Description

[Detailed description of the invention] Industrial application field This invention attaches a patch plate to the end of a coil around which wire is wound, and binds the wire with multiple binding materials at the part of the patch plate to prevent damage to the wire. This invention relates to a patch plate with a slippage prevention function for the binding material, which can prevent the binding material from shifting in the circumferential direction with respect to the patch plate and the coil, thereby preventing the coil from collapsing. .

Prior Art Wire products such as mild steel wire and stainless steel wire are produced by passing the material through a multi-stage rolling mill at a rolling mill to roll it to the desired wire diameter, and then cooling and winding it in the refining process.
After further inspection, it is shipped from the factory in the form of a coil. That is, in the refining process, a coil formed by winding a wire rod is loaded onto a coil conveying facility that circulates within the factory, and is subjected to refining operations such as inspection, terminal cutting, and bundling. This coil conveyance equipment is
In general, a conveyor has a hook that extends horizontally, and as shown in FIG. It is transported in a hung state.

The coils carried out from the winding machine by the hook conveyor are not yet bundled, and each wound wire rod is in a free state without close contact. Therefore, the coil 10 is bound with binding materials 18 at a plurality of equally spaced locations by an automatic binding machine (not shown) (see FIG. 12), and shipped in this packaging to a customer. As the binding material 18, a hoop made of wire and a high-tensile steel strip is preferably used.

Problems to be Solved by the Invention As described above, coils are tied by passing the coils suspended and supported by a hook conveyor through an automatic binding machine, and then delivered to a collection site by the conveyor. Therefore, until the bundled coils are shipped from the factory, there is almost no possibility that the bundled coils will collapse or that their end faces will have scratches or scratches.

However, at the stage after it is shipped from the factory, for example, when a large number of coils are loaded onto the back of a truck and transported, or when the goods are handled after reaching the customer, who is a secondary processor of wire rods, The coil is often unloaded, resulting in various scratches on the coil, and these scratches generally have an adverse effect on the secondary processing of the wire. In many cases, when handling cargo at the customer's end,
The above-mentioned hook conveyor is not used, and the work generally involves winding the band sling around a coil and lifting and moving the sling with a crane. When a coil is lifted with a sling in this way, stress is concentrated in one part of the coil, causing each wire that makes up the coil to locally deform into a fan shape, loosening the hoop and causing it to shift in the circumferential direction. This causes the load to collapse from being rolled up in an orderly manner.

If the packaging of the coil is distorted in this way, the wire rods or the wire rods rub against each other and the binding material such as a hoop excessively, causing scratches. In addition, coils are generally collected and stored in large numbers horizontally or vertically, but during this collection process, the coils rub or collide with each other, so it is common for coils to be placed horizontally or vertically next to each other. Many scratches and scratches occur on the end faces of the coils that meet each other. Furthermore, scratches may occur when the hook of a crane collides with the end face of the coil during cargo handling, and currently 70 to 80% of abrasions and other scratches are concentrated on the end face of the coil. Since these scratches seriously impede the secondary processing of the wire, it is necessary to repair the scratches using a grinder or the like, and this is cited as a major cause of lowering work efficiency.

In addition, from the viewpoint of transportation and inventory management, it is preferable to bundle each coil (small bundle) and then bundle the two coils with their ends facing each other (large bundle), and it is preferable to bundle the two coils with their ends facing each other (large bundle). It is often done.
However, in this case, if the above-mentioned band sling is used to hoist the items all at once, there is a tendency for the collapse of the load to further expand.

Therefore, a ring to prevent the binding material from slipping is attached to the end face of the coil, and a corrugated cardboard sheet or plywood sheet is attached to the coil for binding. For example, as shown in FIG.
The ring-shaped wire 20a is provided with a plurality of small-diameter ring portions 20b (the number corresponding to the number of binding materials), and the ring portions 20b are
By inserting and binding the binding material 18 through the coil 10, the binding material 18 is prevented from shifting in the circumferential direction with respect to the coil 10. But in this case,
Since it is necessary to insert the binding material 18 into the ring portion 20b, automatic binding is not possible, and therefore the slippage prevention ring 2
The installation of the 0 requires manual labor, which has the drawback of reducing work efficiency.

