Description

Technical Field

[0001] This invention relates to the field of automatic unpacking devices, and in particular to a rotary automatic unpacking negative pressure material extraction device and method. Background Technology

[0002] Currently, the unpacking and removal of materials from mask and similar packaging is primarily done manually. This is not only inefficient and labor-intensive, but also results in high labor costs and difficulty in guaranteeing the quality of unpacking. How to automate and mechanize the unpacking and material removal process for mask packaging is an urgent problem to be solved.

[0003] Most existing automatic unpacking devices are designed for larger packaging boxes or bags. They mainly work by moving the material to be unpacked to a specific location, making an opening with a cutter, and then removing the material. For example, patent CN202624759U discloses a fully automatic unpacking and unloading system, which includes a vacuum elevator, a feeding belt conveyor, an unpacking and unloading machine, a discharge hopper, and a filter dust collector. The unpacking and unloading machine is mounted on a support frame, the discharge end of the feeding belt conveyor is connected to the feed end of the unpacking and unloading machine, and the discharge hopper is positioned below the unpacking and unloading machine. The bag-cutting mechanism of the unpacking and unloading machine is adjusted so that the blade cuts a slit in the packaging bag, allowing most of the material in the cut bag to fall into the discharge hopper by its own weight. Patent CN220315571U discloses an automatic unpacking machine, including a frame, a hopper, a transverse cylinder, a lifting cylinder, a swing cylinder, and blades. The lifting cylinder moves the package upwards, and then the transverse cylinder moves the package above the hopper, where it falls back into the hopper. Simultaneously, the swing cylinder vibrates the package, dislodging any remaining material. While this device can automatically unpack and unload materials, its overall structure is complex and more suitable for large, heavy materials; it is unsuitable for unpacking and retrieving materials from smaller, lighter packages such as face masks.

[0004] In view of this, it is necessary to design a device and method for automatically unpacking and dispensing materials from masks and similar packaging in order to solve the above problems. Summary of the Invention

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0032] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0033] like Figure 1-3 As shown, the present invention provides a rotary automatic unpacking negative pressure material handling device, including a first workbench 1, a rotary disk 2 disposed on the first workbench 1, and a clamping mechanism disposed on the rotary disk 2; a feeding station, a cutting station, an inner material handling station, and a packaging bag handling station are arranged sequentially at intervals along the circumference of the rotary disk 2; the clamping mechanism includes a fixing and punching component 4 and clamps respectively located at each station; a cutting component is disposed on one side of the cutting station, an inner material suction component is disposed on one side of the inner material handling station, and a packaging bag suction component is disposed on one side of the packaging bag handling station.

[0034] Based on the above structure, the rotating disk 2 can be used to transfer the workpieces to be unpacked to the corresponding workstations in sequence. At the cutting workstation, the fixing and punching components 4 are used to punch holes in the packaging bag, and the cutting components are used to cut the packaging bag to provide an airflow channel and a movement channel for the suction of the inner material. Then, the inner material is sucked up by negative pressure suction at the inner material retrieval workstation, and finally, the packaging bag is sucked up by negative pressure suction at the packaging bag retrieval workstation, thereby automatically completing the unpacking and material retrieval operations.

[0035] Specifically, the rotary disk 2 is mounted on the first worktable 1 and is driven to rotate by a drive mechanism. This invention does not limit the specific structure of the drive mechanism; as long as the rotary disk 2 can rotate relative to the first worktable 1, it falls within the scope of protection of this invention. When the rotary disk 2 rotates relative to the first worktable 1, the positions of the feeding station, the cutting station, the inner material picking station, and the packaging bag picking station relative to the first worktable 1 remain unchanged. As the rotary disk 2 rotates, the workpieces on the rotary disk 2 can be transferred to different stations. Here, the workpiece refers to the product placed at the station. The workpieces at different stations have different states: the workpiece at the feeding station is a well-packaged product; after being processed at the cutting station, it becomes a packaging bag with holes and cuts; then it is processed at the inner material picking station, becoming an empty packaging bag; finally, it is transferred to the packaging bag picking station, and the empty fixture is transferred to the feeding station to load the well-packaged product.

