Description

Technical Field

[0001] The present invention relates to the technical field of tobacco production detection equipment, and in particular to a detection device, detection equipment and detection method for judging box bagging. Background Art

[0002] Expanded tobacco is tobacco that has been processed by expansion technology. Tobacco processed by expansion technology can increase the filling value of tobacco, reduce the raw material consumption of cigarettes, and also reduce the tar content of cigarettes.

[0003] The expanded tobacco transport room is mainly responsible for the automated bagging, boxing and packaging of the expanded tobacco used on the tobacco production line. However, since the bagging success rate of the bagging machine on the production line is not 100%, there will be cases where the tobacco boxes are not bagged. In actual production, the bagging situation is usually checked manually. Once the inspectors fail to find the unbagged cigarette boxes in time, the unbagged cigarette boxes will enter the next process for continued production, resulting in the unsealed packaging of the exported tobacco, which will not only cause the tobacco to be scattered, making the process quality of the tobacco unable to be guaranteed, but also cause the tobacco to become moldy and unusable, resulting in waste. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] The embodiments of the present invention provide a detection device, a detection equipment and a detection method for determining whether a box is bagged, so as to solve the quality defect of the cigarette box not being sealed tightly due to the failure of manual inspection to detect the bagged cigarette box in time in the prior art.

[0006] (II) Technical solution

[0007] In order to solve the above technical problems, the present invention provides a detection device for judging whether a box is bagged, comprising at least one pair of detection mechanisms respectively arranged on both sides of a conveying mechanism, wherein the conveying mechanism is used to drive the box to be tested to pass horizontally between each pair of the detection mechanisms; each pair of the detection mechanisms respectively emits scanning light beams relative to each other, so that each scanning light beam forms scanning points on both sides of the box to be tested, and the scanning points are used to detect the packaging bags located on the outer side of the box to be tested and feed back signals.

[0008] In some embodiments, each of the detection mechanisms includes a support column and a transmitting head. The two support columns stand opposite to each other on both sides of the conveying mechanism. The transmitting head is fixed on the top of each support column. Each transmitting head is used to emit a scanning light beam to the two sides of the box to be tested.

[0009] In some embodiments, the detection mechanism further includes an angle adjuster, which is installed on the top of the support column and connected to the transmitting head.

[0010] In some embodiments, the detection mechanism further includes a control box equipped with an alarm mechanism and a control circuit board. The control box is fixed on the support column, and the alarm mechanism is fixed on the control box and electrically connected to the control circuit board. When the signal fed back by the scanning points is a non-conforming signal, the control circuit board receives the non-conforming signal and activates the alarm mechanism.

[0011] In some embodiments, the alarm mechanism includes an alarm light and an alarm bell. The alarm light is fixed on the top of the box body of the control box, and the alarm bell is electrically connected to the control circuit board.

[0012] In some embodiments, the detection mechanism further includes an extension frame. One end of the extension frame is connected to the bottom of the transmitting head, and the other end is connected to the top of the control box. The extension frame extends outward relative to the box wall of the control box.

[0013] In some embodiments, the conveying mechanism includes at least two conveying units, and each pair of the detection mechanisms are respectively arranged on both sides of the connection of two adjacent conveying units.

[0014] The present invention also provides a cigarette box automatic detection device, including the detection device for judging the bagging of the box body as described above.

[0015] The present invention also provides a detection method for judging the bagging of the box body, which is proposed based on the detection device for judging the bagging of the box body as described above;

[0016] The detection method includes:

[0017] Establish a scanning area on the conveying mechanism by using any pair of relatively emitted scanning light beams, so that the box body can pass through the scanning area when it travels;

[0018] When the box body to be detected travels and passes through the scanning area, the two scanning light beams are respectively emitted to both sides of the box body to be detected, so that continuous scanning points are respectively formed on both sides of the box body to be detected. The continuous scanning points are used to continuously detect the packaging bag located on the outer side of the box body to be detected and feed back signals;

[0019] Establish a qualified parameter critical value that can determine the qualified state of the box body, and compare the parameter values of the feedback signals from both sides of the box body to be detected with the qualified parameter critical value respectively to obtain comparison result data;

[0020] When the parameter value of any one of the feedback signals is greater than or equal to the qualified parameter critical value, it is judged that the comparison result data is unqualified, and the alarm mechanism is activated.

