Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of feeding equipment, in particular to a reaction container supplementing device. BACKGROUND

[0002] In vitro diagnosis is a widely used diagnostic method in the medical field, which usually uses a reaction cup to collect body fluids, excrements, secretions for chemical composition or chemical reaction analysis to determine the body pathology.

[0003] The existing reaction supplementing device has a small loading volume, and although it can complete the sample detection work, since the reaction cup it contains is limited, the medical staff needs to supplement the reaction cup every interval, which increases the workload and on-duty time of the medical staff, and is inconvenient to use.

[0004] Part of the reaction container supplementing device can directly enter the reaction device along the slide after the reaction cup is discharged from the bottom of the containing cavity, but since it is not transported by jacking, the discharge position is set higher to slide down, and is generally set above the reaction device, which has the problems of large overall volume of the machine and low space utilization rate. Moreover, if the loading capacity of the supplementing device is large, the space occupied will also be more, and it may also cause difficulty in supplementing the reaction cup due to the need to increase the height of the supplementing device.

[0005] Most of the current reaction container devices generally also include a jacking device, and the reaction container is lifted to a certain height by the jacking device after leaving the containing cavity, and then transported or slid down to the designated position.

[0006] Patent applications CN202011574382.0 and CN202011574501.2 disclose a reaction container supplementing device, which is provided with a discharge push block at the bottom of the reaction container containing cavity. The discharge push block pushes the reaction container to a certain height for discharge. The reaction container supplementing device has a small capacity and low space utilization rate. Moreover, since the push block itself has a certain volume, it further reduces the total effective capacity of the containing cavity. In addition, since the push block needs to move frequently in the reaction container, it is also easy to scratch the reaction container and affect the test results. SUMMARY

[0007] In order to solve the above problems, the present application provides a reaction container supplementing device with high effective volume rate, simple structure, low cost, and less prone to jamming.

[0008] The reaction container supplementing device comprises a reaction container accommodating cavity for accommodating at least one reaction container, a discharge port is arranged at the bottom of the reaction container accommodating cavity; a discharge part comprising a conveying plate hinged to the discharge port, a jacking block downstream of the conveying plate, and a transition block downstream of the jacking block; a feeding part comprising a lifting mechanism downstream of the transition block and a chute device downstream of the lifting mechanism; a driving part comprising a first driving mechanism for driving the conveying plate and the jacking block to move, and a second driving mechanism for driving the lifting mechanism to move; wherein the jacking block, the transition block, the lifting mechanism and the chute device are arranged in sequence circumferentially outside the reaction container accommodating cavity.

[0009] The reaction container in the reaction container accommodating cavity is conveyed to the jacking block through the conveying plate at the discharge port, slides to the transition block from the jacking block, reaches the lifting mechanism, is lifted to the entrance of the chute device, and naturally slides along the chute device to the designated position. The components of the reaction container supplementing device are arranged around the reaction container accommodating cavity, the structure is compact, the space utilization rate is effectively improved, and thus the loading capacity of the reaction container accommodating cavity is larger. The conveying plate is hinged at the discharge port of the reaction container accommodating cavity, and the conveying plate is arranged with a certain slope. The material is conveyed along the conveying direction of the conveying plate under the action of gravity. The conveying plate and the jacking block move continuously, and the transportation efficiency is high. In addition, the lifting mechanism is arranged on the circumferential outside of the reaction container accommodating cavity, which is convenient for maintenance, and can also reduce the scratches caused by the collision between the reaction container and the components, and avoid affecting the subsequent detection results.

[0010] Preferably, the downstream end of the conveying plate and the jacking block move up and down reciprocally under the driving of the first driving mechanism, and the downstream end of the conveying plate is not higher than the highest position of the upstream end of the conveying plate when the downstream end of the conveying plate rises to the highest position; the movement direction of the downstream end of the conveying plate and the jacking block is opposite.

[0011] Further, when the downstream end of the conveying plate rises to the highest position, the downstream end of the conveying plate is not lower than the jacking block; and when the jacking block moves to the highest position, the downstream end of the jacking block is not lower than the transition block.

