Description

  The present invention relates to a parking apparatus that transports a vehicle to a storage shelf by a lift cage.

  Conventionally, when an incoming vehicle stops at a regular position on the entry / exit floor of a mechanical parking device, the detection of the protrusion of the vehicle is performed by the detector installed in the parking device, and when the protrusion is detected, Thereafter, control that does not start the machine is performed.

  However, since the detectors do not detect protrusions during machine operation after warehousing, for example, when the rear door (hatchback door) of the vehicle is not completely closed or half-opened, Even if the rear door is opened due to shock or vibration when the is operating, it cannot be detected.

  Therefore, what detects the flip-up of the rear door at the time of machine operation after warehousing has been proposed. The lift cage includes a detector that detects whether or not the height of a vehicle parked by projecting and receiving light in the front-rear direction is within an upper limit value (see, for example, Patent Document 1). ).

  Patent Document 1 describes a detector for a high roof car and a detection for a normal car on brackets extending in the vertical direction attached to the front end side and the rear end side of a lift cage that is lifted and lowered by an underground multilevel parking device. Are provided at positions slightly higher than the upper limit of the height of the high roof vehicle and the normal vehicle, respectively. As a result, even if the rear door of the high roof car or the normal car is opened or there is an input error between the normal car and the high roof car at the time of warehousing, an accident can be prevented.

  In recent years, a mechanical parking apparatus having a building on the ground includes a storage shelf for a normal vehicle that stores a normal vehicle with a low vehicle height, and a storage shelf for a high roof vehicle that stores a high roof vehicle with a high vehicle height. Many of the configurations have different hierarchies. Many of such parking devices are provided with a storage shelf for ordinary vehicles at the top.

Japanese Patent Laid-Open No. 10-046856

  However, the device described in Patent Document 1 is provided with a detector for a high roof vehicle and a detector for a normal vehicle on the upper end side of a bracket attached to the lift cage. There is a detector for high roof cars at a higher position.

  Therefore, although what is described in Patent Document 1 can be applied to a multilevel parking device in the basement without problems, a storage rack for ordinary cars and a storage rack for high roof cars are provided in multiple stages in the building. It is difficult to apply to a parking device in which the uppermost storage shelf is a storage shelf for ordinary vehicles. This is because if the lift cage is raised to the level of the storage rack for the uppermost ordinary car, the detector for the high roof car may interfere with the uppermost ceiling.

  Therefore, the present invention comprises a plurality of vehicle height division storage shelves as storage shelves for storing vehicles, and the uppermost storage shelf is a vehicle other than the highest vehicle height division among the plurality of vehicle height divisions. An object of the present invention is to provide a parking device that can detect the protrusion of a vehicle due to the rear door bounce-up of a vehicle placed on a lift cage in a parking device that is a storage shelf of a vehicle height section.

  In order to solve the above-mentioned problem, the present invention includes a plurality of storage shelves of a plurality of vehicle height categories as storage shelves for storing vehicles, and the highest storage shelf is the highest of the plurality of vehicle height categories. In a parking device that is a storage shelf for a vehicle height section other than a vehicle height section, a lift cage that moves up and down a lift hoistway, a detector support bracket that stands on four corners of the lift cage, the detector support bracket, and the lift cage And a telescopic mechanism for vertically displacing the detector support bracket with respect to the lift cage, and a height of a vehicle mounted on the lift cage and mounted on the upper end side of each detector support bracket. And a detector that detects a protrusion in the vertical direction, and the telescopic mechanism is a parking device having a configuration that contracts when the lift cage is at the position of the uppermost storage shelf. .

  The telescopic mechanism is a telescopic actuator attached to the lift cage, and is configured such that the upper end side of the actuator is connected to the lower end of the detector support bracket.

  The expansion / contraction mechanism is a spring extending and contracting in the vertical direction interposed between the lift cage and the detector support bracket, and the detector is a restriction on the plurality of vehicle height sections in the detector support bracket. It is set as the structure which is a some detector attached to the height position.

  When the lift cage is at the position of the uppermost storage shelf, the spring contracts, and among the plurality of detectors attached to the detector support bracket, it is at the limit height position of the highest vehicle height section. The attached detector is arranged at a restricted height position in the vehicle height section of the uppermost storage shelf.

  When the lift cage is at the position of the uppermost storage shelf, the height of the vehicle on which the detector placed at the restricted height position of the vehicle height section of the uppermost storage shelf is placed on the lift cage It is configured to function as a detector that detects the protrusion of the direction.

  According to the present invention, storage shelves of a plurality of vehicle height sections are provided in multiple stages as storage shelves for storing vehicles, and a car other than the highest vehicle height section among the plurality of vehicle height sections is provided in the uppermost storage shelf. In the parking device, which is a high-level storage shelf, it is possible to detect the protrusion of the vehicle due to the rear door jumping up on the lift cage.

  Hereinafter, the parking apparatus of the present invention will be described with reference to the drawings.

[First Embodiment]
1 to 7 show an outline of the first embodiment of the parking apparatus.

  1 is a partially cut schematic side view of a lift cage in the parking apparatus of the present embodiment, FIG. 2 is a schematic plan view of FIG. 1, and FIG. 3 is a schematic view taken along line AA of FIG. 4 (a) and 4 (b) are schematic side views showing a state in which the actuator, which is the expansion / contraction mechanism in the present embodiment, is extended upward, and FIGS. 5 (a) and 5 (b) are views in which the actuator in the present embodiment is shortened. It is a schematic side view which shows the state which exists. FIG. 6 is a control block diagram. FIG. 7 is a schematic view showing the overall configuration of the parking apparatus of the present embodiment.

  As shown in FIG. 7, an elevator type parking apparatus, which is one of mechanical parking apparatuses, has a central portion of the building 1 as a lift hoistway 3 in which a lift cage 2 moves up and down. On both sides of the lift hoistway 3, for example, storage shelves 4a for ordinary vehicles 4 and storage shelves 5a for high-roof vehicles 5 are provided in multiple stages as storage shelves for a plurality of vehicle height sections, and if necessary, A storage shelf 6a for a middle roof vehicle 6 having an intermediate vehicle height between the ordinary vehicle 4 and the high roof vehicle 5 is also provided. In the uppermost row, for example, a storage shelf 4a for a normal vehicle 4 is provided as a storage shelf for a vehicle height category other than the highest vehicle height category among the plurality of vehicle height categories.

  Note that the vehicle height category is a category for limiting the vehicle height of a vehicle that can be stored, which is set in the parking device. For example, the vehicle height category referred to as a normal vehicle is up to a vehicle height of X mm (for example, 1550 mm), a high roof. The vehicle height classification referred to as a vehicle is a value set to a vehicle height Ymm (for example, 2050 mm), the vehicle height classification referred to as a middle roof vehicle is a value set to a vehicle height Zmm (for example, 1800 mm) that is intermediate between them. is there. Of course, the names given to each vehicle height category such as ordinary vehicles and high roof vehicles are not limited to these. Of course, the number of vehicle height categories may be changed as appropriate according to the height of the storage shelf provided in the parking device and the way the parking device is operated.

  A driving device 7 for raising and lowering the lift cage 2 is installed on the upper portion of the building 1. Four suspension members 8 such as chains or wires are fed out from the drive device 7, and each suspension member 8 is attached to the top of a vertical frame 13 (described later) at the four corners of the lift cage 2. Thereby, the lift cage 2 moves up and down the lift hoistway 3 through the suspension member 8 by driving of the driving device 7.

  The lift cage 2 provided in the parking apparatus of the present embodiment includes a cage frame 10 having a rectangular planar shape and a vertical frame 13 as shown in FIGS. 1 to 3, for example. The cage frame 10 has a configuration in which two beam members 11 extending horizontally and two beam members 12 extending in the horizontal direction perpendicular thereto are assembled in a rectangular shape. The vertical frame 13 is attached to the four corners of the cage frame 10 so as to project outward, and has a configuration extending in the vertical direction. A pallet 9 is placed on the cage frame 10 via a support member 10a. At the top of each vertical frame 13, as described above, the tip of the suspension member 8 drawn out from the driving device 7 of FIG. 7 is attached.

  As shown in FIGS. 1 and 2, a turning device (turn table) 14 for turning the loading / unloading vehicle 90 degrees or 180 degrees is mounted on the central portion of the cage frame 10. The swivel device 14 includes a support frame 15 attached below the central portion of the cage frame 10. On the support frame 15, a swivel base 16 is supported so as to be lifted and lowered via a lifting device 17. A swivel ring 18 is provided above the swivel base 16, and a swivel frame 19 is provided integrally with the swivel ring 18 above the swivel ring 18. A gear 21 attached to the output shaft of the speed reducer 20 is meshed with the ring gear on the outer peripheral surface of the swivel ring 18. A drive device 22 is connected to the speed reducer 20. Accordingly, the turning frame 19 is turned by rotating the turning ring 18 by the driving device 22.

  An actuator 29 as an expansion / contraction mechanism is attached upward to the two vertical frames 13 on one end side in the longitudinal direction of the cage frame 10 (left side in FIGS. 1 and 2). A base end (lower end) side of an elongated detector support bracket 28 extending in the vertical direction is connected to the upper end side of the actuator 29. At the front end (upper end) of the detector support bracket 28, for example, a projector 25 that projects a beam of light 27 is attached. For the detector support bracket 28, it is preferable to use an angle material in order to reduce weight and prevent bending.

  An actuator 29 as an expansion / contraction mechanism is attached upward to the two vertical frames 13 on the other longitudinal end side (the right side in FIGS. 1 and 2) of the cage frame 10. A base end (lower end) side of an elongated detector support bracket 28 extending in the vertical direction is connected to the upper end side of the actuator 29. At the front end (upper end) of the detector support bracket 28, a light receiver 26 that receives the beam-like light 27 projected from the light projector 25 is attached. In this case as well, it is preferable to use an angle material for the detector support bracket 28 in order to reduce the weight and prevent bending.

  The light projector 25 and the light receiver 26 constitute a detector 24 as a pair, and are arranged at diagonal positions with respect to the lift cage 2 as shown in FIG. Thereby, the light 27 projected from each projector 25 is received by each light receiver 26 at a diagonal position intersecting on the lift cage 2. With this arrangement, even if the projector 25 and the light receiver 26 are arranged outside the lift cage 2, the detector 24 causes the rear door 31 of the vehicle to spring up based on the fact that the light 27 is blocked. A state of protruding upward is detected.

  The actuator 29 shown in FIGS. 4A, 4B, and 5A, 5B is an electric actuator using an AC servo motor and is of a type that moves and extends and contracts the rod 30. FIG. However, this is only an example, and the present invention is not limited to this type, and it is needless to say that any other type may be used as long as the rod is extended and contracted. If the detector support bracket 28 can be moved up and down with respect to the vertical frame 13 of the lift cage 2, an electric jack, a ball screw type linear motion mechanism, a rack and pinion type linear motion mechanism, etc. A configuration in which such a lifting mechanism is interposed between the vertical frame 13 and the detector support bracket 28 may be adopted.

  Each detector 24 (projector 25 and light receiver 26) extends the actuator 29 as shown in FIG. 4 so that the vehicle height classification set in the storage shelf 5a (see FIG. 7) on the lift cage 2 is increased. It is installed at the restricted height position. This limit height position of the vehicle height section is used to determine whether or not the height of the vehicle mounted on the lift cage 2 conforms to the above-described limit of Ymm which is the vehicle height section of the high roof car. In this embodiment, the height from the surface of the pallet 9 that is the mounting surface of the vehicle on the lift cage 2 is a position slightly higher than Ymm. Hereinafter, this height position is referred to as a first protrusion detection position H1.

  On the other hand, by shortening the actuator 29 as shown in FIGS. 5 (a) and 5 (b), the detector 24 is provided on the lift cage 2 in the vehicle height section set in the storage shelf 4a (see FIG. 7). Installed at the restricted height position. In this case, the limit height position of the vehicle height section is determined whether or not the height of the vehicle mounted on the lift cage 2 conforms to the above-described limit of Xmm which is the vehicle height section of the ordinary vehicle. The height from the surface of the pallet 9 on the lift cage 2 is a position slightly higher than X mm. Hereinafter, this height position is referred to as a second protrusion detection position H2.

  Although not shown, the actuator 29 expands and contracts to an intermediate stroke between the expanded state as shown in FIGS. 4 (a) and 4 (b) and the contracted state as shown in FIGS. 5 (a) and 5 (b). When this is done, the detector 24 is installed on the lift cage 2 at the restricted height position of the vehicle height section set in the storage shelf 6a (see FIG. 7). The limit height position of the vehicle height section in this case is whether or not the height of the vehicle mounted on the lift cage 2 conforms to the above-described limit of Zmm which is the vehicle height section of the middle roof car. It is a position for determination, and the height from the surface of the pallet 9 on the lift cage 2 is a position slightly higher than Zmm. Hereinafter, this height position is referred to as a third protrusion detection position.

