Description

Technical Field

[0001] The invention belongs to the technical field of bottled water, and in particular relates to a method for intelligently removing a bottled water return label and a barrel cover. Background Art

[0002] In the prior art, the working principle of the existing label removal machine is as follows: the solid-state relay is controlled by the temperature sensing controller to start the heating tube device to heat, the barrel clamping device is started to clamp the empty barrel and automatically guide the positioning, the label removal cylinder is started to extend the label removal head device fixed on the label removal cylinder, and the compressed air with a certain pressure is started to control the linear label removal head designed according to the streamline shape of the barrel mouth and barrel cover. The label removal head blows out the hot air beam pressure to form a hot air knife to heat remove the residual barrel neck label, and the removed label is automatically collected through the hot air guide. After the label removal action is completed, the label removal cylinder is retracted, the barrel clamping device is opened, and the work is cyclically performed in sequence.

[0003] This existing label removal machine has some shortcomings, including that the stability of the pressure may be affected by controlling the compressed air at a certain pressure to pass into the linear label removal head designed according to the streamlined shape of the barrel mouth and barrel cover. In actual operation, the pressure of compressed air may change due to fluctuations in the air source (such as changes in the working state of the compressor, pressure loss in the air pipeline, etc.). If the pressure increases suddenly, it may cause damage to the barrel neck; a decrease in pressure will cause insufficient wind power of the hot air knife and incomplete label removal. The nozzle design is not universal. When facing empty barrels with large differences in barrel neck shape, the label removal head may not be able to completely cover the label area, or the fit with the barrel neck is not good enough, so that the hot air knife cannot effectively act on the label, affecting the label removal effect. In addition, regardless of whether the empty barrel has a label or not, it will be delabeled. The hot air directly acts on the barrel neck, which will accelerate the aging of the empty barrel neck, increase energy consumption, and reduce production efficiency.

[0004] In the prior art, the working principle of the existing capping machine is as follows: the empty barrel is transported into the capping machine through a chain path, the barrel clamping device is controlled to clamp the barrel cap, and then the barrel cap is forcibly removed indiscriminately.

[0005] This existing capping machine has some shortcomings. Because the seal design of the barrel lid of the recycled empty barrel is a snap-on type, the capping device fixes the barrel lid at the same height on both sides, and then vertically forces the capping, which will use a large force and easily damage the barrel mouth, causing the loss of the empty barrel. In addition, the capping process generates a large noise, affecting the working environment. In addition, whether the empty barrel has a barrel lid or not, the capping operation will be performed on it. The capping device clamps the barrel mouth, which will damage the barrel mouth, increase energy consumption, and reduce production efficiency. Summary of the invention

[0006] In order to overcome the shortcomings of the prior art, the present invention provides a method for intelligently removing bottled water return barrel labels and barrel covers, so as to solve the problems of the prior art in which the neck of the hollow barrel undergoes an indiscriminate hot label removal process and a forced lid removal process, resulting in aging and damage of the barrel neck and barrel mouth, as well as high energy consumption.

[0007] The present invention provides an embodiment, including a method for intelligently removing the label and barrel cover of bottled water returning to the barrel, the method comprising at least the following steps: step one: detecting the residual label of the returned barrel, and controlling the execution action of the label removal device according to the residual label situation of the returned barrel; step two: detecting the barrel cover of the returned barrel, and controlling the execution action of the cap removal device according to the situation of the barrel cover of the returned barrel.

[0008] In one of the embodiments, the detection of whether there is a label and a barrel cover on the returned barrel includes: acquiring a high-resolution image of the label position on the barrel neck of the returned barrel through a visual recognition system, and using a pattern recognition algorithm to identify whether there is a residual label on the returned barrel corresponding to the acquired high-resolution image, and determining the position, area, and degree of damage of the residual label; and, identifying whether there is a barrel cover on the returned barrel through a photoelectric sensor.

[0009] In one of the embodiments, the label removal equipment includes a label removal head device and a barrel clamping device, the label removal head device includes at least three label removal heads distributed in an array, and the label removal heads are configured to form a hot air knife by blowing out hot air beam pressure; the method for intelligently removing the label of bottled water returning to the barrel includes: when the barrel runs to the equipment, the barrel clamping device of the equipment clamps the empty barrel and runs forward, the label removal head determines the position of the barrel mouth according to the sensing signal, performs automatic guidance and positioning, and runs forward at the same speed and direction, and uses the hot air knife blown out by the label removal head to melt and cut off the label, so as to achieve the purpose of removing the residual label.

