The operation of 1 is automatically canceled.

When the adsorber 10a of the sucker 10 is adsorbing the liquid pouring port 2 and the suction of the adsorber is poor and the negative pressure does not rise, the sucker 10a is sucked after a certain period of time. Is forcibly returned to the initial position so that the intermittent movement of the conveyor 6 is not hindered.

On the other hand, in the spout welding process, the paper container 1 conveyed by a spout detection sensor (not shown).
When it is detected that the liquid pouring port 2 is not temporarily attached to the end of the driven arm 44 via the bridge member 49, the photoelectric switch operates to extend the pressurizing operation canceling air cylinder 50. By pushing up the portion against the spring 45, the engagement between the roller 44a of the driven arm 44 and the plate cam 37 is released, and the vibration horn 22c of the ultrasonic welder 22 is not pressed. It is like this.

In the above embodiment, the sucker-1
The suction of the liquid spout 2 by 0 and the forward and backward driving of the sucker 10 were both performed by the sucker suction / insertion air cylinder 11, but the suction of the liquid spout 2 by the sucker 10 was provided with a separate pipe or the like. It is also possible to suck.
