Definitions

  • the invention relates to a knife roller with at least one foil knife, which can be fastened to a multi-part roller body which has suction openings on its circumference and suction channels connected to them and running in the longitudinal direction.
  • a knife roller of the type mentioned is e.g. known from U.S. Patent 4,537,588. It is used in the production of window envelopes to cut out the window. While the envelope blank is being transported from the knife roller to another processing station, the knife roller must first hold the piece of waste created by the window cutout for a certain time and then discharge it into a suction funnel. For this purpose, the knife roller has suction openings which can be subjected to a vacuum via a suction channel.
  • the invention has for its object a knife roller to design for envelope production and other applications in such a way that it is as versatile as possible and, above all, able to safely and reliably dispose of more than just a single piece of waste.
  • the invention provides that suction openings are provided in several rows of suction holes and offset in the circumferential direction, that one suction channel is assigned to each row of suction holes and that at least one suction air control channel and at least one adjustable suction air control disk are provided, with the aid of which the suction air control channel can optionally be used with the various suction channels, rows of suction holes and their suction openings can be connected.
  • the said measures allow, e.g. When using twelve rows of suction holes and a corresponding number of suction channels, three suction air control channels and two suction air control disks on the front, three different waste pieces can be safely and reliably disposed of, which are distributed over the circumference of the knife roller and have to be transported away and dispensed at the right moment. It is furthermore advantageous that with the aid of suction openings in the film knife (s) only the required suction openings of the various rows of suction holes are subjected to vacuum, while the other suction openings are covered.
  • Suction control in the form described can be carried out regardless of whether the foil knives are held on the multi-part roller body with the aid of magnetic strips or with the aid of a mechanical tensioning and fastening device.
  • a cutting station 1 for window envelopes comprises a knife roller 2 and a rotating counter roller 3 serving as a counter tool, between which a paper web 4 which has not yet been divided into envelope blanks is passed and processed.
  • the counter roller 3 is mounted in a carrier 5 and, together with this, can also be moved in the direction of the arrows towards the knife roller 2 and away from it.
  • the cutting station 1a according to FIG. 2 is used for processing envelope blanks 4a, a cutting bar 3a being provided as a counter-tool for the knife roller 2.
  • the cutting bar 3a can be adjusted together with its carrier 5 in the direction of the arrows towards the knife roller 2 and away from it.
  • the knife roller 2 has a suction bar 6 (FIG. 3) with suction openings 7, the suction bar 6 being angularly arranged in its phase position relative to the feed and discharge roller 8, 9.
  • the envelope blank 4a gripped by the suction bar 6 is passed along a circular path under the counter tool or the cutting bar 3a, a window being cut out.
  • the window cutout or the waste piece is held within the window knife periphery by means of suction and finally discharged into a suction funnel 10, while the envelope blank 4a is transported further by the discharging roller 9.
  • FIG 3 shows the knife roller 2 and its storage as well as essential parts of the knife roller 2 in section, but without the foil knives and without the parts used for fastening and tensioning the foil knives.
  • the knife roller 2 comprises a carrier shaft 11, which is supported by means of several ball bearings 12 in a machine frame 13 and can be driven by means of a toothed wheel 14.
  • the parts (not shown in FIG. 3) for fastening and tensioning the film knives can be fastened on the carrier shaft 11, while the other end 16 of the carrier shaft 11 carries control disks 17, 18 and 19 for the suction air control, which at one time stationary suction air control valve 20 belong.
  • the suction air control valve 20 and its three control disks 17, 18 and 19 three longitudinal bores 21, 22 and 23 located in the carrier shaft 11 are acted upon by vacuum from a vacuum line 24 in accordance with the angular position of the carrier shaft 11.
  • suction air control valves 20 are basically known.
  • the carrier shaft 11 carries a left receiving disk 25 and a right receiving disk 26 for the suction bar 6, with the aid of which an envelope blank 4a is gripped by means of suction and transported further.
  • the suction bar 6 has a suction channel 27 below the suction openings 7, the suction air supply of which is by means of a second suction air control valve 28 and a separately adjustable suction air control disk 29.
