DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of an apparatus for filling granules according to the present invention will be described below with reference to a case where the apparatus is used in a blister packaging machine for packaging capsule type tablets (hereinafter referred to as capsules). I do. 1 and 2, the filling device of the present embodiment is indicated by 1 as a whole. This filling device 1 is roughly divided into a chute 2 disposed above a transport path of a packaging film f on which a container r is formed.
A transfer mechanism 3 disposed above the conveyance path adjacent to the chute 2, a first pusher 4 for transferring the capsule n in the chute 2 to the transfer mechanism 3, and a capsule m in the transfer mechanism 3 r and a second pusher 6 for extruding into the r, which are arranged in a positional relationship as shown in FIGS. 1 and 2.

In FIGS. 1 to 7, the chute 2
The main body frame 100 of the blister packaging machine is provided with a chute main body 20 fixed and supported in a cantilever manner. In this embodiment, the chute body 20 is composed of a plurality of parts 20a to 20f for convenience in processing, but may be composed of a plurality of parts divided into smaller parts or a single integrated part. Good. The portion 20b of the chute body 20
As shown in FIG. 8, it is formed in a rectangular plate shape as a whole, and its long side is perpendicular to the transport direction of the packaging film f (FIG. 1).
(See FIGS. 2 and 5) and with the short side facing up and down (see FIGS. 2 and 5). As shown in FIG. 5, a plurality of through holes 21 penetrating vertically are formed in the portion 20b. In this embodiment, two through-holes 21 are formed as a set of five through-holes, as shown in FIG.
An interval (inter-center interval) between adjacent through holes in one set of through holes 21 is L. A supply port 22 is formed in the chute body 20 at the lower end of the through hole 21 and penetrates in a direction perpendicular to the through hole. The chute main body 20 is further formed with an elongated slit 23 that communicates with the outside through the through hole 21 on one side (the right side in FIG. 5). The coiled tube 25 is inserted into the through hole 21 to a position where the tip (the lower end in FIG. 5) is adjacent to the supply port. The coiled tube 25 is formed by spirally winding a stainless steel wire into a conduit through which the capsule passes, and provides corrosion resistance to the conduit and prevents static electricity. The minimum width w1 of the supply port 22 is set to be slightly smaller than the outer shape of the capsule m so that the capsule does not fall freely or fall over through the supply port.

In the above-mentioned chute, the capsule m is continuously fed into the through-hole through the coil-type conduit 25 inserted into each through-hole 21 with the longitudinal direction of the capsule up and down. In this case, the capsule falls freely in the conduit, and stops in a state where the leading capsule is in contact with the portion 20e arranged below the portion 20b of the chute body. At this time, the capsule does not fall over due to the size of the supply port 22, and keeps the longitudinal direction up and down.

Referring to FIGS. 1, 2, 9 and 14,
The transfer mechanism 3 includes a drive shaft 31 rotatably supported by a cylindrical support member 30 fixed to the main body frame 100 of the blister packaging machine, and a rotating body 32 fixed to the drive shaft 31. The drive shaft 31 is disposed so as to protrude above the transport path of the packaging film f such that the axis is perpendicular to the longitudinal direction of the packaging film f, that is, the transport direction. The rotating body 32 is circumferentially positioned with respect to the drive shaft via a connecting member 33 and a set screw 34 fixed to an end (lower end in FIG. 10) of the drive shaft 31 so as not to rotate with respect to the drive shaft. It is fixed so as to be adjustable (the rotational body can be adjusted with respect to the connecting member by elongating a hole formed in the connecting member and through which the set screw 34 is passed). The rotating body 32 is integrally formed with an arm 32a that protrudes in a tangential direction and extends in the axial direction of the rotating body. A transfer jig 35 is fixed to the distal end of the arm 32a via a plurality of setscrews 36, and rotates around the axis of the drive shaft together with the rotating body 32 and the drive shaft 31. The drive shaft 31 is reciprocated in the range of the angle θ by a mechanism having a known structure in conjunction with the operation of the entire blister packaging machine. Also,
The transfer jig 35 is radially separated from the rotating body because a pushing member of a second pusher described later is arranged between the transfer jig and the rotating body 32.

