Description

  The present invention relates to a bag delivery device in a bag making and packaging machine.

  As a conventional bag making and packaging machine, for example, in Japanese Patent Application Laid-Open No. 2002-36392, a film fed from a film roll is folded into two with a side edge in the longitudinal direction by a molding device, and a bottom seal is attached to the film. Form a continuous bag body with side seals, separate the bag body into a predetermined bag width and produce two bags at a time, and feed two sheets from the bag making apparatus And a packaging device for supporting the bag in a suspended manner with two adjacent grippers with the bag mouth facing up, and filling the bag supported by each grip pair simultaneously with the contents to seal the bag mouth. A constructed bag making and packaging machine is disclosed.

  In the bag making apparatus described in the above-mentioned published patent gazette, a bag produced in a vertical orientation with the bag mouth facing up may be sent to the packaging device side by the bag delivery device as it is. The structure is simplified. However, since the film is drawn up with the inner side of the bag facing upward and the folded bag mouth is facing upward, there is a possibility that dust floating in the air may adhere to the inner surface of the bag. Bags made of thin film are weak, so it can be said that it is difficult to stably carry out heat sealing and separation work when making bags one by one. From these things, the bag making and packaging machine provided with the bag making apparatus for folding the film drawn in the longitudinal direction with the bag inner side facing down in the longitudinal direction and the bag mouth side in the lateral direction to make a bag Japanese Patent Application Laid-Open No. 2004-244085.

  The “bag delivery device” described in the latter published patent publication includes two sets of suction cups provided so as to be swingable in a vertical plane perpendicular to the film feeding direction, and the suction cups in a downward downward position and an upward direction. The suction cup swinging mechanism that reciprocates between the horizontal position and the suction position of the suction cup sucks the bag surface of the horizontal bag when it is in the downward position, and when it comes to the horizontal position, the bag is raised vertically all at once. In order to cope with different lengths of the bag, the position of the swing axis of the suction cup is adjusted in a direction perpendicular to the film feeding direction in a horizontal plane. Also, in this device, when the two sets of suction cups swing from the downward position to the horizontal position, the distance between the two sets of suction cups is increased to match the distance between the two sets of grippers of the packaging device, and in the opposite direction. When swinging, an interval adjusting mechanism is provided that narrows the interval between the two sets of suction cups to match the pitch of the two bags at the receiving position.

When changing to a bag having a different bag width in the bag delivery device, the distance between the two suction cups is adjusted by adjusting the raising / lowering position of the drive rod. However, the adjustment method is unknown because it is not described in detail, but it is presumed that it is probably not automated. In addition, since the interval between the suction cups provided for each set is constant and fine adjustment cannot be performed according to the size of the bag width, a thin bag with a large bag width is particularly stable. It can be said that it is difficult to supply the gripper at a high speed of about 120 sheets per minute.
