Definitions
- the present invention relates to a method and device for monitoring and storing the properties of various components of a paper/board or pulp and finishing/converting machine and the changes taking place in them and/or the ambient conditions and the changes taking place in them, and for transmitting this data to the control unit of the paper/board or pulp or finishing/converting machine and/or to a separate data processing system.
- control unit refers to a control unit at any hierarchical level of the paper/board or pulp and finishing/converting machine, that is, it may be, for example, the machine's central control unit or one of the control units in the machine's decentralised automation system.
- Paper/board or pulp and finishing/converting machines comprise a large number of different components which have to be replaced and serviced due to, for example, wear and breakdown. For this reason, instead of using the components proper, temporary components have to be used, components have to be removed from the machine for the duration of servicing the component in question, or an old component has to be replaced by a new one. Often, the properties of temporary, serviced or new components which have an effect on the control values of the machine, do not correspond to the properties of the original component. Such components are, for example, the rolls of the machines mentioned above.
- the roll is usually replaced by a spare roll, in which case the properties of the spare roll do not correspond fully to the properties of the original roll, such as weight, mantle diameter, surface material and deflection.
- the data on the properties of the components such as data on the diameter of the roll and other dimensional data
- the data on the properties of a component are written by hand on the surface of the components, for example, with chalk, or on a separate piece of paper which is attached to the surface of the component, which means that the data on the properties of a component may be lost, for example, during storage or transportation of the component. In such a case, the properties of the component in question have to be measured or determined again.
- the component may be subjected to, for example, intensive accelerations and impacts.
- the component is also often subjected to changes in the ambient conditions, such as temperature and humidity.
- the properties of, for example, the surface materials of rolls, such as polyurethane, change when subjected to temperature changes. Very often these changes are not noticed until they manifest themselves as disadvantageous changes in the quality of the end product, such as changes in the quality of paper in paper machines.
- Monitoring and storing the changes taking place in the properties of different components and the ambient conditions and the changes taking place in them per component, for example, during the production run, storage or transportation is almost impossible by using known methods and devices.
- the aim of the present invention is to achieve a method and device for eliminating, or at least substantially reducing, the foregoing disadvantages.
- the method relating to the invention is characterised mainly in that in the component is arranged a memory unit accompanying it, in which can be written or which can be read electrically, by magnetisation or optically, in which memory unit are stored at least those properties of the components which affect the control values of a paper/board or pulp or finishing/converting machine in connection with the manufacture or servicing of a component in question, before the component is taken for installation into a paper/board or pulp or finishing/converting machine, or taken to be stored for later use, and that data transmission means are arranged for transmitting the data stored in the memory unit to the control unit of a paper/board or pulp or finishing/converting machine and/or a separate data processing system.
- the device relating to the invention is, on the other hand, characterised mainly in that in the component is arranged a memory unit accompanying it, in which can be written or which can be read electrically, by magnetisation or optically, in which memory unit can be stored at least those properties of the components which affect the control values of a paper/board or pulp or finishing/converting machine in connection with the manufacture or servicing of a component in question, before the component is taken for installation into a paper/board or pulp or finishing/converting machine, or taken to be stored for later use, and that data transmission means have been arranged for transmitting the data stored in the memory unit to the control unit of a paper/board or pulp or finishing/converting machine and/or a separate data processing system.
- Figure 1 shows diagrammatically a paper machine roll with a read/write memory unit.
- Figure 2 shows diagrammatically a roll in a paper machine, which roll has a read/write memory unit.
- Figure 1 shows diagrammatically a paper machine roll 1 and the main principles for monitoring and storing the properties A of the roll 1 , the changes taking place in them, and the ambient conditions and the changes taking place in them.
- Roll 1 is, for example, a calender roll, the mantle 5 of which is coated with a polymer.
- a read/write memory unit 2 in which are stored, in connection with the manufacture or servicing of the roll 1 , those properties A of the roll 1 which affect the control values of the paper machine 20.
- Such properties A of the roll 1 are, for example, its diameter, weight, the deflection of the mantle 5, the composition of the surface material of the mantle 5, surface roughness, hours of operation of the roll, and the procedures carried out during the servicing of the roll 1 , such as grindings.
- the data on the properties A of the roll 1 are stored in the memory unit 2, for example, by means of a separate data processing system 4, such as a PC, located at the service point, from which the data in question on the properties A of the roll 1 are transmitted by the data transmission means 3a to the memory unit 2. Furthermore, the properties A stored in the memory unit 2 can be read in the desired form, for example numerically, by transmitting the data on the properties A of the roll 1 by means of data transmission means 3b to a separate data processing system 4.
- a separate data processing system 4 such as a PC
- the sensors 6, 7, 8 observing the state of the roll 1 and the ambience are in contact with the memory unit 2.
- the sensors 6 are, for example, piezoelectric power sensors arranged in conjunction with the coating of the roll 1 mantle 5, by means of which sensors is measured the nip force exerted on the roll 1 mantle 5, which force is generated in a paper machine between a roll 1 and a backing roll 1 (not shown).
- Sensor 7 is a temperature sensor and sensor 8 an acceleration transducer.
- Sensors 6, 7, 8 and any other sensors observing the properties A of the roll 1 monitor the changes taking place in them.
- the temperature sensor 7 detects the change, which is stored in the memory unit 2 in contact with the temperature sensor 7.
- the Acceleration transducer 8 detects any impacts that take place during the transfer, which may have a disadvantageous effect on the operating characteristics of the roll 1. The observation of the impact is also stored in the memory unit 2 in contact with the Acceleration transducer 8.
- the properties A of the component and any changes in the properties of the component, ambient conditions and changes B in the ambient conditions are stored in the memory unit 2.
- data transmission means 9a, 9b ( Figure 2).
- the above-mentioned data stored in the memory unit 2 are transmitted to the control unit 10 where they can be read and processed. If necessary, the data can be transmitted from the control unit 10 to the memory unit 2.
- the data can be read and processed in a corresponding manner also by means of a separate data processing system 4.
- the control unit 10 and the separate data processing system 4 are preferably also connected continuously or temporarily with each other by means of data transmission means 11a, 11b.
- the foregoing data are transmitted by means of the data transmission means 11a from the data processing system 4 to the control unit 10 and by means of data transmission means 11b from the control unit 10 to the data processing system 4.
- the component preferably also incorporates sensors observing the operating conditions.
- these sensors are thus, for example, piezoelectric sensors 6 arranged in conjunction with the roll mantle 5 and observing the nip force.
- the power sensors are also in contact with the memory unit 2, whereby the changes B in the nip force observed by the power sensors 6 are stored in the memory unit 2.
- Other operating conditions may also be observed by corresponding provision of sensors. It is, for example, useful to observe the operating temperature.
- the properties of the roll 1 (or other component) and its ambient conditions change often, and thus also much data B relating to these changes is stored in the memory unit 2, which means that its memory capacity does not necessarily suffice to store all the data B.
- the memory unit 2 then contains preferably a certain amount of data stored at predetermined intervals from each sensor 6, 7, 8, the data forming for each sensor 6, 7, 8 an essential, continuous "history of events" corresponding to a certain time period.
- the very oldest stored data is deleted at specific intervals.
