Abstract

The present invention relates to a wire manufacturing apparatus having a conical cylinder inverted in a spool, wherein the upper end diameter of the cylinder is larger than the diameter of the bottom end, while the tape is wound over the wire by the centrifugal force of the rotation in the winding process. This allows the tape to be wound over the unwound wire from the spool going from the low point to the high point of the cylinder. This prevents subsequent rotation of the tape from loosening out of the spool and has the advantage of allowing the tape to be firmly wound over the wire in continuous, even and high speed operation.

Description

Wire Manufacturing Equipment {APPARATUS FOR MANUFACTURING WIRE}

TECHNICAL FIELD The present invention relates to the manufacture of wires, and in particular to devices for manufacturing wires, cables, cords and handicrafts or decorative articles.

Conventional wire fabrication methods employ an extrusion manufacturing process that uniformly extrudes opaque plastic material onto a plurality of wire surfaces, each wire being surrounded by an insulating material, and having a uniform outer protective layer with good insulation. Will form. According to the method of making colored wires, producing the desired color is simply adding dye to the plastic raw material during the process. Obtaining color by using traditional techniques is monotonous or irregular and could not give the wires a variety of appearances.

According to conventional wires used to make handicrafts and other decorative articles, they are generally distributed in soft wires, giving strength to rigid wires. Typically, soft wires are formed by twisting colored filaments by using traditional manufacturing processes and are monotonous and labor consuming. This kind of soft wire was easily dirty, difficult to clean, and faded in color. Moreover, the soft wire was limited in the application because no reinforcing member such as a rigid metal or nonmetal material was inserted into the wire. Therefore, wire manufacturers in the art meet the above method of producing wires with metal and non-metallic supports inside using an extrusion process that uniformly extrudes opaque plastics onto the surface of the metal or non-metal reinforcement member. Was made. As a result, the wire can also be colored by adding dye to the plastic material in the extrusion process. However, the wire could provide monotonous and irregular colors and could not be shiny or varied in color.

Currently, the method of winding the thread is used to manufacture the electric wire. The method involves wrapping cotton strands or the like onto the strands of the wire so that they are evenly tied together, and uniformly extruded the opaque plastic raw material over the wound wire to provide a uniform outer surface with good insulation. A protective layer is formed. This method is implemented as shown in FIG. The apparatus, together with the rotary seat 13, the belt 16, and the rotary seat 13 above the machine frame 80, forms the continuous drive of the drive unit 81 and the belt 16. Moreover, the vertical hollow shaft 14 is fixedly coupled to the center of the rotary sheet 13. The hollow shaft 14 simultaneously rotates while the rotating seat 13 is rotated by the drive of the belt 16 according to the drive of the drive device 81. In addition, the apparatus includes a spool having a hollow cylinder 153 with a rotation axis and a rim 152 at its respective end, wherein the seals 10 formed of a pure surface or the like have a cylinder 153 between the rims 152. Wound on)

According to FIG. 1, during the winding of the seal 10 over the wire 12, the process is carried out with the hollow cylinder 153 of the spool 15 above the hollow shaft 14 with the rim 152 over the rotating seat 13. ), Wound on the wire 12 through the hollow shaft 14 from the bottom of the rotating sheet 13 and the rotating sheet 13, and above the one or more hollow shafts 14 of the winding device 82. Pull the wire 12 from it, wind one end of the seal 10 around the wire 12 above the hollow shaft 14, and drive to rotate the spool 15 and maintain the wire 12 pulled Rotating the device. At this moment, the seal 10 is not wound from the spool 15 due to the centrifugal force of rotation, and is sequentially wound to the wire 12.

