Definitions

  • the invention relates to a device for unwinding a material web, in particular a paper or board web, from a roll, for subsequent cutting in the longitudinal direction and for subsequent winding on a plurality of adjacent mailing rolls.
  • the invention also relates to a method for unwinding a material web, in particular a paper or board web from a roll, in particular for subsequent cutting in the longitudinal direction and for subsequent winding on a plurality of adjacent shipping rolls.
  • Such a device is known in the art and is used for unwinding a web of material, which is then cut by one or more cutting devices in the longitudinal direction and divided into individual webs, to coincidewickeit then on cores to so-called Varsandrollen.
  • Carrier roll winding machines have two driven carrier rolls, on which the winding rolls rest during winding next to each other with aligned sleeves.
  • the carrier roll winding machines have a Roflenaus tenuvorides that emit a set fertiggewickeiter winding rolls from the roll bed formed by the two support rollers at a roll change. The finished set of winding rolls is thereby pressed by the ejection device on the crest of a support roller away on a lowering platform.
  • the winding drum i. H. the winding roll, regeneratively braked.
  • From the EP-A-1792859 is a method for changing Tambouren in a roll winding device, in which at the end of a winding sequence a web of material (2) donating and driven drum is delayed until it stops, then the resting web is severed in the reel winding device and then a new, from a new Tambour dispensed material web is introduced into the roll winding device, wherein a beginning (8) of the new material web by means of an auxiliary device in a predetermined width, in particular in full width, is subtracted from the new spool.
  • a secondary drive is coupled to the driven by a prime mover drum that the primary drive is uncoupled from the drum and preferably decelerated to a stop that at the same time, at least overlapping in time or thereafter the driven by the secondary drive spool is brought from a main unwinding position in a Endabwickelposition that then the new, carrying the new material web spool in the Hauptabwickelposition brought and the prime mover is coupled, then that the auxiliary device subtracts the beginning of the new material web in a predetermined width, in particular full width of the new spool and moves to a waiting position for the upcoming web feed that at the same time, at least overlapping in time or thereafter the moving drum is decelerated to a standstill with the aid of the secondary drive, that thereafter the resting material web is severed in the roll winding device, that subsequently the new material web delivered by the new drum is introduced into the roll winding device by means
  • This object is achieved in a device having a first and a second unwinding position in which the web is successively unwound from the roll, wherein the web in the first unwinding position by a first drive and in the second unwinding position by a second drive of the Winding roll is unwound.
  • the invention makes it unnecessary to install a high drive power; At the same time, costs can be saved.
  • the first drive in relation to the second drive allows high torque.
  • the first drive comprises a motor and a gearbox interposed between the motor and the winding roller at the first unwinding position.
  • the transmission can shift to a lower gear stage. If the diameter of the winding roll or the drum has reduced so far that this can be taken from the engine, which is arranged regularly at the second unwinding position, then this is engaged at the other end of the winding roll.
  • the switching between the two motors is preferably carried out during the set change; ie, when a set of shipping rolls is finished wound from the strips of unwound web.
  • the second drive allows a high speed in relation to the first drive.
  • means for sucking, separating and / or splicing the web in the area between the two unwinding positions can be installed.
  • the method is characterized in that the winding roll is unwound by the first drive until a set of shipping rolls has arisen.
  • the second drive is moved from the second position to the first position as soon as a roller present in the first position is completely unwound.
  • the second drive is coupled to the shaft of the roller opposite the first drive in the first unwinding position.
  • the second drive serves as a drive.
  • roller after being unwound to the predetermined extent, is moved together with the second drive to the second unwinding position and from this to the end is handled.
  • a web 6 is unwound during the unwinding of the full winding roller 3 at the first unwinding position 2 by a first drive 5.
  • the material web 6 is guided past a splicing device 7.
  • the winding rollers 3, 4 are respectively via bearings 8, 9 and 10, 11 at least substantially in one plane on a support device 12th Simultaneously with the still full winding roll 3 (full tambour, "mother roll"), the winding roll 4, which is already substantially unwound, unwound in the winding position 2 by a second drive 13 to the end of a web 14, via a guide roller 15 and a splicer 16 is passed over.
  • the second drive 13 is dimensioned by its power so that its drive motor for generating a small torque just sufficient to allow the remaining processing of the web 14 of the winding roller 4 in the unwinding position 2.
  • the first drive 5 is dimensioned such that its torque is sufficient to unwind the material web 6 from the still full winding roller 3. The winding roll 3 is thereby unwound by the first drive 5 until the first set of shipping rolls (finished rolls) has arisen.
  • the first drive 5 may include a motor and a switched between the winding roll and the engine gear instead of a high torque motor having two or more switching stages and switches depending on the diameter of the winding roll in the corresponding switching stage, so that the engine always is loaded with an approximately equal load by the torque of the winding roll.
  • a further step is, shortly before the web 14 is unwound from the winding roll 4, this separated by (not shown) separating or - cutting device to connect an end 17 of the web 14 with a beginning 18 of the web 6.
  • This is therefore guided by the splicing device 7 in the direction of an arrow 19 in the vicinity of the splicing device 16 and connected by means of at least one adhesive strip or glue with the material web 14.
  • the winding roller 4 is now ready to be lifted out of the unwinding position 2.
  • next step For this purpose, first the second drive 13 is pulled out of a coupling, which is arranged in the region of the bearing 11.
  • the second drive 13 is moved in the direction of an arrow 20 to the winding roller 3 in the unwinding position 2; There he is coupled together via an integrated coupling in the region of the bearing 9 with the winding roller 3.
  • the winding roller 4 is removed from the unwinding position 2 in the direction of an arrow 21.
  • this is still driven by the first drive 5, as required according to the winding circumference of the winding roll 3.
  • the unwinding position 2 is initially empty. Now that the first roll of shipping rolls has been finished, a first change of set takes place, ie the single sheets are separated, the litter is ejected and the new web starts are fastened to a new set of tubes.
