ODF manufacturing system and method for strip coating and front coating using slot die

The present invention relates to a system and method for manufacturing ODF for line-shaped coating and front coating using a slot die, and more particularly, when discharging an undiluted solution of an oral dissolving film (ODF), tilting rotation and linear reciprocating movement of the slot die The process is removed so that the dispensing of the undiluted solution is continuously discharged without stopping, and after the drying process, the cutting process is performed to cut the dried undiluted solution in the longitudinal direction, thereby enabling operation without movement and rotation of the slot die. Manufacture of ODF for stripe-shaped coating and front coating that can keep the discharge pressure uniformly, maximize the production compared to the same manufacturing time, and reduce the defect rate by increasing the precision and uniformity of the thickness and area of the discharged stock solution It relates to systems and methods.

Oral dissolving film (ODF) is a film that is put into the oral cavity, such as the tongue, oral mucosa, and sublingual, and dissolved in the oral cavity. As it is manufactured as a product, its use is increasing due to the advantages of not only excellent portability and mobility, but also fast absorption through the oral mucosa, reduced breakage compared to capsules and tablets, and ease of administration.

In particular, in recent years, with the development of quality of life and the sharp increase in interest in health, food for various purposes such as nutritional supplements, health supplements, medicines, and erectile dysfunction drugs are being taken, but these multi-purpose foods are mainly capsules and tablets. voluntary administration is easy, but the non-voluntary administration process is complicated as well as easy to break. As a way to solve these shortcomings, various studies to manufacture multi-purpose foods into oral dissolving film (ODF) is in progress

1 is a block diagram showing an oral dissolution film manufacturing apparatus disclosed in Korean Patent Registration No. 10-1980283 (Title of the invention: slot die coater and oral dissolution film manufacturing apparatus having the same).

1, the oral dissolution film manufacturing apparatus (hereinafter referred to as the prior art) 100 is a slot die (slot die) 121 in which a slot 122 is formed so that the coating solution is applied to the base film 102, and the coating solution The tanks 152 that are stored, and pumps 151 that pressurize the coating solution so that the coating solution is discharged through the slot 122 through the inside of the slot die 121 from the tanks 152, and the slot A tilting servo motor 185 providing power for tilting the die 121 about a rotation axis parallel to the width direction of the base film 102, and the slot die 121 to the base film A linear motion servo motor 161 that provides power to linearly move in the direction approaching 102 and in the opposite direction, and a dryer that dries the coating solution 103 applied to the base film 102 to form an oral dissolution film It consists of a packaging machine 192 for individually packaging the oral dissolution film formed by passing through the 191 and the dryer 191.

In the prior art 100 configured as described above, the tilting of the slot die 121 and the linear motion of the base film 102 and the opposite direction are respectively, the tilting servo motor 185 and the linear motion servo motor 161 ), the spacing between the lines of the coating solution on the base film 102 is maintained constant with high precision, and an unintentional drop of the coating solution does not occur between lines.

However, looking at the operation process of the slot die 121 of the prior art 100, the slot die 121 is a first moving step of linearly moving in the direction toward the base film, and the slot die moved through the first moving step ( 121) a discharging step of discharging the coating solution through the slot 122, a discharging stop step of stopping the discharging of the coating solution, a tilting rotation step of tilting and rotating the slot die 121, and a tilted rotating slot die 121 It consists of a first rotation step of horizontally moving in a direction opposite to the base film 102, and since this step is repeated for each coating solution discharging process in each row, the coating solution discharge is not continuously performed, but every cycle (T). As a result, the coating solution discharging process time is excessively small compared to the total process time, and thus the production is significantly reduced.

In addition, in the prior art 100, a tilting servo motor 185 for tilting and rotating the slot die 121, a linear motion servo motor 161 for horizontally reciprocating the slot die 121, and their accessories are essential Since it must be provided, not only the design is complicated, but there are also frequent failures due to the complicated design, so that the production process is stopped due to equipment inspection and replacement infrequently.

In general, the coating solution has viscosity and cohesive force as it contains starch, but the viscosity and cohesive force have a characteristic in that when the discharge pressure and position are changed, a slight deviation of the discharge mass occurs.

However, the prior art 100 does not take these characteristics of the coating liquid into account at all, and when the discharge of the coating liquid is stopped and then discharged, the thickness or area of the discharged coating liquid is different due to the change in viscosity and cohesive force compared to the same conditions. This phenomenon occurs, and accordingly, the uniformity of the coating solution discharged to the base film 102 is deteriorated.

