Description

  In the present invention, when a door or a door mirror of a vehicle that has entered a pallet for loading a vehicle in a vertical circulation parking device protrudes from the pallet, the vertical used for detecting the protrusion of the door or door mirror from the pallet. The present invention relates to a protrusion and a door mirror of a circulating parking apparatus.

  As one of the facilities for efficiently parking a vehicle on a limited site, there is a vertical circulation type mechanical parking device (hereinafter referred to as a vertical circulation parking device) called a so-called tower parking.

  In this type of vertical circulation parking apparatus, as shown in FIG. 4, a vehicle storage space 2 is formed in a building 1 standing on the ground, and 1 of the building 1 serving as a lower end portion of the vehicle storage space 2. Although not shown in the figure, a vehicle that has a lower entry system in which the vehicle 4 is loaded into and unloaded from the vehicle storage space 2 through the loading / unloading port 3 provided in the front of the central portion in the width direction of the floor portion. An upper entry system in which a storage space is provided in the basement and the vehicle is stored in and out of the vehicle storage space through an entrance / exit port provided in a ground floor portion which is an upper end portion of the vehicle storage space; A pit extending in the vertical direction is provided in the basement of the building erected on the ground, and a vehicle storage space that is continuous in the vertical direction is divided between the ground and the base in the building and the pit. Of the building that is the middle in the vertical direction Through the entry and leaving port formed in a middle layer, such as a floor portion to the vehicle storage space, there is an intermediate-ride input scheme so as to entry and leaving the vehicle.

  Of the above-mentioned entry-type vertical circulation parking apparatuses, for example, the internal configuration of the vehicle storage space 2 in the lower entry-type vertical circulation parking apparatus is as shown in FIG. A pair of front and rear upper sprockets 6 rotatably attached to an upper frame 5 provided at the top of 2, and a pair of front and rear lower sprockets 8 rotatably attached to a lower frame 7 provided at the lower part of the vehicle storage space 2. A pair of front and rear driving main chains 9 are wound endlessly between the upper and lower sprockets 6 by a driving device 10 such as a motor. It can be circulated in the direction. Furthermore, a plurality of attachments 11 are attached to each main chain 9 at a required interval in the longitudinal direction, and a plurality of cages 13 holding pallets 12 for loading vehicles are attached to the respective attachments 11. Each of them is attached so as to be swingable via a suspension shaft 14 that horizontally protrudes in the front-rear direction provided in the part (see, for example, Patent Document 1).

  In addition, the arrow 3 is an entrance / exit. Reference numeral 15 denotes a chain rail for guiding the main chain 9. In FIG. 5, the cage 13 and the pallet 12 attached to portions other than the upper and lower ends in the circumferential direction of the main chain 9 are not shown.

  By the way, in the type of parking apparatus in which the vehicle to be parked is placed on the pallet at the entrance / exit, and then the vehicle is transferred to the storage space together with the pallet, it is used for getting on and off both sides of the vehicle placed on the pallet. If the door is opened during the transfer of the vehicle and protrudes from the pallet due to the door being in a half-door state, the door contacts the parking device and the door itself is damaged, or the parking device There is a possibility that damage may occur on the side, and there is also a concern that other incoming vehicles may be damaged.

  Therefore, in recent years, as one of the means for preventing the vehicle door placed on the pallet as described above from protruding from the pallet, the driver's It has been proposed to provide a door protector that falls down when getting on and off and automatically stands up when the driver moves away from the vehicle and stores the vehicle (see, for example, Patent Document 2).

  In an elevator-type parking apparatus in which the vehicle is transported to the storage space by moving the vehicle up and down on the platform placed on the ground floor, In order to be able to automatically determine whether or not the vehicle length or width of the vehicle that has entered exceeds the regulations of the parking device, from the ground surface in the four guide rails that guide the lifting of the lifting platform When a vehicle length sensor and a vehicle width sensor are provided at a position slightly higher than the height of the vehicle, the vehicle is placed on the lifting platform and then lifted. When the lifting platform is raised by the height corresponding to the height of the vehicle, if part of the luggage placed in the trunk protrudes or the door mirror or antenna protrudes, remove the protruding object. Inspection It is considered that when the detection is performed, the elevator platform is lowered to the ground surface so that the state of the vehicle can be inspected in a state where the vehicle is returned to the ground surface (for example, (See Patent Document 3).

