Definitions

  • the present invention relates to a service apparatus for printers or other strip form, preferably having side holes for pulling.
  • printers of data processing centres and electric accounting centres are fed with forms or sheets joined in the form of a continuous strip and packaged in packs made up of one or more thousands of accordion-folded sheets.
  • the pack of forms or sheets is exhausted in a very short time so that the loading of a new pack of forms or sheets involves idle time which negatively affects productivity of the printer and hence in the last analysis the entire data processing line.
  • the principal object of the present invention is to accomplish a single piece of equipment in which the service unit for feeding the printer and the service unit for collection of the strips of sheets or forms leaving the printer are grouped organically.
  • the function of the feed service unit is to perform automatically and in time with the printer the splicing of the last sheet or form of the pack being fed to the printer with the first form or sheet of the immediately following pack in such a manner that upon exhaustion of the pack being fed the pack with which splicing was just perfomed replaces it automatically and there is no interruption in printer feeding.
  • Another problem connected with the equipment lies in the fact that, as for all highly automated equipment, more precautions are necessary to prevent work accidents as regards the unit which receives and wraps the packs of forms leaving the printer in which cutting and compressing means are operating.
  • the present invention has the object of solving the problems and drawbacks mentioned briefly above.
  • the present invention calls for a service apparatus for printers and in general for machines which utilize sheets or forms joined in continuous strips and folded accordion wise in packs of the type comprising a unit which splices the last sheet of a pack being fed to the printer with the first sheet of an immediately following pack and a receiving and piling unit for the sheets and forms treated in the printer characterized in that said units are arranged adjacent to the splicing unit positioned sideways and perpendicular to the receiving unit and in that in said receiving and piling unit for strips of forms leaving the printer the strip is guided and piled in a receptacle described by a bottom panel which is movable between a lowered or receiving position and a raised or compressing position, two vertical walls of which one is fixed and the other may move in an adjustable manner toward or away from said fixed wall, and two other vertical walls of which one may slide parallel to itself to allow access to said receptacle and the other vertical wall may be moved toward or away from said other vertical sliding wall, in this manner allowing the recepta
  • the aforesaid receptacle is provided with a cutting blade device comprising a temporary supporting plane which may move transversally to said receptacle from a position in which it allows free access to the inside of the receptacle for the strip arriving from the printer and an operating position in which it intercepts the arriving strip and constitutes with its bottom surface a board for compressing the pack of forms made up in the receptacle beneath said plane, and a cutting blade shaped in such a manner as to make a paper-knife type cut of the strip of forms or sheets at a crease of said strip, said blade being connected to said temporary supporting plane in a manner movable between a withdrawn or rest position in which the blade is housed and protected in said plane with no poaaibility of making the cut and an operating position in which it projects in front of said temporary supporting plane in such a manner as to make said cut, there being provided first operating means for moving said temporary supporting plane between said two positions and there being provided second operating means
  • said strip of sheets or forms arriving from the printer is guided inside said receptacle by a rocker device comprising a pair of tension rollers in contact with each other and made to rotate in opposite directions to aid passage of the paper strip through the interference created thereby, said rollers being mounted on the lower ends of a pair of levers connected at their upper end by a running roller for the paper and pivoted thereon, one of said levers being pivoted at an intermediate point to the end of an operating connecting rod in reprocating motion, the other end of said connecting rod being pivoted to a crank made to rotate, means being also provided for adjusting the rotation radius of said crank and consequently the amplitude of the reciprocating motion of said connecting rod, the lastmentioned means being in turn engageable and disengageable.
  • the two units are grouped to form a very compact machine in which two different sliding planes for the paper strip 13 to and from the printer (not shown).
  • the splicing head makes the splice, as described in European Patent No. 0042619 and subsequent variants developed by the same applicant, between the last sheet of the pack being fed to the printer (not shown) and from which is unfolding the strip indicated above with reference number 13, and the first sheet of the immediately following pack, indicated schematically with reference number 14 and positioned on the supporting plane 15.
  • the strip 13 crosses the entire machine passing above the outlet service unit 12 in the direction of the arrow 16.
  • the strip of sheets or forms then returns in the direction opposite to the direction of and beneath arrow 16, entering the outlet service unit 12 from the side 17 of the machine.
  • the strip arriving from the printer crosses over the guide rollers 18 and arrives over the collection and piling receptacle 19 with accordion like folding, shown in greater detail in FIGS. 3 and 3A.
