Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a peeling roller for peeling the epidermis of elongated workpieces such as root vegetables such as burdock root, radish and carrot at high speed and smoothly. . In particular, a pair of peeling rollers are arranged in parallel with each other with their axes parallel to each other, and are rotated in opposite directions, and a work piece is inserted between both peeling rollers to polish the skin thereof. It concerns a stripping roller.

[Conventional technology]

Conventionally, when peeling various slender items such as burdock root, it is common to use a kitchen knife or a simple peeling tool after first removing the mud. In addition to accumulating fatigue in various parts of the body and, in turn, adversely affecting health, the work piece becomes deeply peeled or has a tendency to be scratched, resulting in a decrease in efficiency and a decrease in yield.

Various kinds of peeling machines, such as a machine consisting of a pair of rollers having a brush coated on the surface thereof, are known to remove the drawbacks of such manual peeling. This is a problem for practical use because it is infiltrated and accumulated, and peeling debris accumulates, and because the brush is worn, damaged, or distorted, the peeling work is practically impossible or the peeling efficiency is significantly reduced. It was

In order to overcome the drawbacks of the existing peeling machine, the present inventor has already formed a plurality of plate-like elastic member pieces to which a granular abrasive has been adhered on the outer periphery of a pair of hourglass-shaped roller cores based on the peeling action by polishing. By forming a cylindrical roller body that surrounds at appropriate intervals and filling elastic foam as a cushioning material between the recess of the drum-shaped roller core and the elastic member, centrifugal force at high speed rotation is formed. We have already proposed a peeling device that utilizes the elasticity of the elastic member pieces and the polishing action of the abrasive.

[Problems to be solved by the device]

This kind of peeling device presses the elastic member piece to which the abrasive is adhered to the surface of the work piece by the rotation of the hourglass roller and polishes it. It has the advantage of being significantly shortened and capable of performing uniform peeling work over the entire surface of the workpiece.

However, when the peeling roller is rotated at a high speed, the adverse effect caused by the water gradually containing the foam is often greater than the effect as the cushioning material. That is, due to the water content of the foam, a phenomenon occurs in which the central part of the roller swells and exhibits a barrel-like shape.As a result, in extreme cases, the outer peripheral parts of both rollers come into contact with each other due to centrifugal force, and the abrasive grains scatter, finally. Came to break the roller. Further, even in the case of not so bad, there was room for improvement such that the surface of the workpiece could not be uniformly subjected to the polishing treatment, and the treatment area was reduced, resulting in a decrease in stripping efficiency.

In view of the above problems, the present invention has conducted various studies to eliminate the phenomenon of bulging into a barrel-shaped barrel during rotation. As a result, a hollow body is formed between the cylindrical body and the recess of the elastic member. The inventors of the present invention have unexpectedly found that the above problems can be solved, and have reached the present invention. Therefore, an object of the present invention is to provide a peeling roller capable of performing smooth peeling at high speed without causing a barrel-shaped expansion phenomenon. In addition, it is possible to provide a peeling roller that allows the roller to be flexibly attached to the outer shape of the vegetable to be processed and keeps the outer shape of the vegetable as natural after peeling. To aim.

[Means for Solving the Problems]

To achieve the above object, the structure of the present invention comprises a drum-shaped core roller having a recess at the center and a cylindrical elastic member having a large number of abrasives adhered to the outer cover, and the recess and the elastic member. The space between them is formed as a complete hollow portion without being filled with any other material such as an elastic foam, and a plurality of drainage openings are formed in both bent peripheral portions on both sides of the tubular elastic member. It's on a peeling roller.

In a preferred aspect of the present invention, the tubular elastic member is composed of a plurality of elastic plates having a base portion and a connecting portion, and is connected to the bottom surface of the concave portion of the core roller via the connecting portion and the base portion. Are joined together to form a tubular body.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The first embodiment is illustrated in FIGS.
That is, FIG. 1 is a front view showing an outline of a peeling device using a pair of peeling rollers of the present invention, FIG. 2 is a vertical sectional side view of the same, and FIG. 3 is used for the peeling roller of the same. FIG. 4 is a plan view of an elastic plate.

