Description

Device for winding and unwinding web-shaped Goods, e.g. floor coverings

The invention relates to a device »um Winding and unwinding of bag-shaped goods, e.g. .B. Floor coverings, on or from V / all, sleeves, or the like, which do it in a stand after! Paternosterart guided endless Chains are connected, consisting of at least one arranged between the movement paths of the rolls of goods, motor-driven friction roller, slide by means of a Travel against a spring force on the Y / arenrolle to be operated is employable.

Known unwinding and winding devices for the rolls of goods stored in such so-called paternoster stands are based mainly on the roll of goods being wound over the core. There must be a positive or frictional locking

Connection between the start of the V / arenbahnen, the winding core, the V / a rent rc gr o hr and el e cn W icke 'J a η drive. Sine Wicke! Device of this type is, for example, by the ü: i? -A3 '?. o33 o34 became known. Here is the goods support tube bsw. Provide the roller shaft with a x * drive pulley on which there is a friction lining. The actual winding device, which is also provided with a friction wheel, intervenes against this drive element. The roll of goods itself, for example a carpet roll, in the core of which there is a winding tube, must be in order. to be moved with the goods support tube of the winding device are connected. This is usually done by means of Xlemoihulsen or cones that are placed on the goods support tube.

In practice, a winding device is also known, which by acting on the outer surface of the roll of goods wraps. This winding device consists essentially of a horizontally displaceable carriage with swei continuous friction rollers that are motor-driven and attack the lower part of the roll of goods. In the rest position, the winding device is located between the rotating rolls of goods.

The disadvantage here is that the carpet roller paternoster has a large overall depth so that it can be moved horizontally able to accommodate arranged winding device,

Also kicked out when rolling up rolls of carpet large forces between the take-up device, tieai goods support tube and the receptacle in the chain.

The winding over the core of the carpet roll according to the known embodiment mentioned also has significant disadvantages on. With this type of winding, the beginning of the carpet can only be taken along with relatively complex additional devices possible. For example, in order to transfer the frictional forces, the entire paternoster is a friction wheel, which means an additional effort. The connection of every reissued Carpet roller with the goods support tube by means of Konusoe or cleram sleeves require additional work. In addition, when winding with a friction wheel, it is necessary that one goods carrier tube with centrally arranged bolts used. Therefore, such paternoster, which have Rxtentrisch mounted goods carrier tubes, such as the DT-PS i 273 973 shows can be converted at a relatively high cost if a winding device is installed subsequently shall be.

The invention is based on the object of developing a space-saving and cost-saving winding device that see automatically the variable roll diameter, also with out-of-round roll, regardless of how. storage

there is still a Kettenapannrad 43. The gearbox « motor 3o with the worm gear 31 for implementation the panning movement is in Pig. 6 shown.

The housing 45 of the worm gear 31 is about the Rohrstüok 46 and the plansche 44 and 47 with the gear motor 3o connected.

The worm shaft 48 is driven by the gear motor 3o via the coupling 49 and the bearing sleeve 5o. The bearing sleeve 5o is with the driven part of the coupling firmly connected. The one reaching into the bearing sleeve 5o The journal of the worm shaft 48 is serrated, as is the Bore of the bearing sleeve 5o. The worm shaft for the drive is thus connected to the bearing sleeve 5o in a rotationally locked manner and at the same time movable lengthways in it. The bearing sleeve is rotatably supported in the housing 45 by means of bearings 51. That the other end of the shaft of the worm shaft 48 is mounted in a needle ball bearing 52.

Απ housing 45 13t by means of splash 53 a spring clamping pot screwed on. A longitudinally displaceable guide 55 with disc springs 56 is located inside the Pederspanner 54. In the longitudinally displaceable guide 55 sits an axial deep groove ball bearing 57, at which the end of the worm shaft 48 is present. The guide 55 is therefore not axially rotatable, but only longitudinally adjustable.

The worm of worm shaft 48 is in engagement with worm wheel 58, then again with the worm shaft 29 is connected.

The puncture procedure is as follows:

This winding device is, like the one described first, also arranged in the middle between the uprights 2, 2 '. The rockers 36 hang vertically downwards with the friction roller in the resting state. A limit switch (not shown) ensures that the carpet paternoster can only be operated in this position.

The winding device is delivered during commissioning against the carpet roll 25 located at the winding station with the help of the G-etriebeuiotors 3o and the downstream one Worm gear 31 with one against the Disk springs 56 sliding worm shaft 4-3. The disc springs 56, which are preferably such acts with a degressive characteristic curve, are pretensioned in such a way that the winding roller is fed in, i.e. pivoted, The screw cannot move the torque resulting from its own weight. The direction of rotation of the worm wheel 53, and the pivot shaft 29 is indicated in FIG. 6 by means of an arrow. The rockers 36 with the friction roller 37 are thereby also pivoted in the indicated arrow direction.

Through the shaft end of the worm shaft 48, which on Ax: i. ul-Rillerikuyelloger 57 is pending, the guide 55 is moved with the plate springs 56 and a preload of the disc springs is generated.

The shift takes place until the guide 55 indicates a Limit switch A2 (FIG. 6) is actuated, which switches off the gear motor 30. The spring assembly 56 now pushes back the snake shaft 43 and thereby actuates the worm wheel 58 in the direction of the arrow, whereby the worm 48 acts like a rack. As a result, via the rocker arm 36, the friction roller 37 continues to move against the in the winding position located carpet roll 25 pressed. Only in this one Position the friction roller 37 can be put into operation.

Limit switch A-2 retains its off function during the unwinding process. By the shrinking carpet roll 25 moves the worm shaft 48 so v / eit back until a second indicated limit switch E-2 of the Gear motor 30 is set in motion again and the worm shaft 48 or the guide 55 is moved into the original position.
