Definitions

  • the present invention relates to a method and a device for opening folded, bound or stapled multi-sheet products, in particular printed products, according to the preamble of claims 1 and 5 respectively.
  • the invention further relates to a device for processing, in particular inserting, printed products.
  • a method and an apparatus of this type are known from CH-A-644 815 and the corresponding US-A-4,420,146.
  • the folded product to be opened is placed on a flat support element with an open side leading towards a stationary opening element.
  • This opening element has a flat tongue-like piercing element which is fastened to a shaft which runs approximately parallel to the support element and at right angles to the conveying direction of the product.
  • the piercing member can be rotated with this shaft and points in its starting position with its pointed piercing end against the incoming product. With this piercing, the inserting element sticks between sheets of the product.
  • the shaft and the piercing element are then rotated about their longitudinal axis, while the feed movement of the product continues.
  • This method and the corresponding device only allow moving products to be opened. Furthermore, the supplied product can be fanned out in the area of the open side, so that the product is opened between wrong sheets. Moreover, in the known device, adjustment work must be carried out precisely for processing products of different thicknesses.
  • FIG. 1 shows part of a device for processing folded printed products 10, which are transported step by step in the conveying direction F by means of a transport device 12.
  • the printed products 10 lie with one of their flat sides on a flat support element 14 and are fed to an opening device 16.
  • the printed product 10 comes into contact with the flat side facing the support element 14 on an opening element 18 designed in the manner of a segment of a disc and is pressed against it by means of a self-resilient pressing element 20 with little force, so that the printed product 10 is held together with sheets lying against one another.
  • the pressing element 20 thus forms a counter element 22 which interacts with the opening element 18.
  • the piercing end 26 of the piercing member 24 is in relation to an axis of rotation 18 ' right-angled support surface 34 of the opening element 18, against which the printed product 10 rests in the starting position 23 of the opening element 18, offset in the direction against the pressing element 10 acting as counter element 22 by a predetermined distance A (see FIG. 6).
  • This distance A thus precisely defines the point where the printing product 10 is pierced, since this lies against the bearing surface 34 in a defined manner under the action of the pressing element 20.
  • the printed product 10 is thus opened further from the open side 30 in the area of the corner to the likewise open, leading side 30 'by turning the opening element 18 further after the piercing into the open position 23' in that the on the piercing member 24 lying sheets from the remaining sheets, ie those between the support member 14 and the piercing member 24, are lifted in regions.
  • the printed product 10, which is now partially open in the area of the leading side 30 ', is moved in the conveying direction F against a stationary, wedge-shaped separating element 36 which moves in between the sheets which are lifted off one another and is moved past it.
  • a stationary, wedge-shaped separating element 36 which moves in between the sheets which are lifted off one another and is moved past it.
  • the sheets mentioned are lifted further apart and the printed product 10, which is now fully open, is kept open during further transport by a fixed, rail-like hold-open member 38.
  • an insert 42 is now inserted into the opened printed product 10.
  • the transport device 12 is of a generally known type and has controllable clamps 44 which are driven to and fro in the conveying direction F (see also CH-A-575 303 and US-A-4,058,202).
  • the clamps 44 are transferred to the closed position, where they clamp the respective printed product 10 at the collar 28 and take it with them.
  • the clamps 44 are opened, so that the printed products 10 stand still with respect to the support element 14.
  • the opening device 16, the separating member 36 and the open holding member 38 are outside the effective range of the clips 44.
  • the processing device according to FIG. 2 also has a flat support element 14, against which the printed products 10 are transported in the conveying direction F by means of the transport device 12.
  • the printed products 10 are first fed to the processing device in the feed direction Z with the collar 28 ahead. They come to rest with a flat side on the support element 14 and with their collar 28 in the effective area of the clamps 44, which of course are opened during insertion and then transferred to the closed position for holding the printed products 10.
  • the opening device 16 is arranged at the feed point 40 for the printed product 10, and in order to enable the feed, the opening element 18 is about a pivot axis 46, which runs parallel to the support surface 14 ′ and approximately at right angles to the conveying direction F, in the direction opposite to the arrow 46 'pivotable into a rest position 47 distant from the support element 14.
  • the opening element becomes 18 is pivoted in the direction of arrow 46 'into a pressure position 47', where it comes to rest on the printed product 10 on the flat side facing away from the support element 14.
  • the support element 14 is here the counter element 22, of which the printed product 10 is now held together in the piercing area 32 together with the opening element 18.
  • the opening element 18 rests with its bearing surface 34 on the printed product 10 and since in this case the piercing end 26 of the piercing member 24 in the direction against the support element 14 by a distance A from the bearing surface 34 is spaced, now after the reversal of the direction of rotation, the piercing member 24 pierces with the piercing end 26 between sheets of the printed product 10 in the piercing area 32 on the open side 30.
  • the opening element 18 By turning the opening element 18 further in the piercing direction E, these sheets are now lifted further apart by lifting the sheets resting on the piercing member 24 on the side facing away from the supporting element 14. It should be noted that when the open position 23 'is reached again, the opening element 18 with its bearing surface 34 has run off the printed product 10, but remains with its piercing member 24 in the opened printed product 10.
  • two printed products 10 can be fed with one another and one on top of the other in the direction Z, the respective upper printed product 10 being opened by the opening device 16.
  • the printed product 10 which has already been opened in each case is also opened in the region of a second one, shown in FIG. 3, by means of the hold-open member 38 Opening device 16 kept open.
  • this opening device 16 which corresponds to the embodiment shown in FIG. 1, the printing product 10 lying at the bottom, ie the printing product 10 resting on the support element 14, is now opened. This in turn comes to rest on the bearing surface 34 of the opening element 18 and is pressed against it by means of the self-resilient pressing element 20 acting as counter element 22.
  • the opening device 16 shown in greatly simplified form in FIG. 2 will now be described in more detail with reference to FIGS. 4 to 7.
  • the opening element 18 of the opening device 16 is designed in the manner of a disk segment and has a passage 52 which runs transversely to the bearing surface 34 on. This is open at the edge 54 of the opening element 18 that is radially outer with respect to the axis of rotation 18 ′.
  • the portion 56 of the opening element 18 leading the passage 52, the flat support surface 34 is formed and the piercing member 24 is integrally formed on the portion 56 'trailing the passage 52.
  • the pointed insertion end 26 of the essentially flat insertion member 24 projects by a distance A from the support surface 34.
  • the flat side of the printed product 10 facing the opening element 18 is indicated by dash-dotted lines.
  • an area 58 adjoining the piercing end is flat and parallel to the support surface 34. With this area, the opening element 18 located in the open position 23 'comes to rest on the printed product 10 when it is brought into the pressure position 47'.
  • the piercing member 24 is wedge-shaped and, after piercing with the side facing away from the region 58, lifts the undercut sheets of the printed product 10 planarly from the other sheets, the lifted sheets engaging in the passage 52, as is shown in FIG. 10 to 15 is still to be described.
  • the trailing part 56 At the end region distant from the piercing end 26, the trailing part 56 'has, on the upper side facing away from the support member 22, a ramp-like thickening 60 protruding from the rest of the opening element 18, so that after the piercing, when the opening element 18 is rotated further in the piercing direction E, the leaves the printed products 10 stand out from each other.
  • the passage 52 which is elongated approximately in the radial direction, has its greatest width, seen in the tangential direction, in its inner end region and is narrowest at the outer edge 54.
  • the piercing end 26 seen in the circumferential direction, lies at the trailing edge region 62 of the leading part 56 and is offset relative to the latter only in the direction of the axis of rotation 18 '.
  • the passage 52 preferably has a drop-like or airfoil-like cross section. In the open position 23 'of the opening element 18, the longitudinal direction of the passage 52 runs transversely to the conveying direction F, whereas in the initial position 23 that of the conveying direction F is opposite.
  • the disk-segment-like opening element 18 is mounted on a support element 64 made of a rigid or, if appropriate, an elastically flexible material, freely rotatable about the axis 18 ′.
