Abstract
For saving of time and effort during replacement of soiled filter plate locked onto a seal cover of a core shooter, the filter plate is placed on a gas chamber after releasing the lock and by its lateral outward motion from the core shooter is engaged with a receptacle of a tilting plate holder. A subsequent retraction of the gas chamber without the filter plate into the core shooter clears the path for tilting of the plate holder and with it positioning of a second receptacle carrying a cleaned filter plate into the vacant position. A renewed to-and-fro motion of the gas chamber serves the acceptance of the cleaned filter plate and its retraction to the seal cover of the core shooter, in order to lock the plate to the cover.
Claims8
A core shooter apparatus comprising:
- (a) a core box,
- (b) a core shooting chamber,
- (c) a gas chamber having a top on which a filter plate can rest, wherein the core shooting chamber and the gas chamber are movable transversely along a path between a first position with the gas chamber disposed above the core box and the core shooting chamber spaced laterally from the core box, and a second position with the gas chamber spaced laterally from the core box and the core shooting chamber disposed above the core box;
- (d) a seal cover, the seal cover being movable between (i) a sealed position wherein the seal cover contacts either a top of the gas chamber with the gas chamber and core shooting chamber in the first position or a top of the core shooting chamber with the gas chamber and core shooting chamber in the second position, and (ii) an open position wherein the seal cover is spaced from either the top of the gas chamber with the gas chamber and the core shooting chamber in the first position or the top of the core shooting chamber with the gas chamber and the core shooting chamber in the second position;
- the seal cover comprising a lower end to which a filter plate can be attached and detached such that a filter plate detached from the lower end of the seal cover with the gas chamber in the first position can rest atop the gas chamber;
- and
- (e) a tilting holder comprising a plurality of filter plate receptacles, including a first filter plate receptacle and a second filter plate receptacle, the tilting holder being disposed along the path to which the gas chamber is movable and being pivotable about a pivot axis such that (i) the first filter plate receptacle can be pivoted to a position in the path wherein, when a filter plate rests atop the gas chamber and the gas chamber is moved transversely from the first position to the second position, the transverse motion of the gas chamber can cause the filter plate resting atop the gas chamber to engage with the first filter plate receptacle and to be transferred to the tilting holder;
- and (ii) the second filter plate receptacle can be pivoted to the position in the path wherein, when the second filter plate receptacle carries a clean filter plate and the gas chamber moves to the second position and presses against the second filter plate receptacle, the clean filter plate is released from the second filter plate receptacle to a position resting atop the gas chamber.
