Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention is based on the operation of the plate thickness adjustment device in a super finishing planer equipped with a plate thickness detection device. This relates to a protective cover provided to prevent external force from acting on the adjustment piece that adjusts the point. be.

0002

[Conventional technology]

Conventionally, a planer blade and a material feeding device driven by an electric motor were installed vertically facing each other. The girder super finishing planer has a switch that detects the thickness of the wood to be cut. , the operating point position of the switch is adjusted using the adjustment piece, and the planer blade and material feeding device are adjusted properly. By setting appropriate intervals and feeding the wood, the wood is fed by the wood feeding device and then the planer blade The wood surface is finished by cutting. As shown in FIG. 3, since the adjustment piece 9 protrudes from the outer frame of the main body, The adjustment piece 9 moves due to external force, and the initially set operating point of the detection switch 8 changes. The machine detects the thickness of the wood while it is still in place, and then sets the distance between the planer blade and the material feeding device. child As a result, the proper distance between the wood and the wood cannot be obtained, resulting in poor material feeding and a marked decline in the finish of the cut surface. Was.

[Problem that the idea aims to solve]

As mentioned above, the plate thickness detection device has an adjustment piece located at a position that protrudes from the outer frame of the main body. In conventional super-finish planing machines with When external force is applied, the adjustment position of the adjustment piece moves and the operating point of the switch remains unchanged. To detect the thickness of the wood and set the distance between the planer blade and the material feeder, If the appropriate spacing between the timber equipment cannot be maintained and the spacing is narrow, apply pressure to the timber to obtain a good finished surface. If the gap is wide, the pressure necessary for feeding and cutting the material cannot be obtained, which may cause material feeding defects. It was the cause. The purpose of this invention is to prevent the above-mentioned problems caused by poor wood feeding and deterioration of the cutting surface. The movement of the adjustment piece of the thickness detection device due to external force is suppressed, and furthermore, the movement of the adjustment piece of the thickness detection device is suppressed by a means for suppressing the movement. The purpose is to ensure that the workability of adjustment work is not impaired.

0004

[Means to solve the problem]

The above purpose is to install an adjustment piece on the outer frame of the main body to adjust the operating point of the switch that detects the plate thickness. It is stored in a recessed part, a protective cover is provided in the storage part, and the locking structure of the protective cover is magnetically attached. This is achieved by making it possible to hold it by the action of force or elastic force such as a spring. Ru.

[0005]

[Effect]

A super finishing planer with a protective cover for the plate thickness detection device configured as above is , open the protective cover and operate the adjustment piece before detecting the thickness of the wood, and then set the plate at the appropriate position. Adjust the switch so that it operates, and close the protective cover after adjustment. In this state, place the wood below the switch and feel the thickness of the wood using the switch. Set the distance between the planer blade and the material feeding device, and rotate the material feeding device via the electric motor. Cutting and finishing the surface of wood with a sharp blade. During cutting work, the external force applied to the plate thickness detection device by wood etc. only acts on the protective cover. , the operating point of the switch does not change. Therefore, the planer blade and material feeding device should be used properly. Good material feed and cutting surface can be obtained by setting at intervals. Also, when adjusting the adjustment piece, Opening and closing operations can be performed without using any tools, so work efficiency is not compromised.

【Example】

An embodiment of the present invention will be described with reference to FIGS. 1 and 2. In the figure, the table 3 is fixed on the base 4, and the longitudinal direction of the table 3 is A planer blade 5 is provided in the center of the cylinder, and a plane is vertically slidable vertically opposite to the planer blade 5. The head 1 is provided with a material feeding device 2 rotatably via an electric motor (not shown). It is possible to support the wood and transport it. A roller support member 7 is provided on the wood feeding side of the head 1 so as to be rotatable in the vertical direction. One end of the roller support member 7 is pivotally supported by the head 1, and the other end is equipped with a detection roller for detecting wood. A detection switch 8 is fixed to the upper surface of the roller support member 7, and a detection switch 8 is fixed to the upper surface of the roller support member 7. is rotatably provided with an adjustment piece 9 that can come into contact with the detection switch 8, and a head is attached to the adjustment piece 9. An adjustment dial 10 is fixed to a recessed portion of the outer frame of the dial 1. Above adjustment dial 10 A rotatable protective cover 11 is provided on the head 1, and the protective cover 11 is attached to the head 1. It is supported by the head 1 by the magnetic force of the fixed magnet 12. The adjustment pieces that adjust the operating point of the switch are adjustment piece 9 and adjustment dial 10. It is made up of In the above configuration, the wood is positioned below the detection roller 6, and the head 1 is slid downward. The movement detection roller 6 is brought into contact with the wood. When the detection roller 6 comes into contact with wood, the roller support The holding member 7 is moved upward, and the detection switch 8 fixed to the supporting member 7 is also moved upward. move it. The detection switch 8 can be set to any position using the adjustment dial 10. The thickness of the wood is sensed by contacting the adjusting piece 9 that has been adjusted. Head 1 based on wood thickness detection signal The downward sliding movement of the lumber stops, and a lumber feeding path is formed between the planer blade 5 and the lumber feeding device 2. The contact position between the adjustment piece 9 and the detection switch 8 is determined by rotating the adjustment dial 10. If the distance to contact is short, the distance between the planer blade 5 and the material feeding device 2 can be adjusted by They spread out, and the farther they are, the smaller the distance between them. Adjustment of the adjustment dial 10 is performed using a protective cover supported by the magnetic force of a magnet 12. It can only be adjusted when 11 is opened.

[0007]

[Effect of the idea]

According to the present invention, the distance between the planer blade and the material feeding path by the material feeding device is adjusted by adjusting the adjustment dial. It is set by changing the contact position of the adjustment piece and the detection switch by operation. The two adjustment dials can only be operated when the protective cover is opened. Therefore, no external force is applied to the adjustment dial during cutting or feeding wood, etc. Since the contact position between the adjustment piece and the detection switch does not change, there will be no material feeding defects or deterioration of the cutting surface. This allows stable cutting at all times. In addition, even when operating the adjustment dial, the protective cover can be removed without using any tools. can be opened and closed without compromising the efficiency of adjustment work.
