Conveying unit with container accumulation
A conveying unit with accumulation of containers ( 6 ), especially of bottles, includes an accumulation table ( 2 ) equipped laterally with guide rails ( 12, 13 ) and composed of a juxtaposition of at least one feed conveyor ( 9 ) and one accumulation conveyor ( 10 ), the containers ( 6 ) being routed onto this table ( 2 ) at its upstream end via at least one feed transporter, and being discharged on the downstream end via at least one discharge transporter. The unit is characterized in that at least one of the guide rails ( 12, 13 ) is equipped with a transverse offset ( 12 a, 13 a ), composed of a segment of the guide rail ( 12, 13 ), with an amplitude ( 14 ) of between 0.2 and 0.8 times the diameter D of a container ( 6 ) and offset relative to the longitudinal axis ( 15 ) of the guide rail ( 12, 13 ) by a distance corresponding to the amplitude ( 14 ).
1. Conveying unit with accumulation of containers ( 6 ), especially of bottles, comprising an accumulation table ( 2 ) equipped laterally with guide rails ( 12 , 13 ) that keep the containers ( 6 ) on said table ( 2 ), and composed of a juxtaposition of at least one feed conveyor ( 9 ) and one accumulation conveyor ( 10 ), the containers ( 6 ) being routed onto this table ( 2 ) at its upstream end ( 3 ), especially via at least one feed transporter ( 4 ), and being discharged on the downstream end ( 5 ) via at least one discharge transporter ( 7 ), characterized in that at least one of the guide rails ( 12 , 13 ) is equipped with a transverse offset ( 12 a , 13 a ) composed of a segment of said guide rail ( 12 , 13 ), with an amplitude ( 14 ) of between 0.2 and 0.8 times the diameter D of a container ( 6 ) and offset relative to the longitudinal axis ( 15 ) of said guide rail ( 12 , 13 ) by a distance corresponding to said amplitude ( 14 ).
2. Conveying unit, according to claim 1 , wherein each guide rail ( 12 , 13 ) over its length comprises several transverse offsets ( 12 a , 13 a ) distributed over the entire length of the accumulation table ( 2 ).
3. Conveying unit according to claim 1 , wherein the transverse offsets ( 12 a , 13 a ) are equidistant relative to one another.
4. Conveying unit, according to claim 1 , wherein the transverse offsets ( 12 a , 13 a ) of the guide rails ( 12 , 13 ) are connected to said guide rails ( 12 , 13 ) by transition zones ( 16 , 17 ) with a slight incline, which are designed to ensure gentle, low-pressure transfer of containers ( 6 ) from the sides of the table ( 2 ) toward the center part of the latter and thus toward the feed conveyor ( 9 ).
5. Conveying unit, according to claim 4 , wherein the transition zones ( 16 , 17 ) have an angle of inclination ( 18 ) of less than 45° relative to the longitudinal axis ( 15 ) of the guide rails ( 12 , 13 ).
6. Conveying unit, according to claim 1 , wherein the transverse offsets ( 12 a , 13 a ) of the guide rails ( 12 , 13 ) are aligned crosswise to one another and in pairs have an identical transverse offset direction.
7. Conveying unit according to claim 2 , wherein the transverse offsets ( 12 a , 13 a ) are equidistant relative to one another.
8. Conveying unit, according to claim 2 , wherein the transverse offsets ( 12 a , 13 a ) of the guide rails ( 12 , 13 ) are connected to said guide rails ( 12 , 13 ) by transition zones ( 16 , 17 ) with a slight incline, which are designed to ensure gentle, low-pressure transfer of containers ( 6 ) from the sides of the table ( 2 ) toward the center part of the latter and thus toward the feed conveyor ( 9 ).
9. Conveying unit, according to claim 2 , wherein the transverse offsets ( 12 a , 13 a ) of the guide rails ( 12 , 13 ) are aligned crosswise to one another and in pairs have an identical transverse offset direction.
10. Conveying unit, according to claim 3 , wherein the transverse offsets ( 12 a , 13 a ) of the guide rails ( 12 , 13 ) are aligned crosswise to one another and in pairs have an identical transverse offset direction.
