Definitions
- the invention relates to a device for adjusting the clamping gap between jaws according to the preamble of claim 1.
- a disadvantage of this folding jaw cylinder is that two cylinder bodies, which are complex to manufacture, have to be adjusted relative to one another.
- the invention has for its object to provide a device for adjusting the clamping gap between pairs of jaws of a Fa Iz k lappenzy l i nders.
- the advantages that can be achieved with the invention are, in particular, that thick folded products can be folded up to 192 pages with relatively little force. Because the center of the fold fold is precisely defined by the action of the pre-fold clamping elements, an exact transverse fold is created, especially since both halves of the signatures are each drawn into the pre-fold clamping gap by an equal amount of the penetration depth of the folding knife. Since cross folding is done in two stages, pre-folding and finishing folding, the forces required for each folding stage are reduced. By using cylindrical pre-alc clamping elements of the plier-like pre-folding clamping element system, the side surfaces of the pre-folding product connected to the pre-folding clamping gap are treated without damage. Likewise, the pre-folding of the pre-finished product up to 192 pages is free of damage due to the use of folding rollers.
- Clamping gap between jaws is the arrangement of complex, rotatable to each other
- the distance from the jaws can be preset.
- this facility is also for Pre-setting of pairs of pre-fold clamping elements located on a pre-Izzy changer is suitable.
- Figure 1 is a cross section through a schematic representation of a folder.
- FIG. 2 shows a cross section through an enlarged schematic illustration of a pre-fold clamping element which has just received a cross-fold product
- Fig. 3 shows a longitudinal section III - III of FIG. 1, wherein only one end of a prefabricating cylinder with a central control of the prefabricating element systems is shown.
- the cross-cutting and cross-folding device 18 has a known two-part, ie provided with two cutting knives 19 cutting cylinder 21, which in turn works against a known five-part folding knife, groove strip and point urzy li nder 22 - or also called transport and folding knife cylinder.
- This cylinder 22 has five folding knives and folding knife fittings 23, groove strips 24 and puncture systems 26 arranged on its circumference.
- the cross cutting and cross folding device 18 also has a rotating body, for. B. a Vorf a Izzy l i nde r 27 with a number n, z. B. three, five or seven, but preferably five, evenly spaced on its circumference 42 pre-fold clamping element systems 28, each of which cooperate with the folder armatures 23 of the cylinder 22 (Fig. 1).
- Each of the pre-fold clamping element systems 28 consists of a number m of two to ten jaw-like pairs 29 of fa Izk flap-like pre-fold clamping elements 31 arranged next to one another and spaced apart from one another in the axis-parallel direction of the pre-fold 27 ; 32nd Between the side walls 33 of the prefabrication 27 - only one side wall 33 in FIG. 3 - there are two shafts 34; 36, e.g. B. hollow shafts, with the pre-fold clamping elements 31; 32 equipped. The ends of the shafts 34; 36 are mounted in the side walls 33 of the prefabrication 27 and are mutually connected by means of shaft segments 37; 38 or gears sync ronized.
- At the center of the shaft 34; 36 is a torsion bar spring 39; 41 used.
- One end of the torsion bar spring 39; 41 is with the shaft 34; 46 connected; the other end of the torsion bar 39; 41 is fixed in a non-rigid clamping device.
- This tensioning device is located on the outside of the non-rigid side wall, which is opposite the side wall 33.
- Each pre-fold clamping element 31; 32 is formed with a thickening at its end near the periphery and on the side connected to the prefabricated product.
- the shaft 34 carries radially in the direction of the periphery 42 of the preassembly 27, finger-like, resilient supports 43 which are spaced apart from each other at a distance a.
- each support 43 carries an axially parallel direction to the preassembly 27 running cylindrical thickening 46. the end of the pre-clamping elements 31 acting on the folded product; 32 protrudes in comparison to the carrier 43.
- the second shaft 36 carries in the same way carrier 44, each with a cylindrical Thickening 47.
- the carrier 43; 44 with the thickenings 46; 47 each work as pairs 29 of pre-folding clamping elements 31; 32 together.
