2. Description of the Related Art The outline of a polishing apparatus will be described with reference to FIG. A rail (not shown) is provided on the frame 69, and the moving table 60 is attached so as to be slidable in the directions of arrows 92 and 93 along the rail. The movement of the moving table 60 is controlled by a table moving motor (not shown) rotating in the forward and reverse directions. A blade is placed and fixed on the moving table 60.

On the upper part of the moving table 60, the rough grindstone 11
K and finishing whetstone 12K are located. These rough whetstone 11
K and finishing whetstone 12K are whetstone rotation motors 11 and 12, respectively.
The tool is rotated by and the blade on the moving table 60 is polished. The grindstone rotating motor 11 and the rough grindstone 11K, and the grindstone rotating motor 12 and the finishing grindstone 12K are respectively moved up and down in the directions of arrows 90 and 91 by a grindstone lifting motor (not shown).

When polishing a blade, the rough grindstone 11K is first rotated, and then the grindstone rotation motor 11 and the rough grindstone 11 are rotated.
K is lowered in the direction of arrow 90 to bring the rough whetstone 11K into contact with the blade. In this case, the moving table 60 repeats reciprocating movements in the directions of arrows 92 and 93 by the forward and reverse rotations of the table moving motor. The reciprocating movement of the moving table 60 causes the blade to be polished over its entire length.

When polishing with the rough whetstone 11K is completed, the rough whetstone 11K is raised in the direction of arrow 91, and subsequently the whetstone rotation motor 12 and the finishing whetstone 12K are lowered in the direction of arrow 90. Then, similarly, the finishing table 12K is used for polishing while reciprocating the moving table 60. As described above, the blade is polished by the rough whetstone 11K and the finishing whetstone 12K.

As a conventional example for controlling the reciprocating movement of the moving table 60, there is a polishing apparatus disclosed in Japanese Patent Laid-Open No. 62-228358. This polishing apparatus is shown in FIG.
As shown in FIG. 2, the moving table 60 is fixed to the rack gear 100, and the rack gear 100 includes the pinion gear 1
05 meshes. The pinion gear 105 rotates forward and backward by driving the motor 106. The motor 1
06 is controlled by the control circuit 107.

The movable table 60 is provided with an operating rod 60T, and limit switches 101 and 102 are located at both ends of the movable table 60. The limit switches 101 and 102 are fixed to the frame 108. The limit switches 101 and 102 are located on the orbit of the reciprocating operating rod 60T and detect contact with the operating rod 60T.

For example, when the moving table 60 moves in the direction of arrow 92 from the state shown in FIG. 18, the operating rod 60T
Contacts the limit switch 102. Then, the limit switch 102 is turned on, and this ON signal is sent to the control circuit 1.
It is given to 07. In response to this, the control circuit 107 rotates the motor 106 in the reverse direction to move the moving table 60 in the direction of arrow 93.

Then, when the operating rod 60T contacts the limit switch 101, the control circuit 106 again moves the moving table 60 in the direction of arrow 92. In this way, the moving table 60 repeats reciprocating movements in the directions of arrows 92 and 93 based on the operation of the limit switches 101 and 102 by the operating rod 60T. 18, the grindstone rotation motors 11, 12, the rough whetstone 11K, the finishing whetstone 12K, etc. are omitted.

FIG. 19 shows another conventional polishing apparatus for reciprocating the moving table. This polishing apparatus is provided with a limit switch 64 close to the back surface of the moving table 60. The movement table 60 is changed by switching the limit switch 64.
The reciprocating movement of is controlled. A detector 63 is connected to the limit switch 64, and the detector 63 has V-shaped levers 63a and 63b as shown in the drawing. On the other hand, the moving table 60 has detection bars 61 and 62.
Is provided.

