Abstract
ABSTRACT
A method is disclosed for removing a fully wound roll from a centreless winding machine and replacing it with a winding sleeve. The method is characterized by the winding sleeve being inserted from the side to which the wound roll was ejected so that the sleeve is partly encircled by the slackened strip of material still attached to the wound roll. The strip is then severed and attached to the winding sleeve.

Description
This invention rela-tes to a method for changing wound rolls and winding sleeves on centreless winding machines, wherein the fully wound roll is pushed away, a ~inding sleeve is inserted, the strip of material is severed and secured to a winding sleeve, and the wound roll is taken away.
Various methods are known for changingwound rolls and winding sleeves on centreless winding machines, that disclosed in German oS 27 09 684 being used here as a generic example. In this known method, the fully wound roll is lifted slightly off a ~0 carrier rol]. ~ winding sleeve is allowed to roll through the gap thus formed into the gap between the carrier rolls. The wound roll then returns to its original position in the carrier roll bed, after which it is pushed away over the other carrier roll. The strip of material is then secured to the winding sleeve by a device which is swung in, and the strip of material is then severed.
The disadvantage of this known method is that only wind-ing sleeves of a certain size may be inserted, i,e. those which fit into the nip between the carrier rolls before the wound roll is ejected. Since this nip is relatively small, the known method i5 used only for winding paper onto sleeves~
The method according to ~erman OS 27 09 684 cannot be used ~or winding cardboard, ~hich is wound onto large diameter sleeves. The same applies to another known method (German OS
26 38 368) in which the winding slee~e is pushed, in the direction of the carrier roll axes, into the nip ~ormed between the carrier rolls and the wound roll. A-~ter the latter has been ~d, the . .

strip o~ material can be secured to the winding sleeve and, after it has been severed, the wound roll may be taken away.
German Patent 21 18 963 discloses another method which is more complex. In this case the wound roll is pushed away, the strip of material is severed, the wound roll is taken away, and the start of the strip of material is glued to the winding sleeve.
However, this method requires that the two carrier rolls be separated in order to move the windin~ sleeve between the carrier rolls into the carrier roll bed. The necessary mobile mounting for the carrier rolls is relatively costly.
Severing the strip of material and taking the wound roll away be~ore the sleeve is inserted into the carrier roll bed raises the di~ficulty of holding the start of the new strip of material, produced a~ter the strip is severed, which must be secured to the new winding sleeve. In the case of automatic changing equipment this is essential. In the case o~ the apparatus disclosed in German OS 29 20 707, this problem is solved in that the start of the new strip of makerial; produced after the strip has been severed, is caused to adhere to the periphery o~ a carrier roll by means o~ a vacuum produced in the said carrier roll. However, the necessary equipment i5 relatively costly.
It is the purpose o~ the present invention to provide a method which will permit automatic wound roll winding sleeve changeovers, using sleeves o~ dl~erent diameters, to be carried out in the simplest possible manner, i.e~ with simple means and in the shortest possible time.

According to the invention there is provided a method for changing wound rolls and winding sleeves on centreless winding machines, wherein the fully wound roll is pushed away, a winding sleeve is inserted, the strip of material is severed and secured to the winding sleeve, and the wound roll is taken away, characteri~ed in that the winding sleeve is inser-ted from the side to which the wound roll was ejected and is therefore partly encircled by the slackened strip of materlal, whereupon the latter is severed and is attached to the winding sleeve.
The method according to the invention has the advantage of making it possi~le to insert winding sleeves of almost unlimited diameter. This is achieved by ejecting the fully wound roll into a position which does not interfere with the insertion of a new winding sleeve. Since the windlng sleeve is inserted into the machine on the s~me side from which the wound roll was ejected, it is partly encircled by the strip of material, which allows the start of the strip produced after severing to be held and facilitates the attachment thereof to the winding sleeve. It is preferable for the strip of material to be glued, lmmediately after the severing operation, gradually to the winding sleeve.
The method according to the invention may be carried out with relatively simple means, somewhat like the sleeve inserting and attachment device disclosed in German O~ 27 09 684.
The method of operation of the wound roll wlnding sleeve changing device is explained here~nafter in greater detail in conjunction with the different operating stages shown in Figures 1 to 5.

Ejection-beam 1, including cutting device 2, is adapted to pivot about the axis of carrier roll 3 by means of two levers 4 which are united by means o~ a rotationally rigid transverse member 5. Levers 4 comprise guides 6 along which beam 1 is displaceable, at right angles to the axis o~ carrier roll 3, by means of a motor 7. Cutting device 2 also moves along guides 8 on beam 1, but in the axial direction of carrier roll 3.
The second component of the automatic changer ls sleeve injector 9, which consists mainly of two levers 11 adapted to pivot about the axis of carrier roll 10, the said levers being united by means of a rotationally ri~id transverse member 12.
The said member accommodates insertion channels 14 adapted to hold interchangeable winding sleeves of different diameters.
The means for securing strip o~ material 18 to winding sleeve 13 are not shown in the drawing. The said means may be in the form of an attaching device also arranged on ejection beam 1, or of a device whic~ applies an adhesive strip by means of which the strip of material 18 is ~lued to ~inding sleeve 13, In this case, the adhesive device may be coupled to the cutting device, thus moving jointly there~ith~
Figure 1 shows the starting-position prior to the change, over.
As shown in Figure 2, wound roll 15 has been e~ected from the carrier roll bed by a pivoting moti~n of levers 4 in the direction of arrow 16, and has been t~ansferred to a lowering platform 17. Strip of material 18 is drawn back. ~fter reaching the forward terminal position (Figu~e 2), ejection beam 1 ~ay be . ~ 4 --~`~6~S
pre-adjusted to any desired sleeve diameter by moving it along guides 6.
Ejection beam 1 with cutting device 2 is then removed from the carrier roll bed by pivoting levers 4 back in the direction of arrow 21 (Figure 3). Some slack is now imparted to the strip of material, for example by easing up on the brake or by lowering platform 17 slightly. ~inding sleeve 13 is inserted into the carrier roll bed by pivoting levers 11 (Figure 3).
Strip of material 18 now lies around a part of the periphery of the said winding sleeve.
As shown in Figure 4, levers 11 of sleeve inserting device 9 are pivoted back in the di~ection o~ arrow 19~ while cutting device 2 is pivoted back again in the direction of arrow 16, thus occupying a position above the strip of material on the upper surface of w~inding sleeve 13. In this position, the said strip is severed by cutter 20 and is giued to winding sleeve 13.
Cutting device 2 may then be pi~oted back, with ejection beam 1, in the direction o~ arrow 21, into the starting position shown in Figure 5 and Figure 1~ Pressure roll 2 is lowered onto winding sleeve 13 and the winding process may now be continued.
