Definitions
- the present invention relates to a device with rotating in operation or rotating surface, in particular roller or shell of a machine for producing a fibrous web, in particular paper web, with a plurality of arranged in or below the surface elements of a measuring device, in particular sensors.
- the invention has for its object to further improve the detection of the desired information.
- the elements are arranged offset in the direction of the surface and / or transversely thereto.
- the arrangement of the elements in the cross machine direction and in the machine direction offset from one another ensures that the desired information is recorded not only once per revolution of the surface, but depending on the number and distribution of the elements several times per revolution up to a quasi-continuous detection.
- the roll circumference is 3.14 m.
- a sensor diameter of 1 cm in known devices in the machine direction only all 3.14 m data are recorded, which data correspond to only 1 cm in the machine direction. That is, only 0.3% of the web is measured in the machine direction. Due to the staggered arrangement according to the invention, the data acquisition in the machine direction can be done more frequently. In immediate
- Connecting the sensors in the circumferential direction of the surface can even achieve continuous detection.
- Another advantage of the invention is that the data acquisition is simplified. With a large number of sensors, which are arranged next to one another in the cross-machine direction, the data must be recorded by all the sensors at the same time, since all sensors pass the measuring point, for example the roll nip, at the same time. In a staggered arrangement according to the present invention, however, it is sufficient to read the sensors substantially successively, as they also come successively through the interesting measuring point.
- the elements are distributed substantially over the entire machine width. As a result, the entire width, for example, of a paper web can be detected.
- the elements are arranged distributed in the circumferential direction over the entire surface. As a result, the information can be recorded in constant short intervals. Particularly preferred is the arrangement of the elements along at least one spiral line. This results in a uniform detection both in the cross machine direction and in the machine direction.
- the elements can also be arranged along two or more mutually parallel spiral lines. As a result, the time between two measurements can be shortened not only for the total width but at any point across the width of the machine.
- the elements of the measuring device may be formed by microwave sensors, optical sensors, ultrasonic sensors and temperature sensors, electromagnetic sensors, pressure or acceleration sensors or combinations thereof. Thus, the corresponding desired information can be obtained.
- a plurality of elements is provided, in particular more than 100 elements.
- a very dense collection of information can be achieved.
- the elements join each other substantially without gaps. As a result, a quasi-continuous detection of the desired information can be achieved.
- the elements interact with at least one radiation source arranged outside or inside the device, such as light, X-ray radiation, microwave radiation or radioactive radiation.
- a radiation source arranged outside the device such as light, X-ray radiation, microwave radiation or radioactive radiation.
- a transmission measurement takes place, in the case of a radiation source arranged inside the device, in particular a reflection measurement.
- a radiation source arranged inside the device in particular a reflection measurement.
- a reflection measurement can For this purpose can For example, be used measuring window, which are flush with the roll surface, these windows are translucent designed for the selected radiation.
- a measuring electronics located within the roller is provided, the Messdat ⁇ n are preferably transmitted wirelessly to a arranged outside the roller receiver.
- the invention further relates to a machine for producing or treating a fibrous web, in particular paper web with a device of the type described.
- the elements for determining the moisture or basis weight of the fibrous web, the composition of the fibrous web, for example, the filler content of the paper or the type of filler, the elasticity or hardness of the fibrous web or its thickness are formed. This allows important information to be obtained during operation in the machine.
- the invention relates to a method for producing or treating a fibrous web, in particular a paper web, in which a machine of the type mentioned is used.
- At least the energy required for operating the elements and / or the measuring electronics is generated and / or stored within the roller or on a non-rotating machine component.
- FIG. 1 shows a cross section through a pair of rollers of a machine according to the invention.
- FIG 2 is a perspective view of a roll according to the invention.
- the arrangement shown in Figure 1 comprises a roller 1 and a counter-roller 2, between which a first fabric 3, for example a felt or wire, and a second fabric 4, for example, a paper web are passed.
- a first fabric 3 for example a felt or wire
- a second fabric 4 for example, a paper web
- this may be a press arrangement of a paper machine.
- sensors 5 are provided for measuring certain data, such as pressure or humidity sensors.
- the sensors 5 are, as shown for example in Figure 2, along a spiral line in or below the shell 6 of the roller 1 is arranged. This achieves an approximately continuous acquisition of the data both in the circumferential direction of the roll 1, ie in the machine direction, and in the cross-machine direction.
- FIG. 2 shows a roller 1 with sensors 5 arranged along a spiral line.
- an external radiation source 7 is present, which interacts with the sensors 5.
- the sensors 5 for measuring the transmission of the radiation of the radiation source 7 through the jacket 6 of the roller 1 can be used.
- the sensors 5 are connected, for example wirelessly, to a measuring device, not shown here.
- the sensors are read out by the measuring device, wherein the sensors 5 can be read out one after the other or several sensors 5 at the same time. This is followed by the evaluation and optionally storage of the measured data.