When the moving table 60 moves in the direction of arrow 92 from the state shown in FIG. 19, the kick portion 61F of the detection bar 61 eventually contacts the lever 63a of the detector 63, causing the V-shaped levers 63a and 63b to move in the direction of arrow 92. Push down in the direction.
The limit switch 64 is turned on by the switching of the levers 63a and 63b, a signal is given to the table moving motor through the switching circuit 65, and the moving table 60 moves in the reverse direction, that is, the direction of arrow 93.

Similarly, the kick portion 62F of the detection bar 62 is
When the lever 63b pushes down, the limit switch 64 is turned off, and the moving table 60 moves again in the direction of arrow 92. In this way, the kick portions 61F and 62F of the detection bars 61 and 62 are connected to the lever 63 of the detector 63.
The moving table 60 is pressed by pressing a and 63b.
Reciprocating movement is performed.

The position of the detection bars 61 and 62 can be adjusted. By adjusting the positions of the detection bars 61 and 62, the width of the reciprocating movement of the moving table 60, that is, the moving range can be adjusted. An enlarged view of the detection bar 61 is shown in FIG. An elongated slot 61G for adjustment is provided on the detection bar 61.
Is formed, and the positioning bolt 61N is fastened to the moving table 60 through the adjustment elongated hole 61G. The detection bar 62 has a similar structure.

When adjusting the movement range, the positioning bolt 61N is loosened. When the positioning bolt 61N is loosened, the detection bar 61 moves in the direction of the arrow 9 within the adjustment slot 61G.
It can slide freely in 2, 93 directions. Then, after the detection bar 61 is positioned at a desired position according to the size of the blade, the positioning bolt 61N is tightened to fix the position. The position of the detection bar 62 is adjusted in the same manner.

By thus adjusting the positions of the detection bars 61 and 62, the positions of the kick portions 61F and 62F on the moving table 60 are changed. Kick part 6
The lever 6 of the detector 63 can be adjusted by adjusting the positions of 1F and 62F.
The movement range can be adjusted by controlling the switching positions of 3a and 63b.

[0016]

The conventional polishing apparatus has the following problems. First, with the polishing apparatus shown in FIG. 18, the width of the reciprocating movement of the moving table 60 cannot be adjusted. The size of the blade to be polished varies,
For example, when polishing a relatively small blade, the width of the reciprocating movement of the moving table 60 may be small. FIG.
Since the width of this reciprocating movement cannot be adjusted with the polishing apparatus of No. 8, the moving table 60 reciprocates within an unnecessarily large range, and there is a problem that the work efficiency deteriorates due to useless movement.

Further, in this polishing apparatus, a blade is attached,
Removal and replacement work must be done within the range of movement. That is, for example, since the work of exchanging the blade is performed in the state as shown in FIG. 17, workability deteriorates due to the rough whetstone 11K, the finishing whetstone 12K, etc., which are close to the moving table 60, and there is a problem that the safety is also poor. is there.

The polishing apparatus shown in FIG. 19 has a detection bar 6
By adjusting the positions 1 and 62, the width of the reciprocating movement of the moving table 60 can be controlled. Therefore, the range of movement can be adjusted depending on the size of the blade, and there is no problem of performing unnecessary movement in an unnecessary range.

However, in this polishing apparatus, as described above,
When adjusting the movement range, first loosen the positioning bolts 61N and 62N of the detection bars 61 and 62 to remove the detection bar 6
After adjusting the positions of 1 and 62, the positioning bolt 61
It is necessary to tighten N and 62N. Therefore, it takes a lot of time to adjust the moving range, and there is a problem that work efficiency is reduced. Further, when adjusting the positions of the detection bars 61 and 62, it is necessary to stop the polishing work and temporarily stop the apparatus, which further lowers the work efficiency.

Therefore, an object of the present invention is to provide a polishing apparatus capable of easily adjusting a moving range and having excellent workability and safety.

