Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag production, in particular to a waste rejection device for packaging bag making equipment. The waste rejection device can be used for packaging bag making equipment. Background Art

[0002] With the development of social economy, packaging bags have become an indispensable and common tool in modern society. From the packaging of small items for daily shopping to the transportation of bulk goods in express logistics, the application scenarios of packaging bags are extremely wide, and people's requirements for packaging bags are getting higher and higher.

[0003] In order to improve the production efficiency and quality of packaging bags, automation has become an important development direction of packaging bag production machinery. However, assembly line production equipment may produce waste products that do not meet the use requirements due to uncontrollable factors (such as machine jams or failures). In order to prevent waste products from being put into use, there is often a waste removal process after the packaging bags are made.

[0004] In existing technology, reject removal primarily relies on manual inspection and screening. However, the long hours of inspection are labor-intensive and can lead to visual fatigue, which can lead to misjudgments and missed detections. Furthermore, different people's understanding of product standards can vary, leading to varying standards for reject assessment and inability to accurately reject products. Utility Model Content

[0005] The purpose of the utility model is to solve the technical problem in the prior art that manual detection and screening methods are used to stably and accurately remove waste packaging bags that do not meet the use requirements.

[0006] To solve the above technical problems, an embodiment of the present invention discloses a waste rejection device for a packaging bag making device, which includes a frame, a plurality of sealing stations sequentially arranged on the frame, and a transport component connecting the plurality of sealing stations.

[0007] The waste rejection device includes a plurality of industrial cameras arranged on a frame, and a waste collection component located downstream of a plurality of sealing stations along the transport direction of the transport component; each sealing station is correspondingly provided with at least one industrial camera, and the lens of each industrial camera is facing the sealing part of the packaging bag located at the corresponding sealing station.

[0008] Furthermore, the waste collection component includes a waste discharge accommodating chamber connected to the transport channel of the transport component, and a path switching member movably arranged between the transport channel and the waste discharge accommodating chamber, the path switching member can switchably connect the transport channel and the waste discharge accommodating chamber.

[0009] With the above technical solution, at least one industrial camera is provided at each sealing station of this rejection device. The industrial camera can take pictures of the part of the packaging bag being sealed at the sealing station, and then upload the taken image. The control unit compares the actual image with the preset standard image, makes a judgment, and obtains the detection result. If the sealing of the packaging bag at any sealing station is unqualified, when the packaging bag passes through the waste collection component on the transportation channel, the path switching component will connect the waste discharge cavity with the transportation channel, so as to remove the packaging bag from the transportation channel.

[0010] Compared with the manual detection and screening methods, this rejection device reduces the labor intensity of workers and saves labor costs. Moreover, by comparing the images taken by the industrial camera with the preset standard images to screen out defective products, the judgment criteria for each packaging bag are the same, and it can judge whether the packaging bag is qualified more stably and accurately. Specifically, at least one industrial camera is provided at each sealing station, which can accurately judge whether the packaging bag is sealed as expected at the sealing part, more accurately screen out the packaging bags that do not meet the use standards and remove them, improve the yield rate of the sold packaging bags, and increase the customer's favorability and trust.

[0011] The embodiment of the present invention also discloses a rejection device for a packaging bag manufacturing equipment. The frame has a side sealing station and a bottom sealing station arranged in sequence along the transportation direction. The side sealing station is provided with a side sealing component for side-sealing the packaging bag, and the bottom sealing station is provided with a bottom sealing component for bottom-sealing the packaging bag.

[0012] Among them, the multiple industrial cameras include a first industrial camera arranged at the output end of the side sealing component and a second industrial camera arranged at the output end of the bottom sealing component.

[0013] The first industrial camera takes pictures of the side sealing area of the packaging bag side-sealed by the side sealing component, and the second industrial camera takes pictures of the bottom sealing area of the packaging bag bottom-sealed by the bottom sealing component.

