Three dimensional movement of a robot manipulator

Claim 2

In a system for moving a manipulator mounted on carriage means, the combination comprising: a carrier for a rail bar being preferably of hollow section type configuration, and being generally straight but with a relatively high tolerance as to straightness; a plurality of rail support bars being spaced apart as mounted to the carrier but in true alignment for adapting for lack of straightness of the carrier and establishing low tolerance straight mounting surfaces; each support bar having a plurality of threaded bores, there being threaded plugs each with an opening respectively in said bores; bolt means traversing the openings with play but clamping the respective support bar in relation to the carrier; and a straight rail bar mounted on said plurality of support bars for said carriage means to run on, said rail bar being kept straight as mounted.

Claim 3

The combination as in claim 1, said support bars each having two ridges for mounting said rail bar in between.

Claim 4

The combination as in claim 2, said rail bar being bolted to said ridges.

Claim 5

The combination as in claim 2, said rail bar being bolted to support portions of the support bars in between the respective ridges.

Claim 6

The combination as in claim 1, the plugs projecting from the respective support bar to establish an adjustable gap between the respective support bar and the carrier, to thereby compensate for carrier unevenness.

Claim 7

The combination as in claim 1, there being a rack bolted to the rail bar, the carriage means provided with drive means for a pinion, meshing the rack for driving the carriage along the rail bar.

Claim 8

The combination as in claim 1, there being rollers laterally engaging the rail bar.

Claim 9

In a system for moving a manipulator mounted on a carriage, a track system comprising: a first and a second rail carrier mounted and interconnected to extend parallel to each other in spaced apart relationship; a carrier carriage; a plurality of nonstraightness compensating support bars mounted on the rail carriers, at least two per carrier, as well as on the carrier carriage and in aligned relationship as to each carrier to establish straight rail mounting facilities; a first, second and third rail bar means respectively mounted to said first and second rail carriers and the carrier carriage by means of the support bars; each support bar having a plurality of threaded bores, there being threaded plugs each with an opening respectively in said bores; bolt means traversing the openings with play but clamping the support in relation to the respective one of the carriers; and said carrier carriage running on the first and second rail bar means, the carriage running on the third rail bar means.

Claim 10

In a system for moving a manipulator mounted on a carriage, a track system comprising: a first and a second rail carrier mounted and interconnected to extend parallel to each other in spaced apart relationship; a carrier carriage; a plurality of nonstraightness compensating support bars mounted on the rail carriers, at least two per carrier, as well as on the carrier carriage and in aligned relationship as to each carrier to establish straight rail mounting facilities; a first, second and third rail bar means respectively mounted to said first and second rail carriers and the carrier carriage by means of the support bars; each support bar having a plurality of threaded bores, there being threaded plugs each with an opening respectively in said bores; bolt means traversing the openings with play but clamping the support in relation to the respective one of the carriers; and said carrier carriage running on the first and second rail bar means, the carriage running on the third rail bar means.

Claim 11

A track system as in claim 8 the plugs projecting from the respective support bar to establish an adjustable gap between the respective support bar and the carrier to thereby compensate for carrier unevenness.

Claim 12

In a system for moving a manipulator mounted on a carriage, a track system comprising: a first and a second rail carrier mounted and interconnected to extend parallel to each other in spaced apart relationship; a carrier carriage; a plurality of nonstraightness compensating support bars mounted on the rail carriers, at least two per carrrier, as well as on the carrier carriage and in aligned relationship as to each carrier to establish straight rail mounting facilities; a first, second, and third rail bar means respectively mounted to said first and second rail carriers, and the carrier carriage by means of the support bars; the carrier carriage having one portion with two rollers running on the first rail bar means and another portion with a single roller running on the second rail bar means; a drive motor driving said one portion; and the carriage running on the third rail bar means.

Claim 13

In a system for moving a manipulator mounted on a carriage, a track system comprising: a first and a second rail carrier mounted and interconnected to extend parallel to each other in spaced apart relationship; a carrier carriage; a plurality of nonstraightness compensating support bars mounted on the rail carriers, at least two per carrrier, as well as on the carrier carriage and in aligned relationship as to each carrier to establish straight rail mounting facilities; a first, second, and third rail bar means respectively mounted to said first and second rail carriers, and the carrier carriage by means of the support bars; the carrier carriage having one portion with two rollers running on the first rail bar means and another portion with a single roller running on the second rail bar means; a drive motor driving said one portion; and the carriage running on the third rail bar means.

Claim 14

A track system as in claim 10, there being a rack on the first rail bar means meshing a pinion driven by the drive motor.

Claim 15

A track system as in claim 10, the single roller being larger than the two rollers.
