控制系统。首先,客户可以从三种不同的加料机控制器中进
行挑选。随后,可挑选不同的集中输送控制系统: SELVAC
2是一种简单并且经受了时间考验的系统,提供了价格实惠的
解决方案。METROnet S被看成是作为Soft PLC控制的标准
输送系统的一部分。METROnet A 旗舰版的网络兼容工具用
于复杂的输送系统。不管是Soft PLC或西门子 S7 PLC,采用
WEBpanel 或者是分散的CAN总线节点均可适用。所有
METROnet控制系统完全结合在CONTROLnet平台上,可以
经由以太网络联络其它控制器。
同步计量单元可精确地改进配方
正如METRO G 单元一样,历经考验而可靠的卡勒多尼
机械与高质量摩丹控制相融合,使得MINIBLEND V 具有了新
的特性。容积式计量和混合单元MINIBLEND V 设计目标是用
于自由流动和常规流动的物料,不管是生产透明的还是不透
明的部件,都有很理想的效果。MINIBLEND作为添加剂计量
单元,适合于注射模塑和挤出方面的应用。
作为同步计量单元,MINIBLEND V 提供了极为出色的
配比精度和可重复性,任何时间都可以追溯配方。添加剂垂
直喂入,依靠重力通过单元里的Y型混合器然后进入加工设备
的喂料口。 这可防止物料堆积和架桥效应。主物料和添加剂
只有在进入加工设备的喂料口之前才结合。仅仅在这一个位
置才共同流动并进行均匀的混合,不会有物料的离析 。
圆盘计量特殊的好处在于计量的一致性。与螺杆式计量
单元相比较,在产量为0.5 到 5 kg/h 这一计量范围内,盘式
计量的一致性要高出一倍。计量圆盘可以有三种不同的类型
(可选择耐磨型),计量范围从0.05 到 10.5 kg/h(容积密度
0.6 kg/h)。当对非常小的产量进行计量时,单个颗粒就可以
对混合精度产生巨大的影响。为避免出现这一问题,所有计
量圆盘都安装了切粒装置。这样就可以将粒子切割为小片,
以便对最小的产量进行一致的计量。
无刷电机可以非常方便地拆卸,不需要工具,配备有完
善的电机管理方式,提供免维护和可靠的连续运行。通过
CAN总线技术实现控制通讯。电机单元可以采用摩丹容积式
VOLU MC 或 VOLUnet MC进行控制操作。VOLU MC 控制是
一种经济实惠的容积式浓缩母料计量方案。而现代化的
following processing step when there is a
particularly high demand for material quali-
ty. METRO G material loaders allow the con-
figuration of a suitable conveying system for
every individual requirement.
The METRO G material loaders can be ope-
rated either with a cost effective solution or
right up to an innovative state-of-the-art
controls system. To begin with, the customer
can choose between three different loader
controls. Furthermore, different centralized
conveying controls are available: SELVAC 2 is
a simple and time-tested electronic system
which provides an economically priced solu-
tion. The METROnet S is considered part of
the standard conveying systems as a soft
PLC conveying control. The ultimate, net-
work-compatible tool for complex convey-
ing systems is the METROnet A, either with
soft PLC or Siemens S7 PLC, with WEBpanel,
and decentral CAN-bus nodes. All METRO-
net controls are completely integrated into
the CONTROLnet platform and can be networked with other
controls via Ethernet.
Synchronous dosing units improve recipe accuracy
Just like with the METRO G, time-tested and reliable colortronic
mechanics have been combined with high-quality motan con-
trols and have been extended with additional features for the
MINIBLEND V. The volumetric dosing and mixing unit MINI-
BLEND V was designed for free and normal flowing materials
and is ideal for translucent and opaque parts. As an additive
dosing unit, the MINIBLEND is suitable for injection moulding
and extrusion applications.
As a synchronous dosing unit the MINIBLEND V offers excellent
recipe accuracy and reproducibility, which can be traced at any
time. The additive is fed vertically and is gravity fed into the in-
let of the processing machine through the Y-shaped mixing
throat of the unit. This prevents material buildup and bridging
effects. The main material and the additive combine just before
the inlet of the processing machine. Only at this point do they
flow together to create a homogenous mixture – without ma-
terial segregation.
The particular benefit of disc dosing is the dosing consistency.
Compared to screw dosing units, the dosing consistency at
throughputs of 0.5 to 5 kg/h can be doubled. The dosing discs
are available in three different versions (optional wear resistant
versions) from 0.05 to 10.5 kg/h (bulk density 0.6 kg/h). When
dosing very small throughputs, a single granule can have a
huge effect on the mixture accuracy. In order to solve this pro-
blem, all dosing discs are fitted with a cutting device. This
makes it possible to cut granules into smaller pieces in order to
consistently dose the smallest throughputs.
The brushless motor can be removed very easily and without
tools, and is fitted with integrated motor management, which
provides maintenance-free and reliable continuous operation.
The controls communication occurs via CAN-bus technology.
The unit can be operated with the volumetric motan controls
