Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention allows a long wire wound around a spool to be paid out in predetermined lengths, cut into a predetermined length, and then used to manufacture tubes. This invention relates to a tube wire supply device that is supplied to the head of a machine.

[Conventional technology]

In a tube manufacturing machine, a rotary table equipped with multiple heads is rotated intermittently, and each head position performs a specific task, but during this process, the tube is cut to a specific length. There is a step in which the wire is supplied and, for example, welded.

Conventionally, a wire feeding machine has been placed near a predetermined head position of the rotary table having a plurality of heads.

This wire feeding machine includes a wire drawing chuck that pulls out a long wire wound around a spool in predetermined lengths, a stop chuck that clamps the drawn wire, and a cutter that cuts the wire supported by the stop chuck. The long wire wound around the spool is cut to a predetermined length and sent out.

A wire of a predetermined length fed out from such a wire feeding machine was supplied to the head of the rotary table at a predetermined position.

[Problem that the invention seeks to solve]

However, in the conventional method, a predetermined length of wire sent out from a wire feeding machine was directly fed to the head of the rotary table, which caused the following problems.

That is, when the head of the rotary table rotates to a predetermined position, the wire feeding machine draws out a long wire wound around a spool by a predetermined length using a drawer chuck, supports this with a stop chuck, Since the wire is then cut with a cutter and fed to the head of the rotary table, a considerably long waiting time is required from the time the head of the rotary table stops at a predetermined position until the wire is fed. Ta.

Moreover, the wires supplied to the head of the rotary table are subjected to welding, sealing, and other operations at this head, and this operation requires a certain amount of time.

As a result, the intermittent rotation speed of the rotary table is limited by the sum of the waiting time for the wire to be supplied from the wire supply machine and the time for welding and sealing the supplied wire within the head, It was not possible to increase the intermittent rotation speed of the rotary table.

However, recent tube manufacturing machines tend to increase the intermittent rotation speed of the rotary table to improve manufacturing efficiency, and in other processes, efforts are being made to improve the working speed on each head.

However, since the wire supply process takes time, it has been an obstacle to increasing the manufacturing speed.

The present invention was developed based on the above-mentioned circumstances, and aims to provide a tube wire feeding device that can increase the intermittent rotation speed of the rotary table of a tube manufacturing machine and improve manufacturing efficiency. be.

[Means for solving problems]

The present invention provides a wire conveying device adjacent to a rotary table of a tube manufacturing machine, which is moved intermittently in synchronization with the intermittent rotation of the rotary table, and is equipped with a plurality of turrets. A wire supply machine is disposed near the turret to feed out a long wire wound around a spool in predetermined lengths, cut it into a predetermined length, and supply the wire to a predetermined length. A length of wire is transferred to a turret of the wire conveying device, and the movement of the wire conveying device supplies the wire held on the turret to a head at a predetermined position in the tube manufacturing machine. .

[Effect]

According to the above configuration, a predetermined length of wire supplied from the wire supply machine is once held by the turret of the wire conveying device, and the wire held by the turret is transferred to the head at a predetermined position in the tube manufacturing machine. Since the tube-making machine head only needs to receive the wire already cut to length from the turret of the wire transport device, the waiting time for the wire to be fed from the wire-feeding machine is reduced. no longer needed.
While the head of the tube manufacturing machine is doing work such as welding and sealing, the wire feeding machine is
The wire wound on the spool can be cut to a predetermined length and fed to other turrets of the wire conveying device.In other words, the wire wound on the spool can be cut to a predetermined length and fed to other turrets of the wire conveying device. Because the work of cutting the wire to the specified length can be done in parallel,
The intermittent rotation speed of the rotary table of the tube manufacturing machine can be increased, in other words, the intermittent stop time can be shortened, and manufacturing efficiency can be improved.

Each turret 6 is equipped with a chuck mechanism (not shown) that holds a pair of anode wires w, w.

Wire feeding machines 7, 7 are arranged at positions D and E of the wire conveying device 4, respectively. These wire supply machines 7, 7 cut a long wire wound around a spool into a predetermined length and deliver it to the turret 6 of the wire conveying device 4.

The structure of one wire feeding machine 7 is shown in FIGS. 2 to 4, and will be described.

In the figure, 10 is a base, on which the support column 11 and the wire conveying device 4 are placed.

First, second, and third support plates 12, 13, and 14 are attached to the column 11 so as to extend in the horizontal direction, and a bracket 15 is fixed to the first support plate 12. There is. A spool 16 wound with a long wire w' is rotatably supported on the bracket 15.

