Description

Medicine capsule molding device capable of high speed molding

The present invention relates to a medicine capsule molding apparatus, and more particularly to a medicine capsule molding apparatus that can maintain the sealing quality of the medicine capsule while implementing a high-speed molding of the medicine capsule.

Drug capsules are capsules containing liquid medicine therein. Drug capsules contain the drug in liquid form, so it is important to prevent the medicine inside from leaking to the outside.

Such a capsule manufacturing method has been disclosed in Patent No. 10-0954227 "Fluid supply device, a forming roller and a soft capsule manufacturing device comprising the same".

1 is a schematic diagram schematically showing the configuration of a conventional medicine capsule manufacturing apparatus 10 (20). As shown, the medicine capsule C is formed between a pair of forming drums 11 and 11 'which rotate to face each other, called soft capsule mold dies. The forming drums 11 and 11 'suck the films A and A' supplied to the outer circumferential surface by vacuum adsorption into the forming grooves 11b and 11b 'and the chemical liquid between the pair of films A and A'. The injection part 13 is disposed to simultaneously fill and cut the chemical liquid M, and joining and cutting are performed together.

2 is a schematic diagram schematically showing a cross-sectional structure of a conventional chemical liquid injection unit 13. As shown in the lower portion of the chemical injection portion 13, the chemical liquid discharge holes (13b, 13c) is disposed at a position corresponding to the molding grooves (11b, 11b ') of the molding drum (11, 11'), conventional chemical liquid discharge The balls 13b and 13c were located at a height within 10 mm from the lower end of the chemical injection portion 13. That is, in the conventional medicine capsule manufacturing apparatus, the height h2 of the first chemical liquid discharge hole 13c is positioned at a position lower than 10 mm.

On the other hand, the film (A, A ') used in the manufacture of the medicine capsule is provided by unfolding the gelatin in the form of a sheet, a molding drum after the chemical solution (M) is filled in the gelatin film (A, A') formed in the sheet form When the teeth 11 and 11 'are rotated, the pair of molding drums 11 and 11' come into contact with each other to seal the gelatin films A and A ', thereby manufacturing a medicine capsule. However, the moment the chemical liquid (M) is supplied to the gelatin films (A, A '), the gelatin films (A, A') are temporarily stretched by the chemical solution, which is temporarily increased gelatin films (A, A ') ) Can be stable after the gelatin film (A, A ') is sealed only after the original state is restored. In order to stably seal the medicine capsules, a certain time is required for the gelatin film A and A, which has been temporarily stretched, to be restored to its original state. Accordingly, the forming drums 11 and 11 'of the conventional medicine capsule forming device 10 are therefore required. In the case of 150 mm in diameter, sufficient sealing quality was maintained after a minimum of 0.58 seconds for the film A and A 'to be sealed after the chemical liquid was discharged from the chemical liquid discharge holes 13b and 13c. Therefore, in order to satisfy such a sealing time condition, the conventional capsule forming device 10 has a limitation of driving conditions in which the rotational speed of the forming drums 11 and 11 'must be maintained at 2.0 rpm / min.

That is, the conventional medicine capsulation molding apparatus 10 shown in FIGS. 1 and 2 has a film A after the chemical liquid is discharged from the chemical liquid discharge holes 13b and 13c when the diameter of the molding drums 11 and 11 'is 150 mm. Sufficient sealing quality was maintained by a minimum of 0.58 seconds before, A ') was sealed. In order to satisfy the conditions of the sealing time, and to reduce the noise generated during the chemical injection, the conventional medicine capsule molding apparatus 10 maintains the rotational speed of the molding drum (11, 11 ') of Figure 1 at 2.0 rpm / min, There was a limitation of the driving conditions in which the height h2 of the first chemical liquid discharge hole 13c should be less than 10 mm. As such, in order to increase the rotational speed of the forming drum in order to improve the productivity of the medicine capsule manufacturing, there were constraints to satisfy two conditions that should reduce the adhesion stability of the medicine capsule and the noise generated by the piston during the filling of the medicine liquid. .

Due to the constraints of the driving conditions, the conventional medicine capsule forming apparatus 10 has a limitation in improving the manufacturing efficiency of the medicine capsule since the rotational speed of the molding drums 11 and 11 'is only 2.0 rpm / min.

