Conveying control device, conveying control method, conveying control program wherein the conveying control device comprises a subtractor, a tension command generation unit and a thrust correction unit

The present invention provides a conveying control device capable of controlling the tension of an object to be conveyed with high precision. The conveying control device (1) comprises: a subtractor (18) that acquires the tension of the conveyed object (3) to which tension is applied by the tension adjustment roller (243) from the tension detector (26); a tension command generation unit (17) that generates the tension command of the conveyed object (3); and a thrust correction unit (19) that corrects the thrust applied to the tension adjustment roller (243) in the opposite direction to the tension of the conveyed object (3) based on the difference between the tension obtained by the subtractor (18) and the tension command generated by the tension command generation unit (17). The thrust corrected by the thrust correction unit (19) is based on the air pressure of the cylinder (244) connected to the tension adjustment roller (243).
