Description

  The present invention relates to a mechanical parking lot, and more particularly to a pallet-type mechanical parking lot.

  Generally, a mechanical parking lot is known as a parking lot that can efficiently park a large number of vehicles in a small space. In addition, various structures are also provided for mechanical parking lots, and as one of them, an automobile is placed on a pallet, and this pallet is moved back and forth or left and right using rails and grooves, There is a pallet-type mechanical parking lot that can be transported to an empty pallet space. In addition, a mechanical parking lot (mechanical multilevel parking lot) with higher parking efficiency is provided by combining a lift (elevating mechanism) and a three-dimensional parking layer with this pallet type mechanical parking lot.

On the other hand, various lift structures have been proposed. For example, the lift of a multilevel parking garage disclosed in Patent Document 1 is configured such that the pallet moves up and down along two columns (masts). Moreover, the lift of the multilevel parking garage disclosed by patent document 2 was set as the structure which a pallet raises / lowers along four or six support | pillars (mast).
Japanese Patent Application Laid-Open No. 08-312183 JP 2001-065186 A

  However, in the configuration in which the pallet moves up and down along the two masts disclosed in Patent Document 1, the mast is located on one side of the lift, and therefore the mast is positioned in the parking layer so that the pallet can be transferred from the lift. There are three directions excluding the arranged side portions. Moreover, in the structure which a pallet raises / lowers along the 4 or 6 mast disclosed by patent document 2, since the mast was arrange | positioned so as to oppose the long side of a pallet, a pallet is transferred from a lift in a parking layer. There are only two possible directions except for the direction in which the mast is arranged.

  Thus, in the mechanical parking lot in which the pallet is lifted and lowered by the lift, the pallet can be transferred in only three directions at the maximum, and there is no one that can transfer the pallet in four directions. For this reason, when installing a mechanical parking lot in a conventional mechanical parking lot, there is a problem that the layout is limited by the transfer direction of the pallet.

  This invention is made | formed in view of said point, and it aims at providing the mechanical parking lot which enabled the transfer of a pallet with respect to four different directions from a lift.

From the first aspect of the present invention, the above problem is
A pallet on which the vehicle is loaded,
A parking layer in which the vehicle is parked with the pallet;
A lift having a lift frame on which the pallet is mounted; and a lifting device that drives the lift frame to move up and down;
A pallet transfer device for transferring the pallet to the parking layer;
The pallet transfer device is provided in the lift, and the pallet can be transferred in four directions orthogonal to each other between the lift and the parking layer.

In addition, the above-mentioned problem is from the second viewpoint of the present invention.
A first counterweight connected to one side of the lift frame;
A second counterweight connected to the other side of the lift frame opposite to the one side and configured to be independent of the first counterweight;
Arranging the first and second counterweights together on one side of the lift;
In addition, this is solved by a mechanical parking lot in which a clearance is provided between the first counterweight and the second counterweight.

In the above invention,
Furthermore, it is good also as a structure which provided the turning apparatus which turns the said pallet in the said lift frame.

  According to the present invention, since it is possible to transfer the pallet in four directions orthogonal to each other between the lift and the parking layer, when installing a mechanical parking lot, the degree of freedom of the layout of the lift and the parking layer is increased. Can be increased.

  In addition, according to the present invention, since a plurality of counterweights are centrally arranged on one side, it is possible to prevent the counterweight from interfering with the entry / exit of the vehicle, and the degree of freedom in the entry / exit direction of the vehicle. Can be increased. In addition, since the first and second counterweights are independent from each other, the extension of the connecting member (annular chain, etc.) connected to each counterweight can be absorbed by the relative movement of each counterweight. Thus, the lift frame can be kept horizontal.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  As shown in FIG. 13, the mechanical parking lot 10 according to the present embodiment is provided with an entrance / exit 29 on the first floor, so that the vehicle 70 enters and leaves the mechanical parking lot 10 on the first floor. It is configured. However, the layer in which the passenger compartment 29 is provided is not limited to 1F, and can be provided in any layer. Therefore, the layout of the mechanical parking lot 10 should be set with a high degree of freedom. Can do.

  The mechanical parking lot 10 according to the present embodiment is a pallet type parking lot using a pallet 19. The pallet-type mechanical parking lot 10 has a vehicle 70 loaded on the pallet 19 and is moved up and down by using a lift 11 or moved in a plane direction, thereby moving the vehicle 70 on the parking shelf 12. It is set as the structure which carries out goods receipt or delivery.

