Description

Technical Field

[0001] The utility model relates to a device for detecting whether the inner diameter of a coiled material without a sleeve is deformed. Background Art

[0002] In the prior art, the automatic coil feeding sequence of the rolling mill preparation station is: the coil is lifted on the conveyor line → the coil is fed to the height alignment device and stopped → the height alignment device swing arm falls → the coil transport trolley is lifted until the height alignment grating is in place → the height alignment device swing arm rises → the coil is fed to the preparation station unwinder position for cutting. The coils delivered on site include those with sleeves and those without sleeves. There are two situations: 1. When feeding coils with sleeves, the default inner diameter is close to a perfect circle. When the height alignment position is correct, the coil can be fed normally (such as Figure 1 2. When feeding coils without sleeves (usually blanks), due to some special circumstances, the inner diameter may be elliptical. The height position may be correct, but in some places, due to the deformation of the inner diameter, it cannot pass through the reel, causing scratches. If you are not careful, there will be a safety hazard of rolling (such as Figure 2 as shown).

[0003] For ease of understanding, the 0 o'clock position of the sleeve cross section is defined as A, the 3 o'clock position is defined as B, the 6 o'clock position is defined as C, and the 9 o'clock position is defined as D. Figure 1 The A, B, C, and D points shown have no scratches on the scroll. Figure 2 There are scratches between the B and D points shown and the scroll.

[0004] Therefore, it is necessary to redesign a device for detecting whether the inner diameter of the coil without a sleeve is deformed to avoid the inner ring of the coil from scratching the reel. Utility Model Content

[0007] Preferably, the sensing probe is a grating, wherein the sensing probes of the left and right detection frames at corresponding end positions form a group of opposing gratings.

[0008] Preferably, the upward and downward swing angles of the rotating swing frame are both 90°.

[0009] Preferably, the distance between two transverse sensing probes on each detection frame is equal to the distance between two vertical sensing probes.

[0010] Preferably, the driving mechanism adopts a motor or a pneumatic cylinder or a hydraulic cylinder.

When the grating signal at any of the three points B, C, and D is abnormal, it indicates that the inner diameter of the coil may be elliptical or have other deformations, and manual inspection by staff is required.
