| 1. A packaging system configured to package a product by supplying the product onto a lifter by means of a supply device,
lifting the product up to a packaging station, and covering the product with a film on the top surface thereof, the packaging
system comprising:
a conveying unit configured to convey the product onto the lifter by contacting a rear end of the product on the supply device
in the conveying direction;
a detection unit configured to detect a first amount of misalignment of the product in a width direction that is orthogonal
to the conveying direction before the conveying unit contacts the rear end of the product, and to detect a second amount of
misalignment of the product in the width direction after the conveying unit contacts the rear end of the product; and
a control unit configured to control each unit of the packaging system in accordance with the first and second amounts of
misalignment detected; wherein the control unit is configured to correct the misalignment of the product in the conveying
direction by driving the conveying unit to convey the product in the conveying direction in accordance with the amount of
misalignment in the conveying direction that is detected by the detection unit; the detection unit is configured to detect
the position of the rear end of the product and the position of a contract member that comes into contact with the rear end
of the product, and to detect the amount of misalignment of the product in the conveying direction based on the position relationship
detected between the contact member and the rear end of the product.
