Abstract:
A feeding module for use in an envelope inserting machine. The feeding module comprises a mounting support fixedly mounted on the chassis of the machine, and a sheet feeder releasably mounted on the mounting support, wherein the sheet feeder comprises a tray for supporting a stack of the sheets and a retrieving mechanism for retrieving one sheet at a time from the bottom of the stack. The retrieved sheet is guided through a curved channel to the moving belt of the inserting machine. The channel is formed by two curved panels, one of which can be lifted away from the other for jam clearance.
Abstract:
A method and apparatus for reducing burden in retrieving sheets of material from the bottom of a substantially vertical stack of sheets in a sheet feeder. The apparatus comprises a first convex surface at the bottom half of the stack protruding into one side of the stack for pushing the sheets toward the other side, and a second convex surface on the second side below the first convex surface for pushing the sheets toward the first side. The first and second convex surfaces each provide a counteracting force resisting the downward movement of the stack, and these countering forces have upward vertical components partially countering the downward vertical force due to the weight of the stack.
Abstract:
A method and system for transporting envelopes from an envelope feeder to an envelope staging area in an envelope insertion machine. The envelope transport system includes two envelope bins and two envelope supply paths linking the envelope bins to an envelope feeder. Each of the bins is used to temporarily store an envelope before that envelope is moved to the staging area. The envelope supply paths are controlled by a flipper gate which alternately opens one path and closes another so as to allow an envelope to enter one envelope bin while another envelope in the other envelope bin is moved to the staging area. With the dual envelope bins connected to the dual supply paths to receive envelopes released by the envelope feeder, the envelope feeder does not have to slow down substantially in order to wait for the released envelope to clear the feeding path.
