DESCRIPTION OF THE PREFERRED EMBODIMENTS
As shown in Fig. 1, the appaldlus 10 according to the invention, for drying ink 12 on a sheet 14 fed downstream therebeneath in a predetermined path of travel 16, is shown in a typical environment in which it is used. That is, the ink drying appaldl~ls 10 is located between ink jet printing and sheet stacking structures,respectively de~i~;n~ted 18 and 20, for drying printing ink 12 on a sheet 14 fedin a path of travel 16 defined by a conventional conveyor or belt 7 ' system 22, including a plurality of horizontally-extending belts 24 which carry the sheet 14 downstream beneath the ink drying apparatus 10 from the printing structure 18 to the stacking structure 20. Without departing from the spirit and scope of the invention, a sheet 14 may be a cut sheet, envelope or mailpiece, or the like, and the ink 12 may be printed thereon in alphanumerical or graphic form, or in any combination thereof.
As shown in Fig. 1, the ink drying apparatus 10 includes framework 30 for supporting various components thereof, including structure 32 for blowing air downwardly toward the path of travel 16 of a sheet 14. The air blowing structure 32 includes at least one, and preferably two or more electrically-operable, series connected, A.C. Motor driven, pancake-type, axial fan(s) 34. In addition, for connecting the fan(s) 34 to the framework 30, the air blowing structure 32 preferably includes an air plenum 36 including an elongate generally rectangularly-shaped upper wall 38, having the same number of opening(s) 39 formed therein as the number of fan(s) 34. The fan(s) 34 are conventionally positioned over the opening(s) 39 and suitably fixedly connected to the air plenum's upper wall 38, as by means of a plurality of fasteners 39A. Moreover, the air plenum 36 (Fig. 3) includes a pair of elongate, oppositely-spaced, side walls, 40, and a pair of oppositely-spaced end walls 42 (Fig. 2) extending between the side walls 40. The walls, 40 and 42, respectively depend from the upper wall 38 and form a generally rectangularly-shaped lower outlet opening 44 of the air plenum 36. In addition, each of the plenum end walls 42 (Fig. 2) includes a foot portion 46, which laterally extends therefrom and is conventionally fixedly connected to the framework 30 for supporting the air plenum 36, and thus the connected fan(s) 34, in place. And the fan motor(s) are conventionally adapted to be connected to a local source of supply of A.C. power.
As shown in Fig. 1, the ink drying apparatus 10 additionally includes an elongate, open-ended member 50, which is preferably connected to the framework 30 for location thereof within the air plenum 36, beneath the fan(s) 34. The member 50 includes an elongate upper wall 52, and includes elongate, oppositely disposed, side walls 54 which each depend from the upper wall 52. The upper wall 52 (Fig. 3), and preferably each of the side walls 54, have a light reflecting inner surface 56. And, the opposite ends of each of the side walls 52 include at least one, and preferably a plurality of, tabs 58 extending therefrom which are adapted for receiving conventional fasteners 59 fixedly connecting the member 50 to the opposite end walls 42 of the air plenum 36, and thus to the framework 30, for supporting the member 50 in place within the air plenum 36.
As shown in Figs. 1-3, in order to maximize the light reflecting inner surface 56 of the member 50, the member's upper wall 52 (Fig. 2) preferably includes a longitudinally-extending peak edge 60, which is formed therein substantially midway between the depending side walls 54 for dividing the upper wall 52 into oppositely facing sections 62 thereof which are inclined downwardly from the peak edge 60 to the depending side walls 54. As thus constructed and arranged, the upper wall 52 has a substantially inverted-V-shape in transverse cross-section.
