  By the way, there are various shapes for folding the paper, such as a folded shape in which mountain folds and valley folds are repeated, or a folded shape in which mountain folds, mountain folds, valley folds, mountain folds, and valley folds are combined. In the case of folding a sheet in such a folding shape, a buckle folding machine having a plurality of sets of buckles and folding rollers is generally used. In this buckle folding machine, the leading edge of the paper to be advanced is inserted into a buckle whose insertion length is limited by a stopper, and the part that protrudes from the buckle and is bent is pinched by a folding roller to fold the paper at that part. Insert the folded tip into the buckle where the next insertion length is limited by a stopper, fold the paper out of the buckle with a folding roller and fold the paper at that location, while advancing the paper It is possible to fold a predetermined portion and fold a plurality of portions of the paper with one folding machine.

In order to stabilize the folding position of the paper, even in such a buckle paper folding machine, when a folding line is formed in advance in the paper to be advanced to the folding machine, for example, the paper that further folds the folded paper is hard. There is a case. In such a case, as one means for forming the fold line, a crease scoring roller having the above-described uneven rolls mounted for the number of folds is used. The folding lines formed by the folding lines are different by 90 degrees in the same direction as the paper traveling and the paper traveling direction of the buckle folding machine. For this reason, the crease scoring roller is disposed across the conveyance path that advances the paper in a direction orthogonal to the paper advance direction of the buckle folding machine. The position of the concavo-convex roll mounted on the folding line scoring roller is the position of the guide plate that guides the progress of the paper located on the buckle paper folding machine side of the conveyance path (the leading position of the paper that advances to the buckle paper folding machine) .) As a reference, the first folding position, the second folding position, and the position corresponding to the folding position in order.

  In a crease-creased roller equipped with such a concavo-convex roll, if the crease provided by the concavo-convex roll is slightly displaced from the folding position by the folding machine, it cannot be folded at the correct position. Therefore, it is necessary to accurately position the uneven roll at a position corresponding to the folding position. However, in this positioning, according to each of the pair of rotating shafts, a folded paper is formed on one rotating shaft, for example, a concave roll and a convex roll, and a convex roll, a concave roll and a convex roll on the other rotating shaft. After mounting, the position of the concavo-convex roll is adjusted to a position that accurately corresponds to the folding position. In such positioning, as the folding becomes more complicated, the combination and position of the concavo-convex rolls become more complicated, and there is a problem that even an expert needs a lot of time.

The problem to be solved by the present invention is that it is possible to accurately position the combination and position of the concavo-convex rolls in a short time even for complicated folding of paper, and to solve such problems. It is in.

In order to solve the above-described problems, the present invention is a position setting device for a crease / concave uneven roll mounted on each of a pair of rotating shafts installed in a paper conveyance path, wherein the position setting device includes: Positioning the machine frame that supports both ends of the two rotating shafts, the slider that moves along the two rotating shafts installed in the machine frame, and the tip of the convex roll fixed to the slider A control device comprising a gauge for instructing, a memory for storing folding data for controlling the position of the slider, and designation of convex rolls for positioning and positioning of the concave and convex rolls based on the folding data stored in the memory When the specified convex roll is set to a predetermined position determined based on the folding data, the slider is moved to the predetermined position, and the specified convex roll is displayed. The Lumpur positioned in accordance with the gauge, and configured to position the concave roll becomes the convex roll pair accordance positioning the the convex rolls.

According to the present invention, when the pair of rotating shafts to which the crease / concave uneven roll is attached are mounted on the paper conveyance path, the position of the crease / protrusion roll is moved according to the slider positioning gauge moved to the position to be set. Since it is set, anyone can set the crease / concave uneven roll to an accurate position in accordance with the folding position of the paper in a short time.
