Abstract
Abstract An apparatus for labelling objects, such as bottles, jars, etc., the apparatus including a conveyor belt serving to supply and carry away the objects, a label store, from which the labels are passed onto a constantly revolving label distributor arranged adjoining the conveyor belt and on to which the forwardly moved bottles are brought. The label distributor cooperates with a counter-support arrangement for the bottles which faces the label distributor parallel and adjacent to the conveyor belt. The label distributor is constructed as an endless, yieldable, internally toothed belt normal to and having a bottle engaging stretch which is parallel to the conveyor belt. The distributor belt is maintained on rotary guide members, such as toothed cylinders or rolls, rotatable about shafts perpendicular to the supporting surface of the conveyor belt being driven by at least one of the guide members with the speed of travel of the conveyor belt. Openings for gripping the labels are disposed on the label distributor and a subatmospheric air pressure is adapted to be admitted to the openings by means of a suction air source through a rotary guide member via a fixed rotary slide valve.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
298 words
Apparatus for labelling objects, such as bottles, used in combination with a conveyor belt which supplies and carries away the objects comprising a label store, means to pass labels from the store to a distributor, a label distributor arranged adjacent one edge of the conveyor belt and a counter-support arrangement for the objects facing the label distributor and adjacent the other edge of the conveyor belt, said label distributor comprising an endless, yieldable belt which has a stretch parallel to the conveyor belt, guide members mounting said distributor belt and rotatable about axes perpendicular to the supporting surface of the conveyor belt, the distributor belt being driven by at least one of said guide members with the speed of travel of the conveyor belt, the distributor belt having at least one group of aligned openings subject to suction for gripping the labels, and means whereby a sub-atmospheric air pressure is adapted to be admitted from a suction air source to the said openings through a fixed rotary slide valve, the improvement comprising: fluid communication passages from the front surface to the rear surface of said distributor belt; at least one of said guide members being a rotary cylinder, on the external circumference of which open at least one group of substantially radially directed bores having associated means which can be brought into communication with the suction air source by way of the rotary slide valve as long as said cylinder bores are in communication with fluid communication passages arranged in the distributor belt and during the passage of the distributor belt past a station where the distributor picks up a label until that part of the belt travel where the distributor carried label reaches an object which is on the conveyor belt and in position to be labelled.

298 words
Apparatus for labelling objects, such as bottles, used in combination with a conveyor belt which supplies and carries away the objects comprising a label store, means to pass labels from the store to a distributor, a label distributor arranged adjacent one edge of the conveyor belt and a counter-support arrangement for the objects facing the label distributor and adjacent the other edge of the conveyor belt, said label distributor comprising an endless, yieldable belt which has a stretch parallel to the conveyor belt, guide members mounting said distributor belt and rotatable about axes perpendicular to the supporting surface of the conveyor belt, the distributor belt being driven by at least one of said guide members with the speed of travel of the conveyor belt, the distributor belt having at least one group of aligned openings subject to suction for gripping the labels, and means whereby a sub-atmospheric air pressure is adapted to be admitted from a suction air source to the said openings through a fixed rotary slide valve, the improvement comprising: fluid communication passages from the front surface to the rear surface of said distributor belt; at least one of said guide members being a rotary cylinder, on the external circumference of which open at least one group of substantially radially directed bores having associated means which can be brought into communication with the suction air source by way of the rotary slide valve as long as said cylinder bores are in communication with fluid communication passages arranged in the distributor belt and during the passage of the distributor belt past a station where the distributor picks up a label until that part of the belt travel where the distributor carried label reaches an object which is on the conveyor belt and in position to be labelled.
Claim 3
Dependent Claim
28 words
Apparatus according to claim 1, wherein the guide cylinder is externally toothed and the distributor belt is toothed on the inner surface to mate with said cylinder teeth.
Claim 4
Dependent Claim
22 words
Apparatus according to claim 2, wherein the guide cylinder bores open in the head end surfaces of selected teeth of said cylinder.
Claim 5
Dependent Claim
20 words
Apparatus according to claim 1, wherein said cylinder is formed with narrow marginal end flanges projecting beyond its circumferential surface.
Claim 6
Dependent Claim
65 words
Apparatus according to claim 1, wherein the width of the distributor belt is greater than the height of the label to be applied to the object so that marginal strips of the distributor belt will not be covered by the label and that said strips are disposed above and below label-receiving surfaces of the belt which are arranged symmetrically in height on its outer surface.
