    摘要： An improved envelope opener comprising first, second and third shear stations for shearing three edges of an envelope in sequence one edge at a time. Each shear station sequentially aligns the envelope by contacting the edge to be sheared, shears the contacted edge, and then releases the envelope. Each shear station includes a self-sharpening and self-aligning anvil assembly comprising a pivotable anvil which is spring-urged to an adjustable home position. The home position of the anvil is adjusted by means of a rotatable eccentric stop. During a shearing operation, the anvil is pivoted away from and then back towards the home position. An overly thick envelope will keep the anvil pivoted away from the home position to avoid a jam condition at the shear station. A peel back station downstream of the last shear station peels back the top panel of the envelope to expose the contents thereof. The peel back station comprises a pivotable gate, a support rod, and a pivotable separation roller and an exit roller both of which are pivotable upwardly. The support rod is disposed in proximity to the gate stop, and the gate and rod support an envelope in the station as the envelope panels are first peeled back and then transported through the station. The separation and exit rollers are pivoted upwardly by an overly thick envelope, to enable the envelope to pass through the peel back station without causing a jam condition.

    摘要翻译： 一种改进的信封开启装置，包括用于一次一个边缘剪切信封的三个边缘的第一，第二和第三剪切站。 每个剪切站通过接触要剪切的边缘顺序地对准封套，剪切所接触的边缘，然后释放信封。 每个剪切站包括自磨和自对准砧座组件，其包括可枢转的砧座，该砧座被弹簧推动到可调节的原始位置。 通过可旋转的偏心止动件来调节砧座的原始位置。 在剪切操作期间，砧座枢转离开原位，然后回到原位。 过厚的信封将保持砧座枢转远离原位，以避免在剪切站处的卡纸状况。 最后一个剪切站下游的剥离站将信封的顶板剥离，露出其内容物。 剥离站包括可枢转的门，支撑杆和可枢转的分离辊以及两个可向上枢转的出口辊。 支撑杆设置在门挡板附近，并且门和杆在首先剥离信封面板然后通过工位运送时在支架中支撑一个封套。 分离和出口辊由过厚的外壳向上枢转，以使信封能够通过剥离站，而不会造成堵塞状况。

    摘要： An envelope opener comprising first, second and third shear stations for shearing three edges of an envelope in sequence one edge at a time. Each shear station sequentially aligns the envelope by contacting the edge to be sheared, shears the contacted edge, and then releases the envelope. A microcomputer monitors the advance of the envelope through and between the shear stations and causes the shear stations to cyclically align, shear and release the envelope. A peel back station downstream of the shear station peels back a panel of the envelope to expose the contents thereof. If an envelope is jammed at or between any of the stations, the microcomputer actuates a display to indicate a jam condition. The microcomputer also shuts off power to the opener to prevent damage to the envelope.
