With increasing postal costs and rates, printers and publishers are looking for ways to mail printed products more cost effectively. Combining two or more titles into one mail stream is one way to achieve postal savings. However, the combination of two or more mail streams in a production setting has proven complex and difficult.
One embodiment of the invention is directed to a method comprising providing a master mailing list comprising a sequence of recipients, providing printed products to form a first mail stream on a printing line, providing printed products to form a second mail stream on a printing line, and placing printed product from the second mail stream onto a printed product of the first mail stream to create the combined mail stream in the sequence of the master mailing list.
Another embodiment of the invention is directed to a method comprising providing printed products to form a first mail stream on a finishing line, providing printed products to form a second mail stream on a finishing line, and placing printed product from the second mail stream onto a printed product of the first mail stream to create a combined mail stream.
Another embodiment of the invention is directed to a method comprising conveying a stream of printed products in series toward a printer, monitoring the thickness of each of the printed products of the stream of printed products, adjusting the height of the printer based on the thickness of each of the printed products of the stream of printed products to be delivered to the printer, and printing with the printer indicia on each of the printed products of the stream of printed products.

The invention includes a method for combining at least two separate mail streams in a finishing process. In one embodiment, one mail stream is from a binding line, such as a stitcher or perfect binder, and the other mail stream is from a loader, such as a shuttle hopper. However, it should be noted that the mail steams can be from other pieces of finishing equipment or from other manufacturing lines as will be detailed below. Likewise, the method of combining at least two mail streams can be accomplished anywhere on a printing line including on a finishing line such as a binding line.
With reference to
The feeding of the printed pieces to the finishing line 10 is controlled by a controller 16 such as the FCS controller available from QTI of Sussex, Wis. The controller 16 controls assembly of the printed products according to a master mailing list of recipients. The assembly can be demographic such that the controller 16 assembles a printed product based upon individual recipient information, as is known in the art. Further, the controller 16 may control the simultaneous assembly of more than one title or version of the printed products using the pockets 12 and binder 14, a process termed multi-binding. For example, two titles can be simultaneously assembled and bound using the same set of pockets 12 and binder 14. The two titles would be assembled according to a master mailing list in a specific order to obtain optimum postal discounts. Three or more titles could also be assembled using this multi-binding process.
After binding, the printed products are conveyed to and trimmed by a trimmer 18. After the trimmer 18, this first mail stream may enter a buffer storage system or buffer 20. If a buffer is employed, the buffer 20 may be a conveyor type buffer such as that available from Sitma of Italy as model 953 and may be able to hold 100-400 printed products. The buffer 20 holds then delivers the printed products to a mail table 22 as needed and as controlled by the controller 16 as will be further explained below.
Preferably, a second mail stream enters the finishing line 10 at the mail table 22 via a loader 24 such as a shuttle hopper. It should be noted that other types of equipment could be utilized to deliver the second mail stream to the mail table 22. The loader 24 feeds the printed products of the second mail stream to the same mail table 22 where printed products of the first mail stream are delivered. The second mail stream includes already bound printed products that may or may not be pre-addressed and/or bound. If pre-addressed, optionally a verification step can occur during which each printed product is checked to make sure the address indicia thereon is the same address indicia for the printed product in that sequence position according to the master mailing list.
The two mail streams are combined at the mail table 22 so an intended master mailing list sequence is produced. The master mailing list sequence includes the recipients of both mail streams. Such a combination of two mail streams is designed to increase postal discounts and/or reduce the postal rates on the combined mail stream. The sequence of the master mailing list is known to the controller 16. The controller 16 controls the assembly of the printed products of the first mail stream and controls the feeding of the printed products of the second mail stream to the mail table 22. Thereby, at the mail table 22, the two streams are combined in the proper order according to the master mailing list sequence.
