Description

Technical Field

[0001] The utility model relates to the technical field of packaging detection, in particular to an automatic packaging detection device for strip-packaged creatine powder. Background Art

[0002] Creatine powder is usually packed in stick packaging bags, and non-rigid packaging bags such as plastic or aluminum foil are used. In order to extend the shelf life of creatine powder, protective gases such as nitrogen are also filled in the packaging bags. Of course, considering the space occupied by the gas in the package, if protective gas is to be filled, the appropriate amount of protective gas will be selected so as not to cause the packaging bag to expand too much.

Therefore, it is impossible to detect leaking creatine powder packaging bags by sampling inspection. Leaking creatine powder packaging bags will cause creatine powder to oxidize during the shelf life, or absorb moisture and agglomerate, eventually causing customer complaints. Utility Model Content

DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] Powdered products, especially food products, are packaged in small bags to meet people's needs for one-time use. The remaining products can still maintain a good seal, extending the shelf life of the product. For example, creatine powder is currently mainly divided into canned and bagged. Creatine powder is contained in strip packaging bags, and non-rigid packaging bags such as plastic or aluminum foil are used as containers. In order to extend the shelf life of creatine powder, protective gases such as nitrogen are also filled in the packaging bags. Of course, considering the space occupied by the gas in the package, if protective gas is to be filled, an appropriate amount of protective gas will be chosen that does not cause the packaging bag to expand too much. In this way, more creatine powder packaging bags can be contained in the same size packaging box, or the same number of creatine powder packaging bags can be packaged in a smaller packaging box.

[0033] The sealing of the creatine powder strips is automatically sealed by a specific device. It is inevitable that a small number of creatine powder bags will leak due to abnormal equipment debugging or other factors. Therefore, the sampling test method cannot ensure that 100% of the leaking creatine powder bags are detected. Leakage of creatine powder bags will cause the creatine powder to oxidize during the shelf life, or absorb moisture and agglomerate. If these creatine powders with quality abnormalities are not detected and reach customers, it will cause customer complaints.

[0034] At present, the sealing performance of the strip creatine powder packaging bag, or the strip product packaging bag, is tested by means of manual squeezing and depressurization in water. In this application, the strip creatine powder packaging bag is mainly used as an example for explanation, and the other strip packaging bags are also applicable.

[0035] The manual squeezing method is to select the strip creatine powder packaging bag to be tested, and judge whether the packaging bag is leaking by squeezing it by hand. For example, the pressure felt by the hand when squeezing the packaging bag, and whether the packaging bag maintains its volume without shrinking significantly, these characteristics can be used to judge whether the packaging bag is leaking. The manual squeezing method is subjective and inefficient to judge whether the packaging bag is leaking. It will also damage the appearance of the packaging bag. For example, wrinkles will remain on the surface of the packaging bag after squeezing, affecting sales. Therefore, the manual squeezing method cannot be applied to the full detection of strip creatine powder packaging bags.

[0036] The method of reducing pressure in water is to select the strip creatine powder packaging bag to be tested, place it in a container filled with water, and make the water cover the packaging bag, and then reduce the pressure of the container filled with water. If the packaging bag is not sealed well and there is air leakage, the gas in the packaging bag will overflow and produce a series of bubbles in the water. When bubbles are observed in the water, it can be proved that the packaging bag being tested is not sealed well and there is air leakage. Similarly, the method of reducing pressure in water also has the problem of low efficiency. At the same time, the packaging bag to be tested needs to be immersed in water, which will affect the appearance of the packaging bag, such as water stains.

[0037] The present application proposes an automatic packaging and detection device for creatine powder in bars to solve the above-mentioned problems.

[0038] Reference Figure 1 As shown, an automatic packaging and detection device for packaged creatine powder in one embodiment of the utility model includes a conveying component 100, a sealing component 200, a vacuum component 300 and a visual detection component 400.

[0039] The conveying assembly 100 is used to convey the product to be tested. The conveying assembly 100 is provided with a testing area, and all products can pass through the testing area. The products to be tested include various packaging bags. In this application, the packaging bag of creatine powder in strips is used as an example for explanation. The testing area is an area planned on the conveying assembly 100, and the area can be virtual. Therefore, the conveying assembly 100 transports the product to the testing area without additional transportation. For example, there is no need to transport the product from the conveying assembly 100 to other testing equipment.

