Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-story parking lot in which parking floors for parking a car are vertically stacked.

[0002]

2. Description of the Related Art As a multistory parking lot, for example, there is a pallet system. In this pallet method, a car is placed on a pallet when loading and unloading, and is carried into and out of a parking floor on each floor. However, with this pallet method, the more cars parked on one parking floor, that is, the larger the multi-story parking lot, the more pallets used, and the longer it takes to transport empty pallets. Therefore, there is a problem that the waiting time is long at the time of continuous entry and exit from the warehouse.

Conventionally, attention has been paid to such a problem, and a conveyor-type multi-story parking lot that does not use a pallet has been proposed, for example, as disclosed in Japanese Patent Laid-Open No. 5-239951.

In this conveyor type multi-story parking lot, a traveling passage is provided at the center of each parking floor, and a traveling vehicle is disposed in the traveling passage, and a traveling vehicle is disposed on both sides of the traveling passage in the traveling direction of the traveling vehicle. A vehicle storage unit is provided along. Each of the vehicle storage units is divided into a plurality of parking floors along the traveling direction of the traveling vehicle, and one position of the parking floor is used as a space for elevating the elevator platform of the automobile elevator device. It is used, and can be transported to a parking floor intended for an automobile by the elevator.

[0005] A slat conveyor for front wheels and a slat conveyor for rear wheels are arranged in pairs on the traveling vehicle. The transport directions of the two conveyors are respectively oriented in the vehicle width direction of the traveling vehicle, that is, in the direction orthogonal to the traveling direction. Further, the drive sprockets of both conveyors are operatively connected to a drive motor mounted on the traveling carriage, and the drive motors drive the two conveyors.

A pair of front wheel slat conveyors and a rear wheel slat conveyor are arranged on each of the parking floors. However, there is no drive motor for driving the slat conveyor in each parking floor.

Instead, a transmission mechanism is provided for transmitting the driving force of the driving motor provided on the traveling vehicle to the slat conveyor of the target parking floor. This eliminates the need for installing a drive motor for each parking floor.

Next, a conventional transmission mechanism disclosed in Japanese Patent Application Laid-Open No. Hei 5-239951 will be described with reference to FIG. An example of a parking lot provided with a transmission mechanism described below is referred to as a first conventional example.

A driving gear 82 is fixed to an interlocking shaft 83 of a driving sprocket of a conveyor provided on the traveling carriage 80. As a result, the drive gear 82 is linked to the drive motor provided on the traveling vehicle 80 through the link shaft 83. Here, the drive gears 82 are arranged at both ends in the vehicle width direction of the traveling vehicle 80.

An intermediate portion of a swing arm 84 is supported on both axial sides of the drive gear 82 so as to be vertically swingable. A transmission gear 85 is rotatably supported at one end (upper end) of the swing arm 84, and the transmission gear 85 meshes with the drive gear 82 in a planetary gear state. The other end (lower end) of the swing arm 84
Is connected to a tip of a rod 86a of a jack device 86 fixed to the traveling vehicle 80. When the rod 86a of the jack device 86 expands and contracts, the swing arm 84 swings up and down. Following this, the transmission gear 85 maintains the state meshed with the drive gear 82 while maintaining the state. It swings up and down about the interlocking shaft 83, and moves forward and backward in the vehicle width direction of the traveling vehicle 80.

Here, components constituting the transmission mechanism such as the transmission gear 85 and the jack device 86 are independently provided at both ends in the vehicle width direction of the traveling vehicle 80. FIG.
3, only one of them is shown.

In each parking floor 81, a passive gear 87 is provided at a position where the passive gear 87 can face the drive gear 82 of the traveling vehicle 80. The rotation shaft 87a of the passive gear 87 is
The transmission gear 8 is linked to the conveyor on the parking floor 81 side.
5 can be transmitted to the conveyor.

When the vehicle is stored, the traveling vehicle 80 loaded with the vehicle on the conveyor is driven to the position of the target parking floor 81 to determine the direction of conveyance of each conveyor on the traveling vehicle 80 side. The transport direction of each conveyor on the side of the target parking floor 81 is matched. In this state, the drive gear 82 faces the passive gear 87.

Next, the rod 86a of the jack device 86 of the two jack devices 86 provided at both ends in the vehicle width direction of the traveling vehicle, which is located on the side of the parking floor for storing the automobile, is contracted to swing. The arm 84 is swung downward from above. As a result, the transmission gear 85 supported by the swing arm 84 is displaced toward the parking floor 81 while swinging downward, and meshes with the passive gear 87 from above.

