[0026] Reference Figure 1 , a mixing BIN device, comprising a controller, a support frame 1, and a receiving bin 5, a mixing barrel 4, a feeding trough 3, and a plurality of feeding bins 2 installed on the support frame 1 from bottom to top, wherein the plurality of feeding bins 2, the feeding trough 3, the mixing barrel 4, and the receiving bin 5 are connected with materials in sequence, and the bottom of each feeding bin 2 is provided with a first discharge port connected to the feeding trough 3, the bottom of the feeding trough 3 is provided with a second discharge port connected to the mixing barrel 4, and the bottom of the mixing barrel 4 is provided with a third discharge port connected to the receiving bin 5, a first baffle 21 capable of opening or closing the first discharge port is installed at the bottom of the feeding bin 2, a second baffle 31 capable of opening or closing the second discharge port is installed at the bottom of the feeding trough 3, and a third baffle 41 capable of opening or closing the third discharge port is installed at the bottom of the mixing barrel 4; the controller is used to control the opening and closing of each of the first baffles 21 respectively; the mixing barrel 4 is rotatably installed on the support frame 1.

[0027] Through the feeding bin 2, workpieces of different specifications are input into the mixing device according to the counting method of the system output signal. Different workpieces alternately fall from the feeding trough to the spiral feeding trough 3 to achieve preliminary mixing. Below the spiral feeding trough 3 is a mixing barrel 4, which is controlled by a rotary motor 43 to rotate. When the workpiece falls into the mixing barrel 4, the detector 42 detects the falling of the workpiece and sends a signal. After receiving the signal from the detector 42, the rotary motor 43 below starts to work and causes the mixing barrel 4 to start rotating. The workpiece will be mixed twice with the rotation of the mixing barrel 4. After the mixing is completed, the device will send a mixing completion signal to the system end for manual confirmation. After the manual confirmation is correct, the third baffle 41 below the mixing barrel 4 will open to discharge the material, and the receiving bin 5 can receive the discharge from the bottom of the mixing barrel 4. Different workpieces are uniformly mixed together by quantitative feeding at different feeding bins 2, alternating falling in the feeding trough 3, and shaking and mixing in the mixing barrel 4, which can ensure the accuracy and uniformity of the number of mixed workpieces.

[0028] Specifically, the mixed BIN device of the present scheme also includes a counter corresponding to each of the feeding bins 2. Each of the counters is installed on the feeding bin 2 and is used to calculate the number of workpieces entering the discharge chute 3. The accuracy of the number of mixed workpieces can be ensured through the counting-type feeding at the feeding bin 2.

[0029] Specifically, the controller includes a signal receiving device 22 corresponding to each of the feeding bins 2 , and each of the signal receiving devices 22 is used to control each of the first baffles 21 to automatically open or close.

[0030] Specifically, the mixing BIN device of the present embodiment also includes a rotary motor 43 installed on the mixing barrel 4, and the rotary motor 43 is used to control the rotation of the mixing barrel 4; the controller also includes a detector 42 installed on the mixing barrel 4 and electrically connected to the rotary motor 43, and the detector 42 is used to sense the workpiece falling into the mixing barrel 4. When the detector 42 senses the workpiece, the rotary motor 43 is started.

[0031] Specifically, the inner wall of the mixing barrel 4 is covered with a cushion pad, which is elastic. When the mixing barrel 4 rotates to mix the workpieces, when the workpieces collide with the inner wall of the mixing barrel 4 in the mixing barrel 4, the cushion pad has a cushioning effect on the workpieces, thereby preventing the workpieces from being damaged by colliding with the inner wall of the mixing barrel 4.

[0032] Specifically, the feeding bin 2 is funnel-shaped, so that the workpiece can fall to the first discharge port and enter the discharge chute 3 .

[0033] Specifically, the inner wall of the feeding trough 3 is provided with a spiral groove 32, and each of the first discharge ports and the second discharge port is connected by the spiral groove 32. The number of the spiral grooves 32 can correspond to the first discharge ports one by one, and different workpieces can fall alternately in the feeding trough 3 along the spiral grooves 32 corresponding to each first discharge port, and be mixed at the second discharge port. The setting of the spiral groove 32 facilitates the smooth guidance of the workpiece to the bottom of the feeding trough 3 and the pre-mixing before entering the mixing barrel 4 from the second discharge port. At the same time, when the workpiece slides along the spiral groove 32 to the bottom of the feeding trough 3, it can avoid the situation where the workpiece directly falls from the first discharge port to the bottom of the feeding trough 3, and the workpiece will not be damaged due to bumps and the like.

[0034] Specifically, the feed chute 3 is bowl-shaped.

[0035] The mixed BIN scheme with the highest shipment rate is calculated according to the workpiece output information. According to the mixed BIN scheme with the highest shipment rate, different feeding bins 2 are controlled to count and feed materials according to the calculated ratio. The mixing device mixes the workpieces together by counting feeding at the feeding bin 2, alternating falling in the feeding trough 3, and shaking mixing in the mixing barrel 4, so as to ensure the accuracy and uniformity of the number of mixed workpieces.

[0036] For other contents of the mixed BIN device described in the present invention, please refer to the prior art and will not be repeated here.

[0037] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
