Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0058] The embodiment of the present application discloses a cigarette stacking device, such as Figure 1 and Figure 2 As shown, it includes a mounting frame 1, and the mounting frame 1 includes a mounting base 11; a first pushing member 21 is slidably connected to the mounting base 11, and the first pushing member 21 has a first position, and the first pushing member 21 includes a first side surface 211 and a second side surface 212 facing away from the first side surface 211. When the first pushing member 21 is in the first position, a supporting limit column 3 is respectively provided at both ends of the width direction of the first side surface 211, and the width of the first pushing member 21 is less than the distance between the two supporting limit columns 3, so that the first pushing member 21 can push and return to the reciprocating linear motion in the vertical direction of the line connecting the two supporting limit columns 3; a limiting baffle 4, the limiting baffle 4 includes a fixing portion 42 and a limiting portion 41, and when the first pushing member 21 is in the first position, the limiting portion 41 and the first pushing member 2 1 is located on both sides of the line between the two supporting and limiting columns 3, so that a cigarette stacking space 51 is formed between the limiting portion 41, the two supporting and limiting columns 3 and the first pushing member 21, and the fixing portion 42 is connected to the first driving member 43, and the first driving member 43 is used to drive the limiting portion 41 to reciprocate along the direction of the line between the two supporting and limiting columns 3 to open or close the cigarette stacking space 51, so that the first pushing member 21 can push the cigarettes in the cigarette stacking space 51 out of the cigarette stacking space 51; a second pushing member 22 is also provided on the mounting base 11, and a cigarette stacking area 52 is formed between the second pushing member 22 and the limiting portion 41. When the cigarette stacking space 51 is opened, the first pushing member 21 can push the cigarettes in the cigarette stacking space 51 out of the cigarette stacking space 51 to the cigarette stacking area 52.

[0059] When the first pushing member 21 is in the first position, the first pushing member 21, the two supporting limit columns 3 and the limiting portion 41 of the limit baffle 4 form a cigarette stacking space 51, and the cigarettes slide from the cigarette entrance 511 into the cigarette stacking space 51, so that the cigarettes are stacked in order from top to bottom. When the cigarette stacking space 51 is opened, the first pushing member 21 pushes the stacked cigarette pile 81 in the cigarette stacking space 51 as a whole to the cigarette stacking area 52, which greatly reduces the problem of missing cigarettes caused by cigarette stacking.

[0060] In one embodiment, if Figure 3-5 As shown, the cigarette holder 6 is also included. The cigarette holder 6 includes a supporting portion 61 and a connecting portion 62. The supporting portion 61 extends into the cigarette stacking space 51 through the gap between the support limit column 3 and the first pusher 21 in the first position, and is used to support the cigarettes transported from the conveying structure. The connecting portion 62 is connected to a lifting structure 63. The lifting structure 63 includes a first ball screw 631. The first ball screw 631 is provided with a plurality of lifting gears. The lifting distance between adjacent lifting gears is the size of the width of a cigarette. When the conveying structure transports a cigarette into the cigarette stacking space 51, the supporting portion 61 of the cigarette holder 6 will support the cigarette. When the conveying structure transports the next cigarette, the supporting portion 61 of the cigarette holder 6 will drop the width of a cigarette, so that the other cigarette drops to the same position as the previous cigarette, so as to ensure the accuracy of cigarette transportation and avoid the occurrence of missing cigarettes.

[0061] As a specific implementation, the first ball screw 631 is provided with five lifting gears, so that the cigarette cartons are stacked along the width direction of the cigarette cartons, and every five cigarette cartons form a cigarette stack 81 .