It may be formed in the same quantity. At this time, the chemical liquid inlet 122 is formed in the shape of a groove, such as a square, semi-circle, ellipse cross section. The cross-sectional shape of the chemical liquid inlet 122 is formed in a groove shape so that the chemical liquid path 124 and the nozzle 123 may be formed at any angle with the contact curved surface 121b formed on both sides from the lower end 121a of the injection unit body 121. ) Is to facilitate the formation. That is, the nozzle 123 is formed at various angles, and the chemical liquid inlet 122 is formed in a groove shape in order to easily form the chemical liquid moving path 124 for connecting the nozzle 123 and the chemical liquid inlet 122. .

The plurality of nozzles 123 are positioned at both contact curved surfaces 121b of the injection unit body 121 to inject a chemical solution into the capsule molding groove 111. In this case, the plurality of nozzles 123 are formed of the forming drums 110 and 110. The center and the lower end portion 121a of the injection unit body 121 may be formed in an angle range of 10 ° to 70 °, preferably 30 ° to 70 ° along the curved surface of the contact curved surface 121b. In addition, when the plurality of nozzles 123 are disposed at different heights along the axial direction of the forming drums 110 and 110 ′ on the contact curved surface 121b, the first nozzle 123 is preferably located at the lowermost end of the contact curved surface 121b.

It is good to form in the range of 22 degrees-70 degrees, More preferably, 40 degrees-70 degrees along the curved surface of the contact curved surface 121b from 121a. For example, the first row nozzle 123a may be formed at a position of 30 ° along the curved surface of the contact curved surface 121b from the center and the lower end 121a of the forming drums 110 and 110 ', and the second row nozzle. 123b may be formed at a position of 35 ° along the curved surface of the contact curved surface 121b from the center and the lower end 121a of the forming drums 110 and 110 '. When the heights of the plurality of nozzles 123 satisfy the above range, high-speed molding of the medicine capsule may be possible while maintaining the sealing quality of the medicine capsule.

Here, the height and angle of the nozzle 123 for the high-speed molding of the medicine capsule molding apparatus 100 of the present invention and the conventional injection drum (11, 11 ') shown in Figs. It may be calculated based on the driving conditions of the unit 13. That is, the height and angle of the nozzle 123 and the rotational speed (V2) of the forming drum (110,110 ') according to the present invention is a film (A) in the conventional molding drum (11, 11') and the chemical injection portion 13 , A ') may be calculated based on the travel time until the film A, A' is sealed.

After filling the chemical liquid from the chemical liquid discharge holes 13b and 13c of the conventional chemical liquid injection part 13 into the films A and A ', the moving time until the sealing of the films A and A' is made as a basic time. By moving the forming drum (110,110 ') at a high speed for the same basic time to calculate the angle and height of the nozzle 123 that can prevent the leakage of the chemical liquid to set the driving conditions of the high-speed molding. That is, in the related art, after injection of the chemical liquid from the low-drug chemical discharge holes 13b and 13c, the molding drums 11 and 11 'move slowly to seal the films A and A', and thus, the medicine capsule of the present invention. The molding apparatus 100 may seal the films A and A 'by rapidly moving the forming drums 110 and 110' after injecting the chemical liquid from a nozzle having a high height.

Conventional and the present invention, the rotational speed of the forming drum (110, 110 ') is different, but the time from injection of the chemical to the suture is set equal to the base time, the leakage of the chemical can be maintained the same.

For example, in order to examine the high-speed molding conditions of the medicine capsule molding apparatus 100 of the present invention having the molding drums 110 and 110 'having a diameter of 150 mm, the driving conditions of the conventional medicine capsule molding apparatus 10 having the same diameter are determined. Review first.

