Description

TECHNICAL FIELD

[0001] The present application relates to the field of tobacco leaf feeding, and more particularly, to a hanging and removing identification system and method for a tobacco basket identification board. BACKGROUND

[0002] The tobacco leaf feeding section is the first process in the production of a tobacco processing line, which includes processes such as unpacking, unboxing, slicing, tobacco basket loading, and box turning.

[0003] In the tobacco basket loading process, tobacco leaves are loaded into a tobacco basket, and the tobacco basket loaded with the tobacco leaves is transported to the box turning process along a conveying belt. The same batch of tobacco leaves is usually loaded into multiple tobacco baskets, and the multiple tobacco baskets are transported to the box turning process one after another. In actual production, the tobacco basket loading process is far away from the box turning process. The workers at the box turning process cannot identify which batch of tobacco leaves is in the tobacco basket. In order to solve this problem, the first tobacco basket of the same batch of tobacco leaves is hung with a "batch start" identification board in the tobacco basket loading process, and the last tobacco basket of the same batch of tobacco leaves is hung with a "batch end" identification board. In this way, the workers at the box turning process can know that a batch of tobacco leaves is being transported when they see the "batch start" identification board. When they see the "batch end" identification board, they can know that the batch of tobacco leaves has been transported. Before the tobacco basket enters the box turning process, the identification board needs to be removed to prevent the identification board from being mixed into the tobacco leaves.

[0004] In the prior art, it is usually relied on manual observation to determine whether it is the first or last tobacco basket of the same batch. If it is the first or last tobacco basket of the same batch, the identification board needs to be hung. Before entering the box turning process, the identification board on the first and last tobacco baskets also needs to be manually observed and removed. However, in actual operation, the workers are prone to forget to hang or remove the identification board, resulting in production errors and quality problems.

[0005] Therefore, how to accurately hang and remove the identification board to avoid production errors and ensure production quality is a key problem that needs to be solved by those skilled in the art. SUMMARY

Detailed Implementation

[0054] The core of this invention is to provide a system for identifying the hanging and unhanging of tobacco basket labels, thereby avoiding production errors and ensuring production quality.

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] This invention discloses a label identification system for tobacco baskets, which includes: a first controller, a tobacco leaf detector, a first alarm 4, a first label detector, and a first reset button.

[0057] The tobacco leaf detector, the first alarm 4, the first identification tag detector, and the first reset button are all communicatively connected to the first controller. The tobacco leaf detector is used to detect whether there are tobacco leaves on the conveyor belt upstream of the loading platform. The first controller determines whether the tobacco basket below the loading platform 1 is the first or the last tobacco basket based on the detection result of the tobacco leaf detector. If the first controller determines that the tobacco basket below the loading platform 1 is the first or the last tobacco basket, the first controller controls the first alarm 4 to sound an alarm to prompt the operator to tag the first or last tobacco basket. The first alarm 4 is preferably an audible and visual alarm.

[0058] Upon receiving the alarm, the operator hangs a sign 3 on either the first or last tobacco basket. For the first basket, a "Batch Begins" sign 3 is hung. For the last basket, a "Batch Ends" sign 3 is hung. After hanging the sign 3, the first sign detector detects it and generates a first sign signal, which is then sent to the first controller. Following the sign hanging, the operator presses the first reset button, which generates a first reset signal, which is also sent to the first controller. Upon receiving both the first sign signal and the first reset signal, the first controller then stops the first alarm 4.

[0059] In this invention, the first controller receives the first sign signal and the first reset signal in sequence before controlling the first alarm 4 to stop the alarm. That is, the first sign detector and the first reset button are both indispensable.

[0060] If only the first sign detector is set up, and the first controller stops the first alarm 4 after receiving the first sign signal, the following situation may occur: the first sign detector is interfered with by surrounding components and mistakenly generates the first sign signal, thereby causing the first alarm 4 to stop alarming. At this time, the operator will mistakenly believe that the sign 3 has been hung.

