Definitions

  • the invention relates to a device for winding material webs on winding shafts with a movable bearing holding a winding shaft during winding, by means of which the winding roll which forms can be set against a contact roller and which can be moved into a position remote from this for removing the completely wound winding roll, and with a device for inserting a new winding shaft, for example accelerated to the speed of the web, onto which the beginning of the web formed by a separating cut is wound into the movable bearing.
  • a known from DE-PS 32 12 960 combined contact and central winder of this type has a pair of pivoting about the axis of the contact roller receiving arms that receive a new winding shaft in a vertical position, which after accelerating to web speed by a pair of friction wheels Winding the web beginning separated by a separating cut is lowered onto the contact roller rotating at the same peripheral speed. Then the pickup arms around pivoted about 90 ° so that the shaft journals of the winding shaft can be inserted into the receptacles of a carriage which moves away from the contact roller in accordance with the growing diameter of the winding roll which is being formed. After making the separating cut, the carriage is then moved away from the contact roller to such an extent that the finished winding roll can be lifted out.
  • the carriage then moves back towards the contact roller, so that the receiving arms can insert the journal of the winding shaft into the receptacles of the carriage.
  • the winding shaft is supported on the contact roller with the winding roller forming on it until the wound winding roller is lifted out of the carriage and the carriage is moved back into its receiving position close to the contact roller, so that it moves in this Time at the high winding speeds has already formed a winding roll with such a large weight that damage to the web can occur due to the contact pressure.
  • the weight of the winding roll that is formed can result in damage to this foil, which leads to rejects.
  • there may be disturbances in the web tension if the friction wheel drive, which is active until the newly wound winding shaft is in the slots in the carriage, is switched to the central drive of the winding shaft (switching the drives for large winding diameters).
  • the object of the invention is therefore to provide a device of the type mentioned, which ensures that the newly wound roll can be wound quickly after winding under defined winding conditions in order to reliably avoid damage to the web to be wound up during winding.
  • this object is achieved in a device of the generic type in that the movable bearing is formed by two pairs of holding devices, each pair of which can be moved both synchronously with the other and independently of the other, and in that the pairs both have one A winding roll or a winding shaft with a wound web start are able to hold the winding roll as well as on its own.
  • divisible receptacles or bearings are thus provided for the shaft journals of the winding shaft, which, when moved together, jointly carry a winding roll which is being formed and which can be separated and moved apart in such a way that a pair releases the completely wound winding roll for removal while the other pair moves to the take-up position near the contact roller.
  • the pairs are then moved together again in such a way that the receptacles of both support the shaft journals of the winding roll that is being formed. Since one pair of the cooperating receptacles travels the completely wound winding roll while the other pair of receptacles moves into its receptacle position close to the contact roller for receiving the new winding shaft, the winding shaft can be taken over from the receptacles as soon as the new start of the web has been securely wound onto it is. The transfer of the new winding shaft with the web start wound onto the receptacles of the one pair of holding devices can thus already take place at a time when only a few turns are wound. At this point, the winding process necessary for the material to be wound can be set so that sensitive material to be wound can no longer be damaged. There are thus advantages in both central and contact winding.
  • the receptacles can be arranged on carriages which can be moved together and independently of one another.
  • the holding devices are expediently located at the upper ends of pairs of levers which are mounted pivotably about a common axis and are provided with separate pivot drives.
  • the holding devices can consist of U-shaped receptacles, of which the legs, which face one another when the receptacles have moved apart, are designed to be retractable and extendable. If the legs are extended, receptacles are formed in each case, which are capable of separately storing the journals of winding shafts. If the legs are retracted, the receptacles can be moved against each other in such a way that the outer legs form the boundaries of a common receptacle.
  • one of the receptacles of the two pairs of receptacles is provided with a driven shaft having a coupling half, which can be coupled to the other coupling half provided on a shaft journal of the winding shaft. In this way, the central drive of the winding roll can be effected.
  • pivot plates provided with a rotary drive are mounted on the flange above the shaft journal of the contact roller, the bearings for receiving a new winding shaft and for the transfer thereof have the receptacles of a pair of holding devices.
  • the bearings are expediently provided on a linkage which is guided in a longitudinally displaceable manner on the swivel plates.
  • the rods are provided with a translatory drive.
