- The present invention relates to an electric wire supplying apparatus for supplying an electric wire from a nozzle to a working machine at the time of working of electric wire.
- 2. Description of the Related Art
- For example, there is an electric wire working apparatus for conducting a peeling step for peeling a coating skin of a contact of a tip end of a long electric wire (electric cable) used for a wire harness (electric wire for automobile), a contact crimping step for connecting the peeled contact to another contact by crimping, a cutting step for cutting the electric wire into a predetermined length, a peeling step for peeling the coating skin of the other contact of the cut electric wire, and a contact crimping step for connecting the peeled other contact to another contact by crimping. In such an electric wire working apparatus, an electric wire supplying apparatus for supplying a tip end of the long electric wire by a predetermined length to a working machine that conducts the peeling step whenever each working is completed.
- The present assignee previously proposed an electric wire supplying apparatus (see Japanese Patent Application No. H10-297291) (not prior art) as shown in FIGS. 1 and 2. In FIGS. 1 and 2, a driving
cylinder 3 is fixed to a tip end of aturning arm 1 through a connectingplate 2, and afixing holder 4 is fixed to the drivingcylinder 3. Thefixing holder 4 comprises aholder body 5 having arecess 5 a, and alid 7 fixed to an upper portion of theholder body 5 throughbolts 6 for covering an upper portion of therecess 5 a. Atip end 9 of an electricwire transfer tube 8 and abase end 11 of anozzle 10 are disposed in therecess 5 a. Thetip end 9 of the electricwire transfer tube 8 and thebase end 11 of thenozzle 10 are pressed by thelid 7 and fixed. - As shown in FIG. 2, an electric wire W is transferred toward the
nozzle 10 through an electricwire insertion passage 8 a in the electricwire transfer tube 8, and the transferred electric wire is led out from a tip end opening 10 b of thenozzle 10 through anelectric wire passage 10 a in thenozzle 10. Thetip end 9 of the electricwire transfer tube 8 is provided with anotch 9 a that is opened downward, and theholder body 5 is provided at its portion corresponding to thenotch 9 a with an opening 5 b. An electricwire pressing portion 13 fixed to apiston rod 12 of the drivingcylinder 3 is disposed in the opening 5 b. The electricwire pressing portion 13 is driven by the drivingcylinder 3 and moved into and out from thenotch 9 a, and the electricwire pressing portion 13 can move between a pressing position where the electricwire pressing portion 13 presses the electric wire W of the electricwire insertion passage 8 a and a standby position where the electric wire W of the electricwire insertion passage 8 a is allowed to be transferred. - In the above structure, if the electric wire W inserted into the electric
wire insertion passage 8 a of the electricwire transfer tube 8 is moved in an electric wire sending-out direction, a tip end of the electric wire W is guided by the electricwire insertion passage 8 a and transferred toward thenozzle 10. When the tip end of the electric wire W comes out from the electricwire transfer tube 8, the tip end enters into theelectric wire passage 10 a of thenozzle 10, and the tip end in the electricwire transfer tube 8 is guided therein and led out from the tip end opening 10 b. When the tip end is led out from the tip end opening 10 b by a predetermined length, the sending-out operation is stopped, thereby bringing the electric wire W into a state in which the electric wire W is to be pulled out by a predetermined length by thenozzle 10. Various working machines are disposed at predetermined rotation positions where theturning arm 1 is turned and at positions in the vicinity of and opposed to thenozzle 10, and the tip end of the electric wire W led out from the tip end of thenozzle 10 is worked by the various working machines. When the tip end is worked, the electricwire pressing portion 13 is moved to the pressing position to clamp the electric wire W, and when a predetermined working is completed, the tip end of the electric wire W is cut into a predetermined length. This cut tip end portion of the electric wire W is sent to a subsequent step, the electricwire pressing portion 13 is moved to the standby position to release the clamping motion, the tip end of the electric wire W of the electricwire transfer tube 8 is sent through a predetermined length, the electric wire W is pulled out through a predetermined length from thenozzle 10, and the above operations are repeated. That is, the electric wire supplying apparatus supplies a tip end of the long electric wire W from the tip end of thenozzle 10 sequentially whenever a predetermined working of the tip end of the electric wire W is completed. - When various electric wires are replaced due to color change of the electric wire W or when electric wire W run out and is re-supplied, it is necessary to send a new electric wire W from the base end of the electric
wire transfer tube 8 to thenozzle 10. - However, in the conventional electric wire supplying apparatus, since the tip end portion of the electric
wire transfer tube 8 is provided with thenotch 9 a and the opening 5 b opened therein, if the tip end portion of the electric wire W is bent or suspended down, the tip end abuts against an inner surface of the opening 5 b of thefixing holder 4 as shown in FIG. 2, and there is an adverse possibility that the electric wire W can not reliably be sent toward thenozzle 10. - The present invention has been accomplished to solve the above problems, and it is an object of the invention to provide an electric wire supplying apparatus capable of reliably sending a new electric wire from an electric wire transfer tube toward a nozzle.

