Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to guiding capsules with caps and unequal vertical postures from a capsule feeder to the capsule inlet/outlet of the drum when the capsule inlet/outlet of the drum reaches the uppermost position. Using a capsule rollover device with an iron groove in the capsule body provided on the upper and lower surfaces of the drum, the capsule with its cap facing downward moves 1800 turns from the top of the drum to the bottom of the drum while remaining upright in the entrance/exit hole. Without adjusting the above regulations, the caps will be supplied to the next process with their caps facing upwards, which is suitable for drug injection.Only capsules with caps facing upwards will have their bodies iron-inserted into the body loading grooves and placed in the drum. The base of the regulating claw that is rolled over in the elongated hole for overturning the capsule and goes in and out of the capsule entrance/exit hole is rotatably supported on an eccentric pin of a small disk fixed to the planetary gear, and A regulating claw that passes through a long hole for overturning the capsule is accommodated, and is slidably supported by a guide pin fixed to a cup that rotates with the planetary gear, and the movement of the regulating claw is determined from the cycloidal curve movement drawn by the eccentric pin. The drum is converted into a linear motion in the radial direction, and only the capsules that have been transferred to the sideways rotation at the bottom of the drum are moved so that the cap is on the upper side (center of the drum).
The present invention relates to a method and apparatus for adjusting the posture of a capsule, which adjusts the posture so as to face the capsule and then converts and supplies the capsule to a posture suitable for filling drugs, etc. in the next step.

Conventionally, a method and device for adjusting the direction of this type of capsule were disclosed in Japanese Patent Publication No. 53-12 filed by the applicant of the present invention.
No. 24, but in the disclosed invention, the capsule extrusion regulation pawl that moves in and out first slides along a groove inside the rotating drum, and is attached to the other end of the pawl. A fixed ball bearing moves in the groove of a fixed cam, and the pawl slides along the curved surface of the cam groove as the drum rotates.

However, in order to adjust the direction of the capsule at high speed, it is necessary to supply oil to the sliding surfaces of the claws that come into contact with the capsule and to the cam grooves. It is impossible to lubricate these types of devices.Therefore, it is impossible to increase the sliding speed of these sliding surfaces without lubrication, and it is impossible to increase the speed beyond a certain level with the device disclosed in the above publication. Secondly, in the device disclosed in the above, in order to overturn the body of the capsule, the body violently collides with a stationary regulation piece, and the body must be rotated at a speed exceeding a certain degree. In this case, the degree of impact exceeds the limit and causes problems such as damage to the capsule, and this type of device has the disadvantage that it cannot satisfy the desire to further increase the speed at night. Thirdly, capsules that are supplied in a mixed manner become heavier when capped.
Statistically, 65% of postures with the cap on the bottom side and 35% of postures with the cap on the top side are 0 degrees.
It is difficult to select only those capsules with caps on the upper side suitable for filling drugs and supply them to the next process from among such mixed capsules. Therefore, in the device disclosed in this disclosure, all caps are subject to regulation indiscriminately, regardless of whether the cap is on the upper side or the cap on the lower side, which has the drawback of being irrational and wasteful. In addition, special public service No. 53-1
No. 223y will also be disclosed, but the invention relates to a means for printing on the side surface of a capsule, and the field of the invention is fundamentally different from a means for filling drugs, etc., and it also involves the use of full force to overturn the capsule. However, it does not provide a rational means to distinguish between those with the cap on the upper side and those with the cap on the lower side, and to apply regulation only to those in one of the positions, and ultimately There is no effect of supplying the cap to the next process in an upright position on the upper side, and all the caps are simply turned over, and there is no effect of changing the position to a position suitable for drug filling. In particular, since a unique means called airflow is used to correct the rollover, the structure is complicated, the operation is not stable, and there are practical drawbacks. However, the present invention has a completely different perspective from these inventions.
Capsules in a messy position are first sorted into two types: those with caps on the top and those with caps on the bottom.
The capsule introduction side and the discharge side to the next process are transferred by turning 180 degrees, and a relatively large number of capsules with the cap on the bottom side are excluded from the regulation, and a relatively small number of capsules with the cap on the top side are transferred. Bring the chisel into contact with the rotating body and roll it over,
It is rational that a relatively large number of capsules are fed to the next process without being adjusted, and the adjustment claws are inserted into the grooves inside the drum. By eliminating the conventional structure in which the capsule slides along the shaft, high-speed rotation is possible without the need for lubrication, and by rotating it sideways using a rotating body, it prevents the regulating claw from colliding with the capsule. We have succeeded in achieving high efficiency, which is the lifeblood of this type of device, by enabling high-speed rotation, and because we have divided the capsule attitude control drum in the radial direction, we can simplify the processing and assembly of the device itself. The assembly time can be significantly shortened, the handling is easier with fewer operational troubles, and even female workers can maintain it.

