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 pair of upper and lower holders for setting the direction of the cutting blade of the band saw, and these holders are rotated. It is characterized by being equipped with a rotating device that changes the twist angle given to the band saw, and a burr that rotates together with the holder. [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 direction of one side edge where the cutting blade of the band saw is formed can be reversed by rotating the holder, and since the burr also rotates with the holder, the direction of the cutting edge is always at the rear of the cutting part depending on the reversal of the cutting direction. located on the side. [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 carriage 1 has a pair of racks 12. which protrude in the conveying direction of the panel 9 and engage with the binions 13 and 13, respectively.
12, and the carriage 1 reciprocates in the transport direction of the panel 9 by the rotational drive of the pinion 13. The band saw 2 is also provided with a rack 22 that protrudes in the width direction of the panel 9, and the rotation of a pinion 23 that engages with the rack 22 causes the Panton-2 to reciprocate in the width direction of the panel 9 relative to the carriage 9. Now, Pantone-2 is composed of a base 20, an endless annular band saw 3, three pulleys 4, a pair of holders 5.5, and a burr 6. A boot whose axial direction is the same as the conveyance direction of the panel 9,
The band saw 3 attached to the pulley 4 and driven by the rotation of the pulley 4 has a cutting blade formed on one edge thereof, and therefore the cutting blade is driven with the cutting blade facing the conveying direction of the panel 9. However, a pair of vertically opposing 1-4
.. 4, the pair of holders 5.5 are twisted by 90 degrees so that one side edge where the cutting blade is formed is oriented in the width direction of the panel 9. As shown in FIG. 2, these holders 5.5 are constructed by housing a pair of rollers 51.51 on a base 50.
.. 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 8a 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, and a gear 84 that meshes with the intermediate gear 83. The cylinder 70 of the vertical telescopic unit 7 is fixed to the fixed plate 85. The vertically telescopic unit 7 is composed 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, barb removal 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 zero rotation device 8b that rotates around the axis
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, upper gear 8
4 is located on the extension line of the band saw 3, whereas the lower binion 88 is located at a position where the band saw 3 passes. Therefore, the lower binion 88 is provided with a notch 89 extending from its outer periphery to the center. The band saw 3 is configured to pass through this notch 89. As shown in FIGS. 3 and 4, the burr remover 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 It is formed from a pair of guide rollers 63, 63 placed on both sides of the rotary blade 62, and the rotary blade 62 is slidable in its axial direction, and is supported by compression springs 64, 64 placed on both sides. The two springs 64, 64, which are receiving spring force, are in a balanced state via the rotary blade 62. Therefore, in this cutting machine, the cutting operation of the panels 9 that are continuously manufactured is performed in the following steps, that is, while moving the carriage 1 at the same speed and in the same direction as the conveyance speed of the panels 9,
The panel 9 is cut by moving the Pantone-2 forward in the width direction of the panel 9 relative to the traveling platform 1. When this cutting is completed, the traveling platform 1 is returned to the initial position and both of the above-mentioned By rotating the holder 5.5 by 180 degrees, the direction of one side edge where the cutting blade of the band saw 3 is formed is reversed, and after that, while moving the traveling table 1 in the transport direction of the panel 9, the traveling table 1 is moved. The panel 9 is cut by moving the Pantone-2 backwards with respect to the table 1. Then, the traveling table 1 is returned to the initial position, and both holders 5 and 5 are rotated 180 degrees again, and the direction of the band saw 3 is undo. By repeating this cycle, the continuously manufactured panels 9 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. At this time, even if the cutting portion 95 of the panel 9 meanders due to the vibration of the band saw 3, the rotary blade 62 is pushed by the springs 64, 64 from both sides as described above and can slide freely in the axial direction. Therefore, as shown in FIG.
The burr treatment on any of the cut surfaces is done beautifully. 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.
