Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the wire supply device described in Patent Document 1 suppresses wire supply using a ceramic roller and a spring, and the wire is supplied so as to pass through the upper and lower rollers. Therefore, when the supply direction is changed, a load is applied to the wire, which may cause kinks in the wire or excessive elongation of the wire.

[0006] Furthermore, in the technology described in Patent Document 1, the wire reels are covered with cylindrical covers to suppress entanglement between wires wound on different wire reels, but because there are no guides for the through-holes, entanglement or kinking may occur in the wires depending on the wire supply speed.

[0007] Thus, in the technology described in Patent Document 1, there is a risk that the quality of the electric wire may deteriorate during the supply of the electric wire. Therefore, one aspect of the present invention suppresses the deterioration of the quality of the electric wire during the supply of the electric wire. [Means for solving the problem]

[0008] To solve the above-mentioned problems, one aspect of the present invention adopts the following configuration. The wire supply machine comprises a wire container, a wire guide, and a wire pipe, wherein the wire container includes a container portion for housing the wire and a lid portion for the container portion, the lid portion having an opening for the wire to be discharged from the wire container, the wire guide is hollow with an open top and bottom surface and includes a tapered portion having a tapered shape that narrows from the bottom side to the top side, the bottom side of the wire guide covers the opening and rests on the lid portion, the top side of the wire guide is connected to an inlet portion which is one end of the wire pipe, and the wire pipe has one or more bent portions between the inlet portion and the outlet portion which is the other end of the wire pipe, each having a bending angle of less than or equal to a predetermined value. [Effects of the Invention]

[0009] According to one aspect of the present invention, it is possible to suppress the deterioration of the quality of electric wires during the supply of electric wires.

[0010] Other issues, configurations, and effects not mentioned above will be clarified by the following description of the embodiments. [Brief explanation of the drawing]

[0012] Embodiments of the present invention will be described in detail below with reference to the drawings. It should be noted that these embodiments are merely one example of how to realize the present invention and do not limit the technical scope of the invention. Furthermore, the shapes depicted in the drawings do not necessarily correspond to the actual dimensions and proportions.

[0013] In a conventional general wire feeder, since there is only one type of wire set, each time the wire type, wire diameter, and / or wire color changes, an operation of replacing the wire set in the wire feeder occurs, increasing the working hours in wire processing. If multiple wire feeders are introduced for one wire processing machine, the frequency of wire replacement operations decreases and the working hours are reduced.

[0014] However, since a conventional wire feeder has a rotating mechanism for the purpose of stable wire supply, introducing a plurality of conventional wire feeders incurs high costs. Also, when multiple conventional wire feeders are installed, a large amount of space is required, necessitating a layout change. Moreover, regarding the wire supply device in Patent Document 1, there is no description about the movement of the device, and there is a problem that the movement efficiency is poor when changing the layout of the working place.

[0015] The wire container described later in this embodiment can be used as a wire feeder and a wire storage container, and is a compact and cost-effective product. However, when actually supplying wires directly from the wire container 1 to the wire processing machine, tangling and kinking occur, and there is a problem that it cannot be utilized at a high supply speed such as that of a wire processing machine.

[0016] Therefore, the wire feeder of this embodiment includes a wire container, a wire guide that guides the wire sent out from the wire container to a wire pipe, and a wire pipe that guides the wire sent out from the wire guide to a wire processing machine. The wire guide has a shape that suppresses excessive movement of the wire sent out from the wire container, and the wire pipe is bent at a gentle angle that does not impose a load on the wire. Thereby, in the wire feeder of this embodiment, the wire sent out from the wire container is supplied to the wire processing machine through the wire guide and the wire pipe, enabling stable supply of the wire while suppressing deterioration of the wire quality.

