卷?yè)P(yáng)機(jī)的應(yīng)用及發(fā)展摘要：本文簡(jiǎn)要介紹了卷?yè)P(yáng)機(jī)的應(yīng)用領(lǐng)域，卷?yè)P(yáng)機(jī)結(jié)構(gòu)組成及特點(diǎn)，卷?yè)P(yáng)機(jī)的作用以及使用時(shí)的注意事項(xiàng)。國(guó)內(nèi)外卷?yè)P(yáng)機(jī)的發(fā)展?fàn)顩r。通過(guò)這些對(duì)卷?yè)P(yáng)機(jī)有一個(gè)大致的了解，為設(shè)計(jì)做準(zhǔn)備。關(guān)鍵詞：卷?yè)P(yáng)機(jī)，應(yīng)用，國(guó)內(nèi)外，發(fā)展前言卷?yè)P(yáng)機(jī)又叫絞車(chē)，是由人力或機(jī)械動(dòng)力驅(qū)動(dòng)卷筒、卷繞繩索來(lái)完成牽引工作的裝置。可以垂直提升、水平或傾斜拽引重物。卷?yè)P(yáng)機(jī)分為手動(dòng)卷?yè)P(yáng)機(jī)和電動(dòng)卷?yè)P(yáng)機(jī)兩種?，F(xiàn)在以電動(dòng)卷?yè)P(yáng)機(jī)為主。電動(dòng)卷?yè)P(yáng)機(jī)由電動(dòng)機(jī)、聯(lián)軸節(jié)、制動(dòng)器、減速器和卷筒組成，共同安裝在機(jī)架上。對(duì)于起升高度和裝卸量大工作頻繁的情況，調(diào)速性能好，能令空鉤快速下降。在很久以前的古代，就知道來(lái)用轆轤等來(lái)提升重物，以減輕體力勞動(dòng)的強(qiáng)度和提高勞動(dòng)生產(chǎn)率。1. 國(guó)內(nèi)卷?yè)P(yáng)機(jī)的應(yīng)用與發(fā)展在我國(guó)，解放前卷?yè)P(yáng)機(jī)只有在一些大型企業(yè)中才被使用，應(yīng)用很少，而且所使用的卷?yè)P(yáng)機(jī)也均為國(guó)外生產(chǎn)，國(guó)內(nèi)基本上沒(méi)有生產(chǎn)卷?yè)P(yáng)機(jī)的廠家。我國(guó)卷?yè)P(yáng)機(jī)的生產(chǎn)是解放后才開(kāi)始的。50 年代為滿(mǎn)足恢復(fù)經(jīng)濟(jì)的需要和第一個(gè)五年計(jì)劃的得要，卷?yè)P(yáng)機(jī)的生產(chǎn)被提到了日程上。原沈陽(yáng)國(guó)泰機(jī)器廠(阜新礦山機(jī)械廠前身)等成批仿制了兩種卷?yè)P(yáng)機(jī)，一種為日本的 JIS8001 型動(dòng)力卷?yè)P(yáng)機(jī)，它是一種原動(dòng)機(jī)為電動(dòng)機(jī)動(dòng)型式是開(kāi)式圓柱齒輪傳動(dòng)，雙錐體摩擦離合器，操作為手扳腳踩的快速卷?yè)P(yáng)機(jī)，另一種是按蘇聯(lián)圖紙制造的 1011 型和 1012 型普通蝸桿傳動(dòng)、電控慢速卷?yè)P(yáng)機(jī)。由于當(dāng)時(shí)生產(chǎn)力不高，卷?yè)P(yáng)機(jī)的需求量亦不多，故這段時(shí)間國(guó)內(nèi)卷?yè)P(yáng)機(jī)的生產(chǎn)主要是仿制。 隨著生產(chǎn)力的發(fā)展，到了 60 年代，卷?yè)P(yáng)機(jī)的生產(chǎn)和使用越來(lái)越多。為了協(xié)調(diào)生產(chǎn)，卷?yè)P(yáng)機(jī)主要生產(chǎn)廠家( 阜新礦山機(jī)械廠、天津卷?yè)P(yáng)機(jī)廠、山西機(jī)器廣、寶雞起重運(yùn)輸機(jī)廠等)組成了卷?yè)P(yáng)機(jī)行業(yè)組織，隸屬于第一機(jī)械工業(yè)部礦山機(jī)械行業(yè)。為了發(fā)展卷?yè)P(yáng)機(jī)的生產(chǎn)，行業(yè)組織了有關(guān)廠家的人員對(duì)全國(guó)卷?yè)P(yáng)機(jī)的生產(chǎn)相應(yīng)用情況進(jìn)行了調(diào)查。在調(diào)查的基礎(chǔ)上，黃 河 科 技 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (文 獻(xiàn) 綜 述 ) 第 2 頁(yè) 開(kāi)始自行設(shè)計(jì)和制造新的卷?yè)P(yáng)機(jī)，先后試制了 0.5t、lt、3t 電動(dòng)卷?yè)P(yáng)機(jī)，但由于對(duì)當(dāng)時(shí)各廠家的生產(chǎn)能力估計(jì)不足，無(wú)法推廣。從 70 年代起，我國(guó)卷?yè)P(yáng)機(jī)的生產(chǎn)進(jìn)入了技術(shù)提高、品種增多的新階段。在各廠自行設(shè)計(jì)和生產(chǎn)的基礎(chǔ)上，1973 年，由卷?yè)P(yáng)機(jī)行業(yè)組織了有關(guān)廠家和院校聯(lián)合進(jìn)行了卷?yè)P(yáng)機(jī)基型設(shè)計(jì)，并充分考慮到了當(dāng)時(shí)中小廠家的生產(chǎn)能力。快速卷?yè)P(yáng)機(jī)的基型采用半開(kāi)半閉式齒輪傳動(dòng)，離合器采用單錐面石棉橡膠摩擦帶結(jié)構(gòu)，操縱用手板剎車(chē)帶制動(dòng)。慢速卷?yè)P(yáng)機(jī)的基型式為閉式傳動(dòng)(圓柱齒輪傳動(dòng)或蝸桿傳動(dòng)減速器)、電磁鐵制動(dòng)結(jié)構(gòu)。這兩種基型一直到現(xiàn)今還在生產(chǎn)。為適應(yīng)生產(chǎn)發(fā)展的需要，當(dāng)時(shí)第一機(jī)械工業(yè)部發(fā)布了 JB926—74《卷?yè)P(yáng)機(jī)型式與基本參數(shù) 》和 JBl803—76《卷?yè)P(yáng)機(jī)技術(shù)條件》兩個(gè)部標(biāo)準(zhǔn)，并把卷?yè)P(yáng)機(jī)行業(yè)劃歸常德機(jī)械研究所(長(zhǎng)沙機(jī)械研究院前身)領(lǐng)導(dǎo)。隨著部標(biāo)準(zhǔn)的頒布，使卷?yè)P(yáng)機(jī)有了大發(fā)展的基礎(chǔ)。在此期間，由于石化工業(yè)的發(fā)展，大型設(shè)備很多，都需要吊裝，如一些大型反應(yīng)塔，塔的高度達(dá)七八十米，質(zhì)量達(dá)五六百?lài)?，就需要有大型吊裝用的卷?yè)P(yáng)機(jī)，因而各廠家相繼生產(chǎn)了 20t 和 32t 卷?yè)P(yáng)機(jī)，滿(mǎn)足了經(jīng)濟(jì)發(fā)展的需要。80 年代以后，各種競(jìng)爭(zhēng)機(jī)制的引入，科技是第一生產(chǎn)力的概念逐漸被人們所認(rèn)識(shí)，所接受。是我國(guó)卷?yè)P(yáng)機(jī)設(shè)計(jì)制造技術(shù)發(fā)展最快的時(shí)期。國(guó)家也制定了有關(guān)卷?yè)P(yáng)機(jī)的配套標(biāo)準(zhǔn)、規(guī)范。新產(chǎn)品種數(shù)近十個(gè)，其中最具有代表性的產(chǎn)品有福建省建筑機(jī)械廠的行星傳動(dòng)卷?yè)P(yáng)機(jī)、昆明建筑機(jī)械廠的少齒差傳動(dòng)卷?yè)P(yáng)機(jī)、長(zhǎng)沙建筑機(jī)械研究所與福州市建筑機(jī)械廠聯(lián)合開(kāi)發(fā)的仿日本

