Definitions

  • the present invention relates to an apparatus for wire stitching multi-part printed products.
  • DE-A-32 03 376 describes a stapling device in which the products to be stapled are passed between respectively cooperating staple-setting elements and staple bending elements.
  • the clamp setting elements and the clamp bending elements are each fastened to an endless, continuously driven chain, one strand of which runs parallel to the direction of movement of the products and adjacent to the path of movement of the latter.
  • the staple setting elements and the staple bending elements opposite the latter during the stapling process run synchronously with the products during stapling.
  • a further concentricity is provided, which is formed by patrices attached to an endless, rotating chain.
  • a wire section dispenser is arranged on the orbit of these patrices, which dispenses a straight piece of wire to the patrix passing by. The latter is bent when a patrix meets a clamp-setting element acting as a matrix to form a U-shaped clamp, which is transported from the clamp-setting element to the stitching area and pressed into a product there.
  • This stapling device is of relatively complex construction, since three round runs are necessary, namely one for the patrices feeding the straight wire pieces, one for the clip-setting elements which cooperate with the latter to form the clips and press the clips into the products, and one for the clip bending elements. Furthermore, the brackets are set to the direction along the direction of movement of the products.
  • US-A-4,792,077 describes a simplified embodiment of the device explained above, in which only two chain runs are provided.
  • the chains of the concentric runs are guided over deflection wheels and lie opposite each other with a section lying between the deflection wheels.
  • the chain of a chain run runs past a wire section dispenser, with certain chain links being handed over straight wire sections which extend in the direction of rotation of the chain.
  • the products to be stacked are fed to the two chain circuits by means of a feed conveyor and are introduced between the two opposite sections of the two chain circuits.
  • the products are then transported further by clamping between the links of the two chain circuits. The latter thus take on the double task of setting the wire clamps and forward transport.
  • the wire clips are placed along these fold lines in the longitudinal direction of the products. If a product is provided with two clips, the wire clips for a product are set one after the other.
  • the present invention has for its object to provide a device for wire stitching of multi-part printed products that enables reliable and flawless stitching of the products with a simple construction.
  • FIG. 1 shows a collecting drum 10, as described in detail in EP-A-0 341 425.
  • This collecting drum 10 has a common saddle-shaped supports 14 arranged around the axis of rotation 12, extending in the direction of the axis of rotation 12 and driven in the direction of rotation U.
  • a carriage 16 which can be moved back and forth in the direction of the rotational axis 12 is provided with a controllable clamping arrangement 18 for the folded printed sheets 20 straddling the supports 14.
  • a stapling station 22 has a stapling head arrangement 24 with stapling heads 28 arranged one behind the other along a movement path 26 coaxially around the collecting drum 10.
  • a stapling head 28 is assigned to each support 14, which are thus arranged essentially at the same mutual distance A as the supports 14.

  • This wire section dispenser 30 has a cutting device 32, by means of which wire sections 38 are separated from a wire 36 drawn off from a supply roll 34. Downstream of the cutting device 32 is a magazine 40 fed by the cutting device 32 with wire sections 38.
  • the device shown in FIG. 1 operates as follows: seen in the conveying direction of the carriage 16, the stapling station 22 is preceded by feed stations for printed sheets in a known manner. These feed stations each place a folded printed sheet 20 astride each support 14 passing in the direction of rotation U at the feed station. Before in each case a support 14 runs into the lower region of its circular movement path, the relevant clamping arrangement 18 is clamped in order to hold the parts of the printed sheets 20 which extend into the corresponding carriage 16. In the course of passing through the lower half of the path of movement of the supports 14, the carriages 16 make a working stroke in the longitudinal direction of the axis of rotation 12 to the next feed station or to the stapling station 22.
  • the stitching heads 28 are also driven in the direction of rotation U in synchronism with the supports 14.
  • a stapling head 28 runs past the feed wheel 42, it takes over a wire section 38 from the feed wheel 42.
