[0025] Embodiment one

[0026] In the related art, when the transparent paper is used up, the transparent paper needs to be positioned and cut for adjustment. Some packaging machines have a roll changing device that affects the positioning of the transparent paper color film, causing the transparent paper cutting position to deviate, resulting in a large number of defective cigarette packs. In addition, if the transparent paper cutting position changes too much, the operator needs to rethread the paper for positioning, reducing the efficiency of the equipment. After the transparent paper is installed, the operator can only manually cut the transparent paper and then use adhesive tape to stick it, ensuring that the transparent paper color film position is normal, so that the cutting position will not deviate, increasing the labor cost of the transparent paper roll change and reducing the roll change efficiency and accuracy, reducing the production efficiency, continuity and stability.

[0027] Figure 1 The structure diagram of the packaging machine transparent paper automatic bonding roll changing control system provided by the present application is shown in the embodiment, which can be applied to the case of automatically bonding and roll changing of the packaging machine transparent paper when the transparent paper is used up.

[0028] Correspondingly, as shown in Figure 1 , the system comprises:

[0029] The cutting control switch 110, the cutter control circuit switch 130, the cutter 140, the heat sealer control circuit switch 120, the heat sealer 150 and the controller 160; the controller 160 is electrically connected with the cutting control switch 110, the controller 160 is electrically connected with the cutter control circuit switch 130, the cutter control circuit switch 130 is electrically connected with the cutter 140, and the cutter 140 is arranged at a preset old paper edge cutting position of a packaging machine; the controller 160 is electrically connected with the heat sealer control circuit switch 120, the heat sealer control circuit switch 120 is electrically connected with the heat sealer 150, and the heat sealer 150 is arranged at a preset new paper and old paper heat sealing position of the packaging machine;

[0030] The cutting control switch 110 is used for generating a roll changing control signal and sending the roll changing control signal to the controller 160 after manually closing the cutting control switch 110.

[0031] The heat sealer control circuit switch 120 is used for controlling the heat sealer 150 to perform a heat sealing operation on the new paper and the old paper at the preset bonding position when a closing control signal of the heat sealer control circuit switch 120 is detected, and resetting the heat sealer 150 when an opening control signal of the heat sealer control circuit switch 120 is detected.

[0032] The cutter control circuit switch 130 is used for controlling the cutter 140 to perform a cutting operation on the preset old paper edge cutting position when a closing control signal of the cutter control circuit switch 130 is detected, and resetting the cutter 140 when an opening control signal of the cutter control circuit switch 130 is detected.

[0033] The controller 160 is used for generating a closing control signal of the heat sealer control circuit switch 120 and sending the closing control signal to the heat sealer control circuit switch 120 when a roll changing control signal is detected, generating a closing control signal of the cutter control circuit switch 130 and sending the closing control signal to the cutter control circuit switch 130 after the closing control signal of the heat sealer control circuit switch 120 is sent to the heat sealer control circuit switch 120 and a first preset delay is passed, generating an opening control signal of the heat sealer control circuit switch 120 and sending the opening control signal to the heat sealer control circuit switch 120 and generating an opening control signal of the cutter control circuit switch 130 and sending the opening control signal to the cutter control circuit switch 130 after the closing control signal of the cutter control circuit switch 130 is sent to the cutter control circuit switch 130 and a second preset delay is passed.

[0034] In the embodiment of the application, the cutting control switch can be specifically understood as a switch for starting a roll changing process, which is manually triggered by an operator and generates a roll changing control signal and sends the roll changing control signal to the controller after being triggered. The cutting control switch can be in the form of a mechanical switch or can be configured in the controller system in the form of a virtual switch (such as a virtual button in a touch screen).

[0035] The cutting knife control circuit switch can be understood as being capable of controlling the working state of the cutting knife according to the received control signal (such as the instruction from the controller). When the cutting control switch 110 is triggered, the controller 160 sends a closing control signal to the cutting knife control circuit switch 130, so that the cutting knife control circuit switch 130 is closed, thereby supplying power to the cutting knife 140, and the cutting knife 140 performs the old paper edge cutting operation at the preset old paper edge cutting position. When the controller 160 sends a disconnection control signal to the cutting knife control circuit switch 130, the cutting knife control circuit switch 130 returns to the untriggered state, and the cutting knife 140 returns to the original state or standby state. The cutting knife can be understood as being a rotating blade or a cutting knife arranged at the preset old paper edge cutting position of the packaging machine. When the cutting knife 140 is powered on, the cutting knife 140 performs the cutting action to cut the old paper edge. When the cutting knife 140 is powered off, the cutting knife 140 returns to the original state or standby state.

