  Next, as shown in FIGS. 9 and 10, the central control unit 201 drives the motors 154A and 154B via the motor controllers 206 and 207, and moves the magnetic sensors 164A and 164B of the measurement units 120A and 120B to the measurement reference position. (SA12, SA13). This measurement reference position is a position where the steel wire member 301 does not exist below the magnetic sensors 164A and 164B. In this embodiment, the position where the magnetic member 161 is fixed to the base 160 is the reference position Pn1, Pn2 (P12A, The position coincides with P12B).

  Thereafter, as shown in FIG. 11, the central control unit 201 drives the motor 154A via the motor controller 206 and moves the magnetic sensor 164A of the measurement unit 120A (SA14), and then outputs from the magnetic sensor 164A. It is determined whether or not the outer end of the steel wire member 301 has been detected based on the change in Hall voltage (SA15). When the steel wire member 301 is detected, the movement of the magnetic sensor 164A is stopped (SA16).

  Next, as shown in FIG. 12, the central control unit 201 drives the motor 154B via the motor controller 207 and moves the magnetic sensor 164B of the measurement unit 120B (SA17), and the hall output from the magnetic sensor 164B. It is determined whether or not the outer end of the steel wire member 301 has been detected based on a change in voltage (SA18). When the steel wire member 301 is detected, the movement of the magnetic sensor 164B is stopped (SA19).

  Next, based on the pulse count value input from the pulse generator 153A, the central control unit 201 moves the magnetic member 161 from the movement distance of the magnetic sensor 164A of the measurement unit 120A, that is, from the measurement reference position Pn1 (P12A (P21A)). The distance L6A to the position P22A fixed to the pedestal 160 is acquired (SA20), and the moving distance of the magnetic sensor 164B of the measuring unit 120B, that is, the measurement reference position based on the pulse count value input from the pulse generator 153B A distance L6B from Pn2 (P12B (P21B)) to a position P22B where the magnetic member 161 is fixed to the base 160 is acquired (SA21).

  Further, the central control unit 201 uses the following formulas (1), (2), and (3) to attach the ear rubber adhesion amount L7A on the measurement unit 120A side, the ear rubber adhesion amount L7B on the measurement unit 120B side, and the steel coating member 300. The width L10 is calculated (SA22, SA23, SA24), and the calculated ear rubber adhesion amounts L7A, L7B and the width L10 of the steel coating material 300 are displayed on the display unit 204 (SA25). The ear rubber adhesion amount L7A on the measurement unit 120A side is the distance between the side end position P13A of the steel coating material 300 and the position P14A of the outer end of the steel wire member 301 located on the outermost side. The side ear rubber adhesion amount L7B is a distance between the side end position P13B of the steel coating material 300 and the position P14B of the outer end of the steel wire member 301 located on the outermost side.

L7A = L4 + L6A-L5A (1)
L7B = L4 + L6B-L5B (2)
L10 = L1− (L2 × 2 + L5A + L5B) (3)
According to the above-described ear rubber adhesion amount measuring apparatus 1 of the present embodiment, the optical sensors A and B, that is, the measurement units 120A and 120B and the laser light emission units 131A and 131B are stopped at the time of measurement.

  Furthermore, in the present embodiment, the magnetic sensor 164A, 164B composed of a Hall element provided so as to be movable in the measurement units 120A, 120B detects the position of the steel wire member 301 present on the outermost side. As a result, the detection area can be narrowed, detection can be performed with higher accuracy, and vibrations caused by the movement of the magnetic sensors 164A and 164B can be suppressed. Can be reduced.

  Further, in this embodiment, after the optical sensors A and B (measurement units 120A and 120B and laser light emission units 131A and 131B) are stopped, the magnetic sensors 164A and 164B are directed outward in the width direction of the steel coating material 300. Since the steel wire member 301 is detected after moving and moving the magnetic sensors 164A and 164B to a position where the steel wire member 301 does not exist, the position of the outer end of the steel wire member 301 located on the outermost side is surely determined. Can be detected.

  Furthermore, the measurement units 120A and 120B and the laser light emission units 131A and 131B are moved at a position where the sum of the light reception amounts of the two light receivers 132A and 132B is about ½ of the total light reception amount stored at the time of initial setting. Since the steel coating material 300 is stopped, the steel coating material 300 can be moved without moving the measurement units 120A and 120B and the laser light emission units 131A and 131B even when the steel coating material 300 is displaced in the width direction or changes in width. The side end positions P13A and P13B can be acquired.

  Further, in this embodiment, since an advanced apparatus and processing such as X-ray image processing is not required, it can be realized at low cost.

  In addition, it is possible to always detect the presence of the steel wire member 301 in an optimum state by appropriately changing the energization current to the coil 162.

  Further, an alarm may be issued when the measured adhesion amount L7A, L7B of the ear rubber or the width L10 of the steel coating material 300 is outside a predetermined allowable range.

