[0024] 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.

[0027] refer to Figures 1 to 3 Some embodiments of the present application provide a cigarette pack extraction device for extracting a single cigarette pack A from a plurality of stacked cigarette packs A and delivering it to the next process. The cigarette pack extraction device comprises a suction device 1, a conveying device 2 and a guide member 3. The suction device 1 is used to suck from a plurality of cigarette packs A and drive a single cigarette pack A to move a first stroke along a first direction X to separate from the remaining cigarette packs. The conveying device 2 is disposed at the end of the first stroke, and is used to drive the cigarette pack A to move a second stroke along a second direction Y to the next process when the cigarette pack arrives at the conveying device 2. The first direction X and the second direction Y form an angle. The guide member 3 is disposed at the intersection of the first stroke and the second stroke, and is configured to guide and limit the cigarette pack A when the cigarette pack A changes from moving in the first stroke to moving in the second stroke.

[0028] Specifically, a plurality of cigarette packs A are stacked and arranged on the beam. The first stroke refers to the displacement of the cigarette pack A from its initial arrangement position on the beam to a position where it can be driven by the conveying device 2. The second stroke refers to the displacement of the cigarette pack A from the end of the first stroke to the next process. The conveying device 2 includes a conveyor belt and a lug arranged on the conveyor belt, the conveyor belt is located above the cigarette pack A in the height direction, and the lug moves synchronously with the conveyor belt. The position of the lug on the conveyor belt is constructed so that when the cigarette pack A moves to the end of the first stroke, the lug is located at the rear side of the cigarette pack A, and then the lug pushes the cigarette pack A to move along the second direction Y from the rear side of the cigarette pack A when the conveyor belt moves.

[0029] Under normal circumstances, the cigarette pack A does not contact the guide member 3 during the movement in the first stroke and the second stroke, or in other words, maintains a certain distance from the guide member 3. Only in special circumstances, for example, when the volume of some cigarette packs is larger than that of normal cigarette packs (cigarette packs are usually formed by folding cigarette pack paper, and glue is pasted on the cigarette pack paper to enhance the stability after folding into a cigarette box, but the cigarette pack still has a certain risk of expansion or expansion), such cigarette packs with abnormal volume will contact the guide member 3 at the guide member 3. If the guide member 3 is not provided, such cigarette packs will touch the structural members in the environment during the movement and become skewed, so that the position where the lug acts on the cigarette pack deviates from the normal position. Due to the push of the lug, the lug may squeeze the cigarette pack, which may damage the cigarette pack on the one hand, and on the other hand, the cigarette pack may detach from the lug and stay near the end of the first stroke, blocking the cigarette pack subsequently brought out by the suction device 1; or, there are factors such as the suction device 1 not being stable enough to adsorb cigarette pack A and the suction of cigarette pack A driving cigarette pack A to move too fast, which may also cause the cigarette pack A to be unable to smoothly enter the second stroke and get blocked near the guide member 3.

[0030] By providing the guide member 3, when the moving direction of the cigarette package A changes, it can play a guiding and limiting role for the cigarette package A that expands in volume, thereby ensuring that the cigarette package A has a correct posture when it reaches the end of the first stroke and smoothly passes to the next process, reducing the blockage of the cigarette package A and damage to the cigarette package A, thereby improving the production quality.

[0031] In some embodiments, the first direction X is perpendicular to the second direction Y. The first direction X is the transverse direction, and the second direction Y is the longitudinal direction. This arrangement helps to arrange the various components in the cigarette pack extraction device, making the layout more compact.

[0032] In some embodiments, the guide member 3 is rotatably arranged. When the cigarette pack A is extracted, the guide member 3 is rotated to reduce damage to the cigarette pack A when the cigarette pack A presses the guide member 3 .