1 and 2, the diameters of the conventional molding drums 11 and 11 'are 150 mm, and the circumferential length of the molding drums 11 and 11' is 471 mm (= 150 mm x 3.14). When rotating at a speed of 2.0 rpm / min and the height h2 of the nozzle 13c is 10 mm, the circumferential movement distance per second of the forming drums 11 and 11 'is circumferential length x rotational speed ÷ 60, and the value accordingly is 15.7. mm / sec (471 x 2.0 ÷ 60). The movement time (base time) from the nozzle 13c to the sealing point is obtained by dividing the height of the nozzle by the circumferential movement distance per second, which is 0.637 sec (10 ÷ 15.7). Based on this, the basic time from filling the chemical liquid in the nozzle 13c to sealing the films A and A 'is set to 0.637 seconds.

The nozzle height required to increase the rotational speed of the forming drums 110 and 110 'from the nozzle 123 to the suture point in the medicine capsule forming apparatus 100 of the present invention based on the above-described basic time is 1.5 times higher than the conventional nozzle height. 15 mm (10 × 1.5) multiplied by 1.5, the nozzle height required to increase the rotational speed of the forming drums 110, 110 'by 1.7 times is 17 mm (10 mm × 1.7).

Here, the circumferential length at an angle of 1 ° is a value obtained by dividing the entire circumferential length by 360. Accordingly, the circumferential length at an angle of 1 ° is 1.3083 mm (471 ÷ 360). A 10 mm high nozzle has an angle of 10 ÷ 1.308 = 7.645 °, a 15 mm height nozzle has a height of 15 ÷ 1.308 = 11.467 °, and a 17 mm high nozzle has an angle of 17 ÷ 1.308 = 12.997 °.

The nozzle height required to increase the speed of the forming drum (110,110 ') to 8 times, that is, 16 rpm / min in the present invention compared to the rotational speed of the conventional molding drum (11, 11') is 2 x 8 = 80 mm The circumferential length of 80 mm is 80 ÷ 1.308 = 61.16 °.

Thus, the nozzle angle for each height of the nozzle 123 for high-speed molding and the anticipated rotational speed and the rotational speed compared with the prior art based on the basic time from the filling of the chemical liquid to the closure of the drug capsule molding device that does not leak the conventional chemical liquid The calculated value of the ratio is shown in FIG.

5 is a cross-sectional view illustrating an example of a height and an angle of the nozzle 123 of the chemical liquid injection part 120. For example, the nozzle 123 may be formed at a position 13 ° along the curved surface of the contact surface 121b from the lower end 121a of the injection unit body 121 at the center C1 of the forming drums 110 and 110 '. The nozzle 123 may be formed at a position of an angle of 30 ° along the curved surface of the contact surface 121b from the lower end 121a of the injection unit body 121 at the center C1 of the forming drums 110 and 110 '. The nozzle 123 may be formed at a position of an angle of 45 ° along the curved surface of the contact surface 121b from the lower end 121a of the injection unit body 121 at the center C1 of the forming drums 110 and 110 '. The nozzle 123 may be formed at a position of 52.5 ° along the curved surface of the contact surface 121b from the lower end 121a of the injection unit body 121 at the center C1 of the forming drums 110 and 110 '. The nozzle 123 may be formed at a position 60 ° along the curved surface of the contact curved surface 121b from the lower end 121a of the injection unit body 121 at the center C1 of the forming drums 110 and 110 '. The nozzle 123 'may be formed at an angle of 7.71 ° similarly to the conventional chemical liquid discharge hole 13c.

Referring to the diagram of FIG. 6, the theoretically formed nozzle 123 at an angle of 13 ° may be sealed of the capsule while achieving a speed increase of 1.7 times or more, and a nozzle formed at an angle of 30 ° ( 123 may be implemented to increase the speed more than three times compared to the conventional, the nozzle 123 formed at a position of 45 ° angle is possible to increase the speed more than five times compared to the conventional, the nozzle 123 formed at a position of 52.5 ° angle is It is possible to increase the speed by more than 6 times compared to the conventional, and the nozzle 123 formed at a position of an angle of 60 ° can be increased by more than 7 times compared to the conventional.

As the angle and height of the nozzle of the chemical liquid injection part 120 are increased, the rotational speed V2 of the forming drums 110 and 110 'is increased to satisfy the basic time. Accordingly, the drum driving unit 130 may drive the rotational speed of the forming drums 110 and 110 'faster as the angle range in which the nozzle 123 is formed from the center of the forming drums 110 and 110' becomes larger.