  Next, a second embodiment of the present invention will be described.

  In the second embodiment, the ear rubber adhesion amount of the steel coating material 300 conveyed at a predetermined speed by the conveying means 400 such as a conveyor is continuously and sequentially measured. In this way, when the ear rubber adhesion amount is continuously measured, as shown in the flowchart of FIG. 14, after the SA25 process is performed, the process proceeds to the SA10 process. Note that the processing of each step in the flowchart of FIG. 14 is the same as that of the first embodiment described above, and thus the description thereof is omitted.

  Also in this embodiment, the same effect as the first embodiment described above can be obtained. In this embodiment, since the steel coating material 300 that is the object to be measured is moving, the sum of the received light amounts of the two light receivers 132A and 132B is about ½ of the total received light amount stored at the time of initial setting. Since measurement is performed after the movement of the measurement units 120A, 120B and the laser light emission units 131A, 131B is stopped at the position, displacement in the width direction and fluctuation of the width occur as the steel coating material 300 moves. Even in this case, the side end positions P13A and P13B of the steel coating material 300 can be obtained without moving the measurement units 120A and 120B and the laser light emission units 131A and 131B.

  Next, a third embodiment of the present invention will be described.

  15 is a front view showing an ear rubber adhesion amount measuring apparatus according to the third embodiment of the present invention, FIG. 16 is a block diagram showing an electric circuit of the ear rubber adhesion amount measuring apparatus according to the third embodiment of the present invention, and FIG. These are flowcharts explaining operation | movement of the ear rubber adhesion amount measuring apparatus in 3rd Embodiment of this invention. In these drawings, the same components as those of the first embodiment described above are denoted by the same reference numerals, and the description thereof is omitted.

  In other words, the ear rubber adhesion amount measuring device 2 of the third embodiment includes a measuring mechanism unit 500 including a set of measuring units 120A and a laser light emitting unit 131A, and a computer device 200. The measurement mechanism unit 500 in the third embodiment is obtained by removing the left measurement unit 120B and the laser light emission unit 131A from the measurement mechanism unit 100 in the first embodiment. In addition, the control means related to the measurement unit 120B is removed.

  Therefore, the ear rubber adhesion amount measuring apparatus 2 of the present embodiment can only measure the ear rubber adhesion amount on one side in the width direction of the steel coating material 300 as the object to be measured, and can measure the width of the steel coating material 300. I can't.

  In the present embodiment, when the apparatus 2 is driven, laser light is emitted from the laser light emission unit 131A, and initial setting is performed by the central control unit 201 of the computer apparatus 200 as shown in the flowchart of FIG. SB1).

  In this initial setting, the central control unit 201 drives the motor 114 via the motor controller 205 and moves the measurement unit 120A and the laser light emission unit 131A to the right end of the ball screw 103, as shown in FIG. The position Pn1 (reference position of the measurement unit 120A) of the outer end of the laser beam received by the light receiver 132A of the measurement unit 120A is arranged to coincide with the initial position P11 of the end of the ball screw 103. Further, the central control unit 201 drives the motor 154A of the measurement unit 120A via the motor controller 206, and moves to a position where the magnetic member 161 of the measurement unit 120A does not block the laser beam. This position is set in advance in the program of the central control unit 201 as a distance (number of rotations of the motor 154A) from the position when the pedestal 160 is moved to the end of the ball screw 143. Furthermore, the central control unit 201 acquires data from the light receiver 132A and stores the amount of laser light received by the light receiver 132A as the total amount of light received.

  Next, the central control unit 201 drives the motor 114 via the motor controller 205 to move the measurement unit 120A and the laser light emission unit 131A toward the central part of the ball screw 103 (SB2) and input from the pulse generator 113. The reference position Pn1 of the measurement unit 120A is acquired by counting the number of pulses of the pulse signal to be performed (SB3). Further, the central control unit 201 acquires data of the amount of light received by the light receiver 132A (SB4).

  Next, the central control unit 201 determines whether or not the received light amount of the light receiver 132A is about ½ of the total received light amount stored at the time of initial setting. In the present embodiment, when the amount of light received by the light receiver 132A is within a range of 45% to 55% of the total amount of received light stored at the time of initial setting, it is determined to be about ½.

  As a result of the determination, when the received light amount of the light receiver 132A is not about ½ of the total received light amount stored at the time of initial setting, the process proceeds to the process of SB3. The drive of the motor 114 is stopped via the motor controller 205, and the movement of the measurement unit 120A and the laser beam emission unit 131A is stopped (SB6). At this time, the positions of the measurement unit 120A and the laser light emission unit 131A are as shown in FIG.

