Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cigarette production, in particular to a copper chain cleaning system and method. BACKGROUND

[0002] In the production process of cut tobacco, the cutting process is an important link to ensure the quality of cut tobacco, and the feeding module of the cutting machine (i.e. the copper chain conveying device of the cutting machine) is a key component to ensure the uniformity of cut tobacco. In the actual production process, the material is between the upper copper chain and the lower copper chain, and the cutting machine equipment will exert a large extrusion force on the material. Therefore, the tobacco dust, fragments, tobacco oil and tobacco scale in the material are easy to adhere to the surface of the copper chain and accumulate in the grooves of the copper chain, causing abnormal phenomena such as jamming, deformation, bulging, deviation and misplacement of the copper chain during operation, affecting the feeding effect, and further causing uneven cut tobacco, which seriously affects the quality of cut tobacco. In addition, the deformation of the copper chain also causes serious wear of the cutting machine and the copper chain, resulting in shutdown of the cutting machine due to failure, and increasing the maintenance cost of the equipment.

[0003] Therefore, in order to ensure the quality of cut tobacco and reduce machine wear, production workshop personnel generally clean the surface of the copper chain with a steel wire brush, scraper and other tools after production ends each day or when changing cigarette brands, and remove the tobacco dust and other residues in the grooves of the copper chain. However, since the number of grooves of the copper chain is large, generally up to three or four hundred, and each time the grooves are cleaned manually, the operator needs to hold a steel wire brush or scraper and clean the grooves repeatedly, which is time-consuming and labor-intensive, resulting in low cleaning efficiency of the copper chain. SUMMARY

[0004] The present application aims to solve the technical problem of low efficiency of manual cleaning of the copper chain in the prior art. To solve this problem, the present application provides a copper chain cleaning system and method, which can automatically clean the grooves on the surface of the copper chain, improve the cleaning efficiency of the copper chain, and more easily ensure the cleaning effect of the copper chain by using mechanical cleaning compared with manual operation.

[0045] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below in combination with the drawings.

[0046] Reference Figures 1 to 3 A specific embodiment of the present application provides a copper bar chain cleaning system, which comprises a cleaning module 1, a driving module, and a detection module 5.

[0047] The cleaning module 1 comprises a cleaning driving part 103 and a plurality of protrusions 10221 arranged in a straight line at intervals, the shape of each protrusion 10221 matches the shape of the groove 2011 of the copper strip chain 201 so that the protrusion 10221 can extend into the groove 2011, and the cleaning driving part 103 can drive each protrusion 10221 to repeatedly move in the corresponding groove 2011 to clean the groove 2011; the driving module is connected with the cleaning module 1 and can be used to drive the cleaning module 1 to move away from or close to the copper strip chain 201; the detection module 5 is electrically connected with the cleaning driving part 103 and is used to detect the relative position between each protrusion 10221 and the corresponding groove 2011, and when it is detected that each protrusion 10221 extends into the corresponding groove 2011, a signal is sent to drive the cleaning driving part 103 to drive the protrusion 10221 to repeatedly move in the groove 2011 for a first preset time. Specifically, during the cleaning process of the copper strip chain cleaning system, the copper strip chain 201 runs once every second preset time interval, and the running distance of each time is less than or equal to a preset distance, and the preset distance is the distance between the two protrusions 10221 farthest apart; the second preset time is greater than or equal to the first preset time.

[0048] Generally, the length of the copper strip chain 201 is relatively long, and the length (or the number) of each protrusion 10221 on the cleaning module 1 is limited, so the cleaning of the copper strip chain 201 is usually completed by multiple times. Specifically, the position of the cleaning module 1 can be set to be basically unchanged during each cleaning, and the protrusions 10221 on the module only clean the grooves 2011 on the surface of the copper strip chain 201 in the cleaning area, and after the grooves 2011 on the current copper strip chain 201 in the cleaning area are cleaned, the copper strip chain 201 runs forward (or backward) so that the next section of the copper strip chain 201 runs to the cleaning area to perform cleaning on the section of the copper strip chain 201. Specifically, after a section of the copper strip chain 201 in the cleaning area is cleaned, the copper strip chain 201 runs so that the section of the copper strip chain 201 that has been cleaned moves out of the cleaning area, and the next section of the copper strip chain 201 adjacent to it moves to the cleaning area, and then the cleaning module 1 moves to the position where the protrusions 10221 on it extend into the grooves 2011 of the copper strip chain 201 in the cleaning area, and then the cleaning driving part 103 drives each protrusion 10221 to repeatedly move in the groove 2011, and the accumulated residues such as soot and oil in the groove 2011 are removed by the friction between the protrusion 10221 and the groove 2011. Specifically, in order to better achieve the cleaning effect, the copper strip chain 201 runs each time to a distance less than or equal to the distance between the two protrusions 10221 farthest apart, and the interval time between the two consecutive running of the copper strip chain 201 is greater than or equal to the time of repeatedly driving the protrusion 10221 by the cleaning driving part 103.

