Automatic edging system AOP

The AOP Automatic Edging System is designed for the automatic lengthwise plastering of side timber stressing the high performance and load and minimization of operating staff.

The timber is moved to the equipment through a system of side timber gathering transversal chain conveyors and a side timber separator. The insertion, setting, cutting and shifting of plastered planks is automatic, and the operating staff supervise the running, and carries out the qualitative sorting and reduction. The entire equipment is mounted on a supporting steel structure, conveyors for collecting and removing waste are installed in the space under the equipment.

Among the main operations carried out by the automatic plastering system are:

  • Sorting of timber before plastering (exclusion of flawed parts)

  • Direction of the timber with the bulge upwards

  • Cutting away the flaws on the far end of the timber

  • Capping the timber – cutting away the flaws (of the tongue) at the nearest end

  • Measuring the width of the timber, processing the measured data - optimization

  • Operating signals for the centering conveyor, and managing the positioning (turning) of the part before plastering (as requested)

  • Control of the plastering saw – optimizing the manufactured widths with respect to the max. load

  • Actual timber plastering

  • Removal of cuttings behind the plastering saw

  • Control signals for sorting the plastered timber for sorting side timber – as requested depending on the specific execution of the sorting conveyor

The actual plastering saw is standardly equipped with a pair of mobile saw cases (A, B) and a pair of separating wedges (C, D).

The machine is approved by the State Testing Institute and fully complies with current EU regulations.

Case A (on the door side)

for 1 saw disc

Case B (on the drive side)

more saw discs – usable width 128 mm

Separating wedges

Wedge C
(on the drive side)

convertible together with case A (position of the wedge firmly fixed to the position of the saw disc)

Wedge D
(on the drive side)

convertible irrespective of the movement of case B (separately convertible against the outer or inner saw disc in the saw set of case B – depending on the cutting method)

Execution:

  • frame – tough weldment from quality steel profiles and sheet metal

  • shift – four bottom driven cylinders, two top driven pressure cylinders, converting hydraulic cylinder height, speed of shift driven by the frequency convertor

  • spindle – placed in five (4+1) high-tolerable ball-bearings, spindle driven through wedge belts

  • conversion of mobile saw cases A, B + separating wedge D – through the hydraulic service cylinders + linear position scanner, position control through control software