[0021] In some embodiments, after determining that the comparison result data is unqualified when the parameter value of any one of the feedback signals is greater than or equal to the qualified parameter critical value and activating the alarm mechanism, the method further includes:

[0022] Distinguish the parameter comparison results corresponding to each side of the to-be-tested box body in the comparison result data;

[0023] According to the parameter comparison results, display the bagging status of each side of the to-be-tested box body in the upper-level system, where the bagging status of each side of the to-be-tested box body includes qualified and unqualified.

[0024] (III) Beneficial effects

[0025] The above technical solution of the present invention has the following beneficial effects: The detection device for judging the bagging of a box body according to the present invention includes at least a pair of detection mechanisms respectively oppositely arranged on both sides of a conveying mechanism. The conveying mechanism is used to drive the to-be-tested box body to horizontally pass between each pair of detection mechanisms; each pair of detection mechanisms respectively oppositely emit scanning beams, so that each scanning beam forms scanning points on both sides of the to-be-tested box body. The scanning points are used to detect the packaging bag located on the outer side of the to-be-tested box body and feedback signals. This device uses static scanning detection to achieve relative dynamic scanning detection, that is, during the movement of the to-be-tested box body, the scanning points falling on both sides of the box body are used to automatically detect the packaging bag outside the box body and feedback signals, so as to realize line scanning formed by point scanning, and further form plane scanning of the box body plane, so as to realize the overall packaging bag scanning detection work on the outer side of the cigarette box, effectively avoiding the quality problem of the cigarette box with loose sealing caused by the failure to detect the unbagged cigarette box in time by manual inspection in the prior art, and avoiding the decline of product quality and the waste of production resources caused by the unbagged box body entering the next process.

[0026] This detection device adopts non-contact detection, can be connected to the original production equipment without damage, and automatically detects during the movement of the to-be-tested box body. When no unqualified products are found, it will not block the movement of the box body, so as not to interfere with the normal progress of the original production process, making the cigarette box production line have good production and transportation continuity, and can greatly reduce the labor cost.

[0027] This detection device directly detects the appearance of the box body, with accurate detection results, high detection efficiency, and the detection data is not easily affected by the adverse position of the box body. For example, when the box body is tilted or the queue distance changes, it is not easy to have an adverse impact on the detection results. Brief description of the drawings

[0033] The following will further describe in detail the implementation manners of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0034] In the description of the present invention, unless otherwise specified, "a plurality of" means two or more. The orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or positional relationship shown in the drawings, and is 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 to the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0035] Such as Figure 1As shown in the figure, this embodiment provides a detection device for judging the bagging of a box body. The device includes at least a pair of detection mechanisms respectively arranged on both sides of the conveying mechanism 6 opposite to each other, wherein the conveying mechanism 6 is used to drive the box body 3 to be tested to pass horizontally between each pair of detection mechanisms. The conveying mechanism 6 is installed in the outbound room or other appropriate positions and can be directly connected to the cigarette box production equipment. Each pair of detection mechanisms respectively emits a scanning beam, and the scanning beam is directed at the side of the box body 3 to be tested, so that each scanning beam forms a scanning point 5 on both sides of the box body 3 to be tested, and the scanning point 5 is used to detect the packaging bag 4 on the outer side of the box body 3 to be tested and feedback a signal.

[0036] When the device of this embodiment is working, the position where the scanning beam contacts the outer side of the box body 3 to be tested is regarded as the scanning point 5. If the scanning beam between the detection mechanism and the scanning point 5 passes through the packaging bag 4, it is regarded that the bagging at the position of the scanning point 5 is qualified; if the scanning beam between the detection mechanism and the scanning point 5 does not pass through the packaging bag 4, it is regarded that the bagging at the position of the scanning point 5 is unqualified. During the detection process, since the box body 3 to be tested is driven by the conveying mechanism 6 to travel in a direction perpendicular to the scanning beam, the box body 3 to be tested passes through the scanning line network formed by two scanning beams during the traveling process, so that during the traveling process of the box body 3 to be tested, the side of the box body 3 to be tested is scanned by a plurality of dense points by using the scanning beam, so as to form a line scan along the traveling direction of the box body 3 to be tested, and the double-side line scan of the box body 3 to be tested is realized by using the paired detection mechanisms, so as to realize the surface scan of the cross-section at any height of the box body 3 to be tested.

