Abstract An endlessly circulating link conveyor with energy supply from a stationary source comprises a plurality, of links (1) that are connected to one another such that they can pivot with respect to one another, jointly form a link conveyor that follows a running path over deflection rollers (6) and can be driven in circulating fashion, an energy guiding chain (30), one end of which travels with the link conveyor and the other end of which is arranged in rotating fashion within the circulatory path, and via which the link conveyor can be connected to supply lines (36), where the links (1) of the link conveyor display a channel (2) for receiving distribution lines (40) and, laterally next to the channel, a guide groove (3) for guiding the energy guiding chain (30), where the upper face of at least one of the links (1) displays a mounting surface for consumers, and one of the links (1) is equipped for connecting the travelling end (32) of the energy guiding chain (30). ## Claims ### Claim 1 Endlessly circulating link conveyor with energy supply from a stationary source, comprising a plurality of links that are connected to one another such that they can pivot with respect to one another, jointly form a link conveyor that follows a running path over deflection rollers and can be driven in circulating fashion, an energy guiding chain, one end of which travels with the link conveyor and the other end of which is arranged in rotating fashion within the circulatory path, and via which the link conveyor can be connected to supply lines, where the links of the link conveyor display a channel for receiving distribution lines and, laterally next to the channel, a guide groove for guiding the energy guiding chain, where the upper face of at least one of the links displays a mounting surface for consumers, and one of the links is equipped for connecting the travelling end of the energy guiding chain. ### Claim 2 (depends on 1) Link conveyor according to claim 1, where connecting elements for articulated connection of pairs of adjacent links are provided, engaging corresponding hinge mounts of the links by means of pivot pins. ### Claim 3 (depends on 1) Link conveyor according to claim 1, where connecting elements for articulated connection of pairs of adjacent links are provided, displaying hinge mounts that are engaged by corresponding pivot pins of the links. ### Claim 4 (depends on 1) Link conveyor according to claim 1 one of the preceding Claims, where the links or the connecting elements display lateral projections for guiding the link conveyor in corresponding guide rails. ### Claim 5 (depends on 1) Link conveyor according to claim 1 one of the preceding Claims, where the underside of some links is provided with a tooth structure, oriented transversely to the direction of circulation, for engaging a complementary tooth structure of a driving mechanism, where the tooth structure of the link extends over the area below the channel. ### Claim 6 Link for a link conveyor, with a longitudinal extension and a transverse extension, containing a channel for receiving distribution lines that extends in the longitudinal direction, and laterally next to the channel, a guide groove, open towards the top and extending in the longitudinal direction, for sliding reception of an energy guiding chain, as well as hinge pins or hinge mounts, extending in the transverse direction on both sides, for articulated connection to at least two further links. ### Claim 7 (depends on 6) Link according to claim 6, where the underside of the link displays a tooth structure extending in the transverse direction below the channel. ### Claim 8 (depends on 6, 7) Link according to claim 6 or 7, where the upper side displays a mounting plate for attaching consumers. ### Claim 9 Link conveyor arrangement, comprising a circulating link conveyor, a supporting frame with upper and lower guide rails, in which the linear circulating stretch of the link conveyor is laterally guided, deflection rollers, via which the link conveyor can be transferred from the upper guide rail to the lower guide rail, an energy guiding chain for supply lines, where one end of the energy guiding chain is located centrally within the circulatory path in rotating fashion and the other end of the energy guiding chain is connected to a link of the link conveyor, via which the link conveyor can be connected to the supply lines, where the link conveyor comprises a plurality of links, each of which displays a channel, extending in the direction of circulation of the link conveyor, for receiving distribution lines, and a guide groove, located next to the channel, that is open towards the inside of the circulatory path and in which the lower strand of the energy guiding chain is laterally guided. ### Claim 10 (depends on 9) Link conveyor arrangement according to claim 9, where the side of at least some of the links that faces towards the inside of the circulatory path displays a tooth structure that is oriented transversely to the direction of circulation and extends over the area below the channel. ### Claim 11 (depends on 9) Link conveyor arrangement according to claim 9, where one of the deflection rollers can be driven in rotating fashion.
