Definitions

  • the present invention relates to a method and a device for opening folded printed products, in particular newspapers, magazines and parts thereof, according to the preamble of claims 1 and 7, respectively.
  • the upper part of the product has an edge section in the end region, which protrudes beyond the shorter, lower part of the product.
  • This edge section is gripped by a gripper of the opening device and clamped between itself and the belt, and the shorter, lower part of the product is moved in the direction of conveyance by the faster running small conveyor belt moved away from the held part of the product with bulging and thus opened the printed product.
  • a collecting bar of a collecting device runs into the opened printed product between the separated parts of the product and after the release of the printed products by the transport clips, they fall astride the collecting bars.
  • EP-A-0 208 081 and the corresponding US-A-4,684,117 disclose a method and a device for opening eccentrically folded printed products with a fold trailing in the conveying direction and a leading edge region opposite the fold.
  • the printed products are held by individually controllable grippers of a conveying device and transported with the conveying direction running obliquely from above to below.
  • An opening device is provided below the conveying device, which has grippers arranged on a rotatingly driven pulling element.
  • a fixed support plate is provided to the side of the traction element and this is preceded by an endless support belt driven in rotation in order to support the printed products in the leading end region.
  • the edge section under which a gripping tongue of the gripper is opened is raised and the relevant transport clamp is briefly opened, so that the shorter product part below slides into the effective area of the gripper.
  • the shorter product part held thereby is again deflected in a direction transverse to the conveying direction when the gripper rotates around the deflection wheel and is moved away from the non-held product part above to open the printed product.
  • the abutting product parts of the printed products supported in their end area are lifted away from each other transversely to the conveying direction. This only has to be done in a small area, so that the product parts can be gripped easily by appropriate grippers of the opening device. Due to the grippers being driven at different speeds, the end edges of the product parts are now moved away from each other in the conveying direction. Since the product parts are held by the grippers, a forced separation of the product parts from one another is ensured, even if they should stick to one another. Since the grippers are moved in the conveying direction, there is a considerable amount of time available for opening. Furthermore, at least one of the product parts is bulged or brought into a position that is more stretched with respect to the other product part, so that the product parts are lifted from one another not only in the end region but up to the transport clamp.
  • the product part located at the top is raised, which can take place when the gripper assigned to the product part located at the bottom is opened by its moving clamping tongue engaging under the upper product part.
  • the opening device can thereby be particularly simple. If the product part with the edge section lying on top, it is easy to reach under the edge section, especially if the end edge of the printed product is brought into abutment against a stop on the gripper. The position of the end section is then precisely defined with respect to the clamping tongue.
  • the bottom product part is bulged in the end area against the top product part, so that the top product part lifts off from the bottom product part due to its inherent rigidity. Since this lifting off only has to take place along a small section of the end edge of the product part, it is also guaranteed for printed products with low inherent rigidity.
  • the bulging of the underlying product part of printed products which are held in their fold and are supported in the end region in such a way that they are bent can be done in a simple manner in that the edge section is bent on one side towards the bottom and with its end edge in the direction is pushed against the end edge of the overhead product part. It is possible that the top part of the product is now gripped directly by the corresponding gripper, without that being raised further by means of the clamping tongue of the gripper assigned to the bottom part of the product.
  • the device has a conveyor device 10 of a generally known type with transport brackets 14 arranged one behind the other at a fixed distance A on a chain conveyor 12 indicated by dash-dotted lines.

  • the active strand 42 'of the first pulling element 42 runs from the deflection wheel 46 to the deflection wheel 48 and thus overlaps the active strand 44' of the second pulling element 44, which extends from the deflection wheel 46 'to the deflection wheel 48' which is coaxial with the deflection wheel 48 '.
  • the distance C between the second grippers 40 is greater than the distance B between the first grippers 38.
  • the rotational speed v2 is correspondingly greater of the second pulling element 44 with respect to the rotational speed v1 of the first grippers 38.
  • These different speeds v1, v2 are generated in that the driven deflecting wheel 50 for the first pulling element 42 is correspondingly smaller in diameter than the deflecting wheel 50 'of the second pulling element 44.
  • the ratio of the speeds v1 to v2 behaves the same as the ratio of the distances B to C.
  • the grippers 38, 40 are of exactly the same design as described above and shown in FIGS. 6-13. Only the gripper jaw 68 of the first gripper 38 and gripper jaw 92 of the second gripper 40 are directed against the conveying direction F. Otherwise, the structure of the opening device 24 corresponds to the training forms already described above. Exactly the same reference numerals are used for functionally identical parts and they are only entered in FIGS. 27 and 28 to the extent necessary for the following explanation of the mode of operation.
  • a second gripper 40 which just before the end edge 32 'of the Product part 32 intersects the path of movement of the radially outer end of the second gripper 40, reaches the area of the active run 44 'and is pivoted backwards in the counterclockwise direction in the direction of conveyance F as seen by the dash-dotted pivot link 110 in order to open the edge section with its open gripper mouth 92 34 to embrace.
  • the clamping pin 90 When running off the opening link 104, the clamping pin 90 is raised and the edge section 34 is clamped between the latter and the gripper jaw 86.
  • the clamping tongue 64 When the first gripper 38 runs from the corresponding opening link 78, the clamping tongue 64 is moved into the closed position and clamps the product part 36 between it and the clamping jaw 66, which was pushed into the open gripper mouth 68 by the support band 146.
  • the product part 32 on top is now moved away from the product part 36 on the bottom in the direction of conveyance F and is thereby moved into a more extended position, as can be seen in particular in FIG. 28.
  • the product part 36 maintains its bend or is bent even more if the speed v1 of the first grippers 38 is lower than the conveying speed v of the conveyor device 10.