[0017] Furthermore, in this embodiment, multiple wire supply machines are mounted on a specially designed trolley with a stepped shape, as described later, resulting in excellent space efficiency. The work area can be easily moved. In addition, in this embodiment, the parts constituting the wire supply machine are not fixed with special tools, and the wire supply machine and the dedicated trolley are not fixed with special tools, thus reducing the amount of work required to replace the wires stored in the wire supply machine. Moreover, since the dedicated trolley has a coupling part for fixing to the work trolley on which the wire processing machine is mounted, the work area can be easily fixed. [Examples]

[0018] Figure 1 is a perspective view showing an example of a wire processing system 100. The wire processing system 100 includes a wire supply cart 50, a work cart 5, and a wire processing machine 4 installed on the work cart 5. The wire supply cart 50 includes a dedicated cart 10 and one or more (nine in this embodiment) wire supply machines 30. The wire processing machine 4 has a wire intake section 41 for taking in the wire to be processed into the wire processing machine 4.

[0019] The dedicated trolley 10 has a stepped shape, and a wire supply machine 30 can be installed on each step of the dedicated trolley 10. In this embodiment, the dedicated trolley 10 has three steps, and three wire supply machines 30 are installed in a row on each step. For example, the bottom step side of the dedicated trolley 10 faces the side of the wire intake section 41 of the wire processing machine 4.

[0020] One or more rectangular frames 23 are formed at, for example, the lowest end of the dedicated trolley 10. The dedicated trolley 10 has one or more connecting parts 7 that protrude outwards from, for example, the center of the lower edge of the frame 23, and the dedicated trolley 10 and the work trolley 5 are connected and fixed by the connecting parts 7. A wire outlet member 6 is installed on the top or bottom surface at the center of the upper edge of each frame 23, facing the wire intake part 41 of the wire processing machine 4.

[0021] In the wire outlet member 6, for example, multiple wire outlets 21, which are through holes (nine in this embodiment, the same number as the number of wire supply machines 30), are formed at positions facing the wire intake section 41. A spring 8 is provided on the upper side of the frame 23, on the surface facing the wire intake section 41. The dedicated trolley 10 also has multiple casters 11 on its bottom. The wire outlet member 6 (including the inner wall and edge of the wire outlet 21) is made of resin, for example.

[0022] Each of the wire supply devices 30 includes a wire container 1, a wire guide 2, and a wire pipe 3. The wire container 1 houses the wires. Note that the wire container 1 can be used not only as a component of the wire supply device 30, but also as a simple wire storage container. The wire guide 2 is positioned between the wire container 1 and the wire pipe 3. The wire guide 2 guides the wires discharged from the opening 24 of the wire container 1 (described later) to the wire pipe 3.

[0023] The wire pipe 3 is connected to the support column 16 of the wire guide 2, which will be described later. The wire pipe 3 is the path for the wires leading to the wire outlet 21. The wire pipe 3 is also fixed to the wire pipe fixing section 9, which will be described later, provided on the dedicated trolley 10. The ends of the wire pipes 3 of different wire supply machines 30 that are not connected to the wire guide 2 each lead to different wire outlets 21.

[0024] Furthermore, the end of the wire pipe 3 that is not connected to the wire guide 2 is connected to the wire outlet 21. Note that multiple wire pipes 3 leading to the same wire outlet member 6 (or its wire outlet 21) may be bundled together near the wire outlet member 6.

[0025] One end of the electric wire housed in the electric wire container 1 is fed into the interior of the electric wire guide 2 through an opening 24, which will be described later, located on the upper surface of the electric wire container 1. The wire passes through the interior of the electric wire guide 2 and is fed out through an opening 25, which will be described later, located at the upper end of the support column 16 of the electric wire guide 2.

[0026] The end of the electric wire is fed into the electric wire pipe 3 through the opening 25 of the support column 16 of the electric wire guide 2, passes through the inside of the electric wire pipe 3, and heads toward the electric wire outlet 21. Of the electric wires that have passed through the electric wire outlet 21, for example, one electric wire is sent to the electric wire intake section 41 and taken into the electric wire processing machine 4 for processing. The other electric wires that have passed through the electric wire outlet 21 (electric wires that have not been taken into the electric wire processing machine 4) are fixed to the spring 8.

