniformly perform the buffing process on the respective fabrics.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of the present invention (how to carry out the invention) will be briefly described with reference to the drawings and showing its function and effect.

A woven or knitted cellulosic fabric 2 made of purified cellulose fibers is put into a rotatably supported rotary drum 1 together with a liquid agent such as warm water or a cleaning agent, and the rotary drum 1 is used.
When the cellulosic fabric 2 is subjected to buffing by rotating the dough, the dough 2 is placed in each of the plurality of small chambers 4 partitioned by the perforated partition plates 3 arranged at predetermined intervals in the rotary drum 1. The pieces are stored one by one and the rotary drum 1 is rotated.

By the rotation of the rotary drum 1, the dough 2 is locked by a plurality of projections 5 provided on the inner peripheral surface of each of the small chambers 4 at predetermined intervals, and the dough 2 is rotated with the rotation of the rotary drum 1. Is raised to a predetermined height and the protrusion 5 is caused by its own weight.
The fabric 2 is disengaged and dropped, and the dough 2 is also subjected to a buffing process.

However, according to the present invention, the dough 2 is raised and dropped at least by the protrusions 5 by the rotation control mechanism A for controlling the normal and reverse rotation of the rotary drum 1 rather than simply rotating the rotary drum 1. Possible 3 /
When the rotary drum 1 has been normally rotated by 4 rotations or more and less than 6 rotations, the rotation is temporarily stopped for at least several seconds, and the normal and reverse rotation operations of reverse rotation by the same rotation amount are repeated.

Since the cloth 2 is stored in each of the small chambers 4 partitioned by this, the cloths 2 are not entangled with each other, and the cloths 2 are not entangled excessively. Even if the rotation is excessively entangled, the excessive entanglement is eliminated by the reverse rotation having the same rotation amount as the normal rotation.

Therefore, by rotating the rotating drum 1 (by setting various conditions such as the drum size of each small chamber 4 with respect to the dough 2 to be charged in advance, the drum rotation speed, and the arrangement and size of the projections 5), The operation of the fabric 2 being locked by the protrusions 5 and being raised and falling to a predetermined height as the fabric 2 is rotated is repeated, and the fabric 2 is subjected to good chaffing, and the fabric 2 is excessively processed. Since they are not entangled with each other, the chaffing process is good and the treatment is even.

According to the second and third aspects of the present invention, the specific dimensional conditions are set so that the above-mentioned action and effect are exhibited extremely well.

[0019]

Embodiments of the present invention will be described with reference to the drawings. An outer case is provided on the frame 12, and a rotary drum 1 which is an inner case made of a punching plate supported by a main bearing 7 is rotatably provided in the outer case 6. The outer case 6 and the rotary drum 1 as the inner case are of a horizontally elongated inner cylinder shape as shown in the drawing. The outer case 6 and the rotary drum 1 are arranged concentrically, and the rotary drum 1 is arranged on the pedestal 6. Drive motor 8
Is configured to rotate the rotary shaft 10 via the transmission belt 9 and the like.

The rotary drum 1 is divided into a plurality of laterally adjacent small chambers 4 by a perforated partition plate 3 such as a punching plate, and a lid 11 for putting the dough 2 into each of the small chambers 4. Is attached so that it can be opened and closed.
The outer case 6 is also provided with an outer case lid that can be partially opened and closed, and an auxiliary material (liquid agent) feeding hopper or the like may be provided.

The inner diameter of each small chamber 4 is 140 to 180.
cm, width dimension 50-70 cm, 25-50 m, weight 1
The size of the rotary drum 1 and the interval between the perforated partition plates 3 are set so that the cloth 2 of 0 kg to 25 kg can be stored in each small chamber 4 one by one.

Further, 6 to 8 projections 5 are provided at equal intervals along the circumferential direction, and the projection height of each projection 5 is set to about 10% of the inner diameter of each small chamber 4. .

Specifically, for example, when a cellulose cloth 2 of 50 m, 20 kg is thrown into each small chamber 4, the inner diameter of each small chamber 4 is set to about 180 cm, the width is set to about 60 cm, and the projection 5 is formed. 8 will be arranged and the projecting height will be about 20 cm.

Further, for example, when a cellulosic fabric 2 of 10 m in length and 10 kg is put into each small chamber 4, the inner diameter of each small chamber 4 is set to about 140 cm, the width is set to about 50 cm, and the projections 5 are 6 pieces. It is arranged so that the protruding height is about 15 cm.

By setting in this way and adjusting to an appropriate rotation speed, the rotation of the rotary drum 1 causes the cloth 2 to be formed by a plurality of protrusions 5 provided at predetermined intervals on the inner peripheral surface of each of the small chambers 4. Is locked and the fabric 2 is raised to a predetermined height with the rotation of the rotary drum 1 and the protrusion 5 is caused by its own weight.
The fabric 2 is disengaged from the fabric and falls, so that the fabric 2 is subjected to a good chaffing process.