On the other hand, when the height of the nozzle 123 is set as a result of the theoretical experiment described above, it is not possible to consider the vibration generated when the actual capsule forming apparatus 100 is driven. When the medicine capsule molding apparatus 100 is driven, leakage occurs while the chemical liquid M introduced into the film from the nozzle 123 moves to the sealing position by vibration generated when the molding drums 110 and 110 'are rotated at high speed. Can be. Accordingly, there is a limit to unlimitedly increasing the rotational speed of the forming drum (110, 110 '). As a result of experiments in the case of injecting the chemical liquid into the nozzle 123 of various heights shown in Figure 6 when the nozzle angle (α) exceeds 70 °, leakage of the chemical liquid (M) is generated that the sealing quality is deteriorated Could know.

Therefore, the angle of the nozzle 123 for the high-speed molding of the medicine capsule is a conventional height of 10mm, the angle is 7.645 °, compared with the conditions that rotated at 2 rpm / min, the nozzle angle is 10 ° ~ 70 °, preferably It is preferable to set in the range of 30 degrees-70 degrees. If the nozzle angle is lower than 10 °, the difference between the rotational speed of the conventional molding drum is insignificant, and if the nozzle angle exceeds 70 °, the leakage of chemical liquid is generated due to the vibration generated by the rotation of the molding drum. Problems of deterioration of quality may occur.

The chemical liquid injection unit 120 includes a plurality of nozzles having one height in a row along the axial direction of the forming drums 110 and 110 ', or two nozzles having different heights as shown in FIG.

The chemical liquid nozzle 227 is included.

The injection part main body 221 is formed in the upper surface is flat, the lower portion is formed recessed to correspond to the circumferential surface of the forming drum (210, 210 ') symmetrically around the insertion end 222, forming drum (210, 210') and the drum It includes a film contact surface 226 is in contact with the film. A plurality of chemical liquid nozzles 227 are disposed on the film contact curved surface 226.

The plurality of chemical liquid nozzles 227 are formed on the film contact curved surface 226 at intervals corresponding to the arrangement intervals of the capsule forming grooves 211 along the axial direction of the forming drums 210 and 210 '. In this case, the plurality of chemical liquid nozzles 227 may be arranged in one row or at different heights on the film contact curved surface 226 along the axial direction of the forming drums 210 and 210 ', and may be arranged in different heights. ) Are arranged at different heights, the chemical nozzles 227 of different heights may be arranged in two or more rows, and three, four, five, six, seven, eight, nine, etc. It may be arranged together, and may be arranged in more than 10 rows. Preferably, it is preferably arranged in two rows, four rows, six rows, eight rows, and the like.

As illustrated in FIG. 11, the plurality of chemical liquid nozzles 227 are formed to be spaced apart from the lower end of the insertion end 222 by the nozzle angle α along the curved surface of the film contacting surface 226. Here, the nozzle angle α is formed in the range of 12 ° to 175 °.

Here, the nozzle angle α of the chemical liquid nozzle 227 for high-speed molding of the medicine capsule molding apparatus 200 of the present invention is a conventional forming drum (21, 21 ') shown in Figure 7 and 8 having the same diameter And the driving condition of the chemical liquid injection unit 23 is calculated. That is, the nozzle angle α of the chemical liquid nozzle 227 and the rotational speed V2 of the molding drums 210 and 210 'according to the present invention shown in FIG. 14 are conventional molding drums 21 and 21' and the chemical liquid injection unit ( In 23), the chemical liquid is calculated based on the movement time from filling the films A and A 'to sealing the films A and A'.

In FIG. 8 (a), the movement time from the chemical liquid discharge nozzle 23b of the conventional chemical liquid injection part 23 to the films A and A 'is filled and then the film A and A' is sealed. By the time, the nozzle angle α of the chemical liquid nozzle 227 which can prevent the leakage of the chemical liquid by moving the forming drums 210 and 210 'at high speed during the same basic time is calculated and set as the driving condition of the high-speed molding. .

