  By the way, as described above, a positioning sensor for positioning the position of the pallet is arranged in each parking section in the parking apparatus. As the positioning sensor, a contact type mechanical limit switch, a non-contact type magnetic sensor, a photoelectric sensor, or the like is used, and these are connected to a control panel. This positioning sensor is checked for operation during maintenance or trouble. The operation confirmation requires at least two workers because the installation location of the positioning sensor and the installation location of the control panel for confirming the operation of the positioning sensor are separated. That is, one worker checks whether or not the positioning sensor is manually turned on at the location where the positioning sensor is installed, or whether the sensor is turned on, and the other worker places the positioning sensor at the location where the control panel is installed. The operation of each sensor is confirmed by confirming the LED (Light Emitting Diode) that lights up when it is turned on. At this time, the two workers confirm the operation of the sensor one by one by talking to each other.

  However, the number of positioning sensors increases depending on the form of the parking device. For example, an 8-stage, 8-stage multi-stage parking apparatus includes at least 64 positioning sensors. In addition to this positioning sensor, the parking device has a fall prevention device that prevents the lifting pallet from falling, an emergency limit switch that detects an overrun of the lifting pallet and makes an emergency stop, and a change in the movement speed of the pallet. There are many types of sensors, such as an intermediate limit switch that determines the position, and a thermal switch that detects overcurrent by temperature and shuts off the drive current when the motor is overloaded. Therefore, it takes time to check the operation of these sensors. Furthermore, as described above, since the operation of the sensor is confirmed by two workers talking to each other, the positioning sensor actually confirmed by one worker and the other operator confirming with the control panel In some cases, the LED of the positioning sensor is different.

1. 1st Embodiment Hereinafter, an example of the operation panel of the parking apparatus which can confirm the operation | movement of a positioning sensor for every pallet is demonstrated.

(Configuration of parking device)
FIG. 1 is a front view showing an example of a parking apparatus provided with a pallet positioning sensor. The parking device 1 is a multistage mechanical parking device configured by three stages and three stations. The entry / exit floor of the parking device 1 is the first floor above the ground, and the parking device 1 moves the target pallets P01 to P08 to the entry / exit floor according to instructions from the operation panel 2. The parking apparatus 1 includes elevating pallets P01 to P03 and P06 to P08 that move up and down to the entry / exit floor and traversing pallets P04 to P05 that traverse the entry / exit floor from side to side.

  The elevating pallets P01 to P03 move up and down between the first basement floor and the entry / exit floor, and the elevating pallets P06 to P08 move up and down between the second floor and the entry / exit floor. The lifting pallets P01 to P03 and P06 to P08 connect a suspension chain to four corners, and the suspension chain is connected to a drive shaft of a pallet lifting motor via a sprocket. When the pallet lifting / lowering motor rotates, the lifting pallets P01 to P03 and P06 to P08 connected to the suspension chain move up and down.

  The traversing pallet P04 traverses between one station (the leftmost column in FIG. 1) and two stations (the center column in FIG. 1) on the entry / exit floor, and the traversing pallet P05 includes two stations and three stations on the entry / exit floor ( The rightmost column in FIG. The traversing pallets P04 and P05 are provided with traversing rollers, and the traversing rollers rotate on traversing rails provided in the parking apparatus 1. The traverse roller is rotated by a pallet traverse motor provided in the traverse pallets P04 and P05. When the pallet traversing motor rotates, the traversing roller rotates on the traversing rail, and the traversing pallets P04 and P05 traverse to the left and right.

  In addition, the parking device 1 includes positioning sensors LS01 to LS09 that position the position of the pallet. FIG. 2 is an explanatory diagram for explaining a pallet positioning sensor. The positioning sensors LS01 to LS09 are magnetic sensors composed of Hall elements H having an input terminal and an output terminal. In the Hall element H, when a magnetic field B is applied in the Y direction with a constant current I flowing in the input terminal, electrons in the Hall element H receive Lorentz force (electromagnetic force) and the direction of the constant current I And the Z direction perpendicular to the direction of the magnetic field B. For this reason, a potential difference is generated at the output terminal of the Hall element, and an output voltage V is generated. The magnetic field B applied to the Hall element H is generated by a magnet provided on the outer surface of the pallet. Therefore, when the magnet provided on the pallet approaches the positioning sensors LS01 to LS09, the magnetic field B is generated and the output voltage V is generated. When the output voltage V is greater than or equal to the predetermined value, the positioning sensors LS01 to LS09 output an on signal, and when the output voltage V is less than the specified value, the positioning sensors LS01 to LS09 output an off signal.

