Bag making and packaging machine

Abstract

The present invention has an object to provide a technology capable of reducing consumption current of a bag making and packaging machine making a bag and packaging a product with the bag. In order to accomplish the object, the bag making and packaging machine is provided with a seal jaw sealing a film to be packaging material, a heater part ( 201 F) heating the seal jaw, and a heater driving part ( 260 ) driving the heater part ( 201 F). Further, the bag making and packaging machine is provided with a motor driving part ( 270 ) to be a regenerative current supplying part supplying regenerative current generated in a motor to the heater part ( 201 F).

1 . A bag making and packaging machine making a bag and packaging a product using this bag, comprising:
 a sealing mechanism sealing packaging material;   a heater part heating said sealing mechanism;   a heater driving part driving said heaters;   a motor; and   a regenerative current supplying part supplying a regenerative current generated in said motor to said heater part.   
     
     
         2 . The bag making and packaging machine according to  claim 1 ,
 wherein when said regenerative current is supplied to said heater part, said heater driving part reduces a current applied to this heater part.
