Description

Technical Field

[0001] This invention relates to the field of cigarette equipment technology, and in particular to an anti-clogging control device and control method for an M8 cigarette machine. Background Technology

[0002] In the cigarette-making machine's workflow, the joining drum first receives the pre-formed cigarette (also known as the "batch") with the tipping paper already attached from the closing drum. At this point, the suction device inside the joining drum guides the "batch" into a specific tobacco tray, and the suction generated by small holes on the outer surface of the joining drum ensures the tipping paper adheres smoothly to the grooved drum surface. As the "batch" moves to the joining position, the scraper, during its rotation, carries the "batch" out of the tobacco tray and rolls it between the curved surface of the joining drum and the scraper. This is to ensure the tipping paper tightly wraps around the "batch," firmly bonding it with adhesive to form a complete cigarette with a double filter. The wrapped and bonded double-filter cigarette is then securely placed into the tobacco tray. During the rolling process, the preheated scraper quickly dries the glue on the tipping paper, ensuring a good bond. The corkboard (also known as the cork roller or cork assembly) is mainly responsible for accurately wrapping the cork paper with glue onto the tobacco stick and the filter, forming a tobacco stick with double filters.

[0003] As a high-performance cigarette rolling and forming unit, the main malfunctions causing downtime during normal cigarette production of the M8 cigarette rolling machine are clogged rubbing plates and cigarette strip slippage. According to statistics on downtime records from the production line within a week, downtime caused by clogged rubbing plates accounts for 52% of the total downtime. Investigations have shown that the traditional rubbing plate's dynamic position adjustment capability is insufficient, failing to adapt in real time to changes in equipment operating speed and thus further restricting the continuity and stability of the overall production line. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-clogging control device and control method for an M8 cigarette machine, so as to solve the problems mentioned in the background art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A control device for an anti-clogging rubbing plate in an M8 cigarette machine includes a rubbing drum, a positioning plate, a rotary drive, a rubbing plate, a control center, a PLC position driver, a pneumatic buffer, and a cigarette status sensor. The rubbing drum is mounted on the positioning plate, the rotary drive is mounted on the positioning plate, the pneumatic buffer is mounted on the rotary drive, and the rubbing plate is mounted on the end of the pneumatic buffer away from the rotary drive. The pneumatic buffer is used to adjust the contact pressure between the rubbing plate and the cigarette on the rubbing drum. The cigarette status sensor is mounted on the positioning plate and is used to detect the state of the cigarette on the rubbing drum in contact with the rubbing plate. The control center is signal-connected to the cigarette status sensor, the PLC position driver is signal-connected to the control center, and the rotary drive and the pneumatic buffer are signal-connected to the PLC position driver.

[0007] Optionally, a base is installed at the end of the pneumatic buffer away from the rotary drive device. A base plate is connected to the base plate, and a linear motor is provided on the base plate. The rubbing plate is connected to the drive end of the linear motor, and the linear motor is signal-connected to the PLC posture driver. The linear motor is used to adjust the position and posture of the rubbing plate relative to the rubbing drum.

[0008] Optionally, a heat pipe is embedded in the washboard, and the heat pipe is signal-connected to the control center.

[0009] Optionally, a temperature sensor is embedded in the washboard, and the temperature sensor is signal-connected to the control center.

[0010] Optionally, the pneumatic shock absorber is equipped with a pressure sensor, which is connected to the control center via a signal connection.

[0011] A method for controlling the anti-clogging washboard of an M8 cigarette machine includes the following steps:

[0012] Obtain the state of the cigarette stick in contact with the rubbing plate on the rubbing drum;

[0013] Compare the state of the cigarette with the preset state;

[0014] When the cigarette is blocked by the rubbing board, the rotary drive device drives the rubbing board to rotate by a preset angle α.

[0015] When a cigarette is missing a filter, missing a tobacco section, or is experiencing a burst of smoke, a linear motor drives a rubbing plate to adjust its position relative to the rubbing drum.

[0016] The beneficial effects of this invention are:

[0017] The M8 cigarette machine anti-clogging rubbing plate control device provided by this invention can dynamically adjust the position of the rubbing plate, adapt to the working conditions caused by changes in equipment operating speed in real time, and further ensure the continuity and stability of the overall production line.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0026] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0029] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] like Figures 1 to 4As shown, the present invention provides an anti-clogging rubbing plate control device for an M8 cigarette machine, including a rubbing drum 100, a positioning plate 200, a rotary drive device 300, a rubbing plate 400, a control center 500, a PLC position driver 600, a pneumatic buffer 700, and a cigarette status sensor 800. The components include a rubbing drum 100 mounted on a positioning plate 200, a rotary drive device 300 mounted on the positioning plate 200, a pneumatic buffer 700 mounted on the rotary drive device 300, a rubbing plate 400 mounted on the end of the pneumatic buffer 700 away from the rotary drive device 300, and the pneumatic buffer 700 used to adjust the contact pressure between the rubbing plate 400 and the cigarette on the rubbing drum 100. A cigarette status sensor 800 mounted on the positioning plate 200 is used to detect the status of the cigarette on the rubbing drum 100 in contact with the rubbing plate 400. A control center 500 is connected to the cigarette status sensor 800 via signal connection. A PLC position driver 600 is connected to the control center 500 via signal connection. The rotary drive device 300 and the pneumatic buffer 700 are connected to the PLC position driver 600 via signal connection.

