Definitions

  • the invention relates to a separating drum with a plurality of cylindrical separating elements, which are arranged parallel to the axis of the drum, and of which a part is displaceable to form an adjustable separating gap.
  • Separating drums of this type are known, for example, from DE 26 13 088 A1 or US Pat. No. 4,084,697 and are used for separating a wide variety of parts. Therefore it is often necessary to change the drum, i.e. readjust the size of the separating column on the circumference.
  • the invention has for its object to develop a separating drum with a plurality of separating gaps distributed over the circumference such that the setting the column can be done centrally with a simple structure.
  • the object is achieved by combining the following features: the separating elements are each firmly connected in pairs by at least one carrier element which is provided on one of the end faces of the separating elements, the carrier element can be pivoted about the axis of a cylindrical separating element lying in the circumference of the drum, - On at least one end face of the fixed separating element, a setting wheel is provided in the pivot axis, which can be driven by means of a rotating setting element for setting the separating gap.
  • This combination of features makes it possible, when changing the parts to be separated, to reset the separating column in a single setting process by driving the rotating setting element.
  • the setting process can be carried out automatically either by hand or via a process control unit.
  • a particularly simple embodiment of the setting wheel and the rotating setting element is specified, according to which the setting wheel is a sprocket and the setting element is a chain which can be driven by a drive.
  • the setting wheel is a sprocket and the setting element is a chain which can be driven by a drive.
  • the setting wheel is a sprocket and the setting element is a chain which can be driven by a drive.
  • a toothed belt or a similar peripheral element, such as a V-belt as the peripheral element; however, the use of a chain has cost advantages over toothed belts, particularly in small series production.
  • separating drums in which the cylindrical separating elements are attached to the carrier element in a fixed manner, ie not rotatable about their axis.
  • the configuration according to the invention can be implemented particularly advantageously, since, for example, the carrier elements have a simple structure.
  • FIG. 1 a and b show a front view of a separating drum 1 for separating parts not shown in FIG. 1.
  • the separating drum has in its circumferential surface cylindrical separating elements 2 'and 2 ⁇ , which in the exemplary embodiment shown are not rotatably mounted about the cylinder axis, that is to say represent "fixed rollers".
  • a separating element 2 'and an element 2 ⁇ are connected by a carrier element 3, which is shown in more detail in Fig. 2.
  • the carrier element 3 is pivotally mounted about the axis of the element 2 'on the end face of the separating drum 1.
  • Fixed to the carrier element 3 or the separating element 2 ', a sprocket 4 is connected.
  • a chain 5 is stretched over the sprockets 4 of the individual carrier element 3 distributed over the circumference of the drum 1 and can be driven by means of a drive (not shown in more detail).
  • the chain 5 can be fixed by means of an element 6 shown in more detail in FIG. 3.
  • the element 6 has two clamping disks 7 'and 7' for the chain 5, which are connected by an Allen screw 9 screwed into the end wall 8 of the drum 1 and are pressed apart by a spring 15.
  • an Allen screw 9 screwed into the end wall 8 of the drum 1 and are pressed apart by a spring 15.
  • the exemplary embodiment shown has separating lamellae 10, which are fixedly attached to the drum housing by means of a strip 12 and are arranged in each separating gap “opposite” the pivotable separating element 2 ⁇ .
  • the shape of the roller gap between the pivotable separating element 2element and the lamella 10 according to the invention ensures that even parts 13 of complex shape to be separated, such as the "H-shaped" part shown in FIG. 4 with molded sprue 14, without " Jamming "etc. can be separated.
