Abstract

<P>PROBLEM TO BE SOLVED: To solve the problems wherein exclusive metal fittings and screws are required for mounting a die-cutter wooden pattern on a die-cutter roll when cutting a corrugated cardboard by the die-cutter roll and an anvil roll, one exclusive die-cutter wooden pattern is inevitably necessary for on shape to be cut, and it takes long time to attach and detach the exclusive die-cutter wooden pattern. <P>SOLUTION: Both ends of the die-cutter wooden pattern 2 is formed at a designated angle α, and is coincided with ring holders 1 mounted on die-cutter rolls 3, and are fixed by sliding to the ring holders 1. Thus, detachment and attachment of the die-cutter wooden pattern 2 becomes easy without using screws, and attachment and detachment time of the die-cutter wooden pattern 2 can be reduced. One die-cutter wooden pattern can be reused by turning over since the die-cutter wooden pattern 2 is fixed with an exclusive attachment by sliding it, and one die-cutter wooden pattern 2 can be used by combining with another die-cutter wooden pattern. Therefore, dimensional changes become easy by combining a plurality of die-cutter wooden patterns, and manufacturing costs can be reduced without preparing an exclusive pattern. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

The present invention relates to the mounting of a die cutter wooden mold in a die cutter apparatus that performs a punching process in a corrugated board processing apparatus that continuously performs printing, ruled line processing, punching processing, etc. on a corrugated cardboard sheet.

As described in Patent Document 1, a conventional die cutter wooden mold is fixed to a die cutter roll with a dedicated metal fitting or a screw. In addition, because the fixing method is dedicated metal fittings or screws, basically one special die cutter wood mold is required for one specified cutting dimension.
JP-A-2-53594

As mentioned above, it takes a long time to fix the die cutter mold to the die cutter roll with the dedicated metal fittings or screws. A dedicated die cutter mold was required, and there was a problem that many expensive die cutter molds had to be held.

    In order to solve the above-mentioned problems, the present invention provides a smooth exterior that forms a pair in parallel with a die cutter roll in which a die cutter wooden mold having a Thomson blade provided on an exterior surface of an arc-shaped plate-like body is attached. In the process of cutting the corrugated board material by pressing the die cutter wooden mold against the corrugated cardboard passing between the rotating anvil roll and the die cutter roll having the die cutter wooden mold provided on the exterior surface, which consists of a combination of an anvil roll having a surface, The left and right ends of the die cutter wooden mold are formed at a predetermined angle, and are positioned by sliding on the ring holder attached to the die cutter roll, and the inner periphery of the ring holder matches the both ends of the die cutter wooden mold. It is machined at a predetermined angle so that the die cutter wooden mold is slid, the attachment is fixed with screws, It is possible to position the die cutter wooden at an arbitrary position on the circumference of Taroru a cardboard processing apparatus that desorption can be easily performed.

    Furthermore, since the die cutter wooden mold is inverted 180 degrees and used, the dimensions between the die cutter wooden cutters can be changed, so there is no need to have a large number of dedicated die cutter wooden molds. Further, since the ring holder is provided with a notch for the die cutter wood mold slot, the die cutter wood mold can be easily attached to the die cutter roll. The outer surface of the ring holder is fixed by a ring lateral movement plate, and arbitrary positioning in the lateral direction can be easily performed by rotating the moving plate screw shaft.

    According to the die cutter wooden die attaching device of the corrugated cardboard cutting die cutter device according to the present invention, the die cutter wooden die is not fixed with a screw or the like as in the prior art, but is fixed with a ring holder, so the circumference of the die cutter roll Any position above can be positioned freely. Moreover, since it can be used in combination with several types of die cutter wooden molds and the dimensions between the cutters of the die cutter wooden molds can be freely changed, the number of die cutter wooden molds held can be reduced. Also, a die cutter wooden mold of a type that can be easily detached from the ring holder and fixed with a conventional screw can be used.

    Embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the die cutter unit pivotally supports an anvil roll (4) at the upper part, and is attached to the anvil roll (4) at the lower part of the anvil roll (4). (3) is pivotally supported. The die cutter roll (3) and the anvil roll (4) are rotated in opposite directions by driving a motor (not shown).

    Four ring holders (1) are attached to the peripheral surface portion of the die cutter roll (3). This ring holder (1) is used as a set of two wheels. The ring holder (1) is fixed at both ends by a ring lateral movement plate (9). The ring lateral movement plate (9) moves laterally by rotating the moving plate screw shaft (10). , Positioning to any position. The ring holder (1) is mounted concentrically on the die cutter roll (3).

Hereinafter, based on FIGS. 2-7, the usage method of a die cutter wooden form is explained in full detail. As shown in FIGS. 3 and 4, the ring holder (1) and the die cutter mold (2) are formed at a predetermined angle (α) at both ends of the ring holder (1) and the die cutter mold (2). Yes. As shown in FIG. 2, the ring holder (1) is provided with a die cutter wooden slot (8) by notching a part of the opposing surface of the pair of ring holders (1). Insert the die cutter wood mold (2) from the die cutter wood mold inlet (8), slide it in the circumferential direction as shown in FIG. 7, and set it at a predetermined position using the wood mold positioning scale (7). To do. The wooden positioning scale (7) may be marked on either the left or right of the pair of ring holders (1), or on both.

For the method of fixing the die cutter tree (2), as shown in Fig. 2, press the attachment (5) against the die cutter tree (2) and attach the attachment (5) to the die cutter roll (3). Secure with bolts (5a). Reference numeral 11 denotes a die cutter wood blade fixed to the die cutter wood die (2), and the die cutter wood die blade (11) is used to punch a corrugated cardboard sheet.

    The die cutter wood mold (2) is symmetrical, and the die cutter wood mold (2) is attached from the die cutter wood mold inlet (8) of the ring holder (1) as shown in FIGS. Since the die cutter wood mold (2) is inserted and slid in the circumferential direction of the ring holder (1) and held, the die cutter wood mold (2) can be used after being inverted 180 degrees. When a predetermined die cutter wood cutter size (6) is required, a die cutter wood die (2a) and a die cutter wood die (2b) are used in combination as shown in FIG.

    In addition, when a predetermined die cutter wood cutter size (6) is required separately, the die cutter wood die (2a) in FIG. 5 is inverted 180 degrees and used in combination with the die cutter wood die (2b). By doing so, the desired dimension (6) between the die cutter wooden cutters can be obtained as shown in FIG.

    An embodiment of the present invention will be described with reference to FIG. FIG. 8 shows a schematic diagram of a corrugated board processing machine, wherein A is a paper feeding unit, B, C, D, and E are printing units, and F is a corrugated board processing apparatus that is an object of the present invention.

    By using a ring holder attached to the die cutter roll and a symmetrical die cutter wood mold processed at a fixed angle on both ends, the die cutter wood mold can be fixed easily, and the die cutter wood mold is also reversed. Because it can be used, it can be used not as a dedicated die cutter wooden mold but as a dual-purpose die cutter wooden mold.
