Description

[Detailed description of the invention] This invention is a type of punching machine that punches the paper into the unfolded shape of the box and at the same time forms a folding groove. This invention relates to a ruled line indicator for a box-making paper punching machine, which is used to create ruled lines for pasting a board (folding groove plate).

Conventionally, paper substrates have been constructed as shown in FIGS. That is, in the same figure, a is a board, b is a cardboard attached to the board a with adhesive c, d is a vertically moving plate, e is a blade plate fixed to the vertically moving plate d, and f is also attached to the vertically moving plate d. A fixed ruled plate is shown, the blade plate e of which is fixed to the unfolded outer shape and notch portion of the box as shown in FIG. 1, and the ruled plate f is fixed to the bent portion. Then, the cardboard b is cut into the expanded outline of the box by so-called blank printing with a vertically movable plate d using carbon paper, and ruled lines are printed with a ruled plate f. Next, a groove _b1 was dug along the ruled line using a thin cutter or the like to form a ruled board.

However, in such conventional means, since the cardboard b is glued over a wide area to the board a, it takes a long time for the adhesive c to dry completely, and the grooves are formed along the ruled lines. It took a great deal of time even for an expert to dig _b1 .

Further, as shown in Fig. 3, by placing cardboard b on substrate a through carbon paper g and performing so-called blank printing in the same manner as above, the unfolded shape of the box and the ruled lines for folding are displayed on substrate a. , Next, as shown in Figs. 4 and 5, a face plate h, that is, a narrow plate made of plastic plates with a thickness of about 1 mm is placed on the left and right sides of the surface of the plastic sheet _h1 .
H ₂ is glued to form a groove H ₃ , and a non-drying adhesive H ₄ is applied to the back side of the plastic sheet H ₁ , and a face plate H is attached to this with a protective paper H ₅ removably glued. There is also a known method in which the protective paper _h5 is peeled off and adhered along the ruled lines of the board a, but in this method, the ruled lines are printed on the board a through the cardboard b. As a result, the ruled lines are not clear and it takes a considerable amount of time to attach the face plate h. It is important to note that unless the ruled line is displayed at the specified location on the paper to be punched, the face-cutting board h cannot be installed accurately, and the ruled board and blade plate e used to form the ruled line are based on the thickness of the paper at the time of punching. , unless the blade plate e protrudes slightly beyond the ruled plate f forming ruled lines by a predetermined height depending on the difference in type, the box cannot be accurately punched into a developed shape, and the ruled lines may be shifted from each other as desired. Since the ruled lines cannot be formed at predetermined positions on the paper to be punched, the paper is cut at the location where the ruled lines are installed, resulting in inconveniences such as being unable to be used as a product. Because of this, there were cases where it was not possible to form boxes in the correct shape.

The present invention was developed in order to eliminate the above-mentioned drawbacks, namely, the purpose of the present invention is to eliminate the time required for drying the cardboard of the conventional means, as well as to directly dry the substrate without using cardboard. By being able to print, extremely clear ruled lines can be created, and therefore the work of gluing the face plate can be done quickly and accurately, and the work of fitting the cap, which has a printing function, to the main body plate can be done as a punching work. Coupled with the fact that it can be done separately and easily, it eliminates lost time in punching work, reduces costs, and allows the paper to be cut by the contact of the ruled plate during punching, depending on the thickness and type of paper. To provide a ruled line indicator for a paper box-making and punching machine, which allows for good box manufacturing without causing inconveniences such as the vertical and horizontal ruled lines being distorted.

Next, an embodiment of the present invention capable of achieving the above object will be described in detail with reference to FIGS. 7 to 11.

1 is a main body plate, 2 is a cap made of natural rubber or synthetic rubber, and the main body plate 1 is a steel plate similar to a conventionally known ruled plate.

The cap 2 is lightweight and has left and right side plates that can be easily and accurately cut to the desired length using a tool such as scissors so that the length matches the length of the main body plate 1, which has the same shape as the ruled lines installed vertically and horizontally. 21 and the bottom plate 22 to form a thin approximately U-shape, and the lower part of the bottom plate 22 has a height slightly higher than the tip of the blade plate, and is pressed against the substrate a with sufficient pressing force. By protruding the contactable protrusion 23, the cap 2 is removably fitted to the main body plate 1. The lower part of the main body plate 1 is removably fitted into the groove 24 of the left and right side plates 21, but if the main body plate 1 is not further fitted so that this fitted state is firmly maintained. The left and right side plates 21 in FIG.
~D, it is formed in a tapered shape that becomes narrower toward the top.

As shown in Figures A to D, the protrusion 23 is formed into a rectangular shape, a tapered shape that becomes narrower toward the bottom, a rectangular shape with a notch 23a, an arcuate shape, or the like. Also protruding 2
3 is formed to have a width of approximately 1 mm and a height of the entire cap to be approximately 6 mm in order to ensure sufficient contact force against the substrate a.

Next, how to use the present invention will be explained using FIGS. 12 to 16.

For example, as shown in FIG. 12, in a state where the cap 2 protrudes from the vertical movement plate 3 on which a desired ply of veneer is laminated, the main body plate 1 and the blade plate 4 are
As shown in the figure, based on the unfolded shape of the box, attach the blade plate 4 to the cut point and the cap 2 to the bent part (note: the tip of the blade plate 4 is
In a state where the protrusion of cap 2 protrudes slightly, for example, by 0.5 mm. ) First, carbon paper is placed directly on the substrate 5 and so-called blank printing is performed, and thereby the 14th and 1st
As shown in FIG. 5, elongated plastic plates 62 having a thickness of about 1 mm are adhered to the left and right sides of the surface of a face-engraved plate 6, that is, a plastic sheet 61, thereby forming grooves 63, and a non-drying adhesive 64 is applied to the back surface. is applied, and a protective paper 65 is removably adhered thereto.
Then, as shown in FIG. 16, a face-cutting plate 6 is accurately adhered to a predetermined position vertically and horizontally on a substrate 5 using a non-drying adhesive 61, and then the punching operation is performed. At this time, when the cap 2 having the notch 23a at the lower part of the protrusion 23 as shown in Fig. 11C is used during the above-mentioned printing, when it is pressed normally, the width of the protrusion 23 and the width of the cap 2 are uniform. (For example, 1mm wide)
When printed and pushed strongly, the left and right sides of the protrusion 23 are expanded through the notches 23a, and the print is made wider than the width of the protrusion (for example, 1.5 to 2.0 mm).

Since the present invention is constructed as described above, it eliminates the need for the drying time of the cardboard bonded to the substrate in the conventional means, and also eliminates the need for printing on the substrate through the cardboard in the conventional means. , the ruled lines will not become unclear or the center will be biased, and therefore, the facing board can be adhered easily, quickly and accurately, and the cap fitting work can be done separately from the punching work and easily. Unlike what can be done, it eliminates the lost time of punching work, that is, it eliminates inconveniences such as paper being cut along ruled lines during punching or misalignment of vertical and horizontal fold lines depending on the thickness and type of paper. This has the effect of producing a box that can be manufactured well at a low cost.