Now, to explain in detail the attached drawings showing an example of the implementation of the present invention, 1 is a posture regulating drum, and as shown in FIG. Two rows of capsule inlet/outlet holes 2, 2 through which capsules can enter and exit are bored through the ring of the drum 1, and in this embodiment, the circumference is divided into 18 equal parts (
20 degrees apart), and 18 capsule entrance/exit holes 2 were provided in a row.

Since the number of divisions is easy, it is advantageous for processing.
Errors are also small, and therefore accuracy can be maintained sufficiently. In addition, in order to facilitate processing and assembly, a ring-shaped drum 1
is divided into two in the radial direction. As shown in Figures 2 and 3, 3 is the entrance chamfer of each capsule entrance/exit hole 2;
is a groove for posture adjustment, which is slightly narrower than the capsule cap, and has a diameter equal to the diameter of the capsule entrance/exit hole 2;
The capsule inlet/outlet hole 2 is connected to a long hole 5 for overturning the capsule, which is bored as a pair with the capsule inlet/outlet hole 2.
-'6 is a drum mounting hole provided on the side of the drum as shown in FIG. It is detachably fixed to the tip of the drum mounting member 8 which is provided with a saddle. Here, drum 1 is divided into two parts, and drum 1 is
The reason why the drum mounting hole 6 was drilled on the side is that capsules generally come in sizes according to standards from size 0 to size 5, and the size is selected depending on the drug to be filled. In addition, it is necessary to prepare a large number of drums for each standard size of capsule, and to replace them according to the standard size of the capsule. 8. As shown in Fig. 4, 7a is a capsule with the cap on the upper side among the capsules 7 that are sent in a mess from the capsule feeder, and 7b is a capsule with the cap on the lower side. It is a capsule that has become.

When feeding capsules, since the capsule side is relatively heavy, there is a natural tendency for the cap side to be at the bottom.
Statistically, the latter reaches 65%, and the present invention attempts to correct the posture of only the capsule 7a whose cap is on the upper side, which accounts for 35% of the former. 18 is drum 1
A capsule rollover device fixedly installed along the upper and lower surfaces.
As shown in FIG. 4, body iron grooves 9, 9 are bored in the upper surface of the body so that they can pass through the body of the forceless bushel 7.

The body side grooves 9, 9 have rollers 12 (
A rotating body) is rotatably supported. In this way, in the capsule transfer device, the capsule 7b with the cap of more than half of the full power capsule is on the lower side, even if it is introduced into the capsule entrance/exit hole 2, the cap has a larger diameter than the inside of the groove 9.
Without reaching the body iron groove 9 of the capsule overturning device 10, the drum was kept in an inverted position with the cap facing down, and as the drum gradually stopped rotating, the lateral position of the drum took on a horizontal direction. Furthermore, at the discharge point at the lower end, the position is changed to 180 degrees, and the cap is inserted upward into the holes 15, 15 bored on the circumference of the disk 14, which rotates in synchronization with the drum 1 installed below the drum, as shown in FIG. In this position, 65% of the capsules 7b can be supplied to the next process for drug filling without any need for direction adjustment, etc., and can be supplied to the next process for drug filling, as shown in Figure 4. The capsule 7a falls with its body into the body drilling groove 9 of the capsule rolling device 10, and a roller 12 (rotating body) is rotatably supported by a shaft 11 at the end of the drum rotation direction in the groove 09. The capsule collides with the body, changes its posture into a rollover state, and rolls over into the elongated capsule rollover hole 5 with the cap facing forward.
13 is a guide that allows the capsule 7a to fully roll over,
This is also to prevent the capsule 7a from falling out of the long hole 5 for overturning the capsule.

That is, when the drum 1 rotates, the capsule rolls over as described above and is held in the capsule rollover slot 5, and the guide 13
is necessary only in the direction in which the capsule is about to fall; ``In Figure 2, below the line 900, the direction of the capsule falling changes to the outer circumference of the drum, so in the upper half it moves inward, and in the lower half it moves inwards. It is necessary for the outside (not shown).It is an inner ring installed on the inner periphery of the drum mounting part 8, and 19 is a fixed scale 2 whose base end is fixed to the fixed part turtle 6. This cup is installed so that it can be rotated freely via a bearing 2 hook, 21, and a cup rotating gear 22 that meshes with the internal gear hook 8 is fixed to the outer periphery of one end of the cup hook 9. 23 is a drive. This gear is fixed to the tip of the drive shaft 24 rotatably supported on the fixed member 16, and is adjacent to the cup rotation gear 22.

