Abstract: This application relates to a self-contained apparatus for mechanically turning individual workpieces travelling on a conveyor, such as lengths of lumber travelling into or exiting from a sawmill. The invention reduces the need for lumber graders to turn lumber manually and thereby helps avoid repetitive motion injuries. The apparatus includes an adjustable height frame which is positionable alongside the conveyor. The frame supports a workpiece holder defining an open-ended slot for temporarily receiving an end portion of a workpiece. When the end of a lumber board or other workpiece is received within the holder, a proximity sensor causes the holder to rotate, thereby turning the workpiece lengthwise 180 degrees. The workpiece is then deposited on to the conveyor in its inverted orientation for further travel thereon. The apparatus may also optionally permit workpieces to pass through the holder when a “skip” rather than an “invert” signal is received. The workpiece holder may be connected to a rotatable shaft driven by an electric or hydraulic motor.

Abstract translation: 本申请涉及一种用于机械地转动在输送机上行进的单个工件的独立设备，例如木材进入或离开锯木厂的长度。 本发明减少了对木材分级机手动切割木材的需要，从而有助于避免重复的运动损伤。 该设备包括可调节的高度框架，其可以沿着输送机定位。 框架支撑限定用于暂时接收工件端部的开口端口的工件保持架。 当木质板或其他工件的端部被容纳在保持器内时，接近传感器使保持器旋转，从而使工件纵向180度转动。 然后将工件以其倒置的方向沉积到输送机上，以进一步行进。 当接收到“跳过”而不是“反转”信号时，该装置还可以可选地允许工件通过保持器。 工件保持器可以连接到由电动或液压马达驱动的可旋转轴。
