Abstract

(57) [Problem] To continuously cut the inner and outer surfaces of a bamboo having a length of at least 20 cm and having at least a circumference divided into two in a length direction regardless of presence or absence of inner and outer nodes. SOLUTION: The height and width of the divided surface are cut with fixed blades 32, 42 and rotary blades 33, 43 with reference to the bottom of the bamboo, and the inner surface including the inner section is roughly roughened with a cutting tool 54 having a sectional shape similar to that of the bamboo. After the cutting, a constant inner diameter is finished by a cutting tool 64 planted at the circumferential tip of the disk, and then a constant outer diameter by a cutting tool 74 planted at the inner circumferential tip of the annular disk including the outer periphery including the nodes. In order to prevent the bamboo from moving in any direction other than the traveling direction between each process, the bamboo is processed by an apparatus having a support portion combined with a V-shaped roller 20.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface cutting apparatus for continuously removing inner and outer skins and nodes from a material obtained by cutting a round bamboo into an appropriate length and dividing a cross section circumference in a length direction.

[0002]

2. Description of the Related Art The material shapes in the step of removing nodes and skin on the inner and outer surfaces are classified as follows. 1) When sorting by length, there are two types of processing: short processing using only the internodes and long processing using nodes. 2) If it is sorted by the division shape of the cross-section circumference, it can be divided into four or more, three, two and one (one cut in the circumference)
There are four types.

[0003] An application relating to the processing of the inner and outer surfaces of bamboo has been seen for a long time. Japanese Patent Application Laid-Open No. 48-87331 discloses a method of dividing a bamboo into a fan-shaped section in the longitudinal direction and cutting a square section material from the divided material by cutting. In Japanese Patent Application Laid-Open No. 59-48103, the circumference of the tip of a round bamboo is equally divided, and the inner peripheral wall is cut with a cylindrical tool having a tangential cutting edge. A technique of dividing an inner wall surface in a length direction with a tool protruding radially is disclosed.

[0004] Further, the applicant's prior application includes Japanese Unexamined Patent Publication No.
Japanese Patent Application Laid-Open No. Hei 8
Japanese Patent No. 318508 discloses a processing technique using a small internal cutting blade while rotating bamboo by an apparatus equipped with a mechanism for correcting and rotating a warp, and Japanese Patent Application Laid-Open No. 8-318509 discloses a mechanism for correcting and rotating a bamboo. Disclosed are techniques for processing the outer surface with an endless cutting band while rotating and moving the bamboo with an apparatus.

[0005] Bamboo subjected to such processing is cut in a habitat, after which the leaves and leaves are removed and cut into lengths suitable for transportation.
After preventing the risk of dry cracking by taking measures such as submersion, start by making the length and cross section suitable for processing, and then heating hot water or caustic soda to avoid seepage of the internal contents after processing. It is common to immerse in a liquid and perform a treatment such as degreasing.

[0006]

As a problem in processing the inner and outer surfaces, Japanese Patent Application Laid-Open No. 48-88831 discloses a method of shaving a plate from bamboo having a fan-shaped cross section, so that the processing amount is large, the yield is low, and the product itself is small. In JP-A-59-48103, the rotary blade used for inner surface cutting is a one-way cutting tool with a fixed outer periphery, and therefore, in the case of bamboo whose cross-sectional area gradually decreases in the length direction, the workable length is limited. Moreover, it is difficult to imagine that it is suitable for removing a node part deformed on the inner surface.

[0007] The applicant's earlier application enables long processing by a method of dividing a round bamboo into one piece. This has the advantage of obtaining a plate material having the maximum width that can be obtained from the round bamboo, but at the same time, the equipment cost is low. It is difficult to use a profitable base when using short length machining because it is expensive, and it is essential that either the round bamboo or the rotary blade reciprocate more than the inner diameter machining length, and unidirectional continuity of machining In addition, the rotating blade support portion is long and the run-out occurs due to the problem of rigidity, and the total length of the inner surface processing machine needs to be at least twice as long as the material.

[0008]

SUMMARY OF THE INVENTION The present invention solves a problem in processing the inner and outer surfaces of round bamboo, and maintains the initial installation posture regardless of the length of the material and continuously flows backward in one direction. The purpose is to provide a continuous inner and outer surface cutting device.