[0033] When the guide member 3 is squeezed by the cigarette pack A, it rotates at a small angle and does not deflect over a large range, which helps to reduce the blockage of the cigarette pack A. It is also helpful to detect the deflection angle of the guide member 3 to know whether the process of outputting the cigarette pack A is normal, which is conducive to regulating the production process.

[0034] refer to Figure 2 and 3In some embodiments, the guide member 3 includes a first guide section 31 and a second guide section 32. The first guide section 31 extends from the end of the first stroke along the first direction X toward the remaining cigarette packs. The second guide section 32 extends from the end of the first stroke along the second direction Y toward the end of the second stroke. The first guide section 31 and the second guide section 32 are transitionally connected through a transition plane P. The extension direction of the transition plane P is at an angle to both the first direction X and the second direction Y.

[0035] If the first guide section 31 and the second guide section 32 are directly connected, the connection between the two will present a sharp angle, and when the cigarette pack A with expanded volume passes through the guide member 3, the connection between the first guide section 31 and the second guide section 32 may scratch the cigarette pack. By setting the transition plane P, the transition from the first guide section 31 to the second guide section 32 is gentler, which helps to improve the guiding effect of the cigarette pack A with expanded volume and reduce scratches on the cigarette pack A.

[0036] In some embodiments, the cigarette pack extraction device further comprises a frame. The frame is used to accommodate a plurality of cigarette packs A. One end of the first guide section 31 close to the remaining cigarette packs is rotatably connected to the frame. When the cigarette pack A moves, when the cigarette pack A squeezes the guide member 3, the guide member 3 rotates to reduce damage to the cigarette pack A.

[0037] The frame provides a mounting position for the guide member 3. The end of the first guide segment 31 is used as a rotation connection position to connect it to the frame. Compared with setting other positions of the guide member 3 to be rotationally connected to the frame, it can have a greater torque when the cigarette pack A contacts and squeezes the guide member 3, which helps to drive the guide member 3 to rotate and improve the guide limit effect and the blockage detection effect.

[0038] refer to Figure 3 In some embodiments, the end of the first guide segment 31 has a mounting site C for being connected to the frame via a hinge device.

[0039] In some embodiments, the guide member 3 further includes an extended guide segment 33. The extended guide segment 33 is connected to the end of the second guide segment 32 and extends along the second direction Y.

[0040] The extended guide section 33 further extends toward the end of the second stroke, thereby improving the guiding effect of the guide member 3 on the cigarette pack in the second direction Y, and making the movement of the cigarette pack along the second direction Y more stable and reliable.

[0041] In some embodiments, a groove is provided on the surface of the second guide section 32. The groove extends from the connection between the second guide section 32 and the transition plane P along the second direction Y to the end of the second guide section 32. At least part of the extended guide section 33 extends into the groove, and the rest of the extended guide section 33 is located outside the groove. In other words, at least part of the extended guide section 33 overlaps with the second guide section 32 in the second direction Y, and the second guide section 32 and the extended guide section 33 are connected by providing a connector at the overlapping section of the two to improve the stability of the connection between the two.

[0042] Furthermore, a recessed area is provided on the surface of the portion of the extended guide section 33 extending into the groove, and the connecting member includes a bolt, which is arranged in the recessed area. The bolt passes through the extended guide section 33 and the second guide section 32 in the first direction X to achieve connection of the overlapping portion of the extended guide section 33 and the second guide section 32. By providing the recessed area on the surface of the extended guide section 33, space is reserved for the arrangement of the bolt, so that the end of the bolt does not exceed the surface of the extended guide section 33, thereby improving the guiding effect of the guide member 3 on the cigarette pack A and reducing scratches on the cigarette pack A.

[0043] In some embodiments, the cigarette pack extraction device further comprises an alarm device, which sends an alarm signal when the guide member 3 rotates. This helps to promptly notify the staff when the guide member 3 rotates due to cigarette pack blockage, thereby improving the stability of the production process.

[0044] In some embodiments, when the alarm device is triggered, the cigarette pack extraction device is shut down, which helps the staff to detect and debug the equipment in time.

