Change of course in the Zhejiang ChunjiangLight&Textile Industry Group: The Chinesetextile company, founded in 1980, has opted for automation and modern ring spinningmachines designed in Germany for their new production site in Fuyang. The new factory inFuyang is now running 18 ZinserRing 71 ring spinning machines with a total of 21,600spindles. Equipped with CoWeMat, the most reliable doffer in the world, these machineshave reduced personnel requirements to 50% of previous levels.
ZinserRing 71 ring spinning machines
Automation belongs to the future
Until now, Zhejiang Chunjiang Group production was based on ring spinning machines withoutdoffers. A significantly higher personnel requirement per shift, based on highly trained employees,would have been needed with manual machines in the new factory with over 21,000 planned ringspinning spindles. The ZinserRing 71, in contrast, resulted in a reduction in personnel outlay.Due to the increasing shortage of personnel resources, the company therefore decided to usestate-of-the-art ring spinning machines with the automatic doffer. CoWeMat from Zinser.
“Automation belongs to the future”, said company leaders, “and the best partner for automationprojects is Schlafhorst. We have therefore opted for the know-how and the machines fromSchlafhorst for our new factory in Fuyang.”
We are now 15% more productive!
“With the ZinserRing 71 from Schlafhorst, we will have a stronger and highly efficient competitiveposition. We have significantly lower personnel expenditure. We guarantee excellent quality. Andwe have become 15% more productive”, said management of Chunjiang Group.
CoWeMat automatic doffer
Such an increase in competitiveness is only possible when automated processes functionseamlessly. This is ensured with precision technology from Schlafhorst. Doffing is implementedwith proverbial reliability by CoWeMat, the most economical system in the world.
This high-precision technology almost completely prevents gripper malfunctions. In the rare casesthat such a malfunction occurs, the doffer and ring spinning machine simply continue to operatethanks to the safety membrane on the gripper and the independent pneumatic system.
Inspections can be drastically reduced. A light barrier monitors the smooth doffing flow. The cuttingknife even cuts coarse and highly tear-proof yarns.
The precision drive of the BobbinTray system transports bobbins and empty tubes without contactand precisely, thus ensuring high Zinser yarn quality.
“Zinser has over 45 years experience with the CoWeMat and represents the most process-safeand reliable doffer on the market today”, said mill manager, “We produce, shift for shift, more yarnwith minimum personnel expenditure with the ZinserRing 71. ”
CoWeFeed reduces personnel requirements by up to 66%
Up to 66% less personnel is required by Zhejiang Chunjiang Group in the new factory for insertingempty tubes into the ring spinning machine because the ZinserRing 71 is equipped withCoWeFeed. The CoWeFeed automatically sorts the empty tubes before insertion. Personnel cansimply dump empty tubes into the storage container. Time-consuming manual sorting is no longerrequired.
Reproducible quality thanks to central software settings
The ZinserRing 71 also makes the company more independent from personnel with regards toquality issues. The spinning parameters are entered centrally via a touchscreen in the spinningsoftware EasySpin. EasySpin is the safest operating software on the market. It rapidly andprecisely guides the employee with images and symbols to the correct settings. Practical tips arestored for every input screen and illustrated messages provide targeted information aboutnecessary actions.
Operating errors are almost completely excluded. The settings data can be transferred to other ringspinning machines within seconds using a USB stick.
The management consistently relies on powerful, reliable and automated machine technology, thussecuring their market advantage. This new orientation towards automation is continued by ZhejiangChunjiang Group for package winding, where they have invested in a new installation with theAutoconer X5, type D with automatic material flow. The excellent yarn quality of the ZinserRing 71ring spinning machine is ensured by the innovative Schlafhorst winding and splicing technology.
Winding machines with state-of-the-art material flow automation
The company has sworn by the Autoconer from Schlafhorst for years now with regards to windingmachines. Until now, the company has used the type RM machines, which required high personnelexpenditure due to the manual bobbin feed. The Autoconer X5 type D, was ordered for the newfactory and is equipped with the latest state-of-the-art automated material flow.
With their new Autoconer X5 type D, Zhejiang Chunjiang Group has been able to decisivelyincrease their productivity. At the same time, automated bobbin handling means even lesspersonnel expenditure. The Autoconer X5, with their flexibly adaptable configuration, are perfectlysuited to meet demands for higher lot and material flexibility. Intelligent automation aggregates, forexample, the X-Change package doffer, and their unmatched functionality greatly reduce the levelof manual work for the employees. Hardware handling and mechanical settings are reduced to aminimum.
Zhejiang Chunjiang Group can therefore use the best and most productive settings for theirproduction, irrespective of the skill level of their personnel. “The ZinserRing 71 reduces ourpersonnel expenditure for quality assurance”, said top management of Chunjiang Group, “We canproduce quality that impresses our customers, almost at the touch of a button. Our decision wouldbe for the ZinserRing 71 again at any time.”
