Next, the operation of the present invention will be explained.

When a start switch (not shown) is turned on, each actuator starts operating, and the cargo 1 carried into the carrying section 10 is
It reaches the loading device 26 via the depalletizer 16 and the feed conveyor 20.

The cargo 1 conveyed to the inclined conveyor 28 of the loading device 26 is transferred onto the loading device 30 by the direction changing device 40, which is normally in the raised position by extension of the air cylinder 41.

That is, the elevating plate 4 constituting the direction changing device 40
9 is raised, the rear end thereof is continuous with the front end of the inclined conveyor 28, and the conveying surface by the roller 48, which is rotatably pivotally connected to the elevating plate 49, rises beyond the conveying surface of the traverse conveyor 29, and It will slope downward. Therefore, the load l is transferred from the inclined conveyor 28 onto the stowage device 30 by its own weight.

On the other hand, at the same time, the stopper body 53 of the lift stopper 52 is also raised by the expansion of the air cylinder 54, and the cargo 1 conveyed by the direction changing device 40 comes into contact with this stopper body 53 and is stopped.

Then, the loading of the cargo 1 onto the loading device 30 is detected by the optical switch LS2, and the air cylinders 54 and 41 are contracted in response to this detection signal.

As a result, the conveyance surface formed by the rollers 48 of the direction changing device 40 is located below the conveyance surface of the cross conveyor 29, so that the cargo 1 is placed on the cross conveyor rollers 29a of the cross conveyor 29. At the same time, it is conveyed to the side in the direction of the lateral force (to the right in the embodiment) (see FIG. 9).

A timer (not shown) is activated in accordance with the transport time for the cargo 1 to leave the group of direction change devices 40, and the air cylinders 41 and 54 are extended again, and the stopper body 53 of the lift stopper 52 and the lift plate 49 of the direction change device 40 are activated.
is raised to prepare for the next cargo 1 to be carried in.

In this way, the loads 1 conveyed onto the stowage device 30 are individually transferred laterally along their front edges, and when they are lined up horizontally on the stowage device 30 (see Figs. 10 and 11).
(see figure), the air cylinder 70 operates to contract.

When the air cylinder 70 contracts, the torque shaft 68 is rotated in the clockwise direction in FIG. 29 and is raised above the conveyance surface of No. 29.

When the lifting of the bushing main body 66 is completed, the bushing 58 and the loading fork 57 move forward.

That is, when electric motors M1 and M2 are driven in normal rotation,
The rotational force rotates the pinions 62, 62a through the chain sprocket 61° 61a, and the pinions 62, 62a rotate.
2, 62a is moved forward along the guide 63, the load 1 is pushed forward by the pusher body 66.

At this time, since the loading fork body 65 moves forward at the same time, when the center of gravity of the load 1 exceeds the front end of the loading device 30, the load 1 is transferred and placed on the loading fork body 65, and the loader body 65 moves forward. In conjunction with the extrusion by 66, the loading device 3
It stops at a position beyond the front end of 0 (see Fig. 12).

In this state, the cargo 1 is placed on the loading fork body 65, and at the same time, its back surface is in contact with the front surface of the pusher body 66, which is located beyond the front end of the loading device 30.

When the cargo 1 is loaded in this way, the electric motor M2 is then driven in the reverse direction, and contrary to the above, the rack 6 is loaded.
4a is retracted, and the loading fork main body 65 is retracted.

Therefore, the loading fork main body 65 supporting the lower surface of the cargo 1 is moved backward while the rear surface of the cargo 1 is blocked by the pusher main body 66. As a result, the cargo 1 falls onto the floor surface of the cargo box 2 or onto the cargo l that was previously stowed. Descended and stowed (13th
(see figure).

After that, the electric motor Ml is driven in reverse, and the air cylinder 7
0 is extended, the bushing main body 66 is moved back to the normal position via the rack 64, and at the same time descends along the guide 67, so that its upper end is located below the conveying surface of the traverse conveyor 29.

Next, the stowage device 30 is raised by a predetermined amount by a lift device (not shown) in order to stack the next baggage 1 on top of the previously stowed baggage 1, and prepares for the stowing operation of the next baggage 1.

In addition, if the lifting position of the loading device 30 is not appropriate,
As the loading fork body 65 moves forward, there is a risk that the tip of the loading fork body 65 will collide with the cargo 1 that has been loaded first, but in that case, the sensor LS3 will detect the moment immediately after the collision, and the electric motor It is designed to stop the rolling and prevent damage to the cargo 1.

(Effects) As described above, according to the great invention, it is possible to continuously line up the cargo conveyed via the inclined conveyor on the stacking device via the direction change device and the traverse conveyor, There is almost no loss time and it is possible to carry out efficient loading work.
