Description

Technical Field

[0001] The invention relates to the technical field of soft bag quality detection, and in particular to a multifunctional soft bag quality detection device. Background Art

[0002] During the production process, soft bag infusion products will be quality inspected based on the product characteristics in different places. Testing equipment will be used when testing the products to confirm whether the quality of the products meets the control requirements.

[0003] Patent CN113447217A discloses a sealing inspection unit for a soft bag packaging system, including a detection tank, a vacuum pump, a top cover, a pressure sensor, a pressure gauge and an alarm system, wherein the vacuum pump is arranged on one side of the detection tank, the top cover is arranged on the top of the detection tank, the pressure gauge is fixed on one side of the detection tank, and the pressure gauge is connected to the pressure sensor, an installation groove is opened on the inner wall of one side of the detection tank, and the pressure sensor is installed in the installation groove, and a disassembly structure is provided between the detection tank and the pressure sensor; by adding an alarm system to the sealing inspection unit of the soft bag packaging system, when the soft packaging bag under inspection has a sealing defect, the alarm system will automatically start the alarm light to remind the operator, so that the operator does not need to repeatedly compare the values ​​on the pressure gauge during daily inspection, and only needs to observe whether the alarm light is on to determine whether the soft packaging bag under inspection has a sealing defect.

[0004] The soft bag detection device disclosed in the above patent only realizes an alarm reminder, and the above detection device can only realize the internal pressure detection function, which has great limitations in the quality detection of soft bags.

[0005] Current soft bag detection devices include: Figure 1 The structure shown in the figure is mainly used for the detection of soft bag welding. First, put the controlled infusion bag on the platform, then remove the valve sheet on the interface of the infusion bag, put the other end of the detection pressure gauge into the infusion bag, and then start the cylinder. The air source is provided by the cylinder action and the original position air path, so that the pressure plate installed on the cylinder is pressed on the infusion bag. During this squeezing process, pressure will be generated. When the generated pressure acts on the pressure gauge and is displayed, it is maintained for a certain time, and then the infusion bag is taken out to observe whether there is any abnormality at each welding point. If there is no abnormality, it means it is qualified.

[0006] The cylinder in the detection device has an original and actuating air path interface, but the pressure of the driving air source is not controlled. If the compressed air fluctuates, the detection will be inaccurate. In addition, there is no guide device during the cylinder driving process, and there will be misalignment when waiting for action, which will cause fluctuations in the detection data. The detection device is also unable to detect the data for starting timing and cannot accurately determine the detection time. Summary of the invention

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions 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. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0042] The following detailed description specifically discloses the embodiments of the present application with appropriate reference to the drawings. However, there may be cases where unnecessary detailed descriptions are omitted. For example, there may be cases where detailed descriptions of well-known matters and repeated descriptions of actually the same structures are omitted. This is to avoid the following description from becoming unnecessarily lengthy and to facilitate the understanding of those skilled in the art. In addition, the drawings and the following description are provided for those skilled in the art to fully understand the present application and are not intended to limit the subject matter described in the claims.

[0043] The "range" disclosed in this application is defined in the form of a lower limit and an upper limit, and a given range is defined by selecting a lower limit and an upper limit, and the selected lower limit and upper limit define the boundaries of the particular range.

Therefore, the features defined as "number one" and "number two" may explicitly or implicitly include at least one of the features.

[0045] Unless otherwise specified, all embodiments and optional embodiments of the present application can be combined with each other to form a new technical solution.

[0046] Unless otherwise specified, all technical features and optional technical features of this application can be combined with each other to form a new technical solution.

[0047] Unless otherwise specified, the terms "include" and "comprising" mentioned in this application may be open-ended or closed-ended. For example, the terms "include" and "comprising" may mean that other substances not listed may also be included or only the listed substances may be included.

[0048] like Figure 1 As shown, it is a structural schematic diagram of the detection device of the soft bag infusion product in the prior art, and its working principle is as follows: this device is mainly used for the detection of the welding of the infusion bag 4. First, the prepared infusion bag 4 is placed on the platform, and then the valve sheet on the interface of the infusion bag 4 is removed, and the other end of the detection pressure gauge 3 is placed in the infusion bag 4, and then the cylinder 1 is started. The air source is provided by the action of the cylinder 1 and the original position air path, so that the pressure plate 2 installed on the cylinder 1 is pressed on the infusion bag 4. During this squeezing process, pressure will be generated, and the generated pressure will act on the pressure gauge 3 for display. After maintaining for a certain period of time, the infusion bag 4 will be taken out to observe whether there is any abnormality at each welding point. If there is no abnormality, it means that it is qualified.

[0049] As can be seen from the figure, in the current method, cylinder 1 has an original air path interface with the action position, but the pressure of the driving air source is not controlled. If the compressed air fluctuates, the detection will be inaccurate.

