Description

Technical Field

[0001] The invention relates to the technical field of tobacco production, and in particular to a cleaning device for a rubbing drum wheel of a filter tip assembling machine and an intelligent control system. Background Art

[0002] The filter tipping machine is an important part of the cigarette making machine. Its function is to connect the rolled tipless cigarette to the tip rod. The rubbing drum is a key component in the filter tipping machine. It cooperates with the rubbing board to use friction to make the cigarette and the filter roll relative to each other, and then cooperates with the tipping paper to "roll" the two sections of the cigarette together to form a double-length cigarette, which is then cut to form a single cigarette.

[0003] During the production process, since the production environment is in a negative pressure state, the tipping paper is easily offset, which can easily block the suction holes of the splicing drum. In addition, the tipping paper also has glue, which can easily remain on the surface of the splicing drum. Therefore, it is necessary to stop the machine regularly and clean it with special cleaning tools.

[0004] However, the above cleaning process is time-consuming, and production cannot be carried out during the cleaning process, resulting in low overall production efficiency. Moreover, if the cleaning is not timely, defective products are likely to appear, resulting in increased production costs. Summary of the invention

[0005] The purpose of the present invention is to provide a cleaning device and an intelligent control system for a filter tip assembling machine splicing drum, which solves the problem in the prior art that the splicing drum cannot be cleaned in a timely manner, resulting in defective products, and also solves the problem that the machine needs to be shut down during the cleaning process, resulting in reduced production efficiency.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0070] The embodiment of the invention discloses a filter tip connecting machine rubbing drum cleaning device and an intelligent control system.

[0071] Reference Figures 1 to 3The filter tip assembling machine rubbing drum cleaning device comprises a mounting frame 1, a lifting assembly 2, an air supply assembly 3, a blowing assembly 4 and a cleaning mechanism 5. The mounting frame 1 is positionally adjustable and mounted on the filter tip assembling machine; the lifting assembly 2 is disposed on the mounting frame 1; the air supply assembly 3 is connected to the lifting assembly 2 to drive the lifting assembly 2 to move; the blowing assembly 4 is disposed on the mounting frame 1 and is connected to the air supply assembly 3 and can blow gas toward the rubbing drum; the cleaning mechanism 5 is slidably connected to the mounting frame 1 and is connected to the lifting assembly 2, and the lifting assembly 2 is used to drive the cleaning mechanism 5 to approach or move away from the rubbing drum.

[0072] Specifically, the mounting frame 1 includes a first bracket 11 and a second bracket 12. The first bracket 11 is composed of a plurality of connecting rods fixedly connected in sequence. A long waist-shaped hole is provided on the connecting rod close to the filter tip assembler. A screw threadedly connected to the filter tip assembler is passed through the waist-shaped hole to achieve an adjustable position connection between the mounting frame 1 and the filter tip assembling paper. The two can also be connected by means of snap connection instead of screw connection. The specific design can be based on the actual application scenario, and the present invention does not limit this. The second bracket 12 is fixedly connected to the end of the first bracket 11 away from the waist-shaped hole. A plurality of threaded holes can be provided at intervals on the second bracket 12, and any of the threaded holes is passed through a screw that can be fixedly connected to the first bracket 11 to achieve relative position adjustment between the second bracket 12 and the filter tip assembler.

[0073] The second bracket 12 is in the shape of a long strip to match the axial length of the splicing drum. The lifting assembly 2 is arranged above the second bracket 12 and can partially pass through the second bracket 12. The cleaning mechanism 5 is arranged below the second bracket 12 and is slidably connected to the second bracket 12. The cleaning mechanism 5 is connected to the lifting assembly 2, and the cleaning mechanism 5 can clean the surface of the splicing drum. A blowing assembly 4 is arranged on the side of the second bracket 12, and the blowing assembly 4 can spray gas toward the splicing drum, and the gas can be high-pressure gas. The air supply assembly 3 is connected to the lifting assembly 2 and the blowing assembly 4 through a pipeline, which can produce high-pressure gas that has been filtered and dried, and the lifting assembly 2 can use a cylinder as a power source, and control the flow direction of the gas through an electromagnetic valve, so that the gas can be diverted to the lifting assembly 2 to realize the movement of the lifting assembly 2, and can also be diverted to the blowing assembly 4 to spray the splicing drum.

