Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a woodworking machine suitable for processing stile materials and muntin materials for shoji screens.

[Conventional technology]

The processing method for the frame materials and kumiko materials that form the shoji is as follows:
After assigning the square hole machining positions to the frame material on the four sides using a scale, use a ruler to mark each of these assigned positions.

Next, engrave using only the inside of the lined area,
Provide a square hole.

The muntin materials are divided into those for vertical rows and those for horizontal rows, and the muntin materials for vertical rows have the same pitch as the square holes of the vertical frame materials, and the muntin materials for horizontal rows have the square holes of the horizontal stile materials. After assigning the same pitch as the hole and marking it, cut a U-shaped notch.

[Problem that the invention attempts to solve]

Since the machining positions of the square holes on the frame materials and the machining positions of the U-shaped notches for fitting on the muntin materials are manually assigned and marked, it takes a considerable amount of time and causes an increase in costs. There was a problem.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention includes a table that is provided to move at each pitch set in the horizontal direction, a marking device that is placed directly above the table, and a marking device that is placed directly above the table. It consists of a rotary blade that is movable forward and backward in a direction that crosses the table at right angles.

[Effect]

First, a frame material is placed on a table with the ruled surface facing upward, and the frame material is supported so as not to move relative to the table.

Next, when the lever gripped by the scoring device is pulled, the elevating body is lowered by the rotation of the eccentric disk, and the slider is moved forward (in the direction across the frame material) by the cam, so that the scoring tool can be applied to the frame material. As the cutting edge bites and moves forward, two cut lines are made in the frame material.

When the lever is returned, the slider retreats and the elevating body rises, so that the scoring blade returns to its original position.

Thereafter, by repeatedly moving the table, a cut is made between both ends of the frame material.

In addition, use a chisel to carve square holes between the cuts in the frame material taken from the table.

Further, after unloading the frame materials, the required number of muntin materials are placed on the table in a parallel manner, and the materials are prevented from moving with respect to the table.

Then, notches are sequentially cut into the material by moving the rotary blade in the front-back direction and moving the table in the lateral direction.

Since the cutting position of this notch is the same as the position of the scoring device, the positions of each end of the muntin material assembled by fitting the notches of the material coincide with the square hole machining position.

〔Example〕

In the figure, reference numeral 1 denotes a table that moves at every set pitch in the horizontal direction (left and right in Figure 1).

The method for moving the table 1 is to engage the pinion 3, which is rotatably supported in a fixed position on a rack 2 provided on the entire length of the lower surface of the table 1, and to connect the drive motor of the pinion 3 to a microcomputer. There are two methods: a method in which the table is operated by a slider intermittently to slide a set length, a parallel rail is provided on the outside of the rear edge of the table, and each stopper that regulates the amount of table movement is provided on this rail so that the position can be adjusted. The table is provided with an engagement piece that is released upward when passing over the stopper and then pushed down to engage with the stopper after passing, and the pinion is driven while turning the handle manually.
There are methods such as stopping the table at a fixed position (not shown).

It consists of a slider 6 provided to move in the direction, and two left and right scoring blades 15 supported on the lower surface of the slider 6. As the elevating body 4 moves up and down, the scoring blades 15 are bitten by the opponent, and then The slider 6 is moved forward to make a cut using the scoring blade 15.

Reference numeral 7 denotes an eccentric disk rotatably attached to the front surface of the elevating body 4 via a horizontal support shaft 8. A trochanter 9 pivotally supported on the support member 5 is in contact with the upper peripheral edge of the eccentric disk 7. There is.

The above-mentioned elevating body 4 is given a rising ability by a spring 10 so as to press the eccentric disk 7 against the trochanter 9.

Reference numeral 11 denotes a cam provided on the front surface of the eccentric disk 7, and a rotor 12 pivotally supported by the slider 6 is in contact with the cam 11.

The slider 6 is given a retractability by a spring 13 so as to press the trochanter 12 against the cam 11.

