    • A paper shredder having shredder cover and a motor coupled to shredder blades includes a shredder throat coupled to an inlet in the shredder cover and in proximity to shredder blades. The shredder throat has a moveable throat blade, which widens the shredder throat. An anti-jam switch, which when activated causes the motor to advance the shredder blades to clear a jam in the widened shredder throat. The jam clearing mechanism can be automatic or manual, as by push-button or turn-knob linkages. A method for recovering from a shredder jam in a paper shredder is provided, including providing a moveable throat blade; sensing a shredder throat jammed condition; releasing the moveable throat blade; moving the moveable throat blade to a wide gap position; sensing the moveable throat blade in the wide gap position; advancing shredder blades in response to the sensing, by which the jammed condition is cleared.
    • 具有粉碎机盖和与粉碎机叶片连接的马达的纸粉碎机包括与切碎机盖上的入口连接并且与切碎机叶片接近的切碎器喉部。 粉碎喉咙有一个可移动的喉咙叶片,可以使切碎的喉咙变宽。 防卡合开关,当被激活时,电动机推进切碎机刀片以清除加宽的切碎机喉部的卡纸。 卡纸清除机构可以是自动的或手动的,如通过按钮或旋钮连接。 提供了一种从切碎机中的切碎机堵塞的方法,包括提供可移动的喉叶; 感测碎纸机喉咙堵塞状况; 释放可移动的喉叶; 将可移动的喉舌移动到宽的间隙位置; 在宽间隙位置感测可移动的喉叶; 响应于感测而推进粉碎刀片,由此清除卡住的状况。

    • A shredder includes a housing having an opening for the insertion of media to be shredded. A cutting assembly for the shredding of media is disposed in the housing. A media detector including an infrared emitter and an infrared sensor is disposed about the opening for the detection of the presence of media to be shredded in the opening. A controller is disposed in the housing and is in responsive communication with the media detector for controlling the operation of the cutting assembly. The controller is programmed with a dynamic media detection threshold that is at least in part passed upon an emission sensed value and a background sensed value.
    • 切碎机包括具有用于插入要切碎的介质的开口的壳体。 用于粉碎介质的切割组件设置在壳体中。 围绕开口布置有包括红外发射器和红外传感器的介质检测器,用于检测在开口中要切碎的介质的存在。 控制器设置在壳体中并且与介质检测器响应地通信以控制切割组件的操作。 控制器被编程有动态媒体检测阈值,其至少部分地基于发射检测值和背景感测值。

    • A comminuting rotor is driven by a rotary current electric motor via a non-positive traction drive, wherein said rotary current electric motor is energized by a controlled frequency converter for operating the comminuting rotor at a predetermined rotational speed during the normal operating phase. A degree of slip of the traction drive is determined and monitored and the rotary current electric motor is controlled for being powered off if a first slip threshold value is exceeded. If a predetermined second threshold of the traction drive slip is exceeded, which is below said first slip threshold, for continuing the operation of the comminuting device, the frequency converter is controlled in a slip operating phase for a closed or open loop control of the traction drive slip to a predetermined third slip threshold value and for reducing the torque output from the rotary current electric motor.
    • 粉碎转子由旋转电流电​​动机通过非正向牵引驱动驱动,其中所述旋转电流电​​动机由受控变频器激励,用于在正常操作阶段期间以预定转速操作粉碎转子。 确定并监视牵引驱动器的滑动程度,并且如果超过第一滑移阈值,则控制旋转电流电​​动机以断电。 如果超过牵引驱动滑差的预定的第二阈值,低于所述第一滑差阈值,则为了继续粉碎装置的操作,变频器被控制在滑动运行阶段以用于牵引力的闭合或开环控制 驱动滑移到预定的第三滑移阈值,并且用于减小从旋转电流电​​动机输出的扭矩。