  As shown in FIGS. 1 to 4, the mechanical parking lot 10 is roughly a pallet 19 on which a vehicle 70 is loaded, a lift 11 for raising and lowering the pallet 19 (vehicle 70), and the vehicle 70 together with the pallet 19. It is comprised by the parking layer 12 grade | etc., Which accommodates (parks). The lift 11 includes a lift frame 20, a pallet transfer device 21 that transfers (moves) the pallet 19 between the lift 11 and the parking layer 12, and a lift device 22 that drives the lift frame 20 up and down. Has been. Hereinafter, each component of the mechanical parking lot 10 is demonstrated.

  First, the lift 11 will be described.

  The lift 11 is installed on the installation surface 13. In short, the masts 15 to 18, the pallet 19, the lift frame 20, the pallet transfer device 21, the lifting device 22, the turning device 23, the first and second counterweights 30. , 31 and the like. The masts 15 to 18 are support columns erected on the installation surface 13, and four masts are provided in this embodiment. However, the number of masts is not limited to this. The upper ends of the masts 15 to 18 are connected by a ceiling beam 25.

  Further, intermediate positions from the installation surfaces 13 of the masts 15 to 18 to the ceiling beam 25 are connected by an intermediate beam 24. Accordingly, the masts 15 to 18 and the beams 24 and 25 constitute a lift housing 36 having a rectangular frame shape, and the intermediate beam 24 is provided to improve the strength and rigidity.

  The pallet 19 is for loading the vehicle 70 as described above, and has a rectangular shape in a plan view. The pallet 19 is arranged on the upper part of the lift frame 20. Specifically, a turning device 23 is mounted on the upper portion of the lift frame 20, and a pallet transfer device 21 is mounted on the upper portion of the turning device 23. The pallet 19 is configured to be mounted on the top of the pallet transfer device 21.

  The lift frame 20 includes two side frames 20A and two connecting frames 20B that connect the side frames 20A. As shown in FIG. 3, one side frame 20 </ b> A has one end portion supported by the mast 15 so as to be movable up and down, and the other end portion supported by the mast 16 so as to be movable up and down. The other side frame 20 </ b> A has one end portion supported by the mast 18 so as to be movable up and down, and the other end portion supported by the mast 17 so as to be movable up and down.

  The two connecting frames 20B are provided to connect a pair of side frames 20A that are spaced apart. Accordingly, the lift frame 20 is supported by the masts 15 to 18 and performs a lifting operation.

  Further, the lift frame 20 is configured such that the pallet 19, the pallet transfer device 21, and the turning device 23 are disposed as described above. Further, the lift frame 20 is configured to engage with movable sidewalks 27 and 28 (which will be described later). Therefore, when the lift frame 20 moves up and down, the pallet 19, the pallet transfer device 21, the turning device 23, and the movable sidewalks 27 and 28 also move up and down.

  Here, the passenger compartment 29 will be described with reference mainly to FIG.

  The floor of the passenger compartment 29 is composed of the pallet 19, movable sidewalks 27 and 28, and fixed sidewalks 43 </ b> A to 43 </ b> D. The pallet 19, movable sidewalks 27 and 28, and fixed sidewalks 43 </ b> A to 43 </ b> D are configured to have substantially the same height as shown in FIGS. 1 and 2 when the vehicle 70 enters and exits the passenger compartment 29. ing. Therefore, the passenger can get on and off the vehicle 70 and the passenger can walk safely in the passenger compartment 29. The position of the pallet 19 at this time is referred to as a boarding / alighting position SL.

  The movable sidewalk 27 and the two fixed sidewalks 43A and 43B are arranged side by side in the directions of arrows X1 and X2 on the right side of the pallet 19 in FIG. Specifically, the movable sidewalk 27 is disposed so as to be sandwiched between a pair of fixed sidewalks 43A and 43B.

  Further, the movable sidewalk 28 and the two fixed sidewalks 43C and 43D are arranged side by side in the X1 and X2 directions on the left side of the pallet 19 in FIG. Specifically, the movable sidewalk 27 is arranged so as to be sandwiched between a pair of fixed sidewalks 43C and 43D.

  As described above, in this embodiment, the movable sidewalks 27 and 28 and the fixed sidewalks 43 </ b> A to 43 </ b> D are disposed around the pallet 19, and a wide sidewalk space exists on both sides of the pallet 19. The heights of the pallet 19, the movable sidewalks 27 and 28, and the fixed sidewalks 43A to 43D are substantially equal. For this reason, when the passenger gets on and off the vehicle 70 in the passenger compartment 29, the passenger can get on and off safely and easily.

