Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for automatic cleaning and changing dye liquid in a dyeing padder, and more specifically, to a method and apparatus for automatically cleaning and changing dye liquid in a dyeing padder. The present invention relates to automatic cleaning and dye solution changing means for dyeing padders that can be significantly shortened compared to conventional padders.

B. Prior Art Dyeing pangu is used for the purpose of dyeing continuously supplied fabrics. In the dyeing process using such a dyeing padder, conventionally it was common to dye a large loft of 10,000 meters for one color, but recently it has become possible to produce a large variety of products in small lots. Therefore, the size of the dyeing lot is often set to about 500 to 1000 meters. The moving speed of the fabric in the dyeing padder is approximately 60 to 100 meters/min (7 degrees), so if the dyeing loft is set to 600 meters per color, the dyeing time is only 6 to 100 meters/min (7 degrees). It only takes 10 minutes.On the other hand, after finishing processing for one dye loft, the padder's dye bath is cleaned and new dye bath for the subsequent dye loft is supplied into the washed dye bath. It takes about 10 to 15 minutes to apply electricity.In other words, the preparatory time is almost twice as long as the dyeing operation time, and the efficiency of the pasoding process is significantly impaired. However, some technical proposals have been made to solve the problems associated with such conventional padders.For example, in the Senkeizai Shimbun published on January 1, 1980, Approximately 3 times the guiding cloth connecting between the two passes through
The bung is designed to automatically perform dye preparation work such as cleaning the padder body and the inside of the dye tank, supplying new dye solution, and cleaning the guide rollers of the dryer within minutes. has been done. This padder is composed of a two-stage reversible dye bath lifting device, a solenoid valve for switching between liquid supply and washing, and a micropro sensor, etc., and the dye bath is controlled separately during dyeing, supply and drainage, and washing. Configured to occupy different operating positions. By submerging such an operating position exchange mechanism in the dye vat (one immersion), the preparation time for the bangu was considerably shortened compared to the conventional bhang. Because of the method used, it was not possible to overlap the cleaning time and the time for supplying a new dye solution, and it was virtually impossible to shorten the preparation time to 3 minutes or less.

8. OBJECTS OF THE INVENTION The main object of the present invention is to provide automatic cleaning and dye solution changing means for a dyeing padder, which greatly reduces the time required for dyeing preparation work.

The automatic control device includes switching of the switching valves (20), (24) and dye liquor switching valves (27), (28), and horizontal movement and vertical movement of the dye liquor tanks (2), (2°). It is possible to incorporate an automatic control device such as a micro-prosensor as a means for regulating the timing, and in order to continuously perform pad dyeing on multiple dyeing lots according to a dyeing program set in advance, the automatic control device It is also possible to connect to the device a seam detection sensor (not shown) that detects the seam between the fabric (3) and the guide cloth.

Hereinafter, the method of the present invention will be explained in detail with reference to the attached FIGS. 2 to 5. First, in the state shown in Figure 2, panda (1
) The fabric (3) introduced into the guide roll (17
) is suspended in the dyeing position (D) by a dye bath (2).
), and after being immersed in the dye liquor injected into the dye liquor tank (2), it is guided by the subsequent guide roll (17) to pass through the dyeing roll (15), (15'
), excess dye liquor is removed, and the dye is being supplied to a subsequent process (not shown) such as a drying process. At this time, the second dye liquor tank (2'') located at the second preparation liquid supply position (P2) below the dye liquor tank (2) receives washing water supplied from the washing water supply pipe (5). After that, a pre-selected dye solution is being supplied into the dye bath via the dye solution supply pipe (4) according to the dyeing program.
At this time, the dye liquid tank (2) is placed at the first preparation liquid supply position (Pl).
is not present, the dye liquid supply pipe (4) provided at this preparation liquid supply position (Pl) is blocked from the pipe line to the dye liquid tank (23) by the switching valve (28). During this time, the interior of the dye liquor supply pipe (4) completes washing with washing water and air purge with a compressed air flow by switching the changeover valves (2o) and (24), and prepares for the next supply of new dye liquor. On the other hand, the first dye liquid 41 (2) is suspended and supported at the dyeing position (D).
The dye liquid from the operating liquid supply pipe (6) flows into the interior through the receiving plate (25), and maintains a substantially constant dye liquid level regulated by the liquid level control valve (21). While maintaining the fabric (3
) is impregnated with dye.

- When the band dyeing for the dye lot of F is completed, the supply of the dye liquid from the operating liquid supply pipe (6) is shut off by operating the switching valve (27) of the selected dye liquid tank (23). and the operating liquid supply pipe (6) is connected to the switching valve (2o), (
24). In this state, the dye liquor tank (2) is lowered onto the dye liquor tank support plate (9) by activation of the lifting means (E) as shown in Fig. 3, and the washing water supply pipe ( 26) and the cleaning water supplied from the operating liquid supply pipe (6) to perform primary cleaning.

