As shown in the figure, the boarding and landing room 29 is provided on the same floor as the parking space 80 outside the store. Further, as will be described in detail below, the mechanical parking lot 10 according to the present embodiment does not rotate the vehicle 70 in the boarding and lowering chamber 29, but rotates in the B2 step-down path and the vehicle rack 12. Therefore, in the mechanical parking lot 10 according to the present embodiment, the occupied area occupied by the 1F boarding and landing chamber 29 can be reduced. FIG. 8(D) shows a configuration in which the vehicle 170 is rotated in the conventional boarding and landing chamber 129. The mechanical parking lot is used for comparison with the mechanical parking lot 10 related to the present embodiment. In the conventional mechanical parking lot in which the vehicle 170 is rotated in the boarding and landing chamber 129, it is necessary to install a rotation space in which the tray 1 19 is rotated in the boarding and landing chamber 129 (in the figure, a CR space indicated by a one-point lock line) . Therefore, the area occupied by the boarding and lowering chamber 129 of 1F becomes large (especially, the width in the XI and X2 directions becomes large), and the parking space outside the parking space 80 having a high price is narrowed by the boarding and lowering chamber 129. In the present embodiment shown in Fig. 8(C), since the tray 19 (vehicle 70) is not rotated in the boarding and landing chamber 29, the occupied area of the boarding and lowering chamber 29 of 1F is narrowed, and a large addition can be obtained. The price of the parking lot outside the high price is 80. Further, the mechanical parking lot 1 according to the present embodiment is a tray type parking lot using the tray 19. In the tray-type mechanical parking lot 10, the vehicle 70 is parked in the vehicle rack 12 by means of the elevator 11 so that the tray 19 in which the vehicle 70 is loaded is moved up and down or moved in the surface direction. Hereinafter, the specific configuration of the mechanical parking lot will be described. As shown in FIGS. 1 to 4, the mechanical parking lot 10 is roughly provided by a tray 19 of the stowage vehicle 70, an elevator 11 for lifting the tray 19, and a vehicle 70 placed with the tray 19 (parked). The vehicle is placed in a shelf 12 or the like. Further, the elevator 11 is a first tray transfer device y21 that transfers (moves) the tray 19 between the elevator 11 and the vehicle rack 12 by the elevator frame 20 on which the tray 19 is mounted, and lifts and drives the elevator. The liter device 22 of the frame 20 is constructed. Further, the mechanical parking lot 10 has a control system including various sensors 72, 73, 76 to 78, and a control device 85 shown in Fig. 10, and the first tray transfer device 21 and the lifting device 22 The rotating device 23 and the second tray transfer device 45 are configured to be driven and controlled by the control system. First, the tray 19 will be explained. The tray 19 is a vehicle in which the vehicle 70 is stowed, and has a rectangular shape in a plan view. The tray 19 is mounted on the upper portion of the elevator frame 20. Specifically, in the upper portion of the elevator frame 20, a rotating device 23 is mounted as will be described later, and a first tray transfer device 21 is disposed on the upper portion of the rotating device 23. The tray 19 is lifted and lowered in a state of being mounted on the upper portion of the first tray transfer device 21. Further, the tray 19 used in the present embodiment is a configuration in which only one of the vehicle stoppers 19a (shown in FIG. 3 in the solid line) is disposed in one place (a so-called normal tray). However, in addition to the vehicle stopper 19a, the so-called reversible type of the vehicle stopper 19b (shown in FIG. 3 with a slight lock line) can be used in a position where the tray 19 is symmetrical with the stopper 19a in the front-rear direction.托-10-1361240 disk. When the reversible tray is used, when the tray 19 is rotated by the elevator hoistway 14 as will be described later, it can be rotated irrespective of its directivity. Therefore, when the reversible tray is applied, the vehicle 70 does not need to rotate the tray 180° after leaving the warehouse, and the warehousing process of the next vehicle 7 可 can be directly performed continuously, so that the smoothness of the vehicle 70 entering and leaving the warehouse can be improved.
