Abstract

926,997. Foundry plant. BADISCHE MASCHINENFABRIK A.G. April 13, 1960 [Feb. 5, 1960], No. 13156/60. Class 83 (1). In a mechanised foundry there is allocated to each group of bottom box moulding machines 2 and upper box moulding machines 3 a substitute moulding machine 9 or 10 respectively, and on the empty box side of the conveyer system 1 an empty box stacking appliance 11 or 12 corresponding to each substitute moulding machine and located between it and the moulding machine it is to be changed for. Each stacking appliance is controlled so that on the change taking place due to a change of pattern being necessary e.g. machine 9 replacing machine 2A, it takes up the empty boxes e.g. A1-A6, Fig. 2, becoming superfluous from the rail system, or, e.g. when machine 2A replaces machine 9, deposit the empty boxes as they become necessary, on to the rail system so that an uninterrupted flow of moulds is secured. Unless machines 2A and 2B are to be replaced at the same time one substitute machine 9 and stacking device 11 are sufficient provided that they are movable to maintain their appropriate distances from the machine to be replaced. There may be more than two simultaneously operating machines in each group of machines for upper and lower moulding boxes. The change-over may be effected by the use of a counter mechanism at each moulding machine to count the required number of moulds before a pattern change is required, the counter then setting in motion the stacking appliance and the substitute moulding machine. The mould weights are placed on the moulds at 4, 5 is the casting track, 6 the cooling section, 7 the emptying appliance and 8 a device for cleaning the conveyer plates.
