Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soft type gelatin capsule containing a drug and the like and a method for producing the same, and particularly, to optimize the supply state of the inclusion body, product optimization and product specifications. The present invention relates to a novel gelatin capsule, a method for producing the same, and a production apparatus for the same, which can increase the efficiency of the operation and setting work of the apparatus as well as the enrichment of the production.

[0002]

BACKGROUND OF THE INVENTION In manufacturing a soft type gelatin capsule containing a drug or the like, a gelatin sheet having a substantially constant thickness is supplied between a pair of die rolls in a state of worship to wrap the inner package. It is generally manufactured by stitching. At this time, as a drive system of the manufacturing apparatus, for example, a gelatin sheet supply system (hereinafter referred to as a gelatin supply system) for feeding a gelatin sheet having a substantially constant thickness and a suitable viscosity between a pair of die rolls.
And a die roll drive system that drives a pair of die rolls so as to pull in the gelatin sheet, an inner capsule supply system that supplies (injects) the inner capsule contained in the capsule, and the like.

In such a mechanical drive system, power is generally distributed and output from a single main power motor. For example, the gelatin supply system is used as the first system and the die roll drive system is used. When the system is the second system and the inclusion body supply system is the third system, the first to third supply / drive systems are connected by mechanical means, respectively,
Each operation timing, setting, and the like can be finely adjusted. Specifically, it is possible to finely adjust the abutting timing of a pair of die rolls, the gap, the contact pressure of the sheet due to the matching, and the supply timing of the liquid raw material which is generally used as an inner package.

By the way, in such a conventional method, at the actual manufacturing site, so-called setup work until stable and continuous production of gelatin capsules requires a great deal of skill, and a skilled technique is also required. Even if it is a person, it took a lot of time and effort to get the setting out (setup). Explaining the specific setup work, first of all, regarding gelatin, setting the melted gelatin to the optimum thickness and setting it so that it reaches the die roll, and even if the thickness is obtained, the mutual gelatin sheets adhere to each other at the time of supply. There is a demand for a setting that has a certain degree of softness and tackiness, and has a proper shape retention property immediately after the capsule is formed. Further, during or after molding, it is necessary to take out the capsule from the gelatin sheet in a separated state, and for this purpose, the gap and timing of the die roll are required to be set.
Further, the setting of the injection timing of the pump that supplies the inner package needs to be synchronized with the setting of the driving timing of the die roll.

In the conventional method, the following problems are chained due to the above-mentioned driving form. That is, in the conventional method, such setup, for example, when performing fine adjustment of the supply timing of the inclusion body or when exchanging the die roll, it is unavoidable to stop the entire drive system. There was a problem that the situation of the gelatin sheet, which had been set to an appropriate state until then, changed. There is also a problem that it takes a certain amount of time to obtain the optimum setting state of the gelatin sheet before stopping the drive system. Further, in the conventional method, the supply pump for injecting the inner package is generally driven by the plunger, and the shift timing itself is substantially determined by the cam and the eccentric mechanism. Therefore, for example, depending on the location of the same die roll (angular position in the circumferential direction). The supply amount could not be changed appropriately. That is, it has been impossible to produce gelatin capsules with a wide variety of variations by using a pair of die rolls.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of such a background, and it is possible to separately drive a gelatin supply system, a die roll drive system, and an inclusion body supply system, and Development of a new gelatin capsule and its manufacturing method that enables independent adjustment of the die roll drive system and the inclusion system supply system while operating, and can freely select the appropriate supply timing program when supplying the inclusions I tried.

According to the invention described in claim 1, various gelatin capsules can be obtained while using the same die roll. For example, it is relatively easy to obtain, for example, the shape of the capsule outer skin portion, which has almost the same appearance, but the amount of contents and the type of inner envelope body are different.

According to the second aspect of the invention, since the inner envelope is liquid or gel, the supply pressure at this time spreads the gelatin sheet and contributes to the formation of the pocket portion for receiving the inner envelope. Can be expected. Note that the pocket portion is generally formed by suction or the like before the inner package is supplied, but if the inner package is in a liquid or gel state, the suction force or the like required for forming such a pocket portion can be obtained.

