Advantages of the invention

The production plant according to the invention for carrying out a production process in a plant area of the production plant, with a safety unit, wherein the safety unit is designed to monitor the plant area and to stop and / or interrupt the production process as a function of the monitoring and / or to slow down, the production plant At least one functional module for carrying out at least one production step of the manufacturing process and at least one evaluation unit, wherein the evaluation unit is designed to determine an absolute position of the functional module in the system area based on environmental data generated by a sensor unit, has the advantage that safe operation of modular applicable functional modules is ensured without each of the function modules must have corresponding safety devices to protect the user. This is achieved by including all components required for safe operational operation, in particular with regard to machine safety, in the basic cell. These include security elements, such as separating guards and / or light grids and / or a safety controller and / or the control technology and / or robot with a sensor skin for detecting the approach of objects.

It is advantageous that the sensor unit is designed as a camera and / or as a laser sensor, for example as a LIDAR unit. It is particularly advantageous that the sensor unit is based on a laser-based measuring method. Such sensor units have the advantage that they are cost-effective on the one hand due to their broad use outside of production technology. At the same time, these sensor units contribute to the fact that a high measuring accuracy can be achieved. Advantageously, the laser sensor is designed for transit time measurements between infrared flashes and laser lines. With a brief flash, infrared LEDs signal the start time for a first laser, which scans the room to be monitored from one side to the other. A second brief illumination of the infrared LEDs signals the starting time of the second laser so that the second laser scans the space to be monitored from top to bottom. Such a laser sensor achieves measurement accuracies of better than 1 mm.

It is particularly advantageous if the sensor unit is arranged at the production facility, spatially spaced from the functional module such that the sensor unit detects at least a part of the installation area, preferably the entire installation area. It is particularly advantageous that the flat plate of the manufacturing plant is only partially monitored with the sensor unit, while the remaining part can be used otherwise, but not by the function modules. However, it is particularly advantageous that the environmental data generated by the sensor unit, on the one hand, will be used to determine the positions of the functional modules and, on the other hand, be used for monitoring the system area during the execution of the manufacturing process.

It is particularly advantageous that the sensor unit is arranged on the production line such that the sensor unit detects the entire system area. In conjunction with the evaluation unit, this contributes to the functional modules and / or workpiece holders being able to be measured within the basic cell with a measurement accuracy better than 0.1 mm in at least 3 degrees of freedom. This has the overall advantage that the facility can be set up faster because it saves the operator the manual, time-consuming and error-prone teaching of poses.

It is advantageous that the functional module comprises a mounting surface, wherein for fixing the functional module in the system area, the mounting surface contacts the system area surface in a contact surface, wherein the sensor unit is arranged on the functional module such that the sensor unit at at the contact surface fixed functional module at least part of the contact surface detected. In conjunction with the use of markings on the placement surface of the function module, this allows a particularly accurate determination of the absolute position of the function module.

It is particularly advantageous that the control unit is designed, a desired position of the functional module in the system area depending on the workpiece to be manufactured and the Function description of the at least one manufacturing step of the function module to determine and output the specific target position of the function module via an output unit. This functionality supports and assists the user in setting up the manufacturing line so that setup can be done faster and with less likelihood of setup errors.

It is also advantageous that the control unit is designed to detect a change in position of the functional module in the installation area and to adapt the production process to the position change as a function of the detected change in position of the function module. On the one hand, this has the advantage that changes in the structure are automatically detected. It is particularly advantageous that the manufacturing process is automatically adapted to the change in position without the need for manual intervention by a user.

It is particularly advantageous that, in addition to the at least one functional module, the production system comprises at least one handling unit fixedly mounted in the installation area. Most manufacturing processes take place in several consecutive production steps. In addition, a feeding and / or discharge of workpiece blanks to be machined and finished workpieces is carried out regularly. A universally usable handling unit, which is fixed in the system area, can provide these functions quickly and easily. In addition, the handling unit fixedly mounted in the installation area has the advantage that the position and the working area of the handling unit are known in advance and therefore no longer has to be determined.

In summary, the manufacturing facility and method of performing a manufacturing process in a plant area of a manufacturing facility has the advantage of assisting the user in programming, commissioning, and executing automated processes. This contributes to economical automation even in small lots or lot sizes by requiring little user training because the manufacturing process can be set up by configuring instead of programming at the code level, as well as reuse functional modules and process parameters. In addition, the automation contributes to a reproducible quality of the manufactured workpieces. It is particularly advantageous that positions of function modules are detected automatically and sequence programs stored in the function modules are parameterized quickly, simply and automatically in order to then execute these sequence programs. The particular advantage of the production system according to the invention and of the working method is that a (partially) automated production without programming knowledge is possible.

Incidentally, the advantages described in relation to the production facility also apply accordingly to the working process for carrying out a production process.

Further advantages will become apparent from the following description of embodiments with reference to the figures and from the dependent claims.
