[0023] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] See also Figures 1 to 4 , this embodiment provides a fixed-distance tobacco hanging device in a tobacco flue-curing room, including a tobacco hanging unit and a tobacco delivery unit.

[0025] The cigarette hanging unit comprises a cigarette loading chamber 11, multiple rows of columns 12 mounted within the cigarette loading chamber 11, and multiple rows of hanging beams 13 mounted on the columns 12. The hanging beams 13 are provided with guide grooves 14 with open tops along their lengths. It should be noted that the hanging beams 13 are fixed to the sides of the columns 12 so as not to affect the normal operation of the cigarette delivery unit.

[0026] In this embodiment, there are three rows of columns 12, installed on the left, middle, and right sides of the smoke chamber 11. The end of each row of columns 12 corresponding to the door of the smoke chamber 11 is the outer end, and the other end is the inner end. Three rows of hanging beams 13 are fixed from top to bottom on the inner sides of the two side rows of columns 12, and three rows of hanging beams 13 are fixed from top to bottom on both sides of the middle row of columns 12, thereby forming a cigarette hanging space on each side of the middle row of columns 12.

[0027] The cigarette delivery unit comprises a vehicle body 21 movable along the guide groove 14, four motorized wheels 22 mounted on the vehicle body 21, a lifting mechanism 23 mounted on top of the vehicle body 21, a support plate 24 mounted on top of the lifting mechanism 23, and a distance sensor 25 mounted on the vehicle body 21. In this embodiment, the lifting mechanism 23 is a linear motor or an electric cylinder, and a bracket 27 is provided on top of the support plate 24 to support the cigarette rods and prevent them from sliding.

[0028] The vehicle body 21 can be controlled to move forward by rotating the electric wheel 22, and the extension and retraction of the support plate 24 can be controlled by controlling the lifting and lowering of the lifting mechanism 23, so that the device includes at least a jacking state and a retracted state. In the jacking state, the lifting mechanism 23 extends the support plate 24 upward outside the guide groove 14 to lift the cigarette rod or carry it for movement; in the retracted state, the lifting mechanism 23 retracts the support plate 24 into the guide groove 14 to place the cigarette rod on the hanging beam 13.

[0029] For ease of operation, the device also includes a control unit, which includes a controller 31, a wireless communication module 32 electrically connected to the controller 31, and a host computer 33 communicatively connected to the wireless communication module 32. The controller 31 is electrically connected to the electric wheel 22, the lifting mechanism 23 and the ranging sensor 25, respectively, so that commands can be sent to the controller 31 through the host computer 33 to control the actions of the electric wheel 22 and the lifting mechanism 23, and receive the detection distance of the ranging sensor 25.

[0030] In order to improve the accuracy of control, the ranging sensor 25 is a laser ranging sensor, which is installed at the front end of the vehicle body 21 to measure the moving distance of the vehicle body 21, and a diffuse reflection mirror is provided at the inner end of the guide groove 14 to reflect the laser, thereby ensuring the accuracy of the ranging sensor 25.

[0031] To ensure the accuracy of the lifting operation, a position sensor 26 is also installed on the vehicle body 21 to detect the cigarette rod placed in the guide groove 14. The position sensor 26 is electrically connected to the controller 31 and, in conjunction with the distance detection of the laser rangefinder, ensures that the lifting mechanism 23 is directly below the cigarette rod during lifting, ensuring the accuracy of the operation. Specifically, after the position sensor 26 is used, the movement error of the vehicle body 21 can be set. If the position sensor 26 does not detect the cigarette rod after reaching the predetermined position, the vehicle body 21 can move forward or backward a short distance. When the position sensor 26 detects the cigarette rod, the vehicle body 21 stops and then lifts the cigarette rod.

[0032] The method for loading tobacco using the above-mentioned fixed-distance tobacco hanging device in a flue-cured tobacco room is as follows:

[0033] S1 The roasting worker stands at the door of the smoke loading chamber 11 and places a smoke delivery unit in each of the guide slots 14 of the two hanging beams 13 to be loaded with smoke. The initial distance L0 and the smoke rod distance A are set. The smoke rod distance A is the distance between two adjacent smoke rods.

[0034] S2 controls the lifting mechanism 23 to lift the support plate 24 out of the guide slot 14, and places the two ends of the braided cigarette rod on the support plates 24 of the two cigarette delivery units respectively;

[0035] S3 controls the synchronous rotation of the electric wheels 22 of the two cigarette delivery units so that the vehicle body 21 drives the cigarette rods forward. When the vehicle body 21 moves to a position at a distance L=L0, i.e., close to a predetermined position at the inner end of the cigarette loading chamber 11, the lifting mechanism 23 is controlled to retract the support plate 24 into the guide groove 14 so that the cigarette rods are placed on the two hanging beams 13. L is the distance between the vehicle body 21 and the inner end of the guide groove 14.

