Mixing device having a bearing for a receiving device

摘要

Disclosed is a mixing device for mixing, in particular, contents of laboratory vessels. The mixing device has a receiving device for receiving mixtures, a drive for setting the receiving device in a mixing movement relative to a chassis in which the receiving device moves on a closed path, and a bearing for guiding the receiving device in the mixing movement. The bearing has at least two supports, each with two bearing areas spaced apart from each other and having at least substantially no translatory and at least two rotational degrees of freedom. One bearing area bears the support at the chassis, and the other bearing area bears the receiving device at the support. The bearing has a guidance device, which guides the rotation of the receiving device relative to the chassis during the mixing movement.

主权项

1. A mixing device comprising:
a chassis; a receiving device for receiving mixtures and having a drive by means of which the receiving device is set in a mixing movement in a substantially horizontal plane relative to the chassis in which the receiving device moves on a closed path, periodically returning to a specific position in a specific alignment in space, and a bearing which guides the receiving device to reduce deviations from the horizontal plane in the mixing movement, wherein the bearing comprises:
at least two supports, each support having two bearing areas spaced apart from each other, the two bearing areas having substantially no translatory and at least two rotational degrees of freedom, wherein one bearing area of each support mounts the respective support to the chassis and the other bearing area mounts the receiving device to the respective support, anda guidance device which guides the rotation of the receiving device relative to the chassis during the mixing movement, wherein the guidance device has at least one web which connects two of the at least two supports, wherein a first and a second hinge joint, both having no translatory and only one rotational degree of freedom, mount the web between the at least two supports and the first and second hinge joints have axes parallel to each other and are rotatable around the axes.
