Description

TECHNICAL FIELD The present invention relates to an article transfer device for accurately transferring articles such as tablets while aligning articles in different directions at high speed.

[Conventional technology and its problems]

As a method for moving an article such as a tablet from a horizontal direction to a vertical direction, a method of utilizing a dropping force due to the weight of the article and a method of mechanically pressing the article to give a dropping force have been proposed.

However, in the former self-weight drop method, if the horizontal moving force of the article is large, that is, if the horizontal moving speed is higher than the falling speed, the article may be gripped at the conversion position where it moves from horizontal to vertical and may not fall. On the contrary, if the horizontal moving force is small, the frictional resistance at the horizontal moving portion is large, and it becomes difficult to move in the vertical direction only by the horizontal moving force, or the article rotates to maintain the regular shape. It becomes difficult. Further, there is a limit to the speedup, and it is not suitable for the speedup.

On the other hand, in the latter mechanical drop method, there is a risk that the article will be scratched by a pusher or the like, and when the timing is adjusted to the next step, the mechanism becomes complicated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an article transfer device which has a simple structure and can transfer an article from a horizontal direction to a vertical direction at a high speed without damaging the article.

[Means for solving problems]

In order to achieve the above object, the present invention relates to an article transfer device for vertically transferring horizontally aligned articles, and a substantially horizontally extending cylindrical guide for receiving the articles aligned in the horizontal direction, and the introduction guide. A vertical pipe connected to the opening on the other end side of the guide and having a plurality of exhaust ports formed at substantially equal intervals in the circumferential direction of the peripheral wall, and a pressure fluid blow-out pipe opened near the upper portion of the connecting portion between the introduction guide and the vertical pipe. The gist of the present invention is that the downward pressure fluid ejected from the pressure fluid ejection pipe sucks the article in the introduction guide and transfers the article downward.

[Action]

The pressure fluid vertically imparts an accelerating force equal to or higher than the dropping force due to its own weight to the article in the vertical pipe, and at the same time, imparts a suction force by the ejector effect to the article located in the introduction guide. As a result, the article is transferred from the rotating disk through the introduction guide to the vertical tube at high speed and smoothly.

Further, the pressure fluid is uniformly discharged from the exhaust port provided on the peripheral wall of the vertical pipe while flowing down the vertical pipe.
The articles are transferred downward without deviating from the center position of the vertical tube, that is, without contacting the peripheral wall of the vertical tube.

〔Example〕

 Hereinafter, the present invention will be described based on embodiments shown in the drawings.

FIG. 1 is a plan view of an apparatus for converting and transferring articles such as tablets in a horizontal direction from a rotary disk for sequentially and continuously transferring to a vertical tube, FIG. 2 is a sectional view thereof, and FIG. 3 is a perspective view of essential parts. is there.

In the figure, reference numeral 1 denotes a rotating disk which is driven at a constant speed or adjustable and has its upper surface formed into a flat surface or a conical surface.

By supplying the article G onto the rotating disk 1 from the supply position, the articles G are aligned in a row along the outer peripheral side plate 5 in the horizontal direction by the centrifugal force accompanying the rotation of the rotating disk 1, that is, the rotating disk 1 Is transferred in the direction of rotation.

Then, at the article take-out position of the rotary disc 1, the introduction guide 2 is provided in the vicinity of the upper surface of the rotary disc 1, and the article G transferred horizontally on the rotary disc 1 is guided along the introduction guide 2. He is transferred to the outside of the disk.

The introduction guide 2 is composed of a protruding portion 2a protruding above the rotating disk 1 and a cylindrical portion 2b continuous with the protruding portion 2a. The end of the cylindrical portion 2b is connected to the vertical pipe 3, and the article G is more than the rotating disk 1. It is sequentially transferred to the vertical pipe 3 side through the introduction guide 2.

The upper end of this vertical pipe 3 is open, and a pressure fluid blow-out pipe 4 is provided from above to the downward direction of the vertical pipe, and an article G guided from the rotary disk 1 through the introduction guide 2 into the vertical pipe 3 is introduced from above. The pressure fluid is pushed downward so as to be forcibly transferred, that is, the pressure fluid pressure is applied to the dropping force due to the weight of the article G to accelerate the falling speed.

In addition, the article G located in the cylindrical portion 2b of the introduction guide 2,
The suction force acts in the horizontal direction. This is an ejector effect when the pressure fluid is ejected from the pressure fluid discharge pipe 4 toward the vertical pipe 3, and the inside of the cylindrical portion 2b of the introduction guide 2 becomes negative pressure, which becomes a horizontal suction force. It gives G a horizontal acceleration force.

Therefore, the article G that is continuously fed to the introduction guide 2 is transported while changing the direction from the horizontal direction to the vertical direction at a high speed without causing a jam.

The pressure fluid ejected from the pressure fluid ejection pipe 4 presses the surface of the article G, and is then exhausted to the outside from the exhaust port 3a opened in the peripheral wall of the vertical pipe 3.

〔The invention's effect〕

According to the present invention, the downward pressure fluid ejected from the pressure fluid ejection pipe applies suction force to the article in the introduction guide by the ejector effect, and the self-weight in the vertical direction with respect to the article in the vertical tube. It is possible to give an accelerating force more than the drop force by the. As a result, the article is transferred from the introduction guide to the vertical pipe at high speed and smoothly, and the article can be efficiently processed.

Further, while the pressure fluid flows down in the vertical pipe, it is uniformly exhausted from a plurality of exhaust ports formed at substantially equal intervals in the circumferential direction of the peripheral wall of the vertical pipe. Without this, that is, the article is transported downward without contacting the peripheral wall of the vertical tube, and the article is smoothly moved horizontally, which has an advantage that the article being transported is not likely to be damaged.
