摘要:
A thermal activation device has a thermal activation head that thermally activates a heat-sensitive adhesive layer of a sheet material having a printing layer on one surface of a sheet-like base material and the heat-sensitive adhesive layer formed on the other surface thereof. A platen roller conveys the sheet material and is disposed in pressure contact with the thermal activation head so that the platen roller and the thermal activation head apply a holding force on the sheet material. A pair of conveyor rollers hold and convey the sheet material and are disposed on a downstream side of the thermal activation head in a conveying direction of the sheet material. A holding force applied on the sheet material by the pair of conveyor rollers being larger than a holding force applied on the sheet material by the platen roller and the thermal activation head.

Provided is a thermal activation apparatus in which a discharge path of a heat-sensitive adhesive label is not adversely affected by adhesive residue. The thermal activation apparatus comprises a discharge mechanism (15) for completely discharging a heat-sensitive adhesive label with its heat-sensitive adhesive agent layer formed on the back side heated by a thermal head from between the thermal head and a platen roller. The discharge mechanism (15) is structured such that two shafts (15b and 15c) made of metal are passed through a plurality of belts (15a) which are endless elastic members, the two shafts (15b and 15c) are disposed at given intervals from each other and in parallel with each other, and the two shafts (15b and 15c) are rotatably supported. By rotating one of the two shafts (15b and 15c) as a driving shaft, the belts (15a) rotate to be able to discharge the heat-sensitive adhesive label (1) fed thereonto.

摘要:
A heat-sensitive adhesive sheet is thermally activated thoroughly at both ends in a conveying direction and unnecessary heating from heat accumulated in a platen roller is avoided. Driving of heating elements (10) of a thermal activation thermal head is started (T3) before the front end of a heat-sensitive adhesive sheet (1) in a sheet conveying direction enters between the thermal head and a platen roller (12) (T2). A heat-sensitive adhesive layer is thermally activated until the heat-sensitive adhesive sheet is sent past the heat-sensitive adhesive sheet (1). Driving of the heating elements (10) is stopped (T6) after the rear end of the heat-sensitive adhesive sheet (1) departs from between the thermal head and the platen roller 12 (T5). The time period from the start of driving of the heating elements (10) to the entrance of the front end of the heat-sensitive adhesive sheet (1) between the thermal head and the platen roller (12) (T2-T3), and the time period from the departure of the rear end from between the thermal head and the platen roller (12) to the end of driving of the heating elements (10) (T6-T5), are each set shorter than the one it takes for the platen roller (12) to rotate once.
摘要:
A heat-sensitive adhesive layer is thermally activated to develop satisfactory adhesion at improved energy efficiency. A thermal activation thermal head is driven in sync with movement of a heat-sensitive adhesive sheet conveyed, and chosen heating elements stop being driven at a given timing. For instance, while moving the heat-sensitive adhesive sheet, driving of three heating elements (10B, 10F and 10J) and driving of two heating elements (10D and 10H) are alternately stopped whereas five heating elements (10A, 10C, 10E, 10G and 10I) are driven all the time. Supposing that the entire surface of a heat-sensitive adhesive layer is gridded to form a matrix, a region (15A) that is directly heated by none of the opposing heating elements 10 is placed regularly in a manner that makes its surrounding regions (15B to 15I) heated directly by the opposing heating elements. The directly heated regions (15B to 15I) are activated by the opposing heating elements (10) whereas the indirectly heated region (15A) is activated by heat transmitted from the surrounding regions (15B to 15I).
