Description

[Detailed Description of the Invention] The present invention relates to an article dispensing device that automatically transfers articles such as packaged goods onto containers in fixed quantities.
A holding frame for holding a plurality of containers in a stacked manner is installed above the platform, and a container supply mechanism is provided to release and drop one container at the bottom, and a fixed amount of articles stored on the conveyor is transferred onto the platform. This invention relates to an improvement in an article dispensing device that allows articles to be transferred onto containers that can be dropped.

In the above device, it is necessary to provide a considerable distance between the container platform and the holding frame in order to provide a pusher or the like for transferring the articles on the storage conveyor. Since the container is dropped, the sound it makes when it lands on the ground causes noise, which is especially loud when the container is made of metal.

Furthermore, if the container is thin and lightweight, it may shake when dropped or bounce when it lands, causing misalignment.

In particular, when the storage conveyor is a roller conveyor that uses the weight of the articles to convey them, and the holding frame is installed in an inclined manner parallel to the conveyor,
Not only does the distance between the horizontal container platform and the holding frame become wider, which increases noise, but also the slanted storage conveyor and the horizontal container platform do not allow smooth delivery of fixed quantities of articles.

Therefore, even if the container platform is tilted parallel to the storage conveyor, the container will fall from the holding frame in an inclined state, and the weight will be applied to the lower end, easily causing misalignment. Accurate positioning is difficult.

In view of these circumstances, the present invention has been devised to ensure smooth and quick delivery and delivery of fixed quantities of articles and transport to subsequent processes in the conveyance/storage system using an inclined roller conveyor, as well as a pair of guides to guide containers from falling from the holding frame. It is an object of the present invention to provide an article dispensing device which can accurately position and land a container on a platform without making noise by guiding it by the vertical movement of a rod.

The present invention provides a swing mechanism for swinging the container platform from a horizontal position to an inclined position having the same angle as the product platform in the conventional article dispensing device described above, and a pair of guide rods are provided for swinging the container platform from a horizontal position to an inclined position having the same angle as the article platform. An elevating mechanism is provided that moves the container platform up and down from below the container receiving surface of the container platform to below the lowest container of the holding frame in conjunction with the movement mechanism, and the swing mechanism moves the container platform to an inclined position, and the lifting mechanism moves the guide rod. are moved to the raised position, the container at the lowest stage is dropped onto the guide rod by the container supply mechanism, and the guide rod is lowered by the lifting mechanism to place the container on the container platform. After placing the fixed amount of articles on the article platform, the pusher moves the fixed amount of articles onto the container on the container platform, and the swinging mechanism returns the container platform to a horizontal position to carry out the container.