[0027] The wire supply machine 30 will be described below, mainly with reference to Figures 2 to 7. Figure 2 is a perspective view showing an example of a wire container 1. Figure 3A is a plan view showing an example of a wire container 1. Figure 3B is a cross-sectional view showing an example of the cross-sectional structure of the wire container 1 at the AA cutting line in Figure 3A.

[0028] The wire container 1 includes a container section 13 for housing the wire and a lid section 12 which is a lid for the container section 13. The entire wire container 1 or its outer surface is made of, for example, resin. The lid section 12 has a substantially circular planar shape and has an opening 24 in its center for feeding one end of the wire out of the wire container 1.

[0029] As shown in Figure 3B, the lid portion 12 has a recess 14 in the direction toward the container portion 13 at a position between the central portion and the outer circumference of the circle, which is a planar shape. The recess 14 is approximately triangular in cross-section. The container portion 13 has a projection 15 extending from the center of the bottom surface of the container portion 13 toward the lid portion 12.

[0030] The electric wire itself (not wound on a reel, etc.) is arranged inside the electric wire container 1 in an annular (for example, spiral) shape centered on the projection 15. Because the electric wire container 1 has a recess 14 and a projection 15, when the electric wire stored in the electric wire container 1 is fed out from the opening 24, the electric wire is fed out so as to pass between the recess 14 and the projection 15, thereby suppressing excessive movement of the electric wire and, consequently, preventing the occurrence of tangling and kinking of the electric wire.

[0031] Figure 4 is a perspective view showing an example of a wire supply machine 30. Figure 5 is a perspective view showing a partial example of a wire supply machine 30. As mentioned above, the wire supply machine 30 includes a wire container 1, a wire guide 2, and a wire pipe 3.

[0032] The wire guide 2 has a tapered section 26 and a support column 16. The tapered section 26 is, for example, a hollow, roughly conical shape with the apex cut off (a tapered shape that narrows towards the support column 16), and has open top and bottom surfaces. The tapered shape of the tapered section 26 can gradually suppress the movement of the wire discharged from the wire container 1, which is installed in contact with the outer circumference of the bottom surface of the tapered section 26, thereby suppressing the occurrence of wire entanglement and kinking.

[0033] The support column 16 is hollow and has a roughly cylindrical shape with open top and bottom surfaces. The tapered portion 26 and the support column 16 may be manufactured as separate components and bonded or fixed together, or the tapered portion 26 and the support column 16 may be integrally formed as a triangular flask shape with open bottom and top surfaces.

[0034] The wire guide 2 is installed on the wire container 1 such that its tapered portion 26 covers the central part of the lid portion 12 of the wire container 1. The outer circumference of the bottom surface of the tapered portion 26 of the wire guide 2 is formed so that it is in contact with the wire container 1 without any gaps. This makes it easier to suppress excessive movement of the wires discharged from the wire container 1, and in turn, it can suppress the occurrence of wire entanglement and kinking.

[0035] Furthermore, it is desirable that the bottom radius of the tapered portion 26 of the wire guide 2 be determined such that, when the wire guide 2 is placed in the center of the lid portion 12 of the wire container 1, the outer circumference of the bottom of the tapered portion 26 is located inside the most recessed part of the recess 14 of the lid portion 12, or is in contact with the most recessed part.

[0036] Furthermore, the tapered portion 26 of the wire guide 2 and the lid portion 12 of the wire container 1 are neither fixed nor glued to each other; the wire guide 2 simply rests on the lid portion 12 of the wire container 1. This allows the worker to easily separate the wire container 1 and the wire guide 2, thereby facilitating the replacement of electrical wires by the worker.

[0037] Figure 6A is a front view showing an example of a wire guide 2 and a portion of the wire pipe 3. Figure 6B is a cross-sectional view showing an example of the cross-sectional structure of the wire guide 2 and a portion of the wire pipe 3 at the BB cutting line in Figure 6A.

[0038] The wire pipe 3 is a hollow cylindrical shape with open ends. The wire pipe 3 has an inlet portion 18 that connects to the support column 16 of the wire guide 2. The support column 16 of the wire guide 2 is positioned to be in contact with the apex of the tapered portion 26 of the wire guide 2.

