Abstract
Abstract An end position control robot constituted by a compound robot comprising a weight control apparatus a weight control robot having a link arm robot and a position control apparatus of a position control robot, both the apparatus being mechanically associated. The weight control apparatus is constructed so as to bear vertical load to control a vertical position and the position control apparatus is constructed in such a manner that a working end portion of the weight control apparatus is moved in a horizontal direction to carry out positioning, which leads to a precise positioning of the end portion of the arm in the case of load being transferred.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
148 words
An end position control robot, comprising: a main body; weight control means mounted on said main body, said weight control means comprising driving means mounted on said main body, an operating arm connected to said drive means for being moved with respect to said body and lifting means mounted on said operating arm for supporting a load and for moving said load vertically; position control means mounted in fixed position relative to said main body, said position control means comprising horizontal guide means and driving control means movable horizontally along said guide means to a selectable position thereon, said lifting means being coupled to said driving control means so that said lifting means can be operated to move a load vertically independently of said driving control means and so that said lifting means is movable horizontally by movement of said driving control means along said horizontal guide means.
Claim 2
Dependent Claim
148 words
An end position control robot, comprising: a main body; weight control means mounted on said main body, said weight control means comprising driving means mounted on said main body, an operating arm connected to said drive means for being moved with respect to said body and lifting means mounted on said operating arm for supporting a load and for moving said load vertically; position control means mounted in fixed position relative to said main body, said position control means comprising horizontal guide means and driving control means movable horizontally along said guide means to a selectable position thereon, said lifting means being coupled to said driving control means so that said lifting means can be operated to move a load vertically independently of said driving control means and so that said lifting means is movable horizontally by movement of said driving control means along said horizontal guide means.
Claim 3
Dependent Claim
109 words
An end position control robot according to claim 1, wherein said lifting means is a vertical rod which is connected to an end portion of said operating arm, said operating arm being a link arm suspended from said main body, said guide means comprising a guide rail, said driving control means comprising a cursor slidably mounted on said guide rail and driving means for moving said cursor along said guide rail, said vertical rod being engaged with said cursor so that said rod can be moved vertically relative to said cursor and so that said rod is moved horizontally by said cursor as it moves along said guide rail.
Claim 4
Dependent Claim
109 words
An end position control robot according to claim 1, wherein said guide means comprises first and second horizontal guide rails mounted at right angles to each other, first cursor means on said first guide rail, said first cursor means being slidably mounted on said second guide rail so that said first guide rail can be moved lengthwise along said second guide rail, a second cursor slidably mounted on said first guide rail, said lifting means comprising a vertical rod which engages said second cursor so that said rod can be moved vertically relative to said second cursor and so that said rod is moved horizontally by said second cursor.
Claim 5
Dependent Claim
38 words
An end position control robot according to claim 1, wherein said guide means comprises a guide rail, and support means for supporting said guide rail, in a forward position of the weight control means, in a horizontal plane.
Claim 6
Dependent Claim
91 words
An end position control robot according to claim 1, wherein said driving control means comprises a cursor, a driving member, a string member and a pulley, said driving member being fixed at one end of said guide means and said pulley being mounted on the other end of said guide means, said string member extending between both said driving member and said pulley and being connected to said cursor so that said cursor is moved along said guide means to a predetermined position by driving said driving means in either direction.
Claim 7
Dependent Claim
60 words
An end position control robot according to claim 1, wherein said driving control means comprises a cursor, a driving member, a rack, and a pinion, said rack being mounted on said guide means, said cursor being mounted on said driving member and being connected to said pinion so that rotation of said pinion moves said cursor along said guide means.