[0040] The sealing component 200 has a switchable first state position and a second state position. In the first state position, the sealing component 200 encloses the detection area to form a closed space. In the second state position, the sealing component 200 avoids the conveying component 100. The sealing component 200 provides a special environment for the detection area, specifically, a low-pressure environment in the detection area. In addition, when no detection is performed, the sealing component 200 cannot affect the normal transportation of the conveying component 100, so the sealing component 200 needs to have two state positions. When the product is tested for sealing, the sealing component 200 works in the first state position. When no detection is performed, the conveying component 100 is conveying the product, and the sealing component 200 works in the second state position.

[0041] The exhaust component 300 is connected to the sealing component 200. When the sealing component 200 is in the first state, the exhaust component 300 is used to reduce the air pressure in the enclosed space. When the product is tested for sealing, the product has been transported to the test area by the conveying component 100. At this time, the enclosed component 200 also works in the first state, that is, the product is in the enclosed space. The exhaust component 300 exhausts the enclosed space to reduce the air pressure in the enclosed space. Reducing the air pressure in the enclosed space is relative to the external environment, and the air pressure is reduced on the basis of atmospheric pressure. When the product is packaged and sealed, it is also carried out under normal atmospheric pressure, and protective gas is also filled into the product packaging, and the pressure in the product packaging is balanced with the atmospheric pressure. When the product is in a low-pressure environment (the air pressure is lower than the atmospheric pressure, that is, the low-pressure environment), the product with good sealing performance will not release pressure, so the product packaging will expand, that is, the volume will increase; while the product with poor sealing performance will leak gas, and after the gas leak, the pressure inside and outside the product is balanced, so the packaging volume of the product will remain unchanged. Therefore, products with good sealing performance and products with poor sealing performance can be judged by changes in appearance.

[0042] The visual inspection component 400 is arranged in a confined space, and the visual field of the visual inspection component 400 faces the inspection area. The function of the visual inspection component 400 is to obtain the appearance image of the product after depressurization, and the sealing performance of the product can be judged through program comparison and analysis.

[0043] In some embodiments, the visual inspection component 400 captures a side image of the product. After the product packaging expands, the most obvious change is that the thickness of the product increases when viewed from the side. Therefore, by judging whether the thickness of the product changes, the sealing performance of the product can be known. In one judgment method, the visual inspection component 400 captures an image of the product before depressurizing the enclosed space, and then captures an image of the product again after depressurizing, and compares the change in thickness of the product. If the thickness of the product increases, the sealing performance of the product is good, otherwise the sealing performance is poor and there is leakage.

[0044] Similarly, in some other embodiments, the visual inspection component 400 can take a side image of the product under normal atmospheric pressure and store it in the system, then put a product with known good sealing performance into a closed space, reduce the pressure to make it expand, and the visual inspection component 400 takes a side image of the expanded product and stores it in the system. In the subsequent inspection process, the visual inspection component 400 takes a side image of the product in the reduced pressure environment and compares it with the image stored in the system. If the thickness of the product is similar to the thickness of the expanded product, it is judged that the product has good sealing performance; if the thickness of the product is similar to the thickness of the product under normal pressure, it is judged that the product has poor sealing performance.

[0045] It should be understood that in order to prevent the appearance of the product from being damaged and to prevent the product from over-expanding and causing the package to explode, the air extraction component 300 needs to control the air pressure in the enclosed space. That is, the magnitude of the air pressure drop in the enclosed space needs to be controlled within an appropriate range so that the product package can be slightly expanded to be clearly observed.

[0046] The detection area is set on the conveying component 100, and the product can be tested for sealing on the product production line, with high detection efficiency, which is convenient for full detection of the product and avoids missed detection. In addition, when the closed space is restored to atmospheric pressure, the product will shrink naturally, which will not damage the appearance of the product, and is also suitable for full detection of the product.

[0047] Reference Figure 2 As shown, it can be understood that the conveying assembly 100 includes a first conveyor belt 110, a second conveyor belt 120 and a third conveyor belt 130, and the first conveyor belt 110, the second conveyor belt 120 and the third conveyor belt 130 are connected in sequence to form a conveying line, a gap is left between the first conveyor belt 110 and the second conveyor belt 120, and a gap is also left between the second conveyor belt 120 and the third conveyor belt 130, and the detection area is set on the second conveyor belt 120.

[0048] By setting up multiple sections of conveyor belts, a gap is left in the detection area, so that the detection area can be completely sealed. In this embodiment, the detection area is set on the second conveyor belt 120, and a gap is left between the second conveyor belt 120 and the first conveyor belt 110 and the third conveyor belt 130, respectively, so that the entire second conveyor belt 120 can be directly sealed.

[0049] It should be understood that, although there is a gap between the first conveyor belt 110 and the second conveyor belt 120, as long as the gap is adjusted to be much smaller than the length of the product, the product can still be transferred between the first conveyor belt 110 and the second conveyor belt 120. For example, when the product moves to the end of the first conveyor belt 110, the product extends out and hangs in the air, and is continuously conveyed by the first conveyor belt 110 until the end of the product is taken over by the second conveyor belt 120. The same is true for the transportation between the second conveyor belt 120 and the third conveyor belt 130.

[0050] It can be understood that the closed component 200 includes a first box body portion 210 and a second box body portion 220. The first box body portion 210 is fixed on one side of the second conveyor belt 120. The second box body portion 220 is connected to a driving mechanism 230. The driving mechanism 230 is used to drive the second box body portion 220 to move toward the first box body portion 210. The two side walls of the second box body portion 220 respectively pass through the gap between the first conveyor belt 110 and the second conveyor belt 120 and the gap between the second conveyor belt 120 and the third conveyor belt 130, so that the first box body portion 210 and the second box body portion 220 can be assembled into a complete box, and the second conveyor belt 120 is in the box.

[0051] The driving mechanism 230 may be a cylinder, which is used to push the second box body 220 to move. The driving mechanism 230 may also be driven by other structures, such as a screw-sleeve structure, in which case a motor is used to drive the screw to rotate, the sleeve moves along the screw, and the second box body 220 is fixed on the sleeve and moves with the sleeve. The second box body 220 moves toward the first box body 210 to assemble the first box body 210 and the second box body 220. As long as the opening of the first box body 210 and the opening of the second box body 220 correspond to each other, a closed space can be formed.

[0052] Reference Figure 2 and Figure 3 As shown, it can be understood that the first box body 210 is fixed below the second conveyor belt 120, and the opening of the first box body 210 is set upward, and the second box body 220 is mounted above the second conveyor belt 120, and the opening of the second box body 220 is set downward.

[0053] The first box body 210 is fixed below the second conveyor belt 120, and the second conveyor belt 120 can be set up on the inner side of the first box body 210, and a bracket can be set on the outer side of the first box body 210 to be placed on the ground. In this way, the first box body 210 and the second conveyor belt 120 are completely relatively static, which is conducive to maintaining the sealing performance between the first box body 210 and the second conveyor belt 120. In this structural scheme, the height of the first box body 210 facing one end of the second box body 220, that is, the upper end of the first box body 210, is lower than the conveying plane of the second conveyor belt 120. After this arrangement, the product can be continuously transported and transferred on the first conveyor belt 110, the second conveyor belt 120 and the third conveyor belt 130. When the second conveyor belt 120 (detection area) is to be constructed as a closed space, the driving mechanism 230 drives the second box body 220 to move downward, so that the side wall of the second box body 220 passes through the interval between the conveyor belts and then splices with the first box body 210.

[0054] Reference Figure 4 As shown, it can be understood that, in the joint plane of the first box body portion 210 and the second box body portion 220, the cross-section of the second box body portion 220 is smaller than the cross-section of the first box body portion 210, and in the joint plane, the inner wall of the first box body portion 210 is provided with a circle of support platform 211, and the surface of the support platform 211 is provided with a first sealing member 240, and the end of the opening of the second box body portion 220 can contact the first sealing member 240.

[0055] The second box body 220 can be inserted into the inner side of the first box body 210, and the end of the second box body 220 contacts the first sealing member 240 to achieve sealing of the joint plane. The first sealing member 240 can be a rubber ring with good sealing performance. When the end surface of the second box body 220 and the support 211 squeeze the rubber ring, the rubber ring can be deformed to completely fill the gap between the first box body 210 and the second box body 220, and the sealing performance is good.

