Claims (1)

[Scope of Claim for Utility Model Registration] (1) A binaural clamping device that clamps both ears of the bag and a binaural clamping device that clamps the binaural parts of the bag and a vacuum adsorbing the center of the opening edge of the bag from both outer surfaces to separate them. In a bagging device equipped with an opening device equipped with a vacuum suction cup, two pairs of vertically protruding insertion rods are provided at positions that allow each suction cup to be inserted into the opening of the bag. Each set is equipped with one arm rod of equal size for each insertion rod, with a first axis parallel to the opening edge of the bag, relative to the machine frame. An insertion rod support part that vertically supports the insertion rod is pivotally connected to the tip of the arm rod by a second axis parallel to the first axis, and the insertion rod support part supports the insertion rod vertically. The parts are connected to each other by a parallel movement mechanism consisting of one of an endless belt type and a gear type, and the positions of these two sets of insertion rods are between the pair of vacuum suction cups when viewed from the plane. One suction cup is provided on each side of the vacuum suction cup, and the standby position is when the insertion rod approaches each group, and the vacuum suction cup is placed in a horizontal position where the two pairs of arm rods face each other. After the phases are separated, each arm rod is provided with a reciprocating drive source that rotates each insertion rod downward to a position where it engages with the opening edge of the bag, and returns to the original position after the stuffing is put into the bag. A bag filling device comprising a bag opening device characterized in that the device is connected to the bag opening device. (2) The insertion rod also serves as an electrical contact, and the stopper at the end of the downward stroke of the insertion rod serves as an electrical contact that can be contacted with the insertion rod, and the OR output for each insertion rod is generated by contact between these two contacts. A bagging device equipped with a bag opening device according to item 1 of the scope of utility model registration, characterized in that the signal is used as an input signal for stopping the operation of the bagging device.