  On the other hand, the fixed sidewalks 43 </ b> A to 43 </ b> D have legs (not shown) extending downward, and the legs are fixed to the installation surface 13. Further, the positions of the fixed sidewalks 43A to 43D are provided at positions that do not interfere with the lifting operation of the lift frame 20 (20B). Therefore, when the lift frame 20 moves up and down, it does not interfere with the fixed sidewalks 43A to 43D.

  On the other hand, the movable sidewalks 27 and 28 are arranged so as to straddle the connecting frame 20 </ b> B constituting the lift frame 20. As shown in FIGS. 10A and 10B, the movable sidewalks 27 and 28 are configured by a sidewalk surface 81 and a plurality of (for example, four) leg portions 82 extending downward. .

  The sidewalk surface 81 is a surface on which a person walks on the upper surface. Further, unlike the fixed sidewalks 43A to 43D, the leg portion 82 is not fixed to the installation surface 13, so that the movable sidewalks 27 and 28 can move in the up-and-down direction (arrows Z1 and Z2 directions) with respect to the installation surface 13. It is said that.

  Further, the leg portion 82 is configured to engage with a guide roller 85 provided on the lift frame 20 so as to be movable in the ascending / descending direction (arrow Z1, Z2 direction). Therefore, the movable sidewalks 27 and 28 are configured to be movable in the up-and-down direction (arrow Z1 and Z2 directions) within a predetermined range with respect to the lift frame 20 as well. Moreover, even if the movable sidewalks 27 and 28 are lifted from the installation surface 13 together with the lift frame 20 as described later, the movable sidewalks 27 and 28 are detached from the lift frame 20 by engaging the guide rollers 85 with the leg portions 82. And can be reliably prevented from falling.

  Further, a contact member 83 is provided at a position facing the connection frame 20 </ b> B on the back surface of the sidewalk surface 81. As will be described later, the contact member 83 contacts the frame upper surface 20C of the connection frame 20B when the lift frame 20 is raised. When the lift frame 20 is further raised after the contact, the movable sidewalks 27 and 28 are separated from the installation surface 13 and are raised together with the lift frame 20. At this time, the movable sidewalks 27 and 28 are in a state of being suspended from the lift frame 20 (see FIG. 12).

  Next, the pallet turning device 23 for turning the pallet 19 will be described.

  As shown in FIG. 10, the turning device 23 includes a turning base 69, a turning motor 71, and the like. A driven gear 69 a is disposed below the turning base 69, and a driving gear 71 a provided on the rotating shaft of the turning motor 71 is engaged with the driven gear 69 a. Accordingly, when the turning motor 71 is driven, the driven gear 69a is rotated via the drive gear 71a.

  The driven gear 69a is configured integrally with the turning base 69. Therefore, the turning base 69 is turned when the turning motor 71 is driven. In addition, a pallet transfer device 21 on which the pallet 19 is mounted is provided on the upper part of the turning base 69. Therefore, when the turning device 23 is driven and the turning base 69 is turned, the pallet 19 together with the pallet transfer device 21 performs a turning operation with respect to the lift frame 20.

  However, in the state where the height of the pallet 19, the heights of the movable sidewalks 27 and 28, and the heights of the fixed sidewalks 43 </ b> A to 43 </ b> D are substantially equal as shown in FIGS. 1 and 2, It cannot be turned. Therefore, in this embodiment, the pallet 19 is raised to a pallet turning position TL higher than the boarding / alighting position SL shown in FIGS. 1 and 2, and the pallet 19 is turned in this state (this will be described in detail later). ).

  The turning device 23 according to the present embodiment is configured to turn the pallet 19 in units of 90 °. Thereby, the pallet 19 can be turned between the position indicated by the solid line in FIG. 3 and the position indicated by the alternate long and short dash line in FIG. 3 rotated 90 degrees from this position.

  A circle CR indicated by a two-dot chain line in FIG. 3 is a circle drawn by the corners of the four corners of the pallet 19 that is rectangular in plan view when the pallet 19 rotates around the pallet rotation center O. (Hereinafter, this circle is referred to as a pallet rotation circle CR). The diameter of the pallet rotation circle CR is indicated by an arrow D in FIG. 3 (hereinafter, the diameter of the pallet rotation circle CR is referred to as pallet diameter D). The aforementioned masts 15 to 18 are provided outside the pallet diameter D, and are set so as not to obstruct the pallet 19 from turning.

  Next, the pallet transfer device 21 that transfers the pallet 19 between the lift 11 and the parking layer 12 will be described.

  The pallet transfer device 21 is disposed on the turning base 69 of the turning device 23 described above, and the pallet 19 is mounted on the pallet transferring device 21. As the pallet transfer device 21, a transfer device disclosed in Japanese Patent Publication No. 7-29681 filed earlier by the present applicant can be applied.

