Definitions

  • the present invention relates to a method and a device for further processing of stacked, preferably folded printed products, according to the preamble of claim 1 and claim 6.
  • a device for further processing of stacked printed products of this type is known.
  • the lowest printed product in the stack is detected in the area of a corner by means of a suction head and drawn between two separating rollers which are moved along the base of the stack and form part of a stack support. Due to the separating roller moving between the lowermost printed product and the overlying printed product, the lowermost printed product is detached from the stack and falls onto a conveyor which is arranged below the stack.
  • the stack is aligned so that it has two side edges that are perpendicular to the conveying direction of the conveyor.
  • the printed products thus detached are led away by the conveyor in a scale formation, in which the printed products lie on top of one another in the manner of roof tiles and with their leading edges run at right angles to the conveying direction of the conveyor.
  • this device has shown that the stack has to be pivoted by a small angle of a few degrees in relation to the conveying direction of the conveyor in order to form the desired scale formation on the conveyor, in which, as already mentioned, the printed products run with the leading edge at right angles to the conveying direction of the conveyor.
  • This slight inclination of the stack is necessary because the separation of the printed matter begins at a corner thereof and the detachment of the printed matter continues in a direction which is transverse to the conveying direction of the conveyor, which means that the individual areas of the detached printed matter come to rest one after the other on the conveyor.
  • Such devices with a stack that is slightly inclined relative to the conveying direction of the conveyor are sold by Ferag AG under the name "Schnellanleger RA" (High-Speed Hopper RA).
  • the devices described above have the advantage of a high degradation performance, but have the disadvantage that access to the individual printed products in the shed formation is associated with a certain effort for the purpose of individual processing of the printed products.
  • CH-A-637 087 a device of a similar type is known (CH-A-637 087), but which is of somewhat different construction and in which the stack is not inclined neither to the direction of movement of the separating rollers forming the stack support nor to the conveying direction of the conveyor.
  • a device for pulling off the bottom sheet from a stack in which the bottom sheet is gripped by a suction head and pulled down into the effective area by two pull-off rollers.
  • the stack of sheets is inclined with respect to the direction of withdrawal of the rolls, so that the sheets are transported away by the take-off rolls with the corner previously gripped by the suction head.
  • the sheets are pulled off and carried away one by one and one after the other, as a result of which the degradation performance is lower compared to the known devices mentioned above.
  • the present invention is based on the object of creating a method and a device of the type mentioned at the outset, which, at high output, permits easier processing and processing of individual printed products in the removed scale structure than is possible with the known devices explained at the outset is.
  • a conveyor is connected downstream of the conveyor belt and guides the products removed from the stack in a scale formation.
  • This conveyor is now arranged in such a way that its conveying direction also includes an angle of 45 ° with the conveying direction of the conveyor belt, as a result of which the inclined position of the stack relative to the conveyor belt is canceled again by 45 ° and the side edges of the products carried away by the conveyor are at right angles, or run parallel to the conveying direction of the conveyor.
  • a stacking table 8 with stops 9, 10, 11, of which the stops 9 and 10 are designed as corner stops.
  • These stops 9, 10, 11 define a cuboid stacking space 12 (FIG. 1), which is inclined with a corner 12a pointing towards the direction of movement A of the separating rollers 2.
  • This inclination of the stacking space 12 is shown in Fig. 1 by the angle ⁇ .
  • This angle ⁇ is approximately 20 °.
  • the stacking space 12 is used to hold a stack 13 of folded printed products 14, e.g. Newspapers, magazines and parts thereof (Fig. 2).
  • the fold edge of these printed products 14 is designated by 14a, while their side edges are designated by 14b and 14c and their open side by 14d.
  • the corner stop 9 is fixed, while the stops 10 and 11 can be adjusted by means of an adjusting mechanism 15 and 16, respectively, in order to be able to adapt the size of the stacking space 12 to the format of the printed product 14 to be processed.
  • the separating rollers 2 move during their rotation in the direction of arrow A along the base surface 13a of the stack 13 (FIG. 2) and roll on the lowest printed product 14 in the stack 13.
  • the direction of rotation of the separating rollers 2 is indicated by the arrow B in FIG. 2. It is necessary that the peripheral speed of the separating rollers 2 corresponds to their feed speed.
  • a friction bar is provided adjacent to a chain, which is shown only schematically in FIG. 1 and is designated by 17.
  • the separating rollers 2 roll with their conical end on this friction bar 17, which is adjustable in a manner not shown at right angles to the direction of movement A of the separating rollers 2.
  • a suction head 18 which is attached to one end of an angle lever 19 (FIG. 2).
  • This angle lever 19 is guided at the other end by means of a roller 20 in a guide rail 21.
