Device for inserting partition lattice in carton

An apparatus for inserting into a hollow carton a partition lattice which is assembled from longitudinal partition panels having slits at equal spaces extending upward from the lower edges thereof and transverse partition panels having slits at equal spaces extending downward from the upper edges thereof, whereby inserting said slits into one another forms a lattice-like shape, said apparatus comprising:

• a support table;
• feeder means toward the front of said table for feeding the folded partition lattices overlapping one on the other in a vertical arrangement on the table towards the front end of said table;
• opening means for opening the folded partition lattice, said opening means comprising:
• a plate member in front of the leading partition lattice, said plate member being parallel to the longitudinal partition panel at one side thereof and movable therefrom while maintaining the parallel relation in respect to the partition lattice;
• pivoted arms, equal to the number of partition panels, pivoted on said plate member at an angle of 45.degree. before the panel is moved with the same intervals therebetween as between said transverse partition panels;
• suction discs provided on the ends of said arms sucking the end portions of said transverse partition panels;
• and
• a turnable plate adapted to cause said arms to turn synchronously 90.degree. when said plate member moves away from said partition lattice;
• lifting means at the front of said opening device for lifting the opened partition lattice as said lifting means elevates;
• transfer means for transferring the lifted partition lattice to a position directly above a waiting hollow carton;
• and
• means for inserting the partition lattice into said carton and for releasing the partition lattice from being held by said transfer means.
