Description

TECHNICAL FIELD The present invention relates to a lane marking coating apparatus used for drawing lane markings on roads, parking lots, and the like, and particularly uses cassette-type butane cylinders even in an environment where the outside air temperature is low and combustion efficiency decreases. Thus, a device capable of performing partition line coating is provided.

The lane marking coating device that has been widely used in the past supplies the paint filled in the paint tank located at the top of the four-wheel body to the box-type paint reservoir on the side while heating and melting it with the propane gas burner below. In addition, there are a front-pressing type that discharges from the paint discharge port provided on the side of the machine body and a back-drawing type that provides a discharge port on the four-wheel inner ring side. (See Patent Documents 1 and 2).

As previously seen in Patent Document 3, the present inventor proposed a low-cost apparatus that solves the above-mentioned difficulties and enables anyone to easily apply lane markings with high accuracy and safety. ing. The structure consists of two wheels that support the airframe during coating, and a burner that uses fuel provided in a fuel cylinder holder as a heating source below the paint tank that supplies paint to the discharge port on the rear inner ring side of the two wheels. A lane marking coating apparatus having the provided structure was obtained. The two wheels that support the airframe during coating here may normally be those with two wheels, but an auxiliary wheel is provided near the paint discharge port so that the wheels do not come into contact with the ground during coating. In addition, a structure in which two wheels are provided at the time of coating is also included, such as a structure that escapes upward.

The bead discharge device includes an outer cylinder having a discharge guide below, and an inner bead case which is rotatably provided in the outer cylinder and has a discharge port, and a handle is connected to the inner cylinder. The bead discharge operation synchronized with the coating application by the opening / closing handle is enabled. Further, the paint tank is composed of a main tank on the machine body and a sub-tank detachably attached to the upper part of the tank.

In this device, the heat source of paint heating is changed from a propane gas cylinder to a lightweight and small cassette-type butane cylinder and its burner, so that the machine can be supported by two simple wheels during coating, resulting in a lighter and smaller overall size. The adaptability of the two-wheel axle to the ground contact surface is large, and the paint discharge port is provided on the rear inner ring side of the two wheels. With three-point support, anyone can draw easily and accurately by construction in the forward direction. And since the paint tank is composed of the main tank on the machine body and the detachable or fixed sub-tank at the top, there is a limit to the drawing application distance when only the main tank is used, while the application distance by the sub tank In addition, by adding a coating material to the sub tank, the drawing application distance is greatly extended while the apparatus is small.

The present inventor has previously proposed a lane marking coating apparatus that is optimal for coating a small lane marking of about several meters according to Patent Document 4. The structure is provided below the machine body consisting of the paint tank and at the paint discharge port of the paint tank, and is provided with one wheel that serves as a fulcrum when drawing and retracts along the construction line, and supports the machine in an inclined or horizontal position. In addition, the present invention is characterized in that a paint tank heating burner and a fuel cylinder holder are provided.

In addition, the wheel of the lane marking coating apparatus conventionally used widely is four wheels as shown in Patent Documents 1 and 2, two wheels with auxiliary wheels as shown in Patent Document 3, and one wheel as shown in Patent Document 4. There are also two wheels and three wheels.

Since the conventional structures described in Patent Documents 1 and 2 use propane gas as a heating source, they have to be equipped with a large volume, high weight, and dangerous substance cylinder. Therefore, since the volume occupied by the propane gas cylinder is large, there is a limit in increasing the volume of the paint tank as viewed from the whole lane marking coating apparatus. Moreover, as a difficulty at the time of use, since it is heavy, it is complicated for an operator to operate and requires skill.

Therefore, conventionally, for the lane lines after the pavement restoration in the construction having the underground work contents such as the pavement industry, the pipe construction business, the electric construction business, and the civil engineering company, the work was ordered from the line construction company. However, the unit price for specialists is high because it is a set of construction work, and there are many cases where immediate construction is impossible, and delivery of the construction was naturally delayed.

Although the lane marking coating apparatus described in Patent Documents 3 and 4 solves the above-mentioned problem, since the boiling point of butane is higher than that of propane, the cassette-type butane cylinder has a low outside air temperature, for example, at 18 ° C. or lower. Since the gas pressure inside the cylinder is lowered due to combustion vaporization, sufficient gas supply is not performed and combustion efficiency is lowered. Therefore, use in winter and cold regions may be restricted.

In view of the above, it is an object to provide an apparatus capable of performing partition line coating using a cassette-type butane cylinder even in an environment where the outside air temperature is low and sufficient gas supply is not performed and combustion efficiency is reduced.

This device has two wheels that support the machine body during coating, and a burner that uses a cassette-type butane cylinder as a heating source below the paint tank that supplies paint to the paint discharge port on the inner side of the two wheels The lane marking coating apparatus was used.
Two auxiliary wheels are provided behind the two wheels that support the machine during coating.