【Example】

[First Embodiment] A first embodiment of the polishing apparatus according to the present invention will be described with reference to the drawings. The outline of the apparatus is shown in FIG.
A movable table 2 which is movable in the directions of arrows 92 and 93 is attached to the frame 4. The movable table 2 is provided with a blade mount 6, and the blade 10 which is an object to be polished is mounted and fixed to the blade mount 6. A reference end mark 6M indicating a reference end position is formed on the blade mount 6. Then, one end of the blade 10 is positioned and attached to the reference end mark 6M.

In this way, the blade 10 is attached to the blade mount 6
When attached to the
It is only necessary to position it at M, and the work of attaching the blade 10 is easy. That is, for example, if the center of the blade 10 is to be positioned and attached to the center of the blade mounting base 6, it is necessary to measure the entire length of the blade 10 and determine the center portion thereof, which is troublesome in the mounting work.

The moving table 2 is adapted to move along a rail (not shown) on the frame 4. As shown in the drawing, a rack gear 7 is provided on the bottom surface of the moving table 2, and a pinion gear 24 fixed to the shaft of the feed motor 22 is meshed with the rack gear 7. That is, the moving table 2 moves in the directions of arrows 92 and 93 according to the rotation of the feed motor 22. The feed motor 22 rotates in the opposite direction when a reverse rotation signal is given.

On the upper part of the moving table 2, grindstones 31, 32 are provided.
Is located, and grindstone rotation motors 11 and 12 are provided in the grindstone bases 31 and 32. Then, the grindstone rotating motors 11 and 12 are respectively provided with rough grindstones 11 which are polishing parts.
K and a finishing grindstone 12K are connected, and the grindstone rotating motors 11 and 12 rotate to grind the blade 10.

Further, the grindstone bases 31 and 32 are lift motors 3.
By 3, 34, it can be moved up and down in the directions of arrows 90, 91. The rotating shafts of the elevating motors 33 and 34 are formed as elevating screws 33J and 34J, and these elevating screws 33J and 34J are screwed into nuts 31W and 32W integrally fixed to the grindstone bases 31 and 32, respectively. Lifting screw 33J,
By screwing 34J and the nuts 31W and 32W, the whetstone bases 31 and 32 are controlled to move up and down in accordance with the drive of the lifting motors 33 and 34.

A detection bar 20 is provided on the bottom of the moving table 2.
Are fixed and move integrally with the moving table 2. On the other hand, the frame 4 is provided with a reference end position detection switch 8 which is a reference end position detector, and detects the detection bar 20.

As shown in FIG. 1, the reference end portion position detection switch 8 is provided at a position where it is detected that the reference end mark 6M and the rough grindstone 11K have reached a position substantially opposite to each other. . Then, when the detection bar 20 is detected, the reference end position detection switch 8 outputs a reference end position detection signal.

As will be described later, when the reference end position detection signal is output, the moving table 2 is moved in the direction of arrow 92. That is, as shown in FIG. 1, the moving table 2 moving in the direction of the arrow 93 reverses at a position where the end of the blade 10 slightly passes the position of the rough grindstone 11K and moves in the direction of the arrow 92. Become. Rough whetstone 1
Since it is reversed after passing the 1K position, the blade 10 can be sufficiently polished to the end.

The reference end position detection switch 8 detects the end of the blade 10 positioned and attached to the reference end mark 6M and outputs a reverse rotation signal. Deterioration of the switch mechanism can be prevented as compared with a configuration in which the central portion is detected and a reverse rotation signal is output.

That is, when an attempt is made to output a reverse rotation signal by measuring the amount of movement in both directions with reference to the center of the moving table 2 and the blade 10, the switch is turned on twice during one reciprocating movement of the moving table 2. Therefore, the deterioration of the switch mechanism becomes severe. On the other hand, in the present embodiment, since the ends of the movable table 2 and the blade 10 are detected, only one ON operation is required for each reciprocation, and deterioration of the switch mechanism can be prevented.

The frame 4 is also provided with an initial position detection switch 5 which is an initial position detector, and the detection bar 20
An initial position detection signal is output at the time of detecting. The initial position detection switch 5 is provided at a position for detecting an end portion (replacement initial position) of the moving table 2 that reciprocates.
The reference end position detection switch 8 and the initial position detection switch 5 are limit switches.

