An apparatus for supplying spout attachment bags including a first transfer device for transferring a spout attachment bag in a horizontal orientation, a positioning device for receiving and horizontally positioning the spout attachment bag transferred from the first transfer device, a second transfer device for transferring upward the spout attachment bag positioned by the positioning device and changing the spout attachment bag from the horizontal orientation to a vertical orientation so that the spout attachment opening faces upward and is horizontal, and a detection device. The position of the spout attachment opening on the positioning device is detected by the detection device and is compared to a preset reference position, so that any amount of deviation between the two positions is corrected, thus keeping the height positions of the spout attachment openings of the spout attachment bags changed to a vertical orientation steady. |

1. An apparatus for supplying spout attachment bags for supplying a spout attachment apparatus with spout attachment bags each having a spout attachment opening in one corner thereof, said apparatus comprising:
a positioning device for positioning a spout attachment bag at a specific position in a horizontal orientation in which a spout attachment opening of the spout attachment bag faces forward, a first transfer device for transferring the spout attachment bag, which is in a horizontal orientation and in which a spout attachment opening thereof is facing forward, to said positioning device, and a second transfer device for transferring upward the spout attachment bag positioned by said positioning device and, in a course of said transfer, changing the spout attachment bag from a horizontal orientation to a vertical orientation in which the spout attachment opening faces upward and is horizontal, wherein said positioning device is comprised of:
a conveyor on which a supplied spout attachment bag is placed and which sends said bag forward, anda side edge stopper and a top edge stopper which are contacted by one side edge and a top edge flanking the spout attachment opening of the spout attachment bag,one vertical plane being set as a positioning reference plane, andsaid side edge stopper and said top edge stopper being disposed so that a perpendicular line passing through a center of the spout attachment opening of the spout attachment bag is located in said reference plane when the spout attachment bag has come into contact with said stoppers, said second transfer device is comprised of:
an arm fixed to a rotary shaft which is provided horizontally,a driving source for rotating said rotary shaft and reciprocally swings said arm, anda suction member which is provided at a distal end of said arm and is moved within a plane parallel to said reference plane when said arm is swung, andwhen said arm is swung downward, said suction member picks up the spout attachment bag, andwhen said arm is swung upward, the spout attachment bag picked up by said suction member is raised and changed from a horizontal orientation to a vertical orientation; and said apparatus for supplying spout attachment bags is further comprised of:
a detection device for sensing a position of the spout attachment opening of said bag positioned by said positioning device, anda control device for comparing a position of the spout attachment opening sensed by said detection device to a preset reference position, and for controlling operation of said driving source based on an amount of deviation between said two positions, said control device controlling the operation of said driving source to correct a position of a swing end of said arm that is swung upward, thus keeping steady a height position of the spout attachment opening of the spout attachment bag that is in a vertical orientation. |
