BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is for transmitting the driving force of a conveyor device provided on, for example, a traveling carriage at a plurality of parking floors to a conveyor device provided in a parking room or an elevator of an automobile elevator. Conveyor power transmission device

[0002]

2. Description of the Related Art In a multi-story parking lot where automobiles are loaded and unloaded through a pallet or directly into and out of a parking space provided on a plurality of parking floors, for example, a traveling carriage is arranged in the central space of each parking floor. Parking shelves are provided on both sides of the central space along the traveling direction of the traveling carriage, and these parking shelves are divided into a plurality of parking rooms, and any one of these parking rooms is used as an elevator space for an elevator device for an automobile. There is one in which a conveyor device capable of delivering an automobile is provided in each of the parking room, the traveling carriage, and the lift of the elevator device.

In this multi-storey car park, if each of the conveyor devices is provided with a drive device, the cost becomes high, and in particular, the thickness of the conveyor device increases in the parking room and the height of the parking space increases. Occurs. Therefore, the applicant of the present invention has proposed a device for transmitting the driving force of the conveyor device provided on the traveling carriage to the conveyor device in the parking room in Japanese Patent Application No. 63-26.
Filed No. 3722.

As shown in FIG. 8, an intermediate gear 63 is fixed to an interlocking shaft 62 which is interlocked with a rotary drive motor 61, and the swinging arms 6 are provided on both sides of the intermediate gear 63.
4, a transmission gear 65 that meshes with the intermediate gear 63 and a stopper 66 having a conductor 66a are attached to an intermediate portion of the swing arm 64, and the swing arm 64 is attached to the interlocking shaft 62 by a jack 67. The transmission gear 65 is configured to oscillate forward around the center so that the transmission gear 65 meshes with the passive gear 69 on the parking room 68 side.
The engagement with and is detected by the position detecting limit switches 70A and 70B of the swing arm 64, the conductor 66a, and the stopper receiver 71 abutting against the conductor 66a.

[0005]

However, in this conventional example, when the jack 67 is operated for a certain period of time to cause the transmission gear 65 to project and move, and the limit switch 70B does not detect the swing arm 64 within a certain period of time, the tooth Is judged to be in a butted state, the transmission gear 65 is slightly rotated with the jack 67 slipped, and then the jack 6
When the limit switch 70B detects the swing arm 64, the jack 67 causes the transmission gear 65 to further project, and the stopper 66 causes the stopper receiver 71 to operate.
The contact with the contact is detected by the charged conductor 66a and the jack 67 is stopped. As described above, since the engagement of the gears is detected by using the detector such as the limit switch 70B and the conductor 66a, it takes time for the engagement operation and fine adjustment of these members is required, and further transmission is required. In many cases, the tooth tips of the gear 65 and the passive gear 69 come into contact with each other, and the withdrawal operation is repeated, so that it takes time to accurately engage with each other. Further, since the gear of the load side conveyor is fixed, the gear on the non-load side is rotated by the turning force of the transmission gear 65 that moves in the arc direction when the transmission gear and the passive gear are meshed or separated. The device was activated and moved up to 25 mm. This complicates the position control of the conveyor device.

The present invention solves the above problems and allows the gears to mesh with each other in a short time, and does not move the unloaded side conveyor device when the gears are meshed or disengaged. An object is to provide a transmission device.

[0007]

In order to solve the above problems, a conveyor power transmission device in a multi-storey parking lot according to the present invention has a traveling carriage arranged in a central space of each parking floor and both sides of the central space. Provide a parking rack in which a plurality of parking rooms are divided along the traveling direction of the traveling carriage, and use any one of these parking rooms as an elevating space for an automobile elevator device, and the parking room, traveling carriage, and elevator device In a multi-storey parking lot equipped with a conveyor device that can deliver cars to the lift platform, an interlocking shaft that is linked to the conveyor system for the traveling car along the traveling direction of the traveling car is provided in the parking room facing area of the traveling car. The drive gear is fixed to the interlocking shaft and the swing arm is rotatably supported, and the swing arm is engaged with the drive gear and at least the parking chamber is connected. A transmission gear that can be meshed with a passive gear that is interlocked with the gear device is provided, and an idle roller having the same diameter as the pitch circle is provided on the transmission gear and the passive gear, respectively, on the same axis as the transmission gear and the passive gear. A clutch capable of rotating the moving arm to move the transmission gear to the parking room side and engaging the transmission gear with the passive gear, and the drive gear being idle between the traveling carriage conveyor device and the drive gear. The moving device is provided with a mesh detector for detecting the mesh between the drive gear and the passive gear.

[0008]

In the above structure, when the traveling carriage is stopped facing the parking room and the vehicle is loaded or unloaded, the clutch is operated to make the transmission gear idle, and the moving device is driven to swing the arm. Is rotated to move the transmission gear to the passive gear side of the parking room so that the transmission gear meshes with the passive gear. At this time, since the transmission gear is in an idling state in which no load is applied, the transmission gear and the passive gear can be meshed with each other with a very high probability of rotating by light contact. Then, the idle roller on the transmission gear side comes into contact with the idle roller on the passive gear side to form an accurate meshing state, which is detected and confirmed by the meshing detector of the moving device, and the coupling of both conveyor devices is completed. Also, when disengaged, the clutch is operated and the swinging arm is rotated by the moving device to disengage the transmission gear from the passive gear.

