BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transportation facility using a self-propelled carriage that can travel on a fixed route in a factory, for example.

[0002]

2. Description of the Related Art Conventionally, there is, for example, one shown in FIG. That is, the conveyance path 52 is formed by the pair of first linear path portions 50 facing each other and the second linear path portion 51 that passes between one ends of the first linear path portions 50. Self-propelled carriage 53 on both first linear path portions 50
Linear traveling rails 54a, 54b for supporting and guiding the vehicle are laid, and a linear delivery rail 56 for supporting and guiding the delivery moving body 55 is laid on the second linear path portion 51.
Each of the traveling rails 54a, 54b is provided on the delivery moving body 55.
A linear split rail 57 that can be freely connected is provided at one end of the.

A conveyor for transportation is provided around the transportation path 52.
A 58 and an automated warehouse 59 are installed so as to face the traveling rails 54a and 54b. The automatic warehouse 59 is composed of a pair of shelves 61 arranged side by side with a passage 60, and a loading / unloading device 63 that can travel horizontally and vertically on a fixed path 62 in the passage 60.

According to this, each self-propelled carriage 53 travels on the first straight path portion 50 while being supported and guided by the traveling rails 54a and 54b. In addition, the self-propelled carriage 53 is connected to one of the traveling rails 54a.
After moving from one end to the split rail 57, the delivery moving body 55 is moved toward the other traveling rail 54b. As a result, the moving object for delivery is
55 split rail 57 is connected to the other traveling rail 54b,

Was being transported from the transport conveyor 58 to the transport conveyor 58.

[0005]

However, in the above-mentioned conventional example, the delivery moving body 55 has the second linear path portion 51.
Since the vehicle travels on the delivery rail 56 that is laid linearly, the vehicle travels right beside (orthogonal direction) with respect to the first linear path portion 50. Therefore, when the delivery moving body 55 moves on the second linear path portion 51, the other end surface of the split rail 57 comes into sliding contact with one end surface of the traveling rail 54a (or 54b), so that the traveling rails 54a, 54b. External force in the moving direction is applied to one end of the rails and the other end of the split rail 57 to be damaged, one end of the traveling rails 54a and 54b and the other end of the split rail 57 are worn, and abnormal noise or vibration is caused by sliding contact. There was a problem that it occurred.

In order to solve the above problem, as shown in FIG. 5, one end of the traveling rails 54a and 54b and the split rail 57 are provided.
It was necessary to provide a gap S at the joint with the other end. However, when the gap S is provided, there arises a problem that vibration occurs when the self-propelled carriage 53 passes over the gap S.

In general, most of the self-propelled carriages 53 are electrically driven, so that a power supply rail (not shown) was installed along the traveling rails 54a, 54b and the split rail 57. According to this, it is necessary to provide a gap at the joint between the power feeding rails on the traveling rails 54a and 54b side and the power feeding rail on the split rail 57 side as in the above, and therefore, the assembly provided on the self-propelled carriage 53 is required. When electrons (not shown) passed through this gap, the current collector came off from the power supply rail.

The present invention solves the above problems, and an object of the present invention is to provide a transfer facility using a self-propelled carriage that does not require a gap between the traveling rail and the split rail.

[0009]

In order to solve the above-mentioned problems, a transport facility using a self-propelled carriage according to the present invention is provided with a pair of straight line path portions facing each other and passing between one ends of these straight line path portions. A conveyance route is formed from the arcuate path that bulges outward, and linear travel rails that support and guide the self-propelled carriage are laid on both linear path parts. An arcuate delivery rail for supporting and guiding the body is laid, and a linear dividing rail connectable to one end of the traveling rail is provided on the delivery moving body.

[0010]

According to the above construction, the delivery moving body is supported and guided by the delivery rail having an arcuate shape and moves along the arcuate path portion. As a result, the other end of the split rail of the transfer vehicle moves laterally while displacing from one side to the other side of the one end of the traveling rail, not right side (orthogonal direction),
It is contacted and connected to one end of the traveling rail. Therefore, the other end of the split rail does not come into sliding contact with one end of the travel rail, and a gap between the other end of the split rail and one end of the travel rail can be eliminated.

When the split rail is separated from the traveling rail, the other end of the split rail is displaced laterally from one end of the traveling rail to the other from one side instead of being right side (orthogonal direction). It moves and separates from one end of the rail for traveling. Therefore, the other end of the split rail does not come into sliding contact with one end of the travel rail, and a gap between the other end of the split rail and one end of the travel rail can be eliminated.

Each of the shelves 33 of the automatic warehouse 16 and one end of the transfer conveyor 15 face the linear path portion 1, and the self-propelled carriage 4 is transferred to the transfer conveyor 15 and the loading / unloading device 35 of the automatic warehouse 16. It is formed so that objects can be handed over.

