Http:// www.aero-tu-berlin.de/forschung/stroemungsme β technik/sensori K/sensorik.htmlGo up open.Piezoelectric film sensor is made of thin PVDF film, and this PVDF film is metallized in both sides.If power of effect on this film then produces a voltage change of measuring by operational amplifier.
A kind of crash sensor of form of pressure-sensitive lacquer is disclosed by DE 103 17 638 A1.Apply the piezoelectricity lacquer painting (Piezolackfl that some are partly insulated for example can for the front shroud of passenger vehicle
What che), produce evidence so that can produce collision alarm to position at this front shroud.Apply the lacquer of varying sensitivity in a flexible program, can for these zones.
According to DE 36 29 082 A1, below the indicia band on the border, place that is used for the tennis court, the film band with piezoelectric property is loaded in the ground.Just produce a signal when the tennis collision is near indicia band or on the indicia band, whether this tennis of the formal proof of this signal has hit the outside, place.
In the raindrop spectrograph according to DE 295 14 823 U1, piezoelectric membrane uses as the sensor that is used for raindrop.When hitting this film, raindrop produce the proportional potential pulse of the momentum with these raindrop.Can determine diameter and raindrop volume by this potential pulse.Every square metre quantum of rainfall is obtained by the addition of raindrop volume.
Summary of the invention
Task of the present invention is, surveys touching guide plate by means simple and with low cost when conveying single paper.
According to the present invention, a kind of device that is used for conveying single paper by printing machine has been proposed, this device has: a delivery element, this delivery element act on this sheet-fed and this sheet-fed are travelled forward; The guide plate of this sheet-fed that is used to lead; One is used for determining the sensor device of this sheet-fed with respect to the position of this guide plate; And one be used to regulate the executing agency of this sheet-fed with respect to the position of this guide plate, and wherein, at least one tactile sensor element of a face of this guide plate and this sensor device structurally merges.
According to the present invention, a kind of method that is used for conveying single paper by printing machine has also been proposed, wherein, during this sheet-fed travelled forward, its actual range with respect to a guide plate was measured continuously and is compared to set a distance with one, wherein, be formed for the regulated value of an executing agency by these fiducial values, wherein, regulate the position of this sheet-fed, reduce poor between set a distance and the actual range thus by described executing agency.Use a plurality of range sensors that are used for actual range; If this sheet-fed contacts with this guide plate, then produce a signal, according to actual range signal between this signal evaluation (gewichten) sheet-fed and the guide plate, that determine by these range sensors.
Favourable configuration is obtained by other measure.
According to the present invention, the face of a guide plate is equipped with at least one tactile sensor element.Can determine reliably by described sensor element: whether sheet-fed is and at what position contact guide plate.Can regulate an executing agency by means of sensor signal, this executing agency is to this sheet-fed generation effect, and this sheet-fed and sheet-fed subsequently occupy a position with respect to the guide plate expectation thus.
A guide plate face or some guide plate part faces can have the coating of a piezoelectricity, wherein the local segment of this guide plate face electricity ground contacting.This guide plate face and described tactile sensor element constitute a machine assembly.When being provided with a plurality of guide plate part face that respectively has a sensor element, passable is to decide to select these to be ready to use in the sensor element of analyzing and processing on use occasion.The selection of the sensor element that these are active can be undertaken by operating personnel or computer control ground.If some pneumatic actuator units (Aktorikelement) are set, then obtain configuration closely on the space between sensor element and the actuator unit in a guide plate.On a guide plate, can use active (piezoaktiv) lacquer of a kind of piezoelectricity or a kind of coating that constitutes by the active film of piezoelectricity as the tactile sensor element.If touch by sheet-fed and produce a signal on sensor element, then this can cause the variation of machine parameter such as air blowing delivery rate, so that avoid touching in the future.In order to reduce temperature error, the lip-deep temperature of guide plate can be measured continuously and is used when regulating air blowing or air extractor.
When using a plurality of sensor element, advantageously, store and be subjected to time control ground read output signal according to the principle of charge transfer device (Ladungsverschiebeelement).In order to control the flying height of a sheet-fed with respect to guide plate, the tactile sensor element can use with ultrasonic sensor combinedly.For example can regulate the flying height in the antemarginal zone of the sheet-fed that is freely led thus.If for example the distance measurement signals of ultrasonic sensor be in the predetermined scope and tactile sensor indicate rugose sheet-fed and contact with guide plate, then can improve the air blowing speed in the contact area.
