Description

Technical Field

[0001] The present invention relates to the technical field of pastry sorting, and more specifically, to a detection device for pastry sorting. Background Art

[0002] Pastries are a major part of cooking. The grain processing technology has developed from pestles, stone grinding basins, rods, pestles, etc. to stone mills. With the production of oil, seasonings and the use of bronze cookware, fried and steamed pastries emerged at that time, and bronze cookware similar to frying pans could be used for baking pastries.

[0003] Currently, after pastries are packed into packaging bags, due to insufficient precision in the pastry production process, there is a certain height difference between some of the produced pastries and the standard pastries. Then the produced pastries are packed into packaging bags and filled with nitrogen. The amount of nitrogen filled into each packaging bag is constant. If the height of the pastry is lower than the standard pastry height, the height of the inflated packaging bag will decrease. However, currently, pastry sorting is mainly carried out by manual sorting or robotic arm sorting. Manual sorting will reduce the working efficiency of pastry sorting and the sorting accuracy of the sorting device. Although robotic arm sorting will improve the working efficiency of pastry sorting, the robotic arm is a high-precision machine. If the robotic arm fails, it will increase the maintenance difficulty of the sorting device. Summary of the Invention

[0015] Compared with the prior art, the advantages of the present invention are as follows:

[0016] 1. In the present invention, when the detector detects that the pastry does not meet the standard, the first controller will start the third driving motor and the fourth driving motor. The start of the third driving motor will cause the first rotating block to separate from the first connecting block and the second connecting block, thereby stopping the rotation of the second feeding component. The start of the fourth driving motor will ultimately cause the rectangular rotating plate to rotate by 90 degrees, thereby changing the direction of the pastry and allowing the pastry to be conveyed to the first receiving cavity through the rectangular feeding plate. This will cause multiple linkage effects among the detection component, the first feeding component, the separation component, the second feeding component, and the screening component. Moreover, by detecting the pastry with the detector, the accuracy of pastry detection will be improved, and then the screened pastries will be collected separately, thus providing convenience for the staff, further improving the automation degree of the detection device, and simultaneously improving the working efficiency of the detection device.

[0017] 2. In the present invention, starting the second driving motor will drive the first connecting block to rotate, thereby driving the first rotating block and the third rotating belt to rotate, and further driving the second conveyor belt in the second feeding component to rotate. Starting the third driving motor will cause the first rotating block to separate from the first connecting block and the second connecting block. This will cause linkage effects among the first feeding component, the separation component, and the second feeding component. The separation component plays a connecting role, enabling the first feeding component and the second feeding component to be rotationally connected. When the separation component separates from the two feeding components, the rotation of the second feeding component will stop. This avoids some components from running for a long time, thereby reducing the temperature inside the components, further increasing the service life of the components, and simultaneously reducing the maintenance difficulty.

[0018] 3. In the present invention, the first conveyor belt, the rectangular rotating plate, and the second conveyor belt form the first conveying path. The start of the fourth driving motor will ultimately cause the rectangular rotating plate to rotate by 90 degrees, thereby causing the first conveyor belt, the rectangular rotating plate, and the inclined surface conveyor plate to form the second conveying path. In this way, according to the detection result of the detector, the conveying path can be changed, so as to collect the screened pastries separately. At the same time, installing the first receiving cavity and the second receiving cavity between two rectangular support blocks can prevent the pastries from falling to the ground during the collection process, thereby providing convenience for the staff.

At the same time, an infrared detector is connected to the inner cavity of the lower end of the detector 301;

[0031] Please refer to Figure 9 , The screening component 6 includes a rectangular rotating plate 601. Connection blocks 602 are connected to both ends of the rectangular rotating plate 601. Rectangular moving blocks 603 are connected to the lower ends of each connection block 602. Placing grooves 604 are formed on the upper surface of each rectangular moving block 603. And a third threaded rod 605 is sleeved at the end of each rectangular moving block 603 away from the connection block 602. A first bevel gear 606 is connected to the lower end of each third threaded rod 605. A second bevel gear 607 is meshed with one end of the first bevel gear 606. A second rotating wheel 608 is connected to one end of the second bevel gear 607. A fifth rotating belt 609 is sleeved on the outer surface of the second rotating wheel 608. A third rotating wheel 610 is sleeved on the end of the fifth rotating belt 609 away from the second rotating wheel 608. A fourth driving motor 611 is connected to one end of the third rotating wheel 610. And the rectangular moving blocks 603 are installed in the inner cavity of the rectangular sliding groove. The diameter of the third rotating wheel 610 is a multiple of the diameter of the second rotating wheel 608. Both ends of the rectangular rotating plate 601 are arc-shaped, so as to be fitted with the first conveyor belt 104 and the second conveyor belt 506.

