Abstract: 1325647 Conveying and spacing articles SAINT-GOBAIN 6 April 1972 [7 April 1971] 15920/72 Headings B8A and B8S Apparatus for supplying a bottling station (not shown) with plastics bottles 2 comprises a spacing screw 4 located above a conveyer 1, and a vertical feed passage from which the bottles are allowed to fall one by one by a driven obturating member 8. The feed passage consists of guide rods 3 and includes photo-electric means 13, 14 for monitoring the bottles. A motor 10 which drives the obturating member 8 one rotation at a time is energized by a contactor (11, 12), Fig. 2 (not shown), when engaged by an apex of the thread of the screw 4. In operation, if the monitor means 13, 14 detects the presence of a bottle, e.g. 2b, in the feed passage 3, the obturating member 8 is actuated when the screw 4 is driven and the bottle 2b falls into a throat 6 of the screw. The form of the obturating member 8 ensures that the next adjacent bottle in the passage 3 is raised clear of the bottle, now 2c, engaged by the conveyer 1 and the screw 4. The movement of the obturating member 8 may be continuous during each revolution or the movement may be interrupted. The speed of the member 8 and of the motor 10 is variable to allow for bottles of different lengths. In place of the obturating member 8, a compressed air jet may be used for holding up the bottles in the passage 3. A pneumatic valve may replace the contactor (11, 12) and the photoelectric means 13, 14 may be replaced by an ultrasonic detector.
