Definitions
- the invention relates to a strand guiding device according to the preamble of claim 1 or 15.
- Devices of this type come e.g. B. in rotary printing machines at the entrance of a folder to use to bundle several printed paper webs into a strand and to feed a former.
- devices with two driven rollers are used for guiding strands, between which the strand extends in an S-shape and each wraps around a part of its circumference.
- a web that is on the outside of a first of the rollers and experiences only a relatively weak driving force from the roller becomes the inner web on the second roller, and vice versa.
- the sum of the driving forces that act on each individual web from the two rollers can therefore be made more uniform than if only a single roller is used.
- DE-PS 682295 shows an S-shaped web guide between two rollers, one roller being stationary and the other roller being pivotable about the stationary roller.
- DE 37 13915 A1 and DE 1 038394 B describe electrical regulating devices for regulating the tensile force in a winding material. Two S-shaped rollers are used as the measuring element.
- DE 1 286367 B discloses a device for regulating the winding tension of a web-like material, in which two S-shaped rolls are present. A position of a pivotable roller is controlled in such a way that its wrap angle remains constant.
- DE 3534846 C2 discloses a device for compensating for different path movements. A distance between one guide roller and two other guide rollers is adjusted as a function of a speed difference.
- the invention has for its object to provide a strand guide device.
- the strand guiding device enables the guidance of a multi-layer strand with little slip between the layers of the strand, regardless of a possible torque regulation of the individual rollers. Because one of the rollers is made adjustable relative to the other in an adjustment direction that extends obliquely to a running plane of the strand extending between the rollers, the circumferential angles on which the two rollers are each wrapped by the strand can be changed in opposite directions, so as to vary the distribution of a driving force over the two outer layers of the strand as required.
- One of the rollers here referred to as the second roller, preferably has a fixed axis, and the first roller can be pivoted about the axis of the second.
- the swiveling movement enables the angles around the strand to be changed at the same time on both rollers and thus to regulate the total driving force transmitted to the strand from both rollers.
- Adjustment means for pivoting the first roller about the axis of the second are preferably elastically displaceable under a force acting in their direction of adjustment.
- the strand guiding device can yield to a fluctuating tension of the guided strand by an evasive pivoting movement of the first roller, which at the same time reduces the wrap and thus the driving force exerted is reduced.
- a pneumatic cylinder is particularly suitable as such an elastic adjusting means.
- the first adjusting means for adjusting the rollers relative to one another are preferably rigid under a force acting in their direction of adjustment.
- Such an adjusting means can be implemented in a simple manner with a rotatable threaded spindle.
- the first actuating means can in particular comprise two actuators which can be set independently of one another, so that the axis of the first threaded spindle can also be set non-parallel to the axis of the second. Such a non-parallel position may be necessary for an exact strand guidance if the strand is composed of layers of different widths, so that the number of layers on one side edge of the strand is different than on the opposite side edge.
- the position of this fixed point determines the extent of the wrap angle change, which is in each case associated with an adjustment of the first and / or second actuators.
- An adjustment of the first roller by the first adjusting means generally causes a change in the angle at which the strand wraps around the first roller. However, if a line is specified along which the actuating movement of the first roller takes place, there is always a point on this line at which, if the axis of the first roller is located there, the looping of the first roller reaches a minimum. In order to be able to effectively vary the ratio of the contributions of the two rollers to the total driving force acting on the strand in the course of an actuating movement, it is expedient if an adjustment area of the first actuating means extends on both sides of this minimum position.
- the fixed point is preferably designed as a third roller.
- the strand guiding device can be arranged at a single entrance of a former, it can also extend over the entrances of several neighboring former.
- each folding former is preferably assigned its own second roller, which is adjustable independently of the second rollers of other folding former.
- Figure 1 is a side view of a strand guide device.
- Fig. 2 is a diagram of the strand guide device, which illustrates the determination of the placement of the rollers and their ranges of movement;
- FIG. 3 shows a perspective view of the strand guiding device from FIG. 1;
- Fig. 4 is a perspective view of a second embodiment of the strand guide device.
- the strand guide device shown in perspective in FIG. 1 and in FIG. 3 is arranged between a turning bar arrangement, not shown, and a folder of a web printing press.
- a plurality of material webs 02 e.g. B. paper webs 02, which come from the turning bars, meet on a second roller 01, where they are deflected and unite to form a strand 03 of superimposed paper webs 02.
- the roller 01 is rotatably driven by a motor 04 around a shaft which is stationary with respect to a frame of the guide device (not shown).
