Description

The present invention relates to a level indicator level adjuster that automatically positions the relative position of the level indicator relative to a support of a structure, and a program that can be applied to the level indicator level adjuster.

In the construction of structures, for example, in the construction of buildings using concrete, the foundation on which the upper surface (this is referred to as the "top" in this specification) is horizontal is laid on the ground by placing concrete. It will be installed on top and the foundation of the building will be laid on this foundation. At this time, in order to adjust the height of the top of the foundation, a slurry of mortar having self-hardening property (in this specification, this is applied on the skeleton of the foundation, which is composed of reinforced materials embedded in concrete. It has been conventionally practiced to pour a "leveler") and harden it, and use the upper surface of the hardened mortar as the top of the foundation.

Here, when the leveler is poured onto the skeleton of the foundation, a level indicator that serves as a reference for the upper end position of the leveler to be poured in order to position the top end formed by hardening the leveler at a predetermined vertical position. Is used. This level indicator is attached to a fixture that is supposed to be embedded in concrete in the skeleton of the foundation. Further, the level indicator is engaged with the fixture so as to be able to move up and down, and the position in the vertical direction can be adjusted. By setting the upper end of this level indicator as the reference position of the top edge of the foundation (this is referred to as "level" in the present specification), the upper end position of the leveler to be poured can be determined.

By the way, since the leveler absorbs water on the concrete and the fluidity is lowered, the range of the leveler that spreads on the concrete of the foundation skeleton is limited. For this reason, when leveling all the tops of the foundation in a relatively large building with a leveler, it is necessary to pour the leveler at multiple locations on the foundation frame, and level indicators are used at these multiple locations. It is necessary to adjust the level so that it is positioned at the same level. When this level adjustment is performed manually, there is a problem that an error is likely to occur in the level of each level indicator and the working time becomes long.

Therefore, a technique of an automatic level adjusting device that automatically adjusts the level of the level indicator has been proposed (see, for example, Patent Document 1). This automatic level adjusting device includes a device that irradiates a laser beam horizontally, a light receiving portion of the laser beam, and a motor connected to a driver. This motor is interlocked with the light receiving unit and raises and lowers the screw (that is, the level indicator) used for the reference point. When the light receiving unit senses the laser beam that becomes the benchmark when rising, it rises as it is, and after the motor stops, it shifts to the descending control, and when the light receiving unit detects the laser beam that becomes the benchmark again, it stops.

Utility Model Registration No. 3193735

Note that Patent Document 1 does not show a specific configuration of the automatic level adjusting device, and the details thereof are unknown. Further, as described above, it is necessary to adjust the level of the level indicator at a plurality of places. Here, in the technique described in Patent Document 1, when the automatic level adjusting device is to be detached from the level indicator after adjusting one level indicator, a portion other than the reference point in the light receiving portion is used. However, the driver of the automatic level adjusting device was driven by detecting the laser beam, and there was a possibility that the level of the level indicator which had finished adjusting the folding angle level would shift. To deal with this, it is possible to turn off the power of the automatic level adjuster once and then disconnect the automatic level adjuster from the level indicator. In this case, smooth level adjustment of multiple level indicators is achieved. Becomes difficult.

Therefore, the present invention solves the above-mentioned problems, and can automatically adjust the level of the level indicator, and at the same time, improve the accuracy of the level adjustment and smooth the separation from the level indicator. It is an object of the present invention to provide a level adjusting device for a level indicator that can be planned, and a program for operating the level adjusting device.

One of the features of the present invention, which is a means for that purpose, is a driver that engages with a level indicator attached to a support of a structure and moves the level indicator in one direction, and a marking light emitted from the outside. It has a sensing area that senses light, and three areas, a first area, a central area, and a second area, which are connected and lined up from one side to the other in one direction, are set in the sensing area, and When the driver moves the level indicator forward and backward in one direction, the optical sensor keeps the relative distance to the level indicator in one direction constant by moving forward and backward following the level indicator. It is a level adjusting device for a level indicator including a control unit that controls the driving of the driver according to the information from the optical sensor. The control unit controls to realize a plurality of functions including a determination function, a first movement function, a second movement function, an advance / retreat stop function, a movement continuation function, and a maintenance function, and displays a level on the support. Position the relative position of the tool as seen from one direction. The determination function determines whether or not the marking light hits the sensing area of the optical sensor, and if the marking area is hit by the marking light, the marking light hits the first area, the central area, and the first area. It determines which of the two areas it corresponds to. In the first movement function, the driver moves the level indicator to one side while it is determined by the determination function that the marking light hits the first area. In the second movement function, the driver moves the level indicator to the other side while the determination function determines that the marking light hits the second area. The advance / retreat stop function is activated when the marking light hits the central area after it is determined by the determination function that the marking light hits the first area, and stops the advance / retreat of the level indicator by the driver. The movement continuation function is activated when the marking light is determined to hit the second area by the determination function and then triggered by the marking light hitting the central area, while the marking light is determined to hit the central area. The driver continues to move the level indicator to one side. The maintenance function is triggered by the driver's advance / retreat of the level indicator being stopped by the advance / retreat stop function, and maintains the level indicator for a predetermined time in a state where the driver's advance / retreat of the level indicator is stopped.

