Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for continuously cutting wood, in which cutting is performed continuously.

Conventionally, wood cutting equipment that feeds material onto a table equipped with a force adjustment device, reciprocates the material by switching the rotation of a material feeding member, and cuts the material in either one direction or in both directions is a work in progress! Although it is known from the publication No. 0-79090,
With this kind of material, the material is sent out in one round trip. However, the material surface cannot be finished neatly in one round trip,
In many cases, it is necessary to make three or several reciprocations, so the fed material must be returned to the machine two or several times, so the work is labor-intensive and inefficient. With this device, when the material becomes thinner during cutting, unless the material is applied to the pressure amount setting means using a limit switch and the pressure amount is reset, the material pressing force by the material feeding member will be insufficient and the material will be fed. If there is a defect or the material feeding direction is changed,
Due to illumination, the material may fly out, making it necessary to interrupt the cutting operation and frequently set the amount of pressurization, which has the drawback of greatly reducing work efficiency.

The method related to the present invention has been carried out to overcome the above-mentioned drawbacks, in which the material is repeatedly cut back and forth to perform continuous cutting, and the thickness of the material is reduced with each cutting. Then, the object of the present invention is to provide a device that allows highly efficient wood cutting to be continuously carried out in an unmanned operation by feeding out the material feeding member in accordance with the above, applying appropriate pressure to the material feeding member at all times.

Next, a wood cutting device suitable for carrying out the method according to the present invention will be described below with reference to the drawings.

1 in the figure is the machine body, a table 2 is provided on the top of the machine, and a groove 3 is provided in the center of the tee and pull 2 obliquely to the material feeding direction as shown in Figure 2 of the drawing. 3. Fit a sliding combination 6 with blades 4 and 5 mounted in opposite directions, and link this coupling 61 with a binion rack or other reciprocating means 8 driven by a motor 7, or Or, as shown in Figure 3 of the drawing
As shown, a circular groove 9 is provided in the center of the table 2,
A rotary holder 12 to which a cutter 11 is attached is fitted using the recessed groove 9# knife stock 10, and a rotating means 14 of a pinion gear molten metal driven by a motor t3t is linked to the rotary holder 12. Reference numeral 15.15 denotes a column erected on one side of the table 2, which supports an elevating body 16 projecting above the table 2 so as to be able to rise and fall freely, and a pair of rollers 17 and 18 are pivotally supported at the front and rear of the elevating body 16. Then, a belt-type material feeding member 19 is provided over the second rollers 17 and 18, and the material feeding member 19 is rotated in forward and reverse directions by a motor 20. Reference numeral 21 denotes a screw-type automatic feeding means linked to the elevating body 16, which is rotated by a motor 22.
The processing gap between the material feeding member 19 and the table 2 is adjusted. Reference numeral 23 denotes a material thickness detector such as a limit switch installed on the front side of the elevating body 16, which is turned on by the operator 24 to output a material detection signal when the material feeding member 19 is lowered at the top surface speed of the material. 25 is a material end detector such as a phototube installed on both sides of the table 2 corresponding to the approximate center of the material feeding member 9. be. 26 is a switch for setting the number of reciprocations installed on the control panel 27 of the wood cutting machine.
(2), the key is set to /times, the key (2) is set to 2 times, the key (2) is set to 3 times, the key (2) is set to q times, the key (2) is set to 5 times, and inputted to the controller described later. Reference numeral 28 denotes a cutting state selection switch provided on the control panel 27, which has keys ■ to ■. (2) sets row cutting in a reciprocating path, (2) sets compound cutting in which several rounds of rough cutting and finishing are performed, and (2) sets reciprocating cutting to cut the material in both directions, and inputs them to the controller described later. A timer 28 is activated by the detection signal t of the material end detector 25, and switches the rotation of the material feeding member 19 before the material end comes off from the material feeding member 19, thereby ensuring that the material is transported forward and backward. Is it going to be done? It is strained.

a is the detection signal of the detectors 23 and 26 and the setting switch 2
The motor 2 receives the selection signal 7 and drives the material feeding member 19.
0. It operates the heavy electric parts that control the operation of the motor 22 that drives the automatic feed means 21, the motor 7 or 13 that drives the sliding mixer 6 or the rotary payload 12, and uses a known microcomputer and sequencer Ql. be.

