Description

  The present invention relates to a simultaneous elevator parking apparatus. More specifically, a simultaneous elevator type in which a plurality of elevator parking devices in which parking sections such as parking shelves for storing a vehicle are formed in a plurality of upper and lower stages along the hoistway of the elevator for raising and lowering the vehicle are arranged in close proximity. It relates to parking equipment.

  An elevator parking device (hereinafter also simply referred to as a parking device) generally includes a parking tower and an elevator that lifts and conveys a vehicle disposed inside the parking tower. Inside the parking tower, parking shelves are arranged on both sides of the elevator hoistway, on which pallets for vehicle mounting can be placed in a plurality of stages. The elevator raises and lowers the pallet between the parking tower entrance / exit floor and the arbitrarily designated parking rack to convey the vehicle M.

  2. Description of the Related Art Conventionally, a so-called simultaneous self-propelled elevator parking device in which two such parking devices (a parking tower) are connected is known. The self-propelled type here refers to a system in which a warehousing vehicle enters by itself from a loading / unloading port and moves to a predetermined parking tower. Such a simultaneous elevator type parking apparatus is a parallel parking apparatus in which two parking towers are connected in a direction along the vehicle placement direction of the parking rack and in the direction of loading / unloading of the vehicle (for example, , See Patent Document 1 and Patent Document 2). Here, the parking tower with the entrance / exit is called the parking tower on the entrance side, and the other parking tower is called the parking tower on the back side.

  In these parking apparatuses, two simultaneous parking towers each have one elevator. Moreover, the loading / unloading direction of the vehicle passing through the loading / unloading port is a direction perpendicular to the longitudinal direction of the elevator and the parking rack. In other words, the entrance / exit and the passage opening between the two parking towers are formed at such a position as to be in the entry / exit direction. Therefore, the elevator landing position on the entry / exit floor is provided with a turntable for turning the entering / exiting vehicle 90 °. Usually, such a parking device is called a 90 ° -in type parking device. The turntables in Patent Document 1 and Patent Document 2 are installed in a pit dug in the floor surface. In such a parking device, when a vehicle entering / exiting the parking tower on the back side passes through the entrance / exit floor, it is necessary to block the pits on the entrance / exit floor to form a roadway.

  As such a road formation method, in the parking device of Patent Document 1, the elevator of the entrance side parking tower is lowered without placing a pallet and is positioned on the pit upper surface of the entry / exit floor, and further, the upper surface of the turntable. To match the top of the pit. By doing so, the upper surface of the elevator and the upper surface of the turntable are made to coincide with the vehicle traveling floor surface of the loading / unloading floor, and the pit is closed to form a roadway.

  In addition, shallow recesses C are formed on the entrance / exit floors of both parking towers so that the longitudinal direction of the pallet is placed in the entry / exit direction when the vehicle is in / out. Therefore, when the vehicle enters or leaves the entrance-side parking tower, the pallet is lowered to the upper surface of the turntable on the entry / exit floor by the elevator. The pallet is raised slightly by the turntable and then turned 90 ° to place the pallet in the recess C. In this way, the vehicle can enter or exit the pallet. This is because when the pallet is fitted into the shallow recess C, the vehicle placement surface of the pallet is flush with the vehicle traveling floor surface of the entry / exit floor.

  As described above, in the parking device of Patent Document 1, it is necessary to lower the elevator to the entrance / exit floor in order to form a roadway in the entrance side parking tower, and it takes too much time to enter and exit the back side parking tower. Moreover, the pallet which has a traverse rail and a traverse wheel on the lower surface cannot be employ | adopted.

  On the other hand, in the parking apparatus of patent document 2, since each pallet is provided with the rail for traversing on the lower surface, the different method is employ | adopted. First, when closing the pit of the entrance side parking tower to form a roadway, the elevator of the entrance side parking tower is lowered without placing a pallet and positioned on the pit upper surface of the entry / exit floor. At this time, as will be described later, in order to drop the traverse rail of the pallet, a pit portion that cannot be closed by the elevator is provided. This part is called a groove part. The groove is closed by a movable deck that is elastically biased upward. The movable deck and the elevator block the pit and form a roadway.

