Description

The present invention relates to a method for storing multiple electric wires in a specified groove and an automatic wiring device that carries out this method.

Conventionally, the task of temporarily placing electric wires in grooves with the same pitch as the connector terminal pitch has generally been done manually. Specifically, the task of laying electric wires involves a worker picking up each of the multiple electric wires of different diameters contained in a single cable, visually checking their appearance to determine the type of wire, and storing them in the designated groove. As a result, the traditional task of laying electric wires had the problem of being time-consuming and labor-intensive.

Incidentally, the following Patent Documents 1 to 3 are examples of conventional techniques for handling electric wires. For example, Patent Documents 1 and 2 disclose a mechanism for feeding electric wires one by one in the process of applying a waterproofing material (see Figures 15 and 16). Also, for example, Patent Document 3 discloses a mechanism for arranging electric wires of different diameters in a line (see Figure 17).

Japanese Patent Application Laid-Open No. 10-172361 Japanese Patent Application Laid-Open No. 10-172359 JP 2000-114746 A

However, the conventional techniques represented by the above-mentioned Patent Documents 1 to 3 did not have a configuration for automating the wiring work of electric wires. Therefore, in the technical field of the wiring work of electric wires, there was a demand for a method and an automated device that can automate the wiring work and perform the wiring work efficiently without human labor.

Therefore, the objective of the present invention is to provide a method for efficiently performing the wiring task of storing multiple electric wires in a specified groove without requiring manual labor, and to provide an automatic wiring device that executes this method.

The method of storing a plurality of electric wires in a predetermined groove according to the present invention is a method of storing the plurality of electric wires in a predetermined groove using an automatic wiring device having a chuck consisting of two guides for moving a plurality of electric wires having different diameters without gripping them, and a pusher for pushing the plurality of electric wires arranged between the two guides out of the chuck, and the automatic wiring device is configured such that the gap of the chuck consisting of the two guides is kept wider than the diameter of the thickest electric wire among the plurality of electric wires and narrower than twice the diameter of the thinnest electric wire among the plurality of electric wires, and the gap on the side of the chuck that pushes out the plurality of electric wires is elastically pressed against the chuck. The chuck is closed by an elastic baffle plate having a diameter narrower than the smallest wire diameter among the plurality of wires, and the chuck is closed by an elastic baffle plate having a diameter smaller than the smallest wire diameter among the plurality of wires. The chuck is closed by an elastic baffle plate having a diameter smaller ...

In other words, when a wire bundle contains multiple wires with different diameters, it cannot be gripped by a chuck consisting of two guides. However, in the method of the present invention, the gap between the chuck consisting of two guides 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, so the order in which the wires are arranged is not changed even if the multiple wires are not gripped by a chuck consisting of two guides.

In addition, in the method of the present invention, the gap on the side of the chuck where the multiple electric wires are pushed out is closed by an elastic baffle plate, and this closed state is closed so that the diameter is narrower than the smallest electric wire among the multiple electric wires. Therefore, the multiple electric wires arranged in a row between the two guides will not fall out under normal conditions, and when pushed by the pusher, the elastic baffle plate deforms, allowing the electric wires to be pushed out one by one.

The automatic wiring device according to the present invention is an automatic wiring device comprising a chuck consisting of two guides for moving multiple electric wires without gripping them, and a pusher for pushing out the multiple electric wires lined up in a row between the two guides, and is characterized in that an elastic baffle plate having an elastic force that protrudes so as to block the multiple electric wires obliquely in the pushing direction is disposed at the tip of at least one of the two guides on the side pushing out the multiple electric wires, and further comprising a pushing mechanism for pushing out the multiple electric wires lined up in a row between the two guides one by one with the pusher.

In addition, in the automatic wiring device according to the present invention, the elastic baffle plate is disposed at the tip of each of the two guides for moving the multiple electric wires without gripping them, and the combined arrangement of the two guides and the two elastic baffle plates can be arranged to be symmetrical about the track along which the pusher moves.

The present invention provides a method for efficiently performing the wiring task of storing multiple electric wires in a specified groove without requiring manual labor, and an automatic wiring device for carrying out this method.

The following describes a preferred embodiment for carrying out the present invention with reference to the drawings. In the drawings, a first direction, a second direction, and a third direction are defined for the convenience of explanation. In this specification, the first direction is the front-rear direction. In the drawings, the front-rear direction is shown as the X direction. In particular, the front is the +X direction, and the rear is the -X direction. In addition, in this specification, the second direction is the left-right direction. In the drawings, the left-right direction is shown as the Y direction. In particular, the right is the +Y direction, and the left is the -Y direction. In addition, in this specification, the third direction is the up-down direction. In the drawings, the up-down direction is shown as the Z direction. In particular, the up is the +Z direction, and the down is the -Z direction. However, the first direction, the X direction, the second direction, the Y direction, and the third direction, the Z direction, defined in this specification do not limit the directions when the automatic wiring device 30 according to this embodiment is used. The automatic wiring device 30 according to this embodiment can be used in any direction.

