In this embodiment, a locking member 204 is disposed between the rack 200 and the bin 300. The lock 204 is switchable between a locked state and an unlocked state. When the locking member 204 is in the locked state, the bin 300 is positioned within the frame 200 and is fixedly coupled to the frame 200. When the locking member 204 is in the unlocked state, the bin 300 can be pulled out of the rack 200. In this manner, the bin 300 may be securely fixed within the frame 200. It will be appreciated that in other embodiments, the locking member 204 may be omitted when the fastening strength is not required.

In this embodiment, the number of locking members 204 is two. In the drawing direction of the magazine 300, two locking members 204 in a locked state are located at front and rear edges of the same side of the magazine 300. In this manner, the cartridge 300 may be more securely fastened within the housing 200. It will be appreciated that in other embodiments, the lock 204 may be provided in one or more pieces. In this embodiment, the locking member 204 includes a lock base and a locking tongue controlled by a cylinder. The cylinder is in the out state, the lock tongue is inserted on the lock seat, and at this time, the locking piece 204 is in the locking state.

When the automatic loading and unloading buffer device 10 is used for loading, the trays 12 can be loaded onto the plurality of loading bins 300a, then the machine is started, since each loading bin 300a is provided with the lifting structure 500 and the tray dividing structure 600, the lifting structure 500 and the tray dividing structure 600 cooperate to move the plurality of trays 12 stacked in the loading bin 300a to the tray dividing structure 600 one by one, and the loading carrying structure 700a can carry the trays 12 on the plurality of tray dividing structures 600 away, so that under the cooperation of the lifting structure 500 and the tray dividing structure 600, the loading carrying structure 700a can carry the tray of one loading bin (the first loading bin) 300a first time, after the tray carrying of the loading bin 300a is completed, the loading carrying structure 700a can carry the tray of the other loading bin (the second loading bin) 300a again, at this time, the worker can pull out the empty first loading bin, and then push the first loading bin onto the full tray, and then push the first loading bin 200 into the machine frame for one time. That is, the automatic feeding and discharging buffer device 10 can perform manual feeding in one feeding bin 300a, and the other feeding bin 300a can work normally without stopping (without suspending the device), so that the feeding efficiency is high.

When the automatic discharging buffer device 10 is used for discharging, as each discharging bin 300b is provided with the jacking structure 500 and the separating disc structure 600, the jacking structure 500 and the separating disc structure 600 can be matched to move the trays 12 positioned on the separating disc structure 600 into the discharging bins 300b one by one, and the discharging carrying structure 700b can be matched with the jacking structure 500 and the separating disc structure 600 to firstly discharge in one discharging bin (the first discharging bin) 300b, and after the discharging bin 300b is full, the discharging carrying structure 700b is further discharged in the other discharging bin (the second discharging bin) 300b, at this time, a worker can pull out the first discharging bin full of the material, empty the first discharging bin, and then push the first discharging bin into the frame 200 to perform the next discharging. That is, the automatic discharging buffer device 10 can perform the emptying of one discharging bin 300b, and the other discharging bin 300b can perform the normal discharging without stopping the machine (without suspending the device), thereby having higher discharging efficiency.

In this embodiment, the jacking structure 500 is disposed on the frame 200 and is located at the lower end of the bin 300. Specifically, in the present embodiment, the lifting structure 500 is a linear stepper motor. Therefore, the automatic feeding and discharging buffer device 10 has lower cost. It is understood that in other embodiments, the lifting structure 500 may be a linear module. In this embodiment, the tray structure 600 is disposed on the rack 200 and is located at the upper end of the bin 300. The carrying structure 700 is disposed on the top plate 220. Thus, the automatic feeding and discharging buffer device 10 has a compact structure.

In this embodiment, the magazine 300 has a tray therein for holding trays 12. The jacking mechanism 500 is used to control the movement of the trays toward and away from the split disc mechanism 600.

The loading bin 300 has a first tray dividing position, a first tray dividing waiting position, and a first origin position, the first tray dividing position being closer to the tray dividing structure 600 than the first tray dividing waiting position, the first tray dividing waiting position being closer to the tray dividing structure 600 than the first origin position. The first tray dividing waiting position is provided with a first predetermined position sensor. The first disc separating position is provided with a disc-free detection sensor. The first pre-positioning sensor is in communication with the jacking structure 500. During the movement of the tray toward the tray dividing structure 600, after the first pre-positioning sensor detects the end tray 12, the tray moves by a distance between the first tray dividing waiting position and the first tray dividing position so that the end tray 12 reaches the first tray dividing position. After the tray separating structure 600 is received by the end tray 12, the jacking structure 500 drives the tray to move away from the tray separating structure 600. During movement of the tray away from the tray separating structure 600, the movement of the tray is stopped after the end tray 12 or tray leaves the detection range of the first predetermined sensor. The diskless detection sensor is communicatively coupled to the jacking structure 500. When the tray reaches the first tray separating position and the tray 12 cannot be detected by the tray-free detection sensor, the tray 12 is controlled to move away from the tray separating structure 600 and to the first origin position.

The discharging bin 300 has a second tray dividing position, a second tray dividing waiting position, and a second origin position. The second split position is closer to the split structure 600 than the second split waiting position. The second sub-disc waiting position is closer to the sub-disc structure 600 than the second origin position. The second sub-tray waiting position is provided with a second predetermined position sensor. A full disc detection sensor is arranged between the second disc dividing waiting position and the second original position. The second predetermined position sensor is communicatively coupled to the jacking structure 500. During movement of the tray toward the tray separation structure 600, after the second pre-positioning sensor detects the tray or the end tray 12 positioned on the tray, the tray moves a separation distance between the second tray waiting position and the second tray separation position such that the tray or the end tray 12 receives a single tray 12 positioned on the tray separation structure 600. During movement of the tray away from the split tray structure 600, the tray stops moving after the end tray 12 leaves the detection range of the second pre-positioning sensor. The full tray detection sensor is in communication with the jacking structure 500. When the full tray detection sensor detects the tray during the movement of the tray away from the tray separating structure 600, the tray is controlled to move to the second origin position.

In this embodiment, each silo 300 is also configured with a positioning structure 800. The positioning structure 800 is used for positioning the trays 12 located on the tray dividing structure 600. That is, in this embodiment, the tray separating station and the positioning station of the tray 12 are the same station. Therefore, the automatic feeding and discharging buffer device 10 can be more compact in structure.
