Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dyeing device. 4I The present invention relates to a jet type dyeing machine.

So-called jet dyeing machines for textiles have a transfer extension with a small cross-sectional area and a processing extension with a larger cross-sectional area and sitting either above or below the transfer extension. It has a housing defining a closed-circular path. This processing extension constitutes a processing section containing the dye bath. The fabric to be dyed is formed into a ring which is circulated within the housing by pumping the liquid dye solution up the housing. This is dye #! from the downstream end of the treatment area. This is accomplished by continuously withdrawing liquid and injecting it into the upstream end of the transfer extension or section, thus creating a circulating flow within the device. To aid in the movement of the dyed article, it is standard in many machines for the flooring of alpha-processing compartments to be sloped at the same time with its downstream end curve. Continuous agitation and mixing of the articles in such equipment provides a very uniform dyeing operation and substantially shortens the dyeing time.

does not function properly due to short baths.

Machines configured for use with long baths have processing chambers specifically designed to prevent knot formation in the articles being dyed.

If the depth of the chamber bath is reduced, the articles will not be held in enough liquid to move properly through the machine. Machines with short baths, on the other hand, are constructed to hold the articles in a minimal amount of liquid, and are unable to accommodate large amounts of liquid at all.

The impossibility of changing the volume of this bath is particularly troublesome in the case of small-unit processing or for chemicals used in high concentrations where short dye baths can be used, thus requiring a large and expensive solution with attendant placement problems. The so-called short baths, in which the ratio of the volume of the article to be dyed to the volume of the dye solution is between 1:1 and 1:1, have to make up a bath or rely on other equipment that does not dye effectively. It is impossible to use technology. Such techniques are desirable because they use very sparingly of expensive dyes or other chemicals, and because there is less liquid to dispose of when the operation is photonic.

Further, U.S. Pat. It is suggested that a means of companionship be established. Such action ensures that the dye is completely absorbed into the article. Even though the processing time is thus reduced, it is by no means possible to reduce the width of the bath as well.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an improved tomo dyeing apparatus.

The purpose of the pond is to provide a dyeing device which overcomes the above-mentioned disadvantages and which can be operated with shallow as well as deep baths depending on the processing requirements.

These purpose-row dyeing devices constitute a closed circular path with a transport extension of small cross-sectional area and a processing extension of larger cross-sectional area and branching perpendicularly from the transport extension. This is achieved by the present invention, which strengthens the housing. The treatment extension constitutes a treatment section containing the stain. Further means are provided for continuously withdrawing the dye solution from the F end of the processing section and injecting it into the upstream end of the progress section, so that the toroid of the article to be dyed contains the dye solution. is circulated within the housing. According to the invention, means comprising a bizette support the rounded housing in a pivoting movement about a horizontal axis and also move the housing between a lower long bath position and an upper short bath position. Means is provided for pivoting. In this way, it is possible to maintain the bath at any desired level regardless of its volume.

By virtue of the conditioning device of the invention, the bath can be typically the longest when the elongated treatment chamber is horizontal, and can be made very short by tilting the bath significantly. It is therefore possible to use the smallest bath size that can give the desired result, and thus the cost of chemicals as well as the costs associated with disposal problems are reduced to a minimum.

According to the invention, in situations where very long baths are required in the same device, l:4! It is possible to operate at a ratio of Moreover, with the same equipment.

The same process but different bath sizes can be used.

According to the invention, the means for pivoting can also include winches and cable mechanisms, including hydraulically operated jacks, either hydraulic or pneumatic.

In order to easily tilt the scissors, the pivot axis is generally located in the middle IL7. In such a device, the pivot axis #'iv
It can be placed at the end of the processing chamber, so that the device can be tilted in either direction from a central position intermediate between the long rest position and the short rest position.

It is also possible for this device i1 to have one end where the - is placed and the opposite end where the pivoting means are placed.

Such a mechanism can be easily installed as part of conventional equipment.

The above-mentioned and other advantages will become readily apparent from the following description with reference to the accompanying drawings.

As shown in Figure 1, 41! A comparable prior art machine includes a transfer tube-2, a processing chamber-3. Means for circulating the bathing liquid throughout the treatment bath and the bathing area
has. The floor of processing section J is sloped. In FIG. 2, the prior art machine/a has its transfer tube 21 and pump ta above the processing section 31, and can have λ different bath depths L and L'. In Figures 1 and 2, dye #! The liquid barrel and feed system are not shown, nor is the fabric loop and the roller feed for loading and unloading it into the device.

According to the invention as shown in FIGS. 3 and 1, the jet device @ib has a transfer tube 2b as shown in FIG. 1 above the processing compartment 71) containing bath +b. However, here the entire apparatus lb is a horizontal peat jb
01 and can be raised and lowered around this pit jb by means of a hydraulic shirt jb at the opposite end of the companion device lb. When tilted downward as shown in FIG. 3, this machine operates with a so-called long bath. When tilted upwards as shown in Figure 1, the device has a short bath.

The dimensions of the bath can vary between these two levels with no floor space.

Jet device t/c in figure 1 and ag4 is oats 9-7
It is a 0-type and has an injection tube λC and a nose socket 7C. Here, the jack 4C for pivoting the entire assembly around the bit jc is actuated by pneumatic pressure. The 56-podium section 3C therefore has a long bath #C as shown in FIG. 7F and a short bath as shown in FIG.

The apparatus of FIGS. 7 and 1 is also of the oat 9-flow type and has essentially the same construction as shown in FIGS. d is added. In this device, the pit jd is very close to the center of mass of the device i4.

Other injection-type machines with nozzle sockets 7et- are shown in FIGS. 2 and 70, and corresponding reference numerals are used.

Figures 1/1 and 1 λ show the machine of figure m/ to which the device of the invention is applied, in which reference numerals corresponding to X4 with the letter f are used.

In the Mk bond, Figures 1J and 1 are the upper V-shaped processing chamber Jf containing the downward circulation or transfer tube t1 and the bath a1.
, and a central pin 2) jf. The winch device It allows the machine to be tilted between the long rest position of FIG. 13 and the short rest position shown in FIG.

The device according to the invention therefore makes it possible to maintain the bath level at any desired height virtually independent of the bath volume.

The volume of the bath can thus be adjusted precisely depending on the process being carried out and the amount of items being processed, rather than depending on the dimensions of the apparatus as in prior art apparatus.