  • the wire section 38 now held by the stapling head 28 is formed into a clamp, as is the case here will be described in detail below.
  • the clip is brought from the outside of the stitching heads 28, as seen in the radial direction, to the inner side facing the supports 14.
  • the relevant stitching heads 28 are placed on the printing sheets 20 placed one above the other on the supports 14 lowered and the clamps inserted into the printed sheets.
  • the distance A of the stapling heads 28 corresponds to the spacing of the support 14. After the staples have been placed, the stapling heads 28 are raised again, after which the collected and stapled printed sheets 20 are fed to a removal station in the course of the next rotation of the collecting drum 10 in the direction of the rotational axis 12 will.
  • the collecting drum 10 shown in FIGS. 2 and 3 corresponds to that of FIG. 1 and is therefore no longer described in detail.
  • the movement path 26 for the stitching heads 28 is kidney-shaped and runs in an area D along the orbit of the supports 14 of the collecting drum 10.
  • the collecting drum 10 is arranged outside the movement path 26 and the wire section dispenser 30, which is only indicated schematically, is arranged inside the latter.
  • the collecting drum 10 rotates counterclockwise U and the stitching heads 28 are driven in the opposite direction U 'at the same speed as that of the pads 14.
  • the distance A of the stapling heads 28 corresponds in turn to the spacing of the supports 14 when the staples are set, so that in the area D for setting the staples a corresponding stapling head 28 runs with each support.
  • FIG. 3 corresponds essentially to that of FIG. 2.
  • the movement path 26 is circular and the area D is essentially shortened to a point D '.
  • the respective stitching head 28 comes into contact only very briefly with the staple in the printed sheets 20 deposited on the supports 14.
  • the stitching heads 28 are arranged along their movement path 26 at a distance A which, when the staples are set, corresponds to the distance between the supports 14 Collection drum 10 corresponds.

  • This has a pulling element 50 which is guided around two spaced-apart deflection wheels, indicated only with their essentially horizontal axes of rotation 48, on which supports 14 are arranged at certain intervals one behind the other, parallel to one another and at right angles to the direction of rotation U.
  • the stapling station 22 has a stapling head arrangement 24 arranged above the collecting conveyor 46 with an elongated movement path 26 for the stapling heads 28.
  • the stitching heads 28 are arranged on a pulling element, not shown, with the same spacing A as the supports 14 in the area D.
  • the traction element is driven in the direction U 'at the same speed as the traction element 50 in the direction U.
  • the stitching heads 28 thus run in the area D synchronously with the supports 14 and move past the wire section dispenser 30 remote from the area D.

Of course, the stapling station 22 is followed by an exit station for the stapled printed sheets 20.
  • the stapling stations 22 shown in FIGS. 2 to 4 function as follows: Each stapling head 28 takes over a wire section from the wire section dispenser 30 as it passes by. In the course of the circular movement in the direction of the arrow U 'along the movement path 26, a clip is bent from the wire section in the area between the wire section dispenser 30 and the area D, D' (staple setting area) and this is placed on the side of the stitching heads 28 that is outside the movement path 26 .

  • the bending machine 206 is also pivoted back into its original position.
  • the actuating shaft 100 is released by the clamping lever 94, which causes the stamp 130 to pivot back into the rest position.
  • FIGS. 16 and 17 the drant section dispensers 30 indicated in FIG. 5 and assigned to the two stitching head arrangements 24 are shown enlarged.
  • Each of these wire section dispensers 30 is constructed in the same way as the wire section dispenser 30 shown in FIG. 1.
  • the cutting device 32 is driven by a rotating toothed belt 208.
  • a pair of conveyor rollers 210 conveys the wire 36 clamped between them step by step in the direction of the arrow H.
  • a cutting knife 212 which can be moved up and down in the direction of the arrow I separates a wire section 38 from the wire 36 by lowering after each conveying movement of the wire 36.
