  • the invention relates to a cutting system for a material web consisting of an unwinder, a downstream, as Dancer unit serving intermediate storage and a downstream Cutting frame with a cutting unit arranged thereon, wherein over the longitudinal direction of the cutting frame to a laterally extending Rail guided, extending parallel to the cutting unit Gripper bar is movable.
  • Such a cutting system is known from use, at which is just a gripper bar over the length of the cutting frame movable between a front position and a rear position is.
  • the gripper bar engages in its front position suitable receiving means the end of the in the dancer unit cached material web and pulls it through procedures along the rails attached to the cutting frame over the Cutting table.
  • the gripper bar stops in the cutting position because due to the usual cutting technique, the material is only at a standstill can be cut. Then the gripper bar spends that cut piece of the material web to a below the Discarding stack, after which the gripper bar returns to its foremost position to the following Cycle.
  • the known Machine arrangement associated with the disadvantage that because of required unproductive return stroke of the gripper bar Capacity of the cutting system even with larger ones Travel speeds of the gripper bar is limited.
  • the invention is therefore based on the object, the capacity of a Increase cutting system with the features mentioned at the beginning.
  • the basic idea of the invention is a cutting system of type mentioned above, in which at least two gripper bars are movable along the cutting frame and each gripper bar one side of a first holding tower that can be moved on the rails is worn and at its opposite end a telescopic has extendable extension piece, which on a opposite second passengers Holding tower is dockable, and the holding towers become one Height adjustability of the gripper bar carried in each case is set up are such that each gripper bar moves along the Cutting frame can run over the other gripper bar.
  • the cycle time for the Cutting process can be significantly reduced because during the Cutting stage of the first gripper bar the second Gripper bar already in its receiving position for the end the material web is movable.
  • the two work Gripper bar in constant change.
  • the traversing movements are excluded because the gripper bar on the one hand are adjustable in height so that the gripper bar can run over or under each other; because on the other hand also in Drive the respective holding towers past each other must be axial according to the invention Extension option for the respective gripper bar provided, the required length compensation when connecting to a to train the assigned outer holding tower.
  • the Gripper bar in its lowered position on his him bearing first holding tower opposite end on a bearing on sledges; because of this support is a exact positioning of the gripper bar with regard to gripping given the end of the material web.
  • the gripper bar is according to one Embodiment provided that the two gripper bars arranged first and second holding towers and the sledge each side reversed to each other on different sides of the Cutting table are arranged.
  • the two gripper bars arranged first and second holding towers and the sledge each side reversed to each other on different sides of the Cutting table are arranged.
  • Three rails for receiving on both sides of the cutting frame a first holding tower and a second holding tower and one each Slides are arranged.
  • the sledges are each on the innermost rails and the associated gripper bar load-bearing first holding towers can be moved on the middle rails, while each for docking the extension piece of the the relevant gripper bar set up second holding towers on the outermost rails are movable.
  • first and second holding towers each a lifting device for moving those carried by them Gripper bar between a lowered position and one have raised position.
  • the second holding towers and / or the A docking device ends of the extendable extension pieces for detachable connection of holding towers and extension pieces have, according to an embodiment of the invention it can be provided that the second in each case as a docking device Holding tower protruding in the axial direction of the gripper bars Has pin on which the respective extension of the Gripper bar with a hole formed at its end is positively open.
  • an improvement of the dancer unit is provided by a controlled Preload of the dancer unit should be adjustable.
  • the dancer unit from one Number of stationary first deflection shafts and a number of in one arranged movably with respect to the stationary deflection shafts was found at the known cutting systems only control the bias by the weight of the sled with the second ones stored in it Deflection waves instead.
  • the movable carriage by means of a motor is movable, so that a controlled bias for the material web is adjustable.
  • the cutting system shown as a whole in FIG. 1 initially exists from an unwinding unit 10, in which a supply of the material to be cut Material web is housed. As not shown further, is from the Unwinding unit, which is a material web with constant Pull-out speed provides a material web over the downstream dancer unit 11 performed, which serves as a buffer and will be described separately later. From the dancer unit is the material web is guided to the downstream cutting frame 12, along it on two laterally arranged rails 14 two gripper bars 15 and 25 are led, which are set up to join them trained receiving devices 16 the end of the material web capture and bring into the cutting position in which it is from the Cutting unit 13 is cut. The cut off part of the Material web can from the gripper bar 15 or respectively attacking 25 will be moved a bit and will not on one shown stacked, which is between the rails 14th located.
  • a first gripper bar 15 provided with a holding device 16 is first firmly attached to and supported by a first holding tower 17, this holding tower being movable on a middle rail 18 by three rails 14 arranged next to one another.
  • the first gripper bar 15 extends to the opposite rail arrangement 14 and is supported here on a slide 20 which runs on the innermost rail 19 and can be moved together with the first holding tower 17.
  • the first gripper bar 15 is in a lowered, lower position.
  • a second gripper bar 25 is also fastened to and supported by a first holding arm 27 guided on the middle rail 18 of the rail arrangement 14, the arrangement of the first holding arm 27 for the second Grapple bar 25 in comparison with the described arrangement of the first gripper bar 15 with the associated first holding tower 17 is struck laterally.
  • the second gripper bar 25 To move the second gripper bar 25 on the first To enable gripper bar 15 is the second Gripper bar 25 in a raised position by one on the first holding tower 27 trained lifting device 30 in the upper Position has moved.
  • the second Holding tower 28 To on the opposite side To create abutment is from the second gripper bar 25 in this telescopically arranged extension piece 23 extended and to one on the outermost rail 22 of the rail assembly 14 movable second holding tower 28 docked, the second Holding tower 28 provides the same height position as that first holding tower 27 for the second gripper bar 25.
  • In this raised position is the second gripper bar 25 with its him supporting first holding tower 27 facing away from the end assigned carriage 20 lifted off in the process of the second Gripper bar 25 moves along. It can be seen from FIG. 2 that in the position shown, the second gripper bar 25 over the first Gripper bar 15 can be moved away.
  • the first gripper bar 15 is also for height adjustment set up by the first gripper bar 15 and its first Holding tower 17 opposite on the outermost rail 22 in turn a second holding tower 21 is also assigned to which the first Gripper bar 15 can be docked by moving one out of the first gripper bar 15 extendable, not shown extension piece 23 on the second holding tower 21 is dockable.
