Definitions

  • the invention relates to a ner driving and an arrangement for operating condition monitoring of presses, in particular packet presses for the production of compacts, such as. B. from scrap and sheet metal waste.
  • shear packet presses according to DE 198 04 789 known, which consist essentially of a fill box with cutting edge, therein horizontally guided nerd with shear knife, a vertically arranged press box with ner nerd inside and a horizontally arranged transverse to the filler box with horizontally guided nerdd.
  • the filling box and the pressing box open into a common space which accommodates the package-like compact, the aforementioned package chamber.
  • the walls of the filling box, press box and package chamber form the housing of the shear packaging press.
  • the package chamber has an opening for the horizontally displaceable door through which the ejected compact passes.
  • the ner poets and the door are moved by hydraulic pistons / cylinders which are connected to a hydraulic drive system.
  • a first ner sealing step for nor compaction of the material fed to the width of the package by means of a compressor which is guided horizontally in the filling box, material possibly projecting beyond the ner poet being cut off at the cutting edge by means of the shear knife arranged on the ner poet,
  • a second ner sealing step for intermediate compression of the material pre-compressed to the package width to the height of the package by means of the compressor guided in the press box perpendicular to the filling box, then a third compression step for the final compression of the material to the final density or length of the package by means of the compressor horizontally guided transversely to the filling box in the package chamber, the finished package being ejected through the door from the package chamber after reaching the final density or length , exercised and done
  • Presses are not only understood to mean the type described at the beginning.
  • the demand for an improvement in the operating condition monitoring par excellence extends to presses, that is to say to machines in which a so-called stick-slip effect occurs as a result of the relative movement between a driven compressor and a press box or table receiving the compression pressure for the compact occurs.
  • the object of the invention is to develop a method and an arrangement for monitoring the operating state of presses, in particular packaging presses, in which damaging vibrational stresses are recognized prematurely and “seizing" of the machine parts involved in the relative movements are avoided.
  • Fig. 1 shows the schematically illustrated arrangement according to the invention using the example of a
  • the invention is explained according to the following embodiment in its basic arrangement and the principle of operation on a three-dimensional packaging press.
  • the packaging press 1 essentially consists of a press box 2.2 and a package chamber 2.3, as well as a first compressor 3.1 driven by a first piston / cylinder unit 6.1, a second compressor 3.2 and driven by a second piston / cylinder unit 6.2 a third compressor 3.3 (FIG. 2a) driven by a third piston / cylinder unit 6.3.

  • the invention can be implemented with relatively simple means, although its effect is associated with a significantly increased use value for the operator of generic machines, the retrofitting of presses already in operation also being unproblematic.

Abstract

L'invention concerne un procédé servant à surveiller l'état de fonctionnement d'une presse, notamment d'une presse à emballer (1). Ce procédé vise à éviter le grippage des parties de machine participant aux mouvements relatifs et comprend les étapes suivantes : a) on détecte des amplitudes de vibrations pendant le temps et/ou un déplacement d'un mouvement relatif ayant lieu entre au moins un compresseur (3.1, 3.2, 3.3) et/ou une porte (5.1) et la caisse de presse (2.2) dans le cycle du début à la fin du processus de pressage ainsi que pendant l'éjection de la pièce pressée et on prédéfinit une amplitude de vibration autorisée de la presse entière à l'intérieur du système de commande (16.2) en tant </= QU'éTAT NORMAL >/= pour les incréments de temps et/ou de déplacement des mouvements relatifs ; b) on génère une </= VALEUR D'ALARME >/= supérieure à la valeur maximale à </= L'éTAT NORMAL >/= , ainsi qu'une </= VALEUR DE COUPURE >/= supérieure à la </= VALEUR D'ALARME >/= ; c) on entre les deux valeurs limites de </= VALEUR D'ALARME >/= et de </= VALEUR DE COUPURE >/= pour chaque mouvement relatif approprié ou pour chaque incrément de temps et/ou de déplacement du mouvement relatif dans le système de commande (16.2) de la presse (1) ; et d) on pilote le fonctionnement de la presse au moyen du système de commande (16.2) avec affichage d'un signal si la </= VALEUR D'ALARME >/= et/ou la </= VALEUR DE COUPURE >/= est atteinte pendant le cycle du début à la fin du processus de pressage ou pendant le mouvement relatif approprié.
