ない。 Making paper containers requires a process of punching out a board product of a predetermined shape from a board-shaped material such as paperboard. This punching requires the action of pressing a press plate against a punching die (hereinafter referred to as the cutting die) having a continuous blade corresponding to the predetermined shape, and cutting out the plate product from the plate-shaped material existing in between with the continuous blade. As a requirement, this must also include the feeding of materials, the separation of board products from waste, the collection of board products and the removal of waste.

拠するという欠点がある。 Conventionally, a punching device that attempts to automate the above series of operations is described in Japanese Patent Application Laid-Open No. 53-66086, but in this device, the material supply means uses a rotating reciprocating mechanism, and the cutting die and the pressing plate are connected to each other. The pressing means uses a linear reciprocating mechanism in a direction perpendicular to the direction of supply by the material supply means, and the cutting die is moved in a direction perpendicular to the direction of pressing by the press plate as a means for collecting plate products and removing scraps. Since another linear reciprocating mechanism is used, the structure is extremely complicated, and there are disadvantages in that the material supply means, press means, and sheet product recovery means each occupy a large space.

要時間を短縮化することを目的とする。 In view of the above points, the present invention uses a combination of a roller-shaped rotating pressing body and a cutting die that reciprocates in the horizontal direction, and the pressing body is moved half way around the bottom plate provided below the starting position of the cutting die, and then returned to the bottom plate. A returning endless material conveying means is provided, and a material gripper attached to the conveying means is operated by a cam provided in an arc shape along the circumferential surface of the pressing body, and the pressing body is rotated in synchronization with the forward movement of the cutting die. In addition, the product immediately after punching is held by a temporary suction holding means provided on the cutting die, and the product is dropped into the collection box below at the stopping position of the cutting die, thereby making it possible to supply and supply materials with a simple structure. This makes it possible to carry out a series of operations such as conveyance, punching, separation of sheet products and scraps, product collection and scrap removal, all during the unidirectional forward stroke of the punching die, and is especially effective for capturing sheet materials with a limited length. The purpose is to facilitate the separation of products and waste, and to shorten the time required from material supply to product collection and waste removal.

ることを防止できる。 It is necessary that the supplied plate material be fixed to the continuous blade and the pressing body when the cutting die moves. In order to move the supplied plate material while fixing it to the pressing body, instead of attaching the gripper to the chain as in the above example, a known structure is installed on the longitudinal end surface of the pressing body. A gripper may be attached. In that case, in order to prevent the material from rising from the circumferential surface of the pressing body, a press roller may be provided between the tip of the bottom plate and the top surface of the pressing body. Further, in this invention, since a cutting die equipped with a suction holding means is used, the suction force of this suction holding means is strengthened, and the supplied plate-like material is attracted to the cutting die and conveyed, and punching is performed. It's okay. The debris is caused to fall along the guide 23 due to its own weight. If necessary, a warping plate 25 may be provided as shown in FIG. Furthermore, when the cutting die is returned to the starting position, it is ejected from the suction pipe 4 by the compression action of the vacuum compression pump 6, and if it is sucked during forward movement, the material will be caught by the continuous blade when the cutting die returns. This can be prevented.
