With the improvement of the automation degree, various automatic machines are widely used for effectively managing the test tubes, so that the efficiency is greatly improved, and errors caused by manual operation are avoided.
The labeling machine is an automatic instrument which prints the information and the number of a testee and automatically and orderly pastes the information and the number to the corresponding test tube. In such instruments, it is important to efficiently and orderly manage the test tubes to sequentially enter the labeling assembly for labeling in a prescribed manner.
Various solutions for dispensing test tubes have been disclosed in the prior art. For example, CN101149386A discloses a sample pretreatment/delivery apparatus, which comprises: a test tube transfer passage on which test tubes filled with samples are individually held in the test tube holders, respectively, and transferred in a standing position one by one; a rack conveyance path that extends parallel to the test tube conveyance path, on which each set of at least 5 cuvettes is held in a standing position in a cuvette holder, and which is conveyed; a filled test tube loading section that loads a test tube filled with a sample into the test tube transfer path; a rack loading section that loads the specimen cup rack into the rack conveyance path; an aliquoting/dispensing device, located in the middle of the test tube transport path, configured to simultaneously aliquote samples from each set of at least 5 sample-filled test tubes transported on the test tube transport path and simultaneously dispense them into at least 5 sample cups on the rack transport path; and an analyzer, located on a downstream side of the rack transport path, configured to receive the specimen cup rack storing the specimen and analyze the specimen.

Detailed Description
Other objects and advantages of the present invention will become apparent from the following explanation of the preferred embodiments of the present application.
The tube dropping device is a device for managing test tubes to be taken out or entered into a subsequent mechanism individually and sequentially or simultaneously according to the specified requirements. Preferably, the drop tube device refers to a device for labelling machines. More preferably, the tube dropping device of the present invention refers to a device for managing test tubes for orderly application of desired labels.
In a first aspect of the present invention, a tube dropping device is provided, which comprises a slide inclined plate, an electromagnet fixing plate, a stop lever supporting plate and a test tube control assembly. Optionally, a sensor is further included. The components are described in detail below.
[ inclined plate of slide track ]
The slide way sloping plate is of a plate-shaped structure which is obliquely arranged at a certain angle. A slide allowing the test tube to slide down along a predetermined track, for example, in a vertically suspended manner is provided on the slide inclination plate. The width of the slide is not particularly limited as long as it allows a portion (e.g., a body) of the test tube to freely pass through and slide down. Preferably, the width of the slide is 1.01 to 1.5 times, more preferably 1.05 to 1.2 times the diameter of the test tube. In addition, the length of the slide is not particularly limited, and is generally sufficient to ensure that 4 to 30 test tubes are arranged simultaneously, preferably 6 to 15 test tubes are arranged simultaneously, and more preferably 8 to 10 test tubes are arranged simultaneously. The number of the ramps in the ramp plate of the present invention is not particularly limited, and may be arbitrarily set as required, for example, 1 ramp, but usually the number of the ramps is plural, for example, 2 to 40, preferably 4 to 20, and more preferably 6 to 10. The number of slides in this range is advantageous to ensure efficient dispensing of the test tubes, and does not make the device bulky.
In the present invention, the vertical suspension comprises the provision of specific members on the test tube for suspending the test tube on the slide. Preferably, the test tube is suspended by means of a cap structure, such as a test tube, in contact with the slide, which is a simple design, which is advantageous for cost reduction.
In the present invention, it is preferable that the test tube slides down the slide way only by gravity without external force. Therefore, the slide inclination plate needs to maintain an inclination angle sufficient to allow the test tube to slide down by gravity. Preferably, the ramp does not have a bottom plate that can contact the bottom of the test tube, facilitating the free sliding down of the test tube. In certain embodiments, the lower portion of the slide has an opening to allow the sliding test tube to freely fall into the prescribed mechanism in a vertical manner. In some embodiments, the lower portion of the slide is provided with a blocking member to prevent the test tube from being excessively far away from the tube dropping device after sliding down.
[ test tube control Assembly ]
The test tube control assembly is used for controlling the distribution of test tubes in a single slide way and comprises a three-edge lever, a first stop lever, a second stop lever, an electromagnet mandrel and an electromagnet.
