Abstract
Abstract An industrial robot including a hollow arm pan ( 1 ) rotatable around its longitudinal axis (A) through which a cable set ( 4 ) is drawn through and connected to a robot unit ( 3 ) rotatable around an axis (A). The arm part and the robot unit are arranged for both rotation and bending relative to one another. The cable set ( 4 ) is guided and supported by a supporting means ( 5 ) rotatably arranged within arm part ( 1 ) so that the bending movement is accommodated by the part of the cable that is located between the supporting means ( 5 ) and the robot unit ( 3 ) and the rotational movement is accommodated by the part of the cable set that is located within the arm part ( 1 ) before the supporting means ( 5 ) when viewed from the power source (D).

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
88 words
An industrial robot including a hollow arm part rotatable around its longitudinal axis, a robot unit rotatable around its center axis and a cable set extending through the arm part and being connected to the robot unit, the arm part and the robot unit being arranged for both rotation and bending relative to one another, and the cable set being radially fixed in a guiding supporting means arranged within the arm part where the supporting means is arranged to rotate substantially in step with the rotating robot unit.
Claim 2
Dependent Claim
88 words
An industrial robot including a hollow arm part rotatable around its longitudinal axis, a robot unit rotatable around its center axis and a cable set extending through the arm part and being connected to the robot unit, the arm part and the robot unit being arranged for both rotation and bending relative to one another, and the cable set being radially fixed in a guiding supporting means arranged within the arm part where the supporting means is arranged to rotate substantially in step with the rotating robot unit.
Claim 3
Dependent Claim
17 words
The industrial robot according to claim 1 , wherein the cable set is arranged as a ribbon.
Claim 4
Dependent Claim
20 words
The industrial robot according to claim 1 , wherein the supporting means is arranged to slide along the longitudinal axis.
Claim 5
Dependent Claim
24 words
The industrial robot according to claim 3 , wherein the supporting means is arranged to slide along a limited length of the longitudinal axis.
Claim 6
Dependent Claim
19 words
The industrial robot according to claim 1 , wherein the supporting means is firmly attached to the longitudinal axis.
Claim 7
Dependent Claim
16 words
The industrial robot according to claim 1 , wherein the arm part comprises an upper arm.
Claim 8
Dependent Claim
15 words
The industrial robot according to claim 1 , wherein the robot comprises a welding robot.
Claim 9
Dependent Claim
19 words
The industrial robot according to claim 1 , wherein the robot unit comprises a rotating disc for a tool.
Claim 10
Independent Claim
127 words
A method of manufacturing an industrial robot having a hollow arm part rotatable about its longitudinal axis, a cable set extending through the arm and being connected to a robot unit rotatable about an axis at which the arm part and the robot unit are arranged for both rotation and bending relative to one another, comprising the steps of providing a supporting means rotatably arranged within the arm part for guiding and supporting the cable set, accommodating the bending by that part of the cable set located between the supporting means and the robot unit, and accommodating the rotation by that part of the cable set that is located within the arm part before the supporting means when viewed from a power source provided for the robot.
Claim 11
Independent Claim
127 words
A method of manufacturing an industrial robot having a hollow arm part rotatable about its longitudinal axis, a cable set extending through the arm and being connected to a robot unit rotatable about an axis at which the arm part and the robot unit are arranged for both rotation and bending relative to one another, comprising the steps of providing a supporting means rotatably arranged within the arm part for guiding and supporting the cable set, accommodating the bending by that part of the cable set located between the supporting means and the robot unit, and accommodating the rotation by that part of the cable set that is located within the arm part before the supporting means when viewed from a power source provided for the robot.
Claim 12
Dependent Claim
24 words
The method according to claim 9 , wherein the supporting means is caused to slide along the axis of rotation within the arm part.
Claim 13
Dependent Claim
22 words
The method according to claim 9 , wherein the robot unit and the supporting means are caused to rotate essentially in synchrony.