Therefore, since the gears are properly meshed by the idle roller and this is detected by the meshing detector of the moving device, stepwise projection and confirmation are not necessary, and the time required for gear meshing is eliminated. Can be shortened. Also, since the transmission gear is made to idle by the clutch, the transmission gear and the passive gear can be easily meshed, and the gear on the unloaded side can be rotated by the movement in the rotation direction when meshing and disengaging the gear. There is no need to operate the conveyor system on the unloaded side.

A passive gear 53 capable of meshing with the transmission gear 46 is fixed to the passive shaft 52, and a pair of receiving idle rollers 54 with which the idle roller 47 can abut are provided on the passive shaft 52. It is attached to the passive shaft 52 on both sides of 53.

The slat conveyors 12A and 12B provided on the lift 9 of the elevator device 8 may be equipped with a drive device, although they are not shown in detail in the drawings. It may be driven by the power transmission device 41 of the carriage 5.

Next, the operation of the power transmission device 41 will be described. (1) The automobile is transferred from the elevator 9 of the elevator device 8 onto the slat conveyors 10A and 10B of the traveling carriage 5, and the traveling carriage 5 moves along the guide rails 4 and stops facing a predetermined parking room 6. To do.

(2) The electromagnetic clutch 42 is operated to disconnect the interlocking shafts 24A and 24B from the drive gear 43, and the transmission gear 4
6 is in an idle state. Then, the connecting jack 48 is operated to contract the output rod 48a, and the swing arm 44 is rotated in the direction of arrow A to project the transmission gear 46 toward the passive gear 53 side.

(3) When the idle roller 47 comes into contact with the idle roller 54, the connection jack 48 is stopped, and this contact is detected by the transmission gear 46 according to the detection values of the thrust detector and the movement amount detection sensor of the connection jack 48. Make sure that the passive gear 53 meshes correctly.

At this time, the transmission gear 46 is in the idle state,
Moreover, the transmission gear 46 moves in the arc direction to move the passive gear 53.
Therefore, when the tooth tip shifts from the passive gear 53, the transmission gear 46 rotates to move to the proper meshing position, so that proper meshing is performed, and the crests and crests of the teeth abut against each other. It rarely disappears. .
Further, since the transmission gear 46 is in the idling state, the passive gear 53 is not rotated to operate the slat conveyors 11A and 11B on the unloaded side during the meshing or disengaging operation.

(4) When the idle roller 47 is not in contact with the receiving idle roller 54 and meshing cannot be confirmed, the transmission jack 46 is moved backward by the connecting jack 48,
After deactivating the electromagnetic clutch 42 and slightly actuating the conveyor drive motor 29 to rotate the transmission gear 46 by about 1/2 pitch, the above operation is repeated.

(5) The electromagnetic clutch 42 is deactivated, the interlocking shafts 24A and 24B are connected to the drive gear 43, and the conveyor drive motor 29 is activated to operate the slat conveyor 10.
Drive A and 10B to drive the car to the slat conveyor 10
Transfer from A and 10B onto the slat conveyors 11A and 11B in the parking room 7 via the auxiliary rollers 35 and 36.

(6) The connecting jack 48 is operated to rotate the swing arm 44 in the direction of the arrow B, and the transmission gear 46 is retracted to be disengaged from the passive gear 53. According to the above example,
Since the idle roller 47 and the receiving idle roller 54, which have the same shape as the pitch circles of the transmission gear 46 and the passive gear 53 to be meshed with each other, are provided on the same axis center as the gears 46 and 53, respectively, the idle roller 47 and the receiving idle roller 54 By projecting the transmission gear 46 until they contact each other, both gears 46 and 53 can be brought into a proper meshing state in which the backlash is always constant, and the thrust detector provided in the connecting jack 48 and the movement amount. The detection sensor may be used for confirmation of meshing. Therefore, it is possible to achieve the meshing in a short time, as compared with the conventional case where the gears are meshed while confirming the position by a limit switch or the like. Moreover, since the transmission gear 46 is engaged in the free running state by moving it in the arc direction, the rate of engagement in one operation is extremely high, and the gear engagement is more accurate than in the fixed state or the linear movement. It can be performed.

Further, the interlocking shafts 24A and 24B and the drive gear 4
Since the transmission gear is engaged and disengaged while the transmission gear is in an idle state by the electromagnetic clutch 42 interposed between the transmission gear 4 and the transmission gear 4, the transmission gear 4 moves along the arc path to engage or disengage.
6, the passive gear 53 or the transmission gear 46 does not rotate to move the slat conveyors 10A, 10B, 11A, 11B.

Further, since the power transmission device 41 is provided on the interlocking shafts 24A and 24B between the slat conveyors 10A and 10B, it is not necessary to extend the shaft as compared with the conventional device provided outside the slat conveyors. In addition, even if the traveling carriage 5 tilts with respect to the transport direction due to the play between the traveling wheels 23 and the guide rail 4, the power transmission device 41
Is located in the center of the vehicle body frame 21, the displacement of the power transmission device 41 can be reduced and the transmission gear 46
And the passive gear 53 can be accurately meshed.

[0024]

As described above, according to the power transmission device of the present invention, the idler roller having the same diameter as the pitch circle is provided for the transmission gear and the passive gear to be meshed with each other. The meshing can be realized and can be confirmed by the meshing detector of the moving device, which eliminates the need for stepwise projection and confirmation as in the conventional case, and can shorten the time required for gear meshing. In addition, since a clutch that idles the transmission gear is provided, by engaging and disengaging the transmission gear in an idle state, it is possible to easily engage the transmission gear and the passive gear, and to make arcs when engaging and disengaging the gear. There is no need to operate the conveyor device on the unloaded side by eliminating the rotation of the gear caused by the movement in the direction.
