Scratches due to contact with rails are eliminated, and contact resistance between the lower surface of the take-up material and the upper surface of the transport rail is eliminated when contacting the fixed material guide when the transport line is regulated. It is an object of the present invention to provide a winding device that can suppress the occurrence of defects and reduce the occurrence of defects in the characteristics of the winding element due to scratches in the winding material or the entrainment of dust.

  In order to achieve the above object, the present invention has the following configuration.

  The invention described in claim 1 of the present invention particularly has a plurality of small diameters formed along the transport direction on the lower surface side of the winding material on the transport path of the strip-shaped winding material supplied in a reel shape. By providing a transport rail for ejecting a fluid such as air from the hole and floating the winding material, it is possible to eliminate scratches due to contact with the transport rail during the winding operation. In addition, there is no contact resistance between the lower surface of the winding material and the upper surface of the conveyance rail when contacting the upper surface of the conveyance rail and the fixed material guide that regulates the conveyance line provided along both sides of the winding material. This reduces the contact stress and suppresses the generation of dust due to the removal of cutting burrs, etc. that occur when taking up the material on the side of the winding material. It has the effect that generation | occurrence | production of can be reduced.

  As described above, the winding device of the present invention ejects a fluid such as air from a plurality of small-diameter holes formed in the conveyance rail, and floats the winding material, so that the winding device is in contact with the conveyance rail during the winding operation. There is no damage due to contact, and there is no contact resistance between the lower surface of the winding material and the upper surface of the transport rail when contacting the fixed material guide when adjusting the transport line, reducing contact stress and generating dust. It is possible to suppress the defect of the winding element due to scratches in the winding material or the entrainment of dust, and to improve the quality of the winding element.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows the configuration of the winding device of the present invention. A winding portion comprising a winding shaft 3 driven by a motor 2 and a winding shaft 5 of a belt-like winding material 1 (hereinafter referred to as winding material 1) supplied in a reel shape driven by a motor 4. A plurality of small-diameter holes installed along the conveying direction on the lower surface side of the take-up material between the dancer roll unit 6 and the take-up unit between the dancer roll unit 6 and the take-up unit were formed between the take-out units. A conveyance line regulation section comprising a conveyance rail 7 and a fixed material guide 8 that regulates and guides the conveyance line provided along the upper surface of the conveyance rail 7 and both sides of the winding material. It is the winding device comprised by the material cutter 9 which cuts a winding material in the taken stage.

  FIG. 2 shows the configuration of the winding line conveying line regulating section. A plurality of small-diameter holes 10 having a constant pitch and a narrow pitch are formed on the contact surface of the transport rail 7 with the winding material 1. The back surface of the transport rail 7 has a groove processed wider than the processed area of the small-diameter hole 10, and a block 12 provided with a nipple 11 for supplying air to the groove leaks air from the mounting surface. It is installed so as not to be sealed. A fixed material guide 8 that regulates the travel line of the winding material 1 is attached to the upper surface of the transport rail 7 so as to be slightly wider than the width of the winding material 1.

  Subsequently, these operations will be described with reference to FIGS. 1 and 2. The winding material 1 to which the hanging shaft 5 is attached and unwound is wound on the winding shaft 3 driven by the motor 2 through the conveyance line setting portion to which tension is applied by the dancer roll portion 6 to prevent winding deviation. The material is cut by the material cutter 9 that cuts the winding material 1 at the stage where the predetermined length is wound, whereby the winding element 13 is obtained. At this time, air is supplied from the nipple 11 of the block 12 attached to the back surface of the transport rail 7 of the transport line setting section. The supplied air is compressed in the groove portion of the block 12 and then ejected from a plurality of small diameter holes 10 formed on the upper surface of the transport rail 7. The winding material 1 traveling on the upper surface of the transport rail 7 floats from the upper surface of the transport rail 7 by the jetted compressed air, and the direct contact with the upper surface of the transport rail 7 is eliminated. Thereby, the damage | wound by the contact with the conveyance rail 7 during winding-up operation of the winding material 1 can be eliminated.

  Further, by causing the winding material 1 to float, the contact resistance between the upper surface of the transport rail 7 and the winding material 1 is eliminated, and the winding material 1 of the winding material 1 is corrected by correction when the transport line is shifted due to wrinkles of the winding material 1 or the like. Stress at the time of contact between both side parts and the fixed material guide 8 is reduced, and generation of dust due to falling off of cutting burrs, etc. that occurs during material removal can be suppressed, winding deviation is prevented, and scratches and dust are trapped. It is possible to reduce the occurrence of defective characteristics of the winding element due to the above.
