  • the diameter of the cylindrical body can be easily changed by simply operating the servo motor 87, so the setup change work can be performed efficiently.
  • the opening shape of the former is a general circular shape, the articles can be efficiently supplied to the packaging device 5.
  • the shape of the cylindrical body 81 and the opening degree of the gates 82 and 83 are automatically adjusted so that the falling length of the article becomes shorter. Since it can be changed, we can realize weighing packaging at a higher speed.
  • the lower opening 8c of the hopper 8 is made smaller than the receiving opening 51 of the packaging device 5 in plan view, or an article stored in the storage portion 8b is received by the receiving opening 51 of the packaging device 5. Since the shape of the cylindrical body 81 and the opening degree of the gates 82 and 83 can be changed so that the lateral width is smaller than the subsequent article dropping path, the articles are packed together in the reservoir 8b. By storing and suppressing the spread expansion of the articles at the time of dropping, it is possible to prevent defects such as seal stagnation in the packaging device 5, and to reduce the contact resistance of the articles with respect to the receiving opening 51 if the drop length of the articles is shortened, The article can be dropped in a short time.
  • the diameter of the cylindrical body and the change in the gate opening are automatically performed by the control unit of the weighing device according to the information about the receiving opening and the article dropping path. It may be performed manually while confirming the supply status of the article. Further, the information regarding the receiving opening 51 and the article dropping path may be confirmed by an operator who does not automatically obtain the information from the packaging device 5 and input.

Abstract

L'invention concerne une trémie qui stocke des articles en provenance d'une ouverture supérieure et qui les décharge depuis une ouverture inférieure, ainsi qu'un dispositif de mesure et de conditionnement comprenant ladite trémie. la trémie de l'invention peut regrouper les articles à décharger de manière compacte et, simultanément, empêcher l'engorgement de ceux-ci. Ladite trémie reçoit les articles depuis l'ouverture supérieure, les stocke dans une section de stockage formée par fermeture de l'ouverture inférieure par une porte, et décharge les articles stockés vers le bas par ouverture de la porte. La porte comprend deux éléments de section transversale en L montés rotatifs de façon à être positionnés l'un en face de l'autre. Les éléments sont caractérisés en ce que la section transversale en L est formée par une paroi de corps dont les extrémités sont proches l'une de l'autres afin d'obtenir une forme de toit renversé lorsque la porte est ouverte, et par des parois latérales s'étendant depuis les extrémités pour recouvrir les extrémités latérales de la paroi de corps positionnées l'une en face de l'autre lorsque la porte est fermée.
