Definitions

  • the machine shown in Figs. 1 and 2 is primarily a filling machine for handling flat bag members 2 that are supplied in a coherent row to a filling station 4, whereafter the filled bags are closed and separated from the coherent row.
  • a pre ⁇ fabricated bag web 6 prepared with a closed bottom edge 8 and with closed side edges along transverse separation lines 10 extending from the bottom to somewhat beneath the top edge of the bag web, such that the bag members 2 will be coherent at the top edge of the web, or whether such a preparation of the web takes place wholly or partly in the machine unit itself.
  • the filling station 4 successively receives flat bag members that are closed along the bottom and the sides, but open in the top in a manner such that the single bag members can be opened for filling by way of the carrier or transportation means cooperating with the top edge area of the bag members being operable to carry out an opening of this area.
  • a welding jaw or roller tool 26 produces a horizontal sealing line 28 between the upper ends of the separation lines 10, whereafter the top edge area of the bag web is cut be means of a vertically arranged knife 30, such that the filled bag members will successively be separated from the bag web for delivery as single units, e.g. for further conveying on a conveyor 32, Fig. 1.
  • This con ⁇ veyor may extend to underneath the filling station so as to support the loaded bag members all the way to their delivery.
  • the two applied chains 20 may be controlled so as to grip the top edges of the opposed sheet webs as these are fed to the machine, preferably from the supply reel, while also the optionally cut off top edge strip at the delivery end of the machine may be brought to leave the machine successively, merely by a brief re ⁇ leasing of the clamp pawls 40 at the rear sprocket wheels of the chains.
  • Figs. 4 and 5 illustrate a preferred design of the means, by which the opposed gripping chains at the fil ⁇ ling station can be moved away from each other and be rejoined prior to the stepwise further advancing of the bag web.
  • These means may simply consist of pivotally arranged guiding rail sections 50 which in a suitable co-controlled manner are pivotal between the positions shown in Figs. 4 and 5, by means of a suitable actuator system such as one or more working cylinders 52.
  • a suitable actuator system such as one or more working cylinders 52.

Abstract

Selon un procédé connu, on peut remplir une succession de sacs plats qui se présentent à un poste de remplissage sous forme d'une bande continue. Un dispositif est prévu pour faire avancer les parties marginales supérieures et opposées des sacs et pour écarter ces parties les unes des autres afin d'ouvrir les sacs. Lors de leur entrée dans le poste de remplissage, et de leur sortie de celui-ci, les bords latéraux des sacs sont fermés mais les fermetures ne s'étendent pas jusqu'au bord supérieur. On a prévu des chaînes de serrage parallèles (20) aptes à faire passer la bande de sacs fermés dans le poste de remplissage (4). Lorsque les chaînes s'arrêtent lors de l'introduction d'un sac (2) dans ledit poste, elles s'écartent l'une de l'autre pour permettre l'ouverture du sac. Dès que le sac est plein, les chaînes se rapprochent l'une de l'autre et emportent le sac pour permettre l'introduction dans le poste de remplissage du sac suivant. Ainsi, les fermetures latérales peuvent s'étendre presque jusqu'au bord supérieur et la bande de sacs peut être serrée en toute sécurité sans que son bord supérieur ne doive être épaissi ni plié. L'ouverture et la fermeture des sacs dans le poste de remplissage peut s'effectuer au moyen d'un système de commande simplifié (59, 52).