[0039] The outer diameter of the support post 16 of the wire guide 2 is smaller than the inner diameter of the wire pipe 3. The support post 16 is inserted into the entrance portion 18 of the wire pipe 3 and forms the contact point between the wire guide 2 and the wire pipe 3. Furthermore, the entrance portion 18 of the wire pipe 3 and the support post 16 of the wire guide 2 are neither fixed nor glued together; the entrance portion 18 of the wire pipe 3 simply rests on top of the support post 16 of the wire guide 2.

[0040] In this way, since no screws or special fasteners are used to secure the wire guide 2 and the wire pipe 3, the wire guide 2 and the wire pipe 3 can be easily separated when the wire pipe 3 is lifted by the worker, thereby facilitating the replacement of electrical wires by the worker.

[0041] Furthermore, because the support column 16 is inserted into the entrance portion 18 of the wire pipe 3, the wires fed out from the opening 25 of the support column 16 of the wire guide 2 do not come into contact with the contour of the bottom of the entrance portion 18 of the wire pipe 3, thus preventing damage to the wires.

[0042] Note that in Figures 4 to 6B, for the sake of explanation, the lower end of the inlet portion 18 is depicted as floating above the tapered portion 26. However, when the support column 16 is fully inserted into the wire pipe 3, the lower end of the inlet portion 18 will be in contact with the apex of the tapered portion 26.

[0043] Figure 7 is a side view showing an example of a wire pipe 3. The wire pipe 3 includes an inlet section 18 which is the entry point for the wire fed out from the opening 25 of the support column 16 of the wire guide 2, and an outlet section 19 which is the exit point for the wire fed out from the wire pipe 3.

[0044] The inlet section 18 and outlet section 19 are both straight and not bent. The straight shape of the inlet section 18 and outlet section 19 of the wire pipe 3 reduces the load on the wire when it is pulled by the wire processing machine 4 or by an operator.

[0045] The electric wire pipe 3 has one or more bent sections 27 between the inlet section 18 and the outlet section 19. When the electric wire supply machine 30 is installed on the dedicated trolley 10, the electric wire pipe 3 is bent once or more to provide one or more bent sections 27 so that the outlet section 19 and the electric wire outlet 21 are connected in a straight line (or, if the outlet section 19 and the electric wire outlet 21 are not directly connected, so that the center of the electric wire outlet 21 is located on the straight extension of the outlet section 19).

[0046] The bending angle 17 at the bent portion 27 is greater than 0.0° and 22.5° or less. By having a small bending angle 17 that is greater than 0.0° and 22.5° or less, the load on the electric wire passing through the electric wire pipe 3 is reduced, and consequently the quality of the electric wire can be maintained. 22.5° is an example of a predetermined value.

[0047] For example, if you want to bend the wire pipe 3 at a 90° angle (that is, if you want the angle between the entrance 18 and the exit 19 to be 90°), if you were to bend the wire pipe 3 at a 90° angle in one go, the wire that has passed through the straight entrance 18 would bend abruptly at the point of the bend, potentially damaging the outer surface of the wire and consequently degrading the quality of the wire.

[0048] Therefore, if you want to bend the electrical conduit pipe 3 at 90°, you don't bend it 90° all at once, but rather bend the electrical conduit pipe 3 little by little at a gentle angle within a certain range. In other words, by providing the electrical conduit pipe 3 with multiple bends 27, each with a bending angle 17 greater than 0.0° and 22.5° or less, and making the sum of the bending angles 17 90°, a 90° bend in the electrical conduit pipe 3 is achieved.

[0049] Furthermore, if the electric wire pipe 3 has multiple bent sections 27, some or all of the bending angles 17 may be different, or they may all be the same. It is desirable that the material of the electric wire pipe 3 be aluminum or the like to improve the processability of bending at the bent sections 27.

[0050] Furthermore, the spacing between the bent portions 27 may be partially or entirely different, or they may all be the same, but it is desirable that the minimum value of the spacing between the bent portions 27 be determined according to the strength of the material of the electric wire pipe 3.

