Description

[Detailed Description of the Invention] The present invention relates to a tablet chute in a tablet feeding device of a forming and filling machine.

Generally, preparation of the forming film is not completed when the forming/filling machine is started, so it is desirable to temporarily stop the tablet filling operation so that filling can be performed immediately after the preparation is completed.

Therefore, it is necessary to provide an openable and closable shank near the lower end of the tablet chute for aligning and feeding tablets.

However, once the tablets are stopped from falling in the chute by the shank, due to the shape of the tablets, the tablets intersect with each other in the chute, creating lateral pressure on the side surface of the chute, causing clogging.

This clogging phenomenon appears more prominently in lens-shaped tablets where the periphery is thinner than the center.

If such a clogging phenomenon occurs, the tablets will not come out from the outlet of the chute even if the shutter is opened, resulting in a problem that restarting tablet filling becomes uncertain.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a tablet chute that corrects the posture of a tablet that has become jammed to release the jam.

The present invention provides a tablet shoe (with a shank at the bottom of the chute that selectively closes a chute passage), a slit extending along the chute passage in the side wall of the chute, and a slider adjacent to the chute. The slider is provided so as to be reciprocally movable along the extension direction, and a straightening pin that protrudes into the chute passage through the slit is attached to the slider so as to be flexible via a spring, and the straightening pin is moved by the slider to the lower side of the chute. It is configured to reciprocate between the lowest position and the highest position above the shank.

An embodiment of the tablet chute according to the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, 1 is a tablet chute according to the present invention, 2 is a chute body, and 3 is a vertical groove formed in the chute body to define a passage for tablets to fall.

The opening of the groove 3 is formed by a cover 5 fixed to the main body 2 so as to form a slit 4 extending along the direction of extension of the passage.
covered by.

A slider I is attached to a guide rod provided near the main body 2 along the direction of extension of the passage, and is moved along the guide rod by, for example, a fluid pressure cylinder.

A correction pin 8 whose tip passes through the slit 4 and projects into the chute, that is, into the passage, is attached to the slider 7 via a coil spring 9.

A shaft 10 is provided at the bottom of the chute body 2 and can be selectively protruded into the groove 3, i.e., the passage.
It is designed to stop the tablet T from falling.

The groove 3 of the chute is connected to a known tablet feeder via a coil spring chute 11, and tablets T are fed from the tablet feeder.

In the tablet chute having the above structure, while tablets are being fed from the chute 1 into the pocket P formed in the packaging film, the shaft 10 is retracted from the passage as shown in FIG. 1, and the straightening pin 8 As shown by the broken line in FIG. 1, the tablets are constantly operated from the lowest position to the highest position to prevent tablets from becoming jammed.

Further, even if the tablet T becomes clogged due to the closure of the shell 10, the correction pin 8 is reciprocated above the slit 4 as shown by the solid line in FIG.

Therefore, the posture of the tablet T stuck in the passage of the chute is corrected by the correcting pin, and the tablet T can fall smoothly in the chute.

As described above, in the tablet chute 1 according to the present invention, it is possible to easily release tablets from clogging in the chute, so that tablets and the like can be stably supplied.

Moreover, since the correction pin is connected to the slider by a spring, there is no possibility that the pin will damage the tablet.
