Definitions

  • the invention relates to a device for the adhesive attachment of inserts to the free-standing surface of printed sheets transported by a conveyor device of a processing machine, by means of a conveyor which removes the inserts individually from an insert formation and which has a driver arrangement which detects the inserts.
  • a generic device is known from EP-A-0 606 550.
  • Flat products are fed between two superimposed conveyor belts, driven in the same direction and at the same speed, to a takeover area, where they are taken over by a transfer conveyor below the upper longer conveyor belt, which has controllable clamps articulated on a wheel-like support member.
  • the brackets are controlled in such a way that the products in the takeover area are picked up at the trailing edge after the products have been collected.
  • the products are glued to the printed sheets on the flanks of the saddle-shaped webs by swiveling the clamps.
  • the adhesive is applied in front of the takeover area of the products by the transfer conveyor.
  • This known device is structurally complex and the functions performed when conveying the products as well as the arrangement and design of the individual processing components do not ensure smooth processing. Specifically, this means that the feeding of the products requires a preliminary separation and a section of the path on which the products pass through a glue application station. The applied glue settles on the affected conveying bodies and from there on the subsequent products. Moreover, the pushing locomotion of the products may prove to be a difficult undertaking due to their instability in the production channel.
  • the object of the invention is to create a device of the type mentioned at the outset which permits reliable processing of flat products or supplements with simpler equipment.
  • this object is achieved in that the driver arrangement is driven by a clock-driven, adhesive device which takes over the inserts from the driver arrangement is coupled, which is connected to a control device causing the adhesive movement.
  • a control device causing the adhesive movement.
  • the device according to the invention is suitable for a saddle stitcher as well as for a collating device or an inserting machine.
  • the device proves to be advantageous for saddle stitching with supports running longitudinally and transversely in the direction of conveyance for the astride recording of printed sheets or printed products; likewise in the case of a collating machine in which the printed sheets are collected in a conveying channel lying one on top of the other or standing against one another and transported transversely to the conveying direction, and in a plug-in machine in which the printed sheets are collected in bag-like containers; the device can optionally be adjusted by 90 ° on a vertical axis above the conveyor.
  • a facility of the beginning proves to be particularly favorable mentioned type, if the conveyor is designed as a rotating drum, in which the driver arrangement for detecting the individually transported inserts is arranged on the circumference, so that the inserts can be processed from a scale or stack formation.
  • FIG. 1 and 2 show a device 1 for attaching supplements 2 by gluing to the free-standing surface of folded printed sheets 4 lying astride on a conveying device 3 of a processing machine, in which the supplements 2 are provided with a rotatingly driven drum conveyor 5 which has a circumference Driver arrangement has to be supplied.
  • the supplements 2 are placed one on top of the other in a magazine 6 arranged above the drum conveyor 5.
  • a suction device 7 By means of a suction device 7, the lowest insert 2 in each case is lifted from the rest of the stack in the magazine 6 in the vicinity of the fold edge, so that it can be gripped by the driver arrangement of the drum conveyor 5 rotating in the direction of the arrow F after the pivoting out of a support device 9.
  • the driver arrangement distributed on the circumference of the drum conveyor 5 attached gripping devices 8, which the inserts in the edge or. Take over the folding area by clamping and transfer it to an adhesive device 10 which is coupled in a clocked manner to the rotating gripping devices 8 or the driver arrangement.
  • the conveying device 3 consists of a plurality of support webs 11, which follow one another at intervals one after the other, transversely to the conveying direction P, on a rotating traction means, not shown.
  • the support webs 11 formed with a support saddle rise in the effective range of the gluing device 10 from its approximately horizontal running direction and exert a swiveling movement so that the insert 2 can be inserted without interference between two support webs 11 and can be attached on the back to the printed sheet 4 resting on the front support web 11 in the running direction.
  • the gluing device 10 is designed to be pivotable about at least one axis parallel to the axis of rotation 12 of the drum conveyor 5 arranged at right angles to the running direction P of the conveying device 3 and has a holding device 13 for the inserts 2 to be taken over by the gripping devices 8.
  • the gluing device 10 has one side of the drum conveyor 5 arranged control device 14 in connection.
  • the end of the gluing device 10 opposite that of a holding device 13 for the inserts 2 is pivotably connected to the rotating end of a drive crank 15 of the control device 14.
  • the drive crank 15 is driven in rotation by means of a push rod 17 of a crank mechanism 18 about an axis 16 parallel to the pivot axis of the gluing device 10, the crank mechanism 18 being coupled to the drum conveyor 5 via a two-wheel toothed belt transmission 19.
  • the embodiment angled by approximately 90 ° between the connection point on the drive crank 15 and the holding device 13 of the adhesive device 10 has an intermediate pivot axis 20, which is formed by a fixedly arranged link 21. The latter is pivotally suspended in a bearing and the pivotable end forms a pivot axis 20 of the gluing device 10.
  • the gluing device 10 formed by pressing arms 22 is on the way to the gluing position with an insert 2, which is represented by dash-dotted lines.
  • the takeover position is in Fig. 1 at about 5 o'clock.
  • the inserts 2 pass through an adhesive application station 24, which is positioned on the trajectory of the inserts 2 transported by the drum conveyor 5, that is to say that in the exemplary embodiment illustrated, the adhesive on the inserts 2 during transport through the gripping devices 8 - preferably in the edge area - is applied in strips or dots. Due to the arrangement and design of the control device 14, the pressing arms 22 of the gluing device 10 do not perform a uniform geometric or regular movement, especially since the inserts 2 are immersed between two support webs 11 bearing a printed sheet in narrow spatial relationships.
  • Fig. 2 illustrates the design of the device 1 and the interaction and the union of the drum conveyor 5 with the gluing device 10 and the control device 14 on one side.
  • a frame 25 is provided for mounting the device 1, in which a driven main shaft 26 is mounted.
  • a conveyor rotor 27 is attached, which is provided with three gripping devices 8 which are distributed around the circumference and which grip the insert 2 after it has passed through the suction cups 29 attached to a suction shaft 28 pivotally mounted in the frame 25 have been partially lifted from the underside of the stack of inserts located in the magazine 6.
  • Two toothed belt wheels 30, 31 form a toothed belt countershaft 32, through which the control device 14 and the gluing device 10 are driven synchronously with the drum conveyor 5.
  • a crank disk 34 mounted in the frame 25 by means of a shaft 33 transmits the rotational movement to the push rod 17, which controls the adhesive movement of the adhesive device 10 mounted on the handlebar 21.
  • the double tax effective hanging device 10 is mounted on the one hand on the drive crank 15 driven by the push rod 17 and on the handlebar 21, so that overlapping movements occur on the sticking device 10, which lead to favorable adhesive conditions between two support webs 11.
  • the support webs 11 are designed to be movable and controllable, so that they can adapt to the narrow conditions and the movements of the adhesive device 10 in a suitable manner.
  • the deflection of the support webs 11 on the conveying device 3 is adjustable, as are the movements of the adhesive device 10 in coordination with the format size of an insert 2.
  • the device 1 according to the invention is suitable not only for conveying devices 3 of a saddle stitcher forming a collecting section, in which the printed sheets 4 are transported lengthwise or transversely to the conveying direction, but also in known collating devices or. Gathering machines of a perfect binder or thread stapler, the printed sheets lying on top of one another as well as against each other through the The present device 1 can be loaded with an adhesive insert 2. It is irrelevant whether the collating device is connected upstream of the binder or integrated into it.
