The operation of the above-described embodiment will be described below. At the terminal end of the non-working route 3B, the empty carriage 10 fed from the feeding device 36 is positioned in the transfer route portion 3D on the upper feeding side. At this time, in the transfer path portion 3D, the lift device 55 is moved down and the elevating frame 57 is at the lower limit. Therefore, the empty carriage 10 is located above the contact portion 59. In this state, first, the cylinder device 58 is actuated to raise the elevating frame 57 a little, and the abutting part 59 is moved to the carriage 10.
The trolley 10 is slightly lifted from the rail 1 by abutting it on the lower surface of the trolley.

Next, the cylinder device 67 of the movable body positioning device 65 is actuated, and the clamped portion 15 is sandwiched between the clamp claws 66 from the front and the rear, whereby the carriage 10 is positioned with respect to the elevating frame 57. Then, the elevating frame 57 is raised again by the operation of the cylinder device 58. At this time, the movable rail 40 moves the elevating member 48 by the extension of the cylinder device 49.
And the cam roller 46 is positioned below the cam groove 50 to move the free ends of both arms 45 downward. Separated from the end. Therefore, the carriage via the lifting frame 57
The ascent of 10 is performed without colliding with the movable rail 40.

After the elevating frame 57 reaches the upper limit, the movable rail 40 is connected and the doors 82A and 82B are carried in. That is, the connecting movement of the movable rail 40 causes the elevating member 48 to descend due to the contraction of the cylinder device 49 and the cam roller.
46 is positioned above the cam groove 50 so that both arms 45
By swinging the free end of the rail upward and inward, as shown in the solid line in FIG. 4 and in FIG. Connect to one end. At this time, the movable rail 40 is a wheel
It is in contact with 12 from below.

The doors 82A and 82B are carried in together with the pallet 83 by the carry-in device 70. That is, the transfer path unit 3D
A hanger 81 is stopped above the table via a trolley device or the like, and the hanger 81 supports the doors 82A and 82B. In this state, the lifting body with the fork body 76 protruding
73 is lifted, and thus the hanger is passed through the object holder 77.
From 81, the doors 82A and 82B are lifted and held together with the pallet 83 as shown by the solid line in FIG.

Then, the fork body 76 is moved back and forth to the middle, and the pallet 83 and the door 82 are moved as shown by the phantom line A in FIG.

The doors 82A and 82B can be lowered by lowering the lifting / lowering body 73, so that the doors 82A and 82B can be passed to the support portion 13 via the pallet 83, as shown by the phantom line B in FIG. After that, the fork body 76 is completely retracted, and then lifted together with the lifting body 73.

In the above description, the doors 82A and 82B are transferred at the same time in the pair of fixed paths 3. However, this is because the lift devices 55 are individually operated to cause a timing shift.

After carrying in the doors 82A and 82B in this manner, the positioning by the movable body positioning device 65 is released. Then, the carriage 10 is pushed into the front end portion of the work path portion 3A by the operation of the movable body moving device 60, and is stopped when the front end enters the feeding device 20. Here, the movable body moving device 60 moves the carriage 10 by operating in the same manner as the feeding device 20 described later in a state where the feeding device 20 side is in a receiving posture. At that time, on the rear contact surface 16 of the rearmost carriage 10 of the carriage 10 group positioned in the work route portion 3A in the form of a dense train,
The front contact surface 16 of the trolley 10 that has been fed into contact with the trolley 10 moves, whereby the trolley 10 group is moved by the feeding force of the movable body moving device 60.

Movement (carry-in) by the movable body moving device 60

At this time, the cylinder device 27 of the feeding device 20 is extended to swing the support member 24 outward about the longitudinal axis, so that the feeding roller 26 is separated from the pressure receiving portion 14. Therefore, the carriage 10 can be moved without any trouble.

