Next, the main body of the inking device is rotated as it is around the vertical axis, and the position of the other end of the line light is compared with the above-described marking position. The deviation is visually recognized depending on whether or not the amount of deviation at this time is larger than a specified value.

The calculation unit 6 calculates the laser beam tilt a predetermined number of times, and calculates an average value of the predetermined number of calculation results.

  In the following, the accuracy check device for the sumi appearance device of this embodiment will be described in more detail. As shown in FIG. 1, two orthogonal shafts 13 and 14 are disposed on an inner fixed frame 12 having an open bottom surface. The shaft 13 is fixed to the inner fixed frame 12, and the shaft 14 is fixed to the inner side. The bearings 14a and 14b provided on the frame 12 are rotatably connected. Further, the shaft 14 is fixed to an outer fixing frame (not shown) provided outside the inner fixing frame 12.

  The gimbal support 11 can always be suspended in the vertical direction by this gimbal mechanism regardless of the flat ground on which the accuracy check device A of the ink discharger is installed.

  Two photodetecting means 1 are arranged on the gimbal support 11 with an appropriate distance in the vertical direction. The light detection means 1 is a line or area CCD image sensor (photodiode). Further, a control unit 2 for driving the light detection unit 1, an I / V conversion unit 3 for converting a detection signal from the light detection unit 1 into a voltage, and an A / D conversion for converting the voltage signal into a digital signal. Part 4.

  Here, the laser beam in the vertical direction irradiated from the inking unit B is incident on the two light detection means 1a and 1b, and the intensity distribution of the light is output as a Gaussian distribution as shown in FIG. Is done. In addition, a comparison unit is provided that compares the values of the converted detection signals at the previous time point to obtain a peak value, and the peak value is set as the center position of the laser beam. Further, a calculation unit that calculates the inclination of the laser beam from the obtained peak value and a display unit 7 that displays the calculation result in the calculation unit are provided. Further, the display unit 7 can display the accuracy within the allowable range (OK) or outside the allowable range (NG).

  That is, the light detection means 1a outputs the output peak value IAmax at the time TA from the start of measurement, and the light detection means 1b outputs the output peak value IBmax at the time TB from the start of measurement. If there is no positional deviation between the respective light detection means 1a and 1b, the difference δ = | TA−TB | at this time represents the inclination of the laser light. Determination of accuracy means that the value of δ is 0 or within a predetermined range.

  FIGS. 3A and 3B show a front view and a side view of the accuracy check apparatus A for the ink marking device. The light detection means 1a and 1b are arranged on the surface of the gimbal support 11 with an appropriate distance in the Z direction, the detection area of the light detection means 1 extends in the Y axis direction, and the vertical line light It can be used for accuracy confirmation. Further, the outer fixed frame 15 is provided with legs 15a so that the device can stand on its own.

  Furthermore, as shown in FIG. 4, the light detection means 1a and 1b can be arranged on the surface of the gimbal support 11 with an appropriate distance in the Y direction. In this case, the detection area of the light detection means 1 extends in the Z-axis direction and can be used for checking the accuracy of the line light in the horizontal direction.

  Further, as shown in FIG. 5, four light detection means can be arranged on the surface of the gimbal support 11. In this case, the two light detection means 1a and 1b are arranged on the surface of the gimbal support 11 with an appropriate distance in the Y direction, and the two light detection means 1c and 1d are set with an appropriate distance in the Z direction. Thus, by arranging on the surface of the gimbal support 11, both the vertical method and the accuracy of the line light in the horizontal direction can be confirmed by the accuracy checker A of one inking device.

