2. Description of the Related Art A wire harness is an electric wiring system including a large number of electric wires, terminals, connectors, and the like incorporated in a car, a copying machine, and the like. The method includes a stripping step of peeling off the covering of the portion, a terminal crimping step of crimping a terminal fitting to an end of the stripped electric wire, a terminal inserting step of inserting the terminal into the connector housing, and a binding step of binding the electric wire.

[0003] Conventionally, these manufacturing processes have been manually performed, but recently, mechanical devices for automating each process have been proposed. In the manufacture of a wire harness using a mechanical device, handling of electric wires is an issue. Conventional 1
One method has been to transport the wire cut and clamped with a wire clamp rod (for example, Japanese Patent Publication No.
No. 66790).

[0004] As another method, there has been a method in which electric wires are laid on a wiring board and a wire harness is formed on the wiring board (see, for example, Japanese Patent Application No. 1-130422). In the former method of handling electric wires, the electric wire clamp rod 3
The end of the wire is gripped, and the wire is transported in a hanging state, making it difficult to handle when the wire length is long,
Care must be taken to ensure that the wires do not get tangled during transport.

[0005] On the other hand, the latter method is excellent in that the work is performed in a state where the electric wires are laid on the wiring board, so that the wiring board may be transported at the time of work, and the work is easy to perform.

[0006]

By the way, in designing the automatic production line of the wire harness using the wiring plate, which is the latter method, how to incorporate the wiring plate feeder into the manufacturing line is described.

The wired wiring board is conveyed from the work station A1 to the next work station A2 by the wiring board feeding device B1. Then, at the work station A2, a stripping step of stripping the covering of the wired wire end is performed while the wiring board is being conveyed by a pitch feeder (not shown) provided in the station. When the peeling is completed at the work station A2, the wiring board is sent from the work station A2 to the next work station A3 by the wiring board feeding device B2. Then, at the work station A3, the terminal fitting is crimped to the core wire at the end of the stripped electric wire. At the time of terminal crimping, the wiring board is pitch-fed by a pitch feeding device (not shown) provided in the work station A3.

[0008] Because of such a configuration, conventionally, a wiring board feeder for transporting the wiring board from one work station to another work station is required, and the production line becomes longer, larger and more complicated. There was a problem of doing.
The present invention has been made in order to solve such a disadvantage of the prior art.

[0017]

An embodiment of the present invention will be described below in detail with reference to the drawings. 1, three modules 20A which have wiring board feeding apparatus according to an embodiment provided in the present invention, 20B, 20C are flat, substantially view schematically showing the connection in series. Each module 20A,
Reference numerals 20B and 20C denote process automation modules in which predetermined manufacturing processes of the wire harness are automated.

Each of the modules 20A, 20B, and 20C has, as a common configuration, a base frame 21A, 21B, and 21C as a working base and a transport device 22A, 22B, and 22C as a wiring board feeding device. (Hereinafter, when collectively referring to the module, the base frame, and the transporting device, the numerals 20, 21,
Letters A, B, and C attached after 22 are omitted). In FIG. 3, each module 20A,
The processing mechanism for each process provided in 20B and 20C is not shown.

One of the features of this common configuration is that the transfer device 22 provided on the base frame 21 is formed with a protruding portion 23 which protrudes from the base frame 21 by a predetermined length L0. . In this embodiment, the protruding portion 23 can enter a module, for example, on the upstream side of the production line. In this way, when the wiring board is conveyed from the upstream module, for example, the module 20A to the module 20B connected downstream thereof, there is an advantage that the delivery of the wiring board can be performed smoothly. There is also an advantage that a separate transport device does not have to be inserted between the modules 20A and 20B.

Note that the protruding portion 23 may not enter the upstream module but may enter the downstream module. Another feature of the common configuration described above is that between modules that are connected to each other, for example, between modules 20A, 20B, and 20C.
The arrangement positions of the transfer devices 22A, 22B, and 20C are, for example, the left half side in the width direction of the base frame 21A, the right half side in the width direction of the base frame 21B, and the left side in the width direction of the base frame 21C. That is, they are alternately arranged on the opposite side in the width direction, such as the half side. With such an arrangement structure, even if each protruding portion 23 enters the module 20 on the upstream side, it can be prevented from hitting the transport device 22 provided in the module 20 and the predetermined length L0 Since the protruding portion 23 partially opposes the transfer device 22 of the upstream module 20 in parallel, it is possible to transfer the wiring board from the transfer device 22A of the upstream module, for example, the module 20A to the transfer device 22B of the downstream module 20B. It becomes.

