Definitions

  • the present invention relates to a method for controlling a container treatment system, in particular a beverage bottling system, which comprises at least one container treatment station for treating containers and an associated control device for controlling a container treatment process of the container treatment station, and a system comprising a container treatment plant.
  • the commissioning of such a system or a change of type takes place, for example, by an operator selecting a previously created type in the menu of an HMI module ("Human-Machine Interface Module").
  • Machine and process parameters are stored as a data record for the selected type, which are used to control the system.
  • the types can be managed centrally in an LMS (Line Management System) and transferred to the appropriate system if required.
  • the machine and process parameters for a desired type can be determined using algorithms, ranging from simple formulas to complex, rule-based calculation specifications, in order to be able to react flexibly to different process and environmental conditions.
  • type parameters When the machine is delivered, these type parameters are implemented in the control for each type and determine the later filling process.
  • Product-specific parameters e.g. Brix degree, CO 2 content, temperature, etc.
  • container-specific parameters e.g. bottle size, headspace size, finish cross-section, etc.
  • environmental parameters are taken into account, from which the corresponding machine and process parameters are then algorithmically determined for the customer.
  • the algorithms are currently being developed using laboratory measurements.
  • the type parameters implemented in the control of a plant are rigid, they do not react to changes in the product or in the environment, which can lead to filling problems.
  • the system can be parameterized manually by an operator, this requires highly specialized knowledge. Manual parameterization is made more difficult by the fact that the parameters often depend on one another. For example, an increase in the filling pressure results in a longer relief time. Incorrect operation/parameterization of the system can also cause damage and high costs.
  • One object of the invention is to improve the control of a container treatment system, preferably a beverage bottling system, in particular to simplify its parameterization.
  • the method according to the invention is used to control a container treatment plant.
  • the container treatment system comprises at least one container treatment station for treating containers and an associated control device for controlling a container treatment process of the container treatment station.
  • the control device can be part of the container treatment station or assigned to it directly or indirectly, for example if it is a higher-level system control.
  • the container treatment system can comprise a number of container treatment stations, so that a number of treatments or treatment steps can be carried out on the containers.
  • the container treatment plant can, for example, comprise one or more of the following container treatment stations: a device for producing containers; one Device for filling the containers with a filling product; a device for closing the containers, each with a container closure; a device for labeling the containers; a device for checking the quality of the containers; a buffer for the temporary buffering of containers and to compensate for any different processing/transport speeds between parts of the system; a packing device for packing the filled containers.
  • the container treatment plant is particularly preferably a beverage bottling plant, so that at least one of the container treatment stations is a filling device set up to introduce a filling product into the containers.
  • real-time process data is sent from the control device to a device for automatic process adjustment.
  • the device for automatic process adjustment is preferably an external device, i.e. in this case it is spatially separated from the container treatment plant.
  • the real-time process data can be obtained from appropriate sensors that monitor the container treatment process.
  • the real-time process data relate, for example, to temperatures, pressures, fill levels and the like.
  • Real-time process data may also be obtained through one or more cameras, referred to herein as a "sensor".

  • a container treatment system optimized in this way can be configured particularly flexibly and runs more stably overall.
  • the commissioning of the plant, a change of grade, a performance optimization, any troubleshooting, etc. is much faster and safer. This also reduces the training effort and causes fewer problems in the event of any personnel fluctuations on the part of the users of the container treatment system. Centralized optimization also helps reduce customer waste.

  • the adjustment comprises at least the determination of one or more process parameters by the device for automatic process adjustment and the writing of the determined process parameters into the control device.
  • the reading of the real-time process data can, but does not have to, take place in the same rhythm.
  • the process adjustment can be triggered by an event. Such an event can be triggered by the real-time process data, for example when a threshold value is exceeded or fallen below, or by a change in the machine configuration.
  • the control device preferably includes an HMI module (“Human-Machine-Interface-Module”) or is in communication with one.
  • the HMI module receives user input on the container handling process, creates user data from it and sends it to the facility for automatic process adjustment.

  • user inputs can be processed externally and are included in the operation of the system, so that the control devices, databases, Algorithms, etc. can be less complex on site, which not only reduces the costs of purchasing and operating such a container treatment system, but also contributes to the stability of the operation and the flexibility of the system.
  • the HMI module is preferably a portable device, for example a smartphone or tablet, so that the user can provide the desired information regardless of location.
  • the user data provided by the user or an operator can, for example, relate to the current status of the container treatment system, for example information about any rejects, ambient temperature, filling product quality, etc., and/or a desired status, for example when changing types.

  • the real-time process data sent to the device for automatic process adjustment and/or the user data received from the HMI module are also acquired by a development device.
  • the development device uses this data to develop calculation rules for calculating process parameters or configuration data.

These calculation rules receive as input, for example, product sizes (Brix degree, CO 2 content, product temperature, etc.), container format sizes (container volume, headspace volume, finish cross-section, container shape, container material, etc.), system performance and the like and calculate associated process parameters that can be selected as a configuration stored in the corresponding control device and/or can be used by the device for automatic process adjustment.
  • the calculation rules mentioned can be optimized by self-learning algorithms, so that the calculation rules and process parameters can be continuously optimized by the data feedback from the container treatment system from practice.
  • calculation rule includes simple calculation formulas up to complex algorithms.
  • the device for automatic process adjustment also receives configuration data from a configurator.
  • the configuration data determine, for example, the real-time process data to be used to determine the at least one process parameter and/or at least one optimization goal (filler performance, waste minimization, etc.).
  • the configuration data are taken into account by the device for automatic process adjustment to determine the process parameters.
  • the device for automatic process adjustment and thus indirectly the container treatment system can be configured quickly and easily without the necessary expertise having to be available on site.
  • the at least one container treatment station is preferably a filling device for filling containers with a filling product.
  • Beverages are particularly preferred as the filling product, for example water (still or carbonated), soft drinks, juices, beer, wine, milk products, mixed drinks and the like.
  • Filling devices are mechanically complex and their commissioning, configuration, etc. is usually hardly possible without in-depth specialist knowledge.
