Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hair removal device for bagging food materials, particularly powder or granular materials.

[Prior Art] Naturally, it is necessary to avoid hair from getting mixed into food materials, but when powdered or granular food materials are packed into bags using a hopper, sometimes hair gets mixed into the food materials. Conventionally, there was no suitable method for removing hair in such cases, and the only way to remove the hair was by visual inspection.

[Problems to be Solved by the Invention] With such a method of visually selecting and removing hair, it is almost impossible to remove hair from granular materials.

Therefore, an object of the present invention is to provide a hair removal device that can automatically remove hair by utilizing the fact that hair is attached by static electricity.

[Means for Solving the Problems] The hair removal device according to the present invention is installed on the outer surface of the chute of a hopper for feeding food materials, and a charged rotating body in the form of a roller or conveyor is installed on the outer surface of the chute of a hopper for feeding food materials. It is designed to rotate while in contact with the outer surface.

[Function] In the hair removal device according to the present invention, when powder or granular food material is passed from the input hopper through the chute and packed into bags, the charged rotating body is brought into contact with the outer surface of the chute. By rotating, the inner surface of the chute is charged with static electricity. Therefore, hair mixed in the food material adheres to the inner surface of the chute and is automatically removed.

[Example] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. As shown in FIG. 1, a chute 4 made of a metal plate is provided in a hopper 2 for feeding powder or granular food material 1 through an insulator 3, and the lower end of this chute 4 is connected to an insulator 5. It is inserted into the bag 6 through. A pair of left and right charged rotating bodies 7 are installed so as to be in contact with the outer surface of the chute 4 and rotate, sandwiching the chute 4 therebetween. This charged rotating body 7 is composed of a metal roller 9 whose roller shaft 8 is grounded, and an insulating film 10 adhered to the surface of this roller 9.

This embodiment is configured as described above,
Next, to explain its operation, food material 1 in the form of powder or granules is charged from the input hopper 2 through the chute 4 into the bag 6 at the lower end. Since the charged rotating body 7 is rotating in contact with the outer surface of the chute 4, static electricity is generated on the inner surface of the chute 4, which is a metal plate. Therefore, the hair mixed in the food material 1 is separated from the food material 1 and attached to the inner surface of the chute 4 due to this static electricity. In this way, food material 1
The hair is automatically separated and removed. In this embodiment, the charged rotating body 7 is placed outside the chute 4.
Although they are provided in pairs, the number and arrangement relationship can be changed freely. Further, although the chute 4 is shown as being linear, it is convenient to form it into a gentle spiral shape.

Next, FIG. 2 is a configuration diagram showing another embodiment of the present invention, in which each charged rotating body 7a is a belt conveyor type consisting of cloth wound between a ground roller 11 and a driven roller 12. It is composed of
Then, the charging roller 13 is connected to the grounding roller 11.
are arranged as close as possible to each other, the cloth on the grounding roller 11, that is, the charged carrier 7a, is charged with static electricity, and this static electricity is transmitted to the inner surface of the chute 4, which the charged rotating body 7a contacts and rotates. Further, it is preferable to provide a plurality of pressing rollers 14 in order to equalize the state of contact between the charged rotating body 7a, which is cloth, and the chute 4. In addition, in the figure, 15 is a storage battery for applying electric charge to the charging roller 13. The other configurations are the same as those of the above embodiment.

In this embodiment, since the charging range of the charged rotary body 7a is longer than that of the above-mentioned embodiment, there is an advantage that even if the chute 4 is linear, hair can be removed more reliably.

Note that in this embodiment, the charging roller 13
was set to have a positive charge, and the ground roller 11 was set to have a negative charge,
These polarities can also be reversed. Also,
The electric polarities of the left and right charged carriers 7a may be reversed. As the electrostatic generator, for example, a Vandegraaf generator, an FFD (Electro-fluid Dynamic) generator, etc. can also be used.

[Effects of the invention] As described above, according to the invention, hair mixed in powder or granular food materials can be automatically removed when bagging them.
It's extremely convenient.
