[0003]

However, since this work is a standing work if it is performed repeatedly and continuously, the work becomes extremely heavy labor for the worker, and the viewpoint of the working environment and the retention rate of the worker are poor. Since the operation is monotonous, there is a possibility that the operation process becomes complicated.

In view of such circumstances, Japanese Patent Publication No. 4-82
Japanese Unexamined Patent Publication No. 87 discloses a device in which a required number of stacked sheets are accommodated in a bag-shaped member, the bag-shaped member in which the sheets are accommodated is gripped by a claw member, and the opening of the bag-shaped member is sealed. Further, Japanese Patent Application Laid-Open No. 61-114956 discloses an apparatus for cutting conveyed sheets at regular intervals and stacking a required number of cut sheets. However, each of the above disclosed technologies has the following problems. First, since the technique of Japanese Patent Publication No. 4-8287 has a configuration in which a sheet is inserted into a tubular bag and the end portion is sealed in a state in which the sheet is inflated by the sheet, the tubular shape is changed to a bag shape. It is necessary to allow a large margin for sealing later, and the size of the bag is wasted. In addition, a configuration is disclosed in which the sheet is once housed in the caser and then packed in the bag. However, when the sheet is a polyethylene bag or the like, air enters the bag to increase the thickness, which makes it difficult to house the sheet in the caser. . further,
Because the mouth of the bag is opened by inserting the core,
It is necessary to change the core according to the size of the bag, and since the core insertion into the first bag cannot be performed automatically, the core must be inserted manually every time the operation is interrupted. It was troublesome and workability was bad. Also, JP-A-61-1149
Although the technique disclosed in Japanese Patent Publication No. 56 is excellent as an apparatus for sequentially cutting a large number of sheets, the work of packing the sheets in a bag could not be performed. Therefore, in view of the above situation, the present inventor is a packaging device capable of automatically storing a required number of sheets in a polyethylene bag and sealing the opening of the polyethylene bag with an automatic machine. We continued our research on a packaging device that can be used, can use bags efficiently without waste, and improve work efficiency.
