Abstract

A sealer circulation system according to an exemplary embodiment of the present disclosure includes: a circulation unit; a temperature compensation unit disposed on the circulation line; a supply line branched from the circulation line; a cylinder disposed on the supply line; a coating gun; and an exhaust line connected to an outlet side of the coating gun. The circulation unit is disposed on the circulation line to circulate the sealer. The temperature compensation unit disposed on the circulation line compensates the temperature of the circulating sealer. The cylinder pressure-feeds a predetermined amount of sealer. The coating gun discharges the sealer supplied from the cylinder to the outside by opening and closing a nozzle.

First claim

What is claimed is:

1. A sealer circulation system comprising:
a circulation unit disposed on a circulation line to circulate a sealer;
a temperature compensation unit disposed on the circulation line to compensate a temperature of the circulating sealer;
a supply line branched from the circulation line;
a cylinder disposed on the supply line to pressure-feed a predetermined amount of sealer;
a coating gun that discharges the sealer supplied from the cylinder to the outside by opening and closing a nozzle; and
an exhaust line connected to an outlet side of the coating gun through which any sealer remaining after discharging from the coating gun is exhausted;
wherein the coating gun is provided with a first temperature sensor that senses the temperature of the sealer to be discharged;
wherein the sealer circulation system further comprises a controller that controls the circulation unit, the temperature compensation unit, the cylinder, and the coating gun by using the temperature of the sealer that is sensed by the first temperature sensor, a second temperature sensor, a third temperature sensor, a fourth temperature sensor, a fifth temperature sensor, or a sixth temperature sensor;
wherein a supply valve that controls supply of the sealer is provided at a rear end of the cylinder in the supply line;
wherein a first circulation valve that controls the circulating sealer is provided in a direction in which the sealer flows at a predetermined location where the circulation line branches to the supply line;
wherein a second circulation valve that controls the sealer exhausted from the coating gun is provided in the exhaust line; and
wherein the sealer circulation system further comprises a charging unit that charges the sealer into the circulation line through a charging line that is connected with the circulation line at an intake side of the circulation unit.

2. The sealer circulation system of claim 1 , wherein the second temperature sensor is provided in the cylinder, and wherein the second temperature sensor senses the temperature of the sealer to be pressure-fed.

3. The sealer circulation system of claim 1 , wherein the third temperature sensor is provided at an inlet of the cylinder, wherein the third temperature sensor senses the temperature of the sealer that enters into the cylinder.

4. The sealer circulation system of claim 1 , wherein the fourth temperature sensor is provided at an outlet of the temperature compensation unit, wherein the fourth temperature sensor senses the temperature of sealer discharged from the temperature compensation unit.

5. The sealer circulation system of claim 1 , wherein the fifth temperature sensor is provided at an inlet of the temperature compensation unit, wherein the fifth temperature sensor senses the temperature of sealer that enters into the temperature compensation unit.

6. The sealer circulation system of claim 1 , wherein the sixth temperature sensor is provided in the temperature compensation unit, wherein the sixth temperature sensor senses a temperature of sealer that flows through the inside of the temperature compensation unit.

7. The sealer circulation system of claim 1 , wherein the controller controls the supply valve, the first circulation valve, the second circulation valve, and the charging unit using the temperature of the sealer, sensed by the first temperature sensor, the second temperature sensor, the third temperature sensor, the fourth temperature sensor, the fifth temperature sensor, or the sixth temperature sensor.

8. The sealer circulation system of claim 1 , wherein the temperature compensation unit comprises:
a thermoelectric element provided to apply heat to the circulating sealer or absorb heat from the sealer;
a heat radiation panel provided to absorb heat from the sealer;
a heat radiation fan discharging heat of the heat radiation panel to the outside; and
a cooling block provided adjacent to the thermoelectric element to absorb heat.
