Definitions

  • the present patent application relates to a method for forming, maintaining and tensioning a band loop around the packaged goods of a banding machine with a band guide which limits the extent of the loop and a feed mechanism for unrolling, advancing and tensioning a band.
  • the invention further relates to a banding machine for binding packaged goods with a banding role, which is influenced according to the method.
  • a banding machine processes square, rectangular, round, trapezoidal or otherwise shaped objects by connecting them with at least one band, simultaneously or in succession, to form a stack.
  • the packaged goods can be hard or very soft.

  • the banderole is pulled out of the tape guide without moving mechanical parts and placed around the packaged goods.
  • the band guide with the sliding surface and side guides for holding up the band in loop form has only pneumatic means.
  • the present invention has for its object to provide a method and a device of the type mentioned, which works to form and maintain a loop of a banderole without mechanical support means, and further optimizes the formation of the loop.

  • the banding takes place in the usual way, with a working cycle of about 20 to 40 tapes per minute.
  • Multiple bindings can be carried out simultaneously by inserting the stack of packaged goods into a band guide or by arranging two or more band guides in a banding machine.
  • the "wandering", at least partially driven means according to the invention along the belt guide have two functions:
  • banderoles cause the banderole to be tightened as soon as it is pushed into the vicinity by the feed mechanism, in practice usually two superimposed, driven rollers with the band in between. Tightening in particular causes thin, flexible banderoles to be held up.
  • the transport movement of the feed mechanism is supported, in particular thin, flexible banderoles form a clean loop.
  • the drive movement of the feed mechanism and the rotating means along the belt guide are preferably coordinated with one another, they run approximately simultaneously and at approximately the same speed. Small deviations are not important, the compensation takes place continuously or at the latest when lifting immediately afterwards by tensioning.
  • the circumferential tel can be rotated along the belt guide via an additional gear by the drive of the feed mechanism. This ensures that the drive is synchronous, the speeds can be coordinated with each other using simple means.
  • the means running around the band guide can exert an attractive force on the band in various ways, which consists of an interaction-producing material or is coated accordingly.

Abstract

L'invention a pour objet un procédé pour le formage, le maintien et la mise en tension d'une boucle de bandelette autour d'un produit à emballer dans une machine d'application de bandelettes comprenant des moyens de guidage d'une bande limitant l'extension de la boucle et un mécanisme d'avancement servant à dérouler, à déplacer et à tendre une bandelette (18). Durant la phase d'avancement et après avoir atteint la position finale, la bandelette (18) est maintenue et entraînée sous la forme d'une boucle par des moyens de rotation (28a - 28i) exerçant une force d'attraction et au moins partiellement entraînés le long des moyens de guidage (12) de la bande, tout en étant toutefois automatiquement soulevée, lorsqu'une tension est exercée par lesdits moyens de guidage (12). Sur la machine utilisée pour le liage du produit à emballer au moyen d'une bandelette (18) et fonctionnant conformément au procédé, les moyens de rotation le long du guidage de la bande sont réalisés sous la forme d'au moins un organe convoyeur (28) flexible sans fin et/ou de galets au moins partiellement moteurs.