[0037] In this embodiment, Figure 1 The arrow shown is the traveling direction of the scanning point 5 of the scanning beam, that is, the traveling direction of the box body 3 to be tested is opposite to the arrow. The line scanning direction formed by the scanning beam on the side of the box body 3 to be tested is the same as the arrow direction. Taking the end of the arrow as the front of the box body 3 to be tested and the direction pointed by the arrow as the rear of the box body 3 to be tested. The device realizes the relative dynamic scanning detection by using static scanning detection, that is, during the traveling process of the box body 3 to be tested, the packaging bag 4 on the outer side of the box body 3 to be tested is automatically detected and the signal is fed back by using the scanning points 5 falling on both sides of the box body 3 to be tested, so as to realize the formation of line scanning from point scanning, and further form the plane scanning of the box body 3 to be tested, so as to realize the scanning detection work of the whole packaging bag 4 on the outer side of the cigarette box, effectively avoiding the quality problem of the cigarette box with loose sealing caused by the failure to timely check the unbagged cigarette box by manual in the prior art, and avoiding the decline of product quality and the waste of production resources caused by the unbagged box body 3 to be tested entering the next process.

[0038] In this embodiment, as Figure 1As shown in the figure, the conveying mechanism 6 includes at least two conveying units, and each pair of detection mechanisms is respectively arranged on both sides of the connection of two adjacent conveying units. Each conveying unit includes a track frame and a plurality of conveying rollers. The track frames are connected in sequence. Each pair of detection mechanisms is respectively arranged on both sides of the connection of two adjacent track frames. A plurality of rotatable conveying rollers are arranged in sequence in each track frame. After the box 3 to be tested enters the conveying mechanism 6, it advances under the push of the conveying rollers, and when passing through the connection of two conveying units, it is detected in real time by the detection mechanisms on both sides during the advancement.

[0039] In a preferred embodiment, when the scanning point 5 is located at the forefront of the box 3 to be tested, the position of the packaging bag 4 outside the front side of the box 3 to be tested can be scanned. Similarly, when the scanning point 5 is located at the rearmost of the box 3 to be tested, the position of the packaging bag 4 outside the rear side of the box 3 to be tested can also be scanned. Thus, the device can utilize the point-line-plane scanning mechanism and the double-side scanning principle to realize the qualified judgment of the position of the packaging bag 4 on the overall side of the box to be tested, and further improve the detection accuracy and detection efficiency of the bagging qualification rate of the box 3 to be tested. The detection mechanism adopts full-spectrum detection, with a large wavelength range and a wide range of detectable objects. And since the device detects the appearance of the cigarette box, the accuracy of its detection results is not easily affected by the inclination of the box 3 to be tested or the change in the spacing of the boxes 3 to be tested moving continuously.

[0040] In a preferred embodiment, each detection mechanism includes a support column 7 and a transmitting head. The transmitting head preferably includes a white LED spotlight and a corresponding light receiving element. The light receiving element receives the spectrum formed by the self-scanning beam on the side of the box 3 to be tested to obtain spectral feedback information, and detects according to the appearance color of the target object, so that fine color differences can be accurately captured.

[0041] Two support columns 7 stand opposite each other on both sides of the conveying mechanism 6. The top of each support column 7 is respectively fixed with a transmitting head, and each transmitting head is respectively used to emit a scanning beam to the two sides of the box 3 to be tested. The height of the two beams can be adjusted by the height of the support column 7, or can be adjusted by changing the height and pitch angle of the transmitting head; the incident angles of the two beams shooting at the side of the box 3 to be tested can be adjusted by changing the rotation angle of the transmitting head.

[0042] In a preferred embodiment, in order to ensure that the position of the scanning point 5 is not easily deviated when the scanning beam shoots at the side of the box 3 to be tested, it is preferred that the emission angles of the two beams are respectively perpendicular to the advancing direction of the box 3 to be tested.

[0043] In a preferred embodiment, the detection mechanism of this embodiment further includes an angle adjuster. The angle adjuster is installed on the top of the support column 7 and is connected to the transmitting head. As Figure 2As shown, the angle adjuster is fixed at the top of the support column 7, and the angle adjuster includes a fan-shaped panel and a movable needle. One end of the movable needle is swingably connected to the bottom center of the fan-shaped panel, and the transmitter is connected to the movable needle of the angle adjuster. The panel of the angle adjuster is provided with scale lines that can display the current light beam emission angle of the transmitter, and the movable needle is embedded in the panel, so that the angle value of the transmitter is shown on the scale lines of the panel.

