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

  FIG. 1 is a side view showing a schematic configuration of a multi-storey tray type parking apparatus.

  In this multi-storey tray type parking apparatus, a parking vehicle entrance / exit 1 is provided on the first floor of a building, and a storage space for storing a parked vehicle is formed above. A plurality of guide rails 2 are arranged between the entrance / exit 1 and the storage space, and the elevator 3 that moves up and down along these guide rails 2 and the elevator 3 that is arranged in the lower pit. A driving device 4 for driving, a turntable 6 for changing the direction with the parked vehicle 5 mounted, and a turntable driving device 7 for lowering the turntable 6 after changing the direction of the parked vehicle 5 by the turntable 6; A lift device having a tray 8 or the like in which the parked vehicle 5 is mounted by lowering the turntable 6 by the turntable driving device 7 is configured.

  In the upper part of the lift device and the turntable 6, a building space is formed upward, and a support structure 9 for forming a multistage floor is constructed in the building space. By this support structure 9, a hoistway 10 is formed in the elevating direction of the elevating platform 3, and storage spaces 11 and 12 are formed on both sides of the hoistway 10. Here, the support structure 9 is not provided with a fixed floor for dividing the storage spaces 11 and 12 in the vertical direction.

  As shown in the drawing, the parked vehicle 5 entering from the entrance / exit 1 is stopped on the turntable 6 and when the turntable driving device 7 is operated, the turntable 6 turns 90 degrees on the horizontal plane and changes its direction. Then, the parked vehicle 5 is mounted on the tray 8 previously arranged on the lifting platform 3 by lowering the turntable 6 by a predetermined distance. Thereafter, the lifting platform 3 is driven to move up the hoistway 10 along the guide rail 2 in accordance with a program predetermined by a control device that will be described in detail, and is moved to a predetermined height position. Thereafter, the tray 8 on which the parked vehicle 5 is mounted is stored in the storage space 11 or the storage space 12 by a delivery device whose details are omitted. For example, the tray 8A on which the parked vehicle 5A is mounted is stored as it is in the storage space 11 as it is.

  This multi-storey type tray parking system does not use a fixed tray storage floor with a parked vehicle mounted, as in the past, and the entire parking space is used for high-roof vehicles with high vehicle heights and other ordinary vehicles. It will not be completely separated from cars. This multi-storey tray type parking device divides a parked vehicle into a plurality of vehicles according to the height of the vehicle so that it can respond flexibly depending on the situation of the parked vehicle for high roof vehicles and other ordinary vehicles. . However, in order to simplify the description, an example in which a parked vehicle is divided into a high roof vehicle and a normal vehicle according to the vehicle height will be described below.

  FIG. 5 is an enlarged view showing the vicinity of the entrance / exit 1 which is a main part of FIG. 1, and a configuration for distinguishing whether the parked vehicle is a high roof vehicle or a normal vehicle will be described.

  In the vicinity of the entrance / exit 1 is a vehicle type declaration button 13 for declaring whether the vehicle that the driver drives at the time of warehousing is a high roof vehicle or other ordinary vehicles, and a normal vehicle having a vehicle height of a high roof vehicle or lower when entering for parking. A photoelectric tube type vehicle height determination device 14 for determining whether or not Here, when the vehicle type declaration button 13 is operated, it is treated as a warehousing signal, and the vehicle type declaration button 13 and the photoelectric tube type vehicle height determination device 14 are handled as vehicle height determination signals. The phototube type vehicle height determination device 14 may be provided with only a pair of phototubes at a height determined as a high roof vehicle when light is shielded, or a plurality of pairs of phototubes are arranged at substantially the same height to improve reliability. Various configurations can be adopted, such as arranging a plurality of pairs of phototubes having different heights so that they can be detected while distinguishing between a high roof vehicle and other vehicles, or using sensors other than phototubes.

  FIG. 2 is an enlarged front view of the main part of the multi-storey tray type parking apparatus shown in FIG. 1, and shows the storage space 11 from the hoistway 10 side. The parked vehicle can be a high roof car or a normal car. The structure which can be stored is shown.