Further, a wire strainer 17 is fixed to the first support plate 12, and this wire strainer 1
7 has a plurality of rollers 18...

A plurality of guide posts 19 are spanned from the first support plate 12 to the third support plate 14, and these guide posts 19 are connected to the first support plate 12 and the second support plate 14. A long wire is located between the support plates 13 and wound around the spool 16.
A wire drawing chuck 20 is provided for drawing out w' in predetermined lengths.

A stop chuck 21 is provided below the wire pull-out chuck 20 and on the second support plate 13 to clamp the drawn-out wire.

A cutter 22 for cutting the wire w' supported by the stop chuck 21 is provided below the second support plate 13.

Furthermore, the guide posts 19... are located between the second support plate 13 and the third support plate 14,
An elevating nozzle 23 is provided that supplies the wire w cut into a predetermined length by the cutter 22 to the turret 6 of the wire conveying device 4.

As shown in FIG. 3, the wire drawer chuck 20 has a frame 30, which is supported by the guide post 19- so that it can be raised and lowered. Driven. Incidentally, the elevating rod 31 is moved up and down by the action of a cam (not shown). A fixed chuck 32 is attached to the frame 30, and a movable chuck 34 is guided by guide rails 33, 33.
is attached so as to be slidable in the direction of arrow G. This movable chuck 34 is moved by the arrow G by a spring 35.
It is designed to be attracted in the opposite direction and has an abutment block 36. A roller 37 is in contact with the side surface of this contact block 36, and this roller 37 is pivotally supported by a rotating lever 38. The base end of the rotating lever 38 is connected to the first support plate 1
The tip of the rotating lever 38 is connected to a wire drawer chuck opening/closing cylinder 39 fixed to the second support plate 13.

When the wire drawer chuck opening/closing cylinder 39 is extended, the rotating lever 38 is rotated and the roller 37 pushes the pressing block 36 in the direction of arrow G. As a result, the movable chuck 34 is moved in the direction of arrow G, and the wire is connected between it and the fixed chuck 32.
It is designed to hold w′.

This clamping action is performed when the frame body 30 is raised by the lifting rod 31, so that the wire drawer chuck 20 clamps the wire w' that has passed through the wire strainer 17 in the raised position. In this clamped state, the lifting rod 31 is lowered and the frame 30 is pulled down. The wire w' is let out from the spool 16 in accordance with the amount of pull. And the wire w′ is wire strainer 1
7, it passes between rollers 18, and the winding curl when being wound around the spool 16 is corrected.

The amount by which the wire drawer chuck 20 is pulled down is 1
Determine the length of the book anode wire w. That is, when the wire drawer chuck 20 is pulled down, the wire drawer chuck opening/closing cylinder 39 is contracted, and the movable chuck 34 is moved in the direction opposite to the direction of arrow G under the force of the spring 35. Therefore, the movable chuck 34 is similar to the fixed chuck 32.
Since it separates from the wire, release the wire w' that has been pulled down.

Then, with the movable chuck 34 separated from the fixed chuck 32, the frame 30 is raised by the lifting rod 31. Then, in the raised position, wire w' is clamped as described above.

Therefore, the amount of wire w' to be drawn out is determined by the vertical stroke of the wire drawing chuck 20.

The stop jack 21 is connected to the second support plate 1.
3, and a movable chuck 42 attached to a cylinder 41 for opening and closing the stop chuck.

This stop chuck 21 holds the wire w' drawn out by the wire drawing chuck 20, and when the frame 30 is pulled down, the stop chuck opening/closing cylinder 41 is extended.
A wire w' is held between a movable chuck 42 and a fixed chuck 40.

After this clamping is performed, the wire drawing chuck 20 releases the wire w' and moves upward.

As shown in FIG. 4, the cutter 22 is
It is constructed by attaching a fixed blade 51 and a movable blade 52 to a holder 50. The movable blade 52 is connected to a rod 53, a link lever 54, and a rod 55 shown in FIG. 2, and is advanced toward the fixed blade 51 when the rod 55 is raised.

When the stop chuck 21 clamps the wire w', the rod 55 is raised and the movable blade 52 advances toward the fixed blade 51, so that the wire w' is cut between the movable blade 52 and the fixed blade 51.
The anode wire w cut into a predetermined length by this cutting is dropped into the guide nozzle 56.

