Description

[0001] Method for controlling a container treatment plant and container treatment plant for carrying out the method

[0002] The invention relates to a method for controlling a container treatment plant and a container treatment plant for carrying out the method according to the independent claims.

[0003] State of the art

[0004] It is well known that the containers to be treated are transported between the individual machines in a container processing plant using bulk transport. In the bulk transport system, there are jam switches that indirectly indicate the operating status of the individual machines; they can detect malfunctions or underperformance. There is generally no signal exchange with direct control between the machines and the bulk transport system. Therefore, the individual machines cannot be controlled comprehensively.

[0005] Task

[0006] The object of the invention is to provide a method for controlling a container treatment plant and a container treatment plant for carrying out the method in order to be able to comprehensively and efficiently control a decrease in performance or an increase in performance in one or more of the machines for operating the container treatment plant.

[0007] Solution

[0008] The object is achieved by the method for controlling a container treatment plant and the container treatment plant for carrying out the method according to the independent claims. Further embodiments are disclosed in the subclaims.

[0009] The method according to the invention for controlling a container treatment plant comprising a plurality of machines each connected by means of conveyors and / or buffer devices and / or buffer tables, which are electronically coupled, comprises operating the container treatment plant and comprises for each magazine during operation:

[0010] - provision of first processed data by the individual transporters and / or buffer devices and / or buffer tables, wherein the first processed data comprise a first current performance and first framework conditions within which the individual transporters can be operated for each magazine,

[0011] - providing second processed data by each individual machine, wherein the second processed data comprises a second current performance and second framework conditions within which the individual machines can be controlled for each magazine, - tapping the first processed data and the second processed data by a control device,

[0012] - controlling the individual machines for each magazine by means of the control device based on the first processed data and / or the second processed data.

[0013] The terms "first," "second," etc., and similar terms here and below serve only to distinguish between the two. If an explicit order is intended, this will be explicitly stated in the context.

[0014] Electronically coupled can mean that between the interlocked machines the containers are conveyed in a single-line transport from one machine to the next.

[0015] Processing of the data may include evaluating jam switches with regard to switching times, switching cycles and / or evaluating camera images with software and / or using, among other things, Kl, and / or light pulses from light barriers for container counting.

[0016] The control device may be a single control device.

[0017] For the control based on the first processed data and / or the second processed data, a minimization and / or maximization algorithm can be used, which can, for example, include avoiding an unwanted stop of one or more machines and / or one or more conveyors and / or one or more buffer devices and / or one or more buffer tables, even if the control may temporarily reduce the overall performance of the container handling system.

[0018] By controlling by means of the control device based on the first processed data and / or the second processed data, it is possible to react comprehensively to changes in the performance of conveyors and / or buffer devices and / or buffer tables and / or machines and to adapt the entire container handling system accordingly.

[0019] The first and second processed data can all be provided in a single higher-level data layer.

[0020] The control may include controlling the conveyors and / or buffer devices and / or buffer tables using sensors incorporated in the conveyors and / or buffer devices and / or buffer tables. The sensors may include jam switches, optical units such as cameras and image evaluation, etc. The control may include transmitting information from the individual conveyors and / or buffer devices and / or buffer tables to the control device and correspondingly controlling the individual machines using the control device. Such control may include changes to process parameters.

[0021] The regulation can be triggered by a drop in performance and / or a targeted performance parameterization on a machine in the container handling system. For simplicity, we will refer to "drop in performance" below.

[0022] The percentage figures used below, for example regarding performance, are given as examples and may vary depending on the characteristics and situation.

[0023] In the event of an emergency stop of the container handling system, the control may include direct control of the conveyors and / or buffer devices and / or buffer tables.

[0024] In the event of an emergency stop of the container treatment plant, the control may comprise transmitting information from the individual machines to the control device and controlling the individual machines accordingly by means of the control device.

