Description

Technical Field

[0001] The utility model relates to the technical field of quality detection of daily chemical product bottles, in particular to a quality detection device for daily chemical product bottles. Background Art

[0002] With the advancement of science and technology, the daily chemical industry has seen rapid growth, with both types and quantities increasing dramatically. For liquid daily chemical products like disinfectants, the production process typically begins by filling the liquid into high-density polyethylene (HDPE) bottles. Then, a cap containing an aluminum foil gasket is tightened onto the filled bottle. Electromagnetic heat is used to melt the adhesive layer of the foil gasket, creating a beautiful and secure seal around the bottle opening. If the foil seal is not adequate, the daily chemical product will leak, impacting both product quality and shelf life. Therefore, testing the seal of the aluminum foil around the bottle opening is particularly important. In addition to testing the seal, the inkjet printing status of the bottle body is also an important inspection item.

[0003] Specifically, there are several methods for quality inspection of daily chemical bottles:

[0004] 1) Existing sealing detection technology methods

[0005] The Chinese utility model patent, patent number CN201910721112.9, the patent name is daily chemical bottle aluminum foil sealing detection device and detection method, the detection device includes a linear module drive mechanism, a table, and a pressure measuring mechanism; the linear module drive mechanism is installed on the table; during the detection, for the daily chemical bottle that has completed the aluminum foil sealing production, the bottle cap is unscrewed, and a certain amount of extrusion is applied to its circumference radially, and the air in the bottle is squeezed. If the daily chemical bottle aluminum foil sealing is good, the reaction force of the daily chemical bottle resisting deformation will be greater than a certain critical value, and this critical value is defined as the threshold value; if the daily chemical bottle aluminum foil sealing is not good, the air in the bottle will be squeezed and leaked, and the reaction force of the daily chemical bottle resisting deformation will be less than this critical value, and the daily chemical bottle aluminum foil sealing is judged accordingly.

[0006] Although the utility model has a reasonable design, is easy to operate, and can reliably detect the sealing properties of aluminum foil on daily chemical bottles of various specifications, it still has certain design flaws: during the actual extrusion process, the linear module drive mechanism and the pressure measuring mechanism will simultaneously squeeze a single daily chemical bottle to obtain a reaction force. During the detection process, the right guide pressure rod of the structure provides a certain driving force and extrusion feed amount through the linear module. During the detection, the compression spring of the left guide pressure rod will produce a certain movement. This situation will cause the daily chemical bottle to move along the feed direction of the right guide pressure rod, further causing the position of the daily chemical bottle to change unpredictably. At the same time, because the left and right guide pressure rods squeeze the daily chemical bottle at the same time, the daily chemical bottle is subjected to extrusion forces from both sides. Because the position of the daily chemical bottle changes dynamically during the test, and the daily chemical bottle is subjected to extrusion forces from both sides, the force on both ends of the daily chemical bottle will be uneven. For example, when the same daily chemical bottle with a sealing defect is tested multiple times, the reaction force obtained will vary over a large range, the test data will be inaccurate, and the results will have large deviations.

[0007] The patent uses a threshold method to determine the sealability of aluminum foil on daily chemical bottles. Different thresholds are generated based on the extrusion speed and the amount of extrusion applied to the bottle. In the actual testing process, the testing equipment will test the same or different types of daily chemical bottles at different extrusion speeds and amounts, taking into account the production efficiency and different types of daily chemical bottles. This method increases equipment commissioning time, reduces testing efficiency, and affects the production efficiency of daily chemical bottles.

[0008] 2) Existing bottle bottom coding quality inspection technology

[0009] In a specific bottle bottom coding quality inspection device, such as Figure 11 As shown, the bottle-gripping conveyor mechanism and image acquisition assembly are integrated into a single structure, mounted on the main frame of the image acquisition assembly. As bottles are transported along the conveyor line to the bottom-coding image quality inspection station, dual blocking cylinders operate in tandem to ensure only a single bottle enters. Driven by the bottle-gripping conveyor mechanism, the bottles reach the quality inspection station. A sensor receives a signal, triggering a camera to capture the image and transmitting it to an industrial control tablet. The tablet runs an image processing program, outputting the recognition result to the camera. The camera then transmits a signal to the PLC controller, which in turn issues a command to the reject cylinder, which activates and removes unqualified bottles to a collection bin.

