Description

Technology Field

[0001] The present invention relates to a vehicle cleaning device, and more specifically, to a vehicle cleaning device for cleaning a vehicle that travels along a travel rail and transports an object. Background Technology

[0002] Generally, a ceiling transport device transports an object as multiple vehicles travel along a rail. Since the vehicles travel repeatedly along the rail, particles remain on the vehicles due to friction between the vehicles' travel wheels and the rail.

[0003] A vehicle cleaning device is used to remove the above particles. The vehicle cleaning device sprays air toward the vehicle and sucks in and discharges the particles scattered by the air.

[0004] However, since the particles are attached to the vehicle by electrostatic force, it is difficult to effectively remove them using only the air jet and suction. Furthermore, particles scattered by the air may not be removed and may reattach to the vehicle. Therefore, it is necessary to effectively remove the particles. Prior art literature

[0025] FIG. 1 is a schematic front cross-sectional view for explaining a vehicle cleaning device according to one embodiment of the present invention, FIG. 2 is a schematic side cross-sectional view for explaining the vehicle cleaning device shown in FIG. 1, and FIG. 3 is a front view for explaining another example of an opening and closing part shown in FIG. 1.

[0026] Referring to FIGS. 1 to 3, the vehicle cleaning device (100) cleans the vehicle (10) to remove particles attached to the vehicle (100). The vehicle (10) can travel along a driving rail (20) and transport an object (30).

[0027] The vehicle cleaning device (100) may include a chamber (110), a spray unit (120), a suction unit (130), and an electrostatic removal unit (140).

[0028] The chamber (110) provides a space for cleaning the vehicle (10). The chamber (110) may be configured to accommodate the driving rail (20) inside.

[0029] Specifically, the chamber (110) is provided with an inlet and an outlet. The running rail (20) can pass through the inlet, the interior, and the outlet of the chamber (110). The vehicle (10) travels along the running rail (20) and is introduced into the chamber (110) through the inlet, and is discharged from the chamber (110) through the outlet when the cleaning of the vehicle (10) is completed. The vehicle (10) can be easily introduced into the chamber (110) and easily discharged from the chamber (110), and there is no need to provide separate means for the introduction and discharge of the vehicle (10).

[0030] The inlet and outlet of the chamber (110) may be provided with an opening / closing part (112) for opening and closing the inlet and outlet. Accordingly, the interior of the chamber (110) is sealed, and foreign substances can be prevented from entering the interior of the chamber (110).

[0031] As illustrated in FIG. 1, the opening / closing part (112) may be a curtain. The curtain is in the form of a plurality of overlapping strips, and each strip may have one end fixed to the top of the chamber (110) at the entrance and the exit of the chamber (110), and the other end opposite to the one end may be draped to the bottom of the chamber. The opening / closing part (112) may be opened / closed by the force of the vehicle (10) moving.

[0032] Since the opening / closing part (112) is opened and closed by the driving force of the vehicle (10), a separate driving unit for opening and closing the opening / closing part (112) is unnecessary. Therefore, the configuration of the vehicle cleaning device (100) can be simplified.

[0033] The above curtain may be made of any one of antistatic vinyl, grounded metal, and antistatic plastic. Therefore, even if the opening / closing part (112) comes into contact with the vehicle (10) passing through the entrance and the exit, it is possible to prevent static electricity from being generated on the vehicle (10) or the opening / closing part (112).

[0034] As illustrated in FIG. 3, the opening / closing unit (112) may include shutters (113) for opening and closing the entrance and the exit, respectively, and driving units (116) for driving the shutters (113), respectively.

[0035] Each of the above shutters (113) may include an upper shutter (114) and a lower shutter (115).

[0036] The upper shutter (114) is provided above the travel rail (20) and opens and closes the upper part of the travel rail (20) at the entrance and the exit. The lower shutter (114) is provided below the travel rail (20) and opens and closes the lower part of the travel rail (20) at the entrance and the exit.

[0037] The upper shutter (114) and the lower shutter (115) may be configured to move along the up-and-down direction, move along the left-and-right direction, or rotate to open and close the entrance and the exit.

[0038] When each of the above shutters (113) blocks the entrance and the exit, the upper shutter (114) and the lower shutter (115) can be engaged with each other.