[0012] As can be seen from the above, the movement direction of the downstream end of the conveying plate and the jacking block is opposite, so that the motor does not need to provide a large torque to drive the downstream end of the conveying plate and the jacking block to move simultaneously, thereby reducing the power consumption of the motor and saving cost. In addition, by reasonably arranging the positions of the conveying plate and the jacking block and the up-and-down reciprocating movement distance thereof, the reaction container will not fall back or stack at the discharge port and slide onto the jacking block, so that the transportation of the reaction container to the predetermined direction is ensured. The motor of the first driving mechanism is a motor that can rotate in both forward and reverse directions. When the reaction container is stuck during the transportation process of the conveying plate, the motor can automatically adjust the rotation direction, thereby achieving the purpose of preventing the reaction container from being stuck.

[0013] Further, the first driving mechanism is arranged below the reaction container accommodating cavity, and drives the downstream end of the conveying plate and the jacking block to move up and down simultaneously; the first driving mechanism comprises a first crank assembly, a transmission assembly and a second crank assembly, the transmission assembly drives the first crank assembly and the second crank assembly to move simultaneously, the first crank assembly drives the downstream end of the conveying plate to move up and down, and the second crank assembly drives the jacking block to move in the vertical direction; the transmission assembly comprises a transmission motor, a transmission belt, a first rotating shaft and a second rotating shaft, and the transmission motor drives the first rotating shaft and the second rotating shaft to rotate simultaneously through the transmission belt; the first crank assembly comprises a first conveying connecting rod and a second conveying connecting rod, the two ends of the first conveying connecting rod are hingedly connected with the first rotating shaft and the first end of the second conveying connecting rod respectively, and the second end of the second conveying rod is hingedly connected with the downstream end of the conveying plate; the second crank assembly comprises a first jacking connecting rod and a second jacking connecting rod, the two ends of the first jacking connecting rod are hingedly connected with the second rotating shaft and the first end of the second jacking connecting rod respectively, and the second end of the second jacking connecting rod is hingedly connected with the jacking block; when the first conveying connecting rod is collinear with the second conveying connecting rod, the first jacking connecting rod is not collinear with the second jacking connecting rod.

[0014] As can be seen from the above, when the linkage mechanism is used to drive the downstream end of the conveying plate and the jacking block to move up and down reciprocatingly, the device has fewer components and a more compact structure; when the first conveying connecting rod is collinear with the second conveying connecting rod, the first jacking connecting rod is not collinear with the second jacking connecting rod, which can prevent the connecting rods from being stuck to cause machine failure.

[0015] Further, the ejection part further comprises a jacking slide rail, the jacking block is slidingly connected with the jacking slide rail, and the jacking block slides in the vertical direction on the jacking slide rail.

[0016] Further, the lifting mechanism comprises at least one sample feeding plate and at least one sample receiving plate, and the sample feeding plate and the sample receiving plate are arranged oppositely; the second driving mechanism drives the sample feeding plate to move reciprocatingly periodically in the two butt joint positions; or the second driving mechanism simultaneously drives the sample feeding plate and the sample receiving plate to move reciprocatingly synchronously in the two butt joint positions.

[0017] The lifting mechanism transports the reaction containers by the sample feeding plate and the sample receiving plate moving reciprocatingly synchronously in the oblique direction, and when one reaction cup is moved, the longitudinal movement displacement of the reaction cup is shortened compared with the longitudinal movement displacement when only one reaction cup is moved, space is saved, and the conveying speed of the reaction cup is improved under the condition of the same power.

[0018] Further, the surfaces of the jacking block, the transition block, the sample feeding plate and the sample receiving plate of the lifting mechanism are respectively provided with inclined surfaces inclined to the respective downstream transportation directions.

[0019] Specifically, the jacking block is provided with an inclined surface inclined to the conveying direction of the transition block, the transition block is provided with an inclined surface inclined to the conveying direction of the lifting mechanism, and the sample feeding plate and the sample receiving plate are provided with inclined surfaces inclined to the direction of the chute opening. The arrangement of the inclined surfaces has a guiding effect on the transfer of the reaction container, which helps to improve the conveying efficiency. In addition, by arranging the inclined surfaces on the sample feeding plate and the sample receiving plate, the problem of cup jamming or reaction cup falling caused by the multiple reaction containers standing side by side on the surface can be solved.

[0020] Further, the chute device comprises a chute arranged downwardly, and the chute comprises a chute clamping plate and a connecting fixing member for connecting the chute clamping plate.

[0021] As can be seen from the above, by arranging the chute arranged downwardly, the reaction container can slide to the output opening of the chute groove under the action of its own gravity.