[0074] Before the splicing drum is in operation, the mounting frame 1 is mounted on the filter tip assembling machine and its position relative to the splicing drum is adjusted. After the mounting frame 1 is fixed on the filter tip assembling machine, the air supply assembly 3 is started to generate high-pressure gas, and the position of the cleaning mechanism 5 is adjusted through the lifting assembly 2 to ensure that the cleaning mechanism 5 forms effective contact with the splicing drum, so as to clean the splicing drum when it is in operation. At the same time, the air supply assembly 3 can guide the gas to the spray assembly 4, and the spray assembly 4 sprays gas to the splicing drum to blow away dust, etc., so as to improve the cleaning effect. In this way, the splicing drum cleaning device of the filter tip assembling machine can clean the splicing drum during operation without stopping the machine, saving the time spent on cleaning, effectively improving the overall production efficiency, and at the same time ensuring that the cleanliness of the splicing drum meets the requirements, reducing the possibility of defective products, and reducing production costs. Moreover, the lifting component 2 and the blowing component 4 are both supplied with air by the blowing component 4, which can not only save the number of power sources and reduce the complexity of the structure, thereby reducing the space occupied, but also reduce energy consumption and improve the environmental performance of the cleaning process.

[0075] Reference Figure 4 Optionally, the gas supply assembly 3 includes an injection pipe 31, a blow pipe 32 and a return pipe 33. One end of the injection pipe 31 is connected to the gas source, and the other end is connected to the gas inlet of the lifting assembly 2; one end of the blow pipe 32 is connected to the injection pipe 31, and the other end is connected to the blow assembly 4; one end of the return pipe 33 is connected to the gas outlet of the lifting assembly 2, and the other end is connected to the gas source.

[0076] Specifically, the gas source can be a vacuum air pump, one end of the gas injection pipe 31 is sealed and connected to the gas injection port of the vacuum air pump, and the other end is connected to the air inlet of the lifting assembly 2. The return pipe 33 is arranged in parallel with the gas injection pipe 31 to be able to return the gas to the gas source, so that the lifting assembly 2 can achieve reciprocating motion. A connection port can be opened on the gas injection pipe 31, one end of the blowing pipe 32 is sealed and connected to the connection port, and the other end is connected to the blowing assembly 4.

[0077] By setting the air inlet pipe 36, the air return pipe 33 and the blowing pipe 32, when the lifting component 2 needs to be moved, the gas is guided into the lifting component 2 by the air injection pipe 31, or the gas is guided out from the lifting component 2 by the air return pipe 33. During the cleaning process, the air injection pipe 31 can be continuously ventilated, and the gas can enter the blowing pipe 32 and be guided into the blowing component 4 by the blowing pipe 32. The blowing component 4 can then spray the gas toward the splicing drum, thereby achieving the goal of only setting one air source to drive the lifting component 2 to move and achieve the effect of blowing cleaning.

[0078] Optionally, the gas supply assembly 3 further includes a gas processor 34. The gas inlet of the gas processor 34 is connected to the gas source through the gas inlet pipe 36, and the gas outlet of the gas processor 34 is provided with a control valve 35, which is connected to the gas injection pipe 31 and the gas return pipe 33 respectively.

[0079] Specifically, the gas processor 34 can process the gas, such as filtering impurities contained in the gas and absorbing moisture in the gas, thereby reducing the possibility of forming water vapor and causing yellow spot smoke when the gas is sprayed onto the working surface of the splicing drum. The specific gas processor 34 can be designed with reference to the prior art, and the present invention is not limited to this. One side of the gas processor 34 is connected to the gas source, and the other side is provided with an air intake pipe 36. The end of the air intake pipe 36 away from the gas processor 34 is provided with a solenoid valve as a control valve 35. The openings on both sides of the control valve 35 are provided with throttle valves 351. Two openings are opened on the side of the control valve 35 away from the air intake pipe 36. The two openings are respectively connected to the gas injection pipe 31 and the return air pipe 33. It should be understood that the control valve 35 can also adopt other types of valves, which can be specifically designed according to the control requirements of the actual gas circuit.

