DE2622532A1 - Postal tube system slug arrangement - used for testing purposes with buzzer for easy location from outside - Google Patents

Abstract

The slug is for use in a postal tube system as a test slug. It either emits a signal detectable from outside with or without the aid of auxiliary equipment, or is so designed that it can be located from outside. The design allows the position of any jam to be rapidly located. In its simplest form the slug can have a battery-operated siren or buzzer audible from outside, or it can incorporate a radio or ultrasonic transmitter. A further alternative is to make it so that it can be located by a metal detector.

Description

Pneumatic tube socket for pneumatic tube systems

The invention relates to a pneumatic tube carrier for pneumatic tube systems.

In the operation of pneumatic tube systems there are occasional disruptions, if there is a pneumatic tube in the system, e.g. as a result of damage to the pipeline gets stuck. Eliminating these faults is relatively difficult and especially paying because it is not possible to locate the location of the disruption without isolating it Identify search measures, e.g. by sawing open the pipeline. Even if Test closures are provided on the pipeline at certain intervals, can only the location of the fault is limited by opening the test seals in sections a search for damage to the pipeline must then still be carried out will.

The invention is based on the object of taking measures to to be able to determine the location of a fault quickly without delimiting search work.

The object is achieved according to the invention in that a Pneumatic mail box is designed as a test box, which ntwed a from outside the Pneumatic tube system with or without aids emits a detectable signal or the such is designed that it can be located from outside the pneumatic tube system.

In the simplest application, the test socket can be equipped with a siren or provided with another device that emits acoustically perceptible signals be. In the event of a malfunction in the pneumatic tube system, the test socket is sent. At the point of failure, the test socket is then inevitably stopped and as a result the acoustic signal output, the exact location of the disturbance can easily be determined.

Instead of an acoustically perceptible signal emitting device can In the test socket there is also a transmitter emitting radio waves, heat rays or Ultrasonic waves emitting device may be provided, so that the emitted in this way Signals with an appropriate receiver when walking down the pipeline can be caught and the type of disturbance can be quickly determined.

If necessary, the test socket can also be designed in such a way that it can be located from outside the pipeline, e.g. with the help of a metal detector.

The drawing shows a test socket with a built-in siren in one Embodiment can be seen.

In the test sleeve 1, which is designed like an ordinary pneumatic tube there is a siren 2 operated by a battery carried on board In case of a necessary search for a blockage in the pipeline system or after a leak, the siren 2 is put into operation and the test socket in the pneumatic tube introduced and sent. The test socket 1 remains at the point of failure and by the sound of the siren now coming from the pipeline at a certain point penetrates, an acoustic signal indicates that there is a fault in the Must be in the pipeline.
