DD228490A1 - METHOD FOR COMPUTER-CONTROLLED AUTOMATED CUTTING OF FULL WOOD - Google Patents

Abstract

The invention relates to a method for computer-controlled automated cutting of solid wood. It is the object of the invention to reduce wood losses. The object of the invention is to develop an individual computer-controlled automated cutting method of solid wood. The solid wood is placed in a co-ordinated blanking cycle until the optimal separation is achieved. After determining the shape of the board and the defectoscopy computer-controlled Laengsschnitte preferably take place on one or more successively arranged Kreissaegemaschinen with a fixed and a computer-controlled adjustable idle blade. The blanks and Aufteilreste be discarded, the remaining solid wood is transported after Pasieren the last Saege in the starting position of the blanking cycle. Fig. 1

Description

Title of the invention

Method for computer-controlled automated cutting of solid wood

Field of application of the invention

The invention relates to a method for computer-controlled automated cutting of solid wood such as unedged or edged boards, squared timber, frames, strips and the like, preferably by longitudinal cutting by means of sawing. "

Characteristic of the known technical solutions

Purely the longitudinal section are mainly multi-blade longitudinal-section circular sawing machines used, whereby Sinblatt longitudinal section "circular sawing machines and Besäum-circular sawing machines are used.

Known are microelectronically controlled double seamers and multi-blade circular saws with adjustable in idle

saw blades,

Object of the invention

It is the object of the invention to reduce the accumulated wood losses (remainders) to the objectively possible minimum and

C ; ;. .-I. - U L 1 ί. Η.

To produce blanks with specified dimensions, which have no or only the permissible errors.

In comparison with the "known procedures, the working time is reduced"

Explanation of the essence of the invention

It is the object of the invention to develop an individual computer-controlled automated Susehnittverfahren of solid wood, in which the individual process steps are coordinated with each other so that an optimization of all different blanks to be produced taking into account the defects of the wood, the wood shape, the feasible cutting guides, and the priorities of the individual blanks according to the needs. ·

This object is achieved by the solid wood is repeated after the known destacking and separating repeated until optimal separation into a tailored cutting circuit is given, in which after determining the board shape (measured) and the Defektoskopie computer controlled longitudinal cuts preferably on a circular saw a fixed and an idle computer controlled adjustable sheet are made, the blanks and Aufteilreste discarded, the timber voll-trsnsportiert, the board shape and the defects determined again and entered into the computer, computer-controlled longitudinal sections, preferably on a circular saw with a fixed and a in Idle computer-controlled adjustable sheet are made, the blanks and Aufteilreste discarded and the remaining solid wood is transported to the starting position of the blanking cycle. The values of the determination of the board shape (measured) and the defectoscopy are entered into the calculator. Based on these values as well as the control of the order fulfillment, the calculator calculates the optimal distribution of the solid wood and controls the saws. The cross section of the solid wood takes place outside the blanking cycle.

Aiisführungsbeispiel

The invention will be explained below using an exemplary embodiment.

In the accompanying drawing aeigt

Fig. 1: Representation of a computer-controlled width distribution by two longitudinal cutting circular saws, each with a fixed and an adjustable blade

The board is unstacked and singulated, fed via a buffer store 1 to a shape and dimension determining device 2 and to a defectoscopy device 3. The division coordinates perceived by sensors during the run are used by the computer 4 for the positioning and control of a circular saw 5 a fixed and a computer-controlled adjustable idle «The blanks 6 and the Aufteilreste 7 are discarded after passing through the circular saw 5 by means of computer-controlled baffles 8. Thereafter, an intermediate storage of board sections in a further buffer stock 1 is required «Thereafter, the board of a further shape and dimension determination device 2 and a Defektoskopieeinrichtung 3 is supplied. After appropriate positioning, the board of a second circular saw machine 5 with a fixed and an idle computer controlled adjustable blade augeführt. After separation blanks produced β and / or Aufteilreste 7 by means of computer-controlled baffles 8, still further processed board sections are fed to the circuit again.

Claims (4)
