いた。2. Description of the Related Art Conventionally, for example, printing is performed by a rotary printing machine,
It is folded by a folding machine into signatures and is conveyed in a scissor-like manner on a conveyor belt or conveyance rollers. The signatures that have been conveyed are aligned by a stacker and are integrated and packed. However, although stackers have been responding to the recent increase in speed of rotary printing presses,
When the signatures are disturbed, the limit of correction is exceeded, the signatures are jammed, and the printing machine is often forced to stop. Also, if the signature is folded or rolled up and conveyed, it will be packed as it is folded even if it does not get stuck in the stacker, eventually resulting in a defective product that cannot be used. there were. Therefore, conventionally, the operator monitors the stacker and removes or corrects it when the signature is disturbed, but as the printing speed increases, the stacker gets stuck in the gap when you take your eyes off the machine. It had to be stopped and returned to work, which was a cause of reduced production efficiency.

たと検出する。The height direction detecting means 3 has various methods such as a touch sensor for detecting that a signature is disturbed when it contacts in the height direction, a method of analyzing an image of a video camera or the like, and detecting a defect.
In FIG. 1, the light emitting / receiving unit 6 and the reflector 5 are combined. Of course, the light projecting unit and the light receiving unit may be used.

で図４で上下方向に飛び出すことになる。FIG. 4 is an explanatory view showing from above a state in which the signatures 13 overlap each other on the conveying path in a scissor shape and advance in the flow direction.
The disorder of the signature in the vertical direction means that the signature is projected in the direction perpendicular to the flow direction, as indicated by the vertical arrows in FIG. Further, when the signature is bent (rotated), the diagonal line is longer, so that the signature pops out in the vertical direction in FIG.

In FIG. 5, the up and down arrows indicate the disturbance in the height direction. Since one sheet is rolled up in the center of FIG. 5 and is higher than the other signatures 13, it is detected by the height direction detecting means 3.

Although they flow over the transport path 2 in a scissor-like manner, the height direction detecting means 3 first checks whether or not the signature is folded and lifted up. After that, the signature is pressed by the press roller 9 to make a beautiful crease. In order to prevent abnormal creases and even defective products from being pressed when pressing up to a height abnormality detected here, raise the press roller when a height abnormality is detected. It is also possible not to press.

可能である。Then, the orthogonal direction detecting means 4 detects the first disturbance of the signature in the orthogonal direction, and if it is not particularly detected, the side jogger 10 adjusts the disturbance in the orthogonal direction and the orthogonal direction detecting means 4 again. Detect the disorder of the signature in the second orthogonal direction. The detection accuracy is changed between the first time and the second time to widen the detection accuracy of the first time (that is, the interval between the two sets of sensors is, for example, the width of the signature plus 40 mm),
It is also possible to set the second detection accuracy (that is, the interval between the two sets of sensors, for example, the width of the signature plus 20 mm) to be narrow. When the first or second disorder of the signature in the orthogonal direction is detected, timing is measured to operate the reject conveyor to discharge the disordered signature from the discharge line. If these signatures are re-aligned, they can be used as plain paper. Further, the interval between the two sets of sensors can be automatically set by inputting the width of the signature.

It is explanatory drawing which conveys the signature 13 on the conveyance path 2 of this side. A signature conveyance disorder detection device (not shown) shown as an embodiment in FIG. 1 or 2 at the end of the conveyance path 2.
Is provided. This clip type signature carrier 12
Is an effective means of transporting a signature to a place away from the printing machine, but since it only adds the back of the signature with the clip 14, it is more effective than other signature transport systems. Conveyance disorder is likely to occur. Therefore, it has been found that it is very effective to use a rotary printing press, a clip type signature carrier 12, and a signature conveyance disorder detection device as a system. In the past, there was a clip type that detected the posture with a sensor, but there was no one that detected the disorder of the signature on the conveyance path in the height direction and the direction orthogonal to the traveling direction.

A system in which three belts are endlessly rotated in the transport path 2 is adopted. Since there is no belt on both sides of the transport path 2, the sensor is not blocked, and there is no problem even if the spacing is adjusted depending on the size of the signature. This signature conveyance disorder detection device is provided in the conveyance path before the stacker of a rotary printing machine, especially a gravure rotary press having a clip type signature carrier. Then, since it detects the disorder of the signature and automatically rejects it, the stacker does not get stuck in the defective signature. Further, as the detection sensor in the orthogonal direction, a sensor in which the light emitting portion and the light receiving portion are adjacent to each other can be used. This is due to irregular reflection when the signature is placed on the sensor section, and is formed by the adjacent light receiving section.

ことにより、検出精度を向上させることができる。According to the first aspect of the invention, the height direction detecting means can detect when the signature is bent or rolled up. This is to install a light sensor consisting of the light emitting unit and the light receiving unit or the light emitting and receiving unit and a reflecting member on both sides of the conveying path consisting of a conveyor belt, a roller conveyor, etc., to increase the normal flow height of the signature. A light beam is emitted at the position of alpha, and the signature disturbed in the height direction blocks the light beam so that the height direction can be detected and the apparatus is inexpensive. Further, the orthogonal direction detecting means can detect when the signature is protruding or bent in the direction orthogonal to the transport direction, and the disorder of the signature can be detected without fail. By providing a plurality of orthogonal direction detecting means in the flow direction of the transport path, the detection accuracy can be improved.

It is a combination of the above-mentioned signature transport disorder detection device and a printing system that feeds in a scissor shape on the transport path in front of the stacker by sandwiching the signature, and the stacker is clogged with an inexpensive detection device.
