Abstract

The utility model relates to an automatic weight classifier which is suitable for the forging industry in particular to the weight sorting of the blank before the forging in the bearing industry. The utility model is controlled by the microcomputer. The feeding push plate delivers a piece of blank which is in the lowest bottom of the material storehouse to the upper side of the scalepan and the microcomputer reckons which grade the blank belongs to after obtaining the stable weight from the weighing sensor which is connected with the scalepan. The microcomputer instructs the grading shutter belonged to the grade open and at the same time the blank falls into the material box through the unclosed grading shutter after being turned down into the blanking sideway by the blanking turning plate. According to the program which grades the different weight blanks automatically and makes the blanks falling into different material boxes, the utility model can replace the existing artificial sorting by platform balance or balance.

Description

Weight antomatic sorting machine

This machine is mainly used in forging industry, the weight sorting of blank before particularly bearing industry forges.

At present, the weight low precision of blank usually can not satisfy the Forging Technology requirement before forging, so manufacturer will carry out artificial separation with blank with platform balance or balance before forging, still, efficient is low, the weight precision is low, the sorting class is few, labor strength is big.

The task of this invention is to design a kind of automatic weight classifier for overcoming above deficiency, replaces artificial separation.

The main technical schemes of this invention is: adopt microcomputer control.Treat that the blank of sorting puts into oblique feed bin slideway, microcomputer instruction cylinder makes the feeding push pedal the nethermost blank of feed bin, is pushed on the scale pan through marver, and the sensor under the scale pan is passed to microcomputer with weight signal.Microcomputer is told the class of this material, instructs the stepping valve that certain cylinder will these shelves to open then, and the cylinder of microcomputer instruction simultaneously makes blanking panel turnover plough under the blanking slideway to this blank, falls into hopper by the stepping valve that is opened.Repeat above action then, continue automatic sorting.

This machine respectively is made up of more than one stepping valve oblique feed bin slideway (being provided with width and lower end high degree of mechanical guiding mechanism), feeding push pedal, shelves flitch (being provided with position machinery guiding mechanism), marver (leading portion is provided with the updip ramp), the scale pan, blanking panel turnover (scale pan and blanking panel turnover are the comb shape chi structures, and scale pan surface is covered with damping material), microcomputer control cabinet, LOAD CELLS (bottom is provided with more than one vibration isolation material), cylinder, blanking slideway, blanking slideway both sides.The action of feeding push pedal, blanking panel turnover, stepping valve is finished by microcomputer control cabinet instruction air cylinder driven, also can with mechanical, electrical unite to drive finish.

Concrete structure

1,2 is described below in conjunction with the accompanying drawings: oblique feed bin (1) width and lower end adjustable height, shelves flitch (2) position is adjustable.Be the marver (3) that has the updip ramp under the feed bin discharging opening tiltedly, the marver back upper place is to be the scale pan (4) and blanking panel turnover (5) before feeding push pedal (11), the marver, the scale pan and blanking panel turnover are comb shape, and both broach intersect, the scale pan (4) connects with LOAD CELLS (14), LOAD CELLS is fixed on the frame (9) by at least a above vibration isolation material (13), and the cylinder air-channel system is installed in the frame.Branch latch device (8) is arranged in the blanking panel turnover front, and this device has blanking slideway (6), and the every side of slideway has at least more than one stepping valve (7).Microcomputer control cabinet (10) is installed on the frame (9).Oblique feed bin (1) raceway width-adjustable can adapt to the blank of different length.Tiltedly feed bin (1) lower end adjustable height and shelves flitch (2) position are adjustable, can adapt to the blank of different cross section, and can avoid blank to arch upward or can not blanking etc.The updip ramp of marver (3) can stop blank freely to roll forward, avoids a plurality of blanks to tumble in succession and delivered to the scale pan simultaneously from oblique feed bin (1).The comb shape toothing of the scale pan (4) and blanking panel turnover (5), the time that breaks away from the scale pan in the time of can making the blank blanking is short, and little to scale pan interference, improves separation velocity.Weighing sensor (14) is fixed on the frame (9) by vibration isolation material (13) transition, to the interference of sensor, has improved the speed and the precision of sorting when having alleviated extraneous vibration.Damping material (12) is applied on the scale pan (4) surface, and the impact that sensor when having reduced material loading (14) is subjected to has also improved the precision and the speed of sorting.

This utility model has the following advantages:

Simple and compact for structure, easy to adjust, versatility is good, antijamming capability is strong, separation velocity is fast, precision is high.
