Abstract
A suction conveyor or delivery arrangement for the gravimetric allocation of pourable material components to several demand stations has a storage container containing in each case one component connected by, in each case, one delivery line to a distributor and a separator at each demand station, which is connected via a delivery line to the distributor, a suction line with stop valve to a suction fan and can be emptied via a closable discharge opening at the demand station. A control for the demand-dependent dosing of the components has a demand indicator, which releases a control signal for setting the distributor to the desired component and for opening the stop valve, as well as a setting device which, on reaching a predetermined quantity, releases a control signal for opening a ventilating valve in the delivery line and for closing the stop valve. Each separator has two chambers, whereof the lower chamber has the closable discharge opening, while the upper chamber has connections for the delivery line, the suction line and below the same a weighing container receiving the separated material and supported by a transducer and which has a material outlet and a closure, which is c…
