Description

Technical Field

[0001] This invention relates to the field of palletizing equipment technology, specifically to an automated palletizing equipment for chemical production and its operating method. Background Technology

[0002] In modern continuous and large-scale chemical production systems, various finished and semi-finished chemical products are packaged in bags, drums, boxes, etc., and then need to be neatly stacked on pallet surfaces using palletizing equipment to form standardized stack structures for subsequent warehousing, transportation, and loading / unloading operations. Automated palletizing equipment, with its advantages of high stacking neatness, high operating efficiency, and adaptability to the pace of large-scale chemical production, has been widely used in the downstream processes of various chemical products such as chemical raw materials, chemical preparations, and rubber and plastic products. It is one of the core pieces of equipment ensuring the automated and routine operation of chemical production lines.

[0003] Existing chemical palletizing equipment can only complete the automated stacking and placement of materials, and its function is relatively simple. After the materials are stacked, the materials in the stack are relatively loose. In order to avoid problems such as displacement, scattering, and collapse of the stack during storage, handling and long-distance transportation, and to isolate the chemical materials from external dust and moisture, and to ensure the safety and integrity of chemical products during storage and transportation, it is necessary to wrap a layer of plastic protective film around the outside of the stacked material.

[0004] The film wrapping process generally relies on manual operation. The manual wrapping process is cumbersome and time-consuming. Operators need to hold the film roll, bend over repeatedly, and wrap it layer by layer around the stack. The entire process involves a large amount of repetitive movements and is extremely labor-intensive. Summary of the Invention

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 In the existing technology, the film wrapping work after stacking is usually done manually. The manual film wrapping process is cumbersome and time-consuming. Operators need to hold the film roll, bend over repeatedly, and wrap it layer by layer around the stack. The entire process involves a large amount of repetitive movements and is extremely labor-intensive.

[0021] Therefore, this embodiment proposes an automated palletizing device for chemical production, which can perform film wrapping after palletizing. Specifically, as shown in the example... Figure 1 As shown, the system includes a conveyor belt 100 and a robotic arm 200. The conveyor belt 100 is used to transport materials, and the robotic arm 200 is used to grab materials from the conveyor belt 100 and stack them. A winding mechanism 300 is also provided next to the conveyor belt 100, on which a pad 400 is placed. In use, the robotic arm 200 grabs materials from the conveyor belt 100 and stacks them on the pad 400. At the end of stacking or during stacking, the winding mechanism 300 aligns and wraps plastic film around the materials.

[0022] like Figure 2 As shown, the winding mechanism 300 includes a chassis 301, on which a first splicing track assembly 303 is slidably mounted, and a second splicing track assembly 302 is also slidably mounted. The first splicing track assembly 303 and the second splicing track assembly 302 can be spliced ​​to form a complete circular track. The second splicing track assembly 302 is also provided with a walkable walking mechanism 304. The walking mechanism 304 carries a film roll and can walk along the first splicing track assembly 303 and also along the spliced ​​circular track, thereby realizing the transverse and longitudinal film winding of the stack.

[0023] like Figure 3 As shown, the chassis 301 includes a circular base plate 30101, and an annular slide rail 30102 is provided on the side of the circular base plate 30101. The first splicing track assembly 303 can slide on the annular slide rail 30102. Two sets of support frames 30103 are also stacked on the circular base plate 30101. In use, the pad 400 is placed on the two sets of support frames 30103 to support the pad 400 and the stacks on it.

