CONSTITUTION:A material to be fed 2 consisting of an ingredient such as 'shao-mai' charged into hopper 1 is fed toward a delivery port 1a as follows: when a rod 7a in an air cylinder 7 is made to descend, both semilunar plates 3a, 3a of push-feeding pieces 3 closed at the lower end of a shaft 4 are allowed to descend while being opened to both sides with a pin as a support through the resistance of the in-hopper material 2, thereby feeding said material 2. Thence, when the rod 7a is raised, another batch of a material to be fed 2 is allowed to ascend smoothly to a specified position while closing the above semilunar plates 3a, 3a being in an opened state. Next, in this state, the shaft 4 is made to descend again, thus, automatically, continuously repeating operations similar to those mentioned above.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention is mainly directed to a feeding device for food, and more specifically, toppings such as shumai, gyoza, etc., cream, jam, or sweet bean paste that are fed into a hopper above a filling machine. This invention relates to a feeding device suitable for smoothly feeding the so-called paste product to a filling machine below.

Conventionally, in this type of hopper, the means for sending the input material to the filling machine connected below the hopper is to suspend a screw in the center of the hopper, and use a rotary drive connected above to drive the screw. A method was adopted in which the material inside the hopper was forcibly sent downward while being rotated by a mechanism.

C1 Problems to be Solved by the Invention However, such a system using a screw has various drawbacks as described below.

That is, since the rotational force of the screw is utilized, the input materials tend to overflow, and there is a risk that the materials will be kneaded more than necessary.

As a result, for example, when the input material is an ingredient such as shumai or gyoza, the moisture (juice) contained in the ingredient drips out, resulting in a deterioration in taste.

In addition, only the input material located at the center of the hopper was supplied to the filling machine below, and the outer portion tended to remain in the hopper.

Furthermore, there is a drawback that the materials contained in the input materials, such as the vegetables contained in the ingredients, the chopped pieces of fruit contained in cream, jam, etc., or the green peas contained in green bean paste, are crushed or crushed.

The present invention has been made in view of the above-mentioned drawbacks, and is a feeding device that can push out the material to be fed into the hopper with the palm of its hand without kneading it, and send it to the supply port below. It provides:

2. Means for solving the above-mentioned problems The means of the present invention for achieving the above-mentioned objects is such that a shaft connected to an elevating mechanism is suspended above the delivery port below the hopper so as to be able to rise and fall freely, and the hopper is attached to the shaft. It is equipped with a hinge-type pushing piece that can be opened and closed to send out the objects inside to the outlet below.

6. When the object 2, such as shumai and dumplings, is put into the hopper 1 and the rod 7a of the air cylinder 7, which serves as a lifting mechanism, is lowered, the lower end of the shaft 4 is in the closed state shown by the solid line in Fig. 4. Both meniscuses 3a, 3a of the pushing piece 3 descend while opening laterally using the pin 10 as a fulcrum due to the resistance of the object 2 in the hopper 1, and send out the object 2 toward the outlet 1a.

At this time, both menisci 3a, 3a are locked and fixed to the lower edge of the shaft 4 in a state of being opened 90 degrees as shown in FIG. do not have.

Next, when the rod 7a of the air cylinder 7 is raised, both menisci 3a, 3 of the pushing piece 3, which is in the open state as described above, are lifted.
a smoothly rises to a predetermined position while closing with the pin 10 as a fulcrum due to the resistance of the transported object 2.

In this state, the shaft 4 descends again, and the same operation is repeated automatically and continuously.

Further, as shown in Fig. 5.6, two pushing pieces 13, 13 are attached to the upper and lower sides of the shaft 4, as described above.

That is, as the rod 7a descends, each pushing piece 13.13
The rectangular plates 13a, 13a open simultaneously using the pin 10 as a fulcrum to push the object 2 in the hopper 1 into two pieces 13.
13 to send it out toward the outlet 1a.

Next, as the rod 7a rises, the upper and lower rectangular plates 13a
, 13a are simultaneously closed and smoothly raised to a predetermined position.

Thereafter, similar operations are repeated.

