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

  FIG. 1 is a side view showing a schematic configuration of a mechanical parking apparatus according to an embodiment of the present invention.

  The driver of the parked vehicle enters the parked vehicle from the entrance / exit formed in the entrance / exit floor of the underground parking device building 1 and gets on the tray 3 mounted on the lift device 2, and then gets off the parked vehicle and parks the parked vehicle. To the mechanical parking device. Then, while being controlled by the control device, the lift device 2 transports the parked vehicle to the storage unit floor that is configured in the basement, etc., and after lowering from the lift device 2, it is moved to an arbitrary parking space on the storage unit floor. At the same time, the parked vehicle is stored. Although various configurations can be adopted for the storage unit floor, a storage unit having a multilayer structure is illustrated here, and a plurality of pillars 4A to 4N are used to form the uppermost layer floor 5, the middle layer floor 6 and The lowermost layer floor 7 is supported and fixed to form a three-layer structure of an uppermost layer portion 8, an intermediate layer portion 9 and a lowermost layer portion 10.

  As will be described in detail later, a tray-side guide rail is formed on the back side of the tray 3, while a tray is driven in each storage space of the uppermost floor 5, the intermediate floor 6 and the lowermost floor 7. A floor side tray driving device is configured. The floor side tray driving device has a direction changing function for changing the direction. The direction changing function is used to change the direction of the movable guide rail, and the tray driving is performed based on a command from a control device (not shown). The tray 3 can be moved to a storage space at an arbitrary position by the apparatus.

  The lift device 2 that moves the parked vehicle between the entrance floor and each of the layer portions 8 to 10 is arranged along a pair of vertical guide rails 11 that are fixed to be opposed to the front side and the back side of the sheet, and the vertical guide rails 11. It is configured to include a lift 12 that can move up and down and can mount a tray 3 on which a parked vehicle can be mounted, and a lift drive device (not shown) that drives the lift 12 up and down. ing.

  In the present embodiment, among the uppermost layer portion 8, the intermediate layer portion 9 and the lowermost layer portion 10 of the three-layer structure, the uppermost layer portion 8 positioned at the uppermost position is a large tray 3A on which a large vehicle such as a high roof can be mounted. And a small tray 3B on which small and medium-sized vehicles can be mounted. On the other hand, the intermediate layer portion 9 and the lowermost layer portion 10 are configured so that only small trays 3B on which small and medium-sized vehicles can be mounted can be stored.

  In order to use such two types of large trays 3A and small trays 3B, even if the large tray 3A is mounted on the lift device 2 on the floor near the entrance / exit of the underground parking apparatus building 1 A lift opening 13 having a size that can be pulled in even with the small tray 3B is formed. Naturally, the size of the lift opening 13 is determined in consideration of the size of the large tray 3A. Therefore, when the small tray 3B is used, the outer periphery of the small tray 3B and the lift opening 13 are included. A gap is formed between the peripheral portions, and the safety of the feet is impaired when the driver gets off the parked vehicle. Therefore, a shielding device 14 that shields the gap only when the small tray 3B is used will be described later.

  FIG. 2 is a plan view showing the intermediate layer portion 9.

  In this embodiment, the positions of the pillars 4A to 4N and the size of the small tray 3B are the same as those of the mechanical parking apparatus when it is not assumed that the large tray 3A on which a large vehicle such as a high roof can be mounted. The plurality of columns 4A to 4N used to form the uppermost layer portion 8, the intermediate layer portion 9, and the lowermost layer portion 10 of the three-layer structure are used when the small tray 3B moves in the longitudinal direction or the width direction shown in the figure. Each is installed in a position where it will not interfere. For example, the distance between the pillar 4C and the pillar 4D, and between the pillar 4G and the pillar 4H is slightly larger than the width of the small tray 3B, and does not restrict the movement of the small tray 3B in the longitudinal direction. Similarly, the distance between the pillar 4C and the pillar 4G, and between the pillar 4D and the pillar 4H is slightly larger than the length of the small tray 3B, and does not restrict the movement of the small tray 3B in the width direction.

  Here, three rows of storage spaces are formed in the illustrated horizontal direction, and three rows of storage spaces are also formed in the vertical direction. The intermediate layer floor 6 shown in FIG. 1 forming each storage space has a floor-side longitudinal guide rail 15A and a floor-side width direction guide rail for guiding the movement of the small tray 3B in the longitudinal direction and the width direction. Each of the floor side tray driving devices 16 including 15B is configured.

