The container transport operation will be described below.

First, when the container (C) is transported to the end of the transport path of the conveyor (11) by the slat conveyor (11),
The elevating table (51) for raising the container rises, and the elevating table (51) raises the container (C) to the same height as the transfer plate (53). In this state, the endless chain (57) is driven by one pitch to move the container (C) up and down (51).
Transfer from above to the board (53). By repeating the above operation sequentially, the containers (C) are successively transferred from the slat conveyor (11) onto the transfer plate (53), and the container (C) transferred onto the transfer plate (53) is While sliding on the upper edge, move forward one pitch at a time.

Now, as shown in the figure, the movable base (55) is at the forward limit of its advance / retreat stroke, the lifting platform (52) is at the upper limit of its lift stroke, and the container (C) is above it. It is supposed to be put on each one. From this state, the elevating table (52) descends, and at the same time as or immediately thereafter, the movable table (55) retracts. When the lift table (52) reaches the lower limit, the pushing member (58) waiting at the backward end of the forward / backward stroke moves forward. As a result, the six containers (C) on each lifting platform (52) are moved from the lifting platform (52) to the belt conveyor (17).
Are extruded onto each conveyor belt (31). In this way, when a total of 24 containers (C) are placed on each conveyor belt (31), the pushing member (58) retracts and the lift table (52) starts to rise. On the other hand, when the movable platform (55) reaches the backward limit between the time when the lifting platform (52) descends and the time when it rises, the endless chain (57) is driven by one pitch for four pitches, Six containers (C) are delivered from the transfer plate (53) onto the four movable bases (55). Then, when the lifting table (52) that was rising reaches the upper limit, the movable table (55) moves forward, and again, as shown in the figure, there are six containers (C) each on the lifting table (52). It will be in a state of being put on each.

By repeating the above operation, the containers (C) that have been intermittently conveyed in 6 rows by the slat conveyor (11) are arranged in 4 rows and continuously conveyed by the belt conveyor (17). I will go.

EFFECTS OF THE INVENTION According to the present invention, the container transfer device allows the containers transported by the slat conveyor to be rearranged in a plurality of rows on the belt conveyor and transported, and the containers are transported during the transportation. The line is not disturbed.

Further, since the container transfer device is provided with the fixed table for temporary container placement and the movable table, the transfer operation can be continuously and efficiently performed.

Further, since the container transfer device further includes a container raising / lowering platform, a transfer plate and a container lowering platform,
The number of container rows conveyed by the slat conveyor and the number of container rows conveyed by the belt conveyor can be freely set without being restricted by each other.
