Description

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 rod, which is wound out in a spiral shape in the horizontal direction from a coiler for final winding in a drawing process, into a coil and stacking the wire rod on a lower frame for receiving the wire rod.

[0002]

2. Description of the Related Art A wire rod W that has been subjected to a drawing process is spirally fed out horizontally from a coiler, and slides on the outer circumference of a curved guide guide 1 as shown in FIG. It was changed and dropped on the wire rod 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 is supplied as a supply wire rod for the next process together with the receiving frame 2.

Further, as shown in FIG. 12, the receiving frame 2 is slightly tilted, and the wire W is continuously stacked while the receiving frame 2 is rotated little by little by the motor M. As a result, the wire rods W are evenly spread and piled up around the receiving frame 2, and the loading amount of the receiving frame 2 can be increased.

[0004]

However, in both of them, when the wire rods W are stacked on the receiving frame 2, the wire rods W continuously fall from above and fall apart from each other without properly stacking them in the vertical direction. Pile up in a pile. Therefore, it may be corrected by hand, but the upper and lower sides may be interchanged and may remain intersecting. Then, that portion becomes entangled, which causes a disconnection when the wire rod is taken out when it is used as a supply wire rod in the next step. If the wire breaks, the operation must be stopped, and the work such as welding and connecting the wire rods must be performed, resulting in a significant decrease in the operating rate of the device.

Further, as shown in FIG. 13, there is a method in which the wire W is stored on the leading end side of the guide 1 which is provided so as to project in the horizontal direction with respect to the coiler, and when the wire W is stored to some extent, it is stacked on the receiving frame 2 by hand. . In this method, the wire can be taken out without being tangled when it is used as a supply wire in the next step, but it is inefficient because it requires manpower and is not suitable for continuous operation by automation.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a winding device for automatically coiling a wire rod without entanglement.

[0007]

As shown in FIGS. 1 and 2, a means for solving the problems according to the present invention includes a curved guide guide 1 for guiding a wire W, which is helically fed in a horizontal direction from a coiler 3, in a downward direction. , A wire rod receiving frame 2 for stacking the wire rods W guided by the guide guide 1 in a coil shape, an openable / closable wire receiving lever 4 for storing the wire rod W on the outer periphery of the guide guide 1, and the guide guide 1. Rails 5 according to the bending of the rails, moving means 6 for moving the wire-receiving levers 4 along the rails 5, and opening means for opening the wire-receiving levers 4 to send the stored wire W to the receiving frame 2. 7, stoppers 8 and 9 for damming the wire W on the guide 1 upstream of the wire receiving lever 4, wire amount detection means for detecting the stored amount of the wire W, and the wire W being stored in close contact with each other. It's the amount set to line A control means for a predetermined amount of movement of Sen受 lever 4 each time it is 貯線 is one provided.

[0008]

In the above means for solving the problem, when the wire W is fed from the coiler 3 to the guide 1, the wire W becomes spiral and slides on the outer periphery of the guide 1 and is pushed in close contact with the previous wire W. , The wire receiving levers 4 are piled up in a clogged state. When the set amount is stored, the wire receiving lever 4 is moved down along the rail 5 by a certain amount. As the wire receiving lever 4 descends on the guide 1, the wire W also slides down and is stored in a jammed state.

When the stored dose at the line receiving lever 4 becomes full, the line 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, the stoppers 8 and 9 may be lowered to temporarily stop the wire W fed from the coiler 3. The wire receiving lever 4 is opened by the opening means 7, and the stored wire rod W moves to the receiving frame 2 in a jammed state. Then, when the receiving frame 2 in which the wire rods W are stacked is replaced with an empty receiving frame 2, the wire receiving lever 4 is raised and closed so that the wire rod W can be stored, and the stoppers 8 and 9 are raised and dammed. The wire W that has been used is stored in the wire receiving lever 4.

In this way, the wire rod W is stored in a state where the wire rod W is clogged by the wire receiving lever 4, and the wire rod does not fall apart into the receiving frame unlike the conventional case. Then, even if the wire rods are transferred to the receiving frame 2, they are stacked in the same state, so that the wire rods do not vertically intersect with each other, and the entangled state does not occur.

