[0004]

By the way, as a matter of course, both the forward plane blade and the return plane blade are uniformly worn by the reciprocal cutting of the work material. Accordingly, the work material is completed by the relatively worst plane blade.

When one of the plane blades is retracted,
A concave surface is formed in a blade mounting groove formed in a material feeding table on which the plane blade is mounted. For this reason, due to the depressed surface, the support of the work material is lost at the corresponding portion, and there is a problem that a stable work material cannot be secured when the short work material is fed and cut.

An object of the present invention is to eliminate the problems of the conventional configuration.

[0007]

According to the present invention, a reversible sheet feeding device driven by a reversible sheet feeding motor and a sheet feeding table provided with a plane blade are opposed to each other so as to be relatively movable. In a woodworking super-finishing plane machine that reciprocates the work material repeatedly by the device, in the blade mounting groove formed on the material sending table,
A replane blade that protrudes the cutting edge to the rear and a forward plane blade that protrudes the cutting edge to the front are arranged, with both plane blades facing the feeding surface side of the feeding table, and the required lower edge of the tilting base. The inclined guide surface is formed along the width direction of the material feeding passage, and a movable support piece having an inclined support surface equiangular with the inclined surface is disposed directly below the inclined guide surface, and The edge is supported by the inclined support surface,
Further, a rack is formed on each of the movable support pieces along the width direction, and a pinion connected to the drive shaft of the tilt motors M3 and M4 is meshed with each rack, and the tilt motors M3 and M4 are formed.
By moving the movable support piece along the width direction of the material feeding passage by driving, the required lower edge of the tilting base is raised and lowered, respectively, so that the cutting edge of the forward plane blade protrudes from the material feeding surface, Outgoing cutting position where the cutting edge retreats from the feeding surface, and the re-cutting position where the cutting edge of the reshaping blade protrudes from the feeding surface, and the cutting edge of the reshaping blade retreats from the feeding surface. A tilt drive mechanism for tilt-converting the tilt base to a both retracted position where both cutting edges retreat from the sheet feeding surface, respectively, and drive-controls the tilt motors M3 and M4 to move the tilt base in one of reciprocating directions. In the reciprocating stroke, one of the planes is set to one of the cutting positions, and the reciprocating position is set to the both retracted positions. With the blade retracted in the reciprocating stroke, at or near the final stroke, the tilt base Reciprocating cutting woodworking characterized by comprising a drive control means for generating a feeding pattern in which, as the other cutting position, the other plane blade is made to protrude in a stroke for cutting the work material. It is a super finishing plane machine for use.

Further, in a machine having the same outward plane blade and return plane blade, the tilt motors M3 and M4 are drive-controlled to move the tilt base in the reciprocating stroke or one of the strokes. The present invention is characterized in that a drive control means is provided for generating a short work material feeding pattern in which both cutting edges of the blade and the replane blade are both protruded from the material feeding surface. Here, as this configuration, the tilt motors M3 and M4 are drive-controlled to move the tilt base in one of the reciprocating strokes so that both the forward plane blade and the re-plane blade have their respective feed surfaces. A short work material feeding pattern may be generated that is set to a forward cutting position or a backward cutting position where only one of the forward plane blade and the return plane blade is projected in the other stroke. . Furthermore, a front plane blade and a rear plane blade that protrude the blade in the same direction in either the front or rear are arranged in the blade mounting groove formed in the material feeding table, and both plane blades are driven by the front and rear drive devices. Is controlled to be converted into a position protruding from the material feeding surface and a position retreating from the material feeding surface, respectively.
3, the M4 is driven and the tilting base is set to one of the cutting positions in one stroke of the reciprocation, and
By setting both the retracted positions, one of the plane blades is protruded for each of the reciprocating strokes in which the work material is to be cut, and the other plane blade is kept retracted in the reciprocating stroke, and in the final stroke or in the vicinity thereof The tilt base, the other cutting position, the other plane blade is provided with a drive control means for generating a feeding pattern so as to protrude in the process of cutting the work material, Is what you do. In addition, in the one with the same front plane blade and rear plane blade, in the reciprocating stroke, both the front plane blade and the rear plane blade are maintained at the protruding position, or the work material in the reciprocating stroke Short work material feed with both the front plane blade and rear plane blade protruding position in the process that does not cut the work material, with both the front plane blade and the rear plane blade protruding position in the process that will cut the A device provided with drive control means for generating a pattern is proposed.

