Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an overhead traveling vehicle system. In particular, it relates to an overhead traveling vehicle system capable of switching a relay rail for branching without using a vertical device.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, systems using overhead traveling vehicles have been known as systems for transporting luggage from station to station in factories and warehouses. In many cases, the tracks of overhead traveling vehicles are complicatedly branched according to the process in the factory, and a branch relay rail using a vertical device is installed at the branching part.

[0003]

[Problems to be solved by the device]

 The above-described conventional overhead traveling vehicle system has the following problems.

Since the vertical device is arranged on the ceiling of a building or the like, and the relay rail for branching is moved in the vertical direction, in the place where the vertical device is arranged, the space below the vertical device is set. It was not possible to use it.

Further, the vertical device has only the function of moving the relay rail for branching, and has no other effective function. Therefore, the installation space for the vertical device itself was wasted.

The object of the present invention is to solve the above problems, to efficiently use the space at the branching portion, and not only to move the relay rail for branching, but also to It is an object of the present invention to provide an overhead traveling vehicle system having a branching device capable of effectively utilizing the above.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides at least two upper and lower tracks to which a vertically movable branch relay rail is connected, and another aerial vehicle runs above these tracks. The other rail is arranged, and the relay rail is moved up and down by using the ascending / descending platform of the overhead traveling vehicle traveling on the other rail.

[0008]

[Operation effect]

 Since the overhead traveling vehicle system of the present invention has the above-mentioned configuration, it has the following operational effects.

That is, another track is arranged above the upper and lower two-stage tracks to which the branch relay rails are connected, and by using the lifting platform of the overhead traveling vehicle that travels on this different track, Since the relay rail can be moved in the vertical direction, when switching the relay rail, stop the overhead traveling vehicle above the relay rail and grasp the relay rail by the work means of the lifting platform. After that, the relay rails can be switched by raising and lowering the elevator table.

As described above, according to the overhead traveling vehicle system of the present invention, it is possible to branch by using the lifting platform of the overhead traveling vehicle traveling on another track as a branching device without using a vertical device as in the related art. Since the relay rails for use in the system can be switched, the space for the branch can be operated efficiently. Moreover, the overhead traveling vehicle that switches the relay rails for branching does not only function as a branching device that switches the relay rails, but it is also possible to transfer luggage between stations, etc. Can be achieved.

【Example】

 Embodiments 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 system according to the present invention.

In the figure, R1 and R2 are upper and lower two-stage tracks suspended from the ceiling of a building or the like. Reference numeral 1 is a relay rail for branching that is movable in the vertical direction, and is connected to either the track R1 or the track R2. Reference numeral 2 denotes a coupling device provided on each of the tracks R1 and R2, and includes a coupling pin 3 and a driving unit 4 including a motor for sliding the coupling pin 3. The engagement pin 3 projects toward the relay rail 1 (in the direction of the arrow X in the drawing) by the operation of the driving means 4, and is engaged with the guide roller 5 provided on the relay rail 1.

R3 is another track arranged above the tracks R1 and R2, and an overhead traveling vehicle 10 different from the overhead traveling vehicle 20 traveling on the tracks R1 and R2 runs. Reference numeral 11 is an elevator of the overhead traveling vehicle 10, and chucks 12 and 12 are provided as working means. The chucks 12 and 12 are adapted to engage with the hook portions 13 and 13 provided on the upper portion of the relay rail 1 to hold the relay rail 1.

Next, an operation of branching the relay rail 1 from the track R1 to the track R2 will be described as an example.

First, the overhead traveling vehicle 10 traveling on the track R 3 is stopped at a predetermined position above the relay rail 1. Then, the elevating table 11 is lowered to engage the chucks 12, 12 with the hook portions 13, 13 of the relay rail 1.

Next, the drive means 4 of the connecting device 2 of the track R1 is operated to release the engagement of the engagement pin 3 engaged with the guide roller 5 of the relay rail 1. Then, the elevating table 11 is lowered to arrange the relay rail 1 between the tracks R2 and R2 (shown by a chain double-dashed line in the figure), and the engagement pin 3 of the connecting device 2 on the track R2 is guided to the relay rail 1. Engage with roller 5. As a result, the relay rail 1 is connected to the track R2 and the operation ends. The upper overhead traveling vehicle 10 that has finished the branching of the relay rail 1 travels to another branching portion (not shown) to branch off another relay rail, or travels to a station (not shown) to transfer the luggage. It is also possible to do so.

According to the above-described overhead traveling vehicle system of the present embodiment, by using the lifting platform 11 of the overhead traveling vehicle 10 traveling on another track R3, without using a vertical device as in the related art. Since the relay rail 1 for branching can be switched, the space for the branching portion can be efficiently operated. Moreover, the overhead traveling vehicle 10 that switches the relay rails 1 for branching does not only function as a branching device that switches the relay rails 1, but can also transfer goods at stations and the like, and It is also possible to switch the relay rails at the branching point, and effective use can be achieved.

Although the 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 gist of the present invention.