[0014] With the above technical solution, the first industrial camera can take pictures of the side sealing area of the packaging bag at the side sealing station, and then upload the taken images. The control unit compares the actual images with the preset standard images of the side sealing area. The second industrial camera can take pictures of the bottom sealing area of the packaging bag at the bottom sealing station, and then upload the taken images. The control unit compares the actual images with the preset standard images of the bottom sealing area. If the images taken by the first industrial camera and the second industrial camera of the same packaging bag meet the standards after being compared with the corresponding preset standard images in sequence, the packaging bag is discharged from the output end of the transportation component. If at least one of the images taken by the first industrial camera and the second industrial camera does not meet the standard after being compared with the preset standard image, the corresponding packaging bag is discharged into the waste receiving cavity through the path switching member.

[0015] This waste rejection device can take pictures of both the side sealing area and the bottom sealing area of the packaging bag, detect possible defects in any one of the sealing stations, ensure that the waste rejection device can accurately detect unqualified packaging bags, and make each batch of packaging bags output by the packaging bag manufacturing equipment have a high qualified rate.

A handle fixing component is further arranged on the frame, and the handle fixing component is located on the upstream side of the side sealing station in the transportation direction.

[0017] Moreover, the photographing area of the first industrial camera further includes the handle fixing area of the packaging bag.

[0018] With the above technical solution, the image taken by the first industrial camera includes not only the side sealing area of the packaging bag but also the handle fixing area. That is to say, when the first industrial camera uploads the taken image and the control unit compares the actual image with the preset standard image, it can not only compare the side sealing area of the packaging bag with the preset standard image but also compare the handle fixing area of the packaging bag with the preset standard image, ensuring that the handle can be installed on the bag body more accurately and reliably.

[0019] In summary, this waste rejection device can not only detect each sealing part of the packaging bag with a handle but also detect the handle fixing part of the packaging bag, ensuring that the packaging bags with possible defects in any of the above parts are removed.

[0020] An embodiment of the present utility model also discloses a waste rejection device for a packaging bag manufacturing equipment. The multiple industrial cameras further include a third industrial camera located downstream of the second industrial camera in the transportation direction.

[0021] Among them, the third industrial camera takes pictures of the contour shape of the entire packaging bag.

[0022] With the above technical solution, the third industrial camera can take pictures of the formation of the entire packaging bag's contour, and then upload the captured images. The control unit compares the actual images with the preset standard images to detect the overall appearance of the packaging bag, confirms that the finally output packaging bag has no other defects, and rejects the packaging bags with defects such as the packaging bag not being folded according to the predetermined creases or the assembly positions of a pair of handles on the bag body being offset, so as to output the packaging bags that can meet the usage requirements and ensure that each batch of packaging bags produced by the packaging bag manufacturing equipment has a high qualified rate.

[0023] An embodiment of the present utility model also discloses a waste rejection device for a packaging bag manufacturing equipment. The packaging bag output by the bottom sealing component is in a folded state, with a pair of side surfaces of the packaging bag being mutually attached, the bottom being folded, and a pair of handles of the packaging bag being mutually stacked.

[0025] With the above technical solution, the packaging bag output from the bottom sealing component is in a folded state, and the photographing area of the third industrial camera at least includes the bottom surface of the packaging bag and a pair of handles. The control unit compares the image fed back by the third industrial camera with the preset standard image, and can not only detect whether the bottom surface of the packaging bag is folded and sealed as expected, but also detect whether a pair of handles are symmetrically assembled on both sides of the bag body, so as to more accurately reject the packaging bags that may have defects.

[0026] An embodiment of the present utility model also discloses a waste rejection device for a packaging bag manufacturing equipment. Each industrial camera is installed on the machine frame through a mounting frame. The mounting frame includes a support rod with one end connected to the machine frame and a mounting rod provided on the support rod.

[0027] Among them, the extending direction of the mounting rod is perpendicular to the transporting direction of the transporting component, and the industrial camera is slidably arranged on the mounting rod along the extending direction of the mounting rod.

[0028] With the above technical solution, the industrial camera is arranged on the machine frame through the mounting frame, and for packaging bags or base materials of different specifications, the position of the industrial camera can be adjusted along the extending direction of the mounting rod to ensure that the lens of the industrial camera can be aligned with the sealing part of the packaging bag at the sealing station.

[0029] An embodiment of the present utility model also discloses a waste rejection device for a packaging bag manufacturing equipment. A light source is also provided on the mounting frame of each industrial camera. The light source is located on the upstream side of the industrial camera in the transporting direction, and the light emitted by the light source irradiates on the photographing area of the corresponding industrial camera.

