Definitions

  • the invention relates to a cutting device which is guided only in the direction of the cutting edge of a cutting bar for a material web which can be transported in steps and has a cutting wheel which can be moved back and forth along a cutting bar and which can optionally be set in the cutting position in at least one direction of movement, rotatably arranged on a carriage on an axis and one on arranged on the same axis, running on the material web to be cut.
  • a cutting device which is guided only in the direction of the cutting edge of a cutting bar for a material web which can be transported in steps and has a cutting wheel which can be moved back and forth along a cutting bar and which can optionally be set in the cutting position in at least one direction of movement, rotatably arranged on a carriage on an axis and one on arranged on the same axis, running on the material web to be cut.
  • Such cutting devices are known in data processing systems, in particular in printers.
  • a cutting device with a reciprocating cutting wheel which, when in contact with a cutting edge, cuts off the form or the like which is pushed through a slot on the cutting edge of the cutting bar itself. There is no provision for restraint here.
  • a cutting device for sheet material is provided, which can be cut off both stationary and with a continuous feed.
  • the ring-shaped cutting knife is connected to the knife carriage via a swivel plate in such a way that an actuating cable attached to the swivel plate and causing the displacement of the carriage presses the cutting knife against the cutting bar when moving in one direction, while the swivel plate presses against it when the movement is reversed abuts a projection of the carriage so that the cutting knife is raised above the cutting bar, wherein the annular cutting knife can be lifted against the force of a spring from the cutting bar in the end position.
  • the hold-down is achieved by a spherically shaped hub, which on the one hand carries the cutting knife itself and on the other hand rolls on the paper web to be cut during the reciprocating movement of the cutting wheel.
  • this type of hold-down has the very decisive disadvantage that the material to be cut is warped, so that there is no clean cutting edge.
  • the object on which the invention is based is to provide, in such a cutting device, a hold-down which, in the parts of a material web, preferably a paper web, to be cut provides a flawless cutting edge which also has no warping and no crowning at the outer ends of the cutting edge.
  • the roller in the cutting position serves as the drive roller for the cutting wheel and rolls on the material web lying on the cutting bar, in addition that the common axis carrying the drive roller and the cutting wheel is about 3 ° to about 5 ° in the direction of the Material web extending cutting edge normals is aligned obliquely and that the diameter of the cutting wheel driven by the drive roller is noticeably larger than the diameter of the drive roller.
  • the arrangement is such that the outer surface of the drive roller is a cylinder jacket surface, and that the angle formed by the cutting roller and the drive roller supporting shaft with the cutting edge normal is about 3.5 0th It is particularly advantageous that the peripheral speed of the edge of the cutting wheel is about 15% to 17% higher than the peripheral speed of the circumferential surface of the drive roller during the cutting process.
  • this new cutting device for example for a printer for bank statements or the like, it is of particular importance if the cutting device itself is accommodated on the carriage carrying the print head and, in the process, provides devices by means of which the cutting roller on one line after the printing process has ended or transferred to work position on several lines and can be returned to the rest position at the end of the cutting process.
  • the arrangement is preferably such that the cutting wheel can be moved into the cutting position when one ramp is passed and the cutting wheel can be moved into the rest position when the other ramp is passed such that the latching claw under the action of the latching claw spring moves downward through the action of the other ramp shifted locking lug of the locking tab engages and sets this.
  • a part of a cutting device 1 which carries a cutting wheel 4 on a support arm 2 on an axis 3, which has a circular cutting edge 5. The is guided along a cutting edge 6 during the cutting process along a cutting edge 6.
  • a drive roller 8 is arranged, which has a drive cylinder 9.
  • the cutting bar has a ramp 10 which is only schematically indicated in FIG. 1 and also a ramp 11 which can only be seen in FIG. 4B.
  • the cutting bar 7 is, as indicated schematically in FIG. 1, attached to a frame 12.
