Description

Technical Field

[0001] The present invention relates to the technical field of cigarette production equipment, and in particular to a material blockage clearing system, cigarette wire feeding equipment and a material blockage clearing method. Background Art

[0002] In the cigarette production process, tobacco shreds need to be transported to the cigarette making machine through a tobacco feeder. The tobacco feeder distributes the tobacco shreds to the cigarette making machine through a negative pressure bellows. The tobacco feeder includes a feeding channel and a wire outlet channel. The wire outlet channel is mostly a funnel-shaped structure. The discharge port at the bottom of the feeding channel is smaller than the feeding port of the feeding channel. When the wind pressure in the wire outlet channel is too low or there is too much material, the feeding channel will be blocked. The existing solution is to set an alarm mechanism. When the feeding channel is blocked, an alarm is sounded and the operator manually unclogs the feeding channel. However, the efficiency of manual processing is slow, and there is a situation where the processing is not timely, resulting in reduced production efficiency. In addition, manual dredging also has the risk of operator hand injury, which poses a great safety hazard. Therefore, there is an urgent need for a blockage dredging system, a tobacco feeding device, and a blockage dredging method to solve the above problems. Summary of the Invention

The control device receives the detection data and analyzes the detection data. When the wind speed is greater than 0 and there is no material in the feed channel, it is judged that the feed channel can work normally. At this time, it is detected that the blockage height in the feed channel is greater than 0, and it is judged that there is a blockage in the feed channel. The control device controls the clearing device to clear the blockage. The blockage is stirred by the clearing telescopic rod, and the bottom blockage can fall into the feed channel. At this time, the feed channel works normally, and the cleared material can be conveyed to the cigarette making machine by the negative pressure wind. After the blockage in the feed channel is cleared, the wind speed detection mechanism detects that the wind speed is greater than 0, the material detection mechanism detects that there is material in the feed channel, and the light curtain detection mechanism does not detect the blockage.

[0047] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0048] like Figures 1 to 3 As shown, the wire feeder 1 includes a feed channel 11 and a wire outlet channel 12. The feed channel 11 is mostly a funnel-shaped structure. When the wind pressure in the wire outlet channel 12 is too low or there is too much material, the material fails to flow out of the wire outlet channel 12 in time, and is squeezed at the bottom of the feed channel 11 to form a blockage. Therefore, the present invention provides a wire feeding device, including a wire feeder 1 and a blockage clearing system installed on the wire feeder 1. The blockage clearing system is used to clear the blockage in the feed channel 11 of the wire feeder 1.

[0049] like Figures 1 to 3 As shown, the blockage clearing system includes a detection device, a clearing device 3 and a control device. The detection device includes a wind speed detection mechanism 21, a light curtain detection mechanism 22 and a material detection mechanism 23. The wind speed detection mechanism 21 is used to detect the wind speed in the wire outlet channel 12, the light curtain detection mechanism 22 is used to detect the blockage height of the discharge channel 11, and the material detection mechanism 23 is used to detect the material in the wire outlet channel 12.

[0050] Exemplarily, the wind speed detection mechanism 21 is disposed inside the wire outlet channel 12, and the wind speed detection mechanism 21 is connected to the inner side wall of the wire outlet channel 12. The wind speed detection mechanism 21 includes a wind speed detection head for collecting wind speed and a connecting base, and the connecting base is fixedly connected to the inner wall of the wire outlet channel 12 to prevent the wind speed detection mechanism 21 from affecting the outflow of materials in the wire outlet channel 12, causing material blockage in the wire outlet channel 12. In other embodiments, the wind speed detection mechanism 21 can also be penetrated through the side wall of the wire outlet channel 12, and the connecting base is fixedly connected to the outer wall of the wire outlet channel 12. At the same time, the wind speed detection head extends into the wire outlet channel 12, further reducing the space occupied by the wind speed detection mechanism 21 in the wire outlet channel 12.

[0051] Exemplarily, the light curtain detection mechanism 22 is arranged on both sides of the feeding channel 11 and extends in the vertical direction. The wire feeder 1 is provided with observation windows 14 on both sides of the feeding channel 11. The observation windows 14 are made of transparent or translucent materials. The observation windows 14 are used to observe the material situation in the feeding channel 11. The light curtain detection mechanism 22 is arranged on the outside of the observation window 14 and is connected to the feeding channel 11. The light curtain detection mechanism 22 includes a light curtain receiver and a light curtain transmitter. The light curtain receiver and the light curtain transmitter are symmetrically arranged on both sides of the observation window 14 and fit with the observation window 14. The light curtain receiver and the light curtain transmitter both extend in the vertical direction. The light curtain transmitter can transmit a light curtain toward the light curtain receiver. The light curtain receiver can receive the light curtain and generate a receiving signal. When there is material blockage in the feeding channel 11, the light curtain receiver and the light curtain transmitter are partially blocked, and the light curtain receiver can only receive part of the light curtain. The light curtain detection mechanism 22 obtains the height of the blockage in the feeding channel 11 by collecting the height of the light curtain blocked by the blockage. In other embodiments, the light curtain detection mechanism 22 is disposed on both sides of the material discharge channel 11 or is disposed inside the material discharge channel 11 .