[0049] By the technical scheme, during the cleaning process, the copper chain 201 moves intermittently, after the cleaning module 1 finishes cleaning a section of the copper chain 201, the copper chain 201 moves a distance, and the relative positions of the grooves 2011 of the copper chain 201 and the cleaning module 1 are detected by the detection module 5, when the protrusions 10221 on the cleaning module 1 extend into the corresponding grooves 2011, the protrusions 10221 repeatedly move in the grooves 2011 on the surface of the copper chain 201 to clean the residues in the grooves 2011 by the cleaning driving part 103. That is, the power cleaning device is used to replace manual scraping and cleaning of the residues in the grooves 2011 on the surface of the copper chain 201, and the cleaning effect and the cleaning efficiency are improved.

[0050] Specifically, the cleaning module 1, the driving module 2 and the detection module 5 constitute a copper chain cleaning assembly 100, during the specific cleaning, the copper chain cleaning assembly 100 is arranged below the copper chain, specifically, as shown in the figure, Figure 2 The copper chain cleaning system further comprises a supporting module 6, the cleaning module 1 is installed on the supporting module 6, and the supporting module 6 is further used for being connected with the rack 202 of the tobacco cutting machine, so that the cleaning system is fixedly installed on the tobacco cutting machine to facilitate cleaning of the copper chain 201 of the tobacco cutting machine.

[0051] Specifically, the cleaning module 1 further comprises a fixing part 101. Specifically, the fixing part 101 is connected with the supporting module 6, so that the cleaning module 1 can be installed on the supporting module 6.

[0052] Specifically, the cleaning driving part 103 can reciprocate between the first cleaning position and the second cleaning position relative to the fixing part 101 along a first direction (as shown in the X direction of the figure) Figure 3 and Figure 5 , wherein the first direction is perpendicular to the extension direction (as shown in the Y direction of the figure) Figure 3 and Figure 5 of the copper chain 201. That is, the protrusions 10221 can move in the grooves 2011 perpendicularly relative to the extension direction of the grooves 2011, so as to facilitate cleaning of the inner surface of the grooves 2011.

[0053] Specifically, the relative reciprocating motion of the cleaning driving part 103 and the fixing part 101 can be realized in the form of a gear 1032 and a rack 1011. Specifically, the fixing part 101 comprises a rack 1011 arranged along the first direction, the cleaning driving part 103 comprises a motor 1031 and a gear 1032 engaged with the rack 1011, the motor 1031 is connected with the detection module 5, and the output end of the motor 1031 is connected with the gear 1032, the gear 1032 can reciprocate relative to the rack 1011 along the first direction under the drive of the motor 1031.

[0054] Specifically, asFigure 3 As shown, the fixing part 101 includes a strip extending along a first direction. A rack 1011 extending along the first direction is provided on the side of the strip. The cleaning drive part 103 includes a motor 1031. The bottom of the motor 1031 is mounted on the base plate, and the output end of the motor 1031 passes through the base plate and connects to a gear 1032. The cleaning part 102 is mounted on the base plate. When the motor 1031 operates, its output end drives the gear 1032 to rotate. Since the gear 1032 meshes with the rack 1011, and the rack 1011 is relatively fixed on the support module 6, the movement of the gear 1032 along the first direction simultaneously drives the mounting plate, the cleaning part 102 on the mounting plate, and the motor 1031 to move synchronously along the first direction. Furthermore, by adjusting the forward and reverse rotation of the motor 1031, the gear 1032 can be controlled to move either forward or backward along the first direction. In actual operation, the forward and reverse rotation time of motor 1031 can be set according to the actual situation to achieve the cleaning of groove 2011 by protrusion 10221.

