Definitions

  • the labeling apparatus has a source of labels, a
  • gripping turret with mechanical gripping elements that withdraw labels from the label source and fly the labels against the glue retaining surface of a gluing drum, en route to apply the labels to containers.
  • the mechanical grippers are so arranged as to grip only the leading edges of the labels.
  • Optional airjet nozzles may blow the flying label portions against the glue drum.
  • the glue drum is provided directly with a doctor blade which spreads glue onto a uniform film on the drum.
  • the drum is provided with recesses to receive the mechanical gripping elements below the glue drum surfaces as the gripping elements sweep past the drum.
  • the label is gripped only at its leading edge and label portions trailing the gripped leading edges fly in unsupported relation to the turret.
  • the label is flown past the glue transfer surface and kisses it or contacts it lightly without the positive pressure of a pressing pad.
  • the gluing drum has recesses aligned with the mechanical gripping elements on the turret so that the gripping elements do not contact the glued surfaces of the drum.
  • the gripping turret and glued drum are spaced apart.
  • air nozzles can be provided to blow the trailing portions of thelabel against the glue drum to provide a light yielding pressure to facilitate transfer of a glue film to the label.
  • a doctor blade is applied directly to the gluing drum to insure the development of a uniformfilm' of glue on the drum.
  • this doctor blade is provided with projecting tongues which will fit into the peripheral grooves in the drum to clear the grooves of glue.
  • the grooves are aligned with the gripping elements to receive these elements beneath the drum periphery, thus to avoid pressing the gripping elements against the glued surface of the drum.
  • the drum is provided with a continuous surface with socket-type recesses to receive the gripping elements and a straight edge doctor blade. This surface applies an over-all film of glue to the label.
  • the sockets are provided with retractable plungers which are projected to beflush with the periphery of the drum as the drum passes the doctor blade. The plungers are retracted to expose the sockets to the gripping elements as the sockets pass the gripping elements, thus to insure that no glue is transferred to the gripping elements.
  • the glue doctor blade of the present invention is novel, per se, in that it incorporates at its head end the glue nozzle'by which glue is applied directly to the gluing drum, without need for intermediate transfer rollers or the like.
  • FIG. 1 is a diagrammatic plan view of the general layout of labeling apparatus in which the invention can be incorporated.
  • FIG. 2 is a fragmentary side view of a label feeder and gripper turret.
  • FIG. 3 is a side view ofa peripherally grooved gluing drum and a fragment of the gripping turret adjacent and in spaced relation thereto.
  • FIG. 4 is a plan view of the apparatus shown in FIG. 3, portions being broken away to expose interior details.
  • FIG. 5 is a side view similar to FIG. 3, but showing a modified embodiment of the gluing drum in which peripheral grooves are replaced by sockets.
  • FIG. 6 is a plan view of the apparatus shown in FIG. 5, portions being broken away to expose interior details.
  • Containers such as bottles 31 are fed by conveyor 1 past a spacing worm 3 into a turning star wheel 2 which feeds the containers onto a labeling turret 6 which rotates on its axle 24 in the direction of the arrow.
  • Discrete pre-cut labels 13, 13a on the label grippers or turrets 7, 7a are applied to the containers 31 which subsequently leave the labeling turret 6 via an exit star wheel 5.
  • Labels 13 are body labels, and labels 13a are neck labels. They are stored in label magazines 12, 12a.
  • Guide 4 retains the containers 31 in the star wheels 2, 5 as the containers negotiate the turns between conveyor 1 and turret 6.
  • the gripper turrets 7, 7a rotate on shaft 22.
  • the rotary label feeders 10, 10a have peripheral grooves 14 which align with the mechanical gripping fingers 16 to admit the fingers for picking up the labels.
  • the control of the suction applied to the labels through the ports 15 is coordinated with the mechanism which mechanically actuates the gripper 16.
  • the grippers 16 are mounted on shafts 17 having cranks 18 which carry cam follower rollers 20 which rotate on roller shafts 19 and roll on the periphery of a cam plate 21 to open and close the fingers 16 with respect to anvils 25, thusto effectuate a smooth transfer of the labels from the rotary label feeders 10, 10a to the gripper turrets 7, 7a.