[0061] If only a first reset button is provided, the operator will press it after hanging the sign 3 on the edge of the first or last tobacco basket, thus stopping the first alarm 4. However, since the tobacco baskets are located below the loading platform 1, the operator cannot directly observe the sign 3 on the first or last tobacco basket. Therefore, the following situations may occur: the operator presses the reset button without actually hanging the sign 3; or the sign 3 falls accidentally after being hung; or the operator presses the first reset button by mistake and forgets to hang the sign 3 without any alarm prompt.

[0062] In this invention, after the sign 3 is manually hung, the first sign detector detects the sign 3, proving that the sign 3 has indeed been hung and is in place. At this time, the alarm is still in the alarm state. Under the alarm prompt, the operator will confirm whether the sign has been hung, and after confirmation, manually press the first reset button to stop the alarm.

[0063] The tobacco basket identification system of this invention can not only promptly remind operators to attach tags to the first or last tobacco basket of the same batch, but also ensure the accuracy of tagging, thereby avoiding production errors and ensuring production quality.

[0064] In the tobacco basket loading process, the tobacco basket is located below the loading platform 1, and the inner cavity of the loading platform 1 is connected to the tobacco basket. Tobacco leaves on the loading platform 1 fall into the tobacco basket. To prevent the tobacco leaves from leaking out of the gap between the loading platform 1 and the tobacco basket during the falling process, those skilled in the art typically install a barrier around the loading platform 1, and this barrier is liftable. After the tobacco basket enters below the loading platform 1, the barrier descends, sealing the gap between the loading platform 1 and the tobacco basket. Typically, barriers are installed around three sides of the loading platform 1, while the fourth side, which connects to the upstream conveyor belt, is not equipped with a barrier. The tobacco basket gradually moves to the bottom of the loading platform 1 along a direction perpendicular to the fourth side. The tobacco basket stops moving when it reaches a position close to the fourth side of the loading platform 1. Therefore, the bottom surface of the loading platform 1 can be designed to bulge downwards near the fourth side to reduce the gap between the loading platform 1 and the tobacco basket. The loading platform 1 is sealed off from three sides of the tobacco basket by barriers, and the gap between the loading platform 1 and the fourth side of the tobacco basket is small enough to effectively prevent tobacco leakage.

[0065] The sign 3 is suspended on the fourth side of the tobacco basket, near the loading platform 1. Because the bottom surface of the loading platform 1 protrudes downwards near the fourth side, the distance between the sign 3 and the loading platform 1 is relatively small.

[0066] If a photoelectric detector is installed on the bottom surface of the loading platform 1, near the fourth side, the detector's beam will shine vertically downwards. The photoelectric detector will detect most objects. If falling tobacco leaves enter the detector's detection area, it will cause a false signal. Similarly, if a person's hand enters the detector during the labeling process, it will also cause a false signal. Therefore, it is impossible to accurately detect whether a label 3 is hanging on the tobacco basket.

[0067] If a photoelectric detector is installed around the loading platform 1 and the light from the photoelectric detector shines horizontally, the light from the photoelectric detector will be blocked by the surrounding equipment such as barriers, causing the photoelectric detector to generate a false signal.

[0068] To avoid the aforementioned problems, the present invention preferably uses a proximity switch 7 as the first sign detector. The proximity switch 7 only senses metal, thus avoiding the generation of false signals. However, the detection distance of the proximity switch 7 is very short. If the height of the tobacco basket deviates and becomes lower, the proximity switch 7 may not detect the sign 3 after it is hung on the tobacco basket. To solve this problem, the present invention designs the sign 3 with a structure that is easy to hang and remove. When the proximity switch 7 cannot detect the sign 3, the sign 3 can be manually held and brought close to the proximity switch 7 above. After the proximity switch 7 detects the sign 3, the sign 3 can then be hung on the tobacco basket.

[0069] The sign 3 specifically includes a body plate 31, an inner side plate 32, and an outer side plate 33. The two sides of the body plate 31 are connected to the inner side plate 32 and the outer side plate 33, respectively. When hanging the sign 3, the lower surface of the body plate 31 only needs to be in contact with the upper surface of the tobacco basket, with the inner side plate 32 located inside the tobacco basket and the outer side plate 33 located outside the tobacco basket. The upper surface 311 of the body plate 31 is used to trigger the proximity switch 7 to generate a first sign signal.

