[0042] The embodiments of the present invention will be further described below with reference to the accompanying drawings:

[0043] Depend on Figure 1 Combination Figures 2-7 As shown, a vertical microcontroller includes a frame 1, and further includes:

[0044] Feeding device 2, mounted on frame 1, is used for horizontal feeding of materials;

[0045] A multi-plate conveyor 3, mounted on a frame 1, is used to receive materials conveyed by a feeding device 2. The multi-plate conveyor 3 includes a first multi-plate belt 31, which has multiple first cavities 311 for accommodating the horizontal feeding of the feeding device 2. The first multi-plate belt 31 has a first position for receiving materials in different first cavities 311 by moving sequentially, and a second position for accelerating to the next process after receiving materials.

[0046] A variable torque conveyor 4, mounted on the frame 1, is used to receive vertical materials from the multi-piece conveyor 3, merging and conveying them to the next process for packaging. The advantages of this invention are that it incorporates a multi-piece conveyor system, collecting and counting materials through a first cavity, then merging them via the variable torque conveyor for packaging. This results in a simple structure, reliable counting, and facilitates the feeding and packaging of multiple pieces of material.

[0047] The aforementioned multi-piece conveying device 3 includes:

[0048] The first counting drive unit 32 is connected to the first counting belt 31 and is used to drive the first counting belt 31 to reciprocate in a circumferential direction.

[0049] The second counting belt 33 is provided with a second cavity 331 for receiving the horizontal feed of the feeding device 2. There are multiple second cavities 331. The second counting belt 33 has a first position when different second cavities 331 receive the material and a second position when the material is received and the material is accelerated to the next process.

[0050] The second counting drive unit 34 is connected to the second counting belt 33 and is used to drive the second counting belt 33 to reciprocate in a circumferential direction. In this invention, the first and second counting belts are arranged in parallel. When the first counting belt feeds material one by one, the first cavity receives material one by one. After the first cavity has finished receiving material, the first counting drive unit drives the first counting belt to accelerate, transporting the first cavity and the vertical material inside to the torque converter. At this time, the second counting belt feeds material one by one through the second cavity. That is, the first and second counting belts move relatively independently, which facilitates reliable and fast material reception. Moreover, when material is placed in different first and second cavities, the second cavity can immediately receive material when the first cavity discharges, which facilitates rapid product processing, good product synchronization, and high processing efficiency.

[0051] The first counting belt 31 is provided with a plurality of first sheets 312, and adjacent first sheets 312 cooperate with each other to form the first cavity 311. The second counting belt 33 is provided with a plurality of second sheets 332, and adjacent second sheets 332 cooperate with each other to form the second cavity 331. The second cavity 331 of the second counting belt 33 is in the receiving position when the first cavity 311 of the first counting belt 31 is in the second position of accelerated movement. Specifically, the first sheet 312 has a first state of being horizontally positioned for receiving material and a second position of being flipped vertically by the first counting belt 31. The second sheet 332 has a first state of being horizontally positioned for receiving material and a second position of being flipped vertically by the second counting belt 33. The first counting drive 32 drives the first counting belt 31 to move with the first counting shaft 35 as the drive shaft, and the second counting drive 34 drives the second counting belt 33 to move with the second counting shaft 36 as the drive shaft. The second counting shaft 36 is the driven shaft of the first counting belt 31 and is used to support the first counting belt 31. In this invention, the first counting shaft only drives the first counting belt to move and also serves as the support shaft for the second counting belt. That is, the first counting shaft drives the first counting belt to move through a spline, and a bearing is provided on the second counting shaft, with the first counting belt sleeved on the bearing. Of course, the second counting shaft is also used to drive the second counting belt to rotate, and the other end of the second counting belt is supported by the first counting shaft. In actual production, each cavity can be set with 1, 2, 3 or more materials. Of course, the number of boxes to be packed can also be set according to the time requirements, such as the first cavity being filled with 2 materials and the remaining first cavities being filled with 3 materials. All of these can be reliably counted by the program.

There are multiple torque converter boxes 441.

[0057] The second torque guide 45 is located in the discharge direction of the torque box 441 and is used to receive the material on the torque box 441 and then transport it to the next process for packaging after merging.

[0058] The second torque-changing conveying mechanism 46 is used to push the vertical material in the first torque-changing guide trough 42 into the torque-changing material box 441, and push the material in the torque-changing material box 441 into the second torque-changing guide trough 45. Each first torque-changing guide trough has a first channel corresponding to a first cavity, and multiple first cavities can be configured to correspond to the first torque-changing guide troughs, allowing the materials in multiple first cavities to merge for the first time within the first torque-changing guide trough. Different first torque-changing guide troughs converge into different torque-changing material boxes, and then the torque-changing drive component causes the torque-changing material boxes to converge towards the center and be fed into the second torque-changing guide trough for a second merging, used for product packaging.

[0059] There are multiple first torque-changing guide channels 42, each including multiple first partitions 421. The first partitions 421 divide the space on the first torque-changing guide channel 42 into multiple first channels 422 corresponding to the multi-piece conveying device 3. Each first torque-changing guide channel 42 has a second channel 423 corresponding to the torque-changing material box 441, and all first channels 422 are connected to the second channels 423. Specifically, the second torque-changing guide channel 45 has multiple second partitions 451, which divide the space on the second torque-changing guide channel 45 into multiple third channels 452 corresponding to the torque-changing material box 441. The second torque-changing guide channel 45 is detachably connected to the torque-changing frame 41. This structure allows multiple pieces of material to be reliably combined for boxing. Specifically, the final boxing quantity can be determined by varying the amount of material in the first / second cavity, and only the second torque-changing guide channel needs to be replaced to adapt the product for boxing and counting packaging of different products.

[0060] The first torque-changing conveying mechanism 43 includes a first torque-changing conveying pusher plate 431 and a first torque-changing conveying drive assembly 432. The first torque-changing conveying pusher plate 431 is connected to the first torque-changing conveying drive assembly 432 and is driven by the first torque-changing conveying drive assembly 432 to move vertically and / or horizontally. The second torque-changing conveying mechanism 46 includes a second torque-changing conveying pusher plate 461 and a second torque-changing conveying drive assembly 462. The second torque-changing conveying pusher plate 461 is connected to the second torque-changing conveying drive assembly 462 and is driven by the second torque-changing conveying drive assembly 462 to move vertically and / or horizontally. This structure makes material movement convenient and reliable.

[0061] The feeding device 2 includes:

[0062] The waste removal mechanism 21 is oscillating and used to remove waste materials;

[0063] The first feeding mechanism 22 is used to receive qualified materials from the rejection mechanism 21 and feed them horizontally.

[0064] The second feeding mechanism 23 includes two feeding conveyor belts 231 arranged vertically, and a material channel 232 for material to pass through is formed between the two feeding conveyor belts 231.

[0065] A protective plate 24 is located behind the discharge direction of the second feeding mechanism 23 to protect the outside of the conveyor device 3 during horizontal feeding; the protective plate 24 is arc-shaped. The protective plate can limit the material from falling when it is flipped horizontally. The waste removal mechanism is oscillating for easy removal of waste.

[0066] It also includes a discharge device 5, which is located behind the torque converter 4 and is used to receive the material conveyed by the torque converter 4. The discharge device 5 includes:
