Definitions

  • the present invention relates to a composter for an engraving press, more specifically a composter intended to be assembled to the tool holder of the press by a shank and comprising two parallel flanges between which pivots an axis carrying a plurality of knurls and their wheels with ratchet and a rocker formed by two parallel levers pivoting around said axis between a high position and a low position and carrying a spacer axis on which manipulators can pivot, each comprising at one end a spout capable of being engaged against the action of a spring wound on the spacer axis, in the corresponding ratchet wheel, under the effect of a pressing pressure on the opposite end of the selected manipulator, after which the rocker is caused to pivot from its high position to its low position, rotating the ratchet wheel and the wheel corresponding to the selected manipulator.
  • a composter of this type is known from GB-A-2 028 723.
  • the composter according to this British document comprises on the one hand a pneumatic device for selecting manipulators using a finger acting on the end of the manipulator opposite the spout engaging in the corresponding ratchet wheel and on the other hand an actuating device constituted by two double-acting cylinders acting at the level of the spacer-axis carrying the levers and the manipulators to cause the pivoting of the assembly for the rotation of the wheel concerned.
  • the two double-acting cylinders act at the two ends of the spacer axis.
  • the composter described in the British document is complex and difficult to implement, in particular due to the difficulty in synchronizing the movements of the two jacks, the absence of synchronization resulting in constraints, in particular at the level of the axis- spacer and components mounted on it, causing rapid deterioration of the assembly.
  • the present invention proposes to avoid these drawbacks and to produce a particularly simple and reliable composter, in particular requiring no separate actuating device to cause the selected wheel to rotate.
  • each of the rocker levers comprises an elastic return member in the high position, the pivoting of the rocker from the high position to the low position being effected by pressure bearing on said opposite end of said selected manipulator engaged by its spout in the ratchet wheel corresponding to the wheel to be driven in rotation.
  • the selection of the wheel as well as its rotational drive are obtained by pressing pressure on the end of the corresponding manipulator, this pressing pressure successively making it possible to engage the opposite end shaped as a spout of the manipulator in the ratchet wheel associated with the thumbwheel and this against the spring provided on the spacer axis and tending to release this spout from the ratchet wheel, this pressing pressure then causing the pivoting of the rocker and the rotation of the corresponding wheel, the rocker being then automatically returned to the high position by means of the elastic return member with which the levers constituting it are provided.
  • the composter according to the invention comprises various conventional arrangements.
  • It comprises a cage C in U formed by two flanges CI-C2 connected by a ceiling C3 carrying the tail QA intended to be fixed in the tool holder of the engraving press. Swiveling on an axis AX1 clipped externally to the flanges C1-C2, there are on the one hand the knobs M0, each being integral with a ratchet wheel RR (whose unidirectional rotation is ensured by ratchets CL with spring) and, on the other hand two levers L1-L2 connected to each other by an axis-spacer ET with which they constitute the rocker.
  • knobs M0 On this axis ET spacer, as many manipulators MA1 (MA2 ... MA6) are articulated as there are knobs M0.
  • Each manipulator has one end shaped as a TO key, the other end being shaped as a spout BC intended for cooperate with the notches of the corresponding ratchet wheel RR.
  • a pin spring RM Surrounding the axis ET, in an intermediate position, is placed a pin spring RM separating the beak of the manipulator concerned from the ratchet wheel, therefore in the opposite direction of the rotation of the latter.
  • Each manipulator comprises an oblong eye MD intended to accommodate said spring RM and a second spacer ETR of the rocker on which the spring rests.
  • the actuation of a ratchet wheel RR is done by pressing on the end TO of the selected manipulator, which moves the rocker LI- L2-ET towards the bottom by rotation around the axis AX1.
  • springs are interposed between the levers L1 and L2 and part of the cage C.
  • the levers L1-L2 comprise a housing L3 opening on their dorsal face and of which a wall L4 is radial.
  • the cage C is crossed by an axis AX2 clipped beyond the flanges C1-C2.
  • This axis AX2 carries at least one spiral spring RS wound around it and the branches of which support one on the ceiling CP of the cage C, the other on the wall L4 of the housing L3. Building on this ceiling CP, the spring RS therefore tends to oppose the downward movement of the levers L1-L2 and brings them back to the high position when the pressing on the selected manipulator stops.
