Abstract

PROBLEM TO BE SOLVED: To perform a working without any trouble even in the punching of a product even when the width of a trim is extremely small by forming notches having prescribed intervals, width and depth on the edge of the strip steel cutter of a trimming die body to form a 'joint' for connecting the product part to the trim. SOLUTION: A cutting edge 2 consisting of strip steel cutter is planted and fixed to the surface of the base plate 1 of a trimming die body A, and notches 3 are formed at prescribed intervals on the edge of the cutting edge 2 on three sides excluding a grip side 1a. When a sheet Y is peformed for flat board punching, 'joints' for connecting a product part to a trim in proper positions of the slit for partitioning the product part from the trim are formed, whereby the product part and the trim part are connected and held without being separated to each other. In the following stripping process, the 'joint' parts are cut by the action of a female discharging spring and a male holding blade. Even if the trim dimension excessively added to the outside of the product dimension is significantly small (2 mm at the minimum), the product punching can be performed without any trouble.

2. Description of the Related Art A packaging box is punched out of a flat plate such as a cardboard sheet or cardboard into various shapes depending on the contents to be packaged, and is assembled by assembling. Sheets such as corrugated cardboard and cardboard that are used to punch the unfolded shape of the box are naturally large enough to accommodate the unfolded shape, but maintain the quality of the box formed by punching. In view of this, a sheet cut generally larger than the product size is prepared. The material sheet is of a size that provides a crosspiece (or trim) around the product part in the unfolded shape, and is necessary to punch out the unfolded shape and dimensions of the box of the product part in a perfect shape. This is a part that is not included, and a width of about 7 mm to about 15 mm is usually added to the crosspiece.

[0003] However, corrugated cardboard sheets, which become sheets of material, are bonded together by a corrugate, and the size of the sheet supplied to the punching device is automatically cut by an instruction set at the time of bonding. The width is 7
It is added at a constant rate within a width of 1515 mm.
Then, the sheet of this material is added to the unfolded dimensions of the box, and the weighing is calculated using a square meter, and the unit price per sheet is calculated. If possible, the sheet unit price of the material can be set appropriately, and it is possible to contribute to the reduction of waste.

[0007] The male form of the stripping means for separating the product portion and the crosspiece width from the sheet cut into the expanded shape by the removal main body is a strip iron blade assembled to the removal main body on a flat rectangular base plate. A cross-width extruder comprising an L-shaped plate is formed along the shape, and a product portion formed on a sheet by the notch and a product at the position corresponding to the notch formed in the steel band blade of the punching body. A holding blade for cutting a "joint" portion connecting the cross section defined outside the section is provided between the cross width pushers. The holding blade is formed by bending a single saw blade or a double saw blade into a substantially U-shaped plane, and forms a cutting blade portion for cutting a “joint” portion at a substantially central position of a straight side portion between the bent sides. At the same time, concave portions are formed on both sides of the cutting blade portion so as to be fitted with a discharge spring attached to a female die described later. And
The holding blade is attached to the base plate at a predetermined interval outside the product dimensions.

According to the above-mentioned means, when a cut is made in the sheet by the punching body, the product portion and the outer crosspiece width are connected at predetermined intervals to the remaining three sides except for the grip side of the sheet. Is formed. The product portion and the crosspiece portion cut into the sheet by this "joining" are connected and held without being separated, and are transferred to a strapping process. Then, when the sheet is mounted and held on the female mold for performing the strapping process, a “splice” portion of the sheet is held by a discharge spring attached to the female mold, and the sheet is lowered by the male mold. The crosspiece is separated from the product part, but the "joint" is cut by the action of the female discharge spring and the male retaining blade. This makes it possible to reliably cut and separate even if the crosspiece width is narrow.

As shown in FIG. 6, the discharging spring 7 is formed by bending a metal wire into a flat concave shape and forming a male B
A receiving recess 7a into which the first cutting blade 6a is fitted is formed.
Support portions 7b are formed on both sides of the receiving recess 7a to uniformly support both sides of the "joint c" portion of the sheet, and the open ends on both sides extend rearward and are formed in a coil shape to form a shaft mounting portion. 7c are formed. The discharge spring 7 is provided in a mounting recess 8 formed by cutting out the outer peripheral edge of the female die B2, a spring support 9 formed by bending a flat metal plate into a substantially convex cross-section, and a shaft 10 which is horizontally mounted on the spring support 9. The discharge spring 7 is attached to the shaft 10 as the male mold B1 descends.
, The coil-shaped shaft mounting portion 7c is contracted during this downward rotation to accumulate resilient force, and the male die B1 is lifted after the stripping process is completed and discharged. The spring 7 returns to the horizontal origin position by the elastic force and waits for the next stripping process. Since the end of the shaft mounting portion 7c of the discharge spring 7 is in contact with the veneer plywood constituting the female die B2, a steel plate 11 is attached to the bottom of the mounting recess 8 which is in contact with the end of the shaft mounting portion 7c. Is attached to prevent the abrasion deformation of the portion, thereby preventing the attachment state of the discharge spring 7 from being changed.

The male blade B1 of the stripping means B is provided with a holding blade 6 having a cutting blade portion 6a at a position corresponding to the "joint c", while the female blade B2 is provided with the holding blade 6 of the male die B1. Correspondingly, the discharge spring 7 is mounted so as to be resiliently movable up and down, so that the outer side of the line of the "joint c" formed on the sheet Y by the lowering of the male die B1 (outer side of 0.5 mm from the product size). The cutting blade portion 6a of the holding blade 6 is held at the position, and the blade portion outside the concave portion 6b is pierced and held in the beam width b.
The cutting and separation of the beam width b is effectively performed by the pressure of the discharge spring 7 of the female die B2 supporting the lower surface of the sheet Y (resilient force for returning to the horizontal state). That is, the beam width b
Of the L-shaped plate provided on the male mold B1
Instead of pushing out only with the male blade B1, the "joint c" portion connecting the beam width b and the product a is pierced and held down with the holding blade 6 of the male die B1. Cutting and separation can be reliably performed even with the minimum possible cross width L3 (minimum 2 mm). Of course, it can also be used with the cross width (7 mm to 15 mm) which is generally used.
