Description

Technical Field

[0001] The utility model relates to the technical field of biscuit detection, in particular to a biscuit detection device. Background Art

[0002] Traditional biscuit packaging is manual packaging. If biscuits are broken or incomplete during the handling process, they can be observed with the naked eye and then processed.

[0003] For example, a biscuit detection and rejection device with the announcement number "CN210676001U" includes a biscuit conveyor belt, a camera, a rejection module, a camera mounting frame, a rejection module mounting frame and a light shield. The camera mounting frame is provided with a projection light bar that cooperates with the camera. The rejection module includes a motor, a cross-impeller connected to the output shaft of the motor, a first collecting cylinder arranged on the positive side of the cross-impeller, and a grabbing robot arranged on one side of the first collecting cylinder and cooperates with the first collecting cylinder. However, when the device detects biscuits, it can only detect one side of the biscuit. If the other side of the biscuit is to be detected, the biscuit that has been detected needs to be transported to the device again, and then the other side of the biscuit is re-detected. The working efficiency of the device is low. At the same time, when the device rejects unqualified biscuits, it uses the rotation of the cross-impeller to reject the biscuit. If the biscuit is offset in the placement slot, the cross-impeller will not be able to contact the biscuit or crush the biscuit, and the device cannot complete the biscuit rejection work normally.

The output shaft of the first motor 402 is rotatably connected to the first shell 401 through a bearing, and the output end of the first motor 402 is fixedly connected to a connecting rod 403. The rotation of the output shaft of the first motor 402 can drive the connecting rod 4003 to rotate. The end of the connecting rod 403 is rotatably connected to the slider 404 through a pin shaft. The slider 404 is slidably connected to the first straight rod 405. The rotation of the connecting rod 403 can drive the slider 404 to slide inside the first straight rod 405, thereby driving the first straight rod 405 to move laterally.

[0031] Working principle:

[0032] When the biscuits need to be inspected, the biscuits are first transported to the upper left side of the first conveyor belt 3 at equal intervals, and then the first conveyor belt 3, the second conveyor belt 6, the first photoelectric sensor 9 and the second photoelectric sensor 11 are started to make the first conveyor belt 3 and the second conveyor belt 6 move at a uniform speed, so that the time for each biscuit to reach the pushing structure 7 after inspection is the same, preparing for the biscuit inspection work.

[0033] After starting the first conveyor belt 3, the biscuits are transported to the right. When the biscuits are transported to the bottom of the first photoelectric sensor 9, the first photoelectric sensor 9 can use the function of converting infrared receiving signals into electrical signals to detect the color of the biscuit surface, detect biscuits with abnormal color, and then continue to transport the biscuits to the right.

[0034] Cookie flipping work:

[0035] When the biscuits leave the first conveyor belt 3, they will slide onto the curved plate 408, and then the external power supply of the first motor 402 will be turned on, and the first motor 402 will be started to drive the connecting rod 403 to rotate. The rotation of the connecting rod 403 drives the slider 404 to slide inside the first straight rod 405, and at the same time, the slider 404 drives the first straight rod 405 to move left and right. The left and right movement of the first straight rod 405 drives the first rack 406 to move left and right. The left and right movement of the first rack 406 drives the gear 407 to rotate back and forth. The reciprocating rotation of the gear 407 drives the curved plate 408 to swing back and forth, turning over the biscuits above the curved plate 408, and making the biscuits fall onto the second conveyor belt 6, and the biscuits continue to be transported to the right.

[0036] When the biscuit is conveyed to the bottom of the second photoelectric sensor 11, the second photoelectric sensor 11 detects the other side of the biscuit and then continues to convey the biscuit to the right.

[0037] When the first photoelectric sensor 9 or the second photoelectric sensor 11 detects that the biscuits are unqualified, they will output a signal to the pushing structure 7. Since the time it takes for each biscuit to pass through the photoelectric sensor and reach the pushing structure 7 is the same, the pushing structure 7 receives the signal and then starts after the time has passed. At this time, the unqualified biscuits just move in front of the pushing structure 7, and the pushing structure 7 starts to remove the unqualified biscuits. If the biscuits are qualified, the photoelectric sensor will not send a signal, and the pushing structure 7 will not start before the qualified biscuits pass through the pushing structure 7, so that the qualified biscuits can continue to be transported to the right.

[0038] Remove unqualified cookies:

[0039] When unqualified biscuits are detected and transported to the front of the pushing structure 7, the external power supply of the second motor 702 is connected, and the second motor 702 is started to drive the disc 703 to rotate, and the rotation of the disc 703 drives the cylinder 704 to rotate, and the rotation of the cylinder 704 drives the second straight rod 705 to move, and the movement of the second straight rod 705 drives the incomplete gear 706 to rotate back and forth, and the reciprocating rotation of the incomplete gear 706 drives the second rack 707 to move back and forth, and the reciprocating movement of the second rack 707 drives the push rod 708 to move back and forth. When the push rod 708 moves forward, the unqualified biscuits are pushed into the collection box 12, so that the unqualified biscuits are removed.
