Abstract

A method for assigning a workpiece to be processed to a mobile unit of an indoor location system used in a manufacturing hall in industrial processing of workpieces is provided. The method includes: providing a manufacturing control system for the industrial processing of workpieces with a machine tool in accordance with workpiece-specific processing plans, providing an assistance system for collecting measurement assistance workpiece data sets for the workpieces, detecting a workpiece to be assigned with the assistance system and generating a measurement-assistance-workpiece data set for the workpiece, comparing the measurement-assistance-workpiece data set with a processing plan-assistance-workpiece data set corresponding to the workpiece to identify a processing plan, providing a mobile unit assigned to the identified processing plan, the indoor location system configured to determine a position of the mobile unit, and spatially assigning the workpiece to the mobile unit assigned to the identified processing plan.

First claim

What is claimed is:

1. A method of assigning workpieces to be processed to mobile transceivers of an indoor location system used in a manufacturing hall, the method comprising:
providing a manufacturing control system for industrial processing of workpieces with a machine tool according to workpiece-specific processing plans, wherein order information of the workpieces is defined respectively in the workpiece-specific processing plans and includes at least one of processing parameters, workpiece parameters, or at least one processing plan-assistance-workpiece data set;
providing an assistance system adapted to acquire measurement-assistance-workpiece data sets for the workpieces;
detecting a workpiece to be assigned with the assistance system and generating a measurement-assistance-workpiece data set for the workpiece;
identifying a processing plan associated with the workpiece by comparing the measurement-assistance-workpiece data set generated for the workpiece with a processing plan-assistance-workpiece data set corresponding to the workpiece;
providing at least one mobile transceiver assigned to the identified processing plan, wherein the indoor location system is configured to determine a position of the mobile transceiver; and
spatially assigning the workpiece to the mobile transceiver assigned to the identified processing plan.

2. The method of claim 1 , wherein the processing plan-assistance-workpiece data set corresponding to the workpiece comprises at least one of
an image data set of the workpiece, or
a coding data set incorporated into the workpiece, and
wherein the assistance system is configured to perform at least one of:
detecting image data of the workpiece for generating the image data set for the workpiece, or
detecting a coding for generating the coding data set for the workpiece.

3. The method of claim 2 , wherein the coding data set comprises at least one of:
an RFID data set,
a bar coding data set, or
a magnetic coding data set.

4. The method of claim 1 , wherein the assistance system is configured to acquire the measurement-assistance-workpiece data set for the workpiece.

5. The method of claim 1 , wherein the assistance system is arranged on the machine tool and configured to detect the measurement-assistance-workpiece data sets for workpieces that are output from the machine tool and intended for further processing.

6. The method of claim 1 , wherein the machine tool is configured to:
receive the workpiece, and
deposit the workpiece in a depositing area assigned to the mobile transceiver.

7. The method of claim 1 , wherein the machine tool is configured to:
receive the mobile transceiver and the workpiece, and
deposit the mobile transceiver and the workpiece at a workpiece collection point.

8. The method of claim 1 , wherein the assistance system is configured to assist a sorting process of workpieces arranged spatially adjacent to each other on a sorting table,
wherein the assistance system includes a camera for imaging the sorting table and for generating a measurement-assistance-workpiece data set for at least one of the workpieces from a plurality of sorting image data sets, and
wherein the processing plan-assistance-workpiece data set comprises a processing plan-image data set on which manufacturing of the workpieces arranged spatially adjacent to each other is based.

9. The method of claim 8 , wherein workpieces to be assigned are generated with a flatbed machine tool according to the workpiece-specific processing plans and fed to the sorting table.

10. The method of claim 1 , wherein the manufacturing control system is configured to provide the mobile transceiver with a workpiece parameter for outputting information about the workpiece assigned to the mobile transceiver to support a manual operation of the spatially assigning the workpiece to the mobile transceiver.

11. The method of claim 1 , wherein the manufacturing control system is configured to control the mobile transceiver such that at least one of a processing parameter or a workpiece parameter is displayed on a display of the mobile transceiver.

12. The method of claim 1 , wherein the manufacturing control system is configured to assign a mobile transceiver data set of the mobile transceiver to the identified processing plan,
wherein the method comprises a mobile transceiver data-assignment process including at least one of:
a positioning of the mobile transceiver, a shaking of the mobile transceiver, or both, in a geometrically defined zone in the manufacturing hall,
an interacting with the manufacturing control system via a user interface,
an input of a reference number belonging to the identified processing plan into the manufacturing control system,
an automated or partially automated activation of the mobile transceiver via at least one sensor of the mobile transceiver having at least one of an input key on the mobile transceiver, an acceleration sensor, a position sensor, or a sound sensor, or
a linking of the mobile transceiver data set with a default object in the manufacturing control system.

13. The method of claim 12 , comprising:
in the mobile transceiver data-assignment process, loading at least part of the order information onto the mobile transceiver.

14. The method of claim 1 , wherein the assistance system has access to processing plan-assistance-workpiece data sets of the manufacturing control system, and
wherein comparing the measurement-assistance-workpiece data set generated for the workpiece to be assigned with the processing plan-assistance-workpiece data set corresponding to the workpiece to be assigned is performed by the assistance system.

15. The method of claim 1 , comprising:
assigning at least one tool or a workpiece collector to another mobile transceiver of the indoor location system based on comparing a measurement-assistance-tool data set for the tool or the workpiece collector with a processing plan-assistance-tool data set corresponding to the tool or the workpiece collector.

16. A manufacturing control system for controlling manufacturing processes of workpieces in a manufacturing hall, the manufacturing control system comprising:
an indoor location system configured to support manufacturing control of the manufacturing processes, the indoor location system comprising:
at least one stationary transceiver permanently installed in the manufacturing hall,
at least one mobile transceiver, and
wherein the stationary transceiver and the mobile transceiver are configured for transmitting and receiving electromagnetic signals,
wherein the indoor location system is configured to:
