[Industrial applications]

 The idea is to make a corrugated board sheet that is pasted with a double facer in a corrugated board manufacturing machine. More specifically, the present invention relates to a corrugated sheet corrugated sheet crease forming crease for forming corrugated sheet sheets, and more particularly to a corrugated sheet corrugated sheet crease forming crease capable of providing two or more differently shaped wires.

[0002]

[Prior art]

 In a corrugated board manufacturing machine that manufactures corrugated board sheets, a plurality of slitters are arranged coaxially in the widthwise direction of a traveling corrugated board sheet, and a scorer is arranged on the same axis in the widthwise direction on the downstream side of the slitter row. Therefore, a pair of the above slitter scorers are installed on the same line, and when one is in use, the other is adjusted in width in preparation for the next order. Then, the slitter was used to cut into a case size for making a corrugated cardboard sheet, and a scorer (ruled type) was used to apply a required number of ruled lines.

Further, as shown in FIG. 6, for example, the box making machine in the corrugated board manufacturing machine includes a sheet supply section 2 for supplying a corrugated board sheet 1, a printing section 3 for printing on the corrugated board sheet 1, and a corrugated board sheet with a creaser die. 1 is composed of a ruled pattern part 4 for applying a ruled line, a slot part 5 into which a notch is formed, and a feeding part 6. Conveying rollers 7 and 8 are appropriately provided above and below the conveying line L of the corrugated board sheet 1.

Then, the corrugated cardboard sheets 1 on which the kickers 2 a of the sheet supply unit 2 are stacked are fed to the printing unit 3 from the lowest one. In the printing unit 3, the fed corrugated sheet 1 is printed in a predetermined color and then fed to the ruled pattern unit 4. In the creaser section 4, as shown in FIG. 7, the folding points are subjected to ruled line processing by rotation of a pair of upper and lower ruled dies 4a and 4b, and then fed to the slot section 5. In the slot portion 5, a pair of upper and lower rotary blades 5a and 5b are rotated to make a necessary cut as a packaging box, and the feed portion 6 is fed. In the feeding section 6, the pair of upper and lower conveyors 6a and 6b feeds the sheets to a stacker or the like.

[Problems to be solved by the device]

 In the corrugated board manufacturing machine, the position of the rotary blades of the slitter, scorer, creaser, and slotter had to be changed when the order was changed, and the shape of the blades of the scorer and creaser was often changed. In particular, in recent years, in response to diversifying consumer needs, the production of products has been reduced to a large variety of small lots, and along with this, cardboard boxes for storing products have also been reduced to a large variety of small lots. Also, with the development of printing technology, color printing (solid printing) has become possible over the entire surface, including ruled lines, but the use of ruled lines sometimes spoils the appearance. Furthermore, when creases are applied to a corrugated cardboard sheet having a relatively low step, if the creases are applied with a strong force, the crease processing may impair the durability of the cardboard case. Therefore, the change of the set position of the rotary blade of the scorer and the creaser and the change of the rotary blade are also frequently performed, and it is desired to be performed promptly to prepare for the next order.

The present invention has been made in view of the above points, and it is possible to quickly apply a ruled line having a shape different from that of the previous order in response to the next order by slightly changing the position on the same axis. The purpose is to provide a corrugated liner for forming corrugated cardboard sheets that can be formed.

【Example】

 An example of an embodiment of a corrugated board crease forming ruled form according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a front view showing an example of an embodiment of a corrugated board crease forming corrugated die according to the present invention. FIG. 2 is a perspective view of a ruled ruled die which is a main part of the ruled die for forming a sheet fold according to the present invention. This crease for corrugated cardboard sheet creases is a crease for making creases in the flow direction according to the size of the case for making corrugated cardboard sheets that are pasted with a double facer in a corrugated board manufacturing machine, or a crease in a direction perpendicular to the creases in a box making machine. This is a ruled type for forming folds, such as a ruled type for forming ruled lines.

In FIG. 1, the sheet crease forming ruled die A is composed of a pressed ruled die 12 axially attached to a rotating shaft 11 and a receiving ruled die 14 axially attached to a rotating shaft 13. The rotating shaft 11 is rotatably supported by an eccentric bearing or the like on a frame of a corrugated board manufacturing machine (not shown), and is vertically movably supported. The ruled line die 12 mounted on the rotary shaft 11 is, for example, in the form of a roll in which an acute-angled head 12a is formed as shown in the drawing, and creases the corrugated cardboard sheet 1 passing therethrough.

