Buffer means for containers and method for buffering containers

摘要

A buffer means and a method for buffering containers, in particular in a container handling apparatus, like for example bottles in a bottle filling apparatus, is described. The buffer means comprises at least a first conveyor track. Furthermore at least a second conveyor track is provided, which is drivable along a second transport direction. The first conveyor track and the second conveyor track are parallel to each other and form a buffer module. A transfer device transfers the containers from an infeed conveyor track onto an outlet conveyor track of the buffer module. By means of a sliding device the required buffer capacity of the buffer means can be set. Between the infeed conveyor track and the outlet conveyor track of a buffer module at least two further drivable transfer conveyors are provided. Thus a closed surface of the buffer module is created.

主权项

1. A buffer means for containers operating according to the first in-first out principle, comprising:
at least one infeed conveyor track drivable along an infeed direction; at least one outlet conveyor track drivable along an outlet direction; a buffer module, having a front module, intermediate module and an end module, is formed by the at least one infeed conveyor track and the at least one outlet conveyor track which are arranged parallel to each other and having a width; at least one intermediate module is arranged between the front module and the end module; a sliding device for sliding a transfer device in parallel along the infeed conveyor track or the outlet conveyor track, respectively, in dependence on a required buffer capacity in the buffer means; a transfer device with an outer guide, so that the containers are transferrable from the infeed conveyor track to the outlet conveyor track of the respective buffer module; a louver band between the infeed conveyor track and the outlet conveyor track, which is attached to either side of the sliding device; and, a drive mechanism for the sliding device; wherein a drivable transfer conveyor and the sliding device each have their own drive mechanism so that the drivable transfer conveyor and the sliding device are individually controllable, and wherein said drive mechanism for the drivable transfer conveyor drives an endless chain which comprises the outlet conveyor track and the infeed conveyor track.
