Definitions

  • the 'invention relates to a device for guiding and deflecting flexible extruded material such as profiles, hoses, cables, ropes and the like, the guiding and deflection taking place between two rotatable rollers provided with circumferential circumferential profiles, which are attached to a base at a defined distance from one another Axes of rotation are arranged and form a through-hole largely corresponding to the shape of the strand material between them with the converging circumferential profiles.
  • Guide elements of the double roller principle which have opposing pairs of rollers running on axes and are used to guide hoses, ropes, cables or similar profiles within a defined throughput path and to hold them during the guide process.
  • the disadvantage of these guide elements can be seen in the fact that the profile to be carried out cannot simply be inserted, but rather laboriously threaded and must be pulled out of the space between the rollers after the guide has been completed.
  • Guide elements are also known which have only one sliding roller and which guide the profile to be guided in a deflection around the axis of the roller. These are guide elements that are open on one side, because they have the disadvantage that, at high throughput speeds, changing withdrawal forces and withdrawal directions, the strand material to be guided can jump out of the guide element that is open on one side. These Danger of the strand material jumping out of the roller guide occurs wherever suddenly changing speeds or other stresses on the strand material occur. The disadvantages of these options are obvious, especially wherever loads are transported with the extrudate and its movement, where larger lengths of the extrudate are wound up at high speeds, etc. The consequences of the extrudate jumping out of the guide element are, for example, falling down of transported loads, the uncoiled unwinding of large quantities of the stranded goods due to the high throughput speeds, etc.
  • the invention has set itself the task of avoiding the stated disadvantages and to provide a roller guide that guarantees on the one hand a simple introduction of the strand material into the guide space between the rollers and on the other hand a captive mounting of the rollers on the axes of rotation in the working position, with an additional easy removal of the rollers from the axes of rotation and thus a simple insertion of the strand material, as well as a simple removal in or out of the guide area is possible.
  • the axes of rotation are extended beyond the push-through height of the rollers and each have a thickened head part in this extension, which corresponds to the diameter of the respective central push-through opening of the assigned roller, that the thickenings of the head parts in each case facing each other eccentrically are arranged to the axes of rotation, and that the rollers in the edge regions are designed differently such that the edge of one roller, the edge of the other roller overlaps in an edge zone designed as a special engagement region and that in the engagement position the free edge surface of one engages in the work position Support role against the recessed area of the overlapping edge of the other role.
  • the rollers in the boundary regions are movably supported on the axes of rotation on all sides. Only when the pulling force, which is transferred to the guide rollers via the continuous material, is applied, do the rollers tip against the axes of rotation without losing any of their ability to roll.
  • the direction of tilt of the rollers is directed outwards so that the projections of the thickened head parts facing each other overlap the edge of the through openings of the rollers and thus hold the rollers firmly on the axes of rotation in the force-loaded state.
  • the eccentrically projecting area of the thickened head parts is directed downwards in a beak-like manner and, in the engaged state, engages in an area of the associated rollers which is formed on the through openings of the rollers in a corresponding bevel. In this way, a rolling surface is created in the adhesive state, which works with little wear and provides excellent stability even with high force loads.
  • the base on which the axes of rotation of the rollers are arranged has a thickening serving as a tipping aid for the lower edges of the rollers in the central region between the axes of rotation.
  • the rollers are tilted against the respective axes of rotation immediately after being pushed through, so that the thickened head parts reach over the edge regions of the through openings even in the idle state and in this way make it impossible to lose the rollers from the axis of rotation.
  • this thickening of the base must be held in such a way that the roller can be set up in the region of the axis of rotation by slight pressure from the opposite side and can thus be deliberately pulled off over the thickened head parts.
  • the dimensioning of the height of the thickenings on the base is thus independent of the through openings of the rollers and thus of the tilt angle of the rollers on the axes of rotation in the rest position.
  • a thickening directed towards the overlapped edge regions of the other roller can expediently be arranged on the outer edge regions of at least the overlapping roller.
  • This thickening can of course also be arranged in the upper or lower areas of the overlapped roll. If the thickening in the edge regions of the rollers is the only tilting aid, it is expedient to arrange these thickenings at least in the lower edge region of the overlapped roller so that, like the overlapping roller, it tilts with the edge regions of the passage opening under the eccentric thickenings of the head parts in the idle state and so that it can be held captively on the axes of rotation even in the idle state.
  • (6) indicates the base on which the axes of rotation (1, 2) are held.
  • This support (6) can be a fixed element, but it can also be rotatably mounted so that the possibility of rotation of the support can overlap with the possibilities of rotation of the rollers (3, 4) on the axes of rotation (1, 2).
  • the axes of rotation (1, 2) are fixedly arranged on the base (6), it being possible here to think of a screw connection, a weld or similar fastenings.
  • the axes of rotation (1, 2) have a slim engagement part, the height of which must correspond at least to the push-through height (H) plus the radius of the roller blades. In other words, the height of the axes of rotation (1,2) must be such be specified that the rollers can move freely to a limited extent in all directions on the axes of rotation (1,2).
  • the axes of rotation (1, 2) each have a thickened head part (11, 21), these head parts (11, 21) sitting eccentrically on the axes of rotation.
  • the eccentric projection of the head parts (11, 21) is directed towards one another and, in a preferred embodiment, is formed like a beak projecting downward.
  • the guide rollers (3, 4) are designed in such a way that the guide roller (3) is overlapped by partial areas of the guide roller (4) in an edge zone (5).
  • the edge (32) of the guide roller (3) is overlapped by the edge (42) of the guide roller (4), the free edge surface (321) against the recessed area (421) of the overlapping edge (42) in the force-loaded state Supporting the guide roller (4).
  • the upper and lower free edge areas of the guide roller (4) are each provided with a circumferential thickening (421, 441).
  • the thickening (421) in the upper edge area serves as support on the edge (32) of the overlapped roller (3).
  • the thickening (441) serves as a tipping aid, whereby the tipping aid can be reinforced by the additional thickening (61) of the base (6).
  • the overlapped guide roller (3) also has such a thickening (341) in the lower edge region (34), which serves in a corresponding manner as an additional tilting aid.
  • the thickenings (341, 441) are to be solely responsible for tilting the rollers (3, 4) on the guide axes (1, 2) without the additional tipping aid (61), it is advisable to design the base (6) in such a way that that the outward-facing edge regions of the guide rollers (3, 4) project freely over the base (6), so that the circumferential thickened portions (341, 441) protrude beyond the edge of the base and thus there is a possibility.
  • FIG. 2 In contrast to FIG. 1), with its differently designed guide rollers (3, 4), an embodiment is shown in FIG. 2 in which only a single roller shape is required for the guide rollers (3, 4).
  • the guide rollers (3, 4) are simply placed on the axes of rotation (1, 2) in reverse order.
  • the edge (42) of the roller (4) overlaps the edge (32) of the roller (3) in the upper region, while the recessed edge (45) of the guide roller in the lower region is a mirror image (4) is overlapped by the overlapping edge (35) of the guide roller (3).
  • a position of the guide rollers (3, 4) between the position shown in FIG. 1) and the position shown in FIG. 2) can be achieved, in each case according to the given direction of force.
