Description

Technical Field

[0001] The invention discloses a thin product conveying device with a detection groove, belonging to the technical field of conveyor belts. Background Art

[0002] After being removed from the hand mold, the gloves fall onto the conveyor belt. During the process of conveying the gloves on the conveyor belt, a photoelectric switch is needed to detect the gloves. When the photoelectric switch detects the gloves, the conveyor belt stops running to facilitate the robot and other equipment to clamp the gloves on the conveyor belt to the next process.

[0003] Since the surface of thin products such as gloves is very close to the conveyor belt, the distance between the conveyor belt and the gloves detected by the photoelectric switch is very small. Therefore, it is not easy for the photoelectric switch to distinguish whether the detected product is on the conveyor belt during detection, and it is easy to make a false detection, which affects the normal progress of the next process. Chinese utility model patent CN217707963U discloses a glove picking and stacking device, which sets a group of conveyor belts as multiple groups of belts set at intervals. The photoelectric switch detects the intervals between adjacent belts. The photoelectric switch will not detect the conveyor belt, and the gloves can be accurately detected when the gloves pass by. However, the inventor of this application found in the test process that due to the processing error of the belt, during the operation of each belt of a group of conveyor belts driven by a set of transmission mechanisms, the error between the belts will cause the belts to fluctuate during operation, and even deviate and creep. Creeping means that the sides of two adjacent belts overlap each other, which will seriously affect the normal transportation of the gloves and the detection of the gloves by the photoelectric switch.