The three-sided lever of the present invention includes a first fulcrum, a second fulcrum, a third fulcrum, and a central through hole. The three-sided lever may have a shape of "T" or "Y", which is not particularly limited as long as it has three fulcrums by rotating around a central through hole. The "center" in the present invention is a relative concept and does not refer to the absolute center position of the three-sided lever. In certain embodiments, the three-sided lever includes a first "T" shaped tab, a second "T" shaped tab, a first fulcrum shaft, a second fulcrum shaft, a third fulcrum shaft, and a central through-hole shaft, and the first fulcrum shaft, the second fulcrum shaft, the third fulcrum shaft, and the central through-hole shaft are located between the first "T" shaped tab and the second "T" shaped tab, respectively. In certain embodiments, the three-sided lever is integrally formed and a central through hole is provided in the integrally formed three-sided lever. The design can be conveniently used for a plurality of three-edge levers to parallelly share the same horizontal shaft.
The shape of the first stopper and the second stopper of the present invention is not particularly limited, and may be a cylindrical rod (i.e., a stopper), a flat plate (i.e., a stopper), or an irregular shape. The material of the first stopper and the second stopper is not particularly limited, and may be a hard plastic or a metal material. The blocking of the first blocking element and the second blocking element may be performed in the same manner or in different manners. In some embodiments, the first stop blocks the sliding down of the test tube by being located in front of the test tube. In certain embodiments, the second stop blocks the tube from sliding down by inserting its end into a groove, for example, inside the tube or on the top of the cap.
The electromagnet mandrel of the present invention is made of a magnetically attractable material such as metallic iron or the like. The electromagnet mandrel may be cylindrical in shape. Preferably, the electromagnet core shaft includes an exposed portion for connecting the end of the electromagnet core shaft connected to the third fulcrum with the contact portion, and the contact portion is movable inside the electromagnet.
The electromagnet of the invention is non-permanent magnetism, and has magnetism when being electrified and loses magnetism when being electrified. The shape of the electromagnet is not particularly limited, and it is preferable that an internal cavity matching the contact portion of the electromagnet spindle is provided inside the electromagnet. More preferably, the length of the internal cavity is greater than the length of the contact portion.
In the case that the tube dropping device comprises a plurality of groups of test tube control assemblies, preferably, the tube dropping device comprises an equal number of electromagnets, and the electromagnet mandrel in each group of test tube control assemblies is arranged corresponding to a single electromagnet. In certain embodiments, in the initial state, the exposed portion of the electromagnet mandrel is spaced from the electromagnet and a portion (e.g., the free end) of the electromagnet mandrel is free to move within the internal cavity of the electromagnet. When energized, the electromagnet mandrel moves the exposed portion closer to the electromagnet due to magnetic attraction. When the power is lost, the magnetism of the electromagnet disappears, and the electromagnet mandrel returns to the original position. The electromagnet mandrel may restore its original position by its own weight or by elastic means (e.g., a spring, a pressing piece, a rubber band, etc.). In certain embodiments, the resilient means is disposed between the electromagnet and the electromagnet mandrel. In certain embodiments, the resilient means is a spring and is located in the internal cavity of the electromagnet.
In the invention, one end of the first blocking piece is rotatably connected to the first fulcrum, one end of the second blocking piece is rotatably connected to the second fulcrum, one end of the electromagnet mandrel is rotatably connected to the third fulcrum, and the three-edge lever is fixed above the blocking piece supporting plate through a horizontal shaft penetrating through the central through hole and a fixed column. In certain embodiments, the plurality of three-sided levers share a common horizontal axis and are secured to the stop support plate by a horizontal axis passing through the central through hole and two fixing posts located at both ends of the horizontal axis. In certain embodiments, each three-sided lever is secured to the step support plate by a horizontal shaft and a fixed post.