  In the conveying device disclosed in the publication, driving wheels driven by a motor are arranged at positions corresponding to the four corner positions of the pallet 19. The pallet 19 mounted on the pallet transfer device 21 is moved by driving the drive wheels. Further, the four drive wheels disposed at the four corner positions are configured to be rotated 90 ° by an actuator. Furthermore, the rotation direction of the drive wheel can be performed in either the forward direction or the reverse direction. Therefore, the pallet 19 is configured to be movable in four orthogonal directions by the pallet transfer device 21.

  A specific operation of the pallet transfer device 21 will be described with reference to FIG.

  4 is a view taken along the line BB in FIG. 1, and particularly shows a state in which the pallet 19 (indicated by a two-dot chain line in FIG. 4) is raised to 2F by an elevating device 22 described later. As shown in the drawing, Y-direction pallet guide frames 72 and 73 and X-direction pallet guide frames 74 and 75 are disposed around the lift 11 in 2F of the parking layer 12.

  Each of the guide frames 72 to 75 is provided with a pallet moving roller 34A and a pallet guide roller 34B at appropriate positions. The pallet moving roller 34A is provided with a pallet moving motor 34C, and the pallet moving motor 34C is driven to drive the pallet moving roller 34A so that the pallet 19 is moved.

  In the state shown in FIG. 4, the pallet transfer device 21 drives the pallet 19 to move in the direction of the arrow Y2, and the pallet moving roller 34A provided on the pallet guide frame 72 for Y direction similarly moves the pallet 19. When driven to move in the arrow Y2 direction, the pallet 19 is transferred from the lift 11 to the Y-direction pallet guide frame 72 by the pallet transfer device 21 or the like.

  On the contrary, when the pallet 19 is mounted on the Y-direction pallet guide frame 72 as shown by a two-dot chain line in FIG. 1 (in FIG. 1, two points indicate that the vehicle 70 is mounted on the pallet 19. The pallet moving roller 34A provided on the Y-direction pallet guide frame 72 similarly drives the pallet 19 to move in the arrow Y1 direction, and the pallet transfer device 21 similarly causes the pallet 19 to move. , The pallet 19 is transferred from the Y-direction pallet guide frame 72 to the lift 11 by the pallet transfer device 21 and the like.

  The transfer operation described above is performed between the pallet transfer device 21 and the Y-direction pallet guide frame 73 (transfer directions are Y1 and Y2 directions), and between the pallet transfer device 21 and the X-direction pallet guide frame 74. (Transfer direction is X1, X2 direction) and between the pallet transfer device 21 and the X direction pallet guide frame 75 (transfer direction is X1, X2 direction).

  Therefore, the pallet 19 is arranged between the pallet transfer device 21 and the Y direction pallet guide frame 72, between the pallet transfer device 21 and the Y direction pallet guide frame 73, and between the pallet transfer device 21 and the X direction pallet. It is possible to transfer between the guide frame 74 and between the pallet transfer device 21 and the X direction pallet guide frame 75.

  Thus, in the mechanical parking lot 10 which concerns on a present Example, since it is the structure which can transfer the pallet 19 to the four directions to which the pallet transfer apparatus 21 orthogonally crosses, between the lift 11 and the parking layer 12, it is orthogonal. The pallet 19 can be transferred in the four directions. In addition, when the pallet 19 is transferred between the lift 11 and the parking layer 12, the arrangement positions of the masts 15 to 18 are set at positions that do not get in the way.

  Next, mainly with reference to FIGS. 5 to 9, various apparatuses and devices for raising and lowering the pallet 19 will be described.

  In the present embodiment, the pallet 19 is moved up and down using the lifting device 22, the first and second counterweights 30, 31, the annular chains 37 to 40, the connecting chains 41 and 42, the sprockets 45 to 52, and the like. Yes.

  FIG. 5 is a diagram schematically showing various devices for raising and lowering the pallet 19 applied in the present embodiment. As shown in the figure, annular chains 37 to 40 are connected to the four corner positions of the lift frame 20 (shown in FIG. 5 as a single plate for convenience of illustration).

  Each annular chain 37-40 has a configuration in which the upper part is wound (meshed) on the first gears 45A, 47A, 49A, 51A and the lower part is wound (meshed) on the sprockets 46, 48, 50, 52. Has been. The annular chains 37 to 40 are connected to the lift frame 20 at intermediate positions between the first gears 45A, 47A, 49A, 51A and the sprockets 46, 48, 50, 52.

