<p>The numbering machine comprises a series of cams (2) and a series of wheels (3), each cam (2) being connected with a wheel (3), so that the turning of a cam (2) signifies the turning of a wheel (3). The cams (2) have on their periphery nine projections (17) and a recess or hollow (18), while each wheel (3) has on its periphery the digits corresponding to the first nine numbers. The assembly is mounted in an interior casing (1) from which a spindle (4) emerges operable sequentially in each process of injection of a piece, so that through that spindle (4) and by means of a lever (8) articulated thereto individual arms (10) and (11) are operated, the first of them having a toothed sector (14) the teeth of which are pushed for each tooth to press on a single cam (2) until the complete turn takes place, the interlocking taking place of a second tooth with the second cam (2) and so forth, so that in each sectorial turning of the cam (2) the sectorial turning of the respective wheel takes place (3) and therefore the sequential advance of the corresponding number. The arm (11) has a series of prongs (15) which maintain the wheels (3) immobilised with the exception of that which is operated by the corresponding cam (2). The numbering machine is foreseen for marking pieces obtained by injection.</p> |
