Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a cutting amount correcting device for a wood cutting device, for accurately matching the cutting amount to a required cutting amount.

<Prior art> In a conventional wood cutting device, a cutter is placed beside the travel path of the processed material so that its movement can be adjusted, and the cutter is adjusted in movement based on a scale that is a mark of the amount of movement. This made it possible to cut the workpiece to the required finishing dimensions.

Incidentally, even if the scale accurately indicates the distance between the guide surface of the workpiece and the cutter, the J zo of the cut workpiece is not necessarily equal to the set interval.

This is mainly due to the following reasons.

b) The wood is compressed by the material feeding device, and the compression steepness differs depending on the material of the wood, so the cutting thickness changes minutely every time the material of the processed material is changed.

■The amount of cutting varies depending on the feeding speed of the material and, if the cutter has a rotating blade, changes in the rotational speed.

c) Cutting amount varies due to cutter wear and cutter polishing.

Therefore, after changing the workpiece to be applied or making various adjustments, it is necessary to always inspect the finished dimensions of the workpiece and correct the cutter position.

<Problems to be Solved by the Invention> By the way, in the conventional configuration, the position of the cutter is moved by an L-cut operation, and adjustment is made using the scale as a reference.

Assuming that the finished dimension is 100.0 rin layer inside the work body,
First, the cutter is moved and the scale is set to the too and o* layers, and the workpiece is trial cut. As a result, if the cutting thickness is 101.1 layers, then the cutter is placed at the scale position of 98.9 layers, which is the difference of 11 meters from the cutting dimension of 100.0 layers. Move to compensate. Thereby, a processed material having 100.0 layers of finishing method can be obtained.

However, according to this procedure, the movement of the cutter is adjusted by the L movement, which is cumbersome. In addition, it is necessary to calculate the difference between the cutting thickness and the finished dimension, and then subtract the calculated value from the scale for adjustment, which is complicated, and the correction work is performed frequently, making it troublesome. At the same time, it is naturally easy to miscalculate.

This has been a cause of incorrect setting of the cutter position.

The object of the present invention is to provide a cutting amount correction device that can easily carry out such correction work.

Means to solve problems〉 The present invention is arranged beside a travel path for processed materials.

a cutter whose distance from a reference position can be variably adjusted by a moving motor; a counter that counts the amount of movement of the cutter; and a current position display section that displays the current distance between the cutter and the reference surface. and a target value display section that displays target dimensions.

and a numerical input switch for setting numerical values on each of the display sections.

Driven by the start switch, it calculates the difference between the current distance from the reference position of the cutter and the target dimension manually input to the target value display section, sets the counted value on the counter, and drives the moving motor. , a drive control means for stopping the moving motor in response to a count value extinguishing signal from a counter; and a current value setting switch for displaying an input value from a numerical manual switch on a current value display section.

Here, [1 standard dimension] is a concept that includes both the cutting target dimension and the finishing method.

Effects> As described above, the case where the width dimension is 100.0 mm will be explained.

First, the value l'100.0.1 is input using the input switch, and the value is displayed on the target value display section. At this time,
The current value display shows the position adjusted in the previous cutting process.

The distance between the current cutter and the reference position is displayed.

Next, the start switch of the drive control means is turned on.

As a result, the moving motor is driven, the value displayed on the current position display section is corrected based on the counting function of the counter, the display becomes i'loO, Qj, the moving motor is stopped, and the cutter is positioned. Ru.

After this, trial cutting of the processed material is performed and its thickness is measured.

If this thickness is 101.1m layer and correction is required, turn on the current (ff setting switch and input the number ((i) into the current position display section using the input switch. At this time, the target value display section shows F Ioo.

The value 01 remains displayed.

After the end of the manual effort, the start switch is turned on, the moving motor is driven, and the cutter is moved closer by 1.1 layer, which corresponds to an 11 ifr difference. By executing this drive control means, when the movement is achieved, floo, 0.1 is displayed on the current position display section and the target value display section.
Completion of the correction is visually confirmed.

In the above procedure, the operator first inputs the finished dimensions of 1"loO, Oj in the target value display section, and when making corrections, inputs the value of the thickness of the sample-cut workpiece in the current position display section. All you have to do is input it as is, and no arithmetic calculation is required.
