Description

[Detailed description of the invention]

The present invention relates to a ring-shaped wire focusing device that collects the ring-shaped wire into a coil by dropping the ring-shaped wire into a focusing device (focusing tab) from a conveyor or the like that continuously conveys the ring-shaped wire. be. Conventional methods for concentrating continuously conveyed ring-shaped wire rods into a coil shape include the following methods. Fig. 1 is a general diagram showing the process for converging ring-shaped wire into a coil shape, Fig. 2 a and b are a plan view and side view of the conventional device, and Fig. 2 c is C-C in Fig. 2 a.
It is an arrow view. That is, as shown in FIGS. 1 and 2, the wire rod 1 that exits the finishing mill 2, is water-cooled by a water-cooling device 3, and is formed into a continuous ring shape by a winder 4 is conveyed by a conveyor 5. It is transported and dropped into the focusing tab 6. Next, in order to receive the ring-shaped wire 1 in the focusing tab 6, the coil plate 8 is set at the upper limit position A-A as shown in FIG. A prismatic object protrudes, and on its outer periphery there are grid-like poles 8' and chamber doors 9' that regulate the outer diameter of the coil, and the ring-shaped wire 1 is bundled into a coil around the sail 7. . When the ring-shaped wire 1 begins to fall onto the coil plate 8, the coil plate 8 soon begins to descend and stops at the lower limit position B-B. Thereafter, the ring-shaped wire 1 is bundled into a coil, and when a certain amount is reached, the wire 1 is cut and separated into one wire coil 9. Further, the wire coil 9 is transferred from within the focusing tab 6 to the downender 14 by the horizontal movement of the sail 7. When the wire coil 9 is stored in the down-ender 14, the sail 7 descends, and after descending, it moves horizontally in the direction of the focusing tab 6, leaving the wire coil 9 inside the down-ender 14 in an empty state. return.
After the horizontal movement, the sail 7 rises again to its original state as shown in FIG. 2b. Wire coil 9 stored in down ender 14
As shown by the arrow in FIG. 2, as the down ender 14 tilts, it becomes horizontal and is transferred in the direction of the hanger 15. The transferred wire coil is loaded onto the bar of the hanger 15, passes through an inspection process not shown in the drawings, and is transported to a binding machine not shown in the drawings. The above is a conventional method for converging and moving ring-shaped wires, but this conventional method has the following drawbacks. The first is that the cross section of a normal sail is generally rectangular as shown in Figure 2, so the inner diameter of the wire coil is inevitably constrained in the long side direction of the rectangular cross section, so the roundness of the inner diameter is affected. Unfortunately, the inner diameter of the coil tends to be large in the long side direction of the sail cross section and small in the short side direction. (Fig. 2 plan view a). As a result, uneven wire rods may protrude from the ring during the tying stage, causing tying problems when the hoop guide of the tying machine (not shown in the figure) hits them, or cases in which the roundness of the coil inner diameter required by the user cannot be ensured. . The second problem is that the ring-shaped wire material bundled in the bundle tab 6 is not filled properly, resulting in a high coil height and thin coil, which causes the load to collapse after tying. If the wires are tied too tightly, there are problems such as buckling of the coil and damage to the wire. Furthermore, due to the high height of the coil, the unit consumption of binding materials such as binding hoops is poor, storage efficiency in warehouses, etc. is poor, and loading efficiency on ships during sea transportation is also poor. Thirdly, when moving a bundled wire coil, the sail itself is moved, which results in a considerable lag in the timing of focusing the next ring-shaped wire, which removes some of the coils deposited on the coil plate. The rising sail pushes up and causes a disturbance in the ring. Fourth, when moving a focused wire coil,
Between the coil plate notches provided for sail movement, the lower surface of the coil deposited on the coil plate sag due to its own weight (Fig. 2c), and while the coil is moving, the corners of the notch and the lower surface of the coil Due to contact, scratches are generated on the lower surface of the coil, and processing must be performed to ensure quality. Fifth, when the sail descends after the bundled wire coil is stored in the down ender, the inner surface of the coil and the lowered sail are in contact with each other, causing scratches on the inner surface of the coil. Sixthly, the ring-shaped wire rods that are bundled in the focusing tab are generally regulated by grid-like poles or the like fixed from the outer circumference of the coil, but such outer diameter regulating poles are used in the moving direction of the wire coil. Since it is not possible to arrange a ring-shaped wire rod, the focusing