[0051] Furthermore, it is desirable that the length of the straight section of the entrance 18 (i.e., the length from the end of the entrance 18 to the first bent section 27) be longer than the cylindrical height of the support column 16.

[0052] Furthermore, the wire supply machine 30 can be used independently without being installed on the dedicated trolley 10. In this case, the wire itself, not wound on a reel or the like, is stored in the wire container 1, and one end of the wire is passed through the opening 24 of the wire container 1, the tapered section 26 of the wire guide 2, the opening 25 of the wire guide 2, the inlet 18 of the wire pipe 3, and the outlet 19 of the wire pipe 3 in that order. The end that is fed out from the outlet 19 is then set in the wire intake section 41 of the wire processing machine 4, thereby processing the wire.

[0053] Furthermore, when the wire supply machine 30 is used alone, it is desirable that the bending portion 27 be formed such that the direction in which the wire is taken in by the wire processing machine 4 coincides with the direction of the straight shape of the outlet portion 19 of the wire pipe 3, and the wire intake portion 41 of the wire processing machine 4 is located on the extension of the straight shape of the outlet portion 19 of the wire pipe 3, in order to reduce the load on the wire.

[0054] The dedicated trolley 10 will be mainly explained using Figures 8 to 10. Figure 8 is a perspective view showing an example of the dedicated trolley 10 and the work trolley 5 on which the wire processing machine 4 is installed. Figure 9 is a perspective view showing an example of the dedicated trolley 10. Figure 10 is a plan view showing an example of the dedicated trolley 10.

[0055] As mentioned above, the work trolley 5 is connected to and fixed to the dedicated trolley 10 by the coupling part 7 of the dedicated trolley 10. However, if the length of the coupling part 7 protruding from the frame 23 (i.e., the distance between the dedicated trolley 10 and the work trolley 5 when they are connected by the coupling part 7) is too long, the distance between the wire outlet 21 and the wire intake part 41 of the wire processing machine 4 will increase, and there is a risk that the wire will become loose between the wire outlet 21 and the wire intake part 41.

[0056] On the other hand, if the length of the connecting portion 7 protruding from the frame 23 is too short, at least some of the wires discharged from the wire outlets 21 and taken into the wire intake portion 41 may bend at a sharp angle near the wire outlets 21. From these viewpoints, it is desirable that the longitudinal length of the connecting portion 7 be in the range of, for example, 150 to 250 mm.

[0057] The joint 7 fixes the work platform 5 and the dedicated platform 10, thereby fixing the distance and positional relationship between the work platform 5 and the dedicated platform 10. This stabilizes the tension of the electric wires sent out from the electric wire outlet 21 and taken into the electric wire processing machine 4, and consequently suppresses the deterioration of the electric wire quality.

[0058] The connecting portion 7 may be integrally formed with the dedicated trolley 10 (or its frame 23), or it may be manufactured as a separate component and then fixed or bonded to the dedicated trolley 10.

[0059] Furthermore, as mentioned above, the dedicated trolley 10 has a stepped shape. For example, one or more wire container installation sections 20 are formed in a row on each step of the dedicated trolley 10. The wire container installation section 20 may be, for example, a recess for accommodating the bottom of the container section 13 of the wire container 1, or it may be a simple marker indicating the position for installing the wire supply machine 30.

[0060] In particular, as shown in Figure 10, each of the wire container installation sections 20 is formed such that, at least between adjacent steps of the dedicated trolley 10 (more preferably between all steps), the position of the wire container installation section 20 in the left-right direction in Figure 10 (that is, the direction perpendicular to the direction of ascent and descent on the stair treads, and also the direction in which the wire container installation sections 20 are arranged in a single row on the treads) is offset. This makes it possible to avoid interference between the wire pipes 3 of different wire supply machines 30 when a wire supply machine 30 is installed in each of the wire container installation sections 20.

[0061] Furthermore, the dedicated trolley 10 has wire pipe fixing parts 9 located above each of the wire container installation sections 20. As will be described in detail later, the wire pipe fixing parts 9 are positioned such that when the wire supply machine 30 is installed in the wire container installation section 20, the inlet portion 18 of the wire pipe 3 of the wire supply machine 30 is fixed to the notch portion 28 of the wire pipe fixing part 9.

