Figure 3 schematically shows an ink storage tank 1120 and an ink supply unit 1110 according to an embodiment of the present invention.

The ink supply unit 1110 according to an embodiment of the present invention includes an ink supply tank 1111 that accommodates ink in an internal space and discharges the ink through a first pipe (a) connected to one surface; an ink supply pump (1112) connected to one side of the first pipe (a) and discharging the ink contained in the inner space of the ink supply tank (1111) to the second pipe (b); It includes a viscosity sensor unit in the internal space, and the second pipe (b) is connected to one side to accommodate the ink discharged from the ink supply pump 1112 in the internal space, and measures the viscosity of the ink by the viscosity sensor unit. an intermediate chamber (1113) that controls the viscosity of the solvent and then discharges the ink to the third pipe (c) connected to the other side; and a solvent supply unit 1114 that accommodates the solvent in the internal space and supplies the solvent to the intermediate chamber 1113 through a fourth pipe (d) connected to one surface.

In other words, with this configuration, the ink can exert the effect of not containing substances harmful to the human body and the environment.

However, since ethanol evaporates more easily than the organic hazardous substances, there is a problem in that it is difficult to control the viscosity of the ink under process conditions. In order to solve this problem, the packaging material manufacturing system 1 according to an embodiment of the present invention includes a configuration capable of measuring the viscosity of the ink in real time and additionally supplying a solvent based on the measured value. Accordingly, the packaging material manufacturing system 1 can exert the effect of easily controlling the viscosity of the ink.

More specifically, in one embodiment of the present invention, the ink supply tank 1111 can accommodate ink in its internal space. The ink contained in the inner space of the ink supply tank 1111 flows into the ink supply pump 1112 through the first pipe (a) by the suction and discharge force of the ink supply pump 1112 and then flows into the second pipe ( It can be accommodated in the inner space of the intermediate chamber 1113 through b).

A viscosity sensor unit 1113-1 may be disposed in the internal space of the intermediate chamber 1113, and the viscosity sensor unit 1113-1 detects ink flowing into the internal space of the intermediate chamber 1113 at regular time intervals. The viscosity can be measured and the measured value can be transmitted to the viscosity control unit 1115.

The viscosity control unit 1115 can determine whether to perform the process of adding a solvent by comparing the measured value measured by the viscosity sensor unit 1113-1 with a preset viscosity target value (V). .

At this time, the process of adding the solvent may be performed by the solvent supply unit 1114. To this end, the solvent supply unit 1114 may include a solvent chamber (not shown) that accommodates the solvent in an internal space.

In one embodiment of the present invention, the viscosity of the ink introduced into the inner space of the intermediate chamber 1113 by the viscosity control unit 1115 is lower than or equal to the preset target value (V). In this case, the process of adding solvent by the solvent supply unit 1114 is not performed. That is, the ink flowing into the inner space of the intermediate chamber 1113 can be supplied to the ink storage tank 1120 through the third pipe (c) without adding a solvent.

Since the viscosity of the ethanol-based ink according to an embodiment of the present invention increases simply by stirring under process conditions, the viscosity of the ink flowing into the inner space of the intermediate chamber 1113 is lower than the preset target value (V). In the same case, removal of solvent may not be necessary.

On the other hand, in one embodiment of the present invention, when the viscosity control unit 1115 determines that the viscosity of the ink flowing into the inner space of the intermediate chamber 1113 is higher than the preset target value (V), the solvent supply unit 1114 ) The process of adding a solvent is performed. At this time, a solvent is added and mixed with the ink flowing into the inner space of the intermediate chamber 1113, and as a result, the viscosity of the ink contained in the inner space of the intermediate chamber 1113 is lowered to form ink with a controlled viscosity. Thereafter, the ink whose viscosity is controlled can be supplied to the ink storage tank 1120 through the third pipe (c).

With this configuration, the ink supply tank 1111 according to an embodiment of the present invention can automatically supply ink with controlled viscosity to the ink storage tank 1120.

Meanwhile, the ink supply unit 1110 according to an embodiment of the present invention may include a fifth pipe (e) connected to the ink storage tank 1120. Ink contained in the inner space of the ink storage tank 1120 can move toward the ink supply tank 1111 of the ink supply unit 1110 through the fifth pipe (e).

With this configuration, the ink contained inside the ink supply tank 1111 can be continuously agitated.

That is, the ink supply tank 1111 of the present invention can maintain the viscosity of the ink already supplied to the ink storage tank 1120 at a constant level and continuously stir the ink, thereby improving the quality of the ink. . That is, the ink supply tank 1111 can play a role in improving the quality of the final packaging material of the packaging material manufacturing system 1 of the present invention by improving the viscosity and quality of the ink.

Figure 4 exemplarily shows viscosity and solvent input amount over time in one embodiment of the present invention.

Figure 4(a) shows real-time viscosity measured values over time according to an embodiment of the present invention, and Figure 4(b) shows the solvent input amount over time according to an embodiment of the present invention.

As described above, viscosity can be measured at preset time intervals, and Figures 4(a) and 4(b) exemplarily show a situation where the viscosity is measured at an arbitrary time interval t. At this time, t = t ₁ = t ₂ - t ₁ .

As shown in FIG. 4, if the viscosity measurement value measured by the viscosity sensor unit at any time t ₁ is determined to be higher than the target value (V) preset by the viscosity control unit 1115, the solvent supply unit 1114 ) can perform a solvent addition process.

Meanwhile, as shown in FIG. 4, when it is determined that the viscosity measurement value measured by the viscosity sensor unit at any time t ₂ is equal to or lower than the target value (V) preset by the viscosity control unit 1115, the solvent The supply unit 1114 may stop the solvent addition process.

That is, with this configuration, the ink supply unit 1110 can control the concentration of the ink by measuring the viscosity of the ink and automatically supplying the solvent, thereby improving the quality of printing of the final packaging material.