  Also, when the vehicle enters or exits the entrance side parking tower, the pallet is lowered to the entry / exit floor by the elevator, slightly raised by the turntable, and then turned 90 ° to turn the pallet The longitudinal direction is directed to the entry / exit direction. Then, when the pallet is lowered a little in this state, the pallet is placed on the upper surface of the elevator and the vehicle traveling floor surface of the loading / unloading floor. At this time, the transverse rail on the lower surface of the pallet fits into the groove while pushing down the movable deck. By this fitting, the level difference between the vehicle placement surface of the pallet and the vehicle traveling floor surface of the loading / unloading floor caused by the traverse rail is eliminated, and the vehicle can enter the pallet or get out of the pallet.

  As described above, in the parking device of Patent Document 2, it is necessary to lower the elevator to the entrance / exit floor in order to form a roadway in the entrance side parking tower, and it takes too much time to enter and exit the back side parking tower. Further, in order to prevent the tire from being damaged when the vehicle passes, it is necessary to prevent the wheel from being pushed into the movable deck and fitted into the groove. That is, the width of the groove portion must be reduced, but this is difficult.

This is because when the pallet is turned, there are variations in the turning stop position (stopping position of the transverse rail and the transverse wheel), the assembly error of the transverse rail and the transverse wheel assembled on the lower surface of the pallet, and the like. In order to absorb these, the width of the groove must be considerably large.

  An embodiment of a simultaneous elevator parking apparatus (hereinafter simply referred to as a parking apparatus) of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a longitudinal sectional view schematically showing an embodiment of a parking apparatus of the present invention. FIG. 2 is a plan view (a view taken along the line II-II in FIG. 1) showing the entry / exit floor of the parking apparatus of FIG. 3 is a plan view (a view taken along the line III-III in FIG. 1) showing the parking floor of the parking apparatus in FIG.

  In the parking apparatus 1 shown in FIG. 1, two parking towers 2 and 3 having the same shape are installed in a state of being adjacent to each other. Of course, the parking tower is not limited to two but may be three or more. The entrance / exit 20 is formed in the ground floor of the 1st parking tower (it is also called entrance side parking tower) 2 of the left side in the figure. The wall surface on which the entrance / exit 20 is formed is a wall surface on the opposite side to the adjacent second parking tower (also referred to as the back parking tower) 3 on the right side. On the ground floor, a vehicle passage opening 22 and a vehicle passage opening 22 are formed in the boundary wall 21 between the first parking tower 2 and the second parking tower 3. An operation panel 38 and a control device 39 connected to the operation panel 38 are disposed outside the loading / unloading port 20.

  A first elevator 4 is installed in the first parking tower 2, and a second elevator 5 is installed in the second parking tower 3. The elevators 4 and 5 raise and lower the vehicle M to store and unload the vehicle. The elevators 4 and 5 are moved up and down by a drive device (also referred to as a hoisting device) 6 and a balance weight 7 when a wire (or chain) 8 as a hoisting rope is wound up and fed out.

  The longitudinal directions of both elevators 4 and 5 are oriented in the direction of 90 ° in the direction in which the vehicle M entering from the entrance / exit 20 travels straight. The elevators 4 and 5 ascend and descend the hoistways 9 and 10 in the center of each parking tower in plan view. On both sides of each hoistway 9, 10, parking shelves 11 that form a parking section of upper and lower floors are arranged. All the parking racks 11 are installed such that the longitudinal direction thereof is parallel to the longitudinal direction of the elevators 4 and 5. This type of elevator parking system is called a 90 ° boarding type.

