According to the present invention, a plurality of inner bags, each of which has a predetermined number of sewn needles, sewing needles, fishing hooks, and the like, which are already to be packaged, are packaged in a rustproof silver-paper wrapping paper, are stacked on a lift. At this time, for example, the thickness of the inner bag in which the sewing needle is wrapped is about 2 mm. In addition, a plurality of lifts are placed in parallel so that they can be sequentially moved to the next lift, and at the lower end of the lift there is a mechanism that sequentially raises by the thickness of the middle bag, and at the top is the lift. It is aligned with the shooter so that the inner bag falls on the shooter.

At this time, it has been confirmed that if the angle of the shooter is 40 ° or less (preferably about 30 °), the inner bag will drop under its own weight and at an appropriate speed.
The inner bag is a weighing unit for weighing the load, and the inner bag that has dropped and traveled on the shooter by its own weight is once stopped by the stopper, then comes off the stopper and weighs on the weighing platform. At this time, there is a display panel for displaying the maximum allowable weight and the minimum allowable weight on the operation panel, and these values can be arbitrarily set. The minimum allowable unit at that time is 0.2 g, which is 1
The load is equal to or less than the load per unit, and when there are more than the required number in the inner bag, or when the number in the inner bag is small, the weighing platform itself is part of the shooter due to the solenoid. The structure is such that the inside bag is removed by turning it halfway and dropped into the lower tray for storage.

Next, a vertical tray beside the shooter is stacked with a plurality of decorative packaging bags, and the bottom one is pushed out to a predetermined position of the shooter. Then, a V-shaped stamp is pressed at the fold line with the tip of the discharged packaging bag to make a fold line.

In this state, the lateral side surface of the packaging bag is mechanically fixed and moved to apply pressure, and at the same time, the packaging bag is opened by air pressure from the front of the packaging bag. Then, the inner bags that are packed in a predetermined number are stored in the packaging bag. At this time, for example, the size of the packaging bag in the case of a sewing machine needle is about 60 mm in length and about 35 mm in width, the middle bag is about 45 mm in length and 25 mm in width, and the thickness of the packing bag is about 0.1 mm. Paper is used.

When the inner bag is housed in the packaging bag and the front portion is opened, the U-shaped jig is pressed by air pressure at both ends of the front opening portion from the cut portion of the packaging bag. , The notch is open.

On the other hand, the tip of the packaging bag is bent at 90 ° by a rotating jig at the bottom of the shooter, and the protrusion of the tip of the rotating jig moves the entire rotating jig downward to move the packaging bag. The tip end portion can be inserted into the cut portion by bending the tip end portion and further by the air pressure from the front and the moving shaft by air pressure in the substantially central portion of the U-shaped jig. The packaging is completed by further pressing the fold portion (not shown).

Further, in the present apparatus, after this, by removing the stopper, the packaging bag moves on the shooter, and an optical sensor (not shown) is attached to the moving part to block the light. The completed packaging bags can be counted and displayed on the operation panel.

Then, the packaging bags that have passed through the counter are aligned in a predetermined number on the tray attached to the lower jig, and when the trays are full, the full trays are aligned by a shooter, and a new tray is placed at a predetermined position. It is an automatic machine that can.
