Description

Scrap remover for Die Cutting}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scrap remover of die cutting, and more particularly, to a scrap remover of die cutting in which a plurality of exploded views are configured to easily remove scraps by fixing and cutting a portion and then separating and transporting the die cut disc. .

In modern times, many products are pouring out, varying in size and shape. Accordingly, packaging boxes for packaging them also vary in shape and size. Most packaging boxes are made of cuboids and have a structure in which a product is placed. Such a packaging box is usually made by cutting a flat raw material such as thick paper into a development view to fold it to make a packaging box.

Here, the thomson knife cuts this planar raw material into a flat pattern. Once the size of the packaging box is determined, draw a development plan according to its shape and size, and insert a Thomson knife into the wooden board according to the completed development plan to complete the preparation. When a raw material is taken with a wooden board where such a thomson knife is installed, the raw material is cut in the shape of the developed view. This operation is commonly called die cutting.

Referring to FIG. 1, an example of a developed view for configuring a packaging box is shown. These developments are generally die-cut in a single disc, and these discs are stacked one by one. The disks stacked by die cutting are arranged by a worker using a hammer.

However, as shown in FIG. 2, since a plurality of developed views must remain attached to each other, the cut lines dividing the partitions are not completely cut, but are partially attached to each other. In the cleanup work, the worker cleans up manually, but in some cases it is easy to clean up, but when dozens or hundreds of discs accumulate, this manual work is not only very demanding but also almost impossible.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems of the prior art, and provides a scrap remover of die cutting, which is configured to facilitate work by cutting and separating the original plates cut and stacked by a thomson knife. There is a purpose.

The scrap remover of the die cutting according to the present invention is a frame shelf in which the developed die-cut disks are stacked and raised, a press that descends from the frame shelf to press the disks, and a portion of the disks is moved and fixed by the fixed press. It characterized in that it comprises a separating shelf to move up and down from the frame shelf in a state to separate a portion of the disc.

Here, the frame shelf is characterized in that the cutting knife is installed to cut a portion of the disc while moving up and down.

Since the scrap remover of the die cutting according to the present invention separates a part of the developed view, the operator can easily separate the completed developed view to provide an effect of completing the product.

1 is a plan view showing an example of a general development view,
2 is a plan view showing an example of a general development disc;
3 is a plan view showing a state in which separation occurs along the perforation line in a general development view disc;
4 is a front view of a state in which a disc is supplied to the scrap remover of die cutting according to the present invention and the work is progressed by a cutting knife;
5 is a front view of a state in which the development disc is fed in the die remover scrap remover according to the present invention and fixed by presses at a predetermined position;
6 is a front view of a state in which separation occurs while a portion of the die-cut scraper according to the present invention moves upward and downward in a fixed state of the original plate fixed;
FIG. 7 is a front view of a state in which separation occurs while a part of the scrap plate remover of the die cutting according to the present invention is moved left and right in a fixed state of the original plate.

The scrap remover of die cutting according to the present invention will arrange the original plate 10 in which a plurality of developed views are die cut according to the developed view 1 shown in FIG. 1. The scrap remover of die cutting according to the present invention is shown in FIG. 4. As shown, the die cutting scrap remover cuts a portion of the accumulated disc 10, then moves to fix it, and then moves the portion up and down to allow separation along the perforation line 10a. .

4 to 6, the scrap remover of die cutting according to the present invention includes a frame shelf 20 on which the stacked discs 10 are placed. The frame shelf 20 supports all the parts, on which the discs 10 are placed and moved for cleaning.

The upper part of the frame shelf 20 is provided with a cutting knife 61 for cutting a portion of the disc (10). The cutting knife 61 is provided with a cylinder 60 at the top to move up and down by pneumatic or hydraulic. When the cutting knife 61 moves up and down each time the disks 10 are supplied, the groove 10b is dug at the end of the cutting line 10a, as shown in FIG. 3, along the cutting line 10a. Separation of the development can occur. Therefore, when the discs 10 are stopped at each cutting line 10a position and the cutting knife 61 descends and rises, the developed views are separated as shown in FIG. 3. However, this does not mean complete separation along the perforation line (10a). This is because, although not shown in the drawings, very fine parts are attached to each other. This is because when a part of the thomson knife, for example, about 1 mm is dug, the incision is not made. This allows the development to proceed without completely separating each other. Therefore, this part is still attached.

A fixing press 51 is installed at the rear of the cutting knife 61 to press and fix the discs 10 on the frame shelf 20. The fixed press 51 is moved up and down by the upper cylinder 50. When moved to the bottom to press the disk 10 is fixed, and to return to the original position to the top to release. Therefore, the fixed press 51 serves to fix the disc 10 on the frame shelf 20.

A separating shelf 30 is provided behind the fixed press 51. As shown in FIG. 6, the separation shelf 30 is installed to be movable in the up and down direction relatively to the upper part of the frame shelf 20, and a cylinder 31 is installed at the bottom thereof so that the separation shelf 30 is up and down. Move it. This cylinder 31 can also be made to move up and down quickly by moving up and down. Of course, instead of the cylinder 31, other vibration means may be installed to cause vibration.

The upper part of the separation shelf 30 is provided with a moving press 41 configured to move up and down together with the separation shelf 30 and move itself up and down again. The cylinder 40 is installed in the upper part of the moving press 41, and raises and lowers the moving press 41. As shown in FIG. The moving press 41 presses the discs 10 while moving up and down similarly to the fixed press 51.

In addition, a transfer mechanism 70 is installed inside the separation shelf 30 to return the pushed back disc 10 in a planar direction rather than in a vertical direction. Although not shown, the transfer mechanism 70 may be configured to be driven in a straight line along the rail.

Referring to FIG. 4, when a predetermined amount is accumulated in the developed disc 10 cut by the Thomson knife, an operator places the upper portion of the frame shelf 20. Then, when the disc 10 is pushed to a predetermined position according to the guide, the cutting knife 60 comes down according to the operation of the cylinder 60, and stops at each cutting line 10a position and is cut by the cutting knife 61. Is done.

Referring to FIG. 5, when a cut is made on the side of the disc 10, a part of the disc 10 is placed on the separating shelf 30. At this time, when the presses 41 and 51 are lowered, the disc 10 is fixed. As shown in FIG. 6, when the separating shelf 30 is moved up and down once in the fixed state, as shown in FIG. Likewise, separation of the original plate will occur. That is, the separation is completely along the cut line (10a). In this manner, the disc 10 is separated, and when the transfer mechanism 70 returns the disc 10 to its original position, the worker transfers the separated disc 10 from the frame shelf 20 to proceed with other work. .

Another embodiment according to the invention is shown in FIG. 7. As shown, the cylinder 80 and the rod 81 are installed at the rear of the separation shelf 30 to push the separation shelf 30 to the left and right. Naturally, such a conveying means may be installed and used in the front and rear directions when viewed from the drawing. It is also possible to provide other means other than the cylinder rod, for example, a rotating cam to contact the separating shelf and to return to the spring to quickly vibrate. In this way, the cut is made quickly along the cut line.
