Description

  The present invention relates to a wire rod guide device for guiding a wire rod from a wire bundle around which the wire rod is wound to a wire rod conveying device for feeding the wire rod.

  As a wire guide device for guiding a wire from a wire bundle around which the wire is wound to a wire conveying device for sending the wire, a base member on which the wire bundle is placed and a base member are provided above and below. Proposed with a conical cylindrical shape that has a conical cylindrical shape that allows a wire rod from a wire bundle to be inserted from below, and a guide pulley that is provided above the collector and on which the wire rod that passes through the collector is hung (Patent Document 1).

  In the technique of Patent Document 1, when a wire is drawn from a wire bundle placed on a base member of the wire guide device by feeding the wire with a wire conveying device, the wire is wound in an annular shape in the wire bundle. Therefore, since the drawn wire rod swings in a spiral shape, the collector between the base member and the guide pulley converges the swing of the wire rod so that it does not come off the guide pulley.

  However, in the technique of Patent Document 1, the wire drawn from the wire bundle placed on the base member is swirled in a spiral manner until reaching the collector. And kink like knots. When the kink is generated in the wire, there is a problem that the kink portion becomes a defect and a defective product is manufactured in a downstream process, or the wire cannot be fed due to the kink portion.

JP 2007-115423 A

  Then, this invention makes it a subject to provide the wire guide apparatus which can suppress generation | occurrence | production of a kink when pulling out a wire from a wire bundle in view of said situation.

  In order to solve the above-described problems, the wire guide device according to the present invention includes: a base member on which a wire bundle around which a wire is wound without a core is placed, and an upper side from the end of the base member. A side member protruding to the side member, a vertical rail member attached to the side member, a slider guided by the rail member, and a mounting member that moves up and down above the base member, A wire rod insertion hole penetrating the mounting member in the vertical direction, and a holding mechanism that is attached to the upper end side of the side member and holds the mounting member at the upper end of the vertical movement. '' Features.

  Here, examples of “wires” include “electric wires (covered wires, bare wires)”, “wire cables”, “welding wires”, “copper wires”, “aluminum wires”, and “steel wires”. it can.

  The “holding mechanism” includes a “mechanism that holds a magnet on one side of a side member or a mounting member and magnetizes the iron plate provided on the other side”, “a side member or a mounting member”. "Mechanism for holding by holding a locking claw on one side of the member and hooking the locking claw on a locked portion provided on the other side", "Placing member on both side member and mounting member Can be exemplified by a mechanism in which a hole that coincides in the horizontal direction is provided when the is positioned at the upper end of the vertical movement and is held by inserting a pin into the coincident hole.

  In the wire guide device of this configuration, the mounting member is moved to the upper end of the vertical movement and held by the holding mechanism so as not to move downward. Wire, reelless winding, etc.) are placed on the base member such that the center thereof is located below the wire insertion hole penetrating the placement member. Then, the wire drawn from the inner peripheral side of the wire bundle is inserted from below into the wire insertion hole penetrating the mounting member, and set to the wire conveyance device provided on the next process side. Thereafter, holding of the mounting member by the holding mechanism is released, the mounting member is moved downward via the slider guided by the rail member, and is mounted on the wire bundle.

  In this state, when the wire rod is sent by the wire rod conveying device and pulled, the wire rod wound around the wire rod bundle is pulled out through the wire rod insertion hole penetrating the mounting member. At this time, since the placing member is placed on the wire bundle, the wire insertion hole is closer to the wire bundle than the distance between the wire bundle and the collector in the technique of Patent Document 1, Before the wire drawn out from the bundle becomes spiral, it passes through the wire insertion hole, and the wire becomes linear from the inner periphery of the wire bundle to the wire insertion hole. And a wire is pulled out straight by passing through a wire insertion hole.

  Thus, according to the wire guide device of this configuration, since the wire drawn from the inner peripheral side of the wire bundle is linear until it reaches the wire insertion hole, the wire is bent or spiraled. It is possible to avoid the occurrence of kinks such as kinks and knots on the wire.

