The present invention relates to an automatic environment compensation capsule manufacturing apparatus with improved concentricity and strength of the capsule, and more particularly, in a portion where the capsule is molded, the transfer fluid is heated to maintain the temperature of the film to improve the concentricity, and to improve the concentricity of the capsule. In the part where the film is hardened, the strength can be improved by rapidly cooling, and the filling material supply unit, which has a decisive effect on the production of capsules based on the detected production speed and quality, detects the production speed and quality of the manufactured capsule, and controls the speed of the interrupter. It relates to an automatic environmental compensation capsule manufacturing apparatus with improved concentricity and strength of capsules that can improve quality by controlling.

BACKGROUND ART Capsules containing various medicines, foods, favorites, etc. are easily ingested and are now widely used. Among them, as a capsule containing a liquid filling, a seamless capsule is widely used because of high productivity and the like.

The seamless capsules are embedded in various types of products (such as filters or air fresheners of cigarettes) or used as seamless capsules alone (medicines or cosmetics, etc.) After this, the film melts and the liquid inside flows out.

As a method of manufacturing a seamless capsule, the liquid filling material is discharged from the central nozzle of multiple nozzles, and the liquid coating material is discharged from the annular nozzle surrounding the central nozzle, cut into small pieces and dropped into the cooling liquid (hardening liquid). The method is conventionally known. In this method, the dropped droplets are spherical in the cooling liquid and stabilized in the spherical shape by the gelation of the coating material.

As a manufacturing apparatus for a seamless capsule, Korean Patent Publication No. 10-1250087 discloses a method and apparatus for manufacturing a non-spherical seamless capsule.

The above technology relates to a technology for manufacturing a spherical seamless capsule and compression molding the manufactured spherical seamless capsule into a non-spherical shape.

In addition, a method for manufacturing a seamless capsule and an apparatus for manufacturing a seamless capsule using the same are disclosed in Korean Patent Publication No. 10-1905101.

The technology is made of a vortex forming means for forming a spiral vortex by rotating the fluid in one direction in a transfer tube that sequentially transfers a plurality of capsules by flowing the fluid in the capsule forming unit, and a conductive metal material surrounding the outer wall of the transfer tube. It is characterized in that it includes an antistatic means for preventing the generation of static electricity.

The above techniques include a double nozzle composed of an inner nozzle from which a filling material is ejected and an outer nozzle from which a coating material is ejected, and a conveying pipe in which the filling material and the coating material ejected from the double nozzle are encapsulated and freely falling. , the double tube is exposed to the outside, and there is a disadvantage in that the viscosity of the coating material is sensitively changed according to the external temperature.

That is, the viscosity of the film material of the capsule moving inside the transfer pipe is formed differently depending on the external environment (temperature, etc.). Accordingly, in the configuration in which the transfer pipe is exposed to the outside, even if the same film material is used, the transfer speed of the transfer fluid and the ejection rate of the material (filling material and film material) ejected from the nozzle are instantaneously controlled according to the change in the viscosity of the film material. and at the same time, there is a problem in that the temperature of the conveying fluid must also be precisely controlled.

In addition, by detecting the shape and production speed of the capsule passing through the transfer pipe to control the pumping amount of the filling material and the coating material, a configuration for improving the production of the capsule and manufacturing a high-quality seamless capsule is required.

On the other hand, the ejection port side of the nozzle 400 is immersed in the conveying fluid, the coating material and the filling material is ejected, and the ejected coating material is wrapped around the outside of the filling material by the conveying fluid. In this process, the temperature of the supplied conveying fluid is maintained within the set temperature range, but since the temperature of the filling material and the coating material ejected from the nozzle 400 is relatively higher than the temperature of the supplied conveying fluid, the temperature of the conveying fluid is will rise That is, the appropriate temperature of the conveying fluid is in the range of 10 ~ 18 ℃, the filling material and the film material and the appropriate temperature is in the range of 60 ~ 100 ℃.

According to this, the temperature of the conveying fluid is increased by the temperature of the filling material and the coating material ejected from the nozzle 400 in the upper part of the conveying pipe 450, and the temperature of the conveying fluid is discharged from the conveying pipe 450. is gradually increased until

However, since the temperature of the filling material and the coating material (hereinafter referred to as 'core material') is relatively higher than the temperature of the conveying fluid, when the high temperature core material comes into contact with the relatively low temperature conveying fluid, the inside of the core structure As the temperature of the filling material located in the spheroid is rapidly lowered, the time margin for spheroidization is short. Accordingly, the concentricity of the filling material is reduced.

In addition, as the film material comes into contact with the transfer fluid at a relatively low temperature, the roundness is lowered, and as the temperature of the transfer fluid gradually rises as it progresses toward the lower side of the transfer pipe, the film material is not cured. There is a problem that can be discharged from the transfer pipe in the state.

In addition, since the transfer pipe 450 is exposed to the external environment, the internal temperature of the transfer pipe 450 is affected depending on the external temperature. to drive within the range of

In addition, the temperature of the transfer fluid in the upper region of the transfer pipe 450 at the initial stage when the capsule of the core structure is formed by being ejected from the nozzle 400 should be relatively higher than the transfer fluid temperature in the lower region. That is, the outer temperature of the upper region of the transfer pipe 450 must be relatively higher than the temperature of the transfer fluid to improve the concentricity of the filling material and the roundness of the coating material, and the lower region of the transfer tube 450 is The outside temperature should be relatively lower than the temperature of the conveying fluid to harden the coating material and improve the strength.