  As described above, when the pallet 9 corresponding to the vehicle to be stored is called from the storage shelves 4a, 5a, and 6a for storing the vehicle, the actuator 29 detects the first protrusion detection position corresponding to the storage shelves 4a, 5a, and 6a. The stroke is controlled so that the detector 24 is installed at the H1 or second protrusion detection position H2 or the third protrusion detection position.

  FIG. 6 is a control block diagram for controlling the actuator 29. In the figure, reference numeral 32 denotes a first control device that sends a command to the actuator 29. The first control device 32 includes, for example, a pallet 9 mounted on the lift cage 2 in order to carry in / out a vehicle from a control panel (operation panel) 33 that manages the entry / exit operation of the parking device. , 5a, 6a, information a indicating whether the palette 9 is called is input.

  If the first control device 32 determines that the pallet 9 mounted on the lift cage 2 is called from the storage shelf 4a based on the information a from the control panel 33, the first control device 32 detects it on the actuator 29. A control command b for installing the device 24 (the projector 25 and the light receiver 26) at the second protrusion detection position H2 shown in FIGS.

  If the first control device 32 determines that the pallet 9 mounted on the lift cage 2 is called from the storage shelf 5 a based on the information a from the control panel 33, the first control device 32 sends the information to the actuator 29. The control command b for giving the detector 24 to the first protrusion detection position H1 shown in FIGS. 4 (a) and 4 (b) is given.

  Similarly, if the first control device 32 determines that the pallet 9 mounted on the lift cage 2 is called from the storage shelf 6a based on the information a from the control panel 33, the actuator 29 The control command b for installing the detector 24 at the third protrusion detection position is given.

  As a result, the actuator 29 is controlled on the length of expansion / contraction stroke (expansion / contraction amount) based on the control command b from the first control device 32, and the pallet 9 in which the detector 24 is always mounted on the lift cage 2 is stored. The storage shelves 4a, 5a, 6a can be installed at a height position according to the restriction of the vehicle height section to which the storage shelves 4a, 5a, 6a belong.

  Therefore, in this embodiment, when a vehicle enters the pallet 9 mounted on the lift cage 2, the detector 24 restricts the vehicle height classification of the storage shelves 4a, 5a, 6a that are the storage destinations of the pallet 9. The first protrusion detection position H1 or the second protrusion detection position H2 or the third protrusion detection position according to the above is set. Therefore, when the rear door 31 of the vehicle is opened and jumped up and protrudes upward, the beam-like light 27 emitted from the light projector 25 and received by the light receiver 26 is blocked by the rear door 31. Based on this, the protrusion of the rear door 31 is detected.

  Further, as shown in FIGS. 1 and 7, each detector 24 includes a drive device 7 (see FIG. 7) that performs a mechanical operation at the time of loading and unloading in the parking device, and a mechanical operation that turns the vehicle on the lift cage 2. It is connected to the drive device 22 (see FIG. 1) of the turning device 14 that performs the above operation via the second control device 34. When the signal from the detector 24 is input and the light receiver 26 cannot receive the beam-like light 27 (the rear door 31 is opened, the light 27 is blocked). The signal from the detector 24 that is input at (5) is recognized as an overhang detection signal c. Further, the second control device 34 is configured to send a stop command d to the drive device 7 and the drive device 22 when the protrusion detection signal c from the detector 24 is input. When the drive device 7 and the drive device 22 receive the stop command d, the drive device 7 and the drive device 22 are controlled so as to stop the operation when the machine is in operation, and not to start a new machine operation thereafter.

  In FIG. 2, reference numeral 35 denotes a guide rail that guides the lifting and lowering of the lift cage 2 along the vertical frames 13 attached to the four corners of the lift cage 2, and along the lift hoistway 3 shown in FIG. Provided. 4 and 5, reference numeral 36 denotes a guide member that guides the vertical movement of the detector support bracket 28, and is provided so as to protrude to the outside of the vertical frame 13. In FIG. 7, reference numeral 37 denotes a pit. When the lift cage 2 is lowered to the entrance / exit 23 of FIG. 7, the lift cage 2 is stored in the pit 37 and is placed on the pallet 9 placed on the lift cage 2. A vehicle can be entered.

  Since the parking apparatus of the present embodiment has the above-described configuration, at the time of warehousing, the driver of the vehicle to be admitted inputs the contractor information and the like to the control panel 33, and stores the storage shelves 4a, Call the pallet 9 of 5a, 6a to the entrance / exit 23.

