[Prior art]

 As an overhead traveling vehicle device having a traverse function, the applicant of the present application has already proposed a station for an overhead traveling vehicle that enables overtaking of overhead traveling vehicles in a station.

FIG. 4 is a perspective view of a traverser used in a station of this overhead traveling vehicle as seen from below.

In FIG. 1, reference numeral 1 is a base fixed to the ceiling. Relay rails 2a and 2b are arranged in parallel in the lower portion of the base 1 at regular intervals, and are provided so as to be connectable to the main runway R 1, respectively. Reference numeral 3 is a slider provided between the base 1 and the relay rails 2a and 2b, and the relay rails 2a and 2b are slid in the direction of arrow C in the figure by a drive mechanism (not shown).

The station of the overhead traveling vehicle is arranged below the position deviated from the main runway R (in the direction of arrow D in the figure).

Overtaking between overhead traveling vehicles by such a traverser is performed as follows.

First, the preceding overhead traveling vehicle is stopped on the relay rail 2a. Next, the slider 3 is driven to slide the relay rails 2a and 2b in the direction of arrow C1 in the figure. As a result, the overhead traveling vehicle moves to a position deviated from the main track R, and the relay rail 2b is connected to the main track R instead.

As a result, the succeeding overhead traveling vehicle can travel on the main track R via the relay rail 2b and can pass the preceding overhead traveling vehicle.

Therefore, while the preceding overhead traveling vehicle is working with the station, it is possible to cause the succeeding overhead traveling vehicle to go first and realize efficient traveling. it can.

[Problems to be solved by the device]

 In the above-mentioned conventional overhead traveling vehicle device, since the station is located below the position off the main track, the overhead traveling vehicle is traversed laterally from the main track, and then the loading / unloading work of the load is carried out. Had to do.

Therefore, when carrying in / out the work, the time for traversing the overhead traveling vehicle to the side is wasted.

An object of the present invention is to solve the above problems, to enable efficient traveling of an overhead traveling vehicle, and to reduce the time required for loading and unloading work. To provide a device.

[0013]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention includes a relay rail that is movable in a vertical direction, and an auxiliary rail that moves along with the movement of the relay rail is vertically above the relay rail and between the relay rail and the auxiliary rail. It has a structure in which the overhead traveling vehicle is placed at a distance that allows passage.

[0014]

[Advantages] Since the overhead traveling vehicle device of the present invention is configured as described above, the following advantages are achieved.

That is, the auxiliary rail is arranged above the relay rail in the vertical direction with a space allowing the overhead traveling vehicle to pass through the relay rail, and moves along with the movement of the relay rail. Therefore, when the relay rail is moved downward toward the station, the auxiliary rail moves vertically downward and is connected to the main track.

Accordingly, if the overhead traveling vehicle is stopped on the relay rail and the intermediate rail is moved downward toward the station, the succeeding overhead traveling vehicle travels on the main runway via the auxiliary rail. It is possible to overtake an overhead traveling vehicle that is stopped on the relay rail.

Therefore, according to the overhead traveling vehicle device of the present invention, while the preceding overhead traveling vehicle is working with the station, the succeeding overhead traveling vehicle can be moved ahead. Therefore, it is possible to realize efficient traveling of the overhead traveling vehicle.

Moreover, since the overhead traveling vehicle on the relay rail moves downward toward the station, the traveling time is not wasted when carrying in / out the work, rather the vehicle approaches the station instead. This has the effect of shortening the entry time.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing an embodiment of an overhead traveling vehicle device according to the present invention, and FIG. 2 is a left side view.

In these drawings, the overhead traveling vehicle device according to the present embodiment includes a relay rail 10, an auxiliary rail 11, a frame body 12, and a lifting drive unit 13, and is located above the overhead traveling vehicle station. It is provided in.

The relay rail 10 is connectable to and detachable from the main runway R, and has a length that allows the overhead traveling vehicle to stop. The relay rail 10 is attached to the center of a lower portion 12a of a frame body 12 formed in a hollow structure having a square shape when viewed from the front.

The auxiliary rail 11 has the same shape and length as the relay rail 10. As shown in FIG. 1, the auxiliary rail 11 is attached to the center of the upper portion 12b of the frame body 12, and is above the relay rail 10 in the vertical direction, and at a distance between the overhead rail 1 and the relay rail 10 at which the overhead traveling vehicle 1 can travel. Are separated from each other.

Both sides 12c, 12c of the frame body 12 are formed with a wide interval so that the left and right of the overhead traveling vehicle 1 do not come into contact with each other when the overhead traveling vehicle 1 passes through the auxiliary rail 11.

The frame body 12 is normally held at a position where the relay rail 10 is connected to the main runway R by an elevating / lowering drive unit 13 described later.

The elevating / lowering drive unit 13 includes a drive motor 14, a winding unit 15 driven by the drive motor 14, and four wires wound around the winding unit 15 and the ends of which are connected to the frame body 12. It consists of 16.

The drive motor 14 is fixed to the ceiling of a building or the like, and its rotation is controlled by a control unit and an encoder (not shown) to drive the winding unit 15. The four wires 16 are guided via a pulley 16a.

As a result, when the drive motor 14 is driven, the four wires 16 are wound up or sent out by the winding section 15, and the frame 12 is moved up and down.

Next, the operation of the overhead traveling vehicle device described above will be described with reference to FIGS. 3 (a) to 3 (c). Here, it is assumed that the leading overhead traveling vehicle A is programmed to carry in and out the load at the station, and the succeeding overhead traveling vehicle B is programmed to pass through this station. To do.

The overhead traveling vehicle A travels on the main traveling path R, then transfers to the relay rail 10 on the station and stops (see FIG. 3A). After that, the drive motor 14 is driven by the control unit (not shown), the wire 16 is sent out, and the frame 12 is lowered. As a result, the relay rail 10 is disengaged from the main tracks R and R2, and instead, the auxiliary rail 11 is connected to the main tracks R and R2 (see FIG. 3B). At the same time, the overhead traveling vehicle A lowers the elevating frame 3 to the station to start loading / unloading work.

Next, the following overhead traveling vehicle B that has traveled on the main track R travels from the main track R through the auxiliary rail 11 to the main track R2. As a result, the overhead traveling vehicle B 1 can overtake the overhead traveling vehicle A 1 and go ahead (see FIG. 3C).

As described above, according to the overhead traveling vehicle device of the present embodiment, by moving the preceding overhead traveling vehicle A in the vertical direction on the relay rail 10, the succeeding overhead traveling vehicle A 1 is moved through the auxiliary rail 11. Car B can be passed. Therefore, while the preceding overhead traveling vehicle A is working with the station, it can be made to go ahead of the succeeding overhead traveling vehicle B, thereby realizing efficient traveling of the overhead traveling vehicle. Can

Moreover, since the overhead traveling vehicle A on the relay rail 10 moves downward toward the station, traveling time is not wasted when carrying in / out work, and rather the vehicle approaches the station. It is possible to shorten the carry-in / out time.

Further, in this embodiment, the elevating frame 3 of the overhead traveling vehicle A moves up and down at the same time as the relay rail 10 moves up and down, so that the carry-in / out cycle time can be further shortened. However, this is not particularly limited, and the elevating frame 3 may be moved up and down after the elevating of the relay rail 10 is completed.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the invention.