That is, in the related art, after injection of the chemical liquid from the low-liquid chemical discharge nozzle 23b, the molding drums 21 and 21 'move slowly to seal the films A and A', whereas the medicine capsule molding apparatus of the present invention is used. A nozzle 200 is formed by the chemical liquid nozzle 227 from a position where the films A and A 'are sealed, that is, a region where the pair of molding drums 210 and 210' contact each other (X in FIG. 9). Placed apart by as much as possible, a pair of forming drum (210, 210 ') at a high speed to seal the film (A, A').

The conventional molding drums 21 and 21 'of FIG. 7 and the present invention have different rotational speeds of the molding drums 210 and 210', but the time from injection of the chemical to the suture is set equal to the basic time, so that the medicine capsule C The sealing quality of can be maintained. For example, in order to examine the high-speed molding conditions of the medicine capsule molding apparatus 200 of the present invention having the molding drums 210 and 210 'having a diameter of 150 mm, the driving conditions of the conventional medicine capsule molding apparatus 20 having the same diameter are determined. Review first.

As shown in FIGS. 7 and 8, when the forming drums 21 and 21 ′ are rotated at a speed of 2.0 rpm / min, the diameters of the conventional forming drums 21 and 21 ′ are 150 mm and the forming drums 21 are 21. The circumferential length of, 21 ') is 471mm (= 150mm * 3.14), and the circumferential length of 1 ° is 471 ÷ 360 = 1.308mm. The height h2 of the chemical liquid discharge nozzle 23b is 10 mm, and moves from the chemical liquid discharge nozzle 23b to the region where the forming drums 21 and 21 'come into contact with each other and the films A and A' are sealed. Height h3 = 7.36 mm. The circumferential angle α2 of the forming drums 210 and 210 'from the chemical liquid discharge nozzle 23b to the drum contact area is 7.36 ÷ 1.308 mm = 5.626 °, and the angle α1 of the height h2 of the chemical liquid discharge nozzle 23b. Is 10 mm ÷ 1.308 mm = 7.645 °. Therefore, after the chemical liquid M is injected into the films A and A 'from the nozzle 23b, the total distance h4 required to be sealed in the contacting region is 10 mm + 7.36 mm = 17.36 mm, and the total angle (alpha) 3 is 7.645 degrees + 5.626 degrees = 13.271 degrees. Accordingly, if the angle from the chemical liquid ejecting nozzle 23b to the film A and A 'to be sealed is set to approximately 5.63 °, the driving speed V2 of the molding drums 210 and 210' is set. The nozzle angle α required to improve 1.3 times is 13.27 ° x 1.3-5.63 ° = 11.62 °, and the nozzle angle α required to improve 1.5 times is 13.27 ° x 1.5-5.63 ° = 14.275 °. In the same way, the nozzle angle α required to increase the driving speed V2 by 10 times is 13.27 ° x 10-5.63 ° = 127.07 °.

FIG. 15 is a diagram showing a nozzle angle for increasing the rotational speed of the forming drums 210 and 210 'of the present invention based on the basic rotational speed 2 rpm shown in FIG.

As shown in FIG. 15, the medicine capsule molding apparatus 200 according to the present invention changes the position of the chemical liquid nozzle 227 away from the closed position X to increase the driving speed of the molding drums 210 and 210 'by 10 times. The above can be improved. Referring to the diagram of FIG. 15, the chemical liquid nozzle 227 formed at an angle of 12 ° may seal the medicine capsule while increasing the speed by approximately 1.3 times or more, and the chemical liquid nozzle formed at the angle of 60 ° ( 227 may implement a speed increase of approximately 5 times in the prior art, and the chemical liquid nozzle 227 formed at a position of 100 ° may be 8 times faster than the conventional liquid chemical nozzle 227 formed at a position of 160 °. ) Can be increased by more than 12 times compared to the conventional, and the chemical liquid nozzle 227 formed at an angle of 175 ° can be increased by more than 13 times compared to the conventional. As the nozzle angle α of the chemical liquid nozzle 227 of the chemical liquid injection unit 220 is increased, the rotational speed V2 of the forming drums 210 and 210 'is increased to satisfy the basic time. Accordingly, the drum driving unit 230 may drive the rotational speed of the forming drums 210 and 210 'faster as the angular range in which the chemical liquid nozzle 227 is formed from the center of the forming drums 210 and 210' becomes larger.