I 接著’説明有關升降機11。升降機11係被設置在配設 φ 於設置面的地板41上。該升降機η大致是由桅桿15~18、 升降機框20、第1托盤移載裝置21、升降裝置22、旋轉裝 置23、配重30等所構成。 桅桿15~18係立設在設置面13的支柱，本實施形態中 設有4支。但是，桅桿數並非被限定於此者，例如亦可藉 由2支桅桿構成升降機11。 升降機框20係由2支側框20A、連結該2支側框20A的2 支連結框20B所構成。第3圖中的Y2方向側之側框20A，係 • 其一端部被升降自如地支撐在桅桿15，另一端部被升降自 如地支撐在桅桿1 6。且，第3圖中的Y 1方向側之側框20A ，係其一端部被升降自如地支撐在桅桿18，另一端部被升 降自如地支撐在桅桿17。 2支連結框20B係設成連結被分離配設的一對側框20A 。藉此，升降機框20係被支撐在桅桿15〜18進行升降動作 之構成。該升降機框20係於其上部被配設有第1托盤移載 裝置21及旋轉裝置23。 接著，説明有關托盤旋轉裝置23。旋轉裝置23係使托 -11 - 1361240 盤19旋轉者，由旋轉基座69(參照第3圖）、及未出現在 圖中的旋轉用馬達、及驅動齒輪群等所構成。旋轉基座69 係連接在配設於其下部的驅動用齒輪群，且在驅動用齒輪 群連接有旋轉用馬達。因此形成藉由旋轉用馬達驅動的方 式，藉由驅動用齒輪群而被減速處理之外，旋轉基座69被 旋轉驅動之構成。 且，在該托盤旋轉裝置23的旋轉基座69上部，設有進 行托盤19之搭載及移載處理的第1托盤移載裝置21。因此 ’藉由旋轉裝置23驅動，使第1托盤移載裝置21在升降機 框20上轉動（旋轉）的方式，托盤19也相對於升降機框20 進行旋轉動作。本實施形態所相關之旋轉裝置23係可使托 盤19進行180°旋轉之構成。 如此地，藉由可利用旋轉裝置23使托盤19進行180°旋 轉的構成之方式，可使車輛7 0在入庫時對乘降室29以前進 方式入庫，並且使車輛7 0在出庫時也可以前進方式從乘降 室29出庫。因此，可提高入出庫時利用機械式停車場10者 (駕駛者）的方便性。 此外，本實施形態中，由於是入庫位置和出庫位置在 同一位置之構成，因此是使托盤19進行180。旋轉之構成， 但托盤19的旋轉角度並非被限定於此者，於入庫位置和出 庫位置爲相異位置之構成下，也可採用以其他角度旋轉之 構成。具體而言，在乘降室29的托盤19方向和車輛置放架 12内的托盤19方向爲相異方向之構成下，也可採用以對應 該托盤19方向之差的方式使其旋轉之構成。 -12- 1361240 如上述，藉由可180°旋轉托盤19之構成的方式，可提 高使用者（駕駛者）入出庫時之方便性，但如前述地，若 使該托盤1 9之旋轉在乘降室2 9内進行，則附加價値高的停 車場外空間80將變得狹窄。因此本實施形態係使該托盤1 9 的旋轉處理在B2的升降機升降路14内進行之構成。 第4圖係顯示機械式停車場10的B2之車輛置放架12 — 部分放大之俯視圖。同圖中，僅放大顯示在車輛置放架12 φ 内，以圍繞升降機升降路14的方式所配置的8台停車空間 24。在同圖以二點鎖線所示之圓CR，係托盤19以托盤轉動 中心〇爲中心轉動時，平面視形成長方形狀之托盤19的四 隅角所描繪出的圓（稱爲托盤轉動圓CR)。.前述桅桿 15~1 8係設在該托盤轉動圓CR外側，且被設定成不妨礙托 盤1 9旋轉。 且’本實施形態中，如第2圖及第9圖所示，托盤19旋 轉時’旋轉基座69係與車輛置放架12 (具體而言是位在升 Φ 降機升降路I4周圍的停車空間24)在平面上不相干渉之構 成。藉由設定爲該構成之方式，在托盤1 9旋轉時，不須使 旋轉基座69在比車輛置放架12的構成物（例如第2托盤移 載裝置45等）更高的位置旋轉，可以只考慮以托盤19和車 輛置放架12的構成物不相干渉的方式而設定托盤19的旋轉 高度。藉此，可將使托盤19旋轉的位置（高度位置P2)和 使托盤19在與車輛置放架12之間移載的位置（高度位置P3 )之離開距離ΔΗ予以縮小，因此可謀求機械式停車場10 小型化（低背化）。 -13- 1361240 此處，著眼於托盤轉動圓CR時，托盤轉動圓CR係與 升降機升降路14之位於第4圖中的X2方向之停車空間24 ( 特別稱之爲停車空間24A)、及升降機升降路14之位於第4 圖中的XI方向之停車空間24 (特別稱之爲停車空間24B ) ，在平面視呈重疊狀態。因此，設在停車空間24 A ' 24B的 構成物或搭載在停車空間24A、24B的托盤19之高度、和搭 載在位於B2的升降機框20的托盤19之高度爲同一高度時， 托盤19將無法進行旋轉。 因此，本實施形態中，係搭載在升降機框20的托盤19 旋轉時，在旋轉前將停車空間24A、2 4B上的托盤19移載到 _ —-— - ，一 'I then 'describes about the elevator 11. The elevator 11 is provided on the floor 41 on which the φ is disposed on the installation surface. The elevator η is substantially constituted by masts 15 to 18, an elevator frame 20, a first tray transfer device 21, a lifting device 22, a rotating device 23, a counterweight 30, and the like. The masts 15 to 18 are struts that are erected on the installation surface 13, and in the present embodiment, four are provided. However, the number of masts is not limited to this. For example, the elevator 11 may be constituted by two masts. The elevator frame 20 is composed of two side frames 20A and two connecting frames 20B that connect the two side frames 20A. The side frame 20A on the Y2 direction side in Fig. 3 is one end portion which is supported by the mast 15 so as to be lifted and lowered, and the other end portion is supported by the mast 16 in a freely movable manner. Further, the side frame 20A on the Y1 direction side in Fig. 3 is supported by the mast 18 at one end portion, and the other end portion is supported by the mast 17 so as to be freely movable. The two connecting frames 20B are connected to the pair of side frames 20A that are separated and disposed. Thereby, the elevator frame 20 is supported by the masts 15 to 18 to perform the lifting operation. The elevator frame 20 is provided with a first tray transfer device 21 and a rotating device 23 at an upper portion thereof. Next, the tray rotating device 23 will be described. The rotating device 23 is configured such that the tray -11 - 1361240 is rotated by a rotating base 69 (see Fig. 3), a rotating motor not shown in the drawing, a drive gear group, and the like. The rotary base 69 is connected to a drive gear group disposed at a lower portion thereof, and a rotation motor is connected to the drive gear