[0009]

[Effect] Regardless of whether it is equipped with a forward plane blade and a return plane blade, or with a front plane blade and a rear plane blade, one plane blade is used to cut the work material during the reciprocating stroke. In the feeding pattern that is converted to the protruding position for each different stroke and the other plane blade is kept at the retracted position during the reciprocating stroke,
The other plane blade does not contribute during the reciprocating stroke and cuts the workpiece only at or near the final stroke. For this reason, the cutting edge of the other plane blade is preserved in sharpness and contributes to cutting only in the final stage, so that the surface of the processed material can secure a good finished skin. At this time, the forward plane blade and the return plane blade, or the front plane blade and the rear plane blade, either one protrudes in one stroke, retreats both in the other stroke, and the other one protrudes in the last stroke. Although it is necessary to perform a simple operation, the provision of the above-described tilt drive mechanism allows quick and simple control by drive control of the tilt motors M3 and M4.

[0010] In a short work material feeding pattern provided with a forward plane blade and a return plane blade, in a process in which at least both plane blades are in the protruding position, a depressed surface due to retreat of the plane blade in the blade mounting groove. Does not occur, so that stable material feeding is possible. Furthermore, in the short work material feed pattern with the same front plane blade and rear plane blade, in the process to be cut, both the front plane blade and the rear plane blade will be in the protruding position, Even in the process of not cutting the work material, both will not be in the retracted position,
The depressed surface is reduced as much as possible, and stable feeding is possible.

[0011]

A reversible material feeder 7 is provided on the material feed table 2.
However, it is opposed to the base 1 via a material feeding passage. The reversible material feeding device 7 includes a lifting motor M that rotationally drives a lifting screw 8.
2 to move up and down along the guide posts 9, 9; The reversible feeding device 7 is configured by supporting a driving roll 11 driven by a reversible feeding motor M1 and a driven roll 12 back and forth, and extending a feeding belt 13 between the rolls 11 and 12. I have. Further, inside the lower running portion of the material feeding belt 13, there are arranged treading rolls 14 which are urged downward by springs or the like. These members are hidden by the frame cover 16. In addition, auxiliary tables (not shown) are provided on the entrance side and the exit side of the material feeding table 2.

In order to set the interval of the material feeding passage of the reversible material feeding device 7 with respect to the material feeding table 2 to an optimum value capable of applying an appropriate material feeding pressure to the work material, the reversible material feeding device 7 is provided at the inlet side of the reversible material feeding device 7. Is provided with a detection switch LS4. That is, the lifting / lowering operation piece 20 urged downward by the ridge 21 interposed on the upper portion is disposed in the frame cover 16.
The lifting operation piece 20 is supported by a receiving plate 22 that covers a roller supported at its lower end. The receiving plate 22 is rotatably supported by a support shaft 23, and is urged by a spring 24 in a direction in which the lifting operation piece 20 is supported. A detection switch LS4 is mounted on the upper end of the lifting / lowering operation piece 20, and the detection switch L
The detection end of S4 contacts the ceiling surface of the frame cover 16,
Thus, the on operation is performed.

On the other hand, the material feeding table 2 has a detection switch LS3 for detecting the supply of the work material at the entrance side thereof,
The detection switches LS1 for controlling the reverse feeding of the work material are sequentially arranged adjacent to each other. And the detection switch LS
Actuating pieces 26 and 27, one end of which is pivotally supported and the other end of which is urged upward by a spline, are attached to the first and LS3, and their curved edges slightly project from the material feeding guide surface f, respectively, as described later. When the processing material is supplied or passed and the protruding edge is pushed downward, the detection switches LS1 and LS3 are each turned on. Further, a detection switch LS2 for controlling the normal feeding of the work material is provided at the rear end of the material feeding passage. Similarly, the detection switch LS2 is pivotally supported at one end, and is urged upward at the other end by an ridge, and an operating piece 28 having a curved end protruding from the material feeding guide surface f protrudes. When pressed down, the detection switch LS2 is turned on.

A slit plate s is fixed to the drive shaft of a lifting motor M2 for raising and lowering the reversible material feeding device 7, and an encoder e for detecting the number of passages of the slit is provided. The drive amount of M2, that is, the amount of elevation of the reversible material feeding device 7 can be detected.

Further, a timer T for controlling the reversing position of the work material and a central control unit CPU constituting drive control means for controlling the driving of each motor are mounted on the super finishing plane machine.

