Definitions

  • the present invention relates to a device for processing folded printed products according to the preamble of patent claim 1.
  • Such a processing device is usually part of a complex processing plant for the processing of printed products, the product flow through a conveyor device, for example, forming, stapling, addressing, collecting, cutting, labeling devices, etc. goes through.
  • a known device for collecting printed products is for example in the EP-A-0095603 described.
  • folded printed products are transported to their respective two product parts connecting fold held by grippers of a feed conveyor to a conveyor.
  • the conveyor device has successively oriented in a conveying direction and oriented transversely to the conveying direction support saddles, which are intended for rittlingweise recording of the printed products, on.
  • Before depositing the fold opposite open side edges of the printed products are supported on an opening conveyor lying in the direction of the support saddles.
  • a smaller conveyor belt adjoining the opening conveyor in a feed direction to the conveyor device then transports a free end area of a product part leading in the feed direction faster to the conveyor device than the free end area resting thereon still resting on the opening conveyor end of the trailing product part.
  • the distance between the upstream and downstream product part increases such that the printed product is opened and the leading product part comes into engagement in a leading in the conveying direction gap before the saddle and then the trailing product part in a trailing gap of the recording saddle for engagement.
  • the feed conveyor simultaneously promotes the falz character held printed products to the conveyor out, each one gripper partially carried with a support saddle and the printed product is released only from the gripper, if a safe placement of the printed product is guaranteed on the support saddle.
  • the trailing product parts resting on the opening conveyor can be retained at least in sections by means of holding devices attached to the opening conveyor.
  • this processing device For the feeding of a conveying device with printed products present in stacks, this processing device proves to be only conditionally suitable, since the printed products are transformed into an imbricated formation, individually grasped by the grippers and then placed in synchronized with the opening of the opening conveyor, the small conveyor belt and the conveying device ,
  • the opening of the product parts by means of the high-speed small conveyor belt at high conveying speeds is problematic because the product parts are transported freely on the small conveyor belt and thus influenced by the "wind".
  • the known processing device requires on Feed conveyor rotating grippers, the opening conveyor and the associated small conveyor belt a relatively high design control engineering effort.
  • Object of the present invention is therefore to provide a generic device for processing folded printed products, which allows a simple structure to store the folded printed products safely on a conveyor.
  • the inventive device for processing folded printed products has a conveying device, a feed conveyor and an opening device.
  • the feed conveyor thereby promotes the printed products with their respective two connected to a fold product parts of the opening device and optionally the conveyor to. With their open, opposite the fold side edge leading the printed products pass through the opening device and are there at least partially open before dropping on Auflages expediteln the conveyor.
  • the support saddles of the conveying device are arranged one behind the other in a conveying direction circumferentially and oriented transversely to the conveying direction. The paddles take up the open printed products astride.
  • the processing device is additionally provided with drive means, in particular a drive, equipped, which moves the opening device during an opening-pad operation at least almost in the conveying direction and in each case at least approximately opposite to the bearing saddle to be loaded (briefly also moved).
  • This movement is in each case synchronized with the clock with which the support saddles are guided past the opening device.
  • the movement leads to a relative velocity reduced in the conveying direction between, on the one hand, the opening member or the opened printed product and, on the other hand, the support saddle moved in the conveying direction.
  • a period of time for threading the product parts in intermediate spaces before or after the respective loading saddle is extended and thus ensures safe storage of the opened printed products on the possibly also moving at high speed Auflagesatteleln.
  • the secure storage of printed products in turn allows an uninterrupted processing flow and prevents the production of incomplete finished products. This, together with the relatively simple structural design of the processor, contributes to a reduction in the time and expense of processing the printed products.
  • the processing device 10 has a conveying device 12 shown in detail in FIG. 1, a feed conveyor 14 and an opening device 16.
  • the processing device 10 serves to reliably feed the conveying device 12 with folded printed products 18 that is conveying at high conveying speed in a conveying direction F.