[0044] In a preferred embodiment, the detection mechanism further includes a control box 8 equipped with an alarm mechanism and a control circuit board, and the control box 8 is fixed on the support column 7. The chip of the control circuit board is equipped with a programmable controller, so that the received feedback signal can be analyzed, and the state of the target object can be detected by using the different principles of material reflection chromatography to distinguish whether the cigarette box is bagged, and the tolerance value is used to eliminate the shaking interference, so that the detection result data is more accurate and reliable. It is understandable that in order to eliminate electromagnetic interference during detection, the control box 8 is provided with a reliable grounding terminal.

[0045] The alarm mechanism is fixed on the control box 8 and is electrically connected to the control circuit board. When the signal fed back by the scanning point 5 is a qualified signal, that is, the scanning light beam passes through the packaging bag 4, the control circuit board receives the qualified signal, and the alarm mechanism is not activated; when the signal fed back by the scanning point 5 is an unqualified signal, that is, the scanning light beam does not pass through the packaging bag 4, the control circuit board receives the unqualified signal and activates the alarm mechanism to promptly remind the operator that the box body 3 to be tested that currently passes through the scanning light beam is not bagged.

[0046] In a preferred embodiment, the alarm mechanism includes an alarm light 9 and an alarm bell, the alarm light 9 is fixed on the top of the test box 3 of the control box 8, and the alarm bell is electrically connected to the control circuit board. When the control circuit board receives an unqualified signal, the alarm light 9 and the alarm bell can be activated at the same time to remind the operator both visually and audibly.

[0047] In a preferred embodiment, in order to ensure that the transmitter heads of the two detection mechanisms can be aligned with each other, so as to accurately define the scanning area network on the conveying mechanism 6 using the scanning light beam, the detection mechanism preferably also includes a protruding frame 23, one end of the protruding frame 23 is connected to the bottom of the transmitter head, and the other end is connected to the top of the control box 8, and the protruding frame 23 extends outward relative to the box wall of the control box 8, so as to ensure that the transmitter head on the side with the protruding frame 23 can be aligned with the transmitter head of the opposite detection mechanism. It is understandable that the specific structure of the protruding frame 23 can be set according to the relative distance between the target installation position of the transmitter head and the position of the control box 8, and can be set to an L-shaped, 7-shaped or truss structure, as long as it can ensure that the two transmitter heads on both sides of the conveying mechanism 6 are relatively arranged.

[0048] When the detection device described in this embodiment is installed, a scanning area is established at the connection of the front and rear transfer units of the transfer mechanism 6, and the first detection mechanism 1 and the second detection mechanism 2 are fixedly opposed to each other on both sides of the scanning area.

[0049] Among them, as Figure 2 shown, at the top of the support column 7 of the first detection mechanism 1, the first angle adjuster 12 is directly fixedly installed. At the extended end of the movable pin of the first angle adjuster 12, the first transmitter 11 is connected, and the first transmitter 11 faces the transfer mechanism 6. At the top of the support column 7 of the second detection mechanism 2, a control box 8 is installed. As Figure 3 shown, a control circuit board is fixed inside the control box 8. On one side of the top of the control box 8, an L-shaped extended bracket 23 is fixedly installed. At the extended end of the L-shaped extended bracket 23, the second angle adjuster 22 is fixedly installed. At the extended end of the movable pin of the second angle adjuster 22, the second transmitter 21 is connected. The second transmitter 21 and the first transmitter 11 are respectively located on both sides of the scanning area relatively. The first transmitter 11 and the second transmitter 21 respectively emit scanning beams towards the axis of the transfer mechanism 6; on the other side of the control box 8, an alarm lamp 9 is fixedly installed, and the circuit of the alarm lamp 9 is electrically connected to the control circuit board inside the control box 8.