Seibu 一字型卷?yè)P(yáng)機(jī)，使我國(guó)的建筑卷?yè)P(yáng)機(jī)技術(shù)跨人世界先進(jìn)行列。1991 年 10 月通過(guò)的省科委組織的專(zhuān)家鑒定意見(jiàn)：該產(chǎn)品整機(jī)組合合理、結(jié)構(gòu)緊湊、重量輕、過(guò)載能力強(qiáng)、工作安全可靠，與同類(lèi)產(chǎn)品相比，居國(guó)內(nèi)先進(jìn)水平，其中傳動(dòng)方式部分的設(shè)計(jì)構(gòu)思獨(dú)特、新穎，受力均勻、合理，屬?lài)?guó)內(nèi)外首創(chuàng)。進(jìn)入新世紀(jì)以來(lái)，各行各業(yè)都有飛速發(fā)展，近些年數(shù)控機(jī)床的廣泛應(yīng)用，信息技術(shù)和數(shù)控技術(shù)日趨成熟，使得機(jī)械制造的效率提高、成本降低，這些都將推動(dòng)卷?yè)P(yáng)機(jī)工業(yè)的發(fā)展。黃 河 科 技 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (文 獻(xiàn) 綜 述 ) 第 3 頁(yè) 2. 國(guó)外卷?yè)P(yáng)機(jī)的應(yīng)用與發(fā)展在國(guó)外，卷?yè)P(yáng)機(jī)的品種繁多，應(yīng)用也很廣泛，在西方技術(shù)先進(jìn)的國(guó)家，雖然工業(yè)水平先進(jìn)，機(jī)械化程度不斷提高，起重設(shè)備也不斷更新，但仍不能淘汰掉這樣的行之有效的簡(jiǎn)單機(jī)械設(shè)備，下面介紹一下幾個(gè)主要國(guó)家生產(chǎn)卷?yè)P(yáng)機(jī)的狀況。（一）美國(guó)美國(guó)生產(chǎn)卷?yè)P(yáng)機(jī)的廠家有近百家，主要有貝波（BEEBE）國(guó)際有限公司，哲思（THERN）有限公司等。貝波國(guó)際有限公司是美國(guó)較大的生產(chǎn)起重設(shè)備的公司，主要產(chǎn)品有各種手動(dòng)卷?yè)P(yáng)機(jī)，電動(dòng)卷?yè)P(yáng)機(jī)，提升機(jī)械及起重機(jī)。手動(dòng)卷?yè)P(yáng)機(jī)重要品種有蝸桿傳動(dòng)系列，直齒圓柱齒輪系列，齒輪蝸桿傳動(dòng)組合系列，直接驅(qū)動(dòng)系列，鏈傳動(dòng)系列。其中直間驅(qū)動(dòng)式電動(dòng)卷?yè)P(yáng)機(jī)的傳動(dòng)是全封閉行星齒輪傳動(dòng)，傳動(dòng)系列全部全部安裝在卷筒里面，機(jī)架和卷筒用高強(qiáng)度鋼焊接而成 。（二）日本日本從明治 30 年開(kāi)始制造和使用卷?yè)P(yáng)機(jī)。據(jù)日本荷役機(jī)械研究所設(shè)計(jì)，1970~1975 年間卷?yè)P(yáng)機(jī)的產(chǎn)量增加 62.5%。據(jù)日本通產(chǎn)省機(jī)械核計(jì)月報(bào)載,接年單純土卷?yè)P(yáng)機(jī)的產(chǎn)量就達(dá) 12 萬(wàn)臺(tái),生產(chǎn)值約 100 億日元。日本卷?yè)P(yáng)機(jī)行業(yè)由機(jī)械技術(shù)部會(huì),荷役機(jī)械技術(shù)委員會(huì)領(lǐng)導(dǎo).主要生產(chǎn)廠家有北川鐵工所,遠(yuǎn)藤鋼機(jī),南星,越野總業(yè),松崗產(chǎn)業(yè)等 80 多個(gè)產(chǎn)業(yè)。（三）法國(guó)法國(guó)生產(chǎn)卷?yè)P(yáng)機(jī)的廠家很多，其中包藤（POTAIN）公司就是生產(chǎn)卷?yè)P(yáng)機(jī)的主要商家之一。包藤公司主要生產(chǎn) KUSW 系列卷?yè)P(yáng)機(jī)，LMD 系列卷?yè)P(yáng)機(jī)，PC 系列卷?yè)P(yáng)機(jī)和 RCS系列卷?yè)P(yáng)機(jī)。（四）國(guó)外卷?yè)P(yáng)機(jī)的發(fā)展史1、大型化由于基礎(chǔ)工業(yè)的發(fā)展，大型設(shè)備和建筑構(gòu)件要求整體安裝，促進(jìn)了大型卷?yè)P(yáng)機(jī)的發(fā)展。目前，俄羅斯已生產(chǎn)了 60t

electric motor converts electricity into mechanical motion. Electric motors are used in household appliances, electric fans, remote-controlled toys, and in thousands of other applications. The electric motor grew out of one of the earliest discoveries in electric science—Arago’s rotations. In 1824, Francois Arago discovered that a magnetic needle suspended over a copper disk would rotate when the disc was spun. The next year, computer pioneer Charles Babbage and astronomer John Herschel showed that the action could be reversed: spinning a more powerful magnet above the copper disk would spin the copper disc. Then, in 1831, Michael Faraday conducted experiments that helped explain why this took place. While this laid the groundwork for the electric motor, it was another half century before electric motors were doing useful work. Over the next few decades many inventors made improved devices for turning electricity into motion. One of these was Hippolyte Pixii’s 1832 improvement called the commutator, which switched the flow of current between two or more sets of stationary electromagnets to keep a motor continuously rotating. Thomas Davenport was the first to build an electric motor large enough to be used in industry, and he was also the first to seek a patent on a motor. Soon electric motors were being used for such things as transportation. Moritz-Hermann De Jacobi used an electric motor on a boat on the Neva River, and Charles G. Page used one to build a small locomotive. After the appearance of commercial electric power systems in the 1880s, 黃 河 科 技 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (文 獻(xiàn) 翻 譯 ) 第 2 頁(yè)larger electric motors were possible. Edison encouraged the use of electric motors in industrial applications and designed several new electric motors for that purpose. An important change came in the later 1880s and 1890s, when electric power companies began considering the switch to