Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a corner cutting machine,

The present invention relates to a corner cutting apparatus for a printed matter, which comprises a cutter having a cross-sectional structure of arc, wherein an angle with respect to the center of the arc is at least 90 占 the end of the cutter bottom forms a blade, The cutter constitutes a cutter having at least one protrusion protruding in a recessed portion of the structure drawn inwardly of the arc, which is a cross section of the cutter, and a protrusion protruding in the opposite direction. The cutter, a holder for fixing the cutter, And the cutter is cut by the cutter while the holder and the cutter are lowered by the elevating means to prevent the sharpness of the corner of the printed material by the recessed portion and the protruded portion of the cutter , And to increase the esthetics of printed matter.

Typically, printed matter refers to books, magazines, pamphlets, catalogs, or documents printed on paper, such as slips, notes, business cards, and wedding invitations. Printed materials include printed materials, advertising, Such as office prints, securities printed matter, and special printed matter. These printed matters are generally used for conveying information. They are usually printed on rectangular paper, but business cards or wedding invitations cut (cut) corners, To prevent sharpness, to reveal personality and to enhance the aesthetic.

As an example of a method of cutting the edges of printed matter, Korean Utility Model Registration No. 0368213 discloses a method of cutting a corner of a printed product by cutting a cutting edge having a cross-section of a business card and a pair of auxiliary edges corresponding to both sides of the cut- , And a 'business card making device' that presses the cutting blade by pressing the cutting blade to produce business cards.

Korean Patent Registration No. 1544980 discloses a "corner round punching machine" in which a punch having a plurality of punching blades is formed on its periphery, and the punch is raised and lowered by a cylinder to punch round edges of workpieces such as business cards. .

However, since the first design described above uses a cutting blade corresponding to the size of the business card, a separate cutting blade is required depending on the size of the business card or the corner shape, and when the cutting blade is dull or damaged, There is a problem in that the cost of manufacturing the cutting blade and replacing the old blade is troublesome.

In addition, although the second example described above can be applied to workpieces of various sizes because only the corners of the workpiece can be machined, and the punching blade is composed of several different diameters of rounding, and there is a choice about the desired rounding diameter, Since several punching blades are integrated in the punch, it is not possible to replace only the damaged punching blades when one or a part of the punching blades are damaged. Since the punching blades can not be punched differently than the rounding punching blades, There has been a need to develop a cutter capable of cutting corners.

In order to solve the above problems, the present invention provides a cutter having a cross-sectional structure of arc, wherein the angle of the arc to the center of the arc is at least 90 占 the end of the lower portion of the cutter forms a blade, The cutter is constituted by a cutter having at least one protrusion protruding in a recessed portion of the structure drawn inwardly in the inward direction. The cutter, the holder for fixing the cutter, and the elevation means for moving the holder vertically, A cutter is constructed so that the printed matter is placed under the cutter and the holder and the cutter are lowered by the elevating means while cutting corners of the printed material by the cutter to prevent sharpness of the corner of the printed material by the recesses and projections of the cutter, Height.

Accordingly, the present invention provides a cutter having a cross-sectional structure of a arc, wherein the angle of the arc to the center of the arc is at least 90 占 the lower end of the cutter forms a blade, A cutter configured to form a cutter having at least one protrusion protruding to the opposite side of the cutter, a holder for fixing the cutter, and a lift means for moving the holder upward and downward, The printed matter is placed on the lower portion, the holder and the cutter are lowered by the elevating means, and the corners of the printed material are cut by the cutter to prevent sharpness of the corner of the printed material by the recesses and projections of the cutter.

A cutter for a corner of a printed material for enhancing aesthetics according to the present invention will be described first, and a printed corner cutting machine to which the cutter is applied will be described below.

First, as shown in FIGS. 1 and 2, the cutter 10 is formed in a arc structure having a cross section of at least 1/4 of a circle, and at the lower end, a blade 11 having a cross section that becomes narrower toward the bottom is formed And the blade 11 is a structure for forming a large number of decorative irregularities.

More specifically, the cutter 10 is formed such that its cross-section is in the shape of an arc and has at least 90 degrees with respect to the center of the arc, the height of which forms a suitable width and the bottom of which forms the blade 11,

The cross section of the cutter 10 and the blade 11 forms a uniform irregularity so as to enhance the ornamental appearance. The cross section of the blade 11 has a structure in which the cross section is drawn inward (in the direction toward the center of the arc of the cross- The concave portion 12 is integrally formed on both sides of the concave portion 12 so as to protrude outwardly (in a direction opposite to the center direction of the arc of the cutter cross-sectional shape) Or a cross section having an angle of 90 DEG. Likewise, the projections 13 may be formed outwardly convexly or may have a cross section having an angle of 90 DEG.

For example, as shown in Fig. 1, a concave portion 12 having a structure drawn in the center direction (direction of the center of the arc, which is the sectional shape of the cutter) is formed in the middle of the blade 11, 2, two protruding portions 13 protruding outward in the center direction may be formed on both sides of the blade 11, or the protruding portions 13 may be formed in the middle of the blade 11 in the center direction The protruding portion 13 having a section protruding convexly outward in the center direction, the concave portion 12 and the protruding portion (protruding portion) 13) are repeatedly formed.

As shown in Fig. 2 (E), a projecting portion 13 having a convexly protruding shape in the outward direction (the direction opposite to the center direction of the arc of the cross-sectional shape) is formed in the middle of the blade 11, And the protrusions 13, the concave portions 12 and the protrusions 13 are repeatedly formed on both sides of the recessed portions 12. The recessed portions 12 are formed in a plurality of locations on both sides of the recessed portions 12 in the center.

3 (F), the concave portion 12 having the structure drawn in the center direction (the direction toward the center of the arc, which is the sectional shape of the cutter) is formed in the middle of the blade 11, 12 are formed so as to have a cross section having an angle of 90 degrees, that is, a cross section drawn in a right angle.

As shown in Fig. 3 (G), the projecting portion 13 having a structure protruding convexly in the outward direction (direction opposite to the center direction of the arc of the cross-sectional shape) is formed in the middle of the blade 11, The protrusions 13 form a cross section protruding at an angle of 90 degrees, that is, a cross section protruding at a right angle, and the recesses 12 are formed at the inner side Thereby forming a cross-section taken in a right angle.

The cutter 10 having various structures cuts the corner of the printed material 20 with the blade 11 so that the corner of the printed material 20 is cut into the concavo-convex shape having the end face of the blade 11, By removing the sharpness, it is possible to increase the decorative property and the aesthetics according to the cut shape.