Next, the structure of the tilt control means including the forward drive device X and the backward drive device Y for tilting the tilt base 30 according to the main part of the present invention will be described with reference to FIGS.

The rotary table 3 is provided with a blade mounting groove 6, a tilting base 30 is mounted on a base 37 of the blade mounting groove 6, and a plane table 4a, 4b is mounted thereon. .

A return stroke tilt motor M3 or a forward stroke tilt motor M4 is mounted on the front and rear portions of the rotary table 3 with its drive shaft positioned upward. A pinion 31 is fixed to the drive shaft via a torque limiter 32 for protecting the drive shaft from overload.

On the other hand, as shown in FIGS. 6 and 7, the inclined guide surfaces 34 extend along the width direction on the lower surfaces of both side edges of the tilt base 30.
Are formed. Under the inclined guide surface 34, wedge-shaped movable support pieces 35a and 35b supported by the base 37 are interposed. On the upper surfaces of the movable support pieces 35a and 35b, an inclined support surface 36 having the same angle as the inclined guide surface 34 is formed. Further, the movable support pieces 35a, 35b
A rack 38 is formed on a side surface of the pinion 31, and the pinion 31 is engaged with the rack 38.

The forward drive device X is constituted by the forward stroke tilt motor M4, the movable support piece 35a, the pinion 31 and the rack 38 which link the both, and the forward drive tilt motor M3 and the movable support The return drive device Y is constituted by the piece 35b, the pinion 31 and the rack 38 that link the two.

As a result, when the return stroke tilt motor M3 or the forward stroke tilt motor M4 is driven, the racks 38, 3
8, the movable support pieces 35a, 35b
7, the tilting base 30 supported by contacting the inclined support surface 36 with the inclined guide surface 34 by the guide action of the inclined support surface 36 of the movable support pieces 35a, 35b has an uneven height. One end is lifted by the position, and the lifting operation is performed.

The positions of the movable support pieces 35a and 35b are as follows.
As shown in FIG. 7, the edge is detected by the detectors S5 and S6, and is set by defining the movement amount. Actually, the amount of elevation at this end is about 2 mm.

By the above-described operation, as shown in FIG. 8A, when the tilting base 30 is tilted clockwise, the tip of the forward plane blade 5a projects from the material feeding guide surface f and the tip of the replane blade 5b is fed. It retreats downward from the material guide surface f and becomes the forward cutting position.

As shown in FIGS. 5 and 8B, the tilt base 3
When the counterclockwise tilt is 0, the cutting edge of the replane blade 5b protrudes from the material feeding guide surface f, and the tip of the forward plane blade 5a is retracted downward from the material feeding guide surface f to be the recutting position.

[0028] Similarly, as shown in FIG. 8 c, inversely driving the tilting motors M3 and forward stroke for tilting motor M4 for backward stroke, the position the movable support piece 35a, 35b are both detected by the detectors S ₆ As a result, the tilting base 30 is lowered, and the cutting edges of the forward plane blade 5a and the return plane blade 5b are both retracted from the material feeding guide surface f, thereby being in the retracted position.

Further, as shown in FIG. 8D, the tilting motor M3 for the return stroke and the tilting motor M4 for the forward stroke are driven so that the movable support pieces 35a and 35b are both tilted at the position detected by the detector S5. Both ends of the base 30 are pushed up, so that the leading edges of the forward plane blade 5a and the re-plane blade 5b are both protruded from the material feeding guide surface f.

As described above, in the above-described configuration, the tip positions of the forward plane blades 5a and the return plane blades 5b are related to the operation of the tilting base 30, but the projecting position and the retreat position of the forward plane blade 5a. The protruding position and the retreat position of the return plane blade 5b are determined only by the backward drive Y, and the forward drive apparatus X alone.

The upper limit position is defined by a stopper 39 formed on the lower edge of the side wall of the blade mounting groove 6 of the rotary table 3 in contact with the edge of the tilt base 30, so that the upper tilt cannot be performed.

Next, the operation of the basic feeding pattern of the reciprocating cutting type super finishing plane for woodworking having the above-described configuration will be described. This series of operations is controlled by the central control unit CPU constituting the drive control means of the present invention.