[0010] Although this structure successfully realizes the rejection of defective products, the detection process of this mechanism uses multiple execution structures to work together to allow a single daily chemical product bottle to enter the inspection, and the detection efficiency of this detection method is low.

[0011] 3) Existing daily chemical bottle quality testing equipment

[0012] like Figure 12 As shown, the bottle cap loosening and capping machine is used to loosen the caps of daily chemical bottles; the conveying component is used to convey daily chemical bottles; the detection and rejection component is used to apply a certain amount of extrusion in the circumferential radial direction to the daily chemical bottles that have completed the aluminum foil sealing production, and detect whether the reaction force value of the daily chemical bottles resisting deformation is within the threshold range. The daily chemical bottles with reaction force values lower than the threshold are rejected into the collection box, and the daily chemical bottles with reaction force values that meet the threshold are sent to the next station; the bottle cap tightening and capping machine is used to tighten the caps of the daily chemical bottles that are judged to be good after the aluminum foil seal test. This equipment mainly completes the separate aluminum foil seal detection operation; and this detection equipment is based on the detection after the finished product, and the bottle cap needs to be unscrewed before the detection and needs to be tightened again after the detection, which increases the operation process.

[0013] In summary, existing testing equipment can only separately test the aluminum foil sealing and bottle bottom coding quality of daily chemical bottles, and cannot realize the testing of aluminum foil sealing and bottle bottom coding quality in the same equipment; existing testing methods have certain problems of inaccurate test results and low efficiency; in addition, when testing finished products, continuous large quantities of defective products may appear in the actual production process, and the production process cannot be stopped in time to stop losses, which further increases the production costs of the enterprise.

[0014] Therefore, how to develop an integrated daily chemical bottle quality inspection device that can perform multiple inspections with one device and quickly eliminate defective products has become a technical problem that needs to be solved urgently by those skilled in the art.

During operation, after qualified daily chemical product bottles are delivered to the station via the turntable, the unloading cylinder 501 activates its telescopic rod to extend, and pushes the daily chemical product bottles onto the unloading conveyor belt 4 through the unloading push plate, and transmits them to the finished product box or the next process.

[0067] Specifically, such as Figure 5 As shown, the loading conveyor belt 3 and the unloading conveyor belt 4 have the same structure but different conveying directions. The loading conveyor belt 3 drives the daily chemical product bottles to be inspected from the outside to the inside to the turntable 5, and the unloading conveyor belt 4 drives the daily chemical product bottles that have completed inspection from the inside to the outside to the end away from the turntable 5; the structures of the loading conveyor belt 3 and the unloading conveyor belt 4 both include a support frame, a drive motor, a conveyor belt and two parallel transmission wheels.

[0070] In another embodiment, two defective product rejection stations 400 can be provided, which are respectively located behind the sealing inspection station 200 and the coding inspection station 300, that is, the turntable 5 has six stations arranged in sequence along the outer circumference to complete the rejection operation of defective products in a single inspection, which is more classified and targeted.

[0071] like Figure 5 As shown, the defective product rejection station 400 is located on the side opposite to the loading station 100, and includes a rejection cylinder 401 and a waste table 403 for holding unqualified daily chemical product bottles. The waste table 403 is placed on the outside of the frame 1, and the rejection cylinder 401 is installed on the top steel frame of the frame 1 through the first cylinder mounting frame 402, and the rejection cylinder 401 is located above the turntable 5.

During operation, the controller receives the detection signal and sends it to the pressure sensor 207 at the sealing detection station 200 and the detection signal of the industrial camera 302 at the inkjet detection station 300. When any of the stations judges it as a defective product, the unqualified daily chemical product bottle is pushed to the defective product rejection station 400 through the turntable, the rejection cylinder 401 is started, and the telescopic rod of the rejection cylinder 401 is extended to push the unqualified daily chemical product bottle onto the waste table 403.

[0074] During operation, the two baffles 606 cooperate to form a self-resetting door opening and closing structure. The hinge axis forms the rotation point, and the baffles and hinges are connected to form a revolving pair. The baffles 606 rotate around the hinge axis to open or close. The connecting rod 604, slider 603, guide rail 607, and second spring 602 together form a reset drive structure, providing the driving force for the reset and closure of the baffles 606. This structural design can prevent the daily chemical product bottles from falling out of the positioning grooves of the turntable due to centrifugal force when they are in the defective product rejection station 400 and the unloading station 500 during the rotation of the turntable.

