Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to an apparatus for manufacturing serpentine wire rods, and particularly relates to a serpentine wire manufacturing device, which is an intermediate product for manufacturing continuous binding metal fittings used in multi-hole notebooks, etc. The present invention relates to a meandering wire manufacturing device that can be suitably applied to wire rod manufacturing.

(Prior Art) Conventionally, a device for manufacturing a meandering wire by meandering and bending a single wire has two rows of winding pins arranged in a staggered manner to wind the wire, so that the wire can be continuously bent. The wire is wound around the winding pin in a meandering manner by reciprocating the feeding head that is designed to be fed out between the winding pin rows and moving the winding pin and this feeding head relative to each other in the direction of the winding pin row. There is something configured like this.

(Problem to be solved by the invention) However, in this configuration, since the feeding head is moved back and forth, there is a limit to increasing the moving speed, and it is impossible to increase the production efficiency beyond a certain level. It was possible.

An object of the present invention is to provide a meandering wire manufacturing apparatus that can solve the above-mentioned problems and further improve production efficiency.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides an endless rotating body in which a large number of winding pins are arranged in two rows at predetermined intervals and in a staggered manner. , a rotating member rotatable around an axis substantially perpendicular to the movement plane of the winding pins is provided, and at the outer periphery of the rotating member, the locus of movement of the vertices of the pins in one row of the winding pins is A protrusion that engages and holds the wire is protrudingly provided at a position that is almost in contact with the other row and draws a circular trajectory passing outside the movement locus of the other row, and this protrusion and each of the winding pins of the one row are sequentially aligned with each other. is provided with a driving device that drives the rotating body and the rotating member in synchronization, and an extruding member that pushes out the wire rod engaged and held by the protrusion and transfers it to the winding pin of one row. do.

(Function) Since the present invention has the above-described configuration, when the end of the wire rod is engaged with the winding pin of the other row and the rotating body and the rotating member are driven synchronously, the rotation of the rotating member is caused. When the wire engages with the protrusion, the protrusion moves along a circular trajectory, and when the protrusion matches one of the winding pins in one row, the wire wrapped around the protrusion is removed by the extrusion member. is transferred to the winding pin, and the wire becomes wound around the winding pin. In this state, the wire rod passes in front of the next winding pin in the other row arranged in a staggered manner, and as the rotating member rotates further, its protrusion passes through the outside of this winding pin and moves to the other row. By rotating the wire toward the other row, the wire is wound onto the next winding pin in the other row, and by further rotation of the rotating member, the wire is wound onto the next winding pin in one row in the same manner as above. When the protrusion matches the pin, the wire is transferred to the winding pin and wound, and by repeating the same operation, the wire is bent in a serpentine shape between the two rows of winding pins. . In this way, the wire can be bent into a serpentine shape by the rotation of the rotating body equipped with two rows of winding pins, the rotation of the rotating member equipped with a protrusion, and the extrusion of the wire by the extrusion member. Therefore, their operating speed can be increased compared to reciprocating operations, and production efficiency can be increased.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. In FIGS. 1 to 4, 1 is a cylindrical rotating body rotatably supported around its axis,
A large number of winding pins 2 and 3 are protruded in two rows at a predetermined interval corresponding to the meandering width on its outer peripheral surface. These winding pitches 2 and 3 are arranged at predetermined pitches and in a staggered manner, and the rotating body 1 is provided with a Geneva mechanism so as to rotate intermittently at every rotation angle corresponding to the pitch of the winding pins 2 and 3. It is rotationally driven by a drive device (not shown) equipped with the like. The winding pins 2 in one row are relatively low in height, and the winding pins in the other row are relatively high and protrude. A rotating member 4 rotatable about an axis substantially perpendicular to the axis of the rotating body 1 is arranged on the outer peripheral surface of the rotating body 1 at appropriate intervals. Projections 5 are provided at two locations in the diametrical direction on the outer periphery of the rotating member 4 on the side of the rotating body 1 so that their tips protrude close to the winding pin 2 . This rotary member 4 has a structure in which the locus of movement of the tips of the protrusions 5 as it rotates is approximately tangential to the locus of movement of the vertices of the hoisting pins 2 of the one row, and It is configured to have a circular trajectory passing outside the movement trajectory. Furthermore, the stop position of the winding pin 2 due to the intermittent rotation of the rotating body 1 is configured such that the locus of movement of the winding pin 2 and the movement locus of the protrusion 5 touch, and the rotating member 4 is also driven. A device (not shown) stops the protrusion 5 synchronously at the stop position of the winding pin 2, and rotates the winding pin 2 and the projection 5 intermittently by half a rotation so that they align on the same axis. is configured to do so. A push-out member 7 is disposed on the upper outer periphery of the protrusion 5 to push out the wire 6 engaged with the protrusion 5 and transfer it to the winding pin 2, and an operating device (not shown) is provided to operate the push-out member 7. is the rotating member 4 itself or the rotating member 4
It is placed on the side of the. The wire rod 6 is supplied from one side in the axial direction of the rotating body 1, and a braking mechanism 8 for applying tension to the wire rod 6 is disposed in the middle.