After loading, the feed roller 26 is moved closer to and brought into pressure contact with the pressure receiving portion 14 by the action opposite to that described above. At this time, both feed rollers 26 are rotationally driven by the servomotor 25. Therefore, by forcing the feed roller 26, which is being forcedly rotated, into pressure contact with the pressure receiving portion 14, the feed rotational force A imparts a moving force to the carriage 10, so that the carriage 10 moves at a desired speed on the work path portion 3A. Is moved E, and the group of trolleys 10 located in a dense train on the work route portion 3A is pushed and moved.

After the carriage 10 is sent to the work path portion 3A, the elevating frame 57 moves to the lower limit as described above. The trolley | bogie 10 which has reached the lower side of the work path part 3A is being braked by the braking device 30. That is, when the movement of the carriage 10 by the feeding device 20 is stopped, the braking device
The cylinder device in 30 is contracted, so that the braking roller 31
Are separated from each other. Then, interlocking with the movement of the feeding device 20, both braking rollers 31 are moved closer to each other and brought into pressure contact with the pressure receiving portion 14 by the action opposite to the above, but at this time, the braking roller 31 is opposite to the feeding roller 26. It is driven to rotate to the side. That is, both braking rollers 31 are forcibly rotated in opposite directions by driving the torque motor.

Therefore, the braking roller that is forcibly rotated
When 31 is brought into pressure contact with the pressure receiving portion 14, a reverse moving direction force acts on the carriage 10 by the reverse feed rotational force B, but since the feed rotational force A is larger than the reverse feed rotational force B here, According to the difference, the braking roller 31 is rotated to the feed rotation side,
The load at that time is absorbed by the torque motor.

As a result, the carriage 10 corresponding to the lower braking device 30 is conveyed while being subjected to the braking action. Therefore, between the feeding device 20 and the braking device 30, a plurality of carriages 10 are They are densely aligned in the rearward pushing state without forming a gap between the front and rear ends thereof. The braking action of the braking device 30 is stopped before or after the movement of the feeding device 20 is stopped.

That is, the dolly 10 is received by the movable rails 40, 40A, 40B in the transfer path portion 3C, and is stopped at a fixed position by the operation of the movable body moving device 60 of the lift device 55, and then is supported by the unloading device 71. Door from 13
82A and 82B are carried out together with the pallet 83.

The doors 82A and 82B are used for the suspension conveyance device 80.
The pallet 83 is handed over to the hanger 81 and the empty trolley 10 is lowered to the descent limit at the transfer path portion 3C through the space between the movable rails 40 which are swung downward and outward. Then, the empty carriage 10 is passed over the rails 1 of the non-work route portion 3B via the wheels 12 thereof. In the non-work path portion 3B, the carriage 10 is not present and is empty, and the stopper device 39 is in the stopper posture.

Next, the empty carriage 10 is a movable body high speed moving device.
It is moved by the operation of 62. That is, the feed rollers 64 are moved toward each other and brought into pressure contact with the pressure receiving portion 14, and at this time, both feed rollers 64 are rotationally driven at high speed by the servo motor 63. Therefore, by the high-speed feed torque D
Since the moving force is given to the carriage 10, the carriage 10 is returned at a high speed on the non-work route portion 3B.

In this way, the carriage 10 returned at high speed gradually decreases in speed, and enters the space between the speed reducers 36 by the lower portion on the non-work path portion 3B. Here, the air motor 37 is
A dolly that is normally in a non-rotating state and has moved at high speed
The pressure receiving portion 14 of 10 enters between the deceleration rollers 38 and comes into pressure contact therewith.
Then, with the moving force of the carriage 10, air is discharged while rotating the deceleration roller 38, and thus the movement energy is absorbed to absorb the movement energy.
To slow down rapidly. After that, the abutment surface 16 of the front portion of the carriage 10 is received by the stopper body of the stopper device 39 and stops.

Then, by operating the braking device 30 in a state where the stopper body of the stopper device 39 is retracted, the carriage 10 is sent out, and the abutting part 59 at the lower limit of the transfer path part 3D on the upper transfer side is sent. Is positioned above, and is fed by the elevation of the elevating frame 57 as described above.