[0036] The heat sealer control circuit switch can be understood as being a switch for starting the heat sealing process, which is automatically triggered by the controller and is capable of controlling the working state of the heat sealer according to the received control signal (such as the instruction from the controller). When the controller 160 sends a closing control signal to the heat sealer control circuit switch 120, the heat sealer 150 performs the heat sealing and bonding operation at the preset bonding position. When the controller 160 sends a disconnection control signal to the heat sealer control circuit switch 120, the heat sealer control circuit switch 120 returns to the untriggered state, and the heat sealer 150 returns to the original state or standby state. The heat sealer can be understood as being an electric heating element arranged at the preset heat sealing and bonding position of the packaging machine. When the heat sealer 150 is powered on, the heat sealer 150 can bond the transparent paper of the new and old paper reels together through high temperature. When the heat sealer 150 is powered off, the heat sealer 150 returns to the original state or standby state.

[0037] The controller can be understood as being responsible for coordinating and controlling the operation of the entire device, capable of receiving signals from various sensors and switches, and controlling various components according to the preset logic or program, such as a programmable logic controller (PLC) or an industrial computer. The electrical connection refers to the electrical connection between devices through wires, interfaces, connectors or interfaces.

[0038] The first preset delay can be understood as a preset time required for the cutter to perform the cutting operation after the heat sealer is started. The transparent paper on the new paper tray is connected to the transparent paper on the old paper tray by heat sealing and bonding, ensuring that the packaging process can continue after the paper tray is replaced. Because different devices have different response times, the first preset delay needs to be set according to the mechanical characteristics and control system of the device. For example, the heat sealer needs a certain time to reach the working temperature, and in order to achieve the desired effect of heat sealing and bonding of the transparent paper on the new and old paper trays, the first preset delay needs to be at least greater than the sum of the time for the heat sealer to heat up to the working temperature and the time required for the transparent paper on the new and old paper trays to achieve the desired effect of heat sealing and bonding.

[0039] The second preset delay can be understood as a preset time required for the cutter and the heat sealer to perform the return operation after the cutter performs the cutting operation. After the new and old paper are bonded, the excess transparent paper on the old paper tray is cut off to ensure that the transparent paper on the new paper tray can smoothly enter the conveying system of the packaging machine, avoiding problems in the packaging process caused by interference of the old paper edge. The second preset delay needs to be at least greater than the time required for the cutter to complete the cutting operation to ensure the cutting quality and avoid incomplete cutting or material damage caused by premature return.

[0040] Specifically, when the transparent paper on the old paper tray is about to run out and needs to be replaced, the operator manually stops the packaging machine device and adjusts the transparent paper on the old paper tray to the specified position of the old paper by manually rotating the device, ensuring that the positioning mark (usually a specific pattern or mark printed on the transparent paper) on the transparent paper on the old paper tray is aligned to the specified position of the device, so that after the paper tray is replaced, the transparent paper on the new and old paper trays can be smoothly connected, and the patterns or marks of the new and old transparent paper films can be accurately aligned. The human manually closes the cutting control switch 110 and sends a roll replacement control signal to the controller 160. When the controller 160 receives the roll replacement control signal, it sends a closing control signal to the heat sealer control circuit switch 120. When the heat sealer control circuit switch 120 receives the closing control signal, it controls the heat sealer 150 to perform the heat sealing and bonding operation on the new paper and the old paper at the preset bonding position. After the controller 160 sends the closing control signal to the heat sealer control circuit switch 120, it sends a closing control signal to the cutter control circuit switch 130 after a first preset delay. When the cutter control circuit switch 130 receives the closing control signal, it controls the cutter 140 to perform the old paper edge cutting operation on the preset old paper edge cutting position.

[0041] After the controller 160 sends the closing control signal to the cutter control circuit switch 130, after a second preset delay, the controller 160 sends the opening control signal to the heat sealer control circuit switch 120 and the opening control signal to the cutter control circuit switch 130. When the heat sealer control circuit switch 120 receives the opening control signal, the heat sealer control circuit switch 120 returns to the non-triggered state, and the heat sealer 150 is reset. When the cutter control circuit switch 130 receives the opening control signal, the cutter control circuit switch 130 returns to the non-triggered state, and the cutter 140 is reset. The cutting control switch 110 can be manually adjusted to the non-triggered state after the cutter and the heat sealer are reset after the roll change is completed, to ensure that each component of the equipment returns to the initial state or the preparation state after each operation, thereby realizing the roll change operation in the continuous production process and avoiding faults and production interruptions caused by incorrect component positions. In addition, a safety delay can be set to ensure that the roll change operation is not repeatedly triggered within the safety delay time range after the roll change operation is completed, so that the operator can manually adjust the cutting control switch 110 to return to the non-triggered state.