[0036] More specifically, in some embodiments of the present invention, the interval angle between the feeding station, the cutting station, the inner material picking station, and the packaging bag picking station is 90°. Four clamps, named the first clamp 31, the second clamp 32, the third clamp 33, and the fourth clamp 34, are fixedly installed on the rotary table 2. The interval angle between the four clamps is also 90°. In the initial state, the positions of the first clamp 31, the second clamp 32, the third clamp 33, and the fourth clamp 34 correspond one-to-one with the feeding station, the cutting station, the inner material picking station, and the packaging bag picking station, respectively. With this arrangement, the workpiece on the clamp can be transferred to the next station every 90° rotation of the rotary table 2.

[0037] In its initial state, the fixture at the feeding station is used to clamp the well-packaged workpiece. The well-packaged workpiece is preferably a well-packaged mask or similar product, comprising an inner mask or similar product and an outer packaging bag. The internal dimensions of the outer packaging are larger than the dimensions of the inner product, thus creating an operating space between the inner edge of the outer packaging and the outer edge of the inner product. Drilling and cutting operations performed within this operating space only affect the outer packaging and will not damage the inner product. The size and position of the fixture can be designed according to the dimensions of the outer packaging and the inner product within the workpiece, ensuring that the corresponding positions of the operating space at both ends of the workpiece are exposed for subsequent drilling and cutting. Simultaneously, the fixture is only used to simply fix the workpiece in position, and its clamping force must be less than the suction force of the suction assembly so that the workpiece clamped by the fixture can be sucked up by the suction assembly.

[0038] Please refer to the following: Figure 2 In some embodiments of the present invention, the fixing and punching assembly 4 includes a fixing rod 41 and a first fixing component, a second fixing component, and a punching component connected to the fixing rod 41. The fixing rod 41 can be directly mounted on the first worktable 1, or pass through the rotary disk 2 and connect to the first worktable 1, or be mounted on other external structures to fix the position of the fixing and punching assembly 4, so that the first fixing component, the second fixing component, and the punching component correspond to their respective workstations. Specifically, the first fixing component and the punching component correspond to the cutting workstation and are used to fix and punch the packaging bag of the workpiece at the cutting workstation; the second fixing component corresponds to the inner material picking workstation and is used to fix the packaging bag of the workpiece at the inner material picking workstation.

[0039] In some embodiments of the present invention, the first fixing component and the second fixing component have the same structure. The first fixing component includes a first connecting plate 421 connected to the fixing rod 41, a first clamping cylinder 422 disposed on the first connecting plate 421, and a first clamping cylinder pressure rod 423 connected to the telescopic end of the first clamping cylinder 422. Similarly, the second fixing component includes a second connecting plate 431 connected to the fixing rod 41, a second clamping cylinder 432 disposed on the second connecting plate 431, and a second clamping cylinder pressure rod 433 connected to the telescopic end of the second clamping cylinder 432. The drilling component includes a third connecting plate 431 connected to the fixing rod 41, a needle cylinder 432 disposed on the third connecting plate 431, and a needle 433 connected to the telescopic end of the needle cylinder 432.

[0040] More specifically, the first connecting plate 421, the second connecting plate 431, and the third connecting plate 441 have the same structure. One end of the first connecting plate 421, the third connecting plate 441, and the second connecting plate 431 are connected to the fixing rod 41 from bottom to top, and the other end is used to install the corresponding cylinder. The adjacent connecting plates are at a certain angle so that each cylinder can work independently. At the same time, when the fixture only covers the middle part of the workpiece, exposing the corresponding positions of the operating space at both ends of the workpiece, the ends of the first fixture cylinder pressure rod 423 and the needle 443 are both set at the edge of the workpiece near the center of the rotating disk 2, for fixing and drilling the operating space inside the outer packaging on that side.

[0041] Based on the above setup, when the packaged workpiece is transferred from the feeding station to the cutting station under the rotation of the rotary table 2, the first clamping cylinder 422 pushes the first clamping cylinder pressure rod 423 downward to fix the workpiece. Then, the needle cylinder 442 pushes the needle 443 to move vertically downward quickly to punch a hole in the workpiece's packaging bag. After punching, the needle cylinder 442 pulls the needle 443 up to the initial position until the next workpiece arrives, at which point the punching is performed again, and this cycle continues.

