[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper container such as a corrugated paperboard and a paperboard, and when punching the developed shape of the box on the material paperboard, punches of round holes and square holes processed inside the product and The present invention relates to a device for removing peripheral scraps on the outside of a product (external scraps obtained by punching a product from a master plate).

[0002]

2. Description of the Related Art Generally, in a paper container such as a cardboard box and a paper box, a product (developed shape) forming the paper container is punched by a flat die using a flat die and a rotary die using a cylindrical die. However, it is the mainstream of box making machines. The latter rotary punching machine separates product parts and scraps (both internal scraps inside the product and peripheral scraps outside the product) with sponges attached to the cylindrical cutting die due to centrifugal force caused by rotation during cutting. It is carried out.

On the other hand, there are two types of flat surface punching machines: a fully automatic punching machine and a method of performing the above-mentioned scrap removal processing after the product is completely punched. The fully-automatic punching machine is equipped with a device that, after being punched into the device, is instantaneously separated into a product and a scrap in the device by a stripping process of a male type and a female type. However,
Many punching machines that are not equipped with such a device for separating scraps are also in operation, and most of the waste removal processing when punching with such a punching machine is mostly manual labor. It has become.

[0004]

Therefore, since the work for separating the product and the scraps after punching is performed by pushing with a driver-like tool in the hand, the production efficiency is extremely poor.
Also, simple waste processing devices have been developed and used, but they take time to set, and at the same time, it takes time to prepare the parts before setting, and eventually manual work is more efficient. The reality is that it has not spread.

However, many kinds of small rods,
In addition, while the cost reduction is required, the manual work that requires a lot of manpower is not only unproductive but also inefficient. Therefore, the advent of a more efficient waste removing device has been desired. The conditions are: The device must be capable of handling scraps of any shape. 1. Easy and fast to set up, and does not require any preparations for setup. 1. The structure is simple and there are few failures. 1. The speed of scrap removal can be easily adjusted. 1. Can be easily restored even in an emergency.

The present invention has been made in view of the problems of the above-mentioned conventional technique, and an object thereof is to provide a debris removing device which can satisfy the above-mentioned conditions.

[0007]

The technical means taken by the present invention to achieve the above-mentioned object is to mount punched original plates in a stack at a middle position in the height direction of a frame which can be fixed and moved. Arrange the original plate mounting frame in which the position and size of the through hole for dropping the scrap depending on the position and size of the scrap, etc. are arranged horizontally, and above the original plate mounting frame, the shape of the scrap and the scrap A mounting base plate on which a corresponding push-out tool can be mounted depending on the position is vertically movably arranged, and the mounting base plate is connected to a pushing means fixed to a fixed substrate installed above the base plate, and is movable up and down. It is characterized by

The original plate mounting frame, in which the position and size of the through hole through which scraps are dropped, can be freely changed, is composed of a large number of vertical frames slidably mounted on rails which are fixed in opposition to each other inside a rectangular frame. Consists of crosspieces and detachable crosspieces that bridge over the crosspieces, and the lattice shape can be freely changed by combining the vertical crosspieces and crosspieces according to the position and shape of the scraps of the stamped original plate. It is possible to configure.

The mounting base plate has a structure in which elongated hole-shaped mounting holes are arranged and formed on a flat plate in a substantially zigzag pattern on a plane, whereby the mounting position of the pushing tool is adjusted to the position of the scraps of the stamped original plate. So that it can be changed. The attachment of the pushing tool to the mounting base plate is performed by forming a long groove on one side surface and forming a screw hole on the other side so as to detachably connect the support post of the pushing tool, and the long groove of the clamp body. A screw rod inserted into and engaged with the screw rod and a clamp knob screwed to the screw rod.The screw rod engaged with the clamp body is inserted into the mounting hole from below the mounting base plate, and the screw protruding from the upper face of the base plate is inserted. It is fixed to the mounting base plate by screwing the clamp knob to the rod.

Further, in addition to the form in which the push-out tool is directly attached to the above-mentioned mounting base plate, the push-out tool is a mold (male type) in which the push-out tool is arranged and attached on a flat plate in accordance with the punched original plate.
May be attached to the mounting base plate. The configuration is such that a pair of holding frames for holding and holding a male die in which a pushing tool is droopingly attached to a flat plate is provided on the mounting base plate so that the male die can be opened and closed, and a female die is connected to the male die by hanging. As a mechanism for opening and closing the pair of holding frames, a ball screw mechanism in which forward and reverse screws are formed on both left and right sides of the shaft, and a nut member is fixed to the left and right screws and screwed together is preferable. Further, examples of the pushing means for moving up and down the mounting base plate include an air cylinder and a hydraulic cylinder.

Further, the above-mentioned mounting base plate and push-out tool may have a suction structure by magnetic force, and the mounting position of the push-out tool may be freely changed according to the shape of the scrap and the pull-out position.
That is, the mounting base plate is a base plate having a built-in electromagnet, a base plate having a built-in or external permanent magnet, and the like so that a magnetic force is generated in the base plate. On the other hand, the pushing tool is

According to the above means, the opening of the original plate mounting frame is aligned with the position and size of the scraps on the stamped original plate, and the mounting base is provided with the pushing tool according to the shape and position of the scraps. Since it can be arranged and attached, scraps can be reliably removed in correspondence with any stamped original plate. And, the attachment of the push-out tool to the mounting base plate is surely made to the scraps of any place and shape by the mounting holes of the long holes formed in the mounting base plate and the staggered arrangement of the mounting holes. Can be set.

Further, for fixing the push-out tool which is hung down on the mounting base plate, a clamp main body which can be freely fixed / released by rotating the clamp knob on the base plate, and a column of the push-out tool relative to the clamp main body are fixed. Since the screw structure is detachable and replaceable, the pusher can be easily and surely set according to the shape and size of the scraps. In addition, the mounting base plate is provided with a holding frame that holds the scrap extrusion die (male type) in which the extrusion tool is fixedly fixed to the flat plate, so that the extrusion tool cannot be attached directly to the mounting base plate. It is possible to respond to the thing surely.

Further, when the pushing tool is attached to the mounting base plate by a mounting structure using magnetic force, the magnetic force is changed according to the position, shape, size, etc. of the scraps of the stamped original plate. Temporarily fix to the mounting base plate that has not occurred, and after the placement and temporary fixing of all the pushing tools are completed, the electromagnets of the mounting base plate are energized to firmly fix the pushing tools. Then, the push-out tool can be attached and detached by controlling the power supply to the electromagnet built in the mounting base plate.
