Abstract

PURPOSE:To shorten a drop distance of powdery and granular materials to enable rapid filling to be carried out by providing a constant quantity supply part of a filling apparatus for powdery and granular materials and a filling part below it, and driving an intermediate chute which reciprocates at a certain cycle to carry the materials between the above two parts. CONSTITUTION:Medicine powder is packed from a hopper into each measure 111 by a subdivision amount by a fixed leveling plate 112 along with a rotation of a measuring rotation disk 110 of a supply part and subdivision-packed into intermediate moving chutes 12, 13 below the measure 11 by opening of a shutter 115. A wrapping film pulled out from a reel is bent into a cylinder and appropriately cut by a cutter. A filling apparatus reciprocates the intermediate moving chutes 12, 13 between respective fixed guide chutes 11, 11 and a filling part of a film guide also serving as a throw-in chute 120. Since this is provided at an intermediate height position between the measuring rotation disk 110 and the filling part 130, a drop distance (h) of the powder from the chutes 12, 13 into the cylindrical film is largely reduced, thereby reducing stir of the powder and improving filling speed.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powdery or granular material filling device for packaging powdery or granular material such as drug powder into a heat-welding film in predetermined amounts.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5 and FIG. 6, for example, a measuring turntable 1 which receives an appropriate supply of chemical powder from a hopper.
10 is a measuring container 1 provided around the periphery of the measuring container 1 at equal intervals.
The powder is divided into fixed amounts by a fixed scraping plate 112 while the metering turntable 110 is rotating, and a shutter 115 is provided above the filling chute 120.
Is opened and a certain amount of powder is shot from the measuring container 111 to the shoot 1.
I am trying to fall into 20.

The film is supplied from the upper side to the lower side, formed into a tube shape along the film guide portion 121 of the chute 120, processed into a tube by the vertical heat sealer 131, and divided by the horizontal heat sealer 132. There is a limit to bringing the weighing container 111 close to the filling unit 130, and the inclination of the chute 120 needs to be increased to some extent in order to ensure smooth sliding down. The (falling distance of the object to be filled) H was quite large.

[0004]

In the above-mentioned conventional structure, since the drop between the weighing container 111 and the filling section 130 is large, the powder that has fallen has a large rise and takes a long time to settle, and the weighing is performed. The lump of the powder supplied to the chute 120 after being ground by the grinding plate 112 by rotating the rotating plate 110 directly falls to the inlet of the filling unit 130, and as shown in FIG. Due to the inertial force at the time of falling from the chute 120, the chute 120 is divided into those that reflect and fall to the side wall of the chute 120, and there is a difference in the falling time of both, resulting in a longer filling time. If the mass of the powder that has dropped directly to the inlet of the filling unit 130 is larger than the width of the inlet, it becomes difficult to pass through the inside of the filling unit 130, which causes the filling time to be long. In addition, the powder that has flown up to the heat-sealed portion of the film may be caught in the horizontal heat sealer 132 and cause an incomplete sealed state.

The present invention has been devised in view of the above, and has a shape in which the fall distance of the powder to the filling portion is shortened to prevent the powder from rising and delayed falling, so that the powder can easily pass through the inside of the filling portion 130 in advance. It is an object of the present invention to provide a powdery or granular material filling device that can be dropped at high speed to enable high-speed filling and complete sealing.

[0006]

In order to achieve the above object, a powder / granule filling apparatus according to the present invention comprises a powder / granule constant-quantity supply unit and a powder / granular body provided below the supply unit. And the filling section of
An intermediate chute that alternately reciprocates between the supply unit and the filling unit in a constant cycle to convey the powder or granular material received from the supply unit to the filling unit, and a reciprocating drive mechanism for these intermediate chutes. It is characterized by that.

First, the filling and packaging machine 1 according to the present invention will be briefly described with reference to FIG. The same parts as those of the conventional example are designated by the same reference numerals. The medicinal powder is supplied from the hopper 2 onto the weighing rotary disc 110 for weighing which constitutes a fixed amount supply unit, and is put into each weighing container 111 by the fixed scraping plate 112 as the weighing rotary disc 110 rotates. Volume 1
An opening / closing shutter 115 is provided at the lower opening of the shutter 11, and the shutter 115 is opened when the powder supplying portion to the intermediate moving chutes 12 and 13 below is reached. The powder supply section has a rotating measuring container 11
Fixed guide chutes 11 and 11 are provided in order to reliably transfer the powder from 1 to the reciprocating chutes 12 and 13.

On the other hand, the wrapping film F is pulled out from the reel R, curved in a tubular shape at the guide portion 121 of the film guide / feed chute 120, and then the vertical sealer 13 is inserted.
1 is processed into a cylinder, divided by a horizontal sealer 132, and after being filled with powder, it is appropriately cut by a cutter 140.

As shown in FIGS. 2, 3 and 4, the filling device 10 moves between the fixed guide chutes 11, 11 and the filling portion 130 of the film guide / feeding chute 120, and moves the chute 12 ,. A reciprocating mechanism 15 for reciprocating 13 is provided. The reciprocating mechanism 15 includes a large gear 15 that reciprocally rotates as indicated by an arrow X by a crank mechanism 15a.

The chute 12 is guided by reciprocating in a V shape toward 0,
The fixed guide chutes 11 and 11 and linear ways 17a and 17a that reciprocate between the filling section 130 are provided.

On the moving carriage 16b, the chutes 12, 1 are provided.
A shutter 16c for controlling the opening and closing of the lower opening of No. 3 is provided in a state of being biased in the closing direction by a spring 16d, and the truck 16b on the right side (the lower side of FIG. 4) is moved back to inherit the chute 12. The shutter 16c is closed at a position directly below the chute 11. Further, the truck 16b on the left side (upper side in FIG. 4) is moved forward to the filling section 130 to expose the chute 13 to the filling section 130, and the shutter 16c hits the stopper 17b at the tip of the linear way 17a in front of the chute 13. The lower opening of is open. The opening / closing position of the shutter 16c is adjusted by an adjusting bolt 16e that abuts on the stopper 17b.

Thus, the intermediate moving chutes 12 and 13 are provided at a height intermediate position between the metering turntable 110 of the supply unit and the filling unit 130 to drop the powder from the chutes 12 and 13 into the tubular film. Since h is significantly shortened and the powder rise is reduced, and the powder is conveyed by the chutes 12 and 13 which are alternately driven back and forth, the filling speed can be increased by 150% or more. . Further, by moving the chutes 12 and 13 horizontally, the position of dropping the powder and granules can be brought closer to the filling unit 130, so that the shapes of the chutes 12 and 13 can be optimized, and the powder can easily pass through the filling unit 130. It enables smooth filling.
