- 34/66 Sive incremental Portions of a Sheet in face-to-face 3,435,751 4/1969 Goodman et a].
- 34/162 Contact with the flat surface as it is being guided for at 3,447,247 6/1969 Daane 34/122 least a predetermined period as the sheet moves along 3,449,54 1969 Adamek et al. 219/216 the path and furthermore, provides a flow of cooling 3,515,855 6/1970 Mix, Jr 432/59 air f the f 3,517,164 6/1970 Huggins et aL.
- This invention relates to sheet handling and in particular to an apparatus for preventing curl in sheets subject to processing by application of heat and pressure.
- a guide apparatus for sheets processed by heat and pressure having a thermally conductive flat surface for establishing, downstream of the processing station, a sheet travel path, the path being substantially complanar with the plane of sheet travel in the processing station.
- Vacuum means cooperating with the flat surface, maintains successive incremental portions of a sheet being guided in face-to-face contact with the surface for at least a predetermined period as the sheet moves along the path and, furthermore, provides a flow of cooling air for the surface.
- FIG. 1 is a side elevational view, in section, of the sheet guide and cooling apparatus according to this invention showing its relation to an exemplary processing station;
- FIG. 2 is a transverse sectional view of the apparatus of this invention taken along lines 2--2 of FIG- 1.
- FIG. 1 shows a sheet guide and cooling apparatus located immediately adjacent a sheet travel path P along with a sheet S having a developed image D thereon is transported.
- the sheet S is an electrophotographically produced copy sheet and the developed image D is comprised of charge-attracted toner particles.
- the apparatus 10 maintains the sheet S in a flat condition and provides for the cooling thereof, as described hereinbelow, as the sheet travels between a heat and pressure applying processing station, such as an image fixing apparatus 12, and an exit transport mechanism 14.
- the image fixing apparatus 12 is a fuser assembly having a pressure roller 16 and a heated fuser roller 18 mounted on opposite sides of the sheet travel path P for melting the particles which comprise the image D and fusing them with the sheet S.
- the rollers are relatively adjustable so as to apply both heat and pressure in controlled proportions to a sheet S passing therebetween in order to permanently fix the image to the sheet.
- the pressure to which the sheet S is subjected is regulated by a pressure controlling device 20 acting on the bearing (not shown) supporting the fuser roller 18.
- the pressure regulating apparatus 20 is mounted in a C-shaped support 22 which is hinged for movement on the bearing (not shown) supporting the pressure roller 16.
- a gear 24 controls the angular position of the support 22 by its interaction with a rack 26 on the support 22.
- the exit mechanism 14 which may be of any particular construction, is shown in this arrangement as being comprised of a set of transport rollers 30 which direct copy sheets selectively into either a first exit channel 32 or a second exit channel 32'.
- the channel 32 is a continuation of the paper path P while the second exit channel 32' is at an angle thereto and constitutes a secondary path P.
- Selection of the desired path of travel for the respective sheets is obtained by a pivotable diverter 34, the position of which is controlled by an actuator 36.
- the diverter 34 When in the position shown in full lines of FIG. 1, the diverter 34 permits a sheet S to enter the exit channel 32 maintaining its travel along the path P. If it is desired to guide the sheet into the channel 32', the diverter 34 is moved to its position shown in broken lines so as to intercept the path P in order that the sheet will be redirected along the path P.
- the sheet guide and cooling apparatus 10 has a thermally conductive flat guideplate 38 located immediately above the path P, the guideplate extending over a substantial portion of the path between the nips of the fixer assembly 12 and the exit assembly 14.
- the path P is a straight line path from the fixer assembly 12 and the exit assembly 14 and the plane of the path established by the guideplate 38 is substantially coplanar with the plane of the path through the fixer assembly.
- the location of the guideplate 38 above the path P is preferable to prevent smearing of the toner particles (located on the underside of sheet S) when in their melted condition.
- guideplate 38 has a plurality of openings 40 extending therethrough and a series of heat transfer fins 42 extending outwardly from the guideplate on the opposite side of the plate from the path P.
- a housing 44 for directing cooling air to the heat transfer fins 42 is formed, in part, by a plurality of concave sidewalls 46 interconnected with the guideplate 38, approximating the shape of the rollers so as to enable the housing to extend as close as possible to the respective roller nips.
- End walls 48 and a top wall 50 are interconnected with the remaining structure so as to form the completed housing 44.
- the chamber 52 which communicates with the intake of a vacuum blower 54 (FIG. 2).
- the chamber 52 has a first opening 56 communicating with a first opening 58 in the top wall 50 of the housing 44. Spaced from the first opening 56 is a second opening 60.
- the opening 60 communicates with a second opening62 in the top wall 50 of the housing 44.
- the flow continuity of the chamber 52 is interrupted by a plug 64 located between the first opening 56 and the second opening 60. In this manner, air drawn into the chamber 52 by the vacuum blower 54 through an open end 66 of the chamber will be forced to flow through the cooperating first openings 56 and 58 into the housing 44 and thence back into the chamber 52 through the cooperating second openings 62 and 60.
- the vacuum blower 54 is selected so as to establish a flow of air in the housing 44 and a pressure condition therein somewhat below atmospheric pressure. Therefore, a sheet traveling along the path P will be drawn into contact with the guideplate 38 due to the establishment of the subatmospheric condition communicated to the area of the path P by means of the openings 40 in the plate 38 and, as a result, the sheet will have successive incremental portions positively maintained in face-to-face contact with the guideplate to retain the sheet in a flat orientation in order to reduce any tendency for the sheet to curl.
- the guideplate 38 will be of a similar configuration in the transverse direction to maintain a uniform shape for the planes of the sheet over the entire travel path so as to prevent sheet curl.
- the heat transferred to the sheet during the fixing process will in turn be transferred through the thermally conductive plate to the fins 42.
- the flow of air across the fins 42 under the influence of the vacuum blower 54 will serve to remove the heat from the area of the fins 42 to more efficiently cool the sheet as it travels along the path P.
- the length of the guideplate 38 is selected so that the sheet will be maintained in contact with the guideplate for a predetermined period. The period is such that the heat imparted to the sheet will be substantially dissipated.
- the sheets travel along the path P at a speed of approximately ll in/sec and the,
- length of the guideplate 38 is approximately 5 inches. This has proven sufficient to permit the removal of enough heat to prevent the tendency of the sheet to curl.
- said apparatus having a fixing station guide means defining a thermally conductive sheet guide surface parallel to and closely adjacent said given plane downstream of said fixing station, said guide means including an elongated guideplate a series of openings extending therethrough, said guideplate having at least one thermally conductive fin extending therefrom to facilitate cooling of said sheet, said fin being located out of said sheet travel,
- said sheet guide further comprises a housing surrounding said thermally conductive fins and wherein said means for maintaining successive incremental portions of said sheets in face-, to-face contact with said sheet guide surface includes.
- vacuum means communicating with said housing to establish a partial vacuum therein.
- vacuum means includes a conduit open at one end, a vacuum blower connected to said conduit at the other end thereof, a plurality of intercommunicating passages between said conduit and said housing, and meansfor directing a continuous flow of cooling air at subatmospheric pressure induced by said vacuum blower past 1 said guide surface.