According to the invention of claim 8 or 12, for example, the die roll can be replaced or finely adjusted while the apparatus is operating. Further, the setup of the die roll, that is, the alignment setting of the die roll that substantially matches the left and right molding protrusions can be performed very easily. Incidentally, in the past, the main motor of the gelatin supply system was used as the main drive source, and the power was distributed from here by the mechanical transmission means. Therefore, it was impossible to replace the die rolls while the device was operating. Further, the work of aligning the die roll is usually performed by substantially matching the timing marks provided in advance with the inner package nozzle and the die roll, but conventionally, one of the die rolls is aligned by being driven by the main motor. Although it can be done, the other die roll often requires manual adjustment to adjust (positioning) by loosening the bolts etc. that are fitted into the slots from the rear part of the device, which requires time and effort for positioning. It was

As shown in FIG. 8 as an example, the gelatin capsule A is composed of a capsule outer skin portion G made of a gelatin sheet S as a starting material and an inner envelope body N wrapped by the capsule outer skin portion G in a completed state. The capsule outer skin portion G is made of a gelatin sheet S as a starting material, and a pair of these materials are supplied in a facing manner and are fused in a state where they are in close contact with each other. As the inner package N, a material for an appropriate purpose such as a medicine, a nutritional supplement, a health food extract, a seasoning, or a luxury item can be used, and its state (situation) is not only the liquid state as shown in the drawing but also the gel state. A powder, a granular material, or a mixture thereof (for example, a powder-containing suspension in which a powder is mixed with a liquid) can be applied. Incidentally, in the case of applying a liquid one as the inclusion body N, the injection pressure at the time of injecting the liquid may cause the gelatin sheet S to expand secondarily,
An effect of assisting the formation of the pocket portion P that receives the inner package N can be expected.

Next, the gelatin capsule manufacturing apparatus 1 will be described. As shown in FIGS. 1 to 3 as an example, this is composed of a sheet forming part 2 for forming a sheet having a suitable thickness and viscosity while cooling gelatin in a molten state, and a formed gelatin sheet S.

In the capsule molding unit 3, a die roll drive system D3 that drives the pair of die rolls 18 so as to draw in the gelatin sheet S, and in the inner envelope supply unit 4, the inner envelope N to be filled in the capsule is supplied (jetted). In the inner capsule supply system D4 and the capsule unloading section 5, the die roll 18
There is a capsule take-out system D5 or the like that scrapes off the gelatin capsule A that has bitten into the surface with a brush, and conveys the scraped gelatin capsule A by a conveyor. In the present embodiment, these drive systems can be independently driven. I have to. Hereinafter, each molding unit including each drive system will be described.

First, the sheet forming section 2 will be described. This is a part for molding the gelatin sheet S which is the starting material of the capsule outer skin part G, and the two molded gelatin sheets S are supplied to the capsule molding part 3 in a state of worship. As a pair, a pair is provided on the left and right of the frame F with the capsule molding portion 3 interposed therebetween. However, in addition to such a configuration, the sheet forming unit 2 forms the gelatin sheet S by, for example, one sheet forming machine, and cuts the gelatin sheet S into two pieces while the capsule forming unit 3 is reached. In addition, the form etc. which supply to the capsule molding part 3 can be taken.

A gelatin tank (not shown) for storing the melted gelatin is provided behind and above the sheet forming section 2, and the supply hose 10 is pulled out from this gelatin tank. A heater for ensuring a molten state of gelatin is provided in the gelatin tank, and the molten gelatin in the tank is supplied to the spreader box 11 via the supply hose 10. After that, the gelatin is fed to a cooling drum 12 provided below the spreader box 11, and while being cooled to an appropriate temperature, the gelatin is formed into a sheet having an appropriate thickness and viscosity.
Sent to.

The gelatin supply system D2 of the sheet forming section 2 is
This is a drive system for feeding the gelatin sheet S formed as described above to the capsule molding section 3 (between a pair of die rolls), and substantially means mainly driving the cooling drum 12. Moreover, the motor of gelatin supply system D2 is
The drive is distributed from here and is generally transmitted to the servo motor M2 of the die roll 18 or the pump unit 38 of the inner package N, and therefore the motor of the gelatin supply system D2 is called the main motor M. The sheet forming unit 2
The above-mentioned details of the above are omitted here, and the description in Japanese Patent Publication No. 5-88143 (Patent No. 18769776) "Gelatin sheet forming apparatus in gelatin capsule manufacturing apparatus" is incorporated.