Here, when the nozzle angle α is formed smaller than 12 °, the difference between the rotational speed of the conventional drum and the molding drum is insignificant. When the nozzle angle α exceeds 175 °, the molding drum as shown in FIG. 210, 210 ') because the curvature of the rotation is reduced to a wider place, so that the liquid injected into the capsule molding groove 211 flows to the outside. Therefore, the nozzle angle α of the chemical liquid nozzle 227 is preferably formed in the range of 12 ° to 175 °.

On the other hand, the chemical liquid injection unit 220 is provided with a plurality of chemical liquid nozzles in a row along the axial direction of the forming drum (210, 210 ') to one height, or nozzles having different heights are provided side by side in two rows At the same time, the chemical liquid can be injected into the capsule forming grooves 211 at different positions, and nozzles having different heights are arranged in three rows, four rows, five rows, six rows, seven rows, eight rows, nine rows, and even ten. It may also be provided in rows or more. According to the present invention, as the rotational speed of the forming drums 210 and 210 'is increased, the chemical nozzles of different heights can increase the injection speed of the chemical liquid to simultaneously inject the chemical liquid into the capsule forming grooves 211 at different positions.

In addition, when the plurality of chemical liquid nozzles 227 are disposed at different heights on the film contact curved surface 226 along the axial direction of the forming drums 210 and 210 ', the film contact curved surfaces 226 at the insertion end 222. The first nozzle is located in the range of 12 ° to 175 °, preferably in the range of 30 ° to 175 ° along the curved surface of the film contacting surface 226 from the center of the forming drums 210 and 210 'and the insertion end 222. The second nozzle located above the first nozzle is preferably in the range of 17 ° to 175 ° along the curved surface of the film contact surface 226 from the center of the forming drums 210 and 210 'and the insertion end 222. Is preferably formed in the range of 35 ° to 175 °, and the third nozzle located at the top of the second nozzle has a curved surface of the film contact surface 226 from the center of the forming drums 210 and 210 'and the insertion end 222. Therefore, it is preferably formed in the range of 22 ° to 175 °, preferably in the range of 40 ° to 175 °. At this time, the height of the first nozzle, the second nozzle, the third nozzle, etc. are set in consideration of the difference by the position of the capsule forming groove 211, the height is preferably set to a difference of about 5 ° on average It is good. Meanwhile, the height of the nozzle 127 and the nozzle angle α may be adjusted differently according to the diameters of the forming drums 210 and 210 '.

9 to 11 is a medicine capsule molding apparatus 200 according to a preferred embodiment of the present invention is that the nozzle angle (α) is set to 170 °, referring to Figure 15, the conventional medicine capsule molding of Figure 7 The forming drums 210, 210 ′ can be driven 13 times or more faster than the device 20.

9 and 14, as the nozzle angle α increases, the width W2 from the center of the chemical injection portion 220 to both sides increases. In the conventional chemical liquid injection unit 23 of FIG. 8, since the nozzle 23b is positioned at the center area, the width W1 of the chemical liquid injection unit 23 does not need to be wide. On the other hand, since the chemical liquid injection unit 220 according to the preferred embodiment of the present invention has to be located at the nozzle angle of 170 °, the chemical liquid nozzle 227 is disposed, and the injection unit main body 221 has a pair of molding drums ( 210, 210 ') to cover the entire upper portion. That is, the width (2 × W2) of the chemical liquid injection unit 220 may be formed larger as the nozzle angle (α) is larger, preferably the width (2 × W2) of the chemical liquid injection unit 220 is It can be formed larger than the diameter of the forming drum.

11 is a view showing the configuration of a chemical injection unit 220 according to a preferred embodiment of the present invention. FIG. 11 is a view illustrating a case in which one row of chemical liquid nozzles 227 are disposed on both sides of the chemical liquid injection unit 220.

As illustrated in FIG. 11A, a plurality of chemical injection paths 223 are formed along the axial direction of the forming drums 210 and 210 ′ on the upper surface of the chemical injection unit 220. The chemical liquid injection path 223 guides the chemical liquid M supplied from the chemical liquid supply part 240 to the chemical liquid vertical movement path 225. The chemical liquid M moved along the chemical liquid vertical movement path 225 is discharged into the capsule molding groove 211 through the chemical liquid nozzle 227.

