DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on the embodiments shown in the drawings.

FIG. 1 is a perspective view showing the internal construction of a tablet packaging machine showing an embodiment of the present invention. FIG. 2 is a front view showing the internal structure of the carrier of the tablet packing machine of the present invention. FIG. 3 is a side view showing the internal structure of the carrier of the tablet packing machine of the present invention.

Reference numeral 1 denotes a tablet packing machine, which comprises a casing main body 2, a tablet supply mechanism section 3 arranged at an upper part of the main body, and an automatic packaging mechanism section arranged at a lower part of the supply mechanism section. 4 and a transport device 5 that transports tablets from the tablet supply mechanism section 3 to the automatic packaging mechanism section 4.

The tablet supply mechanism section 3 includes a partition plate 6 having a large number of storage sections partitioned in a plane lattice, and a tablet storage section which is inserted into each of the storage sections in the partition plate and arranged in a horizontal plane. It is formed with the supply body 7.

The automatic packaging mechanism section 4 includes a medicine package sheet roll 8
A heat-sealing mechanism 11 for putting tablets into a medicine-packet sheet 10 continuously fed from a medicine-packet sheet feeding section 9 loaded with and heat-sealing, and a medicine heat-sealed as a package by the heat-sealing mechanism. It is composed of a cutting mechanism 12 for cutting the packaging sheet 10 and a package transfer mechanism 14 for transferring the package cut by this cutting mechanism to a discharge port 13 opened on the upper side wall of the tablet packing machine 1.

The transport device 5 includes a hopper 15 for receiving tablets which are selectively dropped and supplied from the tablet storage supply body 7 of the tablet supply mechanism 3, and a pair of left and right first hoppers which receive tablets falling from the hopper. The belt conveyors 16 and 16 function as tablet transportation means, and the shutter conveyor 17 functioning as a second tablet transportation means disposed in the lower center of these belt conveyors. The hopper 15 is provided with a wire net 18 for receiving the tablets falling from the tablet supply mechanism 3.
And a collecting plate 19 arranged under the wire mesh.

A vacuum suction device 20 includes a vacuum suction main body 21 and a duct 22 connected to the main body.
It is formed by. This duct has multiple suction ports 23
Is provided. The respective suction ports are opened upward on the lower side of the pair of left and right belt conveyors 16 as the first tablet conveying means, downward on the upper side of the shutter conveyor 17 as the second tablet conveying means, and the conveyors. The belt is opened on the upstream side in the direction of rotation. Also,
A suction port 23 of a duct 22 is provided below the collecting plate 19 of the hopper 15.

Reference numeral 24 denotes a control device which controls the wrapping of tablets in the tablet packing machine 1 and, at the same time, the vacuum of the vacuum suction device 18 when the belt conveyors 16 and 16 and the shutter conveyor 17 of the carrying device 5 rotate. The suction main body 19 is controlled to operate.

In the tablet packing apparatus constructed as described above, when the tablet packing machine 1 is driven by the controller 24, the tablets dropped from the tablet storage supply body 7 of the tablet supply mechanism section 3 are moved by the wire netting 18 of the hopper 15. The belt is received, collected at the center by the belt conveyors 16 and 16 of the conveying device 5, placed on the shutter conveyor 17 and conveyed to the automatic packaging mechanism unit 4 and loaded into the medicine package sheet 10, and then heat-treated as a package by the heat seal mechanism 11. The cutting mechanism 12 for the sealed medicine package sheet 10
The package is transferred to the discharge port 13 provided on the upper side wall of the casing body 2 by the package transfer device 14 and discharged.

When the tablets are filled in the tablet storage / supply body 7 of the tablet supply mechanism 3, or from the tablet storage / supply body, the hopper 1
When it dropped to 5 and collided with the wire net 18, it was crushed to generate chemical powder and fragments. Then, the powdered medicines and fragments of the medicines in the tablet storage supply body 7 are dropped together with the tablets into the hopper 15, and the belt conveyors 16 and 16 are fed from the hoppers.
Also, while being transported to the shutter conveyer 17 and packaged with another tablet, the powdered medicine or a fragment of the drug dropped on the transport device 5 is sucked by the vacuum suction device 20 and attached to another tablet, or another tablet is packaged. The medicine package sheet 10 is prevented from being mixed.

That is, the carrier device 5 that carries tablets from the tablet supply mechanism part 3 to the automatic packaging mechanism part 4 and is liable to be adhered with drug powder or drug fragments is vacuum sucked when the belt conveyors 16 and 16 or the shutter conveyor 17 rotate. The device 20 is operated to suck the chemical powder and fragments adhering to the belt container and the belt of the shutter conveyor from the suction port 23 through the duct 22.

The suction port 23 for sucking the powdered medicines and the fragments of the medicines attached to the belt conveyors 16 and 16 is opened upward on the lower side of the belt conveyors so that they are attached to the belts and the belts rotate. It is designed to be able to suck in powders and fragments that have become easier to fall on the side. In addition, since the powdered medicines and chips are sucked downward, they are not scattered and are not scattered.

Further, the suction port 23 for sucking the drug powder and the drug fragments adhering to the shutter conveyer 17 is provided on the upstream side in the rotation direction opposite to the direction in which the drug falling from the belt conveyers 16 and 16 is moved by the belt. This prevents the tablets falling from the belt conveyors 16 and 16 from being sucked during the suction.

Since the belt conveyors 16 and 16 and the shutter conveyor 17 clean the tablets each time they are conveyed, the previous medicine powder or fragments may adhere to another tablet, or may be contaminated with the medicine powder or medicine fragments. It is designed to prevent you from doing so.

Further, the chemical powder or the fragments of the drug collected in the collecting plate 19 of the hopper 15 are sucked into the vacuum suction main body 21 from the suction port 23 of the duct 22 provided in the lower part of the collecting plate. Therefore, the carrier device 5 does not require maintenance for regularly removing chemical powder or the like.
