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, simply forming unevenness and randomly rolling a rimpen or the like on a pair of rollers does not apply tension or compression to the epidermis, making it difficult to elongate it properly.

Furthermore, if the frictional force is increased, the linpen, which has already had its skin removed, will be scratched when passing between the rollers, which may cause rotting in the future.

Since then, various improvements have been made to the shape of the roller surface, but there is still no peeling device that can completely peel the bag without damaging the surface of the bag.
Not realized.

The present invention has been made based on the above circumstances, and a tensile force acts on the surface of the linpen etc. in the axial direction of the pair of rollers, and the linpen is guided between the rollers while giving a peeling effect on the skin. However, it is an object of the present invention to provide a roller-type peeling device in which the gap between the rollers increases during the guidance process, and the peeling device can pass between the rollers without causing scratches on the surface.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. In the drawings, reference numerals 1 and 1' are rollers, and drive shafts 1b and 1 are disposed at the center of the roller cores 1a and la', respectively.
b' is inserted through the plate, and spiral stripes 1C51C' in opposite directions are formed on the surface.

An elastic body 2 such as rubber is attached to the rollers 1 and 1', which have irregularities on their circumferential surfaces, by baking or other means, to improve surface friction and provide cushioning properties. ing.

The rollers 1, 1' are provided with gears 3, 3' having different diameters on their drive shafts 1b, 1b', and these gears are meshed with each other.

Therefore, in this embodiment, the peripheral speed of roller 1 is higher than that of roller 1'.

A driving force from a motor is applied to one of the gears 3, 3' by another transmission system.

Further, a hopper 4 is provided above the pair of rollers, and into the hopper 4, for example, garlic paste A whose skin has been burst is introduced.

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 selective air across the chute 5.

The paper pens A that fall into the first sorting area 5a and the second sorting area 5b are conveyed by conveyors 7a and 7b and sent to a place for the next processing (for example, washing, sterilization, etc.).

In addition, defective products such as broken paper pens with skins, as well as large skins, fall into the third sorting area 5C.

This is treated as waste.

Directly below the pair of rollers, a long-bodied rotating brush 8.8' is installed, driven by the aforementioned motor, and serves to remove dust such as skin adhering to the roller surface.

In such a configuration, the paper pen etc. A that reaches the surface of the roller 1° 1' from the hopper 4 is first sent by the spiral strip 1C at its contact point a in the direction of the arrow The contact point is moved in the direction of the arrow x' force.

Therefore, a tensile action acts between the solid contact points a and l), which acts to tear the skin.

However, since the circumferential speed of one roller 1 is faster than that of the other, the material is sent along the spiral of the roller 1, and the skin is peeled off during that time.

Then, due to the difference in circumferential speed of the spiral strips 1C 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 1
, 1' gap is substantially enlarged, and from the peeled one,
The rollers are sent out one after another through large gaps 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 5C.

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 any abrasions.

In addition, although this embodiment has been described with reference to peeling of garlic, it can of course also be used to peel onions, etc.

As described in detail above, the present invention involves attaching an elastic material such as rubber to the surface of a pair of rollers, forming unevenness with cushioning properties on the surface, and applying phosphorus such as garlic covered with skin between the rollers. In a device in which a pen is inserted and the skin is removed while passing through the rollers, the unevenness on the surface of the pair of rollers has a spiral shape with a small inclination angle as a whole, and the direction of the spiral of the opposing rollers is opposite. Since the circumferential speed of the rollers is different, due to the above-mentioned spiral, the linpen etc. are peeled off by the tensile force on the skin and remain on the pair of rollers during movement in the axial direction. The skin can be discharged downwardly from the enlarged gap between the pair of rollers in a sufficiently peeled state, thereby achieving the excellent effect of achieving complete peeling of the skin without causing any abrasion.