[0010] In one of the embodiments, the at least three array-distributed label removal heads are arranged in the middle and lower parts, and can adjust the number of label removal heads started in real time according to the size and height of the residual labels on the barrel mouth, so as to achieve intelligent control and reduce energy consumption.

[0011] In one of the embodiments, the label removal device further comprises a heat pipe device and at least one temperature sensing controller, wherein the temperature sensing controller is configured to control the temperature of the heat pipe device.

[0012] In one of the embodiments, the device for intelligently removing the bottled water return label also includes: determining the heating temperature of the heating tube device and controlling the temperature deviation range; controlling the start and stop of the barrel clamping device according to the feedback signal of the temperature sensing controller, and when the temperature deviation exceeds the set temperature range, the barrel clamping device stops running and starts the sound and light alarm to alarm.

[0013] In one of the embodiments, the control cap removal device comprises two adjustable clamping arms; the control cap removal device performs cap removal, comprising: controlling the two adjustable clamping arms to be fixed at upper and lower positions on both sides of the barrel cover to perform staggered cap removal.

[0014] In one of the embodiments, the control of the capping device to perform capping further includes: by setting the diameter parameter of the barrel cover, the two adjustable clamping arms automatically adjust the clamping force applied to the barrel cover to perform the offset capping action.

[0015] In one of the embodiments, a sensor is provided on the clamping arm for detecting the clamping force, so as to prevent damage to the barrel mouth caused by excessive clamping.

[0016] In one of the embodiments, maintaining the silent state of the label removal device and the cap removal device includes: if it is detected that there is no residual label or barrel cover in the return barrel, the label removal device and the cap removal device are not started, or the label removal action and the cap removal action are not performed.

[0017] The present invention also provides an embodiment including an electronic device, the electronic device including a memory and a processor, the memory storing a computer program, and the processor implementing any one of the method steps for intelligently removing the bottled water return barrel label and barrel cover when executing the computer program.

[0018] The method for intelligently removing the bottled water return barrel label and barrel cover provided in the above embodiment has the following beneficial effects:

[0019] The present invention can accurately identify the residual label on the barrel neck of the returned barrel through the visual recognition module, so that the operation of the label removal machine can be accurately controlled according to the presence and position of the actual label, avoiding the waste of resources and unnecessary operations caused by indiscriminate activation of the label removal machine. If there is a label, the different label removal heads of the label removal machine are activated to remove it. If there is no label, the empty barrels are reasonably diverted, which greatly improves the overall work efficiency, effectively shortens the processing time of a single empty barrel in the label removal link, and speeds up the recycling process of bottled water returning to the barrel.

[0020] The traditional indiscriminate heat label removal process easily causes the neck of the empty barrel to age due to excessive heat. The present invention flexibly controls the label removal machine to start different parts of the label removal head according to the height size of the residual label on the barrel mouth. In this way, the label can be accurately removed, avoiding ineffective heating or excessive treatment of the label-free area, minimizing unnecessary thermal stress on the neck of the empty barrel, effectively reducing the aging problem of the neck of the empty barrel caused by indiscriminate heat label removal, extending the service life of the empty barrel, and saving the cost of frequent replacement of empty barrels for bottled water companies.

[0021] By accurately identifying the barrel mouth and starting different parts of the equipment accordingly, unnecessary operation time is reduced and the speed of label removal and lid removal is increased. It avoids starting high-power equipment when it is not necessary, effectively reduces energy consumption, and meets the requirements of energy conservation and environmental protection. Only starting specific parts of the equipment when necessary reduces equipment wear and failure rate and extends the service life of the equipment. Whether it is packaging barrels of different sizes and shapes, or packaging barrels with different label residues and barrel lid conditions, they can all be efficiently processed through flexible control.

[0022] The overall process is highly intelligent. The visual recognition module and the label removal equipment work together to automatically adjust the label removal strategy according to different return barrel label conditions. Whether the label is located in different positions on the barrel neck or some empty barrels are unlabeled, they can be properly handled; the barrel cover removal equipment contains multiple components, using photoelectric sensing and control systems. When there is a barrel cover, the cover removal operation is started, and when there is no barrel cover, it remains silent. This can accurately control the cover removal process to ensure safety and stability, and can also avoid energy consumption and equipment wear, effectively increase the service life of the equipment, and help improve overall operating efficiency and economy. This intelligent and flexible processing method enables it to adapt well to the complex situations of return barrel labels in various actual production scenarios, ensuring the stable and efficient operation of the barrel water return barrel label removal process.

