Held at the same level. In the present embodiment, both the inner movable deck 35 and the outer movable deck 81 are attached to the transporter 13 so as to be movable up and down. Here, “movable up and down” means that a drive source for raising and lowering the movable deck is not provided in the transporter, and the movable deck can freely move up and down by an external force. Since the transporter 13 is basically configured symmetrically, the following description will focus on one side portion of the transporter 13 (one inner movable deck 35 and one outer movable deck 81) unless otherwise specified. To do.

  As shown in FIG. 8, each of the inner movable deck 35 and the outer movable deck 81 includes a rectangular frame-like frame in plan view and a plate fixed to the upper surface of the frame.

  As shown in FIG. 3, a crank arm 43 and an arm turning mechanism 40 for turning the crank arm 43 are disposed below the inner movable deck 35. The crank arm 43 and the arm turning mechanism 40 constitute the pallet transfer mechanism 25 described above. That is, the pallet transfer mechanism 25 in the present embodiment is a twin crank arm system having two crank arms 43 on the left and right of the swivel base 27. The pallet transfer mechanism 25 has a simple structure by making the rotation center of the crank arm 43 coincide with the center in the width direction of the transporter 13.

  A vertical support 42 projects upward from the tip of the crank arm 43, and an engagement roller 41 is provided at the upper end of the vertical support 42 (see FIG. 5 for details). On the other hand, on the long side of the pallet 20 that faces the hoistway 10 when stored in the parking rack 11, it is for transverse transfer that can be opened downward and engaged with the engagement roller 41 in the center in the Y direction. A groove member 21 is provided. The base 44 of the crank arm 43 is supported so as to be horizontally rotatable.

These guide bars 83 are slidably inserted into a guide cylinder 82 provided in the frame 30 of the transporter 13. In other words, the outer movable deck 81 is supported by the guide cylinder 82 so as to be movable up and down. The outer movable deck 81 is usually positioned below the crank arm 43 due to its own weight. For this reason, except when the transporter 13 is positioned at the loading / unloading position (that is, when the inner movable deck 35 and the outer movable deck 81 are supported by the support member 90), A step is formed between the two.

  The structure for supporting the inner movable deck 35 and the outer movable deck 81 so as to be movable up and down is not limited to the above-described structure, and a link mechanism, a linear guide, a roller and a guide plate, a shoe and a guide plate, and the like may be employed. is there. These structures can be arbitrarily combined, and an appropriate structure can be adopted for each of the inner movable deck 35 and the outer movable deck 81.

  As shown in FIG. 3, a pallet that supports a pallet 20 that traverses between the transporter 13 and the parking shelf 11 on both the left and right sides of the outer movable deck 81 of the transporter 13 and the left and right ends of the parking shelf 11 described above. A mounting traverse support mechanism 55 is provided.

The pallet 20 is transferred between the transporter 13 and the parking rack 11 while being guided by these rollers 56 and 57.

  Further, in the present embodiment, as shown in FIG. 2, the inner side movable deck 35 and the outer side movable deck 81, which are attached to the transporter 13 so as to freely move up and down, are connected to the front deck unit 3A and the rear deck unit 3B. As a configuration for forming the floor surface, the support mechanism 9 is disposed below the fixed deck 32 of the front deck unit 3A and the fixed deck 33 of the rear deck unit 3B. Since these support mechanisms 9 have the same configuration, the configuration of the right rear support mechanism 9 will be described in detail below with reference to FIGS. 7A and 7B and FIG.

  The support mechanism 9 includes a support member 90 that moves between a support position that moves into the hoistway 10 to support the inner movable deck 35 and the outer movable deck 81 and a retracted position that retreats below the fixed deck 33. ing. When the inner movable deck 35 and the outer movable deck 81 are supported by the support member 90, the upper surfaces of the inner movable deck 35 and the outer movable deck 81 are located on the same plane as the upper surfaces of the fixed deck 32 and the fixed deck 33, and are movable inside. The deck 35 and the outer movable deck 81 are held at the same level as the front deck unit 3A and the rear deck unit 3B.