The above-mentioned portion serves as the sheet molding portion 2, and thereafter, the capsule molding portion 3 is provided on the side to which the gelatin sheet S is supplied, and both molding portions are relayed. The feed roll 13 is provided so that That is, the gelatin sheet S that has been cooled around the cooling drum 12 is put into the capsule molding unit 3 while passing between the plurality of feed rolls 13 in a zigzag shape. Then, in the vicinity of the feed roll 13, it is possible to provide a thickness sensor for measuring the thickness of the gelatin sheet S put into the capsule molding section 3. The details of this thickness sensor are also omitted here, and the contents described in Japanese Patent Application Laid-Open No. 8-182744 “Device for monitoring thickness of gelatin sheet in gelatin capsule manufacturing device”, which is filed by the present applicant, are incorporated.

Next, the capsule molding section 3 will be described.
As shown in FIGS. 4 and 5, as an example, this structure is mainly composed of a die head 16 including a die roll frame 17 and a pair of die rolls 18. One of the pair of die rolls 18 is fixed and the other is configured to be freely accessible to the fixed die roll 18, and when it is necessary to distinguish between the two,
One is fixed as the fixed die roll 18A and the other is adjusted as the adjustable die roll 18B. In addition, each die roll 18 has
A molding protrusion 19 having an appropriate shape is formed on the surface thereof. For example, when molding a gelatin capsule A having a substantially spindle shape, the molding protrusion 19 having an oval shape with a depressed central portion is formed. To be done. And a pair of die rolls 18
Is to rotate the molding protrusions 19 so that they are substantially aligned with each other so that the gelatin sheets S are abutted (joined) at a proper timing and the periphery of the capsule is sewn.

A suction hole 20 is formed in the inner peripheral portion (bottom portion) of each molding projection 19, and the gelatin sheet S supplied by this suction hole is sucked to form a pocket portion P for receiving the inner package N. Of course, when forming the pocket portion P, it is not always necessary to suck the gelatin sheet S, and for example, the gelatin sheet S is swelled by using the injection pressure of the inner package N, or gelatin before the inner package N is supplied. If the pocket P can be formed by performing embossing or the like on the sheet S, the suction holes 20 do not necessarily have to be provided in the die roll 18. The mechanism for sucking the gelatin sheet S to form the pocket P is also omitted here, and Japanese Patent Application Laid-Open No. H10-211257, entitled "Gelatin Capsules Encapsulating Powder and Granules, and Manufacturing Method Thereof" The description in "the manufacturing apparatus" is incorporated.

Next, the die roll drive system D3 will be described. The die roll 18 is externally fitted to the mounting shaft 21 by an appropriate means such as a key, a spline, a boss and a parallel pin, and as an example, as shown in FIG. Adjustment side die roll 18
The mounting shaft of B is 21B. Also, a pair of die rolls 18
Are configured to rotate in synchronization by gears 22A and 22B meshing with each other. The gear 22A is
While the gear 22B is fixedly attached to the attachment shaft 21A, the other gear 22B is attached to the attachment shaft 21B in a free rotation state. Further, the gear 22A is provided with a gear MG for transmitting the rotational drive from the main motor M on the side opposite to the gear 22B. Also, this gear MG
Is also attached to the motor shaft MS of the men motor M of the gelatin supply system D2 in a free rotation state.

The drive of the die rolls 18 has conventionally been distributed from the main motor M of the gelatin supply system D2 via mechanical transmission means such as gears and links to rotate the pair of die rolls 18. . However,
In such a drive of only the main motor M, the delicate alignment of the left and right die rolls 18, that is, the setting such that the left and right molding protrusions 19 are substantially aligned with each other, which is performed prior to the actual operation, is manually performed with the main motor M It took a very long time to set because it depended on the operation. Further, as a matter of course, conventionally, it was impossible to replace the die roll 18 or set the die roll 18 while operating the sheet forming unit 2 (while continuing to drive the gelatin supply system D2). For this reason, in the present embodiment, as shown in FIG. 6 as an example, the positioning motor M1 that can drive the die roll 18 independently of the main motor M is used.
Is attached to the adjustable die roll 18B.

Due to such a structure, the main motor M side is provided with the main clutch 23 for intermittently connecting, that is, transmitting and interrupting the rotational power of the main motor M to the gear MG. . In addition, the rotational power of the positioning motor M1 side is applied to the adjustable side die roll 1
A positioning clutch 24 is provided on the 8B mounting shaft 21B so as to be intermittently connectable. Furthermore, this mounting shaft 21B
Is provided with a clutch that connects and disconnects the mounting shaft 21B and the gear 22B. When this clutch is connected, the adjustable die roll 18B that rotates together with the mounting shaft 21B is dynamically connected to the stationary die roll 18A via the two gears 22B and 22A and the mounting shaft 21A. This clutch is called a coupling clutch 25. Further, the stationary die roll 18A is provided with a holding brake 26 which is brought into contact with a frame member (die roll frame 17, frame F, etc.) to make the mounting shaft 21A of this one stationary.