[0025] If the container treatment plant successively comprises a filling and closing device, a first conveyor, a pasteurizer comprising a pasteurization area and a buffer area, a second conveyor and a packer, the control can comprise the following target image: operating the filling and closing device at a nominal power, operating the first conveyor at the nominal power, operating the pasteurization area at the nominal power, occupancy of the buffer area less than, for example, 10%, operating the second conveyor at the nominal power and operating the packer at the nominal power.

[0026] These settings can correspond to the target image of the ideal production situation. For example, maximum output, optimal buffer utilization to absorb downstream disruptions, and / or optimal operation of the container treatment plant.

[0027] If the performance of the filling and closing device drops to 70% of its rated capacity, the control can include the following target scenario: a linear reduction in the rated capacity of the first conveyor to, for example, 70%, a linear reduction in the rated capacity of the pasteurization area to, for example, 70%, an occupancy of the buffer area of ​​less than, for example, 10%, a linear reduction in the rated capacity of the second conveyor to, for example, 70%, and a linear reduction in the rated capacity of the packer to, for example, 70%. This setting can reduce the performance of the filler up to the packer while maintaining optimal buffer occupancy, for example, in response to a palletizer malfunction or process problems in individual units / machines of the container handling system.

[0028] When the filling and closing device stops, the control can include the following target image: a linear reduction of the rated power of the first conveyor to 0%, a linear reduction of the rated power of the pasteurization area to 0%, a stop of the buffer area, a linear reduction of the rated power of the second conveyor to 0% and a linear reduction of the rated power of the packer to 0%.

[0029] This setting can restore the target image when production is stopped after a filler stop, which can occur after a cascade-like emptying or stopping of the machines.

[0030] If the performance of the pasteurization area drops to, for example, 70% of the nominal performance, the control can include the following target image: a linear reduction in the nominal performance of the filling and closing device to, for example, 70%, a linear reduction in the nominal performance of the first conveyor to, for example, 70%, an occupancy of the buffer area of ​​less than, for example, 10%, a linear reduction in the nominal performance of the second conveyor to, for example, 70% and a linear reduction in the nominal performance of the packer to, for example, 70%.

[0031] For example, the pasteurizer can be operated at reduced power, for example in response to a reduced heat supply.

[0032] When the pasteurization area is stopped, the control can include the following target image: a linear reduction of the rated power of the filling and closing device to 0%, a linear reduction of the rated power of the first conveyor to 0%, a stop of the buffer area, a linear reduction of the rated power of the second conveyor to 0% and a linear reduction of the rated power of the packer to 0%.

[0033] If the packer's performance drops to, for example, 70% of the nominal performance, the control can include the following target image: operating the filling and closing device at the nominal performance, operating the first conveyor at the nominal performance, operating the pasteurization area at the nominal performance, increasing the occupancy of the buffer area, a linear reduction in the nominal performance of the second conveyor to, for example, 70%, when the buffer area has reached maximum occupancy, then a linear reduction in the nominal performance of the filling and closing device to, for example, 70%, a linear reduction in the nominal performance of the first conveyor to, for example, 70% and a linear reduction in the nominal performance of the pasteurization area to, for example, 70%.

[0034] If the packer's performance is increased to, for example, 120% of the nominal performance, the control can include the following target image: operating the filling and closing device at the nominal performance, operating the first conveyor at the nominal performance, operating the pasteurization area at the nominal performance, reducing the occupancy of the buffer area and a linear increase in the nominal performance of the second conveyor to, for example, 120%.

[0035] When the packer is stopped, the control can include the following target image: operating the filling and closing device at the rated power, operating the first conveyor at the rated power, operating the pasteurization area at the rated power, increasing the occupancy of the buffer area, a linear reduction of the rated power of the second conveyor to 0% when the buffer area has reached maximum occupancy, then a linear reduction of the rated power of the filling and closing device to 0%, a linear reduction of the rated power of the first conveyor to 0% and a stop of the buffer area.

