Description

Technical Field

[0001] This invention relates to the field of visual inspection technology, and in particular to an automatic feeding device for large-leaf crops. Background Technology

[0002] Currently, for large-leaf crops such as tobacco, tobacco collection stations typically collect tobacco through manual grading or sorting using intelligent sorting equipment. Intelligent sorting equipment is the primary method of tobacco collection due to its numerous advantages over manual grading.

[0003] However, since the leaves of large-leaf crops come in various shapes and sizes, and are fully spread, half-spread, or not spread at all, and there is a serious problem of sticking together, it is not only difficult to use the tobacco leaves delivered by tobacco farmers for automatic feeding into intelligent sorting equipment for grading, but also the results are not good.

[0004] Large-leaf crops freshly cured in the curing barn and packed in tobacco clips, after being rehydrated, have characteristics such as even stems and loose texture. Therefore, it is ideal to send such tobacco leaves into intelligent sorting equipment for testing. However, current intelligent sorting equipment does not have a mechanism that can directly use tobacco clips for feeding. At the same time, existing equipment cannot perform actions such as disassembling tobacco clips, changing tobacco clips, and sorting tobacco leaves. Summary of the Invention

The subsequent clamps flow and feed material along the clamp flow line; the first carrier rotating module and the second carrier rotating module are respectively set at both ends of the clamp flow line module; after the material is fed, the empty clamps switch from the clamp flow line to the clamp return flow line through the first carrier rotating module; the return synchronous belt module transports the clamps on the return flow line to the second carrier rotating module; the second carrier rotating module switches the clamp flow line again; the pusher cylinder pushes the clamps flowing through the second carrier rotating module to below the active unlocking module.

This reduces the work of tobacco farmers in disassembling tobacco clips, rehydration, tobacco sorting, and logistics turnover, greatly reducing the labor and economic costs of the entire tobacco sorting cycle, and also maintaining a relatively consistent tobacco feeding uniformity.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0044] like Figure 1 The automatic feeding device 100 for large-leaf crops shown is used in conjunction with the intelligent tobacco leaf sorting equipment 200, such as... Figure 12 As shown, this method reduces manual labor by changing the manual task of feeding large-leaf crops to directly feeding tobacco clips. This simplifies the process, significantly reduces the frequency of actions, and optimizes labor efficiency from 2 people per machine to 0.5 people per machine. The material input uses standard tobacco clips 5 (containing tobacco). The equipment buffers and unclamps the standard tobacco clips, then transfers the large-leaf crops 6 to a self-made clamp. The self-made clamp is then moved and sorted, thus separating the large-leaf crops (from one clip of tobacco into 3-5 pieces). The sorted large-leaf crops are then automatically fed into the large-leaf crop sorting equipment.

[0045] Specifically, it includes an automatic tobacco clip feeding device 1 and an automatic tobacco leaf sorting device 2; it also includes a recycling conveyor 3 and a recycling box 4; the recycling conveyor and recycling box are located below the automatic tobacco clip feeding device and the automatic tobacco leaf sorting device.

[0046] like Figures 2-3As shown, the automatic cigarette clip feeding device 1 includes a cigarette clip conveying mechanism 11, a cigarette clip lifting mechanism 12, a cigarette clip disassembly mechanism 13, and a tobacco leaf sorting comb mechanism 14.

[0047] The cigarette clip conveying mechanism 11 includes a pulley module 111 and a floating guide wheel module 112 disposed below the pulley module. The cigarette clip is conveyed on the floating guide wheel module via the pulley module. A blocking cylinder 113 is provided at the end of the guide wheel module, and the cigarette clip is stopped at a preset position by the blocking cylinder. The floating guide wheel module can accommodate cigarette clips of different thicknesses. When the cigarette clip is conveyed to the position of the blocking cylinder, it is sensed by a proximity switch located near the position of the blocking cylinder. Then the blocking cylinder extends, and the blocking bar or blocking component keeps the cigarette clip in the preset position so that the two ends of the cigarette clip can be clamped subsequently.

[0048] The cigarette clip lifting mechanism 12 includes a lifting cylinder assembly 121; the lifting end of the lifting cylinder assembly is provided with a mounting plate 122; the mounting plate is provided with a feeding cylinder assembly 123; the extended end of the feeding cylinder assembly is provided with a clamping cylinder assembly 124 and a cigarette clip unlocking cylinder assembly 125; when the clamping cylinder assembly is activated, it clamps both ends of the cigarette clip, and the pressure head of the cigarette clip unlocking cylinder assembly extends to press the latch of the cigarette clip.

[0049] The cigarette clip disassembly mechanism 13 includes a cigarette clip upper frame clamping block 131, which is pressed down by a cylinder to hold the inner side of the cigarette clip upper frame; the cigarette clip upper frame clamping block is connected to a cigarette clip disassembly cylinder 132, and the cigarette clip disassembly cylinder pulls the cigarette clip upper frame clamping block to open the cigarette clip.

[0050] like Figures 4-11 As shown, the automatic tobacco leaf sorting device 2 includes an active unlocking module 21, a clamp streamline module 22, and a passive unlocking module 23.

