[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, 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 application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the application. Meanwhile, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to actual proportional relationships. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0028] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, and the spatially relative descriptions used here are interpreted accordingly.

[0029] In the related art, when the cigarette packs are transported to the entrance of the packaging machine, the cigarette packs are placed in the following postures during the movement: Figure 1 As shown, multiple stacks of cigarette packs are arranged along the moving direction, each stack includes two cigarette packs stacked in the thickness direction of the cigarette pack, and each cigarette pack is in a lying state, wherein the drawstring of the cigarette pack (not shown in the figure) extends out relative to the cigarette pack body along the moving direction, so there is no problem of the drawstring being bent by the cover plate.

[0030] However, in the process of producing side-open cigarette packs, the placement of the cigarette packs changes, such as Figure 3 and 4 As shown, the cigarette pack is changed from the original lying state to the standing state, causing the drawstring to extend in the height direction Z relative to the cigarette pack body. If the original cover plate is still used for production, the drawstring will be bent by the cover plate, affecting the production quality.

[0031] For this purpose, refer to Figure 2 , 5~7, some embodiments of the present application provide a cigarette packing machine system, which includes a packing machine 20, an inlet channel 10 and a cover plate 30. The packing machine 20 has an inlet for receiving a cigarette pack A. The inlet channel 10 is docked with the inlet for the cigarette pack A to move thereinto. The cover plate 30 is connected to the packing machine 20, and the cover plate 30 is arranged above the inlet channel 10 in the height direction Z. A groove 31 is arranged on the cover plate 30. The extension direction of the groove 31 is consistent with the extension direction of the inlet channel 10. A drawstring B is arranged on the cigarette pack A. The drawstring B extends in the height direction Z relative to the cigarette pack A. In the process of the cigarette pack A moving toward the inlet in the inlet channel 10, the groove 31 accommodates at least a portion of the drawstring B extending in the height direction Z relative to the cigarette pack A.

[0032] By providing the groove 31 on the cover plate 30 , the groove 31 avoids the drawstring B, thereby effectively reducing the risk of the drawstring B being bent by the cover plate 30 , maintaining the drawstring quality in good condition, and thus improving the production quality.

[0033] In some embodiments, the cigarette pack A has an upper surface A1 and a lower surface A2 that are parallel to each other. During the movement of the cigarette pack A, the lower surface A2 is in contact with the channel surface of the inlet channel 10 (the channel surface is the plane in the inlet channel 10 for carrying the cigarette pack A). The upper surface A1 is in contact with the surface of the cover plate 30 facing the channel surface. The groove 31 accommodates the portion of the draw strap B that extends in the height direction Z relative to the upper surface A1.

[0034] refer to Figure 3 and 8 When the cigarette package A is in the inlet channel 10, the upper surface A1 of the cigarette package A contacts the bottom surface of the cover plate 30. During the movement of the cigarette package A, the bottom surface of the cover plate 30 applies friction to the upper surface A1 of the cigarette package A, which can improve the movement stability of the cigarette package A and reduce the risk of the cigarette package A falling. It is worth noting that the upper surface A1 of the cigarette package A and the lower surface of the cover plate 30 are only slightly in contact and not tightly fitted, so as to avoid excessive sliding friction that hinders the movement of the cigarette package A.

[0035] The depth of the groove 31 is slightly greater than the length of the drawstring B extending relative to the upper surface A1 , so that the groove 31 can completely accommodate the extended portion of the drawstring B, thereby protecting the drawstring B from being bent.

[0036] refer to Figure 5 In some embodiments, the cover plate 30 comprises a rectangular long plate. The length direction of the cover plate 30 is consistent with the length direction of the inlet passage 10. The width direction of the cover plate 30 is consistent with the width direction of the inlet passage 10. In the width direction of the cover plate 30, the groove 31 is close to the edge of the cover plate 30.

[0037] Specifically, the width of the entrance channel 10 is roughly equal to the width of the cigarette package A, so that the two side edges of the entrance channel 10 can limit the cigarette package A from both sides, thereby improving the movement stability of the cigarette package A and reducing the risk of tipping over, and the width of the cover plate 30 is also roughly equal to the width of the cigarette package A, so that almost the entire upper surface A1 of the cigarette package A can contact and generate friction with the bottom surface of the cover plate 30, thereby further improving the movement stability of the cigarette package A.

[0038] In some embodiments, the cover plate 30 is provided with a mounting through hole 32 penetrating in the thickness direction of the cover plate 30. The cigarette packing machine system further includes a detection device (not shown in the figure) installed in the mounting through hole 32. The detection device is used to detect whether the cigarette pack A is tipped over.

[0039] By setting up a detection device, it can be ensured that the cigarette package A enters the entrance of the packaging machine 20 in an upright position. When the cigarette package A falls over, the detection device can detect it in time and remind the staff to deal with it, thereby improving the reliability of the production process and improving production quality.

[0040] refer to Figure 6 In some embodiments, the cover plate 30 is further provided with a side opening 33. The side opening 33 extends inside the cover plate 30. One end of the side opening 33 is connected to the inner wall surface of the mounting through hole 32, and the other end of the side opening 33 is connected to the outer surface of the cover plate 30. The side opening 33 is used to install a fastener to fasten the detection device.

[0041] Specifically, the side opening 33 is a straight hole and extends along the width direction of the cover plate 30. The inner wall of the side opening is provided with a thread. The fastener may include a top screw. By screwing the top screw, the end of the top screw abuts against the detection device to achieve the fastening of the detection device.

[0042] refer to Figure 4 In some embodiments, the inlet passage 10 is used to convey cigarette pack groups. Each cigarette pack group includes a plurality of cigarette packs A arranged in sequence along the moving direction of the cigarette packs A in the inlet passage 10.

[0043] The entrance channel 10 inputs multiple cigarette packs A into the entrance of the packaging machine 20 at one time, and the draw straps B of the multiple cigarette packs A in the cigarette pack group are all accommodated by the grooves 31, ensuring that the draw straps B of the multiple cigarette packs A are not bent by the cover plate 30, thereby improving both production efficiency and production quality.

[0044] In some embodiments, a cigarette pack group includes ten cigarette packs A.

[0045] refer to Figure 2In some embodiments, the cigarette packing machine system includes a conveying device 40 and a detection device. The inlet channel 10 is connected to the end of the conveying device 40. The conveying device 40 is used to convey cigarette packs A into the inlet channel 10 to form a cigarette pack group in the inlet channel 10. In the moving direction, the detection device corresponds to the position of the frontmost row of cigarette packs A in the cigarette pack group to detect whether the frontmost row of cigarette packs A are overturned.

[0046] In some embodiments, the detection device includes a photoelectric detector. The cigarette pack packaging machine system also includes a controller, and the photoelectric detector is connected to the controller signal. When the cigarette pack A passes under the photoelectric detector in a normal posture (i.e., upright state), the photoelectric detector can detect the existence of the cigarette pack, and the controller deems that the cigarette pack A has not fallen, and the cigarette pack packaging machine system operates normally. If the cigarette pack A falls and passes under the photoelectric detector in a falling posture, the distance between the cigarette pack A and the photoelectric detector in the height direction Z becomes larger, resulting in the photoelectric detector being unable to detect the existence of the cigarette pack A. The controller deems that the cigarette pack A has fallen, and controls the cigarette pack packaging machine system to shut down.

[0047] It is worth noting that the photoelectric detector only needs to detect whether the cigarette pack A in the front row of a cigarette pack group has fallen over. If the cigarette pack A in the front row has not fallen over, it can be considered that all the cigarette packs in the cigarette pack group have not fallen over. If the cigarette pack A in the front row has fallen over, the machine needs to be stopped for processing.

[0048] In some embodiments, the conveying device 40 comprises a conveyor belt configured to convey the cigarette packets to the inlet passage 10 .