- Two levers 06 are pivotable about the same shaft, each being arranged on the shaft at the axial ends of the roller 01, only one of which can be seen in FIGS. 1 and 3.
- an adjusting means 08 e.g. B. a piston rod of a pneumatic cylinder 08, the housing of which is pivotable about a fixed point on the frame.
- the pneumatic cylinder 08 thus holds the lever 06 in a given position, but is compressible or expandable under the action of a torque acting on the lever 06.
- a sliding block 11 On a second arm 09 of the lever 06, a sliding block 11 is held displaceably in the direction of the arm 09.
- the sliding block 11 carries on the one hand a shaft of another, also driven by a motor 04 first roller 12 and on the other hand is in engagement with an adjusting means 13, e.g. B. a threaded spindle 13, which by a mounted on the second arm 09 adjusting means 14, z. B. actuator 14 is rotatably driven to move the roller 12 along the arm 09.
- the strand 03 wraps around the rollers 01; 12 on different sides and finally reaches a fixed point 16, z.
- the roller 16 in turn has a fixed shaft.
- Motion sensors for detecting a possible slippage between the paper webs 02 of the strand 03 can be arranged at different points along the path of the strand 03.
- sensors in the form of rotary encoders are each arranged on the roller 16 and a roller 17 which is positioned against the roller 16 and forms a gap with the roller through which the strand 03 runs.
- the roller 16 forms the entrance of a folding former 27, on the bottom of which a pair of cutting rollers 28 is arranged for the disassembly of the strand 03 into individual products.
- a section 18 of the strand 03 extends between the rollers 01; 12 obliquely to the second arm 09.
- the wrap angle ⁇ , on which the strand 03 wraps around the roller 01, is therefore greater for a given orientation of the arm 09, the smaller the distance between the two rollers 01; 12 is.
- the wrap angle ⁇ of the strand 03 on the roller 12 changes only insignificantly when the roller 12 is displaced along the arm 09, since each time the roller 12 is displaced along the arm 09, the point 19 at which the strand 03 with the roller 12 comes into contact, and point 21, at which they separate again, migrate in the same direction and to approximately the same extent.
- the tension of the string 03 can vary due to irregularities in running. If the tension increases, an increasing torque acts on the roller 12 to the right in FIG. 1, as a result of the pneumatic cylinder 08 being compressed and the roller 12 deflecting to the right along the curved arrow A in FIG. 1. This simultaneously reduces the path length of the strand 03 between the rollers 01 and 16, the tension decreases, and as a result of a reduction in the wrap angle ⁇ ; ß also increases the driving force of the rollers 01; 12, with the result that such voltage peaks are difficult to damage the Can guide paper web 02 and are soon dissipated by the strand guiding device.
- Fig. 2 shows a highly schematic representation of the strand guide device, in which the rollers 01; 12; 16 are each reduced to break points on the path of line 03.
- the paper web course shown in FIG. 1 is shown in FIG. 2 as a solid line; a double arrow 22 represents the direction of displacement of the roller 12 along the second lever arm 09. Further possible positions of the roller 12 along the arm 09 or the resulting courses of the strand 03 between the rollers 01 and 16 are shown as dashed or dash-dotted lines 23; 24 shown.
- a dotted imaginary circular arc 26 connects the three rollers 01; 12; 16 when the roller 12 is in the position shown by the broken line 23.
- the wrap angle ⁇ on the roller 12 reaches a minimum if, as in the case of the line 23, it is at the location where the circular arc 26 and the double arrow 22 touch; in the vicinity of this position the dependence of the wrap angle ⁇ on the position along the double arrow 22 is small and increases both upwards and downwards when displaced. In the vicinity of this point, the ratio of the wrap angles ⁇ / ⁇ changes strongly with the position of the roller 12, so that the relative proportions of the rollers 01; 12 to the total driving force acting on the strand 03 is possible.
- FIG. 4 shows a perspective view of a second embodiment of the strand guiding device. It comprises stationary rollers 01; 16, which each extend over the entire width of three adjacent formers 27. Three rollers 12 can be pivoted independently of one another on two levers 06 suspended. Each of the three rollers 12 leads together with the rollers 01; 16 one of three strands 03 to one of the folding former 27. Corresponding to different numbers of paper webs 02 combined in the strands 03, each of these rollers 12 can be adjusted to a suitable distance from the roller 01 independently of the other rollers 12 and can be tensioned differently by the strands 03, as shown in FIG. 4, can be pivoted to different degrees about the axis of the roller 01.
