  • the magnets M50, M60 and the magnets M70, M80 repel each other at the gripping position or the open position of the PET bottle Q1, thereby gripping the lever member E10. Since the upper end corner E1b of the lever member E10 is pushed in by overcoming the urging force of the urging member biasing to the side, the lever member E10 can be turned to the open side.
  • the biasing member obtains a biasing force by a repulsive force or an attractive force of a magnet
  • a simple and inexpensive configuration without fear of cutting or the like can be provided.
  • the switching means is capable of not generating abrasion powder because of non-contact and suppressing the impact on the holding tool.
  • the left and right lever members E 10 are both pivotally supported by a single pin D 16, but the pin D 16 may be shared as described above. It is possible, and with such a configuration, it is possible to configure an inexpensive and simple gripping tool.
  • the present invention is most suitable for a conveyed product line changing apparatus that can surely prevent a conveyed product from falling even if the line is conveyed in a high-speed operation. Even if the conveyed product falls, it is suitable for a conveyed product line changing device that does not need to stop the line.

Abstract

Cette invention se rapporte à un dispositif servant à modifier le nombre de rangées d'articles transportés, et qui est capable d'empêcher de façon appropriée le retournement des articles transportés et de rendre ainsi inutile l'arrêt de la ligne de production, même si un renversement d'articles transportés se produit en amont. Ce dispositif comprend à cet effet plusieurs rails de guidage (C1) reliant une paire de chaînes de fixation (B1), des pinces (E1) fixées à des éléments coulissants (D1) bloqués coulissants et mobiles le long des rails de guidage (C1). Ainsi, des bouteilles en PET (Q1) suspendues et pincées par les pinces (E1) sont transportées et, par déplacement transversal des éléments coulissants (D1) à une vitesse prédéterminée, le nombre de rangées des bouteilles en PET (Q1) est modifié.
