Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
203 words
An industrial robot having a stationary robot base, a vertical motion unit mounted on said robot base, a rotary motion unit mounted on said vertical motion unit, and a robot hand attached to a horizontal robot arm by means of a robot wrist forming part of said rotary motion unit, and having a hollow structure defining a vertical cavity formed as a wiring and piping space comprising: vertical guides and a vertical feed mechanism mounted on said stationary robot base; a hollow frame member forming the body of said vertical motion unit and extending vertically from immediately above said stationary robot base, said hollow frame member having formed externally thereon slides fitted on said vertical guides and a projecting interlocking member engaged with said vertical feed mechanism for imparting vertical motion; and an upper support plate fixed to the upper end of said hollow frame member and having rotatably mounted thereon a tubular member supporting thereon said rotary motion unit, said tubular member being disposed so as to be substantially in alignment with said hollow frame member, whereby said hollow frame member and said tubular member form a hollow vertical structure extending from said stationary robot base up into said rotary motion unit.
Claim 2
Dependent Claim
203 words
An industrial robot having a stationary robot base, a vertical motion unit mounted on said robot base, a rotary motion unit mounted on said vertical motion unit, and a robot hand attached to a horizontal robot arm by means of a robot wrist forming part of said rotary motion unit, and having a hollow structure defining a vertical cavity formed as a wiring and piping space comprising: vertical guides and a vertical feed mechanism mounted on said stationary robot base; a hollow frame member forming the body of said vertical motion unit and extending vertically from immediately above said stationary robot base, said hollow frame member having formed externally thereon slides fitted on said vertical guides and a projecting interlocking member engaged with said vertical feed mechanism for imparting vertical motion; and an upper support plate fixed to the upper end of said hollow frame member and having rotatably mounted thereon a tubular member supporting thereon said rotary motion unit, said tubular member being disposed so as to be substantially in alignment with said hollow frame member, whereby said hollow frame member and said tubular member form a hollow vertical structure extending from said stationary robot base up into said rotary motion unit.
Claim 3
Dependent Claim
22 words
An industrial robot as set forth in claim 1, wherein said tubular member forms a driven element of said rotary motion unit.
Claim 4
Dependent Claim
26 words
An industrial robot as set forth in claim 2, further comprising a rotation drive mechanism for said rotary motion unit supported on said upper support plate.
Claim 5
Dependent Claim
37 words
An industrial robot as set forth in claim 3, further comprising electrical wiring cables extending from a position adjacent said stationary robot base, through said hollow frame member and said tubular member, into said rotary motion unit.
