  • the other end of the side walls idly support said shaft 16.
  • the angular position of the side walls 18 about the axis of the shaft 14, and therefore the level of discharge of the envelopes 2 form the chains 11, is determined by a bridge support 19, which is mounted on a bracket 20 which will be described hereinafter.
  • Pins 22 are engaged in vertical elongated slots 21 in the arms of the support 19, and these pins also engage in longitudinal elongated slots 23 in the side walls 18, so forming a link engagement between the side walls and the support.
  • the teeth 10 of the lower branches of the chains 11 advance in the direction indicated by the arrow B, and drag the envelopes along the underlying segments 24 which are aligned with the segments 3.

  • the segments 24 and tracks 25 are supported parallel to the lower branches of the chains 11 by the side walls 18 and terminate at the upper aperture 26 of a drum 27-28, so that the envelopes 2 enter the same aperture flatly one after the other.
  • the drum consists of two annular vertical plates 27, with each of which is rigid a cylindrical wall 28 having an horizontal axis transverse to the transfer conveyor 1, 12.
  • the two cylindrical walls 28 which have the same radius and projectagainst one another from the plates 27 are preferably transparent.
  • the plates 27 are centrally traversed by the shaft 29 and their position along this shaft can be adjusted by four pins 30 which are parallel to the shaft 29 and project from a part 31 (FIG. 4), of a casing 32 (FIG. 2) which is rigid with said bracket 20.
  • a plate 36 provided laterally to the bracket 20 and supported in a cantilever manner by the arm 36a, comprises at its front vertical sleeves 37 in which the rod 38 is slidably guided, by way of bushes of friction material.
  • the plate 36 and rod 38 are located between the opposite plates 27.
  • the rod 38 supports the tray 39 in a cantilever manner, located under the inlet aperture 26 of the drum 27-28 and forming a mobile base for the seat formed by the pair of stirrups 34, and which when at rest is immediately under the aperture 26.
  • the ends 39a of the tray 39 are restricted so that they can pass through corresponding openings in the bases of the elements 35. in this man ner, as shown by the dashed lines in FIG. 4, the tray can descend slightly under these bases.
  • rocker arm 40 acts against the lower end of the rod 38 for raising the tray 39 as far as the aperture 26.
  • the rocker arm 40 is pivoted at 41 to an appendix of the bracket 20, and its other end is linked to a tie rod 42 which is linked at 43 to the rocker arm 44 (FIGS. 2 and 3).
  • the rocker arm 44 is pivoted at 45 to the inside of the casing 32, and at its free end carries the roller 46 which, as explained hereinafter, engages with the shaped edge of the cam 47.
  • Normally rocker arm 44 is kept resting, by a spring not shown, against an abutment which is also not shown.
  • the arm 48a of a rod bent in the form of an inverted U descends towards the aperture 26.
  • the arm 480 carries lowerly the pushing plate 49 which penetrates into the aperture 26.
  • the other vertical arm 4812 (FIG. 2) of said rod is slidably guided in casing 32. inside the casing the a clamp 50 is fastened on the arm 48b and is articulatedly coupled at 51 to the tie rod 52, which is articulatedly coupled to the lever 53.
  • This lever is pivoted at 54 to the casing 32 and supports the roller 55 which is always in engagement with the frontal shaped groove of the cam 56 keyed on to the shaft 57.
  • the shaft 57 parallel to the shaft 29 and rotatably supported by the casing 32, is rotated continuously.
  • the pushing plate 49 makes an ascent-descent stroke with the same frequency as the packaging machine. In this manner as soon as an envelope 2 arrives at the aperture 26, the pushing plate 49 descends, engages the envelope and drags it downwards for a distance practically equal to the thickness of the envelope.
  • the envelope penetrates into the underlying seat formed by a pair of stirrups 34 and elements 35 and lies on the pile of other envelopes already there.
  • the tray 39 supporting the pile of envelopes descends through a distance equal to the thickness of one envenope as the friction between the rod 38 and its guides is overcome by the thrust exerted on the envelopes by the pushing plate 49.
  • the pushing plate 49 has carried out its descending stroke, it rises again so as not to interfere with the new arriving envelope.
  • the control means in the casing 32 receive their motion from the shaft 58 which is driven with continuous rotation by the motor of the packaging machine and is idly supported by the casing itself.
  • the shaft 58 ends with the bevel gear 59 which is keyed on to it, and which engages with the bevel gear 60 keyed on to the shaft 61.