[0070] When hanging the sign 3, it is necessary to ensure that the sign 3 is hung within the detection area of ​​the proximity switch 7. To this end, an infrared emitter is installed on the bottom surface of the loading platform 1. The infrared emitter illuminates a light spot on the upper surface of the tobacco basket used for hanging the sign 3, and this light spot is located within the detection area of ​​the proximity switch 7. The sign 3 can be manually placed within the area formed by the light spot.

[0071] In this invention, the tobacco leaf detector is preferably a first photoelectric switch. The first photoelectric switch is located on the side of the conveyor belt upstream of the loading platform 1. If tobacco leaves pass by, the first photoelectric switch is triggered to generate a signal indicating the presence of tobacco leaves. If no tobacco leaves pass by, the first photoelectric switch generates a signal indicating the absence of tobacco leaves.

[0072] The input end of the conveyor belt upstream of loading platform 1 is connected to the tobacco bale conveyor 6. The tobacco bale conveyor 6 transports tobacco bales to the conveyor belt upstream of loading platform 1. After being sliced ​​and loosened, the tobacco bales are conveyed to loading platform 1. The tobacco bale conveyor 6 is controlled by a start button. The start button is communicatively connected to the first controller. After the start button is pressed, the tobacco bale conveyor 6 begins operation, and simultaneously, the start button sends a start signal to the first controller. If the first controller receives the start signal from the start button and simultaneously receives a no-tobacco-leaf signal from the first photoelectric switch, it indicates that the tobacco bale conveyor 6 is about to transport a new batch of tobacco leaves to loading platform 1. At this time, the tobacco basket located below loading platform 1 is the first tobacco basket. Therefore, the first controller controls the first alarm 4 to sound an alarm, prompting the operator to hang the "Batch Start" sign 3.

[0073] To improve the accuracy of the first photoelectric switch detection and avoid generating false signals, this invention sets multiple first photoelectric switches at intervals along the conveyor belt upstream of the loading platform 1. If all the first photoelectric switches send a no-tobacco-leaf signal to the first controller, it indicates that there are indeed no tobacco leaves on the conveyor belt. In this case, if the first controller also receives a start signal from the start button, it will determine that the tobacco basket below the loading platform 1 is the first tobacco basket. If several or one of the multiple first photoelectric switches do not send a no-tobacco-leaf signal to the first controller, it indicates that the previous batch of tobacco leaves has not been completely conveyed, and the tobacco basket below the loading platform 1 is not the first tobacco basket.

[0074] If all the first photoelectric switches initially send a signal indicating the presence of tobacco leaves to the first controller, and then, along the tobacco leaf conveying direction, each first photoelectric switch sequentially sends a signal indicating the absence of tobacco leaves to the first controller, it indicates that the conveying of this batch of tobacco leaves is complete. After receiving all the signals indicating the absence of tobacco leaves from the first photoelectric switches, the first controller determines that the tobacco basket below the loading platform 1 is the last tobacco basket. The first controller then activates the first alarm 4 to alert the operators to hang the "Batch Completed" sign 3.

[0075] The present invention also discloses a tobacco basket identification system for removing tobacco basket signs, the system comprising a second controller, a bracket 9, a second sign detector, a second alarm 8, and a second reset button.

[0076] After the tobacco basket loading process is completed, the tobacco baskets are conveyed to the tipper 10 by the conveyor belt upstream of the tipper 10. Before entering the tipper 10, the identification tags 3 hanging on the tobacco baskets need to be removed. A bracket 9 is located beside the conveyor belt upstream of the tipper 10, and a second identification tag detector is mounted on the bracket 9. A preset distance exists between the bracket 9 and the tipper 10 to ensure that operators have sufficient time to remove the tags before the tobacco baskets enter the tipper 10. The second identification tag detector detects passing tobacco baskets. If an identification tag 3 is detected on a tobacco basket, the second identification tag detector sends a second tag presence signal to the second controller. Upon receiving the second tag presence signal, the second controller activates the second alarm 8 to alert the operator to remove the tag. After removing the tag, the operator manually presses the second reset button, which generates a second reset signal. Upon receiving the second reset signal, the second controller activates the second alarm 8 to stop the alarm.