  In the parking apparatus 1, a pallet 12 for mounting on a vehicle is placed on each parking shelf 11. The elevators 4 and 5 move up and down between the parking racks 11 on both sides, move to the designated parking rack 11 floor, and then deliver the pallet 12. At the time of delivery, the vehicle M is transported to the entry / exit floor E. In the parking apparatus 1, the entry / exit floor E is the lowermost floor (first floor) of each parking tower 2, 3. Rails 35 (see FIG. 4) for pallet traversing are laid on the upper surfaces of the elevators 4 and 5 and the parking rack 11. A traverse wheel 25 that rolls on the traverse rail 35 is attached to the lower surface of the pallet 12. As shown in FIG. 4, a traverse rail may be attached to the lower surface of the pallet 12, and guide roller rows for guiding the movement of the traverse rail may be installed on the upper surfaces of the elevators 4, 5 and the parking rack 11.

  As shown in FIGS. 1 and 3, each elevator 4, 5 has a turning device 13 for turning the pallet 12 in a horizontal plane, and a lateral feed device 14 for delivering the pallet 12 between the parking rack 11. Are arranged. The lateral feed device 14 has a carriage 16 that can move a predetermined distance on both sides in the width direction at the center of the frame of each of the elevators 4 and 5, and a base end portion of the carriage 16 that pivots around the center of the carriage 16. The crank arm 17 is provided with a drive device (not shown) that performs the transverse drive of the carriage 16 and the turning point drive of the crank arm 17. An engagement pin 18 projects upward from the tip of the crank arm 17. On the other hand, an engaged groove 23 (see FIG. 4) for engaging with the engaging pin 18 is formed at the edge of the pallet 14 facing the hoistway so as to open downward. By rotating the crank arm 17 while traversing the carriage 16, the engagement pin 18 is engaged with the engaged groove. The pallet 14 is traversed by traversing the carriage 16 in the direction opposite to the above while rotating the crank arm 17 as it is.

  On the entry / exit floor E, a pit P is formed into which the elevators 4 and 5 equipped with the turning device 13 and the lateral feed device 14 enter. In the pit P of the entrance side parking tower 2, an elevating floor 15 having a flat upper surface is accommodated so as to be movable up and down. The elevating floor 15 has a rectangular shape in plan view that is substantially the same as that of the pallet 12, and the pits also have a similar shape. A slight clearance is formed between the periphery of the lift floor 15 and the inner surface of the pit. As will be described later, the elevator floor 15 is used to slightly lift the pallet when the first elevator 4 reaches the entry / exit floor E and reaches the upper surface of the elevator floor 15 and turns the pallet. Furthermore, when the entering / exiting vehicle M moves between the entering / exiting entrance 20 and the side parking tower 3, it is used to form a roadway.

  Therefore, in this embodiment, the position at which the elevating floor 15 stops is the lowest position (first lowered position) for the elevator 4 to ride and slightly above the lowest position for turning the pallet (substantially the pallet traversing). The wheel height dimension) is the pallet turning position (second descending position) and the uppermost position (upward position) where the upper surface coincides with the vehicle traveling floor surface of the entry / exit floor to form the roadway . Of course, it is possible to stop at a position other than the three positions as required. The elevator 4 is mounted integrally with the swivel device 13 on the lifting floor 15 at the lowest position, but when the pallet is swung, the elevator 4 is locked and moved without moving due to the lift of the lifting floor 15 to the pallet swiveling position. Only the device 13 is raised slightly. For this reason, the elevator 4 and the turning device 13 are configured to be relatively displaced up and down by a certain size.

  As will be described later, when the entry vehicle M moves from the entrance / exit 20 to the back side parking tower 3 and when the exit vehicle M moves from the back side parking tower 3 to the entrance / exit 20, the entrance side parking tower 2 Then, the elevating floor 15 in the pit rises to a position where the upper surface thereof coincides with the vehicle traveling floor surface of the entry / exit floor E to form a roadway. At this time, the first elevator 4 is retracted upward.

