It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example

[0026] like Figure 1 and Figure 2 As shown, a cigarette pack random stacking machine includes a frame 1, a feeding module 2 and a stacking module 3. The frame 1 includes a feeding area 11 and a stacking area 12. The feeding area 11 is provided with a feeding platform, such as Figure 1 , Figure 2 , Fig.12 and Fig.13 As shown, the stacking area 12 is provided with a plurality of support columns 13, and a stacking space is enclosed between each support column 13. The stacking space is located on one side of the feeding platform, and a pallet loading and unloading channel 14 is provided between at least two adjacent support columns 13. Fig.12 and Fig.13 As shown, specifically, the lower end of the support column 13 is freely arranged, and the corresponding stacking space is directly arranged on the ground in the working state, and the pallet can be directly placed on the ground to facilitate the entry and exit of the pallet.

[0027] The pallet loading and unloading passage 14 is used for the pallet 6 to be brought in and the palletized material to be sent out. Since the palletizing space is enclosed by the support columns 13, two of the support columns 13 can be reasonably selected as the boundaries of the pallet loading and unloading passage 14 according to the on-site layout requirements, and the orientation of the pallet loading and unloading passage 14 is more flexible.

[0028] like Figure 1-Figure 5 As shown, the feeding module 2 is arranged on the feeding platform of the feeding area 11, and a feeding station is provided on the feeding module 2.

[0029] like Figure 6 and Figure 7 As shown, the feeding module 2 includes a feeding assembly 21 and a material sorting assembly 22. The feeding assembly 21 includes a temporary storage mechanism and a transfer mechanism. The temporary storage mechanism is provided with a temporary storage station 211, and the temporary storage station 211 is provided with a temporary storage block. The transfer mechanism includes a transfer chuck 213 and a transfer drive. The transfer drive is used to drive the transfer chuck 213 to reciprocate between the temporary storage station 211 and the inlet end of the conveying unit.

[0030] like Figure 6 and Figure 7 As shown, specifically, the transfer drive member includes a transfer support beam 215, a vertical transfer drive member 216, a transfer slider 214 and a horizontal transfer drive member. The transfer support beam 215 is horizontally arranged and movably connected to the frame 1 up and down. The vertical transfer drive member 216 is used to drive the transfer support beam 215 to move.

[0034] The temporary storage mechanism can store a certain number of material piles. When the material sorting component 22 performs lateral sorting operations on the material pile, or the clamping component 31 clamps the material pile at the feeding station, the transfer mechanism stops working, and the fed material pile can be temporarily stored in the temporary storage mechanism. While ensuring continuous feeding, it does not interfere with the work of the material sorting component 22 and the clamping mechanism, and plays a good rhythm balancing function.

[0035] like Figure 6 and Figure 7 As shown, the feeding module 2 also includes a feeding control component, and the feeding control component includes a feeding sensor 212 and a material sorting sensor 225.

Through the setting of the material sorting sensor 225, after the material pile on the material sorting conveying member reaches a certain number, the stacking module 3 station can be controlled to achieve simultaneous stacking of multiple material piles, thereby improving efficiency.

[0036] like Figure 8 and Fig. 9 As shown, the stacking module 3 includes a clamping assembly 31 and a stacking drive assembly 32. The stacking drive assembly 32 is used to drive the clamping assembly 31 to move in the horizontal and vertical directions and to transfer between the feeding station and the stacking area 12.

The transition slider 325 is movably arranged on the longitudinal support beam 324. The longitudinal drive member is used to drive the transition slider 325 to move.

[0038] Through the cooperation of the transverse drive mechanism, the longitudinal drive mechanism and the vertical drive mechanism, the clamping assembly 31 can be moved in all directions in the horizontal and vertical directions, so as to meet the changes in the horizontal direction and height of the stacking position during the stacking process. At the same time, the requirements for the installation height of the equipment can be reduced, and the height limit of the factory building can be reduced.

