[0003] On this basis, the applicant designed this solution for the output station and the transfer device to improve the efficiency and stability of cigarette stacking. Summary of the Invention

[0004] Therefore, the present invention provides a cigarette stack palletizing device and a stacking and palletizing method thereof, which solve the problem of insufficient stability in the cigarette palletizing process.

[0005] To achieve the above object, the present invention is realized by the following technical solutions:

[0006] A cigarette stack palletizing device includes a frame, on which there is a conveying device for conveying cigarette packs and a cage truck for docking the cigarette packs output by the conveying device. The cage truck has a side wall end with three closed ends, a receiving opening end, and a bottom wall end for bearing weight.

[0007] Define the conveying direction of the conveying device as the X direction, the vertical direction as the Z direction, and the direction perpendicular to the X direction and the Z direction as the Y direction; on the frame, there is a double-shaft moving platform for the two-way movement of the conveying device along the Y direction and the Z direction.

[0008] One end of the bottom wall of the cage cart, which is away from the conveying device, is hinged to the frame. One side of this end of the bottom wall is provided with an ejecting driving member for rotating the cage cart by an angle along the frame. Both ends of the ejecting driving member are respectively hinged to the end of the bottom wall and the frame to realize the tilting action of the cage cart.

[0009] When the cigarette packets are output by the conveying device, the cage cart tilts in the direction away from the output end of the conveying device to receive the cigarette packets and make the cigarette packets fit on the side wall end.

[0010] Preferably, at the lower end of the output end of the conveying device, there is a telescopic plate for supporting the output cigarette packets. When the cigarette packets are output, the telescopic plate extends and reaches into the cage cart to support the cigarette packets. When the output cigarette packets are in the cage cart, the telescopic plate retracts to make the cigarette packets fall into the cage cart.

[0011] Preferably, at the output end of the conveying device, there is a guiding plate for guiding the telescopic plate. When the telescopic plate extends, it is in a parallel state with the end of the bottom wall of the cage cart.

[0012] Preferably, inside the cage cart, there is a supporting member for supporting the telescopic plate.

[0013] Preferably, the conveying device is a plurality of synchronously driven conveying rollers and their transmission components.

[0014] Preferably, the conveying device is a conveyor belt assembly and its transmission components.

[0015] A stacking and palletizing method for the cigarette stack according to the above cigarette stack stacking and palletizing device includes the following steps:

[0016] S1. The cigarette packets are conveyed at intervals by the conveying device, successively being cigarette packets m1, m2... mn, and the conveying device gives each cigarette packet a linear velocity along the X direction.

[0017] S2. Drive the ejecting driving member to make the cage cart in an inclined state.

[0018] S3. Adjust the double-axis moving platform to make the output end of the conveying device located at the bottom position of the cage cart, and make the Z-direction height of the output end of the conveying device greater than the height of the bottom wall end of the opening side of the cage cart.

[0019] S4. Send the cigarette packet m1 from the conveying device end into the cage cart, and make the cigarette packet m1 fall naturally and fit on the bottom wall end and the side wall end of the cage cart.

[0020] S5. Adjust the double-axis moving platform to make the output end of the conveying device located above the cigarette packet m1, and make the Z-direction height of the output end of the conveying device greater than the Z-direction high point of the cigarette packet m1.

[0021] S6. Feed the cigarette pack m2 into the cage car from the conveying device end, allowing the cigarette pack m2 to fall naturally and adhere to the top of the cigarette pack m1 and the side wall end of the cage car;

[0022] S7. Repeat the above steps S5 and S6 until the current cage car is full, completing the stacking and palletizing of the cage cars.

[0023] Preferably, between the above steps S3 and S4, there is also a step S31: extend the telescopic plate at the output end of the conveying device to receive the cigarette pack and make the cigarette pack in an inclined state.