  However, in the existing vertical circulation parking apparatus, there is no particular measure for the specific measures against the protrusion of the vehicle door or door mirror that has entered the vehicle loading pallet 12 from the pallet 12. The reality is that there is a parking system.

  Therefore, even for the vertical circulation parking apparatus that does not have a measure against the protrusion of the door or door mirror of the storage vehicle from the pallet 12 as described above, the protrusion of the door of the storage vehicle or the door mirror from the pallet 12 can be prevented. It has been desired to make it.

  Therefore, as one of the measures for preventing the door of the warehousing vehicle and the door mirror from protruding from the pallet 12, a door protector as shown in Patent Document 2 is used for loading an existing vertical circulation parking device on the vehicle. It is conceivable to equip the left and right edges of the pallet 12 with retrofit. However, in this case, there is a concern that the tire width of a vehicle that can be placed on the pallet 12 is limited and the vehicle that can be stored may be limited.

  Patent Document 3 describes a method for detecting the protrusion of the vehicle that has entered the elevator platform from the elevator platform in the elevator parking apparatus. And a guide rail provided to guide the vertical lift of the elevator platform at a position corresponding to A vehicle length sensor and a vehicle width sensor are provided at an upper position by the height. Therefore, it cannot be applied as it is to a vertical circulation parking apparatus that does not include the lifting platform or its guide rail.

  Accordingly, the present invention provides a door for a vertical circulation parking apparatus capable of detecting the protrusion when a vehicle door or a door mirror placed on a pallet for loading a vehicle in the vertical circulation parking apparatus protrudes from the pallet. The present invention is intended to provide a door mirror protrusion detection device.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 to FIG. 3 show a case where the present invention is applied to a vertical circulation parking device of a lower entry type as one embodiment of a door and door mirror protrusion detection device of the vertical circulation parking device of the present invention.

  That is, as shown in FIG. 4, the entrance / exit 3 is provided at the center position in the width direction of the first floor portion of the building 1 standing on the ground, and the vehicle storage space 2 inside the building 1 The upper sprocket 6 supported at the front / rear position of the upper frame 5, the lower sprocket 8 supported at the front / rear position of the lower frame 7, and the endless wound around the sprockets 6, 8, respectively. A cage 13 holding a pallet 12 for loading a vehicle via a suspension shaft 14 can swing on a plurality of attachments 11 provided at a required interval in the longitudinal direction of each of the main chains 9. In the lower entry type vertical circulation parking apparatus having an internal structure attached thereto, each cage 13 circulates in the vehicle storage space 2 by circulation driving of the main chain 9. Vertical movement of each cage 13 as it moves vertically along the portion of the cage circulation path 16 that is vertically arranged between the upper and lower sprockets 6 and 8 in the longitudinal direction of the main chain 9. As a photoelectric tube sensor, for example, a light emitting unit 17a and a light receiving unit 17b of a transmissive photoelectric tube sensor 17 are arranged at a predetermined interval in the front-rear direction at positions near the left and right sides of the path 16a, so Attach to the fixed part. As a result, each cage 13 moves vertically in the cage vertical movement path 16a along with the circulation drive of the main chain 9 and passes through the installation location of the transmission type photoelectric tube sensor 17 in the vertical direction. When doors and door mirrors of a vehicle (not shown) placed on a pallet 12 held in a required cage 13 protrude from the left and right ends of the pallet 12, the doors and door mirrors of the vehicle 4 protruding from the pallet 12 are displayed. Therefore, the irradiation light 18 radiated from the light emitting portion 17a of the transmissive photoelectric tube sensor 17 toward the light receiving portion 17b is blocked.

  Details will be described below.

