Document Type and Number:
Japanese Patent JPH04500336
Kind Code:
A
Abstract:
The invention relates to a device for the rapid positioning of a heavy carriage (301). The carriage (301) is finely positioned by means of a stationary positioning bar, for instance a part of a linear electric motor or a gear rack (303), and a cooperating moving part of the linear motor or a motor (304) attached to the carriage (301). For the case including a gear rack (302) said motor (304) is provided with a gear wheel (305) for engagement with a gear rack. The carriage (301) is rapidly and roughly displaced by means of a further means. This further means may be constituted by a further gear wheel (401), which cooperates with a gear rack (303) and is driven by a separate motor attached to the carriage (301). This further means will in addition deliver a certain force for the final positioning, in such a way that the play between the gear wheel (305) and the gear rack (303) is eliminated by biasing. Instead of a second gear wheel (401) a toothed belt, a pneumatic cylinder or other linear motor may be used. In this case these are mounted separate from the carriage and are principally fixed in space.
