Definitions

  • the invention relates to a rotatable separating drum, which is suitable for separating different parts, in particular for separating injection-molded and sprue parts.
  • An apparatus for mechanically separating individual parts of different shape and size is known, for example, from DE 26 37 851 C2.
  • This device consists of a rotatable and obliquely mounted drum cylinder which is open on both end faces and whose lateral surface is composed of longitudinal bars which are arranged at a distance from one another and are mounted in two side rings so as to be rotatable about their longitudinal axis.
  • the longitudinal bars are designed as shell rollers rotating in opposition to the circulation direction of the drum cylinder.
  • This separating device has a first group of longitudinal bars, which are fixedly mounted on two blanks, that is, side rings.
  • the separating device has a second group of longitudinal bars, the positioning of which, in contrast to the first group, is adjustable relative to the rounds. All longitudinal bars rotate opposite to the total direction of rotation when circulating in the separating drum.
  • the longitudinal bars of the second group are coupled to the longitudinal bars of the first group via planetary plates. With the aid of an endless chain, the position of the longitudinal bars of the second group relative to the longitudinal bars of the first group can be changed. This allows a quick adjustment of the distance between the longitudinal bars.
  • a separating device which comprises a clearing device.
  • the clearing device serves to clear a clear cross section of a separating slat in at least one position during the rotation of the separating drum.
  • the Separierkulisse is formed by step-like walls, wherein we least one wall of the Separierkulisse is designed to be movable.
  • the invention has for its object to provide a comparison with the prior art further developed, simple design and manageable, as well as versatile usable Separiertrommel, which is particularly suitable for use in injection molding machines to specify.
  • the separating drum comprises a substantially cylindrical, separating frame which can be rotated about an axis.
  • a plurality of change segments can optionally be connected to the separation base frame or detached from it non-destructive. Once the change segments are attached to the separation base, there is no relative movement between the change segments and the separation base. Openings for separating the various parts, in particular for separating injection-molded parts and sprue parts, are formed exclusively by the exchange segments. An adjustment mechanism of the separation base frame is therefore not necessary. In order to change the separating drum from a first separating task to a second separating task, only the changing segments have to be exchanged, which in a preferred embodiment is possible without tools.
  • the change-over segments have a very low weight, which makes it easier to retrofit the separating drum compared to a complete drum replacement.
  • the Separleitersgrundgestell which is useful for a variety of separation tasks, preferably has a polygonal cross-section.
  • the separation base frame in cross-section describes a polygon having at least six and at most sixteen corners, for example a 12-corner.
  • the number of alternating segments preferably corresponds to the number of sides of the polygon.
  • Theoretically embodiments are also feasible in which not on each side of the polygonal separation base frame, a change segment is fastened, so that the number of change segments is less than the number of sides of the polygon. In such cases, the remaining sides of the polygon can either be designed as closed walls from the outset or closed by covers, so that they have no separating function.
  • the individual exchange segments preferably each have an elongated, rectangular basic shape, wherein they are provided for resting on a respective strip-shaped, an elongate opening having wall portion of the separating base frame. Outside the elongate opening, the change-over segment preferably lies flat on the wall section, so that there can be no catching of parts in the corresponding areas.
  • the change segments are designed as insertion segments provided for attachment to the separation base frame, wherein the connection between the base frame and insertion segment can be produced and released by at least slight displacement of the insertion segment in the longitudinal direction of the base frame is.
  • connection technologies are suitable, which either require the assistance of a tool or are designed as a tool-less mechanism. Examples include closures with magnets, ball retainers and snap fasteners.
  • closures with magnets ball retainers and snap fasteners.
  • the wall sections of the separating base frame which each have only a single, elongate opening in a preferred embodiment, there are preferably a plurality of openings, for example in the form of circular recesses, in each changing segment, in particular insert segment
  • the openings in the exchange segment are arranged, for example, in a single row or in a plurality of rows which are aligned or aligned parallel to the center axis of the separation base frame.
  • the advantage of the invention lies in particular in the fact that a single separating drum can remain over a long period of time and for a wide variety of changing separating tasks in a separating device, which is assigned in particular to an injection molding machine. Only different sets of interchangeable segments, in particular in the form of slide-in segments, which can be stored in a very small space and can be handled in a simple manner, are to be combined with the separating base frame, that is to say the rotatable drum.
  • Fig. 2 is a suitable for use in the separating drum of Fig. 1
  • a separating drum designated as a whole by the reference numeral 1 is provided for separating gate parts and good parts which are ejected by an injection molding machine.
  • the separating drum 1 has a basic cylindrical shape and is rotatable about its own longitudinal axis.
  • Two connection areas 2, 3 on the front sides of the separating drum 1 are used for embedding the separating drum 1 in a surrounding construction, not shown. tion.
  • the connection areas 2, 3 are connected via rings 4, 5 to a central drum area 6, which assumes the intended separating function.
  • the middle drum region 6 is formed from strip-shaped wall sections 7 which each have an elongated opening 8 extending approximately over the entire drum region 6.
  • a total of twelve strip-shaped wall sections 7 are present, which together describe a 12-corner.
  • the 12-cornered basic shape of the separating drum 1 continues into the connection areas 2, 3.
  • the connection areas 2, 3, together with the rings 4, 5 and the central drum area 6, form an inherently rigid separation base frame 10. If the good parts are so large that they can not fall through the openings 8 in the strip-shaped wall sections 7 , the separating base frame 10 can already be used as a separating drum 1. In practice, however, the use of additional insertion segments 9 is required in most cases, which are placed on a respective strip-shaped wall section 7 and fixed there.
  • FIG. 9 An insulated insert segment 9 is shown in FIG. Individual, in each case circular openings 11, which take over the desired separating function, are arranged within the insert segment 9 in a single row, which is aligned parallel to the central axis, that is to say the axis of rotation, of the separating base frame 10. Depending on the separation task, several rows of openings 11 in the insertion segment 9 could also be present.
  • each insertion segment 9 has fastening contours 12 which correspond to counter contours on the sides of the separation base frame 10 and enable simple and stable assembly of the insertion segments 9 on the separation base frame 10 .
  • the insertion segments 9 are replaced by a Front side of the separation base frame 10 from each pushed through one slot-shaped opening in one of the rings 4, 5 to the central drum portion 6 and fixed there.
  • the insertion segment 9 can be removed from the separation base frame 10 in this case.
  • different sets of slide-in segments 9 are storable with a small footprint in the vicinity of the injection molding machine, which is associated with the separating drum 1.
