Description

The present invention relates to a wire feeder.

Regarding the supply of wire rods at a manufacturing site, conventionally, there is a wire rod supply system that feeds a wire rod to a processing device that automatically measures and cuts the wire rod to a predetermined length. A wire rod for this purpose is wound around a bobbin or the like that serves as a core material to form one wire bundle. When pulling out and supplying the wound wire material from the electric wire bundle, the wire material is devised so that the wire material can be pulled out through many rollers and holes so as not to cause twisting or peculiarities.

As shown in FIG. 15, for example, there is a wire material feeding system in which a pre-feeder 120 is installed between a wire bundle 110 and a terminal crimping machine 130 to feed the wires with a loose mechanism. The terminal crimping machine 130 is a so-called wire processing device, and is equipment for measuring, cutting, and crimping the wire 100 . In the case of feeding the wire with the structure shown in FIG. 15, although the wire is guided along the rollers of the pre-feeder 12, there is a problem that the wire tends to come off the rollers when it moves. In addition, since there is no separate guide member for supporting the direction in which the wire rod 100 is pulled out from the wire bundle 110 and guiding the wire rod, it has been considered difficult to arrange a plurality of wire bundles in a row. If it becomes difficult to arrange a plurality of wire bundles, and if all the wire rods 100 for one bundle wound around the core material are pulled out, preparations such as replacement with a new wire bundle 110 will be required each time, resulting in work efficiency. decreases.

Therefore, for the purpose of efficiently supplying wires, there is a supply system that enables continuous supply of wires by arranging multiple wire bundles in advance and connecting the ends of each wire bundle. do. For example, by providing a belt-like transport mechanism for wire bundles, and arranging a plurality of wire bundles in the longitudinal direction of the transport mechanism so that the wire bundles can be moved in a certain direction, the wire bundle can be wound around the first wire bundle. When the wire rod is pulled out to the end, the transport mechanism operates, and the wire rod is pulled out from the next wire bundle in the same position. There are those with a mechanism that allows the position of the wire to be drawn out variable, and those with a mechanism that has a component that regulates the movement of the wire and continuously draws out the wire from a plurality of wire bundles. In either case, when the wire rod of the first wire bundle is pulled out, the wire rod can be pulled out from the next connected wire bundle.

In addition, when the wire is pulled out from the wire bundle and sent to the processing device, it is necessary to properly supply the wire while preventing the wire from getting entangled. Some have the function of suppressing the occurrence of entanglement.

However, in either case, it is necessary to arrange the wire bundles at a predetermined position and number, and it is not suitable for changing the number of wire bundles to be arranged according to the situation. When an arbitrary number of wire bundles need to be provided, it is necessary to increase the number of members when using a conveying mechanism or another guide member, and it is difficult to increase the number of arranged wire bundles depending on the situation. In addition, when wire restricting parts are used, the operation is restricted regardless of whether or not additional members are added, so it is difficult to arrange an arbitrary number of them.

On the other hand, when the wire rod is pulled out vigorously, the wire bundle moves violently and the wire rod tends to get tangled. It is desirable to have not only rollers but also means for preventing entanglement and means for directing the route followed by the wire so as to prevent twisting and curling. Also, in order to enable long-term use, a mechanism having a complicated system is not suitable, and a simple mechanism that does not use power is required to prevent twisting and entanglement of electric wires.

Therefore, the present embodiment provides a wire feeder having a mechanism capable of continuously feeding wires by arranging an arbitrary number of wire rods regardless of the number of bundles of wire rods to be supplied. In addition, the configuration of the guide guide that directs the path followed by the drawn-out wire makes it possible to switch the supply of the wire through a non-electrical mechanism that uses the power acting on the wire. Wire can be supplied.

According to this, it is possible to significantly reduce the work time for preparation and installation, and it is possible to reduce the equipment stoppage time due to entanglement and clogging, and it is possible to effectively suppress the reduction in work efficiency. .

In the following, a configuration for supplying a wire rod to a processing device will be described with respect to the wire rod feeding device of the present embodiment.

FIG. 1 is a diagram showing the configuration of a wire feeder 10. As shown in FIG. The wires supplied in this embodiment are wire bundles wound around a bobbin that serves as a core material. The wire is let out from above the wire bundle and supplied to the processing device via the wire supply device 10 .