FIG. 2 shows the operation panel 4H of the polishing apparatus shown in FIG. Turn on the automatic operation button 36 as the operation start input section
When it is N, the LED 40 is turned on and the moving table 2 is indicated by the arrow 9
Starts reciprocating movement in the 2,93 direction. The adjustment dial 35 as a movement range setting unit is for adjusting the width of the reciprocating movement of the movement table 2, that is, the movement range. As buttons for controlling the rough whetstone, an up button 31a and a down button 3
1b and a rotary button 31c are provided. Further, as buttons for controlling the finishing grindstone, the up button 32a and the down button 32 are similarly provided.
b, a rotary button 32c is provided. When the cycle stop button 37 as the operation stop input section is turned on, the moving table 2 moves to the end of the rail (not shown) and stops, and the blade 10 is replaced.

The specific procedure for polishing the blade 10 is as follows. First, one end of the blade 10 is positioned, attached and fixed to the reference end mark 6M formed on the blade mounting base 6 of the moving table 2. Then, the automatic operation button 36 of the operation panel 4H is turned on to start moving the moving table 2. After that, the moving table 2 repeats reciprocating movements in the directions of arrows 92 and 93 within a predetermined moving range.

After the movement of the moving table 2 is started, polishing with the rough grindstone 11K is first performed. In this case, operation panel 4
The H rotation button 31c is pressed to rotate the rough whetstone 11K. Then, the down button 31b is pressed to lower the whetstone base 31 in the direction of arrow 90. And the blade 10 and the rough whetstone 11
When it comes into contact with K, the depression of the descending button 31b is released to stop the descending of the grindstone base 31. The moving table 2 reciprocates within a predetermined moving range, and polishing is performed in this state.

When the polishing with the rough whetstone 11K is completed, the raising button 31a is pushed to raise the whetstone base 31 in the direction of arrow 90. Then, the rotary button 31c is pressed again to press the rough whetstone 11
Stop rotation of K. Then, polishing with a finishing grindstone 12K is performed. When polishing of the finishing grindstone 12K is completed, the lift button 32a is pressed to raise the grindstone base 32, and the rotary button 32 is pressed again.
Press c to stop the rotation of the finishing grindstone 12K.

After finishing the polishing as described above, the cycle stop button 37 is pressed. According to the input of the cycle stop button 37, the moving table 2 is railed (not shown).
Return to the end of and stop. In the present embodiment, the width of the predetermined moving range in which the moving table 2 repeats reciprocating movement is
Adjustment is performed by rotating the adjustment dial 35 on the operation panel 4H.

FIG. 3 shows a hardware configuration diagram of the polishing apparatus in this embodiment. CPU5 on the bus line 50
1, ROM52, RAM53 are connected, CPU
Reference numeral 51 controls each unit according to a program stored in the ROM 52. Adjustment dial 35 shown in FIG.
Are connected to the bus line 50 via the A / D converter 54. In addition, an automatic operation button 36, a cycle stop button 37
Is also connected to the bus line 50 via the A / D converter 54. Although various buttons other than the adjustment dial 35, the automatic operation button 36, and the cycle stop button 37 provided on the operation panel 4H are also connected to the A / D converter 54, they are omitted in FIG. .

The reference end position detection switch 8 is connected to the CPU 51 through the input port 55. The reference end position detection signal output from the reference end position detection switch 8 is given to the CPU 51, and the CPU 51 causes the moving table 2 to move.
Is located at the detection position as shown in FIG. Further, the CPU 51 controls the rotations of the lifting motors 33 and 34, the grindstone rotating motors 11 and 12, and the feed motor 22 through the output port 56. The control of these motors is performed according to ON / OFF operation of each button of the operation panel 4H. Further, a clock 58 as a movement amount counting unit is connected to the CPU 51, and the clock 58 outputs a clock signal.