  With the start of the pallet calling process, the information a is input from the control panel 33 to the first control device 32. The first control device 32 gives a control command b to the actuator 29 based on the input information a. Thereby, in the lift cage 2, the expansion / contraction stroke of the actuator 29 is adjusted, and the detector 24 corresponds to the storage shelves 4a, 5a, 6a on which the pallet 9 moved onto the lift cage 2 is called out. The overhang detection position H1 or the second overhang detection position H2 or the third overhang detection position.

  If the vehicle to be stored is the normal vehicle 4, the detector 24 is disposed at the second protrusion detection position H2, and therefore when the normal vehicle 4 enters the pallet 9 on the lift cage 2, FIG. As shown in FIG. 3, the light beam 26 is received by the light receiver 26 from the light projector 25 above the ordinary vehicle 4 on the pallet 9.

  In this state, as shown in FIG. 1, when the rear door 31 of the ordinary vehicle 4 is opened and jumped upward and protrudes upward beyond the vehicle height section of the storage shelf 4a, the light 27 is opened. The light receiver 26 cannot receive the light 27 because it is blocked by the rear door 31. Thereby, the detector 24 detects the protrusion of the vehicle.

  When the detector 24 detects the protrusion of the vehicle, the protrusion detection signal c is input to the second control device 34. Thereby, since the 2nd control apparatus 34 sends the stop instruction | command d to the drive devices 7 and 22, the drive devices 7 and 22 are stopped. This stops the machine operation.

  In the above, when the rear door 31 of the ordinary vehicle 4 placed on the pallet 9 on the lift cage 2 is not opened at the time of warehousing, or when the rear door 31 is closed from the opened state as shown in FIG. Since the light 27 received by the light receiver 26 is not blocked, the protrusion detection signal c is not sent from the detector 24 to the second control device 34. Therefore, a normal warehousing process is performed in the parking device, and the lift cage 2 is lifted through the suspension member 8 by driving of the driving device 7.

  When the ordinary vehicle 4 to be stored is to be stored in the uppermost storage shelf 4a of FIG. 7, the lift cage 2 is raised to the height position of the uppermost storage shelf 4a. At this time, the detector 24 provided in the lift cage 2 raised is arranged at the second protrusion detection position H2 by the actuator 29. Since the second protrusion detection position H2 is a position slightly higher than the vehicle height section of the ordinary vehicle 4, the detector 24 does not interfere with the ceiling portion of the uppermost storage shelf 4a. Thereby, the ordinary vehicle 4 conveyed by the lift cage 2 can be stored in the uppermost storage shelf 4a from the lift cage 2 and parked.

  During the raising of the lift cage 2 or when the lift cage 2 is raised to the height of the uppermost storage shelf 4a, the rear door 31 of the ordinary vehicle 4 that enters the vehicle due to shocks or vibrations opens and jumps up. When the detector 24 detects the protrusion of the vehicle, the drive device 7 is immediately stopped by the stop signal from the second control device 34. Therefore, if the rear door 31 is open when the ordinary vehicle 4 is laterally fed from the lift cage 2 to the upper storage shelf 4a and stored, the opened rear door 31 may interfere with the steel frame or other devices. There is, but can prevent that fear.

  Next, when the vehicle to be stored is the high roof vehicle 5 having a high vehicle height, the pallet 9 is called from the storage shelf 5 a onto the lift cage 2. Accordingly, a control command b is given from the first control device 32 to the actuator 29, and the detector 24 is arranged at the first protrusion detection position H1.

  As a result, on the lift cage 2, the beam-like light 27 projected from the light projector 25 is received by the light receiver 26 above the high roof vehicle 5 that has entered the pallet 9.

  Accordingly, the rear door 31 is opened by impact or vibration until the high roof vehicle 5 is transported by the lift cage 2 and stored in the target storage shelf 5a, and is moved upward beyond the vehicle height section of the storage shelf 5a. When the projecting state is reached, the vehicle 24 of the high roof vehicle 5 is detected by the detector 24. The processing after the detector 24 detects the protrusion is the same as that for the ordinary vehicle 4.

  When the vehicle to be stored is the middle roof vehicle 6, as in the case of the ordinary vehicle 4 and the high roof vehicle 5, the expansion / contraction stroke of the actuator 29 is controlled by the control command b from the first control device 32, and the detector 24 is arranged at the third protrusion detection position. Thus, when the middle roof vehicle 6 is being moved in, when the rear door 31 of the middle roof vehicle 6 is opened and flipped up, the detector 24 protrudes upward beyond the vehicle height section of the storage shelf 6a. Since the light receiver 26 cannot receive the light 27, the vehicle of the middle roof vehicle 6 is detected. The processing after the detector 24 detects the protrusion is the same as that for the ordinary vehicle 4.

