Next, a description will be given of the operation. The limit switch 24a stops the limiter 24a at a position where the coupler 20a of the roller chain attached to the coupling frame 20 is started, and the bag is attached to a bag opening holding device (not shown). The center of the bag opening holding device of the automatic weighing and filling machine A is stopped by the limit switch 23 at a position where the center of the bag placed on the support stand coincides with the center of the bag placed on the support stand. The supporter moves up and down, but does not vibrate, and the pusher also moves up and down so that the open bag is filled with tea from the automatic weighing and filling machine A at a predetermined position. In accordance with this bag, the press fitting and the support base are adjusted to the height of the bag opening holding device of the automatic weighing and filling machine A. For example, when the bag is the smallest, the two cylinders 5 and 6 provided with different strokes provided between the guide rods 4 and 4 are connected with each other by the piston rods, so that the cylinders 5 and 6 are operated together. When the piston rods of the cylinders 5 and 6 are fully extended, the support 14 of the bag is set at the highest position a. In the case of a normal bag for packing, only one cylinder is operated to the position b. When the bag is set, if the bag is large, the setting position of the bag support base 14 can be set to a desired position such as the position c without operating both cylinders. There is no need for adjustment, and anyone can simply operate the switches and the like. The adjustment of each of the cylinders 5 and 6 may be a stepless adjustment. Then, the tea is filled into the bag from the automatic weighing and filling machine A while vibrating the pedestal of the bag. Since the bag is filled while being vibrated in this way, it is most suitable for filling bulky articles, Operation that does not require adjustment of the position of the bag opening holding device can be performed. After filling, if the filling is set at a high position, the cylinders 5 and 6 must be returned to their original positions, and then the slides and rollers (not shown) will be used to move the clamp from the support base to automatically weigh bags. The transfer operation is performed from the position of the filling machine A to the center of the fine adjustment filling port. At this time, the filled bag is transported by the press fitting without being deformed. When one step is completed, the motor 16 is rotated backward to return the roller chain coupler to the start position, and the same operation can be repeated. Since the pusher follows the adjustment of the pedestal of the bag up and down, the portion that swells when the bag is filled is always shaped.
