Description

The present invention relates to an operation monitoring system for a sieving device capable of discriminating the operating state of the sieving device.

Conventionally, there is a plan shifter as described in Patent Document 1 as a sieving device that performs a sieving process on powder or granular materials. The plan shifter includes a sieve frame body, and the sieve frame body is swayably suspended by a plurality of rods and installed in the building.

Then, in the operation of the plan shifter, the eccentric shaft provided at the substantially central portion of the sieve frame body rotates, so that the sieve frame body rotates and swings in the horizontal direction, and the sieving process is performed. ing. Further, when the plan shifter is installed, the balance weight is adjusted so that the rotation diameter due to the rotational swing of the sieve frame is within an appropriate range.

Then, in order to confirm whether or not the rotation diameter of the sieve frame body is within the appropriate range, conventionally, as shown in FIG. 6A, a felt-tip pen, a pencil, or the like is formed on the lower corner of the sieve frame body 5. The rotating circle was recorded by attaching the writing instrument of No. 1 and setting the recording paper under it, and the diameter of the rotating circle was measured with a ruler or the like. Further, the recording result of the rotating circle is compared with the graph showing the appropriate size of the circle with respect to the rotating speed as shown in FIG. 6B, so that the rotating diameter of the sieve frame 5 is within the appropriate range. It used a very primitive method, such as checking if it fits.

However, in the confirmation method as described above, when the flow rate or the load of the powder or granular material changes during the operation of the plan shifter, the rotation diameter of the sieve frame is abnormally changed due to the abnormality of the components of the plan shifter. Even if it occurred, there was a problem that it could not be noticed immediately.

(Plan shifter operation monitoring method)
Subsequently, the operation monitoring method of the plan shifter 1 in the present embodiment will be described. In the present embodiment, as shown in the perspective view of FIG. 1A, the operation state detection unit 7 is installed in advance on the sieve frame body 5, and the sieve frame body 5 is set to 4 before the plan shifter 1 is operated. The sieve frame body 5 is installed substantially horizontally while being suspended by the rod 3 of the book.

When the sieve frame body 5 is installed substantially horizontally and starts operation, the operation state detection unit 7 transmits arithmetic processing data to the operation monitoring device 9, and the operation monitoring device 9 monitors the operation state of the plan shifter 1. ..

FIG. 3 shows an example of the display mode in the operation monitoring device 9. More specifically, three Lissajous figures are displayed on the monitor screen, and the displacement amount of the sieve frame body 5 at the XYZ coordinates shown in FIG. 1A is displayed. That is, in the leftmost XY Lissajous figure, the current state of the circular motion of the sieve frame body 5 is displayed by a thick solid line, and the displacement amount is displayed below the XY Lissajous figure [X. = -38.8 to 38.4 mm], [Y = -38.2 to 38.1 mm], and [Z = −0.47 to 0.47 mm]. The display of these Lissajous figures and the amount of displacement is configured to be updated and displayed in real time.

Further, in the XY Lissajous figure, the limit displacement amount shown by the broken line is displayed as shown, and further, in the diagonally lower right of the XY Lissajous figure, the rotation speed [N = 220 rpm]. [X = -43.0 to 43.0 mm] and [Y = -43.0 to 43.0 mm] are displayed as the limit displacement amount. Since the limit displacement amount changes according to the rotation speed of the sieve frame body 5, the current rotation speed is displayed in real time, and the limit displacement amount is also constantly updated and displayed.

Further, on the right side of the XY Lissajous diagram, there is a YY Lissajous diagram showing the displacement amount of the sieve frame body 5 at the YY coordinate, and an X showing the displacement amount of the sieve frame body 5 at the XY coordinate. A −Z Lissajous diagram is displayed, and the displacement amount in the vertical direction (Z axis) of the sieve frame body 5 can be grasped in real time. In the example shown in FIG. 3, it is indicated by a solid line in the Lissajous diagram that there is no large displacement in the Z-axis direction, and further below the Z-axis, the displacement in the X-axis direction and the Y-axis direction is an angle of 90 degrees. [Θxz = 90.0 °] and [θyz = 90.0 °] indicating that are displayed. The operating state of the sieve frame body 5 can be easily determined by such a display mode.