[0080] By setting up a gas processor 34, the gas is processed before entering the air inlet pipe 36 to ensure that the gas meets the action requirements of the lifting component 2 and the requirements of the working surface of the blowing and rubbing drum wheel. By setting up a solenoid valve, the air inlet pipe 36 can be remotely controlled to be connected with the air injection pipe 31 or the air return pipe 33, so as to flexibly adjust the gas diversion direction.

[0081] Reference Figures 3 to 7 Optionally, the lifting assembly 2 includes a first cylinder 21 and a second cylinder 22. The air inlet of the first cylinder 21 is connected to the air supply assembly 3, and the piston rod of the first cylinder 21 is connected to one end of the cleaning mechanism 5; the air inlet of the second cylinder 22 is connected to the air supply assembly 3, and the piston rod of the second cylinder 22 is connected to the other end of the cleaning mechanism 5.

[0082] Specifically, the first cylinder 21 and the second cylinder 22 are respectively located on both sides of the second bracket 12 along the length direction, and two gas injection pipes 31 are provided. The two gas injection pipes 31 are connected to each other, one gas injection pipe 31 is connected to the air inlet of the first cylinder 21 and the control valve 35, and the other gas injection pipe 31 is connected to the air inlet of the second cylinder 22. The layout of the return air pipe 33 is the same as that of the air inlet pipe 36, which will not be described here. A through hole 121 is opened on the second bracket 12 for the piston rod of the first cylinder 21 or the second cylinder 22 to pass through, and the two piston rods passing through the through hole 121 are fixedly connected to the two ends of the cleaning mechanism 5 respectively.

[0083] The second bracket 12 is in a 7-shape, and its horizontal arm and vertical arm can be fixed together by welding or screw connection. A connecting block 122 is fixedly connected to the vertical arm by bolts. The connecting blocks 122 are arranged in two rows opposite to each other, and a slide rail 123 is fixedly connected to each row of connecting blocks 122. The cleaning mechanism 5 is slidably connected to the slide rail 123.

[0084] By setting the first cylinder 21 and the second cylinder 22, when the gas is guided into the first cylinder 21 and the second cylinder 22 by the gas injection pipe 31, the first cylinder 21 and the second cylinder 22 can act synchronously to slowly drive the cleaning mechanism 5 to slide, and gradually approach the rubbing drum under the guidance of the slide rail 123 to form contact with the rubbing drum. When the cleaning is completed, the gas is guided out of the first cylinder 21 and the second cylinder 22 by the return air pipe 33, thereby driving the cleaning mechanism 5 to reset and move away from the rubbing drum.

[0085] Reference Figures 8 to 10 Optionally, the blowing assembly 4 includes a blowing head 41. The blowing head 41 has a gas injection joint 42 and a plurality of gas injection holes 411 connected to the gas injection joint 42, and the gas injection holes 411 face the splicing drum.

[0086] Specifically, a gas injection joint 42 is provided on one side of the blowing head 41, and the gas injection joint 42 is sealed and connected to the blowing pipe 32. The other side of the blowing head 41 faces the splicing drum, and a plurality of gas injection holes 411 are provided on this side. A connecting channel is provided inside the blowing head 41 to respectively connect the gas injection joint 42 with the plurality of gas injection holes 411. The blowing head 41 can be in the shape of a long strip and extend along the axial direction of the splicing drum, so that the plurality of gas injection holes 411 can be distributed at equal intervals. The blowing head 41 can also be in the shape of a block, and the side surface is an inclined surface or an arc surface, etc., and the plurality of gas injection holes 411 can be distributed at equal angles on the inclined surface or the arc surface, so as to ensure that the gas injection holes 411 can cover the entire working surface of the splicing drum.

[0087] By setting the blowing head 41, the blowing pipe 32 can introduce gas through the gas injection joint 42, and then spray the gas through multiple jet holes 411. The aperture of the jet holes 411 can be gradually reduced to increase the flow rate of the gas, thereby improving the cleaning effect of the gas spraying.

