Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing and detection, and more specifically, to a tobacco material foreign body removal device based on visual imaging technology. Background Art

[0002] When the tobacco thread throwing machine used in the tobacco thread making workshop is in operation, its thread throwing pipe transports the finished tobacco thread from the thread storage room in the thread making workshop to the cigarette rolling machine in the rolling workshop through a large negative pressure. The tobacco thread is then cooled from drying to blending and flavoring before entering the thread storage room.

[0003] At present, most belt conveyors are equipped with plastic skirts and each drop port uses plastic skirts. Due to friction and aging, the plastic skirts may break and fall off, and enter the hopper with the tobacco / stem. In addition, before the finished tobacco enters the hopper, cleaning tools such as towels and mops used for equipment maintenance in the previous process may be accidentally forgotten in the drum during maintenance, or accidentally fall into the tobacco material on the belt conveyor / vibrating conveyor and be covered and difficult to find, and enter the hopper with the finished tobacco.

[0004] The "debris" mentioned above will be sucked away along with the finished tobacco by the strong negative pressure in the pipe of the tobacco throwing machine and transported to the cigarette rolling machine, causing the cigarette rolling machine to stop, thereby causing an accident in the production process, affecting production efficiency, and may even damage the cigarette machine equipment; secondly, if there are larger "debris", a large amount of tobacco will be wrapped around, and there is a risk of blocking the pipe at the curved bend in the wire feeding pipe, which will cause a "broken wire" process quality accident.

[0027] Various exemplary embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present utility model.

[0028] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present utility model or its application or use.

[0029] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the specification.

[0030] In all examples shown and discussed herein, any specific values should be construed as merely exemplary and not as limitations. Thus, other examples of the exemplary embodiments may have different values.

[0031] As Figures 1 to 4 shown, an embodiment of the present utility model provides a foreign object removal device for cut tobacco materials based on vision imaging technology, including: a belt conveyor 1, a vibrating conveyor 2, a controller 3, and an image acquisition component 4.

[0032] The vibrating conveyor 2 is located below the belt conveyor 1. The belt conveyor 1 is used to convey cut tobacco materials onto the vibrating conveyor 2. An opening 21 is provided on the vibrating conveyor 2, and a sealing plate 5 is arranged to rotate along one side of the opening 21. Specifically, at least a part of the orthographic projection of the belt conveyor 1 coincides with the vibrating conveyor 2. The image acquisition component 4 is arranged between the outlet end of the belt conveyor 1 and the opening 21, and the image acquisition component 4 is used to photograph the cut tobacco between the inlet end of the vibrating conveyor 2 and the opening 21.

[0033] The image acquisition component 4 includes a first camera 41 and a second camera 42. The first camera 41 and the second camera 42 are sequentially arranged between the inlet end of the cut tobacco of the belt conveyor 1 and the opening 21. Both the first camera 41 and the second camera 42 are electrically connected to the controller 3. Both the first camera 41 and the second camera 42 are used to take pictures of the cut tobacco in the vibrating conveyor 2 to form picture information and transmit the picture information to the controller 3.

[0034] The controller 3 is connected to the sealing plate 5, and the controller 3 is used to control the sealing plate 5 to close or open the opening 21.

[0035] Specifically, the first camera 41 and the second camera 42 sequentially photograph the cut tobacco on the vibrating conveyor 2, and the first camera 41 is located upstream of the second camera.

[0036] The first camera 41 is tilted and faces the junction of the belt conveyor 1 and the vibrating conveyor 2 . The first camera 41 shoots the tobacco shreds falling from the belt conveyor 1 to the vibrating conveyor 2 .

[0037] The first camera 41 directly captures foreign objects during the falling process of the tobacco material. The first camera 41 captures foreign objects that may be wrapped in the tobacco. The vibration of the vibrating conveyor 2 will cause the tobacco balls to be shaken apart, thereby making the foreign objects appear in the visible range of the first camera 41 and be captured.

[0038] When working, the first camera 41 and the second camera 42 take pictures of the tobacco in real time, and transmit the first picture information and the second picture information obtained to the controller 3. When the controller 3 determines that there are foreign objects in the tobacco according to the first picture information and the second picture information, the controller 3 controls the sealing plate 5 to open the opening 21, and then the foreign objects are discharged through the opening 21.

[0039] The utility model places the vibrating conveyor 2 below the belt conveyor 1, and sets an opening 21 on the vibrating conveyor 2 and a sealing plate 5 rotating along one side of the opening 21 on the opening 21; the first camera 41 and the second camera 42 are sequentially set between the inlet end of the belt conveyor 1 and the opening 21, and the first camera 41 and the second camera 42 are both electrically connected to the controller 3, and the controller 3 is connected to the sealing plate 5. When working, the first camera 41 and the second camera 42 take pictures of the tobacco in real time, and transmit the first picture information and the second picture information obtained by the shooting to the controller 3. When the controller 3 determines that there are foreign objects in the tobacco according to the first picture information and the second picture information, the controller 3 controls the sealing plate 5 to open the opening 21, and then the foreign objects are discharged through the opening 21, thereby avoiding the problem that the foreign objects get stuck in the cigarette making equipment or block the cigarette making equipment, causing the equipment to stop, effectively improving the work efficiency, and reducing the failure rate of the cigarette making equipment and the labor intensity of the maintenance personnel.