FIG. 4, FIG. 5 and FIG. 6 show flow charts of the movement range control in this embodiment. Hereinafter, the specific processing content executed by the CPU 51 will be described with reference to this flowchart. Automatic operation button 36 on operation panel 4H
When (FIG. 2) is turned on, the CPU 51 causes the A / D converter 5
We recognize this through 4 (Fig. 3). Here, when the automatic operation button 36 is turned on, the moving table 2 is at the initial position as shown in FIG.

When the CPU 51 recognizes that the automatic operation button 36 is ON, it starts the rotation of the feed motor 22 to start moving the moving table 2 in the first direction (FIG. 4, step S2). In this case, the first direction is the direction indicated by the arrow 93 in FIG. 7. That is, the moving table 2 is moved in the direction in which the reference end mark 6M and the rough whetstone 11K face each other.

Then, the CPU 51 starts the protection timer (step S4). The limit movement time Y is stored in the ROM 52, and it is determined whether or not Y seconds have elapsed (step S6). For example, it is assumed that the limit movement time Y is set to 15 seconds. This limit travel time 15
The second is a set value for stopping the moving table 2 when the reference end position detection switch 8 or the like is abnormal and the reference end position cannot be detected. Therefore, a value larger than the time required for the moving table 2 to reach the reference end position is set as the limit moving time Y.

If the reference end position detection switch 8 has an abnormality such as a failure, the reference end position signal is not given in step S10, and therefore, when the protection timer has passed 15 seconds, the first movement of the movement table 2 is stopped. The movement in one direction (arrow 93) is stopped (step S8). Then, in this case, an error is displayed, the operator is notified of the occurrence of the abnormality, and the processing ends.

When the reference end position detection switch 8 is operating normally, the reference end position detection signal is given when the detection bar 20 reaches the reference end position detection switch 8. That is, if the moving table 2 is located in the state shown in FIG. 1, the CPU 51 recognizes this via the input port 55 (step S10) and stops moving the moving table 2 in the first direction (arrow 93). (FIG. 5, step S12). Then, a reverse rotation signal is given to the feed motor 22 to move the moving table 2 in the second direction (direction of arrow 93) (step S14).

While the moving table 2 is moved in the second direction (direction of arrow 93), the CPU 51 takes in the voltage value indicated by the adjustment dial 35 (step S16). Then, the timer value X indicating the amount of moving time is obtained from this voltage value (step S18). The timer value X is calculated according to a preset arithmetic expression. The adjustment dial 35 is adjusted by the operator according to the length of the blade 10.

An example of an arithmetic expression for obtaining the timer value X is shown in "Equation 1" below. The variable range of the voltage value by the adjustment dial 35 is 0V to 5V, and the adjustment range of the movement width is 200 mm to 500 mm. The moving table 2 is supposed to move at a speed of 100 mm per second. In addition, 0V to 5V which is changed by the adjustment dial 35 is 0 to
It is assumed that the digital value a of 255 is output to the CPU 51. Also, the timer interrupt (see Fig. 5) described later is 100m.
It is assumed to be executed at intervals of sec.

[0060]

[Equation 1]

Based on the above arithmetic expression, the timer value X
After that, the timer interrupt process is started (step S2).
0). That is, when the detection bar 20 contacts the reference end position detection switch 8 and the reference end position detection signal is output, the timer interrupt process starts. With a timer interrupt,
According to the clock signal output from the clock 58,
"1" is subtracted from the timer value X and stored as a new timer value X (step S50).

Then, the CPU 51 sets the timer value X to "0".
It is determined whether or not (step S22), and when it becomes "0", the timer interrupt is stopped through step S24 (FIG. 6, step S26). Further, the CPU 51 gives a command to the feed motor 22 through the output port 56 to stop the movement of the moving table 2 in the second direction (arrow 92) (step S28), and subsequently gives a reverse rotation signal to give the feed motor 22. Is reversely rotated to move the moving table 2 in the first direction (arrow 93) (step S30). That is, the reverse signal is output when the amount of change in the clock signal from the time when the reference end position detection signal is received and the timer value X become equal.

