Description
Winding Shaft and Method for Inserting a Winding Shaft into a Winding Device Description The invention relates to a winding shaft with a winding body and shaft journals that are situated at the ends of the winding body and are configured for insertion into a winding device.
The invention also relates to a method for inserting a winding shaft into a winding de-vice, in which the winding shaft has a winding body and shaft journals that are situated at the ends of the winding body, with which the winding shaft is inserted into corre-sponding recesses of the winding device.
Winding shafts for insertion into a winding device e.g. for winding web-like material such as webs of plastic film, fleece, and paper, are known and usually have a winding body equipped with winding journals at the ends of the winding body that are configured for insertion into the winding device and are held, for example, by corresponding winding arms of the device. In this connection, the winding shafts can be set into rotation indi-rectly through frictional contact with a contact roller or also directly by means of a rotary drive acting on the shaft journals and the web-like wound product.
Winding devices of this kind are known, for example, from DE 40 39 048 C2 and EP
1184312 Al.
The winding is usually carried out with a sleeve that is slid onto the winding body and affixed to it in a rotationally secured, but detachable fashion by suitable clamping means, e.g. a sleeve made of cardboard as described in DE 86 04 891 U1. In so doing, it is also possible in the sense of a so-called multi-use winding, to place a plurality of sleeves onto the winding shaft that each extend only over a part of the axial length of the winding body and to already correspondingly divide the supplied wound product in advance by means of longitudinal cuts for the separate uses.
Known winding devices for winding material webs of particularly large widths, however, usually use laterally arranged mounts, e.g. clamping arbors, that fix winding sleeves extending continuously across the entire width and transmit the torque, as described for example in DE 1 574 438 Al. With large winding widths, winding sleeves of this kind have less of a tendency to flex as compared to a solid winding shaft with a sleeve slid onto it. Winding devices with laterally arranged mounts for continuous winding sleeves, however, usually cannot accommodate winding shafts, making them unsuitable for a multi-use winding. In addition, when winding a narrow material web onto a winding device that is suitable for winding wide material webs, an unnecessarily wide winding sleeve must be kept on hand, which protrudes far beyond the finished winding and causes handling difficulties.
The object of the invention, therefore, is to propose winding shafts of the type men-tioned at the beginning as well as a method for inserting a winding shaft into winding devices, which shafts and method overcome the disadvantages of the prior art and offer a greater degree of flexibility when winding material webs.
In order to attain the stated object, the invention proposes a winding shaft that has the features of claim 1.
A method according to the invention for inserting a winding shaft into the winding device is the subject of the independent method claim 6.

In order to attain the stated object, the invention proposes a winding shaft that has the features of claim 1.
A method according to the invention for inserting a winding shaft into the winding device is the subject of the independent method claim 6.
- 2 -Advantageous embodiments and modifications of the invention are the subject of the dependent claims.
The invention proposes embodying a winding shaft so that the winding body is com-posed of a winding sleeve that is open at the ends and the shaft journals each have an insertion section with clamping means, with which they can be inserted into the ends of the winding sleeve and detachably clamped to the winding sleeve, and together consti-tute the winding shaft. A winding shaft that is composed in this way of a winding sleeve and shaft journals detachably fastened to the winding sleeve is equivalent in its dimen-sions to a known winding shaft, but on wide winding machines, also permits the winding of parent rolls on a continuous winding sleeve without the risk of excessive deflection and/or extreme weight of the winding shaft.
The corresponding winding device can be embodied according to the known design principles of a winding device for winding shafts and with the use of the winding shafts according to the invention, permits the winding onto a continuous sleeve and also, through the use of a conventional winding shaft with winding sleeves mounted on it, a multi-use winding in accordance with the respective requirements.
According to one proposal of the invention, the winding sleeve is composed of a tube section that is dimensionally stable, particularly with regard to deflection, whose compo-sition is based on metal, cardboard, or a plastic such as a fiber-reinforced plastic.