The electricwire pressing portion 31 is air-driven by theair cylinder 22 and is moved into and out from thenotch 28 a. The electricwire pressing portion 31 can move between a pressing position where the electricwire pressing portion 31 presses the electric wire W and a standby position where the electric wire W of the electricwire insertion passage 27 a is allowed to be sent out. That is, theair cylinder 22 and the electricwire pressing portion 31 constitute electricwire pressing means 29. - A
nozzle 32 is disposed on the side of the tip end of the electricwire transfer tube 27, and includes ablock base end 33 and aflexible tube 34 fixed to a tip end of theblock base end 33, and anelectric wire passage 32 a is formed in theflexible tube 34. A tip end of theflexible tube 34 of theelectric wire passage 32 a is a tip end opening 32 b, and the electric wire W is led outside from the tip end opening 32 b. Thenozzle 32 is provided at its portion closer to the electricwire transfer tube 27 with a projectingportion 35. The projectingportion 35 has a semi-cylindrical shape which completely complements and coincides with a shape of thenotch 28 a when the projectingportion 35 is butted to the tip end of the electricwire transfer tube 27. That is, thetip end 28 and the projectingportion 35 butted thereto form a pipe. - The projecting
portion 35 and theblock base end 33 are detachably fixed to anozzle support holder 36. One ends of a pair of left andright connection rods nozzle support holder 36. This pair ofconnection rods tube fixing holder 23. Thenozzle 32 is supported by the transfertube fixing holder 23 through thenozzle support holder 36 and theconnection rods connection rods tube fixing holder 23. If theconnection rods nozzle 32 can move between a close position (position shown in FIG. 4) where the projectingportion 35 is brought into close contact with thenotch 28 a of the electricwire transfer tube 27 and butted to thenotch 28 a to close theopening 24 b, and an open position (position shown in FIG. 5) where the projectingportion 35 is separated from thenotch 28 a of the electricwire transfer tube 27 to open theopening 24 b. - The other ends of the pair of
connection rods vertical rod 39. Thevertical rod 39 is connected, through aconnection portion 40, to apiston rod 42 of a nozzle-movingair cylinder 41 that is nozzle driving means. That is, thenozzle 32 moves between the close position and the open position by a driving force of the nozzle-movingair cylinder 41. - Next, the operation of the above structure will be explained. When a new electric wire W is allowed to pass to the
nozzle 32 for changing quality, size or color of the electric wire W, as shown in FIG. 8A, thenozzle 32 is brought into the close position, and the electric wire W inserted into the electricwire transfer tube 27 is transferred into the electric wire sending-out direction. If the tip end of the electric wire W reached thenotch 28 a of the electricwire transfer tube 27, since thenotch 28 a butts to the projectingportion 35 of thenozzle 32 and theopening 24 b of the transfertube fixing holder 23 is closed, the electric wire W is guided to theelectric wire passage 32 a of thenozzle 32 even if a tip end of the electric wire W is bent or suspended downward. The transferred electric wire W is led out from the tip end opening 32 b of thenozzle 32 through theelectric wire passage 32 a in thenozzle 32 as shown with a phantom line in FIG. 8A. Therefore, the new electric wire W can reliably be sent from the electricwire transfer tube 27 toward thenozzle 32. - After the inserting operation of the new electric wire W is completed, as shown in FIG. 8B, the
nozzle 32 is moved to the open position so that the electricwire pressing portion 31 can retreat into thenotch 28 a, and the electricwire pressing portion 31 can freely clamp the electric wire W and release the clamp. Working of the contact will be explained concretely. In each of predetermined rotation positions where the turningarm 20 is turned, various working machines are disposed in positions in the vicinity of and opposed to thenozzle 32, and a tip end of the electric wire W led out from the tip end of thenozzle 32 is worked by the various working machines. When the tip end is worked, the electricwire pressing portion 31 is moved to the pressing position to clamp the electric wire W, and if a predetermined working is completed, the tip end portion of the electric wire W is cut into a predetermined length. This cut tip end portion of the electric wire W is sent to a subsequent step, the electricwire pressing portion 31 is moved to the standby position to release the clamping state, the tip end portion of the electric wire W of the electricwire transfer tube 27 is sent out through a predetermined length, the electric wire W is let out through a predetermined length, and the above operations are repeated. That is, the electric wire supplying apparatus A supplies a tip end of the long electric wire W from the tip end of thenozzle 32 sequentially whenever a predetermined working of the tip end of the electric wire W is completed. - In this embodiment, since the
nozzle 32 can be moved between the close position and the open position by the driving force of the nozzle-movingair cylinder 41, it is possible to automatically move thenozzle 32, and to automatically send the electric wire W. - In this embodiment, the
nozzle 32 is supported by theconnection rods tube fixing holder 23 and thenozzle support holder 36 fixed to theconnection rods tube fixing holder 23 through theconnection rods nozzle support holder 36 in such a manner that thenozzle 32 is movable. Therefore, it is possible to stably position thenozzle 32 with respect to the electricwire transfer tube 27 and to stably move thenozzle 32. - In this embodiment, when the projecting
portion 35 has the shape which completely complements and coincides with the shape of thenotch 28 a when the projectingportion 35 is butted to the tip end of the electricwire transfer tube 27. Therefore, the tip end of the new electric wire W smoothly passes through the connected portion between the electricwire transfer tube 27 and thenozzle 32 and thus, it is possible to more reliably send the new electric wire from the electricwire transfer tube 27 toward thenozzle 32. - According to the embodiment, the projecting
portion 35 has the shape which completely complements and coincides with the shape of thenotch 28 a of the electricwire transfer tube 27, but the projectingportion 35 may have a shape closing theopening 24 b in the close position and having no recess that gets in the way of moving the electric wire W through the connected portion between the electricwire insertion passage 27 a and theelectric wire passage 32 a, e.g., a shape substantially complementing thenotch 28 a of the electricwire transfer tube 27. Further, thenozzle 32 is supported by the transfertube fixing holder 23 through theconnection rods nozzle support holder 36, but thenozzle 32 may be movable without being supported by the transfertube fixing holder 23. Further, although the nozzle driving means comprises the nozzle-movingair cylinder 41, the nozzle driving means may be of another structure only if it generates a driving force for moving theconnection rods
