Abstract

PURPOSE:To simply adjust the optical axis position of a light detection sensor until the incidence and blocking of the light from a light projection sensor with respect to the light detection sensor are confirmed by two measuring devices allowed to correspond to the height of a setting gauge by setting a lift frame so that the leading end of a dial gauge comes into contact with the edge of a planer blade by raising and lowering the lift frame. CONSTITUTION:The dial gauge preset to a predetermined height by a setting gauge is placed on the upper surface of a table 2 and a lift frame 19 is moved up and down until the leading end of the dial gauge comes into contact with the edge of the planer blade positioned just under a planer spindle 5 to set the height from the edge of the planer blade to the upper surface of the table 2 to the height of the setting gauge. Next, a measuring device A is placed on the upper surface of the table 2 and the incident of light on a light detection sensor is confirmed and, subsequently, the measuring device A is replaced with a measuring device B to confirm the blocking of light. The optical axis positions of the light detection sensor 13 and a light projection sensor 12 are adjusted in height until the incidence or blocking of light by detaching or attaching a liner 16.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adjusting method for aligning the optical axis position of an optical sensor with the cutting edge of a planer blade in an optical sensor for measuring material thickness used in a table-fixing planer.

[0002]

2. Description of the Related Art The conventional method for adjusting the position of an optical sensor for measuring material thickness is to first cut the material with a planer blade, measure the size of the cut material with a tape measure, calipers, etc., and adjust it to the measured value. By repeating the work of adjusting the position of the optical sensor, the optical axis position of the optical sensor was adjusted.

[0003]

In the conventional optical sensor position adjusting method, it is necessary to repeatedly cut the material and adjust the optical axis position of the optical sensor many times until the dimensions are matched, which is very difficult for the position adjustment. It took time. Also, if the cutting dimensions vary due to material warpage or undulation,
It was difficult to accurately align the cutting edge of the planer blade with the optical axis of the optical sensor. An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to easily and accurately align the cutting edge of the planer blade and the optical axis position of the optical sensor.

[0004]

The above-mentioned object is to place a dial gauge, which is set to a predetermined height by a set gauge, on a table, and to elevate and lower the elevating frame so that the tip of the dial gauge and the cutting edge of a planer blade. The elevating frame is set at the position where the abutment is made, and the two types of measuring tools A and B corresponding to the height dimension of the set gauge are used. It is confirmed that the light is emitted and is shielded by the measuring tool B. If the light is not received or is not shielded, the position of the light emitting and receiving light sensor is adjusted by the adjusting means until the light is received or the light is blocked. This is achieved by aligning the position of the cutting edge of the blade with the optical axis of the optical sensor.

[0005]

[Function] First, the dial gauge set to a predetermined height by the set gauge is placed on the table upper surface where the planer blade is located, and the elevating frame is moved up and down to the position where the tip of the dial gauge comes into contact with the blade tip of the planer blade. Set the height from the cutting edge of the planer blade to the table upper surface as the height dimension of the set gauge. With respect to the height from the cutting edge set to a predetermined value to the table top surface, the measuring tool A is placed on the table top surface in order to confirm the position of the light emitting and receiving light sensors, and the height of the measuring tool A Make sure the light comes in. next,
Replace the measuring tool A with a measuring tool B that is slightly smaller than the measuring tool A, and check whether the light of the optical sensor is blocked at the height of the measuring tool B. The position of the optical axis of the optical sensor is adjusted by the adjusting means until the light or the light is blocked so that the position of the optical sensor is within the difference in height between the measuring tools A and B.
