Abstract: In a device for collecting and re-cycling articles sent toward feeding channels, a selecting member is situated downstream of a station where the articles are accumulated, for receiving, in a predetermined way, the articles from the accumulation station. The selecting member selects and holds complying articles, separating them from fragments and from powders associated thereto. A linear conveyor member, situated downstream of the selecting member, receives the complying articles and sends them in ordered way to inlets of the feeding channels. Collecting means are situated downstream of the inlets for receiving, from the linear conveyor member, the exceeding articles situated near the inlets. Transferring means receive, from the collecting means, the exceeding articles and transfer them to an initial section of the selecting member, so that the articles are collected, recycled and their compliance is verified again.

Abstract: Large items such as magazines or large envelopes lie flat upon and are transported by a first conveyor in a first, transverse direction until they sequentially encounter a frustoconical member rotatably mounted to a back wall. A second conveyor is disposed normal to the first conveyor so that it transports the items that have encountered the frustoconical member in a second direction normal to the first. A rotatably mounted barrier has a first, retracted position where it does not interfere with items approaching the frustoconical member and a second, deployed position where it stops the items short of the frustoconical member. The position of the barrier is controlled by information concerning postal routes. The items are sorted into sharply defined groups that are transversely staggered with respect to one another.

Abstract: A sieving device having a mesh screen detachable from a frame body is capable of easily removing particulate material remained on the mesh screen and cleaning of the mesh screen and being installed even in a confined space requiring a sanitary condition. The particulate material sieved through the mesh screen is prevented from getting out of a collecting container or scattering around. With a vibration generating means in the sieving device, sieving vibration can be efficiently produced with a relatively small power with preventing coagulation and agglomeration of the particulate material. By corrugating the bottom of the mesh screen, the efficiency of sieving the particulate material be increased remarkably.

Abstract: Aggregate mixtures such as dirt, sand, rock, concrete, etc. are separated into piles according to size by continuous agitation of the mixture and by gravitational and centrifugal forces exerted thereon. A container for the material, such as the bucket of a backhoe, has the bottom thereof at least partially open. An adjustable, hydraulically-driven rotating disk attaches to and covers the open portion of the bottom of the container, the combination having a gap, or a selected spaced-apart relationship, between the stationary container and the rotating disk. The mixture is agitated by the rotating disk and by contact with the other particles in the container. Particles smaller than the selected gap distance are thrown out through the gap between the disk and the open portion of the container by centrifugal force. Material larger than the selected gap size remains in the container.

Abstract: A batching of currently supplied articles with non-uniform weights into portions of a uniform target weight is effected by passing the articles through a weighing station (6, 8) to a distribution system (12), in which the articles (4) are selectively allocated to a plurality of receiver bins (14). It is known to improve the capacity of such a system by way of probability calculations based on the normal distribution of the articles in the supply flow, but according to the invention it is still better to base such calculations on a regularly updated recorded histogram (28) of the weight distribution of a relatively high number of newly weighed articles. Thereby the target calculations will rely on factual rather than just expected conditions, and a very important result is that it is possible to effect relevant batching even when the article weights in the supply flow are not normally distributed.