In the above configuration, in order to manufacture a serpentine wire rod, the wire rod 6 is supplied between the rotating body 1 and the rotating member 4, and its ends are engaged and fixed to the long winding pins 3 of the other rows, and The rotating body 1 is driven by a drive device (not shown).
and the rotating member 4 is synchronously driven to rotate intermittently. Then, as shown in FIGS. 3 and 4, as the rotating member 4 rotates, the wire rod 6 engages with the protrusion 5 of the rotating member 4.
In this state, when the protrusion 5 moves along a circular trajectory as shown by the imaginary line in FIG. 4, the wire 6 is wound around the winding pin 3 of the other row by 180 degrees and held in engagement. When the protrusion 5 matches the winding pin 2 in one row, the wire rod 6 is also wound around this protrusion 5 by 180 degrees, and the rotating body 1 and the rotating member 4
is temporarily stopped, and the extrusion member 7 transfers the wire rod 6 wound around the protrusion 5 to the winding pin 2, so that the wire rod 6 is wound around the winding pin 2. In this state, the wire rod 6 passes through the forward position in the moving direction of the next winding pin 3 in the other row arranged in a staggered manner. Then, as the rotating body 1 rotates again, the rotating member 4 rotates, and its protrusion 5 passes through the outside of the winding pin 3 and rotates toward one row of winding pins 2. The wire rod 6 engages with the next winding pin 3 in the other row, and as the rotating member 4 further rotates, the next winding pin 3 in one row
The protrusion 5 matches with the wire rod 6, and the wire rod 6 is transferred to the winding pin 2 and wound thereon, and the same operation is repeated thereafter, so that the wire rod 6 is formed in a meandering shape between the two rows of winding pins 2 and 3. It will be bent to

Note that the present invention is not limited to the above embodiments, and can be implemented in various ways. For example, in the above embodiment, the rotating body 1 and the rotating member 4 are configured to be driven intermittently, but it is not necessarily necessary to drive them intermittently, and even if the speed is reduced at the stop position, Furthermore, it is only necessary to synchronize the winding pin 2 and the protrusion 5 so that they match.

Further, in the above embodiment, in the process in which the wire rod 6 is wound around the winding pin 3 by the protrusion 5, relative movement occurs between the protrusion 5 and the wire rod 6, and the wire rod 6 is rubbed. , problems occur when vinyl-coated wires are used. In such a case, it is preferable to increase the radius of the circular locus of the protrusion 5 to minimize the relative movement.

Further, in the above embodiment, by making the winding pins 3 of the other row protrude long, the wire rod 6 engaged with the protrusion 5 is wound around the winding pins 3 as the rotating member 4 rotates. However, even if the winding pin 3 is not made long, the protrusion can be formed near the winding pin 3 by slightly inclining the axis of rotation of the rotating member 4 as shown in FIG. 5 can be brought close to the outer circumferential surface of the rotating body 1 so that the wire rod 6 can be reliably wound around the winding pin 3 as the protrusion 5 rotates. Furthermore, in the above embodiment, two protrusions 5 are provided on the rotating member 4 to improve efficiency, but one
You can have just one.

Moreover, instead of pushing out the wire 6 from the protrusion 5 and winding it around only one of the winding pins 2 as described above, the wire 6 is pushed out from the projection on both winding pins 2 and 3. You can also wrap it around the
In that case, it can be configured as shown in FIG. In FIG. 6, the rotating member 14 is configured such that its rotational axis is located on the locus of movement of the three winding pins in the other row, and a protrusion 15 is provided at the axis position, and a protrusion 15 is provided on the winding pin 2. Two corresponding protrusions 5 are arranged in the diametrical direction, and the wire rod 6 can be wound around the winding pin 2 every half rotation of the rotating member 14. Further, on the outer periphery of the central protrusion 15, a pushing member 17 is provided that pushes out the wire 6 wound around the protrusion 15 and transfers it to the winding pin 3.

Further, in the above embodiment, a cylindrical body is illustrated as the rotating body 1, but an endless rotating body such as an endless chain may be used to rotate the rotating body 1 in an elliptical shape. Also, instead of providing two rows of winding pins 2 and 3 on a single rotating body 1, a pair of rotating bodies are provided, each with a winding pin 2 and 3, and the interval between both rotating bodies is adjusted. It is also possible to arbitrarily set the meandering width.

(Effects of the Invention) According to the serpentine wire manufacturing apparatus of the present invention, by synchronously rotating the rotating body and the rotating member as described above, a serpentine wire is formed between the winding pins arranged in two rows on the rotating body. Since a meandering wire can be manufactured by winding the wire around the wire, it is possible to increase the speed and greatly improve production efficiency compared to the case of reciprocating motion.
