Description

Technical Field

[0001] The present invention relates to the technical field of logistics, and in particular to an automated express loading and unloading sorting operation system. Background Art

[0002] At present, the fully automated sorting system in the express transit market is already very mature, but the technology only stays at the stage of mechanically sorting different express parcels to designated locations. After the express parcels are sorted, they need to be loaded manually; when unloading, they also need to be moved manually from the vehicle to the telescopic belt conveyor for transmission and sorting. Both unloading and loading require a lot of manpower. In this way, the company's operating costs will increase, and the cost of receiving and sending express parcels for consumers will also increase. At the same time, manual sorting increases the time cost, and the time it takes for consumers to receive the goods is extended, which reduces the consumer's experience. Because the goods are moved up and down manually, it is very easy to cause collision and damage to the goods. Furthermore, since the height of the vehicle is about 2 meters, the height of the goods is also so high, resulting in a lot of extrusion and damage to the objects.

[0003] In order to solve these problems, the present invention provides a fully automatic unmanned operating system from unloading to sorting and loading, and is equipped with a truck with a multi-layer structure, which can effectively save labor costs and shorten time, and can effectively solve the problem of damage caused by squeezing of express parcels. At the same time, it can also reduce the company's operating costs and the cost of consumers' collection and delivery, and increase consumers' experience. Summary of the invention

[0004] The purpose of the present invention is to provide an automated express delivery sorting and operation system to solve the above-mentioned defects caused by the prior art.

[0005] An automated express delivery sorting and operation system includes an unloading system, a transmission system 1, a sorting system, a transmission system 2 and a loading system.

[0006] The unloading system comprises multiple lifting unloading transition layers, and a plurality of universal wheels are closely arranged above each unloading transition layer, and each universal wheel is driven by a separate motor, and the motor is controlled by a computer;

[0007] The transmission system includes a unloading conveyor belt, a depalletizing robot arm, a single piece separator, a centering machine and a delivery platform. The depalletizing robot arm is arranged at the front end of the unloading conveyor belt; the top of the single piece separator is equipped with a sensor 2 and is controlled by a computer and the lower end is equipped with a module transmission device;

[0008] The sorting system includes a circular guide rail, a sorting trolley and a code scanning sorting machine. The sorting trolleys are provided with a plurality of trolleys and move on the circular guide rail. All the sorting trolleys are linked together and driven by a motor. The code scanning sorting machine is arranged above the circular guide rail. A sensor three is arranged on the top of the code scanning sorting machine, and the sensor three is controlled by a computer.

[0009] The second transmission system includes a oscillating wheel sorter, a transition conveyor belt, a DWS system and a loading conveyor belt. The transition conveyor belt and the loading conveyor belt are respectively arranged at two ends of the oscillating wheel sorter, and the DWS system is arranged at the rear end of the transition conveyor belt.

[0010] The loading system comprises multiple lifting loading transition layers and stacking mechanical arms, and a plurality of universal wheels 2 are closely arranged above each loading transition layer, and each universal wheel 2 is driven by a separate motor, and the motor is controlled by a computer.

[0011] Preferably, telescopic rods 1 are evenly distributed around the unloading transition layer, and all telescopic rods 1 are vertically arranged upward and their top ends are connected to the edge of the unloading transition layer.

[0012] Preferably, telescopic rods 2 are evenly distributed around the loading transition layer, and all telescopic rods 2 are vertically arranged upward and their top ends are connected to the edge of the loading transition layer.

[0013] Preferably, the end of the depalletizing robot arm is equipped with a vacuum suction cup 1 and a sensor 1, and the sensor 1 is controlled by a computer; the end of the palletizing robot arm is equipped with a vacuum suction cup 2 and a sensor 4, and the sensor 4 has a volume recognition function and a code scanning function and is controlled by a computer.

[0014] Preferably, the automatic loading and unloading express mail sorting operation system comprises the following operation steps:

[0015] S1: Each unloading transition layer is adjusted to be flush with the height of each compartment in the multi-layer truck, and then the express items on the compartment in the truck are transferred to the corresponding unloading transition layer by the conveyor belt on the compartment;

[0016] S2: Each unloading transition layer is adjusted to a height flush with each unloading conveyor belt. The depalletizing robot arm depalletizes the stacked express items at the rear end of the unloading transition layer and places them in the empty space of the unloading conveyor belt. When the goods at the rear end of the unloading transition layer are unloaded by the depalletizing robot arm, the goods at the front end of the unloading transition layer are moved to the front end through the universal wheel 1 according to the information collected by the sensor 1 of the depalletizing robot arm, so that they are orderly transferred to the unloading conveyor belt.

[0017] S3: The single-piece separator separates the closely packed express parcels and transfers each express parcel backwards individually. The centering machine then transfers each express parcel to the delivery platform in the center. The delivery platform then transfers each express parcel to each sorting cart individually.

[0018] S4: When the sorting trolley carrying the express is transported along the circular guide rail to the bottom of the code scanning sorting machine, the express delivery bill information on the express is automatically scanned by the sensor 3 on the code scanning sorting machine, and then the sorting trolley carrying the express is further transported along the circular guide rail to the corresponding grid according to the acquired information, and then the express on the sorting trolley is transferred to the front end of the loading conveyor belt under the grid;

[0019] S5: When the express items on the loading conveyor belt are transferred to the bottom of the DWS system, the DWS system measures the volume of the express items and scans the weight information on the waybill. Then, each express item is classified according to the collected information, and the classified express items are transferred to the corresponding loading transition layer through the swing wheel sorter;

[0020] S6: The express parcels on each loading transition layer are arranged in order by the universal wheel 2 on the layer, and the arranged express parcels are palletized by the vacuum suction cup 2 based on the information collected by the sensor 4 of the palletizing robot arm, while following the palletizing principle of "big ones do not press small ones, heavy ones do not press light ones";

[0021] S7: When the express parcels are stacked to the set height, the stacking robot arm is moved outward, and then each loading transition layer is adjusted to the height flush with each compartment in the multi-layer truck. Finally, the stacked express parcels are transferred as a whole to the truck compartment through the universal wheel 2 on each loading transition layer.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] The present invention realizes unmanned operation from unloading to loading, reducing labor costs. It also avoids the problem of express damage caused by manual unloading and loading, and the problem of damage caused by squeezing of express because traditional trucks need to stack express at a height of about two meters.
