Definitions

  • the invention relates to a device according to the preamble of claim 1 for the automatic removal of the closure of vessels, which are arranged in groups in vessel carriers and successively fed to the frame of the device, in particular the stopper closure of sample vessels for medical or technical tests, in which a Component engaging the closure is moved towards the closure and the closure is then released from the vessel with this component, a receptacle for the vessel carrier being arranged under this component, a drive being provided for the gradual movement thereof.
  • vessel carriers are usually plate-like or rack-like, but special shapes are also used.
  • These vessel carriers are inserted into the device and are passed step by step past the components which remove the stopper, one sample after the other being freed from the stopper.
  • the plug is removed by means of a mandrel that pierces the plug, which, after piercing, pulls the plug out of the tube, whereupon the plug is stripped from the mandrel and discharged through a tube from the device.
  • a disadvantage of the known device is that it can only be used for a single type of vessel carrier. If the sample vessels are in a type of vessel carrier that differs from the type of vessel carrier belonging to the device, the device cannot be used for this new type; a device that matches the new vessel carrier type must then be used. In practice, however, it is often not predictable or determinable on which type of vessel carrier the sample vessels are delivered, so that in practice several devices are often required in quick succession, depending on the type of vessel carrier supplied. This requires not only an increased expenditure on devices, but also an increased space requirement, which cannot always and everywhere be taken into account.
  • the object of the invention is to avoid these disadvantages and to make a device of the type described above more universally usable, so that one and the same device can be used for processing sample vessels held on different types of vessel carrier.
  • the invention solves this problem in that the receptacle is arranged on a separate frame which can be separated from the frame of the device and which has its own electric motor for moving the vessel carrier, the two frames being able to be coupled to one another by means of connecting elements and these connecting elements being used for electrical coupling of the electric motor for the vascular support with the electrical system provided in the frame of the device and that different receptacles are provided on separate frames for different vascular supports, which can optionally be connected to the connecting links or the electrical coupling.
  • the outlay for the treatment of different types of vessel carriers is reduced to the different receptacles or their frames, which represents a substantial saving compared to the device described at the beginning.
  • the change from one type of recording to another type of recording and thus from one type of carrier to another can be carried out quickly and the own motor for the movement of the respective carrier makes complicated kinetic transmission elements between the two frames unnecessary.
  • the connection between the two frames is therefore reduced to the connecting links which hold the two frames to one another in such a way that a relative shift in operation is not possible, and to the electrical connection, which on the one hand serves to power the electric motor of the mounting frame, on the other hand to control this electric motor from the main unit according to the function of the components removing the closure.
  • the connecting links have hooks on the frame of the device, into which bolts of the frame of the receptacle can be hung, the hook openings preferably being directed upwards.
  • the hooks are arranged on lateral brackets which are pivotably guided on the frame of the device and which form a quick-release fastener.
  • the electrical coupling is also expediently formed by a plug connection, which is generally designed as a multiple plug.
  • a particularly favorable embodiment results from the fact that the plug connection is provided on the mutually facing sides of the two frames and is secured in the connection position by means of quick-release fasteners arranged on both sides. This results in a locking of the two frames to one another, which is secured both in the insertion direction of the plug connection and transversely thereto.
  • FIG. 1 shows the device with two different holding racks with assigned different vessel carriers, namely a plate and a rack.
  • the individual frames are shown separately from each other.
  • 2 shows the receiving frame for a turntable placed thereon in the state connected to the device frame.
  • 3 shows a side view of the connecting links in the separated state of the two frames.
  • 4 shows the two frames in a vertical section in the coupled state, the holding frame showing a rack for the sample vessels, the rack removal device being in the piercing position of the mandrel.
  • 5 shows a vertical section similar to FIG. 4, but after the plug has been pulled out of the sample vessel, and for a vessel carrier formed by a turntable.
  • Figure 6 is a vertical section similar to Figure 5, but in the position shortly after the plug has been removed from the mandrel.
  • a frame 1 carries the plug removal device, which is essentially enclosed by a housing 2.
  • the front 3 of the frame 1 is connected to a further frame 4 by means of connecting links 5 can be coupled in such a way that the two frames 1, 4 rest against each other without a gap (Fig. 2).
  • different vessel carriers 6 are to be used for the sample vessels 7 formed by cylindrical glass tubes, different frames 4 are provided, corresponding to the different types of vessel carriers 6, of which only two types are shown in FIG. 1 for the sake of simplicity, namely on the one hand a turntable 8 and on the other hand a rack 9.
  • Each of these frames 4 also has a housing 10 enclosing its components.
