Definitions

  • a machine for labeling objects, particularly containers, and espcially bottles wherein an endless beltlike element travels around two spaced guide rolls and has a run parallel with a conveyor transporting the objects to be labeled to, through, and from the machine.
  • the element has a cavity alternatingly connected to a source of subatmospheric pressure air and to a source of superatmospheric pressure air. Passages. are connected to said cavity and terminate in openings in the outside surface of said beltlike element for alternatingly producing suction thereat for holding labels on said outside surface and air pressure for blowing the labels onto the objects to be labeled.
  • a counteracting device is placed alongside the conveyor and opposite said run of said beltlike element for holding the objects on said run while the labels are applied.
  • the present invention relates to a machine for labeling objects, particularly containers and especially bottles.
  • Such machines so far, operate with a labeling cylinder on whose circumference label receiving surfaces are provided which are made of soft-elastic material, for example rubber, having suction openings for holding the labels to the surfaces.
  • the labels are taken, by means of a placing device which usually consists of a suction roll, from a label supply container arranged close to the circumference of the labeling cylinder and are conveyed to the label receiving surfaces of the labeling cylinder.
  • the objects to be labeled are moved by a conveyor belt tangentially to the labeling cylinder.
  • a stationary or movable counterholding device with an elastic active surface, preferably made of sponge rubber, is arranged opposite the labeling cylinder alongside the conveyor belt.
  • the trouble-free effective operating speed of the conventional labeling machines is limited because the duration of the pressure applying the labels to the objects, which is also important for assuring the stability of the objects on the conveyor belt, is very short because it is limited to the moment when the active label receiving surface passes the point where said surface moves parallel with the conveyor belt.
  • the aforesaid and other objects are obtained, according to the invention, by providing an endless, flexible band-, strand, beltor chain-like element which travels 3,547,736 Patented Dec. 15, 1970 around at least two spaced, substantially cylindrical guide elements rotating around parallel axes, at least one of the guide elements being positively driven.
  • the beltlike element contains at least one hollow space which is connected by a flexible conduit to a conventional distributing valve placed in the space surrounded by the beltlike element and rotating sychronously therewith, for alternatingly connecting said hollow space to a source of air of subatmospheric pressure and of superatmospheric pressure.
  • the aforesaid hollow space is connected to at least one opening in the outside surface of the beltlike element.
  • a counteracting device is placed opposite a first run of said beltlike element parallel therewith and alongside of a conventional conveyor belt for supplying and removing the objects to be labeled which belt travels alongside said run of the beltlike element at a speed equal to the traveling speed of the latter, a gumming device, a label supply container and a label applying apparatus being arranged alongside said beltlike element, particularly alongside the second run of said beltlike element.
  • the beltlike element comprises a first rubber belt vulcanized to a second, toothed rubber belt, the aforesaid hollow space being formed by a piece of rubber hose vulcanized into the first belt, the aforesaid opening being at the end of a conduit, terminating laterally in said hose.
  • Connection of said hollow space to said valve can be i simply effected by projecting a portion of the aforesaid rubber hose from the first rubber belt and connecting a suitable conduit to said projecting portion.
  • This conduit is preferably formed by a thin walled rubber hose having reinforcing means placed therein to prevent compression of the hose by the exterior air pressure.
  • an additional hollow space may be provided in the element extending longitudinally thereof, communicating with the first hollow space and having conduits laterally connected thereto and terminating in the outside surface of the element.
  • the counteracting device with a rigid plate whose position normal to the plane of the plate is adjustable and whose active surface is preferably provided with a sponge rubber covering.
  • the counteracting device for labeling bottles having two parallel opposite plane surfaces it may be of advantage to provide the counteracting device in the conventional manner with an elastic belt preferably made of rubber and traveling around at least two guide rolls.
  • This belt may be driven at the speed of the conveyor belt or may be arranged to move freely.
  • a particularly compact arrangement of the apparatus according to the invention is obtained by placing the label supply container next to the second run of the beltlike element with the longitudinal axis of the container parallel with said second run.
  • the counteracting device may be in the form of a second beltlike element.
  • the beltlike element in the form of a chain carrying segments, one for each object to be labeled, the segments being provided with rubber coverings having a hollow space and a conduit connected thereto and an opening as described before.

  • a rigid, straight roll-on surface provided with a soft-elastic covering preferably made of sponge rubber is placed immediately downstream of the run of the belt which run is alongside the conveyor belt and in line therewith, the roll-on surface having a front edge tonguelike reaching around the belt or the belts.
  • the application, particularly of the front labels, is facilitated if the outside of the beltlike element is provided with preferably rectangular recesses suitable to receive a portion of the circumference of the objects to be labeled.
  • Adaptability of the apparatus to solve various labeling problems can be improved by providing, on the machine frame, an adjustable belt tightener for the belt of the counteracting device.