  Various devices can be used as the lifting drive device for the lifting floor 15. For example, a so-called scissor-type X leg in which a plurality of bar members are assembled so as to be foldable and extendable, and a hydraulic cylinder for pushing up and lowering the bar member constituting the X leg may be used. The X leg and the hydraulic cylinder are preferably installed at the front and rear of the lift floor. First, one end of one bar member constituting the X leg is pivotally supported on the pit floor, and the other end is slidably attached to the lower surface of the lift floor. The other end is slidably attached to the pit floor in a horizontal direction. Specifically, the sliding in the horizontal direction is performed by a guide roller, which is attached to the tip of the bar member, being slidably engaged with a horizontal rail disposed on the lower surface of the pit floor and the lift floor. The cylinder base of the hydraulic cylinder pivots on the bottom of the pit, and the rod tip pivots on the other rod member.

  Of course, other lifting drive devices may be used. For example, a mechanism is installed in which pulleys are attached to the left and right ends of the elevator floor, and a chain or wire rope is hung on the pulley from the bottom, and the chain is wound up by a sprocket, a hoisting drum, etc. May be. In this case, it is desirable to attach a known balance chain mechanism for stable raising and lowering of the lifting floor. Further, hydraulic cylinders as jacks may be provided at the four corners of the lift floor instead of the chain drive. The lift floor is moved up and down by operating four hydraulic cylinders synchronously. Alternatively, instead of the hydraulic cylinder, ball screws as feed screw mechanisms may be installed at the four corners of the lift floor, and the lift floor may be raised and lowered by operating this feed screw mechanism in synchronization.

  There is no elevator floor installed in the pit P of the rear parking tower 3, and only the elevator 5 enters. This is because the vehicle does not pass through the entrance / exit floor of the back side parking tower 3, and therefore it is not necessary to form a roadway. The shape of the pit P in plan view is almost the same as that of the elevator 5. At the bottom of the pit P, a concrete platform T having the same height as the lift floor 15 of the entrance side parking tower 2 is formed. The elevator 5 reaching the entrance / exit floor of the back side parking tower 3 is on this concrete platform T. The floor surface around the pit P is slightly lower than the vehicle traveling surface so that the pallet does not interfere when the pallet is turned. Therefore, it is not necessary to slightly raise the turning device and the pallet when turning the pallet as in the prior art.

  However, as shown in FIGS. 1 and 2, the swing deck 45 is arranged from the vehicle passage opening 22 toward the floor surface of the rear parking tower 3. The swing deck 45 is configured as a floor plate member that can swing downward with one side of the vehicle passage opening 22 side as a fulcrum. The swing deck 45 is normally in a horizontal state, and its upper surface is flush with the vehicle placement surface of the pallet on the elevator 5. However, when the pallet turns, the side on the pit side swings downward to avoid interference with the pallet.

  As shown in FIG. 5 and FIG. 6, swing decks 24 are respectively disposed on the left and right sides of the pit P of the entrance side parking tower 2. The swing deck 24 swings downward when the first elevator 4 that has landed on the loading / unloading floor E turns the pallet 12 by 90 ° to land on the floor surface of the loading / unloading floor E. By dropping the 12 traverse wheels 25 (FIG. 5), the vehicle mounting surface of the pallet 12 and the vehicle traveling floor surface of the loading / unloading floor E are made to coincide. Therefore, when the lift floor 15 constitutes a roadway, the floor surface of the entry / exit floor E needs to be flat, so that the swing deck 24 is kept horizontal without swinging to form a roadway ( FIG. 6).

  FIGS. 7 and 8 show the structure of the swing deck 24 and the swing drive mechanism in detail, representing the left swing deck in FIGS. 5 and 6 in detail. 7 is a diagram corresponding to FIG. 5, and FIG. 8 is a diagram corresponding to FIG. Each swing deck 24 has a rectangular shape in plan view in order to close a rectangular recess 26 formed on the floor surface of the loading / unloading floor. In the present embodiment, the elevating floor 15 is configured to be swingable downward with its pit side portion as a fulcrum (pivot fulcrum). As shown in the drawing, the side serving as the swing fulcrum is separated from the pit P. However, the present invention is not limited to this configuration. The swing fulcrum of the swing deck 24 is located near one side of the pit P by increasing the deck width. It is good. The swing end of the swing deck 24 is required to lower at least the vertical dimension of the traversing wheel 25 of the pallet by swinging. Further, in the case where a traverse rail is attached to the lower surface of the pallet 12 instead of the traverse wheel 25, the swing deck needs to be configured to swing at least by a dimension for dropping the traverse rail. As shown in the figure, the swing drive mechanism is attached to a frame 40 assembled below the floorboard of the entry / exit floor E.

