Having. A measuring 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, in the transport direction indicated by the arrow in the drawing of the web 11. It has a thin aluminum-made receiving plate 23 extending in a direction perpendicular to the direction, 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.

The feed speed of the conveyors 5a and 5b is controlled so that the web 11 is drafted between the receiving plate 23 and the oblique feed conveyor 5b. The light emitter and the light receiver that constitute the web tension sensor 25a, which is a laser-type photoelectric sensor as a sensor for detecting the tension of the web 11 in the processing, are connected to the conveyer 5b of the web 11 at the transfer portion. They are installed to face each other so as to pass laser light in the directions. Accordingly, as shown in FIG. 9, when the web 11 which is normally moved with a certain degree of bending is stretched as shown by the imaginary line in the figure, the web stretching detection sensor 25a
, The laser beam is blocked, so that it is possible to detect that the web 11 is too tight.

FIG. 10 shows the chin roll 26 of the wrapper 6. Wrapper 6 on runout conveyor 5
Web 11 conveyed to the upper part of the floor conveyor 27
To be placed on the floor conveyor 27 via the chin roll 26. Chin roll 2
6 and the floor conveyor 27, the wrapper speed and the speed of the floor conveyor 27 are controlled so that the web 11 is drafted between the chin roll 26 and the floor conveyor 27 in the same manner as described above. In order to detect overstretching of the web 11 between
As shown in the figure, a light emitter and a light receiver constituting the web overstrength detection sensor 25b are installed so as to face each other corresponding to the position where the web 11 is overstretched. Also in this case, as shown in FIG. 11, the web 11 which is normally moved with a certain degree of flexure,
When the web 11 is stretched as indicated by the imaginary line in the figure, the laser beam is cut off by the web stretch detection sensor 25b, so that the web 11 can be detected as stretched.

As shown in FIG. 12, a windproof angle 29 is provided between the chin roll 26 and the upper roll 28 of the wrapper 6, and the width of the web 11 is continuously formed on the windproof angle 29. Web 11 to measure
As shown in FIG. 13, at the positions corresponding to both side edges of the web, a web width is formed by arranging seven reflective photoelectric sensors at an equal pitch p (for example, 10 mm pitch) in the width direction of the web 11. A measuring device 31 is provided. Therefore,
The width of the web 11 can be continuously measured at a pitch of 10 mm. Further, as shown in FIG. 14, an entanglement preventing plate 32 is provided at the tip of each photoelectric sensor, so that the passing web 11 can be prevented from being entangled with the tip of the photoelectric sensor. 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. Is sent in the direction of the arrow,
A bat cutter 34 for cutting the bat 33 into a predetermined width is provided. The butt cutter 34 is supported by a fixed beam (not shown), and is used to cut the bat 33 into a width set based on the initial data.
A pair is provided in the width direction 3 at predetermined intervals corresponding to the set values. The two butt cutters 34 are used to continuously cut off both ear portions of the bat 33 protruding outward from the set values with scissors 34a. Above the extension line of the 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.

As shown in FIG. 1, an operation panel 36 and a monitoring panel 37 each having a computer and a programmable controller as control means are installed near the second card machine 4 as shown in FIG. Each is electrically connected to control the operation of the device automatically. The monitoring panel 37 reads the detection signals from the sensors and the measuring devices described above. Operation panel 3
6, a device 38 for measuring and adjusting the breast rotation speed of each of the card machines 2 and 4 is incorporated. The breast rotation speed measurement and adjustment device 38 changes the breast rotation speed due to the slip of the belt of the drive motor due to the overload of the breast of each of the card machines 2 and 4 and the fluctuation of the supply voltage.
In order to prevent the occurrence of spots in the eye, 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 above-described sensors and measuring instruments will be described. Normally, each device and each machine are automatically operated based on the initial operation data. First, when the web raw material storage amount detection sensor 8 detects that the storage amount of the web raw material has become equal to or lower than a predetermined level, the transfer amount of the web raw material 9 may be reduced, which may cause spotting. 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 blanked on the base cloth in the needle machine 7, only the web production line can be stopped and the operation of the needle machine 7 can be continued.

When the halfway cut of the web 11 is detected by each of the halfway sensors 14a to 14c, the result of the abnormality detection is similarly output to the operation panel 36, and the operation is immediately interrupted. 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. .

When the swing width of the web 11 in the intermediate hair feeder 3 changes due to fluctuations in temperature and humidity in the factory,
When the web swing width detection sensor 15 detects that the swing width of the web 11 has deviated from the allowable value described above, the abnormality detection result is output to the operation panel 36 to cause periodic unevenness. , Stop driving. This can suitably prevent the production of the web 11 having large periodic unevenness. In addition, when a 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 spot due to the poor ear suction is detected at an early stage. I can deal with it.

Further, the web 1 is measured by the web width measuring device 31.
By measuring the width of 1, it is possible to detect a change in the web width due to a change within a permissible value such as a difference in the type of the web material 9, a change in suction at the ear sucking portion, and a change in the draft rate. This change in web width is caused by the butt 3 formed by overlapping the web 11 on the wrapper 6.
In the case of No. 3, the change in the weight per unit area has an influence, and therefore, it is necessary to adjust the weight per unit area in the subsequent process, or it causes 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 fed. The optimum value of the feeding speed for the target can be recalculated as appropriate, and the quality can be stabilized by improving the accuracy of the basis weight and reducing the V-shaped spots.

In the conventional manual operation, the weight per predetermined unit length is measured and used as a guide for the basis weight. However, in this case, since the basis weight is unknown, it is difficult to make the quality uniform. Was. By continuously measuring the weight of the web 11 by the web weight measuring device 22 as described above, the basis weight can be measured continuously, 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.
