Description

Technical Field

[0001] The invention belongs to the field of medical auxiliary equipment, and in particular relates to a crank that automatically lifts a material box. Background Art

[0002] Automatic feeding has been used earlier and more widely in industry. For example, the push plate lift is a device that lifts materials by pushing the plate. It uses mechanical, hydraulic or electric power sources to push the push plate to reciprocate, thereby pushing the material from a low place to a high place. In the use of the push plate lift, such as the screw processing process, the feeding device may occasionally have one or two screws left in the feeding box, stay on the lifting plate surface, or get stuck between the lifting plates. These effects can be ignored in the screw processing process. Therefore, these factors do not affect its wide application.

[0003] However, automatic feeding is rarely used in the medical testing industry. Each clinical specimen corresponds to the patient's diagnostic needs and corresponding medical responsibilities, and requires that the first specimen to arrive be tested first, and that the specimen cannot be left in the feeding box, etc., so as not to cause specimens to be missed or tested overtime. Therefore, in the medical testing industry, it will require more precise operational requirements.

[0004] In the prior art, the one-way push-up connecting rod feeding device faces many problems. The main problems are: first, the test tube slides from the first push plate to the other push plate by its own gravity, and it is easy to stay on the lifting plate surface. Second, there is a set of dynamic push plates and a set of static baffles, so the test tube may be stuck on the static baffle. Third, the one-way push plate structure has a dilemma that if one push plate is too thick, the test tube is not easy to slide to the other push plate, and if the push plate is too thin, it is easy to fall during the push-up process, causing blood vessel damage. Fourth, the one-way push plate structure is long, heavy, and the push plate has a long movement stroke. The test tube is easy to slide, and the motor power is large, the noise is high, and other problems. Fifth, with the increasing number of hospital test specimens, even some large hospitals or medical centers sort tens of thousands of specimens in 1 hour. If only by increasing the number of sorting machines, the cost will increase greatly, and it is difficult to meet the process connection. Therefore, the required silos are getting bigger and bigger; the larger the silo, the longer the lifting plate stroke is required, and the lifting requirements are becoming more and more stringent. The lifting scheme of the prior art is difficult to expand. Summary of the invention

[0005] The purpose of the present invention is to provide a crank-automatic lifting material box. By dividing the lifting plate into fine parts and using a driving motor to control the crank structure to control the lifting plate to push the material step by step, all blood collection tubes can be sorted until they are transported to the next level detection platform.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is specifically as follows: A crank automatically lifts a material box, comprising a casing, a hopper arranged in the casing, a driving assembly and a lifting assembly, wherein a transmission assembly is arranged between the lifting assembly and the driving assembly; The lifting assembly includes at least two groups of lifting plate assemblies, and the top of each group of lifting plate assemblies is staggered in height in the hopper, and the bottom of each group of lifting plate assemblies is respectively connected to adjacent lifting beams; The transmission assembly includes a crank lifting mechanism and a reversing crank mechanism, the crank lifting mechanism includes an eccentric wheel and a crank connecting rod, and the eccentric wheel is connected to the driving assembly, and the two ends of the crank connecting rod are respectively connected to the lowest lifting beam; the reversing crank mechanism includes a reversing inverted rod, a first linkage sub-rod and a second linkage sub-rod symmetrically connected to the reversing inverted rod, and the first linkage sub-rod and the second linkage sub-rod are respectively connected to the lifting beams located at two adjacent groups of lifting plates.

[0007] Furthermore, the driving assembly includes a driving motor and a reducer connected to an output shaft of the driving motor, and the reducer is connected to the eccentric wheel via a rotating shaft.

[0008] Furthermore, the lifting assembly also includes a guiding mechanism, which includes vertical slide rails fixed on both sides of the casing, and a plurality of sliding blocks are arranged on the vertical slide rails.

[0009] Furthermore, a transverse fixed support plate is provided in the middle of the vertical slide rail, and the transverse fixed support plate is connected to the side wall of the casing.

[0010] Furthermore, each lifting beam is respectively connected between two sliding blocks and moves up and down along the vertical sliding rail.

