Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a feeder accommodating portion in which a plurality of passages for guiding tablets discharged from a large number of tablet feeders arranged in the depth direction are provided at right and left intervals. The present invention relates to a tablet packaging machine in which a packaging device is arranged below.

[Prior Art] This type of packaging machine is widely used as an automatic packaging machine for automatically packaging various drugs according to a prescription, but in the conventional device, the lower end of the funnel-shaped chute is The chute was placed along the same axis as the input port of the packaging device, and the lower end of the chute was narrowed to a width smaller than the width of the input port in order to ensure the injection of the medicine (actual exploitation 57
-105201 gazette).

However, in the conventional medicine packing machine, as described above, since the lower end of the funnel-shaped chute is narrowed down to a width smaller than the input port of the packaging device, it is discharged from the tablet feeder arranged at the end of the funnel-shaped chute. The drug repeatedly bounces until it reaches the lower end of the chute, and it took a long time for all of the drugs for one package selected according to the prescription to gather at the lower end of the chute.

Further, there is a restriction on processing of the chute and a demand not to increase the number of rebounds. Therefore, a predetermined height is required to narrow the lower end of the funnel-shaped chute to a width smaller than the inlet of the packaging device. However, in the conventional medicine packaging machine, there has been a large constraint factor for increasing the volume of the tablet feeder accommodating portion.

In order to solve such a problem, it is proposed that the funnel-shaped chute be a small one that corresponds only to the dimension in the depth direction, and that a belt conveyor is arranged between the tablet feeder and the funnel-shaped chute as a horizontal transfer device. (See Japanese Utility Model Laid-Open No. 57-11701).

[Problems to be Solved by the Invention] However, when a belt conveyor device is used,
During the transfer operation, the tablet may change its position without resting on the belt conveyor due to its shape, so the transfer amount of the belt conveyor does not directly change to the tablet transfer amount, and a stable gathering operation for a short time is secured. It was difficult to do.

Further, in the apparatus described in Japanese Utility Model Publication No. 57-11701,
Since the tablets are still assembled in the depth direction using the funnel-shaped chute, in other words, the funnel-shaped chute cannot be completely abolished, and there is a limit to the increase in the volume of the tablet feeder accommodating portion. .

The present invention solves the above-mentioned problems of the prior art, allows tablets discharged from each tablet feeder to be stably collected in a short time and introduced into a packaging device, and further increases the volume of the tablet feeder storage portion. It is an object of the present invention to provide a tablet packaging machine capable of processing the same.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a feeder housing in which a plurality of passages for guiding tablets discharged from a large number of tablet feeders arranged in the depth direction are provided at right and left intervals. In a tablet packaging machine in which a packaging device is arranged below the section, a trough-shaped first bottom plate that extends in the depth direction and receives a dropped tablet and reciprocates on the bottom plate below each of the passages. A first collecting means for dropping the tablets on the bottom plate from the drop holes at the forward position is provided, and a gutter for receiving the tablets dropped from the drop holes extends in the direction connecting the drop holes below the drop holes. A second bottom plate having a shape of a circle, and second collecting means for reciprocating on the bottom plate and introducing the tablets on the bottom plate into the packaging device at the forward position thereof.

[Operation] By adopting the above means, the present invention can completely eliminate the funnel-shaped chute, and can increase the volume of the tablet feeder accommodating portion without increasing the height of the entire apparatus. Further, by using the reciprocating collecting means as the transfer device, the collecting operation of the tablets can be stably performed in a short time.
