Definitions

  • the invention relates to a device and a method for winding and unwinding webs.
  • Devices for winding and unwinding webs are known. Often a distinction is made between turret winder and contact winder. Among other things in the EP 1 897 830 A2 is shown a turret winder. The EP 0 270 498 B1 shows a contact winder.
  • Silk winder types have advantages and disadvantages, of which only a few are listed here. Thus, the construction of a Weridewicklers requires considerable mechanical effort, since full winding shafts, which have a considerable mass, must be swiveled. The disadvantages of the contact winders include a long cycle time when changing rolls.
  • the US 5,346,150 B shows a winder with two in the circumferential direction of the contact roller stationary winding shafts. Such a winder, the winding shafts must be removed at various sampling points.
  • a second winding nip can be formed in a winding device, which may otherwise largely correspond to a contact winder, for example, the second winding or the second winding may be used during the winding change
  • Winding shaft are made to the contact roller, while the first (old) winding still winding. This is especially true when the angular positions of the Anwickelspalte differ during Anwickelns. This way you can To make sure that an old and a new reel are not in each other's way. It is possible to dispense with its own drive of the winding shafts and to accelerate the second (new) winding shaft only "at rest" by the employment of the rotating contact roller.
  • one or two driven winding shaft axes make sense, inter alia, if the contact winding principle often negatively striking Einkupplungs- and synchronization errors are to be avoided permanently.
  • Another advantage of the invention is that the winding parameters can be kept very constant when changing.
  • two different adjusting devices can be provided. These can be designed so that they can move their associated winding completely independently.
  • one of these adjusting devices can each be associated with a winding nip or an angular region of the contact roller in which a winding nip can be formed. These angular ranges can be separate from each other, but they can also overlap.
  • an XY traversing unit can advantageously be used in or the Anstellein noise.
  • rollers which have a cutting tool in their outer surface, such as a knife. This engages in the cutting movement on the lateral surface of the roller and cuts through the web.
  • the at least one contact roller is equipped such that it can hold or fix at least parts of the track guided on its circumferential surface. This can be done by applying vacuum to openings in the roll surface, by electrical or electromagnetic forces, or the like.
  • the DE 103 21 778 B4 shows a roller that can hold both a web on parts of its surface, as well as on a Cutting tool that can cut the web orthogonal to its transport direction.
  • the passages of DE 103 21 778 B4 which relate to the maintenance of the web on the roll surface, technical details of the device and process components that cause the holding, as well as the cutting device and its details, are important to the understanding of the present document and are included in the Offenbahrungsgehalt the same.
  • a transport device for the removal of finished coils and / or winding tubes which can be brought into operative connection with the adjusting devices that they can take over winding of at least two of these Anstellvorraumen and / or can transfer cores to this. This can be done in a common (for the at least two adjusting devices) angular range of the contact roller. It is advantageous if the first and second winding nips lie on opposite sides of the contact roller. Then the two or more winding processes are as little as possible in the way. A certain or even an absolute symmetry (eg with respect to a line through the center of the contact roller) has further advantages (eg use of the same components on both sides of the contact roller).
  • a wander of one or more winding nips over the circumference of the contact roller during winding is advantageous.
  • the winding can change its angular position continuously and optionally during the entire winding.
  • This end position may include fixed constraints. Later, the winding can be removed at this end position. In this way, the movement of large (winding) masses can be restricted.
  • two or more winding nips are formed on a winding device, preferably during winding, it is advantageous to move the associated winding to a removal position during the respective winding process.
  • This one removal position can also cover an angular range of the contact roller of 20 °, 30 ° or 45 °.
  • FIG. 1 shows a side view of a winding device according to the invention from its operating side. Therefore, of a part of the device components, only the operation side part can be seen.
  • the device works in FIG. 1 in normal winding operation, which means here that the second web wrap 21 is in an angular position 22 of the contact roller 1, which corresponds to its 21 removal position.
  • the second web wrap 21 is supported by a second winding shaft 5, which is supported by a lower xy adjustment 4.
  • This 4 is articulated as well as the upper xy adjustment 2 on the machine frame, the operator-side shoulder 15 is shown by dashed lines. In this way, it is clarified that this shoulder 15 must be made transparent in order to reveal the view of a large part of the device components shown.

Meanwhile, the already prepared with the winding tube 17 second winding shaft 5 is spent in a "parking position", which is located near the angular position 32, in which later will be wound on it 5.