[0062] Since the steps of each level of the dedicated trolley 10 are formed to cover a portion of the area of ​​the wire container installation section 20 on the level below, the size of the dedicated trolley 10 in the direction of ascending and descending stairs becomes more compact, improving space efficiency.

[0063] However, when the electric wire supply machine 30 is installed in the electric wire container installation section 20, the steps of each step of the dedicated trolley 10 must be formed so as not to cover the openings 24 of each electric wire container 1 installed on the lower step (i.e., the inlets 18 of the electric wire pipes 3 in each electric wire supply machine 30).

[0064] In this embodiment, one row of wire container mounting sections 20 is formed on each step of the dedicated trolley 10, but multiple rows of wire container mounting sections 20 may be formed. However, in order to achieve space saving in the ascending and descending direction of the dedicated trolley 10, it is desirable to form one row of wire container mounting sections 20 on each step.

[0065] As mentioned above, the dedicated trolley 10 has multiple casters 11 on its bottom, allowing the operator to easily move the wire processing system 100. It is desirable that each caster 11 be equipped with a locking mechanism. This allows the operator to easily move the wire processing system 100, and during the operation of the wire processing machine 4, the tension of the wires taken into the machine can be stabilized by locking the casters 11 with the locking mechanism, thereby suppressing a deterioration in the quality of the wires.

[0066] Figure 11 is a perspective view showing an example of a wire supply device 30 installed in the wire container installation section 20. The wire pipe fixing section 9 has a notch 28 with a diameter equivalent to the diameter of the inlet 18 of the wire pipe 3. The inlet 18 of the wire pipe 3 of the wire supply device 30 installed in the wire container installation section 20 is fixed to the notch 28.

[0067] Therefore, workers can fix the electrical conduit 3 to the electrical conduit fixing part 9 and remove the electrical conduit 3 from the electrical conduit fixing part 9 with a single touch, without using any special fasteners or tools.

[0068] Figure 12 is a perspective view showing an example of a wire outlet member 6 and a spring 8. In the example in Figure 12, a wire outlet member 6 is provided on each of the two frames 23. The total number of wire outlets 21 provided on the two wire outlet members 6 is nine, which is the same number (or more) as the number of wire supply machines 30 that can be installed on the dedicated trolley 10.

[0069] In Figure 12, of the nine electric wires 22 supplied from the electric wire supply machine 30, eight electric wires 22 are supplied from the electric wire outlet 21 but are not set in the electric wire processing machine 4 (i.e., they are on standby and not in use), and it is possible to hang these eight electric wires 22 on the spring 8.

[0070] Furthermore, the wire hanging section for hanging idle wires 22 that are not in use is not limited to the spring 8 and may be implemented by hooks, clips, etc. Also, in Figure 12, of the nine wires 22 supplied from the wire supply machine 30, the remaining one wire 22 is supplied from the wire outlet 21 and set in the wire processing machine 4.

[0071] The wire outlet 21 has a tapered shape, for example, narrowing from the wire processing machine 4 side to the wire pipe 3 side (that is, narrowing in the opposite direction to the wire feeding direction). If the wire outlet 21 were not tapered but simply cylindrical, and the wire 22 passing through the wire outlet 21 was at an angle, the wire 22 would come into contact with the edge of the outlet portion of the wire outlet 21 at a single point, causing a large force to be applied to the wire 22 and potentially damaging it.

[0072] On the other hand, in this embodiment, because the wire outlet 21 has a tapered shape, even if the wire 22 passing through the wire outlet 21 is at an angle, the wire 22 is fed out along the inner wall of the wire outlet 21, so that no large force is applied to the wire 22, and thus damage to the wire 22 can be suppressed.

[0073] An example of how to use the wire supply cart 50 is described below. The worker brings the wire supply cart 50 and the work cart 5 close together and connects the coupling part 7 to the work cart 5 to secure the wire supply cart 50 and the work cart 5. The method of supplying wires in the wire supply machine 30 is the same as when the wire supply machine 30 is used alone.
