[0002] Currently, the splicing of the ZJ17 cigarette making machine roll paper is done by two high-speed pulse sensors that generate pulses and count the pulses to control the roll changing and splicing of the roll paper.

[0049] See also Figure 1 , Figure 1 The figure shows an overall flow chart of a method for controlling the remaining amount of a paper roll tail frame of a winder provided by an embodiment of the present application.

[0050] like Figure 1 As shown, the method for controlling the remaining amount of the tail frame of the paper roll for the winder can at least include the following steps:

[0051] Step 102: When it is detected that the remaining amount of the roll paper in the tail frame of the paper tray is in a preset remaining range, a high-level signal is output to the first relay based on the second output end of the controller, so that the normally open contact of the first relay is converted from the disconnected state to the conductive state, the normally closed contact of the first relay is converted from the conductive state to the disconnected state, and the normally open contact of the second relay is converted from the conductive state to the disconnected state.

[0052] In an embodiment of the present application, the method for controlling the remaining amount of the tail frame of the tobacco roll of a tobacco rolling machine can be applied to, but is not limited to, a remaining amount control system. The remaining amount control system can include at least a controller, a first relay, and a second relay. The controller can be a Siemens PLC controller. The first relay can correspond to a normally open contact and a normally closed contact. The second relay can correspond to a normally open contact. The first input end of the controller can be connected to the clock pulse signal output end of the tobacco rolling machine to obtain the RCP tobacco rod clock pulse signal output by the tobacco rolling machine when the tobacco rolling machine is operating normally, and can count the output clock pulse signal. The second input end of the controller can be connected to the paper tray acceleration signal output end of the tobacco rolling machine to receive an enable signal corresponding to the paper tray acceleration output by the tobacco rolling machine. The enable signal can be a signal allowing the operation of the paper tray acceleration device of the tobacco rolling machine. That is, when the enable signal is received, it indicates that the paper tray acceleration device of the tobacco rolling machine can operate normally at this time, so as to facilitate the splicing of the tobacco rolls. Here, the paper tray acceleration device of the winder can be understood as controlling the splicing of the paper roll by controlling the rotation speed of the paper tray tail frame. Its specific structure is conventional in the art and will not be described in detail here. The first output terminal of the controller can form a circuit with the second relay and the ground terminal, and a normally closed contact of the first relay is provided between the first output terminal and the second relay to control the conduction or disconnection of the circuit by the normally closed contact of the first relay. Here, the normally closed contact of the first relay can be understood as switching from a conducting state to an off state (i.e., controlling the circuit of the second relay to be disconnected) when the first relay receives a high-level signal, and switching from an off state to a conducting state (i.e., controlling the circuit of the second relay to be open) when the first relay receives a low-level signal (or does not receive a level signal). The second output terminal of the controller can form a circuit with the first relay and the ground terminal, so that when a high-level signal is output to the first relay, the normally closed contact of the first relay can be switched from a conducting state to an off state, and the normally open contact of the first relay can be switched from an off state to a conducting state.

[0053] A normally closed contact of the first relay is disposed between the second relay and the paper tray acceleration signal output terminal of the winder. When the normally closed contact of the first relay is in an on state, the second relay can receive a high-level signal outputted from the paper tray acceleration signal output terminal of the winder (the second relay, the paper tray acceleration signal output terminal of the winder, and the ground point form a circuit). When the normally closed contact of the first relay is in an off state, the second relay can be connected to the circuit containing the first output terminal of the controller to receive the level signal outputted by the first output terminal of the controller. A normally open contact of the second relay is disposed between the paper tray acceleration signal output terminal of the winder and the paper tray acceleration device. When the second relay receives a high-level signal, the normally open contact of the second relay switches from an off state to a on state, thereby enabling the paper tray acceleration device to receive the paper tray acceleration signal and perform paper roll splicing. When the second relay receives a low-level signal (or does not receive a level signal), the normally open contact of the second relay switches from an on state to an off state, thereby deactivating the paper tray acceleration device.