[0050] When the detection device is performing on-line detection work, when the front end of the box 3 to be tested contacts any one scanning beam (or contacts two scanning beams simultaneously) under the push of the transfer roller of the transfer mechanism 6, the on-line detection starts immediately. During the detection process, as the box 3 to be tested advances, the scanning beam scans from the front side to the rear side of the box 3 to be tested. Each scanning point 5 is connected into a scanning line and finally forms an overall scan of the cross-section and each side of the box 3 to be tested. The detection method of using points to represent the surface and the surface to represent the whole is used to realize the scanning detection of the whole cigarette box, so as to determine whether there is a packaging bag 4 on the outside of the box 3 to be tested, so as to realize the precise detection of the bagging state of the box 3 to be tested.

[0051] Based on the above detection device for judging the bagging of the box, this embodiment also provides a cigarette box automatic detection device including the above detection device. This detection device can be directly installed in the detection device and directly installed in the cigarette box production device, so as to realize the on-line detection work of the bagging state of the box 3 to be tested in the cigarette box production process. Its detection process is efficient, the detection result is reliable and the detection data is precise.

[0052] In a preferred embodiment, the detection device further includes an upper system, and a memory for recording the alarm state is installed in the upper system, so as to facilitate the maintenance personnel to statistically analyze and record the operation status of the device.

[0053] Based on the above detection device for judging the bagging of the box body, this embodiment also provides a detection method for judging the bagging of the box body. This detection method can perform bagging detection on the moving box body, so as to complete the continuous detection work of the box body without affecting the transmission of the box body. It will neither affect the normal outbound process in the production of the box body nor can timely warn the box body with unqualified bagging status, so as to remind the operator to replace the unqualified products in time and ensure the quality of the cigarette box when leaving the factory.

[0054] Specifically, this detection method includes:

[0055] S1. Use any pair of relatively emitted scanning beams to establish a scanning area on the conveying mechanism 6 so that the box body 3 to be measured can pass through the scanning area when moving forward;

[0056] S2. When the box body 3 to be measured moves forward and passes through the scanning area, the two scanning beams are respectively emitted to both sides of the box body 3 to be measured, so that continuous scanning points 5 are respectively formed on both sides of the box body 3 to be measured. Use the continuous scanning points 5 to continuously detect the packaging bag on the outer side of the box body 3 to be measured and feedback signals;

[0057] S3. Establish a critical value of the qualified parameter that can determine the qualified state of the box body 3 to be measured, and compare the parameter values of the feedback signals from both sides of the box body 3 to be measured with the critical value of the qualified parameter respectively to obtain comparison result data;

[0058] S4. When the parameter value of any feedback signal is greater than or equal to the critical value of the qualified parameter, judge that the comparison result data is unqualified and start the alarm mechanism.

[0059] In the detection method of this embodiment, the start of the alarm mechanism includes the start of the alarm bell and the start of the alarm light 9, that is, warning is carried out simultaneously from both sound and light aspects.

[0060] In this embodiment, after S4, this detection method further includes:

[0061] S5. Distinguish the parameter comparison results corresponding to each side of the box body 3 to be measured in the comparison result data;

[0062] S6. According to the parameter comparison results, display the bagging status of each side of the box body 3 to be measured in the upper computer system.

[0063] In the detection method of this embodiment, the bagging status of each side of the box body 3 to be measured includes a qualified state and an unqualified state. In other words, the upper computer system in the detection device can intuitively display the bagging status of each side of the box body 3 to be measured. When there is an unqualified state of non-bagging on any side, in addition to the start of the above alarm mechanism, the side of the box body 3 to be measured corresponding to the unqualified state can also be directly shown in the upper computer system, more intuitively displaying the status information of the unqualified products.

[0064] Specifically, the feedback signal in S3 of this detection method includes at least two feedback sub-signals. When ensuring that the scanning point 5 can fall on the front and rear sides of the box 3 to be measured, the feedback signal can include at least four feedback sub-signals.

[0065] Each feedback sub-signal can respectively correspond to each side of the box 3 to be measured. After obtaining the feedback signal, directly distinguish the parameter values of each feedback sub-signal from the feedback signal, and then respectively compare each distinguished feedback sub-signal with the critical value of the qualified parameter, and the parameter comparison result corresponding to the bagging state of each side of the box 3 to be measured can be obtained. And summarizing each parameter comparison result described in S4 is the comparison result data described in S3.

[0066] According to S5 and S6, in the upper computer system, according to each parameter comparison result, display the corresponding bagging state of each side of the box 3 to be measured in the upper computer system, and the side of the box 3 to be measured in the unqualified state can be directly shown in the upper computer system.

