Definitions

  • the tools supported by a circular device are in the form of annular sectors angularly movable so as to be able to carry out simultaneous operations in several places of the material to be worked, these annular sectors constituting either a tool for cutting is a repressor to work a material such as cardboard or corrugated cardboard.
  • said machines comprise an upper rotary shaft supporting circular devices equipped with cutting or pressing tools and a lower rotary shaft supporting circular counterparts placed opposite said circular devices mounted on the upper rotary shaft.
  • Cutting and upsetting tools will generally be called cutting blades and upsetting blades.
  • the blades being displaceable angularly around the circumference of the circular apparatus, it will be possible, using for example two non-adjacent cutting blades, to make two cuts per revolution of the rotary shaft, i.e. a cutting on the front and a cut on the back of a material plate.
  • the invention refers to a device for fixing tools on at least one circular device, in particular on a circular device which can be moved laterally along a rotary shaft supporting at least one circular device, said device for fastening comprising means for supporting said tools, means for holding tools against said means for supporting them and means for moving said means for holding tools, characterized in that the means for supporting the tools consist of a circular crown of which one of the faces is provided with circular housings distributed circumferentially over a constant radius having its center at the axis of the rotary shaft and by an internal toothed crown housed, so as to be able to rotate, in said circular crown, the toothed crown interior also being fitted on one of its faces of circular housings or bores distributed circumferentially over a constant radius also having its center at the axis of the rotary shaft, in that the means for holding the tools consist of a circular flange, one of the faces of which comprises two concentric grooves, said face of the circular flange being provided with at least one rod extending per
  • the device according to the invention has the advantage of holding the tools in position while allowing axial movement of the tool retaining means to cause the simultaneous opening of each consecutive device located on the rotary shaft, thereby allowing the accessibility to the tools so that they can be dismantled and reassembled easily and quickly.
  • circular devices A, B and C are placed side by side along a rotary shaft 1. Their lateral position depends on the places where operations, for example cutting or pressing, will have to be performed on a plate of material to be worked (not shown).
  • the circular devices A, B and C are provided, at their circumferences, with tools, in the particular case of the cutting blades 2 which can be adjusted angularly with respect to one another (see FIG. 3). It goes without saying that the number of circular devices 3 mounted on the rotary shaft 1 can vary as required and that the number of cutting blades 2 placed at the circumference of the circular devices A, B and C can also vary.
  • Each circular device A, B or C generally consists of a circular crown 4 keyed to the rotary shaft 1 and a circular flange 5 between which the cutting blades are disposed 2.
  • the circular crown 4 is equipped with an inner ring gear 6 meshing with a pinion 7 mounted on a shaft 8 passing through all the circular devices and rotating with them (see Figure 3).
  • the face 9 of the circular crown 4 has, at regular intervals and on a constant radius R having its origin at the axis of the rotary shaft 1, bores 10.
  • the toothed crown inner 6 is also arranged so as to have on its face 11 bores 12 of the same diameter as the bores 10. These bores 12 are also distributed at regular intervals over a constant radius R1 (see FIG.
  • the cutting blade 2 has on each of its faces a stud 22, respectively 23.
  • a stud 22, respectively 23 it is possible, by simply reversing the cutting blade 2, to obtain either a "fixed blade” version or a “movable or angularly movable blade” version.
  • the stud 23 engages with play in the concentric groove 21 which allows the clamping of the blade under the effect of the return spring or springs 18.
  • This arrangement has the advantage of being able to use either a fixed blade for a movable blade and vice versa.
  • FIG. 2 represents the circular devices 3 in their open position, that is to say in the position allowing the exchange of the different cutting blades 2.
  • the circular devices 3 can be moved laterally along the rotary shaft 1. This movement is carried out using a fork 24 engaging in a groove 25 arranged in the circular crown 4. It can therefore be noted that, if one moves, to the left of the figure, the circular apparatus B while maintaining the circular apparatus A in a given position, there will be a displacement of the circular ring 5 of the circular apparatus A. This displacement will create an opening 26 and the blade can then be easily removed 2 of the circular device A, and if necessary replace it.
  • All devices A, B and C are therefore open, it will be easy to dismantle the old cutting blades and replace them with new ones.
  • the pins 22 and 23 are sufficient to maintain the cutting blades 2 against the circular crown 4 but one could imagine ensuring this maintenance by equipping them, for example with magnetic pads 28 (see Figure 3).
  • the user of the invention has a device allowing rapid assembly and disassembly of the cutting blades or tools carried by one or more circular devices enabling him to perform in a very limited time the operations while thus ensuring a yield and an improved production rate of the machine thus equipped.