[0054] Specifically, when controlling the remaining amount of paper roll of the winder, when it is detected that the remaining amount of paper roll of the tail frame of the paper tray is within a preset remaining amount range, it indicates that the splicing speed of the paper roll needs to be controlled at this time, and then a high-level signal can be output to the first relay based on the second output terminal of the controller, so that the normally open contact of the first relay is converted from an open state to a conductive state, and the normally closed contact of the first relay is converted from a conductive state to an open state. Since the normally closed contact of the first relay is provided between the second relay and the paper tray acceleration signal output terminal of the winder, when the normally closed contact of the first relay is in an open state, the second relay is connected to the circuit where the first output terminal of the controller is located, and when the first output terminal of the controller does not output a high-level signal, the normally open contact of the second relay is in an open state, that is, the paper tray acceleration device stops working at this time.

[0055] It is understood that in the embodiments of the present application, a touch screen connected to the controller may be provided, but is not limited to, to determine whether the remaining amount of the roll paper in the tail frame of the paper tray is within a preset remaining amount range through instructions received by the touch screen. For example, when a user manually identifies that the remaining amount of the roll paper in the tail frame of the paper tray is within the preset remaining amount range through observation, a confirmation control for indicating that the remaining amount of the roll paper in the tail frame of the paper tray is within the preset remaining amount range may be selected on the touch screen, or an output control for indicating that a high-level signal is output to the first relay may be selected on the touch screen, so that the controller controls the second output terminal to output a high-level signal to the first relay according to the instruction of the touch screen. Here, the preset remaining amount range may be, but is not limited to, 20% to 40% of the entire roll paper, and is not limited thereto.

[0056] As an optional embodiment of the present application, the balance control system further includes a third relay, a third relay is provided between the third output terminal of the controller and the ground terminal, and a normally open contact of the third relay is provided between the paper tray consumption reduction signal output terminal of the winder and the paper tray tail frame consumption reduction device;

[0057] After the second output terminal of the controller outputs a high level signal to the first relay, the method further includes:

[0058] The third output terminal of the controller outputs a high level signal to the third relay, so that the normally open contact of the third relay is converted from an open state to a conductive state.

[0059] In an embodiment of the present application, a third relay for controlling whether the paper tray tail frame energy reduction device operates normally may also be provided. The third relay may be provided between the third output terminal of the controller and the ground terminal, and the normally open contact of the third relay is provided between the paper tray energy reduction signal output terminal of the winder and the paper tray tail frame energy reduction device, so that when the third relay receives a high-level signal output by the third output terminal of the controller, the normally open contact of the third relay is converted from an off state to an on state, thereby conducting the circuit between the paper tray energy reduction signal output terminal of the winder and the paper tray tail frame energy reduction device, that is, the paper tray tail frame energy reduction device can receive the paper tray energy reduction signal and perform energy reduction processing on the splicing of the paper tray; and when the third relay does not receive a level signal, the normally open contact of the third relay is in an off state or is converted from an on state to an off state, thereby breaking the circuit between the paper tray energy reduction signal output terminal of the winder and the paper tray tail frame energy reduction device, that is, the paper tray tail frame energy reduction device cannot operate normally. It can be understood that the paper tray tail frame consumption reduction device can be used to reduce the rotation rate of the paper tray, that is, to reduce the splicing speed of the paper roll. Of course, the splicing process of the paper roll can also be stopped directly. The specific structure of the paper tray tail frame consumption reduction device is a conventional technology in this field and will not be elaborated here.

[0060] Specifically, after the second output end of the controller outputs a high-level signal to the first relay, that is, after the paper tray acceleration device stops working, a high-level signal can be output to the third relay based on the third output end of the controller to connect the circuit between the paper tray consumption reduction signal output end of the winding machine and the paper tray tail frame consumption reduction device, that is, the paper tray tail frame consumption reduction device can perform consumption reduction processing on the splicing of the paper tray after receiving the paper tray consumption reduction signal, thereby realizing the switching of the acceleration control of the paper tray to the consumption reduction control of the paper tray tail frame.