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

The stoppers 8 and 9 are arranged above the guide 1 and comprise a first stopper 8 close to the coiler 3 and a second stopper 9 far from the coiler 3, each of which is rod-shaped and guided by a cylinder 62. It can be moved up and down freely in and out of the gap of the guide 1. The cylinder 62 is attached to a horizontal frame 63 fixed to the upper portion of the coiler 3.

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, it serves as a guide for positioning the receiving frame 2 below the guide 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.
The length of the wire W fed from the wire rod is obtained from the number of rotations of the rotating shaft 13, and the number of rotations is detected by a counter.

The control means has a moving means 6, an opening means 7, first and second stoppers 8 and 9, and a turntable 1 in a predetermined sequence according to signals from the detectors and counters.

The set amount of the storage line is set so that the wire W does not get caught in the line-in portion of the block 11. Also,
The fixed amount by which the wire receiving lever 4 is lowered is such that no gap can be formed between the adjacent wire rods on the guide 1.

In the above structure, as shown in FIG. 6, when the wire W is fed from the coiler 3 to the stationary guide guide 1, the wire W spirals and slides on the outer periphery of the guide 1. The wire rod W is pushed out in close contact with the wire rod W, and is stacked in a state that the wire receiving lever 4 is closely packed. And
Set amount (600 m when the wire diameter is 0.8 mm in this embodiment)
When the electric power is stored only for a while, the drive motor 53 is driven for a predetermined time (0.8 seconds in this embodiment) to lower the traveling body 43 by a certain amount along the rail 5. As the wire receiving lever 4 descends on the guide 1, the wire W also slides down and is stored in a jammed state.

The operation of lowering and stopping the wire receiving lever 4 is full (according to the present embodiment, 835 when the wire diameter is 0.8 mm).
00m) is repeated. When it is full, as shown in FIG. 7, the drive motor 53 is driven to drive the traveling body 4
3 along the rail 5 and the wire receiving lever 4 receives the receiving frame 2
When the lower limit position detector 67 detects that the lower limit position C, which is approximately in the middle of, is reached, the drive motor 53 is stopped. At this time, the first stopper 8 is lowered to temporarily stop the wire W fed from the coiler 3.
Due to the lowering of the wire receiving lever 4, the supply of the wire material W from the coiler 3 cannot catch up, and the wire material W on the upstream side of the guide 1 is
Since it is pulled and is in a separated state, the wire W
Even if they are stopped, they do not overlap.

When the open / close cylinder 60 is actuated, the flat plate 41 of the wire receiving lever 4 which has reached the lower limit position C is rotated downward to be released, and the wire W stored therein moves to the receiving frame 2 in a clogged state. 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.
Up to the lower position E,
The replacement work of the receiving frame 2 starts. While this work is being performed, the first stopper 8 is raised and the second stopper 9 is lowered 10 seconds after the first stopper 8 is lowered. This is because the coiler 3 is continuously operating, and therefore the wire W blocked by the first stopper 8 accumulates and the wire W is bitten into the wire entry portion of the block 11, but the second stopper W is used to prevent this. The wire W is moved so that more of the wire W can be dammed by means of 9. Therefore, since the replacement work of the receiving frame 2 can be performed without stopping the operation,
It enables continuous operation and improves the operating rate.

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 a standby position. Then, after unlocking the turntable 15, the turntable 15 is turned clockwise, the position of the turntable 15 is detected, and the rotation is decelerated when the empty receiving frame 2 approaches below the guide guide 1. The turntable 15 is stopped and locked when the receiving frame 2 comes directly under the guide guide 1.

Next, as shown in FIG. 9, the drive motor 53
Is operated for a predetermined time to lower the wire receiving lever 4 to a guide position F below the guide guide 1, and the opening / closing cylinder 60 is operated to bring the flat plate 41 into a horizontal posture. 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 contacting the flat plate 41, and is properly connected to the cover 12 attached to the lower end of the guide guide 1. It When the replacement of the receiving frame 2 is completed, the opening / closing cylinder 60 is operated to return the wire receiving lever 4 to the open posture, and the wire receiving lever 4 is raised without coming into contact with the guide guide 1.