[0024] like Figure 3As shown, the second splicing track assembly 302 includes an upper track 30205 and a lower track 30204, which slide together. Both the upper track 30205 and the lower track 30204 are L-shaped, and they slide together to form a U-shaped structure. In actual palletizing, the overall stacking height of the pallets varies, with some stacks being higher and others lower. Therefore, in this embodiment, the upper track 30205 and the lower track 30204 are designed to slide, that is, the overall height of the second splicing track assembly 302 is adjusted by sliding the upper track 30205 and the lower track 30204 to meet the height requirements of different pallets. Specifically, as shown... Figure 4 As shown, a first U-shaped mating groove 30209 is provided at the sliding connection between the lower track 30204 and the upper track 30205, such as... Figure 5 As shown, the upper track 30205 is slidably disposed within the first U-shaped mating groove 30209, in conjunction with... Figure 5 and 11 As shown, a first gear 30212 is rotatably mounted on the upper track 30205, and a first rack 30208 is fixedly mounted on the lower track 30204 within the first U-shaped mating groove 30209. The first gear 30212 meshes with the first rack 30208 for transmission. A first motor 30210 is fixedly mounted on the upper track 30205, and the output end of the first motor 30210 is fixedly connected to the first gear 30212. That is, the first motor 30210 drives the first gear 30212 to rotate, and the first gear 30212 meshes with the first rack 30208 for transmission. The height between the lower track 30204 and the upper track 30205 can be adjusted. The vertical section of the upper track 30205 can overlap with the vertical section of the lower track 30204 and be retracted to reduce the height.

[0025] like Figure 5 As shown, the upper track 30205 has upper moving grooves 30207 on both sides, and the upper moving grooves 30207 are adapted to the shape of the upper track 30205. The lower track 30204 has lower moving grooves 30206 on both sides, and the lower moving grooves 30206 are adapted to the shape of the lower track 30204. As the vertical section of the upper track 30205 overlaps with the vertical section of the lower track 30204, the upper moving grooves 30207 and the lower moving grooves 30206 will also overlap. Therefore, there will be a step at the transition between the upper moving grooves 30207 and the lower moving grooves 30206. In order to achieve a perfect transition between the two, this embodiment has a bevel on the lower moving groove 30206, that is, the transition between the lower moving groove 30206 and the upper moving groove 30207 is ground into a slope to facilitate the movement of the walking mechanism 304 on it.

[0026] like Figure 3 and 4As shown, the second splicing track assembly 302 is slidably mounted on the circular base plate 30101. Specifically, the circular base plate 30101 has two sets of threaded grooves 30201 symmetrically arranged. A first threaded rod 30202 is rotatably mounted on the threaded groove 30201. A movable plate 30203 is threadedly engaged with the first threaded rod 30202. Both sets of movable plates 30203 are slidably engaged with the threaded grooves 30201. The bottom horizontal section of the lower track 30204 is rotatably mounted on the two sets of movable plates 30201. Between 203, and a second motor 30211 is fixedly installed on one of the movable plates 30203. The second motor 30211 drives the lower rail 30204 to rotate relative to the movable plate 30203. In use, the lower rail 30204 can be moved as a whole to the end of the threaded groove 30201, and then the lower rail 30204 can be rotated to be flush with the circular base plate 30101. This allows the lower rail 30204 to be stored between the two sets of support frames 30103 to save floor space.

[0027] like Figure 4 and Figure 6As shown, in this embodiment, the first splicing track assembly 303 and the second splicing track assembly 302 can be spliced ​​together to form a complete annular track, and perform longitudinal film winding on the pallet. At the same time, the first splicing track assembly 303 can also work independently to achieve a wrapping pattern winding on the outer periphery of the pallet. The first splicing track assembly 303 includes a movable seat 30301, which is slidably disposed on the annular slide rail 30102. That is, the movable seat 30301 can perform circumferential movement around the circular base plate 30101. The movable seat 30301 and the annular slide rail 30102 are implemented by, but are not limited to, gear and rack meshing transmission. The specific implementation method is a conventional technical means well known to those skilled in the art, and will not be described in detail here. A sliding plate 30302 is slidably mounted on the top of the movable base 30301. A second rack 30304 is mounted on the side of the sliding plate 30302. A second gear 30303 is rotatably mounted on the movable base 30301. The second gear 30303 meshes with the second rack 30304, and the second gear 30303 is driven by a motor. A back plate 30305 is fixedly mounted on one end of the movable base 30301. A slot 30306 is formed on the back plate 30305. Both ends of 30306 are open, and a side rail is provided on the slot 30306. The side rail includes a first vertical rail 30307 and a second vertical rail 30308. The first vertical rail 30307 and the second vertical rail 30308 are in sliding engagement. The first vertical rail 30307 is provided with a second U-shaped engagement groove 30311. The principle of the sliding engagement is the same as that of the engagement between the lower rail 30204 and the upper rail 30205, which will not be elaborated on here. The first vertical rail 30307 and the second vertical rail 30308 on the side rail are independently driven by a third motor 30310. The first vertical track 30307 is provided with a first moving groove 30313 on both sides, and the second vertical track 30308 is provided with a second moving groove 30312 on both sides. The splicing method of the first moving groove 30313 and the second moving groove 30312 is the same as the splicing method between the upper moving groove 30207 and the lower moving groove 30206.

