Abstract
A scrap removal apparatus (35) for retrieving scrap material (32,33) from a two-piece table (19) includes a programmed lift arm assembly (37) movable between the table (19) and scrap accumulating areas (82,83) and has remotely actuable mechanical gripping devices (45) for positively clamping onto the scrap material (32,33). One form of gripping device is a clamp (50) having a finger (57) and an enlarged pad (54), the fingers (57) of the respective clamps (50) movable through slots (70) defined in the outer table edge (21) to grip the overlying outer scrap (32). Another form of gripping device includes a blade (80) for pinning the inner scrap (33) against a stop (73) near the table center.
Claims9
In a device having a table (19) upon which scrap (32,33) to be removed lies, a scrap removal apparatus (35) comprising:
- a lift arm assembly (37);
- means (36) for supporting said lift arm assembly (37) and elevating and moving said lift arm assembly (37) between a first position adjacent and above the table (19) and at least one other position away from the table (19) where said scrap (32,33) may be deposited;
- a plurality of clamps (50) carried by said lift arm assembly (37) adapted to grip a portion of the scrap (32), a table (19) having slots (70) defined at the edges thereof which the scrap (32) overlies and through which the clamps (50) are partially movable;
- remotely actuable power means (60) for closing and opening said clamps (50) for gripping and releasing said scrap (32);
- a blade (80) and a stop (73) are carried by said lift arm assembly (37);
- and
- a remotely actuable power means (75) is provided for moving said blade (80) toward and away from said stop (73), said blade (80) being moved toward said stop (73) to gather another portion of the scrap (33) and to hold said scrap (33) against said stop (73).
In a device having a table (19) with separate inner and outer portions (22,21) on which material (27) is placed and is cut leaving an inner piece of scrap (33) on the inner table portion (22) and a separate outer piece of scrap (32) on the outer table portion (21), a scrap removal apparatus (35) comprising:
- a lift arm assembly (37);
- means (36) for supporting said lift arm assembly (37) and moving said lift arm assembly (37) between a first positon adjacent and above the table (19) and at least one other position away from the table (19);
- a plurality of clamps (50) carried by said lift arm assembly (37) adapted to grip a portion of the outer scrap (32), the outer table portion (21) having slots (70) defined at the edges thereof over which the outer scrap (32) lies and through which slots (70) the clamps (50) are partially movable;
- remotely actuable power means (60) for opening and closing said clamps (50);
- a blade (80) and a stop (73) carried by said lift arm assembly (37);
- and
- remotely actuable power means (75) for moving said blade (80) toward said stop (73) along the inner table portion (22) so that said blade (80) gathers the inner scrap (33) and holds it against said stop (73).
