The track 2 is formed with two concave guide grooves 14 parallel to the base surface 13, and these guide grooves 14 are made of a copper plate or the like and are slightly larger than the diameter of the traveling guide 6. A U-shaped groove plate 15 having a width and a height slightly larger than the thickness is mounted. As shown in FIG. 9, the track 2 has a U track 1 having a track interval U formed so as to correspond to a case where the travel guide 6 is located outside the travel wheels 5 and the interval between the travel guides 6 is wide.
6 and a U 'track 17 having a track interval U' formed so as to correspond to a case where the travel guide 6 is located inside the travel wheel 5 and the interval between the travel guides 6 is narrow as shown in FIG. doing.

The track 2 is a straight track 1 shown in FIG.
8, a curved track 19 shown in FIG. 6, a branch shown in FIG. 7, a merging track 20 and an orthogonal track 21 shown in FIG.

The orthogonal track 21 is formed so that the U track 16 and the U 'track 17 are orthogonal to each other.
When the traveling guide 6 comes to the position shown in FIG. 8, the traveling wheel turns 90 degrees clockwise when the carrier 1 tries to travel in the direction of the arrow E, and the traveling guide 6 moves rightward in the guide groove 14. , The vehicle 1 can change its direction at a right angle. On the outer or inner base surface 13 of the track 2, a road plate 22 made of a steel plate or the like for running the running wheels 5 smoothly is formed in parallel with the track 2 at intervals V or V '. Have been.

As shown in FIGS. 3 and 4, the inclined track 3 has a concave guide groove 24 formed parallel to the track 2 with respect to a vertical surface 23 on one side of the track 2. The guide groove 24 is provided with a U-shaped groove plate 25 formed of a steel plate or the like and having a width slightly larger than the diameter of the tilt guide 8 and a depth slightly larger than the thickness. ing. And
As shown in FIG.
6 and a tilting track portion 27 are provided, and by switching a switching member 29 of a tilting point 28, a tilting guide 8 is provided.
Can travel on the horizontal track section 26 or the tilt track section 27. The switching member 29 is operated by an air cylinder (not shown).

FIG. 12 shows an example in which the transport device of the present invention is used for sorting loads. For example, loads 31 placed on an induction conveyor 30 move to the downstream side and move to a transport vehicle standby section 32. The required number of stocked vehicles (one vehicle in this case) starts running and stops before the induction conveyor 30. And luggage 31
The sorting destination is read by the coding device 33, and the sorting destination is stored in the ID card (not shown) provided in the carrier 1 by keying the sorting destination by the coding device 33. And this luggage 31 is the transport vehicle 1
And transported downstream. And the sorting destination is Q
Then, the optical sensor 34 reads the sorting destination Q, and in the upstream chute conveyor 35, the switching member 29 of the tilting track 3 is at the solid line position shown in FIG. 26, and the carrier 31 travels without tilting. Then, when the sorting destination approaches the upstream side of the chute conveyor 36 of Q, the optical sensor 37
Reads the sorting destination and switches the switching member 29 of the tilting orbit 3.
11 slides to the position indicated by the two-dot chain line shown in FIG. 11 and the tilting guide 8 of the transport vehicle 1 enters the tilting track portion 27, so that the loading platform 7 is tilted and the load 31 on the loading platform 7 is placed on the chute conveyor 36. And sorted into Q of the sorting destination. Then, the empty transport vehicle 1 is forwarded to the transport vehicle standby section 32 and stocked. Reference numeral 38 denotes a primary side of the linear motor, and a secondary side (not shown) is attached to the carrier 1 so that the carrier 1 is driven by using the linear motor as a drive source.

Since the transport device of the present invention is configured as described above, the traveling guide 6 of the transport vehicle 1 is fitted on the track 2, and the tilt guide 8 is fitted on the tilt track 3 while the traveling wheels 5 are fitted.
Travels on the road board 22. Since the vehicle travels on the track 2 having a straight line, a curve, a branch / merge, and an orthogonal direction and having a very small radius of curvature, the direction can be changed quickly and directly. In addition, since the loading platform 7 is guided by the tilt track 3 including the horizontal track section 26 or the tilt track section 27, the carrier 7 travels.
The traveling of the transport vehicle 1 and the tilting of the carrier 7 can be freely performed. In the present embodiment, the running means of the transport vehicle is a linear motor, but may be pushed by a normal motor or an operator, and is not limited to these.

[0018]

As described above, the transport device according to the present invention is provided with a plurality of turning wheels provided on a bogie frame of a carrier and point symmetry with respect to the center of the plane in the horizontal plane of the bogie frame. Since the vehicle has a plurality of traveling guides provided at the positions and a track into which the traveling guides are fitted and which can change the direction of the vehicle at an orthogonal position, the vehicle can travel freely even in a narrow space. Dead space in the orbit can be greatly reduced. Moreover, a loading platform provided on the upper part of the bogie frame and capable of tilting in a direction perpendicular to the traveling direction, a tilting guide provided on a side portion of the loading platform, and the loading guide in which the tilting guide is fitted is set at a predetermined position. Since it has a tilting track provided with a part that descends to tilt, the necessary transport vehicle is tilted at a predetermined position and the load on the carrier of the transport vehicle is transferred to the downstream side Can be
There are excellent effects such as the ability to sort luggage with a simple device.
