Definitions

  • the present invention relates to a control and diagnostic unit for a pneumatic tool, in particular for a portable pneumatic tool for machining surfaces.
  • Portable tools for machining surfaces operating under the pneumatic action of a compressed air feed are known.
  • the aforesaid tools require maintenance operations whose frequency cannot be predicted beforehand but depends instead on the degree of wear of the tool, which in turns depends on the working hours of the tool itself.
  • a second object of the present invention is then to provide a control unit for a pneumatic tool which also allows to constantly display the working pressure of the tool.
  • a yet further object is to provide a control unit for a pneumatic tool which allows to provide data measured by an external central unit to allow the latter to control at the same time the working conditions of several tools.
  • the present invention envisages a control and diagnostic unit for pneumatic tools, which is characterised in that it comprises a feeding pressure sensor adapted to measure the pressure of the air fed to the tool, an electronic circuit for counting and storing the output time of said feeding pressure, and at least one indicating device adapted to indicate the instant at which said output time exceeds a predetermined time indicating the need for tool maintenance.
  • control unit includes a device for displaying the feeding pressure detected by said pressure sensor.
  • control unit is provided with an interlace device, such as for example an optical infrared port or a WI-FI device, which allows to remotely access the measured information and possibly to dialogue with the control unit.
  • an interlace device such as for example an optical infrared port or a WI-FI device, which allows to remotely access the measured information and possibly to dialogue with the control unit.

  • figure 2 shows even more schematically but on a larger scale the aforesaid control and diagnostic unit
  • figure 3 shows a block diagram of said control and diagnostic unit.
  • Figure 1 schematically shows, by the way of example only, a portable pneumatic tool for machining surfaces which is indicated as a whole by the number 1 and comprises a body 2 with a grip 3.
  • the grip 3 is passed through by an internal longitudinal channel 4, by which, during the working periods of the tool, air at appropriate pressure is fed for operating the tool motor (not shown).
  • the grip 3 is associated to a control and diagnostic unit 5 according to the present invention which, as shown in figure 2, comprises a pressure sensor 6 communicating with said feeding channel 4 and adapted to measure the pressure of the air fed into said channel.
  • Unit 5 powered by an electrical battery, also comprises a display 7, for example a liquid crystal display, for displaying the pressure measured by the sensor 6 and a plurality (three in the example shown) of light indicators 8, preferably LEDs of different colours, whose objects will be explained above.
  • a display 7 for example a liquid crystal display, for displaying the pressure measured by the sensor 6 and a plurality (three in the example shown) of light indicators 8, preferably LEDs of different colours, whose objects will be explained above.
  • Unit 5 also comprises within an electronic circuit 9, shown in figure 3, which essentially includes an analogue-digital converter 10, a clock 11 and a microprocessor 12 provided with a non- volatile memory 13. There is also provided an interface device 14, for example an infrared optical port or WI- FI device, which allows the control unit to dialogue with external units.

  • the pressure of the air fed through the channel 4 during the working time of the tool is constantly detected and measured by the sensor 6 and its value is sent as analogue signal to the converter 10 (fig. 3), which converts it into a digital signal which the microprocessor 12 uses to display the pressure value on the display 7 and thus to allow the continuous control of the working pressure, changeable by appropriate means not shown.
  • the starting of the working time of the tool determined by the presence of pressure in the channel 4, in turn causes the starting of the clock 11, by means of the digital signal thus generated at converter output 10, which clock sends counting data to the microprocessor 12, which stores them in memory 13.

Abstract

L'invention concerne une unité de contrôle et de diagnostic associée à un outil pneumatique pour l'usinage de surfaces, cette unité comprenant un détecteur de pression d'alimentation (6) conçu pour mesurer la pression de l'air acheminé vers l'outil, un circuit électronique (9) destiné à compter et mémoriser le temps de sortie de la pression d'alimentation, et au moins un dispositif indicateur (8) conçu pour indiquer l'instant auquel le temps de sortie dépasse un temps prédéterminé, d'où la nécessité de réaliser une maintenance pour l'outil. Un afficheur (7) permet d'afficher la pression d'alimentation détectée par le détecteur de pression (6). Un dispositif d'interface (14) peut être utilisé pour communiquer des informations à une unité centrale externe.
