Abstract

A high-speed stroke-type moving device for an elongate flexible body having at least one supply line. The device has a guideway for guided displacement of the body, having a spiral portion, in which at least part of the body is compactly accommodatable in a plurality of spaced tracks which are not in mutual contact and extend substantially spirally inwards. The invention provides that the body has a line guideway for the at least one supply line. According to the invention, the line guideway here has a first sub-portion which is guided in the spiral portion and an unguided second sub-portion having a first end which is connected at the end to the first sub-portion and a second end which is connected at the end to a rotary feedthrough for the at least one supply line. A corresponding device having an energy chain is furthermore disclosed.

Dependent claims

A high-speed stroke-type moving device for an elongate, flexible body, having at least one supply line and comprising:

a guideway for guided displacement of the body, having a spiral portion, in which at least part of the body is compactly accommodatable in a plurality of spaced turns which are not in mutual contact and extend spirally inwards,
wherein the guideway has two guide profiles arranged parallel opposite one another, wherein the course of the guide profiles defines the spiral portion,
wherein the body has a line guideway for the at least one supply line,
wherein the line guideway
comprises a first sub-portion which is guided in the spiral portion, wherein first sub-portion has journals or rollers projecting laterally at both sides, wherein the journals or rollers are slidingly or rollingly guided in the guide profiles, and
wherein the line guideway comprises an unguided second sub-portion having a first end which is connected to the first sub-portion and a second end which is connected to a rotary feedthrough for the at least one supply line.