Next, to carry out the method of the present invention using the apparatus described above,
In the case of a material that requires one-way cutting to prevent the back grain phenomenon, the reciprocating circuit setting switch 26 provided on the control panel 27, for example,
Selecting the key and ■ sets the number of reciprocating times to 6, and selecting and operating the key ■ of the cutting state selection switch 28, for example, selects return cutting in reciprocating feed material, in this case 7 times in /reciprocating. Only material is cut.

Therefore, in this case, the controller a operates the automatic feeding means 21 to feed out the material feeding member 19 when the material has made two reciprocations. Once the settings are completed, the material feeding member 19 is started and the material is fed into the machining gap between this and the outer pipe/I/2. 25, the detector 25 detects this, activates the timer 28, temporarily stops the material feeding member 19 before the end of the material comes off the material feeding member 19, and reverses the material. The material is then returned and the material is cut for the 1st time by the blade 51 at this time. When the end of the material being scraped off comes off the detector 25, the detector 25 activates the timer 28, and when the cutting of the material is finished, the material feeding member 1
9 is temporarily stopped and then rotated forward, the material is fed out again, and before it comes off the material feeding member 19, it is returned by reversing the material feeding member 19 and is cut a second time by the cutter 5. Once finished, the material feeding member 19 stops once and then reverses.
During this temporary stop, the controller a drives the automatic feeding means 21, feeds out the material feeding member 19 by an amount corresponding to the decrease in material thickness due to cutting, applies an appropriate amount of pressure to the material feeding member 19, and controls the subsequent reciprocating material feeding. This is done reliably, and by repeating this back and forth, cutting is performed 3 times, 1 times, 5 times, and 6 times in sequence. During this time, the controller a controls the feeding means every time the cutting is performed twice. 2
The material feeding member 19 is fed out by 1 t, and the material feeding member 19 is
The amount of pressure applied is always maintained at an appropriate level, and the material is reliably fed many times to ensure continuous cutting of the material.

In addition, in the case of materials that can be cut back and forth because there are few occurrences of back-grains, cutting can be done both on the way out and on the way back, so the same 6 cuts as mentioned above will be done in 3 rounds of the material. , In this case, press the key ■ of the round trip number setting switch 26.
is operated to set three reciprocations of the material, and the key ■ of the cutting state selection switch 28 is operated to select reciprocating cutting. Then, the controller a causes the feeding means 21 to feed out the material feeding member 19 once per reciprocation of the material, so in this setting state Be, the controller a operates the material feeding member 19 to move the material into the machining gap. When the material is supplied, the material is reciprocated by the material feeding member 19, and is cut twice by the blades 5 and 6 during the going back and forth, and accordingly, the controller a feeds out the material feeding member 19 from the feeding means 21#. However, in this case as well, the material feeding member 19 is always given an appropriate amount of pressure to ensure repeated reciprocating material feeding, thereby ensuring continuous and excellent reciprocating cutting of the material.

Note that the above-mentioned action also applies when the material is repeatedly cut, that is, when the material is first rough cut several times and then finished cut, the material feeding member 19 is temporarily stopped seven times every time the material is cut twice. In this case as well, an appropriate amount of pressure is always applied to the material feeding member 19 to ensure reciprocating material feeding, so that compound cutting of the material can be performed continuously and satisfactorily.

As mentioned above, the method according to the present invention involves supplying the material onto a table that has been split open, and repeatedly reciprocating the material by switching the rotation of the material feeding member to perform continuous cutting by the delivery, while cutting the material. When the amount of material decreases, the automatic feeding means is used to repeatedly scrape the material to ensure reliable material feeding, so if the material is inserted into the processing gap of the cutting device, the material will be transferred to the material feeding member. When approaching the end of the material, the rotation of the material feeding member is changed and the material is moved in the opposite direction, so it is reciprocated through the machining gap, during which one-way or both-way cutting is continuously performed. When the cutting is completed, the material is fed out from the machining gap, and no human intervention is required during this time, resulting in significant labor savings and increased efficiency. Repeat the material cutting 1
Accordingly, when the thickness is reduced, the material feeding member is fed out by the automatic feeding means, and the amount of material pressurization of the material feeding member is automatically maintained at an appropriate level at all times. Even during these repeated back and forth movements, the material is reliably and stably transferred, and there are no problems such as poor material feeding due to insufficient pressure, material flying out due to illumination due to direction changes, or material sticking due to excessive pressure. This has the unique effect of not causing any sagging, wear and tear on the material feeding member, or redundant power costs.
