Quick and accurate sorting and delivery of these commodities to designated locations (such as designated shelves, processing areas, shipping platforms, etc.) require fast logistics sorting devices and systems. At the same time, when the supplier or the cargo owner notifies the logistics center to deliver the goods according to the distribution instructions, the sorting system also needs to accurately find the location of the goods to be shipped from the huge high-level inventory storage system in the shortest time The required quantity is out of the warehouse, and the different quantities of goods taken out from different storage positions are transported to different tally areas or distribution stations according to the distribution location for loading and distribution.

The existing domestic and foreign logistics sorting equipment mainly adopts the combination of material conveyor belt and multi-degree-of-freedom manipulator, which needs to assist a large number of sensor devices to realize the positioning of the transmission process. At the same time, once the working space environment changes, it needs to be equipped with additional auxiliary transmission equipment. Sorting of goods or commodities.

Detailed ways

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

Referring to Fig. 1-2, this embodiment provides a logistics sorting device, including a conveying plate 1 and a supporting plate 2, the bottom of the conveying plate 1 is provided with a number of conveying plate roller teeth 11, and the conveying plate roller teeth 11 are square platforms Shaped and neatly arranged side by side, the support plate 2 is provided with an X-axis drive block and a Y-axis drive block. The driving roller teeth 31, the driving roller teeth 31 have the same structure as the conveyor plate roller teeth 11, and the distance between two adjacent roller teeth can at least accommodate a single roller tooth. When driving the conveyor plate 1, the X-axis drive block and the Y-axis drive block One of the driving roller teeth 31 is meshed with the roller teeth 11 of the conveying plate, and drives the conveying plate 1 to move along the X-axis or the Y-axis with the distance of a single roller tooth as the unit.

In this embodiment, as shown in Figure 3, the transmission assembly 4 includes a positioning guide rail 41 and a screw mandrel 42, the positioning guide rail 41 is fixed on the support plate 2, the screw mandrel 42 is arranged along the positioning guide rail 41, and the driving device adopts two servo motors 5. Two servo motors 5 are installed at both ends of the positioning guide rail 41, respectively connected to the two ends of the screw rod 42 through a coupling, and synchronously rotate in the same direction to drive the screw rod 42 to rotate, and the driving block 3 is sleeved on the screw rod 42 Above, the corresponding screw rod 42 on the driving block 3 is provided with an internal thread, and the driving block 3 is arranged in smooth contact with the positioning guide rail 41 , so that the driving block 3 is driven by the rotating screw rod 42 and can translate along the positioning guide rail 41 .

There are two X-axis drive blocks and two Y-axis drive blocks respectively, which are arranged in parallel and spaced apart and distributed around the support plate 2 . Since the driving roller teeth 31 are in the shape of a quadrangular truss, and the conveying plate roller teeth 11 are in the shape of an inverted quadrangular truss, when the driving roller teeth of the X-axis driving block drive the conveying plate 1 to move, the conveying plate roller teeth 11 can move from the Y-axis driving block. The drive roller passes through the tooth gap, so it has no effect on the Y-axis drive block; vice versa.

In addition, the two ends of the support plate 2 are provided with connecting grooves 21. The support plate 2 can be connected in series with other support plates of the same device through the connecting groove 21, and can be expanded into a conveying platform of any shape and position to form different conveying forms to meet the needs of different materials. Select the requirements of the environment.

When using this device specifically, the above-mentioned support plates can be integrated in series into a large-scale conveying platform, and several conveying plates can move quickly on the conveying platform to complete the purpose of logistics sorting. When driving the whole system, the distance of a single roller tooth is used as the indexing value of the coordinate axis, and the two-dimensional coordinate system is established on the plane where the conveying plate is located. The position of the center point of the conveying plate can be used as the real-time coordinate point of the conveying plate. When conveying is required, input the target position (X1, Y1) to which the conveying board will move to in the system interface, and the controller will stop the position (X0, Y0) and the target position (X1, Y1 ), calculate the displacements ΔX and ΔY that the conveyor plate needs to move in the X direction and Y direction, and control the rotation of the servo motors of the X-axis drive block and the Y-axis drive block according to the angle that the drive motor needs to rotate according to the distance of moving a single roller tooth The corresponding amount makes the conveying plate reach the target position in a right-angled way.

It should be noted that the amount of movement in the X direction can be completed first, or the amount of movement in the Y direction can be completed first, but the two can only choose one action, and the two directions cannot be moved at the same time to avoid the problem of tooth jamming. Because the roller teeth of the square platform structure mesh in one direction, the roller teeth in the other direction are just staggered. Only by ensuring that the driving block in the staggered direction of the roller teeth has no displacement, can the driving block in the meshing direction drive the conveyor plate normally.

The logistics sorting device and its driving method adopted in this embodiment can achieve the purpose of sorting and conveying through the unique structure of the cooperation between the transmission unit and the conveying plate, and can achieve the effect that the conveying plate moves quickly and runs smoothly, and has a simple structure. , accurate positioning, strong applicability, fast and stable operation, etc., and can also be combined into different material conveying lines to meet the requirements of different working environments.

The above content is only a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. limits.
