[Industrial applications]

 The present invention relates to a core wire arranging machine for arranging the core wires of a multi-core cable, and more particularly to a core wire supplying device of the core wire arranging machine for sending the core wires one by one to a gripping position.

[0002]

[Prior Art]

 Recently, multicore cables with connectors at both ends have been widely used as transmission lines for control signals between devices. When a connector is attached to this type of multi-core cable, first, one end side of each core wire is arranged at a predetermined position, and one end of the arranged core wire is fixed to a pin of the connector by soldering or the like.

After the connector is attached to one end side of each core wire as described above, the connector is attached to the other end side of each core wire as well. After conducting an inspection, identify the core wire, arrange this core wire at a predetermined position, and attach the connector in the same manner.

Now, FIG. 4 is a front view of a conventional core wire supplying device. In FIG. 4, reference numeral 10 denotes a core wire insertion block, and a core wire supply groove 11 that divides the block 10 into two is formed along the up-down direction in the substantial center thereof. A plurality of core wires 2 of the multi-core cable 1 (see FIG. 5) are arranged in the core wire supply groove 11 by being pushed in from below. The lowest core wire 2 is pressed upward by a push-up bar 12 extending into the core wire supply groove 11. The push-up bar 12 is fixed to one end of a vertical moving plate 13, and a plurality of support shafts 14 are inserted through the vertical moving plate 13 along the vertical direction. A rod of an air cylinder 15 is fixed to the lower surface of the vertical moving plate 13, and the air cylinder 15 presses the vertical moving plate 13 upward with a constant pressing force.

A wire delivery member 16 is movably arranged on the upper surface of the core wire insertion block 10. The wire feeding member 16 is provided with a holding groove 16a on the lower surface on the tip end side, which is aligned with the core wire supply groove 11 and into which the uppermost core wire 2 is inserted and held. The wire delivery member 16 is moved by an air cylinder 17 on the upper surface of the core wire insertion block 10. A core wire insertion groove 10a is formed on the upper surface of one end side of the core wire insertion block 10, and the position of the insertion groove 10a is set to the grip position of the core wire 2.

When the air cylinder 15 is operated in the conventional core wire supplying device having the above-mentioned structure, a pressing force is applied to the vertical moving plate 13, so that the push-up rod 12 moves the lowest core in the core wire supplying groove 11. Apply upward force to line 2. Therefore, the uppermost core wire 2 of the core wire supply groove 11 is inserted and held in the holding groove 16 a of the wire sending member 16. Next, when the air cylinder 17 is actuated, the wire sending member 16 moves to the position shown by the alternate long and short dash line on the core wire inserting block 10, so that the core wire 2 in the holding groove 16a moves to the core wire inserting block 10. It is engaged in the engagement groove 10a.

In this way, when the core wire 2 is delivered to the engagement groove 10a, the core wire is gripped by the core wire gripping portion 23 (see FIG. 5) and the continuity inspection is performed via the conductive blade. As a result, the control unit (not shown) determines the array position of the core wires 2, guides the core wire gripping unit 23 to the predetermined position of the array jig 7, and then, as shown in FIG. At 23, the core wires 2 are pushed into the arrangement groove of the arrangement jig 7 and arranged.

[0008]

[Problems to be solved by the device]

 By the way, the plurality of core wires 2 are often pushed into the core wire supply groove 11 in an intersecting state. Therefore, as shown in FIG. 4, when the wire sending member 16 moves to the grip position of the core wire 2, another core wire intersecting the core wire 2 in the holding groove 16a is pulled out from the core wire supply groove 11. However, there is a drawback that a core wire that cannot be arranged is generated. Further, as shown in FIG. 5, when the core wire 2 is gripped by the core wire gripping portion 23, and the gripping portion 23 is guided and moved, the core wire 2a intersecting the gripped core wire 2 becomes the core. It may be pulled out from the line supply groove 11 and may cover the arrangement groove of the arrangement jig 7. Therefore, when arranging another core wire 2 on the arrangement jig 7 after that, the core wire 2 cannot be pushed into the arrangement groove by the core wire gripping portion 23, and the core wire arranging machine stops due to an error and the arrangement work is performed. There was a drawback that the workability of The present invention has been made to solve such a point, and an object thereof is to provide a core wire supply device for a core wire arranging machine in which the core wire is not unnecessarily pulled out from the core wire supply groove. To do.

The guide / positioning mechanism 21 is composed of a so-called robot, and moves the arm member 22 in the lateral direction, the vertical direction, and the forward / backward direction by controlling the built-in pulse motor to position the core wire gripping portion 23.

FIG. 3 is a perspective view of the core wire gripping portion 23 from obliquely below. The core wire gripping portion 23 is a base 32 rotatably attached to the arm member 22 via a shaft 31. It has a pair of supports 33, 34 arranged on the lower surface of the base 32. One support 34 is fixed to one end of the base 32, and the other support 33 is movably engaged in a groove 32 a on the other end of the base 32. The other support 33 is moved by the cylinder 35 along the groove 32a. Clamping chucks 36 and 37 are attached to the support 34 so as to face each other. One holding chuck 36 is attached to the other holding chuck 37 so as to be close to and away from it, and is operated by an air cylinder or the like (not shown).

The support body 33 is provided with holding chucks 38, 39 for detecting continuity, respectively. The holding chuck 39 is fixedly mounted, and the other holding chuck 38 is mounted so as to be able to approach and separate from the chuck 39, and is moved by an air cylinder or the like (not shown). The conduction detecting sandwich chuck 38 is made of a conductive metal, has a conduction detecting blade 40, and is connected to a control unit such as a computer via a lead wire (not shown). In FIG. 3, a pushing member 18 is arranged on the lower surface of the base 32, and the pushing member 18 is moved downward by a cylinder 19 provided in the base 32, so that the chucks 36, 37 and 38, 39. The core wire 2 which is sandwiched and tensioned is pushed into the array groove of the array jig 7.

