Device for conveying and checking containers, in particular preforms
First Claim
1. A device (1) for conveying and checking containers, in particular preforms, that comprises:
- an feeding and accumulation section (2) for the containers arriving from a container forming station, the feeding and accumulation section being loaded intermittently from the forming station;
a carrousel (3) which rotates continuously, located downstream of the feeding and accumulation section in the direction of container feed, to feed the containers through a sequence of checking stations (4);
connecting means located between the feeding and accumulation section and the carrousel and having means (8) for adjusting the alternate operation of the feeding and accumulation section relative to the continuous operation of the carousel, the connecting means comprise an endless chain (5) extending along a path defined by driving gear wheels (6), the path partially overlapping the circular trajectory of the carrousel;
characterized in that the adjusting means (8) comprise a first and a second driving gear wheels (9a, 9b) arranged along the path followed by the endless chain, located respectively on the delivery section of the feeding and accumulation section, the first and second driving gear wheels being mobile to compensate the variations in the length of the delivery and return sections.

Abstract
A device (1) for conveying and checking containers, in particular preforms, comprises an infeed and accumulation section (2) for containers arriving from a forming station and a carrousel (3) located downstream of the infeed and accumulation section (2) in the direction of feed of the containers, to feed the containers through a sequence of checking stations (4) disposed in the periphery of carrousel (3). The infeed section is intermittently supplied with containers by the forming station while the carrousel (3) turns continuously. An endless chain (5) extends along a path defined by driving gearwheels (6) which partially overlaps the infeed and accumulation section (2) and the circular trajectory of the carrousel (3). A first and second driving gearwheels (9a, 9b) positioned along the path followed by the endless chain (5) are mobile to compensate the variations in the length of a delivery section and a return section of the chain (5).
