Abstract
(57) Abstract Described is a reel designed as a core on whose curved surface (1) a strip of material, in particular pa-per. can be wound The ends of the reel have coupling elements (2, 3) by which the reel can be connected to a winding drive as well as to another reel. Several reels can be fitted together to produce a core on which several strips of material (4) can be wound si-multaneously. On completion of the winding opera-tion, the rolls of material can be separated from each other, the coupling elements (2, 3) forming trunnions which project out along the longitudinal axis of the reel.
Description
2 1 `~ 2 wo 93/10033 FILE, P~ N ~ ,r.~ FJL ~ PCT/AT92/00131 T-~ TRANS!. `~ i 10 A ROLL CARRIER
The present invention relates to a roll carrier, on the peripheral surface of which a band of material can be wound and which incorporates coupling elements at its ends, these being used to connect it to a winder drive system.
Such a roll carrier i5 described, for example, in US-A 4,754,537. ~:
An end cap is inserted in both ends of a tube and this end cap incorporates a rectangular [square] opening to connect it to a drive shaft. The roll carrier is intended, in particular, for textiles and, for this reason, is very long, ~or example, two meters long. ;
I~ it is intended to wind bands o~ material that are of lesser width, for example, toilet paper or the like, usually a cardboard sleeve, the length of which is a multiple of its subsequent length, is slid onto a driven winder core or mandrel of a winding machine and fixed in position, in particular by being braced in position. Relatively complicated mechanisms to do this are known. The roll carrier that has a plurality of bands of material wound onto it is then released ~rom the winding core, i--drawn off the core and cut to the requirad lengths. As soon as the material band that has been wound onto the cores has been used up, the empty cardboard sleeve is discarded. The cardboard sleeve itself is wound up from a plurality of layers of paper.
Thus, all in all, this r~sults in a relatively costly, and labour and cost-intensive manufacturing process, both for the roll carrler and for the rolls that are produced.
Xt is the task of the present invention to eliminate this disadvantage, and to this end it proposes that a roll carrier, in -"` 2~23 1~2 wo 93/10033 ~~ ~ PCT/AT92/00131 which the end coupling elements are so formed that a number of roll carriers can be combined to form a winding core that winds a plurality of bands of material simultaneously, be used for narrow bands of material such as toilet paper or the like. This means that the former cardboard sleeves nePd not be used and the connecting system between the winding cores and the roll carriers becomes unnecessary. After removal of the winding core from the winding device, the individual rolls can be separated from each other. The roll carrier according to the present invention is made, in particular, from plastic, for example, by injection moulding, so that the coupling elements that are required to establish the necessary connections and to connect the roll carrier to the drive system can be moulded in place at the same time. This makes it possible to achieve a smaller roll carrier diameter than is possible using wound-up cardboard sleeves, so that a significantly longer strip of material can be accommodated on the same roll diameter. Depending on the value of the material used for the roll carrier, when the strip of material has been used up, this can be discarded, although it is preferred that it be returned for re-use.
Very o~ten, dispensers are used in which at least two such rolls can he accommodated, in the case of rolls o~ toilet paper, rolls of paper towels, household rolls, rolls of plastic or metal foil such as are used for domestic purposes, and for rolls of bags, and the like. After the first roll has been used up, a second is available for use, and this slips down guides into the dispensing "
position. A preferred embodiment that is suitable for this purpose is such that both coupling elements extend axially beyond the periphery and form guide or bearing journals. Using the rolls in this type of dispenser also makes it simpler to collect the empty roll carriers for re-use, for they can be collected in a storage area within the dispenser. They are joined together 3'1~
Wo 93/10033 -3 ~ PCT/AT92/00131 and installed once again on the drive system of the winding device as winding cores.
Another embodiment is such that at least one coupling element has spring-type detent elements.
The present invention will be described in greater detail below on the basis of the drawings appended hereto, without being restricted to these. These drawings show the following:
Figure 1: a first embodiment of a roll carrier, in longitudinal i~
section;
Figure 2: a winding core made up of a plurality of roll carriers as in figure 1, also in longitudinal section;
Figure 3: a secand embodiment of a roll carrier, in longitudinal section;
Figure 4: a cross-section on the line IV-IV in figure 3;
Figure 5: an end view of the roll carriex as viewed in the direction indicated by the arrow A in figure 3.
A roll carrier, particularly one that is injection-moulded from plastic and which can be used as a winding core, has a middle section on the peripheral section 1 of which a strip 4 of material can be wound. A coupling element 2, 3 extends from both ends and of these at least one, for example the coupling element 2, can be connected to a winding drive system.
As is shown in figures 1 and 2, a coupling element is formed by a journal 2: this protrudes from an inner intermediate wall 5 of the sleeve-like roll carrier so as to leave an annular gap between it and the peripheral wall. This journal is of small diameter. The journal 2 is, for example, formed so as to ba non-circular or provided with a dog in the peripheral direction so as to achieve a positive fit with a winding drive system (not sho~n `" 2~23~
Wo 93/10033 ~4 ~ PCT/AT92/00131 herein) in the peripheral direction. The second coupling element is in the form of a hollow journal 3, the diameter and wall thickness of whlch correspond to the annular gap in the first coupling element. As figure 2 shows, despite the projection on both ends, this results in a close fitting arrangement of the peripheral surfaces 1 of the roll carriers that have been combined, with, in each instance, a journal ~ fitting into a hollow journal 3. A plurality of bands 4 of material can be wound simultaneously on a winding core formed in this way, said bands resulting, for example, from cutting up a wide strip. As soon as the rolls have been wound, the winding core is taken off the winding drive system, when the individual rolls or roll carriers can be withdrawn from each other. When this is done, at least some of the coupling elements 2, 3 extend axially beyond the roll and these can then be used as the bearing journals for --~
the roll in a dispenser.
,., In the embodiment shown in figures 3 to 5, the coupling elements 2, 3 snap into each other. To this end, windows 6 are formed in the end areas of the peripheral wall that support the journals 2 and the hollow journal 3 incorporates two spring detent tabs 7 that are separated by slots 8; when the roller carriers are assembled these detent tabs 7 snap into the windows 6. The detent tabs 7 have an outer surface that rises to one side so that there is a positive fit only in the direction of rotation during the winding process, but no such positive fit in the opposite direction. Thus, the roll carriers can be separated from each other very easily by rotation.
The coupling elements 2, ~ can be formed in a similar manner so that they can be assembled as desired. Thus, it is possible to provide the face ends with dogs that fit into each other axially.
