JP 2011-235491 A

By the way, on a continuous medium, different types of label images such as size and shape may be printed for each width direction (row).
However, when different types of label images are printed in multiple rows on a continuous medium, the image is cut into a desired shape with a cutter to remove unnecessary portions, cut with a slitter for each row, and wound with a rewinder. However, since the area occupied by the label image is different for each row, the thickness of the portion where the continuous media overlap when wound by the rewinder is not uniform, and the roll diameter may be different for each row. .
For example, when a large label image and a small label image are printed on the same continuous medium for each column, the column on which the large label image is printed has many necessary portions (label base materials) remaining on the continuous medium as label images. Therefore, when the continuous medium is wound around the rewinder, the thickness is increased and the roll diameter is increased. On the other hand, in the row where the small label image is printed, there are few necessary portions remaining on the continuous medium as the label image. The thickness is small and the roll diameter is small compared to the line on which the image is printed, and the difference in the roll diameter increases as the amount of winding increases.
When the difference in roll diameter is increased for each row, if the rotation amount of the rewinder is the same as in the conventional case, a difference for each row is generated in the amount that can be wound in one rotation. At this time, since the speed at which the continuous medium is conveyed to the rewinder is constant, if there is a difference in the amount that can be wound for each row, extra slack may occur between the slitter and the rewinder, There is a possibility that the winding density may be different from one to another, so that inconvenience occurs in winding, and as a result, the quality of the label product may be deteriorated.

  Therefore, the present invention has been made in view of the above-described problems, and an object of the present invention is to print different types of images for each column on a continuous medium, perform cutting and scraping, and perform predetermined processing for each column. A cutting device capable of suitably winding each of the continuous media wound around the rewinder for each row even when the roll diameter of the continuous media is different for each row when winding with a rewinder after slitting with a width. It is to provide a cutting method.

According to the cutting device of the present invention, the problem is that a continuous medium having a base material layer on which a plurality of types of images are formed in the width direction and a release layer attached in a state where the base material layer can be peeled off. A conveying means for conveying; a cutting means for cutting the continuous medium conveyed by the conveying means into a desired shape; and for the continuous medium cut to a desired shape by the cutting means, the release layer and Separating means for separating an unnecessary part other than a necessary part composed of at least the region including the image from the release layer and separating the substrate from the continuous medium, and separating the unnecessary part by the separating means The slit means for continuously cutting the continuous medium in the longitudinal direction with a predetermined width for each type of image, and the continuous medium separated by being continuously cut in the longitudinal direction by the slit means, respectively. Comprising of a winding means for winding on the rotating shaft, and control means for controlling the means taken the winding, the said winding means constitute the necessary portions in accordance with the type of the image to each of the rotary shaft The continuous medium having a different area of the base material layer is wound up, and the control means, when a difference occurs in the roll diameter of the continuous medium having a different area of the base material layer wound up for each of the rotating shafts This is solved by changing the rotational speed of the rotary shaft for each rotary shaft in accordance with the roll diameter.
Further, according to the cutting method of the present invention, a continuous medium having a base material layer on which a plurality of types of images are formed in the width direction and a release layer attached in a state where the base material layer can be peeled is conveyed. A conveying step; a cutting step for cutting the continuous medium conveyed in the conveying step into a desired shape; and the continuous medium cut in a desired shape by the cutting step. A separation step of separating unnecessary portions other than a necessary portion consisting of at least the region including the image in the material layer from the release layer and separating the unnecessary portions from the continuous medium, and the continuous medium in which the unnecessary portions are separated by the separation step The slit process for continuously cutting in the longitudinal direction with a predetermined width for each type of image, and the continuous medium separated by being continuously cut in the longitudinal direction by the slit process, respectively. A winding step of winding the shaft, is executed, and the winding process is the continuous medium in which the area of the base layer is different constituting the necessary portions in accordance with the type of the image to each of the rotary shaft When the roll diameter of the continuous medium having a different area of the base material layer wound up for each rotation shaft is different , the rotation speed of the rotation shaft is set according to the size of the roll diameter. It is solved by changing separately.

