    • A transport system for conveying sheet material along a feed path. The transport system includes an electro-dynamic propulsion system for moving sheet material, or a stacked collation of sheet material, along a support deck which defines the feed path. More specifically, the electro-dynamic propulsion system includes at least one guideway and a ferromagnetic element disposed internally of the guideway. The guideway includes a magnetic coil to produce a variable magnetic field. By varying the flux density and polarity of the magnetic field the ferromagnetic element may be propelled within the guideway. An abutment member is coupled to the ferromagnetic element, extends through the elongate opening of the support deck and engages an edge of sheet material. A processor is operative to control the electro-dynamic propulsion system and, accordingly, the rate of travel and position of the sheet material along the feed path.
    • 一种用于沿着馈送路径传送片材的传送系统。 运输系统包括用于移动片材的电动推进系统或者沿着限定进料路径的支撑平台堆叠的片材的堆叠。 更具体地,电动推进系统包括设置在导轨内部的至少一个导轨和铁磁元件。 导轨包括产生可变磁场的磁线圈。 通过改变磁场的磁通密度和极性,铁磁元件可在导轨内被推进。 邻接构件联接到铁磁元件,延伸穿过支撑平台的细长开口并与片材的边缘接合。 处理器可操作以控制电动推进系统,并且因此控制片材沿进给路径的行进速度和位置。

    • A batch sheet feeder has an upstream first conveyor section arranged to convey sheets singly in a downstream direction to a downstream second conveyor section. The second conveyor section has an upper second conveying section and a lower second conveying section forming a gap therebetween. The gap is largest at an upstream end of the second conveyor section and diminishes in size toward a downstream end of the second conveyor section. A gate positioned proximate the downstream end of the second conveyor section selectively blocks sheets fed along the second conveyor section. In another embodiment, the sheet feeder has a sheet conveyor, sheet sensor, and visual attribute sensor. The visual attribute sensor has a field of view covering an area of the conveyor at a certain downstream location so as to sense an area of any sheet on the conveyor at this downstream location. The visual attribute sensor can compare a sensed area of a sheet at the downstream location with a stored visual attribute. In this way, where the sheets of a batch are different, the visual attribute sensor can be used to verify that a sheet of a batch has visual characteristics matching those of the expected sheet at that ordinal position in the batch. This assists in ensuring a batch is not faulty. In a related method of verifying batches of sheets, for each sheet at a given ordinal position in each batch a visual attribute measure for at least an area of the sheet is obtained. A comparison is made of the visual attribute measure with a stored visual attribute measure. Each batch is selectively verified based on this comparison.

    • A plurality of conveying elements is arranged on a traction device of a conveying arrangement in spaced apart succession in a conveying direction. Each conveying element includes a support surface and an end stop coupled to a front of the support surface, positioned perpendicular to the support surface and transverse to the conveying direction. The conveying elements are guided at least while in a feed region of respective feed devices that feed printed sheets to the conveying elements. The support surfaces of the conveying elements are aligned parallel to the conveying direction on the feed section. A holding down device located at a downstream end in the conveying direction of the feed region of each of the feed devices holds down and guides the book block from above while conveyed on the conveying element.
    • 多个输送元件被布置在输送装置的牵引装置上,在传送方向上相继间隔开。 每个输送元件包括支撑表面和连接到支撑表面的前部的端部止挡件,其垂直于支撑表面定位并横向于输送方向。 输送元件至少在各个进料装置的进给区域被引导,这些进料装置将印刷的纸张供给到输送元件。 输送元件的支撑表面平行于进给部分的输送方向排列。 位于每个进给装置的进给区域的输送方向上的下游端的压紧装置在输送元件上传送的同时将书块从上方按压并引导。