tab should be closed toward the center of the focusing tab to regulate the outer circumferential surface of the coil while the ring-shaped wire rod is being focused, and when moving the focused wire coil, it should be opened so as not to impede movement. Although a chamber door (9' in FIG. 2) is installed, conventionally the chamber door restricts the outer circumferential side of the coil at two points, so the regulating force is weak, and there are cases where the rings become uneven on the outer circumferential surface of the coil. There were other drawbacks. The present invention eliminates the drawbacks of these conventional methods, ensures the alignment of the inner and outer surfaces of the coil and the roundness of the inner diameter of the coil, and also makes it possible to manufacture a thick wire coil with an extremely low coil height. It is an object of the present invention to provide a converging device for ring-shaped wires, which allows the next convergence of ring-shaped wires to be carried out promptly and prevents scratches on the lower surface and inner surface of the coil. That is, the present invention provides a method for converging continuously conveyed ring-shaped wire rods into a coil shape and moving the converging method such that the ring-shaped wire rods dropped from the conveying device into the convergence tab always have a constant inner diameter true. A collection of ring-shaped wire rods using a sail having a cross section shaped to form a wire coil that maintains circularity, and dropping the ring-shaped wire rods while changing in the horizontal direction above the deposition position of the ring-shaped wire rods. As for the coil moving method, the sail is divided into two after the coil is focused, and the next ring-shaped wire is quickly focused using one of the sails,
A collection of ring-shaped wire rods, characterized in that the wire rod coil can be moved by the other sail without deteriorating its quality, and when both sails are lowered, they can be lowered without contacting the inner surface of the coil. It is a device. Next, the present invention will be explained in detail based on examples. The present invention has the following advantages: First, the cross section of the sail is changed from the conventional I-shaped cross section to the cross section shown in FIG. 3 in order to ensure the roundness of the inner diameter of the wire coil. Third, when moving the wire coil, the sail shown in FIG. 3 is divided into two,
The fourth feature is that one sail (5 in Figure 3 2) quickly converges the next ring-shaped wire rod, and the other sail (26 in Figure 3) moves the wire rod coil. When moving the wire coil using one of the divided sails (26 in Figure 3), the shape of the sail is designed to prevent the lower surface of the coil from hanging down in the notch of the coil plate and causing contact scratches. In order to support the front side of the coil in the moving direction, the coil is shaped with a step (Fig. 7). The fifth is sail 2
In order to prevent the occurrence of scratches on the inner surface of the coil due to contact between the inner surface of the coil and the sail when lowering the sail, the outer diameter of the sail is reduced and a link mechanism is used by the cylinder to allow the sail to be lowered. The sail shape is expandable and retractable (Fig. 8a, b). Sixthly, as a method for regulating the outer periphery of the coil by the chamber door of the ring-shaped wire material collected in the focusing tab, regulation can be performed at at least four points or more using a cylinder via a link mechanism (Fig. 6a, b) It has six characteristics as described above. Next, a method for converging ring-shaped wire rods using the apparatus of the present invention will be explained with reference to FIGS. 4a, 4b, and 5c and 5. Ring-shaped wire rod 1 conveyed by conveyor 5
is dropped from the end of the conveyor 5 into the focusing tab 6 and deposited on the coil plate 8 around the sail 7. In the device of the present invention,
By the method shown in Japanese Patent Application No. 54-45034,
The number and falling speed of the ring-shaped wire 1 per unit time are determined in advance from the relationship between the finish rolling speed of the ring-shaped wire 1 being conveyed and the speed of the conveyor 5, and the number of falling rings of the ring-shaped wire 1 per unit time and the falling speed are calculated based on these values. The deposition speed of the ring-shaped wire 1 is determined, and the motor 16 for raising and lowering the coil plate is driven according to this deposition speed, and the coil plate 8 is lowered via the chain 17 to move the ring-shaped wire 1 to the deposition position L-L. control so that it is always constant. Normally, by lowering the coil plate 8 in accordance with the deposition rate of the ring-shaped wire 1, the deposition position of the ring-shaped wire 1 can always be kept constant. Furthermore, the ring-shaped wire 1 dropped from the terminal end of the conveyor 5 into the focusing tab 6 is shown in FIGS. 4b and 4c.
