To automatically perform reciprocating cutting of the material based on material detection by a detector by alternately rotating the material feeding member that presses the material against the table in forward and reverse directions.

A controller is linked to the reciprocating mechanism of the fishing force, thereby changing only the rotation of the material feeding member while one of the blades is held at the cutting position, and cutting the material one way in reciprocating material is performed an arbitrary number of times. After that, the reciprocating mechanism of the fishing force is operated, the blade is switched to cut even the burrs of the material, and the operation of finishing the material after rough cutting a plurality of times is also automatically performed.

It is in. Next, an embodiment of a reciprocating cutting type superfinished copper board for woodworking according to the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 indicates a table for a superfinished copper board for woodworking, and a concave portion 2, preferably diagonal, is provided in the center of the table.

Reference numeral 3 denotes a sliding copper plate which is slidably fitted into the concave part 2, and is formed to have a length more than twice the length of the concave part, and on one side and the other side thereof, forward and backward facing blades 4, 4' are installed side by side.

A is a sliding copper plate 3 in order to use the double blade 4゜4' interchangeably.
It is a reciprocating mechanism that reciprocates in the left and right directions, and a rack 5 is attached to the plane board 3, and a pinion 7 driven by a motor 6 with a brake is engaged with the rack 5, or a structure shown in the drawings is used. Although not shown, there is a structure in which the piston rod of a cylinder fixed on a table is connected to a sliding copper plate, and a structure in which both ends of a wire wound around a drum driven by a reducer motor with a brake are connected to a sliding copper plate. A structure is adopted in which a screw motor is screwed onto a screw shaft suspended horizontally at the bottom of the sliding copper plate. When using a motor, the direction of rotation is changed by switching the power supply to alternately move the sliding copper plate in the opposite direction. move it.

Reference numeral 8 denotes a material feeding member disposed oppositely on the table 1, which is stretched around a pair of rollers 9 and 10, and by changing the rotational direction of the roller 10, the material feeding direction is alternately changed.

A pressing member 11 is engaged with the back surface of the material feeding member 8 in correspondence with the sliding copper disc 3, which presses the workpiece 12 against the sliding copper disc 3 to prevent the blade from escaping during cutting.

Reference numeral 13 denotes a rotation mechanism that drives the material feeding member 8, and the rotating direction is changed by switching the power supply to rotate the material feeding member 8 in the forward or reverse direction.

PH1 and PH2 are phototube type (limit switch or proximity switch type are also available) detectors that detect the ends of the workpiece 12 at the front and rear sides of the cutters 4, 4'.
A light emitting section and a light receiving section are disposed opposite to each other with the light emitting section sandwiched therebetween, and a detection signal is emitted when the end of the workpiece 12 is removed from the light projection path.

MSIF and MSIR are electromagnetic switches that change the operation of the copper plate reciprocating mechanism A, with MSIF being for forward movement and MMSIR being for backward movement.

MS2F and MS2R are electromagnetic switches that switch the operation of the material feeding member rotation mechanism 13; MS2F is for forward rotation, and MS2R is for forward rotation.
is for reversal.

LSI and LS2 are limit switches for detecting the position change of the sliding copper plate 3.
detects completion of return movement.

T1゜T2 is a timer that sets the stop time of the material feeding member rotation mechanism A, T1 gives a time difference for switching from normal rotation to reverse rotation, and T2 gives a time difference for switching from reverse rotation to normal rotation, so that the rated current is reasonable. This is so that rotation switching is performed.