The operation of the above structure will be described below.
Each of the self-propelled carriages 4 travels through a traveling wheel 17 and travels through a rail 5 for traveling.
The vehicle travels on the linear path portion 1 while being supported and guided by a and 5b and the take-out split rail 13. In addition, the self-propelled carriage 4 is transferred from one end of one traveling rail 5a to the delivery moving body 6a.
After moving onto the divided rail 14 of No. 1, by driving the electric motor 28, as shown from the phantom line in FIG. 2 to the solid line,
The arm 22 rotates to the other traveling rail 5b side via the intermediate gear 27 and the gear 26. Along with this rotation, the cam roller 29 freely rotates and moves in the length direction along the guide groove 30 and pushes the transfer moving body 6a toward the arcuate path portion 2 direction. It is supported and guided by 7a and moves on the arcuate path portion 2 toward the other traveling rail 5b. As a result, the other end of the split rail 14 of the transfer moving body 6a moves away from one end of one traveling rail 5a, and the other traveling rail 5 moves.
It is abutted and connected to one end of b. After that, the self-propelled carriage 4 moves from the split rail 14 to the other traveling rail 5b and moves to the target shelf 33.

When the self-propelled carriage 4 is moved from one end of the other traveling rail 5b to one end of the one traveling rail 5a by using the delivery moving body 6a, the electric motor 28 is reversely driven. To be done.

In this way, since the transfer moving body 6a moves on the arcuate path portion 2, when the split rail 14 is separated from one end of the traveling rails 5a and 5b, the other end of the split rail 14 is moved. The rails 5a, 5b for traveling are not laterally (orthogonal) to one end of the rails 5a, 5b, but move laterally while displacing from one side to another (direction of arrow a).
Away from one end of. In addition, the other end of the split rail 14 is right next to one end of the traveling rails 5a and 5b (in the orthogonal direction).
Instead, it moves laterally while displacing from one side to the other (arrow B direction) and abuts on one end of the traveling rails 5a, 5b to be connected. Therefore, the other end of the split rail 14 does not slidably contact one end of each traveling rail 5a, 5b,
In addition, it is possible to eliminate the gap at the joint 41 between the other end of the split rail 14 and one end of the traveling rails 5a and 5b.

As a result, the self-propelled carriage 4 is moved by the traveling rail 5
Vibration at the time of transferring between one end of a and 5b and the split rail 14 of the transfer vehicle 6a is reduced, and one end of the traveling rails 5a and 5b and the other end of the split rail 14 are damaged by sliding contact. It is possible to prevent abrasion and generation of abnormal noise or vibration.

Similarly, as shown in FIG. 3, the self-propelled carriage 4 uses the other delivery moving body 6b to drive both traveling rails 5.
Passed between a and 5b. Also in this case, similarly to the above, one end of the split rail 14 does not slidably contact the other end of each traveling rail 5a, 5b, and one end of the split rail 14 and the other end of the traveling rails 5a, 5b. It is possible to eliminate the gap at the seam 42.

As a result, the self-propelled carriage 4 is moved to the rail 5 for traveling.
Vibration when transferring between the other ends of a and 5b and the split rail 14 of the transfer vehicle 6b is reduced, and the other ends of the traveling rails 5a and 5b and one end of the split rail 14 are damaged by sliding contact. It is possible to prevent abrasion, noise, vibration, etc.

Similarly, since a joint between the power supply rails (not shown) on the traveling rails 5a and 5b and the power supply rails (not shown) on the split rail 14 side can be eliminated,
It is possible to prevent the current collector (not shown) from coming off the power supply rail.

When carrying out maintenance and inspection of the self-propelled carriage 4,
The self-propelled carriage 4 is stopped on the take-out split rail 13, and the take-out moving body 12 is manually moved to the maintenance rail 11 side as shown by a virtual line (c) in FIG. As a result, the take-out split rail 13 is separated from the traveling rail 5b and connected to one end of the maintenance rail 11. Then, the self-propelled carriage 4 may be transferred from the split rail 13 for extraction onto the rail 11 for maintenance for maintenance and inspection.

[0029]

As described above, according to the present invention, the transfer moving body is supported and guided by the arc-shaped transfer rail and moves along the arc-shaped path portion. As a result, the other end of the split rail of the transfer vehicle moves laterally while displacing from one side to the other side of the one end of the traveling rail instead of being directly lateral (orthogonal direction) to one end of the traveling rail. Abutted and connected. Therefore, the other end of the split rail does not come into sliding contact with one end of the travel rail, and a gap between the other end of the split rail and one end of the travel rail can be eliminated.

Further, when the split rail is separated from the traveling rail, the other end of the split rail is displaced laterally from one end of the traveling rail, not from the right side (orthogonal direction) but from the other side. It moves and separates from one end of the rail for traveling. Therefore, the other end of the split rail does not come into sliding contact with one end of the travel rail, and a gap between the other end of the split rail and one end of the travel rail can be eliminated.

Since the gap between the other end of the split rail and one end of the traveling rail can be eliminated in this way,
Vibration when the self-propelled carriage transfers between the traveling rail and the split rail can be reduced, and one end of the traveling rail and the other end of the split rail are damaged and worn by sliding contact, and abnormal noise and vibration occur. Can solve problems such as

When the power supply rails are provided on the traveling rail side and the split rail side and the current collectors are provided on the self-propelled carriage side, the power supply rails on the traveling rail side and the power supply rails on the split rail side are similarly provided as described above. Since the gap between the joint and can be eliminated, it is possible to prevent the current collector from coming off the power supply rail.