  The transverse pallet P04 and the transverse pallet P05 share the positioning sensor LS05. Therefore, in order to determine whether the on / off signal of the positioning sensor LS05 is from the transverse pallet P04 or the transverse pallet P05, the transverse pallet P04 is provided with an N-pole magnet, and the transverse pallet P05 has S A pole magnet is provided. Since the transverse pallet P04 and the transverse pallet P05 are provided with magnets having opposite polarities, the direction of the magnetic field of the Hall element and the polarity of the output voltage change. Therefore, based on the polarity of the output voltage, the transverse pallet P04 and the transverse pallet P05 are Can be determined.

  On the other hand, the lifting pallets P01 to P03, P06 to P08 and the transverse pallets P04 and P05 share the positioning sensors LS04 to LS06. Therefore, in order to discriminate between the lifting pallets P01 to P03 and P06 to P08 and the transverse pallets P04 and P05, a positioning sensor that outputs an off signal is detected. For example, when the elevating pallet P08 shown in FIG. 1 is descending on the entry / exit floor, the positioning sensor LS06 is turned on. In this case, whether the ON signal of the positioning sensor LS06 is from the lift pallet P08 or the traverse pallet P05 is determined to be from the lift pallet P08 when the positioning sensor LS09 is an OFF signal, and positioning is performed. When the sensor LS09 is an ON signal, it is determined that the sensor is based on the transverse pallet P05.

  The lifting pallets P01 to P03 and P06 to P08 are provided with positioning sensors at the positions of the rising end and the falling end. For example, in the case of the pallet P08, the positioning sensor LS09 is provided at the rising end, and the positioning sensor LS06 is provided at the falling end. When the pallet P08 shown in FIG. 1 descends to the entry / exit floor, the positioning sensor LS09 becomes an off signal. When the positioning sensor LS06 outputs an ON signal, the pallet P08 stops at the loading / unloading floor. On the other hand, the horizontal pallets P04 and P05 are provided with positioning sensors at the positions of the right row end and the left row end. For example, in the case of the pallet P05, the positioning sensor LS06 is provided at the right row end, and the positioning sensor LS05 is provided at the left row end. When the pallet P05 shown in FIG. 1 moves to the right, the positioning sensor LS05 is turned off. When the positioning sensor LS06 outputs an ON signal, the pallet P05 stops.

(Configuration of operation panel)
Hereinafter, the configuration of the operation panel 2 for operating the parking device 1 will be described. FIG. 3 is a front view showing an operation panel of the parking device, and FIG. 4 is a block diagram showing a control system of the parking device. The operation panel 2 has a function of moving the target pallet to the entry / exit floor. The operation panel 2 includes an operation unit 3, an operation power switch 4, an emergency stop button 5, a number input unit 6, a display unit 7, and a control unit 10.

  The operation unit 3 is an operation panel for operating the entering / exiting operation of the parking device 1. The operation unit 3 arranges a lighting lamp and operation buttons for each operation procedure. The “power key SW” of the operation unit 3 is a lighting lamp that lights up when the parking apparatus 1 is powered on. The parking apparatus 1 is turned on by inserting an operation key into the operation power switch 4 and turning it from “OFF” to “ON”. The “safety device button” of the operation unit 3 is an operation button for closing the gate. The “calling number input” of the operation unit 3 is a lighting lamp that prompts the user to input a pallet number (calling number). “Start” of the operation unit 3 is an operation button for starting the movement of the pallet to the entry / exit floor. The moved pallet can be urgently stopped by the emergency stop button 5.

  The number input unit 6 is an input button for inputting a pallet number. The number input by the number input unit 6 is displayed on the display unit 7. The display unit 7 includes a total of five 7-segment LEDs 7a to 7e, one each for “row”, “ream”, and “stage” and two for “code”. The “row” 7-segment LED 7a displays the row number where the pallet is located when the parking apparatus 1 includes a plurality of rows of parking sections in the depth direction. The “sequential” 7-segment LED 7b displays the serial number where the pallet is located when the parking apparatus 1 includes a plurality of parking sections in the horizontal direction. The “stage” 7-segment LED 7c displays the stage number where the pallet is located when the parking apparatus 1 includes a plurality of parking sections in the vertical direction.

  The control unit 10 is a semiconductor integrated circuit including a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), a timer, and an input / output port. The control unit 10 reads out a control program stored in the ROM to the RAM, and executes the control program by the CPU. When the pallet number is input from the number input unit 6, the control unit 10 displays the pallet number on the 7-segment LED 7d and the 7-segment LED 7e of the display unit 7. The number of 7-segment LEDs for displaying the pallet number is determined according to the number of pallets in the parking device. In addition, when the control unit 10 receives a start button signal from the operation unit 3, the control unit 10 transmits an operation signal to the control panel 8 that controls the motor that drives the pallet.

  The control panel 8 detects on / off signals of the positioning sensors LS01 to LS09, and performs inverter control of the forward / reverse rotation and the rotation speed of the motors M01 to M08. The control panel 8 to which the operation signal is input from the control unit 10 of the operation panel 2 drives the pallet lifting motors M01 to M03, M06 to M08 or the pallet traverse motors M04 and M05, and the on / off signals of the positioning sensors LS01 to LS09. Is detected. When the positioning sensors LS01 to LS09 output an on signal, the control panel 8 stops driving the motors M01 to M08.

(Positioning sensor operation check)
Hereinafter, the operation check of the positioning sensor on the operation panel 2 will be described. FIG. 5 is a flowchart of a control program for confirming the operation of the positioning sensor. When the operator inputs a password for confirming the operation of the sensor to the number input unit 6 of the operation panel 2, the control unit 10 reads the control program from the ROM and causes the CPU to execute it. Thereafter, when the number input unit 6 inputs the pallet number (step S1), the 7-segment LED 7d and the 7-segment LED 7e of the display unit 7 display the pallet number (step S2). Moreover, the control part 10 makes the control panel 8 detect the ON / OFF signal of the positioning sensor relevant to the pallet of the pallet number (step S3). When the ON / OFF signal of the positioning sensor received by the control unit 10 from the control panel 8 is ON (YES in step S4), the segment corresponding to the positioning position of the positioning sensor is selected from the segments of the 7-segment LED 7a. Lights up (step S5).

  Hereinafter, the correspondence between the segment of the 7-segment LED 7a and the positioning sensor will be described. FIG. 6 is a segment diagram (A) of a 7-segment LED and a correspondence diagram (B) between the segment and the sensor. The segments of the 7-segment LED 7a are SEG1 to SEG7, and SEG1 is located at the upper end of the 7-segment LED 7a. Lights when on. Since SEG4 is located at the lower end of the 7 segment LED 7a, it lights up when the positioning sensors LS01 to LS03 and LS04 to LS06 at the descending ends of the lift pallets P01 to P03 and P06 to P08 are on. Since SEG3 is located at the right end of the 7 segment LED 7a, it lights up when the positioning sensors LS05 to LS06 at the right end of the horizontal pallets P04 to P05 are on. Since SEG5 is located at the left end of the 7 segment LED 7a, it lights up when the positioning sensors LS04 to LS05 at the left end of the horizontal pallets P04 to P05 are on. Note that the on / off states of the positioning sensors LS05 to LS06 at the right row ends of the transverse pallets P04 to P05 may be displayed not on SEG3 but on SEG2. Further, the on / off states of the positioning sensors LS04 to LS05 at the left end of the traversing palettes P04 to P05 may be displayed not on SEG5 but on SEG6.

  A specific example of the flowchart of FIG. 5 is shown in FIG. FIG. 7 is a diagram illustrating a display unit that displays an on / off state of a pallet positioning sensor. In the case of the parking apparatus 1 shown in FIG. 1, when the number input unit 6 inputs the pallet number “01” (step S1), the 7-segment LED 7d and the 7-segment LED 7e display the pallet number “01” (step S2). . Then, the control unit 10 causes the control panel 8 to detect ON / OFF signals of the rising end positioning sensor LS04 and the falling end positioning sensor LS01 related to the pallet of the pallet number “01” (step S3). In the case of FIG. 1, since the positioning sensor LS01 at the lower end is on (YES in step S4), the SEG4 of the 7 segment LED 7a corresponding to the positioning position of the positioning sensor LS01 is lit (step S5). On the other hand, since the rising end positioning sensor LS04 is OFF (NO in step S4), SEG1 of the 7-segment LED 7a is not lit.

  When the number input unit 6 inputs the pallet number “05” (step S1), the 7-segment LED 7d and the 7-segment LED 7e display the pallet number (step S2). Then, the control unit 10 causes the control panel 8 to detect on / off signals of the left side end positioning sensor LS05 and the right side end positioning sensor LS06 of the traversing pallet P05 (step S3). In the case of FIG. 1, since the positioning sensor LS05 at the left row end is on (YES in step S4), the SEG5 of the 7 segment LED 7a corresponding to the left row end positioned by the positioning sensor LS05 is turned on (step S5). On the other hand, since the positioning sensor LS06 at the right end is off (NO in step S4), SEG3 of the 7-segment LED 7a is not lit. Thus, the pallet number is displayed on the 7-segment LED 7d and the 7-segment LED 7e, and the on / off state of the positioning sensor related to the pallet is displayed on the 7-segment LED 7a.

(Pallet position check)
Furthermore, when it is known that all the positioning sensors related to the pallet are normal, the actual position of the pallet can be confirmed using the operation panel 2 according to the present invention. Further, when all the positioning sensors related to the pallet are off, it is possible to confirm that the pallet is stopped at an abnormal position.

  A specific example is shown in FIG. FIG. 8: is a front view (A) which shows the parking apparatus which the pallet stopped emergency, and a figure (B) which shows the display part which displays the on-off state of the positioning sensor of a pallet. The pallet P04 and pallet P05 shown in FIG. 8 are in an emergency stopped state. At this time, when the number input unit 6 inputs the pallet number “04” (step S1), the 7-segment LED 7d and the 7-segment LED 7e display the pallet number “04” (step S2). The control unit 10 causes the control panel 8 to detect the on / off signals of the positioning sensor LS05 at the left row end and the positioning sensor LS04 at the right row end of the pallet P04 with the pallet number “04” (step S3). In the case of FIG. 8A, since the positioning sensor LS05 and the positioning sensor LS04 are both off (NO in step S4), the control unit 10 does not light any segment of the 7-segment LED 7a.

  For this reason, when it is known that the positioning sensors LS04 to LS05 are normal, it is understood that the pallet P04 is stopped at an abnormal position. This aspect is particularly effective in the case of a multi-row parking apparatus having a large number of pallets and a large number of pallets. In the case of a double row parking device, the position of the pallet in the rear row may be blocked by a vehicle parked on the pallet in the front row and may not be visually confirmed. For this reason, the ON / OFF state of the positioning sensor of the rear pallet is displayed on the display unit 7 of the operation panel 2, so that the position of the pallet can be easily confirmed. On the other hand, the same applies to a multistage parking apparatus having a large number of pallets, which is suitable for checking the position of a pallet in a place where visual confirmation is not possible.

(Advantages of the first embodiment)
The parking device includes a large number of sensors. As the number of pallets in the parking device increases, the number of sensors also increases. Therefore, in the case of a relatively large parking device, it takes time to check the operation of the sensor. However, according to the first embodiment, the operation of the positioning sensor can be confirmed for each pallet. For this reason, it becomes difficult for the operator to misidentify the positioning sensor, and the operation can be easily confirmed.

  The 7-segment LED 7a displays the on / off state of the pallet positioning sensors LS01 to LS09 on the segments (SEG1 to SEG7) corresponding to the positioning positions of the positioning sensors LS01 to LS09. For this reason, the operator can easily identify the positioning sensors related to the pallet.