[0042] The packaging machine transparent paper automatic bonding roll change control system of the embodiment of the application comprises: a cutting control switch for sending a roll change signal after the cutting control switch is closed; a heat sealer control circuit switch for controlling heat sealing bonding or resetting of a heat sealer when a closing or opening signal of the heat sealer control circuit switch is detected; a cutter control circuit switch for controlling cutting of old paper edges or resetting of a cutter when a closing or opening signal of the cutter control circuit switch is detected; and a controller for sending a closing signal of the heat sealer control circuit switch when the roll change signal is detected, sending a closing signal of the cutter control circuit switch after a first delay, and sending an opening signal of the heat sealer control circuit switch and an opening signal of the cutter control circuit switch after a second delay. Only manual operation of the corresponding switches is required to realize automation of heat sealing bonding and cutting of old paper edges through the controller, thereby reducing labor costs, improving roll change efficiency and accuracy, and improving production efficiency, continuity and stability.

[0043] Optionally, in the above embodiments, the cutter control circuit switch is a cutter control relay, a power supply end of the cutter control relay is electrically connected with the controller, and a normally open contact of the cutter control relay is electrically connected with a power supply end of the cutter electromagnetic valve.

[0044] The controller is specifically configured to, after sending the closing control signal of the heat sealer control circuit switch to the heat sealer control circuit switch, send a high-level signal to the cutter control relay after a first preset delay, so that the cutter control relay is triggered to make the cutter electromagnetic valve powered on after being turned on.

[0045] After sending the high-level signal to the cutter control relay, a second preset delay is performed, and a low-level signal is sent to the cutter control relay to trigger the cutter control relay to make the cutter solenoid de-energized after being turned off.

[0046] Specifically, the controller provides power to the cutter control relay through electrical connection to ensure that the relay can work normally. After sending a closing control signal to the heat sealer control circuit switch, the controller performs a first preset delay, sends a high-level signal to the cutter control relay to trigger the normally open contact of the cutter control relay to close, and the cutter solenoid is energized, thereby starting the cutter to perform the cutting operation. After sending the high-level signal to the cutter control relay, a second preset delay is performed, and a low-level signal is sent to the cutter control relay to trigger the normally open contact of the cutter control relay to open, and the cutter solenoid is de-energized, thereby stopping the cutting operation of the cutter and returning the cutter to the original position. At the same time, the cutter control relay also returns to the untriggered state. Through the relay, the electrical isolation function is realized, ensuring the safe isolation of the control circuit (including the power supply end of the cutter control relay and the controller) and the main circuit (including the normally open contact of the cutter control relay and the cutter solenoid), avoiding electrical faults. Through the precise delay control of the controller, the automatic operation of the cutter and the heat sealer is realized, ensuring that each component of the equipment returns to the initial state or the preparation state after each operation, thereby realizing the roll change operation in the continuous production process, avoiding faults and production interruptions caused by incorrect component positions, ensuring the sequence, accuracy and stability of the heat sealing and cutting operations, avoiding equipment failures caused by too fast operation, incomplete bonding of new and old paper, insufficient cutting of transparent paper, and poor product quality and material damage caused thereby, reducing manual intervention and equipment downtime, improving overall production efficiency, and improving adaptability in large-scale continuous production scenarios.

[0047] Optionally, based on the above embodiments, the heat sealer control circuit switch is a heat sealer control relay, and the power supply end of the heat sealer control relay is electrically connected to the controller; the normally open contact of the heat sealer control relay is electrically connected to the power supply end of the heat sealer solenoid;

[0048] The controller is specifically configured to, when detecting a roll change control signal, send a high-level signal to the heat sealer control relay to trigger the heat sealer control relay to energize the heat sealer solenoid after being turned on; and

[0049] After sending the high-level signal to the cutter control relay, a second preset delay is performed, and a low-level signal is sent to the cutter control relay to trigger the cutter control relay to make the cutter solenoid de-energized after being turned off.

[0050] Specifically, the controller provides power to the heat sealer control relay through the electrical connection to ensure that the relay can work normally. When the controller detects the roll change control signal, it sends a high-level signal to the heat sealer control relay to trigger the normally open contact of the heat sealer control relay to close, and the heat sealer solenoid is powered on, thereby starting the heat sealer to perform the new paper and old paper heat sealing and bonding operation. After the controller sends a high-level signal to the cutter control relay, it sends a low-level signal to the heat sealer control relay after a second preset delay to trigger the normally open contact of the heat sealer control relay to open, and the heat sealer solenoid is powered off, thereby stopping the heat sealing and bonding operation of the heat sealer, and the heat sealer returns to the original position, and the heat sealer control relay also returns to the untriggered state. The relay realizes electrical isolation function, ensuring the safe isolation of the control circuit (including the power supply end of the heat sealer control relay and the controller) and the main circuit (including the normally open contact of the heat sealer control relay and the heat sealer solenoid), avoiding electrical faults. Through the precise delay control of the controller, the automatic operation of the cutter and the heat sealer is realized, ensuring that each component of the equipment returns to the initial state or the preparation state after each operation, thereby realizing the roll change operation in the continuous production process, avoiding faults and production interruptions caused by incorrect component positions, ensuring the sequence, accuracy and stability of the heat sealing and cutting operations, avoiding equipment failures, incomplete bonding of new and old paper, insufficient cutting of transparent paper and other problems caused by poor product quality and material damage, reducing manual intervention and equipment downtime, improving overall production efficiency and adaptability in large-scale continuous production scenarios.

