[Figure 6] FIG. 4 is a side view showing the cleaning device shown in FIG. 3. [Figure 7] FIG. 4 is a plan view of the cleaning device shown in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, a cleaning device for a painting carriage according to an embodiment will be described with reference to the accompanying drawings. However, the dimensions, materials, shapes, relative positions, etc. of the components described as the embodiment or shown in the drawings are merely illustrative examples and are not intended to limit the scope of the present invention.

[0021] The cleaning device for a painting carriage according to the embodiment is intended to remove paint stains accumulated on a connection portion connecting the lower half and upper half of a painting carriage on which an object to be painted is mounted.

[0022] 1, for example, an object to be painted is an automobile body 300, and a painting cart 100 on which the object to be painted is mounted is connected to a conveyor chain 200 that circulates within an automobile manufacturer's painting factory and circulates within the painting factory. The conveyor chain 200 is arranged along the floor of the painting factory, and circulates above the conveyor chain 200.

[0023] The lower half 110 of the painting carriage 100 is provided with a bar 111 extending in the moving direction of the painting carriage 100 (the front-rear direction of the painting carriage 100) and running wheels 113 supporting the painting carriage 100, while the upper half 130 of the painting carriage 100 is provided with a frame 131 supporting an object to be painted. As shown in Fig. 2, the connecting portion 150 is U-shaped when viewed from the front and has a lower horizontal portion 151 extending in the vehicle width direction and connected to the lower half 110 at its center, an upper horizontal portion 153 extending in the vehicle width direction along the underside of the frame 131 and connected to the upper half 130 as a whole, and a support portion 155 arranged biased to one side in the vehicle width direction (the right side in Fig. 2) and connecting the lower horizontal portion 151 and the upper horizontal portion 153. Guide wheels 157 for supporting the painting carriage 100 are provided on both ends of the lower horizontal portion 151, and the guide wheels 157 are supported by guide rails (not shown).

[0024] As shown in Fig. 3 to Fig. 5, the cleaning device 1 for the paint carriage 100 according to the embodiment includes a moving mechanism for moving the paint carriage 100, and a pair of files 2, 3 arranged opposite to each other along the moving direction of the paint carriage 100 at the height of the connecting part 150 so as to sandwich the connecting part 150 from a direction intersecting the moving direction of the paint carriage 100. For example, the moving mechanism for moving the paint carriage 100 is a conveyor chain 200 that circulates in a paint factory of an automobile manufacturer, and the direction intersecting the moving direction of the paint carriage 100 is a direction perpendicular to the circulating direction of the conveyor chain 200. Each of the pair of files 2, 3 is a file that can scrape off paint stains accumulated on the connecting part 150 as the paint carriage 100 moves, and a relatively coarse rack gear-shaped file is used in which the moving direction of the paint carriage 100 is the longitudinal direction and the extending direction (height direction) of the connecting part 150 is the width direction.

[0025] According to the cleaning device 1 for the painting carriage 100 of the embodiment described above, the pair of files 2, 3 can scrape off paint stains accumulated on the connecting portion 150 as the painting carriage 100 moves.

[0026] As shown in Fig. 7, at least one of the files 2, 3 can move closer to the other file 2, and an elastic force acts toward the other file 2. For example, the file 3 on the outside of the connecting part 150 (on the right side in Fig. 4) can move closer to the file 2 on the inside of the connecting part 150 (on the left side in Fig. 4), and an elastic force acts toward the file 2 on the inside of the connecting part 150. For example, the file 3 on the outside of the connecting part 150 can slide closer to the file 2 on the inside of the connecting part 150 by the pair of sliders 31, 33, and an elastic force acts toward the file 2 on the inside of the connecting part 150 by the elastic restoring force of the compression coil spring 35 provided in the center of the longitudinal direction of the file 3.

[0027] With this configuration, at least one of the files 3 is pressed against the connecting portion 150 on which paint stains have accumulated, so that the paint stains accumulated on the connecting portion 150 can be scraped off reliably by at least one of the files 3.

