Abstract

PROBLEM TO BE SOLVED: To prevent a failure in welding a binder from occurring in an ultrasonic welding type bag binding machine using a gate-shaped binder. SOLUTION: The apparatus for welding a binder is equipped with a displacement sensor such as a magnetic scale 26 for detecting a distance between an ultrasonic vibrator 22 and a cradle 24. The binder 12 interposed between the ultrasonic vibrator and the cradle is melted when welding, and when the distance between the vibrator and the cradle becomes a specified value, a control section cuts off power supply to the vibrator. Thus a thickness of a welded portion of the binder is controlled to be constant.

2. Description of the Related Art A bag binding machine that binds bags containing foods or the like is used. The binding device used in the bag binding machine is a gate-formed product made of a resin plate. When the mouths of the bags are bundled and inserted into the guide groove of the bag binding device, the binding device sent by the feeding device causes the convergence portion of the bag to be closed. The two legs of the tying tool are crossed by the arm, and both legs are crimped or welded to tie the bag.

不良が発生することがある。The ultrasonic welding type bag binding machine welds the binding device by driving the welding device for a certain period of time. However, due to the tolerance of the sheet thickness of the binding device and the level of the environmental temperature, etc. There is a problem that the thickness of the welded portion sandwiched between the ultrasonic transducer and the cradle changes.If the thickness of the welded portion becomes extremely thin, the bonding force is insufficient and the welded portion is easily peeled off by external force.

Conversely, when the thickness of the tying tool is thick or at a low temperature, or when moisture or dust adheres to the surface of the tying tool or the like, the energization time is insufficient and welding failure may occur. .
