Definitions

  • the invention relates to a roller according to the preamble of claim 1.
  • Rollers for deflecting, driving or processing strip-like or sheet-like material are used in many different ways in technology, for example as deflecting or driving rolls of belt conveyor systems or of manufacturing, treatment or processing plants for strip-like or sheet-like materials, or as spreader rolls of strip-shaped or web-like material.
  • the object of the invention is to provide a universally usable roller for deflecting, driving or processing tape or web-shaped material, which enables the tapes or webs to be laterally shifted as they circulate around the roller without the edge areas of the tape or the train will be overloaded.
  • the additional tensions occurring during the steering of the band or the web should be distributed as evenly as possible over the cross section of the band or the web in order to avoid local overloads.
  • the invention proposes, starting from a roller according to the preamble of claim 1, the measures listed in the characterizing part of claim 1.
  • the plane of rotation of the casing can be inclined to two sides while maintaining the axis of rotation with respect to the original plane of rotation.
  • the jacket deforms in itself during each revolution in such a way that all of the tape start points are shifted slightly laterally with respect to the tape outlet points over the entire axial length of the jacket.
  • the lateral displacement makes the band-like or web-shaped material which is in frictional engagement with the roller, so that a targeted lateral displacement is possible.
  • the forces causing the lateral displacement can be distributed completely evenly over the width of the belt or web.
  • the features of claim 2 are provided.
  • the rods listed there preferably consisting of spring steel, ensure, with excellent stability of the shell, a uniform distribution of the deformation forces exerted by the inclinable flange rings on the shell and directed parallel to the cylinder axis over the entire shell surface.
  • the circumferential reinforcing inserts proposed in claim 3 provide the jacket with the required arch rigidity without the deformability of the jacket suffering parallel to the cylinder axis.
  • the roller body and the casing can be formed by ring disks made of rubber or plastic which are placed axially on one another on a rotatable axis.
  • the adjusting device for introducing the adjusting forces into the casing can have, for example, simple pressure rollers which act on the flange rings arranged there from one or both end faces of the casing.
  • the roller according to the invention can advantageously also be used for the wide stretching of strip-like or web-like material.
  • the jacket is expediently divided into two separately adjustable sections and an adjusting device with an eccentric pin and an eccentric bushing is assigned to each end. This makes it possible to shift the band or the web in the two adjustable sections to the outside, so that a spreading effect occurs.
  • the strip material can be centered on a spreader roller designed in this way, as has already been explained above. To make a progressive, if necessary, towards the edges To achieve spreading effect, the features of claim 7 are provided.
  • the corrugated or kinked bars impart a greater lateral displacement to the jacket where the kinks or waves are formed higher, namely in the edge regions, than in the central section where the kinks or waves are formed lower and the bars consequently have a higher resistance to deformation to have.
  • the spreading behavior of the roller according to the invention can be optimally adapted to the actual lateral spreading of the strip or web.
  • Fig. 1 the shell of the roller is designated in its entirety with the reference number 1.
  • the roller itself is rotatable about an axis 2.
  • the jacket 1 is deformable by parallel forces (arrow 3) of an adjusting device (not shown in FIG. 1) parallel to the axis 2 such that the plane of rotation E 'of the jacket while maintaining the original axis of rotation against the original plane of rotation E. (shown in dashed lines in Fig. 1) inclined.
  • the run-off points P 2 of a strip running off the roll experience a lateral offset by the amount x compared to the run-on points P 1.
  • This lateral offset x can be set as desired by the respective inclination of the plane of rotation E '.
  • the plane of rotation E ' can of course also be inclined in the opposite direction to the original plane of rotation E, so that the offset x takes place on the other side.
  • the jacket 1 consists of abrasion-resistant, dynamically highly stressable plastic or rubber and is reinforced by reinforcement inserts in the form of axially extending bars 4 and a helical spring 5 extending in the circumferential direction.
  • the rods 4 are distributed at equal distances from one another in the circumferential direction and, like the coil spring 5, are preferably made of spring steel. Correspondingly arranged and designed separate rings can also take the place of the coil spring 5.
  • the rods 4 are mounted on the end face in flange rings 6, between which the rubber or plastic layer of the jacket 1 extends and which are firmly connected to flange bushings 7. These flange bushings 7 are mounted on the axle 2 by means of self-aligning bearings.
  • the axis 2 which is fixed with respect to its spatial arrangement, has at one end an eccentrically arranged pin 9 which projects beyond the self-aligning bearing 8 and on which an eccentric bushing 1o provided with an eccentric bore can be rotated.
  • the eccentric bush 1o is also mounted by means of a second self-aligning bearing 11 on a flange ring 12 which is rigidly connected to the flange ring 6.
  • a spacer sleeve 13 is located between the two self-aligning bearings 6 and 11.
  • the ends of the axis 2 are mounted in fixed bearing blocks 14.
  • the adjusting device shown in FIG. 2 functions as follows: When the eccentric bushing 1o is rotated relative to the pin 9 eccentrically located on the axis 2, the eccentric bushing 1o is displaced perpendicular to the axis 2 and exerts on the flange bushing 7 and the flange ring connected thereto via the self-aligning bearing 11 6 a moment about the pendulum axis of the self-aligning bearing 8, so that the plane of the flange ring 6 is tilted slightly from the position shown. The tilting movement (inclination) is transmitted by means of the rods 4 to the entire casing 1 together with the opposite flange ring 6.
  • the relative rotation of the two parts relative to one another can optionally be controlled by a corresponding measuring device, which detects the deviations from the desired strip travel and gives corresponding correction signals.
  • the bars 4 are interrupted approximately in the middle of the roller and the jacket 1 is additionally supported in this area via roller bearings on the fixed axis 2.
  • eccentric adjusting devices are provided on both axial ends of the roller, as shown in Fig. 2 only at the right axial end of the roller.
  • the bars 4 can optionally be provided with waves or kinks 4a, the height of which increases towards the edges (see FIG. 4).
  • the rods 4 in the edge regions can receive a somewhat smaller resistance to deformation than in the central regions, so that the inclination of the flange ring 6 has a greater effect on the jacket in the edge regions than in the central regions.
  • the bars can also extend over the entire axial length of the roller.
  • the wall thickness of the jacket can increase towards the center, as can be seen from FIG. 3.
  • the jacket 1 and the roller body are formed from a plurality of ring disks 15 made of rubber or plastic, which lie against one another and are attached to a rotatable axis 2 '.
  • the annular disks 15 can optionally be made somewhat thinner in the axial direction below the jacket 1 than in the area of the jacket 1 and in the area directly seated on the rotatable axis 2 '.
  • the jacket 1 is reinforced by axially arranged rods 4 made of spring steel, which are mounted in flange rings 6 arranged on the end face.
  • rings running in the circumferential direction can also be embedded in the annular disks 15 in order to achieve better arch rigidity of the jacket.
  • the adjusting device acts directly on the flange ring 6 by means of a pressure roller symbolized by the arrow 3, and thereby causes the desired deformation of the casing 1 in itself.
