DETAILED DESCRIPTION

FIG. 1 schematically shows a printing press 100 including a plurality of printing units 10 printing images on a web 12, which is passed into a folder 50. In folder 50, web 12 is cut into signatures by a cutting apparatus 14, which may be folded by a folding apparatus 20. The signatures are then delivered at high speeds by transport tapes 40, 42 to a diverter 30, which diverts the signatures into three separate streams.

FIG. 2 a schematically shows a more detailed side view of diverter 30. Diverter 30 includes rotating diverter bodies 32, 34 having respective surface lobes 36, 38 for diverting incoming signatures into three separate paths (i.e., triverting). Signatures are transported to rotating diverter bodies 32, 34 by continuous opposing transport tapes 40, 42 along a signature input stream and are output by diverter 30 in three output streams. Transport tapes 40, 42 are guided by respective rollers 70, 72 and tape guiding portions 62 (FIG. 3) of respective diverter bodies 32, 34 so transport tapes 40, 42 diverge from one another as transport tapes 40, 42 approach a diverting area 44 formed directly between respective axes 32a, 34a of diverter bodies 32, 34. A steeple 46 forming three guiding paths or streams is located on the downstream side of diverting area 44. In the embodiment shown in FIG. 2a, steeple 46 is stationary. Steeple 46 may include a first guide section 47 positioned adjacent diverter body 32 and a second guide section 49 positioned adjacent diverter body 34, which together define a slot 66 in steeple 46. Steeple 46 may be formed as two distinct pieces, with guide sections 47, 49 being separate pieces, or may be formed as a single piece, with guide sections 47, 49 being joined at outer edges thereof to define slot 66.

First guide section 47 includes a first outer guiding surface 47a adjacent the outer surface of diverter body 32 that guides signatures along a first diverting path between transport tapes 40 and transport tapes 48. Transport tapes 48 are spaced axially on and are guided by a guide roller 74, which may be driven to move transport tapes 48. Second guide section 49 includes a second outer guiding surface 49a adjacent the outer surface of diverter body 34 that guides signatures along a second diverting path between transport tapes 42 and transport tapes 52. Transport tapes 52 are spaced axially on and are guided by a guide roller 76, which may be driven to move transport tapes 52. Guide sections 47, 49 may have curved surfaces on sides thereof opposite diverting area 44 that are shaped to receive respective guide rollers 74, 76 and respective tapes 48, 52 therein. Between guide sections 47, 49, a third diverting path is delimited by slot 66 in steeple 46 formed via interior surfaces 47b, 49b of guide sections 47, 49, respectively. At least one of interior surfaces 47b, 49b guides signatures along the third diverting path between transport tapes 54, 56. Transport tapes 54, 56 are spaced axially on and are guided by respective guide rollers 78, 80, which may be driven to move transport tapes 54, 56, respectively. Guide rollers 78, 80 may also assist in guiding transport tapes 48, 52, respectively. Guide surfaces 47a, 49a may be formed with slots therein which portions of respective lobes 36, 38 (i.e., circumferential portions 36a, 36b and circumferential portions 38a, 38b) pass through during the rotation of rotating bodies 32, 34. The slots in guide surfaces 47a, 49a may be aligned with tape guiding portions 62 (FIG. 3) of respective diverter bodies 32, 34.

Each guide 47, 49 section includes a respective triangularly shaped nose 47c, 49c near diverting area 44 for diverting signatures along the three diverting paths, such that guide sections 47, 49 increase in height as they extend away from diverting area 44. Guide surface 47a extends away from nose 47c and tapers away from slot 66 so that nose 47c may contact signatures near diverting area 44 and direct signatures along the first diverting path. Guide surface 47a may extend in a straight path away from nose 47c or may be concave and extend along a curved path away from nose 47c. Guide surface 49a extends away from nose 49c and tapers away from slot 66 so that nose 49c may contact signatures near diverting area 44 and direct signatures along the second diverting path. Guide surface 49a may extend in a straight path away from nose 49c or may be concave and extend along a curved path away from nose 49c. Slot 66 begins at noses 47c, 49c and extend to the downstream edges of guide sections 47, 49 so one or both of noses 47c, 49 may contact signatures and direct the signatures along the third diverting path.

Lobes 36, 38 each include three portions that extend radially different distances from the center axes 32a, 34a of respective diverter bodies 32, 34 and thus have different radial heights. With respect to diverter body 32, lobes 36 each include a first circumferential portion 36a that extends radially a distance D1 from center axis 32a, a second circumferential portion 36b that extends radially a distance D2 from center axis 32a and a third circumferential portion 36c that extends radially a distance D3 from center axis 32a. In this embodiment, first circumferential portion 36a has the greatest radial height, second circumferential portion 36b has the next greatest radial height and third circumferential portion 36c has the smallest radial height (i.e., distance D1>distance D2>distance D3). Diverter body 34 is configured in the same manner with three circumferential portions 38a, 38b, 38c of decreasing radial height.