  Here, paying attention to the circulation paths 16 of the cages 13 in the lower entry type vertical circulation parking apparatus, the circulation paths 16 of the cages 13 are arranged in the longitudinal direction of the main chain 9 as schematically shown in FIG. And a lower sprocket in the longitudinal direction of the main chain 9 in which the cage 13 turns semicircularly around the upper half of the upper sprocket 6 as the portion of the upper sprocket 6 moves. 8, the cage 13 turns around the lower half of the lower sprocket 8 in a semicircular manner along with the movement of the portion of the lower sprocket 8, and the left and right sides of the upper and lower cage turning routes 16 a and 16 b. Transfer between the upper and lower sprockets 6 between the upper and lower sprockets 6 in the longitudinal direction of the main chain 9 between both ends. Accompanied is in the cage 13 is formed from a cage vertical moving path 16a that moves in a vertical direction.

  By the way, when the door of the vehicle is in a half-door state, it is considered that if a change occurs in the moving speed of the vehicle in the left-right direction, an inertial force acts on the door in the half-door state and the door is easily opened. Therefore, in the lower entry type vertical circulation parking apparatus, the cage 13 holding the pallet 12 on which the half-door vehicle is placed is connected to the upper cage turning movement path 16b that moves in the left-right direction, It is assumed that when the vehicle passes through the lower cage rolling movement path 16c, the door of the vehicle is easily opened from the half-door state.

  Further, in the lower entry type vertical circulation parking apparatus, a vehicle entering through the entrance / exit 3 enters the pallet 12 held by the cage 13 stopped at the lowermost part of the lower cage turning movement path 16c. Therefore, the cage 13 holding the pallet 12 in which the warehousing vehicle is placed is the lower cage, even when the main chain 9 is circulated in the clockwise or counterclockwise direction in the figure. It reliably passes through the turning movement path 16c. Further, when the door mirror of the vehicle protrudes from the corresponding pallet 12 due to forgetting to store the door mirror of the vehicle that has entered the pallet 12 held in the cage 13 arranged inside the entrance / exit 3 The early detection is desired.

  In view of these, in the present embodiment, the transmissive photoelectric tube sensor 17 is placed on both the left and right sides of the lower end portion of the left and right cage vertical movement paths 16a that are located immediately above the left and right ends of the lower cage rolling movement path 16c. It is arranged in the vicinity.

Specifically, in the vertical circulating type parking apparatus of the lower-ride input method, so as to correspond to the vehicle storage space 2 near the center position of the lower end portions of the left and right of the cage vertical moving path 16a, the lower portion of the vehicle storage space 2 In the required attachment point slightly above the lower sprocket 8 in the provided lower frame 7 in the front-rear direction, the left and right end portions extend slightly above the required attachment point in the lower frame 7 and extend in the left-right direction. For example, a vehicle in which two brackets 19 that are close to the end of the pallet 12 near the center of the vehicle storage space 2 held by the cage 13 moving on the left and right cage vertical movement paths 16a are placed on each pallet 12, for example. Of the doors on both sides of the door at a required interval in the front-rear direction so as to be positioned in front of and behind the door provided with the door mirror Put Ri. Furthermore, the light projecting portion 17a and the light receiving portion 17b of the transmission type phototube sensor 17 are respectively installed on the left and right end portions of the front and rear brackets 19 so as to face each other in the front-rear direction.

Of the columns 20 provided at the four corners of the building 1, the left and right cages of the left and right beams 21 are connected to each other at the required height position of the building 1. The left and right cage vertical movement paths at a height position substantially corresponding to the mounting position of the transmission phototube sensor 17 in the lower frame 7 so as to correspond to the position closer to the outside of the vehicle storage space 2 at the lower end of the vertical movement path 16a. At the end of the pallet 12 that is held by the cage 13 that moves on the left and right cage vertical movement paths 16a, at the end closer to the outside of the vehicle storage space 2 below the beam 21 that is disposed on the left and right outside of the lower end of 16a. Brackets 22 that protrude into the vehicle storage space 2 so as to be close to each other are attached to the front and rear brackets 19 provided on the lower frame 7 at two front and rear positions so as to be aligned in the left-right direction. The projecting end portions of the front and rear brackets 22 are configured such that a light projecting portion 17a and a light receiving portion 17b of the transmissive photoelectric tube sensor 17 are disposed facing each other in the front-rear direction.

