Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an improvement of a device for peeling the cuticles of bamboo shoots.

Prior Art and its Problems The applicant has proposed a new machine for peeling and removing the cuticles of bamboo shoots, the skins of small potatoes and potatoes, and the epidermis of burdock, etc. in Japanese Patent Application Laid-Open No. 57-206372.

As shown in FIGS. 3 and 4, the machine according to the above application has a front face 4 made of an elastic material on a frame 1 inclined laterally, and a large number of grooves 3 in the lateral direction. The rectangular plate 2 is tilted longitudinally and longitudinally and fixed with pins 8, 8 to form the receiving surface body 5, which is reciprocated on the inclined surface of the frame 1 by a driving means (not shown). (see arrow a), while a plurality of spiral blades 7 made of an elastic material are made to extend along the longitudinal direction of the roll 6 and protrude in the opposite direction to the rotation direction of the roll 6 above the lower part of the receiving surface body 5. The rollers 6 are arranged in a substantially V-shape as shown in FIG. 4, with the rollers 6 being pivoted in parallel with the receiving surface 5, and the rollers 6 are rotated on their own axis from below to above the receiving surface 5 (see arrow b).

When the workpiece 10 is guided into the V-shaped valley formed by the receiving surface 5 and the roll 6, the workpiece 10 is subjected to the reciprocating motion of the receiving surface 5, the rotational movement of the blades 7, and the swinging motion of the strip-shaped plate 2. The movement acts synergistically, and the workpiece 10 gradually rotates forward while sliding on the receiving surface 5, and the skin is peeled off.

In this case, water falls in a shower toward the V-shaped valley, serving as a suitable lubricant and also removing deposits.

However, when the workpiece is a bamboo shoot, its shape is basically a cannonball shape, but it has various shapes, such as being slightly curved and only the body becoming extremely thick. Although the cuticle was successfully removed by circumferential rotation, the tip, which is important for grading bamboo shoots, was sometimes broken or worn.

The cause is largely related to the way the bamboo shoots are rotated. In other words, the cuticle of a bamboo shoot is peeled off as the narrow part of the tip turns downward;
It does not rotate about the line connecting the tip and the center of the base, but rotates while being rotated on the V-shaped valley. Depending on the shape of the bamboo shoot, the circular locus drawn by the tip may become large, and during this time the tip may be strongly caught on the unevenness of the rectangular plate of the receiving surface, causing the tip of the bamboo shoot to break or break. This means that only those parts are printed intensively.

Problems to be Solved by the Invention This invention consists of a rectangular plate whose surface is made of an elastic material and which is provided with a large number of grooves in the transverse direction, on a laterally inclined frame. In addition, the receiving surface body is constructed by attaching it tilted back and forth, and a roll having a plurality of spiral blades made of an elastic material protruding in the longitudinal direction is supported above the lower part of the receiving surface body in parallel with the frame. In the bamboo shoot cuticle peeling machine, the cuticle of the bamboo shoot is moved reciprocally along an inclined surface and the roll is rotated so that the blades move upward from the bottom of the receiving surface. The goal is to prevent this from occurring.

Technical means The technical means to solve this technical problem are:
The depth of the grooves in the strip-shaped plate is made gradually shallower toward the bottom.

Effect of technical means According to this technical means, the cuticle of the bamboo shoots guided between the receiving surface and the roll is peeled off by the action of the spiral blades accompanying the reciprocating motion of the receiving surface and the rotation of the roll. As the bamboo shoot moves forward, the tip of the bamboo shoot facing downward comes into contact with the lower part of the strip-shaped plate that makes up the receiving surface, but there is almost no depth in the groove at the bottom of the strip-shaped plate, and the tip of the bamboo shoot This will cause the parts to slip.

Effects of the invention Therefore, as a result of the tip of the bamboo shoot slipping, the tip of the bamboo shoot does not come into strong contact with the strip-shaped plate, and during its rotation, it gets caught in the groove and breaks, or the tip gets worn out. Since the fibers are not exposed, the product will not be degraded in quality during quality evaluation in pre-processes such as canning.

Embodiment FIG. 1 is a longitudinal cross-sectional view of a strip-shaped plate 12, in which the depth of the groove 13 below the substantially central portion becomes shallower toward the lower end.

In FIG. 2, the depth of the groove 13 is gradually reduced from the upper end to the lower end.