[0030] Among them, the light source is installed on the mounting rod through a spacing adjusting member, and the spacing adjusting member can adjust the spacing between the light source and the industrial camera in the transportation direction.

[0031] With the above technical solution, by setting the light source to emit light and irradiate on the photographing area of the corresponding industrial camera, the photographing area is filled with light, ensuring that the industrial camera can capture a clearer image, so that the control unit can more accurately compare the actual image with the preset standard image and improve the accuracy of defect detection.

[0032] An embodiment of the present utility model also discloses a waste removing device of a packaging bag manufacturing device. The spacing adjusting member includes an adjusting rod and a mounting seat for setting the light source.

[0033] Among them, one end of the adjusting rod is rotatably connected to the mounting rod around the extending direction of the mounting rod, and the other end is hinged to the mounting seat; and one end of the adjusting rod can swing around the extending direction of the mounting rod to adjust the spacing between the light source and the industrial camera in the transportation direction.

[0034] And when viewed along the direction perpendicular to the transportation direction, the light source and the corresponding industrial camera are arranged staggeredly with each other.

[0035] With the above technical solution, both the industrial camera and the light source are assembled on the frame through the mounting frame, and the light source can adjust the spacing between the light source and the industrial camera in the transportation direction through the spacing adjusting member. On the one hand, it ensures that the light emitted by the light source can irradiate on the photographing area of the corresponding industrial camera; on the other hand, it avoids the light source from blocking the lens of the industrial camera.

[0036] An embodiment of the present utility model also discloses a waste removing device of a packaging bag manufacturing device. A dust removal fan is further arranged on the mounting frame, and the dust removal fan blows air towards the photographing area of the corresponding industrial camera.

[0064] As pointed out in the background art, with the development of social economy, the demand for packaging bags is also increasing. Automation has become an important development direction for packaging bag production machinery. However, the production equipment in the production line may produce waste products that do not meet the usage requirements due to uncontrollable factors (such as machine jams or failures).

[0065] In the prior art, the methods of manual inspection and screening are usually adopted. Manual inspection and removal require the long-term work of human eyes and hands, with a large labor intensity and easy to cause fatigue, resulting in misjudgment and missed judgment. Moreover, different people may have deviations in the understanding and perception of product standards, leading to different criteria for judging waste products and unable to accurately remove waste products.

[0066] To this end, the present utility model provides a waste rejection device for a packaging bag manufacturing device. This waste rejection device includes a plurality of industrial cameras disposed on a frame, and a waste collection component located downstream of a plurality of sealing stations along the transportation direction of a transportation component. At least one industrial camera is correspondingly disposed at each sealing station, and the lens of each industrial camera faces the sealing portion of the packaging bag at the corresponding sealing station, capable of accurately capturing an image of the packaging bag at the sealing portion. The industrial camera sends the captured image to a control unit for judgment. Moreover, the waste collection component includes a waste discharge receiving cavity communicated with the transportation channel of the transportation component, and a path switching member movably disposed between the transportation channel and the waste discharge receiving cavity. Under the guidance of the path switching member, waste products that do not meet the standards are output to the waste discharge receiving cavity, improving the yield of the packaging bags produced by the packaging bag manufacturing device.

[0067] To make the objectives, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0068] First, the structure of the packaging bag manufacturing device will be described.

[0069] As Figure 1 shown, this packaging bag manufacturing device 10 includes a frame 100, a plurality of sealing stations sequentially disposed on the frame 100, and a transportation component 110 connecting the plurality of sealing stations.

