Definitions

  • the invention relates to a device for aligning belts, in particular metal belts, with at least two conveyor tracks arranged in different planes, via which the belts can alternately be fed to a processing station, a guide roller being provided in the conveying direction in front of the processing station, which guide roller is on one of the conveyor tracks conveyed belt to the processing station.
  • Devices of this type are used, for example, to center a steel belt fed from a reel on a conveyor track into a continuously operating production line with respect to the width of the conveyor track before it is connected to the end of the belt previously processed in the production line. For this alignment it is usually necessary to apply transverse forces to the belt.
  • Aligning a belt lying flat on a conveyor track is particularly difficult when the belt has a high degree of rigidity in the transverse direction due to its dimensions and material properties. With such belts, particularly high lateral forces have to be applied for the central alignment. In particular when centering wide steel strips, this entails the risk of that the tapes buckle when damaged by the alignment forces.
  • a disadvantage of this procedure when aligning a band is, however, that a great deal of space is required in order to provide a loop length which is sufficient for centering the band.
  • This required loop length is particularly large if the band is a steel band of great thickness and the inherent rigidity associated with it in the plane of the band.
  • the alignment of belts of great inherent rigidity is particularly problematic when, as in the prior art known from practice mentioned above, there are at least two conveying paths arranged in different planes, by means of which the belts are alternately conveyed.
  • the guide roller is required in order to deflect at least that belt which is being conveyed on a level deviating from the level of the feed path in such a way that it moves on the feed path to the processing station in the orientation required for further processing, which is independent of the
  • the course of the conveyor tracks must always be the same before the belt enters the station.
  • the space requirement for the formation of the feed section proves to be particularly high because, in the prior art, the length of the strip is added to the length of the loop, which is required to deflect the strip from an offset plane. The required lengths increase approximately in proportion to the thickness of the tape.
  • the object of the invention is to reduce the space requirement of a device of the type mentioned at the beginning with simple means.
  • a device for producing a loop is arranged in the region of the conveyor tracks, and that a deflection device is arranged adjacent to the guide roller, which device consists of a rest position in which it Band not touched, is movable into a working position in which it lifts the belt from the guide roller, and that the deflecting device is designed in the region of its contact surfaces contacting the belt such that in the event of contact with the belt, an essentially transverse alignment movement of the conveyor Band is enabled.
  • the area in which the loop is formed is shifted to the area in which the deflection of the tape brought in at different levels takes place.
  • this also applies if one of the conveyor tracks is aligned with the feed path of the processing station.
  • the overall length of a device designed according to the invention can be considerably reduced compared to the prior art.
  • the overall length can be reduced by up to half, since in such cases the same length is required in each case for the deflection and the loop formation in the prior art.
  • a device in the region of the guideways in the conveying direction in front of the guiding roller with which a loop can be formed in the belt conveyed on the respective conveying path.
  • a deflection device by means of which the band is held at a distance from the guide roller during the centering process.
  • the deflection device enables a transverse movement of the belt.
  • a practical, easy-to-manufacture device is characterized in that the position of the guide roller is fixed and the deflection device can be moved from a rest position, in which the tape lies against the guide roller, to a working position in which it lifts the tape off the guide roller.
  • the deflection device can be moved from a rest position, in which the tape lies against the guide roller, to a working position in which it lifts the tape off the guide roller.
  • the space or the special features of the belt to be aligned do not allow the deflection device to be adjusted, then it is favorable to fix the position of the deflection device and to move the guide roller from a working position in which it touches the belt into a rest position in which it is lifted off the belt.
  • An advantageous embodiment of the invention is characterized in that the deflection device has a plurality of rollers, the axes of rotation of which are aligned parallel to the conveying direction of the belt and the peripheral surfaces of which in the working position are the contact surface of the deflection device form.
  • rollers enable an almost friction-free transverse displacement of the belt, so that a deflection device designed in this way can also be used with belts whose surface needs to be protected.
  • a further practical embodiment of the invention is characterized in that a guide roller is assigned to the top and the bottom of the belt, that the guide roller which is arranged on the side of the belt opposite the deflection device, from a working position in which it is the belt touches, in a rest position in which it is lifted off the belt, is adjustable and that the movement of the adjustable guide roller is coupled to the movement of the deflection device such that the adjustable guide roller is in its rest position when there is contact between the deflection device and the belt located.
  • the arrangement known from practice one guide roller each on the top and bottom of the belt enables particularly precise guidance of the belt. By lifting the guide roller arranged on the side opposite the deflection device from the belt when the belt is centered, it is ensured that this roller is not damaged when centering the belt. In addition, this lifting frees up a space into which, if necessary, the band can be pressed by the deflection device at a distance from the respective other guide roller.
  • Automation of the alignment process can be carried out particularly easily if a control device is provided which controls the relative position of the deflection device and guide roller during an alignment process.
  • a control device which controls the relative position of the deflection device and guide roller during an alignment process.

  • the device for aligning a steel strip B is part of a production line in which the steel strip B is processed. Upstream of the device in the conveying direction F are, for example, two uncoiling devices, not shown, from which the steel strip B is fed into the device.
  • Each of the uncoiling devices is assigned a conveyor track 1, 2 of which the first conveyor track 1 is arranged horizontally.

  • Alignment devices 7 and 8 are arranged laterally on each conveyor track 1, 2 in the area of their respective rear ends 1 a and 2 a. These exert lateral forces on the steel belt B via pressure elements (not shown) for the central alignment of the steel belt B in relation to the width of the conveyor tracks 1, 2.
