Description

一种低噪音、防震花螺丝自动送料器及控制过程
技术领域
本发明涉及螺丝组装设备技术领域，尤其涉及一种自动螺丝送料设备。
背景技术
组合式螺丝在很多行业都会使用到，其结构通过由分立的两部分组成，在出厂时一般由厂家将其组装好，在螺丝搓牙或组装过程需要用送料装置将螺丝送入生产设备中。现有技术中，通常采用由旋振器51、进料振动盘52、盘内旋涡53、进料槽54、组成的振盘式送料器。振盘式送料器存在的缺陷在于：由于是振动工作，机器运转时产品与产品之间、产品与振动盘52之间产生比较强烈的碰撞，不仅会严重碰花产品的表面、碰坏牙，严重影响产品的外观与使用功能，而且会产生极大的噪音，如1000平方米的厂房只要放上4台以上，声音就会覆盖全个车间；另外能耗大,每小时耗电1度。
发明内容
（一）要解决的技术问题
本发明要解决的技术问题是提供一种生产效率高、不会损坏产品、几乎无噪声、耗能低的螺丝自动送器。
（二）技术方案
为解决上述技术问题，本发明采用如下技术方案：一种低噪音、防震花螺丝自动送料器，其特征在于：包括左墙板1、右墙板2、后墙板3及电气系统6，后墙板3安装在左墙板1与右墙板2之间，左墙板1、右墙板2及后墙板3构成该自动送料器的料斗；在左墙板1与右墙板2之间安装有至少一道摆轨15及数量与摆轨相同的导轨17，摆轨15设在后面与料斗对接，导轨17设在前面，摆轨15与导轨17对接，从摆轨15到导轨17呈摆轨后端高、导轨前端低的倾斜结构；摆轨15安装在摆轨轴24上，摆轨轴24两端分别固定在左墙板1和右墙板2上，每一摆轨下端安装有一摆轨动力轴承14，每一摆轨动力轴承对接一凸轮13，所有凸轮同轴安装在一花键轴12上，花键轴12连接一从动链轮11，从动链轮12通过链条10连接主动链轮9，主动链轮9连接调速电机8，调速电机8连接电气系统6；导轨17安装在导轨固定块16上，导轨固定块16安装在左墙板1和右墙板2之间；在导轨17上方安装有位置可移动的工件逐一放料闸阀系统，其包括分别安装在左墙板1和右墙板2上的左限位板18和右限位板19，在左限位板18和右限位板19之间安装有前后两根可左右移动的限位杆，后限位杆20上安装有后限位趾21，前限位杆22上安装有前限位趾23，后限位趾21及前限位趾23的底端与导轨17表面齐平并悬于导轨上方，前限位趾和后限位趾的宽度小于相邻导轨之间的间隙；前限位杆和后限位杆分别连接有推动其左右移动的驱动装置。
优选地，在料斗的前端设有前助入斜块4，在料斗的后端设有后助入斜块5，前助入斜块4和后助入斜块将5料斗底部构成倾斜结构。
优选地，所述摆轨15呈扇形结构，其后端宽、前端窄，摆轨前端为凸弧形结构，导轨17后端则为与摆轨15前端相匹配的凹弧形结构。
优选地，在导轨17后端处安装有导轨固定板27，导轨固定板27上固定有用于给导轨加强定位的导轨固定块28。
优选地，链条10由链条7罩盖住。
优选地，摆轨15的尾端上边缘部具有向上弯曲凸起的钩状部，这种结构使工件不会从摆轨15尾部落回，尾端的后边缘为弧形结构。
优选地，所述驱动装置为气缸、油缸或马达。
优选地，所述凸轮13的结构均相同，所有凸轮均相互平行，相邻凸轮错开角度设置在花键轴12，就是说所有凸轮不是对称设置，这样一方面可以使电机保持均匀地输出动力，另一方面可以使摆轨做不同步的起伏运动，即有的摆往下运动，而有的摆轨则向上运动，可调节工件堆放的位置，使工件更为均匀地进入摆轨中。