  At least one of the storage spaces is an empty space in which the small tray 3B is not disposed. By moving the small tray to this empty space, an empty space is formed in the moving direction of the predetermined small tray, and this operation is repeated. Thus, the predetermined small tray 3B is controlled to move to a predetermined position.

  In this embodiment, the lowermost layer portion 10 shown in FIG. 1 is not shown, but has the same configuration as the intermediate layer portion 9.

  FIG. 3 is a plan view showing the uppermost layer portion 8.

  Each of the pillars 4A to 4N described above is established from the lowermost layer portion 10 shown in FIG. 1 and extends upward, but extends to the vicinity of the uppermost layer portion floor 5 in the uppermost layer portion 8, and the uppermost layer portion floor. 5 does not hinder the movement of the large tray 3A and the small tray 3B. Therefore, even in the mechanical parking device in which the intermediate layer portion 9 and the lowermost layer portion 10 are configured using the pillars 4A to 4N arranged at the same intervals as the conventional configuration, if the uppermost layer portion 8 is selected, the uppermost layer portion 8 The size of the large tray 3A is not limited by the interval between the pillars 4A to 4N. In this way, in the uppermost layer portion 8, a large tray 3A larger than the small tray 3B can be used, and the large tray 3A and the small tray 3B can be easily mixed as shown in FIG.

  In addition, the large tray 3A is larger than the small tray 3B and longer than the small tray 3B within the range in which the large tray 3A can move without colliding with each other even when arranged in the adjacent storage spaces. Can also be configured with a large length. For example, in the storage space corresponding to the pillars 4C, 4D, 4G, and 4H shown in FIG. 2, a large tray 3A that is slightly smaller than a virtual rectangle that connects the center lines of the pillars 4C, 4D, 4G, and 4H is used. It becomes possible to do.

  Also in the uppermost layer portion 8, three rows of storage spaces are formed in the illustrated longitudinal direction, and three rows of storage spaces are also formed in the width direction. The floor-side longitudinal guide rail 15A and the floor-side width direction for guiding the movement of the large tray 3A and the small tray 3B in the longitudinal direction and the width direction are also provided on the floor of the uppermost layer portion 8 forming these storage spaces. While having the guide rail 15B, the floor side drive device 16 of the same structure as what was shown in FIG. 2 is each comprised. The floor-side tray driving device 16 constitutes a driving device that drives the large tray 3A and the small tray 3B to an arbitrary storage space via a tray-side guide rail described later in the uppermost layer portion 8.

  FIG. 4 is a plan view showing the tray-side guide rail.

The large tray 3A and the small tray 3B are different in size, but basically have the tray side guide rail having the same configuration , so here the tray side guide rail configured on the back side of the large tray 3A. Will be described.

  On the back surface of the large tray 3A, longitudinal wheels 17A to 17D that support the large tray 3A so as to travel along the floor-side longitudinal guide rail 15A, and the large tray 3A along the floor-side width direction guide rail 15B. The width direction wheels 18 </ b> A to 18 </ b> D supported so as to travel are rotatably attached. Further, on a straight line 19 extending in the longitudinal direction at the center portion, fixed guide rails 19A, 19B, and 19C that are discretely fixed, and a movable guide rail 20A that is disposed between the opposing portions of these fixed guide rails 19A to 19C. , 20B are provided. These movable guide rails 20A and 20B are rotatably supported around the central axes 21A and 21B, respectively. Further, when the movable guide rails 20A and 20B are rotated 90 degrees and faced in the width direction, the other fixed guide rails 23A and 23B are placed on the width direction straight lines 22A and 22B that coincide with the movable guide rails 20A and 20B. The fixed guide rails 24A and 24B are fixed correspondingly.

  Therefore, in the state where the movable guide rails 20A and 20B face the longitudinal direction as shown in the drawing, the fixed guide rails 19A to 19C and the movable guide rails 20A and 20B are positioned on the straight line 19 in the longitudinal direction. On the other hand, in a state where the movable guide rails 20A and 20B face the width direction, the fixed guide rails 23A and 23B and the movable guide rail 20A are positioned on the width direction straight line 22A, and the fixed guide rails 24A and 24B and the movable guide rail 20B. Are positioned on the width direction straight line 22B.

  FIG. 5 is a plan view showing the floor-side tray driving device 16 configured on the floor side of each storage space described above.

