Definitions

  • the invention relates to a folding machine for paper sheets, in particular for folding mail in inserting machines.
  • the invention has for its object to provide such a machine that meets the following conditions: the machine should be without structural change, only by changing the control program (direction of rotation, feed distance) for different types of fold, such as single fold, Z-fold, roll fold, and various Formats can be set. Likewise, the direction of rotation during folding should be easily reversible. The machine should make it possible to reliably hold even a small section of the goods to be folded during the folding process. The leg lengths of the folds should be freely selectable and easily adjustable within a large range. In particular, should also material to be folded with rigid components. For example, staples or credit cards or sample parts with which the machine can be folded easily (outside of these components) without problems.
  • the folding station has - as e.g. 5 - a cassette 1, which is rotatable about an axis 2 (indicated in FIGS. 1, 5, 7 and 11 by a center line cross).
  • the cassette 1 has two guide walls 3 and 4, between which the folded material 5 (or
  • the folded material 5 can be a paper sheet or consist of several sheets lying one above the other, which need not necessarily be of the same size.
  • inflexible components such as paper clips, a check card or, for example, a flat, inflexible pattern
  • the good 5 (or 32) must be inserted into the cassette 1 such that the smaller sheets at least partially and inflexible components go completely into the cassette 1, that is to say in the insertion direction 7 before the fold to be produced at A (or C).
  • the part a of the good 5 (or the part c, d of the good 32) which has been introduced so far into the cassette 1 remains, as can be seen in the following, even in all processes; it is, as explained further below, in the cassette 1 fixed.
  • the axis 2 extends transversely to the direction of insertion 7, parallel to the guide walls 3 and 4.
  • the cassette edge 6 passes, on which the part a of the good 5 (or c, d of the good 32) passes.
  • a spring-loaded pressure roller namely when rotating counterclockwise the pressure roller 9, FIGS. 8 and 14, with an opposite rotation, the pressure roller 10, Fig. 18.
  • the point A (or C) of the folding material 5 ( or 32) to the edge of the cassette 6 rolled and folded around him on the edge strips adjacent to him on the outside of the cassette, because the pressure roller 9 or lo runs over this edge strip.
  • FIGS. 10, 16, 20 as for a single fold (Fig. 2) from Fig. 5 to 10, for the second fold of a Z-fold (Fig. 3) from Fig. 11 to 16 and for the second fold of a roll fold (Fig. 4) from Fig. 11, 12 and 17 to 20 can be seen and described in more detail below.
  • the cassette 1 is equipped with two pairs of conveyor rollers 13, 14 and 15, 16, which are mounted on the outside of the guide walls 3 and 4, protrude through recesses in the guide walls and through one explained in connection with FIGS. 21/22 and 23 below Gearboxes in the initial position of the cassette 1 (FIGS. 5 and 11) before their rotation and in their end position (FIGS. 10, 16, 20) after the rotation are driven in order to insert part a of the item 5 to be inserted into the cassette 1 (or c, d of the goods 32), as can be seen in FIGS. 5 and 6 (or 11 and 12), and in order to transfer the goods merely folded at the edge of the cassette 6 to the rotating pair of folding rollers 11, 12 (FIG. 10 , 16, 20).
  • Each roller of the conveyor roller pairs 13, 14 and 15, 16 is assigned one of four further rollers 19 to 22, which is arranged at a distance from the conveyor roller, which enables the pressure roller to run over the edge strips, and is driven at its peripheral speed, by the mutually associated rollers with correspondingly dimensioned, intermeshing gears (not shown) are connected to one another in a form-fitting manner or by friction.
  • the pressure rollers 9, 10 are each rotatably connected to a gear (not shown) which meshes with the gear of one of the other rollers 19 to 22 in the position of FIG. 10 or 16 or 20, the rollers, for example 9 and 22 , have the same peripheral speeds.
  • the pressure rollers 9 and 10 are mounted on arms 23, 24, the movement of which is limited by stops 25, 26, for example the arm 23 in FIG. 8 being at a greater distance from the stop 25 than in FIGS. 9 and 10, so that the The pressing force of the spring-loaded pressure roller, for example 9, is greatest when it runs over the cassette edge 6 and is smaller when it then runs over the further roller 22 (FIG. 9) or rotates with it (FIG. 10).
