Description
Technical Field
[0001] The invention relates to the technical field of cigarette manufacturing equipment / process, and in particular to a control method of a cigarette splicing timing control system of a YJ27 cigarette making machine. Background Art
[0002] The YJ27 cigarette making machine is a key equipment in the tobacco processing process. Its performance directly affects the cost and efficiency of cigarette production. The action of the rubbing plate at the MAX position of the YJ27 cigarette making machine is one of the important functions of the YJ27 cigarette making machine. In the prior art, when the machine is just started, due to the unstable transmission of the filter and the cork paper, and the rubbing plate is in the rubbing position, the rubbing of cigarettes is prone to disorder and the rubbing plate is blocked, resulting in frequent machine shutdowns and large loss of raw materials.
[0003] The existing shutdown system for the rubbing plate blockage mainly relies on a mechanical structure to achieve it. When the cigarettes are blocked and the iron sheet is touched, the photoelectric switch B50 at the rubbing plate position senses the iron sheet and reports a rubbing plate blockage fault. When the rubbing plate position is blocked, the photoelectric switch B50 often cannot be triggered (a trigger error occurs), and a large number of cigarettes are accumulated on the drum wheel, causing the drum wheel to be misaligned, causing equipment damage and increasing maintenance time. In the prior art, the rubbing plate is prone to blockage when the machine is started, and the rubbing plate is not shut down in time due to blockage, resulting in high production costs and low equipment production efficiency. Therefore, it is an urgent need in this field to develop a control method for the cigarette rubbing timing control system of a new YJ27 cigarette making machine to improve the control accuracy and response speed of the rubbing plate action, reduce production costs, and improve production efficiency. Summary of the invention
[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a control method for the cigarette rubbing and splicing timing control system of a YJ27 cigarette making machine. The control method of the cigarette rubbing and splicing timing control system is redesigned. The cigarette rubbing plate movement is controlled in time by calculating the number of cigarettes, thereby achieving accurate and rapid cigarette rubbing plate movement and blockage shutdown control, effectively avoiding the problem of cigarette rubbing plate blockage when the machine is started and the untimely shutdown problem caused by cigarette rubbing plate blockage, reducing production costs and improving production efficiency.
[0005] In order to achieve the above object, the technical solution adopted by the present invention is: A control method for a cigarette rubbing timing control system of a YJ27 type cigarette making machine, the control system comprises a PLC controller, a high-speed photoelectric switch B1, a high-speed photoelectric switch B2, a single-control solenoid valve, a MAX PLC controller, a MAX rubbing plate position photoelectric switch B50, a machine operation signal, a machine stop signal, and a machine high-speed signal, wherein the high-speed photoelectric switch B1, the high-speed photoelectric switch B2, the MAX rubbing plate position photoelectric switch B50, the machine operation signal, the machine stop signal, and the machine high-speed signal are electrically connected to the PLC controller as an input end of the PLC controller; the PLC controller is electrically connected to the single-control solenoid valve, and the output end of the PLC controller is electrically connected to the single-control solenoid valve to control the action of the cigarette rubbing plate; the PLC controller is electrically connected to the MAX PLC controller to realize timely shutdown after the cigarette rubbing plate is blocked; a photoelectric switch B50 is arranged on one side of the cigarette rubbing wheel, a high-speed photoelectric switch B1 is arranged on one side of the transition wheel, and a high-speed photoelectric switch B2 is arranged on one side of the transmission wheel; the control method comprises: (a) The cigarette making machine starts, and cigarettes pass through the transition wheel of the YJ27 cigarette making machine. The high-speed photoelectric switch B1 continuously sends out pulse signals, and the high-speed counter HSC-0 in the PLC controller receives the pulse signals sent by the high-speed photoelectric switch B1 and starts counting. When the number of cigarettes passing through the transition wheel reaches the first set value set by the high-speed counter, the PLC controller outputs a signal, and the single-control solenoid