Abstract
Automated method and machinery for fabricating a wrought-iron fence panel. The machinery includes (a) automated programmable machinery for welding vertical pickets to horizontal runners to form a fence panel; (b) automated programmable machinery for straightening the fence panel; (c) automated programmable machinery for washing the fence panel; (d) automated programmable machinery for drying the fence panel; (e) automated programmable machinery for painting the fence panel; and (f) automated programmable conveyor machinery for conveying the vertical pickets, the horizontal runners, and the fence panel from station to station.
Claims26
An automated method for fabricating components of a wrought-iron fence, the method comprising the steps of:
- (a) providing a plurality of horizontal runners and a plurality of vertical pickets;
- (b) automatedly welding the vertical pickets to the horizontal runners to form a fence panel;
- (c) automatedly transferring the fence panel to a table run-out conveyor which includes a set of chains with a pickup block on each chain;
- (d) utilizing the table run-out conveyor to automatedly transfer the fence panel to a conveyor loading station which includes a hydraulic-driven unit with pickup hooks capable of conveying the fence panel;
- (e) utilizing the hydraulic-driven unit to automatedly transfer the fence panel to an overhead conveyor line;
- (f) utilizing the overhead conveyor line to automatedly transfer the fence panel to a fence section straightener;
- (g) utilizing the fence section straightener to automatedly straighten the fence panel;
- (h) utilizing the overhead conveyor line to automatedly transfer the straightened fence panel to a wash tank;
- (i) utilizing the wash tank to automatedly wash the fence panel;
- (j) utilizing the overhead conveyor line to automatedly transfer the washed fence panel to a drying station;
- (k) utilizing the drying station to automatedly dry the washed fence panel;
- (l) utilizing the overhead conveyor line to automatedly transfer the dried fence panel to a paint tank;
- and
- (m) utilizing the paint tank to automatedly paint the fence panel.
Automated machinery for fabricating components of a wrought-iron fence from a plurality of horizontal runners and vertical pickets, the machinery comprising:
- (a) automated programmable means for welding the vertical pickets to the horizontal runners to form a fence panel;
- (b) automated programmable means for straightening the fence panel;
- (c) automated programmable means for washing the fence panel;
- (d) automated programmable means for drying the fence panel;
- (e) automated programmable means for painting the fence panel;
- (f) automated programmable conveyor means for conveying the fence panel from the welding means to the fence-straightening means;
- (g) automated programmable conveyor means for conveying the fence panel from the fence-straightening means to the washing means;
- (h) automated programmable conveyor means for conveying the fence panel from the washing means to the drying means;
- and
- (i) automated programmable conveyor means for conveying the fence panel from the drying means to the painting means.
