[First embodiment]
FIG. 1 is a front view of a fork-type parking apparatus according to a first embodiment of the present invention viewed from a horizontal and vertical direction. 2 is a view taken along the line II-II in FIG. 3 is a view taken along the line III-III in FIG. Each parking floor other than the parking floors shown in FIGS. 2 and 3 also has the same configuration as FIGS. 2 and 3.

  The fork type parking apparatus 10 includes a lift 1, a tray delivery space 3, and a transverse fork tray 5.

  The lift 1 can be raised and lowered between an entry / exit floor where vehicles enter and exit and a parking floor where vehicles are parked, and can be raised and lowered between a plurality of parking floors. In FIG. 1, the entry / exit floor is the lowest floor and is located on the ground, and the plurality of parking floors are located above the entry / exit floor. The lift 1 includes a lift-side fork 1b for loading a vehicle and a lift frame 1a that is lifted and lowered in the hoistway 7 to which the lift-side fork 1b is fixed. The lift frame 1a is provided with a guided portion 1a1 (for example, a guide roller). The lifting and lowering of the lift frame 1a is guided to the guide rail 23 via the guided portion 1a1. The guide rail 23 extends in the vertical direction. In FIG. 2, four guide rails 23 are respectively provided at the four corners of the hoistway 7 when viewed from the vertical direction. The lift frame 1a is suspended by four cords 25 (chains, wires, etc.). The four ropes 25 are moved up and down by, for example, a lift drive device 27 (motor in FIG. 1) shown in FIG. 1, so that the lift frame 1a is driven up and down.

  The lift 1 has a tray support mechanism 1c. The tray support mechanism 1c is between a non-elevating support state supported by the parking floor structure 12 and a lift support state supported by the lift frame 1a among the parking floor structure 12 that does not move up and down and the lift frame 1a that moves up and down. Can be switched. The parking floor structure 12 is a structure that is fixed with respect to the ground to form a parking floor, or a structure provided in the structure. In FIGS. 2 and 3, the parking floor structure 12 is a locking portion described later provided on the guide rail 23. In FIG. 3 and FIGS. 4 to 9 to be described later, the locked member 1c4 and the locking portion 12, and each portion described later used for driving the locked member 1c4 are components of the tray support mechanism 1c. Although they are shifted in the horizontal and vertical direction (the back side of the paper) from the top (see FIG. 2), all of these are shown through to facilitate understanding. In FIG. 3, the tray support mechanism 1c is in a non-elevating support state. The raising / lowering support state of the tray support mechanism 1c is, for example, a state shown in FIG.

  The tray delivery space 3 is provided on each parking floor and is adjacent to the hoistway 7 of the lift 1 in the horizontal horizontal direction. In FIG. 1, on each parking floor, the tray delivery space 3 is provided in the hoistway 7 on both sides in the horizontal and horizontal directions. Moreover, in FIG. 1, the tray delivery space 3 is a parking space of a vehicle.

  The transverse fork tray 5 is movable in the horizontal and lateral directions between the hoistway 7 of the lift 1 and the tray delivery space 3. The transverse fork tray 5 is a tray for loading a vehicle. The traverse fork tray 5 is provided in the tray delivery space 3 (in FIG. 1, each tray delivery space 3) in each parking floor.

  According to this embodiment, the tray support mechanism 1c functions as follows. The tray support mechanism 1c brought into the non-lifting support state at a height corresponding to any arbitrary parking floor transfers the traverse fork tray 5 to and from the tray transfer space 3 on the parking floor. Further, when the tray support mechanism 1c in the non-lifting support state receives the traverse fork tray 5 from the tray delivery space 3 and supports the traverse fork tray 5, the lift-side fork 1b is moved by the lift frame 1a. By passing the traverse fork tray 5 in the vertical direction, the vehicle is remounted between the lift-side fork 1 b and the traverse fork tray 5. On the other hand, the tray support mechanism 1c in the lift support state moves up and down together with the lift frame 1a.

