Blow molder plunges into CIM.Computer-integrated manufacturing computer-integrated manufacturing
Data-driven automation that affects all systems or subsystems within a manufacturing environment: design and development, production (see CAD/CAM), marketing and sales, and field support and service. or CIM (1) (Computer-Integrated Manufacturing) Integrating office/accounting functions with automated factory systems. Point of sale, billing, machine tool scheduling and supply ordering are part of CIM. is just beginning to come into its own in blow molding. Custom bottle maker Winn Packaging Co. in Fairfield, Ohio Fairfield is a city in Butler County, Ohio, United States, near Cincinnati. The population was 42,097 at the 2000 census. On December 28, 1994, the city withdrew from Fairfield Township.
There was another town named Fairfield, Ohio that was located Northeast of Dayton, Ohio. , is one sign of this emerging trend. A year ago, the company plunged into CIM with a $250,000 investment in real-time process and production monitoring of 15 bottle-making machines. Winn started with the latest Focus 2000 software and hardware from Syscon-PlantStar in South Bend South Bend, city (1990 pop. 105,511), seat of St. Joseph co., N Ind., on the great south bend of the St. Joseph River, in a farming and mint-growing region; inc. as a city 1865. , Ind., the first installation of such a system outside of injection molding injection molding

How did Winn justify such advanced computer integration of a collection of workhorse Battenfeld and Bekum shuttle blow molders, many bought used ranging in age from two to 10 years? Winn installed CIM for two reasons--to speed just-in-time delivery of stock and custom bottles and to tighten statistical process and quality control (SPC/SQC) for part qualification in an increasingly competitive cosmetic-bottle market.

Winn's production and process monitoring were installed and running by last March. Winn has also greatly upgraded electronic quality-measuring devices and will soon have these hooked into the CIM network as well. Ultimately, Winn's goal is to project orders and manage inventory, automatically, updating for months ahead. For now, its CIM program updates current jobs, but not the next job in line. Future jobs are still entered in a separate computer file.
The "brain" of Winn's CIM network is an IBM (International Business Machines Corporation, Armonk, NY, www.ibm.com) The world's largest computer company. IBM's product lines include the S/390 mainframes (zSeries), AS/400 midrange business systems (iSeries), RS/6000 workstations and servers (pSeries), Intel-based servers (xSeries) RS6000 RISC-type workstation, running Focus 2000 software. The RS6000 acts as a server for nine standard IBM-compatible PCs that can access Focus 2000 screens in various company departments. Focus 2000 runs on a Novell Network A LAN controlled by one of Novell's NetWare operating systems. See NetWare. and is being upgraded to faster, more powerful Windows 3.1 software. That software will cut the computation time In computational complexity theory, computation time is a measure of how many steps are used by some abstract machine in a particular computation. For any given model of abstract machine, the computation time used by that abstract machine is a computational resource which can be required to graph trend charts from 1.5 min to 3 sec. Users also won't have to pause as displays are redrawn while a ripple of new machine data is absorbed.
Monitoring data are collected from six PlantStar M-CIM (manufacturing cell interface module) data-acquisition terminals mounted on pillars in the plant's center aisle between the double row of blow molding machines. The M-CIM terminals gather data from two or three blow molders apiece. Machine packer/operators can enter scrap and downtime reasons on the touchscreens for their machines. On any terminal, a user can call up touchscreen graphic displays of real-time data Real-time data denotes information that is delivered immediately after collection. There is no delay in the timeliness of the information provided.
Some uses of this term confuse it with the term dynamic data. for all the machines.
M-CIMs take their data direct from sensors on the blow molding machines, not via the machines' process controls. This avoids difficulties with the differing levels of sophistication so·phis·ti·cate

2. among machine controls of different ages. M-CIMs monitor six data points at Winn: cycle time, trimming time, barrel temperature, mold cooling-water temperature, blowing-air pressure, and screw rpm. These sensor points are hardwired to the M-CIMs.
Do M-CIM sensor data and the machines' built-in process controls always agree? No, and that's an added safety feature. "It's a way of double checking the accuracy of your sensors," says Winn quality control manager Michael Ramos. Several times already, he says, Winn has detected sensor problems because of such a discrepancy.
To protect stored data in case of power failure, the CIM system is backed up with battery packs at each M-CIM and at the network computer (RS6000) level. Batteries can support the server for 20 min, with automatic shutdown after 15 min. The M-CIM database is maintained up to 30 days under battery power.
CIM is bringing some efficiencies already. Production manager Wayne Whitaker says he sees as much as 15% higher productivity, though some of that improvement may be more apparent than real. As operator/packers learn to use CIM, it makes them more aware of coding a reason for rejecting parts. "They used to reject parts just to catch up in packing," he says. "They're more aware now, and that doesn't happen any more."