In each of the above figures, (1) and (1) are hourglass-shaped core rollers which form a base of the peeling roller of the present invention and whose central portion is formed in a concave portion (7). The core roller pair (1), (1)
The shafts (2), (2) are arranged in parallel at a predetermined distance from each other, and are supported by a driving source (not shown) so as to rotate opposite to each other. Both rotary shafts (2), (2) are adjustably supported so that the distance between the shafts fits the thickness of one workpiece (A) such as burdock and radish.

The maximum outer diameter of the core roller (1) varies depending on the thickness of the workpiece, but is usually in the range of 60 to 30 mm.

(3) is a cylindrical elastic member that is attached to cover the entire outer peripheral surface of the core roller (1) and the peripheral portions of the side surfaces. The elastic member (3) has an elastic plate (4) having a rectangular base portion (6a) and a triangular connecting portion (6b) as shown in FIG. 3 in which the outer peripheral surface of the core roller (1) is divided into a plurality. The base portion (6a) is joined to each other by a means such as bonding to form a tubular body, and the concave portion (7) of the core roller (1) is inserted through the tip of the connecting portion (6b). The bottom part (7a) in () is detachably fastened with a fixing tool (8) such as a screw.

When the triangular connecting portion (6b) of the elastic plate (4) is formed into the tubular elastic member (3), each elastic plate (4) is positioned adjacent to another elastic plate (4). A window hole (5) is formed in the center in the vicinity.

The elastic plate (4) is formed by punching out a thin plate made of a material such as natural or synthetic rubber having excellent elasticity, water resistance, and corrosion resistance, and a plurality of (four in the illustrated example) the elastic plate. A large number of small pieces of the abrasive material (9) such as small circles are attached to the surface portion of the base portion (6a) exposed to the outer circumference of the roller when the member (3) is joined to the tubular body.

The space between the cylindrical elastic member (3) thus constructed and the recess (7) of the core roller (1) forms a hollow body (10), which is completely filled with elastic foam or the like. However, it is a completely hollow portion, which is an essential requirement of the present invention.

The abrasive material (9) is obtained by punching out a normal sandpaper or other abrasive paper cloth into a small circular shape and aligning and adhering the same with the surface of the elastic plate (4). The shape of is not limited to a circle, but may be various shapes such as a square, an ellipse, and a triangle. Further, it is effective to disperse the core rollers (1) so as to disperse them uniformly over the entire circumference of the core roller (1) in order to improve the finished surface of the workpiece.

4 and 5 show another preferred embodiment of the peeling roller of the present invention. FIG. 4 is a front view of the peeling roller, and FIG. 5 is a side sectional view of the same.

In this embodiment, the tubular elastic member (3) is an integral tubular molded article, for example a rubber tube, the material of which is preferably substantially composed of natural rubber having both flexibility and elasticity. .

When flexible natural rubber is used as the integral tubular molded body (3), when peeling root vegetables such as radish with the roll, in addition to elasticity, flexibility and flexibility of a size suitable for those materials are used. It is preferable because it can easily conform to the outer shape. As a result, the peeling speed is increased, and peeling is possible without losing the outer shape while keeping the natural shape. This leads to an improvement in yield, and finally a peeled product having a natural contour is obtained.

The thickness of the integral tubular molded body (3) varies depending on the thickness of the workpiece, but is preferably in the range of 2 to 3 mm. If it is thicker than this, the flexibility becomes too small, and it becomes difficult to attach the work piece sufficiently, which is not desirable.

A plurality of drainage openings (11) are provided on both bent peripheral edges of the integral small tubular body (3) and serve to drain water that enters the hollow portion (10).

