Automated Document Inserter (ADI)s are machines designed to rapidly insert documents such as statements, letters and ads into envelopes for mass mailings. By automating this document insertion process, businesses are able to achieve significant productivity increases and cost savings over manual document insertion.
How Automated Document Inserter (ADI)s Work
Automated Document Inserter (ADI) operate via a series of programmed steps to automatically load documents, fold them as needed, insert them into envelopes and seal the envelopes for mailing. At the core of the machine is a multi-pocket document feeder that can hold a variety of pre-printed documents. The feeder uses timing belts and rollers to precisely feed documents one at a time into the inserter area.
Meanwhile, the machine's envelope feeder provides a continuous supply of envelopes onto which the documents will be inserted. Sophisticated sensors and controls inside the machine coordinate the sequencing and timing of document and envelope feeds. When a document reaches the insert zone, precise gates and rollers guide it into the waiting envelope which is held in place. For multi-page documents, the inserter will fold pages as necessary before insertion.
Once the document is fully inserted, a sealer applies glue or moisture to precisely seal the envelope flaps. Completed envelopes are then ejected from the machine onto a conveyor or collection bin for further processing or mailing. High-volume inserters can process thousands of documents per hour. Programmable job settings allow the machine to run a variety of document types and sizes without operator adjustments between jobs.
Advantages of Automated Document Inserter (ADI)s
The primary advantages of Automated Document Inserter (ADI) Industry are gains in productivity and reductions in labor costs compared to manual document insertion methods. Some key benefits include:
Higher Speeds - Automated inserters can process mailings at speeds hundreds of times faster than manual methods. Large machines can insert thousands of documents per hour. This allows exponentially higher volumes of mailings to be completed in less time.
Consistent Quality - With automated processes, every document is inserted using the precise same motions and timing. This ensures consistent folding, positioning and sealing in every envelope compared to potential human errors in manual insertion.
Reduced Labor - Automated inserters require just one operator versus large teams needed for manual insertion. This shrinks the number of employees and payroll hours required to complete mailings. It also helps avoid lost productivity from sick/vacation days.
Error-Proof Jobs - Integrated quality control systems in advanced inserters detect incomplete, incorrect or missing inserts to prevent faulty mailings from being sent. Operators are alerted to reprocess problem addresses.
Cost Savings - With higher volumes, consistent quality and lower labor overhead, businesses gain significant per-piece cost reductions for their mailings versus manual insertion costs. Automation delivers a strong long-term ROI.
Flexibility - Programmable job settings make inserters very versatile. They can seamlessly transition between different sized documents and batches of mixed media without time-consuming manual adjustments between jobs.
Automatic Ancillary Tasks - More sophisticated inserters come equipped with abilities like document bursting, folding, collating and tabbing to further streamline ancillary tasks involved in document processing and mailing creation.
Document Size Compatibility
While high-volume inserters are engineered to work most efficiently with standard size paper documents, most modern inserters support a range of input document sizes through adjustable features:
Length - Most common document lengths range from 5 to 15 inches but many inserters can accommodate sheets up to 17-20 inches long through adjustable fold plates and belts.
Width - Common widths range between 3.5 to 9 inches but many machines support media from 3 to 11 inches wide using adjustable feeder pockets and gates. Narrower/wider documents may require special inserts.
Thickness - Thickness tolerance ranges from single sheet paper up to approximately 1/8 inch thick cardstock. Thicker media risks jamming moving parts if used.
Paper Stock - Most machines work reliably with standard 20-24lb office paper as well as glossy and cardstock media. However, extra-smooth glossy or textured stock risks minor feeding issues.
Overall size tolerance gives inserters flexibility but physical size limits still apply based on envelope/document size combinations. Operators load matched job settings for best performance.
Enhanced Productivity Applications
Advanced inserters provide even greater gains in throughput and efficiency for organizations handling especially large or complex mailings:
Multi-pass systems orchestrate simultaneous feeding, insertion and sealing on multiple parallel processing lanes to double, triple or quadruple overall production rates.
Continuous feed options maintain steady throughput by eliminating stopping/starting across pagination boundaries. They pull web-fed documents in an uninterrupted stream.
Serialization and variable data features add recipient specific details like barcodes, addresses or promotions pulled from external databases.
In-line finishing expands inserters with integrated tasks like folding, inserting, sealing plus stamping, wrinkle-free inserting and shrink wrapping for finished mail-ready packets in one pass.
Robotic arms and multi-station, pallet-based designs integrate inserters into fully automated and lights-out production cells suited for industrial processing volumes. Advanced tracking, reporting and integration with upstream/downstream equipment enhances process visibility and control.
As front-end automated document processing technologies evolve, inserters will advance to handle much higher volumes through innovative speed, workflow and material handling enhancements. With demonstrable cost benefits, inserters empower more organizations to migrate time-intensive manual mail production processes
