Description

  The present invention relates to a fork type parking apparatus and a control apparatus therefor.

  The fork-type parking apparatus includes a comb-like lift that moves up and down the hoistway and a comb-like tray provided in a parking space on each parking floor. The comb-like tray of each parking space traverses horizontally between the parking space and the hoistway. The comb lift and the comb tray have a comb shape that does not overlap in the vertical direction so that the comb lift can pass up and down the comb tray with the comb tray positioned in the hoistway.

  The fork type parking apparatus includes a turning table for turning the automobile. The turning table is provided in the hoistway on the lowest floor, for example. The swivel table also has a comb shape that does not interfere with the comb lift in the vertical direction so that the comb lift can pass up and down the swivel table.

In a fork type parking device, as an example, the warehousing operation is performed in the following order.
Prior to warehousing, the comb lift is waiting at a position below the turning table. The car gets on the turntable with the car facing forward on the lowest floor. Next, the turning table turns 180 degrees to change the direction of the automobile 180 degrees. Thereafter, the comb-shaped lift passes from the lower side to the upper side of the turning table, whereby the automobile is transferred from the turning table to the comb-like lift.
The comb-like lift rises from the loading / unloading floor to a position above the target parking floor among the plurality of parking floors. Next, the comb-shaped tray on the target parking floor traverses from the parking space to the hoistway. Thereafter, the comb lift descends and passes through the comb tray. As a result, the automobile is transferred from the comb lift to the comb tray. After that, the comb-shaped tray on which the car is placed crosses into the parking space. Thereby, a motor vehicle moves to a parking space and this motor vehicle is stored in a parking space until it leaves.
Car exit operation is performed in the reverse procedure of the entry operation. However, in this example, the turntable does not have to be turned at the time of delivery. As a result, when entering the car, the car can get on the turntable forward, and when leaving the car, the car can go forward from the turntable.

  The fork type parking apparatus as described above is described in, for example, Patent Document 1 below.

  Further, Patent Document 2 describes a fork type parking device in which an entry / exit floor is an intermediate floor. In this fork type parking device, the swivel table is provided such that the upper surface thereof is the same height as the floor surface of the entry / exit floor, and from the hoistway to the storage space adjacent to the hoistway in the horizontal direction, and Conversely, it reciprocates in the horizontal direction. Thereby, when the turning table is used, the turning table is positioned in the hoistway, and when the lift passes the entry / exit floor, the turning table can be retracted to the storage space. In this way, when the intermediate floor is an entry / exit floor, the car can be turned on the intermediate floor without providing a turntable on the lowest floor.

In FIG. 3A, the turning comb-like portion 13 is in the first turning position.

  As shown in FIG. 4B, the turning comb-like portion 13 in the first turning position has a comb shape that does not overlap with the comb-like stacking portion 7 in the vertical direction. In the present embodiment, the turning comb-like portion 13 has a comb shape that does not overlap the comb-like stacking portion 7 in the vertical direction at the first turning position or the second turning position. In the present application, the first turning position is a position where the turning comb-like portion 13 does not overlap the comb-like stacking portion 7 in the vertical direction. In the present application, the second turning position may be a position where the turning comb-like portion 13 does not overlap with the comb-like stacking portion 7 in the vertical direction, or the turning comb-like portion 13 is perpendicular to the comb-like loading portion 7. It may be a position overlapping.

  The elevating drive device 15 is configured so that the turning comb-like portion 13 at the first turning position (in this embodiment, either the first turning position or the second turning position) is positioned above the comb-shaped stacking portion 7.

  As shown in FIG. 3A, the elevating drive device 15 includes, for example, a motor 15a, a drive sprocket 15b, an endless chain 15c, a plurality of nuts 15d, and a plurality of screw rod members 15e. The motor 15a is attached to the second structure 21 and rotationally drives the drive sprocket 15b. The chain 15c is hung on a drive sprocket 15b and a plurality of driven sprockets provided on the outer peripheral surfaces of the plurality of nuts 15d. Accordingly, the rotation of the drive sprocket 15b rotates the plurality of nuts 15d via the chain 15c. A female screw is formed on the inner peripheral surface of the plurality of nuts 15d, and a male screw is formed on the outer peripheral surface of the screw rod member 15e. A plurality of threaded rod members 15e are threaded through the respective nuts 15d. Each screw rod member 15e penetrates the second structure 21 with a gap, but the second structure 21 is supported from below on the upper end surface of a nut 15d screwed to each screw rod member 15e. Yes. The lower end portion of each screw rod member 15 e is fixed to the first structure 19. With this configuration, when the plurality of nuts 15d are rotationally driven by the motor 15a, each nut 15d moves up and down with respect to the screw rod member 15e. Thereby, the 2nd structure 21 currently supported by a plurality of nuts 15d from the lower part also goes up and down.

  The turning drive unit 17 drives the turning comb-shaped portion 13 located at the upper position to turn from the first turning position to the second turning position around the vertical axis C, and to turn from the second turning position to the first turning position. To do. As shown in FIG. 3A, the turning drive device 17 includes, for example, a motor 17a, a first gear 17b, a second gear 17c, and a third gear 17d. The motor 17a is attached to the second structure 21 and rotationally drives the first gear 17b. The second gear 17c is rotatably attached to the second structure 21 and meshes with the first gear 17b. The third gear 17d is formed on the outer peripheral surface of the turning member 16 and meshes with the second gear 17c. The turning member 16 is attached to the second structure 21 so as to be rotatable about the vertical axis C. The turning member 16 is integrally coupled to the turning comb-like portion 13. With this configuration, the motor 17a rotates the turning member 16 via the first gear 17b, the second gear 17c, and the third gear 17d, so that the turning comb-like portion 13 turns around the vertical axis C.

