[0009] It is further defined that a first bearing is installed at the free end of the guide rod, and the first bearing is located in the first guide groove.

Such a structural design, in which the X-axis connecting rod, the Y-axis connecting rod and the Z-axis connecting rod are connected in sequence to form a connection assembly, makes the installation position of the second cylinder more flexible and more practical.

[0014] It is further defined that the guide member includes a guide frame, a guide block, a second bearing, a guide shaft, a second guide seat and a second linear bearing, the guide frame and the second guide seat are both fixedly connected to the mounting plate, the guide block is fixedly mounted on the Z-axis connecting rod, a second guide groove is provided on the guide frame, the second bearing is fixedly mounted on the guide block and slidably mounted in the second guide groove, the guide shaft is fixedly mounted on the Z-axis connecting rod and parallel to the second cylinder, the second linear bearing is fixedly mounted in the second guide seat, and the guide shaft is inserted into the second linear bearing.

[0020] It is further defined that the flat plate is provided with a third limiting column behind the support plate, and when the third push plate is not pushing the cigarette pack, the third limiting column rests against the back of the third push plate.

[0046] The elastic component 98 is a torsion spring, which has a simple structure, is easy to install and is highly practical.

[0047] The second motion mechanism is the second cylinder 205, and a connecting assembly is fixedly connected between the motion end of the second cylinder 205 and the second push plate 201.

The X-axis connecting rod 2010, the Y-axis connecting rod 209 and the Z-axis connecting rod 202 are connected in sequence to form a connecting assembly, so that the installation position of the second cylinder 205 can be more flexible and more practical.

[0049] The guide member includes a guide frame 203, a guide block 204, a second bearing 208, a guide shaft 2040, a second guide seat 207 and a second linear bearing 206. The guide frame 203 and the second guide seat 207 are both fixedly connected to the mounting plate 10. The guide block 204 is fixedly mounted on the Z-axis connecting rod 202.

The guide shaft 2040 is passed through the second linear bearing 206. Through the mutual cooperation between the guide block 204 and the second guide groove, and the mutual cooperation between the guide shaft 2040 and the second guide seat 207, the freedom of the second push plate 201 is limited, and the second push plate 201 and the connecting assembly are supported in the vertical direction, so that the second push plate 201 can only move horizontally left and right under the action of the second cylinder 205. The structure is simple and practical.

[0050] The third motion mechanism is a third cylinder 315. A connecting frame is fixedly connected between the third push plate 301 and the third motion mechanism. A transverse guide rod 314 parallel to the third cylinder 315 is fixedly installed on the connecting frame. A third guide seat 312 is also fixedly installed on the flat plate 311. A third linear bearing 313 is installed in the third guide seat 312. The transverse guide rod 314 is inserted in the third linear bearing 313. The third cylinder 315 is used as the third motion mechanism to realize the forward and backward pushing of the third push plate 301. The structure is simple and practical. The transverse guide rod 314 on the connecting frame cooperates with the third guide seat 312 on the flat plate 311 to limit the transverse movement of the third push plate 301 and form support for the connecting frame and the third push plate 301 in the vertical direction. It is practical.

[0051] The connecting frame includes a laterally arranged pushing frame 305 and a vertically arranged supporting frame 316, the two ends of the supporting frame 316 are respectively fixedly connected to the pushing frame 305 and the moving end of the third cylinder 315, the transverse guide rod 314 is fixedly installed on the supporting frame 316, the free end of the pushing frame 305 is hinged to the third push plate 301, the pushing frame 305 is fixedly installed with a supporting plate 303 behind the third push plate 301, the supporting plate 303 is installed with a spring 306 below the pushing frame 305, the free end of the spring 306 rests on the third push plate 301, and the third push plate 301 is in a state of tilting backward from bottom to top when the cigarette pack 1 is not pushed. The third push plate 301 is hinged with the push frame 305, and the spring 306 supports the lower part of the third push plate 301, so that the third push plate 301 is in a state of tilting backward from bottom to top before pushing the cigarette pack 1 on the flat plate 311. After the cigarette pack 1 is pushed into place, the reaction force applied to the third push plate 301 by the turnover box 2 through the cigarette pack 1 overcomes the prestress of the spring 306, so that the third push plate 301 becomes vertical, thereby completing the purpose of pushing the cigarette pack 1 in the flat plate 311 into the turnover box 2 and stacking the cigarette pack 1 vertically in the turnover box 2; during the pushing process, the back side of the third push plate 301 bears the dual force of the push frame 305 and the spring 306, so that during the pushing process, the cigarette packs 1 stacked on the flat plate 311 are in a state of tilting backward from bottom to top, avoiding the problem of the cigarette packs 1 on the flat plate 311 being scattered after shaking during the pushing process, and having strong practicality.