Diverter bodies 32, 34 may be driven by a single motor via gearing or belts, or each motor may be driven by a separate motor. Rollers 74, 76, 78, 80 may be driven by the same motor as diverter bodies 32, 34 via gearing or belts or may be driven by one or more additional motors. A controller is preferably provided for synchronizing the motor or motors of diverter 30 with motors driving printing units 10 (FIG. 1) and motors driving components of folder 50 and if, diverter 30 includes a plurality of motors, synchronizing the motors of diverter 30 with each other. In another embodiment, a single motor may drive all of printing units 10, all the components of folder 50 and all the components of diverter 30.

FIG. 2 b shows a perspective view of steeple 46 according to an embodiment of the present invention. As discussed above, steeple 46 includes two guide sections 47, 49 defining a slot 66 therebetween. Guide surface 47a is formed of a plurality of individual fingers or protrusions 47d that extend away from a base portion 47e. As shown in FIG. 2b, protrusions 47d are triangular in shape and are shaped such that guide surfaces 47a follow a concave path away from nose portions 47f of protrusions 47d that form nose 47c (FIG. 2a). Protrusions 47d are axially spaced apart from one another so as to define slots that lobes 36 may pass through during the rotation of diverter body 32. Guide section 49 is configured in the same manner as guide section 47 and is symmetrical to guide section 47 with respect to slot 66. Accordingly, guide section 49 includes a plurality of individual fingers or protrusions 49d that are triangular in shape and extend away from a base portion 49e. Protrusions 49d are also shaped such that guide surfaces 49a follow a concave path away from nose portions 49f of protrusions 49d that form nose 49c (FIG. 2a). Protrusions 49d are axially spaced apart from one another so as to define slots that lobes 38 may pass through during the rotation of diverter body 34.

FIG. 3 schematically shows a cross-sectional view of diverter body 32 along plane A-A shown in FIG. 2a. As shown in FIG. 3, first circumferential portion 36a is at the top of diverter body 36 and third circumferential portion 36c is at the bottom of diverter body 32. Diverter body 32 is positioned on a shaft 60 rotatable about axis 32a. Lobes 36 extend over the circumference of shaft 60 and are axially spaced from one another by tape guiding portions 62. Tape guiding portions 62 include discs 62a on bearings 62b for supporting tapes such that transport tapes 40 may move on other surfaces 62c of tape guiding portions 62 independent of the rotations of shaft 60 and lobes 36.

FIGS. 4 a to 4c illustrate how diverter 30 operates to divert signatures delivered by transport tapes 40, 42 in one stream into three separate streams during each revolution of diverter bodies 32, 34.

FIG. 4 a shows diverting bodies 32, 34 cooperating to guide a signature S along guide surface 47a of steeple 46 and transport tape 40 and into the transport stream formed by cooperating transport tapes 40, 48 that merge at roller 74 downstream of guide section 47. Diverter bodies 32, 34 are phased with respect to one another such that third circumferential portions 36c are aligned with first circumferential portions 38a and pass by diverting area 44 at the same time. Circumferential portions 38a, passing through slots formed in guide section 49, force signature S upward and in the embodiment shown in FIG. 4a, circumferential portions 36c are of a radial height that circumferential portions 36c do not contact signature S. Instead, circumferential portions 36c are relieved such that circumferential portions 36c allow transport tapes 40 to grip signature S along with circumferential portions 38a and guide signature forward along guide surface 47a. In alternative embodiments, circumferential portions 36c may contact and guide signature S.

FIG. 4 b shows diverting bodies 32, 34 cooperating to guide a signature S along guide surface 49a of steeple 46 and transport tape 42 and into the transport stream formed by cooperating transport tapes 42, 52 that merge at roller 76 downstream of guide section 49. Diverter bodies 32, 34 are phased with respect to one another such that first circumferential portions 36a are aligned with third circumferential portions 38c and pass by diverting area 44 at the same time. Circumferential portions 36a, passing through slots formed in guide section 47, force signature S downward and in the embodiment shown in FIG. 4b, circumferential portions 38c are of a radial height that circumferential portions 38c do not contact signature S. Instead, circumferential portions 38c are relieved such that circumferential portions 38c allow transport tapes 42 to grip signature S along with circumferential portions 36a and guide signature forward along guide surface 49a. In alternative embodiments, circumferential portions 38c may contact and guide signature S.

