Abstract

(57) [Abstract] [Purpose] To clean overhead wires of overhead type article conveyors. [Structure] When the traveling vehicle 4 travels while the cleaner roller 22 is in contact with the overhead wire 11, the overhead wire 11 is cleaned by the cleaner roller 22 that rotates as the traveling wheels 5 rotate.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an overhead wire cleaning device provided in a traveling vehicle of an overhead article transporting device.

[0002]

[Prior art]

 The following is known as a conventional overhead type article conveying apparatus. That is, a guide rail provided above, a traveling vehicle traveling along the guide rail, an elevating frame provided on the traveling vehicle so as to be vertically movable, and an article hanging hand provided on the elevating frame. A power supply overhead wire provided along the guide rail for supplying electricity to electric equipment such as a traveling motor mounted on a traveling vehicle and a signal overhead wire for transmitting a control signal to the electric equipment (hereinafter, simply referred to as an overhead wire And a sliding contact provided on the traveling carriage that makes sliding contact with these overhead lines.

[0003]

[Disadvantages of the prior art]

 The conventional overhead type article conveying apparatus has the following drawbacks. In other words, since there was no mechanism for cleaning the overhead wire, there was the drawback that dust and other particles could adhere to the overhead wire, causing momentary power interruptions and troubles such as signal errors when the slider passed through that area. It was

[0004]

[Means for eliminating the above drawbacks]

 This invention adopts the following means in order to solve the above-mentioned drawbacks. This invention is an overhead line cleaning device provided in a traveling vehicle of an overhead type article transporting apparatus, which has a cleaner roller urged in the direction of contacting the overhead line and a suction roller provided close to the cleaner roller. It has a container.

[0005]

Operation of the Invention This invention has the following functions. The overhead wire can be cleaned with a cleaner roller, and dust and other deposits removed by the cleaner roller are collected by a filter with a suction device.

【Example】

 The present invention will be described below based on an embodiment shown in the drawings. In this specification, the front means the right side of FIG. 1, the rear means the left side of the figure, the left means the back side of FIG. 1, and the right means the front side.

A guide rail 3 is provided on the ceiling 1 via a suspending tool 2, traveling wheels 5 are placed on the guide rail 3, and a traveling vehicle 4 is suspended along the guide rail 3 so that the traveling vehicle 4 can travel freely. There is. Of the traveling wheels 5, one on the front side or the rear side is a drive wheel that is rotated by a motor (not shown) that can rotate in the forward and reverse directions. An elevating frame 7 is provided on the traveling vehicle 4 so as to be vertically movable by a known elevating device (not shown), and an elevating frame 7 is provided with a known article hanging hand 8. It is designed to be retained.

A required number of overhead wires 11 are provided along the guide rails 3, and a sliding contactor 12 slidingly contacting these overhead wires 11 is provided on the traveling vehicle 4.

A pair of left and right arms 16 are provided with their free ends rearward on an axle 6 in which the rear traveling wheels 5 are not fitted and the rotatable center of the traveling vehicle 4 is oriented in the left-right direction. It is provided so as to be vertically swingable so that at least one of the arms 16 is biased by a spring 17 so as to raise its free end upward. A rotary shaft 18 is rotatably fitted to the free end of the arm 16, and a wheel 19 is fixed to the rotary shaft 18 so that a wheel 19 paired with the wheel 19 rotates together with the traveling wheel 5. The endless chain 20 is stretched over both wheels 19 and fitted onto the wheel 6. With such a configuration, when the traveling wheels 5 rotate as the traveling vehicle 4 travels, the rotating shaft 18 rotates. A cleaner roller 22 having an outer peripheral surface made of a polishing cloth, for example, is fitted on the rotary shaft 18, and the cleaner roller 22 is brought into contact with the overhead wire 11 by the action of the spring 17. Alternatively, the arm 16 may be swung by a linear solenoid (not shown) so that the cleaner roller 22 can be separated from and contacted with the overhead wire 11.

With the above-described configuration, when the traveling vehicle 4 travels in a state where the cleaner roller 22 is in contact with the overhead line 11, the overhead line 11 is removed by the cleaner roller 22 that rotates as the traveling wheels 5 rotate. Can be cleaned.

A suction device 24 having a suction port 25 facing the cleaner roller 22 is provided in the traveling vehicle 4. The suction device 24 has a discharge port 26 covered with a filter 27 and a fan 28. With such a configuration, the adhered matter such as dust removed from the overhead wire 11 by the cleaner roller 22 is drawn into the suction device 24 so that the adhered matter does not scatter.

[0012]

[Advantages of the embodiment]

 The above embodiment has the following advantages. (1) Since the cleaner roller 22 is rotated by the traveling of the traveling vehicle 4, it is possible to more efficiently remove the deposits on the overhead wire 11. (2) Since the cleaner roller 22 is rotated by using the rotational force of the traveling wheels 5, a special motor is not required to rotate the cleaner roller 22, so the cost can be reduced. Can be done.

[0013]

[Effect of device]

 The present invention has the following effects due to the above-described configuration. Since the cleaner roller can clean the overhead wire, it is possible to prevent the temporary interruption of power supply and the trouble such as signal error, which are caused by dust adhering to the overhead wire. Dust and other deposits removed from the overhead wire by the cleaner roller can be drawn into the aspirator to prevent the deposits from scattering, so the surrounding air is not polluted and cleanliness can be maintained. .