[0051] like Figure 5 As shown, the active unlocking module 21 includes an unlocking pressure plate 211, which is sleeved on a linear bearing 212 and connected to an unlocking cylinder 213. When the unlocking pressure plate is pressed down, the clamp opens; when the unlocking pressure plate is retracted, the clamp 24 holds the tobacco stem.

[0052] like Figure 6 As shown, the passive unlocking module 23 includes a connecting plate 232 fixed to the frame via a support column 231; an unlocking guide strip 233 is provided at the bottom of the connecting plate; the unlocking guide strip is a wedge-shaped block.

[0053] like Figure 7As shown, the fixture streamline module 22 includes a fixture streamline 221, a fixture return streamline 222, a first pusher module 223, a second pusher module 224, a third pusher module 225, a buffer synchronous belt module 226, a return synchronous belt module 227, a first carrier rotation module 228, a second carrier rotation module 229, and a pusher cylinder 2210; the buffer synchronous belt module has multiple fixtures buffered on it, and the first pusher module separates the multiple fixtures located on the buffer synchronous belt module one by one; the second pusher module and The third pushing module alternately pushes the jigs after order splitting to flow and load material on the jig flow line; the first carrier rotation module and the second carrier rotation module are respectively set at both ends of the jig flow line module; after loading, the empty jigs switch from the jig flow line to the jig return flow line through the first carrier rotation module; the return synchronous belt module transports the jigs on the return flow line to the second carrier rotation module; the second carrier rotation module switches the jig flow line again; the pushing cylinder pushes the jigs flowing through the second carrier rotation module to below the active unlocking module.

[0054] The first pushing module consists of a pushing motor A, a synchronous belt module A, and a one-way pushing device, among other components; the second pushing module consists of a pushing motor B, a synchronous belt module B, and a one-way pushing device, among other components; the third pushing module consists of a pushing motor C, a synchronous belt module C, and a one-way pushing device, among other components; and the pushing cylinder consists of a cylinder and a one-way pushing device, among other components.

[0055] like Figure 8 As shown, the fixture streamline / fixture return streamline includes a linear guide, and the first carrier rotation module and the second carrier rotation module are respectively disposed at both ends of the linear guide; the first carrier rotation module and the second carrier rotation module each include a rotary motor, and a rotary arm is connected to the rotation shaft of the rotary motor through a fixed plate; the fixture achieves streamline switching through the rotary arm.

[0056] like Figure 9 As shown, the clamp 24 includes a clamp body 241, push blocks 242 are provided at both ends of the clamp body, and a slider 243 is provided at the bottom of the clamp body. The clamp body moves in the clamp streamline module through the push blocks and the slider. The clamp body is connected to clamp fingers 244. A clamp pressure plate 245 is provided at the bottom of the clamp fingers, and a foam strip 246 is provided on the clamp pressure plate. A second connecting rod 248 is provided in the middle of the clamp fingers, and the second connecting rod 248 is rotatably connected to the first connecting rod 247. A guide post 249 is provided at the center of the clamp body, and the clamp fingers are normally closed through a self-locking spring 2410 and the guide post.

[0057] like Figure 10As shown, the buffer synchronous belt module 226 is composed of components such as buffer drive pulley 2261, buffer idler pulley 2262, buffer synchronous belt 2263, buffer motor & reducer 2264, buffer feed block 2265 and buffer synchronous belt baffle 2266.

[0058] like Figure 11 As shown, the return synchronous belt module 227 consists of components such as the return drive pulley 2271, the return idler pulley 2272, the return synchronous belt 2273, the return motor & reducer 2274, the return material feeding block 2275, and the return synchronous belt baffle 2276.

[0059] The automatic tobacco clip feeding device enables clip buffering and clip disassembly; the automatic tobacco leaf sorting device enables functions such as changing clips for large-leaf crops, sorting large-leaf crops into individual bundles, feeding large-leaf crops, and clamp return. Specifically, the tobacco clip conveying mechanism enables clip buffering, conveying, disassembling, and return; the clamp conveying flow line enables clip changing, sorting, feeding, and the circulation and return of self-made clamps; the active unlocking module enables unlocking of the entire set of self-made clamps and clip changing for large-leaf crops; and the passive unlocking module enables unlocking of a single self-made clamp and feeding large-leaf crops. The clamping flow and return line provides guidance and flow switching functions for the self-made clamps; the self-made clamps realize functions such as clamping large-leaf crops, and the self-made clamps are normally closed clamps, which can ensure that large-leaf crops are effectively clamped throughout the process, while eliminating unnecessary cables and enabling the circular flow and return of multiple sets of clamps; the pushing module A realizes the function of dividing the self-made clamps into orders, thereby realizing the division of large-leaf crops into bundles; the pushing modules B and C alternately push the self-made clamps after order division to flow on the flow line, thus realizing the function of feeding large-leaf crops together with the passive unlocking module; pushing... The cylinder pushes the self-made fixture from the return line to the flow line via the carrier rotating module B until the entire set of self-made fixtures is filled; after the large-leaf crop is changed, the buffer synchronous belt module pushes the entire set of self-made fixtures to the buffer position. After the material pushing module A divides a set of self-made fixtures into units, the buffer synchronous belt module continues to push the self-made fixtures to the units, and so on, until all self-made fixtures are divided into units; the return synchronous belt module uses the material feeding block to push the self-made fixture from the flow line to the return line via the carrier rotating module A in a step-by-step manner, and transports the self-made fixture to the carrier rotating module B.