First, a work material is supplied onto the material feeding table 2. At this time, if the thickness of the work material is large, the tip of the work material tilts the receiving plate 22, pushes up the lifting / lowering operation piece 20, and the detection switch LS4 is turned on. Thereby, the lifting motor M
2 drives, the reversible material feeding device 7 rises, and accordingly, the detection switch LS4 is turned off. Then, a timer (not shown) is activated, and stops rising several seconds (predetermined value) after the return from the OFF state. This series of operations is for widening the material feeding path with respect to the thickness of the work material before performing the positioning operation of the next reversible material feeding device 7, and the stop time can be surely detected. This is set to secure the off position of LS4. Accordingly, when the material feeding passage is wider than the thickness of the work material from the beginning (when the detection switch LS4 is not turned on by the supply of the work material), such an operation is omitted.

After the provisional position of the reversible material feeding device 7 is set as described above or when the thickness of the processed material is small, the detection switch L
If S4 is not turned on, a work material is further charged. As a result, the operating piece 26 is pressed below the material feeding guide surface f, and the detection switch LS3 is turned on. Then, by turning on the detection switch LS3, in order to remove the influence of inertia due to the lowering of the reversible material feeding device 7, once the reversible material feeding device 7 is excessively lowered,
It is raised again to perform positioning.

After that, when the positioning of the reversible material feeding device 7 is completed, the normal feeding drive of the reversible material feeding device 7 is started, and the work material is normally fed. At this time, the tip of the outgoing plane blade 5a protrudes from the material feeding guide surface f, and the return plane blade 5b is retracted downward, and the work material is cut by the outgoing plane blade 5a in the forward stroke. . (See the position in Fig. 8a and Fig. 9a)

In the forward stroke, the detection switch LS1 is turned on by the advance of the workpiece, and when the detection switch LS1 is returned to the off position following the rear end of the workpiece, the timer T is activated. Then, the rear end of the processed material is cut by passing over the forward plane blade 5a, and the drive of the reversible material feeding motor M1 is stopped as the set time of the timer T is exhausted.

The return stroke is started with the expiration of the set time of the timer T. That is, as shown exaggeratedly in FIG. 8A, the tilt motor M3 is driven in the forward direction,
4 is driven in the reverse direction so that the movable support pieces 35a and 35
b move in the opposite directions, and one end of the tilting base 30 is lifted to the return tilt position, the cutting edge of the reverting blade 5b protrudes from the material feeding guide surface f, and the cutting edge of the forward plane blade 5a is It retreats downward from the guide surface f (see FIG. 9B).

After the conversion, the reversible feed motor M1 starts reverse feed driving. Then, the detection switch LS2 which has been turned on with the advance of the workpiece is returned to the off state,
The timer T is activated by this return to the off state, the lower surface of the work material is cut by the replane blade 5b, and the rear end passes over the replane blade 5b. After that, the drive of the reversible material feeding motor M1 is stopped.

Thereafter, the tilting motors M3 and M4 are driven again, and the tilting base 30 is tilted in the opposite direction to the forward inclined position (the position shown in FIG. 11), and the cutting edge of the forward plane blade 5a is moved to the material guide surface f. , And the reversing blade 5b is retracted downward, the reversible material feeding motor M1 starts normal feeding driving, and the forward stroke is started again.

As described above, the work material reciprocates and is sequentially cut by the forward plane blade 5a and the return plane blade 5b. In this process, when the thickness of the processed material is reduced by reciprocating cutting, the material feeding pressure is reduced. Therefore, as the predetermined finished skin is digested, the lifting motor M2 is driven, and the reversible material feeding device 7 is lowered by a predetermined amount. Will be done. This lowering control is performed based on the signal output of the encoder e described above.

When the predetermined number of cuts has been exhausted, the front end (rear end of the work material) of the work material in the feed direction is detected by the detection switch LS.
3 is turned on and returns to off with the passage of the work material, the drive of the reversible material feed motor M1 is stopped, and
The cutting edge of the work material ends after the cutting edge of the forward plane blade 5a protrudes from the material feeding guide surface f and the cutting edge of the return plane blade 5b retreats downward and prepares for the next time.

The number of times of this cutting is determined by the upper and lower detection switches KS ₃ and KS ₄ for detecting the elevation of the reciprocating plane table 4 a and the return plane table 4.
Upper and lower detection switches KS ₁ , KS ₂ for detecting the elevation of b
It is counted for each operation (see FIG. 1).