alternating current. Alternating current was perfect for the distribution of electric power over long distances, and it worked well with the Edison electric lamp, but no practical AC motor existed until the works of Galileo Ferraris in Italy and Nikola Tesla in the United States. Tesla’s contributions are remembered today more than Ferraris’ in part because Tesla was subsequently hired by the Westinghouse corporation, which used his patents along with many others to become one of the major producers of electric equipment. With a suitable AC motor available, AC power took off. It is still in use today.ServomotorServomotors are available as AC or DC motors. Early servomotors were generally DC motors because the only type of control for large currents was through SCRs for many years. As transistors became capable of controlling larger currents and switching the large currents at higher frequencies, the AC servomotor became used more often. Early servomotors were specifically designed for servo amplifiers. Today a class of motors is designed for applications that may use a servo amplifier or a variable-frequency controller, which means that a motor may be used in a servo system in one application, and used in a variable-frequency drive in another application. Some companies also call any closed-loop system that does not use a stepper motor a servo system, so it is possible for a simple AC induction motor that is connected to a velocity controller to be called a servomotor.Some changes that must be made to any motor that is designed as a servomotor includes the ability to operate at a range of speeds without overheating, the ability to operate at zero speed and retain sufficient torque to hold a load in position, and the ability to operate at very low speeds for long periods of time without overheating. Older-type motors have cooling fans that are connected directly to the motor shaft. When the motor runs at slow speed, the fan does not move enough air to cool the motor. Newer motors have a separate fan mounted so it will provide optimum cooling air. This fan is powered by a constant voltage source so that it will turn at maximum RPM at all times regardless of the speed of the servomotor. One of the 黃 河 科 技 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (文 獻(xiàn) 翻 譯 ) 第 3 頁(yè)most usable types of motors in servo systems is the permanent magnet (PM) type motor. The voltage for the field winding of the permanent magnet type motor can be AC voltage or DC voltage. The permanent magnet-type motor is similar to other PM type motors presented previously. Figure-1 shows a cutaway picture of a PM motor and Fig.-2 shows a cutaway diagram of a PM motor. From the picture and diagram you can see the housing, rotor and stator all look very similar to the previous type PM motors. The major difference with this type of motor is that it may have gear reduction to be able to move larger loads quickly from a stand still position. This type of PM motor also has an encoder or resolver built into the motor housing. This ensures that the device will accurately indicate the position or velocity of the motor shaft.FIGURE 1-1 Typical PM servomotorsFIGURE 1-2 Cutaway picture of a permanent magnet servomotor黃 河 科 技 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (文 獻(xiàn) 翻 譯 ) 第 4 頁(yè)Brushless ServomotorsThe brushless servomotor is designed to operate without brushes. This means that the commutation that the brushes provided must now be provided electronically. Electronic commutation is provided by switching transistors on and off at appropriate times. Figure 1-3 shows three examples of the voltage and current waveforms that are sent to the brushless servomotor. Figure 1-4 shows an example of the three windings of the brushless servomotor. The main point about the brushless servomotor is that it can be powered by either ac voltage or dc voltage. FIGURE 1-3 (a) Trapezoidal input voltage and square wave current waveforms. (b) Sinusoidal input voltage and sinusoidal voltage and square wave output voltage waveforms. (c) Sinusoidal input voltage and sinusoidal current waveforms. This has become the most popular type of brushless servomotor control.