Abstract

Apparatus for orienting and quickly directing into a plurality of container conveying channels a single file of containers, even irregularly shaped ones, comprising a feeding conveyor on which the single file of containers is caused to travel in a guided manner; a screw feeder for controlling the flow of the containers on the conveyor, and for suitably spacing them; a further conveyor with equispaced fingers for keeping a given number of containers in the spaced position; and deflecting blades for diverting the containers into sorting channels leading to the container conveying channels.

Claims

1. Apparatus for orienting and directing into a plurality of container conveying channels a single file of randomly shaped containers, comprising

(a) a first conveyor on which said single file of containers is caused to travel in a guided manner;

(b) means for controlling the flow of said containers on said first conveyor, and for suitably spacing them, comprising a screw means arranged partly over said first conveyor and continuously driven in rotation;

(c) a second conveyor provided with equi-spaced metallic fingers having one of their ends pivotably attached to said second conveyor and provided on their pivoted ends with an outwardly extending appendage, said fingers, when in working position, extending outwardly therefrom and transversely over said first conveyor, so as to longitudinally sweep it, and within which fingers at least one container is received from said screw means and is retained in the required spaced position, the operation of said second conveyor being synchronized with the operation of said screw means, and said second conveyor being arranged laterally and longitudinally of said first conveyor, with at least its active branch in parallel relation thereto, and running in the same direction as said first conveyor; and

(d) deflecting blades for diverting said containers into sorting channels leading to container conveying channels, a given number of containers being led in-phase by said second conveyor into contact with said deflecting blades, said blades being, upon control, simultaneously shifted into their working position, each before a respective one of said containers so as to direct a said container into the corresponding sorting channel, and then being returned to their rest positions for the next deflecting cycle.

2. Apparatus according to claim 1, wherein said screw means consists of an Archimedean screw feeder.

3. The apparatus according to claim 1, wherein said fingers are urged by spring means into their working position transversely over said first conveyor, and are arranged to swing backwards, upon engagement with a container jammed in the feeding line, with their said appendages contacting a component of an electric circuit fed by a low voltage source, so as to determine its closure, said component consisting of a metallic rod arranged longitudinally of and parallel with said second conveyor and which with the interposition of electric insulation means is mounted on its own support, and is connected to one end of said circuit, which has its other end connected to the frame of said apparatus, said electric circuit piloting a safety unit, so that its closure will cause stoppage of said apparatus.

4. Apparatus according to claim 3, wherein said closure of said safety unit also actuates an alarm signal upon jamming of a container in said feeding line.

5. Apparatus according to claim 1, wherein one of said sorting channels is arranged in line with said first conveyor so that it receives the containers directly from the latter, said deflecting blades being cyclically shifted into their working positions only after at least one container has passed the zone controlled by said blades.
