Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire winding device for winding a wire that has been heat treated, mainly in a wire heat treatment line or the like.

Generally, rolled wire rods are wound onto a winder with a certain weight (maximum of about 3 tons) and handled as one coil. In many cases, the material is defective, and of course it is necessary to discard it before shipping. In addition, when wire rods are not heat-treated directly on the production line but are heat-treated on another line, in order to make the heat treatment easier to handle, weld the end of one coil and the start of the next coil in advance. However, such a welded connection part also needs to be removed as a defective heat treatment part. Furthermore, when the heat-treated wire corresponding to one coil has been wound on the winder, the heat treatment line is temporarily stopped, the wires are bundled, and the setup is changed to remove them from the winder. The parts of the wire that were staying inside the heat treatment furnace and the parts that were located outside the heat treatment furnace but were indirectly affected by the heat also had abnormal heat treatment conditions due to the stoppage, and were unable to start the next winding. It is necessary to remove this.

In the case of the last example above, methods have been proposed for removing the coil from the winder without stopping the heat treatment line, but this requires high equipment costs and a large amount of space.

For this reason, in a conventional wire rod winding device, for example, in a wire rod heat treatment facility, the turntable T, welding machine WE, heat treatment furnace F, feed The device R and the flying shear S are arranged in this order, and on the downstream side of the flying shear S, a sorter D and a winder WI, which constitute a wire winding device, are arranged. The turntable T is used to set the coil C to be heat-treated, and has a vertical axis Ts at the center of rotation on which the coil C should be set, and the welding machine W is used to set the coil C to be heat-treated. A heat treatment furnace F is used to heat-treat the coil C and the start end of the next coil in sequence, and is comprised of an induction coil, other combustion furnaces, etc. Feeding device R
is a pair of upper and lower drive rolls with the rotation axis horizontal
The flying shear S is equipped with a pair of upper and lower rotary blades Su and Sd, and the flying shear S is configured to feed the wire L pulled out from the coil C to the downstream side. Wire L
It is configured to cut without stopping the The sorter D has a guide groove Dt which is bifurcated into a good product guide part Dg and a defective product guide part Db and has a Y-shape in plan view on the downstream side, and a branch part between the good product guide part Dg and the defective product guide part Db. It is composed of a distribution plate Dp that selectively closes both guide parts Dg and Db, and by operating the distribution part Dp with an air cylinder Dc, etc., the non-defective parts of the wire L are separated. Good products are distributed to the Dg side, and defective products are distributed to the Db side of the defective product guide. Further, the winding material WI is arranged facing the downstream end of the good product guide portion Dg of the guide groove Dt in the sorter D,
It is configured to automatically chuck the end of the wire guided through the good guide part Dg and wind it up at the same feed speed without stopping the wire.

The coil C to be heat treated is set on the axis Ts of the turntable T, and the starting end Li of the wire L drawn out from it is placed in the heat treatment furnace F, between the driving rolls Ru and Rd of the feeding device R, and the flying shear S. Pass it sequentially between the upper and lower rotary blades Su and Sd so that it faces the inlet side of the guide groove Dt of the sorter D. Then, the heat treatment furnace F is operated, but since it takes some time for the heat in the heat treatment furnace F to reach a stable state, wait until the heat in the heat treatment furnace F becomes stable, and move the drive roll Ru of the feeding device R. This will activate Rd. By the way, of the wire L pulled out from the coil C, the part from the starting end Li to the exit side of the heat treatment furnace F is a part that has not been heat treated, and the part located inside the heat treatment furnace F, above it, and downstream. Until the heat in the heat treatment furnace F stabilizes, a small part on the side is affected by heat that is different from the normal heat treatment conditions.In the end, the part from Li to Lo of the wire L is a defective part and cannot be heat treated. The part upstream of the Lo position on the upstream side of the furnace F is the part that should be a non-defective part. This Lo position can be predicted once the layout of the various equipment mentioned above that makes up the heat treatment equipment is decided, and therefore the Lo position can also be predicted.
The length of the wire L from the position to the starting end Li of the wire L is also determined, and the Lo position in the heat treatment line is determined by the feeding device R.
This can be detected by counting the number of pulses emitted from a pulse generator (not shown) connected to either axis of the drive rolls Ru, Rd.

As mentioned above, the guide groove Dt in the initial sorter D
Since the incoming wire L is a defective part, the sorting plate Dp is initially set to the position where the good part guide part Dg side is closed, and in this state, the heat treatment furnace F is stabilized and at the same time the feeding device R is driven. Activate rolls Ru and Rd. The starting end Li of the wire L is the guide groove Dt, the distribution plate Dp
is guided to the defective product guide section Db side.
The Lo position of the wire L passes through the heat treatment furnace F and the feeding device R to the upper and lower cutter Su of the flying shear S,
When it reaches between Sd, the upper and lower cutters Su and Sd are rotated to cut the wire L at the Lo position. The defective part of the cut wire L is sent to a stock part (not shown) via the defective guide part Db, and the subsequent good part of the wire L from position Lo onwards is also sent to the guide groove Dt.
I am guided by Therefore, the end of the defective part is placed on the sorting plate.
The moment it passes through Dp, operate the sorting plate Dp to close the defective product guide section Db. As a result, the starting end of the non-defective part is guided to the non-defective guide part Dg side, reaches the winder WI, is automatically chucked, and is wound up by the winder WI.

