Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a chip breaker device for an automatic plane, which suppresses lifting of a member to be cut due to a reaction force of cutting.

[Conventional technology]

In the case of cutting in an automatic plane which is provided with a feeding member for transferring a member to be cut and a storage member provided with a plane, and a table facing the material feeding unit and forming a feeding path between them. ,
Due to the cutting reaction force, the material to be cut such as wood floats and develops.

In order to suppress this, a plurality of chip breakers, which are held slidably in the vertical direction by a holding member, are arranged in parallel at right angles to the transfer direction of the member to be cut, adjacent to the plane in the storage member. The member to be cut is pressed downward.

As a method of supporting the holding member, normally, in order to downsize the device and reduce the cost, the holding member is fixed directly to the storage member, but in large high-class machines, the holding member is a guide member for discharging chips. When the chip breaker stops moving up and down due to the accumulation of chips, the guide member rotates upwards,
There are those that retract the chip breaker to avoid stopping the transfer of the member to be cut due to abnormal pressing, or those that rotatably support the holding member on the bearing of the plane. is there.

[Problems to be solved by the device]

In the conventional technology, the gap between the chip breakers is made as small as possible by high precision machining.
Chips intrude through minute gaps and adhere to the side surface of the chip breaker or accumulate on the fitting part and lower part.

Therefore, when a cutting operation is performed for a long time, the vertical movement of the chip breaker gradually becomes heavy and finally becomes inoperable.

In the conventional device in which the holding member is fixed to the storage member, in this case, the member to be cut receives an abnormally large pressing force between the chip breaker and the table and stops the transfer, so it is necessary to take measures to avoid this. .

It should be noted that large high-class machines and the like have a structure in which the holding member is rotated to avoid the stoppage of the transfer as described above, but the size of the apparatus becomes large and the cost becomes high.

The present invention solves the drawbacks of the prior art, avoids stopping the transfer of the cut member even if the vertical movement of the chip breaker is obstructed due to the accumulation of chips, etc., and has a simple structure, downsizing and cost reduction. It is an object of the present invention to provide a chip breaker device for an automatic plane that can be used.

[Means for Solving the Problems]

In the present invention, at the end of the storage member provided with the material feeding means and the plane body,
It is characterized in that a supporting mechanism for supporting a holding member for holding the chip breaker slidably in the vertical direction is provided, and an elastic member for pressing the holding member downward is interposed in the supporting mechanism.

[Action]

In the present invention, the chip breaker is held by the holding member so as to be slidable in the vertical direction, and suppresses the cutting reaction force generated on the member to be cut during cutting. The holding member is supported by the support mechanism of the storage member and is pressed downward via the elastic member.

If the vertical movement of the chip breaker is hindered by the accumulation of chips and the like, and the pushing force of a predetermined amount or more acts on the chip breaker, the holding member is pushed up, and it is possible to avoid stopping the transfer of the member to be cut.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of an automatic plane according to this embodiment, in which 1 is a base, 2 is a table on which a member to be cut is placed,
A column 3 for supporting the table 2 is provided on the base 1, and 4 is an elevating screw, 5 is a handle, and the table 2 can be moved up and down by an elevating screw 4 by operating the handle 5.

Reference numeral 6 denotes a storage member disposed above the table 2 and supported by the column 3, 7 denotes a pair of rollers for transferring a member to be cut, and 8
Is a plane member arranged between the left and right rollers 7, and 9 is for cutting
A chip breaker that suppresses the cutting reaction force generated in the member to be cut,
Reference numeral 10 denotes a holding member for holding the chip breaker 9, and a feeding path is formed between the table 2 and the feeding means constituted by the feeding roller 7 installed inside the storage member 6. The plane 8 and the roller 7 are rotatably supported by a drive motor and a transmission device (not shown).

2 is a sectional view taken along the line AA of FIG. 1, FIG. 3 is a partial sectional view showing the inside of the storage member 6 in FIG. 1, and in FIG. 2 and FIG. Is a bolt fixed upright to the holding member 10, 13 is a spring wound around the bolt 12, and the plurality of chip breakers 9 are adjacent to each other in a direction perpendicular to the transfer direction of the member to be cut 11. Are arranged in parallel. Then, the chip breaker 9 is held by the holding member 10.
The bolts 12 are individually fitted and independently held slidably in the vertical direction, and are pressed downward by springs 13.

A support mechanism 14 supports the holding member 10, and is composed of a bolt 15 fixed to the end of the storage member 6 and a spring 16 wound around the bolt 15. Both ends of the holding member 10 are fitted into the bolts 15 and are slidable in the vertical direction.
The spring 10 is pressed downward by the spring 16.

In the above configuration, the table 2 is moved up and down by operating the handle 5 to set the cutting height, and then the feed motor roller 7 and the plane barrel 8 are rotated by the rotation of the drive motor.

The member to be cut 11 moves on the table 2 by the rotation of the feed roller 7, and the tip of the chip breaker 7 is the member to be cut.
When it comes into contact with the upper surface of 11, the chip breaker 7 is pushed up by the elastic force of the spring 13 and presses the member 11 to be cut downward.

The member to be cut 11 is cut by the rotation of the plane body 8, and the chips hit the chip breaker 9 and are discharged along the side surface in the direction of arrow B in FIG. 3, but some of the chips are between the chip breakers 9. It intrudes through the gap and is deposited on the lower portion of the fitting portion of the chip breaker 9 that fits into the holding member 10.

Therefore, the vertical movement of the chip breaker 9 becomes heavy, and when a pushing force of a predetermined amount or more acts on this, the spring 16
Holding member supported slidably in the vertical direction via
10 is pushed up and the elastic force of the spring 16 presses the member 11 to be cut downward.

Thus, according to this embodiment, the chip breaker 9
When there is a problem in the vertical movement of the holding member 6, the support mechanism 14 of the holding member 10 provided in the storage member 6 can be operated to continue the cutting work, and the stop of the transfer of the member to be cut 11 can be avoided.

Further, since the support mechanism 14 is provided at the end of the storage member 6,
While the structure is simple and the device can be miniaturized, it can be provided at low cost because only the spring 16 is added.

[Effect of device]

According to the present invention, the disadvantages of the prior art are solved, and even if the vertical movement of the chip breaker is hindered due to the accumulation of chips, it is possible to avoid stopping the transfer of the member to be cut, and with a simple structure,
It is possible to obtain a chip breaker device for an automatic plane which is capable of downsizing and cost reduction.
