Abstract
A machine for packaging loaves in bags having a reciprocating bag magazine in which the at any time topmost bag is ready for receiving a loaf. Each loaf is pushed into a bag with such speed that when hitting the bag bottom the loaf will take the bag along away from the magazine. After having left the magazine the bagged loaf slides onto a discharge conveyor. Limit switches control the moment of bagging the following loaf.
Claims8
A machine for packaging box-shaped articles such as loaves of bread in bags, said machine including a bag magazine containing a stack of bags, article feed means including pusher means mounted for reciprocation between a retracted position and an extended position for feeding the articles toward the bag magazine, spaced guide finger means for guiding the articles and bags relative to each other during insertion of an article into the bag, a discharge conveyor for removing the bagged articles, means for reciprocating said bag magazine between a first position spaced from the guide finger means and a second position adjacent the guide finger means in which the guide finger means partially overlie the magazine, means for inflating the topmost bag in said magazine when said magazine is in said first position so that movement of said magazine to said second position causes the uppermost inflated bag of said magazine to receive the ends of said guide finger means on its interior, said feed means including power means for operating said pusher for feeding one article at a time into the uppermost inflated bag by moving the article through the space between said spaced guide finger means into the uppermost bag when the bag magazine is in its second position following arrival of the next previously bagged article at said discharge conveyor and wherein said power means for operating said pusher means operates the pusher at a speed to move the article at a sufficient speed to cause forceful engagement of the article with the bottom of the bag to move the bag from the top of the bag magazine to the discharge conveyor.
