Definitions

  • the invention relates to a winding device for a Material web, in particular for a roll cutting device, according to the preamble of claim 1.
  • Such a winding device is from GB 2 162 157 A. known.
  • the winding cores are gripped by grippers, which are arranged on the holding arms, and with them to rest on a lying on a support drum Material web pivoted. There can journal be inserted into the winding tube.
  • the invention is based on a paper web explained as an example of a material web. she is but not limited to this.
  • a winding tube for example is made of cardboard.
  • the finished roles have here a width in the range of 0.4 to 3.8 m. Your diameter is often less than that of so-called jumbo rolls, that at the exit of a paper machine or after of the satin. It is in the range of 0.3 to 2.0 m.
  • finished roles are often generated by the paper web of the jumbo or parent roll unwound, cut and then wound up on the roll core.
  • the web length of a jumbo roll is usually sufficient for several finished rolls.
  • the winding device is part of a roll cutting device is because after reaching the desired diameter of the finished rolls a variety of new winding cores.
  • GB 2 136 403 A describes another winding device for a slitter winder with new winding cores can be stored in a holder.
  • the keeper is located at the top of a lifting device, the arranged in the foundation of the winding device is.
  • the holder can be raised with the lifting device until the winding sleeve reaches the position of the journal reached.
  • DE 23 52 685 A shows a transfer device for a Roll winder, with a tube holder for new Winding sleeves arranged at one end of a swivel arm is.
  • the sleeve receptacle has a locking device on the one hand and a belt around the other on.
  • the belt is around several roles guided and serves to wind the first layers of the Press the material web tightly against the circumference of the spool.
  • GB 2 271 345 A shows a web winding machine in which the individual winding positions on a rotating Disc are arranged. By turning the disc you can a full winding roll twisted into a dispensing position be, at the same time a new winding tube in a Winding position is moved. In this winding position can a hood-shaped guide device around the winding tube be placed, with blowing agents provided, around the beginning of the material web around the winding tube to blow.
  • BE 691 439 A describes a winding machine in which Winding rolls on two sides of a central support roller be wrapped. The winding rolls are thereby Holding arms worn, which move away from the backup roller can if the diameter of the winding rolls is larger becomes.
  • the invention has for its object the change to facilitate the roles.
  • a winding tube for a subsequent one Roll to be wrapped can be placed on the tray become.
  • the carrier shell at least on each arm as long as a larger axial extension than has the bearing journal, like the bearing journal still are not inserted into the winding tube, the Stay arms moved apart in the axial direction, without the winding tube falling off the carrier shell. You can definitely on the axially over the Bearing journal protruding end are kept.
  • the holding arms take the finished roll have moved to a position in of them when the holding arms move together or just the bearing journal can be gripped by the bearing journal.
  • the trunnions can be replaced by a own movement and / or when moving the holding arms together into the winding tube lying on the carrier shell be retracted.
  • the transfer process is therefore practical completed.
  • the spreading of the holding arms or withdrawing the trunnions to deliver the finished one Role is necessary anyway.
  • the carrier shell does not meet only the function of closing the winding tube to the bearing journal transport. It also makes it easier to put on the Beginning of the material web to be wound on the winding tube. In this case, the carrier shell remains not just in the bearing journal area until the Winding sleeve is received by the bearing journal. she remains a little longer, namely until the material web is brought into contact with the winding tube has been.
  • the holding arms from a winding position in which they are essentially vertical, in a storage position are pivotable, the recording position the support shell is adjacent to the pivot point. If the holding arms are vertical in the winding position, then they are easily able to do that with increasing winding diameter increasing weight of the roles to bear. The storage of the finished rolls then takes place in a different position, so that the removal the reels the winding process of a subsequent one Role not hindered. Because at the same time the shooting position the support shell adjacent to the pivot point is, the loading of the tray with the Winding core of the subsequent roll relatively early take place, i.e. under certain circumstances, if the Holding arm is still in the storage position. This shortens the changing times.
  • the pivot point is preferably in the direction of gravity arranged below the journal. In normal operation then only act on the holding arm Compressive forces.
  • Each holding arm advantageously has a tray drive which can only be activated if the Holding arm is in the winding position. This ensures that a transport of the winding tube in the Winding position can only take place if the holding arm is actually able to immediately afterwards to start the wrapping process. It also has this configuration has the advantage that the sleeve with high Reliability remains on the trays and not by changing the position of the support shell in the Space, such as when pivoting the Holding arms would take place, falls from the carrier shell.
  • the recording position is advantageously the lower end arranged adjacent to an inclined surface.
  • the winding sleeve of the carrier shell can then be inclined are fed.
