最近,许多用户比较关心如何选择合理的软硬件构成一个经济、实用的粉体、液体等原料自动配料系统。我司有幸承接、应用了这一类自动配料项目,现将这方面的有关情况简述,供与同行交流、切磋。 _________________________________________ 〖厦门光沃自动化设备有限公司 竭诚为您服务〗 〖联系人:欧先生 〗〖手机:() 〗〖: 〗〖传真: 【价格】如此低价,一家 【货期】大量现货,下单后即可发货【质量】全新原装,进口***【保障】产品经过专业检测,质保一年,15天包退换【品牌】Allen-Bradley罗克韦尔、ABB、本特利Bently 3500系统卡件、GE、艾默生西屋等模块卡件______________________________________________ ◆系统控制器件选型:采用台湾永宏PLC高功能主机:FBS-32MC、台湾威纶5.6彩色触摸屏: MT506M与梅特勒-托利多称重控制仪共同组成配料系统控制主件,称重控制仪的去皮、清皮和归零通过通讯给定。
◆PLC选型依据 :
1)具有足够大的暂存器空间且提供档案暂存器空间,保证系统的配料配方量足够多足够大,透过专用指令操作保证配方的安全
2)通讯功能强大,通讯协议编程简单方便
3)可扩展多个通讯口,为系统延伸控制与联网提供硬件支持
4)经济实惠,运行可靠稳定性要好
二、系统构成
该系统由4个储料槽及计量槽构成,由称重控制仪驱动,按生产流程依次为储料控制、落料控制、搅拌控制、计量控制、卸料控制,系统构成如下图(简化): ◆配料策略如下:
1、当配料按钮按下时,启动配料
2、确认计量槽清空,重量归零
3、半闭卸料阀112,开启配原料A101,直到原料A101达到设定值时(即原料A101=秤当前重量减去空秤皮重),关闭原料A101配料,延时1秒搅拌系统工作,一定时间后启动配原料A102标志位。
4、当配原料A102标志成立时,开启配原料A102,开始配原料A102,直到原料A102达到设定值时(即原料A102=秤当前重量减去空秤皮重再减去原料A102重量),关闭原料A102配料,延时1秒搅拌系统工作,一定时间后启动配下一配料标志位。以此类推至完成配方。 DP Vacuum Pump Gas Module Aworking