When the drive motor is operated in this state, the drive force drives the conveyor on the traveling vehicle 80 side, and the slats on the upward side of the conveyor move to the target parking floor 81 side, The driving force transmitted to the driving gear 82 through the interlocking shaft 83 is transmitted to the passive gear 87 via the transmission gear 85, and the conveyor on the parking floor 81 side interlockingly connected to the passive gear 87 also operates in synchronization. .
As a result, the vehicle on the conveyor on the traveling trolley 80 is transferred to the conveyor on the parking floor 81 side and stored in the parking floor 81.

When the vehicle stored in the parking floor 81 is transferred to the traveling bogie 80, the same operation as described above is performed so that the driving force can be transmitted to the conveyor on the parking floor 81, and then the parking operation is performed. Do.

In the transmission mechanism described in JP-A-5-239951, a clutch device is provided on the interlocking shaft 83 at a position between the driving sprocket of the conveyor on the traveling bogie side and the driving gear 82. . And the transmission gear 8
When the gear 5 is swung and meshed with the passive gear 87, the clutch is actuated to bring the transmission gear 85 into the idle state with a small load, that is, the transmission gear 85 is rotated only by applying a small force. And the transmission gear 8
5 and the probability of meshing with the passive gear 87 are increased.

As a conventional transmission mechanism, for example,
There is one described in JP-A-8-232496 and the like. An example of a parking lot provided with a transmission mechanism described below is referred to as a second conventional example.

In this transmission mechanism, a movable frame that moves forward and backward in the vehicle width direction of the traveling vehicle is disposed on the traveling vehicle. Power transmission rollers are provided at both ends of the movable frame, and the rollers are interlocked with a drive motor for driving a conveyor provided on the traveling vehicle. Also,
Each parking floor is provided with a driven roller that can be pressed against the power transmission roller, and the roller is interlocked with a conveyor of the parking floor.

Then, the power transmission roller is pressed against the driven roller by moving the movable frame toward the driven roller. Thus, the power transmitted to the power transmission roller is transmitted to the driven roller and further to the intended conveyor of the parking floor by frictional transmission.

[0021]

However, in the first conventional multi-story parking garage, the transmission gear 85 is disposed above the driving gear 82 and the passive gear 87, that is, at a position higher than the upper surface of the slat conveyor. Need to be done.
At this time, since the lowest ground clearance of the vehicle mounted on the traveling vehicle 80 differs depending on the type of the vehicle, the loaded load, and the like, the driving position is set so as not to interfere with the lower body of all the vehicles loaded on the traveling vehicle 80. It is necessary to dispose the gear 82 and the like, and the degree of freedom in disposing the drive gear 82 and the like is limited.

The transmission gear 85 needs to mesh with the driving gear 82 and the passive gear 87 arranged on the left and right from the upper side to mesh with the two gears 82 and 87, so that this meshing state is maintained. In order to achieve this, it is necessary to increase the driving force of the jack device 86 or to design the moment arm (the portion from the swing center of the swing arm 84 to the connecting portion with the rod) to be long. To increase the driving force, it is necessary to increase the size of the jack device 86. In addition, when the moment arm is lengthened, the transmission gear 85 must be swung in the vertical direction without fail. Therefore, the swing arm 84 that is arranged obliquely in the vertical direction must be designed longer. I have to help.
Further, to set a large pressing force to be applied to the transmission gear 85 meshed with the driving gear 82 and the passive gear 87 requires that the body frame and the like be correspondingly designed.

Here, in the description of Japanese Patent Publication No. 6-89607, the transmission gear 85 is divided into the drive gear 82 and the passive gear 8.
7 is described below, but in this case, the traveling vehicle 85 is arranged below the driving gear 82 and the traveling bogie is pivoted up and down by an amount corresponding to the vertical movement of the transmitting gear 85. I have to design the height of 80 high.

Further, since the body frame is usually installed at the end of the traveling vehicle 80 in the vehicle width direction along the traveling direction of the traveling vehicle 80, the body frame and the rod 86a interfere with each other, thereby causing the jack. Rod 86 of device 86
The arrangement of a becomes difficult. For this reason, Japanese Patent Laid-Open No.
As described in JP-A-239951, the transmission gear 85 is actually arranged above the drive gear 82.

Further, in the above-described mechanism for transmitting the driving force to the conveyor on the parking floor 81 side, the driving force of the driving gear 82 is always independently transmitted on both sides of the traveling vehicle 80 to the passive gear 87. Transmission gear 85 and jack device 86 must be provided.

In the transmission mechanism of the second conventional example, since power is transmitted by frictional transmission between the power transmission roller and the driven roller, power transmission may be insufficient due to slippage. Further, in order to sufficiently transmit power, it is necessary to press the power transmission roller against the driven roller with a large pressing force so that a large pressing force is generated. For this reason,
It is necessary to increase the size of a cylinder device and the like for moving the movable frame supporting the power transmission roller.

