Definitions

  • the invention is based on a reversible reel with two reels, which are mounted on a rotatable head plate and can be driven independently of one another and are intended for the successive continuous winding of rolled strip, each of which has drums which consist of a plurality of segments which can be spread and which are axially displaceable with wedge-shaped sliding surfaces support the reel shafts mounted on the head plate, designed as hollow shafts, which are penetrated by punches which can be axially displaced by means of actuators, the free ends of which are connected to the segments by means of connecting flanges for transmitting the spreading or de-spreading movement, and in which the reel is rotated by rotating the head plate are cyclically movable from a starting position to a transfer position.
  • the known reversible reel corresponding to the genus has actuators which are firmly connected to the reels and which considerably increase the masses of the system to be accelerated or braked, so that large and expensive drives, gears and couplings are necessary.
  • the drive medium required for the operation of these actuators e.g. a hydraulic oil
  • a pressure accumulator is assigned to each reel in addition to the actuator that is firmly connected to it, which has to carry out the corresponding rotary movements, so that this also incurs considerable system and operating costs.
  • the object of the invention is to create a reversible reel which is simple in construction and can be produced cost-effectively and which does not require media feeds to the actuators which are susceptible to faults.
  • the plunger of the reel keeps the segments of the drums in a spread state by means of compression springs in a manner known per se, that at least one stationary actuator is provided, the actuator of which is the plunger of a retracted position into its despreading position Haspels to carry out a despreading movement against the force of the compression spring, and that the actuator has a coupling claw into which corresponding coupling elements on the reel shafts can be inserted with play during the rotation of the head plate, so that a positive connection of the actuator with the respective in the Position of the actuator retracted reel can be effected.
  • reels the drums of which are held in a spread state by spring force, makes it unnecessary to carry the actuators with the rotary movement of the reel and the head plate. Only where the coil of tape is to be removed from the reel or slid onto the reel is a stationary actuator required, which is always connected to the feed line via fixed media feeds. To ensure that no forces act on the bearings of the reel shaft in the axial direction and no forces on the bearings of the head plate occur when despreading a reel drum, the reel shaft and actuator have coupling elements that are positively connected before each expansion movement of the actuator and absorb corresponding axial forces.
  • the stationary actuator is arranged in the band collar transfer position.
  • a second, stationary actuator is provided in the area of the starting position that detects the beginning of the tape.
  • the actuator can perform a full de-spreading stroke in the band bundle transfer position, while the actuator in the starting position capturing the band bundle must cause a stroke that only slightly de-stresses the reel drum.
  • the full despreading of the reel drum in the tape bundle transfer position allows the wound tape bundles to be pulled off.
  • the partial despreading of the reel drum in the starting position makes it easier to wind up the beginning of the tape.
  • the first two to three turns are wound with a partially despread reel.
  • the reel drum is then spread so that the initial turns are firmly seated on the reel drum.
  • corresponding bearings on the coupling claw of the stationary actuator take up the rotation of the reel.
  • the steep drives expediently consist of two drive units, namely a despreading drive that can be moved on guides and a displacement drive that moves the despreading drive.
  • the sliding drive can cancel the play provided between the coupling claw and the coupling elements of the reel shafts or can be restored after the despreading.
  • the game is necessary in any case, so that no damage can occur when the reel is moved into a despread position of the stable drive.
  • play would have a disadvantageous effect in the de-spreading movement, since undesirable forces would be transmitted to the reel shaft and the head plate.
  • the advantage here is that the despreading and displacement drive can cancel the play provided between the coupling claw and the coupling element of the reel shaft or, after despreading together with a stop, can be restored to act on the displacement.
  • a further, expedient embodiment of the reversible reel according to the invention results from the fact that at least one reel is assigned a stop for positioning a rolled strip sleeve on the reel drum in accordance with the roll center.
  • Fig. 1 shows a reversible reel 1 according to the invention in its front view.
  • the reversible reel 1 has a head plate 2 with front toothing 3, in which drive gearwheels 4 of motors 5 (see FIG. 2) and a guide wheel 6 engage.