  • a two-armed, angled actuating lever 66 is also pivotably arranged on this supporting element 64, the end of the actuating lever facing the opening element 18 via a tab 68 is articulated with that.
  • the point of engagement of the tab 68 on the opening element 18 is eccentric with respect to the axis of rotation 18 ′ running at right angles to the bearing surface 34, so that when the actuating lever 66 is pivoted, the opening element 18 is rotated.
  • a follower roller 70 is also freely rotatably mounted on the end facing away from the opening element 18 and cooperates with a control surface 72 of a rotary link 72 'to counteract the action of a tension spring 74 and thus the opening element 18 from the open position 23' against the action of a tension spring 74. to pivot into the starting position 23. From the starting position 23 back to the open position 23 ', the pivoting takes place by the force of the tension spring 74, the pivoting position being able to be provided by the control surface 72.
  • the tension spring 74 acts between the arm of the actuating lever 66 facing the opening element 18 and the support element 64.
  • the support element 64 in turn is mounted on a fastening member 76 so as to be pivotable about the pivot axis 46 which runs approximately parallel to the support surface 14 'and at right angles to the conveying direction F (see in particular FIG. 7).
  • a control lever 80 is formed on the support element 64, which extends approximately in the radial direction with respect to the pivot axis 46 and carries a freely rotatable control roller 82 at its free end.
  • a second tension spring 84 On the control lever 80, one end of a second tension spring 84 is fastened, the other end of which engages the fastening element 66 and pulls the support element 64 together with the opening element 18 in the direction toward the rest position 47 remote from the support element 14, where the support element 64 counteracts the force of the second tension spring 84 is supported in a known manner.
  • the control roller 82 cooperates with the control surface 86 of a swivel link 86 ', which counteracts the force of the second tension spring 84 pivots the support element 64 and thus the opening element 18 into the pressure position 47 '.
  • the separating member 36 which thickens in a wedge-like manner in the conveying direction F, is also fastened to the support element 64. Its front edge 88 facing the opening element 18 is flush with the flat opening element 18 and, in the starting position of the opening element 18, is adjacent to its edge facing the front edge 88, so that the sheets of the printed product 10 transported in the conveying direction F are inevitably moved past both sides of the separating member 36.
  • the fastening member 76 is fastened in the end region 90 of the support element 14 facing away from the transport device 12.
  • the support element 14 has a profile-like wall element 92 to which a support plate 94 forming the support surface 14 'is fastened.
  • the wall element 92 has an undercut, longitudinally extending fastening groove 96, to which the fastening member 76 is fastened in a known manner in a displaceable and fixable manner.
  • a plurality of support elements 14 are arranged in a known manner around a common rotation axis, not shown, these support elements 14 delimiting receiving parts 98 which extend in the longitudinal direction of the rotation axis and are radially open to the outside.

Compared to the contact surface 34, the piercing end 26 of the piercing member 24 is offset upwards by a predetermined distance A in the direction of the axis of rotation 18 '. Furthermore, the leading part 56 has a ramp-like bevel 102 along a section of its radially outer edge 54 with respect to the bearing surface 34, which is directed towards the conveying direction F when the opening element 18 is pivoted in the starting position 23. This is to ensure that the printed products 10 lying on the support element 14 slide with certainty onto the opening element 18. It should be noted that in this embodiment the support plate 94 of the wall element 92 is seen in the conveying direction F, is designed to rise towards the opening device 16 and ends at a small distance in front of the outer edge 54 of the opening element 18.
  • the printed product 10 to be opened is advanced in the conveying direction F into the position denoted by 10 'in FIG. 9. Then, the opening element 18 is pivoted in the piercing direction E, whereby the piercing member 24 pierces the piercing end 26 into the open side 30 and, as the trailing part 56 ′ continues to rotate, lifts the sheets of the printed product 10 lying thereon from the sheets facing the supporting element 14.
  • the open position 23 'of the opening element 18 when the printed product 10 is open corresponds to that position which is shown in solid lines in FIG. 6.
