Abstract
A high speed linear bagging machine and method of bagging a product with such machine is described. The machine has a reciprocating linear bagger assembly which has a straight drive member with a carriage connected thereto. A drive having a pair of coils is used to drive the straight drive member to displace the carriage. A stroke controller is used to control the coils dependent on a desired forward and rearward displacement stroke of a carriage along the drive member. A product receptacle is secured to the carriage and displaceable to a bagging station. A bag engaging member is connected to the carriage and a product arresting member is displaceable for abutting relationship with an end of a product at the bagging station. The bag engaging means engages an open end of a bag at a forward end of the displacement stroke adjacent the bagging station and withdrawing the open end of the bag over the product which is maintained substantially stationary by the product arresting means during a reverse stroke of a carriage whereby to insert the product in the bag and discharge the bagged product. The drive member is comprised of a straight thrust rod of magnetic material which constitutes a stator of the linear motor. The pair of coils are connected to the carriage and energized for displacing the carriage along the thrust rod to cause displacement of the carriage.
