Abstract

PURPOSE:To quantitatively supply an adhesive aid regardless of the viscosity of the adhesive aid and the change in the diameter of a pipe, by providing a quantitative gear pump comprising an abrasion resistant and impact resistant material on the way of a supply pipe to supply the adhesive aid to a coating leading end. CONSTITUTION:The adhesive aid W in a storage tank 1 is supplied to the coating leading end part 7 of a brush equipped with a change-over valve 6 through a supply pipe 5. In this case, because a quantitative gear pump 8 comprising SUS, ceramic or hard nylon is provided on the way of the supply pipe 5, in supplying the adhesive aid W under pressure, said adhesive aid W can be always supplied to the coating leading end part 7 in a quantitative amount even if conditions such as the viscosity of the adhesive aid W, the change in the diameter of the pipe or solidification are changed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an adhesion aid application system, and more specifically, an adhesion aid application system in which the adhesion aid is applied to the member to be coated by force-feeding the adhesion aid in fixed amounts to the application tip. The present invention relates to an adhesion aid application system.

[Prior art]

Conventionally, when installing a windshield on a car body,
In order to improve the appearance of the adhesive part of the windshield, it is common practice to apply a black baking print to the outer periphery of the windshield in advance, and then apply an adhesion aid (primer) and adhesive to this outer periphery before installation. be.

By the way, when applying the adhesion aid to the outer periphery of the window glass, it is possible to use, for example, a brush, brush, gauze, etc., but when applying with these,
In order to ensure automation, application appearance, and appropriate coating film thickness, it is necessary to use pressure-feeding that does not pulsate and always has constant quantitative properties even when conditions such as the viscosity of the adhesion agent, changes in pipe diameter, and adhesion change. is necessary.

As the above-mentioned pressure feeding method, conventionally known methods include a pressurization method, a roller pump method in which a tube is squeezed with a roller, a cylinder pump method (Japanese Patent Application Laid-Open No. 59-96072), a micro pump method, and a diaphragm pump method. However, in the case of such conventional pressure feeding methods, there were problems such as changes in the discharge amount due to liquid viscosity, pulsation, sticking, wear, etc., making it difficult to constantly pump the liquid with a constant quantitative quality. .

[Purpose of the invention]

This invention was devised by focusing on the conventional problems, and its purpose is to adjust the conditions such as the viscosity of the adhesive agent, changes in pipe diameter, fixation, etc. when the adhesive agent is being pressure-fed. Even if the liquid changes, it is possible to always supply a quantitative amount of liquid to the dispensing tip, automatic dispensing can be performed according to the application, and it is durable enough for industrial use. The present invention provides an adhesion auxiliary agent application system that can perform the following steps.

[Structure of the invention]

In order to achieve the above-mentioned purpose, this device pumps the adhesion aid in the storage tank into the application tip in fixed quantities through a fixed-rate gear pump made of wear-resistant and impact-resistant material installed in the supply pipe. The gist of the method is to apply it to a member to be coated.

[Embodiments of the invention]

The present invention will be described in detail below based on the accompanying drawings.

The attached drawing shows a schematic configuration diagram showing an application system for an adhesion aid W (brimer), in which 1 is a storage tank for the adhesion aid W, and the adhesion aid W is automatically applied to the storage tank 1. It is equipped with a detector 2 for detecting the remaining amount of adhesion auxiliary agent W that is required when the adhesion auxiliary agent W is used, and a stirrer 3 for ensuring the uniformity of the adhesion auxiliary agent W. A dry air ventilation pipe 4 is inserted to prevent this from happening.

The adhesion auxiliary agent W contained in the storage tank 1 is supplied via a supply pipe 5 to an applicator tip 7 of a brush or the like equipped with a switching valve 6.
A fixed-rate gear pump 8 made of wear-resistant and impact-resistant material (for example, SUS, ceramic, hard nylon, etc.) is provided. This gear pump 8 uses a stainless steel gear type which has non-pulsating quantitative performance and is durable in order to ensure a uniform coating appearance and a constant coating thickness.

Note that the coating tip 7 has a coating shape.

A material having different functions is used depending on the application purpose, but it is also possible to use a known material. Further, 9 is a shelter tank for preventing the coating tip 7 from sticking, and is kept there during the suspension of coating, and 10 is a tank for preventing the coating tip 7 from sticking.
A flow meter, a pressure gauge, a temperature sensor, etc. are installed in the middle of the flow meter, and constantly detect the state of the adhesion auxiliary agent W being pumped.

Note that the remaining amount detector 2 may be an external measuring device, and the switching pulp 6 may be installed outside the supply pipe 5. Furthermore, the material of the application tip 7 such as a brush is not particularly limited as long as it can follow the shape of the application surface.

In this invention, as described above, a metering type gear pump 8 is provided in the middle of the supply pipe 5, and the adhesion auxiliary agent W is applied to the application tip 7.
Therefore, when pressure-feeding the adhesion aid W, even if the conditions such as the viscosity of the adhesion aid W, changes in pipe diameter, adhesion, etc. change, a constant amount of liquid is always supplied to the application tip. 7.

〔Effect of the invention〕

This invention, as described above, pumps the adhesion auxiliary agent in the storage tank to the application tip in fixed quantities via a fixed-rate gear pump made of wear-resistant and impact-resistant material provided on the supply pipe, Since the adhesive is applied to the member being coated, even when conditions such as the viscosity of the adhesive agent, changes in pipe diameter, and adhesion change when the adhesion agent is pumped, a quantifiable amount of liquid is always delivered to the application tip. For example, it is possible to perform automatic coating according to the application, such as the thickness and curvature of the coating layer, and it is durable, so it has the effect of being able to be used sufficiently for industrial use.