  As described above, the detector 24 can be installed at the first protrusion detection position H1, the second protrusion detection position H2, or the third protrusion detection position by the expansion / contraction operation by the actuator 29. 4. The vehicle overhang detection of the high roof vehicle 5 and the middle roof vehicle 6 can be performed by the common detector 24, and there is no need to prepare a detector for each vehicle height section of the storage shelves 4a, 5a, 6a. There is.

  Further, in the present embodiment, the storage shelves 4a and 6a cannot store vehicles having a vehicle height exceeding the vehicle height category, but the normal vehicle 4 can be stored in the storage shelf 6a for the middle roof vehicle 6 or the high roof. It is possible to store the ordinary vehicle 4 and the middle roof vehicle 6 in the storage shelf 5a for the vehicle 5. In this case, instead of the automatic control of the height position of the detector 24 by the first control device 32 described above, for example, an administrator of the parking device or a driver of the vehicle is attached to the vehicle on the pallet 9. Depending on the corresponding vehicle height class, the height position of the detector 24 may be operated to be arranged at the second protrusion detection position H2 or the third protrusion detection position.

  Further, when the vehicle entering from the entrance / exit 23 is lifted by the lift cage 2, the parking device shown in FIG. 7 needs to turn the vehicle entering from the entrance / exit 23 together with the pallet 9 by 90 degrees.

  When the vehicle is turned together with the pallet 9, the pallet 9 is turned up after being lifted above the position supported by the support member 10a of the lift cage 2. In this case, the pallet 9 is turned by 90 degrees after being lifted by, for example, about 300 mm by the turning device 14.

  A vehicle that is lifted about 300 mm together with the pallet 9 for turning may cause the rear door to open in this state. Therefore, it may be desired to detect protrusion due to opening of the rear door of the turning vehicle. In this case, in the parking device that can store the normal vehicle 4, the high roof vehicle 5, and the middle roof vehicle 6, respectively, with respect to the first protrusion detection position H1, the second protrusion detection position H2, and the third protrusion detection position. Each detection at a position 300 mm higher is required.

  In this regard, in this embodiment, when the vehicle is turned by the turning device 14, the height position of the detector 24 corresponding to each of the ordinary vehicle 4, the high roof vehicle 5, and the middle roof vehicle 6 is set to 300 mm by controlling the actuator 29. All you have to do is adjust to shift to the higher side.

[Second Embodiment]
FIGS. 8A, 8B to 10 show a second embodiment of the parking apparatus. In this embodiment, the same components as those shown in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  FIG. 8A is a schematic side view showing a state in which a spring serving as an expansion / contraction mechanism in the present embodiment extends upward, and FIG. 8B is a schematic side view of FIG. 8A viewed from an angle different by 90 degrees. FIG. FIG. 9A is a schematic side view showing a state in which the spring is shortened, and FIG. 9B is a schematic side view of FIG. 9A viewed from an angle different by 90 degrees. FIG. 10 is a control block diagram.

  The parking apparatus of this embodiment uses a spring 38 instead of the actuator 29 in the first embodiment as an expansion / contraction mechanism, as shown in FIGS. ing. Furthermore, each detector support bracket 28a has a configuration in which a detector 24a disposed at the first protrusion detection position H1 and a detector 24b disposed at the second protrusion detection position H2 are attached. This is an example, and is not shown in the same manner as in the first embodiment, but another detector may be further provided at the third protrusion detection position.

  Similarly to the detector 24 of the first embodiment, the detectors 24a and 24b include a light projector 25 and a light receiver 26 (see FIG. 2) arranged diagonally, and a beam-like shape projected from the light projector 25. When the light 27 is blocked by the rear door 31 (see FIG. 1), it can be detected that the rear door 31 is opened and jumped up and protrudes upward.

  In the present embodiment, as shown in FIG. 10, the protrusion detection signal c of the detectors 24 a and 24 b is input to the second control device 34.

  When the pallet 9 called from the storage shelf 4a (see FIG. 7) for the ordinary vehicle 4 is mounted on the lift cage 2 in the second control device 34 in the present embodiment, the second detection device 34 outputs the protrusion detection signal c of the detector 24b. Based on this, a function of sending a stop command d to the drive units 7 and 22 is provided. At this time, the signal input from the detector 24a to the second controller 34 is invalid.

