Description

Technical Field

[0001] This invention relates to the field of sample bottle transfer machinery technology, and specifically discloses a fully automatic sample bottle cleaning system. Background Technology

[0002] In the field of coal mining and chemistry, plastic sample bottles are generally used for storing and transporting coal samples. To avoid cross-contamination affecting analytical results and to prevent dirt on the bottle from affecting sensor sensitivity, the sample bottles need to be cleaned and dried so that they can be reused.

[0003] Currently, the industry typically uses manual or semi-automatic equipment to clean coal sample bottles. Manual cleaning involves immersing the sample bottles in water, wiping them with cloths and brushes, and then allowing them to air dry. Semi-automatic equipment still requires manual handling of sample bottle transfer, capping, disposal, placement, and removal; only the cleaning and drying steps are completed by the machine. These methods all require manual intervention, resulting in high labor intensity, poor working conditions, generally poor cleaning results, low efficiency, and low automation, failing to meet the requirements of intelligent development in the coal-fired power industry. Existing sample bottle cleaning equipment mainly suffers from the following drawbacks: 1. Existing sample bottle cleaning equipment is mainly used for cleaning glass sample bottles on packaging lines for pharmaceuticals, beverages, and alcoholic beverages, and is not universally applicable for cleaning plastic sample bottles. 2. Most existing sample bottle cleaning equipment is semi-automatic, requiring manual operation of opening caps, discarding materials, placing bottles, and taking bottles out, which cannot achieve fully unmanned operation.

[0004] 3. For example, CN219805091U discloses a fully automatic bottle washing and drying system, which includes a frame. The frame is equipped with a pneumatic receiving and dispatching module, a sample bottle storage module, a robotic arm module, a cap opening and closing and bottle cap cleaning module, a material pouring and cleaning module, a high-pressure spray washing module, a water washing and drying module, a water circuit control module, and control components. The pneumatic receiving and dispatching module is used to receive and dispatch sample bottles; the sample bottle storage module is used to store sample bottles; the robotic arm module is used to transfer sample bottles; the cap opening and closing and bottle cap cleaning module is used to open, close, and clean the sample bottles; the material pouring and cleaning module is used to pour and clean the sample from the sample bottles; the high-pressure spray washing module is used to perform rough cleaning of the sample bottles; the water washing and drying module is used to perform ultrasonic cleaning, contact brushing, and drying of the sample bottles; the water circuit control module is used to provide clean water and discharge the wastewater after cleaning; and the control components are used to control the operation of each module. Although this technical solution achieves fully automated cleaning and drying of coal sample bottles without human intervention, it uses a single robotic arm module to move the sample bottles between different workstations within the equipment, which cannot achieve continuous cleaning operations in an assembly line manner, resulting in low efficiency.

[0005] Therefore, there is an urgent need for a cleaning system that is versatile in cleaning both glass and plastic sample bottles and can achieve continuous bottle washing in an assembly line. Summary of the Invention

[0017] (III) Beneficial Effects Compared with existing technologies, the fully automated sample bottle cleaning system and its testing method of the present invention have the following advantages: This fully automated sample bottle cleaning system, through the setting of a rotary unit, ensures that its bottle receiving unit, cap opening unit, waste disposal unit, ultrasonic cleaning unit, spray scrubbing unit, drying unit, cap closing unit, and bottle dispensing unit are all symmetrically distributed around the rotary unit as the central axis.

[0023] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] The following is in conjunction with the appendix Figure 1-7 The fully automated sample bottle cleaning system and its testing method of the present invention will be further described.

[0025] Please refer to this carefully. Figure 1-2 This invention discloses a fully automatic sample bottle cleaning system, which includes: a rotary unit 1, a bottle receiving unit 2, a cap opening unit 3, a waste disposal unit 4, an ultrasonic cleaning unit 5, a spray scrubbing unit 6, a drying unit 7, a cap closing unit, and a bottle dispensing unit. The bottle receiving unit 2, cap opening unit 3, waste disposal unit 4, ultrasonic cleaning unit 5, spray scrubbing unit 6, drying unit 7, cap closing unit, and bottle dispensing unit are arranged in a circular pattern, and are symmetrically distributed with the rotary unit 1 as the axis. After the sample bottle enters the fully automatic sample bottle cleaning system, it passes through the bottle receiving unit 2 in sequence, then through the cap opening unit 3, waste disposal unit 4, ultrasonic cleaning unit 5, spray scrubbing unit 6, drying unit 7, and cap closing unit.

