A control means (not shown) performs a storage operation of the parked vehicle based on a program stored in advance, and guides to the storage floor shown in FIG. 2 by the lift mechanism in the storage operation, and then stores it in the parking space on the storage floor. I have to. In the delivery operation of the parked vehicle, for example, the tray 3n is moved by a tray feeding device, which will be described in detail later, while the empty section 4 is used, and this movement is sequentially repeated until it is moved to a predetermined position. The mounted tray 3n is guided to the loading / unloading floor by a lift mechanism.

  The tray feeding device configured for each storage section is mainly composed of the back side configuration of the trays 3a to 3n disposed for each storage section and the drive mechanism section disposed on the floor for each storage section. The back side configuration of the trays 3a to 3n will be described. Since each tray 3a-3n is the same structure, tray 3n is demonstrated here. The tray 3n has a rectangular plate shape on which the parked vehicle can be stably placed on the upper surface side thereof, and is enclosed by the vertical traveling rails 1g and 1n and the lateral traveling rails 2b and 2c in FIG. It is a little bigger than that. The back side of the tray 3n is shown in FIG.

  At the four corners on the back side, lateral wheels 21a to 21d that support the tray 3n to travel along the lateral traveling rails 2b and 2c, and the tray 3n to travel along the longitudinal traveling rails 1g and 1n. The supported longitudinal wheels 22a-22d are attached. Further, on a straight line 28 extending in the longitudinal direction at the center, fixed guide rails 23a, 23b, and 23c that are discretely arranged and fixed, and movable guide rails that are arranged between opposing portions of these fixed guide rails 23a to 23c. 24a and 24b are provided, and the movable guide rails 24a and 24b are rotatably supported around the central axes 25a and 25b. Further, when the movable guide rails 24a, 24b are rotated 90 degrees in the lateral direction, the fixed guide rails 26a, 26b, the fixed guide rail 27a, 27b is fixed.

  In other words, two sets of substantially cross-shaped fixed guide rails that are notched at the intersection are fixed to the back surface of the tray 3n, and the movable portions are rotatably supported around the central axes 25a and 25b at the intersections. Guide rails 24a and 24b are provided. The number of cross-shaped fixed guide rails can be increased or decreased according to the size of the tray 3n and the weight of the parked vehicle to be mounted.

  Therefore, in a state where the movable guide rails 24a and 24b are rotated in the vertical direction, the fixed guide rails 23a to 23c and the movable guide rails 24a and 24b are positioned on the straight line 28 in the vertical direction, and the movable guide rails 24a and 24b. In the state in which the fixed guide rails 26a, 26b and the movable guide rail 24a are positioned on the straight line 29, the fixed guide rails 27a, 27b and the movable guide rail 24b are respectively on the horizontal straight line 30. Will be located.

  Next, the other main component of the tray feeder, that is, the drive mechanism will be described with reference to FIG. The drive mechanism section 42 is configured on the base 5 fixed to the floor surface for each storage section, and is rotatably provided by the rotary shaft 6 provided at substantially the same position as the rotary shaft 25a shown in FIG. The second drive device 15 rotatably provided by the drive device 7 and the rotary shaft 14 provided at substantially the same position as the rotary shaft 25b shown in FIG. 3, and these first drive device 7 and second drive device 15 And a switching drive device 12 that switches and rotates the rotary shafts 6 and 14.

  The switching drive device 12 has a lever 11 that can rotate around a rotation shaft 11a. A link 18 connected to one end of the lever 11 is connected to an arm 10 fixed to the rotation shaft 6 of the first drive device 7. Has been. A link 19 connected to the other end of the lever 11 is connected to an arm 20 fixed to the rotary shaft 14 of the second drive device 15.

  The first driving device 7 sandwiches the motor 8, the feed roller 9 that is a friction roller that is rotationally driven by the motor 8, and the movable guide rail 24 a that is located on both sides of the rotating shaft 6. Two pairs of feed guide rollers 31 and 32 arranged opposite to each other are provided. The second drive unit 15 has the same configuration, and sandwiches the motor 16, the feed roller 17 that is a friction roller that is rotationally driven by the motor 16, and the movable guide rail 24 b located on both sides of the rotary shaft 14. Two sets of feed guide rollers 31 and 32 arranged to face each other are provided.

