Description

[Detailed Description of the Invention] The present invention can cut plywood by moving a circular saw along a rail.
This relates to machines that cut plate materials such as flash, hardboard, and plastic boards.

As is well known, there are two types of machines for cutting plate materials using a circular saw: a type in which the plate is moved, and a type in which the circular saw is moved while the plate is fixed.

The former has a simple mechanical structure, but has a serious drawback in that it requires a large area when cutting a wide plate.

In addition, the latter requires a rail for reciprocating the circular saw and a slider for the drive, so the structure is generally complicated.

On the other hand, recently, cutting the board at an angle to the surface of the board has become increasingly common, especially in the field of high-end wooden furniture. In the J type, there was nothing that could be adapted to such a descendant requirement.

The 11IIJ type plate material cutting machine of the present invention has been developed in view of the above-mentioned problems, and the plate material for processing is superimposed on the surface of a No'H channel in which saw grooves are provided longitudinally, and a circular saw blade is made to protrude from the saw grooves. The plate material for processing is cut by moving the circular saw along the saw groove, and two straight rails parallel to the saw groove are fixed to the back of the panel, and a reciprocating machine is mounted on the straight rails. A movable underframe is provided, and an arcuate rail curved at a curvature such that the panel surface portion of the gold layer groove is the center of rotation is fixed to the underframe so as to be located in a plane orthogonal to the saw groove. A saw mounting board is provided so as to be able to slide freely on the circular arc-shaped rail, and a circular saw and its rotating motor are provided on the saw mounting board so that the circular saw blade can freely move in and out of the saw groove. This enables a movable saw-type plate cutting machine to cut a plate with the cutting surface inclined to the plate surface.

Next, one embodiment of the present invention will be described in detail with reference to the drawings.

This embodiment is a vertical plate cutting machine commonly called a panel saw, and a panel 2 is attached to the front of a machine frame 1 slightly tilted backwards, and a roller conveyor is installed horizontally near the lower edge of the front of the panel. 3 has been deleted.

The panel 2 is provided with saw grooves 4 longitudinally.

On the back of the panel 2, two straight rails 5.5 parallel to the saw grooves 4 are fixed to the machine frame 1 at a predetermined interval. 6
is an underframe provided so that it can freely reciprocate above the linear rail 5.5, and there are saw grooves 4 at the upper and lower edges of the underframe.
A pair of arcuate rails 7, 7 each curved with a curvature such that the panel surface portion a is the center of rotation is fixed so as to be located within a plane perpendicular to the saw grooves 4. The arc-shaped rail 7.7 is about ≠7/7
The length of a circle has a concave cross section, and each is fixed to the underframe 6 so that its concave portions face each other. 8 is a saw mounting board, and a slider 9 with a length of 7 yen corresponding to approximately g is protruded from the upper and lower parts of the saw mounting board.
, 9 are slidably fitted into the recesses of the arcuate rails 7.7, so that the saw mounting plate 8 can pivot freely in a plane perpendicular to the saw grooves 4. In addition to the arcuate rails 7.7, the underframe 6 is provided with a gear box 11 that reduces the output rotation speed of the servo motor 10 and the nuclear motor 10, and the output shaft of the gear box 11 is provided with a bevel gear. . Then, a hollow shaft 15 is pivotally supported with a pin 14 on a bracket 13 protruding from a part of the back surface of the saw mounting board 8, a threaded shaft 16 is screwed into the hollow shaft 15, and the threaded shaft 16 is screwed into the hollow shaft 15. A bevel gear 17 fixed to the end is meshed with the bevel gear. The motor 10 is rotated, and the rotation is caused by the gearbox 11. When the transmission is transmitted to the screw shaft 16 via the bevel gear J17, the screwing position between the screw shaft 16 and the hollow shaft changes and the overall length expands and contracts, so that the saw mounting board 8 is moved along the arcuate rail 7.7. can be rotated. Guide rails 18.38 are formed on the upper and lower edges of the back of the saw mounting board 8, and a motor base 9 is slidably fitted to the guide rails 18.18, and a motor for rotating the saw is attached to the motor base 19. be fixed. The rotary shaft n of the motor protrudes from a notch cut in the first part of the saw mounting board 8, and a circular saw is fixed at the tip of the rotary shaft η. Reference numeral 25 designates a cover integrally provided on the front surface of the saw mounting board 8 so as to surround the circular saw U. In addition, an air cylinder provided at the back of the saw mounting board 8 connects its operating shaft to the back of the motor base 19, and by operating the air cylinder, the motor base 19 moves to the guide rail 18.
It is designed so that it can move forward and backward along 18. shirts) 27 at the upper and lower end portions of the straight rails 5, 5, respectively.
．． 28 is installed horizontally on the shaft, a chain 3] is wound around a blue sprocket J30, and fixed to the underframe 6 at both ends of the chain 31. Reference numeral 32 denotes a motor that rotates the shaft path, and a sprocket ring fixed to the rotating shaft of the motor and the shaft field are linked by an endless chain 2a.