[0036] The first and / or second processed data may include information about acceleration and deceleration ramps and / or information about the start of a predictable power adjustment with a timestamp and / or information about the end of a standstill that has occurred with a timestamp. For example, information about the start of a predictable power adjustment may further include a time period indicating when one of the machines stops.

[0037] The start-up and stop ramps can, for example, use a mathematical function to indicate how the power can be increased or decreased during control.

[0038] A timestamp can be a time of day. For example, if a foreseeable performance adjustment begins, the timestamp can specify the time at which the performance adjustment should begin. For example, if a downtime has occurred, the timestamp can specify the time at which the downtime will end. This can be the case, for example, for a downtime during which labels are being refilled. A foreseeable performance adjustment that can result in a reduction in performance can occur due to a pallet change on an empty can pusher, a pallet change on a palletizer, or the refilling of film on a wrapper. A foreseeable performance adjustment can occur when a certain glue temperature needs to be reached on a labeling machine.

[0039] A container treatment plant is provided which comprises a plurality of machines each connected by means of conveyors and / or buffer devices and / or buffer tables which are electronically coupled, the container treatment plant being adapted to carry out the method as described above or further below.

[0040] The container handling plant may comprise the conveyors and / or buffer devices and / or buffer tables and machines already mentioned in connection with the process.

[0041] The container treatment system may include a control device. Alternatively, the control device may be provided separately from the container treatment system.

[0042] The container treatment plant may further comprise, in sequence, a filling and closing device, a first conveyor, a pasteurizer comprising a pasteurization area and a buffer area, a second conveyor and a packer.

[0043] The first and second conveyors can be designed for single-strand transport of containers.

[0044] The container treatment plant may further comprise a depalletizer arranged upstream of the filling and closing device, a further conveyor arranged downstream of the depalletizer, an additional conveyor arranged downstream of the packer and a palletizer arranged downstream of the additional conveyor.

[0045] The further and additional transporter can be trained for single-line transport of containers.

[0046] Short character description

[0047] The attached figures represent aspects and / or embodiments of the invention by way of example for better understanding and illustration. It shows:

[0048] Figure 1 shows schematically a container treatment plant,

[0049] Figure 2 shows an embodiment for controlling a start-up or shut-down process of the container treatment plant,

[0050] Figure 3 shows a further embodiment for controlling a start-up or shut-down process of the container treatment plant, Figure 4 shows an embodiment for controlling the container treatment plant in the event of an emergency stop and

[0051] Figure 5 shows a further embodiment for controlling the container treatment system in the event of an emergency stop.

[0052] Detailed character description

[0053] Figure 1 schematically shows a container treatment plant 1, which here comprises a depalletizer 2, followed by a first conveyor 3, followed by a filling and closing device 4, followed by a second conveyor 5, followed by a pasteurizer 6 comprising a pasteurization area 7 with adjoining buffer area 8, followed by a third conveyor 9, followed by a packer 10, followed by a fourth conveyor 11 and followed by a palletizer 12.

[0054] The terms "first," "second," etc., and similar terms here and below serve only to distinguish between the two. If an explicit order is intended, this will be explicitly stated in the context.

[0055] The depalletizer 2, the filling and closing device 4, the pasteurizer 6, the packer 10, and the palletizer 12 represent machines of the container handling system 1. The machines are electronically linked.

[0056] The depalletizer 2 may include a pusher (not shown), which may be motor-assisted, for example, for pushing the containers off a pallet on which they can be delivered. This may be provided, for example, for cans that are to be processed in the container processing system 1.

[0057] For the method for controlling the container treatment system 1, first processed data 13 from the depalletizer 2, second processed data 14 from the first conveyor 3, third processed data 15 from the filling and closing device 4, fourth processed data 16 from the second conveyor 5, fifth processed data 17 from the pasteurizer 6, sixth processed data 18 from the third conveyor 9, seventh processed data 19 from the packer 10, eighth processed data 20 from the fourth conveyor 11 and ninth processed data 21 from the palletizer 12 are provided for each magazine.

