Installation for preparing batches of products, of the vial or bottle kind or the like

A conveying module for an installation for preparing batches of bottle-type products comprising:

• an upstream conveyor which supplies lines of products, and a conveying system located downstream comprising a downstream preparation conveyor topped with a cycling system with bars;
• a regulating unit for regulating the flow of products, placed between said upstream conveyor and said downstream conveyor, said regulating unit comprising passages for each line of products, each passage being delimited by walls which are guided on rails arranged transversely, and, in each passage, an endless belt type of conveying module and sets of mobile regulating fingers for controlling a speed at which said products advance in each passage, said sets of fingers being divided into two interleaved families controlled separately by drive elements to allow adjusting a distance separating said consecutive sets of fingers and to define the position of the products, a support which can be guided transversely being associated with each conveying module, wherein an endless belt of each conveying module extends all the way to an inlet of said downstream conveyor, and control means are provided for separately adjusting the speed of each of said two families of sets of regulating fingers and for adjusting the speed of said downstream conveyor, so as to achieve two ungrouping modes for said products,
• the conveying module comprising a long and slender frame supporting an endless belt in the form of a notched belt and a dead plate, said notched belt winding, at an end opposite said dead plate, over a roller in the form of a notched roller of small diameter, on the order of 10 to 15 mm.
