Description

  The present invention relates to a mechanical parking apparatus.

  A mechanical parking device is known as a device that can store a large number of vehicles in a storage space formed in a building.

  As one of the mechanical parking devices, there is an elevator-type mechanical parking device that transports a vehicle between a storage / shelf unit and a storage shelf by a transporter while the vehicle is placed on a pallet.

  A conventional elevator-type mechanical parking apparatus includes a loading / unloading section inside a building, and a wall surface of the building is provided with a loading / unloading port communicating with the loading / unloading section. The entrance / exit is provided with a door that can be opened and closed. In addition, an operation panel is provided in the vicinity of the entrance / exit on the outside of the building.

  In this type of elevator-type mechanical parking device, when a warehousing operation is performed on the operation panel, a pallet called from the storage shelf is placed in the warehousing / unloading section, and then the door of the warehousing / exiting door is opened. In this state, the user enters the warehousing target vehicle into the warehousing unit through the warehousing port, and stops the vehicle on the pallet.

  By the way, in the elevator-type mechanical parking device, a warehousing range is set for the stop position of the vehicle on the pallet. The warehousing range is a range in which it is possible to carry the vehicle between the loading / unloading unit and the storage shelf by the vehicle carrier and that the vehicle being transported does not interfere with the internal structure of the parking device. is there.

  Therefore, when the vehicle is received, it is necessary to stop the vehicle so as to be within the warehousing range on the pallet of the storage / exit section.

  Therefore, conventionally, in addition to the mirror for the user (driver) to check the position of the vehicle on the back wall of the loading / unloading section that is the front as viewed from the loading / unloading port, A lightning stop position indicator lamp is provided for instructing “forward”, “stop”, and “reverse”. Furthermore, in the loading / unloading section, human / vehicle sensors are provided at positions on the left and right sides of the end on the loading / unloading port side and the end on the counter-loading / unloading port side of the warehousing range. Thereby, the said stop position indicator light is made to instruct | indicate a vehicle position to the user of a vehicle based on the data of the vehicle position detected by the said human presence and vehicle sensor (for example, refer patent document 1). ).

  For example, when a vehicle that has entered the loading / unloading section from the loading / unloading port advances onto the pallet, if the rear end of the vehicle protrudes from the end of the loading / unloading port side of the warehousing range, The vehicle body (vehicle) is detected by the human sensor / vehicle sensor. Therefore, while the vehicle body (vehicle) is detected by the human sensor / vehicle sensor at the entrance / exit, the stop position indicator lamp gives a “forward” instruction.

  Thereafter, when the rear end side of the vehicle passes through the end of the warehousing range on the entrance / exit port side as the vehicle progresses onto the pallet, the body / vehicle sensor on the entrance / exit port side no longer detects the vehicle body. At this time, if the vehicle body is not detected even by the human sensor / vehicle sensor on the side opposite to the entrance / exit, the vehicle is within the entry possible range. Therefore, in this state, the “stop” instruction is given by the stop position indicator lamp.

  Furthermore, when the front end side of the vehicle that has traveled onto the pallet protrudes from the end portion on the side opposite to the entrance / exit of the entry range, the vehicle body (vehicle) is detected by the human sensor / vehicle sensor on the side opposite to the entrance / exit. Therefore, the “reverse” instruction is given by the stop position indicator light.

Japanese Patent Application Laid-Open No. 2015-135042

  However, in the mechanical parking device, a vehicle having a size that is not so different from the length from the end on the entrance / exit entrance side to the end on the counter entry / exit entrance side of the entire range that can be entered is received. There are things to do.

  When trying to store such a vehicle in accordance with the instruction of the stop position indicating lamp shown in Patent Document 1, the following problems arise.

  That is, when a vehicle that has entered the loading / unloading section from the loading / unloading port proceeds on the pallet, first, a “forward” instruction is given by the stop position indicator lamp. Therefore, the user advances the vehicle in accordance with the “forward” instruction of the stop position indicator light. When the user continues to advance the vehicle, when the rear end side of the vehicle passes the end of the warehousing range on the entrance / exit side, the “stop” instruction is once given by the stop position indicator lamp. However, as soon as the vehicle is moving forward from the time when the “stop” instruction is given by the stop position indicator light, the front end of the vehicle will immediately protrude from the end of the entry / exit entrance side of the entry range. Therefore, the instruction with the stop position indicator lamp is switched to “reverse”.