According to this, when the marking light first hits the first area of the optical sensor, the place where the marking light hits on the optical sensor moves from the first area toward the central area (first movement). Function), then stop when entering the central area (advance / retreat stop function). On the other hand, when the marking light first hits the second area of the optical sensor, the place where the marking light hits on the optical sensor moves from the second area toward the central area (second movement function), and this It passes through the central area and reaches the first area (movement continuation function), then moves from the first area toward the central area (first movement function), and then stops when it enters the central area again (advance / retreat). Stop function). That is, regardless of whether the place on the optical sensor where the marking light hits is shifted to either one side or the other side when viewed from the central area of the optical sensor, the place where the marking light hits on the optical sensor is the first area. When switching from to the central area, the level indicator stops its advance and retreat. Therefore, even if the width is provided in the central area, the accuracy of the position where the level indicator is stopped can be improved.

In addition, after the level adjustment of the level indicator is completed, the level adjuster for the level indicator is used for a predetermined time regardless of how the marking light hits the optical sensor of the level adjuster for the level indicator. The advance / retreat of the level indicator stops. That is, when the level indicator level adjuster or the device that emits the marking light is removed after the level adjustment of the level indicator is completed, the marking light from this device is the light of the level indicator level adjusting device. It is possible to prevent the level indicator from moving back and forth by hitting the sensor and shifting the level of the level indicator. That is, the level adjusting device for the level indicator can be smoothly separated from the level indicator. Further, after the level adjustment is completed, it is possible to secure a time grace period for confirming whether the level adjusting device for the level indicator is in the desired direction for advancing and retreating the driver.

In one of the preferred forms of the level adjusting device for a level indicator having one of the above features, the maintenance function can be a function stop function. This function stop function is activated when the driver stops the advance / retreat of the level indicator by the advance / retreat stop function and then a predetermined time elapses, and the first movement function, the second movement function, and the advance / retreat stop are activated. The function and the movement continuation function are put into a non-functional state.

According to the above configuration, when the level adjusting device for the level indicator is separated from the level indicator after the level adjustment of the level indicator is completed, the first movement function, the second movement function, the advance / retreat stop function, and the advance / retreat stop function, and , The movement continuation function is not realized at all. Therefore, it is possible to more reliably prevent the level indicator, which has once completed the level adjustment, from advancing and retreating.

In one of the more preferable forms in the above preferred form, the control unit further controls to realize the function restoration function. The function restoration function is activated when the condition that the judgment function determines that the marking light hits the optical sensor continues for a certain period of time or longer is satisfied after the function stop function is activated. The functions of the first movement function, the second movement function, the advance / retreat stop function, and the movement continuation function, which are in the stopped function state, are restored.

According to the above configuration, the first movement function, the second movement function, the advance / retreat stop function, and the movement continuation function, which are in the stopped function state, are used until a certain time elapses after the light sensor is exposed to the marking light. Will not be resurrected. Therefore, when the level adjuster for the level indicator is separated from the level indicator and the level adjustment of another level indicator is to be started, the user engages the driver of the level indicator with the level indicator. Grace time is given. As a result, after adjusting the level of the level indicator, it becomes possible to engage with another level indicator more smoothly and adjust the level.

Another feature of the present invention is that it engages with a level indicator attached to a support of a structure and moves the level indicator in one direction, and senses the marking light emitted from the outside. The sensing area is divided into three areas, a first area, a central area, and a second area, which are connected and lined up from one side to the other in one direction, and the driver is leveled. When moving the display in one direction, it is equipped with an optical sensor that keeps the relative distance to the level display in one direction constant by moving back and forth following the level display. The level adjustment device for the level indicator that positions the relative position of the level indicator with respect to the body when viewed from one direction includes a judgment function, a first movement function, a second movement function, an advance / retreat stop function, and a movement continuation function. It is a program that realizes multiple functions including maintenance function. The determination function determines whether or not the marking light hits the sensing area of the optical sensor, and if the marking area is hit by the marking light, the marking light hits the first area, the central area, and the first area. It determines which of the two areas it corresponds to. In the first movement function, the level indicator is moved to the one side by the driver while it is determined by the determination function that the marking light hits the first area. In the second movement function, the driver moves the level indicator to the other side while the determination function determines that the marking light hits the second area. The advance / retreat stop function is activated when the marking light hits the central area after it is determined by the determination function that the marking light hits the first area, and stops the advance / retreat of the level indicator by the driver. The movement continuation function is activated when the marking light is determined to hit the second area by the determination function and then the marking light hits the central area, and the marking light hits the central area. While the determination is made, the driver continues to move the level indicator toward the one end side. The maintenance function is triggered by the driver's advance / retreat of the level indicator being stopped by the advance / retreat stop function, and maintains the level indicator for a predetermined time in a state where the driver's advance / retreat of the level indicator is stopped.

According to this, a level adjusting device for a level indicator provided with a driver and an optical sensor and positioning a relative position of the level indicator with respect to a support is provided for level adjustment for the level indicator according to one of the features of the present invention described above. It can function as a device.

Further, in one of the preferred embodiments in the above program, the maintenance function can be a function stop function. This function stop function is activated when the driver stops the advance / retreat of the level indicator by the advance / retreat stop function and then a predetermined time elapses, and the first movement function, the second movement function, and the advance / retreat stop are activated. The function and the movement continuation function are put into a non-functional state.

According to the above configuration, a level indicator level adjusting device including a driver and an optical sensor and positioning the relative position of the level indicator with respect to the support is one of the preferred forms of the level indicator level adjusting device described above. Can function as.

In one of the more preferred embodiments of the program of the preferred embodiment, the level adjusting device for the level indicator realizes the function restoration function. In the function restoration function, when the first movement function, the second movement function, the movement continuation function, and the advance / retreat stop function are stopped by the function stop function, the marking light is emitted by the judgment function. The first movement function, the second movement function, the movement continuation function, and the movement continuation function, which are in the stopped state, are triggered by the condition that the state in which the sensor is hit is determined to continue for a certain period of time or longer is satisfied. It restores each function of the advance / retreat stop function.