  As shown in FIG. 3A, in the lift 3, the tray gap S (between the swiveling comb-shaped portion 13 at the lower position and the comb-shaped stacking portion 7 above the swiveling comb-shaped portion 13 ( A vertical gap) is provided. The comb-shaped tray 5 can move in the horizontal direction from the tray gap S to the parking space 2 and vice versa.

  The lift 3 has a lifting platform 23. The height of the above-described tray gap S is increased from the rising height at which the upper surface of the lift 23 becomes the same height as the upper surface of the comb-shaped stacking unit 7 (that is, the upper surface of each comb tooth of the comb-shaped stacking unit 7). It is driven up and down to a lowering height lower than this, and vice versa (ie, from a lowering height to an ascending height). As shown in FIG. 4 (A), in the state where the road surface 14 of the loading / unloading floor and the upper surface of the comb-shaped stacking portion 7 are at the same height, the lifting platform 23 at the rising height is connected to the road surface 14 and the comb shape. It functions as a passage surface of the automobile 1 with the loading unit 7. That is, when the lifting platform 23 is at the raised height, as will be described later, the automobile 1 can be carried on the comb-like stacking portion 7 from the road surface 14 through the upper surface of the lifting platform 23 by self-propelling, The comb-shaped stacking unit 7 can pass through the upper surface of the lifting platform 23 to the road surface 14. The elevator 23 is positioned below the comb-like tray 5 that traverses from the parking space 2 to the tray gap S described above when the elevator 23 is at the lowered height. That is, at this time, the lifting platform 23 does not interfere with the comb-like tray 5. For example, in the state where the lifting platform 23 is at the lowered height, the upper surface of the lifting platform 23 is the same height as the upper surface of the turning comb-like portion 13 at the lower position, or the turning comb-like portion at the lower position. 13 is lower than the top surface.

  As shown in FIG. 4A, the lift 3 includes a table driving device 25 that drives the lifting table 23 up and down. For example, as shown in FIG. 4A, the table driving device 25 includes a motor 25a, a gear 25b, a nut 25c, and a screw rod member 25d. The motor 25a is attached to the first structure 19, and rotationally drives the gear 25b. The gear 25b meshes with a gear formed on the outer peripheral surface of the nut 25c. Therefore, the nut 25c is rotationally driven by the rotation of the gear 25b. The nut 25c is locked in the vertical direction by a locking member 26 fixed to the first structure 19 so that the nut 25c cannot move in the vertical direction with respect to the first structure 19, but can rotate. A screw rod member 25d passing through the nut 25c is screwed. With this configuration, the motor 25a rotates the nut 25c via the gear 25b, so that the screw rod member 25d moves up and down with respect to the first structure 19. As a result, the lifting platform 23 fixed to the upper end of the screw rod member 25d also moves up and down.

  Note that power supply to the lift drive device 15 and the turning drive device 17 on the lift 3 may be performed by a cable type or a trolley type. In the cable type, a power supply cable for supplying power to the lift 3 is unwound from the drum or wound around the drum so as to follow up and down of the lift 3. In addition, like a human elevator, one end of the power supply cable may be fixed at the center of the height of the hoistway 9, and the other end of the power supply cable may be fixed to the lift 3 to supply power to the lift 3. . In the trolley type, the lift 3 ascends and descends in a state where the electrode portion of the lift 3 is in electrical contact with a power supply line provided along the hoistway 9.

  5-7 is a figure for demonstrating operation | movement of the fork type parking apparatus 10 which has the structure mentioned above.

These support members are provided in the stationary structure of the fork type parking apparatus 10, are in a position retracted from the hoistway 9 when the lift 3 is raised and lowered, and are driven so as to protrude into the hoistway 9 when used.

  Next, as shown in FIG. 5B, the lift 3 moves up and down to the target parking floor. At this time, the lifting and lowering of the lift 3 is stopped so that the height of the above-mentioned tray gap S is the same as the height of the comb-like tray 5 on the target parking floor. In order to enable this positional relationship even if the target parking floor is the lowermost floor, the hoistway 9 is somewhat lower than the lowermost comb tray 5 as shown in FIG. It extends to.

  Next, as shown in FIG. 5C, the comb-like tray 5 is traversed from the parking space 2 to the hoistway 9 by the traversing drive device 11 in the target parking floor. That is, the comb-like tray 5 moves from the parking space 2 to the tray gap S.

  After that, as shown in FIG. 5D, the automobile 1 is transferred from the comb stacking portion 7 to the comb tray 5 when the lift 3 is lowered.

  Next, the comb-like tray 5 on which the automobile 1 is loaded is traversed from the hoistway 9 to the parking space 2 by the traversing drive device 11. Thereby, the automobile 1 on the comb-shaped tray 5 moves to the parking space 2 together with the comb-shaped tray 5 and is stored in the parking space 2 until the time of delivery.

  When there is an automobile 1 to be delivered when the lift 3 finishes the entry operation as described above, the lift 3 may perform the operation for delivery as it is. When the lift 3 finishes the above-described warehousing operation, if there is no automobile 1 to be delivered, or if there is another automobile 1 to be entered, the lift 3 moves to the entry / exit floor and the lift described above 3 is brought into the warehousing state, and the above-described operation is performed again.
