A plurality of holding units, which are provided in a moving device that moves between the packaging units for packing the boxes, and are arranged in a row in the front-rear direction to hold the fruits and vegetables, are arranged in parallel. The distance between the holding bodies in the holding unit, the relative position in the front-rear direction of the holding bodies adjacent to each other, and the distance between the holding units can be changed.
Further, in the respective changed state, the arrangement changing device in which the interval between the holding bodies in each holding unit is expanded so that the fruits and vegetables held in each holding body are in a staggered arrangement with a gap between the adjacent ones. The staggered array in which the adsorbed and held fruits and vegetables are to be packed during the movement after adsorbing and holding the fruits and vegetables arranged in the predetermined arrangement on the aligning device by the arrangement changing device. However, by arranging the fruits and vegetables in a state in which they are connected to each other, the occupying area of the aligning device can be reduced and the device can be simplified, and the fruits and vegetables can be staggered. By packing in a box-like arrangement, it is possible to use a box that has a comparatively small area for storing fruits and vegetables, as compared with a box in which fruits and vegetables are packed in a row and column. While the fruits and vegetables are absorbed and held by the holder, the distance between the holders in each holding unit is expanded during the movement to the packaging section, and the fruits and vegetables held in each holder have a zigzag space between them. Since the fruits and vegetables are separated from each other and do not press against each other even if an impact due to vibration or the like is applied to the holder during the movement, the fruits and vegetables do not fall off the holder. It can be reliably boxed, and even in soft fruits and vegetables, it does not damage the fruits and vegetables such as scratches and scratches, and also in a staggered array tray pack in which the fruit and vegetable containing recesses have a slight interval between adjacent ones. It has the effect of being able to pack fruits and vegetables.

Further, the present invention provides a drive device for moving one holding unit (holding body) located at the end of the plurality of holding units (the same applies to the holding body) in the forward and backward directions, and the plurality of holding units (holding units). The adjacent units of the body are connected to each other by loosely fitting the protrusions provided on the other to the elongated holes of the connecting member that fix the adjacent ones to the holding units at the ends. Since it has a connecting means that can be changed in series in association with the movement of the (holding body),
An excellent effect is obtained in that the mechanism for changing the interval between adjacent objects is simple.