Here, the chemical liquid nozzles 227 are arranged in one row on the film contact curved surface 226 as shown in FIG. The capsule forming grooves 211 formed in the forming drums 210 and 210 'are arranged in a zigzag form in which neighboring rows alternate with each other.

The chemical liquid nozzles 227 arranged in one row alternately inject the chemical liquid M into the capsule molding groove 211a of the preceding row and the capsule molding groove 211b of the rear row.

12 is a view showing the shape of the chemical liquid injection part 220a when the chemical liquid nozzles 227 are arranged in four rows from side to side.

As shown in (a) of FIG. 12, a pair of chemical injection paths 223a are disposed on the upper surface of the injection unit body 221a of the chemical injection unit 220a, and a pair of chemical injection paths 223a are fixed. The interval d1 is disposed to be spaced apart. The separation interval of the chemical injection path 223a corresponds to the interval d1 between the adjacent chemical liquid nozzles 227 as shown in FIG.

A pair of chemical liquid injection passages 223a are respectively formed with a pair of chemical liquid vertical movement passages 225a, and four chemical liquid nozzles 227a, 227b, 227c, and 227d are coupled to the chemical liquid vertical movement passages 225a.

The chemical liquid nozzle 227a of the first row injects the chemical liquid M into the capsule molding groove 211a of the first row, and the chemical liquid nozzle 227b of the second row of the chemical liquid M into the capsule molding groove 211b of the second row. The chemical liquid nozzle 227c in the third row is injected into the capsule molding groove 211c in the third row, and the chemical liquid nozzle 227d in the fourth row is injected into the capsule molding groove 211d in the fourth row. Spray the chemical liquid (M).

The four rows of chemical nozzles 227a, 227b, 227c, and 227d simultaneously spray the chemical liquid into the four rows of capsule molding grooves 211a, 211b, 211c, and 211d, and then rotate to the next capsule molding groove by rotation of the molding drums 210 and 210 '. Spray the chemical solution.

Accordingly, the number of driving of the cam and the piston to drive the chemical liquid to the chemical liquid injecting path 223 is reduced to 1/4 when compared to when the chemical liquid is injected one row at a time.

FIG. 13 is a view showing the shape of the chemical liquid injection part 220b when the chemical liquid nozzles 227 are arranged in eight rows from side to side.

In the upper portion of the injection part body 221b of the chemical injection portion 220b, a set of four chemical injection holes 223b is formed. A chemical liquid vertical movement path 225b is formed at an end of each chemical liquid injection path 223b. The four chemical liquid vertical movement paths 225b are spaced apart from each other in the horizontal direction by a predetermined distance d2 and d3, and are spaced vertically apart by a predetermined height L so that no interference occurs in the injection of the chemical liquid. .

In addition, the end portion of the chemical liquid vertical movement path 225b is connected to two rows of chemical liquid nozzles as shown in FIG. As a result, eight chemical liquid nozzles 227a, 227b, 227c, 227d, 227e, 227f, 227g, and 227h are formed in the four chemical liquid vertical movement paths 225b.

A total of eight rows of chemical nozzles (227a, 227b, 227c, 227d, 227e, 227f, 227g, 227h) are formed on the film contact curved surface 226b as shown in FIG. 211a, 211b, 211c, 211d, 211e, 211f, 211g, 211h).

Accordingly, the number of driving cycles of the cam and the piston for driving the chemical liquid to the chemical liquid injection path 223 is reduced to 1/8 as compared with the case of spraying the chemical liquid by one row.

In the medicine capsule forming apparatus 200 according to the present invention, the driving speed of the molding drums 210 and 210 'is increased by changing the position of the chemical liquid nozzle 227. As a result, the noise and vibration of the cam and the piston are increased by the driving of the chemical liquid supply unit, while the chemical liquid nozzles 227 are formed in two rows, three rows, four rows, five rows, six rows, seven rows, and eight rows. Since the number of driving of the cam and piston is reduced compared with the conventional first row, the total driving noise is the same as that of the conventional 2 rpm.

