[0002]

2. Description of the Related Art In recent years, there is a tendency to introduce an automatic guided vehicle for transporting luggage, thereby saving labor. Loading and unloading of the automatic guided vehicle is performed as follows.

That is, as shown in FIG. 15, a push rod b and a handling roller c are provided on a carrier of an automatic guided vehicle a, and a handling roller c is provided at a loading / unloading station d. e is carried in and out.

[0006] Alternatively, as shown in FIG. 16, a roller conveyor f is attached to the loading platform of the automatic guided vehicle a and the loading / unloading station d.
May be provided to carry in / out the luggage e.

[0005]

However, in any case, a transfer device for the load e must be provided on both the automatic guided vehicle a and the loading table d, which complicates the mechanism and the manufacturing cost. However, there was a problem that the bulk increased.

The present invention is intended to solve such a problem, and an object of the present invention is to provide a transfer device having a simple mechanism.

1 shows a part of the transfer device of the present invention. The automatic guided vehicle 1 runs along a magnetic tape 3 installed on a floor 2. The automatic guided vehicle 1 has a height from the floor 2 has a bed 4 of an H _1, the upper rear surface of該荷table 4, the height from the floor 2 by projecting a stopper 5 of an H ₁ (See FIG. 4). In addition, automatic guided vehicle 1
Has a U-shaped front stopper 6 at the front of the vehicle body. Both ends of the stopper 6 are fixed to a roll bar 7, and the roll bar 7 has an arm 8 in the center. Then, the arm 8 is moved to the front 1 of the vehicle body of the automatic guided vehicle 1.
The front end of the roll bar 7 is rotatably supported by the vehicle body, and both ends of the roll bar 7 are projected from the automatic guided vehicle 1 in the vehicle body width direction. The arm 8 is inserted into the hole 9 through a support member 10 as shown in FIG.
The springs 11A and 11B urge the actuator vertically. Then, the lower end locking portion 10a of the support member 10 is always engaged with the step 9a of the hole 9 to hold the arm 8 horizontally. In addition, as shown in FIG. 3, the provision of the step 9 a in the hole 9 may be stopped, and the support member 10 may be engaged with the upper edge of the hole 9.

A loading / unloading station 12 is arranged in the passage of the automatic guided vehicle 1. The station 12 includes a pair of luggage placing members 13, 13 which are arranged opposite to each other so as to sandwich the path of the automatic guided vehicle 1.
And the horizontal plane 13a of the H ₂ is the height from the floor 2, horizontal surface 1
The height from the floor 2 to 3a toward the reverse direction of the automatic guided vehicle 1 is formed with a falling slope surface 13b to the position of H _3. Further, guide bars 14, 14 are respectively arranged on the sides of the luggage placing members 13, 13 in parallel with the members 13, and these guide bars 14
And an inclined portion 14b formed by bending the end thereof upward.
And The height of each of the above components is H ₁
> H ₂ > H ₀ > H ₃ . Also, the roll bar 7, the upper end of the front stopper 6, the horizontal portion 14 a of the guide bar 14, the inclined portion 14 of the guide bar 14
The heights to the rear end of b are H ₄ , H ₅ , H ₆ , and H _{7, respectively.}
When they are set to the relationship _{H 5> H 2, H 7} > H 4> H 6.