  The floor side tray drive device 16 is configured on a base 25 fixed to the floor surface for each storage space. A first drive device 27 rotatably provided by a rotary shaft 26 provided at a position substantially opposite to the central axis 21A shown in FIG. 4, and a rotation provided at a position substantially opposite to the central axis 21B shown in FIG. A second drive device 29 that is rotatably provided by a shaft 28, and a switching drive device 30 that is located in an intermediate portion between the first drive device 27 and the second drive device 29 and switches the rotation angle of the rotary shafts 26 and 28. have.

  The switching drive device 30 has a lever 33 that is rotated by a motor 32 around a rotation shaft 31, and a link 34 connected to one end of the lever 33 is connected to the rotation shaft 26 of the first drive device 27. It is connected to a fixed arm 35. The link 36 connected to the other end of the lever 33 is connected to an arm 37 fixed to the rotary shaft 28 of the second drive device 29.

  The first driving device 27 sandwiches the motor 38, the feed roller 39 that is a friction roller that is rotationally driven by the motor 38, and the movable guide rail 20 </ b> A that is located on both sides of the rotating shaft 26. Two sets of sandwiching rollers 40 arranged opposite to each other are provided. The second drive device 29 has the same configuration, and sandwiches the above-described movable guide rail 20 </ b> B located on both sides of the rotation shaft 28 and the motor 41, the feed roller 42 that is a friction roller that is rotationally driven by the motor 41. Two pairs of sandwiching rollers 43 are provided so as to face each other.

  When the motors 38 and 41 are rotated in the illustrated state, the feed rollers 39 and 42 are also rotated. The feed rollers 39 and 42 are pressed against the fixed guide rails 19A, 19B, and 19C shown in FIG. 4 of the large tray 3A disposed in the same storage space, and the rotational force is applied to the straight line 19 in the longitudinal direction. For example, the large tray 3A is moved upward in the drawing. On the other hand, when the motors 38 and 42 are rotated in the reverse direction, the large tray 3A is moved downward along the longitudinal straight line 19 by the reverse rotational force of the feed rollers 39 and 42.

  However, when the lever 33 is rotationally driven counterclockwise by a predetermined angle by the motor 32 of the switching drive device 30, the first drive device 27 connected via the link 34 is 90 degrees counterclockwise about the rotary shaft 26. And the second driving device 29 connected via the link 36 is rotated by 90 degrees counterclockwise about the rotation shaft 28. Due to the above-described rotation of the first driving device 27 and the second driving device 29, the movable guide rails 20A and 20B of FIG. 4 sandwiched between the sandwiching rollers 40 and 43 are also rotated by 90 degrees. In this state, when the feed rollers 39 and 42 are rotated by the motors 38 and 41, the large tray 3A shown in FIG. 4 is moved along the width direction straight lines 22A and 22B, for example, to the left as shown. .

  On the other hand, when the feed rollers 39 and 42 are rotated in the reverse direction by the motors 38 and 41, the large tray 3A shown in FIG. 4 is now moved in the right direction along the width direction straight lines 22A and 22B. I will let you.

  Such a floor-side tray driving device 16 is configured on the floor side for each storage space, and each tray-side guide rail is configured for each of the large tray 3A and the small tray 3B, whereby a predetermined large tray 3A or small tray 3B. Can be moved to a predetermined storage space. That is, the motors 32, 38, and 41 in the floor side tray drive device 16 provided on the lower floor of the predetermined large tray 3A are controlled from the control device while using at least one empty space existing in the storage space. By doing so, the predetermined large tray 3A is moved to the adjacent empty space. Thereafter, the same is applied, and the predetermined large tray 3A is sequentially moved by controlling the motors 32, 38, 41 in the floor-side tray driving device 16 newly corresponding to the moved position from the control device while using the empty space. Thus, it can finally be moved to a predetermined storage space in a self-supporting manner.

  6 and 7 are a plan view and a side view of the lift opening 13 when the large tray 3A is arranged.

  Since the lift opening 13 is formed in a size corresponding to the large tray 3A, when the large tray 3A is placed on the lift device 2 as shown in FIG. 6, the lift opening 13 is substantially blocked by the large tray 3A. It will be in a peeled state. For this reason, when the large tray 3A is prepared on the lift device 12, the detection device (not shown) does not drive the shielding device 14 in the same state, and maintains a substantially vertical non-shielding state. Therefore, as can be seen from both figures, the safety of the feet is ensured when the driver gets off the large parked vehicle after mounting the large parked vehicle on the large tray 3A.

  8 and 9 are a plan view and a side view of the lift opening 13 when the small tray 3B is arranged.

