Definitions

  • the invention relates to a method for operating a rolled strip reel, the drum of which consists of a plurality of expandable segments which, with wedge-shaped support surfaces, are axially displaceably supported against a hollow shaft rotatably mounted in a reel housing and are adjusted by means of a stamp arranged in the hollow shaft and adjustable by means of an actuator , the reel housing for receiving the band bundle on the drum by means of a sliding drive, first in the direction of the band bundle and then when spreading the segments to eliminate the relative axial displacement between the segments and the hollow shaft in the required direction on its guide bed parallel to the drum axis is moved.
  • the invention is concerned with a rolled strip reel, the drum of which consists of a plurality of expandable segments which, with wedge-shaped support surfaces, are axially displaceably supported against a hollow shaft which is rotatably mounted in a reel housing and which is arranged in the hollow shaft and by means of an actuating drive for spreading the drum segments with simultaneous axial displacement of the same adjustable stamp, and which with a pushing in and out of the reel drum relative to.
  • Band bundle and / or the slider drive effecting the center of the strip control is equipped for the reel housing.
  • roll coiler is already known, the drum of which consists of several expandable segments which are supported axially displaceably with wedge-shaped bearing surfaces directly against a central hollow shaft rotatably mounted in a reel housing, and can be adjusted relative to the latter by means of a plunger arranged in the hollow shaft.
  • Wall reels of this type are advantageous in that the direct support of the drum segments on the circumference of the hollow shaft enables relatively small dimensions to be achieved, which result in a considerable reduction in the moment of inertia. This naturally also reduces the acceleration, braking and quick stop moments that occur during operation.
  • the bearing diameter for the reel shaft can be reduced considerably, so that the bearing wear is reduced even when the operating speeds are increased.
  • a non-generic roll coiler the drum of which consists of several expandable segments, which are supported axially displaceably with wedge-shaped bearing surfaces against a full shaft rotatably mounted in a reel housing and are adjusted by means of an adjusting device, has become known from US Pat. No. 3,456,893.
  • This roll coiler is spread by means of a sleeve which is axially displaceable on the full shaft and is connected to the segments.
  • the expansion drive for moving the sleeve serves at the same time as a displacement drive for the reel housing, the axial displacement causing the expansion of the drum segments to be derived from the primary movement of the displacement movement of the reel housing.
  • considerable mechanical effort is required for the double function of the actuator.
  • the invention has for its object to achieve with little additional technical effort that the unwinding of the rolled strip from the coil can take place immediately after the tensioning process, and that the displacement movement for the reel housing on the reel bed is made indirectly dependent on the spreading movement of the drum segments.
  • this object is achieved in a simple manner by tapping the extent of the relative glazing between the segments and the hollow shaft and converting it into negative feedback into the opposite displacement movement of the reel housing on the reel bed of the appropriate size.
  • the drum segments always maintain their predetermined relative position to the center line of the infeed of the processing systems downstream of the reel during their movement for tightening the coil, thus ensuring that the rolled reel can be put into operation immediately after the tensioning process has ended.
  • the relative displacement of the plunger to the hollow shaft is measured and used as a manipulated variable for the oppositely directed displacement drive of the reel housing. Since the relative displacement of the plunger relative to the hollow shaft corresponds to the relative displacement between the segments of the reel drum and the hollow shaft carrying and guiding it, the respective correction quantity can be determined in this way easily and with the least possible relative error.
  • a roll coiler for carrying out this method the drum of which consists of several expandable segments which are supported axially displaceably with wedge-shaped bearing surfaces against a hollow shaft rotatably mounted in a reel housing, the drum being arranged in the hollow shaft and by means of an actuator for spreading the drum segments at the same time
  • Axial displacement of the same adjustable plunger and equipped with a displacement drive for the reel housing, which causes the reel drum to be pushed in and out relative to the band bundle and / or the band center control is essentially distinguished according to the invention in that a measuring device for measurement is located between the segments and the hollow shaft the relative axial displacement between the segments and the hollow shaft is arranged, which is connected to a control element for the opposite actuation of the displacement drive.
  • the measuring device is in actuating connection with the rear end of the stamp displacing the segments and that the control element assigned to the disk drive is path-dependent on the one hand by the measuring device and on the other hand by a distance measuring device between the reel housing and the reel bed is adjustable and adjustable.
  • both the expansion drive for the drum segments and the displacement drive for the reel housing each consist of a double-acting hydraulic cylinder, and that the hydraulic fluid supply to the displacement drive can be influenced by a control valve controllable by the measuring device.
  • a rolled strip reel is shown, the hollow shaft 1 of which is axially displaceable but rotatably driven in roller bearings 2 of the reel housing 3.
  • the reel housing is guided displaceably on a stationary reel bed 4 in the direction of the longitudinal axis of the hollow shaft 1 and can be moved thereon by a displacement drive 5, for example a hydraulic cylinder.
  • the hollow shaft 1 is provided with wedge-shaped support surfaces 7, on which several, for example four, segments 8 are held and guided via support surfaces 9 which are also wedge-shaped.
  • the segments 8 together form the actual reel drum 10, which can be expanded or contracted, if necessary, in that the segments 8 held with their wedge-shaped support surfaces 19 on the wedge-shaped bearing surfaces 7 of the hollow shaft 1 simultaneously axially relative to the hollow shaft 1 be moved.
  • the axial displacement of the segments 8 relative to the hollow shaft 1 is forced by a plunger 12, which is guided centrally in the hollow shaft 1, engages the segments 8 in front of the front end of the hollow shaft 1 via a driver flange 13 and by one at the rear end of the hollow shaft 1 arranged hydraulic cylinder 14 can be moved axially.
  • the reel drum 10 is contracted radially or contracted when the plunger 12 has been pushed to the left by the hydraulic cylinder 14. To spread the drum 10, however, it is necessary to pull the punch 12 through the hydraulic cylinder 14 to the right, as can be seen from the upper half of FIG. 4.
  • the entire rolled strip reel with the radially contracted reel drum 10 must first be pushed onto the stationary reel bed 5 from the position according to FIG. 1 into the position according to FIG. 2.
  • This movement is brought about by the displacement drive 5 and, for example, limited by a limit switch 18, in that this interrupts the supply of the hydraulic fluid to the hydraulic cylinder 5.
  • the limit switch 18 determines the basic position of the rolled strip reel which ensures the proper strip run into the further processing system.
  • This basic position of the rolled strip coiler can then be corrected automatically during the unwinding operation by a so-called strip center control, by influencing the displacement drive 5 accordingly.
  • the reel drum 10 must first be spread within the central opening 19 of the coil 17. However, since this spreading movement is accompanied by an axial displacement of the drum segments 8 relative to the hollow shaft 1 or to the reel housing 3, care must be taken to ensure that the resulting axial displacement of the band collar 17 from its running center plane 20-20 is practically completely eliminated.
  • a measuring device 21 is arranged between the hollow shaft 1 and the plunger 12 which can be displaced, which precisely determines the relative displacement between these two parts and converts it into a manipulated variable which influences the displacement drive 5 for the reel housing 3, specifically in the Way that the reel housing 3 is moved completely automatically and in each case by the appropriate amount on the stationary reel bed 4 in the opposite direction to the axial adjustment of the drum segments 8.
  • a control value sensor 23 can be used as the control element for the control valve 22 which effects the hydraulic supply to the displacement drive, in that on the one hand the measured variable determined by the measuring device 21 is continuously entered and which on the other hand is influenced by a distance measuring device 24 arranged between the reel bed 4 and the reel housing 3.
  • the measuring device 21 and the distance measuring device 24 work together with the actuating value transmitter 23 in such a way that the latter keeps the control valve 22 open as long as there is a difference between the measured values determined by the measuring device 21 and the measured values by the distance measuring device 24. Only when the difference between the two measured values determined by the measuring device 21 and the distance measuring device 24 in the manipulated-value transmitter 23 has become zero, does the manipulated-value transmitter 23 close the locking valve 22 and thus put the sliding drive 5 out of operation.
  • the displacement drive 5 is inevitably controlled in the direction of the arrow 26 so that it moves in the opposite direction to the displacement direction 25 of the reel drum 10 and thereby always holds the band collar 17 exactly on the drainage medium level 20-20.
  • the displacement drive 5 in this case can stop it Limit switches 18 can be used simultaneously to make the distance measuring device 24 effective.
  • both the measuring device 21 and the distance measuring device 24 work capacitively or inductively and to design the associated actuating value transmitter 23 as a measuring pressure which, depending on its respective state, either opens or closes the control valve 22.
  • the above-described measures can be used to create a rolled strip reel, the reel drum 10 of which is completely automatically and precisely aligned with the predetermined center flow level 20-20, although its segments 8 are used for the purpose of spreading or contracting relative to that they carrying hollow shaft 1 must be subjected to an axial displacement.
