[0024] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without carrying out creative work are within the scope of protection of the present disclosure.
[0025] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.
[0026] In the description of the present disclosure, it needs to be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific positional relationship.
[0027] like Figure 1 and Figure 2 As shown, the present disclosure provides a tobacco slice conveying device, comprising:
[0028] A slicer 1, configured to cut the cigarette pack into cigarette slices;
[0029] A conveying component 2 is provided downstream of the slicer 1, and includes a conveyor 21 and two protective side plates 22. The conveyor 21 is configured to convey tobacco slices, and the two protective side plates 22 are provided on both sides of the conveyor 21 along the width direction, and the protective side plates 22 extend along the length direction of the conveyor 21; and
[0030] The detection component 3 is configured to detect the height of the tobacco sheet in the conveying state, and the detection component 3 includes a transmitting device 31 and a receiving device 32, which are respectively arranged on the two protective side plates 22 and are arranged opposite to each other in the length direction.
[0031] The slicer 1 cuts the cigarette pack into individual slices along the vertical direction after the outer packaging is removed, and the thickness of each slice needs to be as consistent as possible, all within the preset thickness range, and the thickness of each slice in each area is kept uniform. When the slices are transported by the conveyor 21, compared with the cutting state, the slices are flipped 90° and placed on the conveyor 21, so the height of the slice in the transport state is its thickness.
[0032] This embodiment can prevent the scattered tobacco shreds from falling during the conveying process by setting a protective side plate 22 on the side of the conveyor 21, and can prevent the tobacco shreds from falling into the conveyor, thereby improving the operational reliability of the conveying component 2, and can prevent the tobacco shreds from falling on the ground, keeping the site clean. In addition, by installing a detection component 3 on the protective side plate 22, the height dimension (i.e., thickness) of the tobacco slices in the conveying state can be detected in real time, and the situation that the thickness of the tobacco slices does not meet the process requirements can be discovered in time, so that timely investigation and adjustment can be carried out, so as to achieve the purpose of real-time detection and early warning of the thickness of the tobacco slices, and effectively prevent the uneven thickness of the tobacco slices from affecting the subsequent processes.
[0033] In some embodiments, the detection component 3 includes a distance measuring grating sensor, which is configured to obtain the thickness of the tobacco sheet by measuring the distance at which the tobacco sheet blocks the grating in real time. This type of sensor has a high detection accuracy. In addition, infrared radiation sensors, laser sensors, etc. can also be selected.
[0034] In some embodiments, Figure 2 As shown, the tobacco slice conveying device also includes a bracket 8 and a cover plate 7 made of transparent material. A through groove 221 is opened on each protective side plate 22 from the top, and the through groove 221 extends along the height direction. The through groove 221 is covered by the cover plate 7, and the transmitting device 31 and the receiving device 32 are both installed on the outer side of the cover plate 7 through the bracket 8.
[0035] The through slot 221 may be an elongated slot and sealed with a transparent cover plate 7 to prevent tobacco from leaking through the gap between the cover plate 7 and the protective side plate 22 and adhering to the detection component 3, thereby ensuring the detection accuracy of the detection component 3.
[0036] In this embodiment, a through groove 221 is provided on the protective side plate 22 and is closed by a transparent cover plate 7. The detection component 3 can be arranged on the outer side of the protective side plate 22 to prevent tobacco shreds on the conveyor 21 from adhering to the detection component 3, keep the detection surface clean, and improve the detection accuracy and precision; and for tobacco slices whose height is lower than the protective side plate 22, light can also be passed through the cover plate 7 for detection, thereby improving the detection adaptability to slices of different thicknesses; in addition, the through groove 221 is covered by the cover plate 7, which can prevent tobacco shreds from leaking through the gap between the cover plate 7 and the protective side plate 22 and adhering to the detection component 3, thereby ensuring the detection accuracy of the detection component 3.
[0037] In some embodiments, Figure 2As shown, the bracket 8 is detachably mounted on the protective side plate 22 through the fastener 6, and the fastener 6 is located on both sides of the through slot 221. The bracket 8 is located on the outer side of the cover plate 7.