[0051] Further, on the basis of the above-mentioned embodiments, the system further comprises a paper disc tensioning switch, a paper disc tensioning circuit switch, a paper disc tensioning device, and a paper disc in-place detection device; the controller is electrically connected with the paper disc tensioning switch, the controller is electrically connected with the paper disc tensioning circuit switch, the paper disc tensioning circuit switch is electrically connected with the paper disc tensioning device, the paper disc tensioning device is arranged around the paper disc mounting position of the packaging machine, the paper disc in-place detection device is arranged at the preset paper disc mounting position of the packaging machine, and the controller is electrically connected with the paper disc in-place detection device.

[0052] The paper disc tensioning switch is used to generate a new paper disc installation control signal and send it to the controller after manually closing the paper disc tensioning switch.

[0053] The paper disc tensioning circuit switch is used to control the paper disc tensioning device to open to loosen the paper disc when a closing control signal for the paper disc tensioning circuit switch is detected, and control the paper disc tensioning device to close to tension the paper disc when a disconnecting control signal for the paper disc tensioning circuit switch is detected.

[0054] The paper disc in-place detection device is used to generate a tensioning new paper disc control signal and send it to the controller after detecting that the new paper disc is installed at the preset position.

[0055] The controller is configured to generate a closing control signal for the paper roll tensioning circuit switch and send the closing control signal to the paper roll tensioning circuit switch when a new paper roll installation control signal is detected, and generate an opening control signal for the paper roll tensioning circuit switch and send the opening control signal to the paper roll tensioning circuit switch after a third preset delay when a new paper roll tensioning control signal is detected.

[0056] In the embodiment of the present application, the third preset delay can be understood as a preset time required for triggering the paper roll tensioning device to tension the paper roll after the new paper roll is detected to be installed at the preset position. In order to ensure the safety of the operation and the reliability of the equipment, the third preset delay should be long enough to ensure that the paper roll is installed in place and the operator has finished the installation operation, so as to avoid equipment failure caused by too fast operation, safety problems or material damage caused by the operator not exiting the installation operation in time.

[0057] Specifically, when a new paper roll needs to be installed during the operation of the packaging machine, the paper roll tensioning switch sends a new paper roll installation control signal to the controller after the paper roll tensioning switch is manually closed by the operator. After receiving the new paper roll installation control signal, the controller sends a closing control signal to the paper roll tensioning circuit switch. After receiving the closing control signal, the paper roll tensioning circuit switch controls the paper roll tensioning device to open to loosen the paper roll for the operator to install a new paper roll. After the operator installs the new paper roll in place, the paper roll in place detection device (which can be a paper roll in place detection device installed at the rear end of the paper roll holder) detects that the new paper roll is installed in the preset position and sends a new paper roll tensioning control signal to the controller. After receiving the new paper roll tensioning control signal, the controller sends a disconnection control signal to the paper roll tensioning circuit switch after a third preset delay. After receiving the disconnection control signal, the paper roll tensioning circuit switch controls the paper roll tensioning device to close to tension the paper roll. After the paper roll is tensioned, the operator positions the color film transparent paper positioning mark (usually a specific pattern or mark printed on the transparent paper) to the new paper roll position by using the manual winding device, so that the transparent papers of the new and old paper rolls can be smoothly docked and the patterns or marks of the color films of the new and old transparent papers can be accurately aligned during subsequent paper roll replacement. In addition, after the paper roll is tensioned, the operator can manually adjust the paper roll tensioning switch to the untriggered state to ensure that each component of the device returns to the initial state or the preparation state after each new paper roll installation operation, thereby realizing the new paper roll replacement operation in the continuous production process and avoiding faults and production interruptions caused by incorrect component positions. In addition, a safety delay can be set to ensure that the new paper roll installation operation is not repeatedly triggered within the safety delay time range after the installation of the new paper roll is completed, ensuring that the operator can manually adjust the paper roll tensioning switch to the untriggered state. Through the precise delay control of the controller, the automatic operation of the paper roll tensioning device is realized, reducing manual intervention, improving production efficiency and stability, and adaptability in large-scale continuous production scenarios, ensuring the sequence, accuracy of the paper roll tensioning operation and the safety of the operator, and improving the packaging quality.

[0058] Optionally, in the above embodiments, the paper roll tensioning circuit switch is a paper roll tensioning control relay, the power supply end of the paper roll tensioning control relay is electrically connected with the controller, and the normally open contact of the paper roll tensioning control relay is electrically connected with the power supply end of the paper roll tensioning electromagnetic valve.

