Description

Multi-channel parallel express sorting method based on spiral slide

technical field

The invention relates to the technical field of express sorting, in particular to a multi-channel parallel express sorting method based on a spiral slide.

Background technique

In today's information age, especially in the current Internet + economic model, logistics is a very important link. Today's consumers, especially the younger generation, are more inclined to shop online, so the daily circulation of domestic and foreign express delivery is huge. In the process of express transportation, sorting the express is essential, and this process determines whether the express can be transported to the correct direction. At present, express sorting equipment has been widely used in express companies, reducing the workload of express sorting personnel to a certain extent.

The invention patent with the application number of 201810101142.5 discloses a multi-level stacking combined package sorting-packing-conveying device, which is used for the sorting, packing and conveying of packages, and can realize the classification and bagging of the packages after scanning codes according to their addresses. , The whole bag is packed and the whole bag is transported to the conveyor belt. Its shortcomings are: 1. After the bags are filled, they all need to be taken out through the wrapping device. The wrapping device is a lifting platform with a manipulator, and it can only take out one collection bag full of packages at a time. If there are multiple collection bags full of packages at the same time, the lift table has to be taken out one by one. During the process of waiting for the lift table to be taken out, the entire sorting device needs to temporarily stop sorting, which reduces the sorting efficiency. 2. After the collection bag in the collection box is full, it needs to be closed first, then taken out through the unpacker, and finally a new collection bag is automatically opened. In the process of "bag", the entire sorting device needs to temporarily stop sorting, which reduces the sorting efficiency.

The invention patent with the application number of 201610417812.5 discloses a three-dimensional turret express sorting system, which can distinguish express packages according to their destinations and transport them to corresponding storage containers according to different destinations. Its shortcomings are: 1. The turret sorting device has multiple layers (at least two layers), multiple transfer stations, and realizes "one inlet and multiple outlets", which is a pyramid structure of "small upper and lower lower". . When there are many terminal areas for express sorting, 3 or even 4 layers may be required, which will result in a very large area at the lower end, and each package enters the turret sorting device from the top layer, and passes through the turret sorting device. Only by layer-by-layer sorting can it enter the lowermost parcel collection box. The parcel sorting path is long and the energy consumption of the equipment is relatively large. 2. Only one package is allowed to enter the top layer of the turret sorting device at a time. When the number of packages is large, the efficiency of the equipment is slightly lower.

The sorting steps are as follows:

S01, divide the subsystem:

The user divides one or more subsystems in the sorting system for sorting according to the number of terminal areas and the number of packages to be sorted. The subsystems include one or more sorting towers connected up and down; the divided subsystem groups The sorting needs of all terminal areas should be met;

In this step, the sorting tower includes multiple bagging output devices, and each bagging output device is only used to collect packages in one end area;

S02, the package enters the corresponding bagging output device through the sorting path:

a. The packages that have been scanned externally are transported to the transfer area of the uppermost sorting tower in the subsystem;

b. The controller firstly controls the stepping motor A to start according to the pre-calculated package sorting path, so that the sweeping disc rotates and sweeps the package to the corresponding package drop port; and then controls the hydraulic cylinder A to start to make the package drop port The movable plate at the position rotates downward to open the package drop opening, and the package falls into the corresponding bagging output device or enters the package drop channel;

c. The package entering the package drop channel falls to the transfer area of the adjacent lower sorting tower, and then repeats the step b process, so that the package finally falls into the corresponding bagging output device;

S03, package and bag output:

a. After the packages in the same end area fall into the collection bag of the bagging and output device, they are pressed on the bag discharging board through the collection bag;

b. When the photoelectric sensor detects that the package in the collection bag exceeds the preset height, or the pressure sensor detects that the package in the collection bag exceeds the preset weight, the controller immediately controls the hydraulic cylinder B to start, so that the bag discharge plate goes down Rotate to open the lower opening of the bagging output device and the inlet opening of the collecting bag of the tower shell;

The collection bag discharged from the lower opening of the bagging output device enters the bowl-shaped inner cavity of the tower shell through the collection bag inlet of the tower shell, slides down the cavity wall of the bowl-shaped cavity, and collects from the tower shell. The bag is discharged from the discharge port, and then enters the collection bag drop port of the carrier plate through the deflector slide, falls on the spiral slide, slides down the spiral slide, and finally discharges from the general outlet of the collection bag at the lower end of the spiral slide.

