Description

[Detailed Description of the Invention] The present invention is a hook-shaped super-finishing copper board for woodworking, which is equipped with a blade relief mechanism used for finishing wood in the construction and woodworking industries.

In detail, the circular copper plate can be raised and lowered freely, and when cutting material, it is lowered until it is restricted by the lowering limiter piece and the blade is cut into the material, but when not cutting, it is raised until it is restricted by the upper limiter piece. , relates to a copper plate that protects the knife and the material by preventing the knife from hitting the material and preventing the material from hitting the knife against the material.

Next, an example of the implementation of a hook-shaped super-finished copper board for woodworking equipped with a blade relief mechanism according to the present invention will be described based on the drawings.

In the figure, reference numeral 1 denotes a machine base, with a chiffle 2°3 installed at the front and rear of its upper part, and a support frame 8 horizontally supported by a vertical guide 5 and engaged with an elevation adjustment member 7 installed between the tables 2 and 30. ,
A material conveying belt 4 is stretched around this support frame 8.

A cutter holder 6 is supported by the vertical guide 5 and is movable up and down above the material conveying belt 4. The cutter holder 6 has a feed screw rotated by a reducer motor 18 attached to the upper part of the vertical guide 5. The vertical adjustment member 1T such as the above is engaged.

19 is a nut a that is screwed onto the screw-type elevation adjustment member 17 to support the knife holder 6; and an adjustment nut a that is loosely engaged with the elevation adjustment member 17 and screwed onto the cylindrical portion of the knife holder 60) A spring-type cushion mechanism inserted between C and C uses the elasticity of the spring to hold down the knife holder 6, and when the pushing blade of the material acts on the knife holder 6, the tension of the spring causes the knife to be held. Body 6 is dismissed from work.

Reference numeral 10 denotes a circular concave groove provided in the center of the knife holder 6, into which a circular copper disc 11 is fitted so as to be rotatable and movable up and down, and this circular copper disc 11 supports a knife stock 12 to which a male blade 9 is attached. A descending restriction piece 22 is attached to the lower part of the groove 10 to limit the descent of the circular copper disc 11 to a position where its lower surface coincides with the lower surface of the knife holder 6.
A rise limiting piece 22 is provided on the upper part of the blade holder 6 to limit the rise of the circular copper disc 6 to a position where the male blade 9 supported by the circular copper disc 6 does not touch the material.

Reference numeral 21 denotes a pressing member attached to the blade holder 6 in correspondence with the circular copper disk 11, and the circular copper disk 11 is lowered as described above using a cam shown in FIG. 2 or a mini cylinder shown in FIGS. 3 and 4. It is pressed and fixed to the limiting piece 22.

Reference numeral 20 denotes a relief member for releasing the circular copper plate 11 until it hits the above-mentioned rise limiting piece 22'. When using the pressing member 21 as shown in Figures 2 and 3 of the drawings, a spring is used, as shown in Figure 4 of the drawings. When using a pressing member 21 like this, the pressing member 21 also serves as the pressing member 21.

Reference numeral 15 denotes a motor with a brake that drives the material conveying belt 4, and the material conveying belt 4 is driven in forward and reverse directions by switching its rotation.

13 is a detector such as a microswitch or phototube installed in the material feeding path to detect the trailing edge of the material, and the detection signal is sent to timer 1.
6 to the rotation selector switch 14 of the motor 15 with a brake, and after the material is removed from the area 9, the motor 15 is rotated in the reverse direction.

The pressing member 21 of the circular copper disc 11 described above is operated downward when the material feeding belt 4 rotates in the material feeding direction, and raised when it rotates in the return direction, by the changeover switch 14 or another switch interlocked therewith. This is to make it work.