[0055] For example, the cleaning module 1 also includes a cleaning section 102, with each protrusion disposed on the cleaning section 102. The cleaning section 102 includes a support plate 1021, a scraper 1022, and fasteners.

[0056] Specifically, the support plate 1021 in the second direction ( Figure 3 and Figure 5 The support plate 1021 (shown in the Z-direction) has a certain length and a first mounting hole is provided at its first end. The first end of the support plate 1021 is located near the copper busbar chain 201 in the second direction. A protrusion 10221 is provided on the scraper 1022, and a second mounting hole 1023 is also provided on the scraper 1022. The scraper 1022 is mounted on the support plate 1021 by fasteners passing through the second mounting hole 1023 and the first mounting hole. Optionally, the scraper 1022 can be a finger plate, that is, the top of the scraper 1022 is provided with the aforementioned protrusion 10221, and the protrusion 10221 is finger-shaped. This shape of the scraper 1022 facilitates cleaning of the groove 2011.

[0057] Specifically, by setting the first mounting hole and the second mounting hole 1023, the position of the scraper 1022 on the support plate 1021 can be adjusted according to actual conditions, so as to facilitate the subsequent cleaning of the protrusions 10221 on the scraper 1022 to the grooves 2011. Optionally, the first mounting hole and / or the second mounting hole 1023 are also holes extending in the second direction, which can be in the shape of a waist-shaped hole, a strip-shaped hole, etc. In some other embodiments of the present application, the first mounting hole and / or the second mounting hole 1023 can also be a plurality of holes arranged at intervals. Specifically, the first mounting hole and / or the second mounting hole 1023 can be one or more rows of holes arranged at intervals in the second direction, and when it is necessary to adjust the position of the scraper 1022 on the support plate 1021, only need to correspond the second mounting hole 1023 on the scraper 1022 with a corresponding hole in the first mounting hole, and then lock it through a fastener (such as a bolt).

[0058] As shown in Figure 3 and Figure 4 , the copper bar chain cleaning system can also include a second driving mechanism 3 connected with the fixed part 101 of the cleaning module 1, for driving the cleaning module 1 to move in the second direction, so that each protrusion 10221 extends into its corresponding groove 2011 (as shown in Figure 7 ) or separates from the corresponding groove 2011, wherein the second direction is perpendicular to the extension direction of the copper bar chain 201.

[0059] Specifically, the second direction can be perpendicular to the first direction and the extension direction of the copper bar chain 201, respectively, such as the second direction being a vertical direction and the first direction being a horizontal direction perpendicular to the extension direction of the copper bar chain 201. At this time, the copper bar chain cleaning system can be arranged below the copper bar chain 201 of the tobacco cutting machine, and when the copper bar chain 201 is running, the copper bar chain cleaning system below it can have a certain distance from the copper bar chain 201, thereby not affecting the operation of the copper bar chain 201; and when the copper bar chain needs to be cleaned, the copper bar chain 201 stops running, and the cleaning part 102 is lifted by the second driving mechanism 3 so that the protrusions 10221 thereon can extend into the grooves 2011, and then the protrusions 10221 are driven by the cleaning driving part 103 to move repeatedly in the grooves 2011 to remove the accumulated soot and other substances in the grooves 2011. Optionally, the second driving mechanism 3 is a pneumatic cylinder, and the fixed part 101 of the cleaning module 1 is connected with the output end of the pneumatic cylinder.

[0060] Specifically, the second driving mechanism 3 can be used to drive the cleaning module 1 to move in the second direction between a third predetermined position and a fourth predetermined position, wherein when the cleaning module 1 is located at the third predetermined position, each protrusion 10221 is located directly below the corresponding groove 2011, and when the cleaning module 1 is located at the fourth predetermined position, each protrusion 10221 extends into the corresponding groove 2011.

[0061] In addition, the advantage of arranging the second driving mechanism 3 is that, when the protrusion 10221 finishes cleaning a certain section of the copper strip chain 201, the second driving mechanism 3 can drive the cleaning module 1 to move in the second direction so that the protrusion 10221 is separated from the groove 2011, thereby facilitating the movement of the copper strip chain 201 or the movement of the cleaning system.

