Definitions

  • From DE-U-298 10 785 is a cutting device of the generic type kind known whose knife holder with a knife bar guided adapter slide is releasably connected.
  • the Connection is made via a knife holder pin with wedge surfaces directed against the cutter bar, which is inserted into a recess on the adapter slide.
  • the adapter slide is perpendicular to the alignment of the pin a locking screw is arranged, the tip of which on the wedge surface of the pin acts and the knife holder without play clamped with the adapter slide. That through the cutting force effective tilting moment is due to an additional Support pin added.
  • This object is inventively for a device for Longitudinal cutting of material webs, one with a cutter bar connectable knife holder, which essentially of a carrier body and one opposite the carrier body adjustable in vertical and horizontal direction, with a circular knife provided cutter head, and the a plug connection with a lock for connection of the carrier body with the cutter head and / or the cutter bar has, the direction of insertion in the plane of the circular knife runs with the in the characterizing part of claim 1 specified means solved.
  • the solution according to the invention is also for a device for Longitudinal sections of material webs can be used where the knife holder not directly with the cutter bar but with an adapter slide that can be moved and locked on the cutter bar are connected.
  • a facility can then in addition or instead of the plug connection between Cutter head and carrier body a corresponding plug connection provided between the carrier body and the adapter slide his.
  • the Locking the plug connection of the knife holder as a whole removed from the adapter slide and against one new knife holder replaced without the positioning positioning of the adapter slide to the neighboring knife holders is changed.
  • Such Measure is required, for example, if the usually pneumatic actuator in the carrier body for the vertical movement of the cutter head, for example due to leaks in the piston-cylinder system, no more works properly or not at all.
  • the locking by a pin and the Recording bracing screw is formed.
  • Such a lock is easy to manufacture because of The pin has to be provided with an axial threaded hole, then there is also the advantage that the Locking is also accessible in the direction of insertion.
  • the Screw can be used here, for example, as an Allen screw be designed so that with an appropriate screwdriver the lock is easy to operate.
  • a cutter bar 1 is one Device for slitting material webs shown, attached to the four knife holders 2.1, 2.2, 2.3 and 2.4 are.
  • the knife holders 2 each have a carrier body 3 on which can be raised and lowered in the vertical direction a cutter head 4 fastened with a freely rotatable circular knife 5 which can also be raised horizontally.
  • the cutter head 4 of one Hand protection covers so that only the lower cutting area of the circular knife 5 is visible.
  • the circular knife 5 works after the horizontal adjustment against cutting rings 6, the attached to a knife shaft 7 at a distance from each other are.
  • the individual knife holder 2 can now on the knife bar 1 in horizontally shifted against each other and in definable Distances to each other can be fixed. To do this, click on the cutter bar 1 four parallel and at a distance from each other arranged guide rails 8.1, 8.2, 8.3 and 8.4 are provided, on which the carrier body 3 of the knife holder 2 each over an adapter slide 10 (Fig. 2) can be moved and fixed are stored.
  • Each adapter slide 10 is with a guide carriage 9.1 and 9.2 provided in such a way that the adapter slide 10 adjacent knife holder, for example the knife holder 2.1 alternately on an upper pair of guide rails 8.1 and 8.3 and the adapter slide 10 of the Knife holder 2.2 on a lower pair of guide strips 8.2 and 8.4.
  • both knife holders close together to position, since the adapter slide 10 each with their ends projecting beyond the width of the carrier body 3 Guide carriage 9 the carrier body 3 of the adjacent knife holder 2 can "drive under".
  • Carrier body 3 of a knife holder 2 with the relevant here Connections with the cutter head 4 on the one hand and an adapter slide 10 shown on the other hand.
  • the carrier body 3 is provided with an adjusting element 11, which is guided vertically in the carrier body 3 and with one here Known pneumatic actuator not shown Design for the downward movement and a return spring for the upward movement after the actuator has been depressurized connected is.
  • the cutter head 4 is connected to the adjusting element 11 via a a locking connector 12 connected.
  • the plug connection 12 is in the shown here Embodiment from a pin 13 with a cylindrical Cross section that in a corresponding hole on Adjusting element 11 inserted and on a bolt 14 on Control element 11 is fixed.
  • the cutter head 4 has an attachment which acts as a receptacle 15 serves for the free end of the pin 13, and the one corresponding fitting bore 16 is provided.
  • the pin 13 is somewhat shorter in its free length than the length of the Fitting bore 16 and provided with an axial threaded bore 17.
  • a hexagon socket screw can be used as a lock in the threaded bore 17 18 are screwed through which the Cutter head 4 with its receptacle 15 against the plug pin 13 can be clamped in the axial direction.
  • a cutter head 4 To replace a cutter head 4 is the lock serving screw 18 loosened. Even if the individual knife holder 2 lie close together, as shown in Fig. 1, can a cutter head 4 forward in the direction of arrow 21 to be pulled. To simplify access here, is on the forward-facing end face 22 of the cutter head 4 a undercut recess 23 is provided, in which a hook-shaped Trigger tool can be inserted.
  • a knife holder 2 designed in this way can now be used in a conventional manner Via a prismatic clamping rail on the cutter bar 1 on the one hand and a corresponding clamping part on the carrier body 3 releasably connected to the cutter bar 1.
  • the carrier body 3 is with a corresponding receptacle 15.1 provided, which in turn has a fitting bore 16.1, so that the carrier body 3 on the free end of the pin 13.1 can be plugged on.
  • a screw 18.1 screwed into an internal thread 17.1 is used again as a lock.
  • the form-fitting surfaces are again provided by a cylindrical cross bolt 19.2 which the recording 15.1 with a cylindrical surface 19.3 in Form fit is present.
  • Fig. 3 is another embodiment for the attachment of the plug pin, for example on the actuating element 11.
  • a pin 13 is used at both ends with an axial internal thread 17 and 26 is provided.
  • the pin is also in the middle provided with a cross pin 19.
  • the pin 13 is in a corresponding fitting hole 25 is inserted in the control element 11 and a fastening screw 27 firmly with the Adjusting element 11 braced against the cross pin 19, wherein here also corresponding semi-cylindrical contact surfaces on Control element 11 are provided.
  • the cutter head 4 (here only indicated), then - as described with reference to FIG. 2 - plugged onto the free end of the pin 13 and in the braced in the manner described above.
  • the execution allows it also to remove the cutter head 4 if instead of the screw 18 the fastening screw 27 is loosened. So it's an entrance given by both sides.