  As shown in the figure, a driven arm 27 as a swing member installed near the swing end of the swing deck 24, a drive arm 28 as an operation member installed near the inner wall of the pit P, A connecting rod 29 as a transmission member for connecting the drive arm 28 is provided. The drive arm 28 swings the driven arm 27 via the connecting rod 29, and the driven arm 27 swings the swing deck 24 by swinging. The driven arm 27 is pivotally supported by a part of the frame 40 so that the intermediate point thereof can swing. An engagement roller 30 disposed at one end of the driven arm 27 is engaged with an engaged rail 31 formed on the swing deck 24, and the connecting rod 29 is connected to the other end of the driven arm 27. It is pivotally supported. On the other hand, the drive arm 28 is pivotally supported at its intermediate point in the vicinity of the inner wall of the pit P so as to be swingable. A contact roller 32 is attached to one end of the drive arm 28, and the connecting rod 29 is pivotally supported at the other end. Further, a tension coil spring 33 as an urging means for urging the driven arm 27 is attached to the other end of the driven arm 27 (the connection point of the connecting rod 29). Yes.

  Of course, on the contrary, a tension coil spring may be attached so that the swing deck 24 is biased in the upward swinging direction. In this case, the swing drive mechanism needs to swing the swing deck 24 downward by pushing the contact roller of the drive arm. This can be easily configured such that the end of the connecting rod 29 is also attached to the attachment portion of the contact roller 32 of the illustrated drive arm 28.

  The operation of the swing drive mechanism having such a configuration will be described. As shown in FIG. 8, when the contact roller 32 of the drive arm 28 is pushed leftward (arrow A) in the figure, the drive arm 28 rotates counterclockwise and pulls the connecting rod 29 in the arrow B direction. As a result, the driven arm 27 rotates counterclockwise (arrow C direction) against the urging force of the tension coil spring 33, and the engagement roller 30 rotates upward. Then, it contacts the stopper 44 beyond the dead point to the left. The stopper 44 is installed at the end of the engaged rail 31. The dead point is the point at which the deflection (spring restoring force) of the spring 33 becomes the largest, and the driven arm 27 is vertical in this embodiment. As a result, the swing deck 24 is swung upward via the engaged rail 31 and becomes a horizontal state, and forms a part of the roadway.

  As shown in FIG. 7, when the force that presses the contact roller 32 of the drive arm 28 is released, the driven arm 27 rotates clockwise (arrow D) by the urging force of the tension coil spring 33 and exceeds the dead point. Thereafter, the swing deck 24 swings downward by its own weight. In this manner, the swing deck 24 swings downward by the spring force until the dead point is exceeded, and thereafter swings downward by its own weight. At this time, since the connecting rod 29 is pulled leftward (arrow F) in the figure, the drive arm 28 is rotated clockwise (arrow G), and the contact roller 32 projects into the pit P. The attachment target of the tension coil spring 33 is not particularly limited to the driven arm 27, and may be attached to any of the swing deck 24 itself, the drive arm 28, and the connecting rod 29, for example. In short, as shown in FIG. 7, it is only necessary for the driven arm 27 to apply an elastic urging force in a direction in which the driven arm 27 exceeds the dead point (vertical position of the driven arm) by clockwise rotation.