[0026] In this embodiment, the fully automatic sample bottle cleaning system, through the setting of the rotary unit 1, ensures that the bottle receiving unit 2, cap opening unit 3, waste disposal unit 4, ultrasonic cleaning unit 5, spray brushing unit 6, drying unit 7, cap closing unit, and bottle dispensing unit are all symmetrically distributed around the rotary unit 1 as the axis. This allows the sample bottles to automatically flow between the various working units within the cleaning system after entering the cleaning system through the rotary unit 1 located at the center. As a result, the fully automatic sample bottle cleaning system can automatically complete the entire process of bottle receiving, cap opening, waste disposal, ultrasonic rough cleaning, spray brushing, drying, cap closing, and bottle dispensing without human intervention, achieving a high degree of automation.

[0027] Furthermore, in a preferred embodiment, when the system starts working, the bottle receiving unit 2 first receives the No. 1 sample bottle to be cleaned. After receiving the No. 1 sample bottle, the #1 clamping mechanism of the rotary unit 1 at the bottle receiving station clamps the No. 1 sample bottle and rotates it clockwise by 45°, transferring the No. 1 sample bottle to the cap opening station. At the cap opening station, the cap opening unit 3 opens the cap of the No. 1 sample bottle; at this time, the bottle receiving unit 22 can receive the No. 2 sample bottle transferred by the pneumatic conveying system. After the cap opening of the No. 1 sample bottle is completed, the rotary unit 1 continues to rotate clockwise by 45°, and the #1 clamping mechanism transfers the No. 1 sample bottle to the waste disposal station. At this time, the #2 clamping mechanism transfers the No. 2 sample bottle to the cap opening station; while the waste disposal unit 4, the cap opening unit 3, and the bottle receiving unit 2 simultaneously perform waste disposal, cap opening, and bottle receiving operations on the No. 1, No. 2, and No. 3 sample bottles, respectively. Subsequently, the rotary unit 1 repeats the action of rotating 45° clockwise. The #1 clamping mechanism sequentially transfers sample bottle No. 1 to the ultrasonic cleaning station, spray washing station, drying station, capping station, and air conveying station, completing the entire bottle washing process of sample bottle No. 1 receiving → capping → discarding → ultrasonic cleaning → spray washing → drying → capping → bottle dispensing. At the same time, multiple clamping mechanisms clamp multiple sample bottles and sequentially transfer them to other stations, with each station performing the work on different sample bottles simultaneously at a certain time. After sample bottle No. 1 is dispensed, the #1 clamping mechanism rotates back to the receiving station and clamps sample bottle No. 9 to begin the next round of transfer work. Thus, the 8 clamping mechanisms of the rotary unit 11, in coordination with 8 functional modules, work in a cycle, ensuring that the functional modules of each station are working at the same time, forming a streamlined sample bottle cleaning process.

[0028] In summary, this fully automated sample bottle cleaning system, through the clamping mechanism in rotary unit 1, provides multiple clamping mechanisms for each working unit, thereby enabling the transfer of sample bottles between various workstations. The number of clamping mechanisms corresponds one-to-one with the number of functional modules, further ensuring that sample bottles are present at each workstation for processing at the same time. This prevents the overall system efficiency from being affected by the operating efficiency of rotary unit 1, thus improving the cleaning efficiency of the sample bottles. Furthermore, the unidirectional circulation of sample bottles in rotary unit 1 creates a streamlined cleaning process between the bottle receiving → capping → discarding → ultrasonic cleaning → spray washing → drying → capping → bottle dispensing workstations, further facilitating automated cleaning during use and increasing the overall automation level of the cleaning system. Furthermore, the bottle receiving unit 2, cap opening unit 3, waste disposal unit 4, ultrasonic cleaning unit 5, spray brushing unit 6, drying unit 7, cap closing unit, and bottle dispensing unit are arranged in a circular arrangement around the rotating unit 1. This circular arrangement makes the structure of the fully automatic sample bottle cleaning system more compact, further saving equipment space and facilitating installation, disassembly, and maintenance during use.

