Definitions

  • the invention relates to a device for position control of a running web transverse to the running direction.
  • "Running web” is to be understood in general to mean any type of goods as they are processed as semi-finished products or in a production intermediate step as web goods, such as Plastic films, plastic bags, magazines, synthetic leather, paper webs in the production of corrugated cardboard etc.
  • this term is also intended to include endlessly circulating tapes, such as those e.g. can be used as a so-called “screen” or "felt belt” in paper machines or as a conveyor belt in conveyor technology.
  • So-called web guider in various embodiments are known from the prior art.
  • So-called rotating frames are used, in which two guide rollers arranged parallel and at a distance from one another in the web running direction are arranged on a frame which can be rotated about a vertical axis by a corresponding actuator, for example in the form of a pneumatic cylinder.
  • the two guide rollers can be placed slightly obliquely to the web running direction in a horizontal plane, so that the web running over the guide rollers is given a corresponding transverse offset.
  • the transverse position of the web can be continuously corrected by regulating the rotating frame position.
  • a web guiding system for the straight-line control of endless belts such as conveyor belts and sieve belts made of different materials, e.g. Plastic, rubber, metal mesh, textile, etc. used, which uses a tape guide roller with an actuator, counter bearing and mechanical scanning by means of a roller lever.
  • the tape guide roller can be pivoted with its bearing journal on one side in the counter bearing and on the other side in a combination bearing in a rotationally sliding manner.
  • the combination bearing is in turn attached to an actuator arranged on the side of the belt to be guided, with which the belt guide roller can be pivoted on the other side about the counter bearing forming its pivot point.
  • the swivel movement is regulated by the mechanical scanning of the web edge.
  • the guide roller is equipped with a special self-aligning bearing.
  • This has a fixed center tube, which has an approximately vertical bolt in the middle.
  • This pin forms a pendulum axis around which a shorter piece of pipe can swing back and forth in the horizontal.
  • This tube piece carries ball bearings at both ends, around which an outer jacket tube made of glass fiber reinforced polyester can rotate.
  • This jacket tube forms the actual guide roller.
  • a disadvantage of the known guide roller is the fact that the self-aligning bearing is arranged relatively hidden in the interior of the casing tube and is therefore difficult to assemble.
  • the force resulting from the described bearing behavior is concentrated on the center of the load-bearing central tube, so that the roller must have very large diameters for larger working widths for reasons of stability.
  • this guide roller there is no possibility of additionally providing an active position control if the response speed of the automatic control is not sufficient for the respective application.
  • the invention has for its object to provide a device for position control of a running web transverse to the direction of travel, which is automatically effective with high responsiveness, but can also be coupled to an active position control and also requires less installation effort .
  • At least one pendulum roller is provided in the device, via which the web to be regulated in its transverse position is guided over a wrap angle and which has a rotating jacket.
  • the jacket is supported by two rotary bearings at two symmetrical points on the jacket tube, in particular at the two roller ends, on an inner counter bearing part which is not rotatable with respect to the axis of rotation R of the roller jacket.
  • This counter bearing part which can be, for example, a pipe or a rod, is in turn mounted directly or by means of a lever system symmetrically and articulated via pendulum joint elements, the two pendulum joint elements being arranged diametrically opposite one another with a radial distance from the axis of rotation.
  • the two pendulum-joint elements thus define an inclined pendulum axis for the pendulum roller, which intersects the axis of rotation at an acute angle in the center of gravity of the roller and runs in a plane which, with a vertical plane lying transversely to the direction of web travel, forms an acute angle that opens in the direction of web travel includes.
  • the plane receiving the pendulum axis is thus tilted in the direction of web travel, which is an important feature for the function of web guiding.
  • the pendulum axis intersects the plane spanned by the axes of rotation of the rollers in their common center of gravity.
  • the axis of symmetry of the continuous counter-bearing part also coincides with the axis of rotation of the roller or, in the case of several rollers, lies in the plane formed by the roller axes and is parallel to the roller axes.
  • the pendulum roller is in an indifferent equilibrium as long as the web to be guided runs symmetrically over the pendulum roller. As soon as this runs out of its desired position, the pendulum roller is loaded unevenly and tilts about the tilting pendulum axis, so that it is swung out of its horizontal position and the belt is returned to the equilibrium position. As has been determined by practical tests, the side of the pendulum roller, towards which the web to be guided runs out in the transverse direction, dips. Because of this tipping, the web runs virtually up the pendulum roller, so that the web is returned to the center and the pendulum roller is straightened.
  • An advantage of the strip guiding system according to the invention is the fact that the rotary bearings are located on both roller ends, so that the assembly effort is greatly reduced.
  • the "double pendulum bearing" which is essential to the invention, ensures highly effective automatic web guiding by means of two diametrically opposed pendulum joint elements for defining an inclined pendulum axis.
  • this is designed in such a way that an active position control can be coupled with a conventional position sensor for the transverse position of the web to be controlled, a control device connected to the position sensor and an actuator controlled thereby.
  • the latter can directly access the counter bearing part for the pendulum adjustment of the pendulum roller, since this counter bearing part is in the area of the roller ends - so it is practical freely accessible - lies. This is an important differentiator from the "servo roll" discussed above.
  • the non-rotatable linkage of elements from the counter bearing part and possibly a lever system is a rigid structure which serves as a carrier for the one or more pendulum rollers.
