[0002] With the further development of industrial technology, the automation level of equipment in major domestic cigarette companies has been further improved, and the amount of physical labor of workers in cigarette production workshops will be further reduced in the future. In the process of cigarette production, the continuous and stable supply of cigarette paper and tipping paper is crucial. Traditional cigarette production still requires manual replacement of paper trays, and then manually introducing paper tapes into the equipment.

[0067] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0068] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0069] Please refer to Figures 1 to 4 ,in, Figure 1 A schematic diagram of a paper coil and paper feeding device provided in an embodiment of the present application, Figure 2 A schematic diagram of a connecting plate provided in an embodiment of the present application, Figure 3 A schematic diagram of a paper clamping mechanism provided in an embodiment of the present application, Figure 4 A schematic diagram of a paper tray contact rod and a clamping rod provided in an embodiment of the present application.

[0070] In a first specific implementation manner, the paper coil and paper guiding device provided in the embodiment of the present application includes a connecting plate 1 and a paper clamping mechanism 2, wherein the connecting plate 1 is used to be connected to a robot; the paper clamping mechanism 2 is arranged on the connecting plate 1, and the paper clamping mechanism 2 includes a paper tray contact rod 201, a paper tray sensing component 202 and a clamping rod 203, wherein the paper tray contact rod 201 is used to contact the paper tray; the paper tray sensing component 202 is used to detect the contact state between the paper tray contact rod 201 and the paper tray, and send a signal to the robot to adjust the position of the paper coil and paper guiding device through the robot; the clamping rod 203 is used to clamp the paper coil (the paper tape wound on the paper tray) together with the paper tray contact rod 201.

[0071] In the tobacco industry's rolling and splicing equipment, traditional paper threading operations are mainly completed manually, which has many shortcomings, such as low efficiency, difficulty in ensuring accuracy, high labor intensity, and certain safety hazards. In response to these problems, the present application provides a paper coil threading device, which aims to significantly improve the efficiency and accuracy of paper threading operations through automated and intelligent design, while reducing labor intensity.

[0072] The paper coil and paper guiding device provided in the present application includes a connecting plate 1 and a paper clamping mechanism 2. The connecting plate 1 is used to connect with the robot so that the entire device can be seamlessly connected with the robot system on the automated production line, thereby realizing automated operation. The paper clamping mechanism 2 is arranged on the connecting plate 1, and its core components include a paper tray contact rod 201, a paper tray sensing component 202 and a clamping rod 203. The paper tray contact rod 201 is used to contact the paper tray and is a direct component for realizing the paper tray and paper guiding operation. The paper tray sensing component 202 is used to detect the contact state between the paper tray contact rod 201 and the paper tray, and can send a signal to the robot. This function is crucial because it allows the robot to adjust the position of the paper coil and paper guiding device in real time according to the signal fed back by the paper tray sensing component 202, ensuring that the paper tray contact rod 201 can accurately contact the paper tray and perform subsequent paper guiding operations. The clamping rod 203 is used to clamp the paper coil together with the paper tray contact rod 201, so as to facilitate the subsequent paper guiding action through the robot.

[0073] In combination with the above structure and process description, it can be seen that the paper coil and paper feeding device has at least the following beneficial effects: the paper coil and paper feeding device can detect the contact status between the paper tray contact rod 201 and the paper tray in real time by setting the paper tray sensing component 202 and send a signal to the robot, thereby achieving precise positioning and clamping, effectively improving paper feeding efficiency and accuracy, reducing manual intervention, reducing labor intensity, and at the same time improving the continuity and stability of production.

[0074] In some embodiments, the connecting plate 1 is provided with a bearing 101; the paper clamping mechanism 2 further includes:

[0075] The swing rod 204 is rotatably mounted on the connecting plate 1 through the bearing 101, and the swing rod 204 is connected to the paper tray contact rod 201;

[0076] Wherein, the paper tray sensing component 202 includes:

[0077] A swing piece 2021, provided on the swing rod 204;

[0078] The sensor 2022 is used to detect the position of the pendulum 2021 .

[0079] In this embodiment, the connecting plate 1, as an important component of the paper coiling and threading device, can be designed to be connected to the quick-change joint of the robot's mechanical arm, for example, a hole for connection is provided on the connecting plate 1. In addition, the connecting plate 1 is provided with a bearing 101 on the other side connected to the robot. In particular, the upper part of the connecting plate 1 is connected to the robot, and the bearing 101 is provided on the lower part.

