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).

A heat-sensitive adhesive label manufacturing device has a thermal head for heating and thermally activating the heat-sensitive adhesive layer of a heat-sensitive adhesive sheet, and a platen roller for conveying the heat-sensitive adhesive sheet between the platen roller and the thermal head to transport the heat-sensitive adhesive sheet in a transport direction. At least one discharge roller is disposed on a downstream side of the thermal activation section and is configured to undergo rotation at a peripheral speed different from a peripheral speed of the platen roller to convey the heat-sensitive adhesive sheet in the transport direction. A guide member is disposed opposite and spaced apart from the at least one discharge roller to provide a space therebetween along which the heat-sensitive adhesive sheet is conveyed by the at least one discharge roller without being sandwiched between the at least one discharge roller and the guide member.

There are disclosed a platen roller capable of inhibiting drop of an adhesive force of a thermally active adhesive layer, which is seen in a case where recording and thermal activating are performed with respect to a thermally active adhesive sheet having the thermally active adhesive layer on a backside of a recording surface of a sheet-like substrate, a method of manufacturing the platen roller, and a recording device and a sticking label printer which are provided with the platen rollers. As the platen roller for conveying the thermally active adhesive sheet having the thermally active adhesive layer on the backside of the recording surface of the sheet-like substrate, a platen roller is used which is subjected to a contact treatment to bring the surface of a roller portion into contact with a compound (a) containable as a solid plasticizer in the thermally active adhesive layer.
摘要:
A thermal head has heating elements that can be selectively driven independently from one another during a driving operation to directly heat, and thereby thermally activate, regions of a heat-sensitive adhesive layer of a heat-sensitive adhesive sheet while the heat-sensitive adhesive sheet is moved relative to the thermal head with the heating elements disposed in opposing relation to the respective regions of the heat-sensitive adhesive layer. All but at least one of the heating elements are selectively driven so that (a) a preselected region of the heat-sensitive adhesive layer disposed in opposing relation to each non-driven heating element is not directly heated, and thereby not directly thermally activated, by the non-driven heating element, (b) the regions of the heat-sensitive adhesive layer disposed in opposing relation to the respective driven heating elements are directly heated, and thereby directly thermally activated, by the respective driven heating elements, and (c) each preselected region of the heat-sensitive adhesive layer opposed to a non-driven heating element is thermally activated with heat transmitted from surrounding directly heated regions of the heat-sensitive adhesive layer of the heat-sensitive adhesive sheet.
摘要:
In a thermal activation method for a heat-sensitive adhesive sheet 2 which has a heat-sensitive adhesive layer 2a on one surface thereof and is to be stuck to an adherend 1, when a surface roughness of the adherend 1 is large, by heating the heat-sensitive adhesive layer 2a with large thermal energy, an adhesive is allowed to easily enter recesses 1a of the adherend. When the surface roughness of the adherend 1 is small, by heating the heat-sensitive adhesive layer 2a with small thermal energy, a viscosity of the adhesive is increased to thereby prevent the heat-sensitive adhesive sheet 2 from sliding and being peeled. The surface roughnesses of the adherends 1 may be classified for each material of the adherends 1, and the classified surface roughnesses may be judged according to each material of the adherends 1 to thereby determine the thermal energy.
