By setting the position of the destination indicator 36 by the destination setting device 11, the transport vehicle 12 can travel 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 of the present invention will be explained based on FIGS. 4 to 6. A pair of upper and lower horizontal plate-shaped fixing plates 40 and 41 are provided on the side facing the destination indicator 36 attached to the self-propelled transport vehicle 12 at a proper side of the fixed line. On the lower surface side of the lower fixing plate 41, there is a conveyance direction 16.
A pair of chain rings 42 and 43 are connected to vertical axes 44 and 45 in
These chain rings 4
A passive chain 46, which is an example of a passive rotating body, is wound between 2 and 43. This passive chain 46 rotates integrally in response to the traveling force of the self-propelled transport vehicle 12, and for this purpose, the passive chain 47A, which can be engaged with and backed by the fixed magnet 35,
47B and 47C are 3 at equal intervals in the chain length direction.
They are arranged side by side outward from the point. The upper vertical shaft 44 of the vertical shafts 44, 45 passes through the lower fixing plate 41, and a large diameter chain ring 48 is attached to its protruding end. A vertical axis 49 passing through the upper fixing plate 40 further below the vertical axis 45 on the lower side
is rotatably attached, and a small diameter chain ring 50 is attached to the lower end of this vertical shaft 49. And large diameter chain ring 4
8 and the small-diameter chain ring 50, an interlocking chain 51, which is a speed-increasing interlocking rotating body, is wound. The vertical axis 4
A chain ring 52 is attached to the upper end of the upper fixing plate 9, and a chain ring 54 is attached to the upper surface side of the upper fixing plate 40 at the uppermost position via a vertical shaft 53 so as to be freely rotatable. A drive chain 55, which is an example of a drive rotating body, is wound between these chain rings 52 and 54. This drive chain 55 is located at the same level as the destination indicator 36, and boosters 56A and 56B are provided laterally outward from two locations equidistantly spaced in the lengthwise direction of the chain.
Therefore, the pusher tools 56A, 56B are configured to be able to come into contact with the destination indicator 36 from the rear. 5
Reference numeral 7 denotes a stopper device for determining the starting point of the destination release device 10, which consists of a solenoid 58 and a stopper rod 59 that moves up and down with the solenoid 58.
This stopper lever 59 moves in and out of the moving path of the backing tools 56A and 56B. 60 is a tension chain ring, 61 is a guide body of the passive chain 46, 62
indicates a guide body of the drive chain 55.

The solid lines in FIGS. 4 and 6 indicate when the transport vehicle 12 enters the destination release device 10. At this time, the stopper lever 59, which is in the stopped state in FIG. 6, is lowered to release the receiving pusher 56A. As the transport vehicle 12 travels, the fixed magnet 35 first comes into contact with the passive tool 47A located at the position A. At this time, in the figure, the destination indicator 36 is located above the fixed magnet 35, but this is located somewhere within the range A depending on the setting position. As the transport vehicle 12 further travels, the fixed magnet 35
pushes the passive gear 47A, and the passive chain 4
6 are rotated integrally. The rotational force of this passive chain 46 is generated by the chain ring 42, the vertical shaft 44, the large diameter chain ring 48,
It is transmitted to the chain ring 52 via the interlocking chain 51, the small diameter chain ring 50, and the vertical shaft 49, thereby rotating the drive chain 55 in the same direction. At this time, due to the transmission structure from the large diameter chain ring 48 to the small diameter chain ring 50, the drive chain 5
5 rotates at a higher speed than the passive chain 46. As a result, the support tool 56 moves at high speed from the position D.
A catches up with the destination indicator 36 and abuts it from behind, and backs up the destination indicator 36 to move it in the transport direction (traveling direction) 16 with respect to the traveling transport carriage 12. Therefore, the passive device 47A
When it reaches the position B and is removed from the fixed magnet 35, the pusher 56A reaches the position E and moves the destination indicator 36 to the reset position. At this time, the pusher 56A, which was in the position E, reaches the position D and is received by the stopper rod 59, and the passive tool 47C, which was in the position C, reaches the position A and waits for the next carriage 12. It turns out.

As described above, according to the present invention, the destination indicator set on one side of the carrier can be automatically canceled by using the running force of the carrier, and furthermore, the direction of the cancellation can be determined by the direction of travel. Since the process is carried out from the direction of following the conveyance vehicle, the process can be carried out reliably and easily. Furthermore, the running force can be transmitted from the carrier using the main body of the carrier or necessary parts attached to the main body, without complicating the structure.
