Purpose

Automatic edge banding machine KE-399 is designed for simultaneous banding of straight edges of furniture boards and blanks with synthetic roll material. The machine allows you to get a product with three different options for gluing the edge.

Main features

• Feed speed 15-24 m/min for straight parts, 15-18 m/min for beveled parts;
• Control panel "Touch screen";
• Feed line with heating (not installed on machines with milling);
• Built-in waypoint control for contactless control of processing units;
• Possibility of programming technological breaks;
• Individual frequency converter for each working node;
• Lighting in the protective cabin;
• Limit switches on the doors in the protective cabin;
• Pneumatic shutter on the glue roller, prevents it from getting dirty;
• Adjustment of the front and rear overhangs of the edge from the control panel;
• Execution according to CE standards.
• The machine has two units for applying liquids:

1. The first unit for applying the separating liquid: with the help of 2 nozzles in front of the pre-milling unit (milling) of the workpiece. This is done by applying a special separating liquid, so that the glue residues that come out do not come into contact with the workpiece.
2. The second unit for applying polishing liquid: using 2 nozzles in front of the polishing unit. This is a cleaning fluid. The main task is to remove the anti-adhesive applied at the beginning (separating liquid) and free adhesive residues. And also to give shine to the finished edge of the part.

Engineering advantages

The bed of the edge banding machine has the form of a rigid box with the necessary stiffening ribs, which guarantees the exact location of all nodes during the entire period of operation.

The machine is controlled using a special remote control equipped with an industrial display with a “Touch screen” system. The on/off icons of units and assemblies on the display are intuitive and do not require special skills to operate the machine.

Possibility of programming technological interruptions of glue bath heating.

Unit for pre-milling the end of the part before gluing the edge onto the formed surface. It is equipped with two motors that carry out the processing of a straight and inclined section. It has digital displays to adjust and display the angle of inclination.

The machine has two clamping units. Each pressure unit consists of 5 rollers, which are driven pneumatically, which guarantees an even distribution of forces on the edge during gluing. The rollers have different cones, which ensures the distribution of the pressing force across the thickness of the part. The powerful pneumatic cylinder of the pre-cut knife successfully copes with thick edges.

The machine is equipped with two glue baths with a glue dispensing mechanism - one for straight parts, and the second for parts at an angle of 45°. The pre-cutting unit for edge material cuts the edge fed from the roll using a guillotine knife. The press group provides the necessary pressure on the edge material.

The end trimming unit is equipped with two high-frequency electric motors, and the movement of the saw units is carried out along special linear guides. The unit is equipped with an automatic lubrication system for the guides.

The milling unit consists of two high-frequency electric motors equipped with radius cutters, which allow processing edge material with a thickness of 0.4 - 3.0 mm. The part is tracked by two large round cams (on each motor) mounted on a floating assembly, this design prevents scrap during milling. The machine is equipped with two pairs of milling units - 2 roughing units and 2 units for fine milling of overhangs.

The rounding (contouring) unit is equipped with two high-speed motors and operates successfully at a speed of 18 m/min. There are four possible operation schemes for the unit.

The first and second scraping units are equipped with two carbide radius knives, which, after milling the edge, remove a thin layer from the milled part of the edge and remove the kinematic wave, as a result we get a smooth processed surface. At the first node the knife radius is 2 mm, at the second node the knife radius is 1 mm. The units are switched on from the machine control panel. The scraping units are equipped with mechanisms for pneumatic adjustment from a remote control to a different thickness of edge and a mechanism for dividing the remaining edge along the length for more efficient removal.

The direct scraping unit is equipped with two hard-alloy straight knives (adhesive scraper), which carry out edge processing at the joints with the part. This operation removes excess glue and micro-roughness on the seams in the places where the edge is glued to the part.

A double polishing unit polishes the processed part of the edge; high quality is achieved through an oscillation system driven by pneumatic cylinders. To impart a final shine to the edge, a unit for applying polishing liquid is installed.

The pressure band instead of rollers guarantees precise and reliable positioning of the workpiece in all stages of edging.

The mechanism for lifting/lowering the clamping traverse is equipped with an electric drive, which ensures fast and accurate installation to the required thickness of the part.

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

The electrical components are made in accordance with CE standards.

The doors of the machine cabin are sheathed with a layer of sound insulation made from foamed polyurethane foam, which allows you to achieve comfortable work with the equipment.