  As in the above configuration, the continuous media that are continuously cut and separated in the longitudinal direction by the slit means are wound on the respective rotating shafts, and the roll diameter of the continuous media wound for each rotating shaft is set. Even if there is a difference in roll diameter when winding a continuous medium on which images of different types such as size and shape are printed for each row by changing the rotation speed of the rotation shaft for each rotation shaft accordingly Further, the continuous medium can be suitably wound up without causing excessive slack between the slit means and the winding means, or without different winding density for each column having different image types.

At this time, it is preferable that the control means changes the rotation speed based on a tension of the continuous medium or a physical quantity that changes in accordance with the tension.
As in the above configuration, by changing the rotation speed for each rotation axis based on the tension generated in the continuous medium between the slit means and the winding means (rotation axis) or the physical quantity changing according to the tension, Since the tension of the continuous medium can be always constant, the continuous medium can be wound more suitably. In addition, as a means to change the rotational speed here, a torque limiter etc. are applicable, for example.

At this time, it is preferable that the winding means arranges the rotating shaft at a position having a relatively different height.
By arranging the rotating shafts of the winding means at different heights as in the above configuration, the continuous medium continuously cut by the slit means is wound up and down, so that adjacent continuous media It is possible to prevent the cut end faces from coming into contact with each other and prevent the cut end faces from rubbing against each other.
Further, after the winding is completed, when each continuous medium (label product) is pulled out in the direction of the rotation axis and taken out, the taking out operation becomes easy.

At this time, it is preferable that a guide roller or a shaft that contacts the continuous medium and changes the conveying direction of the continuous medium is provided between the slit means and the winding means.
As described above, by arranging a guide roller, a shaft or the like that changes the conveying direction of the continuous medium between the slit means and the winding means, the winding amount of the continuous medium wound on the winding means can be reduced. Even when the roll diameter increases and the roll diameter increases, the discharge angle of the continuous medium discharged from the slit means can be made constant at all times, and highly accurate slitting can be realized.

  According to the cutting apparatus and the cutting method of the present invention, different types of images are printed on a continuous medium for each column, cut and scraped, and slit processing is performed with a predetermined width for each column, and then wound by a rewinder. When taking, even if the roll diameter of the continuous medium wound around the rewinder is different for each row, each can be suitably taken up.

The rotational speeds of the rotary shafts 17 and 18 are changed based on the tension of the continuous medium 30 (label products 40a and 40b) stretched between the slit cut portion 8 and the physical quantity corresponding to the tension. Thus, the tension is kept constant. That is, since the tension of the continuous medium 30 (label products 40a and 40b) is kept constant by this torque limiter, the roll diameter of the continuous medium 30 (label products 40a and 40b) wound around the rotary shafts 17 and 18 is large. Accordingly, the rotational speeds of the rotary shafts 17 and 18 can be individually changed.

In this embodiment, the first label product take-up unit 9 Is disposed at a relatively higher position than the second label product winding unit 10. Thus, by arranging the rotation shaft 17 of the first label product winding unit 9 and the rotation shaft 18 of the second label product winding unit 10 not on the same axis but at different heights, the slit cut unit 8 is arranged. It is possible to prevent the cut end faces of the label products 40a and 40b discharged after being cut more continuously from coming into contact with each other and being rubbed and worn. Further, when the label products 40a and 40b are taken out after the winding is completed, the taking-out operation becomes easy.

In the present embodiment, the continuous medium 30 (label products 40a and 40b) is transported between the first label product winding unit 9 and the second label product winding unit 10 and the slit cut unit 8 in the transport direction. Are provided with two turning rollers 19 and 20 that rotate in accordance with the movement.

Similarly, the turning roller 20 contacts the back side of the label product 40b discharged from the slit cut portion 8 to change the conveyance direction of the label product 40b.
As shown in FIG. 5, the continuous rollers 30 (label products 40 a and 40 b) wound around the first label product winding unit 9 and the second label product winding unit 10 are wound by the turning rollers 19 and 20. Even when the amount is increased and the roll diameter is increased, the discharge angle α between the label product 40a and the label product 40b discharged from the slit cut portion 8 can always be kept constant, so that the accuracy is high. Slit processing can be realized.
In the present embodiment, the roller is used. However, a shaft or the like may be used instead of the roller as long as the conveyance direction can be changed.