According to one embodiment of the invention, when the printed products of the first mail stream exit the buffer 20, the controller 16 instructs the buffer 20 to leave gaps in the stream, i.e., empty chain slots, into which printed products of the second mail stream will be placed at the mail table 22. The controller 16 and the buffer 20 operate together to feed the printed products of the first mail stream to the mail table 22 when needed according to the master mailing list. The mail table 22 therefore runs at a faster average speed than the binder 14 to accommodate both mail streams. The number of printed products of the second mail stream delivered to the mail table 22 from the loader 24 and into the gaps determines this increased speed. In other embodiments, the controller 16 operates without a buffer to create gaps in the stream by signaling the loaders 24 or pockets 12 to leave open (i.e., not deliver printed products to) specific chain slots.
The buffer 20 has a varying output from that of its input. Printed products can be introduced into the buffer 20 without any printed products being removed from it. The opposite is also true in that printed products can be removed from the buffer 20 without any being introduced. The buffer 20 retains the printed products of the first mail stream in the order they were sent into the buffer in a first in, first out arrangement. As an output, the buffer creates the empty chain slots into which printed products of the second mail stream will be placed at the mail table 22. The buffer 20 operates at varying speeds depending upon input and output requirements which are governed by the need to deliver a particular printed product to the mail table 22 at the correct time as controlled by the controller 16.
The resulting mail stream exiting the mail table 22 is a combination of the first mail stream from the binder 14 and the second mail stream from the loader 24, with that combination being in the sequence determined by the master mailing list.
Optionally, a second mail table 26 or an extension of the mail table 22 can be used to apply address indicia to the printed products of the combined mail stream. For example, the address indicia can be applied to the printed products with an inkjet printer. The printed products in the combined mail stream are then conventionally accumulated in a stacker 28 and bundled in the bundle wrapper 30.
With this process, if the binder 14 goes down or there are other problems assembling the first stream of printed products, the finishing process can continue functioning with the printed products in the buffer 20 rather than shutting down the entire finishing line 10. This results in increased efficiency and cost savings especially if the problem can be remedied prior to the buffer 20 running out of printed products.
It should be noted that other layouts of combining two mail streams are covered by the invention. For example, printed products could be diverted to another packaging process which could include the buffer 20 and loader 24 or like components. In another example, two buffers 20 can be linked together in series to create increased buffer capacity for the printed products of the first mail stream, such as 200-800 printed products.
It should also be noted that multiple loaders 24 feeding printed products to the mail table 22 can be employed to combine more than two mail streams. For example, a second loader 24A could feed a third stream of printed products to the mail table 22.
In another embodiment of the invention, the empty chain slots that are created in the embodiment described above are temporarily utilized in the assembly of another mail stream. Specifically, the controller 16 using the master mail list sequence determines where empty chain slots need to be created into which printed products from the second mail stream will be placed by the loader 24 at the mail table 22. The controller 16 then controls the assembly of another stream of printed products with each printed product being placed temporarily into one of the empty chain slots. The printed products of this mail stream are then diverted from the finishing line 10 prior to the mail table 22 thus making the empty chain slots available for the printed products of the second mail stream, such as, for example, at a divert gate 32.
This process is particularly suited for the assembly of a newsstand version of a printed product which would have no recipient or address information associated with it and would therefore need to be in no particular sequence. Typically, the newsstand version of a title is created on the finishing line 10 either before or after subscriber versions, thus taking up additional time and resources. In the process described herein, the newsstand version is assembled and positioned at each empty chain slot position and then diverted prior to the mail table 22, thus saving time and resources in production.
According to another embodiment of the invention, the printed products of the first mail stream exit the buffer 20 or loader 24 such that the creation of gaps is reduced or eliminated, i.e., reduction or elimination of empty chain slots. Rather than insert printed products of the second mail stream into empty chain slots, the controller 16 will operate together with the loader 24 and/or buffer 20 to feed the printed products of the second mail stream directly onto the printed products of the first mail stream occupying the chain slots when needed according to the controlled sequence of the master mailing list.