[0028] 6 and 7, the cleaning device 1 for the painting carriage 100 according to the embodiment includes a rotating brush 4 rotatably provided in the moving direction of the painting carriage 100 at a height position of the connecting part 150, a wheel 5 which rotates by being pressed against a bar 111 extending in the moving direction of the painting carriage 100, and a power transmission mechanism 6 which transmits the rotation of the wheel 5 to the rotating brush 4. For example, the power transmission mechanism 6 includes a chain 63 which transmits the rotation of the wheel 5 to a main shaft 61, and a chain 65 which transmits the rotation of the main shaft 61 to the rotating brush 4, and the rotation of the wheel 5 is transmitted to the rotating brush 4 via the main shaft 61.

[0029] With this configuration, when the painting carriage 100 is moved by the movement mechanism, the wheel 5 is pressed against and rotates against the bar 111 extending in the direction of movement of the painting carriage 100. The rotation of the wheel 5 is transmitted to the rotating brush 4 by the power transmission mechanism 6, causing the rotating brush 4 to rotate. In this way, the connecting portion 150 from which the paint stains have been scraped off can be finished by the rotating brush 4. In addition, since the rotating brush 4 rotates as the painting carriage 100 is moved by the movement mechanism, there is no need to provide a motor or the like just to rotate the rotating brush 4, and the cleaning device 1 can be made inexpensively.

[0030] The rotating brush 4 is rotatable so as to approach the connecting portion 150, and an elastic force acts on the rotating brush 4 so as to approach the connecting portion 150. For example, the rotating brush 4 is rotatable about the main shaft 61 so as to approach the connecting portion 150, and an elastic force acts on the rotating brush 4 so as to approach the connecting portion 150 due to the elastic restoring force of the torsion coil spring 41 provided around the main shaft 61.

[0031] With this configuration, the rotating brush 4 is pressed against the connecting portion 150 from which the paint stains have been scraped off, so that the connecting portion 150 from which the paint stains have been scraped off can be reliably finished by the rotating brush 4.

[0032] The wheel 5 is rotatably movable so as to approach the bar 111, and an elastic force acts on the wheel 5 so as to press the wheel 5 against the bar 111. For example, the wheel 5 is rotatably supported by a wheel bracket 55 which rotates about a pin 53 provided on a mounting bracket 51 which is attached to the traveling rail 210 on which the running wheels 113 travel. An elastic force acts on the wheel 5 towards the bar 111 due to the elastic restoring force of a compression coil spring 57 provided between the mounting bracket 51 and the wheel bracket 55.

[0033] With this configuration, the wheel 5 is pressed against the bar 111, and the wheel 5 rotates reliably when the painting cart 100 is moved by the moving mechanism. This also reliably rotates the rotating brush 4, so that the connecting portion 150 from which the paint stains have been scraped off can be reliably finished by the rotating brush 4.

[0034] A belt conveyor 7 is provided below the pair of files 2, 3, and circulates in a direction intersecting the moving direction of the painting carriage 100 by the power transmitted from the power transmission mechanism 6. For example, the belt conveyor 7 is a belt conveyor that circulates in a direction perpendicular to the moving direction of the painting carriage 100, and as shown in Fig. 6, a countershaft 75 to which power is transmitted from the main shaft 61 by bevel gears 71, 73, and a chain 77 that transmits power from the countershaft 75 to the belt conveyor 7 are provided between the power transmission mechanism 6 and the belt conveyor 7.

[0035] With this configuration, the paint stains scraped off by the pair of files 2, 3 can be discharged by the belt conveyor 7 in a direction intersecting the moving direction of the painting cart 100. In addition, since the belt conveyor 7 is circulated by the power transmitted from the power movement mechanism, there is no need to provide a motor or the like just for circulating the belt conveyor 7, and the cleaning device 1 can be made inexpensive.

[0036] The present invention is not limited to the above-described embodiment, and includes modifications to the above-described embodiment and appropriate combinations of these modifications. [Explanation of symbols]
