Description

Technical Field

[0001] The present invention mainly relates to the field of sample analysis instruments, and particularly relates to a rotary bottle arranging machine for material sampling, preparation and analysis. Background Art

[0002] For the chemical analysis work of material (such as ore, coal) samples, each country has mandatory standards that must be followed. Taking the chemical analysis of coal samples as an example, the criterion for the chemical analysis work process of samples is to conduct relevant chemical analysis on qualified samples without destroying the representativeness of the samples. In this process, it is required to ensure the accuracy of chemical analysis as much as possible so that the chemical analysis results can most truly reflect the characteristics of the samples.

[0003] At present, an automatic sample preparation system has replaced manual sample preparation. The automatic sample preparation system automatically prepares samples such as full water samples, storage samples, and analysis samples according to the original coal sample through processes such as crushing, reduction, drying, and powder making. This system generally includes primary crushing, primary reduction, secondary crushing and reduction, drying and powder making reduction, etc. The primary reduction will produce full water samples, the secondary crushing and reduction will produce storage samples, and the drying and powder making reduction will produce analysis samples. The full water samples, storage samples, and analysis samples produced by the automatic sample preparation system all need to be placed in sample bottles for sample receiving operations. Since the sizes and heights of the sample bottles are also different, it is also necessary to distinguish and arrange these sample bottles with different quantities and loaded samples to facilitate the subsequent development of automatic sample preparation operations.

[0004] In the prior art, such as patent CN215478125U, it relates to a bottle feeding device for a sample preparation system. This mechanism adopts a belt conveying mode. The belt and the flow channel are fixed on the frame, and there is a gap between the belt and the flow channel. The sample bottles are conveyed by the movement of the belt, and at the same time, the flow channel locates the movement track of the sample bottles. There are 4 flow channels in this scheme, that is, 4 bottle placing openings, and then the sample bottles are manually selected and placed into the flow channels. In this bottle arranging scheme, the sample bottles are conveyed by the belt to the waiting position, and the position of the sample bottles is limited by the limit plate, and the limit plate is installed on the rotary cylinder, and the cylinder controls the rotation of the limit plate; when the rotary cylinder controls the limit plate to rotate 90 degrees to be parallel to the flow channel, the sample bottles are no longer restricted, and the sample bottles reach the handling position under the conveying of the belt. At this time, the translation cylinder controls the push plate to push the sample bottles into the next process to complete the handling work. There are the following technical problems:

[0005] First, the belt conveying mode has high costs; the design of the belt and the flow channel occupies a large space, resulting in waste of overall resources.

[0006] Second, the upright sample bottles move horizontally through the friction force with the belt. When the belt speed is relatively fast, the sample bottles may slip, resulting in bottle overturning, which affects the development of automated operations.

[0007] Thirdly, each flow channel requires a limiting mechanism, namely a rotary cylinder and a limiting plate, and the limiting structure is complex.

[0008] Fourthly, when a single flow channel is limited, when the cylinder controls the limiting plate to rotate 90 degrees, the trajectory of the rotation of the limiting plate is along the gap between the sample bottle and the flow channel; when the sample bottle itself is slightly deformed and the bottle placement position is close to the inner wall of the flow channel, there is a probability that the rotation of the limiting plate will be blocked, affecting the development of automated operations.

[0009] Fifthly, since the positions of the sample bottles sent out by each flow channel are different, a sample bottle handling mechanism is also required to push the sample bottles to the next unified work station. The sample bottle handling mechanism drives a push plate through a cylinder, and the push plate pushes the sample bottle. When the cylinder speed is too fast or the sample bottle is deformed and the force is uneven, the sample bottle will tip over during the movement, affecting the development of automated operations.

