is provided. The conveyance cart pull-out device 6 is mounted on the rotary table 13 of the traverser 3 at position B (the direction is reversed by 180 degrees compared to when it is at position A, as described later) connected to this return conveyance path 2. It pulls out the carriage 4 to a position where it can engage with the conveyor 44, and as shown in FIG. An endless chain 49 for driving a rod is fixed nearby and driven in any forward or reverse direction by a motor 48, and the end of the rod 47 is rotatably supported only rearward and downward, and is held in an upright state by a spring 50. and a pusher 51.

The slat conveyor 30 of the forward conveyance path 1 has slat plates 52 located at appropriate intervals, as shown in FIGS. The movable slat plate 52 is pivoted to the movable slat plate 52 and is biased and held at the upper limit position limited by a stopper 56 by a pair of left and right coil springs 55.
The front free wheels 26 of the transport vehicle placed on the fixed slat plate 57 adjacent to the front of the movable slat plate 52 are configured to be backed by the free end portion 58 of the movable slat plate 52 facing diagonally forward and upward. .
When the transport vehicle 4 collides with the preceding stopped transport vehicle, the movable slat plate 52 rotates downward against the spring 55 so as to slip under the wheels 26, allowing the vehicle to pass under the stopped transport vehicle. It's summery. In the figure, 59 is a load supporting wheel mounted on both left and right sides of the fixed slat plate 57, and 60 is the same wheel 59.
The fixed rails 61 are wheel guides that position the wheels 26 and 27 of the transport vehicle 4 on the slat conveyor 30.

Next, the method of use and operation will be explained. In the forward conveyance path 1, as shown in FIG. ,2
7 is placed on the slat conveyor 30, and is transported by driving the slat conveyor 30 and backing the front free wheel 26 with the movable slat plate 52, as shown in FIG. It is stopped at the end of the forward conveyance path 1 by the stopper 32 shown. The slat conveyor 30 is continuously operated and the following conveyor 4 is transferred in the same way, but as mentioned earlier, if it collides with the preceding stopped conveyor 4, the following conveyor will automatically stop and the slats will be transferred. Wheels 26, 27 of conveyor cart 4 stopped on conveyor 30
rotates on its own axis, and the movable slat plate 52 passes under these wheels 26, 27 while tilting forward. With the traverser 3 in position A as shown in FIG.
7 forward rotation. As a result, the driven member 28 of the carrier 4 is pushed back by the pusher 39, and the carrier 4 is moved to the rotating base 1 of the traverser 3.
3. Pushed upwards. At this time, the wheels 26 and 27 on one side of the carriage 4 transfer from the grooved rail 31 to the grooved rail 41 on the rotary table 13, and are guided by this to move straight. Further, the wheels 34 on the front end side of the rod 35 are transferred from the guide rail 33 to the guide rail 40 on the rotary table 13, and are guided by this.

After transporting the carriage 4 to a predetermined position on the rotary table 13, the endless chain 37 is reversed and the rod 35 is moved back to return to its original position. The stopper 32 protrudes immediately after the carriage passes, and stops the following carriage 4 being sent by the slat conveyor 30. The pusher 39, which moves backward with respect to the driven member 28 of the following conveyance vehicle, passes while rotating against the force of the spring 38.

When the loading of the carriage 4 onto the rotary table 13 is completed, the endless chain 16 is rotated forward by the motor 17, and the lateral movement carriage 11 is guided by the rails 7 and 8 and moved laterally toward the B position. In the process of this lateral movement, the rotating wheel body 23 meshes with the rack gear 24 as shown in FIG. 4, and the rotating wheel body 23 is rotated by the rack gear 24 as the lateral movement truck 11 moves laterally. This rotation causes gear 22 and chain 2
1, the rotating table 1 via the gear wheel 20 and the vertical shaft 12
3, and the rotary table 3 rotates as the transverse carriage 11 moves. From the rack gear 24 to the rotating wheel body 2
The rotation angle of the turntable 13 until 3 leaves is exactly 180
If the structure is configured so that the traverser 3 reaches the B position, the conveyance cart 4 and the rotary table 13 will have been reversed 180 degrees front and back.

When the traverser 3 reaches the B position, the carrier pull-out device 6 shown in FIG. 1 is operated. That is,
As shown in FIG. 5, the endless chain 49 is rotated in the forward direction to advance the rod 47 toward the traverser 3 until the pusher 51 passes the driven member 28 of the transport vehicle 4 while pushing it backward against the spring 50. Move the rod 47. Next Endless Chain 4
9 is reversed to move the rod 47 backward, the pusher 51 hooks the driven member 28, and the carriage 4 is pulled out from the rotary table 13 onto the backward conveyance path 2. At this time, the wheels 26 and 27 of the transport vehicle 4 are transferred onto the grooved rails 42 and 43, and are guided to move straight while being pulled out to a position where they can engage with the conveyor 44 for propelling the vehicle. After this, the carriage 4 is moved to the grooved rail 4.
2, 43 and is conveyed by a conveyor 44.

Traverser 3 after sending out the transport vehicle 4
is returned to the A position by reversing the endless chain 16, but at this time, the rotary ring 23 engages with the rack gear 24 and the rotation is reversed, so the rotary table 13 rotates 180 degrees in the opposite direction, and when it reaches the A position, , and connects to the forward conveyance path 1 in a state where it returns to its original orientation.

In addition, at the A position and the B position, the lateral movement truck 11
and a rotating table fixing means that locks the rotating table 13 so that it cannot rotate when the rotating wheel body 23 is separated from the rack gear 24.
Alternatively, carrier fixing means for positioning the carrier 4 loaded at a predetermined position on the rotary table 13 may be provided as necessary.

According to the traverser of the present invention, which can be implemented as described above, when a transport vehicle traverses from the end of one transport route to the start end of another transport route, the orientation of the transport transport vehicle is automatically changed by 180 degrees. Since it can be reversed, for example, even on the backward conveyance path as in the embodiment, the front and back direction can be made to be the positive direction with respect to the conveyance direction in the same way as when conveying on the outbound conveyance path. This is convenient for various operations on transported objects, and is also convenient when the transport vehicle is propelled by another conveyor or the like. Furthermore, since no special power source or control means is required for the rotation of the rotary table, it is economical and easy to implement.