[0061] Step 104 : When the second input end of the controller receives the enable signal output by the paper tray acceleration signal output end of the winder, the clock pulse signal output by the clock pulse signal output end of the winder is obtained based on the first input end of the controller.

[0062] Specifically, after the controller's second output terminal outputs a high-level signal to the first relay, the controller's second input terminal can also receive an enable signal output by the paper tray acceleration signal output terminal of the winder at a preset time interval. It can be understood that when the enable signal is received, it indicates that the paper tray acceleration device can now operate normally, that is, the accelerated splicing process of the roll paper is restored, and the clock pulse signal output by the clock pulse signal output terminal of the winder can be obtained based on the first input terminal of the controller. Here, the signals output by the winder are all controlled and output by the controller corresponding to the winder, and have no correlation with the controller in the surplus control system mentioned in this application.

[0063] Step 106: Count the clock pulse signal, and when it is detected that the number of clock pulse signals exceeds a preset threshold, output a high-level signal to the second relay based on the first output terminal of the controller, so that the normally open contact of the second relay is converted from an open state to a conductive state.

[0064] Specifically, after obtaining the clock pulse signal output by the clock pulse signal output end of the winding machine based on the first input end of the controller, it is also possible but not limited to starting a high-speed counter to count the received clock pulse signal, and when it is detected that the number of the clock pulse signal exceeds the preset number threshold, it indicates that the accelerated splicing process of the roll paper can be restored at this time, and then a high-level signal is output to the second relay based on the first output end of the controller, so that the normally open contact of the second relay is converted from the disconnected state to the on state, that is, the paper tray acceleration device receives the paper tray acceleration signal and continues the splicing process of the roll paper.

[0065] As another option of the embodiment of the present application, the balance control system further includes a touch screen connected to the third input terminal of the controller;

[0066] Before counting the clock pulse signal, it also includes:

[0067] A preset number threshold for obtaining user input based on the touch screen;

[0068] The preset number threshold is sent to a preset storage path of the controller.

[0069] In the embodiment of the present application, a preset number threshold value input by the user can also be obtained through a set touch screen to meet the user's demand for controlling the remaining amount of the roll paper.

[0070] See here Figure 2 The structural connection diagram of a margin control system provided by an embodiment of the present application is shown as follows: Figure 2As shown, the touch screen power supply can be connected to the cigarette making machine's public 24V for power supply. The touch screen can also communicate with the S7-200 PLC via Ethernet to adjust the tail frame margin parameters. A Siemens S7-200 PLC is installed in the ZJ17 cigarette making machine SE electrical cabinet. This PLC is powered by 24V positive and 24V negative terminals. Using a single-core cable, connect I0.0 to terminal 21 of the X21 terminal block, the output line of the ZJ17 cigarette making machine's "RCP Single Clock Pulse B13." Connect input point I0.1 to the output point of the ZJ17 cigarette making machine control PLC SE paper tray acceleration signal. The PLC output point Q0.3 is connected to the A1 pin of relay K1, the electrical appliance A2 pin is connected to the negative pole of 24V, the normally open contact of relay K1 is connected to the PLC output point Q0.0, the normally closed contact of relay K1 is connected to the output point of the ZJ17 cigarette making machine control PLC SE paper tray acceleration signal, and the common contact of relay K1 is connected to the coil A1 pin of the cigarette making machine paper tray acceleration relay A23.

[0071] When the PLC receives a command from the touch screen, it controls output point Q0.3 to energize relay K1's coil, closing the normally open contacts of relay K1 and switching the paper tray acceleration control to the paper tray tail frame consumption reduction device. When PLC input point I0.1 receives the paper tray acceleration enable signal from the cigarette making machine, a high-speed counter is activated within the PLC. High-speed input point I0.0 counts the RCP cigarette rod clock pulses of the ZJ17 cigarette making machine. When the high-speed counter reaches the value set for the delayed splicing on the paper tray tail frame consumption reduction device touch screen, it controls output point Q0.0 to energize the cigarette making machine's paper tray acceleration relay A23, accelerating the paper tray splicing and thereby reducing the remaining paper tray tail frame.