  Further, when the pallet 9 called from the storage shelf 5a (see FIG. 7) is mounted on the lift cage 2, the second control device 34, based on the protrusion detection signal c of the detector 24a, 22 is provided with a function of sending a stop command d. Therefore, at this time, the signal input from the detector 24b to the second controller 34 is invalid.

  Further, when another detector (not shown) is provided at the third protrusion detection position, the pallet 9 called from the storage shelf 6a (see FIG. 7) is mounted on the lift cage 2 in the second controller 34. In this case, a function of sending a stop command d to the driving devices 7 and 22 based on the protrusion detection signal of another detector may be provided.

  As shown in FIGS. 8A and 8B, the detector 24a is attached to the upper end side of the detector support bracket 28a. Therefore, the detector 24b is attached to the detector support bracket 28a at a position lower than the attachment position of the detector 24a.

  The detector support bracket 28a is attached to each vertical frame 13 of the lift cage 2 (see FIG. 1) via a guide rail 39 and a guide block 40 extending in the vertical direction so as to be movable in the vertical direction. A hook 41 and a downwardly extending guide bar 42 are attached to the lower end of each detector support bracket 28a.

  Each vertical frame 13 is provided with a bracket 43 projecting in the horizontal direction and a stopper 44 that engages with the flange 41 and determines the stroke end on the rising side of the detector support bracket 28a.

  The bracket 43 is provided with a guide rod insertion hole 47 through which the guide rod 42 is inserted, and the guide rod 42 is inserted into the guide rod insertion hole 47 from above. The spring 38 is interposed between the bracket 43 and the flange 41 while being fitted on the outside of the guide bar 42. Thereby, the spring 38 is biased in the direction of pushing up the detector support bracket 28a.

  The stopper 44 is attached above the bracket 43. The distance between the bracket 43 and the stopper 44 is a dimension obtained by adding the dimension of the height difference between the first protrusion detection position H1 and the second protrusion detection position H2 to the dimension when the spring 38 is compressed and shortened. Is set to

  Accordingly, as shown in FIGS. 9A and 9B, the upper end of the detector support bracket 28a is provided on the ceiling 45 side of the uppermost storage shelf 4a (see FIG. 7) while the lift cage 2 is raised. Thereafter, even if the lift cage 2 continues to rise, the rise of the detector support bracket 28a is suppressed. At this time, the lowering of the detector support bracket 28 a relative to the lift cage 2 is absorbed by the compression of the spring 38. Next, when the lift cage 2 rises to the position of the uppermost storage shelf 4a, the detector 24a is arranged at the second protrusion detection position H2 on the lift cage 2.

  Further, as shown in FIGS. 9A and 9B, each vertical frame 13 has a lower end of the guide bar 42 positioned near the lower end of the guide bar 42 with the spring 38 shortened. A proximity sensor 48 for detection is installed. As shown in FIG. 10, when the proximity sensor 48 is turned on, a signal e is sent to the control device 49 described later.

  When the proximity sensor 48 is turned on and the signal e is input, the control device 49 detects the detector 24a even if the pallet 9 called from the storage shelf 4a is mounted on the lift cage 2. Is provided with a function to give the second control device 34 a command f for switching the function so that the protrusion detection signal c input to the second control device 34 is valid and the protrusion detection signal c of the detector 24b is invalidated. Yes.

  Thereby, in the state where the lift cage 2 is raised to the position of the uppermost storage shelf 4a, the second control device 34 determines whether or not the protrusion is present based on the signal of the detector 24a. Therefore, if the rear door 31 is open when the ordinary vehicle 4 is laterally fed from the lift cage 2 to the upper storage shelf 4a and stored, the opened rear door 31 may interfere with the steel frame or other devices. However, this embodiment can also prevent this fear.

  On the other hand, when the lift cage 2 starts to descend from the position of the uppermost storage shelf 4a, the detector support bracket 28a rises relative to the lift cage 2 due to the restoring force of the spring 38 from the compressed state. As shown in 8 (a) and 8 (b), when the collar 41 hits the stopper 44, the rise stops at that position. Therefore, on the lift cage 2, the detector 24a is disposed again at the first protrusion detection position H1, and the detector 24b is again disposed at the second protrusion detection position H2. Further, the proximity sensor 48 is turned off as the detector support bracket 28a is raised. For this reason, since the command f from the control device 49 is not input to the second control device 34, in the second control device 34, the processing based on the protrusion detection signal c of the detectors 24a and 24b is restored to the initial state. .