  In this embodiment, the small tray 3B is smaller than the large tray 3A in both the longitudinal direction and the width direction. For this reason, as shown in both figures, when the small tray 3B is placed on the lift device 2, gaps are formed between the four directions of the outer periphery of the small tray 3B and the inner edge of the lift opening 13 respectively. In this state, after the small parking vehicle is mounted on the small tray 3B, there is a risk that when the driver gets off from the small parking vehicle, the foot falls in a gap existing under the foot and falls.

  However, as shown in both figures, the shielding device 14 is arranged on the outer periphery of the lift opening 13, and when the small tray 3B is prepared on the lift device 2, a detection device (not shown) detects the same state, The shielding device 14 is driven so that the gap formed between the four directions of the outer periphery of the small tray 3B and the inner edge of the lift opening 13 is in a shielding state. The shielding device 14 is driven from the vertical non-shielding state shown in FIG. 7 to the substantially horizontal shielding state shown in FIG. Thus, the gap that exists between the four directions of the outer periphery of the small tray 3B and the inner edge of the lift opening 13 is closed by the shielding device 14 as shown by the hatched lines in FIG. For this reason, when the driver gets out of the small parked vehicle, there is no risk that the driver falls into the gap and falls or is caught in the gap.

  10 and 11 are a plan view and a side view of the lift opening 13 when another small tray 3B is arranged.

  In this embodiment, the small tray 3B is substantially the same size as the large tray 3A in the longitudinal direction, but is smaller than the large tray 3A in the width direction. For this reason, as shown in both figures, when the small tray 3B is placed on the lift device 2, a gap is formed between both sides in the width direction of the small tray 3B and the inner edge of the lift opening 13. As in the previous case, after mounting a small parked vehicle on the small tray 3B, when the driver gets off from the small parked vehicle, the foot is taken down by a gap existing under the foot, or is fallen or pinched There is danger.

  However, when the shielding devices 14 are arranged on both sides of the lift opening 13 in the width direction, and the small tray 3B is prepared on the lift device 2, the detection device (not shown) detects the same state, and the width of the small tray 3B. The shielding device 14 is driven so that both gaps formed between both sides in the direction and the inner edge of the lift opening 13 are in a shielding state. The shielding device 14 is driven from the vertical non-shielding state shown in FIG. 7 to the substantially horizontal shielding state shown in FIG. Thus, both gaps existing between the width direction both sides of the small tray 3B and the inner edge portion of the lift opening 13 are respectively closed by the shielding device 14 as shown by hatching in both drawings. When the driver gets out of the car, there is no risk of the driver falling over and getting caught in the gap.

  Further, the small tray 3B has the same length as that of the large tray 3A in the longitudinal direction, so that there is less space between the outer periphery of the small tray 3B and the inner edge of the lift opening 13, and the shielding device 14 The configuration can be simplified.

  12 and 13 are a plan view and a side view of the lift opening 13 when a small tray 3B having still another configuration is arranged.

  In this embodiment, the small tray 3B is approximately the same size as the large tray 3A in the width direction, but is configured to be as small as the small tray 3B shown in FIG. 8 in the longitudinal direction. For this reason, when the small tray 3B is placed on the lift device 2 as shown in both figures, no gap is formed between the widthwise sides of the small tray 3B and the inner edge of the lift opening 13, but the small tray 3B A gap is formed only between both sides in the longitudinal direction and the inner edge of the lift opening 13.

  However, the shielding device 14 is disposed between the longitudinal direction both sides of the lift opening 13 and the inner edge of the lift opening 13, and the detection device (not shown) is the same when the small tray 3B is prepared on the lift device 2. The state is detected, and the shielding device 14 is driven so as to shield both gaps formed on both sides in the longitudinal direction of the small tray 3B. The shielding device 14 in this case also operates from a substantially vertical non-shielding state as shown in FIG. 7, and becomes a substantially horizontal shielding state as shown in FIG. In this way, the gaps that existed on both sides in the longitudinal direction of the small tray 3B are respectively closed by the shielding device 14 as shown by the oblique lines in both figures. Therefore, when the driver gets out of the small parked vehicle, the driver There is no risk of falling and being caught.

  Further, as the small tray 3B, the same as the large tray 3A in the width direction, the gap area existing between the outer periphery of the small tray 3B and the inner edge of the lift opening 13 is reduced, and the shielding device 14 The configuration can be simplified.