In the case where the tube dropping device of the present invention includes a plurality of sets of test tube control assemblies, the number of the test tube control assemblies is the same as the number of the slide ways, so that each set of test tube control assemblies is disposed below each slide way in a manner corresponding to one slide way, respectively. For example, in the condition that the slide swash plate includes first slide, the second slide, the third slide, the fourth slide, the fifth slide, the sixth slide, seventh slide and eighth slide, and the tube falling device includes first test tube control assembly, second test tube control assembly, third test tube control assembly, fourth test tube control assembly, fifth test tube control assembly, sixth test tube control assembly, seventh test tube control assembly and eighth test tube control assembly, first test tube control assembly corresponds to first slide setting, second test tube control assembly corresponds to second slide setting, third test tube control assembly corresponds to third slide setting, analogize in proper order. In certain embodiments, multiple sets of tube control assemblies share the same horizontal axis and share a pair of fixed posts, thereby securing the multiple sets of tube control assemblies above the stop support plate. Namely, a plurality of trilateral levers of the multi-group test tube control assembly are arranged side by side, the horizontal shaft penetrates through central through holes of the trilateral levers, and two ends of the horizontal shaft are fixed on the blocking piece supporting plate through two fixing columns. The fixing post has a height sufficient to enable the three-sided lever to rotate at least 5 degrees, preferably 10 degrees, more preferably 20 degrees.
[ electromagnet fixing plate ]
The electromagnet fixing plate is used for fixing the electromagnet. The electromagnet fixing plate is fixed above the slide way sloping plate, preferably above the slide way sloping plate in a mode of being perpendicular to the blocking piece supporting plate. The length of the electromagnet fixing plate preferably spans the width of the slide ramp. The height of the electromagnet fixing plate is preferably larger than the diameter of the third through hole. The electromagnet fixing plate can also be provided with a third through hole which is used for supporting one end of the electromagnet mandrel and enabling the electromagnet mandrel to move along the direction of the third through hole. The number of third through holes is preferably the same as the number of slides or the number of cuvette control assemblies. Preferably, the third through hole is provided in such a manner that the electromagnet passes through the third through hole. It is also preferable that an electromagnet is fixed on the other side of the third through hole. The electromagnet may be arranged so that the two sides of the electromagnet fixing plate in the thickness direction are not communicated. Therefore, in a specific case, the third through hole may be a groove that allows the end of the electromagnet core shaft to be inserted into a portion in the thickness direction of the electromagnet fixing plate, rather than a hole that actually penetrates therethrough.
In some embodiments, the electromagnet fixing plate is fixed above the slide swash plate by a first side plate on one side of the slide swash plate and optionally a second side plate on the other side of the slide swash plate. The minimum distance between the electromagnet fixing plate and the inclined plate of the slide way is required to allow the test tube to pass through, and the minimum distance is not particularly limited.
[ blocking piece supporting plate ]
The shelves piece backup pad is fixed in the top of slide swash plate, and it is used for supporting first shelves piece, second shelves piece and supports test tube control assembly. The minimum distance between the baffle support plate and the inclined plate of the slide way is enough to allow the test tube to pass through. Preferably, the stop support plate is disposed above the ramp plate in a horizontal direction, and a minimum distance from the ramp plate is about 0.5 to 5cm, preferably 1 to 3cm, above the stop support plate.
The blocking piece supporting plate comprises a first through hole and a second through hole, the first through hole allows a part of the first blocking piece to freely pass through, and the second through hole allows a part of the second blocking piece to freely pass through. In a preferred arrangement, the first through hole is provided with a first channel to allow a portion of the first stop to move freely therein, and the second through hole is provided with a second channel to allow a portion of the second stop to move freely therein. The length of the first and second channels is greater than the thickness of the stop support, preferably 2-20 times, more preferably 3-10 times the thickness of the stop support. In another aspect, the length of the first channel is less than the length of the first stop, and the length of the second channel is less than the length of the second stop. The arrangement of the first and second channels facilitates guiding the first and second stop members to move freely in a prescribed direction.
The stop support plate of the present invention preferably further comprises a fixing post fixing location for fixedly attaching the fixing post to the stop support plate. The number of the fixing posts can be multiple. In some embodiments, the two fixing posts are respectively located at two sides of the stopper supporting plate. In some embodiments, the number of the fixing column fixing positions is the same as the number of the test tube control assemblies or the number of the slide ways.
