Abstract

A linear transport system can have a carriage guide rail having a first and a second carriage, which are arranged in such a way that they can be moved independently of one another on the carriage guide. The XY table for this linear transport system can comprise a carrying structure and a first and a second linear guide, which are embodied with an angular offset relative to one another and each have a first and a second guide element, e.g., which can be moved relative to one another along a linear track. In one arrangement, the first guide elements of the first and second linear guides are connected to the carrying structure. The second guide element of the second linear guide can be connected to the first carriage and the second guide element of the second linear guide can be connected to the second carriage.

First claim

What is claimed is:

1. An XY table for a linear transport system, having a carriage guide rail and a first and a second carriage, which are arranged in such a way that they can be moved independently of one another on the carriage guide rail, which has a curved portion, comprising
a carrying structure and
a first and a second linear guide, which are embodied with an angular offset relative to one another and each have a first and a second guide element, which can be moved relative to one another along a linear track,
wherein the first guide elements of the first and second linear guides are connected to the carrying structure, and
wherein the second guide element of the first linear guide can be connected to the first carriage and the second guide element of the second linear guide can be connected to the second carriage,
wherein, when the first and the second linear guide are oriented parallel to the track plane of the carriage guide rail, the first guide elements of the first and second linear guides are connected to the carrying structure, the first guide elements being allowed rotation in the track plane of the carriage guide rail, and/or the second guide element of the first linear guide is connected to the first carriage, and the second guide element of the second linear guide is connected to the second carriage, the second guide elements being allowed rotation in the track plane of the carriage guide rail, or
wherein, when the first and the second linear guide are oriented in a plane of orientation perpendicular to the track plane of the carriage guide rail, the first guide elements of the first and second linear guides are connected to the carrying structure, the first guide elements being allowed tilting in the plane of orientation, and/or the second guide element of the first linear guide is connected to the first carriage, and the second guide element of the second linear guide is connected to the second carriage, the second guide elements being allowed tilting in the plane of orientation.

2. The XY table as claimed in claim 1 , wherein the first guide elements of the first and second linear guides are each guide rails, and the second guide elements of the first and second linear guides are each sliding elements.

3. The XY table as claimed in claim 1 , wherein the first guide elements of the first and second linear guides are connected to the carrying structure, and/or the second guide element of the first linear guide is connected to the first carriage, and the second guide element of the second linear guide is connected to the second carriage, in each case via a rotary joint.

4. The XY table as claimed in claim 1 , comprising a tilting device, which is arranged between the first guide elements of the first and second linear guides and the carrying structure and/or between the second guide element of the first linear guide and the first carriage and the second guide element of the second linear guide and the second carriage and is designed to be tiltable perpendicularly to the track plane of the carriage guide rail.

5. The XY table as claimed in claim 4 , wherein the tilting device has at least one hinge joint having a triggering element, wherein the linear transport system comprises a further carriage having a tilting element, which is designed to actuate the hinge joint upon engagement with the triggering element in order to bring about a tilting movement of the carrying structure.

6. The XY table as claimed in claim 1 , comprising a third linear guide, which is arranged between the second guide elements of the first linear guide and the first carriage and between the second guide element of the second linear guide and the second carriage and is designed in such a way that the first and the second carriage can be moved relative to one another along a linear track.

7. The XY table as claimed in claim 6 , wherein the third linear guide has a guide rail and a sliding element, wherein the guide rail can be connected to the first carriage, and the sliding element can be connected to the second carriage.

8. A linear transport system, having
a carriage guide rail, which has an arc segment,
a first and a second carriage, which are arranged in such a way that they can be moved independently of one another on the carriage guide rail, and
an XY table comprising a carrying structure and a first and a second linear guide, which are embodied with an angular offset relative to one another and each have a first and a second guide element, which can be moved relative to one another along a linear track,
wherein the first guide elements of the first and second linear guides are connected to the carrying structure,
wherein the second guide element of the first linear guide is connected to the first carriage and the second guide element of the second linear guide is connected to the second carriage in order to carry out a movement of the XY table along the transfer path in the X direction in the case of a joint movement of the two carriages and to carry out a movement of the XY table transversely to the transfer path in the Y direction in the case of a relative movement of the two carriages,
wherein the first and the second linear guide are oriented parallel to the track plane of the carriage guide rail, and
wherein the first guide elements of the first and second linear guides are connected to the carrying structure, the first guide elements being allowed rotation in the track plane of the carriage guide rail, and/or the second guide element of the first linear guide is connected to the first carriage, and the second guide element of the second linear guide is connected to the second carriage, the second guide elements being allowed rotation in the track plane of the carriage guide rail.

9. The linear transport system as claimed in claim 8 , wherein the first guide elements of the first and second linear guides are each guide rails, and the second guide elements of the first and second linear guides are each sliding elements.

10. The linear transport system as claimed in claim 8 , wherein the first guide elements of the first and second linear guides are connected to the carrying structure, and/or the second guide element of the first linear guide is connected to the first carriage, and the second guide element of the second linear guide is connected to the second carriage, in each case via a rotary joint.

11. The linear transport system as claimed in claim 8 , comprising a tilting device, which is arranged between the first guide elements of the first and second linear guides and the carrying structure and/or between the second guide element of the first linear guide and the first carriage and the second guide element of the second linear guide and the second carriage and is designed to be tiltable perpendicularly to the track plane of the carriage guide rail.

12. The linear transport system as claimed in claim 11 , wherein the tilting device has at least one hinge joint having a triggering element, wherein the linear transport system comprises a further carriage having a tilting element, which is designed to actuate the hinge joint upon engagement with the triggering element in order to bring about a tilting movement of the carrying structure.

13. The linear transport system as claimed in claim 8 , comprising a third linear guide, which is arranged between the second guide elements of the first linear guide and the first carriage and between the second guide element of the second linear guide and the second carriage and is designed in such a way that the first and the second carriage can be moved relative to one another along a linear track.
