Currently, automated sorting and unloading mechanisms, widely used in equipment, have a promising market prospect.
[0003] In the current technology, steel pipes are sorted manually for parts from the same work order before being transported together to the next process. Summary of the Invention
[0004] This invention proposes an automatic sorting and unloading mechanism to improve the sorting efficiency of workpieces on the same work order and to automatically unload them into turnover boxes.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automatic sorting and unloading mechanism includes: a drive mechanism, a material box mechanism, an unloading mechanism, a turnover box, and a base; the base is equipped with a drive mechanism that provides rotational power, which drives the material box mechanism to move to the inlet and the unloading position, and writes and reads data through an RFID reader / writer head; the unloading mechanism is driven by a cylinder to push the material box to flip over, and pours the workpieces of the same work order in the material box into the turnover box to complete the unloading.
[0006] The drive mechanism includes a servo motor, a reducer, a motor bracket, a coupling, a drive shaft, a bearing housing, a sprocket, a chain, and a driven shaft. The servo motor is fixed to the input end of the reducer with screws. The output flange of the reducer is fixed to the motor bracket, which is fixed to a base. The output shaft of the reducer is connected to the drive shaft via a coupling to transmit power. The bearing housing is fixed to the base. The drive shaft passes through the bearing bore of the bearing housing and engages with the sprocket, driving the sprocket to rotate. The sprocket and chain are installed together; the rotation of the sprocket drives the chain, which in turn drives the driven shaft to rotate.
[0007] The material box mechanism includes a material box lever, a material box rotating shaft, a material box rotating bearing, a material box rotating bearing bracket, a material box rolling bearing, a material box, an RFID chip, and an RFID reader / writer. There are two material box rotating bearing brackets, mounted on the chain on both sides, moving with the chain. The material box rotating bearings are mounted on these brackets. Two material box rotating shafts are welded to the center of the two end faces of the material box, rotating together with the material box. Two material box rolling bearings are inserted into the two rotating shafts and mounted on the two end faces of the material box with screws. When the material box moves below the hopper, the rolling bearings roll on the base to reduce the stress on the chain. The material box lever has a square hole that connects to the rotating shaft on one side, allowing it to rotate together. An RFID chip is installed on the rotating shaft on the other side. The material box lever, rotating shaft, and material box can rotate together and move with the chain.
[0008] The unloading mechanism includes an unloading bracket, a lever cylinder, a lever cylinder bracket, a cylinder connecting block, a guide rail slider, a guide rail mounting plate, a cylinder lug, a lever rotation cylinder, a cylinder rod hinge ring, a lever, a hinge shaft, and a lever bearing. The unloading bracket is mounted on a base, the lever cylinder is mounted on the lever cylinder bracket, and the lever cylinder bracket is fixed to the unloading bracket with screws. The guide rail fixed end of the guide rail slider is mounted on the unloading bracket, the guide rail mounting plate is fixed to the slider of the guide rail slider, and the cylinder connecting block is connected to the guide rail. On the mounting plate, the cylinder connecting block is connected to the piston rod of the lever cylinder. The lever cylinder can drive the guide rail mounting plate to move. The cylinder ear seat is connected to the bottom of the lever rotary cylinder and is mounted on the guide rail mounting plate. The lever bearing is installed on one end of the lever. The lever and the hinge shaft are hinged together. The hinge shaft is fixed on the guide rail mounting plate. The other end of the lever is hinged together with the cylinder rod hinge ring. The cylinder rod hinge ring is connected to the piston of the lever rotary cylinder. The extension and retraction of the piston of the lever rotary cylinder can drive the lever to rotate.
[0009] Compared with the prior art, the present invention has the following advantages: 1. In this invention, a servo drive chain is used, and the material box can be accurately moved to the loading position, unloading position, and RFID reading and writing position. Through RFID, it can be known which work order is in each material box, and the unloading of the workpieces of the required work order can be completed automatically.
[0010] In summary, the servo motor provides power, the drive shaft drives the sprocket to rotate, and the chain moves the material box to the required position. The RIFD reads and writes information. When unloading, the lever rotation cylinder extends, pushing the lever to the horizontal. At this time, the lever bearing contacts the material box lever and rotates it, thus completing the flipping of the material box and pouring the workpiece into the turnover box.

The material box rotating bearing 25 is mounted on the material box rotating bearing brackets 26. There are two material box rotating shafts 24, each welded to the center of the end faces of the material box 28, rotating together with the material box 28. Two roller bearings 27 are inserted into two roller shafts 24 and mounted on the two end faces of roller 28 with screws. When roller 28 moves under the hopper, roller bearings 27 roll on base 10 to reduce the force on chain 8. Roller lever 23 has a square hole and is connected to roller shaft 24 on one side to rotate together. RFID chip 29 is installed on roller shaft 24 on the other side. In this way, roller lever 23, roller shaft 24 and roller 28 can rotate together and move with chain.
[0019] The unloading mechanism includes an unloading bracket 11, a lever cylinder 12, a lever cylinder bracket 13, a cylinder connecting block 14, a guide rail slider 15, a guide rail mounting plate 16, a cylinder lug 17, a lever rotation cylinder 18, a cylinder rod hinge ring 19, a lever 20, a hinge shaft 21, and a lever bearing 22. The unloading bracket 11 is mounted on a base 10, the lever cylinder 12 is mounted on the lever cylinder bracket 13, and the lever cylinder bracket 13 is fixed to the unloading bracket 11 with screws. The guide rail fixed end of the guide rail slider 15 is mounted on the unloading bracket 11, the guide rail mounting plate 16 is fixed to the slider of the guide rail slider 15, and the cylinder connecting block 14 is connected to the guide rail. The guide rail mounting plate 16 is mounted on the cylinder mounting block 14, and the cylinder connecting block 14 is connected to the piston rod of the lever cylinder 12.

In this way, the extension and retraction of the piston of the lever rotating cylinder 18 can drive the lever 20 to rotate.
[0020] It should be noted that: driven by servo motor 1, the drive shaft 5 rotates, which in turn drives the sprocket 7 to rotate, thereby moving the chain 7 and the material box 28 to the required loading position, unloading position, and RFID reading / writing position. The lever cylinder 12 extends, driving... Figure 2 When the lever 20 in the indicated state is activated, it causes the material box 28 to flip, completing the unloading process.
[0021] Furthermore, this invention facilitates subsequent automation upgrades, allowing a robotic arm to place workpieces from the same work order into the same material box and record data, while unloading the material when the box is full.
[0022] The functional principle of this invention can be explained through the following operational methods: This invention involves placing cut steel pipes from the same work order into the same material box. A servo motor 1 drives a sprocket 7 to rotate, and through the sprocket and chain rotating pair, the material box 28 is sent to the required loading position, RFID reading / writing position, and unloading position. After the system identifies that the material box 28 containing steel pipes from the same work order is full, the material box 28 is sent to the unloading position. At this time, the lever cylinder 18 extends, driving the lever 20 to rotate to a horizontal position. The piston of the push rod cylinder 12 extends, driving the lever 20 to move downward. The lever bearing 22 on the lever 20 contacts the material box lever 23 and drives it to rotate, thereby driving the material box 28 to rotate and pouring the workpiece into the turnover box 9. The turnover box is then removed manually or by a robot and proceeded to the next process. This cycle is repeated to complete the sorting and unloading.