[0056] It is understandable that, in the assembled plane, the outer side wall of the second box body portion 220 is provided with a circle of the second sealing member 250 , and the second sealing member 250 can be in contact with the inner side wall of the first box body portion 210 .

[0057] The second sealing member 250 can perform secondary sealing, further improving the sealing between the first box body 210 and the second box body 220. Good sealing is conducive to the operation of the air extraction component 300 and reduces the energy consumption of the air extraction component 300. It should be understood that the second sealing member 250 can also be a rubber ring, or a rubber strip.

[0058] Reference Figure 5As shown, it can be understood that the visual inspection component 400 includes a first camera 410, which is located in a confined space. The first camera 410 is mounted on the side of the second conveyor belt 120, and the lens direction of the first camera 410 is parallel to the conveying plane of the second conveyor belt 120.

[0059] The first camera 410 is placed on the side of the second conveyor belt 120 and can take a side image of the product to determine whether the sealing performance of the product is good.

[0060] The first camera 410 can take a side image of the product under normal atmospheric pressure and store it in the system, then put a product with known good sealing performance into a closed space, reduce the pressure to make it expand, and then the first camera 410 takes a side image of the expanded product and stores it in the system. In the subsequent inspection process, the first camera 410 takes a side image of the product in the reduced pressure environment and compares it with the image stored in the system. If the thickness of the product is similar to the thickness of the expanded product, it is judged that the product has good sealing performance; if the thickness of the product is similar to the thickness of the product under normal pressure, it is judged that the product has poor sealing performance.

[0061] If the conveying direction of the second conveyor belt 120 is defined as the X direction, and the direction perpendicular to the X direction in the conveying plane is the Y direction, then the first camera 410 can locate the products arranged along the X direction, specifically which position of the product has poor sealing performance.

[0062] It is understandable that if the products conveyed on the conveying assembly 100 are conveyed in a combined manner in rows and columns, a second camera 420 may also be provided. Figure 5 As shown, the visual inspection component 400 further includes a second camera 420 , which is mounted above the second conveyor belt 120 , and the lens direction of the second camera 420 is parallel to the conveying direction of the second conveyor belt 120 .

[0063] The products are transported in rows and columns. When the products move to the second conveyor belt 120, it can be understood that multiple products are arranged in both the X direction and the Y direction. The second camera 420 has the same main function as the first camera 410. The second camera 420 is used to determine the sealing performance of the products arranged in the Y direction. The second camera 420 can locate the products arranged in the Y direction, specifically which position has poor sealing performance.

[0064] Reference Figure 3 As shown, it can be understood that the vacuum component 300 includes a pump body 310, a connecting pipe 320 and a pressure release mechanism 330. The pump body 310 is connected to the connecting pipe 320, and the connecting pipe 320 is connected to the closed component 200. The pressure release mechanism 330 is arranged in the closed component 200 or the connecting pipe 320. The pressure release mechanism 330 is used to maintain the connection or disconnection between the closed space and the external environment.

[0065] The pump body 310 is used for pumping air, and is connected to the closed component 200 through the connecting pipe 320, and is used to extract the air in the closed space to reduce the air pressure in the closed space. It should be understood that only when the closed component 200 works in the first state position, a closed space is formed and the pump body 310 starts to work. When the air pressure in the closed space is reduced to the set value, the air pressure can also be maintained. Finally, the pump body 310 stops working, and when the air pressure in the closed space needs to be restored to normal atmospheric pressure, the closed space is connected to the external environment through the pressure release mechanism 330 to achieve rapid pressure recovery.

[0066] After the pressure in the enclosed space returns to normal atmospheric pressure, the enclosed component 200 can be easily switched to the second state position, so that the enclosed component 200 avoids the conveying component 100 and the product can continue to be transported.

[0067] It is understandable that the connecting pipe 320 is connected to a three-way valve, which serves as a pressure release mechanism 330. The first interface of the three-way valve is connected to the closed component 200, the second interface of the three-way valve is connected to the pump body 310, and the third interface of the three-way valve is connected to the external environment. The connection state can be controlled by switching the three-way valve. For example, the three-way valve first keeps the closed component 200 connected to the pump body 310, and the pump body 310 can reduce the pressure of the closed space. After the detection operation is completed, the three-way valve keeps the closed component 200 connected to the external environment to restore the pressure of the closed space.

[0068] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
