Abstract

PURPOSE:To perform a reciprocating cutting and to shorten the cutting intervals of a panel by equipping a holder for setting the direction of the cutting edge of a band saw and a turning device changing the twist angle given to the band saw by turning this holder, in the cutting machine equipped with a band saw on whose one side edge a cutting edge is formed. CONSTITUTION:When a hydraulic cylinder 80 in a turning device 8a is driven, the pinion 82 and gear 84 biting with a rack 81 are rotated, and a vertically expansion unit 7, the upper part holder 5 and a chambering 6 are rotated centering around the shaft of the gear 84 as well. Since the axes of the gear 84 and pinion 88 become at the same place as the position of a band saw 3 between the vertically opposing pulleies 4, 4, the band saw 3 is also changed at its direction of one side edge on which the cutting edge is formed, in case of the upper and lower both holders 5, 5 changing their directions by synchronous rotation. The burr to the upper part is removed by the rotating edge 62 of the chamfering 6 coming into contact with the panel 9 surface by chasing the cutting part at all times by rotating together with the holder 5.

Accordingly, the present invention provides a cutting machine equipped with a band saw having a cutting blade formed on one side edge, and includes a holder for setting the direction of the cutting blade of the band saw, and a holder for setting the direction of the cutting blade of the band saw. It is characterized in that it includes a rotation device that changes the twist angle. [Function] According to the present invention, although cutting is performed using a band saw, the holder for setting the direction of the cutting blade of the band saw can be rotated, so that the direction of cutting of the object to be cut is set. The orientation of one side edge where the cutting blade of the band saw is formed can be reversed by rotating the holder. [Example] The present invention will be described in detail below based on the illustrated example.
This running cutting machine is installed in a continuous production line for panels 9 filled with . A traveling platform 1 is disposed on the traveling platform 1 via a linear bearing 11, and a Pantone-2 is disposed on the traveling platform 1 via a linear bearing 21 so as to be freely movable in the width direction of the panel 9, which is orthogonal to the conveying direction of the panel 9. It is composed of. The traveling platform 1 has a pair of racks 12. which protrude in the conveying direction of the panel 9 and mesh with pinions 13.13, respectively.
12, and the carriage 9 reciprocates in the conveyance direction of the panel 9 by the rotational drive of the pinion 13. Furthermore, the Pantone-2 is equipped with a rack 22 that projects in the width direction of the panel 9, and the band saw 2 is reciprocated in the width direction of the panel 9 with respect to the carriage 1 by rotation of a pinion 23 that meshes with this rack 22. Now, the band saw 2 is composed of a base 20, an endless annular band saw 3, three pulleys 4, a pair of holders 5, and a burr 6. A band saw 3 is attached to a pulley 4 whose axial direction is in the same direction as the conveying direction of the panel 9 and is driven by the rotation of the pulley 4.
has a cutting blade formed on one side edge thereof, and for this reason, the cutting blade is driven in a state facing the conveying direction of the panel 9. However, a pair of pulleys 4, which are vertically opposed to each other, are driven.
4, the panel 9 is twisted by 90° so that the direction of one side edge where the cutting blade is formed by the pair of holders 5, 5 is in the width direction of the panel 9. These holders 5.5, as shown in FIG.