That is, selectively opening and closing the wash water switching valve (24),
A plurality of water fountains (
18) to the part contaminated with dye liquor (front guide roll), and at the same time, the operating liquid supply pipe (6)
Washing water is also spouted from the receiving plate (25) and the dye tank (2).
), etc. After cleaning is completed, the cleaning water switching valve (24) is closed, the corresponding compressed air flow switching valve (20) is selectively opened, and the operating liquid supply pipe (6) and the cleaning water supply pipe (2) are closed.
6) Perform air purge. In addition, in the above-mentioned - next washing, in order to hasten the discharge of the used dye solution, the first dye '/&
Preferably, the drain valve (23) is opened at the same time as the vat (2) begins to lower onto the vat support plate (9). In addition, in order to minimize cleaning time, the pad dyeing for one dyeing loft is completed at the same time.
That is, it is desirable to start cleaning immediately before the first dye bath (2) starts to descend from the dyeing position (D) toward the dye bath support plate (9). It is preferable to intermittently repeat cleaning and air purging of the inside of the liquid supply pipe (6) multiple times to more completely clean the inside of the pipe. This repeated washing is carried out to prevent the next new dye liquor from becoming even slightly contaminated by residual dye liquor from the previous one. Also, preferred embodiments of the present invention! As an embodiment, the padding rolls (15), (15' By washing and simultaneously feeding a wet guide cloth, it is also possible to wipe off the dye that has adhered to the guide roll or the like in a subsequent process, for example, a drying process.

When the second washing is completed, the horizontal moving means (HT) is started to move the dye bath support plate (HT) as shown in Fig. 4.
9) Move the first dye bath (2) supported above to the dyeing position (D
) from the lower lowering position (P3) to the first preparatory liquid supply position (
At the same time, move the second dyeing tank (2°) into which new dye solution is injected to the second preparatory solution supply position (Pl).
z) to a raised position below the staining position (D) (same position as the lowered position (P8)). The second dye bath (which has been moved to the raised position (P8) in this way)
2) is then lifted to the dyeing position (D) using the upward stroke of the lifting means (E) as shown in Fig. 5, and the fabric (3) is introduced into the nucleus. , restart the dyeing process according to the same procedure as above.

While the pad dyeing according to a new dyeing program is progressing with the dye liquor in the second dye liquor tank (2°), the first dye is transferred to the first preparatory liquor supply position (Pl). Liquid tank (2)
In this step, the same secondary cleaning and injection of new dye solution as at the second preparatory liquid supply level 1t (Pz) are performed. That is, the dye bath (2) is filled with wash water supplied from the wash water supply pipe (5) provided at the first preparation liquid supply position (Pl).
After the secondary cleaning of the dye liquid and the air purge in the pipe by compressed air flow are completed, a new dye liquid is supplied from the dye liquid supply pipe (4) into the dye liquid [(2), Return to the staining position (D) and complete the preparation operations. On the other hand, during this period, the dye liquor supply pipe (4), which has finished supplying the dye liquor at the second preparatory supply level Fl (Pz), continues to supply the preparatory liquor while the dye liquor tank (2') is absent. Cleaning and air purging are performed in the same manner as in liquid position (P+) in preparation for execution of the next dyeing program.

As can be understood from the above explanation, the two dye baths (2) are moved using the elevating means (E) and the horizontal moving means (HT).
, (2°) between the dyeing position (D) and the first and second preparation liquid supply positions (Pl), (Pz), the fabric (3) is moved into one dye bath ( For example, dye bath (2
))), the other dye solution i (for example, dye solution PI < 2°)) at the preparation solution supply position is subjected to secondary cleaning and injection of a new dye solution. It can be tightened.

In carrying out the present invention, the cover plate (19) is
This prevents foaming of the dye liquor at the introduction of the fabric into the dye liquor tank (2), (2゛), and prevents droplets scattered on the fabric (3) before being dyed. The canopy (14) functions as a fabric protection member to prevent staining from occurring, and the canopy (14) is located at the preparation liquid supply position (Pt) or (
Dye liquor protection to prevent washing water or dye liquor used in a previous dye lot from dripping into the dye liquor tank (2) or (2°) in P2) and causing contamination of the new dye liquor. It functions as a military unit.

E9 Effects of the Invention As is clear from the above explanation, according to the method of the present invention, part of the cleaning time of the dye bath and the injection time of new dye solution can be made to overlap with the fabric dyeing operation time. Preparation time can be reduced to about 1 to 2 minutes per 10 tons. Accordingly, by connecting the fabrics to be dyed with a guide cloth of an appropriate length, the fabrics can be continuously run without stopping the operation of the entire process. Moreover, the length of the guide cloth required in this case is sufficient for running for 1 to 2 minutes, so that the loss of the guide cloth can be reduced. Therefore, the productivity of the banding process can be maintained at a good level even in the recent dyeing process of a wide variety of products in small lots.

Furthermore, since the device of the present invention has a simple structure in which a means for raising and lowering the dye bath and a means for horizontally moving it are attached to the main body of the bung, there is no risk of a significant increase in the manufacturing cost of the padder. Its wandering efficiency can also be maintained at an extremely high level.
