    • A self-adaptive stacker (30) comprised of infeed and stacking sections (100;200) whose movement is coordinated to provide interception of the signature stream (34). The infeed conveyor section (100) "Vees" the incoming signature stream (34) through the use of rollers (40,42) of different diameters mounted upon straight, spaced, parallel shafts. A microprocessor (400) utilizes a signal, representative of the infeed conveyor speed, together with a signal from a signature counter (164), to track the movement of each signature and thereby its arrival at the intercept position. Low armature inertia motors (172) drive the three axes, (stacking section (200), the turntable (302) and the ejectors (303,304) to provide rapid starting, acceleration, deceleration, and stopping at selected positions. These motors are controlled to interact in real-time in order to adapt the three axes to the rate of the incoming signatures (34). The movement of the signature carriers (220) is altered, when necessary, due to speed changes of the signature stream. A sensor located at the intercept ready position detects the passage of a signature carrier (220) to initiate acceleration of the signature carrier (220) by an amount which is a function principally of signature thickness, velocity and separation distance to control the amount of acceleration required to move the carrier (220) beneath the first signature of the next stack to be formed. The load current of the stacker motor (208) is monitored to detect the occurrence of a jam which condition is prevented from damaging the stacker section conveying assembly by halting and then reversing the stacker section motor (208) during a predetermined short time interval. Chain tension springs (212) allow the chain to yield for a period sufficiently long to permit the motor (208) to be halted and reversed before the stacking section (200) (i.e., drive chains, sprockets, etc.) can be damaged. A turntable section (300) forms compensated bundles by rotating a platform (302). A pusher assembly is mounted beneath the rotatable turntable platform (302) and includes pusher bars arranged by linkage members (346-349) to move precisely along the path of the drive chain to enhance monitoring, control and movement of the push rods (303,304). A sensor senses the passage of a push rod (303) to detect the initial movement and subsequent thereto the arrival of a push rod (303) to the home position.
    • 一种自适应堆叠器（30），包括进给和堆叠部分（100; 200），其移动被协调以提供签名流（34）的截取。 进料输送机部分（100）通过使用安装在直的，间隔开的平行的轴上的不同直径的滚子（40,42）“Vees”进入的签名流（34）。 微处理器（400）利用代表进给输送机速度的信号以及来自签名计数器（164）的信号来跟踪每个签名的移动，从而其到达拦截位置。 低电枢惯性电动机（172）驱动三个轴（堆叠部分（200）），转台（302）和喷射器（303,304），以在选定位置提供快速启动，加速，减速和停止，这些电机被控制为 实时交互以使三轴适应输入签名的速率（34），由于签名流的速度变化，签名载体（220）的移动在必要时被改变，传感器位于 在拦截就绪位置检测签名载体（220）的通过以启动签名载体（220）的加速度，其主要是签名厚度，速度和间隔距离的函数，以控制移动所需的加速量 在下一个堆叠的第一个签名之下的载体（220）将被形成，监视堆垛马达（208）的负载电流，以检测堵塞的发生，防止这种情况损坏stac 通过在预定的短时间间隔期间停止然后使堆垛部分马达（208）反转，从而产生切割部输送组件。 链条拉伸弹簧（212）允许链条产生足够长的时间，以便在堆叠部分（200）（即，驱动链条，链轮等）可能被损坏之前允许马达（208）停止和反转。 旋转台（300）通过旋转平台（302）形成补偿束。 推动器组件安装在可旋转转盘平台（302）的下面，并包括由连杆构件（346-349）布置的推杆，以沿着驱动链的路径精确移动，以增强推杆（303,304）的监控，控制和移动， 。 传感器感测推杆（303）的通过以检测初始运动，随后检测推杆（303）到达原始位置。

    • @ Apparatus and method for accumulating generally flat articles of substantially the same size and shape into stacks of specific count. The apparatus comprises at least one vertically oriented spiral member having an exterior leading edge and an interior trailing edge. A prime mover rotates the spiral member about its horizontal axis of rotation. A product stack-building area is provided through which the leading and trailing edges of the spiral member passes once each revolution thereof. An infeed device feeds products at substantially the same elevation to the top of the stackbuild- ing area and onto the outer surface of the spiral member constituting a product support surface which recedes from the article infeed elevation at a predetermined rate. At least one side plate is provided to keep the products within the stack-building area. An outfeed device to receive stacked products passes through the spiral member at an elevation just below the trailing edge thereof. Products are fed to the top of the stack-building area. The spiral element is rotated through the stack-building area, and as its leading edge passes therethrough, a new product stack is started thereon and is segregated from the previous stack accumulated on the spiral member. The previous accumulated stack is deposited on the outfeed device by the trailing edge of the spiral member.
