Pneumatic post receiving station - uses magnetic valve operated by transport cylinder to interrupt drive air flow from blower

摘要

The pneumatic post receiving station holds a pneumatic post transport cylinder which arrives in the pressure operation ready for removal in a give n position. There is a device operated by the cylinder to interrupt the drive air flow from a continuous blower such that further cylinders which are on the way to the station remain in the tube system in front of the station without drive. After removal the first cylinder is conveyed on by removing the interruption to drive air flow. The air flow interrupter consists of an electrically controlled magnetic valve closing by-pass air orifice, which allows the drive air to flow outwards from the transport tube or the blower connection air tube or interrupts or short circuits the drive air flow of the blower.
