DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on an embodiment shown in the drawings.

Reference numeral 1 denotes a cleaning tank, which has a cleaning cylinder 4 formed of an outer cylinder 2 and an inner cylinder 3 that is separated from the outer cylinder 2 and includes an inner cylinder 3. A water passage 5 is formed between the cylinder 3 and the outer cylinder 2. A large number of water holes 6 are formed on the entire surface of the inner cylinder 3, and a drainage port 7 is provided on the outer cylinder 2.

The cleaning cylinder 4 is fixed so that its cylinder axis a is vertical, and the upper opening 8 of the cleaning cylinder 4 is cleaned along the cylinder axis a. A wash water injection pipe 9 to be inserted into the cylinder 4 is located.

A cascade duct 10 for supplying a part of cleaning water into the cleaning cylinder 4 is provided at the periphery of the upper opening 8 of the cleaning cylinder 4.

A cloth outlet 11 for pulling out the rope-shaped cloth is provided below the washing cylinder 4. The inner diameter of the cloth outlet 11 allows the rope-like cloth to be drawn out. The diameter is as small as possible. Further, a radial packing 12 is laid in the middle of the fabric outlet 11 for suppressing the outflow of water in the cleaning tank 1.

Reference numeral 13 denotes a rope cloth guide tube which is provided inside the upper end of the wash water injection tube 9 at a concentric shaft position integrally with the wash water injection tube 9. The lower end opening is formed so as to be located between the inner surface of the cleaning cylinder 4 and the cleaning water jet pipe 9.

Water supply pipes 14 and 15 are provided at the upper end of the wash water injection pipe 9 and the upper end of the rope-shaped fabric guide pipe 13, respectively. Reference numeral 16 denotes a chain wheel provided outside the wash water injection pipe 9, and the chain wheel 16 is connected to a motor 18 capable of forward and reverse rotations via a chain 17. Reference numeral 19 is a bearing bearing that rotatably supports the wash water injection pipe 9, 20 is a rope-like cloth, and 21 is a water receiving tank installed below the cleaning tank 1.

The structure of this embodiment is as described above. Next, the operation thereof will be described. When operating the cleaning device, first, the pump 22 is driven to supply the water in the water receiving tank 21 to the water supply pipe 14. , 15, water supply, cascade duct 1
Overflow from 0 also toward the washing tank 1.

Then, the cloth 20 to be cleaned which has been transferred in a rope shape is dropped into the cleaning tank 1 through the inside of the rope cloth guide tube 13. At this time, when the motor 18 is rotated to rotate the wash water injection pipe 9 and the rope-shaped fabric guide pipe 13 at a low speed, the rope-shaped fabric 20 dropped from the rope-shaped fabric guide pipe 13 together with the wash water is washed with the washing cylinder 4. It descends in the washing cylinder 4 while being wound in a spiral direction with the washing water jet pipe 9.

The rope-like cloth passing through the rope-like cloth guide tube 13 receives the water flow from the water supply pipe 15 and is smoothly supplied into the washing cylinder 4. Next, the cloth 20 descending in the washing cylinder 4 in the spiral direction is subjected to the washing water overflowed from the cascade duct 10 and the water flow force of the washing water jetted from the washing water jet pipe 9 to progress the washing of the cloth. .

Since the normal rotation and the reverse rotation of the rope-like cloth guide tube 13 are alternately performed every 7 to 15 rotations, the rope-like cloth supplied into the washing cylinder 4 has
Twisting in the forward direction and the twisting in the reverse direction act alternately, whereby a rubbing force acts on the rope-like fabric, and an effective washing water displacement action is exerted to perform highly efficient washing.

In the thus washed rope-like cloth, the cloth drawing-out port 11 is drawn out of the washing tank 1. The diameter of the cloth drawing-out port 11 is an approximate value to the outer diameter of the rope-like cloth. Since the radial packing 12 is laid in the outlet 11, a large amount of washing water is not discharged from the fabric outlet 11.
Therefore, most of the amount of water supplied from the water supply pipes 14 and 15 and the amount of water overflowed from the cascade duct 10 are accumulated in the cleaning tank 1, and as a result, the contact between the accumulated water in the cleaning tank 1 and the rope-like cloth is increased. And the cleaning effect is enhanced.

In addition, a part of the water in the cleaning tank 1 has a water passage hole 6
Then, it is returned to the water receiving tank 21 through the running water channel 5 and the drainage port 7 and reused.

In this way, the rope-like fabrics that are successively supplied while being twisted in the spiral direction in the cleaning tank 1 are twisted in the forward direction or the reverse direction alternately in the cleaning tank 1, so that An effective kneading force intermittently acts on the rope-shaped cloth due to the twisting change action, and the replacement action of the wash water is enhanced.

Since the rope-like cloth supplied to the cleaning tank 1 is contacted with a large amount of water supplied to the cleaning tank 1, effective cleaning can be performed at the time of passing through the cleaning tank 1. Becomes

In FIG. 1, one set of cleaning devices is shown and explained. However, as shown in FIG. 3, if a plurality of sets of cleaning devices are provided and the same cleaning is repeated, a more complete cleaning is performed. Is possible.