[0059] The controller is specifically configured to send a high-level signal to the paper roll tensioning control relay to trigger the paper roll tensioning control relay to make the paper roll tensioning electromagnetic valve powered on after being turned on when a new paper roll installation control signal is detected, and send a low-level signal to the paper roll tensioning control relay to trigger the paper roll tensioning control relay to make the paper roll tensioning electromagnetic valve lose power after being turned off after a third preset delay when a new paper roll tensioning control signal is detected.

[0060] Specifically, the controller provides power supply to the paper tray tensioning control relay through the electrical connection to ensure that the relay can work normally. When the controller detects the new paper tray installation control signal, it sends a high-level signal to the paper tray tensioning control relay to trigger the normally open contact of the paper tray tensioning control relay to close, and the paper tray tensioning solenoid is powered on, so that the paper tray tensioning device is opened to loosen the paper tray. After the new paper tray is installed in place, the controller detects the tensioning new paper tray control signal, and after a third preset delay, sends a low-level signal to the paper tray tensioning control relay to trigger the normally open contact of the paper tray tensioning control relay to open, and the paper tray tensioning solenoid is powered off, so that the paper tray tensioning device is closed to tension the paper tray, while the paper tray tensioning control relay also returns to the untriggered state. The relay realizes the electrical isolation function, ensuring the safe isolation of the control circuit (including the power supply end of the paper tray tensioning control relay and the controller, etc.) and the main circuit (including the normally open contact of the paper tray tensioning control relay and the paper tray tensioning solenoid, etc.), avoiding electrical faults. Through the precise delay control of the controller, the automatic operation of the paper tray tensioning device is realized, reducing manual intervention, improving production efficiency and stability, and adaptability in large-scale continuous production scenarios, ensuring the sequence, accuracy of paper tray tensioning operation and the safety of the operator, and improving the packaging quality.

[0061] Optionally, based on the above embodiments, the paper tray in-place detection device is an optical detection device, which includes a transmitting end device and a receiving end device.

[0062] The transmitting end device and the receiving end device are respectively arranged at the two ends of the paper tray rack at the preset installation position of the paper tray, for real-time detection of the installation result of the new paper tray by optical detection, and generating a tensioning new paper tray control signal and sending it to the controller after detecting that the new paper tray is installed in the preset position.

[0063] In the embodiments of the present application, the photoelectric detection device can be specifically understood as a device for detecting the position or state of an object by utilizing the characteristics of light and photoelectric effect, such as a photoelectric sensor. The transmitting end device is usually installed on one side of the paper tray frame, facing the installation position of the paper tray. The transmitting end device is responsible for transmitting a light beam (such as infrared light or visible light, etc.), and detecting whether the paper tray is in place. The receiving end device is installed on the other side of the paper tray frame, opposite the transmitting end device, for receiving the light beam emitted by the transmitting end. When the paper tray is correctly installed, the light beam is blocked, and the receiving end device cannot detect the light beam, thereby confirming that the paper tray is in place. After detecting that a new paper tray is installed at the preset position, the paper tray in-place detection device generates a new paper tray tensioning control signal and sends it to the controller. After receiving the signal, the controller triggers the paper tray tensioning device to tension the paper tray. Through the photoelectric detection device, the automatic detection of the paper tray installation is realized, the manual intervention and the equipment downtime are reduced, the overall production efficiency is improved, and the adaptability in the scene of large-scale continuous production is improved. Through real-time detection, the accuracy of the paper tray installation is ensured, the equipment failure caused by the paper tray not being in place is avoided, and the running stability of the equipment and the packaging quality of the product are improved.

[0064] Optionally, on the basis of each of the above embodiments, the cutting control switch is a three-gear knob switch, the three-gear knob switch is arranged on the machine body of the packaging machine, and the three-gear knob switch comprises: a left side normally open contact and a right side normally open contact, the left side normally open contact and the right side normally open contact are electrically connected with input pins of the controller respectively, and are used for generating a left side roll changing control signal or a right side roll changing control signal and sending the signal to the controller after the left side normally open contact or the right side normally open contact is manually closed.

[0065] The cutter control circuit switch comprises a left side cutter control circuit switch and a right side cutter control circuit switch, one end of the left side and right side cutter control circuit switches is connected with output pins of the controller respectively, and the other end of the left side and right side cutter control circuit switches is electrically connected with the left side cutter and the right side cutter respectively, the left side cutter control circuit switch is used for controlling the left side cutter to cut the old paper edge at the preset old paper edge cutting position when a closing control signal of the left side cutter control circuit switch is detected, and the left side cutter is returned to the original position when a disconnecting control signal of the cutter control circuit switch is detected, and the right side cutter control circuit switch is used for controlling the right side cutter to cut the old paper edge at the preset old paper edge cutting position when a closing control signal of the right side cutter control circuit switch is detected, and the right side cutter is returned to the original position when a disconnecting control signal of the cutter control circuit switch is detected.

