Freeze drying installation
View Patent ↗The invention relates to a freeze drying installation ( 8 ), including a device ( 9 ) for moving containers ( 10 ) such as vials or the like along a surface supporting the containers to load and/or unload the containers into a freeze dryer processing chamber ( 200 ), wherein the device comprises two articulated arms, wherein each articulated arm comprises a first rigid upper arm and a first rigid lower arm connected to each other by a first rotary joint, wherein the ends of the two articulated arms are connected to a rigid transfer bar by articulated joints, which are spaced apart from each other when seen along an extension axis of the transfer bar, and wherein the two articulated arms are driven by at least one driving unit in a synchronised manner such that the transfer bar is movable along a loading and/or unloading axis to load or unload containers into or from the freeze dryer processing chamber.
1 . A freeze drying installation ( 8 ), including a device ( 9 ) for moving containers ( 10 ) along a surface ( 63 ) supporting the containers ( 10 ) to load and/or unload the containers ( 10 ) into a freeze dryer processing chamber ( 200 ), wherein the device ( 9 ) comprises a first articulated arm ( 102 ) and a second articulated arm ( 103 ), wherein the first articulated arm ( 102 ) comprises a first rigid upper arm ( 23 ) and a first rigid lower arm ( 21 ) connected to each other by a first rotary joint ( 22 ) and the second articulated arm ( 103 ) comprises a second rigid upper arm ( 46 ) and a second rigid lower arm ( 41 ) connected to each other by a second rotary joint ( 45 ), wherein an end of the first articulated arm ( 102 ) and an end of the second articulated arm ( 103 ) are connected to a rigid transfer bar ( 60 ) by a first articulated joint ( 20 ) and a second articulated joint ( 40 ), which are spaced apart from each other when seen along an extension axis ( 61 ) of the transfer bar ( 60 ), and wherein the first articulated arm ( 102 ) is arranged on a supporting platform ( 110 ) at a first connection point and the second articulated arm ( 103 ) is arranged on the supporting platform ( 110 ) at a second connection point, wherein the first articulated arm ( 102 ) and the second articulated arm ( 103 ) are driven by at least one driving unit ( 70 ) in a synchronised manner such that the transfer bar ( 60 ) is movable along a loading and/or unloading axis ( 62 ) to load or unload containers ( 10 ) into or from the freeze dryer processing chamber ( 200 ).
2 . The freeze drying installation ( 8 ) according to claim 1 , wherein the loading and/or unloading axis ( 62 ) is perpendicular to the extension axis ( 61 ) of the transfer bar ( 60 ).
3 . The freeze drying installation ( 8 ) according to claim 1 , wherein the first and second articulated arms ( 102 , 103 ) move in opposite directions of rotation.
4 . The freeze drying installation ( 8 ) according to claim 1 , wherein, in a storage position of the first and second articulated arms ( 102 , 103 ), the first rigid upper arm ( 46 , 23 ) and the first rigid lower arm ( 41 , 21 ) of each of the articulated arms ( 102 , 103 ) are arranged in parallel or essentially in parallel with the extension axis ( 61 ) of the transfer bar ( 60 ).
5 . The freeze drying installation ( 8 ) according to claim 1 , wherein at least one of the articulated arms ( 102 , 103 ) comprises a second upper (47) arm and a second lower arm ( 43 ) connected to each other by a second rotary joint ( 44 ).
6 . The freeze drying installation ( 8 ) according to claim 5 , wherein the second upper arm ( 47 ) is driven by the at least one driving unit ( 70 ) in such a manner that the second upper arm ( 47 ) and the first upper arm ( 46 ) of the same articulated arm ( 102 , 103 ) move in opposite directions of rotation.
7 . The freeze drying installation ( 8 ) according to claim 6 , wherein the first upper arm ( 46 ) is driven around a first axis ( 49 ) and the second upper arm is driven around a second axis ( 48 ) and wherein the first axis ( 49 ) and the second axis ( 48 ) are concentric to each other.
8 . The freeze drying installation ( 8 ) according to claim 1 , wherein the articulated arms ( 102 , 103 ) are arranged on a first side of the supporting platform ( 110 ) and the at least one driving unit ( 70 ) is arranged on a second side of the supporting platform ( 110 ) which is opposite the first side.
9 . The freeze drying installation ( 8 ) according to claim 8 , wherein the first side is part of a classified process area and the second side is outside of the classified process area.
10 . The freeze drying installation ( 8 ) according to claim 1 , wherein the containers ( 10 ) are vials.
11 . The freeze drying installation ( 8 ) according to claim 1 , wherein the driving unit ( 70 ) moves a first shaft ( 72 ) that is attached to a pulley ( 77 ) and a gear wheel ( 75 ), wherein the pulley ( 77 ) transfers a rotation of the driving unit ( 70 ) to the first articulated arm ( 102 ) via a second shaft ( 49 ).
12 . The freeze drying installation ( 8 ) according to claim 11 , wherein the second shaft ( 49 ) is connected to a second pulley ( 53 ) that rotates with the second shaft ( 49 ), wherein the second pulley ( 53 ) is connected to a third pulley ( 26 ), wherein the third pulley ( 26 ) transfers rotation from the driving unit ( 70 ) to the second articulated arm ( 103 ) via a third shaft ( 24 ).