2 is a perspective view of a plate-shaped ODF manufacturing facility disclosed in Korean Patent Registration No. 10-1851223 (Title of the Invention: Plate-shaped ODF manufacturing equipment and its manufacturing method).

As shown in FIG. 2, the plate-shaped ODF manufacturing facility (hereinafter referred to as the second prior art) 200 of FIG. 2 includes a raw material supply cylinder 201, a coater 202, a coating conveyor 203, and a drying unit ( 204 ), a cutting unit 205 , and a packaging unit 206 .

The raw material supply cylinder 201 accommodates a liquid raw material therein, and is connected to the coating machine 102 by a hose having a valve installed therein.

The coating machine 202 receives the liquid raw material from the raw material supply barrel 201 , and discharges the liquid raw material to the coating conveyor 203 .

At this time, the coater 202 is configured such that the discharge ports (not shown) are formed to be spaced apart from each other at regular intervals in the width direction.

The drying unit 204 dries the liquid raw material on the coating conveyor 203 to form a gel.

The cutting unit 205 cuts the liquid raw material gelled by the drying unit 104 to a predetermined size.

The packaging unit 206 packages the liquid raw material cut to a predetermined size by the cutting unit 205 .

Since the second prior art 200 continuously injects the liquid raw material into the coating conveyor 203 in a state in which the coater 202 is fixed, a larger amount of the oral dissolution film ( ODF) can be produced.

In general, the liquid raw material of ODF has high surface tension due to its viscosity and cohesive force, as well as being supplied to the inner space of the long-width coating machine 202 through a single hose. Accordingly, the liquid raw material accommodated in the coating machine 202 is mainly agglomerated (agglomerated) in the area adjacent to the hose by its own viscosity, cohesive force, and surface tension, and as it is spaced outward from the area adjacent to the hose, the capacity or mass deviation occurs. has

In order to solve this problem, a certain amount of time must elapse in the state of being accommodated. However, due to the nature of the operation in which the internally received raw material is discharged and the raw material is continuously introduced from the outside, the ejector is ejected in a non-uniformly distributed state, so it depends on the position of the width. It has different discharge pressures, and thus has a structural limit in that the mass deviation in the width direction of the raw material coated on the base film increases.

That is, in the second prior art 200, since the liquid raw material accommodated in the coating machine 202 is not uniformly distributed in the receiving space, that is, it is discharged in an aggregated state by surface tension, the width direction of the liquid raw material coated on the base film Due to the severe mass deviation of the product, it is difficult to produce a product with a uniform thickness, and there are problems that manufacturing precision and product completeness are poor.

In other words, in the second prior art 200, the coating machine 202 is formed to have a long width, so that the raw materials are aggregated and concentrated in the inner space of the area adjacent to the hose, so that the discharge pressure and the discharge mass are not uniform depending on the position of the width. It has a disadvantage that it is difficult to produce a product.

In addition, in the second prior art 200, since the liquid raw material discharged by the coating machine 202 extends in the longitudinal direction to the base film, and is coated in a line shape spaced apart from each other in the width direction, the coater 202 is formed as a single discharge port. Compared with the case of being coated over the entire surface, it has the disadvantage of lowering the production compared to the same process time.

The present invention is to solve this problem, and the solution of the present invention is to configure the slot die so that the discharging process of the undiluted film is continuously performed without stopping, without tilting rotation and horizontal reciprocating motion, and at the same time discharging to the base film The film undiluted solution to be used is configured to be formed of multiple rows of strip-shaped coating bodies that are spaced apart in the width direction but extend in the longitudinal direction, thereby significantly increasing the coating solution discharging process time compared to the overall process time to maximize production, as well as To provide an ODF manufacturing system and method that can improve the discharge amount, thickness, uniformity, and uniformity of the discharged film stock solution by maintaining the viscosity and cohesive force of the film stock solution accommodated in the slot die as the position is fixed.

It is to provide an ODF manufacturing system and method that can be

In addition, another solution to the present invention is to selectively lower some of the sliding shields according to the control of the operator, and to determine the quantity, width and thickness of the slots of the slot die by the lowered sliding shields, so that the dispersion diaphragm, etc. It is to provide an ODF manufacturing system and method that can manufacture oral-dissolving films of various widths and thicknesses without replacing parts, reduce installation costs, and maximize process efficiency.
