Title:
REMOVAL AND DETECTION MECHANISM FOR DEFECTIVE PACKAGING ON VACUUM PACKAGING LINE AND OPERATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/024471
Kind Code:
A1
Abstract:
A removal and detection mechanism for defective packaging on a vacuum packaging line and an operation method thereof, wherein the removal mechanism comprises a control module, a conveyor belt (11), a packaging blocking mechanism (10), a positioning and centering mechanism (9) and a packaging retrieval mechanism (2). The packaging blocking mechanism (10) comprises a movable blocking plate (21), and the positioning and centering mechanism (9) comprises centering plates (14, 15). When packaging (12) is blocked by the blocking plate (21) at a blocking position, the centering plates (14, 15) clamp the object packaging and apply a preset clamping force. The packaging retrieval mechanism (2) comprises a torque measuring device, a stroke measuring device, and a grabbing device arranged above a conveying surface of the conveyor belt. A driving mechanism and a packaging-grabbing mechanism are arranged in the grabbing device, and the packaging-grabbing mechanism moves toward a grabbing surface (19) of the packaging (12). If the packaging-grabbing mechanism has not made contact with the grabbing surface within a preset time, the packaging retrieval mechanism (2) determines that the packaging (12) is defective packaging. After the packaging-grabbing mechanism has made contact with the grabbing surface (19), the packaging-grabbing mechanism applies pressure to the grabbing surface (19). If the grabbing surface (19) is deformed to an extent greater than a threshold value, the packaging retrieval mechanism (2) determines that the packaging (12) is defective packaging. The present device can detect and remove packaging without an effective vacuum seal from the conveyor belt.