Further, if the pressing force is large, the body frame and the like may be bent and a sufficient pressure contact force may not be obtained. Therefore, the body frame may be strengthened or the hook described in Japanese Patent Application Laid-Open No. 8-232496 may be used. It is necessary to take measures such as temporarily connecting the frames near the power transmission roller and the driven roller with a mechanism or the like.

The present invention focuses on the above-mentioned problems, and does not provide an upwardly protruding portion or the like on a traveling vehicle, does not generate a large pressing force, and reliably uses a simple mechanism. It is an object of the present invention to provide a multi-story parking garage in which a driving gear on a traveling trolley can mesh with a passive gear.

[0029]

In order to solve the above-mentioned problems, a multi-story parking lot according to a first aspect of the present invention is provided with a traveling passage on which a traveling vehicle travels on each parking floor and along the traveling passage. And arranging a plurality of parking floors, and arranging a conveyor capable of transferring a vehicle between the traveling carriage and each parking floor, respectively, so that the conveyor on the traveling carriage is a self-propelled type. In the multi-story parking lot driven by the driving force of the rotary drive device provided on the traveling cart, the respective conveyors on the parking floor side are connected to the respective conveyors on the parking floor side in conjunction with the respective parking floors. A driving gear provided on the traveling vehicle, the driving gear being interlockingly connected to the rotary driving device and being disposed at a position capable of facing the passive gear and meshing with the passive gear; and a drive supporting the driving gear. Gear support and its A support driving device for moving the dynamic gear support toward or away from the passive gear, and a rotation imparting means for rotating the drive gear when the drive gear advances toward and meshes with the passive gear; And a pressing force restricting means for restricting a pressing force applied to the driving gear in contact with the passive gear to a predetermined value or less.

According to the present invention, the drive gear moves closer to the passive gear and then the passive gear by operating the support driving device to linearly advance the drive gear support toward the passive gear. Mesh with. This allows the driving force of the rotary drive to be transmitted directly from the drive gear to the passive gear.

At this time, since the power is transmitted to the parking floor side by the meshing of the gears, the power can be transmitted reliably unlike the friction transmission by the rollers. Further, since the power is transmitted by the meshing of the gears, the pressing force of the drive gear against the passive gear is much smaller than the power transmission by the rollers.

Here, unlike the case where the power is transmitted by pressing the rollers, it is necessary to reliably engage both gears. In the present invention, a configuration is adopted in which the drive gear is brought close to the passive gear while rotating so as to be engaged with the passive gear, even if the tooth tips of both gears abut when the two gears mesh with each other. The force generated between the two gears is regulated by the pressing force regulating means. In this state, the driving gear is rotationally displaced by the rotation torque by the rotation imparting means, and the tooth tip of the driving gear is displaced from the tooth tip of the passive gear. The gears reliably engage the passive gears.

Here, the driving gear moves toward the passive gear by the driving force of the support driving device, but the contact pressure between the two gears in contact is regulated by the pressing force regulating means as described above. Therefore, even if the tooth tips of both gears are in contact with each other, it is possible to easily adjust the contact pressure to such an extent that the drive gear can be rotationally displaced.

This is because the force generated between the two gears at the time of meshing and after the meshing is prevented by the pressing force regulating means from being excessive, and power is transmitted to the parking floor. There is no need to make the frame of the traveling vehicle strong, which leads to a reduction in size and weight of the traveling vehicle.

Next, a second aspect of the present invention is characterized in that, in the configuration of the first aspect, the rotation applying means comprises the rotation driving device. According to the present invention, not only when the driving force is transmitted to the conveyor on the parking floor side via the meshed drive gear and the passive gear,
Even when the driving gear is meshed with the passive gear, the driving force is transmitted to the driving gear to apply a rotating torque to the driving gear before meshing, so that the rotation driving device constitutes a rotation applying unit.

Next, according to a third aspect of the present invention, in accordance with the structure of the first or second aspect, the rotary drive device comprises a conveyor drive device for driving a conveyor on a traveling bogie side; A driving pulley interlockingly connected to the conveyor driving device, a transmission pulley interlockingly connected to the driving gear, a belt wound between the driving pulley and the transmission pulley, and slack removal for removing slack of the belt. Means.

Here, the slack removing means can be realized, for example, by providing two driving gears at both ends of the driving gear support in the reciprocating direction and providing two sprockets which move synchronously. This is realized by providing a separate tensioner.

The pulley includes a sprocket, and the belt includes a timing belt and a chain belt. Then, for example, by using a sprocket as the pulley and using a chain belt as the belt, it is possible to reliably prevent slippage during transmission and suppress deterioration of transmission efficiency.

In the multistory parking lot of the present invention, it is necessary to move the drive gear forward and backward in the vehicle width direction. However, by transmitting the power by chain transmission, the position of the rotary shaft of the drive side sprocket can be changed. Thus, the driving force can be transmitted to the driving gear that moves forward and backward reliably.