[0049] The following is a brief description of the process of forming a cigarette pack group in the entrance channel 10. After the first cigarette pack A is transported into the entrance channel 10 by the conveyor belt, it is no longer affected by the conveyor belt. Under the action of inertia, it slides a certain distance in the moving direction in the entrance channel 10 and stops. Subsequently, the second cigarette pack A enters the entrance channel 10 and slides and collides with the first cigarette pack A, causing the two cigarette packs A to fit each other and move a certain distance in the moving direction, until the last cigarette pack A enters the entrance channel 10 and collides and fits with the adjacent front row of cigarette packs to form a complete cigarette pack group. At this time, the position of the front row of cigarette packs A in the cigarette pack group in the entrance channel 10 just corresponds to the detection device, which facilitates the detection device to detect whether the front row of cigarette packs A has fallen.

[0050] In order to improve the adaptability of the cigarette packing machine system to the production of cigarette packs of different specifications, refer to Figure 5 and 6 In some embodiments, the mounting through hole 32 comprises an elongated hole. The elongated hole extends along the moving direction of the cigarette pack A in the inlet passage 10. The position of the detection device in the moving direction is adjustable through the mounting through hole 32.

[0051] Since the moving direction is consistent with the length direction of the cover plate 30, the installation through hole 32 extends along the length direction of the cover plate 30. When the specifications of the produced cigarette packs change, the position of the frontmost cigarette pack A in a cigarette pack group changes in the inlet channel 10. At this time, it is necessary to adjust the installation position of the detection device so that the position of the detection device corresponds to the position of the frontmost cigarette pack A. Specifically, loosen the top screw and then adjust the position of the detection device in the installation through hole 32. After the adjustment is completed, screw the top screw so that the end of the top screw abuts the detection device, and the position adjustment of the detection device is completed. The adjustment process is simple and easy to operate.

[0052] In some embodiments, the detection device has an adjustment range of 5 mm.

[0053] In some embodiments, the cigarette packing machine system further includes a pushing device (not shown in the figure). The pushing device is used to push the cigarette pack group to move into the entrance in the entrance channel 10. When the detection device does not detect that the cigarette pack A has fallen, the pushing device is activated and applies a thrust to the cigarette pack A in the last row of the cigarette pack group. When the detection device detects that the cigarette pack A has fallen, the pushing device is not activated.

[0054] Specifically, the pushing device is connected to the controller signal, and when the detection device does not detect that the cigarette pack A has fallen, the controller controls the pushing device to start. When the detection device detects that the cigarette pack A has fallen, after the staff has finished processing the cigarette pack group, the controller controls the pushing device to start again, and pushes the cigarette pack group into the packaging machine 20. After the pushing device pushes the entire cigarette pack group into the entrance of the packaging machine 20, the conveying device 40 conveys a new cigarette pack A to the entrance channel 10. After a new cigarette pack group is formed in the entrance channel 10, the detection device detects whether the cigarette pack has fallen, and the pushing device performs corresponding actions according to the detection result of the detection device. The specific principle is as above and will not be repeated. Based on this, not only can the risk of the cigarette pack being squeezed by the pushing device continuing to push the cigarette pack to move in the state of the cigarette pack falling be reduced, but also the risk of the pushing device being damaged by the excessive reaction force of the cigarette pack in this situation can be reduced. In other words, the pushing device is only started when it is determined that there is no falling cigarette pack in the entrance channel 10, which protects both the cigarette pack A and the pushing device and improves the production safety of the cigarette pack packaging machine system.

[0055] In some embodiments, the pushing device includes a driving device and a push rod. The controller is connected to the driving device by signal, and the driving device is used to drive the push rod to push the cigarette pack group to move. The driving device includes a cylinder.

[0056] In some embodiments, the cover plate 30 further includes a mounting hole 34 , which is disposed on an upper surface of the cover plate 30 . The cover plate 30 is connected to the frame through the mounting hole 34 , so that the cover plate 30 can be fixed above the inlet passage 10 .

[0057] In some embodiments, the cigarette pack A comprises a side-opening cigarette pack.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present application can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present application, which should be included in the scope of the technical solution for protection in the present application.