  In addition, since the operation panel is generally installed in a place where the operator can easily see the position of the pallet, the operator determines whether the positioning sensor related to the pallet should be on or off. It can be grasped based on the actual position. For this reason, according to the operation panel 2 according to the present invention, the operation of the positioning sensor can be confirmed by one person. On the contrary, when it is known that all the positioning sensors related to the pallet are normal, the actual position of the pallet can be grasped using the operation panel 2 according to the present invention. This aspect is particularly effective in the case of a multi-row parking apparatus in which the operator cannot visually confirm the actual position of the pallet or a parking apparatus having a large number of pallets.

2. 2nd Embodiment Hereinafter, an example of the operation panel of the parking apparatus which can confirm operation | movement confirmation of a fall prevention apparatus for every raising / lowering pallet is demonstrated.

(Configuration of fall prevention device)
The fall prevention device is a safety device that prevents the pallet from falling when a hanging chain or a wire breaks. FIG. 9 is a cross-sectional view showing a cross section of the fall prevention device, and FIG. 10 shows a front view (A) showing a parking device equipped with the fall prevention device and a display unit that displays an on / off state of the fall prevention device. It is a figure (B). The fall prevention device 13 is installed on the support column of the parking device, and is provided at four corners of the lifting pallet 11. The fall prevention device 13 includes a pallet receiving portion 14 and a solenoid 15. The pallet receiving portion 14 has a function of receiving the U-shaped hook 12 of the lifting pallet 11 and is rotated by the movable iron core 16 of the solenoid 15. When a voltage is applied to the coil 17 of the solenoid 15, the movable iron core 16 is attracted to the fixed iron core 18 by electromagnetic force, and the pallet receiving portion 14 goes out of the fall prevention device 13. On the other hand, when no voltage is applied to the coil 17 of the solenoid 15, the movable iron core 16 is separated from the fixed iron core 18 by the elastic force of the spring, and the pallet receiving portion 14 enters the fall prevention device 13.

  The pallet receiving part 14 is stored inside the fall prevention device 13 when the elevating pallet 11 is moving, and projects outside the fall prevention device 13 when the elevating pallet 11 is stopped. At this time, the pallet receiving portions 14 of the four fall prevention devices 13 provided at the corners of the elevating pallet 11 rotate simultaneously. Further, the operation confirmation switch 19 is turned on and off by rotating the pallet receiving portion 14. The operation check switches 19 of the four fall prevention devices 13 are connected in series and output an ON signal when all the operation check switches 19 are turned on.

  The parking device 20 illustrated in FIG. 10A includes fall prevention devices FP01 to FP06. The fall prevention devices FP01 to FP06 are connected to the control panel 8 as shown in FIG. 4, and the control panel 8 detects the on / off signals of the operation confirmation switches of the fall prevention devices FP01 to FP06 to detect the fall prevention devices FP01 to FP01. The FP06 is driven.

(Operation check of the fall prevention device)
Hereinafter, the operation check of the fall prevention device in the operation panel 2 will be described. The confirmation of the operation of the fall prevention device is the same step as the flowchart of the control program for confirming the operation of the positioning sensor shown in FIG. When the operator inputs a password for confirming the operation of the sensor to the number input unit 6 of the operation panel 2, the control unit 10 reads the control program from the ROM and causes the CPU to execute it. Thereafter, when the number input unit 6 inputs the pallet number (step S1), the 7-segment LED 7d and the 7-segment LED 7e of the display unit 7 display the pallet number (step S2). Further, the control unit 10 causes the control panel 8 to detect an on / off signal of an operation confirmation switch of the fall prevention device that prevents the pallet of the pallet number from dropping (step S3). And when the ON / OFF signal of the operation confirmation switch received by the control unit 10 from the control panel 8 is ON (YES in Step S4), it corresponds to the installation position of the fall prevention device in the segment of the 7-segment LED 7a. The segment LED is turned on (step S5).

