Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for cutting whole paper, which comprises an upper active die and a lower die with a passive counterpart, the upper die Consists of a frame and a supporting plate supporting the punching and grooving blades, the supporting plate is supported in the frame by adjusting and supporting screws, the lower mold consists of a metal plate and the upper mold And an apparatus provided with an abutment member for positioning the lower mold.

[0002]

BACKGROUND OF THE INVENTION In a cutting robot for processing paperboard, work is done using an upper active die with punching and grooving blades and a lower die supporting a passive counterpart. ing. These active and passive types are
Through the fixed abutment member, it must be precisely positioned and fixed on the cutting table so as to be precisely aligned during the cutting process.

The lower passive mold has as its foundation a precisely fixed steel plate, so that a correct positioning is possible without problems. The upper mold is
It has a steel frame, and inside this frame,
A wooden plate with tensioning blades is tensioned by adjusting screws. In this case, the frame is positioned very accurately by the abutment members, but the wooden plate cannot be tensioned in the frame in a correct arrangement, so that it is not possible to bring the upper and lower molds into precise alignment. It's not easy. Usually, such drawbacks first occur at the beginning of the manufacturing process.

Heretofore, the frame has heretofore been pulled out of the device and the support plate in the frame can be repositioned through about 20 adjusting screws. Then, regardless of whether or not the defect was removed, the frame was pushed into the apparatus again and fixed for a new cutting process. In some cases, the work is
It had to be repeated often. Adjusting the support plate with an adjusting screw is cumbersome and time consuming for the following reasons. Ie about 2
Zero adjusting screws must be adjusted, the total tightening force by the screws must be large enough to ensure that the mold is tensioned and secured in the frame, and the mold is stretched on three sides. By being pressed inward from the corners, and the template may be weakened by multiple cutting actions by the blade, allowing it to easily pass through the blade.

According to another known solution, the lower mold is adjusted in position by means of an adjustable abutment arranged behind the upper tool.

However, this requires an intermediate part between the lower mold and the cutting table, which intermediate part must be able to be removed from the device together with the lower mold. This allows the abutment member arranged in this intermediate part to be adjustable. According to this solution, the flow of the whole paper has to be adapted to the changed tool position throughout the machine.

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to solve the above drawbacks of the prior art, or
It is an object of the present invention to provide a device in which the positioning is made substantially easy and thus a quick and accurate positioning is achieved.

[0008]

In order to solve the above-mentioned problems, according to the present invention, there is provided an apparatus for cutting whole sheets, which comprises an upper active die and a passive counterpart. A lower mold, wherein the upper mold comprises a frame and a support plate for supporting the punching and grooving blades, the support plate being supported in the frame by adjusting and supporting screws, The lower mold is made of a metal plate and is provided with a contact member for positioning the upper mold and the lower mold, wherein the contact member is the upper mold and / or the lower mold. An apparatus is constructed which is characterized in that it is adjustable for the positioning of the mould.

According to a preferred embodiment of the invention, the adjustment of the abutment member is done manually through the operating element.

According to another preferred embodiment of the invention, the adjustment of the abutment member is made by motor drive.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, numeral 1 indicates the upper active mold with punching and grooving blades 2, and numeral 3 indicates the lower passive mold with its counterpart 4. There is. Both of these types 1
And 3 are fixed on the cutting tables 5 and 6, respectively, and are positioned with respect to each other by stationary contact members 10, 11, 12, 13.

The number 8 represents a support pretote.
The support plate 8 is fixed in tension in the frame 7 by means of adjustment and support screws 9 and roughly positioned. And the accurate adjustment is made by the contact member 1.
This is done through adjustments of 1, 12, and 13.

According to the invention, the final fine adjustment of the frame is divided into positioning in two parts. The support plate 8 is roughly positioned in the frame 7 and is fixed in a stretched state at an appropriate angle by an optimum force. If the tool reaches the device, this process is complete.

The support plate 8 and the frame 7 are fixed to the upper surface of the cutting table by an element (not shown) as in the conventional case. If both molds 1 and 3 do not match, the already fixedly arranged abutment members 11, 12, 13 with respect to the schematically illustrated frame are repositioned, thereby aligning the mold positions. To be
This adjustment can be done manually or by motor drive.

Through adjustment of the abutment member 12, the mold is moved to the shaft 1
The positions are displaced so as to cross the direction along the lines 1 and 13.

If the abutment members 11, 13 are displaced by the same amount, the mold is displaced in the direction along the axes 11, 13 or in the opposite direction. Abutting member 1
By individually adjusting 1, 13 the mold can be twisted around the respective rotation axes 11-13 in each case. The adjustment range is ensured to meet the site requirements.

Thus, according to the invention, the mold no longer has to be removed from the device for positioning. This is because the three operating elements are always provided by the operating surface for adjusting the abutment member.
When correction is made, the support plate is optimally stretched over the frame. Instead of about 20 adjusting screws,
Only the three abutment members need to be adjusted.

The adjustment of the abutment member is extremely easy and is made accurately by the scale. With respect to the cut product, the measured error is immediately transferred to the abutment member, so that a satisfactory correction is made.

It is not necessary to control the flow of whole paper in the device. This is because the correction is made on the part that causes the inaccuracy.
