A bag supply device receives large bags are retained in a stacked state on its mounting portions that are provided on chains. In addition, this bag supply device includes a horizontal support mechanism that supports the rear portion of the stacked large bags so that they can be raised and lowered in order to retain an uppermost surface of an uppermost large bag in a horizontal posture at a discharge position. The chains and the mounting portions are disposed such that the rear portion of the large bags hangs down. The horizontal support mechanism includes a roller that moves along the transport direction, and the uppermost large bag will be retained in a horizontal posture by moving the roller to support the rear portion of the large bags from below.

A bag packaging system includes a bag packager and a defect detection device that receives bags manufactured by the bag packager and conveys the bags while checking for defects. The defect detection device includes a first conveyor belt that is arranged below the bag packager, a line sensor that is arranged adjacent to a downstream end of the first conveyor belt, and a controller. The line sensor sends a detection signal when it detects an object that is conveyed by the first conveyor belt. The controller stores the size of a proper bag that is being manufactured. The controller finds a defective bag based on the size of the proper bag, the conveying speed of the first conveyor belt, and duration of the detection signal from the line sensor. The defect detection device can detect defects in bags promptly after the bags are manufactured by the bag packaging machine.

A seal inspecting machine for inspecting bagged products to determine the presence or absence of a seal abnormality in each bagged product being transported by a transport conveyor includes a presser unit and a servo motor for driving the presser unit to sandwich the bagged product G between the presser unit transport conveyor . The servo motor itself has a capability of detecting a reactive force acting on the presser unit or a displacement of the presser unit that occurs as a result of contact with the bagged product, where any failure of the bagged product to exert a sufficient reactive force or displacement resistance is considered evidence of a seal abnormality being present in such bagged product. With this seal inspecting machine, seal check of the bagged products can be efficiently and inexpensively carried out.
