Description

Pallet unit pallet removing and layering and stacking method, system and using method

Technical Field

The invention relates to the technical field of integral loading of integrated unit cargoes, in particular to a method, a system and a using method for removing trays and layering and stacking tray packaging units.

Background

According to the national standard, the definition of unit cargoes is: a group of goods or packages are assembled together by one or more means to form an integral unit for easy handling, transportation, stacking and storage. The definition of the pallet container unit is: and the unit cargoes and the tray form a whole. The package assemblies are stacked on a pallet with appropriate securement for mechanical handling and shipping. According to the definition above, unit loads are the entire stack of units on a pallet without a pallet.

At present, in the logistics operation at home and abroad, the unitized logistics technology of the pallet container unit has been widely applied, such as in the automatic production and storage system of factories, and the unitized logistics automation operation carried out by relying on standard pallets already covers the whole flow of the logistics in the factories.

However, in the handling and transporting links of product circulation, especially in long-distance transportation, export transportation and logistics transportation business requiring high actual load rate and low transportation cost, low energy consumption and low pollution of vehicles and containers, if the handling and transporting operation is performed by adopting a unitized logistics technology mode of pallet container units, the problems of low actual load rate of vehicles, high pallet cost or difficult recovery and the like exist, and the problems of greatly increasing transportation cost and pallet cost, increasing energy consumption, increasing pollution and the like are caused. So far, in order to save the logistic cost, most large-scale automatic production enterprises and small and medium-sized enterprises can use manpower to load and unload the products one by one without a tray to transport the products when the products are delivered out of the warehouse and transported, and the tray unitization operation is interrupted.

However, the manual handling of goods one by one has a number of drawbacks, mainly: the labor consumption is high, the logistics system efficiency is low, the operation quality is poor, the damage rate of goods is high, the product image and the enterprise image are affected, and the logistics system cannot adapt to the greatly increased business requirements of production and sales and the like.

However, the adoption of manual loading and unloading is a non-trivial choice for enterprises. Because the manual loading and unloading operation of sacrificing the operation efficiency and the operation quality is carried out one by one, the actual loading rate of the vehicle or the container can be improved, the difficult problems of tray cost or recovery are avoided, and a large amount of transportation and tray cost are saved.

In the logistics transportation business of the unitized logistics technology mode of the pallet container unit, the widely existing pain points and defects of the transportation operation mode with the pallet or the bottlenecks and defects of the transportation operation mode without the pallet and the manual one-by-one loading and unloading operation mode are caused to form trouble to the logistics industry for a long time and continuously, and the consumption reduction and the efficiency improvement of social logistics activities are influenced and restricted.

In addition, in the operations of removing the pallet from the pallet container unit and layering and stacking the pallet container unit, the robot technology is adopted to remove the pallet from the pallet container unit and to stack the pallet container unit again, and due to the structure of the product carton and the weight of the product, the robot cannot realize the operations of removing the pallet from the pallet container unit as a whole and layering and stacking the pallet container unit according to the product layers, and only one piece operation can be performed, which causes the unitization operation to be interrupted in the process, and as a result, the efficiency of the one piece operation is still very low and the operation cost is still very high.

Fig. 5 is a schematic structural diagram of a front lying layering unit 02, and the front lying layering unit 02 comprises a temporary storage and layering conveying line 4 and a follow-up plate leaning machine 5. The temporary storage and layering conveying line 4 is connected with one end of the goods stack turnover machine 2. The follower plate-leaning machine 5 is arranged on the temporary storage and layering conveying line 4 in a reciprocating manner.

Referring to fig. 5, 5.1 and also to fig. 1, the temporary storage and layering conveyor line 4 comprises a temporary storage and layering machine frame 40, a temporary storage and layering belt line 41, and a temporary storage and layering motion transmission device 42. The temporary storage and layering conveying line 4 has two functions, namely, the temporary storage and the temporary storage of the unit cargos to be layered lying forward are carried out, and the temporary storage and the layering conveying line are matched with the stacking head-on conveying line 212 to realize layering and stacking operation of the unit cargos lying forward.

Specifically, the temporary storage and layering conveyor line 4 is configured as a reciprocating bi-directional conveyor line, and the single-ended in-out conveyor end 400 is dynamically coupled to the outer end of the stack head-on conveyor line 212 in bi-directional conveying. An in-out support beam 401 is further arranged at the in-out conveying end 400 and is connected with the outer end of the stacking head-on conveying line 212, and when the stacking head-on conveying line 212 is turned to be in a horizontal position, the temporary storage and layering belt line 41 is connected with the outer end of the stacking head-on conveying line 212 in a conveying manner. The width dimension of the temporary storage and layering belt line 41 is related to the pallet size and the length dimension is related to the height dimension of the pallet unit load.

When the temporary storage and layering conveying line 4 outputs the unit cargos to be layered for layering and stacking operation, the bottom surface of the temporary storage and layering conveying line 4 temporarily stores the unit cargos to be layered and the top surface of the unit cargos to be stacked and heightened, which are lying forward on the stacking head-on conveying line 212, are close together. When the operation starts, the temporary storage and layering conveying line 4 and the goods stack head-on conveying line 212 carry out double-conveying-line combined conveying, namely, unit goods needing layering, which lie before, are jointly conveyed from the temporary storage and layering conveying line 4 to the goods stack head-on conveying line 212; when the unit cargo layer goods needing layering of the current lying passes through the joint of the double conveying lines, the temporary storage and conveying of the layering conveying line 4 are stopped immediately, and the conveying of the stack facing conveying line 212 is kept continuously, so that the layered and laminated unit cargo lying before is conveyed to the inner end of the stack facing conveying line 212; therefore, through the matched conveying of the double conveying lines, layering and stacking operation of the unit cargoes lying in front can be realized.

As shown in fig. 5 and 5.1, the follower backup machine 5 includes a follower backup 50, a backup frame 51, and a follower transmission device 52. Wherein, the follow-up backup plate 50 is arranged above the temporary storage and layering conveying line 4 in a vertical state. Specifically, the follower fence 50 is mounted in the fence frame 51 and connected to the follower transmission 52, and the vertical cargo blocking plane of the follower fence 50 is related to the top plane of the unit cargo. The follower rest 50 serves to follow up against the top surface of the unit load lying forward during operation, so that the unit load lying forward maintains a correct operating state during operation.