  • Each set of grippers 16 cooperates with a corresponding set of anvils 25.
  • the grippers engage only the leading edges of the labels 13, 13a, as is illustrated in FIGS. 4 and 6.
  • the anvils 25 have their heads spaced radially outwardly from the peripheral surface of the pads 29 which define the periphery of the gripper turret. Accordingly, those portions of the labels which trail their gripped leading edges fly in unsupported relation to the gripping turret.
  • Gripper turrets 7, 7a rotate in spaced proximity to rotating glue drum 8.
  • the glue carrying periphery of the drum 8 is spaced materially from the surface of the pads 29 on turrets 7, 7a so that the pads do not press the labels against the glue carrying surfaces of the drums 8.
  • the pads 29 limit the flapping of the labels but do not exert any mechanical pressure against the labels and do not come close enough to the gluing drum 8 to pick up any glue therefrom.
  • An optional feature is to provide air jet nozzles 28, 28a to blow a stream of air against the flying labels and hence assist in pressing them under light air pressure against the glued surface of the glue drum 8.
  • the light pressing thus achieved does not stick the labels tightly against the glue transfer surface of drum 3. Accordingly, the continued rotation of turrets 7, 7a easily peels the label from the drum at high speed and with little or no risk of tearing the label or dislodging it from the grasp of the gripper fingers 16.
  • the glue drum 8 is provided with recesses which align with the grippers and which receive the grippers out of contact with the glue surface. Means are also provided to prevent glue contamination of said recesses.
  • peripheral grooves 32 are provided in the drum 8, and these grooves align fingers l6 and the rotation of the drum 8 is such that these sockets 40 rotate in time with the grippers 16, thus to receive the fingers 16 as shown in FIGS. 5 and 6.
  • the gluing drum 8 have a uniform glue film thereon. Otherwise the light pressure of the flying label might not result in an even coating of glue on the label.
  • a doctor blade 33 is applied directly to the surface of drum 8 and the glue is injected onto .the drum surface through a nozzle 35 mounted at the head or top of the doctor blade 33.
  • Glue is supplied to the nozzle 35 through a hose 36 and there is an internal port 37 in nozzle 35 by which the glue is injected from nozzle 35 onto the surface of the drum 8.
  • the means to prevent glue contamination of the grooves comprises provision on the doctor blade 33 projecting tongues 34 which fit into the grooves 32 to exclude glue-from these grooves and prevent glue contamination of the gripping fingers 16.
  • such means comprises provision in each socket 40 of a plunger 9 mounted on a shaft 26 which has a roller 27 in contact with a cam 30. Springs (not shown) tend to retract the plungers 9 so that when the roller 27 is on a low lobe of cam 30 when the socket comes opposite the gripping fingers 16 the plungers 9 will withdraw into the socket 40, thus leaving ample room for the socket 40 to receive the gripping fingers as shown at the left in FIG. 6.
  • the roller 27 rides up on a high lobe of the cam 30 and projects its plunger 9 to be flush with the outer surface of the glue drum 8. Accordingly, the plungers block the sockets and prevent the doctor blade 33 from pushing glue into the socket 40. Ac cordingly, the plunger mechanism prevents glue contamination of the socket and precludes subsequent transfer of glue to the fingers .16.
  • the high speed method by which the aforedescribed apparatus applies a coating of glue to the label can be summarized as comprising the steps of gripping the leading edge of the label while leaving the trailing label portion free to fly, swinging the gripped label on an are past a gluing. surface to fly the trailing portion of the label against the gluing surface whereby the label will be urged under light pressure against the gluing surface and withdrawing the glued label from the gluing surface for subsequent application thereof to a container.
  • a gluing drum having a doctor blade in direct contact withthe gluing drum, recesses in said drum in alignment with the gripping fingers to receive said fingers below the drum surface as the gripping turret rotates past the drum, said gripping fingers gripping the leading edges of discrete pre-cut labels to leave trailing portions of the discrete pre-cut labels free to fly in unsupported relation as they are swept against the drum, and means to prevent glue contamination of said recesses.
  • doctor blade is provided at its top with a glue supply nozzle.