  After that, when the user moves the vehicle backward according to the “reverse” instruction by the stop position indicator light, the stop position indicator light is passed when the front end side of the vehicle passes the end of the entry / exit side of the entry range. In the case of “stop” once, if the vehicle continues to reverse from that point on, the rear end of the vehicle will immediately protrude from the end of the entry / exit side of the entry range. The instruction with the indicator light is switched to “forward”.

  As described above, in the stop position indicating lamp shown in Patent Document 1, it is possible to instruct the user to “forward” or “reverse” as the moving direction for placing the vehicle in the garageable range. However, no information about the distance traveled forward or backward is displayed. Therefore, the actual situation is that the user does not know the distance that the vehicle can move forward or the distance to move backward when the vehicle is placed in the warehousing range.

  Therefore, when entering a vehicle having a total length that is not so different from the length from the end of the warehousing range on the entrance / exit entrance side to the end on the anti-entry / exit entrance side, the vehicle is stopped in the entry range. By the time, there is a possibility that the forward and backward movements according to the instruction of the stop position indicator lamp as described above are repeated many times. Therefore, in this case, it takes time to store the vehicle.

  Accordingly, the present invention provides a mechanical parking system that can clearly indicate the distance that the vehicle can move forward and the distance that the vehicle should move backward, together with information related to vehicle position correction that is required to place the vehicle in the allowable range when the vehicle is stored. The device is to be provided.

  In order to solve the above-mentioned problem, the present invention detects the presence or absence of a vehicle at the position of the warehousing part, the warehousing port communicating with the warehousing part, and the entrance side end of the garageable range set in the warehousing part. The first sensor, the second sensor for detecting the presence or absence of a vehicle at the position of the opposite entrance side end of the warehousing possible range, and the back side opposite to the warehousing port side in the warehousing part are provided. A distance measuring means for measuring the distance to the front end of the vehicle to be stored, a display device provided on the back side in the storage unit, and a display controller, wherein the display controller includes the first controller Based on the detection result of the second sensor, the detection result of the second sensor, and the measurement result of the distance measuring means, the display unit relates to position correction for storing the vehicle to be stored in the storage range. Along with the information, The mechanical parking device from the opposite inlet end having a configuration including the function of providing an instruction to display the distance information about the distance to the front end of the vehicle for the goods receipt.

  The display controller has a function of causing the display to display the distance information as information on a distance that the vehicle can move forward and information on a distance that the vehicle should move backward.

  The display controller has a function of causing the display to display the distance information in units of a set distance.

  ADVANTAGE OF THE INVENTION According to this invention, the distance which can be advanced and the distance which should reverse | retreat can be specified with the moving direction for accommodating a vehicle in the warehousing possible range at the time of warehousing of a vehicle.

  Of course, the display device 6 may be arranged in a manner other than that shown in the drawing as long as the user who drives the vehicle 5 traveling on the pallet 4 can visually recognize the displayed content.

  As will be described later, the display 6 displays information 20a, 20b, 21, 22a, and 22b (see FIGS. 5A, 5B, and 5C) in accordance with a command received from the display controller 8 (see FIG. 4). It has a function.

  Next, the function of the display controller 8 will be described. In addition, in the following, information 20a, 20b, 21, 22a, and 22b displayed on the display 6 will be described together with description of the function of the display controller 8.

  As shown in FIG. 4, the display controller 8 has a function of receiving a signal a that the warehousing operation has been performed from the operation panel 19 when the warehousing operation is performed on the operation panel 19, and the first sensor 14. The function of receiving the detection result of the presence or absence of the vehicle 5 at the entrance side end 9b of the warehousing range 9 and the detection result of the presence or absence of the vehicle 5 at the counter entrance side end 9a of the warehousing range 9 from the second sensor 15 And a function of receiving a measurement result of a distance from the laser rangefinder 7 to the front end of the vehicle 5.

