DE102006028158A1 - Positions, levels, areas or objects determining and monitoring method for use in e.g. sheet reversing device, involves flexibly connecting transmitters and receivers with one another - Google Patents

Abstract

The method involves flexibly connecting transmitters (1) and receivers (2) with one another. A signal reception is interrupted besides beam interruption by beam deflection based on the flexibility of the connection. Positions, levels, areas or objects are determined or monitored contactlessly or by contact with an optical combination sensor. Hazardous objects outside of a transceiver area are recognized, and the optical combination is automatically aligned within a defined area.

Description

Method for a peripherally acting position, level and monitoring sensor wherein the positions, levels, rooms or objects to be determined both contactless and by touch are determined and / or monitored, thereby dangerous goods outside the transmitter-receiver area or with appropriate constructive design are detected without touching the sensor, the transmitter and receiver automatically align themselves again after the interruption and the sensor as a mobile unit 5 to 10 may be executed, according to the preamble of claim 1 and claim 2.

When feel medium Both outer components serve as well as from the sender to the receiver emitted light beam, serves as a signal medium called light beam, when the light beam reception is interrupted, a signal is sent to a Control passed.

• – Strahlunterbrechung erfolgt durch Gegenstand zwischen Sender und Empfänger, siehe 5.
• – Strahlablenkung erfolgt durch Veränderung der Sender – Empfänger – Ausrichtung beispielsweise durch verkanten, verdrehen etc., siehe 6, 9 und 10.

Of particular importance is that the light beam reception in different ways - namely by beam interruption or beam deflection - can be prevented:

• - Beam interruption occurs through object between transmitter and receiver, see 5 ,
• - Beam deflection is done by changing the transmitter - receiver - alignment, for example, by tilting, twisting, etc., see 6 . 9 and 10 ,

In which the beam interruption is usually contactless, while the Beam deflection by a circumferentially at a suitable location The force acting on the sensor is caused, depending on the constructive Design with or without touch acts.

In Automation technology often demands simultaneous Position determination, position monitoring, Level determination and level or room monitoring on.

So far For the realization of the mentioned functions several sensors needed mostly is even for each function requires its own sensor technology; at greater distances between transmitter and receiver this is even mandatory.

The Development, production, operation and maintenance of such sensor systems and associated Controls require a lot of effort, already the failure of one Sensors leads often failure of the entire system; These reasons speak against one wider use of automated devices in households and as a tool for disabled people People.

This Invention is therefore the object of an inexpensive, reliable and safely operating sensor unit to imagine by means of many investigative and monitoring tasks can also be realized simultaneously and efficiently.

One Such a sensor not only offers enormous savings potential in the development, production, operation and maintenance but works with big ones Precision, Speed and reliability also over bigger and changing Distances.

This is of particular advantage when used in hazardous machinery, Devices, etc., at higher Temperatures and handling of hazardous substances. Another one Field of application is building automation, for example, the monitoring of doors, Windows etc.

The required properties are using a special sensor technology realized.

Such a sensor consists at least of:
Optosender, Optoempfänger, Elastic transmitter-receiver connection and a signal control, with conveniently commercially available controls can be used.

Show useful embodiments 5 . 6 . 7 . 8th . 9 and 10 ,

5 shows an open sensor with changeable transmitter-receiver distance and elastic connection between transmitter and receiver and light beam interruption by object between transmitter and receiver.

As elastic connecting member here is a spring arm 3 ,

6 shows an open sensor according to 5 with light beam deflection by an external force.

7 shows an open sensor according to 5 wherein the spring arm is designed to realize longer distances as a telescopic arm.

8th shows a closed sensor with light beam deflection and changeable distance and elastic connection between transmitter and receiver and integrated signal control.

As an elastic connection and Tastglied here serves the Tast-Verstell- and protective member 13 and partly the receiver housing 15 ,

9 shows a closed sensor according to 8th with eccentric transmitter-receiver alignment for additional axial pressure determination and with additional axial spring return.

The displacement of the tactile adjustment and protection member produced by the axial compressive force F rotational 13 is by means of the rotary wedges 6 and 7 converted into a transmitter-receiver orientation changing rotational movement and thereby leads to a beam interruption.

10 shows a closed sensor according to 8th wherein the light beam deflection is triggered without contact by approaching two magnetic poles of the same name.

A Advantageous application of this invention will be described below a possible Sensor application described, showing:

1 . 2 . 3 and 4 an application in a sheet turning device, this device is used to page through individual pages stored in a folder.

Of the At the same time, the sensor is the basis of the page turning frame, and thereby transmits its sensor properties partly on the unit thus formed; At the same time, this is also a room-feeler element.

In normal operation, the turning frame becomes out of the home position after the signal has been released from the sensor 1 moved in the reversing position 2 . 3 and 4 , Due to the relatively large sensing distances in this case a laser beam is used as a signal medium and sensing element, this laser beam is as a non-contact light signal from the transmitter 1 to the recipient 2 sent and received in normal operation of this, this signal is used until reaching the turning position 2 initially only for room monitoring for the traversed by the turning frame room A; from the reversing position, this light signal is used in addition to the position determination, concretely, the turning frame is initially set to the height of the two folder sheet holder. The correct dimension is reached when the light beam is interrupted by a folder leaf strap 4 , For sheet recording of the swing frame is then lowered by means of control command to the recording stack out at the same time the room B is monitored 4 ,

The respective sheet recording level is at interruption of the light signal determined by the recording stack, in this position, the Swing frame held to the sheet holder, after the automatic sheet holder is the swing frame with the recorded folder sheet in the each cheapest Filing position moves, and also the Blattablageniveau by interruption the light signal is determined by the discard pile.

With This technique is the sheet loading and storage position of the swing frame automatic adapted for each sheet recording and sheet storage of the existing recording and discard pile height

Subsequently, will the swing frame moves back to its normal position.

To step after activating the sensor disturbances influencing the turning frame, thus the light beam reception is interrupted and the workflow changed by means of control.

From Of particular importance is, as already mentioned, that the light beam reception in different ways - namely through Beam interruption and / or beam deflection - can be prevented.

In order to a beam deflection can be done, are transmitter and receiver as well the suction cup holders are connected by means of an elastic spring arm, which, when a corresponding load occurs, the transmitter - receiver orientation changed so that no light signal is received, which then generated Control signal is used to stop the workflow.

Especially This is advantageous due to the elastic compliance of the sensor holder also over the shutdown position, injuries and damage can be avoided and the spring arm after removal of the disturbance automatically again can take its initial position, both transmitter and receiver as Also, the two suction cup holders do not need to be readjusted.

A Another advantage is the arbitrary adjustability of the transmitter - receiver - distance within the specified range, with the stated properties preserved, with the use of laser light is also omitted also the usual ones Refocusing.

All known optical light barrier systems, etc., such a combination of functions do not suggest.