[0028] The first vertical track 30307 is located inside the slot 30306. The back plate 30305 is also equipped with several electric positioning pins 30309. When the first vertical track 30307 is located inside the slot 30306, the positioning pins 30309 will lock the first vertical track 30307 onto the back plate 30305. At this time, the side track can move with the back plate 30305. When the side track is spliced ​​with the lower track 30204 and the upper track 30205, the positioning pins 30309 on the back plate 30305 are released, so that the back plate 30305 is separated from the side track. The splicing point of the lower track 30204 and the upper track 30205 is also equipped with positioning pins 30309. When the side track is spliced, the positioning pins 30309 can lock the spliced ​​lower track 30204, upper track 30205 and side track together to form a complete track.

[0029] like Figure 7 and Figure 8 As shown, the splicing method of the side track, the lower track 30204, and the upper track 30205 is as follows: the first vertical track 30307 on the side track is spliced ​​with the upper track 30205, and the second vertical track 30308 is spliced ​​with the lower track 30204. The splicing method is the same at both locations. Taking one location as an example, specifically, the upper track 30205 is provided with a splicing groove 30213, and the second vertical track 30308 is provided with a splicing block 30314. The splicing groove 30213 and the splicing block 30314 are spliced ​​together to achieve the splicing between the two. After the splicing is completed, the positioning pin 30309 is activated to fix the two together. The positioning pin 30309 is preferably set on the upper track 30205. The upper moving groove 30207 on the upper track 30205 is spliced ​​with the first moving groove 30313 on the second vertical track 30308.

[0030] The working principle of the first splicing track assembly 303 and the second splicing track assembly 302 is as follows: When longitudinal multi-layer winding of the pallet is required, the side track, lower track 30204, and upper track 30205 on the first splicing track assembly 303 are spliced ​​together to form a complete circular track. The traveling mechanism 304 travels along the complete circular track to achieve longitudinal multi-layer winding of the pallet. When side-encircling winding of the pallet is required, the side track and lower track on the first splicing track assembly 303 are connected... Separate from the upper track 30204 and the upper track 30205, and rotate the second splicing track assembly 302 to a horizontal position and retract it. The walking mechanism 304 moves to the side track, and the side track can move in a circular motion with the moving seat 30301 to realize the wrapping of the palletized side pattern. The longitudinal wrapping is followed by the side wrapping, that is, the longitudinal wrapping is followed by the side wrapping. During this process, the walking mechanism 304 needs to be moved to the first splicing track assembly 303, so as to realize continuous wrapping without film, solve the wrapping time problem, and eliminate the need for manual wrapping.

[0031] It should be emphasized that the core improvement of this embodiment lies in the fact that the track in this embodiment can be disassembled and spliced, realizing free switching between two winding modes. By splicing and separating the first and second splicing track components, and flipping and storing them, a complete circular track or an independent side track can be formed as needed, realizing longitudinal multi-layer winding and side full-encirclement winding of the material stack respectively. One set of equipment is compatible with two wrapping processes, and the equipment has strong versatility and is applicable to a wider range of stack types. 。 Furthermore, the continuous and uninterrupted film wrapping process shortens the winding operation time. After longitudinal winding is completed, the walking mechanism directly switches from the circular track to the side track, significantly reducing the time spent on changing auxiliary processes and improving the overall film wrapping efficiency. The film wrapping is automatically wound around the track in coordination with the walking mechanism, eliminating the need for manual hand-held film wrapping, reducing labor intensity, saving labor costs, and avoiding the defects of uneven tightness, missed wrapping, and material waste caused by manual wrapping. The wrapping and covering quality is uniform and stable.

