DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device for winding a wire, which is spirally wound in a horizontal direction from a final winding coiler in a drawing process, into a coil shape, and stacking it on a lower wire loading receiving frame.

[0002]

2. Description of the Related Art A drawn wire W is spirally fed horizontally from a coiler, and slides on the outer periphery of a curved guide 1 as shown in FIG. It is changed and falls on the wire loading receiving frame 2,
One coil is continuously stacked. Then, the coil-shaped wire W is stored in the receiving frame 2 by a set weight or a set length, and the receiving frame 2 is provided as a supply wire for the next process.

Further, as shown in FIG. 12, the receiving frame 2 is slightly inclined, and the wires W are continuously stacked while the receiving frame 2 is gradually rotated by the motor M. As a result, the wire rods W are uniformly spread and stacked around the receiving frame 2, so that the loading amount of the receiving frame 2 can be increased.

[0004]

However, when the wires W are piled up on the receiving frame 2, the wires W continuously fall from above, so that the wires W are not properly stacked in the vertical direction and are displaced. Stacked in the state. For this reason, there is a case where the upper and lower sides are interchanged, although they are corrected by hand. Then, the portion is entangled, which may cause disconnection when the wire is taken out when used as a supply wire in the next process. If the wire breaks, the operation must be stopped and work such as welding and connecting the wire rods must be performed, so that the operation rate of the device is greatly reduced.

[0005] As shown in Fig. 13, there is a method in which a wire W is stored at the distal end side of a guide 1 projecting in a horizontal direction with respect to a coiler, and when a certain amount of the wire W is stored, the wire W is manually piled up on a receiving frame 2. . In this method, when used as a supply wire in the next step, the wire can be taken out without being entangled, but it is inefficient because it requires human labor and is not suitable for continuous operation by automation.

[0006] In view of the above, an object of the present invention is to provide a winding device that automatically forms a coil without tangling a wire.

[0007]

As shown in FIGS. 1 and 2, a means for solving the problem according to the present invention is a curve for guiding a wire W spirally fed out of a coiler 3 in a horizontal direction and being pushed out in a state of being in close contact.

9, a wire rod amount detecting means for detecting the stored dose of the wire rod W, and moving the wire receiving lever 4 by a fixed amount each time the wire rod W is stored by a set amount so that the wire rod W is kept in close contact with the wire rod. And when the stored dose is full,
Activate the stopper 8 and then replace the first stopper 8 with the
Control means for operating the second stopper 9 . The wire receiving lever 4 is located outside the guide 1.
Each of the flat plates 41 has four flat plates 41 arranged on all sides.
The receiving frame 2 can pass through the middle space formed by
The flat plate 41 moves the receiving frame 2 with respect to the guide 1.
It is a guide for positioning.

[0008]

In the above-mentioned means for solving the above problems, when the wire W is fed out from the coiler 3 to the guide 1, the wire W spirals and slides on the outer periphery of the guide 1 and is pushed in close contact with the previous wire W. Are stacked in a state where the wire receiving lever 4 is jammed. When the wire is stored by the set amount, the wire receiving lever 4 is lowered along the rail 5 by a fixed amount. As the wire receiving lever 4 descends on the guide 1, the wire W also slides down and is stored in a clogged state.

When the stored dose at the wire receiving lever 4 becomes full, the wire receiving lever 4 is lowered to the lower limit position. At this time, in order to continuously operate the coiler 3 even during the replacement work of the receiving frame 2, first, the first stopper 8 is lowered to temporarily block the wire W fed from the coiler 3 , and
Up the first stopper 8 and lower the second stopper 9
The wire W so that the wire W is more dammed
The guide 1 is moved on the outer circumference. The wire receiving lever 4 is opened by the opening means 7, and the stored wire W moves to the receiving frame 2 in a clogged state. Then, the receiving frame 2 on which the wires W are stacked is replaced with an empty receiving frame 2 . At this time,
The receiving frame 2 is formed by the flat plate 41 of the wire receiving lever 4.
Guided and guided by passing through the middle space
It is positioned with respect to the guide 1. Thereafter , the wire receiving lever 4 is raised and closed so as to store the wire W, and the second wire receiving lever 4 is closed .
The stopper 9 is moved up, and the wire W which has been dammed is stored in the wire receiving lever 4.

As described above, the wire W is stored in a state in which the wire W is jammed by the wire receiving lever 4, and the wire does not fall apart into the receiving frame as in the related art. Then, even if the wires are transferred to the receiving frame 2, they are stacked as they are, so that the wires do not cross vertically and do not become tangled.

The operating pressure of the opening / closing cylinder 60 is maintained at such a pressure that the wire receiving lever 4 does not open due to the weight of the stored wire W.

The stoppers 8 and 9 are disposed above the guide 1 and include a first stopper 8 near the coiler 3 and a second stopper 9 far from the coiler 3. The guide 1 is moved up and down so as to freely enter and exit the gap. The cylinder 62 is attached to a horizontal frame 63 fixed to the upper part of the coiler 3.