Further, as shown in FIG. 3, a display area for displaying the operating state of the plan shifter 1 is provided at the upper part of the display screen of the touch panel 91 of the operation monitoring device 9, and the operating state of the sieve frame body 5 is displayed. It is configured to display "stable operation in progress" indicating that the vehicle is within the proper range.

Further, the operation monitoring device 9 of the present embodiment is operated when the displacement amount of the sieve frame body 5 is compared with the limit displacement amount serving as a threshold and the detected displacement amount is determined to be out of the appropriate range. It is configured to change the status display from "stable operation" to "abnormal operation detection" to give a warning. At this time, a speaker may be provided in the operation monitoring device 9 to sound an alarm sound. With this configuration, it is possible to grasp the change in the operating state more quickly.

Subsequently, FIG. 4 shows a display mode in the operation monitoring device 9 that displays the posture state of the sieve frame body 5. That is, an image imitating the three-dimensional sieve frame body 5 is displayed on the left side of the monitor screen, and the tilt status of the sieve frame body 5 based on the measurement data of the operation state detection unit 7 can be updated and displayed in real time. Has been done.

In addition, as shown in FIG. 4, a display area for displaying an image imitating a three-dimensional vector diagram is provided on the right side of the monitor screen of the present embodiment, and is used as measurement data of the operation state detection unit 7. The tilt status with respect to the XYZ axes based on the three-dimensional vector diagram is updated and displayed in real time. Further, below the three-dimensional vector diagram, the inclination angle from the normal state can be displayed, and in the example shown in FIG. 4, [X: −1.0 °] and [Y: -1]. The current tilt angle of the sieve frame 5 is displayed as [0.0 °].

The monitor screen shown in FIG. 4 is also configured to display a state such as "stable operation" in the same manner as the display mode of FIG. 3, and the inclination angle of the sieve frame body 5 is an allowable threshold value. If it exceeds, it is configured to change to a status display such as "abnormal operation detection". At the same time, it is also possible to perform notification by an alarm sound.

Although the first embodiment of the present invention has been described above, the characteristic structure as described above makes it possible to grasp the operating state of the sieve frame body 5 in real time from the start to the end of the operation of the plan shifter 1. Since it is configured, it is possible to prevent major failures and accidents, and it is possible to adjust and replace machines and equipment at appropriate timings, which greatly reduces the maintenance cost of the plan shifter 1. It is also possible.

Further, in the above-mentioned conventional technique, a space for attaching the measuring instrument is required at the lower corner of the sieve frame body 5, and the operating state of the sieve frame body 5 cannot be confirmed except at the relevant portion. Then, no matter where the operation state detection unit 7 is attached to the sieve frame body 5, the operation state of the sieve frame body 5 can be detected, and the attachment location is not restricted.

Further, in the above-mentioned conventional technique, since the writing instrument is attached to the lower corner of the sieve frame body 5, if the sieve frame body 5 is tilted during operation, a situation occurs in which a rotating circle cannot be recorded on the recording paper. However, in the present invention, since the operating state of the sieve frame 5 is detected without using any writing instrument or the like, it is possible to monitor the operating state more reliably and accurately than in the conventional case.

[Second Embodiment]
Hereinafter, the second embodiment according to the present invention will be described with reference to the device block diagram of the operating state detection unit 7 shown in FIG. The description of the same configuration as that of the first embodiment described above will be omitted.

In the first embodiment described above, the battery 714 is arranged as the power source of the operation state detection unit 7, but since the secondary battery needs to be charged, it is replaced with another charged battery 714 at an appropriate timing. Alternatively, the operating state detection unit 7 cannot be continuously used unless an adapter or the like is connected to the battery 714 to charge the battery. Therefore, there is a problem that the plan shifter 1 cannot be operated when the battery 714 is replaced or charged.

Therefore, in the second embodiment, as shown in FIG. 5, the battery 714 is applied instead of the vibration power generator 751 and the capacitor 752. According to such a configuration, the vibration power generator 751 generates electric power by the rotational operation of the sieve frame body 5, and the generated electric power can be stored in the capacitor 752 via the power supply circuit 713. Then, the electric power stored in the capacitor 752 is supplied as a power source for the operation state detection unit 7 via the power supply circuit 713. Therefore, it is possible to prevent the operation of the plan shifter 1 from being restricted by the charging operation of the battery 714, and to constantly monitor the operating state of the plan shifter 1.
