Definitions

  • the invention relates to an alignment device of tapes, especially metal tapes, with at least two arranged in different levels Conveyor tracks over which the belts alternately one Processing station can be fed, wherein in Direction of conveyance in front of the processing station Guide role is provided, which on one of the Conveyor lanes conveyed belt to the processing station passes.
  • Such devices are, for example used to get one from a reel on a conveyor in a continuously working production line steel strip fed in with respect to the width of the Center conveyor before it reaches the end of the previous one band processed in the production line becomes. It is usually for this alignment required to apply transverse forces to the belt.
  • Aligning a flat on a conveyor track tape is particularly difficult when the tape due to its dimensions and Material quality in the transverse direction is high Has rigidity. With such tapes for the centric alignment of particularly high lateral forces be applied. This brings in particular with Centering wide steel strips with the danger that the tapes are loaded with the aligning forces buckle and be damaged.
  • Aligning belts is particularly problematic great rigidity when, as in the beginning mentioned prior art known from practice, at least two arranged in different levels Conveyor routes exist over which the belts are promoted alternately.
  • the guide roller is needed to fixtures at least the band on one of the levels the feed path deviating level is promoted, so to redirect that it is on the feed path to the Processing station in the for further processing required orientation that moves regardless of Course of the conveyor tracks before the belt enters the station must always be the same.
  • the object of the invention is simple Means the space requirement of a device of the beginning to reduce the type mentioned.
  • the area in which the loop is formed, in the area is shifted in which the redirection of the at different levels takes place.
  • this also applies if one of the conveyor tracks aligned with the feed section of the Processing station is arranged. That way the overall length of a trained according to the invention Device considerably compared to the prior art be reduced. This can be done in many Use cases, for example when aligning thicker Steel strips that reduce the overall length by up to half, because in such cases in the prior art for Redirection and the formation of loops each a distance of the same length is required.
  • the device according to the invention is characterized in that that the position of the guide roller is fixed and the Deflection device from a rest position in which the belt in contact with the guide roller in a working position is movable in which the tape from the guide roller takes off.
  • Such a configuration is particularly then useful if the effort for adjusting the Leading role based on their weight and dimensions would be great.
  • Adjustment of the deflection device is not too, so it is favorable to fix the position of the deflection device and the leadership role from a working position in which she touches the tape, in a resting position in which she is lifted off the belt.
  • deflection means a plurality of rollers, whose axes of rotation parallel to Direction of conveyance of the belt are aligned and their Circumferential surfaces in the working position, the contact surface form the deflection device.
  • Another practical embodiment of the invention is characterized in that the top and the Underside of the tape each has a guide role is assigned that leadership role that on the opposite side of the deflection Band is arranged from a working position in which she touches the tape, in a resting position in which she is lifted off the belt, is adjustable and that the Movement of the adjustable guide roller with the movement the deflection device is coupled such that the adjustable guide roller in case of contact between the Deflection device and the belt in its rest position located.
  • the arrangement known from practice one leadership role each on the top and the Bottom of the band allows a particularly accurate Leading the tape.
  • the device for aligning a steel strip B is Part of a production line in which the steel strip B is processed.
  • the device in the conveying direction F upstream are, for example, two not shown Decoilers, of which the steel strip B in the Device is fed.
  • Each of the uncoilers is not shown each assigned a conveyor track 1,2, of which the first conveyor track 1 is arranged horizontally.
  • the second Conveyor track 2 is above the first conveyor track 1 arranged and inclined to the first, with its rear end in the conveying direction F of the belt B. 2a lies lower than its front end in the conveying direction F. 2 B.
  • a lifting device 3, 4 is located on each conveyor track 1, 2 attached. This consists of roles 5, which are rotatably supported at one end of pivot levers 6. With their other end, the swivel levers 6 are on the respective conveyor track 1.2 pivotally attached.
  • each conveyor track 1,2 are in the range of their respective rear end 1a or 2a laterally Alignment devices 7 and 8 arranged. Practice this via not shown pressure elements for centric Align the steel strip B based on the width of the Conveyor tracks 1.2 lateral forces on the steel belt B out.
  • Both conveyor tracks 1, 2 end in the conveying direction F at one Table 10.
  • the table 10 is attached to a holder 11, which is pivotable about a pivot bearing 12 on one Frame 12 is held.
  • a first guide roller 13 rotatably mounted is arranged below the steel strip B and transversely extends to the conveying direction F over its width.
  • a second guide roller 14 arranged, which is also across the width of the Steel strip B extends.
  • the upper guide roller 14 is rotatably mounted on a holder 15 which is fixed with one in the conveying direction F with a distance behind the Guide rollers 13, 14 arranged frame wall 16 of the Frame 12 is connected.
  • the steel strip B is through the Guide rollers 13, 14 horizontally through one in the Frame wall 16 formed deflection gap 17 in Direction of conveyance F downstream, not shown Processing station fed.
  • one Deflection device 20 arranged in the by the spaced arrangement of the frame wall 16 and the guide roller 14 formed space. This shows one transversely to the direction of conveyance F of the steel strip B via its Width extending and above the steel strip B arranged roller cage 21.
  • the roller cage 21 In the roller cage 21 are stored a plurality of rollers 22, the Axis of rotation 22a parallel to the conveying direction F such is arranged that the rollers 22 on the steel belt B put on and across the conveying direction F on the steel belt B can roll.
  • the roller cage 21 is vertical aligned lifting rods 23, which are part of hydraulically, mechanically or pneumatically operated Actuators 24 are.
  • the actuating devices 24 are fixed to the frame wall 16 attached and with a not shown Control device connected. This control device monitors and controls the relative location of the Deflection device 20 and the guide roller 14 and the Swivel position of the holder 11 with the attached to it Table 10 and guide roller 13.
  • the steel strip B is applied of forces Q directed transversely to the conveying direction F. with respect to the width x of the deflection gap 16 or Centered conveyor tracks 1,2.
  • the rollers 22 roll on the steel belt B and thus enable one unhindered transverse movement of the steel strip B.
  • the roller basket 21 the deflection device 20 with the rollers 22 raised until the deflection device 20 again in its Rest position.
  • the lower one Guide roller 13 and the table 10 back in their Working position swiveled.
