Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a device for correcting the posture of tablets. Concerning a correction device that can be placed correctly in a pocket.

(@ Conventional equipment When filling tablets into the pockets formed in the packaging film, it is difficult to fill the tablets 100% depending on the shape of the tablets, and even if there are missing tablets, the tablets may become erect in the pocket or half-filled. It may not stick out.

In order to solve such problems, the applicant filed a practical application in 1973.
No. 4'-23795, ``Tablets, etc. Filling'') 1 Apparatus'' was provided. This device is designed to knock down a tablet stored in an upright position in a pocket.It operates in a direction perpendicular to the direction of film flow, and the correction light J of the tablet stored in an upright position in the pocket is used to Although this technique is very effective, it is not possible to sufficiently correct tablets that are filled in such a way that they partially protrude from the pockets in the direction of film flow, resulting in correction errors in some cases.

(c) Purpose of the Invention The present invention has been made in view of the above four points of the conventional tablet filling device, and its purpose is to correctly insert a tablet into the pocket even if the tablet is protruding from the pocket. The purpose of the present invention is to provide a posture correcting device that can perform the following tasks.

B) Structure of the Invention The present invention provides an apparatus for correcting the posture of a tablet filled in a pocket formed in a packaging film while transporting the packaging film, in which the tablet is placed downstream from the position at which the tablet is filled into the core pocket. a first correction roller that is rotatable about an axis substantially perpendicular to the direction of travel of the film and that protrudes upwardly from the packaging film and that corrects the posture of the tablet by contacting the tablet; and a second correction roller that is rotated about an axis forming a predetermined angle in the direction of travel of the tablet and that protrudes upward from the packaging film and contacts the tablet to correct the posture of the tablet. .

←l→ Embodiment In FIGS. 1 to 6, the tablet posture correcting device 1 of this embodiment transports the tablet m in the 3 in the packaging film f on the downstream side from the supply position A. The first one is arranged on the upper part of the packaging film to be separated in the machine direction.
The posture correction mechanism 2 and the second posture correction mechanism 4 are provided.

The first posture correction mechanism 2 includes a support shaft 21 which extends above the packaging film and is fixed by a known method with its axis substantially perpendicular to the traveling direction of the packaging film r;
A lever 22 rotatably attached to the support shaft 21 for each packet formed on the packaging film f (each pocket formed side by side in the horizontal direction of the packaging film f);
It has a first correction roller 26 rotatably attached to the lever 22 by a shaft 26, and a spring-up prevention plate 24 formed integrally with the lever adjacent to the correction roller at the tip of the lever. . The lever 22 is moved so that the correction roller 2 is in contact with the upper surface of the packaging film f.
5.

Therefore, the correction roller 26 rotates in the same direction as the packaging film f moves.

The second posture correction mechanism 4 includes a long frame 41 which is arranged and fixed by a known method across the upper part of the packaging film f.
and a shaft 4 rotatably attached to the frame 41 by a bearing 42 so as to make a predetermined angle θ with the direction of travel of the packaging film for each pocket p, and a cylindrical shaft 43 fixed to each shaft 43. It has two correction rollers 44. A bevel gear 45 is fixed to the end of the shaft 46. The frame 41 is further provided with an upright shaft 46 for each shaft adjacent to the end of the shaft 46 so as to be freely rotatable via a bearing 47.

A bevel gear 4 meshing with a bevel gear 45 at the lower end of each shaft 46
8 is fixed, and a belt pulley or pulley 49 is attached to the upper end.
is fixed.

A driving pulley 50 driven by a motor 51 is disposed at the upper part of the frame 41 at approximately the center thereof. A belt 52 is passed between the drive pulley 50 and the plurality of pulleys 49, and the belt is pushed against the pulleys 49 by a tension roller 54 rotatably provided on the frame 41.

Next, the operation of the posture correction device will be explained with reference to FIGS. 4 to 6.

The packaging film f is continuously transported in the direction of arrow X, and at position A, tablets m are filled into pockets l-p using a known filling device. The first correction roller 26, which is in contact with the packaging film due to its transport, moves in the counterclockwise direction (
(in Fig. 2). The bell) 524 of the second attitude correction mechanism 4 is continuously moved by the main motor 50 in the direction of arrow Y (in Figure 1 to g), continuously rotates the pulley 49, The correction roller 44 of No. 2 is continuously rotated in a fixed direction.
There are also those shown in El. And Figure 4 (A
When the filled lock ^11m comes under the first correction roller 223 in the posture shown in 51a (Al), it contacts the correction roller 2 roller '1'' as shown in 51a (Al). It is not possible to correct the posture of the tablet. Therefore, it remains in this posture; it moves to the position of the correction roller 44 of 2. At the entrance side of the correction roller 44 (on the left side in FIG. 1), as shown in FIG. (A
l vc As shown, it is on the left side of Bokent p, and on the exit side it is on the right side of Kerat at H as shown in Figure 6 ((T)), and the correction roller 4A is rotated counterclockwise As the pocket and therefore the tablet m move, the tablet comes into contact with the correcting roller 44 and is brought down into the pocket p in the correct posture as shown in FIG. 6 FB).

On the other hand, if the tablet is filled in the position shown in FIG. ) or [C]
As shown in FIG. 2, the posture is corrected by engaging with the correction roller 26. Therefore, in this case, no correction by the correction roller 44 is necessary.

Next, when the packaging film f is filled in the state shown in FIG. 4(D), since the packaging film f moves in the direction of the arrow X, the correction roller 26 pressed against the packaging film as shown in FIG. 5(Dl) Rotate counterclockwise to push tablet m into pocket p.

In addition, when the tablet is filled as shown in Fig. 4 (E), the correction roller 2 is placed on the tablet as shown in Fig. 5 (E), and the tablet is filled as shown by the imaginary line. When the correction roller 26 climbs over the tablet, the tablet is pushed into the pocket and placed. When the tablet springs up, it is prevented from flying out from the pocket l- by the anti-slip plate 24 shown in FIGS. 2 and 6. Therefore, the tablet in the state shown in FIG. 4(D) (El) also hardly needs correction by the correction roller 44.

As described above, in the posture correction device of the present invention, since the correction is performed using the first and second correction rollers, it is possible to fill the tablet in the pocket in the correct posture.
