Description

Technical Field

[0001] This utility model relates to the field of tobacco production technology, and in particular to an outer packaging removal device. Background Technology

[0002] Tobacco production involves a large amount of processing materials, such as tobacco leaves. During transportation, tobacco leaves need to be placed in cardboard boxes to ensure their quality. To increase the transport volume, current methods involve stacking cardboard boxes containing tobacco leaves together to form a stack, then wrapping a thin film around the stack to prevent it from scattering. Once the stack arrives at the tobacco processing plant, the film needs to be removed before the tobacco leaves can be taken out of the boxes for drying and other processing. Currently, the film is typically removed manually from the stack, but this method is inefficient and labor-intensive, increasing tobacco processing costs.

[0003] Therefore, there is an urgent need for an outer packaging removal device to solve the above-mentioned technical problems. Utility Model Content

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] like Figures 1 to 3As shown, this embodiment provides an outer packaging removal device configured to remove the film wrapping the outer periphery of a cigarette pack stack 100. The outer packaging removal device includes a support frame 1, a scanning component 2, a cutting component 3, and a peeling component. The support frame 1 has a placement area 10 below it, where the cigarette pack stack 100 is placed. The scanning component 2 is configured to scan the cigarette pack stack 100 placed in the placement area 10 to form three-dimensional information of the cigarette pack stack 100. Specifically, the scanning component 2 performs a full-range scan of the cigarette pack stack 100, forming a three-dimensional model data of the cigarette pack stack 100 within the scanning component 2. The cutting component 3 is placed on the support frame 1 and is communicatively connected to the scanning component 2. The scanning component 2 can communicate the three-dimensional data of the cigarette pack stack 100 to the cutting component 3, which then cuts the film of the cigarette pack stack 100 according to a predetermined cutting path. The cutting component 3 contains a calculation module that stores the planar coordinate data of the placement area 10. After receiving the three-dimensional data of the tobacco pack stack 100, the cutting component 3 combines the planar coordinate data of the placement area 10 and the three-dimensional data of the tobacco pack stack 100 to determine the placement position and state of the tobacco pack stack 100 within the placement area 10. It then simulates and calculates a predetermined cutting path matching the placement position and state of the tobacco pack stack 100, and cuts the film wrapped around the tobacco pack stack 100. The peeling component is configured to remove the cut film from the tobacco pack stack 100, thus separating the film from the tobacco pack stack 100 and removing it from the tobacco pack stack 100. In this embodiment, the placement area 10 can be a marked area created by drawing lines, or it can be a tray, with the side of the tray that receives the tobacco pack stack 100 serving as the placement area 10.

[0033] The outer packaging removal device provided in this embodiment transports the tobacco pack stack 100 to the placement area 10 below the support frame 1. The scanning component 2 performs a full-range scan of the tobacco pack stack 100 to form three-dimensional data of the tobacco pack stack 100. Subsequently, the scanning component 2 communicates the three-dimensional data to the cutting component 3. The cutting component 3 can simulate and calculate a specified cutting path matching the placement posture of the tobacco pack stack 100 in the placement area 10 based on the received three-dimensional data. Then, it can cut the film wrapped around the tobacco pack stack 100 according to the calculated specified cutting path. After the cutting component 3 completes the cutting of the film, the peeling component can quickly remove the film from the tobacco pack stack 100, avoiding manual removal of the film from the tobacco pack stack 100. This improves the efficiency of film removal from the tobacco pack stack 100 and does not require a lot of manpower, thus ensuring the cost of tobacco processing.

[0034] In this embodiment, the scanning component 2 and the cutting component 3 communicate via Bluetooth. Specifically, the scanning component 2 scans the tobacco pack stack 100 to generate three-dimensional data of the stack, which is then transmitted to the cutting component 3 via Bluetooth. Using Bluetooth for data transmission is a common communication method in daily life, such as Bluetooth headsets; therefore, the communication method between the scanning component 2 and the cutting component 3 is not the focus of this invention.

[0035] For example, the cutting assembly 3 includes a robotic arm 31 and a cutting blade 32. The robotic arm 31 is fixedly connected to the support frame 1, which reduces the space occupied by the cutting assembly 3, making the overall layout of the outer packaging removal device more rational and miniaturized. The cutting blade 32 is connected to the robotic arm 31 and is located at the end of the robotic arm 31. The path of the cutting blade 32 can be controlled by manipulating the robotic arm 31. The robotic arm 31 is communicatively connected to the scanning assembly 2. When the scanning assembly 2 communicates the three-dimensional data of the cigarette pack stack 100 to the robotic arm 31, the robotic arm 31 will drive the cutting blade 32 to cut the film wrapped around the cigarette pack stack 100 according to the prescribed cutting path.