After this, the process proceeds to step S32 of FIG. 5, and it is determined whether or not the reference end position signal is received. Then, when the moving table 2 moving in the first direction (arrow 93) reaches the reference end position as shown in FIG. 1 again, it receives the reference end position signal and stops the movement of the moving table 2. It is moved in the second direction (arrow 92) (steps S12 and S).
14).

As described above, the moving table 2 is moved to the arrow 9
The width of the moving range for reciprocating in the 2,93 direction is regulated according to the timer value X. Then, this timer value X is determined based on the voltage value indicated by the adjustment dial 35. That is, by rotating the adjustment dial 35 and changing the timer value X, the moving table 2
It becomes possible to easily control the range of movement in which the robot reciprocates.

In this way, the movable table 2 reciprocates to polish the blade 10. When stopping the polishing work,
The operator presses the cycle stop button 37 (FIG. 2).
When the cycle stop button 37 is pressed, the CPU 51 recognizes this and proceeds from step S24 to step S34 to determine whether or not the initial position signal has been received.

As described above, the initial position signal is output when the initial position detection switch 5 detects the initial position of the moving table 2. FIG. 7 shows a state in which the moving table 2 has reached the initial position. In the state of FIG. 7, an initial position signal is output from the initial position detection switch 5, and the CPU 51 fetches this initial position signal via the input port 55 and stops the movement of the movement table 2 (step S36).

The determination as to whether or not the cycle stop command is given (step S24) is performed by setting the timer value X to "0" while the moving table 2 is moving in the second direction (arrow 92) as described above. It will be done after.

Therefore, for example, when the cycle stop button 37 (FIG. 2) is pressed while the moving table 2 is moving in the direction away from the initial position, that is, the first direction (arrow 93), the moving table 2 2 moves once to the reference end position (steps S32 and S12). Then, after the moving direction is switched to the second direction (arrow 92) (step S14), it stops at the initial position. Further, while the moving table 2 is moving in the direction approaching the initial position, that is, in the second direction (arrow 92), the cycle stop button 37
When (FIG. 2) is pressed, the moving table 2 moves to the initial position as it is and stops.

When the cycle stop button 37 is pressed, the moving table 2 stops at the initial position as shown in FIG. 7, so that the rough whetstone 11K and the finish whetstone 12K do not become an obstacle during the work of removing and mounting the blade 10. Therefore, the workability is good and the safety can be secured.

[Second Embodiment] Next, FIG. 8 shows a hardware configuration diagram of a polishing apparatus according to a second embodiment of the present invention. In this embodiment, a timer circuit 57 is connected to the bus line 50, and a clock signal from a clock 58 is given to the timer circuit 57. CPU5

Details of the timer circuit 57 are shown in FIG. C
The timer value X from the PU 51 is captured and stored in the timer value storage circuit 71. At this point, the counter 73 is reset and starts counting according to the clock signal from the clock 58. Then, the comparison circuit 72 compares the timer value X stored in the timer value storage circuit 71 with the value of the counter 73, and when both match, the CPU 51
And outputs a coincidence signal toward.

The CPU 51 outputs a reverse rotation signal based on this coincidence signal, and reversely moves the moving table 2 moving in the second direction (arrow 92) in the first direction (arrow 93). According to this embodiment, the CPU 51 does not need to perform the timer interrupt processing shown in FIG. 5, and the processing content is simplified.

Set to 400 mm. In the ROM 52 (FIG. 3), the timer value X corresponding to each moving range 200 mm, 300 mm, 400 mm is set and stored in advance, and the reciprocating movement of the moving table 2 is controlled according to the selected moving range. The other mechanism and operation are similar to those of the first embodiment.