As shown in FIG. 6, a plurality of position detectors comprising proximity switches for detecting the positions of the wire receiving lever 4 and the receiving table 16 are arranged on the frame 40. An upper limit detector 65 corresponding to the upper limit position A of the wire receiving lever 4 in order from the top, an exchange position detector 66 corresponding to the position B of the wire receiving lever 4 when the receiving frame is replaced, and a lower limit position C of the wire receiving lever 4.

In addition, in FIG. 6, F is a guide position which is the position of the wire receiving lever 4 when the receiving frame 2 is raised, and at this time, plays a role of a guide for positioning the receiving frame 2 below the guide 1.

A wire rod amount detecting means for detecting the stored dose of the wire rod W at the wire receiving lever 4 is provided.
Is obtained from the number of rotations of the rotary shaft 13, and the number of rotations is detected by a counter.

The control means includes a moving means 6, an opening means 7, first and second stoppers 8, 9 and a turntable 1 in a predetermined sequence in accordance with signals from the detector and the counter.

The function of lowering the wire receiving lever 4 by a fixed amount each time the wire is stored by a set amount, and the first and second functions when the stored dose is full. It has a function of temporarily stopping the wire W by operating the two stoppers 8 and 9 and a function of exchanging the receiving frame 2 by moving up and down the receiving table 16 and rotating the turntable 15. Note that the set amount of the wire storage is set so that the wire W does not bite into the input portion of the block 11. Also,
The certain amount of lowering the wire receiving lever 4 is such that there is no gap between adjacent wires on the guide 1.

In the above configuration, as shown in FIG. 6, when the wire W is fed out from the coiler 3 to the stationary guide 1, the wire W becomes spiral and slides on the outer periphery of the guide 1 to move forward. The wire is pushed out in close contact with the wire W, and is stacked in a state of being tightly packed in the wire receiving lever 4. And
Set amount (600 m when the wire diameter is 0.8 mm in this embodiment)
When only the number of wires is stored, the drive motor 53 is driven for a predetermined time (0.8 seconds in this embodiment) to lower the traveling body 43 along the rail 5 by a fixed amount. As the wire receiving lever 4 descends on the guide 1, the wire W is also stored while keeping the wire rod S slid and clogged.

The operation of lowering and stopping the wire receiving lever 4 is performed when the stored dose is full (in this embodiment, 835 when the wire diameter is 0.8 mm).
00m). When the vehicle is full, the driving motor 53 is driven as shown in FIG.
3 is lowered along the rail 5 and the wire receiving lever 4 is
When the lower-limit position detector 67 detects that the lower-limit position C, which is approximately halfway between the two, has been reached, the drive motor 53 is stopped. At this time, the first stopper 8 is lowered to temporarily dam the wire W fed from the coiler 3.
Due to the lowering of the wire receiving lever 4, the supply of the wire W from the coiler 3 cannot catch up, and the wire W is
Since the wire W is pulled apart and is in a separated state, the wire W
They do not overlap even if they are dammed.

When the wire receiving lever 4 reaches the lower limit position C, the flat plate 41 is rotated downward by the operation of the opening / closing cylinder 60 to be opened, and the stored wire W is moved to the receiving frame 2 while being stuck. To go. Then, as shown in FIG. 8, the wire receiving lever 4 is located at the exchange position B above the lower end of the guide 1.
And lower the cradle 16 to the lowering position E,
The work for replacing the receiving frame 2 is started. While this operation is being performed, when 10 seconds elapse after the lowering of the first stopper 8, the first stopper 8 is raised and the second stopper 9 is lowered. This is because since the coiler 3 is operating continuously, the wire W blocked by the first stopper 8 accumulates, and the wire W bites into the wire entry portion of the block 11. 9 moves the wire W so that the wire W is more dammed. Therefore, the work of replacing the receiving frame 2 can be performed without stopping the operation.
Continuous operation is possible, and the operation rate is improved.

In the replacement work, first, the cylinder 26 of the wire transfer lever 24 is extended, and the wire transfer lever 24 is lowered to be in a standby posture. Then, after unlocking the lock of the turntable 15, the turntable 15 is turned clockwise to detect the position of the turntable 15, and when the empty receiving frame 2 approaches below the guide 1, the rotation is reduced. When the receiving frame 2 comes directly below the guide 1, the turntable 15 is stopped and locked.

Next, as shown in FIG.
Is operated for a predetermined time, the wire receiving lever 4 is lowered to the guide position F below the guide 1, and the opening / closing cylinder 60 is operated to bring the flat plate 41 into a closed position in which the flat plate 41 is in a horizontal state. Then, the pedestal 16 is raised to the raised position D. At this time, the receiving frame 2 is guided by passing through the middle space formed by the flat plate 41 of the wire receiving lever 4 while making contact with the flat plate 41, and the cover attached to the lower end of the guide 1. 12 is properly connected. When the replacement of the receiving frame 2 is completed, the opening / closing cylinder 60 is operated to bring the wire receiving lever 4 into the open position again, and is raised without contacting the guide 1.

