Description

Dyeing device for hat stumps and other things floating freely in the fleet Textile piece goods One already knows dyeing devices for hat stumps and other things in of the liquor free-floating piece of textile goods, in which the dye liquor alternates sucking and pressing through a dye container with a bottom sieve and then Mixing room is moved. By this arrangement and movement of the dye liquor in reversible Cycle is to be achieved that the color piece (hat stump) with each reversal of the circuit is relocated without mechanical aids. This rearrangement can However, without mechanical aids only imperfectly take place because the perforation of the sieve bottom and that of the side sieve wall meet at a right angle. When passing through the dye container, the dye liquor naturally prefers the places where there is the least resistance, and there those between the sieve surfaces lying layer height of the work material at the colliding edges of these sieve surfaces approximately equal to zero, but at least equal at the opposite ends the filling level, most of the dye liquor passes through the one closest to it adjacent holes of the two sieve surfaces without any particular effect to be able to exercise on the remaining parts of the paint. The rearrangement of the color material therefore takes place in an imperfect way, or it must be carried out by a special stirring tool be supported, which can easily damage the material to be dyed due to pressure points, Color breaks or cracks.

The object of the invention is a dyeing device for hat stumps and other piece of textile goods floating freely in the fleet, which belong to the aforementioned Belongs to the genus of dyeing machines. In order to use such devices where the Dye liquor through a dye container with bottom sieve and subsequent mixing room is moved in a reversible cycle, with regard to the rearrangement of the colored pieces A whisking loosens and whirls through the entire filling without mechanical aids Achieving the effect of the dye liquor flow in both running directions is according to the invention the full-walled partition separating the mixing space from the paint container at its upper end provided with an overflow strainer to achieve a waterfall-like flooding of the material to be dyed in the dye container during the suction period, i.e. during the The liquor movement is from top to bottom, and still is opposite to the mixing chamber Side wall of the tub for guiding the upward through during the printing period the dyeing liquor moved obliquely outwards upwards. By doing the dye liquor overflowing from the mixing room to the working room in the dyeing tank from above in the suction period on the work material fall down leaves, there is a lively, overturning movement of the floating piece of textile, especially the hat stump, 'which is increased by the fact that the dem Side wall opposite the mixing chamber, sloping upwards at an outward angle Printing period, i.e. when the liquor moves from bottom to top in the dyeing room, the The position of the freely floating pieces of the work item changes automatically to one another without the need for external influence.

In the drawing is an embodiment of the subject matter of the invention for example shown.

Fig. I shows a section through the container and mixing chamber of the new one Dyeing machine in rest position, Fig. 2 the associated top view without filling.

Fig. 3 shows the movement of the dye liquor during the suction period, i.e. the movement from top to bottom through the dye container, Fig. q. same when the stump floats up during the pressure period.

Fig. 5 shows how the filling space is used for dyeing smaller quantities of piece goods can be reduced in size, so that a correspondingly lower one Amount of dye liquor can be used and still guarantees the same working effect remain.

The machine essentially consists of the dye container a for the Work piece goods, in particular * hat stumps, and the mixing room b, both through the partition c extending to the floor are separated. A sieve tray d is used for the support of the work item e during suction and at the same time for the passage of the dye liquor, while a similar sieve f in the upper part of the full-walled partition wall c prevents individual stumps from crossing over to the mixing chamber b during flooding. One wall of the container a, advantageously the one opposite the mixing space b, is arranged obliquely outwards, so that the filling space is much wider at the top is than at the sieve bottom d.

Below the sieve bottom d there is an opening in the partition c g provided, in which a propeller la rotates alternately right and left and thereby the dye liquor once through the bottom sieve d, when the direction of rotation is reversed but conveyed through the sieve wall f after the receiving roughening a for the work piece. The drive parts of the propeller are omitted in the drawing as insignificant, it is self-evident and well-known that the position of the propeller is just as well vertical, as well as can be arranged horizontally or at an angle. With the same success lets the propeller through any other device for fleet movement, z. B. Replace with a reversible pumping station or the like.