When this integral tubular elastic member (3) is applied to the core roller (1), a tubular rubber (3) slightly longer than the axial length of the core roller (1) is used, and both edges thereof are used. Part of core roller (1)
Enclose the cylindrical portion of the core roller so that it protrudes from each other, and make a radial notch in both protruding portions and bend them toward the circular portions at both ends, and fix or join the peripheral bent portion to that portion, It can be made to be attached. In that case, a plurality of drainage openings (11) are perforated in the bent peripheral edge portion.

The drainage opening at the bent peripheral edge is not limited to the tubular rubber, and the same applies to the tubular elastic member described above.

A pair of the peeling rollers are used as in the above embodiment,
By arranging the rotary shafts (2) in parallel with each other and rotating them in opposite directions, and inserting the workpiece between both rollers, the peeling process can be performed.

Next, the operation of the peeling device using the peeling roller of the present invention will be described with reference to FIG.

First, when a pair of upper and lower hourglass core rollers (1) and (1) are rotated in opposite directions with their concave portions (7) and (7) facing each other, the pair of upper and lower core rollers (1) and (1) are rotated. ) The tubular elastic member (3) attached to the outer circumference is pulled by the action of the connecting portion (6b) in the same rotation direction and integrally rotated, and tends to swell in the radial direction due to centrifugal force. The cylindrical elastic members (3) and (3) of the core rollers (1) and (1) are urged in directions toward each other.

In this state, when the one end of the work (A) to be peeled between the two core rollers (1) is gripped by hand and the tip side is inserted, the elastic member (3) is hollow. While bending in the direction of (10), it curves along the outer shape of the workpiece (A),
According to the curve, the work is brought into contact with the outer circumference of the work piece with an appropriate pressure contact force, and the abrasive material (9) removes dirt and the like adhering to the outer surface and at the same time removes the skin.

At this time, since the abrasive material (9) is continuously abraded along the longitudinal direction of the work piece, the peeled-off skin is separated into fine pieces or pulp when the work piece is moved in and out several times. It

Thus, when the peeling work on one tip side is completed, the processed tip side is gripped and the other untreated side is similarly worked to complete the whole peeling work.

In this way, the work (A) is efficiently peeled from the thick portion at the base to the thin portion at the tip.

In the processing of the work such as mud adhered, a pair of core rollers (1), (1) as shown by the chain line in FIG. 2 to remove the mud and debris. If water is injected from the top and bottom toward the inlet through the water injection nozzles (12) and (12), work can be performed easily without polluting the work environment.

[Effect of device]

The peeling roller of the present invention exhibits the following excellent effects as compared with the known similar peeling roller.

(1) Since both elasticity and flexibility are obtained by the combination of the tubular elastic member and the hollow body air spring, the surface of the peeling roller is flexibly pressed against the surface of the work piece, and its outer shape is obtained. You can fit it exactly. Therefore, even if each work piece has a non-uniform thickness, and regardless of the thickness of the material, it is possible to reliably absorb the dimensional difference and peel on average evenly under peeling. It is possible.

(2) Since it is configured as a hollow body having a completely hollow portion, and the drainage opening portion is provided in the both-side bent peripheral edge portion of the tubular elastic member,
Water that enters the hollow part is drained at any time during high-speed rotation and does not accumulate in the hollow part, so the central part of the peeling roller does not expand like a barrel and is retained in a cylindrical shape. Therefore, smooth and efficient peeling is achieved.

(3) Since the surface of the work piece can be conformed to the outer shape of the work piece, the surface can be surely polished by the abrasive material, so that no unnecessary peeling occurs and the yield after peeling improves. In addition, there is an advantage that after the work, it is finished like a natural shape.

(4) Not only the workability can be improved by the combination of the above-mentioned effects and the fatigue of the worker can be significantly reduced, but also the peeling efficiency can be significantly improved.

(5) Since the space between the elastic member and the recess is formed as a hollow body, the manufacture of the peeling roller can be simplified and the cost can be reduced.