  The first gears 45A, 47A, 49A, 51A are disposed on the ceiling beam 25, and the sprockets 46, 48, 50, 52 are disposed on the lifting device 22 as described later. Accordingly, the lift frame 20 is configured such that the four corner positions are supported by the four annular chains 37 to 40.

  Next, the first and second counterweights 30 and 31 will be described.

  The first and second counterweights 30 and 31 are based on the total weight of the pallet 19 that is raised and lowered, the lift frame 20, the pallet transfer device 21 and the like (hereinafter referred to as lift frame and the like) and have a weight corresponding thereto. Is set. The gravity of the first and second counterweights 30 and 31 is configured to act on the lift frame 20 in the direction opposite to the weight direction of the lift frame or the like using the sprockets 45 to 51.

  Here, paying attention to the position of the lift frame 20 on the Y1 direction side, the annular chain 39, 40 disposed on the Y1 direction side of the lift frame 20 in the figure is provided with the first counterweight 30 in the middle position thereof. It has been configured. Accordingly, the gravity of the first counterweight 30 is transmitted to the lift frame 20 via the first gear 49A and the first gear 51A, and the acting force acts in the opposite direction to the gravity of the lift frame 20. As a result, the weight of the lift frame 20 is offset by the weight of the first counterweight 30 at the position (one side portion) on the Y1 direction side of the lift frame 20.

  On the other hand, attention is paid to the position on the Y2 direction side of the lift frame 20 (the other side portion opposite to the one side portion) that is separated from the one side portion. The annular chains 37 and 38 disposed on the other side portions are configured such that the counterweight 30 is not provided in the middle thereof. However, in this embodiment, the second counterweight 31 is disposed on one side where the first counterweight 30 is disposed, and the other side of the lift frame 20 and the second counterweight 31 are connected. The chain 41 and 42 are used for connection.

  Specifically, one end portions (right end portions in FIG. 5) of the connecting chains 41 and 42 are connected to the lift frame 20 on the Y2 direction side (connection points are indicated by P in the figure). The connecting chains 41 and 42 extend upward from the connection point P, are then changed in direction by the second gears 45B and 47B, extend in the Y1 direction, and are further extended downward by the second gears 49B and 51B. Is converted and connected to the second counterweight 31.

  With this configuration, the gravity of the second counterweight 31 is transmitted to the position P of the lift frame 20 via the second gears 49B, 51B, 45B, 47B, and the acting force is the gravity of the lift frame 20. Acts in the opposite direction. As a result, the weight of the lift frame 20 is offset by the weight of the second counterweight 31 also at the Y2 direction side position (the other side portion) of the lift frame 20.

  Thereby, the lift frame 20 can be balanced in a horizontal state, and the stable raising / lowering operation | movement of the pallet 19 can be implement | achieved. Further, since the weight of the lift frame 20 is offset by the weights of the first and second counterweights 30 and 31, the output of the lifting device 22 described later can be reduced.

  In the present embodiment, the first counterweight 30 and the second counterweight 31 are collectively disposed on one side of the lift 11 (specifically, the lift housing 36). At the position where the counterweight is disposed, it is necessary to consider that the counterweight does not interfere with the vehicle 70 that enters and exits. However, by arranging the plurality of counterweights 30 and 31 collectively on one side as in this embodiment, it is possible to reduce the number of places where consideration is given to the vehicle 70 entering and leaving.

  Furthermore, in the present embodiment, the first counterweight 30 and the second counterweight 31 are independent from each other. Therefore, the elongation of the annular chains 39 and 40 connected to the first counterweight 30 and the extension of the connecting chains 41 and 42 connected to the second counterweight 31 can be adjusted separately, and the lift Even if a difference in elongation occurs in each chain 39 to 42 over time due to a difference in weight between the front and rear of the frame 20, this can be easily absorbed on the counterweights 30 and 31 side. Can be kept level.

  FIG. 6 shows an enlarged view of the first counterweight 30 and the second counterweight 31. In FIG. 6, about the left half of each counterweight 30, 31 is shown.

  As is clear from the above description, the first counterweight 30 has the annular chain 40 connected to the upper part thereof and the annular chain 40 also connected to the lower part thereof. The annular chain 40 located at the lower part is inserted into a through hole 79 formed in the second counterweight 31 and extends below the second counterweight 31.

  The second counterweight 31 is arranged side by side at the lower part of the first counterweight 30, and a connecting chain 42 is connected to the upper part. A guide protrusion 76 is formed on the outer side of the first counterweight 30 described above, and a guide groove 77 is formed at a position of the second counterweight 31 facing this. The guide groove 77 extends long in the vertical direction (Z1, Z2 direction), and the guide protrusion 76 is configured to be movably engaged with the guide groove 77. Thereby, when the 1st counterweight 30 and the 2nd counterweight 31 move to an up-down direction, it can prevent that it mutually interferes and a collision generate | occur | produces between both.