As described above, the tilting motors M3 and M4 are timing-driven controlled by the central control unit CPU (drive control means) with the expiration of the timer T, so as to convert the forward and backward strokes of the workpiece. Accordingly, when the detection switch LS ₃ detects the blade edge of the work material with the plane blade conversion control for alternately tilting the tilt base 30 and the insertion of the work material into the material feeding passage, the reversible material feeding device 7 by driving the lifting motor M2, and Okuzai passage interval control for setting the height position of the reversible Okuzai device 7 on the position of the detection switch LS ₄ as a reference, while Okuzai initiated by the Okuzai passage interval setting, converts Okuzai direction of the reversible Okuzai device for each timed digest timer T, further with the expiration of the predetermined cutting times, the backhaul by the running direction rear end of the workpiece to be reverse feeding the detection switch LS ₃ detects Suspended sending system So that the bets are performed.

The above configuration shows the basic feed pattern in which the work material is cut by the corresponding plane blades 5a and 5b in the reciprocating stroke. It is possible to selectively execute the following feeding pattern indicated by reference numeral 10.

That is, in the above-described basic feeding pattern, the reciprocal cutting of the work material naturally causes the forward plane blade 5a.
And both the replane blade 5b are worn uniformly. The finished skin of the processed material also gradually deteriorates with the reciprocating cutting. Therefore, in the state where the cutting has been completed to the predetermined thickness, the cutting surface of the work material is relatively completed in the worst state in relation to the wear of the plane blade.

Therefore, a special feeding pattern as shown in FIG. 10 can be selected.

That is, in FIG. 10A, during the forward stroke, the forward drive device X (tilt motor M4) and the backward drive device Y (tilt motor M3) are drive-controlled to move the tilt base 3
8 in which only the outgoing plane table 4a rises, the cutting edge of the outgoing plane blade 5a protrudes from the material feeding guide surface f, and the cutting edge of the replaneting blade 5b retreats downward from the material feeding guide surface f. The cutting position. In the return stroke, as shown in FIG. 8C, in which the tilt base 30 is both retracted horizontally and lowered, the cutting edges of the plane blades 5a and 5b are both retracted downward from the material feeding guide surface f. And Due to the reciprocating movement during processing,
Cutting is performed only in the forward stroke, and only the cutting edge of the forward plane blade 5a contributes to the cutting and gradually wears.
And this wear deteriorates the sharpness.

Then, in the return stroke of the final process, the tilt base 3
0 tilts in the counterclockwise direction, and the cutting edge of the replane blade 5b of the replane table 4b projects from the material feeding guide surface f to be the re-cutting position shown in FIG. 8B, and for the first time, the re-plane blade 5b contributes to the cutting. Becomes The replane blade 5b is in a standby state when reciprocating after the supply of the work material, and therefore, its cutting edge is less worn than the forward plane blade 5a. For this reason, the return plane blade 5b
Has good sharpness, and the final cutting can be performed with good finish.

In FIG. 10B, contrary to the above, as shown in FIG. 8C, the cutting edges of the plane blades 5a and 5b are both retracted downward from the material feeding guide surface f in the forward stroke, and In the embodiment shown in FIG. 8B in which only the cutting edge of the replane blade 5b of the replane table 4b projects from the feed guide surface f, the work material is cut only by the replane blade 5b in the reciprocating stroke. Then, in the forward stroke of the final reciprocating stroke, as shown in FIG. 8A, the forward plane blade 5a is protruded and sharply finish-cut, and further, in the return stroke, the cutting is performed again by the reverse plane blade 5b. It was done. In such a configuration, in the return process of the final stroke, both the plane blades 5a and 5b may be retracted as shown in FIG.

By the way, in the state shown in FIGS.
When one of the plane tables is retracted, a depressed surface α is generated in the blade mounting groove 6 of the rotary table 3 as shown extremely in FIG. For this reason, the support of the work material is lost at the site due to the depressed surface α, and particularly when the short work material w is fed and cut, a stable material feed cannot be secured, and There is a problem that it is not possible to perform a complicated cutting process.

Therefore, the short work material feeding pattern shown in FIG. 11 is selected, and the central control unit CPU (drive control means)
Is executed by

Here, FIG. 11A shows a case where both the plane blades 5a and 5b project from the material feeding guide surface f in the forward and backward strokes, as shown in FIG. 8D. As a result, the work material is cut in the reciprocating stroke, and neither the plane tables 4a, 4b are retracted downward in the forward stroke, so that the depressed surface α is not generated, and therefore the short work material w is stably fed. You will get. In this case, only one plane blade contributes to the cutting, the other plane blade does not contribute to the cutting, and the short workpiece w passes through in a rubbing state.
Comparing the advantages and disadvantages as a whole, it is possible to excellently receive the benefit of the stable feeding of the short workpiece w.

