Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a tablet feeding device for appropriately picking out stored tablets and introducing them into a packaging mechanism in a tablet packaging machine.

(b) Conventional tablet feeding devices are thick (separated by temperature).There are two methods, respectively.
Disclosed in the issue. In the former case, a tablet alignment tube is pushed up into the tablet storage section by a solenoid drive, and the tablets are taken into the tube and extracted. In this method, the stored tablets are stirred by thrusting, so that a stable tablet extraction operation is achieved, but the disadvantage is that the operation noise becomes louder. In the latter case, several grooves are formed on the alignment wheel, and the tablets are taken into the grooves while rotating the alignment wheel and allowed to fall naturally from the groove.
This is to extract the tablet. In this method, the tablets are extracted by the rotation of the alignment wheel, so there is little operating noise, but the tablets are extracted by falling naturally, so the extraction speed is slow. In addition, all of the above-mentioned conventional techniques have the disadvantage that the tablets are continuously guided to the ejection port because the tablets are ejected by gravity (the tablets are ejected in a connected manner).

Therefore, it is desirable to have a device that extracts and discharges tablets one by one without depending on the natural falling pressure, but this has the disadvantage that it takes a long time to feed the tablets.

(C) Purpose of the Invention The present invention relates to a rotary tablet feeding device, and aims to reliably feed tablets and speed up the tablet feeding time by taking out tablets in conjunction with rotational operation. .

B) Structure of the Invention The present invention provides a rotating plate, a guide wall formed around one side of the rotating plate, and notches formed at equal intervals in the guide wall,
a claw piece provided corresponding to the notch and attached to the rotary plate so as to be able to reciprocate in a radial direction from the central axis of the rotary plate;
A plurality of ribs are provided around the other side of the rotary plate with gaps corresponding to the notches formed in the kite wall, and an opening having a smaller diameter than the rotary plate is disposed between the rotary plate and the tablet accommodating portion. and a partition plate having a fixed wall that substantially fits on the surface facing the rib provided on the rotary plate so that the rib is on the inside, and a partition plate having a fixed wall formed at a predetermined tablet extraction position 1i [facing the fixed wall]. a tablet ejection opening, a locking member having a hook at one end and supported by the claw so that the claw moves in the same direction on the other side of the rotary plate as the claw moves back and forth; In order to hold the C tablet, a push plate and a claw piece provided corresponding to the movement range of the hook due to the reciprocating movement of the locking member and the claw piece are biased in the axial direction. A control member is provided for controlling the claw piece in conjunction with the rotation of the rotary plate so that the claw piece that reaches the tablet extraction position through the rotation of the rotary plate projects toward the tablet extraction port through the gap between the ribs 5. It is.

In this way, the present invention discharges tablets by the action of the control unit that is linked to the rotation of the rotary plate filO, and in this example, a spring (3:'+ ), a roller 06) attached to the claw piece (5), and an inner cam 1) on which the roller (26) slides in contact with each other constitute a control member. Also, as shown in Fig. 4, the rotation plate (1) has a lip (7).
A push plate (13) is provided on the surface thereof along the reciprocating distance of the hook (of different types) that accompanies the reciprocating movement of the claw piece (5). The partition plate (II+) has a circular opening (8) whose radius is approximately the distance to the shaft (4) when the hook 01 is closest to the shaft (4). & (1), which is equipped with a hook 01), communicates with the tablet storage part (161).The radius of the opening (8) is from the lip (7) to the part (4).
), an annular groove C3 is formed between the opening periphery 02 of the opening (8) and the lip (7). The bottom of the tablet storage section 061 has an opening (8).
The tablet is slanted towards the opening (

Introduce 1 and get it lined up.

Explaining the operation of the above structure, the tablets loaded from the upper part of the base (15) are deposited in the tablet accommodating part (16) and are also introduced into the rotary plate (11) through the opening (8). The lip (7) positioned downward and the opening periphery (321
The rotating plate (11 rotates in the direction of arrow A in FIG. ) is in contact with the second recess (30) of the cam (3), so it is biased by the spring G!51, and the rotating plate (1
), and the other claw piece (5) is attached to the roller (2).

The direction of rotation in 1) is indicated by arrow B. In Figure 4,
Among the tablets arranged on the lower lip (7), the tablet located at the rearmost position in the rotational direction is pressed against the hook 1 which is retracted in the direction of the axis (4) due to the rotation of the rotating plate (1). Board Q3
It is held at 1. The tablet (3fiJ) held by the pusher &Q31 is guided by the fixed wall (9)K and transferred towards the tablet extraction position ftPK.By the rotation of the rotary plate (1), the 26) is the cam (31)
When the roller (26) comes into contact with the first recess (2), it moves slightly in the direction of the claw piece (51 is the notch 13) on which the roller (26) is attached, and then gets caught in this and moves in the direction of the fixed wall (9). In order to do so, the tablet held by the hook (111) should be pushed towards the IM fixed wall (9).Therefore, the tablet will be caught and the tablet will be of a different type.
When held in an imperfect position, this fixed wall (9)
Corrected by biasing in the direction. However, Laura (26
) comes into contact with the second recess GOI of the cam (31), the claw piece (5) fitted with the roller 06) projects outward from the rotating plate (1) through the notch (3) by 1°. Therefore, the nail piece (5
), the hook 01) also protrudes in the radial direction and becomes the lip (7) and the road surface. The tablet is guided outward and extracted from the tablet outlet (3'6).Then, the roller (2fil) that was in contact with the second recess clIll of the rotary plate (11 rotates and cam C31) is removed from the tablet outlet (3'6). When it comes into contact with the circumferential tightening, the claw piece (5) is regulated by the cam 01) and moves in the direction of the axis (4) against the spring 051, and the hook (111) also moves in the direction of the axis (4). Reply (
7) It is possible to hold tablets that are aligned.

In this example, four claw pieces (5) are provided to rotate & (1) once.
The tablets are taken out one by one by V-Wing /4 rotations.

At this time, the tablet held in the groove G formed by the lip (7) and the opening periphery (32) is taken out and held by the hook 011, so that stable tablet extraction is achieved. Drive motor Q8 in response to the tablet ejection signal
1 is operated, and then, when a predetermined detector detects a tablet taken out from the rotary plate fi+, the drive motor 081 is stopped, and one tablet is taken out. Further, when taking out a plurality of tablets, the detection signal of the detector is counted, and when a predetermined number of tablets have been taken out, the drive mode is stopped.

(f) Effects of the Invention According to the present invention, since the tablets are held and extracted in conjunction with the rotation of the rotary plate, it is possible to unify the supply time of nine tablets. Since the tablets in the tablet accommodating section are aligned between the opening periphery of the partition plate and the lip, the tablets are securely held by the hook and the pusher plate, and a stable tablet feeding operation can be performed.