[0072] In the embodiment of the present application, the paper roll residue is reduced by adopting an external residue control system. For the original equipment, there is no need to modify the main program or transform the equipment itself. While reducing the paper roll tail frame residue, the cost of equipment transformation is reduced. In addition, the control system can also be directly used on other ZJ17 units and is highly reproducible.

[0073] As another optional embodiment of the present application, before detecting that the remaining amount of the roll paper in the tail frame of the paper tray is within a preset remaining amount range, the method further includes:

[0074] Acquiring a roll paper remaining distance of a paper tray tail frame based on a distance measuring sensor, and generating a roll paper remaining thickness curve according to at least two roll paper remaining distances;

[0075] At least two splicing speeds are determined according to the roll paper remaining thickness curve, and based on the at least two splicing speeds and the paper tray acceleration parameter of the winder, it is determined whether the roll paper remaining in the paper tray tail frame is within a preset remaining range.

[0076] In the embodiment of the present application, the distance data collected by the distance measuring sensor can be combined with data processing to effectively determine in real time whether the roll paper remaining in the tail frame of the paper tray is within the preset remaining range.

[0077] Specifically, a distance sensor can be used to obtain real-time information about the remaining paper roll distance at the rear frame of the paper tray. This distance can be understood as the distance between the distance sensor and the surface of the paper roll. The distance sensor can be, but is not limited to, located directly above the rear frame of the paper tray. A paper roll thickness curve can be generated based on the remaining paper roll distances corresponding to at least two moments in time. Optionally, the initial value of this paper roll thickness curve can correspond to the remaining paper roll distance before the paper roll is spliced ​​(which can be 0 at any given moment), and the remaining paper roll distance gradually increases over time.

[0078] Next, after the roll paper remaining thickness curve is generated, the roll paper remaining thickness curve may be divided into at least two sub-curves according to a preset time interval, but is not limited to it. The time interval corresponding to each sub-curve is the preset time interval.

[0079] Then, the ratio between the preset time intervals can be calculated based on the difference between the roll paper remaining distance corresponding to the first moment and the roll paper remaining distance corresponding to the last moment in each sub-curve. This ratio can be understood as the splicing speed of the roll paper at each time interval during the splicing process. It can be understood that when the splicing speed corresponding to each time interval remains consistent or approximately consistent, it indicates that the roll paper is in a uniform splicing state at this time; when the splicing speed corresponding to each time interval is inconsistent, it indicates that the roll paper is in an accelerated splicing state at this time.

[0080] It is possible that when it is detected that the difference between any two splicing speeds is within a preset difference range, it indicates that the roll paper is in a uniform splicing state at this time, and then the average of all splicing speeds can be calculated to obtain the average splicing speed, and when it is detected that the difference between the average splicing speed and the paper tray acceleration parameter of the winder is within the preset difference range, it indicates that the winder is in a normal splicing process at this time, and the roll paper remaining distance at the current moment can be obtained based on the above-mentioned distance measuring sensor, so that when the roll paper remaining distance at the current moment is within the preset distance range, it can be determined that the roll paper remaining in the paper tray tail frame is within the preset remaining range.

[0081] Possibly, when it is detected that the difference between any two splicing speeds is not within the preset difference range, it indicates that the paper roll is in an accelerated splicing state at this time, and then the ratio between the difference between any two adjacent splicing speeds and the preset time interval can be calculated to obtain the corresponding splicing acceleration, and the splicing acceleration range can be obtained based on the minimum splicing acceleration and the maximum splicing acceleration.

[0082] It can be understood that when it is detected that the paper tray acceleration parameter of the winder is in the splicing acceleration range, it indicates that the winder is in a normal splicing process at this time. The paper roll remaining distance at the current moment can be obtained based on the above-mentioned distance measuring sensor, so that when the paper roll remaining distance at the current moment is in the preset distance range, it can be determined that the paper roll remaining distance of the paper tray tail frame is in the preset remaining range.

[0083] See also Figure 3 , Figure 3 A schematic structural diagram of a paper roll tail frame remainder control device for a paper roll splicing machine provided in an embodiment of the present application is shown.
