  However, in such a wire supply stand device 1, when there is a loosened wire 2a on the upper side of the sequentially drawn wire 2a, as shown by a virtual line in FIG. The electric wire 2a may also be lifted. In such a case, the electric wire 2a may be entangled and caught by the electric wire guide 6 or the like, and the electric wire 2a may not be smoothly supplied to the downstream electric wire processing apparatus side. .

  And when such entanglement of the electric wire 2a occurs, it is necessary to stop the operation of the apparatus each time, and the operator needs to correct the entanglement. There was also a problem that stabilization of the system could not be achieved.

  Therefore, the problem to be solved by the present invention is to provide an electric wire supply stand device capable of improving the productivity by reducing the occurrence of tangling of electric wires.

  Technical means for solving the above problems include a stand base portion on which a bundle of electric wires wound in a ring shape is placed, a post portion erected at the center of the stand base portion, and an upper end of the post portion And a plurality of guide flanges in the circumferential direction that are supported by the stand base portion so that the lower end portion can spread radially outwardly, and each guide rod is made up of a wire bundle placed on the stand base portion.

It is good also as a structure where the said weight body is mounted | worn with the fitting shape in the front-end | tip part of the other end while being fixed to an outer fitting shape.

  Further, the flexible string-like body is made of a flexible tube, and is fixedly attached to the drive shaft in a state where one end base portion of the flexible tube is externally fitted to the mandrel portion, and the other end of the flexible tube. It is good also as a structure where the said weight body is mounted | worn by the insertion shape in the front-end | tip part.

  Further, the mandrel portion may have a structure protruding with an acute angle with respect to the rotation axis of the drive shaft.

  According to the electric wire supply stand device of the present invention, the electric wire dropping mechanism is provided outside the electric wire bundle placed on the stand base, and the electric wire dropping mechanism is driven by the motor and the motor. One end base is fixed via a mandrel provided in a projecting manner to the drive shaft, and a flexible string-like body having a weight attached to the tip of the other end is provided for rotation of the drive shaft. The wire pull-out mechanism is arranged so that the rotation trajectory of the flexible string-like body that is rotationally driven intersects the pull-out trajectory of the drawn-out electric wire. Even if the slackened electric wires located on the upper side are lifted together with the supply, the flexible cord-like body is rotated across the drawing trajectory of the drawn wires, so that the flexible cord-like shape is rotated.

  In addition, if the mandrel portion has a structure that protrudes at an acute angle with respect to the rotational axis of the drive shaft, the flexible string-like body after the beating action on the electric wire by the flexible string-like body Is returned to the direction of escaping from the drawing track of the electric wire due to the decrease in centrifugal force, and therefore the electric wire can be effectively prevented from being caught.

  Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, an electric wire supply stand device 11 is provided with a wire bundle 12 wound in a ring shape as described above. The stand base portion 13, the support column portion 14 standing at the center of the stand base portion 13, the upper end is fixed to the upper end portion of the support post portion 14, and the lower end portion is provided on the stand base portion 13. A plurality of (4 in the illustrated example) guide flanges 15 are provided that extend radially outward along the radial guide grooves and are supported in a biased manner.

  Further, in the present embodiment, an electric wire drop-off mechanism 17 is further provided at a portion located slightly outside and slightly above the stand base portion 13 and on the lower side of the column portion 14. It is structured.

  The stand base portion 13 has a structure with an appropriate bottomed cylindrical shape having an inner diameter that can accommodate the wire bundle 12, and a radial guide groove for guiding the guide flange portions 15 is appropriately provided at the bottom thereof. Numbers are formed.

  The support column 14 is erected with a central hole formed in the stand base 13 as a penetrating shape, and has a structure having an appropriate height. And the upper end of each guide collar part 15 is fixed to the disk-shaped attachment plate 14a provided at the upper end part of the column part 14, respectively, and the lower end part of each guide collar part 15 is formed on the bottom part of the stand base part 13. In addition, the guide grooves are arranged in an inserted manner.

  At this time, each guide flange 15 is formed of a wire-like member such as a piano wire having elasticity, and the lower end portion is formed in a shape spreading radially outward. It is set as the structure supported in the state slightly urged | biased to the direction.

  The electric wire dropping mechanism 17 includes a motor 18, and a drive shaft 19 that is driven to rotate about a horizontal axis by the motor 18 has an axis perpendicular to the rotation axis of the drive shaft 19, and protrudes on both sides. A support shaft portion 20 as a mandrel portion having an appropriate length is provided to protrude.

  Each support shaft 20 is provided with an end base portion of a flexible tube 21 (for example, a screen door molding having irregularities on the surface) of an appropriate length made of a rubber material as a flexible string-like body. It is mounted in a fitting shape and is fixed by a fastening band or the like as appropriate. In addition, a piano wire 22 having an appropriate length as a weight body is fitted in the distal end portion of the other end, which is the free end side of each flexible tube 21, and an adhesive is attached to the inner surface of the flexible tube 21. The structure is fixed by, for example.

  And it is set as the structure where the motor 18 was attached and fixed to the support stand provided suitably. At this time, the rotation trajectory of the flexible tube 21 that is rotationally driven in accordance with the rotation of the drive shaft 19 in a predetermined direction passes through the gap between the guide flanges 15, and the electric wire placed on the stand base 13. An electric wire dropping mechanism 17 is arranged so as to intersect the drawing locus of the electric wires 12a drawn out from the bundle 12 sequentially.

  Further, in the present embodiment, a pair of wire drop mechanisms 17 are arranged separately from each other in the radial direction of the wire bundle 12, that is, the stand base portion 13, and each wire drop mechanism 17 is pulled out from the wire bundle 12. The rotation trajectory of the flexible tube 21 that intersects the lead trajectory of the electric wire 12a is driven to rotate so as to intersect from the upper side toward the lower side.

  The present embodiment is configured as described above. For example, the wire supply stand device 11 is arranged on the upstream side in the wire supply direction in a wire processing device such as an automatic cutting machine. And with operation of an electric wire processing apparatus, the electric wire 12a of the electric wire bundle 12 mounted in the stand base part 13 is pulled out upwards under guidance by each guide collar part 15, and is supplied sequentially via an electric wire guide. The electric wire 12a that has been subjected to a predetermined processing, for example, a harness having terminals crimped at both ends are sequentially manufactured.

  Along with the operation of the electric wire processing apparatus, the motors 18 of the electric wire removal mechanisms 17 are driven almost simultaneously, and the flexible tubes 21 are driven to rotate as the drive shaft 19 rotates. And since it arrange | positions so that the rotation locus | trajectory of the flexible tube 21 may cross | intersect with respect to the drawing locus | trajectory of the electric wire 12a pulled out upwards sequentially, it rotates from the upper side with respect to the electric wire 12a pulled out upwards. The driven flexible tube 21 strikes, and here, a tapping action on the electric wire 12a is exhibited.

  Therefore, even when the slackened electric wire 12a is caught and lifted together with the electric wire 12a drawn upward, the electric wire 12a lifted by the beating action by the flexible tube 21 is effectively discharged. It can be dropped, and the occurrence of tangling of the electric wire 12a due to inadvertent lifting of the loosened electric wire 12a can be effectively prevented.

  At this time, the piano wire 22 is attached to the distal end portion of each flexible tube 21, and the intermediate portion is soft and the distal end portion is hard and appropriately heavy. It can be brought close to the feeling that the lifted electric wire 12a is wiped off by a so-called human hand, and the effect of wiping off the electric wire 12a can be exhibited more efficiently.

  Further, the piano wire 22 is mounted in the distal end portion of the flexible tube 21 made of a rubber material or the like. Since the surface of the flexible tube 21 hits the electric wire 12a, the electric wire 12a is effectively damaged. Can be prevented. At this time, if the flexible tube 21 having a structure with irregularities on the surface, such as a screen door molding, is employed, the effect of removing the electric wire 12a by the contact resistance can be more efficiently exhibited.

  From the above, it is possible to effectively reduce the occurrence of entanglement of the drawn wire 12a, and more stable supply of the wire 12a is possible, and the productivity of the wire processing apparatus can be improved.

  Moreover, since the flexible tube 21 is used as the flexible string-like body, it can be mounted by being externally fitted to the support shaft portion 20, and when the piano wire 22 is mounted, There is an advantage that it can be easily mounted.

  Further, since the wire dropping mechanism 17 is provided separately from each other in the radial direction of the wire bundle 12, the tapping action by the flexible tube 21 can be exhibited at a plurality of locations separated in the radial direction, and the electric wire 12a is dropped off. The action can be exhibited more efficiently, and the occurrence of tangling of the electric wire 12a can be further reduced.

  Moreover, since each electric wire dropping mechanism 17 is provided above the electric wire bundle 12 and on the lower side of the support column 14, the effect of removing the electric wire 12a at the initial stage of lifting the loosened electric wire 12a is exhibited. It is possible to wipe off the electric wire 12a more efficiently.

  3 to 6 show a second embodiment, and the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  That is, according to the present embodiment, the drive shaft 19 is detachably attached to the rotating shaft 18 a of the motor 18, and the flexible tube 21 is detachably attached to the drive shaft 19. The drive shaft 19 is provided with an insertion hole 19a into which the rotary shaft 18a is inserted at one end surface in the axial direction thereof. The drive shaft 19 is retained and retained by inserting the rotary shaft 18a into the insertion hole 19a and tightening the fixing screw 25. The structure rotates integrally.

  Further, the other end of the drive shaft 19 is gradually tapered, and mounting surfaces 19b intersecting the axial direction are formed on both sides thereof, and the flexible tube 21 is mounted on each mounting surface 19b. A tube mounting hole 19c is formed. At this time, as shown in FIG. 4, each tube mounting hole 19 c has an acute angle θ with respect to the rotational axis P of the drive shaft 19, for example, θ = 45 degrees in the present embodiment. Is formed.