[0010] Sixthly, in order to adapt to sample bottles of different sizes, the device is provided with a total of 4 flow channels, 4 bottle placement openings, 3 for small bottles and 1 for large bottles. This structure is relatively restricted (the large and small bottles must be placed corresponding to the flow channels and cannot be disordered), resulting in a reduction in work efficiency. Summary of the Invention

[0011] The technical problem to be solved by the present invention is: aiming at the problems existing in the prior art, to provide a rotary drum bottle aligning machine for material sampling, preparation and analysis, which has a simple and compact structure, high automation degree, is easy to manufacture and maintain, has high running stability, and can improve work efficiency.

[0012] To solve the above technical problems, the present invention adopts the following technical solutions:

[0013] A rotary drum bottle aligning machine for material sampling, preparation and analysis includes a frame. A rotary drive mechanism, a rotary drum mechanism and a bottom mechanism are provided on the frame. The rotary drive mechanism drives the rotary drum mechanism to perform a rotary motion on the bottom mechanism. The rotary drum mechanism includes a plurality of vertically arranged rotary drums. Each rotary drum can vertically stack a plurality of sample bottles into the drum in sequence through the top opening. An unloading bottle opening for the sample bottles to pass through is opened on the bottom mechanism. A bottle blocking groove is horizontally opened on the side wall of each rotary drum. A horizontally arranged limiting plate assembly is also fixed on the frame. When the rotary drive mechanism drives the rotary drum to be unloaded and stops at the unloading bottle opening, the limiting plate assembly just snaps into the bottle blocking groove of the rotary drum to be unloaded, so as to limit the sample bottles above the limiting plate assembly and prevent them from falling downward.

[0014] As a further improvement of the present invention, the bottom mechanism includes a bottom plate and a door opening and closing assembly. The bottom plate is arranged below the rotary drum mechanism to enable the rotary drum mechanism to rotate on the top surface of the bottom plate. The unloading bottle opening is opened on the bottom plate. The door opening and closing assembly is arranged below the bottom plate to seal or open the unloading bottle opening.

[0015] As a further improvement of the present invention, the door opening assembly includes a door opening cylinder and a door panel. The door opening cylinder drives the door panel to move below the bottom plate for sealing or opening the unloading bottle mouth with the door panel.

[0016] As a further improvement of the present invention, the rotating cylinder mechanism includes a rotating shaft, an upper connecting plate and a lower connecting plate which are arranged parallel up and down. A plurality of the rotating cylinders are sequentially wound and fixed on the circumferential surfaces of the upper connecting plate and the lower connecting plate to form a cylindrical rotating cylinder mechanism. The rotating shaft vertically penetrates through the upper connecting plate and the lower connecting plate, and both the upper and lower ends of the rotating shaft are rotatably fixed on the machine frame through a bearing seat. The rotation driving mechanism drives the rotating shaft to rotate to drive all the rotating cylinders to rotate simultaneously.

[0017] As a further improvement of the present invention, two or more horizontal bottle blocking grooves which are arranged parallel up and down are transversely formed on the side wall of each rotating cylinder according to the height of different sample bottles. The limiting plate assembly is detachably installed on the machine frame to adjust the installation position according to different sample bottles loaded in the rotating cylinder and be clamped into the bottle blocking grooves at different heights.

[0018] As a further improvement of the present invention, the machine frame includes a top plate, two vertically arranged side rods and a base plate. The upper and lower ends of the two side rods are respectively connected to the top plate and the base plate. The limiting plate assembly includes a horizontally arranged limiting plate and mounting plates fixed at both ends of the limiting plate. The two mounting plates are respectively installed on the two side rods.

[0019] As a further improvement of the present invention, the rotation driving mechanism includes a stepping motor and a coupling. The stepping motor is fixed on the top of the machine frame, and the driving shaft is connected to the top of the rotating shaft through the coupling.

[0020] As a further improvement of the present invention, a concave portion is provided on the bottle body of each sample bottle. When the limiting plate assembly is clamped into the bottle blocking groove, it is just clamped into the concave portion for limiting the sample bottle.

[0021] As a further improvement of the present invention, a limiting slide rail is arranged below the bottom plate near the unloading bottle mouth. The door panel is slidably installed on the limiting slide rail. The driving end of the door opening cylinder is connected to the door panel and used to drive the door panel to slide back and forth to seal or open the unloading bottle mouth.

