In order to solve the above-mentioned problems, according to the present invention, tablets are supplied from a hopper of a tablet storage and unloading device to a chute of a packaging device, and tablets discharged from the chute are laminated. In the tablet packaging device for packaging tablets, the packaging device is provided on one side of the lower portion of the tablet storage and unloading device , and the chute is disposed above the lower end outlet of the hopper, and between the chute and the lower end outlet of the hopper.
Conveys tablets discharged from the hopper exit to the chute
Bucket conveyors are installed in double rows, and the hopper and bucket conveyor
Discharged from hopper between pill receiving end of the carrier
Tablets are distributed to buckets on a double row
A configuration in which a sorting device for feeding is provided is adopted.

[0006]

[0007]

As described above, by disposing the packaging device on one side of the lower portion of the tablet storage and unloading device and removing the packaging device from below the hopper, only the space corresponding to the excluded space is obtained. An extra tablet feeder can be provided.

[0008]

A plurality of tablet supply units U having a plurality of the above-mentioned tablet feeders 2 may be arranged in front and rear, right and left,
Alternatively, they may be arranged in a cylindrical shape.

As shown in FIG. 2, the packaging device 20 is provided with a triangular plate 21 for folding the laminated paper S in the width direction into a pair with a pair of triangular plates 21 in a transfer path of the thermally fusible laminated paper S transported in one direction. Seal rollers 22a and 22b are provided, a chute 23 is provided between the seal rollers 22a and 22b and the triangular plate 21, and tablets are supplied from the chute 23 between two folds of the laminated paper S, and the seal rollers 22a and 22b
The tablet is packaged by the action of heat-sealing both side edges of the laminated paper S and the width direction in a band shape.

The packaging device 20 is a tablet storage and retrieval device 1
The chute 23 is disposed above the lower end outlet of the hopper 4.

A hopper 4 is provided between the hopper 4 and the chute 23.
A transport device 30 is provided for transporting the tablets discharged from the lower end outlet to the chute 23.

[0017] The transport device 30 consists of a bucket conveyor
You . As shown in FIGS. 3 and 4, the bucket conveyor 30 is provided with a guide rod 33 parallel to a screw shaft 32 rotated by a motor 31, and linearly reciprocates along the guide rod 33 by the rotation of the screw shaft 32. An arm support piece 35 is provided on the front side of the bucket support 34 to be moved, and one end of the bucket arm 37 is fixed to a pin 36 rotatably supported by the arm support piece 35.
7, a bucket 38 is fixed to the other end.
Is moved from a position below the hopper 4 toward the chute 23.

An L-shaped roller arm 39 is fixed at one end to the end of the pin 36, and a first roller 40 and a second roller 41 are rotatably mounted on both ends of the roller arm 39. The bucket arm 37 is deflected in one direction by a spring 42 provided on the outer side of the bucket, and the lower surface of the bucket 38 is brought into contact with the receiving piece 43 provided on the upper surface of the bucket support 34. The attitude of the roller arm 39 is kept constant so as to be located above.

Further, a cam member 44 is provided at the front of the transfer path of the roller arm 39 that moves together with the bucket support 34, and the cam member 44 guides the movement of the second roller 41 to move the bucket 38 around the pin 36. An inclined surface 45 having an upward slope for turning upward, and a stopper surface 46 with which the first roller 40 abuts when the second roller 41 moves to the upper end of the inclined surface 45 are provided. The bucket 38 is further rotated upward by an operation in which the bucket support 34 moves further forward from a state in which the bucket 38 contacts the stopper surface 46.

In the drawing, LS ₁ denotes a limit switch for stopping the forward movement of the bucket support 34, and LS ₂ denotes a limit switch for stopping the backward movement.

The bucket conveyor 30 having the above configuration
Are provided in double rows between the hopper 4 and the chute 23 .
And the end of the bucket conveyor 30 on the tablet receiving side.
Between the lower end of the hopper 4 and the tablets falling from the hopper 4.
In the bucket 38 of the bucket conveyor 30 in a row.
A sorting device 50 for feeding is provided.

Here, the sorting device 50 is configured to rotate the tablet tray 51 provided below the hopper 4 right and left by the operation of the motor 52.

The tablet packaging apparatus shown in the embodiment has the above-mentioned structure, and the tablets discharged from the tablet feeder 2 are supplied into the hopper 4 from the drop guide path 3, and discharged from the lower end outlet of the hopper 4. Tablets are received in a saucer 51.

Each time a tablet is supplied, the tray 51 is
Due to the drive of No. 2, it is rotated alternately in the left-right direction. For this reason, the tablets supplied into the tray 51 are alternately supplied to the buckets 38 of the double row bucket conveyor 30.

The motor 31 of the bucket conveyor 30 operates when the tablets are supplied into the bucket 38, rotates the screw shaft 32, and moves the bucket 38 toward the chute 23.

When the bucket 38 is moved to a position close to the chute 23, the second roller 41 moves along the inclined surface 45 of the cam member 44, and the movement causes the roller arm 39 to swing, thereby causing the pin 36 to move. Rotation of bucket 3
8 is swung upward.

When the second roller 41 moves to the upper end of the inclined surface 45, the first roller 40 comes into contact with the stopper surface 46. The bucket support 34 is further moved forward from a state in which the first roller 40 abuts against the stopper surface 46, and the bucket 38 swings further upward around the pin 36 by the movement, and the tablets supplied therein are separated. It is supplied to the chute 23 of the packaging device 20 and is packaged by the operation of the packaging device 20.

[0028]

As described above, in the tablet packaging apparatus according to the present invention, the tablets discharged from the hopper of the tablet storage and unloading apparatus are transported upward by the bucket conveyor and supplied to the chute of the packaging apparatus. Since the height of the packaging processing apparatus can be reduced, and the height of the packaging processing apparatus is the same as that of the conventional packaging processing apparatus,
At the height of the space where the packaging device has been removed from below the hopper
An extra tablet feeder can be provided correspondingly, so that a packaging processing apparatus with a large number of stored tablet feeders can be obtained.

Also, the bucket conveyor for supplying the tablets discharged from the lower end of the hopper to the chute of the packaging device is formed in a double row, and the tablets discharged from the hopper are distributed to each of the bucket conveyors by the distribution device and supplied. In addition, the packaging process can be performed efficiently.