A rotary encoder 27 for detecting the rotational position information of the die rolls 18A, 18B is provided on each of the mounting shafts 21A, 21B.
A and 27B) are attached respectively. The rotational position information of the die rolls 18A, 18B detected by the rotary encoders 27A, 27B is used as the internal inclusion supply system D.
4 is transmitted to the pump unit 38 which supplies the inner package N, and is displayed on the monitor 28 attached to the apparatus so that the operator can visually check it. Incidentally, when the rotary encoder 27 divides one rotation (one round) of the die roll 18 into 9000 pulses, that is, 9000 equal divisions, the rotational position information (angle) of the die roll 18 is every 0.04 degrees (360/9000). In addition, the supply status of the inner package N can be appropriately changed according to the rotational position information. The supply status of the inner package N is a general term for the supply amount, supply timing, supply speed, supply pressure, and the like.

A mechanism for adjusting the contact pressure between the left and right die rolls 18A and 18B will be described. The bearing portion 29 of the adjustable die roll 18B is formed so as to be slidable on the other fixed die roll 18A side with respect to the die roll frame 17 as shown in FIGS. Then, a pair of front and rear leaf springs 30 and 31 for pressing act on the bearing portion 29. That is, the pair of leaf springs 30 and 31 are in contact with each other by the central contact portion 32 whose center protrudes, and the leaf spring 30 on the side closer to the bearing portion 29 brings the both ends into contact with the bearing portion 29 so that the bearing portion 29 is not moved. It acts so as to be pushed into the fixed side die roll 18A side.

An adjusting push rod 33 is in contact with both ends of the other leaf spring 31, and the adjusting push rod 33 is configured to be screwed with the die roll frame 17, and its operating end. The adjustment dial 34 is provided on the above, and when the adjustment push rod 33 is screwed tightly, a stronger contact pressure is obtained. It is preferable that this contact pressure be numerically detected and appropriately displayed on the monitor 28.

Further, the capsule molding portion 3 including the pair of die rolls 18 can be provided with a positional deviation detecting mechanism for detecting the occurrence of positional deviation of the die rollers 18 in the circumferential direction. Details of this position shift detection mechanism are also omitted here, and Japanese Patent Application Laid-Open No. 8-182 filed by the present applicant.
The description in No. 743 “Device for monitoring positional deviation of die roll in manufacturing apparatus for gelatin capsule” is incorporated.

Next, the inner package supplying section 4 will be described. This is a gelatin sheet S with pockets P formed.
On the other hand, the inclusion body N such as liquid or powder is supplied (jetted). Incidentally, when the inclusion body N is a liquid,
It is general that the inner envelope body N is jetted (injected) from the time when the pocket portion P starts to be sewn to the time when the suture is completed. However, in the case where the inner package N is a granular material, it is also possible to adopt a mode in which, before the suturing step, the suturing of the pocket portion P is started after being distributed and supplied to the pocket portion P in approximately equal amounts. In the following description, the case where the inclusion body N is a liquid will be described. When a liquid one is applied as the inner package N, the gelatin sheet S expands to fit the inner peripheral surface of the molding projection 19 by the jetting pressure of the liquid, and a secondary effect can be expected. The supply of the body N can assist the formation of the pocket portion P that receives the body N.

As an example, as shown in FIGS. 1 to 3, the inner envelope supply section 4 is provided with a stock solution hopper 37 at the top thereof, and stores the stock solution (inner pack N) therein. A pump unit 38 is provided below the stock solution hopper 37.
This is made up of a large number of plungers combined,
The inner package N is jetted from a plurality of paths at predetermined timing, pressure, etc., and is discharged from the inner package nozzle 40 to the pocket portion P via the delivery pipe 39. The tip of the inner package nozzle 40 is the die roll 1
It is formed in a protruding state so that it can be sufficiently inserted between the eight.