  • the printed products 18 each have two product parts 22 connected to a fold 20. Opposite the fold 20, the printed products 18 have an open side edge 24. In the closed state of the printed products 18, inner sides 26 of the two product parts 22 lie flat against one another. In the partially opened state of a printed product shown in FIG. 1, the free end portions of the product parts 22 are spread apart at the open side edge 24.
  • a still closed part of the printed product 18 including the fold 20 is located in one formed by two conveyor belts 28 of the feed conveyor 14 Feed gap 30.
  • the conveyor belts 28 run in opposite directions of rotation U, U 'illustrated in FIG. 1 by arrows and thereby transport the product parts 22 in the conveying gap 30 with their outer sides 32 against the conveyor belts 28 in a feed direction Z to the conveyor device 12.
  • the conveyor belts 28 are wrapped on the conveyor device side about two rotatably mounted rollers 34 of the opening device 16 and drive them in their conveying movement.
  • the two rollers 34 are held spaced apart at their axes by a telescoping coupling rod 36 and form an opening gap 38 in continuation of the conveying gap 30.
  • One of the opening device 16 supplied by the feed conveyor 14 closed Druckereieck 18 is taken during or shortly after passing through the opening gap 38 at a Vorfalz 39 with respect to the conveying direction F trailing product part 22 of a arranged on the roller 34 and designed as jaws holding device 40 and against the roller 34 pressed. In this way, the trailing product part 22 is held vorfalzmann and adjacent to the roller 34 in the circumferential direction U circulated to open the printed product 18.
  • the holding device may alternatively be designed as a gripper or suction head.
  • a plurality of holding devices 40 may be formed on a roller 34 or on both rollers 34.
  • rollers 34 can also Conveyor rollers, around which the conveyor belts 28 are wound for conveying the printed products 18 fitting, may be arranged.
  • the conveyor rollers preferably sit non-rotatably on the shafts of the rollers 34.
  • the coupling rod 36 is designed in two parts.
  • the two coupling rod parts 36A and 36B are connected to each other via a tension spring 42 Federkraftbeetzschlagt. In this way, the distance between the rollers 34 and thereby the width of the conveying gap 30 and the opening gap 38 adapts to the material thickness of the printed product 18.
  • the feed conveyor 14 is mounted on a frame arm 48 via a stationary axle 44 of a small driven feed wheel 46 of a conveyor belt 28 in the manner of a pendulum.
  • a stationary mounted conveying wheel 46 with respect to the conveying gap 30 opposite further feed wheel 50 of the second conveyor belt 28 is correspondingly pendulum-like, so for small deflections at least approximately in the conveying direction F to the stationary axis 44 of the feed wheel 46 together with the remaining conveyor 12 and the opening device movable or deflectable.
  • the coupling rod 36 is articulated by a push rod 54 of a crank 56 designed as a drive.
  • the opening device 16 is moved in this way, together with the feed conveyor 14 at least almost along the conveying direction F back and forth.
  • the drive 56 has, in addition to the opening device side rotatably mounted on a lug 58 push rod 54 a rotating in a rotational direction D drive wheel 60.
  • a crank pin 62 is arranged, which engages slidably engaged in a slot 64 of the one side by means of a bearing shaft 66 pivotally mounted on the frame 48 tab 58.
  • the crank mechanism converts the rotary motion of the drive wheel 60 into a substantially reciprocating motion of the push rod 54.
  • the drive wheel 60 drives the feed wheel 46 of the feed conveyor 14 via a chain drive 61 drawn in a dash-dotted line in FIG.
  • the chain drive 61 can also be replaced by a belt drive or the conveyor wheels 46, 50 can be driven autonomously, for example by means of an electric motor.
  • Fig. 1 the solid lines of the opening device 16 and the feed conveyor 14, the position upon reaching a relative to the conveying direction F upstream first reversal point U1 on the circulation path of the crank pin 62.
