Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a super-finishing silver disc for woodworking that performs reciprocating cutting and wide cutting using a double sliding silver disc. A plurality of sliding silver plates with forward-facing and backward-facing blades attached side by side are fitted into the recesses provided, and the second-class sliding silver discs are reciprocated by a reciprocating mechanism to separate the forward-facing blades and rear-facing blades respectively. At the same time, the rotating direction of the material feeding member provided on the table is changed accordingly, and the material is transferred back and forth, so that the material is overlapped back and forth in both directions. By cutting the material with multiple blades and cutting the material at least four times in each stroke, the standard cutting amount can be set at least four times as much per stroke, resulting in a dramatic increase in work efficiency. In addition, by pressing the small cutting amount setting, the cutting amount per turn is reduced as much as possible, reducing the back-eye phenomenon, and achieving the same efficiency as conventional reciprocating cutting. To measure vast improvements.

A plurality of sliding silver disks are operated by a reciprocating mechanism so that the forward-facing blade and backward-facing blade are shifted to the left and right and are alternately positioned at the cutting position, and the material feed provided on the table accordingly. By changing the direction of rotation of the part, moving the material back and forth, and processing each hand with multiple blades that are shifted left and right in both directions, it is possible to produce a wide material that is equivalent to the number of blades in a single blade. Perform reciprocating processing.

By moving multiple sliding silver disks using a reciprocating mechanism and changing the combination of forward-facing and backward-facing blades supported by these, multiple reciprocating cuts and wide cutting functions can be performed by remote control. , to improve workability and efficiency.

By rotating the material feeding member in forward and reverse directions using a reversible drive mechanism to perform reciprocating cutting of the material, it is possible for one worker to process the material, saving labor and eliminating the need for a pre-cutting device, etc. and save equipment costs and equipment space.

It is in. Next, in order to show an embodiment of a super-finishing silver plate for woodworking which performs multiple back-and-forth cuts and wide cutting using the double-type silver plate according to the present invention, the following will explain it with reference to the drawings.

1 in the figure is a table for a super-finishing silver plate for woodworking, and a concave part 2 in the center where two sliding silver plates (to be described later) are fitted side by side.
It is provided so that it is diagonal to the material feeding direction.

Incidentally, this recessed portion 2 may be formed in sections so that sliding silver discs can be fitted thereinto one by one.

3 and 3' are two sliding silver discs that are slidably fitted into the concave part 2, and are formed to have a length approximately twice the length of the concave part 2, and have one side facing forward and the other side of each disc. The rear-facing blades 4 and 4' are installed side by side.

(Although the arrangement of the cutlery 4, 4' may be the same for both sliding silver discs 3, 3', it is preferable that the arrangement be reversed for the silver discs 3 and 3'.

) A, A' is a reciprocating mechanism that reciprocates the sliding silver discs 3, 3' from side to side in order to use the double blades 4, 4' interchangeably.A rack 5 is attached to the silver discs 3, 3', and this rack A structure in which a pinio/7 driven by a motor 6 with a brake is engaged with 5, or a structure in which a piston rond of a cylinder fixed to a table is connected to a sliding silver disk, although it is not shown in the drawing, is a sliding mechanism. A structure in which a screw motor is screwed onto a screw shaft suspended horizontally at the bottom of the silver plate is adopted, and when a motor is used, the direction of rotation is changed by switching the power supply, and the sliding silver plates 3 and 3' are reciprocally operated. Move to the left or right.

(In addition, the sliding silver discs 3 and 3' are arranged so as to sandwich the pinion 7, and the racks 5.5 attached to both silver discs 3 and 3' are connected to the pinion 7.
When meshed on both sides, one pinion 7 can mutually operate the two silver discs 3, 3'.

) 8 is 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.

11 is a pressing member engaged with the back surface of the material feeding member 8 in correspondence with the sliding silver discs 3, 3' to push the workpiece 12 onto the sliding silver discs 3, 3'.
3' to prevent the blade from running away during cutting.

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

The pH sensor is a phototube type that is placed on the front side of the cutter and detects the end of the workpiece 12 (a limit switch or proximity switch can also be used)
The detector has a light emitting part and a light receiving part facing each other with the table 1 in between, and emits a detection signal when the end of the workpiece 12 is removed from the light projection path.

LSI, LS2°LS3. LS4 and LS5. LS6. L
S? , LS8 are position setting switches for the sliding silver discs 3, 3', LSI to LS4 position the sliding silver discs 3 and 3' so that the respective forward and backward blades overlap at the cutting position, and LS5 to LS8 are position setting switches for the sliding silver discs 3 and 3'. The distance between the pair of switches is determined so that the moving silver plate 3° 3' is positioned so that the forward and backward blades 4, 4' are shifted from side to side.