  • the receptacle 19 comprises a bottom plane 20 movable vertically by means not shown to perform the functions indicated in European Patent Application No. 82.100.731 the same applicant to which reference is made for further details.
  • the receptacle 19 comprises also four vertical walls 21,22,23 and 24. Of these the wall indicated with reference number 23 is fixed and defines the greatest extension of the receptacle together with the side wall 24 which however is made of transparent material and slides parallel to its lie plane between a position in which it completely closes access to the receptacle 19 while allowing vision and inspection of its interior and a withdrawn position in which it allows access to the interior of the receptacle.
  • the walls indicated with reference numbers 21 and 22 are movable toward and away from the walls opposite thereto, walls 23 and 24 respectively.
  • For this purpose in the bottom plane are made two groups of slits indicated with reference numbers 25 and 26 respectively.
  • the wall indicated with number 21 is formed of vertical strips 27 joined together by a peripheral frame so that the wall 21 is movable along the slits 25 toward and away from the wall 23.
  • the wall 22 is formed partially of vertical strips 28 which slide in the slits 26 toward and away from the transparent wall 24.
  • They are preferably motorized rack devices operated by sensors which take the aforesaid dimensions upstream from the outlet service unit.
  • the strip 13 arriving from the printer is drawn by guide rollers 18 and two drawing conveyors 29 above the receptacle 19 where it is guided and piled accordion wise by a rocker unit. It should be observed that the accordion like folding is facilitated by the fact that the strip is already folded in this manner when it comes from the pack which feeds the printer.
  • the rocker unit comprises a running roller 30 for the strip mounted between two side levers 31 and 32 pivoted at their upper ends to the side panels 33 and 34 of the machine.
  • a horizontal bar 35 in which is made a slit 36 for passage and guiding the paper which passes beneath the'bar 35 through the interference of two tension rollers 37 and 38 which are rotated in the direction of the arrows 39 by an electric motor 40 which is also integral with the lever 31 and hence with the rocker unit.
  • a mechanism comprising the connecting rod 41 whose end is made integral with the lever 32 by means of the pin 42, the other end of the connecting rod being pivoted on a gear 43 which acts as a crank and is rotated by drive means not shown.
  • the end 44 of the connecting rod is movable in an adjustable manner along the vertical diameter of the gear 43, consequently changing the amplitude of the horizontal travel of the free end of the connecting rod 41 and hence the amplitude of oscillation of the lever 32 and of the entire rocker unit.
  • Said adjustment is also performed in a manner dependent on the dimensions or shape of the forms or sheets making up the strip 13.
  • a device comprising a vertical rod 45 fitted with a handgrip 46, the lower end of the rod being movable in a box 47 against the counteraction of a compression spring 48.
  • the rod 45 is connected to the end 44 of the connecting rod.
  • rollers 37 have zones 49 of nonslip material so that the strip of paper cannot slide back.
  • the temporary supporting plane and blade unit At a height intermediate between the rollers 37 and the inside of the receptacle 19 is mounted the temporary supporting plane and blade unit.
  • This unit comprises a plane 50 which can move between a position in which it is completely withdrawn without interfering with the upper opening of the receptacle 19 and an operating position in which it intercepts the strip of forms or sheets arriving through the rollers 37 so that the strip 13 instead of being deposited on the bottom plane 20 piles up on the plane 50.
  • the plane 50 in the operative position as descrived in the aforesaid European Patent Application No. 82.100.731 also serves as a stop or fixed support for compressing the pile formed on the plane 20 before cutting.
  • a jack or compressed air cylinder 51 the stem of which is integral with the rear edge of the plane 50.
  • a pin 52 stops the travel of the plane 50.
  • the plane 50 also constitutes the support of the cutting blade 53 which is shaped in such a manner that engagement with the end of the crease between two sheets of the strip 13 takes place first at one point and the cut thus takes place with a "paper-knife" effect.
  • the plane 50 is tapered at its front edge while in its thickness is cut a seat 56 to house the blade 53 in a disappearing manner.
  • a pair of compressed air cylinders 54 connected by a flexible hose 55 and a sourse of pressure and vacuum (not shown).
  • an important feature of the machine in accordance with the present invention lies in the fact that the temporary supporting plane and related blade in the rest position disappear beneath the upper plane of the splicing unit to reduce occupied space.
