Description

Technical Field

[0001] The invention relates to the technical field of bottled water production, and in particular to a positioning cleaning device and a positioning cleaning method for a water outlet valve of a drinking water barrel. Background Art

[0002] At present, most of the domestic pure water processing companies have adopted a highly automated assembly line to produce bottled water. Due to the high cost of manufacturing barrels, companies usually recycle and reuse the barrels. Before the recycled barrels are filled with pure water again, the surface area, interior and water outlet valve of the drinking water barrel need to be cleaned and disinfected.

[0003] Since the water outlet valve of the drinking bucket is in a closed state under normal circumstances, it is necessary to press the valve opening handle of the water outlet valve to open the water outlet valve when taking water, and the water in the drinking bucket will flow out of the water outlet valve; therefore, when cleaning the water outlet valve of the drinking bucket, it is also necessary to clean the inside and outside of the water outlet valve, which puts forward new requirements for the cleaning of the water outlet valve of the drinking bucket. In the related technology, the water outlet valve of the drinking bucket is usually aligned with the nozzle of the spraying mechanism, and then the spraying mechanism is turned on to rinse the outside of the water outlet valve. However, in actual operation, the positioning between the water outlet valve of the drinking bucket and the nozzle of the spraying mechanism is prone to deviation, which makes it impossible for the nozzle to accurately rinse the water outlet valve, and this cleaning method cannot clean the inside of the water outlet valve, which results in inadequate cleaning of the water outlet valve, affecting the reuse of the drinking bucket.

[0004] Therefore, in order to solve the above-mentioned technical problems, it is extremely urgent to develop a positioning cleaning device and a positioning cleaning method for a water outlet valve of a drinking bucket. Summary of the invention

The mounting plate is located above the conveying mechanism. The clamping assembly is rotatably connected to a side of the mounting plate close to the conveying mechanism. The lifting drive drives the clamping assembly to move closer to or away from the conveying mechanism.

[0012] In this implementation, the conveying mechanism conveys the drinking water barrel with the water outlet valve to be cleaned to a preset position, the clamping mechanism clamps the drinking water barrel and rotates, and when the sensing mechanism senses the position of the water outlet valve, the clamping mechanism is controlled to stop rotating so that the drinking water barrel water outlet valve is aligned with the valve opening mechanism, and then the drinking water barrel water outlet valve is aligned with the spraying mechanism.

[0013] In some implementations, the spraying mechanism includes a flushing nozzle and a flushing pipe, wherein the flushing pipe is respectively connected to the flushing nozzle and an external medium source, and the opening of the flushing nozzle is arranged upward.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of them.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment 1: Please refer to the attached Figure 1 ~Attached Figure 3 The positioning and cleaning device of the water outlet valve of the drinking water bucket of the present invention comprises a conveying mechanism 1, a water outlet valve positioning mechanism 2, a valve opening mechanism 3 and a spray cleaning mechanism 4.

[0026] Please combine Figure 1 and Figure 2 , Figure 1 The structure relationship among the conveying mechanism 1, the water outlet valve positioning mechanism 2, the valve opening mechanism 3 and the spraying mechanism 4 in the embodiment of the present invention is shown. Figure 2 The structural relationship between the first positioning component 22 and the valve opening plate 31 in the embodiment of the present invention is illustrated. Specifically, the conveying mechanism 1 is used to convey the drinking water bucket whose water outlet valve is to be cleaned; the water outlet valve positioning mechanism 2 includes a positioning drive component 21 and a first positioning component 22 and a second positioning component 23 arranged on both sides of the conveying mechanism 1; the valve opening mechanism 3 is connected to the first positioning component 22, and the valve opening mechanism 3 includes a valve opening plate 31 connected to the first positioning component 22 and extending toward the conveying mechanism 1; the spraying mechanism 4 is arranged on the side of the conveying mechanism 1 and below the valve opening mechanism 3. Among them, when the positioning drive component 21 drives the first positioning component 22 and the second positioning component 23 to approach the conveying mechanism 1 and clamp the drinking water bucket, the valve opening plate 31 is driven to abut against the valve opening handle of the water outlet valve of the drinking water bucket.

[0027] In this embodiment, the drinking water bucket with the water outlet valve to be cleaned is transported by the conveying mechanism 1. When the drinking water bucket reaches the preset position, the conveying mechanism 1 stops conveying, and the positioning drive component 21 drives the first positioning component 22 and the second positioning component 23 to approach the conveying mechanism 1 and clamp the drinking water bucket, so that the drinking water bucket water outlet valve and the nozzle of the spraying mechanism 4 are pre-positioned. After the pre-positioning is completed, the first positioning component 22 releases the state of clamping the drinking water bucket, and the spraying mechanism 4 starts to clean the outside of the drinking water bucket water outlet valve; when the external cleaning is completed, the positioning drive component 21 drives the first positioning component 22 to approach the conveying mechanism 1 and clamp the drinking water bucket again. The valve opening plate 31 of the valve opening mechanism 3 is connected to a side of the first positioning component 22 close to the conveying mechanism 1. When the first positioning component 22 approaches and clamps the drinking water bucket under the drive of the positioning drive component 21, the valve opening plate 31 will be driven to abut against the valve opening handle of the water outlet valve of the drinking water bucket, so that the water outlet valve of the drinking water bucket is in an open state, so that the spraying mechanism 4 located below the valve opening mechanism 3, that is, below the water outlet valve of the drinking water bucket, can clean the inside of the water outlet valve of the drinking water bucket. In this way, the spraying mechanism 4 can effectively clean both the outside and the inside of the water outlet valve of the drinking water bucket, thereby avoiding the problem of inadequate cleaning of the water outlet valve of the drinking water bucket, which affects the reuse of the drinking water bucket.

[0028] It should be noted that when cleaning the outside of the water outlet valve of the drinking water bucket, the positioning drive component 21 respectively drives the first positioning component 22 and the second positioning component 23 to approach the conveying mechanism 1 and clamp the drinking water bucket. The first positioning component 22 synchronously calibrates the position of the water outlet valve of the drinking water bucket during the process of clamping the drinking water bucket, so that the water outlet valve of the drinking water bucket and the spraying mechanism 4 are accurately aligned, thereby ensuring the reliability of the spraying mechanism 4 in cleaning the water outlet valve of the drinking water bucket.

[0029] The above-mentioned positioning and cleaning device for the water outlet valve of the drinking water bucket ensures that the water outlet valve of the drinking water bucket and the spraying mechanism 4 are accurately aligned because the first positioning component 22 synchronously calibrates the position of the water outlet valve of the drinking water bucket when it approaches the conveying mechanism 1 and clamps the drinking water bucket; and because the valve opening plate 31 of the valve opening mechanism 3 is connected to the side of the first positioning component 22 close to the conveying mechanism 1, when the first positioning component 22 approaches the conveying mechanism 1 and clamps the drinking water bucket, it will drive the valve opening plate 31 to abut against the valve opening handle of the water outlet valve of the drinking water bucket, so that the water outlet valve of the drinking water bucket is in an open state, which is convenient for the spraying mechanism 4 to clean the inside of the water outlet valve of the drinking water bucket; in this way, not only the problem of easy deviation in positioning between the water outlet valve of the drinking water bucket and the nozzle of the spraying mechanism 4 is solved, but also the problem of inadequate cleaning of the water outlet valve of the drinking water bucket is solved.

