Description

Technical Field

[0001] The invention relates to a package classification device and a classification method, belonging to the technical field of logistics management. Background Art

[0002] At present, e-commerce is developing rapidly, and online shopping has become a relatively large consumption channel for people. Correspondingly, in the field of logistics, the sorting volume of express parcels is also increasing. Many express delivery hubs are equipped with logistics sorting lines, but the current parcel sorting still relies on manual delivery of express parcels to the corresponding transmission lines based on subjective judgment, which consumes huge manpower and requires 24-hour uninterrupted personnel processing. At the same time, manual sorting of parcels is littered, and the safety and integrity of parcels are not paid attention to, which often results in losses caused by human factors such as loss and damage. At the same time, after the express is sorted, the standards are different, and the express loading is disorderly, which leads to the problem of extrusion and damage of parcels during transportation.

[0003] Therefore, there is a need for a parcel sorting device that can realize automatic sorting, limit package standards, provide a more standardized sorting process, reduce the use of personnel, reduce labor intensity, and facilitate loading to solve the above technical problems. Summary of the invention

[0004] Purpose of the invention: In view of the deficiencies in the prior art, the present invention provides a package sorting device and a sorting method to solve the problems mentioned in the above background technology.

[0005] Technical solution: A parcel sorting device, comprising a parcel conveyor belt and a parcel blocking structure arranged above the conveyor belt, wherein the parcel blocking structure is arranged to have at least three bottom surfaces, a first blocking structure, a second blocking structure and a third blocking structure, whose height from the conveyor belt decreases in sequence along the conveying direction of the conveyor belt; The package blocking structures are all movably mounted on the baffle plate at the side of the conveyor belt, and the first blocking structure, the second blocking structure and the third blocking structure are mounted on the baffle plate at equal intervals; The first blocking structure, the second blocking structure and the third blocking structure are hinged with the baffle, and a self-resetting travel switch that allows rotation in the conveying direction of the conveyor belt is arranged at the hinge, and the self-resetting travel switch signal is connected to the whole machine controller; The conveyor belt is arranged at an angle, and a smooth sliding plate parallel to the baffle is arranged on the side of the conveyor belt away from the baffle. Separation channels are opened at the positions corresponding to the positions of the sliding plate and the first blocking structure, the second blocking structure and the third blocking structure. The separation channel is controlled to be on and off by a self-resetting travel switch.

[0006] The present invention uses an inclined conveyor belt structure and different blocking structures according to the size of the packages. The blocking structures are triggered to open separation channels, allowing the packages to enter designated partitions, thereby achieving classification of package sizes and making transportation more convenient. At the same time, problems such as package loss caused by the concentration of various types of packages and inconvenient management of small packages can be avoided.

[0007] The separation channel includes a separation door hinged to the outer side of the slide plate and a locking device arranged near the other end of the separation door; A self-resetting component is provided at the hinge between the separation door and the slide plate; The locking device comprises an electromagnetic attractor arranged on the slide plate, a self-resetting locking pin corresponding to the position of the electromagnetic attractor is arranged on the separation door, a pin hole is arranged at a position corresponding to the position of the electromagnetic attractor and the self-resetting locking pin, and the self-resetting locking pin and the pin hole are matched and connected in a locked state; The self-resetting locking pin includes a pin sleeve, a pin shaft slidably arranged in the pin sleeve, and a reset spring arranged in the pin sleeve and sleeved on the outside of the pin shaft. The pin sleeve is fixedly installed at the outer side of the separation door corresponding to the position of the electromagnetic attractor.

[0008] The separation door is positioned by setting an electromagnetic attractor independent of the self-resetting stroke switch. When not in action, the separation door can be locked to keep the slide plate smooth and flat to avoid the package from getting stuck.

[0009] The ratio of the distance height between the first blocking structure, the second blocking structure and the third blocking structure and the conveyor belt surface is 5:3:1, and the distance height between the third blocking structure and the conveyor belt surface ranges from 10 cm to 15 cm.

[0010] It also includes a weighing platform arranged at the starting end of the conveyor belt and connected to the whole machine controller signal, the weighing platform and the starting end of the conveyor belt are located in the same plane, and the starting end of the conveyor belt is transitioned to an inclined state through a bending section; A pushing mechanism is provided on the side of the weighing platform away from the conveyor belt, and the pushing mechanism includes a push plate located at the same horizontal plane as the upper end surface of the weighing platform, and the push plate realizes reciprocating motion through a first crank rocker mechanism; The slide plate is provided with a heavy object separation channel near the starting end of the inclined part of the conveyor belt, and is provided with a separation door and a locking device with the same structure as the separation channel. The electromagnetic attractor on the heavy object separation channel is controlled to be on and off by the signal of the weighing platform.

[0011] In order to separate heavier packages and avoid small but heavy packages from crushing other packages during transportation, heavier packages are separated and given priority during loading, which can better ensure the integrity of other packages, lower the center of gravity of the vehicle, and make the transportation process more stable.

[0012] The self-resetting assembly includes a servo motor, a second crank-rocker mechanism driven by the servo motor, a rack connected to the second crank-rocker mechanism, and a sector gear ring with one side welded to the separation door as one body; The servo motor is mounted on a partition, a guide groove for the rack to slide is provided on the partition, the rack is slidably arranged in the guide groove, the second crank rocker mechanism is hinged to one end of the rack, and the rack is meshed with a sector gear ring.

[0013] In order to prevent lighter packages from being larger in size and unable to open the separation door by their own weight, when the self-resetting travel switch is triggered, the servo motor is controlled to rotate at the same time, which can actively open the separation door to separate the packages.

[0014] A classification method implemented by using a package classification device comprises the following steps: Step 1: Set the parcel weight threshold, separate the heavier parcels first, and set the total weight of a single shipment to include 2T, 5T and 10T; Step 2: Place the packages one by one on the weighing platform, measure the weight of the packages, and adjust the reciprocating motion time of the push mechanism to 2S; Step 3: According to the weight and size of the parcels, parcel partitions are set at the end of each separation channel, including heavy parcel area, large parcel area, medium-sized parcel area, small and medium-sized parcel area, and small parcel area; Step 4: Associating the weighing platform with the electromagnetic attractor on the heavy object separation channel, and associating the self-resetting travel switch on each blocking structure with the electromagnetic attractor at its corresponding position one by one to achieve separate control; Step 5: When the package is running on the conveyor belt, when the height of the package is not enough to pass through the current blocking structure, it collides with the blocking structure, and the blocking structure swings to trigger the self-resetting travel switch. The self-resetting travel switch signal is transmitted to the whole machine controller, and the whole machine controller sends an electrical signal to the corresponding electromagnetic attractor, and the electromagnetic attractor is disconnected. The package slides to the separation channel by gravity and enters the designated partition; Step 6: After the parcel is placed on the weighing platform and weighed, the whole machine controller accumulates the weight. When the weight reaches the set value, the pushing mechanism stops moving. That is, the parcels that a logistics vehicle needs to transport are classified and loaded in order from heavy to light and from large to small according to the weight and size of the goods.

[0015] Beneficial effects: The present invention adopts an inclined conveyor belt structure, and then sets different blocking structures according to the size of the package. The blocking structure is triggered to open the separation channel, so that the package enters the designated partition, and the package size is classified, which is more convenient for transportation. At the same time, it avoids the problem of package loss caused by the concentration of various types of packages, and the inconvenient management of small packages. BRIEF DESCRIPTION OF THE DRAWINGS