  FIG. 6 shows the correspondence between the segments of the 7-segment LED 7a and the fall prevention device. In the fall prevention device, in order to prevent the lifting pallet at the rising end position from falling, the segments (SEG2 and SEG6) located below the segment (SEG1) indicating the ON / OFF state of the positioning sensor at the rising end are the fall prevention device. Displays the on / off status of the operation confirmation switch. In addition, as an aspect which displays the on / off state of the operation confirmation switch of the fall prevention device, not only an aspect in which SEG2 and SEG6 are turned on and off simultaneously, an aspect in which one of SEG2 and SEG6 is turned on and off, and an aspect in which only SEG7 is turned on and off But you can.

  A specific example of a mode in which SEG2 and SEG6 are turned on and off simultaneously is shown in FIG. In the case of the parking device 20 shown in FIG. 10A, when the number input unit 6 inputs the pallet number “01” (step S1), the 7-segment LED 7d and the 7-segment LED 7e of the display unit 7 have their pallet number “01”. Is displayed (step S2). Then, the control unit 10 causes the control panel 8 to detect an on / off signal of an operation confirmation switch of the fall prevention device FP01 that prevents the pallet with the pallet number “01” from dropping (step S3). In the case of FIG. 10A, since the operation confirmation switch of the fall prevention device FP01 is an off signal (NO in step S4), the control unit 10 does not light SEG2 and SEG6 of the 7-segment LED 7a.

  On the other hand, when the number input unit 6 inputs the pallet number “06” (step S1), the display unit 7 displays the pallet number “06” (step S2). Then, the control unit 10 causes the control panel 8 to detect an on / off signal of an operation confirmation switch of the fall prevention device FP04 that prevents the pallet of the pallet number “06” from dropping (step S3). In the case of FIG. 10A, the control unit 10 inputs the ON signal of the operation confirmation switch of the fall prevention device FP04 from the control panel 8 (YES in step S4), and therefore corresponds to the installation position of the fall prevention device FP04. The SEG2 and SEG6 of the 7 segment LED 7a are turned on (step S5).

  The display unit 7 may be configured to display the on / off signal of the pallet positioning sensor and the on / off signal of the operation confirmation switch of the fall prevention device on separate 7-segment LEDs. For example, the on / off state of the pallet positioning sensor is displayed on the 7-segment LED 7a, and the on / off state of the operation check switch of the fall prevention device is displayed on the 7-segment LED 7b. According to this aspect, it is difficult for an operator to mistake the positioning sensors LS01 to LS09 and the fall prevention devices FP01 to FP06. In particular, it becomes easy to distinguish between the on / off states of the positioning sensors LS04 to LS06 at the right and left ends of the transverse pallets P04 to P05 and the on / off states of the operation check switches of the fall prevention devices FP01 to FP06.

(Advantage of the second embodiment)
According to the second embodiment, it is possible to confirm the operation of the fall prevention devices FP01 to FP06 for each of the lift pallets P01 to P03 and P06 to P08. The fall prevention devices FP01 to FP06 operate to prevent the elevating pallets P01 to P03 and P06 to P08 from falling when the elevating pallets P01 to P03 and P06 to P08 are at the ascending end. For this reason, the segments (SEG2, SEG6, SEG7) located below the segment (SEG1) indicating the on / off state of the positioning sensors LS04-LS06, LS07-LS09 at the rising ends of the lift pallets P01-P03, P06-P08 are used. By displaying the on / off states of the operation confirmation switches of the fall prevention devices FP01 to FP06, the fall prevention devices FP01 to FP06 and the positioning sensors LS01 to LS09 can be easily identified. Therefore, the operator can easily check the operation of the fall prevention devices FP01 to FP06.

  In addition, as modes for displaying the on / off states of the operation confirmation switches of the fall prevention devices FP01 to FP06, modes in which SEG2 and SEG6 are turned on and off simultaneously (see FIG. 6), modes in which one of SEG2 and SEG6 is turned on and off, only SEG7 There are three modes of turning on and off. According to the mode in which SEG2 and SEG6 are turned on and off at the same time, the position sensors LS01 to LS09 and the fall are used in order to recall an image in which the fall prevention device (SEG2 and SEG6) supports the elevating pallet (SEG1) at the rising end position. It becomes difficult to misidentify the prevention devices FP01 to FP06. On the other hand, when there are a large number of sensors to be checked for operation, a mode in which one of SEG2 or SEG6 is turned on or off or a mode in which only SEG7 is turned on or off is preferable.