[0029] like Figure 3As shown, the rotary unit 1 includes a base 11, a drive mechanism, a rotary disk 13, and a clamping mechanism. The rotary disk 13 is rotatably mounted on the base 11. The drive mechanism is fixedly mounted on the base 11 and connected to the rotary disk 13 to drive the rotary disk 13 to rotate. Multiple clamping mechanisms are evenly spaced along the circumferential direction of the outer periphery of the rotary disk 13 to clamp and flip the sample bottles. The drive mechanism is preferably a servo geared motor 12.

[0030] Its clamping mechanism includes a mounting base, a tilting cylinder 42114, a pneumatic finger 15, and grippers 16. The mounting base is fixedly connected to the rotary table 13. The pneumatic finger 15 is rotatably mounted on the side wall of the mounting base. The tilting cylinder 42114 is fixedly mounted on the mounting base and connected to the pneumatic finger 15 to drive the tilting of the pneumatic finger 15. The grippers 16 are respectively mounted on the two fingers of the pneumatic finger 15 so that the pneumatic finger 15 drives the opening and closing of the pair of grippers 16.

[0031] In this embodiment, the fully automatic cleaning system achieves continuous, assembly-line transfer of sample bottles between various functional modules through the rotary unit 1. Its base 11 is located at the central axis of the fully automatic sample bottle cleaning system, and a servo reduction motor 12 is fixedly mounted on the base 11, driving the rotary table 13 to rotate clockwise. A tilting cylinder 42114, pneumatic fingers 15, and grippers 16 form a sample bottle tilting and clamping mechanism. When the pneumatic fingers 15 close, they drive the grippers 16 to clamp the sample bottle; when the pneumatic fingers 15 open, they drive the grippers 16 to release the sample bottle. The tilting cylinder 42114 drives the pneumatic fingers 15 to rotate 180°, thereby causing the sample bottle held by the clamping mechanism to rotate 180°, changing the bottle opening from facing upwards to facing downwards. Multiple sets of the above-mentioned sample bottle tilting and clamping mechanisms are evenly spaced and correspond to the spacing of each working unit, fixed at the circumference of the rotary table 13, rotating clockwise with the rotary table 13, thus achieving fully automatic cleaning and transfer of sample bottles.

[0032] See Figure 4 The waste unit 4 includes a waste vibration device 42 and a waste collection trough 41. The waste vibration device 42 contacts the gripper 16 to drive the sample bottle on the gripper 16 to vibrate. The waste collection trough 41 is located below the waste vibration device 42 to collect impurities that fall off the sample bottle during vibration. The waste vibration device 42 includes a frame, a cylinder 421, a connecting plate 422, a pneumatic vibrator 423, a connecting rod 424, a spring 425, and a vibrating plate 426. The cylinder 421 is fixedly mounted on the frame. The output end of the cylinder 421 is provided with the connecting plate 422. One end of the connecting rod 424 is fixedly mounted on the vibrating plate 426, and the other end of the connecting rod 424 is detachably connected to the connecting plate 422. The pneumatic vibrator 423 is mounted on the connecting plate 422, and the output end of the pneumatic vibrator 423 is connected to the vibrating plate 426 to drive the vibrating plate 426 to vibrate. The connecting rod 424 is fitted with a spring 425.

[0033] In this embodiment, the waste collection trough 41 is responsible for collecting the waste from the sample bottles. When the clamping mechanism clamps the sample bottle with the cap open and transfers it to the waste collection unit 4, the tilting cylinder 42114 drives the sample bottle to tilt 180° to pour out the waste, which is then poured into the waste collection trough 41. If the coal sample in the sample bottle is high-viscosity wet coal with a high moisture content, and it sticks to the inner wall of the sample bottle and cannot be poured out smoothly, the waste vibration device 42 vibrates the sample bottle to break up the wet coal arching, allowing the wet and sticky coal to be poured out smoothly. The waste material vibration device 42 includes a cylinder 421, a connecting plate 422, a pneumatic vibrator 423, a connecting rod 424, a spring 425, and a vibrating plate 426. The cylinder 421 is fixedly mounted on the frame. When the rotary unit 1 is activated, the cylinder 421 drives the waste material vibration device 42 to retract, avoiding interference. When the sample bottle is being discarded, the cylinder 421 drives the waste material vibration device 42 to extend, the vibrating plate 426 is pressed against the outer wall of the sample bottle, the pneumatic vibrator 423 is activated, and the vibration is transmitted to the sample bottle through the vibrating plate 426 to help the wet coal fall off. One end of the connecting rod 424 is fixed to the vibrating plate 426, and the other end is movably mounted on the connecting plate 422. By combining with the spring 425, the vibration transmitted to the connecting plate 422 is reduced, preventing damage to the piston rod of the cylinder 421 due to strong vibration.

