Definitions
- the invention relates to a method and a device for monitoring a moving web, wherein at least part of the width of the web is detected.
- DE 101 23 870 discloses a device for the automatic monitoring of, in particular, textile fabrics or fabric webs, this device being arranged directly on the production machine of the fabric or fabric web.
- this device several very small sensors are arranged with direct contact to the fabric.
- the device is attached to the production machine via a vibration-damping suspension, so that the machine movement is only transmitted via the textile fabric.
- the invention as characterized in the patent claims, therefore achieves the object of creating a method and a device for monitoring moving material webs with at least one sensor bar, which largely as far as possible the geometric relationships between the individual elements from which the material web is constructed also maintained in the image of the web.
- a sensor bar for scanning the web in the direction of the width of the web can be arranged at an acute angle, so that information about a property associated with the movement of the web can be derived from the signal of the same sensor bar can be.
- An image of the material web in the part in question is also to be created from the same signal, this image being built up line by line or in sections. But one can also align the sensor strips perpendicular to the movement of the web and • arranging at least one further sensor for detecting a property in connection with the movement of the web property in the areas of this part of the web.
- Such a further sensor is preferably an optical sensor with one or more image lines.
- this method and this device serve to detect errors in the material web, such as deviations in structure, color or patterns on the material web, to report them or to trigger further actions such as, for example, the stoppage of the material web.
- a particularly important property, which is connected with the movement of the material web is its instantaneous speed, which applies especially when an image of a section of the material web is recorded or created.
- the advantages achieved by the invention are to be seen in particular in the fact that from the signals of the sensor strip and the possibly additional signals which another sensor emits, the geometric relationships between individual elements of the web, such as between adjacent warp and weft threads in a fabric, can also be maintained in the image of the tissue that is generated from signals from the sensor bar. For example, it is easier and also safer to clean these geometric relationships based on an instantaneous speed instead of an average speed.
- the further sensor can also only detect distances by, for example, emitting a pulse according to predetermined, covered distances or by clocking from the outside and outputting the distances covered by the material web per cycle interval.
- FIG. 1 shows a first schematic illustration of an arrangement according to the invention of sensor strips and further sensors in front of a web
- FIGS. 2, 3, 5 and 6 each show a further arrangement of sensor strips
- FIG. 4 shows an arrangement according to FIG. 1 with further elements 7 shows a path-time diagram for a material web
- FIG. 8 shows a schematic representation of the geometric relationships when scanning a material web
- FIG. 9 shows a signal as may be generated by sensor strips according to FIG. 2.
- Fig. 1 shows in front of a web 1, the edges of which are indicated by lines 2 and 3, sensor strips 4a, 4b, 4c, which are designed identically to one another, and further sensors 5a, 5b, 5c, which detect a property of the web, which is related to the movement of the web 1.
- properties are, for example, the ' path covered by the web 1, the instantaneous speed of the web 1 in the direction in which it is moving, the acceleration at
- Each sensor bar 4 and each further sensor 5 are arranged such that they sweep over part of the web 1 when it moves in the direction of an arrow 6 (FIG. 3).
- Such parts 7a, 7b, 7c of the web 1 are delimited in FIG. 1 by further lines 8a, 8b within the web 1.
- the sensor strips 4a and 4c, as well as any further sensor strips that are not shown here, form a first sensor line 20, while the sensor strip 4b, alone or together with possible further sensor strips, which are not shown here, forms a second sensor line 21 that is parallel to the first sensor line 20 runs.
- the sensor strips 4a and 4c from the first sensor line 20 and the sensor strip 4b from the adjacent second sensor line 21 partially overlap when viewed in the direction of the movement of the material web.
- FIG. 2 shows a further arrangement of sensor strips 9a, 9b, 9c and possible further sensors 10a, 10b, 10c, the sensor strips 9 being inclined by an angle ⁇ , which here is, for example, 15 °, against a line 11 which is in FIG Direction of the width of the web 1, perpendicular to the direction of arrow 6.
- FIG. 3 shows an arrangement of sensor strips 12a, 12b, 12c according to FIG. 1, but with further sensors 13a and 13b, which can each be assigned to two sensor strips, and further sensors 13c and 13d, which are assigned to only one sensor strip here.
- the further sensors 13a and 13b are arranged in the edge regions of the sensor strips 12. It should be noted here that the arrangements shown with three sensor strips are chosen arbitrarily and are only to be understood as examples. Of course, any number of sensor strips 12 can be arranged, the greater the width, the more sensor strips in order to detect the entire width of the web 1. This applies to all of the arrangements shown in FIGS. 1 to 6. For the arrangement according to FIG. 3, however, it applies in particular that two further sensors are assigned to the sensor strips 12.
- the further sensors 13a and 13b are assigned to the sensor bar 12b.
- Further sensors 13a and 13c are assigned to the sensor bar 12c.
- Further sensors 13b and 13d are assigned to the sensor bar 12c.
- the sensor strips 12 are arranged together with the further sensors in a housing 18 which also has suitable lighting for the web 1, provided that no light source is integrated in the sensor strips.
- FIG. 4 shows an arrangement of the sensor strips 4a-4c as is already known from FIG. 1.
- the further sensors 5a - 5c are no longer upstream of the sensorists 4, but are connected downstream. This is measured by the direction of movement of the web 1 as indicated by the arrow 6.
- Lines 14a, 14b and 14c connect the sensor strips 4 and the further sensors 5 each to a processor 15a, 15b, 15c, which are connected to an input / output device 17 via lines 16a, 16b, 16c.
