[0040] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0041] like Figure 1 to Figure 2 As shown, an embodiment of the present invention provides a multi-drum servo synchronous control experimental platform for a cigarette making machine, comprising: a control component 1, a drive component 2 and a drum component 3.

[0042] The control component 1 includes a human-machine interface 11, a main control IPC 12, a main controller 13 and a sub-controller. The main control IPC 12 is connected to the human-machine interface 11 and the main controller 13 respectively, and the main controller 13 is connected to the sub-controller; the human-machine interface 11 is used for entering parameters for human-machine interaction, the main control IPC 12 is used to collect real-time motion data of the drive component 2 and transmit it to the human-machine interface 11, and is used to transmit data information of the human-machine interface 11 to the main controller 13.

[0043] The driving assembly 2 includes a first servo motor 21 , a second servo motor 22 and a third servo motor 23 , and the first servo motor 21 , the second servo motor 22 and the third servo motor 23 are connected to the sub-controller respectively.

[0044] The drum assembly 3 includes a first drum 31, a second drum 32 and a third drum 33, which are respectively connected to the output shafts of the first servo motor 21, the second servo motor 22 and the third servo motor 23; the cigarette 4 passes through the first drum 31, the second drum 32 and the third drum 33 in sequence. Specifically, a plurality of cigarette release grooves are respectively provided on the first drum 31, the second drum 32 and the third drum 33, and the cigarette release grooves are used to place the cigarette 4. The first drum 31, the second drum 32 and the third drum 33 are respectively connected to a negative pressure source, and the negative pressure source provides negative pressure to the cigarette release grooves of the first drum 31, the second drum 32 and the third drum 33.

[0045] Specifically, after the operator inputs the experimental data information into the human-machine interface 11, the main control IPC 12 transmits the data information of the human-machine interface 11 to the main controller 13, and the main controller 13 transmits the received data information to the sub-controller, and the sub-controller controls the operation of the driving component 2.

[0046] When the first servo motor 21, the second servo motor 22 and the third servo motor 23 fail to be enabled during the enabling process, the sub-controller receives the enabling failure information and transmits the information to the main controller 13, and the main control IPC12 collects the real-time motion data of the first servo motor 21, the second servo motor 22 and the third servo motor 23 transmitted by the main controller 13, and transmits it to the human-machine interface 11. At this time, the human-machine interface 11 reports an error and controls the first servo motor 21, the second servo motor 22 and the third servo motor 23 to stop working, so that the operator can obtain the shutdown information clearly and quickly.

[0047] When in use, the operator inputs the experimental data information through the human-machine interface 11, the main control IPC 12 reads the data information, and transmits the data information to the main controller 13, the main controller 13 transmits the data information of the cigarette machine drum wheel A, the cigarette machine drum wheel B, and the cigarette machine drum wheel C to the sub-controller respectively, and the sub-controller controls the first servo motor 21, the second servo motor 22, and the third servo motor 23 to start enabling, and after successful enabling, the first drum wheel 31, the second drum wheel 32, and the third drum wheel 33 are all returned to the initial position, at which time the first drum wheel 31, the second drum wheel 32, and the third drum wheel 33 are coupled to each other. It should be noted that if the first drum wheel 31, the second drum wheel 32, and the third drum wheel 33 have not returned to the initial position, then the first drum wheel 31, the second drum wheel 32, and the third drum wheel 33 are not coupled to each other, at which time, the human-machine interface 11 reports an error, and controls the first servo motor 21, the second servo motor 22, and the third servo motor 23 to stop working.

[0048] Next, the first drum wheel 31, the second drum wheel 32 and the third drum wheel 33 operate at a set speed ratio, and by gradually adjusting the speed ratio of the first servo motor 21, the second servo motor 22 and the third servo motor 23, the cigarette 4 can pass through the first drum wheel 31, the second drum wheel 32 and the third drum wheel 33 smoothly without being squeezed and deformed due to the misalignment of the grooves between the two drum wheels.

[0049] It should be noted that when the main controller 13 and / or the sub-controller detects that the first drum 31, the second drum 32 and the third drum 33 are not operating according to the set speed ratio, the main control IPC12 collects the stop signal transmitted by the main controller 13 and transmits it to the human-machine interface 11. At this time, the human-machine interface 11 reports an error and controls the first servo motor 21, the second servo motor 22 and the third servo motor 23 to stop working.