.. 51 changes the direction of the band saw 3. Here, the upper holder 5 is supported via the vertical telescoping unit 7 and a rotating device 8a, and the lower holder 5 is supported via a rotating device 8b. The rotating device W8a consists of a rack 81 that is reciprocated by a hydraulic cylinder 80, a pinion 82 that meshes with the rack 81, an intermediate gear 83 that rotates together with the pinion 82, a gear 84 that meshes with the intermediate gear 83, and a gear 84 that meshes with the intermediate gear 83. The tube 70 of the vertical telescoping unit 7 is fixed to the plate 85 fixed to the plate 84 . The vertically telescopic unit 7 consists of the cylinder 70, a rod 71 that is vertically movable within the cylinder 70, and a hydraulic cylinder 72 fixed to the outer surface of the cylinder 70. It is connected to the upper end of a rod 71 that protrudes from the upper end. The holder 5 is fixed to the lower end of the rod 71. Also, the barbage 6
is also fixed to the lower end of this rod 71. The other rotating device 8b consists of a rack 87 that is reciprocated by a hydraulic cylinder 86 and a pinion 88 that meshes with the rack 87, and the pinion 88 is fixed to the lower holder 5. . Now, if the hydraulic cylinder 80 in the rotation device 8a is driven, the binion 82 and gear 84 that engage with the rack 81 will rotate, and the vertical telescoping unit 7 and the upper holder 5 and burr 6 will also rotate. Hydraulic cylinder 86 in single rotation device 8b rotating around axis 84
When driven, the rotation of the pinion 88 causes the lower holder 5 to also rotate around the axis of the pinion 88. At this time, since the axes of the gear 84 and the pinion 88 are at the same position as the band saw 3 between the upper and lower opposing pulleys 4, 4, both the upper and lower holders 5, 5 rotate synchronously to change their orientation. When changing, the band saw 3 also changes the direction of one side edge where its cutting blade is formed. In addition, the upper gear 8
4 is located on the extension line of the band saw 3, whereas the lower pinion 88 is located at the passing position of the band saw 3. Therefore, the lower pinion 88 is provided with a notch 89 extending from its outer periphery to the center. , the band saw 3 passes through this notch 89. As shown in FIG. 3, the burr storage 6 includes an arm 60 fixed to the lower end of the rod 71, a rotary blade 62 rotatably driven by a speed controllable motor 61 attached to the arm 60, and this rotary blade. It is formed from a pair of guide rollers 63°63 arranged on both sides of the roller 62. Therefore, in this cutting machine, the cutting operation of the panels 9 that are continuously manufactured is performed in the following procedure, that is, while moving the carriage l in the same direction at the same speed as the conveyance speed of the panels 9,
The panel 9 is cut by moving the band saw 2 forward in the width direction of the panel 9 with respect to the traveling table 1. When this cutting is completed, the traveling table 1 is returned to the initial position and both the holders are removed. 5, 5 by 180°, the direction of one side edge where the cutting blade of the band saw 3 is formed is reversed, and then, while moving the traveling table l in the conveying direction of the panel 9, By moving the band saw 2 backward relative to the panel 1, the panel 9 is cut. Next, the traveling table 1 is returned to the initial position, and both holders 5, 5 are rotated 180 degrees again to return the band saw 3 to its original orientation. By repeating this cycle, the panels 9 that are continuously manufactured are cut into required lengths. Furthermore, the drive of the band saw 3 at this time is such that the panel 9 is cut from the bottom to the top as shown by the arrow in the figure, and by driving the band saw 3 in this way, the upper side of the panel 9 The upward burrs generated on the surface plate 90 are removed by the rotary blade 62 of the burr remover 6, which rotates together with the holder 5 and always follows the cut portion and comes into contact with the surface of the panel 9. Note that the holders 5, 5 perform reciprocating rotation of 180° as described above, but at the intermediate rotational position of 90°, the band saw 3 is in a state where no twist is applied. If the band saw 3 can be set in the same state, the band saw 3 can be easily replaced. In addition, since the band saw 3 is driven from the bottom to the top as described above, the burr 6 is also provided on the upper holder 5, but when the band saw 3 is driven from the top to the bottom, A burr 6 may be provided on the side holder 5. As described above, in the present invention, although cutting is performed using a band saw, the cutting blade of the band saw is formed so that the holder for setting the direction of the cutting blade of the band saw can be rotated. By reversing the direction of one side edge by rotating the holder, it is possible to cut in the opposite direction, and in a running cutter, the cutting interval of the object to be cut can be shortened. It also makes it easier to replace the band saw.