C is a controller for temporarily stopping the operation of the copper plate reciprocating mechanism A, which uses a known electric type (including electromagnetic, electronic type, etc. that use electricity) counter until the set count is reached. , the switching operation of the copper disc reciprocating mechanism A is stopped, one of the blades is held at the cutting position, and only the switching operation of the rotation mechanism 13 of the material feeding member 8 is performed to perform one-way cutting of the workpiece 12. This controller C uses a foot-operated or manual switch instead of the above-mentioned counter, stops the switching operation of the copper plate reciprocating mechanism A by the second switch, and holds one of the blades in the cutting position. , one-way cutting of the workpiece 12 is performed, and when the desired finished surface is obtained, the copper plate reciprocating mechanism A is switched by a switch, and the other blade is positioned at the cutting position. Or, for example, using a surface defect detection device such as Model 5DD-Zoo or Model 5DB-1400 manufactured by Takenaka Electronics Co., Ltd.
When there is a defect on the surface of the workpiece 12 using this device, the switching operation of the copper disk reciprocating mechanism A is stopped, one blade is held in the cutting position, and the workpiece 12 is cut one way an arbitrary number of times. , When defects on the finished surface of the workpiece 12 are eliminated, this is detected and the reciprocating mechanism A is switched to position the other blade at the cutting position.

PBl is a push button switch, turning it on starts the machine and turning it off stops it.

Figure 5 shows a case where only one detector PH is provided on the front side of the cutlery, and the detection signal of the detector PH is sent to the timer T.
The timer T measures the length of the workpiece 12, this measured value is stored in the storage device M, and switching control between the reciprocating mechanism A of the copper plate and the rotation mechanism 13 of the material feeding member 8 is performed. If so, two detectors PH1 and PH2 can be installed at the front and rear of the cutlery.
The same effect as in the case where a is provided is achieved.

Since one embodiment of the reciprocating cutting type super-precision copper plate for woodworking according to the present invention is configured as described above, when the all-electric counter is used as the controller C of the copper plate reciprocating mechanism A, the controller C When the count number is set to 1 and the push button switch FBI is turned on, the electromagnetic switch MSIF is activated; reciprocating mechanism A
The copper plate 3 is positioned so that the forward-facing blade 4 is in the cutting position, and accordingly, the limit switch LSI is operated, the electromagnetic switch MS2F is activated, and the rotation mechanism 13 rotates the material feeding member 8 in the forward direction. Therefore, if the workpiece 12 is fed onto the table 1 at this time, the workpiece 12 will be transferred backward on the table 1 and its lower surface will be roughly cut by the forward-facing blade 4. When the rear end comes off the detector PT (1), the detector PH1 detects the completion of cutting, activates the electromagnetic switch MSIR and the timer T1, and the reciprocating mechanism A moves the copper disc 3 to the rearward-facing blade 4 in the cutting position. At this time, the rotating mechanism 13 whose reversal timing has been delayed by the timer T1 rotates in the reverse direction and rotates the material feeding member 8 forward.
is transported forward on the table 1, its lower surface is finished by a backward-facing cutter 4', and when the machining is finished, it is sent out to the front of the table 1.

However, depending on the workpiece material, only one rough cutting may leave scratches or unevenness on the machined surface, and rough cutting may have to be performed multiple times.In this case, set the count number to 2 in controller C. Then, when the push button switch PB1 is turned on, the electromagnetic switch MSIF is activated, and the reciprocating mechanism A positions the copper plate 3 so that the forward-facing blade 4 is in the cutting position, and accordingly, the limit switch LSI is operated. , the workpiece 12 is fed onto the table 1 at this time by the force that causes the rotation mechanism 13 to rotate the material feeding member 8 in the forward direction by activating the electromagnetic switch MS2F, the workpiece 12 moves backward on the table 1. After being transferred, the lower surface is roughly cut by the forward-facing cutter 4, and when it comes off the rear edge detector PH1 of the workpiece 12, the detector PH1 detects the completion of cutting,
A detection signal is generated, but in this case, the electromagnetic switch MSIR is not activated by the action of the controller C, and only the timer T1 is activated, and when the set time has elapsed, the electromagnetic switch MS2R is activated and the rotation mechanism 13 is reversed. As the material is rotated, the material feeding member 8 rotates forward, slides on the stationary blade 4 facing forward, and is returned to the front of the table 1. At this time, the detector PH2 detects the position of the workpiece 12. The rear end is detected, a detection signal is sent to the timer T2 to activate it, and after the set time has elapsed, the electromagnetic switch MS2F is activated and the rotation mechanism 13 is rotated in the forward direction. The lower surface of the workpiece is roughly cut again, and when the rough cutting is nearing the end, the detector PH1 detects the workpiece 12.
detects the terminal and issues a detection signal, but in this case, the controller C does not operate, so the detection signal is sent to the timer T2 and the electromagnetic switch MSIR, and the reciprocating mechanism A is moved by the operation of the electromagnetic switch MSIR. Then, position the steel equipment 3 so that the backward-facing blade 4' comes to the cutting position, and accordingly,
The limit switch LS2 is activated, and as the set time of the timer T1 has elapsed, the electromagnetic switch MS2R is activated,
Since the rotation mechanism 13 is reversed and the material feeding member 8 is rotated forward, the workpiece 12 is transferred forward on the table 1, its lower surface is finished cut, and when the processing is finished, it is moved to the front of the table 1. In this case, the workpiece 12 is subjected to two consecutive rough cuttings and then finish cutting.

