Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a coating device installed on road marking construction machines that stores and discharges the paint to be applied. With regard to A coating for road marking construction machines that keeps the liquid level of the paint flowing into the cloth box at a specified position. Relating to cloth devices.

0002

[Conventional technology]

Traditionally, paint for road markings has been applied using a hand-pushing machine; The cloth device has a lever-type shutter that can be opened and closed provided at the discharge port of the coating tank. − is operated by a worker to open and close, and the road material to be coated flows into the coating box below. Adjustment of the liquid level flowing into the application box is a manual method that requires humans to visually adjust the level. Ta.

0003

[Problem that the idea aims to solve]

With this conventional coating device that manually opens and closes the shutter, the liquid level in the coating box is Requires frequent opening and closing of the shutter to keep it in place, making it difficult to operate the applicator A skilled worker or persons must be assigned to carry out the The installation cost is high, and if the shutter is opened and closed manually, the application bottle is too expensive. It is difficult to maintain the liquid level in the box at a specified position, and therefore the position of the liquid level during construction is difficult to maintain. This causes a pressure difference, which manifests as a variation in the amount of paint applied, resulting in a stable surface on the road surface. In addition, in recent years, road marking line construction machines have become self-propelled. Accordingly, automation of coating equipment has been desired.

0004

[Means to solve the problem]

Means for solving the above problems will be explained below using diagrams corresponding to examples. do.

[0005] The present invention is a paint tank that dissolves paint (7) installed in a road marking construction machine (1). (2) and a coating box (4) provided below the discharge port (21) of the paint tank (2). ) and a liquid level detector ( 5) and an opening actuated by at least the liquid level detector (5) to open and close the discharge port (21). and a closing means (6) to automate the opening and closing of the discharge port (21) of the paint tank (2). In both cases, the liquid level of the paint (7) in the application box (4) was kept at a predetermined position. .

[0006]

[Effect]

The paint (7) stored in the paint tank (2) is first turned into a cylinder using a start switch, etc. - By operating the control circuit (65) that controls the circuit (62), the cylinder piston The cylinder rod (62a) moves upward and the shutter (61) connected to the cylinder rod (62b) When fully opened, the empty air below flows from the discharge port (21) of the paint tank (2) through the chute (22). It flows into the application box (4).

[0007] Eventually, the liquid level of the paint (7) flowing into the coating box (4) reaches a predetermined position. Then, the pressure-type liquid level detector (5) installed there detects the pressure, and the pressure valve (52) is activated by pressure, transmits the pressure information to the control circuit (65) of the cylinder (62), and the control circuit The cylinder rod (62b) returns based on the command from the road (65), and the shutter The tar (61) also returns to close the discharge port (21).

[0008] After that, when installing, if the amount of paint (7) used is normal, remove the opening/closing plate (42). When the open paint (7) is discharged from the outlet (41) of the application box (4), the liquid gradually When the level drops below a certain level, the pressure valve (52) of the liquid level detector (5) will reduce the pressure. The information is transmitted to the control circuit (65), and the cylinder piston (62a) moves upward. Move, fully open the shutter (61), and pour the paint from the paint tank (2) into the coating box (4). Paint (7) is supplied.

[0009] When the paint (7) in the coating box (4) reaches a predetermined level, the liquid level is checked. The alarm (5) is activated, the shutter (61) is closed as described above, and the same operation will not be performed thereafter. Repeat.

0010 Next, if a small amount of paint (7) is used during construction, fill it in the application box (4). Since the liquid level decreases slowly, it reaches the specified position and shuts down based on the pressure information mentioned above. When the tar (61) opens, a large amount of paint (7) will suddenly and rapidly enter the coating box (4). Because of this, the paint (7) may overflow from the coating box (4). Ru. That is, in this case, the movement of the cylinder piston (62a) is Apply the brake to the cylinder piston (62a) to stop it in the middle position, and The opening degree of the shutter (61) connected to the piston (62a) is set to half open, and the above-mentioned problems are solved. It corresponds to

[0011] In addition, the manual cylinder position adjuster (64) installed at the top of the cylinder (62) By turning the handle (64c), the threaded rod (64b) moves up and down while being turned. The entire cylinder (62) connected to the rod (64b) can be moved up and down to change its position.

0012 Therefore, when switching to the intermediate position adjuster (63), the opening degree of the shutter (61) is Even if this is not the case, by using this manual cylinder position adjuster (64), you can The opening degree of the shutter (61) can be adjusted.

[0028]

[Effect of the idea]

The present invention has the following effects.

[0029] The shutter (61) that opens and closes the discharge port (21) of the paint tank (2) is connected to the cylinder (6). By using the automatic opening/closing method driven by step 2), there is no need for personnel to open and close the operation. It can save labor and reduce construction costs.

[0030] During construction, the paint (7) maintains the specified liquid level in the coating box (4) and maintains the liquid pressure. Since there is no fluctuation, the discharge amount of the application box (4) is always constant, and therefore the road surface The partition line constructed above is applied to a predetermined uniform thickness, making construction management easier.

[0031] Attach intermediate position adjuster (63) and manual cylinder position adjuster (64) to cylinder (62). By providing this, the shutter (61) can be used whenever a small amount of paint (7) is used during construction. With the shutter (61) open and closed, do not open and close the dispensing bottle repeatedly. The paint tank (4) is continuously supplied from the paint tank (2) while maintaining the specified liquid level at all times. This reduces friction caused by the movement of the shutter (61), cylinder (62), etc., and increases durability. Improves sex.

[0032] Since the liquid level detector (5) is a pressure type, the paint ( 7) Even if the viscosity of increase rate.
