Definitions

  • the invention relates to a device for folding folded goods, in particular prospercts, forms, mailers and the like is located and is pivotable about the rear edge facing the third transport area.
  • DE-B-24 41 056 describes a multiple folding device in which flexible pieces of folded goods are folded around edges directed transversely to the transport direction by means of a swivel plate which can be swiveled through 180 °: after folding, the swivel plate is pulled out of the folded folded goods laterally, at right angles to the transport direction , swiveled back through 180 ° and returned to the transport path after the folded piece of folded goods has been removed.
  • this known device is suitable for folding pieces of folded goods, it does not allow folding, i.e. no sharp skin fold. It is also felt to be disadvantageous that a quick succession of the pieces of folded goods is not possible because a lateral retraction movement, swiveling back by 180 ° and advancing movement of the swivel plate is required before the next folding process can begin.
  • the invention is therefore based on the object of creating a device which not only folds folded goods, but also folds and also permits a denser sequence of folded goods.
  • a major advantage of the new device is the fact that the pieces of folded goods are positively guided between the conveyor belts until the beginning of the folding and folding process, as a result of which a rapid transport of multilayered pieces of folded goods is made possible.
  • the device has proven particularly useful for folding and folding multilayer paper sheets of various formats, paper qualities and surface qualities, e.g. through coatings. This wide range of applications is not achieved by the known folding machines. It also saves time that the double folding does not take place in successive steps, but at the same time on the front and rear edge of the swivel plate. It is important, among other things, that the subsequent item or items of folded goods can already enter the first transport section if the preceding item of folded goods is still in the third transport section.
  • the sheets 14 to be folded are fed, for example, from a collating machine to input rollers 1 ' and 2 (FIG. 1a) and between endless belts 3 of an upper group and endless belts 4 of a second group of belts through a first transport section via a pivot plate 5 in a second transport section, the swivel plate 5 lies flat on a table 6 in its initial position, is transported under a holder 7 through endless belts 8 of a third group of belts in a third transport section to a stop 9. During this transport process, the sheets 14 to be folded are safely guided through the endless belts 3 of the upper group of belts.
  • a sensor 65 responds which, via a control circuit, stops the drive for the endless belts 3, 4 and 8 of the three groups of belts and drives the pivoting plate 5 about its rear edge facing the third transport section 11 switches on counterclockwise by 180 °.
  • the front edge 12 of the swivel plate 5 lifts the endless belts 3 of the upper group of belts with the sheets 14, as can be seen from FIG. 1b.
  • the upper input roller 1 mounted in slots 13 enables the endless belts 3 to be lifted, which press the sheets 14 firmly against the front edge 12 of the swivel plate 5 and fold them in the process.
  • the arch-shaped holder 7 holds the arch 14 firmly on the rear edge 11 of the swivel plate 5 and likewise causes the arch 14 to fold at this point.
  • the pivoting of the pivot plate 5 has already occurred so far that the holder 7 dodges forward and the sheets 14 on the rear edge 11 1 and the front edge 12 of the pivot plate 5 have an acute-angled fold.
  • the Stop 9 moved out of the transport path down.
  • the swivel plate 5 After a complete swivel by 180 °, the swivel plate 5 has placed the folded sheets 14 on the endless belts 8 of the third group of belts, and at the same time the swivel plate 5 is extended onto the table 6 by extensions 15 on the holder 7 in the position shown in FIG. 1 pushed back and the drive of the endless belts 3, 4 and 8 switched on again. The transport of the folded sheets 14 through the output rollers 18 and 19 finally completes the folding.
  • FIG. 2c shows the progress of the folding
  • FIG. 2d the swivel plate 5 has deposited the simply folded sheets 14 on the endless belts 8.
  • the holder 7 with its extensions 15 has already pushed the swivel plate 5 back into its initial position on the table 6, and the simply folded sheets are fed between the endless belts 8 and the endless belts 3 to the exit rollers 18 and 19, where the folding is completed.
  • the folding device is equipped for the transport of the sheets 14 to be folded with the three groups of endless belts 3, 4, 8 (FIG. 3), each group consisting of a plurality of endless belts which are parallel and spaced apart.