[0042] After the workpiece is fixed by the first clamping cylinder pressure rod 423 and the drilling is completed, the packaging bag is cut by the cutting assembly. For details, please refer to [reference needed]. Figure 3In some embodiments of the present invention, the cutting assembly includes a cutter 56 for cutting the packaging bag of the workpiece at the cutting station, and a cutter servo motor 55 connected to the cutter 56 for driving the cutter 56 to rotate. More specifically, to facilitate the fixing and translation of the cutter 56, the cutting assembly also includes a second worktable 51 placed on the side of the first worktable 1 near the cutting station, a guide rail 52 arranged on the second worktable 51 along the cutting direction of the cutter 56, a slider 53 slidably connected to the guide rail 52, and a motor mounting base 54 connected to the slider 53; the cutter servo motor 55 is disposed on the motor mounting base 54, and the outer extension of the cutter 56 can contact the sealing part of the outer packaging of the workpiece. The guide rail 52 is preferably a pneumatic guide rail, and the number of parallel guide rails is preferably two. The slider 53 is preferably a corresponding pneumatic guide rail slider, so that the motor mounting base 54 can move smoothly on the guide rail 52. The length of the guide rail 52 can be adjusted according to the actual size of the workpiece, so that when the slider 53 moves from one end of the guide rail 52 to the other end, it can complete the cutting of the sealing part of the outer packaging of the workpiece, and the cutter 56 does not contact the workpiece when the slider 53 moves to the end of the guide rail 52.

[0043] With this configuration, during the cutting process, when the slider 53 moves from one end to the other along the guide rail 52, it can drive the motor mounting base 54, the cutting servo motor 55 mounted on the motor mounting base 54, and the rotating cutting blade 56 connected to it to move along the cutting direction, cutting the outside of the workpiece packaging bag to form a cut for removing the inner material of the workpiece. After the cut is formed, the first clamping cylinder 422 pulls the first clamping cylinder pressure rod 423 up to the initial position, and then the rotary table 2 continues to rotate 90°, transferring the cut workpiece to the inner material removal station.

[0044] After the workpiece is transferred to the inner material picking station, the second clamping cylinder 432 pushes the second clamping cylinder pressure rod 433 downward to fix the workpiece's packaging bag. Then, the inner material inside the workpiece's packaging bag is sucked out by the inner material suction assembly. Specifically, in some embodiments of the present invention, the inner material suction assembly includes a first suction fan 61 and a first suction pipe 62 connected to the first suction fan 61. The power of the first suction fan 61 can be selected according to actual conditions so that the inner material of the workpiece can be sucked into the first suction pipe 62. The first suction pipe 62 is composed of multiple pipe sections. For ease of description, the section of the first suction pipe 62 closest to the inner material picking station is referred to as the first pipe. When the first suction fan 61 is turned on, the inner material of the workpiece is sucked into the first pipe. To facilitate the collection of the inner material, a first filter screen 63 is provided in the first pipe to block the inner material. A first gate 64 is provided at the bottom of the pipe between the inlet end of the first pipe and the first filter screen 63. A first material box 65 is provided at the bottom of the first gate 64. When a certain amount of material is collected, the first gate 64 is opened to allow the material to fall into the first material box 65 for collection.

[0045] After the inner material is sucked up in the above manner, the second clamping cylinder 432 pulls the second clamping cylinder pressure rod 433 upward, and then the workpiece with only the packaging bag remaining is transferred to the packaging bag picking station by the rotating disk 2, where the packaging bag suction assembly sucks up the packaging bag. In some embodiments of the present invention, the packaging bag suction assembly and the inner material suction assembly have the same structure, including a second suction fan 71 and a second suction pipe 72 connected to the second suction fan 71. The second suction pipe 72 includes a second pipe near the packaging bag picking station, and a second filter screen 73 is provided in the second pipe. A second gate 74 is provided at the bottom of the second pipe, and a second material box 75 is provided at the bottom of the second gate 74. The specific suction method is the same as that of the inner material suction, and will not be described again here.

