Description

Technical Field

[0001] This application belongs to the field of material packaging frame technology, and specifically relates to a material packaging frame palletizing and warehousing production line. Background Technology

[0002] Some flexible material bales, such as those containing tobacco leaves, are made from raw tobacco leaves obtained after the tobacco leaves have been harvested and cured during the framing process. These raw tobacco leaves are typically packaged and transported in burlap sacks (i.e., raw tobacco bales). After the trucks transport the raw tobacco bales to the designated location, automated equipment stacks the raw tobacco bales into standard tobacco frames with mesh baffles on two sides and openings on the other two sides, following a pattern of four raw tobacco bales per layer (two side by side) and four layers per frame.

[0003] The tobacco re-drying industry stipulates that each raw tobacco bale should weigh 50kg. However, due to the varying size, length, and weight of each tobacco leaf, and the inconsistent density of the raw tobacco leaves packed into sacks, the dimensions of each 50kg raw tobacco bale are inconsistent. This makes it difficult to achieve continuous and stable automated framing and palletizing operations using automated equipment. For example, when the total width of two side-by-side raw tobacco bales exceeds the inner width of the standard frame, they cannot be framed; or when the total height of the same layer of raw tobacco bales exceeds the height, the framing of the second, third, or fourth layer of raw tobacco bales cannot be completed. These abnormalities result in low framing and palletizing efficiency, ultimately preventing the achievement of fully automated, continuous, and stable framing and palletizing of raw tobacco bales. Summary of the Invention

[0038] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0039] The following description, with reference to the accompanying drawings, describes a material packaging frame palletizing and warehousing production line according to this application.

[0040] like Figure 1 and Figure 2As shown, this application provides a material packaging frame palletizing and warehousing production line, including a gripping device 100, a transfer mechanism 200, a material frame storage station 300 for storing empty material frames 600, and a material conveying line 400. The material conveying line 400 includes a loading station 40, an inspection station 41, and a gripping station 42 arranged sequentially along the material conveying direction. The inspection station 41 is used to screen the material bags 700 conveyed from the loading station 40 and recover defective material bags. The gripping station 42 is used to receive qualified material bags conveyed from the inspection station 41, and the gripping station 42 is equipped with... The material frame fixing position 421 is used to fix the material frame; wherein, the gripping device 100 is provided on the gripping station 42, and the gripping device 100 is used to grip qualified material bags on the gripping station 42 and stack them into the empty material frame 600 on the material frame fixing position 421; the transfer mechanism 200 can move between the material frame storage station 300 and the gripping station 42, and the transfer mechanism 200 is used to transfer the empty material frame 600 on the material frame storage station 300 to the material frame fixing position 421, and is also used to transfer the loaded material frame at the material frame fixing position 421 to the warehousing station for warehousing.

[0041] Among them, such as Figure 6 As shown, the empty material frame 600 can be used to stack material bales 700. The material bales 700 can be raw tobacco bales containing tobacco leaves, or bales 700 containing flexible materials, such as sawdust or hay. For ease of understanding, the following explanation uses tobacco bales containing tobacco leaves as an example.

[0042] In this embodiment, material packages 700 are unloaded from a truck onto a material conveyor line 400. The material conveyor line 400 transports the material packages 700 to an inspection station 41 for inspection, where defective material packages 700 are rejected. Qualified material packages that pass inspection are then transported along the inspection station 41 to a picking station 42. Simultaneously, a transfer mechanism 200 transfers empty material frames 600 from the material frame storage station 300 to the material frame fixing position 421 at the picking station 42 for fixing. The picking device 100 picks up qualified material packages from the picking station 42 and places them into empty material frames 600 within the material frame fixing position 421 for stacking. After stacking, the fully loaded material packages 700 are transferred to the warehousing station by the transfer mechanism 200 for storage. This material packaging and palletizing production line can detect defective material packages, improve the pass rate of 700 material packages being framed, and ensure the stability and continuity of automatic framing when the cigarette packages have inconsistent external dimensions, realizing fully automated operation of cigarette package conveying, gripping, palletizing and warehousing.