  • the shaft 61 is parallel to the shafts 29 and 57 and is rotatably supported by the casing 32.
  • the same shaft has keyed on to it an axial cam 62 and a gear 63 which engages with the gear 64 keyed on to the shaft 57.
  • the disc 65 is rotatably rigid with the shaft 57 but can slide axially on it.
  • the disc 65 is rigid with the cam 47 by means of an intermediate bush comprising an annular groove 66.
  • a radial arm is fixed to the disc 65 and carries at the end external to the disc a roller 67 which engages and drives the Maltese cross 68 keyed on the shaft 29, when the disc 65 is at the end of the working stroke in which the cam 47 is engaged by the roller 46.
  • the roller 67 and cam 47 are inactive although rotating, the Maltese cross cannot rotate because it is engaged by the periphery of the disc 65.
  • the periphery of the disc 65 there is a cavity in the form of a sector 65a, which enables the Maltese cross to rotate when it is engaged by the roller 67.
  • the groove 66 is engaged by the pin 69 coupled to one end of the lever 70, which is fixed to the shaft 71 supported in an oscillating manner by the casing 32.
  • a roller 72 which engages with the cam 62 under the action of the traction spring 73, the ends of which are fixed to an appendix of the lever and to the casing 32.
  • the lever 74 is also rigid with the shaft 71, and normally rests on a tooth 75 which can assume a withdrawn position by the action of an electric magnet 76.
  • the energizing of the electric magnet is controlled by a counter, not shown, which receives the impulses fed by a device sensitive to the envelopes which arrive at the aperture 26 dragged by the chains 11.
  • the counter When the counter ascertains that the number of envelopes which have reached the aperture 26 is sufficient to fill the seat 34, 35 located under it, the counter energises the electric magnet 76 so causing the tooth 75 to withdraw. In this manner the lever passes under the control of the cam 62 which brings the disc 65 to said end of the working stroke.
  • the Maltese cross 68 and the shaft 29 thus make one-quarter of a turn in the direction indicated by the arrow C, and a new seat to be filled is brought under the aperture 26.
  • the cam 47 immediately causes the support tray 39 to rise for supporting the new pile of envelopes.
  • the lever 74 is returned upwards by the cam 62 and can thus again hook on to the tooth which, as the electric magnet 76 becomes de-energized, reassumes the extracted position under the action of a not shown return spring.
  • the group of envelopes formed in the filled seat must now be discharged. According to requirements, the group has to be discharged either with the envelopes face downwards or upright.
  • the discharge position must always be the same as the inlet position of the known cartoning machine, in which the envelopes are introduced in boxes and which is disposed beside the drum 2728 on the side opposite the casing 32. This position is indicated by D.
  • the expulsion of the envelopes from the seat takes place when the seat is at rest in a position at 180 to the position in which it was filled.
  • expulsion takes place when the seat has reached a position at 90 to the filling position.
  • the bracket is lowered and laterally displaced towards the first portion 1 of the transfer conveyor.
  • the bracket 20 is in fact slidably guided vertically in the upright 77, and its position can be adjusted by a screw the handwheel of which is indicated by 78.
  • the upright 77 is guided on the bed '79 and is slidable with respect to it in the horizontal direction parallel to the transfer conveyor 1, 12.
  • the position of the upright 77 in respect to the bed 79 can be adjusted by the screw 80, using the operating handwheel 81. Because of the two positions which the bracket 20 can assume, the shaft 58 is driven from the drive system of the packaging machine by means of a transmission system comprising at least one chain.
  • Apparatus for forming groups of flat objects which are transferred individually from a transfer conveyor comprising a drum of horizontal axis consisting of a cylindrical wall provided with an upper aperture, and two parallel plates provided with opposing apertures dis posed in diametrical positions at right angles to the upper aperture, a shaft driven with intermittent motion and supported coaxially to said drum, a plurality of seats angularly distributed on said shaft and disposed between said plates, said seats opening radially outwards and axially towards the plates in such a manner that at each angular movement of the shaft, said seats are accessible through the upper aperture of the cylindrical wall and the opposing apertures of the plates, a support tray for the objects acting as a mobile base for the seat accessible through the upper aperture, said tray being made to descend in steps equal to the thickness of the objects from a position close to the upper aperture of the cylindrical wall to a position close to the support shaft for the seats, and push means driven parallel to said shaft and penetrating through the opposing apertures of the plates for expelling the objects from
