Abstract:
1. A label supplying device comprising: a label base material delivery unit for continuously delivering a label base material in a form of an elongated strip; a label base material cutting unit for cutting, at a predetermined cut pitch, the label base material delivered by the label base material delivery unit, to form cylindrical labels in a state of a folded sheet; a belt transfer unit for transferring the cylindrical labels one by one to a label supply position; and a label edge separation unit for separating overlapping edges of an end of each of the cylindrical labels in the state of a folded sheet during the transferring of the cylindrical labels by the belt transfer unit: wherein the belt transfer unit includes a pair of feed belts for transferring the cylindrical labels while holding the cylindrical labels by suction, the feed belts being arranged parallel to each other with a predetermined space therebetween, wherein the label edge separation unit includes: wherein the controller controls the servomotor such that a peripheral speed of the speed variable roller or movement speed of a speed variable belt of the speed variable belt mechanism is equal to a movement speed of the paired feed belts of the belt transfer unit when portions of each cylindrical label other than one end passes through a sandwiching portion between the first free roller and the speed variable roller or the speed variable belt mechanism, whereas the controller controls the servomotor such that the peripheral speed of the speed variable roller or movement speed of the speed variable belt of the speed variable belt mechanism is different from the movement speed of the paired feed belts of the belt transfer unit when said one end of the cylindrical label passes through the sandwiching portion between the first free roller and the speed variable roller or the speed variable belt mechanism.