[0039] Specifically, Fig. 9 As shown, the two clamping plates 311 are respectively slidably connected to the clamping seat 312, and the clamping drive 315 is connected to one of the clamping plates 311 and drives the clamping plate 311 to move.

[0040] Through the linkage of the synchronization unit, the synchronization of the movement between the two clamping plates 311 can be ensured, thereby ensuring the reliability of clamping the material pile.

[0041] Specifically, the palletizing module 3 further includes a palletizing control component, which includes a visual recognition unit, which is arranged above the palletizing area 12 and has a detection direction downward. The palletizing control component is used to detect the position of the pallet in the palletizing area 12 and generate a two-dimensional coordinate to provide a reference for the operation of the palletizing drive component 32.

[0042] When performing the palletizing operation, the pallet 6 is placed in the palletizing area 12, and the cigarette packs are fed into the feeding station of the feeding module 2 in the form of a bundled material pile. The clamping assembly 31 moves to the feeding station, and the two clamping plates 311 clamp the material pile. The palletizing drive assembly 32 drives the clamping assembly 31 and the material pile to be synchronously transferred to the pallet 6 in the palletizing area 12. During the transfer process, the rotating drive mechanism adjusts the clamping mechanism to rotate and adapt to the placement angle of the pallet according to the orientation of the pallet 6. When the placement angle of the material pile relative to the pallet needs to be adjusted, the adjustment can also be completed during the transfer process.

[0043] like Figure 12-14 As shown, further, it also includes a pallet limiting assembly 15, and the pallet limiting assembly 15 is detachably connected to the frame 1. The pallet limiting assembly 15 is arranged in the palletizing space and is arranged opposite to the pallet loading and unloading channel 14. The pallet limiting assembly 15 can impose certain restrictions on the pallet to prevent the pallet from shifting during the palletizing process. The detachable setting of the pallet limiting assembly 15 can flexibly adjust the installation position according to the setting direction of the pallet loading and unloading channel 14.

[0044] like Fig.14 As shown, specifically, the tray limiting assembly 15 comprises a mounting seat 151 and two limiting sliders 152, the mounting seat 151 is arranged on the frame 1, the limiting slider 152 is slidably connected with the mounting seat 151, and a locking unit is arranged between the limiting slider 152 and the mounting seat 151. The two limiting sliders 152 are respectively provided with elastic limiting arms 153.

[0045] Further, such as Figure 1 and Figure 2 As shown, the frame 1 is also provided with a plate placing station, and the plate placing station is located on one side of the stacking area 12. Fig.10 and Fig.11 As shown, it also includes a partition feeding module 42, which includes a negative pressure adsorption unit 423 and a feeding drive mechanism, and the feeding drive mechanism is used to drive the negative pressure adsorption unit 423 to reciprocate between the plate placement station and the stacking area 12. After completing the stacking operation of a layer of material piles, the partition feeding module 42 works to pick up the partition 5 from the plate placement station and automatically transfer it to the top of the material pile, so as to realize the automatic operation of feeding the partition 5.

[0046] like Fig.10 and Fig.11As shown, specifically, the feed drive mechanism includes a main drive unit and a sub-drive unit, the negative pressure adsorption unit 423 is arranged on the transition slider 325, specifically, the negative pressure adsorption unit 423 is connected to the transition slider 325 through the sub-drive unit, and the stacking drive assembly 32 is used as the main drive unit of the feed drive mechanism, and is used to drive the large-scale movement of the negative pressure adsorption unit 423.

When the clamping assembly 31 performs stacking operation, the auxiliary drive unit drives the negative pressure adsorption chuck to retract to a specific position near the transition slider 325 to avoid interference with the indexing, clamping and rotational movements of the clamping assembly 31. During the partition feeding operation, the clamping assembly 31 is first rotated to a suitable angle to leave enough space for the movement of the negative pressure adsorption unit 423.
