Clutch/Brake Controls and Automation Centers

The OmniLink 5000 Press and Automation Control brings a new dimension to mechanical power press production systems – the dimension of affordable total integrated process control through intelligent, microprocessor based technology designed to increase productivity, safety, parts quality, production information, and machine and tooling uptime. The OmniLink 5000 construction is modular, allowing optional hardware for various instrumentation and control functions to be inserted in the controller rack. It is designed to be mounted in the same enclosure that houses motor controls and other electrical controls. The OmniLink 5000 controller can provide the needed flexibility to gain stamping process advantages for manually fed pressews, automaically fed press systems, and presses integrated into production cells.

The following functions can be provided by the OmniLink 5000:

  • Clutch/Brake Control
  • Programmable Limit Switch for sequencing press auxiliary systems and automation
  • Press Auxiliary Systems Control
  • Automation Interfacing and Monitoring
  • Die Protection/Process Monitoring
  • Signature and Tonnage Monitoring
  • Job Storage for 500 production setups with the new OmniLink II color OIT. (unlimited with LinkNet network system).
  • Automatic Setup of Counterbalance, Die Cushions, and Shut Height.The OmniLink 5000 provides clutch/brake logic and control interface logic for auxiliary press system (i.e., hydraulic overloads, flywheel brakes, variable speed controls for press flywheel/stroking speed, lube systems, etc.). Also easily configured for multiple operator stations, and for a variety of dual air valves.

At LINK, we know that unscheduled “downtime” is simply unacceptable. The OmniLink 5000 offers a level of diagnostics and troubleshooting previously unseen in the metalforming industry. When and if problems occur, we have designed the OmniLink 5000 to help you get your production process up and going as quickly as possible. The reason for last stop, and present running status are clearly displayed on the OIT screen. Error messages are in clear English language (or Spanish) as opposed to error codes that must be deciphered. User definable inputs are provided for Top Stop, Cycle Stop, and Master Stop so that if a stop condition exists at one of these inputs, a message of your choice is displayed.

Standard Stroking Modes:

  • Inch
  • Timed Inch
  • Single Stroke
  • Continuous

Optional Stroking Modes (easily configured)

  • Bar
  • Automatic Single Stroke
  • Continous on Demand
  • Operator Maintained Continuous

Dual Stop Time (Brake) Monitor Clutch Engagement Monitor. Displays stopping time limits and actual stopping time limits on operator screen, and prevents successive strokes in the event of an over limit stopping time.
Figure 2 (click to enlarge)

Complies with all OSHA and ANSI construction and functional requirements. Control reliability is accomplished via two separately powered microprocessor systems performing independently and cross-checking each other. If either systems fails, the control will issue a stop signal and prevent successive strokes of the press until the failure is corrected. All critical clutch/brake logic is stored in eprom memory.

Tonnage Monitor and Die Protection Sensor Interface

The System 1100 is a microprocessor-based monitor that can determine, display and compare developed forces with preset limits for machines that use large forces in the production process. Utilizing strain gage transducers located on appropriate load bearing machine components, the System 1100 is able to measure and display both total load and load distribution.  The measured forces are compared with adjustable high, low, and reverse setpoint limits for each strain gage transducer channel.  An out-of-limit stroke will trip an alarm circuit that sends a stop signal to the machine control.

Remote Extensions

Black Max remote segments are housed in separate enclosures from the main Black Max units.  They can be used to create “L” shaped or other sensing field configurations when combined with the main transmitter and receiver units.  Remote segments are extremely helpful when the safety distance requirements place the primary sensing field out far enough so as to allow a person to stand between the light and the hazard.  The remote section will detect that person standing inside the sensing field.  The remote sensors are on a 3″ beam center, and are not to be used as your primary sensing field.  Remote extensions for horizontal guarding are available from 6″ to 51″.

LinkNet puts your whole stamping operation
at your fingertips.

The LinkNet system is a software product designed to be used with standard personal computers running Microsoft operating systems.  LinkNet will allow the OmniLink 5000 Press and Automation Controller, the Microlink and the System 1100 Tonnage Monitor to report information and status back to the PC for display, storage, and printing.  This network enables the use of down time codes (DTC’s for each machine).  In addition, LinkNet incorporates a Preventative Maintenance Module for scheduling and generating work order reports for routine press maintenance.

All data is stored in industry standard Microsoft Access database files.  This allows data to be used with many common spreadsheets, databases, and word processors that can read this format.  Crystal Reports is used to generate reports for the LinkNet System. The data can then be used to create custom reports, charts, etc. to fit the specific requirements of a given situation.

Below are samples of two of the reports that can be generated by LinkNet.

(Left-side Fig) shows a typical tonnage signature graph.  The High peak setpoint, low peak setpoint, and reverse tonnage setpoint limits are shown graphically, along with the tonnage at the cursor position.  An archived signature representing a known “good” part can be overlaid with any other graph to give a quick visual indication of die wear.

(Left-side Fig) shows a section of a report giving lifetime tonnage alarms (by die), which can be used to help determine how a particular die is being utilized in production.

In order to better understand the level of information available to you with LinkNet you may download some typical LinkNet reports in Adobe Acrobat format.

Some of the information available in LinkNet:

  • Average tonnage (for 5000 and 1100 tonnage monitors) collected in 10 minute intervals are stored in shift files.
  • Production rates collected in 10 minute intervals are stored in shift files.
  • DTC information is stored in shift files.
  • Status (low, reverse setpoints On of Off, Bypass mode, etc.) is store in shift files.
  • Lifetime average tonnage and number of strokes is stored by machine and die.  This information can be helpful in determining when rework is due.
  • Lifetime DTC information is stored by machine and by die.  The percentage uptime and downtime can be used to determine where improvements should be made.
  • Lifetime highest tonnage is stored by machine and by die. .
  • Number of high alarms, low alarms, and reverse alarms stored by die.
  • Number of machine rating alarms store by machine
  • Parts, Batch, and Quality counter status can be displayed for each machine
  • Preventative maintenance scheduling allows for organized and timely service and maintenance procedures, decreasing the likelihood of unscheduled downtime..

LinkNet also augments on-board job storage capacity of the units it communicates with, allowing an almost unlimited number of jobs to be stored and recalled over the network.