[0062] For example, the driving module further comprises a third driving mechanism 2 connected with the cleaning module 1, which is used to adjust the relative position of the cleaning module 1 and the copper strip chain 201 in a third direction, so that each protrusion 10221 can be located directly below the corresponding groove 2011 (optionally, at this time, the cleaning module 1 is in a third preset position), and the third direction is parallel to the extension direction of the copper strip chain 201.

[0063] Specifically, the third driving mechanism 2 comprises a third driving part 21, a third sliding block 22 and a third sliding rail 23. The third sliding rail 23 extends along the third direction, the third sliding block 22 is slidably arranged on the third sliding rail 23, and the number of third sliding rails 23 is two, which are arranged at intervals along the first direction. Each third sliding rail 23 is slidably arranged with a third sliding block 22, and the third driving part 21 is arranged between the two third sliding rails 23. The fixed part 101 of the cleaning module 1 is fixedly installed on the upper end face of the third driving part 21 and the third sliding block 22, and the output end of the third driving part 21 is connected with the fixed part 101 of the cleaning module 1, so that the third driving part 21 can drive the fixed part 101 to move along the third direction.

[0064] Specifically, as shown in Figure 5 and Figure 3 The third driving part 21 can be a lead screw driving device, which comprises a lead screw 211, a lead screw driving motor 212 and a connecting part with a threaded sleeve arranged on the lead screw. The lead screw 211 is connected with the lead screw driving motor 212, the extension direction of the lead screw 211 is parallel to the extension direction of the copper strip chain 201, the entire cleaning module 1 is connected to the upper end face of the connecting part through the mounting plate 7, and the upper end face of the third sliding block 22 is also connected with the bottom end of the cleaning module 1. The lead screw driving motor 212 drives the lead screw 211 to rotate, so as to realize the movement of the connecting part, the third sliding block 22 connected with the connecting part and the cleaning mechanism along the extension direction of the copper strip chain 201, and to achieve the purpose of adjusting the position of the cleaning module 1 along the third direction on the supporting mechanism 6.

[0065] For example, the third driving part 21 is also electrically connected with the detection module 5, and the third driving part 21 can be used to drive the cleaning module 1 to move along the third direction so that each protrusion 10221 is located directly below each groove 2011 in the cleaning area according to the relative distance between the cleaning module 1 and the groove 2011 in the cleaning area detected by the detection module 5.

[0066] Exemplarily, the copper bus chain cleaning system can further comprise a first driving mechanism 4 connected with the cleaning module 1, the first driving mechanism 4 being configured to drive the cleaning module 1 to move between a first preset position and a second preset position in a first direction, wherein when the cleaning module 1 is located at the first preset position, each protrusion 10221 is located directly below the copper bus chain 201, and when the cleaning module 1 is located at the second preset position, the cleaning module 1 and the copper bus chain 201 are staggered with each other in the first direction. In this way, the cleaning system is further prevented from colliding with the copper bus chain 201.

[0067] Specifically, as shown in Figure 6 the first driving mechanism 4 comprises a first sliding rail 41 extending in the first direction and a first sliding block 42 sliding on the first sliding rail 41, and the upper end surface of the first sliding block 42 is connected with the cleaning part 102 through the bottom plate 104. The first sliding block 42 is connected with a first driving motor to drive the first sliding block 42 to slide along the first sliding rail 41.

[0068] Exemplarily, the copper bus chain cleaning system further comprises a control module 8, which is electrically connected with the detection module 5, the cleaning driving part 103, the second driving mechanism 3, the first driving mechanism 4 and the third driving mechanism 2 respectively.

[0069] In specific implementation, detection switches (such as photoelectric switches) can be arranged at the first preset position to the fourth preset position to detect whether the cleaning module 1 is moved to the position. When the cleaning module 1 is moved to the first preset position (or the second preset position, or the third preset position, or the fourth preset position), the corresponding detection switch is triggered to send a signal to the control module 8 to prompt the control module 8 to control the corresponding mechanism to operate.