In order to sew the gelatin capsule A (outer periphery) accurately and efficiently, the position of the die head 16 is set so that the left and right molding protrusions 19 on the die roll 18 are substantially aligned with each other, as described above. Is to do. Therefore, the inner package nozzle 40 and the die roll 18
And are provided with timing marks 41 for alignment. Specifically, as shown in FIGS. 5 and 10, in the inner body nozzle 40, a linear timing mark 41 is formed in the vicinity of the constricted tip portion, and in the die roll 18, radiation is applied to the peripheral portion. A plurality of timing marks 41 are formed. And die roll 1
8 is aligned, the die rolls 18 are inched (inching) so that the timing marks 41 are substantially aligned with each other to perform setting (alignment setting). It should be noted that the alignment setting does not always match the timing marks 41 on both sides, but it is actually better to slightly shift the timing marks 41 than to match the timing marks 41 according to the experience of the operator, that is, the experience of the operator. In the die roll 18 in which it is judged that the certain gelatin capsule A is in the sutured state, for example, only the timing mark 41 of one of the die rolls 18 is intentionally shifted by one line in the sheet feeding direction or the returning direction. possible.

Hereinafter, an example of the inclusion body supply system D4 will be described.
It will be described with reference to FIG. In the illustrated embodiment, the delivery pipe 39 in which the inner package N is arranged on the left and right
For the sake of convenience, the route that passes on the right side is route A and the route that passes on the left side is route B.
Route 39B. The inner package supply system D4 stores the inner package N for injection standby, and the inner package N.
2 to the left and right paths, and a slide valve 4 provided between the storage section 42 and the body section 43.
4, and a plunger 45 that reciprocally slides (slides in the left-right direction in the illustrated embodiment) in both paths of the main body 43,
And a plunger holder 46 for holding the plunger 45.

The main body portion 43 is a portion from which the inner package N is alternately sent out to the left and right delivery pipes 39, and a space portion where the plunger 45 slides is formed in the middle of the inner passage, and the A passage 39A side. A space 47A,
The one on the B route 39B side is referred to as a B space 47B. The slide valve 44 also has a function of alternately delivering the inner packet N to the left and right delivery pipes 39 similarly to the main body 43, and the suction port 48 and the discharge port 49 of the inner packet N are A and B. Provided in each route (A route 39A
The suction port is 48A, the discharge port is 49A, the suction port of the B path 39B is 48B, and the discharge port is 49B). And the slide valve 44 is connected to the plunger 45.
With the reciprocating motion of the reciprocating motion, reciprocating sliding in different directions (in the illustrated embodiment, a direction substantially orthogonal to the paper surface) is performed, and in the same path, the suction port 48 or the discharge port 49.
Of these, only one of them acts (communicates). That is, when the inner package N is discharged from the delivery pipe 39 on one path, the inner package N is sucked from the storage section 42 on the other path.

The plunger 45 alternately slides back and forth in both the A and B spaces 47A and 47B of the main body 43 to alternately open and close (open and close) each space. The inner inclusion body N is alternately sent out via the paths 39A and 39B. When the inner package N is pushed out from one space, suction is performed in the other space. The plunger holder 46 holds the plunger 45 and slides the plunger 45 back and forth. When the plunger 45 reciprocates, the rotary motion of the servo motor M2 is converted into a reciprocating motion by a cam or a crank. To do.

The inclusion body supply system D4 is a drive system as described above, and substantially essentially means the servomotor M2. In the present invention, the servomotor M2 can be driven independently of the main motor M of the gelatin supply system D2 and the positioning motor M1 of the die roll drive system D3. Thereby, for example, while operating the apparatus, for example, feeding of the gelatin sheet S and rotation of the die roll 18 are in normal operating states, while finely adjusting the supply timing of the inner package N, or replacing the pump unit 38. It becomes possible to do. Further, the die roll 18 detected by the rotary encoder 27 attached to the mounting shaft 21 of the die roll 18
It is possible to finely adjust the supply status of the inner package N by appropriately setting the operation pattern such as the acceleration / deceleration time, the rotation speed, and the operation timing of the servo motor M2 according to the rotation position information.

The inclusion body supply system D4 is configured as described above, and the supply form of the inclusion body N by this system will be described below in the following two cases. (1) State of FIG. 7A In this state, the suction port 48A of the slide valve 44 communicates with the discharge port 49B of the slide valve 44, and the A space 47A of the plunger 45 opens and the B space 47B closes. It is in a slid state. At this time, the outlet 48B of the slide valve 44 is blocked on the side of the A path 39A, so that the inner package N from the storage portion 42 is blocked.
Is sucked. On the other hand, on the B path 39B side, since the suction port 48B of the slide valve 44 is blocked, normally, the inner package N sucked into the B space 47B is discharged from the discharge port 49B to the delivery pipe 39 (39B).
It is supplied to the pocket portion P through the inner package nozzle 40.