The lengths L1, L2, L3 of the base frame 21 in each module 20 may be different for each module or may be equal. Also, the width of the base frame 21 in each module 20 may be different for each module or may be common. Next, a common configuration of each module 20 will be described by taking a specific configuration example.

FIG. 2 is a plan view showing a specific example of the common configuration of the module, FIG. 3 is a front view thereof, and FIG. 4 is a right side view thereof. Referring to FIGS. 2 to 4, the module 20 includes a lower base frame 21 having a rectangular parallelepiped outer shape.
a and an upper base frame 21b mounted on the lower base frame 21a, and four casters 2 with stoppers are provided below the lower base frame 21a.
4 is attached. Therefore, the lower base frame 21a and the upper base frame 21b can be easily moved and easily arranged at a desired position, and can be immobilized at the arranged positions.

The transfer device 22 includes a lower base frame 21a.
It has a longitudinal mounting member 25 secured thereon. A first pulley 26 is provided at the right end of the mounting member 25, and a second pulley 27 is provided at the left end of the mounting member 25. A transport timing belt 28 is provided between the first pulley 26 and the second pulley 27. Is spanned. A timing pulley 33 attached via a bearing mechanism 32 is connected to the first pulley 26. Also, the lower base frame 21a
The servo motor 3 which is the driving source of the transfer device 22
4 is attached. A drive pulley 36 is attached to the rotation shaft 35 of the servo motor 34, and a timing belt 37 extends between the drive pulley 36 and the above-described timing pulley 33. Accordingly, the rotational force of the servo motor 34 is transmitted to the timing pulley 33 via the driving pulley 36 and the timing belt 37, and the rotation of the timing pulley 33 is transmitted to the first pulley 26 via the bearing mechanism 32, and the first pulley 26 The conveyance timing belt 28 is driven by the rotation of.

The transport timing belt 28 has a connecting member 2
The moving member 30 is attached via the connecting member 9. The moving member 30 is guided by a guide rail 31 provided in an upper portion of the mounting member 25 and extending in parallel with the transport belt 28, and is movable in the left-right direction in FIG. 4 or FIG. Therefore, when the transport timing belt 28 is driven, the transport timing belt 28 causes the moving member 30 connected to the transport timing belt 28 and the connecting member 29 to move in the left-right direction.

The moving member 30 is a member having a predetermined length in the moving direction.
Two pin units 38a and 38b are attached. The pin units 38a and 38b respectively have positioning pins 39a and 39a which are moved up and down by a hydraulic cylinder, for example.
39b is provided. The interval between the two positioning pins 39a and 39b is, for example, 505 mm. Each of the positioning pins 39a and 39b can be engaged with a feed hole formed in the wiring board by being raised.

As described above, by using the two positioning pins 39 and keeping the two positioning pins 39 at a predetermined interval, the wiring board is accurately positioned at the time of feeding the wiring board so that the wiring board is not rattled. There is an advantage that it can be transported. That is, if there is only one positioning pin 39, the wiring board may rattle in the direction intersecting with the transport direction during transport. However, as in this embodiment, the two positioning pins 39a,
If the positioning pins 39a and 39b are provided and the positioning pins 39a and 39b are spaced apart from each other by a predetermined distance, the two positioning pins 39a and 39b
The wiring board is reliably positioned by 39b, and is conveyed without rattling.

As a modification, the positioning pins 39
May be set to three or more, and the wiring board may be positioned and transported with more pins. Also,
If the transport device is provided with a transport guide that prevents the wiring board from rattling in the direction intersecting the transport direction during transport,
It is also possible to use only one positioning pin 39.

