Definitions
- the invention relates to a folding cylinder according to the preamble of claim 1.
- Such folding cylinders with an adjustable scope are z. B. from US 58 46 177 A and DE 295 02 957 U1, DE 38 21 442 C2 and US 53 13 883 A known.
- Such folding cylinders comprise a plurality of flexible bands which are held at at least two locations on the body of the folding cylinder, at least a first of these locations being displaceable in the circumferential direction of the folding cylinder.
- a central region of the strips can be spread apart from the body of the folding cylinder and thus its circumference can be increased to an extent corresponding to the displacement of the first points.
- DE-AS 16 11 330 discloses a circumferentially adjustable folding cylinder, with several belts being adjusted by means of a common drive chain.
- the invention has for its object to provide a folding cylinder, the scope of which can be adapted to the processing of different products.
- the circumference of the folding cylinder can be adjusted to adapt to the processing of products of different lengths and to adapt paper paths / web tension that vary due to the thickness of a product.
- folding cylinder An important advantage of the folding cylinder is that it enables identical adjustment displacements of several strips of different groups to be realized on the folding cylinder without the need for a complex coupling mechanism that rotates with the folding cylinder.
- the stop ring against which the bar is pressed is stationary on a folder, and a head portion of the bar is movable along the surface of the stop ring.
- Such a movable head section is preferably formed by a wheel rotatably held on the bar.
- the stop ring can be rotated with the body of the folding cylinder and thus also together with the strips.
- the stop ring can easily be part, especially one Bearing disc, an axial roller bearing can be formed, wherein the respective other bearing disc of the axial roller bearing can be held stationary on a side frame supporting the folding cylinder.
- Figure 1 is a perspective view of a folding cylinder with an adjustable circumference.
- Fig. 2 is an exploded perspective view of a flexible holder
- Fig. 4 is a schematic representation of the mechanism for circumferential adjustment according to a second embodiment of the invention.
- each of flexible bands 02 is arranged at an angular distance of 120 ° in the circumferential direction, two of which can be seen in FIG. 1.
- Each of these groups is assigned a bar which can be moved parallel to the axis of the folding cylinder 01 and whose function is explained in more detail.
- the bands 02 each delimit a plurality of slots 03 between them.
- the folding knife is attached to a so-called Spider 06. This spider 06, which is only partially visible in FIG.
- the bands 02 are each at two points 11; 12, e.g. B. two longitudinal ends 11; 12 held on the body of the folding cylinder 01. From these longitudinal ends 11; 12 is one, designated by 11 in FIG. 1, immovable on the body of the folding cylinder 01, and the other longitudinal end 12 is displaceable in the circumferential direction of the folding cylinder 01.
- the displaceable suspension of the longitudinal end 12 of one of the bands 02 is shown in FIG. 2 in a detailed, exploded view.
- the band 02 runs out at its longitudinal end 12 in two tongues 13, which are wound around a cylindrical pin 14.
- the pin 14 is provided to be between two clamping bodies 16; 17 to be pinched. It is also conceivable that the pin 14 is inserted laterally into a bore and fixed with the aid of a screw.
- the clamping body 16; 17 are connected by rivets (not shown) or other suitable means to form a unit called a sliding block.
- the pin 14 is held firmly in the sliding block, the longitudinal end 12 of the band 02 is pivotable with respect to the sliding block.
- an elongated cutout or depression 18 is formed in the longitudinal direction of the band 02.
- a through hole 19 is also elongated in the longitudinal direction of the band 02.
- a means 21, e.g. B. a pin 21 has a threaded shaft 22 which is provided to be inserted through the hole 19 and an inserted into the recess 18, perforated plate 23 and tightened with the aid of a nut 24.
- the extension of the plate 23 in the longitudinal direction of the band 02 is slightly smaller than that of the recess 18, so that the pin 21, if it is not tightened, can be displaced somewhat in the longitudinal direction of the band 02.
- a flange 26 adjoins the threaded shaft 22 of the pin 21, which is tightened State of the pin 21 presses against the underside of the clamping body 17. Below the flange 26, the pin 21 is extended by a shaft section on which a roller 27, held between the flange 26 and a head 28 of the pin 21, is freely rotatable.
- a rigid strut 32 which is fixed on the body of the folding cylinder 01, extends at regular intervals on its outside, which is at the top in FIG. 2, and short guide rails 33 which extend in the circumferential direction of the folding cylinder 01 and one pair each Guide the sliding block so that it can move in the circumferential direction.
- FIG. 3 shows a schematic illustration of a first mechanism for controlling the position of the strip 31 assigned to each group of bands 02.
- a spring 34 exerts a force on the strip 31 which is directed to the right in the illustration of FIG. 3 and which is a head portion of the Holds bar 31 against a stop ring 37, which is mounted on a side frame plate 36 of the folder concentrically to the folding cylinder 01 but not rotatably with it. Furthermore, it is conceivable that the spring 34 is dispensed with, since the tension of band 02 generates a sufficient axial force by means of the slant of slot 29.
- a wheel 38 is rotatably held on the head section and rolls on the surface of the stop ring 37 when the folding cylinder 01 rotates. Since this surface is oriented exactly perpendicular to the axis of the folding cylinder 01, the rotational movement of the folding cylinder 01 does not cause any axial displacement of the bar 31. Such a displacement only comes about when the stop ring 37 is displaced as a whole parallel to the axis of the folding cylinder 01. Such a displacement of the stop ring 37 causes identical displacements of the strips 31 of all groups of bands 02 and thus the same changes in the curvature on the bands 02 of all groups.
- FIG. 3 The mechanism illustrated by way of example in FIG. 3 comprises a plurality of threaded spindles 42, only one of which is shown in FIG. 3.
- a thread-free section of the threaded spindles 42 is rotatably mounted in the side frame plate 36 and is not axially displaceable.
- a threaded section of each threaded spindle 42 is in engagement with a threaded bore 43 of the stop ring 37.
- the threaded spindles 42 are coupled via a toothed belt 44, which engages with gear wheels 46 fastened to each threaded spindle 42. Since the axes of the threaded spindles 42 are stationary, their rotational movement can be driven in a simple manner as indicated by a crank 47 or a servomotor which acts directly on one of the threaded spindles 42.
- a first ring 39 of an axial bearing coaxial with the folding cylinder 01 serves as a stop ring 39, against which the head section of each strip 31 is pressed by the spring 34.
- This first ring 39 can be rotated together with the folding cylinder 01 by frictional contact with the head sections of the strips 31;
- a second ring 41 of the axial bearing is connected to the side frame plate 36 of the folder in a rotationally fixed and axially displaceable manner.
- An axial displacement of the second ring 41 drives the same displacements of the strips 31 and thus the same deflections of the groups of strips 02 via the first ring 39.
- the same mechanism with coupled threaded spindles 42 as described above with reference to FIG. 3 can be used to drive the displacement of the second ring 41.
