DE102004037268A1 - Elongated wood or timber unit measuring procedure, involves measuring timber unit in passage in contact-less manner with measuring device that measures progression of side that turns away from stopper - Google Patents

Abstract

The procedure involves measuring a timber unit (2) in a passage in a contact-less manner with a measuring device (4) that measures progression of a side that turns away from a stopper (3). The timber unit has a concave side (2.1) against the stopper that rests against the turning away side. The timber unit is moved relative to the measuring device along the stopper. The stopper forms a vertical contact surface for the timber unit. An independent claim is also included for a device for measuring an elongated wood or timber unit.

Description

The The invention relates to a method according to the preamble of the patent claim 1 and to a device according to the preamble Claim 7.

task The invention is to show a method, with the woods or Wooden elements, especially damaged wooden elements, the one further processing become fast and reliable can be measured For example, to generate measurement data for controlling a woodworking machine or plant, for example a planing plant.

to solution This object is a method according to the claim 1 formed. An apparatus for carrying out the method is the subject of claim 7.

With the method according to the invention the measurement of the timber elements is done in a continuous process and in particular in a cycle or cycle time, the cycle time the usual electronic control (SpS) of woodworking machines, for example Planing plants corresponds.

at the measurement becomes the dimensions or the dimension of the respective wooden element determined in the axis perpendicular to the stop, u.a. at the forward and rearward in the direction of passage and preferably continuously on the intervening length, so then with these Measuring results, for example, a planing machine for optimum chip removal can be controlled automatically.

The invention Measurement method is not only suitable for warped wood elements, but also for damaged Wooden elements, i. with the respective measuring device will also damage and their depth detected and corresponding readings, for example for controlling the further processing machine (for example planing machine) provided.

The Invention will be described below with reference to the figures of embodiments explained in more detail. It demonstrate:

1 and 2 in a simplified representation in plan view and in side view measuring arrangements according to the invention for measuring wood or wood elements.

The in the 1 generally with 1 designated device is used for measuring elongated warped and damaged wood or wood elements 2 and in particular to determine the curvature and damage and their depth in the woods or wooden elements 2 , The device consists essentially of a transport path on which in the illustrated embodiment beam or strip-like wooden elements 2 be moved in a conveying direction A, in such a way that the wood elements 2 are oriented with their longitudinal extent in each case in this conveying direction.

In the presentation of 1 is on one side of the conveyor line a lateral stop 3 provided against the warped wood elements 2 with its concavely curved longitudinal side 2.1 (Hollow side) abut. Opposite the stop is a measuring device 4 provided in the passage constantly the distance to the respective wooden element 2 and thus the course of the attack 3 opposite side of the wood element 2 measures, including at the two ends 2.2 and 2.3 as well as between these ends.

The measured values of the measuring device 4 are connected to an electronic evaluation system 5 , for example, forwarded to a computer, then from these measurements, for example, for example, the curvature of the respective wooden element 2 determined and / or measurement or control data to a processing machine, such as planing machine or its control for optimal setting of this machine and for optimal chip removal supplies.

With 2.4 Damage is denoted that the respective wooden element 2 for example, on the hollow side 2.1 has opposite side. These damages and their depth are with the measuring device 4 recorded in a continuous process and then, for example, as corresponding measured values from the evaluation electronics 5 to the machine control 6 for an optimal adjustment of the processing machine, such as planing continued.

The 2 shows an arrangement or device 1a in which the warped wooden elements to be measured 2 with its concave side 2.1 on a stop forming a horizontal plane surface 3a are arranged and provided with the above this stop measuring device 4a the the stop 3a opposite top of the wood elements 2 is measured in the passage, in the illustrated embodiment, in turn, the respective height at its two ends 2.2 and 2.3 as well as on the length between these two ends.

Basically there is also the possibility to use both methods of 1 and 2 in a mess route, ie the respective wood 2 both side and top to measure in the flow.

The The invention has been described above with reference to an exemplary embodiment. It is understood that numerous changes and modifications are possible, without thereby leaving the idea underlying the invention becomes.