  In the present embodiment, the support member 90 includes a rotary shaft 92 extending in the Y direction, and is configured to swing around the rotary shaft 92. However, the support member 90 may be configured to be movable back and forth in the horizontal direction between the support position and the retracted position, for example.

  Both ends of the rotary shaft 92 are rotatably supported by the bearing 99. The bearing 99 is attached to a pair of L-shaped pillars 98 suspended from a beam (not shown) that supports the rear fixed deck 33.

  The support mechanism 9 includes a linear actuator 47 as a drive source for driving the support member 90. A bracket 48 that passes through the rotary shaft 92 and is pointed downward from the rotary shaft 92 is attached to the rotary shaft 92. One end of the linear actuator 47 is pin-coupled to a sharp portion of the bracket 48. On the other hand, the other end of the linear actuator 47 is pin-coupled to a bracket 46 attached to a column 45 having a U-shaped cross section. For example, the column 45 is suspended from the same beam as the beam from which the column 98 is suspended. When the linear actuator 47 is extended, the support member 90 swings to the retracted position indicated by a two-dot chain line in FIG. 8, and when the linear actuator 47 is shortened, the support member 90 is moved to the support position indicated by the solid line in FIG. Swing.

  However, the means for swinging the support member 90 is not limited to the linear actuator 47, and may be a sprocket fixed to the rotary shaft 92 and a mechanism around which a chain is wound, a rack and pinion mechanism, or the like.

  In addition to the rotating shaft 92, the supporting member 90 includes a connecting member 91 that extends above the rotating shaft 92 and extends in parallel with the rotating shaft 92, and a plurality (three in the illustrated example) that couple the connecting member 91 and the rotating shaft 92. Arm 93. The connecting member 91 has a length approximately equal to the total width of the inner movable deck 35 and the outer movable deck 81. In the present embodiment, the connecting member 91 is a square pipe whose upper surface and lower surface are horizontal at the support position. A rubber plate 95 for receiving portions near the corners of the movable decks 35 and 81 is attached to the upper surface of the connecting member 91 via a seat. The central rubber plate 95 is used in common for the inner movable deck 35 and the outer movable deck 81. The arm 93 is disposed at a position corresponding to the rubber plate 95.

  Each outer arm 93 located near the bearing 99 is integrally provided with a stay 94 that protrudes from the rotating shaft 92 to the opposite side of the rubber plate 95. A rubber plate 96 that is parallel to the vertical direction when the support member 90 swings to the support position is attached to the tip of the stay 94 via a seat. On the other hand, the pillar 98 is provided with a stopper 51 having an L-shaped cross section so as to be in surface contact with the rubber plate 96. That is, the stopper 51 contacts the stay 94 through the rubber plate 96 when the support member 90 swings to the support position.

  A connecting member 52 having an L-shaped cross section is spanned between the pair of columns 98 described above (drawing is omitted in FIG. 7A). The connecting member 52 is provided with a stopper 53 that contacts the arm 93 when the support member 90 swings to the retracted position at a position corresponding to the arm 93 on the inner movable deck 35 side. The stopper 53 is of a bolt type with rubber attached to the head.

  Furthermore, in the present embodiment, a configuration is adopted in which small items can be collected even if they fall into the gap G between the movable decks 35 and 81 and the rear deck portion 3B. Specifically, the support member 90 includes a fall prevention member 97 that is disposed above the rotation shaft 92 and extends along an edge facing the opening 37 in the rear deck portion 3B. The fall prevention member 97 has a length approximately equal to the total width of the inner movable deck 35 and the outer movable deck 81 in the same manner as the connecting member 91 so as to bear the entire length of the gap G.