  In the state shown in the drawing, the feed roller 9 and the feed roller 17 are rotatable so as to move along the vertical straight line 28 in which the fixed guide rails 23a, 23b, 23c shown in FIG. When the lever 11 is rotated counterclockwise by a predetermined angle by the twelve motors 13, the first driving device 7 connected via the link 18 rotates counterclockwise by 90 degrees about the rotation shaft 6, The second driving device 15 connected through the link 19 rotates by 90 degrees counterclockwise about the rotating shaft 14. Due to the above-described rotation of the first drive device 7 and the second drive device 15, the movable guide rails 24a and 24b sandwiched between the feed guide rollers 31 and 32 are also rotated 90 degrees. In this state, the motor 8 feeds the feed roller 9 Is rotated so that the fixed guide rails 26a and 26b shown in FIG. 3 move along the straight line 29 in the horizontal direction, and when the feed roller 17 is rotated by the motor 16, FIG. The fixed guide rails 27a and 27b shown in FIG. 5 are rotated so as to move along the straight line 30 in the horizontal direction.

  Next, specific configurations of the first drive device 7 and the second drive device 15 in the drive mechanism unit 42 will be described. Since the 1st drive device 7 and the 2nd drive device 15 are the same structures, the 1st drive device 7 is demonstrated here and detailed description about the 2nd drive device 15 is abbreviate | omitted. As shown in FIG. 6 which is an enlarged view, the first driving device 7 is provided with two sets of feed guide rollers 31 and 32 facing each other at a predetermined distance at a position sandwiching the rotation shaft 6. The movable guide rail 24a shown in FIG. 3 is located between the two sets of feed guide rollers 31 and 32. When the rotary shaft 6 of the first drive device 7 is switched and rotated, the movable guide rail 24a is moved in the same direction. Then, as the tray 3n moves, the feed guide rollers 31 and 32 roll on the side surfaces of the movable guide rail 24a and the like. A feed roller 9 is attached to the rotation shaft 33 of the motor 8, and the rotation shaft 33 and the feed roller 9 are rotatably supported by a swing member 34, which will be described in detail later.

  When the feed roller 9 is appropriately pressed against the lower surface of the movable guide rail 24a and the rotational force of the feed roller 9 applied from the motor 8 is transmitted to the movable guide rail 24a, the tray 3n moves, for example, along the straight line 28. become. Next, a configuration for pressing the above-described feed roller 9 against the movable guide rail 24a and the like will be described with reference to FIGS.

A rotating shaft 6 erected via a bearing 36 is rotatably supported by a support fixing portion 35 fixed to the base 5 shown in FIG. A receiving fixing plate 37 is fixed to the upper end portion of the rotating shaft 6, and the two sets of feed guide rollers 31 and 32 described above are supported on the receiving fixing plate 37 and one end of the spring insertion shaft 38. Is fixed. Further, the swinging member 34 described with reference to FIG. 6 is formed in a U shape so as to wrap around the feed roller 9, and further between the opposing portions 43 a and 43 b forming the U shape, the rotating shaft 6 and the spring 40. Is stored. A connecting shaft 41 penetrating the upright rotating shaft is inserted into the opposed portions 43 a and 43 b of the swinging member 34 on which the rotating shaft 6 is disposed. The connecting shaft 41 causes the swinging member 34 to be connected to the rotating shaft 6. On the other hand, both ends are supported so as to be swingable.

Thus one is on the side feed roller 9 and the motor 8 of the swinging member 3 4 which is swingably supported is supported, the spring 40 is arranged on the other side of the swinging member 3 4. The spring 40 provides a spring force for pressing the feed roller 9 against the movable guide rail 24a and the like. The spring receiver movable member 39 formed integrally with the swing member 34 and the above-described receiving fixing plate 37 are provided. The spring 40 is opposed to the spring receiving movable member 39 and the receiving fixing plate 37 by fixing the other end of the spring insertion shaft 38 inserted in the spring 40 on the spring receiving movable member 39 side. Hold between the clubs.

  With this configuration, the spring 40 acts on the spring receiving movable member 39, and the swinging member 34 is urged counterclockwise in FIG. 4 around the connecting shaft 41. In the steady state shown in FIG. The uppermost point is held so as to be located slightly above the upper surface of the receiving fixing plate 37.

  Therefore, when the movable guide rail 24a is positioned between the two pairs of feed guide rollers 31, 32, the lower surface of the movable guide rail 24a, that is, the surface located on the tray feed device 42 side is the receiving fixing plate 37 shown in FIG. It is positioned slightly above the upper surface of the roller and press-contacted so as to push the feed roller 9 downward. In a state where the movable guide rail 24a is positioned on the feed roller 9, a clockwise rotational force in FIG. 4 acts on the swinging member 34 supporting the feed roller 9 around the connecting shaft 41, and the spring receiving movable member. 39 is moved upward to compress the spring 40, but an appropriate reaction force corresponding to the compression of the spring 40 acts on the swing member 34. Accordingly, the swinging member 34 tries to rotate counterclockwise around the connecting shaft 41, and the feed roller 9 is pressed to the lower surface of the movable guide rail 24a and the like.

  However, at this time, the tray 3n has the lateral wheels 21a to 21d and the longitudinal wheels 22a to 22d shown in FIG. 3 on the longitudinal traveling rails 1g and 1n and the lateral traveling rails 2b and 2c shown in FIG. Therefore, an extremely large load is not applied to the feed roller 9 from the movable guide rail 24a.

  According to the first driving device 7 and the second driving device 15, when the feed rollers 9 and 17 are pressed against the movable guide rails 24 a and 24 b by the spring 40, the connecting shaft 41 is connected to the rotary shafts 6 and 14. Since the swinging rotation of the supported swinging member 34 is used, it is possible to carry out smoothly as compared with the method of sliding the rotating shafts 6 and 14 in the axial direction as in the conventional configuration, and galling occurs. Therefore, the feed rollers 9 and 17 can be always pressed against the movable guide rails 24a and 24b with a suitable force. Further, since the oscillating member 34 is oscillated with the rotary shafts 6 and 14 as fulcrums, the feed rollers 9 and 17 are moved along the movable guide rails 24a depending on the distance from the rotary shafts 6 and 14 to the rotary shaft 33 of the feed roller 9. , 24b and the like can be easily selected, and the heights of the first drive device 7 and the second drive device 15 can be suppressed. For this reason, in order to press the feed rollers 9 and 17 against the movable guide rails 24a and 24b, etc., even if the stroke of the oscillating member 34 is secured, the stroke is secured in the axial direction of the rotary shafts 6 and 14 as before. The height direction can be suppressed as compared with the case of doing so.

  When the motors 8 and 16 are driven by control means (not shown) in a state where the feed rollers 9 and 17 are in pressure contact with the movable guide rails 24a and 24b, the rotational force of the feed rollers 9 and 17 is transmitted to the movable guide rails 24a and 24b. Thereafter, it is transmitted to other fixed guide rails in the vicinity, and the tray can be driven according to the rotation direction of the feed rollers 9 and 17.

  Next, a configuration in which the shaft coupling is omitted and the driving force of the motor 8 is transmitted to the feed roller 9 will be described with reference to FIGS. 7 and 8.

  A rotary shaft 33 supported by bearings 50a and 50b fixed to the opposed portions 43a and 43b of the swing member 34 is provided. On one side of the rotary shaft 33, the feed roller 9 is connected to the first key 52 and the first key. The shaft 8a of the motor 8 is connected to the second key 54 and the second key groove 55 facing the second key 54 on the other side of the rotating shaft 33. It is made to fit through.

  With this configuration, the driving force of the motor 8 is such that the side surface of the second key 54 provided on the shaft 8 a of the motor 8 is joined to the side surface of the second key groove 55 formed on the other side of the rotating shaft 33. Then, the driving force of the shaft 51 is applied to the feed roller 9 by joining the side surface of the first key 52 provided on one side of the shaft 51 to the side surface of the first key groove 53 formed in the feed roller 9. Communicated.

  According to the first driving device 7 and the second driving device 15 as described above, it is possible to transmit the driving force of the motor 8 to the feed roller 9 by omitting a conventional shaft coupling, and accordingly, the width of the driving device. The size can be reduced.

  Next, the case where the tray 3n shown in FIG. 2 is moved to the left empty section 4 will be described. The moving direction according to the rotation direction of the feed rollers 9 and 17 in the drive mechanism unit 42 shown in FIG. 1 is the front-rear direction, which is different from the desired direction. Therefore, first, the control means (not shown) operates the motor 13 of the switching drive device 12 to drive the lever 11 counterclockwise, and the rotation shaft 6 of the first drive device 7 is counterclockwise via the link 18. The rotary shaft 14 of the second drive device 15 is rotated 90 degrees counterclockwise through the link 19. Then, the feed roller 9 of the first drive device 7 and the feed roller 17 of the second drive device 15 are turned sideways.

  At this time, the movable guide rail 24a shown in FIG. 3 is sandwiched between the feed guide rollers 31 and 32 of the first drive device 7, and the feed guide rollers 31 and 32 of the second drive device 15 are shown in FIG. Since the movable guide rail 24b is sandwiched, the movable guide rail 24a and the movable guide rail 24b also rotate 90 degrees. Therefore, the movable guide rail 24a connects the fixed guide rail 26a and the fixed guide rail 26b, and the movable guide rail 24b connects the fixed guide rail 27a and the fixed guide rail 27b. As described above, the feed roller 9 of the first driving device 7 is pressed against the lower surface of the movable guide rail 24a of the tray 3n by the spring 40, and the lower surface of the movable guide rail 24b is fed by the second driving device 15. The roller 17 is in pressure contact with the spring 40.