  Thereafter, the central control unit 201 determines the movement distance L2 of the optical sensor A, that is, the distance L2 between the initial position P11 and the reference position Pn1 (P12A) based on the pulse count value input from the pulse generator 113. At the same time (SB7), the incident light width L5A of the light receiver 132A is acquired (SB8). The incident light width L5A can be obtained by multiplying the ratio of the received light amount at the present time with respect to the received light amount in the initial state in the light receiver 132A by the width L3 of the laser light emitted from the laser light emitting unit 131A. it can. Thereby, the right end position P13A of the steel coating material 300 can be acquired.

  Next, as shown in FIG. 9, the central control unit 201 drives the motor 154A via the motor controller 206 and moves the magnetic sensor 164A of the measurement unit 120A to the measurement reference position (SB9). This measurement reference position is a position where the steel wire member 301 does not exist below the magnetic sensor 164A. In this embodiment, the position where the magnetic member 161 is fixed to the base 160 coincides with the reference position Pn1 (P12A). It is said.

  Thereafter, as shown in FIG. 11, the central control unit 201 drives the motor 154A via the motor controller 206 and moves the magnetic sensor 164A of the measurement unit 120A (SB10), and then outputs from the magnetic sensor 164A. It is determined whether or not the outer end of the steel wire member 301 has been detected by the change in Hall voltage (SB11), and when the steel wire member 301 is detected, the movement of the magnetic sensor 164A is stopped (SB12).

  Next, based on the pulse count value input from the pulse generator 153A, the central control unit 201 moves the magnetic member 161 from the movement distance of the magnetic sensor 164A of the measurement unit 120A, that is, from the measurement reference position Pn1 (P12A (P21A)). The distance L6A to the position P22A fixed to the pedestal 160 is acquired (SB13).

  Further, the central control unit 201 calculates the ear rubber adhesion amount L7A on the measurement unit 120A side according to the equation (1) (SB14), and displays the calculated ear rubber adhesion amount L7A on the display unit 204 (SB15). Note that the ear rubber adhesion amount L7A on the measurement unit 120A side is the distance between the side end position P13A of the steel coating material 300 and the position P14A of the outer end of the steel wire member 301 located on the outermost side.

  According to the above-described ear rubber adhesion amount measuring apparatus 2 of the present embodiment, the optical sensor A, that is, the measurement unit 120A and the laser light emission unit 131A are stopped at the time of measurement. Measurement error due to vibration can be reduced.

  Furthermore, in this embodiment, the magnetic sensor 164A made of a Hall element that is provided so as to be movable in the measurement unit 120A detects the presence position of the steel wire member 301 that is present on the outermost side. The area can be narrowed, detection can be performed with higher accuracy, and vibrations generated with the movement of the magnetic sensor 164A can be suppressed, and measurement errors due to the vibrations can be further reduced.

  In the present embodiment, after stopping the measurement unit 120A and the laser light emission unit 131A, the magnetic sensor 164A is moved toward the outside in the width direction of the steel coating material 300, and the magnetic sensor is moved to a position where the steel wire member 301 does not exist. Since the steel wire member 301 is detected after the 164A is moved, the position of the outer end of the steel wire member 301 located on the outermost side can be reliably detected.

  Furthermore, since the movement of the measurement unit 120A and the laser light emission unit 131A is stopped at a position where the light reception amount of the light receiver 132A is about ½ of the total light reception amount stored at the time of initial setting, the steel coating material 300 Even when a deviation in the width direction or a variation in the width occurs, the right end position P13A of the steel coating material 300 can be acquired without moving the measurement unit 120A and the laser light emission unit 131A.

  In addition, it is possible to always detect the presence of the steel wire member 301 in an optimum state by appropriately changing the energization current to the coil 162.

  Further, an alarm may be issued when the measured ear rubber adhesion amount L7A is outside a predetermined allowable range.

  Next, a fourth embodiment of the present invention will be described.

  In the fourth embodiment, using the ear rubber adhesion amount measuring device 2 of the third embodiment, the ear rubber adhesion amounts of the steel coating material 300 being conveyed at a predetermined speed by the conveying means 400 such as a conveyor are successively and sequentially. It was made to measure. In this way, when the ear rubber adhesion amount is continuously measured, the process of SB15 may be performed after the process of SB15 as shown in the flowchart of FIG. Note that the processing of each step in the flowchart of FIG. 18 is the same as that of the third embodiment described above, and thus the description thereof is omitted.

  Also in this embodiment, the same effect as the third embodiment described above can be obtained. In the present embodiment, since the steel coating material 300 that is the object to be measured is moving, the measurement unit 120A and the light receiving amount of the light receiver 132A are at positions that are approximately ½ of the total received light amount stored at the time of initial setting. Since the measurement is performed after the movement of the laser beam emission unit 131A is stopped, the measurement unit 120A and the laser are also detected even when a deviation in the width direction or a variation in the width occurs as the steel coating material 300 moves. The right end position P13A of the steel coating material 300 can be acquired without moving the light emission unit 131A.