[0058] The processed data 13-21 can each include a current performance and framework conditions within which regulation is possible for each period. The current performance can therefore indicate a decrease in performance, an increase in performance, a constant performance, or a performance of 0%, which can mean a standstill. In addition, the processed data 13-21 can include information on start-up and shutdown ramps (how an increase or decrease in performance can occur) and / or information on the start of a foreseeable performance adjustment with a time stamp and / or information on an end in the event of a standstill that has occurred with a time stamp. Information on the start of a foreseeable performance adjustment can, for example, include a time period that indicates when the filling and closing device 4 stops (0% performance) or when the pasteurization area 7 stops (0% performance) or when the packer 10 stops (0% performance).

[0059] A timestamp can be a time of day. For example, if a predictable power adjustment is about to begin, the timestamp can indicate the time at which the power adjustment should begin. For example, if a downtime has occurred, the timestamp can indicate the time at which the downtime will end. This could be the case, for example, for a downtime during which labels are being refilled.

[0060] The processed data 13-21 can all be provided in a single higher-level data layer.

[0061] A control device 22 is configured to access the various processed data 13-21. The control device 22 can be included in the container treatment system 1 or, as shown in Figure 1, can be provided separately from the container treatment system 1.

[0062] The individual conveyors 14, 16, 18, 20 and / or the individual machines 2, 4, 6, 10, 12 can be controlled by means of the control device 22 based on the respective processed data.

[0063] For example, the first processed data 13 can indicate that, with a current output of 100% of the depalletizer 2, control can be effected in a range of 70%-100%. For example, the third processed data 15 can indicate that, with a current output of 100% of the filling and closing device 4, control can be effected in a range of 20%-100%. For example, the fifth processed data 17 can indicate that, with a current output of 100% of the pasteurization area 7, control can be effected in a range of 1%-100%. For example, the seventh processed data 19 can indicate that, with a current output of 100% of the packer 10, control can be effected in a range of 50%-100%. For example, the ninth processed data 21 may indicate that with a current performance of 100% of the palletizer 12, control can be effected in a range of 1%-100%.In order to explain in more detail the method for controlling the container treatment plant 1, which comprises several machines 2, 4, 6, 10, 12, each connected by means of conveyors 3, 5, 9, 11, which are electronically coupled, the following numerical examples, which are not to be seen as a limitation, serve.

[0064] During normal operation of the container processing system 1, the filling and closing device 4, the second conveyor 5, the pasteurization area 7, the third conveyor 9, and the packer 10 can each be operated at a nominal capacity, in this case 100%. The buffer area 8 can have a minimum occupancy, which can be less than 10%, for example.

[0065] If the capacity of the filling and closing device 4 is reduced from 100% to 70%, the control device 22 can accordingly linearly reduce the capacity of the second conveyor 5 to 70%, the capacity of the pasteurization area 7 to 70%, the capacity of the third conveyor 9 to 70%, and the capacity of the packer 10 to 70%. The previously mentioned minimum occupancy of the buffer area 8 can be maintained.

[0066] When the filling and closing device 4 stops, the control device 22 can accordingly linearly reduce the performance of the second conveyor 5 to 0%, linearly reduce the performance of the pasteurization area 7 to 0%, linearly reduce the performance of the buffer area to 0%, linearly reduce the performance of the third conveyor 9 to 0% and linearly reduce the performance of the packer 10 to 0%.

[0067] If the capacity of the pasteurization area 7 is reduced to 70%, the control device 22 can accordingly linearly reduce the capacity of the filling and closing device 4 to 70%, the capacity of the second conveyor 5 to 70%, the capacity of the third conveyor 9 to 70%, and the capacity of the packer to 70%. The aforementioned minimum occupancy of the buffer area 8 can be maintained.