  When the display controller 8 receives the measurement result of the distance from the laser rangefinder 7 to the front end of the vehicle 5, based on the measurement result, the display controller 8 and the counter entrance side of the warehousing range 9. A function of calculating the distance to the end 9a is provided.

  In the mechanical parking device of the present embodiment, the position where the laser distance meter 7 is installed and the position where the counter entrance side end 9a of the warehousing range 9 is set are determined. The distance from the installation position of the laser rangefinder 7 to the end 9a opposite to the entrance 9 in the warehousing range 9 is known. The display controller 8 stores this distance b in advance.

  When the display controller 8 receives the measurement result of the distance from the laser distance meter 7 to the front end portion of the vehicle 5, the measurement result is taken as c, and the difference d between the distance b and the measurement result c is, for example, c−b. = D is provided. As a result, the difference d indicates the distance to the front end of the vehicle 5 with the absolute value as the reference (zero) based on the position of the counter entrance side end 9a of the warehousing range 9. Further, the sign of the value of the difference d indicates the relative arrangement of the front end portion of the vehicle 5 and the position of the counter entrance side end portion 9a of the warehousing range 9. In the case of the calculation formula, if the value of the difference d is positive, the front end portion of the vehicle 5 is present closer to the entrance / exit 3 than the position of the opposite entrance side end portion 9a of the entry range 9. This means that if the value of the difference d is negative, the front end of the vehicle 5 is opposite to the entrance / exit 3 with respect to the position of the opposite entrance end 9a of the entry range 9 (the entry / exit section). 2). When the value of the difference d is zero, it means that the front end portion of the vehicle 5 exists at the position of the opposite entrance side end portion 9 a of the warehousing range 9.

  When the display controller 8 receives the signal “a” indicating that the warehousing operation has been performed from the operation panel 19, the display controller 8 places the vehicle 5 in the garageable range 9 on the display 6 as shown in FIG. A command to display both the information 20a regarding the correction and the distance information 20b reflecting the absolute value of the difference d and clearly indicating the unit of the distance is given.

  At the time of starting warehousing, the moving direction of the vehicle 5 for placing the vehicle 5 in the warehousing range 9 is the forward direction, so the display controller 8 informs the display 6 as information 20a regarding position correction as the vehicle 5 A command is given to display information for instructing to advance, for example, “Please move forward”.

  At the same time, the display controller 8 reflects the absolute value of the difference d on the display 6 and uses the value X obtained by converting the absolute value of the difference d into a unit of “cm” as distance information 20b that clearly indicates the unit of distance. Is given a command to display information on the distance that the vehicle 5 can move forward, for example, “You can move forward by Xcm”.

  In accordance with the command from the display controller 8 described above, the display 6 displays the information 20a and the distance information 20b related to position correction as shown in FIG.

  It should be noted that the unit of distance when displaying the distance information 20b and the distance information 22b described later is preferably set to use “cm” regardless of the unit of the measurement result output by the laser distance meter 7. . Further, at this time, it is preferable to display only integers by rounding down, rounding off, and rounding up after the decimal point. This is displayed when the position of the vehicle 5 is adjusted by moving the vehicle 5 forward and backward, and adjustment in units of “mm” is difficult, and the number of digits for displaying the numerical value is reduced as much as possible. This is to make it easier for the user to grasp the contents. However, the unit of distance is not limited to the setting using “cm”.

  After instructing the display 6 to display the information 20a, 20b as shown in FIG. 5A, the display controller 8 monitors the detection result received from the first sensor 14, and the first sensor 14 After the presence of the vehicle 5 is detected at the entrance side end 9b of the warehousing range 9, the display 6 shows in FIG. 5A until the presence of the vehicle 5 at the entrance side end 9b is no longer detected. The information 20a and 20b are continuously displayed.

  The state in which the presence of the vehicle 5 is detected by the first sensor 14 at the entrance side end 9b of the entry range 9 after starting the entry of the vehicle 5 with respect to the entry / exit unit 2 is as follows. It is in the state which has protruded to the entrance / exit 3 side from 9b. Further, after that, the presence of the vehicle 5 at the entrance side end portion 9b is not detected as the vehicle 5 moves forward and the rear end portion of the vehicle 5 passes through the entrance side end portion 9b of the warehousing range 9 It is. Therefore, in the mechanical parking device of the present embodiment, after the vehicle 5 is started to be stored in the storage / removal unit 2, the indicator 6 is displayed while the vehicle 5 is protruding from the entrance side end 9 b to the storage / exit 3 side. In addition, information 20a and 20b as shown in FIG. 5A is displayed. At this time, the value of X in the distance information 20b displayed on the display 6 gradually decreases as the vehicle 5 moves forward.

  After the vehicle 5 starts to be stored as described above, the second sensor 15 stores the vehicle 5 when the first sensor 14 no longer detects the presence of the vehicle 5 at the entrance side end 9b of the storage range 9. The state in which the presence of the vehicle 5 at the opposite end 9a of the possible range 9 is not detected means that the vehicle 5 is within the warehousing range 9. Therefore, in this case, the display controller 8 gives, for example, a command for displaying “reception completed” to the display 6 as information 21 instructing to stop the vehicle 5 as shown in FIG. Has the function to give.

  In accordance with the command from the display controller 8, the display 6 displays information 21 instructing to stop the vehicle, as shown in FIG. In addition, as long as it can instruct | stop the vehicle 5 with respect to the user who drives the vehicle 5, as the information 21 which instruct | indicates the stop of the vehicle displayed on the indicator 6, it is good also as a display of "stop", for example. .

  In the state where the first sensor 14 detects the presence of the vehicle 5 at the entrance-side end 9b of the warehousing range 9, the second sensor 15 detects the presence of the vehicle 5 at the counter-entrance-side end 9a. If the presence of the vehicle 5 is also detected, this means that the entire length of the vehicle 5 does not fit in the garageable range 9, that is, cannot be stored in the mechanical parking device of this embodiment. The vehicle 5 may be instructed to leave the loading / unloading unit 2 by using information transmitting means such as voice provided separately in the mechanical parking apparatus of the present embodiment.

  Furthermore, after the first sensor 14 once detects the presence of the vehicle 5 at the inlet side end portion 9b and the vehicle 5 falls within the warehousing range 9, the first sensor 14 enters the inlet side. When the presence of the vehicle 5 at the end 9b is detected again, the display controller 8 instructs the display 6 to display the information 20a, 20b again as shown in FIG. Has the function to give.

  On the other hand, as described above, the presence of the vehicle 5 at the entrance-side end 9b is no longer detected by the first sensor 14 and can be stored by the second sensor 15 after the vehicle 5 falls within the storage range 9. When the presence of the vehicle 5 at the opposite end 9a of the range 9 is detected, the display controller 8 displays on the display 6 information indicating the backward movement of the vehicle 5 as the position correction information 22a. For example, a command to display “Please retreat” is given. At the same time, the display controller 8 reflects the absolute value of the difference d on the display 6 as the distance information 22b that clearly indicates the unit of distance, and a value X obtained by converting the absolute value of the difference d into a unit of “cm”. Is provided with a function of giving a command for displaying information on the distance to which the vehicle 5 should retreat, for example, “It is necessary to retreat further Xcm”.

  In accordance with the command from the display controller 8, the display 6 displays information 22a and distance information 22b related to position correction, as shown in FIG. The value of X in the distance information 22b displayed on the display 6 gradually decreases as the vehicle 5 moves backward.

  In the mechanical parking device according to the present embodiment, the display controller 8 determines the detection results of the sensors 14 and 15 and the laser distance meter as described above with respect to the warehousing process started in response to the warehousing operation on the operation panel 19. 7 is provided with a function of performing a warehousing process similar to that of an existing mechanical parking device, except that the display 6 is instructed and displayed based on the measurement result 7.

Therefore, the display 6 has a position for instructing the vehicle 5 to move forward as shown in FIG. Information about correction 20a and distance information 20b in which the distance that the vehicle 5 can move forward are displayed together with the unit of distance.

  A user who drives the vehicle 5 and enters the loading / unloading unit 2 through the loading / unloading port 3 visually recognizes the information 20a and 20b displayed on the display 6 arranged on the front, thereby moving the vehicle 5 to the current position. From this, it can be seen that the vehicle 5 should be advanced, and the distance that the vehicle 5 can be advanced is also known. Therefore, the user may advance the vehicle 5 according to the information 20a, 20b displayed on the display device 6.

  As the vehicle 5 moves forward, the distance information 20b of the information 20a, 20b displayed on the display 6 gradually decreases the numerical value of the distance that the vehicle 5 can move forward. It is possible to easily grasp that the vehicle needs to move forward from the position and the remaining distance that the vehicle 5 can move forward. Therefore, the user can easily carry out the adjustment of slowing down the forward speed of the vehicle 5 as the remaining distance in which the vehicle 5 can move forward decreases.

  After that, when the vehicle 5 moves forward and falls within the warehousing range 9, the vehicle 5 is not detected by the first sensor 14, so the display 6 displays the information 20 a and 20 b shown in FIG. It disappears and it switches to the display of the information 21 which instruct | indicates the stop of the vehicle shown in FIG.5 (b). Thereby, it is understood that the user only has to finish the advance of the vehicle 5 and stop the vehicle 5 on the spot. Therefore, if the user stops the vehicle 5 while the display of FIG. 5B is performed, the vehicle 5 is stopped in a state where it falls within the warehousing range.

  Therefore, in this state, the user can apply the parking brake to the vehicle 5 and get off from the vehicle 5.

  As described above, when the user does not stop the advance of the vehicle 5 promptly when the information 21 instructing the stop of the vehicle shown in FIG. The front end side may protrude from the counter entrance side end portion 9a of the warehousing range 9. In such a situation, since the vehicle 5 is detected by the second sensor 15, information 22 a regarding position correction for instructing the vehicle 5 to move backward is displayed on the display 6. The distance information 22b in which the distance to be retreated is specified together with the unit of distance is displayed.

  Thereby, the user can recognize that the vehicle 5 should be moved backward from the current position by visually recognizing the information 22a and 22b displayed on the display 6, and the distance to which the vehicle 5 should be moved back is also determined. I understand. Therefore, the user may retreat the vehicle 5 in accordance with the information 20a and 20b displayed on the display device 6, paying particular attention to the distance information 22b indicating the distance to which the vehicle 5 should retreat.

  As the vehicle 5 moves backward, the distance information 22b of the information 22a and 22b displayed on the display 6 gradually decreases the numerical value of the distance to which the vehicle 5 should be moved backward. It is possible to easily grasp how many centimeters the vehicle should reverse, and it is possible to easily adjust the vehicle 5 to move backward as the remaining distance to reverse decreases.

  When the vehicle 5 falls within the garageable range 9 due to the backward movement of the vehicle 5, the vehicle 5 is not detected by the second sensor 15, so the display 6 displays information 22 a and 22 b shown in FIG. Disappears, and the display is switched to the display of the information 21 instructing the stop of the vehicle shown in FIG. Thereby, it is understood that the user only needs to end the backward movement of the vehicle 5 and stop the vehicle 5 on the spot. Therefore, if the user stops the vehicle 5 while the display of FIG. 5B is performed, the vehicle 5 is stopped in a state where it falls within the warehousing range.

  Therefore, in this state, the user can get off the vehicle 5 by applying the parking brake to the vehicle 5 as described above.

  In addition, when the vehicle 5 retreats too much and protrudes from the entrance side end portion 9b of the warehousing range 9, the information 6a and 20b shown in FIG. Therefore, the user may move the vehicle 5 forward while keeping the speed in a state where the remaining distance that can be advanced based on the distance information 20b is grasped, so that the vehicle 5 can be stored in the warehousing range 9.

  As described above, according to the mechanical parking device of the present embodiment, when the vehicle 5 is stored, the display 6 can move forward when information 20a related to position correction instructing the vehicle 5 to move forward is displayed. The distance information 20b regarding the distance can be specified together, and when the information 22a regarding the position correction instructing the backward movement of the vehicle 5 is displayed, the distance information 22b regarding the distance to be reversed can be displayed together.

  Therefore, for example, even when the vehicle 5 enters the vehicle 5 having a length that is not so different from the length dimension from the opposite entrance side end 9a to the entrance side end 9b of the entry range 9 as the vehicle 5. According to the present embodiment, as described above, the display 6 indicates the distance that the vehicle can move forward when moving forward, and in the unlikely event that the vehicle 5 moves backward, the vehicle 5 moves backward in order to place the vehicle 5 in the warehousing range 9. Easily know the distance to be. Therefore, if the user adjusts to decrease the forward speed and the reverse speed as the distances decrease, the user can display the display 6 on the display 6 as shown in FIG. It becomes easy to stop the vehicle 5 in a state where the information 21 instructing the stop of the vehicle is displayed. For this reason, when warehousing the vehicle 5, it is possible to expect an effect of shortening the time for the vehicle 5 to be within the warehousing range 9 and an effect of improving the ease of warehousing.

[Second Embodiment]
FIG. 6 shows a second embodiment of the mechanical parking apparatus, and is a schematic cut side view of the loading / unloading section. FIG. 7 is a diagram showing a display example of the display.

  6 and 7, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  In the mechanical parking device of the present embodiment, in the same configuration as in the first embodiment, the display controller 8 displays based on the detection results of the sensors 14 and 15 and the measurement result c by the laser distance meter 7. In addition to the function of giving a command to display the information 20a, 20b, information 21, and information 22a, 22b shown in FIGS. 5 (a), 5 (b), and 5 (c), the display controller 8 A command to display information 23 for guiding the vehicle 5 to the center of the warehousing range 9 on the display unit 6 as shown in FIG. The function of further providing the function is provided.

  Here, derivation of functions additionally provided in the display controller 8 in the present embodiment will be described.

  In the mechanical parking device according to the first embodiment, after the vehicle 5 starts to be stored, the first sensor 14 does not detect the presence of the vehicle 5 at the entrance side end portion 9b of the storage possible range 9, and the second When the detection of the presence of the vehicle 5 at the counter entrance side end portion 9a by the sensor 15 is not performed, the vehicle 5 that starts moving in and moves forward is first placed in the warehousing range 9. Therefore, the display controller 8 instructs the display 6 to stop the vehicle 5 as shown in FIG. 5B instead of the information 20a and the distance information 20b shown in FIG. A command to display is displayed.

  Therefore, immediately after the information 21 is displayed on the display 6, if the user stops the vehicle 5 moving forward according to the displayed information 21, the vehicle 5 The end portion is placed in the warehousing range 9 in an arrangement close to the inlet side end portion 9b.

  Thus, in a state where the vehicle 5 is in the warehousing range 9, the position of the rear end portion of the vehicle 5 is close to the entrance-side end portion 9 b of the warehousing range 9. Is not affected. Therefore, in the state where the vehicle 5 is accommodated in the warehousing range 9 as described above, the total length of the vehicle 5 is the length dimension from the opposite entrance side end portion 9a to the entrance side end portion 9b (hereinafter, The margin from the front end of the vehicle 5 to the end opposite to the entrance side of the warehousing range 9 becomes smaller as it is closer to the front and rear length of the warehousing range 9, while the front end of the vehicle 5 becomes shorter as the total length of the vehicle 5 is shorter The remainder from the part to the end of the warehousing range 9 on the side opposite to the entrance becomes large.

  Therefore, as for the pallet 4 on which the vehicle 5 within the warehousing range 9 is placed, the weight balance of the vehicle 5 in the longitudinal direction of the pallet 4 becomes smaller as the total length of the vehicle 5 is closer to the front and rear length of the warehousing range 9. On the other hand, the shorter the overall length of the vehicle 5, the greater the tendency that the balance of the weight of the vehicle 5 in the longitudinal direction of the pallet 4 becomes more uneven.

  By the way, depending on the type of the cage 16 and each suspension rope 17 as a transporter that transports the vehicle 5, it is desirable that the load applied to each suspension rope 17 is not as uneven as possible when the vehicle 5 is transported. May be.

  In addition, many turntables (not shown) provided in the loading / unloading unit 2 and the cage 16 are swiveled in a state where the center portions except for both ends in the longitudinal direction of the pallet 4 are supported. Therefore, depending on the type of the turntable, it is desirable that the weight of the vehicle 5 is not biased toward one end in the longitudinal direction of the pallet 4 when the pallet 4 on which the vehicle 5 is placed is turned. There is a case.

  Therefore, as a countermeasure for such a case, the mechanical parking device according to the present embodiment, when the vehicle 5 to be stored is a vehicle 5 whose overall length is shorter than the set reference, the vehicle 5 is stored in the storage range 9. It is possible to guide the vehicle to the center of the warehousing range 9 and stop it immediately after it is received.

  Therefore, the display controller 8 has the following functions.

  Similar to the first embodiment, the display controller 8 has a function of obtaining the difference d when the vehicle 5 enters the vehicle. Further, the display controller 8 further includes a range 9 in which the vehicle 5 entering the entry / exit unit 2 through the entry / exit port 3 can enter. At the time when the vehicle 5 is first detected by the first sensor 14, that is, when the presence of the vehicle 5 is no longer detected at the entrance-side end 9 b of the warehousing range 9, the value of the difference d obtained at that time is A function of temporarily storing as a surplus distance d1 from the front end portion to the counter entrance side end portion 9a of the warehousing range 9.

  This excess distance d1 represents the difference between the front and rear length of the warehousing range 9 and the total length of the vehicle 5 that has entered the warehouse.

  Accordingly, whether or not the total length of the vehicle 5 that has been received is shorter than the set reference is determined by comparing the value of the reference with the value calculated by subtracting the reference value from the length before and after the storage range 9. It is possible to determine whether or not the distance d1 is large.

  In view of this point, the display controller 8 has a function of storing a reference value D set for comparison with the remainder distance d1. The reference value D is set as an arbitrary constant such as 100 cm, 120 cm, and 150 cm. Note that the value of the reference value D is an example, and it is needless to say that the reference value D may be freely changed according to the front and rear length of the warehousing range 9.

  The display controller 8 has a function of instructing the display 6 to display information 20a and 20b as shown in FIG. 5A when the vehicle 5 is received. This is the same as in the first embodiment.

  After that, the display controller 8 stops detecting the presence of the vehicle 5 at the entrance side end portion 9b of the warehousing range 9 by the first sensor 14, and the second sensor 15 detects the non-entrance side end of the warehousing range 9 When the detection of the presence of the vehicle 5 in the part 9a is not performed, the remaining distance d1 obtained at that time is compared with the reference value D.

  As a result, when the remaining distance d1 is within the reference value D (when d1 ≦ D), the display controller 8 instructs the display 6 to stop the vehicle 5 as shown in FIG. The function of giving a command for displaying the information 21 to be displayed is provided. The point which gives the command which displays this information 21 to indicator 6 is the same as that of a 1st embodiment.

  On the other hand, as a result of the comparison, when the remaining distance d1 is larger than the reference value D (when d1> D), the display controller 8 determines the difference between the distance b and the measurement result c of the laser rangefinder 7. A value Y obtained by subtracting a half value of the remainder distance d1 from the absolute value of d and converting the result into a unit of “cm” is obtained, and as shown in FIG. Based on the value Y, for example, a command is given to display that “you can stop in the center if you move forward Ycm later” as the information 23 that leads to the center of.

  In accordance with the command from the display controller 8, the display 6 displays information 23 as shown in FIG.

  The value of Y in the information 23 displayed on the display 6 gradually decreases as the vehicle 5 moves forward.

  Further, when the value of Y becomes zero as the vehicle 5 moves forward, the display controller 8 displays the information 21 for instructing the display device 6 to stop the vehicle 5 as shown in FIG. It has a function to give a command to display.

  In accordance with the command from the display controller 8, the display 6 displays information 21 instructing to stop the vehicle, as shown in FIG. Also in this case, if the user who drives the vehicle 5 can be instructed to stop the vehicle 5, the information 21 to instruct the stop of the vehicle displayed on the display 6 is, for example, a display of “stop”. There may be.

  Note that the information 23 is displayed on the display 6 only when the difference between the total length of the vehicle 5 and the front and rear length of the warehousing range 9 is large to some extent. It is not limited to the position where the value of Y is zero, and it is only necessary to approach the position where the value of Y is zero. Therefore, for example, when the value of Y decreases to about 5 cm or 10 cm as the vehicle 5 moves forward, the display controller 8 displays the information 21 shown in FIG. A command for performing display may be given. If it does in this way, the user who drives the vehicle 5 will perform the operation which stops the vehicle 5 after seeing the display of the information 21 of FIG. 9 can be stopped at approximately the center.

  In the display controller 8, the function when the presence of the vehicle 5 is detected at the opposite entrance end 9 a of the warehousing range 9 by the second sensor 15 is the same as in the first embodiment.

  According to the mechanical parking device of the present embodiment having the above configuration, the vehicle 5 having a shorter overall length than the set reference can be obtained in the same manner as in the first embodiment and the same effect can be obtained. Can be guided and stopped from the state within the warehousing range 9 to the center of the warehousing range 9.

  For this reason, the mechanical parking apparatus of this embodiment can suppress the load applied to each suspension line 17 of the cage 16 from becoming uneven when the vehicle 5 is transported by the cage 16 that is a transporter.

  The mechanical parking device of the present embodiment is configured such that when the pallet 4 on which the vehicle 5 is placed is turned by a turntable provided in the loading / unloading unit 2 or the cage 16, the weight of the vehicle 5 is in the longitudinal direction of the pallet 4. The bias toward one end side can be suppressed.

  In addition, this invention is not limited only to above-described embodiment, If it is a mechanical parking apparatus of the type provided with the entering / exiting part 2 which carries in the vehicle 5 at the time of the receipt of the vehicle 5, for example, a vertical circulation A mechanical parking device other than the illustrated elevator system, such as a system, a plane reciprocation system, a horizontal circulation system, and a multi-layer circulation system, and transportation of the vehicle 5 between the storage / exit section 2 and the storage area without using the pallet 4 The present invention can be similarly applied to a mechanical parking apparatus of a type directly performed by a transporter.

  In each embodiment, although the mechanical parking apparatus of the form which performs the warehousing and warehousing of a vehicle in a common warehousing and unloading part was illustrated, the warehousing part which has the warehousing port which performs warehousing of vehicles, and the warehousing opening which performs the warehousing of vehicles May be applied to a mechanical parking device of a type separately provided with a delivery unit having a display, and in this case, the display 6, the laser distance meter 7, the display controller 8, the first sensor 14, and the second sensor What is necessary is just to equip 15 to the warehousing part side.

  In each embodiment, the laser distance meter 7 is exemplified as the distance measuring means, but a distance meter other than the laser distance meter may be used as long as it can measure the distance to the front end portion of the entering vehicle 5. .

  If the information 20a regarding the position correction displayed on the display device 6 is a display instructing the vehicle 5 to move forward, the wording may be changed as appropriate. If the distance information 20b is a display of information on the distance that the vehicle 5 can move forward, the wording may be changed as appropriate. If the information 21 can instruct the stop of the vehicle 5, the wording may be changed as appropriate. If the information 22a regarding the position correction is a display instructing the vehicle 5 to move backward, the wording may be appropriately changed. If the distance information 22b is a display of information on the distance to which the vehicle 5 should retreat, the wording may be changed as appropriate. If the information 23 is a display that guides the vehicle 5 to the center of the warehousing range 9, the wording may be changed as appropriate.

  In addition, it goes without saying that various modifications can be made without departing from the scope of the present invention.