- An output 19 on the input / output device 17 serves, for example, as a connection to a computer, for example a so-called PC, to which several devices according to the invention can be connected.
- a further sensor 29 is here only assigned to the sensor bar 24 and detects a part of the web that is also detected by the sensor bar 24, the sensor bar 24 and the further sensor 29 not scanning the web according to the same criteria or not detecting the same features therein.
- FIG. 6 shows a further arrangement with five sensor strips 30, 31, 32, 33 and 34 and five further sensors 35, 36, 37, 38 and 39.
- the further sensors are each arranged next to those sensor strips for which they do not provide any movement information .
- the other sensors are seen in the direction of the movement of the web 1 alternately upstream and downstream of the assigned sensor strips.
- the further sensor 35 is connected downstream of the relevant sensor strip 30, while the further sensor 36 is connected upstream of the relevant sensor strip 31, or vice versa.
- FIG. 7 shows a path-time diagram, for example for the material web 1, a line 40 indicating the path of the material web 1 covered per unit of time with ideal, uniform movement of the material web 1 at all times.
- 42 values for the distance traveled and 41 values for the time can be plotted along an axis.
- a curve 43 represents the path actually covered by the web at different times, which is caused by the uneven movement of the web in the area of the sensor strips and other sensors.
- FIG. 8 shows a schematic representation of the conditions as they exist when an inclined sensor strip is arranged as shown in FIG. 2.
- 44 we designate a section through a group of weft threads of a fabric that moves in the direction of an arrow 45.
- the center lines or axes of these weft threads are drawn in with horizontal lines 46, the warp threads or their influence on these center lines or axes and thus the bindings being omitted here for the sake of simplicity.
- a sensor bar 47 is shown here only by those discrete elements that can capture image points from the web.
- the sensor bar 47 is here an optical sensor with a single image line.
- a coordinate system further identifies an X axis corresponding to the width of the web and a Y axis according to the direction of movement of the web 1.
- FIG. 9 shows a first signal 48 and a second signal 49 as a sensor strip can emit when it detects a tissue. Both signals 48, 49 are recorded over a time axis T, and next to an axis V, the axis V indicating the amplitude of the signal from the sensor strip, which is expressed, for example, by an electrical voltage.
- the operation of the invention is as follows:
- a sensor bar 4a (FIG. 4) scans the part 7a of the web 1 and maps it to pixels and converts it into intensity values, or into gray or color values that are stored in the processor 15a memory
- the further sensor 5a continuously inputs Signal to the processor 15a, which for example represents the momentary movement of the part 7a of the web 1 in the area of the sensor bar 4a.
- the further sensor 5a sweeps over a section within the part 7a of the web 1. This also applies to the further sensors 5b, 5c and the parts 7b, 7c of the web 1.
- the processors 15 contain a program in the program memory that contains periodicities or outstanding signal parts recognizes from the signal of the sensor bar and processes this together with the signal from the further sensor.
- the aim of this program is to form a clearly structured signal or a clear image from the signal of the sensor bar. This is to achieve, for example, that in an image that can be composed of the pixels in the data memory of a processor 15, the geometric relationships between the individual yarns or threads in a textile fabric are preserved in such a way that they correspond to those of the actual fabric. In the case of fabrics, the structure of the warp threads and the weft threads is to be made clearly recognizable. Original distances or geometrical relationships between warp and weft threads of a woven fabric or between threads of a knitted fabric are to be restored in the image.
- the further sensors 5, 10, 13, 29, 35 - 39 detect the movement of the material web 1, as is shown, for example, in FIG. 7. This shows that the web does not always cover the same distances per unit of time.
- the images captured by sensor strips 4, 9, 12 and 22-26 may not always contain the same number of elements as threads, weft threads, etc. If this image information is combined with the signal about the movement, for example from the further sensor, then a true image of the material web can also be created if its movement is uneven.
- the signal 48 results in particular by moving a point or a surface line 52 of the weft thread 50, which is also represented by the center line 51, past a sensor element 53, the sensor element 53 being able to generate an image point, which means that in this image point the intensity corresponds to the signal 48. If a short time later the weft thread 50 reaches a position (shown here for the sake of clarity) as it is designated by 54, which corresponds to a position of the center line corresponding to an interrupted line 55, then an adjacent sensor element detects 56 this weft thread in its position 54, whereby a signal 49 according to FIG. 9 arises which is delayed by a time ⁇ t to signal 48.
- the movement of the web 1 or a property related to the movement of the web can also be determined from the overlapping sensor strips, as shown for example in FIG. 3.
- the same parts of the web 1 are detected and thus comparable signals are generated, which, however, occur with a delay that corresponds to the Distance between the two sensor strips 12a and 12b divided by the speed of the web 1 corresponds in this area. Since the distance is known and the delay can be determined from both signals, the speed can be calculated therefrom.
- known sensors can be used, for example, under the designation “Contact Type Image Sensor”, such as are installed in a flatbed scanner or a fax machine for scanning a sheet of paper fed in.
- the sensors can directly touch the web, or they are covered by a cover plate made of glass, for example, which is touched by the material web.
- a small air gap can also separate the material web and the sensor.
- area cameras or To use line scan cameras which then scan a somewhat larger area of the web as seen in the direction of arrow 6.
- the further sensor 5, 10, 13 can be a sensor such as is known for example under the name “CMOS Active Pixel Image Sensor” and is offered by the company National Semiconductor. Another sensor such as that from the company Agilent Technologies under the Designation ADNS-2051 Optical Mouse Sensor offered can be used.