[0030] In some preferred embodiments, the valve opening plate 31 includes a connecting portion 311 and an abutting portion 312, wherein the connecting portion 311 is closely connected to the side of the first positioning assembly 22 away from the conveying mechanism 1, and the abutting portion 312 is connected to the connecting portion 311 and extends toward the conveying mechanism 1. When the positioning drive mechanism drives the first positioning assembly 22 to approach or move away from the conveying mechanism 1, the connecting portion 311 is synchronously driven to move, and then the abutting portion 312 is driven to switch to abut against the valve opening handle of the water outlet valve of the drinking water bucket or release the state of abutting against the valve opening handle, which further facilitates the spray cleaning mechanism 4 to clean the inside or outside of the water outlet valve of the drinking water bucket, thereby ensuring the reliability of the overall structure.

[0031] In some preferred embodiments, the first positioning assembly 22 includes a first positioning plate 221, and a positioning groove 222 for limiting the movement of the drinking water bucket is provided on one side of the first positioning plate 221 close to the conveying mechanism 1. When the positioning drive assembly 21 drives the first positioning plate 221 close to the conveying mechanism 1 and clamps the drinking water bucket, the outer peripheral wall of the drinking water bucket fits into the positioning groove 222 to limit the position of the drinking water bucket, so that the drinking water bucket and the spraying mechanism 4 are aligned with each other.

[0032] In some more preferred embodiments, see Figure 3 , Figure 3 The structural relationship between the first positioning plate 221, the valve opening mechanism 3 and the calibration mechanism in the embodiment of the present invention is illustrated. Specifically, the first positioning assembly 22 also includes a calibration structure 223 disposed between the first positioning plate 221 and the valve opening mechanism 3, and the calibration structure 223 is used to calibrate the position of the water outlet valve of the drinking water bucket; the calibration structure 223 includes a calibration plate 2231 disposed between the first positioning plate 221 and the valve opening mechanism 3, and the calibration plate 2231 is provided with a calibration groove 2232 for clamping the water outlet valve of the drinking water bucket, and the calibration groove 2232 is located in the middle of the positioning groove 222. When the first positioning plate 221 clamps the drinking water bucket, the calibration structure 223 calibrates the position of the water outlet valve of the drinking water bucket. Specifically, the positioning groove 222 is clamped to the outer peripheral wall of the drinking water bucket, and the calibration groove 2232 on the calibration plate 2231 is clamped to the water outlet valve of the drinking water bucket, so that the water outlet valve of the drinking water bucket and the spray washing mechanism 4 can be accurately aligned. The calibration groove 2232 is located in the middle of the positioning groove 222, which is beneficial for the calibration groove 2232 to fit the outer wall of the drinking water barrel when the water outlet valve of the drinking water barrel is clamped, thereby improving the compactness of the overall structure.

[0033] Embodiment 2: The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the positioning and cleaning device of the water outlet valve of the drinking water bucket of the present invention. Figure 4 ~Attached Figure 5 .

[0034] Among them, see Figure 4 , Figure 4The schematic diagram shows the structural relationship between the clamping mechanism 5 and the sensing mechanism 6 in the embodiment of the present invention. Specifically, the clamping mechanism 5 and the sensing mechanism 6 are included. The clamping mechanism 5 is located above the conveying mechanism 1 and is used to clamp the drinking water bucket and rotate. The sensing mechanism 6 is located above the valve opening mechanism 3 and is used to sense the position of the water outlet valve of the drinking water bucket. The clamping mechanism 5 includes a mounting plate 51, a clamping assembly 52 and a lifting drive 53. The mounting plate 51 is located above the conveying mechanism 1. The clamping assembly 52 is rotatably connected to a side of the mounting plate 51 close to the conveying mechanism 1. The lifting drive 53 drives the clamping assembly 52 to move closer to or away from the conveying mechanism 1.

