    • An envelope feeder (200) for removing envelopes from an envelope stack. The envelope feeder comprises a shuttle plate (150) and a suction cup assembly. The shuttle plate (150) translates between a position under the envelope stack and another position partially remote from the envelope stack. The shuttle plate (150) includes an orifice (240) passing through its surface (252) and an envelope gripping mechanism (180) in connection with a vacuum valve (256). The suction cup assembly has a suction cup (230) connected to a hollow rod (233) that is in connection with another vacuum valve (238). An actuator (236) engages the suction cup (230) and moves the suction cup between an extended position and a retracted position. The suction cup (230) attaches to an envelope at the bottom of the envelope stack when it is in the extended position, and pulls the envelope toward the shuttle plate (150) as it moves to the retracted position. Then the envelope gripping mechanism (180) retains the envelope, allowing the shuttle plate to remove the envelope from the envelope stack.
    • 用于从信封叠层移除信封的信封馈送器(200)。 信封进料器包括梭板(150)和吸盘组件。 梭板(150)在信封堆叠下的位置和部分远离信封叠层的另一位置之间平移。 梭板(150)包括通过其表面(252)的孔口(240)和与真空阀(256)相关联的封套夹持机构(180)。 吸盘组件具有连接到与另一个真空阀(238)连接的中空杆(233)的吸盘(230)。 致动器(236)接合吸盘(230)并且使吸盘在延伸位置和缩回位置之间移动。 当吸入杯处于伸展位置时,吸盘(230)附接到信封堆叠底部的封套,并且当其移动到缩回位置时,吸盘(215)将其拉向往复板(150)。 然后,信封夹持机构(180)保持外壳,允许梭板从信封叠层移除信封。