  The support structure 9 described above can employ various configurations, but when storing a tray with a parked vehicle mounted on the storage space 11 side from the hoistway 10 side, columnar shapes located on both sides of the frontage. Members 15 and 16 are provided. The distance between the columnar members 15 and 16 is selected so as not to interfere when the tray is put in and out. Although not shown in the figure, columnar members are arranged on the back side of the frontage with a similar interval. Since the storage space 12 side has the same configuration, only the storage space 11 side will be described here.

  A plurality of tray guide members 17 </ b> A to 17 </ b> M arranged at a predetermined interval in the vertical direction are fixed to the columnar members 15 arranged on the front side and the back side on the left side of the frontage. On the other hand, on the right side of the frontage when viewed from the hoistway side, a plurality of tray guide members 18 </ b> A to 18 </ b> M arranged at predetermined intervals in the vertical direction are provided on the columnar members 16 arranged on the near side and the far side, respectively. Is fixed. The tray guide members 17A to 17M and the tray guide members 18A to 18M are adjusted in the vertical direction so as to form a pair. For example, the tray guide member 17A and the tray guide member 18A have the same level. Is placed on top.

Among the tray guide members 17A~17M and the tray guide member 18A～18M, those located on each the same horizontal plane, for example, a tray guide member 17A, 18A can lift the tray 8 A state equipped with parked vehicle path 10 mounted by receiving from the side, will want to hold a storage state, the tray guide member 17A, the inter-18A, and has a face distance is received an end portion of the tray 8 a simultaneously. The tray 7A placed on the lifting platform 3 is fed to the tray guide members 17A and 18A by the feeding device configured on the lifting platform 3, but a detailed description of the feeding device is omitted here.

  Next, the step intervals in the vertical direction of the tray guide members 17A to 17M and 18A to 18M will be described.

  Here, the vertical step interval of each tray guide member is necessary for a normal vehicle as a parked vehicle so that the storage position of the normal vehicle and the high roof vehicle can be dealt with according to the situation without predetermining the storage position. It is smaller than both the vertical height dimension and the vertical height dimension required for the high roof car as the parked vehicle. More specifically, the step interval is set to 450 mm. If it is arranged at an interval of 450 mm in the vertical direction, four stages, that is, 1800 mm can be used for mounting a normal vehicle on the tray. On the other hand, when a high roof car is mounted on the tray, five stages, that is, 2250 mm can be used.

The leftmost arrow A1, A2, A3 in FIG. 2, successively a tray mounted state an ordinary vehicle from below shows the case of storing upward, because the ends of the lowermost tray 8 A a pair of tray guide members 17A uses 18A, a pair of tray guide members 17E are for tray 8 B of the second stage, using 18E, a pair of trays for tray 8 C of the third stage The state where the guide members 17I and 18I are used is shown in a simplified manner.

  The second arrows A4 and B1 from the left indicate a case where a tray with a normal vehicle and a tray with a high roof vehicle are mixed and stored. For the lowermost tray, a pair of trays are shown. The guide members 17A and 18A are used, and a state where a pair of tray guide members 17F and 18F are used for the second tray is shown in a simplified manner.

  Further, the third arrows B2 and A5 from the left indicate a case where a tray with a high roof car and a tray with a normal car are mixed and stored. For the bottom tray, a pair of trays are used. The guide members 14A and 15A are used, and a state where a pair of tray guide members 17F and 18F are used for the second tray is shown in a simplified manner.

  Further, the rightmost arrows B3 and B4 indicate the case where the trays on which the high roof cars are mounted are continuously stored from below, and a pair of tray guide members 17A and 18A are used for the lowermost tray. For the second tray, a state in which a pair of tray guide members 17F and 18F are used is shown in a simplified manner.

  FIG. 3 is a block diagram showing a control device of the multi-stage tray type parking device.

  The control device includes a signal receiving unit 20 that captures the warehousing signal and the vehicle height signal from the vehicle type declaration button 13 and the phototube type vehicle height determining device 14 shown in FIG. The warehousing signal taken in by 20 and the warehousing management unit 21 that gives a series of corresponding operation commands when taken in as a warehousing signal, and the lift driving unit 22 that drives the lift device in response to a signal from the warehousing / managing management unit 21. And have.