The movement range stored in 2 (FIG. 3) is read and increased or decreased. Then, this moving range is set to the LED drive circuit 118.
LED is displayed on the display unit 117 via. This display 1
17 is also provided on the operation panel 4H.

The CPU 51 calculates the timer value X according to the movement range input by operating the increase button 115 and the decrease button 116, and controls the reciprocating movement of the movement table 2. Further, instead of executing the calculation, the timer value X corresponding to the input movement range may be read out based on the conversion table stored in the ROM 52 in advance, and the reciprocating movement of the movement table 2 may be controlled accordingly. it can. The other mechanism and operation are similar to those of the first embodiment.

[Fifth Embodiment] Next, a fifth embodiment of the polishing apparatus according to the present invention will be described. In the first embodiment,
Moving table 2 based on the timer value X indicating the amount of moving time
Controlled the range of movement for reciprocal movement. In contrast,
In the present embodiment, the movement range is controlled based on the rotation speed Z, which is the drive speed of the feed motor 22.

The operator sets the desired movement range to the adjustment dial 35 shown in the first embodiment, the setting buttons 110, 111 and 112 shown in the third embodiment, or the increase button shown in the fourth embodiment. 115, enter through the decrease button 116,

On the other hand, the rotation speed of the feed motor 22 is detected as the detected rotation speed, and the CPU 51 controls the feed motor 22 at the time when the detected pulse number from the time when the moving table 2 reaches the reference end position becomes equal to the rotation speed Z. And outputs a reverse rotation signal. In this way, the movement range is controlled according to the rotation speed Z.

The flowcharts of the processes in this embodiment are shown in FIGS. 13, 14 and 15 below. The basic processing contents are the same as in the first embodiment, but in step S19 of FIG. 14, the voltage value indicated by the adjustment dial 35 is replaced with the rotation speed Z. An example of an arithmetic expression for obtaining the rotation speed Z is shown in "Equation 2" below. The variable range of the voltage value by the adjustment dial 35 is 0V to 5V, and the adjustment range of the movement width is 200 mm to 500 mm. The rotation when the moving table 2 moves 100 mm is 100. 0V to 5V that can be changed by the adjustment dial 35
Is output to the CPU 51 as a digital value a of 0 to 255.

[0081]

[Equation 2]

After the rotation speed Z is obtained in this way, the counting of the detected rotation speed Z'is started (step S21).
The detected rotation speed Z ′ of the feed motor 22 is detected by a mechanism as shown in FIG. 12, for example. FIG. 12A shows the feed motor 2

The rotation detector 23 includes a light emitting element and a light receiving element, and is provided so that the light emitting element and the light receiving element are positioned with the slit plate 22M interposed therebetween.
That is, the rotation speed of the feed motor 22 can be detected by the number of times the rotating slit plate 22M is shielded.

The detection signal from the rotation detector 23 is taken into the CPU 51 via the input / output conversion circuit 25. In addition,
Instead of the light emitting element and the light receiving element, a limit switch may be provided to count the contact with the protrusion of the slit plate 22M. Further, it is also possible to count the detected rotation speed Z ′ by the magnet and the magnetic sensor.

After the count of the detected rotation speed Z'is started in step S21, it is determined whether or not the rotation speed Z and the detected rotation speed Z'have become equal, and the detected rotation speed Z'reaches the rotation speed Z. At this point, the movement of the moving table 2 in the second direction (arrow 92) is stopped (step S28), and the CPU 51 outputs a reverse rotation signal to move the moving table 2 in the first direction (arrow 93) (step S30). .

As described above, the width of the reciprocating movement of the moving table 2 is controlled based on the rotation speed Z. 13 and 1

The state (state shown in FIG. 16) of reaching the center position of the whetstone 11K and the finishing whetstone 12K is detected. Then, the amount of movement of the moving table 2 from this state is measured, and a reverse rotation signal is issued.

