Definitions

  • the feeder has plural arms, being a substantially star-shaped unit, each arm being provided with label singling and receiving surfaces containing controlled suction apertures for holding the labels.
  • a planetary or epicyclic gearing drives the star-shaped feeder so each label receiving surface passes along a cycloid path.
  • the invention relates to a label singling feeder for labelling machines where labels are extracted singly from a label container and delivered via a gumming drum to a label-applicator device.
  • a primary purpose of the invention is to improve the efficiency of the labelling machines, which operate with a gumming drum arranged before the labelfeeding mechanism, in such a way that, without any appreciably increased capital expenditure to be expended for the labelling machines, their output capacity can be considerably increased by improving the operating speed.
  • a primary object of the invention is to provide a feeder for labelling machines with which, usingthe simplest possible constructional means, it is possible to achieve a smooth singling extraction of the label from the label container so as to permit highest possible operating speeds, with a concurrent smooth transfer of the singled label to a suction transfer cylinder, interposed between the feeder and the gumming drum.
  • the labelling machine feeder is so constructed with arms arranged in star fashion and the end of each of its arms carrying the lable-receiving surfaces.
  • the feeder star unit is mounted on the crank pin of a crankshaft together with and connected fast for rotation with an externally toothed planet wheel arranged coaxially of the feeder star.
  • the planet gear wheel meshes with a fixed internally toothed sun wheel arranged concentrically of the crankshaft, the arrangement being such that the center line of suction apertures in each of the label-receiving surfaces at the ends of the feeder star arms describes a cycloid, of which an outer reversing point coincides with the label-transfer position between a feeder star arm and the label container arranged adjacent the periphery of the feeder star arm path while the transfer position between the feeder star arms and the periphery of a suction cylinder, located between the feeder star arm periphery path and the periphery of a cylindrical gumming drum, lies in the middle between the cycloid path reversing point and a second cycloid path reversing point which is adjacent to it.
  • the suction cylinder receives the labels from the label-supporting surface of the feeder star and advances them on to the periphery of the gumming 'drum.
  • the outer reversal points of the cycloid path are spaced apart by one-fifth of a revolution of the crankshaft and with one revolution of the latter, the feeder star carries out one-quarter of a revolution, and the transmission ratio between sun wheel and planet wheel amounts to 1.25 l.
  • the control of the suction apertures which are arranged on the feeder and which respectively secure and release the labels is effected in a manner which constructionally is simple by the fact that the planet wheel is formed with passage openings for the vacuum to be supplied to the suction apertures through a duct which is arranged axially parallel in the arm of and extends parallel to the axis of the feeder star and is in fluid communication with the suction apertures in the labelreceiving surfaces of the associated arm.
  • a packing surface which co-operates with a rotary slide valve, known per se, and urged under the action of a spring against the packing surface, the slide valve serving to selectively control the supply of vacuum to the suction apertures.

  • FIG. 1 DESCRIPTION Illustrated in FIG. 1 is the installation of a feeder 4 according to the invention, which always extracts one label from a label container 3 and transfers it to a suction transfer cylinder 5, from which it transfers to and is advanced by means of a gumming drum 6 provided with a coating of gum by a gumming arrangement 7 and with the coaction of a stripper device 13 in a manner known per se to the revolving belt 2 of a label-applying device which is provided with suction unions 55, the belt being constructed in known manner according to German Auslegeschrift 1,5 86,403 and running over a comparatively large drum 1 and a smaller drum 12, the labels taken over behind the stripper device 13 by the gumming drum 6 and held by suction effect on the belt 2 being fed to the articles, more especially the bottles 8, which are to be labelled and which are guided along on a rectilinear conveyor belt past the belt 2, after which they are gripped by the separating worm 9 arranged along the conveyor mechanism 10 on the outer edge thereof and
  • the labels are applied to the articles 8 while the latter are undergoing a rolling movement between the belt 2 and a counteracting surface 11 consisting of sponge rubber.
  • a labelling cylinder or the like constructed in the usual manner to co-operate with the feeder 4 and the gumming drum 6.
  • the labelling machine can also be equipped with two feeders 4, 4a in accordance with the invention, when the machine is, for example, concerned with the application of front and back labels, which feeders singly extract the labels 16, 16a, l6aa from the label containers 3 and 3a, respectively, and supply them by way of the suction cylinders 5 and 5a with the suction apertures 45 and 45a, respectively, successively to the circumference of the gumming drum 6, from which they are supplied by coaction of the stripper device 13, to the labelling cylinder 1' with the suction apertures 56.

  • FIG. 4 is a diagram which shows a plan view of the feeder in a diagrammatically simplified form, in which can be seen the rolling motion of the planet wheel 23 on the internal toothing of the sun wheel 22, in the same way as the cycloidal path described by the centers of the suction apertures 18 of the feeder 4 and having the outer reversing points 17a, 1712, which are loopshaped. Since the label-receiving surface 19 of each arm is set back by a distance a (FIG. 4), radially inwards relatively to the pitch circle of the sun wheel 22, as can also be seen in FIG.
  • the looped character of the reversing points 17a, 17b of the cycloid is established, with the effect that the uppermost label 16a to be separated from the label container 3 is extracted with a brief movement component of the labelreceiving surface 19, which surface is lying in the plane of this label 16a.
  • the label is shifted with the surface 19 it engages and is directed away from the other labels by the projection 24 on the end of the label container 3.
  • an extraction of the edge of the label 16a is efiected beneath the projection 24 before the loop at the outer reversal point 17a is left in the direction of the point of the arrow shown on the cycloid.
  • the path of the center points of the suction apertures 18 of the label-receiving surfaces 19 is along the cycloid path comprising the outer reversal points 17a 17e, in such a way that the label is transferred to the suction apertures 45 of the suction cylinder 5 exactly at the midpoint of the feeder surface path between the outer reversal points 17a and 17b, the maximum tangential speed occurring at this center point along the cycloidal path.
