摘要： A pivotal feed head for feeding non-rigid paper sheets individually from a feed hopper to a photo-optical utilization station at high speed without interruption, overlap or collision between sheets including oppositely disposed members for applying a normal force between an enlarged resilient tired feed wheel adapted for unidirectional rotation and a conjointly movable, engageable retard roller. The feed head is mounted for pivotal movement about an outboard drive member. A frictional brake for the retard roller is adjustable to provide a preset load at the nip between the feed wheel and the retard roller while a solenoid-actuated one-way clutch operably engages the feed wheel mounting shaft for incremental signal controlled paper feed. A vertical, signal-controlled latching member locks the feed head in a vertical pivoted position at the end of the vertical upward movement of the paper stack platform as the paper is fed into the nip between the feed wheel and the retard roller.
摘要翻译： 一种用于将非刚性纸片从进料斗单独地供给到光学光学利用站的枢转进给头，不间断地，不间断地包括在相对设置的构件之间的重叠或碰撞，用于在扩大的弹性疲劳进料轮 适用于单向旋转和可联动的可接合延迟辊。 进给头安装成围绕舷外驱动构件枢转运动。 用于延迟辊的摩擦制动器是可调节的，以在进给轮和延迟辊之间的辊隙处提供预设的载荷，而电磁致动单向离合器可操作地接合进给轮安装轴用于增量信号控制的进纸。 垂直的，信号控制的闩锁构件在进纸轮和延迟辊之间的辊隙中将进给头锁定在纸堆平台的垂直向上运动的端部的垂直枢转位置。

摘要： A sheet item reloader-feeder wherein a pivoted item receiving tray is arcuately-angularly movable from a load position in which the tray is empty to a feed position in which the tray is full. A coiled spring biases the item tray vertically to bring the top most sheet item into the nip of a feeding device. A cable connected to the tray is interconnected to an over-center spring biased cam and an external tray handle whereby movement of the handle causes the tray to automatically move against the tension of the biasing spring from the empty position to the loaded position bring the top most sheet item into the nip of the feeding device for automatic feeding. Two such reloader-feeder devices are stacked in vertical offset relation to one another permitting operator reloading during feeding without stopping the operation of the apparatus.