[0052] Exemplarily, the material detection mechanism 23 is arranged at the intersection of the feed channel 11 and the wire outlet channel 12, and the material detection mechanism 23 is connected to the side wall of the wire outlet channel 12. The material detection mechanism 23 includes a light emitting element and a light receiving element. The light emitting element and the light receiving element are symmetrically arranged on both sides of the wire outlet channel 12. The light emitting element can emit light toward the light receiving element, and the light receiving element can receive the light and generate a receiving signal. When there is material in the wire outlet channel 12, the light is blocked and the light receiving element cannot receive the light, that is, when the light emitting element or the light receiving element is blocked, there is material in the wire outlet channel 12, and when the material detection element is not blocked, there is no material in the wire outlet channel 12. In other embodiments, the material detection mechanism 23 is provided with a camera to shoot the inside of the wire outlet channel 12 to further determine whether the material in the wire outlet channel 12 is a blockage.

[0053] like Figures 1 to 4As shown, the dredging device 3 includes a dredging telescopic rod 31, which can be extended and retracted in the vertical direction in the discharge channel 11. The blocked materials accumulated in the discharge channel 11 can fall into the wire outlet channel 12 under the telescopic stirring of the dredging telescopic rod 31, thereby achieving the purpose of dredging the blockage. Exemplarily, the dredging device 3 includes a shell 32 and a movable telescopic rod 33. The dredging telescopic rod 31 and the movable telescopic rod 33 are both arranged in the shell 32. The dredging telescopic rod 31 is connected to the shell 32 through the movable telescopic rod 33. The movable telescopic rod 33 can be extended and retracted in the horizontal direction. A support part 311 is provided at the bottom of the dredging telescopic rod 31. The support part 311 is slidably connected to the shell 32. When the movable telescopic rod 33 is extended and retracted in the horizontal direction, it can drive the dredging telescopic rod 31 to move in the same direction; at the same time, the shell 32 is provided with a quick-connect socket 321, and the quick-connect socket 321 can be inserted into the wire outlet channel 12, so that the inner cavity of the shell 32 is connected with the wire outlet channel 12, which facilitates the installation and disassembly of the dredging device 3.

[0054] The control device is connected to the detection device by signal, and the control device can receive data detected by the detection device. At the same time, the control device is connected to the dredging device 3 by signal. When the wind speed is greater than 0, the blockage height is greater than 0, and there is no material in the wire outlet channel 12, the control device controls the dredging device 3 to clear the blockage. Furthermore, the control device is provided with an alarm mechanism.

[0055] like Figure 5 As shown, in the actual working process, the steps of the blockage dredging method are as follows:

[0056] The detection device detects the wind speed in the wire outlet channel 12, the material in the wire outlet channel 12 and the blockage height of the discharge channel 11 and transmits the detection data to the control device. After receiving the detection data, the control device enters the judgment program:

[0057] When the wind speed in the wire outlet channel 12 is not greater than 0, that is, the wind speed detection mechanism 21 does not detect the wind pressure in the wire outlet channel 12, an abnormality occurs inside the wire outlet channel 12 and the material cannot flow. At this time, the control device sends an alarm signal, and the staff stops feeding the wire feeder 1 and shuts down the wire feeder 1. At the same time, the staff checks the abnormality inside the wire outlet channel 12 and handles the abnormality.

[0058] When the wind speed in the wire outlet channel 12 is greater than 0, there is no backlog of material in the wire outlet channel 12, and the blockage height of the discharge channel 11 is greater than 0, the wire outlet channel 12 is in a normal working state, and the material in the discharge channel 11 is blocked and forms a blockage. At this time, the control device starts the dredging device 3, and the dredging device 3 is switched to a working state. The telescopic rod 33 is moved to push the dredging telescopic rod 31 to move to the bottom of the discharge channel 11. The dredging telescopic rod 31 is extended and retracted in the vertical direction and continuously stirs the blocked material in the discharge channel 11 to dredge the discharge channel 11.

[0059] When the wind speed in the wire outlet channel 12 is greater than 0, there is no backlog of material in the wire outlet channel 12, and the blockage height of the discharge channel 11 is not greater than 0, the wire outlet channel 12 and the discharge channel 11 are both in normal working state, the control device controls the dredging device 3 to switch to the standby state, the dredging telescopic rod 31 retracts, and the moving telescopic rod 33 drives the dredging telescopic rod 31 to retract into the housing 32;

[0060] When the wind speed in the wire outlet channel 12 is greater than 0, but accumulated material is detected in the wire outlet channel 12, the wire outlet channel 12 below the feed channel 11 is blocked, and the wire outlet channel 12 cannot work normally. Even if the dredging device 3 dredges the blocked material in the feed channel 11, the blocked material cannot flow to or out of the wire outlet channel 12. At this time, the control device sends an alarm signal, and the staff shuts down the wire feeder 1 and clears the blockage in the wire outlet channel 12.