According to another proposal of the invention, the clamping means are composed of clamping jaws that are situated in the region of the insertion section, can be radially retracted and/or extended, and in the extended position, come into contact with the inside of the winding sleeve. The retraction and extension of the clamping jaws here can be carried out by means of compressed air, as is known in conventional winding shafts, so-called air shafts, in order to fix a winding sleeve made of cardboard or the like that has been slid on.
The winding shaft according to the invention can thus be preconfigured out of a winding sleeve and shaft journals, which are inserted with their insertion sections into the ends

The retraction and extension of the clamping jaws here can be carried out by means of compressed air, as is known in conventional winding shafts, so-called air shafts, in order to fix a winding sleeve made of cardboard or the like that has been slid on.
The winding shaft according to the invention can thus be preconfigured out of a winding sleeve and shaft journals, which are inserted with their insertion sections into the ends
- 3 -of the winding sleeve and locked in place, and can then then be inserted into the wind-ing device and maneuvered like a conventional winding shaft.
Between the shaft journal and the insertion section, a transition section is advanta-geously provided whose outer diameter essentially corresponds to the outer diameter of the winding sleeve and which constitutes a stop for the winding sleeve in the insertion process of the insertion section. This ensures an always definite, sufficient insertion of the insertion section into the end opening of the winding sleeve and on the other hand, makes it possible for the transition section to be produced in different widths so that the winding sleeve ¨ despite an existing large system width of the winding device ¨ can also be adapted as needed to a narrow width of the winding product to be wound. In this case, the transition sections of the shaft journals are embodied as significantly longer so that once again, the total length of the winding shaft that is required for the respective winding device is on the whole achieved.
The method according to the invention for inserting a winding shaft into the winding device is based on the fact that the winding shaft has a winding body and shaft journals situated at the ends of the winding body, with which the winding shaft is inserted into corresponding recesses in the winding device. The invention proposes performing the following steps for inserting the winding shaft into the winding device:
a) Production of a winding sleeve that is open at the ends and comprises the wind-ing body b) Production of shaft journals that have an insertion section and clamping means c) Insertion of the insertion section of each of the shaft journals into a respective end opening of the winding sleeve d) Clamping of the inserted insertion sections of the shaft journals in the winding sleeve to form the winding shaft e) Insertion of the winding shaft into the winding device In this regard, according to the invention, a winding shaft is formed by producing the open winding sleeve according to the width of the material web to be wound, inserting

- 4 -and clamping the shaft journals in the respective end openings of the winding sleeve, and then inserting the thus produced winding shaft into the winding device.
The clamping of the insertion section in the winding sleeve can be produced by radially extending clamping jaws out from the insertion section to the inner surface of the wind-ing sleeve; preferably, this is carried out pneumatically.
Other embodiments and details of the winding shaft according to the invention will be explained in greater detail below in conjunction with the drawings that show an exem-plary embodiment. In the drawings:
Fig. 1 shows a partial sectional view of a winding shaft according to the invention;
Fig. 2 shows the winding sleeve according to Fig. 1;
Fig. 3 shows a winding shaft according to the prior art.
Fig. 3 shows a winding shaft according to the prior art for insertion into a corresponding-ly embodied winding device.
Such a winding shaft 1 includes a winding body 2 and at both ends of the winding body, shaft journals 11 that are positioned on the longitudinal axis L and configured for inser-tion into the winding device. The winding body 2 is embodied as intrinsically cylindrical and before being placed into use, is completed with a winding sleeve, not shown here, made of cardboard or the like, which is slid in the direction of the longitudinal axis L onto the winding body 2 so as to encompass the latter and is affixed to the winding shaft in a rotationally secured fashion by means of compressed air-operated clamping jaws that can be radially extended out from the circumference of the winding body 2.
The cardboard sleeve that is affixed in this way can be embodied of one piece or of multiple pieces in order to thus enable a so-called multi-use winding.
The clamping of the insertion section in the winding sleeve can be produced by radially extending clamping jaws out from the insertion section to the inner surface of the wind-ing sleeve; preferably, this is carried out pneumatically.