3. Third Embodiment Hereinafter, an example of an operation panel of a parking apparatus capable of confirming the operation of a gate positioning sensor will be described.

(Gate configuration)
FIG. 11: is a front view (A) which shows the parking apparatus provided with the positioning sensor of a gate, and the figure (B) which shows the display part which displays the on-off state of the positioning sensor of a gate. The parking device 30 includes a gate 31 on the entry / exit floor. The gate 31 is a safety device that prevents a person from entering the parking device 30 during the operation of the parking device 30 and prevents the vehicle parked in the parking device 30 from being easily stolen or vandalized. The gate 31 has a suspension chain coupled to both ends thereof, and the suspension chain is coupled to the drive shaft of the gate motor via a sprocket. When the gate motor rotates, the gate 31 moves up and down. A positioning sensor LS10 is installed at the descending end of the gate 31, and a positioning sensor LS11 is installed at the ascending end of the gate 31.

(Confirmation of gate positioning sensor operation)
The operation confirmation of the gate positioning sensor on the operation panel 2 will be described below. The operation confirmation of the positioning sensor of the gate is the same step as the flowchart of the control program for confirming the operation of the positioning sensor shown in FIG. When the operator inputs a password for confirming the operation of the sensor to the number input unit 6 of the operation panel 2, the control unit 10 reads the control program from the ROM and causes the CPU to execute it. Thereafter, when the number input unit 6 inputs the gate number (step S1), the 7-segment LED 7d and the 7-segment LED 7e of the display unit 7 display the gate number (step S2). Further, the control unit 10 causes the control panel 8 to detect an on / off signal of the positioning sensor of the gate having the gate number (step S3). When the ON / OFF signal of the positioning sensor received by the control unit 10 from the control panel 8 is ON (YES in step S4), the segment corresponding to the positioning position of the positioning sensor is selected from the segments of the 7-segment LED 7a. Lights up (step S5).

  Since the gate positioning sensors are the rising end and the falling end, the lighting segments of the 7-segment LED 7a are SEG1 and SEG4. A specific example is shown in FIG. In the case of the parking device 30 shown in FIG. 11A, when the number input unit 6 inputs the gate number “91” (step S1), the 7-segment LED 7d and the 7-segment LED 7e of the display unit 7 have their gate numbers “91”. Is displayed (step S2). Then, the control unit 10 causes the control panel 8 to detect on / off signals of the rising end positioning sensor LS11 and the falling end positioning sensor LS10 of the gate number "91" (step S3). In the case of FIG. 11A, since the lower end positioning sensor LS10 is on (YES in step S4), the SEG4 of the 7-segment LED 7a corresponding to the positioning position of the positioning sensor LS10 is turned on (step S5). On the other hand, since the positioning sensor LS11 at the rising end is turned off (NO in step S4), SEG1 of the 7-segment LED 7a is not lit.

  The on / off state of the gate positioning sensor, the on / off state of the pallet positioning sensor, and the on / off signal of the operation check switch of the fall prevention device may be displayed on separate 7-segment LEDs. For example, the on / off state of the pallet positioning sensor is displayed on the 7-segment LED 7a, the on / off state of the operation check switch of the fall prevention device is displayed on the 7-segment LED 7b, and the on / off state of the gate positioning sensor is displayed on the 7-segment LED 7c. indicate. According to this aspect, since the 7-segment LED for operation confirmation is assigned to each of the pallet positioning sensor, the gate positioning sensor, and the fall prevention device, the operation can be easily confirmed without misidentifying them.

(Advantage of the third embodiment)
According to the third embodiment, the operation of the positioning sensors LS10 to LS11 can be confirmed for each gate. This aspect is effective when there are a plurality of gates. In addition, since the on / off states of the positioning sensors LS10 to LS11 are displayed corresponding to the positions to be positioned by the positioning sensors, the operator can easily identify the positioning sensors related to the gate, and confirm the operation. It can be done easily.