The feature of the module 20 is that the left end (the left end in FIG. 2 or 3) of the transfer device 22 is a protruding portion 23 which protrudes leftward from the base frames 21a and 21b. This protruding part 23
The protruding dimension is set to L0 (for example, L0 is a dimension obtained by adding a predetermined margin α to the interval 505 mm between the two positioning pins 39a and 39b, that is, L0 = 505 mm + α), and the moving member 30 extends to the leftmost side. In the moved state, the right positioning pin 39 of the two positioning pins 39a and 39b attached to the moving member 30 is moved.
b is configured to protrude from the guide frames 21a and 21b.

The protruding portion 23 is a module 2

The module 20 further includes a proximity sensor 41 for detecting a wiring board on the upper base frame 21b.
A wiring plate stopping cylinder 42 provided near the proximity sensor 41 is provided. In FIG. 2 or FIG.
When the wiring board is conveyed from the left side, the tip of the conveyed wiring board is detected by the proximity sensor 41. The detection output of the proximity sensor 41 is a cylinder control device (not shown)
And the cylinder 42 is raised in response to the detection output. Then, the leading end of the fed wiring board collides with the raised cylinder 42 and is stopped.

A feed hole is formed on the back surface of the wiring board stopped as described above at a position facing the positioning pins 39a and 39b. Therefore, the positioning pins 39a,
When 39b is raised, it is inserted into the feed hole of the wiring board.
Then, thereafter, the cylinder 42 is lowered. In the upper left part of FIG. 3, the first stop position of the wiring board 9 is indicated by a two-dot chain line. The wiring board 9 in a state where the positioning pins 39a and 39b are inserted into the feed holes of the wiring board 9 and are conveyed to the right end is indicated by a two-dot chain line in the upper right part.

In this state, the protruding portion 23B of the transfer device (not shown) of the next module connected to the right side of the module 20 has entered the module 20 as shown by the dashed line in FIG. From this, the wiring board 9 is transferred to the transport device (extending portion 23B) of the next module, and transported to the next module. In addition, in FIG. 2 or FIG. 4, reference numeral 43 indicates rollers that hold both sides of the wiring board when the wiring board is transported.

In FIG. 2 or FIG. 4, reference numeral 44 indicates a processing mechanism mount. For example, when the module 20 is assembled as a peeling module, the peeling processing mechanism is attached to the processing mechanism mounting base 44. The arrangement position of the mount 44 is, for example, the position shown in FIG. 2 by way of example, and the mount is made larger or the position is changed according to the type of processing mechanism to be mounted.

FIG. 5 is an illustrative view for explaining feed holes formed in the wiring board 9 used in the wire harness production line to which the module 20 is connected. As shown in FIG. 5, at least two pairs of feed holes 45 and 46 are formed on the lower surface of the wiring board 9. One set of feed holes 45 is provided in a direction (width direction) crossing the conveying direction of the wiring board 9, for example, on the left side, and the other set of feed holes 46 is provided on the right side. Then, any of the holes 45 (4
6) also includes two holes 45a, 45b (46a, 46b), and the holes 45a, 45b (46a, 46b).
The interval b) is a predetermined dimension, for example, 505 mm, which is equal to the interval between the positioning pins 39a and 39b in this embodiment.

Of the two sets of feed holes, one set of feed holes 4
Reference numeral 5 is for inserting and transporting positioning pins in the preceding module. The other set of feed holes 46 is for inserting positioning pins in the next module. FIG. 6 is a diagram illustrating a modified example of the feed holes of the wiring board 9. Feeding holes 45, 46 in wiring board
May be formed around the center of the wiring board 9 as shown in FIG. Further, as shown in FIG. 6B, for example, six feed holes 45a, 45b, 45c, 4
6a, 46b and 46c are formed, of which A
The wiring board 9 may be transported using two sets of feed holes 1 and A2 or two sets of feed holes B1 and B2.

The specific configuration of each module 20 described with reference to FIGS. 2 to 4 is merely an example, and various modifications are possible. For example, the module 20 includes a lower base frame 21a and an upper base frame 2
1b, but such a base frame 21
Instead of a and 21b, a base table or the like may be used. The point is that the work base may be used, and its shape and structure can be variously changed according to the purpose.

Further, the configuration of the transport device 22 is not limited to the configuration of the embodiment, and various changes can be made based on the contents described in the claims.
