摘要： Control apparatus controls the operation of a trailing edge folder in a carton blank folding machine. The folding machine has conveyor means for continuously advancing blanks in a predetermined direction in untimed relationship to one another along a generally horizontal path. The trailing edge folder has a rotatable shaft mounted below and transverse to the path. The shaft has mounted thereon for rotation therewith one or more arms which extend outwardly from the axis of the shaft. Folding heads extend from the distal ends of the arms. The control apparatus has a sensor which produces a trailing edge signal indicating the departure of the trailing edge of a blank from a first location along the path upstream of the folder. At the end of a determined interval after the trailing edge signal the shaft is rotated in the direction in which the carton is travelling so that a head on the shaft comes into contact with the trailing panel of the blank, and folds it over about 180.degree.. The shaft is stopped there until the carton panel slides out from under and out of the path of travel of the head. The shaft is then rotated further to a dwell position beneath the path and stopped at that point until the next blank is sensed. The control apparatus may be adjusted for different machine speeds, and differently sized cartons. Circuitry for monitoring operation, for making adjustments, and for detecting and diagnosing malfunctions is also provided.

摘要翻译： 控制装置控制纸箱折页机中的后缘文件夹的操作。 折叠机具有用于沿着大致水平的路径以预定的方式将预定方向连续地推进到彼此的传送装置。 后缘文件夹具有安装在路径下方并横向于路径的可旋转轴。 轴已经安装在其上用于旋转，其中一个或多个臂从轴的轴线向外延伸。 折叠头从臂的远端延伸。 控制装置具有一个传感器，该传感器产生一个后沿信号，该后沿信号指示沿着该文件夹的上游路径的第一位置的空白的后缘的离开。 在后缘信号之后确定的间隔结束时，轴沿纸箱行进的方向旋转，使得轴上的头部与坯料的后面板接触，并将其折叠大约180度 。 轴停止在那里，直到纸板面板从头部的行进路径的下面和外部滑出。 然后将轴进一步旋转到路径下方的停留位置，并在那一点停止，直到感觉到下一个空白。 可以针对不同的机器速度和不同尺寸的纸箱来调节控制装置。 还提供了用于监视操作，进行调整以及检测和诊断故障的电路。

摘要： A trailing panel folding system for use in a blank folding machine. The system includes a rotatable shaft mounted below the pass path of the blanks and transverse thereto. A motor is connected to drive this shaft and an arm assembly is mounted on the shaft and includes an arm extending away from the shaft and a folding head for folding a trailing panel of a blank. An encoder is interconnected with the drive means to provide a pulsed output related to the velocity at which the blanks are moving along the path, and a blank sensor provides a trailing edge signal when the trailing edge of the sensed blank leaves the location. A programmable motor controller moves the arm assembly to a predetermined start position in which the folding head is disposed upstream of the shaft, causes the folding head to move to an up position wherein it overlies the folded trailing panel at a speed sufficiently fast to overtake and fold the panel, causes the folding head to dwell in the up position, and causes the arm means to move to a start position after the folded panel has moved from under the folding head. A method of folding a trailing panel of a carton blank is also disclosed.