[0052] The support plate 303 is provided with a second limiting column 304 below the pushing frame 305. When the third push plate 301 is in a vertical state, the second limiting column 304 abuts against the back of the third push plate 301. The second limiting column 304 is used to limit the maximum clockwise inclination angle of the third push plate 301, thereby preventing the third push plate 301 from changing to a state of tilting forward from bottom to top during the process of pushing the cigarette pack 1 due to too small elastic force of the spring 306, thereby causing the cigarette packs 1 stacked on the flat plate 311 to fall forward, and the practicability is strong.

[0053] The cigarette pack storage 96 is tilted backward from bottom to top. Due to the tilt of the cigarette pack storage 96 and the tilt of the third push plate 301 in the initial state, after the cigarette pack 1 is pushed out of the cigarette pack storage 96 by the second push plate 201 and enters the flat plate 311 of the filling mechanism, the back side can be supported by the tilted third push plate 301, so that the placement is more stable and more practical.

[0054] The support plate 303 is provided with a first limiting column 302 above the pushing frame 305. When the third push plate 301 does not push the cigarette pack 1, the first limiting column 302 abuts against the back of the third push plate 301. The first limiting column 302 is used to limit the maximum counterclockwise inclination angle of the third push plate 301, so as to avoid the problem that the third push plate 301 tilts backward from bottom to top too much due to the excessive elastic force of the spring 306, and does not match the inclination angle of the cigarette pack library 96, and the practicability is strong.

[0055] The flat plate 311 is provided with a third limiting post 307 behind the supporting plate 303. When the third push plate 301 does not push the cigarette pack 1, the third limiting post 307 abuts against the back of the third push plate 301. The first limiting post 302 is used to limit the minimum counterclockwise inclination angle of the third push plate 301, so as to avoid the problem that the angle of the third push plate 301 tilting backward from bottom to top is too small due to the small elastic force of the spring 306, and the problem that the angle does not match the inclination angle of the cigarette pack library 96 is avoided, and the practicability is strong.

[0056] The first limiting column 302, the second limiting column 304 and the third limiting column 307 are all bolts. When installing the first limiting column 302, the second limiting column 304 and the third limiting column 307, it is only necessary to tighten them, and when adjusting the first limiting column 302, the second limiting column 304 and the third limiting column 307, it is only necessary to rotate the first limiting column 302, the second limiting column 304 and the third limiting column 307, which is convenient for installation and debugging and has strong practicality.

[0057] In this embodiment, before use, the turnover box 2 is placed in the bearing seat 309 so that the opening of the turnover box 2 faces the filling mechanism;

[0058] When using (such as Figure 2 , Figure 4 and Figure 5 As shown in the figure, the cigarette pack 1 conveyed by the upstream machine passes through the mounting plate 10 and enters the lower part of the one-way check mechanism and is located on the first push plate 103 under the restriction of the upstream guide rail 3. The first cylinder 106 drives the first push plate 103 to push upward, driving the cigarette pack 1 to move upward, pushing the one-way block 97 to enter the cigarette pack warehouse 96. The first cylinder 106 retracts. The cigarette pack 1 cannot fall downward under the action of the one-way block 97 and the elastic component 98 (torsion spring). The first cylinder 106 repeats the above steps to stack the cigarette packs 1 in the cigarette pack warehouse 96 until the proximity switch 95 senses the cigarette pack 1.

[0059] The proximity switch 95 transmits a signal to the electronic control system, which controls the operation of the second cylinder 205 (eg Figure 2 and Figure 3As shown), the second push plate 201 moves to the left, driving the cigarette packs 1 stacked in the cigarette pack library 96 to the flat plate 311, and the counting module counts the number of times the second cylinder 205 operates. During the pushing process, the cigarette packs 1 that arrive on the flat plate 311 at the back push the cigarette packs 1 that arrive in front;

[0060] When the counting module reaches a certain number of times, the electronic control system controls the third cylinder 315 to operate (such as Figure 2 and Figure 6 As shown), all cigarette packs 1 on the flat plate 311 are driven to move toward the turnover box 2 until the cigarette packs 1 enter the turnover box 2, and then the turnover box 2 loaded with the cigarette packs 1 is replaced by a new turnover box 2.

[0061] The above is a detailed introduction to an automatic cigarette packing device provided by the present invention. The description of the specific embodiment is only used to help understand the method and core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