A further technical solution of the present invention is: before express sorting, the sorting system is in an initial state, and in this state:

b, the movable plate is in the position to close the drop port of the package;

c. The bag discharge plate is at the position of closing the lower opening and the inlet of the collection bag.

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

1. High efficiency of multi-channel synchronous sorting: multiple sorting towers are installed on each carrier board of the main frame, and each sorting tower is connected to the corresponding lower sorting tower through the parcel drop channel. As a result, multiple sorting subsystems that operate independently and do not interfere with each other can be divided according to needs, and each sorting subsystem contains all the bagging and output devices classified in the end area. Multiple sorting subsystems can perform sorting at the same time, which is equivalent to multi-channel sorting. Compared with the single-channel sorting of the existing express sorting system, the present invention improves the sorting efficiency.

2. Path optimization and high sorting efficiency: multiple carrying boards can be set up along the spiral slide from top to bottom, each carrying board is equipped with a sorting tower, and the sorting tower is equipped with a bagging output device for a certain end area , that is, the sorting path of the package can be long or short, and it can be directly collected in the bagging output device of the upper sorting tower, or collected in the bagging output device of the lower sorting tower. Compared with the existing express sorting system with pyramid structure, all the packages have to go through the longest sorting path into the lowermost package collecting box. The sorting path of the present invention is better and energy consumption is saved.

3. Sustainable sorting and high sorting efficiency: when the bag pick-up frame is in the position of picking up the collection bag, the splice enclosure and the connecting cloth enclosure connected to one side of the splice frame and located at the lower end of the splice enclosure form an enclosure. The space for temporarily receiving the package can play the role of temporarily receiving the package; when the bag-holding frame that has picked up the collection bag moves from the position of picking up the collection bag to the position of receiving the package, the connecting cloth is put into the reel, so that the upper opening is opened. And the bag inlet port is opened, and the temporarily received package in the receiving enclosure will fall into the collection bag, thus ensuring the continuous express sorting, and it is not necessary to suspend the entire sorting process because the bag frame is in the position of picking up the collection bag. .

4. There is no need to wait for discharge. High output efficiency: all the collection bags discharged from the sorting tower are confluent to the spiral slide, and finally discharged from the lower end of the spiral slide. The process of discharging the collection bags does not use any electrical or mechanical assistance, and consumes zero energy. And each sorting tower does not need to coordinate the discharge relationship with other sorting towers, as long as the output requirements are met, the collection bag will be discharged.

The present invention will be further described below with reference to figures and embodiments.

When the photoelectric sensor 4123 detects that the package in the collection bag 43 exceeds the preset height, or the pressure sensor detects that the package in the collection bag 43 exceeds the preset weight, the controller immediately controls the hydraulic cylinder B491 to start, so that the bag is discharged The plate 44 is rotated downward, thereby opening the lower opening 4111 of the bagging output device 4 and the collecting bag inlet 22 of the tower casing 2;

c. The controller then controls the electromagnet A452 and the electromagnet B454 to be powered off, so that the connecting piece 4311 and the suction ring piece 4331 of the collection bag 43 are disconnected from the electromagnet A452 and the electromagnet B454 respectively, so that the collection bag 43 only passes through the hook ring piece. 4332 is hung on the hook finger 455 of the bag holding frame 45, then the package in the collection bag 43 pulls out the drawstring 432 from the outlet end of the drawstring installation cavity by its own weight, and the collection bag 43 is closed;

d, the controller then controls the turning motor 453 to start, turning the hook finger 455 to a vertical downward state, and the closed collection bag 43 drops immediately and is discharged from the lower opening 4111 of the bagging output device 4 .

S04, the collection bag is discharged through the spiral slide:

The collection bag 43 discharged from the lower opening 4111 of the bagging output device 4 enters the bowl-shaped inner cavity of the tower shell 2 through the collection bag inlet 22 of the tower shell 2, and slides down along the cavity wall of the bowl-shaped inner cavity. It is discharged from the collection bag discharge port of the tower shell 2, and then enters the collection bag drop port 121 of the carrier plate 12 through the deflector plate 13, falls on the spiral slide 11, slides down along the spiral slide 11, and finally exits the spiral slide 11. The collection bag general outlet 111 is discharged.

