Marzoli to display FT6DE roving frame
Hall 1, Booth D9
Marzoli and Marzoli India will exhibit in Hall 1, Booth D9, and will display the FT6DE roving frame, the MTR transport system and Marzoli software platforms for the optimisation of the entire spinning process (YarNet and MRM).
The FT6DE roving frame
A fully-updated version of its market-leading roving frames. The FT6E, 110mm gauge, and FT7E, 130mm gauge, equipped with all the most advanced technology, represent technological excellence for productivity and efficiency.
The drives for the drafting system, the flyers, the spindles and the bobbin rail are independent and coordinated by the central CPU. This simplifies the machine, guaranteeing perfect coordination, reducing the number of components, lowering friction, vibrations and mechanical wear.
The higher number of spindles, the FT6E and FT7E roving frames can respectively reach 224 and 168 spindles, allows to reduce investment and operational costs while boosting productivity per machine. The roving sensors, one for each spinning position, allow to immediately detect any roving break and promptly stop the machine, even in case of roving overlap.
With the release of the new Marzoli roving frame models suction on the roving frame is no longer necessary. This, along with the IE3 premium efficiency motors and an overall design intended to minimize friction, entails an energy saving of 4 Kwh with a substantial reduction of the Kw/Kg ratio.
The FT6E and FT7E roving frames present 3 different options for doffing: semi-automatic doffing, fully-automatic doffing and the new pre-arrangement for automatic doffing upgrade. In the semiautomatic version the bobbin rail lowers and tilts out for easy bobbin collection; there is also a parking for empty tubes just in front of the rail for easy replacement.
In the fully-automatic version full bobbins are collected by the doffer rail and forwarded to the transport system. Empty tubes are inserted on the spindles and brought into working position before the machine restarts. All these operations are carried out automatically, with no human intervention, in less than 3 minutes.
The roving frame with pre-arrangement for the automatic doffing upgrade is a whole new option. Although it grants an easy and fast collection of full bobbins by the operator, it allows to undertake a cost-efficient upgrade to the fully-automatic version at any time.
The MTR transport system
In order to ensure the highest efficiency and output quality standards of its lines Marzoli has launched its own- branded bobbin transport systems with different degrees of automation in order to perfectly suit any customer?s production process.
During India ITME 2016 Marzoli and Marzoli India will display the MTR, the bobbin transport system that best suits spinning mills with standard high-volumes productions.
Several innovations make this product an outstandingly good solution for spinning mills. A stainless steel rail with V shape to prevent dirt accumulation within the rail, an aluminum chain with low load, frame supports with adjustable brackets with screws that allow to easily adjust the height of the rail and correct any misalignment,... However, the greatest innovation that has been introduced with Marzoli transport system is with no doubt the IBC, a bobbin stripper integrated on the exchanger.
Besides the lower investment and maintenance costs, a separated bobbin stripper is no longer necessary, the IBC entails the following benefits:
-The IBC can clean tubes in less than ten seconds, unlike standard bobbin strippers that on average take 20 seconds to clean each tube. This, along with the substantial reduction in the number of stops of the transport chain, allows to boost the efficiency of the entire spinning section.
- With the IBC the bobbin stripper and the exchanger are integrated: there is no need to adjust the relative position of the two devices and there is no mistake in centering of the tubes.
- With the IBC there is less strain on the tubes holders because each tube is collected only once instead of twice.
- In case an empty tube is not cleaned properly, it is not placed on the doffer rail of the roving frame.
- The IBC detects the few roving coils still on the tube and places the ?dirty? tube back on the transport system. This solution prevents downtimes of the roving frame during start up after doffing, allowing a significant increase in efficiency.
YarNet is Marzoli?s production management software which allows the client to control every machine comprising the processes of fiber preparation, spinning preparation and ring spinning.
This product has been designed in order to make production management smart, easy and efficient:
- The software registers and stores all production data, machines operating conditions, machine statuses and technological parameters;
- It allows to elaborate these data with useful functions and obtain valuable information in the form of tables, charts and diagrams;
- It enables the customer to interact directly with the machine by downloading, editing and sending production recipes.
Thanks to YarNet, the customer can rely on just one software to manage the entire plant and when he has to insert a new production recipe, he can do that while sitting in his office instead of standing in front of the idle machine.
Moreover, thanks to the innovative power management function, the operator can compare energy consumption and production levels and find the best trade off. This enables to minimize the incidence of energy costs on yarn production and achieve a sustainable competitive advantage.
MRM is an innovative platform that analyzes the symptomatic data gathered by processors and sensors installed in critical parts of the machines to constantly monitor their efficiency. The data regarding temperatures, power consumption, pressures and vibrations are sent to an IoT platform, provided by Microsoft, where they are analyzed through special algorithms. These algorithms verify that the monitored parameters are inside the machine nominal operating ranges according to the machine working conditions: if they are not, the client is immediately alerted.
The client can also count on the prompt support of Marzoli?s customer service which can access, if necessary, the customer?s machine in order to diagnose the problem and communicate the necessary steps to solve it.
Thanks to the MRM maintenance is no longer based on the experience of few technicians and on standard manuals, but on a great amount of reliable and case-specific information. Some of the main advantages achievable with MRM are: reduction of downtimes, prevention of machine failures, longer running life of the machine components and more effective maintenance of the mill.
Mac3000 Compact system
The new Mac3000 is a highly-innovative, state-of-the-art compact system designed and developed by Marzoli.
Beside being one of the few apron systems with an effective ?auto-cleaning effect? of the apron, which stems from its continuous tension, flexion and relaxation, its compacting zone is perfectly visible. This grants an easy supervision of the core area of the device.
The outstanding compacting performance is also assured by the independent modular suction system with large suction tubes and self-cleaning filter. Together these features guarantee constant suction along the entire length of the machine. Furthermore the speed of the suction motor is settable through inverter so that the right suction amount can always be set according to count, type of fiber, desired efficiency and quality trade-off.
