Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves forcibly passing a raw metal wire through a die to impart flexibility to a drawn filament, forming a coil into a wire, and storing the filament. The present invention relates to processing equipment for linear coils that continuously processes various operations from cutting the scales to a predetermined length to taking them out.

Prior to a detailed explanation of the present invention, problems with conventional wire drawing machines will first be considered.

FIG. 1 shows an overall configuration diagram of an embodiment of the equipment of the present invention.
Since the wire drawing surface portion is almost the same as that of the conventional wire drawing machine, the conventional wire drawing machine will be explained using FIG.

In the wire drawing machine 1, the raw metal wire 1 passes through a guide roll 5, a straightening device 6, etc., passes through a die 3 fixed on a base 2, and is wound onto a wire drawing drum 4. The raw metal wire 1 is forcibly passed through the die 3 and drawn into a wire body la narrowed to a predetermined diameter.

The wire drawing operation is continued by continuously melting the raw metal wire 1, and after the wire drawing, the filament body la is cut at the welded joint or at a certain wire drawing length.
The problems with conventional wire drawing machines are as follows: It is necessary to remove the coil, and the wire drawing machine has to stop each time, making the work complicated.

(2) To remove the wire coil wound on the wire drawing drum, the wire drawing drum applies a frictional traction force sufficient to wind the wire against the resistance of the die to the wire drawing drum and the wire coil. Therefore, it is not possible to remove the striatal coil carelessly.Also, to remove the striatal coil, it is necessary to pull it out from the wire drum. Or, conversely, the drum can be pulled out from the filament coil, but in either case, it is dangerous as it involves handling a fairly heavy object.
The labor burden of the work increases. (3) Since the filament is wound onto a wire drawing drum under strong traction, the size of the filament coil is determined by the outer diameter of the drum, and in this case, strong elastic strain remains.

Therefore, due to this influence, the shape of the wire coil after being removed from the wire drawing drum becomes irregular, which increases the burden in terms of secondary processing and transportation handling. '4} Welded connection part of the striatum,
Alternatively, in order to cut the wire at a certain drawing length, it is necessary to visually detect and cut the scale part, and since the cut is at the foot of the filament where elastic strain remains strongly, it is not necessary to do it in a careless manner. It is not possible to cut the wire, and it is necessary to stop the wire drawing machine and operate the irregular cutter each time, which makes the wire cutting work complicated.

The present invention has been made in order to solve the above-mentioned problems in processing the wire coils in the conventional drawing machine, and it is possible to remove the wire coils from the wire drawing drum without stopping the wire drawing machine. The wire is drawn out, given continuous flexibility and wound on a winding drum as a wire coil of a desired size, and the wire wound on the winding drum is cut several times according to a selected signal. The purpose of the present invention is to provide processing equipment for linear coils that improves work efficiency by automating a series of operations from transferring the coils from the winding drum to a transport carrier and taking them out. .

In the above configuration, the operation of the present invention will be explained next.

In the wire drawing machine 1, the wire body la, which has been forcibly passed through the taris 3 and processed into a wire by the traction force wound around the wire drawing drum 4, is wound around the wire drawing drum 4 multiple times and its leading part is drawn. It is separated from the drum 4 and introduced into the filament bending device 7.

The three roll sets of the filament bending device 7 are driven at a circumferential speed synchronized with the wire drawing drum 4 of the wire drawing machine 1, and the pull-in roll 13 is moved toward the orientation layer roll by the action of the air cylinder 17. The bran striae la is biased between the stereotaxic layer roll 12 and
It works by squeezing the material with the appropriate pressure and pulling it under the appropriate tension.

Further, the pressing roll 14 is adjusted in advance to move toward the stereotactic eyebrow roll side by operating the handle 27, and presses the striated body la drawn therein toward the stereotactic thin roll side. Therefore, the striatum la is 3 in the periphery of each roll 12, 13, 14.
It becomes a point support, and progresses while being given flexibility to the desired curvature determined by the positional relationship of these three points, and progresses in a direction that follows the curvature of the striatum la' itself, which has been given this flexibility, and the striatum coil The wire is introduced into the wire storage device 8.

In the filament coil storage device 8, the holding arm 34 searches for a holding position where the holding arm 34 extends horizontally outward from the winding drum at the lower green portion of the winding drum 33.
By switching operation 8, the striatum bending device 7 imparts flexibility, and the rotation speed is adjusted to correspond to the curvature of the striatum a. Due to its flexibility, it is held on the holding arm 34 in a loosely wound form around the winding drum 33.