group. Therefore, the rotation base is driven by the rotation of the drive gear group, and the rotary base 69 is rotationally driven. Further, on the upper portion of the rotating base 69 of the tray rotating device 23, a first tray transfer device 21 for carrying in and carrying out the loading of the tray 19 is provided. Therefore, the tray 19 is also rotated with respect to the elevator frame 20 so that the first tray transfer device 21 is rotated (rotated) on the elevator frame 20 by the rotation device 23. The rotating device 23 according to the present embodiment is configured to rotate the tray 19 by 180°. In this manner, by means of the configuration in which the tray 19 can be rotated by 180° by the rotating device 23, the vehicle 70 can be placed in the forward mode for the boarding and landing room 29 at the time of storage, and the vehicle 70 can be placed at the time of delivery. The forward mode is taken out from the boarding and landing room 29. Therefore, the convenience of using the mechanical parking lot 10 (driver) when entering and leaving the warehouse can be improved. Further, in the present embodiment, since the storage position and the delivery position are at the same position, the tray 19 is caused to be 180. Although the rotation angle of the tray 19 is not limited to this, the configuration may be such that the storage position and the storage position are different positions, and the rotation may be performed at other angles. Specifically, in the case where the direction of the tray 19 of the boarding and landing chamber 29 and the direction of the tray 19 in the vehicle rack 12 are different directions, it is also possible to rotate the tray 19 in a direction corresponding to the difference in the direction of the tray 19. . -12- 1361240 As described above, the convenience of the user (driver) entering and leaving the warehouse can be improved by the 180° rotation of the tray 19, but as described above, if the rotation of the tray 19 is multiplied When the descending room is carried out within 29, the space 80 outside the parking lot with a high additional price will become narrow. Therefore, in the present embodiment, the rotation processing of the tray 19 is performed in the elevator hoistway 14 of B2. Fig. 4 is a partially enlarged plan view showing the vehicle rack 12 of the B2 of the mechanical parking lot 10. In the same figure, only eight parking spaces 24 arranged in the vehicle rack 12 φ so as to surround the elevator hoistway 14 are shown in an enlarged manner. In the circle CR shown by the two-point lock line in the same figure, when the tray 19 is rotated about the center of rotation of the tray, the circle drawn by the four corners of the rectangular tray 19 is formed in a plane (referred to as a tray rotation circle CR). . The masts 15 to 18 are disposed outside the tray rotation circle CR and are set so as not to interfere with the rotation of the tray 19. Further, in the present embodiment, as shown in Figs. 2 and 9, when the tray 19 is rotated, the "rotating base 69" and the vehicle rack 12 (specifically, the position around the lift hoisting and lowering path I4) The parking space 24) is made up of a non-coherent plane. By setting this configuration, when the tray 19 is rotated, it is not necessary to rotate the spin base 69 at a position higher than the structure of the vehicle rack 12 (for example, the second tray transfer device 45 or the like). It is possible to set only the rotational height of the tray 19 such that the components of the tray 19 and the vehicle rack 12 are not coherent. Thereby, the position (height position P2) at which the tray 19 is rotated and the distance ΔΗ from the position (height position P3) at which the tray 19 is transferred between the vehicle frame 12 can be reduced, so that the mechanical type can be achieved. Parking lot 10 is miniaturized (low profile). -13- 1361240 Here, focusing on the tray rotation circle CR, the tray rotation circle CR and the elevator hoistway 14 are located in the X2 direction parking space 24 (particularly referred to as the parking space 24A) in FIG. 4, and the elevator The parking space 24 (specifically referred to as the parking space 24B) of the hoistway 14 in the XI direction in Fig. 4 is superimposed in plan view. Therefore, when the height of the structure of the parking space 24 A ' 24B or the tray 19 mounted in the parking spaces 24A and 24B and the height of the tray 19 mounted on the elevator frame 20 of B2 are the same height, the tray 19 cannot be Rotate. Therefore, in the present embodiment, when the tray 19 mounted on the elevator frame 20 is rotated, the tray 19 on the parking spaces 24A and 2BB is transferred to the __---, a ' before the rotation.

