Detailed Implementation

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0036] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] like Figures 1-17 As shown, the present invention provides a flue-cured tobacco leaf conveying device, including a tobacco feeding device 200 and a tobacco leaf lifting device 300 located on the rear side of the tobacco feeding device 200.

[0038] The tobacco feeding device includes a tobacco rod frame 201 for horizontally placing tobacco rods 202 woven with tobacco leaves. The tobacco rod frame 201 is driven by a horizontal moving component 208 to move horizontally left and right. A tobacco rod transfer robot 214 is provided above the right end of the horizontal moving component 208. The tobacco rod transfer robot 214 is used to move the tobacco rods 202 on the tobacco rod frame 201 backward and place them on a tobacco rod turnover frame 215. During operation, the horizontal moving component drives the tobacco rod frame and the tobacco rods woven with tobacco leaves to move to the right, so as to convey the tobacco rods woven with tobacco leaves on the tobacco rod frame to the area below the tobacco rod transfer robot. Then, the tobacco rod transfer robot transfers the tobacco rods to the tobacco rod turnover frame. The entire process does not require manual movement of the tobacco rods woven with tobacco leaves, making the operation simple and convenient, reducing manual labor intensity, and improving tobacco rod transfer efficiency.

[0039] The tobacco lifting device includes a vertically mounted gantry support 301. Inside the gantry support 301 is a lifting seat 302 that is driven to rise and fall vertically by a lifting assembly. The lifting seat 302 is equipped with a movable support 303 for horizontally placing the tobacco stem turnover rack 215. The movable support 303 is driven by a longitudinal moving mechanism to move forward and backward longitudinally so as to connect with the tobacco stem placement rack in the tobacco curing barn. The movable support is equipped with a pushing mechanism for pushing the tobacco stem turnover rack 215 longitudinally into the tobacco curing barn. During operation, the lifting device is located in front of the tobacco curing barn 305. Multiple woven tobacco stalks are placed on the stalk turnover rack 304. The stalk turnover rack 215 is placed horizontally on the movable support 303. The lifting seat 302 is driven to rise and fall vertically under the lifting component. The lifting seat 302 drives the movable support 303 and the stalk turnover rack 215 to rise and fall synchronously. When the stalk turnover rack 215 moves to be aligned with the stalk placement shelf 306 in the tobacco curing barn 305, the longitudinal moving mechanism drives the movable support 303 to move backward. The movable support 303 drives the stalk turnover rack 215 to move synchronously, so that the stalk turnover rack 215 is close to and docks with the stalk placement shelf 306. Finally, the pushing mechanism pushes the stalk turnover rack 304 longitudinally into the stalk placement shelf 306 in the tobacco curing barn 305.

[0040] It should be noted that the tobacco rods 202 on the tobacco rod holder 201 are pre-woven by the tobacco weaving robotic arm 213 located on the side, that is: the tobacco weaving robotic arm weaves the tobacco leaves onto the tobacco rod.

[0041] In this embodiment, the tobacco rod transfer robot 214 includes a discharge frame 216 driven to move forward and backward by a longitudinal moving component. The discharge frame is arranged horizontally, and a lifting rod 217 is arranged parallel to the bottom of the discharge frame 216. The lifting rod 217 is driven to move up and down by a vertical moving component arranged on the discharge frame 216. Supporting members 218 for supporting the tobacco rod 202 are respectively provided at the left and right ends of the bottom of the lifting rod 217. During operation, when the tobacco rod frame moves to the bottom of the tobacco rod transfer robot, the longitudinal moving component drives the discharge frame to move forward and backward to directly above the tobacco rod frame. Then, the vertical moving component drives the lifting rod and the supporting members to move downward and close to the tobacco rod. Next, the supporting members support the tobacco rod, the lifting rod returns to its original position, and the discharge frame moves the tobacco rod backward to directly above the tobacco rod turnover frame. Finally, the lifting rod moves the tobacco rod downward and close to the tobacco rod turnover frame, the supporting members release the tobacco rod, and the tobacco rod falls onto the tobacco rod turnover frame, completing the tobacco feeding and discharging.

[0042] In this embodiment, the support bracket 218 includes a pair of front and rear distributed support plates 219. The lower parts of the pair of support plates 219 are bent towards each other and used to contact the cigarette rod. The pair of support plates 219 are driven to move towards or away from each other by a dual-axis cylinder 220 installed at the bottom of the lifting rod 217. When the support bracket 218 moves directly above the tobacco rod 201, the cylinder rods on both sides of the dual-axis cylinder 220 extend simultaneously. At this time, a pair of support plates 219 move in opposite directions along the front-back direction to open. Then, the pair of support plates 219 move downward with the lifting rod 217, so that the pair of support plates 219 are located on the front and rear sides of the tobacco rod, and the lower bent part of the pair of support plates 219 is located below the tobacco rod. The dual-axis cylinder 220 then drives the pair of support plates 219 to move towards each other until they contact each other at the bottom, so that the pair of support plates 219 wrap around the outside of the tobacco rod. Finally, the last pair of support plates 219 move upward with the lifting rod 217, and the lower part of the pair of support plates contacts the tobacco rod, thus supporting the tobacco rod so as to drive the tobacco rod to move.