  In addition to the above-described configuration, the control device captures the vehicle height signal captured by the signal receiving unit 20 as a high roof signal or a normal vehicle signal, and sets the vertical position of the tray guide members 17A to 17M and 18A to 18M serving as storage positions. The storage space management unit 23 that manages the location information and the storage management unit 21 obtains the location information from the storage space management unit 23 when there is no warehousing and exiting processing and the predetermined timing is reached. The remaining space management unit 24 that performs the calculation process and the remaining space management unit 24 can store the parked vehicle by collecting the remaining space in the lift driving unit 23 when the total of the remaining space in the vertical direction exceeds a predetermined value. An empty space forming tray driving unit 25 for performing an empty space forming processing operation so as to form an empty space; The storage unit 26 which stores a program, and a control unit 27 for controlling each section in accordance with the processing program.

  As in the normal configuration, when receiving a warehousing signal from the warehousing / unloading management unit 21, the lift driving unit 22 drives the turntable when the parked vehicle is stopped on the turntable 6 shown in FIGS. The device 7 is driven and the turntable 6 turns 90 degrees on the horizontal plane and changes its direction. After that, the turntable 6 is lowered by a predetermined distance, so that it is parked on the tray 8 arranged in advance on the lifting platform 3. The vehicle 5 is mounted. Thereafter, the lift drive unit 22 drives the elevator 3 up along the guide rails 2 of the hoistway 10 and moves the tray 8 in a state where the parked vehicle 5 is mounted after moving to a predetermined height position. It is stored in the storage space 11.

  On the other hand, when receiving a delivery signal from the entry / exit management unit 21, the lift drive unit 22 drives the elevator 3 to a position corresponding to the delivery vehicle, and feeds the tray 8 with the parked vehicle 5 mounted thereon by a feeder. It is taken out from the storage space 11 and mounted on the lifting platform 3 to perform the reverse operation to that at the time of warehousing.

  Furthermore, when receiving the warehousing signal or the warehousing signal, the warehousing / exiting management unit 21 newly performs a process of determining the stop position of the lifting platform 3 using the position information from the storage space management unit 23 in addition to the normal operation. And the lift drive unit 22 is controlled on the basis thereof. In addition to the normal configuration, the lift drive unit 23 reflects the stop position from the storage management unit 21 and performs an empty space formation processing operation when receiving a signal from the empty space formation tray drive unit 25. The drive of the lift device is newly controlled.

  FIG. 4 is a flowchart showing a main part of the processing operation of the control device shown in FIG.

  First, it is determined in step S1 whether or not the vehicle is full. If the vehicle is not full, a warehousing indication is displayed in step S2, and a warehousing signal wait state is entered in step S3. Here, it is assumed that the parked vehicle is an ordinary vehicle and the ordinary vehicle side of the vehicle type declaration button 13 shown in FIG. This also becomes a warehousing signal and is transmitted to the warehousing management unit 21 as a warehousing signal for a normal vehicle, and the warehousing management unit 21 waits for a signal from the storage space management unit 23.

  Subsequently, the storage space management unit 23 determines that the vehicle is received as a vehicle height signal when the signal of the vehicle type declaration button 13 matches the detection by the phototube type vehicle height discriminating device 14 in step S4, and four steps in step S5. The used area is calculated, and the area is registered as being used. Thereafter, the storage space management unit 23 transmits the position data to the incoming vehicle management unit 21.

  Upon receipt of this signal, the warehousing management unit 21 provides the lift driving unit 22 with position data, in particular, position data on which a tray with a parked vehicle is mounted. In step S6, the lift drive unit 22 drives the lift device to drive the lifting platform 3 to a position corresponding to the position data, and then, for example, places the tray 7A on the tray guide members 17A and 18A as indicated by an arrow A4 in FIG. Store.

  On the other hand, if it is determined in step S4 that the warehousing vehicle is a high roof car, a five-step use area is calculated in step S7, and the area is registered as in use. Thereafter, the storage space management unit 23 transmits the position data to the incoming vehicle management unit 21. Upon receipt of this signal, the warehousing management unit 21 gives the lift driving unit 22 position data for placing the tray with the parked vehicle mounted thereon. In step S6, the lift drive unit 22 drives the lift device to drive the lifting platform 3 to a position corresponding to the position data, and then, for example, places the tray 7A on the tray guide members 17E and 18E as indicated by an arrow B1 in FIG. Store.

