Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cup feeding device, and more particularly to a cup feeding device that intermittently feeds bottomed containers such as food storage cups onto an endless conveying device that moves at a constant speed. It is something.

B. Prior Art Various cup filling devices are used to automatically fill liquid contents such as alcoholic beverages and fruit juices, and solid contents such as instant foods and powdered seasonings into cups. These cup filling devices are generally configured to fill and seal a predetermined amount of contents into a cup-shaped container on an endless conveying device that moves at a constant speed. 7. Since there are many types of contents that can be filled into cup-shaped containers, it is necessary to configure the filling line so that the shape and capacity of the cup-shaped containers can be changed according to the type of contents. There is.

In order to achieve this purpose, in the cup feeding device located upstream of the endless conveying device, the feeding conditions of the cup shaped container by the cup feeding mechanism must be adjusted in response to changes in the shape and dimensions of the cup shaped container. It is necessary to be able to adjust the However, conventional cup feeding devices are hardly equipped with such a mechanism for adjusting cup delivery conditions.
Furthermore, even if such a device were provided, the structure would be complicated and adjustment would take a long time, making it extremely difficult to respond quickly when changing the contents to be filled or the cup capacity. That is, in the conventional cup filling line, the entire filling line including the cup feeding device must be stopped for a long time in order to adjust the cup delivery conditions every time the content or cup capacity is changed. Significant constraints were recognized in improving the productivity of the filling line. In the worst case, when changing the cup delivery conditions,
The previously used cup feeding device must be replaced with a new cup feeding device adapted to the shape and dimensions of the new cup, which simply reduces productivity in filling lines that involve frequent changeovers of contents or cups. This has caused various inconveniences such as not only a decline but also a decline in equipment investment efficiency and a reduction in labor-saving effects.

OBJECTS OF THE INVENTION The main object of the present invention is to provide a novel cup feeding device capable of solving the above-mentioned problems unresolved in conventional cup feeding devices and filling lines.

Another main object of the present invention is to provide a cup feeding device that is simple in structure and highly reliable in operation.

To explain in more detail, below the magazine (14) that stores the nested cups (1), there is a spiral YR that engages with the flange (1゛) formed on the upper edge of the cup (1). A set of four cup take-out cams (2) having (3) bored in the peripheral wall surface (2゛) are arranged so as to surround the falling path of the cup (1). ) is rotatably supported by a belt wheel (16) and a gear train 07) (1
A drive mechanism (D) consisting of B> and the like is connected in series. The drive mechanism (D) for the cup take-out cam causes simultaneous rotation of a set of four cup take-out cams (2) arranged so as to surround the falling path of the cup (1), and changes the arrangement phase. Flange (1') by synchronized spiral grooves (3)
The held cups (1) are separated one by one from the cup stack and are intermittently fed onto the endless conveying device (C) located below and moving at a constant speed using the rotation of the cup take-out cam (2). It is something to do. It is necessary that the arrangement position of the cup take-out cam (2) of the above-mentioned 4 (II Liff) can be adjusted to match the outer diameter dimension of the flange (1゛) portion of the cup (1). It is necessary to adjust the height of the cup take-out cam (2) from the endless conveyance device (C) according to the change in the height dimension of (1).

In other words, the width dimension of the falling path of cup (1) is