[0066] The cutter comprises a left side cutter and a right side cutter, the left side cutter is arranged at the preset old paper edge cutting position of the left side paper tray of the packaging machine, and the right side cutter is arranged at the preset old paper edge cutting position of the right side paper tray of the packaging machine.

[0067] The controller is configured to, when detecting the left or right roll changing control signal, send a closing control signal to the heat sealer control circuit switch; after sending the closing control signal to the heat sealer control circuit switch, wait for a first preset time delay, and then send a closing control signal to the left or right cutter control circuit switch; after sending the closing control signal to the left or right cutter control circuit switch, wait for a second preset time delay, and then send an opening control signal to the left or right cutter control circuit switch.

[0068] Specifically, the operator turns the three-position rotary switch to the left or right, closes the left or right normally open contact, and sends a left or right roll changing control signal to the controller. The controller detects the left or right roll changing control signal and sends a closing control signal to the heat sealer control circuit switch. The heat sealer control circuit switch receives the closing control signal and controls the heat sealer to perform heat sealing and bonding of the new paper and the old paper at the preset bonding position. After the controller sends the closing control signal to the heat sealer control circuit switch, it waits for a first preset time delay and then sends a closing control signal to the left or right cutter control circuit switch. The left or right cutter control circuit switch detects the closing control signal and controls the left or right cutter to cut the old paper edge at the preset cutting position. After the controller sends the closing control signal to the left or right cutter control circuit switch, it waits for a second preset time delay and then sends an opening control signal to the left or right cutter control circuit switch. The left or right cutter control circuit switch detects the opening control signal and returns the left or right cutter to the original position, and the left or right cutter control circuit switch also returns to the untriggered state. After completing the left or right roll changing operation, the operator can manually adjust the three-position rotary switch to the untriggered state to ensure that each component of the device returns to the initial state or the standby state after each operation, thereby achieving roll changing operation in continuous production process and avoiding faults and production interruptions caused by incorrect component positions. In addition, a safety time delay can be set to ensure that the left or right roll changing operation is not repeated within the safety time delay after the left or right roll changing operation is completed, and the operator can manually adjust the three-position rotary switch to the untriggered state.

[0069] By setting the three-gear knob switch on the body of the packaging machine, the operator can control the roll changing operation by left and right dialing of the knob, which is intuitive and easy to operate, and the operator can quickly start or stop the roll changing operation. The design of separate control of left and right makes the operator can control the roll changing operation of the left or right side separately, avoiding the problems of equipment failure, operator injury or material waste caused by misoperation. Through the precise delay control of the controller, the automatic operation of the cutter and the heat sealer is realized, ensuring the sequence, accuracy and stability of the heat sealing and cutting operation, avoiding the problems of equipment failure, incomplete bonding of new and old paper, insufficient cutting of transparent paper and poor product quality caused by too fast operation, reducing the manual intervention and equipment downtime, improving the overall production efficiency and the adaptability in the scene of large-scale continuous production.

[0071] The paper disc tensioning circuit switch includes a left paper disc tensioning circuit switch and a right paper disc tensioning circuit switch, one end of the left and right paper disc tensioning circuit switches is connected to an output pin of the controller, and the other end of the left and right paper disc tensioning circuit switches is connected to the left and right paper disc tensioning devices, respectively, for controlling the left or right paper disc tensioning device to open to loosen the paper disc when a closing control signal to the left or right paper disc tensioning circuit switch is detected, and controlling the left or right paper disc tensioning device to close to tension the paper disc when a disconnecting control signal to the left or right paper disc tensioning circuit switch is detected;

[0072] The paper disc tensioning device includes a left paper disc tensioning device and a right paper disc tensioning device, which are arranged around the left paper disc installation place and the right paper disc installation place of the packaging machine, respectively;

[0073] The paper disc in-place detection device includes a left paper disc in-place detection device and a right paper disc in-place detection device, which are arranged at the preset installation positions of the left and right paper discs of the packaging machine, respectively, for generating a tensioning left or right new paper disc control signal and sending it to the controller when detecting that the left or right new paper disc is installed at the preset position;

[0074] The controller is configured to generate a closing control signal for the left or right paper tray tensioning circuit switch and send the closing control signal to the left or right paper tray tensioning circuit switch when a left or right new paper tray installation control signal is detected; and generate an opening control signal for the left or right paper tray tensioning circuit switch and send the opening control signal to the left or right paper tray tensioning circuit switch after a third preset delay when a left or right new paper tray tensioning control signal is detected.