At this time, when the driving gear is brought closer to the passive gear and meshed with the driven gear, the driving force of the rotary driving device is transmitted to the driving gear in synchronization, whereby the driving gear rotates. When the driving force is not transmitted from the rotary driving device to the driving gear, the driving sprocket is in a non-rotating state, that is, a state in which the chain belt does not circulate. Therefore, when the drive gear moves and the transmission sprocket linked to the drive gear moves, the transmission sprocket relatively rotates by meshing with the non-circulating chain belt, and the drive gear rotates.

Next, the invention described in claim 4 is the same as the structure described in any one of claims 1 to 3, except that
The pressing force restricting means comprises urging means for urging the driving gear supported by the driving gear support toward the passive gear in a state in which the driving gear can retreat in a direction away from the passive gear. Is what you do.

According to the present invention, when the driving gear approaches the passive gear and comes into contact with the passive gear by the driving force of the support driving device, the force for pressing the driving gear against the passive gear is adjusted by the urging force of the urging means. Be regulated.

When the drive gear approaches the passive gear and meshes with the passive gear, if the tooth tips of the two gears come into contact with each other, the force generated between the two gears is biased as described above. The driving gear is retracted relatively to the base point of the urging means (the forward gear is stopped when viewed from the passive gear side), and then the driving gear swings. If the tooth tips of both gears that were in contact with each other due to dynamic displacement were shifted,
The driving gear moves forward by the urging force of the urging means and reliably meshes with the passive gear. Next, according to a fifth aspect of the present invention, in the configuration according to any one of the first to fourth aspects, the drive gear is interlockingly connected to a conveyor driving device that drives the conveyor on the traveling bogie side. In addition, the conveyor driving device and the conveyor on the traveling trolley are interlocked and connected via a clutch.

According to the present invention, the transmission of the driving force from the conveyor driving device to the conveyor on the traveling vehicle is disconnected by operating the clutch device, thereby independently of the driving of the conveyor provided on the traveling vehicle. Thus, power can be transmitted to the drive gear. That is, the drive gear can be rotated with a small load.

Further, at this time, since no power is transmitted to the conveyor on the traveling vehicle side, the position of the vehicle on the conveyor does not needlessly shift. When the clutch device is operated to connect the conveyor driving device to a driving sprocket or the like of the conveyor on the traveling vehicle side, the conveyor provided on the traveling vehicle and the driving gear are driven synchronously.

Next, according to a sixth aspect of the present invention, in the configuration according to any one of the first to fifth aspects, the conveyor on the side of each of the parking floors extends along an endless belt. It is a slat conveyor in which slats are provided only at some positions and only at positions where wheels of an automobile to be loaded can be placed.

The weight of the slat conveyor on the parking floor side is reduced, and the load on the rotary drive device for rotating and driving the slat conveyor on the parking floor side is reduced. Next, according to a seventh aspect of the present invention, in the configuration according to any one of the first to sixth aspects, the rotating shaft of the drive gear and the rotating shaft of the passive gear are configured such that the meshing of the two gears is performed. In this case, the drive gears are offset from each other when viewed from the direction of movement of the drive gear.

According to the present invention, by offsetting the rotation axes of both gears as described above, when the drive gear moves forward and the drive gear contacts the passive gear, the drive gear and the passive gear are connected to each other. Since the normal direction of the above-mentioned contact and the forward direction of the drive gear are different, by appropriately selecting the rotation direction of the drive gear, the tooth tip of the drive gear and the tooth tip of the passive gear are easily displaced even if they come into contact with each other. Become.

Next, according to the invention described in claim 8, the conveyor on the traveling trolley side is different from the structure described in any one of claims 1 to 7 in that sprockets at both ends in the extending direction are provided. Are drive sprockets, and a conveyor drive device for driving the conveyor on the traveling trolley side is interlockedly connected to the two drive sprockets.

According to the present invention, since the driving torque is transmitted to both sprockets at both ends in the extending direction, the conveyor is prevented from becoming loose even when the conveyor on the traveling bogie is rotated forward or backward. You.

6 has a structure as shown in FIG. 9 which is a sectional view seen from above and FIG. 10 which is seen from the vehicle width direction. That is, the slider 37 is supported between the pair of brackets 36 so as to be vertically swingable. The slider 37 has a through hole 37 a whose axis is oriented substantially in the vehicle width direction of the traveling vehicle 3.
Is opened, and the piston rod 35b is relatively inserted into the through hole 37a, so that the slider 37
Is guided by the piston rod 35b and is movable only in the axial direction of the piston rod 35b.

Further, with respect to the piston rod 35b,
A pair of cylindrical members 38 are fixed with the slider 37 interposed therebetween. Each cylindrical member 38 is a cylindrical member 38 with a bottom, which is disposed coaxially with the axis of the piston rod 35b, and has an opening thereof facing the slider 37 at a predetermined interval.

