Abstract

PURPOSE:To peel completely garlics, etc. without damaging the surface of scale, etc., by forming unevenness of spirals having small angles of inclination on the surfaces of a pair of rollers, reversing the directions of the spirals of opposing rollers, differentiating the peripheral speeds of rollers. CONSTITUTION:The elastic body 2 such as rubber, etc. is attached to the surfaces of a pair of the rollers 1 and 1', unevenness having cushioning properties are formed on the surfaces. Scales of garlics covered with skin are put in the bank of the rollers, and epidermis is removed while they are passed through the rollers. The unevenness on the surfaces of the rollers 1 and 1' has the spiral shapes 1c and 1c' with small angles of inclination on the whole, the directions of the spirals of the opposing rollers are reversed, and the peripheral speeds of the rollers are differentiated. By the spirals, epidermis of the scales, etc. is subjected to release action by tensile strength. They are kept on a pair of the rollers while being transferred in the shaft direction, discharged downward in a completely peeled state, so that peeling of epidermis can be attained without damaging scales.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roller-type peeling device for mechanically removing the epidermis of onions, garlic, etc.

This type of roller-type peeling device has a pair of rollers with an elastic material such as rubber attached to the surface to form cushioning unevenness on the surface. There is a known method in which a pen is inserted and the skin is removed while the pen passes through the rollers. However, if you simply form unevenness and randomly roll the rings with a pair of rollers, no tensile or compressive force will be applied to the epidermis, and it will not peel properly. If the frictional force is increased, the cylindrical ring, whose skin has already been removed, will be scratched when passing between the rollers, which will cause rotting thereafter. Since then, various improvements have been made to the shape of the roller surface, but a peeling device that can almost completely peel the skin without damaging the surface of the paper has yet to be realized. The present invention has been developed based on the above-mentioned circumstances, in which a tensile force acts on the surface of the linpen, etc. in the axial direction of the pair of rollers, and the linpen is rolled while giving a peeling effect on the epidermis. The object of the present invention is to provide a roller-type peeling device that allows the skin to pass between the rollers without causing scratches on the surface due to the gap between the rollers increasing during the guidance process.

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings. In the figure, reference numeral 1.1' indicates a roller, and drive shafts 1b and 1 are located at the center of roller core bodies 1a and la', respectively.
b' is inserted through the plate, and spiral stripes 1c and lc' are formed on the surface in opposite directions. An elastic material 2 such as rubber is attached to the rollers 1 and 1', which have uneven surfaces, by baking or other means, to improve surface friction and provide cushioning properties. There is.

The above roller 1. 1' is equipped with gears 3, 3' of different diameters on its drive shafts 1b, lb', which are meshed with each other. Therefore, in this embodiment, the roller 1 is extended so that its peripheral speed is higher than that of the roller 1'. The gears 3 and 3' are provided with driving force from a motor through a separate transmission system. Further, a hopper 4 is provided above the pair of rollers, and the hopper 4 serves as a trap for introducing, for example, garlic cloves A covered with the skin.

Further, a rubberized chute 5 having a plurality of sorting areas 5a, 5b, 5c in the longitudinal direction of the rollers is disposed below the pair of rollers. , a fan 6 is provided to provide a sorting air across the chute 5. Then, the bottles A that fall into the first sorting area 5a and the second sorting area 5b are transported to the conveyor 7a,
At step 7b, the conveyance is completed, and the article is sent to a place for the next processing (for example, washing, sterilization, etc.). In addition, defective products such as broken paper pens with skins and even large skins fall into the third sorting area 5c. This is disposed of as waste. A long-bodied rotating brush 8゜8' is installed directly below the pair of rollers, and is driven by the aforementioned motor to remove dust such as skin that adheres to the roller surface. working for

In such a configuration, from the hopper 4 to the roller l.

When the cylinder A reaches the surface of 1', its contact point a is first sent in the direction of the arrow x by the spiral thread IC, and the contact point a is moved by the spiral thread 1c/. arrow x
'The force is sent in the direction. Therefore, between the two liquid contact points a and b,
A tensile action acts to tear the skin. However, since the circumferential speed of one roller 1 is faster than that of the other roller 1, the material is sent along the spiral of roller 1, and the skin is peeled off in the meantime.

Then, due to the difference in circumferential speed of the spiral strips tc and 1c/, a positional shift occurs between the facing surfaces approaching each other, and the state changes from the state shown in FIG. 5 to the state shown in FIG. 7, for example, and the roller t
, l' are substantially enlarged, and the peeled material is sequentially fed through the larger gap to the bottom of the roller pair. Thereafter, the dust is sorted by the fan 6 and falls into the sorting areas 5a and 5b of the chute 5 according to the particle size, and the dust is carried out from the chute 4C.

In this way, due to the special shape of the pair of rollers and the difference in circumferential speed, the Rinpen etc. At this point, it is ejected downwardly through the enlarged roller gap, so that complete peeling can be achieved without abrasions.

In addition, in this embodiment, the peeling of garlic was shown and explained, but it can of course also be used for peeling onions, etc. As detailed above, the present invention uses a pair of rollers. Attach an elastic material such as rubber to the surface,
By forming unevenness with cushioning properties on the surface, during this time,
In a device in which a skinned garlic or other garlic is put in and the outer skin is removed while passing through the rollers, the unevenness on the surface of the roller pair has a spiral shape with a small inclination angle as a whole, and the opposing roller The direction of the spiral is reversed, and the circumferential speed of the roller is different. Due to the spiral, the ring, etc., is subjected to a peeling action due to tensile force on the skin, and is prevented from moving in the axial direction. The skin stays on the roller pair for a long time, and when the skin is completely peeled off, it can be released downward through the enlarged gap between the roller pair, making it possible to achieve complete peeling of the epidermis without causing any abrasion. 0
