Abstract: An apparatus for separating metal particles from a material stream of a bulk material, comprising a detection device for detecting metal particles in the material stream and a separating device configured to separate a portion of the material stream in which the metal particles are contained, the separating device comprising a housing having a material inlet, a good-material outlet and a bad-material outlet; a rotary piston rotatably mounted in the housing and configured to guide the material stream from the material inlet to the good-material outlet or to the bad-material outlet depending on the detection result of the detection device; a drive unit configured to position the rotary piston at least in a first and a second rotary position; wherein the drive unit is configured to rotate the rotary piston between the first rotary position and the second rotary position by an angle of rotation greater than 90°.

Abstract: A facility for generating a detection signal upon the presence of metallic-conductive parts in a conveyed flow that is at least largely non-conductive, in which, for example, an alternating electromagnetic field is established in a section of the conveyed flow to be monitored by means of an alternating current generator and a transmitter coil system, whereby a variation of the signal of said field that is triggered by passage of a part is detected by a receiver coil system and converted into a detection signal by an analytical circuit. The individual components of the system are distributed over separate circuit modules which in turn act in concert by means of a bus system.

Abstract: A stackable roll container, in particular, for transporting foods, cosmetic articles, or other articles in large bundles. The stackable roll container includes a preferably rectangular bottom component, with transport rollers mounted on the underside. The stackable roll container also includes two attachment walls located opposite each other on opposite lateral sides of the bottom component. Each attachment wall extends upwardly from an upper side of the bottom component and has a respective rear vertical end brace which is offset from a vertical base plane of the respective attachment wall. Each attachment wall also includes a lower horizontal base brace adjoining the respective rear vertical end brace for that attachment wall.

Abstract: A facility for generating a detection signal upon the presence of metallic-conducting parts in a conveyed flow that is at least largely nonconductive, in which an alternating electromagnetic field is established in a section of the conveyed flow to be monitored by means of an alternating current generator via a transmitter coil system, whereby a variation of the signal of said field that is triggered by passage of a part is detected by a receiver coil system and serves, in conjunction with a downstream digital-type analytical circuit, for derivation of a detection signal which then triggers an information and/or elimination of said part. The receiver coil system has an analog-to-digital converter assigned to it and the transmission of the received signal to the analytical circuit proceeds in digital form.

Abstract: A device for monitoring a product stream for undesired inclusions wherein, in a section of the product stream which is to be monitored, a material-specific detection signal is derived by means of a sensor system comprising a plurality of sensors arranged in a staggered manner under formation of a sensor row in the direction of transport of the product stream and by means of an evaluation circuit associated with said sensor system, by simultaneously adding the output signals of the individual sensors in an addition circuit in a correlated manner, said output signals originating from single products with regard to metal particles in the product stream to be checked, and using the output signal of the addition circuit as a detection signal for a metal particle to be discovered. At least one sensor of a sensor row, the output signals of which are added in an antiphase manner to the output signals of other sensors for difference-taking purposes, is provided for the compensation of interfering magnetic fields.

Abstract: A device for producing a detection signal when interfering, preferably metallic conductive pieces occur in an at least largely non-conductive conveyor stream. An alternating electromagnetic field is built up by an alternating current generator through a transmission coil in a segment of the conveyor stream to be monitored. The changes in amplitude and phase of the alternating electromagnetic field are detected by a coil system that feeds an evaluating circuit for deriving the detection signal, which, when an interfering piece appears, causes a stoppage of the conveyor stream for the purpose of removing the interfering piece. A resetting device (reset button) is also provided which is able to cancel the conveyor stoppage. A device is also provided for blocking the resetting device, controlled by the evaluating circuit, which disables the resetting device as long as the evaluating circuit still emits a detection signal.

Abstract: A device is provided for generating a detection signal upon occurrence of metallically conductive parts in an at least substantially non-conductive conveyor stream in which device an electromagnetic alternating field is established by an alternating current generator via a transmitting coil system in a section of the conveyor stream to be monitored, the amplitude and phase variations of the alternating field triggered when a part passes being detected by a receiving coil system and a subsequent evaluation circuit in the form of a phase variation signal and an amplitude variation signal. A stage for vectorial addition of the two variation signals and a phase comparator are provided. On the one hand, the vectorial composite signal is fed to the phase comparator, and on the other hand, one of the two variation signals is fed to the phase comparator. The output signal (phase angle signal) corresponds to the phase angle between the vectorial composite signal and one of the two variation signals.
