Abstract

PURPOSE:To cope with the size or specification of a bag to be formed, or the properties of a packaging material, prevent a melting loss from taking place at the time of non-operation, and make the filling cylinder detachable. CONSTITUTION:A vertical sealing unit 20 is made separatable from a filling cylinder 30 when the filling cylinder is replaced, by a swing arm 2 which swings with a pivotal pin 3 as the pivot, and the vertical sealing unit 20 is made positionable at a location in response to the diameter of the filling cylinder 30. The pressing of a sealing heater 28 is releasable by a cylinder 9 for heater- separation when the device is not operated, and the position of the sealing heater 28 is made variable by a knob 17 for sealing position alteration. In addition, the angle of a vertical sealing belt 27, which comes into contact with a packaging material (s), is made changeable by turning a sleeve 13.

The vertical edges overlapped with each other are sealed with a heater for vertical sealing, and a heater for horizontal sealing arranged below the filling cylinder is used to separate the portion that touches the top of the bag and the portion that touches the ground of the next bag. A bag-making and packaging machine that seals at the same time, that is, a packaging machine called a vertical pillow packaging machine, usually uses a belt-type vertical sealing mechanism to continuously fill and package the contents. Is configured to do so.

容易にする。By the way, when the required number of lots have been packaged and the filling cylinder 30 needs to be replaced in order to form a bag of a different size, the lock mechanism (not shown) is released. In addition, the swing arm 2 is swung largely counterclockwise in the figure with the fulcrum pin 3 as a fulcrum, and the front surface of the filling cylinder 30 is released to facilitate the attachment / detachment work.

未然に防止することができる。As described above, according to the present invention, the arm member for supporting the vertical seal member is pivotally supported so as to be largely separated from the filling cylinder, and the vertical seal is attached to the arm member. Since the means for adjusting the movement of the member according to the diameter of the filling cylinder and the means for moving the vertical seal member to and from the packaging material are provided, it is easy to replace the filling cylinder according to the size of the bag to be molded. In addition, it is possible to position the vertical seal member in line with this cylinder, and further to prevent accidents such as melting by separating the vertical seal member from the packaging material when the operation of the device is stopped. it can.
