Detailed Description of the Invention The present invention relates to a super-finished copper board for woodworking that is capable of reciprocating cutting and one-way cutting of wide materials. A sliding copper plate is attached to the stand by means of an attachment means, and moved from side to side by a reciprocating mechanism, and attached in opposite directions.
To intentionally perform reciprocating cutting of a material by alternately positioning the fishing force of the knife for cutting and alternately rotating a material feeding member corresponding to a table in forward and reverse directions.

A stationary copper disc is attached to a reciprocating table provided at the bottom of the concave part of the table by means of an attachment means, and is stopped at the cutting position by means of a fixing means, and the material feeding member is rotated in forward and reverse directions, and the width is To be able to cut a wide range of materials.

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

In the figure, 1 is a table for a superfinished copper board for woodworking, and a diagonal recess 2 is preferably provided in the center of the table.

Reference numerals 3 and 4 denote a sliding copper plate for sliding the concave part 2, and a stationary copper plate for keeping the concave part 2 at a cutting position, which are attached to a mounting means 6 such as a pin of the carriage 5 fitted to the bottom of the concave part 2. By removing the hook, it can be easily replaced and used, and the sliding copper plate 3 has two fishing rods 7 and 7', one facing forward and the other facing backward, installed side by side, and the stationary copper plate 4 has two fishing rods 7 and 7' attached to the width of the table. Attach one fishing force 8 of similar length.

A is a reciprocating mechanism that reciprocates the sliding copper plate 3 left and right in order to switch between the two fishing forces 7° 7'. Although it is not shown in the drawing, there is a structure in which the piston rond of a cylinder fixed to a table is connected to a sliding copper plate, and it is wound around a drum driven by a reducer motor with a brake. A structure is adopted in which both ends of the wire are connected to a sliding copper plate, and 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 can be changed by switching the power supply. Then, the sliding copper disks are alternately moved in opposite directions.

(In the drive mechanism A described above, in order to simplify the structure by using the same rack 9 for both the sliding copper plate 3 and the stationary copper plate 4, a carriage 5 is used that fastens the plane plates 3 and 4 with pins 6. Taka,
If the sliding copper plate 3 and the stationary copper plate 4 are individually provided with racks 9, the carriage 5 is not required.

B is a fixing means for stably holding the stationary adjustment device 4 in the cutting position, and a known mechanical device such as a set screw or a cam wedge may be used. If a rack 9 is provided on one side of the 4 and this rack 9 is engaged with the pinion 11 of the above-mentioned reciprocating machine A, the adjustment 4 can be fixed using the table 12 of the motor 10. It is also possible to use other reciprocating mechanisms by braking the motor or cylinder.

13 is a belt-type material feeding member installed oppositely on the table 1;
Suspended on a pair of rollers 14, 15, and rollers 14, 15
By changing the rotation direction of the material, the material feeding direction is alternately changed.

Reference numeral 16 denotes a suppressing member that is engaged with the back surface of the material feeding member 13 in correspondence with the sliding adjustment device 3 or the stationary adjustment device 4, and presses the workpiece material 17 against the adjustment device 3 or 4 to prevent blade escape during cutting. prevent it.

Reference numeral 18 denotes a rotation mechanism that drives the material feeding member 13, and the rotating direction is changed by switching the power supply, thereby rotating the material feeding member 13 in the forward or reverse direction.

PH is a phototube type that detects the end of the workpiece 17 on the front side of the cutter (limit switch or proximity switch can also be used)
This detector has a light projecting part and a light receiving part arranged opposite to each other with the table 1 in between, and emits a detection signal when the end of the workpiece 17 is removed from the light projecting path.

MSFI and MSRl are electromagnetic switches that change the operation of the adjustment reciprocating mechanism A, with MSFI being for forward movement and MSRl being for backward movement.

R is a relay that operates the brake 12 of the motor 10 in the reciprocating mechanism A when the motor 10 is stopped.

MSF2. MSR2 is an electromagnetic switch that switches the operation of the material feeding member rotation mechanism 18; MSF2 is for forward rotation, and MSR2 is for reverse rotation.

The LSI and LS2 are limit switches for detecting the position of the sliding adjustment device 3, the LSI detects the completion of the forward movement of the adjustment device 3, and the LS2 detects the completion of the backward movement.

T is a timer that sets the stop timing of the material feeding member rotation mechanism 18, and is activated when the detector PH detects the rear end of the workpiece 17, and when the rear end of the workpiece 17 comes off from the fittings 3 and 4. When this occurs, a time-up occurs and the rotating mechanism 18 is immediately stopped by the brake.

PB is a push button switch; turning it on starts the machine and turning it off stops it.

SSW is a selection switch, and by switching it, the workpiece 1
7 reciprocating cutting and one-way cutting using a wide plane.