[0077] In this invention, whether it's the "Batch Start" sign 3 or the "Batch End" sign 3, as long as sign 3 passes the second sign detector, the second alarm 8 will be triggered. Upon receiving the alarm signal, the operator will remove sign 3. This solves the problem of operators forgetting to remove the signs.

[0078] Since the tobacco basket is not obstructed by other equipment when it moves close to the tipper 10, the operator can directly observe whether the identification tag 3 is hanging on the tobacco basket. Therefore, before pressing the second reset button, the operator can directly observe and confirm whether the tag has been removed. After confirming that the tag has been removed, the operator manually presses the second reset button to stop the alarm of the second alarm 8.

[0079] If the second sign detector is designed as a proximity switch, its detection distance is relatively short. Therefore, the second sign detector needs to be positioned very close to the cigarette basket. If the second sign detector is placed above the cigarette basket, and the cigarette basket is too tall, it will touch the detector when passing it. If the cigarette basket is too short, the sign will move out of the detector's detection range. If the second sign detector is placed beside the cigarette basket, and the cigarette basket is too long, it will also touch the detector when passing it.

[0080] Therefore, the present invention designs the second sign detector as a second photoelectric switch 11. The photoelectric switch has a large detection range, and the second photoelectric switch 11 can be designed far enough away from the tobacco basket to prevent the tobacco basket from touching the second photoelectric switch 11 when passing by. Specifically, the second photoelectric switch 11 is located to the side of the tobacco basket, and the second photoelectric switch 11 emits horizontal light.

[0081] The sign 3 includes a web 31, an inner side plate 32, and an outer side plate 33. The inner side plate 32 and the outer side plate 33 are connected to the two sides of the web 31, respectively. The lower surface of the web 31 can be attached to the upper surface of the tobacco basket. The inner side plate 32 is located inside the tobacco basket, and the outer side plate 33 is located outside the tobacco basket. The side end face 312 of one side of the web 31 is used to trigger the second photoelectric switch 11, causing the second photoelectric switch 11 to generate a second sign signal. The vertical dimension of the side end face 312 of the web 31 is a preset dimension, that is, the thickness of the web 31 is a preset thickness, to facilitate detection by the second photoelectric switch 11.

[0082] This invention also provides a method for identifying tobacco basket labels, comprising:

[0083] S1: The first controller determines whether the tobacco basket below the loading platform 1 is the first tobacco basket or the last tobacco basket. If so, proceed to step S2.

[0084] S2: The first controller controls the first alarm device 4 to sound an alarm.

[0085] S3: The sign 3 is manually hung on the edge of the first or last tobacco basket, and the first sign detector is ensured to detect the sign 3. The first sign detector generates a first sign signal and sends the first sign signal to the first controller.

[0086] S4: When the first reset button is pressed manually, the first reset button generates a first reset signal. After receiving the first license plate signal and the first reset signal, the first controller controls the first alarm 4 to stop alarming.

[0087] In this method, when the first controller detects that the tobacco basket below the loading platform 1 is either the first or the last tobacco basket, the first controller activates the first alarm 4 to remind the operator to hang the tag, thus solving the problem of forgetting to hang the tag. The first alarm 4 only stops ringing after the first controller receives both a first tag signal and a first reset signal, thereby improving the accuracy of tag hanging.

[0088] The specific determination method for the first controller in step S1 is as follows:

[0089] If the first controller receives the start signal from the start button and the no-tobacco-leaf signals from all the first photoelectric switches, then the first controller determines that the tobacco basket below the loading platform 1 is the first tobacco basket. The start button controls the start and stop of the tobacco bale conveyor 6, which conveys tobacco bales to the conveyor belt upstream of the loading platform 1. If the start button is pressed and the first photoelectric switches do not detect tobacco leaves, it indicates that the previous batch of tobacco leaves has been conveyed and a new batch is about to be conveyed to the loading platform 1. Therefore, the tobacco basket below the loading platform 1 at this time is the first tobacco basket.

