Definitions

  • Said i means coupling the plunger and the [58] Fleld of Search ..222/1, 2, 333, 386 cigarette maker for driving Said plunger toward said orifice at a rate commensurate with the demand for [56] References c glue of the cigarette maker, and means coupled to the UNITED STATES PATENTS plunger independent of the cigarette maker for driving 'said plunger toward and away from said orifice.
  • This invention relates to glue dispenser units and more particularly to glue dispensers used in cigarette making machines to apply a film of glue along one edge of the paper tape that receives the tobacco braid in order to enable the closing and sealing of the tape around the braid to form the continuous rod from which the individual cigarettes are cut.
  • a glue dispenser unit generally comprises means for applying a thin film of fluid glue on an edge of the cigarette paper tape and dispenser means for feeding the glue to the aforementioned glue applying unit.
  • the glue applying means and the glue dispensing means are interconnected by a suitable duct or hose or the like. This arrangement allows the glue applying unit only to be placed in the rod forming area while the glue dispensing unit, which is somewhat larger, to be located in a more suitable or convenient position for the service and/or maintenance thereof.
  • the glue feeding means or dispenser, consists of a cylindrical housing within which a plunger is mounted for slidable movement.
  • the plunger is coupled to the cigarette maker proper to assure a flow of which is proportionate to the cigarette maker rate of production.
  • an improved glue dispensing unit may comprise a cylinder having an outlet orifice therein, a plunger mounted for slidable movement in the cylinder and operable to dispense glue out said oritice, means coupling the plunger and the cigarette maker for driving said plunger toward said orifice at a rate commensurate with the demand for glue of the cigarette maker, and means coupled to the plunger independent of the cigarette maker for driving said plunger toward and away from said orifice.
  • FIGURE of the drawing is a perspective view of a glue dispensing unit according to the invention with parts thereof broken away.
  • a preferred embodiment of the invention comprises a glue cylinder 1 having a plunger 2 mounted for slidable movement therein and a glue dispensing orifice 101 adjacent the top thereof.
  • the glue is disposed above the plunger 2 and the upward movement thereof in cylinder 1 dispenses glue from the orifice 101.
  • a piston rod or stem 3 having a threaded section 103 and a longitudinal groove 203 is rotatably mounted to the plunger.
  • the plunger 2 is normally moved upwardly in cylinder 1 to dispense glue by a drive chain A coupled to the cigarette maker.
  • Drive chain A includes an eccentric 4 mounted on a driving element of the maker, a connecting rod 5 mounted on the eccentric, the other end of which is connected to a crank, 6.
  • the crank 6 is keyed to a shaft 7a having a toothed wheel 7 thereon that meshes with a second toothed wheel 8.
  • the second toothed wheel 8 is mounted on a shaft 8a having a worm screw 9 mounted on 'the other end thereof that meshes with a helical wheel 10.
  • a threaded section is formed in the inside of the hub wheel 10 and the threaded section 110 is mounted on the threaded section 103 of piston rod or stem 3.
  • the wheel 10 is mounted to the frame of the device with the quantity of glue normally required by the machine and the elements of drive arrangement A are so chosen and sized.
  • Actuating mechanism B comprises a reversible electric motor 11 having an output shaft 11a.
  • a pulley 11b is mounted on output shaft 11a and a pulley 13a is mounted on a shaft 13b mounted in spaced relationship with shaft 11a.
  • a drive belt 12 drives shaft 13b from output shaft 11a.
  • a worm screw 13 is mounted on shaft 13a and meshes with a toothed wheel 14 with helical toothing. Toothed wheel 14 is mounted around stem 3 and is supported in such a way as to rotate about the axis of the stem 3, without moving longitudinally therealong.
  • the toothed wheel 14 includes a hub portion 14a that is provided with an inwardly extending tongue 15 that is mounted in the groove 203 provided in the stem 3 to transfer rotational movement of toothed wheel 14 to the stem.
  • the motor 11 can be coupled to the cigarette maker such that it starts running automatically when the maker is started and both drive arrangements, A and B, drive the plunger 2 upwardly to impose a pressure on the glue in the cylinder.
  • motor 11 is not coupled to the maker and can be actuated while the maker is off to impose pressure on the glue before the maker is turned on so glue can be dispensed immediately upon the commencement of the making sequence.
  • a pushbutton P1 While the cigarette maker is running, the operator can, by means of a pushbutton P1, run motor 11 in such a way as to increase the glue pressure in the pot, since, as stated. above, the coupling of the mechanism B driven by motor 11 to the stem 3 is additive to the coupling of the mechanism A from the cigarette maker to the stem 3. Conversely, the actuation of a pushbutton P2 causes motor 11 to rotate in such a way as to lower plunger 2 in cylinder 1.
  • a disk or flange 19 integral with the lower end of stem 3 engages a fork 120 which receives the stem 3 between its tines.
  • Fork 120 is mounted on a rod 20 which is mounted parallel to stem 3 and is maintained elastically balanced between two helical positioning springs 220 acting in opposite directions against the fork 120.
  • a crank pin 121 rides in a notch 20a provided in rod 20 and is mounted on shaft 21a driving a cam 21.
  • the engagement of disc 19 with fork 120 causes the upward displacement of the latter and a consequent axial upward sliding of rod 20. This sliding causes an angular rotation of crank 121 whereby cam 21 rotates in such a way as to actuate a microswitch 22 included in a circuit which stops the maker or motor 11.
  • the motor 1 l is run to lower the plunger 2 in its position out of the lower end of the empty cylinder. In this position, plunger 2 engages the top free end of rod 20, whereby the rod is caused to slide downward against the action of positioning springs 220 and the consequent rotation of crank 121 causes cam 23 to actuate microswitch 24. The actuation of this microswitch causes motor 11 to stop. The empty cylinder can then be substituted with a full one and subsequently the cigarette maker can be re-started.'
  • a double cylinder and plunger unit can be provided according to the invention, each associated with actuating devices as set forth above.
  • the depletion of the glue in one cylinder does not necessitate the stopping of the maker.
  • the signal from actuation of the microswitch 22 at the end of the upper stroke of plunger 2 can be used to cause the switching of the coupling of the glue applicator from one dispenser to the other.
  • non-retum valves could be provided in the delivery ducts of the cylinders.
  • Apparatus for dispensing liquids which comprises:
  • a plunger mounted for slidable movement in the cylinder
  • first means coupled to the piston rod for driving the plunger toward the orifice
  • Apparatus for dispensing glue for use with a cigarette maker which comprises:
  • a plunger mounted for slidable movement in the cylinder and operable to dispense glue out said orifice
  • a method of dispensing glue for use in a cigarette for driving said plunger toward said orifice at a 5 making operation comprising the steps of:
