Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the conventional technologies represented by the aforementioned Patent Documents 1 to 3 did not include any configurations for automating the wire laying process. Therefore, in the field of wire laying technology, there was a need for methods and automated devices that could perform the wire laying process efficiently without requiring manual labor.

[0006] Therefore, the present invention aims to provide a method for efficiently performing the wiring work of storing multiple electric wires in predetermined grooves without requiring manual labor, and to realize an automatic wiring device for performing this method. [Means for solving the problem]

[0007] The present invention provides a method for storing multiple electric wires in a predetermined groove, using an automatic wire laying device that includes a chuck consisting of two guides for moving multiple electric wires of different diameters without gripping them, and a pusher positioned between the two guides for pushing the multiple electric wires out of the chuck, wherein the gap between the two guides of the chuck is wider than the diameter of the thickest electric wire among the multiple electric wires and narrower than twice the diameter of the thinnest electric wire among the multiple electric wires, and the gap on the side of the chuck that pushes out the multiple electric wires is elastic. The chuck is characterized by the following steps: first step, the chuck is closed by an elastic baffle plate such that the gap is narrower than the diameter of the thinnest of the multiple wires, the gap of the chuck is closed by an elastic baffle plate such that the diameter of the multiple wires is narrower than the diameter of the thinnest of the multiple wires, and the chuck is moved onto the predetermined groove, and then the pusher positioned between the two guides pushes the multiple wires that are lined up in a row, thereby pushing aside the elastic baffle plate that closes the gap on the side of the chuck from which the multiple wires are pushed out, pushing out one wire, and storing the one wire in the predetermined groove, and the operation of the second step is repeated.

[0008] In other words, in the case of a wire bundle containing multiple wires of different diameters, a chuck consisting of two guides cannot grip them. However, in the method of the present invention, the gap between the two guides of the chuck is kept wider than the diameter of the thickest wire among the multiple wires, and narrower than twice the diameter of the thinnest wire among the multiple wires. Therefore, even if the multiple wires are not gripped by the two guides of the chuck, the alignment order of the wires will not be changed.

[0009] Furthermore, in the present invention, the gap on the side of the chuck that pushes out multiple wires is closed by an elastic baffle plate, and this closed state is narrower than the diameter of the thinnest wire among the multiple wires. Therefore, multiple wires arranged in a line between the two guides will not fall out under normal circumstances, and when pushed by the pusher, the elastic baffle plate deforms so that the wires can be pushed out one by one.

[0010] The present invention provides an automatic wire laying device comprising a chuck consisting of two guides for moving multiple electric wires without grasping them, and a pusher for pushing out the multiple electric wires which are arranged in a line between the two guides, wherein at least one of the two guides has an elastic baffle plate with elastic force that protrudes so as to obstruct the direction in which the multiple electric wires are pushed out at an oblique angle, and the device also comprises an extrusion mechanism for pushing out the multiple electric wires which are arranged in a line between the two guides one by one with the pusher.

[0011] Furthermore, in the automatic wire laying device according to the present invention, the elastic baffle plates are placed at the tip of each of the two guides for moving the plurality of electric wires without grasping them, and the combined arrangement of the two guides and the two elastic baffle plates can be a line-symmetrical shape with respect to the trajectory of the pusher as the axis of symmetry. [Effects of the Invention]

[0012] According to the present invention, it is possible to realize a method for efficiently performing the wire laying work of storing multiple electric wires in predetermined grooves without requiring manual labor, and an automated wire laying device that performs this method.

Embodiments for Carrying Out the Invention

[0014] Preferred embodiments for carrying out the present invention will be described below with reference to the drawings. In the drawings, the first, second, and third directions are defined for convenience of explanation. In this specification, the first direction is the front-back direction. In the drawings, the front-back direction is indicated as the X direction. Specifically, the front is the +X direction and the rear is the -X direction. In this specification, the second direction is the left-right direction. In the drawings, the left-right direction is indicated as the Y direction. Specifically, the right is the +Y direction and the left is the -Y direction. Furthermore, in this specification, the third direction is the up-down direction. In the drawings, the up-down direction is indicated as the Z direction. Specifically, the up is the +Z direction and the down is the -Z direction. However, the first direction (X direction), the second direction (Y direction), and the third direction (Z direction) as defined in this specification do not limit the direction in which the automatic cable laying device 30 according to this embodiment can be used. The automatic cable laying device 30 according to this embodiment can be used in any direction.

[0015] Furthermore, the following embodiments are not intended to limit the invention as described in each claim, and not all combinations of features described in each embodiment are necessarily essential to the solution of the invention.

[0016] Referring to Figures 1 to 12, the mechanism for carrying out the present invention method for storing multiple electric wires 11 in a predetermined groove 21 will be described. As shown in Figure 1, the mechanism includes a cable 10 in which multiple electric wires 11 are bundled together, a wire laying jig 20 for temporarily placing the multiple electric wires 11, and an automatic wire laying device 30 that temporarily places the multiple electric wires 11 on the wire laying jig 20 and performs the wire laying work.

[0017] In this embodiment, the cable 10 is formed by bundling multiple electric wires 11 together and covering their outer circumference with a covering material. The multiple electric wires 11 that make up the cable 10 include multiple types of electric wires 11 with different diameters.

[0018] As shown in Figure 2, the wiring jig 20 is a cube-shaped component with multiple grooves 21 formed on its upper surface. Each of the multiple grooves 21 is designed to accommodate one of the multiple electric wires 11 that make up the cable 10. The multiple grooves 21 are formed at the same pitch interval as the terminal pitch of a connector (not shown) to which the electric wires 11 are connected after the wiring work is completed. Therefore, the wiring work is completed by arranging the multiple electric wires 11 one by one in a predetermined order in the multiple grooves 21 of the wiring jig 20.

[0019] The automatic wire laying device 30 functions as a device that automatically performs the wire laying work described above. The automatic wire laying device 30 according to this embodiment includes a chuck unit 31, a chuck 32 consisting of two guides 32a and 32b, a pusher 33, and a cylinder 34 that serves as a drive source for the pusher 33.

[0020] The chuck unit 31 is the main unit of the automatic wiring device 30, to which a chuck 32 consisting of two guides 32a and 32b, a pusher 33, and a cylinder 34 are attached. An external power supply, control device, and drive device (not shown) are connected to the chuck unit 31. In other words, the chuck unit 31 controls the operation of the chuck 32 consisting of the two guides 32a and 32b, the pusher 33, and the cylinder 34 by receiving power from an external power supply (not shown) and operation command signals from a control device (not shown). Furthermore, the chuck unit 31 is movable by a drive device (not shown), and its relative position to the wiring jig 20 can be changed.

[0021] The chuck 32 is equipped with two guides, a first guide 32a and a second guide 32b. When the chuck unit 31 is viewed from the front, the first guide 32a is located on the left side and the second guide 32b is located on the right side. The two guides 32a and 32b are configured to move in opposite directions to each other. Therefore, to widen the gap of the chuck 32, the left-side first guide 32a moves to the left (i.e., in the -Y direction), and the right-side second guide 32b moves to the right (i.e., in the +Y direction), resulting in the state shown in Figures 1, 11, and 12. On the other hand, to narrow the gap of the chuck 32, the left-side first guide 32a moves to the right (i.e., in the +Y direction), and the right-side second guide 32b moves to the left (i.e., in the -Y direction), resulting in the state shown in Figures 3 to 10.

[0022] Furthermore, as shown in Figures 3 to 6, even when the two guides 32a and 32b are closed with multiple wires 11 sandwiched in the gap of the chuck 32, the chuck 32 does not grip the multiple wires 11. Therefore, the multiple wires 11, which are arranged in a vertical line between the two guides 32a and 32b, can move in the vertical direction.

[0023] The pusher 33 is a flat plate-shaped member that can move vertically through the gap of the chuck 32 when the two guides 32a and 32b are closed. A cylinder 34, which is the driving source for the pusher 33, is positioned above the pusher 33. The cylinder 34 operates by receiving compressed air from an air pump (not shown), which can move the pusher 33 up and down. As is clear from comparing Figures 6 and 10, the lower end of the vertically moving pusher 33 can push out the multiple electric wires 11 that are sandwiched in the gap of the chuck 32 and arranged in a vertical line downwards. The extrusion mechanism of the present invention is composed of the pusher 33 and the cylinder 34.

[0024] As shown in Figure 6, elastic baffles 35a and 35b, which have elastic force and protrude diagonally to obstruct the direction in which the multiple electric wires 11 are pushed out (i.e., downwards) at the ends of the two guides 32a and 32b, respectively. The elastic baffles 35a and 35b are flat plate-shaped members, and each of the two elastic baffles 35a and 35b is firmly fastened to the two guides 32a and 32b by bolts 36. Furthermore, in the automatic wire laying device 30 according to this embodiment, the arrangement shape of the two guides 32a and 32b and the two elastic baffles 35a and 35b is configured to be symmetrical with respect to the trajectory of the pusher 33 as the axis of symmetry (shown as the dashed line α in Figure 6).

[0025] Furthermore, in the automatic wire laying device 30 according to this embodiment, the gap between the chuck 32, which consists of two guides 32a and 32b, is kept wider than the diameter of the thickest wire among the multiple wires 11, and narrower than twice the diameter of the thinnest wire among the multiple wires 11. In addition, the gap on the side of the chuck 32 that pushes out the multiple wires 11 is closed by elastic baffles 35a and 35b that have elastic force so that it is narrower than the diameter of the thinnest wire among the multiple wires 11.

[0026] With the above configuration, as shown in Figure 6, when multiple wires 11 are lined up in a row in the gap of the chuck 32, the multiple wires 11 are not gripped in the gap of the chuck 32 but remain movable in the vertical direction, while the lowest wire 11 is closed off below by the two elastic baffles 35a and 35b. Furthermore, even if the multiple wires 11 are not gripped by the chuck 32 consisting of two guides 32a and 32b, the alignment order of the wires 11 does not change. Therefore, the multiple wires 11 can be stably maintained in a line between the two guides 32a and 32b.

[0027] As shown in Figure 6, when the cylinder 34 is operated to move the pusher 33 downwards, the multiple electric wires 11, which are lined up in a row between the two guides 32a and 32b, are pushed out one by one by the pusher 33, as shown in Figure 10. At this time, all of the multiple electric wires 11 are pushed downwards by the pusher 33, but the groove depth of the groove 21 formed on the upper surface of the wire laying jig 20 corresponds to the wire diameter of the lowest electric wire 11. Therefore, only the lowest electric wire 11 pushes aside the elastic baffles 35a and 35b and is pushed out, and that single electric wire 11 is stored in the predetermined groove 21. At this time, the wires 11 other than the one wire 11 that has been pushed out and stored in the groove 21 are prevented from being pushed downward by the elastic baffles 35a and 35b, so that they remain aligned in a line between the two guides 32a and 32b. When the cylinder 34 is operated from the state shown in Figure 10 to return the pusher 33 to its original upper position, the automatic wire laying device 30 according to this embodiment returns to the state shown in Figure 6. From this state, the chuck unit 31 is moved by a drive device (not shown) to move the pusher 33 to the position of the next groove 21, and the cylinder 34 is operated again to move the pusher 33 downward, thereby storing one wire 11 in the next groove 21. By repeating the above operations, as shown in Figures 11 and 12, all the wires 11 can be stored in the multiple grooves 21 of the wire laying jig 20, and the wire laying work by the automatic wire laying device 30 of this embodiment can be completed.

[0028] The mechanism for implementing the present invention method of storing multiple electric wires 11 in a predetermined groove 21 has been described above using Figures 1 to 12. Next, with reference to Figure 13, the specific procedure for the present invention method of storing multiple electric wires 11 in a predetermined groove 21 will be described.

[0029] In the present invention, a method for storing multiple electric wires 11 in a predetermined groove 21, first, the insulation of the cable 10 is stripped to separate the multiple electric wires 11 so that they are arranged in a vertical line (step S10). At this time, the order in which the multiple electric wires 11 are arranged is such that they are stored in the groove 21 in order from the bottom upwards.

[0030] Next, the multiple wires 11 arranged in a vertical line are inserted into the gap of the chuck 32, so that the multiple wires 11 are arranged in a line within the gap of the chuck 32 (step S11; state shown in Figure 1). From this state, the chuck is closed (step S12). At this time, the multiple wires 11 arranged in a vertical line between the two guides 32a and 32b are not gripped by the chuck 32 and can move up and down (same state as Figure 6). For the multiple wires 11 in this state, the gap of the chuck 32 consisting of the two guides 32a and 32b is kept wider than the diameter of the thickest wire among the multiple wires 11, and narrower than twice the diameter of the thinnest wire among the multiple wires 11. Therefore, even though the multiple wires 11 are not gripped by the chuck 32 consisting of the two guides 32a and 32b, the order in which the wires 11 are arranged does not change. Furthermore, the gap in the chuck 32 that pushes out the multiple wires 11 is closed by elastic baffles 35a and 35b, which have elastic force, so that it is narrower than the diameter of the thinnest wire among the multiple wires 11. In this state, the multiple wires 11 are not gripped by the gap in the chuck 32 and remain freely movable in the vertical direction, while the wire 11 located at the bottom of the multiple wires 11 is closed off below by the two elastic baffles 35a and 35b.

[0031] Steps S11 to S12 correspond to the first step of the method of the present invention. Steps S10 to S11 may be performed manually by an operator, or by using a robot hand or other work means (not shown). Furthermore, the processing from step S12 onward is performed by the automatic wire laying device 30 of this embodiment.

[0032] Step S12 moves the chuck 32, with its two guides 32a and 32b closed, to a predetermined groove 21 among the multiple grooves 21 formed on the upper surface of the wiring jig 20 (Step S13; state shown in Figures 3 to 6). The movement of the chuck 32 to the predetermined groove 21 is performed by a drive device (not shown) connected to the chuck unit 31.

[0033] Next, a pusher 33 positioned between the two guides 32a and 32b pushes the multiple wires 11 arranged in a vertical line downward (step S14; state shown in Figures 7 to 10). The downward movement of the pusher 33 in step S14 is driven by a cylinder 34 positioned above the pusher 33, which receives compressed air from an air pump (not shown).

[0034] As the pusher 33 moves downward and pushes down on the multiple wires 11 arranged in a vertical line, it pushes aside the elastic baffles 35a and 35b that close the gap on the side of the chuck 32 that pushes out the multiple wires 11, causing the elastic baffles 35a and 35b to deform and push out the bottommost wire 11. This action causes the single wire 11 to be housed in the predetermined groove 21 (step S15; see Figure 10 in particular). In the embodiment of Figure 10, the arrangement of the two guides 32a and 32b and the two elastic baffles 35a and 35b is configured to be symmetrical with respect to the trajectory of the pusher 33, so that even if the diameters of the multiple wires 11 are different, the pusher 33 can push the center of each wire 11 into the center of the groove 21, thus ensuring good operation.

[0035] At this time, when the pusher 33 pushes the multiple electric wires 11 downwards, all of the multiple electric wires 11 are pushed downwards. However, since the groove depth of the groove 21 formed on the upper surface of the wire laying jig 20 corresponds to the wire diameter of the single electric wire 11 located at the bottom of the multiple electric wires 11, only the single electric wire 11 located at the bottom is pushed out by the elastic baffles 35a and 35b, and this single electric wire 11 is housed in the predetermined groove 21 (step S15). At this time, the electric wires 11 other than the single electric wire 11 that has been pushed out and housed in the groove 21 are prevented from being pushed downwards by the release of the deformation of the elastic baffles 35a and 35b, so that they remain aligned in a line between the two guides 32a and 32b.

[0036] After the process in step S15 is executed, the cylinder 34 is operated to return the pusher 33 to its original upper position (step S16). Upon execution of step S16, the automatic wire laying device 30 according to this embodiment returns to the state shown in Figure 6. Note that the processes from steps S13 to S16 correspond to the second step of the present invention.

[0037] Once the process in step S16 is complete, a control device (not shown) connected to the chuck unit 31 determines whether the number of times the electric wire 11 has been extruded has reached a predetermined number (step S17). If the number of times the electric wire 11 has been extruded has not reached the predetermined number (N in step S17), the chuck unit 31 is moved by a drive device (not shown), and the chuck 32 moves to the position of the next groove 21 (step S13; state in Figures 3 to 6). In other words, the process from step S13 to step S16 is repeated once more. This repeated operation of the second step (steps S13 to S16) is performed until the number of times the electric wire 11 has been extruded reaches a predetermined number.

[0038] Then, when the number of times the electric wire 11 is pushed out reaches a predetermined number (Y in step S17), the chuck 32 is released and the chuck unit 31 retracts to its initial position (step S18; state shown in Figures 11 and 12). In this way, a series of operations for the method of storing multiple electric wires 11 in a predetermined groove 21, which is the method of the present invention, is completed.

[0039] Although preferred embodiments of the present invention have been described above, the technical scope of the present invention is not limited to the embodiments described above. Various modifications or improvements can be made to the above embodiments.

[0040] For example, in the embodiment described above, as shown in Figures 6 and 10, elastic baffles 35a and 35b with elastic force that protrude diagonally to obstruct the direction in which the multiple electric wires 11 are pushed out were placed at the tip of each of the two guides 32a and 32b on the side that pushes out the multiple electric wires 11 (i.e., the downward side). In other words, one elastic baffle 35a and 35b was installed for each of the two guides 32a and 32b, for a total of two elastic baffles 35a and 35b. However, in the automatic wiring device according to the present invention, it is sufficient to have one elastic baffle 35a installed for at least one of the two guides. An example of such a modified form is shown in Figure 14. Figure 14 shows a specific example in which one elastic baffle 35a is installed only for the first guide 32a. Even with the automatic wiring device configured as shown in Figure 14, the same effects and advantages as the automatic wiring device 30 described above can be achieved.

[0041] For example, in the embodiment described above, the drive source for moving the pusher 33 up and down was a cylinder 34, and this cylinder 34 was operated by receiving compressed air from an air pump (not shown). However, the drive source for the pusher of the present invention can be anything that can move the pusher up and down. For example, a servo motor can be used as the drive source for the pusher 33. By using a servo motor as the drive source, the range of movement of the pusher 33 can be controlled, so it becomes possible to control the amount of movement of the electric wire 11 pushed towards the groove 21, and the load on the electric wire 11 placed in the groove 21 due to the pushing force can be reduced.

[0042] Furthermore, in the embodiment described above, for example, the wiring jig 20 was fixed, and it was assumed that the automatic wiring device 30 would move to position the wiring jig 20 relative to the groove 21. However, the positioning of the wiring jig 20 and the automatic wiring device 30 can be done by either one moving. In other words, the wiring jig 20 may move relative to the fixed automatic wiring device 30 to perform the positioning, or both the wiring jig 20 and the automatic wiring device 30 may move to perform the positioning.

[0043] It is clear from the claims that such modified or improved forms may also fall within the technical scope of the present invention. [Explanation of Symbols]
