Definitions

  • the invention relates to a method for guiding a belt transversely to its running direction according to the preamble of claim 1.
  • the invention relates to a device for guiding a tape transversely to its running direction according to the preamble of claim 4.
  • Running webs in particular when processing paper and plastic webs, can migrate in an undesirable manner transverse to their running direction. This also applies to endless belts, especially conveyor belts.
  • belts For the sake of simplicity, webs, endless belts, strips of material, belts and the like are summarized below under the term belt.
  • passive and active tape guiding devices are known from the prior art.
  • Passive guiding devices are understood to mean devices which ensure a stable position of the belt without an external force acting on the device for the purpose of controlling the belt.
  • passive tape guiding devices cannot meet the high requirements for a particularly precise maintenance of the edge position of the tapes and for a response of the guiding device that is as delay-free as possible, which is why active tape guiding devices are often preferred.
  • Active tape guide devices are distinguished from the passive tape guide devices by a faster correction of the edge position in the event of any deviations.
  • An active tape guide device is known for example from DE-OS 39 34 241.
  • the arrangement described there for guiding a running belt has a roller which is rotatably mounted at one end relative to the frame of the machine and at the other end rotatably on a control apparatus.
  • the control apparatus has a swivel arm connected to the roller and an auxiliary arm which are coaxially rotatably coupled.
  • a liquid bellows is provided between the auxiliary arm and the frame or the frame piece, the position of the auxiliary arm with respect to the frame being regulated by regulating the amount of liquid in this bellows.
  • the roller is rotated about the axis and thus the direction of the axis of the roller in relation to the longitudinal direction of the belt, and the roller is influenced accordingly for displacing the belt in its transverse direction.
  • a disadvantage of the known device is that a first of the two axle suspensions is stationary. The control movement is carried out by the second axle suspension coupled to the control apparatus alone. As a result, the tension in the running band changes much more on the side of the second suspension than on the side of the first. The constantly acting voltage difference can lead to distortion in the finished product.
  • the one-sided fixed suspension also has a disturbing effect because an extension of the tape path, and thus an expansion of the tape is required for a correction of the tape position in the direction of the first suspension, while the tape path must be shortened for a correction movement in the direction of the second suspension and consequently the tension subsides.
  • the former case particularly in the case of tapes made from materials which are not very elastic, can lead to tape damage which, owing to the asymmetry of the device, only occurs on one side of the tape.
  • Another tape guide device is known from DE-GM 91 08 408.
  • a device for guiding a belt transverse to its running direction which comprises a frame and a control roller partially wrapped around the belt.
  • the control roller is rotatably mounted about an axis, and the axis of rotation of the control roller has a desired position in which the belt can be guided uniformly with a constant belt edge distance with respect to the frame.
  • the axis of rotation in turn, can be rotated between the set position and tape return positions, in which a lateral displacement of the tape can be corrected. If the belt runs in its desired position, it is loaded evenly along its width by tensile stress. This tension is necessary if the belt is moved over one or more rollers.
  • control roller axis increases the tension on the side of the belt that moves away from the target position of the belt center. At the same time, the tension on the other side of the belt drops. Due to the difference in tension in the belt, restoring forces are exerted on the belt, which act essentially transversely to the direction of travel and move the belt back into the desired position.
  • the control roller is arranged on both sides of a cylinder piston unit, whereby one piston side is acted upon by a pneumatic and one piston side via a hydraulic line system that communicates with both cylinders.
  • This device is distinguished from the device described first in that the center of the control roller is at rest during the regulating movement, so that the total tension of the belt remains constant.
  • the extent of this belt path change is smaller with the same control effect on the belt than in the case of the device from DE OS 39 34 241.
  • the elongation of the band is proportional to the stroke of the control movement and, in the case of large strokes, can lead to unacceptable stress on the band, which damage the band on both sides.
  • a device for guiding a belt transversely to its running direction which comprises a control roller which can be pivoted on a frame and which is partially wrapped around by the belt.
  • the control roller When the belt is at the desired position, the control roller is in its desired axis position.
  • the nominal axis runs parallel to the axes of upstream and downstream pulleys over which the belt is guided.
  • the control roller When the belt is displaced laterally, the control roller is pivoted in such a way that the center of the control roller remains at rest and the intersections of the control roller axis move in the same direction on circular paths with two planes running perpendicular to the desired axis.
  • control roller must be suspended on both sides.
