The products produced by being crimped such as cornet cone packages, paper cups, paper buckets, etc. are cut by giving the same special shapes in package cutting machines first and then shaped by crimping the specifically shaped package slices.

In the package cutting machines used in the art, package bobbins having a narrow structure are used and specially formed package slices are cut from said narrow package bobbins. The production is limited because of the narrow structure of the package bobbins and the number of cutting machines needs to be increased in order to improve the production capacity. This requires considerable investments and additional space in the production area and increases the energy and labor expenditures. In addition to the mentioned disadvantages, the cutting procedure may not be carried out properly due to reasons such as the folding or slipping of the package in the present cutting machines. This causes wastage and production costs to increase. Therefore, in the known state of the art, there is a need for a machine which makes proper cuts from broad sized package bobbins.

In this detailed description the preferred alternatives of the package cutting machine of the invention are described only for a better understanding of the subject and in the way to create no limiting effect whatsoever.

In Figure 1, representative view of the package cutting machine of the invention has been given. Accordingly, the package cutting machine basically comprises a lower opening cylinder (10) and an upper opening cylinder (20) which opens the package from the package bobbin (300), a bobbin sensor (30) which adjusts the opening speed of the package bobbin (300), a lower stretching cylinder (40) which passes the package opened from the package bobbin (10) from under and stretches the same, an upper stretching cylinder (50) which passes the package opened from the lower stretching cylinder (40) from above and stretches the same, a lower straightening cylinder (70) which passes the package from the upper stretching cylinder (50) from under and straightens the same, an upper straightening cylinder (80) which passes the package from the lower straightening cylinder (70) from under and straightens the same, a final straightening cylinder (90) which passes the package from the upper straightening cylinder (80) flat from under and straightens the same, a flattening cylinder (100) which flattens the package passing from the final straightening cylinder (90), a dynamic cylinder (110) which moves up and down, providing that the packages from the flattening cylinder (100) are transferred at certain intervals, a compression cylinder (120) which presses the package from the dynamic cylinder (110) and prevents the same from rising and provides that it remains stretched, a stretcher sensor (130) which measures the stretch of the package passing from the compression cylinder (120), a final feeding cylinder (170) which transfers the package passing from the dynamic cylinder (110), a flatness sensor (160) which controls the flatness of the package passing from the final feeding cylinder (170), a slicing press (180) with back-and-forth motion which cuts the package transferred from the final feeding cylinder (170) and turns it into specially formed package slice (302), a press guide (190) bearing the back-and-forth motion of the slicing press (180), a press movement arm (200) which is connected to the slicing press (180) by means of the press movement joint (210) and moves the slicing press (180) back and forth on the press guide (190), a press motor (230) which is connected to the press movement arm (200) by means of the rotational disk (220) and which drives the press movement arm (200) with the rotational movement, a side package holder (240) and a lower package holder (250) which hold and stack the specially formed package slices (302) obtained on the slicing press (180), a package compressor (260) which press the specially formed package slices (302) on the side package holder (240) and the lower package holder (250), a package slice stop (270) which prevents the specially formed package slices (302) from bulging out over the side package holder (240) and lower package holder (250), and a wire grid (280) which provides that the package descending to the slicing press (180) from the final feeding cylinder (170) is observed.

The package cutting machine according to the invention provides for the production of specially cut package slices (302) with a cutting procedure from the package bobbin (300). As seen in Figure 2, the package on the package bobbin (300) connected to the package cutting machine is separated and opened from the package bobbin (300) by means of the lower opening cylinder (10), and the first stretch is provided by means of the upper opening cylinder (20). On the upper opening cylinder (20), there is at least one bobbin sensor (30). The bobbin sensor (30) adjusts the opening speed of the package bobbin (300) depending on the diameter of the package bobbin (300).