Furthermore, the following embodiments do not limit the inventions according to the claims, and not all of the combinations of features described in each embodiment are necessarily essential to the solution of the invention.

With reference to Figures 1 to 12, a mechanism for carrying out the method of the present invention 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 wiring jig 20 for temporarily placing the multiple electric wires 11, and an automatic wiring device 30 for temporarily placing the multiple electric wires 11 on the wiring jig 20 and performing the wiring work.

In this embodiment, the cable 10 is formed by bundling a number of electric wires 11 and covering the outer circumference with a coating material. The multiple electric wires 11 constituting the cable 10 include multiple types of electric wires 11 with different wire diameters.

As shown in FIG. 2, the wiring jig 20 is a cubic-shaped member with multiple grooves 21 formed on its upper surface. Each of the multiple grooves 21 can accommodate one of the multiple electric wires 11 that make up the cable 10. The multiple grooves 21 are also 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 has been completed. Therefore, the wiring work is completed by placing the multiple electric wires 11 one by one in the multiple grooves 21 of the wiring jig 20 in a predetermined order.

The automatic wiring device 30 functions as a device that automatically performs the above-mentioned wiring work. The automatic wiring 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.

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

The chuck 32 has 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 disposed on the left side and the second guide 32b is disposed on the right side. The two guides 32a and 32b are configured to be able to move in opposite directions, so that when the gap between the chuck 32 consisting of the two guides 32a and 32b is to be widened, the first guide 32a on the left side moves to the left (i.e., in the -Y direction) and the second guide 32b on the right side moves to the right (i.e., in the +Y direction), resulting in the state shown in Figs. 1, 11, and 12. On the other hand, when the gap between the chuck 32 consisting of the two guides 32a and 32b is to be narrowed, the first guide 32a on the left side moves to the right (i.e., in the +Y direction) and the second guide 32b on the right side moves to the left (i.e., in the -Y direction), resulting in the state shown in Figs. 3 to 10.

As shown in Figures 3 to 6, even when the two guides 32a and 32b are closed with multiple electric wires 11 sandwiched in the gap of the chuck 32, the chuck 32 does not grip the multiple electric wires 11, so the multiple electric wires 11 lined up vertically between the two guides 32a and 32b can move up and down.

The pusher 33 is a flat plate-like member that can move up and down through the gap of the chuck 32 when the two guides 32a, 32b are closed. A cylinder 34 that serves as the drive source for the pusher 33 is disposed above the pusher 33. The cylinder 34 is operated by receiving a supply of compressed air from an air pump (not shown), and can move the pusher 33 up and down. As is clear from a comparison of Figures 6 and 10, the lower end of the vertically moving pusher 33 can push downward the multiple electric wires 11 that are sandwiched in the gap of the chuck 32 and aligned in a vertical line. The pusher 33 and the cylinder 34 constitute the extrusion mechanism of the present invention.

As shown in FIG. 6, elastic baffle plates 35a, 35b having elastic force that protrudes obliquely to block the direction in which the multiple electric wires 11 are pushed out are arranged at the tip of each of the two guides 32a, 32b on the side (i.e., the lower side) that pushes out the multiple electric wires 11. The elastic baffle plates 35a, 35b are flat plate-shaped members, and each of the two elastic baffle plates 35a, 35b is firmly fastened and fixed to the two guides 32a, 32b by bolts 36. In addition, in the automatic wiring device 30 according to this embodiment, the arrangement shape of the two guides 32a, 32b and the two elastic baffle plates 35a, 35b is configured to be linearly symmetrical with the track of the movement of the pusher 33 as the axis of symmetry (shown as imaginary line α shown by a dashed line in FIG. 6).

Furthermore, in the automatic wiring device 30 according to this embodiment, the gap of the chuck 32 consisting of the two guides 32a, 32b is kept wider than the diameter of the thickest electric wire among the multiple electric wires 11 and narrower than twice the diameter of the thinnest electric wire among the multiple electric wires 11, and the gap on the side of the chuck 32 that pushes out the multiple electric wires 11 is closed by the elastic baffle plates 35a, 35b that have elastic force so that it is narrower than the diameter of the thinnest electric wire among the multiple electric wires 11.

