the stack shape is four layers, each layer and second layer have 10 cigarettes respectively, and be upright state, and third layer, four layers have 4 cigarettes respectively, and the cigarette is the tie state.

When the third layer of cigarette pieces horizontally pass through the belt conveyor 401, the posture adjusting robot 402 does not act, and the finished cigarette pieces enter the horizontal layer tray assembly 501 in a horizontal state to complete tray assembly. The back auxiliary positioning plate 707 remains stationary, and the lateral positioning plate 703 and the back positioning plate 705 continue to extend to the preset positions.

The shelf reciprocating cylinder 708 contracts to drive the shelf 709 to horizontally move towards the flat-layer tray assembly 501 along the preset slide rail until the shelf completely covers the second layer of finished cigarettes on the tray 901 and slightly contacts the flat-layer tray assembly 501.

The pushing robot 701 pushes the third layer of finished cigarettes 101 in the horizontal state after the assembly to the shelf 709.

After the pushing robot 701 is pushed to the right position, the pushing robot returns to the initial position, the shelf 709 is pulled away under the action of the shelf reciprocating cylinder 708 and is blocked by the positioning plate 705, and the finished product cigarette assembly on the upper portion of the shelf is fully contacted with the second layer of finished product cigarettes on the tray 901 by a small drop, so that the third layer of tray assembly is completed.

The elevator roller conveyor 602 is lowered until the upper surface of the third layer of cigarettes on the pallet 901 is 4mm to 6mm, for example 5mm, below the loading surface of the flat stack tray assembly 501. During the period, the two lateral positioning plates 703, the back positioning plate 705 and the back auxiliary positioning plate 707 are still in the extending state to ensure the shape of the combined cigarette in the third layer.

When the fourth layer cigarette is flatly laid through the belt conveyor 401, the posture adjusting robot 402 does not act, and the finished cigarette enters the flat layer tray assembly 501 in a flatly laid state to complete tray assembly. The back auxiliary positioning plate 707 extends to slightly contact the third layer of flat cigarette, and the side positioning plate 703 and the back positioning plate 705 are kept still.

The shelf reciprocating cylinder 708 contracts to drive the shelf 709 to horizontally move towards the flat-layer tray assembly 501 along a preset slide rail until the shelf completely covers the third layer of finished cigarettes on the tray 901 and slightly contacts the flat-layer tray assembly 501.

The pushing robot 701 pushes the fourth layer of finished cigarettes 101 in the assembled flat state horizontally onto the shelf 709.

After the pushing robot 701 is pushed to the right position, the pushing robot returns to the initial position, the shelf 709 is drawn away under the action of the shelf reciprocating cylinder 708 and is blocked by the back positioning plate 705, and the finished product cigarette assembly on the upper portion of the shelf is fully contacted with the third layer of finished product cigarettes on the tray 901 by a small drop, so that the fourth layer of the tray is completed.

Step B9, after the completion of the palletizing of the multi-layer assembly, the lateral positioning plate 703, the back positioning plate 705 and the back auxiliary positioning plate 707 are reset along the slide rails under the driving of the respective corresponding driving cylinders, the multi-layer assembly and the tray 901 of the finished cigarette palletized by the elevator roller conveyor 602 are lowered until the object carrying surfaces of the elevator roller conveyor 602 are flush with the object carrying surfaces of the first chain conveyor 601 and the second chain conveyor 601 at the output end of the cigarette stack, so that the tray 901 after the palletizing is completed is output by the second chain conveyor 603.

Step B10, when the second chain conveyor 603 outputs the trays after the grouping, the RFID reader 604 is used to write the information related to the finished cigarettes on the tray 901 into the RFID chip at the bottom of the tray.

When the system finishes 30 piled third layer trays or finishes 28 piled fourth layer trays, the lateral positioning plate 703, the back positioning plate 705 and the back auxiliary positioning plate 707 are reset along the slide rails under the driving of the respective driving cylinders. The lifting roller conveyor 602 carries the cigarette carton and the pallet 901 to descend until the carrying surfaces of the cigarette carton and the pallet are flush with the carrying surfaces of the first chain conveyor 601 and the second chain conveyor 603. When the tray 901 after the grouping is completed is output from the system by the chain conveyor 603, the RFID reader 604 writes the relevant information into the RFID chip on the bottom of the tray 901. By this time, the single set of disk operations is finished.

Because the information such as the 'engineering code No. 1' of the finished cigarette is read and recorded when the finished cigarette passes through the photoelectric switch 301, and the flat-layer tray assembly 501 completes the flat-layer tray assembly according to the preset rule, the accurate position of a certain cigarette in the stack after the finished tray assembly can be accurately inquired subsequently.

According to the efficient flexible layer coding method for the finished cigarette, provided by the embodiment of the invention, the finished cigarette is input and verified; combining a plurality of finished cigarette pieces into a single-layer combined body according to a preset rule; combine into the multilayer assembly with a plurality of individual layer assemblies to output the multilayer assembly, can realize the automatic pile up neatly of arbitrary specification dysmorphism piece cigarette and deploy fast, solve the circulation smoke box and fall the condition that damages the strip cigarette unusually in the stacking process, the flow is clear, reliable and stable, it is convenient to maintain.