Other embodiments and details of the winding shaft according to the invention will be explained in greater detail below in conjunction with the drawings that show an exem-plary embodiment. In the drawings:
Fig. 1 shows a partial sectional view of a winding shaft according to the invention;
Fig. 2 shows the winding sleeve according to Fig. 1;
Fig. 3 shows a winding shaft according to the prior art.
Fig. 3 shows a winding shaft according to the prior art for insertion into a corresponding-ly embodied winding device.
Such a winding shaft 1 includes a winding body 2 and at both ends of the winding body, shaft journals 11 that are positioned on the longitudinal axis L and configured for inser-tion into the winding device. The winding body 2 is embodied as intrinsically cylindrical and before being placed into use, is completed with a winding sleeve, not shown here, made of cardboard or the like, which is slid in the direction of the longitudinal axis L onto the winding body 2 so as to encompass the latter and is affixed to the winding shaft in a rotationally secured fashion by means of compressed air-operated clamping jaws that can be radially extended out from the circumference of the winding body 2.
The cardboard sleeve that is affixed in this way can be embodied of one piece or of multiple pieces in order to thus enable a so-called multi-use winding.
- 5 -After completion of the winding process, the winding shaft together with the winding that has been produced on the at least one winding sleeve is removed from the winding device and the clamping jaws 111 are retracted into the circumference of the winding body 2 by a releasing of the introduced compressed air so that the winding shaft 1 can then be removed from the at least one winding sleeve and used for a new winding.
Figs. 1 and 2 show a winding shaft 1 according to the invention, whose outer contour largely coincides with that of the winding shaft from the prior art shown in Fig. 3; in particular, the shaft journals 11 are correspondingly embodied so that such a winding shaft 1 can also be used in a winding device that is configured for winding shafts ac-cording to Fig. 3.
The winding body of the winding shaft according to Figs. 1 and 2 is composed of a winding sleeve 10 that is open at the end and is composed, for example, of metal, which for the winding of a parent roll, is directly wound with the material web that is to be wound, i.e. no other sleeve made of cardboard or the like is slid onto it as a core.
In order to use such a winding sleeve 10 with open ends 100 in a winding device for winding shafts according to the embodiment in Fig. 3, the shaft journals 11 provided at the ends are each embodied with an insertion section 110, which can each be inserted into the respective open ends 100 of the winding sleeve 10 at the two ends thereof. A
transition section 112 between the insertion section 110 and the shaft journal 11 in this case forms a stop that is labeled with the reference numeral 112a, against which the end of the winding sleeve 10 rests. In this inserted position shown in Fig. 1, the insertion sections 110 are then affixed to the inner surface I of the winding sleeve 10 in a rota-tionally secured fashion by means of a radial extension of clamping jaws 111 from the circumference of the insertion section 10; this extension can be carried out in an intrin-sically known fashion by means of compressed air, which can be introduced, for exam-ple, via a corresponding valve and an internal compressed air line in the shaft journal 11.
In this way, a temporary, detachable connection between the two shaft journals 11 and the winding sleeve 10 is produced via the respective insertion sections 110;
in this state, the winding sleeve 10 and the clamped shaft journals 11 jointly form a winding shaft 1
Figs. 1 and 2 show a winding shaft 1 according to the invention, whose outer contour largely coincides with that of the winding shaft from the prior art shown in Fig. 3; in particular, the shaft journals 11 are correspondingly embodied so that such a winding shaft 1 can also be used in a winding device that is configured for winding shafts ac-cording to Fig. 3.
The winding body of the winding shaft according to Figs. 1 and 2 is composed of a winding sleeve 10 that is open at the end and is composed, for example, of metal, which for the winding of a parent roll, is directly wound with the material web that is to be wound, i.e. no other sleeve made of cardboard or the like is slid onto it as a core.
