ABSTRACT:
An arrangement for sorting of refuse or laundry into various kinds of goods, comprising a transportation system in which the refuse or laundry is transported in conveyance shafts from a number of depositing places to a common collecting place with separate containers for the various kinds of goods to be collected. Each depositing place comprises a number of storage spaces, one for each kind of goods to be collected and access to these storage spaces is gained through chute doors. The storage spaces are opening in a substantially vertical dumping shaft and each discharge opening is provided with a hatch which can be kept in closed position by means of a locking mechanism. As long as the hatch is closed each storage space will collect the refuse or laundry put into the space through the opening covered by the chute door. When the locking mechanism is disengaged the hatch opens under the influence of the weight of the goods and falls down through the dumping shaft into a substantially horizontal conveyance duct in which the refuse is pneumatically transported to the collecting place with the containers for the different kinds of goods. Alternatively the vertical dumping shaft bifurcates in ducts debouching into the different containers in which the refuse or laundry will fall by gravity. In both cases, however, switching valves are located in the conveyance shaft for distributing the various kinds of goods to be collected to the corresponding containers. The switching valves are operated by a control mechanism also cooperating with the hatch locking mechanisms so that storage spaces for one and the same kind of goods are connected to their corresponding containers.
