Description

Technical Field

[0001] The utility model relates to the technical field of tobacco machinery and equipment, in particular to an automatic tobacco hanging device in a tobacco flue-curing room. Background Art

[0002] In the field of tobacco production, intensive baking in a flue-curing room is the current advanced baking method. This method is to fix fresh tobacco leaves with tobacco rods or tobacco clips in the flue-curing room, and then hang them in layers for intensive baking. Our company has developed and applied for a variety of tobacco clip collection and hanging equipment for flue-curing rooms. Our company has disclosed a tobacco clip hanging machine for flue-curing rooms in application number 202321363035.2. A fixed track is set on the mobile tobacco rack to facilitate the lifting and lowering of the tobacco hanging parts to move them out of the flue-curing room, solving the problem of inconvenience in entering the flue-curing room to transport tobacco clips, and the structure is simple and the cost is low. The lifting and lowering of the tobacco hanging parts drives the tobacco clip guard plate to open and close through the linear guide rail, which can automatically push out the tobacco clips on the rack, greatly improving the overall automation level of the device.

[0003] In application number 2024220346482, our company proposed a tobacco leaf lifting system in a tobacco flue-curing room. By providing a movable support edge on the tobacco hanging angle iron which can be rotated upward in one direction through a hinge, the movable support edge can be pushed away when the tobacco clips on the tobacco protection splint rise, slightly above the tobacco hanging angle iron of the layer where tobacco needs to be hung. The tobacco clips on the tobacco protection splint fall down and naturally hang on the movable support edge, thus realizing automatic tobacco hanging at a high place in the tobacco flue-curing room.

[0004] Although it has replaced the manual work of hanging cigarettes and greatly improved the overall automation level of the device, it still requires remote control operation by staff. There are many operation steps and a high degree of precision. It also has certain requirements on the staff's operating skills, and the degree of automation still needs to be improved.

[0034] The present invention will be described in further detail below in conjunction with the embodiments and with reference to the accompanying drawings.

[0035] The utility model discloses an automatic tobacco hanging device for a tobacco flue-curing room. Figure 1-4As shown, the embodiment includes a running track 18 fixed within the tobacco flue-curing room, said running track 18 being higher than the flue-curing room threshold. A horizontally movable vertical lifting and hanging tobacco unit 1 is mounted on said running track 18. A mobile tobacco rack 2 is mounted on one end of said running track 18 near the flue-curing room threshold. A fixed track 23 is mounted horizontally on the frame of said mobile tobacco rack 2 near the flue-curing room threshold, matching the vertical lifting and hanging tobacco unit 1 and the rack.

[0036] The bottom of the up and down lifting cigarette hanging component 1 is provided with a running wheel 20 that matches the running track 18, and the up and down lifting cigarette hanging component 1 is provided with a scissors-fork mechanism 21. The top of the scissors-fork mechanism 21 is horizontally provided with a linear guide pair 7, and two cigarette protection splints 5 are vertically provided on the linear guide pair 7.

[0037] The vertical cigarette hanging unit 1 is also equipped with a running motor 8 that drives the running wheels 20, a hydraulic cylinder 13 that drives the scissor mechanism 21 to open and close, a clamping motor 9 and chain that drives the linear guide pair 7, and an electrical control box 3. The control box 3 houses a PLC controller that is electrically connected to the various electrical components. The vertical cigarette hanging unit 1 is also equipped with a proportional reversing valve that controls the precise hydraulic operation of the hydraulic cylinder 13. There are two clamping motors 9, each controlling the opening and closing of the two cigarette protection clamps 5.

[0038] The vertical lifting and hanging tobacco hanging component 1 is also provided with an operating position distance measuring probe 12 for detecting the horizontal position and spatial height of the tobacco clamp in the flue-curing room, and a lifting control distance measuring probe 11. The tobacco protection clamp plate 5 is provided with an up and down avoidance distance measuring probe 14 and a left and right avoidance photoelectric probe 15 for detecting the distance between the tobacco clamp and the angle steel on which the tobacco clamp is hung in the flue-curing room.

[0039] The vertically movable cigarette hanging unit 1 is equipped with a control magnetic probe 4 at the bottom of the cigarette protection clamp 5 to detect the opening and closing of the cigarette protection clamp 5. The cigarette protection clamp 5 is also equipped with a fault protection probe 6 to detect the horizontal displacement of the cigarette clamp. The running track 18 and the bottom of the vertically movable cigarette hanging unit 1 are both equipped with cooperating positioning magnetic probes 10.

[0040] The mobile cigarette rack 2 includes a cigarette rack frame 19, on which a cigarette clip holder 22 is disposed. Cigarette clips are placed on the cigarette clip holder 22. A weighing sensor 16 is provided on the cigarette rack frame 19 for detecting the weight of the cigarette clips on the cigarette clip holder 22. Four adjustable support wheels 17 arranged in a rectangular shape are provided at the bottom of the mobile cigarette rack 2 frame.

[0041] In specific operation, in the initial state, the up and down lifting cigarette hanging component 1 is located directly below the cigarette clamp support 22 of the mobile cigarette rack 2, and the equipment is started to work. The operating position ranging probe 12 and the lifting control ranging probe 11 transmit the position information of the detected up and down lifting cigarette hanging component 1 and the height information of the cigarette clamp to the PLC controller, and the PLC controller controls the hydraulic cylinder 13 to work, raises the cigarette protection splint 5 to the preset height, and lifts the cigarette clamp on the cigarette clamp support 22; the PLC controller controls the operating motor 8 to work and drive the up and down lifting cigarette hanging component 1 to move to the preset height of the tobacco curing room. The magnetic probe 10 detects the position of the vertical lifting and hanging unit 1 in real time. The PLC controller controls the hydraulic cylinder 13 to raise the tobacco clamp 5 to a preset height and hang the tobacco clip on the angle steel used to hang the tobacco clip in the tobacco flue-curing room. The PLC controller controls the clamp motor 9 to adjust the position of the two tobacco clamps 5 based on the positional relationship between the two clamps 5 and the angle steel used to hang the tobacco clip in the tobacco flue-curing room, as detected by the vertical avoidance distance measurement probe 14 and the left and right avoidance photoelectric probe 15. After the hanging operation is completed, the vertical lifting and hanging unit 1 returns to its initial state for the next hanging operation. The weighing sensor 16 detects the change in the weight of the cigarette clip on the cigarette clip holder 22 to understand the dynamic changes in the amount of cigarette clips hanging. During the hanging process, the fault protection probe 6 detects the horizontal displacement of the cigarette clip in real time. If there is any horizontal displacement, the PLC controller stops the entire device and issues an alarm, waiting for manual intervention.