[0022] Compared with the prior art, the advantages of the present invention are as follows:

[0023] First, the rotary bottle aligning machine for material sampling, preparation and analysis of the present invention completes the bottle aligning of different sample bottles by arranging multiple vertically arranged rotary drums (the number of rotary drums can be flexibly increased or decreased according to needs), and uses its own gravity to complete the preliminary bottle aligning and stacking and the subsequent unified conveying, which is completely different from the existing belt conveying mode, greatly reducing the manufacturing cost and maintenance cost. Moreover, this structure greatly reduces the space occupation and makes the equipment integration degree higher.

[0024] Second, the rotary bottle aligning machine for material sampling, preparation and analysis of the present invention uses its own gravity to complete the preliminary bottle aligning and stacking and the subsequent unified conveying, completely overcoming the problems of slipping or bottle overturning caused by the friction between the sample bottle and the belt in the prior art, greatly improving the working efficiency and operation stability, and being extremely convenient for the development of automated operations.

[0025] Third, the rotary bottle aligning machine for material sampling, preparation and analysis of the present invention, through the rotary design, enables all the rotary drums to pass through the same bottle discharging port, that is, it can be directly docked with the next operation station under the bottle discharging port, without the need to set up a sample bottle handling mechanism after the bottle discharging, greatly reducing the manufacturing cost and maintenance cost, improving the automation and working efficiency, and avoiding many technical problems caused by the pusher plate pushing the sample bottle in the prior art.

[0026] Fourth, the rotary bottle aligning machine for material sampling, preparation and analysis of the present invention has strong adaptability. The sizes of all the rotary drums are the same, and they can be loaded with large bottles or small bottles. The sample bottles in the rotary drums will not fall over, making the bottle loading convenient and fast, and greatly improving the working efficiency.

[0027] Fifth, the rotary bottle aligning machine for material sampling, preparation and analysis of the present invention, by setting the bottle blocking groove and the limit plate assembly, enables only one limit mechanism to correspond to multiple rotary drums, instead of setting a limit mechanism for each flow channel as in the previous technology. The limit structure is simple and easy to manufacture and maintain.

[0028] Sixth, the rotary bottle aligning machine for material sampling, preparation and analysis of the present invention utilizes the rotation action that the rotary drum mechanism itself needs to perform to complete the limiting operation of the limit plate assembly, without setting a limiting power for the limit plate assembly. It is limited when rotated and released from the limit when rotated away. The limit structure and the limit operation are both simple and easy to manufacture and maintain.

[0029] Seventh, the rotary bottle aligning machine for material sampling, preparation and analysis of the present invention, with the cooperation of the limit plate assembly and the design of the upright sample bottle, overcomes the problems of limit obstruction or limit bottle overturning existing in the prior art, greatly improving the working efficiency and stability.

[0038] The following further elaborates on the present invention in detail in conjunction with specific embodiments and the accompanying drawings.

[0039] As Figures 1 to 6 shown, the present invention provides a rotary bottle arranging machine for material sampling, preparation and analysis, including a frame 1. The frame 1 is provided with a plurality of fixed holes and fixing parts for fixedly installing the frame 1 on the working station. The frame 1 is provided with a rotary drive mechanism 2, a rotary drum mechanism 3 and a bottom mechanism 4. The rotary drive mechanism 2 drives the rotary drum mechanism 3 to perform a rotary motion on the bottom mechanism 4. The rotary drum mechanism 3 includes a plurality of vertically arranged rotary drums 31. Each rotary drum 31 can sequentially stack a plurality of sample bottles vertically from the top opening into the drum (as B in the attached drawings is the sample bottle). The bottom mechanism 4 is provided with a bottle unloading opening for the sample bottles to pass through. A bottle blocking groove 311 is horizontally opened on the side wall of each rotary drum 31. A horizontally arranged limit plate assembly 5 is also fixed on the frame 1. When the rotary drive mechanism 2 drives the rotary drum 31 to be unloaded and stops at the bottle unloading opening, the limit plate assembly 5 just snaps into the bottle blocking groove 311 of the rotary drum 31 to be unloaded, so as to limit the sample bottles above the limit plate assembly 5 and prevent them from falling downward.