[0022] Further, the chute device further comprises a buffer and / or a protective plate. The buffer comprises a pressing plate hinged above the chute and arranged close to the input opening of the chute. The outer side of the chute clamping plate is provided with a protective plate, and the protective plate is arranged close to the input opening of the chute.

[0023] As can be seen from the above, the protective plate arranged can prevent the reaction container at the input opening from rushing out of the chute groove during the conveying process due to too high speed. The buffer arranged can prevent the reaction container from turning out of the chute due to too large inertia when sliding.

[0024] Further, the chute surrounds the outside of the reaction container accommodating cavity, the chute has at least one bending section, and a corner baffle is arranged on the chute clamping plate outside the bending section.

[0025] As can be seen from the above, the chute is arranged around the outside of the reactor accommodating cavity, which can effectively reduce the overall space occupied by the equipment. The bending section of the chute can effectively reduce the sliding speed of the reaction container and reduce the collision strength between the reaction containers. Further, the corner baffle arranged can prevent the reaction container from sliding out due to too large inertia when turning.

[0026] In summary, the reaction container replenishing device provided by the present application has the advantages of simple structure, compactness, low cost, easy maintenance, etc. The conveying efficiency is high, the accuracy is as high as 99% or more, and the problems of easy jamming, stacking or remaining of similar loading are effectively solved. In addition, the space utilization rate of the reaction container replenishing device is higher, and compared with other reaction container replenishing devices, it can accommodate more reaction containers, which effectively reduces the on-duty time and workload of the staff and improves the detection speed and detection capacity of the medical institutions.

[0045] Reference Figures 1 to 5 The reaction container replenishing equipment provided in the embodiment comprises a storage part 1, a discharge part 2, a feeding part 3 and a driving part 4 arranged in sequence, and the storage part 1, the discharge part 2 and the feeding part 3 are arranged circumferentially around the outside of the storage part 1.

[0046] The storage part 1 has a reactor accommodating cavity 11 capable of accommodating a plurality of reaction containers 19, and the bottom of the reactor accommodating cavity 11 is provided with a discharge port 12, and a plurality of slopes inclined to the discharge port 12 are arranged around the discharge port 12, and each slope has an included angle with the horizontal plane greater than 1° and less than 90°. In the embodiment, the bottom of the reactor accommodating cavity 11 comprises slopes 13a, 13b and 13c; the included angle between the slope 13a and the horizontal plane is 25°, the included angle between the slope 13c and the horizontal plane is 20°, and the included angle between the slope 13b and the horizontal plane is 30°. Under the above-mentioned included angles, the reaction containers 19 in the reactor accommodating cavity 11 slide to the discharge port under the action of gravity, and the number of the reaction containers 19 that can be accommodated is relatively large.

[0047] A mounting seat 14 is mounted on the bottom wall of the reactor accommodating cavity 11, and a conveying plate 15 is hinged to the mounting seat 14, and the conveying plate 15 is arranged obliquely at the discharge port 12, and the surface of the conveying plate 15 is not higher than the discharge port 12, and the conveying plate 15 gradually moves away from the horizontal plane and approaches the discharge port 12 in the direction from the downstream end to the upstream end of the conveying plate 15, and the conveying plate 15 has an included angle with the horizontal plane greater than 1° and less than 90°.

[0048] Preferably, the conveying plate 15 has an included angle of 20° to 30° with the horizontal plane. In operation, the conveying plate 15 is always in a state of inclining to the downstream direction, and the upstream end of the conveying plate 15 is not higher than the discharge port 12.

[0049] Further, baffles (not shown in the figure) are arranged on both sides of the conveying plate 15, and the baffles are used to close the gap formed between the conveying plate 15 and the reactor accommodating cavity 11 when the conveying plate 15 rotates, so as to prevent the reaction containers 19 from separating from the conveying plate 15 from both sides.

[0050] In combination Figures 6 to 11The discharge part 2 comprises a conveying plate 15 hinged to the discharge port 12, a lifting slide rail 16, a lifting block 17 downstream of the conveying plate 15, and a transition block 18 downstream of the lifting block 17. The lifting slide rail 16 extends in the vertical direction, and the lifting block 17 is in sliding connection with the lifting slide rail 16.

[0051] The conveying plate 15 and the lifting block 17 move up and down under the drive of a first driving mechanism 9. The first driving mechanism 9 is arranged below the storage part 1, and comprises a first crank assembly 90, a transmission assembly 91, and a second crank assembly 92. The transmission assembly 91 drives the first crank assembly 90 and the second crank assembly 92 to move simultaneously. The first crank assembly 90 drives the downstream end of the conveying plate 15 to move up and down, and the second crank assembly 92 drives the lifting block 17 to move in the vertical direction along the lifting slide rail 16.