[0029] Example 1

[0030] The working principle of the existing label removal machine is: the solid-state relay is controlled by the temperature sensing controller to start the heating tube device for heating. When the empty barrel neck is detected to have residual labels, the barrel clamping device is started to clamp the empty barrel and automatically guide it to position. The label removal cylinder is started to extend the label removal head device fixed on the label removal cylinder. The compressed air with a certain pressure is started to pass into the linear label removal head designed according to the streamline shape of the barrel mouth and barrel cover. The label removal head blows out the hot air beam pressure to form a hot air knife to heat remove the residual barrel neck label, and the removed label is automatically collected through the hot air guide. After the label removal action is completed, the label removal cylinder is retracted, the barrel clamping device is opened, and the work is cyclically performed in sequence.

[0031] The working principle of the existing capping machine is as follows: the empty barrels are transported to the capping machine through a chain, the barrel clamping device is controlled to clamp the barrel cap, and then the barrel cap is forcibly removed indiscriminately.

[0032] refer to Figure 1In order to solve the above problems, one of the embodiments of the present invention provides a method for intelligently removing the label and barrel cover of bottled water returning to the barrel, the method detects whether there is a residual label on the return barrel; if so, controls the label removal device to remove the return barrel label, if not, maintains the label removal device in a silent state. The method detects whether there is a barrel cover on the return barrel; if so, controls the cap removal device to remove the cap; if not, maintains the cap removal device in a silent state. The present invention identifies the residual label on the barrel neck through a visual recognition system, and determines the heating temperature and the control temperature deviation range according to the recognition result, so as to adaptively match at least one of the three array-distributed label removal heads, and automatically adjusts the position and angle of the label removal head to remove the residual label. The present invention identifies the barrel cover through a photoelectric sensing system, and determines whether to start the clamping arm to remove the cap according to the recognition result.

[0033] In this embodiment, the method steps include step 1: detecting the residual label of the returned barrel, and controlling the execution action of the label removal device according to the residual label of the returned barrel; step 2: detecting the barrel cover of the returned barrel, and controlling the execution action of the cover removal device according to the barrel cover of the returned barrel.

[0034] In some embodiments, a high-precision visual recognition module is installed, which can accurately detect whether there are residual labels on the barrel neck of the return barrel. The visual recognition system consists of a high-definition camera, an image processor and an intelligent algorithm. The camera is installed in a suitable position to ensure that the key parts of the return barrel can be clearly photographed. The image processor can quickly process the image data collected by the camera, and determine the presence of labels through intelligent algorithm analysis. In order to ensure the accuracy and stability of the visual recognition module, it needs to be calibrated and maintained regularly. Calibration can be performed by using a standard return barrel sample, adjusting the focal length, angle and image parameters of the camera to ensure that the label can be accurately identified. Maintenance includes cleaning the camera lens, checking the operating status of the image processor and updating the intelligent algorithm to adapt to different types of return barrels and labels.

[0035] The above intelligent algorithm steps, by training the CNN model, the system can automatically extract features from the image and determine whether the empty bottle of bottled water has a label. The specific steps are as follows: the input bottled water image is scaled, grayed, and processed to meet the input requirements of the model; then the image data marked as "label present" or "label missing" is used for training. During the training process, CNN automatically learns the local features in the image (such as the shape, color, position, etc. of the label). After the training is completed, a new image is input, and the model will output the judgment result of whether it contains a label.

[0036] For the detection of the label position in the bottled water image, an object detection algorithm can be used. This algorithm can detect the label area in the image and determine whether the label exists. A target detection model is trained with a given image dataset to learn how to locate and classify labels. The model detects the label area in the image and returns the label's bounding box) and its confidence. If the label box position output by the model matches the label area, the label is considered to exist; otherwise, the label is considered to be missing.

[0037] In this embodiment, the YOLO target detection model can be selected. According to the formula,

[0038] pi = σ (box score)

[0039] x i =σ(grid x )

[0040] y i =σ(grid -y )

[0041] w i =width_predict

[0042] h i =height_predictσ is the Sigmoid activation function, box s core represents the confidence of the box, grid x and grid y is the coordinate of each grid, width p redict and height p redict is the width and height of the predicted label box.

[0043] According to the above algorithm formula, the features of the label can be automatically learned from the image through the training model, and effective judgment can be made, so as to effectively and accurately judge the detection label position and perform label removal.

