Abstract
An article placing assembly having a pushing mechanism constructed and arranged to engage and move articles from an article stack. The assembly has opposing pivoting gate members which cooperate to hold and release successive articles. Movable clamps further cooperate to hold the article stack as successive articles are sequentially moved from the article stack. A process is set forth for separating and removing successive articles from an article stack in a magazine.
Claims20
An article placing assembly positioned at the exit end of an article supply magazine structure having a deck for supporting a stack of articles, comprising:
- (a) a pushing mechanism constructed and arranged to engage and move successive articles from a stack of articles;
- (b) opposing pivoting gate members constructed and arranged to hold and release said articles;
- (c) opposing clip members positioned below said pivotable gate members;
- (d) at least one pair of movable clamps constructed and arranged to hold said article stack as successive articles are sequentially moved from said article stack;
- and
- (e) said exit end of said article supply magazine structure having a bottom end and opposing sides, wherein said pushing mechanism is positioned at said bottom end of said magazine exit end, and wherein said opposing pivoting gate members and said at least one pair of movable clamps are positioned at said opposing sides of said magazine exit end.
A glass placing assembly mounted at the exit end of a supply magazine structure, comprising:
- (a) a pushing mechanism constructed and arranged to engage and move an article of glass from a stack of glass articles;
- (b) opposing pivoting gate members constructed and arranged to hold and release said article of glass;
- (c) opposing clip members positioned below said pivotable gate members;
- (d) at least one pair of movable clamps constructed and arranged to hold said stack of glass articles as said articles of glass are sequentially moved from said stack of glass articles;
- and
- (e) said exit end of said supply magazine structure being defined by a bottom end and opposing sides, said pushing mechanism being positioned at said bottom end of said magazine exit end, and said opposing pivoting gate members and said at least one pair of movable clamps being positioned at said opposing sides of said magazine exit end.
A glass placing assembly mounted at the exit end of a supply magazine structure and being constructed and arranged to successively present individual glass articles for pickup by an article transfer mechanism having at least one vacuum cup, comprising:
- (a) a pushing mechanism constructed and arranged to engage and move an article of glass from a stack of glass articles, said pushing mechanism being arranged to act from below said exit end and having an upwardly facing abutment surface for engaging and supporting said successive glass articles;
- (b) opposing pivoting gate members constructed and arranged to hold and release said article of glass;
- (c) at least one pair of movable clamps constructed and arranged to hold said stack of glass articles as said articles of glass are sequentially moved from said stack of glass articles;
- (d) opposing stationary clip members positioned below said pivotable gate members;
- (e) said assembly being positioned at an angle of less than 90 degrees with respect to said at least one vacuum cup of said article transfer mechanism when in position to pickup and transfer an article of glass;
- and
- (f) said magazine structure having aligned rail members for supporting said stack of glass articles and wherein removable wear rails are mounted in said aligned rail members.
A process for releasably storing a stack of articles in a magazine assembly having an exit end being defined by a bottom end and opposing sides, comprising the steps of:
- (a) engaging the bottom of each successive article at the exit end of the magazine assembly and pushing said article upwardly to separate said article from the stack of articles;
- (b) restraining the remaining stack of articles from the opposing sides of the magazine assembly exit end;
- (c) restraining said separated article in an elevated position by the sides thereof by means of moveable side restraints positioned at the opposing sides of the magazine assembly exit end;
- and
- (d) engaging said separated article at its facing surface and removing said separated article while simultaneously removing the side restraints thereof.