With the above configuration, in the automatic wiring device 30 according to this embodiment, as shown in FIG. 6, when multiple electric wires 11 are arranged in a row in the gaps of the chucks 32, the multiple electric wires 11 are not gripped in the gaps of the chucks 32 and remain freely movable in the vertical direction, while the lowermost electric wire 11 of the multiple electric wires 11 is closed at the bottom by the two elastic baffle plates 35a, 35b. In addition, even if the multiple electric wires 11 are not gripped by the chuck 32 consisting of the two guides 32a, 32b, the order of the electric wires 11 is not changed. Therefore, the multiple electric wires 11 can be stably maintained in a row between the two guides 32a, 32b.

When the cylinder 34 is operated to move the pusher 33 downward from the state shown in Fig. 6, the multiple electric wires 11 lined up in a row between the two guides 32a, 32b are pushed out one by one by the pusher 33, as shown in Fig. 10. At this time, all of the multiple electric wires 11 pushed downward by the pusher 33 are pushed downward, but since the groove depth of the groove 21 formed on the upper surface of the wiring jig 20 is a depth dimension corresponding to the wire diameter of the electric wire 11 located at the bottom of the multiple electric wires 11, only one of the electric wires 11 located at the bottom is pushed out by pushing aside the elastic baffle plates 35a, 35b, and the single electric wire 11 is stored in the specified groove 21. At this time, the electric wires 11 other than the one electric wire 11 pushed out and stored in the groove 21 are prevented from being pushed downward by the elastic baffle plates 35a, 35b, so that the state of being lined up in a row between the two guides 32a, 32b is maintained. When the cylinder 34 is operated from the state shown in FIG. 10 to return the pusher 33 to its original upper position, the automatic wiring apparatus 30 according to this embodiment returns to the state shown in FIG. 6. From this state, the chuck unit 31 is moved to a position by a driving device (not shown), the pusher 33 is moved to the position of the next groove 21, and the cylinder 34 is operated again to move the pusher 33 downward, so that the one electric wire 11 is stored in the next groove 21. Then, by repeating the above-mentioned operation, all the electric wires 11 are stored in the multiple grooves 21 of the wiring jig 20 as shown in FIG. 11 and FIG. 12, and the wiring operation by the automatic wiring apparatus 30 according to this embodiment can be completed.

The mechanism for carrying out the method of the present invention for storing multiple electric wires 11 in a specified groove 21 has been described above using Figures 1 to 12. Next, the specific steps of the method of the present invention for storing multiple electric wires 11 in a specified groove 21 will be described with reference to Figure 13.

In the method of the present invention for storing a plurality of electric wires 11 in a predetermined groove 21, first, the insulation of the cable 10 is stripped and the plurality of electric wires 11 are unraveled so that the plurality of electric wires 11 are arranged in a vertical line (step S10). At this time, the plurality of electric wires 11 are arranged in the order from the bottom to the top in the order in which they will be stored in the groove 21.

Next, the multiple electric wires 11 arranged in a vertical line are inserted into the gap of the chuck 32, and the multiple electric wires 11 are arranged in a line in the gap of the chuck 32 (step S11; the state of FIG. 1). From this state, the chuck is closed (step S12). At this time, the multiple electric 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 (the same state as FIG. 6). For the multiple electric 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 electric wire among the multiple electric wires 11 and narrower than twice the diameter of the thinnest electric wire among the multiple electric wires 11, so that even if the multiple electric wires 11 are not gripped by the chuck 32 consisting of the two guides 32a and 32b, the order of the electric wires 11 is not changed. In addition, the gap on the side of the chuck 32 where the multiple electric wires 11 are pushed out is closed by the elastic baffle plates 35a and 35b that have elastic force so that it is narrower than the diameter of the thinnest electric wire among the multiple electric wires 11. Therefore, the multiple electric wires 11 in this state are not gripped by the gap of the chuck 32 and remain freely movable in the vertical direction, while the electric wire 11 located at the bottom of the multiple electric wires 11 is closed on the bottom by the two elastic baffle plates 35a and 35b.

The processing from step S11 to step S12 corresponds to the first step of the method of the present invention. The processing from step S10 to step S11 may be performed manually by an operator, or may be performed using a working means such as a robot hand (not shown). Furthermore, the processing from step S12 onwards is performed by the automatic wiring device 30 of this embodiment.

The chuck 32, with the two guides 32a, 32b closed as a result of the processing in step S12, is moved to the position of a predetermined groove 21 among the multiple grooves 21 formed on the upper surface of the wiring jig 20 (step S13; the state shown in Figures 3 to 6). The operation of moving the chuck 32 to the position of the predetermined groove 21 is performed by a drive device (not shown) connected to the chuck unit 31.

Then, the pusher 33 arranged between the two guides 32a, 32b pushes the multiple electric wires 11 arranged in a vertical line downward (step S14; state shown in Figs. 7 to 10). The downward movement of the pusher 33 in step S14 is performed by a cylinder 34 arranged above the pusher 33, which is operated by receiving a supply of compressed air from an air pump (not shown).

