Definitions

  • the present invention relates to a device according to the preamble of claim 1 for pulling out or twisting off Closure of vessels, especially sample vessels.
  • Devices for removing closures from vessels are used particularly in the field used in clinical analysis, since a large number of sample vessels are produced here, which are closed with plugs or screw caps, which are carried out before carrying out a Analysis must be removed.
  • This apparatus has a holding device for the sample vessels, as well as a mechanism with which the stopper from 2 opposite holding jaws are included.
  • a holding device for the sample vessels as well as a mechanism with which the stopper from 2 opposite holding jaws are included.
  • thorns are also inserted into the stopper, which provide a secure mounting enable.
  • the stopper is removed by the device with the holding jaws behind is removed from the top of the sample vessel.
  • No. 4,876,926 is a generic device for removing plugs is known in which a sample vessel is held with holding jaws, while the stopper by means a holding device is turned off.
  • the holding device has a large number of metal tips, which partially penetrate the plug and it during the calibration process keep.
  • the object of the invention was to propose a device with which both the removal of plugs as well as screw caps is possible. It was still the job of Invention to propose a device with which any used in practice Sample containers can be released from their closures.
  • a sample vessel is placed in the vessel receiving device of the device according to the invention so that it is possible to remove a closure. This presupposes that the vessel receptacle supports a counter bearing when pulling out or twisting forces occurring.
  • the vessel receiving device must accordingly be designed in this way be that both rotational movements and linear movements of the vessels are largely prevented.
  • the sample vessels used are in usually around glass or plastic test tubes.
  • the vascular cradle must therefore be designed so that it does not exert too much pressure on the sample vessel exercised, a holder causes to prevent destruction of the sample vessel.
  • a suitable device for holding test tubes is, for example, in EP-B-0 264 456.
  • a vessel receiving device was advantageous as found particularly suitable in which the reagent vessels between holding jaws are relatively elastic material, e.g. B. rubber, are clamped.
  • the holding jaws are in turn attached via an axis to adjusting jaws so that they are opposite the axis of the vessel can be tilted. It has proven to be particularly simple if the adjusting jaws are moved towards or away from one another via a spindle drive in order to accommodate the vessel receiving device to open and close.
  • a spindle drive for a couple of adjusting jaws can advantageously be operated with a single motor if the Spindle drive for both adjusting jaws is housed on a single threaded rod, a right-hand thread on one section and a left-hand thread on the other section owns.
  • the described vessel receptacles can be used together with racks for sample vessels operate.
  • racks used in practice several test tubes arranged linearly one after the other.
  • Such a rack can operated together with a vascular cradle by the rack is pushed between the holding jaws of the vessel receiving device. Is this Rack designed so that the sample vessels are accessible from the side, so the Sample vessels are held by the holding jaws without having to remove the Sample vessels are necessary to remove the closure.
  • a sample rack is placed on a conveyor belt pushed through which the individual vessels one after the other under the closure holder be moved through.
  • a vessel which is located under the closure holder, is lifted by a gripper arm and the closure of the vessel in the closure holding device guided. It has been shown that the gripper is cheap mechanically relatively simple to design and to hold the vessel during of the calibration process to provide a separate holding device.
  • This vessel holder can be arranged fixed in space due to the additional gripper.
  • the rotors used by some devices for sample vessels in which the Sample vessels arranged on a circular line can be used together with the described vessel receptacles are used provided the vessels of the Side are accessible.
  • the sample vessels it is also possible to remove the sample vessels to remove any racks with a robotic arm and into the vessel holder adjust.
  • a vessel receiving device has been found to be advantageous which consists of two receptacles, which together on a rotating arm are attached.
  • One of each of these two vessel receiving devices is located in a position accessible to the lock retainer, typically below the locking device.
  • the second vessel receiving device is on a position in which it can be filled with closed sample vessels. Is this vessel in the first position has been opened and there is a closed vessel in the second position, the rotary arm rotates with who swapped the two positions. Now the still closed vessel can can be opened and the already opened vessel can be used for subsequent analysis to be transported further.
  • the device described is particularly suitable to in to integrate a transport system in which the sample vessels individually contain a large number of Pass through stations in which, for example, labels are attached, pipetting, Dilution and centrifugation steps are carried out.
  • a locking device is equipped with holding elements for holding serve a closure.
  • the closure holding device in the Figures 11 to 15 shown device of the European patent EP-B-0 264 456 described device or a similar device can be used.

  • the first position is usually chosen for the sake of simplicity so large that all that occur in practice Closures fit between the gripper jaws.
  • driving the gripping jaws it can are, for example, pressure cylinders or a spindle drive. It however, a drive was found that could easily grip all gripping jaws simultaneously emotional. This drive has two plates arranged in parallel with each other Disk drive can be rotated against each other perpendicular to their plane.