One embodiment of the hook-shaped super-finishing copper board for woodworking equipped with the blade release mechanism according to the present invention has the above-mentioned configuration. 21 is a circular copper plate 11 as shown in FIGS. 2 to 4 of the drawings.
is lowered and fixed to the lowering limiter piece 22 under pressure.1 Usually,
The lower surface of the circular copper disc 11 is aligned with the lower surface of the knife holder 6,
Since the region 9 of a predetermined size is made to protrude from below the lower surface of the blade holder 6, the upper surface of the material is cut by the region 9. When the upper surface has been cut, the detector 13 detects this and the material conveying belt 4
At the same time, the rotation of the pressing member 21 is reversely operated. Therefore, the circular copper disc 11 is operated by the relief member 20 in the case shown in FIGS. 2 and 3, and by the pressing member that also serves as a relief member in the case shown in FIG. 4. 21, the materials are pushed up and stopped against the rise limiting pieces 22', and the region 9 is retracted from the lower surface of the knife holder 6, so that the material to be returned is returned to the front without touching the region 9. be.

In addition, if this copper plate is adjusted downward by replacing or moving the descending restriction piece 22 of the circular copper plate 11 provided on the blade holder 6, the lower surface of the circular copper plate 11 will hold the blade. Adjust the lower surface of the knife holder 6 so that it protrudes a little more than the body 6, and adjust the lower surface of the knife holder 6 to have a medium-height shape.Also, the cut part of the large square material with a warp is brought into complete contact with the circular copper disc 11. It is possible to ensure reliable cutting of similar materials.

Conventional hook-shaped super-finishing copper discs for woodworking have a blade holder above a material conveying belt that is rotated in forward and reverse directions by a reversible motor.
Since this knife holder was equipped with a region facing one way, the material scraped by the region during transport would stroke the edge of the region back when returning, causing the edge of the region to become a so-called round blade and become noticeably sharper. It wears out and becomes uncuttable in a short period of time, and if the finished surface of the material is rubbed by the area, it has the disadvantage of causing roughness and abrasion. It is impossible to cut this type of material because it is not possible to make the cutting part of a large square material with a warp come into close contact with the circular copper disc by making the cutting part slightly protrude from the blade holder and making the blade holder a medium-high shape. , it had no utility value for construction purposes, which require a lot of processing, such as large square timbers.

However, in the hook-shaped super-finished copper disc for woodworking equipped with a blade release mechanism according to the present invention, a circular groove is provided in the blade holder corresponding to the upper part of the material conveying belt, and the circular copper disc is movable up and down in this groove. The material is fitted and moved up and down by the pressing member and the relief member in conjunction with the feeding back of the material within the range regulated by the descending limiting piece and the ascending limiting piece, and when the material is lowered, the region protrudes from the blade holder. This machine cuts the transferred material, and when it goes up, it retracts the edge to prevent it from touching the returned material, preventing the returning material from stroking the edge back, so there is less wear on the edge, resulting in a round blade. Therefore, good cutting performance is maintained over a long period of time, and the finished surface of the material is not rubbed against local areas, causing roughness or abrasion islands.

In particular, this copper plate is designed such that the circular copper plate is fitted into the circular groove of the blade holder so that it does not move in the material feeding direction, and during cutting, it is pressed against the descending restriction piece by the pressing member, so that it can move in the vertical direction. Since it is immovable, the area is stable and reliable cutting as in the case of a fixed position, and if necessary, the lowering limiter piece can be replaced or the position adjusted, and the stopping position of the knife stock can be adjusted to hold the blade. By setting the blade holder so that it protrudes slightly from the body, the cutting part of a large square piece with a curve can be brought into close contact with the circular copper plate by making the blade holder into a medium-height shape, making it possible to reliably cut materials such as these. Therefore, it is particularly effective for construction applications where large square timbers are often processed.

In addition, the blade release mechanism of this copper disk allows a single piece to emerge from and disappear from the blade holder by simply moving the circular copper disk up and down a minute distance within the groove of the blade holder, allowing for quick and reliable blade release. In addition, the structure is simple, the manufacturing cost is low, and it is convenient that it can be easily implemented on an existing copper plate.
