By setting the position of the destination indicator 36 by the destination setting device 11, the transport vehicle 12 can move from the storage line 6 to each station 3A to 3D, between each station 3A to 3D, or between each station 3A to 3D. station 3
It is carried out from A to 3D to storage line 6,
Then, the set position of the destination indicator 36 is canceled by the destination canceling device 10 at each station 3A to 3D.

Next, an example of the destination release device 10 will be explained based on FIGS. 4 to 6. A bracket 40 is erected on the side opposite to the destination indicator 36 attached to the self-propelled transport vehicle 12 at the appropriate side of the fixed line, and the front side of this bracket 40 is in contact with the side surface of the machine frame 13. A freely rotating roller 41 is provided.
At the level of the destination indicator 36, a swingable locking pawl 43 is attached via a vertical pin 42. This locking pawl 43 has a locking portion 4 at its front end.

When the destination release device 10 provided at the entrance of each of the stations 3A to 3D is in the open state without the transport vehicle 12, the locking pawl 43 is moved by the force of the spring 44 until it comes into contact with the stopper 45. The locking portion 43a thereof is oscillated, and its locking portion 43a is projected into the movement trajectory of the destination indicator 36. In this state, the transport vehicle 1 runs into each station 3A to 3D.
2, the outer surface of the machine frame 13 is guided by the idling rollers 41, so that unexpected rolling is restricted. In order to enter each of the stations 3A to 3D, the destination indicator 36 pointing to the corresponding display [3 to 6] is caught on the locking portion 43a, and the transport vehicle 12 runs while remaining at this locking position. do. This brings the destination indicator 36 to the display [7] side corresponding to the storage line 6 with respect to the transport vehicle 12. The destination indicator 36 left at the locking position comes into contact with the stopper 45, and finally becomes integrated with the transport vehicle 12. As a result, the locking pawl 43 swings against the spring 44 due to the running force of the transport vehicle 12, and the locking pawl 43 disengages from the destination indicator 36. At this time, the destination indicator 36 points to the display [7] corresponding to the storage line 6. Therefore, when the transport vehicle 12 is stopped at the stations 3A to 3D and continues to run after completing the intended cargo handling work, the transport vehicle 12 enters the storage line 6. Furthermore, by activating the destination setting device 11 when exiting from the stations 3A to 3D, the user enters the corresponding station 3A to 3D.

Next, an example of the destination setting device 11 is shown in FIGS.
This will be explained based on the diagram. A fixed frame body 46 is provided on the side opposite to the destination indicator 36 attached to the self-propelled conveyance vehicle 12 at the proper side of the fixed line, and the fixed frame body 46 is provided with a fixed frame body 46 along the conveyance direction 16 and from the left and right sides. A pair of guide rods 47 are attached. A lower movable base 48 and an upper movable base 49 are provided which can be reciprocated while being guided by the guide rod 47. Both movable bases 48 and 49 are brought into contact with each other via a washer 51 by the elastic force of a compression spring 50, so that they basically reciprocate as one unit. A reciprocating drive device 52 for both the movable tables 48 and 49
is a rack 53 attached to the lower surface of the lower movable base 48.
, a motor 54 which is attached to a fixed frame 46 and can be driven in forward and reverse directions, and a pinion 56 which is attached to a motor shaft 55 and always engages with the rack 53. In order to regulate the amount of reciprocating movement of the lower movable base 48, cam plates 57 and 58 are attached to the front and rear ends of the lower movable base 48, respectively.

That is, this positioning device 70 includes a locking body 72 that can be engaged with and detached from the fixed magnet 35 by swinging around a vertical pin 71, and this locking body 72.
It is composed of a solenoid 73 that swings the solenoid 73.

Transport vehicle 12 has reached stations 3A to 3D
The intended cargo handling work is performed on the transport case 24. Then, a destination is set in order to cause the transport vehicle 12 to travel to the next station 3A to 3D. That is, the transport vehicle 12 is stopped at the side of the destination setting device 11. At this time, the fixed magnet 35 is in contact with or approaching the locking body 72 in the protruding position. Also, the destination indicator 36
All the setting pins 65A to 65F are located in the retracted position on the lower side. In this state, the setting pin 65A corresponding to the desired station 3A to 3D
~65F is projected. This activates the corresponding solenoids 66A-66F and springs 69A-69.
This is to make one setting pin 65A to 65F protrude against F. Next, the motor 54 is activated to move both movable platforms 48 and 49 in the transport direction 16. Then, the protruding setting pins 65A to 65
F comes into contact with the destination indicator 36, and then moves the destination indicator 36 backwards. the movable table 48,
Although the movement stroke S of 49 is constant, which setting pins 65A to 65F are relative to the destination indicator 36?
Since the engagement differs, the pushing stroke amount of the destination indicator 36 with respect to the transport vehicle 12 differs, and thus the destination is set. Since the fixed magnet 35 is received by the locking body 72 during this setting operation, the stroke reference is determined and accurate destination setting is performed. After setting the destination, the transport vehicle 12 is enabled to travel by swinging the locking body 72 in and out using the solenoid 73, and when traveling, the setting pins 65A to 6
Since the destination indicator 36 moves away from the 5F, the set position will not be disturbed. Movable stand 48,4
9 is returned to the upper side, and by protruding the locking body 72, it becomes ready to wait for the next conveyance carriage 12.

The rail device 27 is disposed inside the duct 74, and the transport vehicle 12 is connected to the duct 74 upward from the support 25.
Drive with it protruding outward.

In the above embodiment, the destination setting device 11 is of a type in which a plurality of setting pins 65A to 65F are arranged on an upper movable base 49 that moves at a constant stroke S, but in this case, a single setting pin is attached. Alternatively, the stroke of the movable base may be changed.

As described above, according to the present invention, it is possible to automatically and easily cancel and slide the destination indicator provided on one side of the transport vehicle so that it can be slid in the transport direction, and furthermore, the destination indicator can be automatically and easily set. The direction of setting is from the direction in which the setting pin follows and backs up the destination indicator.
It can be done reliably and easily, and
It is possible to prevent the set position from being disturbed when re-travelling after setting. The present invention as described above can be advantageously employed particularly in a transportation mode in which most of the material is contained in a duct or the like (see FIG. 3).