黃 河 科 技 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (文 獻(xiàn) 翻 譯 ) 第 5 頁(yè)Figure 1-4 shows three sets of transistors that are similar to the transistors in the output stage of the variable-frequency drive. In Fig. l-4a the transistors are connected to the three windings of the motor in a similar manner as in the variable-frequency drive. In Fig. l-4b the diagram of the waveforms for the output of the transistors is shown as three separate sinusoidal waves. The waveforms for the control circuit for the base of each transistor are shown in Fig. l-4c. Figure l-4d shows the back EMF for the drive waveforms. FIGURE 11-86 (a) Transistors connected to the three windings of the brushless servomotor. (b) Waveforms of the three separate voltages that are used to power the three motor windings. (c) Waveforms of the signals used to control the transistor sequence that provides the waveforms for the previous diagram, (d) Waveform of the overall back EMFServomotor Controllers Servomotor controllers have become more than just amplifiers for a servomotor. Today servomotor controllers must be able to make a number of decisions and provide a means to receive signals from external sensors and controls in the system, and send signals to host 黃 河 科 技 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (文 獻(xiàn) 翻 譯 ) 第 6 頁(yè)controllers and PLCs that may interface with the servo system. Figure 1-5 shows a picture of several servomotors and their amplifiers. The components in this picture look similar to a variety of other types of motors and controllers. FIGURE 1-5 Example servomotors and amplifiersFigure 1-6 shows a diagram of the servomotor controller so that you can see some of the differences from other types of motor controllers. The controller in this diagram is for a DC servomotor. The controller has three ports that bring signals in or send signals out of the controller. The power supply, servomotor, and tachometer are connected to port P3 at the bottom of the controller. You can see that the supply voltage is 115-volt AC single phase. A main disconnect is connected in series with the LI wire. The LI and N lines supply power to an isolation step-down transformer. The secondary voltage of the trans-former can be any voltage between 20 and 85 volts. The controller is grounded at terminal 8. You should remember that the ground at this point is only used to provide protection against short circuits for all metal parts in the system. The servomotor is connected to the controller at terminals 4 and 5. Terminal 5 is + and terminal 4 is - . Terminal 3 provides a ground for the shield of the wires that connect the motor and the controller. The tachometer is connected to terminals 1 and 2. Terminal 2 is + and terminal 1 is - . The shield for this cable is grounded to the motor case. The wires connected to this port will be larger than wires connected to the other ports, since they must 黃 河 科 技 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (文 獻(xiàn) 翻 譯 ) 第 7 頁(yè)be capable of carrying the larger motor current. If the motor uses an external cooling fan, it will be connected through