[0044] The system acquires high-resolution images of the label position on the return barrel neck, and uses a pattern recognition algorithm to identify whether there are any residual labels on the return barrel corresponding to the acquired high-resolution image, as well as to determine the position, area, and degree of damage of the residual labels; and, uses a photoelectric sensor to identify whether there is a return barrel lid.

[0045] In one embodiment, the label removal device includes a label removal head device and a barrel clamping device, the label removal head device includes at least three label removal heads distributed in an array, and the label removal heads are configured to form a hot air knife by blowing out a hot air beam pressure; the method for intelligently removing the label of the bottled water returning to the barrel includes: when the barrel runs to the device, the barrel clamping device of the device clamps the empty barrel and runs forward, the label removal head determines the position of the barrel mouth according to the sensing signal, performs automatic guidance and positioning, and runs forward at the same speed and direction, and uses the hot air knife blown out by the label removal head to melt and cut off the label, so as to achieve the purpose of removing the residual label. The conveying chain automatically delivers the empty barrel after the label is removed to the capping place, and the automatic detection mechanism at the capping place detects the signal and controls the capping machine to pull off the barrel cap, so as to achieve the purpose of removing the barrel cap.

[0046] In some embodiments, the label removal device is composed of a heating device, a label removal head and a control system. The heating device adopts advanced heating technology, which can quickly heat up and maintain a stable temperature. The label removal heads are designed in an array distribution, with a total of three, corresponding to the upper, middle and lower parts of the barrel neck. Each label removal head can be independently controlled and can automatically adjust the position and angle according to the results of the visual recognition module to ensure that the residual label can be accurately removed.

[0047] In one embodiment, the label removal device further comprises a heating tube device and at least one temperature sensing controller, wherein the temperature sensing controller is configured to control the temperature of the heating tube device. The device for intelligently removing the label of bottled water returning to the barrel further comprises: determining the heating temperature of the heating tube device and controlling the temperature deviation range; controlling the start and stop of the barrel clamping device according to the feedback signal of the temperature sensing controller, and when the temperature deviation exceeds the set temperature range, the barrel clamping device stops running and starts the sound and light alarm to alarm.

[0048] The temperature controller plays a vital role in this intelligent method of removing the labels and lids of barrels of bottled water. The temperature controller can set the heating temperature on demand, which enables the system to accurately adjust the degree of heating according to different types of labels and materials. For example, for some labels that are difficult to remove, the heating temperature may need to be set higher to ensure that the labels are fully melted and cut off; while for labels with thinner materials, the temperature may need to be set relatively low to avoid deformation or damage to the barrel neck due to heat.

[0049] The temperature controller is also able to control the temperature deviation range. This means that it can ensure that the actual heating temperature always fluctuates within a certain range of the set temperature. For example, if the set temperature is 100 degrees Celsius and the deviation range is set to ±5 degrees Celsius, then when the actual temperature is between 95 degrees Celsius and 105 degrees Celsius, the system considers the temperature to be within the normal range. This ensures the stability and consistency of the heating process and improves the effect of label removal.

[0050] When the temperature deviation is lower or higher than the set range, the temperature controller will output a feedback signal. This feedback signal has three important functions: first, it controls the barrel clamping device to extend the barrel clamping device and stop the barrel passing through the production line to prevent unqualified barrels from continuing to enter the subsequent process, thereby ensuring the quality of the entire production process; second, it automatically corrects the temperature. When the temperature deviates, it controls the heating module to work or not work; third, it activates the sound and light alarm to warn the staff to deal with the abnormal temperature in time to avoid further expansion of the problem.

[0051] The specific steps of the embodiment provided by the present invention include detecting whether there are residual labels on the returned barrel: when the returned barrel enters the processing area, the visual recognition system first photographs and identifies the barrel neck of the returned barrel to detect whether there are residual labels. If the visual recognition module detects that there are residual labels on the barrel neck of the returned barrel, it will send a signal to the control system of the label removal device. After receiving the signal, the control system will start the label removal head according to the position and size of the label and blow out a hot air knife to achieve the purpose of removing the label.

[0052] Control the label removal equipment to remove the return label: The control system pre-sets the heating temperature and temperature deviation range. After determining the heating temperature and the control temperature deviation range, the control system will start the heating device of the label removal equipment to raise the temperature to the set level. At the same time, the control system will automatically adjust the position and angle of the label removal head according to the results of the visual recognition system to match the position and size of the residual label.