When the front end position of the defective part at the end of the coil C, that is, the end of the wire L, reaches the flying shear S, the rotating blades Su, Sd of the flying shear S
is activated to cut the wire L, and at the same time, the feeding device R is stopped, and the remaining end of the wire L and the starting end of the coil C newly inserted into the turntable T are welded using a welding machine WE.

On the other hand, the wire L wound up by the winding machine WI is bundled, the diameter of the winding portion is reduced, the wire rod L is removed from the bundle, and the wire rod L is sent as a single coil to a shipping process. The winding section expands the diameter and resets it in preparation for the next winding.
When such a setup change is completed, the feeding device R is operated again, but during this setup change, the part of the wire L that has remained in the heat treatment furnace F and the part that has been indirectly affected by heat due to this parts, welding machine
The connecting part between the wire L and the next wire welded by WE, or the terminal end of the wire L and the starting end of the next wire are defective parts, and such defective parts are first placed in the guide groove Dt. Since it will be introduced, the distribution board Dp
is set to the position where the good product guide part Dg is closed. The feeding device R is operated to guide the defective part to the defective part guide part Db side, and when the number of pulses emitted by the pulse generator detects that the end of the defective part in the next wire has reached the flying shear S,
The flying shear S is operated to cut the wire, and at the same time the cut defective part finishes passing through the defective product guide part Db, the distribution plate Dp is switched to close the defective product guide part Db. As a result, only the good part of the new wire rod is guided to the winder WI via the good guide part Dg, and is wound there.

The above-described operations are successively repeated to heat-treat the wire L. By the way, in the case of the conventional winding device as mentioned above, it is necessary to prepare two individual winding machines, and there are disadvantages in that each winding machine must be operated individually when changing setups, etc. The defective parts were short in size and had defects such as requiring a lot of work.

The present invention has been made in view of the above circumstances, and its purpose is to provide a winding section for good wire rods and a winding section for defective wire rods that are arranged concentrically in parallel in the axial length direction of the rotation center shaft. , a means for reducing the diameter of the wire wound on the non-defective winding section in order to remove it, and a means for separating the wire rod wound on the defective winding section from the non-defective winding section in order to remove it, and a means for reducing the diameter of the wire wound on the defective winding section, and means for reducing the diameter of the defective product winding section in conjunction with the diameter reduction operation of the non-defective product section; and a traverser having a guide roller that is moved to an area facing each of these parts in order to selectively wind the wire according to the good part and the defective part, and cut the wire into the good part and the defective part. It is possible to wind the product into each winding section without any trouble, and it is extremely easy to dispose of defective parts.
An object of the present invention is to provide a wire winding machine that can greatly improve the efficiency of handling work for defective parts.

When the number of pulses emitted by the pulse generator PG reaches a predetermined number, in other words, the wire rod
At the same time that the Lo portion in _L1 reaches the defective product winding section 6, the hydraulic cylinder _OC2 on the truck 71 operates to retract its operating rod, and the guide rollers GR, GR
is moved to a position opposite to the good quality winding unit 5 so that the wire _L1 is wound up by the good quality winding unit 5. As a result, the wire L ₁ passes through the gap between the collar plates 61 in the defective product winding part component 60 and is wound in an aligned manner on the outer periphery of the peripheral wall plate 52 in the non-defective product winding part component 50 in the same way as in the previous case. It is being done. When the trolley 71 contacts the limit switch LS ₃ , the electromagnetic clutch 76 is switched and the screw rod 72 is reversely rotated, and when the cart 71 contacts the limit switch LS ₂ , the screw rod is similarly rotated in the normal direction, and the non-defective part of the wire L ₁ is removed. The non-defective products are wound in an aligned manner on the winding section 5.

In this way, the non-defective part of the wire L ₁ is wound up by the non-defective winding section 5, and when the defective part on the terminal side of the wire L ₁ reaches near the non-defective winding section 5, a cutter (not shown) (flying shear) occurs. actuated wire rod

When the shaft 9 is thereby moved rearward in the axial direction, each non-defective winding section component member 50 is moved inward, and the diameter of the non-defective winding section 5 is reduced. The defective product winding section component 60 is separated from the non-defective product winding section component 50 and tilted forward and inward, and the defective product winding section 6 is also reduced in diameter and wound around these respective winding sections 5 and 6. The removed wire can now be removed. Good product winding section 5, defective product winding section 6
When the removal of the wire L ₁ from the coil is completed, the hydraulic cylinder OC ₁ is operated again to move the shaft 9 forward in the axial direction, and reset the state shown in Fig. 5 to the state shown in Fig. 2. A new coil is set in the feeder 2 where C ₁ was set, and its starting end is welded to the terminal end of the coil C ₂ using the welding machine 3. Furthermore, the terminal end of the wire L ₁ is attached to the defective product winding section 6. After connecting to the winding portion 62 at , the motor M is activated and winding is performed in the same manner as described above.