Therefore, in the present embodiment, the first position detecting sensor 72 and the second position detecting sensor 73 which are disposed apart from each other in the height direction (Z1, Z2 direction) are provided. When the elevator frame 20 is lowered toward the height position Ρ2, first, the second position detecting sensor 73 disposed at the lower portion engages the light shielding plate 74 to block the light. Therefore, the signal from the second position detecting sensor 73 becomes OFF (because the light is blocked, the signal becomes OFF), whereby the control device 85 can detect that the tray 19 is moved to the height position P2. Further, when the elevator frame 20 is lowered, the first position detecting sensor 72 disposed at a position higher than the second position detecting sensor 73 is higher than Δ, and the other light shielding plate (not shown) is engaged. The light is blocked. Therefore, by means of the signal from the first position detecting sensor 72 being turned OFF, the control unit 85 can detect that the tray 19 has moved to the height position P3. In addition, the detection of other height positions PI, P4, and P5 is also detected by the same detection method as the above method. Further, in the present embodiment, the rotation processing of the tray 19 is performed only in B2, and the tray 19 is not rotated in each of the IF, B3, and B4 buildings. Therefore, in each of the buildings IF, B3, and B4, it is not necessary to perform the detection processing for stopping the elevator frame 20 at a position higher than the transfer position of the tray 19 by a high ΔΗ. The upper limit sensor 76 is set to be disposed on the mast 15, and when the elevator frame 2 0 -20- 1361240 1 is moved to the upper limit position of the mast I 5 , the elevator frame 20 is engaged and the signal is transmitted to the control device 85 . On the other hand, the lower limit sensor 77 is also disposed to be disposed on the mast I5, and when the elevator frame 20 is moved to the lower limit position of the mast 15, the elevator frame 20 is engaged and the signal is transmitted to the control device 85. Further, Fig. 6 used in the above description is a diagram in which the state in which the elevator frame 20 is moved to the upper limit position and the state in which it is moved to the lower limit position are displayed. The tray detecting sensor 78 is disposed in all of the parking spaces 24 provided in the vehicle racks 12 of the Β2 to Β4. The tray detecting sensor 78 is for detecting whether or not the tray 19 is mounted in the parking space 24. Each of the tray detecting sensors 78 is connected to the control unit 85, so that the control unit 85 can detect the presence or absence of the disc in all of the parking spaces 24. Next, the operation of the mechanical parking lot at the time of storage of the vehicle 70 will be described together with the control operation performed by the control device 85. When the vehicle 70 is stored in the mechanical parking lot, the storage operation is performed by an operation panel (not shown) disposed outside the passenger-elevating chamber 29, and the gate 2 7 is opened. After the gate door 27 is opened, the vehicle 70 moves to the tray 19 mounted on the first tray transfer device 21 disposed above the elevator frame 20 (rotating device 23) in the boarding and landing chamber 29. When the vehicle 70 travels toward the tray 19, an inversion moment (a moment indicated by an arrow 第 in Fig. 1) is generated at the end of the tray 19 due to the load of the vehicle 70. Therefore, if this is not the case, the