Dispensing of a material into a mould
Abstract
Abstract To dispense flowable material, such as wet concrete, into an open topped mould from a reservoir having a plurality of separately controllable outlets arranged side-by-side in line, the mould and the outlets are positioned with the outlets above a datum at one end of the mould and relative movement, is caused to take place between the outlets and the mould in a horizontal direction normal to the line of the outlets. Signals are obtained continuously representing the position of the outlets from the datum and there signals are compared with signals on a prepared programme for the operation of the outlets. The outlets are opened and closed automatically to bring about flow of the material into the mould. The weight of material which has been dispensed may at all times be compared with the calculated weight which should have been dispensed and the speed of displacement between the mould and the outlets is adjusted to bring about a correct rate of delivery of the material.