  In addition, the mounting member can be moved above the bundle of wire rods by the rail member via the slider, and the mounting member can be held by the holding mechanism at the upper end of the vertical movement. When placing or exchanging the bundle, the placing member does not get in the way, and the work such as placing and exchanging the wire bundle can be easily performed.

  In addition, since the mounting member is moved up and down by the rail member, the movement of the mounting member in the direction (horizontal direction) perpendicular to the vertical direction can be regulated by the rail member. By pulling out the wire through the hole, the mounting member does not move in the horizontal direction even if force is applied to the mounting member in the horizontal direction via the wire insertion hole. Therefore, the shaft core of the wire insertion hole is not shaken, and the wire can be drawn upward in a stable state.

  In addition to the above-described configuration, the wire rod guide device according to the present invention may include: “The mounting member further includes a guide portion that protrudes downward in a conical shape in which a lower end side is narrowed, and the wire rod insertion hole May be vertically penetrated at the lower end of the guide portion ”.

  By the way, in the wire rod guide device, when the wire rod is pulled out intermittently, when the wire rod drawing is stopped, the wire rod is neatly wound around the inner circumference of the wire rod bundle by the inertial force acting on the wire rod by being pulled out. The wire may be unwound in an annular shape over several turns. Then, when the drawing of the wire rod is resumed in such a state, the wire rod is drawn out so that the diameter of the ring that has been unrolled becomes small, so depending on the degree of overlap of the unrolled wire rod, There is a risk of kinking.

  According to the wire guide device of this configuration, since the mounting member has the conical (inverted conical) guide portion protruding downward, when the mounting member is mounted on the wire bundle, the inverted cone The guide portion is in a state of being inserted from above into the inside of the wire bundle (center side relative to the inner periphery). In this state, when the wire is pulled out through the wire insertion hole penetrating at the lower end of the guide portion, if the wire is unrolled inside the wire bundle for some reason, the diameter of the ring unrolled becomes small. As a result, the wire is pulled out, but if the diameter of the ring becomes small to some extent, it will come into contact with the surface of the guide part, and it can be prevented that the diameter of the ring becomes small enough to make a knot, and the occurrence of kink Can be prevented.

  Moreover, even if intermittent pulling out of the wire bundle that makes it easy to unwind the wire rod is performed, as described above, the occurrence of kinks can be prevented by the inverted conical guide portion. Accordingly, the wire guide device of this configuration is used as a wire guide device for supplying a wire to a device (for example, a terminal crimping device that crimps a terminal to the end of the wire) that needs to be intermittently pulled out and supplied. It can be used suitably.

  Furthermore, in addition to the above-described configuration, the wire guide device according to the present invention is “attached to the mounting member so that it protrudes in a cylindrical shape upward from the mounting member and is continuous with the wire insertion hole”. It is also possible to further include a guide tube that is provided.

  According to the wire guide device of this configuration, since the wire from the wire bundle is drawn to the outside through the wire insertion hole and the guide tube, the wire can be prevented from being greatly loosened by the guide tube. It is possible to reduce the occurrence of kinks due to the slack of the knot.

  As described above, as an effect of the present invention, it is possible to provide a wire guide device that can suppress the generation of kinks when a wire is drawn from a wire bundle.

Therefore, when placing or exchanging the wire bundle 3 with respect to the base member 11, the placing member 15 does not get in the way, and the work such as placing and exchanging the wire bundle 3 is easy. can do.

  Further, since the mounting member 15 is moved up and down by the rail member 14, movement of the mounting member 15 in the direction (horizontal direction) perpendicular to the vertical direction can be restricted by the rail member 14. Therefore, when the wire 2 is pulled out through the wire insertion hole 16, the placement member 15 does not move in the horizontal direction even if a force is applied to the placement member 15 through the wire insertion hole 16 in the horizontal direction. . Therefore, the axis of the wire insertion hole 16 is not shaken, and the wire 2 can be pulled out in a stable state.

  Furthermore, since the main body portion 15c of the mounting member 15 is transparent, even when the mounting member 15 is mounted on the wire bundle 3, the upper surface of the wire bundle 3 can be seen through the main body portion 15c. The remaining amount of the wire 2 can be confirmed.