[0070] It should be noted that regarding the plurality of sealing stations on the frame 100, they can be specifically designed according to the packaging bags. Packaging bags can generally be divided into bottom-sealing types and side-sealing types according to the sealing method. Taking the bottom-sealing type as an example, during the production of this type of packaging bag, the base material is first folded in half along the width direction and sealed, thereby enclosing and forming a cylindrical structure. Then, one end of the base material of the cylindrical structure is sealed to form the bottom surface 304 of the packaging bag (see Figure 6 ), thereby forming the bag body of the packaging bag. That is to say, the bottom surface 304 of the bottom-sealing type packaging bag is formed by sealing, so at least a station for sealing the bottom surface 304 is provided on the frame 100. For the side-sealing type packaging bag, the bottom surface 304 connects a pair of front surfaces. The pair of front surfaces are bent towards each other relative to the bottom surface 304, and the two sides of the pair of front surfaces are sealed and connected to each other, thereby forming the bag body. This side-sealing type packaging bag is sealed through the side of the bag body, and a station for sealing the side is provided on the frame 100. Of course, the packaging bags are not limited to the bottom-sealing type and side-sealing type in the above embodiments. The plurality of sealing stations of the packaging bag manufacturing device 10 can be set according to the specific sealing method of the packaging bag. The number of sealing stations can be two, three, or four, and those skilled in the art can design according to the actual situation and specific requirements. This embodiment does not make specific limitations in this regard.

[0071] Furthermore, the packaging bag manufacturing device 10 should also be provided with a material storage component (such as a material storage roller, a material storage rack, etc.) for storing the base material. Under the transportation action of the transportation component 110, the base material stored in the material storage component passes through multiple stations on the frame 100, not limited to the above-mentioned sealing station, but may also be a cutting station, a hemming station, or a handle fixing station, etc. Regarding the specific structure of the packaging bag manufacturing device 10, this embodiment does not make specific limitations either.

[0072] The waste removal device provided in this embodiment will be described below.

[0073] As Figure 1 shown, the waste removal device 20 provided in this embodiment includes a plurality of industrial cameras 210 provided on the frame 100, and a waste collection component 220 located downstream of the plurality of sealing stations along the transportation direction of the transportation component 110; wherein, at least one industrial camera 210 is correspondingly provided for each sealing station, and the lens of each industrial camera 210 faces the sealing part of the packaging bag at the corresponding sealing station. It should be noted that the waste removal device 20 can be provided with two, three, four or other numbers of industrial cameras 210 on the frame 100. Each sealing station can be provided with one industrial camera 210, or two or three industrial cameras 210 can be provided. This embodiment does not make a unique limitation on this.

[0074] Moreover, the waste collection component 220 includes a waste discharge receiving cavity 221 communicated with the transportation channel of the transportation component 110, and a path switching member movably provided between the transportation channel and the waste discharge receiving cavity 221. The path switching member can switchably communicate the transportation channel with the waste discharge receiving cavity 221.

[0075] Such a waste removal device 20 has a plurality of industrial cameras 210 on the frame 100, and at least one industrial camera 210 is provided at each sealing station. The industrial camera 210 can take pictures of the sealing part of the packaging bag at the sealing station, and then upload the taken image. The control unit compares the actual image with the preset standard image and makes a judgment to obtain the detection result. If the sealing of the packaging bag at any one of the sealing stations is unqualified, when the packaging bag passes through the waste collection component 220 on the transportation channel, the path switching member will communicate the waste discharge receiving cavity 221 with the transportation channel, so as to remove the packaging bag from the transportation channel. It should be noted that the control unit can be a commonly used control chip in the art.

[0076] This rejection device 20 reduces the labor intensity of workers and saves labor costs compared with manual inspection and screening methods. Moreover, by comparing the images captured by the industrial camera 210 with the preset standard images to screen out defective products, the judgment criteria for each packaging bag are the same, and it can more stably and accurately judge whether the packaging bag is qualified. Specifically, at least one industrial camera 210 is provided at each sealing station, which can accurately judge whether the packaging bag is sealed as expected at the sealing part, more accurately screen out the packaging bags that do not meet the usage standards and reject them, improve the yield rate of the sold packaging bags, and increase the customer's favorability and trust.

[0077] It should be noted that the industrial camera 210 included in this rejection device 20, also commonly known as an industrial video camera, has high image stability, high transmission ability, high anti-interference ability, etc. The performance of the industrial camera 210 is stable and reliable, easy to install, the camera structure is compact and strong, not easy to be damaged, and it can work continuously for a long time and can be used in a relatively poor environment. The industrial camera 210 can be divided into a line array camera and a area array camera. Among them, the area array camera can be further subdivided into a large area array camera, a medium and small area array camera, and a high-speed area array camera according to the size of the sensor and the camera frame rate. Those skilled in the art can design according to the actual situation and specific requirements, and this embodiment does not make specific limitations on this.