As shown in FIG. 11, the transfer jig 35 has an outer surface 35a in the radial direction (lower side in FIG. 11) forming an arc surface with a radius R about the axis of the drive shaft 31. .
In the apparatus of the present embodiment, the transfer jig 35 is formed with two pockets 37 along the rotation direction and ten pockets 37 along the axial direction of the rotating body, for a total of 20 pockets 37. Of the pockets arranged in the rotation direction, the pocket in the front row as viewed in the clockwise direction is 37b, and the rear pocket is 37a.
The pockets arranged in the axial direction form a set of five pockets, and the space between adjacent pockets (space between centers) in the same set is:
It is the same L as the interval between adjacent through holes of the chute. On the other hand, the interval between the two pockets 37 formed in the direction of rotation of the transfer jig is equal to the pitch between adjacent containers formed in the container film f in the longitudinal direction, that is, in the transport direction of the container film. It is the same P. The width w _{2 of the} pocket 37 depends on the granular material to be handled, ie, the capsule m.
Is slightly smaller than the outer shape d of the capsule m so that when the capsule m is inserted into the pocket 37, the capsule is slightly pushed and does not fall freely from the pocket. On the rear side of the pocket 37 (upper side in FIG. 13 opposite to the arcuate surface 35a), a convex portion 38 slightly protruding toward the center of the pocket is formed. This projection prevents the capsule from slipping out of the back of the pocket.

In the transfer mechanism having the above structure, the driving shaft 3
1. The rotating body 32 and the transfer jig 35 are stopped at a position where the pocket 37a is aligned with the supply port 22 of the chute 2.
In this state, the capsule m in the chute 2 is pushed into the pocket 37a through the supply port 22 by the first pusher described later in detail. Next, when the insertion of the capsule into the pocket 37a is completed, the drive shaft 31 slightly rotates counterclockwise, so that the rotating body 32 and the transfer jig 35 also rotate in the same direction, and the pocket 37b shoots. 2 with the supply port 22. Then, the capsule in the chute is pushed into the pocket 37b through the supply port 22 as before. When the insertion of the capsule into the pocket 37b is completed, the drive shaft 31, the rotating body 32, and the transfer jig 35 rotate counterclockwise until the transfer jig 35 faces directly below, and the pockets 37a and 37b are turned. Aligns with two rows of containers (rows of containers arranged in the width direction of the packaging film) formed on the packaging film f transferred under the transfer mechanism. In this position, the capsule is pushed into the container into the pocket by the second pusher described below.

3 to 7, the first pusher 4 is provided on a portion 20d of the chute main body 20 in a direction parallel to the feeding direction of the packaging film f and at right angles to the portion 20d (therefore, the drive shaft 31 of the transfer mechanism 3). A pair of guide rods 41 fixed at a distance (at right angles to the axis OO of
A movable frame 42 is supported by the guide rod 41 so as to be movable along the guide rod. The movable frame 42 is a rectangular body that extends long along the direction in which the plurality of through holes 21 of the chute 2 are arranged, and has a concave portion 42a formed on the upper surface thereof. Recess 4 of movable frame 42
A total of 10 guide rails 4 are provided in a set of 5
3 are arranged in parallel with each other along the direction in which the movable frame 42 extends, and in parallel with the guide rod 41. The adjacent guide rail 4 of the set of guide rails 43
The distance between the three through holes 3 is set to the same L as the distance between adjacent through holes in a pair of through holes 21 of the chute 2. The center of the guide rail 41 is located at the corresponding through hole 21 and the supply port 2.
It is set to be the same as the center of 2.

A slider 44 is movably mounted on each guide rail 43, and an extruding member 45 is mounted on each slider 44. At one end (the right end in FIG. 5) of each of the pushing members 45, there is formed a tip portion 45a whose cross-sectional dimension is large enough to enter the supply port 22 of the chute 2 and extends near the supply port of the chute. .
A hole 45b extending inward is formed at the other end of the pushing member 45, and a spring 46 is inserted into the hole 45b.
The spring 46 is fitted to the outside of a pin 47 fixed to a position on the rear (left side in FIG. 5) wall of the movable frame parallel to the guide rail 43 and at a position aligned with the hole 45b. Accordingly, the spring 46 is prevented from dropping out of the hole, and the pushing member 45 is connected to the movable frame 42 by the shoulder 45c.
Until it comes into contact with the front side (right side in FIG. 5) wall.