  • the proper functioning of these tape guiding devices is endangered by the dusts which arise in particular when processing paper and plastic webs and which can be deposited on the suspensions. Such contaminants can also get onto the belt, which in many cases leads to waste (waste).
  • the object of the invention is to provide a method and a device with which belts are guided exactly transverse to their running direction, the risk of the belt being overstretched by large control movements is eliminated.
  • the invention provides the features of claim 1.
  • restoring forces are exerted on a running belt when the belt moves in an undesired manner transversely to its running direction, which forces the belt back into its desired position.
  • the belt is guided transversely to its running direction with the aid of a control roller partially wrapped around the belt.
  • the control roller axis is in its target axis position when the belt is at the desired position.
  • the setpoint axis runs parallel to a stationary holding axis on which the control roller is pivotably arranged.
  • the control roller axis is pivoted such that its intersections with two planes running on the desired axis move in opposite directions on circular paths, the center points of the circular paths lying on the holding axis.
  • the pivoting has the desired consequence that, with small displacements of the band, the band travel on one side of the band is slightly lengthened and slightly shortened on the other side of the band, and that, with large displacements, the band paths on both sides of the band are caused by large pivoting movements shorten, but this in different ways. This reliably prevents inadmissible overstretching of the belt.
  • the pivoting movement of the control roller axis is superimposed on an axial movement of the control roller parallel to the target axis.
  • the path and direction of the axial movement are advantageously in a fixed relationship to the pivoting movement of the control roller.
  • the invention further relates to a device for guiding a belt transversely to its running direction with a control roller partially wrapped around the belt, which is pivotably arranged on a stationary frame, the control roller axis being in its desired axis position when the belt is in the desired position.
  • Two eccentrics are rotatably arranged on a holding axis for the control roller carried by the frame, which are connected via a coupling device and can be driven in opposite directions.
  • the control roller is rotatably supported on the eccentric via bearings. When the belt is in the desired position, the eccentrics are aligned with one another in such a way that the control roller axis runs parallel to the holding axis.
  • the bearings are roller bearings on the eccentrics. This enables a low-friction rotary movement of the control roller, which promotes a long service life of the device.
  • the device according to the invention can be implemented in various ways, as will be shown below using two exemplary embodiments.
  • the coupling device consists of a pinion with a fixed axis of rotation, which is attached to the holding axis and is perpendicular to the holding axis, the pinion being arranged between two sleeves toothed on the edge, each of which is rigidly connected to an eccentric.
  • a rotating rod is arranged in the interior of the holding axis, which is rigidly connected at one end to a rotary drive and is rigidly connected to one of the eccentrics at the opposite end.
  • the second embodiment of the invention is characterized in that the coupling device consists of two sleeves, each with an elongated hole running helically on an outer surface of each sleeve, into which a pin rigidly connected to the holding axis engages.
  • the smoothness of the screw line on both sleeves is opposite.
  • a sleeve is rigidly connected to an eccentric and forms an eccentric unit with it.
  • a connecting device is arranged between the eccentrics, which keeps their distance constant, but enables their rotation relative to one another.
  • the connecting device between the eccentrics preferably consists of the roller bearings and the control roller.
  • This device makes it possible in a simple manner to couple an axial movement of the control roller with the pivoting movement. With the help of the axial movement of the control roller, in which the belt is carried laterally, it is possible to react very quickly to a displacement of the belt from the desired position.
  • the free rotation of the eccentrics relative to one another at a constant distance can be ensured in a particularly simple manner by including the roller bearings and the control roller in the connecting device.

Abstract

L'invention concerne un procédé de guidage d'une bande transversalement à sa direction de déplacement au moyen d'un rouleau de commande (12) qui est partiellement entouré par la bande et qui, lorsque la bande (14) est dans sa position de consigne, se situe dans sa position axiale de consigne. Lorsque la bande (14) se déplace latéralement hors de sa position de consigne, l'axe (SA) du rouleau de commande pivote de sorte que ses points d'intersection avec des plans (E1, E2) perpendiculaires à l'axe de consigne (0, 0) se déplacent en sens contraires sur des trajectoires circulaires (+, 0, -). L'axe de consigne (0, 0) est parallèle à un axe fixe de retenue (32) du rouleau de commande (12) et le centre des trajectoires circulaires (+, 0, -) se situe sur l'axe de retenue (32). Même lors de fortes déviations de la bande, le fort pivotement du rouleau de commande (12) ne cause pas de tensions inadmissibles dans la bande (14) qui pourraient l'allonger excessivement. L'invention concerne en outre un dispositif qui permet de faire pivoter de manière simple le rouleau de commande (12). Le dispositif est compact, étant donné que tous les composants nécessaires pour faire pivoter le rouleau de commande (12) peuvent se situer à l'intérieur de celui-ci.
