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 can be displaced to form an adjustable separating gap.
  • Separating drums are known, for example, from DE-A-26 13 088 or US-A-4 084 697 and are used for separating a wide variety of parts. Therefore it is often necessary to change the drum, ie re-adjust the size of the separation column on the circumference.
  • this separating drum has the disadvantage that the position of the gap which is effective for the separating process along the outer contour of the fixed rods, i. for example, moves on a circular path.
  • the parts to be separated thus move on a curved path, so that in particular complicated-shaped parts easily get caught or jammed.
  • the invention has for its object to develop a separating drum with a plurality of separating gaps distributed over the circumference in such a way that the setting of the gaps can be carried out centrally with a simple construction without the parts being easily caught or jammed.
  • the setting process can be carried out automatically either by hand or via a process control unit.
  • the fact that the pivotable separating element and a separating lamella fixedly attached to the drum form the separating gap ensures that even complex-shaped parts which, for example, have sprues or the like, cannot "get caught” in the separating arrangement.
  • 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, especially in small series production.
  • the cylindrical separating elements are attached fixedly, that is to say not rotatably about their axis, the configuration according to the invention can be implemented particularly advantageously and there is in particular a simple construction of the carrier elements.
  • 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 cylindrical separating elements 2 'and 2' 'in its peripheral surface, 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 on the end face of the separating drum 1 about the axis of the element 2 '.
  • a sprocket 4 is fixedly connected to the carrier element 3 or the separating element 2 '.
  • 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.
  • the chain can be clamped by tightening the screw 9; if, on the other hand, the screw 9 is loosened, the chain 5 runs freely through the fixing element 6.
  • 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 sprocket 4 assigned to each carrier element 3 is rotated and the carrier element is thus pivoted in the direction of the arrows 11 ′ or 11 ′′.
  • the width d of all the separating gaps formed between the separating lamellae 10 and the pivotable separating elements 2 ′′ is increased or decreased to the same extent. Since all the chain wheels 4 are connected via the chain 5, the individual separation gaps are changed synchronously and centrally via a single (not shown) drive for the chain, which can be constructed as a conventional chain drive.
  • the inventive shaping of the roll gap between the pivotable separating element 2 ′′ and the lamella 10 ensures that even parts 13 of complex shape to be separated, such as the “H-shaped” part shown below in FIG. 4, with molded sprue 14, without “Jamming” etc. can be separated.