  • the angle lever 19 is further connected to a planetary gear 23 by means of a joint 22.
  • the structure of the drive for the suction head 18 and the movement path of the latter generated thereby are described in more detail in the previously mentioned CH-PS 598 106 (or the corresponding US-PS 4 127 262).
  • the suction head 18 can also be periodically connected to a vacuum source, not shown.
  • the suction head 18 moves periodically between two adjacent separating rollers 2, detects a corner 27 of the lowermost printed product 14 'and pulls this corner 27 between successive separating rollers 2, as shown in Fig. 2. Due to the separating roller 2 entering the opening between the lowermost printed product 14 'and the overlying printed product 14', the lowermost printed product 14 'is launched 13 replaced.
  • the suction head 18 is disconnected from the vacuum source at the appropriate time and moves up again through the space between the two following separating rollers 2 to detect the next printed product 14 Druck, such as that in the aforementioned CH-PS 598 106 and the corresponding one U.S. Patent 4,127,262 is described in more detail.
  • the less pronounced inclination of the stack 13 ( ⁇ approx.
  • a conveyor 24 is arranged below the stacking support 1 and under the stacking space 12, the conveying direction C of which forms an angle ⁇ with the direction of movement A of the separating rollers 2 (FIG. 1).
  • the stacking space 12 is now inclined with one of its corners 12b in the conveying direction C of the conveyor 24 by an angle ⁇ (FIG. 1) such that the printed products 14 detached from the stack 13 with all side edges 14a, 14b, 14c and 14d transversely to the conveying direction C. of the conveyor 24 running on this conveyor 24 or in the manner of a roof tile on the previously detached printed product 14, as can be seen particularly clearly from the floor plan figure 1.
  • This inclination of the stacking space 12 with respect to the conveying direction C of the conveyor 24 is now selected such that the angle ⁇ mentioned is greater than approximately 15 °.
  • the stacking space 12 is preferably inclined such that this angle ⁇ is between approximately 30 ° and 60 ° and in particular between approximately 30 ° and 45 °.
  • the printed products 14 are placed overlapping on the conveyor 24 and guided away from it in a scale formation S, in which one corner 25 of the printed products 14 runs ahead.
  • a scale formation S in which one corner 25 of the printed products 14 runs ahead.
  • two corners 26 and 27, which are located to the side of the scale formation S, are completely free in this scale formation S which is carried away.
  • the folded edge 14a and one side edge 14b are complete and the other side edge 14c and the open side 14d are only partially accessible.
  • an L-shaped area 28 is not covered by the next printed product 14 lying above it. This area 28 is thus also accessible.
  • Placing the printed products 14 detached from the stack 13 in the scale formation S shown in FIG. 1 has the further advantage that the height H of the scale formation in the region of the corner 12a of the stack space 12 is relatively low (see FIG. 4). This makes it possible to arrange the conveyor 24 comparatively close to the underside of the stack 13a, so that the drop height of the detached printed products 14 is as small as possible.
  • FIG. 3 shows a variant of the device according to the invention in a representation corresponding to FIG. 1, in which the detachment of the printed products from the stack 13 and the depositing of the printed products 14 on the conveyor 24 in a scale formation S takes place in the same way as that with the aid of FIG 1 has been explained. Because of this identity between the embodiments according to 1 and 3 are no longer all reference numerals entered in the latter.
  • the embodiment according to FIG. 3 differs from that according to FIG. 1 in that the conveyor 24 is followed by another conveyor 30 and / or 31.
  • the conveyors 30, 31 have a conveying direction E or F, which forms an angle ⁇ or ⁇ 'with the conveying direction C of the first conveyor 24.
  • the conveying direction E or F of the downstream conveyors 30, 31 is selected with respect to the conveying direction C of the first conveyer 24 so that in the shingled formation S 'carried away by these downstream conveyors 30, 31, the printed products 14 assume a position in which the leading edges 14a and 14b is perpendicular to the conveying direction E and F of the conveyors 30 and 31, respectively.
  • a "normal" scale formation S ' can be formed in a simple manner from the scale formation S conveyed by the conveyor 24, as is often required for further processing. It should also be pointed out that in the scale formation S 'carried away by the conveyor 30, the leading edge of the printed products 14 is formed by the folded edge 14a, while in the scale formation S' which is led away by the other conveyor 31, the leading edge is formed by the Side edge 14b is formed.
  • the removal conveyor 24 is arranged such that the printed products 14 are led away with the corner 25 in front.
  • the conveyor 24 it is entirely possible to arrange the conveyor 24 with the conveying direction opposite to the conveying direction C, so that the printed products are led away with their corner opposite to the corner 25 and the open side 14d ahead.