所述自动送料器的控制过程：调速电机8、主动链轮9、链条10、从动链轮11、花键轴12作等速运转，带动凸轮13转动，凸轮13带动摆轨动力轴承14转动，摆轨动力轴承14沿凸轮13外径滚动，摆轨15随之以摆轨轴为中心轴24作上下摆动，料斗内的工件有规律地落入摆轨15的中间排列槽内，当摆轨到达上限点位置时，工件在自身重力作用下沿槽面下滑进入导轨17的槽内，由于后限位趾21的阻挡，工件有序排列在导轨17的槽内上半部份；通过气缸25控制后限位杆20向外移动、后限位趾21松开时，导轨17的每个料槽都会放行一个工件至前限位趾23，此时，后限位杆20复位，通过气缸26控制前限位杆22向外移动，前限位趾23松开露出通道将工件逐一放出。

具体实施方式
实施例1，参照图2、图3和图4，所述低噪音、防震花螺丝自动送料器，其为八头自动送料器，包括左墙板1、右墙板2、后墙板3及电气系统6，后墙板3安装在左墙板1与右墙板2之间，左墙板1、右墙板2及后墙板3构成该自动送料器的料斗；在左墙板1与右墙板2之间安装有八道（当然也可以是一道或者多道）摆轨15及八道导轨17，摆轨15设在后面与料斗对接，导轨17设在前面，摆轨15与导轨17对接，从摆轨15到导轨17呈摆轨15后端高、导轨17前端低的倾斜结构；摆轨15安装在摆轨轴24上，摆轨轴24两端分别固定在左墙板1和右墙板2上，每一摆轨15下端安装有一摆轨动力轴承14，每一摆轨动力轴承14对接一凸轮13，所有凸轮13同轴安装在一花键轴12上，花键轴12连接一从动链轮11，从动链轮11通过链条10连接主动链轮9，主动链轮9连接调速电机8，调速电机8连接电气系统6；导轨17安装在导轨固定架16上，导轨固定架16安装在左墙板1和右墙板2之间；在导轨17上方安装有位置可移动的工件逐一放料闸，其包括分别安装在左墙板1和右墙板2上的左限位板18和右限位板19，在左限位板18和右限位板19之间安装有前后两根可左右移动的限位杆，后限位杆20上安装有后限位趾21，前限位杆22上安装有前限位趾23，后限位趾21及前限位趾23的底端与导轨17表面齐平并悬于导轨17上方，前限位趾23和后限位趾21的宽度小于相邻导轨17之间的间隙；前限位杆22和后限位杆20分别连接有推动其左右移动的气缸25、26，当然也可以是油缸或者电机。
在料斗的前端设有前助入斜块4，在料斗的后端设有后助入斜块5，前助入斜块4和后助入斜块5将料斗底部构成倾斜结构。
摆轨15呈扇形结构，其后端宽、前端窄，摆轨15前端为凸弧形结构，导轨17后端则为与摆轨16前端相匹配的凹弧形结构。
在导轨17后端处安装有导轨固定板27，导轨固定板27上固定有用于给导轨加强定位的导轨固定块28。
链条10由链条罩7盖住。
摆轨15的尾端上边缘部具有向上弯曲凸起的钩状部，这种结构使工件不会从摆轨尾部落回，尾端的后边缘为弧形结构。
凸轮13的结构均相同，所有凸轮均相互平行，相邻凸轮错开角度设置在花键轴12上，就是说所有凸轮不是对称设置，这样一方面可以使电机保持均匀地输出动力，另一方面可以使摆轨做不同步的起伏运动，即有的摆往下运动，而有的摆轨则向上运动，可调节工件堆放的位置，使工件更为均匀地进入摆轨中。
控制过程说明：工件装入料斗后，由于前助入斜块4和后助入斜块5的作用自动滚落到料斗的最底处，自动做好排列前准备。启动设备，调速电机8、主动链轮9、链条10、从动链轮11、花键轴12作等速运转，带动凸轮13转动，凸轮13带动摆轨动力轴承14转动，摆轨动力轴承14在整个动作过程中，跟凸轮13完全做滚动运动，减小了磨擦力和工作噪音，且凸轮13和摆轨动力轴承14之间没有间隙，所以几乎没有噪音；凸轮13作旋转运动，摆轨动力轴承14沿凸轮13外径滚动，摆轨15随之作以摆轨轴24为中心轴的上下摆动，而料斗内的工件则有规律地落入摆轨15的中间排列槽内，当摆轨15到达上限点位置时，工件在自身重力作用下沿槽面下滑，进入导轨17的槽内，由于后限位趾21的阻挡，工件有序排列在导轨17的槽内上半部份；通过气缸25控制后限位杆20在气缸27推动下向外移动、后限位趾21松开时，导轨17的每个料槽都会放行一个工件至前限位趾23，此时，后限位杆20复位，前限位杆22在另一气缸26的控制下向外移动，前限位趾23松开露出通道，逐一将加工件放入自动化的组装加工设备的加工工位；由于气缸25、26是连接组装设备（即主机）的控制系统的，因此气缸25、26的动作可通过主机的控制系统调节，这样即是调节放料的时间。
