Definitions

  • the invention relates to a method for receiving an auxiliary stack when replacing a stack of sheets in a sheet delivery of a sheet-processing machine according to the preamble of claim 1 and an apparatus for performing the method according to claim 11.
  • auxiliary stackers are often provided for carrying out a non-stop stack change, which are retractable during the conveyance of sheets from a sheet-processing machine in a stacking area of the sheet delivery.
  • facilities are used for example in the form of so-called blinds.
  • a roller blind consists of a series of support elements, which can be moved by means of a drive chain in a gap of the conveyed sheet flow in the region of the sheet delivery.
  • the support members may be wrapped by a blind cloth, thus forming a flat storage surface and take during the replacement of a sheet stack from the sheet delivery during his bow further promoted. In this case, it must continue to be ensured that the sheets resting on the auxiliary stack are stored with the exact edges.
  • the exact stacking should also be maintained when the auxiliary stacking devices are removed from the stacking space again and the stacking process continues normally. It is also important that the roller blind can be moved into the stack area without interference. It must be ensured that no sheets are hit during insertion and thus moved on the stack or even damaged.
  • a device of the type mentioned is out EP 0 987 105 A2 known.
  • a plurality of arch supports which are mountable at different locations along a support of the apparatus with the aim of supporting them in contact with the undercut edge of a sheet at locations of pressure-free corridors.
  • the arch supports are rod-shaped and are Moving the same in the longitudinal direction together spent from a standby position in a catch position.
  • One object of the arch supports is to form a gap between a sheet processed in particular by means of a rotary printing machine stacked in the sheet delivery and a bow following on the uppermost sheet, in which then for stack change in the continuous printing an auxiliary pile pad, for example, said roller inserted becomes.
  • roller blind must be very accurately retracted into a gap in the sheet so that it can fall under falling sheets fully and thus can safely accommodate. Furthermore, it is difficult to avoid that depending on the type of printing sheet are hit at its trailing edge, which can lead to disturbances to the damage in the sheet delivery. Finally, the arrangement of the receiving finger in the area below the upper edge of the blinds structurally unfavorable, since appropriate free areas are provided in the blind.
  • auxiliary pile supports such as e.g. an auxiliary stacking device with blind
  • auxiliary pile supports can come in a sheet delivery to a production stoppage ranging from crumpled through the blind sheet up to a machine damage.
  • the cause lies essentially in the collision of the respective auxiliary pile carrier (roller blind, sword, rake, etc.) with an edge of a sheet falling on the sheet pile.
  • auxiliary pile carrier roll blind, sword, rake, etc.
  • the aim of the invention is therefore to avoid a shift already resting bow through the roller blind safely and to make the process of taking over the auxiliary stack trouble-free.
  • the object of the invention is to develop a method according to the preamble of claim 1 and an associated device in the simplest possible way so that a safe at all substrates or machine speeds entry of the auxiliary stack support is made possible without shifting resting bow.
  • a method is proposed in which a support or a separating device is arranged in the sheet delivery that the trailing edge and the leading edge of a collision-prone sheet are held so high that the or the auxiliary pile carrier can safely enter below.
  • the support or separation device is arranged so that, after lowering the main stack, with the front and rear edges of the sheet held down lower in the stack center on the surface of the sheet pile and can support it, so that the sheet is held securely until the Auxiliary pile carrier completely is retracted into the stacking area.
  • the auxiliary pile carrier takes over the bow from the surface of the sheet pile.
  • the method allows that separating operations are easily carried out when a first sheet rests only on the front support means, while a second subsequent sheet rests on both the front and on the rear support means.
  • a device is further proposed, in which a support or a separating device is arranged in the sheet delivery that the trailing edge of a collision-prone sheet is held so high that the or the auxiliary pile carrier can drive safely underneath. Furthermore, a further support or separating device is provided which holds up the leading edge of the same sheet, so that the sheet is held at the entrance of the auxiliary pile support on two support or separating devices until the auxiliary pile carrier is fully retracted into the stacking area.
  • This device consists of a plurality of support elements, which are arranged in the sheet delivery above the auxiliary pile carrier and the front of the sheet stack of the sheet stack and stand outside of the sheet format.
  • the support elements can be tapered and rounded at their end.
  • the support elements may be connected to one or more mechanical cross-linking elements whose length is variable, e.g. an elastic cord, a spring-loaded wire rope, a telescopic rod, etc.
  • the support elements In response to a control signal, the support elements enter the stacking space and the beginning and the end of a sheet come to lie on it.
  • auxiliary stack carrier retracts only when it is ensured that the sheets still falling beneath the support elements have also arrived in the area below the auxiliary stack carrier.
  • a corresponding timing provided or the falling sheets are detected by sensors below the support elements.
  • FIG. 1 shows a schematic overview of a sheet delivery 1 for a so-called non-stop stack change.