[0032] Please refer to Figure 1 、Figure 2 and Figure 3 , the lower end of the screening component 6 is connected to a first material receiving cavity 7, and one end of the second material conveying component 5 far from the screening component 6 is connected to a second material receiving cavity 8. One end of the first material receiving cavity 7 facing the second material conveying component 5 is connected to an inclined surface material conveying plate. When the rectangular rotating plate 601 rotates by ninety degrees, the rectangular rotating plate 601 and the inclined surface material conveying plate will form a rectangular material conveying plate.

[0033] Please refer to Figure 9 , above the rectangular moving block 603 is connected with a fifth driving motor 612. The output end of the fifth driving motor 612 is connected with a second circular rotating block 613. One end of the second circular rotating block 613 facing the rectangular rotating plate 601 is provided with a first connecting groove, and the first connecting groove is fitted with the connecting block 602.

[0034] Please refer to Figure 5 , the first material conveying component 1 includes a second driving motor 101. The output end of the second driving motor 101 is connected with a first rotating belt 102. Both ends of the first rotating belt 102 are sleeved with first rotating rollers 103. The outside of the first rotating rollers 103 is sleeved with a first conveyor belt 104. And both ends of the first rotating roller 103 far from the second driving motor 101 are connected with first connecting blocks 105. And the first connecting block 105 is composed of a cylinder and a rectangle. Both ends of the first rotating roller 103 are sleeved with the first rotating belt 102.

[0035] Specifically, by starting the second driving motor 101, the first connecting block 105 will be driven to rotate, thereby driving the first rotating block 407 and the third rotating belt 408 to rotate, and further driving the second conveyor belt 506 in the second material conveying component 5 to rotate. And starting the third driving motor 401 will separate the first rotating block 407 from the first connecting block 105 and the second connecting block 501. In this way, a linkage effect will be generated among the first material conveying component 1, the separating component 4 and the second material conveying component 5. And the separating component 4 plays a connecting role to rotatably connect the first material conveying component 1 and the second material conveying component 5. When the separating component 4 is separated from the two material conveying components, the second material conveying component 5 will stop rotating. This avoids the long-term operation of some components, thereby reducing the temperature inside the components, further increasing the service life of the components, and at the same time reducing the probability of the device malfunctioning, and further reducing the maintenance difficulty.

[0036] Please refer to Figure 6 and Figure 7 , the separating component 4 includes a third driving motor 401. The output end of the third driving motor 401 is sleeved with a second rotating belt 402. Both ends of the second rotating belt 402 are sleeved with second threaded rods 403. One end of each second threaded rod 403 far from the second rotating belt 402 is connected with a circular moving block 404.

[0037] Please refer to Figure 6 and Figure 7 As shown, one end of each circular moving block 404 is connected to a guide rod 405. One end of each circular moving block 404 away from the second threaded rod 403 is connected to an annular connecting block 406. One end of each annular connecting block 406 away from the circular moving block 404 is connected to a first rotating block 407. A third rotating belt 408 is sleeved outside the first rotating block 407. A connecting groove is formed on the surface of one end of the first rotating block 407 away from the annular connecting block 406. The connecting groove is fitted with the first connecting block 105. The annular connecting block 406 is rotatably connected to the first rotating block 407.

[0038] Please refer to Figure 8 As shown, the second feeding assembly 5 includes a second connecting block 501. One end of the second connecting block 501 is connected to a ratchet 502. A ratchet pawl 503 is connected to the outside of the ratchet 502.

[0039] Specifically, a first conveying path is formed by the first conveyor belt 104, the rectangular rotating plate 601 and the second conveyor belt 506. Starting the fourth driving motor 611 will ultimately cause the rectangular rotating plate 601 to rotate by 90 degrees, so that a second conveying path is formed by the first conveyor belt 104, the rectangular rotating plate 601 and the inclined conveying plate. In this way, according to the detection results of the detector 301, the conveying path can be changed, so that the screened pastries can be collected separately. At the same time, the first receiving cavity 7 and the second receiving cavity 8 are installed between two rectangular support blocks 2, which can prevent the pastries from falling to the ground during the collection process, thus providing convenience for the staff.

[0040] Please refer to Figure 8 As shown, a fourth rotating belt 504 is sleeved outside the end of the ratchet pawl 503 away from the second connecting block 501. The two inner cavities of the fourth rotating belt 504 are connected to a second rotating roller 505. A second conveyor belt 506 is sleeved on the outer surface of the second rotating roller 505. The structural composition of the second connecting block 501 is the same as that of the first connecting block 105. The second connecting block 501 is fitted with the connecting groove formed on the surface of the first rotating block 407 connected to the end away from the third driving motor 401.