[0045] In some embodiments, the triggering conditions of the alarm device can be set. For example, when the rotation amplitude of the guide member 3 is less than the set value, it indicates that the guide member 3 has a small range of deflection. It may be that the cigarette pack touches the guide member, or it is caused by other circumstances, and no blockage has occurred. At this time, the alarm device does not need to alarm to remind the staff to pay attention; when the rotation amplitude of the guide member 3 is greater than the set value, it indicates that the guide member 3 has a larger range of deflection. It may be that the cigarette pack hits the guide member 3 with a large force, or it is caused by a blockage. At this time, the alarm device triggers an alarm signal to remind the staff to pay attention.

[0046] refer to Figure 3 In some embodiments, the cigarette pack extraction device further includes an elastic member 4. The elastic member 4 is connected between the frame and the guide member 3. When the guide member 3 rotates, the elastic member 4 is compressed. The cigarette pack A squeezes the guide member 3 to deflect, causing the elastic member 4 to be compressed by the guide member 3. When the cigarette pack A is separated from the guide member 3, the elastic member 4 is reset, driving the guide member 3 to reset as well, so that the guide member 3 can continue to play a guiding and limiting role in the process of extracting the next cigarette pack A, thereby improving the ability of sustainable work.

[0047] In some embodiments, the elastic member 4 includes a spring.

[0048] In some embodiments, when the cigarette pack A changes to move along the second direction Y, the conveying device 2 is configured to drive the cigarette pack A to move in a manner such that the posture of the cigarette pack A does not change.

[0049] Specifically, the cigarette package A is a rectangular parallelepiped, and the pair of parallel planes formed by the length and height of the cigarette package A are called the front surface and the rear surface, the pair of parallel planes formed by the length and width of the cigarette package A are called the upper surface and the lower surface, and the pair of parallel planes formed by the height and width of the cigarette package A are called the left end surface and the right end surface. Figure 1 As shown, the lug of the conveying device 2 acts on the right end surface of the cigarette pack A, as shown in FIG. Figure 2 As shown, the suction device 1 acts on the front surface of the cigarette pack A. First, the suction device 1 absorbs the front surface of the cigarette pack A, driving the cigarette pack A to move along the first direction X to the end of the first stroke (i.e. Figure 1 At this time, the lug of the conveying device 2 acts on the right end surface of the cigarette pack A, driving the cigarette pack A to move to Figure 1 In the position shown by the solid line on the left side, during the whole process, the front surface of the cigarette pack A always keeps the same direction and does not change.

[0050] Compared to changing the orientation of the front surface of the cigarette package A, for example, from the initial orientation facing the end of the first stroke to facing the end of the second stroke, the risk of damage to the cigarette package A due to collision with structural parts in the environment during the posture change of the cigarette package A can be reduced. It also helps to ensure that the contact position of the lug with each cigarette package A is roughly the same, thereby improving the stability of the cigarette package A moving along the second direction Y.

[0051] In some embodiments, the suction device 1 is used to generate negative pressure to absorb the cigarette pack A closest to the end of the first stroke among the multiple cigarette packs. That is, the suction device 1 sucks out one cigarette pack A at a time, and when the cigarette pack A is driven to move to the end of the first stroke, the negative pressure of the suction device 1 is reduced to separate from the front surface of the cigarette pack A. At this time, the cigarette pack A moves along the second direction Y under the action of the conveying device 2.

[0052] In some embodiments, the suction device 1 includes a cylinder and a suction cup. The suction cup is arranged at the output end of the cylinder. The cylinder is extended or retracted to make the suction cup approach or move away from the cigarette pack on the beam. The suction cup is used to generate negative pressure to adsorb the cigarette pack A.

[0053] Some embodiments of the present application also provide a packaging machine, comprising the cigarette pack extraction device as described above.

[0054] 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.