  More specifically, the fall prevention member 97 is perpendicular to the fall prevention wall 97a that closes the gap G from below when the support member 90 advances into the hoistway 10, and from the end of the fall prevention wall 97a opposite to the carrier 13. And a side wall 97b that rises in an L shape. The fall prevention wall 97 a is joined to the upper surface of the connecting member 91. For this reason, the fall prevention wall 97a is horizontal when the support member 90 is swung to the support position, and is inclined downward toward the direction away from the opening 37 when the support member 90 is swung to the retracted position. . The fall prevention wall 97a has a notch so as to avoid interference with the seat for the rubber plate 95.

  Although the material which comprises the supporting member 90 (The rotating shaft 92, the arm 93, the connection member 91, and the fall prevention member 97) is not specifically limited, It is desirable that the supporting member 90 consists of nonmagnetic materials. This is because if the small item dropped into the gap G is made of a magnetic material, the small item can be easily picked up using a magnet.

  Next, with reference to FIGS. 9-13, the operation | movement at the time of warehousing in the parking apparatus 1 of this embodiment is demonstrated.

  As shown in FIG. 9, the empty pallet 20 on the parking shelf 11 above or below the ground is lowered or raised toward the boarding floor 3 after the carrying device 13 is transferred onto the carrying device 13 by turning the crank arm 43 inward. To do. At this time, the support member 90 is located at the retracted position.

  Next, when the transporter 13 is positioned slightly above the loading / unloading position, the linear actuator 47 swings the support member 90 to the support position. Thereafter, when the transporter 13 is lowered, the outer movable deck 81 is first placed on the support member 90 as shown in FIG. Next, when the transporter 13 is further lowered, the step between the outer movable deck 81 and the inner movable deck 35 is gradually reduced, and the inner movable deck 35 is placed on the support member 90. Thus, the movable decks 35 and 81 form a floor surface that is continuous with the front deck portion 3A and the rear deck portion 3B.

  Thereafter, when the transporter 13 is further lowered, the pallet 20 is deposited on the inner movable deck 35 and the outer movable deck 81 to stop the lowering, and the engaging roller 41 of the crank arm 43 moves downward from the groove member 21 of the pallet 20. Start to leave.

  Next, as shown in FIG. 11, the swiveling device 26 with a lifting function provided in the transporter 13 raises the swivel base 27, so that the upper end of the engaging roller 41 is moved from the groove member 21 of the pallet 20. Raised until completely disengaged. In this state, as shown in FIG. 12, the swivel base 27 is turned 90 degrees, the pallet 20 is turned 90 degrees from the second state to the first state, and the extending direction is the loading / unloading port 6 (see FIG. 1). ). During this pallet turning, the crank arm 43 is turned slightly outward so that the engaging roller 41 is accommodated in the groove member 21 when the pallet 20 in the first state descends after turning (the groove member 21 is provided). The same applies to the crank arm 43 on the non-side).

  Next, as shown in FIG. 13, by the lowering operation of the turning device 26, the turntable 27 and the pallet 20 in the first state are lowered integrally, and the wheel running surface 86 of the pallet 20 is the floor surface of the entrance floor 3. When aligned, the pallet 20 is deposited in another member (not shown) provided in the space 39 of the front deck portion 3A and the rear deck portion 3B. Thereafter, the swivel base 27 is further lowered and returned to the original position.

  By performing the operation as described above, the wheel running surface 86 of the pallet 20, the inner movable deck 35, the outer elevator deck 81, the front deck unit 3 </ b> A and the rear deck unit 3 </ b> B are all in contact with the floor surface of the entry floor 3. The entire entrance floor 3 can be formed in a flat entry / exit space (excluding the two long sides of the pallet 20 and the central rising part) with no level difference.

  As described above, in the parking device 1 of the present embodiment, even if an accessory falls in the gap G between the movable decks 35 and 81 of the transporter 13 and the deck portion (3A or 3B), the accessory does not fall. Received at 97a. Accordingly, the dropped small item can be collected from the gap G. Further, since the fall prevention wall 97a is provided on the support member 90 configured to be able to advance and retreat to support the movable decks 35 and 81, a dedicated actuator for collecting the fallen object is unnecessary.

