Definitions

  • the same lifting mechanism in addition to conveying the empty trays to the proper magazine, also conveys the full trays from the magazine to the transfer mechanism.
  • a number of pneumatic cylinders are also provided for imparting movement to the various parts of the device, these pneumatic cylinders being actuated by sensing means such as limit switches and photocells.
  • the invention relates to a device for the automatic feeding of trays in synchronism with a cigarette packaging machine.
  • trays usually refers to the containers of cigarettes with which the machine is fed and which are essentially prismatic, with two open ends.
  • the capacity of each tray usually varies between 3,000 and 4,000 cigarettes.
  • tray-feeding has many drawbacks, one of which is the relatively long time required to replace an empty tray with a full one on the hopper of the packaging machine.
  • This drawback is due principally to the time required for the transfer device to take the empty tray to the special magazine for empty trays, collect a full tray from the magazine containing the full trays and transfer it on to the hopper of the packaging machine.
  • the term magazine refers to the supports in which the empty trays coming from the hopper of the packaging machine and also the full trays coming from the cigarette tray-filling machine are contained.
  • the magazine of full trays is situated on the same plane as that of the empty ones but on the opposite side. This naturally involves a loss of energy and/r time for manual loading and unloading of full and empty trays to and from the relative magazine.
  • the present invention of an automatic tray-loading device enables all the known drawbacks of tray feeding devices to be overcome.
  • the tray-loading device offers, for example, the advantages of having the magazine of full trays situated just above floor level, this magazine of full trays being located under the magazine of empty trays. This advantage permits a direct link-up of the tray-loading device to the trayfilling machine.
  • tray-loading device has at least one pair of tray containers which operate simultaneously, thus causing a considerable reduction in the time required to replace an empty tray, situated on the hopper of the packaging machine, with a full one.
  • FIG. 1 shows a side elevation of a tray-loading device according to the present invention
  • FIG. 2 shows a front elevation of the same tray-loading device as illustrated in FIG. 1;
  • FIG. 3 shows a side elevation of the magazines and the lifting mechanism of the tray-loading device illustrated in FIGS. 1 and 2;
  • FIG. 4 shows a front elevation of the magazines and the lifting mechanism of the tray-loading device illustrated in FIGS. 1 and 2;
  • FIG. 5 shows a side elevation of the transfer mechanism of the tray-loading device illustrated in FIGS. 1 and 2; 7
  • FIG. 6 shows a front elevation of the transfer mechanism of the tray-loading device illustrated in FIGS. 1 and 2.
  • this tray-loading device incorporates at least one pair of containers for the trays, which operate simultaneously in order to transfer full trays over the hopper of the packaging machine and transfer empty trays from the hopper to a lifting mechanism which then conveys them to the appropriate magazine.
  • tray-containers in pairs allows, in practice, to reduce the time required for the operation of replacing empty trays with full ones.
  • the tray-loading device substantially consists of a magazine for full trays 1, located below a magazine for empty trays 2, and a lifting mechanism 3 that conveys the trays to and from a transfer mechanism 4 which transfers the trays to and from the hopper of the packaging machine.
  • the transfer mechanism can be fitted with horizontal guides, so as to allow a horizontal translation and subsequent rotation of the containers, in pairs or separately, from the magazines of the tray-loading device towards the hopper of the packaging machine and vice versa.
  • the magazine 1 for full trays essentially consists of a metal frame at the base of which run two belt conveyors 11 and 12 actuated by a pneumatic cylinder 13 by way of a pulley 14. At its front end, magazine 1 also incorporates a support cradle 15 connected to a parallelogram linkage 16 actuated by a pneumatic cylinder 17.
  • a pair of guides 18, the position of which can be adjusted, are fitted on the upper part of magazine 1.
  • the guides 18 hold a plurality of trays 19, 19, 19", 19
  • each step being equal in length to the maximum depth of one tray.
  • the magazine 2 for empty trays essentially consists of a frame supporting a pair of fixed runners on which the empty trays slide, the direction of movement .being indicated by arrow B.
