As is well known, a rotary packaging machine (not shown) is a bag feeding device that sucks a packaging bag 1 and delivers it to a pair of clamping arms 2 one by one via a bag feeding conveyor and a delivery machine. The first step of arranging the printing machine, the second step of arranging the chuck opening device, the third step of arranging the printing inspection device and the bottom inflating device, the fourth step of arranging the bag opening device, the product filling machine Consists of the fifth step of arrangement, the sixth to eighth steps of spare, the ninth step of arrangement of the sealing device, the cooling and the tenth step of arrangement of the product discharge device, and transports the packaging bags sequentially at predetermined time intervals. And get the product.

The jogo 3 is disposed in the product filling machine in the fifth step, guides the product weighed by a weighing machine (not shown), and has a cylindrical shape with a reduced diameter from the upper part to the lower part.
A ring band 5 is attached to the bottom of the jogo 3, and a ring-shaped jet pipe 10 is disposed at the lower end of the ring band 5. The ejection pipe 10 is formed with a plurality of ejection ports 11 that can be ejected outward. That is, the plurality of ejection ports 11 are provided in a direction in which they are directed toward the seal portion 1 a of the packaging bag 1.

The annular diameter of the ejection pipe 10 is a diameter that does not come into contact when the packaging bag 1 sandwiched between the sandwiching arms 2 opens through the suction tool 13 and the product drops and fills through the jaw 3. is there.
Further, the shape of the ejection pipe 10 is a circle, an ellipse, a polygon such as a square, etc., and the diameter of the ejection pipe 10 and the diameter and number of the ejection ports 11 are products that adhere to the seal portion 1a of the packaging bag 1. Select according to the nature of the powder and the flow rate of the gas to be injected (air, etc.).

The ejection pipe 10 is provided with a supply pipe 15 for supplying gas from both sides, and the supply pipe 15 is supplied with gas from a supply source (not shown) according to control of an electromagnetic valve (not shown). A dust collecting hood 20 is attached to the outer periphery of the jogo 3 via a fixture 18, and a discharge port 22 connected to a dust collector (not shown) is provided. The dust collecting hood 20 in the dust collecting hood 20 is provided. Gas is sucked from the discharge port 22.

Next, the operation of the filling jaw with the product powder removing function will be described with reference to FIG.
The dust collector (not shown) is being activated, and the gas in the dust hood 20 is being suctioned. When the packaging bag 1 having both ends sandwiched by the sandwiching arms 2 is conveyed to the filling process, the upper edge of the packaging bag 1 is opened through the suction tool 13 (FIG. 3A). The jogo 3 is lowered until the ring band 5 enters the packaging bag 1, and the product 50 weighed by the weighing machine (not shown) falls in the jogo 3 and is filled in the packaging bag 1.