  • the axis 3 carrying the cutting wheel 4 and the drive roller 8 with the drive cylinder 9 is to be cut off at an angle between approximately 3 ° and approximately 5 °, preferably at an angle of approximately 3.5 °, against the transport direction Material web or arranged against the cutting bar normal.
  • the support arm 2 is somewhat angled at its upper end. However, this is only important in connection with the position of the cutting bar and its cutting edge, but is not absolutely necessary.
  • the switchover device for the cutting wheel which causes a switchover from the rest position to the cutting position, will be explained in detail.
  • the z. B. a print head and the cutter carrying carriage 33, of which only a base plate of the cutter 32 is shown here, with the cutter in the rest position back and forth and causes z. B. a line-by-line printing, for example a record carrier, e.g. B. a paper web.
  • the cutting device can also be used as such without a print head.
  • a catch arm 13 is attached to the frame 12 and can be pivoted upwards about a joint.
  • This catch arm 13 carries a catch claw 14 and is held in its latched position by a spring 15 which is suspended between two pins 16.
  • a locking tab 17 is articulated on the carriage 33, which is also held in its rest position by a spring 18 which is suspended on pins 19 and 20.
  • This locking tab 17 has a locking claw 21 and a release claw 22.
  • the support arm 2 has two slots 23 and can therefore in the longitudinal direction, ie. H. in the drawing from bottom to top and from top to bottom, guided by guide bolts 23a for the support arm 2 to slide.
  • the support arm 2 also has a locking lug 24, in which the locking claw 21 of the locking tab 17, which is normally under spring tension, engages in the idle state and thus holds the support arm 2 in its lower position.
  • the carriage drive is reversed such that the carriage 33 is now guided all the way to the left.
  • the mode of operation of the ramp 10 should initially only be taken into account in part.
  • the release claw 22 moves under the catch claw 14 of the catch arm 13 against the bias of the spring 15.
  • the catch arm 13 can be rotated about the pivot point (not shown). If now the movement of the carriage starts in the opposite direction, then the release claw 22 remains on the catch claw 14 and causes it so that the locking claw 21 releases the locking lug 24 after a short distance.
  • the support arm with the cutting wheel thereon with the drive roller and drive cylinder can now move upwards.
  • the locking tab 17 is still held by the catch arm 13 and undergoes a rotational movement until the catch claw 14 and the release claw 22 slide against one another.
  • the rotational movement of the locking tab now reverses, and the locking claw 21 hits the support arm 2 with a delay, which has now followed the ramp 10, that is to say has made an upward movement, so that the locking claw 21 can no longer lock in the locking lug 24.
  • the cutting wheel now continues to follow the ramp contour and goes completely into the cutting position at the level of the cutting bar 6.
  • the force with which the spring 25 presses the drive cylinder against the material web lying on the cutting bar is also decisive for the size of the angle that the axis 3 forms with the cutting edge normal.
  • a tensile force of 8 Newtons has proven to be particularly favorable for an angle of 3.5 °.
  • ramps 10 and 11 are designed as guide rails 29 and 30, the guide rail 29 being cranked away from the cutting bar, while the guide rail 30 is at a uniform distance from the cutting bar 7.
  • the cutting wheel carries a guide collar 28 at its rear end and that the cutting wheel 4 with the drive roller 8 and drive cylinder 9 can be moved along the axis 3 under spring tension.
  • the cutting device mounted on a carriage according to the invention does not require holding down the material web to be cut, because the inclined position of the axis 3 carrying the cutting wheel with drive roller and drive cylinder also exerts a force component acting in the transport direction of the material web on the material web to be trimmed via the drive cylinder 9, because furthermore by the smaller diameter of the drive cylinder compared to the diameter of the circular Cutting edge 5 of the cutting wheel 4, the peripheral speed of the cutting edge is considerably greater than the peripheral speed of the drive cylinder 9, which in turn results in the particular force acting on the surface of the material web to be cut, while at the same time the actual circular cutting edge of the cutting wheel always leads the contact surface of the drive cylinder 9.