  • the head plate 2 can be rotated clockwise or counterclockwise in accordance with the desired operating mode — winding or unwinding — via the drive toothed wheels 4.
  • the motors 5 can be controlled in such a way that jerky tooth flank changes between the drive gears 4 and the toothing 3 of the head plate 2 are prevented by the uneven mass distribution on the head plate 2.
  • reels 7 and 8 are rotatably mounted, which reach through the head plate 2.
  • the reel 7 and 8 are of the same construction, but the reel 7 is in the starting position in which the beginning of the tape is gripped by wrapping not shown and wound in a few turns.
  • the reel 8, on which there is a completely wound band coil 9, is shown in the band coil transfer position.
  • This drive of the reels 7 and 8 renders rotary drives which are firmly attached to the reels and which have to be supplied with energy by complicated and fault-prone rotary feeds superfluous. At the same time, this type of drive makes the masses to be driven very small.
  • FIG. 3 shows the reel 8 in the band coil transfer position. The reel 8 has been moved into the actuator 18.
  • the reel 8 consists of a reel shaft 19 in which a punch 20 is axially displaceably mounted.
  • the reel shaft 19 has wedge-shaped sliding surfaces 21 on which segments 22 are axially displaceably supported. By axially displacing the segments 22 on the wedge-shaped sliding surfaces 21, spreading movements of the segments 22 forming the reel drum 23 can be brought about.
  • the segments 22 are connected to the stamp 20 via a connecting flange 24.
  • the reel drum 23 is held in the spread state by a compression spring 25 arranged between the reel shaft 19 and the punch 20. By acting on the plunger 20 against the spring force, the reel drum 23 can be expanded.
  • a coupling element 26 is provided at the free end of the reel shaft 19.
  • the clutch element 26 is inserted into the clutch claw 27 of the actuator 18 with play.
  • the actuator 18 has a despreading drive 28 and a displacement drive 29.
  • the despreading drive 28 can be moved back and forth on guides 30 in the direction of the reel 8. The traversing movement is brought about by the piston 31 of the displacement drive 29 connected to the despreading drive 28 via the piston rod 31.
  • FIG 5 shows the reel 8 with a despread reel 23.
  • the piston 33 of the despreading drive 28 has been moved in the direction of the reel shaft 19.
  • the piston rod 34 has axially displaced the plunger 20 against the force of the compression spring 25 and the segments 22 have been moved into the despread position on the wedge-shaped sliding surface 21.
  • the reel drum 23 is spread again by pulling back the piston rod 34 and by means of a stamp 20 which is reset by spring force. Subsequently, the play between coupling element 26 and coupling claw 27 is restored by actuating the sliding drive 29, so that the reel 8 can move out of the band collar transfer position.
  • the sell drives fixedly arranged on the reels must be controlled in such a way that the pistons of the actuators carry out a large stroke in the band coil transfer position and only a small stroke in the starting position. Due to the large stroke, the reel drum must be fully despread so that the coils can be removed. The small stroke only serves to facilitate the winding and fixing of the first turns of the rolled strip on the reel drum.
  • the actuator always executes only a small expansion stroke in the starting position, while the actuator always has to carry out a large expansion stroke in the band coil transfer position. Controls that cause an actuator to have a large stroke and a small stroke are not required.
  • the stop 35 which is controlled by a piston-cylinder unit 36, serves for the positioning of a rolled strip sleeve on the reel drum 23 in accordance with the roll center.
  • FIG. 6 shows an actuator 18 ', which is simpler in construction than the actuator 18 of FIGS. 3 to 5 and can be produced more cost-effectively.
  • the actuator 18 ' consists of a despreading and shifting drive 37 which effects both the displacement movements of the despreading and shifting drive 37 which cancel or restore the play between the coupling element 26 and the clutch claw 27' and the despreading movement of the plunger 20.
  • the piston 40 is acted on in such a way that the piston rod 39 is moved against a stop 38.
  • the despreading and displacement drive 37 is moved on the guide 30 ′ towards the plunger 20. The play between the coupling element 26 and the coupling claw 27 'is restored.
