Definitions

  • the invention relates to a method for folding sheets according to claim 1 and a pocket folding machine according to the preamble of claim 8.
  • Pocket folding machines and Schwertfalzmaschinen are known from the prior art.
  • the combination of pocket folding machines with Schwertfalzmaschinen is common as Kombifalzmaschine.
  • parallel folds are folded in pocket folders and cross breaks in the subsequent knife folders.
  • the sheet passes through at least the following stations in the feed-through direction of the combination folding machine: feeder, transfer table, pocket folder, knife folder, delivery arm.
  • a respective pocket folder consists of a folding pocket and three folding rollers, which are arranged in two folding roller pairs.
  • the folding rollers themselves are interconnected by means of gears, flat belts or toothed belts and are driven at the same speed via an adjustable main drive. Knife shafts or feed units are also driven by this main drive.
  • each folding roller of a pocket folder is associated with its own, independent servomotor, so that the transport speeds of the folding rollers are independently adjustable.
  • the DE 10 2008 048 287 A1 discloses a method for shingled printed sheets in a folding machine.
  • the folding machine has at least one folding station with at least one folding unit.
  • the arcuate elements are fed in a transport direction with its front edge ahead with a Unterschuppung the folding station.
  • the Unterschuppung corresponds according to the invention at most the first fold length. In such a method, the performance of the folding station can be significantly increased.
  • the object of the present invention is therefore to describe a method for folding sheets and to provide a pocket folding machine, which improve the sheet travel through the folding unit and the disadvantages of the prior art, at least partially remedy.
  • the inventive method is used for folding sheets in a Taschenfalzmaschine with at least a first pair of rollers, a downstream in the sheet running direction folding pocket and a downstream in the sheet running direction Falzwalzencru.
  • at least one of the rollers of the pair of folding rollers has on its surface a permanently higher peripheral speed than the peripheral speed on the surface of one of the rollers of the first pair of rollers.
  • the peripheral speed of the at least one roller of the folding roller pair is greater than the peripheral speed of at least one of the rollers of the first roller pair.
  • a special roller is provided with a double function, which is both part of the at least one pair of rollers and part of the pair of folding rollers. So there are provided a total of three rollers, with two rollers together form a pair of rollers and the special roller is associated with both the pair of rollers, which causes the entry of a sheet into the folder pocket, as well as the pair of folding rollers is assigned, which causes the actual fold fracture.
  • the peripheral speed of this special roller corresponds at most to Peripheral speed of a further roller of the pair of folding rollers and at least the peripheral speed of the another roller of the first pair of rollers. In other words, the speed of the special roller moves between the lower speed of the one further roller of the first roller pair and the higher peripheral speed of the another roller of the pair of folding roller.
  • the at least one first roller pair and the folding roller pair are mechanically decoupled and the rotational speeds of the first roller pair and the folding roller pair are independently adjustable.
  • a pocket folding machine with a special roller mill is required, in which the drive of the at least first roller pair and the folding roller pair are decoupled from each other.
  • the rotational speeds of the at least one roller of the folding roller pair and the at least one roller of the first roller pair are in a constant relationship to one another.
  • the rotational speeds of the rollers can not be set arbitrarily, but rather are interdependent.
  • the bowing of a sheet to be folded is determined during folding, i. measured and depending on the result of the determination of the sheet tightening the rotational speeds of at least the first pair of rollers and the Falzwalzencrues be adjusted. This can ensure that a sheet is always held under tension during the folding process and thus a high folding accuracy can be achieved.
  • all the rolls of the pocket folding machine have the same diameter and the at least one roll of the folding roll pair is driven at a higher rotational speed.
  • all subsequent folding rollers are driven at the higher rotational speed or even greater rotational speed.
  • no changes must be made to the folding rollers themselves, since these usually have the same diameter to have.
  • an adjustment of the roller drive is required so that the at least one roller of the pair of folding rollers can be driven at a higher rotational speed, the higher speed causing a sheet to be folded to be folded during the folding process.
  • At least one of the rolls of the first pair of rolls has a smaller diameter than the rolls of the pair of folding rolls.
  • the rollers of the first pair of rollers and the at least one roller of the pair of folding rollers are driven at the same rotational speed. Due to the different diameter of the at least one roller of the first pair of rollers and the rollers of the pair of folding rollers, however, there is a difference in their peripheral speeds. This speed delta of circumferential speeds, in turn, causes a sheet to be folded to become taut during the folding process and to be constantly held under tension.
  • the invention also relates to an alternative embodiment variant of a pocket folding machine with at least one first pair of rollers, a first folding pocket arranged downstream in the direction of sheet travel and a pair of folding rollers arranged downstream in the sheet running direction.
  • a respective folding unit of the pocket folding machine has a special roller with a double function, which is both part of the at least one pair of rollers and also part of the folding roller pair.
  • the Taschenfalzmaschine a drive for driving the rollers, which is associated with at least the first pair of rollers and the Falzwalzencru.
  • the special roller is a friction clutch, also referred to as a slip clutch, slip clutch or slip gear, at least indirectly coupled to the drive.
  • the special roller can be driven so that its peripheral speed between the peripheral speed of a further roller of the first pair of rollers and the peripheral speed of a further roller of the pair of folding rollers can adapt.
  • the special roll acts together with the other roll of the first pair of rolls in order to push a sheet into the folding pocket. Both rollers are pointing the same peripheral speed.
  • the special roller acts together with the other roller of the pair of folding rollers and causes the fold break in the folded sheet. In this case, the special roller is driven with the higher peripheral speed of the other roller of the folding roller pair.