- the shaft 34 is rotatably on the shaft end with the clamping point of the torsion bar 39, a control arm 49.
- the control arm 49 has at its torsionally distal end a roller 51, which runs on a known be ten Vogel l Ifesten control cam 52.
- This control cam track 52 has elevations and depressions for generating a stroke for opening and closing the pre-fold clamping elements 31; 32 on.
- Rotation axes 53; 54 of the prefabricated cylinder 27 and of the folding knife, groove strip and puncture cylinder 22 are by means of an imaginary center 56 and the axis of rotation 54 is spaced by means of an imaginary center 57 from an axis of rotation 58 of the cutting cylinder 21. Below these centers 56; 57, the cylinder 22 is surrounded by tenste l l fixed paper guide rods 59.
- the front fa Izzy li nder 27 are two between the side frames 8; 9 resiliently mounted folding rollers 61, also belonging to the cross-cutting and cross-cutting device 18; 62 to finish folding the printed products.
- the transportation of prefolded printed products between the prefabricated cylinder 27 and the folding rollers 61; 62 takes place by means of two interacting belt systems 63; 64.
- the tapes of the first tape system 63 are on the circumference 42 of the prefilter 27 in between the pairs 29 of pre-fold clamping elements 31; 32 located grooves 66 and a part of the circumference of the first folding roller 61.
- the pre-fold cylinder 27 has a secant-like surface 67 which extends in the axis-parallel direction relative to the periphery 42 (Fig. 2). This surface 67 has between the closed pairs 29 of the
- Pre-fold clamping elements 31; 32 a depth t which is greater than twice the radius r of the thickenings 46; 47.
- a secant-like surface 77 extending in the axis-parallel direction to the transport and folding knife cylinder 22 is provided in each case at the point at which folding knives 23 are arranged.
- the second belt system 64 is guided above and to the side of the prefabricated cylinder 27, partly by means of belt guide rollers 68, around the prefabricated cylinder 27 and around the second folding roller 62. Both belt systems 63; 64 act together.
- the clear distance between the two folding rollers 61; 62 can be adjusted according to the thickness of the transverse fold product by means of a known folding roller gap adjustment device 74. Both folding rollers 61; 62 are therefore resiliently mounted against each other in a known manner to temporarily prevent thickening of folded products, e.g. B. after changing and connecting paper webs to compensate.
- FIG. 8 shows a known paddle wheel 69 with a known printed product ejection system 71 for displaying the transverse fold products on a delivery belt 72.
- the delivery belt 27 is preceded by a guide belt 73 located laterally on the paddle wheel 69 in the vertical direction.
- Cam track 52 adjustable.
- the control curve 52 has an axial direction Direction seen in cross section a width f, which corresponds to a multiple width g of the roller lens track.
- the control curve 52 has an incline in cross section, ie over a thickness of the control curve 84, which increases in the direction of the side frame 8.
- the control cam 8 is configured as a cup and is arranged so as to be displaceable in the axial direction E of the preassembly 27.
- the control cam 84 has a central bore and is laterally attached to a hü Isenförmi gene cam carrier 86, wherein an inner diameter of the central bore and an inner diameter of the control cam carrier 86 is the same and both parts 84; 86 are preferably formed in one piece (Fig. 3).
- the control cam carrier 86 is arranged together with the control cam 84 coaxially on a side bearing bush 87, which in turn accommodates a shaft journal 88 of the prefabricated cylinder 27 in a ball bearing 89 inside.
- the sleeve-like part of the control curve carrier 86 has on its outer surface 91 an external thread 92 and is by means of z. B. a feather key 93 on the control curve carrier 86 rotatably and ax i a l Verschi ebba r stored.
- An internal thread sleeve 94 is engaged with the external thread 92 of the control cam carrier 86 and is connected in one piece to a guide ring 96 on its side side.
- the guide ring 96 is rotatably supported with its inner tread the lateral surface 91 of the control curve r ge rs 86 and z. B. by means of a two-part be tensteen 11 fixed retaining ring 97, which engages in a circumferential surface 98 in the circumferential groove 99, secured against axial displacement.
