7102095
The invention relates to co-mailing a first and a second mail stream of products, and more particularly, to co-mailing a first mail stream of wrapped products and a second mail stream of unwrapped products.
Costs associated with the U.S. Postal Service are climbing. Publishers and printers are continually looking for ways to reduce postage costs.
The invention includes the co-mailing of a first mail stream of wrapped products with a second mail stream of unwrapped products according to a predetermined sequence.
The invention particularly includes a process to combine wrapped and unwrapped products into one mail stream including generating a master mailing list of products having a predetermined sequence, generating a first mail stream, wrapping all of the products in the first mail stream, generating a second mail stream of unwrapped products, and combining the first stream of wrapped products and the second mail stream of unwrapped products into a single mail stream according to the predetermined sequence.
Further, the invention includes a co-mailing line including a first path which generates a first mail stream of wrapped products, the first path including at least one feeder for delivering unwrapped products to a conveyor, a wrapper for wrapping the products, and an accumulator for storing the wrapped products, a second path which generates a second mail stream of unwrapped products, the second path including at least one feeder for delivering unwrapped products to a conveyor, a controller having inputted a master mailing list of products, a combination area wherein the wrapped products of the first mailing stream exiting the accumulator are combined with the unwrapped products of the second mail stream in a sequence as determined by the controller to produce a third mail stream, and a third path for the conveying the third mail stream for further processing.
Other features and advantages of the invention will become apparent to those of ordinary skill in the art upon review of the following drawing and detailed description.
Before the invention is explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.
Referring now to
More specifically, the first mail stream of products 10 preferably is a stream of printed products that are wrapped. In addition to being wrapped, individual products may include components that are insertable into an envelope, with the envelope being wrapped along with the product. The components can include pieces printed inline or offline or not printed at all such as CD-ROM's, or other electronic media. As an example, the component could be a personalized subscriber invoice laser printed off-line and fed to a gathering chain or conveyor 16 on path A via a feeder 18. This first component preferably would include thereon a code such as a bar code, human readable numbers or some type of printed indicia with such code being used to communicate to a controller 20 a sequence number on the component such that a correct product will be matched with the component before wrapping. The sequence number on the first component is read and communicated to the controller 20. The controller 20 then controls feeders 22 that selectively feed other components or inserts onto the gathering chain 16. The first component is therefore matched with the selectively fed subsequent components. The first and subsequent components are then inserted into an envelope by an envelope inserter 24. Preferably, there is more than one feeder 26 of envelopes. The controller 20 controls which envelope type is feed to the gathering chain 16 for insertion of all components.
The envelope containing the one or more components continues on the gathering chain 16 to the feeders 28. The feeders 28 selectively feed unwrapped products onto the gathering chain 16 as controlled by the controller 20. Each product fed to the gathering chain 16 therefore matches up with any associated envelope and its contents. The envelope and matched product continue down the gathering chain 16 and are wrapped together by a conventional wrapper 30. The wrapper material may be paper or poly or any other suitable material. The wrapped products then enter an accumulator 32 where they are stored until they are fed on demand as is described next.
Turning now to the second mail stream 12, products that have not and will not be wrapped are fed from hoppers 34 onto a gathering chain 36 to form path B. The products are then conveyed to station or combination area C. At station C, the first mail stream 10 and the second mail stream 12 are combined to form a single or third mail stream 14 in a predetermined order. That predetermined order is derived from a master sequence or master mailing list know to the controller 20. For example, the sequence can be in zip code or other address-related order. The controller 20 commands the hoppers 34 to begin feeding products in sequence to the gathering chain 36. The stream however is designed to have gaps or holes in it through the sequence as controlled by the controller 20.
The wrapped products from the first stream 10 are fed on demand from the accumulator 32 into the appropriate gaps as controlled by the controller 20 to produce a combined stream of products in the predetermined sequence of the master list. With the use of the accumulator 32, if there is a problem with the feeders 22 or 26 upstream, the process of combining the first and second mail streams 10 and 12 can continue as long as there is product in the accumulator 32, giving an operator time to fix any upstream problem before the whole co-mailing line has to be stopped for maintenance.
After the first and second mail streams 10 and 12 are combined at the station C, the combined or third mail stream 14 is conveyed to an optional ink jet area 38 where address or other indicia can be selectively printed on the products and then conveyed to a conventional stacker 40 for further conventional processing.
The titles of the products of the first and second mail stream can be different, and similarly, the titles within a mail stream, first or second, can be different. The products can include magazines, books, brochures, direct mail pieces, other printed products and the like.
