ABSTRACT:

TECHNICAL FIELD
Apparatus for filling a bag and transferring the filled bag to a bag tying apparatus is disclosed.
BACKGROUND OF INVENTION
For filling and tying bags of certain products, such as tortillas, the bags are generally filled manually and moved by a worker to a bag closing apparatus. Tortillas and similar items are generally stacked one on top of the other to form a generally cylindrical stack of a predetermined number of tortillas. The stack is then deposited in a bag and the bag closed for shipment.
Further, filling bags with granular material or several small items generally requires that the bag be held in an upright position while it is being filled and transported until the open neck of the bag has been closed.
A need exists for a bagger that can open and hold a bag while it is being filled and associated apparatus for removing the filled bag from the bagger, closing the bag and depositing the closed bag on a suitable conveyor to be deposited in boxes or other containers for shipment
SUMMARY OF INVENTION
Bagging apparatus, bag transfer apparatus and a tyer are mounted on a common frame An air jet is delivered into a bag supported by one edge on a wicket. After air has been delivered to open the bag, a pair of horns rotate about horizontal axes to move into and engage the upper end of the bag. A pressure switch is positioned to indicate whether or not the horns have properly engaged the upper end of the bag for filling. After the bag has been filled, a bag transfer mechanism moves to a position adjacent the horns for gripping the neck of the bag for removal from the bagger and for transporting the bag to a bag tying mechanism. The bag tying mechanism wraps a twist-tie around the neck of the bag and deposits the closed bag on a conveyor.