[0080] This design enables the entire device to be more flexibly connected and coordinated with a robot or other automated equipment. Through the arrangement of the bearing 101, the connecting plate 1 can not only provide stable support, but also ensure the stability and reliability of the device during operation.

[0081] In this embodiment, the paper clamping mechanism 2 further includes a swing rod 204. The swing rod 204 is rotatably disposed on the connecting plate 1 through the bearing 101, and is connected to the paper tray contact rod 201. This structural design enables the paper tray contact rod 201 to achieve flexible rotation and position adjustment driven by the swing rod 204. When the paper tray contact rod 201 contacts the paper tray, the swing rod 204 can adjust the angle and position of the paper tray contact rod 201 through the rotation of the bearing 101 according to the position and state of the paper tray, thereby better adapting to paper trays of different specifications and states, and ensuring the smooth progress of the paper feeding operation.

[0082] In this embodiment, the paper tray sensing component 202 is one of the key parts of the paper clamping mechanism 2. It includes a swing piece 2021 and a sensor 2022. The swing piece 2021 is set on the swing rod 204 and moves synchronously with the swing rod 204. The sensor 2022 is used to detect the position of the swing piece 2021. When the paper tray contact rod 201 contacts the paper tray and drives the swing rod 204 to rotate, the position of the swing piece 2021 will also change accordingly. By detecting the position change of the swing piece 2021, the sensor 2022 can sense the contact state between the paper tray contact rod 201 and the paper tray in real time and feed this information back to the control system. This design enables the robot or other automated equipment to adjust the position and posture of the paper coil and paper feeding device in time according to the feedback signal to ensure the accuracy and reliability of the paper feeding operation. Through this intelligent sensing and feedback mechanism, the device can effectively improve the efficiency and accuracy of paper feeding, reduce manual intervention, reduce labor intensity, and improve the continuity and stability of production.

[0083] Optionally, the swing rod 204 and the paper tray contact rod 201 are in a rotational relationship, and the swing rod 204 and the swing piece 2021 are in a fixed relationship; the paper tray contact rod 201 is located at the head end of the swing rod 204, and the swing piece 2021 is located at the tail end of the swing rod 204; the sensor 2022 adopts a slot-type photoelectric sensor.

[0084] Please continue to refer to Figure 3 In some embodiments, the paper clamping mechanism 2 further includes:

[0085] Support seat 205;

[0086] The adjusting knob 206 is threadedly connected to the supporting base 205;

[0087] The spring 207 has a first end connected to the adjusting knob 206 and a second end connected to the swing rod 204 . The length of the spring 207 is adjusted by rotating the adjusting knob 206 .

[0088] In this embodiment, the paper clamping mechanism 2 further includes a support seat 205, an adjustment knob 206 and a spring 207. As an important component of the paper clamping mechanism 2, the support seat 205 provides a stable installation base for other components and ensures the structural stability of the entire mechanism. The adjustment knob 206 is connected to the support seat 205 by a threaded connection. This connection method enables the adjustment knob 206 to be rotated and adjusted on the support seat 205, thereby achieving fine adjustment of the mechanism.

[0089] One end of the spring 207 is connected to the adjustment knob 206, and the other end is connected to the swing rod 204. By rotating the adjustment knob 206, the length of the spring 207 can be changed, thereby adjusting the elastic force of the spring 207. This design enables the paper clamping mechanism 2 to flexibly adjust the force state of the swing rod 204 according to actual operation requirements. When it is necessary to increase the stability of the swing rod 204 or adjust the sensitivity of its movement, it can be achieved by rotating the adjustment knob 206. This adjustable design not only improves the adaptability and flexibility of the paper clamping mechanism 2, but also ensures that the contact state between the paper tray contact rod 201 and the paper tray can be accurately controlled under different working conditions, thereby further improving the reliability and stability of the paper feeding operation.

[0090] In some cases, the bearing 101, the paper tray contact rod 201, the swing piece 2021, the sensor 2022, the swing rod 204, the support seat 205, the adjustment knob 206 and the spring 207 form a paper tray sensing mechanism, which is used to sense the contact with the paper tray and send a signal to the outside by continuously approaching the paper tray. The mechanism is exquisitely designed and simple in structure, and plays the role of sensing and adjusting the contact force, and has the function of amplifying.