  • the suction air control valve 28 there is a suction air control channel 30 or 31, which is connected to one another according to FIG. 3, as is in the receiving disk 26 arranged on the right for the suction bar 6, which are connected to one another according to FIG.
  • the three longitudinal bores 21, 22 and 23 in the carrier shaft 11 open at the shaft end 15 in transverse bores 33, 34 and 35, as can also be seen in FIG. 3.
  • the position and arrangement of the longitudinal bores 21 to 23 and the transverse bores 33 to 35 can also be seen from FIGS. 4 and 5.
  • FIGS. 9 and 10 On the right shaft end 15 of the carrier shaft 11 there is also a holding and sapnn device 39 with magnetic strips 40 according to FIGS. 9 and 10, used for fastening and tensioning foil knives 36, 37 and 38, or a mechanically acting holding and tensioning device 41 according to FIGS. 12 to 14.
  • These holding devices 39 and 41 are only shown in Figures 9 and 10 or 12 to 14 and not in Fig. 3 for clarity.
  • FIG. 6 shows in section parts of the holding and tensioning device for the foil knives, the features shown being the same both in the holding and tensioning device 39 with magnetic strips 40 and in the mechanical holding and tensioning device 41.
  • both holding and tensioning devices include an approximately semi-cylindrical shell 42, which offset suction openings 43 along a plurality of rows of suction holes in the circumferential direction 44 or along twelve rows of suction holes a to 1 (Fig. 11).
  • the shell 42 forms, at least in part, the effective roller surface 45, from which the suction openings 43 extend radially inward to the suction channels 46, which are arranged directly below the roller surface 45.
  • each suction hole row 44 or suction hole row a to 1 is assigned a suction channel 46, and all suction hole rows 44 and suction channels 46 extend parallel to one another and in the longitudinal direction of the roll.
  • the semi-cylindrical shell 42 On its inside 47, the semi-cylindrical shell 42 has three suction air control channels 48, 49 and 50 in the form of channel-shaped recesses. In the assembled state, these suction air control channels 48, 49 and 50 are each assigned to one of the three transverse bores 33, 34 and 35 in the carrier shaft 11.
  • the first suction air control duct 48 is - as is also apparent from FIG. 6 - connected to the first suction hole row a by means of transverse bores 51.
  • the second suction air control channel 49 also extends parallel to the suction channels 44 over a little more than half the shell length and ends at one end 52 of a control window 53. Basically the same applies to the third suction air control channel 50, which, however, on the other end 54 of the shell 42 ends at a control window 55.
  • suction air control disks 56 and 57 On both ends 52 and 54 there are also suction air control disks 56 and 57, each with a control channel 58 and 59, from each of which a control window 60 directed radially outward branches off.
  • the suction air control channels 49, 50 with the suction channels 46 are respective Suction hole rows 44 optionally connectable by adjusting the suction air control disks 56, 57.
  • clamping screws 61 the suction air control disks 56, 57 are fixed on the carrier shaft 11 and locking screws 62 are provided in order to close the suction channels 46 at their front ends.
  • the two suction air control disks 56, 57 are basically of the same design and are divided into two for assembly reasons, as can also be seen from FIGS. 7 and 8. Your two halves 63, 64 are held together with the aid of clamping screws 65. Both suction air control disks 56 and 57 are also ring-shaped, as can be seen from FIGS. 6 to 8.
  • the approximately semi-cylindrical shell 42 not only partially forms the roller surface 45, but also serves as a carrier for the foil knives 36, 37 and 38.
  • magnetic strips 40 are provided. They are parallel to the longitudinal axis of the roll and between the rows of suction holes a to 1. Magnetic strips 4o are also provided in sufficient numbers outside the row of suction holes 44 to give the foil knives 36 to 38 a secure hold.
  • the suction air control channel 48 is arranged approximately centrally in the shell 42, while the second suction air control channel 49 is offset more to the left and the third suction air control channel 50 is shifted more to the right. Furthermore, the second suction air control channel 49 is open to the left end face 52, while the third suction air control channel 50 is open to the right end face 54 is open.
  • a semi-cylindrical adapter 67 is also used to fasten the semi-cylindrical shell 42 to the carrier shaft 11, as can be seen from FIGS. 9 and 10.