  As shown in FIG. 8, in this embodiment, it is the side surface of the lift floor 15 that pushes the contact roller 32 of the drive arm 28 in the direction of arrow A. That is, when the elevating floor 15 rises to the upper surface of the pit to form a roadway, the side surface pushes the contact roller 32 of the drive arm 28. As a result, a roadway is formed by the swing deck 24 and the lift floor 15 in a horizontal state. At this time, since the elevating floor 15 is stopped at the raised position, the state in which the pressing force is applied from the elevating floor 15 to the drive arm 28 is maintained. Further, since the engagement roller 30 of the driven arm 27 slightly exceeds the dead point and is in contact with the stopper 44 installed at the end of the engaged rail 31, the weight of the vehicle is added to the upper surface of the swing deck 24. However, the swing deck does not swing downward.

  Further, as shown in FIGS. 5 and 7, when the elevating floor 15 is lowered toward the first lowered position or the second lowered position in order to place the elevator 4 thereon, the contact roller 32 by the elevator 4 is used. The above pressing force is released. Then, the counterclockwise moment of the driven arm 27 caused by the action of the weight of the swing deck 24 overcomes the moment that rotates the driven arm 27 in the clockwise direction by the spring force of the spring 33, and the driven arm 27 rotates in the clockwise direction. Since it is rotated, the swing deck 24 swings downward. At this time, the vicinity of the rocking end of the rocking deck 24 is lowered by the height of the traversing wheel 25 of the pallet 12. As a result, the pallet 12 turned 90 ° and lowered again to the floor surface of the loading / unloading floor falls into the part of the swing deck 24 (the recess 26) where the traversing wheel 25 on the lower surface descends, and the pallet 12 vehicle The placement surface is exactly the same as the vehicle travel floor on the entry / exit floor.

  As shown in FIG. 7, the traverse wheel support member is positioned at a position facing the traverse wheel 25 of the pallet 12 just placed on the frame 40 corresponding to the vicinity of the swing end of the swing deck 24. 34 (hereinafter also simply referred to as a support member) is provided. The support member 34 is a combination of a plurality of cylindrical members nested. The support member 34 passes through a rectangular through hole (not shown) formed in the vicinity of the rocking end of the rocking deck 24 so that the face is seen above the rocking deck 24. A flat mounting plate 36 having a side larger than the short side of the through hole is fixed to the upper end of the support member 34, and the traversing wheel 25 of the lowered pallet rides on the mounting plate 36 (FIG. 7). reference). At this time, the weight of the pallet 12 is supported by inserting the inner cylinder 34a of the support member into the outer cylinder 34b and reaching the bottom, or the outer cylinder 34b supports this weight. In order for this support member 34 to function effectively, the descending dimension of the rocking end due to the rocking of the rocking deck 24 is made larger than the vertical dimension of the traversing wheel of the pallet.

  On the other hand, when the swing deck 24 swings upward so as to be in a horizontal state, the support plate 34 is lifted by the swing deck so that the inner cylinder 34a extends upward. The mounting plate 36 closes the through hole. By providing this support member 34, the descending dimension of the pallet 12, that is, the amount of falling of the traverse wheel or traverse rail can be easily determined (up and down positioning of the pallet). As a result, the troublesome work of accurately defining the swing angle of the swing deck 24, that is, the descending amount of the swing end, can be omitted.

  With reference to FIG. 9, the operation of the parking apparatus 1 having the above-described configuration, that is, the operation control by the control apparatus 39 will be described by taking the warehousing operation as an example. First, the warehousing operation to the entrance side parking tower 2 will be described. In this case, there is no movement related to entering the entrance side parking tower 2 in the back side parking tower 3. When an entry request is made by the operation control panel 38 (FIG. 2) outside the entrance / exit 20, the elevator floor 15 descends to the pallet turning position. Accordingly, the swing deck 24 swings downward. Then, as shown in FIG. 9A, when the first elevator 4 places the empty pallet 12 and lands on the elevating floor 15 in the pit, as shown in FIG. Operates and turns the pallet 90 °. Then, the longitudinal direction of the pallet 12 is directed in a direction (incoming / outgoing direction) where the longitudinal direction intersects with the longitudinal direction of the lifting floor 15 at a right angle.