[0091] The specific functional implementation includes two aspects: perception and regulation.

[0092] For perception, the collaborative robot moves the paper-coiling and paper-feeding device closer to the paper tray, so that the paper tray contact rod 201 moves closer to the paper tray, thereby contacting the paper tray. At this time, the paper tray contact rod 201 continues to approach the paper tray, so that the paper tray contact rod 201 is subjected to contact force, and the paper tray contact rod 201 is connected to the swing rod 204, driving the swing rod 204 to rotate counterclockwise around the bearing 101. Since the swing piece 2021 is fixed to the end of the swing rod 204, the swing piece 2021 will be displaced immediately, so that it rotates into the slot-type photoelectric sensor 2022, thereby triggering the sensor 2022 to send a signal, indicating that the paper tray has been contacted.

[0093] For adjustment, after the paper tray contact rod 201 contacts the paper tray, the contact force given by the paper tray to the paper tray contact rod 201 is transmitted to the swing rod 204, and the premise for the swing rod 204 to rotate is to offset the pulling force brought by the spring 207. By rotating the adjustment knob 206 to move it toward the spring 207, the sensing critical value can be reduced, and vice versa.

[0094] In some embodiments, the paper clamping mechanism 2 further includes:

[0095] The proximity switch 212 is disposed on the rocker rod 204 , and is used to detect the position of the clamping rod 203 .

[0096] In this embodiment, the paper clamping mechanism 2 further includes a proximity switch 212, which is mounted on the swing rod 204. The proximity switch 212 is used to detect the position of the clamping rod 203, which is very important for the normal operation of the entire paper coiling and threading device.

[0097] Specifically, the function of the sensor 2022 is to detect whether the paper tray contact rod 201 is in contact with the paper tray, so as to prepare for the subsequent paper coil clamping operation. When the sensor 2022 detects that the paper tray contact rod 201 has contacted the paper tray, it will send a signal to the robot to inform the robot that the paper tray is in place and the next operation can be performed. However, it is not enough to just detect the contact between the paper tray contact rod 201 and the paper tray. It is also necessary to ensure that the paper coil can be clamped correctly for the subsequent paper feeding operation. The clamping position is not limited here. For example, the paper coil can be clamped at the unsealing position.

[0098] At this time, the role of the proximity switch 212 is particularly important. The proximity switch 212 can determine whether the paper roll has been successfully clamped by the clamping rod 203 and the paper tray contact rod 201 by detecting the position of the clamping rod 203. If the proximity switch 212 detects that the clamping rod 203 is in the correct position, it means that the paper roll has been clamped, and the device can continue to perform subsequent paper feeding operations; on the contrary, if the proximity switch 212 detects that the position of the clamping rod 203 is incorrect, it means that the paper roll may not be clamped correctly, and the robot can adjust the position of the paper clamping mechanism 2 or perform other necessary operations accordingly to ensure that the paper roll can be clamped correctly.

[0099] Through the coordinated work of the sensor 2022 and the proximity switch 212, the paper coiling and paper feeding device can realize dual detection of the paper coil contact state and the paper coil clamping state, thereby ensuring the accuracy and reliability of the paper feeding operation. This design not only improves the automation level of the device, but also effectively reduces production failures caused by inaccurate clamping, further improving the continuity and stability of production.

[0100] In some embodiments, the paper tray contact rod 201 and the clamping rod 203 are both rotatably mounted on the swing rod 204;

[0101] The paper clamping mechanism 2 also includes:

[0102] A contact torsion spring 208, provided on the paper tray contact lever 201;

[0103] A clamping torsion spring 209, provided on the clamping rod 203;

[0104] The elastic forces of the contact torsion spring 208 and the clamping torsion spring 209 drive the paper tray contact rod 201 and the clamping rod 203 to move toward each other.

[0105] In this embodiment, the paper tray contact rod 201 and the clamping rod 203 are both rotatably arranged on the swing rod 204. This structural design enables the paper tray contact rod 201 and the clamping rod 203 to flexibly adjust the position and angle to meet the needs of paper trays of different specifications and paper feeding operations. In order to realize the automatic clamping function, the paper clamping mechanism 2 further includes a contact torsion spring 208 and a clamping torsion spring 209.