this port. In most cases the cooling fan will be powered by single-phase or three-phase AC voltage that remains at a constant level, such as 110 volts AC or 240 volts AC. FIGURE 1-6 Diagram of a servo controller. This diagram shows the digital (on-off) signals and the analog signals that are sent to the controller, and the signals the controller sends back to the host controller or PLC.The command signal is sent to the controller through port PI. The terminals for the command signal are 1 and 2. Terminal 1 is + and terminal 2 is - . This signal is a type signal, which means that it is not grounded or does not share a ground potential with any other part of the circuit. Several additional auxiliary signals are also connected through port 1. These signals include inhibit (INH), which is used to disable the drive from an external controller, and forward and reverse commands (FAC and RAC), which tell the controller to send the voltage to the motor so that it will rotate in the forward or reverse direction. In some applications, the forward maximum travel limit switch and reverse maximum travel limit 黃 河 科 技 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (文 獻(xiàn) 翻 譯 ) 第 8 頁(yè)switch are connected so that if the machine travel moves to the extreme position so that it touches the overtravel limit switch, it will automatically energize the drive to begin travel in the opposite direction. Port PI also provides several digital output signals that can be used to send fault signals or other information such as "drive running" back to a host controller or PLC. Port PI basically is the interface for all digital (on-off) signals. Port P2 is the interface for analog (0-max) signals. Typical signals on this bus include motor current and motor velocity signals that are sent from the servo controller back to the host or PLC where they can be used in verification logic to ensure the controller is sending the correct information to the motor. Input signals from the host or PLC can also be sent to the controller to set maximum current and velocity for the drive. In newer digital drives, these values are controlled by drive parameters that are programmed into the drive. PWM Servo Amplifier The PWM servo amplifier is used on small-size servo applications that use DC brush-type servomotors. Figure 1-7 shows a diagram for this type of amplifier. From the diagram you can see that single-phase AC power is provided to the amplifier as the supply at the lower left part of the diagram. The AC voltage is rectified and sent to the output section of the drive that is shown in the top right comer of the diagram. The output section of the drive uses four IGBTs to create the pulse-width modulation waveform. The IGBTs are connected so that they provide 30-120 volts DC and up to 30 A to the brush-type DC servo-motor. The polarity of the motor is indicated in the diagram. The remaining circuits show a variety of fault circuits in the middle of the diagram that originate from the fault logic board and provide an output signal at the bottom of the diagram. You should notice that the fault output signals include overvoltage, overtemperature, and overcurrent. A fourth signal is identified as SSO (system status output), which indicates the status of the system as faulted anytime a fault has occurred. A jumper is used to set the SSO signal as an open collector output with a logic level "1" indicating the drive is ready, or as a normally closed relay indicating the drive is ready. 