  Next, as shown in FIG. 9C, when the elevating floor 15 is lowered to the lowest position, the front and rear traversing wheels 25 of the pallet 12 are placed on the swing deck portion (recess 26) that is lowered by the swing. Depressed. The traverse wheel 25 rides on the upper end of the support member 34 (FIG. 7). At this time, the vehicle placement surface of the pallet 12 substantially coincides with the vehicle traveling floor surface of the entry / exit floor E. The entering vehicle M enters from the entrance / exit and gets on the pallet 12. When it is confirmed that the vehicle M has stopped at an appropriate position on the pallet 12, the driver gets off and leaves. Next, as shown in FIG. 9D, the elevating floor 15 is raised to the pallet turning position, and the pallet 12 is turned 90 °. If it does so, the pallet 12 will be in the state in which the longitudinal direction corresponded to the longitudinal direction of the raising / lowering floor 15 and the longitudinal direction of a parking shelf. The elevator then moves up to the designated parking shelf floor, and the lateral feed device 14 (FIG. 3) transfers the vehicle to the parking shelf. The exit operation from the entrance side parking tower 2 operates in the reverse order of the exit operation described above.

  Next, the warehousing operation to the berth parking tower 3 will be described with reference to FIG. In this case, together with the warehousing preparation operation (FIGS. 10 (c) and 10 (d)) in the back side parking tower 3, an operation for forming a roadway on the entry / exit floor E of the entrance side parking tower 2 (FIG. a) and FIG. 10 (b)) proceed. First, in the back side parking tower 3, the second elevator 5 equipped with the turning device 13 and the lateral feed device 14 descends to the loading / unloading floor and is landed on the concrete platform T in the pit P. At this time, the vehicle placement surface of the pallet 12 substantially coincides with the vehicle traveling floor surface of the entry / exit floor E. Next, the swing deck 45 swings downward, and the pallet 12 is swung by the swiveling device 13, and the longitudinal direction thereof faces the loading / unloading direction. Next, the swing deck 45 returns to the horizontal state to form a part of the roadway and prepares for warehousing.

  On the other hand, in the entrance-side parking tower 2, the first elevator 4 is retreated above the entry / exit floor E, and as shown in FIG. Form. As the elevator floor 15 is raised, the swing deck 24 swings upward as described above to form a roadway in a horizontal state. As shown in FIG. 10B, the warehousing vehicle M moves to the far side parking tower 3 through this roadway. As shown in FIG. 10 (c), the warehousing vehicle M passes over the swing deck 45 and gets on the pallet 12 on the entry / exit floor of the back parking tower 3. Next, as shown in FIG. 10D, the pallet 12 is turned 90 °. At this time, the swing deck 45 swings downward. If it does so, the pallet 12 will be in the state in which the longitudinal direction corresponded to the pit P and the longitudinal direction of the parking shelf. The elevator then moves up to the designated floor of the parking shelf, and the lateral feed device 14 transfers the vehicle to the parking shelf. The delivery work from the back side parking tower 3 operates in the reverse order of the delivery operation described above.

  The swing deck 24 described above is configured to swing in conjunction with the lifting and lowering of the lifting floor 15. Specifically, the raising / lowering operation of the raising / lowering floor 15 serves as a driving force source for swinging the swing deck. Therefore, energy can be saved, and the equipment cost and operation cost can be reduced.

  However, it is not limited to such a configuration. For example, you may comprise as follows. In other words, the swing drive mechanism of the swing deck 24 includes a feed screw mechanism or chain mechanism driven by an electric motor independent of the lift floor 15 or a hydraulic cylinder. Then, when an entry / exit request for the rear parking tower 3 is made through the driving operation panel 38, the control device 39 moves the swing deck 24 upward with respect to the swing drive mechanism based on a command from the driving operation panel 38. A command is made to swing, and the road is formed. Further, when an entry / exit request for the entrance-side parking tower 2 is made, the control device 39 instructs the swing drive mechanism to swing the swing deck 24 downward based on a command from the operation control panel 38. Thus, a storage space for the traverse wheel of the pallet is formed.