[0041] Specifically, if the flour products are detected by the detector 301 not to meet the standards, the first controller 309 will start the third drive motor 401 and the fourth drive motor 611. The start of the third drive motor 401 will separate the first rotating block 407 from the first connecting block 105 and the second connecting block 501, thereby stopping the rotation of the second feeding assembly. The start of the fourth drive motor 611 will ultimately rotate the rectangular rotating plate 601 by 90 degrees, thereby changing the direction of the flour products and allowing the flour products to be conveyed to the first receiving cavity 7 through the rectangular feeding plate. This will cause multiple linkage effects among the detection assembly 3, the first feeding assembly 1, the separation assembly 4, the second feeding assembly 5, and the screening assembly 6, so as to separately collect the screened flour products, which provides convenience for the staff, improves the automation degree of the detection device, and simultaneously improves the working efficiency of the detection device.

[0042] Working principle: First, place the flour products to be sorted on the upper surface of the first conveyor belt 104, and then start the second drive motor 101 and the first drive motor 304. Starting the first drive motor 304 drives the first threaded rod 303 to rotate, thereby causing the lifting rod 302 to move downward along the first threaded rod 303, further driving the detector 301 to move downward, and driving the L-shaped trigger block 308 to move downward along the rectangular chute 307;

[0043] Starting the second drive motor 101 drives the first rotating belt 102 to rotate, thereby driving the first rotating roller 103 to rotate, further driving the first conveyor belt 104 to rotate, and driving the first connecting block 105 to rotate. The rotation of the first conveyor belt 104 drives the flour products to move forward, and the rotation of the first connecting block 105 drives the first rotating block 407 to rotate, thereby driving the third rotating belt 408 to rotate, further driving the second connecting block 501 in the second feeding assembly 5 to rotate. As the second connecting block 501 rotates, it drives the ratchet wheel 502 to rotate, thereby driving the pawl 503 to rotate, further driving the fourth rotating belt 504 to rotate. The rotation of the fourth rotating belt 504 drives the second rotating roller 505 to rotate, thereby driving the second conveyor belt 506 to rotate;

[0044] When the flour products move to directly below the detector 301, the lower surface of the lifting rod 302 contacts the upper surface of the limiting block 306, and the L-shaped trigger block 308 contacts the trigger groove. At this time, if the lower surface of the detector 301 contacts the upper surface of the flour products, the flour products will sequentially pass through the rectangular rotating plate 601 and the second conveyor belt 506, so that the flour products are conveyed into the inner cavity of the second receiving cavity 8. If the lower end of the detector 301 does not contact the upper surface of the flour products, the first controller 309 starts the third drive motor 401 and the fourth drive motor 611;

[0045] Moreover, starting the third drive motor 401 will drive the second rotating belt 402 to rotate, thereby driving the second threaded rod 403 to rotate, and further driving the circular moving block 404 to move along the guide rod 405 towards the third drive motor 401. As the circular moving block 404 moves, it will drive the annular connecting block 406 to move, thereby driving the first rotating block 407 and the third rotating belt 408 to move towards one end of the third drive motor 401;

[0046] Starting the fourth drive motor 611 will drive the third rotating wheel 610 to rotate, thereby driving the fifth rotating belt 609 to rotate, and further driving the second rotating wheel 608 to rotate. As the second rotating wheel 608 rotates, it will drive the second bevel gear 607 to rotate, thereby driving the first bevel gear 606 to rotate, and further driving the third threaded rod 605 to rotate. And the rotation of the third threaded rod 605 will drive the rectangular moving block 603 to move upward, thereby driving the connecting block 602 and the rectangular rotating plate 601 to move upward;

[0047] When the pastry moves to one end of the first conveyor belt 104 close to the rectangular rotating plate 601, it will separate the connecting groove from the first connecting block 105 and the second connecting block 501, thereby stopping the rotation of the second feeding assembly 5, and making the placement groove 604 coincide with the fifth drive motor 612 and the second circular rotating block 613. At this time, the fifth drive motor 612 will rotate 90 degrees, thereby driving the second circular rotating block 613 to rotate, and further driving the connecting block 602 and the rectangular rotating plate 601 to rotate 90 degrees, and connecting the rectangular rotating plate 601 to the inclined surface feeding plate. At this time, when the pastry continues to move forward, it will convey the pastries that do not meet the adjustment standard to the first collection cavity 7 through the rectangular feeding plate, and then perform the picking operation on the pastries according to the above steps until all the pastries have completed the picking operation, and thus end all operations.