FIG. 4 c shows diverting bodies 32, 34 cooperating to guide a signature S between guide sections 47, 49 of steeple 46 and into cooperating transport tapes 54, 56. Diverter bodies 32, 34 are phased with respect to one another such that second circumferential portions 36b, 38b are aligned with one another and pass by diverting area 44 at the same time. Circumferential portions 38b contact signature S and guide signature S along guide surface 49b. Signature S may be also guided by guide surface 47b, although in some embodiments, only guide surface 49b may guide signature S. In the embodiment shown in FIG. 4c, circumferential portions 36b may also contact signature S to prevent signature S from following the path of guide surface 49a so signature S moves forward into slot 66 between guide sections 47, 49. In this embodiment, transport tapes 40, 42 and transport tapes 54, 56 are spaced apart from one another and the length of steeple 46 and the positions of rollers 78, 80 are preferably selected such that transport tapes 54, 56 come into contact with a lead edge of signature S before a trail edge of signature S is released by transport tapes 54, 56. In other embodiments, circumferential portions 36b may also contact signature S so that circumferential portions 36b, 38b grip signature S and move signature S forward into slot 66 between guide sections 47, 49. In embodiments where circumferential portions 36b, 38b grip signature S, the length of steeple 46 and the positions of rollers 78, 80 are preferably selected such that transport tapes 54, 56 come into contact with a lead edge of signature S before a trail edge of signature S is released by circumferential portions 36b, 38b. In alternative embodiments, additional transport tapes may be provided along guide surfaces 47b, 49b to assist in the movement of signature S from diverting area 44 to transport tapes 54, 56 and circumferential portions 36b, 38b may not grip signature S.

FIG. 5 shows a perspective view schematically showing one of each lobes 36, 38 operating with steeple 46 to divert signatures A, B and C into three separate streams. Other elements of diverter 30 have been omitted for clarity. Lobes 36, 38 are phased for second circumferential portion 36b and second circumferential portion 38b to direct signature A into slot 66 between first and second guide sections 47, 49 of steeple 46 (as shown in FIG. 4c), for third circumferential portion 36c and first circumferential portion 38a to direct signature B along the first guide surface 47a (as shown in FIG. 4a) of first guide section 47 and for first circumferential portion 36a and third circumferential portion 38c to direct signature C along the first guide surface 49a (as shown in FIG. 4b) of second guide section 49.

FIGS. 6 a and 6b show diverter 30 configured to divert signatures into two streams. In comparison to FIG. 2a, lobes 36, 38 have been removed from diverter bodies 32, 34 and replaced with lobes 136, 138. Also, guide section 47 of steeple 46 may be removed so only guide section 49 remains. Transport tapes 40 may also be removed and replaced with transport tapes 140 that extend parallel to guide surface 49b of guide section 49 and may be guided by a guide roller 178. Transport tapes 48, 54 and respective guide rollers 74, 78 may also be removed, while transport tapes 42, 52, 56 and respective guide rollers 72, 76, 80 may be left in place.

Lobes 136, 138 each include two portions that extend radially different distances from the center axes 32a, 34a of respective diverter bodies 32, 34. With respect to diverter body 32, lobes 136 each include a first circumferential portion 136a that extends radially a distance D4 from center axis 32a and a second circumferential portion 136b that extends radially a distance D5 from center axis 32a. In this embodiment, first circumferential portion 136a has a greater radial height than second circumferential portion 136b (i.e., distance D4>distance D5). With respect to diverter body 34, lobes 138 each include a first circumferential portion 138a that extends radially a distance D6 from center axis 34a and a second circumferential portion 138b that extends radially a distance D7 from center axis 34a. In this embodiment, first circumferential portion 138a has a greater radial height than second circumferential portion 138b (i.e., distance D6>distance D7). However, in contrast to the similar arrangement of the radial heights of circumferential portions 36a, 36b, 36c and circumferential portions 38a, 38b, 38c, respectively, shown in FIG. 2a, first circumferential portions 136a are not necessarily of the same radial height as first circumferential portions 138a and second circumferential portions 136b are not necessarily of the same radial height as second circumferential portions 138b. First radial portions 136a are preferably the same radial height as first radial portions 36a, 38a in FIG. 2a (i.e., distance D4=distance D1), but first radial portions 138a are preferably the same radial height as second radial portions 36b, 38b in FIG. 2a (i.e., distance D5=distance D2). Also the radial height of second radial portions 136b is preferably less than or equal to the radial height of second radial portions 36b, 38b in FIG. 2a (i.e., distance D6≦distance D2) and the radial height of second radial portions 138 is preferably less than or equal to the radial height of third radial portions 36c, 38c in FIG. 2a (i.e., distance D7≦distance D3). Accordingly, lobes 136, 138 are configured to direct signatures downward along guide surface 49a of guide section 49 and parallel along guide surface 49b of guide section.