In view of the above, since the yarn 10 is made of twisted cotton or other fibers, the adjoining of the yarn 10 wound on the spool 15 by a frictional force in which a predetermined tensile force and friction force interact between the fibers. Exists between rotations. When the spool rotates, the seal 10 is released from the spool 15 by the centrifugal force of rotation, and is sequentially wound onto the wire 12. At the same time, the mutual frictional force between the fibers of adjacent windings of the yarn 10 allows for the sequential rotation of the yarn and still winds up onto the spool without baggage from the spool. Therefore, the outer diameter from the top to the bottom of the hollow cylinder is the same to wind the yarn evenly over the cylinder 151 of the spool 15.

However, during the winding of fine yarns with a light weight over the wire by using the above winding method, the yarn may become loose because there is not enough tensile force caused by the air friction, so that the yarn is tight over the wire. You won't be able to wind it up. Thereafter, the rotation of the yarn wound thereon may be separated from the wire by a sequential extrusion process by the compression force of the extrusion. The unwinding of the thread will easily catch on each other and will degrade the quality of forming a cable with a uniform outer layer. The solution of the above problem proposes to mount the flywheel 27 on the hollow shaft 24 above the spool 25 shown in FIG. 2, the flywheel 27 being formed of a bent metal rod and having a center hole 273. ), Two arms 272 extending outwards in opposite directions, and two eyes 271 formed at the open ends of the arms 272, respectively. While the smooth thread 20 is wound over the wire 20, the process involves threading the thread 20 through the eye 271 before winding the thread over the wire 22, the spool 25 and the flywheel. 27) further comprising driving a drive and a winding device (both not shown) to rotate. The rotational speed of the flywheel 27 will be slightly higher than the rotational speed of the spool 25 after a short period of operation time due to the inertia of the flywheel 27. At this moment, the flywheel 27 will be subjected to a predetermined force (eg, tensile force) over the thread 20 released from the spool 25 by the centrifugal force of rotation. As a result, the loosened yarn 20 is wound tightly upwards of the wire 22 in sequence.

When using a heavier thread of heavy weight, a relatively large tensile force is required to be exerted above the thread while winding the thread over the spool. Likewise, the thread is wound tightly over the spool, with the result that the mutual friction between adjacent windings of the thread is reduced. This may cause the yarn to be difficult to unwind from the spools that are wound sequentially over the wire in the manufacturing process. In a harsh environment, the thread may break due to large tension during winding and eventually slow the winding process. In Fig. 3 in which the solution of the above problem is described, the spool 35 is formed to have a conical cylinder 351. The line from the top of the bottom circumferential surface of the cylinder 351 has an angle α with respect to the vertical line, and the diameter of the upper end of the cylinder 351 is smaller than the diameter of the lower end. Carefully, the unwinding thread will go from the low position of the cylinder with the large diameter indicated by reference 302 to the high position of the cylinder with the small diameter indicated by reference numeral 301 prior to the winding of the wire. These branches will moderate the tension. Therefore, the thread loosened from the spool 35 is not caught with the adjacent windings. As a result, the thread is wound more easily and smoothly above the wire.

Since the yarn is made by twisting cotton or other fibers, the tension and friction forces between the windings of the yarn wound on the spool by mutual frictional forces between the fibers are loosened out of the spool during the winding over the wire. This will prevent the sequential rotation of the thread on the spool. However, it is shown in FIG. 4 that the flat, light, soft, and resilient tape 45, like Mylar coated metal tape with metal film, is wound on top of the spool 45. It is clear that the following problems arising due to the mutual frictional force between the rotation of the tape 400 wound on the spool are distinct from those of the typical thread.

(1) A predetermined tensile force must be applied to the tape while the tape 400 is wound on the spool 45, which will cause the tape 400 to be firmly wound on the spool 45. However, in using any one of the above prior art to wrap tape 400 above wire 42, the tensile force is tape 400 released from spool 45 prior to wrapping above wire 42. It may be released by the winding of and may indicate the continuous rotation of the tapes 401, 402, 403. Likewise, the rotations 401, 402, 403 are about to be separated from the spool 45 by the small friction forces present therebetween, and are caught by each other. Engaged rotation (402, 403. See FIG. 4) will break when a pulling force is applied to it. This will obviously reduce the manufacturing capacity in high quality wires, especially in high volume manufacturing.