  • the bearings expediently consist of bowl-shaped ones Recordings in which the pins of the winding shaft are held by swivel plates fixed abutments.
  • FIG. 2 shows the roll changing system swung up under the prepared winding shaft 36.
  • FIG. 3 shows the device in a state in which the new winding shaft is lowered and locked in the receptacles 13, the winding shaft not yet having any contact with the contact roller or film web.
  • the drive of the winding shaft is accelerated to web speed via the friction wheel drive.
  • Figure 5 shows the swiveling of the full roll outwards Transfer of the role from the outer pair of arms to the inner pair of arms.
  • the outer, empty arm pairs pivot in the direction of the contact roller.
  • the reel change system swivels with the new winding shaft to transfer the winding shaft to the outer pair of arms.
  • the roll changing system is in the rest position.
  • the machine frame of the winding device consists of two side frames 1, which among other things. are connected to each other by a traverse 2.
  • FIG. 1 shows a shaft 3 mounted in the two side frames, on which a contact roller 4 is firmly attached.
  • the shaft On both sides next to the contact roller 4, the shaft carries a bearing 5, which is freely rotatable on the shaft 3.
  • both a plate 6 and a disc 7 are firmly connected.
  • the disks 7 are connected via chains 8 to drive disks 9, both drive disks 9 being assigned a servomotor (not shown).
  • the plates 6 have projecting parts which carry a freely rotatable guide roller 10. Further freely rotatable guide rollers 11 are arranged on the plates 6 to one another so that they form a guide path for an angled lever 12 assigned to each plate 6. Each of these levers has a receptacle 13 to which an abutment 14 is assigned.
  • the angled levers 12 can be moved via a piston-cylinder unit 15 are moved back and forth in the direction of arrow A.
  • Piston cylinder units 16 and 17 are assigned to each side frame 1, the piston cylinder units 17 engaging on outer swivel arms 18 and the piston cylinder units 16 on inner swivel arms 19. Both swivel arms are mounted on a shaft 20 which is held by the side frames 1.
  • the shaft 20 is led outwards from the left-hand side frame, a pulley 21 being firmly attached to the left-hand end of the shaft 20.
  • This pulley 21 is connected via the belt 22 to a further pulley 23 which is seated on a short shaft piece 24.
  • This shaft piece 24 is mounted in a bearing block 25 which is connected to the left outer pivot arm 18 via a holder 26.
  • the shaft carries a coupling half 27 which, in the position shown in FIG. 6, is connected to a further coupling half 28.
  • This coupling half 28 is part of each winding shaft 29.
  • both the outer and the inner swivel arms 18, 19 have receptacles 30, to which movable latches 31 and 32 are assigned.
  • FIG. 1 shows the situation in which a winding roll 33 lies laterally against the contact roller 4 and has the desired number of layers of the web material 34.
  • the winding roll 33 is by a motor which is only indicated schematically 35 driven via the pulley 21, the belt 22 and the pulley 23. It is supported in both the inner and the outer swivel arms 18 and 19.
  • the plate 6 is now pivoted counterclockwise via the drive disks 9 (see arrow direction B) until the plate assumes the position shown in FIG.
  • the material web 34 is partially lifted off the guide roller 10 from the contact roller 4. In the position shown in FIG.
  • the receptacle 13 of the angled levers 12 are located below a winding shaft 36 prepared with adhesive strips, the angled lever 12 being extended via the piston-cylinder unit 15.
  • the prepared winding shaft 36 is lowered into the receptacles 13.
  • the winding shaft 36 is then supported in the receptacles 13 and is held there by the abutments 14. It can be clearly seen that the winding shaft 36 has no contact with the web 34 in the position shown in FIG. 3. At this moment, the winding shaft 36 is accelerated to the speed of the contact roller 4 via a friction wheel drive (not shown) and then lowered onto the contact roller via the angled lever 12. This lowered position can be seen in Figure 4.
  • the web 34 is separated by the knife 37. Due to the adhesive strips on the new winding shaft 36, the beginning of the web 34 adheres to the new winding shaft and is wound onto it. Immediately afterwards, the completely wound roll 33, which is held by both receptacles 30 of the swivel arms 18 and 19, is transferred to the inner swivel arm pair 19. For this purpose, the bolt 31 of the outer pair of swivel arms assigned to the receptacle 30 moves in and thus releases the roller.