  Hereinafter, the configuration of the fork type parking apparatus 10 according to the present embodiment will be described in more detail.

  The tray support mechanism 1c is arranged so as to be shifted in the horizontal direction from the lift-side fork 1b so as not to interfere with the lift-side fork 1b. In FIG. 2, the tray support mechanisms 1 c are provided on both sides of the lift-side fork 1 b in the horizontal and vertical direction so as to be shifted outward in the vertical direction from the lift-side fork 1 b. Each tray support mechanism 1c is provided in a roller support portion 1c1 extending in the horizontal and horizontal directions, a plurality of transverse rollers 1c2 rotatably attached to the roller support portion 1c1 at intervals in the horizontal and horizontal directions, and the roller support portion 1c1. And a roller driving device 1c3 that rotationally drives at least one of the plurality of transverse rollers 1c2. The plurality of transverse rollers 1c2 receive the transverse fork tray 5 from a tray transverse device 9 (described later) in the tray delivery space 3, whereby the transverse fork tray 5 is supported on the upper surfaces of the plurality of transverse rollers 1c2. Further, the roller driving device 1c3 rotationally drives the traverse roller 1c2 to move the traverse fork tray 5 on the traverse roller 1c2 in the horizontal lateral direction to the tray delivery space 3, thereby moving the traverse fork tray 5 to the tray traverse device. Pass to 9.

  In this example, the roller driving device 1c3 is a motor. The motor 1c3 drives the sprocket 4 to rotate. Thereby, the chain 6 hung on the sprocket 4 is driven. When the chain 6 is driven, the sprocket 8 on which the chain 6 is hung is driven to rotate. As a result, the transverse roller 1c2 with the sprocket 8 fixed coaxially is driven to rotate.

  The transverse fork tray 5 is provided in each tray delivery space 3. In each parking floor, the traverse fork tray 5 of each tray delivery space 3 is placed horizontally between the tray delivery space 3 and a tray support mechanism 1c that is in a non-lifting support state at a height corresponding to the parking floor. Passed in the direction.

  In each tray delivery space 3, a traverse fork tray 5 is placed, and a tray traverse device 9 is provided to support the tray. The tray traversing device 9 in each tray delivery space 3 moves the traverse fork tray 5 in the horizontal lateral direction onto the tray support mechanism 1c in the non-lifting support state adjacent to the tray traversing device 9 in the horizontal lateral direction. The traverse fork tray 5 is received and supported from the tray support mechanism 1c.

  2 and 3, the tray traverse device 9 includes a pair of traverse roller frames 9a and a plurality of traverse rollers 9b. The pair of transverse roller frames 9a are provided on both sides in the horizontal and vertical direction in the tray delivery space 3, respectively. Each transverse roller frame 9a rotatably supports a plurality of transverse rollers 9b arranged at intervals in the horizontal transverse direction. In each transverse roller frame 9a, at least one of the transverse rollers 9b is driven to rotate, thereby causing the transverse fork tray 5 placed on the plurality of transverse rollers 9b to move horizontally toward the hoistway 7 side.

  The traverse fork tray 5 and the lift side fork 1b on the tray support mechanism 1c are passed to the tray support mechanism 1c so that the lift side fork 1b can pass up and down through the traverse fork tray 5 positioned on the tray support mechanism 1c. In this state, each has comb-shaped portions that do not overlap each other in the vertical direction. In FIG. 2, the alternate long and short dash line indicates the traverse fork tray 5 when it is moved from the tray delivery space 3 onto the tray support mechanism 1c.

  The tray support mechanism 1c in the lift support state moves up and down together with the lift frame 1a. When the tray support mechanism 1c is in the lift support state, the tray support surface that supports the traverse fork tray 5 in the tray support mechanism 1c (that is, the upper surface of the traverse roller 1c2) is positioned below the upper surface of the lift side fork 1b. Yes. The upper surface of the lift-side fork 1b is a surface on which vehicle tires are loaded.