[0052] The transmission assembly 91 comprises a transmission motor 910, a transmission belt 911, a first rotating shaft 912, and a second rotating shaft 913. The transmission motor 910 drives the first rotating shaft 912 and the second rotating shaft 913 to rotate simultaneously through the transmission belt 911. The first crank assembly 90 comprises a first conveying connecting rod 900 and a second conveying connecting rod 901. The two ends of the first conveying connecting rod 900 are hinged to the first rotating shaft 912 and the first end of the second conveying connecting rod 901, respectively. The second end of the second conveying connecting rod 901 is hinged to the downstream end of the conveying plate 15. The second crank assembly 92 comprises a first lifting connecting rod 920 and a second lifting connecting rod 921. The two ends of the first lifting connecting rod 920 are hinged to the second rotating shaft 913 and the first end of the second lifting connecting rod 921, respectively, so as to drive the lifting block 17 to slide on the lifting slide rail 16. The second end of the second lifting connecting rod 921 is hinged to the bottom of the lifting block 17.

[0053] Further, during the movement of the conveying plate 15 and the lifting block 17, the first conveying connecting rod 900 is collinear with the second conveying connecting rod 901, and the first lifting connecting rod 920 is not collinear with the second lifting connecting rod 921. The driving torque of the transmission motor 910 is F, the working torque of the conveying plate 15 is F1, the working torque of the lifting block 17 is F2, the mass of the conveying plate 15 is G1, the mass of the lifting block 17 is G2, the movement direction of the conveying plate 15 is opposite to that of the lifting block 17, the conveying plate 15 moves downward, the lifting block 17 moves upward, and the torque provided by the transmission motor 910 is Fa=F1+F2+G2; when the conveying plate 15 moves upward, the lifting block 17 moves downward, and the torque provided by the transmission motor 910 is Fa=F1+F2+G1. If the first lifting connecting rod 920 and the second lifting connecting rod 921 are 0° coincident, and the first conveying connecting rod 900 and the second conveying connecting rod 901 are 0° coincident, the movement directions of the forces F1 and F2 are the same, the resultant force on the transmission motor 910 is F1+F2, the torque to be provided is the largest, and the connecting rod may be stuck, so the first lifting connecting rod 920 and the second lifting connecting rod 921 and the first conveying connecting rod 900 and the second conveying connecting rod 901 cannot be 0° coincident at the same time.

[0054] During the operation of the equipment, the movement direction of the conveying plate 15 is opposite to that of the lifting block 17, the reaction container is more convenient to transport, the required torque is smaller, and the cost is lower. If the movement direction of the conveying plate 15 is the same as that of the lifting block 17, the torque provided by the transmission motor 910 is Fa'=F1+F2+G1+G2, and Fa<Fa'. In the embodiment, when the first lifting connecting rod 920 and the second lifting connecting rod 921 are 0° coincident, the first conveying connecting rod 900 and the second conveying connecting rod 901 are approximately 180°, the movement directions of the forces F1 and F2 are opposite, the resultant force on the transmission motor 910 is the absolute value of F1-F2, and the torque is the smallest.

[0055] The highest point of the downstream end of the conveying plate 15 is Ha, and the lowest point of the lifting block 17 is Hb. When the downstream end of the conveying plate 15 is driven to rise to the highest position, the downstream end of the conveying plate 15 is not lower than the lifting block 17 (i.e., when Ha>Hb); at this time, the lifting block 17 is located at the lowest position, and the reaction container 19 enters the lifting block 17 from the conveying plate 15. When the lifting block 17 moves to the highest position, the downstream end of the lifting block 17 is not lower than the transition block 18; the reaction container 19 can slide from the lifting block 17 to the transition block 18. In addition, the lowest point of the lifting block 17 will not cause the reaction container 19 to fall from between the lifting block 17 and the transition block 18.

[0056] In combination with Figure 17 and Figure 18 , the minimum width of the cup body of the reaction container 19 is W, the gap between the conveying plate 15 and the lifting block 17 is L, and L

[0057] Further, the jacking block 17 is provided with a jacking slope 170, and the transition block 18 is provided with a transition slope 180, the jacking slope 170 and the transition slope 180 are respectively inclined to the respective downstream direction of transportation, and the jacking slope 170 and the transition slope 180 respectively have an included angle with the horizontal plane greater than 1° and less than 90°. In the embodiment, the included angle of the jacking slope 170 and the transition slope 180 with the horizontal plane is 16°, which has a good guiding effect on the transportation of the reaction container 19.