  The management state in the storage space management unit 23 when a plurality of parked vehicles are stored in this manner is schematically shown in FIG.

  The storage space management unit 23 stores the entry time 28 and the exit time 29 for each entry or exit, and manages the type 30 on the basis of the vehicle height signal from the vehicle type declaration button 13 and the vehicle height determination device 14. . In type 30, a high roof car is indicated by “H”, and a normal car is indicated by “R”. The position information 31 is displayed as “11” when stored in the storage space 11 shown in FIG. 1 and is displayed as “12” when stored in the storage space 12.

  The use area 32 indicates that the four-stage area from the lowermost tray guide members 17A and 18A to the fourth tray guide members 17E and 18E is used for the normal vehicle of the number “1”. Yes. On the other hand, for the high roof car of the number “2”, the five-step region from the uppermost tray guide members 17E, 18E to the fourth tray guide members 17J, 18J in the use region of the number “1”. Indicates that you are using. The stop position 33 indicates storage position data of the tray on which the parked vehicle is mounted. The tray on which the normal vehicle with the number “1” is mounted is in the tray guide members 17A and 18A, and the high roof vehicle with the number “2” is mounted. This shows that the trays are on the tray guide members 17E and 18E. This corresponds to the storing method indicated by arrows A4 and B1 in FIG.

  According to such a multi-stage tray type parking apparatus, it is possible to park a common car and a high roof car between a plurality of tray guide members 17A to 17M and 18A to 18M arranged in a distributed manner in the vertical direction. It becomes. If a fixed floor is used and the space for exclusive use of the high roof car and the space for exclusive use of the normal car are configured on different floors as before, the space for exclusive use of the high roof car will be used when there is an imbalance in the number of parked vehicles. Even if a normal car can be parked, the inconvenience that a high roof car cannot be parked in a space dedicated to a normal car will arise, resulting in a situation where the storage rate cannot be improved. Generation | occurrence | production can be prevented and a storage rate can be raised.

  Moreover, the step interval is smaller than both the vertical height required for a normal vehicle as a parked vehicle and the vertical height required for a high roof vehicle as a parked vehicle. As compared with the case where the whole has a step interval that can be used for a high roof vehicle, it is possible to prevent the generation of useless space and perform efficient storage.

  It is desirable that the above-described pair of tray guide members in the vertical direction have a step distance of 450 mm or similar dimensions, but the present invention is not limited to this and can be employed. For example, the vertical height dimension required to store a normal car and the vertical height dimension required to store a high roof car are determined, and their greatest common divisor or a dimension approximating them is determined. It is desirable that the pair of tray guide members have a step interval in the vertical direction. Further, when the height dimensions of the storage spaces 10 and 11 are determined by the building space, the vertical step interval between the tray guide members that form a pair is the vertical height dimension required for storing a normal vehicle. When the common multiple of the vertical height required for storing the high roof vehicle is used, the space can be utilized more efficiently.

  Therefore, in any case, a plurality of tray guide members that are paired at a step height of about 1800 mm are arranged in the vertical direction required for storing a normal vehicle, and the tray guide members A tray guide member that forms another pair for adjustment may be provided in an intermediate portion in the vertical direction. That is, with reference to FIG. 2, tray guide members 17A, 17E, 17I that are paired at intervals of the vertical height dimension required for storing a normal vehicle are arranged, and the upper and lower sides of these tray guide members are arranged. It is preferable to provide at least one of tray guide members 17F to 17H forming another pair for adjustment at an intermediate portion in the direction.

  For example, if the adjustment is for the tray guide member 17F, only a normal vehicle can be stored between the tray guide member 17A and the tray guide member 17E, but a high roof vehicle can also be stored. The adjustment is the same for the tray guide members 17G and 17H. However, when the adjustment is the tray guide member 17H, when the high roof car is stored, the remaining space formed in the upper part thereof is larger than that in the case of the tray guide member 17F. High roof cars can be stored.

  By the way, in FIG. 6, the parked vehicle with the number “2” has been issued at “10:30”. Subsequently, when the same high roof car is received, it can be stored in the use area 32 of the same number “2”. However, if it is almost full, and the normal car is subsequently stored in the use area 32 of the same number “2”, the use area of the high roof car is five levels while the use of the normal car is used. Since the area is four steps, a remaining space is generated between the tray guide members 17I and 18I and the tray guide members 17J and 18J.