[0050] There is no guide device during the driving process of cylinder 1, and there will be misalignment problems when it is in motion, which will cause fluctuations in the detection data.

[0051] There is no test start timing data, so the test time cannot be accurately determined.

[0052] Based on this, the present application provides a multifunctional soft bag quality inspection device, which has four major functional areas and a centralized operation control area, and can perform comprehensive inspections on the infusion bags 4 during the production process, ensuring that the quality of the products produced is stable and reliable, and can automatically record its data, and can automatically complete storage and protection, thereby improving the quality control of the soft bag production process, while also improving the inspection efficiency, and being able to adapt to the quality inspection of soft bag products of different specifications.

[0053] Example 1

[0054] like Figures 2 to 6 As shown, this embodiment provides a multifunctional soft bag quality detection device, including an operation function host computer 5 installed on the device body, a soft bag internal pressure detection unit 6, a soft bag empty bag detection unit 7, a soft bag immersion detection unit 9 and a soft bag high-rise drop detection unit 10; the device body is connected to a pressure detector;

[0055] The soft bag internal pressure detection unit 6 comprises a first pressure-bearing plate 18 connected to the device body, and a first extrusion structure is installed directly above the first pressure-bearing plate 18;

[0056] The soft bag empty bag detection unit 7 includes a second extrusion structure connected below the first pressure plate 18, and a second pressure plate 24 is connected to the device body directly below the second extrusion structure;

[0057] The soft bag water immersion detection unit includes a mounting plate 25 connected to the device body, the mounting plate 25 is connected to a third extrusion structure, a third pressure plate 51 is installed directly below the third extrusion structure, and the third pressure plate 51 is connected to a water injection structure and a drainage structure;

[0058] The soft bag high drop unit includes a platform connected to the bottom of the device body.

[0059] Specifically, two pressure detectors are installed in this embodiment, including a first pressure detector 15 installed above the device body, and the first pressure detector 15 is used for the pressure values ​​of the soft bag internal pressure detection unit 6 and the soft bag empty bag detection unit 7. The first pressure detector 15 is connected to the main pipe 43, and the main pipe 43 is divided into two branches 42, which are respectively used to connect the soft bags of the soft bag internal pressure detection unit 6 and the soft bag empty bag detection unit 7. A second pressure detector 50 is connected to the lower part of the device body, and the second pressure detector 50 is connected to the soft bag through a pipe when the soft bag immersion detection unit 9 is detected. The pressure sensor is provided with two sets of control switches, which can save the instrument cost and the operation procedure is also simpler.

[0060] The soft bag empty bag detection unit 7 is connected with an inflation pipeline 41 , an inflation pressure sensor is connected to the inflation pipeline 41 , and an exhaust port is also provided on the inflation pipeline 41 .

[0061] Specifically, the first extrusion structure includes a first driving cylinder 11, a first driving booster plate 17 is connected to the movable rod of the first driving cylinder 11, and a first driving booster plate 17 guide structure is installed on both sides of the first driving booster plate 17. The first driving booster plate 17 guide structure includes a first guide rail 44 installed on the device body, and first moving blocks 45 slidably connected to the first guide rail 44 are connected on both sides of the first driving booster plate 17. The action air circuit interface 12 of the first driving cylinder 11 is connected to the first pressure regulating valve 13, and the original position air circuit interface 16 of the first driving cylinder 11 is connected to the first start switch 14.

[0062] Among them, the main function of the soft bag internal pressure detection unit 6 is to detect the infusion bag 4 after it is filled with liquid medicine. First, the infusion bag 4 to be detected is placed on the first pressure-bearing plate 18, and then the valve plate on the tube mouth of the infusion bag 4 is removed, and the pressure detection hollow probe is inserted into the bag from the tube mouth of the infusion bag. The probe will be sealed by the rubber plug in the tube mouth of the infusion bag 4 and will not leak; after preparation, turn on the start switch, the first cylinder starts to enter, and the air outlet starts to move, driving the first drive booster plate 17 downward. When it is completely pressed on the infusion bag 4, the pressure is adjusted through the first pressure regulating valve 13 according to the detection pressure value range set on the operating function host computer 5. When the pressure is adjusted to the specified standard value, the system will automatically time. When it is maintained for the specified standard time, the system will automatically reset and issue a "successful detection" voice alarm. On the contrary, if the detection fails, there will be an alarm prompt of detection failure.

[0063] During the detection, one end of the first pressure detector 15 is inserted into the bag through the tube opening of the infusion bag 4. When started, the first pressure plate is driven to exert force on the infusion bag 4 to form a pressure difference, which is detected by the pressure sensor and the signal is uploaded to the operating function host computer 5. The operating function host computer 5 will display the current pressure. When the set data value is reached, the system automatically starts timing. When the specified detection time is reached, the system automatically shuts down and resets.

