BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a device for the propulsion of a tumbler body and, more particularly, to a device for the propulsion of a tumbler body in the shape of an oloid.
2. History of the Related Art
CH-patent 500 000 describes a device for the generation of a tumbling motion. This device consists of a body that Paul Schatz, in his book "Rhythmusforschung and Technik" (Stuttgart 1975), refers to as an "oloid." This oloid, according to CH-A1 500 000, is driven by a conveyor belt which carries the oloid. This drive was not very popular in practical applications, because it requires a perfectly shaped oloid and no slip during the rolling of the oloid. Guide rollers, which are commonly used on drum-shaped rolling elements, cannot be used with the shape of the oloid. Even though it has, much like a cylinder, a straight contact line on one plane, the angle of this contact line changes in an oscillatory manner with respect to the direction of travel. Therefore, the invention never became successful. This is not the case with the solution presented in CH-patent 216 760 in which a hollow body, executing a tumbling motion, is part of a half Bricard chain. This solution has been successful in the market employing various designs and different means of propulsion. But it has the tremendous disadvantage that prevents the construction of a mixer based on the oloid or inversion principle with a capacity of one or more cubic meters. This disadvantage is caused by the high mass forces occurring during operation that constantly change in size and direction. These mass forces require extremely large components and, thus, represent extreme challenges to the base of such a machine.
The purpose of this invention is the creation of a drive for an oloid body that overcomes these disadvantages and is also suited for oloids with large dimensions.
SUMMARY OF THE INVENTION
The present invention relates to a device for the propulsion of a tumbler body. More particularly, one aspect of the invention comprises a device for the propulsion of a tumbler body consisting of an oloid tumbler body, a rolling device and means for the propulsion and guidance of the tumbler body positioned on the rolling device characterized by two profiles leading around the tumbler body and attached to it arranged in such a way that they are located on the edges of a strip which is continuous and straight for the level rolling of the tumbler body and positioned in its longitudinal axis. A second strip is placed on top of the first strip that is attached to the tumbler body and carries the profiles and has those form elements suitable for the positive connection of a driving element. A frame supports the rolling device on which the tumbler body is positioned and which is passively moved by it. The frame supports the guiding and driving system in which the means for the propulsion and guiding of the tumbler body are installed and collected. Rollers are provided in the guiding and driving system to apply the guiding forces on the profiles. A driving element is provided in the form of a conveyor belt that is positioned along the second strip around the tumbler body and forms a positive connection with it. A driving wheel is positioned in the guiding and driving system around which forms a positive connection with the driving element and can be driven by the driving wheel. Two fairleads are provided in the guiding and driving system for the shifting of the driving element from the positive connection on the second strip to the driving wheel, with the fairleads as closely arranged as possible to the second strip and each other.
In another aspect, the above described invention includes the tumbler body being an oloid hollow body, and the rolling device is a roller carpet consisting of free-moving rollers running parallel to each other, with the axial direction of the rollers forming the roller carpet perpendicular to the rolling direction of the hollow body.