黃 河 科 技 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (文 獻(xiàn) 翻 譯 ) 第 9 頁(yè)The input terminals at the bottom right part of the diagram are used to enable or inhibit the drive, and to select forward amplifier clamp (FAC) or reverse amplifier clamp (RAC). The inhibit signal is used as a control signal, since it inhibits the output stage of the amplifier if it is high. The FAC and RAC signals limit the current in the opposite direction to 5%. The input signals are shown in the diagram at the upper left side. The VCS (velocity command signal) requires a +VCS and a -VCS signal to provide the differential signal. FIGURE 1-7 Diagram of a pulse-width modulator (PWM) amplifier with a brush-type DC servomotorApplications for Servo Amplifiers and Motors You will get a better idea of how servomotors and amplifiers operate if you see some typical applications. Figure 1-8 shows an example of a servomotor used to control a press feed. In this application sheet material is fed into a press where it is cut off to length with a knife blade or sheer. The sheet material may have a logo or other advertisement that must line up registration marks with the cut-off point. In this application the speed and position of the sheet material must be synchronized with the correct cut-off point. The feed-back sensor could be an encoder or resolver that is coupled with a photoelectric sensor to determine the 黃 河 科 技 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (文 獻(xiàn) 翻 譯 ) 第 10 頁(yè)location of the registration mark. An operator panel is provided so that the operator can jog the system for maintenance to the blades, or when loading a new roll of material. The operator panel could also be used to call up parameters for the drive that correspond to each type of material that is used. The system could also be integrated with a programmable controller or other type of controller and the operator panel could be used to select the correct cutoff points for each type of material or product that is run. FIGURE 1-8 Application of a servomotor controlling the speed of material as it enters a press for cutting pieces to size.An Example of a Servo Controlled In-Line Bottle-Filling ApplicationA second application is shown in Fig. 1-9. In this application multiple filling heads line up with bottles as they move along a continuous line. Each of the filling heads must match up with a bottle and track the bottle while it is moving. Product is dispensed as the nozzles move with the bottles. In this application 10 nozzles are mounted on a carriage that is driven by a ball-screw mechanism. The ball-screw mechanism is also called a lead screw. When the motor turns the shaft of the ball screw, the carriage will move horizontally along the length of 黃 河 科 技 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (文 獻(xiàn) 翻 譯 ) 第 11 頁(yè)the ball-screw shaft. This movement will be smooth so that each of the nozzles can dispense product into the bottles with little spillage. The servo drive system utilizes a positioning drive controller with software that allows the position and velocity to be tracked as the conveyor line moves the bottles. A master encoder tracks the bottles as they move along the conveyor line. An auger feed system is also used just prior to the point where the bottles enter the filling station. The auger causes a specific amount of space to be set between each bottle as it enters the filling station. The bottles may be packed tightly as they approach the auger, but as they pass through the auger their space is set exactly so that the necks of the bottles will match the spacing of the filling nozzles. A detector is also in conjunction with the dispensing system to ensure that no product is dispensed from a nozzle if a bottle is missing or large spaces appear between bottles. FIGURE 