Definitions

  • the present invention relates to a device for wire stitching multi-sheet printed products, which has the features in the preamble of claim 1.
  • a device of this type is known from US-A-3,762,622. It has a wire section dispenser with a wire guide for a step-by-step stitching wire.
  • a cutting element downstream of the wire guide, seen in the feed direction of the stitching wire is lever-shaped, driven to rotate about an axis running parallel to the feed direction of the stitching wire, and has driving teeth on its radial end, which strike the advanced starting area of the stitching wire and act together in cooperation with a fixed knife Separate the wire section from the stitching wire.
  • the wire section is arranged between the radial end of the cutting element and a quarter-circular guide element, is carried along by the driving teeth by approximately 90 ° and is fed to a holding device.
  • the holding device has a first holding element designed as a leaf spring and a fixed second holding element designed as a block, which tangentially adjoins the orbit of the driving teeth and which has a longitudinal extension perpendicular to the wire section, into which the wire section is inserted while sliding off the driving teeth. It is held there under the spring action of the first holding element.
  • a rotating stitching head shows Driving element with a driving flank, which strikes the wire section as it moves past the gap and conveys this out of the gap which is open downstream in the direction of movement of the driving element.
  • the gap is followed by a wheel-like, rotating bending element which is intended to force the wire section entrained by the entrainment member into a staple guide of the stapling head, at the same time being formed into a staple.
  • the holding elements can be moved relative to one another from a rest position into a clamping position narrowing the gap and back again.
  • This enables the stitching wire to be advanced into the gap in a direction transverse to the longitudinal direction of the gap and the direction of movement of the entrainment member.
  • the stitching wire can thus be inserted directly from the wire guide into the gap. Since the wire section is held in each case by the holding elements, it can be separated from the stitching wire before the stitching head comes into contact with the wire section with its driving element. On the one hand, this minimizes the number of impacts on the stitching head and, on the other hand, the wire can be cut independently of the stitching head with optimal movement.
  • the device for wire stitching of multi-sheet printed products 10 shown in FIG. 1 and partially in FIG. 2 has a stitching head carrier 12 with double-walled carrier disks 16 seated on a carrier shaft 14 driven in the direction of rotation D. Only one wall of a carrier disk 16 is shown in the figures. Inside the carrier disks 16 there are stitching heads 18 distributed in a star shape, the housings 20 of which are pivotably mounted in the wall of the carrier disks 16 by means of pins 22. The housings 20 are eccentrically penetrated by a hinge axis 24 with respect to the pins 22, the ends of which are guided in endless, self-contained control grooves for determining the pivoting position of the stitching heads 18.
  • a staple guide 26 is mounted in and against the direction of arrow 28 to a limited extent in each housing 20 and is spring-loaded in the direction of arrow 28. At its radially outer free end region, it has a fork formed by legs 30, see also FIGS. 6 to 8.
  • the legs 30 have V-shaped end surfaces 32, 32 'at their ends, of which the end surface 32, which is the rear in the direction of rotation D, has forms a flank-like entrainment member 34. This is intended when walking past at a takeover point 36 of a wire section dispenser 38 to come to a wire section 40 and take it with them.
  • the stitching head 18 is in such a rotational position as it moves past the takeover point 36 that the entrainment member 34 extends approximately in the radial direction.
  • the wire section 40 is pushed into the crotch of the staple guide 26 with a simultaneous bending to a staple 44 using a backdrop-like bending element 42 downstream of the takeover point 36 in the direction of rotation D, the two staple legs 46 of the staple 44 being arranged in the inner side walls of the legs 30, longitudinal guide grooves come to rest.
  • a plunger 48 is also slidably mounted in and against the direction of the arrow 28, which carries at its radially inner end a follower roller 52 cooperating with a control link 50.
  • a collecting drum 54 of a known type has wall elements 56 arranged around an axis of rotation (not shown) which runs parallel to the support shaft 14 and whose radially outer ends form saddle-shaped supports 58 which run parallel to the axis of rotation.
  • the printed products 10 are placed astride one another on these supports 58.
