Description

"Universal high-speed measuring device".

I hereby apply for a patent to be granted, alternatively one Utility model for the invention described below.

In a known measuring device, a so-called measuring drum, the a built-in steel spring keeps a rope under tension, which is connected to the free End is attached to the cutting disk support, related to its movements a drag pointer on a dial with graduations to be transferred by means Knurled screw fixable drag pointer is used to adjust the width on the dial.

The invention for which a patent is pending here also makes use of one Steel cable, as is known, to measure the movements of a movable saw table or cutting disc support on a measuring scale. In contrast to the However, this rope is not kept in tension by a spring, but rather by a known system it coils on the sheave without the action of spring force against two fixed points away.

This spring-less pulley drive has the following advantages: l.) Uniform rope tension in the entire measuring range, resulting in increased accuracy.

2.) Breakage of the spring under extreme load excluded, as this Construction detail not present at all.

3. #) Unlimited measuring range, since the rope is at least theoretically unlimited can be long.

4.) Increased reliability # against what. the uneven rope tension when measuring with spring force can bring differences with larger measuring widths, what is absolutely excluded in the present invention.

Patent application Universal-Sc) inellmeßgerätv.G, Gresser Würzburg Die Dimension adjustment does not take place here as in the previously known system by a such rotatable and lockable drag pointer mounted on the axis, but in that the entire dial is detached from the pulley and opposite is rotated to the required level using a dial.

Then the dial is tightened again by tightening the handwheel coupled to the pulley and each cutting disk movement to be measured is transferred Transfer the steel cable to the pulley and to the dial that rotates with it Other differences to the previously known system are, for example: Universal Can be used for any type of sawing machine, suitable for both SuT) port and Also for table and bridge measurements. Every universal high-speed measuring device can be simple and can be quickly converted for any purpose, i.e. for single, double, or Multiple support or Bridge measurement.

The scale disc can be converted with different scale engravings given (types, -and manufacturing simplification) also both horizontal, -als A vertical view of the device is also possible for the machine operator.

Attachment of the SchnellmeßgerEtes in horizontal, vertical and any way An inclined position is possible, which makes it easier to attach, even if there is not enough space works with almost no wear and tear and is absolutely insensitive to water and dust. # he scale ensures good readability and is break-proof and impact-proof.

The high-speed measuring device is in the immediate vicinity of the control station mounted on the machine to allow exact observation of the measuring scale at the same time To enable operation of the sawing machine. on the material plate lying on the saw table is done in the usual way (without any measurement adjustment). While this cut is in progress, the required width of the next cut (material width) on the scale of the high-speed measuring device set # t. After finishing the trimming table cut, the cutting disc motor needs and the cooling water not to be turned off, but the cutting wheel carrier (or the movable table or the # above saw bridge) can immediately be used for the following The measuring device shows this movement exactly now happens until the desired width is displayed on the measuring scale and now the next cut is carried out immediately without further interruption of the workflow executed.

The width of the saw blade cut is also taken into account from the zero pointer, so does not need to be added to the material width by the saw or to be set separately.

Basically, the saw does not have to start from the zero point when setting the dimensions the scale division, but rather from the zero pointer on the scale The pointer becomes the zero of the scale division to the left of the cutting width of the saw blade (e.g. 4 mm) It only needs to be set once and Patent application 11Universal-Schnellmeßgerät "v.G.Gresser Würzburg later only when changing the Saw blade or a certain amount of wear and tear -checked and from time to time readjusted if necessary.

The actual material width setting or measurement takes place as follows: While the first cut is running, the saw loosens the handwheel and brings it up the zero point by turning the dial with the fixed point pointer to Then he couples the dial with the pulley again by tightening it When this cut is complete, the cutting disc or the saw table or the bridge moved immediately.

This movement shows the scale by turning it against the indicator When the desired material width (e.g. 40 cm) is reached, the cutting disc shift stopped and the next cut is carried out immediately. The following material widths are set in the same way. If the material plate is processed from the other side (the cutting disc is in the opposite direction instead of from right to left is moved, i.e. from left to right \ is the setting of the width dimension to be handled slightly differently.

The dial must then be turned in such a way that the indicator is not is on the zero pointer, but also measured the desired width on the scale the fixed pointer is brought into line with the movement of the cutting disk carrier The dial then rotates until the zero pointer turns into a fixed pointer This has reached the desired width and the following cut can be carried out. This other setting is therefore necessary for this the preset saw blade cutting width is also taken into account.