[0088] Optionally, the blowing head 41 has a blowing slope 412 on one side facing the splicing drum, and the plurality of air jet holes 411 are all provided on the blowing slope 412 , and the axes of the plurality of air jet holes 411 intersect.

[0089] Specifically, the blowing head 41 is block-shaped, with a gas injection joint 42 on the back and the above-mentioned blowing slope 412 on the front. The inclination angle of the blowing slope 412 can be 45 degrees, and multiple blowing holes can be distributed at fixed angles on the blowing slope 412. In the present embodiment, four blowing holes are provided, and the axial angle of the four blowing holes is 5°.

[0090] By distributing a plurality of blowing holes at intervals on the blowing slope 412, the gas ejected from the blowing holes can be evenly sprayed onto the working surface of the splicing drum to ensure that the gas can cover the entire axial length of the splicing drum, thereby improving the effect of the blowing cleaning.

[0091] Optionally, the spray assembly 4 further comprises a connecting frame 43. The connecting frame 43 is arranged on the mounting frame 1, and the spray head 41 is arranged on the connecting frame 43 in an adjustable manner.

[0092] Specifically, the connecting frame 43 is L-shaped, and its vertical arm is fixed to the side wall of the second bracket 12 by a fixing screw 433, and its horizontal arm is provided with an adjustment waist-shaped hole 431, and an adjustment screw 432 is passed through the adjustment waist-shaped hole 431, and the adjustment screw 432 is threadedly connected to the top wall of the blowing block. In other embodiments, multiple adjustment holes can also be provided on the horizontal arm to replace the adjustment waist-shaped hole 431, and the adjustment screw 432 can be passed through any of the adjustment holes.

[0093] By setting the connecting frame 43, the position of the blowing head 41 on the connecting frame 43 can be adjusted according to the relative position and spacing between the splicing drum and the blowing head 41, so that the spacing between the blowing head 41 and the working surface of the splicing drum can meet the requirements of the blowing cleaning, thereby improving the cleaning effect of the blowing. The installation and adjustment are achieved by fixing the screws 433 and adjusting the screws 432, which can also make the installation and disassembly of the entire connecting frame 43 convenient, and the adjustment operation is simple, thereby reducing the difficulty of assembly and adjustment.

[0094] Reference Fig.11 and Fig.12 Optionally, the filter tip assembling machine splicing drum cleaning device further comprises a smoke blocking detector 6. The smoke blocking detector 6 is arranged on the mounting frame 1 and is used to detect the splicing drum.

[0095] Specifically, a smoke blockage detector 6 is provided on the side wall of the second bracket 12, which can detect the smoke blockage on the working surface of the splicing drum. During the operation of the cigarette making machine, due to the lack of filters or splicing failure, double filter cigarettes are thrown out from above the splicing drum. After the installation of the cleaning mechanism 5, the space above the splicing drum is further compressed, which may cause smoke blockage on the working surface of the splicing drum. The smoke blockage detector 6 monitors the smoke blockage of the splicing drum in real time and records it. On the one hand, it can detect the occurrence of smoke blockage in time for quick sorting, effectively protecting the cleaning mechanism 5; on the other hand, through the comprehensive statistical analysis of relevant data such as the number of blockages on the working surface of the splicing drum, the number of blockages on the scrubbing board, and the number of missing filters, fault prediction and diagnosis are performed on the filter supply system and the relevant parts of the scrubbing board.

[0096] Optionally, the filter tip assembling machine rubbing drum cleaning device further comprises an adjusting frame 7. The adjusting frame 7 is arranged on the mounting frame 1, and the smoke blocking detector 6 is arranged on the adjusting frame 7 in an adjustable manner.

[0097] Specifically, the adjustment frame 7 is L-shaped, and its horizontal arm is fixed to the second bracket 12 by a locking screw 71, and an adjustment threaded hole 72 is provided on its vertical arm, and a sliding waist-shaped hole 61 is provided on the smoke detector 6. The sliding waist-shaped hole 61 extends in the vertical direction and corresponds to the adjustment threaded hole 72. A screw is passed through the sliding waist-shaped hole 61, and one end of the screw passes through the sliding waist-shaped hole 61 and is threadedly connected in the adjustment threaded hole 72. The specific length of the sliding waist-shaped hole 61 can be designed according to the actual adjustment range of the smoke detector 6. It should be understood that the sliding waist-shaped hole 61 can also be replaced by opening a plurality of through holes 121 on the smoke detector 6, and the specific position adjustable implementation method can be designed according to the actual installation space and size.