[0039] When the above opening / closing unit (112) includes the shutters (113) and the driving unit (116), the above opening / closing unit (112) can reliably seal the inlet and outlet of the chamber (110). Accordingly, when cleaning the vehicle (10), it is reliably possible to prevent the particles from leaking out of the chamber (110) through the inlet and outlet.

[0040] Meanwhile, the above-mentioned driving rail (20) may consist of a main rail and an auxiliary rail. On the main rail, the vehicle (10) transports the object (30), and on the auxiliary rail, maintenance or cleaning of the vehicle (10) may be performed.

[0041] The chamber (110) may be positioned to accommodate the auxiliary rail, rather than the main rail, among the running rails (20). Since the chamber (110) is provided on the auxiliary rail, the vehicle cleaning device (100) does not interfere with the vehicle (10) transporting the object (30).

[0042] The above injection unit (120) is provided inside the chamber (110) and injects air toward the vehicle (10).

[0043] The above-mentioned injection unit (120) may include a plurality of nozzles, and the nozzles may be connected to a pump or blower for providing the air through a first pipe. The nozzles may be positioned on the upper surface and side of the inside of the chamber (110). In particular, the nozzles provided on the side of the inside of the chamber (110) may be positioned at various heights. Thus, the nozzles can uniformly spray the air into the vehicle (10).

[0044] The suction unit (130) is provided inside the chamber (110) and sucks in the particles scattered from the vehicle (10) by the air sprayed from the spray unit (120).

[0045] Specifically, the suction unit (130) includes a plurality of fans (132) for sucking in the particles along with the air, and the fans (132) are connected to a second pipe and can discharge the particles to the outside through the second pipe. Additionally, the second pipe may be further equipped with a pump (not shown) for sucking in the particles and the air. The second pipe may be equipped with a filter (not shown) for capturing the particles.

[0046] Meanwhile, the suction unit (130) may be positioned at a height where the air is sprayed from the spray unit (120). Accordingly, the suction unit (130) can immediately suck in the particles scattered by the sprayed air and prevent the particles from reattaching to the vehicle (10).

[0047] The above electrostatic removal unit (140) is provided inside the chamber (110) and removes electrostatic charge from the particles attached to the vehicle (10).

[0048] Specifically, the electrostatic removal unit (140) irradiates X-rays toward the air inside the chamber. The X-rays may be soft X-rays. Soft X-rays mean that the penetrating power of the X-rays is about 0.12 to 12 keV.

[0049] The above X-rays form the air particles into positive and negative ions, and the positive and negative ions neutralize and remove the static electricity of the particles. Therefore, it is possible to prevent the particles from attaching to the vehicle (10) by electrostatic force.

[0050] Since the static electricity of the particles is removed, the particles of the vehicle (10) can be effectively removed by only the air injection of the injection unit (120) and the suction of the suction unit (130). Industrial applicability

[0051] As described above, the vehicle cleaning device according to the present invention facilitates the introduction and discharge of the vehicle by allowing the vehicle to be introduced into and discharged from the chamber along the driving rail.

[0052] In the case where the above opening / closing part is the curtain, even if the above opening / closing part rubs against the vehicle passing through the entrance and the exit, it is possible to prevent static electricity from being generated in the vehicle or the above opening / closing part.

[0053] When the above-mentioned opening and closing unit includes the shutters and the driving units, the above-mentioned opening and closing unit can reliably seal the inlet and outlet of the chamber. Therefore, when cleaning the vehicle, it is possible to prevent the particles from leaking out of the chamber through the inlet and outlet.

[0054] Since the suction unit is positioned at a height where the air is sprayed from the spray unit, the suction unit can directly suck in the particles scattered by the air. Therefore, the reattachment of the particles to the vehicle can be suppressed.

[0055] Since the above-mentioned electrostatic removal unit removes the electrostatic charge of the particles, it is possible to prevent the particles from attaching to the vehicle by electrostatic force, and the particles can be effectively removed by only the injection of air and the suction.

[0056] Although the present invention has been described above with reference to preferred embodiments, those skilled in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and scope of the invention as set forth in the following claims.