  In FIG. 1, reference numeral 23 denotes a beam on both the front and rear sides connecting the columns 20 arranged in the left-right direction among the columns 20 provided at the four corners of the building 1, and 24 denotes the beams on the left and right sides at the corner portion of the building 1. 21 and a connecting member that connects adjacent ends of the beams 23 on both the front and rear sides. Other components that are the same as those shown in FIG.

  In FIG. 1, the outer wall of the building 1 is not shown. In FIG. 2, the description of the beams 21 on both the left and right sides of the building 1 other than the beam 21 to which the transmission type photoelectric tube sensor 17 is attached is omitted.

  In the case of using the door of the vertical circulation parking apparatus and the door mirror protrusion detection device having the above-described configuration, the light emitting unit 17a of the transmission photoelectric tube sensor 17 is irradiated with the predetermined irradiation light 18 from the light receiving unit 17b. The lower entry type vertical circulation parking device is operated, and the light receiving unit 17b of the transmission type photoelectric tube sensor 17 can receive the irradiation light 18 irradiated from the light projecting unit 17a. When it disappears, the circulation drive of the main chain 9 through the rotational drive of the upper sprocket 6 by the drive device 10 (see FIG. 5) of the lower entry type vertical circulation parking device can be immediately stopped. . Thereby, after entering the vehicle on the pallet 12 held by the cage 13 disposed inside the entrance / exit 3 through the entrance / exit 3 of the lower entry type vertical circulation parking device, If the driver of the vehicle exits without retracting the door mirror, then the upper sprocket 6 is driven to rotate by the drive device 10 and the main chain 9 is circulated to drive the vehicle that does not store the door mirror. After the cage 13 holding the loaded pallets 12 is moved from the lower cage rolling movement path 16c to the left or right cage vertical movement path 16a, the cage 13 starts to rise in the cage vertical movement path 16a. At this time, when the door mirror that is not stored in the vehicle protrudes from the left and right ends of the pallet 12, the transmission phototube is reached when the door mirror reaches the installation height position of the transmission phototube sensor 17. Since the irradiation light 18 applied to the light receiving unit 17b is shielded from the light projecting unit 17a of the sensor 17, based on the output of the transmissive photoelectric tube sensor 17, the driving device 10 is responsible for the upper sprocket 6 via the upper sprocket 6. The circulation drive of the chain 9 is immediately stopped. As a result, the door mirror protruding from the pallet 12 of the vehicle is surely prevented from coming into contact with a member of the parking device or in contact with another vehicle thereafter.

  Similarly, when the vehicle driver leaves the pallet 12 held by the cage 13 disposed inside the loading / unloading port 3 from the loading / unloading port 3 and the driver of the vehicle leaves in a half-door state, After that, when the upper sprocket 6 is driven to rotate by the driving device 10 and the main chain 9 is driven to circulate, the cage 13 holding the pallet 12 loaded with the vehicle in the half-door state is rotated around the lower cage. After being moved from the path 16c to the left or right cage vertical movement path 16a, the ascending is started in the cage vertical movement path 16a. When the door in the half-door state is opened and protrudes from the pallet 12 due to the change in the moving speed of the vehicle in the left-right direction generated at this time, the door protruding from the pallet 12 Since the irradiation light 18 applied to the light receiving unit 17b from the light projecting unit 17a of the transmissive photoelectric tube sensor 17 is blocked when the installation height position is reached, based on the output of the transmissive photoelectric tube sensor 17. Then, the circulation drive of the main chain 9 via the upper sprocket 6 by the driving device 10 is immediately stopped. Therefore, the door protruding from the pallet 12 is reliably prevented from coming into contact with a member of the parking device or in contact with another vehicle thereafter.

  As described above, when an emergency stop of the drive device 10 occurs based on the output of the transmissive photoelectric tube sensor 17, a maintenance worker of the parking device enters the parking device and the transmissive photoelectric tube sensor. When the installation location 17 is reached, it is possible to easily confirm the light that is irradiated from the light projecting portion 17a of the transmissive photoelectric tube sensor 17 to the light receiving portion 17b. If the door mirror is a vehicle door mirror, the door mirror is retracted. If the door that blocks the irradiation light 18 is an open door, the door is securely closed, etc. After confirming the cause of blocking the irradiation light 18 and taking measures to prevent the cause from protruding from the pallet 12, the driving device 10 resumes circulating driving of the main chain 9 It should be so.