According to the above configuration, a level indicator level adjusting device including a driver and an optical sensor and positioning the relative position of the level indicator with respect to the support is one of the more preferable forms of the level indicator level adjusting device described above. It can function as a screwdriver.

According to the present invention, the level of the level indicator can be automatically adjusted, and at the same time, the level adjustment accuracy of the level indicator can be improved and the level indicator can be smoothly separated from the level indicator.

In the following, the upper direction is referred to as "upper side" and the lower direction is referred to as "lower side" when the level adjusting device 1 for level indicators is used at the foundation construction site (see FIG. 2).

As shown in FIG. 1, the level adjusting device 1 for a level indicator according to the embodiment includes a driver 10, a control unit 20, and an optical sensor 30. The driver 10 includes a cover 11 and a rotating shaft 12. The cover 11 is formed in a rectangular cylinder shape. Further, the rotating shaft 12 is formed in a long axis shape, and an engaging portion 12a formed in a bifurcated shape is formed at the tip thereof. The rotating shaft 12 is inserted into the rectangular tubular cover 11 and is rotatably fixed.

The control unit 20 is provided with a power button 21, an auto button (auto manual switching button) 22, an ascending button 23, and a descending button 24, as well as a power LED 25, an auto mode LED 26, and an adjustment completion LED 27. Of these buttons, at least the ascending button 23 and the descending button 24 are double action switches. In the present specification, the "double action switch" refers to a push button switch that produces different operation results depending on whether a half-press that is lightly pressed on the switch or a full-press that is strongly pressed on the switch. That is, it refers to a switch that can detect and distinguish between a simple press (half press) and a long press (full press). Further, the control unit 20 has a built-in sound source (not shown). This sound source is configured to emit three types of beep sounds (beep sound A, beep sound B, and beep sound C) in response to a control signal from the control unit 20.

Further, a connection terminal 20a is provided at the lower end of the control unit 20, and a wired connection with the optical sensor 30 described later is performed. Further, the control unit 20 has a built-in motor (not shown). Further, the control unit 20 has a recording medium (not shown), and a program described later is recorded on the recording medium. In this recording mode, a circuit arranged in the control unit 20 is used as a recording medium, and a wired logic mode for recording a program by connecting the circuits, or a storage arranged in the control unit 20 is used as a recording medium, and this storage is used. The program may be recorded in a computer-readable manner. The motor of the control unit 20 is driven according to the instruction of the above program. The motor is connected to the rotating shaft 12 of the driver 10, and the rotating shaft 12 also rotates in accordance with the rotation of the motor.

The optical sensor 30 includes a sensor unit 31 and a handle unit 32. The sensor portion 31 has a vertically long rectangular shape, and a rectangular frame portion 31a is provided along the vertical direction. A sensing area 40 for sensing the hit light is formed on the bottom of the frame portion 31a.

As shown in FIG. 3, the sensing area 40 has a configuration in which two elements, an upper sensing unit 40a and a lower sensing unit 40b, are arranged one above the other in this order. The upper sensing unit 40a and the lower sensing unit 40b each output an output of a current amount corresponding to the amount of light struck, and emit a signal converted from this output. Based on these signals, the optical sensor 30 determines whether or not the marking light from the outside (specifically, the marking light R emitted by the laser oscillator 3 shown in FIG. 2) hits the sensing area 40, and the marking. When the emitted light hits the sensing area 40, it senses which of the first area 41, the second area 42, and the central area 43, which is the area virtually set in the sensing area 40, is hit by the marking light. Here, the first area 41 is set as an area in which the amount of light that hits the upper sensing unit 40a is significantly larger than the amount of light that hits the lower sensing unit 40b. Further, the second area 42 is set as an area in which the amount of light that hits the upper sensing unit 40a is significantly smaller than the amount of light that hits the lower sensing unit 40b. Further, the central area 43 is set as an area where there is no significant difference between the amount of light hitting the upper sensing unit 40a and the amount of light hitting the lower sensing unit 40b. Therefore, the central area 43 has a certain gap d (see FIG. 3) sandwiched between the virtual boundary line 43a located on the upper sensing unit 40a and the virtual boundary line 43b located on the lower sensing unit 40b (see FIG. 3). ) Is the area. Further, in the sensing area 40, the first area 41 is an area above the central area 43, and the second area 42 is an area below the central area 43 as the second area 42. The "upper side" corresponds to the "one side" in the present invention, and the "lower side" corresponds to the "other side" in the present invention.

Further, a connection terminal 31b is provided at the upper end of the optical sensor 30. The connection terminal 31b is connected to the connection terminal 20a (see FIG. 1) of the control unit 20 described above, the control unit 20 and the optical sensor 30 are connected by wire, and the information from the optical sensor 30 is transmitted to the control unit 20.

As shown in FIG. 1, the handle portion 32 fixes the sensor portion 31 to the driver. The handle portion 32 includes a handle portion main body 32a, a holding portion 32b, and a fastener 32c. The handle portion 32 is a substantially L-shaped member composed of a back portion and a bottom portion to which the optical sensor main body 31 is attached. A groove is provided in the back portion of the handle portion main body 32a, and the sandwiching portion 32b is fitted into the groove so that the sandwiching portion 32b can move the back portion of the handle portion main body 32a. The fastener 32c is an umbrella-shaped member composed of a shaft portion and an umbrella portion.

