In the related art, package sorting is performed by manual sorting or by using automatic sorting equipment. The manual sorting speed is low, and the accuracy is low; when using automatic sorting equipment to sort, the sorting accuracy is also limited by the automation level and accuracy of the automatic sorting equipment.

To overcome this problem, embodiments of the present disclosure provide a method, an apparatus, a system, a computer-readable storage medium, and an electronic device for sorting packages.

Fig. 1 schematically illustrates a method of parcel sorting according to an exemplary embodiment of the present disclosure. The method provided by the embodiment of the present disclosure can be executed by any electronic device with computer processing capability, such as a terminal device and/or a server. The embodiment of the disclosure provides a parcel sorting method, which is applied to a transmission belt, wherein a plurality of swing arms and a plurality of parcel grids are arranged on the transmission belt, and the swing arms correspond to the parcel grids one by one. Referring to fig. 1, a method for sorting packages provided by the embodiments of the present disclosure may include the following steps:

step S102, when the first parcel is at the start position, a first numerical value of the counter is obtained.

Step S104, acquiring a counter difference value of a first wrapping grid corresponding to the first wrapping according to the wrapping information of the first wrapping, wherein the counter difference value is a counting difference value of a counter in the process that the articles on the conveyor belt are transmitted to the wrapping grid position corresponding to the counter difference value from the initial position.

And step S106, acquiring a target value of the counter when the first parcel reaches the first parcel slot according to the first value and the difference value of the counter.

And step S108, when the numerical value of the counter is the target numerical value, generating a swing arm signal to drive a swing arm to act, and pushing the first wrapping into the first wrapping lattice opening.

In the embodiment of the disclosure, by setting a difference value of a counter from a starting position to each parcel lattice, and determining a value of a counter when a first parcel arrives at the starting position, the counter when the first parcel arrives at the first parcel lattice according to the difference value of the counter of the first parcel corresponding to the first parcel, and when a timer counts and reaches the value of the counter, determining that the first parcel arrives at the first parcel lattice, a pushing position of the first parcel is determined quickly and accurately, so that the swing arm is used for pushing the first parcel to the first parcel lattice.

As shown in fig. 2, in the embodiment of the present disclosure, a first wrapping cell 231, a second wrapping cell 232, a third wrapping cell 233, and a fourth wrapping cell 234 are disposed on the conveyor belt 210, and the four wrapping cells correspond to the first swing arm 241, the second swing arm 242, the third swing arm 243, and the fourth swing arm 244 one by one, and in addition, other wrapping cells and swing arms not shown in the drawings may be disposed on the conveyor belt. The amount of change in the counter value of the article moving from the home position 220 to a parcel compartment as the article is conveyed by the conveyor is defined as the counter difference for that parcel compartment.

Before step S102, package information of the first package obtained by scanning the code by the start position code scanning device needs to be obtained, and it is determined that the first package is at the start position according to the package information of the first package.

Before step S104, it is necessary to obtain the counter difference of each parcel bay according to the set conveying speed of the conveyor belt and the distance between each parcel bay and the start position, and store the corresponding relationship between the counter difference of each parcel bay and the parcel bay.

As shown in fig. 2, distances between the first wrapping bay and the second wrapping bay, and between the third wrapping bay and the fourth wrapping bay and the initial position are L1 m, L2 m, L3 m and L4 m, respectively. When the conveyor belt runs at a constant conveying speed v m/S and the number of counting pulses of the counter per second is S, the difference values of the counters corresponding to the first parcel grid, the second parcel grid, the third parcel grid and the fourth parcel grid are L1/vS, L2/vS, L3/vS and L4/vS respectively. After the parcel shelf and the corresponding counter difference value are stored in a one-to-one correspondence manner, the parcel shelf corresponding to the parcel and the counter difference value corresponding to the parcel shelf can be inquired according to the parcel information.

Thus, when the parcel starts to move from the initial position, the initial value of the numerical value of the counter is recorded, when the numerical value variation of the counter is the counter difference value of the parcel lattice corresponding to the parcel, the parcel is considered to reach the parcel lattice corresponding to the parcel, the swing arm corresponding to the parcel lattice is controlled to act at the moment, and the parcel can be pushed into the corresponding parcel lattice.

Specifically, after acquiring the package information according to the first package, a destination group corresponding to the first package is acquired, and a first package bin corresponding to the first package is determined according to the destination group.

The method provided by the embodiment of the present disclosure may be executed by a PLC controller, but is not limited to this in practical application. And the PLC carries out array storage of the structure data on the package lattice corresponding to the received package to form a storage list. The size of the storage list can be defined as N, that is, a single conveyor belt can simultaneously track N packages, where N is a positive integer, and a value can be taken according to actual needs, for example, N is set to be greater than or equal to 40 and less than or equal to 60. The speed of the conveying belt, namely the belt conveying body, is calibrated, the distance between each packaging grid opening and the initial position and the number of coded disc counting pulses of the conveying belt form a one-to-one correspondence relationship, and the coded disc counting pulses corresponding to each packaging grid opening are stored into a PLC (programmable logic controller) as static variables for query.

In the embodiment of the disclosure, the conveyor belt is further provided with an abnormal parcel shelf, and if the parcel barcode of the second parcel cannot be identified or the second parcel does not have a corresponding target parcel shelf, the second parcel is conveyed to the abnormal parcel shelf.

Here, the package without the corresponding package bin is an abnormal package, and may be a through package or a wrong-line package, for example. Specifically, after the parcel is scanned, whether the parcel is an abnormal parcel or not can be judged according to parcel information obtained by scanning the code.

