After that, the lifter mechanism 8 moves the cart mounting base 7 downward, and while the box group A is mounted and supported on the cart b, the cart b
Return to the lower limit position.

When the detector detects that the lifter mechanism 8 has returned to its lower limit position, the operation of the lifter mechanism 8 is stopped, the doors 15 and 15 are opened, and a cart unloading command is issued to the cart unloading device 4 to unload the cart b.

When the detector detects the unloading of the trolley b, the opening/closing mechanism 13 is closed to return the conveyors 6, 6' to the closed position, and the doors 15, 15 are closed.
Doors 15', 15' are opened.

When the initial return of the opening/closing mechanism 13 is detected, all operations are stopped and the system waits until the next box group carry-in command is issued, and the process operation is repeated in response to the next command.

The operation of the cart unloading device 4 will be explained with reference to FIGS. 12 to 14.

While the lifter mechanism 8 is moving the cart platform 7 upward, the chain conveyors 54, 54 are driven, and when it is detected that the hanging arms 57, 57 have returned to the upper end position as shown in FIG. , the chain conveyors 54, 54 are stopped.

When the lifter mechanism 8 moves downward and stops at the lower limit position, the protruding piece 'b of the cart b is held by the hanging arms 57, 57, and in this state, the doors 15, 15 are opened and a cart unloading command is issued. and chain conveyor 5
4,54 is activated.

The hanging arms 57, 57 start moving downward while holding the cart b, and the guide rollers provided on the chains 54, 54 rotate along the sprockets 52, 52, so they are gradually accelerated, and the guide rollers move toward the sprockets. 52, 52, it moves downward at a constant speed.

Next, when the truck b is moved to the vicinity of the end of the slope, the guide roller rotates along the sprockets 53, 53 and is gradually decelerated, becoming almost zero at the moment it goes around the sprockets 53, 53.

At this time, the hanging arms 57, 57 are attached to the guide members 61, 6.
1, and when the descending speed of truck b becomes almost zero, truck b is released.

Carriage b naturally falls the remaining height, but since its height is low, it moves down at a slow descending speed.

Next, as shown in FIG. 12, the hanging arms 57, 57 are moved upward to return to the initial position, and the apparatus waits until the next carrying-out operation.

Note that the timing of supplying the cart b onto the cart mounting base 7 is not limited to just before the opening/closing mechanism 13 is moved to expand and open.
It may be provided in advance on the trolley mounting base 7 and left on standby.
