Abstract: A packaging device includes a first sealing device which performs a first sealing process based on an impulse seal method on a bag in a chamber being in a vacuum state. A second sealing device performs a second sealing process based on a heat plate sealing method on a planned seal portion of the bag. A cooling device cools the bag. A discharge unit receives, in the release position, the bag released from the transfer mechanism after the cooling process. The transfer mechanism linearly transfers the bag in a direction along a surface of the bag from the delivery position to the release position.

Abstract: An empty bag supply method and apparatus first lifting up with a first suction member an empty bag of which bag bottom being in contact with and positioned by a first positioning stopper. The lifted bag is then held by chucks and transported upwards so that the empty bag is vertical with the bag bottom facing upward, and then a second suction member suctions the empty bag near the bag mouth and transports it onto a conveyor with the bag mouth facing forward, so that the bag mouth of the bag is stopped and positioned by a second positioning stopper. The empty bag is then lifted up by a third suction member, held by a chuck and transported upward so that the attitude of the bag is changed to vertical with the bag mouth facing upward, and then the bag is transferred to a gripper of a packaging apparatus.

Abstract: A first control signal generating unit and a second control signal generating unit output a first control signal and a second control signal when magnitude of an impact corresponding to first and second sensor signals are greater than a first and second threshold. A third control signal generating unit outputs a third control signal when detecting disruption of the second sensor signal. An activating signal generating unit activates a protecting device when the first control signal is output, and when one of the second control signal and the third control signal is output. A fourth control signal generating unit outputs a fourth control signal when detecting an abnormality other than disruption of the second sensor signal. The third control signal generating unit restricts outputting the third control signal when the fourth control signal is output.

Abstract: An apparatus and method for producing extruded elongate pasta of substantially even lengths. The apparatus includes: an extruder; a first cutter for cutting uneven tip portions of the bunches of elongate pasta; a second cutter for cutting the bunches of the elongate pasta, whose uneven tip portions have been cut, into an even length; and a sorting part for selectively sorting the bunches of elongate pasta having been cut into the even length with the second cutter from the uneven tip portions having been cut with the first cutter.