The wire feeder 10 is composed of a support 11 and an entanglement preventing means 12 . The column 11 is erected approximately perpendicularly to the floor, and is supported by the floor by means of a support stand, a weight, or the like (not shown). The strut 10 is desirably cylindrical so that it can move smoothly in the circumferential direction. As a result, the post 11 serves as the axis of the wire rod supply device 10, and can stabilize the center of gravity even if a certain amount of force is applied from the outside. The entanglement prevention means 12 includes a umbrella 13 having two openings 13a and 13b, one of which is approximately the same size as the outer diameter of the wire bundle, and a support arm that rotatably connects the umbrella 13 to the support 11. 14, and a guide 15 that regulates the movement of the drawn-out wire and directs the route to a processing device (not shown).

The umbrella 13 has a shape similar to a truncated cone, does not have two bottom surfaces, a lower surface and an upper surface, but has openings 13a and 13b, and only the side surfaces are formed using a material such as polypropylene. As the material of the umbrella 13, general plastics and other resins can be used as long as the ends and edges are not sharp.

The opening 13a has a diameter substantially equal to the outer diameter of the wire bundle, and the opening 13b has a smaller diameter than the opening 13a. The umbrella 13 assumes a cup-like shape that widens towards one edge, and may consist of an upside down cup without a bottom. Alternatively, a conical instrument having two openings in advance, such as a funnel, may be used as long as it has a shape in which one aperture is narrowed. Alternatively, even if it has a bottom, it may have an alternative to the opening 13b, for example, by forming a penetrating hole. However, it is assumed that the hole has a diameter that allows the wire to pass through with a margin.

The umbrella 13 is attached to the support arm 15 so that the larger opening 13a faces downward and the smaller opening 13b faces upward. At this time, by attaching the umbrella 13 so that the surfaces of the openings 13a and 13b are at an angle with respect to the floor surface and inclined outward from the pillars 11, the opening 13b is more inclined than the opening 13a. It can be arranged so that the part is close to the support on the projection plane. However, as shown in FIG. 2, the opening 13b may be positioned approximately right above the opening 13a. By doing so, it is possible to limit the direction of the wire when it is pulled out.

The diameter of the opening 13a is substantially the same as the diameter of the bundle of electric wires around which the wires are wound and stored. As a result, the path followed by the wire drawn out from the upper portion of the wire bundle is appropriately restricted, making it difficult for the wire to become entangled. The umbrella 13 does not have to be a truncated cone as shown in FIG. Alternatively, the shape of the umbrella 13 is not limited as long as it has openings 13a and 13b. In either case, at least the top and bottom should have openings through which they can be inserted. Therefore, as long as it has two openings 13a and 13b, it is not limited to having an inner wall surface. As shown at least in FIG. I don't mind.

The guide 15 has a through hole 15a through which a wire is passed, and is attached to the column 11 so as to be rotatable in the circumferential direction. The through hole 15 a is provided at a position closer to the axis of the support 11 than the openings 13 a and 13 b of the umbrella 13 .

Therefore, in the entanglement preventing means 12, the openings 13a and 13b of the umbrella 13 and the through hole 15a of the guide 15 through which the wire is inserted are arranged such that the point closest to the support is the through hole 15a, the opening 13b, the opening 13b, It becomes the opening 13a. That is, the distance d1 from the post to the through hole 15a, the distance d2 from the post to the opening 13b, and the distance d3 from the post to the opening 13a are increased in this order. In this way, it is possible to regulate the position at which the drawn wire rod is sent out. The wire passed through the through-hole 15a is sent to a wire-processing device via, for example, a roller (not shown) provided above the through-hole 15a on the extension line of the support. In order to keep the supply stability and effectively prevent the wire rod from coming off the roller, the through hole 15a immediately in front of the roller is arranged at the position closest to the support.

Next, the relationship between the wire feeder 10 and the arrangement of the surrounding wire bundles will be described. FIG. 5 is a diagram showing the arrangement of the wire feeder and the wire bundle, and FIG. 6 is a top view of FIG.