FIG. 11B shows that the plane blade 5
a and 5b both protrude from the material guiding surface f in the two projecting positions shown in FIG.
5b is a mode of FIG. 8C retracting from the material feeding guide surface f. As a result, the short work material w
Is cut, and any plane table 4
Also, a and 4b do not retreat downward, so that a depressed surface α is not generated, so that the short work material w can be stably fed. On the other hand, in the return stroke, both the plane tables 4a and 4b are retracted downward. In this case, even if the feeding of the short workpiece w is unstable, the workpiece is not subjected to the cutting, so that it is not related to the deterioration of the cut surface. There is no problem.

As another short material feeding pattern, in the outward stroke, as described above, both the plane blades 5a and 5b are set to the both projecting positions in FIG. In the return stroke, either one of the plane blades 5a, 5b may be set to the retreat position as shown in FIG. 8A or 8B.

In this case, in the case where both the projecting positions in FIG. 8D are set in the forward stroke and the forward cutting position in FIG. 8A in the return stroke, the return stroke does not contribute to the cutting at all, In the configuration of FIG. 11A, the counting cannot be performed by moving the reciprocating plane tables 4a and 4b up and down, but in this configuration, the counting can be performed by moving the forward plane table 4a up and down.

In the case of the return cutting position shown in FIG. 8B in the return stroke, cutting is performed by the return plane blade 5b in the return stroke. In addition, since the cutting is performed in a state where the depressed surface α is generated, this configuration is a short work material feeding pattern incorporating the basic feeding pattern, and a moderate effect thereof can be obtained, and As described above, there is an advantage that the number of cuts can be counted.

Each of the above-described patterns corresponds to the central control unit CPU
Can be selectively specified by the input means to.
It is needless to say that a configuration in which only one of the above-described patterns (excluding the basic feed pattern) is executed is within the scope of the present invention.

In each of the above-described configurations, the return plane table 4b is disposed at the front position and the forward plane table 4a is disposed at the rear position. However, the return plane table 4b is disposed at the rear position, and the front plane table 4b is disposed at the front position. The outgoing plane table 4a may be arranged in this case, and even with this arrangement, the above-mentioned pattern does not change.

In the above-described configuration, the raising and lowering operation of the plane tables 4a and 4b is generated through the tilting of the tilting base 30,
The tilt base 30 may be divided into two front and rear parts, and the plane bases 4a and 4b may be independently lifted and lowered.

The above-described configuration is provided with the outgoing plane blade 5 having a different edge direction.
a and the re-plane blade 5b, but the same front plane blade 41a having the same cutting edge direction is provided on the plane table 40a,
The configuration shown in FIG. 13 in which the rear plane blade 41b is provided on the plane table 40b will be described. It should be noted that the specific configuration thereof can be applied to the above configuration as it is simply by replacing the plane table.
And its explanation is omitted. This plane table 41a
Is the front drive unit Zf, and the plane table 41b is the rear drive unit Zb.
The lifting / lowering operation control is performed. The drive control means can also be constituted by the central control unit CPU.

In the configuration shown in FIG. 13, both the blades of the plane blades 41a and 41b protrude rearward, and the workpiece is ground in the return stroke. Therefore, in the basic feed pattern, both the plane blades 41a and 41b retreat downward from the material feeding guide surface f in the forward stroke, and both project upward in the return stroke. Then, in the return stroke, the work material is double ground.

Similarly to this configuration, it is also proposed that the plane blades 41a and 41b both have forwardly protruding cutting edges (FIG. 15).
reference). In this case, the workpiece is ground in the outward stroke. Therefore, in the basic feeding pattern, both the plane blades 41a and 41b protrude upward from the material feeding guide surface f in the forward stroke, and both retreat downward in the return stroke.

Next, the special feeding pattern according to the present invention in the configuration of FIG. 13 will be described with reference to FIG.

That is, in the outward stroke, the plane blades 41a, 41
b are retracted downward, and during the return stroke, one plane blade 41
Only b (or plane blade 41a) protrudes upward from the material feeding guide surface f. As a result, as the work material reciprocates, cutting is performed only by the plane blade 41b (or plane blade 41a) in the return stroke, and the other plane blade 41a (or plane blade 41b) enters a standby state. Therefore, only the cutting edge of the plane blade 41b (or the plane blade 41a) contributes to the cutting and gradually wears. And this wear deteriorates the sharpness.

