The detection sensor 15 is for constantly monitoring whether or not both side edges, which are the folds of the web 11 conveyed in the direction indicated by the arrow in FIG. 4, are within a predetermined swing width. That is, a transmission type photoelectric sensor that forms a pair at predetermined intervals in the swing width direction corresponding to both side edges of the web 11.
15a and 15b are provided respectively. Double photoelectric sensor 15
When the edge measurement of the web 11 deviates from the allowable value (a in FIG. 5) defined by the interval between the a and 15b, it is possible to detect that the swing width is abnormal.

FIG. 6 shows a web manufactured by the second card machine 4.
An ear sucking device 18 is shown for sucking and separating the two ear portions, which are both side edges of the web 11, when the web 11 is peeled off from the doffer 4a. This ear sucking device 18 is
A pair of nozzles 19 provided at positions corresponding to the both ears 4 of the web 11 to be peeled off, a suction fan 20 connected to the nozzles 19 via a suction pipe, and a suction fan
And 20 negative pressure sensors 21 provided in the vicinity of the suction port. For example, when the entanglement of the fiber occurs at the edge of the web 11 due to the type of the web raw material and the like, and the nozzle 19 is clogged, the pressure change in the suction port is detected by the negative pressure sensor 21 and the set tolerance is set. An abnormality can be detected by comparing the value.

As shown in FIG. 7, the run-out conveyor 5 for conveying the web 11 manufactured by the second card machine 4 to the wrapper 6 includes a horizontal feed conveyor 5a continuous from the doffer 4a and the web 11 of the wrapper 6. And an oblique feed conveyer 5b for conveying toward the upper part. A weighing device 22 for measuring the weight of the web 11 when moving from one conveyor 5a to the other conveyor 5b is provided between the two conveyors 5a and 5b. As shown in FIG. 8, the weighing device 22 measures the weight of the web 11 while supporting the lower surface of the web 11 at the transfer portion between the conveyors 5a and 5b.
1 has a thin aluminum-made receiving plate 23 extending in a direction perpendicular to the transport direction indicated by the arrow in FIG. 1 and a pair of high-precision electronic weighing devices 24 that support both ends of the receiving plate 23. Therefore, the weight of the web 11 passing over the receiving plate 23 can be continuously measured with high precision, and the basis weight of the web 11 can be continuously measured.

In addition, both conveyors 5 are drafted so that the web 11 is drafted between the receiving plate 23 and the oblique feed conveyor 5b.
The feed speeds of a and 5b are controlled, and a light emitter and a light receiver constituting a web overstretching detection sensor 25a composed of a laser photoelectric sensor as a sensor for detecting the tension of the web 11 in the drafting process. The containers are arranged opposite to each other at the transfer portion of the web 11 to the conveyor 5b so as to pass the laser beam in the width direction of the web 11. Therefore, as shown in FIG. 9, when the web 11 which is normally moved with a certain degree of flexure when it is stretched as shown by the imaginary line in the drawing, the web tension detection sensor 25a Since the laser beam is cut off, it is possible to detect that the web 11 is too tight.

FIG. 10 shows the chin roll 26 of the wrapper 6. The web 11 conveyed to the upper part of the wrapper 6 on the runout conveyor 5 descends toward the floor conveyor 27,
It can be placed on a floor conveyor 27 via a chin roll 26. Chin roll 26 and floor conveyor 27
Between the two so that the web 11 is drafted,
The wrapper speed and the speed of the floor conveyor 27 are controlled, and in the same manner as described above, in order to detect excessive tension of the web 11 between the chin roll 26 and the floor conveyor 27, as shown in FIG. As shown in the figure, a light projector and a light receiver constituting the web overstretching detection sensor 25b are installed so as to face each other in correspondence with the web 11 overstretched position. In this case, too, as shown in FIG. 11, when the web 11 which is normally moved with a certain degree of flexure and is stretched as shown by the imaginary line in the figure, the web is detected as being excessively stretched. Since the laser beam is blocked by the sensor 25b, it is possible to detect that the web 11 is too tight.

As shown in FIG. 12, the chin roll 26 of the wrapper 6
A windproof angle 29 is provided between the upper roll 28 and the upper roll 28.The windproof angle 29 is provided at a position corresponding to both side edges of the web 11 in order to continuously measure the width of the web 11, As shown in FIG. 13, a web width measuring device 31 is provided in which seven reflection-type photoelectric sensors are arranged at an equal pitch p (for example, 10 mm pitch) in the width direction of the web 11. . Therefore, the width of the web 11 can be continuously measured at a pitch of 10 mm. In addition, as shown in FIG. 14, an entanglement preventing plate 32 is provided at the tip of each photoelectric sensor, thereby preventing the passing web 11 from being entangled with the tip of the photoelectric sensor. Note that the above-mentioned halfway cut detection sensor 14c is provided inside the web width measuring device 31.