The driver 10 is sandwiched between the bottom of the handle body 32a and the holding portion 32b, and the holding portion 32b is pressed and fixed to the end of the shaft portion of the fastener 32c to fix the optical sensor 30 to the driver 10. Will be done. As a result, the optical sensor 30 keeps the relative distance of the rotating shaft 12 of the driver 10 from the engaging portion 12a always constant.

Subsequently, the usage state of the level adjusting device 1 for the level indicator will be described with reference to FIG. Reinforcing bars 60 (for example, reinforcing bars of the skeleton) protrude from the top of the skeleton of the foundation that constitutes the building. A fixture 52 is fixed to the reinforcing material 60. A right-hand thread-shaped female thread is formed on the fixture 52. The level indicator 51 is formed as a so-called wing bolt whose upper end is formed in the shape of a butterfly wing. Further, the bolt portion of the wing bolt-shaped level indicator 51 is a right-hand thread-shaped male screw. The level indicator 51 is screwed into the female screw of the fixture 52. As a result, when the level indicator 51 rotates clockwise (arrow A), it moves downward (arrow B), and when the level indicator 51 rotates counterclockwise (arrow C), it moves upward (arrow D). Become. Thereby, the position of the upper end of the level display tool 51 can be determined. The muscle material 60 corresponds to the "support" in the present invention.

In addition, the laser oscillator 3 is set in advance at the construction site of the building. The laser oscillator 3 projects a horizontal laser beam to the surroundings regardless of the tilted state of the set location. This laser light becomes the marking light R (one-dot chain line in FIG. 2) used by the level adjusting device 1 for the level indicator as a horizontal reference.

The engaging portion 12a of the driver 10 of the level adjusting device 1 for the level indicator engages with the upper end of the level indicator 51 and the portion formed in the shape of a butterfly wing. When the sensing area 40 of the optical sensor 30 detects the marking R, the information from the optical sensor 30 is transmitted to the control unit 20. Then, the motor built in the control unit 20 is driven according to the location where the sensing area 40 of the optical sensor 30 senses the marking light R, rotates the rotating shaft 12, and is engaged with the engaging portion 12a. The level indicator 51 is rotated in an arbitrary direction. Thereby, the level of the level display tool 51 can be adjusted.

Subsequently, the level indicator is used with reference to FIGS. 2 showing the usage state, FIGS. 4 and 5 showing the positional relationship between the sensing area 40 of the optical sensor 30 and the marking light R, and FIGS. 6 to 8 of the flowchart showing the program. When the level adjusting device 1 is used and the level adjusting device 1 for the level indicator is used, it is executed by the control unit 20 (hereinafter, also simply referred to as “control unit 20”) of the level adjusting device 1 for the level indicator. Each step to be performed will be described.

When using the level adjusting device 1 for level indicators, first, the user of the level adjusting device 1 for level indicators (not shown, hereinafter simply referred to as "user") is as shown in FIG. , The engaging portion 12a of the rotating shaft 12 is engaged with the level display tool 51 fixed to the muscle member 60 via the fixing tool 52. At this time, the user may attach a spirit level 70 (see FIG. 1) to the fastener 32c of the level indicator 51 to vertically extend the level indicator 51.

Then, the user presses the power button 21 of the level adjusting device 1 for the level indicator. On the other hand, the control unit 20 automatically executes the program recorded on its own recording medium. The control unit 20 that executes this program makes initial settings necessary for executing each step described later, and then proceeds to the process in step S10 of FIG. The initial setting includes a process of setting an upper limit and a lower limit of the rotation speed when the control unit 20 rotates the motor.

In step S10, the control unit 20 turns on the power LED 25. As a result, the user can know that the level adjusting device 1 for the level indicator is activated. After the power LED 25 is turned on, the control unit 20 proceeds to the process in step S20.

In step S20, the control unit 20 sets its own control to the auto mode (that is, the state in which the control is automatically advanced regardless of the operation of the control unit 20 by the user). Further, the control unit 20 lights the auto mode LED 26 (see FIGS. 1 and 2). As a result, the user can know that the level adjusting device 1 for the level indicator is controlled in the auto mode. After the auto mode LED 26 is turned on, the control unit 20 proceeds to the process in step S30.

In step S30, the control unit 20 determines whether or not any of the power button 21, the auto button 22, the ascending button 23, and the descending button 24 (see FIGS. 1 and 2) has been operated. When the power button 21 is operated, the control unit 20 immediately shuts down the level adjusting device 1 for the level indicator. Further, when the determination result in step S30 is "No" (that is, none of the power button 21, the auto button 22, the ascending button 23, and the descending button 24 is operated), the control unit 20 is in the auto mode. Is maintained, and the process proceeds to step S40.

Further, the control unit 20 is in a state of determining that the determination result in step S30 is "Yes" (that is, there is an operation of any one of the auto button 22, the ascending button 23, and the descending button 24. In the case of), the control unit 20 sets the state to the manual mode (that is, the state in which the control is advanced according to the operation of the control unit 20 by the user), and proceeds to the process in step S35.

In step S35, the control unit 20 stops the operation of the built-in sound source. That is, when the sound source oscillates any of the three types of beep sounds, the beep sounds are stopped. After stopping the operation of the sound source, the control unit 20 proceeds to the process in step S50.

In step S50, the control unit 20 determines whether or not the ascending button 23 has been operated. If the determination result in step S50 is "Yes" (that is, the ascending button 23 is pressed), the control unit 20 advances the process to step S60.