valve is energized to drive the cigarette rubbing plate to descend; cigarettes continue to pass through the transition wheel. When the number of cigarettes passing through the transition wheel reaches the second set value set by the high-speed counter, the single-control solenoid valve loses power and the cigarette rubbing plate returns to its normal position; (b) The machine starts running, and another high-speed counter HSC-1 in the PLC controller simultaneously receives the pulse signal from the high-speed photoelectric switch B1, and the high-speed counter HSC-1 counts the cigarettes passing through the transition wheel; when the cigarette reaches the transmission wheel at the position of the high-speed photoelectric switch B2, the high-speed photoelectric switch B2 sends a pulse signal, and the high-speed counter HSC-1 in the PLC controller uses the pulse signal from the high-speed photoelectric switch B2 as a zero reset signal; cigarettes continue to pass on the transmission wheel, and the pulses from the high-speed photoelectric switch B2 continue to reset the high-speed counter HSC-1 to zero; when there are cigarettes on the transition wheel and no cigarettes on the transmission wheel and a certain number is reached, that is, the high-speed counter continues to count and the pulses from the no cigarettes on the transmission wheel reset it to zero, after the count value reaches the set value, the PLC controller sends a washboard jam signal to the MAX PLC controller, the machine stops, and a washboard jam fault is displayed.
[0006] Furthermore, first, configure the high-speed counter in the PLC controller, determine that the pulse input terminal of the high-speed counter HSC-0 is I0.0, the synchronization input terminal is I0.1, and the gate input terminal is I0.3; determine that the pulse input terminal of the high-speed counter HSC-1 is I0.2, and the synchronization input terminal is I0.4; then, remove the input point I16.0 signal input line of the MAX PLC controller A40-A2, that is, the photoelectric switch B50 signal input line, and reconnect it to the PLC controller output signal line Q0.1, and the removed photoelectric switch B50 signal line is connected to the PLC controller input terminal I0.5; the machine running and static signals use the auxiliary normally open and normally closed points of the cutter motor contactor K6 in the original machine MAX control system, and are connected to the PLC controller input terminals I0.6 and I0.1 respectively; the machine high-speed signal uses the signal of the output point Q10.1 of the MAX PLC controller A40-A5, and is connected to the PLC controller input terminal I0.3.
[0007] Furthermore, when the machine starts and the cigarette reaches the transition wheel where the high-speed photoelectric switch B1 is located, the high-speed photoelectric switch B1 is triggered, and the high-speed photoelectric switch B1 sends a pulse signal to the high-speed counter HSC-0 in the PLC controller; the high-speed counter HSC-0 starts counting, and when the count of the high-speed counter in the PLC controller is greater than 1, the comparison instruction in the PLC controller is activated, and at this time the value of the high-speed counter HSC-0 is not greater than 20, and the internal relay M0.0 of the program is in a power-off state, so there is a signal output of Q0.0 in the program, and the PLC controller outputs a high level, and the single-control solenoid valve is energized, and the single-control solenoid valve is energized to drive the cigarette rubbing plate to descend.
[0008] Furthermore, the machine continues to run and the high-speed counter HSC-0 continues to count; when the count value is greater than 20, another comparison instruction in the program is activated, and the internal relay M0.0 of the program is in an energized state, and its normally closed point is disconnected. Therefore, even if the count value is greater than 1, there is no signal output from Q0.0 in the program. At this time, the single-control solenoid valve loses power and controls the cigarette rubbing plate to rise to the normal cigarette rubbing position; after the rubbing plate mechanism completes the above actions, it has completed the actions required to start the machine, and the counter does not need to count anymore.
[0009] Furthermore, when the machine runs at high speed, the high-speed running signal is transmitted to the gate input terminal I0.3 of the high-speed counter in the PLC controller, and the counting stops; when the machine stops, the machine stop signal is transmitted to the synchronous input terminal I0.1 of the high-speed counter in the PLC controller, and the high-speed counter HSC-0 is always reset to zero to ensure that the count value of the high-speed counter HSC-0 is zero when it works next time.