As shown in the figure, the deposition position L-L of the ring-shaped wire 1 is
As shown in the figure, levers 22a, 22b, 22c, 22d, 22e are provided at five locations around the upper focusing tab 6, the upper part of which is rotatable by a pin 21.

Discs 24a, 24b, 24 rotated by 3e
For example, 22a, 22 by c, 24d, 24e
b, 22c, 22d, and 22e are moved in and out of the focusing tab 6 in this order as shown in FIG. The stacking position L-L of the ring-shaped wire 1 on the coil plate 8 is changed horizontally so that the ring-shaped wire 1 is deposited in an alternately distributed manner toward the outside of the coil plate 7 (toward the wall side of the focusing tab 6). let it fall. Normally, the speed at which the levers 22a, 22b, 22c, 22d, and 22e are moved in and out is set according to the falling speed of the ring-shaped wire 1, such that when the falling speed is fast, the speed is fast, and when the falling speed is slow, the speed is slow. 2
3b, 23c, 23d, and 23e, but if you want to obtain the desired dispersion state, use motor 2.
This can be obtained by changing the rotational speed of 3a, 23b, 23c, 23d, and 23e. Further, the levers 22a, 22b, 22c, 22d, 2
2e can also be easily obtained by adjusting the length of the turnbuckle 22' of each lever, as shown in FIG. 5, if a desired dispersion condition is desired. Further, as shown in FIG. 4a, the ring-shaped wire rod 1 is
In the case where the particles are deposited while being distributed alternately toward the outside of the sail 7 with the sail 7 at the center using the cylinder 33, a chamber door is provided that allows regulation at at least four points or more via the link mechanism 32 by the cylinder 33. , the outer diameter surface of the coil can be aligned. FIG. 6a is a diagram showing the chamber door 9' in which the ring-shaped wire rod 1 is being bundled.
1 closes toward the center of the central tab to regulate the outer diameter surface of the coil. FIG. 6b is a view showing the chamber door 9' just before the focused wire coil is moved, and the chamber door 9' is pulled by the cylinder 33 to the link 32 and fits into the pole 8' as shown in the figure, and the coil is moved. It will not be a hindrance. In this embodiment, levers are provided at five locations around the focusing tab, and these levers are moved in and out of the focusing tab in order in the circumferential direction of the focusing tab, but the number and locations of the levers are as follows: It is possible to select as appropriate depending on the condition of the ring-shaped wire being dropped, etc., and it is also possible to select the order of lever insertion and removal as appropriate depending on the condition of the ring-shaped wire being deposited. It is. Next, a method and apparatus for moving a focused coil using the cross-sectional sail of the present invention will be explained with reference to FIGS. 4a, b and c. After converging the ring-shaped wire 1 on the sail 7 (25 and 26 are part of the sail), the sail 7 is divided into a sail 25 and a sail 26, and the sail 25 is
The sail dimensions are reduced inward through the link mechanism 30 by sail-shaped expansion/contraction cylinders 25' provided at five cross-sectional locations (cross-sectional view in Figure 4 a), maintaining a space between the sail and the inner surface of the coil. In addition, the hydraulic cylinder 10 provided at the bottom of the sail 25 and the guide roll 13 provided on the side wall of the sail 25
Coil plate 8 (position shown in Figure 4 bB-B)
Descend directly below. Thereafter, as shown in Fig. 4b, a stepped shape (Fig. 7) is formed to support the front surface of the coil in the moving direction, so as to prevent the lower surface of the coil from sagging down to the notch of the coil plate and cause contact scratches. ) is transferred from inside the focusing tab 6 into the down ender 14 by the traverse hydraulic cylinder 11 and the guide roll 12. When the wire coil 9 is stored in the down ender 14, the sail 26 is contracted inward by the sail-shaped expansion/contraction cylinder 26' via the link mechanism 31 to maintain a space between it and the inner surface of the coil. At the top, under no load, it is lowered by the hydraulic lifting cylinder 27 and the guide roll 28, and after lowering, it is horizontally moved in the direction of the focusing tab 6 by the traverse cylinder 11 and returned. After moving into the focusing tab 6, the sail 26 is raised by a hydraulic lifting cylinder 27, and while rising, the sail 26 is raised by a sail-shaped expansion/contraction cylinder 26' to lift the link mechanism 3.