  • This inherently rigid structure is connected to the pendulum roller by the indicated pendulum joint elements.
  • a pendulum roller 1 with a roller shell 2 is provided, at the two longitudinal ends of which rotary bearings in the form of ball bearings 3, 4 are provided.
  • these ball bearings 3, 4 can also absorb axial forces.
  • the counter-bearing part for the ball bearings 3, 4, which is stationary with respect to the rotational movement, is each formed by a common continuous bearing tube 5, which in turn is at its ends 6, 6 'in each case functionally as a ball joint 7, 8 designed, symbolically drawn pendulum joint element is articulated.
  • the stationary counter bearing part 9, 10 of the two ball joints 7, 8 sits on radial struts 11, 12, which in turn are arranged on a machine-fixed main bearing.
  • the latter in the embodiment according to FIG. 1 is a continuous axle strut 13 which is mounted on two schematically indicated bearing frames 14, 15 of the machine frame.
  • the main bearing is formed by two coaxial stub axles 16, 17, which in turn are fastened to the bearing frames 14, 15.
  • the two radial struts 11, 12 run in diametrically opposite directions and are inclined at an angle B to the vertical.
  • Their radial distance “e” from the axis of rotation R of the pendulum roller 1 can be 30 to 100 mm. The bigger “e” is, the higher the sensitivity of the self-regulation described in more detail below.
  • the two central points M and N of the ball joints 7, 8 which form the pendulum joint elements define an oblique pendulum axis Q which intersects the axis of rotation R in the roller center of gravity W at an acute angle A and extends in a plane X which is perpendicular to the web running direction B ' Y includes the aforementioned acute angle B, which opens in the web running direction B '.
  • the plane X is thus tilted in the web running direction B ', as is clear from FIG. 3.
  • the web 18 to be regulated in its transverse position is guided over the pendulum roller 1 with a matching entry and exit angle C, so that a wrap angle U of 2 C results.
  • the web 18 (dash-dotted lines in Fig. 1 and 2) is arranged in the center, so that the left and right of the plane of symmetry S are the sections Lb1 and Lb2 of the sheet width Lb to match.
  • the automatic web guiding function of the pendulum roller 1 can be briefly described as follows:
  • a lever arm 19 can be attached to the bearing tube 5 at the end 6, which lever arm is used to engage an active control device for the web transverse position, which will be explained later.
  • a concrete constructive embodiment of the pendulum roller shown schematically in Fig. 1 is shown, wherein in Fig. 4 is indicated by dash-dotted lines that the pendulum roller 1 is used to regulate the transverse position of a rotating belt 20, in which it is, for example can be a pressure belt in a corrugated cardboard machine.
  • the latter is guided around two deflection rollers 21, 22.
  • the upper run 23 of the belt 20 is guided over the pendulum roller 1.
  • the radial struts 11, 12 are also attached to a sleeve part 25, 26 which sits on the axle strut 13 in a rotationally fixed manner (rotation lock 27).
  • the latter has a central tube 28 which takes up almost the entire length of the oscillating roller 1, in the ends of which cylindrical, stepped pins 29 are inserted, each of which receives the sleeve parts 25, 26.
  • the axle strut 13 is screwed to the end of the bearing frame 14, 15 (screws 30).
  • the device shown in FIGS. 4 to 6 is also provided with an active position control, which acts on the lever arm 19.
  • this active position control has a position sensor 31 which is arranged in front of the pendulum roller 1 in the web running direction B 'and which is, for example, an electro-optical or pneumatic edge sensor can act as it is known from the prior art.
  • FIG. 7 differs from the embodiment according to FIGS. 4 to 6 essentially only in the configuration of the main bearing.
  • This is formed here analogously to FIGS. 2 and 3 by stub axles 16, 17 screwed to the bearing frame 14, 15, to which the radial struts 11, 12 for the pendulum joint elements 7, 8 are integrally formed. Otherwise, identical structural parts are again provided with identical reference numerals and do not need to be discussed again.
  • each of the holding struts 38, 39 is in turn mounted via a ball joint 7, 8 as a pendulum joint element, whose stationary counter bearing part 41, 42 is attached to a bearing frame 14, 15.
  • the one strut 38 is provided with an extension piece 43 acting as a lever arm, on which in turn a drive (not shown in more detail) for the adjustment of the pendulum roller 1 can act (driving force Fr).
  • a drive not shown in more detail
  • the construction shown in FIGS. 8 to 10 can also work automatically without active position control, as has already been discussed with reference to FIGS. 1 to 3.
  • a normal series roller e.g. a guide roller for paper or corrugated cardboard
  • a normal series roller e.g. a guide roller for paper or corrugated cardboard
  • FIG. 11 corresponds functionally to that according to FIGS. 8 to 10. Only the rigid assembly comprising the rotary bearing axis 35 and holding struts 38, 39 has been supplemented to form a complete frame 44. However, the two ball bearings 36, 37 are arranged analogously to the aforementioned embodiment.
  • FIG. 12 shows a double roller arrangement in which two rollers 45, 46 arranged parallel and spaced next to one another are mounted together on a pendulum frame 47.
  • the latter is articulated analogously to the frame 44 via two ball bearings 36, 37.
  • the pendulum axis Q defined by these in turn runs through the center of gravity W, which lies between the two rollers 45, 46.
  • the pendulum frame arrangement 47 is combined with guide rollers 48, 49 on the inlet and outlet side.