  • This transfer is facilitated by the fact that the front portions of the runners form an inclined surface, over which the bottom side of the tray slides, the tray being thus lifted when joining the other trays already present.
  • the movement of trays 19, 19' 19.7! sliding along the runners 21 is controlled laterally by a pair of adjustable guides 26.
  • the lifting mechanism 3 essentially consists of a pair of upright round guides 31 and 31' along which two sliding blocks 32 and 32' travel. These blocks 32 and 32' are fixed to a pair of chains 34 and 34' respectively. These chains, which can be substituted by any other known means, rotate also around sprockets 36 and 36' respectively.
  • the sliding blocks 32 and 32' are fitted with arms 37 and 37 respectively, at the upper end of which are the supporting pads 38 and 38' respectively.
  • the support pads 38 and 38 come in contact with the bottom side of trays 19 in both cases when travelling downwards with an empty tray.
  • the transfer mechanism 4 essentially consists of one or more pairs of containers 41 and 41' adapted to receive the trays. These containers are fixed to coupling plates 43 and 43' respectively, which in turn are hinged to connecting plates 42 and 42'. These connecting plates 42 and 42" are pivoted on shafts 44 and 44', respectively, these shafts being actuated by a rotary pneumatic cylinder 45.
  • Containers 41 and 41' are substantially prismatic and are opened at the top and bottom ends. The position of the openings in the containers is not critical but depends on the position of the tray-loading device with respect to the packaging machine.
  • the openings of the containers could be set laterally, so as to facilitate the introduction and removal of cigarette trays along a horizontal plane, during the transfer movement to and from the magazine.
  • each container there is a pair of small flaps 46 and 46' respectively.
  • the other open end of the containers 41 and 41' is closed by sliding lids 47 and 47' respectively, which are actuated by pneumatic cylinders 48 and 48 respectively, by means of two pairs of levers.
  • the whole transfer mechanism is supported by the two shafts 44 and 44', these shafts being connected in an articulated manner to arms 49 and 49' which rest on levers 50 and 50' keyed on rotating shaft 51.
  • another lever 52 connected to a pneumatic cylinder 53 is keyed onto shaft 51. Due to the action of pneumatic cylinder 53, the lever 52 transmits a rotary motion to shaft 51 which causes an angular displacement of lever 50, with consequent lifting of arm 49, of shafts 44 and 44' and, therefore, of the whole mechanism supported by the shafts.
  • the tray-loading device is also equipped with a pre-hopper 54 which contains a pair of shutes 55 and 55'.
  • This pro-hopper has also two holes 56 and 56' into which the receiving and transmitting elements, respectively, of a photocell are inserted.
  • the function of this photocell is to transmit the impulse required to start the operating cycle of the whole unit. The operating cycle will be described in more detail hereunder.
  • the beam of light emitted by the photocell transmitter is picked up by the receiver which in turn transmits an impulse to the control device of the cylinder 53.
  • the aforesaid cylinder causes the transfer mechanism 4 to lift to its upper position where a detecting device is located.
  • This device could be, for example, a micro-switch, a limit switch, a pneumatic device, a fluidic component or any other equivalent means.
  • the detecting device causes actuation of the rotary cylinder 45 which rotates the shafts 44 and 44 through By this rotation, the container 41, containing a full tray, is transferred to the position occupied in FIG. 1 by the container 41 which contains an empty tray. Simultaneously, the container 41' is transferred to the position occupied by container 41 in FIG. 1. At the end of the rotation, another detecting device causes the transfer mechanism to descend in such a way the full tray container, overturned during the rotation, is located over the opening of pro-hopper 54.
  • tray 19 with cradle 25 causes a detecting device to operate cylinder 22 which will move back cradle 25 towards the magazine 2 and thus transfer the empty tray over the runners 21.
  • the sliding blocks 32 and 32 continue their descent until they reach the lower end position of their downward travel, where they start the cycle of cylinder 17 which, when moving cradle by means of the parallelogram linkage 16, places the full tray resting on the cradle along the path of sliding blocks 32 and 32' (position 15' in FIG. 3). At this point, the sliding blocks start their up-,
