    Abstract: A product weight calculation system includes an accommodation section, a door portion that switches between a closed state and an open state, a weight detector that detects a weight of the products accommodated in the accommodation section and outputs an output value, a door detector that detects a state of the door portion, and a product weight calculation unit that calculates a weight value of a product taken out from the accommodation section based on a difference between a first output value and a second output value when an output value of the weight detector decreases from the first output value and becomes the second output value in a case where it is determined from a detection result of the door detector that the door portion is transitioned from the open state to the closed state, and sets an output value after the calculation as a new first output value.

    Abstract: Provided is a stretch wrapping machine that can stably convey film even in a case where, for the purpose of wrapping, a holding component that holds the film is provided separately from belts for conveyance. The stretch wrapping machine is equipped with conveyance devices (22) having belt conveyance units and belt pressing mechanisms, a clamp device (23), a wrapping station, and a control device (9). At the wrapping station, product is pushed against film held by the clamp device (23), and the product is wrapped by the film. The belt conveyance units have upper belts and lower belts that sandwich end portions of the film. Pressing members (221e) of the belt pressing mechanisms apply force to the upper belts so that the force with which the upper belts and the lower belts sandwich the film increases. Additionally, the control device (9) controls the belt pressing mechanisms so that during conveyance of the film the force resulting from the pressing members (221e) acts on the upper belts and so that after conveyance of the film the force resulting from the pressing members (221e) that had acted on the upper belts is cancelled.