Then, a guide member 37b having a cross section substantially equal to the cross section of the inner diameter of the cylindrical member 38 projects coaxially from the slider 37 toward each of the cylindrical members 38, and the tip end of each guide member 37b is It is coaxially inserted into the corresponding cylindrical member 38. Further, the guide member 37
A coil spring 39 is interposed between b and the bottom of the cylindrical member 38, respectively.

With the above configuration, the slider 37 is regulated to a predetermined position on the piston rod 35b by the biasing force of the pair of springs. Here, the slider 3
7, the pair of cylindrical members 38, and the coil spring 39 constitute a pressing force regulating unit and a biasing unit.

Further, the front wheel conveyor 9 and the rear wheel conveyor 10 provided on each parking floor 5 have the same configuration as the conveyors 7 and 8 provided on the traveling carriage 3.
That is, the conveyors 9 and 10 of the parking floors 5 extend in the direction of conveyance in the width direction of the traveling vehicle 3, and the rotating shaft 40 of the driving sprocket 40 of the conveyors 9 and 10.
“a” is an end on the side of the traveling passage 2 and extends in the traveling direction of the traveling vehicle 3. The rotating shafts 40a of the driving sprockets 40 of the conveyors 9 and 10 are integrally connected,
When the driving force is transmitted to the front wheel conveyor 9, the operation is synchronized with the operation of the front wheel conveyor 9 and the rear wheel conveyor 10 is transmitted.
Also works.

A passive gear 41 is coaxially fixed to a rotating shaft 40a of a driving sprocket 40 of the conveyors 9, 10 provided on the parking floor section 5. When the transport direction of the conveyors 7, 8 of the traveling vehicle 3 is matched with the transport direction of the conveyors 9, 10 of the parking floor 5, the passive gear 41 drives the driving gear 32 on the traveling vehicle 3 side in the vehicle width direction. Is disposed at a position opposite to the above. That is, the drive gear 32 is arranged so as to be relatively movable toward or away from the passive gear 41. However, the height of the rotating shaft 41a of the passive gear 41 is slightly
It is set to be higher than the height of 2a by offsetting by δ vertically (see FIG. 8). By setting as described above, the opposing direction of the drive gear 32 and the passive gear 41 becomes the vehicle width direction of the traveling vehicle 3.

Here, the slat conveyors 9 and 10 provided on the parking floor 5 are provided with slats only in half of the conveyors 9 and 10 arranged in an endless ring along the chain belt 42. That is, for example, if all the slats are located on the downside of the conveyors 9 and 10,
As shown in FIG. 12 described later, there is no slat between the chain belts 14 on the upward side.

In FIG. 3, reference numeral 43 denotes the traveling vehicle 3
The roller 43 is rotatably supported by the vehicle body frame 3a, and the roller 43 is located above a portion where the conveyors 7, 8 are converted from upward to downward.

In FIG. 3, reference numeral 44 denotes a traveling rail for the traveling carriage 3, and reference numeral 45 denotes the traveling rail 44.
Reference numeral 46 denotes an auxiliary vehicle that is supported by the traveling vehicle 3 and contacts the rail 44 from the side.

Further, the traveling carriage 3 has an automobile presence / absence confirmation sensor for confirming whether or not a car is stored in the parking floor 5, an automobile passage confirmation sensor for confirming whether or not a car to be transported passes between conveyors, To the traveling trolley 3
Sensors for guiding the vehicle 3 to a fixed position on the parking floor 5 and a traveling switch 3 for stopping the traveling vehicle 3 at a predetermined position in front of each parking floor 5 and the elevator 6a of the elevator apparatus. Three positioning sensors and the like are provided.

Further, a sensor comprising a photoelectric tube or the like for detecting the slat position of each of the conveyors 9 and 10 of the parking floor 5 is provided, and the slat conveyor 9 disposed on the target parking floor 5 from the traveling vehicle 3 side. , 10 slat positions can be detected. Further, a sensor for detecting normal engagement between the drive gear 32 and the passive gear 41 is provided.

Next, a case where a car is stored in the parking floor 5 in the multi-story parking lot having the above configuration will be described. First, after the automobile is moved and placed on the elevator 6a of the elevator device 6, the elevator 6a is lowered to move to the target parking floor 1. At this time, the traveling cart 3 on the parking floor 1 is made to stand by before the elevator.

Next, the elevators 6 a and the conveyors 11, 12, 7, 8 provided on the traveling carriage 3 are driven to drive the elevators 6 a
The upper car is transferred to the traveling trolley 3 side. When the transfer of the vehicle is completed, the conveyors 11, 12, 7, and 8 are stopped, and the traveling cart 3 is moved to the front of the intended parking floor 5.