[0038] The bracket 8 of this embodiment is detachably mounted on the protective side plate 22. When the cover plate 7 is worn or the cleanliness is poor, the bracket 8 can be removed to replace or clean the cover plate 7, thereby ensuring the detection accuracy of the detection component 3 during long-term use.
[0039] In some embodiments, the bottom of the through slot 221 is not higher than the top surface of the thinnest tobacco sheet to be transported. This embodiment enables the detection range of the detection component 3 to cover slices of all thicknesses formed in actual production.
[0040] In some embodiments, the tobacco slice conveying device further includes a bracket 8 and a protective cover made of a transparent material, and the transmitting device 31 and the receiving device 32 are both mounted on the inner side of the protective side plate 22 through the bracket 8, and are protected by the protective cover mounted on the protective side plate 22. The protective cover can be mounted on the protective side plate 22, or installed together with the detection component 3.
[0041] In this embodiment, the detection component 3 is installed on the inner side of the protective side plate 22, and there is no need to groove the protective side plate 22. It is easy to add the detection component 3 to the original system, and the detection component 3 is protected by a transparent protective cover to prevent tobacco from adhering to the detection component 3, thereby ensuring the detection accuracy of the detection component 3.
[0042] In some embodiments, the tobacco slice conveying device further includes an alarm, which is configured to send out an alarm indication signal when the detection component 3 detects that the height of the tobacco slice exceeds a preset range and lasts for a preset time. For example, the alarm may be an audible and visual alarm, etc. The alarm may be provided in the operating station.
[0043] This embodiment can output alarm information in time when the thickness of the tobacco sheet exceeds the limit by setting an alarm, so as to remind the maintenance worker to check and adjust, so as to achieve the purpose of real-time monitoring and early warning of the thickness of the tobacco sheet, and effectively prevent the influence of uneven thickness of the tobacco sheet on the process.
[0044] In some embodiments, along the length direction, the size of the through slot is not less than the size of the detection surface of the emitting device and the receiving device. This ensures that the light emitted by the emitting device 31 passes through the through slot 221 and can be received by the receiving device 32 in the slot width direction when not blocked by the smoke sheet, thereby improving the accuracy of detection.
[0045] In some embodiments, the tobacco slice conveying device further includes a display 5 configured to display in real time the height information of the tobacco slices detected by the detection component 3 and / or display alarm information.
[0046] This embodiment facilitates real-time monitoring of the thickness of the tobacco sheet. The tobacco sheet thickness data is displayed in real time on the display 5 of the on-site operation station, which is convenient for the operator to monitor. When the thickness of the tobacco sheet exceeds the limit, an alarm message is output to the display 5 to remind the maintenance worker to check and adjust, thereby achieving the purpose of real-time monitoring and early warning of the tobacco sheet thickness, and effectively preventing the influence of uneven tobacco sheet thickness on the process.
[0047] In addition, the tobacco slice conveying device also includes a PLC controller 4, which is electrically connected to the detection component 3 and is used to obtain the detection value of the detection component 3 and process and convert it to obtain the real-time thickness data of the tobacco slice.
[0048] The tobacco slice conveying device disclosed in the present invention can monitor the thickness of the tobacco slices in real time by providing a tobacco slice thickness monitoring device, and promptly discover the situation that the thickness of the tobacco slices does not meet the process requirements. At the same time, the thickness of the tobacco slices is displayed in real time on the display screen of the operation station. If the thickness exceeds the preset range, including the situation that the thickness exceeds the upper limit or is less than the lower limit, an alarm reminder is output in time.
[0049] Secondly, the present disclosure provides a tobacco production system, including the tobacco slice conveying device of the above embodiment.
[0050] After the slicer 1 performs the slicing operation, the tobacco production system can detect the thickness of the tobacco slices in real time, and promptly discover that the thickness of the tobacco slices does not meet the process requirements, so as to make timely inspections and adjustments, thereby achieving the purpose of real-time detection and early warning of the thickness of the tobacco slices, and effectively preventing the uneven thickness of the tobacco slices from affecting subsequent processes.
[0051] The above are merely exemplary embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