[0060] The automatic tobacco clip feeding device performs actions such as disassembling tobacco clips, changing tobacco clips for large-leaf crops, and sorting large-leaf crops according to the characteristics of large-leaf crops being uniform in stem and loose in the tobacco clips.

[0061] Based on the characteristics of large-leaf crops being uniform in stem and loose in tobacco clamps, the automatic tobacco leaf sorting device uses a set of self-made clamps to hold the large-leaf crops in the tobacco clamps all at once. Then, through the pushing module A, the self-made clamps are separated one by one at the buffer position, thereby realizing the automatic sorting of large-leaf crops.

[0062] The entire feeding process is as follows:

[0063] The cigarette clips are manually loaded into the automatic feeding device for large-leaf crops. The cigarette clip conveying mechanism transports the cigarette clips to the preset position via a pulley module and a floating guide wheel module. The floating mechanism accommodates different thicknesses of cigarette clips through a floating device, enabling efficient conveying of different types of cigarette clips. A blocking cylinder is installed at the preset position, and a proximity switch is used to improve accuracy. When the cigarette clip reaches the preset position, the blocking cylinder extends to initially position the cigarette clip. Subsequently, the two ends of the cigarette clip are clamped by the clamping cylinder assembly. After the cigarette clip is clamped, it is pushed towards the disassembly position by the feeding cylinder assembly.

[0064] After the cigarette clip is conveyed to the disassembly position, the upper frame clamping block of the cigarette clip disassembly mechanism presses down and locks the inner side of the upper frame of the cigarette clip by the action of a cylinder, ensuring that the cigarette clip is well clamped in all directions. Then, the cigarette clip lifting mechanism lifts the cigarette clip to the replacement position. Below the active unlocking module, there is a set of self-made clamps that have returned to their positions. There are usually 32 clamps. Therefore, pressing down on the active unlocking module can open the set of self-made clamps, but at this time the cigarette clip is not disassembled, and the tobacco stems of the large-leaf crops in the cigarette clip are within the clamping range of the self-made clamps. The large-leaf crop dividing comb mechanism operates to divide the large-leaf crops in the cigarette clip into independent groups, minimizing the probability of stem overlap between groups. Subsequently, the active unlocking module retracts, allowing the self-made clamps to hold the tobacco stems. Then, the cigarette clip disassembly mechanism activates, the unlocking cylinder presses the cigarette clip's latch, and the locking structure between the upper and lower frames of the cigarette clip is released. Because the upper frame clamping block is pneumatically pressed down and latches onto the inside of the upper frame, the disassembly cylinder moves backward, pulling the upper frame of the cigarette clip open. Simultaneously, the lower frame of the cigarette clip retracts with the feeding cylinder, at which point the cigarette clip is disassembled. Subsequently, the large-leaf crops are transferred from the cigarette clip to the homemade clamp. The buffer synchronous belt module transports the entire homemade clamp set to the buffer position.

[0065] Afterwards, the tobacco clip disassembly mechanism closes the tobacco clips that no longer contain large-leaf crops (the closing action of the tobacco clip is the opposite of the opening action of the tobacco clip, which will not be described here), and pushes the tobacco clips onto the belt conveyor mechanism; the belt conveyor mechanism returns the empty tobacco clips; after the empty tobacco clips are full, it reminds personnel to pick up and put away the tobacco clips.

[0066] Meanwhile, the clamps in the buffer position are divided into individual clamps through the pusher module A, thus enabling the sorting of large-leaf crops. During sorting, the pusher motor A drives the unidirectional pusher through the synchronous belt module A to push the individual clamps forward to an intermediate position;

[0067] Then, pusher modules B and C alternately transport the pre-sorted, centrally located self-made clamps to carrier rotation module A through their respective module structures. During this process, the large-leaf crops in the self-made clamps are unlocked by the passive unlocking module and dropped into the intelligent large-leaf crop sorting equipment for sorting. Carrier rotation module A rotates the self-made clamps, which have completed the loading of large-leaf crops, 180° up and down to the clamp return line. The return synchronous belt module transports the self-made clamps to carrier rotation module B. Carrier rotation module B rotates the self-made clamps 180° up and down to the clamp flow line, and the pusher cylinder continuously pushes the self-made clamps to the clamp changing position until the entire set of clamps is in place. Once the entire set of clamps is in place, the next cycle can begin.

[0068] The above description is only a specific embodiment of the present invention. Various examples and illustrations do not constitute a limitation on the substantive content of the present invention. Those skilled in the art can make modifications or variations to the above-described specific embodiments after reading the specification without departing from the substance and scope of the invention.