  The tray support mechanism 1c has a locked member 1c4. The locked member 1c4 includes a locking position locked to the parking floor structure (the locking portion 12 provided on the guide rail 23 in FIG. 3) in order to place the tray support mechanism 1c in a non-lifting support state. It is driven between a non-locking position that is not locked by the locking part 12. In FIG. 3, the locked member 1c4 is driven between the locked position and the unlocked position by being driven to rotate about the central axis C.

  The tray support mechanism 1c is provided with a driving device 16 that drives the locked member 1c4 between the locking position and the non-locking position.

In the present embodiment, the elastic force that pushes the locked member 1c4 toward the locking position acts on the locked member 1c4. Therefore, in a state where the driving device 16 is not operated, the locked member 1c4 is positioned at the non-locking position by the above-described elastic force (for example, the state shown in FIG. 4A described later).
When actuated, the driving device 16 moves the locked member 1c4 to the locking position against the elastic force described above, and maintains the locked member 1c4 in the locking position (for example, the state of FIG. 3).

  An example of the structure for applying the elastic force and the driving device 16 as described above will be described with reference to FIG. However, the drive device 16 is not limited to the configuration shown in FIG. 3 as long as the member to be locked 1c4 is operated between the locking position and the non-locking position.

  In order to apply the above-described elastic force, the tray support mechanism 1c is provided with first and second spring support members 11 and 13, a coil spring 15, a wire 17, and a bracket 19. The first spring support member 11 is fixed to the tray support mechanism 1c. One end of the coil spring 15 is fixed to the first spring support member 11, and the other end of the coil spring 15 is fixed to the second spring support member 13. The second spring support member 13 is movable with respect to the first spring support member 11 according to the compression amount of the coil spring 15. The second spring support member 13 and the bracket 19 are connected to each other by a wire 17. The bracket 19 is fixed to the locked member 1c4. One end of the wire 17 is coupled to the second spring support member 13. The wire 17 extends from one end thereof, passes through the central portion of the coil spring 15, further passes through the first spring support member 11, and the other end is coupled to the bracket 19.

  The drive device 16 is a telescopic cylinder device. The tip of the piston of the telescopic cylinder device 16 and the bracket 19 are connected to each other by a wire 21. Therefore, when the telescopic cylinder device 16 is operated from the state where the locked member 1c4 is in the non-locking position (for example, the state of FIG. 4A), the piston of the telescopic cylinder device 16 moves backward from the advanced state. As a result, when the telescopic cylinder device 16 contracts, the bracket 19 is moved away from the first spring support member 11 via the wire 21 against the elastic force of the coil spring 15 in the compressed state. As a result, the locked member 1c4 moves from the non-locking position to the locking position. In addition, Preferably, the wire 21 is arrange | positioned inside the tubular member (not shown) fixed to the tray support mechanism 1c, and can move with respect to the tubular member along the tubular member.

  In FIG. 2 and FIG. 3, the locked member 1c4 is provided at each end in the horizontal direction of each tray support mechanism 1c. In this case, as shown in FIG. 3, one set of drive device 16 and wire 21 may be provided for a plurality (two or four) of the locked members 1c4, and each locked One set of the driving device 16 and the wire 21 may be provided for the member 1c4.

  In this embodiment, the latching | locking part 12 which latches the to-be-latched member 1c4 of a latching position is being fixed to each guide rail 23 by the height corresponding to each parking floor. In this case, four locking portions 12 are provided for each parking floor. Accordingly, four locked members 1c4 are provided corresponding to the four locking portions 12, respectively. Each locking portion 12 projects in the horizontal and lateral direction from the guide rail 23 to the inside of the hoistway 7.

  The lift frame 1a has a fall prevention part 1a2. The drop prevention unit 1a2 supports the tray support mechanism 1c from below to place the tray support mechanism 1c in a lift support state, and prevents the tray support mechanism 1c from dropping from the lift frame 1a. The fall prevention part 1a2 is provided at both lateral ends of each tray support mechanism 1c. Each fall prevention part 1a2 supports the horizontal direction edge part of the corresponding tray support mechanism 1c from the downward direction. In FIG. 3, each fall prevention part 1a2 protrudes from the component part of the lift flame | frame 1a to the inner side of the hoistway 7 in the horizontal horizontal direction. On the other hand, the supported portion 1c5 of the tray support mechanism 1c supported by the fall prevention portion 1a2 protrudes in the horizontal lateral direction facing the outside of the hoistway 7 from the component part of the tray support mechanism 1c.