vehicle 70 will be tilted, or the worst case is that the vehicle 70 is reversed. This embodiment is provided with a reverse preventing roller 25 in order to prevent such a situation. The reverse prevention roller 25 is disposed in the middle frame -21 - 1361240 20C provided in the elevator frame 20. The intermediate frame 20C is disposed at a symmetrical position with respect to the center of rotation of the tray I9 of the elevator frame 20 in the directions of Y1 and Y2, and each of the intermediate frames 20C is provided with two reverse preventing rollers 25. Fig. 7 is an enlarged schematic view showing the arrangement position of the reverse preventing roller 25. As shown in the figure, a support member 28 is disposed in the intermediate frame 20C, and the upper portion of the support member 28 is provided with a reverse preventing roller 25. Also, the height of the support member 28 is set to reversely prevent the roller 25 from being rotatably contacted to the height below the tray 19. By installing the reverse prevention roller 25 set as described above, the vehicle 70 travels on the tray 19 at the time of storage, and even if the tray 19 is reversed due to the load of the vehicle 70, the torque Μ will be received by the reverse prevention roller 25. Therefore, it is possible to prevent the tray 19 from being tilted or inverted. Further, the tray 19 is rotated on the elevator frame 20 by the rotating device 23, and the rotation preventing reverse roller 25 is rotated as the rotation of the tray 19 is reversed, so that the reverse rotation preventing roller 25 can also rotate the tray 19 smoothly. Conducted. Further, the height of the reverse prevention roller 25 may be lower than the height of the irrelevant rotation when rotated. The vehicle 70 travels to a predetermined stop position on the tray 19 in the boarding and landing chamber 29 to stop. The driver gets off the vehicle 70, exits from the opening of the grille door 27, and goes outside the boarding and landing chamber 29, and performs the storage operation by an operation panel (not shown). After the control device 85 transmits the inbound operation signal from the operation panel, the shutter gate 27 is first closed. The control unit 85 then drives the lifting device 22 to lower the elevator frame 20. As described above, in the present embodiment, the configuration in which the rotation in the direction of the vehicle 70 is performed is performed on the crucible 2. Further, the elevator frame 20 is provided with first and second position detecting sensors 72 and 1361240 73, and a shutter 74 is provided at a position where the mast 15 corresponds to B2. The light shielding plate 74 is coupled to the second position detecting sensor 73' when the tray 19 reaches the height position P2, and transmits a signal (hereinafter referred to as the P2 signal) that notifies the tray 19 to the height position P2 to the control device 85. . The control unit 85 controls the lifting device 22 so that the elevator frame 20 continues to descend until the P2 signal is transmitted from the second position detecting sensor 73. Then, after the P2 signal is transmitted from the second position detecting sensor 73, the control device 85 stops the φ lifting device 22. Thereby, the tray 19 of the vehicle 70 on which the storage is mounted is stopped at the position of the height position P2 in the elevator hoistway 14. After the warehousing operation signal is transmitted from the operation panel, the control device 85 and the drive control the lifting device 22 simultaneously detect the parking spaces 24A, 24B of the vehicle gantry 12 at B2 (refer to Figs. 4 and 8 ( B)) Whether or not to carry the tray 1 9 . This detection processing is performed based on signals from the tray detecting sensor 78 disposed in the parking spaces 24A, 24B. When it is determined that the trays 19 are mounted in the parking spaces 24A and 24B, the φ control device (1) is mounted on the parking spaces 24A and 24B and the second tray transfer device 45 located in the parking space 24 adjacent thereto. The tray 19 of the parking space 2 4A, 24B is transferred to another parking space 24 that