[0078] For the convenience of understanding, the following takes the packaging bag manufacturing equipment 10 for manufacturing bottom-sealed packaging bags as an example for illustration.

[0079] As Figure 1 shown, in an embodiment, on the frame 100, there are a side sealing station 101 and a bottom sealing station 102 arranged in sequence along the transportation direction. The side sealing station 101 is provided with a side sealing component for side-sealing the packaging bag, and the bottom sealing station 102 is provided with a bottom sealing component for bottom-sealing the packaging bag at the bottom surface 304 (see Figure 6 ).

[0080] Specifically, as Figure 3 shown, the side sealing component can spray adhesive on one side in the width direction of the base material 30 to form a side sealing area 301, and fold the base material 30 along its length direction. The two side edges of the base material 30 in the width direction are connected by the side sealing area 301 and surrounded into a cylinder. Further, the downstream bottom sealing component can perform the next sealing on the cylindrical base material 30. As Figure 5 shown, the bottom sealing component can spray adhesive at one end in the length direction of the base material 30 (that is, the lower end in Figure 5 ) to form a bottom sealing area 302, and connect one end of the base material 30 through the bottom sealing area 302 to form the bottom surface 304 of the packaging bag (see Figure 6). It should be noted that before the cylindrical substrate 30 enters the bottom sealing component, a bottom-opening process needs to be performed first, that is, one end of the cylindrical substrate 30 is folded as shown in Figure 5 the state shown.

[0081] Regarding the specific structures of the side sealing component and the bottom sealing component, this embodiment does not specifically limit them, as long as the above-mentioned sealing functions can be achieved. Among them, the adhesive can be a commonly used glue solution in the art, etc.

[0082] In this embodiment, as shown in Figure 1 and Figure 2 , a plurality of industrial cameras 210 include a first industrial camera 211 disposed at the output end of the side sealing component and a second industrial camera 212 disposed at the output end of the bottom sealing component.

[0083] The first industrial camera 211 takes pictures of the side sealing area 301 of the packaging bag that has been side-sealed through the side sealing component (see Figure 3 ), and the second industrial camera 212 takes pictures of the bottom sealing area 302 of the packaging bag that has been bottom-sealed through the bottom sealing component (see Figure 5 ).

[0084] In this embodiment, the first industrial camera 211 can take pictures of the side sealing area 301 of the packaging bag at the side sealing station 101, and then upload the taken image. The control unit compares the actual image with the preset standard image of the side sealing area 301; the second industrial camera 212 can take pictures of the bottom sealing area 302 of the packaging bag at the bottom sealing station 102, and then upload the taken image. The control unit compares the actual image with the preset standard image of the bottom sealing area 302. If the images taken by the first industrial camera 211 and the second industrial camera 212 of the same packaging bag are both in line with the standards after being compared with the corresponding preset standard images, the packaging bag is discharged from the output end of the transportation component 110; if at least one of the images taken by the first industrial camera 211 and the second industrial camera 212 does not meet the standard after being compared with the preset standard image, the corresponding packaging bag is discharged into the waste discharge cavity 221 through the path switching member.

[0085] This waste rejection device 20 can take pictures of both the side sealing area 301 and the bottom sealing area 302 on the packaging bag, detect possible defects in any one of the sealing stations, ensure that the waste rejection device 20 can accurately detect unqualified packaging bags, and enable each batch of packaging bags output by the packaging bag manufacturing equipment 10 to have a high qualified product rate.

[0086] It should be noted that the control unit compares the actual image captured by the first industrial camera 211 with the image of the preset standard side sealing area 301, mainly comparing and analyzing whether the adhesive is distributed in the side sealing area 301 in sufficient quantity as expected. Similarly, the control unit compares the actual image captured by the second industrial camera 212 with the preset bottom sealing area 302, mainly comparing and analyzing whether the adhesive is distributed in the bottom sealing area 302 in sufficient quantity as expected, so as to ensure that the packaging bag can be firmly connected in the corresponding sealing area. If the coating position of the adhesive is offset or the coating amount of the adhesive is less than expected, it may lead to a decrease in the connection strength of the packaging bag at the sealing part.

