[0002]
[Prior art]
Conventionally, the manufacturing process of paper containers such as corrugated cardboard usually includes a so-called punching process for punching a paper container material conveyed on a production line into a predetermined shape, and a so-called punching process for making a hole in a required portion of the paper container. A so-called residue removing step for removing residue remaining in the punched portion of the paper container punched and punched in the punching step / hole punching step.
[0003]
As means for use in the above-described hole punching process or hole scrap removal process, for example, one disclosed in Patent Document 1 is known.
[0004]
In other words, the male and female molds are used together, and a large number of upper pins constituting the male mold are formed in the shape of the punched portion on a plate that is driven up and down by a drive source using a hydraulic mechanism or a crank mechanism. A female mold provided with a corresponding arrangement, a female mold provided with pilot holes corresponding to the arrangement of the multiple upper pins is arranged below the male mold, and a paper container that has undergone a punching process is arranged on the female mold to drive the drive. The male die is lowered by a source, the male upper pin is advanced into the female lower hole portion, the paper container is punched or scraped, and the waste portion is dropped downward.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail.
1 to 4 show a female die 1 for punching according to an embodiment of the present invention. This female die 1 for punching includes a punching pin 12 (details will be described later) shown in FIG. In combination with the male punching die 11 provided in an opposing arrangement, it is used for punching a required portion of a paper container material 20 for manufacturing a paper container product such as a cardboard box.
In the present embodiment, as the hole punching male mold 11 used in combination with the hole punching female mold 1, the hole punching pin 12 is mounted on the lower surface side of the base that moves up and down by the drive source. In the present invention, the punching tool used in combination with the punching female die 1 according to the present embodiment, in addition to the punching male die 11 as shown, For example, a wide range of members may be used which are configured to punch holes at a required portion of the paper container material 20 with hole punching pins arranged above and below the paper container material 20.
[0014]
In this female die 1 for punching, a large number (e.g., eleven) elongated prismatic slide bodies 7 can be arranged in parallel by the support frame 2 having a rectangular shape as a whole, and the distance between them can be arbitrarily adjusted. Supports lined up.
The width w1 of the slide body 7 shown in FIG. 1 is set to 10 mm, for example, and the width w2 is set to 20 mm, for example.
[0015]
That is, the support frame 2 includes the substrate 3, both side plates 4, 4 protruding from both ends of the substrate 3 in the direction of 90 degrees, and both side plates 4, 4 in the vicinity of the substrate 3 and along the substrate 3. A pair of mounting bars 5, 5 arranged so as to connect each other and a pair of mounting bars 5, 5 arranged so as to connect between the protruding ends of both side plates 4, 4. And placement bars 6, 6.
[0016]
A gap 5 a and a gap 6 a are formed between the pair of placement bars 5 and 5 and between the pair of placement bars 6 and 6, respectively.
On the pair of placement bars 5, 5 and the pair of placement bars 6, 6, for example, eleven prismatic slide bodies 7 are placed in parallel and slidable.
[0017]
As shown in FIG. 3, a screw rod 8 protrudes downward on the lower surface side of each slide body 7 at a position corresponding to the gap 5a and gap 6a, and extends downward through the gap 5a and gap 6a. It is designed to protrude. Then, the wing nut 9 is screwed onto the screw rod 8 and tightened to fix the slide body 7 to the support frame 2.
[0018]
FIG. 5 shows a punching device 30 in which the punching male die 11 (or a member configured to enable punching) including the punching pin 12 and the punching female die 1 are combined. The punching male die 11 and the like are lowered by driving by a driving source (not shown) with respect to the paper material 20 placed on the slide body 7 of the punching female die 1, and the punching pin 12, the paper container material 20 is configured to be punched.
[0019]
Next, with reference to FIG. 6, the punching process of the paper container material 20 by the punching apparatus 30 according to the present embodiment will be described.
Two each of the punched portions 20a (shown with cross diagonal lines in FIG. 6) in the paper container material 20 punched in a desired shape placed on the slide body 7 of the female die 1 for punching. Each of the two slide bodies 7 is slid so that the side wall of each slide body 7 corresponds to the both sides of the punched portion 20a, and the wing nut 9 is screwed onto the screw rod 8 and tightened. Thus, the corresponding positioning of each slide body 7 with respect to the support frame 2 and the punched portion 20a is performed.
[0020]
In this state, with respect to the paper container material 20 placed on the slide body 7, the male die 11 for punching (or a member configured so as to be able to punch holes) is driven by a driving source (not shown). The hole is lowered, and the hole punching portion 12a located between the gap 5a and the gap 6a is punched by the hole punching pin 12.
[0021]
Further, when punching another paper container material having a different position and size of the hole punching portion 20a from the paper container material 20, the slide bodies 7 are placed at corresponding positions corresponding to the hole punching portion of the paper container material. Is supported by positioning each slide body 7 in the same manner as described above.
[0022]
Therefore, the hole punching female die 1 and the hole punching device 30 using the hole punching female die 1 according to the present embodiment perform the hole punching for individual paper container materials having different positions and sizes of the hole punching portions. It can be widely used for various paper container materials.
[0023]
According to the female die 1 for hole punching and the hole punching device 30 according to the present embodiment, even when punching the individual paper container materials 20 having different positions and sizes of the hole punching portions, as in the case of the conventional example, the female die each time. There is no need to create a mold, the manufacturing cost of a paper container product such as a cardboard box can be reduced, and the disadvantage of increasing the storage space of a female mold as in the prior art can be eliminated.
[0024]
Of course, the female die for hole punching and the hole punching device of the present invention can be applied not only to hole punching but also to a scrap removing step performed after the hole punching step.
[0025]
【The invention's effect】
According to the first and second aspects of the invention, it is possible to provide a versatile female die for punching that can correspond to individual paper containers with different positions and sizes of the punched portions.
[0026]
According to the invention of claim 3, it is not necessary to make a female mold each time as in the conventional example, the manufacturing cost of paper container products such as cardboard boxes is reduced, and the storage space of the female mold as in the prior art is increased. It is possible to provide a hole punching device that can eliminate the inconvenience.