In addition, for maximizing the flow of air blown through the member's upper wall 52 by the fan(s) 34, each of the upper wall sections 62 includes a plurality of elongate, parallel-spaced, louvers 66 formed therefrom, which extend transversely of the longitudinally length of the wall section 62. Each of the louvers 66 (Fig. 4) includes an aperture 68 and a scoop-type vane 70. Preferably, each of the apertures 68 has a generally rectangularly-shaped perimeter edge 72. And, although each of the vanes 70 is generally rectangularly-shaped, the opposite, longitudinally-extending, ends 70A curvedly extend upwardly to the associated perimeter edge 72. Thus each of the vanes 70 laterally extends substantially entirely downwardly from the associated perimeter edge 72 and in a direction extending downstream relative to the path of travel 16, for directing air from the air blowing structure 32 at an angle 74 which is inclined toward the direction of the path of travel 16. Preferably, each of the vanes 70 subtends an angle 74 of substantially thirty degrees with respect to the associated aperture perimeter edge 72. Moreover, in the preferred embodiment, one or more or each of the louver perimeter edges 72 defines an aperture area 72A which is greater than the area dimension of the vane 70 associated therewith.
As shown in Figs. 1 and 3, the ink drying apparatus 10 additionally includes structure 80 for providing infrared light 82. The light providing structure 82 includes at least one, and preferably two, elongate, parallel-spaced, electrically-operable infrared lamp(s) 84. Each of the lamps 84 is loosely physically connected to the framework 30 for location thereof within the light reflecting member 50, preferably by mounting the lamp(s) 84 within oppositely-spaced apertures 86 formed in the air plenum end walls 42 and on oppositely-spaced supports 37 which are fixedly connected to the framework 30. Moreover, the light providing structure 80 includes a plurality of electrical leads 88 (Fig. 2), which extend from the opposite end terminals 89 of each lamp 84 to one or the other of two terminal blocks 39A and 39B (Fig. 2) mounted on the upper wall 38 of the air plenum 36. And, for electrically insulating the terminals 89 from surrounding metal structures, the light providing structure 80 preferably includes a pair of oppositely disposed insulation members 89A which are L-shaped in transverse cross-section and have one leg connected to the framework 30 beneath an associated terminal 89 and the other leg extending upwardly therefrom opposite the free end of the associated terminal 89.
As shown in Fig. 2, for energizing the lamp(s) 84 and fan motors, the terminal blocks 39A and 39B are conventionally electrically connected to one another and adapted to be connected to a local source of supply of power via a conventional on-off switch 90. Preferably, the ink drying apparatus (Fig. 2) additionally includes one or more slow-acting thermal overload switches 91 and, in addition, one or more bi-metallic self-resetting fast-acting thermal overload switches 92, which are mounted on the opposite sections 62 of the light reflecting member's upper wall 52, at the downstream end thereof, and conventionally electrically connected in series with one another and with the lamp(s) 84 via the terminal blocks 39A and 39B.
As shown in Figs. 1-3, the ink drying apparatus 10 further includes structure 95 for guarding against a sheet 14 being fed into engagement with the infrared lamp(s) 84.
Preferably, the lamp guarding structure 95 includes a plurality of first, elongate, generally U-shaped, parallel-spaced, metal rods 96. The rods 96 each have their opposite ends conventionally fixedly connected to the framework 30, as by welding, such that they respectively depend from the framework 30 for deflecting a sheet 14 fed thereagainst downwardly toward the path of travel 16. In addition, the lamp guarding structure 95 includes a plurality of second, elongate, generally U-shaped, parallel-spaced metal rods 98 which are conventionally fixedly connected, as by welding, to the first rods 96 at spaced intervals longitudinally of the length thereof for deflecting a sheet 14 fed thereagainst downwardly toward the path of travel 16.
As shown in Fig. 1-3, to protect users against exposure to, or contact with the high temperature components of the ink drying apparatus 10, the apparatus 10 additionally includes an elongate cover 100 for the fan(s) 34, light reflecting members 50 and lamp(s) 84 which are each located within the cover 100. And the cover 100 is suitably connected to the framework 30. The cover 100 preferably includes a substantially rectangularly-shaped upper wall 102, having a plurality of air inlet openings 102A formed therein. In addition, the cover 100 includes oppositely spaced side and end walls, respectively designated 104 and 106, which depend from the upper wall 102. As thus constructed and arranged, the depending walls, 104 and 106, form an elongate, substantially rectangularly-shaped, lower opening 108 of the cover 100 through which light from the lamp(s) and light reflecting member 50, and air from the fan(s) 34, passes downwardly toward the path of travel 16.