[0043] In some embodiments, such as Figure 3As shown, a material bag recycling frame 411 is also provided on one side of the inspection station 41 along the width direction. The inspection station 41 is provided with a vision inspection mechanism 412 and a pushing mechanism 413. The vision inspection mechanism 412 is set near the discharge end of the loading station 40 and is used to inspect the material bag 700 conveyed from the loading station 40. The pushing mechanism 413 is used to push the detected defective material bag into the material bag recycling frame 411 for recycling.

[0044] The visual inspection mechanism 412 can be a camera. The entire material packaging frame palletizing and warehousing production line also includes a central control unit and an analysis unit. The camera sends the acquired image information to the analysis unit for image analysis to determine whether the acquired material package 700 image has defects such as missing QR code 800 or unraveling rope. The judgment result is then sent to the central control unit, which controls whether the pushing mechanism 413 is activated based on the judgment result. When a defective material package without QR code 800 or unraveling rope is detected, the pushing mechanism 413 is activated and pushes the detected defective material package to the material package recycling box 411 on one side for recycling.

[0045] In addition, a lifting and rotating mechanism 47 is also provided at the inspection station 41. When the vision inspection mechanism 412 can also detect the orientation of the QR code 800 on the material package 700, the lifting and rotating mechanism 47, through the cooperation of the lifting cylinder 474 and the rotating motor 477, lifts and rotates the original tobacco package, adjusting the QR code 800 to the same direction, ensuring that the QR code 800 faces outward after the material package 700 is stacked in the empty material frame 600, facilitating scanning and information reading. For example, Figure 4As shown, the lifting and rotating mechanism 47 includes a mounting base plate 478 and a lifting support plate 472 arranged at intervals along the height direction. The mounting base plate 478 is installed on the side of the inspection station. A linear guide sleeve 479 is provided on the mounting base plate 478. One end of the linear guide rod 473 movably passes through the linear guide sleeve 479 and the lifting support plate 472. A rotary support 475 is provided on the lifting support plate 472. A lifting frame 471 for lifting the raw tobacco pack is provided on the rotary support 475. A rotary motor 477 is installed on the lifting support plate 472. A drive gear 476 is coaxially connected to the drive shaft of the rotary motor 477. The outer periphery of the drive gear 476 meshes with the outer periphery of the rotary support 475. A lifting cylinder 474 is also installed on the side of the mounting base plate 478 facing the lifting support plate 472. The piston rod of the lifting cylinder 474 is connected to the lifting support plate 472. When the piston rod of the lifting cylinder 474 drives the lifting support plate 472 to move up and down, it can drive the linear guide rod 473 to move up and down relative to the linear guide sleeve 479. Since the mounting base plate 478 is fixed, the up and down movement of the linear guide rod 473 can drive the movement of the lifting support plate 472, thereby realizing the height movement of the lifting frame 471. When the rotary motor 477 is started, the rotary motor 477 drives the drive gear 476 to rotate, thereby driving the slewing support 475 to rotate, so as to realize the rotational movement of the lifting frame 471.

[0046] In some embodiments, the inspection station 41 is further provided with a first blocking mechanism 414. When the vision inspection mechanism 412 detects that the material package 700 is a defective material package, the first blocking mechanism 414 is used to block the defective material package from being conveyed forward.

[0047] To prevent defective material packages from accidentally flowing to the material grabbing station 42, when a defective material package 700 is detected, the first blocking mechanism 414 is activated and positioned in front of the material package 700 in the conveying direction to block the defective material package from being conveyed forward and wait for the pushing mechanism 413 to push and recycle it.

[0048] In some embodiments, the area between the first material blocking mechanism 414 and the visual inspection mechanism 412 is a judgment area. The discharge side of the judgment area is also provided with a buffer position 415. The buffer position 415 is connected to one end of the material bag recycling frame 411. The pushing mechanism 413 includes a first linear drive member 4131 and a second linear drive member 4132. The first linear drive member 4131 is located on the judgment area and is used to drive the defective material bag to move along the width direction to the buffer position 415. The second linear drive member 4132 is provided on the buffer position 415 and is used to drive the defective material bag on the buffer position 415 to move along the length direction and fall into the material bag recycling frame 411.

