Description

DETAILED DESCRIPTION OF THE INVENTION The great invention in the field of industrial application relates to an apparatus for feeding pharmaceutical products such as tablets and capsules one by one to a packaging machine or an inspection machine at a reliable number ζ and at high speed.

Conventional technology and its problems Pharmaceutical drugs such as tablets and capsules are continuously supplied one tablet at a time from a manufacturing machine to an inspection machine and a packaging machine for inspection, packaging, etc.

When continuously supplying these articles, it is necessary to align the directions of the articles and to feed them at high speed according to the capabilities of the inspection machine and packaging machine. Conventional methods for supplying such articles include a method in which the article is fed through a pipe-shaped supply tube by a falling blade due to its own weight, or a method in which the article is forcibly pushed out one by one using a C iron such as a pusher. However, in this natural fall method, the feeding speed is limited by the weight of the article, its shape, frictional resistance with the supply pipe, etc., and it is difficult to achieve a high speed. It may also damage the product number. Furthermore, mechanical extrusion requires a complicated extrusion mechanism and may cause damage to the product.

It has the disadvantage of being damaged.

Solution to problem This great invention was made in view of this.

Circumferential surface or plane of a disk or packaging film or flat plate 1
In this device, articles are supplied one by one to the pockets formed at a predetermined pitch through a supply pipe disposed on the disk and having a lower end opening facing the pockets. In this process, an air jet hole is bored on the outer periphery of a part of a supply pipe that stores a large number of articles in a row, and pressurized fluid is supplied to this air jet hole, and the pressure fluid jetted into the pipe absorbs the weight of the articles. The falling speed is increased by adding pressure fluid pressure to the falling speed. By supplying pressurized air in the middle of this supply pipe, the ejector action works, sucking up the upper part of the supply pipe, and applying acceleration due to the compressed air to the lower part of the supply pipe. Alternatively, the speed of supply to a pocket formed in a flat film plate or the like can be increased, and the compressed air acts as a cushion so that the product can be supplied without damaging or damaging the product.

Example The present invention will be explained below based on the drawings.

In the figure, reference numeral 1 denotes a rotating disk which is driven at a constant or adjustable speed and has a flat or conical top surface, and when the tablet G is fed from the feeding position, the tablet is transferred to the outer peripheral side plate 51 of the rotating disk. They are scraped, arranged in a line, and transferred in the horizontal direction, that is, in the direction of rotation of the disk. At the article take-out position 1 of this rotary disk, an introduction guide 2 is provided close to the top surface of the disk, and the tablets G, which are supported on the top surface of the disk and are transferred in the horizontal direction by the rotation thereof, are placed here. It comes into contact with the introduction guide 2 and is then guided along this introduction guide and transported in the horizontal direction. The end of this introduction guide is guided into a supply pipe 8 which is close to the rotating disk, so that one tablet is naturally transferred from the rotating disk to this supply pipe. The upper part of this supply pipe B is open, and a compressed air blowing pipe 4 is provided from above to the lower side of the supply pipe, and the tablets introduced into the supply pipe from the one-rotation disk via the introduction guide are pressurized with compressed air from the upper part. Make sure to add . As a result, the tablets that have passed through the introduction guide and have reached the upper part of the supply pipe are forcibly pushed downwards. In other words, this pneumatic pressure is applied to the falling blade due to the tablet's own weight, accelerating the falling speed and pushing it upwards into the introduction guide. A suction force acts horizontally on the first tablet that is transferred horizontally. This is because the ejector effect when compressed air is injected from the compressed air blow-off pipe 4 creates a negative pressure in the introduction guide section, which becomes a horizontal suction force and gives a horizontal acceleration force to the tablet. Therefore, the tablet can be transferred at high speed while changing its direction from horizontal to vertical.

Further, the compressed air ejected from the compressed air blow-out tube presses the tablet surface and is then exhausted to the outside through an opening at the top of the supply tube or an exhaust port 8λ opened at the side surface of the tube.

Further, a small hole, that is, an air ejection hole, is bored diagonally downward on the outer periphery of the center or lower part of the supply pipe 8.

An air supply pipe 5 is provided to supply pressurized air from the outside. The lower end of this supply pipe 8 is open and faces the disk 6 which has a pocket on its circumferential surface or plane. This disk 6
Pocket 8 shaped to fit items such as value agents one by one
A is arranged in multiple stages at a partial pitch, and is rotated at a constant speed or variably, so that articles are sequentially and continuously supplied to the pockets of the disc from a supply pipe.

In the Naoki embodiment, the compressed air blowout pipe 4 is provided above the supply pipe 8,
The synergistic effect of this compressed air blow-off pipe and the air blow-off hole provided below the supply pipe allows the article to flow down the supply pipe at high speed, but the compressed air blow-off pipe is omitted. There is also a type that uses only the air outlet 7.

Furthermore, there are cases in which a pocketed product formed on a flat plate or packaging film is directly fed from a supply pipe without using a disk, and in this case, the flat plate or film is transported at a constant speed.

Effects of the Invention According to the present invention, articles are piled up in a line and compressed air is supplied into the supply pipe through which the pipe is inserted. For goods.

As the pressing force is applied to increase the acceleration chamber, the ejector action applies a downward suction force (h) to the article above the compressed air jet hole, and the entire inside of the supply pipe is prevented from falling ( (downstream) speed, and can be smoothly supplied to the pockets of disks rotating at high speed.

Furthermore, even when the rotation of the disk is stopped, no external mechanical force is applied to the article, so there is no chance of damage to the article. Therefore, the present invention is effective as a device that needs to supply the paste at regular intervals and at high speed in a device that continuously supplies the paste agent and the like to a packaging machine or an inspection machine.
