Definitions

  • Transport shaft and dispensing device The present invention relates to a transport shaft according to the features of the preamble of claim 1 and a dispensing device for a separating and filling device according to the features of the preamble of claim 20.
  • the invention further relates to a separating device with a transport shaft and a separating and filling device with a separating device with a transport shaft.
  • transport shafts or spirals are used to move objects further, with the objects being transported by means of a thread running on the transport shaft.
  • such transport shafts can be designed in such a way that the objects are separated or separated from one another during transport.
  • An application in practice can be that a quantity or a pile of unstructured or chaotically arranged tubes, such as pipette tips or sample tubes, is to be counted and/or structured and/or separated into a container, such as a perforated grid, a carrier plate, a box, crate or the like is to be sorted.
  • a container such as a perforated grid, a carrier plate, a box, crate or the like
  • the tubes such as pipette tips and/or sample tubes
  • Transport shafts of the type mentioned are known, for example, from the sorting system in US 7861845.
  • This sorting system is primarily designed to transport rounded objects with essentially convex surfaces, such as tablets, one after the other and to deposit them at the end of the transport shaft.
  • the objects are handed over individually to another facility, the objects are not necessarily spaced or separated from one another during the transfer.
  • the objects can be counted, controlled separation, sorting into a container or a reject or the removal of several unintentionally connected objects is not possible due to the transport shaft used.
  • a separation system for pipette tips is known from the document AT 522525, which comprises a feed device for feeding pipette tips, a dispensing device for dispensing pipette tips and a separating device arranged between the feed device and the dispensing device, the separating device having a rotatably mounted transport shaft with a thread having.
  • the thread is designed in such a way that the pipette tips are transported or pushed forward both in a frictional manner and, in particular on both sides and/or completely, in a form-fitting manner.
  • the form-fitting can lead to wedging, jamming or the like, which of course has an unfavorable effect on the separation and/or transport process in many respects.
  • dispensing or filling and sorting the objects into a container in particular threading and/or dropping the tubes into a grid, can pose challenges.
  • this has to do with the design or geometry of the grid, such as a hole grid, in which the tubes are usually sorted relatively close to one another after they have been separated using a separating device with a transport shaft.
  • how easy or difficult it is to dispense or sort into a grid depends on the design or geometry of the tubes.
  • the dispensing and threading process is particularly difficult due to their compact shape with a relatively wide and/or rounded tip, especially because the width or diameter is relatively large in relation to usual grid openings.
  • Jamming and the like can occur as problems when filling the sample tubes, whereby the filling process may have to be stopped and/or interrupted, which in turn can lead to delays in the filling process.
  • problems that are particularly associated with elongated and/or at least partially hollow objects have not yet been solved or have only been solved in an unsatisfactory manner.
  • the object of the present invention is therefore to provide a solution that is improved over the prior art for the handling, in particular the precise separation and filling, of elongated objects, such as pipette tips and/or sample tubes.
  • elongated objects such as pipette tips and/or sample tubes.
  • One aspect of this object is achieved with regard to the present invention by the features of claim 1, namely with a transport shaft for the transport of elongated objects, in particular pipette tips, preferably for a separating device, having - an open thread with a thrust flank side and a counter flank side, and - a hanging area with a first core diameter for receiving the objects, and - a separating area arranged after the hanging area, in which at least part of the thread runs, characterized in that the transport shaft in the separating area - a running area wound along the thrust flank side of the thread with at least the first Core diameter and - a winding recess area different from the running area with at least a second core diameter, the second core diameter being
  • a further aspect of this object is achieved by the features of claim 20, namely with a dispensing device for a separating and filling device, which dispensing device is designed for dispensing objects, in particular sample tubes, into a container, the dispensing device comprising at least one clamping device, which is designed to at least temporarily clamp the objects and / or insert them into a container, characterized in that the clamping device comprises at least one spring-loaded collecting comb. Protection is also sought after for a separating device with a transport shaft according to the invention that is rotatably mounted about a longitudinal axis.
  • a separating and filling device for elongated objects comprising - a feeding device for feeding the objects, the feeding device preferably comprising a rotatably mounted drum, and - a dispensing device for dispensing the objects, preferably for precise transfer the objects into a container, and - a separating device according to the invention arranged between the feed device and the delivery device.
