Definitions

  • the invention relates to a longitudinal cutting device for a moving fibrous web with a zugstoffunternosen positioning for at least one cutting device, preferably a cutting blade or a high-pressure water jet cutting head.
  • a positioning cylinder arranged laterally next to the paper or board machine is used for this purpose. This is defined by its stops in the cutting position and only needs to be acted upon with air pressure in two directions.
  • the stroke of the cylinder must already be very large, resulting in an undesirable wide reaching the cylinder into the maintenance room next to the paper or board machine.
  • a positioning motor is used, for example with a belt drive for the cutting device, a relatively large control effort is again required.
  • the invention is therefore an object of the invention to provide a slitter for a running fibrous web, which is easy to control and takes up little space laterally next to the current fibrous web.
  • the longitudinal cutting device of the invention solves this problem by the traction-assisted positioning device for realizing at least one direction of movement of the cutting device at least has a fixed and at least one loose pulley for the traction means.
  • a bottle-pull-like device which allows a large translation.
  • the power transmission but the Wegüber GmbH.
  • a short drive unit travel allows the cutter to move to the desired cutting or parking position. The entire device builds the side of the paper web very small, even if the path of the cutting element is large.
  • a short stroke of the traction means causes a relatively long travel of the cutter.
  • ropes flat and V-belts and in particular toothed belts are suitable because of a slip-free power transmission.
  • the traction means are generally not usable as a pressure medium, it is advantageous if the zugstoffuntersectione positioning for the realization of two directions of movement of the cutting device each has at least one fixed and at least one loose pulley for the traction means. Since these two units are arranged parallel to each other with at least one fixed and one loose pulley, they take up no additional space Claim. Alternatively, it is also conceivable to realize one of the directions of movement via a spring element.
  • the traction-assisted positioning device has at least one linear drive.
  • these linear actuators in turn, one is preferably selected, which is formed by a cylinder-piston unit.
  • the direction of movement of the linear drive can be arranged to save space parallel to the direction of movement of the cutting element.
  • the longitudinal cutting device is particularly small if the linear drive is actually arranged parallel to the travel path of the cutting element.
  • the linear drive is designed so that it acts on a holder on which at least one loose pulley for the traction means is mounted. In this way, the travel of the drive acts exactly on the loose pulley around which the traction device is looped.
  • a Switzerlandstoffende which is either the same or another traction means (as in a power pulley or differential pulley)
  • there is a translation with respect to the path which is there four times or even greater.
  • a guide for the cutting device or for a carriage carrying this cutting device is provided on a traverse.
  • the guide ensures that the distance to the moving fibrous web is ensured during the process.
  • the traverse is designed as a box. In this way it is prevented that dust or dirt can reach the guide, and the cutting head is largely protected from tearing fibrous webs.
  • the linear drive is integrated in the box.
  • the entire longitudinal cutting device then forms a largely (apart from the passage of the cutting element) closed and compact unit. It can be quickly mounted as a unit at any point on the paper or board machine.
  • a complete unit can be exchanged quickly so that there is no loss of production in the paper or board machine.
  • Fig. 1 shows the longitudinal cutting device 1 according to the invention in cross section.
  • the longitudinal cutting device 1 is provided with a cutting device 2, which is formed in this embodiment substantially by a high-pressure water jet nozzle 3.
  • the water jet emerging from this high-pressure water jet nozzle 3 is capable of cutting a continuous fibrous web, not shown, preferably a paper or board web.
  • an optionally rotating knife or any other form of cutting device can also be used here.
  • the cutter 2 is connected to a carriage 5 via a cutter holder 4.
  • the carriage 5 is (in FIG. 1 in the leaf level) in a guide 7 movable.
  • rollers 6, which run in rails 7a.
  • These rails 7a are attached to a crossbar 8, which is advantageously designed in the form of an almost closed box 9. As a result, the guide 7 is largely protected against dust deposits.
  • the drive for the carriage 5 is a linear drive 10, in particular a cylinder-piston unit 10 a, which is connected via a holder 11 with the cross member 8. Also, it is protected within the box 9 housed.
  • the cylinder-piston unit 10a exerts a force on Pulling 12 off, which in turn attacks the car.
  • the traction device wraps around at least a fixed deflection roller 13 and a loose deflection roller 14. In the concrete case, the traction means is thus connected as a pulley, in particular as a power pulley or a differential pulley.
  • FIGS. 2 to 4 The positioning 18 of the cutting device 2 and its operation are in the FIGS. 2 to 4 clarified. For clarity, the cutting device 2 itself and the traverse 8 are not shown in the drawing.
  • FIG. 2 shows the carriage 5 for the cutting device 2 in a first cutting position A and
  • FIG. 4 shows the car in its parking position P. Because the cylinder-piston unit 10a in the exemplary embodiment has three positions, there is an additional second cutting position B, which in FIG. 3 is shown.
  • v is called the direction of movement to the first cutting position A and r is the direction of movement to the parking position P.
  • two traction means 12 are provided, the analog 12V, 12v 'and 12r, 12r' bear analogously to the pulleys 13,.
  • the piston 17 of the cylinder-piston unit 10a engages via a connection plate 16 directly to two loose pulleys 15v, 15r attached thereto.
  • one of the traction means 12v 'or 12r' is loaded to train.
  • the distance between the loose pulleys 14v and 14r or 15v and 15r which varies with a Wegüber acidsdorf of 4: 1 moves the carriage, which is connected to the second traction means 12v, 12r, which wraps around the respective second loose pulley 14v, 14r.
  • Longitudinal cutting device 1 together with the positioning device 18 is extremely compact and can be easily accommodated in the available space without standing out too far to the side of the paper or board machine. Apart from a compressed air supply via the compressed air connections 19 which can be switched on and off, there is no need to make any effort to control the cutting device 2 at the desired location.