(2) State of FIG. 7 (b) In this state, the discharge port 49A of the slide valve 44 communicates with the suction port 48B, and the A space 47A of the plunger 45 closes and the B space 47B closes. It is slid in the opening direction. At this time, since the suction port 48A of the slide valve 44 is blocked on the A path 39A side, the inner package N sucked in the A space 47A is discharged from the discharge port 49A to the delivery pipe 39 (39A) and the inner package nozzle 40. After that, it is supplied to the pocket portion P. On the other hand, on the B path 39B side, the outlet 49B of the slide valve 44 is blocked, so that the inner package N is sucked from the storage section 42. In this way, the inclusion body supply system D4 alternately injects the inclusion body N from both the A and B paths by alternately repeating the above-mentioned state.

Next, the capsule take-out section 5 for taking out the gelatin capsule A as a finished product below the die roll 18 will be described. Gelatin capsule A after molding
Is often fitted into the molding projection 19 of the die roll 18, so such a gelatin capsule A is scraped off by a scraping brush 52 provided so as to come into contact with the die roll 18, and the gelatin capsule A is scraped off. A pair of forward conveyors 5 provided along the die roll 18
By means of 3, it is conveyed to the front of the device and taken out (see FIGS. 1 and 8). Further, as shown in FIGS. 1 and 3, for example, a blank sheet S ′ after the gelatin capsule A has been punched is sandwiched from both sides between the pair of feed conveyors 53, and the blank sheet S ′ is directly fed downward.
4 (pinching width, adjustable). In consideration of the fact that the gelatin capsule A remains on the blank sheet S ', the free roller 54 can discharge the gelatin capsule A remaining on the blank sheet S'to either one of the pre-feed conveyors 53. Is preferred. In addition, the gelatin capsule A is fed by the advance conveyor 53.
After being conveyed to the front surface of the apparatus by the above, it can be further transferred to another conveyor 55 or the like and conveyed to an appropriate portion.

In this embodiment, the gelatin capsules are taken out by the conveyer in this way. However, this form is not always necessary. For example, as in the conventional case, the gelatin capsules are inclined from the lower side of the die roll to the front side of the apparatus. Gelatin capsule A by the trough (shoot) provided
Of course, it is possible to slide it out and take it out. Further, the capsule take-out system D5 is the die roll 1 as described above.
8 driving of the scraping brush 52 for scraping off the gelatin capsule A that has cut into 8 and the gelatin capsule A scraped off
The capsule take-out system D5 is also a die roll drive system D3.
Similar to the inclusion body supply system D4 and the like, it is preferable that the system can be driven by a system different from other drive systems.

Next, the method of manufacturing the gelatin capsule of the present invention will be described substantially while explaining the operating mode of the apparatus 1 for manufacturing a gelatin capsule having the above-described structure. In the description, a setup method such as initial setting (positioning) of the die roll 18 and a gelatin capsule A that can be manufactured will be described, and a description of an operation mode of the entire apparatus will be omitted (the Japanese Patent Publication No. 5-88143 (Patent No. 187).
No. 6976) is incorporated).

Initial setting of the die roll will be described. (1) Return to origin of rotary encoder First, the origin of the rotary encoder 27 attached to the mounting shaft 21 of the die roll 18 is returned. The rotational position of the mounting shaft 21 of the die roll 18 when viewed from the axial direction is divided by a pulse (for example, 2000 pulses, 9000 pulses, etc.), and the reference position of this pulse is called the Z phase. By aligning the mounting shaft 21 with this Z-phase, the origin return (reset setting) of the rotary encoder 27 attached to the mounting shaft 21 is performed. In the present embodiment, the mounting shaft 21B of the adjustable die roll 18B
Due to the fact that the positioning motor M1 is attached to the
The origin is returned from the mounting shaft 21A of the stationary die roll 18A. Further, such return to origin is performed in a state where the die roll 18 is not fitted to the mounting shaft 21. Further, in the following description, regarding each clutch, a state in which the clutch is connected and power transmission is enabled is turned on, and a state in which each clutch is disengaged and power transmission is disabled is turned off. Further, with respect to the holding brake 26, the locked state in which the brake is applied to make the mounting shaft 21A unrotatable is turned on, and the state in which the lock is released and rotatable is turned off.

(Gear 22A) is fixed. After setting the clutches and brakes in this way, the positioning motor M1 is turned off and the mounting shaft 21A is completely locked, and the rotary encoder 27 attached to the mounting shaft 21A is attached.
The origin return of A is performed.