is irrelevant to the tray rotation circle CR. The control device 85 confirms that the tray 19 of the vehicle 70 on which the storage is mounted is stopped at the height position P2 in the elevator lifting path I4. In the case of the position 'and the case where the tray 19 is not present in the parking spaces 24A and 24B, the rotating device 23 is driven to rotate the tray 19 on which the vehicle 70 is mounted at the height position P2. Figures 1 and 2 show that the vehicle 70 is rotated 9 turns. After the state. Further, -23- 1361240 Fig. 9 shows a state in which the tray 19 (vehicle 70 is not shown) is rotated by 135°. This rotation process is performed until the tray 19 is rotated by 180 degrees. Thereby, the direction of the vehicle 70 becomes the opposite direction to the direction in which the boarding and landing chamber 29 travels. Here, as described above, the rotation trajectory when the tray 19 is rotated, that is, the tray rotation circle CR, is overlapped with the parking space 24A and the parking space 24B in a plan view. However, in the present embodiment, the height position P2 at which the tray 19 is rotated is rotated at a height that is independent of the components of the parking spaces 24 A and 24B. At this time, in the present embodiment, before the tray 19 is rotated, the tray 19 on the parking spaces 24A, 24B is transferred to the other parking space 24 which is irrelevant to the tray rotation circle CR, and the rotating base 69 is rotated. Since the parking space 24 is irrelevant, the height position P2 at which the tray 19 can be rotated is close to the height position P3 of the transfer tray 19, that is, the height position P3. Specifically, the departure distance Δ 高度 of the height position P2 and the height position P3 can be extremely close to 7 cm as described above. Thereby, the rotation space necessary for the floor to be rotated (B 2 in the present embodiment) can be reduced, and the accommodating efficiency of the vehicle 70 in the mechanical parking lot can be maintained. Specifically, by making the rotation trajectory of the tray 19, that is, the tray rotation circle CR and the parking spaces 24A and 24B overlapping in plan view, it is possible to realize the small size of the mechanical parking lot 10 especially in the directions of XI and X2 in the figure. Chemical. Further, by transferring the trays 19 of the parking spaces 24A, 24B to the other parking spaces 24 that are not related to the tray rotation circle CR before the rotation of the tray 19, it is possible to achieve the height direction of the mechanical parking lot 1 (Z1, Z2 direction) miniaturization. -24 - 1361240 As described above, when the rotation processing of the tray 19 on which the vehicle 70 is loaded is completed, the control device 85 performs a process of transferring the vehicle 70 to the predetermined parking space 24. Assuming that the floor on which the vehicle 70 is parked is B2, the control unit 85 drives the lifting device 22 to lower the elevator frame 20 to a position where the tray 19 reaches the height position P3. Specifically, the control device 85 drives the lifting device 22 to lower the elevator frame 20, and after the first position detecting sensor 72 transmits the signal (P3 signal) that the notification tray 19 reaches the height position P3, the lifting device 22 is stopped. Thereby, the tray 19 on which the vehicle 70 is loaded is positioned at the height position P3. On the other hand, when the floor on which the vehicle 70 is parked is a floor other than B2, the control device 85 drives the lifting device 22 to lower the elevator frame 20 to the floor on which the vehicle 70 is parked. Then, when the vehicle 70 stops at B3, the visor 74 corresponding to B3 and the second position detecting sensor 73 (which can also be grasped by the first position detecting sensor 72) are engaged, and the notification tray 19 is reached at the height position. After the signal of P4 (P4 signal), control device 85 stops lifting device 22. Further, when the vehicle 70 is parked at B4, the visor 74 corresponding to B4 and the second position detecting sensor 73 (which can also be grasped by