[0010] Furthermore, when the machine is running, the pulse signal emitted by the high-speed photoelectric switch B1 is also input into another high-speed counter HSC-1 in the PLC controller, and the high-speed counter HSC-1 starts counting; when the cigarette is transmitted to the conveying wheel, the pulse signal emitted by the high-speed photoelectric switch B2 is input into the synchronous input end of the high-speed counter HSC-1, and the high-speed counter HSC-1 is continuously reset to zero; when there are cigarettes passing through the transition wheel and no cigarettes passing through the conveying wheel, the high-speed photoelectric switch B1 keeps sending out pulse signals while the high-speed photoelectric switch B2 does not generate pulse signals. At this time, the high-speed counter HSC-1 is no longer reset to zero but keeps counting. When the count value is greater than 30, the PLC controller generates an electrical signal M0.1.
[0011] Furthermore, the electrical signal M0.1 generated by the PLC controller and the signal generated by the original machine's washboard position photoelectric switch B50 are set to an "or" logical relationship in the PLC controller program. When a cigarette passes through the transition wheel and no cigarette passes through the transmission wheel or the original machine's washboard position photoelectric switch B50 is triggered, the PLC controller outputs a signal Q0.1; the PLC controller output signal Q0.1 is transmitted to the input point I16.0 of the MAX PLC controller A40-A2, the machine stops and reports a "washboard blockage" fault.
[0012] Furthermore, considering that when the machine is stationary, the high-speed photoelectric switch B1 at the transition wheel may be triggered to count by mistake, resulting in the initial count value of the high-speed counter HSC-1 not being zero when the machine starts. In this way, after the machine starts, the value of the high-speed counter HSC-1 may be greater than the program setting value 30 when the machine is operating normally without a washboard blockage, thereby falsely reporting a "washboard blockage" fault; to avoid the above situation, the rising edge of the machine operation signal is used to reset the initial value of the high-speed counter HSC-1 to zero, and the machine starts running from a standstill. The input terminal I0.6 of the high-speed counter HSC-1 generates a rising edge to the counter CV terminal, and a "0" value is assigned to the counter.
[0013] The present invention discloses a control method for a cigarette rubbing and splicing timing control system of a YJ27 cigarette making machine, which redesigns the control method for the cigarette rubbing and splicing timing control system, performs timing control on the action of a cigarette rubbing plate by calculating the number of cigarettes, realizes accurate and rapid action of the cigarette rubbing plate and blockage shutdown control, effectively avoids the problem of blockage of the cigarette rubbing plate when the machine is started and the problem of untimely shutdown due to blockage of the cigarette rubbing plate, reduces production costs and improves production efficiency.