Since the moving amount is measured with the center of the moving table 2 and the blade 10 as a reference, a reverse rotation signal is issued at the time when the moving table 2 has moved by about half the desired moving range, and the moving table 2 is moved in the opposite direction. Let In this embodiment, the blade 10

[0093]

In the polishing apparatus according to the first aspect of the present invention, one end of the object to be polished is attached to the moving table while being positioned at the reference end position. Then, a predetermined movement range according to the length of the polishing object is input to the movement range setting unit, and the movement range set value is set based on this movement range. In addition, the reference end position detector detects that the polishing unit and the reference end position of the moving table have reached positions facing each other, outputs a reference end position detection signal, and the movement amount counting unit, It is activated by the reference end position detection signal to count the amount of movement of the moving table or the polishing section.

Then, the control unit compares the moving range setting value set in the moving range setting unit with the count value of the moving amount counting unit, and when both values match, a reverse rotation signal is sent to the driving unit. Is output. Further, the control unit outputs a reverse rotation signal toward the drive unit when the reference end position detection signal is output.

As described above, one end of the object to be polished is positioned and attached to the reference end position, a reverse rotation signal is output based on the reference end position, and the moving table or the polishing unit moves in the opposite direction. That is, it is only necessary to position one end of the object to be polished with respect to the reference end position that serves as a reference for the movement of the moving table and the polishing unit in the opposite direction. Therefore, the work of attaching the object to be polished can be easily performed, and the moving table or the polishing section can be reliably moved in the opposite direction at the end of the object to be polished.

Further, a reverse rotation signal is output according to the movement range set value set in the movement range setting section, and the movement table or the polishing section moves in the opposite direction. Therefore, the moving range can be freely controlled by inputting the moving range according to the length of the object to be polished through the moving range setting unit. Therefore, the movement range can be adjusted easily and accurately.

In the polishing apparatus according to the second aspect, the operation start command input through the operation start input unit is given to the drive unit, and when the drive unit receives this operation start command, the drive unit moves between the polishing unit and the moving table. The moving table or the polishing section is moved in a direction in which the reference end position faces each other.

By simply inputting the operation start command in this way, the moving table or the polishing section moves in the directions in which the polishing section and the reference end position of the moving table face each other, and reaches the reference end position. After that, reciprocating movement is performed within a predetermined movement range as described above. Therefore, it does not take much time to start the polishing operation, and the work efficiency can be improved.

In the polishing apparatus according to the third aspect, the limit moving range set value is stored in the controller. And
The control unit outputs a stop signal when the movement amount of the movement table or the polishing unit from the time when the operation start command is given to the drive unit and the limit movement range set value become equal. The drive unit receives the stop signal and stops the movement of the moving table or the polishing unit.

After the operation start command is given in this way,
The movement of the moving table or the polishing unit is stopped when the moving amount of the moving table or the polishing unit reaches the limit moving range set value. Therefore, for example, even when the reference end position detector has an abnormality and the reference end position detection signal is not output, the movement of the moving table or the polishing unit is limited to the preset limit movement range set value. It will be stopped when it reaches. Therefore, even if an abnormality occurs, it is possible to avoid overloading the drive unit.

In the polishing apparatus according to the fourth aspect, the initial position detector detects that the moving table or the polishing section is located at the replacement initial position of the object to be polished, and sends the initial position detection signal to the drive section. To output. Then, the operation stop command input through the operation stop input unit is given to the drive unit.

When the moving table or the polishing section is moving in a direction away from the replacement initial position when the operation stop command is given, the driving section moves after the moving table or the polishing section is switched in the opposite direction. Move the table or polishing unit to the replacement initial position. When the moving table or the polishing section is moving in the direction approaching the replacement initial position, the moving table or polishing section is moved to the replacement initial position as it is. Then, the drive unit stops the movement of the moving table or the polishing unit when the initial position detection signal is given.

Thus, only by inputting the operation stop command, the moving table or the polishing section stops at the replacement initial position. Therefore, it is possible to stop the movement of the moving table or the polishing section and to increase the work efficiency without exchanging the object to be polished, and further it is excellent in safety.