As shown in Figs. 1-3, the ink drying apparatus 10 also includes structure 110 for mounting the framework 30, and thus the cover 100, air blowing structure 32, light reflecting member 50, infrared lamp(s) 84 and lamp guarding structure 95, in overhanging relationship with a conveyor belt system 22. The mounting structure 110 preferably includes a pair of parallel-spaced metal rods 112, and, suitably connected to the opposed ends of the each of the rods 112, a leg member 114 which is conventionally constructed and arranged for seating on a typical commercially available, conveyor system 22, and supporting the framework 30 above the conveyor system 22 such that the height "h" which the lamp guarding structure 95 is disposed above the system's conveyor belt(s) 24 is sufficient to permit the passage therebeneath of conventionally-sized sheets 14. In addition, the mounting structure 110 includes a pair of elongate, parallel-spaced, channels 116 formed by the framework 30. And, the channels 116 are conventionally transversely dimensioned relative to the diameters of the respective rods 112 for receiving the rods 112 therein in a manner such that the framework 30 is slidably movable, longitudinally of the length of the rods 112. As thus constructed and arranged the ink drying apparatus 10 may be mounted in overhanging relationship with the path of travel 16 of respective sheets 14, fed downstream on a conveyor system 22, in a manner such that the framework 30, and thus the respective components, 100, 32, 50, 84 and 95 carried thereby, are slidably movable on the rods 112 in a direction extending transversely of the path of travel 16, to permit selective location thereof above the ink markings on sheets 14 in the path of travel 16. Further, the capture the ~ 7 mounting rods 112 within the channels 116, the upstream and downstream ends of each of the first rods 96 of the lamp guarding structure 95 are configured to extend beneath the mounting rods 112 and in overlapping relationship with the channels 116 which they are suitable fixedly attached, as by welding.
In operation, as a sheet 14 marked with printing ink 12 is fed downstream in the path of travel 16 from the ink jet printing structure 18 and beneath the ink drying apparatus 10 to the stacking structure 20, infrared radiant energy or light from the infrared lamp(s) 84 heats the ink 12, causing the water content thereof to vaporize. Whereupon, the water vapor 120 is entrained by air 122 from the fan(s) 34, which is directed downstream by the vanes 70 of the light reflecting member 50, and swept thereby downstream from beneath the ink drying apparatus 10. Since the vanes 70 direct the flow of air downstream beneath the ink drying apparatus 10, and thus for the most part in the direction of the path of travel 16, rather than vertically downwardly toward the path of travel, the higher air pressure boundary layer formed thereby immediately above an ink bearing sheet 14 is minimized sufficiently to urge the sheet 14 downwardly and into engagement with the conveyor belts 24 rather than move tending to the sheet 14 relative to the belts 24.
In accordance with the objects of the invention thus has been described apparatus for drying ink on a sheet, and, more particularly on a sheet fed downstream in predetermined path of travel therebeneath.

Preferably, the ink drying apparatus (Fig. 2) additionally includes one or more slow-acting thermal overload switches 91 and, in addition, one or more bi-metallic self-resetting fast-acting thermal overload switches 92, which are mounted on the opposite sections 62 of the light reflecting member's upper wall 52, at the downstream end thereof, and conventionally electrically connected in series with one another and with the lamp(s) 84 via the terminal blocks 39A and 39B.
As shown in Figs. 1-3, the ink drying apparatus 10 further includes structure 95 for guarding against a sheet 14 being fed into engagement with the infrared lamp(s) 84.
Preferably, the lamp guarding structure 95 includes a plurality of first, elongate, generally U-shaped, parallel-spaced, metal rods 96. The rods 96 each have their opposite ends conventionally fixedly connected to the framework 30, as by welding, such that they respectively depend from the framework 30 for deflecting a sheet 14 fed thereagainst downwardly toward the path of travel 16. In addition, the lamp guarding structure 95 includes a plurality of second, elongate, generally U-shaped, parallel-spaced metal rods 98 which are conventionally fixedly connected, as by welding, to the first rods 96 at spaced intervals longitudinally of the length thereof for deflecting a sheet 14 fed thereagainst downwardly toward the path of travel 16.
