(Cl. 6810) ABSTRACT OF THE DISCLOSURE Yarn on bobbins is dyed when seated on perforated bobbin-carrying pipes, which in turn are connected to a mobile pipe system attachable to a source of treatment liquor. The flow path of liquor is uniform through all yarn-filled bobbins. The yarn-filled bobbins are spin-dried by structure releasing the bobbin-carrying pipes onto individual rotating spindles.

The present invention is directed to a textile-dyeing device or installation. This installation has a circulating pipe system for the circulating liquid dye consisting of a stationary pipe system and of a movable pipe system on a loading or feeding carriage which is suitable for passing or traveling through a dyeing station and at the same time also for traveling through consecutive treating stations in an endless path or course. The loading or feeding carriage is provided with perforated pipes for receiving the material. The perforated pipes carrying the bobbins or spools of yarn must be constituted as vertical bobbin-carrying pipes upon which the bobbins which are intended to be dyed are concentrically slipped or inserted. The present invention thus dyes bobbins or spools of yarn. Addition ally, the present invention is directed to and concerned with the loading or feeding carriage. This carriage comprises a pipe system which consists of pipes being arranged in the vertical central plane of the carriage. Laterally projecting distributor pipes extend from this piping and the bobbin-carrying pipes are, in each case, adapted to being mounted thereon in a suspended manner and may be coupled or connected thereto. The loading or feeding carriage has a holding device actuated jointly for the attachment and for detachment of the bobbin-carrying pipes. This arrangement renders it possible for all of the bobbin-carrying pipes at the loading or feeding carriage to be coupled and, uncoupled.

Furthermore, the present invention proposes two types of assembly between the distributor pipes and the bobbincarrying pipes. One of these assemblies is intended for the passage of the dye liquor through the bobbins from the inside toward the outside, and the other for the passage of the dye liquor from the outside to the inside.

An object of this invention is to provide a new apparatus for dyeing yarn.

The installation will now be described in further detail with reference to the drawings, wherein:

The installation as illustrated consists basically of The bobbin-carrying pipes 2 with the yarn-bobbins 3 are suspended on the loading carriage 1. The loading carriage is provided with wheels 4 which run in the U- shaped rails 5. By means of the transverse conveyor dolly 6, the loading carriage 1 is placed ahead of the pressure tank 7 so that, after locking door 9 is rolled open, it may be introduced into the tank 7 of station A by means of a pneumatic pushing device 8. The transverse conveyor dolly 6 runs or travels on the rails 10 and is moved by means of a drive motor and transmission 11 (FIGURE 2). The transverse conveyor dolly carries on its top the U-shaped rails 5 and the loading carriage 1.

The pipe system of the loading carriage consists of the vertical risers 1a and the horizontal distributor pipes 14 which jointly constitute a piping which is arranged in the vertical central plane of the carriage. The distributor pipes 14a and, respectively, 1412 extend laterally in both directions from the uper horizontal distributor pipe 14. Attached and coupled to distributor pipes 14a and 14b are the bobbin-carrying pipes 2. Pipes 2 are retained in each case, by lug portions 58a of hook-shaped levers 58.

Each carriage 1 (FIGS. 1 and 2) has two pipe couplings 15 which may be coupled with the pressure line 16 of the circulating pump 17. The pump is connected, with the suction pipe 18 which connects at its other end to the lowest point of the trough-shaped lower portion 19 of the pressure dyeing tank 7. q

The liquid dye is prepared in concentrated form in a storage container or tank 20. A certain quantity is removed from this tank, measured in the measuring tank 21 and mixed with a specific quantity of water from the water system 22. The inlet or lead supply into the pressure tank '7 takes place through the valve 23. When the two roller-type doors 9 in conjunction with the packings 24 have hermetically sealed the tank 7, circulating pump 17 is put into operation. The liquid dye circulates through the suction pipe 18, through the pump 17 and the pressure lines 16 and, from there, will pass into the pipe system of the loading carriage by way of the pipes 1a, 14, the distributor pipes 14a and 14b into the bobbin-carrying pipes 2 and from there into the yarn-bobbins 3 and impregnate the yarn wound on the bobbins as shown in FIGURE 3. It is possible also to pass the dye liquor through the bobbins from the outside toward the inside, as shown in FIGURE 4. In this case, the liquid dye is discharged through end-face openings 70 of the bobbincarrying pipe. As has been mentioned before, the liquid dye is collected in the trough-shaped lower portion 19 of the pressure dyeing tank and pumped again into circulation.

Heating of the liquid dye to a desired temperature may take place either by adding live steam which may be introduced through the connecting piece 25 (FIGURE 1), or by means of a heat exchanger 26 (FIGURE 2), or by both means.

After the completion of the dyeing process which resuires approximately from 8 to 20 minutes, the used bath is discharged by way of valve 27 (FIGURE 2) and the tank is thus rendered pressureless.

FIGURES 3 and 4 show the two diiferent ways of guiding the liquid dye through the material to be dyed.

FIGURE 3 shows an apparatus for passing the liquid dye from the inside to the outside of a bobbin. In each case, the same bobbin-carrying pipes may be used. Different distributor pipes 14a or 1417 are required in each case. These pipes are mountable upon individual loading carriages as desired.

The bobbin-carrying pipe 2 has a flanged-coupling at its bottom. At the top of the pipe, at flanged element 2b is arranged for axial displacement. The flanged-coupling elements will compress the yarn-bobbins axially. The upper flanged element may be locked, for this purpose, with the perforated pipe 2 by means of an elastic spring bolt 20.