[0043] In this embodiment, the longitudinal movement component includes a pair of longitudinal conveyor belts 221 distributed on the left and right. Each longitudinal conveyor belt 221 has pulleys at both its front and rear ends. The pulleys at the front ends of the pair of longitudinal conveyor belts 221 are connected by a transversely arranged transmission shaft 222. The transmission shaft 222 is connected to a longitudinal conveyor motor 223. The longitudinal conveyor motor 223 drives the pair of longitudinal conveyor belts 221 to rotate simultaneously through the transmission shaft 222. The lower left and right ends of the discharge moving frame 216 are fixedly connected to the upper parts of the pair of longitudinal conveyor belts 221, respectively. When the pair of longitudinal conveyor belts 221 rotate, they drive the discharge moving frame 216 to move forward and backward.

[0044] In this embodiment, each longitudinal conveyor belt 221 is provided with a longitudinal guide rail 224 on its inner side; the bottom left and right ends of the discharge moving frame 216 are fixed with longitudinal moving sliders 230, and the longitudinal moving sliders 230 slide in cooperation with the longitudinal guide rails 224 on the same side. When a pair of longitudinal conveyor belts rotate, they drive the discharge moving frame to move forward and backward along the longitudinal guide rails.

[0045] In this embodiment, the vertical moving assembly includes a vertical moving frame 225, a vertical lead screw 226 mounted on the vertical moving frame 225, and a pair of vertical guide rails A227 arranged parallel to the left and right sides of the vertical lead screw 226. The bottom of the vertical moving frame 225 is fixedly connected to the middle of the top surface of the lifting rod 217, so that the two are connected as a whole. A vertical conveying motor 225 for driving the vertical lead screw 226 to rotate is installed on the top of the vertical moving frame 225. The vertical lead screw 226 is screwed to a connecting seat 229 fixed in the middle of the rear end face of the discharge moving frame 225. Guide rail mating blocks 230 are respectively provided at the left and right ends of the rear end face of the connecting seat 229. The guide rail mating blocks 230 are slidably engaged with the vertical guide rails A227. During operation, the vertical conveyor motor drives the vertical lead screw to rotate. Since the connecting seat is fixed, the vertical moving frame, vertical lead screw A, vertical conveyor motor, and vertical guide rail A will move up and down vertically as a whole. The vertical moving frame drives the lifting rod to move up and down synchronously.

[0046] In this embodiment, the lateral movement component includes a movable support frame 209 horizontally disposed below the tobacco rod frame 201. The top of the movable support frame 209 is provided with a pair of front and rear distributed lateral guide rails 210. The tobacco rod frame 201 is slidably engaged with the pair of lateral guide rails 210. A lateral conveying chain 211 is horizontally disposed between the pair of lateral guide rails 210. The lateral conveying chain 211 is connected to a movable block fixed at the bottom of the tobacco rod frame 201. The left and right ends of the lateral conveying chain 211 are respectively connected to a drive sprocket and a driven sprocket. The drive sprocket is connected to a lateral conveying motor 212. The lateral conveying motor 212 drives the lateral conveying chain 211 to rotate. The lateral conveying chain 211 drives the tobacco rod frame 201 to move left and right along the pair of lateral guide rails 210.

[0047] In this embodiment, the tobacco rod turnover rack 215 is rectangular in shape. Multiple longitudinally spaced tobacco rod placement slots 233 are provided on the inner sides of both the left and right ends of the tobacco rod turnover rack 215. The positions of the tobacco rod placement slots at the left and right ends correspond one-to-one, and the tobacco rod placement slots are semi-circular in shape. When a tobacco rod is placed on the tobacco rod turnover rack, both ends of the tobacco rod are accommodated within the tobacco rod placement slots.

[0048] In this embodiment, a turnover support frame 232 is provided below the tobacco stem turnover frame 215. The top left and right ends of the turnover support frame 232 are each provided with a longitudinally penetrating movable groove 234. The bottom left and right ends of the tobacco stem turnover frame 215 are each provided with several longitudinally distributed movable wheels 235, which roll in cooperation with the movable grooves 234 located on the same side. The movable grooves and wheels facilitate the forward and backward movement of the tobacco stem turnover frame. In actual use, after multiple tobacco stems are placed on the turnover frame, the lifting rod moves to the front of the turnover frame. Then, the lifting rod moves downward until the support bracket is directly in front of the turnover frame. Finally, the support bracket moves backward, pushing the tobacco stem turnover frame backward along the movable groove, thus enabling the tobacco stem turnover frame to be output onto the movable support of the tobacco leaf lifting device.