Furthermore, with this steel, even after two rough cuttings, scratches and unevenness remain on the machined surface, and if the scratches and unevenness cannot be removed until rough cutting is performed three times or more, set the count of controller C to 3 or more. Then, after rough cutting three or more times, finish cutting is performed.

In addition, since the state of scratches and unevenness on the workpiece 12 differs for each workpiece, when rough cutting is performed, the number of times is determined mechanically using the counter type controller C as described above. In order to prevent this, the above-mentioned manual or foot-operated switch is used as the controller C, and the operator can control the workpiece without any scratches or irregularities. Check the scraped skin and operate only if further scraping is necessary, or
If the surface defect detection device is used to inspect the cut surface and rough cutting is repeated only when re-cutting is required, unnecessary machining of the workpiece 12 can be avoided.

As described above, the reciprocating cutting type super-finishing planer for woodworking according to the present invention rotates the material feeding member backward when the forward-facing blade is in the cutting position, and performs forward cutting of the workpiece material. and
When forward cutting is completed, the end of the workpiece is detected by a detector, and based on this detection signal, the reciprocating mechanism of the steel gear and the rotation mechanism of the material feeding member are commanded to reverse operation, and the blade is turned backward. This is because it moves the material to the cutting position and rotates the material feeding member forward to perform back-cutting of the workpiece.
Since so-called reciprocating cutting of workpiece materials can be performed automatically and continuously in both the reciprocating process and the night shift process, it is possible to greatly save labor and increase efficiency in superfinishing work such as plates or square materials. Not only can the workpiece be supplied and taken out in the same place, it is easy to work, does not take up much space, and does not require accessories such as a pre-picking device for the workpiece. It is economical to do so.

In particular, this reciprocating cutting type super-finishing planer for woodworking has the near blades placed side by side in opposite directions, and the secondary blades are alternately used, so you can change the direction of one blade to perform reciprocating work. Unlike when cutting, if the blade has good edge retention and one of the near blades is adjusted for rough cutting and the other for finishing, it is possible to perform rough cutting and finishing on the workpiece material continuously. In addition, by finely adjusting the back edge of one blade and the other, you can suppress the back-eye phenomenon that occurs when one-way feed is used in reciprocating cutting, and the back-edge phenomenon that occurs when cutting in one direction can be suppressed. It is possible to obtain a good finished surface that does not occur.

In addition, this super-finished steel shell is associated with a controller that stops the reciprocating mechanism of the steel equipment and temporarily cuts the material in one direction without changing the blade. Therefore, if the workpiece has scratches or unevenness on the machined surface after one rough cutting, the above controller will stop only the operation of the reciprocating mechanism.
If one of the blades is held in the cutting position and only the rotating mechanism changes the rotation of the material feeding member, the material is moved back and forth and rough cutting is repeated in one direction, and after the scratches and irregularities are removed, the reciprocating mechanism is switched. It is also possible to perform continuous automatic operations such as performing finishing cutting, performing finishing cutting several times, and completing the machining by finishing once.