- the internal thread sleeve 94 has on its outer surface 98 a toothing 101, which, for. B. is connected by means of a toothed belt 102 to a toothed pulley 103 of a se i teneste l Ifesten motor 104. It is rotatably coupled to the motor 104 with a rotary encoder 106.
- the internal thread sleeve 94 is rotated by means of the drive 104 to 101, so that the control rage r 86 is moved in the axial direction E as a result. Is the roller 51 on the cam track 52 in another, for. B. higher position than shown in Fig. 3, the width of the pre-fold nip 81 is reduced.
- the tread roller 51 can also have a frustoconical shape and thus adapt to the slope of the control cam 52.
- the slope of the control curve 52 corresponds to a height of the stroke of the control roller 51. It is also possible to adjust the width of the jaws of jaw cylinders.
- control cam track 52 can also be arranged in a manner which allows the control arm 49 carrying the roller 51 to be adjustable in the axial direction on the spindle or the torsion bar spring 41. It is essential, however, that the control cam 52, which is inclined with respect to the axis of rotation 53 of the prefabricating cylinder 27, is arranged so as to be relatively displaceable relative to the cam roller 51.
- the roller 51 located on the control arm 49 can also run on a control cam track, seen in cross section, which is flat and runs in the axial direction 53 of the preassembly 27.
- the cylindrical support roller serves to support the axial forces generated by the control cam.
- a procedure for cross-folding signatures is as follows.
- signatures 78 are cut, which on their leading edge in the running direction B of the cylinder 22 of a leading part 79 of the signature 78 by means of the puncture systems 26 each detected and a Vorfalz-clamping element system 28 of the Vorf a Izzy li nders 27 are supplied.
- Each signature 78, collected or not collected, is pushed into a pre-fold clamping gap 81 of the pre-fold clamping element system 28 by means of a folding knife 23 located on the cylinder 22.
- FIG. 2 shows a position D of the cylinders 22; 27, in which both the pre-folding clamping elements 31; 32 and the folding knife 23 have already passed through the center 56 by an angle of rotation alpha.
- the pre-fold clamping elements 31 close; 32 like pliers, or mouth-like, and form a pre-fold 83 on the signature 78.
- the pre-fold 83 is beyond an imaginary relaxation line of the two thickenings 46; 47 and within the two pre-fold clamping elements 31; 32 designed as a bead. Therefore, the prefabricated product 83; 79; 82 during further transport on the prefold 27 not from the closed prefold clamping elements 31; 32 slip out.
- the radius r of a thickening 46; 47 is smaller than the depth of penetration of a folding knife 23 into a pre-clamping clamp 81.
- Counterclockwise direction C is the non-essential pre-product between the two belt systems 63; 64 added.
- the belt systems 63 separate approximately a good half a turn of the prefolding cylinder 27 after the prefolding process; 64 from the prefabricated cylinder 27 (not shown in FIG. 1), the first belt system 63 the prefabricated product when the pre-clamping elements 31; 32 has just lifted out on its pre-fold 83 and subsequently both tape systems 63; 64 the preliminary product of the folding rollers 61; Feed 62 to finish folding.
- the advantages of pre-folding in two-stage cross folding are that due to the rounding of the peripheral parts of the pre-fold elements for the signature, a larger support distance between the folding knife and
- Pre-fold clamping element is present than in known jaw systems. Due to this larger support distance and the rounding of the peripheral parts, thick folded products can be inserted into the pre-fold clamping gap without damage and with less force than with conventional folding jaw systems.
- the rounded Vor alz clamping elements protect the outer layers of the folded product due to their large contact area. The inner layers of the folded product are protected by the fact that the folding knife can unwind via the rounded pre-fold clamping elements without jamming the pre-folded product.
- the punctures are additionally moved back into the pre-fold clamping gap by an amount of the penetration depth of the folding knife when retracting relative to the leading edge of the leading part of the signature.
- E Movement Direction (84, 86) a distance (47, 47; 46, 46) f width (84) g width (51) m number (28) n number (29) r radius (46; 47) t depth (67)
