In a station of a boxing machine, for withdrawing and erecting flat folded tubular blanks into boxes, a blank withdrawing rocker arm strips out a flat folded blank from a magazine and places it onto a operating member situated below and associated to an auxiliary conveying line. The auxiliary conveying line extends along a close loop path. Gripping suction cups associated to the operating member engage the lower side of the blank. An erecting arm with a shaped flap makes edge-resting sides of the blank rotate synchronously, about respective articulation lines adjoining to a lower side, until a corresponding box is erected. A shaped guide engages with the carriage and moves the box laterally with respect to the auxiliary conveying line, to insert the box into a corresponding seat on a box conveying line situated beside the auxiliary conveying line.

What is claimed is: 1. In a boxing machine including: a magazine for flat folded box blanks, disposed in a pile, to be erected into corresponding boxes; a station for withdrawing and erecting said flat folded tubular blanks into boxes; a box conveying line extending beside said station for conveying erected boxes obtained from said folded box blanks and introduced, by a transversal movement, into seats made on said box conveying line; an article conveying line situated beside said box conveying line on a side opposite to said station; pushing means situated downstream of said station for transferring said article from the article conveying line into said boxes conveyed along said box conveying line; said station for withdrawing and erecting said flat folded tubular blanks includes: an auxiliary conveying line, that extends along a close loop path below said box conveying line and near to said magazine; withdrawing means for withdrawing said flat folded blank from bottom of said pile contained in said magazine and for placing withdrawn flat folded blanks onto said auxiliary conveying line; operating member associated to said auxiliary conveying line for receiving said blanks being erected into boxes; gripping suction cups associated to each operating member of said operating members, for engaging a lower side of one blank held by said withdrawing means; controlled erecting means situated in each operating member of said operating members for making edge-resting sides of a relevant blank rotate synchronously, about respective articulation lines adjoining said lower side, until a quadrilateral box is defined; transferring means situated in each operating member of said operating members for moving said box laterally with respect to said auxiliary conveying line for inserting said box into a corresponding seat on said box conveying line. 2. A station, according to claim 1, including: sliding blocks guided along paths formed along the close loop path of the auxiliary conveying line; a series of guiding stems fastened, on both sides, to said sliding blocks; a series of carriages, which slide, crosswise to said auxiliary conveying line, on respective guiding stems; a bracket, removably fastened to each carriage of said carriages; gripping suction cups carried by said bracket. 3. A station, according. to claim 2, wherein said transferring means act on the carriage of each of said operating members to determine transversal positioning of said operating member during passage of the work run of said auxiliary line, said transferring means including a shaped guide, situated below said carriage, and engaging with devices made in said carriage. 4. A station, according to claim 1, wherein said controlled erecting means act on one edge-resting side situated downstream of said lower side of the blank, with respect to a forward direction of said auxiliary conveying line, with said controlled erecting means including; an arm pivoted to a pivot point of a plate of said operating member; a shaped flap, fastened to said arm an idle roller mounted to said arm and following a profile of a linear cam extending in the work run of the auxiliary line, so as to determine the arrangement of the arm and of the shaped flap. 5. A station, according to claim 4, wherein said plate is made integral with a sliding block situated on a side of said auxiliary conveying line situate alongside said box conveying line. 6. A station, according to claim 4, wherein said shaped flap has such dimension as to strike said edge-resting box side near the articulation line, joining said edge-resting box side to said lower box side. 7. A station, according to claim 4, wherein oscillation range for said arm is limited by abutment means including a pin fastened to the plate and engaged with a slot made in the arm. 8. A station, according to claim 1, wherein said withdrawing means include a rocker arm.