As shown in FIG. 15, between the wrapper 6 and the needle machine 7, a sheet-like bat 33 made of a web folded in a plurality of layers by the wrapper 6 is directed toward the needle machine 7 in the figure. Bat 33
Is provided with a bat cutter 34 for cutting into a predetermined width. The bat cutter 34 is supported by a fixed beam (not shown), and a predetermined interval corresponding to the set value is provided in the width direction of the bat 33 in order to trim the bat 33 to the width set based on the initial data. And a pair is provided. With the two butt cutters 34, both ear portions of the bat 33 protruding outward with respect to the set value are continuously cut off by scissors 34a. Above the extension line of each scissors 34a along the feed direction of the bat 33, there is provided a resection failure detection sensor 35 composed of a reflective photoelectric sensor integrally attached to a support of the bat cutter 34 via a bracket. ing. Therefore, when the butt 33 is not completely cut, the defective cutting can be detected by the defective cutting detection sensor 35.

Further, an operation panel 36 and a monitoring panel 37 each having a computer and a programmable controller described later as control means are installed near the second card machine 4 as shown in FIG. Each is electrically connected for automatic operation control. The monitoring panel 37 reads the detection signals from the sensors and the measurement clothes. The operation panel 36 has a built-in measurement adjustment device 38 for the number of rotations of the breast of each of the card machines 2 and 4. The breast rotation speed measuring and adjusting device 38 causes a change in the breast rotation speed due to a change in the belt of the driving motor and a change in the supply voltage due to the breast overload of each of the card machines 2 and 4, and the web 11 has uneven spots. In order to prevent this, an allowable range of the breast rotation speed is set, and when a rotation speed abnormality is detected, an abnormality signal can be output to the operation panel 36. Further, a needle machine measurement control device 39 is installed near the needle machine 7, and performs operation control based on detection results of sensors described later in the needle machine 7.

Next, an embodiment of the control based on the detection results by the sensors and measuring devices described above will be described. Normally, each device and each machine are automatically operated based on the initial operation data. First, when the stored amount of the web raw material is detected by the web raw material storage amount detection sensor 8 to be equal to or lower than a predetermined level, the transport amount of the web raw material 9 may be reduced, and there is a possibility that a spotted spot may occur. Then, the result of the abnormality detection is output to the operation panel 36, and control for interrupting the operation by the operation panel 36 is performed. In the case where the bat 33 is idling the base cloth in the needle machine 7, the operation of the needle machine 7 can be continued by stopping only the web production line.

Also, when the halfway cut of the web 11 is detected by each of the halfway break sensors 14a to 14c, the abnormality detection result is similarly displayed on the operation panel.
Output to 36 to stop operation immediately. Therefore, since it is possible to quickly perform the detection by the visual confirmation by the operator as in the related art, the operation loss in the web production can be reduced, and the operation efficiency in the needle felt production process can be improved. .

If the swing width of the web 11 in the intermediate hair feeder 3 changes due to fluctuations in the temperature and humidity in the factory, it may cause periodic unevenness. When it is detected that the swing width has deviated from 11, the abnormality detection result is output to the operation panel 36, and the operation is interrupted. This results in a web with large periodic spots
11 can be suitably prevented from being manufactured. Also, when the suction abnormality is detected by the negative pressure sensor 21, the abnormality detection result is output to the operation panel 36 in the same manner, the operation is interrupted, and the cause of the web irregularity due to the above-mentioned poor ear suction is detected at an early stage. I can deal with it.

Further, by measuring the width of the web 11 by the web width measuring device 31, the web width due to a change within a permissible value such as a difference in the type of the web raw material 9, a change in suction at the ear sucking portion, and a change in the draft ratio is determined. Changes can be detected. This change in web width is caused by the web 11 in wrapper 6
Since the bat 33 formed by overlapping is influenced as a change in the weight per unit area, it is necessary to adjust the weight per unit area in a later process, and this may cause V-shaped spots. Therefore, by constantly feeding back the measured value of the web width, the wrapper speed, which is the feed speed of the chin roll 26 and the opposing roller 30 facing the chin roll 26 when the bat 33 is formed, and the needle machine 7 of the floor conveyor 27 are provided. The optimum value of the feed speed can be recalculated appropriately, and the quality can be stabilized by improving the accuracy of the basis weight and reducing the V-shaped spots.

Further, in the conventional manual operation, the weight per predetermined unit length was measured and used as a guide for the weight per unit area. However, in this case, since the weight per unit area was unknown, it was difficult to make the quality uniform. By continuously measuring the weight of the web 11 by the web weight measuring device 22 as described above, the basis weight can be continuously measured, and the quality can be stabilized and the precision of the basis weight measured value can be improved. Note that the measurement of the basis weight is not limited to the above-described structure, but may be another structure.
