Description

[Detailed description of the invention] As far as the cliff goes! The present invention relates to a paper pack filling machine, and more particularly to a device for forming and sealing paper containers used for filling liquid contents such as alcoholic beverages, fruit juices, or milk.

Conventionally, various filling plants have been proposed in which a paper pack forming device and a sealing device are attached to a filling line for blood-like contents, and the final product is produced in a continuous manner. In such a liquid content filling line, which is well known as an automatic filling process,
Although it is necessary to adjust the operating speed of the filling line according to the type and filling volume of the liquid content to be filled, the filling capacity of the liquid content and the filling capacity of the liquid content can be maintained under any operating conditions. If the paper pack forming and sealing capabilities are not balanced, waiting time will increase and the operating efficiency of the filling line will decrease. On the other hand, a known paper pack filling machine installed in a filling line has a paper pack temporary folding device, a sealing device for the opening of the paper pack, and a liquid content filling device arranged on a single plane. things dominate.

When installing a paper pack filling machine such as the above-mentioned paper pack filling machine on a high-speed filling line where the final product is sent out and the speed reaches, for example, 30 pieces per minute or more, it is necessary to Since the filling process proceeds in a fully automatic manner according to the filling program input to the numerical control device, unless a special accident occurs, the filling capacity of liquid contents and the capacity of forming and sealing paper packs can be maintained relatively easily. Can be balanced. In addition, from the standpoint of improving the operating efficiency of the filling line, in such a high-speed filling line, the paper pack forming device, the liquid content filling device, and the paper pack opening sealing device are installed on a single plane. They are often aligned.

On the other hand, in low-speed filling lines where the final product delivery speed is, for example, 3 to 5 pieces per minute, the filling process proceeds in a semi-automatic manner that often requires manual operation by workers. ``Compared to high-speed filling lines, there is a greater need to create an equilibrium between the filling capacity of liquid contents and the ability to form and seal paper packs, and from the standpoint of simplifying the configuration of the filling line, it is possible to do so. It is desired to adopt a device layout as compact as possible. However, in the case of conventional low-speed filling lines, the paper pack forming and sealing equipment used for high-speed filling lines is directly used, so the capacity of the repurposed equipment is not compatible with the filling capacity of liquid contents. This has significantly hindered the improvement of operating efficiency, especially in filling lines that require manual operation.In addition, the paper pack forming equipment, the liquid content filling equipment, and the paper pack opening sealing equipment are all on the same plane. Due to the alignment, saving of floor space of the filling line was restricted.

The main object of the present invention is to provide a paper pack filling machine capable of eliminating the above-mentioned disadvantages observed in conventional filling lines for liquid contents, especially low-speed filling lines where the number of items filled per unit time is relatively small. It is about providing.

C1. Effects of the Invention As can be understood from the above description, the filter paper puncture filling machine according to the present invention allows a part of the paper pack forming process, that is, the insertion, mounting, extraction, and removal of the paper pack, to be performed manually by the operator. When used in a low-speed filling line for liquid contents carried out by a company, it greatly contributes to improving the operating efficiency of the low-speed filling line. When the device of the present invention is installed in a low-speed filling line where the filling capacity per unit time is relatively low, it is easy to create an equilibrium state between the ability to form and seal paper packs and the ability to fill liquid contents. Also, the first radial arm and the second radial arm are arranged coaxially in two stages, upper and lower,
By adjusting the mounting position of the paper pack on these radial arms so that a phase angle of 90° or more and 270° or less is formed between the two radial arms, the installation space of the filling line can be compared to conventional equipment. It is possible to significantly reduce costs and improve the operability of the paper pack filling machine. Therefore, the present invention can exhibit remarkable effects in improving productivity and reducing product costs in a liquid content filling line for manufacturing paper pack products with relatively small lofts.
