Description

FIG. 1 shows a schematic side view of the device; in fig. 2 the same, top view; in fig. 3 - 5 sequence of submission and measurement of the part.

The device consists of a feeding device 1, for example a vibrating jepa, an inclined chute 2 for guiding parts 3, a supporting device 4 for locating parts 3 as they are monitored, sensors 5 and 6 for controlling horizontal dimensions, for example the diameter of parts, probes 7 and 8 of these sensors, mounted on rods 9 and 10, having on / end rollers 11 and 12 interacting through lever systems 13-16 with a cam-type distribution mechanism 17.

In addition, the device includes sensors 18 with probes 19 and actuator 20, allowing control of the dimensions of the parts vertically, such as their thickness. All sensors are connected via converter 21 to actuators 22 and 23 for addressing parts in bays 24 for suitable parts, bays 25 for parts with correctable deviations, and bays 26 for defective parts.

The device works as follows.

Parts 3 from the vibrating hopper 1 along the inclined tray 2 are fed to the measuring base of the support device 4 (Fig. 1 and 2). In the initial position, the probe 7 of the rod 9 of the sensor 5 is retracted to its extreme position, and the probe 8 of the rod 10 of the sensor 6 enters the zone of movement of the part 3, preventing its movement (Fig. 3). The probes 19 of the rods of the sensors 18 are located above the base of the base of the fixture .4 at a distance greater than the height of the parts. The probe 8 of the rod 10 of the sensor b, with its end support pad, holds part 3 at the measuring base of the device 4, and then through the cam

mechanism 17 with a drive, levers 16 and 14 with th 15, it triggers to measure the diameter of the part. After this, the probe 7 of the rod 9 of the sensor 5 operates on the measurement, abutting its end support pad in part 3 and simultaneously the compartment of the measured part from the main flow . Next, the measurement of the height of the part of the probes 19 of the sensor rods 18 is triggered. Then, a sorting device, which divides parts into suitable parts, parts with correctable defects and final defects, is activated from the sensor signal transducer to the address command part. In order to retract the monitored part 3 from the tool 4, the probes 8 and 19 of the sensors b and 18 are retracted from the part, the probe 7 of the rod 9 is retracted to the position indicated in FIG. 5, blocking the path of the next part until the part has completely left the tool 4. After that, all the probes occupy the initial position and the whole cycle repeats.