When the pusher 33 moves downward and pushes the multiple electric wires 11 arranged in a vertical line downward, the elastic baffle plates 35a, 35b that close the gap on the side of the chuck 32 where the multiple electric wires 11 are pushed out are pushed aside, and the elastic baffle plates 35a, 35b are deformed, and the lowest electric wire 11 is pushed out. This action causes the single electric wire 11 to be stored in a predetermined groove 21 (step S15; see FIG. 10 in particular). In the embodiment of FIG. 10, the arrangement shape of the two guides 32a, 32b and the two elastic baffle plates 35a, 35b combined is configured to be a line-symmetric shape with the track along which the pusher 33 moves as the axis of symmetry. Therefore, even if the diameters of the multiple electric wires 11 are different, the pusher 33 can push the center of the electric wire 11 to the center of the groove 21, and therefore operates well.

At this time, all of the multiple electric wires 11 pushed downward by the pusher 33 are pushed downward, but since the groove depth of the groove 21 formed on the upper surface of the wiring jig 20 is a depth dimension corresponding to the wire diameter of the single electric wire 11 located at the bottom of the multiple electric wires 11, only one of the lowest electric wires 11 is pushed out by pushing aside the elastic baffle plates 35a, 35b, and the single electric wire 11 is stored in the specified groove 21 (step S15). At this time, the deformation of the elastic baffle plates 35a, 35b is released for the electric wires 11 other than the single electric wire 11 pushed out and stored in the groove 21, preventing them from being pushed out downward, so that the state of being lined up in a row between the two guides 32a, 32b is maintained.

After the process of step S15 is performed, the cylinder 34 is operated to return the pusher 33 to its original upper position (step S16). By performing the process of step S16, the automatic wiring device 30 according to this embodiment returns to the same state as that shown in FIG. 6. The processes from step S13 to step S16 correspond to the second step of the method of the present invention.

When the process of step S16 is completed, a control device (not shown) connected to the chuck unit 31 determines whether the number of times the electric wire 11 has been pushed out has reached a preset number of times (step S17). If the number of times the electric wire 11 has been pushed out has not reached the preset number of times (N in step S17), the chuck unit 31 is moved to a different position 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 second process (steps S13 to S16) is repeated until the number of times the electric wire 11 has been pushed out reaches the preset number of times.

When the number of times the electric wire 11 has been pushed out reaches a preset number (Y in step S17), the chuck 32 is released and the chuck unit 31 retreats to the initial position (step S18; state in Figs. 11 and 12). In this way, a series of operations for the method of the present invention for storing multiple electric wires 11 in predetermined grooves 21 is completed.

The above describes a preferred embodiment of the present invention, but the technical scope of the present invention is not limited to the scope described in the above embodiment. Various modifications and improvements can be made to the above embodiment.

For example, in the above-mentioned embodiment, as shown in FIG. 6 and FIG. 10, elastic baffle plates 35a, 35b having elasticity protruding obliquely to the direction in which the multiple electric wires 11 are pushed out (i.e., the lower side) of the two guides 32a, 32b are arranged at the respective tips. That is, one elastic baffle plate 35a, 35b is arranged for each of the two guides 32a, 32b, in total. However, for the automatic wiring apparatus according to the present invention, it is sufficient that one elastic baffle plate is arranged for at least one of the two guides. Such a modified example is shown in FIG. 14. FIG. 14 shows a specific example in which one elastic baffle plate 35a is arranged only for the first guide 32a. Even with the automatic wiring apparatus having the configuration shown in FIG. 14, it is possible to achieve the same effect as the automatic wiring apparatus 30 described above.

For example, in the above-described embodiment, the driving source for moving the pusher 33 up and down is the cylinder 34, which is operated by receiving a supply of compressed air from an air pump (not shown). However, the driving source of the pusher of the present invention may be anything that can move the pusher up and down. For example, a servo motor can be used as the driving source of the pusher 33. By using a servo motor as the driving source, the movement range of the pusher 33 can be controlled, so that the amount of movement of the electric wire 11 pushed toward the groove 21 can be controlled, and the load on the electric wire 11 placed in the groove 21 due to the pushing force can be reduced.

For example, in the above-described embodiment, it was assumed that the wiring jig 20 was fixed and the automatic wiring device 30 moved to position the wiring jig 20 relative to the groove 21. However, either the wiring jig 20 or the automatic wiring device 30 may move when positioning. In other words, the wiring jig 20 may move relative to the fixed automatic wiring device 30 to position it, or both the wiring jig 20 and the automatic wiring device 30 may move to position it.

It is clear from the claims that such modifications or improvements are also included within the technical scope of the present invention.