  Thus, according to the door and the door mirror protrusion detection device of the vertical circulation parking apparatus of the present invention, the door of the vehicle that has entered the lower entry vertical circulation parking apparatus is opened from the half-door state, and the pallet 12 is opened. Even when a door mirror that protrudes or is not stored protrudes from the pallet 12, the door 13 immediately after the cage 13 holding the pallet 12 loaded with the vehicle reaches the left and right cage vertical movement paths 16a. Further, the transmissive photoelectric tube sensor 17 can detect the protrusion of the door mirror from the pallet 12. Accordingly, if the operation of the lower entry type vertical circulation parking device is immediately stopped based on the output of the transmission photoelectric tube sensor 17, the vehicle door or door mirror that protrudes from the pallet 12 thereafter. Can surely prevent the vehicle from coming into contact with the parking device or with other vehicles, so that the doors and door mirrors of the vehicle, the parking device, and other vehicles stored in the parking device are damaged. The effect which prevents the possibility that this may occur can be expected.

  The present invention is not limited to the above embodiment, and the light emitting portion 17a and the light receiving portion 17b of the transmissive photoelectric tube sensor 17 may be arranged in the front-rear direction corresponding to the front and rear end portions of the pallet 12. Good. In this way, in addition to the door to which the door mirror of the warehousing vehicle is attached as described above, for example, when the rear door of a four-door vehicle opens from the half-door state and protrudes from the pallet 12, the pallet 12 The protruding rear door can be detected. Moreover, you may make it replace the installation position of the light emission part 17a and the light-receiving part 17b of the said transmission type photoelectric tube sensor 17 back and forth.

  From the viewpoint of early detection of the protruding of the door and door mirror from the pallet of the incoming vehicle of the lower-entry-type vertical circulation parking device, the transmissive photoelectric tube sensor 7 is an entrance / exit in the left and right cage vertical movement paths 16a. Although it is desirable to provide it at both the left and right side positions near the lower end close to 3, it may be changed in the vertical direction as long as it is at the left and right side positions of the left and right cage vertical movement paths 16a. Further, in addition to the lower ends of the left and right cage vertical movement paths 16a, the transmission type photoelectric tube sensor 17 may be disposed at both the left and right positions of the upper ends of the left and right cage vertical movement paths 16a. In this way, the door of the vehicle in a half-door state placed on the pallet 12 held in a certain cage 13 does not open when the cage passes through the lower cage rolling movement path 1c, and the cage 13 Is opened when it is moved to the upper cage rolling movement path 16b by the circulation drive of the main chain 9, the cage 13 causes the left and right cage vertical movement paths to protrude from the pallet 12 of the opened door. It becomes possible to detect quickly when it moves to the upper end of 16a.

  Furthermore, the present invention can also be applied to an upper boarding system or an intermediate boarding type vertical circulation parking apparatus. Of these, in the upper-entry type vertical circulation parking device, the entrance / exit 3 is provided in the cage circulation path 16 at a position corresponding to the upper end of the upper cage rolling movement path 16a. It is desirable to provide the transmission type photoelectric tube sensor 17 at both the left and right positions of the upper end portion of the cage vertical movement path 16a near the entrance / exit 3. Further, in the case of an intermediate boarding type vertical circulation parking device, for example, the transmissive photoelectric tube sensors 17 may be provided at the left and right positions of the upper and lower ends of the left and right cage vertical movement paths 16a.

  Although the transmissive photoelectric tube sensor 17 has been exemplified as the photoelectric tube sensor, a reflective photoelectric tube sensor may be provided. In this case, the main body of the reflection type phototube sensor including the light emitting unit and the light receiving unit and the reflector may be installed in the same arrangement as the light emitting unit 17a and the light receiving unit 17b of the transmission type phototube sensor 17.

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