Description

Graded screening assembly line

Technical Field

The invention relates to a grading screening production line, in particular to the technical field of grading screening industries of vegetables, fruits and seafood.

Background

With the rapid development of national economy, the physical life of people is also greatly changed, and people pay more attention to the quality and quality of life. Therefore, at present, the essential products in life, such as agricultural products like vegetables, fruits, seafood and the like, need to be screened in a large quantity and high-quality agricultural products are selected for sale. At present, two working modes are generally adopted for screening vegetables, fruits and agricultural products:

firstly, adopt a large amount of manual works to carry out screening work in grades to hierarchical and check standard are through artificial judgement, and the standard is hardly quantized unified, simultaneously because the recruitment is more, it is great to produce the line, consequently leads to work efficiency low, and the cost of labor is high, and easily receives workman's subjective factor image and the error appears, thereby causes information erroneous judgement, reduces the precision of level screening etc..

And secondly, screening by adopting a mechanical hole or 360-degree imaging technology commonly used in the current market:

(1) if the mechanical hole is adopted for screening, the following defects exist: can only be applicable to single product, the product is cliied by the cavity easily, can only carry out the primary and secondary classification to roughly big or small, inconvenient adjustment, adjustment maintenance is troublesome.

(2) If a 360-degree imaging technology is adopted for screening, the 360-degree imaging technology is generally divided into two technologies, namely, one technology is adopted, namely, a lens and a 2-surface reflector are adopted; the disadvantages are: the brightness quality of the three pictures is inconsistent, the visual system is difficult to optimize and unify, the practicability is poor, and the three lenses are adopted; the disadvantages are: the cost is high, the service life of environmental water vapor, proper amount, dust and sundry images is prolonged, after the transparent protective device is adopted, the reflection and the definition of photos are difficult to guarantee for a long time, uninterrupted maintenance is needed, the maintenance cost is very high, and the device is not suitable for large-scale application and popularization.

The conventional classification screening is generally carried out through manual sorting by a single material channel, so that the problems of missing detection, low efficiency, easy information misjudgment and reduction of the precision of the classification screening exist, and the problems of high maintenance cost, unsuitability for large-scale application and popularization and the like exist when the mechanical hole or 360-degree imaging technology is adopted for screening. In the Chinese patent publication: CN 104624514A discloses a novel carrot machine vision choice grading production line, the above-mentioned technical scheme obtains the image of three side through mirror surface imaging and linear array camera, passes it to the computer, and the computer gives corresponding grade information through image processing, and then control the terminal high-speed pneumatic solenoid valve of third section conveyer, blows the carrot to the hierarchical mouth of different grades, has realized the choice of carrot full automatization and has graded. The technical scheme adopts a linear array camera, two mirrors with an included angle of 120 degrees are arranged on the lower side of a lamp strip on the upper side of the linear array camera, and a carrot real object image and two image images of the two mirrors are shot by the linear array camera under photoelectric induction, but the technical scheme adopts a lens and 2 reflectors; the method has the defects that the brightness quality of the three pictures is inconsistent, the visual system is difficult to optimize and unify, and the practicability is poor.

The conventional classification screening is generally carried out through manual sorting by a single material channel, so that the problems of missing detection, low efficiency, easy information misjudgment and reduction of the precision of the classification screening exist, and the problems of high maintenance cost, unsuitability for large-scale application and popularization and the like exist when the mechanical hole or 360-degree imaging technology is adopted for screening. In the Chinese patent publication: CN 108704859 a discloses a goods sorting and screening device, in the above technical scheme, the goods sorting and screening device adopts a main conveying device, a first auxiliary conveying device, a second auxiliary conveying device and a third auxiliary conveying device, and a movable goods sorting mechanism is added on the main conveying device, so that the device can move along the axis direction of a driven rotating shaft by controlling the operation of a propulsion motor, so as to realize goods sorting and screening, and can convey different goods through different conveying devices.
