Definitions

  • the present invention relates to a device for grooving cardboard blank according to the preamble of claim 1.
  • triangular grooves are cut in cardboard blank.
  • the opening angle, also referred to as the groove angle, between the two groove flanks is determined by the board thickness, the board material and, if applicable, the one or two-sided cover, and by the function of the cut groove on the box produced from the cardboard blank.
  • a generic cardboard groove machine is from the CN 101200091 B known.
  • the Nutenschneidwerkmaschinee are axially adjustable mounted on parallel to the transport drum support beams. They each have two at a fixed angle obliquely to each other attached to a blade holder knife. The change in the groove angle is effected by a time-consuming replacement of the respective blade receptacles against those with a different angular position of the knife. Due to the changed blade positions also arranged in each case before or after the Nutenschneidtechnikmaschineen arranged Poppenniederhalter and Spanabweiser.
  • the cardboard groove machine shown is the support beam with the Nutenschneidwerkmaschineen about an axially parallel axis in the region of the drum circumference pivotable.
  • the angle of the Nutenschneidtechnikmaschinee can be adjusted by a running approximately through the cutting tips of their knife pivot axis to the transport drum, which can be their common cutting angle or the resulting groove angle change together.
  • the adjustment effort for the Pappenniederhalter and Spanabweiser but remains and mutually independently set groove angles are not possible.
  • the object of the present invention is to provide a paperboard machine according to the preamble of claim 1, which allows an easy-to-use and separate adjustment of the Nutenschneidtechnikmaschinee and its periphery.
  • the respective desired groove angle can be set independently of each other on the Nutenschneidwerkmaschineen without replacing the knife holders.
  • the respective groove cutting tool does not have to be removed from the support beam for this purpose.
  • the adjustment of the groove angle is carried out within the respective groove cutting tool, so that the support beams are rigidly arranged in the frame and can be used for other work equipment, such as Pappenniederhalter, Spanabweiser and so on.
  • a pivot axis parallel to the drum rotation axis for the blade holder is defined by the sheet guide.
  • the respectively required groove angle can be adjusted quickly and reproducibly, if the blade holder and / or the bow guide have a scale with angle division, at which the resulting from certain angular positions of the knife holder groove angle can be read.
  • the sheet guide is designed as a running arc in the contact surface on which the blade holder can be fixed by clamping means. Cutting forces are safely absorbed by the sheet guide and transmitted to the support bar rigidly received in the frame.
  • the knife holder is designed as a removable part, worn knives can be replaced quickly and easily. Because a new knife set can be pre-assembled and aligned on a second knife holder. In addition, various, optionally usable knife shapes and arrangements can be kept ready.
  • the sheet guide is received in the groove cutting tool substantially radially adjustable to the transport drum. Associated settings and adjustments to the blade holder itself are not required.
  • the groove position can be corrected in the cardboard blank without the Nutenschneidwerkmaschine must be moved on the support beam.
  • the deflector is designed as a chip lifter to remove possibly adhering chips in the groove.
  • the deflecting plate merges into a discharge channel leading away substantially radially from the transport drum, through which the chips can be led out of the paperboard machine. With the advantage of a significantly reduced dust load, the discharge channel is connected to a disposal device for the chips.
  • the cardboard blank in the region of at least one knife against the drum shell holding down pressure element in particular the leading edge of the cardboard blank is pressed against the drum shell, whereby a widening to the card edge groove is avoided.
  • the pressing element holds down the cardboard blank upstream of the at least one knife in the region of the subsequently cut groove.
  • the pressure element is designed as a deflector, over which shavings arising during groove cutting are derived from the transport drum.
  • Fig. 1 1 schematically consists of a driven, horizontally mounted transport drum 11 and a plurality of endlessly circulating rollers 54 and spaced from each other, the transport drum 11 to form an inlet 14 and an outlet 15 partially wrapped belt 51 and between the belt 51 in one Defined distance from the drum shell arranged Nutenschneidtechnikmaschineen 72.
  • the inlet 14 supplied cardboard blanks 2 are conveyed by the belt 51 promoting effect on the drum shell and in the transport direction 11a in an approximately 180 ° rotation of the transport drum 11 from the bottom vertex of the transport drum 11 lying inlet 14 for lying in the upper vertex outlet 15 promoted and thereby past the Nutenschneidtechnikmaschineen 72, where with appropriately shaped slot knives 71 a chip 6 with, for example, substantially triangular cross-section of the paperboard cut 2 is cut out.