[0034] like Figure 5 As shown, the ultrasonic cleaning unit 5 includes an ultrasonic tank 51, an ultrasonic source 52, a cleaning lifting cylinder 53, and a bottle support plate 54; the central axis of the bottle support plate 54 can coincide with the central axis of the gripper 16; the cleaning lifting cylinder 53 is provided on the inner side wall of the ultrasonic tank 51; the bottle support plate 54 is provided on the slider of the cleaning lifting cylinder 53; and the ultrasonic source is provided at the bottom of the ultrasonic tank 51.

[0035] In this embodiment, the ultrasonic tank 51 is filled with cleaning water, an ultrasonic source 52 is installed at the bottom of the tank, and a cleaning lifting cylinder 53 is installed on the side wall of the tank. A bottle support plate 54 is mounted on the slider of the cleaning lifting cylinder 53 and can move up and down. When the robotic arm, having finished handling the discarded sample bottle, transfers it to the ultrasonic cleaning station, the robotic arm gripper 16 releases, allowing the sample bottle to fall onto the bottle support plate 54. The cleaning lifting cylinder 53 drives the bottle support plate 54 to lower the sample bottle into the ultrasonic cleaning tank. The ultrasonic source 52 then operates, vibrating and dispersing the dirt adhering to the inside and outside of the sample bottle. After cleaning, the cleaning lifting cylinder 53 drives the bottle support plate 54 to rise and leave the ultrasonic cleaning tank. The robotic arm gripper 16 then clamps the cleaned sample bottle and transfers it to the next station.

[0036] See Figure 6The spray scrubbing unit 6 includes a scrubbing tank 61, a scrubbing lifting cylinder 62, a scrubbing connecting seat 63, and a scrubbing mechanism. The central axis of the scrubbing connecting seat 63 can coincide with the central axis of the gripper 16. The scrubbing connecting seat 63 is set on the slider of the scrubbing lifting cylinder 62. The scrubbing lifting cylinder 62 is set on the inner side wall of the scrubbing tank 61. The scrubbing mechanism is set on the scrubbing connecting seat 63 to scrub the side wall of the sample bottle. The washing mechanism includes a washing drive motor 64, a rotary joint 65, a rotating shaft, an inner wall spray pipe 66, an outer wall spray pipe 67, an inner wall brush 68, and an outer wall brush 69. The washing drive motor 64 is located at the bottom of the washing connecting seat 63. The rotating shaft is rotatably located at the bottom of the washing connecting seat 63 and coincides with the central axis of the washing connecting seat 63. The rotating shaft passes through the washing connecting seat 63 and is connected to the output end of the washing drive motor 64. The inner wall spray pipe 66 and the inner wall brush 68 are provided on the rotating shaft to clean the inner wall of the sample bottle. The washing mechanism also includes a washing bracket fixedly connected to the rotating shaft. The outer wall brush 69 and the outer wall spray pipe 67 are provided on the washing bracket. The outer wall brush 69, the outer wall spray pipe 67, and the inner wall brush 68 are of the same height and are distributed around the inner wall spray pipe 66 and the inner wall brush 68.