[0064] The guide structure of the first driving booster plate 17 in the soft bag empty bag detection unit 7 can quickly improve the accuracy of the first driving booster plate 17 when it is in motion or reset, without shaking, and also improve the detection efficiency.

[0065] The action air path of the first driving cylinder 11 is connected to the first pressure regulating valve 13, so that the device can adjust the action speed of the first driving cylinder 11 according to the usage situation, further increasing the action stability.

[0066] The first driving booster plate 17 is surface treated to be flat and smooth, so it will not cause damage to the infusion bag 4 during the detection process, further improving its stability.

[0067] The soft bag internal pressure detection unit 6 of the device can be turned on by the first start switch 14, and the detection device can work normally after being turned on. At the same time, it can also be quickly detected by operating the one-key start on the upper computer 5.

[0068] The soft bag internal pressure detection unit 6 of the device has the following advantages:

[0069] 1. The guide structures added on both sides of the first driving boost plate 17 can quickly improve the accuracy of the first driving boost plate 17 when it is in motion or reset, and will not shake, which also improves the detection efficiency.

[0070] 2. The cylinder action air circuit and the boost throttle valve can adjust the cylinder action speed according to the usage conditions, further increasing the action stability.

[0071] 3. An external pressure regulating valve structure is added to the entire gas circuit to connect to the compressed air of the public system, which can accurately achieve primary adjustment of the pressure and stabilize the pressure to further improve its stability.

[0072] 4. The first driving booster plate 17 is surface treated to be flat and smooth, which will not cause damage to the infusion bag 4 during the detection process, further improving its stability.

[0073] 5. Use a precise pressure sensor. When testing is needed, insert one end of the pressure sensor into the bag through the tube opening of the infusion bag 4. After starting, the force of the driving booster plate acts on the infusion bag 4 to form a pressure difference, which is detected by the pressure sensor and the signal is uploaded to the operating function host computer 5. The operating function host computer 5 will display the current pressure. When the set data value is reached, the system will automatically start timing. When the specified detection time is reached, the system will automatically shut down and reset.

[0074] 6. The pressure detection sensor uses two sets of control switches. When the function that needs to be detected is reached, the switch automatically switches to realize pressure detection, which can save instrument costs and make the operation procedure simpler.

[0075] 7. The first start switch 14 is used. After the infusion liquid to be tested is placed, the first start switch 14 can be turned on, and the detection device can work normally. At the same time, it can also be quickly tested through a one-button start on the host computer.

[0076] 8. The cylinder, solenoid valve, quick-close, pressure sensor, etc. used in the entire detection device can be customized, which can better meet the different detection requirements of various industries, and its accuracy can be controlled between 0.01bar.

[0077] 9. In order to ensure the safety of the entire process, an overpressure alarm or a low pressure alarm can be set on the operation function host computer 5, which intelligently reminds the operator of safe operation and pre-operation inspection to further improve safety.

[0078] Specifically, the second squeezing structure of the soft bag empty bag detection unit 7 includes a second driving cylinder 21, a second driving booster plate 39 is connected to the movable rod of the second driving cylinder 21, and a second driving booster plate 39 guide structure is installed on both sides of the second driving booster plate 39. The second driving booster plate 39 guide structure includes a second guide track installed on the device body, and second moving blocks slidably connected to the second guide track are connected on both sides of the second driving booster plate 39. The action air circuit interface 22 of the second driving cylinder 21 is connected to the second pressure regulating valve 20, and the original position air circuit interface 23 of the second driving cylinder 21 is connected to the second start switch 19.

[0079] The structural schematic diagram of the guide structure of the second driving boost plate 39 is the same as the structural schematic diagram of the guide structure of the first driving boost plate 17 .

[0080] The main function of the software empty bag detection unit is to detect the prepared infusion bag 4. During the specific detection, the infusion bag 4 to be detected is first placed on the second pressure plate 24, and then the valve plate on the tube mouth of the infusion bag 4 is removed, and the pressure detection hollow probe is inserted into the bag from the tube mouth of the infusion bag. The probe will be sealed by the rubber plug in the tube mouth of the infusion bag 4 and will not leak. After preparation, turn on the second starting switch 19, the second driving cylinder 21 starts to enter, and the air outlet starts to move, driving the second driving booster plate 39 forward. When driven to the set spacing, the second driving cylinder 21 maintains the current stroke, and then inserts the inflation pipeline 41 from the air outlet of the infusion bag 4. After starting, the device works under the set parameters. When the set parameters are reached, the device performs detection and maintenance. After reaching the detection, the system automatically switches to close, and at the same time, the excess air in the bag is discharged from the exhaust port, and the infusion bag 4 is taken out, and the infusion can be further observed for damage.

