"Control and diagnostic unit for pneumatic tool." * * * *
DESCRIPTION
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.
Furthermore, it is advisable to know the working pressure of the tool to ascertain if it is actually appropriate.
It is also appropriate to have remotely available the data related to working hours and working pressure of the tool so as to manage the maintenance of a number of tools by a single central unit.
It is precisely a primary object of the present invention to provide a control and diagnostic unit for a pneumatic tool, in particular a portable pneumatic tool for machining surfaces, which allows to obtain precise indications on the working hours of the tool and accordingly provides indications on the more or less urgent need for maintenance.
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.
In accordance with the aforesaid objects, 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.
It is also preferably envisaged that said control unit includes a device for displaying the feeding pressure detected by said pressure sensor.
It is preferably envisaged that said 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.
The features of the present invention will be explained in the following detailed description of an embodiment shown by the way of non- limitative example in the attached drawings, in which: figure 1 schematically shows a pneumatic tool provided with a control and diagnostic unit according to the present invention; 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.
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.
By effect of the structure described above, 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.
At the same time, 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.
In normal working conditions, the microprocessor 12 maintains ignited a first light indicator 8, for example green.
When the count reaches a first predetermined value indicating the reaching of a working time of the tool, and therefore of its expectable wear, which may suggest maintenance of the tool itself, the microprocessor 12 activates a second light indicator 8, for example yellow.
When the count exceeds the first value and reaches a second predetermined value indicating a working time and a wear so as to require urgent maintenance intervention, the microprocessor 12 activates instead a third light indicator 8, for example red.

AIl measured data may either be transmitted by the interface device 14 to an external central unit (not shown) or read by it for centralised management of a plurality of tools.
Although in the example shown in the drawings and described above, the control and diagnostic unit according to the invention was devised for a tool of the type with grip, it is evident that the aforesaid control unit can be combined with a hand-held type tool.