A section 20 for arranging a bundle of electric wires is provided around the wire feeder 10 . Although shown as a partition 20 here for convenience, the size, shape, and the like may be determined as appropriate. In the compartment 20, it is possible to clarify where the wire bundles A, B, C, and D in the packing box are to be arranged. In addition, although the division 20 is set as the arrangement range, a stand for the wire bundle is not essential, so the number of parts constituting the wire rod supply device can be reduced, resulting in a simpler and easier-to-use shape. The wire bundles A, B, C, and D all have the same wire wound around them, and the umbrella 13 is placed in the immediate vicinity of the wire bundle A supplied first or closer to the post 11 than it. The electric wire bundles A, B, C, and D are separated from the support 11 by an equal distance from the support 11. - 特許庁

As for the connection relationship of the respective wire bundles, wire bundles A, B, C, and D in which wire rods are maintained in a wound form are attached in advance to the ends of the next wire bundle. The end of the first wire bundle A and the tip of the second wire bundle B are connected with tape or the like, and the end of the second wire bundle B is also connected to the tip of the next third wire bundle C. Connecting. When all the wire bundles are connected in this manner, a single long wire rod 1 in which the winding end and the winding start are continuous from the end A1 to the end D2 is obtained. Moreover, as shown in FIG. 6, it is preferable to provide a notch portion 21 or the like in the box for packing the wire bundle. By arranging the wire so as to hook it on the notch 21, it is possible to prevent the entanglement of the part pulled out to the wire supply device and the part connected to the next wire bundle.

From now on, with reference to FIG. 7, the operation of the supply flow of the linear member in the wire supply device will be described.

First, the wire 1 is passed through the umbrella 13 from below (opening 13 a ) to above (opening 13 b ) and through the through hole 15 a of the guide 15 . The wire 1 coming out of the through hole 15a is supplied to a wire processing device (not shown) through a roller or the like (step I). The wire rod 1 enters through the opening 13a of the umbrella 13 having a diameter approximately equal to the diameter of the wire bundle, follows the inner wall surface of the umbrella 13, and exits to the opening 13b on the opposite side. When one electric wire bundle A has been drawn out, the tangling prevention means 12 positioned approximately above the electric wire bundle A that has been supplied until then is pulled toward the electric wire bundle B whose ends are connected (step II ), which is located above the wire bundle B (step III). In this way, when the wire rod is fed out from the bundle of wires arranged at a fixed position, the tensile force of the wire rod is applied to pull the wire rod around the bundle of wires to be supplied. It operates circumferentially as an axis. Steps I to III are repeated, and the wire bundle B is followed by the wire bundle C, and then the wire bundle D. By moving the entanglement prevention means 12 in the circumferential direction of the support column 11, four wire bundles A, B, C, and It becomes possible to continuously supply the wire 1 of D. As a result, the entanglement preventing means 12 is pulled in the circumferential direction around the support 11 each time the bundle of electric wires changes, and moves in the same direction to move 360° at the maximum to make one turn.

As described above, the wire rod 1 can be supplied to the processing device by performing the work of feeding through the wire rod feeding device 10 in steps I to III. The sheath 13 of the entanglement prevention means 12 is automatically placed on top of the next bundle of wires by the tension of the wire 1, and the wire 1 follows the inner wall surface of the sheath 13 to prevent the wire from being swayed by the tension from the wire processing device. It is possible to suppress the entanglement of the wire and prevent the entanglement of the wire.

Here we present another mechanism by which the objective can be achieved. For example, as shown in FIGS. 8 and 9, of the entanglement preventing means 12, the umbrella 16 may be provided directly on the column 11. FIG. Both of FIGS. 8 and 9 are assumed to have two openings. The umbrella 16 integrates the functions of the umbrella 13 and the support arm 14 in FIG. At this time, as in FIG. 1, a guide 15 for controlling the direction of the wire rod 1 is provided on the upper part of the post 11, and a plurality of wire bundles are arranged directly below or outside the track, which is the movement range of the umbrella 16. By doing so, the wire rod 1 can be sent to the processing device via the rotatable umbrella 16 and the guide 15 . By using these configurations, it is possible to reduce the number of parts required to establish the wire rod supply device 10 .

