[Conventional technology]

As the above food supply device, for example, Jikosho
60-16481 has already been provided. In this method, the inner wall of a flow hole in which an upper shutter and a lower shutter are connected to a hopper is formed by a jet cylinder having a large number of air jet holes.
The lower shutter is closed, the upper shutter is opened, a predetermined amount of food is collected from inside the hopper onto the lower shutter, the upper shutter is closed, the lower shutter is opened, and at the same time the air is directed from the air jet hole to the center of the distribution hole. Air is ejected to blow away the food that adheres to the filling container placed below.

[Problems that this invention attempts to solve]

However, in the above-mentioned device, the air ejected from the air ejection hole of the ejection cylinder collides at the center of the distribution hole, and the airflow that momentarily becomes turbulent blows below the distribution hole. While it is often blown down, the wind pressure often causes containers placed below to tilt or become misaligned. Particularly, when filling a plastic bag or the like, a configuration is required that allows the opening of the bag to be expanded against the wind pressure.

[Means for solving problems]

This project attempts to solve all of the above problems, and includes a rotating drum that has screw blades in the rear chamber, blades in the front chamber, and is fixed to a rotating shaft. A guiding plate inserted into the rear notch of the rotating drum, a rotating cylinder installed in front of the rotating drum with a gear that meshes with the rack of the rotating air cylinder, and a key locked to this rotating cylinder so that it can be moved freely. The operating rod is inserted into the rotary drum and has a measuring cup fixed to its tip.The operating rod is connected to an air cylinder, and the measuring cup is inserted into the inside of the rotary drum through the front notch and returned to the rotary drum. It is characterized by a structure in which it is rotated downward by a cylinder and then returned to its original position.

[Effect]

For convenience of explanation, the operation of the present device having the above-mentioned configuration will be explained based on the drawings of the embodiment and with reference to the reference numerals.

In this device, the motor 9 is driven to rotate the rotating drum 4 via the rotating shaft 3.

On the other hand, the filled food is sent to the guide plate 11 from a hopper (not shown) and falls into the rear chamber of the rotary drum 4 through the guide plate 11 which is tilted downward. On this occasion,
When the air cylinder or solenoid 15 is operated intermittently, the guide plate 11 is moved up and down and swung around the pivot point, so that the filled food does not accumulate on the guide plate.

The filled food that has entered the rear cavity of the rotating drum 4 is
It is fed into the front cavity through the gap between the arms 5 by the screw blades 6, and is successively scooped up by the blades 7 and ascends, and then falls by the rotation of the blades.

At this time, the air cylinder 22 is pulled and the operating rod 20 and therefore the measuring cup 21 enter the front cavity and catch the falling food product.
In this case, the stop position of the measuring cup 21 is set slightly closer to the rotating upward side of the drum 4 from the axial center line of the rotary shaft 3, so that the falling filled food can be well received.

Next, the air cylinder 22 operates to push out and return the operating rod 20 and the lightweight cup 21 to their previous positions, and then the rotating air cylinder 25 operates to push out the rack 26, which engages the gear 24.
The rotary cylinder 19 having the
0. The measuring cup 21 is also rotated inverted and the filled food is put into the guide tube 27.

At the same time, the insertion tube 29 rises and immediately descends, inserting its lower part into the bag 31 held by the transfer body 30 and dropping the filled food.
Repeat the above operation.