[0049] The first linear drive 4131 and the second linear drive 4132 both include a push plate and a drive cylinder connected to the push plate. The piston rod of the drive cylinder drives the push plate to move to achieve linear motion.

[0050] The first linear drive unit 4131 is located on the side of the judgment area away from the buffer position 415. When a defective package 700 is detected in the judgment area, the pusher plate of the first linear drive unit 4131 pushes the defective package toward the buffer position 415. When the defective package enters the buffer position 415, the pusher plate of the second linear drive unit 4132 pushes the defective package toward the package recycling frame 411 on one side to recycle the defective package into the package recycling frame 411. In this embodiment, by initially screening and removing defective packages from the packages 700, the yield rate of package 700 in the frame can be improved, thereby improving the work efficiency.

[0051] In some embodiments, such as Figure 5 As shown, the material gripping station 42 is also provided with a positioning mechanism 422 for limiting the material package 700 and a second blocking mechanism 423. The positioning mechanism 422 includes a limiting plate 4221 and a linear drive assembly 4222. There are two limiting plates 4221, which are arranged at intervals along the width direction of the material gripping station 42, and a flow channel is formed between the two limiting plates 4221 through which the material package 700 passes. The linear drive assembly 4222 is used to drive the two limiting plates 4221 to move relative to or towards each other to clamp or release the material package 700 from the width direction. The second blocking mechanism 423 is located in front of the flow channel and is used to block or release the material package 700 conveyed in the flow channel.

[0052] When the material package 700 is conveyed to the gripping station 42, a flow channel is formed between the two limiting plates 4221, thereby limiting the material package 700 in the width direction. The second blocking mechanism 423 blocks the material package 700 from being conveyed forward through the flow channel, and then the gripping device 100 grips the material package 700. The linear drive assembly 4222 includes a rotary drive component and a crank-connecting rod structure. Two sliders on the crank-connecting rod structure are respectively connected to the two limiting plates. When the rotary drive component drives the crank in the crank-connecting rod structure to rotate, it can drive the connecting rod to pull the sliders in a linear reciprocating motion, thereby realizing the relative or opposite movement of the two limiting plates. It should be noted that the crank-connecting rod structure is a common structural form in the prior art that converts reciprocating motion and rotary motion, and will not be described in detail here.

[0053] It should be noted that both the first blocking mechanism 414 and the second blocking mechanism 423 include a blocking plate and a drive cylinder located below the blocking plate and connected to it. When blocking is not required, the piston rod of the drive cylinder drives the blocking plate to move downward to a position flush with the surface of the workstation, ensuring that the material package 700 is conveyed smoothly. When blocking is required, the piston rod of the drive cylinder passes through the workstation and drives the blocking plate to move upward to block the advance of the material package 700.

[0054] In addition, each gripping device 100 of the production line is equipped with two material frame fixing devices 500 to fix the two material frames. After one material frame is stacked, the gripping device 100 then stacks the next material frame, realizing continuous operation of the gripping device 100 and improving production efficiency.

[0055] In some embodiments, the material packaging frame palletizing and warehousing production line further includes a first slide rail 43 arranged in parallel on one side of the material conveying line 400. The extension direction of the first slide rail 43 is the same as the extension direction of the material conveying line 400, and the transfer mechanism 200 slides in cooperation with the first slide rail 43.

[0056] In this embodiment, by setting a first slide rail 43 parallel to the material conveying line 400, the conveying process of the material bag 700 and the transfer process of the material frame can be carried out independently and simultaneously without interference, thereby improving the framing efficiency of the production line. One end of the first slide rail 43 extends to the position of the material frame storage station 300, and the other end extends to the position of the material gripping station 42. The transfer mechanism 200 moves along the first slide rail 43, allowing it to reciprocate between the material gripping station 42 and the material frame storage station 300, ensuring the continuity of the framing operation on the production line.

[0057] In some embodiments, the material packaging frame palletizing and warehousing production line further includes a second slide rail 44 that connects to the side of the first slide rail 43 opposite to the material conveying line 400. The warehousing station is located on the second slide rail 44, and the transfer mechanism 200 can transfer from the first slide rail 43 to the second slide rail 44. The extension direction of the second slide rail 44 is perpendicular to the extension direction of the first slide rail 43 and is set away from the material conveying line 400, so that the second slide rail 44 and the material conveying line 400 do not interfere with each other.