[0011] Furthermore, each group of the lifting plate assemblies includes two lifting plates arranged at different heights, and the lifting plates of the two groups of lifting plate assemblies are arranged alternately.

[0012] Furthermore, the highest stroke position of the low-positioned lifting plate is flush with the lowest stroke position of the adjacent pusher.

[0013] Furthermore, the lifting plate assembly also includes a linkage mechanism, and the linkage includes a connecting back plate, and the connecting back plate is respectively connected to the lifting plates at different heights.

[0014] Furthermore, the connecting back plate is L-shaped, including a vertical long plate and a horizontal short plate, and is connected to the lifting beam through the horizontal short plate.

[0015] Furthermore, the hopper is arranged on the top of the casing and is provided with an inclined feeding plate, and the inclined feeding plate is connected to the top of the lowest lifting plate.

[0016] Compared with the prior art, the advantages of the present invention are: first, the present invention adopts an automated control method to collect the collected blood collection tubes into a hopper respectively, and the hopper is provided with an inclined feeding plate, and the blood collection tubes are accumulated at the bottom of the hopper under the action of gravity; and through the control method of the crank connecting rod, the alternating up and down reciprocating motion of at least two groups of lifting plates is realized, so that the blood collection tubes can be lifted step by step from the hopper until they are lifted from the bottom of the hopper to the top of the lifting plate.

[0017] Secondly, the two sets of different lifting plates reciprocate in opposite directions. When the test tube slides from the first push plate to the other push plate, the downward moving push plate has downward friction, which makes it difficult for the test tube to be retained. It can basically ensure that the test tube is not retained. At the same time, the thickness of the plate surface at the end of the push plate can be increased to prevent the test tube from falling. In this way, the demand for first-come-first-test of specimens in the medical testing industry can be met, and missed inspections and delayed inspections can be prevented, so that automatic feeding can be truly widely used in this industry.

[0018] Secondly, in the present invention, the length of a single push plate can be effectively reduced, and the instrument structure used is simple, and a low-power motor can be selected to reduce costs and reduce noise. During operation, the movement stroke of a single push plate is reduced, and the step-by-step transfer of test tubes and the efficiency are improved.

[0019] Thirdly, the present invention has strong scalability. As the number of specimens in the hospital increases, the number of crank lifting mechanisms, reversing crank mechanisms and lifting plate groups can be increased accordingly in the future, thereby meeting the needs of higher-altitude lifting, sorting and transportation of more specimens.

[0033] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0034] like Figure 1-Figure 5 As shown, a crank automatically lifts a material box, comprising a housing 13, a hopper 14 arranged in the housing 13, a driving assembly and a lifting assembly, and a transmission assembly is arranged between the lifting assembly and the driving assembly; The lifting assembly includes at least two groups of lifting plate assemblies 11, and the top of each group of lifting plate assemblies 11 is staggered in height in the hopper 14, and the bottom of each group of lifting plate assemblies 11 is respectively connected to adjacent lifting beams; The transmission assembly includes a crank lifting mechanism and a reversing crank mechanism, the crank lifting mechanism includes an eccentric wheel 3 and a crank connecting rod 4, and the eccentric wheel 3 is connected to the driving assembly, and the two ends of the crank connecting rod 4 are respectively connected to the lowest lifting beam; the reversing crank mechanism includes a reversing inverted rod 5, a first linkage sub-rod 6 and a second linkage sub-rod 8 symmetrically connected to the reversing inverted rod 5, and the first linkage sub-rod 6 and the second linkage sub-rod 8 are respectively connected to the lifting beams located at two adjacent groups of lifting plates.

[0035] Different from the prior art, in the present invention, a crank structure is used to drive the crank lifting assembly under the drive motor 1, which drives the lifting beam at the bottom to lift or lower during the rotation cycle of the eccentric wheel 3. One of the linkage sub-rods of the reversing crank mechanism is also connected to the lifting beam at the bottom, thereby driving the reversing inverted rod 5 to rotate, and then driving the crank arm on the other side of the reversing inverted rod 5 to drive the lifting beam at the high position to reciprocate up and down. The lifting beams at the high and low positions are alternately reciprocated by two sets of lifting plate assemblies 11, so that the blood collection tubes accumulated at the lowest point of the hopper 14 are lifted in an orderly manner to the top of the hopper 14 in sequence; by analogy, adding a set of crank lifting mechanisms and reversing crank mechanisms can extend the coordinated movement of a set of lifting plates in opposite directions.