Since one embodiment of the super-finishing device for woodworking according to the present invention is configured as described above, when performing reciprocating cutting of the workpiece 17, it fits into the bottom of the concave portion 2 in the table 1. A sliding adjustment 3 having two fishing forces 7, 7' in different directions is attached to the reciprocating table 5 which is linked to the reciprocating mechanism A using a mounting means 6 such as a pin, and the reciprocating mechanism is activated by the selection switch SSW. When cutting is selected and the pushbutton switch PB is turned on, the sliding adjustment mechanism 3 is operated by the reciprocating mechanism A to position the forward fishing force 5 at the cutting position, and when stopped by the limit switch LSI, the material is fed. Since the member 13 is rotated backward by the rotation mechanism A, if the workpiece 17 is fed onto the table 1 at this time, the workpiece 17 will be moved backwards over the forward-facing planer blade 7 by the feeder member 13. The lower surface of the material is cut.

When cutting is finished, the detector PH detects this and the workpiece 17
When the terminal comes off the adjusting device 3, the reciprocating mechanism A is instructed to operate in reverse, the sliding adjusting device 3 is moved so that it is positioned in the backward adjusting force 7' force S cutting position, and it is stopped by the limit switch SL2. When the material feeding member 13 is
is rotationally converted forward, the workpiece 17 is fed forward on the backward fishing force T by the material feeding member 13, its lower surface is cut again, and the workpiece 17 is sent to the front of the table 1.

However, if the finished surface is still uneven or has scratches after cutting twice, the fishing forces 7 and 7' must be switched and the material feeding member 13 must be reversed before feeding the workpiece 17. If so, one or more reciprocating cuts can be made to obtain a flat, scratch-free finished surface.

Also, when cutting a wide workpiece 17 of +4J, remove the sliding mixer 3 from the carriage 5 in the recess 2, and replace it with one fishing force 8 with a length commensurate with the table width. Attach the installed stationary adjustment device 4 with the attachment means 6 such as a pin, lock the reciprocating mechanism A with the fixing means B, fix the stationary adjustment device 4 at the cutting position, and use the selection switch SSW to perform one-way cutting of the wide material. When the selection is made and the pushbutton switch PB is turned on, the brake 1 of the motor 10 in the reciprocating mechanism A is activated by the relay H.
2 is applied, the reciprocating mechanism A becomes immobile and holds the stationary adjustment device 4 at the cutting position.At this time, the material feeding member 13 is rotated backward by the rotating mechanism 18, so the workpiece 17 is placed on the table 1. Once fed, the workpiece 17 is transferred backwards on the wide fishing force 8 and its lower surface is cut by the fishing force 8. When the cutting is finished, the detector PH detects this and the material feeding member 13
In order to reverse the process, the workpiece 17 is returned by sliding on the fishing force 8, and is cut only one way during the reciprocating process. It is possible to process a wide workpiece 17.

Even in this one-way machining, if unevenness or scratches remain on the finished surface after one cutting, before the workpiece 17 is sent out from the table 1, the material feeding member 13 is reversed and the feeding member 13 is turned again toward the fishing force 8. By feeding the workpiece 13 and cutting it twice or more, a flat and scratch-free finished surface can be obtained.

As described above, in the super-finished copper board for woodworking according to the present invention, a sliding mixer having two fishing forces in different directions is attached to a reciprocating table in a recessed part provided across the table by means of an attaching means. , the carriage is reciprocated by a reciprocating mechanism, and when the workpiece is sent backward, the forward fishing force is positioned at the cutting position, and when the workpiece is returned to the front, the backward fishing force is positioned at the cutting position. Not only is it possible to perform so-called reciprocating cutting of the workpiece both on the way back and forth, but also the position change of the sliding steel and the rotation change of the material feeding member can be controlled by the detector at the end of the workpiece. Since it is performed by detection, the above switching is performed as the cutting of the workpiece material is completed, and reciprocating cutting is performed continuously and automatically, which greatly reduces labor and improves efficiency in super-finishing work such as plates or square materials. Since the processed material is always returned to the operator's hand, the material can be supplied and taken out at the same place, which improves work efficiency and saves space. It is economical as it does not require any additional equipment.

In addition, instead of the sliding steel fittings, a stationary copper plate with a fishing force of a length commensurate with the width of the table is attached to the carriage in the concave part of the table, and the carriage is fixed by a fixing means to perform the adjustment. If the workpiece is held in the cutting position and only the rotation of the material feeding member by the rotation mechanism is changed based on the detection operation of the detector, the workpiece will be scraped by the fishing force only when it is sent backward, and when it returns to the front. What is called one-way cutting is performed without cutting, but in this case the fishing force used has a length close to the table width, so the full width of the table can be used effectively to process wide materials. The reciprocating cutting type, which is highly effective in saving labor and increasing the efficiency of the machine, is capable of machining wide materials with the simple operation of simply replacing the sliding steel fittings and stationary copper plate using the mounting means on the reciprocating table in the recessed part. It has the advantage of being able to conveniently and effectively finish machining from small square materials to wide boards by switching to a one-way cutting method suitable for