[0031] The M8 cigarette machine anti-clogging rubbing plate control device provided by this invention uses a cigarette status sensor 800 to detect the contact state of cigarettes on the rubbing drum 100 with the rubbing plate 400 and transmits the signal to a control center 500. The control center 500 compares the signal transmitted by the cigarette status sensor 800 with preset status information and determines the contact state of the cigarettes on the rubbing drum 100 with the rubbing plate 400 after analysis. When the cigarette status indicates that the rubbing plate 400 is blocked, the control center 500 sends a signal to a PLC position driver 600. The PLC position driver 600 controls a rotary drive device 300 to drive a pneumatic buffer 700 to rotate by a preset angle α. The pneumatic buffer 700 drives the rubbing plate 400 to rotate by a preset angle α, facilitating the cleaning of the rubbing plate 400 by the operator and preventing damage to the equipment due to clogging by the fed cigarettes.

[0032] For example, the control center 500 and the cigarette status sensor 800 can be connected by electrical connection or Ethernet connection.

[0033] In some embodiments, a base 401 is mounted on the end of the pneumatic buffer 700 away from the rotary drive device 300. A base plate 402 is connected to the base 401, and a linear motor 403 is mounted on the base plate 402. The rubbing plate 400 is connected to the drive end of the linear motor 403, and the linear motor 403 is signal-connected to the PLC posture driver 600. The linear motor 403 is used to adjust the position and orientation of the rubbing plate 400 relative to the rubbing drum 100. Through this scheme, when the cigarette is missing a filter, missing a tobacco segment, or is experiencing a burst of smoke, the control center 500 sends a signal to the PLC posture driver 600. The PLC posture driver 600 controls the linear motor 403 to drive the rubbing plate 400, thereby adjusting the position and orientation of the rubbing plate 400 relative to the rubbing drum 100, thus preventing the rubbing plate 400 from becoming clogged. Defective cigarettes are then removed by the rejection drum.

[0034] Optionally, the linear motor 403 includes two servo motors, which control the position and angle of the washboard 400 in three-dimensional space to achieve real-time dynamic adjustment of the washboard 400.

[0035] In some embodiments, a heat pipe 404 is embedded in the washboard 400, and the heat pipe 404 is signal-connected to the control center 500. A temperature sensor 405 is embedded in the washboard 400, and the temperature sensor 405 is signal-connected to the control center 500. The temperature sensor 405 detects the temperature state of the washboard 400 and transmits the temperature signal of the washboard 400 to the control center 500. The control center 500 analyzes the temperature state of the washboard 400 and determines whether the temperature state of the washboard 400 is lower than a preset temperature. When the temperature state of the washboard 400 is lower than the preset temperature, the control center 500 controls the heat pipe 404 to heat the washboard 400. When the temperature state of the washboard 400 reaches the preset temperature, the control center 500 controls the heat pipe 404 to stop heating the washboard 400.

[0036] In some embodiments, the pneumatic buffer 700 is equipped with a pressure sensor, which is signal-connected to the control center 500. The pressure sensor is used to detect the contact pressure between the rubbing plate 400 and the cigarette on the rubbing drum 100. Through this scheme, the pressure sensor detects the current contact pressure between the rubbing plate 400 and the cigarette on the rubbing drum 100, and transmits the current contact pressure signal to the control center 500. The control center 500 analyzes the current contact pressure and compares it with a preset pressure. When the current contact pressure is less than the preset pressure, the control center 500 controls the pneumatic buffer 700 to increase the contact pressure of the rubbing plate 400 on the cigarette on the rubbing drum 100; when the current contact pressure is greater than the preset pressure, the control center 500 controls the pneumatic buffer 700 to decrease the contact pressure of the rubbing plate 400 on the cigarette on the rubbing drum 100. The above solution can dynamically adjust and constantly control the contact pressure between the cigarette and the rubbing plate 400, ensuring that the cigarette is subjected to appropriate pressure during transportation and does not clog the rubbing plate 400 due to excessive pressure. At the same time, it can avoid insufficient pressure leading to loose connection and reduce the occurrence of rubbing plate 400 clogging.

[0037] The control center 500 can automatically optimize the working state of the washboard 400 according to the preset algorithm, ensuring that the cigarette stick, filter rod and tipping paper are tightly and smoothly combined during the washing process, thereby significantly reducing the risk of the washboard 400 being blocked due to improper cigarette manufacturing or foreign objects.

[0038] like Figures 1 to 4 As shown, the present invention also provides a method for controlling the anti-clogging washboard of an M8 cigarette machine, comprising the following steps:

[0039] Obtain the state of the cigarette in contact with the rubbing plate 400 on the rubbing drum 100;

[0040] Compare the state of the cigarette with the preset state;

[0041] When the cigarette is blocked by the rubbing plate 400, the rotary drive device 300 drives the rubbing plate 400 to rotate by a preset angle α; specifically, the rotary drive device 300 drives the pneumatic buffer 700 to rotate by a preset angle α, and the pneumatic buffer 700 drives the rubbing plate 400 to rotate by a preset angle α.

[0042] When the cigarette is in a state of missing filter, missing tobacco section, or bursting smoke, the linear motor 403 drives the rubbing plate 400 to adjust the position and posture of the rubbing plate 400 relative to the rubbing drum 100.

[0043] Specifically, the control center 500 stores the required preset state data and compares the cigarette's state with the preset state. The preset states include a clogged flush plate 400, a missing filter, a missing tobacco segment, or a cigarette experiencing a burst of smoke. After comparing the cigarette's state with the preset state, the control center 500 determines whether the cigarette's state matches the preset state.

[0044] This invention enables dynamic adjustment of the position of the washboard 400, which can adapt to the working conditions caused by changes in equipment operating speed in real time, further ensuring the continuity and stability of the overall production line.

[0045] All standard parts used in this invention can be purchased commercially, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods for each part all employ mature methods from existing technologies. The machinery, parts, and equipment all use conventional models from existing technologies, and the circuit connections use conventional connection methods from existing technologies, which will not be detailed here. Any content not described in detail in this specification belongs to existing technology known to those skilled in the art.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