Further, in the present embodiment, a rotation control mechanism A for rotating the rotary drum 1 in forward and reverse directions is provided, and at least the protrusion 5 allows the cloth 2 to rise and fall 3/4.
The rotation control mechanism A is configured such that, once the rotary drum 1 has been rotated more than 6 rotations and less than 6 rotations, the rotation is temporarily stopped for at least several seconds or more, and the forward and reverse rotation operations of reverse rotation by the same rotation amount are repeated.

The rotation control mechanism A may be provided with a control device as shown in the figure, but a timer or a microcomputer control may be simply provided in the drive source, or the forward / reverse switch can be manually controlled. It may be configured.

Therefore, in this embodiment, the woven or knitted cellulosic fabric 2 made of purified cellulose fibers is rotatably supported on the rotary drum 1 by the porous partition plate 3 arranged at a predetermined interval in the rotary drum 1. Each piece of the dough is stored in each of the divided small chambers 4, hot water of about 30 times the volume of the dough 2 is supplied from the hot water inlet, and an auxiliary agent such as a cleaning agent is appropriately added. The rotary drum 1 is rotated. Due to the rotation of the rotary drum 1, the dough 2 is locked by a plurality of projections 5 provided on the inner peripheral surface of each of the small chambers 4 at predetermined intervals, and the dough 2 is kept at a predetermined height as the rotary drum 1 rotates. Then, the fabric 2 is lifted up and disengaged from the projection 5 by its own weight and falls, so that the material 2 is subjected to a good buffing process.

However, in the present embodiment, the dough 2 is lifted at least by the protrusions 5 by the rotation control mechanism A for controlling the rotation drum 1 in the forward and reverse directions, rather than simply rotating the rotation drum 1. Can fall 3
/ 4 rotation or more and less than 6 rotations (for example, only 2 rotations), once the rotary drum 1 has rotated normally, the rotation is once stopped for at least several seconds or more (for example, 5 to 15 seconds), and then the same rotation amount (only 2 rotations) is reversed. The rotating forward / reverse rotation operation is repeated.

Since the cloth 2 is stored in each of the small chambers 4 partitioned by this, the cloths 2 are not entangled (entangled) with each other, and the cloths 2 are not entangled excessively. Even if the entanglement is excessively entangled by the normal rotation, the entanglement (entanglement) is eliminated by the reverse rotation of the same rotation amount as the normal rotation.
Further, in particular, in the above-mentioned dimensions, the interval (width dimension) between the small chambers 4 is set to 50 to 70 cm, so that the put-in dough 2 is satisfactorily hitted and the problem of entanglement (entanglement) is further unlikely to occur. . That is, in the dimensional structure,
If the width is narrower than 50 cm, the fabric will be 25-50 m 2
Therefore, if it is wider than 70 cm, it will be too wide and entangled easily.

Further, since the rotation is temporarily stopped for a few seconds during the reverse rotation from the normal rotation, the entanglement is well resolved.

Therefore, by the rotation of the rotary drum 1, the cloth 2 is always locked by the protrusions 5 and the cloth 2 is raised to a predetermined height and dropped with the rotation.
The material 2 is satisfactorily rubbed, and even if such forward and reverse operations are repeated, it is not entangled excessively and is uniformly rubbed.

As described above, according to the present embodiment, as compared with the conventional method, the surface of the fabric is divided into fibrils due to the chaffing process and the enzyme solution treatment, and the powdery color becomes a three-dimensional color, and a pre-prepared instantaneous occurrence occurs. It has a firm and firm texture, and the texture of the surface is a unique ultra-soft texture, which makes it an unprecedented processed texture.

In the present embodiment, it is desirable that the small chambers 4 are arranged in parallel with each other in consideration of the processing efficiency and the mechanical strength. Specifically, in this embodiment, the number of the small chambers 4 is 6.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, it is possible to easily and in good condition provide a roughening process for a woven or knitted fabric made of purified cellulose fibers, which has been extremely difficult in the past. There is.

That is, according to the present invention, since the cloth is stored in each of the divided small chambers one by one, the cloths are not entangled with each other, and the rotating drum is not simply rotated. By the rotation control mechanism for controlling the forward and reverse rotations, at least the rotation drum 1 is normally rotated by at least 3/4 rotation or more and less than 6 rotations in which the dough can be raised and dropped by the projection body, and once the rotation is stopped for at least several seconds, Furthermore, since the forward and reverse rotation operations that rotate backward by the same amount of rotation are repeated, there is no excessive entanglement even in each fabric, and even if it is entangled excessively by the forward rotation, this entanglement is canceled by the reverse rotation. Become.

Therefore, by the rotation of the rotary drum, the dough is always locked by the projections, and the dough rises to a predetermined height and drops with the rotation, and the operation of repeating the dough is carried out. In addition, since the dough does not get entangled excessively, the chaffing process is good and it is uniformly applied. Be the way.

According to the second and third aspects of the present invention, the above-mentioned effects can be exerted extremely well, and a processed fabric having a very high commercial value, which is much better than the conventional example, can be obtained.
