  • the invention also relates to a set of elements comprising an ejector plate and a set of ejectors for preparing a superior form of ejection.
  • Presses for shaping sheets of compact cardboard or corrugated cardboard intended for the production of packaging include generally several stations, placed one after the other in the press, which the sheets pass through successively. From an introducer or feeder, the leaves pass, at a tactical pace, a cutting where each sheet is cut into one or more poses, which remain connected to each other by fasteners and carry with them the waste sheet located around and between them, an ejection station where the waste resulting from the cutting are removed, then a station of separation of the poses where the ties are broken, as a result of which the poses are stacked.
  • the cut sheet is placed on a perforated board, the central ejection board, comprising a plurality pre-cut days. These openings are located next to the waste of the leaf and have a shape broadly corresponding to these, while with a slightly larger outline.
  • the central ejection board uses at least one mobile upper ejection tool which, when descending perpendicular to the cardboard sheet, pushes the waste through the openings of the central ejection board.
  • a superior ejection tool As a superior ejection tool, a upper form of ejection consisting of a wooden board, on which are fixed, by screwing, nailing or gluing them, at the locations corresponding to the waste to be ejected, ejectors of various shapes and adapted to the shape of the waste, such as nails, pins, blades or blocks of wood.
  • the preparation of such a form of ejection requires long and meticulousness of a formist; such a form of ejection can only be used for a single cutting diagram.
  • a universal ejection tool comprising a ejector plate, consisting of a pair of identical perforated sheets a large number of holes over their entire surface and mounted on a frame tubular.
  • the ejectors are chosen from rectangular blocks fitted with magnetic fixing studs and ejection needles consisting of a rod folded twice at right angles to form a U with two unequal branches length, which are introduced both into two pairs of holes of the two sheets perforated and remain there thanks to the relative elasticity of the two branches.
  • Patent CH-682651 describes a mobile upper station tool separation of poses, consisting of punches and a plate provided with openings intended for the passage of air, which carries them.
  • the underside of the plate is covered with a layer of hanging fibers of the "velcro" type or similar.
  • the upper side of each separation punch is covered with a second layer of hooked conjugated fibers, "velcro" or the like, intended to come into engagement with the layer of fibers covering the plate for secure the punch to the plate.
  • the punches are arranged with a way that corresponds to the locations of the fasteners between the poses of a leaf. This tool is modified for each job and allows not to store a large number of pose separation tools, each corresponding to a given work.
  • Automated shaping presses are capable of processing several thousand sheets per hour. Small series of poses for packaging itself contains only a few thousand copies. he it is therefore economically imperative to be able to move from work to the other, i.e. to prepare the shaping tools and the introduction of tools into the machine, formatting and maintenance, without the machine has been stopped for more than a few minutes.
  • An object of the invention is to propose means of achieving quickly preparing the shaping tools, in particular the shaping of the ejection station, in masked time, that is to say while the machine does another job, drawing on a limited stock of parts standardized.
  • Another object of the invention is to prepare these tools in such a way so that setting up in the station does not require adjustments tedious. Finally, the preparation must be as precise as the work of a formist.
  • This process can be carried out in accordance with the invention using an adjustment table comprising a frame carrying support means and means for fixing the ejector plate, support means for central ejection board to hold a central ejection board at contact or near an ejector plate and fixing means of central ejection board, chosen so as to fix a central board in the adjustment position.
  • the central ejection board serves as a template for quickly and precisely placing the ejectors on the ejector plate.