[0067] Furthermore, since each scanning beam continuously sweeps across the side of the box 3 to be measured, several consecutive scanning points 5 can be obtained on the side of the box 3 to be measured. Each scanning point 5 can correspondingly provide a feedback sub-signal. According to the above method, the parameter comparison results at different positions on the same side can be obtained. Thus, in the upper computer system, it can also be shown whether the bagging state corresponding to any scanning position on each side is qualified.

[0068] In this embodiment, there are two adjacent conveying units on the conveying mechanism 6, and this detection device is installed at the connection of these two conveying units. The models of these two conveying units are HY206 idler group and HY207 idler group respectively. When the box 3 of cigarettes to be measured travels from the HY206 idler group to the HY207 idler group, the emitting heads 11, 21 on each detection mechanism 1, 2 start to scan the side of the box 3 of cigarettes to be measured through the built-in LR-W amplifier built-in white light point photoelectric sensor, and respectively compare the parameter values of the two groups of feedback signals with the set critical value of the qualified parameter through analysis methods such as spectral analysis.

[0069] In this embodiment, the critical value of the qualified parameter is the threshold value 980. If the parameter value of the above feedback signal is less than 980, it means that the bagging is completed; if the parameter value of the above feedback signal is greater than or equal to 980, it means that the current box 3 of cigarettes is not bagged. It can be understood that the unqualified base value and the critical value of the qualified parameter can be set respectively. For example, the no-bag base parameter (unqualified base value) of the box 3 of cigarettes is preset to 999, and the alarm threshold (critical value of the qualified parameter) is set to 980, and the delay is set to 300 ms, so as to achieve the function of pre-alarm and prevent false detection.

[0070] Report the unqualified detection and comparison results to the control circuit board PLC in the control box 8 through the digital input points, and distinguish the respective unbagged situations on both sides of the box to be tested 3. The control circuit board PLC starts the alarm mechanism on the corresponding side according to the discrimination result of the digital input points, and then the sound and light alarm at the corresponding position can be carried out. This sound alarm is different from other alarm mechanisms of the external transportation system. When the box to be tested 3 is in an abnormal bagging state, the alarm mechanism provides an alarm sound for 200 ms intermittently, while turning on the rotary warning light, and turning it off after a 5-second delay when there is no signal input.

[0071] In summary, the detection device for judging the bagging of the box in this embodiment includes at least a pair of detection mechanisms respectively oppositely arranged on both sides of the conveying mechanism 6. The conveying mechanism 6 is used to drive the box to be tested 3 to pass horizontally between each pair of detection mechanisms; each pair of detection mechanisms respectively oppositely emit scanning light beams, so that each scanning light beam forms a scanning point 5 on both sides of the box to be tested 3. The scanning point 5 is used to detect the packaging bag 4 on the outer side of the box to be tested 3 and feedback signals. This device uses static scanning detection to achieve relative dynamic scanning detection, that is, during the movement of the box to be tested 3, the scanning points 5 falling on both sides of the box to be tested 3 are used to automatically detect and feedback signals on the packaging bag 4 outside the box to be tested 3, so as to realize line scanning formed by point scanning, and further form a plane scan of the box to be tested 3, so as to realize the scanning detection of the overall packaging bag 4 on the outside of the cigarette box, effectively avoiding the quality problem of the cigarette box not being sealed tightly caused by the unbagged cigarette box that cannot be detected in time by manual labor in the prior art, and avoiding the decline of product quality and the waste of production resources caused by the unbagged box to be tested 3 entering the next process.

[0072] This detection device adopts non-contact detection, can be connected to the original production equipment without damage, and automatically detects during the movement of the box to be tested 3. When no unqualified products are found, it will not block the movement of the box to be tested 3, thus not interfering with the normal progress of the original production process, making the cigarette box production line have good production and transportation continuity, and can greatly reduce labor costs.

[0073] This detection device directly detects the appearance of the box to be tested 3, with accurate detection results, high detection efficiency, and the detection data is not easily affected by the unfavorable position of the box to be tested 3. For example, when the box to be tested 3 is tilted or the queue distance changes, it is not easy to have an adverse impact on the detection results.

[0074] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention and design various embodiments adapted to particular uses with various modifications.
