VH-1870

The VH-1870 is a vertical heat platen orientation, hydraulic motion controlled hot plate welding system capable of welding parts up to 18” x 70” (457mm x 1778mm) or multiple smaller parts.  Customized variants of this model are available.

When compared to horizontal platen systems, vertical systems typically:  

• allow faster tooling changeovers
• allow ergonomically easier and more positive operator loading and unloading of the tooling
• ensure more precise part half alignment during welding (less scrap) as no special part-part alignment features must be designed into the parts themselves (required for accurate machine pick-up of one part half on horizontal systems)  

This vertical systems twin motion (left and right) tool mounting platens allows independent control of force/speed on each part half, both against heat platen when in melt phase and against each other in weld phase.

Standard Features:

Ultra-Rigid Construction utilizing tubular steel framework with leveling feet and linear guide shafts/bearings designed for precise tool alignment through decades of use.  

7.5 HP, 1750 RPM, 11.0 GPM (5.6kW, 1750 RPM, 41.6 LPM) 1000 PSI (68 Bar) Maximum Pressure Hydraulic System with Proportional Valve Control and Linear Position Transducers offers improved control and reduced machine and coating wear by user programmed variable tool mounting platen and heat platen carriage pressures and speeds including “soft-touch” contact of parts halves to heat platen (Melt) and each other (Weld/Seal).

Digital Four-Zone Temperature Control via PLC with Heater Burnout Alarm ensures even heating and precise temperature control with temperature alarm limits. Burnout alarm halts operation of the machine in the event of platen heater failure.

Programmable Automatic Machine and Heat Platen Startup (Time/Date Based) saves production time as the machine can be user programmed to automatically initialize warm-up of heat platen and hydraulic system before start of production.

Allen Bradley SLC-503 Programmable Logic Controller (other controllers quoted upon request)

Allen Bradley PanelView Plus 600 Touch-Screen User Interface simplifies parameter input and allows the following to be displayed:

• Melt, Weld (Seal) & Open Time Digital Control & Display
• Individual Melt & Weld (Seal) Pressure & Speed Settings
• Digital Temperature Control Settings & Alarm Limits
• Resettable Parts Counter
• Non-Resettable Total Machine Cycle Counter
• Diagnostic Display

Multi-Level Passcode Protection limits parameter adjustment to qualified personnel only.

5 Weld Program/Setup Memory allows storage for instant recall, minimizing tool change time.

External 120VAC Duplex Electrical Outlet allows user to easily connect small auxiliary equipment such as computers, printers, radios, etc.

Dual 1.0 HP, 1725 RPM, 25.0 in/Hg (Dual 0.75kW, 1725 RPM, 63.5cm/Hg) High Capacity Vacuum Pump System designed to secure even the largest parts within the tooling.  Eliminates the need for separate venturi-vacuum systems for each tool.   

Pneumatic Power Sliding Safety Door with Zero Force Cycle Activation Switch and Door Safety Tapeswitch provides optimum personnel protection while reducing operator fatigue.  

Hinged Access Panels with Safety Interlock Switches allows extensive access while providing maximum personnel protection.

Vent Hood with Exhaust Fan evacuates airborne smoke and particulate from the operator location when welding at high temperatures without coatings.  

Interior Viewing Lights enhance visibility of the welding process for the operator.

Two English Language Manuals provides detailed documentation and instruction of installation, operation, setup, maintenance & troubleshooting procedures.

Sequence of Operation:

1. Operator loads part halves into holding fixtures.

2. Operator initiates cycle activation switch.

3. Safety door closes.

4. Part halves are automatically held with vacuum or mechanical grippers.

5. Heat platen advances between part halves.

6. Holding fixtures apply part halves to heat platen.

7. Holding fixtures retract from heat platen.

8. Heat platen retracts.

9. Holding fixtures apply part halves together, welding parts together.

10. One holding fixture releases its clamping mechanism.

11. Holding fixtures open, retaining welded part(s) in one fixture.

12. Safety door opens.

13. Operator unloads welded part(s).