  • the pocket folding machine has a drive, wherein the drive is assigned to a respective roller of the first roller pair and of the folding roller pair.
  • a special roller is provided with a double function, which is both part of the at least one pair of rollers as well as part of the pair of Falzwalzencrues.
  • the drive has tape rolls, wherein a respective roll is assigned a respective roll of tape, and the respective roll is connected to the respective roll of tape by means of an overrunning clutch.
  • the drive has to drive the tape rolls continue a moving belt, which can also be designed as a belt or belt.
  • the diameter of a respective roll of tape is less than the diameter of a - viewed in the sheet running direction - previous tape roll.
  • the diameter of the tape rolls decreases.
  • this causes the speed of rotation of the rolls of tape - viewed in the sheet running direction - increases. That the at least first roller pair is driven at a lower rotational speed than the subsequent pair of folding rollers.
  • a Taschenfalzmaschine which also does not belong to the invention, this has at least a first pair of rollers, a downstream in the sheet running direction first folding pocket and a downstream in the sheet running direction Falzwalzencru.
  • the invention viewed in the sheet running direction - between the first pair of rollers and the first folding pocket arranged at least one sheet guiding element, in particular a guide plate or a guide roller, whereby a special roller mill is formed, so that the rotational speeds of the pair of rollers and folding roller pair are independently adjustable.
  • this has at least a first drive and a second drive, wherein the first drive the first pair of rollers and the second drive is associated with the pair of folding rollers and the first pair of rollers and the Falzwalzencru are mechanically decoupled from each other.
  • the drives may in particular be individually controllable servomotors.
  • the pocket folding machines described above all rollers with the same diameter.
  • the speed delta of the peripheral speeds of the first pair of rollers and subsequent Falzwalzencru is accomplished by a corresponding design of the roller drive.
  • At least one of the rollers of the first pair of rollers has a smaller diameter than the diameter of the rollers of the pair of folding rollers.
  • the speed delta of the peripheral speeds of the first pair of rollers and pair of folding rollers is effected here by the diameter differences of the rollers.
  • the first pair of rollers is the first pair of rollers of a specific folding unit. If a plurality of folding units are provided in a pocket folding station, the said first pair of rolls can also be arranged, for example, in the second folding unit, so that the pairs of rolls of the preceding folding unit, viewed in the sheet running direction T, are arranged upstream of the first pair of rolls.
  • a folding unit of a pocket folding machine 100 is shown, as it is basically known from the prior art.
  • the folding unit comprises a first folding roller 1, a second folding roller 1.1 and a third folding roller 2.
  • the folding rollers 1 and 1.1 together form a first pair of rollers, which is also referred to as a pair of push rollers.
  • This pair of rollers 1, 1.1 pushes a sheet 30 in the folding pocket 6 of the folding unit.
  • the folding pocket 6 has a sheet stop 6.1, to which the sheet 30 is transported. The bow is guided by an upper lip 6.2 and a lower lip 6.3.
  • an upset fold 30.1 begins to form in the sheet 30, which is pulled in by the rolls 1.1 and 2 and a fold break is produced in the sheet 30, which represents the folded edge in the produced folded product .
  • the rollers 1.1 and 2 thus form a folding roller pair, which is also referred to as Switzerlandwalzencru.
  • the roller 1.1 thus forms a special roller with a double function, since it is both part of the first roller pair and part of the pair of folding rollers.
  • all rollers 1, 1.1, 2 are driven at the same rotational speed.
  • all rollers 1, 1.1, 2 have the same diameter.
  • this principle is broken and operated the folding unit with a speed delta: the roller 1 has a peripheral speed v1, which is smaller than the peripheral speed v2 of the folding roller 2, ie v1 ⁇ v2.
  • the special roller 1.1 is designed so that it can have both the smaller peripheral speed v1 and the larger peripheral speed v2.
  • the special roll 1.1 has a peripheral speed v1.
  • the peripheral speed v2 is greater than the peripheral speed v1
  • the sheet 30 is not pushed as usual through the folding unit, but rather pulled in a streamlined state by the folding unit. Folded products with high quality fold breaks can thereby be produced and, in addition, it is ensured that the sheet 30 swiftly out of the compression area, i. the area between the rollers 1, 1.1 and 2, is transported away, so that it can not come to a collision with a subsequently fed into the folding unit sheet 30.
  • Fig. 2 a view of the folding station 103 is shown, which results when the protection of the folding station 103 removed and the drive train of the folding rollers 1, 1.1, 2, 3, 4, 5 is disclosed.

  • the folding station 103 has a gear plate 25 which accommodates belt rollers 26, a deflection roller 27.1 and a drive roller 27.2.
  • the drive roller 27.2 can be connected to a first drive 28.1, not shown here, and drives a flat belt 8.
  • the tape rolls 26 are looped around by the flat strip 8 and thus driven in rotation.
  • the unit is stored in the transmission plate 25.
  • the tape roll 26, around which the ribbon 8 is looped, is held in this embodiment by means of an overrunning clutch 9 on a journal, which is flanged with the cross-coupling 24.
  • the freewheel clutches 9 cause the folding roller 1 in the intended direction of rotation can also rotate faster than the tape roll 26.
  • the tape rollers 26 downstream have a slightly decreasing diameter d3. Since all the belt rollers 26 are driven by the same flat belt 8, it is achieved by the decreasing belt diameter d3 that the rotational speed of the belt rollers 26 increases. Since according to this embodiment, all rolls 1, 1.1, 2, 3, 4, 5 have the same roll diameter d1, d2, the peripheral speed v1, v2 of the folding rolls 1, 1.1, 2, 3, 4, 5 - viewed in the sheet running direction T - to.
