Definitions
- the invention relates to a device for severing a material web, in particular a paper or cardboard web, on the support or support roller of a winding machine according to the preamble of patent claim 1.
- a carrier roll winding machine in which the cutting of the web is carried out by means of a separating device moving up through the carrier roll nip, at the tear-off blade of which the web breaks when the full winding rolls are ejected.
- the newly created beginnings of the web are held by means of negative pressure on the support roller designed as a suction roller until new winding sleeves are inserted. It is not necessary to reposition the start of the web for winding.
- This advantageous separating device cannot be used in support roller winding machines in which the winding rollers lie on a support roller on both sides of the apex line when winding along two winding lines, since the full winding rollers of the two winding lines are removed from the machine in opposite directions - in and against the web running direction .
- a generic device is therefore proposed in DE-OS 36 11 895, in which a scraper in the looped area of the backing roll can be placed on the web and moved transversely to the web running direction.
- the cutting edge of the separating scraper is designed as a saw and cuts through the web when moving transversely to the web running direction.
- the invention has for its object to improve a generic device so that it is structurally simple to safely cut the web when changing roles.
- a rotatable, circumferentially sharp wheel is used as a separating device, with which the web can be severed or at least weakened to such an extent that it tears through the increased web tension when the winding rollers are raised or lowered for unloading.
- the resilient support limits the maximum contact pressure so that damage to the roller surface is avoided.
- the embodiment according to claim 4 contains a structurally particularly advantageous drive of the wheel for the transverse movement.
- Claims 5 and 6 claim winding machines using the separating device according to the invention, wherein the inflatable clamping hose according to claim 6 prevents a disruptive propagation of the increased web tension when the web is severed by increasing the web tension.
- Fig. 1 shows a partial side view
- Fig. 2 shows an enlarged section of Fig. 1 and
- FIG. 3 shows a plan view in the direction of arrow "Y" in FIG. 2.
- the section shown in Fig. 1 in side view winding machine has a support roller 1 designed as a suction roller, on which the winding rollers 2, 3 during winding up on the web 4 - a paper or cardboard web - rest.
- the winding rolls 2, 3 are each held by guide heads 5, 6 which can be inserted laterally into the winding sleeves.
- the web 4 is divided into several individual webs by slitting, alternately the one on either side of the apex line of the support roller 1 Arranged arranged winding lines and wound up there to winding rolls 2, 3 aligned.
- Two lowering platforms 7, 8 are used to remove the winding rolls 2, 3 from the machine, each of which can be raised to the underside of the winding rolls 2, 3 by means of piston-cylinder units 9.
- the lowering platforms 7, 8 are lowered, and the winding rollers 2, 3 are transported away.
- the lowering platform 7 on the inlet side is only shown in part in FIG. 1.
- a piston rodless, pneumatic piston-cylinder unit 11 extending over the entire working width is fastened.
- a plate 13 is screwed, on the side facing the support roller 1, a short lever 14 is articulated.
- the lever 14 has a bearing eye 15 which can be clamped to the plate 13 by means of a screw 16 in order to fix the angle of attack to the support roller 1.
- the free end of the lever 14 is fitted into a helical spring 17 and firmly wedged with it.
- a pin 18 is wedged, which is extended at the end in the shape of a fork.
- a wheel 19 made of hard metal or hardened tool steel with a circumferential sharp cutting edge is freely rotatably mounted in the manner of a glass cutter.
- the wheel 19 has a diameter of approximately 5 mm. So that it rolls across the web 4 supported by the support roller 1 when moving transversely to the web running direction, its axis of rotation is perpendicular to the support roller axis. When pivoting the lowering platform 8 in the direction of the support roller 1, the wheel 19 is pressed against the web 4 resting on the support roller 1.
- the part of the spring 17 holding the pin 18 bends when placed on the track 4, so that the wheel 19 is pressed against the track 4 by the spring 17.
- the lowering platform 8 is pivoted so far that an angle between the axis of the pin 18 and the surface line of the support roller 1 is set in the working position, which is between 15 ° and 35 °.
- the pin 18 is thereby inclined against the direction of movement (arrow 20), so that the wheel 19 is pulled over the web 4 during movement.
- a support plate 21 is attached to the lowering platform 8, on the side facing the support roller 1, an inflatable clamping hose 22 corresponding to the working width is clamped.
- the clamping hose 22 expands when inflated between the support roller 1 and the support plate 21 and thus clamps the web 4 on the support roller 1.
- the support roller 1 is stopped and the web 4 is held on the support roller 1 by means of suction air.
- the lowering platforms 7, 8 are raised - shown in broken lines in FIG. 1 - the separating device 10 integrated in the lowering platform 8 is thus brought into the working position shown in FIGS. 2 and 3.
- the wheel 19 is pressed by the spring 17 against the web 4 resting on the support roller 1.
- the clamping hose 22 is inflated to hold the web 4 in addition to the suction air during the separation process.
- the piston-cylinder unit 11 moves the pressed wheel 19 across the entire width of the web.
- the 'web 4 is or weakened, depending on their thickness either completely severed.
- the lowering platform 8 is positioned at a short distance below the winding rollers 3 for unloading. After loosening the guide heads 6, the winding rollers 3 roll a short distance over the lowering platform 8 and rotate in the direction of arrow 23 (FIG. 1). The increase in web tension resulting from the rotation cuts through the individual webs wound on the exit side.
- the inflated clamping hose 22 prevents the web tension increase from propagating into the longitudinal cutting device arranged below the support roller 1 _.