[0024] By adopting the foregoing technical solution, the beneficial effects of the present invention are as follows:

[0025] This technical solution designs the structure for the process of feeding cigarette packs into the cage car. During the transfer of cigarette packs, the cage car for receiving materials is correspondingly inclined. After the cigarette pack is output from the conveying device, it falls, and gradually adheres to the side wall end and the bottom wall end of the cage car during the falling process. When repeating this process to complete the stacking and palletizing of multiple cigarette packs, the semi-automatic sorting of multiple cigarette packs can be achieved through this principle, making the stacking and palletizing of cigarette packs in the cage car more regular, and it is not easy to have the situation of the stack collapsing due to improper conveying. Precise position adjustment is performed on the stack during output, and there will be no large-drop falling, ensuring the structural stability of the cigarette packs during the output process, avoiding the occurrence of cigarette pack breakage and deformation during the transfer process, improving the integrity of the cigarette packs after palletizing, and reducing the probability of rework due to cigarette pack breakage during the palletizing process.

[0030] The following will specifically describe the embodiments of the present invention in detail, so as to fully understand how the present invention uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.

[0031] Refer to Figure 1 and Figure 2, A cigarette stack palletizing device, including a frame. On the frame, there is a conveying device 1 for conveying cigarette packs, and a cage car 2 for docking the cigarette packs output by the conveying device 1. The cage car 2 has a side wall end 2a with three ends closed, a receiving opening end, and a load-bearing bottom wall end 2b.

[0032] Define the conveying direction of the conveying device 1 as the X direction, the vertical direction as the Z direction, and the direction perpendicular to the X direction and the Z direction as the Y direction. On the frame, there is a double-axis moving platform 4 for the conveying device 1 to move in both the Y direction and the Z direction. Among them, the double-axis moving platform 4 can refer to CN 116443592 A in this prior art and will not be described in detail here. In this structure, the conveying device 1 can perform palletizing and stacking along the Z axis in one cage car 2 under the action of the double-axis moving platform 4. Or multiple cage cars 2 can be arranged in the Y-axis direction, so that a single conveying device 1 can convey and stack the cigarette packs of multiple cage cars 2.

[0033] The bottom wall end 2b on the side of the cage car 2 away from the conveying device 1 is hinged on the frame (i.e., the frame hinge end a). On one side of the bottom wall end 2b, there is an ejecting driving part for making the cage car 2 rotate an angle along the frame. The two ends of the ejecting driving part are respectively hinged to the bottom wall end 2b and the frame to realize the tilting action of the cage car 2 (i.e., the rotating hinge end b).

[0034] When the cigarette packs are output by the conveying device 1, the cage car 2 tilts in the direction away from the output end of the conveying device 1 to receive the cigarette packs and make the cigarette packs fit on the side wall end 2a. This technical solution designs the structure for the process of the cigarette packs being conveyed into the cage car 2. During the transfer process of the cigarette packs, the cage car 2 for receiving the materials is tilted accordingly. After the cigarette packs are output by the conveying device 1, they fall, and gradually fit on the side wall end 2a and the bottom wall end 2b of the cage car 2 during the falling process. When repeating this process to complete the stacking and palletizing of multiple cigarette packs, the semi-automatic sorting of multiple cigarette packs can be realized through this principle, making the stacking and palletizing of the cigarette packs in the cage car 2 more regular, and not easily causing the collapse of the stack due to improper conveying. The precise position adjustment of the stack during output will not result in a large drop, ensuring the structural stability of the cigarette packs during the output process, avoiding the occurrence of cigarette pack breakage and deformation during the transfer process, improving the integrity of the cigarette packs after palletizing, and reducing the probability of rework due to cigarette pack breakage during the palletizing process.

[0035] On the basis of the above structure, further improvements can be made. Structurally, a telescopic plate 3 is provided at the lower end of the output end of the conveying device 1 for supporting the output cigarette pack; when the cigarette pack is output, the telescopic plate 3 extends out and extends into the cage trolley 2 to support the cigarette pack; when the output cigarette pack is in the cage trolley 2, the telescopic plate 3 retracts to allow the cigarette pack to fall into the cage trolley 2. The telescopic plate 3 is connected to a driving member for driving its reciprocating extension and retraction, which can be a linear motion mechanism such as an oil cylinder or an air cylinder; the surface of the telescopic plate 3 is a smooth surface to minimize the friction between the cigarette pack and it, ensure the smoothness of the relative movement between the telescopic plate 3 and the cigarette pack, and reduce the wear on the contact surface of the cigarette pack.

