Description

  TECHNICAL FIELD The present invention relates to a winder device that rewinds a winding paper manufactured by a paper machine into a small width winding, and in particular, a winding end side of a completed small winding and a winding start side of a small winding to be formed next. The present invention relates to a winder winder device that cuts between the two and reliably separates them.

  Paper manufactured by a paper machine is wound around a machine reel and formed into a winding, but the manufactured winding is supposed to have a large width in order to increase production efficiency. On the other hand, consumers such as newspaper companies, printing companies, and packaging material companies do not have machinery that handles wide and large-diameter windings, and even paper mills handle wide windings. Hateful. For this reason, in a paper mill, a take-up taken up by a machine reel of a paper machine is processed into a take-up with an appropriate width and diameter according to the machine capability of a printing machine etc. owned by a customer, It is cut into flat paper of the size and shipped.

  When a wide winding taken up on a machine reel is subjected to a winder device to be reshaped into a small winding, the paper sheet cut into a small width by a slitter knife is wound around a core paper tube to obtain a small width. It becomes a small winding. In the winder device, an appropriate number of paper tubes are set in the axial direction in order to take up the cut paper sheet, and the paper sheets are wound around the paper tubes individually. At this time, if the leading end of the paper sheet cut to a small width is not securely held by the paper tube, the leading end of the paper sheet is lifted from the paper tube and the winding is not tightly wound. In addition, there is a possibility of interfering with a paper sheet wound up adjacently. For this reason, it is necessary to securely hold the leading end portion of the paper sheet on the paper tube, and the leading end portion of the paper sheet is stuck to the paper tube with a double-sided adhesive tape in order to hold the lower winding for winding.

  For example, FIG. 4 shows a schematic structure of a center drum type winder device 1, and a paper sheet S of winding paper is cut from a reel (not shown) at a predetermined position in the width direction by a slitter knife 6, and is then applied to the winder drum 2. Have been fed. The paper sheet S is guided to the winder drum 2 while winding a part of the winder drum 2, and a small small winding R is wound around a paper tube (not shown). In the center drum type winder device 1, the small windings R are formed side by side along the axial direction of the winder drum 2, or are formed at positions shifted at an appropriate angle in the circumferential direction of the winder drum 2. You can do it. When the small winding R is formed by winding up to a predetermined length, the next paper tube is set and a new small winding R is formed. At this time, it is necessary to cut between the winding end side, which is the rear end of the formed small winding R, and the winding start side, which is the leading end of the next small winding R to be formed. At this time, a double-sided adhesive tape is attached to these parts to be cut, and the paper sheet S and the double-sided adhesive tape are cut together. After that, the double-sided adhesive tape separated at this cutting part and adhered to the winding tail side is adhered to the outer winding of the completed small winding R, and the double-sided adhesive tape adhered to the winding start side is formed next. In order to form the lower winding of the small take-up R, it is adhered to the paper tube. For this reason, the winder device 1 is provided with a tape applying device 3 and a cutter.

  FIG. 5 is a schematic plan view showing the tape applicator 3. The imaginary line on the drawing shows the tape applicator 3 in the application position, and the solid line shows the condition in the preparation position. Moreover, FIG. 4 has shown the state which has the tape sticking apparatus 3 in a sticking position. The tape applicator 3 includes a tape reel 3a on which a double-sided adhesive tape is wound, a release paper take-up reel 3b that takes up release paper peeled off from the double-sided adhesive tape, and a paper sheet together with the applied tape. A cutter 4 is provided. The tape applicator 3 is movably attached to a guide rail 5 disposed along the axial direction of the winder drum 2. 4 is configured to rotate in the counterclockwise direction in FIG. 5 to the application position with the vertical direction as an axis. Then, by running while being guided by the guide rail 5, the double-sided adhesive tape is adhered to the paper sheet S previously cut into the width of the small winding R and wound around the winder drum 2. Then, the stuck double-sided adhesive tape and the paper sheet S are cut by the cutter 4.

  Further, depending on the type of the winder device, for example, as disclosed in Patent Document 1, there is a structure in which a double-sided adhesive tape is attached to a paper tube.

Japanese Patent Laid-Open No. 4-12962

  FIG. 6 shows a cutting unit M that combines a paper sheet S disposed on the outer peripheral surface of the winder drum 2 and a double-sided adhesive tape T attached to the paper sheet S by the cutter 4 traveling in the direction of the arrow P in the figure. Shows the state of cutting. Incidentally, an appropriate number of grooves 2a are formed in the circumferential direction of the winder drum 2 in the circumferential direction so that air attached to the paper sheet S can escape from between the paper sheet S and the winder drum 2. However, even when the cutter 4 passes through the portion facing the groove portion 2a, there is a possibility that the uncut portion U is generated without being cut at this portion, and the cut portion M becomes perforated.

  When the uncut portion U is generated, the separation between the winding end side and the winding start side cannot be performed smoothly, and the completed small winding R is discharged and the leading end of the paper sheet S is attached to the paper tube. Therefore, the winder device 1 must be stopped.
