Provided is a combination weigher which can prevent damages to objects which are broken or damaged easily, due to an impact or the like, generated when they are dropped. A combination weigher according to an embodiment of the present invention comprises a plurality of weighing conveyors (1) which are manually fed with objects and conveys the objects fed manually; a plurality of weight sensors (2) provided to correspond to the weighing conveyors (1), respectively, to measure weights of the objects held on the weighing conveyors (1); a control section (5) which finds a discharge combination including a combination of the weighing conveyors (1) holding the objects in which a total weight thereof falls within a target weight range, based on weight values of the weight sensors (2) and activates the weighing conveyors (1) selected to make up the discharge combination to convey the objects on the weighing conveyors (1) in a first direction and discharge the objects from one ends of the weighing conveyors (1); and a collecting conveyor (3) which is fed with the objects discharged from the one ends of the weighing conveyors (1), conveys the objects in a direction, and discharges the objects.

A control for a continuously moving weighing conveyor first triggers on a predetermined sensed weight (104). The control determines a first inflection point on the weight waveform defined as the "maximum positive slope" (106). Then the control begins recording weight samples at a sampling rate. The control checks the weight waveform of sampled weights for a slope which is a first pre-selected percentage of the maximum slope but negative in slope value "weight-off-scale" point (110). The control then looks backward through the recorded data of weight samples to find another point which has a slope which is a second preselected negative percentage of the maximum positive slope "end sample position"(114). Then a "start sample position" (118) is determined to fall within, or at the start of, a flat region of the waveform. The values within the sample period are then averaged to determine a static weight.

Die Erfindung betrifft eine Waage (1) zum automatischen Wiegen von strangförmigem Wiegegut (7), mit einem Zuführband (2) und einem Abführband (3) zum Transport des Wiegeguts und mit einer zwischen Zuführband und Abführband angeordneten Rolle (41) als Gewichtsaufnehmer. Das Gewichtssignal wird über die Zeit integriert um das Gesamtgewicht des Wiegeguts zu bestimmen. Um den Startzeitpunkt bzw. Stoppzeitpunkt zum Bestimmen des Gewichts automatisch festzulegen, werden diese anhand der Ableitung des Gewichtssignals nach der Zeit bestimmt.

The invention relates to an extraction plant, e.g. for used shredded tyres, coarsely ground municipal waste, commercial waste, papers, textiles, etc. The plant of the invention includes a hopper (12) for storing a certain amount of product to be extracted, an extractor (20) for pushing said product towards the front end (24) of said extractor (20), a trimmer (21) located in the area of the extractor front end (24) above said extractor (20) and rotating in a direction adapted for sending a portion of said product back into said hopper (12). The plant is characterised in that the trimmer (21) includes pushing means for sending a portion of said product back into the hopper (12). The present invention also relates to an extraction method and to a metering method for an extraction plant according to the present invention.

Verfahren zur Bestimmung der Reinheit von aufbereitetem Altglas, bei dem die Probenmenge aus dem aufbereiteten Altglasstrom entnommen und einlagig aufgeschüttet und über eine Freifallstrecke rieseln gelassen, und die Fremdkörper nach Nichteisen-Metallen und opaken Fremdstoffen nach einer getrennten Erfassung ausgeblasen und gewogen werden und die Verhältniszahlen von Nichteisen-Metall-Beimengungen zur gesamten Probenmenge, bzw. der opaken Fremdstoffe zur gesamten Probenmenge ermittelt werden. Um ein solches Verfahren besonders einfach durchführen zu können, ist vorgesehen, daß die Fremdstoffe gemeinsam kontinuierlich gewogen und die Gewichtszunahme je nach dem welche Art von Fremdstoffen, Nichteisen-Metalle oder opake Fremdstoffe, erfaßt wurde, die Gewichtszunahme der Fremdstoffe dieser erfaßten Gruppe zugezählt wird.