As shown in fig. 3, in the method for sorting packages according to the embodiment of the present disclosure, steps S301 to S303 are performed in a loop from the array with the storage list serial number of 1 until the storage list serial number is 50.

Step S301, judging whether sorting is needed or not and whether the current code disc pulse number is equal to the target code disc pulse number or not, and if yes, executing step S302. Here, a sorting identifier may be set, and whether the package corresponding to the current array needs to be sorted is determined according to the sorting identifier.

When the sorting identification represents that the package needs to be sorted, the package is a normal package and has a corresponding target package lattice. When the sorting identifier indicates that the package does not need to be sorted, the package is an abnormal package and does not have a corresponding target package grid.

When the packages are scanned, the sorting identifications of the packages can be determined to be sorted and not to be sorted according to the package information obtained by scanning the codes. When the packages needing to be sorted meet the set conditions in the step S301, the step S302 and the subsequent steps are continuously executed, and the packages not needing to be sorted are not allocated with the corresponding package slots, and finally enter the set abnormal package slots.

In step S302, an operation flag is set to 1.

Step S303, add 1 to the storage list number.

After step S302, steps S304 to S306 need to be executed.

In step S304, the drive flag is set to 1.

Step S305, the swing arm motor is driven to act.

Step S306, setting the action identifier to be 0, and releasing the array resource of the current array to circularly utilize the list resource.

In the running process of the belt conveying body, the PLC compares the number of a package lattice corresponding to the current package in the storage list, inquires the code disc counting pulse of the corresponding package lattice, namely the difference value of a counter, and calculates the target code disc pulse number of the package lattice corresponding to the current package, namely the target value by combining the code disc pulse number of the conveying belt when the current package is positioned at the initial position.

In the embodiment of the present disclosure, when the value of the counter reaches the preset first threshold, the counter may be cleared. Specifically, the PLC maintains the storage list, and after the swing arm moves, the array items corresponding to the parcel shelf corresponding to the swing arm are emptied, so that resource space recycling is realized. The first threshold value M of the code wheel counter can be defined to be 6-8 ten thousands, and when the number reaches the first threshold value, the code wheel counter is automatically cleared.

In the embodiment of the disclosure, the PLC controller only tracks the package assigned with the package slot, and whether the package enters the package slot is only related to the difference value of the counter of the package slot bound by the package. The unidentified packages are conveyed to the set abnormal package cell, and the package arriving at the abnormal package cell can be processed by manual sorting or other processing modes. Therefore, according to the technical scheme of the embodiment of the disclosure, when the unidentified packages appear, the normal sorting of the packages is not influenced, manual intervention on the conveyor belt is not needed, and the coupling degree is low.

The package sorting process of the embodiment of the disclosure relates to four-level physical connection and signal transmission of a switch, a PLC (programmable logic controller), an ASI (Actuator-Sensor-Interface) module and a swing arm motor driver. The ASI module is used for bidirectional information exchange between a controller (master station) and a sensor/actuator (slave station).

The PLC controller can directly generate a swing arm signal and output the swing arm signal to the swing arm motor without passing through an external controller and a gateway, and the control architecture is simple.

The swing arm sorting technical scheme in the embodiment of the disclosure adopts the frequency converter and the variable frequency motor to drive the swing arm to move, has high force ratio, and can quickly and efficiently move to sort large packages containing dozens of packages to dozens of packages.

In the implementation of the invention, a Siemens PLC can be used as a main controller, and the communication with a DWS (Data Warehouse Service) system is realized in real time through an Ethernet local area network. According to the communication protocol agreed by both parties, the PLC sends heartbeats to the DWS system at regular time, and long connection is maintained. The DWS system automatically scans the packages in five planes quickly, and obtains corresponding package grids according to the package information obtained by scanning the codes. The DWS sends the package and the package grid information to the PLC controller, so that the PLC controller controls the package to fall into the designated package grid.

The DWS system can scan the code of the package at the self-defined initial position and record the code scanning time as the time for the package to reach the initial position, and can scan the code of the package before entering the initial position and determine the time for the package to reach the initial position when the package reaches the initial position.

And under the condition that the DWS cannot acquire the bar code information of the package correctly, an artificial bar code gun can be selected for code complementing. Under the condition that the parcel bar code is damaged, a parcel shelf can be manually specified through a shelf button.

In the embodiment of the disclosure, the conveying speed of the conveyor belt can reach 80 m/s, the sorting amount of packages can be about 3500 pieces per hour, and the sorting accuracy rate reaches 98%.

After the swing arm signal is generated, the PLC controller can be communicated with the ASI module through a Profinet network to control a swing arm motor driver to drive a swing arm motor to act, and the function that the swing arm mechanism swings goods to enter a wrapping lattice opening is achieved.

A swing arm proximity switch is arranged at a set position near the swing arm, and when the swing arm proximity switch senses that the swing arm is close to the swing arm, a swing arm proximity signal is generated and transmitted to the PLC server through the ASI module. Here, the swing arm is close to the set position, which indicates that the swing arm has swung in place and the parcel has entered the corresponding parcel shelf. And after receiving the swing arm approaching signal, the PLC server generates a swing arm stopping signal and controls the swing arm motor to stop.

The method for sorting the parcels in the embodiment of the disclosure sets the difference value of the counter from the initial position to the parcel shelf, and starts counting when the articles reach the initial position, so that whether the articles reach the target parcel shelf can be judged according to the counting data and the difference value of the counter of the target parcel shelf, and the parcels can be sorted quickly and accurately.
