Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an apparatus for quantitatively supplying a granular or powdered powder.

[0002]

[Prior Art]

 It has been common practice to continuously supply a fixed amount of powdered powder into the hopper at regular intervals and package the powdered powder falling from the lower outlet of the hopper with a heat-fusible laminated paper. A metering device is provided to supply the powdered medicine to the hopper.

As a device for supplying a fixed amount of powdered medicine, a feeder for supplying powdered medicine is provided on a distribution tray which is rotationally driven in one direction, and the feeder is formed on the outer peripheral portion of the distribution tray while the distribution tray is rotated in one direction. A fixed amount of powdered medicine is continuously supplied into the annular groove formed, and after the powdered medicine is supplied, the distribution dish is rotated in the same manner as above to scrape out the powdered medicine that is uniformly deposited in the annular groove, and the periphery of the distribution dish is covered by a scraping device. It has been known from the past that a hopper provided in the hopper is scraped off in a fixed amount.

[0004]

[Problems to be solved by the device]

 By the way, in the above-mentioned fixed amount supply device, since the powdered medicine continuously falling from the feeder is deposited in the annular groove of the distribution dish, the powdered medicine may be piled up in a pile shape in the nature of the powdered medicine. There is an inconvenience that when the amount of the powdered medicine in the annular groove is scraped off by the dropping device in a fixed amount, the powdered powder collapses and the amount of the scraped out becomes uneven.

This invention eliminates the above-mentioned inconvenience, leveles the surface of the powdered medicine which is supplied to the annular groove of the distribution dish and accumulates, and aims to make the volume of the powdered medicine that is scraped out by the scraping device uniform. It is an issue.

[0006]

[Means for Solving the Problems] In order to solve the above-mentioned problems, in the present invention, in the above-mentioned fixed amount supply device for powdered medicine, the powder is supplied to the annular groove provided on the distribution tray. We adopted a structure in which a leveling member is provided to smooth the surface of the powdered medicine by contacting the surface of the powdered medicine.

[0007]

[Action]

 As described above, by providing the leveling member on the annular groove, when the powdered medicine supplied from the feeder to the annular groove accumulates in a mountain shape, the leveling member comes into contact with the surface of the powdered medicine, and the surface of the powdered medicine is leveled. be able to.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in the drawing, the distribution tray 1 has an annular shape, and an annular groove 2 is provided on the outer peripheral portion of the upper surface thereof, and the bottom surface of the annular groove 2 is an arc surface. An annular gear 3 is fixed to the lower surface of the distribution tray 1, a drive gear 5 driven by a motor 4 meshes with the gear 3, and the distribution tray 1 is rotated by driving the motor 4.

A vibrating feeder 10 is provided above the distribution tray 1 to continuously and quantitatively supply the powdered medicine to the annular groove 2. The feeder 10 has a hopper 11 and a chute 12 whose rear end faces the lower outlet of the hopper 11. The vibrating device 13 vibrates the chute 12 in the longitudinal direction, and the hopper 11 shoots the chute 12. The powder that drops upwards is continuously and quantitatively dropped from the tip of the chute 12 into the annular groove 2.

The powdered medicine supplied into the annular groove 2 is scraped off by a scraping device 20 into a hopper 30 provided around the distribution tray 1. The scraping device 20 is configured to rotate a rotor 21 provided to be movable up and down with respect to the annular groove 2 in a direction of an arrow in FIG. 1 by a drive device (not shown). The side surface is provided with a scraping plate 23, and the scraping plate 23 scrapes off the powdered medicine in the annular groove 2 to the hopper 30.

A support shaft 40 is provided around the distribution tray 1, and a support cylinder 41 is attached to the outside of the support shaft 40. The support cylinder 41 is attached by means such as screwing so as to adjust the height, and a leveling member 43 is attached to the support cylinder 41 via a leaf spring 42.

Here, the leveling member 43 may be a rod-shaped member as well as the plate-shaped member shown in the drawing. The leveling member 43 extends in the radial direction of the distribution dish 1, and its tip is located on the annular groove 2. Reference numeral 44 denotes a vibrator that applies vibration to the leveling member 43.

In the fixed-quantity supply device having the above-described configuration, the powdered medicine is supplied to the annular groove 2 by supplying a predetermined amount of the powdered medicine into the hopper 11 of the feeder 10 to operate the feeder 10, and at the same time the distribution tray 1 Rotate in the direction.

The powder medicine which is dropped from the hopper 11 onto the chute 12 by driving the feeder 10 moves toward the tip of the chute 12 and continuously drops from the tip of the chute 12 into the annular groove 2. At this time, since the distribution dish 1 is rotating in one direction, the powdered medicine is accumulated over the entire circumferential direction of the annular groove 2.

At this time, if the powder is powdery, the powder is piled up in the annular groove 2, and if the powder is left as it is, it collapses when the scraping device 20 scrapes out the powder. Occurs, and the amount of the powdered substance scraped out becomes uneven.

However, in this invention, since the leveling member 43 is provided on the annular groove 2, when the powdered medicine supplied on the annular groove 2 accumulates in a mountain shape, the surface of the powdered medicine becomes the above-mentioned leveling portion. It is leveled by the contact with the material 43, and the surface is made uniform.

Therefore, when the rotor 21 is lowered and the rotor 21 and the distribution dish 1 are rotated to scrape the powdered medicine in the annular groove 2 into the hopper 30, the powdered medicine scraped out by the scraping plate 23 of the rotor 21. It is possible to continuously scrape out a fixed amount of powdered medicine into the hopper 30 by the rotor 21 without the collapse of the powder.

When the powder medicine is leveled by the leveling member 43, the powder level may be attached to the leveling member 43. Therefore, the vibrator 44 is actuated to vibrate the leveling member 43 to prevent the powder level from being attached. .

[0020]

[Effect of the device]

 As described above, in the device for quantitatively supplying the powdered medicine according to the present invention, the leveling member provided on the annular groove smoothes the surface of the powdered medicine supplied on the annular groove, so that the powdered medicine is scraped out by the scraping device. The volume of powdered medicine can be made uniform.