The package from the lower stretching cylinder (40) is passed over the upper stretching cylinder (50) and passed under the lower straightening cylinder (70) and is transferred to the upper straightening cylinder (80). There is an edge control sensor (60) which controls the edges of the package on the upper stretching cylinder (50). The stretched package (301) from the upper straightening cylinder (80) is transferred to the flattening cylinder (100) with the final straightening cylinder (90). The package from the flattening cylinder (100) arrives at the dynamic cylinder (110) which moves up and down. The dynamic cylinder (110) provides that the continuous package transfer is carried out for slicing at certain intervals. For this purpose, the dynamic cylinder (110) moves up and down by means of a movement piston (150) on a cylinder rail (140). The dynamic cylinder (110) is connected on said cylinder rail (140) and the movement piston (150) moves the cylinder rail (140) up and down.

An inward compression cylinder (120) is positioned on the dynamic cylinder (110). Said compression cylinder (120) presses the package passing through the dynamic cylinder (110) and prevents it from rising, providing that it remains stretched. The stretch of the package passing from the compression cylinder (120) is measured by means of the stretcher sensor (130) positioned on the compression cylinder (120). Passing from the dynamic cylinder (110), the package is transferred to the slicing press (180) by means of the final feeding cylinder (170). Descending from the final feeding cylinder (170) to the slicing press (180), the package can be observed from the wire grid (280) located between the final feeding cylinder (170) and the slicing press (180).

The flatness of the package passing from the final feeding cylinder (170) is controlled by means of the flatness sensor (160) positioned on the final feeding cylinder (170).

The slicing press (180) with back-and-forth motion cutting the package transferred from the feeding cylinder (170) and turning the same into a specially formed package slice (302) is carried on the press guide (190) and its back-and-forth motion on said press guide (190) is provided.

For the back-and-forth motion of the slicing press (180), a press movement arm (200) is connected to the slicing press (180) by means of the press movement joint (210). Said press movement arm (200) is connected on the other end to the distal point from the rotational disk (220) on a press motor (230) which makes a rotational movement. Thereby, it is provided that the rotational disk (220) rotates with the rotational movement of the press motor (230) and makes a back-and-forth motion with the press movement arm (200) being driven.

The specially formed package slices (302) obtained on the slicing press (180) are stacked by being held by means of the side package holder (240) and lower package holder (250) located at the rear side of the slicing press (180). In the meantime, the waste packages (303) from the specially cut package slices (302) are transferred out from the package cutting machine in order to be reused.

There is a package compressor (260) on the side package holder (240) and the lower package holder (250). Said package compressor (260) presses the specially formed package slices (302) on the side package holder (240) and lower package holder (250). At the same time, there is a package slice stop (270) on the side package holder (240) and the lower package holder (250). Said package slice stop (270) prevents the specially formed package slices (302) from bulging out over the side package holder (240) and lower package holder (250). The specially formed package slices (302) stacked on the side package holder (240) and lower package holder (250) are held in order with the package compressor (260) and stacked to the package slice stop (270).

The working principle of the package cutting machine according to the invention is as follows;

The package on the package bobbin (300) connected to the package cutting machine is separated and opened from the package bobbin (300) by means of the lower opening cylinder (10) and the first stretch is provided by means of the upper opening cylinder (20).

The package from the lower stretching cylinder (40) is passed over the upper stretching cylinder (50) and passed under the lower straightening cylinder (70) and the stretched package (301) which is passed from the upper straightening cylinder (80) is transferred to the flattening cylinder (100) with the final straightening cylinder (90). Arriving from the flattening cylinder (100), the package is transferred to the slicing press (180) by means of the final feeding cylinder (170) by leaving a margin for the package in the dynamic cylinder (110) and cut into a specially formed package slice (302).

The specially formed package slices (302) obtained on the slicing press (180) are stacked by being held by means of the side package holder (240) and lower package holder (250) located at the rear side of the slicing press (180). The specially formed package slices (302) stacked on the side package holder (240) and lower package holder (250) are held in order with the package compressor (260) and stacked to the package slice stop (270). The waste packages (303) left from the specially cut package slices (302) are transferred out in order to be reused.