The first pusher 4 further includes an operating shaft 51 disposed above the movable frame 42 and extending along the direction in which the movable frame extends. The operating shaft 51 has one side (the right side in FIG. 3) rotatably supported via a bearing on a bearing member 50 fixed to the frame of the blister packaging machine, and the other end (the left end in FIG. 3).
Is rotatably supported on the end wall 20f of the chute main body of the chute 2 via a bearing. Arm members 52 are fixed to the operation shaft 51 at positions adjacent to the ends of the movable frame 45, respectively. A groove 52a is provided at the tip of the arm member.
Are formed, and a roller 53 rotatably attached to an end of the movable frame 45 is received in the groove. The operating shaft 51 is reciprocated within a predetermined range in conjunction with a drive mechanism (not shown) for performing the operation of the entire blister packaging machine.

At the positions at both ends (upper and lower ends in FIG. 7) of the movable frame 42 and at the positions on the trailing edge wall side (left side of the movable frame in FIG. 5), sensors 49a and 49b for detecting malfunction of the pushing member 45 are provided. Is attached. This sensor is a photoelectric sensor, one of which is constituted by a light emitting device and the other is constituted by a light receiving device. These sensors 49a and 49b allow the pushing member 4 to be moved for some reason even when the movable frame moves forward (to the right in FIG. 5).
5 cannot advance and push out the capsule in the through hole 21 of the chute. Therefore, when the pushing member is displaced toward the trailing edge wall of the movable frame against the pressing force of the spring, the pushing member 45 is moved between the two sensors. The rear end 45d enters and the operation failure is detected by blocking the light from the light emitting device to the light receiving device.

In the first pusher 4, the operating shaft 5
Reference numeral 1 denotes a standby state in which the arm member 52 is in a state shown by a solid line in FIG. When the capsule in the through hole 21 of the chute 2 is pushed out of the through hole through the supply port 22, the arm member 52 is rotated by the operating shaft 51 in the counterclockwise direction in FIG. Then, the movable frame 42 is guided by the guide rod and is moved rightward in FIGS. 4 and 5.
Since the slider 44 and the pushing member 45 supported by the guide rail of the movable frame 42 are resiliently pressed toward the portion 20b of the chute body 20 by the spring 46, the distal end portion 45a of the pushing member 45 enters the chute 2 supply port 22. The capsule m at the lower end of the through hole 21 is pushed out of the through hole from the opposite side. When the transfer jig is on standby 35 adjacent to the chute body 20, the capsule is pushed into the pocket 37a or 37b of the transfer jig. When the capsule cannot be pushed out for some reason, the pushing member is pushed to the rear side (the left side in FIG. 5) of the movable frame against the pressing force of the spring 46.

9 to 11, the second pusher 6 is located at a position deviated from the transport path of the packaging film (FIG. 1).
0), the bearing member 6
1 is an operating shaft 62 provided to be movable in the vertical direction.
And a mounting member 63 fixed to the upper end of the operating shaft.
And the pushing member 6 attached to the attaching member
4 is provided. The extruding member 64 is formed of a rectangular member extending parallel to the drive shaft 31 of the transfer mechanism 3 and the packaging film, and has a plurality of extruding convex portions 65 formed on the lower side so as to protrude downward. The extruding protrusions 65 are arranged in pairs in the width direction of the extruding member 64, that is, in the transport direction of the packaging film. Two sets are arranged as one set. The distance between the centers of the pair of extrusion protrusions 65 separated in the width direction of the extrusion member is the same as the distance P between the centers of the pair of pockets formed on the transfer jig. In addition, the distance between adjacent extrusion protrusions of the set of extrusion protrusions is the same as the distance L between adjacent through holes 21 formed in the chute main body. The operating shaft 62 is moved up and down by a drive mechanism (not shown) that operates the entire blister packaging machine.

In the second pusher 6, when the transfer jig 35 in which the capsule m is put in the pocket is moved to a position immediately above the container r formed on the packaging film as shown in FIG. When the operating shaft 62 is lowered, the pushing member 64 is lowered, and the pushing convex portion 65 pushes the capsule contained in the pocket into the container.

As shown in FIG. 5, an ion emitting device 7 is provided adjacent to the chute main body 20 of the chute 2. This ion emitting device 7 is composed of a portion 2 of the chute main body.
A support frame 71 extends along the upper edge of the portion 20b along the direction in which the portion 20b extends, and a discharge nozzle 72 attached to the support frame 71. The number of the discharge nozzles is the same as the number of the through holes 21 formed in the portion 20b, and the discharge nozzles are arranged at the same interval as the interval L between the through holes in the longitudinal direction of the support frame. The discharge nozzle 72 has a tip directed toward the slit 23 as is clear from FIG. 5 so that ions can be emitted to the coiled tube 25 passed through the slit through the slit 23 formed in the portion 20b.

