Abstract

The invention relates to a line guiding system (1) for accommodating and guiding supply lines between two connection points (2.1, 2.2) that can be moved relative to one another in a circular motion with respect to a rotational axis (d) over a rotational angle range, wherein the line guiding system (1) has an elongated strand (3.1, 3.2, 3.3) coupled to the connection points (2.1, 2.2), on or in which strand the supply lines can be arranged in a guided manner, and the strand (3.1, 3.2, 3.3) can be moved back and forth within the rotational angle range while guided over a circular arc, such as to form a first run (4.1), a second run (4.2), and a deflecting bend (5) that connects the first run (4.1) and the second run (4.2). In order to enable guidance of the supply lines over an increased rotational angle range, at least two strands, a first strand (3.1) and a second strand (3.2), are provided, which are arranged such as to be coupled one behind the other.

Dependent claims

A line guide system to receive and guide supply lines between two connection points, wherein the two connection points are movable relative to each other in a circular movement with respect to a rotary axis over a rotary angle range,

wherein the line guide system has an elongate strand which is coupled to the connection points and at or in which the supply lines are arrangeable in guided relationship, and the strand is reciprocatingly displaceable guidedly over a circular arc within the rotary angle range, forming a first run, a second run and a deflection arc connecting the first and second runs together,
wherein at least two strands comprising a first strand and a second strand are arranged coupled one behind the other, and a guide system to guide the strands, the guide system having three guide units which are rotationally movable relative to each other with respect to the rotary axis, with respect to the direction of succession a front guide unit, a central guide unit and a rear guide unit,
wherein the guide units are arranged in two axially spaced planes, a first plane and a second plane, perpendicularly to the rotary axis,
wherein the first strand is fixed to the front and central guide units, and
wherein the second strands is fixed to the central and rear guide units.
