You can also

Here, the clamp 121 is formed on both sides of the third pneumatic cylinder (121-4), the elastic member (121-5) for pressing the other side of the bag (1) crimped to a pair of pressing bar (121-2). For example, it may further include an elastic member 121-5 made of a spring. That is, the elastic member 121-5 can effectively prevent the warpage of the bag 1 compressed between the pair of pressing bars 121-2. For example, the elastic member 121-5 prevents warping of the bag 1 due to vibration or oscillation that may occur when the bag moving part 120 moves toward the nozzle 12 of the hopper 40 of the bag 1. By doing so, one side of the sealing portion 3 of the bag 1 can be accurately inserted into the hopper nozzle 12.

Accordingly, as described above, the unit packaging efficiency can be further improved by changing the shape of the bag 1 so as to be inserted and fixed to the hopper nozzle 12 to facilitate the unit packing of the bag.

By rotation, it translates to the hopper nozzle 12 direction or to the bag adsorption | suction part 110 direction.

Here, a second insertion hole (not shown) is formed at the rear side of the second moving unit 122 to be inserted through and coupled to the second screw shaft 123-2 to be rotatable. Accordingly, the second moving unit 122 screwed with the second screw shaft 123-2 by the forward and reverse rotation of the second screw shaft 123-2 causes the clamp 121 to move toward the hopper nozzle 12 or The bag is moved toward the adsorption unit 110.

Since it is substantially the same as the bag automatic transfer device which consists of a bag moving unit which receives the bag from the unit and moves the bag to the hopper nozzle for the unit packaging, the overlapping description will be omitted.

First, in the bag adsorption step (S210), the adsorption plate of the bag adsorption unit is lowered to sequentially adsorb the bags stacked in the bag automatic transfer device in units of bags.

Then, in the adsorption bag moving step (S220), the bag adsorbed by the bag adsorption part is raised to a certain height, and the bag is moved in the direction of the bag moving part.

Subsequently, in the bag taking over step S230, the clamp of the bag moving unit receives the bag moved from the bag suction unit.

Subsequently, in the adsorption position moving step of the bag adsorption unit (S240), the bag adsorption unit moves to the adsorption position for adsorbing the other bags stacked on the bag automatic transfer device after the bag is taken over to the bag moving unit.

Subsequently, in the hopper nozzle joining step S250, one side (bag inlet) of the bag of the bag taken in the bag moving unit is coupled to the hopper nozzle.

Subsequently, in the step-up position moving step of the bag moving part (S260), the bag moving part couples one side of the bag's suture part to the hopper nozzle, and then moves to the bag taking-up position absorbed from the bag suction part.

Here, by repeatedly performing the steps "S210" to "S260" to continuously supply the bags stacked in the automatic bag feeder to the hopper nozzle, it is possible to automate the bag supply process for unit packaging the stacked bags.