[0035] In this embodiment, the conveying mechanism 1 conveys the drinking water bucket with the water outlet valve to be cleaned to a preset position, the clamping mechanism 5 clamps the drinking water bucket and rotates, and when the sensing mechanism 6 senses the position of the water outlet valve, the clamping mechanism 5 is controlled to stop rotating so that the drinking water bucket water outlet valve is aligned with the valve opening mechanism 3, and then the drinking water bucket water outlet valve is aligned with the spray cleaning mechanism 4. Specifically, the lifting drive 53 drives the clamping assembly 52 to approach the conveying mechanism 1, and after the clamping assembly 52 clamps the drinking water bucket, the lifting drive 53 drives the clamping assembly 52 away from the conveying mechanism 1, and the clamping assembly 52 rotates to drive the drinking water bucket to rotate, thereby avoiding the friction between the drinking water bucket and the conveying mechanism 1 when rotating, thereby causing the problem of wear.

[0036] It should be noted that when the sensing mechanism 6 senses the position of the water outlet valve of the drinking water bucket, even if there is a small deviation between the position of the water outlet valve and the spray washing mechanism 4 when the clamping assembly 52 stops rotating, when the first positioning plate 221 clamps the drinking water bucket, the drinking water outlet valve can be brought into the calibration groove 2232 of the calibration plate 2231 by the calibration structure 223, so as to achieve accurate positioning between the drinking water outlet valve and the spray washing mechanism 4. Moreover, the clamping assembly 52 clamps the drinking water bucket during the process of cleaning the drinking water outlet valve, plays a role in fixing the drinking water bucket, and avoids the problem of displacement of the drinking water bucket when the water pressure is too high, which leads to positioning failure.

[0037] In some preferred embodiments, please continue to refer to Figure 4 , Figure 4 The specific structure of the spray mechanism 4 in the embodiment of the present invention is also illustrated. Specifically, the spray mechanism 4 includes a flushing nozzle 41 and a flushing pipe 42. The flushing pipe 42 is connected to the flushing nozzle 41 and an external medium source respectively. The opening of the flushing nozzle 41 is set upward. When the spray mechanism 4 performs cleaning work, the opening of the flushing nozzle 41 is aligned with the water outlet valve of the drinking water bucket, so that the flushing nozzle 41 cleans the water outlet valve of the drinking water bucket in a straight line, thereby improving the cleaning effect. It can be understood that the external medium source can be clean water or other liquids or gases used for cleaning and disinfection.

[0038] In some more preferred embodiments, see Figure 5 , Figure 5The diagram shows the structural relationship between the barrel blocking mechanism 7 and the conveying mechanism 1 in the embodiment of the present invention. Specifically, the positioning and cleaning device for the water outlet valve of the drinking water bucket further includes a barrel blocking mechanism 7 arranged on the side of the conveying mechanism 1, and the barrel blocking mechanism 7 includes a barrel blocking block 71 and a barrel blocking driving member 72, and the barrel blocking driving member 72 drives the barrel blocking block 71 to approach or move away from the conveying mechanism 1. The conveying mechanism 1 is arranged in linkage with the barrel blocking mechanism 7, and the conveying mechanism 1 conveys the drinking water buckets whose water outlet valves are to be cleaned. When the external sensor senses that the number of drinking water buckets on the conveying mechanism 1 has reached a preset number, the barrel blocking driving member 72 drives the barrel blocking block 71 to approach the conveying mechanism 1 to stop the drinking water buckets, and at the same time the conveying mechanism 1 stops conveying, and the barrel blocking driving member 72 drives the barrel blocking block 71 away from the conveying mechanism 1 again to ensure the reliability of the overall structure.

[0039] Embodiment 3: Figure 6 FIG. 1 is a flow chart showing an embodiment of a method for positioning and cleaning a water outlet valve of a drinking water bucket according to the present invention. Figure 6 As shown, based on the positioning and cleaning device of the water outlet valve of the drinking water bucket, the method comprises the following steps: S110, clamping the drinking water bucket by the clamping mechanism and rotating it.

[0040] Among them, the clamping assembly of the clamping mechanism clamps the drinking water bucket, controls the rotation of the clamping assembly to drive the drinking water bucket to rotate, and further rotates the water outlet valve of the drinking water bucket.