[0058] The highest point of the transition slope 180 of the transition block 18 has a height of Hc, and the lowest point of the jacking slope 170 of the jacking block 17 has a highest height of Hd during movement; when Hd>Hc, the reaction container 19 can be transported from the jacking block 17 to the transition block 18.

[0059] In combination Figures 12 to 14 , the feeding part 3 includes a lifting mechanism 5 located downstream of the transition block 18 and a chute device 8 located downstream of the lifting mechanism 5.

[0060] The lifting mechanism 5 inclines upward along the lifting direction G to lift the reaction container 19, and the lifting mechanism 5 includes a first lifting assembly 6, a second lifting assembly 7, and a lifting slide rail 50 extending along the lifting direction G, and the first lifting assembly 6 and the second lifting assembly 7 are both in sliding connection with the lifting slide rail 50.

[0061] The second driving mechanism 10 drives the lifting mechanism 5 to move. The second driving mechanism 10 includes a lifting motor 100, a lifting shaft 101, a lifting belt 102, a third crank assembly 103, and a fourth crank assembly 104. The third crank assembly 103 and the fourth crank assembly 104 are respectively hinged at both ends of the lifting shaft 101, and the structures of the third crank assembly 103 and the fourth crank assembly 104 are similar to that of the first crank assembly 90. The first lifting assembly 6 includes a first connecting plate 60 and a plurality of sample feeding plates 61 arranged on the first connecting plate 60; and the second lifting assembly 7 includes a second connecting plate 70 and a plurality of sample receiving plates 71 arranged on the second connecting plate 70.

[0062] The plurality of sample feeding plates 61 and the plurality of sample receiving plates 71 are arranged in alternation. One sample feeding plate 61 and the sample receiving plates 71 adjacent to the upstream side and the downstream side thereof respectively have two butt joint positions. When the sample feeding plate 61 is butt jointed with the sample receiving plate 71 on the upstream side, the sample receiving plate 71 on the upstream side is slightly higher than the sample feeding plate 61, and the reaction container 19 slides from the sample receiving plate 71 to the sample feeding plate 61 on the downstream side; when the sample feeding plate 61 is butt jointed with the sample receiving plate 71 on the downstream side, the sample feeding plate 61 is slightly higher than the sample receiving plate 71 on the downstream side, and the reaction container 19 slides from the sample feeding plate 61 to the sample receiving plate 71 on the downstream side.

[0063] The lifting motor 100 drives the lifting shaft 101 to rotate through the lifting belt 102, drives the third crank assembly 103 and the fourth crank assembly 104 to move, thereby driving the first connecting plate 60 and the second connecting plate 70 to slide on the lifting slide rail 50, thereby driving the driving sample plate 61 and the sample plate 71 fixedly connected thereto to synchronously and periodically reciprocate in two butt joint positions, thereby lifting the reaction container 19 upward.

[0064] The movement direction G of the first connecting plate 60 and the first horizontal direction F are provided with an included angle γ, the movement direction G of the second connecting plate 70 and the first horizontal direction F are provided with an included angle δ, 0°<γ<90°, 0°<δ<90, and the angles γ and δ are equal. The first connecting plate 60 and the second connecting plate 70 are parallel to each other, and the movement directions of the first connecting plate 60 and the second connecting plate 70 are opposite. The setting of the included angle γ and the included angle δ can make the reaction container 19 smoothly transport in the set direction, and effectively avoid the reaction container 19 from falling during the transportation process, thereby increasing the transportation efficiency.

[0065] In order to effectively transport the reaction container 19 in the conveying direction, the width of the sample plate 61 and the sample plate 71 is greater than 1 / 2 of the maximum width of the reaction container 19, and the reaction container 19 is not easy to slide off during the transportation process.

