19、續(xù)的稱重的原理1-1. Principle of continuous weighing 給料機的輸送量由下列方程式表示：The feeding amount of the feeding machine is expressed by the following equation: Q：輸送量 (重量范圍 0t1) (kg)Q：Feeding amount (the weight ranges from 0t1) (kg)q：瞬時輸送量 (kg/min)q: Instantaneous feeding amount (kg/min)W：物料的單位長度重量 (kg/m) (載荷密度)W: Ma

20、terials weight in a unit length (kg/m) (load density)V：皮帶速率 (m/min)V: Belt speed (m/min)設輸送帶的運行長度為l，輸送帶的速度為v，輸送帶運行時間為t, 那么：It is set that the running length of the conveyer belt is to be 1 and the running time of the conveyer belt is t, then: l=vt因此在輸送帶運行了 t1時間后，輸送帶的運行長度為l1=vt1，那么，輸送量可用下列方程式表示：There

21、fore, after the conveyer belt runs for t1, the running length of the conveyer belt is l1=vt1 and the feeding amount can be expressed by the following equation:上式表明，定量給料機的輸送量為A，B，C三點所包圍的面積。如圖Fig.1 1所示。The above equation indicates that the feeding amount of the batching feeding machine is the encircle

22、d area of Point A, Point B and Point C, shown as Fig.1 1. W單位長度重量W = f(1)CLFig.1 - 1AB W = f (1) : 在任選的單位運行長度 l 上的載荷密度W = f (1): Load density on the random unit running length 1Wdl : 在微小運行距離(dl)上的輸送量Wdl: Feeding amount on the minimum running distance (d1)上述表明：要獲得輸送量，需通過稱量傳感器檢測到物料的單位長度的瞬時重量信號，同時速度傳感器

23、檢測到速度脈沖信號。通過控制儀表將重量信號與速度信號進行乘積運算，從而求得輸送量。The above indicates: in order to attain the feeding amount, it is necessary to utilize the weighing transducer to inspect the instantaneous weight signals of the material in a unit length and at the same time the speed detector to inspect the speed pulse sign

24、als. The control instrument shall be applied to carry on product calculation toward the weight signals and speed signals so as to get the feeding amount. 1- 2. 稱量和控制系統(tǒng)1-2 Weighing and Controlling System 如 Fig.1- 2的流程圖所示，本設備主要分為四大單元：稱重單元，皮帶測速單元，積算控制儀表單元和驅(qū)動單元。Shown as the flow chart of Fig.1-2, this e

25、quipment is mainly divided into four major units: a weighing unit, a belt speed detector unit, an integrating control instrument unit and a driving unit. 稱重單元，皮帶測速單元，驅(qū)動單元作為輸送機的部件安裝在輸送機上。The weighing unit, belt speed detector unit and the driving unit are installed on the feeding machine as the feedi

26、ng machines components. 稱重單元主要由計量托輥和兩個稱重傳感器組成。稱重傳感器安裝在高精度的平臺上，兩個傳感器測量出輸送帶上物料的單位長度重量，然后將重量信號傳送至積算控制儀表。The weighing unit is mainly composed of a measuring support roller and two weighing transducers. The weighing transducers are installed on the high-precision platform so as to measure the materials w

27、eight in a unit length on the conveyer belt and then the weight signals are transmitted to the integrating control instrument. 皮帶測速單元采用編碼器安裝在驅(qū)動滾筒軸端，通過滾筒轉(zhuǎn)動產(chǎn)生脈沖信號，并將脈沖信號傳送至積算控制儀表。The belt speed detector unit is installed at the axial end of the driving roller by means of the coder. The rotation of the

28、 roller produces pulse signals that are then transmitted to the integrating control instrument.驅(qū)動單元的主電機根據(jù)積算控制儀表和變頻器信號自動調(diào)速轉(zhuǎn)動，從而使得給料機的輸送量與設定的輸送量一致。The main electric motor of the driving unit automatically rotates with the speed regulated according to the integrating control instrument and the signals

29、of inverter so as to attain the feeding amount of the feeding machine consistent to the set feeding amount. 主電動機與減速箱安裝一體，然后安裝在給料機的驅(qū)動滾筒上。變頻器根據(jù)積算控制儀表的衡定的輸送量信號產(chǎn)生相應的頻率，主電機根據(jù)不同的頻率，產(chǎn)生不同的轉(zhuǎn)速。也就是說驅(qū)動滾筒產(chǎn)生相應的轉(zhuǎn)速。從而達到輸送機的輸送量衡定，即與設定的輸送量一致。The main electromotor and the gear box are installed in one entity, and then

30、 installed on the driving roller of the feeding machine. The inverter produces corresponding frequency according to the signals of feeding amount scaled by the integrating control instrument, while the main electromotor produces different rotating speeds according to different frequencies. That is t

31、o say that the driving roller produces corresponding rotating speed so as to scale the feeding amount of the feeding machine, which is consistent to the set feeding amount. 積算控制儀表對傳感器的稱重（重量）電壓信號和測速傳感器的速度脈沖信號進行處理和計算。積算控制儀表通過比例關(guān)系的運算將速度脈沖信號轉(zhuǎn)換成輸送帶每秒鐘運行的長度，即輸送帶的速度。儀表對稱重傳感器（單位長度重量）和馬達（皮帶每秒鐘運行的距離）信號進行積分，得到

32、輸送機每秒鐘的輸送量。每秒鐘的輸送量同設定的輸送量進行逐次比較，其差值信號反饋給變頻器，變頻器產(chǎn)生相應的頻率用于調(diào)節(jié)馬達的轉(zhuǎn)速（輸送膠帶速度），直到真實流量和設定量相一致。The integrating control instrument carries on treatment and calculation toward the weighing (weight) voltage signals of the transducer and the speed pulse signals of the speed measuring transducer and then converts

33、 the speed pulse signals into the running length of the conveyer belt per second through a proportional operation, namely the speed of the conveyer belt. The instrument conducts integral calculation toward the weighing transducer (the weight in a unit length) and the motor signals (the running dista

34、nce of the conveyer belt per second) so as to attain the feeding amount of the conveyer belt per second. The feeding amount per second is successively compared with the set feeding amount and the difference signals are fed back to the inverter. The corresponding frequencies produced by the inverter

35、are applied to adjust the motors rotating speed (speed of the conveyer belts rubber belt ) until the real feeding flux is consistent to the set feeding amount. 積算控制儀表同時能夠?qū)⒚棵腌姷妮斔土考皶r地轉(zhuǎn)換成每小時的輸送量用負荷率的形式顯示出來。同時控制儀表具有強大的通訊功能和數(shù)據(jù)儲存功能。（詳細資料參見儀表說明書）At the same time the integrating control instrument can timel

36、y convert the feeding amount per second into the feeding amount per hour that then is displayed in the form of load rate.