As shown in Fig. 1-3, to protect users against exposure to, or contact with the high temperature components of the ink drying apparatus 10, the apparatus 10 additionally includes an elongate cover 100 for the fan(s) 34, light reflecting members 50 and lamp(s) 84 which are each located within the cover 100. And the cover 100 is suitably connected to the framework 30. The cover 100 preferably includes a substantially rectangularly-shaped upper wall 102, having a plurality of air inlet openings 102A formed therein. In addition, the cover 100 includes oppositely spaced side and end walls, respectively designated 104 and 106, which depend from the upper wall 102. As thus constructed and arranged, the depending walls, 104 and 106, form an elongate, substantially rectangularly-shaped, lower opening 108 of the cover 100 through which light from the lamp(s) and light reflecting member 50, and air from the fan(s) 34, passes downwardly toward the path of travel 16.
As shown in Figs. 1-3, the ink drying apparatus 10 also includes structure 110 for mounting the framework 30, and thus the cover 100, air blowing structure 32, light reflecting member 50, infrared lamp(s) 84 and lamp guarding structure 95, in overhanging relationship with a conveyor belt system 22. The mounting structure 110 preferably includes a pair of parallel-spaced metal rods 112, and, suitably connected to the opposed ends of the each of the rods 112, a leg member 114 which is conventionally constructed and arranged for seating on a typical commercially available, conveyor system 22, and supporting the framework 30 above the conveyor system 22 such that the height "h" which the lamp guarding structure 95 is disposed above the system's conveyor belt(s) 24 is sufficient to permit the passage therebeneath of conventionally-sized sheets 14. In addition, the mounting structure 110 includes a pair of elongate, parallel-spaced, channels 116 formed by the framework 30. And, the channels 116 are conventionally transversely dimensioned relative to the diameters of the respective rods 112 for receiving the rods 112 therein in a manner such that the framework 30 is slidably movable, longitudinally of the length of the rods 112. As thus constructed and arranged the ink drying apparatus 10 may be mounted in overhanging relationship with the path of travel 16 of respective sheets 14, fed downstream on a conveyor system 22, in a manner such that the framework 30, and thus the respective components, 100, 32, 50, 84 and 95 carried thereby, are slidably movable on the rods 112 in a direction extending transversely of the path of travel 16, to permit selective location thereof above the ink markings on sheets 14 in the path of travel 16. Further, the capture the ~ 7 mounting rods 112 within the channels 116, the upstream and downstream ends of each of the first rods 96 of the lamp guarding structure 95 are configured to extend beneath the mounting rods 112 and in overlapping relationship with the channels 116 which they are suitable fixedly attached, as by welding.
In operation, as a sheet 14 marked with printing ink 12 is fed downstream in the path of travel 16 from the ink jet printing structure 18 and beneath the ink drying apparatus 10 to the stacking structure 20, infrared radiant energy or light from the infrared lamp(s) 84 heats the ink 12, causing the water content thereof to vaporize. Whereupon, the water vapor 120 is entrained by air 122 from the fan(s) 34, which is directed downstream by the vanes 70 of the light reflecting member 50, and swept thereby downstream from beneath the ink drying apparatus 10. Since the vanes 70 direct the flow of air downstream beneath the ink drying apparatus 10, and thus for the most part in the direction of the path of travel 16, rather than vertically downwardly toward the path of travel, the higher air pressure boundary layer formed thereby immediately above an ink bearing sheet 14 is minimized sufficiently to urge the sheet 14 downwardly and into engagement with the conveyor belts 24 rather than move tending to the sheet 14 relative to the belts 24.
In accordance with the objects of the invention thus has been described apparatus for drying ink on a sheet, and, more particularly on a sheet fed downstream in predetermined path of travel therebeneath.