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0018] like Figure 1-2 As shown, a control method for a cigarette rubbing timing control system of a YJ27 type cigarette making machine, the control system includes a PLC controller, a high-speed photoelectric switch B1, a high-speed photoelectric switch B2, a single-control solenoid valve, a MAX PLC controller (original / existing), a MAX rubbing plate position photoelectric switch B50 (original / existing), a machine operation signal, a machine stop signal, and a machine high-speed signal, the high-speed photoelectric switch B1, the high-speed photoelectric switch B2, the MAX rubbing plate position photoelectric switch B50, the machine operation signal, the machine stop signal, and the machine high-speed signal are electrically connected to the PLC controller as the input end of the PLC controller; the PLC controller is electrically connected to the single-control solenoid valve, and the output end of the PLC controller is electrically connected to the single-control solenoid valve to control the action of the cigarette rubbing plate; the PLC controller is electrically connected to the MAX PLC controller to realize timely shutdown after the cigarette rubbing plate is blocked; a photoelectric switch B50 is arranged on one side of the cigarette rubbing wheel, a high-speed photoelectric switch B1 is arranged on one side of the transition wheel, and a high-speed photoelectric switch B2 is arranged on one side of the transmission wheel; the control method includes: (a) The cigarette making machine starts, and cigarettes pass through the transition wheel of the YJ27 cigarette making machine. The high-speed photoelectric switch B1 continuously sends out pulse signals, and the high-speed counter HSC-0 in the PLC controller receives the pulse signals sent by the high-speed photoelectric switch B1 and starts counting. When the number of cigarettes passing through the transition wheel reaches the first set value set by the high-speed counter, the PLC controller outputs a signal, and the single-control solenoid valve is energized to drive the cigarette rubbing plate to descend; cigarettes continue to pass through the transition wheel. When the number of cigarettes passing through the transition wheel reaches the second set value set by the high-speed counter, the single-control solenoid valve loses power and the cigarette rubbing plate returns to its normal position; (b) The machine starts running, and another high-speed counter HSC-1 in the PLC controller simultaneously receives the pulse signal from the high-speed photoelectric switch B1, and the high-speed counter HSC-1 counts the cigarettes passing through the transition wheel; when the cigarette reaches the transmission wheel at the position of the high-speed photoelectric switch B2, the high-speed photoelectric switch B2 sends a pulse signal, and the high-speed counter HSC-1 in the PLC controller uses the pulse signal from the high-speed photoelectric switch B2 as a zero reset signal; cigarettes continue to pass on the transmission wheel, and the pulses from the high-speed photoelectric switch B2 continue to reset the high-speed counter HSC-1 to zero; when there are cigarettes on the transition wheel and no cigarettes on the transmission wheel and a certain number is reached, that is, the high-speed counter continues to count and the pulses from the no cigarettes on the transmission wheel reset it to zero, after the count value reaches the set value, the PLC controller sends a washboard jam signal to the MAX PLC controller, the machine stops, and a washboard jam fault is displayed.
[0019] The timing control method of the present invention is a control method for the cigarette rubbing timing control system that is added to the PLC control system of the MAX part of the YJ27 cigarette making machine by an external plug-in method. The timing control system is added with a PLC controller, two high-speed photoelectric switches, and a single-control solenoid valve, and uses machine running, high-speed, and static signals, and changes the signal input point of the original machine's rubbing plate position detection photoelectric switch B50.
[0020] First, configure the high-speed counter in the PLC controller, determine that the pulse input terminal of the high-speed counter HSC-0 is I0.0, the synchronization input terminal is I0.1, and the gate input terminal is I0.3; determine that the pulse input terminal of the high-speed counter HSC-1 is I0.2, and the synchronization input terminal is I0.4; then, remove the input point I16.0 signal input line of the MAX PLC controller A40-A2, that is, the photoelectric switch B50 signal input line, and reconnect it to the PLC controller output signal line Q0.1, and the removed photoelectric switch B50 signal line is connected to the PLC controller input terminal I0.5; the machine running and static signals use the auxiliary normally open and normally closed points of the cutter motor contactor K6 in the original machine MAX control system, and are connected to the PLC controller input terminals I0.6 and I0.1 respectively; the machine high-speed signal uses the signal of the output point Q10.1 of the MAX PLC controller A40-A5, and is connected to the PLC controller input terminal I0.3.
[0021] Furthermore, when the machine starts and the cigarette reaches the transition wheel where the high-speed photoelectric switch B1 is located, the high-speed photoelectric switch B1 is triggered, and the high-speed photoelectric switch B1 sends a pulse signal to the high-speed counter HSC-0 in the PLC controller; the high-speed counter HSC-0 starts counting, and when the count of the high-speed counter in the PLC controller is greater than 1, the comparison instruction in the PLC controller is activated, and at this time the value of the high-speed counter HSC-0 is not greater than 20, and the internal relay M0.0 of the program is in a power-off state, so there is a signal output of Q0.0 in the program, and the PLC controller outputs a high level, and the single-control solenoid valve is energized, and the single-control solenoid valve is energized to drive the cigarette rubbing plate to descend.