A light source 303 is provided on the periphery of the industrial camera 302, and the light source 303 is installed on the top plate 1-1 of the frame 1 through a light source bracket 301.

[0077] In addition, it also includes a controller, which is arranged in a cavity at the bottom of the frame 1, and corresponding operation buttons or LCD screens are arranged on the outside to form an automated control system; among them, the loading cylinder 101, the unloading cylinder 501, the pressure sensor 207, the industrial camera 302, the rejection cylinder 401 and the driving motor of the conveyor belt are all electrically connected to the controller to realize signal transmission, thereby realizing automated operation and saving time and effort.

[0078] like Figure 10 As shown, a method for detecting the quality of daily chemical bottles comprises the following steps:

[0079] Step 1: Loading: The daily chemical product bottles to be tested are transported to the loading station 100 via the loading conveyor belt 3, and the loading cylinder 101 is activated to push the daily chemical product bottles to be tested into the positioning groove of the turntable 5;

[0080] The turntable 5 starts and rotates a certain angle to deliver the daily chemical product bottle to be inspected to the second station; the second station is the sealing inspection station 200 or the coding inspection station 300;

[0081] Step 2: Inspection operation: including a sealing inspection station 200 or a coding inspection station 300, which are arranged adjacent to each other or spaced apart. The sealing inspection station 200 performs sealing inspection on the daily chemical product bottles, and the coding inspection station 300 performs coding quality inspection on the daily chemical product bottles;

[0082] After the inspection is completed, the turntable 5 starts and rotates a certain angle to deliver the inspected daily chemical product bottles to the next station;

[0083] Step 3: Rejection of defective products: After the inspection, the daily chemical product bottles arrive at any one of the defective product rejection stations 400. The rejection cylinder 401 is activated based on the inspection result of whether the daily chemical product bottles have quality defects and pushes the daily chemical product bottles with quality defects to the waste platform 403 on the side.

[0084] The turntable 5 starts and rotates a certain angle to deliver the daily chemical product bottles without quality problems directly to the next station. When the daily chemical product bottles without quality problems pass through the defective product rejection station 400, the rejection cylinder 401 does not move;

[0085] Step 4, unloading operation: When the daily chemical product bottles without quality problems arrive at the unloading station 500, the unloading cylinder 501 is started to push the daily chemical product bottles without quality problems to the unloading conveyor belt 4 for output.

[0086] Specifically, during implementation, the multi-station integrated daily chemical product bottle quality detection device is installed at the corresponding position of the production line, which can realize online rapid detection of the quality of daily chemical product bottles.

[0087] Specifically, in step 2, the sealing detection station 200 is an extrusion detection component driven by a linear motor 201. The structure is similar to that in the existing paper, which is titled "Seal Testing Method and Experimental Research on Aluminum Foil Seal Testing of Daily Chemical Bottles" [J]. Packaging Engineering, 2022, 43(21): 206-212. It can be seen from the air leakage model that this method is compared with the current seal testing method of aluminum foil for daily chemical bottles: in the actual testing process, considering the production efficiency of daily chemical bottles and the different types of daily chemical bottles, the testing equipment will test the same or different types of daily chemical bottles at different extrusion speeds and extrusion amounts. There is no need to manually change the threshold. The leakage area is directly obtained through the model, and the sealing of the daily chemical bottle is judged by the leakage area. This sealing testing method reduces the time for equipment debugging, improves the testing efficiency, and further helps to improve the production efficiency of daily chemical bottles.

[0088] In general, the utility model adopts a turntable layout, and multiple workstations work in parallel, which can greatly improve production efficiency; and the layout is compact, the integration is high, and the space occupied is small; the degree of automation is high, the operation saves time and effort, and the equipment detection effectively reduces the intensity of manual detection and improves the detection accuracy; the integrated design realizes the detection of two or even more contents of sealing and coding, with a higher degree of automation and lower production cost; at the same time, the device is assembled to the appropriate position of the production line, and quality inspection is carried out during the production process of daily chemical bottles. The number and frequency of defective products can be monitored in real time to prevent the continuous large-scale production of defective products during the production process, further reducing the production cost of the enterprise, and being more conducive to protecting the environment.