(2) Typically, in order to allow the flywheel 47 to rotate freely, the clearance F is defined by the hollow shaft 46 (after which the flywheel 47 lies above) and the hollow shaft 46 above the flywheel 47. It is provided between the nuts 43 to be firm to the end unit of, the fixed distance (H) from the top of the nut 43 to the top of the rim 451 of the spool is maintained. This distance H increases the angle β of the tape 400 at the portion from the wire to the eye 471 of the flywheel 47 with respect to the top surface of the flywheel 47. Thus, the tape 400 wound over the wire 42 is not easily flattened and causes a sequential winding of the tape 400 that wraps over the pleats 48 of the wire 42, which is undesirable as shown in FIG. 5. Will not manufacture cables.

(3) However, if the angle β of the tape 400 at the portion from the wire 42 to the eye 471 of the flywheel 47 is too small with respect to the flywheel (eg wrapping angle), The bottom edge of the tape 400 rubs the nut 43, and the manufacturing process is stopped because the tape 400 can be easily broken in a high speed operation.

(4) Finally, in unfavorable conditions, the tape 400 at the part of the eye 471 of the flywheel 47 from the removal of the spool 45 rubs the edge of the rim 451 so that it is easily broken in high speed operation. do.

In this regard, it is inappropriate to use a conventional method of wrapping a flat, light, soft, resilient tape 400 over the wire to obtain the fastest method of wrapping the surface smoothly and evenly over the wire. That's a new kind of variety, and colored tape materials and metal-coated tapes still don't apply to wire manufacturing. Therefore, there is an improvement to overcome the drawbacks of the prior art above.

It is an object of the present invention to provide a wire making apparatus wherein at least one resilient tape is obliquely, evenly and firmly partially overlapped over at least one wire adjacent to the winding of the two tapes.

In the practice of the present invention, the spool of the device is configured to have an inverted conical cylinder whose diameter at the upper end is larger than the diameter at the lower end to form an angle between the outer circumferential surface of the upper bottom of the cylinder and the vertical line. Therefore, it is possible to unwind the tape from the low position of the large diameter cylinder to the spool while the tape is wrapped over the wire by the centrifugal force of rotation during the wrapping process. This has the advantage of gradually releasing the tension forces present in the winding of the tape wound onto the spool, which prevents sequential winding of the tape from being loosed out of the spool by suddenly relaxed tension and prevents it from being pinched together. do. As a result, the tape is continuously, evenly and firmly wrapped over the wire supplied at high speed.

Another embodiment of the present invention further comprises a flywheel having a central hole fitted over the hollow shaft, two arms extending in different directions, the two split ends have side pieces, respectively arranged at the open ends of the side pieces Have four eyes. While the tape is wrapped over the wire, the process is to wrap one end of the tape through the upper and lower eyes at one end of the flywheel, and wrap one end of the tape on the wire above the hollow shaft, Driving the drive means and the winding means to rotate the spool, unwinding the tape from the spool by using a centrifugal force of rotation, and continuously wrapping the tape over the wire.

In another embodiment of the present invention, the angle of the tape at the portion relative to the wire from being bisected is of some value to prevent rubbing the nut after the bisected end.

Furthermore, in the practice of the present invention, the angle of the bisected end is to protect the tape from rubbing the rim of the spool after passing the spool.

The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.

6 and 7, the apparatus according to the present invention is a hollow rotating sheet 53, a belt 56, a driving device (not shown) and the rotating sheet 53 and the belt are coupled to each other to form a chain drive, etc. It includes a machine frame (not shown) fitted upwards. Moreover, the vertical hollow shaft 54 is firmly coupled to the central portion of the rotating sheet 53. The rotating sheet 53 rotates while the belt 56 driven by the driving device is driven, and the hollow shaft 54 rotates continuously. The apparatus further comprises a spool 55 having a hollow cylinder 553 with a rotation axis and a rim 552 at both ends. The tape is wound over a cylinder between the rims 552.

