Furthermore, if the temporary placing operation of the new packaging base paper 100 is carried out using a spare time, the subsequent replacement work between the used base paper of the packaging base paper supply equipment 1 and the new packaging base paper 100 is automatically performed. And the transfer work is completed in a short time. Therefore, it was possible to make full use of the packing capacity of the automatic packing line, and production efficiency was remarkably improved.

In the above embodiment, the base paper transfer device 14 is used.
, The actuators using the fluid cylinders 25, 29, and 42 as the actuators such as the tilting actuator in (1), the swinging actuator in the stopper device, and the rotating actuator of the shaft support member (40) in the base paper take-out / supply device (31). Instead, other known actuators such as motors and screws may be used.

Although the stopper device is of the swinging type, it may be of a linear moving type that can move forward and backward. Further, a gear driving method may be used as the turning drive method of the turning arm. In addition, instead of the chain drive system, the base paper lifting / lowering device may be a wire drive system, a drive system combining a nut and a screw shaft, or a system using a fluid cylinder.

In the above embodiment, the turret type is used as the wrapping paper supply equipment. However, the wrapping paper changing apparatus of the present invention can be suitably applied to other types of wrapping paper supply equipment.