In addition, the umbrella 13 may be made of an umbrella-like spring or other material, and when a spring is used, it has elasticity and functions to release the force applied to the wire rod 1 when it is pulled upward. In addition, even if the wires of the wire bundle collide with the umbrella 13 because the wires of the wire bundle are pulled while entangled, they can be easily shaken off by the elasticity, and the occurrence of entanglement due to violent movement of the wire bundle, so-called fluttering, can be suppressed. .

Further, as shown in FIG. 10, a mechanism may be provided in which a shade 17 extends up to the vicinity of the top of the post 11 . The entanglement preventing means 12 may not be composed of the guide 15 and the sheath 18 as described above, but may be an integral type. The umbrella 17 has openings 17a and 17b. The opening 17b is open to the extent that the wire rod can be inserted. has the same role as By using this configuration, the number of parts is smaller than that in FIGS. 8 and 9, and it is possible to reduce labor for inspection and replacement.

Next, a method for arranging the wire bundle will be described. In this embodiment, four wire bundles are arranged, but the number can be set arbitrarily as long as it can be arranged around the support, so two, three, five, etc. may be used. In this case, it is better if they can be arranged substantially symmetrically with respect to the support so that the distances from the support to each wire bundle are substantially the same.

11 and 12 are examples of a method of arranging a plurality of wire bundles, and are plan views seen from above with respect to the floor surface. Here, it is assumed that the wire feeder is configured without support arms. A bundle of electric wires is arranged directly under the track, which is the moving range of the umbrella 16. - 特許庁In order to arrange them almost immediately below the track, it is desirable that they are positioned symmetrically with the support 11 as the center. 11 shows how the wires are arranged in the packing box, and FIG. 12 shows how the wire bundles are arranged after being taken out of the packing box. In either case, the plurality of wire bundles are arranged so that they do not come into contact with each other. In this manner, since a plurality of wire bundles can be freely arranged under predetermined conditions, it is possible to appropriately consider the arrangement location according to the type and situation of wire rods. Also, if a plurality of wire bundles can be arranged, the length of wire that can be supplied at one time is increased, and the frequency of replacement and preparation of wire bundles by workers is reduced.

In addition, as for the arrangement position of the bundle of electric wires, it was explained earlier that it is arranged on the outside of the umbrella rather than directly under the umbrella. It is even better to arrange the wire bundle approximately on the extension line of the height 13 . In other words, the entanglement preventing means 12 are provided so as to overlap with the axis of the path along which the wire rod 1 is pulled out. The wire bundle, umbrella 13, and guide 15 are coaxially present. The arrangement of the wire bundle can be arbitrarily adjusted according to the angle of the umbrella 13 and the openings 13a and 13b. According to this, it is possible to reduce the possibility of twisting or other peculiarities occurring compared to the case of arranging directly below. When the electric wire bundles are arranged at a position away from the support 11 in this way, a plurality of electric wire bundles are arranged in a donut shape with the support 11 as an axis. can be placed. Moreover, since there is no need to add a special member, it is possible to freely determine the number of wire bundles to be arranged. The end and start ends of each are connected.

Alternatively, as shown in FIG. 14, a method of arranging the wire bundles in a stepped pattern may be used. According to this, the number and positions of the wire bundles suitable for arrangement are clarified, and the worker's time and effort to consider when arranging can be eliminated.

As described above, according to the wire feeder of the present embodiment, a plurality of wire bundles are arranged at once, and the tangle prevention means functions smoothly without causing problems even when the wire bundles are switched during supply. Therefore, it is possible to properly pull out the wires from the plurality of wire bundles while preventing entanglement, etc., and supply them to the processing device. In addition, the number and position of wire bundles to be set can be arbitrarily determined according to the type of wire, the size of the wire bundle, the space that can be arranged, the work frequency of the operator, etc., so there is sufficient versatility. In this way, it is possible to improve the supply efficiency of the wire rods, and more accurately process a large number of wire rods.

In addition, since the wire rod feeding device of the present embodiment does not require power, it is possible to realize smooth wire rod feeding without a more complicated mechanism than in the conventional example. Furthermore, by selecting the configuration of the entanglement prevention means according to the installation situation, it is possible to reduce the arrangement range of the wire bundle, and it is possible to apply it even when the area is limited.

All embodiments of the invention are provided by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and modifications can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the scope of the invention described in the claims and equivalents thereof.
