Description

Self-adapting high speed sorting mechanism

Technical field

What the present invention relates to is a kind of self-adapting high speed sorting mechanism that is used for sorting fruit.

Background technology

China is fruit big producing country, and since 1993, the fruit total output just leaps to the No. 1 in the world, and of a great variety, and was wide in variety.But because detection and classification means are backward, most fruits is handled with regard to directly currency goes on the market, mixed level is mixed without sorting and is sold, and has had a strong impact on the market value of fruit.Though utilize manual work carry out the fruit quality detection and classification feasible, labour intensity is big, inefficiency, and because the influence of factors such as individual eyesight difference, color taste height, mood, fatigue and light power, the accuracy of classification is relatively poor.In recent years; Develop rapidly along with electronic technology, computer technology, image processing technique and mode identification technology; Utilize computer vision technique to carry out automatic grading of fruits and obtain broad research, all developed fruit machine vision automatic fraction collector both at home and abroad based on computer vision technique.And two key foundation parts of this series products are exactly fruit transport and fruit grading mechanism.For the fruit of guaranteeing to have class information can separate the classification line automatically and is brought in the different gathering-devices by rank; Fruit grading mechanism must accomplish the classification of fruit apace automatically under the control of fruit grader master control system; And in classification process; Also must reduce machinery and collsion damage, otherwise that whole sorting work will become will be meaningless to fruit as far as possible.

Existing fruit grading mechanism aims at large-scale fruit automatic sorting streamline and designs, but can not adapt to high-speed automated classification fully.

Summary of the invention

The objective of the invention is to overcome the deficiency of above-mentioned existence, and a kind of self-adapting high speed sorting mechanism that can realize the steady discharging of fruit is provided.

The objective of the invention is to accomplish: which comprises at least hierarchical chain through following technical scheme; This hierarchical chain is made up of drive sprocket, driven sprocket and classification chain; Wherein the classification chain is located on drive sprocket and the driven sprocket, on the classification chain, also is provided with pull-fork assembly and fruit cup assembly, and pull-fork assembly is arranged with fruit cup assembly space; Pull-fork assembly is installed on the classification chain; Described pull-fork assembly is made up of shift fork and torsion spring, and shift fork directly is connected with the classification chain, below shift fork, is provided with classification executing agency.

The shift fork of described pull-fork assembly is provided with one for first section and has a little the spacing of sharp mouth and a bearing pin installing hole, and interlude is provided with " Y " type boss, and back segment is provided with a slope; Described shift fork is positioned on the dedicated aluminium alloy guide rail with the classification chain that links to each other.

Described classification chain outer plate is provided with two kinds and has strong market potential and a kind of gear pin, wherein have strong market potential and the gear pin is installed with pull-fork assembly through a kind of, and another kind is had strong market potential the fruit cup assembly is installed.

The invention belongs to a kind of improvement to prior art, it compared with prior art has the following advantages:

1 the present invention requires low to electromagnet action control in the fruit grading process; And the electromagnet stroke is short; the very little angle of rocking arm swing just can realize automatic classification (angle is between 15 degree-30 degree); help prolonging electromagnet service life, the while can be realized the high speed classification, raising fruit grading equipment productivity.

2 the present invention rocking arm in the fruit grading process owing to the effect of torsion spring, can adapt to circulation next time automatically after classification.

3 the present invention are simple in structure, and it is convenient to change.

The specific embodiment

Label in the accompanying drawing is: 1, drive sprocket; 2, classification chain; 3, fruit cup assembly; 4, pull-fork assembly; 5, dedicated aluminium alloy guide rail; 6, driven sprocket; 7, shift fork; 8, torsion spring; 9, " Y " type boss; 10, the fruit cup connects bearing pin; 11, bearing pin installing hole; 12, have a little the spacing of sharp mouth; 13, slope; 14, chain outer plate; 15, gear pin; 16, having strong market potential of pull-fork assembly is installed; 17, having strong market potential of fruit cup assembly is installed.

To combine accompanying drawing that the present invention is done detailed introduction below:

As shown in Figure 1, the present invention is by classification chain 2, and pull-fork assembly 4 is formed with fruit cup assembly 3 three parts.

Like Fig. 1, Fig. 2, shown in Figure 7, a kind of self-adapting high speed sorting mechanism, it comprises hierarchical chain; This hierarchical chain comprises drive sprocket 1, driven sprocket 6 and classification chain 2, and wherein classification chain 2 is located on drive sprocket 1 and the driven sprocket 6, on classification chain 2, is provided with pull-fork assembly 4 and fruit cup assembly 3; And pull-fork assembly 4 is arranged with fruit cup assembly 3 spaces; Pull-fork assembly 4) comprise shift fork 7, and shift fork 7 is installed on the classification chain 2 and can swings, described pull-fork assembly 4 is made up of shift fork 7 and torsion spring 8; Shift fork 7 directly is connected with classification chain 2; And fix with jump ring, below shift fork 7, being provided with classification executing agency, 7 of shift forks are along with classification chain 2 moves on dedicated aluminium alloy guide rail 5.

During work,, the fruit in the pallet is sent into corresponding sorting outlet, send by serial ports of computers according to previous Computer Processing result then by motor-driven classification chain 2, the result signal of single-chip microcomputer receiving computer, and call sorting control subprogram.After program is finished, transmit control signal, make the electromagnet mechanism action to corresponding sorting switch; Stir corresponding shift fork 7 to 15 degree-30 degree, feasible fruit cup unstability, and under the gravity effect; Fruit cup glides, thereby causes that fruit drops to corresponding outlet in the fruit cup, realizes sorting.After sorting finished, electromagnet mechanism recovered off-position, and shift fork recovers reset condition under torsion spring 8 effects, wait for circulation next time.

Like Fig. 3, shown in Figure 4, the shift fork of pull-fork assembly 4 is provided with the spacing 12 and bearing pin installing holes 11 that have a little sharp mouth for 7 first sections, have a little spacing 12 of sharp mouth can avoid shift fork can not self-return and return excessive; Interlude has " Y " type boss 9, is used for shelving fruit cup assembly 3, and back segment has a slope 13, can be beneficial to the electromagnet action.

Like Fig. 5, shown in Figure 6, classification chain 2 outer plates 14 be provided with two kinds have strong market potential with a kind of gear pin 15, wherein through a kind of have strong market potential 16 and gear pin 15 pull-fork assembly 4 is installed, through another kind have strong market potential 17 be installed with the fruit cup assembly 3.