Next, the drive motor 17 is operated with the clutch 20 in the disengaged state. Then, the driving force of the driving motor 17 is transmitted to the driving sprocket 28 via the driving shaft 18, and the driving force transmitted to the driving sprocket 28 is transmitted to the transmission sprocket 29 by chain transmission, and further transmitted to the transmission sprocket 29. Driving force is transmitted to a drive gear 32 connected to 29, and the drive gear 32 rotates.

Here, the parking floor 5 for storing the car is
The parking floor portion 5 on the lower side in FIG. When the piston rod 35b is retracted by operating the cylinder device 35 in the above state, the support rod 33 connected to the piston rod 35b becomes
After moving horizontally to the target parking floor 5 side, one drive gear 32 approaches the opposing passive gear 41 and subsequently meshes.

Here, the stroke amount of the piston rod 35b is set such that the drive gear 32 transmits to the passive gear 41 facing the standby position from the standby position. C. D. Is set to the distance to the meshing position. Even if the stroke amount is set to be slightly larger, the pressing force applied from the drive gear 32 to the passive gear 41 can be controlled by the coil spring 39 of the urging means.
Therefore, the pressing does not become excessive.

When the drive gear 32 moves horizontally and meshes with the passive gear 41 as described above, as shown in FIG. 11, the tooth tips of the drive gear 32 and the passive gear 41 contact each other. In this case, the piston rod 35b retreats until a predetermined stroke is reached, but the retraction is absorbed by the contraction of the coil spring 39, and the drive gear 32 relatively retreats (stops when viewed from the passive gear 41). by this,
The force generated between the drive gear 32 and the passive gear 41 is regulated by the urging force regulated by the col spring 39. That is, the contact pressure between the tooth tip of the driving gear 32 and the tooth tip of the passive gear 41 in contact with each other is regulated by the coil spring 39 so as not to exceed a predetermined value.

At this time, since the rotational torque is transmitted to the drive gear 32, the drive gear 32 overcomes the pressing force regulated by the urging force, and the drive gear 32 is rotationally displaced and the two gears 32,
At the same time as the tooth tip of 41 is shifted and the tooth tip is shifted, the drive gear 32 advances toward the passive gear 41 by the urging force regulated by the coil spring 39 and meshes with the passive gear 41.

At this time, the conveyors 7 and 8 on the traveling trolley are not driven during the connecting operation, so that the positions of the vehicles mounted on the conveyors 7 and 8 on the traveling trolley may be inadvertently shifted. Be avoided.

Further, since the driving gear 32 and the passive gear 41 are vertically offset by δ, the meshing becomes easier by setting the rotation direction of the driving gear 32 appropriately.

Thus, the rotational torque is reliably transmitted from the driving gear 32 to the passive gear 41, and the driving sprockets 40 of the conveyors 9 and 10 on the parking floor 5 side connected to the passive gear 41 are rotationally driven.

Here, as the drive gear 32 advances and retreats, the transmission sprocket 2 connected to the drive gear 32
9 also advances and retreats in the vehicle width direction, but the pair of drive gears 32 move in the same direction in synchronization with each other and the drive side sprocket 2
Since the transmission sprocket 29 and the transmission side sprocket 29 are connected by the chain belt 30, the rotation speed of the transmission side sprocket 29 follows the rotation of the drive side sprocket 28 although the rotation speed slightly changes during movement. The driving force is reliably transmitted to the driving gear 32.

Subsequently, the drive gear 32 is rotated forward and reverse to
The positions of the slats provided on the slat conveyors 9 and 10 of the parking floor section 5 are adjusted so that the wheels of the moving automobile can be reliably mounted on the slats of the conveyors 9 and 10.

For example, as shown in FIG. 12, almost all the rows of slats 50 are located on the downside, and the slats 50a located at the end thereof are moved upward at a position facing the traveling carriage 3 side. Adjust to the position where it turns to the side. When one car is already loaded on the conveyors 9 and 10, the substantially center position of the slat row 50 is set to the upward turning position at a position facing the traveling car 3.

Next, the clutch 20 is operated, that is, the coil 23 of the clutch 20 is energized to attract the movable body 22 to the clutch body 21 side.
And the conveyor drive sprocket 19 is connected to the drive shaft 18. Thereby, the driving force of the drive motor 17 can be transmitted to the conveyors 7 and 8 on the traveling trolley 3 side, and at the same time, can be transmitted to the conveyors 9 and 10 of the parking floor 5 through the drive gear 32 and the passive gear 41. .

Then, when the drive motor 17 is operated in this state, the conveyors 7 on the traveling carriage 3 side and the parking floor section 5 side,
When the vehicles 8, 9 and 10 are operated, the automobiles on the traveling vehicle 3 are transferred from the slat conveyors 7 and 8 of the traveling vehicle 3 to the slat conveyors 9 and 10 on the parking floor 5 side.