  • the inclined surface can in particular with a roll cutter over the entire Extend width so that when there is a change the widths of the individual partial webs and the associated ones Change of position and width of the partial web rolls is still able to meet the individual Winding sleeves of the carrier shell or the pair feed from trays.
  • the inclined surface is provided with a pawl. You can then Transfer of the winding tube from the inclined surface to the Control the tray.
  • Such a sleeve feeder can consist of a magazine. But it can also be formed by a dolly be driven to the top of the sloping surface can be. From there, the winding tube can simply be opened the inclined surface are given.
  • the guide device is designed as an air baffle. It is enough here off when the air baffle on the material web in Area of the edges. Since the carrier shell anyway protrude beyond the axial extension of the trunnion must result at the edges of the material web Strip that is wide enough to effect the lead to be able to. The air baffle then blows the beginning of the Material web, so to speak, around the winding core, so that the winding process can be started relatively quickly can.
  • a winding device 1 has two holding arms 2, 3, that with the help of a schematically shown swivel drive 4 from an essentially vertical position, which are shown in Fig. 1 with solid lines can be swiveled into a position in which a wound roll 5 placed on the floor 6 can be, as shown with dashed lines in Fig. 1 Lines for the roll 5 is shown.
  • the role moves itself with its center along the double arrow 7.
  • the holding arms swivel about pivot points 8th.
  • the roll 5 has a winding tube 9 as the roll core on.
  • the winding tube 9 is a Mandrel 10 connected to a rotary drive 11 is rotated and pulls a material web 12 on himself.
  • a pressure roller 13 ensures one controlled construction of the role.
  • the two holding arms 2, 3 are in the direction of the double arrows 14, 15 movable. Especially if the Winding device 1 in a roll cutting device is used, the holding arms 2, 3 are thereby individual controllable. This not only allows their axial Position, i.e. the position in the direction of the double arrows 14, 15, but also the distance of the Holding arms 2, 3 to each other, so that different widths Rolls can be wrapped.
  • the holding arm 3 has a bearing pin 16 which the Mandrel 10 is opposite.
  • the mandrel 10 and the journal 16 can be of opposite Directions are inserted into the winding tube 9, if the holding arms 2, 3 are moved towards each other.
  • the bearing pin 16 can also be designed as a mandrel and be driven.
  • the two trays 17, 18 can be from a lower position, which is dashed is drawn in an upper position, the is drawn with solid lines become. For this they have a not shown Drive on.
  • This drive can, for example be formed by a spindle system.
  • the lower position which is near the pivot point 8 is arranged (see Fig. 1), serves as the receiving position.
  • a winding tube from an inclined surface 19, where it with the help of a pawl 20 is held in the support shells 17, 18th roll.
  • Fig. 1 there are several winding tubes in different Positions shown.
  • Another winding tube is located on a carriage 21 on upper end of the inclined surface 19, which is used to supply the Serves winding sleeves.
  • the support shells 17, 18 have a larger axial extent than the clamping bolt 10 and the bearing pin 16, i.e. they protrude over the clamping bolt 10 or the bearing journal 16 in the axial direction. It is possible that the winding tube 9 is indeed on the trays 17, 18 rests and from the receiving position be moved to the transfer position (upper position) can without the clamping bolt 10 and the bearing pin 16 to be hindered. If the support shells 17, 18 their Have reached the transfer position, then the two holding arms 2, 3 are moved towards each other. Here, the clamping bolt 10 and the bearing pin 16 moved into the winding tube 1. The winding tube 9 slides on the trays 17, 18, what without Problems is possible. If the winding tube 9 between the two holding arms 2, 3 on the mandrel 10 and the Bearing pin 16 is clamped, the support shells 17, 18 move down again.
  • Fig. 1 it is shown that the support shells on extend the feed side of the material web 12. she form an air baffle 22 there, which facilitates to guide the material web 12 around the winding tube, so that the wrapping process started almost automatically can be.
  • the support shells 17, 18 such air baffles 22nd have, then the support shells 17, 18 in the Transfer position (upper position) until the winding process has begun. Then they are lowered. in this connection the air baffles 22 can be folded away if necessary so that they do not get caught on the winding tube. If the air baffles 22 are missing, the Carrier shells 17, 18 are already lowered when the winding sleeve 9 between the mandrel 10 and the bearing journal 16 is suspended.
  • the drive of the support shells 17, 18 can be designed in this way be that the support shells 17, 18 only from their Recording position can be moved to the transfer position can when the holding arms 2, 3 are in their winding position located, i.e. standing vertically. In this situation it is ensured that the trays after closed at the bottom and practically only open at the top are so that the winding tube 9 cannot fall out.