[0036] The driving assembly includes a driving motor 1, a reducer 2 connected to the output shaft of the driving motor 1, and the reducer 2 is connected to the eccentric wheel 3 through a rotating shaft. The driving motor 1 is output adjusted by the reducer 2 and the output shaft of the reducer 2 is connected to the eccentric wheel 3, and the eccentric wheel 3 is controlled to rotate.

[0037] The lifting assembly also includes a guide mechanism, which includes vertical slide rails 12 fixed on both sides of the housing 13, and a plurality of sliders 10 are arranged on the vertical slide rails 12. A transverse fixed support plate 15 is arranged in the middle of the vertical slide rail 12, and the transverse fixed support plate 15 is connected to the side wall of the housing 13. Each lifting beam is connected between two sliders 10 and moves up and down along the vertical slide rail 12. The movable direction of the lifting beam is limited and constrained by setting the guide mechanism.

[0038] Each group of the lifting plate assembly 11 includes two lifting plates arranged at different heights, and the lifting plates of the two groups of lifting plate assemblies 11 are arranged alternately. The highest stroke position of the lifting plate arranged at a low position is flush with the lowest stroke position of the adjacent pusher. The lifting plate assembly 11 also includes a linkage mechanism, and the linkage includes a connecting back plate 16, which is respectively connected to the lifting plates at different heights. The connecting back plate 16 is L-shaped, including a vertical long plate and a horizontal short plate, and is connected to the lifting beam through the horizontal short plate.

[0039] The hopper 14 is arranged on the top of the casing 13 and is provided with an inclined feeding plate, and the inclined feeding plate is connected to the top of the lowest lifting plate.

[0040] Implementation Method 1 In actual use, Figure 1-Figure 3 As shown, the present invention specifically sets two groups of lifting plate assemblies 11, and each group of lifting plate assemblies 11 includes two lifting plates respectively. The two groups of lifting plate assemblies 11 have a total of four lifting plates, which are respectively recorded as the first lifting plate, the second lifting plate, the third lifting plate and the fourth lifting plate, and the first lifting plate to the fourth lifting plate are arranged in order, and the first lifting plate and the third lifting plate are a group, and the second lifting plate and the fourth lifting plate are a group, forming a staggered arrangement. A total of two lifting beams are set, which are respectively recorded as low-position lifting beams 7 and high-position lifting beams 9, wherein the low-position lifting beam 7 is respectively linked with the first lifting plate and the third lifting plate by connecting the back plate 16, and the low-position lifting beam 7 is respectively connected with a crank connecting rod 4 and a first linkage auxiliary rod 6. Similarly, the high-position lifting beam 9 is respectively linked with the second lifting plate and the fourth lifting plate by connecting the back plate 16, and the high-position lifting beam 9 is connected to the second linkage auxiliary rod 8.

[0041] When working, the collected blood collection tubes are put into the hopper 14, and the blood collection tubes slide down to the bottom of the hopper 14 along the inclined plate of the hopper 14 under the action of their own weight. When the first lifting plate is at the lowest point of the stroke, its top will be at the bottom of the hopper 14. When the fourth lifting plate is at the highest point of the stroke, its top will be higher than the top of the hopper 14.

[0042] The driving force is provided by the driving motor 1 and output to the crank lifting mechanism after adjustment by the reducer 2. The eccentric wheel 3 of the crank lifting mechanism reciprocates around the output shaft. The crank connecting rod 4 connected to the eccentric wheel 3 will rise and fall with the rotation position of the eccentric wheel 3. Then, the crank connecting rod 4 pushes the low-position lifting beam 7 upward or pulls the low-position lifting beam 7 downward, and the first lifting plate and the third lifting plate will move upward or downward in this process.

[0043] The reversing crank mechanism is respectively provided with a first linkage sub-rod 6 and a second linkage sub-rod 8, wherein the second linkage sub-rod 8 is connected to the high-position lifting beam 9, and the first linkage sub-rod 6 is connected to the low-position lifting beam 7. When the low-position lifting beam 7 is lifted or lowered, the first linkage sub-rod 6 will act as a follower to push up or pull down respectively. Correspondingly, the reversing inverted rod 5 will rotate accordingly, and the second linkage sub-rod 8 will act as a follower with the rotation of the crank flywheel, and finally drive the high-position lifting beam 9 to lift or lower. It should be noted that because the first linkage sub-rod 6 and the second linkage sub-rod 8 are respectively arranged on both sides of the reversing inverted rod 5, the movement directions of the first linkage sub-rod 6 and the second linkage sub-rod 8 are opposite. Therefore, when the first lifting plate and the third lifting plate are lifted, the second lifting plate and the fourth lifting plate will fall, and vice versa.

[0044] When the first lifting plate is at the highest lifting stroke, the second lifting plate is at the lowest descending stroke. At this time, the first lifting plate and the second lifting plate are in a flush state. When setting, the lifting plates are slightly inclined and slightly high. The blood collection tube will roll from the first lifting plate to the top of the second lifting plate under the weight and the downward friction of the second push plate. After the blood collection tube reaches the second lifting plate, the second lifting plate will change from the descending state to the lifting state until it reaches the maximum lifting stroke. Similarly, it will be transferred to the third lifting plate, and the third lifting plate will be transferred back to the fourth lifting plate, and finally the fourth lifting plate will push it to the next conveying station.

[0045] In the whole process, the present invention adopts an automated control method to collect the collected blood collection tubes into the hopper 14, and the hopper 14 is provided with an inclined feeding plate, and the blood collection tubes are accumulated at the bottom of the hopper 14 under the action of gravity; and through the control method of the crank connecting rod 4, the reciprocating motion of the two sets of lifting plates is realized, so that the blood collection tubes can be lifted step by step from the hopper 14 until the blood collection tubes are lifted from the bottom of the hopper 14 to the top of the lifting plate. Through the reciprocating motion of the two sets of different lifting plates in opposite directions, in the process of the test tube sliding from the first push plate to the other push plate, the downwardly moving push plate has a downward friction force, so that the test tube is not easy to be retained, which can basically ensure that the test tube is not retained, and at the same time, the plate thickness at the end of the push plate can be increased to prevent the test tube from falling, so that the requirements of the first-come-first-test of specimens in the medical testing industry can be met, and the occurrence of missed inspections and delayed inspections can be prevented, so that automatic feeding can be truly widely used in this industry.

[0046] Implementation Method 2 The present invention can be further modified and expanded on the basis of the first embodiment, for example, the number of lifting plate assemblies 11 can be increased. Similarly, the reversing crank mechanism controlling the linkage should also be increased, so that each group of lifting plate assemblies 11 can be driven by the crank lifting mechanism.

[0047] On the one hand, it can effectively reduce the length of a single push plate while keeping the lifting height unchanged. For example, when the lifting height of the lifting scheme is 1 meter, for the traditional one-way push plate structure, the first push plate needs to be more than 1M long, and it also needs to be matched with a corresponding static baffle, which is very large in size and has the aforementioned dilemma. It is obviously not practical. In the present invention, the lifting plate can be easily implemented by splitting it into multiple groups. On the other hand, by splitting the length of a single push plate, the maximum height that can be lifted by the present invention can be further improved compared with the prior art. The overall scalability is strong. Under extreme demands, the number of groups of push plates and reversing crank structures can be increased accordingly, which can meet the requirements of higher height lifting, sorting and transmission under specific conditions. Moreover, during the movement, the movement stroke of a single push plate is reduced, and the efficiency of step-by-step transfer and lifting of test tubes is improved. The instrument structure is simple, so a low-power motor can be selected to reduce costs and reduce noise.

[0048] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