At this time, the conveyors 7 and 8 on the traveling carriage 3 side
There is an inverted mountain-shaped concave portion (part B in 10) in a portion facing the conveyors 9 and 10 on the side of the parking floor portion 5, but the roller 43 is disposed above the concave position. There is no possibility that the wheels of the vehicle being transferred will enter the recess.

At this time, the slats 9 and 10 are arranged on the slat conveyors 9 and 10 on the parking floor 5 side only at a half position along the endless annular chain belt 42. The load for driving is reduced accordingly, and the load when driving the conveyors 9 and 10 on the parking floor 5 side by the drive motor 17 is reduced.

Further, since the number of slats of the conveyors 9 and 10 provided in each parking floor unit 5 can be reduced to half, the construction cost of the parking lot can be reduced. When the storage of the vehicle is completed as described above, the cylinder device 35 is operated to extend the piston rod 35b to the initial position, and return the drive gear 32 to the standby position.

In the above description, the case where the car is stored is described. However, when the car is taken out of the parking floor 5, the drive gear 32 is moved to the passive gear 41 by the same operation.
After the driving force can be transmitted to the conveyors 9 and 10 on the parking floor portion side, the conveyors 9 and 10 on the parking floor portion 5 side can be transmitted.
What is necessary is just to transfer the motor vehicle mounted on 10 to the conveyors 7 and 8 of the traveling vehicle 3 side.

Here, in the case where the car is stored and the case where the car is taken out of the car as described above, the conveyor 7, 7
Although the conveyor 8 rotates forward or backward in response to this, in the present embodiment, the conveyors 7 and 8 are of a double drive system that drives the two sprockets 13 arranged at both ends in synchronization with each other, so that the forward rotation is performed. And the conveyor is prevented from loosening.

However, from the viewpoint of cost and the like, the conveyors 7 and 8 on the traveling trolley side may be of a single drive type for driving only one of the two sprockets 13 as in the conventional case. However, in this case, depending on the position of the driving sprocket, the conveyor is conveyed by pushing the conveyor in one of forward rotation and reverse rotation, and the conveyor is slightly moved when the vehicle is stored or taken out of the vehicle. It becomes loose.

In the above embodiment, in order to reduce the load and cost, the slat conveyor 9 on the parking floor 5 side is used.
Although the amount of the slats provided on the slats 10 is halved, the slats may be provided on the entire circumference along the drive chain belt 42 of the slat conveyors 9, 10.

In the above embodiment, the drive motor 17
By actuating, the drive gear 32 is horizontally moved toward the passive gear 41 while rotating the drive-side sprocket 28, but is not limited to this. For example, the support 33 may be advanced and retracted while the drive motor 17 is stopped, and one of the two drive gears 32 may be advanced toward the passive gear 41.

At this time, since the driving side sprocket 28 is fixed (non-rotating state), the chain belt 3
Although 0 does not circulate, the two driving gears 32 move horizontally, that is, the pair of transmission-side sprockets 29 move laterally in synchronization with each other, so that the transmission-side sprockets 29 move while rotating, that is, the drive gear 32 rotates. The drive gear 32 reliably engages with the passive gear 41 by the same operation as described above.

In the above embodiment, the urging means is provided at the connection position between the piston rod 35b of the cylinder device 35 and the support rod 33, but the invention is not limited to this. For example, in the support rod 33, the connecting part to the piston rod 35b and the intermediate part between both ends of each support rod 33 are nested cylindrical members movable only in the axial direction. An elastic body such as a spring may be interposed therebetween to serve as the urging means.

The pressing force regulating means is not limited to the above-mentioned urging means. For example, an actual load applied to the drive gear is detected by a load sensor or the like installed on a support rod or the like.
The pressing force control means may be configured by adopting a configuration in which the cylinder pressure or the like of the cylinder device is adjusted by a control valve or the like based on the load.

In the above embodiment, the drive gear support is constituted by the support rod 33 formed of a straight rod. However, the present invention is not limited to this. For example, the drive gear support may be constituted by a plate member or the like. In short, it is only necessary that a pair of drive gears 32 can be rotatably supported at both ends in the vehicle width direction.

Further, in the above embodiment, the cylinder device 35 is disposed below the support rod 33, but the position is not limited to this. It is not necessary to swing the transmission gear up and down as in the conventional example.
The cylinder device 35 may be arranged in the lateral direction of the support rod 33 as long as the cylinder device 35 can be moved forward and backward linearly.