  • the folded material is, as already described in part and shown in FIGS. 5 and 6, up to the point A at which folding is to take place (In the example, a center line of the folded material 5), inserted into the cassette 1.
  • a pair of feed rollers 29, 30 and the pairs of conveyor rollers 13, 14 and 15, 16 are driven at the same peripheral speeds in accordance with the feed path required for this purpose, for example by means of a stepper motor (not shown) controlled accordingly.
  • the pressure roller 9 rolls a short distance on the outside of the cassette 1, as a result of which the folded material is folded through 180 °. Then the pressure roller runs on the roller 22.
  • the rotation of the cassette reaches 180 °, its edge 6 is in front of the pair of folding rollers 11, 12, FIG. 9.
  • the pairs of conveyor rollers 13, 14 and 15, 16 are opposite to the direction in which they were previously driven (Fig. 1) for inserting the folded part a into the cassette 1, driven by feed.
  • the folded material is transferred from the cassette 1 to the pair of folding rollers 11, 12, which runs at the same peripheral speed as the rollers 13 to 16.
  • the fold previously formed between the edge of the cassette 6 and the pressure roller 9 is pressed together to form a fold.
  • next folded material on the cassette edge 31, which lies opposite the cassette edge 6, as explained for the previous cassette position in connection with FIGS. 5 and 6, can be introduced into the cassette 1 and subsequently the one in connection with FIGS 10 explained process can be repeated with this next folded material.
  • a Z-fold (FIG. 3) according to FIGS. 11 to 16 or a roll fold (FIG. 4) according to FIGS. 11, 12 and 17 to 20 can be obtained by a second folding process at point C, by the material again by the same station or by an adjoining one.
  • second station is performed (cf. the two successive stations I and II in Fig. l).
  • Fig. 1 shows further construction parts of the folding station, the states of the two stations I and II being not coordinated to show details; and sheets of different sizes are folded.
  • station I In the event that a sheet a, b is to be folded once in the middle at A, the station I is shown in a state which lies between the states shown in FIGS. 9 and 10. Station II is shown in the position that corresponds to the position in the event that the first third of a sheet in station I has been folded to form a single fold at B and the pre-folded material is to be further folded to form a Z or roll fold Fig. 14 or 18 corresponds.
  • the guide walls 33 and 34 like the guide walls 3 and 4 of the cassettes 1 (not shown), have cutouts through which the corresponding axially divided rollers 29, 30 and 11, 12 project. Between the pair of folding rollers 11, 12 of station I and the pair of feeding rollers 29, 30 of station II, a folding material guide 35 is arranged. Each cassette 1 is equipped with two guide walls 36, which keep the part b or e of the folded material hanging out of it from the rollers 13 to 16 and 19 to 22.
  • the guide walls 3 and 4 of the cassette 1 can, as shown at stations I and II in FIG. 1, be pivoted and, for example, be controlled by a fixed control cam (not shown) in such a way that they guide the cassette 1 after insertion of the folded material on the Close the insertion side (edge 6 or 31) in order to clamp the folded material there and hold it in a defined position when the pressure roller 11 or 12 runs over this side, whereupon the walls 3 and 4 separate again in order to transfer the to enable folded folding material to the folding roller pair 11, 12.
  • the greater distance between the guide walls 3, 4 at the insertion point also facilitates the insertion of the folded material.
  • the stops 25, 26 can e.g. be controlled by a curve rotating (not shown) with the cassette 1 so that the pressure rollers 9, 10 each have the most favorable position to run on the cassette edge 6 or 31 or on the further rollers 19 to 22.
  • the pressure force can also be controlled by a cam.
  • a light barrier (not shown) is expediently arranged, which responds to the front edge of the folded material in the direction of insertion and thereby triggers a control process by which the rollers 29, 30 and 13 to 16 are driven in accordance with FIG Feed path is controlled by which the folded material has to be advanced further in order to bring the point of the folded material to be folded to the cassette edge 6 or 31 facing the pair of feed rollers 29, 30.
  • the distance of the front edge of the folded goods corresponding to this feed distance from this edge of the cassette can be adjusted.
  • the sun gear 40 of the first planetary gear is seated in a rotationally fixed manner on a shaft 41 connected to the cassette 1 in a rotationally fixed manner, which can be driven by 180 ° to rotate the cassette 1, for example by a motor controlled accordingly.