[0040] During the bottle sorting operation, the upstream manipulator (or other conveying equipment or manual labor) drops the sample bottles into the rotating drum 31 from the top opening of the rotating drum 31. For example, the sample bottles of the same sample variety are all dropped into the same rotating drum 31, and the sample bottles of different samples or the sample bottles of different weight specifications are loaded into different rotating drums 31, so that the classification of different sample bottles is completed, achieving the purpose of bottle sorting.

[0041] During the above loading process, the rotating drum 31 exactly at the bottle unloading port is inserted into the bottle blocking groove 311 by the limit plate assembly 5. Therefore, the first sample bottle placed in this rotating drum 31 can only be placed on the limit plate assembly 5 and then stacked in sequence; while the bottommost sample bottle in each of the other rotating drums 31 can be directly placed on the bottom mechanism 4 and then stacked and stored in sequence. For example, assuming that each rotating drum 31 can hold 10 sample bottles and the bottle blocking groove 311 of the rotating drum 31 is opened between the 1st and the 2nd from the bottom up, then at this time, only 9 sample bottles can be stacked and stored in the rotating drum 31 exactly at the bottle unloading port, while 10 sample bottles can be stacked and stored in each of the other rotating drums 31.

[0042] In order to convey the sample bottles of this rotating drum bottle sorter to the next working station one by one, which is convenient for the next working station to receive and process. The present invention provides a limit plate assembly 5. The limit plate assembly 5 is correspondingly arranged at the bottle unloading port. In this embodiment, the setting height of the limit plate assembly 5 is exactly higher than the top of the bottommost sample bottle in the rotating drum 31, so that the bottommost sample bottle will not be restricted and can fall. Of course, the height of the limit plate assembly 5 can also be set to the height of two sample bottles, so that two sample bottles fall at a time. It is specifically set according to needs. The specific implementation principle is as follows:

[0043] In this embodiment, after all the sample bottles are classified and loaded, they need to be conveyed to the next station. At this time, the rotary drive mechanism 2 drives the rotary drum mechanism 3 to rotate, so that a certain rotary drum 31 to be unloaded stops at the bottle unloading port. When rotating, the limit plate assembly 5 will first snap into the bottle retaining groove 311 of the rotary drum 31 to be unloaded, forming a limit for the penultimate sample bottle. At this time, since it has not rotated completely into place, the sample bottle at the bottom will not fall. When the rotary drum 31 rotates completely and stops at the bottle unloading port, the sample bottle at the bottom of the rotary drum 31 falls downward through the bottle unloading port to the next station, while the sample bottles above the penultimate sample bottle are all limited and cannot fall. After the bottles are unloaded from the rotary drum 31, the rotary drive mechanism 2 then drives the rotary drum mechanism 3 to rotate. At this time, the rotary drum 31 to be unloaded is released from the limit of the limit plate assembly 5, causing the original penultimate sample bottle to fall and become the current bottom sample bottle. During this rotation process, the second rotary drum 31 performs the same rotation and bottle unloading operation as above. And so on. Since the limit plate assembly 5 snaps into the bottle retaining groove 311 of the rotary drum 31, it protrudes and forms a limit for the sample bottles. Regarding the specific limiting method, it can either snap into the concave part on the body of the sample bottle as described below, or directly squeeze into the gap between two sample bottles (as long as the limit plate assembly 5 is made thin and its height position corresponds to the gap between two sample bottles, it will naturally squeeze into the gap between the two sample bottles).

