At about the same time when the folds 8, 8 are folded inward, the distance between the pair of grips g is increased to tension the support frame 1 of the extraction bag a, so that the bag mouth 7 of the filter paper bag 6 is closed.
(8) In the sealing step (h), ultrasonic vibration is applied by the ultrasonic welding device 90 while holding the central portion 2 of the support frame 1 of the extraction bag a, so that the center of the extraction bag a is The upper part of the part 2 and the bag mouth 7 of the filter paper bag 6 are simultaneously sealed.
(9) In the product discharging step (nu), the packed extraction bag a released from the grip pair g is gripped by the first clamp 110 and once delivered to the intermediate clamp 125, and received by the intermediate clamp 125. After the extracted bag a is received by the second clamp 120 and transferred above the rotary drum 130, the extraction bag a is dropped by the release operation of the second clamp 120.
(10) The extraction bag a that has fallen onto the rotating drum 130 is suspended in a manner that the left and right side edges 5, 5 are loosely fitted to the locking portions 131 of the rotating drum 130. Then, while the rotating drum 130 is intermittently rotated and stopped, the extraction bag a is in a state in which the upper end edge 1a of the support frame 1 is directed forward and in a horizontal posture, and the lower portion 6c of the filter paper bag 6 is supported by the support frame 1. It is a compact form folded up. Next, the extraction bag a is transferred onto the conveyor 145 in a state where the lower portion 6c of the filter paper bag 6 is folded over the support frame 1 by the scraping pieces 138 of the unloading means 135.
By such a series of operations of the packaging machine P, the extraction bag a filled with the coffee powder is efficiently and automatically produced.
[0047]
According to the method of packaging the material to be extracted for beverages in the extraction bag, a series of packaging processes from the supply of the extraction bag to the sealing of the filter paper bag and the discharge of the product can be completely automated, and the production capacity is high. , Excellent packaging quality can be obtained. In addition, in the case of a large extraction bag filled with materials to be extracted for multiple people, a part of the filter paper bag is folded and compacted, so individual packaging in the subsequent process of the packaging line is small. Has the advantage that it can be performed economically.