[0090] If the first controller receives no-smoke signals from each of the first photoelectric switches in sequence, then the first controller determines that the tobacco basket below the loading platform 1 is the last tobacco basket. Along the tobacco conveying direction, each of the first photoelectric switches sequentially sends a no-smoke signal to the first controller, indicating that the batch of tobacco has been transported. The last first photoelectric switch is closest to the loading platform 1. When the last first photoelectric switch sends a no-smoke signal to the first controller, the first controller activates the first alarm 4 to sound, indicating that the tobacco basket below the loading platform 1 is the last tobacco basket.

[0091] This invention also discloses a method for identifying cigarette basket labels by removing them, comprising:

[0092] T1: The second photoelectric switch 11 detects whether there is an identification sign 3 hanging on the cigarette basket that has passed through the second photoelectric switch 11. If so, proceed to step T2.

[0093] T2: The second photoelectric switch 11 generates a second license plate signal and sends the second license plate signal to the second controller.

[0094] T3: After receiving the second license plate signal, the second controller controls the second alarm device 8 to sound an alarm.

[0095] T4: Manually remove sign 3 and press the second reset button. The second reset button generates a second reset signal. After the second controller receives the second reset signal, it controls the second alarm 8 to stop alarming.

After the first controller receives the no-smoke signal sent by all the first photoelectric switches and receives the start signal of the start button, the first controller determines that the tobacco basket below the loading platform (1) is the first tobacco basket. After the first controller receives the smokeless signal from each of the first photoelectric switches in sequence, the first controller determines that the smoke frame below the loading platform (1) is the last smoke basket.

2. The tagging and identification system for tobacco basket identification signs according to claim 1, characterized in that, The first sign detector is a proximity switch (7), which is disposed on the bottom surface of the loading platform (1); The sign (3) includes a belly plate (31), an inner side plate (32), and an outer side plate (33). The two sides of the belly plate (31) are respectively connected to the inner side plate (32) and the outer side plate (33). The lower surface of the belly plate (31) can be attached to the upper surface of the tobacco basket. The inner side plate (32) is located inside the tobacco basket, and the outer side plate (33) is located outside the tobacco basket. When the sign (3) is hung on the edge of the first or last tobacco basket and the sign (3) is located in the detection area of ​​the proximity switch (7), the proximity switch (7) is triggered by the upper surface of the belly plate (31) of the sign (3) to generate the first sign signal.

3. The tagging and identification system for tobacco basket identification signs according to claim 2, characterized in that, An infrared emitter is provided on the bottom surface of the loading platform (1). The infrared emitter will irradiate a light spot on the upper surface of the cigarette basket. The area formed by the light spot is located within the detection area of ​​the proximity switch (7). The sign (3) can be placed manually within the area formed by the light spot.

4. A method for identifying tobacco basket labels, based on the tobacco basket label identification system of claim 1, characterized in that, include: S1: The first controller determines whether the tobacco basket below the loading platform (1) is the first tobacco basket or the last tobacco basket. If it is, proceed to step S2. S2: The first controller controls the first alarm (4) to sound; S3: Manually hang an identification sign (3) on the frame edge of the first tobacco basket or the last tobacco basket, and ensure that the first identification sign detector detects the identification sign (3). The first identification sign detector generates a first sign signal and sends the first sign signal to the first controller. S4: When the first reset button is pressed manually, the first reset button generates a first reset signal. After receiving the first license plate signal and the first reset signal, the first controller controls the first alarm (4) to stop alarming.

5. The method for identifying tobacco basket labels according to claim 4, characterized in that, The specific determination method of the first controller in step S1 is as follows: If the first controller receives the start signal from the start button and receives the no-smoke signal from all the first photoelectric switches, then the first controller determines that the tobacco basket under the loading platform (1) is the first tobacco basket. If the first controller receives the no-smoke signal from each of the first photoelectric switches in sequence, then the first controller determines that the tobacco basket below the loading platform (1) is the last tobacco basket.