The working process of the bagging output device in the express sorting system that can be multi-channel synchronous sorting is as follows:

Before the package is automatically bagged and output, the bagging output device is in the initial state, in this state:

a, the hook finger 455 is in a vertically downward state;

b, the bag holding frame 45 picks up a collection bag 43 and is in the position of receiving the package;

c. The bag discharging plate 44 is rotated to a horizontal position, thereby closing the lower opening 4111 of the bagging output device 4 and the collecting bag inlet 22 of the tower casing 2 .

S01, the collection bag receives the package:

The sorted packages fall into the collection bag 43 through the upper opening 4122 of the upper plate 412 . After the package falls into the collection bag 43 , it is pressed on the bag discharge board 44 through the collection bag 43 .

S02, collection bag closing output:

a. When the photoelectric sensor 4123 detects that the package in the collection bag 43 exceeds the preset height, or the pressure sensor detects that the package in the collection bag 43 exceeds the preset weight, the controller immediately controls the hydraulic cylinder B491 to start, so that the bag is discharged The plate 44 is rotated downward, thereby opening the lower opening 4111 of the bagging output device 4 and the collecting bag inlet 22 of the tower casing 2;

b. The controller then controls the electromagnet A452 and the electromagnet B454 to be powered off, so that the connecting piece 4311 and the suction ring piece 4331 of the collection bag 43 are disconnected from the electromagnet A452 and the electromagnet B454 respectively, so that the collection bag 43 only passes through the hook ring piece. 4332 is hung on the hook finger 455 of the bag holding frame 45, then the package in the collection bag 43 pulls out the drawstring 432 from the outlet end of the drawstring installation cavity by its own weight, and the collection bag 43 is closed;

c, then the controller controls the turning motor 453 to start, turning the hook finger 455 to the vertical downward state, and the closed collection bag 43 drops immediately and is discharged from the lower opening 4111 of the bagging output device 4 .

S03, pick up a new collection bag:

When the closed collection bag 43 is discharged, the controller immediately performs the following two controls at the same time:

a, control the stepping motor B461 to start, so that the bag holding frame 45 is moved to the position of picking up the collecting bag;

b. Control the hydraulic cylinder B491 to start, so that the bag discharge plate 44 is rotated upward to a horizontal position, thereby closing the lower opening 4111 of the bagging output device 4 and the collecting bag inlet 22 of the tower shell 2;

When the bag-holding frame 45 is moved to the position of picking up the collection bag, the electromagnet B454 and the electromagnet A452 at the lower end of the bag-holding frame 45 are activated to adsorb a collection bag 43 on the uppermost layer of the bag storage frame to the lower end of the bag-holding frame 45;

After the collection bag 43 is adsorbed to the lower end of the bag holding frame 45, the controller performs the following two controls simultaneously:

a, control the turning motor 453 to start, and turn the hook finger 455 to the vertical upward state;

b. Control the stepping motor B461 to start, so that the bag holding frame 45 moves to the position of receiving the package.

In step S03, the elastic force of the push spring 424 makes the collection bags 43 stacked and installed on the bag storage rack close to each other, and the uppermost collection bag 43 always abuts against the lower end of the elastic pressing button 4221 on the upright column 422, thereby ensuring the safety The distance between the holding bag frame 45 at the position of picking up the collecting bag and the uppermost collecting bag 43 is always kept constant, and the distance will not gradually increase due to the consumption of the collecting bag 43, thus eliminating the influence of the distance change on the adsorption force.

In step S03, when the bag holding frame 45 picks up the collection bag, the adsorption force received by the uppermost collection bag 43 is greater than the adsorption force received by the lower collection bag 43, and the adsorption force provided by the electromagnets A452 and B454 of the bag holding frame 45 Only the uppermost collection bag 43 can be adsorbed to the lower end of the pocket frame 45 through the snap button 4221 on the upright column 422 , but it is not enough for the lower layer collection bag 43 to pass through the snap button 4221 on the upright column 422 .

In step S03, when the bag-holding frame 45 receives the collection bag 43, the splice enclosure 47 and the connecting cloth 463 connected to one side of the bag-holding frame 45 and located at the lower end of the splice enclosure 47 are encircled to form a temporary package receiving enclosure. The space is used to temporarily receive the package; when the bag-holding frame 45 that has picked up the collection bag 43 moves from the position of picking up the collection bag to the position of receiving the package, the connecting cloth 463 is collected into the cloth roll 462, so that the upper opening 4122 When the package inlet port 451 is opened, the temporarily received package in the receiving enclosure 47 will fall into the collection bag 43, thereby ensuring that the express sorting continues.