  Further, since the side wall 97b rises from the end of the fall prevention wall 97a opposite to the transporter 13, even if the fallen small object bounces on the side opposite to the transporter 13 on the fall prevention wall 97a, the side wall 97b causes the accessory Can be held on the fall prevention wall 97a. Moreover, the side wall 97b can prevent small items from sliding off the fall prevention wall 97a when the support member 90 swings to the retracted position and the fall prevention wall 97a is inclined.

(Modification)
The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

  For example, like the support member 90A of the first modification shown in FIG. 14, the fall prevention member 97 is integrally provided with a second side wall 97c that rises from the end of the fall prevention wall 97a on the side of the carrier 13. Also good. According to this configuration, even if a small item that has fallen bounces to the transporter 13 side on the fall prevention wall 97a, the small item can be held on the fall prevention wall 97a by the second side wall 97c.

  Further, the fall prevention wall 97a does not necessarily need to be configured as a separate member from the connecting member 91, and may be a part of the connecting member 91. For example, like the support member 90B of the second modification shown in FIG. 15, the first connecting member 91 is configured by a U-shaped groove member that opens upward with a width larger than the gap G, The plate 91a may be bridged at the corresponding position. In this case, the bottom of the first connecting member 91 becomes the fall prevention wall 97a, and both the vertical walls become the side wall 97b and the second side wall 97c. According to this structure, compared with the case where the fall prevention member 97 including the fall prevention wall 97a is joined to the connecting member 91, the number of members can be reduced.

  Alternatively, like the support member 90C of the third modified example shown in FIG. 16, when the support member 90 swings to the support position, the connection member 91 made of each pipe is connected so that the upper surface overlaps the gap G in the vertical direction. The position of the member 91 may be changed. In this case, the surface portion constituting the upper surface of the four surface portions orthogonal to each other of the connecting member 91 becomes the fall prevention wall 97a. In this case, the receiving member 97 </ b> A may be disposed on the side opposite to the transporter 13 with respect to the connecting member 91. The receiving member 97A is a groove member that opens upward at a position lower than the fall prevention wall 97a and has a length similar to that of the connecting member 91. That is, the receiving member 97A forms a groove adjacent to the fall prevention wall 97a. According to this configuration, when the support member 90C swings to the retracted position and the fall prevention wall 97a is inclined, even if the accessory slips off from the fall prevention wall 97a, the accessory can be received by the receiving member 97A. it can.

  In the embodiment, both the inner movable deck 35 and the outer movable deck 81 are attached to the main body portion 17 of the transporter 13 so as to be movable up and down. However, only one of the inner movable deck 35 and the outer movable deck 81 is attached to the main body portion 17. It may be attached so as to be movable up and down. In this case, the other of the inner movable deck 35 and the outer movable deck 81 may be attached to the main body portion 17 via an elevating mechanism that moves the movable deck up and down, or may be fixed to the main body portion 17. However, the inner movable deck 35 and the outer movable deck 81 can both move up and down independently, or one can move up and down, and the other can be moved up and down by a lifting mechanism. It is desirable. Alternatively, a movable deck in which the inner movable deck 35 and the outer movable deck 81 are integrated may be attached to the main body portion 17 of the transporter 13 so as to be movable up and down.

  Further, the support member 90 is not necessarily required to support the movable deck, and may support the main body portion 17 or the pallet 20 of the transporter 13 at the support position. When the support member 90 supports the main body portion 17 of the transporter 13, the fall prevention wall 97 a only needs to close the gap between the main body portion 17 and the deck portion (3 </ b> A or 3 </ b> B) from below, and the support member 90 holds the pallet 20. When supporting, the fall prevention wall 97a should just block the clearance gap between the pallet 20 and the deck part (3A or 3B) from the downward direction.

  Moreover, the turning device 26 is not necessarily provided in the main body portion 17 of the transporter 13. For example, in FIG. 2, a warehousing port and a warehousing port may be separately provided on both sides in the Y direction.