  • a web 42 is rotatably mounted, on which the planet gears 43, 44 and 45, 46 of the first and second gear are stored.
  • the sun gears 47 and 48 of the second and third gears are also rotatably mounted on the shaft 41;
  • the planet gears 49 of the third gear are each seated on a shaft 51 or 52 of a roller 13 or 15 of one of the two conveyor roller pairs which is rotatably mounted on the cassette 1.
  • the other (not shown in FIGS.
  • roller 14 and 16 of each pair of conveyor rollers is driven by a pair (not shown) of the same gear wheels, one gear on the shaft 51 and 52 and the other on the shaft of the other Roller 14 or 16 of the pair sits.
  • the first planetary gear has a rotatable ring 54 with internal teeth and external teeth.
  • the second planetary gear has a fixed ring 55 with internal teeth.
  • a toothed wheel 56 meshes with the external toothing of the ring 54 and is driven to drive the conveying rollers 13 to 16 when the cassette 1 is at rest, corresponding to the folding material feed path, for example by a correspondingly controlled stepper motor (not shown).
  • the three planetary gears have the same sun gears 40, 47, 48 and the same planet gears 43 to 46, 49, 50 and thus also the same internal toothing of the rings 54 and 55.
  • the sun gear 40 When the drive gear 56 is stationary and the cassette 1 is rotated, the sun gear 40 also rotates and drives the planet gears 43, 44, which run on the internal toothing of the now stationary ring 54 ′. Now that both rings 54 and 55 stand still, the planet gears 43, 44 are connected in a rotationally fixed manner to the planet gears 45, 46 and are mounted on the same web 42 as these, the integrally formed sun gears 47 and 48 perform the same rotation as the sun gear 40, which is rotationally fixed is connected to the cassette 1.
  • the sun gear 48 inevitably rotates with the cassette 1 and since the shafts 51 and 52 of the planet gears 49, 50 and conveyor rollers 13, 15 (and 14, 16) are mounted on the cassette 1, the planet gears 49, 50 and thus the Conveyor rollers 13, 15 (and 14, 16) still with respect to the cassette 1 when the cassette 1 is rotated with the drive wheel 56 stationary.
  • a gear 61 or 62 is seated on an end of the shaft 51 or 52 of the conveyor roller 13 or 15 projecting from the cassette 1.
  • the gear 61 and 62 mesh with a gear 63, which has a link 64a of a switchable clutch 64a / 64b is firmly connected and is freely rotatable together with this coupling member 64a on the shaft 41.
  • the other coupling member 64b is also freely rotatable on the shaft 41. It is provided with an external toothing, over which a toothed belt 65 of a belt drive, which is otherwise not shown, runs.
  • the clutch 64a / 64b In order to drive the conveyor rollers when the cassette is at a standstill, the clutch 64a / 64b is engaged and the clutch member 64b is driven by the belt drive.
  • the coupling member 64b takes the coupling member 64a with the gear 63, and the gear 63 drives the gears 61 and 62 and thus the conveyor rollers 13 and 15.
  • the clutch 64a / 64b is disengaged.
  • the coupling member 64b stops, while the gear transmission 61, 62, 63 (and the coupling member 64a) as a whole rotates together with the cassette 1 about the axis of rotation 2, so that the conveyor rollers 13 and 15 are in relation stand on the cassette 1 as required.
  • the clutch 64a / 64b can be non-positive or positive, in particular as an electromagnetic clutch. Since the conveying rollers 13 and 15 are driven to the same extent alternately in one and the opposite direction, the electrical connecting lines of the electromagnetic coupling can be guided helically or spirally with a number of turns around the axis 41 to avoid sliding contacts in order to avoid sliding contacts.
  • folding material of various sizes can be folded at a selectable point in one or the other direction, depending on the direction of rotation of the cassette, without any structural change, simply by selecting the folding material feed path. Either a single fold or the first or the second fold of a Z-fold or roll fold is obtained. It can be achieved by the choice of the direction or directions of rotation of the cassette that, for example, a part of the folded material carrying an address, regardless of whether it was up or down when it was fed, on folded goods outside. A part of the material to be folded remains flat in all processes in each folding station, so that this part can have inflexible components, such as staples, a credit card or flat patterns, without being damaged or preventing the machine from working.