A tube i with a funnel-shaped mouthpiece opening into the mixing space b directly above the propeller h is used in a known manner to introduce the dissolved dye, which is reliably mixed with the liquor by the whirling action caused by the propeller.

The operation of the machine is as follows: The container is approx The piece of textile is filled with dye liquor up to the lower edge of the sieve wall f e, z. B. hat stumps, thrown in the appropriate amount and the propeller in Movement set. The dye liquor sucked off underneath the sieve bottom a flow down from the container a, followed by the individual workpieces this movement of the liquor, for the most part, are deposited on the sieve bottom d and thereby prevent the immediate passage of the fleet, the fleet is rather forced to penetrate the deposited piece of textile and thereby their dye to give to the fibers. The dye liquor sucked off below now winds through the propeller pushed up in the mixing space b, passes through the screen wall f and falls from there on the water level of the dye liquor, which has been lowered by the suction effect, whereby the work pieces that are still floating, for example, were washed over, mixed up and after be washed up the sloping wall of the container, come to rest there and relax also slowly settle down. This operation is shown in Fig. 3.

After the device has worked in this way for some time, becomes the direction of rotation of the propeller and thus the direction of movement of the dye liquor vice versa, the flow now goes from below through the holes in the sieve bottom d and drives the overlying stump upwards, thereby increasing the tightness loosens their position to each other.

Since the flow of the paint liquor moved by the propeller is now mainly acts in a straight line after the opposite sloping box wall and deflects gently upwards as a result of the inclination, are those on the sloping box wall deposited work pieces particularly briskly driven upwards, they mix there with the rest of the pieces, and there through the inflowing quantities of liquor on the one hand more and more work pieces get into the livelier flow, on the other hand due to the greater speed of the paint liquor on the sloping wall in a short time Time the whole content of the The filling chamber starts to move in a circular motion, thus the work material mixes in a much more reliable way without any external influence More confused than the most skilled worker can do with a mixer could.

The dye liquor raised by the pressure from below flows through the Sieve wall f and the mixing chamber b back to the propeller and describes it their circulation even during the printing period. Fig.q. shows this operation.

As soon as the direction of rotation of the propeller is back to suction is switched, the work item swimming in the current immediately strives for the Sieve bottom, the dye liquor pours out again through the mixing chamber and the sieve wall from above onto the goods, pushing all still floating pieces under complete flushing after the sloping wall, and the process is repeated exactly as before. Now, however, the work goods have become one because of the flooding and whirling around has completely changed position to one another, so is every single part of the influence exposed to the dye liquor differently than in the previous operation, and because that Switching the movement of the liquor takes place many times during the duration of a staining and the dye content of the liquor is supplemented more often, the guarantee is given, that each piece of the filling is saturated with a sufficient amount of dye and the dyeing is therefore carried out completely evenly without the worker the pieces to be colored were forcibly mixed up and thereby pressure points, color breaks or causing cracks. The work items are automatically redeployed by the flow exploited according to the invention so perfectly that with the device Not only fully milled hat stumps, but also, for example, a lab mat, d. H. half-milled hat felts can be dyed evenly without any damage.

Switching the direction of movement of the dye liquor can be done in a known manner Way either by hand or by special devices mechanically The duration of the suction and pressure periods can also be in any ratio adjusted to each other and the pressure period for the purpose of emptying the container be found until all the pieces have been fished out, since the top Acting current prevents the goods from sticking to the ground.

The facility is intended for processing smaller quantities, that the upper part of the partition c removed and the sieve f in its place is used (Fig. 5). As a result, the filling space a is reduced by about half, so that with a number of work pieces reduced to half the normal filling in the same container under the same conditions, d. H. with the same tightness and buoyancy expansion achieve the same coloring effect and a corresponding one reduced amount of liquor can be used.
