Abstract
A bookbinding apparatus comprising: an adhesive container to store melted adhesive; a heater which heats the adhesive to melt; a stirring member to stir the adhesive in the adhesive container; and a control section which controls the operation of the heater and the stirring member so that after the heater has been turned off with the termination of a coating process, the stirring member continues stirring operation and stops thereafter.
Claims9
A bookbinding apparatus for coating adhesive on a sheet bundle comprising:
- an adhesive container that accommodates melted adhesive;
- a heater that heats the adhesive to melt;
- a temperature sensor configured to detect a temperature of the adhesive in the adhesive container;
- a stirring member that stirs the adhesive in the adhesive container;
- and
- a control section configured to perform the following operations:
- determine whether a coating of the adhesive is possible or not with reference to a threshold value temperature corresponding to a second temperature lower than a first temperature adequate for coating, based on the temperature detected by the temperature sensor;
- set a coating mode in which a temperature of the adhesive in the adhesive container is kept at the first temperature for the coating operation based on the temperature detected by the temperature sensor;
- set a shut-off mode in which the heater is turned off irrespective of the temperature detected by the temperature sensor;
- turn off the heater with a completion of the coating operation;
- continue a stirring operation by the stirring member for a period of time after the heater has been turned off in the shut-off mode;
- and
- stop the stirring operation by the stirring member thereafter.

- turn off the heater with a completion of the coating operation;
- continue a stirring operation by the stirring member for a period of time after the heater has been turned off in the shut-off mode;
- and
- stop the stirring operation by the stirring member thereafter.
