Abstract

The invention relates to a metering device paper cutter saddle. It is essential forward and reverse the two counters connected to the seat position sensor a via a switch, preferably a multiplexer, k imaging, while choosing one of the counters are displayed on the display absolute saddle position and choosing the second one from the counters the display shows the width of cut paper. The device can be advantageously provided use paper cutters for construction but also in other facilities in which it is need to measure the position.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for measuring a seat of a paper cutter comprising a seat position sensor resiliently coupled to a movement screw of a seat drive, wherein the output of the seat position sensor is connected to an input circuit input.

Measurement of the paper cutter seat is currently performed on cheaper cutters by epiprojection or slide projection. For more expensive cutters, digital measuring is used _; either incremental or absolute. The device for incremental measuring of the paper cutter saddle must be calibrated after switching on, which is done by passing the saddle over the reference point. The absolute gauge of the paper cutter seat is calibrated automatically as soon as it is switched on.

The disadvantages of the prior art are in the epiprojection, slide projection and incremental metering device of the paper cutter seat, in particular in that it indicates the distance of the seat from the knife and not the size of the paper being cut. Thus, when approaching the next coordinate, the operator must subtract the desired paper size from the previous coordinate, which entails the risk of errors and is particularly laborious when cutting strips. The disadvantage of the device for the absolute measurement of the paper cutter seat is, in particular, its cost.

To a large extent, the paper cutter saddle metering device formed by the saddle position sensor resiliently connected to the saddle drive movement screw, wherein the saddle position sensor output is connected to an input circuit input according to the invention, is that the input circuit output is connected to the first input of the first counter and to the first input

252 261 second counter, the first counter is connected with its outputs to the first switch inputs and its second input to the manual reset button output with the auto reset button output, and the third switch input to its output to the display input, its fourth input to the normal mode button and with the second input of the second counter and its second inputs with the outputs of the second counter.

The advantages of the paper cutter saddle measuring device according to the invention are, in particular, in that, due to its simplicity and low production costs, it allows both direct reading of the cut paper size and the distance of the saddle from the knife, i.e. the total paper size remaining for further cutting. Another advantage is the energy efficiency of the device.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail with reference to the accompanying drawing, in which: FIG.

An exemplary embodiment of a paper cutter seat metering device according to the invention is shown in the attached figure. Here, the saddle position sensor 1 is connected by its output to an input circuit input 2, which is connected to the first input of the first counter 2 ^{and 8 by the} first input of the second counter 4. The first counter 2 is connected, its outputs to the first inputs of the switch 2 ^and its second the manual reset button 6 output, the automatic reset button 2 output, and the third switch 2 input. · The switch 2 is connected with its output to the display 8 input, its fourth normal mode button 2 input and the second counter 4 input and its second inputs with outputs of the second counter 4.

In operation of the metering device of the paper cutter according to the invention, the sensor 1 signals the position of the seat. This signal is adjusted in the input circuit 2 for further processing and applied to the first input of the first counter 4 and to the first input of the second counter 4. As the saddle moves to the knife, the output of the first counter 4 increases while the output of the second counter 4 decreases. The switch J5, which is preferably a multiplexer, transmits a signal from the first counter 3 to the input of the display 8 when the manual reset mode is preselected by the manual reset button 6 or the automatic reset mode by the automatic reset button 2.

If the normal mode is preset by the normal mode button 8, the switch 2 ^{at the} input of the display 8 passes the signal from the second counter 4. At the same time, pressing the normal mode button 2 can obtain information on the absolute position of the seat relative to the knife.

The device according to the invention can be advantageously used in the construction of paper cutters, but also in other devices in which positioning is required.