  FIG. 6 is a perspective view showing a situation in actual use. An inking machine accuracy check device A is placed at a predetermined distance from the wall surface 100, and laser light is projected from the inking machine B for use. As shown in FIG. 7, the gimbal support 11 of the accuracy checker A for the marking device is provided with light receiving means 10R, 10C, and 10L. The target position to be aligned with the position PQ of the line light when the ink removal device B is initially installed and the laser beam is irradiated is defined as a position P′Q ′. In this case, the main body of the deinking device B is rotated to move the line light to the position P′Q ′. In order to determine whether or not the line light matches the position P′Q ′, the light receiving means C is aligned with the position P′Q ′ in advance, and the line light is received by the notification means using light or sound. By notifying the operator of the position of C, R, or L, the alignment of the line light becomes very easy. By adopting such a configuration, it is possible to have two types of functions of checking accuracy of laser light and positioning.

  Next, the calculation of the tilt of the laser beam by the calculation unit 6 of the accuracy check apparatus A for the ink marking device will be described with reference to FIGS. FIG. 8 shows the address and light intensity of the peak value of the laser beam detected by the light detection means 1a and 1b when calibration is performed. In this case, the amount of inclination δ can be obtained from the difference between the addresses na and nb of the peak values obtained by the light detection means 1a and the light detection means 1b. The inclination amount δ is stored as an initial value in a memory unit (not shown) in the calculation unit 6.

  FIG. 9 shows the address and light intensity of the peak value of the laser light detected by the light detection means 1a and 1b at the time of confirmation. If the amount of inclination in this case is δ ′, the amount of inclination δ ′ can be obtained by the difference between the peak value addresses na ′ and nb ′ obtained by the light detecting means 1 a and the light detecting means 1 b. If the absolute value of the difference between the tilt amount δ at the time of calibration and the tilt amount δ 'at the time of confirmation is greater than the specified value ε, the accuracy is outside the allowable range, and if it is small, the accuracy is determined to be within the allowable range. The

  The determination flow is shown in FIG. That is, the peak value is searched and detected by the comparison unit 5 based on the amount of incident light (step S1). Further, the address of the peak value is stored in a memory unit (not shown) in the calculation unit 6 (step S2), and the calculation unit 6 calculates the inclination amount δ 'at the time of confirmation (step S3). The absolute value of the difference between the inclination amount δ at the time of calibration and the inclination amount δ ′ at the time of confirmation stored in advance in a memory unit (not shown) is calculated and compared with the specified value ε (step S4). If the calculated absolute value is smaller than the specified value ε, it is determined that the accuracy is within the allowable range. If the calculated absolute value is greater than the specified value ε, the accuracy is determined to be outside the allowable range. Is done.

  Further, the amount of inclination δ at the time of calibration and the amount of inclination δ ′ at the time of confirmation are obtained by repeatedly calculating a predetermined number of times, and the average value thereof is calculated and used for judgment, thereby further improving the stability of accuracy confirmation. Can be improved.

  Therefore, since the plurality of light detection means 1 are provided on the gimbal support 11 suspended by the swingable gimbal mechanism, the plurality of light detection means 1 can be arranged with high accuracy. Furthermore, since the laser light emitted from the ink discharger B can be made incident on the plurality of light detection means 1, the inclination of the laser light can be calculated using a plurality of light detection results, and high accuracy can be obtained. I can confirm.

  Furthermore, since the light detection means 1 is disposed so as to have a light detection area in a direction perpendicular or parallel to the direction in which the gimbal support 11 is suspended, the light detection means 1 is irradiated from the inking device B. The accuracy of vertical line light or horizontal line light can be confirmed.

  Since the light receiving means 10 for detecting the laser light is provided separately from the light detecting means 1, the light receiving means 10 can function as a light receiver, and the operator can quickly bring the line light to a desired position. Can be matched.

  Further, the calculation unit 6 uses the position of the peak value obtained by the comparison unit 5a from the detection signal detected by the light detection unit 1a as a reference position, and obtains it by the comparison unit 5b from the detection signal detected by the light detection unit 1b. Since the inclination of the laser beam is calculated from the relationship between the position of the obtained peak value and the reference position, highly accurate inclination data can be obtained, and accurate measurement can be performed.

  Furthermore, since the laser beam tilt is calculated a predetermined number of times and the average value of the predetermined number of calculation results is calculated, a stable measurement value can be obtained.

