Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to a device for fixing dyeing bobbins according to the preamble of claim 1.

The invention also relates to the use of the device in dyeing and bleaching processes according to the preamble of claim 12.

In dyeing and bleaching devices, the yarn bobbin windings to be dyed or bleached are carried on material carriers. In order to improve the flow of the processing liquid in this bobbin, the bobbin is attached to a bundle (8chvert) or a perforated tube, and there is a gap between the base plate provided at the lower end of the bundle or tube and the fixture provided at the upper end. is fixed.

The known substrates and fixtures have the disadvantage that the bath liquid, which is introduced under pressure via the bundle or tube, does not flow through the bobbin, but instead flows out of the ends of the bobbin tube.

Losses due to this leakage are particularly large in extremely tight pancages, which are common in precision winding.

The object of the invention is to create a device which eliminates the drawbacks of the known devices and which ensures a reliable seal at the end of the tube of the dyeing bobbin.

Furthermore, an object of the present invention is to fix the tube to the dyeing tube body so that the tube can be directly transferred to the next processing step without having to be rewound again after dyeing.

These objects are achieved according to the invention by the features of patent claim 1.

According to the invention, a cap body is attached to the end of the bundle or the tube body and between the tubes, especially between the perforated tube and the non-perforated tube, thereby preventing the outflow of the bath liquid and accompanying this. An unobjectionable flow through of the dye is advantageously achieved.

Due to the fact that the end faces of the bobbins are spaced apart from each other, entanglement of the threads at one end face of the bobbin is completely avoided, since between these bobbins the bath liquid no longer directly flows out of the tube end. The bath liquid can flow unimpeded on the bobbin ends as well as on the circumferential surface of the bobbin, thereby ensuring uniform dyeing.

Advantageous further embodiments of the invention are described in claims 2 to 11.

By providing an annular groove or notch in the cap, precise positioning of the cap on the tube end is achieved. The deep notch formed in the lower cap is
Good sealing is ensured even if the bobbin lifts up somewhat from the substrate in the tube due to overpressure. By using a thin-walled collar with a diameter smaller than the diameter of the tube, surface pressure contact of the cap with the substrate is achieved and lifting of the cap is prevented when the pressure of the bath liquid in the tube increases.

In the following, the invention will be explained in more detail with reference to the exemplary embodiments illustrated in the accompanying drawings.

FIG. 1 shows the parts of the material carrier 1 that are essential for understanding the invention. A number of staining tubes 3 are screwed or mounted around the substrate 2 of the material carrier. A substrate 4 is provided at the lower end of a conventionally known dyeing tube 3 (which may also be a dyeing balladle), and a bobbin 5 to be inserted into the dyeing tube 3 is placed on this substrate. A fixing tool 6 is detachably attached to the upper end of the dyeing tube body B. The bath liquid is introduced through the substrate 2 into a dye tube 6 which is perforated in a known manner.

Caps 7 and 8 are installed between the substrate 4 and the bobbin 5 and between the fixture 6 and the bobbin 5. These caps 7 and 8 do not touch the end faces 9 and 10 of the bobbin 5.

Therefore, the bobbin 5 is placed above the caps 7 and 8 on the tube 1.
The end portion 11 of 3 is only in contact with +2.

The upper part of the cap 8 shown in FIG. 2 has a rotating collar 13 formed on its underside, into the center of which the end 11 of the tube 13 can be inserted. A collar 23 is likewise formed on the upper side of the cap 8 , which aligns the tube 13 with respect to the fixture 6 . The collar 13 is offset somewhat inwardly with respect to the curve of the cap 8. Therefore, the conventional star (s
ter) or a stepped portion 16 for attaching the cover 17.
is formed. The cap 7, which is shown below in Figure 3, is provided on its upper side, ie on the side facing the end of the tube 12, with a notch 18, which is secured by a collar 13 (see Figure 2). Cut 1 to be formed
It has a depth greater than 4. On the underside of the cap 7, a cylindrical thin-walled collar 20 rests on the curve of the central opening 19, the end 21 of this collar resting on the base plate 4.

The diameter of the collar 20 is kept as small as the diameter of the dye tube 5 allows. The circumferential surface of the cap 7 is formed with a step 16 in the same manner as in the cap 8 for accommodating a star 17 of conventional construction.

FIG. 4 shows the construction of an upper cap 24, which is used if there are not enough bobbins 5 to completely fill the material carrier 1. In this case, a blind tube 22, ie a tube without holes, is inserted above the cap 24.

The lower surface of the cap 24 is formed similarly to the structure of the lower surface of the cap 7, and therefore the structure of the lower surface will not be described in detail here.