[0098] By setting the adjustment frame 7, the position of the smoke detector 6 relative to the splicing drum can be flexibly adjusted to ensure that the smoke detector 6 can smoothly and effectively detect the working surface of the splicing drum. The setting of the adjustment frame 7 can make the smoke detector 6 quickly assembled and disassembled, so as to facilitate the maintenance and replacement of the smoke detector 6.

The servo motor 51 is fixedly mounted on a stepped hole 514 of a motor seat 511, and the motor seat 511 is connected to a slider 512 (see Figure 6 ) is slidably matched with the slide rail 123 on the second bracket 12. A fixing block 211 (see Figure 6 ), the fixing block 211 is fixedly connected to the motor base 511.

[0100] A brush seat 531 is fixedly provided at one end of the motor seat 511 away from the servo motor 51. The brush seat 531 is penetrated by an axial hole 532. The brush shaft 52 is inserted into the axial hole 532. A connecting sleeve 521 is provided at one end of the brush shaft 52. The connecting sleeve 521 is fixedly connected to the driving shaft of the servo motor 51 through a coupling 513, and the other end is fixedly connected to the connecting head 54.

[0101] The end surface of the connector 54 is provided with a bearing seat 543, a deep groove ball bearing is provided in the bearing seat 543, a connecting rod 544 is also provided on the connector 54, the connecting rod 544 passes through the bearing seat 543, and a threaded rod 545 is provided at one end of the connecting rod 544 passing through the bearing seat 543, a fixing threaded hole 522 is provided at one end of the brush shaft 52 away from the coupling 513, and the threaded rod 545 can be threadedly connected with the fixing threaded hole 522, so as to achieve a fixed connection between the brush shaft 52 and the connector 54. A connecting portion 541 is provided on the side wall of the bearing seat 543, a connecting threaded hole 542 is provided on the end surface of the connecting portion 541, and a connecting screw is provided at the end of the piston rod of the second cylinder 22, and the connecting screw can be screwed into the connecting threaded hole 542.

[0102] A mounting through hole 533 is provided in the brush sleeve 53, the brush seat 531 is passed through the mounting through hole 533, and the brush sleeve 53 is located between the connecting head 54 and the brush seat 531, a first key groove 523 is provided on the side wall of the brush shaft 52, and a second key groove 534 is opened on the inner wall of the brush sleeve 53, and the first key groove 523 and the second key groove 534 are connected by a key to fix the brush sleeve 53 on the brush shaft 52 and ensure that the brush sleeve 53 can rotate synchronously with the brush shaft 52.

[0103] The brush sleeve 53 includes a nylon brush 535 and an end cam 536 arranged at the end of the nylon brush 535. A mounting platform 537 is arranged on the brush seat 531. A roller bearing 538 is arranged on the side of the mounting platform 537 close to the end cam 536. The roller bearing 538 is adapted to the end cam 536.

[0104] When the piston rods of the first cylinder 21 and the second cylinder 22 extend or retract, they can drive the motor seat 511 and the connecting head 54 to slide down or up synchronously, so that the brush sleeve 53 is close to or away from the rubbing drum.

[0105] The intelligent control system includes a communication module, a control module, and a filter tip assembling machine splicing drum cleaning device as described above. The control module is in communication connection with the communication module; the filter tip assembling machine splicing drum cleaning device is in communication connection with the control module and the communication module. The communication module is used to obtain the operating status of the filter tip assembling machine splicing drum cleaning device, and the control module is used to control the operation of the filter tip assembling machine splicing drum cleaning device.

[0106] The communication module and the control module may include PLC and control power supply, motor drive power supply, motor current detector, human-machine interface, brushless motor driver, solenoid valve drive module, photoelectric isolation, frequency-voltage converter, relay, signal conversion module, circuit breaker, PLC programmable controller, solenoid valve and other components. The layout of specific components can be designed according to actual control requirements, and the present invention is not limited to this.