Note that the term "tape (50)" has been used and has a continuous length of flat, light, soft (e.g. small friction), elastic properties such as Mylard or metallic film covered color tape. It is generally defined or referred to as a material. Any of the suitable materials having the above characteristics may be applied without departing from the spirit and scope of the present invention while used by those skilled in the art.

Referring to FIG. 6, while the tape 50 is wound over one or more wires 52, the process allows the cylinder to rotate at the same time as the spool 55 above the rotating sheet 53 and the rotating sheet 53. Mounting on hollow shaft 54 with bottom rim 552 of spool 55 on nail 531 (shown in two), hollow from bottom of rotating seat 53 and rotating seat 53. The wire 52 is pulled from the hollow shaft 54 above the spool 55 to one or more cylinders of a twisting and winding device (not shown) through the shaft 54, above the hollow shaft 54. Wrap one end of the tape 50 on the wire, and drive the drive and the rewinder to rotate the spool 55 and pull the wire 52, thereby to the spool 55 by the use of a rotary centrifugal force. Starting with the tape 50. As a result, the released tape 50 is continuously wrapped over the wire. Note that the term "wire 52" used herein is merely a typical example. The wire 52 may be replaced with a non-metallic wire wrapped in some material, such as molded from a metal or used in a non-metallic or metal or wire, cable, power cord, or the like without departing from the scope and spirit of the present invention. .

In an embodiment of the present invention, the tape 50 wound on the spool 55 has a flat, light, soft and elastic property. Furthermore, while the tape 50 is wound on the spool 55, a predetermined tensile force can be applied above the tape 50, thereby loosening it from being loosed by a small pulling force between adjacent windings of the tape 50. This will prevent it from being rolled up. The action of the tension force makes it possible to firmly wind the tape over the spool 55. However, referring to FIG. 7, while using the method of the present invention to wrap the tape 50 over the wire 52, the tensile force present in the outermost winding of the tape D1 wound on the spool 55. Silver is released while the tape D1 is pulled out of the spool 55 to form a winding of the subsequent tapes D2, D3, and the like. As such, windings such as D2, D3, and the like, are to be separated from the spool 55 by a small friction force between them, and D2 and D3 are pinched by each other when the pulling force is applied. Therefore, it is possible to move the tape from the high point of the cylinder with the large diameter to the low point of the cylinder with the small diameter while the tape is released from the spool by the centrifugal force of rotation in the wrapping process. In order to solve this problem, the spool 55 is formed to have an inverted conical cylinder 551, the diameter of the upper end of the cylinder from the bottom circumferential surface of the cylinder 551 at an angle θs with respect to the vertical line. It is larger than the diameter of the lower end to form a line of the main surface. Therefore, the angle θ s is a large diameter from the lower point of the cylinder having a smaller diameter while the tape 50 is wrapped over the wire 52 by the centrifugal force of rotation during the process of wrapping the tape 50 released from the spool 55. It can be taken up to the high point of the cylinder with. This has the advantage of gradually releasing the tensile force present in the winding of the tape 50 wound on the spool 55, and the winding following the loose tape from the spool 55 by sudden release of tension and being pinched together. There is an advantage to avoid. As a result, the tape is continuously, evenly and firmly wrapped over the wire fed in the high speed operation. During the wrapping process, the angle at which the tape is wound about the wire is always kept at a fixed value. Therefore, the tape is continuously and evenly wound over the wire to be fed, and two adjacent turns wound over the wire partially overlap. When in the extrusion process, the transparent plastic raw material is uniformly extruded over the surface of the tape wound wire to form a uniform outer protective layer. While bending the wire, the bending deformation of the wire does not result from the adjacent winding of the wrapped tape that separates from the wire, but remains hidden over the wire. Therefore, high quality wires that are shiny in various colors can be manufactured in certain processes, especially in large scale production.