  Next, a description will be given of an accuracy check device for a deinking device according to a second embodiment of the present invention. Here, only matters different from those in the first embodiment will be described, and other matters (configuration, operational effects, and the like) are the same as those in the first embodiment, and thus description thereof will be omitted.

  The control unit 2 operates the plurality of light detection units 1 in synchronization, and the calculation unit 6 is the time from the start of operation of the plurality of light detection units 1 to the acquisition of the peak value obtained by the comparison unit 5. And the inclination of the laser beam is calculated using the difference between the light detection means 1 in the time.

  FIG. 11 shows the relationship between the passage of time after the light detection means 1 is activated and the light intensity. The peak value is detected using the signals detected by the light detection means 1a and the light detection means 1b. The inclination amount δt can be calculated from the time difference tb−ta between the peak value time ta of the light detection means 1a and the peak value time tb of the light detection means 1b. The inclination amount δt is stored as an initial value in a memory unit (not shown) in the calculation unit 6.

  FIG. 12 shows the relationship between the passage of time and the light intensity after starting the light detection means 1 of the laser light detected by the light detection means 1a and 1b at the time of confirmation. If the amount of inclination in this case is δt ′, the amount of inclination δt ′ is inclined by the time difference tb′−ta ′ between the time ta ′ of the peak value of the light detection means 1a and the time tb ′ of the peak value of the light detection means 1b. The quantity δt ′ can be calculated. If the absolute value of the difference between the inclination amount δt at the time of calibration and the inclination amount δt ′ at the time of confirmation is larger than the specified value ε, the accuracy is outside the allowable range, and if it is small, the accuracy is determined to be within the allowable range. The

  This determination flow is shown in FIG. That is, the peak value is searched and detected by the comparison unit 5 based on the amount of incident light (step S1). Further, the passage of time since activation of the light detection means 1 is stored in a memory unit (not shown) in the calculation unit 6 (step S2), and the calculation unit 6 calculates a tilt amount δt ′ at the time of confirmation. (Step S3). The absolute value of the difference between the inclination amount δt at the time of calibration and the inclination amount δt 'at the time of confirmation stored in advance in a memory unit (not shown) is calculated and compared with the specified value ε (step S4). If the calculated absolute value is smaller than the specified value ε, it is determined that the accuracy is within the allowable range. If the calculated absolute value is greater than the specified value ε, the accuracy is determined to be outside the allowable range. Is done.

  Therefore, since the time until the acquisition of the peak value is measured and the inclination of the laser light is calculated using the difference between the light detection means 1 of the time, highly accurate inclination data can be obtained, Accurate measurement is possible.

  Next, a description will be given of an accuracy check device for a deinking device according to a third embodiment of the present invention. Here, only matters different from those in the first and second embodiments will be described, and other matters (configuration, operational effects, etc.) are the same as those in the first and second embodiments, and therefore the description thereof. Is omitted.

  As shown in FIG. 14, the accuracy checker A for the ink marking device has a structure in which the entire gimbal mechanism is covered with a box-shaped device housing 16, and the gimbal support 11 detects an excessive inclination of itself. Inclination detecting means 17 is provided.

  As shown to Fig.14 (a), the over-inclination detection means 17 is comprised by the contact support body 17a, the contact 17b, the power supply 17c, and the detection part 17d. The device housing 16 is provided with a contact 17 b at the tip of a contact support 17 a that protrudes toward the gimbal support 11. The gimbal support 11 is formed of a conductor, and the upper end of the gimbal support 11 and the contact point 17b are electrically connected to the power source 17c and the detection unit 17d.

  As shown in FIG. 14 (b), when the accuracy checker A for the ink marking device is installed on an inclined installation surface, the gimbal support 11 comes into contact with the inner surface of the device housing 16, and accuracy is checked. There is a risk of hindrance. Therefore, when the gimbal support 11 is inclined more than a certain level, the side surface of the gimbal support 11 comes into contact with the contact 17b, and a current flows through the gimbal support 11, the contact 17b, and the detection unit 17d by the power source 17c. Become. When the current is detected by the detection unit 17d, the detection result can be sent to the calculation unit 6, and the display unit 7 can be informed that the state is over-inclined to notify the operator.