  • the orbit 60 of the supports 58 driven in the direction of rotation U and the trajectory 62 of the centering projections of the staple guide 26 formed by the end faces 32, 32 'intersect.
  • the swivel position of the stitching heads 18 is controlled such that the staple guides 26 with the template meet with their end faces 32, 32 'with the supports 58 and leave them with a reserve, so that the clamp guides 26 and wall elements 56 are at least approximately in a radial to the axis of rotation of the collecting drum 54 during the interaction.
  • the staple guides 26 and supports 58 meet, the end surfaces 32, 32 'of the former come into contact with a multi-sheet printed product 10, press this against the support 58 under spring force and are in turn displaced inwards with respect to the carrier shaft 14, as a result of which the respective following roller 52 arrives at the corresponding control link 50 to the system.
  • the plunger 48 presses the staple 44 out of the stapling head carrier 12 and with its staple legs 46 through the printed product 10, after which the staple legs 46 are closed by means of benders arranged in the wall elements 56.
  • the wire section dispenser 38 at the takeover point 36 has a holding device 64, which is intended to hold a wire section 40 separated from a stitching wire 66 advanced in the feed direction V.
  • This passes through a gap 70, which is comprised of a tongue-shaped first holding element 72 and a second holding element pivotably mounted about a bearing axis 74 running parallel to the support shaft 14 76 is limited.
  • the longitudinal direction of the gap 70 runs essentially at right angles to the wire section 40 and thus in the direction of rotation D, and the entrainment members 34 each pass through a gap surface defined by the gap 70; in other words, the gap area and the flight path 62 of the entrainment members 34 essentially coincide.
  • the held wire section 40 protrudes with its two end areas 78 from the gap 70 over the side edges thereof and is thus exposed in some areas.
  • the width of the holding elements 72, 76 is smaller than the distance between the legs 30 of the staple guide 26, so that the staple guide 26, encompassing the holding device 64, can move past it.
  • the first and the second holding element 72, 76 engage in the crotch of the staple guide 26.
  • the legs 30 of the staple guide 26 lie symmetrically to a central plane 64 ′ running perpendicular to the carrier shaft 14 through the holding device 64. This central plane 64 ′ lies in the center of the wire section dispenser 38.
  • the spring tongue-like first holding element 72 is arranged with respect to the gap 70 on the side facing the carrier shaft 14 and, viewed in the direction of rotation D, is fastened upstream to a holder 80 with respect to the takeover point 36, compare in particular FIG. 2.
  • This holder 80 is attached to plate-shaped wall elements 82 of the Wire section dispenser 38 is pivotally mounted about an axis 84 parallel to the carrier shaft 14 and can be adjusted in its exact pivot position by means of an adjusting screw 86.
  • the free end of the first holding element 72 is in the direction of rotation D arranged downstream of the takeover point 36 and at the same time defines the end of the gap 70, which is thus open downstream and laterally.
  • the second holding element 76 which is mounted downstream with respect to the takeover point 36, is bifurcated at its free end and is penetrated by a shaft 90 between its prongs 88. This is arranged at one end of a two-armed actuating lever 92, whereby the second holding element 76 from a rest position 94 indicated by dash-dotted lines in FIG. 4 into a clamping position 94 ′ and shown in solid lines in FIGS. 2 and 6 and in FIG. 4 can be pivoted back again.
  • the gap 70 In the clamped position 94 ', the gap 70 is narrowed at the takeover point 36 in such a way that the wire section 40 is held securely, but can be taken along by the entrainment members 34 without bending by overcoming the holding force.
  • the gap 70 widens like a wedge downstream from the takeover point 36, so that the holding force decreases rapidly, but the wire section 40 is held in contact with the entrainment member 34.
  • the two holding elements 72, 76 are spaced apart from one another by a multiple of the diameter of the stitching wire 66, so that, with its end 66 'leading in the direction of advance V, it is secure from the side into the gap 70 between the holding elements 72, 76 can run in.
  • the stitching wire 66 is not lying exactly in the gap surface by means of a wire guide 96, but at an acute angle to it, fed in such a way that the leading end 66 'of the stitching wire 66 hits the first holding element 72 in the gap 70 and is slightly deflected by the latter.
