United States Patent 7 Claims US. Cl. 242-55 Int. Cl. B65h 75/02 ABSTRACT OF THE DISCLOSURE The present invention concerns a double-layer winding device, especially for textile webs, which operates in conformity with the duplex winding with two hank rollers of changing direction of rotation for storing the goods which are withdrawn in a continuous uninterrupted process.
The invention is characterized in that one of the two hank rollers is rotatably journalled in a stationary hearing whereas the second hank roller is tiltable about the first hank roller in steps of 180 while being tilted in this way in an intermittent manner. The tiltable or second hank roller is frictionally driven by the first hank roller and the goods are wound onto the respective empty hank roller while forming a fold at the start of the lastmentioned winding-up operation.
The invention relates to a double winder for treating textile webs in which by alternately loading two rotatable hank rollers, the textile webs can be stored for a longer period of time in a container although the webs are being withdrawn from the container in a continuous uninterrupted process.
It is an object of the present invention to provide a double winder of this type which is materially improved in structural and functional respect.
It is another object of this invention to provide a double winder which will considerably simplify the driving arrangement therefor.
These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawings, in which:
FIG. 1 is a diagrammatic illustration of a side view of a double winder with all important mechanical devices in connection with a pressure bleaching container indicated in dash lines.
FIGS. 2 to 9 diametrically illustrate the various phases during the alternate loading and unloading of the hank rollers.
The above outlined objects have been realized according to the present invention by arranging the journal for one of the two rollers stationarily and providing the thus journalled roller with a drive, whereas the second roller is adapted to be moved in steps over 180 relative to said first roller but always in the same direction in a counterclockwise sense. This movement is effected intermittently, and the second roller is rotated by the first roller by friction. Furthermore, with each intermittent movement of the second roller, the winding direction of the goods is reversed and the goods are by means of pivotable compressed air nozzles or in view of the adhesion by moisture pressed into the gap between the two rollers whereby the respective empty roller is rotated.
The advantage of this device consists in that in view of the rotation of the movable hank roller by friction or by a reduced distance between said rollers, the driving mechanism will be greatly simplified, while the overall size of the device will be considerably reduced. Furthermore, the bend or fold at the start of the two-layer winding will be effected without mechanical means, and due to the mutual turning of the rollers while they are pressed against each other under a substantially constant pressure, the goods will be in firmer engagement with the rollers.
Referring now to the drawings in detail, roller 1 is mounted on a shaft 3a journalled in a stationarily arranged bearing 3, whereas roller 2 is journalled in a radially movable bearing 4 and is adapted to be moved in the direction of the arrows A (FIGS. 29) always in counterclockwise direction and, more specifically, each time by By a correspondingly strong shaft 3a, roller 1 is alternately rotated in clockwise and counterclockwise direction by a wheel 1a and a reversible motor 18. Also arranged on shaft 3a are two strong arms'5, and 5a which on one side support guiding means 6 for the displacement of bearing 4 when the wound up material increases whereas the other arm carries a compressed air operable cylinder piston system 7. Said cylinder piston system is adapted by means of a link system 7a to pull the two bearings 4 of the movable roller 2 under constant pressure against the driving roller 1. The pivotal movement of the two arms 5, 5a is effected by two gears 8a and 8 by means of motor 9 and transmission means 9a. The start of the movement for the counterclockwise rotation of the arms 5 and 5a and the starting of the change of the driving sense of the main roller 1 is brought about by closing limit switch 20 by a nose 21 of the link system 7a and by contact 20a when rollers 1 and 2 are fully wound. The electrical wiring of the control circuit is not shown inasmuch as circuits of such type are well known in the art of reversible motors. The arrangement also comprises a nozzle pipe 12 which is arranged above the driving roller and is pivotable at 14 by means of a lever 13. In view of the fact that the two rollers roll upon each other, not only a compact structure is obtained but also the advantage that the winder can be built into closed processing chambers, especially into those which are under pressure, whereby the double winder will act as a storing device with a considerable increase in the staying time during which the goods stay in the container in a manner similar to I-boxes.
Thus it is possible to reduce the working pressure which in turn considerably reduces the costs for the pressure container. This possibility is illustrated in FIG. 1 by indicating a pressure container 16 in dash lines. With this arrangement, on the right-hand side of the winder, there is provided a compensator 15 which assures the tensioning of the web when roller 2 is shifting in the other direction. With installations of this type, the feeding and withdrawal of the goods 10 is effected through pressuretight bodies 17 which are well known in the art and, therefore, are illustrated diagrammatically only in FIG. 1. When installing a double winder according to the present invention in a textile treating container, the driving gears 8 together with the drive for the roller 1 are advantageously arranged outside the container.
Operation The operation of the arrangement is as follows: The goods 10 passing into the arrangement from the top over feeding rollers F have their start 11 passed between and through the two rollers 1 and 2 and wound around main roller 1 in a single layer. Thereupon, the drive for shaft 3a is made effective so that said shaft turns around in clockwise direction (arrow B) as shown in FIG. 2, until half of the total winding diameter has been obtained. After this has been accomplished, the pivotable roller 2 is shifted in counterclockwise direction (arrow A, FIG- URE 2) to its left-hand position, as shown in FIG. 3. Furthermore, the nozzle tube 12 is brought into the position shown in FIG. 4 in which it is at the level of the roller bite between the two rollers 1 and 2 whereupon the web of goods is by means of compressed air leaving said nozzle 12, pressed into said bit. When at this time, the direction of rotation of main roller 2 is changed, the goods will be wound upon roller 2 in a double layer. This depositing of the goods in a double layer is due to the fact that on one hand the oncoming goods are deposited on roller 2, and on the other hand the goods previously deposited on roller 1 are likewise deposited on roller 2. After the winding diameter of roller 2 has reached its desired maximum or full value, the main roller -1 is empty and the start section 11 of the goods which is now on top or on the outside of pivotable roller 2 is thereupon withdawn, as indicated by the dash-line a (FIG. 1) through compensator or cushioning system 15, while at the same time the full hank of roller 2 is shifted by 180 into its right-hand position, as shown in FIG. 6. Nozzle tube 12 is then again moved into the roller gap, and the oncoming goods are wound upon main roller 1. As soon as main roller 1 is full (FIG. 8), the empty roller (FIG. 2) again is shifted by 180 in counterclockwise direction so as to reach its left-hand position shown in FIG. 9. Thereupon nozzle tube 12 is again moved into the bite or gap between rollers 1 and 2 and the cycle is repeated, as mentioned above in connection with FIG. 7, and the goods are again wound on roller 2 as shown in FIG. 5.
Inasmuch as the oncoming goods are impregnated with a bleaching or other liquor, it will be appreciated that when reversing the direction of rotation, the goods will by themselves adhere to the respective empty roller and form the bending fold so that in most fields of application, the arrangement of a nozzle tube Will not be necessary.
It is, of course, to be understood that the present invention is, by no means, limited to the particular arrangement referred to above and illustrated in the drawings, but also comprises any modifications within the scope of the appended claims. Thus it is also possible to drive the individual rollers by means of shafts coupled through the intervention of differential transmissions in a manner similar to that employed in connection with jigs. It is merely important that one roller has its bearing stationarily arranged while the second roller moves in intermittent steps about the first roller in the same direction.