[0107] The specific control process of the intelligent control system is:

[0108] 1. Through the upper computer interface, the filter tip assembling machine rubbing drum cleaning device can be operated intuitively and conveniently and relevant parameters can be adjusted and set.

[0109] 2. Automatic cleaning at regular intervals.

[0110] The long-term continuous operation of the cleaning mechanism 5 will greatly reduce its service life and increase costs. Therefore, while achieving the ideal cleaning effect, the realization of timed automatic cleaning can effectively extend the service life of the cleaning mechanism 5 while ensuring the cleaning effect. The required interval time and cleaning time are set by the timer. After the prerequisites for the automatic cycle cleaning of the cleaning mechanism 5 are met (such as: the cigarette making machine is running, the motor current is normal, etc.), the system controls the cleaning mechanism 5 to automatically enter the working position and clean the rubbing drum for the set time. After the cleaning time is over, the system controls the cleaning mechanism 5 to automatically return to the preset position and enter the next cycle timing.

[0111] 3. Monitoring of cigarette making machine operation.

[0112] When the cigarette making machine stops, the cleaning mechanism 5 stops running and returns to the preset position, and the cleaning mechanism 5 is locked to prevent the operator from accidentally starting the cleaning mechanism 5 when the machine is stopped to handle the fault, thereby harming the operator's safety. At the same time, the operation time and shutdown time, number, and duration of the cigarette making machine are recorded to provide data for the calculation of the life of the nylon brush.

[0113] 4. Intelligent control of the above cleaning device.

[0114] Motor overload: Use an ammeter to monitor the motor current in real time and set a threshold to prevent the motor from overloading and heating, which will affect the motor life.

[0115] Motor stall: When the motor stalls, the system controls the cleaning mechanism 5 to leave the working position and locks it to prevent the cleaning mechanism 5 from being damaged by automatic re-cleaning when the relevant fault is not resolved or by the operator forcing a restart in violation of regulations.

[0116] Motor speed monitoring: Through theoretical calculation, when the linear speed of the nylon brush is equal to the linear speed of the splicing drum, the cleaning effect is the best. To ensure the ideal cleaning effect, the speed of the nylon brush must match the speed of the splicing drum. Due to the existence of the cam mechanism, the required starting torque is relatively large. Therefore, the parameters of the starting speed and starting duration are set, and the cleaning mechanism 5 is lowered to the working position only after the speed of the servo motor 51 reaches the preset value. During the cleaning process, due to the uneven distribution of adhesive scale and tipping paper, the resistance of the nylon brush changes all the time, resulting in the instability of the actual speed of the servo motor 51. Therefore, the real-time speed is monitored, and the speed of the servo motor 51 is controlled by PWM to make it close to the theoretical speed.

[0117] 5. Realization of the function of smoke detector 6.

[0118] During the operation of the cigarette making machine, due to lack of filters or splicing failure, double-filter cigarettes are thrown out from the upper left of the splicing drum. After the cleaning mechanism 5 is installed, the space above the splicing drum is further compressed, resulting in smoke blockage above the splicing drum. The smoke blockage detector 6 monitors the smoke blockage above the splicing drum in real time and records it. On the one hand, it protects the cleaning mechanism 5 from being damaged; on the other hand, through the comprehensive statistical analysis of relevant data such as the number of blockages in the upper left of the splicing drum, the number of blockages on the scrubbing board, and the number of missing filters, fault prediction and diagnosis are performed on the filter supply system and the relevant parts of the scrubbing board.

[0119] 6. Life cycle monitoring of consumable parts of cleaning mechanism 5.

[0120] The total operation time of the cigarette machine, the total number of times and total time of the cleaning mechanism 5, and other related data are statistically analyzed and compared with the reference data obtained in the test phase. The system automatically issues relevant maintenance requirements and important dimensional gap adjustment requirements: consumable parts, such as nylon brushes, cams, bearings, etc. Maintenance and replacement. The reference value for adjusting the compression of the nylon brush and the rubbing drum is 0.15-0.20mm.
