The sorting device provided by the embodiment of the invention completely adopts a motor driving mode, avoids dependence on an air source, and has wider application scenes.

Example two

Referring to fig. 11, the present embodiment also provides a sorting device, and the sorting device of the present embodiment is an improvement on the first embodiment, and the technical solution of the first embodiment also belongs to the embodiment, and will not be described again. The same reference numerals are used for the same components as in the first embodiment, and reference is made to the description of the first embodiment.

In this embodiment, the side stopper 127 is provided with a deceleration photosensor 133 for decelerating the conveyor belt 103.

Optionally, each delivery box shuttle conveying mechanism is provided with a deceleration photoelectric sensor 133 for controlling the deceleration operation of the conveying belts 103 at different picking stations respectively. When the delivery box triggers the deceleration photoelectric sensor 133, the conveyer belt 103 operates in a deceleration manner, and the delivery box is slowly conveyed to a corresponding picking station, so that the impact force on the arms of workers when the delivery box slides down is reduced.

In some embodiments, the picking apparatus further includes a controller to which the deceleration photosensor 133 and the drive motor 116 are respectively connected.

It should be noted that the controller is a PLC controller that is commonly used at present.

Specifically, the signal output end of the deceleration photoelectric sensor 133 is connected with the PLC controller, and when the shipment box triggers the deceleration photoelectric sensor 133, the controller controls the driving motor 116 to operate in a deceleration manner, so that the conveying belt 103 operates in a deceleration manner, the shipment box is slowly conveyed to a corresponding sorting station, and the impact force on the arm of a worker when the shipment box slides down is reduced.

It should be noted that, in the first embodiment, the motors of the delivery box roller conveyor 200, the jacking motor 101, the driving roller 122 and the mecanum wheel set 123 are also controlled by the PLC controller, for example, when the delivery box is conveyed onto the conveyor belt, the PLC controller starts the jacking motor 101 to drive the eccentric wheel 104 to rotate, so as to lift the conveyor belt 103, and then starts the driving motor 116 (for example, to rotate the driving motor 116 forward), so as to convey the delivery box to the picking station. For another example, when the picking is completed, the PLC controller controls the driving motor 116 to rotate reversely, so as to return the picked delivery box to the delivery box roller conveyor 200.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
