Definitions

  • Embodiments of the invention relate to the processing of goods or groups of goods, in particular to the processing of sheets which are processed as single sheets or as groups of sheets within a paper handling system.
  • Paper handling equipment serve to generate letters for dispatch to a variety of recipients, with which, for example, telephone bills, bank statements or the like are sent.
  • cover letters consist of either a single sheet or a plurality of sheets, which are then processed within the plant as a group.
  • the sheets processed by the system are then inserted into an envelope by means of an inserter and sent to the recipient.
  • the sheets which form the plurality of cover letters are fed via one or more input channels, wherein collection of the sheets of a sheet group is required before being further processed together.
  • the sheets may for example be provided by a roll of paper on which the plurality of sheets is already printed, for example multi-purpose.
  • the roll is then fed via the input channel and first cut longitudinally and transversely to produce the cut sheets, which are then collected in a collecting station to the cut sheets or to the groups of sheets.
  • the speed at which sheets can be provided to a collection station may be different from the speed at which they are extended from the collection station to be provided for subsequent processing, such as a fold rate.
  • FIG. 1 schematically shows a paper handling installation comprising a plurality of landing stations, namely a cutter 100, a so-called merger 102, a collecting station 104 and a folding unit 106.
  • the cutter 100 receives at an entrance a paper web 108, which with the text of the later to be produced single sheets 1 10 and 1 12 is printed multi-useful.
  • FIG. 1 shows in the upper section a schematic representation of the processed sheets, and in the lower part a schematic side elevational view of the sheets.
  • the cutter 100 causes a longitudinal section of the paper web 1 08 and a cross section thereof to singulate the single sheets 1 10 and 1 12, so that these, as shown in Fig. 1, individually present after cutting.
  • the single sheets 1 10 and 1 12 parallel to the Merger 102, the merge path passed, which moves both leaves 1 10 and 1 12 so that they are arranged one above the other, as shown in Fig. 1.
  • the sheets thus arranged are transferred from the merger 102 to the collection station 104.
  • the collection station 104 follows the folder 1 06.
  • a buffer 1 14 (shown by a buffer line 1 14) arranged in which a plurality of cut sheets or groups of sheets 1 16a-1 161 are arranged, for example in a shingled arrangement, as shown in Fig. 1.
  • the collecting station 104 is designed to deposit the received sheets 1 10, 11 2 at a first buffer station along the buffer section 14 of the buffer. At the end of the buffer section 14, the group of sheets located at the last buffer position or the single sheet 1 161 located there is removed, at a speed corresponding to a processing speed of the following component, here the folding unit.

  • the further processing can either be that, for example, the short sides of the folded sheet group 1 1 8 'are sealed, so that here already the mail piece to be sent is completed.
  • at least one of the single sheets 1 10, 1 12 is printed such that after the folding process, an addressee is externally visible.
  • the folded sheet group 1 1 8 ' can be fed to an inserter, which then inserts the sheet group 1 18'.
  • the provision of the buffer path 14 allows decoupling of the processing speeds of the components, which are arranged in front of the collecting station 104, from the processing speed of the components which are arranged after the collecting station 104.
  • Conventional buffer sections 14 operate in such a manner that a single sheet or a group of sheets is deposited at the first buffer station 16a and regardless of the filling state of the buffer section 14, each individual buffer station 16a-161 passes through according to the speed of a designated buffer transport. If the group has arrived at the exit of the buffer section 1 1 4, it will be deducted.
  • a buffer is not limited to the configuration of a package handling application shown in FIG. Basically, such a buffer will be used everywhere. set where a decoupling of the speeds is required, for example, where a precursor component provides a good or a good group at a speed that can be higher than a speed with which a Nachêtrkomponente can take over the good or the product group.

  • the vacuum chambers of the upper transport 41 2 and the lower transport 414 marked with an "x" are inactive, ie despite a movement of the corresponding belt 412a or 414a, there is no conveyance of a good or a product group at these positions.
  • the buffer section 400 comprises the lower and upper drives or transports 412 and 414 which are just described and which can each be controlled separately from one another. More specifically, the respective drives each comprise separately controllable vacuum chambers, the number of vacuum chambers is not limited to that shown in Fig. 1 0, but also more or fewer vacuum chambers may be provided, as long as more than one vacuum chamber in each transport , An activation of the vacuum chambers takes place in accordance with exemplary embodiments via a multi-channel valve.
  • the functionality of the buffer section 400 described with reference to FIG. 10 is such that the upper transport 406 is responsible for taking over a good or a product group from the inlet 402 and for transporting the goods or the product group along the buffer route.

  • the space required vacuum chambers 41 4d of the lower transport here the right five vacuum chambers activated.
  • a leaking Good at 41 6 is shown, which is moved by the lower transport 414 in the direction of the spout 404.
  • the lower vacuum transport 414 runs at a higher speed than the buffer transport, which speed is preferably equal to the discharge transport.
  • the upper and lower vacuum chambers 412d and 414d are synchronously controlled according to the position and length of the leaking material.
  • the boundary curve of the active and inactive vacuum chambers 412d is displayed, which runs along with the position of the issued good.
  • the buffer fills faster in smaller groups than in larger groups, so that when picking up small groups, the last occupied buffer position moves towards the spout 404, whereas for larger groups the last occupied position is in the direction of the spout Inlet 402 migrates, as indicated by the arrow 41 8.
  • the vacuum caramers 412d are activated / deactivated accordingly.

Abstract

L'invention concerne un dispositif d'amortissement de plusieurs produits ou groupes de produits comprenant un trajet d'amortissement (204) conçu pour recevoir une pluralité de produits ou de groupes de produits. Un transport d'amortissement (209) est conçu pour déplacer un produit ou un groupe de produits à une vitesse de transport d'amortissement. Une sortie (212) est conçue pour sortir un produit ou un groupe de produits du dispositif à une vitesse de sortie supérieure à la vitesse de transport d'amortissement. La sortie (212) est en outre conçue pour assurer le transport d'un produit ou d'un groupe de produits avant que le produit ou le groupe de produits ait atteint une extrémité du trajet d'amortissement (204; 400).