[0036] For example, the cutting blade 32 includes a housing, a blade head, and a telescopic mechanism. The blade head and the telescopic mechanism are housed within the housing. The telescopic mechanism allows the blade head to selectively extend out of the housing. When it is necessary to cut the film on the cigarette pack 100, the blade head can be extended out of the housing by controlling the telescopic mechanism. When the cutting assembly 3 is not needed, the blade head can be retracted into the housing by controlling the telescopic mechanism to prevent the cutting assembly 3 from scratching the workers. The telescopic mechanism can be a telescopic rod; alternatively, a drive motor, gears, and racks can be used to selectively extend the blade head out of the housing. The specific structure of the extension mechanism is not specifically limited here. The specific structure and working principle of the robotic arm 31 can be found in existing technology and will not be elaborated upon here.

[0037] In this embodiment, the peeling component includes a clamp. Preferably, the clamp is connected to a robotic arm 31. The clamp can hold the film, and the robotic arm 31 can move the clamp away from the tobacco pack 100, causing the film to detach from the tobacco pack 100. Directly connecting the clamp to the robotic arm 31 makes the structural layout of the peeling component and the cutting component 3 more reasonable and reduces the space occupied. Specifically, when the cutting blade 32 completes the cutting of the film wrapped around the tobacco pack 100, and the clamp holds the film, the robotic arm 31 moves the clamp away from the tobacco pack 100, thus quickly peeling the film off the tobacco pack 100. The specific structure and working principle of the clamp can be referred to in the prior art, and will not be elaborated here.

[0038] Exemplarily, the scanning component 2 includes at least two scanning elements. One scanning element is positioned on top of the support frame 1 and facing the placement area 10, used to scan the length and width data of the tobacco pack 100. The other scanning element is positioned on the side of the support frame 1 and facing the placement area 10, used to scan the height data of the tobacco pack 100. The two scanning elements are interconnected via Bluetooth, enabling the mutual transmission of data between them, meaning that both scanning elements can generate three-dimensional data of the tobacco pack 100. Simultaneously, both scanning elements are connected to the cutting component 3, specifically communicating with the robotic arm 31 within the cutting component 3. This allows the three-dimensional data of the tobacco pack 100 to be exchanged via Bluetooth to the robotic arm 31. The calculation module is located within the robotic arm 31. After obtaining the three-dimensional data of the tobacco pack 100, the calculation module can simulate and calculate the prescribed cutting path for the film wrapped around the tobacco pack 100. For example, the scanning component includes a base and a scanning camera. The base is fixedly mounted on the support frame 1, and the scanning camera is rotated and positioned on the base to ensure the scanning range of the scanning camera. The scanning camera is used to scan the tobacco pack stack 100. Specifically, the scanning camera is communicatively connected to the robotic arm 31 in the cutting assembly 3. The specific structure and working principle of the scanning component can be found in the prior art and will not be elaborated further here.

[0039] Specifically, the specified cutting path includes a first route and a second route connected together. The first route runs from the midpoint of the bottom edge of the side of the tobacco pack 100 along the height direction to the midpoint of the top edge of the side of the tobacco pack 100. The second route runs from the midpoint of the top edge of the side of the tobacco pack 100 to the midpoint of the top surface of the tobacco pack 100. This allows for faster and more convenient peeling of the film from the tobacco pack 100 when the clamp holds the film and the robotic arm 31 moves the clamp away from the tobacco pack 100. Preferably, the first and second routes are perpendicular to each other and are both straight lines, which simplifies the calculation of the specified cutting path.