[0106] The contact torsion spring 208 is installed on the paper tray contact rod 201, and the clamping torsion spring 209 is installed on the clamping rod 203. The function of these two torsion springs is to use their elastic force to drive the paper tray contact rod 201 and the clamping rod 203 to move toward each other, which can not only automatically clamp the paper, but also achieve interlocking under the action of the two elastic forces. Specifically, the contact torsion spring 208 will generate an elastic force to push the paper tray contact rod 201 to move toward the clamping rod 203. At the same time, the clamping torsion spring 209 will also generate an elastic force to move the clamping rod 203 toward the paper tray contact rod 201. Through the mutual cooperation of such elastic forces, the paper tray contact rod 201 and the clamping rod 203 can automatically clamp the paper, complete the clamping action, and achieve interlocking.

[0107] This design not only improves the degree of automation of clamping, but also ensures the rapidity and reliability of the clamping action. Through the elastic force of the torsion spring, the paper tray contact rod 201 and the clamping rod 203 can quickly complete the clamping action after contacting the paper tray, without the need for an additional power device or a complex control mechanism, thereby simplifying the structure of the entire paper clamping mechanism 2, reducing costs, and improving the stability and durability of the device.

[0108] Please refer to Figure 5 , Figure 5 A schematic diagram of a clamping torsion spring provided in an embodiment of the present application.

[0109] In some embodiments, the paper clamping mechanism 2 further includes:

[0110] The torsion spring limiting seat 210 is connected to the first end of the clamping torsion spring 209;

[0111] The clamping adjustment member 211 is connected to the second end of the clamping torsion spring 209 , and the torque of the clamping torsion spring 209 can be adjusted by rotating the clamping adjustment member 211 .

[0112] In this embodiment, the paper clamping mechanism 2 further includes a torsion spring limit seat 210 and a clamping adjustment member 211. These two components are used in conjunction with the clamping torsion spring 209 to provide the paper clamping mechanism 2 with a more refined adjustment capability and higher operational flexibility. The torsion spring limit seat 210 is connected to the first end of the clamping torsion spring 209, and its main function is to provide a stable support point and a limiting function for the clamping torsion spring 209. Through the torsion spring limit seat 210, the elastic force of the clamping torsion spring 209 can act more stably on the clamping rod 203, ensuring that the clamping rod 203 can maintain a stable position and posture during the clamping process. This limiting function can effectively prevent the clamping torsion spring 209 from being excessively twisted or positionally offset during operation, thereby improving the reliability and repeatability of the clamping action.

[0113] The clamping adjustment member 211 is connected to the second end of the clamping torsion spring 209. By rotating the clamping adjustment member 211, the torque of the clamping torsion spring 209 can be adjusted. This design enables the paper clamping mechanism 2 to flexibly adjust the clamping force according to different paper tray specifications and paper feeding requirements. This adjustability not only improves the adaptability and versatility of the paper clamping mechanism 2, but also effectively avoids the problem of paper tray damage or loose clamping caused by excessive or insufficient clamping force.

[0114] Furthermore, not only is a clamping adjustment member 211 provided for the clamping torsion spring 209 to adjust the torque of the clamping torsion spring 209 , but an adjustment member can also be provided to adjust the torque of the contact torsion spring 208 , that is, the torques of both the contact torsion spring 208 and the clamping torsion spring 209 can be adjusted.

[0115] In some cases, the clamping rod 203, the clamping torsion spring 209, the torsion spring limit seat 210, and the clamping adjustment member 211 constitute a paper tape clamping force adjustment mechanism, whose function is to adjust the clamping force on the paper (which has the same meaning as paper tape and paper coil), thereby improving the clamping stability and adapting to different specifications and types of cigarette papers.

[0116] Optionally, a rubber sleeve 214 is sleeved on the end portion of the clamping rod 203 where it cooperates with the paper tray contact rod 201, so that the friction force between the clamping rod 203 and the paper tape is increased by the rubber sleeve 214.

[0118] In some embodiments, the paper tray contact rod 201 is provided with a first side surface 2011, and the first side surface 2011 is provided with a paper clamping groove 2012, and the paper clamping groove 2012 is used to cooperate with the clamping rod 203 to clamp the paper tray.