In addition, since there is not enough tensile force in the tape due to the floating phenomenon caused by air resistance, the flat and light tape 50 cannot be tightly wrapped on top of the wire 52, and the wire ( 52) may be baggy at the top. In another embodiment of the present invention, the flywheel 57 is placed on the hollow shaft 54 at the top of the spool 55 to prevent the tape 50 from loosening. The nut 58 is also screwed onto the hollow shaft 54 above the flywheel 57 by a distance F (e.g. a gap). During the wrapping process, the wire 52 passes through the hole in the nut 58. The flywheel 57 includes a central hole 573 sandwiched over the hollow shaft 54, two arms 572 extending outward in different directions, and divided into two side pieces having respective ends ( 574 has an angle &thetas; u with respect to arm 572 and a lower face piece 574 has an angle &thetas; d with respect to each arm 572, and four eyes 571 are each at the open end face of side piece 574. Is formed.

In yet another embodiment, while the tape 50 is wound over the wire 52, the process involves the top eye at the end of the flywheel 57 before the tape 50 is wound over the wire 52. Threading the tape 50 through the lower eye 571. Angles θu and θd will produce the highest angle θf of winding the tape 50 relative to the wire 52. The angle θf does not cause the bottom edge of the tape 50 to rub the nut 58. Moreover, the angles θu and θd do not cause the tape 50 leaving the spool 55 to rub the edges of the rim 552. The wrapping process further includes a final step of driving the drive unit and the winding unit to rotate the spool 55 and the flywheel 57. A predetermined force acts on the tape 50 left by the flywheel 57, which has been precisely calculated to evenly wrap the tape 50 over the wire 52. In addition, the length and oblique angles of the side pieces 574 are designed to wrap continuously and evenly over the wires 52 fed upwards, so that two adjacent tapes 50 at the maximum angles relative to the wires 52. ) Winding partially overlap. According to the above process, it is possible to produce reliable high quality wire by winding the tape in mass production.

In practical implementation of the above embodiment for producing wires, various metal wires or insulated wires (one or more) having diameter ranges from 2 mm to approximately 6 mm were used. Then, flat, light, soft, elastic tapes such as Mylar or metal tape coated with a metal film having a thickness of about 0.015 mm to about 0.035 mm and a width of about 1 mm to about 3 mm are used for winding the tape with a wire rope. Applies to the device. The rotational speeds of the driving and winding devices, the weight and length of the flywheel, and the lengths and angles θu and θd of the side pieces 574 are designed to have maximum values through trial and error experiments. Also, for example, the winding angle θf relative to the wire is maintained at an angle of approximately 8-20 degrees. Moreover, two adjacent turns of the tape are partially overlapped (approximately 20% to 50% of the tape width). During the wrapping process under the above conditions, the device of the invention successfully produces the wire, wraps it continuously with the tape, and produces approximately 30,000 meters of wire without any tape breakage. Moreover, the wire wrapped with the tape has a smooth surface without wrinkles. After the wrapping process, the wire wrapped with the tape is sent to the extruder. In the extruder, the transparent plastic raw material is uniformly extruded onto the surface of the wire to form a soft protective layer on the outside of the wire. After the extrusion process, the wires are characterized by a shiny color, and the adjacent windings of the tape are not disassembled even if the bending force is applied there. Most importantly, the electrical properties, such as the shielding properties of the electromagnetic radiation of colored wires, cables or power cords, are well maintained by a metal film applied over the tape, which is also the case after many tests and experiments It is proven.

While the invention is described by the specific specification, numerous modifications and variations can be made without departing from the scope and spirit of the invention by the claims enumerated by those skilled in the art.

Electrical properties, such as the shielding properties of electromagnetic radiation from colored wires, cables or power cords, are well maintained by a metal film applied over the tape, which is also proven after a number of tests and experiments.