To, Example Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

Figures 1 to 4 show a first example of implementing the present invention, and the hopper 1 is made of a material that does not have a chemical effect on the objects 2 such as shumai and gyoza ingredients, such as stainless steel with a Teflon coating on the inner surface. A shaft 4, on which a hinge-type pushing piece 3 is attached so as to be openable and closable, is vertically suspended at the center above the outlet 1a, which is formed of a steel plate into an inverted conical shape and is open at the lower center.

By inserting a long pin 10 into the tube, it is hinged to the lower end of the shaft 4 so as to be openable and closable.

Therefore, when the rod 7a of the air cylinder 7 descends, both menisci 3a, 3a of the pushing piece 3 attached to the lower end of the shaft 4 are moved by the resistance of the object 2 thrown into the hopper as shown in FIG. The opening angle of the pushing piece 3 is equal to that of each meniscus 3a.
, 3a are locked to the lower end line 4a of the shaft 4 and stop at exactly 90 degrees as shown.

Next, when the rod 7a of the air cylinder 7 rises, both menisci 3a, 3a of the pushing piece 3 return to the state shown by the solid line in FIG. 4 due to the resistance of the object 2 in the opposite direction and close.

Note that a spring (not shown) may be used to smoothly open and close the pushing piece 3.

In addition, the lifting speed of the rod 7a of the air cylinder 7 can be automatically controlled according to the viscosity and amount of the transported object 2. In addition, in 1), when the meniscus 3a opens and descends, the Although the hole is for reducing the resistance of the object 2, a plurality of notches (not shown) may be provided at the outer edge.

Next, FIGS. 5 to 10 show a second example of carrying out the present invention, in which a connecting pipe 9 is held and fixed to the lower end of the shaft 4, and a connecting pipe 9 is also attached to the substantially interrupted portion of the shaft 4 above the connecting pipe 9. is fixed through the connecting pipes 9 and 12, and pushing pieces 13 and 13 are respectively attached to both connecting pipes 9 and 12 in two stages.

By inserting a long pin 10 into the container tube with the shaft 2 arranged in a straight line, the shaft 4 is hinged at the lower end of the shaft 4 and above the shaft 4 so as to be openable and closable.

As a result, each pushing piece 13, 13 opens and closes due to the resistance of the object 2 thrown into the hopper, as in the first embodiment. Further, in this embodiment, a plurality of notches 14 are provided at the outer edge of each rectangular plate 13a, 13a in order to reduce the resistance of the object 2, but holes may be made as in the first embodiment. In addition, in the figure, 15 is a notch for penetrating the shaft 4 provided at the center of the inside of the rectangular plates 13a, 13a attached to the middle side of the shaft 4, and 15 is a notch for the upper pushing piece 13 to
A stop protrusion provided on the shaft 4 to prevent it from opening more than 1 degree.
7 is a notch into which the tip of the pushing piece 13 enters when it is closed.

By the way, in the above embodiment, the number of pushing pieces 3, 13 is up to two, and the shapes are only circular and rectangular, but it is needless to say that they are not limited to these, and can be changed at any time depending on the size and shape of the hopper 1. It is changeable.

1. Effects of the Invention As described above, the feeding device according to the present invention has a shaft 4 connected to an elevating mechanism 5 suspended above the outlet 1a below the hopper 1 so as to be able to rise and fall freely, and the hopper 1 A hinge-type pushing piece 3.13 that sends out the object 2 inside toward the delivery port 1a below is attached so as to be openable and closable, and the shaft 4
When the shaft 4 descends, each pushing piece 3.13 opens automatically due to the resistance of the object 2, and when the shaft 4 rises, each pushing piece 3.13 automatically closes due to the resistance of the object 2. Because of this, the movement of the shaft 4 to move up is extremely smooth, and the structure is simple, so that not only the product cost but also the power cost can be reduced.

Moreover, each pushing piece 3.13 does not rotate.

Since the product 2 is sent out in a straight line as if it were pressed with the palm of a hand, there are no inconveniences caused by kneading the product 2 more than necessary, such as water (juice) contained in the product 2 dripping out and deteriorating the taste. This completely eliminates drawbacks such as crushing or crushing of granular solids.