  • the dotted lines show their position in the positioning of the crank pin 62 at one downstream second reversal point U2. Due to the larger in the direction of rotation D circulation path of the crank pin 62 from the reversal point U1 to the reversal point U2 the pendulum-like deflection of the opening device 16 is slower with the feed conveyor 14 than in the return movement in the opposite direction, in which the crank pin 62 from the reversal point U2 to the starting position at the reversal point U1 is turned.
  • a cylinder-piston arrangement or a linear drive can likewise be used.
  • the partially opened printed product 18, with its product part 22 leading in the conveying direction F engages in an intermediate space 68 leading in the conveying direction F to an immediately opposite support saddle 70.
  • four of the support saddles 70 which are substantially triangular in cross-section, are visible.
  • the support saddles 70 are moved in the conveying direction F by means not shown.
  • the conveyor device 12 may also be drum-shaped.
  • the support saddles 70 are oriented one behind the other and transversely, in particular at right angles to the conveying direction F.
  • support saddle 70 On the first in the conveying direction F support saddle 70 a printed product 18 is already stored. In this case, the inner sides 26 of the product parts 22 rest against the support saddle 70 and the fold 20 is positioned above an opening device-side support edge 72. The further movement sequence of the partially opened printed product shown in FIG. 1 for depositing on the support saddle 70 will be described in detail below with reference to FIGS. 2 to 7.
  • FIG. 2 shows a starting position of the opening device 16 or conveying device 12, in which the opening gap 38, including the conveying gap 30, is aligned essentially at right angles to the conveying direction F.
  • the printing product 18 to be deposited is located completely in the conveying gap 30.
  • Two leading support saddles 70 are already loaded with printed products 18.
  • the product part 22 following in the conveying direction F is deflected adjacent to the roller 34 in order to open the printed product 18 simultaneously with its end region opposite the fold 20 by means of the holding device 40 in the circumferential direction U, ie substantially counter to the conveying direction F.
  • the opening device 16 with the feed conveyor 14, thus also the feed direction Z is substantially in the conveying direction F with the moved along opposite support saddle 70. This ensures correct engagement of the free end regions of the product parts 22 leading in the feed direction Z on the one hand into the intermediate space 68 leading in the conveying direction F and on the other hand into a gap 69 trailing in the conveying direction F with respect to the support saddle 70 to be loaded.
  • the drive wheel 60 shown in Fig. 1 reaches its second reversal point U2 and the opening device 16 discharges the now fully opened printed product 18 from the opening gap 38, which then comes to rest on the support saddle 70.
  • the opening device 16 together with the feed conveyor 14 is again moved back against the conveying direction F in order to again reach the starting position shown in FIG. 2.
  • the printed product 18, which has now been retracted into the conveying gap 30 and advanced in advance in the feed direction Z with the open side edge 24, is brought up to the opening gap 38.
  • the stored printed product 18 is then transported along with the other Auflages decisivteln 70 in the conveying direction F.
  • the inventive processing device 10 is suitable for processing printed products 18 not only at high conveying speeds.
  • the relative speed in the conveying direction F is reduced with respect to the support saddles 70 and thereby extends the transfer time for the laying of the printed products 18. This ensures that the storage of a printed product 18 takes place exactly on a support saddle 70 and that erroneous insertion of the printed products 18 into leading or trailing gaps 68, 69 is avoided. Due to the small distance between the opening gap 38 and the support edges 72 of the support saddles 70, the printed products 18 do not pass through only very short distances until they are completely deposited on the support saddles 70.
  • the inventive processing device 10 is also characterized by a comparatively simple and thus cost-effective to manufacture and maintain construction, in particular of the feed conveyor 14 from.
  • a processing device 10 according to the invention can additionally be equipped with further opening device feed conveyor units which simultaneously store printed products 18 individually on a common conveyor device 12.
  • a plurality of support saddles 70 can be charged simultaneously or with a plurality of printed products 18 stacked one above the other.
  • the movements of the feed conveyor 14, the opening device 16 and the conveyor 12 are controlled synchronized by a control device, not shown.
  • This control device ensures that in the storage of the printed products 18 each of the opening gap 38 is at least partially moved with the opposite support saddle 70 in the conveying direction F.
