Take-up device for winding a web-shaped Flat structure on a winding core

The present invention relates to a winding device for winding a sheet-like fabric onto a peripherally driven, cylindrical winding core.

In web-shaped products processing or manufacturing Industries, especially in the textile industry, are many of the ordering machines, e.g. those for Treatment of sheet-like fabrics such as fabrics, Knitted, fleece, paper and the like, at the outlet end for Winding of the manufactured in the machine in question or treated web on Grosskaulen with

809848/0569

so-called peripheral winders are provided, i.e. with pendulum-mounted, driven drums or rollers for the circumferential drive and often also for the simultaneous generation of the required density of the on one Winding core to be produced winding.

Winding devices are used to wind up small and medium-sized amounts of sheet-like structures known, the two stored in a frame parallel to each other, but without contact with each other Have support rollers which are intended to have an axially parallel between them resting on them and over an axially central winding rod in brackets displaceably guided and releasably fastened winding core or to support the winding formed on it during the winding process.

However, the handling of the previously known winding devices of this type is very labor-intensive and requires usually additional auxiliary devices, such as winding bars, and especially for inserting the winding cores often also tools, e.g. for fixing opening cones to be pushed onto both sides of the winding bar. In addition, it has hitherto been necessary to have a winding device at the outlet of each such manufacturing machine to be attached, which could then only be used in connection with this assigned machine.

809848/0569

The object of the present invention is to provide a winding device of the type mentioned above, in particular the clamping of an empty Winding core but also the removal of a wound winding in a simple way as well as quickly and safely without Tools enables and at the same time for use on different machines and thus for different winding cores Large, in particular different lengths and / or diameters without additional devices and without Additional effort can be used.

To solve this problem, the winding device according to the invention is characterized in that it for releasably holding the winding core two in an axis parallel to the axes of the lay-up rollers having opposing centering cones, which are freely rotatably mounted in uprights, which on the one hand in the frame axially adjustable towards and away from each other and on the other hand in one Parallel guidance in the perpendicular to the plane that contains the axes of the lay-on rollers and whose distance bisecting the plane can be moved.

The accompanying drawing shows an example of an embodiment of a winding device according to the invention shown. It shows:

Figure 1 is an end view of this device, and

Fig. 2 is a side view of the device.

The winding device shown has a frame 2 that can be moved on wheels 1. In this frame 2 are, in corresponding bearings 6 for their shaft journals 3, two support rollers 4 or 5 freely rotatable so that they run parallel to each other without touching each other, their axes lying in a horizontal plane A (Fig.l).

The lay-up rollers 4 and 5 are intended in known Way, a support for a winding core 7 or for the winding W generated thereon during the winding process to form on which it can roll into place.

The bracket to be described below for the winding core 7 should meet several criteria:

The winding core 7 must be freely rotatable; the holder is intended to clamp the empty winding core 7 and the removal of the same with the generated lap W after completion of the winding process in the simplest possible manner Enable them wisely, quickly and securely; the bracket must be in accordance with the increasing diameter of the winding W produced during the winding process on the winding core 7 in the direction perpendicular to the plane A (Fig.l), which

809848/0569

contains the axes of the lay-up rollers 4.5, extending and the distance bisecting the plane B (Fig. 1) can be displaced.

The holder that perfectly fulfills these criteria comprises two in the illustrated embodiment in an axis parallel to the axes of the support car 4,5 opposite centering cones 8, which are freely rotatably mounted in stands 9 with respect to the axis just mentioned. These uprights 9 extend vertically through the gap between the two support rollers 4 and 5 and are each axially slidable guided in a tubular slide guide 10. A threaded sleeve is provided on each sliding guide 10. The threaded sleeves of the two plain bearings 10 are axially aligned with one another and are of a threaded spindle 11 interspersed, which is rotatably mounted in stationary bearings of the frame 2 and on her one end carries a handwheel 12. As can be easily understood by doing this, namely by operating the handwheel 12 via a thereby caused displacement of the sliding guides 10 along the spindle 11 away from one another or against each other, the distance between the centering cones can be adjusted.

809848/0569

To use the winding device shown and described, it becomes an existing one Peripheral winder P driven, as is shown, for example, schematically in Fig. 1 by dash-dotted lines and, as is usually the case, at the end of the flow of systems for the production or treatment of sheet-like fabrics is available. Alternatively, the device could also be brought to its place of work by means of a lift truck be spent, in which case the arrangement of the wheels 1 could be dispensed with.

Thereafter, the winding core 7, on which the to be wound Web wrapped should be used. The device allows the insertion of winding cores Different diameters, lengths and materials, e.g. wood, plastic and aluminum, provided they are tubular or at least at their ends with recesses for engaging the centering cones 8 provided. Before inserting the winding core, the operator moves it by turning the handwheel 12 the centering cones 8 so far apart that the winding core W comfortably between the cones on the two support rollers 4.5 can be placed. Now the cones 8 have to be moved by moving the uprights 9 be brought in their sliding guides 10 to the level of the winding core opening, which varies depending on the thickness or diameter of the winding body in question is more or less high above the lay-up rollers.

809848/0569

To facilitate this handling, outwardly protruding handles 13 are provided on the stands. So that this vertical adjustment of the centering cones and the subsequent insertion of the cones into the winding core as possible can be done quickly and precisely, the weight of cone 8 and stand 9 is on each side Via a cable pull 14 which runs over a roller 15, compensated by a counterweight 16 that runs in a tube 17 or a guide.

Then, by turning the handwheel 12, the centering cones 8 are shifted against each other until they themselves * - centering slide into the openings of the winding core 7 and this with respect to its holder store rotatable.

Now the beginning of the fabric to be wound can be started are attached to the winding core 7 used in this way. As this is usually a rotation of the winding core requires around its axis and this is initially not connected to any drive is a Shaft journal 3 of one of the support rollers 4 and / or 5 advantageously with a plug-in coupling for receiving a plug-in crank 18 shown in Fig. 2 provided via which over the relevant support roller as Circumferential drive of the winding core can be rotated as far as necessary for commissioning. now is the

809848/0569

Wrapping device ready for the wrapping process, which is achieved by lowering and putting the non-device into operation Peripheral winding drive P can be carried out in a known manner.

After completion of the winding process, the winder P is lifted off again and the handwheel the cones 8 moved out of engagement with the winding core. After that, the now over his winding W Again, the winding core lying freely on the lay-up rollers 4.5, together with the winding, is removed from the device which in turn is ready to receive a winding core for the next winding process.

For the use of the winding device described for winding particularly sensitive and delicate webs of material while avoiding the formation of wrinkles, it may be useful, if necessary, to use one or both of the lay-on rollers 4 and / or 5 to drive in addition. This can be advantageous over an expedient over a Slip clutch attachable additional drive take place, then winding core or winding with minimal local Friction is set in rotation and held by two or three rollers acting as circumferential winders will.

809848/0569

Such an additional drive in the form of a motor is indicated at 19 in FIG. 2. It would of course be conceivable to design such an optional additional drive so that it connects to the same one provided for the hand crank 18 Plug-in coupling can be connected.