[0075] Specifically, an operator manually closes the left or right paper tray tensioning control button to trigger a left or right new paper tray installation operation, generates a left or right new paper tray installation control signal and sends the left or right new paper tray installation control signal to the controller. When the controller detects the left or right new paper tray installation control signal, the controller sends a closing control signal to the left or right paper tray tensioning circuit switch. The left or right paper tray tensioning circuit switch detects the closing control signal and controls the left or right paper tray tensioning device to open, thereby loosening the paper tray for the operator to install a left or right new paper tray. The left or right paper tray in-place detection device detects that the left or right new paper tray is installed at a preset position, generates a left or right new paper tray tensioning control signal and sends the left or right new paper tray tensioning control signal to the controller. The controller detects the left or right new paper tray tensioning control signal, sends an opening control signal to the left or right paper tray tensioning circuit switch after a third preset delay. The left or right paper tray tensioning circuit switch detects the opening control signal and controls the left or right paper tray tensioning device to close, thereby tensioning the paper tray. The left or right paper tray tensioning circuit switch also returns to an untriggered state. In addition, after tensioning the paper tray, the operator can manually adjust the left or right paper tray tensioning control button to the untriggered state, so that each component of the device returns to the initial state or the standby state after each left or right new paper tray installation operation, thereby realizing the left or right new paper tray installation operation in a continuous production process and avoiding malfunctions and production interruptions caused by incorrect component positions. In addition, a safety delay can be set to ensure that the left or right new paper tray installation operation is not repeatedly triggered within a safety delay time range after the left or right new paper tray installation operation is completed, so that the operator can manually adjust the left or right paper tray tensioning control button to return to the untriggered state.

[0076] By setting the control button on the body of the packaging machine, the operator can control the paper disc tensioning device through intuitive button operation, which is simple and convenient to operate, and can quickly start or stop the installation of a new paper disc operation. The design of left and right separate control allows the operator to control the installation of a new paper disc operation on the left or right side separately, avoiding equipment failure, safety accidents or material waste caused by misoperation. The installation of a new paper disc operation on both sides can also be performed simultaneously, reducing equipment downtime and improving production efficiency. Through precise delay control of the controller, automatic operation of the paper disc tensioning device is realized, reducing manual intervention, improving production efficiency and stability, and adaptability in large-scale continuous production scenarios, ensuring the sequence, accuracy of the paper disc tensioning operation and the safety of the operator, and improving the packaging quality.

This embodiment can be applied to the case of automatically bonding roll changing of the packaging machine transparent paper when the transparent paper is used up. The method can be executed by the controller configured in the packaging machine transparent paper automatic bonding roll changing control system.

[0084] Correspondingly, as shown in Figure 2 , the method comprises:

[0085] S210, when the roll changing control signal is detected, a closing control signal for the heat sealer control circuit switch is generated and sent to the heat sealer control circuit switch.

In addition, a safety delay can also be set to ensure that the roll change operation is not repeatedly triggered within the safety delay time range after the roll change operation is completed, ensuring that the operator can manually adjust the cutting control switch to the untriggered state.

Only the corresponding switch needs to be manually operated, and the paper disc in-place detection, new paper disc tensioning, heat sealing and automatic cutting of the old paper edge are realized by the controller, which reduces the labor cost, improves the roll change efficiency and accuracy, and improves the production efficiency, continuity and stability.

[0096] Specific application scenarios

[0097] In order to facilitate understanding, the specific application scenarios suitable for each embodiment of the present application will be described. The original part of the packaging machine originally has a transparent paper automatic roll changing device, which will be heat sealed and bonded when the transparent paper is used up. However, during the roll changing process after the transparent paper roll is used up, the transparent paper needs to be positioned and cut for adjustment operation, and if the roll changing function of the packaging machine is continued to be used, it will affect the positioning of the transparent paper film, causing the cutting position of the film to deviate, resulting in a large number of defective cigarette packs, and the change in the cutting position of the film is too large, so the operator needs to rethread the paper to position it, reducing the efficiency of the equipment. After the transparent paper is installed in the positioning position, the operator can only manually cut the transparent paper, and then use adhesive tape to bond it, to ensure that the cutting position will not deviate. The automatic roll changing of the transparent paper cannot be realized, and the new transparent paper roll cannot be preset during the operation of the equipment. When the roll is changed, the machine needs to be stopped, the old paper is cut, the old paper roll is removed, the new paper roll is replaced, the adhesive tape is used to bond it to the correct position, and the adhesive tape may also cause the transparent paper to be blocked if it is too thick, increasing the labor cost of roll changing and reducing the efficiency of the equipment.

[0098] In order to solve the above problems, the present application provides a packaging machine transparent paper automatic bonding roll changing control system, taking a C600 film transparent paper packaging machine as an example, Figure 3It is a kind of packaging machine transparent paper automatic bonding roll change control system electrical schematic diagram suitable for the embodiment of the application, the system includes: siemens S7-200PLC, left paper disc in place detection device B1, right paper disc in place detection device B2, left cutting knob S1, right cutting knob S2, left paper disc tensioning button S3, right paper disc tensioning button S4, left cutter solenoid valve control relay K1, right cutter solenoid valve control relay K2, heat sealer solenoid valve control relay K3, left paper disc tensioning solenoid valve control relay K4 and right paper disc tensioning solenoid valve control relay K5 and other parts constitute, can automatically heat seal transparent paper on left and right paper disc and carry out bonding roll change.