[0053] When the heating temperature working step needs to be accurately measured or controlled under different temperature conditions, the temperature compensation formula and control method of the heating module need to be considered in the process of automatic temperature correction. The typical control method is to use the temperature error to adjust the heating power. Assuming that the temperature response of the module is affected by factors such as ambient temperature, heating power, and heat conduction, common compensation and adjustment methods can be achieved in the following ways.

[0054] First, we need to establish a temperature correction model according to the formula:

[0055] P T =P0(1+α·(T-T0))

[0056] , P T is the required heating power at temperature T. P0 is the heating power at reference temperature T0; α is the temperature compensation coefficient of the heating system; T is the current temperature. T0 is the set or reference temperature. Through this formula, the heating power can be adjusted at different temperatures to ensure that the heating module can work stably when the temperature changes.

[0057] When the heating device reaches the set temperature, the control system will start the label remover and remove the residual label close to the barrel neck. The label remover will blow out a hot air knife to melt and cut off the label. During the label removal process, the control system will monitor the heating temperature and the position of the label remover in real time to ensure that the temperature is within the control range and that the label remover can accurately remove the label.

[0058] If the visual recognition module detects that the label is present in multiple locations of the top, middle, and bottom of the barrel neck, the control system will automatically activate the corresponding label removal heads and work simultaneously to improve the removal efficiency. If the label is only present in a specific location, the control system will only activate the corresponding label removal head to avoid unnecessary energy waste and equipment wear.

[0059] Maintain the label removal device in a silent state: If the visual recognition module detects that there is no residual label on the barrel neck, the control system will maintain the label removal device in a silent state and not perform any operation. This can avoid unnecessary energy consumption and equipment wear, and also increase the service life of the equipment.

[0060] In some embodiments, the barrel cover removal device is composed of a frame, a cover removal device, a cover blowing device, and a conveyor chain. After the label removal operation is completed, the empty barrel is moved to the cover removal device, and the photoelectric sensing system will sense and identify the returned barrel to detect whether there is a barrel cover. If it is detected that the returned barrel has a barrel cover, a signal will be sent to the control system of the cover removal device. After receiving the signal, the control system will start the cover removal device to perform the cover removal operation.

[0061] Control the uncapping device to uncap. If the photoelectric sensing system detects that there is a barrel cap on the return barrel, the control system will start the uncapping device to uncap. The empty barrel fixing device of the uncapping device will fix the return barrel, the clamp will extend to clamp the barrel cap, and then pull out the barrel cap through mechanical force. During the uncapping process, the control system will monitor the position and force of the mechanical arm and clamp in real time to ensure the safety and stability of the uncapping process.

[0062] Maintain the silent state of the capping device: If the visual recognition system detects that there is no barrel cap when the barrel is returned, the control system will maintain the silent state of the capping device and will not perform any operation. This can avoid unnecessary energy consumption and equipment wear, and also increase the service life of the equipment.

[0063] In some embodiments, a control system is also included. The control system is the core part of the label removal device. It can receive signals from the visual recognition system and control the operation of the heating device and the label removal head according to the signals. The control system uses advanced microprocessors and control algorithms to achieve precise temperature control and position adjustment of the label removal head. At the same time, the control system also has fault diagnosis and alarm functions, which can detect equipment failures in a timely manner and take corresponding measures.

[0064] The control system can set the data of the barrel clamping device's extension positioning time, the label removal header extension time, and the label removal header hot air beam pressure blowing time. The barrel clamping device's extension positioning time can be set through programming. The operator can input the required time parameters on the control system interface according to the actual situation, and the control system will control the barrel clamping device's action according to this parameter. The operator can also adjust the label removal header extension time parameter according to the specific conditions of the barrel type and production line speed. The control system will control the label removal header action according to this parameter to ensure that the label removal header is extended at the right time to complete the label removal task. Then, the label removal header hot air beam pressure blowing time can be set by adjusting the pressure and flow of the hot air source and controlling the length of the blowing time. The operator adjusts the relevant parameters in the control system according to the specific conditions of the label and the production line speed. The control system will control the pressure and blowing time of the hot air beam according to these parameters to achieve the best label removal effect.

