[0002] Cigarette packs are formed from die-cut cardboard and then folded and glued together to form boxes. When the number of cigarette packs is large, they are typically stacked and bundled into specific layers after die-cutting. These are then stacked on pallets for storage and transportation.

[0003] Cigarette pallet stacking is a highly repetitive and labor-intensive operation, typically performed manually. The palletizing process requires that the upper and lower layers of cigarette packs face different orientations. Automated palletizing presents significant difficulties in adjusting the pack's orientation, and conventional palletizing equipment lacks operational flexibility. Summary of the Invention

During the transfer process, the rotary drive mechanism adjusts the clamping mechanism to adapt to the placement angle of the pallet according to the orientation of the pallet. 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. The disordered cigarette pack palletizer of the present application can adapt to the disordered placement of pallets to a certain extent, and has the advantages of a high degree of automation and flexible palletizing operation.

[0015] The coordination of the transverse, longitudinal, and vertical drive mechanisms allows the clamping assembly to move omnidirectionally in both the horizontal and vertical directions, thereby meeting the horizontal and height changes of the palletizing position during the palletizing process. This also reduces the equipment installation height requirement and alleviates plant height restrictions.

[0042] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. 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

[0043] As shown in Figure 1 and Figure 2 , a cigarette package disorderly stacking machine comprises a rack 1, a feeding module 2 and a stacking module 3. The rack 1 comprises a feeding area 11 and a stacking area 12. The feeding area 11 is provided with a feeding platform. As shown in Figure 1 , Figure 2 , Figure 12 and Figure 13 , the stacking area 12 is provided with a plurality of support columns 13. Each of the support columns 13 encloses a stacking space. The stacking space is located on one side of the feeding platform. At least two adjacent support columns 13 form a tray loading and unloading channel 14. Figure 12 and Figure 13 , specifically, the lower end of the support column 13 is freely arranged. Correspondingly, the stacking space is directly arranged on the ground in the working state. The tray can be directly placed on the ground, which is convenient for the tray to enter and exit.

[0044] The tray loading and unloading channel 14 is used for feeding the tray 6 and feeding the completed stack. Since the stacking space is enclosed by the support columns 13, two support columns 13 can be reasonably selected as the boundaries of the tray loading and unloading channel 14 according to the layout requirements on the spot. The orientation of the tray loading and unloading channel 14 is more flexible.

[0045] As shown in Figure 1-Figure 5 , the feeding module 2 is arranged on the feeding platform of the feeding area 11. The feeding module 2 is provided with a feeding station.

[0046] As shown in Figure 6 and Figure 7 , the feeding module 2 comprises a feeding assembly 21 and a material arranging assembly 22. The feeding assembly 21 comprises a temporary storage mechanism and an indexing mechanism. The temporary storage mechanism is provided with a temporary storage station 211. The temporary storage station 211 is provided with a temporary storage stopper. The indexing mechanism comprises an indexing chuck 213 and an indexing driving member. The indexing driving member is used to drive the indexing chuck 213 to reciprocate between the temporary storage station 211 and the inlet end of the conveying unit.

[0047] As shown in Figure 6 and Figure 7 , specifically, the indexing driving member comprises an indexing support beam 215, a vertical indexing driving member 216, an indexing sliding block 214 and a horizontal indexing driving member. The indexing support beam 215 is horizontally arranged and movably connected to the rack 1. The vertical indexing driving member 216 is used to drive the indexing support beam 215 to move. The indexing sliding block 214 is slidably arranged on the indexing support beam 215. The horizontal indexing driving member is used to drive the indexing sliding block 214 to move.

[0048] As shown in Figure 6 and Figure 7 As shown, specifically, the indexing chuck 213 is disposed on an indexing slider 214. The indexing chuck 213 includes two clamping arms disposed in parallel, and the clamping arms are disposed in parallel below the indexing slider 214. The indexing chuck 213 also includes a driving member for driving the two clamping arms to move relative to each other.

[0049] like Figure 6 and Figure 7 As shown, the material sorting component 22 includes a material sorting conveying unit 221, an end positioning member 223 and a lateral sorting mechanism, and the end positioning member 223 is arranged near the output end of the conveying unit; the lateral sorting mechanism includes a sorting drive member 222 and two sorting blocks 224, and the two sorting blocks 224 are arranged on both sides of the conveying unit, and the sorting drive member 222 is used to drive the two sorting blocks 224 to move relative to each other.

[0050] The material sorting and conveying unit 221 can realize the horizontal conveying operation of the material pile, the end positioning member 223 can realize the positioning operation of the material pile, and the lateral sorting mechanism can realize the lateral orientation adjustment operation of the material pile, creating conditions for the stacking module 3 to accurately and reliably clamp the material pile.

