Each recovery section 27 is connected to the processing liquid tank 19 by a recovery pipe 28, and the separated processing liquid is returned into the processing liquid tank 19 via the recovery pipe 28. . As shown in FIGS. 1 to 3, in the embodiment, the recovery pipe 28 has one end connected to the bottom of the recovery unit 27 and the other end opened above the processing liquid tank 19, so that the processing liquid is processed. It is configured to return to the inside of the tank 19.

The above-mentioned divided pipe 16, processing liquid jetting section 24,
Treatment liquid tank 19, supply pipe 25, pump 26, recovery unit 27,
One processing unit 29 is constituted by the collection pipe 28 and the like. Then, the plurality of processing units 29 are connected along the flow of the cloth 13, and the cloth input section 14 is provided at the entrance end of the processing unit 29 arranged at the most upstream side, and the processing unit 29 of the most downstream side is arranged. A processing apparatus is configured by installing a fabric discharge pipe 17, a recovery tank 18, and the like at the outlet end.

Next, the operation of the processing apparatus will be described. Now, as shown in FIG.
When performing the pre-dyeing or post-dyeing treatment on the cloth 3, first, the cloth 13 is inserted into the processing unit 29 located at the most upstream side of the processing apparatus by the roller 15 while keeping its shape in the form of a rope. Next, in the processing unit 29, the processing liquid stored in the processing liquid tank 19 is injected from the processing liquid injection unit 24 into the divided pipe 16 in the outlet end direction. Then
The cloth 13 is transferred to the collection unit 27 through the split pipe 16 in a state of being suspended in the processing liquid by the jetting force of the processing liquid.

When the processing liquid and the cloth 13 transported to the collecting section 27 pass through the collecting section 27, the cloth 13 passes through the inner cylinder 27b as it is and the processing liquid passes through the liquid holes 27c. To some extent. The cloth 13 separated from the processing liquid still maintains its momentum, and is inserted into the next processing unit 29 located downstream of the processing unit 29 as it is. At the inlet end of the next processing unit 29, the processing liquid is again jetted from the processing liquid jetting unit 24 to the cloth 13, and the cloth 13 is urged toward the outlet end.

By repeating the above operation, the cloth 1
3 continuously proceeds in each processing unit 29 to the outlet end of the transfer pipe 12. At this time, each processing unit 2 on the upstream side
In 9, a processing liquid in which a processing agent is mixed is sprayed on the fabric 13 to perform pre-dyeing or post-dyeing processing, and only water is injected in each downstream processing unit 29 to wash out the processing liquid, Washing of the fabric 13 is performed. And
The cloth 13 discharged from the cloth discharge pipe 17 is immersed in water in the collection tank 18 and finally washed, whereby the pre-dyeing or post-dyeing treatment is completed.

In the process of processing the cloth 13, the processing liquid is separated from the cloth 13 in the recovery section 27, collected in the processing liquid tank 19, and then supplied to the processing liquid jetting section 24. It is circulated in the processing unit 29. Between each of the processing units 29, the water discharged from the recovery tank 18 is supplied to the processing liquid tank 19 disposed at the most downstream side through the communication pipe 20, and the processing liquid tank 19 on the downstream side is started. Are sequentially supplied to the processing solution tank 19 on the upstream side. Then, the processing liquid collected in the processing liquid tank 19 arranged at the most upstream side is discharged as it is without being supplied to the other processing liquid tanks 19 except for the part supplied to the processing liquid jetting unit 24.

Therefore, the processing liquid is reused not only in each processing unit 29 but also between the processing units 29, and the amount of the processing liquid used is reduced. Furthermore, by supplying the processing liquid in the processing liquid tank 19 on the downstream side to the processing liquid tank 19 on the upstream side, a processing liquid with higher freshness is supplied into each processing liquid tank 19, and the processing unit 29 Cloth 1
3 is maintained.

The effects exerted by the above embodiment will be described below. -The cloth 13 to be subjected to the pre-dyeing or post-dyeing treatment can be treated in the form of a rope without spreading, thereby simplifying the work and shortening the work time.

In the process in which the cloth 13 travels from the inlet end to the outlet end of the transfer pipe 12 in the apparatus, a series of operations from processing with the processing liquid to washing off of the processing liquid by washing are performed continuously, so that the working time Can be further reduced.