  • the magazine 40 is arranged downstream of the cutting knife 212 below the cutting device 32. It has an essentially slit-shaped stacking shaft 214 running approximately in the vertical direction, in which the wire sections 38 falling therein can be stacked one above the other with a longitudinal extension running essentially in the horizontal direction.
  • a pre-stacking device 216 with a tongue 218 which can be moved into the area of the stacking shaft 214 and can be withdrawn from it.
  • a number of wire sections 38 separated from the wire 36 by means of the cutting device 32 are stacked.
  • these stacked wire sections 38 then fall together into the stacking shaft 214. This prevents the wire sections 38 from being erected and tilted during the free fall and guarantees a clean stacking of the wire sections 38 in the stacking shaft 214.
  • the two conveyor wheels 42 arranged below the magazines 40 are seated in a rotationally fixed manner on a common bearing shaft 224 which is rotatably mounted on a pair of support levers 222.
  • the two are by a drive device 228 acting on the bearing shaft 224 via a drive belt 226 Conveyor wheels 42 driven in the direction of arrow V.
  • Each conveyor wheel 42 has two parallel disks 230 spaced apart from one another, between which the holding members 44 are arranged along the circumference at specific intervals.
  • the holding members are U-shaped and have at their free ends which are directed outward in the radial direction over the periphery of the disks 230, protruding flanks 232.
  • a permanent magnet arrangement is provided on the holding members 44 in order to hold the wire sections 38 detached from the stacking shaft 214 by the driver flanks 232 as they pass the magazine 40.
  • the stitching heads 28 are spaced further apart than the holding members 44. Accordingly, the peripheral speed of the feed wheels 42 is lower than the rotational speed of the stitching heads 28, so that the next stitching head 28 meets the next holding member 44.
  • the stapling head 28 thus runs past the holding member 44 and, with the driver lugs 138 arranged on the punch arms 128, pulls the relevant wire section 38 from the holding member 44 and holds it to the punch 130 by means of the permanent magnets 140.
  • the holding members 44 are arranged in a generally known manner to be displaceable and spring-loaded in the radial direction in order to be able to take up tolerances and to ensure a secure transfer of the wire sections 38 from the stacking shaft 214 and transfer to the stitching heads 28.
  • the initial region of the driver link 92 is shown in FIG.
  • the follower rollers 86 of the drivers 82 run onto the driver link 92, which has the consequence that the drivers 82, which are guided on the holding part 68 in a radial direction, are lowered onto the relevant supports 14 of the collecting drum 10.
  • the V-shaped driver profiles 84 encompass the supports 14. This has the consequence that the stitching heads 28 arranged on the support profile 62 and not shown in FIG. 18 are precisely aligned with respect to the assigned support 14 or the printed sheets 20 placed thereon.
  • the drive of the holding arrangement 52 takes place exclusively by being carried along by the catches 82 which are in engagement with the supports 14.
  • the catches 82 are lowered onto the supports 14 only in the upper region of the orbit of the collecting drum 10, so that the means of the The stapling station 22 can staple the printed sheets 20 in the direction of the axis of rotation 12 through the supports 14 and driver profiles 84 which are now spaced apart from one another, or that the printed sheets 20 to be stapled can be brought into the area of the stapling station 22.
  • a stitching head 28 is now traced in the course of one revolution of the holding arrangement 52, starting at the wire section dispenser 30.
  • the stitching heads 28 pass the wire section dispenser, they are in their outer rest position, seen in the radial direction, in which they are spaced apart from the supports 14.
  • the punches 130 are pivoted back into the rest position, so that the free ends of the punch arms 128 are directed towards the outside, as seen in the radial direction.
  • the stapling head 28 runs past the relevant holding member 44 of the feed wheel 42, the wire section 38 fed from the holding member 44 is detached from it by the driving lugs 138 and taken along (FIG. 19).
  • the stitching heads 28 reach the area of the die 98, as shown in FIG. 20. Seen in the direction of arrow U, the distance between the link-shaped die 8 and the shaft 120 is reduced, so that when the punch 130 is in the rest position, the wire section 38 in question is bent into a bracket 104 and pushed into the grooves 136 of the punch arms 128 (FIG. 20).