[0065] In one embodiment, the label removal device includes a label removal head device and a barrel clamping device, the label removal head device includes at least three label removal heads distributed in an array, and the label removal heads are configured to form a hot air knife by blowing out a hot air beam pressure; the method for intelligently removing the label of bottled water returning to the barrel includes: when the barrel runs to the device, the barrel clamping device of the device clamps the empty barrel and runs forward, the label removal head determines the position of the barrel mouth according to the sensing signal, performs automatic guidance positioning, and runs forward at the same speed and direction, and uses the hot air knife blown out by the label removal head to melt and cut off the label, so as to achieve the purpose of removing the residual label. The at least three label removal heads distributed in the array are arranged in the middle and lower parts, and can adjust the number of label heads in real time to cooperate with the work according to the size and height of the residual label on the barrel mouth identified.

[0066] When the barrel runs to the equipment, the barrel clamping device first works, clamping the empty barrel and moving forward. At this time, the label removal head determines the position of the barrel mouth according to the sensing signal and automatically guides and locates. This sensing signal may come from a sensor, such as a photoelectric sensor or a proximity sensor, which can detect the position of the barrel and the characteristics of the barrel mouth, providing accurate positioning information for the label removal head.

[0067] After positioning is completed, the label removal head runs forward at the same speed and direction as the empty barrel, while blowing out the hot air knife. The temperature and pressure of the hot air knife are carefully adjusted to effectively melt the label and cut off the label through the impact force of the hot air. In this way, the label can be separated from the barrel mouth, achieving the purpose of removing the residual label. According to the size and height of the residual label on the barrel mouth identified, the number of label removal heads is adjusted in real time to work together. For example, if the visual recognition system detects that the label covers the upper, middle and lower parts of the barrel mouth, then the three label removal heads can be started at the same time to remove the label with maximum efficiency. If the label only exists in the upper or lower part of the barrel mouth, the label removal head at the corresponding position will work alone, and the other label removal heads will remain silent.

[0068] In one of the embodiments, maintaining the silent state of the label removal device and the cap removal device includes: if it is detected that there is no residual label or barrel cover in the return barrel, the label removal device and the cap removal device are not started, or the label removal action and the cap removal action are not performed.

[0069] The capping equipment consists of an empty barrel fixture, a fixture and a control system. The fixture can fix the barrel back, and the fixture can firmly clamp the barrel lid and pull it out. The control system can receive signals from the visual recognition system and control the work of the fixture and fixture according to the signals. The control system uses advanced microprocessors and control algorithms to achieve precise position control and force control to ensure the safety and stability of the capping process.

[0078] The present invention can accurately identify the residual label on the barrel neck of the returned barrel through the visual recognition module, so that the operation of the label removal machine can be accurately controlled according to the actual presence and position of the label, avoiding the waste of resources and unnecessary operations caused by indiscriminate activation of the label removal machine. If there is a label, the label removal machine is activated to remove it; if not, the empty barrels are reasonably diverted, which greatly improves the overall work efficiency, effectively shortens the processing time of a single empty barrel in the label removal link, and speeds up the recycling process of bottled water returning to the barrel.

[0079] The traditional indiscriminate hot label removal process and clamping of the barrel mouth can easily cause the neck of the empty barrel to age due to excessive heat, and the clamp scratches the barrel mouth, reducing the sealing of the barrel mouth and causing the empty barrel to be scrapped. The present invention flexibly controls the different parts of the label removal head of the label removal machine to start, and flexibly controls whether the capping machine is started, based on the height size of the residual label on the barrel mouth and whether there is a barrel cover. In this way, the label and barrel cover can be accurately removed, and ineffective heating or excessive treatment of the unlabeled area and indiscriminate treatment of the barrel cover can be avoided, which minimizes the unnecessary thermal stress and barrel mouth scratch problems on the neck of the empty barrel, effectively reduces the aging problem of the empty barrel neck caused by indiscriminate hot label removal and the problem of the empty barrel being scrapped due to the clamp scratching the barrel mouth, and extends the service life of the empty barrel, saving the cost of frequent replacement of empty barrels for bottled water companies.

[0080] The overall process is highly intelligent. The visual recognition module works in coordination with the label removal, and the sensing device works in coordination with the barrel cover removal equipment. The label removal and cover removal strategies can be automatically adjusted according to the different barrel return labels and barrel cover conditions. Whether the labels are located at different positions on the barrel neck, or some empty barrels are without labels or barrel covers, they can be properly handled. This intelligent and flexible processing method enables it to adapt well to the complex situations of barrel return labels and barrel covers in various actual production scenarios, ensuring the stable and efficient operation of the barrel return label and barrel cover removal process for bottled water.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
