Abstract

Methods and apparatus for use with a trimmer to produce a plurality of books having different trim sizes are disclosed. An example method includes obtaining recipient data; based on the recipient data, generating an order to produce first books and second books, the first books having a first size and the second books having a second size, the second size different from the first size; and producing the first books and the second books in accordance with the order by: actuating a first backstop to enable a first book of the first books to engage the first backstop; trimming the first book with a cutting device; and actuating a second backstop to enable a second book of the second books to engage the second backstop; and trimming the second book with the cutting device, the first backstop at a first distance from the cutting device and the second backstop at a second distance from the cutting device.

First claim

What is claimed is:

1. A method, comprising:
obtaining, via a controller having a processor, recipient address data;
based on the recipient address data, generating, via the controller, a sequence to produce first books and second books for a first bundle of books, the first books having a first size and the second books having a second size, the second size larger than the first size;
operating the controller to produce the first books and the second books in the sequence for the first bundle by executing instructions programmed in the processor to:
determine respective sizes of the first books and second books as the first books and the second books move down a conveyor;
adjust a first modifiable distance between a first backstop and a cutting device based on the first size of the first books, the cutting device having a longitudinal axis along which a blade extends, the adjusting occurring along a first axis orthogonal to the longitudinal axis, the first backstop positioned closer to the cutting device than the second backstop;
adjust, along a second axis orthogonal to the longitudinal axis, a second modifiable distance between the second backstop and the cutting device based on the second size of the second books, the second modifiable distance different from the first modifiable distance, the second modifiable distance independently adjustable relative to the first modifiable distance, the second axis parallel to the first axis, the second axis being spaced from the first axis in a direction parallel to the longitudinal axis;
in response to determining that the first book corresponds to the first size:
actuate, along a third axis orthogonal to the first axis, toward a cutting surface, the first backstop to enable a first book of the first books to engage the first backstop; and
trim the first book with the cutting device;

in response to determining that the second book corresponds to the second size:
retract, along the third axis, away from the cutting surface, the first backstop to enable a second book of the second books to engage the second backstop; and
trim the second book with the cutting device; and

repeat a succession of actuating the first backstop toward the cutting surface and retracting the first backstop away from the cutting surface while maintaining the first modifiable distance and the second modifiable distance, wherein the succession is based on the sequence for the first bundle; and
bundling the books produced in the sequence in the first bundle.

2. The method of claim 1 , wherein trimming the first book includes moving the cutting device linearly downward relative to a cutting surface of a trimmer.

3. The method of claim 2 , wherein moving the cutting device includes descending the cutting device while not rotating the cutting device, descending the cutting device to cut a face of the first book.

4. The method of claim 2 , wherein moving the cutting device includes guiding a descent of the cutting device by moving a slot of the cutting device relative to a guide positioned within the slot.

5. The method of claim 1 , wherein the first backstop includes a first pin and a second pin,
wherein adjusting the first modifiable distance includes moving the first pin along the first axis and moving the second pin along a fourth axis, the fourth axis orthogonal to the longitudinal axis,
wherein the first axis, the second axis, and the fourth axis are parallel,
wherein actuating the first backstop includes deploying the first pin along the third axis and the second pin along a fifth axis, the fifth axis parallel to the third axis, and
wherein retracting the first backstop includes moving the first pin along the third axis and moving the second pin along the fifth axis.

6. The method of claim 1 , wherein generating the sequence for the first bundle includes maximizing a postage discount rate.

7. The method of claim 1 , wherein operating the controller to produce the first books and the second books in the sequence for the first bundle by executing instructions programmed in the processor further includes executing the instructions to interspersingly actuate the first backstop and the second backstop to produce the first books and the second books in the sequence for the first bundle.

8. The method of claim 1 , wherein operating the controller to produce the first books and the second books in the sequence for the first bundle by executing instructions programmed in the processor further includes executing the instructions to ascend the second backstop through the cutting surface, along a fourth axis parallel to the third axis, to enable the second book to engage the second backstop.

9. The method of claim 8 , wherein operating the controller to produce the first books and the second books in the sequence for the first bundle by executing instructions programmed in the processor further includes executing the instructions to descend the second backstop through the cutting surface, along the fourth axis, to enable the second book to disengage the second backstop.

10. The method of claim 1 , wherein producing the first books and the second books includes moving the first books and the second books using opposing conveyors where the first books and the second books pass between the opposing conveyors.

11. The method of claim 1 , wherein the sequence includes a first sequence, the method further including:
generating a second sequence to produce the first books and the second books for the first bundle, the second sequence to replace the first sequence; and
bundling the first books and the second books produced in the second sequence into the first bundle in place of bundling the books produced in the first sequence in the first bundle.

12. The method of claim 11 , wherein the second sequence is generated based on at least one of the first books and the second books.

13. The method of claim 11 , wherein the second sequence is based on recipient address data.

14. The method of claim 11 , wherein generating the second sequence includes designating a first set of pockets for the first book, designating a second set of pockets for the second book, and providing an empty pocket among the first set of pockets and the second set of pockets, the method further including depositing signatures on the empty pocket to produce a replacement book for a defective book.

15. The method of claim 1 , wherein the sequence includes a first sequence, the method further including:
rejecting one of the first book or the second book;
producing a replacement book for the rejected one of the first book or the second book;
generating a second sequence for the first bundle to replace the first sequence;
including the replacement book in a third sequence for a second bundle;
bundling the books produced in the second sequence in the first bundle in place of bundling the books produced in the first sequence in the first bundle; and
bundling the books produced in the third sequence in the second bundle.

16. The method of claim 1 , wherein operating the controller to produce the first books and the second books in the sequence for the first bundle by executing instructions programmed in the processor further include executing the instructions to:
deliver signatures to a plurality of pockets;
leave a pocket empty to maintain the sequence;
reject one of the first book or the second book; and
produce a replacement book for the rejected one of the first book or the second book on the empty pocket.

17. The method of claim 1 , further including depositing first signature
