Definitions

  • This invention relates to an improved transport means for feeding sheets of material through processing solutions, and more particularly to a transport means for feeding offset master sheets through a processing solution.
  • Prior art sensitized sheet material processors such as the one shown in US. Patent 2,889,762 assigned to the common assignee of this invention, have been found to be unsatisfactory for processing projection offset plate material such as the material marketed by the assignee under the trademark Project-A-Lith.
  • This material is characterized by a paper sheet that is plastic coated on both surfaces. On top of one of the plastic coatings is a sensitized emulsion.
  • the overall thickness of this sheet is in the order of .007", and the sheet is inherently stiff in contrast to typical sensitized paper. This stiffness increases the difficulty of transporting the sheets through the processor.
  • the problems of transportation are further increased by the emulsion surface becoming extremely soft as it is exposed to the developing agents.
  • the soft emulsion ordinarily has a tendency to mar or become embossed during transportation through the automatic processor, and any physical damage to the emulsion affects the quality of the final printed copy.
  • these sheets have an inherent tendency to curl, and such curl must be carefully controlled and compensated for so that the sheets can be fed accurately through the proper path of the processor without jamming or binding.
  • An object of this invention is to make a simple, economic transport means that can feed offset master sheets through processing solutions accurately without sticking, binding, jamming, or other mishap, and that can subject such sheets to uniform processing without damage to or faulty processing of the emulsion surface.
  • Another object of the invention is to make an offset master sheet transporting means that is easy to assemble and disassemble for low manufacturing costs and economy in servicing including cleaning, repair, and replacement of parts.
  • Another object of the invention is to make an offset master sheet transporter of several sub-assemblies secured together in a simple manner so that such transporter can be quickly disassembled to a few basic units or subassemblies any one of which can be replaced in whole 3,287,013 Patented Nov. 22, 1966 or in part, and any one of which can be separately repaired.
  • Another object of the invention to make a simple turning means for directing an offset master sheet from downward travel into a processing solution to upward travel out of such processing solution.
  • Another object of the invention is to improve the efficiency and reduce the manufacturing and operating costs of transport means for feeding offset master sheets through processing solutions.
  • FIG. 1 shows an isometric view of a transport means according to the invention
  • FIG. 2 shows a partial cross section of the transport means of FIG. 1;
  • FIG. 3 shows an exploded view of the transport means of FIG. 1 partially showing disassembly of such transport means.
  • an offset master sheet is fed into transporter 10 at the top of one side and travels downward, around the bottom, back up the other side, and out the top.
  • an offset master sheet is submerged in processing solution in which the transporter 10 is immersed.
  • processing solution flows through all the spaces in the transporter and contacts the emulsion surface of the offset master sheet which is preferably oriented emulsion side outward.
  • transporter 10 is driven by the processing unit in which it is installed, and such driving power is transmitted to the moving parts of the transporter 10, preferably by a gear train.
  • the uppermost and lowermost of the spur gears 12 are secured respectively to upper pulley shaft 13 and lower pulley shaft 14, and the intermediate gears 12 of the gear train are arranged as connective idlers or the means for driving roller gears as will be explained below.
  • Gears 12 can be conveniently molded of plastic and are retained on their respective shafts by retaining rings 15.
  • Pulley shafts 13 and 14 are provided with a plurality of preferably molded plastic pulleys 16 and 17 respectively.
  • continuous rollers could be substituted for pulleys 16 and 17.
  • a plurality of continuous endless belts 18 are entrained over pulleys 16 and 17 so that the belts 18 can be uniformly driven.
  • Belts 18 are arranged for engaging preferably the back of an offset master sheet for feeding it through transporter 10.
  • the natural curl of an offset master sheet after it is wetted by processing solution is such that the sheet tends to curl toward or around its back side so that it is preferred that belts 18 support the back of the sheet against such tendency to curl.
  • the belts 18 not only provide feeding power and uniform transporting motion for such offset master sheets, but carry such sheets flat against their tendency to curl.
  • Offset master sheets are guided for traveling with belts 18 by means of a plurality of rollers 20 spaced along belts 18. Rollers 20 are driven uniformly and at the same rate as belts 18 by means of roller gears 19 that engage gears 12 in a driving relation. Roller gears 19 are also conveniently made of plastic and are keyed torollers 20 by means of convenient pins 21 and are secured on their shafts by retaining rings 29.
  • Rollers 20 are mounted in a pair of sub-assemblies supported by respective frames 22 and 23.
  • Frames 22 and 23, with their respective roller assemblies, are arranged on opposite sides of the drive belt assembly and are secured together in an engaging and supporting relationship with the belt frame assembly for being supported by the latter. Simplicity is preferred in securing together the roller and belt assemblies, and is in part achieved by angle irons 24 by means of which frames 22 and 23 are bolted together.
