Positioning device for a sample distribution apparatus, sample distribution apparatus with positioning device and method for positioning

摘要

The invention relates to a positioning device for a sample distribution apparatus, such as a pipetting apparatus, providing a first part, at which a sample transport device can be arranged, a second part, at which a sample holder can be arranged, wherein the first part and the second part are arranged moveable in relation to each other between a first position and an adjusted target position of the first and second part for performing a positioning motion, such that a sample can be conveyed towards the sample holder by the positioning motion. The automated change of the target position assists for achieving an error-free positioning and sample distribution. A corresponding method for the automatical change of a position of a first part relative to a second part using the positioning device, is also claimed.

主权项

1. Positioning device (1; 1′) for a sample distribution apparatus (100; 100′, 200) providing:
a first part (10; 10′), configured such that a sample transport device (102) is arranged at the first part, a second part (20; 20′), configured such that a sample holder (103; 103′) is arranged at the second part, wherein the first part and the second part are arranged moveable relative to each other between a first position and an adjusted target position of the first and the second part for performing a positioning motion, wherein an actuation motion is provided, which serves the conveyance of the sample, a positioning auxiliary device (30; 30′), which provides at least one means for limiting (40; 40′) of the relative mobility of the first and the second part in the adjusted target position, which provides at least one means for adjustment (50; 50′) of the n-th target position from a plurality of N predetermined target positions as the adjusted target position, which provides at least one means for changing (60; 60′) of the adjusted target position from the n-th target position to a (n+1)-th target position, and which provides at least one first means for coupling (70; 70′) of the actuation motion and the at least one means for changing such that the change from said n-th target position to said (n+1)-th target position can be effected by the actuation motion via the at least one means for coupling, wherein the positioning device is configured such that the n-th target position is adjusted, before the positioning motion of the first and the second part into the n-th target position is finished.