FIG. 6 a shows lobes 136, 138 cooperating to guide a signature S into a first stream along guide surface 49a of steeple 46 and in between transport tapes 42, 52 as transport tapes 42, 52 merge at guide roller 76. Lobes 136, 138 are phased with respect to one another such that first circumferential portions 136a are aligned with second circumferential portions 138b and pass by diverting area 44 at the same time. Circumferential portions 136a force signature S downward and in the embodiment shown in FIG. 6a, circumferential portions 138b are of a radial height that circumferential portions 138b do not contact signature S. Instead, circumferential portions 138b are relieved such that circumferential portions 138b allow transport tapes 42 to grip signature S along with circumferential portions 136a and guide signature forward along guide surface 49a. In alternative embodiments, circumferential portions 138b may contact and guide signature S.

FIG. 6 b shows lobes 136, 138 cooperating to guide a signature S in a second stream along guide surface 49b of steeple 46 and in between transport tapes 140, 56 as transport tapes 140, 56 merge at guide roller 80. Lobes 136, 138 are phased with respect to one another such that second circumferential portions 136b are aligned with first circumferential portions 138a and pass by diverting area 44 at the same time. Circumferential portions 138a contact signature S and guide signature S along guide surface 49b, which is arranged and configured as a plane that is perpendicular to a plane passing through axes 32a, 32b. In the embodiment shown in FIG. 6b, circumferential portions 136b are of a radial height that circumferential portions 136b do not contact signature S. Instead, circumferential portions 136b are relieved such that circumferential portions 136b allow transport tapes 140 to grip signature S along with circumferential portions 138a and guide signature forward along guide surface 49a. In an alternative embodiment, circumferential portions 136b also contact signature S so that circumferential portions 136b, 138a grip signature S and move signature S forward along guide surface 49b.

In the preceding specification, the invention has been described with reference to specific exemplary embodiments and examples thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of invention as set forth in the claims that follow. The specification and drawings are accordingly to be regarded in an illustrative manner rather than a restrictive sense.

A method for diverting printed products in a folder comprising: guiding a first printed product from an input stream along a first surface of a steeple to divert the first printed product to a first stream;guiding a second printed product from the input stream along a second surface of the steeple to divert the second printed product to a second stream; andguiding a third printed product from the input stream along a third surface of the steeple to divert the third printed product to a third stream.

15. The method recited in claim 14 wherein the third surface and a fourth surface of the steeple define a slot in the steeple and the third printed product is passed through the slot to the third stream.

16. The method recited in claim 15 wherein the first printed product is guided along the first surface of the steeple by a first rotating body, the second printed product is guided along the second surface of the steeple by a second rotating body and the third printed product is guided along the third surface of the steeple by at least the first rotating body.

17. A steeple for a diverter diverting printed products comprising: a first guide section including a first surface and a second surface, the first surface arranged and configured for guiding printed products along a first diverting stream; anda second guide section including a third surface and a fourth surface, the third surface arranged and configured for guiding printed products along a second diverting stream, the second surface and the fourth surface defining a slot for guiding printed products along a third diverting stream.

18. A diverter for receiving printed products in a single stream and diverting the printed products into two streams comprising: a first rotating body rotating about a first axis and including first and second circumferential sections positioned around the first axis, the circumferential sections of the first rotating body extending radially different distances from the first axis;a second rotating body rotating about a second axis and including first and second circumferential sections positioned around the second axis, the circumferential sections of the second rotating body extending radially different distances from the second axis, the first and second rotating bodies diverting the printed products into two different streams at a diverting area between the first and second axes; anda steeple positioned downstream of the diverting area, the steeple including a first guiding surface for guiding signatures along a first of the two streams and a second guiding surface for guiding signatures along a second of the two streams, the second guiding surface arranged and configured as a first plane perpendicular to a second plane passing through the first and second axes.

19. The diverter recited in claim 18 wherein the first circumferential section of the first rotating body extends a greater radial distance from the first axis than the second circumferential section of the first rotating body and the first circumferential section of the second rotating body extends a greater radial distance from the second axis than the second circumferential section of the second rotating body, the first and second rotating bodies being phased with respect to one another such that the first circumferential section of the first rotating body aligns with the second circumferential section of the second rotating body to guide printed products in the first stream and the second circumferential section of the first rotating body aligns with the first circumferential section of the second rotating body to guide printed products in the second stream.

20. The diverter recited in claim 19 wherein the first circumferential section of the first rotating body extends a different radial distance from the first axis than the first circumferential section of the second rotating body extends from the second axis and the second circumferential section of the first rotating body extends a different radial distance from the first axis than the second circumferential section of the second rotating body extends from the second axis.