  As can be seen from the description of each of these drawings, there is a restriction that the large tray 3A can be moved between storage spaces without colliding with the small tray 3B, but the size of the large tray 3A or the small tray 3B is limited to some extent. It can be arbitrarily determined.

  Next, a specific configuration of the shielding device 14 described above will be described.

  FIG. 14 is a plan view showing a specific configuration of the shielding device 14 shown in FIG.

  Between the both sides in the longitudinal direction of the small tray 3B and the inner edge of the lift opening 13, rectangular shielding plates 44A and 44B supported on the floor side in the vicinity of the lift opening 13 are arranged. The shielding device 14A provided with the shielding plate 44A and the shielding device 14B provided with the shielding plate 44B have the same basic structure except for the orientation. Therefore, only the shielding device 14A provided with the shielding plate 44A will be described. . The shielding device 14 </ b> A has one driving device 46 and two state switching devices 47 that receive the driving force from the common driving device 46 and move the shielding plate 44 </ b> A between the non-shielding state and the shielding state.

  On the other hand, longer rectangular shielding plates 44C and 44D are disposed between both sides of the small tray 3B in the width direction and the inner edge of the lift opening 13, respectively. Since the shielding device 14C having the shielding plate 44C and the shielding device 14D having the shielding plate 44D have the same basic structure except for the orientation, only the shielding device 14C having the shielding plate 44C will be described. . The shielding device 14C is located at the center and both ends in the longitudinal direction and receives the driving force from the common driving device 46 to switch the shielding plate 44C between the non-shielding state and the shielding state. Three state switching devices 47 are provided.

  The shielding device 14 </ b> A has two state switching devices 47, whereas the shielding device 14 </ b> C has three state switching devices 47. However, both have basically the same configuration. Therefore, the operation will be described on behalf of the driving device 46 and one state switching device 47 in the shielding device 14C.

  15 and 16 are a plan view and a side view showing the non-shielding state of the shielding device 14C.

  When the shielding plate 44A of the shielding device 14C is rotated by the rotating shaft 49 supported by the floor 48 in the vicinity of the lift opening 13, the non-shielding state and the shielding state can be taken. On the lower side of the floor 48, a driving device 46 and one state switching device 47 are arranged. The drive device 46 is supported by a base 50 fixed to the floor 48, and one end of a link device 52 is connected to the rotary drive shaft 51. The other end of the link device 52 is connected to one end of an L-shaped lever 54 having a rotating shaft 53, and a state switching device 47 is connected to the other end of the L-shaped lever 54.

  In the non-shielding state shown in FIGS. 15 and 16, the shielding plate 44 </ b> A of the shielding device 14 </ b> C is housed in the vertical direction around the rotation shaft 49. The L-shaped lever 54 is rotated counterclockwise about the rotation shaft 53, and the state switching device 47 connected to the L-shaped lever 54 is positioned below the floor 48.

  Now, when a shielding command is given to the drive device 46, the rotation drive shaft 51 is rotated clockwise, the rotation shaft 53 of the L-shaped lever 54 is rotated clockwise via the link device 52, and the state switching device 47 is turned on. The operation starts.

  17 and 18 are a plan view and a side view showing the initial state of the shielding operation of the shielding device 14C.

  When the rotating shaft 53 of the L-shaped lever 54 is rotated clockwise, the state switching device 47 is moved clockwise around the rotating shaft 53. Since the L-shaped lever 54 has a certain length, the state switching device 47 is moved from the lower side of the floor 48 to the shielding plate 44A side, and the smooth curved surface at the top of the state switching device 47 is the shielding plate. 44A comes into contact with the rotating shaft 49 and starts to drive the shielding plate 44A.

  19 and 20 are a plan view and a side view showing a shielding state of the shielding device 14C.

  Eventually, the state switching device 47 causes the shielding plate 44A to be in a substantially horizontal shielding state about the rotation shaft 49, and as described above, exists between the outer periphery of the small tray 3B and the inner edge of the lift opening 13. Close the gap.

  As described above, all the trays 3A and 3B are configured to be movable by the tray-side guide rails provided on the back side thereof and the floor-side tray driving device 16 provided on the floor side of each storage space. There is no need to modify 2 to a special configuration. Further, since the shielding devices 14A to 14D are provided on the floor side in the vicinity of the lift opening 13, there is no need to add a complicated and large transit floor or the like to the lift device 2 side as in the prior art. Thus, the configuration of the lift device 2 is not complicated, and when the small tray 3B is mounted on the lift device 2 while using the same configuration as the conventional one, the outer periphery of the small tray 3B and the inner edge of the lift opening 13 are used. The large tray 3A and the small tray 3B can be mixed by closing the gap formed between the sections with a simple configuration.