  The lift frame 1a and the tray support mechanism 1c are provided with a guide mechanism 18 for guiding the relative vertical movement between the tray support mechanism 1c and the lift frame 1a in the non-lifting support state. In the present embodiment, the guide mechanism 18 includes a guide portion 1d provided on the lift frame 1a and a guided portion 1c6 provided on the tray support mechanism 1c. The guide 1d guides the vertical movement of the tray support mechanism 1c relative to the lift frame 1a. The guide portions 1d are provided at both lateral ends of each tray support mechanism 1c. Each guide portion 1d guides the relative vertical movement of a guided portion 1c6 (the roller 1c6 in FIGS. 2 and 3) provided at the lateral end of the tray support mechanism 1c. In FIG. 3, the guide portion 1d is sandwiched between a pair of rollers 1c6 extending in the vertical direction and rotatable about the horizontal axis. In FIG. 3, each guide part 1d is located above the fall prevention part 1a2.

  As described above, the tray support mechanism 1c that can be raised and lowered with respect to the lift frame 1a is prevented from dropping from the lift frame 1a by the above-described drop prevention portion 1a2. Therefore, the tray support mechanism 1c can be moved up and down with respect to the lift frame 1a within a set range above the position supported from below by the fall prevention portion 1a2. The guide portion 1d extends in the vertical direction over this set range.

  According to this embodiment, each fall prevention part 1a2 and each guide part 1d are located in the vicinity of the guide rail 23 which guides the raising / lowering of the lift frame 1a.

  Note that the roller driving device 1c3, the driving device 16, and the driving device 29c described later provided in the tray support mechanism 1c may be operated by electric power. In this case, the power supply to the tray support mechanism 1c may be performed as follows, for example. The front end portion of the power supply line is attached to the tray support mechanism 1c, and the power supply line is lowered in the hoistway 7 downward from the top floor of the fork type parking apparatus 10 in accordance with the raising / lowering of the tray support mechanism 1c in the lift support state.

For example, in the target parking floor specified by the command signal, the locked position The to-be-latched member 1c4 is latched by the latching | locking part 12, and the tray support mechanism 1c is changed from a raising / lowering support state to a non-elevating / lowering support state. This state is shown in FIG.

  In this operation (5), when another parking floor exists between the target parking floor and the entry / exit floor, the tray support mechanism 1c is in the lift support state supported by the fall prevention unit 1a2, and With the locked member 1c4 in the unlocked position, the lift frame 1a is raised or lowered until the locked member 1c4 is positioned slightly above the locking portion 12 of the target parking floor. Next, the locked member 1c4 is positioned at the locking position, and the lift frame 1a is lowered, whereby the locked member 1c4 is locked to the locking portion 12 of the target parking floor. Thus, the tray support mechanism 1c is changed from the lift support state to the non-lift support state.

  In order to execute the operation (5), the control device 30 controls the position of the locked member 1c4 as described above through controlling the drive device 16 and controls the lift drive device 27. As a result, the lift frame 1a is operated as described above.

(6) By lowering the lift frame 1a while maintaining the tray support mechanism 1c in the non-lifting support state, the upper surface of the lift-side fork 1b is moved from the tray support surface of the tray support mechanism 1c (the upper surface of the transverse roller 1c2). Is also lowered. This state is shown in FIG.

  In such an operation (6), the control device 30 operates the lift frame 1a as described above through controlling the elevating drive device 27.

(7) On the target parking floor, the transverse fork tray 5 loaded with vehicles is moved from the tray delivery space 3 to the tray support mechanism 1c in the horizontal and horizontal direction. This state is shown in FIG.

  In order to execute such an operation (7), the control device 30 controls the driving device (not shown) of the tray traversing device 9 or both the driving device of the tray traversing device 9 and the roller driving device 1c3. The traverse fork tray 5 is operated as described above.

(8) The lift fork 1b is lifted together with the lift frame 1a from below the traverse fork tray 5 on the tray support mechanism 1c in the non-lifting support state, thereby moving the vehicle on the traverse fork tray 5 to the lift fork 1b. Put it on top. This state is shown in FIG.

  In order to execute such an operation (8), the control device 30 operates the lift frame 1a as described above through controlling the elevating drive device 27.

(9) The traverse fork tray 5 is traversed back from the tray support mechanism 1c to the tray delivery space 3, and then the lift-side fork 1b is moved vertically to the loading / unloading floor together with the lift frame 1a.

  In this operation (9), when the traverse fork tray 5 is returned to the tray delivery space 3 and then the lift frame 1a is raised to bring the tray support mechanism 1c into the lift support state, the locked member 1c4 is moved to the unlocked position. The lift frame 1a is raised or lowered to the loading / unloading floor.

  In order to execute such an operation (9), the control device 30 controls the roller driving device 1c3 or the traverse fork tray 5 through controlling both the driving device of the tray traversing device 9 and the roller driving device 1c3. Is operated as described above, and the lift frame 1a is operated as described above by controlling the elevating drive device 27.

  Note that after the operation (9), the vehicle on the lift-side fork 1b is discharged from the fork-type parking device 10 (for example, by getting on the lift-side fork 1b).

[Second Embodiment]
Next, a fork type parking apparatus 10 according to a second embodiment of the present invention will be described. In the second embodiment, points not described below are the same as those in the first embodiment described above.

  FIG. 9 is a view corresponding to FIGS. 3 and 6 and shows the configuration of the fork type parking apparatus 10 according to the second embodiment of the present invention. 10A is a partially enlarged view of FIG. 9, FIG. 10B is a cross-sectional view taken along line BB of FIG. 10A, and FIG. 10C is FIG. 10A. It is a CC line arrow directional view.

  According to the second embodiment, the lift 1 includes the holding device 29 that holds the tray support mechanism 1c on the lift frame 1a. The tray support surface (the upper surface of the transverse roller 1c2) of the tray support mechanism 1c brought into the non-lifting support state is positioned above the upper surface (the surface on which the vehicle tire is loaded) of the lift side fork 1b. With the positional relationship between the support mechanism 1c and the lift frame 1a (for example, the positional relationship in FIG. 9 corresponding to FIGS. 3 and 6), the holding device 29 causes the lift frame 1a to hold the tray support mechanism 1c. This positional relationship is maintained.

  In the second embodiment, the warehousing method is the same as that of the first embodiment, but the warehousing method is different from the first embodiment in that it will be described later.

  The operation of the holding device 29 to hold the tray support mechanism 1c on the lift frame 1a is performed when the tray support mechanism 1c is brought into the non-lifting support state by the locking portion 12. For example, this operation may be performed when the state shown in FIG. 9 corresponding to FIG. 6 (or the state corresponding to FIG. 5B) is reached in the operation procedure of the warehousing method described above. In addition, you may provide the latching | locking part 12 for making the tray support mechanism 1c into a non-elevating support state when hold | maintaining the tray support mechanism 1c to the lift frame 1a in a storage floor.

  The holding device 29 holds a holding portion 29a that is provided on the lift frame 1a and holds the tray support mechanism 1c, a held member 29b that is provided on the tray supporting mechanism 1c and is held by the holding portion 29a, and a held member 29b. A driving device 29c that is driven between a holding position held by the portion 29a (state shown in FIG. 10) and a non-holding position not held by the holding portion 29a (state shown in FIG. 11).

  FIGS. 11A, 11B, and 11C correspond to FIGS. 10A, 10B, and 10C, respectively, but show a state in which the holding device 29 does not hold the tray support mechanism 1c.