When the wire receiving lever 4 reaches the upper limit position A,
As shown in FIG. 10, the rise is stopped and the wire receiving lever 4
To a 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. After that, the above operation is repeated. Further, the wire passing lever 24 is turned to be in a horizontal state, and the hanging wire W is lifted up. 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 a margin to move even if the wire rod W is pulled,
It is possible to prevent the wire from breaking, and to prevent the wire W from interfering with other work. When the wire W is cut, the wire W is easily cut.

In this way, the wire rods W are stored in a state of being jammed by the wire receiving levers 4, and even if the wire rods W are transferred to the receiving frame 2, they are stacked as they are, so that the wire rods W may vertically intersect. Disappear. Therefore, when the coil-shaped wire rods W stacked on the receiving frame 2 are used as the supply wire rods, even if they are sequentially taken out from the upper side, they are stacked in order and do not become entangled, and there is no disconnection.
Therefore, the work at the time of disconnection becomes unnecessary, and the operating rate of the entire machine can be improved.

Further, the coil-shaped wire rods W stacked on the receiving frame 2 do not form a knitted shape in which each wire rod is eccentric, but become a small bundle in which the wire rods W are overlapped to some extent, and are slightly eccentric and displaced. It is in a stacked state. Since such a state is very stable, even if an impact is applied to the receiving frame 2, the coiled wire W does not collapse. Moreover, since the coil can be formed in a state where the wire rods W are clogged, the gap between the wire rods becomes small, and the volume occupied by the wire rods W with respect to the loading amount of the receiving frame 2 becomes large, so that a large amount of wire rods can be handled at one time. This leads to improvement of work efficiency such as reduction of operating time and improvement of convenience for the subsequent process.

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

In the present embodiment, the wire receiving lever 4 is intermittently lowered according to the length of the wire rod. However, the wire receiving lever 4 is provided with a pressure sensor or a weight sensor so that the weight of the stored wire rod is reduced. The lowering of the wire receiving lever 4 is controlled according to the above, or the wire W on the guide 1 is controlled by an optical sensor or a camera.
The lowering of the wire receiving lever 4 may be controlled by detecting the degree of clogging. Further, the wire receiving lever 4 may be continuously lowered in accordance with the amount of the wire W delivered from the coiler 3. As a result, the wire W can be always stuck on the guide 1.

Since the wire W slides on the outer periphery of the guide 1 while the movement of the wire receiving lever 4 is restricted by the wire receiving lever 4, the guide W can be bent not only downward but also in any direction such as sideways or upward. The wire can be kept in a clogged state. Therefore, versatility as a coiled wire winding device is enhanced.

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

[0036]

As is apparent from the above description, according to the present invention, the wire rod is kept in a dense state by the wire receiving lever on the curved guide guide for guiding the wire rod which is helically fed in the horizontal direction from the coiler. Since the wires are moved while being stored and guided to the receiving frame, the wires are stored in a clogged state without being entangled and can be stacked in the same state even if they are transferred to the receiving frame. Therefore, the wires do not cross each other up and down, and when the coiled wire stacked on the receiving frame is used as the supply wire for the next process, even if the wires are taken out from the upper side in sequence, the wire does not become entangled and does not break. . This eliminates the need for wire breakage work and improves the operating rate of the entire machine.

Further, the coil-shaped wire rods stacked on the receiving frame are in a small bundle state in which the wire rods are overlapped to some extent, and are slightly eccentrically shifted and stacked, so that they are very stable. Therefore, the coiled wire does not collapse even if an impact is applied to the receiving frame. Moreover, since the coil can be formed in a state where the wire rods are clogged, the gap between the wire rods becomes small, the volume occupied by the wire rods becomes large with respect to the loading amount of the receiving frame, and a large amount of wire rods can be handled at one time.

Moreover, by providing the stopper for damming the wire rod, the receiving frame can be replaced without stopping the operation of the coiler, and the continuous operation can be automated and the working efficiency can be improved.
