Definitions

  • ATTORNEYS -rality of tortuous paths to a loading platform.
  • This invention relates to a rotary folding arrangement and, more particularly, to a method and apparatus for wrapping individual sheets of film material.
  • an object of the present invention is to provide a reliable automatic high-speed rotary folding and wrapping arrangement.
  • X-ray film is chopped into sheets and presented to a first vacuum roller with it flowing from this roller to a pair of rollers so that alternate sheets take different but symmetrical paths through the machine.
  • a porous wrapping paper is laid over each film with a lead portion of the porous paper, having approximately the same area, traveling in front of each film sheet. This leading portion is raised, compared to the relatively straight-line path of the sheet and film, by a small diameter intermittently activated vacuum roller and directed into a chute having no vacuum attachments.
  • the vac-uum securing the remaining portion of the porous paper and the film sheet itself is more easily able to pull the paper and film sheet to the folding region without excessive bending of the film.
  • FIG. 1 illustrates a schematic diagram of the present invention
  • FIG. 2 is a detail view of typical vacuum rollers
  • FIG. 3 is a detail view of a portion of the present invention illustrated in FIG. 1.
  • FIG. 1 a filnr chopper It receptive of an endles web 11 of X-ray film having a width equal to a dimension of the finished product, such as 1
  • the film chopper 10 chops the web nited States Patent 0 3,260,029 Patented July 12, 1966 11 into film sheets 13 and 13' having a length of 20", for example.
  • a first vacuum roller 12 having a continuous vacuum applied to a surface region A indicated by a row of circles.
  • the continuous vacuum carries the film sheets over a second roller 15 having a continuous vacc-um region B (shown as circles).
  • the vacuum of the region B carries the film sheets 13' to a roller 15' which is provided with an intermittent vacuum region C (as indicated by semicircles) synchronized with the chopper 10 to receive alternate film sheets from the roller 12.
  • the roller 15 is also provided with an intermittent vacuum region C, which carries the remaining alternate film sheets 13 to a roller 17 having intermittent vacuum region D.
  • the film sheets 13 travel to the region of the envelope chopper roller 19.
  • the vacuum rollers 12, 15, etc. may be activated to constrain the film sheets by one of several arrangements presently known in the web handling art.
  • a rollersection B which is continuously supplied with a vacuum at its surface through radial holes 20, which are coupled by long axial holes 21 to an arcuate vacuum nozzle 22.
  • the nozzle 22 is coupled by suitable piping 23 to a vacuum tank 24. So long as there is vacuum in the tank 24, the holes 20 will grasp and constrain any film, paper, webs, sheets, etc., that are thereover.
  • FIG. 2 An intermittent vacuum drive is also illustrated in FIG. 2 where a roller 25 is provided with similar radial holes 29 about its periphery. However, only a portion 21 of the axial holes 21 and 21 are drilled completely through the near end of the roller 25 whereby they may be evacuated by an arouate vacuum noz- 21c 22' in an intermittent vacuum region of the nozzle 22. As illustrated in FIG. 2, the radial holes 20 covering approximately half of the surface of the roller 25 may be evacuated by the nozzle 22'. If, at the same time, it is necessary to have continuous activation in another region of the roller 25, a second arcuate nozzle 22" may be coupled to the other end of the roller 25, where all of the axial holes 21 are open thereto.
  • the axial holes 21' may be brought out at a different radius to pass under a second arcuate nozzle (not shown) under the control of a valve.
  • sheets may be selectively transferred from roller to roller in a preselected tortuous path.
  • rollers When handling paper or film of predetermined dimensions in the maner of the present invention, it is most practicable to have rollers with peripheral dimensions equal to 1, 2, 3, etc., times the length of the sheets of material being handled. If a roller has a periphery equal to two sheet lengths, alternate sheets may be handled by having half of the roller activated in one section, e.g., nozzle 22, FIG. 2. It is also feasible by slightly more complex arrangements, to have the axial holes 21 selectively receptive of vacuum by having an arrangement generally similar to that illustrated in FIG. 2 and providing several control valves in the vacuum nozzle system. Usually, in arrangements where it is necessary to sort sheets of various quality, adjacent regions of the axial holes 21 will be engaged by nozzles positioned at slightly different radius. In some embodiments of these vacuum rollers, several overlapping rows of radial .holes 20 are provided whereby one or more of these rows :may be selectively activated.