  Then, a piano wire 26 having an appropriate length as a mandrel is fitted into the base of one end of the flexible tube 21, and in this state, the piano wire 26 is inserted into the tube mounting hole 19c of the drive shaft 19 and fixed. By tightening 27, it is structured to be retained. Each piano wire 26 has a length protruding from the tube mounting hole 19c, and as shown in FIG. 6, the flexible tubes 21 on both sides are detachable in a state of being displaced in the height direction. It is supposed to be attached to the structure.

  Similarly, a piano wire 28 having an appropriate length as a weight body is also fitted in the distal end of the other end, which is the free end side of each flexible tube 21, so that the inner surface of the flexible tube 21 is fitted. It is made into the structure fixed to the surface with the adhesive agent etc.

  In this embodiment, as shown in FIGS. 3 and 4, when the motor 18 is stopped, each flexible tube 21 has an appropriate acute angle θ with respect to the rotation axis P due to its elasticity. As shown in phantom lines, the flexible tube 21 is spread and rotated by centrifugal force due to the rotation of the drive shaft 19 accompanying the rotation of the rotation shaft 18a by the drive of the motor 18. It is said that.

  Then, as shown in FIG. 3, the rotation trajectory of the flexible tube 21 that is driven to rotate passes through the gap between the guide flanges 15, and from the wire bundle 12 placed on the stand base 13. An electric wire dropping mechanism 17 is arranged so as to intersect with the drawing locus of the electric wires 12a drawn out sequentially.

  At this time, when the motor 18 is stopped from the driving state, the electric wires 12a are sequentially pulled out in the direction in which the flexible tube 21 is returned to the natural state from the expanded state by the centrifugal force. A wire bundle 12 in a predetermined winding direction is placed on the stand base 13. For example, in the present embodiment, the winding direction of the placed wire bundle 12 is a left-handed structure.

  Also in the present embodiment, a pair of wire drop-off mechanisms 17 are arranged in the radial direction of the wire bundle 12 at a portion located on the lower side of the support column 14, and each wire drop-off mechanism 17. Is configured to be rotationally driven so that the rotation trajectory of the flexible tube 21 intersecting the extraction trajectory of the electric wire 12a drawn from the electric wire bundle 12 intersects from the upper side toward the lower side.

  Therefore, in the present embodiment, as in the first embodiment, even when the slackened electric wires 12a are caught and lifted together with the electric wires 12a that are sequentially drawn upward, the electric wires 12a are lifted by the hitting action. The wire 12a can be efficiently wiped off, and the advantages such as the effective prevention of the entanglement of the wire 12a can be exhibited, the supply of the wire 12a can be more stable, and the productivity of the wire processing apparatus can be improved. I can plan.

  In particular, each flexible tube 21 has a protruding structure with an acute angle θ with respect to the rotational axis P of the drive shaft 19 in its natural state. After the beating action, the flexible tube 21 is instantaneously returned from the large-diameter rotation locus that spreads outward due to the decrease in centrifugal force to the direction approaching the rotation axis P, which is the natural state. Since the rotation trajectory has a small diameter and returns to the direction of escaping from the drawn trajectory of the drawn electric wire 12a, it is possible to effectively prevent the electric wire 12a from being caught after the beating action on the electric wire 12a.

  After that, the flexible tube 21 is returned to the original rotation trajectory, and the same hitting action can be exhibited. Regardless of the drawing speed of the electric wire 12a such as high speed and low speed, the electric wire 12a lifted along with the drawn electric wire 12a can be efficiently removed without any trouble.

  The rotational speed of each flexible tube 21 may be set as appropriate. For example, when the pull-out supply speed of the electric wire 12a is fast, the rotational speed of the drive shaft 19 driven by the motor 18 is set to be high. However, when the pull-out supply speed of the electric wire 12a is low, the rotation speed of the drive shaft 19 driven by the motor 18 may be set to be low.

  Moreover, although the structure using the flexible tube 21 is shown as a flexible string-like body, a solid rubber string etc. may be sufficient and it is not limited to embodiment at all.

  Furthermore, the drive shaft 19 is not limited to a structure that is detachably attached to the rotation shaft 18a of the motor 18 as in the present embodiment, and the rotation shaft 18a may be the drive shaft 19, and the drive shaft 19 may be appropriately connected via a transmission mechanism. The structure may be rotationally driven, and is not limited to the embodiment.

  Further, the drive shaft 19 is provided with a tube mounting hole 19c, and the base end of the flexible tube 21 into which the piano wire 26 is inserted is inserted and fixed in the tube mounting hole 19c, whereby the rotational axis of the drive shaft 19 is fixed. Although it has a structure that protrudes with an acute angle θ with respect to P, the support shaft portion 20 protruding from the drive shaft 19 as in the first embodiment is arranged in a bent shape, Similarly, it may have a structure that protrudes with an acute angle θ with respect to the rotation axis P of the drive shaft 19.