In the illustrated case, the eccentric disk 7 is a perfect circle whose center is pivoted, with a part of its periphery cut out, and the elevating body 4 is lowered until the trochanter 9 is transferred from the notch to the periphery, and is not lowered thereafter. It's getting old.

In addition, the cam 11 is arranged on the slider 6 by the inclined surface.
is moving forward.

14 is a lever that rotates the eccentric disk 7.

Further, on the lower surface of the slider 6, two scoring blades 15, 15 are provided, which are opposed to each other with a predetermined interval left and right, and whose cutting edges are directed downward.

The above-mentioned scoring blades 15, 15 have a rotating shaft 17 with a camera 16 that rotates in a fixed position in the illustrated case, and left-handed and right-handed screws provided from the center of this rotating shaft 17 to both ends. part 18, and a pair of female threaded bodies 19 screwed into both threaded parts 18 so as to stop rotation and slide.
Then, by screwing in the screw shaft 21 having the hole 20, the screw shaft 21 is pressed against both female screw bodies 19, and the female screw body 19 is pressed against both female screw bodies 19.
Since a push plate 22 is provided to prevent the swinging of the push plate 22 and is bolted to both female threaded bodies 19, the opposing distance can be freely adjusted by rotating the rotating shaft 17.

Note that by allowing the support member 5 to be moved and adjusted in the front-back direction, the position of the beginning of the marking can be changed.

23 is a rotary blade provided so as to be able to move forward and backward across the table 1.

In addition, in the case shown in the figure, the rotary blade 23 is provided with a slider 25 that slides in the front and back direction together with two shaft members 24 passed through the stationary body 34, and the slider 25 is fitted with a dovetail groove and a protrusion. An elevating body 29 is provided which is guided in the vertical direction by mating and can be raised and lowered by a male screw 27 with a handle 26 and a female screw 28 screwed into this male screw 27. A support member 5 that slides vertically using the rail 30 as a guide is provided, a rotary blade 23 driven by a motor 31 is installed on this support member 5, and both ends of a cylinder 32 are connected to the support member 5 and the elevating body 29. Therefore, when the gripping member 33 is gripped and the slider 25 is moved forward, a groove b is cut in the muntin material B by the rotary blade 23, and as the slider 25 retreats, the support member is If the rotary blade 23 is raised together with 5,
The rotary blade 23 prevents the groove b from being cut again.
Note that after the slider 25 stops retreating, the cylinder 32 is contracted to move the rotary blade 2 together with the support member 5.
Lower 3.

Further, by raising and lowering the elevating body 29 by operating the handle 26, the height of the rotary blade 23 can be freely adjusted.

The marking device according to this invention has the above-described configuration, and first, the frame material A is placed on the table 1 (supported so that it does not move).

Next, when the lever 14 is pulled, the rotation of the eccentric disc 7 causes the elevating body 4 to be lowered via the trochanter 9 that is in contact with the eccentric disc 7, and the scoring blades 15, 15 are applied to the frame material A. let them get involved.

On the other hand, since the slider 6 is advanced by the cam 11 via the rotor 12 that is in contact with the cam 11,
Two cuts a, a are made in the frame material A by the cutting blades 15, 15.

Next, when the lever 14 is returned, the slider 6 retreats and the elevating body 4 rises, so that the scoring blade 15 returns to its original position.

Then, the table 1 is slid so that the next marking device is exposed below the marking blade 15.

After machining the cut a as described above and removing the frame material A from the table 1, a large number of materials B arranged in parallel are placed on the table 1, and the table 1 is This prevents material B from moving.

Next, grip the gripping member 33 and slide the slider 25.
When the material B is pulled in, the rotary blade 23 creates a groove b in the material B.
is cut.

Thereafter, the slider 25 is pushed back and the table 1 is moved to bring the next groove cutting position onto the line of movement of the rotary blade 23.
