- a device of this type is known from French patent application No. 2 619 757 and relates to a marker assembly on which three plates and three inks are integrally mounted for marking in a single operation. This device operates by rotating the three plates, integral with each other, in a single direction of rotation, because they are arranged on a rotary axis co ⁇ nun.
- a vertically movable element causes the plate concerned to descend.
- this device is relatively complex, because in addition it implements a motor-belt-cam assembly and a torque limiter acting as a clutch during the printing phase. This is necessary because the three plates are integral in rotation.
- the object of the present invention is to remedy this drawback and for this purpose relates to a multicolor printing device of the type comprising at least two ink pads of different colors on which
- REPLACEMENT SHEET come into support two corresponding impression trays capable of being requested in printing by a mobile control device inserted in a fixed support frame for at least two-color marking, characterized in that the control device consists of a mobile transmission with vertical action capable of acting on impression tray arms articulated on corresponding fixed parts of the support frame and arranged on either side of said transmission member in such a way that an actuation of the latter in a up and down movement causes the successive angular tilting of the impression-holder arms around their articulations according to substantially circular and opposite trajectories taking place on either side of the vertical, the trajectory of a second support arm fingerprints being delayed relative to that of a first impression tray by auxiliary delaying means interposed between the org transmission donkey and the impression arms, these being brought back into their original position successively after printing, by means of elastic return members interposed between said impression arms and an element of the support frame.

- Two corresponding impression trays ⁇ and 5 may be requested for printing by a mobile control device which will be described later, inserted in a support frame 3, to ensure two-color marking.
- FIGS. 1A to II illustrate particularly well the operation of such a device according to the invention, the kinematics of which are as follows: - release of the impression trays and 5 relative to the ink pads 1 and 2 (FIG. 1B); rotation in the RI direction of the first impression tray ⁇ (FIG. 1C), until it has reached the vertical position placing the impression in the printing position on the support to be printed (FIG.
- the control device 10 comprises a handle 11 on which is exerted a manual or automatic pressure P and capable of acting on a mobile transmission member 12 with vertical action capable of act itself on the arms 8, 9 of the impression trays, 5 above.
- the vertically acting transmission member 12 consists of two elements 13, 1 one of which 13 leading and the other led lt are linked to the respective impression arms 8 and 9 and are capable of sliding longitudinally one in the other by means of an interlocking zone constituted by a groove 15 forming a mortise formed on one of the elements, in this case the driven element 1, opposite a tenon 16 corresponding on the other element 13, said elements 13 and 14 being initially capable of sliding simultaneously in a housing 17 of the chassis 3 by mutual drive under the action of an upper handle 11 until a first impression is made by a first impression tray 4.
- the handle 11 has an internal housing 24 allowing the vertical rise of the driven element 14 during its descent idarization with the driving element 13. More specifically, the operation of the control device 10 is as follows: action on the handle 11 according to a pressure P simultaneously causing the descent of the assembly of the transmission member 12 in the housing 17 of the chassis 3.
- the driven element 14 being longer than the driving element 13, it meets beforehand the impression arm 8 (FIG. 2B) which it drives to a vertical printing position (FIG.
- the impression arms 8 and 9 are articulated with respect to the fixed frame 3 by a common axis of articulation 25, but they are stressed by support points 26 and 27 respectively which are integral with them and located at different distances from the axis of articulation, as a function of the angular offset to be obtained.
- the control member 30 comprises a transmission member 31 with vertical action, consisting of a single element, of circular section 32 at its upper part and having at its lower free end part, opposite to a handle 33, a flat 34 of substantially semi-circular section.
- the vertical translation along F5 of the transmission member 31 takes place simultaneously with its rotation R5 in a corresponding sleeve 35 under the action of at least one fixed lug 36 of said sheath 35 cooperating with a helical peripheral groove 37 of the transmission member 31, so that the end phase 38 of said member which is perpendicular to the flat 34 is initially supported on a first impression tray arm 8 during a first phase of rotation R5 corresponding substantially to a half-turn, and this until meeting in its vertical and rotary stroke the second arm 9 of the impression tray, moment from which the first arm 8 escapes, according to a predetermined overlap, at the end face 38 of the flat part 34 of the transmission member 31, after having caused a first impression, the continuation of the stroke then acting only on the second arm 9 for a second impression.
- the rotation R5 of the transmission member 31 relative to the fixed handle 33 is obtained by means of a circlip 39 interposed between a groove in the member 31 and an internal groove in the handle 33.
- the impression arms 8 and 9 are articulated on joints 40 and 41 of the chassis 3, distinctly and angularly offset as a function of the delayed printing effects to be obtained.
- FIGS. 33 a detail of embodiment (fig. 33) concerning this same embodiment shows particularly well how the impression-bearing arms 8 and 9 are guided in their opposite semi-circular movements according to RI and R3, this is done by by means of corresponding semicircular grooves 43, 44 offset from one another and produced on at least one fixed side wall of the support frame 3, said grooves 43, 44 extending at their lower end by a vertical part 45, 46, such that the respective joints 40, 41 of each arm 8, 9 of the impression trays, after having described alternately a semi-circular movement along RI, R3, carry out a vertical stroke FI, F3 corresponding to the actual printing phases of the impression trays.
- FIGS. 33 a third embodiment shown in FIGS.
- the control device 50 comprises a transmission member 51 with vertical action constituted by a single bar of uniform section capable of moving laterally along F5 simultaneously with its vertical movement along F6 , under the influence of a fixed ramp 52 of the support frame 3 on which abuts the end phase 53 of said bar 51, so that during its descent it causes in its passage a first arm 8 of impression tray then a second arm 9 of a second impression tray, offset with respect to the first 8, which arm 8 escapes laterally, after printing according to FI, from said bar 51 which continues its vertical stroke along F6, without further lateral influence along F, along a straight portion 54 following the ramp 52 to drive the second impression-carrying arm 9 towards a second impression in a final vertical stroke along F6.
- the low impression trays 8 and 9 are guided in their semicircular movements as shown in f ig. 33 previously described.
- the control device 60 consists of a movable transmission member with vertical action 61 constituted by a bar provided with two opposite racks 61 and 62 cooperating with two corresponding toothed pinions 63 and 64 freely mounted on the same axis 65, so as to transform a vertical linear movement F7 and F8 of each rack 61 and 62 into a rotary movement R7 and R8, of said pinions 63, 64 respectively integral with two cams 66, 67 of opposite eccentricity rotating in opposite directions in directions also opposite R9, RIO and angularly offset with respect to each other so that their opposite rotation R9, RIO successively drives the impression trays 8, 9 towards a vertical printing position, by guiding respective lugs 68, 69 which are integral with them ⁇ in a semicircular groove 70 formed in a fixed part of the support frame 3.
- This semi-circular groove 70 is used partly by the lug 68 of the arm 8 and partly by the lug 69 of the arm 9, the intersection of these two parts being materialized by a portion of vertical groove 71 corresponding to a stroke vertical printing of the arm 8 according to FI and successively of the arm 9 according to F3.
- the impression-carrying arm 8 undergoes an action in the direction FI by translation of its lug 68 in the vertical groove 71 to make a first impression.
- the cam 67 continuing to rotate along RIO begins to influence in rotation along R3 the arm 9 of the second impression tray (FIG. 5C); -
- the cam 66 continuing its rotation along R9 causes the lug 68 to escape from the impression-carrying arm 8 which returns to its initial position under the influence of its return spring.
- the impression arm 9 influenced by the contact of the cam 67 begins its circular movement along R3 by guiding its lug 69 in the groove 70 (FIG.