  In the present embodiment, the over-tilt detection means 17 is configured to flow current using the gimbal support 11 as a conductor. However, the present invention is not limited to this, and a contact switch is provided in the contact 17b portion. The structure which detects that the side surface of the gimbal support body 11 contacts a press sensor and it is an excessive inclination may be implement | achieved by using the mechanical press sensor which performs.

  Therefore, since the gimbal support 11 has the over-inclination detecting means 17 for detecting that the gimbal support body 11 is over-inclined, it is abnormal if the operator mistakenly tilts the accuracy check device A of the inking device. It can be easily detected.

  Next, a description will be given of an accuracy check device for a deinking device according to a fourth embodiment of the present invention. Here, only matters different from those in the first to third embodiments will be described, and other matters (configuration, operational effects, etc.) are the same as those in the first to third embodiments, and thus the description thereof. Is omitted.

  The gimbal support 11 is configured to be swingable by a gimbal mechanism. However, when measuring, the gimbal support 11 needs to be swung faster. Therefore, as shown in FIG. 15, the accuracy checker A for the ink marking device has a magnetic body 18 disposed at a predetermined distance from the tip 11 a of the gimbal support 11. The tip part 11a of the gimbal support 11 is provided with a conductor having high conductivity (for example, copper), and the magnetic body 18 is installed at a position spaced apart by a predetermined distance. When the gimbal support 11 is swung, the eddy current generated when the conductor of the tip 11a crosses the magnetic field lines of the magnetic body 18 causes a magnetic field that attracts the tip 11a and the magnetic body 18 to each other. 18 is generated.

  Therefore, since the magnetic body 18 is disposed at a predetermined distance from the distal end portion 11a of the gimbal support 11, the gimbal support 11 can be quickly damped by the induced current generated by the magnetic body 18 when swinging, Accurate measurement is possible.

  Next, a description will be given of an accuracy check apparatus for a deinking device according to a fifth embodiment of the present invention. Here, only matters different from those in the first to fourth embodiments will be described, and other matters (configuration, operational effects, etc.) are the same as those in the first to fourth embodiments, and therefore the description thereof. Is omitted.

  As shown in FIG. 16, the inking device accuracy check apparatus A includes an attaching member 19 that can be integrally formed with the inking device B attached thereto.

  Therefore, since the attachment member 19 that can be integrally formed by attaching the inking device B is provided, the inking device B can be arranged at a certain distance from the accuracy checking device A of the inking device. Stable measurement is possible.

  Further, since the installation position of the inking device B with respect to the accuracy checking device A at the time of calibration and the setting position of the inking device B with respect to the accuracy checking device A at the time of checking are the same, the amount of inclination is calculated. Therefore, it is not necessary to consider the variation in the distance between the device B and the accuracy confirmation device A, and accurate accuracy confirmation can be performed.

  Furthermore, the accuracy checking device A of the marking device B can check the accuracy of the laser beam at a distance close to the marking device B. The example shown in FIG. 17 is a case where the center of the deinking device B is O and the apparatus is placed at a position P at a distance L, but the line in which PQ2 ′ has fallen with respect to the thread PQ2 that swings down the wall surface. If it is light, the amount of inclination δ can be calculated with the positions of the light detection means 1a and 1b as P and Q. Here, when the accuracy checking device A for the ink marking device is installed at the position P1, the triangular pyramid OP1Q1Q1 ′ and the triangular pyramid OPQ2Q2 ′ are similar and have a ratio of L1: L, so that L1: L = PQ: The relationship of PQ2 is established. Here, when PQ2 = 3000 mm, OP = 5000 mm, and PQ = 150 mm, L1 = 250 mm. As described above, since the accuracy check can be performed by installing the inking device accuracy checking device A and the inking device B at close distances, the accuracy can be easily checked even in a narrow space.