[0087] Furthermore, the packaging bags in the prior art often have handles for easy carrying assembled in the bag mouth area. Therefore, a handle fixing component (not shown in the figure) is also provided on the frame 100 of the packaging bag manufacturing device 10, and the handle fixing component is located on the upstream side of the side sealing station 101 in the transportation direction.

[0088] Specifically, as Figure 3 shown, the handle fixing component needs to spray adhesive on the handle fixing area 303 on the substrate or the free end of the handle (i.e., the part connecting the bag body), and then press the free end of the handle 40 on the handle fixing area 303 on the substrate, so that the free end of the handle 40 and the substrate in the handle fixing area 303 are firmly connected through the adhesive. Of course, regarding the specific structure of the handle fixing component, those skilled in the art can design it according to the actual situation and specific requirements, and this embodiment does not make specific limitations on this.

[0089] And, as Figure 3 shown, the photographing area of the first industrial camera 211 in this embodiment also includes the handle fixing area 303 of the packaging bag.

[0090] In this embodiment, the image captured by the first industrial camera 211 includes not only the side sealing area 301 of the packaging bag, but also the handle fixing area 303. That is to say, when the first industrial camera 211 uploads the captured image and the control unit compares the actual image with the preset standard image, it can not only compare the side sealing area 301 of the packaging bag with the preset standard image, but also compare the handle fixing area 303 of the packaging bag with the preset standard image, ensuring that the handle 40 can be installed on the bag body more accurately and reliably. As mentioned above, when the control unit compares the actual image captured by the first industrial camera 211 with the preset image, it is also comparing and analyzing whether the adhesive is distributed in the handle fixing area 303 in sufficient quantity as expected.

[0091] In summary, this rejection device 20 can not only detect each sealing part of the packaging bag with a handle 40, but also detect the handle fixing part of the packaging bag to ensure that the packaging bags with possible defects in any of the above parts are rejected.

[0092] Furthermore, as shown in Figure 1 and Figure 4 , in an embodiment, the multiple industrial cameras 210 further include a third industrial camera 213 located downstream of the second industrial camera 212 in the transportation direction.

[0093] Among them, the third industrial camera 213 takes pictures of the contour shape of the entire packaging bag.

[0094] In this embodiment, the third industrial camera 213 can take pictures of the contour formation of the entire packaging bag, and then upload the taken image. The control unit compares the actual image with the preset standard image to detect the overall appearance of the packaging bag. It is confirmed that the finally output packaging bag has no other defects, and the packaging bags with defects such as the packaging bag not being folded according to the predetermined crease or the assembly position of a pair of handles on the bag body being offset are rejected, so as to output the packaging bags that can meet the usage requirements and ensure that each batch of packaging bags produced by the packaging bag manufacturing equipment 10 has a high qualified rate.

[0095] More specifically, as shown in Figure 6 , the packaging bag output by the bottom sealing component is in a folded state, a pair of sides of the packaging bag are attached to each other, the bottom surface 304 is folded, and a pair of handles 40 of the packaging bag are stacked on top of each other.

[0096] Among them, the photographing area of the third industrial camera 213 at least includes the bottom surface 304 of the packaging bag and a pair of handles 40, and the bottom surface 304 is folded towards one side and attached to the outside of the corresponding side.

[0097] In this embodiment, the packaging bag output from the bottom sealing component is in a folded state. The photographing area of the third industrial camera 213 at least includes the bottom surface 304 of the packaging bag and a pair of handles 40. The control unit compares the image fed back by the third industrial camera 213 with the preset standard image, and can not only detect whether the bottom surface 304 of the packaging bag is folded and sealed as expected, but also detect whether a pair of handles 40 are symmetrically assembled on both sides of the bag body, so as to more accurately reject the packaging bags that may have defects. Regarding the folding and sealing method of the bottom surface 304, it is not limited to the structures shown in Figure 5 and Figure 6 , and can also be any other folding method. This embodiment does not make specific limitations on this.