The resulting mail stream exiting the mail table 22 is a combination of the first mail stream from the binder 14 and the second mail stream from the loader 24, with that combination being in the sequence determined by the master mailing list. For example, the resulting mail stream can include a series of chain slots that include either a single printed product of the first mail stream or a printed product of the second stream stacked on top of a printed product of the first mail stream. In yet other embodiments, empty chain slots could also be created by the buffer 20 or the controller 16 without a buffer to provide for the option of creating a resulting mail stream including a series of chain slots that have either no printed products, a single printed product from the first mail stream, a single printed product from the second mail stream, or a printed product of the second mail stream stacked on top of a printed product of the first mail stream.
It should also be noted that multiple loaders 24 feeding printed products to the mail table 22 can be employed in this embodiment to combine more than two mail streams. For example, a second loader 24A could feed a third stream of printed products to the mail table 22. In this example, a resulting mail stream can include a series of chain slots that have either no printed products (with a gap created by the buffer 20 or the controller 16 without a buffer), a single printed product from the first mail stream, a single printed product from the second mail stream, a single printed product from the third mail stream, a printed product of the second mail stream stacked on top of a printed product of the first mail stream, a printed product of the third mail stream stacked on top of a printed product of the first mail stream, a printed product of the third mail stream stacked on top of a printed product of the second mail stream, or a printed product of the third mail stream stacked on top of a printed product of the second mail stream stacked on top of a printed product of the first mail stream.
Optionally, the second mail table 26 or an extension of the mail table 22 can be used to apply address indicia to the printed products of the combined mail stream. For example, the address indicia can be applied to the printed products with a printer 34.
The printer 34 can be coupled to an actuator 36 that is controlled by the controller 16 to extend or retract controlled distances to adjust the vertical position of the printer 34. The control can be any type of control, including mechanical, electrical or electronic control. The vertical adjustment of the printer 34 allows printing of address indicia onto the printed product of each chain slot, regardless of the thickness of the printed product or printed products that occupy a chain slot. As described above, the overall height of the printed product/products in each chain slot depends on whether the chain slot includes a single printed product or multiple products and the thickness of the printed product/products. The controller 16 can monitor the thickness, number, and identity of each of the printed products in each chain slot and can control the actuator 36, and thereby the height of the printer 34, to the proper height to print the address indicia onto the printed product. The controller 16 may also monitor the thickness of the stack within each chain slot regardless of whether the chain slot includes a single printed product or multiple printed products. The speed of the adjustment is fast enough to continuously adjust between sequential chain slots. If address indicia is desired on any lower printed product within a stack of printed products in a chain slot, an additional printer can be used upstream of the loader stacking a subsequent printed product. Such a printer 34 can be used to print on printed products of different thicknesses and would enable such different printed products to be made in a single stream, on a multi-binding line for example. Such a printer also permits printing upon a second printed product (of various thickness) from a second stream that is combined in the same chain slot as the printed product from the first stream.
In other embodiments, the controller 16 can control the actuator 36 to move the printer 34 controlled distances to adjust the horizontal position of the printer 34. The controller 16 can be any type of control, including mechanical, electrical or electronic control. The horizontal adjustment of the printer 34 allows printing of address indicia at any desired upwardly-facing location on the printed product of each chain slot, regardless of the spine-to-face measurement and regardless of the head-to-foot measurement of the printed product or printed products that occupy a chain slot. The controller 16 can monitor the measurements of each of the printed products in each chain slot and can control the actuator 36, and thereby the horizontal location of the printer 34, such that the address indicia can be printed in any desired upwardly-facing location on the printed product. The speed of the adjustment is fast enough to continuously adjust between sequential chain slots. Such a printer 34 can be used to print on printed products having different measurements and would enable such different printed products to be made in a single stream, on a multi-binding line for example.
In yet other embodiments, the controller 16 can control the actuator 36 to move the printer 34 controlled distances to adjust both the vertical and horizontal positions of the printer 34 allowing printing of address indicia at any desired upwardly-facing location on the printed product of each chain slot regardless of the thickness, regardless of the spine-to-face measurement, and regardless of the head-to-foot measurement of the printed product or printed products that occupy a chain slot.
The printed products in the combined mail stream are then accumulated in a stacker 28 and bundled in the bundle wrapper 30.
