Drive System Retrofit for MasterDrives

Because of their superior functionality, comprehensive performance range and application flexibility, the Siemens Simovert MASTERDRIVES in CUVC, CUMC, Compact form and other variants has been a very successful drive system for single motor and multi-motor applications. The established common DC bus system enabled it to be used on demanding production machine processes across a wide range of industry sectors.

All good things must come to an end, but that doesn’t mean the end of the line for your production machine.

Optima’s innovative approach to upgrades significantly reduces the installation time and minimises risk to your site. All of our systems are thoroughly tested before they are shipped to site, completely eliminating any “out of box” failures.

Some of the benefits you will realise are:

  • Extended life span of your machine and increased availability due to continued spare parts supply with full support by Siemens
  • Improved productivity through lower energy costs and faster production cycles, through:
    • Simple operation monitoring using operator panel

Don’t replace old for old. Replace old for new at a similar cost (including conversion)

When faced with the complete failure of a HMI TP177A, our customer wished to source an equivalent part from the original supplier.

Two problems were:

1) The obsolete screen was programmed with an obsolete package – Protool

2) The cost of the old replacement screen was more expensive than a newer and fully supported HMI.

After analysing the upgrade possibilities Optima were able to solve the two problems of replacement and obsolescence but with a further advantage to the customer.

Optima were able to convert the old HMI configuration to the new HMI equivalent and supply it to the customer for around the same price as the obsolete part.

It is often the case that upgrading hardware can actually work out less in real cost terms than replacing old parts  on a like-for-like basis.

Weekend shutdown sees pump system upgraded to latest Siemens Sinamics drives and S7-1200 PLC

When faced with the unreliability and ageing Crabtree motor starter sets, a leading manufacturer of waterproofing products turned to Optima for assistance. The existing pump control system was direct on-line and required pump changeovers to be initiated manually.

Old Pump Control Starter Panels

The solution was to replace the existing starter panels with a single panel housing 18.5kW and 30kW variable speed drives with a S7-1200 PLC controlling pump changeover from a 4 inch Basic HMI. This display shows providing pump status, hour run and pump selection buttons and also allows the system to run in fully Automatic or Manual modes.

New Pump Control Panel In-Situ

The installation task had to be completed during a weekend shutdown, requiring careful coordination between production and our engineering team to schedule the works.

The system was powered up ready to run in full production before Monday’s switch-on.

Improved Performance And Reliability Following Upgrade From Hydraulic Motors To AC Geared Motors

When a major paper producer was faced with increasingly temperamental performance from the existing hydraulic drive control system on their Valmet KL Winder, they turned to Optima for assistance. The system suffered from uncontrolled starting from cold until the hydraulics had reached normal temperature. However, even at normal operating temperature, there were still issues with tension control being unpredictable.

Optima were asked to suggest possible upgrade solutions for the winder. Our solution was to use a Siemens Sinamics drive system, controlled from our own custom-written winder blocks. Optima’s winder blocks are PLC-based and provide all the functionality required of any winding application.

The new drive system was specifically designed to suit the exact material tensions, roll diameters and operating speeds of the winder to ensure both performance and cost needs were met. The actual products run on winders sometimes differ from the manufacturers own design.

A complete new control suite was built to house the new PLC and drive hardware. Installation was managed by Optima.

Final Commissioning was carried out by our own engineers specialising in web transport systems.

Tuning of the fully-compensated system was carried out over a series of product trials on different grades of paper. The drive control system is complex, not just for accurate tension control but also to drive either end of the paper unwind with separate AC geared motors – not an easy task to achieve. Optima’s control algorithms ensure that control of the unwind reel is shared equally between each drive whilst also preventing ‘slippage’ of the driving mandrel within the unwind core.

Optima will be pleased to provide a no-obligation site visit to discuss how we might improve the performance of your existing winder or for a completely new upgrade.

Optima’s upgrade solution for a Sirpak 200 cut-to-length Machine system reduces waste by 9km per week

Optima were approached by an internationally renowned packaging manufacturer, particularly specialised in cartons, labels and leaflets. The company’s manufacturing facilities across the globe must deliver maximum efficiency and reliability to enable excellent customer service and innovative packaging designs.

Their Scotland-based plant was faced with obsolescence and unreliability of a Sirpak 200 tube forming and cut to length machine. The linear tube-forming line on site is used for the production of all-shape composite cans. It allows the manufacturer to produce odd-shape packaging for premium brands such as Chivas Regal and Glenfiddich. Customers in this sector demand high-quality materials and unique packaging designs. If their supplier is unable to produce these up to standard and on time, it would be losing significant amounts of revenue. This is where Optima got involved to provide a stand-alone registration system to replace the existing cut-to-length equipmentSirpak 200 Linear Tube Forming Machine.

The new system that Optima developed incorporated a fully integrated Siemens platform with Simotion Drive equipment, Simatic PLC and a Siemens Synchronous Motor gearbox combination.

New features for the machine – a Sirpak 200 – included a recipe interface for the different packaging tube lengths produced on the machine. To minimise downtime at change-over from the old equipment to new, Optima installed a new panel, encoder and PEC next to the existing units without interfering with the existing control system. Because of this, the project commissioning was completed in 5 days without problems or delays.

Of greatest benefit to the customer is the reduction in waste that was achieved following the upgrade. Michael Hill, Managing Director at Optima, explained the future benefits further: “The current system was sheet-fed, which means there is unprinted material (3’’) between each repeat length. Following detailed consultation with the customer, Optima’s control system facilitated the use of printed rolls instead of sheets, thus eliminating the requirement for unprinted sections. With 3″ saved on every 40″ of material, the new system would facilitate a 7.5% reduction in product waste. As the company produces thousands of metres of carton per week (approximately 40 metres/minute for 10 hours per day, 5 days per week equating to 120,000 metres) the savings equate to 9km of less waste every week.”