In addition, the part is a balance weight, and the balance weight is fixed to the chain by hanging it from the sub-block 36 which is pivotally supported on the upper part of the back surface of the machine frame 1, and the other end of the chain J is attached to the shaft n. It is fixed to the underframe 6 via a fixed sprocket, and by substantially balancing the weight of the balance weight section and the weight of the underframe 6, the underframe 6 can smoothly move up and down along the straight rail 5.5. I'm trying to get it. A plug is provided on the front surface of the panel 2, with both ends fixed to the upper and lower edges of the front of the panel 2 in such a way as to cover the saw groove 4, and a pressing member blade with a concave cross section is provided in the frame. is provided so that when the processing plate material 40 is superimposed on the front surface of the panel 2, the processing plate lead can be pressed onto the panel surface by the pressing member blade. 41 operates the pressing member (material). An air cylinder 42 indicates switches for operating the motors 10, 20, air cylinders 41, etc.

In the cutting machine configured as described above, the plate material for processing carried in while being supported by the roller conveyor 3 is positioned at the required cutting part of the plate material for processing in the saw groove 4, and the plate material for processing is cut by the pressing part. At the same time as overlapping and fixing chrysanthemums on two panels, motor 1
0, the saw mounting plate 8 is rotated to tilt the circular saw at a desired angle with respect to the cutting plate material. (The imaginary line in Figure 3 shows the saw mounting board 8 tilted to +51")
. Then, the circular saw U is rotated at high speed, the operating shaft of the air cylinder device is extended, and the motor base 19 is advanced to cause the circular saw separate blade to protrude from the saw groove 4, while the underframe 6 is moved to the linear rail 5 by the drive of the motor d. This is to cut a processing plate material ship by moving it along the line 5. The angle of inclination of the cut surface can be adjusted arbitrarily within the range of +j' by changing the screwing angle between the shaft 6 and the hollow shaft 15 and rotating the saw blade 8 along the arcuate rail 7.7. can be varied.

In this way, the moving weight type plate material cutting machine of the present invention cuts an arcuate rail having a curvature such that the saw groove part is the rotation center on the underframe which is reciprocally movable on a straight rail, in a plane orthogonal to the saw groove. A saw mounting board equipped with a circular saw and a motor for rotating the circular saw is provided so as to be able to slide freely on the arcuate rail, so that the circular saw can rotate around the saw groove in a plane perpendicular to the saw groove. Therefore, the plate material for processing can be cut to obtain a cut surface having a desired angle. Therefore, according to the present invention, the two straight rails parallel to the bell groove are always in a fixed state, and only the saw mounting plate is tilted, so that the required movement due to the tilting is possible. Portion is small 1
, from that l? This has the advantage that the overall construction is relatively simple.