For example, when the chemical liquid is filled at the same nozzle angle, the noise generated when rotating 6 by 1 column charge is 12 turns by 2 heat charges, when rotates 24 by 4 heat charges, and rotates 36 by 6 heat charges. In this case, it may be the same as the case of 48 revolutions with 8 thermal charges.

As shown in FIG. 15, in order to increase the driving speed of the forming drums 210 and 210 'according to the state in which the forming drums 21 and 21' are driven at 2 rpm of FIG. It needs to be adjusted.

In other words, to increase the multiplication by three times, the nozzle angle should be adjusted to 34.18 °. At this time, considering the driving noise, it is possible to calculate the number of heat of the chemical liquid nozzle 227 optimized for the increase drainage.

That is, even if the chemical liquid nozzle 227 is in a single row up to an increase of 1 to 3 times, it is possible to maintain a low noise while maintaining a stable sealing quality, and when the chemical liquid nozzle 227 is in two rows up to an increase of 4 to 6, the sealing quality is stable. And low noise can be maintained, and a stable sealing quality can be maintained when the chemical liquid nozzle 227 is in four rows up to an increased drainage of 7 to 12, and 13 to 14 times stable sealing when the chemical liquid nozzle 227 is in six rows. Quality can be maintained.

On the other hand, depending on whether the chemical liquid is a powder mixture or an oil component, the number of the chemical liquid nozzles 227 according to an increase and multiple of the driving speed may vary.

An operation process of the medicine capsule forming apparatus 200 according to the present invention having such a configuration will be described with reference to FIGS. 9 to 11.

A pair of molding drums 210 and 210 'are provided to rotate to face each other, and a chemical injection portion 220 is disposed on the pair of molding drums 210 and 210'. Here, the chemical injection portion 220 is formed to cover all of the upper portion of the pair of forming drums (210, 210 '), the chemical nozzles (227,227a) along the curved surface of the contact surface around the insertion end of the nozzle angle (α) It is formed in one row at 170 °.

On the surfaces of the pair of forming drums 210 and 210 ', a pair of films A and A' are rotated, respectively.

When the chemical liquid supply unit 240 supplies the chemical liquid M to the chemical liquid injection path 223, the chemical liquid M is moved to the chemical liquid nozzle 227 through the chemical liquid vertical movement path 225. The chemical liquid nozzle 227 injects the chemical liquid M into the capsule molding groove 211 as shown in FIG. 11C.

The drum driving unit 230 is a chemical liquid (M) is injected from the chemical liquid nozzle 227 in a basic time until the sealing position (X) in which the capsule forming grooves 211 of the pair of molding drums 210 and 210 'contact each other. The driving speed V2 of the forming drums 210 and 210 'is adjusted to be moved.

In the closed position, the cutting protrusions 213 of the pair of capsule forming grooves 211 are engaged with each other, and the pair of films A and A 'are cut and the medicine capsules are formed to lower the pair of forming drums 210 and 210'. To fall.

When the nozzle angle α is 170 °, referring to FIG. 15, the driving speed V2 of the forming drums 210 and 210 ′ may be adjusted to about 26 rpm / min.

When the driving speed (V2) of the forming drums 210 and 210 'is 26 rpm / min, the sealing speed of the capsule is about the same as that of the conventional nozzle angle of 7.645 ° and 2 rpm / min, although the driving speed is 13 times faster. Can be maintained. Accordingly, the manufacturing efficiency of the medicine capsules C formed in the same forming drums 210 and 210 'may be 13 times faster while maintaining the same sealing quality.

Here, in consideration of the noise generated by the faster driving of the forming drums 210 and 210 ', when the chemical liquid nozzles 227 are formed in six to eight rows, the sealing quality as well as the driving noise can be reduced.

As described above, the medicine capsule molding apparatus according to the present invention separates the angle of the nozzle for injecting the chemical liquid away from the sewing position, thereby improving the driving speed of the molding drum and maintaining the sealing quality of the medicine capsule while maintaining the quality of the medicine capsule. High speed molding can be realized. In addition, the thermal water of the chemical liquid nozzle can be adjusted in various ways. In particular, the driving noise may be controlled by increasing the number of heat of the chemical liquid nozzle to reduce the number of times the chemical liquid supply unit is driven to supply the chemical liquid.