[0022] Furthermore, the machine continues to run and the high-speed counter HSC-0 continues to count; when the count value is greater than 20, another comparison instruction in the program is activated, and the internal relay M0.0 of the program is in the energized state, and its normally closed point is disconnected. Therefore, even if the count value is greater than 1, there is no signal output from Q0.0 in the program. At this time, the single-control solenoid valve loses power and controls the cigarette rubbing plate to rise to the normal cigarette rubbing position.
[0023] Furthermore, after the washboard mechanism completes the above-mentioned actions, the actions required for starting the machine have been completed, and the counter does not need to count any more.
[0024] Furthermore, when the machine runs at high speed, the high-speed running signal is transmitted to the gate input terminal I0.3 of the high-speed counter in the PLC controller, and the counting stops; when the machine stops, the machine stop signal is transmitted to the synchronous input terminal I0.1 of the high-speed counter in the PLC controller, and the high-speed counter HSC-0 is always reset to zero to ensure that the count value of the high-speed counter HSC-0 is zero when it works next time.
[0025] When the machine is running, the pulse signal emitted by the high-speed photoelectric switch B1 is also input into another high-speed counter HSC-1 in the PLC controller, and the high-speed counter HSC-1 starts counting; when the cigarette is transmitted to the transmission wheel, the pulse signal emitted by the high-speed photoelectric switch B2 is input into the synchronous input end of the high-speed counter HSC-1, and the high-speed counter HSC-1 is continuously reset to zero; when there are cigarettes passing through the transition wheel and no cigarettes passing through the transmission wheel, the high-speed photoelectric switch B1 keeps sending out pulse signals while the high-speed photoelectric switch B2 does not generate pulse signals. At this time, the high-speed counter HSC-1 is no longer reset to zero but keeps counting. When the count value is greater than 30, the PLC controller generates an electrical signal M0.1.
[0026] Furthermore, the electrical signal M0.1 generated by the PLC controller and the signal generated by the original machine's washboard position photoelectric switch B50 are set to an "or" logical relationship in the PLC controller program. When a cigarette passes through the transition wheel and no cigarette passes through the transmission wheel or the original machine's washboard position photoelectric switch B50 is triggered, the PLC controller outputs a signal Q0.1; the PLC controller output signal Q0.1 is transmitted to the input point I16.0 of the MAX PLC controller A40-A2, the machine stops and reports a "washboard blockage" fault.
[0027] Furthermore, considering that when the machine is stationary, the high-speed photoelectric switch B1 at the transition wheel may be triggered to count by mistake, resulting in the initial count value of the high-speed counter HSC-1 not being zero when the machine starts. In this way, after the machine starts, the value of the high-speed counter HSC-1 may be greater than the program setting value 30 when the machine is operating normally without a washboard blockage, thereby falsely reporting a "washboard blockage" fault; to avoid the above situation, the rising edge of the machine operation signal is used to reset the initial value of the high-speed counter HSC-1 to zero, and the machine starts running from a standstill. The input terminal I0.6 of the high-speed counter HSC-1 generates a rising edge to the counter CV terminal, and a "0" value is assigned to the counter.
[0028] The present invention discloses a control method for a cigarette rubbing and splicing timing control system of a YJ27 cigarette making machine, which redesigns the control method for the cigarette rubbing and splicing timing control system, performs timing control on the action of a cigarette rubbing plate by calculating the number of cigarettes, realizes accurate and rapid action of the cigarette rubbing plate and blockage shutdown control, effectively avoids the problem of blockage of the cigarette rubbing plate when the machine is started and the problem of untimely shutdown due to blockage of the cigarette rubbing plate, reduces production costs and improves production efficiency.
[0029] The above-mentioned implementation modes are for explanation of the present invention rather than limitation of the present invention. It can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
