Definitions

  • This invention relates to the automatic machines used for the wrapping of products formed of discrete articles, particularly caramels, in which the feeding apparatus comprises a horizontal, or substantially horizontal, disc which rotates around its axis and is provided with equally--spaced seats at the periphery of on an imaginary circumference having the center at said axis of the disc, said seats being dimensioned and shaped so as to accommodate only one caramel within each of them.
  • a feeding apparatus usually comprises an elevator member or elevator which, with a suitable timed sequence, moves upwards through each of said seats, one at a time, and which, in co-operation with a counter-elevator arranged above, lifts said caramels to transfer them to an upper station where said caramels are wrapped in a suitable wrapper.
  • a wrapper is automatically laid on said caramel and will be thus held thereon by said counter-elevator.
  • said wrapper tends to fold down on said caramel and then it is transferred between upper side-clamping means - which take the place of said elevator and counter-elevator that are timely returned to their initial position to repeat a new cycle - in the best condition to be folded over completely around the caramel and sealed thereon.
  • the lifting movement of a caramel and its wrapper usually occurs along a straight vertical path of travel, to avoid undesired distortions of the wrapper and to permit both a high-speed operation and a constructional and functional simplification of the clamping and transfer means for a caramel.
  • the lowering movement of the elevator may occur in combination with the operative movement of the feeding disc, thus permitting a higher efficiency of the feeding apparatus, the lifting movement of said elevator inevitably implies a stop of the feeding disc in order to avoid any interference between said disc and the stem of said elevator.
  • the stem of the elevator is formed with an inclined configuration with respect to the vertical, whereby during the lifting step thereof through a seat of the feeding disc, said stem presents parts having a progressively increasing distance with respect to the vertical axis of the lifting path, so that the displacement from said axis occurs in the same direction, or substantially the same direction, as the movement of the periphery of the feeding disc, as if said stem of the lifter (during its lifting stroke along the vertical) moved with respect to the seat through which it is travelling, in the same direction as the rotation of the feeding disc, so that said disc may go on rotating even during the lifting step of the elevator, with resulting obvious advantages.
  • the feeding disc need not be stopped cyclically, but it can be actuated with a continuous and various motion, with minimum acceleration and de-celeration which, anyway, is necessary to facilitate the entry of caramels into said seats in the disc, thus ensuring a higher efficiency of the feeding apparatus.
  • reference letter D indicates a feeding disc which rotates in the direction of arrow F
  • S indicates one of the seats which are formed on the periphery of said disc, said seats lying on an imaginary circumference the center of which coincides with the axis of rotation of said disc.
  • Each seat is shaped and dimensioned so that only one caramel P can be accommodat therein, each caramel being retained in said seat by an underlyinf fixed guide G ending at the point where the elevator shall work.
  • the said elevator shall be positioned in a proper timed sequence under the caramel P and shall be lifted through the seat S to transfer said caramel to the wrapping station. Thereafter the elevator is returned to its lower or rest position to repeat a new cycle.
  • the elevator comprises a head 1 having a surface proportioned to the size of the product ? to be handled.
  • the stem 2 of the elevator has a reduced section in order to get through the seat S with the maximum possible clearance, and is characterized in that it has an inclined shape so that, with respect to the vertical central axis Z of the head 1, the distance of said stem 2 increases progressively in such a manner that said stem and axis diverge downwardly.
  • the imaginary plane comprising the axis Z and the longitudinal axis of the stem 2 is perpendicular to the disc D and is tangent or secant to the imaginary circumference on which said seats S are located.
  • the stem 2 of the elevator is positioned ahead of said axis Z.
  • the stem 2 of the elevator may have any other equivalent form, such as a stepped or a curved form.
  • the stem 2 is associated to any supporting and driving means 3 adapted to impart to said elevator a vertical displacement as indicated by the arrows F2-F2' and a further displacement, first in the direction F3, i.e. the direction of rotation F of the disc D, and then in the opposite direction F3'.
  • a possible embodiment of said supporting and driving means 3 will be described hereinafter.
  • the elevator is simultaneously moved in the directions of the arrows F2' and F3 firstly, and F2' and F3' subsequently, so that the head 1 of the elevator is moved, as a resultant, along the portion X3 of the diagram of Figure 1 r while the disc D continues moving in the direction F,and is returned to the originary position for a new cycle under a new product P which has been transferred in the meantime by the feeding disc D to the wrapping station.
  • the return movement of the elevator entails no particular problem inasmuch as the elevator is now devoid of the product and, therefore, it may be subjected to rapid accelerations and de-celerations.
  • the counter-elevator C is lowered to repeat a new similar cycle.
  • An outline of the counter-elevator can be seen in Figure 2, and since this member is only lifted and lowered along the vertical axis W in a conventional manner, a detailed description thereof will be omitted.
  • the elevator E effects first a stroke to follow the feeding disc and then a stroke in the opposite direction by traveling on an arc of circumference having its center on a vertical rod 4 supporting at its upper end an arm 5 mounting the stem 2 of said elevator.
  • the rod 4 is supported, so as to rotatable and axially movable, by a fixed structure 6 provided with bearings 7-7'.
  • the rod 4 is moved axially by a bell-crank lever 8, and is connected thereto by a suitable pivotal joint 9, said lever being pivoted at 10 to the frame 11 and being pivotably connected to a fork--member 12 which is reciprocated by a cam 13 through cam--followers 14.
  • the fork-member 12 is guided to move longitudinally by a mounting block 15 rotatably mounted on the cam-shaft 16.
  • This cam-shaft also mounts a drum-shaped cam 17 co-operating with a cam-follower 18 provided at the bottom end of a vertical guide 19 swingably supported in by a shaft 20 which is parallel to the rod 4 and is supported on stationary portions of the frame 11.
  • a sliding member 21 is slidable in the guide 19, and pivotably connect thereto at 22, parallelly to the shaft 20, there is an arm 23 which is secured at 24 to an intermediate portion of the rod 4.
  • This arrangement causes the rotational movement of the rod 4 while permitting said rod to move axially.
  • the elevator may be moved by utilizing means which can be different from that described above, and that many constructional changes and modificatio: may be made, without departing from the scope of the invent as set forth above, as illustrated and as claimed hereinaft
