> Winding machine for tape material

¹ Bie invention relates to a winding machine for web material JMIT more about a common pivot axis pivotable! Individually drivable package receivers, with a winding station, a transverse cutting device and with a changing station.

Such a winding machine is used to manufacture iWindles from the most varied of strip material, from paper webs, iAdhesive foils, metal foils, each in simple or laminated! state. In a known winding machine, the winding 'recordings are arranged in the form of a two-star or three-star. 'From the geometry of this winding star it follows that the ! Different stations in the two-star diametrically, i.e. at the distance of the star's diameter, with the three-star under one ! mutual angular displacement of 120 each be arranged j have to. This primarily requires a large amount of space, because the mutual distance between the various processing stations is great. Because separately or in combination with the jA change station normally has to be provided with additional stations, in particular a loading station and, if necessary, one Gluing station. The station distances are determined solely by the Geometry of the respective center star established so that an [adaptation of the various assemblies, such as cross cutters, changing devices, Gluing devices and the like. On different roll diameters or different diameters ! the winding cores is not possible or only possible with great effort. The respective cutting of the web end takes place in the winding station, from where the cut end of the web to the changing station

j runs freely, where the respective full lap I is completely wound. In known winding machines, the cut runs ι end of the track unguided over a comparatively large distance, namely in each case over the distance caused by the geometry of the winding star ! the specified distance between the wrapping station and the j changing station. This leads to errors when the respective web end is picked up on the full lap.

I object of the invention is one embodiment of a winding-machine I that the same even at different employment ^services: ratios, in particular, allows each Wickeldurchmessein optimum web guide. The overall space requirement is to be reduced.

j This object is achieved according to the invention in that each j The winding shaft is seated on a separate swivel bracket and that the various swivel brackets move independently of one another into the Winding station, changing station and possibly other processing stations are pivotable.

By means of such separate pivoting supports, it is now possible to arrange the individual processing stations as they are this is most favorable for the tape run. You are no longer on the geometry when defining the machining stations a winding star. You can see the actual winding station and the changing station in which the full Winding is finished after cutting off the end of the tape, arrange at a small mutual angular distance so that the cut end of the web is only unguided over a short distance. The angular position of the respective lap holder in the changing station in relation to the winding station can vary according to the respective winding diameter to get voted. This results in essentially the same guidance of the web end from the deflection and / or in each case Pressure roller over the winding tube in the winding receptacle to the winding tube in the changing station. This is for that Operation of the cross cutter and the fastening of the beginning of the web

sit winding fixtures 4, which with the help of rail guides! j can be adapted to the respective winding width. The wrap 4 The holders also contain the friction elements for driving the winding sleeves. The winding receptacles 4 each take winding j ! Sleeves 5 in a known manner. j

The winding machine according to the invention comprises a winding station j6, to which a deflection and / or pressure roller 7 belongs, which jan pendulum arms can be pivoted about a shaft 8, so that the deflection and pressure roller 7 between the positions 7 and 7 ^f ι corresponding to the increasing winding thickness can be adjusted so that a uniform winding strength is obtained. In addition, a transverse cutting device 9 is assigned to the winding station, which comprises a fly knife bridge 11 mounted on pivot arms 10. The pivot arms 10 each enable the cross-cutting device to be set to different diameters of the winding tube. The fly knife bridge 11 is also equipped with a pressure device 12 for the respective cut-off strip beginning.

I further comprising the winding machine according to the invention, a i j changing station 13, in which a package receiver 4 each unmittelj ^j 'bar can be moved before cutting of the strip end. \ The position of the winding sleeve 5 in the change station 13 is in each case! Selected depending substantially between the positions 5 and 5 'of the winding diameter, so that the path I14 runs of the tape end are substantially equal. Following the changing station is a loading station 15 and a ^; Gluing station 16 is provided, each of which is constructed in a manner known per se.

; The winding machine according to the invention enables a very ; favorable operating behavior. Everyone's education j Tape winding takes place in the winding station 6 with the help of the deflection I and pressure roller 7. The lap holder 4 can almost completely fill a tape lap in this winding station! 6 remain so that you can get a very even winding. When the wrap is almost full, there is « the deflection and pressure roller in position 7 '. Now j the lap holder 4 is pivoted into the changing station 13, i where the tape runs substantially on track 14. At the same time, a winding receptacle 4 with an empty winding tube j j 5 swiveled into the winding station 6. The deflection and pressure j I roll is returned to position 7. The fly knife bridge 11 is triggered, so that the tape immediately - in the vicinity of the j i the catch area of the winding tube 5 is severed. The pressure! Device 12 presses the severed beginning of the web onto the winding tube 5. The tail of the web moves freely on the web 14, which extends over a comparatively small circumferential arc, so that there are no major difficulties in guiding the end of the tape. In the figure, on the one hand, the position of the winding tube 5 in the changing station 13 for a large Winding diameter and on the other hand a position of the winding tube 5 'for a comparatively small winding diameter drawn. The angular position of the winding tube and thus the winding receptacle 4 is in each case depending on the desired Winding diameter chosen so that the web 14 of the

Tape that runs tangentially on the roll, maintains the same iLage in relation to the winding station 6, so that the ■ Cross cutting device 9 and the deflection guide around the roll i are effective in a favorable working situation.

: In the winding station 13, after the end of the tape has been cut off, the tape lap is completely wound, whereupon the winding tube runs out. The full roll is removed and the roll holder j 4 is moved further into the position shown in dash-dotted lines ^! 4 'pivoted in the loading station, where an empty winding tube is automatically fed. An empty winding tube can also be fed by hand if necessary. The manner in which a winding tube is fed into the loading station is not the subject of the invention. The lap holder with the empty one

! Winding tube then moves further into the position 4 ^r 'in! The gluing station 16 where necessary, a glue application j is carried out for the determination of the rewinding. Such gluing is not necessary, for example, when using the winding machine for self-adhesive tapes. From the gluing station, the cradle holder with the empty reel tube is finally pivoted into the reeling station 6, essentially simultaneously with the pivoting of a reel receptacle with a full reel into the changing station.

• The winding receptacle 4 is in each case during a comparative large part of the respective cycle time in the winding station, so that the tape roll is essentially completely mitjhilfe the deflection and pressure roller 7 can be finished. ! During this winding time, the other person can take up the winding 4 in the required manner by the other processing stations are moved, the respective dwell time can be optimally adapted to the various machining operations. This means for the construction of the individual processing stations a significant simplification because these j processing stations only take into account the J special conditions can be designed in the individual stations

i have to. It is particularly important that the winding station and the changing station come comparatively close to one another. ! This distance is limited essentially only by the maximum l roll thickness and not by the radial length of the l roll holder. In addition, the position of the lap holder in the changing station can be determined differently for different lap diameters, which is favorable for guiding the cut bend 3ndes.