[0041] S120, controlling the clamping mechanism to stop rotating after sensing the water outlet valve of the drinking water bucket through the sensing mechanism.

[0042] Among them, the sensing mechanism and the clamping mechanism are linked together. When the sensing mechanism senses the position of the water outlet valve of the drinking water bucket, the clamping mechanism is controlled to stop rotating, so that the drinking water bucket stops rotating, and then the position of the water outlet valve of the drinking water bucket is located.

[0043] S130, calibrating the position of the water outlet valve of the drinking water bucket through the water outlet valve positioning mechanism, so that the water outlet valve of the drinking water bucket and the spray washing mechanism are aligned.

[0044] Among them, when the water bucket stops rotating, the water outlet valve positioning mechanism is controlled to approach the conveying mechanism and clamp the water bucket, and then the position of the water outlet valve of the water bucket is calibrated, so that the water outlet valve of the water bucket and the spray cleaning mechanism can be accurately aligned, further improving the cleaning effect of the water outlet valve of the water bucket.

[0045] S140, controlling the spraying mechanism to rinse the outside of the water outlet valve of the drinking water bucket.

[0046] Among them, when the water outlet valve of the drinking water bucket and the spray cleaning mechanism are accurately aligned, the water outlet valve positioning mechanism is controlled to move away from the conveying mechanism, and then the spray cleaning mechanism flushes the outside of the water outlet valve of the drinking water bucket to effectively clean the outside of the water outlet valve of the drinking water bucket.

[0047] S150, controlling the valve opening mechanism to abut against the valve opening handle of the water outlet valve of the drinking water bucket, and controlling the spraying mechanism to flush the inside of the water outlet valve of the drinking water bucket.

[0048] Among them, when the spraying mechanism has finished cleaning the outside of the water outlet valve of the drinking bucket, the valve opening mechanism is controlled to approach the conveying mechanism and abut against the valve opening handle of the water outlet valve of the drinking bucket to make the water outlet valve of the drinking bucket open, and the spraying mechanism is controlled again to flush the inside of the water outlet valve of the drinking bucket to effectively clean the inside of the water outlet valve of the drinking bucket.

[0049] Please combine Figure 7 , Figure 7 A schematic flow chart of the sub-steps in step 130 of the method for positioning and cleaning the water outlet valve of a drinking water barrel provided by the present invention is shown.

[0050] In step S130, calibrating the position of the water outlet valve of the drinking water bucket by the water outlet valve positioning mechanism also includes the following sub-steps: S131, controlling the positioning drive assembly to respectively drive the first positioning assembly and the second positioning assembly to approach and clamp the drinking water bucket, so as to drive the calibration groove of the calibration plate to be clamped to the water outlet valve of the drinking water bucket; S132, controlling the positioning drive assembly to respectively drive the first positioning assembly and the second positioning assembly to loosen and move away from the water bucket, thereby releasing the clamping state of the calibration groove of the calibration plate, so that the water outlet valve of the water bucket can be pre-positioned.

[0051] In some embodiments, when the positioning drive assembly respectively drives the first positioning assembly and the second positioning assembly to approach and clamp the drinking water bucket, the calibration groove of the calibration plate connected to the first positioning plate close to the conveying mechanism is clamped on the water outlet valve of the drinking water bucket to position the water outlet valve of the drinking water bucket, thereby enabling the water outlet valve of the drinking water bucket and the spraying mechanism to achieve precise positioning; after the positioning is completed, the positioning drive assembly again drives the first positioning assembly and the second positioning assembly to loosen and move away from the drinking water bucket, and the calibration groove is released from the state of being clamped on the water outlet valve of the drinking water bucket, so that the water outlet valve of the drinking water bucket and the spraying structure are pre-positioned, which facilitates the spraying mechanism to clean the outside of the water outlet valve of the drinking water bucket.

