Abstract
The utility model belongs to the technical field of automatic detection and relates to a machine vision-based device for automatically detecting surface seasoning bag loss of a container. The device comprises a computer, two video cameras, light sources, an image acquisition card, an in-position sensor, a programmable logic controller (PLC), a servo motor, a screw rod guide rail and an encoder, wherein the in-position sensor is used for sensing the working beat of a package line and outputs the working beat to the computer; the screw rod guide rail is driven by the servo motor; the two video cameras are fixed to the two ends of a guide rail of the screw rod guide rail respectively; a light source is fixed under or right above the two video cameras respectively; the encoder is fixed at the tail end of a screw rod of the screw rod guide rail; and the signal output end of the encoder is connected with the PLC. The interference of objective factors in a manual visual evaluation method is eliminated completely, the presence and quantity completeness of a seasoning bag can be detected rapidly, objectively and correctly and the detection accuracy and efficiency of product quality are enhanced greatly.
Description
Technical field
The utility model belongs to the Automatic Measurement Technique field, particularly the device that whether lacks about material package in the detection receptacle bread dress.
Technical background
Along with the aggravation of global economic integration trend, the food and medicine industry is also more and more higher to the requirement of product design, forces the company of relevant industries and enterprise to drop into more manpower financial capacity on the quality control surveillance of product.In the instant noodles packaging process, the material package integraty of instant noodles is importances weighing product design.And the material package disappearance appears in instant noodles product, and not only can cause client's complaint and claim after coming into the market, and brings unpredicted fame and economic loss to manufacturer, directly influences the market image of manufacturer, has also damaged client's interests simultaneously.
Carry out at present the vessel faces material package detection mainly be to use manual detection, in the automatic operational process of vessel faces Production and Packaging line, dissimilar material packages, automatically added and be placed on the face cake as powder bag, green vegetable bun and sauce bag etc., station place before packing, whether there is material package disappearance problem by operative employee's visual inspection, and carries out the interpolation or the rejecting of corresponding material package.The manual detection method is convenient, directly perceived, the accuracy height, but it is bigger influenced by subjective factor, and workman's working strength is big, works long hours easily to cause visual fatigue, misjudgment occurs, influences the quality testing of product; And when the baling line excessive velocities, the operative employee can't finish detection substantially.
The utility model content
In view of the above problems, the purpose of this utility model provides a kind of vessel faces material package disappearance automatic checkout equipment based on machine vision that can adapt to the Fast Packet wiring.The utility model is achieved through the following technical solutions:
A kind of vessel faces material package disappearance automatic checkout equipment based on machine vision, comprise computing machine, pick up camera, light source, image pick-up card, to level sensor and PLC programmable controller, described pick up camera links to each other with computing machine by image pick-up card, described to level sensor, be used for the work tempo of perception baling line, its output is admitted to computing machine, described detecting device also comprises servomotor, lead screw guide rails and coder by driven by servomotor, described pick up camera has two, be separately fixed at the guide rail two ends of lead screw guide rails, under two pick up cameras or directly over each fixes a light source, described coder is fixed on the leading screw end of lead screw guide rails, and the code device signal mouth links to each other with the PLC coding controller.
As preferred implementation, described light source is the dome light source; Described pick up camera is the colour plane array camera.
Vessel faces material package of the present utility model lacks automatic checkout equipment, and by images acquired, the existence of detection material package is in time reported to the police or rejecting for the product of disappearance material package, thus the quality of the assurance packing of product.This device is applied on the similar products baling line, has overcome the interference of subjective factor in artificial visually examine's method fully, and energy is quick, objective, existence and the quantity integraty to material package detects accuracy of detection of improving the quality of products greatly and efficient exactly.
Description of drawings
Fig. 1: the utility model hardware system outward appearance is formed scheme drawing;
Fig. 2: the utility model software detection analytic product diagram of circuit.
The accompanying drawing marking explanation:
1 computing machine; 2 lead screw guide rails; 3 colour plane array cameras; 4 lighting sources; 5 coders; 6 servomotors, 7 to level sensor.
The specific embodiment
Referring to Fig. 1, vessel faces material package disappearance automatic checkout equipment based on machine vision of the present utility model, mainly comprise computing machine 1, lead screw guide rails 2, colour plane array camera 3, lighting source 4, coder 5, servomotor 6 and to level sensor 7, the Color Image Acquisition system is made of face battle array colourful CCD video camera 3 and the image pick-up card that is installed in the computing machine, lighting source 4 adopts shadowless lamp, as the dome light source.Computer-internal is equipped with image acquisition Control Software and analyzing and detecting software.
Present embodiment is applicable to (by transforming the situation that also can adapt to below 10) on the baling line that detects 10 vessel faces simultaneously, is installed in baling line code-disc place to level sensor and detects the baling line movement rhythm, and the signal of its output is admitted to computing machine; It is employing face battle array colourful CCD video cameras that light source 4 adopts dome light source, pick up camera 3, each pick up camera is installed in directly over the dome lamp (under also can being) and constitutes one and is installed on the guide rail, and the distance between two pick up camera centers is 5.5 face cake center-to-center distances; Lead screw guide rails is installed in directly over the baling line by support; Coder is installed in the leading screw end, and the rotation of coder axle and leading screw rotation keep synchronously, and the code device signal mouth links to each other with PLC, can control ccd video camera by the PLC programmable controller and trigger the moment of taking pictures; Pick up camera, is all finished by power supply in the rack by cable to the power supply of level sensor, PLC programmable controller and motor and actuator thereof etc. light source.
The method that realizes: be installed in baling line main shaft place to level sensor, the perception vessel faces enters the detection station; Directly over detecting station lead screw guide rails is installed by support, pick up camera 3 and lighting source 4 are made whole case and are fixed on the guide rail, can be along guide rail movement; After vessel faces entered and detects station, computing machine perceived the level sensor energizing signal, and starter motor drives pick up camera along guide rail movement; PLC perceptual audio coder signal, during over against the vessel faces center, pick up camera is taken the vessel faces image under determining pick up camera; Image pick-up card is gathered the instant noodles image in the computing machine, analysis image, and promptly the difference aspect physical propertys such as color, size between material package and the face cake is judged the existence of material package; If the material package disappearance is then to report to the police, perhaps rejected.