If the determination result in step S50 is "No" (that is, the ascending button 23 is not pressed), the control unit 20 advances the process to step S70.

In step S60, the control unit 20 rotates the motor and the rotating shaft 12 built in the control unit 20 counterclockwise to rotate the level indicator 51 engaged with the engaging portion 12a of the rotating shaft 12 counterclockwise (FIG. FIG. 2 arrow C). That is, the level adjusting device 1 for the level indicator raises the level indicator 51 (arrow D in FIG. 2). Then, with the counterclockwise rotation of the motor started, the control unit 20 advances the process to step S90.

In step S70, the control unit 20 determines whether or not the descent button 24 has been operated. If the determination result in step S70 is "Yes" (that is, the descent button 24 is pressed), the control unit 20 advances the process to step S80.

If the determination result in step S70 is "No" (that is, the descent button 24 is not pressed), the control unit 20 advances the process to step S140.

In step S80, the control unit 20 rotates the motor and the rotating shaft 12 built therein to the right, thereby rotating the level indicator 51 engaged with the engaging portion 12a of the rotating shaft 12 to the right (FIG. FIG. 2 arrow A). That is, the level adjusting device 1 for the level indicator lowers the level indicator 51 (arrow B in FIG. 2). Then, with the right rotation of the motor started, the control unit 20 advances the process to step S90.

In step S90, the control unit 20 determines whether or not any of the buttons is fully pressed on the premise that the ascending button 23 or the descending button 24 is pressed. If the determination result in step S90 is "Yes" (either the ascending button 23 or the descending button 24 is held down), the control unit 20 advances the process to step S100.

If the determination result in step S90 is "No" (neither the ascending button 23 nor the descending button 24 is fully pressed), the control unit 20 advances the process to step S120.

In step S100, the control unit 20 determines whether or not the rotation speed of the motor is the maximum speed. That is, the control unit 20 determines whether or not the motor is rotating at the upper limit rotation speed set in the above-mentioned initial setting. If the determination result in step S100 is "Yes" (the rotation speed of the motor is the highest), the control unit 20 advances the process to step S130.

If the determination result in step S100 is "No" (the rotation speed of the motor is not the highest speed), the control unit 20 advances the process to step S110.

In step S110, the control unit 20 raises the setting of the rotation speed of the motor. That is, the control unit 20 sets the rotation speed of the motor to the upper limit rotation speed set in the above-mentioned initial setting. Then, the control unit 20 advances the process to step S130.

In step S120, the control unit 20 sets the rotation speed of the motor to the minimum speed. That is, the control unit 20 sets the rotation speed of the motor to the lower limit rotation speed set in the above-mentioned initial setting. Then, the control unit 20 advances the process to step S130.

In step S130, the control unit 20 controls the rotation of the motor so that the motor rotates at the rotation speed set in step S110 or step S120 executed immediately before. That is, the control unit 20 has the highest speed when it is set to rotate the motor at the maximum speed through step S110, and the lowest speed when it is set to rotate the motor at the lowest speed through step S120. , Rotate the motor. Then, the control unit 20 advances the process to step S50. That is, the control unit 20 maintains the manual mode and repeats each step of the manual mode.

In step S140, the control unit 20 stops the rotation of the motor. After stopping the rotation of the motor, the control unit 20 proceeds to the process in step S150.

In step S150, the control unit 20 determines whether or not the auto button 22 has been operated. If the determination result in step S150 is "No" (that is, the auto button 22 is not pressed), the control unit 20 advances the process to step S30.

If the determination result in step S150 is "Yes" (that is, the auto button 22 is pressed), the control unit 20 advances the process to step S160.

In step S160, the control unit 20 determines whether the control unit 20 is driven in the auto mode or the manual mode. If the determination result in step S160 is "Yes" (that is, the control unit 20 is controlling in the auto mode), the control unit 20 advances the process to step S170.

If the determination result in step S160 is "No" (that is, the control unit 20 is controlling in the manual mode), the control unit 20 advances the process to step S180.

In step S170, the control unit 20 switches the control of the control unit 20 to the manual mode and turns off the auto mode LED 26. As a result, the user can know that the control of the control unit 20 has been switched to the manual mode. After the auto mode LED 26 is turned off, the control unit 20 proceeds to the process in step S50.

In step S180, the control unit 20 switches the control of the control unit 20 to the auto mode and turns on the auto mode LED 26. As a result, the user can know that the control of the control unit 20 has been switched to the auto mode. After the auto mode LED 26 is turned on, the control unit 20 proceeds to the process in step S30.

In step S40, the control unit 20 determines whether or not there is light receiving information, that is, whether or not the marking light R hits the sensing area 40 of the optical sensor 30. If the determination result in step S40 is "No" (the detection area 40 is not exposed to the marking light R), the control unit 20 proceeds to the process in step S30.

When the determination result in step S40 is “Yes” (the detection area 40 is hit by the marking light R), the control unit 20 proceeds to the process in step S190 shown in FIG.

In step S190, the control unit 20 determines whether or not "center detection" is established, that is, whether or not the marking light R hits the central area 43 (see FIG. 3) in the sensing area 40. do. When the determination result in step S190 is "No" (it is determined that the marking light R hits the sensing area 40, but the marking light R does not hit the central area 43), the control unit 20 determines. The process proceeds to step S200.

When the determination result in step S190 is "Yes" (determining that the marking light R hits the central area 43), the control unit 20 proceeds to the process in step S270.

In step S200, the control unit 20 determines whether or not "lower detection" is established, that is, whether or not the marking light R hits the first area 41 (see FIG. 3) in the sensing area 40. judge. If the determination result in step S200 is "Yes" (it is determined that the marking light R hits the first area 41), the control unit 20 advances the process to step S210.

When the determination result in step S200 is "No" (determining that the marking light R does not hit the first area 41), the control unit 20 proceeds to the process in step S230.

In step S210, the control unit 20 rotates the motor built in the control unit 20 counterclockwise. At this time, the control unit 20 raises the level indicator 51 by rotating the rotary shaft 12 connected to the motor counterclockwise together with the level indicator 51 engaged with the engaging portion 12a. .. As a result, the position where the marking light R hits shifts downward from the first area 41 and approaches the central area 43 (see FIG. 4A). Then, at the same time when the control unit 20 starts rotating the motor counterclockwise, it transmits a control signal to the built-in sound source to generate a beep sound A (a buzzer sound during adjustment). After that, the control unit 20 advances the process to step S220. This step S210 corresponds to the "first movement function" in the present invention.

In step S220, the control unit 20 sets that the received light data in the sensing area 40 is "lower detection". That is, the control unit 20 remembers that the marking light R hits the first area 41 to drive the motor. Then, the control unit 20 advances the process to step S30.

In step S230, the control unit 20 determines whether or not "upper detection" is established, that is, whether or not the marking light R hits the second area 42 (see FIG. 3) in the sensing area 40. judge. If the determination result in step S230 is "Yes" (it is determined that the marking light R hits the second area 42), the control unit 20 advances the process to step S240.

When the determination result in step S230 is "No" (determining that the marking light R does not hit the second area 42), the control unit 20 proceeds to the process in step S260. The function realized in the level adjusting device 1 for the level indicator by each step of step S40, step S190, step S200, and step S230 described above corresponds to the "determination function" in the present invention.

In step S240, the control unit 20 rotates the motor built in the control unit 20 clockwise. That is, the level indicator 51 is lowered by rotating it clockwise (arrow A in FIG. 2) together with the rotary shaft 12 connected to the motor and the level indicator 51 engaged with the engaging portion 12a thereof (FIG. 2). 2 arrow B). As a result, the position where the marking light R hits shifts upward from the second area 42 and approaches the central area 43 (see FIG. 5A). Then, at the same time when the control unit 20 starts rotating the motor clockwise, it transmits a control signal to the built-in sound source to generate a beep sound A (a buzzer sound during adjustment). After that, the control unit 20 advances the process to step S250. The function realized in the level adjusting device 1 for the level indicator by this step S240 corresponds to the "second moving function" in the present invention.

In step S250, the control unit 20 sets that the received light data in the sensing area 40 is "upper detection". That is, the control unit 20 remembers that the marking light R hits the second area 42 to drive the motor. Then, the control unit 20 advances the process to step S30.

In step S260, the control unit 20 stops the rotation of the motor and waits until any of the power button 21, the auto button 22, the ascending button 23, and the descending button 24 is operated. Then, when the operation for canceling the standby is performed, the control unit 20 advances the process to step S30. Here, the process of the control unit 20 proceeds to step S260 because the control unit 20 senses the marking light R in the sensing area 40 and enters the control operation, but the marking light R momentarily deviates from the sensing area 40. This is the case when an error occurs, such as when the light is received or when the light receiving information is received for a moment due to noise. That is, according to step S260, in order to prevent the above error, it is possible to stop the rotation of the motor once, put the control unit 20 in the standby state, and then return to the auto mode or the manual mode.

In step S270, the control unit 20 searches for the information stored in the control unit 20, and has the marking light R hit the first area 41 before the marking light R hits the central area 43? Judge whether or not. Whether or not the marking light R hits the first area 41 is determined based on the light receiving data set in step S220. The determination result in step S270 is "Yes" (that is, it is determined that the first area 41 was hit by the marking light R before the central area 43 was hit by the marking light R (after receiving step S220, the marking light R was hit). If the received light data is set to "lower detection")), the control unit 20 proceeds to the process in step S280.

When the determination result in step S270 is "No" (that is, it is determined in step S190 that the marking light R is not hitting the central area 43 before the marking light R hits the central area 43), control is performed. The unit 20 advances the process to step S310.

In step S280, the control unit 20 sets the received light data to "center detection" and starts counting. At this time, the control unit 20 stops the motor after memorizing that the marking light R hits the central area 43, and stops the advance / retreat of the level indicator 51. Then, the control unit 20 starts counting the number of seconds. However, if the number of seconds count in step S280 has already been executed, the control unit 20 does not start the number of seconds count again. Then, the control unit 20 advances the process to step S290. The function realized in the level adjusting device 1 for the level display tool by this step S280 corresponds to the "advance / retreat stop function" in the present invention.

In step S290, the control unit 20 generates a beep sound B (center detection buzzer sound) by outputting a control signal to the built-in sound source. Then, the control unit 20 advances the process to step S300.

In step S300, the control unit 20 hits the central area 43 with the marking light R from the start of the second count in step S280 until the number of seconds set in the initial setting described above elapses. Determine if the state is maintained. When the determination result in step S300 is "Yes" (that is, it is determined that the set number of seconds has elapsed while the marking light R is in contact with the central area 43), the control unit 20 controls step S280. The number of seconds count is stopped, and the process proceeds to step S330 (see FIG. 8).