  A guide roller 78 is provided on the outer side of the second counterweight 31. The guide roller 78 is configured to engage with the mast 17 and the mast 18. Therefore, the first and second counterweights 30 and 31 are guided by the masts 17 and 18 and move up and down. Therefore, the first and second counterweights 30 and 31 are moved smoothly.

  Further, a clearance 35 is formed between the first counterweight 30 and the second counterweight 31. For this reason, even if elongation occurs in each chain 37 to 42, it is possible to immediately prevent the counterweights 30 and 31 from interfering with each other, thereby preventing noise and damage to the counterweights 30 and 31. Can do.

  7 and 8 show enlarged positions of the sprockets 45 to 51 (in FIG. 7, only the sprockets 45 and 49 are shown). As shown in the drawings, the sprockets 45 to 51 are disposed on the ceiling beam 25 supported by the masts 15 to 18. For this reason, although the connection chains 41 and 42 receive the gravity of the lift frame 20 and the counterweights 30 and 31 which are heavy objects, they can be reliably received.

  In the present embodiment, it is necessary to route the connecting chains 41 and 42 from the position P of the lift frame 20 (see FIG. 5) to the second counterweight 31. However, since the connection chains 41 and 42 are routed using the upper part of the ceiling beam 25, the connection chains 41 and 42 do not interfere with other configurations.

  Furthermore, the first gear 45A and the second gear 45B are arranged coaxially. Similarly, the first gear 47A and the second gear 47B are arranged coaxially. That is, the first gears 45A, 47A, 49A, 51A and the second gears 45B, 47B, 49B, 51B are arranged coaxially as shown in FIG. In this embodiment, the connecting chains 41 and 42 are provided in addition to the annular chains 37 to 40, but sprockets 45 to 51 in which the first gear and the second gear are arranged coaxially as shown in FIG. 8 are used. Thereby, the compact arrangement | positioning of each chain 37-42 can be performed.

  FIG. 9 shows the lifting device 22. As shown in FIGS. 1 and 2, the lifting device 22 is disposed at the lower portion of the lift frame 20. The lifting device 22 is configured such that a motor 60, drive shafts 64 and 65, speed reducers 62 and 63, connecting shafts 66A, 66B, 67A, and 67B are disposed on a frame 61.

  The motor 60 is a motor that can output in both the front and rear directions. One output shaft is connected to the drive shaft 64, and the other output shaft is connected to the drive shaft 65. The drive shaft 64 is connected to the speed reducer 62. The speed reducer 62 decelerates the rotation of the motor 60 and outputs it as the rotational force of the connecting shafts 66A and 66B. Similarly, the drive shaft 65 is connected to the speed reducer 63. In the speed reducer 63, the rotation of the motor 60 is decelerated and output as the rotational force of the connecting shafts 67A and 67B.

  The connection shaft 66A is provided with a sprocket 46 at the end opposite to the end connected to the speed reducer 62. The sprocket 46 is wound with the annular chain 37 as described above. The connection shaft 66B is provided with a sprocket 48 at the end opposite to the end connected to the speed reducer 62. The sprocket 48 is wound with the annular chain 38 as described above.

  The connecting shaft 67A is provided with a sprocket 50 at the end opposite to the end connected to the speed reducer 63. The sprocket 50 is wound with the annular chain 39 as described above. The connecting shaft 67B is provided with a sprocket 52 at the end opposite to the end connected to the speed reducer 63. The sprocket 52 has the annular chain 40 wound thereon as described above.

  Accordingly, when the motor 60 is driven, the sprockets 46, 48, 50, 52 are rotated via the drive shafts 64, 65, the speed reducers 62, 63, and the connecting shafts 66A, 66B, 67A, 67B. The circular chains 37 to 40 are urged to rotate. Thereby, the lift frame 20 connected to the annular chains 37 to 40 is raised and lowered, and the pallet 19 mounted on the lift frame 20 is also raised and lowered accordingly.

  Next, a procedure for warehousing the vehicle 70 loaded on the pallet 19 into the parking layer 12 will be described.

  In the following description, due to the installation space of the mechanical parking lot 10, the direction of entry of the vehicle 70 into the passenger compartment 29 is limited to the X2 direction (see FIG. 13B), and the 2F parking layer. 12, an example (see FIG. 13C) in which the pallet 19 is stored so that its longitudinal direction is the Y1, Y2 direction will be described.