[0061] Since the detection device can detect the blockage of the feeding channel 11 in real time and clear the blockage in the feeding channel 11 in time, it can greatly avoid the blockage of the wire outlet channel 12, and at the same time avoid the accumulation of a large amount of blockage, which increases the difficulty of clearing, further reduces manual intervention and improves production efficiency.

[0062] For example, the control device can control the telescopic frequency of the dredging telescopic rod 31, and the telescopic frequency of the dredging telescopic rod 31 is obtained by the following formula:

[0063] f=A+K*H*V, where f is the telescopic frequency of the telescopic rod 31 for dredging, A is the minimum value of f, K is the preset value, H is the blockage height of the feeding channel 11, and V is the wind speed in the wire outlet channel 12. The telescopic frequency of the telescopic rod 31 for dredging is directly proportional to the wind speed in the wire outlet channel 12 and the blockage height of the feeding channel 11, respectively. When the wind speed in the wire outlet channel 12 is greater, the flow speed of the material in the wire outlet channel 12 is faster, the telescopic frequency of the telescopic rod 31 for dredging is higher, and the dredging efficiency is also higher. The blocked material can flow quickly to the wire outlet channel 12, thereby improving production efficiency. The higher the blockage height of the feeding channel 11 is, the more difficult it is to dredge it, that is, the telescopic rod 31 needs a higher telescopic frequency to dredge the feeding channel 11.

[0064] The preset value is set according to the actual working conditions. The preset value can be 0.04~0.0.6Hz*s / m 2 Any value in, preferably, the preset value is set to 0.05Hz*s / m 2 Similarly, the minimum value of the telescopic frequency of the telescopic rod 31 for dredging is set according to the minimum frequency of dredging the discharge channel 11. The minimum value of the telescopic frequency of the telescopic rod 31 for dredging can be any fixed value between 0.4 and 0.8 Hz. Preferably, the minimum value of the telescopic frequency of the telescopic rod 31 for dredging is 0.5 Hz.

[0065] The higher the extension and retraction frequency of the telescopic rod 31 for dredging, the higher the dredging efficiency. However, in the actual production process, when the extension and retraction frequency of the telescopic rod 31 for dredging is too high, the material will be excessively pounded, resulting in material crushing, affecting product quality. The extension and retraction frequency of the telescopic rod 31 for dredging is adjusted by the control device. While meeting the dredging efficiency and achieving the dredging purpose, the telescopic rod 31 is prevented from excessively pounding the material, causing material crushing, thereby improving product quality.

[0066] In this embodiment, the tobacco feeder 1 is mainly used for the transmission of tobacco. Since the types of tobacco are different, the hardness of tobacco is also different. The type of tobacco is determined by its brand. The hardness of tobacco of each brand can be detected in advance and a corresponding database can be established. The staff can determine the hardness of tobacco by the brand of tobacco. Tobacco also contains stems and flakes. The more stems and flakes contained in the tobacco, the higher the hardness of the tobacco, and the more difficult it is to clear the blockage formed by it. It is necessary to increase the extension and retraction frequency of the telescopic rod 31 for clearing. The content of stems and flakes in high-quality tobacco is extremely low, and the hardness of the tobacco is even lower. The blockage formed by it is not difficult to clear. The extension and retraction frequency of the telescopic rod 31 for clearing should be reduced to avoid tobacco breakage. For this reason, the blockage clearing system is also provided with a brand control mechanism. The brand control mechanism is connected to the control device signal. The brand control mechanism is used to input the brand coefficient. The extension and retraction frequency of the telescopic rod 31 for clearing is obtained by the following formula:

[0067] f = A + K*H*V*B, where B is the grade coefficient. The grade coefficient is determined based on the hardness of the material. Materials with higher hardness have higher grade coefficients, while materials with lower hardness have lower grade coefficients. For example, the grade coefficients include a low-range coefficient, a mid-range coefficient, and a high-range coefficient. The low-range coefficient is set to 0.8, the mid-range coefficient is set to 1, and the high-range coefficient is set to 1.2.

[0068] like Figure 2 As shown, the card classification control mechanism includes a low-gear control button 41, a mid-gear control button 42 and a high-gear control button 43. The low-gear control button 41, the mid-gear control button 42 and the high-gear control button 43 are installed on the outer end of the shell 32 and are respectively connected to the control device signal. The low-gear control button 41 corresponds to the input of the low-gear coefficient, the mid-gear control button 42 corresponds to the input of the mid-gear coefficient, and the high-gear control button 43 corresponds to the input of the high-gear coefficient.

[0069] During actual operation, the staff installed the blockage clearing system on the wire feeder 1, and the clearing device 3 was connected to the wire outlet channel 12 through the quick-connect socket 321. The preset value and the minimum value of the telescopic frequency of the clearing telescopic rod 31 were input into the control device. The brand coefficient was selected according to the material model, and the corresponding control button was pressed to start the blockage clearing system to automatically clear the blockage in the discharge channel 12. It is easy to operate and can effectively improve production efficiency and reduce safety hazards.