  FIGS. 11 and 12 show an elevator parking apparatus 41 of a 180 ° riding type. This parking device 41 is such that the longitudinal direction of the elevators 4 and 5 faces the same direction as the loading / unloading direction. And all the parking shelves 11 are also installed such that the longitudinal direction thereof is parallel to the longitudinal direction of the elevators 4 and 5. The elevators 4 and 5 here are the same in configuration as the elevators (FIGS. 1 to 7) in the above embodiment except for the direction of the longitudinal direction. Therefore, the same code | symbol is attached | subjected. When the vehicle enters and leaves the parking device 41, the pallet is turned 180 ° on the elevator landing in the pit so that the vehicle is turned in the opposite direction. This is because both the entering and leaving of the vehicle are performed by the forward movement.

  In the pit P of the entrance side parking tower 42, the same lift floor 15 as that in the parking tower 2 (FIGS. 1 to 7) is disposed. The elevator floor 15 has the same configuration as the elevator floor of the parking tower 2 except that the longitudinal direction of the elevator floor 15 is different from that of the parking tower 2 in the longitudinal direction. In addition, the same code | symbol is attached | subjected to the element of the same structure as the above-mentioned parking apparatus 1, and the description is abbreviate | omitted. The elevating floor 15 is also composed of the first lowered position for the elevators 4 and 5 to ride, the second lowered position for turning the pallet, and the raised position for forming a roadway. Stop at each position. Further, the parking device 41 is not provided with a swing deck or a swing drive mechanism. This is because the swinging deck is not required because the pallet is turned 180 ° instead of 90 °.

  According to the parking device 41, the elevating deck 15 stops at the second lowered position in order to turn the pallet in the entrance side parking tower 42. There is no need to install a lifting device in the elevator or to lift the elevator itself a little. In addition, since the lift floor is raised to form a vehicle road that passes through the entrance-side parking tower 42, it is not necessary to lower the elevator to the loading / unloading floor as in the prior art.

  In the rear side parking tower 43, no lift floor is installed in the pit P, and only an elevator enters. This is because the vehicle does not pass through the entrance / exit floor of the back side parking tower 43, so that it is not necessary to form a roadway. The floor surface around the pit P is slightly lower than the vehicle traveling surface, and the swing deck 45 is disposed from the vehicle passage opening 22 toward the floor surface of the rear parking tower 43. 1 (FIGS. 1 and 2). The shape of the pit P in plan view is almost the same as that of the elevator 5. At the bottom of the pit P, a concrete base T having the same height as the lift floor 15 of the entrance side parking tower 42 is formed. In the back side parking tower 43, when the elevator 5 reaches the entry / exit floor, the turning device gets on the concrete platform T. The elevator descends to a position where it does not interfere when the pallet turns, and rises to the original position after turning the pallet to support the traversing wheel of the pallet. When the pallet turns, the swing deck 45 swings downward. Therefore, it is not necessary to slightly raise the turning device and the pallet when turning the pallet as in the prior art.

  As described above, in both the 90 ° boarding type parking device 1 and the 180 ° boarding type parking device 41, a simple concrete platform is formed in the pit of the far side parking tower without providing a lift floor. . However, it is not particularly limited to this configuration, and an elevating floor may be provided in the pit as in the entrance side parking tower. In that case, it is not necessary to make the floor surface slightly lower than the vehicle traveling floor surface by configuring the lifting floor to stop at the second lowered position described above.

  The parking apparatus according to the present invention does not require an elevator to be lowered to the entry / exit floor in order to form a roadway in the pit portion of the entry / exit floor, and also employs a pallet having a traverse rail and a traverse wheel. Even so, there is no fear that the wheel of the passing vehicle falls into the accommodation space of the traverse wheel and traverse rail on the road.