  • the second gripper 40 With the opening gate 104 'or 78', the second gripper 40 becomes first and later in time the first gripper 38 is opened in the region of the deflection wheels 48, 48 '.
  • the further processing of the printed products can be carried out in exactly the same way as is shown in FIGS. 1-3.
  • the opening device 24 can be used as they are 27 and 28, printed products 20 are also processed, which are fed to the opening device 24 with the leading end region 28 and the lower edge section 34.
  • the lifting off of the two product parts 32, 36 then takes place in an analogous manner, as shown in FIGS. 19-23 and described further above.
  • the clamping tongue 64 and the bending member 142 form separating means in order to lift the two product parts 32, 36 from each other transversely to the conveying direction F.
  • the two product parts 32, 36 can thereby each be securely gripped by the corresponding grippers 38, 40.
  • the deflection wheel 46 'for the second pulling element 44 with the second grippers 40 seen in the conveying direction F, is connected upstream of the deflection wheel 46 for the first pulling element 42 with the first grippers 38.
  • the active dreams 42 ′ and 44 ′ overlap.
  • the traction elements 42, 44 are driven in the same way as described above via deflection wheels 50, 50 '(compare FIGS. 25, 26), which are no longer shown in FIG. 29.
  • the speed v1 of the first grippers 38 and the distance B between these grippers 38 are correspondingly greater than the speed v2 of the second grippers 40 and the distance C between these grippers 40. Furthermore, the speed v2 is at least as great as, but preferably greater than the conveying speed v of the transport clamps 14 of the conveying device 10; the distances are a matter of course A and C matched accordingly.
  • the support plate 120 has a step 120 'falling in the conveying direction F in the deflection wheel 46. Up to this step 120 ', the support-active surface of the support plate 120 is above the clamping pins 90 of the opened second grippers 40, but of course below the gripper jaw 86. In the direction of conveyance F following the step 120', the support-active surface of the support plate 120 is aligned with the clamping jaw 66 the first gripper 38. In this embodiment too, the movement path of the gripper mouth 92 runs above the first grippers 38.
  • the structure of the grippers 38, 40 is exactly the same as described above and shown in FIGS. 6 to 13; however, the second grippers 40, like the first grippers 38, are fixed, i.e. are not pivotally arranged on the tension members 42, 44.
  • the opening scenes 78, 78 ', 104, 104' described above are not shown in FIG. 29; their position can be seen from the following functional description of the device according to FIG.
  • the printed products 20 which are held approximately vertically hanging by their clamps 22 from transport clips 14 are transported with their end region 28 resting on the support plate 120 at the conveying speed v.
  • the longer product part 32 with the edge section 34 is trailing and overhead with respect to the shorter product part 36.
  • the product part 36 located below is clamped and moved away from the other product part 32 in the conveying direction F.
  • the grippers 38, 40 are then opened one after the other, so that they release the product parts 32, 36 which are lifted from one another.
  • the structure of the opening device 24 shown in FIG. 30 is extremely similar to that of the opening device according to FIG. 29. In the following, only the differences are referred to, insofar as this is necessary for understanding.
  • the deflection wheels 46, 46 ', 48, 48', 50, 50 ' are arranged exactly the same and the traction members 42, 44 are guided in the same way as in FIG.
  • the speed v1 of the second grippers 40 is approximately the same large as, but preferably lower than the conveying speed v.
  • the speed v1 of the first gripper 38 is lower than the speed v2.
  • the distance A between the transport clamps 14 is the same as or greater than the distance C between the second grippers 40, and the distance B between the first grippers 38 is smaller than the distance C.
  • the support belt 146 is driven at a speed in the conveying direction F which is at least the same size, preferably greater than the conveying speed v, in order to feed the printed products 20 lying thereon with their end region 28 with the leading edge section 34 to the second grippers 40.
  • the support belt 146 which runs in a gap in the support plate 120 and projects with its active upper run over the support plate 120, is guided around a roller, not shown in FIG. 30, which is supported coaxially with the deflection wheel 46, so that it is in front of the deflection wheel 46 '' is supportive and supportive until the deflection wheel 46.
  • the traction elements 42, 44 are synchronized in such a way that in one area, beginning with the deflection wheel 46 until after the falling step 120 ′ in the support plate 120, the first gripper 38 in each case leads the corresponding second gripper 40 and then before reaching the deflection wheels 48, 48 'The second gripper 40 overtakes the first gripper 38.
  • the printed products 20 are conveyed by the transport clamps 14 hanging in the fold 20 approximately in the vertical direction.
  • the longer product part 32 is compared to the shorter one Product part 36 each leading, so that the end portion 28 is leading and the edge portion 34 is overhead due to the support band 146.
  • a second gripper 40 which is opened by means of the opening backdrop, not shown, swings in between two printed products 20 in each case.
  • the edge section 34 runs into the open gripper jaw 92, so that when the gripper 40 closes on the deflection wheel 46, the edge section 34, which is gripped by the clamping pin 90, is raised and clamped in the gripper jaw 92 .
  • the shorter product part 36 lying below falls further away from the upper product part 32 with its section adjoining the leading end edge 36' and reaches the mouth 68 of the first gripper 38, for example when this is overtaken by the corresponding second gripper 40 .
  • the clamping pin 90 and the step 120 ′ in the support plate 120 form the separating means in order to lift the adjacent product parts 32, 36 from one another transversely to the conveying direction.
  • the grippers can have a different design. It is also conceivable not to drive them around, but to move them back and forth.
  • the traction elements 42, 44 can also be driven individually. This enables simple synchronization and adaptation to different formats of the print products to be opened.
  • the printed products can be opened on the left, in the middle, or on the right. It is also conceivable to arrange two identical opening devices 24 next to one another, so that the printed products are opened simultaneously in two areas.