Although the cylinder device 35 is disposed below the support rod 33 in the above example, it is not necessary to dispose the cylinder device 35 at the end of the traveling vehicle 3 in the vehicle width direction. Interference is avoided. Further, since the piston rod 35b and the support rod 33 of the cylinder device 35 only move forward and backward in the horizontal direction, it is necessary to increase the vehicle height as in the prior art because of the power transmission mechanism using gears as in this embodiment. Nor.

Further, the cylinder may be disposed between the support rod 33 and the cylinder gear may be disposed therebetween, or the cylinder apparatus may be a double rod type, and the drive gear may be supported at both ends of the piston rod of the cylinder apparatus. .

In the above embodiment, the case where the support driving device is constituted by the cylinder device 35 is described as an example. However, the present invention is not limited to this. For example, the support driving device may be configured by a rack and pinion method.

In the above embodiment, the drive shaft 18 and the conveyor driving sprocket 19 are connected via the clutch 20. However, the conveyor driving sprocket 19 is directly fixed to the driving shaft 18 without providing the clutch 20. May be. However, in this case, the drive gear 32 cannot be independently rotated, and the conveyors 7 and 8 always operate.

In the above embodiment, the drive motor 17 for driving the conveyors 7 and 8 on the traveling trolley is a rotary drive. However, a rotary drive may be provided separately from the drive motor 17.

Further, the clutch 20 may be provided at the position of the driving sprocket 29. In this case, for example, by operating the clutch, the connection between the drive shaft 18 and the drive-side sprocket 29 is cut to reduce the load on the drive-side sprocket 29, and the drive gear 32 is moved forward. Immediately before the drive gear 32 meshes with the passive gear 41 or when the two 32 and 41 abut, the clutch is actuated to connect the drive shaft 18 and the drive sprocket 29 and drive the drive motor 17 to drive the drive. Gear 3
With the second gear in the rotating state, the drive gear 32 and the passive gear 41 are securely engaged with each other. However, in this case, the driving gear 3
When the second gear 2 and the passive gear 41 are connected, the conveyors 7 and 8 on the traveling carriage slightly move.

[0122]

As described above, in the multistory parking lot according to the present invention, the driving gear can be used even if a driving device for driving the conveyor provided on the parking floor is not provided on the parking floor side. This is a simple mechanism of moving forward and gearing toward the passive gear to be driven, and has an effect that the driving force of the rotary drive device provided on the traveling vehicle can be reliably transmitted to the conveyor on the parking floor side.

At this time, since the moving drive gear and the drive gear support have no element that swings up and down, there is no need to protrude above the traveling vehicle, and it is not necessary to increase the height of the traveling vehicle. .

Further, even if a gear is used for the power transmission mechanism,
According to the present invention, the drive gear and the driven gear can be reliably meshed with each other, and an excessive load is applied to the body frame of the traveling bogie during the meshing and during the meshing (during power transmission). Is prevented. This leads to a reduction in the size and weight of the traveling vehicle.

Further, when the invention described in claim 2 is adopted, it is not necessary to independently provide a drive source only for the rotation applying means. In addition, when the invention described in claim 3 is adopted, the driving force can be reliably transmitted to the driving gear even if the driving gear moves forward and backward.

Also, when the pair of drive gears is moved forward and backward as described above with the drive side sprocket stopped,
Since the drive gear can be moved forward and backward while rotating, the moving drive sprocket can be surely rotated even when the conveyor on the traveling trolley is not operated.

According to the fourth aspect of the present invention, the pressing force regulating means can be realized, and when the driving gear meshes with the passive gear, the tooth of the driving gear contacts the tooth of the passive gear. Subsequently, when the drive gear is rotationally displaced and the tooth tips are displaced from each other, the drive gear can be meshed with the passive gear by the urging force of the urging means.

Further, when the invention described in claim 5 is adopted, the driving force can be transmitted only to the driving gear without driving the conveyor provided on the traveling vehicle, and the driving gear is rotated with a small load. Can be done.

For this reason, for example, the load on the rotary drive when the drive gear is driven to rotate so as to reliably mesh the drive gear with the passive gear can be reduced. In addition, independently of the conveyor on the traveling trolley, only the conveyor on the parking floor side can be driven.

Next, when the invention described in claim 6 is adopted, the load for driving the conveyor on the parking floor side is reduced, and the amount of slats used in the multi-story parking lot is reduced to about half. Cost can be reduced.

At this time, the position of the slat can be easily adjusted by combining with the invention of the fifth aspect. Next, when the invention described in claim 7 is adopted, the forward movement direction of the drive gear is different from the direction of the contact pressure due to the contact between the drive gear and the passive gear, so that the drive gear is easily rotated and displaced. Therefore, it becomes easier to mesh with the driving gear and the passive gear.

Further, when the invention described in claim 8 is employed, the conveyor on the traveling trolley is prevented from being loosened during the storing and unloading work of the vehicle, and the position of the vehicle on the conveyor can be controlled more accurately. Becomes
