Definitions

  • the invention relates to a cutting device for a flat material web, in particular for the production of labels, with a housing and a fastening device for coupling the housing to a printing unit, the fastening device having a holding section that can be inserted into a complementarily designed receptacle and can be mounted there in a stationary manner.
  • the cutting device is connected to a printing unit in a separable manner via a fastening element.
  • a precise definition of the position of the cutting section in relation to the print head of the printing unit is just as impossible as changing the distance of the cutting section to Print head of the printing unit.
  • the present invention is therefore based on the object to counter the disadvantages of the known cutting device described above.
  • a cutting device of the type mentioned at the outset which is characterized in that the housing of the cutting device is adjustable with respect to the holding section.
  • the holding section of the fastening device which may be formed by an anchor plate, for example, is first inserted and fixed in the receptacle on the printing unit.
  • the housing containing or carrying the cutting unit is adjustable relative to the holding section, so that the distance between the housing and thus the cutting unit from the holding section can be adjusted.
  • the fastening device could be L-shaped, the housing being carried by an approximately horizontal leg of the L-shape and being displaceable thereon.
  • the holding section on its side facing the housing has at least one rod, sleeve or pin-like receiving area projecting in the direction of the housing, which extends through the housing.
  • the housing can be slidably held and / or guided by the projecting receiving area.
  • this works through Free end of the projecting receiving area which extends through the housing together with an adjusting device.
  • the adjusting device has a reference element connected to the free end of the projecting receiving area, the distance of the reference element from the housing and thus the distance of the housing from the holding section being adjustable.
  • the reference element is a plate which is connected to the free ends of two projecting receiving areas and has an adjusting screw. It would be conceivable that the set screw is screwed into a thread in the plate and is supported on the housing. However, an embodiment is preferred in which the set screw or a threaded spindle is screwed into the housing in an adjustable manner and is rotatable relative to the reference element but not axially displaceable. The housing is then moved towards or away from the reference element by turning the set screw or the threaded spindle.
  • the figures show a cutting device according to a preferred embodiment of the invention.
  • the cutting device comprises a housing 2, on which a cutting unit 6, which can be covered with a pivotable housing cover 4, is placed.
  • the electronics and the drive for the cutting unit 6 are accommodated in the housing 2.
  • the cutting device is arranged with its housing 2 via a fastening device 8 on a printer unit 10 which is only partially shown.
  • the cutting device comprises an input section 12 for a flat material web to be separated into successive sections, a cutting section 14 and an output section 16 for sections of the web cut transversely to the transport direction.
  • the cutting unit 6 comprises a cutting roller 18 which can be rotated transversely to the transport direction of the flat material web to be cut and also carries knife bars 20 which run transversely to the transport direction.
  • the cutting roller 18 is driven in a solenoid-controlled manner during the cutting process, so that the knife bars rotate past a stationary, prestressed cutting bar 22 which serves as a counter bearing for the knife bars 20. Since the knife strips 20, as can be seen from FIG. 1, run slightly spiral, the intersection, i.e. the point of contact of the knife bar 20 and cutting bar 22, transverse to the direction of transport from one longitudinal edge of the flat material web to the other.
  • the damping device 24 comprises a curved damping plate 26, which is assigned to a guide surface 28 of the input section 12.
  • the damping plate 26 and the guide surface 28 delimit an insertion slot 30 tapering in the transport direction for the flat material web to be cut into sections.
  • the damping plate 26 is articulated on the fastening device 8 so as to be pivotable about an axis 31 running transversely to the transport direction and is prestressed in the direction of the guide surface 28 by a spiral spring 32.
  • Various holding points 34 are provided for the leg 36 of the spiral spring 32 facing away from the damping plate 26, by means of which the pretensioning force of the damping device 24 can be adjusted.
  • the damping plate 26 is supported against the guide surface 28, the guide plate 26 not resting on the guide surface 28 with an edge running transversely to the transport direction, but touching the guide surface 28 via lateral spacers 38, so that there is a slot-shaped spacing, by which also thin guideways, such as thermal printing paper with a thickness of about 0.18 mm can be introduced in the direction of the cutting unit 6.
  • shock waves now occur during operation of the cutting device these lead to the deflection of the resiliently preloaded damping plate 26, so that so much energy is extracted from the shock waves by suitable choice of the preload that they cannot have a disruptive effect in the area of the print head of the printing unit 10.
  • the fastening device 8 comprises a holding section, designated overall by reference numeral 40, which has on its side facing away from the housing 2 an anchor plate 42 which can be inserted into a complementarily designed receptacle 44 of the printing unit 10.
  • the anchor plate 42 comprises two threaded bolts 46 which pass through an opening 48 of the holding section 40 in the direction of the housing 2 and are screwed to a nut 50 at their free end. By tightening the nut 50, the holding section 40 can be fixed in place on the printing unit 10; only then is the housing 2 assembled with the cutting unit 6.
  • the holding section 40 furthermore has two parallel bolts 52 which project in the direction of the housing 2 and which are fastened to the holding section 40 via threaded bores 54 and screws 56 on the end face.
  • the bolts 52 hold and guide the housing 2.
  • through openings 60 are provided in the housing 2, through which the bolts 52 extend when the housing 2 is pushed onto them.
  • the free ends 62 of the bolts 52 which pass through the housing are connected to a plate-shaped reference element 68 via threaded bores 64 and screws 66 on the end face.
  • the housing 2 is displaceably mounted on the bolt 52, the reference element 68 on the one hand and a sleeve 72 forming an axial stop 70 on the other hand, which is pushed onto a bolt 52 and arranged between the housing 2 and the holding section 40, forming a limitation.
  • a set screw 74 is provided which extends from the outside through a non-threaded through opening 76 in the reference element 68 and is screwed into an externally threaded section 78 within the housing 2.
  • the set screw 74 is rotatable with respect to the unthreaded through opening 76 in the reference element 68, and it is coupled in the axial direction to the reference element by means of an annular disk and a toothed spring washer such that when the set screw 74 is screwed in or unscrewed into or out of the threaded section 78, the housing 2 is moved in the direction of the reference element 68 or away from it in the direction of the stop 70 of the sleeve 72. In this way, a fine adjustment of the distance of the cutting section 14 from the print head of the printing unit 10 can be achieved.
  • the housing 2 is guided essentially free of play on the bolt 52 and is adjustable by the adjusting device 80 formed by reference element 68, adjusting screw 74 and internal thread section 78.