[0066] Further, the sample plate 61 has a sample inclined surface 610 on the upper surface, and the sample plate 71 has a sample inclined surface 710 on the upper surface. The sample inclined surface 610 and the sample inclined surface 710 are inclined to the downstream direction of the transportation, and form an included angle α, β with the second horizontal direction E, 0°<α, β<90°, and the angles α and β are equal. The inclined surface on the sample plate 61 or the sample plate 71 adjacent to the entrance of the slide 80 is inclined to the direction of the slide 80, and the inclined surfaces on the rest of the sample plate 61 and the sample plate 71 are parallel to the same. It is found during the test that if the surface of the sample plate 61 and the sample plate 71 is parallel to the horizontal plane, when the reaction container 19 is transported along the movement direction, multiple reaction containers 19 will stand vertically on the surface of the sample plate 61 or the sample plate 71, and the reaction container 19 is easy to fall off during the transportation process, or after reaching the end of the lifting mechanism, multiple reaction containers 19 are stuck on the plate and cannot enter the chute. By setting the surface of the sample plate 61 and the sample plate 71 as an inclined surface, the problem is well overcome, and the transportation efficiency is greatly improved.

[0067] In combination with Figure 15 and Figure 16 , the chute device 8 includes a slide 80, a vibration motor 81, two protective plates 82, a corner baffle 83 and a buffer 84, the input port of the slide 80 is adjacent to the output port of the lifting mechanism 5,

[0068] The chute 80 is arranged downwardly inclined, and the chute 80 comprises a connecting fixing 800 and two oppositely arranged chute clamping plates 801 connected by the connecting fixing 800, and a hollow chute 802 is formed between the two chute clamping plates 801, the width of the chute 802 is greater than the diameter of the smallest outer wall of the reaction container 19 and less than the diameter width of the cup edge of the reaction container 19. The lifting mechanism 5 lifts the reaction container 19 to the highest position, and the reaction container 19 automatically slides onto the chute 80 due to its own gravity, and the reaction container 19 can be correctly overturned due to its own balance point after entering the chute 802, so that the mouth of the reaction container 19 faces upward.

[0069] The chute 80 surrounds the outside of the storage part 1, and the chute 80 has two bending sections 803. The multi-section design can be matched with storage parts 1 of different shapes, reducing the overall space occupied; in addition, the turning of the bending section 803 can reduce the speed of the reaction container 19 sliding down, on the one hand to avoid the reaction container 19 sliding out, and on the other hand to reduce the collision strength between the reaction containers 19. The chute 80 comprises a first chute slope 804, a second chute slope 805 and a third chute slope 806 connected in turn along the conveying direction, one bending section 803 is located between the first chute slope 804 and the second chute slope 805, and the other bending section 803 is located between the second chute slope 805 and the third chute slope 806. Optionally, the included angle between any one of the first chute slope 804, the second chute slope 805 and the third chute slope 806 and the horizontal plane is between 20° and 90°. In the embodiment, the included angle between the first chute slope 804 and the horizontal plane is 25°, the included angle between the second chute slope 805 and the horizontal plane is 27°, and the included angle between the third chute slope 806 and the horizontal plane is 22°.

[0070] The protective plates 82 are arranged on the two chute clamping plates 801 respectively and close to the input port of the chute 80. The buffer 84 is a tablet, the tablet is hinged between the two protective plates 82, and the tablet is arranged above the chute 80 and close to the input port of the chute 80. The chute clamping plate 801 outside the bending section 803 at the upstream end of the chute 80 is provided with a corner baffle 83.

[0071] The reaction containers 19 reach the end of the chute 80 in turn and wait to enter the next component (basically at the same horizontal plane as the end), and may be stationary at the end of the chute 80 due to friction and other factors when needed to enter the next component. The vibration motor 81 can disturb the reaction containers 19 to make them slide to the next component, thereby preventing material from being stuck.

[0072] Preferably, the reaction container 19 supplement device is also provided with a sensing device (not shown in the figure) for monitoring the loading amount of the reaction container 19 on the lifting mechanism 5 and the chute device 8. The sensing device can use existing photoelectric sensors and the like. When the number of reaction containers 19 in the chute device 8 or the lifting mechanism 5 exceeds the set peak value, the driving part 4 automatically stops operating; when the number of reaction containers 19 in the chute device 8 or the lifting mechanism 5 is lower than the set median value, the driving part 4 automatically resumes operating; when the number of reaction containers 19 in the chute device 8 or the lifting mechanism 5 reaches the set valley value, the driving part 4 automatically stops operating and prompts the staff to supplement the reaction container 19 or check whether the machine has a problem.

[0073] It should be noted that the above is only the preferred embodiment of the present application, but the design concept of the application is not limited thereto, and any non-essential modification of the application made by using this concept also falls within the protection scope of the application.
