Systems for position determination using an energy chain for guiding supply lines, which energy chain has a movable run which is fixed at an end to a driver and a stationary run wherein the driver moves back and forth along a track. The system has a sensor device for position determination, which is attached to the driver. In one variant, the system comprises guide components, arranged along the track, for lateral guidance of the energy chain of which components at least one has a reference component acting as a position reference. In another variant of the system, at least each nth chain link of the energy chain has at least one reference component attached thereto. In both variants, the sensor device for position determination interacts with individual reference components, which allows better and more reliable determination of the current position.

The design of chain links for energy chains for movably carrying cables, hoses and the like. The chain link consists of a plurality of individual parts, namely two side plates made of plastic, comprising an interior side facing the interior of the chain link, an exterior side facing away therefrom and two narrow sides running substantially parallel to the longitudinal direction, and at least one, more particularly two transverse connecting pieces for detachably connecting the side plates, comprising a center part and a fastening portion at each end of the transverse connecting piece on both sides. The side plates have, on at least one narrow side, a corresponding fastening region for frictionally fastening a transverse connecting piece, namely a clamping receptacle which has two clamping surfaces, which are opposite one another in the longitudinal direction and between which a complementarily shaped fastening portion of the at least one separate transverse connecting piece is clamped. Each transverse connecting piece has two support protrusions on each fastening portion, each support protrusion having a support surface for resting against the interior side of the side plate in order to achieve a robust connection. Providing the side plate, in the central region between the fastening regions, with a special functional cut-out in the plate body, which cut-out facilitates additional functions or application expansions.

The invention relates to a winding device ( 10 ) for a line ( 1 ), such as a cable or hose, including a stationary frame ( 11 ) and a winding drum ( 12 ), which is rotatably mounted on said frame and has an interior ( 12 B). From the outside ( 12 A) of the winding drum ( 12 ), the line can be wound or unwound. An inner rotary guide ( 18 ) in the interior ( 12 B) guides the line ( 1 ) continuously from a fixed point (F) fixed with respect to the frame to a rotation point (R) on the winding drum ( 12 ) and defines a line course, having two opposite windings ( 18 A, 18 B) about the axis of rotation (A), and a rotatable deflection element ( 18 C), in which the line changes over. According to the invention, the winding drum ( 12 ) has a first cut-out ( 15 A) at a first end, on the side of the rotation point (R), which cut-out opens out axially and at an end face, and a retaining part ( 19 B) at the other end, which retaining part is rotationally fixed to the frame, has a second cut-out ( 15 B), which opens outward in a plane perpendicular to the axis of rotation (A). By virtue of the cut-outs ( 15 A, 15 B) in combination with the special rotary guide ( 18 ), the line ( 1 ) to be wound can be continuously routed without interruption and without rotational coupling or be subsequently attached, from the outside ( 12 A) through the first cut-out ( 15 A), in the inner rotary guide ( 18 ) and from the fixed point (F) of the rotary guide through the second cut-out ( 15 B) or vice versa.

A fastening part for fastening a cable carrier to a component, said fastening part comprising: a foot web which can be arranged on a component so as to extend in the peripheral direction thereof and has holding means in its end regions for a first fastening element for fastening the fastening part to the component; and a fastening web which extends in the direction of the foot web and which has multiple fastening means for fastening a differently designed second fastening element for fastening a cable carrier to the fastening part; wherein the foot web and the fastening web are connected to one another in their central region via a connecting element, and side regions of the fastening web extending beyond the connecting element have at least some of the fastening means as first fastening means.

A monitoring system for monitoring the condition of and energy guide chain and/or a cable guided in an energy guide chain. Energy guide chains are used for guiding cables, hoses or the like, between abase and a moving end displaceable along a travel path and, in so doing, form a mobile run connected to the moving end, a stationary run with a connection end for the base and a deflection arc between the two runs. A monitoring device with at least one sensing component arranged on the energy guide chain. The monitoring device evaluates a signal generated using the sensing component in order to monitor the occurrence of a fault condition during operation of the energy guide chain. The sensing component includes an electrical indicator conductor guided by the energy guide chain and extending along the greater part of the length of the mobile run. To monitor the condition of a cable and in this case includes two electrical indicator conductors guided by the energy guide chain, the one end of which is connected to the monitoring device and the other end of which is short-circuited.

A protective cable conduit for lines in a clean room application, with a flexible encasement which is movable back and forth for routing a line. Each receptacle extends in channel-like fashion from a first end to a second end. The encasement comprises at least one encasing unit, which forms the at least one receptacle for a line. The encasing unit has a first fastening strip on one longitudinal side and a second fastening strip on the other longitudinal side. The first and the second fastening strip are designed for releasable connection by interlocking engagement and/or frictional engagement, for example with a cooperating hook profile and claw profile, and are connectable to one another in a connection direction transverse to the longitudinal direction. A plurality of encasing units can thus be fastened to one another releasably using mating fastening strips by connecting the fastening strips in a connection direction transverse to the longitudinal direction. An arrangement of a protective cable conduit with support chains, wherein each support chain is routed in an associated encasing unit which accommodates only the associated support chain(s), such that this is replaceable separately from lines routed in the encasement.

An energy guide chain including two plate comprising successive chain plates which respectively partially overlap with each other in overlap regions. A respective side part of plastic is associated with each second chain plate. The chain plates are made from a different material from the side parts and have through apertures in their overlap regions. In its two end regions each side part has a plurality of projections which respectively engage through the overlapping apertures in the associated chain plate and the respectively adjoining chain plate to limit the relative pivotal angle of successive chain plates and/or to connect same. In addition there is proposed a two-part separating web for an energy guide chain, wherein the first part has at least one securing pin and the second part has at least one securing receiving means so that the two parts can be connected and released in a direction perpendicular to the main plane of the separating web.

An end fastening part for an energy chain, for connecting to a link plate of a terminal chain link at one end and to a connection point on a system part at the other end. The single-piece end fastening part has a main plane and comprises: an overlapping region having a side wall for connecting to a link plate; a frame-type fastening region having a frame, in which a plurality of fastening holes is provided, for fastening to a connection point; and, therebetween, a transition region, in which a concave end face is provided.