  • the connecting links 5 have a quick-release fastener, which has two brackets 11 which are guided laterally on the housing 2 of the frame 1 (FIG. 3) and are formed with hooks 12 at their ends facing the frame 4, the hook openings 13 of which are directed upwards. Bolts 14 projecting laterally from the housing 10 of the frame 4 can snap into these openings 13. Furthermore, the connecting members 5 have an electrical coupling 17 in the form of a plug-in connection, with which the electrical system of the plug removal device accommodated in the frame 1 can be connected to a separate electric motor 18 (FIGS. 4 to 6) provided in the frame 4 for the vessel carrier 6.
  • brackets 11 are provided with elongated holes 16 in which pins 15 arranged on the side surfaces of the housing 2 slide, about which the brackets 11 can be pivoted.
  • Each bracket 11 is articulated at its end facing away from the opening 13 to a link 19 which is pivotably mounted on the housing 2 at 20.
  • the two side links 19 are connected to each other on the back of the housing 2 and provided with a handle 21 to facilitate operation.
  • the handlebars 19 together with the brackets 11 form a toggle-like clamping connection which, after the bolts 14 have been suspended in the openings 13 when the handle 21 is pressed down, brings the two mutually facing surfaces of the two frames 1, 4 or their housing into tight contact with one another and so the plug connection of the coupling 17 secures in the inserted position as soon as the handle 21 has been depressed in the direction of the arrow 22 (FIG. 2).
  • the handle 21 is swiveled up in the direction of the arrow 23 (FIG.
  • Each frame 4 or its housing 10 has a receptacle 24 which is adapted to the respective vessel carrier 6 and the motor 18 transports the vessel carrier 6 guided in the receptacle 24 step by step, so that the sample vessels 7 carried by the vessel carrier 6 in turn from their closures 40, in particular Plug closures, can be exempted (Fig. 4 to 6).
  • the step-by-step movement can easily be achieved by correspondingly controlling the electric motor, only the achievement of the desired position having to be ensured by suitable means.
  • a stepping mechanism 25 FIG. 4 engaging in the receptacle 24 is required.
  • the plug removal device accommodated in the housing 2 of the frame 1 has an electric motor, not shown, which is fed by the electrical system of the plug removal device carried by the frame 1 and at the same time forms the drive for a drive and control disk 26 which carries an eccentric pin 27 which is in a longitudinal slot 28 of a pivot lever 29 slides, which is pivotally mounted at 30 in the frame 1. At its free end, this pivot lever 29 is forked and drives a pin 31 of a slide 32 which is slidably mounted in a horizontal guide 33.
  • the slider 32 carries an upward-facing extension 34 to which a rod 35 is articulated, which is guided approximately in the middle of its length by means of a guide roller 36 on a link 37.
  • the rod 35 can thus be moved back and forth in the horizontal direction and its front end can be pushed out of the housing 2 through an opening 59 (FIG. 1, 2).
  • This end carries a mandrel 38 which is surrounded by a fork of a scraper 39 which slides onto the top surface of the sealing plug 40 during the advancing movement of the rod 35.
  • the stripper 39 is provided with a bevel 41 on its front edge. This ensures in a simple manner that the mandrel 38 always meets the sealing plug 40 during the advancing movement of the rod 35, specifically from the side of the frame. This position is shown in Fig.4.
  • a collecting funnel 46 ' which leads to a discharge chute 47, which is led out of the housing 2 and outside of the housing 4 carries a collecting bag 48 fastened to it, preferably a garbage bag with a cord, for receiving the collected closing plug 40 .
  • a sloping section 49 is provided, by means of which the rod 35 is pressed back into the horizontal position, the locking means 43, for example a ball catch, being disengaged.
  • the housing 2 carries a start button 54 in the form of a illuminated pushbutton on its top wall.
  • the described modular design of the different frames 4 for the different vessel carriers 6 includes for all frames 4 the same design of the bolts 14 and the same arrangement of the electrical coupling 17.
  • the electrical connection can easily be adapted to the respective type of vessel carrier.
  • the step switch 25 (FIG. 4), which ensures that the rack 9 (FIG. 1) moves in the direction of the arrow 55, can of course also be used, with appropriate adaptation, for the gradual movement of the turntable 8 (FIG. 1) in the direction of the arrow 56. Usually, however, a worm gear 58 (FIG. 5) is provided for this.
  • the device In order to absorb the tilting moment which arises when the mandrel 38 is inserted into the sealing plug 40 and thus prevent the sample vessel 7 from being inclined, the device has a spring-loaded pressure pin 57 (FIG. 4) which rests in the lower section of the sample vessel 7 comes and holds the tube in place throughout the stopper removal process.