[0051] The temporary storage mechanism can store a certain number of material piles. When the material sorting component 22 performs a lateral sorting operation 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.

[0052] like Figure 6 and Figure 7 As shown, the feeding module 2 also includes a feeding control assembly, which includes a feed sensor 212 and a material sorting sensor 225. The feed sensor 212 is located at the temporary storage station 211 and is used to determine whether there is a material pile at the temporary storage station 211, providing a basis for the operation of the indexing mechanism. There are at least two material sorting sensors 225, one of which is located at the inlet end of the material sorting conveying unit 221 to detect the material pile entering the material sorting assembly 22 and further record the number of material piles entering the material sorting assembly 22, and the other is located near the end positioning member 223 to detect whether the material pile has reached the end positioning member 223. The feed sensor 212 and material sorting sensor 225 can be photoelectric sensors. By setting the material sorting sensor 225, when 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.

[0053] like Figure 8 and Figure 9As shown, the palletizing module 3 includes a clamping assembly 31 and a palletizing drive assembly 32. The palletizing 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 palletizing area 12. The clamping assembly 31 includes a transition slider 325, a clamping seat 312, a rotation drive mechanism and a clamping mechanism. The transition slider 325 is connected to the palletizing drive assembly 32. The clamping seat 312 is rotationally connected to the transition slider 325, and the rotation drive mechanism is used to drive the clamping seat 312 to rotate around the vertical center line. The clamping mechanism includes a clamping drive 315 and two clamps 311. The two clamps 311 are arranged in parallel below the clamping seat 312. The clamping drive 315 is used to drive the two clamps 311 to move relatively closer or farther away.

[0054] like Figure 8 As shown, specifically, the stacking drive assembly 32 includes a transverse drive mechanism, a longitudinal drive mechanism, and a vertical drive mechanism. The vertical drive mechanism includes a transverse support beam 323 and a vertical drive member 321. The transverse support beam 323 is horizontally arranged and movably connected to the frame 1 in the vertical direction. The vertical drive member 321 is used to drive the transverse support beam 323 to move. The transverse drive mechanism includes a longitudinal support beam 324 and a transverse drive member 322. The longitudinal support beam 324 is horizontally arranged perpendicular to the transverse support beam 323 and movably arranged on the transverse support beam 323. The transverse drive member 322 is used to drive the longitudinal support beam 324 to move. The longitudinal drive mechanism includes a longitudinal drive member. 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.

[0055] By cooperating with the transverse, longitudinal, and vertical drive mechanisms, the clamping assembly 31 can be moved omnidirectionally in both the horizontal and vertical directions, thereby meeting the horizontal and height changes of the palletizing position during the palletizing process. This also reduces the height requirements for equipment installation and alleviates plant height restrictions.

[0056] Specifically, such as Figure 9 As shown, the two clamping plates 311 are respectively slidably connected to the clamping seat 312. The clamping driver 315 is connected to one of the clamping plates 311 and drives the clamping plate 311 to move. The clamping mechanism also includes a synchronization unit, which includes a synchronization gear 313 and two synchronization racks 314. The two synchronization racks 314 are respectively engaged with the synchronization gear 313. The synchronization gear 313 is rotationally connected to the clamping seat 312, and the synchronization racks 314 correspond to the clamping plates 311 and move synchronously.

[0057] 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.

[0058] Specifically, the palletizing module 3 also includes a palletizing control assembly, which includes a visual recognition unit. The visual recognition unit is positioned above the palletizing area 12 and has a downward detection direction. The palletizing control assembly is used to detect the position of the pallet in the palletizing area 12 and generate two-dimensional coordinates to provide a reference for the operation of the palletizing drive assembly 32.

[0059] During palletizing, a pallet 6 is placed in the palletizing area 12. Cigarette packs are fed into the feeding station of the feeding module 2 in a bundled pile. The clamping assembly 31 moves to the feeding station, where two clamping plates 311 grip the pile. The palletizing drive assembly 32 drives the clamping assembly 31 and the pile to rotate synchronously onto the pallet 6 in the palletizing area 12. During this rotation, the rotation drive mechanism adjusts the clamping mechanism to match the pallet's placement angle based on the orientation of the pallet 6. If the angle of the pile relative to the pallet needs to be adjusted, this can be accomplished during the rotation process.

[0060] like Figure 12-14 As shown, the pallet retaining assembly 15 is further included, which is detachably connected to the frame 1. The pallet retaining assembly 15 is disposed within the palletizing space and opposite the pallet loading and unloading channel 14. The pallet retaining assembly 15 can restrict the pallet to prevent it from shifting during palletizing. The removable configuration of the pallet retaining assembly 15 allows for flexible adjustment of its installation position according to the orientation of the pallet loading and unloading channel 14.

