にする。[0005] Such high-speed rotation of the diameter-enlarging screw portion pushes the powdery material in the hopper radially outward of the hopper and hinders the smooth introduction of the powdery material into the groove of the diameter-enlarging screw portion. I do. For this reason, the filling rate of the granular material in the funnel, that is, the cylindrical screw part side is reduced, and the apparent discharge amount of the granular material defined by the rotation of the auger screw is actually reduced from the discharge port of the funnel. The actual discharge amount of the granular material discharged to the nozzle becomes small. This means that the discharge efficiency of the filling device is reduced, and it is difficult to increase the speed and to perform the fixed filling.

Is discharged, and the granular material is filled in a container A positioned below the funnel 2. When the container A is filled with the predetermined amount of the granular material, the rotation of the auger 10 is stopped, and the discharge of the granular material from the discharge port 24 is immediately stopped. That is, when the rotation of the auger 10 is stopped, the discharge pressure in the vicinity of the discharge port 24 is reduced, so that the granular material is arched between the outer peripheral edge of the drip 20 and the inner peripheral edge of the nozzle ring 18. Is formed, and the discharge is stopped by such a bridge of the granular material.

いる。As is clear from FIG. 1, the container A is arranged on a conveying surface 48 such as a belt conveyor. When the filling of the container A with the powder is completed, the empty container A is then replaced with a funnel. 2 and the filling process of the granular material is repeated. As described above, the filling process of the granular material into each container A is defined by a period during which the auger 10 is operating and a stop period, and the period is indicated by T in FIG.

ガ１０の円筒スクリュー部１２側に確実に送込まれる。However, as is apparent from FIG. 4, when the operation of the filling device is started, the agitator rod 40 and the rake blade 42 always rotate at a constant speed in a direction opposite to the rotation direction of the auger 10, Here, the turning speed is lower than the rotation speed of the auger 10. According to the above-described filling device, since the predetermined gap G is secured between the upper end of the enlarged screw portion 14 of the auger 10 and the inner peripheral surface of the hopper 4, the auger 10, ie, the enlarged screw portion 14 of the auger 10 is secured. Even if the rotation speed is increased, the granular material in the hopper 4 is not hindered by the peripheral speed at the upper end of the diameter-enlarging screw portion 14,
It intrudes into the groove of the enlarged diameter screw section 14 through the annular flow path 26. On the other hand, since the passage width of the annular passage 26 is constant along the inner peripheral surface of the hopper 4 or is gradually reduced toward the cylindrical screw portion 12, the diameter of the enlarged screw portion 14 is reduced.
The granular material that has intruded into the groove cannot escape radially outward due to the high-speed rotation of the diameter-enlarging screw portion 14, and therefore, the intruded particle material cannot be removed by the screw fins in the diameter-enlarging screw portion 14. Is effectively pressed by the rotation of the auger 10 and reliably sent to the cylindrical screw portion 12 side of the auger 10.

制的に押込まれる。On the other hand, during rotation of the auger 10, the agitator rod 40 and the rake blade 42 rotate in the opposite directions, so that the rotation of the agitator rod 40 is To guide the powder in the hopper 4 through the gap G and smoothly into the groove of the enlarged screw portion 14. Also,
In the swirling blade 42, when viewed in the turning direction, the curvature of the upper portion on the trailing edge side is larger than the curvature of the lower portion thereof. The granular material that flows in the vertical direction is raked toward the center of the diameter-enlarging screw portion 14 as shown by the white arrow in FIG. As a result, the granular material guided into the groove of the diameter-enlargement screw portion 14 through the gap G is forcibly pushed into the diameter-increase screw portion 14 by the action of the raking blade 42.

The pressing of the granular material by the screw fins in the diameter screw portion 14 is assured, and
The feeding of the granular material from the cylindrical screw portion 12 to the cylindrical screw portion 12 is stabilized, and the filling rate of the granular material in the cylindrical screw portion 12, that is, the funnel 2 can be improved.