[0050] In addition, when the first drum 31, the second drum 32 and the third drum 33 all return to their initial positions, theoretically the first drum 31, the second drum 32 and the third drum 33 are coupled to each other, but due to the continuous operation of the equipment, there are errors in the equipment parts, which result in the first drum 31, the second drum 32 and the third drum 33 not being coupled to each other when they return to their initial positions. Therefore, after the first drum wheel 31, the second drum wheel 32 and the third drum wheel 33 all return to the initial position, the main controller 13 and / or the sub-controller detect whether the first drum wheel 31, the second drum wheel 32 and the third drum wheel 33 are coupled to each other. If the first drum wheel 31, the second drum wheel 32 and the third drum wheel 33 are coupled to each other, then the first drum wheel 31, the second drum wheel 32 and the third drum wheel 33 are controlled not to operate according to the set speed ratio; if the first drum wheel 31, the second drum wheel 32 and the third drum wheel 33 are not coupled to each other, the main controller 13 transmits a stop signal to the main control IPC12. The main control IPC12 collects the stop signal transmitted by the main controller 13 and transmits it to the human-machine interface 11. At this time, the human-machine interface 11 reports an error and controls the first servo motor 21, the second servo motor 22 and the third servo motor 23 to stop working.

[0051] In summary, the present invention can gradually adjust the speed ratio of the first servo motor 21, the second servo motor 22 and the third servo motor 23 according to the above steps. After multiple experiments, it can more accurately study and test the synchronous control technology of the first servo motor 21, the second servo motor 22 and the third servo motor 23, thereby improving the accuracy and stability of the cigarette production process, helping to improve the overall efficiency of cigarette production, and ensuring the consistency of product quality, thereby enhancing market competitiveness.

When in use, the operator inputs the data information of the experiment through the human-machine interface 11, the main control IPC 12 reads the data information and transmits the data information to the main controller 13, the main controller 13 transmits the data information of the cigarette machine drum wheel A, the cigarette machine drum wheel B, and the cigarette machine drum wheel C to the sub-controller respectively, and the sub-controller controls the first servo motor 21, the second servo motor 22 and the third servo motor 23 to start enabling, and after successful enabling, the first drum wheel 31, the second drum wheel 32 and the third drum wheel 33 are all returned to the initial position, at which time the first drum wheel 31, the second drum wheel 32 and the third drum wheel 33 are all returned to the initial position, and ... The first drum wheel 32 and the third drum wheel 33 are coupled to each other, and then the first drum wheel 31, the second drum wheel 32 and the third drum wheel 33 operate at a set speed ratio, and the speed ratio of the first servo motor 21, the second servo motor 22 and the third servo motor 23 is gradually adjusted, so that the cigarette 4 can pass through the first drum wheel 31, the second drum wheel 32 and the third drum wheel 33 smoothly without being squeezed and deformed due to the misalignment of the grooves between the two drum wheels. This can fully simulate the synchronous movement of multiple drum wheels in an actual production environment, and effectively ensure production efficiency and product quality.

[0055] In one embodiment of the cigarette making machine multi-drum servo synchronous control experimental platform of the present invention, in order to improve the stability and rapidity of signal transmission, the main control IPC 12 is connected to the human-machine interface 11 and the main controller 13 respectively through an open architecture (Enthercat).

[0056] In one embodiment of the cigarette making machine multi-drum servo synchronous control experimental platform of the present invention, the sub-controller includes a first servo driver 14, a second servo driver 15 and a third servo driver 16, the first servo driver 14, the second servo driver 15 and the third servo driver 16 are all connected to the main controller 13, and the first servo driver 14, the second servo driver 15 and the third servo driver 16 are respectively connected to the first drum 31, the second drum 32 and the third drum 33.

[0057] The present invention connects the first servo driver 14, the second servo driver 15 and the third servo driver 16 to the main controller 13, and the first servo driver 14, the second servo driver 15 and the third servo driver 16 are respectively connected to the first drum 31, the second drum 32 and the third drum 33, and the first servo driver 14, the second servo driver 15 and the third servo driver 16 respectively control the first drum 31, the second drum 32 and the third drum 33 to work, so that the first drum 31, the second drum 32 and the third drum 33 can be rotated in a speed and position dual-loop control mode.

[0058] In one embodiment of the cigarette making machine multi-drum servo synchronous control experimental platform of the present invention, the control component 1 also includes a first connecting shaft 24, a second connecting shaft 25 and a third connecting shaft 26, the two ends of the first connecting shaft 24 are respectively connected to the output shaft of the first servo motor 21 and the first drum 31, the two ends of the second connecting shaft 25 are respectively connected to the output shaft of the second servo motor 22 and the second drum 32, and the two ends of the third connecting shaft 26 are respectively connected to the output shaft of the third servo motor 23 and the third drum 33.