[0062] In a preferred embodiment, Figure 6 As shown, the supporting portion 61 includes two symmetrically arranged supporting plates 611, and the supporting plates 611 and the connecting portion 62 form a U-shaped structure. When the first pushing member 21 is in the first position, the two symmetrically arranged supporting plates 611 extend into the cigarette stacking space 51 through the gap between the first pushing member 21 and the two supporting limit columns 3, respectively. The connecting portion 62 is arranged on the outside of the second side surface 2112 of the first pushing member 21 to ensure that the falling cigarette remains horizontal. When the first pushing member 21 is in the first position, the U-shaped structure of the supporting plates 611 and the connecting portion 62 can prevent the supporting plates 611 from preventing the first pushing member 21 from being pushed.

[0063] As a specific implementation method, Figure 4As shown, the limiting part 41 and the fixing part 42 of the limiting baffle 4 are L-shaped, and the fixing part 42 is arranged on the outside of the side of the supporting limiting column 3 away from the cigarette stacking space 51; the first driving member 43 is a pushing cylinder, and the height of the limiting part 41 is not less than the height of the cigarette stack 81. When the cigarette stacking space 51 is full of cigarettes, the pushing cylinder drives the limiting part 41 through the fixing part 42 to move away from each other in the direction of the vertical line between the two supporting limiting columns 3 to open the cigarette stacking space 51, so that the first pushing member 21 pushes out the cigarette stack 81 in the cigarette stacking space 51 and pushes it to the second pushing member 22, and then returns to its original position, and the pushing cylinder drives the limiting part 41 through the fixing part 42 to move closer to each other in the direction of the line between the two supporting limiting columns 3 to close the cigarette stacking space 51 and stack the next stack of cigarettes.

[0064] In a preferred embodiment, Figure 4 As shown, the distance between the two supporting limit columns 3 is the length dimension of the cigarette carton 82; the distance between the limit portion 41 and the first pushing member 21 in the first position is the thickness dimension of the cigarette carton, so that the cigarette carton stacking space 51 is adapted to the size of the cigarette carton as much as possible to ensure that the cigarette carton is neatly stacked in the cigarette carton stacking space 51.

[0065] To adjust the size of the area occupied by the cigarette stacking area 52 to accommodate different numbers of cigarette stacks 82, such as Figure 4 As shown, a first sliding member is provided at the bottom of the second pusher 22, and a second sliding member slidably connected to the first sliding member is provided on the mounting base 11 to adjust the distance between the second pusher 22 and the limiting portion 41. As an embodiment, the first sliding member is a first slider 222, and a first slide groove is provided on the first slider 222.

The first slider 222 is connected to a first lead screw 223, and the first lead screw 223 is arranged parallel to the first guide rail 12. The first lead screw 223 is connected to a first driving assembly 91, which is used to drive the first slider 222 to drive the second pusher 22 to approach or move away from the limiting portion 41.

[0066] A second slider 212 is connected to the bottom of the first pushing member 21. A second slide groove is provided on the second slider 212. The second slide groove can be used in conjunction with the first guide rail 12. The second slider 212 is connected to a second lead screw 213 (not shown in the figure). The second lead screw 213 is arranged parallel to the first guide rail 12. The second lead screw 213 is connected to a second driving assembly 92 for driving the second slider 212 to drive the first pushing member 21 to perform reciprocating linear motion along the first guide rail 12.

[0067] As an implementation method, Figure 1As shown, the first pushing member 21 includes a first pushing plate 211, and the second pushing member 21 includes a second pushing plate 221 arranged parallel to the first pushing plate 211, and a cigarette stacking area 52 is formed between the second pushing plate 221 and the limiting portion 41; when the first pushing member 21 is in the first position, a cigarette stacking space 51 is formed between the limiting portion 41, the two supporting limiting columns 3 and the first pushing plate 211.

[0068] During the pushing process, when the first push plate 211 pushes forward the thickness of a stack of cigarette cartons, the corresponding second push plate 221 retreats the thickness of a stack of cigarette cartons to ensure that the cigarette cartons stack 81 is neatly stacked into a cigarette cartons stack 8, and finally a 5X10 or 5X5 cigarette cartons stack is completed. The cigarette cartons stack 8 is then pushed into the turnover box 102 through the stacking assembly 101 to proceed to the next process.