  The holding portion 29a has, for example, a horizontally elongated hole 29a1 extending in a first horizontal direction (horizontal vertical direction in FIG. 9) penetrating in the vertical direction. In this case, the held member 29b is provided at a position that is aligned with the laterally long hole 29a1 in the vertical direction, and is rotated by the drive device 29c around the rotation axis C1 that faces in the vertical direction, so that the holding position and the non-holding position are set. Driven between. The held member 29b cannot pass through the horizontally long hole 29a1 in the vertical direction in the state where it is held, but is held by the holding portion 29a. In the state where it is in the non-holding position, it can pass through the horizontally long hole 29a1 in the vertical direction. Not retained.

In this example, an elastic force that pushes the held member 29b toward the holding position side acts on the held member 29b. Therefore, in a state where the driving device 29c is not operating, the held member 29b is positioned at the non-holding position by the above-described elastic force (the state shown in FIG. 11).
The tray support mechanism 1c is provided with a drive device 29c. When actuated, the driving device 29c moves the held member 29b to the holding position against the elastic force described above, and maintains the tray support mechanism 1c at the holding position (state shown in FIG. 10).

  An example of the structure for applying the elastic force and the driving device 29c as described above will be described with reference to FIGS. However, the drive device 29c is not limited to the configurations of FIGS. 9 to 11 as long as the held member 29b is operated between the holding position and the non-holding position.

  In order to apply the above-described elastic force, the tray support mechanism 1c is provided with first and second spring support members 31, 33, a coil spring 35, a wire 37, and a bracket 39. The first spring support member 31 is fixed to the tray support mechanism 1c. One end of the coil spring 35 is fixed to the first spring support member 31, and the other end of the coil spring 35 is fixed to the second spring support member 33. The second spring support member 33 is movable with respect to the first spring support member 31 according to the compression amount of the coil spring 35. The second spring support member 33 and the bracket 39 are connected to each other by a wire 37. The bracket 39 is fixed to the held member 29b. One end of the wire 37 is coupled to the second spring support member 33. The wire 37 extends from one end thereof, passes through the central portion of the coil spring 35, further passes through the first spring support member 31, and the other end is coupled to the bracket 39.

  The drive device 29c is a telescopic cylinder device. The tip of the piston of the telescopic cylinder device 29 c and the bracket 39 are connected to each other by a wire 41. Accordingly, when the telescopic cylinder device 29c is operated from the state where the held member 29b is in the non-holding position (the state shown in FIG. 11), the piston of the telescopic cylinder device 29c moves backward from the advanced state. As a result, when the telescopic cylinder device 29 c contracts, the bracket 39 is moved away from the first spring support member 31 via the wire 41 against the elastic force of the coil spring 35 in the compressed state. As a result, the held member 29b moves from the non-holding position to the holding position. Preferably, the wire 41 is disposed inside a tubular member (not shown) fixed to the tray support mechanism 1c, and is movable along the tubular member with respect to the tubular member.

  In addition, the to-be-held member 29b is provided in each edge part of the horizontal direction of each tray support mechanism 1c in FIG. In this case, as shown in FIG. 10 and FIG. 11, a set of driving devices 29c and wires 41 may be provided for the plurality of held members 29b, or for each held member 29b, One set of drive device 29c and wire 41 may be provided.

  Next, the delivery method of the fork type parking apparatus 10 according to the second embodiment will be described.

  In the case where the lift 1 includes the above-described holding device 29, the control device 30 controls the holding device 29 (drive device 29c) before starting the operation (5), so that the lift-side fork 1b. The tray supporting mechanism 1c positioned below the lift frame 1a is held by the holding device 29. In this state, the control device 30 causes each part of the fork type parking device 10 to execute the operation (5).

The control device 30 performs the operations (7) to (9) without performing the operation (6) after performing the operation (5).
However, after the operation (5) and before the start of the operation (8), the control device 30 controls the holding device 29 (drive device 29c) to move the held member 29b from the holding position. Move to the non-holding position.

  According to the second embodiment, since the operation (6) can be omitted, the time required for leaving can be shortened.