  • the upper group of four endless belts 3 is guided with its lower strand over the entire length of the transport path of the folding device, specifically via the upper input roller 1, the upper output roller 18 and two upper deflection rollers 20 and 21 (see also FIG. 4).
  • the second group of four endless belts 4 forms, with its upper strand, together with approximately a first third of the lower strand of the upper group of endless belts 3, the first transport section of the transport path.
  • This second group of endless belts 4 is guided over the lower input roller 2 at the entrance and a guide roller 22 at the exit of the first transport section and over two lower deflection rollers 23 and 24.
  • the third group of endless belts 8 is guided over the lower output roller 19 and guide rollers 17 and forms with its upper run together with the lower run of the upper group of endless belts 3 the third transport section of the transport path.
  • the endless belts 8 of the third group are mounted on the lower output roller 19 and the guide rollers 17 in such a way that they are arranged in a gap with respect to the endless belts 3 of the upper group.
  • the guide rollers 17 are individually supported on arms 25 which can be pivoted together about the axis 26 of the lower output roller 19.
  • An adjusting lever 27, which is rotatably mounted on a bolt 28, is connected to the arms 25 via a link 30.
  • a table 6 on which the swivel plate 5 rests, the surface of which is flush with the upper run of the second and third group of endless belts 4 and 8.
  • the swivel plate 5 is laterally displaceably mounted between a U-shaped guide rail 36 and can be swiveled through 180 ° about its rear edge 11 (viewed in the direction of paper transport). 5 and 6 show two successive positions of the pivot plate 5.
  • the U-shaped guide rail 36 is driven by a motor 38 with a single-speed clutch (not shown), via the gears 39, 40 and 41 with a reduction ratio of 2: 1 .
  • the multi-finger bow-shaped holder 7 is pivotally mounted on a pair of links 44, 45 (FIG. 4) and is pulled against the swivel plate 5 by a spring 7a.
  • the outer fingers of this holder 7 have extensions 15, which have the task of bringing the swivel plate 5 into the position shown in FIG. 3, in which the rear edge 11 is precisely aligned with the axis of rotation of the U-shaped guide rails 36.
  • a slide 42 is articulated to the adjusting lever 27, on which a locking bracket 43 is fastened, which holds the holder 7 in the raised position in position 27 'of the adjusting lever.
  • the stop 9 is movably mounted on a pivot lever 56 and projects with its free end between the endless belts 8 in the third transport section. By pivoting the pivot lever 56 counterclockwise around its bearing pin 57, the stop 9 is moved down out of the area of the transport path. This movement is controlled by a cam disk 58 which is driven together with the gear 39 via the single-speed clutch.
  • the swivel lever 56 is connected via a tie rod 59 to an angle lever 60 which is mounted in a stationary manner on a bearing pin 61 and bears against the cam disk 58 with a feeler roller 63 under the action of the tension spring 62.
  • the position of the stop 9 in the transport path is determined by the format of the sheet 14 to be folded, and the setting is made by the actuator 64.
  • the stop 9 is equipped with the sensor 65, which responds when a sheet 14 arrives at the stop 9 and that Shutting down the drive for the endless belts 3, 4 and 8 and the connection of the single-speed clutch on the motor 38 and others controls for the pivoting of the pivot plate 5.
  • a folding comb 66 mounted on the shaft 50 consisting of five individual fingers arranged at a distance from one another, is adjusted by a setting device 67 to a distance from the web 68 which depends on the strength and number of the sheets 14 to be folded at the same time, which is the leading edge 12 of the Describes pivot plate 5 when pivoting about its rear edge 11.
  • a folding angle 71 which has an acute-angled notch 72, is mounted in each finger of the folding comb 66.
  • a counter-holder 75 is slidably mounted perpendicular to the transport path.
  • a sensor roller 77 is mounted on a roller support 76 which is firmly connected to the counter-holder 75 and which bears against a cam disk 78 which makes half a revolution with the gearwheel 40 during each folding process.
  • a tension spring 79 pulls the bent free end of the counter-holder 75 against the rear edge 11 of the swivel plate 5. Every half a turn of the cam 78, the counter-holder 75 is raised, whereby the folding of the arch or sheets 14 is supported when the holder 7 through the swivel plate 5 swings up sideways (Fig. 1c).
