Abstract

PURPOSE:To contrive to improve the durability of bearings by a method wherein a roller bar, which is formed by fitting roll blocks to one another, is driven at the speed, which is the same as or slightly faster than the peripheral speed of a material wood, and dispersedly supported at the front of a cutting edge rest, which is provided so as to advance to and retreat from an edged tool. CONSTITUTION:A roller bar 11 formed by fitting fitting projected parts, each of which is provided at one end of each roll block 10, and fitting recessed parts, each of which is provided at the other end of each roll block 10, to one another so as to set its axis line parallel to the edge line of an edged tool 5 is arranged at the front part of a cutting edge rest 6. The front lower end part of the cutting edge rest 6 is projected so as to bring a blade 14 into slidingly contact with the lower end peripheral surface position of the respective roll blocks 10, which constitutes the roller bar 11. When the cutting is done by abutting a plane stock 7 against the outer periphery of a material wood 1 after the heart of the material wood 1 is held with spindles 3, the cutting is done in uniform thickness, since the peripheral speed of the roller bar 11 becomes almost equal to the speed of the outer periphery of the material wood 1.

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to the improvement of a roller bar constituting a veneer lace cannon, and in particular, to prevent deflection as a reaction force generated when pressing raw wood, and to improve the uniformity of the roller bar. This invention relates to a veneer lace for obtaining a veneer spout plate with a suitable cutting thickness.

``Prior art'' Normally, when cutting logs, a turret is moved a predetermined distance per revolution of the spindle against the outer circumferential surface of the log that is gripped and rotated by a spindle, and is attached to the turret constituting the turret. A veneer veneer plate of a predetermined thickness is cut between the blade and the cutting edge attached to the cutting edge rest.

Conventionally, the cutting edge has mainly adopted a fixed nose bar that has a ridgeline parallel to the rotation axis at the tip, that is, the side that contacts the raw wood, and in some cases, the cutting edge has a fixed nose bar that has a ridge line parallel to the rotation axis of the cutting edge. A roller bar that follows is adopted.

In the former type of nose bar, the ridgeline, which is the sharp point, presses against the outer circumference of the log just before cutting begins, so the veneer veneer is cut while being pressed once, and then immediately released suddenly, resulting in As a result, the back of the cutting edge of the cutter is always pushed toward the log side through the veneer veneer, indirectly preventing vibrations during cutting and contributing to uniformity of the thickness of the veneer veneer. However, excessive pressure causes wear on the sharp part of the nose bar and the back of the cutting edge line of the cutter, which not only causes separation during maintenance such as polishing, but also causes roughness on the surface of the veneer being cut. It also becomes. In particular, due to the properties of the raw wood, such as hardness and softness, cracks at the end, rot, knots, etc., the shape of the cut grain may change slightly, causing cracks and cracks during cutting.
Chips, knots, and other fragments can become stuck, causing the blade to jam or be pushed out, or leave knife marks on the veneer board after cutting, reducing its quality.

In the latter case, the roller bar touches the outer circumference of the log,
Since the roller bar is driven by the rotation of the log, if the outer circumference of the log in the longitudinal direction is in contact with each other, that is, if the log is perfectly circular, even if the blade jams or the blade is pressed as described above, However, the possibility of debris remaining due to the rotation of the roller bar is reduced, and the rate of quality deterioration of the veneer veneer after cutting is reduced9. In order for the rotation of the log to follow the rotation of the log faithfully to the roller bar, it is necessary to hold the axes of the log and the roller bar parallel to each other. When the roller bars, whose ends are supported by the cutting edge stand, are pressed against each other, bending stress is generated in the roller bars and they tend to bend. Toshinari.

If the diameter is made larger, the deflection due to bending stress can be eliminated to some extent, but the larger the diameter of the roller bar, the greater the distance between the tangent from the axis of the roller bar to the outer circumferential surface of the log. As the roller bar becomes larger, there are many areas where the outer circumferential surface of the roller bar does not come into uniform contact with the outer circumferential surface of the log, making the cutting condition of the veneer veneer unstable and resulting in a decrease in quality. In view of the above, the present invention has been developed in which a roll block divided into a plurality of pieces is mutually attached to the front part of a cutting tool rest that is installed to move forward and backward with respect to a cutter attached to the tool rest. A roller bar configured to fit into the blade and have an axis parallel to the cutting edge line of the cutter is supported at a plurality of locations in the longitudinal direction of the roller bar by bearings fitted in each fitting part, and A blade is installed that slides on the circumferential surface of each roll block that makes up the roller bar, and the roller bar is driven at the same speed or slightly faster than the cutting speed of the raw wood to stably maintain the cutting state of the plywood board. be.

At the start of this cutting, the circumferential speed of the roller bar 11 is
6, the peripheral speed of the log 1 is the same as, or slightly faster than, the circumferential speed of the log 1. Regarding this control of the motor 16, the circumferential speed of the log 1 is changed from the log 1 gripping position to the position of the turret 7, that is, The radius of the log 1 is calculated by the radius of the log 1 to the point where the roller bar 11 located at the tip of the cannon 7 is in contact with the outer circumference of the log 1, and when the cutting of the log 1 is completed, the calculated circumference of the log 1 is The motor 16 is always driven at a peripheral speed that is the same as the peripheral speed or slightly faster than the peripheral speed. In this case, each time the diameter of the log decreases as cutting progresses, the rotation of the spindle 3 will be increased.
If the rotation of is constant, the circumferential speed will gradually increase as the diameter of the log decreases, but since the position of the turret 7 is constantly detected, changes in the circumferential speed can be grasped at all times.
This is output to the motor 16 to drive the roller bar 11 at a circumferential speed that is the same as, or slightly faster than, the circumferential speed of the log l.

When the turret 7 is moved forward after the above initial settings are completed, the roller bar 11 located at the front of the turret holder 6 comes into contact with the outer circumferential surface of the log 1, and the blade 5 attached to the turret holder 4 is moved forward. The veneer veneer is cut to a thickness based on the amount of step feed.

At this time, the roller bar 11 is being rotated at a circumferential speed that is the same as or slightly faster than the circumferential speed of the log 1, but when it comes into contact with the outer circumferential surface of the log 1, the circumferential speed is almost assimilated to the circumferential speed of the log 1. If the log 1 is still in an irregular shape, the cutting waste from the initial cutting, the hardness and softness of the log 1, cracks at the end, rot,
When cutting knots, etc., even if cracks, chips, knots, and other debris occur during cutting, the forced rotation of the roller bar 11 prevents them from remaining between the raw wood 1 and the roller bar 11, allowing the veneer to stand alone. It will be immediately discharged downward along with the board.

Furthermore, even if the cutting chips, fragments, etc. occur in localized areas along the length of the log 1, since the roller bar 11 is supported at multiple locations along its length, it will not be affected by the local load. A uniform state of contact can be maintained without the axis being bent.