(C) Locating the origin of the mounting shaft of the adjustable die roll (Z-phase detection) Next, in order to return the mounting shaft 21B to the origin, as shown in FIG. O
N, so that the power of the positioning motor M1 can be transmitted to the mounting shaft 21B. Then, the positioning motor M1 is turned on.
Then, only the mounting shaft 21B of the adjustable die roll 18B is rotated, the Z phase of the mounting shaft 21B is detected, and the origin is set. At this time, since the coupling clutch 25 is OFF, the other mounting shaft 21A does not rotate.

(D) Locking the mounting shaft of the adjustable die roll (returning to the origin) After that, as shown in FIG. 9D as an example, the positioning clutch 24 is turned off, and the positioning motor M1 moves to the mounting shaft 21B. The power transmission of is cut off. Also, the coupling clutch 25 is turned on, and both mounting shafts 21B, 21A
Are dynamically connected. Then, after the setting as described above, the position finding motor M1 is turned off, and in the state where the power transmission from the position finding motor M1 to the mounting shaft 21B is cut off, the origin return of the rotary encoder 27B is performed,
The home return of both mounting shafts 21A and 21B is completed.

(2) Registration of Initial Settings of Die Rolls After that, alignment settings are made so that the molding protrusions 19 of the respective die rolls 18 are substantially aligned, and the aligned die rolls 1 are aligned.
Register 8 positions. Note that the fixed die roll 1 is used here as well.
8A is for performing alignment and setting registration.

(A) In order to carry out registration registration of the fixed die rolls, as an example, as shown in FIG. 10A, each die roll 18 is mounted on each mounting shaft 21, and then the positioning clutch 24 is mounted. Is turned on so that the rotational power of the positioning motor M1 can be transmitted to the mounting shaft 21B. Further, the coupling clutch 25 is turned on to set both the mounting shafts 21B and 21A, that is, the adjustable die roll 18
B, the stationary die roll 18A is in a state of being dynamically connected. Further, the holding brake 26 is turned off, and the mounting shaft 21
A, that is, the stationary die roll 18A is in a rotatable state.

After such setting, the fixed side die roll 18A is inching (inching) by the positioning motor M1 and is aligned with the timing mark 41 of the inner package nozzle 40 as shown in the drawing. 18A is aligned. This alignment position is
It is detected as a pulse value by the rotary encoder 27A and registered by a storage / control unit such as a computer separately. That is, fixed side die roll 18A
Is the origin (Z phase) by the rotary encoder 27A.
From this, it is detected at what pulse the alignment was made,
This position is registered. While the fixed die roll 18A is inching, the adjustable die roll 18B is also inching.

(B) Positioning of Adjustable Side Die Roll Next, in order to register the adjustable side die roll 18B, as shown in FIG.
Is turned on, and the mounting shaft 21A, that is, the fixed side die roll 18A that has already been registered is brought into a fixed state. Further, the coupling clutch 25 is turned off to release the dynamic coupling state of the pair of die rolls 18. Then, after such setting, the adjustable side die roll 18 is moved by the positioning motor M1.
Inching (inching) B, as shown in the figure,
The adjustable die roll 18B is aligned with the timing mark 41 of the inner package nozzle 40. Of course, this alignment position is detected as a pulse value by the rotary encoder 27B, like the fixed die roll 18A,
It is separately registered by a storage / control unit such as a computer. That is, the adjustable die roll 18B is also
The rotary encoder 27B detects at what pulse the position is adjusted from the origin (Z phase), and this position is registered.

(C) Operation preparation state After that, as an example, as shown in FIG. 10 (c), the position determining clutch 24 is turned off and the power transmission from the position determining motor M1 to the mounting shaft 21B is interrupted. Also, the coupling clutch 25 is turned on, and the adjustable die roll 18
B, the stationary die roll 18A is in a state of being dynamically connected. Further, the holding brake 26 is turned off, and the stationary die roll 18A is set in a rotatable state to prepare for operation. Incidentally, the main clutch 23 is turned on during the normal operation of manufacturing the capsule, and the die roll 18 is set to be driven by the power from the main motor M.

When the proper position of the adjustable die roll 18B is registered, the substantial initial setting work of the die roll 18 is completed, and the following operation is performed using the same die roll 18 as described above. No need for initial setting, read registered value (read pulse position)
Thus, the position of the die roll 18 (position setting) can be automatically performed even by an unskilled worker. Incidentally, the initial setting of the die roll 18 in this manner is mainly considering the die rolls already on the market, and when a new die roll is prepared at the same time as the present apparatus, the above-mentioned settings are already set at the time of shipping. If you do, it is not necessarily the required setting.

