Abstract
This invention relates to an apparatus suitable for conveying shaped blanks. This apparatus includes a pair of screw shafts extending in a direction of conveying the blank. Members for holding attracters threadably coupled to these screw shafts are movable along guide shafts. Respectively provided at the ends of the guide shafts on one side are connecting members. Screw shafts threadably coupled to these connecting members drives the attracter holding members to approach or separate from each other on a line connecting the two guide shafts. Pinions provided near the opposite ends of the guide shafts rotatably move on racks, whereby the attracter holding members are synchronously moved in parallel to each other.
Claims8
A blank conveying apparatus comprising:
- a frame;
- a movable member supported by said frame and provided in a manner to be freely reciprocated with a predetermined pitch of a conveying stroke in a direction parallel to the direction of conveying said blank;
- a vertically movable member which is supported by said movable member in a manner to be movable in the vertical direction;
- driving means for reciprocating said movable member;
- a plurality of screw shafts provided on said vertically movable member in parallel to one another in a direction of moving of said movable member;
- a plurality of attracter holding members threadably coupled to said screw shafts at every pitches of the conveying stroke and each having an attracter;
- a plurality of guide shafts disposed in parallel to said screw shafts, for supporting said plurality of attracter holding members in a manner to be movable in the axial direction of said screw shafts and unrotatable;
- widthwise adjusting means for moving said guide shafts and said screw shafts, which are opposed to each other, respectively, in parallel to a plane of conveying said blank and in a direction perpendicular to the axial lines of said guide shafts and said screw shafts, independently of other guide shafts and screw shafts;
- and
- equalizer means for synchronizing the movements of opposite ends of said guide shafts.