[0052] In step S150, while controlling the valve opening mechanism to abut against the valve opening handle of the water outlet valve of the drinking water bucket, it also includes: The control positioning drive assembly drives the first positioning assembly and the second positioning assembly to approach and clamp the water bucket respectively. The first positioning plate clamps the water bucket and drives the calibration groove of the calibration plate to be clamped on the water outlet valve of the water bucket.

[0053] In some embodiments, the positioning drive assembly respectively drives the first positioning assembly and the second positioning assembly to approach and clamp the drinking water bucket. The first positioning plate moves and then drives the calibration plate and the valve opening plate of the valve opening mechanism to move, so that the calibration groove is clamped on the drinking water bucket water outlet valve, and the valve opening plate abuts against the valve opening handle of the drinking water bucket water outlet valve. When the drinking water bucket water outlet valve is opened, the position of the drinking water bucket water outlet valve is fixed and positioned, thereby avoiding the problem that the position of the drinking water bucket water outlet valve is offset due to the force exerted when the valve opening plate abuts, thereby improving the cleaning effectiveness of the drinking water bucket water outlet valve.

[0054] In some preferred embodiments, when the calibration groove is clamped to the water outlet valve of the drinking bucket, the positioning groove of the first positioning plate is clamped to the outer periphery of the drinking bucket, thereby ensuring the stability of the first positioning plate when clamping the drinking bucket, thereby ensuring the stability of the calibration groove clamped to the water outlet valve of the drinking bucket, improving the reliability during pre-positioning and / or cleaning the inside of the water outlet valve of the drinking bucket, and improving the compactness of the overall structure.

[0055] In step S110, before the drinking water bucket is clamped by the clamping mechanism and rotated, the method further includes: The water bucket is stopped by the blocking bucket mechanism, and the conveying mechanism is controlled to stop conveying; Control the lifting drive member to drive the clamping assembly to approach the conveying mechanism and clamp the drinking water bucket; The lifting drive member is controlled to drive the clamping assembly away from the conveying mechanism.

[0056] In some embodiments, the conveying mechanism and the barrel-blocking mechanism are arranged in linkage, and the conveying mechanism conveys the drinking water barrel whose water outlet valve is to be cleaned. When the external sensor senses that the number of drinking water barrels on the conveying mechanism has reached a preset number, the barrel-blocking mechanism stops the drinking water barrel, and the conveying mechanism stops conveying at the same time; the lifting drive member of the clamping mechanism drives the clamping assembly to approach the conveying mechanism and clamp the drinking water barrel, and then the lifting drive member drives the clamping assembly away from the conveying mechanism again, thereby driving the drinking water barrel away from the conveying mechanism, making it easier for the clamping assembly to drive the drinking water barrel to rotate, thereby improving the reliability of the sensing mechanism in sensing the water outlet valve of the drinking water barrel.

[0057] The positioning and cleaning device and positioning and cleaning method of the water outlet valve of the drinking water bucket of the present invention, because the first positioning component synchronously calibrates the position of the water outlet valve of the drinking water bucket when approaching the conveying mechanism and clamping the drinking water bucket, it ensures that the water outlet valve of the drinking water bucket and the spray cleaning mechanism are accurately aligned; and because the valve opening plate of the valve opening mechanism is connected to the side of the first positioning component close to the conveying mechanism, when the first positioning component approaches the conveying mechanism and clamps the drinking water bucket, it will drive the valve opening plate to abut against the valve opening handle of the water outlet valve of the drinking water bucket, so that the water outlet valve of the drinking water bucket is in an open state, which is convenient for the spray cleaning mechanism to clean the inside of the water outlet valve of the drinking water bucket; in this way, not only the problem of easy deviation in positioning between the water outlet valve of the drinking water bucket and the nozzle of the spray cleaning mechanism is solved, but also the problem of inadequate cleaning of the water outlet valve of the drinking water bucket is solved.
