Automatic edge banding machine KE-396JC for softforming

Purpose

The KE-396JC automatic edge banding machine is designed for banding profiled edges of furniture components and workpieces with synthetic roll-fed materials using the softforming method. The machine supports four profile types.

Machine units

1. Profile milling unit.
2. Pressure roller unit.
3. End trimming unit.
4. Edge overhang trimming unit.
5. Lower scraping unit.
6. Scraping unit with straight blades.
7. Buffing unit.

Main features

• Production of components using the softforming method.
• Support for four softforming profiles.
• Servo-controlled adjustment for different processing profiles.
• Upper glue pot.
• Feed speed 10 m/min.
• The machine can operate 24 hours a day without interruption.
• Industrial computer with a touch screen for controlling the machine functions.
• Integrated position-based control for contactless activation of the processing units.
• Programmable processing pauses.
• A separate frequency inverter for each processing unit.
• Lighting inside the protective enclosure.
• Limit switches on the doors of the protective enclosure.
• The workpiece feed spacing device prevents damage to the machine units during operation.
• A pneumatic guard on the glue application roller protects it from contamination.
• Adjustment of the front and rear edge-band overhangs from the control panel.
• Design in compliance with CE requirements.
• The machine is equipped with two liquid application units:

1. The first unit applies release agent through two nozzles located before the workpiece pre-milling unit. A special release agent prevents protruding adhesive residues from adhering to the workpiece.
2. The second unit applies polishing fluid through two nozzles located before the buffing unit. The cleaning fluid removes the release agent applied at the beginning of the process and any loose adhesive residues. It also adds gloss to the finished edge of the workpiece.

Engineering advantages

The machine is controlled using an industrial PC with a touch-screen interface. The icons for switching units and assemblies on and off are intuitive and require no special skills to operate the machine.

Glue pot heating pauses can be programmed.

The workpiece feed spacing device maintains the minimum distance between workpieces, preventing damage to the machine units during operation.

The workpiece edge profile milling unit is equipped with two milling motors. The cutter height and position are adjusted by servo motors.

The processing profile is changed from the control panel at the touch of a button by servo-controlled adjustment of the profile cutter height relative to the workpiece.

The heating lamp heats the workpiece edge before application of the edge band, improving bonding quality.

The edge-band grooving unit creates a groove on the inner side of the edge band, allowing it to bend during application.

Servo-controlled pressure roller unit switch precisely between processing profiles at the touch of a button. Several heating lamps and a hot-air blower are used to heat and soften the edge band.

Additional upper and lower pressure rollers press the edge band against the workpiece when processing different profiles.

Upper quick-change glue pot for EVA/PUR adhesive with a non-stick coating is installed on the pressure roller unit.

The end trimming unit is equipped with two high-frequency motors. The saw units travel along special linear guides. The unit is equipped with an automatic guide lubrication system.

The edge trimming unit consists of two high-frequency motors equipped with radius cutters for processing edge bands with a thickness of 0.5–0.8 mm. The workpiece is tracked by two large circular copy wheels mounted on a floating unit, one on each motor. This design prevents defects during trimming.

The lower scraping unit removes marks left by other tools and improves the processing quality.

The flat scraping unit is equipped with four straight carbide blades that process the edge band where it meets the workpiece. This operation removes excess adhesive and minor surface irregularities along the glue joints.

The buffing unit polishes the processed section of the edge band. High-quality finishing is achieved by an oscillation system driven by pneumatic cylinders. A polishing-fluid application unit provides the edge band with a final gloss.

The edge banding machine frame is built as a rigid box structure with the necessary reinforcing ribs, ensuring precise positioning of all units throughout the machine's service life.

The encoder on the pressure beam lifting/lowering mechanism automatically positions the beam according to the workpiece thickness set on the control panel.

The centralized lubrication unit automatically lubricates the guides of the end trimming unit.

The electrical components comply with CE requirements.

The machine cabin doors are lined with a layer of polyurethane foam sound insulation, providing comfortable operating conditions.
