Abstract
Abstract A longitudinal automatic sprayer for cleaning glass containers based on two parallel conveyor chains on which transverse beams carrying individual baskets are arranged perpendicularly to the direction of transport. At the beginning of the conveyor, the individual baskets are automatically filled with the unclean glass containers by a transfer device. A delivery device for automatically ejecting the containers is situated at the end of the conveyor. Spray nozzles for rinsing the glass containers are arranged above the conveyor. The individual baskets are checked for breakage by a mechanical scanning device underneath the conveyor chains. At the same time, the scanning device monitors the positioning of the individual baskets appropriate to the working cycle.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
135 words
A longitudinal automatic sprayer for cleaning glass containers for parenteral medicaments, comprising two parallel chains operating in cycles for conveying a row of transverse beams arranged perpendicularly to the direction of transport, said chains arranged to provide an upper and a lower conveyor run and said transverse beams carrying individual baskets, each basket for receiving one glass container, a transfer device at the upstream end of the upper conveyor run and a delivery device for the containers at the downstream end of the upper conveyor run, and spray nozzles for spraying the glass containers, wherein a mechanical scanning device for checking the baskets for the presence of glass bodies is arranged below the lower conveyor run, which scanning device at the same time controls the exact positioning of the baskets appropriate to the operating cycle.
Claim 2
Dependent Claim
135 words
A longitudinal automatic sprayer for cleaning glass containers for parenteral medicaments, comprising two parallel chains operating in cycles for conveying a row of transverse beams arranged perpendicularly to the direction of transport, said chains arranged to provide an upper and a lower conveyor run and said transverse beams carrying individual baskets, each basket for receiving one glass container, a transfer device at the upstream end of the upper conveyor run and a delivery device for the containers at the downstream end of the upper conveyor run, and spray nozzles for spraying the glass containers, wherein a mechanical scanning device for checking the baskets for the presence of glass bodies is arranged below the lower conveyor run, which scanning device at the same time controls the exact positioning of the baskets appropriate to the operating cycle.
Claim 3
Dependent Claim
37 words
An apparatus according to claim 1, wherein the scanning device comprises shaped elements which are movable into the baskets from below and in that the shape of the shaped elements conforms to the shape of the baskets.
Claim 4
Dependent Claim
27 words
An apparatus according to claim 1, wherein an ejector device for ejecting whole glass bodies or fragments from the baskets is arranged above the lower conveyor run.
Claim 5
Dependent Claim
23 words