The rotary encoder 2 is attached to the mounting shaft 21.
7 is attached, and the inner package N can be supplied based on the rotational position information. Therefore, for example, the operation of synchronizing the supply timing of the inner package N with the detection pulse value of the rotary encoder 27 can be performed. Specifically, one revolution of the die roll 18 (mounting shaft 21) is 2000 pulses, and when the molding projections 19 are formed on the die roll 18 at equal intervals, 200 pulses after the first supply, the inner package N To supply.

Next, various forms of the gelatin capsule A which can be produced by the present invention will be described. In the present invention, the rotary encoder 27 allows the die roll 18
It is possible to finely detect the rotational position information of the above, and based on this information, it is possible to control the operation pattern of the servomotor M2 that drives the supply of the inner package N, that is, the acceleration / deceleration time, the rotation speed, the injection (supply) timing, and the like. I am trying. For this reason, it is possible to manufacture the gelatin capsules A with various variations, while using the same die roll 18.

(A) Appearance of a plurality of types This is, for example, as shown in FIG.
The gelatin capsule A has a plurality of appearances such as a heart shape, a spindle shape, and a fan shape (shellfish shape). In this case, for example, the servo motor M2 is not rotated, but is reciprocally rotated (forward / reverse) at a constant angle, that is, before the plunger 45 that reciprocates in the inner-body supply unit D4 reaches the maximum amplitude. By reciprocally moving, the ejection amount of the inner package N can be appropriately changed according to the outer shape of the capsule. Of course, not only the amount (volume) of the inclusion body N but also the inclusion body N itself to be injected can be appropriately changed.

(B) One set multi-capsule This is one in which a plurality of gelatin capsules A filled with an inner package N are connected in a set state by gelatin or the like, as shown in FIG. 11 (b), for example. In the illustrated embodiment, the leaf portions having different clover shapes are formed by separate gelatin capsules A, and each is connected by the gelatin outer skin portion G to form a set state imitating a clover as a whole. In this case as well, in the individual gelatin capsule A, the amount of the inclusion body N or the inclusion body N itself can be appropriately changed.

(C) Same appearance / different content As shown in FIG. 11 (c), for example, this capsule is a gelatin capsule A which has the same appearance as the capsule, but is mainly different in the type of the inclusion body N itself. Is. Note that the heterogeneous content here mainly means that the type (quality) of the inclusion body N is different, but also includes the case where the filling amount is different. By the way, the inclusion body N filled in the capsule
As a method of differentiating the type of the storage unit 42, for example, the storage section 42 in the inclusion body supply system D4 is set to the one for the A path 39A and the storage section 42 for the A path 39A.
Partition for the route 39B and separate inner package N here
Can be stored. Of course, in addition to this, a plurality of pump units 38 can be provided especially when supplying various kinds of inner inclusions N.

Further, in the present embodiment, the inclusion body supply system D4
Since the servo motor M2 of the above can be driven separately from the main motor M, it is supplied, for example, at the injection timing of the inner package N, for example, immediately after the start of suturing the capsule (when the capsule is greatly opened) or immediately before the end of suturing (capsule Can be made while the device is operating. Further, since the positioning motor M1 of the die roll drive system D3 can be driven separately from the main motor M, the die roll 18 can be replaced while operating the apparatus, for example. Further, because the operation pattern of the servo motor M2 can be finely controlled according to the rotational position information of the die roll 18, in order to effectively prevent the liquid dripping of the inner package N at the end of the injection, for example, just before the end of the servo motor M2. To some degree,
It is possible to appropriately suck the inner package N to the inner package nozzle 40 side.

Further, according to the invention of claim 8 or 12, it is possible to perform the work of exchanging the die roll 18 while operating the gelatin supply system D2, which cannot be done conventionally.
In addition, the die roll 1 that substantially matches the left and right molding protrusions 19
The alignment setting of 8 can be performed extremely easily. Further, with respect to the die roll 18 once set, the alignment position can be stored by the pulse value, and from the next time, the visual alignment by the timing mark 41 is not required, and the automatic alignment by the pulse value can be performed.

According to the ninth or thirteenth aspect of the present invention, the normal operation of the die roll 18 for producing the gelatin capsule A is distributively driven by the main motor M,
When the die roll 18 is aligned, a specific structure in which the die roll 18 is independently driven by the positioning motor M1 is possible.