  • each sheet 32 is provided with a crease equidistant from successive cuts.
  • the sheets 32 are carried by a continuous vacuum region B to the mating surfaces between the rollers 17 and 19.
  • a similar continuous vacuum region e conveys the sheets 32 to the roller 17.
  • the timing of the location of the cutter blade 34 is such that the wrapping paper sheet 32 leads the film 13 by a full film sheet length. Since film sheets are usually not porous, the paper is not constrained by any vacuum holes which are completely and directly covered by the film 13. Therefore, the handling of paper is accomplished by constraining the paper separately (rollers 17 and 19) or by constraining the paper sheet 32 and constraining the film sheet 13 through the porous paper (roller 38 below).
  • the conveying of both the film sheets 13 and the paper sheets 32 commences on the roller 17.
  • the wrapping paper sheet 32 is received by the continuous vacuum region F of the roller 17
  • the roller 17 conveys the film and the paper to one of the main folding rollers 38, whereupon the vacuum region G engages the porous paper continuously and, when present, engages the film sheet 13 through the porous paper.
  • An intermittent vacuum region H of a roller 40 engages the leading portion of the porous paper 32 every second revolution thereof. Alternate revolutions of the roller 40 engage the film sheet 13 with the vacuum region H being inactivated by a valve 41 (FIG. 3).
  • a valve 41 FIG. 3
  • the size of the roller 40 may be reduced to /a of the length of the film sheets 13 so that it may be activated only every third revolution. However, I have not found this necessary.
  • the peripheral dimension of the roller 40 is reduced so that any curliness of the film sheet 13 will not materially change the adherence thereof to the roller 38.
  • Use of the roller 40 in addition to the roller 17 is "further advantageous because of the fact that the film 13 tends to follow a transporting roller 38 rather than a transfer roller 40.
  • FIG. 3 where the region of the takeoff roller 40 is shown in greater detail, the apertures of the axial holes 42 of the roller 38 are approaching a vacuum nozzle 43. Under the nozzle 43 there are no axial apertures so that the wrapper paper 32 has been freed to be constrained by the axial holes 44 of the roller 40. Thus, the paper 32 has been directed into a vertical slot chute 45 which has stripper fingers 46 at its lower end to assure stripping of the paper sheet 32 from the roller surface. No vacuum or other constraining force is applied to the lead portion of the paper sheet 32 at the instant the film sheet 13 reaches the point illustrated in FIG. 3.
  • the holes 42 are covered by a means (not illustrated) to allow constraining of both the paper and film in the region G by a nozzle (of the type illustratedat 22" in FIG. 2) on the far side of the roller 38.
  • th film sheet 13' which has traveled over the symmetrical rollers 15', 17', 38, 40' (FIG. 1) and the wrapper paper 32'. The travel of this film and its wrapper are being controlled by a vacuum nozzle 43 co-operating with the roller 38. As the rollers 38 and 38' continue their cycle, the film sheet 13 will move into the lower position immediately behind the film sheet 13' to complete the folding operation. It should be noted that portions of the porous papers 32 and 32 reside in the chute 45 at the same time. In order to prevent damaging engagement therebetween, I have provided a separating means in the form of a separator 47.
  • the detector is positioned to provide a beam which will, under normal operating conditions, continuously engage either paper 32 or paper 32'.
  • a vacuum region I carries the wrapped film sheets 13 and 13' to a stacking region indicated by a receptacle 50 where the wrapped film sheets are collected.
  • a receptacle 50 Above the receptacle 50 are stripping fingers 52 which assure that the wrapped film is separated from the roller 38.