1-9 Application of a beverage-filling station controlled by a servomotorThe servo drive system compares the position of the bottles from the master encoder to the feedback signal that indicates the position of the filling carriage that is mounted to the ball screw. The servo drive amplifier will increase or decrease the speed of the ball-screw mechanism so that the nozzles will match the speed of the bottles exactly. An Example of a Servo Controlled Precision Auger Filling System 黃 河 科 技 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (文 獻(xiàn) 翻 譯 ) 第 12 頁(yè)A third application for a servo system is provided in Fig. 1-10. In this application a large filling tank is used to fill containers as they pass along a conveyor line. The material that is dispensed into the containers can be a single material fill or it can be one of several materials added to a container that is dumped into a mixer for a blending operation. Since the amount of material that is dispensed into the container must be accurately weighed and metered into the box, an auger that is controlled by a servo system is used. The feedback sensor for this system can be a weighing system such as the load cell discussed in earlier chapters. The command signal can come from a programmable controller or the operator can enter it manually by selecting a recipe from the operator's terminal. The amount of material can be different from recipe to recipe. FIGURE 1-10 Application of a precision auger filling station controlled by a servomotor.The speed of the auger can be adjusted so that it runs at high speed when the container is first being filled, and the speed can be slowed to a point where the final grams of material can be metered precisely as the container is filled to the proper point. As the price of material 黃 河 科 技 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (文 獻(xiàn) 翻 譯 ) 第 13 頁(yè)increases, precision filling equipment can provide savings as well as quality in the amount of product used in the recipe. An Example of a Label Application Using Servomotors The fourth application has a servomotor controlling the speed of a label-feed mechanism that pulls preprinted labels from a roll and applies them to packages as they move on a continuous conveyor system past the labeling mechanism. The feedback signals are provided by an encoder that indicates the location of the conveyor, tach generator that indicates the speed of the conveyor, and a sensor that indicates the registration mark on each label. The servo positioning system is controlled by a microprocessor that sets the error signal, and the servo amplifier that provides power signals to the servomotor. This application is shown in Fig. 1-11. FIGURE 1-11 Example of a labeling application controlled by a servomotorAn Example of a Random Timing Infeed System Controlled by a Servomotor The fifth application is presented in Fig. 1-12, and it shows a series of packaging equipment that operates as three separate machines. The timing cycle of each station of the packaging system is independent from the others. The packaging system consists of an infeed conveyor, a positioning conveyor, and a wrapping station. The infeed conveyor and the wrapping station are mechanically connected so that they run at the same speed. The position of the packages on the wrapping station must be strictly controlled so that the packages do not become too close to each other. A piece of metal called a flight is connected to the wrapping 黃 河 科 技 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (文 獻(xiàn) 翻 譯 ) 第 14 頁(yè)station conveyor at specific points to ensure each package stays in position.
