The specific embodiment:
Examine under a microscope the architectural feature of sleeve, find the sleeve piece as well as inner width obviously greater than outside (see figure 3), and high conformity.According to this characteristic Design sleeve orientation collating unit (Fig. 2).This device mainly comprises directed arrangement axle 1, rotating disk 13, lifting disk 14, baffle plate 5, gear wheel 15 and push-off pin 10.Core part is 7 pairs of arrangement axles 1 that are parallel to each other, structure such as Fig. 3 of arrangement axle leading section.Arrangement axle front end inside has one can be called arrangement tongue 22 around bearing pin 19 rotating sheet metals, and it can eject under the effect of spring 21.When sliding sleeve 3 under spring 2 effect when arrangement axle front end slides, can be pressed into the arrangement tongue in the arrangement axle.
Establish 20 stations on the rotating disk 13, hold 20 pairs of sleeves, the station on the rotating disk is divided into four zones: the A district, from feed bin, wait for the sleeve of arrangement; The B district, the sleeve of putting in order; The C district is through the sleeve of arrangement; The D district, idle station.Rotating disk is driven by motor gear 8 and disk gear 9 by motor 6.Sleeve 4 before the directed arrangement falls into the sleeve locating hole 26 that rotating disk is positioned at the A district from the feed bin of existing assembly machine.Baffle plate 5 belows are arrangement stations, and after the arrangement, the sleeve after push-off pin 10 is put orientation in order is released rotating disk and fallen into feeding channel.All embed a rubber ring 28 in all sleeve locating hole 26 on the rotating disk, the effect of this rubber ring is:
(1) prevents that sleeve is organized axle before falling into seam at the cutting edge of arrangement tongue and is being with and turns round;
(2) prevent sleeve landing from rotating disk.Locate by alignment pin 11 between rotating disk and the lifting disk.
Lifting disk was in the nextly when working cycles began, and an end connects lifting disk 14, the other end is connected and installed in the extension spring 32 of the small column 31 on the gear wheel 15 and the initial position that backing pin 30 is determined lifting disks.Arrangement axle 1 is concentric with the sleeve 4 that is organized, and when the electromagnet coil that embeds rotating disk inside inserts electric current, attracts lifting disk to rise, and lifting disk drives the arrangement axle and rises, and the arrangement axle inserts corresponding sleeve respectively.When the arrangement axle inserted sleeve, sliding sleeve 3 was pushed downwards, and axle outer spring 2 is compressed.The baffle plate 5 on rotating disk top prevents that sleeve is organized axle and ejects rotating disk.When the designated depth of arrangement axle insertion sleeve, rotating disk revolution.Because arrangement shaft gear and gear wheel mesh all the time, the arrangement axle when being driven revolution by rotating disk also around self axis rotation.In the rotation process of the relative sleeve of arrangement axle, because the effect of axle inner spring 21, in case run into the seam of sleeve inner, the cutting edge of arrangement tongue just falls into seam, drives sleeve and the together revolution of arrangement axle, arrives the direction of stipulating and stops operating.The electromagnet outage, lifting disk is fallen, and drives the arrangement axle and extracts out in sleeve.Sliding sleeve 3 slides to the arrangement shaft end under the effect of axle outer spring, will put tongue in order and be pressed in the arrangement axle, stops sleeve to be organized axle simultaneously and takes out of.Lifting disk reduce to the next after, reversed turning is to initial position.The present embodiment device has 7 pairs of arrangement axles, can put 7 pairs of sleeves simultaneously in order.Work tempo is 6 seconds, and 70 pairs of sleeves are put in 10 circulations of per minute in order, has satisfied the requirement of automation assembling.
Accurate for guaranteeing the arrangement action, must guarantee:
(1) when falling into the locating hole of each station, the feed bin of assembly machine can not pass the rotating disk landing when sleeve;
(2) sleeve was not with the revolution of arrangement axle before the cutting edge of arrangement tongue 22 fell into seam;
(3) fall into seam in case put the cutting edge of tongue in order, sleeve is just with the revolution of arrangement axle;
(4) the arrangement axle stops in the orientation of determining, sleeve promptly stops in certain orientation, and the arrangement action is finished.
Aforementioned (1), (2) are to realize by all embedding a rubber ring 28 with damping action in the sleeve locating holes 26 all on rotating disk 13.(3) is by both can exposing, and arrangement tongue that again can indentation arrangement axle is realized.The cutting edge of arrangement tongue has identical cross sectional shape with the sleeve inner seam.Under the effect of spring 21, in a single day the arrangement tongue runs into seam, and its cutting edge just falls into seam, drives sleeve with the revolution of arrangement axle.(4) is the integer speed ratio by gear wheel 15 and arrangement shaft gear 18 and remains engagement and guarantee.Big or small gear ratio is 10: 1 in the present embodiment device, establishes 20 stations on the rotating disk, holds 20 pairs of sleeves.When rotating disk turns over 2 stations, to put axle in order and then turn round 1, i.e. in every 1/10th weeks of revolution of rotating disk, the arrangement axle returns and circles.Adjust gear wheel 15 and the initial position of putting shaft gear 18 in order during installation, the arrangement axle is aimed at the station on the rotating disk, then gear wheel 15 and axle 16 are fixed.
The arrangement shaft diameter is less in this device, and rigidity is poor, so needs in the course of work to guarantee that the arrangement axle is not subjected to bending load.Rotating disk drives lifting disk 14 revolutions by alignment pin 11, and the diameter of alignment pin 11 is greater than the arrangement axle.When the lifting disk rising, the alignment pin on the lifting disk inserted the dowel hole on the rotating disk before the arrangement axle inserts sleeve.When lifting disk descends, the alignment pin on the lifting disk is the dowel hole extraction from the rotating disk after the arrangement axle is extracted sleeve out.Alignment pin extract out the back lifting disk by extension spring 32 driver inversion to initial position.
Rotating disk top when plate 5 and the function that is enclosed within axle outer spring 2 and sliding sleeve 3 on the arrangement axle be respectively: when the arrangement axle inserts sleeve, sleeve is not ejected rotating disk; When extracting sleeve out, the arrangement axle sleeve is not taken out of rotating disk.Plate washer 5 is an inclined-plane with the one side that sleeve 4 begins to contact, and when rotating disk drove the sleeve just fallen into A district sleeve locating hole 26 and turns round, the sleeve that the inclined-plane will not fall into as yet fully owing to stopping of rubber ring made its upper surface concordant with the rotating disk lower surface to pressing down.
Accurately consistent for the work tempo that guarantees the sleeve orientation collating unit with the work tempo of assembly machine, realize with the speed ratio of disk gear 9 by adjusting motor speed and motor gear 8 in the usual way.
The sleeve of putting in order need fall into the holding fix of feeding channel accurately.When the sleeve of putting in order goes to holding fix top, push-off pin 10 is released sleeve, falls into the holding fix of feeding channel.
In order to satisfy the high-speed of assembly machine, device adopts the method for parallel arrangement, and present embodiment has 7 pairs of arrangement axles, can put 7 pairs of sleeves simultaneously in order.70 pairs of sleeves of per minute arrangement have satisfied the requirement of automation assembling.And adopt optics method for sorting, single arrangement then can not satisfy the high-speed of assembly machine, and parallel arrangement then needs the identical equipment of many covers, and cost certainly will obviously increase.
The sleeve dimensions of this device arrangement is external diameter 6.35mm, internal diameter 4.45mm, length 8.50mm.This technology is applicable to the chain of all specifications.