  FIG. 13B shows a state where the vehicle 70 is stored in the passenger compartment 29. As described above, since the warehousing direction of the vehicle 70 is limited to the X2 direction, the pallet 19 of the passenger compartment 29 is set so that the longitudinal direction is the X1 and X2 directions at the time of warehousing.

  Further, when the vehicle 70 enters the passenger compartment 29, the lift frame 20 is at the lowest position by the lifting device 22. FIG. 10 shows a state where the lift frame 20 is in the landing position. The position of the lift frame 20 at this time is referred to as a landing position.

  At this time, the distance between the installation surface 13 and the frame upper surface 20C of the connecting frame 20B is the distance indicated by the arrow H1 in FIG. 10A, and the frame upper surface 20C and the abutment provided on the movable sidewalks 27 and 28. The distance from the member 83 is ΔH. That is, when the lift frame 20 is located at the landing position, a gap ΔH is formed between the frame upper surface 20C and the contact member 83 (movable sidewalks 27 and 28). In the state where the lift frame 20 is located at the landing position, the pallet 19, the movable sidewalks 27 and 28, and the fixed sidewalks 43 </ b> A to 43 </ b> D are located at the getting-on / off position SL, and thus have substantially the same height.

  In the state where the lift frame 20 is located at the landing position as described above, the vehicle 70 enters the passenger compartment 29 and is loaded on the pallet 19. At this time, as described above, the pallet 19, the movable sidewalks 27 and 28, and the fixed sidewalks 43 </ b> A to 43 </ b> D have the same height. Can get off and walk in the passenger compartment 29 safely and smoothly.

  When the vehicle 70 is loaded on the pallet 19 and the passenger leaves the passenger compartment 29, the process of moving the vehicle 70 to the parking layer 12 is started. As described above, in the case of the present embodiment, the storage direction of the pallet 19 in the parking layer 12 is the Y1, Y2 direction, while the storage direction of the vehicle 70 with respect to the passenger compartment 29 is X1, X2. It is. Therefore, it is necessary to turn the pallet 19 by 90 ° in the passenger compartment 29 or in a state where the pallet 19 is raised to 2F.

  In this embodiment, in the configuration in which the pallet 19 is rotated by 2F, it is necessary to provide a swirl space on 2F and the space efficiency is poor. However, the turning position of the pallet 19 is not limited to the passenger compartment 29 and may be provided in the parking layer 12 depending on the installation height condition of the mechanical parking lot 10.

  As described above, the pallet 19 is turned using the turning device 23. However, when the lift frame 20 is located at the landing position, the height of the pallet 19, the movable sidewalks 27 and 28, and the fixed sidewalks 43 </ b> A to 43 </ b> D are substantially equal. It interferes with each sidewalk 27, 28, 43A-43D, and cannot turn.

  Therefore, in this embodiment, when the pallet 19 is turned, the lift 11 is activated to raise the lift frame 20 to a position where the pallet 19 can turn. Specifically, the lifting device 22 constituting the lift 11 is activated to rotate the sprockets 46, 48, 50 and 52, thereby moving the annular chains 37 to 40, thereby raising the lift frame 20. Note that the position of the lift frame 20 in a state where the pallet 19 can turn is referred to as a turnable position.

  FIG. 11 shows a state in which the lift frame 20 has been raised to the turnable position. As described above, when the lift frame 20 is raised to the pivotable position, the lifting device 22 is stopped once, and thus the lift frame 20 is also stopped.

  In this state, the height of the frame upper surface 20C from the installation surface 13 is the height indicated by the arrow H2 in FIG. As the lift frame 20 moves to the turnable position in this way, the pallet 19 rises from the boarding / alighting position SL and rises to a pallet turn position (a position indicated by TL in FIG. 11) at which the pallet 19 can turn. .

At this time, the lift frame 20 is located at the landing position for the lift distance H _D (H _D = H2−H1) where the lift frame 20 rises before the pallet 19 rises from the boarding / alighting position SL to the pallet turning position TL. Is set to be smaller than the gap ΔH between the frame upper surface 20C and the contact member 83 (ΔH> H _D ). That is, when the lift frame 20 moves up and down between the landing position and the turnable position, the lift frame 20 is configured to move within the height range of the gap ΔH.

  With this configuration, even when the lift frame 20 moves up and down, the movable sidewalk 27 maintains the state of landing on the installation surface 13 (boarding position SL), and the pallet 19 and the like disposed on the lift frame 20 can be maintained. Only the composition can be raised.

