    • A stacking device for forming stacks of articles of predetermined count, using a stacking wheel having a multiplicty of uniformly spaced peripheral slots. The slots are adapted to receive articles sequentially at a loading station and carry them to an unloading station having a plurality of stacking sites. The slots are divided into two or more sets, the slots in each set being equal to number to the predetermined count and adapted to deliver the articles therein to the unloading station with the leading edges of the articles at a predetermined radial offset from the axis of the stacking wheel. Each set of slots is associated with the stacking of articles at a specific stacking site and the slots of a set associated with one stacking site provide a different radial offset than those of a set associated with another stacking site. The stacking sites are arranged, in the downstream direction, in order of diminishing radial offset of their associated sets of slots. Separation of the stacks is effected by having stripping fingers for each stacking site act at the appropriate radial offset.
    • 一种堆叠装置,用于使用具有均匀间隔的外围槽的多个的堆叠轮来形成预定计数的物品堆叠。 槽适于在装载站处顺序地接收物品并将其运送到具有多个堆垛位置的卸载站。 槽被分成两组或多组,每组中的槽等于预定计数的数量,并且适于将物品输送到卸载站,其中物品的前缘处于从 堆叠轮。 每组插槽与在特定堆垛位置处的物品的堆叠相关联,并且与一个堆垛位置相关联的一组的槽提供与与另一个堆垛位置相关联的集合不同的径向偏移。 堆叠位置沿下游方向按照其相关的槽组的径向偏移减小的顺序排列。 堆叠的分离是通过使每个堆叠位置的剥离指针以适当的径向偏移来起作用的。

    • Apparatus for cutting patterns from successive contiguous segments of an elongated layup of sheet material has a zoned vacuum table which includes an endless bristle mat conveyor, for shifting a layup along the table to position a segment of the layup in the cutting zone of the table and for holding the layup segment in the cutting zone, and a carriage assembly, which moves a cutting mechanism relative to the table and in cutting engagement with the segment to cut patterns from the segment in response to signals from a programmable controller. A rotary encoder mounted on the carriage assembly has a pinion which engages a rack carried by the conveyor to detect movement of the carriage assembly relative to the conveyor when the carriage assembly returns to its starting position after completing its cutting cycle. A responsive circuit connects the encoder to the conveyor drive motor and energizes the drive motor in response to the relative movement detected by the encoder to cause the conveyor to move the layup in the return direction and through a distance equal to the distance traversed by the carriage assembly in returning to its starting position whereby the next successive segment of the layup is accurately positioned in the cutting zone. An error sensing circuit detects the magnitude and direction of an error in positioning the layup and alters the data in the controller to nullify the error. A vacuum device cleans the bristle mat while the conveyor is in motion and also reduces the vacuum holddown force applied to the layup while it is being shifted by the conveyor.
    • 用于从片材的细长叠层的连续连续段切割图案的设备具有分区真空台,其包括无端刷毛垫输送器,用于沿着桌子移动叠层以将叠层的一段定位在工作台的切割区域中, 用于将切割区域保持在切割区域中;以及滑架组件,该滑架组件使切割机构相对于工作台移动并且与切割部分切割啮合,以响应于来自可编程控制器的信号从该切片切割图案。 安装在托架组件上的旋转编码器具有小齿轮,该小齿轮接合由输送机承载的齿条,以在托架组件在完成其切割循环之后返回到其起始位置时检测托架组件相对于输送机的运动。 响应电路将编码器连接到输送机驱动马达,并响应于由编码器检测到的相对运动而激励驱动马达,以使输送机在返回方向上移动叠层并且通过等于由托架穿过的距离的距离 组件返回到其起始位置,由此下一个连续的铺层段准确地定位在切割区域中。 误差检测电路检测定位叠层误差的大小和方向,并改变控制器中的数据以消除误差。 当输送机运动时,真空装置清洁刷毛垫,并且还减小了施加到铺层的真空压紧力,同时它被输送机移动。