[0070] Specifically, the operation method of the copper bus chain cleaning system can comprise the following steps:

[0071] The driving module drives the cleaning module 1 to move towards the cleaning area;

[0072] The detection module 5 detects that each protrusion 10221 on the cleaning module 1 extends into each groove 2011 located in the cleaning area (as shown in Figure 7 The control module 8 controls the cleaning driving part 103 to repeatedly drive each protrusion 10221 to move in its corresponding groove 2011 to clean each groove 2011 in the cleaning area;

[0073] After the protrusion 10221 moves in the groove 2011 for a first preset time, the cleaning driving part 103 stops repeatedly driving the protrusion 10221, and the control module 8 controls the driving module to drive the cleaning module 1 to move away from the cleaning area so that the protrusion 10221 is separated from its corresponding groove 2011;

[0074] The copper bar chain 201 starts to run and stops after running a set length, so that the uncleaned part 102 on the copper bar chain 201 (specifically, the next section of the copper bar chain connected to the section just cleaned) runs to the cleaning area, and the above three steps are repeated;

[0075] wherein the time interval between each two adjacent runs of the copper bar chain 201 is defined as a second preset time length, the distance between the two farthest protrusions 10221 is defined as a preset distance, the second preset time length is greater than or equal to the first preset time length, and the set length is less than or equal to the preset distance.

[0076] Specifically, as described above, the driving module includes a second driving mechanism 3. At this time, the driving module drives the cleaning module 1 to move towards the cleaning area, which specifically can include: the control module 8 controls the second driving mechanism 3 to drive the cleaning module 1 to move from the third preset position to the fourth preset position, so that each protrusion 10221 extends into each corresponding groove 2011 located in the cleaning area. The control module 8 controls the driving module to drive the cleaning module 1 to move away from the cleaning area in the third step, which specifically includes: the control module 8 controls the second driving mechanism 3 to drive the cleaning module 1 to move from the fourth preset position to the third preset position.

[0077] Illustratively, the detection module 5 can also be used to detect the cleaning degree of the surface of the copper bar chain groove 2011.

[0078] Specifically, the detection module 5 can be a visual recognition system, which includes a camera and can feed the collected images or videos to a display device in real time to facilitate personnel to watch and master the cleaning site situation. The visual recognition system includes an image acquisition terminal and a processing system, and the image acquisition terminal is composed of a camera, lighting and other components, and is installed on the rack of the automatic cleaning device in a static state. When installing, with the running direction of the copper bar chain as the reference, the image acquisition terminal is installed forward. Specifically, the visual recognition system can be used to detect the distance between the copper bar chain groove and the scraper, and the specific process is as follows: the visual recognition system performs optical processing on the working condition environment of the copper bar chain, first uses the camera to collect image information, compresses the collected information, and then feeds it to a learning subsystem composed of a neural network and a statistical method, and then the learning subsystem associates the collected image information with the actual position of the finger-shaped scraper to complete the autonomous positioning and cleaning function of the finger-shaped scraper. For example, a certain feature of a section of copper bar chain can be set as a calibration position, and by comparison, the offset distance of the subsequent chain section is obtained, and the control system controls the cleaning device finger-shaped scraper to move a corresponding distance.

[0079] Illustratively, the visual recognition system can also be used to detect the cleaning condition of the copper bar chain groove, and the detection process is as follows:

[0080] A visual recognition model database is constructed, and the cleaned copper chain is stored as a comparison picture in the database. The visual recognition system uses a digital industrial camera to continuously collect pictures after the cleaning process and compares them with the pictures in the database in real time. When all the collected pictures meet the cleaning requirements, the cleaning operation is stopped. Further, self-learning and deep learning techniques can be used to improve the recognition accuracy of the cleaning effect determination.

[0081] For example, the copper chain cleaning system further comprises an alarm device 7 electrically connected with the detection module 5. Specifically, when the detection module 5 detects cleaning abnormalities or the protrusions 10221 do not match the grooves 2011 in place, the alarm device can be warned to remind relevant personnel to implement manual intervention. Specifically, in the visual recognition system, the problem copper chain picture can also be stored in the database, and the pictures are collected in real time during the cleaning process to determine whether abnormal phenomena (such as copper chain cracks, deformation or hair clamps, etc.) occur, and then an abnormal signal is sent to the alarm device to issue an alarm.