As shown in FIGURE 4, a jacket 30 is disposed at the distributor pipe 14b which consists of a perforated inner liner 31 and a closed outer cover 32. The jacket 30 is open at the bottom thereof so that the bobbin-carrying pipes 2 with the bobbins 3 may be introduced. At the top of the jacket there is an opening with a sealing element 33. The end of the bobbin-carrying pipe is inserted through this opening and sealed. The liquid dye circulates-as shown by the arrowsthrough the pipes of the carriage into the interspace between the liner and cover 31 and 32, from there through the perforated jacket 31, and from the outside through the yarn-bobbins 3 into the inside of the perforated carrier pipe 2. It may flow out at the top and at the bottom through the openings 70 and be collected in the lower portion 19 of the pressure dyeing tank.

When the dyeing has been completed, the doors 9 will be opened and the loading carriage is transported from station A to station B. After the doors 9 have been opened a new loading carriage 1 will be introduced into station A. The transfer of the carriage is again effected by a pneumatic inserting device 8. The roller-type door 9, in closing pushes inclined surface 28 of the door (FIGURE 1) against roll 29 of the carriage and pushes the carriage further ahead the distance which is required for the door to close.

The treatment of the yarn-bobbins in station B consists of rinsing and further treatment, if desired. Station B has an open vat 40 (FIGURE 2) to which is connected, at the lowest point, the suction line 41 of the scavenger pump 42. The pressure line 43 may again be coupled with the pipe system of the carriage 1 by way of connecting pieces 15 and 1-6 and pipe couplings. Different rinsing or finishing baths are supplied to the vat 40 through the conduit 44 and controlled by valve 45.

The drain or discharge of the used baths at station B is made through the discharge valve 46. Any heating of the baths which is necessary may be made by heat exchanger 47.

After completion of a cycle at a station, one carriage each will travel to the next station, for example, the carriage from station B will travel to station C.

As shown in FIGURE 6, station C consists of centrifugal spindles 50 below the level of rails 5. The rails for receiving the carriage 1 are secured, in this station, to the piston rod 52 of cylinder 53 by means of cross member 51. By actuating this cylinder with compressed air or pressure fluid, the carriage 1 may be raised and lowered. The lowered position of the cross member is shown in FIGURE 6 by reference numeral 51a.

When the carriage is lowered, the perforated carrier pipes 2 with the yarn-bobbins 3 are lowered onto an extension 54 of the spindles St). The perforated bobbincarrying pipe is centered by opening 70 of the flanged element 2a and in a centering ring 55. In FIGURE 6, the left-hand upper part of the figure illustrates a bobbincarrying pipe 2 with yarn-bobbins 3 being slipped on or inserted, the passage of the liquid dye taking place from the outside to the inside. The right-hand upper part of the figure illustrates a carrier pipe 2 with yarn-bobbins 3 for a passage of the dye liquor from the inside toward the outside. In this arrangement, the centering piece 56 for the centrifugal spindle 54 is slidably arranged in the perforated pipe 2 so that it will rest on the flanged element 211 when it is removed from the centrifugal spindle. Thus the liquid dye will not be discharged at that point and will pass through the yarn-bobbins. When putting the centrifugal spindle into operation by means of the motor 57, the perforated pipe 2 with the yarn-bobbins 3 is caused to rotate and the adhering water is centrifuged After drying the carriage 1 is lowered again by means of the cylinder 53. At that time, the yarn carriers being again in the position of rest will slide into the connections of the carriage 1 being equipped with sealing rings 33.

The levers 58 are rotatably attached to the carriage 1 with a bearing piece 59. The upper lever part is drawn toward the center of the carriage 1 by the spring 60 so that lug portion 58a will automatically grasp or clamp under the flanged element 2a. The upper parts of the levers 58 rest against flat sections 61 (FIGURES 5 and 6). These flat sections are suspended by several clips or shackles 62 which are pivotally attached to the carriage. The sections 61 are displaced by means of a piston 63, piston rod 64 and traverse member 65 so that the sections 61 spread outwardly by means of shackles 62. By this action the levers 58 will cause lug portions 58a to move away from under the plate 2a and will release the carrier pipes. The piston drive 63 is rigidly disposed at each station where the disengagement of the carrier pipes is necessary (see in this connection FIGURE 5).

The locking of the carrier pipes takes place automatically by means of the hook-shaped levers 58 in that the lung portion 58a snaps under the flanged-coupling element 2a of the carrier pipe (see in this connection FIG- URE 4). The motion of piston 63 is now reversed and spring 60 will urge lugs 58a to clasp flanged element 2a.

After the carriage has traveled from station C onto the transverse conveyer dolly 6a, it is transferred ahead to station D by the movement or displacement of the transverse conveyer dolly and inserted into the dryer at D by the pneumatic piston 8a. After drying the carriage is transported to station E and unloaded there. The unloading may take place in precisely the same manner as has been described for the drainage operation in FIG- URE 6. By lowering the carriage 1 by means of piston 52, the carriage is lowered and released by actuation of the hook-shaped levers 58.

When the carriage 1 is raised it will travel into station F in order to receive there new carrier pipes with undyed yarn-bobbins. The receiving operation is effected in a manner analogous to the procedure which has been described for the drainage, i.e., by a renewed lowering of the carriage and coupling the carrier pipes.

For the so-called reductive treatment which is frequently applied in dyeing, a station B1 may additionally be disposed behind station B which operates in principle like station E.

Station C may also be equipped as a suction station. In that case, a suction device is present which sucks off the adhering water rather than centrifuges it as shown in FIGURE 6.

It should be understood, of course, that the foregoing disclosure relates to only preferred embodiments of the invention and that it is intended to cover all changes and modifications of the examples of the invention herein chosen for the purposes of the disclosure, which do not constitute departures from the spirit and scope of the invention set forth in the appended claims.