the first position detecting sensor 72) are engaged, and the notification tray 19 reaches the height. After the signal of the position P5 (P5 signal), the control device 85 stops the lifting device 22. At this time, the elevator frame 20 may be provided with a pulse encoder for generating a signal for ascending and descending with the elevator frame 2, together with the first or second position detecting sensors 72, 73, by the pulse. The encoder detects the approximate position of the elevator frame 20 (tray 19), and performs the configuration of the final stop position detection by the first or second position detecting sensors 72, 73. As described above, the tray 19 stops at the vehicle. After the predetermined floor for parking 70, the -25-1361240 control device 85 drives the first tray transfer device 21 provided in the elevator frame 20 and the second tray transfer device 45 provided in the parking space 24A (or the parking space 24B). The tray 19 (vehicle 70) mounted on the elevator frame 20 is transferred to the parking space 24A (or the parking space 24B). Next, the control device 85 drives the first and second tray transfer devices 21 and 45. The tray 19 on which the vehicle 7 is loaded is transferred to the predetermined parking space 24, and the empty tray 19 existing in the vehicle rack 12 is transferred to the first tray transfer device 2 on the elevator frame 20 1 After the transfer process of the tray 19 to the first tray transfer device 21 is completed, the control device The empty tray 19 is raised toward the height position P2 by driving the lifting device 22, and stops at this height. Next, the control device 85 drives the rotating device 23 to rotate the empty tray 19 by 180 degrees. Thereby, the empty tray 19 becomes a direction corresponding to the storage of the vehicle 70 (hereinafter, this rotation processing is an empty tray rotation process). Next, the control unit 85 drives the lifting device 22 again to raise the elevator frame 20 until the tray 19 becomes the height position P1. The warehousing process of the vehicle 70 is ended by performing the above processing. Next, the operation of the mechanical parking lot 1 at the time of departure of the vehicle 70 will be described together with the control operation performed by the control device 85. When the vehicle 70 is taken out of the mechanical parking lot 10, the storage operation is performed by an operation panel (not shown) disposed outside the passenger-elevating chamber 29. The state before the stocking operation is the state in which the empty tray 19 is located in the boarding and landing chamber 29, that is, the state at the height position P1 is stopped. When the library signal is transmitted from the operation panel, the control unit 85 lowers the tray 19 (empty tray 19) mounted on the elevator frame 20 to the floor where the vehicle -26-1361240 having the delivery instruction 70 is parked. In the following description, the vehicle 70 placed on the parking space 24 of the vehicle rack 12 of the B4 will be described as having an exit instruction. When the control unit 85 determines that the tray Γ 9 has reached the height position P2 as the elevator frame 20 is lowered by the P2 signal from the first position detecting sensor 72, the elevator frame 20 is stopped from being lowered. In the present embodiment, since the standard tray is used as the tray 19, the rotating device 23 is driven at the height position P2 and the empty tray 19 is rotated by 180°. φ In addition, the tray 19 is symmetrical with respect to the front and rear direction of the tray 19. When the reversible tray provided with the stoppers 19a and 19b is placed, since the directionality of the tray 19 in the front-rear direction is not required, it is not necessary to implement The above empty tray is rotated. Therefore, the time required for the empty tray rotation processing can be shortened, and the smoothness of the entry and exit can be improved, and power saving can be achieved. After the empty tray rotation processing is completed, the control device 85 drives the lifting device 22 again to lower the elevator frame 20. Then, after the P5 signal