[0037] In this embodiment, the scrubbing tank 61 is used to collect wastewater after rinsing sample bottles. Notches are provided at the upper ends of both sides to facilitate the entry and exit of sample bottles by a robotic arm. A scrubbing lifting cylinder 62 is installed on the side wall of the tank, and a connecting seat is mounted on the slider of the scrubbing lifting cylinder 62, allowing it to move up and down. A scrubbing drive motor 64 is installed at the lower end of the connecting seat, and an inner wall spray pipe 66 is installed at the upper end. The scrubbing drive motor 64 can drive the inner wall spray pipe 66 to rotate along its central axis. A rotary joint 65 is also installed between the scrubbing drive motor 64 and the inner wall spray pipe 66, allowing water to be injected into the inner wall spray pipe 66 from the outside while it rotates. The outer wall spray pipe 67 is connected to the inner wall spray pipe 66, allowing water in the inner wall spray pipe 66 to flow to the outer wall spray pipe 67. Both pipes have several small holes on their walls, through which water is sprayed out at a certain pressure to rinse the inner and outer walls of the sample bottle. When the inner wall spray pipe 66 rotates, it can drive the outer wall spray pipe 67 to rotate as well. The inner wall brush 68 is installed at the upper end of the inner wall spray pipe 66, and can perform contact brushing on the inner wall of the sample bottle when the inner wall spray pipe 66 rotates. The outer wall brush 69 is installed at the upper end of the outer wall spray pipe 67, with the bristles facing the inner wall spray pipe 66, and can perform contact brushing on the outer wall of the sample bottle when the outer wall spray pipe 67 rotates around the inner wall spray pipe 66. The working principle of the spray brushing unit 6 is as follows: When the robotic arm clamps the sample bottle that has undergone ultrasonic cleaning and transfers it to the spray brushing station, the bottle opening is facing downwards. The brushing lifting cylinder 62 drives the connecting seat to rise, causing the inner wall brush 68 to extend into the sample bottle, while the outer wall brush 69 is in close contact with the outer wall of the sample bottle. At this time, the brushing drive motor 64 starts, driving the inner wall brush 68 and the outer wall brush 69 to brush the inner and outer sides of the sample bottle. Simultaneously, water is injected into the inner wall spray pipe 66 through the rotary joint 65. The cleaning water sprays and rinses the inner and outer sides of the sample bottle through the small holes on the inner wall spray pipe 66 and the outer wall spray pipe 67. After cleaning is completed, the water injection stops, the brushing drive motor 64 stops starting, and the brushing lifting cylinder 62 drives the inner wall brush 68 to descend and leave the sample bottle. At this time, the sample bottle is transferred to the next station.

[0038] like Figure 7As shown, the drying unit 7 includes a drying tank 71, a drying lifting cylinder 72, a drying connecting seat 73, and a drying mechanism; the drying lifting cylinder 72 is fixedly installed on the inner side wall of the drying tank 71, the drying connecting seat 73 is installed on the slider of the drying lifting cylinder 72, and the drying connecting seat 73 is provided with a drying mechanism to dry the sample bottle. The drying mechanism includes a drying drive motor 74, a rotary joint 7565, an inner wall air duct 76, and an outer wall air duct 77. The drying drive motor 74 is fixedly installed at the bottom of the drying connecting seat 73. The inner wall air duct 76 is installed above the drying connecting seat 73 and passes through the drying connecting seat 73 to connect with the drying drive motor 74 through the rotary joint 7565. The outer wall air duct 77 is fixedly installed on the inner wall air duct 76 and is connected to the inner wall air duct 76. Both the outer wall air duct 77 and the inner wall air duct 76 have multiple ventilation holes to blow the sample bottles.

[0039] In this embodiment, when the clamping mechanism transfers the sample bottle, after spraying and brushing, to the drying unit 7, the bottle opening faces downwards. The drying lifting cylinder 72 drives the connecting seat to rise, causing the inner wall air duct 76 to extend into the sample bottle, and the air outlet of the outer wall air duct 77 to align with the outer wall of the sample bottle. At this time, air is introduced into the inner wall air duct 76 through the rotary joint 7565. The drying air passes through the small holes on the inner wall air duct 76 and the outer wall air duct 77 to dry both the inside and outside of the sample bottle. Simultaneously, the drive motor starts, causing the inner wall air duct 76 and the outer wall air duct 77 to rotate around the sample bottle, achieving 360° coverage and drying of the inside and outside of the sample bottle. After drying is completed, the air intake stops, the drying drive motor 74 stops starting, and the drying lifting cylinder 72 drives the inner wall air duct 76 to descend and leave the sample bottle. At this time, the sample bottle can be transferred to the next station by the robotic arm.

[0040] Furthermore, in a preferred embodiment, the working units in the fully automatic sample bottle washing system can be added or reduced according to actual usage needs, and the clamping mechanism in the rotating unit 1 can be set according to the number of working units.