[0046] Based on the above-described device, the present invention also provides a rotary automatic unpacking and negative pressure material handling method. The following only uses... Figure 1 Using the device and mask packaging shown in the image as examples, the specific steps of the rotary automatic unpacking negative pressure material handling method are explained below:

[0047] S1. The packaged masks are clamped onto the feeding station by the first clamp 31 corresponding to the feeding station.

[0048] S2. Control the rotary table 2 to rotate 90° counterclockwise, transferring the well-packaged mask to the cutting station. The first clamping cylinder 422 pushes the first clamping cylinder pressure rod 423 downward to fix the workpiece. Then, the needle cylinder 442 pushes the needle 443 to move vertically downward quickly to punch holes in the workpiece's packaging bag. After punching, the needle cylinder 442 pulls the needle 443 back to the initial position (until the next workpiece arrives, punching will be repeated, and this cycle continues). After the workpiece is fixed by the first clamping cylinder pressure rod 423 and punching is completed, the cutter servo motor 55 starts and drives the cutter 56 to rotate. At the same time, the slider 53 drives the cutter servo motor 55 and the cutter 56 to move along the guide rail 52 from one end to the other, so that the cutter 56 cuts the sealed part of the outer packaging of the mask. After the translation ends, the cutting is completed (until the next workpiece arrives, the translation will be reversed, and this cycle continues).

[0049] S3. After the cut is formed, the first clamping cylinder 422 pulls the first clamping cylinder pressure rod 423 to rise to the initial position (until the next workpiece arrives and it is pressed down again, and so on). Then the rotating disk 2 continues to rotate 90° counterclockwise to transfer the cut workpiece to the inner material picking station. The second clamping cylinder 432 pushes the second clamping cylinder pressure rod 433 downward to fix the packaging bag in the workpiece. Then, the first suction fan 61 is started, creating a pressure difference between the first suction pipe 62 and the outside. The holes and cuts on the packaging bag form an airflow channel. With the packaging bag fixed, the unfixed inner material (i.e., the mask) inside the bag is sucked into the first pipe and collected by the first filter screen 63. (After a certain amount of masks are collected, the first gate 64 is opened, allowing the masks to fall into the first material box 65 for collection. Then the first gate 64 is closed.) The inner material suction operation is completed, and the first suction fan 61 stops working (until the next workpiece arrives and is fixed, then it is restarted, and so on).

[0050] S4. The second clamp cylinder 432 pulls the second clamp cylinder pressure rod 433 up to the initial position (until the next workpiece arrives, it is pressed down again, and this cycle continues). Then, the rotary table 2 is controlled to rotate 90° counterclockwise to transfer the empty packaging bag to the packaging bag picking station. At this time, the second suction fan 71 is started, creating a pressure difference between the second suction pipe 72 and the outside, sucking the empty packaging bag into the second pipe, and collecting it by the second filter screen 73 (after a certain amount of empty packaging bags are collected, the second gate 74 is opened, allowing the empty packaging bags to fall into the second material box 75 for collection, and then the second gate 74 is closed). The packaging bag suction operation is completed, and the second suction fan 71 stops working (until the next workpiece arrives, it is restarted, and this cycle continues). At this time, the clamp is unloaded.

[0051] S5. Control the rotary table 2 to rotate 90° counterclockwise to transfer the unloaded fixture to the feeding station.

[0052] S6. Repeat steps S1 to S5 to complete the unpacking and material handling of workpieces in batches.

[0053] Through the above methods, the rotary automatic unpacking negative pressure material handling device and method provided by the present invention are suitable for automated unpacking and material handling of masks and similar packaging, effectively improving work efficiency and material quality consistency, reducing manual labor intensity, and saving labor costs. Furthermore, the rotary automatic unpacking negative pressure material handling device provided by the present invention has a simple structure, is easy to operate, and can meet the needs of actual production and application.

[0054] In summary, this invention provides a rotary automatic unpacking and negative pressure material handling device and method. The device includes a first workbench 1, a rotary disk 2 mounted on the first workbench 1, and a clamping mechanism mounted on the rotary disk 2. Along the circumference of the rotary disk 2, there are sequentially spaced feeding stations, cutting stations, inner material handling stations, and packaging bag handling stations.