The anode wire w of a predetermined length dropped into the guide nozzle 56 is dropped into the elevating nozzle 23.

The elevating nozzle 23 is attached to an elevating block 60, and the elevating block 60 is guided in the vertical direction by guide posts 19. A rod 61 is connected to the lifting block 60, and as the rod 61 moves up and down, the lifting nozzle 23 is raised and lowered.

This elevating nozzle 23 is raised when the rotary table 5 of the wire conveying device 4 is intermittently rotated, so that it can escape so as not to get in the way when the turret 6 moves to the position directly below. When the rotary table 5 stops intermittently and the turret 6 moves to a position directly below it, it is lowered and approaches a wire chuck mechanism (not shown) on one side of the turret 6. Then, when the anode wire w cut by the cutter 22 is dropped into the guide nozzle 56,
The anode wire w is reliably supplied to the turret 6 by the elevating nozzle 23 which falls from the guide nozzle 56 and approaches the turret 6.

The wire feeding machines 7 having such a structure and function are installed one each at position D and position E in FIG.
Two anode wires are supplied to the same turret 6, one each.

The operation of the apparatus of the embodiment having the above configuration will be explained.

The rotary table 2 of the mount manufacturing machine 1 is the first
When the head 3 holding the mount m comes to the B position by being intermittently rotated in the direction of the arrow A in the figure, the rotary table 5 of the wire conveying device 4 is also intermittently rotated in the direction of the arrow C and one of the turrets 6 also returns to the B position. It will be moved to.

At position B, a pair of anode wires w, w held by a chuck mechanism (not shown) of the turret 6 are welded to lead wires l, l of the mount m, as shown in FIG. When this welding is finished, the turret 6 releases the pair of anode wires w, and the mount manufacturing machine 1
The head 3 moves in the direction of arrow A and moves on to the next work step.

When the above one turret 6 is in position B, D
The other turrets 6 located at positions E and E are supplied with anode wire w from wire supply machines 7, 7, respectively. That is, the wire supply machine 7 at position D supplies the anode wire w on the right side in FIG. 5 to the turret 6, and the wire supply machine 7 at position E supplies the anode wire w on the left side in FIG. 5 to the turret 6. A wire w is supplied. Therefore, the two anode wires w and w are supplied to the turret 6 until the rotary table 5 of the wire conveying device 4 rotates once in the direction of the arrow C and the turret 6 reaches the position B. .

As a result, the time that the head 3 of the mount manufacturing machine 1 is stopped at position B is only the time required to weld the anode wires w, w to the lead wires l, l, and therefore the mount manufacturing machine 1
Manufacturing efficiency can be increased by increasing the intermittent rotation speed.

That is, the long wire wound around the spool 16 is fed out to a predetermined length, cut and supplied at positions D and E during the welding time.
Therefore, while the head 3 of the mount manufacturing machine 1 is stopped at the B position, the long length wound on the spool 16 can be It is no longer necessary to add time to pay out a predetermined length of wire, cut it, and supply the wire, and the time required to pay out a predetermined length of the long wire wound around the spool 16, cut it, and supply the wire is eliminated. This makes it possible to shorten the stoppage time of the head 3.

In the above embodiment, an apparatus for welding the anode wires w, w to the lead wires l, l of the mount m was described, but the present invention is not limited to this, and for example, the device may be used to weld the anode wires w, w to the lead wires l, l of the mount m. It is possible to supply the tube wire by sealing the tube.

Furthermore, although the wire conveying device is constructed by having a plurality of turrets attached to a table that rotates intermittently, it may also be constructed by having turrets attached to a conveyor that runs endlessly.

[Example of idea]

As explained above, according to the present invention, a wire of a predetermined length supplied from a wire supply machine is once held by a turret of a wire conveying device, and the wire held by the turret is transferred to the tube manufacturing machine. Since the head of the tube making machine only needs to receive the wire already cut to length from the turret of the wire conveying device, the wire is fed from the wire feeding machine. This eliminates the need for waiting time. While the head of the tube manufacturing machine is performing welding, sealing, etc., the wire feeding machine cuts the wire wound around the spool to a predetermined length and transfers it to the other turrets of the wire conveying device. In other words, while welding and sealing at the head, cutting the wire wound around the spool to a predetermined length can be done at the same time, making it possible to cut the wire wound around the spool to a predetermined length. The intermittent rotation speed of the rotary table can be increased, in other words, the intermittent stop time can be shortened, and manufacturing efficiency can be improved.