When the automatic guided vehicle 1 is advanced from the position shown in FIG. 4 toward the loading / unloading station 12, the roll bar 7 comes into contact with the inclined portion 14b of the guide bar 14 as shown in FIG. It is pushed down clockwise (in the direction of the arrow in the figure) against the urging force of the spring 11A. That is, as the automatic guided vehicle 1 advances, the front stopper 6 falls forward, and the upper end thereof eventually reaches below the horizontal plane 13a of the luggage placing member 13. Therefore, the automatic guided vehicle 1 passes below the load W placed on the load placing member 13 (see FIG. 6). Then, when the automatic guided vehicle 1 reaches the position shown in FIG. 7, the roll bar 7 comes off the front end of the guide bar 14 and moves back to the original position, and the front stopper 6 is moved beyond the horizontal plane 13 a of the luggage placing member 13. It will protrude upward. As described above, the front stopper 6 is provided in the luggage placing area (the horizontal plane 13) of the luggage placing member 13.
The portion is moved down by a guide bar 14 as a control means just before reaching a portion (excluding the front end portion of a), and when it passes through that area, the descending state is released. When the automatic guided vehicle 1 is moved backward from this position, the front stopper 6 pushes the load W backward, and the automatic guided vehicle 1
(See FIG. 8). At this time, the front stopper 6 tries to fall forward by receiving the reaction force from the load W, but the rotation of the roll bar 7 is
4, the stopper 6 does not tilt greatly. When the automatic guided vehicle 1 is further moved backward, the roll bar 7 comes into contact with the inclined portion 14b of the guide bar 14 as shown in FIG.
The roll bar 7 rotates in the counterclockwise direction (the direction of the arrow in the figure) while contracting the roll bar 1B.
4b can be overcome.

Since the present embodiment is configured as described above,
Loading to the automatic guided vehicle 1 may be performed in the following manner. First, the load W is placed on the load placing area on the horizontal surface 13 a so as to straddle the load placing members 13, 13, and then the automatic guided vehicle 1 is advanced toward the loading / unloading station 12. Then, the automatic guided vehicle 1 is caused to pass below the load W as described above, and when it reaches a position (the position in FIG. 7) where the lowered state of the front stopper 6 is released, the automatic guided vehicle 1 is moved backward. 4 to 9 show the above process.

On the other hand, the unmanned transport vehicle 1 carrying this loading
Is moved into another loading / unloading station 12, the load W is pushed by the rear stopper 5 as shown in FIG. 10 and rides on the inclined surface 13 b of the load placing member 13. Then, when the load W is pushed up to the horizontal surface 13a beyond the inclined surface 13b as shown in FIG. 11, the automatic guided vehicle 1 is moved backward. Then, the automatic guided vehicle 1 passes below the luggage W while the front stopper 6 is in the lowered state, and the unloading to the loading / unloading station 12 is completed.

In this embodiment, the arm 8 can be turned up and down from the horizontal state. However, as shown in FIG. 12, the arm 8 can be turned only down. In that case, the guide bar 14 has its inclined portion 14b
It is necessary to be able to rotate with respect to a. FIG.
3 and 14 show an example of such a structure. Horizontal portion 20a of the guide bar 20 as well as a double structure with an inner member 20a ₁ and the outer member 20a _2, combines the inner member 20a ₁ on the inclined portion 20b, further springs between the inner member 20a ₁ and the frame 21 22 is installed. Incidentally, the axis C ₁ of the inclined portion 20b are is slightly inclined relative to the axis C ₂ of the horizontal portion 20a as shown in FIG. 14.

[0014]

According to the present invention, since there is no need for an automatic guided vehicle and a load transfer device conventionally provided in the loading / unloading station, the mechanism can be simplified and the manufacturing cost can be reduced. . Further, the automatic guided vehicle according to the present invention is a very simple one in which the roll stopper is brought into contact with the guide of the loading / unloading station, and the front stopper is moved up and down by pushing the roll bar up and down.
No special drive mechanism is required for this vertical movement. For this reason, the manufacturing cost is low, the power cost is not required, and the equipment failure is reduced. In addition, the front stopper can be automatically moved up and down without an operator's operation. Furthermore, the loading / unloading station of the present invention
Luggage placing member having an inclined surface whose end is inclined obliquely downward
And a guide having a sloping portion whose tip is inclined obliquely upward.
It has. Therefore, one loading / unloading station
To transfer the goods to the loading / unloading station,
It is possible to transfer the luggage placed on the
Cost is low. In addition, at the loading / unloading station
The length can also be shortened according to the size of the luggage
Therefore, it can be installed even in a narrow space.
