[0038]

As described above, according to the invention of claim 1, 1
The time required for one cycle from the transfer of the package for one stage to the transfer of the package for the next stage is about 20 seconds. However, unlike the conventional case, the package of the package transfer device can be moved without moving the carriage. Compared to moving only the transfer section,
This is about 2 seconds shorter, a 10% time reduction. for that reason,
The operation rate of the package transfer system increases by about 10%.
Usually, since the package transfer system is operated unattended continuously for 24 hours, a 10% increase in the operation rate greatly affects productivity. Since the package transfer unit of the package transfer device does not need to mount a drive source for moving the package by the amount corresponding to the stacking deviation (D / 2), the weight of the package transfer unit is reduced. Since the transfer unit grips five or six packages P at the same time, the transfer unit becomes considerably heavy. Therefore, by reducing the weight of the package transfer unit, the package transfer unit can be moved at high speed. Further, since the means for moving the cart uses the cart transport device together, the number of parts and devices does not increase. Furthermore, since the movement of the transfer device is reduced, the mechanism and control of the transfer device can be simplified,
Parts can be reduced. Thereby, the cost can be reduced.

According to the second aspect of the present invention, it is possible to position the package cart at the time of transferring the package and to securely hold the package cart. Accordingly, the transfer unit of the package transfer device can stably transfer the package without failure.

According to the third aspect of the present invention, it is possible to accurately position the package cart when transferring the package.