When the solenoid valve 69 of the filament coil storage device 8 is operated, the holding arm 34 swings downward from the holding position to the open position, and the filament coil lb held thereby is transferred to the winding drum 33. While rotating, it is dropped and inserted into the transport carrier 66 that has been brought downward.

After the air clutch 49 is released, the rotary operation plate 62 on the support shaft 53 of the air clutch 49 contacts the limit switch 63 during one rotation, opens the solenoid valve 64, and stops at a fixed position that does not interfere with the passage of the striated body la. do. As mentioned above, in the present invention, after the filament body wound around the wire drawing drum is separated from the wire drawing drum under a strong traction force and once stretched in a straight line,
The striatal body bending device continuously imparts a predetermined flexibility, and the direction in which this flexibility is imparted is taken in the same direction as the flexibility imparted when winding the elongated green drum. There is no increase in the stiffness of the filament body as in the case of bending, and the flexibility is imparted by the filament body passing between three roll sets constituting the filament body bending device, Since it continues to progress as it is and becomes a green striae coil, compared to a striae coil that is wound while receiving a strong traction force on the wire drawing drum of a secondary device, the tension of the striae or the temporary stop of the coil A filament coil with little elastic strain can be obtained without bending or warping of the tip of the filament.

Furthermore, the three roll sets that make up the wire bending device rotate in synchronization with the wire drawing drum, and there is no kneading phenomenon of the wire that occurs due to excessive tension or slack in the wire when passing between the rolls. The striae coils taken out to the bran striae coil storage device or transport carrier have a well-organized striatal structure as a whole, and can be handled conveniently. Next, an embodiment of the operation control of the equipment of the present invention will be described.

FIG. 9 is a block diagram of the control device.

When a weld (flaw) in the raw metal wire 1 is detected by the weld detector 67, the signal is transmitted to the arithmetic circuit 71 built in the control device 70', and the presence/absence and position of the flaw is calculated. The signal is transmitted to the arithmetic unit 72 and is also transmitted to the sampling voltage generator 73 at the same time.

At this time, the side long roller 68 is a filament! The number of pulses corresponding to the scratch position is transmitted to the arithmetic unit 72 while being in contact with a. At this time, the pulse calculator 72 determines the linear velocity v in the wire drawing drum 4 based on the number of pulses from the side rollers 68 and the sampling time Δt input from the sampling voltage generator 73.
(linear velocity of passage through the cutting blade) is calculated and outputted to the calculation circuit 74 of the solenoid valves 64 and 69, and here again the pulse calculation unit 72
When the count reaches the set value, a count up signal is output to the trout cutting command converter 76 via the scale cutting number setting converter 75, and the trout cutting command converter 76 outputs a count up signal. A command is issued, the solenoid valve 64 is operated, and the striae body la in the striae body disconnection device 9 is disconnected. At the same time, an operation command is issued to the solenoid valve 69 of the striatal coil wire storage device 8 via the timer 77 and the operation command converter 78, and the holding arm 34 is swung to the open position. release the hold on. In addition, if the number of carp cuts is set in advance in the number of uneven cuts setting converter 75, the carp cutting command will be issued n times in a row, and the sea bream cutting blade will rotate continuously n times and cut into the striatum. Since la is cut continuously n times, it is possible to cut several long pieces including the welded joint of the filament body la.

Further, the solenoid valve 69 of the striatal coil wire storage device 8 is operated again by the operation command converter 78 after Δt time set in the timer 77.
When an operation command is issued via the air cylinder 43, the holding arm 34 is returned to the holding position by actuation of the air cylinder 43. Incidentally, by opening the interlocking switch 79 connected to the timer 77, the interlocking relationship with the striatal body cutting device 9 can be released, so that the striatal The body coil lb can be freely stored or released from the stored wire state.

In addition, a manual switch 8 connected to the Nada cutting number setting converter 75
By operating 0, it is possible to cut the striatum la regardless of the detection signal of the welded portion detector 67. According to the automatic control interlocking operation described above, the welded joint of the raw metal wire is detected, the wire coil is automatically cut at the welded part by calculation based on the detection signal, and the bran from which the welded part has been removed is A strip coil can be obtained without stopping the wire drawing machine and transferred to a transport carrier for removal.

Furthermore, it is also possible to take specimens for checking the quality of the filament coil at any time during wire drawing, which is one of the effective methods of utilizing the processing equipment of the present invention.
