My invention relates to labeling round or cylindrical bodies such as bottles.

In machines for this P pose it is known to use label carriers" which are provided with ,5 gluing members or strips and to move the label carriers or feeders successively in a circular path past a gluing device which dresses the gluing members with glue and pasta label case from which a label is drawn, and then to move the label in carrier to the labeling point.

This known arrangement has the disadvantage that the label is not always satisfactorily glued,

. because for instance very strong labels do not get into contact with the gluing strip on their 15 whole surface. Also, the glue sometimes has such a consistence that the bulk of the glue stays at the gluing strips so that even .in the case of the label resting fully on the strips it is only partly glued.- Another disadvantage of the known de- 20 vices consists in the fact that if for any reason a gapoccu'rs in the bottles being fed to the labeling place, while thelabel carrier can be prevented from picking up a label, the gluing strips cannot be prevented from being dressed with glue. If

several bottles fall ofi successively, the deposit of glue on the gluing strips becomes so thick that a label which is put on the strips when the normal working order sets in again, gets an excessive amount of glue so that the bottle issmeared.

The present invention relates to a labeling device for cylindrical bodies such as bottles which are continuously moved in a straight line in upright position, in which the label carrier is also. rotated in a circular path around a vertical axis 35 and. is moved past a label pile and a gluing device. However, an important distinction from the known machines of this kind resides in the fact that the label carrier or feeder is not provided with gluing strips but possesses'faces for receiv- 40 ing the label which are always dry, the label being picked up from the label'pile in dry condition by means of grippers, suction nozzles or other means; the label carrier is then moved past a gluing roller or cylinder which according to the invention rotates around a vertical axis, rolls over the labeland causes a. satisfactory gluing of the label. The transfer of the glued label to the cylindrical body is then efiected in known manner. My invention will be better understood from the following detailed description in connection with the accompanying drawings showing schematically andby way of example one embodiment 55 of the invention, viz:

devices for Fig. 1 is a plan view of the device in one working position;

Fig. 2 is a plan view of the same device in another working position;

Fig. 3 is a perspective view partly in section of the cylinder and the devices that operate it;

Fig. 4 is an elevation showing the counterholdingstrip and associated mechanism Fig. 5 is a detailed perspective viewof the bottleoperated control mechanism. 1

Referring now to the drawings, l is a vertical cylinder which rotates around the axis 2 and bears at its circumference for example five label carriers 3. The distance between the single label carriers is'the same as that between the bottles 5 whichstand on the continuously moving conveyor belt or device 4. The conveyor belt 4 and the circumference of the cylinder I have the same travelling speed. Besidethecylinder I is a label case or magazine 6 which can be moved in radial 6 direction towards the cylinder I so that it is possible to move it tightly to a label carrier 3 if required, as-shown in Fig. 1, or keep it at a certain distance from the label carrier, as indicated in Fig. '2. Behind the label case in the moving direction of the cylinder l is the glue container 1 which is also movable in radial direction with the gluing cylinder 9 which rotates continuously around its vertical axle 8. The label carriers .3 are provided with means for picking upf the dry'labels from the label pile, in the manner known per se. This picking up may be effected for instance in such manner that the faces of the label carriers 3 are provided with bores which are connected'to a suction or vacuum pipe. This pipe is controlled in the manner known per se in such a way that the suction effect is started when the label carrier approaches the label pile, and ceases as the label carrier comes into contact with the bottle 5 and transfers I 40 the label to it.

The cam 21 actuates the piston of an air pump 28 which is connected by a tube 29 with the hollow shaft or pipe! which is stationary. The carriers 3 for the labels and the sleeve carrying the member I are provided with air holes which are alternately covered'so that the passage of air is partly interrupted while'the label is being transferred to the bottle on the conveyor. Instead of sucking devices I may alsov use grippers of the kind used in printing machines which in 'myldevice'work in such manner that they grip the dry label at one edge thereof, and

. hold it until it is transferred to the bottle.

During the transfer of the label from the label carrier to the bottle pressure is exerted. to the latter in the direction perpendicularly to the longitudinal axis of the conveyor belt 4 or in radial direction of the cylinder I. In order to prevent the bottle from being displaced thereby, I provide a counterholding strip Ill at the opposite side of the bottle conveyor belt which is guided to carry out a straight to and from movement parallel to the conveyor belt 4. In the moment when a label is transferred to the bottle, the strip l0 follows the movement of the continuously moved conveyor belt. Accordingly there is no relative movement between the strip l0 and the bottle 5 and thus no rotation of the latter will be caused. When the pressure is no more exerted to the bottle, the strip l0 moves back to its initial position. The same result is obtained according to Fig. 2 by arranging an endless belt H parallel to the conveyor belt 4 and moving with the same travelling speed as the belt 4. The belt ll runs over vertical rollers I2 and is equipped with bottle holders l3 by which the accurate spacing of the bottles on the belt 4 is ensured.

Now, if for any reason a gap results in the row of bottles which are continuously moved to the labeling place with a uniform spacing, according to the invention no label will be picked up from the label pile and the gluing cylinder 9 will not come into contact with the label carrier.

This is effected by means of a device which coacts with a feeling member arranged at the bottle conveyor belt in such manner that the label case and the gluing device cannot touch the label carrier when a bottle falls ofi. One embodiment of such a device has been shown in the drawings by way of example.

Near the bottle conveyor belt 4 is a feeling lever 15 which is pivotally mounted at I4 and under action of a spring which is not shown in the drawings tends to move in the direction of the arrow shown in Fig. 1 and so to get into the position shown in Fig. 2. Rigidly connected to this feeling lever I5 is a lever l6 which in turn by a rod I1 is coupled to a lever having two arms I8, l9 and being pivotally mounted at 20; the arm l9 bears a barbed or ratchet hook 2| which engages with the stop 22 if the feeling lever l5 takes up the position as per Fig. 2, i. e., if a bottle has fallen off. The hook 2! then makes it impossible for the label case to move towards the label carrier. On the stop 22 res'ts moreover an arm 24 which is pivotally mounted at 23, under action of a spring which is not shown in the .drawings. This arm 24 is rigidly connected with another arm 25 which is bent at right angles at one end. This arm in 'case of the blocked position of the hook 2| engages with a stop 26 of the glue container :1, and thereby makes it impossible for the glue container 1 to move towards the label carrier if the latter has not picked up a label from the label case. Accordingly it is rendered impossible for the glue cylinder 8 to deposit glue directly on the label carrier.

When transferring the glued label to it is only temporarily aflixed thereto and devices of known construction have to be provided behind the labeling place for pressing the label tight on the bottle. Such a device for pressing on the label is schematically shown at 21 in Fig. 1.