[0049] In this embodiment, a discharge support frame 236 is also included. A pair of longitudinal conveyor belts 221 are respectively installed at the top left and right ends of the discharge support frame 236, and the longitudinal guide rails inside each longitudinal conveyor belt are installed at the top of the discharge support frame.

[0050] The working process of the cigarette feeding device: In the initial state, the cigarette rod frame 201 is located at the left end of the movable support frame 209. The cigarette rods 202 on the cigarette rod frame 201 are fed into cigarettes via the cigarette feeding robot arm 213 located on the side. After the cigarette feeding is completed, the feeding begins. Specifically: the horizontal conveyor motor 212 drives the horizontal conveyor chain 211 to rotate, and the horizontal conveyor chain 211 drives the cigarette rod frame 201 to move from left to right along the horizontal guide rail 210. When the cigarette rod frame 201 moves to below the cigarette rod transfer robot arm 214, the vertical moving component drives the feeding moving frame 216 to move in the front-back direction to directly above the cigarette rod frame 201. Then, the vertical moving component drives the lifting rod 217 and the support bracket 218 to move downward and approach the cigarette rod 202. Next, the support bracket 218 holds the tobacco rod, the lifting rod 217 returns to its original position, and the discharge moving frame 216 moves the tobacco rod backward to directly above the tobacco rod turnover frame 215. Finally, the lifting rod 217 moves the tobacco rod downward and close to the tobacco rod turnover frame 215, the support bracket 218 releases the tobacco rod, and the tobacco rod falls into the tobacco rod placement slot 233 on the tobacco rod turnover frame 215, completing the tobacco feeding process. After multiple tobacco rods are placed on the tobacco rod turnover frame, the lifting rod moves to the front of the tobacco rod turnover frame, and then the lifting rod moves downward until the support bracket is directly in front of the tobacco rod turnover frame. Finally, the support bracket moves backward, pushing the tobacco rod turnover frame backward along the moving slide, so that the tobacco rod turnover frame outputs to the moving bracket of the tobacco leaf lifting device.

[0051] It should be noted that the tobacco curing barn 305 has multiple vertically spaced tobacco rod placement shelves 306. Each tobacco rod placement shelf is a pair of left and right distributed placement brackets. The cross-section of the placement brackets can be L-shaped, and the placement brackets extend longitudinally.

The lifting power assembly includes a lifting drive shaft 310 horizontally arranged inside the lower end of the gantry bracket 301. The lifting drive shaft 310 is connected to the lifting drive motor 312 through a sprocket and chain transmission assembly B311. The lifting drive motor is installed at the lower part of the gantry bracket, and the left and right ends of the lifting drive shaft 310 are respectively connected to the sprockets 309 at the lower end of a pair of lifting chains 308. During operation, the lifting drive motor drives the lifting drive shaft to rotate through the sprocket and chain transmission assembly B. The lifting drive shaft simultaneously drives the sprockets at the left and right ends to rotate, thereby driving the pair of lifting chains to rotate. When the lifting chains rotate, they drive the lifting slides located on the same side to move up and down. By controlling the forward and reverse rotation of the lifting drive motor, the lifting slides can be controlled to move up or down.

[0054] In this embodiment, a pair of lifting sliders 313 are provided on opposite sides of a pair of lifting slides 307, with the pair of lifting sliders 313 arranged in a front-to-back configuration.

The rotating frame 304 and the pusher plate 323 are located above the front side of the moving channel 316. Normally, the pusher plate 323 and the moving channel 316 are offset to the left and right. When it is necessary to push the tobacco rod turnover frame 301, the cylinder rod of the first transverse cylinder 322 extends, so that the pusher plate 323 moves laterally to the front of the moving channel 316. Then, the second longitudinal cylinder 320 drives the pusher moving block 321 to move backward. The pusher moving block 321 drives the pusher plate 323 to move synchronously. The pusher plate 323 pushes the tobacco rod turnover frame 304 to move backward along the moving channel 316 to the tobacco rod placement shelf in the tobacco curing room.

[0057] In this embodiment, a second longitudinal guide rail 324 is installed on the pusher bracket 319. The second longitudinal guide rail 324 is located above the moving channel 316, and the pusher moving block 321 slides in cooperation with the second longitudinal guide rail 324.

[0058] In this embodiment, the top of the gantry support 301 is provided with a traveling wheel 327 to facilitate the movement of the entire lifting device and thus adapt to the tobacco curing barn in different positions.
