A bulk bag filler for filling bulk bags having bag hanging loops and a fill spout is provided. The filler includes a bag filling head having at least a moveable portion that can be moved from a filling position, in which the hanging loops are suspended from hanging loop supports in a position to allow the bulk bag to be filled, to a bag attaching position, in which at least some of the hanging loop supports for attachment of a bulk bag to be filled and a bag spout connection are positioned in proximity to a side of the bag filler. A method for loading a bulk bag is also provided.

What is claimed is: 1. A bulk bag filler for filling bulk bags having bag hanging loops and a fill spout, the filler comprising: a bag filling head including a base portion and a moveable portion that is moveable from a bag filling position, in which the hanging loops are suspended from hanging loop supports located in a generally horizontal plane to allow the bulk bag to be suspended in a generally upright vertical position for filling, to a bag attaching position, in which the hanging loop supports are located in a second plane angled from the first plane for attachment of a bulk bag. 2. The bulk bag filler of claim 1, wherein the bag filling head is mounted to at least one support carriage for up and down movement. 3. The bulk bag filler of claim 2, further comprising an actuator for up and down movement of the bag filling head. 4. The bulk bag filler of claim 3, wherein the actuator is a powered lilting device. 5. The bulk bag filler of claim 2, further comprising a frame with two vertically extending posts, the at least one support carriage comprises two support carriages, one of the support carriages being connected to each of the posts for up and down movement of the bag filling head. 6. The bulk bag filler of claim 1, wherein the moveable portion of the bulk bag filling head is mounted for pivoting movement about a generally horizontal axis on the base portion of the bag filling head. 7. The bulk bag filler of claim 1, wherein the moveable portion is pivotable to a position in proximity to a front side of the bag filler. 8. The bulk bag filler of claim 1, further comprising an actuator mounted between the moveable portion and the base portion of the bag filling head for movement of the moveable portion of the bag filling head between bag filling position and bag attaching position. 9. The bulk bag filler of claim 1, further comprising a bulk material fill tube connection located on an upper part of bag filling head. 10. The bulk bag filler of claim 9, further comprising a sealed connector assembly for the bag fill spout located on the moveable portion of the bag filling head, and a gasket located on the base portion of the bag filling head to provide a sealed connection between the bulk material fill tube and the sealed connector assembly when the moveable portion is in the bag filling position. 11. The bulk bag filler of claim 10, further comprising a control for the sealed connector assembly located on the moveable portion of the bag filling head. 12. The bulk bag filler of claim 1, further comprising at least one tilt release actuator located on the bag filling head to unlock the moveable portion of the bag filling head for movement to the bag attaching position. 13. The bulk bag filler of claim 1, further comprising a controller to control movement of the moveable portion of bag filling head and for controlling up and down movement of the bag filling head. 14. The bulk bag filler of claim 1, wherein the moveable portion comprises a bag hanging frame on which the hanging loop supports and respective latch mechanisms are mounted. 15. The bulk bag filler of claim 14, wherein the bag hanging frame is pivotable from the bag filling head about at least one pivot axis located along a side of the bulk bag filler. 16. A bulk bag filler for filling bulk bags having bag hanging loops and a fill spout, the filler comprising: a bag filling head including a base portion and a moveable portion that is moveable from a bag filling position, in which the hanging loops are suspended from hanging loop supports in a position to allow the bulk bag to be filled, to a bag attaching position, in which at least some of the hanging loop supports for attachment of a bulk bag to be filled and a bag spout connection are positioned in proximity to a side of the bag filler. wherein the hanging loop supports have at least one associated latching mechanism comprising: a support member, pivotally mounted to a latch frame at a first pivot position, and having a first bag loop support contacting surface at a first end thereof and, at a second end thereof, contact a first end of a latch member that is pivotably mounted at a second pivot position, a latch pin connected to an actuator which is moveable from a first position, in which it extends under a second end of the latch member, to a second position, away from the latch member, upon the latch pin being moved to the second position, the first end of the support member being pivotable downwardly to release the bag loop support, and upon the bag loop support no longer contacting the support member, the support member being weighted so that the first end pivots upwardly to a reset position upon the latching mechanism being re-oriented to the bag attaching position in which the first end of the support member is in a bag loop support engaging position, so that the bag loop support can be pivoted into a re-latched position by causing the support member to pivot out of the way as the support arm is reset, and the support member is biased by gravity so that the first end returns to the re-latched position after the bag loop support is in the re-latched position. 17. A method of loading a bulk bag having hanging loops and a fill spout, comprising: providing a bulk bag filler having a bag filling head with a base portion and at least a moveable portion with a bag fill spout connection, the movable portion being movable from a bag filling position, in which the hanging loops are suspended from hanging loop supports located in a generally horizontal plane to allow the bulk bag to be suspended in a generally upright vertical position for filling, to a bag attaching position, in which the hanging loop supports are located in a second plane angled from the first plane for attachment of a bulk bag; moving the moveable portion of the bag filling head to the bag attaching position; attaching the bag hanging loops to the hanging loop supports located in the second plane; attaching the bag fill spout to the bag fill spout connection; moving the moveable portion of the bag filling head to the filling position; and discharging material into the bulk bag through the bag fill spout. 18. The method of claim 17, further comprising: adjusting a height of the bag filling head to a desired position based on a size of the bulk bag being filled. 19. The method of claim 17, further comprising: adjusting a height of the bag filling head to a desired position for attaching the bag hanging loops and the bag spout. 20. The method of claim 17, wherein the moving of the moveable portion of the bag filling head to the bag attaching position further comprises tilting the moveable portion of the bag filling head to a position in which the hanging loop supports are located in the second plane which is angled within thirty-five (35) degrees of vertical. 21. The bulk bag filler of claim 1, wherein the second plane is angled from the first plane by at least approximately fifty-five (55) degrees, whereby the second plane is located within approximately thirty-five (35) degrees of true vertical.