[0099] In a specific example, a Siemens PLC is installed in the C600 transparent paper packaging machine cabinet, the PLC is powered by a 24V positive and negative power supply line, a 3-grade rotary knob switch is added to the C600 transparent paper packaging machine touch screen button panel, the rotary knob is installed with two normally open contacts, one end of the two normally open contacts is linked to the 24V positive power supply line, and the other end of the two normally open contacts is connected to the PLC input points I0.0 and I0.1 respectively. The left paper disc tensioning control button and the right paper disc tensioning control button are installed on the body of the small transparent packaging machine, each button has a normally open contact, one end of the contact is connected to the 24V positive power supply line, and the other end is connected to the PLC input points I0.4 and I0.5 respectively. The input points I0.3 and I0.2 of the PLC are connected to the output signals of the in-place sensors B1 and B2 installed at the rear end of the paper disc holder respectively. Relays K1, K2, K3, K4 and K5 are installed in the packaging machine cabinet. One end of the relay K1 is connected to the PLC output point Q0.0, the other end of the relay K1 is connected to the 24V negative power supply line, the common end of the normally open contact of the relay K1 is connected to the 24V positive power supply line, and the other end is connected to the left cutter solenoid valve coil No. 1 pin to control the left cutter work.

One end of the relay K3 is connected to the PLC output point Q0.2, the other end of the relay K3 is connected to the 24V negative power supply line, the common end of the normally open contact of the relay K3 is connected to the 24V positive power supply line, and the other end is connected to the heat sealer solenoid valve coil No. 1 pin to control the heat sealer work. One end of the relay K4 is connected to the PLC output point Q0.3, the other end of the relay K4 is connected to the 24V negative power supply line, the common end of the normally open contact of the relay K4 is connected to the 24V positive power supply line, and the other end is connected to the left paper disc tensioning solenoid valve coil No. 1 pin to control the left paper disc tensioning device work. One end of the relay K5 is connected to the PLC output point Q0.4, the other end of the relay K5 is connected to the 24V negative power supply line, the common end of the normally open contact of the relay K5 is connected to the 24V positive power supply line, and the other end is connected to the right paper disc tensioning solenoid valve coil No. 1 pin to control the right paper disc tensioning device work.

[0100] When the device is running, the left or right paper tray tension button S3 or S4 is pressed manually, the PLC input point I0.4 or I0.5 receives a 24V high level signal, the PLC output point Q0.3 or Q0.4 outputs a 24V high level to turn on the relay K4 or K5, the K4 or K5 normally open contact is closed, the left or right paper tray tension solenoid valve installed on the device body is energized to work, the solenoid valve works to open the paper tray tension mechanism, and the artificial installs a new paper tray. When the paper tray is installed in place, the left or right paper tray in place detection device B1 or B2 detects the paper tray, the PLC input point I0.3 or I0.2 receives a 24V high level signal, and the internal program timer passes through the preset tension delay. The PLC automatically disconnects the relay, the solenoid valve loses power, the paper tray tension mechanism closes to tension the new paper tray, and the color film transparent paper positioning mark is preset to the new paper specified position.

[0101] When the old paper tray is almost exhausted, the device is manually stopped, the old paper color film transparent paper positioning mark is preset to the old paper specified position, and the left or right cutting knob switch S1 or S2 is manually rotated.

The internal program timer passes through the preset return delay, the PLC automatically disconnects the relay, the cutter and the heat sealer return, and the device is run again. At this time, the new and old transparent papers are bonded to the correct position, ensuring normal operation of the device.

[0102] The packaging machine transparent paper automatic bonding roll change control system provided by the embodiment of the application realizes automatic control through a PLC, can automatically detect the positioning of a paper disc, automatically tension a new paper disc, automatically heat seal and bond, and automatically cut off the old paper edge. Manual intervention is reduced, and production efficiency is improved. An operator only needs to press a corresponding button or knob switch to complete the replacement and bonding process of the paper disc. The delay control of the PLC internal program ensures the sequential execution of each step, reducing the possibility of operation errors. The system ensures the accurate bonding position of the new and old transparent paper through the positioning mark preset function, avoids packaging quality problems caused by position deviation, and improves the consistency and aesthetics of the product. The delay function of the PLC control and the precise action of the relay ensure the coordinated action of the cutter and the heat sealer, avoid equipment failure or material damage caused by asynchronous action, and improve the running stability of the equipment. Since most of the roll change and bonding process is automatically completed by the equipment, the dependence on the operator is reduced, the labor cost is reduced, and the errors and risks caused by manual operation are also reduced. The automated roll change and bonding process shortens the roll change time, reduces the equipment downtime, improves the overall production efficiency, and is especially suitable for large-scale continuous production scenarios.
