    • A sheet withdrawing mechanism is disclosed for a collator having a plurality of spaced moving shelves or partitions forming pockets. Each partition or pocket receives a pile of sheets and as each pocket passes sheet withdrawing position, rotating spiders, preferably having a plurality of arms, each extend an arm into each pocket in succession, engage the top sheet of the pile and at least partially withdraw the sheet far enough to be reached by adjacent secondary withdrawing mechanism which completes the withdrawal of the sheet from the pocket. Two constructions of spiders are illustrated and described, one having relatively long arms for partition spacing having a relatively large dimension so that the arc of movement of the end of each arm is great enough to withdraw the sheet sufficiently solely by the sweep of the arm. The second spider construction is for partition spacing having a relatively lesser dimension so that a greater number of pockets can be provided in an over-all dimension. This second spider has relatively shorter arms and has a withdrawal roll on the end of each arm which is rotated so that each sheet is partially withdrawn from its pocket by a combination of the sweep of the arm and the rotation of the withdrawal roll. Also included is mechanism to advance the phase of the spider arms with respect to the phase of the pockets as they rotate. Thus, the spider arms are advanced and enter the pockets progressively sooner.
    • 公开了一种用于具有多个间隔开的移动搁架或形成口袋的间隔件的整理机的片材抽出机构。 每个分隔件或口袋都接收一堆纸张,并且当每个袋子通过纸张退出位置时,旋转的蜘蛛,优选地具有多个臂,各自将臂连续地延伸到每个口袋中,与桩的顶片接合并且至少部分地退出 片材远远足以通过相邻的次级抽出机构到达,从而使片材从口袋中取出。 示出和描述了两个蜘蛛构造,一个具有相对长的用于分隔间隔的臂具有相对大的尺寸,使得每个臂的端部的移动弧足够大以仅通过臂的扫掠而足够地抽出片材。 第二个蜘蛛结构用于具有相对较小尺寸的分隔间隔,使得可以在整个尺寸上提供更多数量的凹穴。 这个第二个蜘蛛具有相对较短的臂,并且在每个臂的端部上具有撤回辊,该抽出辊被旋转,使得每个片材通过臂的扫掠和取出辊的旋转的组合部分地从其口袋中撤出。 还包括当它们旋转时相对于袋的相位推进蜘蛛臂相位的机构。 因此,蜘蛛臂先进,逐渐进入口袋。

    • A rotary collator is disclosed having a rotary drum with a plurality of radially extending partitions forming radially extending pockets against which partitions the sheets to be collated are held by clamping means. The clamping means for each pocket has operating means which opens or releases the sheet clamp prior to the position of the pocket where a sheet is to be ejected from the pocket. The clamp operating means closes the clamping means after the pocket has passed sheet ejecting position. The operating means uses a toggle structure and a relatively heavy compression spring to hold the sheets in the pile against the partition when in clamping position. This spring is operating mostly under relatively light tension so that its flexing is reduced considerably thereby and the likelihood of breaking is much reduced. Also breaking of a compression spring is much less likely because pressure is applied by flat ends of the spring abutting the parts engaged.
    • 公开了一种具有旋转滚筒的旋转滚筒,该旋转滚筒具有形成径向延伸的凹穴的多个径向延伸的隔板,夹紧装置将待分页的片材分隔。 每个口袋的夹持装置具有操作装置,该操作装置在纸张将要从口袋中排出的口袋的位置之前打开或释放纸张夹具。 夹具操作装置在袋已通过纸张排出位置之后关闭夹紧装置。 操作装置使用肘节结构和相对较重的压缩弹簧以在夹紧位置时将片材保持在隔离件中。 这个弹簧主要是在相对较轻的张力下运行,因此它的弯曲度显着降低,从而大大降低了断裂的可能性。 压缩弹簧的破坏也不太可能,因为弹簧的平坦端部抵靠接合的部件施加压力。
