Detailed Description

The utility model is further described below with reference to specific examples and figures.

As shown in fig. 1, a protection device for stacking metal bars on line is provided, a V-shaped frame 3 with an upward opening is arranged in the middle of a flaw detection platform 1 of a production line, guide wheels 2 for conveying the bars 8 are respectively arranged on the left side and the right side of the platform 1, the left guide wheels 2 send the bars 8 of the previous production line into the V-shaped frame 3, a flaw detection probe 4 is arranged at the other end of the V-shaped frame 3, a laser sensor 5 is arranged right above the middle of the V-shaped frame 3, the laser sensor 5 is fixed by a bracket on the platform 1 (for clearly displaying other components, the bracket is not shown in the drawing), a laser beam 6 emitted by the laser sensor 5 is vertically downwards aligned with the bars 8, the output end of the laser sensor 5 is connected to a main controller 7, the main controller 7 is connected to a power control system of the guide wheels 2 and is integrated with an alarm device, a normal sensing distance range from the laser sensor 5 to the bars 8 in a non-stacking state is set in the main controller 7, and when the sensing distance measured by the laser sensor 5 is smaller than the set normal sensing distance range, the main controller 7 receives the laser sensor 5, the power control system is controlled to stop the power control the guide wheels 2 and the alarm device emits an alarm signal.

As shown in fig. 2 and 3, the included angle of the V-shaped frame 3 is 100 degrees, and the angle cannot be too large, so that the stacked bar 8 can be rapidly monitored by the laser sensor 5, fig. 2 is a normal state, fig. 3 is a stacked state, when the bar 8 is stacked, part of the laser beam 6 emitted by the laser sensor 5 hits the stacked bar 8, the sensing distance is shortened, and thus the occurrence of stacking is judged.

The laser sensor 5 can be adjusted up and down at the fixed position of the bracket on the platform 1 so as to adapt to the stacking monitoring of bars 8 with different specifications.

The distance between the laser sensor 5 and the flaw detection probe 4 in the horizontal direction is larger than the inertial movement distance of the bar 8 generated by the conveying power of the guide wheel 2. Namely, the laser sensor 5 measures an abnormal sensing distance range, and the main controller 7 controls the power control system of the guide wheel 2 to stop running of the guide wheel 2, so that the distance that the bar 8 continuously moves due to inertia is smaller than the distance between the laser sensor 5 and the flaw detection probe 4 in the horizontal direction. The flaw detection probe 4 is not extruded by the stacked bars 8.

After the bar 8 is stacked, the guide wheel 2 stops running, after the stacking treatment, the main controller 7 controls the guide wheel 2 to automatically resume running after a certain time (such as 5 seconds) is separated from the laser sensor 5 after measuring that the distance between the bar 8 and the main controller is within the normal sensing distance range.

The alarm device is an audible and visual alarm.

Before the flaw detection production line starts to run, the position of the laser sensor 5 is set according to the specification of the bar 8, then the sensing distance from the laser sensor 5 to the bar 8 is measured, and a normal sensing distance range is set. After the flaw detection production line starts to run, the guide wheel 2 on the platform 1 sends the bar 8 of the last production line into the V-shaped frame 3, the laser sensor 5 above the V-shaped frame 3 measures the distance of the bar 8 passing through the V-shaped frame 3, when the laser sensor 5 measures that the distance of the bar 8 passing through the V-shaped frame 3 is smaller than a preset normal sensing distance range (as in the state of stacking in fig. 3), the main controller 7 controls the power control system of the guide wheel 2 to stop running and controls the alarm device to send an alarm signal, after a worker processes the stacking problem, the alarm device stops alarming, and the main controller 7 controls the guide wheel 2 to automatically resume running after a certain time interval. In this way, the flaw detection probe 4 can be protected from crushing by the stacked bar material 8.