  When the pallet 19 rises to the pallet turning position TL, the turning device 23 is activated to rotate the pallet 19 by 90 °. Thereby, the pallet 19 is in a state in which the longitudinal direction is along the Y1 and Y2 directions.

  When the turning process of the pallet 19 is completed as described above, the lifting device 22 is activated again and the lift frame 20 starts to rise. As the lift frame 20 rises, the frame upper surface 20C eventually comes into contact with the contact member 83 provided on the movable sidewalks 27 and 28. When 20 further rises, the movable sidewalks 27 and 28 are engaged with the lift frame 20 (specifically, the movable sidewalks 27 and 28 are placed so as to straddle the lift frame 20).

  Therefore, the lift of the lift frame 20 thereafter is performed in a state where the movable sidewalks 27 and 28 are placed. FIG. 12 shows a state where the lift frame 20 is lifted with the movable sidewalks 27 and 28 placed thereon, and shows a state where the height of the frame upper surface 20C from the installation surface 13 is H3 (H3). > H1 + ΔH).

  As described above, when the lift frame 20 rises from the swivelable position, the lift frame 20 rises with the movable sidewalks 27 and 28 placed thereon. As described above, the leg portions 82 of the movable sidewalks 27 and 28 are lifted. The movable sidewalks 27 and 28 do not move on the lift frame 20 or drop off from the lift frame 20 because the guide rollers 85 provided at 20 are engaged. Further, when the lift frame 20 is raised, the pallet 19 and the movable sidewalks 27 and 28 are raised while maintaining a state where they are separated by a distance indicated by an arrow H4 in FIG.

  Eventually, the lift frame 20 is located at a position where the pallet 19 can be transferred with respect to the Y-direction pallet guide frames 72 and 73 and the X-direction pallet guide frames 74 and 75 provided on the second floor of the parking layer 12 (hereinafter referred to as the lift frame 20). This height position is called a transferable position). When the lift frame 20 is raised to the transferable position, the lifting device 22 is stopped and the lift frame 20 is positioned at the transferable position.

  FIG. 4 shows a state where the lift frame 20 is positioned at the transferable position. In this state, the height of the pallet 19 corresponds to the height of each of the pallet guide frames 72 to 75 provided on the parking shelf installation slab 33 (see FIGS. 1 and 2). Further, as described above, the lift 11 is provided with the pallet transfer device 21 capable of transferring the pallet 19 in four directions orthogonal to each other, and on each pallet guide frame 72 to 75 disposed on the second floor of the parking layer 12. A pallet moving roller 34A and a pallet guide roller 34B are provided.

  Therefore, according to the mechanical parking lot 10 according to the present embodiment, between the pallet transfer device 21 and the Y direction pallet guide frame 72, between the pallet transfer device 21 and the Y direction pallet guide frame 73, The pallet 19 can be transferred between the pallet transfer device 21 and the X direction pallet guide frame 74 and between the pallet transfer device 21 and the X direction pallet guide frame 75.

  Thus, since the mechanical parking lot 10 according to the present embodiment can transfer the pallet 19 in four directions orthogonal to each other between the lift 11 and the parking layer 12, the mechanical parking lot 10 is installed. When doing, the freedom degree of the layout of the lift 11 and the parking layer 12 can be raised.

  Further, the pallet transfer device 21 mounted on the lift 11 is not necessarily limited to the four-way transfer. For example, when the lift 11 is provided at a position indicated by reference numeral 11A in FIG. Can be used as a lift for two-way transfer, and when the lift 11 is provided at a position indicated by reference numeral 11B, the lift 11 can be used as a lift for three-way transfer.

  Furthermore, the mechanical parking lot 10 according to this embodiment moves the movable sidewalks 27 and 28 up and down relatively with respect to the pallet 19 using the lift frame 20 and the lifting device 22 provided in the lift 11. Therefore, it is not necessary to provide a new driving device for moving the movable sidewalks 27 and 28, and the cost of the mechanical parking lot 10 can be reduced.

  In the above-described embodiment, an example in which the transport device disclosed in Japanese Patent Publication No. 7-29681 is applied as the pallet transfer device 21 is shown, but the pallet transfer device 21 is not limited to this. As long as the pallet 19 can be rotated, other transfer devices can be used.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific embodiments described above, and various modifications can be made within the scope of the present invention described in the claims. It can be modified and changed.

  Specifically, the present invention can be applied to a mechanical parking lot that does not have a turning device, and the pallet is orthogonally crossed between the lift and the parking layer without having a turning device. Can be transferred in four directions.

  In this embodiment, the pallet is turned by 90 °. However, the pallet can be turned by 180 °. In this configuration, there is no need to provide a movable sidewalk.