A core wire supply device 9 according to the present invention has a core wire insertion block 10 as shown in FIGS. 1 and 2, and a core wire that divides the block into two halves is provided substantially in the center of the block 10. The supply groove 11 is formed along the vertical direction. The other ends of the plurality of core wires 2 of the multi-core cable 1 are pushed into the core wire supply groove 11 from below and arranged in a line. The lowest core wire 2 is pressed upward by a push-up bar 12 extending in the core wire supply groove 11. As shown in FIG. 2, the push-up bar 12 is fixed to one end of a vertical moving plate 13, and a plurality of support shafts 14 are vertically inserted through the upper and lower moving plate 13. A rod of an air cylinder 15 is fixed to the lower surface of the vertical moving plate 13, and this cylinder 15 pushes the upper and lower moving plates 13 upward. A wire delivery member 16 is movably arranged on the upper surface of the core wire insertion block 10. A holding groove 16a for inserting and holding the uppermost core wire 2 is formed on the lower surface of the wire sending member 16 on the tip side. The holding groove 16a is formed in such a size that only one core wire 2 is inserted and held. The wire delivery member 16 is moved by the cylinder 17 on the upper surface of the core wire insertion block 10. A core wire insertion groove 10a having a substantially semicircular cross section is formed on the upper surface of one end side of the core wire insertion block 10.

In the vicinity of the core wire supply groove 11, a pair of holding plates 24 and 25 are arranged so as to face each other. An elastic holding plate 26 made of an elastic material such as rubber is fixed to the opposing surfaces of the sandwiching plates 24 and 25. One end face of one holding plate 24 is fixed to the core wire insertion block 10 along the core wire supply groove 11. The other holding plate 25 is supported by a rod 27a of an air cylinder 27. The air cylinder 27 is fixedly supported by the core wire insertion block 10 and the like by an appropriate means to move the holding plate 25 toward and away from the holding plate 24. That is, the air cylinder 27 is controlled while the uppermost cord 2 is arranged as will be described later, and the holding plate 25 is brought closer to the holding plate 24, so that a plurality of other cords in the cord feeding groove 11 are moved. The core wire 2 is held by a pair of holding plates 24 and 25.

Next, the operation of the core wire supply device 9 of the present invention will be described together with the operation of the core wire arranging machine. First, the cylinder 5 is operated and the other end of the multi-core cable 1 is clamped by the clamping blocks 4a and 4b. Then, the other end of the core wire 2 is pushed in a line into the core wire supply groove 11 provided in the core wire insertion block 10 of the core wire supply device 9, and the air cylinder 15 is operated to push up the vertical moving plate 13. The uppermost cord 2 is pushed into the holding groove 16a of the wire feeding member 16 and held. After that, the air cylinder 27 is operated to bring the holding plate 25 close to the holding plate 24, thereby holding the other plurality of core wires 2 between the holding plates 24 and 25.

Next, the cylinder 17 is operated to move the wire delivery member 16 on the upper surface of the core wire insertion block 10. As a result, the uppermost core wire 2 in the holding groove 16a is engaged with the core wire engaging groove 10a. In this case, since the sandwiched core wire 2 is sandwiched between the sandwiching plates 24 and 25 even if it intersects with the uppermost core wire 2, it is not pulled out from the core wire supply groove 11. On the other hand, in this state, the pulse motor of the guide / positioning mechanism 21 is operated, and the core wire gripping portion 23 is positioned at a predetermined gripping position of the core wire via the arm member 22.

When the core wire gripping portion 23 is positioned in this way, as shown in FIG. 3, the sandwich chuck 36 is moved by an air cylinder (not shown) or the like, so that the core wire 2 is sandwiched between both. It is sandwiched by the holding chucks 36 and 37. At the same time, the holding chuck 38 for detecting continuity also moves, so that the other portion of the core wire 2 is held by the holding chucks 38, 39. Further, since the holding chuck 38 for detecting continuity has the continuity detecting blade 40, the continuity detecting blade 40 breaks the coating layer of the core wire 2 and comes into contact with the conductor. Therefore, the core wire 2 is conducted, and the conduction detection signal is supplied to the control unit (not shown).

The control section determines which of the pins of the connector 3 is conductive by the conduction detection signal. That is, for example, when the third pin is conductive, it is determined to be the third pin, and the array position of the array jig 7 is calculated. Since the guide / positioning mechanism 21 is controlled by the result of this calculation, the core wire gripping portion 23 is moved to a predetermined arrangement position of the arrangement jig 7 via the arm member 22.

Since the cylinder 35 of the core wire gripping portion 23 is operated at this moving position, the support body 33 moves in the arrow A direction. Therefore, tension is applied to the core wire 2. In this state, the cylinder 19 is actuated and the pushing member 18 moves downward, so that the core wire 2 is pushed into the arrangement groove of the arrangement jig 7 at a predetermined arrangement position.

By the way, since the core wire 2 in the core wire supply groove 11 is clamped by the pair of clamping plates 24 and 25 even while the core wire gripping portion 23 is moving, the core wire gripping portion Even if the core wire 2 gripped by 23 intersects with another sandwiched core wire, the crossed core wire is not similarly pulled out from the core wire supply groove 11. Therefore, since the crossing cord 2 does not cover the arrangement jig 7, the subsequent arrangement work of the cords 2 can be performed without any trouble. When the arrangement of the uppermost cord 2 is completed, the holding plate 25 is separated from the holding plate 24 by the operation of the air cylinder 27, so that the holding of the cord 2 in the cord supply groove 11 is released.