[0036] Structurally, a guide plate 31 for guiding the telescopic plate 3 is provided at the output end of the conveying device 1, and a guide groove is provided on the guide plate 31. When the telescopic plate 3 is extended, it is parallel to the bottom wall end 2b of the cage trolley 2, that is, when extended, according to the arrangement of the guide groove, the telescopic plate 3 is also inclined with respect to the horizontal plane, and then during the output process of the cigarette pack, the cigarette pack is received and made to be inclined, and one side of the cigarette pack moves toward the side wall end 2a of the cage trolley 2, thereby further improving the stability of the conveying process and ensuring the structural integrity and beauty of the cigarette pack.

[0037] It should be noted that during the stacking process, the displacement of the Z axis needs to refer to the height of the cigarette pack, so that after the telescopic plate 3 is extended, the distance between its bottom and the cigarette pack is appropriate (that is, it can avoid mutual collision and not be too high), so that the cigarette pack located on the top falls to a smaller height and is not prone to deviation or tilt;

[0038] In the present technical solution, the conveying device 1 is a plurality of synchronously driven conveying rollers 11 and their transmission components; the transmission component is a roller synchronization structure well known to those skilled in the art, such as a synchronous belt and a corresponding synchronous wheel arranged on the conveying roller 11, and no limitation is made here; similarly, the conveying device 1 can also be a traditional conveyor belt assembly and its transmission assembly.

[0039] On the basis of the above structure, a support member for supporting the telescopic plate 3 can be provided inside the cage trolley 2. The support member can be provided at both ends inside the cage trolley 2 or on the cage trolley 2 at the end where the support plate extends out. The support plate is erected after the support plate is extended out. The support member can increase the service life of the original telescopic plate 3 and form a structural support for the support plate after it is extended out, so as to avoid deformation of the support plate or inadequate output after long-term use.

[0040] On the basis of the above, the process of stacking and palletizing is clarified.

[0041] That is, a stacking and stacking method according to the above-mentioned cigarette stacking and stacking device, such as Figure 3 As shown, the following steps are included:

[0042] S1, cigarette packs are transported at intervals by the conveying device 1, which are cigarette packs m1, m2...mn in sequence, and the conveying device 1 imparts a linear velocity along the X direction to each cigarette pack; the velocity is imparted so that the cigarette packs have an outward inertia at the output end so as to be transported into the cage vehicle 2 and maintain the angle in the air during the transport process without falling and flipping;

[0043] S2, driving the ejection drive member to make the cage trolley 2 tilted, and the tilt angle can be adjusted according to the above-mentioned linear speed to meet the tilt state of the cage trolley 2 as much as possible during the falling process of the cigarette packs after being output;

[0044] S3, adjust the biaxial mobile platform 4 so that the output end of the conveying device 1 is located at the bottom of the cage 2, and the Z-direction height of the output end of the conveying device 1 is greater than the height of the bottom wall end 2b of the opening side of the cage 2. At this time, it is necessary to ensure that the height between the output end and the opening end of the cage 2 is appropriate, and the distance between the X-direction and the Z-direction is sufficient;

[0045] The process of outputting cigarette packs also includes step S31: extending the telescopic plate 3 at the output end of the conveying device 1 to receive the cigarette packs, and making the cigarette packs in an inclined state; the telescopic plate 3 is extended and also in an inclined state, so that the angle of the cigarette packs can be adjusted in this process to adapt to the inclined angle of the cage vehicle 2, so as to achieve a smoother transition;

[0046] S4, delivering the cigarette pack m1 from the end of the conveying device 1 into the cage vehicle 2, so that the cigarette pack m1 naturally falls and adheres to the bottom wall end 2b and the side wall end 2a of the cage vehicle 2;

[0047] S5, adjusting the biaxial movable platform 4 so that the output end of the conveying device 1 is located above the cigarette pack m1, and the Z-direction height of the output end of the conveying device 1 is greater than the Z-direction high point of the cigarette pack m1;

[0048] S6, delivering the cigarette pack m2 from the end of the conveying device 1 into the cage vehicle 2, so that the cigarette pack m2 naturally falls and adheres to the top of the cigarette pack m1 and the side wall end 2a of the cage vehicle 2;

[0049] S7. Repeat the above steps S5 and S6 until the current cage car 2 is full, and the stacking and palletizing of the cage car 2 is completed.

[0050] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
