[0037] refer to Figures 1 to 4 Some embodiments of this disclosure provide an unpacking device for removing the wrapping material 12 outside the cigarette label paper 11, including a support part 2, a cutting device 5, a positioning device 4 and a detection device 3.

[0038] The support unit 2 is provided with an operating channel for placing the cigarette label paper 11 with the wrapped material 12. A cutting device 5 is provided at one end of the extending direction of the operating channel, with the cutting direction perpendicular to the extending direction of the operating channel, and is configured to cut the wrapped material 12 to release it. A positioning device 4 is movably provided relative to the support unit 2 and is configured to be perpendicular to the extending direction of the operating channel, approaching or moving away from the centerline of the operating channel, to apply force to the cigarette label paper 11 placed on the operating channel, so that the position of the wrapped material 12 to be cut corresponds to the cutting position of the cutting device 5. A detection device 3 is provided on the operating channel and is configured to obtain detection information on whether a positioning mark 120 exists at its location. The positioning mark 120 is provided on the wrapped material 12 and is configured to indicate the position of the wrapped material 12.

[0039] Optionally, the wrapping material 12 is kraft paper. Optionally, the cutting device 5 is movably mounted on the support part 2 along the extension direction of the operating channel. Optionally, the positioning device 4 includes a clamping mechanism. The positioning device 4 includes two opposing clamping parts disposed opposite each other in the operating channel. The two clamping parts can move simultaneously toward each other or move individually to apply force to the cigarette label paper 11 simultaneously. After the stacked cigarette label paper 11 is positioned and the wrapping material 12 is cut, it can be conveyed to the subsequent process.

[0040] The unpacking device provided in the embodiments of this disclosure can determine the position of the package 12 by detecting the positioning mark 120 on the package 12. When the package 12 is not cut by the cutting device 5, the position of the package 12 can also reflect the position of the cigarette label paper 11. If the overall placement of the cigarette label paper 11 and the package 12 changes and deviates from the corresponding position of the cutting position, the detection information of the detection device 3 will change accordingly.

[0041] Therefore, the unpacking device provided in the embodiments of this disclosure can determine whether the placement of the cigarette label paper 11 is normal based on changes in the detection information, thereby reducing the risk of errors during the unpacking process.

[0042] In some embodiments, the positioning mark 120 is a color block mark, and the detection device 3 is a photoelectric sensor or a vision sensor.

[0043] Optionally, in order to detect color block marks efficiently and accurately, the detection device 3 employs a color mark detector.

[0044] Figure 2 The outline of the wrapping material 12 and the cigarette label paper 11 wrapped therein, as shown in some embodiments of this disclosure, is illustrated. It can be seen that two positioning marks 120 are disposed on one surface of the wrapping material 12 and arranged along one edge of that surface. (See reference...) Figure 3 and Figure 4During the unpacking operation, the surface of the package 12 with the positioning mark 120 is aligned with the detection device 3.

[0045] In some embodiments, the two detection devices 3 are respectively disposed on both sides of the extension direction of the operating channel.

[0046] In some embodiments, the two detection devices 3 are arranged side by side and their orientation is perpendicular to the extension direction of the operating channel.

[0047] In some embodiments, the supporting part 2 is a frame structure, and two detection devices 3 are respectively installed on the inner sides of two oppositely arranged crossbeams at the top of the frame structure.

[0048] Optionally, the unpacking device includes two brackets 6 corresponding to the two detection devices 3, the two brackets 6 being connected to the corresponding crossbeams, and the detection devices 3 being mounted on the corresponding brackets 6.

[0049] In the above embodiments, the detection device 3 is disposed inside the frame structure, and the cigarette label paper 11 is placed above the frame structure. The detection device 3 does not require additional space and has little impact on the unpacking operation.

[0050] refer to Figures 2 to 4 Considering that the shape and size of the cigarette label paper 11 outside the two sides of the wrapped item 12 are different in the wrapped state, in some embodiments, the detection positions of the two detection devices 3 are at different distances from the center line of the operation channel.

