Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a polishing device for fruits, vegetables, etc.

Conventionally, devices for polishing fruits and vegetables, such as mandarin oranges, by rolling them on rollers have been equipped with a number of rollers with spiral grooves formed on their circumferential surfaces made of horsehair, which are rotated, and the mandarin oranges are placed on top of the rollers. There was a structure in which polishing or waxing was performed while rolling, but the residence time of mandarin oranges on the roller was short, but the rolling efficiency was also poor, making it difficult to perform a complete polishing action.

In the present invention, a large number of rollers with uneven circumferential surfaces are installed at regular intervals between the machine frames, and the rollers are rotated to transport fruits, etc. placed on each roller. Furthermore, the circumferential speed of each roller is increased in order in the conveyance direction, and
The present invention provides a polishing device for fruits, vegetables, etc., characterized in that each roller is arranged in an upward slope toward the conveyance direction.

Detailing the embodiment of the present invention based on the drawings, 1 and 1' are machine frames, which are arranged with a constant interval left and right, and a large number of rollers 2 are arranged adjacently between them. , the roller 2 is made of a surface porous elastic material, for example,
A sponge with a porous surface is used, and an uneven shape a is formed on the circumferential surface. The uneven shape a is formed by not only arbitrarily providing unevenness but also by overlapping a large number of rectangular or longitudinal hexagonal members and partially shifting them from each other so that the protruding protrusions become spiral. An integrally molded one is used (see Figures 3 and 4).

A large number of the rollers 2 described above have the same shape and are installed rotatably between the machine frames 1 and 1' adjacent to each other, and a chain 5 is influenced and meshed with a sprocket 4 provided on the shaft 3 of each roller 2. At least, each roller 2 is configured to rotate in the conveyance direction and to gradually increase its circumferential speed.

Note that the gradual acceleration structure of the circumferential speed is based on sprocket 4.
It is adjusted depending on the size of

6 is a rolling wheel for tensioning the chain.

Note that a roller group M in which a large number of rollers 2 are adjacent to each other is
It is sloped gradually upward in the direction of conveyance, and a required number of roller groups M are connected, and a step is formed at the boundary between each roller group M, and an inclined plate 7 is interposed at the step. ing.

In addition, the circumferential speed of each roller 2 in the roller group M can be gradually decelerated in addition to the meshing that gradually accelerates, and furthermore, the circumferential speed of each roller 2 in the roller group M can be gradually accelerated by having different circumferential bundles of adjacent rollers.・It is also possible not to have a deceleration configuration.

n indicates tangerine, and 8 indicates a waxy oil nozzle.

The embodiment of the present invention is configured as described above, and from the end of the roller group M, the tangerine n
If a large number of rollers 2 are mounted, the uneven shape a on the circumferential surface of the roller 2 of the roller group M will face each other at a different angle each rotation due to the difference in circumferential speed with the adjacent roller, and the circumference of the orange It contacts the surface from various angles, and due to the slope of the roller group M, it rotates in an uneven shape a due to the weight of the oranges, and is pushed by the oranges being conveyed from behind and sequentially rolls forward. Moreover, since the roller 2 is made of an elastic material with a porous surface, contact with the surface of the tangerine can be made flexibly, and the surface polishing function is also improved. Due to the stepped inclined plate 7 formed at the boundary, the mandarin oranges are smoothly transported to the roller group for the next process, and even if waxing oil is applied to the roller group for the subsequent process, the wax will not be applied. ,
It does not flow back into the roller group in the previous process.

According to this invention, an uneven shape is formed on the circumferential surface of the roller made of a surface-porous elastic material, and furthermore,
Since the circumferential speeds of the adjacent rollers are different, the unevenness of the circumferential surfaces of the adjacent rollers face each other at different angles with each rotation, which promotes rolling of fruits, vegetables, etc. The residence time on the roller can be long, the conveyance efficiency is good, and a sufficient polishing action can be performed.