The upper region of the transfer pipe 450 may improve the concentricity of the capsule ejected from the nozzle 400 only when the temperature of the transfer fluid is raised. However, the temperature of the first fluid supplied to the first fluid circulation housing 720 is lowered by dissipating heat by the transfer fluid therein. will be introduced into Accordingly, a first fluid temperature maintaining device 740 for maintaining the first fluid at an appropriate temperature is configured in the first fluid storage tank 710 .

Here, the appropriate temperature of the first fluid should be relatively higher than the temperature of the transfer fluid. Preferably, the appropriate temperature of the first fluid may be made in the range of 30 ~ 60 ℃.

If the appropriate temperature of the first fluid is less than 30 ℃, it is difficult to expect an effect of increasing the temperature of the transported fluid, and if it exceeds 60 ℃, the temperature of the transported fluid is also increased, so that the gelation of the coating material is delayed and the roundness is reduced. There are possible drawbacks.

4, the second fluid circulation unit 800 serves to maintain the lower outer region of the transfer pipe 450 at a second temperature, and the second fluid in which the second fluid is accommodated. It is configured to include a storage tank 810 , a second fluid circulation housing 820 , a second fluid circulation pump 830 , and a second fluid temperature maintaining device 840 .

The second fluid is circulated inside the second fluid circulation housing 820 , and the circulated second fluid is received back into the second storage tank 810 through the discharge passage.

In the upper region of the transfer pipe 450 , the strength of the coating material ejected from the nozzle 400 can be improved only when the temperature of the transfer fluid is lowered. However, the temperature of the second fluid supplied to the second fluid circulation housing 820 is increased by absorbing heat by the transfer fluid therein, and the second fluid of the elevated temperature is transferred to the second fluid storage tank 810 ) is introduced into Accordingly, a second fluid temperature maintaining device 840 for maintaining the second fluid at an appropriate temperature is configured in the second fluid storage tank 810 .

Here, the appropriate temperature of the second fluid should be relatively lower than the temperature of the transfer fluid. Preferably, an appropriate temperature of the second fluid may be in the range of 4 to 10°C. At this time, when the appropriate temperature of the second fluid is less than 4 ℃, the cost required to maintain the temperature is increased compared to improving the strength of the capsule, and effectiveness is reduced.

However, in order to prevent heat conduction between the first fluid circulation housing 720 and the second fluid circulation housing 820, a separate or spaced structure is preferable, and more preferably, the first fluid circulation housing 720 and the second A heat conduction prevention pad 750 for preventing heat conduction may be installed between the fluid circulation housings 820 .

Here, heat is emitted while the supplied first fluid circulates inside the first fluid circulation housing 720 , and heat is absorbed while the supplied second fluid circulates inside the second fluid circulation housing 820 . is made

Accordingly, in the first fluid circulation housing 720 and the second fluid circulation housing 820, the density is different according to heat release and absorption of the fluid.

The laser module 920 detects the number of capsules falling through the transfer pipe 450, and includes a laser emitting unit 921 that emits laser light in a specific wavelength band, and a laser emitted from the laser emitting unit 921. and a sensor unit 922 for receiving light.

At this time, the sensor unit 922 may be a CMOS (Complementary Metal-Oxide Semiconductor) or CCD (Charge Coupled Device) line sensor may be applied. A sensor that can do this is sufficient.

According to the above configuration, the sensor unit 922 receives the laser light emitted from the laser emitting unit 921. When the capsule passes between the laser emitting unit 921 and the sensor unit 922, The laser emitting unit 921 is temporarily unable to receive the laser light. Accordingly, the sensor unit 922 outputs an output signal whenever the laser light is not received.

The control module 930 determines whether the concentricity is suitable or not based on the image transmitted from the vision module 910, and based on the output signal transmitted from the laser module 920, the number of capsules produced per second (or per minute). The number is calculated and controlled to be displayed on the display module 940 .

In addition, the control unit 930 outputs a vibration period control signal for controlling the vibration period to the interrupter 300 (refer to FIG. 1 ) based on the determination result on the concentricity and the number of capsules produced per second (or per minute).

According to the present invention, in the capsule molding process in which the coating material ejected from the nozzle surrounds the filling material to form droplets, the time the coating material wraps the filling material as the temperature around the transfer pipe is maintained at a predetermined temperature at the time the capsule is molded Since the time for the filling material to be located in the center is secured, and the filling material can be positioned in the center of the capsule, there is an advantage that the filling material of the manufactured capsule can improve the concentricity.

In addition, there is an advantage in that the strength of the coating material can be maintained at an appropriate level by quickly curing the coating material by maintaining the ambient temperature of the transfer pipe at a temperature suitable for curing in the section where the coating material is cured.

In addition, there is an advantage in that the quality of the capsules produced can be optimally maintained by monitoring the production speed and concentricity at which the capsules are manufactured.