[0051] The distance between the detection position of the detection device 3 and the operating channel can be adjusted by adjusting the distance between the detection device 3 and the corresponding crossbeam on the frame structure. Optionally, the distances between the two detection devices 3 and their corresponding crossbeams are 20mm and 30mm, respectively.

[0052] In order to better accommodate cigarette label paper 11 of different sizes and its wrapping material 12, and to better accommodate the detection needs of different positions of positioning marks 120 on wrapping materials 12 of different specifications, in some embodiments, the detection position of the detection device 3, that is, the position of the detection device 3 relative to the operating channel, is adjustable.

[0053] In some embodiments, the distance between the detection position of the detection device 3 and the centerline of the operation channel is adjustable.

[0054] In some embodiments, the detection position of the detection device 3 is adjustable along the extension direction of the operating channel.

[0055] In some embodiments, the unpacking device includes an alarm device and a control device. The alarm device is configured to issue an alarm signal. The control device is signal-connected to the positioning device 4, the detection device 3, and the alarm device and is configured to: in response to motion information of the positioning device 4 moving away from the centerline of the operating channel and in response to detection information that the positioning mark 120 is not present at the location of any of the detection devices 3, cause the alarm device to issue an alarm signal.

[0056] The motion information of the positioning device 4 mentioned above can be obtained from the change of the drive signal of the driving device of the positioning device 4, or from the detection information of external sensors corresponding to the positioning device 4, such as position detection sensor, displacement sensor, speed sensor, etc.

[0057] In the above embodiments, when the positioning device 4 is far from the centerline of the operating channel, it indicates that the positioning device 4 has performed a positioning operation on the cigarette label paper 11. If no positioning mark 120 is found at the location of any detection device 3, it indicates that the stacked cigarette label papers 11 may have the following problems: 1. The cigarette label paper 11 is not placed in the predetermined direction; 2. The positioning device 4 has not reached the limit position of the movement path, causing the cigarette label paper 11 to not be pushed into place and offset from the cutting position; 3. The cigarette label paper 11 is tilted under the force of the positioning device 4. At this time, the unpacking equipment issues an alarm signal as a prompt, thereby timely restricting the movement of relevant execution components in subsequent processes and reducing the risk of errors in subsequent processes.

[0058] In some embodiments, the unpacking device includes an alarm device, a rejection device, and a control device. The alarm device is configured to issue an alarm signal. The rejection device is configured to reject the cut package 12 outside the operating channel. The control device is signal-connected to the detection device 3, the alarm device, and the rejection device and is configured to: in response to the rejection device's action information of rejecting the package 12 and in response to detection information indicating the presence of a positioning mark 120 at the location of any of the detection devices 3, cause the alarm device to issue an alarm signal.

[0059] The action information of the rejection device mentioned above can be obtained from the changes in the drive signal of the drive device of the rejection device, or from the detection information of external sensors corresponding to the rejection device, such as position detection sensors, displacement sensors, speed sensors, etc.

[0060] In the above embodiment, when the rejection device removes the cut package 12, and the detection information of the positioning mark 120 is present at the location of any detection device 3, it indicates that the package 12 may have failed to be cut and therefore failed to be unpacked. At this time, the unpacking device sends an alarm signal as a prompt, thereby timely restricting the actions of related execution components in subsequent processes and reducing the risk of errors in subsequent processes.

[0061] Some embodiments of this disclosure also provide a packaging line for tobacco products, including the unpacking equipment provided in the embodiments of this disclosure.

[0062] The packaging line for tobacco products provided by the embodiments of this disclosure has the advantages of the aforementioned unpacking equipment.

[0063] In some embodiments, the control device described above may be implemented as a general-purpose processor, a programmable logic controller (PLC), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic device, discrete gate or transistor logic device, discrete hardware component, or any suitable combination thereof for performing the functions described herein.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and not to limit them; although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this disclosure or equivalent substitutions can be made to some technical features, all of which should be covered within the scope of the technical solutions claimed in this disclosure.