  • an auxiliary stack support 5 - for example in the form of a roller blind - arranged, which is retractable during a stack change in the stacking area of the sheet delivery 1 and by means of which an auxiliary stack 6 can be formed there at times.
  • the auxiliary stack carrier 5 consists of support elements, such as rods or tubes, which are guided on drive chains on guides in the stacking area of the sheet delivery 1 retractable.
  • the auxiliary pile support 5 can be provided with a blind cloth covering the support elements, so that a substantially smooth deposition surface is formed on the auxiliary pile support 5. It is also possible to use narrow ribbons or strings to surround the roller blind rods in order to bridge the spaces between the roller blind rods. This sheet edges, in particular the first sheet to be deposited can not get into these spaces.
  • auxiliary stack carrier 5 On the auxiliary stack carrier 5 sheets are deposited to an auxiliary stack 6, wherein the auxiliary stacking device 2 at the Hilfsstapelhubwerk 4 during the formation of the auxiliary stack 6 to maintain a proper distance of the surface of the auxiliary stack 6 of the sheet releasing conveyor system 10 is raised and lowered.
  • the main stack 7 of the sheet delivery 1 is positioned below the auxiliary stack 6 on a pile support plate 8 at a Stapelhubtechnik 9 and is removed in a stack change from the sheet delivery 1, while the auxiliary stack 6 is formed on the auxiliary stacking device 2.
  • auxiliary pile carrier 5 For inserting the auxiliary pile carrier 5 in the stacking area during the production process, ie while the conveyor system 10 continuously supplies sheets, it is first necessary to define a gap in the sheet flow, in which the auxiliary pile carrier 5 can be retracted. Furthermore, it should be ensured that the sheet or sheets resting on the auxiliary pile carrier 5 can not be displaced beyond the boundary by the front stacking stops 11 during its entry into the stacking area.
  • this support elements 15, 16 are arranged in the sheet delivery 1, that a trailing edge of a collision-prone sheet B is held up while the auxiliary pile support 5 is retracted thereunder. Furthermore, a leading edge of the sheet B is supported in the region of the front stack stops 11.
  • the support elements 15, 16 consist of one or more transverse to the sheet transport direction R in the region of the front and rear upper edge of the sheet stack 7 arranged separating elements, the underside of which is arranged above the upper edge of the auxiliary stack carrier 5.
  • the position of the support elements 15, 16 must be in the rest state outside the predetermined by the sheet stack 7 sheet format.
  • the support elements 15, 16 may be bevelled at their leading edge facing the stack area.

  • the support elements 15, 16 may each be provided with an edge stop, which serves for fixing at least the lowermost resting sheet at the front and rear edge in the retracted position.
  • pneumatic cylinders can be provided, by means of which the support elements 15, 16 are movable directly or indirectly parallel to the sheet transport direction R.
  • the drive can alternatively also be mechanical, electrical or hydraulic.
  • a control signal is generated by the machine control or manually controlled by the operator on the way drives the support elements 15, 16 retract into the stacking space on the format edge of the sheet pile 7.
  • the front end of a sheet B rests on the support member 16 and the rear end of a sheet B comes to lie on the support member 15.
  • the sheet B can rest on its edges on separate edge stops on the support elements 15, 16.
  • the support elements 15, 16 are usually arranged horizontally or parallel to the sheet transport direction R. Depending on the type of substrate is one in sheet travel direction R sloping arrangement advantageous. For this purpose, an adjustability can be provided such that the angle of inclination of the support elements 15, 16 can be changed.
  • the auxiliary stack carrier 5 only enters when it is ensured that the sheets B still falling underneath the separating device 15 have also arrived in the area below the auxiliary stack carrier 5. For this purpose, e.g. Waiting a corresponding time or the falling bow are detected as described below the height of the support element 15 sensor.