[0040] Exemplarily, the support frame 1 includes a rectangular frame 11, four legs 12, and a connecting beam 13. The four legs 12 are respectively placed at the four corners of the rectangular frame 11, and the connecting beam 13 connects between two sides of the rectangular frame 11. The lower part of the rectangular frame 11 is the placement area 10. The scanning component 2 and the cutting component 3 are both placed on the connecting beam 13. The setting of the connecting beam 13 makes the overall structure of the support frame 1 more stable and facilitates the installation of the scanning component 2 and the cutting component 3. Preferably, the legs 12 can be set as telescopic structures, so that the legs 12 can be adjusted according to the height of the tobacco pack stack 100, improving the versatility of the support frame 1. For example, the support leg 12 includes two interlocking first support tubes and second support tubes. Specifically, the first support tube is movably placed inside the second support tube. A ball bearing is provided on the first support tube. A plurality of locking holes are provided at intervals along the length direction on the side wall of the second support tube. The first support tube is fixedly connected to the rectangular frame 11. By cooperating with the ball bearing and the locking holes, the length of the support leg 12 can be adjusted, thereby adjusting the height of the rectangular frame 11.

[0041] Preferably, the outer packaging removal device also includes a sensor, which is placed on the support frame 1. The sensor is used to detect whether a stack of cigarette packs 100 is placed in the placement area 10, and the sensor is electrically connected to the scanning component 2. Specifically, when the sensor detects that a stack of cigarette packs 100 is placed in the placement area 10, it sends an electrical signal to the scanning component 2. Subsequently, the scanning component 2 performs a full-range scan of the stack of cigarette packs 100, avoiding the need for staff to independently control the working status of the scanning component 2, reducing manual labor, and improving the intelligence level of the outer packaging removal device.

[0042] In this embodiment, the outer packaging removal device also includes a transfer mechanism for transporting the cigarette pack stack 100. Exemplarily, the transfer mechanism can be a forklift or a robotic arm; no specific limitation is made here.

[0043] Preferably, the outer packaging removal device also includes a recycling bin 4, which is used to collect the film removed from the cigarette pack stack 100 by the peeling assembly. After the robotic arm 31 moves the clamp holding the film away from the cigarette pack stack 100, it transfers the clamp to the recycling bin 4, opens the clamp, and places the peeled film into the recycling bin 4. The recycling bin 4 prevents the peeled film from scattering and affecting the environment.

[0044] Preferably, the outer packaging removal device also includes an electrical box 5, which is electrically connected to the scanning component 2, the cutting component 3, and the peeling component, and is used to supply power to the scanning component 2, the cutting component 3, and the peeling component. The electrical box 5 is equipped with buttons for controlling the power-on and power-off of the scanning component 2, the cutting component 3, and the peeling component. By operating the buttons, the power-on and power-off of the corresponding components can be directly controlled. If the scanning component 2, the cutting component 3, or the peeling component malfunctions during operation, the corresponding component can be powered off directly by operating the corresponding button, further improving the safety of the outer packaging removal device.

[0045] like Figure 4 As shown in the illustration, this embodiment provides a method for removing outer packaging, which uses an outer packaging removal device to remove the film on the cigarette pack stack 100. The outer packaging removal method includes the following steps:

[0046] The stack of tobacco packages 100 is placed in the placement area 10 below the support frame 1. Specifically, the transfer mechanism transfers the tobacco packages to the placement area 10.

[0047] The scanning component 2 is used to scan the tobacco pack stack 100 located in the placement area 10, and to generate three-dimensional information of the tobacco pack stack 100. Specifically, the scanning cameras mounted on the top and sides of the rectangular frame 11 are activated to perform an all-round scan of the tobacco pack stack 100. The scanning data of the two scanning cameras are exchanged via Bluetooth to obtain the three-dimensional data of the tobacco pack stack 100.

[0048] The three-dimensional data of the tobacco pack stack 100 is communicated to the cutting component 3. The cutting component 3 cuts the film wrapped around the tobacco pack stack 100 based on the three-dimensional data of the tobacco pack stack 100. After the cutting component 3 obtains the three-dimensional data of the tobacco pack stack 100, the calculation module inside the cutting component 3 can simulate and calculate the prescribed cutting path that conforms to the position and placement posture of the tobacco pack stack 100. Then, the robotic arm 31 in the cutting component 3 drives the cutting blade 32 to cut the film wrapped around the tobacco pack stack 100 along the prescribed cutting path.

[0049] The peeling assembly is activated to remove the cut film from the tobacco pack stack 100. Specifically, the peeling assembly includes a clamp mounted on the robotic arm 31 of the cutting assembly 3. After the cutting blade 32 in the cutting assembly 3 cuts the film, the blade head of the cutting blade 32 retracts into the housing. The clamp holds the film, and the robotic arm 31 moves the film away from the tobacco pack stack 100, thereby separating the cut film from the tobacco pack stack 100.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
