Definitions

  • the invention relates to a cutting device for a conveyed flat material web, in particular for producing labels, the cutting device having an input section, a cutting section, an output section, and a damping device assigned to the input section and facing the flat material web.
  • DE-OS 2 364 035 discloses a generic device for severing web-like material, in particular paper webs for the production of cards. Before the material web reaches a cutting device with which it is cut into individual sections, it is passed between a brake roller and an angled plate or a trough in order to relieve the web of part of the tension which is created by an upstream transport device and so that Prevent the formation of burrs or other deformations on perforation holes of the material web that interact with the transport device.
  • a cutting mechanism is used to cut off sections of a web of a recording medium, which then serve, for example, as tags.
  • the cutting mechanism cuts the longitudinally moving web transversely and has interacting ones Cutting knife.
  • the cutting mechanism is arranged within a housing with an input section in the form of an opening for inserting the web. The separated sections of the web are then fed to a stacking device arranged within the housing.
  • Such cutting devices are arranged downstream of a printing unit, for example as a so-called label cutter, in which the continuously conveyed flat material web is printed in sections.
  • a printing unit for example as a so-called label cutter, in which the continuously conveyed flat material web is printed in sections.
  • successive printed sections of the flat material web are cut off essentially transversely to the web direction.
  • the separating cut running transversely to the transport direction is usually carried out by a rotating knife roller, the axis of rotation of which runs perpendicular to the transport direction and parallel to the plane of the web.
  • At least one knife bar provided on the circumference of the cutting roller preferably runs slightly spiral, so that a cut running from one side of the web to the other side is produced when the cutting device is in operation.
  • the cutting speed is very high compared to the transport speed of the flat material web
  • the cut running perpendicular to the transport direction disrupts or blocks the web transport process. It was found that shock waves propagating against the direction of transport are formed in the flat material web. In addition, twists occur in the plane of the flat material web around the current position of the intersection running transverse to the web.
  • twists therefore result in the fact that - when considering a cutting process - in the area behind the intersection of the knife bar, ie where it has already been separated, that which is subsequently conveyed No resistance is opposed to the path, but a maximum resistance is opposed at the current position of the intersection of the path being fed. At the section that has not yet been separated in the cutting direction before the current position of the intersection, the path conveyed is opposed to a resistance which is of the order of magnitude between the resistance values for the two sections described above.
  • shock waves propagate against the transport direction of the flat material web and can cause the print head of an upstream printing unit to lift off, which leads to poor print quality. With bar code printers, this can make the printed bar code illegible.
  • the brake roller from DE-OS 2 364 035 is relatively complex and expensive and lies only on its surface line on the flat material web, so that no flat contact and no sufficient damping of the shock waves can occur.
  • the present invention is therefore based on the object of developing a cutting device of the generic type in such a way that the unwanted shock waves resulting from the cutting process are absorbed and damped in such a way that they can only have a significantly reduced adverse influence on a device connected upstream of the input cutout.
  • a cutting device of the type mentioned which is characterized in that the damping device for receiving and damping as a result of Cutting process occurring shock waves in the flat material web is formed by a damping plate or a damping plate.
  • the occurrence of shock waves per se is not prevented, but rather their disruptive propagation against the direction of transport.
  • the damping device is formed by a damping plate or a damping plate, which faces the flat material web.
  • the damping plate or sheet could in itself rest on the flat material web and thus prevent the shock waves from spreading.
  • the damping device in particular the plate or sheet, is prestressed in the direction of the flat material web and the prestressing force of the damping device is adjustable. The latter can be done, for example, by different positioning or stopping points of a leg of a spring, in particular a spiral spring.
  • the damping device is designed and arranged such that it also serves as a guide for the flat material web.
  • the already mentioned curved design of the damping plate or plate has proven to be advantageous.
  • the input section of the cutting device preferably has an insertion slot which tapers in the transport direction and is delimited at least on one side by the damping plate or the sheet metal. This insertion slot is delimited on the side opposite the damping plate or sheet by a guide surface, which in particular is also curved in an arc. The two curvatures are advantageously in the same direction.
  • the damping device can advantageously be designed such that the damping plate or plate rests on the guide surface.
  • the plate or sheet can rest on the guide surface with a surface or edge running transversely to the transport direction.
  • an embodiment is preferred in which the damping plate or plate rests on the guide surface via lateral spacers, so that even a very thin web, such as thermal printing paper with a thickness of approximately 0.18 mm, can be easily inserted into the input section of the Cutting device can be introduced.
  • the clear cross-section of the insertion slot preferably has a smallest extension transversely to the plane of the web, which is slightly larger than the thickness of the web. Even minor shock wave amplitudes are then effectively damped.
  • the damping plate or sheet has a smallest distance from the guide surface of 0.35 to 2 mm, preferably 0.5 to 1 mm.
  • 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 point of intersection, ie the point of contact between the knife strip 20 and the cutting bar 22, moves transversely to the transport direction 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 rather 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 prestressed damping plate 26, so that as much energy is removed from the shock waves by a suitable choice of the prestress 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, with on the one hand the reference element 68 and on the other hand a sleeve 72 forming an axial stop 70, which is pushed onto a bolt 52 and between the housing 2 and the holding section 40 is arranged to form a boundary.
  • an adjusting 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 can be adjusted by the adjusting device 80 formed by reference element 68, adjusting screw 74 and internal thread section 78.