[0082] Specifically, the control module 8 can be an industrial computer with a display screen, and the detection module 5 is electrically connected with the industrial computer. The detection module 5 can feed back the cleaning effect to the human-machine interface of the industrial computer in the form of images or videos in real time, which is convenient for managers to view in real time.

[0083] When the copper chain cleaning system works abnormally, the visual recognition system (i.e. the detection module 5) can feed back a signal to the alarm device 7 (such as an audible and visual alarm device) to alarm, and the control module controls the copper chain cleaning system and the wire cutting machine to stop running, waiting for the management personnel to handle.

[0084] The copper chain cleaning system provided by the application uses a power cleaning device to scrape and clean the residues in the grooves 2011 on the surface of the copper chain 201. The scraper 1022 adopts a finger plate form, which is convenient for cleaning the residues in the grooves 2011. During the cleaning process, since the length of the scraper 1022 on the cleaning part 102 is limited, each cleaning can only be performed on a section of the copper chain 201. Therefore, the copper chain 201 can be intermittently moved, and after the scraper 1022 cleans a section of the copper chain 201, the copper chain 201 moves a distance equal to the length of the scraper 1022. The relative distance between the grooves 2011 of the copper chain 201 and the scraper 1022 is detected by the detection module 5, and then the position of the protrusion 10221 on the scraper 1022 corresponds to the position of the groove 2011 of the copper chain 201 through the positioning and adjusting module. Then, the protrusion 10221 is extended into the groove 2011 on the surface of the copper chain 201 (as shown in Figure 2 The protrusion 10221 is repeatedly moved in the groove 2011 on the surface of the copper chain 201 through the cleaning driving part 103 to clean the residues in the groove 2011.

[0085] Correspondingly, the embodiments of the present application also provide a copper bar chain cleaning method, which is based on a copper bar chain cleaning system including a cleaning module 1 and a detection module 5, the cleaning module 1 includes a plurality of protrusions 10221 arranged in a straight line at intervals, and the cleaning method includes the following steps:

[0086] Step S101: The cleaning module 1 moves towards the cleaning area;

[0087] Step S102: When the detection module 5 detects that each protrusion 10221 on the cleaning module 1 extends into each groove 2011 located in the cleaning area, the control each protrusion 10221 repeatedly moves in its corresponding groove 2011 to clean each groove 2011 in the cleaning area;

[0088] Step S103: After the protrusion 10221 moves in the groove 2011 for a first preset time, the protrusion 10221 stops repeating movement, and the cleaning module 1 moves away from the cleaning area to make the protrusion 10221 separate from its corresponding groove 2011;

[0089] Step S104: The copper bar chain 201 starts running and stops after running a set length, so that the uncleaned part 102 of the copper bar chain 201 runs to the cleaning area, and the above steps S101 to S103 are repeated;

[0090] Wherein, the time interval between each adjacent two times of running of the copper bar chain 201 is defined as a second preset time, the distance between the two protrusions 10221 farthest apart is defined as a preset distance, the second preset time is greater than or equal to the first preset time, and the set length is less than or equal to the preset distance.

[0091] For example, step S101 specifically includes:

[0092] According to the relative distance between the cleaning module 1 and the groove 2011 in the cleaning area detected by the detection module 5, the cleaning module 1 is driven to move in the first direction so that each protrusion 10221 is located directly below each protrusion 10221 in the cleaning area;

[0093] The cleaning module 1 is driven to move in the second direction so that each protrusion 10221 extends into the corresponding groove 2011.

[0094] For example, the cleaning method further includes: collecting image information of the grooves 2011 of the copper bar chain 201 in the cleaning area and determining whether the grooves 2011 are clean according to the image information, if yes, the next step is executed; otherwise, a warning is issued.

[0095] The copper bar chain cleaning system and the cleaning method can clean the residues in the grooves 2011 of the copper bar chain 201 of the tobacco cutter in real time, avoid the feeding problem caused by the full grooves 2011 of the copper bar chain 201, ensure the cutting effect of the tobacco cutter and the quality of the tobacco, prolong the service life of the copper bar chain 201 of the tobacco factory, reduce the difficulty of manually cleaning and maintaining the copper bar chain 201, improve the production efficiency and benefits, provide necessary technical support and guarantee for the online cleaning and maintenance of the copper bar chain 201 of the tobacco cutter, and have strong popularization and application value.