[0098] It should be noted that the image of the contour shape of the entire packaging bag taken by the third industrial camera 213 is not limited to such asFigure 6 For the form of such a packaging bag shown, for example, in another embodiment, a pair of side surfaces of the packaging bag are attached to each other, and the bottom surface 304 is folded inwardly between the pair of side surfaces. That is to say, there is no crease on the side surface of the packaging bag where the bottom surface 304 is bent. Or in another embodiment, the packaging bag is in an unfolded state, and a pair of side surfaces are spaced apart from each other. Moreover, the packaging bag is photographed in a lying state with one side surface grounded. This embodiment does not make a unique limitation on this.

[0099] Regarding the waste removal device 20 provided in this embodiment, the multiple industrial cameras 210 are not limited to the settings of the first industrial camera 211, the second industrial camera 212, and the third industrial camera 213 disclosed in the above embodiment, and can also be arranged in a manner of setting any one or any two. Of course, for the packaging bag manufacturing device 10 for other packaging bags (such as side-sealed types), those skilled in the art can set the industrial camera 210 according to the corresponding sealing station. This embodiment does not make a unique limitation on this.

[0100] The specific structure of the waste collection component 220 will be described below.

[0101] As Figure 7 shown, the waste collection component 220 includes a path switching member (not shown in the figure) and a waste discharge receiving cavity 221. The path switching member can be a commonly used baffle in the art. The baffle is flush with the side wall surface of the transportation channel in the natural state to play a role in connecting transportation. When the baffle needs to guide the packaging bag in the transportation channel into the waste discharge receiving cavity 221, the baffle can extend in a swinging or translational manner, thereby blocking the transportation channel and at the same time opening the waste discharge receiving cavity 221, so that the waste packaging bag in the transportation channel enters the waste discharge receiving cavity 221. The waste discharge receiving cavity 221 can be an open or sealed storage chamber. This embodiment does not make a specific limitation on this.

[0102] Furthermore, regarding the specific structure of the path switching member and the driving structure for driving the movement of the path switching member, those skilled in the art can design according to the actual situation and specific requirements. This embodiment does not make a specific limitation on this.

[0103] Taking a single industrial camera 210 as an example, the installation structure and related structures of the industrial camera 210 on the frame 100 will be described below.

[0104] As Figure 8 shown, each industrial camera 210 is installed on the frame 100 through a mounting bracket 230. The mounting bracket 230 includes a support rod 231 with one end connected to the frame 100 and a mounting rod 232 provided on the support rod 231.

[0105] Among them, the extending direction of the installation rod 232 is perpendicular to the transportation direction of the transportation component 110. The industrial camera 210 is slidably arranged on the installation rod 232 along the extending direction of the installation rod 232, so as to conveniently adjust the position aligned by the lens of the industrial camera 210 and ensure that the industrial camera 210 can accurately capture the corresponding part on the packaging bag.

[0106] Regarding the specific structure for installing the industrial camera 210, it is not limited to the structure of the above-mentioned mounting bracket 230. In another alternative embodiment, the industrial camera 210 is arranged on a guide rail extending along the transportation direction, and it is ensured that the lens of the industrial camera 210 can be aligned with the packaging bag in the transportation channel. By adjusting the position of the industrial camera 210 on the guide rail, the industrial camera 210 can capture images of the packaging bag at any station.

[0107] Furthermore, in order to ensure that the industrial camera 210 can capture clearer images, especially in some areas with relatively dim light inside the frame 100, in one embodiment, as Figure 8 shown, in one embodiment, a light source 240 is further arranged on the mounting bracket 230 of each industrial camera 210. The light source 240 is located on the upstream side of the industrial camera 210 in the transportation direction, and the light emitted by the light source 240 irradiates on the photographing area of the corresponding industrial camera 210. It should be noted that the light source 240 can be a commonly used LED lamp or the like in the art.

[0108] In this embodiment, the light source 240 emits light to irradiate on the photographing area of the corresponding industrial camera 210 to fill light for the photographing area, ensuring that the industrial camera 210 can capture clearer images, so as to facilitate the control unit to more accurately compare the actual image with the preset standard image and improve the accuracy of defect detection.

[0109] In one embodiment, the light source 240 is installed on the installation rod 232 through a spacing adjusting member 250, and the spacing adjusting member 250 can adjust the spacing between the light source 240 and the industrial camera 210 in the transportation direction.

