In the above embodiment, the feeding conveyor 110 and the discharging conveyor 210 may be a conveyor belt or a conveyor sprocket, which moves the frame under the action of friction force by contacting the frame.

It can be seen that, in the feeding and discharging mechanism of the present application, two feeding conveying members 110 disposed oppositely are used for driving the feeding of the material frame, and two discharging conveying members 210 disposed oppositely are used for driving the discharging of the material frame, and a first lifting member 310 is disposed in a first mounting space 120 at a discharging end of the feeding conveying member 110, and a second lifting member 320 is disposed in a second mounting space 220 at a feeding end of the discharging conveying member 210, so that the first lifting member 310 and the second lifting member 320 form a lifting and transferring channel, and the material frame can be transferred to the discharging conveying member 210 by a manner that the material frame can be separated from the feeding conveying member 110 through a material pushing structure 400, in this process, the feeding conveying member 110 and the discharging conveying member 210 do not need to be stopped, the efficiency of the whole feeding and discharging material pushing mechanism is improved, and the material frame can be transferred from the feeding structure 100 to the discharging structure 200 only by disposing the material pushing structure 400, the first lifting member 310 and the second lifting member 320, which is simple in structure and low in cost.

That is, after the first lifting member 310 and the second lifting member 320 are lifted, the first lifting member 310, the second lifting member 320 and the conveying member 330 are located on the same plane, so that the frame can be moved from the first lifting member 310 to the second lifting member 320 through the conveying member 330.

It can be understood that, in some embodiments, the distance between the discharge end of the feeding conveyor 110 and the feed end of the discharging conveyor 210 may be longer, the first lifting member 310 is disposed in the lower first installation space 120 formed by the feeding conveyor 110, and the second lifting member 320 is disposed in the second installation space 220 formed by the discharging conveyor 210, so that the distance between the first lifting member 310 and the second lifting member 320 may be longer, and therefore, in order to enable the material frame on the first lifting member 310 to stably move from the first lifting member 310 to the second lifting member 320, the material frame may be moved to the second lifting member 320 through the conveying member 330 by disposing the conveying member 330 between the first lifting member 310 and the second lifting member 320.

Further, rollers 350 that rotate toward the feeding end of the lower feeding conveyor 210 may be respectively disposed on the end surfaces of the first lifting member 310, the second lifting member 320, and the conveyor 330.

Specifically, referring to fig. 3, the first and

second lifters

310 and 320 may be lifting cylinders, a mounting plate 340 may be disposed on driving ends of the first and

second lifters

310 and 320, and a plurality of rollers 350 rotating in a feeding end direction may be disposed on the mounting plate 340 (e.g., when the feeding conveyor 110 and the discharging conveyor 210 are juxtaposed, a rotating direction of the rollers 350 is perpendicular to a conveying direction of the feeding conveyor 110 and the discharging conveyor 210).

In practical use, after the material frame is conveyed to the area where the first lifting member 310 is located (i.e. the discharging end of the material conveying member 110), the first lifting member 310 and the second lifting member 320 are lifted at the same time, and then the material frame can be smoothly moved from the first lifting member 310 to the second lifting member 320 through the conveying member 330 under the action of the material pushing structure 400 and the roller 350.

The pushing driving member 410 may be a pushing cylinder.

The pushing structure 400 has a simple structure and is convenient to assemble, and only the pushing driving member 410 needs to be fixed on one side of the first lifting member 310.

Referring to fig. 1, the loading and unloading mechanism may further include a first lifting structure 500, and the first lifting structure 500 is disposed in the first installation space 120 and located in the workpiece loading area. Wherein, the feeding area of the workpiece can be determined according to the position of the external workpiece transfer mechanism.

With first jacking structure 500 matched with, the bottom of material frame corresponds first jacking structure 500 and is provided with the jacking hole.

Specifically, when the material frame moves to the workpiece loading area along with the loading conveyor 110, the first jacking structure 500 is lifted, and jacks up the workpiece loaded in the material frame through a jacking hole arranged on the material frame, so that the workpiece can be transferred by an external transfer mechanism.

Wherein, the first jacking structure 500 can adopt a screw motor or a jacking cylinder. For example, when a plurality of workpieces are stacked in the material frame, the first lifting structure 500 may employ a screw motor so as to lift each workpiece to a feeding height in sequence; when the material frame is loaded with only one workpiece, the first jacking structure 500 may employ a jacking cylinder.

Further, in some embodiments, the loading and unloading mechanism may further include a second jacking structure 600, the second jacking structure 600 may be the same as the first jacking structure 500, and the second jacking structure 600 is disposed in the first installation space 120 or the second installation space 220 and located in the workpiece unloading area. The second jacking structure 600 is disposed in the first installation space 120 or the second installation space 220, and can be determined according to the position of the external workpiece blanking transfer mechanism.

For example, when the external workpiece discharging transfer mechanism is disposed at one side of the feeding conveyor 110, the second jacking structure 600 may be disposed in the first installation space 120; when the external workpiece blanking transfer mechanism is disposed at one side of the blanking conveyer 210, the second jacking structure 600 may be disposed in the second installation space 220.

It will be appreciated that the workpiece blanking region may generally be disposed downstream of the workpiece loading region. By the method, after the workpiece to be processed in the material frame is loaded, the material frame just empty can be moved to the workpiece discharging area to load the processed workpiece.

Further, an inclined portion 730 may be disposed at an end portion of the striker plate 720 on a side close to the upstream, and the inclined portion 730 can prevent the striker plate 720 from interfering with the material frame when being lifted.

Referring to fig. 1, the two sides of the feeding conveyor 110 facing away from each other and the two sides of the discharging conveyor 210 facing away from each other may be further provided with a guide member along the conveying direction of the frame, respectively, and the guide members are used for guiding the movement of the frame. Wherein the guide may be a guide bar 900.
