Definitions

  • the invention relates to a device for converting Collection on non-collection operation on one Cutting / collecting cylinder of a folder for Rotary printing press, which from collecting operation on Non-collective operation and vice versa is redistributable and in which includes at least a number of punctures, whose bearing shaft can be activated via a cam roller, that rolls on a curve body, the one end of the Cutting / collecting cylinder opposite to the housing of the The folder is adjustable.
  • JP-A-63 185 777 is a Folding device for a rotary printing press.
  • An attachable hand crank is rotatable on a shaft which several clutches are arranged.
  • One of these Clutches are disengaged, after which by pressing the Hand crank the phase position of a control curve can be changed. After the adjustment has been made, the coupling is again indented.
  • This device collects Copies on a separate collecting cylinder that is not simultaneously performs a cutting function.
  • Another folder known from the prior art according to DE 38 28 372 A1 comprises a multi-sized Collecting cylinder. There are several in this Actuators added to their two Control ends facing two each on a common Have axis rollers arranged side by side.
  • a cam carrier which takes up several cams, which are active and one Passive position can be brought.
  • the active position of the cams prevent this by supporting one of the two sensing rollers each actuator that a folding process is performed.
  • the feeler rollers can control the tax sinks of each follow the control curve and trigger folding or puncturing processes.
  • US-PS 3,865,361 discloses a folding cylinder on the A curve is recorded in the front, in which several Treads are included. Roll in these treads next to each other arranged rolls and move Puncture waves accordingly. A changeover on the folding cylinder from the collection mode to the non-collection mode is done by axially shifting the curve on the common High point of the treads. For cost reasons it is important today the production of curves with different treads, which also have to be hardened differently, if possible to avoid. The axial displacement of a curve receiving structure carries the risk that by itself game setting during operation Risk of canting of the recorded on the shaft Construction is constantly increasing. This makes using one displaceable curve at least problematic.
  • DE 17 61 134 discloses one of simple operation folding device, convertible to collective operation Rotary printing machines with a driven folding cylinder. This configuration is in a loop trained cam groove of a control disc several on the diametrically opposite inward Curved ledges embedded. Furthermore, a Gear transmission provided, with which the Speed ratio of the speed of the control disc in relation is adjustable to the speed of the folding cylinder. Of the decisive disadvantage of this folding device lies in the extensive dimensioning of the gear transmission, which is an unacceptably high number of straight teeth Includes gears that negatively affect manufacturing costs influence.
  • JP-A-47 51740 relates to a device for delaying the Fold.
  • a fixation shaft as well as a puncture shaft a folding cylinder provided, the puncture wave of a drive that is also driven in a Non-drive position is adjustable.
  • a fixation shaft as well as a puncture shaft
  • a folding cylinder provided, the puncture wave of a drive that is also driven in a Non-drive position is adjustable.
  • the end face of the folding cylinder is provided as a guide a spur gear out of engagement with another drive gear bringable.
  • the invention has for its object a Device for converting from collecting to non-collecting operation to improve on cutting / collecting cylinders so that on minimal space with few components a high one Operational safety is guaranteed.
  • the second Power transmission element on a shaft extension of the To design cutting / collecting cylinder axially displaceable comprises a first Force introduction point, which is designed as an external toothing is. There is also a in the first power transmission element second force introduction point designed as an internal toothing. Because the cam body on the first power transmission element is attached, a rotational movement in the Curve body to be initiated.
  • the first is Power transmission element in bearings in a side wall bushing rotatably received and at the same time on a bearing on Wave process added. This makes it stable Realized three-point bearing, which has the consequence that mechanical load peaks can be safely absorbed can.
  • the three-point bearing also prevents the first power transmission element based on its transverse axis on the shaft extension.
  • Parallel to the shaft extension is in a side wall bush a stub shaft mounted on which a first and a second interconnected teeth are included.
  • the second power transmission element is with the first Gearing can be brought into engagement, whereby the second Gearing the drive in the external gearing of the first Force transmission element is initiated.
  • this Operating position is a reduction in the speed of the Curve body for the speed of the cutting / collecting cylinder from 1: 2 reached. Accordingly, the cam body rotates only half as much fast as the cutting / collecting cylinder so that its Bearing shaft of the punctures only every second revolution of the cutting / collecting cylinder is activated.
  • the second power transmission element with the Internal teeth of the first power transmission element in Brought into engagement, the cam body and the rotate Circumferential surface of the cutting / collecting cylinder with the same Speed.
  • the cam body with the Internal teeth of the first power transmission element in Brought into engagement, the cam body and the rotate Circumferential surface of the cutting / collecting cylinder with the same Speed.
  • Fig. 1 shows the structure of a folder schematically.
  • a via a funnel roller 1 entering a funnel 2 Material web is folded lengthways there. After that the longitudinally folded material web pressed between draw rollers 3 and from there passes into a cylinder gap 19 which between the peripheral surfaces of a cutting / collecting cylinder 4 and one Folding cylinder 5 is formed.
  • the folding cylinder 5 rotates clockwise, the cutting / collecting cylinder 4 against the Clockwise; both cylinders have the same Peripheral speed, the diameter of the Folding cylinder 5 and the cutting / collecting cylinder 4 as 2: 1 behavior.
  • the cutting / collecting cylinder 4 is provided on its circumference with a cutting knife 6 on the one hand, while on the other hand, punctures 7 are embedded in the outer surface of the cutting / collecting cylinder 4 in the immediate vicinity of the cutting knife 6.
  • the punctures 7 consist of puncture rods 21 arranged next to one another, which are received on a bearing shaft 9 by means of puncture levers 8.
  • the folding cylinder 5, on the other hand, with a double diameter, is equipped with folding knife shafts 10 located opposite one another, each of which accommodates a folding knife 11. Offset about 90 o on the circumference of the folding cylinder 1, cutter bars 12 made of rubber and two rows of punctures 13 are added. These in turn are located at the ends of puncture levers 14, which in turn are mounted on puncture shafts 15.
  • the web area 20 entering the cylinder gap 19 becomes of punctures extended from the folding cylinder 5 and held on the circumference of the folding cylinder 5.
  • the punctures back into the folding cylinder 5 becomes by a cut between the cutting knife 6 and cutter bar 12 to a separated copy 20 '.
  • the separated copy 20 'between two folding rollers 16 pushed in and the extended Punctures 13 take an introduced one again Track area 20.
  • the copy 20 'receives a crosswise to in Hopper 2 produced longitudinal fold extending further fold.
  • the punctures 7 are out of function, they remain in the outer surface of the cutting / collecting cylinder 4 retracted.