The determination result in step S300 is "No" (that is, the number of seconds set in the above-mentioned initial setting has not elapsed since the number of seconds count in step S280 was started, or the central area 43 is marked. If it is determined that the light R does not hit), the control unit 20 proceeds to the process in step S30. The control unit 20 stops the number of seconds count in step S280 when proceeding with the process from step S300 to step S30 because "it is determined that the marking light R does not hit the central area 43".

In step S310, the control unit 20 searches for the information stored in the control unit 20, and "upper detection" is established for the data used for the determination in step S190 executed two times before. Whether or not (that is, whether or not the marking light R hits the second area 42 after the marking light R hits the central area 43) is determined. The determination result in step S310 is "Yes" (that is, it is determined that the marking light R hits the second area 42 before the marking light R hits the central area 43 (in response to step S250, the marking light R hits). If the received light data is set to "upper detection")), the control unit 20 proceeds to the process in step S320.

The determination result of step S310 is "No" (that is, the cumulative number of executions of step S190 since the start of the program is 1 or less, or the central area 43 is hit by the marking light R, and then the second step is performed. If it is determined that the area 42 is not exposed to the marking light R (in response to step S280, the received light data is set to "central detection"), the control unit 20 proceeds to the process in step S280.

In step S320, the control unit 20 sets the rotation speed of the motor, which has been rotated clockwise until just before the marking light R hits the central area 43, to be the lower limit rotation speed set in the above-mentioned initial setting. Continue to rotate clockwise. After setting the rotation speed of the motor to the minimum speed, the control unit 20 proceeds to the process in step S30. This step S320 corresponds to the "movement continuation function" in the present invention.

In step S330, the control unit 20 stops the sound emitted by the above-mentioned sound source. Then, the control unit 20 advances the process to step S340.

In step S340, the control unit 20 adjusts the level of the level display tool 51 by transmitting a control signal to the above-mentioned sound source (positioning of the relative position of the level display tool 51 with respect to the reinforcement 60 in the vertical direction). A beep sound C (adjustment completion signal sound), which is a sound indicating that is completed, is generated. Then, the control unit 20 advances the process to step S350.

In step S350, the control unit 20 lights the adjustment completion LED 27 (see FIGS. 1 and 2). Then, the control unit 20 is in a stopped state until a predetermined time set in the above-mentioned initial setting elapses. In this stopped state, the light information (light receiving information) detected by the optical sensor 30 in the sensing area 40 and the operations on the power button 21, the auto button 22, the ascending button 23, and the descending button 24 are ignored. Will be done. Further, in the stopped state, the motor of the control unit 20 stops its operation. The control unit 20 releases the stopped state when the predetermined time elapses after the stopped state, and proceeds to the process in step S360. The functions realized in the level adjusting device 1 for the level indicator by step S350 correspond to the "maintenance function" and the "function stop function" in the present invention.

In step S360, the control unit 20 determines whether or not the marking light R hits the sensing area 40 of the optical sensor 30. If the determination result in step S360 is "Yes" (that is, it is determined that the marking area 40 is hit by the marking light R), the control unit 20 advances the process to step S370.

If the determination result in step S360 is "No" (that is, it is determined that the marking area 40 is not exposed to the marking light R), the control unit 20 does not proceed with the process and repeats the process in step S360. Run.

In step S370, the control unit 20 starts counting the time after the marking light R starts to hit the sensing area 40. However, if the time count in step S370 has already been executed, the control unit 20 does not start the time count again. Then, the control unit 20 advances the process to step S380.

In step S380, the control unit 20 is in a state where the detection area 40 is exposed to the marking light R from the start of the time counting in step S370 until the time set in the above-mentioned initial setting elapses. Determine if it has been maintained. When the determination result in step S380 is "Yes" (that is, it is determined that the set time has elapsed while the marking area 40 is in contact with the marking light R), the control unit 20 determines the time in step S370. The count is stopped, and the process proceeds to step S390.

The determination result in step S380 is "No" (that is, the time set in the above-mentioned initial setting has not elapsed since the time count in step S370 was started, or the marking light R is in the sensing area 40. If it is determined that the above is not hit), the control unit 20 proceeds to the process in step S360. The control unit 20 stops the time count in step S370 when proceeding with the process from step S380 to step S360 because "it is determined that the marking area 40 is no longer hit by the marking light R".

In step S390, the control unit 20 switches the control of the control unit 20 to the auto mode and turns on the auto mode LED. As a result, the user can know that the control of the control unit 20 has returned to the auto mode. Then, the control unit 20 advances the process to step S30.

The level adjusting device 1 for a level indicator used through the above program has the following advantages. First, as shown in FIG. 4, during the process from step S200 to step S210 and step S220, the position of the marking light R corresponding to the sensing area 40 moves from the first area 41 toward the central area 43, and the level indicator 51 is rotated counterclockwise by the driver and approaches the reference line N (see FIG. 4A). Then, when step S30, step S40, step S190, step S270, and step S280 are passed, the position where the marking light R hits stops on the boundary line 43a between the first area 41 and the central area 43, and the level indicator 51 also It reaches the reference line and stops (see FIG. 4B).

