Definitions

  • Prior art labeling apparatus typically includes a transfer roller for transferring labels from the label magazine to the label turret.
  • the transfer roller desirably has the same surface speed as the peripheral speed of the label turret when a label is transferred from the transfer roller to the turret to thus provide a smooth transfer of the label.
  • Various arrangements are also employed to prevent the transfer of a label to the suction roller when a bottle is missing in the feed path to the label turret.
  • a glued transfer roller is employed and the label magazine is shuttled toward and away from the transfer roller by a rotating crank. If a bottle is missing, the crank is turned out of its working position by a magnet which is actuated by bottle switches located in the bottle feed path.
  • the speed of the transfer roller and thus the speed of the label turret is limited by the speed at which the label magazine can be shuttled back and forth and the speed at which the motion of the label magazine can be stopped and started.
  • a second type of prior art label feed device uses a suction roller to transfer labels from the label magazine to the label turret. When a bottle is missing, the suction is released and a label is not picked up from the magazine. This feed device has proved unsatisfactory because of maintenance problems with the control for switching on and off of the suction. Furthermore, since the labels always contact the suction roller, the labels sometimes fall from the magazine when the suction is turned off.
  • the invention provides a label feed device in which a transfer roller and label magazine are supported in unitary assembly on the same housing and driven by the same input shaft.
  • the compact size of the assembly permits as many as four of the devices to be arranged around a label turret, whereas, only as many as three prior art label feed devices could be arranged around a label turret.
  • the label feed device of the invention eliminates the problems associated with swiftly accelerating and decelerating the masses of the transfer roller and label magazine by utilizing a transfer roller which is rotated at a variable rate during each revolution about a fixed or stationary axis.
  • the label magazine and a label magazine support are orbited in a tangential path toward the transfer roller and then away from the transfer roller on an offset path to clear the transfer roller by an arrangement which includes two spaced horizontal posts on the label magazine support which are slidably received in spaced bores in a guide.
  • the rear ends of the posts are interconnected by a plate which is pivotably connected to the housing by a link and a vertical post.
  • the guide is supported on the housing and has an aperture which receives a crank driven by The input shaft.
  • the invention also provides an arrangement to interrupt movement of the label magazine toward the transfer roller to prevent transfer of a label to the transfer roller if a container is absent in the feed path to the label turret.
  • a rotary solenoid is energized by a limit switch to move a blocking arm in a position to limit forward movement of the magazine support and prevent contact of the labels with the transfer roller.
  • the label feed apparatus of the invention provides a compact, stationary assembly in which only the label magazine and magazine support are oscillated.
  • the blocking arrangement is quickly actuated to interrupt forward travel of The magazine when a bottle is missing to thus afford a high speed labeling operation.
  • FIG. 1 is a diagrammatic side view in fragmentary section of label feed apparatus in accordance with the invention.
  • FIG. 2 is a diagrammatic plan view of the apparatus shown in FIG. 1.
  • FIG. 3 is an enlarged schematic plan view showing the position of the label magazine and the suction roller at the moment the suction nozzle contacts and picks up the label.
  • FIG. 4 is a schematic view similar to FIG. 3 showing the label in the course of being withdrawn from the magazine for delivery to the label turret.
  • FIG. 5 is a schematic view similar to FIG. 3 showing the transfer of a label to the label turret.
  • FIG. 6 is a diagrammatic view showing the elliptical path of the labels in the label magazine.
  • FIG. 7 is an enlarged fragmentary end perspective view of the apparatus shown in FIG. 1.
  • FIG. 1 discloses a label turret l which has a plurality of circumferentially arranged suction nozzles 2 adapted to carry labels to a bottle onrolling station (not shown).
  • the label feed apparatus of the invention includes a transfer roller 3.
  • the transfer roller is provided with a plurality of suction nozzles (not shown).
  • the transfer roller can be a glued roller.
  • the suction roller 3 is fixedly secured to a shaft 28 which is journaled for rotation about a stationary axis in an aperture in a boss 28A, on a housing 15 which is supported on a machine table 27.
  • the means includes a drive shaft or input shaft 23 rotatably supported on the housing 15 and offset from the shaft 28.
  • the means also includes a drive sprocket 22 which is connectable to a motor (not shown) and a drive disc or plate 10 provided with an upwardly open slot 13A, which receives a follower or crank roller 12 which is rotatably mounted on a crank 14, which is fixedly secured to the shaft 28.
  • the shafts 28 and 23 and the crank 14 and plate 10 are arranged so that the roller 3 has a peripheral or surface speed approximating the surface speed of the label turret 1 when a label 4 is transferred from the suction roller 3 to the label turret 1 and a slower surface speed as a label 4 is picked up by the suction roller 3 as hereinafter described.
  • Labels 4 are in a stack 4A in a label magazine 5.
  • the magazine 5 is supported by a label magazine support 9 which includes two spaced vertical posts 9A interconnected by upper and lower cross-plates 10A and 11A.
  • the invention also provides means for moving the label magazine 5 in an orbital or generally elliptical path toward and away from the suction roller 3 in timed sequence with rotation of the suction roller 3, so that the exposed label 4 in the magazine S'is in a position touching the suction roller 3 as the suction roller 3 is rotating at its lowest peripheral speed.
  • the means comprises a shaft 20 (FIG. 1) rotatably supported in the housing 15 and a gear 17 which is in mesh with a gear 11 fixed to the shaft 23.

  • the posts 12A are slidably and reciprocally received in the bores 6A and are interconnected at their ends by a plate 26.
  • the posts 12A are provided with springs or washers 19 and stops 18 which are threaded on posts 12A.
  • Springs 7 are arranged around the posts 12A and located between bosses 24A and stops 8 on the posts 12A.
  • Means are also provided for pivotally connecting the posts 12A to the housing 15.
  • the means comprises a rod 29 (FIG. 7) which is pivotally connected to a link or block 16.
  • the block 16 is fixedly connected to a vertical shaft 30 which is rotatably supported in an aperture in the housing 15.
  • the crank 21 causes an orbital movement of the guide 6.
  • the motion of the guide is transmitted to the label magazine 5 through the posts 12A and the springs 7.
  • the articulated or pivoted connection of the posts 12A to the housing through rod 29 and the link 16 causes the label magazine 5 to orbit on an oblong circular or generally elliptical path 15A, as shown in FIG. 6.
  • the invention also provides means for limiting the movement of the label magazine 5 toward the suction roller 3 when the bottle train is interrupted by a missing bottle in the feed path to the onrolling station.
  • the means comprises a rotary solenoid (FIG. 7) which has an armature 25A connected to a blocking arm 24.
  • An arm 31 is fixed to shaft and provided with an extension or a buffer 32.

  • FIGS. 3, 4 and 5 show three different positions of the label magazine 5 during the transfer sequence of a label from the magazine 5 to the label turret 1.
  • the surface of the suction roller is contacting the outermost label in the magazine 5 at a point intermediate the ends of the label.
  • the magazine 5 is at the closest point to the roller 3 in its elliptical path as indicated by the dot designated 40 in FIG. 6.
  • the roller 12 is also at its innermost radial position in the slot to provide a low speed for the suction roller 3 which is also at a speed lower than the tangential speed of the label in the label magazine.
  • FIG. 4 a label 4 has been withdrawn from the label magazine 5 and the crank 21 has rotated from the position in FIG. 3 pivoting the link 16 through a small arc.
  • the plate 10 and slot 13A have moved 90 from the FIG. 3 position.