  • a plurality of rollers 20 are arranged on each side of the belt assembly for engagement with each reach of the belts 18 to form a succession of nips between rollers 20 and belts 18 on each side of transporter 10.
  • Rollers 20 are held in place in frames 22 and 23 by sliding engagement of notched washers or sleeves 25 with a plurality of slots 26 formed in frames 22 and 23.
  • the sliding engagement of sleeves 25 with slots 26 allows rollers 20 to move short distances toward and away from belts 18.
  • Roller 20 are biased inward toward engagement with belts 18.
  • the preferred method for biasing rollers 20 is by means of springs 27 having double arms each one of which engages a retainer notch in one of the sleeves 25 that is mounted on each roller 20.
  • Springs 27 are preferably supported by being loosely slipped over spring mounting studs 28 formed on frames 22 and 23. Such mounting of springs 27 allows them to be removed by manual deformation without use of tools. This allows rollers 20 to be removed from their respective frames 22 and 23 merely by deforming springs 27 and slipping rollers 20 from their respective retaining slots 26. Reassembly of rollers 20 is accomplished by sliding the proper notches on sleeves 25 into engagement with slots 26 and manually bringing the arms of springs 27 into' engagement with the retainer notches provided therefore in sleeves 25.
  • rollers 20 Spring biasing of rollers 20 allows rollers 20 to be forced outward away from belts 18 in event of any mishap in driving sheets through transporter and thus helps prevent damage to transporter 10 that might be caused by a malfunction. Furthermore, the above described roller assembly is especially convenient to diassemble and assemble for repairs and service.
  • Offset master sheet 31 is fed from an exposure or other station through input chute 30 which directs it into the nip between upper roller and belts 18.
  • Offset master sheet 31 is preferably oriented so that its emulsion side engages roller 20 and its back side engages belts 18. In such orientation it proceeds downward on the left side of transporter 10 as illustrated through a succession of nips formed by rollers 20 and belts 18. There is only one line of engagement between each of the rollers 20 and the emulsion surface of offset master 31, so that between rollers such emulsion surface is thoroughly contacted by the processing solution in which transporter 10 is immersed.
  • a turning mech anism is arranged below low-er pulleys 17.
  • Such turning mechanism is preferably formed to provide a plurality of raised bearing ribs or ridges spaced at intervals transversely of offset master sheet 31 to reduce the sheet surface area in contact with the turning means and hence reduce the drag on offset master sheet 31.
  • such a turning mechanism can comprise a backing plate 32 to which are secured guide wires 33 that are bent to conform approximately to the curvature of lower pulleys 17.
  • Raised ribs can also be formed by means other than guide wires, for example, by corrugations or swaged integral ridges.
  • Backing plate 32 with its guide wires 33 4 is conveniently bolted or otherwise secured to frame 23 in such a position as to guide the leading edge of offset master sheet 31 around lower pulleys 17 and belts 18 entrained thereon and through the nip formed by lower roller 20 on the right side of the transporter 10 as illustrated in FIG. 2.
  • Offset master 31 is then driven upward along the right side of transporter 10 as illustrated in FIG. 2 through a plurality of nips between rollers 20 and belts 18 until the trailing edge of offset master 31 passes between the upper roller 20 and belts 18.
  • a guide means 34 is positioned above the output side of transporter 10 for guiding offset master 31 into the next transporter for subsequent trips through other processing solutions or out of the processor as the case may be.
  • Guide means 34 also is preferably formed of a plurality of transversely spaced ribs such as provided by backing plate 35 having guide wires 36 secured thereto for guiding the leading edge of offset master sheet 31 through the desired path.
  • Transporters according to the invention can be arranged in tandem for transporting offset master sheets through a plurality of processing solutions or can be arranged in other convenient ways in a variety of processors.
  • Turning or guide means such as guide means 34 can be used to direct an offset master sheet from one transporter to the next.
  • Various well known squeegees and fluid directing means can easily be used in association with transporters according to the invention, and known input and output means are satisfactory for guiding offset masters into the input and output openings of one or more transporters arranged according to the invention.
  • the transporter according to the invention accomplishes the above stated objects in successfully transporting an offset master sheet while allowing full and uniform processing of its emulsion coating without marring or damage and while compensating for the tendency of such sheets to curl as they are processed.
  • the inventive transporter at the same time is economical to build and convenient and economical to repair, service, and maintain.
  • Transporters according to the invention can be quickly disassembled and reassembled, cleaned, and repaired by relatively unskilled persons using the simplest of tools and for some operations, no tools at all.
  • Transporters according to the invention are made of con venient interchangeable parts and assemblies for further economy in repair and replacement.
