    • A printing system includes a marking engine for applying a marking substance onto a sheet and a sheet conveying device. The sheet conveying device includes a belt arranged to carry sheets from an upstream end to a downstream end of a transport path, the belt having an array of perforations; an array of suction nozzles arranged below the belt for sucking-in ambient air through the perforations of the belt; and at least one blow nozzle arranged at the downstream end of the transport path for blowing out a gas through the perforations of the belt. The conveying device further includes an array of anti-friction blow nozzles interleaved with the array of suction nozzles and connected to a blower for blowing-out a gas towards the bottom surface of the belt during the traverse of the sheet along the marking engine.

    • An apparatus is provided for decelerating sheets which are to be placed on a stack. The apparatus comprises rotatably driven clamping elements, which are provided with clamping zones that intermittently reach to the feeding plane of the sheet when revolving. The apparatus further includes a mating element which is rotationally disposed on the opposite side of the conveying plane of the sheets such that a sheet can be clamped between the clamping zones and the mating element. The clamping elements are connected to an asymmetrical rotary drive unit while being equipped with ring segment-shaped clamping zones on a section of the circumference thereof. A deflecting device is also provided which deflects the rear edges of the sheet from the feeding plane in a downward direction arranged at a distance from and upstream of the clamping elements in the direction of travel of the sheets.
    • 提供一种用于减速要放置在堆叠上的片材的装置。 该装置包括可旋转地驱动的夹紧元件,其设置有当旋转时间歇地到达片材的馈送平面的夹紧区域。 该装置还包括配合元件,该配合元件旋转地设置在片材的输送平面的相对侧上,使得片材可夹持在夹持区域和配合元件之间。 夹紧元件连接到不对称的旋转驱动单元,同时在其圆周的一部分上配备环形段形夹持区域。 还提供了一种偏转装置,其使得片材的后边缘沿着沿着片材的行进方向布置在夹紧元件一定距离和上游的向下方向上从馈送平面偏转。

    • There is described an inspection system (10) for inspecting the quality of printed sheets which are transported by a sheet conveyor system comprising at least one sheet gripper system (3a, 3b) including a plurality of spaced-apart gripper bars (32) for holding the printed sheets by a leading edge thereof. The inspection system (10) comprises an optical quality control apparatus for carrying out inspection of a first side of the printed sheets while the printed sheets are being transported by the sheet gripper system (3b). The optical quality control apparatus includes a line camera (11) for scanning the first side of the printed sheets at an inspection location which is situated at a location proximate to a portion of the sheet gripper system (3b) where the gripper bars (32) transporting the printed sheets undergo a change of direction of displacement while the printed sheets are still being scanned by the line camera (11). The inspection system (10) further comprises a suction roller (50) that is placed in front of the optical path (B) of the line camera (11) along the path (A) of the printed sheets being transported by the sheet gripper system (3b), which suction roller (50) contacts a second side of the printed sheets opposite to the first side which is being scanned by the line camera (11), the suction roller (50) being driven at a selected circumferential speed to drive successive portions of the printed sheets being inspected by the quality control apparatus at a determined and controlled speed past the line camera (11).
    • 描述了一种检查系统(10),用于检查由包括至少一个片夹持器系统(3a,3b)的片材输送机系统输送的打印片材的质量,该片材夹持系统包括多个间隔开的夹持杆(32),用于保持 印刷的纸张由其前缘。 检查系统(10)包括光学质量控制装置,用于在通过纸张夹持系统(3b)传送印刷的纸张的同时,对打印的纸张的第一面进行检查。 光学质量控制装置包括线摄像机(11),用于在位于靠近纸张夹持器系统(3b)的一部分的位置处的检查位置扫描打印的纸张的第一侧,其中夹持杆(32) 当印刷的纸张仍被行式相机(11)扫描时,传送打印的纸张经历位移方向的改变。 检查系统(10)还包括一个吸引辊(50),该抽吸辊(50)沿着由纸张夹持系统传送的打印纸张的路径(A)放置在行式相机(11)的光路(B)的前面 (3b),所述吸辊(50)接触与由所述线摄像机(11)扫描的所述第一侧相反的所述打印片材的第二侧,所述吸辊(50)以选定的圆周速度驱动以驱动 打印纸的连续部分被质量控制装置以确定的和受控的速度通过线摄像机(11)进行检查。
