Pressure in the continuous automatic grader of the egg product egg device that falls
Technical field
The utility model relates to the egg device that falls in the continuous automatic grader of egg product, the egg device that falls of the pressure in the continuous automatic grader of particularly a kind of egg product.
Background technology
At present from a kind of egg product automatic washing of Taiwan import, continuous automatic grader, in automatic classification section, egg product 2 is driven by the defeated egg working chain 13 that has fin, lattice is failed egg continuously, evenly and is moved on the track 11 and 12 of two fixed supports, shown in Fig. 1 a, Fig. 1 b, Fig. 1 c.Egg product arrives the egg device that falls automatically after weighing device is weighed, have breach 121 on the fixed support track 12 at the egg device place that falls automatically, by the egg product movable support rod 4 in the egg device that falls automatically hold egg end 41 fill up the gap, shown in Fig. 1 a and Fig. 1 c.When egg product weight meets or exceeds setting weight at the corresponding levels, the transistor output conducting on the weighing device, PLC instruction electromagnet 31 dead electricity, under egg product deadweight effect, the egg end 41 that holds of egg product movable support rod rotates, and makes egg product fall into egg collection at the corresponding levels district 5, shown in Fig. 1 d.If egg product weight does not reach requirement at the corresponding levels, weighing device is output not, and the suction that another movable end 43 of egg product movable support rod is got electric electromagnet 31 holds, and egg product movable support rod 4 does not rotate, and egg product just passes through gap segments smoothly, arrives next stage and detects.The egg that falls of this egg device that falls is the deadweight that relies on egg product, and promptly after the electromagnet dead electricity, the egg product movable support rod is to rotate egg under the effect of egg product weight, and the egg speed that falls is slower; Electromagnet is inhaled journey little (having only 1-2mm) in addition, only depends on little balance weight 45 that the egg product movable support rod is slowly resetted after the egg that falls, and must reset in the electromagnet suction journey, and another movable end 43 of egg product movable support rod just can be held, and reset speed is also slower.Therefore; when defeated egg speed is very fast; the egg end that holds that the egg product movable support rod takes place through regular meeting does not reset to the fill up the gap place as yet fully; next egg product arrives; because this moment, electromagnet did not hold another movable end of egg product movable support rod as yet, even second egg product do not reach weight requirement at the corresponding levels, still can be under the deadweight effect; the egg end that holds of egg product movable support rod is rotated and the egg that falls once more, thereby cause the classification error.Obviously, defeated egg speed is fast more, and the classification error is many more.Production practices show, when defeated egg speed surpasses 7000-8000/hour, will produce the classification error.
The utility model content
The purpose of this utility model is to provide the egg device that falls of the pressure in the continuous automatic grader of a kind of egg product, and it can avoid the classification error, thereby accelerates the egg product transporting velocity greatly, improves the speed of the automatic series classification of egg product.
Technical solutions of the utility model are to constitute like this, it comprises a pair of fixed support track of being located on the automatic classification section of egg product, drive the defeated egg working chain of egg product along the track reach, at least one group of weighing device along track length segmentation setting, electromagnet control device by the output signal control work of weighing device, egg product movable support rod by electromagnet control device control rotation, wherein a track is provided with one section breach in the orientation of advancing of every group of weighing device, during the output of weighing device no signal, the egg end that holds of movable support rod is arranged in breach, it is characterized in that: be connected with between another movable end of movable support rod and the frame and be used to make the movable support rod back-moving spring of position that restores balance, described electromagnet control device comprises electromagnet and the motion bar that can be moved up and down by the electromagnet drive, the movable end of motion bar acts on the lever arm of movable support rod, when egg product during more than or equal to setting weight at the corresponding levels, the weighing device output signal makes electromagnet move downward egg by the egg end that holds that motion bar drives movable support rod.
The operation principle of the utility model technique scheme is described as follows: when egg product by weighing device at the corresponding levels claim weight during less than setting weight at the corresponding levels, the output of weighing device no signal, the holding that the egg end keeps supporting the equilbrium position of egg product of movable support rod and motionless; When egg product claims to such an extent that weight reaches at the corresponding levels and sets when requiring by weighing device at the corresponding levels, the weighing device output signal, electromagnet gets electric, drives motion bar and moves down, and the egg end that holds of movable support rod is rotated fast, and egg fast falls; Electromagnet dead electricity subsequently, another movable end of movable support rod drive the movable support rod fast rotation and reset under the effect of back-moving spring, meet next egg product.Egg all is fast with the speed that resets owing to fall, and has therefore avoided the classification error fully.Production practices show, even defeated egg speed reaches 15000/hour, also can avoid the classification error fully, that is to say by being provided with this and force the egg device, the speed of automatic series classification is doubled than original device about.
Therefore than prior art, the utlity model has following beneficial effect: can avoid the classification error, thereby accelerate the egg product transporting velocity greatly, improve the speed of the automatic series classification of egg product.
The utility model technique scheme has also been done following improvement:
For fear of because the excessive velocities of electromagnet when promoting movable support rod downwards and rotate by motion bar, and cause the egg end that holds of movable support rod to rotate excessively, influence next step the work that resets, above another movable end of movable support rod and the lever arm between the rotating fulcrum, be provided with in order to regulate the egg stopping means that falls of another movable end rotational travel of movable support rod.The described egg stopping means that falls is preferably the screw rod of adjustable-height position, so both can avoid the egg end that holds of movable support rod to rotate too wide-angle, and the egg end that holds of adjustable support bar rotates the angular dimension of stepping down again.
Equally, rotate excessively when the movable support rod rotation resets for fear of driving at spring, and make the egg end that holds of movable support rod surpass its equilbrium position, also be provided with above the lever arm between egg end and the rotating fulcrum in order to regulate the reset resetting and locating apparatus of equilbrium position of movable support rod holding of movable support rod.
In addition, when egg product claims to such an extent that weight reaches at the corresponding levels and sets when requiring by weighing device at the corresponding levels, in order further to help egg product to hurtle down, at the rotating fulcrum of movable support rod with hold the egg product side direction thrustor that also is fixed with on the lever arm between the egg end with the lever arm interlock, the push plate of described egg product side direction thrustor rests on another track outside relative with breach.Like this, when the movable support rod rotation is stepped down, drive egg product side direction thrustor synchronously and rotate, push egg product to the egg collection district from the track of equilbrium position fast to the breach direction.