[0058] Specifically, the transfer mechanism 200 is a rail-guided RGV mother-daughter trolley, which includes a mother trolley and a daughter trolley mounted on the mother trolley. When the rail-guided RGV mother-daughter trolley carries the opened empty material frame 600 to the point where the two longitudinal rails of the mother trolley are aligned with the two longitudinal fixed rails at the bottom of the material frame fixing position 421, the daughter trolley detaches from the mother trolley and transfers the empty material frame 600 along the longitudinal rails and the longitudinal fixed rails to the top of the material frame fixing device 500. At this time, the daughter trolley lowers the empty material frame 600 into the material frame fixing device 500 to complete the positioning of the empty material frame 600 on the material frame fixing position 421.

[0059] When the material frame is filled with material bag 700, the rail-guided RGV mother and daughter trolleys move to the point where the two longitudinal rails of the mother car are aligned with the two longitudinal fixed rails at the bottom of the material frame fixing position 421. The daughter trolley then separates from the mother car and enters below the material frame fixing device 500 along the longitudinal rails. At this time, the fully loaded material frame is unlocked from the material frame fixing device 500. The daughter trolley rises to a position that can support the fully loaded material frame and returns to the position of the mother car. Then, the mother car drives the daughter trolley to move along the second slide rail 44 to the storage station to wait for storage.

[0060] In some embodiments, the material frame storage station 300 is disposed on the first slide rail 43 and includes a material frame buffer position 30, a material frame destacking position 31, and a material frame opening position 32; the material frame buffer position 30 is used to buffer multiple empty material frames 600 that are stacked and locked in sequence along the height direction; the material frame destacking position 31 is disposed between the material frame buffer position 30 and the material frame opening position 32, and the material frame destacking position 31 is used to receive the empty material frames 600 output from the material frame buffer position 30 and disassemble them into a single folded empty material frame 600; the material frame opening position 32 is used to receive the single folded empty material frame 600 conveyed from the material frame destacking position 31 and open it.

[0061] In this embodiment, a forklift or AGV transports stacks of 10 empty folded crates 600 to the crate buffer position 30. A rail-guided RGV (RGV trolley) then lifts and transports the stacks of 10 empty folded crates 600 to the crate destacking position 31. The destacking mechanism breaks the stacks of 10 empty folded crates 600 into individual empty folded crates 600 from bottom to top. The rail-guided RGV then transports the individual empty folded crates 600 to the crate opening position 32, where the folded mesh baffles on both sides of the empty crates are manually opened and opened. The destacking mechanism is a conventional destacking structure in the prior art and will not be described in detail here. The rail-guided RGV then transports the opened and opened empty crates 600 to the crate fixing device 500 for robotic stacking. The fully stacked crates are then transported by the rail-guided RGV to the warehousing station for weighing and storage.

[0062] In some embodiments, the loading station 40 includes a powered conveyor belt 401 and a non-powered conveyor belt 402 connected sequentially along the material conveying direction. The non-powered conveyor belt 402 is arranged at an angle. The non-powered conveyor belt 402, by virtue of its inclined arrangement, allows the material package 700 on it to be directly transported to the inspection station 41 by its own weight and initial velocity. The powered conveyor belt 401 is horizontally arranged, and its main conveying method relies on external driving force. When the material package 700 is unloaded from the truck onto the powered conveyor belt 401, the powered conveyor belt 401 is activated to transport the material package 700 to the non-powered conveyor belt 402.

[0063] In some embodiments, a conveyor ladder 45 is provided above the material conveyor line 400, and a protective fence 46 is provided on one side of the material conveyor line 400. The protective fence 46 primarily serves to isolate personnel from the equipment, and it has multiple safety doors, each corresponding to a robot. When a robot palletizing station malfunctions, the corresponding safety door on the protective fence 46 is opened, the robot at the malfunctioning station stops working, and personnel can access the fault location via the conveyor ladder 45 to handle the issue. After the fault is resolved, the safety door is closed and the reset button is activated, allowing the robot to resume operation.
