Description

Technical Field

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

[0002] Currently, tobacco collection at tobacco processing stations typically involves manual grading or sorting using intelligent sorting equipment. However, current intelligent sorting equipment relies on manual loading and sorting, lacking automated sorting mechanisms. Furthermore, the incoming large-leaf crops vary in size, shape (fully expanded, partially expanded, unexpanded, etc.), and exhibit significant adhesion. Therefore, directly using tobacco delivered by farmers for automated sorting is difficult and ineffective. Freshly cured large-leaf crops packed in tobacco clamps, after rehydration, possess characteristics such as even stems and loose texture, which are conducive to automation. However, these large-leaf crops require tobacco clamps for transport, and currently, there is no equipment for automatically sorting these clamps. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an automatic bunching device for large-leaf crops, which solves the problem of refining the particle size (shopping) of large-leaf crops when they are automatically smoked.

[0004] The technical solution adopted by the present invention to solve its technical problem is: an automatic bunching device for large-leaf crops, including an active unlocking module, a clamping streamline module and a passive unlocking module; the active unlocking module opens the clamp on the clamping streamline module and clamps the large-leaf crops located on the tobacco clip; the clamping streamline module sorts the clamps into bunches, and the passive unlocking module opens the clamps to realize the bunching and feeding of large-leaf crops.

[0005] Furthermore, the fixture streamline module of the present invention includes a fixture streamline, a fixture return streamline, a first pusher module, a second pusher module, a third pusher module, a buffer synchronous belt module, a return synchronous belt module, a first carrier rotation module, a second carrier rotation module, and a pusher cylinder; the buffer synchronous belt module is buffered with multiple fixtures, 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 pusher module alternately push the separating unit. 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.

[0006] Furthermore, the active unlocking module of the present invention includes an unlocking pressure plate, which is sleeved on a linear bearing and connected to an unlocking cylinder; when the unlocking pressure plate is pressed down, the clamp opens; when the unlocking pressure plate is retracted, the clamp holds the tobacco stem.

[0007] Furthermore, the passive unlocking module of the present invention includes a connecting plate fixed to the frame by a support column; an unlocking guide strip is provided at the bottom of the connecting plate; the unlocking guide strip is a wedge-shaped block.

[0008] Furthermore, the fixture of the present invention includes a fixture body, push blocks at both ends of the fixture body, and a slider at the bottom of the fixture body. The fixture body moves within the fixture streamline module via the push blocks and the slider. The fixture body is connected to fixture fingers, and a fixture pressure plate is provided at the bottom of the fixture fingers. A foam strip is provided on the fixture pressure plate. A second connecting rod is provided in the middle of the fixture fingers, and the second connecting rod is rotatably connected to the first connecting rod. A guide post is provided at the center of the fixture body, and the fixture fingers are normally closed via a self-locking spring and the guide post.

[0009] Furthermore, the fixture streamline / fixture return line of the present invention 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 rotating arm is connected to the rotation shaft of the rotary motor through a fixed plate; the fixture realizes the switching of the streamline through the rotating arm.

[0010] The beneficial effects of this invention are that it solves the defects existing in the background technology and solves the problems of the original technology, which requires manual labor to sort and apply tobacco to large-leaf crops, resulting in high labor costs, low efficiency, and difficulty in maintaining consistent tobacco uniformity. It not only reduces labor and improves equipment efficiency, but also maintains relatively consistent tobacco uniformity, greatly reducing the labor and economic costs of the entire tobacco sorting cycle.

[0027] 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.

[0028] like Figures 1 to 8 The device 2 shown is an automatic sorting device for large-leaf crops. The material input uses a standard cigarette clip 5 (containing cigarettes). The device buffers and unclamps the standard cigarette clip, and then transfers the large-leaf crops into a self-made clamp. The self-made clamp is then moved and sorted, thereby realizing the sorting of large-leaf crops (from one clip of cigarettes into 3-5 pieces of cigarettes). The sorted large-leaf crops are then automatically fed into the large-leaf crop sorting equipment.

[0029] It includes an active unlocking module 21, a fixture streamline module 22, and a passive unlocking module 23;

[0030] 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.

[0031] 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.

[0032] 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 is equipped with multiple fixtures, 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... The pushing module alternately pushes the jigs after order splitting to flow along the jig flow line for loading; 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.

[0033] 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.

[0034] The fixture streamline / fixture return line 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 rotating arm is connected to the rotation shaft of the rotary motor through a fixed plate; the fixture achieves streamline switching through the rotating arm.

[0035] The clamp 24 includes a clamp body 241, with push blocks 242 at both ends and a slider 243 at the bottom. The clamp body moves through the push blocks and slider in the clamp streamline module. The clamp body is connected to clamp fingers 244, with a clamp pressure plate 245 at the bottom of each clamp finger and a foam strip 246 on the clamp pressure plate. A second connecting rod 248 is provided in the middle of each clamp finger and is rotatably connected to a first connecting rod 247. A guide post 249 is provided at the center of the clamp body, and the clamp fingers are normally closed by a self-locking spring 2410 and the guide post.

[0036] The buffer synchronous belt module 226 consists of components such as a buffer drive pulley 2261, a buffer idler pulley 2262, a buffer synchronous belt 2263, a buffer motor & reducer 2264, a buffer feed block 2265, and a buffer synchronous belt baffle 2266. The return synchronous belt module 227 consists of components such as a return drive pulley 2271, a return idler pulley 2272, a return synchronous belt 2273, a return motor & reducer 2274, a return feed block 2275, and a return synchronous belt baffle 2276.

[0037] This device enables functions such as changing clamps for a whole set of large-leaf crops, separating large-leaf crops into individual orders, loading large-leaf crops, and clamp return. The clamp conveyor flow line enables functions such as changing clamps for large-leaf crops, separating large-leaf crops into individual orders, loading large-leaf crops, and the circulation and return of self-made clamps; the active unlocking module enables the unlocking of the entire set of self-made clamps and the changing of clamps for large-leaf crops; the passive unlocking module enables the unlocking of a single self-made clamp and the loading of 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.

[0038] The action process is as follows:

[0039] 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.

[0040] 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.

[0041] Afterwards, the tobacco clip disassembly mechanism closes the tobacco clips that no longer contain large-leaf crops again (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 the personnel to pick up and put away the tobacco clips.

[0042] 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;

[0043] 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.

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.
