There was no. In addition, there were devices that sucked and held sheets such as cardboard sheets and transported them.The problem that the fist invention aims to solveIn the past, in a sorting and shipping plant for fruits of deciduous fruit trees such as apples, peaches, pears, and persimmons, packaging was not done in boxes. This is done using human sign language and requires a lot of manpower, so it is desired to save labor. When automating this process with a machine, the traditional way of packing the fruit into boxes by hand is that for persimmon Fuyu fruits, for example, the typical 15K
Put a flat cardboard sheet on the bottom of the g-packed box,
- Pitchers were lined up, a cardboard sheet was placed on top of the pitchers, and then the pitchers were stacked in 3 to 4 tiers, with a second tier, then a third tier, with a sheet between each tier to serve as a partition wall. In addition, apples, peaches, pears, etc., were packed in rows using resin or paper sheets with four parts arranged vertically and horizontally in the same way as for persimmons, so automated boxing is also used in the past. It is desirable to pack the fruit and sheets in the same way, but it takes time to pack the fruit and sheets separately and then pack them into a cardboard case.