[0032] Example 2 It is understandable that in Embodiment 1, since the first and second splicing track assemblies can be wound in different ways, when conventionally the film is wound vertically first and then sideways, it is necessary to cut the film, manually re-apply the film, and fix the film head. The two processes are interrupted and time-consuming. Therefore, this embodiment also proposes a walking mechanism 304, which can simultaneously adapt to the splicing and independent operation requirements of the first and second splicing track assemblies.

[0033] like Figure 9 As shown, the walking mechanism 304 includes an intermediate control box 30401. A bidirectional threaded rod 30402 and a limit rod 30403 are rotatably mounted on the intermediate control box 30401. The intermediate control box 30401 can control a motor to drive the bidirectional threaded rod 30402 to rotate. The driving method is a conventional technique well-known to those skilled in the art and will not be described in detail here. Both sides of the bidirectional threaded rod 30402 are threadedly engaged with the walking assembly. A walking wheel 30406 is rotatably mounted on the walking assembly. One of the walking wheels 30406 is driven by a fourth motor 30407. A mounting bracket 30408 ​​is also rotatably mounted on the intermediate control box 30401. A sleeve 30409 is rotatably mounted on the mounting bracket 30408. A film roll 30410 is fitted onto the sleeve 30409. The film roll 30410 is fixed to the sleeve 30409 by a buckle 30411. Both the sleeve 30409 and the mounting bracket 30408 ​​are driven to rotate by a motor.

[0034] The working principle of the traveling mechanism 304 is as follows: During use, the distance between the two sets of traveling wheels 30406 is adjusted by rotating the bidirectional threaded rod 30402, so that the two sets of traveling wheels 30406 are respectively located in the upper moving groove 30207 and clamped to prevent slippage. Then, the traveling wheels 30406 are driven to move in the track groove to realize the winding of the film roll 30410. When longitudinal winding is performed, the mounting bracket 30408 ​​rotates to the position as shown in the figure. Figure 9 As shown, the mechanism 304 moves to the first splicing track assembly 303 and rotates the mounting bracket 30408 ​​to a vertical position. The circumferential movement of the first splicing track assembly 303 is used to achieve a wrap-around wrap-around effect on the palletizing side.

[0035] It should be emphasized that the core improvement of this embodiment is that: this solution utilizes the track interconnection design, after the longitudinal winding is completed, the traveling mechanism 304 directly switches from the ring track to the side track, and the same roll of film completes two windings continuously without interruption, eliminating the process of film breaking and reloading.

[0036] Example 3 It is understandable that in Embodiment 2, the track adopts a segmented splicing assembly structure. Due to limitations in processing accuracy and assembly tolerance, uneven transition bevels inevitably form at the splicing joints of each track component. The traveling mechanism 304 relies on the traveling wheel 30406 engaging with the track to achieve guided movement. When the traveling wheel 30406 moves to the splicing bevel position, the clamping gap between the traveling wheel 30406 and the track increases instantaneously due to the track drop, and the effective clamping force decreases, posing a safety hazard of the traveling mechanism 304 falling and affecting the stability of the equipment's continuous film wrapping operation.

[0037] To address the aforementioned issues, this implementation also includes a buffer mechanism to ensure the safe movement of the walking mechanism 304, such as... Figure 10 As shown, the walking assembly includes an end connecting plate 30404, a mounting box 30405 slidably mounted on the bottom of the end connecting plate 30404, a walking wheel 30406 rotatably mounted on the mounting box 30405, a mounting plate 30412 fixedly mounted on the mounting box 30405, and a telescopic mechanism 30413 fixedly mounted between the mounting plate 30412 and the end connecting plate 30404. The telescopic mechanism 30413 includes, but is not limited to, a spring-assisted telescopic rod structure. When the two sets of walking wheels 30406 clamp and walk on the track, the telescopic mechanism 30413 can provide buffer compensation when passing through the bevel at the track splice, so as to realize the safe walking of the walking mechanism 304.

[0038] This embodiment is equipped with a buffer mechanism. Through the structural design of buffer compensation and flexible transition, the impact caused by the height difference at the bevel is eliminated, so that the walking wheels can smoothly transition to the splicing bevel and avoid the walking wheels falling off due to clamping failure. This improves the running stability of the walking mechanism and the overall working reliability of the machine.

[0039] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention.