On the other hand, as shown in FIG. 5, during the process from step S230 to step S240 and step S250, the position of the marking light R in the sensing area 40 moves from the second area 42 toward the central area 43, and the level is displayed. The upper end of the tool 51 is rotated clockwise by the driver and descends to approach the reference line N (see FIG. 5A). During the steps S30, step S40, step S190, step S270, step S310, and step S320, the position of the sensing area 40 where the marking light R hits continues to move from the central area 43 toward the first area 41. That is, the upper end of the level indicator 51 also descends to approach the reference point and approaches the reference line N (see FIG. 5B). Then, during the process from step S200 to step S210 and step S220, the sensing position on the sensing area 40 of the marking light R moves from the first area 41 toward the central area 43. That is, after the upper end of the level indicator 51 has passed the reference line N once, the level indicator 51 is rotated counterclockwise to rise and approach the reference line N again (see FIG. 5C). Further, when step S30, step S40, step S190, step S270, and step S280 are passed, the position where the marking light R hits stops on the boundary line 43a between the first area 41 and the central area 43, and the level indicator 51 Also stops on the reference line N (see FIG. 5D). That is, the position where the marking light R hits always stops at the boundary line 43a, and the upper end of the level indicator 51 can be stopped on the reference line N. That is, it is expected that the level adjustment accuracy of the level display tool 51 will be improved.

Further, in response to the fact that the adjustment completion LED 27 is turned on in step S350, the user of the level adjusting device 1 for the level indicator removes the engaging portion 12a from the level indicator 51 and adjusts another level indicator. While going to, the motor does not rotate even if the marking light R hits the sensing area 40, and the position of the level indicator 51 once adjusted is not shifted. Therefore, the level adjusting device 1 for the level indicator can be quickly detached from the level indicator 51 for which the level adjustment has been completed.

By returning to the auto mode from step S370 through step S390, the level of the level indicator is adjusted again after engaging the engaging portion 12a of the level adjusting device 1 for the level indicator with the new level indicator. Will be able to. Therefore, after adjusting the level of the level indicator 51, it is possible to smoothly adjust the level of another level indicator.

[Other Embodiments]
The present invention is not limited to the above-described embodiment using figures, flowcharts, and the like, and various changes, additions, and deletions can be made without changing the gist of the present invention. That is, the above-described embodiment was used at the construction site of the foundation of the building, but the "construction" in the present invention is a concept including both the building and the structure, and is necessary for both. The present invention can be applied in. For example, as a building, it can be applied not only to the foundation process but also to a process in which the height needs to be constant, and can also be applied to the adjustment of the distance of the equipment for keeping the distance from the ceiling constant. Further, the present invention can also be applied to the adjustment of the distance of the appliance for keeping the distance from the skeleton wall to the interior wall constant in the puffer wall construction method in which the interior wall is attached to the skeleton wall via a columnar mounting member. .. As for the structure, the shape of the structure to be constructed does not matter. For example, it can be applied to the adjustment of the distance of the equipment for correcting the unevenness of the base layer on the paved road, the adjustment of the position of the boundary marker that defines the section, the adjustment of the unevenness of the side wall of the road, and the like.

Further, although the "support" in the present invention corresponds to the "muscle material" in the above-described embodiment, any one may be used as long as it exists at a fixed position and serves as a reference for positioning the level indicator. .. For example, the skeleton of the foundation, the foundation itself, and the ground on which the structure is constructed are also included.

Further, although the control unit 20 is provided in a state of being separated from the driver 10 and the optical sensor 30, the control unit may be provided in a state of being integrated with either the driver 10 or the optical sensor 30. Alternatively, control units may be provided on both the driver 10 and the optical sensor 30 to control the driver 10 and the optical sensor 30 in cooperation with each other.

Further, in the present embodiment, the control unit 20 and the optical sensor 30 are connected by wire, but the wired connection between the two is not essential, and the control unit 20 may control the optical sensor 30 wirelessly.

Further, in the present embodiment, the upper side is "one side" and the lower side is "the other side", but the upper side is set as "the other side" and the lower side is set as "one side", and the "first area 41" is set. May be set to "second area" and "second area 42" may be set to "first area".

Further, in the above-described embodiment, the vertical direction is defined as "one direction", but if the approach direction is to enter the support of the structure or the separation direction is opposite to the approach direction, the direction is particularly different. Not determined. For example, when the direction of entering the support is the lateral direction, the direction is the lateral direction.

Further, although the bolt portion of the level indicator 51 has a right-handed screw shape in the embodiment, it may have a left-handed screw shape. Further, the shape of the level indicator 51 does not have to be a wing bolt shape, and any shape may be used as long as it can advance and retreat in the vertical direction with respect to the reinforcing material 60. Further, although the upper end of the level indicator 51 is used as a reference for the top edge of the foundation, the lower end may be used as a reference for the top edge of the foundation.

Further, the fixture 52 in the embodiment is attached to the muscle member 60 protruding from the skeleton of the foundation, but if the level indicator 51 can be fixed, the fixture 52 may take various shapes regardless of the shape. Is possible. For example, the level indicator 51 may be attached to the foundation skeleton by embedding it in the foundation skeleton.

Then, the shape of the engaging portion 12a can be variously changed according to the shape of the level display tool 51. For example, when the upper end of the level display tool 51 is hexagonal, the engaging portion 12a can also be hexagonal to match the shape.

Further, the one direction in which the level display tool 51 is moved forward and backward may be different when the target to which the level display tool 51 is attached is a "support" other than the reinforcement 60. For example, when the level indicator is for positioning the distance from the ceiling of the building to be constant, the distance from the wall of the building is constantly positioned, although it is in the vertical direction as in the above-described embodiment. If it is a thing, it may be a lateral direction, or if it is a thing that positions a constant distance from a slope or the like, it may be an oblique direction.

Further, the sensing area 40 in the embodiment is composed of the upper sensing unit 40a and the lower sensing unit 40b, but this configuration is not limited. For example, it may be composed of one connected sensing unit, and the first area 41, the central area 43, and the second area 42 may be set according to the detected portion.