  • the feeder 101 in Fig. 1 has a paperboard magazine 102 containing a stack 4 of stacked cardboard blank.
  • the respective lowermost cardboard blank 2 is pushed out by a first board slider 104.1 under a front stop 103 and transferred to an intermediate position 105, from which the board blank 2 is fed to the inlet 14 with a second board slider 104.2 aligned with outer guide rails 106.
  • the board slides 104.1, 104.2 are coupled together at a fixed distance and are moved in a constant delivery stroke 107 equal to this distance clockwise back and forth.
  • the feeding speed is equal to the rotational speed of the transport drum 11 or is slightly above it, so that the cardboard blanks 2 quasi forcibly inserted into the inlet 14 between the transport drum 11 and belt 51.
  • the export 111 in Fig. 1 has an obliquely sloping forward delivery table 112 to which the expiring from the outlet 15, finished grooved cardboard cuttings 3 are dropped and stacked to stack 5. Due to the arrangement of the outlet 15 in the upper vertex of the transport drum 11, the cut grooves 3a in the leaking cardboard blank 3 are above and are thus visible to the operator.
  • Fig. 1 it can be seen that the rollers 54 are arranged around the transport drum 11 such that a total of three areas form the greatest approximation of the strands lying between the rollers 54 and the belt section abutting on the transport drum 11.
  • the groove cutting tools 72 may be arranged.
  • the Nutenschneidtechnikmaschinee 72 are mounted on parallel to the transport drum 11 support beams 36, 37.
  • Several groove cutting tools 72 may be mounted side by side.
  • Fig. 2a and 2b show the inventively designed Nutenschneidtechnikmaschine 72 Fig. 1 on an enlarged scale. It has a carrier 73, which can be fixed with a clamping piece 74 on the supporting beam 36. On the carrier 73 a via an eccentric 75a axially to the transport drum 11 finely adjustable carriage 75 is guided and fixable. The latter in turn carries a carriage 76, which is displaceable substantially radially relative to the transport drum 11 and can likewise be fixed by means of a knurled screw 76 a, on which the sheet guide 77 is located.
  • the center of curvature 81 of the sheet guide 77 is located in the cutting tip 71 a of the groove knife 71, virtually on the circumference of the transport drum 11.
  • the blade holder 78 can be adjusted to a different angular position according to scale 80 (see. Fig. 2a and 2b ).
  • the blade holder 78 and with it the grooving knife 71 by a through the center of curvature 81 and parallel to the transport drum 11 extending pivot axis pivoted.
  • the position of the cutting tip 71 a and thus their distance from the transport drum 11 do not change.
  • the depth of cut which can be set via knurled screw 76a remains constant, while due to the changed angular position of blade holder 78 on sheet guide 77, a different groove angle results.
  • a Ableitblech 82 for the costs incurred in Nutenbol chips 6 the front end is positioned as chip lifter to near the cutting tip 71 a of the notch 71 and at the other end in a the Nutenschneidtechnikmaschine 72 away and substantially radially to the transport drum 11 extending discharge channel 83 merges, which can be connected to a chip disposal device not shown.
  • the deflector 82 remains in its fixed position.
  • a poppie-down holder 84 is provided Upstream of the grooving knife 71. It is received separately from the blade holder 78 on a arranged on the sheet guide 77 holder 87 pivotally and presses by a compression spring 85 acted upon the cardboard blank 2 in the region of the groove knife 71 against the drum shell, whereby a properly cut on the card edge groove is guaranteed.
  • the pressing against the cardboard blank 2 end of the poppy lowermost 84 acts as a pressing element exclusively in the area of the subsequently cut out groove. Outside the pressure point, the poppy-down holder 84 widened to the deflecting plate 86 for chips that may possibly fall down during groove cutting.
  • the grooving cutter 72 is equipped with the one-piece grooved cutter 71. It is a knife with two connected to a V-shaped wings each outer ground blades 71 b, c, which are connected by a bridge to a closed ring body as chip removal channel.
  • the grooving knife 71 is very easy to grind and adjust over a simple sliding seat with respect to a constant cutting tip 71a on the blade holder 78. It is not necessary to set individual knife blades to each other.
  • the blades connected to the V lift the chips safely out of the groove 3a and guide them away from the cardboard blank 2 or the transport drum 11. By cutting the cutting tip 71 a can be cut with the grooving knife 71 and trapezoidal grooves.
  • Fig. 4 is known from the other figures knife holder 78 with the grooved knife 71 replaced by a the same interface to the sheet guide 77 having blade holder 78 ', which is equipped with two separate blades 88 a, b.