1, the sail expands outward, returns to its original position so as to hold the inner surface of the coil, and then merges with the sail 25 to return to its original state, as shown in FIG. 4b. During this time, the sail 25 is expanded by the sail-shaped expansion/contraction cylinder 25' via link mechanisms 30 provided at five cross-shaped locations, and returns to its original state so that it can hold the inner surface of the coil.
Immediately after the wire coil 9 is completely separated from the focusing tab 6 by the sail 26, it is raised by the hydraulic lifting cylinder 10 to start focusing the next ring-shaped wire. Therefore, sail 26 will merge with sail 25 while sail 25 is already converging the next ring-shaped wire. Here, the sail-shaped expansion and contraction mechanism will be explained with reference to FIGS. 8a and 8b, taking the sail 25 as an example. 8th
FIG. 8a is a plan view showing a situation in which the sail 25 is expanded, and FIG. 8b is a front view in which the sail 25 is similarly expanded. As shown in the figure, a base plate 56 is provided below the sail 25 to support the expansion/contraction bars 25b, and the base plate 56 is provided with a pin 54 for each expansion/contraction bar 25b. , connect it to the expansion/contraction bar 25b, and then connect it to the link 55 and pin 5.
It is connected to the sail 25 via 1. Also,
A cylinder 25' is provided below the base plate 56 and is fixed to the sail 25, and supports the base plate 56 via a rod 52. The pins 50, 51 and links 55 are provided at several locations above depending on the length of the expansion/contraction bar. 57
is a base plate 56 provided on the sail 25.
FIG. 8b is a view in which the base plate 56 is raised by the cylinder 25' via the rod 52, the link 55 becomes horizontal, and the expansion/contraction bar 25b is enlarged. Next, expansion bar 2
5b, when the base plate 56 is lowered by the cylinder 25', the expansion bar 25
b is lowered by the link mechanism and at the same time stops in close contact with the sail 25, and the expansion/contraction bar 25b contracts.
The same applies to the sail 26. By dividing the sail 7 into two in this way, horizontal movement of the wire coil can be carried out without significantly changing the conventional device, and the next convergence of the ring-shaped wire can be carried out immediately. becomes possible. Figure 9 is a graph comparing the coil height and coil thickness (coil inner and outer diameter difference/2) between the conventional method and the method of the present invention after bundling. It was found that the coil height was reduced by about 25%, and the coil thickness increased by about 11%, indicating that this is a manufacturing method that can increase the coil thickness. Table 1 is a table comparing the occurrence of scratches on the lower surface of the coil during movement of the focused coil between the conventional method and the method of the present invention, and it can be seen that the method of the present invention can completely prevent the occurrence of scratches.

[Table] As described above, according to the method of the present invention, the ring-shaped wire rod dropped into the focusing tab is controlled by using a chamber door having a link mechanism that can restrict the sail 7 and the outer diameter surface of the coil at at least four points. By dropping the ring-shaped wire while changing it in the horizontal direction above the stacking position, the inner and outer surfaces of the coil are well aligned and the inner diameter of the coil can be ensured. This eliminates all bundling troubles and fully satisfies the user's requirements. At the same time, the filling of the ring-shaped wire material is increased, making it possible to manufacture thick wire coils with an extremely low coil height, which makes bundling easier. This can greatly reduce the possibility of the wire coils collapsing later, and there is no need to use a binding machine to bind the wire rods more tightly than necessary to prevent the wire rods from collapsing. There are no problems such as sticking, the basic unit of binding materials such as binding hoops is good, the storage rate in warehouses is good, and the loading efficiency of ships during ocean transportation is also good. Sail 2 for focusing purpose
5 and sail 2, which is mainly used for moving wire coils.
By dividing the function into 6 parts, the sail 26 moves the first coil from inside the focusing tab, and at the same time the sail 25 rises and focuses the next ring-shaped wire, so the coil deposited on the coil plate can be removed. There is no possibility of the ring being pushed up by the rising sail and causing disturbance of the ring. On the other hand, when both sails descend, the sail shape is contracted via the link mechanism by the sail-shaped expansion and contraction cylinder. Since a space can be maintained between the inner surface of the coil and the inner surface of the coil, flaws on the inner surface of the coil can be prevented, and the shape of the sail 26 has a stepped shape that can support the lower surface of the coil on the front side in the direction of movement of the sail. Therefore,
This has an extremely large effect in that there is no possibility of the lower surface of the coil hanging down in the notch of the coil plate and causing contact scratches during the movement of the coil.