[0061] like Figure 14 Specifically, the tray limiting assembly 15 includes a mounting base 151 and two limiting sliders 152. The mounting base 151 is disposed on the frame 1. The limiting sliders 152 are slidably connected to the mounting base 151, and a locking unit is provided between the limiting sliders 152 and the mounting base 151. The two limiting sliders 152 are respectively provided with elastic limiting arms 153.

[0062] Further, such as Figure 1 and Figure 2 As shown, the frame 1 is also provided with a plate placement station, which is located on one side of the stacking area 12. Figure 10 and Figure 11As shown, the system further includes a separator feeding module 42, which includes a negative pressure adsorption unit 423 and a feeding drive mechanism. 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 materials, the separator feeding module 42 picks up the separator 5 from the plate placement station and automatically transfers it to the top of the material stack, realizing the automatic feeding operation of the separator 5.

[0063] like Figure 10 and Figure 11 As shown, specifically, the feed drive mechanism includes a main drive unit and a secondary drive unit. The negative pressure adsorption unit 423 is disposed on the transition slider 325. Specifically, the negative pressure adsorption unit 423 is connected to the transition slider 325 via the secondary drive unit. The stacking drive assembly 32 serves 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. The secondary drive unit includes a horizontal telescopic drive member 421 and a vertical telescopic drive member 422. The horizontal telescopic drive member 421 is mounted on the transition slider 325 and is used to drive the vertical telescopic drive member 422 and the negative pressure adsorption unit 423 to move horizontally. The vertical telescopic drive member 422 is used to drive the negative pressure adsorption unit 423 to move vertically. When the clamping assembly 31 performs a 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 sufficient space for the movement of the negative pressure adsorption unit 423.

[0064] Specifically, such as Figure 12 and Figure 13 As shown, the plate placement station is provided with a plate placement bracket 41, and the frame 1 is provided with a partition lifting mechanism 43, which is used to drive the plate placement bracket 41 to move up and down. The plate placement bracket and the feeding area 11 are opposite to the stacking area 12 on the left and right.

[0065] The height of the partition bracket is automatically adjusted according to the increase of the stacking height and the decrease of the number of partitions. The negative pressure adsorption unit 423 is set on the transition slider 325, and the negative pressure adsorption unit 423 can be driven by the stacking drive component 32 to achieve indexing.

[0066] Specifically, such as Figure 12 and Figure 13 As shown, the partition bracket is set between two adjacent support columns 13. When the pallet and the stack of materials need to be loaded and unloaded between the two support columns 13 corresponding to the partition bracket, the partition bracket can be raised to a specific height through the partition lifting mechanism 43 to leave space for the pallet.

[0067] The cigarette pack disorderly palletizer of the present application can adapt to the disordered placement of pallets to a certain extent, and has the advantages of a high degree of automation and flexible palletizing operation.

[0068] A cigarette pack palletizing method, using the above-mentioned cigarette pack random palletizing machine;

[0069] At least the following steps are included:

[0070] S1. Feeding: Cigarette packs are fed into the temporary storage station 211 of the feed assembly 21 in bundles. The indexing mechanism transfers the stack of cigarettes one by one to the material handling and conveying unit, which drives the stack of cigarettes into the feeding station of the feeding area 11. Simultaneously, pallets 6 are loaded from the pallet loading and unloading channel 14 into the palletizing area 12. The pallet limiting assembly 15 limits the position of the pallet 6. The palletizing control assembly detects the pallet's position and generates position information for the pallet 6.

[0071] S2. Retrieving materials: The stacking drive assembly 32 drives the clamping assembly 31 to transfer to the feeding station, and the clamping assembly 31 clamps the cigarette pack.

[0072] S3. Rotation: The palletizing drive assembly 32, under the guidance of the palletizing control assembly, drives the clamping assembly 31 and the cigarette pack to rotate synchronously onto the pallet 6 in the palletizing area 12. During the rotation process, the rotary drive mechanism drives the clamping seat 312 to rotate relative to the transition slide 325 to the appropriate angle based on the orientation of the pallet 6.

[0073] S4. Palletizing: The clamping assembly 31 releases the cigarette packs, completing the palletizing operation of the current stack. Determine whether palletizing of the current layer is complete: if not, repeat steps S2 to S4; if palletizing of the current layer is complete, proceed to step S5.

[0074] S5. Partition feeding: The feeding drive mechanism works to drive the negative pressure adsorption unit 423 to move to the plate placement station. After the negative pressure adsorption unit 423 absorbs the partition 5, the feeding drive mechanism drives the negative pressure adsorption unit 423 and the partition 5 to move above the material stack to complete the partition 5 feeding operation.

[0075] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