  • the great advantage of the transport shaft according to the invention is that, at the same time as the transport in the longitudinal direction, an effective separation of the objects and sorting out of unwanted unseparated objects, in particular objects lying against one another, is possible. By separating and sorting out, individual objects that are spaced apart from each other can be transported further in a controlled manner.
  • the second core diameter in the recess area being smaller than the first core diameter in the running area, only isolated or separated objects are transported further on the shear flank side of the thread, and further objects which are connected to another object are inconveniently connected and/or arranged adjacent to one another, fail.
  • a control device is particularly preferably provided, which is explained below.
  • a further advantage of the transport shaft according to the invention is that the objects are transported, in particular due to the open thread with spaced threads, by pushing them further in a mainly frictional manner using the push flank side.
  • the transport shaft according to the invention causes significantly less wedging or jamming of the objects, as would be the case, for example, with a closed thread in which there would be a positive connection on both sides and/or completely. Reducing or avoiding wedging also advantageously reduces the occurrence of possible damage or destruction of the objects.
  • the great advantage of the dispensing device according to the invention is that extremely precise clamping and alignment of the objects and/or groups of objects is made possible, so that sorting the objects into a container, in particular a grid, is significantly simplified.
  • sample tubes are usually relatively short and therefore only barely or not at all protrude from the space between a filling shaft and a holding element and are therefore difficult to clamp.
  • the collecting comb according to the invention which is temporarily, in particular by means of at least one spring, spring-loaded, the Objects, in particular sample tubes, are dropped from the gap and are caught by at least one collecting comb. As a result, they can be clamped much more stably and precisely by means of the at least one clamping area and/or the at least one collecting comb of the clamping device.
  • the objects protrude further from the clamping device, which means that they can be aligned and/or threaded into the container much more easily, especially in relation to the openings of a container.
  • the objects are dropped from the gap into at least one collecting comb, preferably two collecting combs, whereby the objects protrude far enough from the clamping device to be clamped stably and/or precisely and/or sorted into a container.
  • the clamping device in particular the at least one clamping area and/or the at least one filling area, is further closed to clamp the objects, which is followed by the objects being threaded into the container and the objects being delivered to the container.
  • the at least one spring is relaxed at the beginning of the first step of the clamping process, when the objects are hanging in the at least one collecting comb and are still unclamped. It means that the at least one collecting comb is not yet spring-loaded at this point in time. Only and only when the at least one collecting comb clamps the objects is the at least one spring tensioned, which means that the at least one collecting comb is spring-loaded.
  • the clamping device is preferably designed in such a way that the area on which the objects are clamped is enlarged by the at least one collecting comb, so that increased stability is provided during the temporary clamping, in particular threading into a grid being made easier.
  • the transport shaft according to the invention and the delivery device according to the invention enable significantly gentler and/or more precisely controlled handling of the objects.
  • the operating times can be increased and the interruption times can be reduced.
  • Elongated objects can be, for example, pipette tips or sample tubes, but also other objects.
  • an elongated object may have a tapering and/or changing diameter along its longitudinal axis.
  • a diameter is not necessarily to be understood literally as the diameter of a circle or circular cross-section, but can also be an average or maximum diameter over the cross section of the elongated object.
  • An elongated object can have a closed surface or can be at least partially open and/or hollow, as is the case, for example, with pipette tips or sample tubes.
  • An open thread is usually characterized by the fact that the thread and its flanks, such as the thrust flank side and the counter flank side, are wound at a distance along a shaft or screw. In other words, this means that the thread turns wind around the shaft at a distance from each other.
  • the thrust flank side is to be understood as that side of the thread flank by means of which the objects can be pushed further purely and/or mainly in a frictional manner.
  • the counter flank side is the side of the thread flank opposite the shear flank side.
  • the hanging area is that section of the transport shaft in the longitudinal direction to which the objects are fed and in which they hang.
  • the hanging area is designed in such a way that the objects hang in and align themselves, in particular independently due to their shape and/or their center of gravity, in such a way that the respective longitudinal axes of the objects are aligned essentially orthogonally to the longitudinal axis of the transport shaft.