The paint tank is composed of a main tank on the machine body side and a sub-tank that is detachable or fixed to the upper part.

The present invention solves the problems described in paragraphs 0009 to 0012, and anyone can easily apply lane markings with high accuracy and safety, and the combustion temperature is low without sufficient supply of gas due to low outside air temperature. In order to provide a low-priced device using a cassette-type butane bomb, even in an environment where there is a drop in the environment, the above structure is studied and a substantially rectangular parallelepiped shape with an open ceiling surface is provided. A wind-insulating member that is used by pouring a liquid that is hotter than the outside temperature inside to cover the cassette-type butane cylinder, and the combustion temperature is low because the outside temperature is low and gas is not sufficiently supplied. Even in a deteriorating environment, it became possible to perform comparting line coating using a cassette-type butane cylinder.

In addition, a wind and heat insulation member that has a substantially rectangular parallelepiped shape with an opening at the ceiling and the back facing the paint tank and whose height in the height direction is greater than or equal to the height of the butane cylinder is provided so as to cover the periphery of the cassette type butane cylinder. Even in an environment where the temperature is low and the gas supply is not sufficiently performed and the combustion efficiency is lowered, it is possible to perform the division line coating using the cassette type butane cylinder.

In addition, it has a heat conduction plate that transmits the heat of the burner provided below the sub tank to the butane bomb, and by heating the butane bomb, even in an environment where the external temperature is low and gas supply is not sufficiently performed and combustion efficiency decreases, Using a cassette-type butane bomb, it was possible to perform division line coating.

The heat conduction plate referred to here is a plate that gives latent heat necessary for liquid butane to be converted into gas butane gas, and may not necessarily be a plate but may have a rod-like shape.

This device having the above components does not limit the paint discharge port to the rear inner wheel side of the wheel when there are no auxiliary wheels when using one, three, or four wheels instead of two wheels. Including cases.
In addition, in the case of the front push type, the machine body handle is provided behind the paint tank, and on the contrary, in the case of the pulling type where the apparatus of the present invention is drawn and applied by drawing, the machine handle is provided in front of the paint tank.

Since the heat source for heating the paint was changed from propane to a lightweight cassette-type butane cylinder and its burner, the machine body could be supported by simple two wheels during coating, and as a result, the overall weight and size could be reduced. The adaptability of the two-wheel axle to the ground contact surface is large, and the paint discharge port is provided on the rear inner ring side of the two wheels, so the front of the two wheels and the paint discharge port is supported by three points. Anyone can draw easily and accurately by construction in the direction.

Since the paint tank is composed of the main tank on the machine side and the detachable or fixed sub tank on the top, the painting distance for the main tank alone is limited, but the coating distance is extended by the sub tank. In addition, the addition of the paint material to the sub tank allows the line drawing application distance to be greatly extended while being a small device.

The windproof and heat retaining member has a substantially rectangular parallelepiped shape with an open ceiling surface, and is provided with a high temperature liquid poured inside, so that the butane bomb can be warmed and kept warm. Even in an environment where the gas is not sufficiently supplied and the combustion efficiency is lowered, it is possible to perform the division line coating using the cassette type butane cylinder.

In addition, the wind insulation member has a substantially rectangular parallelepiped shape with the ceiling surface and the back facing the paint tank open, and the length in the height direction is more than the height of the butane cylinder and has a locking part, so that the device Can prevent the temperature drop of the butane cylinder by blowing to the air, and can perform lane marking coating using a cassette type butane cylinder even in an environment where the external temperature is low and gas supply is not sufficiently performed and combustion efficiency decreases Made possible.

In addition, it has a heat conduction plate that transmits the heat of the burner provided below the sub tank to the butane bomb, and by heating the butane bomb, even in an environment where the external temperature is low and gas supply is not sufficiently performed and combustion efficiency decreases, Using a cassette-type butane bomb, it was possible to perform division line coating.

In addition, the configuration of the present invention is applicable to the case where the wheel is not one wheel but one wheel, three wheels, or four wheels, there is no auxiliary wheel, and the paint discharge port is not limited to the rear inner wheel side of the wheel. It was possible to expand the range of lane marking coating equipment that can be used.

Since the lane marking coating apparatus of the present invention has a light and simple structure, the price is low and the cost of line drawing coating can be reduced. Anyone can use it and draw an accurate lane marking. In addition, it was light and small, and it was possible to apply the line drawing safely.
Moreover, even in an environment where the outside air temperature is low and the gas supply is not sufficiently performed and the combustion efficiency is lowered, it is possible to perform the division line coating using the cassette type butane cylinder.
