    • Anti-collision system for a machine (1) for machining workpieces of wood or similar materials, said machine (1) including a tool (2) and a machine part (9, 10, 11) positioned near said tool (2), the tool (2) and the machine part (9, 10, 11) being movable one relatively the other.
      In order to make this anti-collision safer, there are provided electric conducting elements (12) projecting at least partially from said machine part (9, 10, 11), an electric voltage generator (13) for feeding a potential difference between the electric conducting elements (12) and said tool (2) and a control system (15) configured in such a way as to detect, substantially at a distance between the tool (2) and the electric conducting elements (12), a current passage between the electric conducting elements (12) and the tool (2), and to emit a corresponding anti-collision control signal (14) as said current passage is detected.

    • In a tilting table indexing device driven by a direct-drive motor, a tilting table is prevented from rotating beyond an allowable rotation range when power is shut off in an emergency, such as power outage, and thus a breakage accident of, for example, a tool or a workpiece is reliably prevented from occurring. In a tilting table indexing device (1), in which a rotary member (3) such as a table (4) is rotated within a predetermined normal rotation angle range by a direct-drive motor (9) to tilt the table (4) and in which the tilted table (4) is held by activation of a holding mechanism (10), an elastically displaceable member (11) having a pressure receiving surface (12) is provided at one of the rotary member (3) and a frame (6) of the tilting table indexing device (1), and an engaging portion (13) capable of contacting the pressure receiving surface (12) is provided at the other of the rotary member (3) and the frame (6). When the rotary shaft (5) rotates beyond the normal rotation angle range because of free rotation of the rotary member (3) in an emergency, the elastically displaceable member (11) absorbs the kinetic energy of the rotary member (3) and stops the rotary member (3) before a danger angle range.
    • 在由直接驱动电动机驱动的倾斜台分度装置中,在诸如断电等紧急情况下的电力切断时,防止倾斜台旋转超过允许旋转范围,因此,例如, 可靠地防止工具或工件发生。 在通过直接驱动电动机(9)使工作台(4)的旋转体(3)在预定的正常旋转角度范围内旋转以使工作台(4)倾斜的倾斜台分度装置(1)中, 并且其中通过启动保持机构(10)来保持倾斜台(4),具有受压表面(12)的可弹性位移的构件(11)设置在旋转构件(3)和框架 (1)的倾斜台(6)和与压力接收表面(12)接触的接合部分(13)设置在旋转部件(3)和框架(6)的另一个处。 由于旋转构件(3)在紧急情况下自由旋转,当旋转轴(5)旋转超过正常旋转角度范围时,弹性位移构件(11)吸收旋转构件(3)的动能并停止 旋转构件(3)在危险角度范围之前。