  Further, since the large tray 3A and the small tray 3B are mixed only in the uppermost layer portion 8, there is no need to change the positions of the other intermediate layer portion 9, the lowermost layer portion 10 and the pillars 4A to 4N. For this reason, the conventional mechanical parking apparatus can be slightly modified to mix the large tray 3A and the small tray 3B.

  FIG. 21 is a side view showing a schematic configuration of a mechanical parking apparatus showing another embodiment of the present invention.

  The same components as those in the previous embodiment are denoted by the same reference numerals, detailed description thereof is omitted, and only different portions will be described. In each of the above-described embodiments, the case where a multi-layered floor is configured has been described. However, except for the plurality of pillars 4A to 4N in FIG. The large-sized tray 3A and the small-sized tray 3B are mixed on the floor 7 of only one layer. The configuration of the lift device 2 and the configuration of the shielding device 14 that closes the gap formed between the inner edge of the lift opening 13 and the outer periphery of the small tray 3B when the small tray 3B is mounted on the lift device 2 are the same as those described above. Similar to the example.

  Such a configuration could not be implemented in the conventional configuration, but by employing the present invention, the large tray 3A and the small tray 3B can be mixed even in a single floor configuration.

  In carrying out the present invention, the lift device 2 is constructed on the central wall side as shown in FIGS. 2 and 3, but it can be constructed not limited to this position. For example, it can be configured at the corner storage space position shown in FIGS. 2 and 3 or at the central storage space position.

  Moreover, in the Example mentioned above, although the large tray 3A and the small tray 3B were mixed in the uppermost layer part 8 of the mechanical parking apparatus, only the specific area of the whole uppermost layer part 8 or the uppermost layer part 8 was described. Can also be used as a mixed section. Furthermore, when carrying out the present invention, the large tray 3A and the small tray 3B can be mixed in the other intermediate layer portion 9 and the lowermost layer portion 10 as well. In this case, in the conventional configuration, each of the columns 4A to 4N located in the intermediate layer portion 9 and the lowermost layer portion 10 becomes an obstacle to the movement of the large tray 3A. Therefore, in such a mechanical parking device, the interval between the pillars 4A to 4N located in the intermediate layer portion 9 and the lowermost layer portion 10 is larger than the large tray 3A so that it can move both in the longitudinal direction and in the width direction. Change to

  As described above, in the mechanical parking apparatus according to the present invention, the tray on which the parked vehicle is to be moved has the large tray 3A for the large parked vehicle and the small tray 3B that is smaller than the large tray 3A. Then, the tray side guide rails provided on the back side of the large tray 3A and the small tray 3B, and the large tray 3A or the small tray 3B configured on the floor side of each storage space on the storage unit floor are moved to any storage space. When the floor-side tray driving device 16 and the small tray 3B are mounted on the lift device 2, the shielding devices 14A to 14D that block the gap formed between the inner edge of the lift opening 13 and the outer periphery of the small tray 3B are provided. And the shielding devices 14A to 14D are configured on the floor side in the vicinity of the lift opening 13.

  According to such a configuration, the configuration on the lift device 2 side is not complicated, and the outer periphery of the small tray 3B when the small tray 3B is mounted on the lift device 2 while using the same configuration as the conventional one. The large tray 3 </ b> A and the small tray 3 </ b> B can be mixed by closing a gap formed between the upper portion and the inner edge of the lift opening 13 with a simple configuration.

  Further, in addition to the above-described configuration, the present invention is characterized in that the storage unit has a configuration having only one floor and a configuration in which the large tray 3A and the small tray 3B are mixed on the single layer floor. .

  According to such a configuration, the large tray 3A and the small tray 3B can be mixed in a single floor configuration without forming a multilayer floor.

  In addition to the above-described configuration, the storage unit floor includes a plurality of pillars 4A to 4N and multilayer floors 5 to 7 configured using the pillars 4A to 4N. It is the structure which mixed the large tray 3A and the small tray 3B in the uppermost layer part floor 5 among ~ 7

  According to such a configuration, the uppermost floor 5 can be simplified to a configuration in which there are no columns 4A to 4N that prevent the movement of the large tray 3A and the small tray 3B, or no columns 4A to 4N, The large tray 3A larger than the small tray 3B can be used without restricting the movement of the large tray 3A by these columns 4A to 4N.
