Abstract

The present application comprises a loading gantry with at least one carriage traversable on a horizontal guide rail, in particular for the transport of workpieces between stations of a production system. In accordance with the application the loading gantry includes a media station which in at least one position of the carriage releasably can be mechanically coupled with the same in order to produce at least one media connection between the media station and the carriage.

Claims

1. A loading gantry with at least one carriage traversable on a horizontal guide rail, the loading gantry including a media station which in at least one position of the carriage is releasably mechanically coupled to the carriage in order to produce at least one media connection between the media station and the carriage.

2. The loading gantry according to claim 1, wherein the media station includes at least one port which in at least one position of the carriage can be coupled with a port of the carriage in order to transmit the at least one medium to the carriage.

3. The loading gantry according to claim 1, wherein at least one medium is a granular, pasty, liquid and/or gaseous medium.

4. The loading gantry according to claim 1, wherein the carriage can be charged with hydraulic and/or pneumatic pressure via the media station.

5. The loading gantry according to claim 1, wherein a lubricant system of the carriage can be charged with lubricant via the media station.

6. The loading gantry according to claim 1, wherein the carriage can be charged with coolant via the media station.

7. The loading gantry according to claim 1, wherein a data and/or signal connection can be produced between the carriage and the media station.

8. The loading gantry according to claim 1, wherein via the media station the carriage can be supplied with elements and/or media which via an actuator of the carriage are installed and/or consumed for machining a workpiece, the elements and/or media comprise one or more of:

electronic and/or mechanical small parts, welding wire and/or solder wire and/or blasting grit for sand blasting.

9. The loading gantry according to claim 1, wherein the carriage can be supplied with electric energy via the media station, wherein in at least one position of the carriage a contact element of the media station is conductively connectable with a contact element of the carriage.

10. The loading gantry according to claim 1, wherein at least one media station is arranged in a working position, in which the carriage stops over a station of the machining system in order to deposit or pick up a workpiece, and/or in a parking position of the carriage.

11. The loading gantry according to claim 1, wherein the carriage includes two grippers which each are movable in vertical direction, wherein the loading gantry includes a control unit by which in a first position of the carriage the one gripper is actuated to remove a machined workpiece from a machining station and in a second position of the carriage the other gripper is actuated to deposit a new workpiece at the machining station, wherein between the removal of the machined workpiece in the first position of the carriage and the deposition of the new workpiece in the second position of the carriage the carriage is traversed from the first to the second position along the horizontal guide rail in order to sequentially arrange the one and the other gripper over the machining station.

12. The loading gantry according to claim 9, wherein the charging device is configured such that charging of the energy accumulator can be effected both in the first and in the second position of the carriage, and/or charging can be effected in all intermediate positions between the first and the second position.

13. The loading gantry according to claim 1, wherein the drive of the carriage along the guide rail is effected via a drive element of the carriage which meshes with a rack of the guide rail, and/or wherein the carriage includes a component which is at least also movable in vertical direction, wherein the component serves for moving the workpieces in vertical direction and/or carries a gripper, wherein the component includes a vertically movable linear axis and/or a robot arm with a plurality of swivel and/or rotation axes.

14. The loading gantry according to claim 1, wherein the loading gantry is a linear gantry or an area gantry and/or wherein the guide rail is supported via one or more props.

16. The loading gantry according to claim 2, wherein coupling is effected by an actuator of the media station and/or the carriage and/or the ports each include a valve which closes the ports when the coupling with the respective other port is released.

17. The loading gantry of claim 4, wherein the carriage includes a hydraulic and/or pneumatic actuator which is operable via the hydraulic and/or pneumatic pressure supplied via the media station, wherein the hydraulic and/or pneumatic pressure serves for actuating the actuator while the carriage is disposed in the vicinity of the media station, and/or wherein the hydraulic and/or pneumatic pressure serves for charging a hydraulic and/or pneumatic accumulator of the carriage.

18. The loading gantry of claim 6, wherein the carriage in the at least one position can be connected to a coolant circuit of the media station in order to cool a component of the carriage.

19. The loading gantry of claim 7, wherein the data and/or signal connection is established by producing an electrically conductive connection between ports of the carriage and the media station.

20. The loading gantry of claim 9, wherein the carriage includes at least one electric drive and an electric energy accumulator for at least partly supplying the drive with energy, and the loading gantry comprises a charging device for charging the electric energy accumulator, and/or wherein the loading gantry includes a control unit which activates the power supply by the charging device only after the conductive connection between the charging device and the carriage has been produced.

21. A production system comprising a plurality of stations and a loading gantry according to claim 1 for the transport of workpieces between the plurality of stations.

15. A media station and/or carriage of a loading gantry,

the carriage traversable on a horizontal guide rail, for the transport of workpieces between stations of a production system,

the media station releasably mechanically coupled to the carriage in at least one position of the carriage forming at least one media connection between the media station and the carriage.
