Abstract
A first paper document is vacuum-secured atop a first vacuum belt that extends from a first trailing roller to a first leading roller. A second paper document is vacuum-secured below a second vacuum belt that extends from a second trailing roller to a second leading roller. The first and second trailing rollers are laterally disposed with respect to one another with the first trailing roller being at a lower elevation than the second trailing roller and with the first leading roller positioned below the second leading roller. The first and second leading rollers are centered with respect to the first and second trailing rollers so that the first and second vacuum belts converge toward one another. The first paper document therefore underlies the second paper document when the respective leading edges of the paper documents arrive at the first and second leading rollers.
Description
- This invention relates, generally, to paper-handling machines. More particularly, it relates to an apparatus that receives a pair of documents or other paper documents disposed in lateral relation to one another and discharges them with one document in overlying relation to the other.
- Many printing machines can print two side-by-side documents in approximately the same time required to print a single document. Each document can be personalized, i.e., each of the two documents may be addressed to different individuals. However, after such documents have been printed, moving them to a discharge location with one document disposed on top of the other document is somewhat problematic. In the prior art, documents enter the machine following a forward, longitudinal path of travel. The conventional technique, now in common use, is to move both documents to the left or to the right after they have been printed, i.e., changing their path of travel from longitudinal to transverse. After both documents have traveled sideways to remove them from the first forward path of travel, a first document is then carried forward again and the second document is moved further laterally until it aligns longitudinally behind the first document. Then both documents resume their forward, longitudinal travel.
- However, such travel is parallel to and transversely offset from the first forward path of travel.
- This stopping and starting and changing of directions increases the mechanical complexity of the machine and slows it down as well. What is needed, then, is a fast, mechanically elegant apparatus that handles two documents disposed in lateral relation to one another and delivers them to a discharge station where one of the documents is positioned atop the other and where the documents do not undergo changes in direction as they flow through the machine.
- However, in view of the prior art taken as a whole at the time the present invention was made, it was not obvious to those of ordinary skill how the identified need could be fulfilled.
- The long-standing but heretofore unfulfilled need for an apparatus that receives two paper documents disposed in side-by-side relation to one another and that delivers the paper documents to a discharge station with one of the paper documents disposed atop the other is now met by a new, useful, and non-obvious invention.
- A first vacuum belt mounted at a first elevation extends between a first trailing roller and a first leading roller. The first vacuum belt engages a first paper document from below by applying a vacuum thereto and transports the first paper document to the first leading roller. The first leading roller is the lower roller of a pair of confronting, vertically disposed nip rollers.
- A second vacuum belt mounted at a second elevation higher than said first elevation extends between a second trailing roller and a second leading roller. The second vacuum belt engages a second paper document from above by applying a vacuum thereto and transports the second document to said second leading roller. The second leading roller is the upper roller of said pair of confronting, vertically disposed nip rollers.
- The pair of confronting, vertically disposed nip rollers is centered with respect to the pair of side-by-side trailing rollers. The width of each leading (nip) roller is substantially the same as the width of each trailing roller. The first and second vacuum belts therefore converge toward one another so that the first paper document is positioned below the second paper document when the first and second paper documents arrive at said first and second leading rollers.
- A primary advantage of this invention is that the path of travel of the first and second documents is not abruptly changed at any time so that a generally forward path of travel is maintained at all times.
- A closely related advantage is that such arrangement allows the novel apparatus to run much faster than a prior art apparatus where the path of travel is from longitudinal to transverse and back to longitudinal.
- These and other advantages will become apparent as this disclosure proceeds. The invention includes the features of construction, arrangement of parts, and combination of elements set forth herein, and the scope of the invention is set forth in the claims appended hereto.
- For a fuller understanding of the nature and objects of the invention, reference should be made to the following detailed description, taken in connection with the accompanying drawings, in which:
-
FIG. 1 is a top plan view of the novel apparatus; -
FIG. 2 is a front view thereof; -
FIG. 3A is the first view in a six (6) view animation depicting in plan view an increasing amount of lateral overlapping between the first and second paper documents as said first and second paper documents are transported from their respective trailing rollers to their respective leading rollers by their respective vacuum belts; -
FIG. 3B is the second view of said six views; -
FIG. 3C is the third view of said six views; -
FIG. 3D is the fourth view of said six views; -
FIG. 3E is the fifth view of said six views; and -
FIG. 3F is the sixth view of said six views. - Referring now to
FIGS. 1 and 2 , it will there be seen that an illustrative embodiment of the invention is denoted as a whole by thereference numeral 10. -
First vacuum belt 12 is mounted at a first elevation and extends between afirst trailing roller 14 and a first leadingroller 16.First vacuum belt 12 engages afirst paper item 18 from below and transportspaper item 18 to said first leadingroller 16. As best understood in connection withFIG. 2 , said first leading roller is the lower roller of a pair of confronting, vertically disposed nip rollers -
Second vacuum belt 20 is mounted at a second elevation higher than said first elevation and extends between a second trailingroller 22 and second leadingroller 24.Second vacuum belt 20 engages asecond paper item 26 from above and transports the second document to said second leadingroller 24. As best understood in connection withFIG. 2 , said second leadingroller 24 is the upper roller of said pair of confronting, vertically disposed nip rollers. - As depicted in
FIG. 1 , first and secondtrailing rollers - As also depicted I
FIG. 1 , first and second leadingrollers trailing rollers roller 16 is not visible inFIG. 1 because it is below second leadingroller 24. The width of each of said leading rollers is substantially the same as the width of each of said trailing rollers. First andsecond vacuum belts FIG. 1 . - Accordingly,
first paper item 18 is positioned substantially directly belowsecond paper item 26 when said paper items arrive atnip rollers -
Upper nip roller 24 may be positioned in leading relation tolower nip roller 16 to reduce the chances that a thick paper item will become jammed as it passes between said rollers. The respective leading ends ofpaper documents first vacuum belt 12 before startingsecond vacuum belt 20. The amount of staggering is controlled by controlling the amount of time between the starting of the two belts. -
FIG. 3A is a plan view depicting the first and second paper documents in lateral relation to one another as they enter the novel apparatus.FIG. 3B depicts the first and second paper documents, in plan view, in slightly laterally overlapped relation to one another as they begin traveling from their respective trailing rollers to their respective leading rollers.FIG. 3C is also a plan view. It depicts the first and second paper documents in more laterally overlapped relation to one another, relative to theirFIG. 3B position, as they continue traveling from their respective trailing rollers to their respective leading rollers.FIG. 3D depicts the first and second paper documents in more laterally overlapped relation to one another, relative to theirFIG. 3C position, as they continue traveling from their respective trailing rollers to their respective leading rollers, andFIG. 3E depicts the first and second paper documents in almost completely laterally overlapped relation to one another as they arrive at their respective leading rollers.FIG. 3F is a plan view depicting the first and second paper documents in completely laterally overlapped and longitudinally staggered relation to one another as they exit the nip formed by leadingrollers - Significantly,
paper items apparatus 10. When they are converged toward one another by the converging vacuum belts, they are not required to stop or slow down and they maintain their generally forward path of travel. Thus, the repeated stopping and starting caused by the prior art method of changing from a forward path of travel to a sideways path of travel and back to a forward path of travel is eliminated. The apparatus thus has a simpler construction, is less expensive to build, and can run faster with fewer jams or other malfunctions as compared to the earlier machines of this type. - It will thus be seen that the objects set forth above, and those made apparent from the foregoing description, are efficiently attained and since certain changes may be made in the above construction without departing from the scope of the invention, it is intended that all matters contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
- It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