This will be described with reference to FIG. The high roof car is stored in the area indicated by the arrow B1, but it is assumed that the ordinary car indicated by the arrow A1 is stored using the empty space generated after the delivery. Also in this case, the tray 8B mounted with the ordinary vehicle indicated by the arrow A1 is placed and stored on the tray guide members 17E and 18E. However, since the tray 8C on which the parked vehicle stored immediately above is mounted is placed between the tray guide members 17J and 18J, a remaining space indicated by the arrow H1 is generated. If this remaining space occurs only at one location, it can be ignored, but if the same situation occurs at multiple locations in the vertical direction, the overall useless space increases and the storage rate is affected. End up.

  Therefore, the remaining space management unit 24 shown in FIG. 3 performs the following process at a preset time and at a predetermined timing when the lift device is not operating. Here, as shown in FIG. 4, the predetermined timing for performing the processing operation is shown when the vehicle is full, but the present invention is not limited to this.

  When it is determined that the vehicle is full in step S1, the remaining space management unit 24 performs an empty space calculation process in step S9 after displaying the full vehicle state in step S8. This uses the data in the storage space management unit 23 to extract all the spaces such as the remaining space H1 described in FIG. Thereafter, the remaining space management unit 24 accumulates the remaining spaces in step S10 and determines whether or not a predetermined value has been reached. As a result of the determination, if there is a space for four steps corresponding to an area that can be allocated to a normal vehicle, the remaining space management unit 24 aggregates the plurality of remaining spaces distributed in step S11 into one place. In order to cause the lift device to perform a series of operations for changing the position of the already stored tray, a program is created or extracted by the empty space forming tray driving unit 25 and lift driving is performed from the empty space forming tray driving unit 25. The lift device is driven through the section 22.

  A new empty space that can further store one ordinary vehicle can be formed by the moving process of consolidating the plurality of remaining remaining spaces into one place. Therefore, the remaining space that may be generated by mixing the normal car and the high roof car in the vertical direction is collected, and more efficient parking becomes possible.

  FIG. 8 is a front view showing a main part of a multi-storey tray type parking apparatus according to another embodiment of the present invention.

  In the previous embodiment, the tray guide members 17A to 17M and 18A to 18M are arranged at equal intervals in the entire vertical direction of the storage spaces 11 and 12, but in this embodiment, the tray guide member 17B at a position that is not used. ˜17D, 17G, 18B to 18D, 18G are omitted. A similar effect can be obtained by such a configuration.

  FIG. 9 is a side view showing a schematic configuration of a multi-storey tray type parking apparatus according to still another embodiment of the present invention.

  In the previous embodiment, the tray guide members 17A to 17M and 18A to 18M are arranged at equal intervals in the entire vertical direction of the storage spaces 11 and 12, but in this embodiment, the vertical direction of the storage spaces 11 and 12 is arranged. Is divided into a plurality of areas 34, 35 and 36, and only ordinary cars are stored in the area 34, and the floor is fixed as in the prior art. Further, only the high roof car is stored in the area 36, and the floor is fixed as in the prior art. On the other hand, the area 35 is configured to store a standard vehicle and a high roof vehicle in a mixed manner, and the floor guide members 17A to 17M and 18A are selectively used as shown in FIGS. It is set to ~ 18M.

  According to such a configuration, when the ordinary car is a parked vehicle, it is stored in the dedicated area 34, and when the high roof car is a parked vehicle, it is stored in the dedicated area 36, and one of them is almost full. In this case, for example, when the high roof vehicle in the region 36 is almost full, the high roof vehicle can be stored from the region 34 side of the region 35.

  In addition, the multi-storey tray type parking apparatus having the storage spaces 11 and 12 on both sides of the hoistway 10 has been described. However, only one of the storage spaces is stored with a mixture of ordinary vehicles and high roof vehicles. In addition, as shown in FIGS. 2 and 3, the floor can have the same effect even if the tray guide members 17 </ b> A to 17 </ b> M and 18 </ b> A to 18 </ b> M are selectively used. Furthermore, the present invention can also be applied to a multi-storey tray type parking apparatus in which a storage space is formed by being distributed in the upper part and the basement side, or a storage space is formed only on the basement side.