实施例2，参照图5，与实施例1所不同的地方在于，其为一头自动送料器，设置有一道摆轨15和一道导轨17，凸轮13则对称设置有两个，其中一个与摆轨动力轴承14对接，另一个悬空在外，起到平衡调速电机8所承受的力的作用。
以上已将本发明做一详细说明，以上所述，仅为本发明之较佳实施例而已，并不限制本发明实施范围，即凡依本申请范围所作均等变化与修饰，皆应仍属本发明涵盖范围内。
工业实用性
本发明通过采用独创设计的摆轨、导轨、凸轮等部件相互配合工作，设备噪音低、防震花、产品品质好、全自动操作、高效节能，本发明工作时耗能约为每小时0.2度电，比现有振盘式送料器节约能源5倍左右，特别是低噪音方面确是一大突破，可以说几乎不会产生噪音，绿色环保，改善了工作环境，也减少了劳动力，极大地提高了生产效益和产品的品质，降低了加工成本。

    2．根据权利要求1所述的低噪音、防震花螺丝自动送料器，其特征在于：在料斗的前端设有前助入斜块(4)，在料斗的后端设有后助入斜块(5)，前助入斜块(4)和后助入斜块(5)将料斗底部构成倾斜结构。
    3．根据权利要求1所述的低噪音、防震花螺丝自动送料器，其特征在于：所述摆轨(15)呈扇形结构，其后端宽、前端窄，摆轨前端为凸弧形结构，导轨(17)后端则为与摆轨(15)前端相匹配的凹弧形结构；摆轨呈方形、圆形等形状均可。
    4．根据权利要求1所述的低噪音、防震花螺丝自动送料器，其特征在于：在导轨(17)后端处安装有导轨固定板(27)，导轨固定板(27)上固定有用于给导轨加强定位的导轨固定块(28)。
    5．根据权利要求1所述的低噪音、防震花螺丝自动送料器，其特征在于：链条或皮带(10)由链条罩(7)盖住。
    6．根据权利要求1所述的低噪音、防震花螺丝自动送料器，其特征在于：摆轨(15)的尾端上边缘部具有向上弯曲凸起的钩状部，尾端的后边缘为弧形结构。
    7．根据权利要求1所述的低噪音、防震花螺丝自动送料器，其特征在于：所述驱动装置为气缸、油缸或马达。
    8．根据权利要求1所述的低噪音、防震花螺丝自动送料器，其特征在于：所述凸轮(13)的结构均相同，所有凸轮均相互平行，相邻凸轮错开角度设置在花键轴(12)上。
    9．权利要求１所述的低噪音、防震花螺丝自动送料器，其特征在于：若左墙板(１)与右墙板(２)之间只安装一道摆轨(15)，花键轴(12)上除了安装一个凸轮以外，还在花键轴(12)上安装一个平衡力凸轮。
    10．权利要求1所述自动送料器的控制过程，其特征在于：调速电机(8)、主动链轮(9)、链条(10)、从动链轮(11)、花键轴(12)作等速运转，带动凸轮(13)转动，凸轮(13)带动摆轨动力轴承(14)转动，摆轨动力轴承(14)沿凸轮(13)外径滚动，摆轨(15)随之以摆轨轴为中心轴(24)作上下摆动，料斗内的工件有规律地落入摆轨(15)的中间排列槽内，当摆轨到达上限点位置时，工件在自身重力作用下沿槽面下滑进入导轨(17)的槽内，由于后限位趾(21)的阻挡，工件有序排列在导轨(17)的槽内上半部份；通过气缸(25)控制后限位杆(20)向外移动、后限位趾(21)松开时，导轨(17)的每个料槽都会放行一个工件至前限位趾(23)，此时，后限位杆(20)复位，通过气缸(26)控制前限位杆(22)向外移动，前限位趾(23)松开露出通道将工件逐一放出。