[0036] S4 controls the vehicle body 21 to move back to the outer end of the guide groove 14, that is, the door of the smoking chamber 11, and repeats steps S2 and S3. When the vehicle body 21 moves to the next distance L=L0+A, the lifting mechanism 23 is controlled to retract the support plate 24 into the guide groove 14, so that the cigarette rods are placed at the next position. Repeat this step, each time L increases by A, and increases N times until all cigarette rods are placed on the two hanging beams 13.

[0037] By using this tobacco loading method, tobacco rods can be sequentially delivered to predetermined positions on the hanging beam 13, achieving rapid and fixed-distance tobacco loading of tobacco rods. The baking personnel do not need to operate in the tobacco loading chamber 11, which greatly improves the tobacco loading efficiency.

[0038] The tobacco adjustment method using the above-mentioned fixed-distance tobacco hanging device in the flue-cured tobacco room is as follows:

[0039] S1 The roasting worker stands at the door of the smoke loading chamber 11, places a smoke delivery unit in each of the guide grooves 14 of the two hanging beams 13 to be adjusted, and sets the adjustment distance B, which is the distance between two adjacent smoke rods;

[0040] S2 controls the lifting mechanism 23 to retract into the guide slot 14, controls the electric wheels 22 of the two cigarette delivery units to rotate synchronously, and moves the vehicle body 21 forward to the position L=L0+A. The lifting mechanism 23 is controlled to lift the support plate 24 out of the guide slot 14 and lift the cigarette rod. The vehicle body 21 is controlled to move to the distance L=L0+B, and then the lifting mechanism 23 is controlled to retract the support plate 24 into the guide slot 14, so that the cigarette rod is placed on the guide slot 14.

[0041] S3 controls the electric wheels 22 of the two cigarette delivery units to rotate synchronously so that the vehicle body 21 moves forward to the position L=L0+2A, controls the lifting mechanism 23 to lift the support plate 24 out of the guide groove 14 and lift the cigarette rod, controls the vehicle body 21 to move to the distance L=L0+2B, and then controls the lifting mechanism 23 to retract the support plate 24 into the guide groove 14 so that the cigarette rod is placed on the guide groove 14;

[0042] S4 repeats step S3, each time the moving distance of the front vehicle body 21 is increased by A, and the moving distance of the rear vehicle body 21 is increased by B, until the adjustment of the positions of all cigarette rods on the two cigarette hanging beams is completed.

[0043] Through this control method, the position of the tobacco rods being baked can be appropriately adjusted in sequence, thereby improving the baking quality and effectively solving the problem that the tobacco rods cannot be effectively adjusted during baking.

[0044] The tobacco unloading method using the above-mentioned fixed-distance tobacco hanging device in the flue-cured tobacco room is as follows:

[0045] S1: The roasting personnel stand at the door of the smoke loading chamber 11, place a smoke delivery unit in each of the guide slots 14 of the two hanging beams 13 to be adjusted, and set the smoke unloading distance C, which is the distance between two adjacent smoke rods. The smoke unloading distance C is A or B. If the smoke is not adjusted during the roasting process, the smoke is processed according to A, otherwise it is processed according to B.

[0046] S2 controls the lifting mechanism 23 to retract into the guide groove 14, controls the electric wheels 22 of the two cigarette delivery units to rotate synchronously, and moves the vehicle body 21 forward to the position L=L0+N*C. The lifting mechanism 23 is controlled to lift the support plate 24 out of the guide groove 14 and lift the cigarette rods. The vehicle body 21 is controlled to move to the outer end of the guide groove 14, and then the lifting mechanism 23 is controlled to retract the support plate 24 into the guide groove 14, so that the cigarette rods are placed on the guide groove 14 for manual unloading.

[0047] S3 controls the electric wheels 22 of the two cigarette delivery units to rotate synchronously, causing the vehicle body 21 to move forward to the position L=L0+(N-1)*C. It then controls the lifting mechanism 23 to lift the support plate 24 out of the guide groove 14 and lift the cigarette rods. It then controls the vehicle body 21 to move to the outer end of the guide groove 14. It then controls the lifting mechanism 23 to retract the support plate 24 into the guide groove 14, allowing the cigarette rods to rest on the guide groove 14 for manual unloading.

[0048] S4 repeats step S3, and the moving distance of the front vehicle body 21 is reduced by C each time, until the unloading operation of all cigarette rods on the two cigarette hanging beams is completed.

[0049] Through this smoke unloading method, the smoke rods that have been baked can be sent to the door of the smoke loading chamber 11 in sequence, and then the smoke rods can be quickly unloaded manually. The baking personnel do not need to operate in the smoke loading chamber 11, which greatly improves the smoke unloading efficiency.

[0050] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
