Definitions

  • the invention relates to a roll cutting device for a material web with a cutting station for Cutting the material web into partial webs and a winding station for winding the partial webs into partial web rolls, wherein the winding station at least two winding position groups at a distance from each other and has winding units arranged on a gap, and with a guide device for the partial webs between the cutting station and the winding position group.
  • the invention is intended to be based on a paper web are explained as an example of the material web. she but is not limited to paper webs.
  • Such a roll cutting device is known from US 3,847,319 A. known.
  • a web of material is cut into relatively narrow strips cut.
  • the strips are divided into two groups, where in the first group the even numbers and in the second group the odd-numbered strips are arranged.
  • the Stripes in a group are marked by one at a time Part of a control device detected and with this part Winding station fed.
  • EP 0 315 569 A shows a further device of this type.
  • the Material web is made with the help of a guide tube guided on chains passed through the entire roll cutter, so also through the cutting unit.
  • the cut partial webs are then in a configuration on a first suction roll sucked tight.
  • a second guide rod comes into action, at the beginning of the partial lanes at a certain distance can also be sucked in behind the first rod.
  • the partial webs that do not continue with the help of the first suction roll are wound, are severed by hand. If the second Guide rod is moved away, it only detects the separated Partial webs and can be used to abut a second suction roller bring.
  • DE 36 07 136 C1 shows a device for winding at least a tape on a reel. It is about a metal strip that is passed through a slitter and then to be wound up on reels. To individual Feeding strips to the wraps, guide tables are provided, on which the individual strips under the action of gravity can slide down. The control tables point to their protruding parts beyond a pivot point, which are intended to catch the leading ends of the partial webs.
  • Paper webs are often produced in widths that are larger than a processor needs. Have so modern paper machines working widths in the order of magnitude up to 10 m. Printers and other processors however require paper web widths of the order of magnitude from 0.4 to 3.8 m.
  • the corresponding partial web rolls in feeding the winding position groups is one Guide necessary.
  • the control device must in particular at the beginning of the wrapping process that the corresponding partial web is also the "correct" Winding position is fed.
  • Such guidance devices are known per se. Their job is side by side lying partial webs in different To lead directions.
  • the slitter rewinder should be trained that they part web roles with changing Can generate widths. This is not only a requirement, that the knife in the cutting station accordingly the desired widths of the partial web rolls be moved. They also have to be in the changing station Winding units aligned accordingly in the width direction so that the partial webs with as little as possible Effort can be wound up.
  • the Change of role program i.e. changing the Widths of the partial web rolls is therefore considerable Associated effort. Flexible production is required however this possibility because not all customers want exactly the same roll widths.
  • the invention has for its object a change to facilitate the role program.
  • This task is done with a roll cutter of the type mentioned in that the Guide device transverse to the running direction of the partial webs in is divided into several zones, each of which can be activated individually are.
  • control device i.e. guide means to shift in the width direction or their working width to change.
  • the guidance device can rather over the entire width of the material web, that is across the width of a jumbo or parent roll. Your adaptation to the individual widths of the partial web rolls then takes place in that the guide device is activated only in the latitudes where it necessary and desirable for the individual web roll is.
  • the control device is divided into zones, which can then be activated individually and in particular are narrow. So when you get a partial train in wants to lead a corresponding direction, only the zones activate the guidance device assigned to this sub-lane are. If the width and / or the position this sub-lane changes, you become more or less or activate other zones so that without a mechanical Reconstruction of the control system, the management of the corresponding Partial web is ensured.
  • the guide device for each winding position group has a path and at least via the Width of the material web the zones of one path each can be activated to complement the zones of the other path are.
  • a zone group is active is to guide the partial path in the one path, i.e. the winding position in the one winding position group then the corresponding zone group not active in the other path, i.e. a web guide this path is excluded.
  • the guide device preferably has a pneumatic one working switch following the cutting station on.
  • the "fanning out" of the partial webs, i.e. leading neighboring sub-lanes in different directions, is controlled via this switch.
  • the pneumatic mode of operation allows easy control. airflows are known to be very easy on and with the help of valves remedy.
  • the guide device advantageously has air baffles on.
  • the air baffles guide the partial webs "Air cushions" so that they are at least partially non-contact be worn, especially in a straight line running track sections, which protects the Partial tracks contributes.
  • the air baffles can also be in zones can be controlled, which makes air consumption small holds. Of course, that does not preclude the partial lanes are guided over pulleys on which they rest. Lighten between the individual pulleys the air baffles but the automatic guidance. A manual threading of the partial webs, which is due the usually larger number of partial webs difficult, can be omitted.
  • At least parts of the air baffles are advantageous pivotable. This is particularly beneficial if the course of the web changes in the course of the winding process. Such a constellation then occurs, for example on when the winding core of the partial web rolls is practical remains stationary and the increasing diameter of the Partial web rolls to a changing point of impact of the partial web leads to the partial web roll.