Next, the overall operation of the filling device will be described. Each through hole 2 of the chute 2 through the coiled tube
Inside 1, capsules m to be filled are continuously fed by free fall. And the capsule at the tip is supply port 2
It stops at a position that matches 2. On the other hand, the transfer jig 35 of the transfer mechanism 3 is stopped in a state where it faces the chute 2 and is adjacent to the chute body portion 20 b and one pocket 37 a of the transfer jig is aligned with the supply port 22. . In this state, the operating shaft 51 of the first pusher 4 operates to move the movable frame forward. For this reason, the pushing member 4
5 is also pushed by the spring and moves with the movable frame, and pushes the capsule m in the through hole 21 into the pocket 37a of the transfer jig via the supply port 22 at the tip. When the pushing of the capsule into the pocket 37a is completed, the movable frame 42
Is retracted, and the drive shaft 31 of the transfer mechanism slightly rotates counterclockwise, so that the pocket 37 b of the transfer jig is aligned with the supply port 22. The capsule moves by one in the chute through hole 21 and stops at a position where the next capsule is aligned with the supply port. Then, the operating shaft 51 of the first pusher operates again to move the movable frame 42 forward, and the pushing member pushes the capsule in the through-hole through the supply port to the transfer jig 35.
7b.

Next, the drive shaft 31 of the transfer mechanism is further rotated counterclockwise to move the transfer jig 35 directly above the container formed on the packaging film, and the pockets 37a and 37b are moved to the corresponding containers. matches r. When the transfer jig moves right above the container, the operating shaft 62 of the second pusher 6 is at the raised position, and the pushing member 64 is at the upper position as shown in FIG. When the transfer jig stops, the operating shaft 62 descends and simultaneously pushes the capsules contained in the pockets 37a, 37b of the transfer jig 35 downwardly toward the corresponding container r by the push-out protrusion 65, and the container is pushed out. Put in r. When the insertion of the capsule into the container is completed, the operating shaft 62 rises, and the pushing member also rises to the upper position.
When the drive shaft 31 of the transfer mechanism rotates clockwise, the transfer jig moves to a position where the pocket 37a is aligned with the supply port and prepares for the next operation. As is apparent from the above description, in this embodiment, the operation of inserting the capsule in the pocket into the container is performed once in units of two rows of pockets. Hereinafter, the capsule is filled in the container by repeating the same operation as described above.

FIGS. 15 and 16 show a modification of the transfer mechanism. In the transfer mechanism of this modification,
The transfer jig 35 'is formed in a hollow cylindrical shape, and a plurality of pockets 37' are formed at equal intervals in the circumferential direction, and two sets of five in the axial direction are arranged in a straight line. ing. Further, the pushing member 6 of the second pusher 6 ′
There are only ten 4 'extrusion protrusions 65' in a row along the rotation axis of the transfer jig. In this modified example, the transfer jig 35 ′ is intermittently rotated with the distance between adjacent pockets circumferentially spaced in a certain direction as one pitch, and the capsule is placed in the pocket at a position aligned with the supply port 22 of the chute 2. When the one row of pockets containing the capsules is moved right above the container r, the pushing member descends and pushes the capsule into the container by the pushing protrusion. In this modification, the operation of filling the capsule into the container is performed in units of one row of pockets.

In the above-mentioned embodiment, since the capsule to be handled is an example of a capsule tablet having elasticity in the radial direction, the inner wall of the pocket of the transfer jig does not have elasticity. For example, in the case of an inelastic material such as a sugar-coated tablet, the inner wall of the pocket may be formed of an elastic member, and the granular material may be held by elastic deformation of the inner wall.

[0026]

According to the present invention, the following effects can be obtained. (1) Since the insertion of the granular material from the chute into the pocket of the transfer jig and the insertion of the granular material from the pocket into the container are performed by the pusher, a stable filling operation can be performed. (2) If a problem occurs in the operation of inserting the granular material from the chute into the transfer filling pocket due to the adhesion of the granular material or the like, this fact can be detected, and the problem of filling the damaged granular material can be prevented. (3) Even a capsule tablet with a light content can be filled reliably. (4) Since the movement of the granular material in the chute is not hindered by the static electricity, the filling operation can be stably performed even with the granular material made of an easily charged material such as a capsule.