The recovery unit 2 provided downstream of the processing liquid injection unit 24 with the processing liquid injected from the processing liquid injection unit 24
7, the amount of processing solution used can be reduced.

The processing liquid tank 19 of each processing unit 29 is connected by a communication pipe 20, and a processing liquid with high freshness on the downstream side is supplied to the processing liquid tank 19 on the upstream side, whereby each processing unit 2
9 can maintain the processing ability for the fabric 13.

The cloth 13 is transported in the apparatus in a state of being suspended in the processing liquid by the jetting force of the processing liquid.
No extra force is applied to No. 3, stretching, wrinkling, split pipe 1
6 can be prevented from rubbing against the inner peripheral wall, and can be transported smoothly in a stable state.

By arranging the transfer pipe 12 in a spiral shape, the installation space can be saved and the size of the apparatus can be reduced.・ By supplying the processing liquid collected on the downstream side to the upstream side and reusing the processing liquid, it is possible to save water, a processing agent, etc., and to use a pump or the like for each processing liquid tank 19. There is no need to provide a processing liquid supply facility, and it is possible to save energy used in the entire apparatus such as electricity.

Regardless of the width, the cloth 13 is rolled and processed in a rope shape, and is transferred in a state of being suspended in the processing liquid. Also, since it is not necessary to have a predetermined length for taking out of the apparatus, a small lot of cloth 1
Even with 3, the processing can be performed in a short time.

For example, washing after dyeing can be performed by supplying water, hot water or the like into the dyeing apparatus, but in this case, the operating rate of the dyeing apparatus decreases and the dyeing process is repeated. In this case, the dyeing solution must be exchanged with water, hot water or the like, and the working efficiency decreases. The processing apparatus of the embodiment can wash the rope-shaped cloth 13 taken out of the dyeing apparatus in a short time without any modification, and can use the dyeing apparatus only for the dyeing process. The operation rate and work efficiency can be improved.

The present embodiment can be embodied with the following modifications. As shown in FIG. 5, if only the fabric 13 is washed with water, the number of connected processing units 29 in the apparatus is reduced, and the stirring device 22 and the heating device 23 provided in the processing liquid tank 19 of each processing unit 29 are used. May be omitted.

As described above, by limiting the processing purpose to washing with water, the processing apparatus can be reduced in size and simplified in configuration. It is not always necessary to connect the recovery tank 18 and the most downstream processing liquid tank 19 with the communication pipe 20. For example, only the respective processing liquid tanks 19 are sequentially connected with the communication pipe 20 from the downstream side to the upstream side. Alternatively, water may always be supplied to the processing liquid tank 19 on the most downstream side.

Even in such a case, it is possible to reuse the processing liquid and to maintain the processing ability. It is not necessary that the heating device 23 keeps all the processing liquid tanks 19 at the same temperature. For example, in the case of the scouring treatment, the temperature of the processing liquid is adjusted so as to increase in order from the upstream side to the downstream side. Is also good.

By adjusting the temperature of the heating device 23 as described above, the temperature of the processing liquid can be finely adjusted according to the processing purpose. The recovery unit 27 does not necessarily need to be provided one by one in each of the divided pipes 16. If the recovery unit 27 is disposed downstream of the processing liquid injection unit 24, for example, the recovery unit 27 may be provided in the processing unit 29 disposed most downstream. One may be provided, or one may be provided in the processing unit 29 disposed at the center of the apparatus.

With such a configuration, the configuration of the apparatus can be simplified. The treatment liquid tank 19 may be omitted, and the treatment liquid injection unit 24 and the collection unit 27 may be directly connected by the collection pipe 28. in this case,
Preferably, the pump 26 is connected to a collection tube 28.

With this configuration, the configuration of the apparatus can be simplified. The transfer tube 12 of the embodiment is formed in a square annular shape when viewed from the plane by combining the U-shaped split tube 16 in the plane, but is not necessarily limited to this shape. By changing the shape of the split tube 16, for example, a polygonal ring such as a hexagonal ring or an octagonal ring, an annular ring, or the like may be used.

As described above, since the processing apparatus is constituted by a combination of the plurality of processing units 29, the layout and shape thereof can be easily changed even when the processing apparatus is to be installed in a space. .