  • the width of the zones is advantageously less than that Width of the narrowest part web roll. You know in advance usually what widths on the slitter should be processed. If you now the Width of the zone to the smallest width of the partial web rolls adjusts, it is ensured that all partial webs on the desired way can be processed.
  • the zones are 200 to 300 mm are wide. Because the narrowest part web rolls usually can have a width of 400 mm Ensure the processing of all partial web rolls.
  • Zones in which an edge of the partial web is advantageous runs partially activatable.
  • activation of the Guide device is cheap or even desirable. In other areas, however, would be an activation harmful.
  • the "switch" only the partial lanes in the different directions conduct. It is sufficient if an area in the middle (seen in the width direction) of the partial webs is applied.
  • the edges can be left out, because here is an application by an overarching Zone of the control device would cause that also the neighboring part of the same zone still affected and the wrong one Direction would be applied. In such a case you would disable the overlapping zone altogether, "switch off" for both paths.
  • the cutting station has cutting devices whose Position transverse to the direction of the web of one Control device is changeable, the control device is connected to the control device and this depending on the position of the cutting device controls. In this case you come with one only control unit. This has besides the simplification of the apparatus structure also a simplification operation.
  • the cutting program i.e. the Width of the individual web rolls, only once can be entered.
  • the control device is positioned then the knives in the cutter and sets at the same time it determines which zones of the control system are active, are inactive or partially active.
  • a roll cutting device 1 has a cutting station 2, in which a material web 3 into several partial webs 4, 5 is cut. The cut is made here in the longitudinal direction, so that the partial webs 4, 5 a have reduced width compared to the material web 3. The sum of the widths of the partial webs 4, 5 corresponds then the width of the material web 3.
  • Fig. 1 shown in an almost completely wound condition. With solid lines the state is at the beginning of the winding process shown.
  • the Partial webs 4, 5 on roll cores 8, 9 or winding tubes attached.
  • the winding tubes are in turn in support arms 10, 11 stored and driven there. It deals center winders.
  • Pressure rollers 12, 13 are provided for the construction of the partial rollers, which rest on the circumference of the partial web rolls 6, 7 and with increasing diameter of the partial web rolls be moved.
  • Each web roll 6, 7 is arranged in a winding position. There is one in each winding position Winding device that ensures that the partial web roll 6, 7 is wound.
  • the winding positions are in Winding position groups 14, 15 arranged. In each winding position group 14, 15 are the axes of the partial web rolls 6 or 7 practically on the same straight line.
  • the individual partial web rolls have in each winding position group a certain axial distance from each other.
  • the partial web rolls of the two winding position groups 14, 15 are spaced from each other, i.e. in the area where in a winding position group 14 There is a space between adjacent partial web rolls is in the other winding position group 15 a partial web roll.
  • the Guide means for each winding position group a path.
  • the two paths are essentially symmetrical trained to each other.
  • the guide device includes behind the cutting station a pair of blowpipes 16, 17.
  • the two Blow pipes 16, 17 together form a pneumatically working Turnout, the function of which is explained below will be.
  • Air baffles then follow in each path 18, 20, 22, 24, 26 and 19, 21, 23, 25, 27, of which a part 20, 21 is pivotable about which the To be able to follow winding changing path.
  • Further deflection rollers 28, 30, 32 and 29, 31, 33 are provided.
  • the guiding device is now transverse to the running direction of the material web 3 divided into relatively narrow zones.
  • each Zone has a width in the range of 200 to 300 mm.
  • the smallest part web width that are produced here can be 400 mm.
  • the air outlet can be omitted in the individual zones the blowpipes 16, 17 and from the air baffles 18 to control each independently. This is to be explained with reference to FIG. 2.
  • the individual zones have the atomic number 1 to 14 provided. If the blow pipe 16 or the air baffle 20 blows air in a zone, this is with marked with a "+”. If no air is blown out is marked with a "-".
  • Zones of the blowpipes 16, 17 work complementarily, i.e. if zones of the blowpipe 16 are active, then are the corresponding zones of the blowpipe 17 on each Case not active, i.e. they do not generate blowing currents. In zones that overlap an edge of partial web 4, 5, none of the two blowpipes 16, 17 produces one Airflow. Zones 5, 10 are in the exemplary embodiment 2 is not active.
  • zones 5, 10 which are the edges of partial webs 4 overlap, active. This hurts nothing, because the corresponding neighboring sub-track 5 in Area of the air baffles is no longer available. If you activate the corresponding zone 5, 10, then partial web 4 is supported over the entire surface.
  • the entire control system only has to be active before the actual winding process Partial webs 4, 5 to the winding cores 8, 9 of the individual To manage partial web rolls. As soon as the partial webs 4, 5 their respective roll cores 8, 9 are attached guidance only via the deflection rollers 28-33.
