Definitions
- the present invention relates to a method of manufacturing a roll of a thermoplastic resin string, and more particularly, to a method of manufacturing a roll of a thermoplastic resin string without a core.
- a method for manufacturing a wound body of a thermoplastic resin string having no core there is a method disclosed in Japanese Patent Application Laid-Open No. 2000-134424.
- a through-hole is provided in the superposed resin string inside the coil, and the resin string is connected by fusing the periphery of the writing through-hole.
- a method of piercing and fusing in the diameter direction from the center of the coil using a heating needle during the winding process, and a method of ultrasonic welding are used. It has been disclosed.
- the heating needle 109 is penetrated from the inside of the string 110.
- the molten resin 103 that has melted enters the gap 105 around the through hole 101. Further, the non-penetrating portion 107 is easily formed. In this method, it is necessary to properly control many variables such as production atmosphere temperature, insertion time, and heater temperature in order to obtain an appropriate bonding strength (peel strength).
- the ultrasonic welding method uses a horn 1 1 4 with a string 1 1 4 sandwiched between the horn 1 1 4 and the anvil 1 1 6 Ultrasonic vibration is applied to 10 and the frictional heat generated by this vibration forms the fused joint 1 1 2.
- the horn 114 used in this method if the horn 114 has a large area in contact with the cord 110, the joining strength is too large and the cord does not peel off when the cord is pulled out from the reel. I can not use it. On the other hand, when this area is reduced, the peel strength decreases, and the string can be easily peeled at the time of drawing out the string.
- the resin 103 pressed by the horn 124 or the horn 134 forces the volume of the horn inserted. , String 1 1 0-Enter between 110.
- the infiltrated resin 103 is a factor that causes the peel strength to be excessive. Therefore, a configuration without an anvil is desired.
- a configuration without an anvil for example, a configuration in which the horn 134 is inserted from the inside as shown in FIG. 11 is possible if the horn and the oscillator can be miniaturized.
- the horn and the oscillator since it is necessary to adjust the insertion depth of the horns 134, it is rather preferable to insert the horn from the outside.
- the number of the strings is three or more, it is necessary to consider that an interface 61 is easily formed between the molten portion and the string forming the drawn fiber layer.
- the tip of the horn has a round shape as shown in FIG. 12, the resin pressed by the horn 115 easily enters between the cords 110-110. From this viewpoint, it is desirable that the tip of the horn be flat.
- thermoplastic resin string used for packing if the packing material is heavy, a polyester string is used for this. It is, of course, important that the polyester string can withstand the weight of such packages.
- thermoplastic resin string for example, a polypropylene string, a polyester string, or the like is used, and a configuration in which the characteristics and use of each material is considered is desired.
- a polypropylene string, a polyester string, or the like is used, and a configuration in which the characteristics and use of each material is considered is desired.
- the characteristics of this material and the problems when using it as a packing string are described below.
- Table 1 below shows the properties of each of the polypropylene and polyester cords.
- the diameter d of the through-hole of each string is 1 mm, and the width w of the string is 15.5 mm.
- FIG. 13 is a diagram for explaining the characteristics of the polypropylene thermoplastic resin strings shown in Table 1
- FIG. 14 is a diagram for explaining the characteristics of the polyester thermoplastic resin strings shown in Table 1.
- the polypropylene thermoplastic resin string As shown in Table 1, 1 mm (hole diameter a) Z l 5.5 While the strength of mm (band width b) is reduced, the strength of the polyester string is reduced by (1 mm or more / 5.5 mm), and the strength is reduced to the hole diameter or more.
- the polypropylene thermoplastic resin string does not tear in the width direction because the fiberization proceeds in the longitudinal direction (L direction in FIG. 13) by stretching.
- notch strength in the width direction is low because remarkable fiberization does not progress in the long direction even when stretched. As a result, as shown in FIG. 14, it is easy to tear in the width direction. Therefore, in a roll using a method of completely penetrating the polyester thermoplastic resin string, the string may be broken when the heavy package is tightened by a packing machine or when the heavy package is transported.
- the thermoplastic resin cord of the thermoplastic resin cord does not have the inner surface of the coreless roll of the thermoplastic resin string collapsed and does not cause stringing or longitudinal tearing of the string during use. It is a first object to provide a method for manufacturing a coiled body. Furthermore, when a polyester string is used as the thermoplastic resin string, a coreless wound body that has a small decrease in tensile strength and can obtain an appropriate peel strength is realized. It is a second object of the present invention to provide a method of manufacturing a coreless wound body that can be smoothly pulled out of a roll. Disclosure of the invention
- a method for manufacturing a wound body of a thermoplastic resin string comprises a plurality of core pieces arranged along a circumference, each of which is capable of moving back and forth in a diametrical direction.
- the end of the thermoplastic resin string is used in a state where each core piece of the core is expanded in the diameter direction.
- thermoplastic resin string is continuously wound to produce a rolled body. Insert the horn into the thermoplastic resin string and excavate while melting By, characterized by linking the thermoplastic resin cord of the plurality of layers.
- a core piece having a groove formed on the outer surface side of each of the core pieces is used, and a plurality of through-holes penetrating the thermoplastic resin string covering the groove are formed by inserting the horn. It may be configured to be formed by excavating while melting the thermoplastic resin string of the layer.
- the contact portion of the horn may be an outer peripheral surface of the plurality of layers of the thermoplastic resin string, and the excavation may be performed while melting from an outer peripheral side to an inner surface side of the thermoplastic resin resin string.
- the horn in the method of forming a through-hole, it is preferable that the horn has a cylindrical shape and a diameter of 1 mm or less. This is because the peel strength of the string increases as the circumference of the horn increases, so that the string easily tears when the diameter exceeds 1 mm.