Therefore, in the return stroke of the final step, the plane blade 41a
And the plane blade 41b both project upward from the material feeding guide surface f,
For the first time, the plane blade 41a (or plane blade 41b) contributes to cutting. And this plane blade 41a (or plane blade 41)
The cutting edge of b) is sharper than the plane blade 41b (or plane blade 41a), and the final cutting can be performed with a good finish.

FIG. 15 shows the plane blades 41a and 41b both of which protrude forward.

In this case, in the forward stroke, one plane blade 4
Only the plane blade 1a (or the plane blade 41b) protrudes upward, and both the plane blades 41a and 41b are retracted downward in the return stroke, and the work material reciprocates in this state. Then, in the return stroke of the final step, both the plane blade 41a and the plane blade 41b project upward, and the plane blade 41b (or the plane blade 41a) contributes to the cutting for the first time.

In FIGS. 14 and 15 described above, in the final cutting step, only the unused plane blade may be protruded and the other plane may be retracted.

By the way, in the basic feed pattern described above and the special feed pattern shown in FIGS. 13 and 14, both the plane blades 41a and 41b are retracted downward during the non-cutting stroke. Accordingly, a wide depressed surface α is generated in the blade mounting groove 6 of the rotary table 3. For this reason, the support of the work material is lost at the site due to the depressed surface α, and when a short work material is applied, stable feeding cannot be secured. In this state, although cutting is not performed, unlike the case where only one retreats, the short work material tends to stray due to the wide depressed surface α and cannot be overlooked even in the non-cutting stroke. Also,
In the cutting process, even if a depressed surface α is generated due to the retreat of one of the plane blades 41a and 41b downward, the finished skin is deteriorated due to unstable running of the short work material.

Then, the short work material feeding pattern shown in FIG. 16 is selected, and the central control unit CPU (drive control means)
Is executed by

Here, FIG. 16A shows that both of the plane blades 41a and 41b are set to the both projecting positions projecting from the material feeding guide surface f in the forward stroke and the return stroke. As a result, the work material is cut in the return stroke, and neither the plane tables 40a and 40b are retracted downward in the forward stroke, so that a depressed surface α is not generated, and thus the short work material w can be stably fed. Becomes

FIG. 16B shows that one of the plane blades 41b (or plane blades 41a) and 41b is set to a cutting position in which the plane blade 41b (or plane blade 41a) and 41b protrude from the material feeding guide surface f in the forward stroke, and the plane blade in the return stroke Both of the positions 41a and 41b are located at both protruding positions protruding from the material feeding guide surface f. Thereby, the short workpiece w is cut in the return stroke, and only one of the plane tables 4a is retracted downward in the non-cutting forward stroke, so even if the depressed surface α is generated, it is not a large area. No big problem. Therefore, the feeding of the short workpiece w can be performed stably. In this pattern, even if the number of cuts is counted by raising and lowering the reciprocating plane tables 40a and 40b, counting can be performed by raising and lowering the forward plane table 4a.
In a configuration in which the blade edges of the plane blades 41a and 41b are projected rearward, in order to cause the same operation, both plane blades 41a and 41b are projected in the outward stroke and either of them is returned in the return stroke. Only one plane blade will be projected.

[0073]

As described above, according to the present invention, one plane blade is converted into a protruding position for each of the reciprocating strokes in which the workpiece is cut, and the other plane blade is moved during the reciprocating stroke. , While maintaining the retracted position, and at the final stroke or in the vicinity of it, the first protruding position adopts a feed pattern that cuts the work material, so the other plane blade edge preserves sharpness This contributes to the cutting only at the final stage, so that a good finished skin can be secured on the surface of the processed material.

In the case of employing the short work material feeding pattern, the influence of the occurrence of the depressed surface due to the retreat of the plane blade can be reduced as much as possible, and a stable material feeding becomes possible. Cutting may be performed. Further, in the tilt drive mechanism of the present invention for controlling the elevation of each plane blade, only one of the ground surfaces f is controlled by the drive control of the tilt motors M3 and M4.
The position can be quickly changed to the two positions where the projections are retracted and the other is retracted, the positions where both are retracted, or the positions where both are extended, and there is an excellent effect that each control described above can be performed easily and quickly. .
