Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winder apparatus for continuously changing the frame of a paper machine or a smearing machine without breaking the paper. 2. Description of the Related Art A conventional winder device will be described with reference to FIG. 1. A winding device 1 for winding manufactured paper, a reel drum 2 for rotating the winding by surface pressure, and A spool 4 that stands by as a core for winding and a cut knife 3 that is activated by a frame change signal immediately before the reel drum 2
(One or several are provided.) In general, a winder device is configured from the air ejection device 5 to peel off the paper from the reel drum 2 at the same time. Conventionally, when changing the frame, the winding 1 is replaced by the reel drum 2
When the frame is approaching, the spool 4 serving as a core for the next winding which is waiting on the reel drum 2 is rotated, and the reel drum 2 and the front of the reel drum 2 are rotated. On the way to the paper roll 7, the cut knife 3, which cuts the paper at right angles to the flow of the paper, is actuated simultaneously with the frame change signal to cut the paper. At the same time, air is jetted from the air jetting device 5 toward the spool 4 from behind the spool 4 toward the spool 4, the paper is peeled off the reel drum 2, and the paper is wound around the spool 4 to change the frame. Has been implemented. However, when the next spool 4 winds the paper, air is trapped in the wound paper due to the entrainment of air by the rotation of the air ejecting device 5 and the spool 4, which causes wrinkles to enter the paper as it is. Are rolled up, so that many poorly wound products are manufactured under the influence of wrinkles. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and eliminates the incorporation of air into the lower winding immediately after a frame change, thereby reducing the occurrence of lower winding wrinkles and lower winding broke. The purpose is to prevent and improve the product yield. According to the present invention, there is provided a reel drum 2 which applies pressure to a winding 1 by a surface pressure to transmit rotation, and which operates at a frame change signal at the time of frame change and is perpendicular to the paper flow direction. to the cutting knife 3 to put cuts in the paper, in a winder apparatus having an air injection device 5 for waiting above the cut knife 3 actuated after the reel drum 2 winds the paper to the next spool 4, the cutting knife 3 At the same time as the frame change signal
Activate to scratch the paper and at the same time
The paper is wound around the next spool 4 and immediately thereafter,
A winder device comprising a vertically movable cutting knife 6 for making a cut in front of the cutting knife 3 in parallel with the paper flow direction. A cut is made in parallel with the flow of the paper with a cutting knife 6 for removing wrinkles for winding the reeler provided in front of the reel drum 2, and the air taken in at the time of lower winding of the new spool 4 is cut into the paper. Because of the escape, the generation of wrinkles in the lower winding can be prevented, thereby reducing the occurrence of broke in the lower winding. Hereinafter, the present invention will be described in detail with reference to the drawings, but it is needless to say that the present invention is not limited thereto. First Embodiment A winder device according to the present invention comprises a winding device 1 for winding a manufactured paper, a reel drum 2 for rotating the winding device by surface pressure, and a standby unit above the winding device to become a core for the next winding operation. The cutting knife 3 # (one or several provided) is operated immediately before the spool 4 and the reel drum 2 by the frame change signal, and the air ejection device 5 for simultaneously peeling the paper from the reel drum 2 The knife 3 is provided with a vertically movable cutting knife 6 for making a cut in front of the knife 3 in a direction parallel to the paper flow direction. Next, a method of operating the winder device of the present invention will be described. Normally, the paper passes through the reel drum 2, comes into surface contact with the reel drum 2, and is wound up by the take-up 1 by pressurization. When the winding diameter of the winding 1 reaches a predetermined size, the new spool 4 waiting on the reel drum 2 descends while rotating and comes into contact with the reel drum. On the way between the reel drum 2 and the paper roll 7 in front of the reel drum 2, the cut knife 3, which cuts the paper at a right angle to the flow of the paper, is operated at the same time as the frame change signal to damage the paper. At the same time, air is jetted from the air jetting device 5 toward the spool 4 from behind the spool 4 toward the spool 4, the paper is peeled off from the reel drum 2, and the paper is wound around the spool 4. Immediately thereafter, the cutting knife 6 which can be moved up and down, which is provided in front of the cutting knife 3, is raised to make a cut in the flow direction on the paper. The length of the cut is preferably within 1 m in consideration of the risk of an increase in the number of breaks due to the cut and the risk of paper breakage. However, taking into account the speed of the machine and the like, the rise of the cutting edge may be adjusted to about 1 to 3 seconds. The notched portion allows the air entrapped in the lower winding to escape, so that it is possible to prevent the lower winding wrinkles caused by the air entanglement and the lower winding broke caused by the wrinkles. The direction in which the cutting knife 6 enters the paper may be vertical or oblique, but it is preferable that the cutting knife 6 protrudes upward from below for convenience of maintenance. However, the blade of the cutting knife 6 is always set in parallel with the flow of the paper.
It is not preferable to extend the knife blade at right angles to the paper flow direction, as this may cause paper breakage. The installation location of the cutting knife 6 in the paper width direction is preferably at the center. However, since the lower wrinkle due to the entrainment of air does not always occur at the center, it is necessary to provide a moving device for the cutting knife manually or automatically. ,
It is also possible to provide a plurality of cutting knives in the width direction and make a cut only at the portion where air is involved. The incision knife elevating device is preferably of a cam type in order to make a series of up and down movements, but the structure of the device is not limited, such as directly connecting an air cylinder. The shape of the cutting edge of the cutting knife 6 is preferably a single-edged one which is angled with respect to the flow of the paper, since the cut edge becomes sharp. However, the use of a double-edged knife or a disk-shaped rotary knife is preferred. It does not limit the shape. As described above, the present invention has the effect of eliminating the occurrence of lower winding wrinkles and breaks due to air entrainment.