[0068] When the pasteurization area 7 is stopped, the control device 22 can accordingly linearly reduce the performance of the filling and closing device 4 to 0%, linearly reduce the performance of the second conveyor 5 to 0%, linearly reduce the performance of the buffer area to 0%, linearly reduce the performance of the third conveyor 9 to 0% and linearly reduce the performance of the packer 10 to 0%.

[0069] If the capacity of packer 10 is reduced to 70%, the increase in occupancy of buffer area 8 must be taken into account. Initially, filling and closing device 4 continues to operate at its rated capacity, second conveyor 5 continues to operate at its rated capacity, and pasteurization area 7 continues to operate at its rated capacity. The control device 22 can be used to linearly reduce the capacity of the third conveyor to 70%. This results in an increase in occupancy of buffer area 8. When buffer area 8 has reached maximum occupancy, the control device 22 also linearly reduces the capacity of filling and closing device 4 to 70%, the capacity of the second conveyor 5 to 70%, and the capacity of pasteurization area 7 to 70%.

[0070] In order to subsequently reduce the occupancy of the buffer area 8 (or to generally reduce the occupancy of the buffer area 8, for example, during a planned product change), the power of the packer 10 can be increased to 120% by means of the control device 22. The control device 22 linearly increases the power of the filling and closing device 4 to the nominal power, linearly increases the power of the second conveyor 5 to the nominal power, linearly increases the power of the pasteurization area 8 to the nominal power, and linearly increases the power of the third conveyor 9 to 120%.

[0071] Even when the packer 10 is stopped, the increase in occupancy of the buffer area 8 must be taken into account. The filling and closing device 4, the second conveyor 5, and the pasteurization area 7 are each operated at their nominal power, and the power of the third conveyor is linearly reduced to 0% by means of the control device 22. This increases the occupancy of the buffer area 8. When the buffer area 8 has reached maximum occupancy, the control device 22 then linearly reduces the power of the filling and closing device 4 to 0%, the power of the second conveyor 5 to 0%, and the power of the pasteurization area 7 to 0%.

[0072] Figure 2 schematically illustrates an embodiment of how, during a start-up or shut-down process of the container treatment plant 1, the container treatment plant 1 can be controlled by means of a conveyor control 23 via a sensor system included in the conveyors 3, 5, 9, 11. The performance of the conveyors 3, 5, 9, 11 can influence a machine 2, 4, 6, 10, 12 arranged directly upstream (for removing containers from this machine) and a machine 2, 4, 6, 10, 12 arranged directly downstream (for feeding containers to this machine), as well as indirectly on machines 2, 4, 6, 10, 12 arranged further upstream or downstream.

[0073] Figure 3 schematically illustrates a further embodiment of how, during a start-up or shut-down process of the container treatment plant 1, the container treatment plant 1 can be controlled by transmitting information through the individual conveyors 3, 5, 9, 11 to the control device 22 and by correspondingly controlling the individual machines 2, 4, 6, 10, 12 by means of the control device 22.

[0074] Figure 4 schematically illustrates an embodiment of how, in the event of an emergency stop of the container treatment system 1, the container treatment system 1 can be controlled by directly controlling the conveyors 3, 5, 9, 11. In addition, possible dependencies 24-33 between conveyors 3, 5, 9, 11 and machines 2, 4, 7, 8, 10, 12 or between different machines 4, 7, 8, 10 are indicated, which may need to be considered when controlling in the event of an emergency stop.

[0075] Figure 5 schematically illustrates a further embodiment of how, in the event of an emergency stop of the container treatment plant 1, the container treatment plant 1 can be controlled by transmitting information from the individual machines 2, 4, 6, 10, 12 to the control device 22 and by correspondingly controlling the individual machines 2, 4, 6, 10, 12 by means of the control device 22. Furthermore, the possible dependencies 24-33 between conveyors 3, 5, 9, 11 and machines 2, 4, 7, 8, 10, 12 or between different machines 4, 7, 8, 10 are also indicated here, which may need to be taken into account when controlling in the event of an emergency stop.