[0040] In one embodiment of the tobacco material foreign body removal device based on visual imaging technology of the utility model, as Figures 1 to 4 As shown, the tobacco material foreign body removal device based on visual imaging technology also includes a central control system 6, which is respectively connected to the controller 3, the first camera 41 and the second camera 42. The central control system 6 is used to receive image information and transmit work information to the controller 3 according to the image information.

[0041] Specifically, after the central control system 6 receives the picture information, it performs an algorithm analysis on the picture information to determine whether there are foreign objects in the tobacco.

[0042] The central control system 6 stores preset picture information, which is picture information of finished cut tobacco data and foreign object picture information, and can establish a complete database based on the picture information uploaded by the first camera 41 and the second camera 42, and pre-enter the photo data of common possible "foreign objects" into the system database.

[0043] The algorithm analysis of the central control system 6 for the picture information is as follows: taking the preset picture information as a reference object, comparing the picture information with the preset picture information precisely and quickly. When the central control system 6 identifies that the picture information is the same as the foreign object picture information, it can respond quickly without excessive algorithm analysis. At the same time, for the foreign object picture information not entered into the system detected by the central control system 6, the central control system 6 automatically enters it into the database after completing a rejection alarm execution program loop, further improving the sensitivity and accuracy of the present utility model.

[0044] First, the first camera 41 takes pictures of the falling cut tobacco to obtain the first picture information, and transmits the first picture information to the central control system 6. The central control system 6 performs algorithm analysis on the first picture information and compares the first picture information with the preset picture information. When the central control system 6 determines that the cut tobacco in the first picture information has a foreign object, the central control system 6 issues an alarm, and after a time T1, transmits the working information of opening the opening 21 to the controller 3, and the controller 3 controls the sealing plate 5 to move to open the opening 21. If the central control system 6 determines that the cut tobacco in the first picture information does not have a foreign object, the central control system 6 does not control the opening 21 to open.

[0045] The second camera 42 takes pictures of the cut tobacco on the vibrating conveyor 2 to obtain the second picture information, and transmits the second picture information to the central control system 6. The central control system 6 performs algorithm analysis on the second picture information and compares the second picture information with the preset picture information. When the central control system 6 determines that the cut tobacco in the second picture information has a foreign object, the central control system 6 transmits the working information of opening the opening 21 to the controller 3 after a time T2 (T2 < T1), and the controller 3 controls the sealing plate 5 to move to open the opening 21. If the central control system 6 determines that the cut tobacco in the second picture information does not have a foreign object, the central control system 6 does not control the opening 21 to open.

[0046] Further, the foreign object rejection device for cut tobacco materials based on visual imaging technology of the present utility model further includes an alarm, and the alarm is electrically connected to the central control system 6. When the central control system 6 determines that there is a foreign object in the cut tobacco, the central control system 6 controls the alarm to issue an alarm to remind the staff.

[0047] In an implementation manner of the foreign object rejection device for cut tobacco materials based on visual imaging technology of the present utility model, as Figure 1As shown, the image acquisition component 4 further includes a third camera 43, which is arranged between the second camera 42 and the opening 21. Specifically, the third camera 43 is also electrically connected to the central control system 6. The third camera 43 is located on one side of the opening 21, close to the opening 21, and the third camera 43 is located downstream of the second camera 42.

[0048] The third camera 43 continuously acquires the situation of the cut tobacco material in the front section of the opening 21 to obtain third picture information, and transmits the third picture information to the central control system 6. The central control system 6 performs algorithm analysis on the third picture information, and compares the third picture information with the preset picture information. When the central control system 6 determines that there is no foreign object in the cut tobacco in the third picture information and the opening time of the opening 21 is greater than T3, the central control system 6 sends the information of closing the opening 21 and eliminating the alarm information to the controller 3, and the controller 3 drives the sealing plate 5 to close the opening 21 and controls the alarm to stop working.

[0049] When the central control system 6 determines that there is a foreign object in the cut tobacco in the third picture information or the opening time of the opening 21 is less than T3, the central control system 6 sends the information of opening the opening 21 and sending out an alarm information to the controller 3, and the controller 3 keeps the opening 21 in an open state and makes the alarm work continuously.

[0050] Through the real-time online data acquisition of multiple high-definition and high-speed cameras and the rapid response and comprehensive collaborative operation of the central control system 6 of the present utility model, the foreign object removal alarm can be realized.

[0051] The present utility model can effectively prevent foreign objects from entering the throwing machine along with the finished cut tobacco due to various unforeseeable factors before the finished cut tobacco enters the throwing machine, resulting in the shutdown and material breakage of the cigarette making and tipping machine, even damage to the cigarette machine equipment and blockage of the throwing pipeline, thus affecting the production quality and efficiency. It can greatly guarantee the production process quality and production efficiency and reduce the production safety risk.

[0052] In addition, the present utility model is easy to install, does not damage the equipment, has low requirements for the performance of the hardware equipment, adapts to the needs of multiple scenarios, and does not need to be disassembled when maintaining the equipment.

[0053] It should be noted that the foreign object removal device for cut tobacco material based on the vision imaging technology of the present utility model can also be installed on the throwing machine to meet the on-site installation conditions, remedy the possible missed removal situation in the previous process, install a high-definition and high-speed camera at the cut tobacco material inlet of the cut tobacco conveying pipeline of the throwing machine, and install an electric valve on the upper section of the throwing pipeline according to the actual situation. When a missed removed foreign object is detected, the valve acts to remove the material to the corresponding receiving device, playing a bottom-line role and further improving the reliability of the present utility model.