According to the present invention, a bamboo material having a length of at least 20 cm and having at least a bisection in a longitudinal direction at least with a cross section circumference irrespective of the presence or absence of inner and outer segments is described as A) to F). A) A cutting part that cuts the divided surface of the material to adjust the height, B) A cutting part that cuts the side surface of the material to adjust the width, C) The material is cut by a cutting roll in which cutting tools whose outer edges are arc-shaped are arranged radially. And R) a rough cutting surface provided with at least one outward blade on the outer periphery and having a mechanism for adjusting a contact position between the inner surface of the material and the outward blade. E) finishing cutting part of the inner surface, E) a cutting tool having at least one inward blade on the outer periphery, a contact position adjusting mechanism (76) for the outer surface of the material and the blade, and a cutting tool having a passage through which the material can pass; Outer surface cutting part to smooth the outer surface, F) Each cutting Of a Takenouchi outer surface continuous cutting apparatus characterized by processing the inner and outer passed through any combination of the support portion, the responsible for material support and feed before and after.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is to divide a bamboo bamboo of an appropriate length into two or more parts, maintain the initial posture, and make the flow of the material accompanying the cutting one direction, and connect the inner and outer surfaces including the joint part continuously. This is a continuous inner and outer surface cutting device that cuts to a required thickness.

In the step of processing the inner and outer surfaces, a material obtained by dividing the cross section circumference in the longitudinal direction by a length selected from the range of 20 to 500 cm, preferably 20 to 250 cm, more preferably 20 to 120 cm, It is mounted on a moving part such as a conveyor with the dividing surface facing up, and a roller for suppressing the dividing surface with an elevating function is arranged above the moving part, and the pinching angle is automatically adjusted according to the arc part of the outer surface of the material below. A V-shaped roller and a fixed roller to be adjusted are arranged, and a support portion is provided for forcibly restricting the warpage of the material by a plurality of combinations thereof and preventing the swinging of the dividing surface in progress. It is desirable that one of the upper and lower rollers of the supporting portion has a drive mechanism.

At the entrance to the first supporting portion, a portion protruding from the inner section of the material dividing surface and a plurality of fixed blades and rotating blades for the purpose of keeping the height and width uniform are provided as a set, or between the blades. The fixed blade may be formed in a scraper shape, and the rotating blade may have a number of blades spirally arranged on the rotor surface. It is desirable that each blade has a position adjusting mechanism in the height and width directions.

At the end of the moving part, there is provided a cutting roller having a cutting tool radially arranged in the rotation direction and a receiving roller on the outer surface of the material, the cutting tool having any number in the range of 3 to 6 and having a tip close to the inner surface of the material. Is rough-cut on the inner surface including the node by the rough-cutting section where the is disposed. Although an appropriate number of support parts are arranged between each part,
One of the rollers forming the upper roller is replaced with a tire-shaped drive roller having a circular arc cross section, and the lower side supporting the outer surface of the material is also made a small-diameter drive roller, and has a structure that combines feeding, rocking prevention and warpage measures. The drive may be either an individual method such as a motor or a connection method using a chain or a belt.

The material after the rough cutting is sent to the inner finishing cutting section in the same posture, but the cutting section attaches a disk to the tip of the rotating shaft supported by the bearing, and attaches the outer circumference to each of the outer circumferences of the disk. A cutting tool having blades in two directions of rotation and rotation is selected from a range of 3 to 6 pieces, uniformly arranged and rotated, and the inner surface of the material is continuously cut through the cutting edge on the same disk to finish.

The material whose inner surface is finished is fed into a cutting part on the outer surface through a plurality of sets of upper and lower rollers, and the cutting part is attached with a disk having a central hole on a hollow rotary shaft supported by a large-diameter bearing. A cutting tool provided with two blades on the inner periphery of the disc in the two directions of outer periphery and rotation is selected from a range of 3 to 8 pieces, uniformly arranged and rotated, and the outer surface of the material is made to have the cutting edge of the center hole of the disc. Continuous cutting and finishing along the line.

In any of the inner and outer cutting portions, it is necessary to move the tip of the cutting tool to a machining position on the inner and outer surfaces of the material, and the inner surface of the cutting tool disk needs to be replaced according to the inner diameter of the material. Is 4 times the adjustment allowance for the cutting tool tip protruding from the disk.
Align replacement discs with a diameter of 10 mm. The cutting tool disk on the outer surface has a sufficient hole diameter and does not need to be replaced, and an adjusting mechanism is mounted on the cutting tool holding portion facing the inner periphery to match the outer diameter of the material.

It should be noted at the time of machining that the inner and outer surfaces of the material that touch the cutting tool do not move in directions other than the traveling direction. This movement occurs due to the feed roller pitch for short objects and warpage for long objects. The structure and number of the supporting parts disposed before and after the cutting part are particularly important, because the smoothness of the machined surface is impaired and the life of the cutting tool is impaired by the hard fibers on the material surface. The structure of the support part provided good cutting effects regardless of the length.

[0018]

The inner / outer surface continuous cutting device according to the present invention moves a material, which is short to long, divides a cross-section circumference in the length direction and includes some warpage, in one direction while maintaining an arc shape. Remove the inner and outer nodes and epidermis, and adjust the width and thickness.