  Thereafter, when the motors 8 and 16 of the first drive device 7 and the second drive device 15 are driven by control means (not shown), the second key 54, the second key groove 54, the rotary shaft 33, the first key 52, and the first key. The feed roller 17 is transmitted to the feed roller 39 through the groove 53, and the rotational force of the feed roller 9 is transmitted to the movable guide rail 24a, the fixed guide rails 26a and 26b, and the like. Is transmitted to the movable guide rail 24b, the fixed guide rails 27a and 27b, etc., so that the tray 3n moves to the empty section 4 along the straight lines 29 and 30 according to the rotation direction of the feed rollers 9 and 17. Can be made. As shown in FIG. 3, the movement of the tray 3n is favorably performed because the lateral wheels 21a to 21d provided in the lower part thereof rotate along the lateral traveling rails 2b and 2c shown in FIG.

  As can be understood from this explanation, when moving a tray on which a parked vehicle for taking out a garage is moved, the movement of each switching drive device 12 described above by the control means storing the operation pattern assembled according to the position of the tray. It is possible to move to the lift mechanism by freely moving back and forth and right and left while controlling the direction.

  In particular, such a tray feeding device supports a swinging member 34 on a rotating shaft 6 rotatably supported as shown in FIG. Since the feed roller 9 is attached to the end side and the spring 40 is attached to the other end side, even if the movable guide rail 24a provided on the lower surface side of the tray is placed on the feed roller 9, the conventional galling occurs. It does not occur, and a stable force of the spring 40 can always be applied as a pressure contact force from the feed roller 9 to the movable guide rail 24a. Further, since the oscillating member 34 is oscillated with the rotary shafts 6 and 14 as fulcrums, the feed rollers 9 and 17 are moved along the movable guide rails 24a depending on the distance from the rotary shafts 6 and 14 to the rotary shaft 33 of the feed roller 9. , 24b and the like can be easily selected, so that the first drive device 7 and the second drive device 15 can be configured without increasing the height in the conventional manner.

  Further, as the tray feeding device, a receiving fixing plate 37 is attached to an end portion of the rotating shafts 6 and 14 provided in the first driving device 7 and the second driving device 15 on the tray 3n side, and this receiving fixing plate is attached. 37 is provided with at least a pair of feed guide rollers 31 and 32 that sandwich the movable guide rails 25a and 25b and transmit the rotational force to the movable guide rails 24a and 24b, and holds one end of the spring 40, and the other end of the spring 40 Is supported by the oscillating member 34, and the feed rollers 9, 17 and the spring 40 are arranged in a balanced manner on both sides of the coupling shaft 41 of the oscillating member 34 coupled to the rotary shafts 6, 14 by the coupling shaft 41. Can be simplified. Further, it becomes easy to adjust the lever ratio determined by the distance from the connecting shaft 41, and the force for pressing the feed rollers 9, 17 to the movable guide rails 25a, 25b can be adjusted appropriately.

  Further, a rotating shaft 33 supported by bearings 50a and 50b fixed to the opposed portions 43a and 43b of the swing member 34 is provided. On one side of the rotating shaft 33, the feed roller 9 is connected to the first key 52 and the first key 52. The shaft 8a of the motor 8 is fitted on the other side of the shaft 51 with the second key 54 and the second key groove 55 facing the second key 54 while being fitted through the first key groove 53 facing the one key 52. The width dimension of the drive device can be reduced by fitting through the connector, thereby saving the space of the device and improving the mediocrity.

  In the above-described embodiment, the tray feeding device of the plane circulation parking facility that manages the parked vehicles mounted on the trays 3a to 3n has been described. However, other articles are mounted and managed on the trays 3a to 3n. The present invention can be applied to a tray feeder of a planar circulation type management facility. If the article mounted and managed on the trays 3a to 3n is smaller and lighter than the parked vehicle, it is configured by only one of the first driving device 7 and the second driving device 15 and provided on the lower surface of the tray 3n. The movable guide rails 25a and 25b can also be only one of the corresponding sides.

  Moreover, the connection structure of the 1st drive device 7, the switching drive device 12, and the 2nd drive device 15 is applicable not only to the thing of illustration.

  In addition, an example has been given in which a plurality of lateral traveling rails are arranged so as to be orthogonal to a plurality of longitudinal traveling rails to form a plurality of storage compartments in a matrix shape. The tray may be placed directly on the roller of the driving unit, and in this case, the traveling rail is not necessary. Further, the present invention can be applied to a case where the storage compartment is not a matrix.

  Furthermore, although the example which provided the movable guide rail and was provided with the switching means was shown, if it is a movement of only a horizontal direction or a vertical direction, a movable guide rail and this switching means are unnecessary, and this application is applicable also in this case.