The rotary shaft 13 is rotatably supported by an eccentric bearing and the like in the frame of the corrugated board manufacturing machine like the rotary shaft 11 in the upper stage, and is also movably supported for lifting and lowering. As shown in FIG. 2, the ruled ruled mold 14 mounted on the rotary shaft 13 is an essential part of the present invention. For example, as shown in the drawing, an acute-angled convex head 14a and a V-shaped concave head 14a are provided. A corrugated line is shown on the corrugated cardboard sheet 1 which is provided with a flat head 14c and a flat flat head 14c, and which cooperates with the ruled die 12 and passes between the ruled dies 12 and 14.

FIG. 3A is a front view showing a state in which the convex head 14a of the receiving ruled mold 14 is arranged directly below the head 12a of the pressed ruled mold 12, and FIG. FIG. 3 is a schematic end view of the corrugated cardboard sheet 1 in which the ruled lines 1 a are provided in the arrangement state 3 (a). 3A and 3B, the convex head 14a of the receiving ruled mold 14 is moved directly below the head 12a of the pressing ruled mold 12 to move the head 12a of the pressing ruled mold 12 and the receiving ruled mold. The corrugated cardboard sheet 1 that has passed through the gap a between the 14 convex heads 14a is continuously provided with sharp-edged ruled lines 1a from both sides. The gap a is slightly smaller than the thickness of the corrugated cardboard sheet 1 passing through. Such ruled line processing is used for normal corrugated board processing. The head 12a of the pressing ruled die 12 and the convex head 14a of the receiving ruled die 14 may have an acute angle or an obtuse angle, or may have a rounded shape.

FIG. 4A is a front view showing a state in which the concave head 14b of the receiving ruled die 14 is arranged directly below the head 12a of the pressing ruled die 12, and FIG. It is a schematic end view which shows the state which provided the corrugated line 1b in the corrugated-cardboard sheet 1 in the arrangement state of (ii). 4A and 4B, the concave head 14b of the receiving ruled die 14 is moved directly below the head 12a of the ruled ruled die 12 to move the head 12a of the ruled ruled die 12 and the receiving ruled die 12a. As shown in FIG. 4B, the corrugated cardboard sheet 1 passing through the gap b between the concave heads 14b of 14 is continuously provided with a V-shaped irregular ruled line 1b. The gap b is slightly smaller than the thickness of the corrugated cardboard sheet 1 passing through. Such ruled line processing is used for processing relatively thin corrugated board sheets such as E flute. The concave head 14b of the receiving ruled mold 14 is not limited to the one shown in the figure, and the concave shape may be an acute angle or an obtuse angle, or may be rounded.

FIG. 5A is a front view showing a state in which the flat head 14 c of the receiving ruled die 14 is arranged directly below the head 2 a of the pressing ruled die 12, and FIG. FIG. 5 is a schematic end view showing a state in which a corrugated line 1c is provided on the corrugated board sheet 1 in the arrangement state of 5 (a). 5 (a) and 5 (b), the flat head 14c of the receiving ruled mold 14 is moved right below the head 12a of the pressed ruled shape 12 to move the head 12a of the pressed ruled shape 12 and the receiving ruled mold. As shown in FIG. 5B, the corrugated cardboard sheet 1 passing through the gap c between the 14 flat heads 14c is continuously provided with a concave ruled line 1c only on one surface. By applying the ruled line 1c only to this one side, solid printing can be performed on the smooth surface. The gap c is set to be slightly smaller than the thickness of the corrugated cardboard 1 that passes through. Although a plurality of heads 14a, 14b, 14c having a convex shape, a concave shape, a flat shape or the like have been described above as the receiving ruled mold 14, it is sufficient that two or more heads are connected in series. It is also possible to connect a plurality of heads to each other.

[0017]

As described above, since the crease forming ruled pattern of the corrugated board sheet according to the present invention adopts the ruled pattern in which a plurality of heads such as a convex shape, a concave shape, and a flat shape are arranged in series, Order changes with different shapes can be handled with a slight movement on the same axis without replacing the ruled pattern as in the past. Therefore, it is possible to respond swiftly to the production of small lots of a wide variety of products that meet the needs of consumers without creating a large time loss, and its economic and practical effects are extremely large.