[0059] The present invention connects the two ends of the first connecting shaft 24 to the output shaft of the first servo motor 21 and the first drum 31 respectively, connects the two ends of the second connecting shaft 25 to the output shaft of the second servo motor 22 and the second drum 32 respectively, and connects the two ends of the third connecting shaft 26 to the output shaft of the third servo motor 23 and the third drum 33 respectively, thereby effectively ensuring that the first drum 31, the second drum 32 and the third drum 33 can rotate stably.

[0060] Furthermore, the first drum wheel 31, the second drum wheel 32 and the third drum wheel 33 have 4 grooves for 18 cigarettes, 4 grooves for 20 cigarettes and 4 grooves for 36 cigarettes respectively.

[0061] In one embodiment of the cigarette making machine multi-drum servo synchronous control experimental platform of the present invention, the coupling formula of the first servo motor 21, the second servo motor 22 and the third servo motor 23 is:

[0062] ni = N / (Ki * Mi);

[0063] Among them, ni represents the rotation speed of drum i, N represents the smoke output speed of the whole machine, Ki represents the number of cigarette slots of drum i, and Mi represents the number of cigarettes in each slot. Through this formula, the synchronous rotation speed of each drum at a given smoke output speed can be accurately calculated.

[0064] According to a second aspect of the present invention, a method for servo synchronization control of multiple drums of a cigarette making machine is provided, such as Figure 3 to Figure 4 As shown, the following steps are included:

[0065] Step S1, obtaining data information of the human-machine interface;

[0066] Step S2, according to the acquired data information, control the first servo motor, the second servo motor and the third servo motor to be enabled, if the first servo motor, the second servo motor and the third servo motor are enabled successfully, execute step S3;

[0067] Step S3, obtaining position information of the first drum, the second drum and the third drum;

[0068] Step S4, judging whether the first drum wheel, the second drum wheel and the third drum wheel are in position according to the acquired position information, and if so, controlling the first drum wheel, the second drum wheel and the third drum wheel to couple with each other;

[0069] Step S5, controlling the first drum, the second drum and the third drum to operate according to a preset speed ratio.

[0070] Specifically, the operator inputs the experimental data information through the human-machine interface, and controls the first servo motor, the second servo motor and the third servo motor to enable according to the obtained data information of the human-machine interface input experiment. If the first servo motor, the second servo motor and the third servo motor are enabled successfully, the position information of the first drum wheel, the second drum wheel and the third drum wheel is obtained, and according to the obtained position information, it is determined whether the first drum wheel, the second drum wheel and the third drum wheel are returned to their positions. If so, the first drum wheel, the second drum wheel and the third drum wheel are controlled to couple with each other, and then the first drum wheel, the second drum wheel and the third drum wheel are controlled to operate according to the preset speed ratio. Continuing the previous step, after multiple experiments, the synchronous control technology of the first servo motor, the second servo motor and the third servo motor can be studied and tested more accurately, which improves the accuracy and stability in the cigarette production process, helps to improve the overall efficiency of cigarette production, and ensures the consistency of product quality, thereby enhancing market competitiveness.

[0072] When the first servo motor, the second servo motor and the third servo motor fail to be enabled, the present invention controls the first servo motor, the second servo motor and the third servo motor to stop rotating, thereby effectively saving the time of the experiment.

[0073] In one embodiment of the multi-drum servo synchronous control method for a cigarette making machine of the present invention, in step S3, if the first drum, the second drum and the third drum are not returned to their positions, the first servo motor, the second servo motor and the third servo motor are controlled to stop rotating.

[0074] In one embodiment of the servo synchronous control method for multiple drums of a cigarette making machine of the present invention, after step S5, the following steps are further included:

[0075] Step S6, obtaining a first speed ratio of the first drum, the second drum and the third drum;

[0076] Step S7, based on the obtained first speed ratio, determine whether the first speed ratio is equal to the preset speed ratio, if so, continue to control the first drum wheel, the second drum wheel and the third drum wheel to operate according to the preset speed ratio; if not, control the first servo motor, the second servo motor and the third servo motor to stop rotating.

[0077] Specifically, in the present invention, during the process of the first drum wheel, the second drum wheel and the third drum wheel operating at a preset speed ratio, the first speed ratio of the first drum wheel, the second drum wheel and the third drum wheel is continuously obtained, and it is determined whether the first speed ratio is equal to the preset speed ratio. When the first speed ratio of the first drum wheel, the second drum wheel and the third drum wheel is equal to the preset speed ratio, the first drum wheel, the second drum wheel and the third drum wheel are continuously controlled to operate at the preset speed ratio; if the first speed ratio of the first drum wheel, the second drum wheel and the third drum wheel is not equal to the preset speed ratio, the first servo motor, the second servo motor and the third servo motor are controlled to stop rotating.
