Definitions

  • the invention relates to a roller belt apparatus for displaying information or the like. with two mutually substantially parallel spaced winding rollers and a roller conveyor, in particular made of a plastic film, which can optionally be wound from one winding roller and onto the other winding roller, and with a device for preventing the migration of the roller conveyor from its normal position .
  • Roll tape devices of this type have been used many times in the past to make advertisements and information of different types visible. As soon as these conveyor belts exceed a certain size, it has a negative effect when the conveyor belts move out of their normal position to the side. Such emigration leads to a particular stress on the belt edges of the roller belt and ultimately to its destruction. This load on the belt edges is therefore unfavorable, since you often want to use the roll tape only as a carrier tape, on which the individual information carriers are exchangeably attached. It is therefore important that the roller belt itself is as long-lasting as possible.
  • At least one of the winding rollers is mounted displaceably in the axial direction, and that the device comprises an actuator for moving the winding rollers, at least one non-contact sensor for detecting emigration movements of the conveyor belt and a control system which depends on the Sensor delivered signal actuated the actuator of the winding roller.
  • This solution has the advantage that the winding roller is displaced more or less laterally to the direction of movement of the roller belt depending on the type of migration efforts of the roller belt. In this way, the emigration of the conveyor belt can be gently corrected without the belt edges being excessively stressed. Furthermore, no mechanical guidance of the band edges is required; the sensor is only intended to detect deviations of the tape from its normal position in order to avoid this to the regulation.
  • both winding rollers can also be slidably mounted, which simplifies the control.
  • the senor is an optical sensor, preferably a light barrier.
  • the sensor is provided on a frame in the area of the belt edge of the roller belt.
  • light barriers can be provided on both belt edges of the roller belt.
  • both winding rollers are provided with an actuator.
  • FIG. 1 is a schematic representation of the rear view of a roller belt apparatus according to the invention with the housing open,
  • Fig. 2 is a detailed view of a displacement unit.
  • a roller conveyor is shown schematically in a cut open housing on the back.
  • the roller belt apparatus comprises an upper winding roller 1 and one to this, parallel and spaced lower winding roller 2. Both winding rollers 1 and 2 are each connected via a gear pair 4 or 4 'to a drive motor 3 or 3'. On the two winding rollers 1 and 2, a roller belt 5 is wound, of which only the back can be seen in FIG. 1. The roller belt can be wound up from the upper winding roller 1 to the lower winding roller 2 and vice versa.
  • both winding rollers 1 and 2 are mounted so as to be displaceable in the direction of their axes 6 and 6 'and thus transversely to the winding direction of the roller belt 5.
  • the gear pairs 4 and 4 ' take this displacement possibility into account in that the pinion is designed to be correspondingly long.
  • the winding roller is mounted on the end facing away from the drive motor on a shaft stub ⁇ fixed to the housing in the direction of the double arrow S so that it can be moved and rotated.
  • an adjusting sleeve 9 is arranged on the axle shaft 8 and is rotatably mounted on the axle shaft and on which an adjusting arm 11 can be rotated, but is not slidably mounted, via a ball bearing 10.
  • the adjusting arm 11 At its end facing away from the winding roller 2, the adjusting arm 11 has a through hole 12 with an internal thread, which extends parallel to the stub shaft 8.
  • A extends through the through hole 12 in the housing rotatably mounted threaded spindle 13, which is mounted on the shaft of a servomotor 14, which in turn is attached to the housing.
  • a similar displacement device 7 ' is provided on the upper winding roller 1, as can be seen from FIG. 1.
  • the adjusting motors 14 and 14 'of both displacement devices 7 are connected to a control unit 15. Furthermore, 5 optical sensors 17 are attached in the area of the tape edges 16 of the roll tape 5, which register a lateral offset of the tape edges 16 and thus of the roll tape 5. Both sensors 17 are also connected to the control unit 15. Finally, the drive motors 3 and 3 'of the two winding rollers 1 and 2 are also connected to the control unit 15. A control panel, which is also connected to the control unit 15, is not shown for the sake of clarity.
  • roller conveyor apparatus The operation and functioning of the roller conveyor apparatus according to the invention will now be explained in more detail below.
  • the control unit can now be given the command that the roller conveyor should move upward and thus be rolled up by the upper winding roller 1 via the control panel (not shown in more detail).
  • the roller belt 5 can migrate sideways. Such lateral migration of the roller belt is registered by the sensors 17, whereupon, according to a predetermined program, either the adjusting motor 14 for the lower winding roller 2 or the adjusting motor 14 'for the upper winding roller 1 is actuated to prevent the migration of the Counteracting the conveyor belt.
  • One possibility of regulation consists, for example, in that when the roller belt 5 is wound onto the upper winding roller, the lower winding roller 2 is laterally displaced in such a way that the belt edges 16 of the roller belt 5 are always guided in a certain desired range, the observance of which by the sensors 17 monitored and guaranteed by appropriate signaling of the control unit 15. Another possibility would be to move the upper winding roller 1 in the same direction in which the roller belt 5 migrates when winding it up. Because of these different control options, it is also conceivable that only one of the winding rollers is arranged displaceably, while the other winding roller is rigid. If, however, as in the embodiment shown here, you have two slidable winding rollers available, the control program ⁇ ⁇ _mm can also be designed as one.

Abstract

Dans un appareil à bande roulante pour l'affichage d'informations etc., lequel comporte deux cylindres d'enroulement opposés (1, 2) sensiblement parallèles et distants, ainsi qu'une bande roulante (5), il s'agit d'empêcher de manière simple que la bande roulante (5) ne dévie de sa position normale lors de l'enroulement ou du déroulement. A cet effet, au moins l'un des cylindres d'enroulement (1, 2) est mobile le long de son axe. Le cylindre d'enroulement mobile est déplacé par l'intermédiaire d'un servomoteur en fonction de capteurs sans contact (17) détectant la déviation, afin de s'opposer ainsi à cette déviation.