In order to use such a winding sleeve 10 with open ends 100 in a winding device for winding shafts according to the embodiment in Fig. 3, the shaft journals 11 provided at the ends are each embodied with an insertion section 110, which can each be inserted into the respective open ends 100 of the winding sleeve 10 at the two ends thereof. A
transition section 112 between the insertion section 110 and the shaft journal 11 in this case forms a stop that is labeled with the reference numeral 112a, against which the end of the winding sleeve 10 rests. In this inserted position shown in Fig. 1, the insertion sections 110 are then affixed to the inner surface I of the winding sleeve 10 in a rota-tionally secured fashion by means of a radial extension of clamping jaws 111 from the circumference of the insertion section 10; this extension can be carried out in an intrin-sically known fashion by means of compressed air, which can be introduced, for exam-ple, via a corresponding valve and an internal compressed air line in the shaft journal 11.
In this way, a temporary, detachable connection between the two shaft journals 11 and the winding sleeve 10 is produced via the respective insertion sections 110;
in this state, the winding sleeve 10 and the clamped shaft journals 11 jointly form a winding shaft 1
- 6 -whose configuration corresponds to that of the winding shaft according to Fig.
3 so that they can be inserted into a correspondingly prepared winding device.
After completion of the winding procedure, the introduced compressed air is released in order to retract the clamping jaws back into the circumference of the insertion sections 110 so that the rotationally secured connection between the winding sleeve 10 and the insertion sections 110 of the shaft journals 11 is released and the latter can be removed from the end openings 100 of the winding sleeve 10. Consequently, the isolated winding sleeve 10 then remains along with the winding, not shown here, that has been wound onto it.
It is clear that through the embodiment of the winding shaft according to the invention, a winding of parent rolls with a continuous winding sleeve 10 can also be carried out in winding devices that are intrinsically embodied for accommodating conventional winding shafts 1 according to the exemplary embodiment in Fig. 3. The winding device therefore does not require any structural modification and it is possible to flexibly react to each winding task individually.
If in a winding device that is designed for large winding widths, a significantly narrower material web by contrast is to be wound onto a winding sleeve 10 of a corresponding width, then it is only necessary to correspondingly adapt the width of the transition region 112, in particular to enlarge it, so that an on the whole uniform overall length of the winding shaft 1 is achieved, allowing different winding sleeve lengths to be used without having to change the width of the winding device.
With the winding shaft according to the invention, it is possible to alternatively use winding shafts or winding sleeves in a single winding device. While the use of winding shafts according to Fig. 3 makes it possible in particular to produce a multi-use winding, it is alternatively possible, through the use of a winding shaft with a continuous winding sleeve according to Fig. 1, to also wind a parent roll with a large width.
3 so that they can be inserted into a correspondingly prepared winding device.
After completion of the winding procedure, the introduced compressed air is released in order to retract the clamping jaws back into the circumference of the insertion sections 110 so that the rotationally secured connection between the winding sleeve 10 and the insertion sections 110 of the shaft journals 11 is released and the latter can be removed from the end openings 100 of the winding sleeve 10. Consequently, the isolated winding sleeve 10 then remains along with the winding, not shown here, that has been wound onto it.
It is clear that through the embodiment of the winding shaft according to the invention, a winding of parent rolls with a continuous winding sleeve 10 can also be carried out in winding devices that are intrinsically embodied for accommodating conventional winding shafts 1 according to the exemplary embodiment in Fig. 3. The winding device therefore does not require any structural modification and it is possible to flexibly react to each winding task individually.
If in a winding device that is designed for large winding widths, a significantly narrower material web by contrast is to be wound onto a winding sleeve 10 of a corresponding width, then it is only necessary to correspondingly adapt the width of the transition region 112, in particular to enlarge it, so that an on the whole uniform overall length of the winding shaft 1 is achieved, allowing different winding sleeve lengths to be used without having to change the width of the winding device.
With the winding shaft according to the invention, it is possible to alternatively use winding shafts or winding sleeves in a single winding device. While the use of winding shafts according to Fig. 3 makes it possible in particular to produce a multi-use winding, it is alternatively possible, through the use of a winding shaft with a continuous winding sleeve according to Fig. 1, to also wind a parent roll with a large width.
