Description

Technical Field

[0001] The present invention relates to the technical field of cigarette making equipment, and in particular to a control device and a control method for an anti-blocking rubbing plate of an M8 cigarette making machine. Background Art

[0002] In the working process of the cigarette making machine, the splicing drum first receives the cigarette prototype (also known as "group cigarette") with the tipping paper pasted on it from the approaching drum. At this time, the suction device inside the splicing drum will make the "group cigarette" fall into a specific cigarette groove, and the suction generated by the small holes on the outer surface of the splicing drum will ensure that the tipping paper is flatly attached to the drum surface with straight lines. When the "group cigarette" moves to the splicing working position, the scraping plate will take the "group cigarette" out of the cigarette groove during the rotation process and let it roll between the arc surface of the splicing drum and the rubbing board. The purpose of this is to allow the tipping paper to tightly wrap the "group cigarette" and firmly bond it into a complete cigarette with a double filter through an adhesive. The double-filter cigarette that has been wrapped and bonded will be safely placed in the cigarette groove. During the rolling process, the pre-heated rubbing board can quickly dry the glue on the tipping paper to ensure a good bonding effect. The rubbing board (also called the rubbing wheel or rubbing assembly) is mainly responsible for accurately wrapping the tipping paper with glue on the cigarette rod and the filter to form a cigarette rod with a double filter.

[0003] The M8 cigarette making machine is a high-performance cigarette making unit. During normal cigarette production, the main faults that cause it to stop are blockage of the washboard and slipping of cigarette strips. According to the statistics of the downtime records of the production line within a week, the downtime caused by blockage of the washboard accounts for 52% of the total downtime. According to the survey, the traditional washboard position dynamic adjustment ability is insufficient, and it cannot adapt to the working conditions brought about by the change of equipment running speed in real time, which further restricts the continuity and stability of the overall production line.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used 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-blocking rubbing board control device for an M8 cigarette making machine, including a rubbing drum wheel 100, a positioning plate 200, a rotary drive device 300, a rubbing board 400, a control center 500, a PLC posture driver 600, a pneumatic buffer 700 and a cigarette status sensor 800. Among them, the rubbing drum 100 is installed on the positioning plate 200, the rotary drive device 300 is installed on the positioning plate 200, the pneumatic buffer 700 is installed on the rotary drive device 300, the rubbing board 400 is installed on the end of the pneumatic buffer 700 away from the rotary drive device 300, the pneumatic buffer 700 is used to adjust the contact pressure between the rubbing board 400 and the cigarette on the rubbing drum 100, the cigarette status sensor 800 is installed on the positioning plate 200, the cigarette status sensor 800 is used to detect the state of the cigarette on the rubbing drum 100 that is in contact with the rubbing board 400, the control center 500 is signal-connected to the cigarette status sensor 800, the PLC posture driver 600 is signal-connected to the control center 500, the rotary drive device 300 and the pneumatic buffer 700 are signal-connected to the PLC posture driver 600.

[0031] In the M8 cigarette making machine anti-blocking washboard control device provided by the present invention, the cigarette state sensor 800 detects the state of the cigarette on the rubbing drum 100 that contacts the washboard 400 and transmits the signal to the control center 500. The control center 500 compares the signal transmitted by the cigarette state sensor 800 with the preset state information. After analysis, the control center 500 determines the state of the cigarette on the rubbing drum 100 that contacts the washboard 400. When the state of the cigarette is blocking the washboard 400, the control center 500 sends a signal to the PLC posture driver 600. The PLC posture driver 600 controls the rotary drive device 300 to drive the pneumatic buffer 700 to rotate the preset angle α. The pneumatic buffer 700 drives the washboard 400 to rotate the preset angle α, so that the operator can clean the washboard 400 conveniently and prevent the feeding cigarette from blocking and damaging the equipment.

[0032] Exemplarily, the control center 500 and the cigarette status sensor 800 may be connected via electrical connection or Ethernet.

[0033] In some embodiments, a base 401 is installed at one end of the pneumatic buffer 700 away from the rotary drive device 300, and the base 401 is connected to a substrate 402, and a linear motor 403 is arranged on the substrate 402. The washboard 400 is connected to the driving end of the linear motor 403, and the linear motor 403 is connected to the PLC posture driver 600 signal, and the linear motor 403 is used to adjust the position and posture of the washboard 400 relative to the rubbing drum 100. Through the above scheme, when the state of the cigarette is a cigarette without a filter, a cigarette segment, or a burst cigarette, the control center 500 sends a signal to the PLC posture driver 600, and the PLC posture driver 600 controls the linear motor 403 to drive the washboard 400 to adjust the position and posture of the washboard 400 relative to the rubbing drum 100, thereby avoiding the occurrence of the phenomenon of blocking the washboard 400, and the defective cigarettes will be rejected by the rejection drum.

[0034] Optionally, the linear motor 403 includes two servo motors, and the two servo motors respectively control the position and angle posture of the washboard 400 in the 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 connected to the control center 500 by signal. A temperature sensor 405 is embedded in the washboard 400, and the temperature sensor 405 is connected to the control center 500 by signal. 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 the 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 connected to the control center 500 by signal, and the pressure sensor is used to detect the contact pressure between the rubbing plate 400 and the cigarette on the rubbing drum 100. Through the above 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 signal of the current contact pressure to the control center 500, and the control center 500 analyzes the current contact pressure and compares the current contact pressure with the 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 reduce the contact pressure of the rubbing plate 400 on the cigarette on the rubbing drum 100. Through the above scheme, the contact pressure between the cigarette and the washboard 400 can be dynamically adjusted and constantly controlled to ensure that the cigarette is subjected to appropriate pressure during transportation and does not block the washboard 400 due to overpressure. At the same time, insufficient pressure can be avoided to cause loose connection, which can reduce the occurrence of blockage of the washboard 400.

[0037] The control center 500 can automatically optimize the working state of the washboard 400 according to a preset algorithm to ensure that the cigarettes, filter rods and tipping paper are tightly and smoothly combined during the splicing process, thereby significantly reducing the risk of clogging of the washboard 400 due to improper cigarette production or foreign matter.

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

[0039] Obtaining the state of the rubbing drum 100 contacting the cigarette with the rubbing plate 400;

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

[0041] When the cigarette is in the state of blocking the washboard 400, the rotary drive device 300 drives the washboard 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 washboard 400 to rotate by the preset angle α;

[0042] When the cigarette is in the state of lacking a filter, lacking a cigarette segment, or being a smoke-exploded cigarette, the linear motor 403 drives the rubbing board 400 to adjust the position and posture of the rubbing board 400 relative to the rubbing drum 100 .

[0043] Specifically, the required preset state data information is stored in the control center 500, and the state of the cigarette is compared with the preset state through the control center 500. The preset state includes a cigarette with a blocked washboard 400, a missing filter, a missing cigarette segment, or a burst cigarette. After comparing the state of the cigarette with the preset state, the control center 500 determines whether the state of the cigarette is the preset state.

[0044] The present invention can realize dynamic adjustment of the position of the washboard 400, can adapt to the working condition requirements brought about by the change of the equipment running speed in real time, and further ensure the continuity and stability of the overall production line.
