Definitions

  • the present invention relates to a device for grooving cardboard blank according to the preamble of claim 1.
  • Bookbases as well as boxes for high-quality sales and gift packaging consist of cardboard core covered with cover materials.
  • the cardboard blanks are grooved in the appropriate places.
  • the groove cross-section may have a triangular to rectangular profile, which is cut out of the cardboard as a chip with correspondingly standing knife blades or circular blades and possibly an interposed Aushebers or with one-piece, shaped according to the respective cross section special knives.
  • a generic cardboard groove machine is known in which the transport drum partially wrapped belt over each guide roller and a plurality of guide rollers and are tensioned by separate pressure rollers.
  • the side flanges equipped with guide pulleys are located on a common, rotatably mounted as the guide rollers in the frame shaft and keep the belt driven by the transport drum in certain axial positions to the transport drum, which are determined by the card size and the position of the grooves to be cut.
  • the object of the invention is to provide a groove device of the generic type, which can be quickly and easily converted to other board formats or changing groove layers.
  • the belt are on a radially displaceable to the transport drum, the first carrier.
  • the first carrier can be pushed back and forth between a working position and a radially away from the transport drum rest position. In the working position, the straps held in their respective position are stretched, while they are at least relaxed in the rest position and rest only loosely on the transport drum, so that the respective guide and tension rollers can be easily moved to other positions. With the pushing back of the first carrier in the working position, all the belts are tensioned simultaneously and the grooving device is immediately ready for use.
  • the second carrier may be displaceable radially and / or axially to the transport drum.
  • the second carrier are arranged axially displaceably on the first carrier to the transport drum.
  • the common radial displacement of the belt is taken over by the first carrier.
  • the second carrier can be fixed by clamping means on the first carrier. This is because clamping means can be released and activated quickly and enable stepless or rastered positioning of the second carriers or belts.
  • all rollers for guiding, for deflecting and for tensioning the preferably individual belt are arranged on the respective second carrier. It eliminates the range from frame wall to frame wall-reaching guide rollers and a respective second carrier can be removed as a whole for maintenance purposes, for example, to replace the belt from the groove device.
  • the second carrier each have a cantilever to one preferably single strap support arm on which the rollers are arranged in flying storage. This makes it easy to replace worn or damaged belts without having to remove a large number of components.
  • first and second rollers are respectively arranged at a distance in front of the inlet and / or outlet at the second carriers, so that the belts have a tangent to the transport drum respectively running from the transport drum strand.
  • third and fourth rollers are arranged on the second carriers such that the strand runs between these rollers at a distance of less than 10 mm, preferably less than 5 mm, past the belt section resting against the transport drum.
  • the grooving tools can engage over the adjacent belts and the actual grooving knives can be positioned very close to the belt without the belts hindering the discharge of the resulting shavings.
  • the belt force-path-dependent separately or tensioned, with the particular for tensioning roller is located at a force-loaded, movably arranged on the second carrier clamping lever or the respective roll is displaceably securable on the second carrier.
  • the first carrier is displaceable by adjusting means in its position to the transport drum.
  • the adjusting means can be operated manually or by motor. It may be a spindle-nut drive or include a control cylinder.
  • the adjusting means allow the positioning of the first carrier in the working position, the rest position and possibly any intermediate positions. In particular, the adjusting means allow variable working positions of the first carrier.
  • the first carrier can be fixed by adjustable latching means in its working position to the transport drum.
  • the respective working position can be approached quickly and safely. Due to the latching, the working position does not change under the working load of the groove cutting and / or the belt tension. With the adjustability of the locking means basic settings can be made.
  • At least one scale is provided on the first carrier for rapid and reproducible axial positioning of the second carrier to the transport drum.
  • both the belts and the groove cutting tools are located on the same first carrier which can be displaced radially relative to the transport drum. With the displacement of the first carrier in the rest position, the belts and at the same time the Nutenschneidtechnikmaschinee released for axial position adjustment. With the pushing back of the common first carrier, they are simultaneously brought into their working positions.
  • groove device 1 consists essentially of a driven, horizontally mounted transport drum 11 and a plurality of endlessly around rollers 54.1 to 54.8 rotating and spaced, the transport drum 11 to form an inlet 14 and a spout 15 partially wrap around belt 51 and between the belt 51st Nutenschneidtechnikmaschineen 72 arranged at a defined distance from the drum shell.
  • 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 lower vertex of the transport drum 11 lying inlet 14 for lying in the upper vertex outlet 15 promoted and passed past the Nutenschneidtechnikmaschineen 72 where Examgesc with appropriately shaped slot knives 71, for example, a V-shaped chip 6 from the cardboard blank 2 is cut.