[0119] In some embodiments, the paper tray contact rod 201 is provided with a second side surface 2013, the second side surface 2013 is used to contact the paper tray, and a contact sharp angle 2014 is formed between the second side surface 2013 and the first side surface 2011, and the contact sharp angle 2014 is used to contact the unsealing tape of the paper tray;

[0120] The paper tray contact rod 201 is provided with a card slot 2015, and the clamping rod 203 is provided with a stop portion 2031; when the stop portion 2031 is inserted into the card slot 2015, the clamping rod 203 is separated from the paper clamping groove 2012; when the contact tip 2014 is pushed by the unsealing tape, the stop portion 2031 withdraws from the card slot 2015, and the clamping rod 203 cooperates with the paper clamping groove 2012.

[0121] In this embodiment, the design of the paper tray contact lever 201 has a unique structure and function to achieve efficient clamping and paper guiding operations on the paper tray. The paper tray contact lever 201 is provided with a first side surface 2011 and a second side surface 2013, wherein the first side surface 2011 is provided with a paper clamping groove 2012, and a contact angle 2014 is formed between the second side surface 2013 and the first side surface 2011. This design enables the paper tray contact lever 201 to perform different functions at different stages.

[0122] After the paper tray contact rod 201 contacts the paper on the paper tray, the paper tray starts to rotate. At this time, the unsealing tape at the end of the paper tray has not yet rotated to the contact point 2014. In this state, since the stopper 2031 is engaged in the slot 2015, the clamping rod 203 and the paper tray contact rod 201 are in a separated state. This separation state is achieved by the cooperation between the stopper 2031 and the slot 2015, ensuring that the clamping rod 203 will not interfere with the paper tray contact rod 201 in the early stage of the paper tray rotation, thereby preparing for the subsequent clamping action.

[0123] As the paper tray continues to rotate, the unsealing tape gradually approaches the contact point 2014. When the unsealing tape contacts the contact point 2014, the unsealing tape applies a thrust to the contact point 2014. This thrust causes the paper tray contact rod 201 to move to a certain extent, thereby causing the stopper 2031 to withdraw from the slot 2015. At this time, the separation of the stopper 2031 from the slot 2015 releases the restriction on the clamping rod 203 and the paper tray contact rod 201.

[0124] After the stopper 2031 exits the slot 2015, the clamping rod 203 and the paper tray contact rod 201 are no longer restricted, and they begin to move toward each other under the elastic force of the contact torsion spring 208 and the clamping torsion spring 209. The elastic force of the contact torsion spring 208 and the clamping torsion spring 209 drives the clamping rod 203 and the paper tray contact rod 201 to approach each other until the clamping portion of the clamping rod 203 is matched with the paper clamping groove 2012 of the paper tray contact rod 201. This matching enables the clamping rod 203 and the paper tray contact rod 201 to tightly clamp the unsealing opening of the paper tray, thereby completing the clamping action.

[0125] After clamping is completed, the robot can perform the subsequent paper guiding action, that is, introduce the paper tape into the equipment.

[0126] The advantage of this design is that the automatic separation and matching of the clamping rod 203 and the paper tray contact rod 201 is achieved through the cooperation between the stopper 2031 and the clamping slot 2015, and the contact between the contact angle 2014 and the unsealing tape. This automated clamping mechanism not only improves the efficiency and reliability of clamping, but also reduces manual intervention and reduces the difficulty of operation. At the same time, the elastic force of the contact torsion spring 208 and the clamping torsion spring 209 ensures the rapidity and stability of the clamping action, so that the entire paper clamping mechanism 2 can operate stably under different working conditions, meeting the high-precision and high-efficiency requirements of the tobacco industry's rolling and splicing equipment for paper guiding operations.

[0127] In some cases, the paper tray contact rod 201, the clamping rod 203, the contact torsion spring 208, the clamping torsion spring 209, and the proximity switch 212 constitute a paper tray unsealing interface detection mechanism, which is used to generate resistance to the paper tray contact rod 201 through the tape at the unsealing opening of the paper tray, triggering the clamping action. The mechanism is sensitive and has a fast action response speed. It can sense the paper tape seal and adjust its sensitivity.

[0128] Please refer to Fig. 9 , Fig. 9 A schematic diagram of an electric cylinder provided in an embodiment of the present application.

[0129] In some embodiments, the paper clamping mechanism 2 further includes:

[0130] The electric cylinder 213 is provided with an electric cylinder push rod 2131, which is used to push the clamping rod 203 so that the clamping rod 203 is separated from the paper clamping groove 2012 and the locking portion 2031 is locked into the locking groove 2015.

