Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to an apparatus for peeling the skin of workpieces such as radish, radish, and carrots at high speed using a peeling roller having a large number of abrasives attached to the outer surface.

[Prior art]

Traditionally, when peeling workpieces such as turmeric and radish, the workpiece was first washed with water to remove the dirt and mud, and then the skin was removed exclusively by hand using a knife or peeling tool. However, if the amount is small, it may be fine, but if it becomes large, not only the area around the washer but also the worker will be exposed to mud spray during washing, worsening the working environment, and hands and fingers will be damaged due to manual peeling. Of course, a corresponding amount of fatigue accumulated in the wrists, joints, shoulders, etc., and along with this fatigue and increased numbness in the fingers and arms, deep or scratchy skin peeling occurred, resulting in lower efficiency and lower yields. . On the other hand, some machines have been proposed that use a pair of rollers to peel long and thin workpieces such as radish and radish; It consists of a pair of rollers covered with brushes, and as the peeling process progresses, dirt and mud can enter and accumulate inside the brushes, reducing the peeling effect, so a washing process is required beforehand to remove the mud. Not only was the peeling not only impossible, but also the peeled shavings accumulated inside the brush, significantly impairing the peeling effect. In order to overcome the drawbacks of such conventional peeling machines, the inventor of the present invention previously proposed in Japanese Utility Model Publication No. 58-14877 a pair of plate-shaped elastic piece members to which an abrasive material is attached, based on the peeling action by polishing. A plurality of pieces are attached to a drum-shaped roller at appropriate intervals, and the skin of burdock etc. is efficiently and reliably peeled by using the elasticity of the elastic piece member and the abrasive action of the abrasive material. I suggested a peeler. However, the peeling machine according to the above proposal,
Since the elastic strip member with the abrasive material attached is pressed against the surface of the workpiece by the rotation of the drum-shaped roller and polished, the processing time is greatly shortened compared to conventional peeling machines. While uniform peeling work can be performed over the entire surface of the workpiece, the elastic strip members slide freely in the radial direction of the roller, and since each elastic strip member is discontinuous with respect to each other, the roller can be moved at high speed. When the elastic piece is rotated, the abrasive material attached to the tip of the elastic piece repeatedly hits the surface of the workpiece, a so-called lapping phenomenon, which may cause damage to the workpiece, which has a relatively weak skin, such as a radish. In this case, striped patterns or unevenness may occur on the surface of the product, and there remains room for further improvement in this respect.

[Purpose of invention]

The present invention focuses on the problems with such conventional peeling devices, and the peeling roller is composed of a drum-shaped roller body whose outer periphery is surrounded by an endless elastic member with a large number of abrasives attached to the outer surface. An elastic foam is filled between the back surface of the elastic member and the roller body to urge the abrasive material radially outward of the roller body, and the elastic member and the roller body are connected via a connecting member. By reliably transmitting the rotational torque applied to the roller body to the elastic member, the surface of the workpiece is continuously polished with the abrasive material to improve the finished state of the workpiece, thereby solving the above problem. This is an attempt to resolve the point.

[Structure of the idea]

To achieve the above object, the present invention has a structure in which a pair of peeling rollers are arranged with their axes parallel to each other and rotated in opposite directions, and a workpiece such as radish or radish is inserted between both peeling rollers. In the peeling device for polishing the skin of the workpiece, each of the pair of peeling rollers has an hourglass-shaped roller body as a core having a recessed portion facing the other roller in the center, and the outer periphery of the roller body is A large number of abrasives are surrounded by an elastic member attached to the outer surface, and the elastic member is connected to the bottom surface of the concave portion of the drum-shaped roller body via a connecting member, and an elastic member is provided between the concave portion of the roller body and the elastic member. The main feature is that the structure is filled with foam.

[Effect of the idea]

As described above, in the peeling device of the present invention, the peeling roller has a drum-shaped roller body as its core, and its outer periphery is surrounded by an elastic member having a large number of abrasives attached to the outer surface, and the elastic member is attached to the drum-shaped roller. Since it is connected to the bottom surface of the recess of the roller body via a connecting member, and an elastic foam is filled between the recess of the roller body and the elastic member, conventional peeling means or peeling methods are required. Compared to the machine, the following (a) to
It exerts various effects as described in (f). (a) Conventionally, it was necessary to first remove the dirt by washing with water, etc., but in the present invention, since an abrasive action is added, peeling can be performed without the need for a washing process. Therefore, the skin is not exposed to mud spray during peeling, and the processing time is also shortened. (b) Since the abrasive material is pressed onto the surface of the workpiece by using the elasticity of the elastic member and the elastic foam, it can be applied to the outer shape of the workpiece, and therefore it can be applied to each workpiece. Even if there are thick and thin parts,
Even if the workpiece is thick and thin, it can absorb dimensional differences to some extent and can be peeled under uniform pressure on average. (c) The rotational torque applied to the roller body by the connecting member is reliably transmitted to the endless elastic member to drive it, and the surface of the workpiece is polished with the abrasive material attached to the entire circumference of the elastic member surface. Because it is continuously polished, there is no slippage between the elastic member and the roller body even when rotating at high speed, and there is no need to worry about roughening the surface of the workpiece, allowing for an improved finish. . (d) Since peeling is done by polishing with an abrasive material, the peeling waste becomes fine pieces and takes up a small volume, making it very easy to dispose of. (e) Since polishing with an abrasive material is surface polishing, there is no unnecessary peeling, and the yield after peeling is improved. (f) The combination of the above-mentioned effects not only improves work efficiency and greatly reduces worker fatigue, but also significantly improves peeling efficiency.
