Abstract
This invention relates to a document collating and envelope stuffing apparatus having a continuous conveying mechanism that collects and collates documents from feeding stations and conveys the collated documents to an envelope stuffing station in a continuous manner. The feeding stations have platforms associated therewith where the documents are deposited so as to be picked up by the conveying mechanism and subsequently stuffed into envelopes. Downstream from the stuffing station is another conveying mechanism that conveys the stuffed envelopes to sealing and postage metering devices.
Claims19
A document collating and envelope stuffing apparatus wherein documents are collated in seriatim along a longitudinally extending feed path having an upstream end and a downstream end and then collectively stuffed into an envelope, comprising:
- a plurality of platforms arranged in series along the feed path;
- means for feeding documents to said platforms;
- a stuffing station located on the feed path downstream from said platform, said stuffing station having means for releasably detaining an envelope at a location on the feed path and means for opening the throat of an envelope that is being detained by said detaining means;
- means for feeding envelopes to said detaining means;
- a continuous conveying means extending along the feed path, said conveying means having two sets of longitudinally spaced pushers, said sets being spaced laterally to each other said platforms and said stuffing station being located intermediate said two sets of pushers, and said throat opening means and said detaining means being in the path of at least one of said sets of pushers;
- whereby,
- said pushers are conveyed along said feed path from the upstream end to the downstream end of the feed path, past said platforms and said stuffing station by said conveying means to collect documents placed upon said platforms, to insert collected documents into an envelope located at said detaining means, and to release said detaining means.
A document collating and envelope stuffing apparatus comprising:
- a plurality of platforms arranged in series along a longitudinally extending feed path;
- means for feeding documents to said platforms;
- a pair of laterally opposed endless chain conveyors disposed below and on opposite sides of said platforms, each chain conveyor having at least one pusher secured thereto that extends normally therefrom and is laterally aligned with a pusher on the opposed chain conveyor;
- means for continuously driving said endless chain conveyors, said pushers being located along said feed path so as to be conveyed immediately adjacent the lateral ends of said platforms when said chain conveyor is being driven from an upstream end to a downstream end whereby sheets disposed on said platforms are collected by said pushers and collated along said feed path as said endless chains are being driven;
- a stuffing station having means for releasably detaining envelopes and envelope throat opening means located downstream from said platforms;
- means for supplying envelopes to said detaining means of said stuffing station,
- a second pair of laterally opposed longitudinally extending endless chain conveyors located along said feed path downstream from said first pair of endless chain conveyor and below said stuffing station, said second pair of endless chain conveyors each having at least one pusher attached thereto, a pusher on one said second chain conveyors being laterally aligned with a pusher on said opposed second chain conveyor;
- and
- means for continuously driving said second endless chain.
A document collating and envelope stuffing apparatus wherein documents are collated in seriatim along a longitudinally extending feed path having an upstream end and a downstream end and then collectively stuffed into an envelope, comprising:
- a plurality of platforms arranged in series along the feed path;
- means for feeding documents to said platforms;
- a stuffing station located on the feed path downstream from said platforms, said stuffing station having means for releasably detaining an envelope at a location on the feed path and means for opening the throat of an envelope that is being detained by said detaining means;
- means for feeding envelopes to said stuffing station;
- a continuous conveying means extending along the feed path, said conveying means having two sets of longitudinally spaced pushers, a pusher of one of said sets being laterally aligned with a pusher of the other set, said platforms and said stuffing station being located intermediate said two sets of pushers;
- means coupled to said conveying means for activating said throat opening means;
- whereby,
- said pushers are conveyed from the upstream end to the downstream end past said platforms and said stuffing station by said conveying means to push documents on said platform onto said feed path, to insert documents into an envelope located at said detaining means, and to release said retaining means.
A document collating and envelope stuffing apparatus wherein documents are collated in seriatim along a longitudinally extending feed path having an upstream end and a downstream end and then collectively stuffed into an envelope, comprising:
- a plurality of platforms arranged in series along the feed path;
- means for feeding documents to said platforms;
- a stuffing station located on the feed path downstream from said platforms, said stuffing station having means for releasably detaining an envelope at a location on the feed path and means for opening the throat of an envelope that is being retained by said detaining means;
- means for feeding documents to said stuffing station;
- a continuous conveying means extending along the feed path, said conveying means having two sets of longitudinally spaced pushers, a pusher of one of said sets being laterally aligned with a pusher of the other set, said platforms and said stuffing station being located intermediate said two sets of pushers;
- means for driving said continuous conveying means;
- whereby,
- said pushers are conveyed from the upstream end to the downstream end of the feed path past said platforms and said stuffing station by said conveying means to collect documents on said platforms and collate the same to insert the collated documents into an envelope located at said detaining means, and to release said detaining means.
A document collating and envelope stuffing apparatus wherein documents are collated in seriatim along a longitudinally extending feed path and then collectively stuffed into an envelope, comprising:
- a plurality of platforms arranged in series along the feed path, each of said platforms having a lateral dimension less than the length of the documents to be conveyed;
- means for feeding documents individually to each of said platforms;
- a stuffing station located on the feed path at one end of the series of said platforms, said stuffing station having means for releaseably detaining an envelope at a location on the feed path and means for opening the throat of an envelope that is being detained by said detaining means;
- means for feeding envelopes to said detaining means;
- conveying means extending along the feed path, to define an upstream end and a downstream end;
- said conveying means having two sets of laterally spaced pushers, the pushers of each set being longitudinally spaced from one another, a pusher of one of said sets being laterally aligned with a pusher of the other set;
- said platforms and said stuffing station being located intermediate said two sets of pushers, and said throat opening means and said detaining means being in the path of at least one of said sets of pushers;
- means for driving said conveying means;
- whereby,
- said pushers are conveyed along said feed path past said platforms and said stuffing station to deliver documents to the feed path, to collate the documents that are delivered to the feed path to insert collated documents into an envelope detained by said detaining means, and to release said detaining means.