  • the slide shoe 200 runs onto it, which has the consequence that the actuating shaft 100 is pressed inward in the direction of arrow F in the radial direction. This translational movement of the actuating shaft 100 is converted into a pivoting movement of the shaft 120 via the pinion 190.
  • the support part 118 comes with its pressing lugs 170 on the printed sheets 20 astride the pads 14 to the system. It should be noted that the pressing noses 170 hold the printed sheets 20, in the direction of the support 14, in front of and behind the clip 104 and on both sides thereof, which leads to a particularly clean stitching. It should also be noted that the support part 118 is displaced with respect to the bearing arrangement 172 fixed to the support profile 62 depending on the thickness of the printed sheets 20. This ensures clean stitching of sheets 20 of different thicknesses without the device having to be readjusted (cf. FIG. 22).
  • the plunger 80 slides back into its outer rest position, as seen in the radial direction, under the action of the compression spring 166 and the distance from the supporting part 118 which increases in the end region of the plunger link 78.
  • the stitching heads 28 are now ready to accept a new wire from the wire section dispenser 30.
  • the collecting drum 10 continues to rotate, the stapled printed sheets 20 are now fed in the direction of the axis of rotation 12 from the area of the stapling station 22 to an exit station (not shown).
  • the wire section preparation By separating the wire section preparation from the stitching heads 28, these can be constructed very simply. Moreover, only a single wire section dispenser 30 is required per stitching head arrangement 24, which reduces the expenditure to a minimum. In addition, the wire section dispenser 30 can be removed from the area in which the clips 104 are placed in the printed sheets 20. As a result, there is sufficient time for the preparation of the clips 104 in the area between the wire section dispenser 30 and the clip setting area. In the case of stapling heads with pivotable stamps 130, the staples 104 can be prepared in a position different from the staple setting position 130 ', which means that the various functions of the stapling heads 28 are spatially separated from one another; this in turn has the consequence that the stitching heads 28 are simply constructed with small dimensions.
  • the die can be provided for bending the wire section 38 into a clamp 104 on each stitching head 28 itself.
  • This has an eccentric shape to the shaft, so that in the course of the pivoting movement of the plunger 130, the clamp 104 is formed from its rest position into the clamp setting position 130 '.
  • Such a matrix could be formed on the clamp holding member 146 in a clockwise direction, in particular as an extension thereof.
  • the drivers it is of course also possible for the drivers to be arranged on the stitching heads. So it is quite conceivable that the pressing lugs 170 serve as drivers. A separate drive for the stapling station 22 is no longer necessary and synchronization problems between the rotation of the collecting drum 10 and the stapling head arrangements 24 have been eliminated.
  • the traction element or the holding arrangement 52 can be driven in a rotating manner by means of its own drive motor. It is also conceivable that the wire section dispenser has an interchangeable magazine or that the wire sections are fed directly from the cutting device to the stitching heads.
  • the stamps 130 can be in a wire transfer position that is different from the rest position for the wire transfer.
  • the wire takeover position does not correspond to the clamp setting position 130 '.
  • the wire sections 38 run essentially parallel to the pivot axis 122.
  • stapling stations 22 of the devices according to FIGS. 2-4 are constructed similarly to the stapling station 22 described above in connection with the device according to FIG. 1.
  • Stapling heads which are particularly suitable for devices according to the invention for wire-stitching printed products are described in EP-A-0 399 322.
  • a stitching head in which a stitching head is permanently assigned to each support, also allow the stitching heads of a stitching head arrangement to be mutually offset in the longitudinal direction of the supports. For example, every second stitching head can be slightly offset with respect to the other stitching heads arranged in one plane.
  • the two groups of stitching heads then advantageously each pass their own wire section dispenser. When stapling the stapled sheets, not all of the staples come to lie on top of one another.