When the wire receiving lever 4 reaches the upper limit position A,
As shown in FIG. 10, the lifting is stopped and the wire receiving lever 4 is stopped.
To the closed position. Then, the second stopper 9 is raised,
The blocked wire W slides, is received by the wire receiving lever 4, and is stored. Thereafter, the above operation is repeated. Further, the wire passing lever 24 is rotated to be in a horizontal state, and the hanging wire W is lifted. Thereby, when the wire rod W is moved to the receiving frame 2 with the wire receiving lever 4 in the open position at the lower limit position, there is enough room for the wire rod W to move even if the wire rod W is pulled.
Disconnection can be prevented, and the wire W can be prevented from interfering with other operations. When the wire W is cut, the wire W is easily cut.

As described above, the wires W are stored in a state where the wires W are jammed by the wire receiving lever 4, and are stacked as they are even if they are transferred to the receiving frame 2, so that the wires W may intersect vertically. Disappears. Therefore, even when the coiled wire W stacked on the receiving frame 2 is used as a supply wire, the wire W is sequentially taken out from the upper side.
Therefore, the work at the time of disconnection becomes unnecessary, and the operation rate of the entire machine can be improved.

Further, the coiled wire rods W stacked on the receiving frame 2 are not eccentric stitches one by one, but in a small bundle state in which a certain amount of the wire rods W overlap, and are slightly eccentrically shifted. It is in a state of being stacked. Since such a state is very stable, even if an impact is applied to the receiving frame 2, the coil-shaped wire W does not collapse. Moreover, since the coil can be formed in a state where the wire W is clogged, the gap between the wire and the wire becomes small, and the volume occupied by the wire W with respect to the loading amount of the receiving frame 2 increases, so that a large amount of wire can be handled at once. This leads to an improvement in work efficiency, such as a reduction in operation time and convenience for the subsequent process.

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that many modifications and changes can be made to the above-described embodiment within the scope of the present invention.

In this embodiment, the wire receiving lever 4 is intermittently lowered in accordance with the length of the wire. However, the wire receiving lever 4 is provided with a pressure sensor or a weight sensor so that the weight of the stored wire can be reduced. The lowering of the wire receiving lever 4 is controlled in accordance with the condition, or the wire W on the guide 1 is controlled by an optical sensor or a camera.
May be detected and the lowering of the wire receiving lever 4 may be controlled. Further, the wire receiving lever 4 may be continuously lowered in accordance with the amount of the wire W fed from the coiler 3. As a result, the wire W can always be in a clogged state on the guide 1.

Further, since the wire W slides on the outer periphery of the guide 1 while its movement is regulated by the wire receiving lever 4, the wire W not only bends downward but also in other directions except upward such as sideways. The wire can be kept in a clogged state even when it is turned. For this reason, versatility as a coil-shaped wire winding device is enhanced.

As a means for moving the wire receiving lever, the wire receiving lever may be rotated by a worm reducer and a motor or a rack and pinion and a cylinder in a region along the curve of the guide, and may be moved up and down by a cylinder in a linear region.

[0036]

As it is clear from the description above, according to the present invention, according to the present invention, dense fed horizontally spirally from the coiler
On a curved guide that guides the wire that is extruded while wearing , along the rail that matches the curvature of the guide
The wire rod is moved while being stored in a dense state by the wire receiving lever that moves and is guided to the receiving frame, so the wire is stored in a tightly packed state without being entangled, and even if it is transferred to the receiving frame, it is not changed. Can be stacked in a state. Therefore, the wires do not cross up and down, and even when the coiled wires stacked in the receiving frame are sequentially taken out from the upper side when used as a supply wire in the next process, the wires do not become tangled and do not break. . Thereby, the work at the time of disconnection becomes unnecessary, and the operation rate of the entire machine can be improved.

Further, the coil-shaped wire rods stacked on the receiving frame are in a small bundle state in which a certain amount of wire rods are overlapped, and are staggered and shifted little by little, so that they are very stable. Therefore, even if an impact is applied to the receiving frame, the coiled wire does not collapse. In addition, since the coil can be formed in a state where the wire is packed, the gap between the wires becomes small, the volume occupied by the wire with respect to the loading capacity of the receiving frame becomes large, and a large amount of wire can be handled at one time. In addition, insert the wire into the curved guide guide.
The guide can be held down
May be set horizontally or horizontally, so that the versatility as a winding device can be enhanced.

Further, by providing the first and second stoppers which operate in order, the wire fed from the coiler can be used.
It is more dammed without getting stuck in the coiler, the work of replacing the receiving frame can be performed without stopping the operation of the coiler, and the continuous operation can be automated, thereby improving the working efficiency. In addition, the receiving frame is
By guiding with a plate, it is possible to
The receiving frame can be positioned properly.