[0110] Specifically, the spacing adjusting member 250 includes an adjusting rod 251 and a mounting seat 252 for installing the light source 240. One end of the adjusting rod 251 is rotatably connected to the installation rod 232 around the extending direction of the installation rod 232, and the other end is hinged to the mounting seat 252; and one end of the adjusting rod 251 can swing around the extending direction of the installation rod 232 to adjust the spacing between the light source 240 and the industrial camera 210 in the transportation direction.

[0111] And when viewed along the direction perpendicular to the transportation direction, the light source 240 and the corresponding industrial camera 210 are arranged staggeredly with each other.

[0112] In this embodiment, the light source 240 can adjust the distance between the light source 240 and the industrial camera 210 in the transportation direction through the distance adjustment member 250. On the one hand, it ensures that the light emitted by the light source 240 can irradiate the photographing area of the corresponding industrial camera 210. On the other hand, it avoids the light source 240 from blocking the lens of the industrial camera 210.

[0113] In another embodiment, the distance adjustment member 250 includes a slide rail extending in the transportation direction and a slider provided with the light source 240. The distance between the light source 240 and the corresponding industrial camera 210 is adjusted by adjusting the position of the slider. That is to say, the specific structure of the distance adjustment member 250 is not limited to the structure in the above embodiment, and those skilled in the art can design according to the actual situation and specific requirements. This embodiment does not make a unique limitation on this.

[0114] Further, during the production of the packaging bag by the packaging bag manufacturing device, the base material will be cut. During this process, the cut part of the base material may generate debris and adhere to the base material or the packaging bag. That is, when the industrial camera 210 takes an image, there are obstacles on the photographed packaging bag or base material, which affects the detection accuracy. For this reason, in one embodiment, a dust removal fan 260 is further provided on the mounting bracket 230 of the industrial camera 210, and the dust removal fan 260 blows air toward the photographing area of the corresponding industrial camera 210. Among them, the dust removal fan 260 can be a common blower in the art, etc.

[0115] Specifically, the dust removal fan 260 is connected to the mounting rod 232 through the auxiliary support rod 233. One side of the auxiliary support rod 233 is slidably connected to the mounting rod 232 along the axial direction, and the dust removal fan 260 is rotatably connected to the other side of the auxiliary support rod 233. Moreover, the air outlet of the dust removal fan 260 is aligned with the photographing area of the industrial camera 210.

[0116] In this embodiment, the dust removal fan 260 can blow air toward the photographing area of the corresponding industrial camera 210 to remove impurities that may be left on the packaging bag or the base material, ensure that there are no obstacles on the packaging bag or the base material, and enable the control unit to more accurately compare the actual image with the preset standard image, reducing the risk of misjudgment.

[0117] Further, in one embodiment, the industrial camera 210 is communicatively connected to the image acquisition card of the packaging bag manufacturing device 10, and the image acquisition card and the path switching member are communicatively connected to the control unit.

[0118] In this embodiment, the industrial camera 210 captures an image and transmits it to an image acquisition card. The image acquisition card then transmits the signal to a control unit, which compares the actual image with a preset standard image for judgment and controls the operation of a path switching member to output the conforming packaging bags from the output end of the transport channel, and outputs the non-conforming packaging bags to a waste discharge cavity 221.

[0119] Furthermore, as Figure 1 shown, an embodiment of the present invention also discloses a packaging bag manufacturing device 10, which includes a waste removal device 20 of any one of the above-mentioned packaging bag manufacturing devices 10. And, the transport assembly 110 includes multiple transport belts respectively connecting adjacent two workstations. It should be noted that the transport assembly 110 is not limited to the structure of transport belts, and can also be a suction cup that can move along the transport direction, etc.

[0120] When manufacturing packaging bags with this packaging bag manufacturing device 10, the waste removal device 20 can accurately judge whether the packaging bags are sealed as expected at the sealing part, more accurately screen out the non-conforming packaging bags, and guide the waste products into the waste discharge cavity 221 through the path switching member, and each batch of packaging bags produced by the packaging bag manufacturing device 10 has a high qualified product rate.

[0121] Of course, regarding the specific structure of the packaging bag manufacturing device 10, it is not limited to the packaging bags for bottom sealing in the above-mentioned embodiment, and can also be packaging bags for side sealing. This embodiment does not make a unique limitation on this.
