Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention removes a sample sheet used in a device (rule pressure measuring device) that measures the bending strength of ruled lines (indents for bending paper plates and cardboard at predetermined positions) applied to paper containers and cardboard cases. The present invention relates to an apparatus for cutting a sheet (a product sheet punched by a punching die).

[0002]

[Prior art]

 In the paper box and the cardboard case, ruled lines are provided at predetermined dimensions so that the boxes can be assembled or the flaps can be bent smoothly. When a paper container and a corrugated cardboard case are put on an automatic packaging box making machine (auto caser) or an automatic sealing machine, inconvenience occurs depending on the strength of the ruled line, and the machine stops or a packaging defect occurs. For this reason, the creases incorporated in the punching die have been devised so that the thickness, height, head shape, etc. are within the allowable range of the bending strength depending on the specified paper quality. Then, in order to measure the bending strength of the ruled line, a sample sheet S having a specified dimension shown in FIG. 7 (a width (width) of a side parallel to the ruled line is 100 mm, a width of a side perpendicular to the ruled line (length) The width (width) is a rectangle of 150 mm, and the ruled line (a position 30 mm from one side of the vertical width) is cut out from a punched sheet (product sheet) 18 punched by a punching die.

A ruler 19 as shown in FIG. 7 is used to cut the sample sheet S from the punched sheet 18, and the ruler 19 is placed on the punched sheet 18, and a cutter knife is provided along the periphery of the ruler 19. The sample sheet S is cut out by moving. As shown in FIG. 7, in general, in a single punched sheet, the required strength for folding differs according to the folding order by an automatic packaging box machine (auto caser). , And a total of 12 measurement sample sheets are cut out from the lid and the bottom part F1 to F8. Furthermore, since the average value of the bending strength applied to the automatic packaging box making machine cannot be determined with only one punched sheet, 120 sample sheets are cut out from at least 10 punched sheets.

[0004]

[Problems to be solved by the invention]

 However, the work of placing a ruler on a punched sheet and cutting out four sides along the outer circumference of the ruler with a cutter knife does not work like a single stroke, and the force required for cutting is not uniform. Although one sheet requires a lot of work, 120 sheets requires a great deal of work. In addition, a thin cutter knife is used for cutting, but the load applied to the knife varies due to manual work, and the sharpness of the knife is significantly reduced just by cutting two or three pieces. Frequent replacement of the cutter blade is necessary to make the cut end look cut.

[0005] Furthermore, cutting the knife by running it along the outer circumference of the ruler requires careful attention from the viewpoint of safety, and there is a problem that the knife blade is broken. In terms of accuracy, there are many dimensional variations, and it cannot be said that this is an accurate sample sheet. In addition, since the ruler is pressed from above the punched sheet, the sheet may be crushed or may be connected without completely cutting the corners, in which case the ruled line will be forced to bend and the ruled line will be bent, making it unsuitable as a sample sheet. It is possible that

[0006] The present invention has been made in view of the above-mentioned problems of the prior art, and the problem is that a sample sheet used for a ruled line bending strength measuring instrument can be accurately and accurately extracted from a punched sheet. An object of the present invention is to provide a device that can be cut quickly and easily.

[0007]

[Means for Solving the Problems]

 The technical measures taken by the present invention to solve the above problems include a sheet mounting portion on which a punched sheet can be mounted on a substrate, and a guide lower than the surface of the sheet mounting portion on the left and right outer sides of the sheet mounting portion. A bar mounting portion is provided, and a bar holder is erected and fixed to the guide bar mounting portion, and two guide bars are laid across the sheet mounting portions in parallel across the bar holders. The two guide bars are provided with a cutter for horizontal cutting with a cutter attached to both sides at an interval corresponding to the width of the sample sheet, and a vertical cutter with cutters attached to both sides at an interval corresponding to the vertical width. A cutter holder for width cutting is slidably attached.A sample sheet is abutted against the edge of the substrate, and a scale for adjusting the ruled line position is attached. Characterized a configuration in which parallel to the groove whose serial two cutter attached to the cutter holder passes.

In the substrate having the sheet placing portion and the guide bar attaching portion, the sheet placing portion and the guide bar attaching portion are formed of separate members, respectively, and even if the both members are connected to each other, the substrate is formed as a single plate. The sheet placing portion and the guide bar attaching portion may be configured with a step. The two guide bars installed over the bar holder of the guide bar mounting portion may be a metal round bar or a square bar, and may be a lateral width cutting cutter holder slidably mounted on the guide bar. The center of the cutter holder for vertical width cutting is located on the same line. Therefore, two grooves are formed on the substrate and the scale at the positions equidistant from the center position to the left and right from the center position. Note that the width of the groove may be at least a width that allows the cutting edge of the cutter to enter. Further, the cutter holder for horizontal width cutting and the cutter holder for vertical width cutting to be attached to the guide bar may be arranged in front of the moving direction for cutting the cut sheet.

[0009] The cutters mounted on the cutter holder for horizontal width cutting and the cutter holder for vertical width cutting are positioned at a predetermined angle with the set groove and the rocket pin in the holder main body, and this is clamped by the holding plate. It may be configured such that it can be worn and detachably replaced. In the present invention, the cutting width of the horizontal cutting cutter holder is 100 mm, and the cutting width of the vertical cutting cutter holder is 150 mm.

According to the above-described means, the punched sheet punched by the punching die is placed on the substrate such that the trunk portion is positioned on the groove, and one side of the punched sheet is brought into contact with the scale. Then, when the width-cut cutter holder is slid along the guide bar, a 100 mm-width paper board is cut from the body by the left and right cutters attached to the width-cut cutter holder. Next, the cut section of the cut 100 mm wide paper plate is brought into contact with the scale, and the ruled portion applied to the paper plate is aligned with the ruled line alignment position displayed on the scale. When the cutter holder is slid along the guide bar, the left and right cutters attached to the vertical cutter holder cut a 150 mm wide piece of paper from the paper board. By these two cutting operations, a 100 × 150 sample sheet having a width of 30 mm on one side and a width of 120 mm on the other side is created with the ruled line as a boundary.
