摘要： A filter unit is connected between a tray and a discharging duct of a spiral conveyor. The filter unit includes a first filter (perforated metal) that is fixed at a position close to the outer periphery of a conveying spiral, and a second filter (mesh filter) that rotates on the outside of the conveying spiral and the first filter. A washing nozzle sprays a washing liquid on the second filter. The chips captured by the first filter are scraped by the rotating conveying spiral and delivered back to the conveying path and the chips passing through the first filter but captured by the second filter are removed by the washing nozzle and delivered back to the conveying path. The washing liquid is sprayed at a predetermined angle from the washing nozzle and collides with vanes arranged on the outer periphery of the second filter and provides rotational force on the second filter.

摘要： [Problem] To provide a bending device with a novel structure capable of efficiently bending a metallic plate without scratching or denting the plate.[Solution] A device (10) for bending a metallic plate (W) mounted on a pair of movable plates (35, 35) by applying pressing force to the metallic plate by an upper die (20) along a central axis (X), wherein against the biasing force of a coil spring (45), the movable plates move with the extension of the metallic plate during bending, and therefore the metallic plate is not scratched. The upper surface of each of the movable plates is a perfect flat surface, and therefore does not dent the metallic plate being subjected to the pressing force by the upper die. When the pressing force and the load of the metallic plate are removed after the completion of bending, swing members return to the original position thereof, and the movable plates are also returned to the original position thereof by the biasing force of the coil spring, with top parts (42) of fastening members (41) coupling the movable plates to fixed plates (38) functioning as a stopper and holding the movable plates at the original position.
摘要翻译： 本发明提供一种具有能够有效地弯曲金属板而不会刮板或凹陷的新型结构的弯曲装置。 [解决方案]一种用于通过沿着中心轴线（X）的上模（20）向金属板施加按压力来弯曲安装在一对可动板（35,35）上的金属板（W）的装置（10） ，其中抵抗螺旋弹簧（45）的偏置力，可动板在弯曲期间随着金属板的延伸而移动，因此金属板不被划伤。 每个可移动板的上表面是完美的平坦表面，因此不会使金属板受到上模受压力的影响。 当完成弯曲之后去除金属板的按压力和负载时，摆动构件返回其初始位置，并且可动板也通过螺旋弹簧的偏压力返回到其原始位置， 紧固构件（41）的顶部（42）将可移动板联接到用作止动器的固定板（38）并将可动板保持在原始位置。

摘要： A novel structure of a spiral conveyor is provided which is also suitable for conveyance of curl-shape and permanent-shape cuttings in a lathe system while suppressing the occurrence of noise caused by vibration. At the lowest point, a conveyance spiral of this spiral conveyor for conveying chips contacts the ground (the ground point P) at the lowest point of a tray, and the conveyance spiral not in contact with a pair of rails in opposite positions on the inner surface of the tray and extending in the length direction, and small gaps t are formed between the conveyance spiral and the rails. Because it is only at the lowest point that the conveyance spiral contacts the tray, similarly to conventional rail-less designs, a low level of noise is achieved, similar to that in the rail-less designs.