The spacing between the sliding plates 3 and 3' can be set by digital control, a storage device, etc., rather than by limit switches as described above.
Although it can be done using other methods, since these are publicly known, a brief explanation of the drawings will be omitted.○S
S is a selection switch, and the above two sets of position setting switches LS
I to LS4 and LS5 to LS8 are selectively inserted into the electric circuit of the reciprocating mechanism A, and multiple cutting and wide cutting are selected.

T is a timer for setting the stop timing of the material feeding member rotation mechanism 13, which is started when the detector pH detects the rear end of the workpiece 12, and is timed up when the rear end of the workpiece 12 comes off the cutter 4. Then, the rotating mechanism 13 is immediately stopped by the brake.

pB is a push-button switch; turning it on will start the machine, and turning it off will stop it.

Since one embodiment of the woodworking superfinishing silver disc according to the present invention is configured as described above, when selecting multiple cuts in the reciprocating stroke using the selection switch SS, the sliding silver discs 3, 3'
Since the position setting switches LSI to LS4 are inserted into the electric circuit of the reciprocating mechanism A, if the push button switch pB is turned on in this state and the machine is operated, the material feeding member 8 will be rotated backward by the rotation mechanism 13. At the same time, the two sliding steels 3, 3' are moved in opposite directions by the reciprocating mechanisms A, A', and the forward-facing blades 4, 3' provided on each are moved in opposite directions.
4 are overlapped back and forth at the cutting position as shown in FIG. Then, the workpiece 12 moves over the forward-facing double blades 4, 4 due to the rotation of the material feeding member 8, and its lower surface is cut twice in succession, and when the cutting is finished, the detector pH is Detecting this, the reciprocating mechanisms A and A' are immediately instructed to reverse operation, and the reciprocating mechanisms A and A' move the sliding silver discs 3,
3' in the opposite direction to the above, and the rear-facing blades 4 and 4' provided on each are overlapped back and forth at the cutting position as shown in Figure 4 of the drawing, and the limit switch L
S2 and LS3 detect this, stop the reciprocating mechanisms A and A', and accordingly, the rotation mechanism 13 rotates the material feeding member 8 forward, so that the material 12 to be subjected to force is rotated toward the material feeding member 8. Due to the reversal of the
, 41, the lower surface is cut twice, and -
Since the cutting process is performed four times in the stroke and then sent out to the front of the table 1, if the cutting amount of each blade is set to the standard straight, the cutting amount will be four times as much in the -stroke and the work efficiency will be increased. In addition, by setting the cutting amount of each blade to a very small amount, the amount of cutting per cut can be minimized, reducing the back-eye phenomenon and reducing work efficiency. It is possible to obtain a good finished surface from a material that tends to have adverse grains without causing any damage.

Furthermore, when wide cutting in the reciprocating stroke is selected using the selection switch sS, the switch switches LS5 to LS8 are inserted into the electric circuit of the reciprocating mechanism A, so if the machine is operated in this state, the rotating mechanism 13 Material feeding member 8
is rotated backward, and the reciprocating mechanisms A, A'
The two sliding silver discs 3, 3' are driven, and the forward-facing blades 4, 4 provided on each are pushed to the cutting position and shifted to the left and right as shown in Figure 5 of the drawing, and the two blades 3, 3' are pressed to the cutting position, as shown in Figure 5 of the drawing. (double-edged weapon 4,
4 is overlapped, so it is not doubled). Therefore, if the workpiece 12 is fed onto the table 1 at this time, the workpiece 12 will be transferred onto the table 1 by the material feeding member 8. is transferred backwards, and the left half is cut by the left cutter 4, and the right half is cut by the right cutter 4. When cutting is finished, the detector pH detects this and commands reverse operation, so the reciprocation is performed. Mechanism A is reversed and moves the sliding silver discs 3, 3' in the opposite direction to the above, and the backward-facing blades 4' provided on each
, 4' are shifted to the left and right in the cutting position to form a double-width knife with approximately double width.
is sent forward on the table 1, and the left half is cut by the left cutter 4', and the right half is cut by the right cutter, respectively.When the cutting is finished, it is sent forward on the table 1, so in this case it is a reciprocating process. In the process, it is possible to perform a wide cut that is approximately twice the width of a single knife.

In addition, in this case, the reversible rotation mechanism 13 is linked to the material feeding member 8, and when the cutting of the workpiece 12 by one-way feeding is completed,
Since the material feeding member 8 is reversed and the workpiece 12 is returned to the operator's hand, the workpiece can be moved by one worker without using a pre-picking operator or a pre-picking device. This allows for easy processing.