  Since the parking apparatus of this embodiment has the above-described configuration, the case where the vehicle to be stored is the ordinary vehicle 4 and is stored in the uppermost storage shelf 4a in FIG. 7 will be described.

  A normal vehicle placed on the pallet 9 (see FIG. 1) on the lift cage 2 from the loading / unloading port 23 shown in FIG. 7 is lifted by the lift cage 2 wound up by the drive device 7 shown in FIG. In this state, the spring 38 extends as shown in FIGS. 8A and 8B, and the detector 24b is disposed at the second protrusion detection position H2. In this state, if the rear door 31 (see FIG. 1) opens and jumps upward while the lift cage 2 is being lifted, the detector 24b detects the vehicle protrusion, and based on the protrusion detection signal c, 2 The control device 34 stops the driving device 7 in the same manner as in the first embodiment.

  Next, when the lift cage 2 rises and the lift cage 2 reaches near the uppermost storage shelf 4a shown in FIG. 7, as shown in FIGS. 8 (a) and 8 (b), the detector support bracket 28a The upper end approaches the protrusion 46 of the ceiling part 45. When the lift cage 2 further rises in this state, the upper end of the detector support bracket 28 a comes into contact with the lower surface of the protrusion 46.

  If the detector support bracket 28a to which the detectors 24a and 24b are attached is fixed to the lift cage 2, if the upper end of the detector support bracket 28a interferes with the ceiling portion 45, the lift cage 2 is moved further. Since it cannot be raised, the ordinary vehicle 4 cannot be stored in the storage shelf 4a for the uppermost ordinary vehicle 4 as shown in FIG.

  In this respect, in this embodiment, even after the upper end of the detector support bracket 28a hits the protrusion 46, the lift cage 2 continues to rise by lowering the detector support bracket 28a relative to the lift cage 2. The lift cage 2 can be raised to the position of the uppermost storage shelf 4a.

  At this time, the detector 24a and the detector 24b are displaced to the lift cage 2 side from the first protrusion detection position H1 and the second protrusion detection position H2 by the size corresponding to the shortening of the spring 38, respectively. Therefore, the detector 24a is placed at the second protrusion detection position H2 where the detector 24b was originally placed.

  For this reason, in this embodiment, it switches so that the vehicle 24 of the normal vehicle 4 until it stores in the storage shelf 4a from the lift cage 2 may be detected with the detector 24a.

  As described above, in the present embodiment, the detector support bracket 28a can be moved relative to the lift cage 2 in accordance with the expansion and contraction of the spring 38, so that the detection support bracket 28a is positioned on the upper end side of the detector support bracket 28a. Even if the detector 24a and the detector 24b are respectively attached and the upper end of the detector support bracket 28a interferes with the ceiling portion 45, the ordinary vehicle 4 can be stored in the uppermost storage shelf 4a.

  The present invention is not limited to only those of the above embodiments. For example, FIG. 1 to FIG. 3 show an example of the lift cage 2 and are not limited to the illustrated configuration. For example, the present invention may be applied to a parking device in which the turning device 14 is not mounted on the lift cage 2. The vehicle is not limited to the type in which the vehicle is mounted on the lift cage 2 together with the pallet 9 and transported, and the vehicle is directly mounted on the comb-type lift cage and transported, and then placed on the comb-type pallet called from the storage shelf. Instead, the present invention may be applied to a parking device that accommodates a vehicle. Furthermore, although it has been explained that the state in which the rear door 31 of the vehicle is flipped upward and protrudes upward can be detected, it is similarly detected when the trunk lid is opened and protrudes upward in a vehicle having a rear trunk. Of course you can.

  8A, 8B, and 9A, 9B, as an example, the configuration in which the expansion and contraction of the spring 38 is guided by the guide rod 42 extending downward from the lower end of the detector support bracket 28a is shown. The present invention is not limited to this, and any means other than those illustrated may be used as long as the expansion and contraction of the spring 38 can be guided.

  In the first embodiment, a case has been described in which the vehicle is inserted from the lateral direction of the lift cage 2 and placed on the pallet 9 on the turning device 14 at the time of warehousing, and the vehicle is turned 90 degrees together with the pallet 9. Of course, the present invention can be applied to a parking apparatus of a type that directly enters the pallet 9 on the lift cage 2.

  Of course, various modifications can be made without departing from the scope of the present invention.