[0044] Through the above special design, the following technical advantages are achieved:

[0045] First, the rotary drum bottle arranging machine for material sampling, preparation and analysis of the present invention uses a plurality of vertically arranged rotary drums 31 to complete the bottle arranging of different sample bottles (the number of rotary drums 31 can be flexibly increased or decreased according to needs), and uses its own gravity to complete the preliminary bottle arranging and stacking and the subsequent unified conveying, which is completely different from the existing belt conveying mode, greatly reducing the manufacturing cost and maintenance cost. Moreover, this structure greatly reduces the space occupation and makes the equipment integration degree higher.

[0046] Second, the rotary drum bottle arranging machine for material sampling, preparation and analysis of the present invention uses its own gravity to complete the preliminary bottle arranging and stacking and the subsequent unified conveying, completely overcoming the problems of slipping or bottle overturning caused by the friction between the sample bottle and the belt in the prior art, greatly improving the work efficiency and operation stability, and being extremely convenient for the development of automated operations.

[0047] Third, the rotary drum bottle arranging machine for material sampling, preparation and analysis of the present invention, through the rotary design, enables all the rotary drums 31 to pass through the same bottle unloading port, that is, it can directly dock with the next operation station below the bottle unloading port, without the need to set up a sample bottle handling mechanism after the bottles are out, greatly reducing the manufacturing cost and maintenance cost, improving the automation and work efficiency, and avoiding many technical problems caused by the pusher pushing the sample bottles in the prior art.

[0048] Fourthly, the rotary bottle arranging machine for material sampling, preparation and analysis of the present invention has strong adaptability. All the rotary cylinders 31 are of the same size and can hold both large bottles and small bottles. The sample bottles in the rotary cylinders 31 will not fall over, making it convenient and fast to load the bottles, and greatly improving the working efficiency.

[0049] Fifthly, for the rotary bottle arranging machine for material sampling, preparation and analysis of the present invention, by providing the bottle blocking groove 311 and the limit plate assembly 5, only one limit mechanism is needed to correspond to multiple rotary cylinders 31, instead of setting a limit mechanism for each flow channel as in the previous technology. The limit structure is simple and easy to manufacture and maintain.

[0050] Sixthly, for the rotary bottle arranging machine for material sampling, preparation and analysis of the present invention, the limit operation of the limit plate assembly 5 is completed by utilizing the rotation movement that the rotary cylinder mechanism 3 itself needs to perform. There is no need to set a limit power for the limit plate assembly 5. When it rotates over, it is limited, and when it rotates away, it is out of limit. Both the limit structure and the limit operation are simple and easy to manufacture and maintain.

[0051] Seventhly, for the rotary bottle arranging machine for material sampling, preparation and analysis of the present invention, the limit plate assembly 5 cooperates with the design of the upright sample bottles, overcoming the problems of limit obstruction or limit bottle overturning existing in the prior art, and greatly improving the working efficiency and stability.

[0052] As Figures 1 to 4 shown, further, in a preferred embodiment, the bottom mechanism 4 includes a bottom plate 41 and a door opening assembly 42. The bottom plate 41 is arranged below the rotary cylinder mechanism 3 so that the rotary cylinder mechanism 3 rotates on the top surface of the bottom plate 41. The unloading bottle opening is arranged on the bottom plate 41. The door opening assembly 42 is arranged below the bottom plate 41 to seal or open the unloading bottle opening. In this embodiment, the bottom plate 41 is a circular plate, which just matches the design of the upper cylindrical rotary cylinder mechanism 3, enabling the bottom plate 41 to support the bottoms of all the rotary cylinders 31 without occupying too much area. The unloading bottle opening can be designed to be exactly the diameter of the rotary cylinder 31 or slightly larger than the diameter of the rotary cylinder 31. In this embodiment, the door opening assembly 42 includes a door opening cylinder 421 and a door plate 422. The door opening cylinder 421 drives the door plate 422 to move below the bottom plate 41 to seal or open the unloading bottle opening with the door plate 422. A limit slide rail is arranged below the bottom plate 41 near the unloading bottle opening. The door plate 422 is slidably installed on the limit slide rail. The driving end of the door opening cylinder 421 is connected to the door plate 422 to drive the door plate 422 to slide back and forth.

