本實(shi)用新型(xing)涉及物(wu)流(liu)輸(shu)送領域，尤其涉及帶式輸(shu)送機。

背景技術：

遠距離帶式輸送機為了(le)滿(man)足(zu)重負荷啟動所(suo)需功(gong)率，設計功(gong)率相對較大且較多采用多機驅動，設備(bei)啟動后實(shi)際運行過程中(zhong)就(jiu)形成(cheng)了(le)大馬拉小車(che)的局面(mian)，使(shi)電能白白浪費。

技術實現要素：

本實用(yong)新(xin)型所要解決(jue)的技術問題是實現(xian)一種可以(yi)準確(que)可靠控制動力輸出(chu)，并能(neng)保證皮帶機的正常運(yun)轉。

為了實(shi)現上述(shu)(shu)目的，本實(shi)用新(xin)型采(cai)(cai)用的技術方案為：帶式(shi)輸送(song)機(ji)(ji)動(dong)力(li)驅(qu)動(dong)系統(tong)，帶式(shi)輸送(song)機(ji)(ji)至(zhi)少由(you)兩個(ge)(ge)電(dian)(dian)機(ji)(ji)驅(qu)動(dong)運(yun)轉，每個(ge)(ge)電(dian)(dian)機(ji)(ji)均(jun)由(you)獨立的皮(pi)帶機(ji)(ji)電(dian)(dian)源柜供電(dian)(dian)，系統(tong)設(she)有電(dian)(dian)流(liu)信(xin)號采(cai)(cai)集(ji)單元，所述(shu)(shu)電(dian)(dian)流(liu)信(xin)號采(cai)(cai)集(ji)單元采(cai)(cai)集(ji)每個(ge)(ge)電(dian)(dian)機(ji)(ji)的電(dian)(dian)流(liu)值信(xin)號，并將電(dian)(dian)流(liu)值信(xin)號實(shi)時輸送(song)至(zhi)PLC，所述(shu)(shu)PLC輸出控(kong)制信(xin)號至(zhi)每臺皮(pi)帶機(ji)(ji)電(dian)(dian)源柜。

所(suo)述PLC輸出電流(liu)值信(xin)號和(he)控(kong)制信(xin)號歷史信(xin)息至上位機(ji)。

所(suo)述(shu)帶(dai)式輸送機的運輸帶(dai)邊緣等間距設有(you)信號(hao)標(biao)記，所(suo)述(shu)帶(dai)式輸送機旁設有(you)讀取信號(hao)標(biao)記的測速單(dan)(dan)元，所(suo)述(shu)測速單(dan)(dan)元輸出皮(pi)帶(dai)運轉速度信號(hao)至PLC。

所述信號(hao)標記(ji)為(wei)金屬釘，所述信號(hao)標記(ji)位于皮帶的內圈。

本實用(yong)新型的優點在于(yu)在原有多機(ji)(ji)驅(qu)動大功率帶式輸送(song)機(ji)(ji)上(shang)(shang)進行改造，解決了大功率多臺驅(qu)動皮帶機(ji)(ji)“大馬(ma)拉小車”現象，在確保皮帶機(ji)(ji)運行的基礎(chu)上(shang)(shang)，合理的輸出驅(qu)動力(li)，可有效的降低大功率皮帶機(ji)(ji)能耗。

具體實施方式

帶(dai)式(shi)輸送機(ji)(ji)(ji)至(zhi)少由(you)兩個(ge)(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)驅動運(yun)轉(zhuan)，每個(ge)(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)均由(you)獨立(li)的(de)皮帶(dai)機(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源柜(ju)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian),皮帶(dai)機(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源柜(ju)由(you)PLC控制(zhi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)信(xin)號采(cai)集(ji)單元采(cai)集(ji)每個(ge)(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)值信(xin)號(電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)接線端電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu))，并將(jiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)值信(xin)號實時(shi)輸送至(zhi)PLC，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)的(de)功率輸出狀況(kuang)會由(you)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)的(de)輸入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)狀況(kuang)反映，通(tong)過電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)信(xin)號采(cai)集(ji)單元對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)實時(shi)的(de)監測，再(zai)根(gen)據(ju)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)變化設定值，及時(shi)退出或投入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)數量，來自動實現單、多機(ji)(ji)(ji)切(qie)換。

為(wei)了方便對(dui)系統進行監(jian)控(kong)，PLC輸(shu)出電(dian)流(liu)值(zhi)信號和控(kong)制信號歷史信息至上(shang)位機，上(shang)位機可以設置(zhi)在監(jian)控(kong)室(shi)(shi)，工作人員可以在監(jian)控(kong)室(shi)(shi)實時觀察帶式輸(shu)送機的工況，不需要現(xian)場(chang)查(cha)看就能監(jian)控(kong)設備(bei)運行狀況。

為了避免供(gong)電(dian)電(dian)壓波動而(er)發出(chu)錯誤的(de)關斷信(xin)(xin)號(hao)，帶式(shi)輸(shu)(shu)送機的(de)運輸(shu)(shu)帶邊(bian)緣等間距設(she)(she)有信(xin)(xin)號(hao)標(biao)記，信(xin)(xin)號(hao)標(biao)記沿著皮(pi)帶一側(ce)設(she)(she)置，用于讓測(ce)速單(dan)元(yuan)識別(bie)，測(ce)速單(dan)元(yuan)能夠實時的(de)獲取皮(pi)帶的(de)轉(zhuan)速并將轉(zhuan)速輸(shu)(shu)送至PLC，PLC可以(yi)利用速度信(xin)(xin)號(hao)作(zuo)為輔助判定信(xin)(xin)號(hao)，從而(er)投(tou)入合適的(de)電(dian)機數(shu)量(liang)，保證帶式(shi)輸(shu)(shu)送機正常運轉(zhuan)。

為了避免物料對信(xin)號(hao)標(biao)記遮擋(dang)干(gan)擾，信(xin)號(hao)標(biao)記位于皮(pi)帶的內圈，即正在運(yun)送物料的皮(pi)帶的下(xia)表面(mian)(mian)，信(xin)號(hao)標(biao)記可(ke)以為金(jin)屬釘(ding)，僅需(xu)與皮(pi)帶產生色(se)差既能讓測(ce)(ce)速(su)(su)單元(yuan)識別，測(ce)(ce)速(su)(su)單元(yuan)可(ke)以固定在皮(pi)帶的側(ce)面(mian)(mian)，傾斜讀取信(xin)號(hao)標(biao)記的運(yun)轉速(su)(su)度即可(ke)。

上面(mian)結合附圖對本(ben)發明進行(xing)了示例性描述，顯(xian)然本(ben)實(shi)(shi)用(yong)(yong)新型(xing)具體實(shi)(shi)現并不受(shou)上述方(fang)式的(de)(de)限制(zhi)，只要采用(yong)(yong)了本(ben)發明的(de)(de)方(fang)法(fa)構思和(he)技術方(fang)案進行(xing)的(de)(de)各種非實(shi)(shi)質性的(de)(de)改(gai)進，或未經改(gai)進將本(ben)發明的(de)(de)構思和(he)技術方(fang)案直接應用(yong)(yong)于(yu)其它場合的(de)(de)，均在本(ben)實(shi)(shi)用(yong)(yong)新型(xing)的(de)(de)保護范圍之(zhi)內。
