项目摘要

Processing machines are used for automated production of commodities in mass demand. From economic point of view a constantly increasing production output of individualized products is required. Modern servo drives are often used to realize the individualization by enabling the flexible modification of trajectory values, even during operation of the machine (electronic cam disk). The production output can be increased by raising the working rate of the process. In practice, problems occur if at higher working rates requirements are no longer to be met, i.e. process instability, impact of surroundings, raising energy consumption or declining product quality. This limits the reachable working rate.The project focusses on the realization of higher working rates and thereby larger production output by shifting the limitation of the working rate. Commonly unused potentials of modern servo drives are utilized for the use in the context of processing machines.In the first years of the project, the basics of a solution approach based on three key issues were developed. It consists of (1) an approach to optimize trajectory values, wherein the limiting effects can be simulated and taken into account. For selected working rates trajectory values are optimized. They are put together to (2) a set of working rate-dependent trajectory values. On this way, selected working rate dependent characteristics can be modified. To use the potentials of the approach on the real machine, a (3) control system was developed, that enables the execution of the working rate-dependent trajectory values with high accuracy.With the new solution approach it is possible to realize alternative process solutions. This offers new potentials to increase the working rate compared with conventional processes. It has been demonstrated that it is possible to increase the working rate by using working-rate dependent optimized trajectory values, more potentials for development were shown. The solution approach was validated at the example of the intra-machine transportation of small-sized goods (e.g. chocolate bars).The continuation of the project applied here focusses on how the solution approach is usable for other types of production processes. Thereby, the first working content is the increase of the model base, the model validation and necessary control implementation. A second working content contains researches on how the solution approach is usable for other types of production processes by improving both, the optimization and the control framework. Finally, an experimental proof and demonstration will be performed.

加工机用于大批量需求的商品的自动化生产。从经济角度看，需要不断提高个性化产品的产量。现代伺服驱动器常用于实现个性化，使其能够灵活地修改轨迹值，甚至在机器运行期间（电子凸轮盘）。通过提高工艺的工作效率，可以提高生产产量。在实践中，如果不再满足更高的工作速率要求，则会出现问题，即过程不稳定，环境的影响，能源消耗增加或产品质量下降。这限制了可达的工作速率。本项目的重点是通过改变工作效率的限制，实现更高的工作效率，从而实现更大的产量。现代伺服驱动器通常未使用的潜力被用于加工机械的使用。在项目的头几年，开发了基于三个关键问题的解决方案方法的基础。它包括：(1)优化轨迹值的方法，其中可以模拟并考虑限制效应。对于选定的工作速率，轨迹值进行了优化。将它们放在一起得到(2)一组与工作速率相关的轨迹值。通过这种方式，可以修改所选的与工作速率相关的特性。为了在实际机器上利用该方法的潜力，开发了一个(3)控制系统，该系统能够以高精度执行与工作速率相关的轨迹值。有了新的解决方案方法，就有可能实现替代工艺解决方案。与传统工艺相比，这为提高生产率提供了新的潜力。实践证明，利用与开工率相关的优化轨迹值可以提高开工率，显示出更大的发展潜力。以小型货物（如巧克力棒）的机器内运输为例，验证了该解决方法的有效性。这里应用的项目的延续集中在解决方案方法如何可用于其他类型的生产过程。因此，第一个工作内容是增加模型库，模型验证和必要的控制实现。第二个工作内容包括通过改进优化和控制框架，研究如何将解决方法用于其他类型的生产过程。最后，进行实验验证和演示。