[0053] By setting the bottle-opening component 42, when a rotating cylinder 31 finishes unloading bottles and rotates the second rotating cylinder 31 to the bottle-unloading opening, if it is not desired to immediately unload bottles from the second rotating cylinder 31 at this time, the bottle-unloading opening can be sealed by the bottle-opening component 42. The bottle-unloading opening can be opened again when bottle unloading is allowed. Such a setting further meets the requirements of other sample preparation devices. For example, if the downstream docking device needs to suddenly pause bottle unloading, it can be immediately achieved. Further, in a preferred embodiment, the rotating cylinder mechanism 3 includes a rotating shaft 32, an upper connecting plate 33 and a lower connecting plate 34 which are arranged parallel to each other up and down. A plurality of rotating cylinders 31 are sequentially wound and fixed on the circumferential surfaces of the upper connecting plate 33 and the lower connecting plate 34 to form a cylindrical rotating cylinder mechanism 3. The rotating shaft 32 is vertically penetrated through the upper connecting plate 33 and the lower connecting plate 34 (fixedly connected), and both the upper and lower ends of the rotating shaft 32 are rotatably fixed on the frame 1 through a bearing seat 35. The rotation driving mechanism 2 drives the rotating shaft 32 to rotate to drive all the rotating cylinders 31 to rotate simultaneously.

[0054] As Figures 1 to 6 shown, further, in a preferred embodiment, two or more horizontally arranged bottle-blocking grooves 311 which are parallel to each other up and down are transversely formed on the side wall of each rotating cylinder 31 according to different sample bottle heights. The limiting plate assembly 5 is detachably installed on the frame 1 to adjust the installation position according to different sample bottles loaded in the rotating cylinder 31 and to be clamped into the bottle-blocking grooves 311 at different heights. In this embodiment, two bottle-blocking grooves 311 are formed on the side wall of each rotating cylinder 31. The lower bottle-blocking groove 311 is just used to limit the short sample bottles. When all the sample bottles loaded in the rotating cylinder 31 are tall sample bottles, the limiting plate assembly 5 can be disassembled and installed in accordance with the higher bottle-blocking groove 311 for limiting the tall sample bottles. This design makes the rotating cylinder bottle-aligning machine highly adaptable and capable of adapting to sample bottles of various heights.

[0055] As Figures 1 to 4 shown, further, in a preferred embodiment, the frame 1 includes a top plate 11, two vertically arranged side rods 12 and a base plate 13. The upper and lower ends of the two side rods 12 are respectively connected to the top plate 11 and the base plate 13. The limiting plate assembly 5 includes a horizontally arranged limiting plate 51 and mounting plates 52 fixed at both ends of the limiting plate 51. The two mounting plates 52 are respectively installed on the two side rods 12. The top plate 11 is used to install the rotation driving mechanism 2. Both the upper and lower ends of the rotating shaft 32 are rotatably fixed on the top plate 11 and the base plate 13 through a bearing seat 35. The bottom plate 41 is also fixed on the base plate 13. This structure makes the operation highly stable.

[0056] Further, in a preferred embodiment, the rotation driving mechanism 2 includes a stepper motor 21 and a coupling 22. The stepper motor 21 is fixed on the top of the frame 1, and the driving shaft is connected to the top of the rotating shaft 32 through the coupling 22.

[0057] As Figure 5 、Figure 6 As shown, further, in a preferred embodiment, the rotary bottle aligning machine for material sampling and preparation of the present invention is also equipped with a plurality of sample bottles. A concave portion (shown as C in the figure) is provided on the body of each sample bottle. When the limit plate assembly 5 is inserted into the bottle blocking groove 311, it is exactly inserted into the concave portion to limit the sample bottle. This design makes the limit simple, convenient and stable.

[0058] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should be regarded as within the protection scope of the present invention.