The drive gear 23 is rotated by external power and drives the internal gear chain 8 via the cup rotation gear 22. 25 is a fixed ball 2Q' inside the cup door 9.
These fixed stationary gears are four planetary gears that mesh with the stationary gear 25, which is provided by dividing the inner surface of the 26G cup into four equal parts, and a small circular plate 27 with two eccentric pins is installed at the tip. The rotary shaft 29 is fixed to the base end of the rotary shaft 29 so that it can be rotated freely.

3. The base of the skin is fixed to the eccentric pin 28 with four regulating claws that can be rotated freely, and the tip part is bifurcated so that it penetrates and enters and exits the capsule entrance and exit holes 2, 2 provided in two rows on the drum. It is branched into.

31 is the largest hole bored in the middle part of each regulating claw 30;
Reference numeral 2 designates a guide pin fitted into the outer periphery of the cup 16, with a guide pin 32 passing through the elongated hole 31, and a regulating claw 3.
The movement of the river mast is regulated by the eccentric pin 28 and the guide pin 32, and it moves in a trajectory as shown in FIG.

Furthermore, FIG. 7 illustrates a mode in which a capsule 7a, which is rolling and rotating in the capsule overturning elongated hole 5, is made to stand upright in the radial direction by the movement of the regulating claw 30. Around it is a small disk 2 that rotates in the same way as the planetary gear 26, which rotates on its own axis.
The eccentric pin 28 of No. 7 moves around the stationary gear 25 in a cycloid curve. This eccentric pin 2
Since the guide pin 32 serves as a slide guide with center point 8, the tip of the regulating claw 38 is radially directed toward the outer circumference of the drum 1 at a position where it starts to come into contact with the overturned capsule. This is very convenient for raising up an overturned capsule, and as the claw progresses, the tip of the claw gets closer and closer to the outer periphery of the drum. When the capsule is thus completely erected in the long hole 5 for transferring the capsule, the body side of the capsule faces the outer periphery of the drum. This means that when the capsules were previously fed to the drum, they fell down with their caps facing downwards, that is, they stood upright in the same direction as the 65% capsules 7b that did not require posture adjustment. After this, the claw 30 approaches the outer periphery of the drum 1, and since the direction of rotation of the eccentric pin 28 of the small disk 27 and the drum 1 coincide, it begins to move forward faster than the rotating speed of the drum, and for this reason, the upright capsule It is moved forward from the position of the posture regulating groove 4 and moves to the capsule entrance/exit hole 2 while remaining upright.

Therefore, at the capsule fall starting point A in FIG. 7, the capsule is completely free in the hole 2, and since there is nothing to hold it, it starts falling to the outside. The capsule that starts falling here will finish falling within a short period of time to the vertical layer of the drum. The fallen capsules are normally supplied by falling to a disc i4 which rotates synchronously with the drum 1 and has a number of holes 5 slightly larger than the capsule diameter perforated on the circumference. The process until the capsule is oriented and ejected out of the drum is as described above, but until the capsule reaches the falling starting point A shown in Figure 7, the rotational speed of the regulating claw 30' is faster than the rotational speed of the drum. Therefore, the capsule is made to stand upright, but after the capsule starts falling, the direction of rotation of the eccentric pin 28 is opposite to the direction of rotation of the drum. Become.

This means that the capsule will never come into contact with the falling capsule, and the capsule will fall and be ejected without any resistance. In this embodiment, adding four more claws 30 on the same plane as shown in FIG. Since they interfere with each other, it is impossible to do so, so the tip of the fixed shaft 20 is extended as shown in FIG. They are arranged symmetrically in the front and back, and the phase of the regulating claws 30 above and below the valley is set to 4.
5. It is set after being displaced. A total of eight regulating claws 30 whose phases are shifted by 450 are arranged in one row 1 of the drum 1.
In order to enter and exit the capsules corresponding to the eight capsule entrance/exit holes 2, the tooth ratio of the cup rotation gear 22 and the internal gear 18 is set to 8/18 = 4/9, and that of the cup rotation gear 22 is 4 female, and the internal gear 18 is 4/9. That of Nargiya is based on the 9-needle model. As shown in FIGS. 5 and 7, the vertical line of the drum 1 and the line connecting the center of the cup 19 for swinging and rotating the regulating claw 30 and the center of the drum 1 have a difference of 50 J and are the same. The reason why the capsule is not on the line is to speed up the starting point A of the capsule's fall, and to give it enough time to fall until it reaches the perpendicular line of the drum 1.

Since the present invention has the above-mentioned configuration, it is possible to easily replace the drum according to the standard number of capsules, and the direction of only the 35% of capsules that statistically require posture adjustment can be adjusted. It is very rational, and its effect in regulating the posture of the capsule is remarkable.