A notch 26 is formed on the upper side of the cap 24 for accommodating the lower end of the blind tube 22. This notch 26, like the notch 18 in the cap 7, has a slight play with respect to the tube in order to achieve a good seal. Instead of the annular notch 26 on the upper surface of the cap 24, it is also possible to form an annular step (not shown) through which the blind tube 22 is attached.

The ends 11, 12 of the tube 13 are advantageously formed in such a way that they fit into each other, so that a tight connection is achieved here as well. The tube 13.22 shown in FIGS. 2 to 4 has a notch 2 at the bottom.
8 on the inside, the diameter d is almost equal at the top - notch 2
9 on the outside.

An additional 0-IJ ring 30 is additionally embedded in the notch 29 to provide a good seal between the ends of the tube 13.22.

It is also possible to form the lower cap 7 as part of the substrate 4, or the substrate 4 may be provided with the upper structure of the cap 7 (see FIG. 6). This construction of the invention is used in particular when an existing material carrier 1 is not at hand, but when the puddle or staining tube 3 is equipped from the beginning with a cap according to the invention.

When the bobbin 5 is attached to the dyeing tube body 3, the lower end surface 9 is located at a slight distance e from the star 17, and the upper end surface 9 is also located at a distance from the end surface 9 of the bobbin 5 located above. f (see Figures 5 and 6).

The lower end 12 of the tube 13 is connected to the notch 18 in the cap 7.
exists within. The upper end 11 is located in the notch 14 of the cap 8 when the staining tube 6 is fully activated (see FIG. 5) or when an upper blind tube 22 is required. This upper end 11 lies within the cutout 14 of the cap 24 (see FIG. 6). If the blind tube 22 is installed, it is closed on the upper side with a cap 7 and is likewise pressed against the base plate 4 with a fixture 6.

The sealing between the tube end and the substrate 4 or between the tube end and the baradole or fixture 6 of the dyeing tube body 3 is achieved primarily in the manner of a precise press-fit and only slightly by the elasticity of the cap 7.8. Instead of caps 7 and 8,
It is also possible to insert an elastic sealing cap 31, 32 into the conventionally used dish or star 35 (see FIG. 7.8.9).

Patsukin cap 51. Advantageously, '52 is made of heat-resistant and chemical-resistant rubber. These packing caps form a positive seal between the end of the tube 13 and the substrate or fixture 6, and pass through the central hole 34 of the conventional dish 33. The packing cap 31 (FIG. 7) rests loosely on the dish-shaped part 33, and has a conical part 35 passing through the opening of the dish-shaped part 35 and an annular part that rests on the dish-shaped part 53. The tube 1 consists of a section 36 and a
It has a groove 57 formed around the periphery as a guide portion of 3. A sealing cap 52 (FIG. a) is secured in the opening 34, on the one hand (on the lower side) to accommodate the tube end, and on the other hand (on the upper side) to seal the substrate 4 and the fixture 6. It is provided with shoulders 4o, 42 shaped as surfaces. The completely conical packing cap 52 is provided on the outside with a circumferentially formed notch 38 into which the edge of the opening of the dish 36 engages.

In the ninth case, the cap 39 is designed as a sealing element and a dish and is additionally provided with a sealing cap 61, as shown in FIG. This results in
Precise sealing is achieved both for the fixture 6 and for the substrate 1.

As a sealing element for the tube 16, an O-ring 40 is provided in the collar-like extensions 41, 42 which abut against the surface of the tube. The dimensions of these extensions A1, 42 are determined by the pressure of the bath liquid within the tube 13.
The tube 1S is set so that it always remains in contact with the O-ring even when the tube 1S is slightly lifted.

When the material carrier 1 is loaded with bobbins and inserted into the autoclave, the bath liquid is forced into the dyeing tube s in a known manner. Since the tubes 11, 12 are engaged with each other, no significant leakage of bath fluid occurs at the joint location of these tubes. The same goes for tube 13 or 2
The same can be said about the bonding position of 2.

Extremely strong surface pressure contact occurs between the thin collar 25 of the cap 8 or the collar 20 of the cap 7 and the fixture 6 or the substrate 4. Why .

This is because both the collars 20 and 25 have a small diameter, and the contact area of these collars is correspondingly small.

Instead of an elastic slight cap 7.8 as a connecting element between the collar 13.22 and the fixture 6 or the substrate 4,
Cap 51.52 made of soft material such as rubber
When using a large-sized sealing surface, sealing is performed.

From experience, the bobbin 5 attached to the dyeing tube body 3 is lifted up somewhat by the pressure of the bath liquid. That is, the lower end portion 12 of the bobbin 5 located at the bottom is lifted up from the cap 7 or the dish-shaped portion 39. However, since the notch 18 is deep, the guide and tube IS are always connected to the cap 7 or the dish-shaped s59.
A seal between the two is maintained.