[0081] The soft bag empty bag detection unit 7 has the following advantages:

[0082] 1. The soft bag empty bag detection unit 7 not only has all the advantages of infusion bag 4 detection, but also has the main feature of being able to detect the manufactured empty infusion bag 4 in advance, and more accurately determine whether the welding quality of the infusion bag 4 is stable before the infusion bag 4 is filled with liquid medicine. If the system detects that the pressure cannot be maintained, it will alarm, indicating that the infusion bag 4 is unqualified, and the problem can be found intuitively and quickly, which greatly improves the detection rate.

[0083] 2. Its main advantage is that after the infusion bag 4 is inflated, it can automatically switch and complete the detection according to the set parameters. After the detection, the system automatically switches and discharges the air in the bag, which can meet the detection of infusion bags 4 of different specifications and types.

[0084] 3. Since the compressed air filled in is filtered by the system, the exhaust will not cause pollution to the production environment.

[0085] 4. The entire test data will be recorded by the host computer, and reports can be automatically generated according to the recording requirements.

[0086] Specifically, the third extrusion structure of the soft bag immersion detection unit 9 includes a third driving cylinder 28, a third driving booster plate 34 is connected to the movable rod of the third driving cylinder 28, and a third driving booster plate 34 guide structure is installed on both sides of the third driving booster plate 34. The third driving booster plate 34 guide structure includes a cross bar 31 connected to the device body, a guide sleeve 32 is connected to the cross bar 31, a linear guide rod 33 is connected inside the guide sleeve 32, and the lower end of the linear guide rod 33 is connected to the third driving booster plate 34. The action air circuit interface 3 29 of the third driving cylinder 28 is connected to the third pressure regulating valve 27, and the original position air circuit interface 3 30 of the third driving cylinder 28 is connected to the third start switch 26. The soft bag immersion detection unit also includes a liquid level detection sensor 40 for detecting the liquid level in the soft bag immersion detection unit area.

[0087] Specifically, the water injection structure includes a water injection pipe 36 connected to the third pressure plate 51 , and the water injection pipe 36 is connected to a water injection pneumatic valve 35 ; the drainage structure includes a drainage pipe 38 connected to the third pressure plate 51 , and the drainage pipe 38 is connected to a drainage pneumatic valve 37 .

[0088] The soft bag immersion detection unit 9 is mainly used for experiments or troubleshooting of complex problems. Its working principle is: the infusion bag 4 to be tested is placed on the third pressure plate 51, and the third driving cylinder 28 is activated first to make the third driving booster plate 34 move downward. When the set distance is reached, it remains unchanged. At this time, the inflation tube is inserted through the interface of the infusion bag 4, and the start button is pressed again. At this time, the infusion bag 4 begins to be inflated according to the set parameters, and is closed after the set time is filled. At this time, the system enters the next step, the water injection pneumatic valve 35 is opened, and water is injected into the working area. When the water injection amount is detected by the liquid level sensor for the experiment, the water injection start valve is closed, and the system maintains the current pressure. Confirm within the specified parameter time whether the pressure will drop and whether there are bubbles in the water. Double-check whether the infusion bag 4 meets the requirements under the specified conditions. After the requirements are met, the system automatically resets. At the same time, the infusion bag 4 can be taken out and observed and confirmed again. All detection data are recorded and saved.

[0089] The soft bag immersion detection unit 9 has the following advantages:

[0090] 1. It can not only be used for the detection of infusion bags 4 and infusion medicine bags, but also the detection process is more intuitive and more stable.

[0091] 2. The water used in the device is process water that meets the requirements for production and will not cause pollution or impact on the production process.

[0092] 3. In order to prevent the pressure plate from rusting due to contact with water for a long time, high-quality stainless steel is used. When the linear guide rod 33 and the guide sleeve 32 are used together for a long time, they will not deform or rust, and are not prone to wear.

[0093] 4. The entire test area is a closed space. The infusion bag 4 is placed through the observation window 47. There is enough space and it will not affect the operation of placing the infusion bag 4. After the product is placed, the observation window 47 is completely closed and no water vapor will leak out. Because it is in a closed state, if an abnormality occurs and the bag leaks sideways, water will not spray on the staff.

[0094] 5. Connect the liquid level detection sensor 40. When the liquid reaches the set value, it will automatically close. When the liquid level is not enough, it will automatically start to replenish water, making the operation simpler. Similarly, when detection is not needed, the system will automatically open the drainage pneumatic valve 37 to drain the water. The drainage pneumatic valve 37 has a blocking function, so the drained water will not flow back, reducing pollution to keep the site clean.

[0095] 6. The pressure during testing can be adjusted and stabilized in real time.

[0096] 7. The corresponding test data can be set and the recipe management can be performed on the human-machine interface.