[0131] The present application also provides a paper coil and paper guiding system, comprising a robot and the above-mentioned paper coil and paper guiding device, wherein the robot is provided with a mechanical arm, and the mechanical arm is connected to the connecting plate 1 .

[0132] In this embodiment, the paper clamping mechanism 2 further includes an electric cylinder 213, and the electric cylinder 213 is provided with an electric cylinder push rod 2131. The main function of the electric cylinder push rod 2131 is to push the clamping rod 203 to separate it from the paper clamping groove 2012 of the paper tray contact rod 201, and to make the stopper 2031 on the clamping rod 203 snap into the snap groove 2015 of the paper tray contact rod 201. This design provides an active control and reset mechanism for the paper clamping mechanism 2.

[0133] Specifically, when the clamping rod 203 needs to be separated from the paper tray contact rod 201, the electric cylinder push rod 2131 of the electric cylinder 213 extends to push the clamping rod 203 to separate it from the paper clamping groove 2012. At this time, the stopper 2031 on the clamping rod 203 can be smoothly inserted into the clamping groove 2015 of the paper tray contact rod 201, thereby achieving the fixation of the clamping rod 203 and the paper tray contact rod 201.

[0134] In some cases, the electric cylinder 213 is provided with an electric cylinder push rod 2131, an axial fixed support 2132, and a fixed pin 2133. The axial fixed support 2132 is located at the electric cylinder push rod 2131, and the fixed pin 2133 is located at the tail end of the electric cylinder 213, forming a reset mechanism. Its function is to rely on the electric cylinder 213 to extend the electric cylinder push rod 2131 after the paper feeding action is completed, thereby rotating the clamping rod 203 in the clamping force adjustment mechanism, so that the locking portion 2031 at the bottom of the clamping rod 203 enters the slot 2015 of the paper tray contact rod 201, thereby playing a reset role.

[0135] The present application also provides a paper coil and paper guiding system, comprising a robot and the above-mentioned paper coil and paper guiding device, wherein the robot is provided with a mechanical arm, and the mechanical arm is connected to the connecting plate 1 .

[0136] The paper coil and paper guiding system should have all the beneficial technical effects of the above-mentioned paper coil and paper guiding device, which will not be described one by one here.

[0137] In this embodiment, the present application further provides a paper coiling and paper threading system, which includes not only the above-mentioned paper coiling and paper threading device, but also a robot. The robot is connected to the connecting plate 1 of the paper coiling and paper threading device through its mechanical arm. This connection mode enables the robot to accurately control the position and posture of the paper coiling and paper threading device, thereby realizing efficient paper threading operation.

[0138] More importantly, the robot and the electrical components in the paper tray feeding device realize signal connection, which is the core of realizing the automatic operation of the entire system. Specifically, a signal path is established between the robot and electrical components such as sensor 2022, proximity switch 212 and electric cylinder 213. Sensor 2022 can detect in real time whether the paper tray contact rod 201 is in contact with the paper tray, and feed this information back to the robot. Proximity switch 212 is used to detect the position of clamping rod 203 to ensure that the clamping action between clamping rod 203 and paper tray contact rod 201 is accurate, and at the same time it is equivalent to detecting whether the tape at the unsealing port of the paper tray has been triggered. The electric cylinder 213 realizes the reset of clamping rod 203 and paper tray contact rod 201 through the action of its electric cylinder push rod 2131, and this process is also precisely controlled by the robot.

[0139] Through this signal connection, the robot can adjust the action of the robot arm in real time according to the feedback signals from the sensor 2022 and the proximity switch 212, thereby accurately controlling the position and posture of the paper coiling and paper feeding device. At the same time, the robot can also control the action of the electric cylinder 213 to ensure that the reset between the clamping rod 203 and the paper coil contact rod 201 is completed in time. This highly automated control system not only improves the efficiency and accuracy of the paper feeding operation, but also reduces manual intervention, reduces labor intensity, and improves the continuity and stability of production.

[0140] In summary, the paper coiling and paper feeding system provided by the present application realizes a highly automated paper feeding operation through the signal connection between the robot and the electrical components in the paper coiling and paper feeding device. This system not only improves production efficiency, but also enhances the reliability and stability of the entire system, so that it can better meet the high precision and high efficiency requirements of the paper feeding operation of the tobacco industry's rolling and splicing equipment.
