Abstract

Abstract A mechanism for transferring objects from one position to another position in another turntable. A slide is mounted to be slidable on a guide on the turntable. The slide comprises a slot which extends transversely of the guide and in which a drive member is accommodated which is connected to one end of a first arm, the other end of which is pivotably connected to a second arm which is journalled in the turntable by way of a shaft and which is coupled to a drive. Around this shaft a wheel is rigidly arranged. This wheel is coupled to a further wheel, the center of which is formed by the pivot of the first and the second arm. This further wheel is rigidly connected to the first arm. The arrangement is such that, when the shaft is driven, the drive member follows an elliptical path. On the slide there is provided a gripping member for gripping and releasing the objects to be transferred.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 173 words
A mechanism for transferring objects, notably samples, from one position to another, characterized in that the mechanism comprises a turntable around which a plurality of positions may be present, a slide being slidably arranged on a guide on the turntable, said slide comprising a slot which extends transversely of the guide and in which a drive member (pin or roller) is accommodated which is secured to one end of a first arm, the other end of which is pivotably connected to a second arm which is journalled in the turntable by way of a shaft and which is coupled to a drive, a wheel being rigidly arranged around this shaft, said wheel being coupled to a further wheel whose centre is formed by the pivot of the first and the second arm and which is rigidly connected to the first arm, the arrangement being such that, when the shaft is driven, the drive member follows an elliptical path, the slide accommodating a gripping member for gripping and releasing the objects to be transferred.
Claim 2
Dependent Claim 173 words
A mechanism for transferring objects, notably samples, from one position to another, characterized in that the mechanism comprises a turntable around which a plurality of positions may be present, a slide being slidably arranged on a guide on the turntable, said slide comprising a slot which extends transversely of the guide and in which a drive member (pin or roller) is accommodated which is secured to one end of a first arm, the other end of which is pivotably connected to a second arm which is journalled in the turntable by way of a shaft and which is coupled to a drive, a wheel being rigidly arranged around this shaft, said wheel being coupled to a further wheel whose centre is formed by the pivot of the first and the second arm and which is rigidly connected to the first arm, the arrangement being such that, when the shaft is driven, the drive member follows an elliptical path, the slide accommodating a gripping member for gripping and releasing the objects to be transferred.
Claim 3
Dependent Claim 52 words
A mechanism as claimed in claim 1, characterized in that the slide accommodates a structural member which is slidable against spring force, part of said structural member extending in said slot and being operable by the drive member, the structural member furthermore bearing against the gripping member and determining the positioning thereof.