  • the exit opening 98 of the wire guide 96 is thus set back with respect to the first holding element 72 on the side facing away from the carrier shaft 14 and on the side facing a cutting element 100.
  • the disk-like cutting element 100 can be moved from a feed position 101, in which the exit opening 98 is exposed, in the cutting direction S into a cutting position 101 'shown in solid lines in FIGS. 4 and 6 and back again.
  • the cutting element 100 is moved past the exit opening 98 which opposes the stitching wire 66, which leads to the severing of the stitching wire 66 and that in the cutting direction S after the corresponding end region 78 of the wire section 40 has been pushed forward.
  • the wire section 40 is subsequently straight again despite the oblique feeding of the stitching wire 66 with respect to the gap 70.
  • the outlet opening 98 is arranged in a screw shaft-like setting element 102 which is threaded into a support element 104 which is L-shaped in cross section.
  • the axis of rotation of the support element 104 runs parallel to the gap surface.
  • the adjusting member 102 is concave, so that the end of the wire section 40 facing the adjusting member 102 is exposed after the stitching wire 66 has been severed, and the corresponding end region 78 can move into the straight line.
  • this is on Cutting element 100 can be moved toward or away from it. As a result, it can be adjusted precisely to the end face of the cutting element 100 facing it, which leads to an extremely clean cut.
  • the support element 104 has a slot 106 opening into the opening receiving the adjusting member, which slot can be narrowed by means of a screw 108 to fix the adjusting member 102.
  • the passage 98 'in the setting member 102 is seen in the feed direction V, tapered close to the exit opening 98.
  • a guide tube 110 ends, adjacent to the passage 98 ′, offset and directed obliquely with respect to the axis of the setting element 102 in accordance with the oblique feed of the stitching wire 66.
  • the guide tube 110 is inserted into a through opening in the holding plate 112, the holding plate having a slot 106 'which extends through the through opening and which can be narrowed by means of a screw 108' for clamping the guide tube 110.
  • the holding plate 112 is exchangeably fastened to the support element 104 in order, if necessary, to be able to adapt the direction of the stitching wire 66.
  • the disk-like cutting element 100 is fastened to one end of the shaft 90, which is gripped by the second holding element 76 in a fork-like manner.
  • This shaft 90 is arranged on a lever arm of the two-armed actuating lever 92 pivotably mounted on the support element 104, on the other lever arm of which a follower roller 116 is freely rotatably mounted.
  • the axis of rotation 114 of the transmission lever 92 runs parallel to the carrier shaft 14, parallel to the shaft 90 and perpendicular to the central plane 64 '.
  • the actuating lever 92 is pretensioned by means of a compression spring 118 acting between the supporting element 104 and the lever arm carrying the follower roller 116 such that when the follower roller 116 is free, the cutting element 100 is in the feed position 101 indicated by dash-dotted lines in FIG. 4.
  • the follower roller 116 interacts with an actuating link 120, which is formed by the outer surface of a control disk 122 fastened to the carrier disk 116. As can be seen in FIGS. 1, 2 and 4, it has a radius increase per stitching head 18 and then a radius reduction, so that the cutting element 100 and the holding device 64 are actuated precisely in synchronization with the movement of the stitching heads 18.
  • the stitching wire 66 is advanced by a certain length by means of a schematically indicated feed device 124 and thereby inserted into the gap 70.

  • the actuating lever 92 is fork-shaped in the end region facing the shaft 90, the second holding element 76 engaging in the recess 130 formed thereby and engaging around the shaft 90 there.
  • the recess 130 is larger in the direction of the shaft 90 than the second holding element 76 in this area. This makes it possible to move the support element 104 together with the actuating lever 92, the cutting element 100 mounted thereon and the wire guide 96 in the direction of the shaft 90 and thus parallel to the carrier shaft 14. If these parts are arranged as shown in FIGS. 5 and 6, namely in this way that the cutting element 100 is at a minimal distance from the central plane 64 'of the wire section dispenser 38, short wire sections 40 are processed, so that the staples 44 formed have short clip legs 46.