is transmitted by the second position detecting sensor 73 (which can also be detected by the first position detecting sensor 72), the control unit 85 stops the lifting device 22. Thereby, the empty tray 19 becomes in a state of being positioned at the height position P 5 . Next, the control device 85 appropriately performs the transfer processing of the tray 19 after considering the state of the vehicle 70 of the current vehicle rack 12, and transfers the tray 19 on which the vehicle 70 to be shipped is loaded, for example, to the parking space 24A, and The tray 19 of the parking space 24B is transferred to the other parking space 24. Next, the control device 85 first transfers the empty tray 19 mounted on the first tray transfer device 21 to the parking space 24B of B4 by driving the first tray transfer device 21 and the second tray transfer device 45. Next, the tray 19 on which the vehicle 70 (hereinafter referred to as the delivery vehicle 70) to which the -27-1361240 is to be taken out is loaded is transferred from the parking space 24A to the first tray transfer device 21. After the tray 19 on which the delivery vehicle 70 is loaded is transferred to the first tray transfer device 21, the control device 85 drives the lifting device 22 to raise the elevator frame 2 to the tray 19 to reach the height position Pi. The control device 85 confirms that the tray 19 on which the unloading vehicle 70 is stowed is raised to the height position P1 by the P 1 signal ' from the second position detecting sensor 73 (which can also be detected by the first position detecting sensor 7 2 ) After the situation, open the gate 2 7 . The driver sits in and out of the vehicle 70, causing the delivery vehicle 70 to advance from the tray 19 to exit from the boarding and landing room 29. Then, the driver closes the grill gate 27 by operating the operation panel. By performing the above processing, the delivery processing of the delivery vehicle 70 is completed. Further, when the warehousing is carried out, the tray 19 is lowered to the height position P2 and rotated, and then it is necessary (when the tray 19 is a reversible tray, the empty tray rotation processing is not required) to perform the process of raising it to the height position P1 (empty tray) Rotation processing). In the present embodiment, the vehicle 70 is rotated by 180° at the height position P2 in the elevator hoistway 14 at the time of storage. Therefore, the front of the delivery vehicle 70 is facing the side of the grille door 27 at the time of delivery, whereby the vehicle 70 can be taken up and down. The room 29 can be improved by the advancement, and the convenience of the driver can be improved. The preferred embodiment of the present invention has been described in detail above. However, the present invention is not limited to the above specific embodiment, but is patented. Various modifications and changes can be made without departing from the spirit and scope of the invention. Specifically, in the present embodiment, an example in which the present invention is applied to a three-dimensional parking lot in which the vehicle rack 12 is B 2 to B4 has been described. However, the case of only one layer of the -28-1361240 vehicle rack 12 can be applied. this invention. Further, in the present embodiment, the tray 19 is rotated only by the elevator lifting path I4 at the height position P2 of the B2. However, the tray 19 may be configured to be rotatable on any of the floors B3 and B4. However, in the case where the configuration is set, the structure of the B3 and B4 is larger than δη in height (the height in the Z1 and Z2 directions), and the mechanical parking lot 1大型 is increased in size. Therefore, the above embodiment has a large advantage. In the above-described embodiment, the first tray transfer device 21 and the second tray transfer device 45 are shown as an example of the transfer device disclosed in Japanese Patent Publication No. Hei 7-2968, but the first tray is transferred. The device 21 and the second tray transfer device 45 are not limited thereto, and any other transfer device may be used as long as the rotatable tray 19 is configured.
