Apparatus and method for gripping, separation, transport and / or deposit of closed and / or unsealed petri dishes

摘要

The invention relates to a device for gripping, separation, transport and / or deposit of petri dishes and a method for operating same. The device has a travelling unit, which is of an associated electronic control unit is controlled and at least one degree of freedom. On / in the travelling unit is a gripper is arranged, which has two horizontally aligned frame elements, the petri dishes of different diameter along its circumference and the at least partially surround are connected to a drive, which is connected with the electronic control unit, so that the frame elements horizontally movable towards and away from one another are. In this case, the distance of the frame elements can be adjusted relative to each other by way of the electronic control unit. At each frame members is in each case a grip element to the gripping and holding of petri dishes between the gripping elements of the two frame elements, whereby the gripping elements with vertically movably mounted and fastened to the frame elements and gripping elements in a spacecraft return springs are somewhat more reproducible. On at least one gripping element is a component is arranged, which together with the gripping element is moved and by means of an associated sensor for detecting of the component, which is arranged on a frame element and to the electronic control unit is connected, a detection of the position of the component is. At each frame element, which can be extended units are also arranged, which is connected with the electronic control unit and are controlled by it, and which, by means of lifting magnet, with springs for returning into a starting position, an ejection plate is moved vertically downwardly moving, wherein the ejection of plates in the case of the encompassing a petri dish lie at the bottom of the respective petri dish.
