FIG. 2 is an explanatory view showing a thickness measuring unit of the signature inspection apparatus according to the present invention. A signature 13 folded by a folding machine or the like is transported in a partial state by a transport device. A thickness measuring sensor 11 serving as a signature thickness measuring means is attached in the middle of the transport device. Normal,
The signature is in a state where one large sheet is folded (folded) several times by a folding machine or the like. For this reason, a force for returning the sheet to the original state is generated, and the signature may swell slightly. In order to accurately measure the thickness of the signature while suppressing the swelling, rollers 12 are arranged before and after the thickness measuring sensor in the transport direction of the transport device.
For example, by using a contact displacement sensor or the like as the thickness measurement sensor 11, the thickness of the signature 13 being conveyed on the conveyance device is continuously measured, and the thickness is sequentially output to the processing determination means. This thickness measuring sensor may use any method as long as it can measure the thickness of the signature.

When the operation is started, first, in step S1, reading of set values and calibration are performed as initial settings. When the operation is completed, a calculation is performed using the signature thickness measured by the signature thickness detecting means.
Specifically, assuming that the measurement is taken on the dotted line portion of the signature as shown in FIG. 5, each measurement point has a substantially constant thickness in both the vertical and horizontal directions as in the case where there is no defect in the signature in FIG. (T
(X-1, y) ≒ T (x, y) ≒ T (x + 1, y), T
(X, y-1) ≒ T (x, y) ≒ T (x, y + 1)).
Therefore, both y in steps S2 and S3
And it is determined in step S4 that the signature is normal. However, if a defect occurs, (B)
The thickness of the defective portion changes with the break of (C).
In the case of (B), the thickness in the vertical and horizontal directions is thicker at the measurement point where the measurement is overlapped than the normal part, and is thinner at the measurement point where the paper is missing (T (x + 1). , Y) <T (x−1, y) <T (x,
y)). Further, in the case of the tear in (C), when the thickness in the lateral direction is compared with the normal part, it is found that the measurement point where the tear occurs is thinner (T (x−1, y) <T).
(X, y) ≒ T (x + 1, y)). In this case, step S
2 or n in step S3, and it is determined in step S5 that the signature is defective. In this way, the comparison of the thickness of the same signature is performed an arbitrary number of times in the vertical and horizontal directions as shown in steps S6 to S10, so that the presence / absence of a defect of the signature can be determined.

As another determination means, instead of comparing the measurement points as described above, a predetermined threshold value is compared with the value of the measured data. Can also be determined. An example of the operation of the processing determining means is shown in the flowchart of FIG.

In this case, the range of the normal thickness of the signature is determined in advance. Here, the thickness of the signature is T (x, y),
The upper limit of the thickness is Tmax (x, y), and the lower limit of the thickness is Tmi.
Let n (x, y). First, initialization is performed in step S11. In step S12, the thickness of the signature is Tmin.
If (x, y) <T (x, y) <Tmax (x, y), it is normal in step S13, otherwise, step S1
4 is determined to be defective. Such a determination is made in step S15.
By performing the above for each measurement point as shown in step S19, it is possible to determine whether or not the signature is defective.

Here, an example is shown in which a signature is conveyed on the conveying device, but the same applies to a case where the signature is conveyed in a scale as shown in FIG. However, since the thickness of the transport device in the flow direction varies greatly at the folded portion, the inspection is performed only in the direction normal to the flow direction.