Corrugated cardboard sheets are also installed to prevent scratches on the end faces of the coils, but since these are sensitive to moisture and easily tear, they are of no use as they tear or tear under the mechanical force of binding, and are still used to prevent scratches on the end faces of the coils. The reality is that the occurrence of scratches cannot be prevented. It is also possible to apply a plywood board to the end face of the coil, but the plywood board is susceptible to cracking due to its strength and has the same drawback. Moreover, depending on the specifications, the coil may be completely immersed in oil in an oil tank while still in a bundled state, and the oil may be applied to the wire surface. It is also pointed out that it absorbs into the water and becomes useless after that.

Therefore, one proposal for dealing with the various problems mentioned above has been filed by the present applicant as an invention entitled "Coil binding method" in Japanese Patent Application No. 310636/1983.
In this invention, coils are bound with a binding material made of hoops or wire, and at that time, at least one end surface of the coil is provided with mechanical strength, a certain degree of rigidity, and a moderate The purpose of this method is to bind caulking plates made of materials such as semi-rigid foamed polyethylene in an aligned manner, which has the same elasticity as well as durability, shock-reduction properties, and economic efficiency.

Due to its material properties, this patch plate has moderate elasticity, so the binding material bites into the patch plate, and the binding deforms the edge of the patch plate, making it come into close contact with the coil. It becomes difficult for the load to collapse. Furthermore, it is possible to effectively prevent the end face of the coil from being scratched, and in this respect it can be highly evaluated. However, even when shipped in this packaging, as mentioned above, the binding material may be damaged by stress concentration caused by vibrations and shocks during transportation by truck, or by harsh handling of the cargo after it reaches the customer. The reality is that it slips on the top in the circumferential direction. Therefore, there is a serious problem that the binding material continues to be misaligned with respect to the coil, causing the coil to collapse.

Purpose of the invention This invention was proposed in order to solve the above-mentioned drawbacks that occur when handling coils, and effectively suppresses displacement of the binding material in the circumferential direction with respect to the coil. It is an object of the present invention to provide a means for preventing loads from collapsing during handling, and also for preventing scratches concentrated on the end faces of the coils.

Means for Solving the Problems In order to overcome the above-mentioned problems and achieve the intended purpose, the coil binding material slip prevention plate according to the present invention is applied to the end face of the coil around which the wire is wound. In a ring-shaped cover plate which is bound together with the coil by binding material at multiple locations, the binding material is accommodated on the outer surface of the ring-shaped cover plate and in the circumferential direction so that the binding material can be attached and removed from the outside of the plate. The present invention is characterized in that the movement of the binding material in the circumferential direction can be restricted by forming restriction portions at required intervals and accommodating the binding material in the restriction portions.

Embodiments Next, a preferred embodiment of the slip-preventing pad for coil binding material according to the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a preferred embodiment of the caul plate according to the present invention.
A plurality of grooves (four in this embodiment) functioning as regulating portions 24 are bored at predetermined intervals in the circumferential direction on one side of the ring-shaped backing plate 22 having a required thickness. This regulating portion 24
For example, when the coil 10 is bound by six binding materials 18, the regulating portions 24 are provided in six locations at predetermined intervals in the circumferential direction of the backing plate 22. . As shown in FIG. 8, by exposing the binding material 18 into the groove 24 and binding, the binding material 18 will not shift in the circumferential direction with respect to the coil 10.

The material for the backing plate 22 must meet the difficult conditions of handling the coils and post-processing the coils, that is, have mechanical strength, a certain degree of rigidity, and appropriate elasticity. Moreover, semi-rigid foamed polyethylene, which has comprehensive properties such as durability, impact-reducing properties, and economic efficiency, is preferably used.

2 and 3 show another embodiment of the present invention, in which a plurality of grooves functioning as regulating portions 24 are formed in the circumferential direction on the outer peripheral surface of the backing plate 22 shown in FIG. Holes are drilled at predetermined intervals. This patch plate 22 is set so that, when the patch plate 22 is attached to the end face of the coil 10, the groove 24 is positioned so as to protrude outward in the radial direction from the outer circumferential surface of the coil 10. By tying the binding material 18 facing the concave groove 24, it is possible to prevent the binding material 18 from shifting in the circumferential direction with respect to the coil 10.

Further, the backing plate 22 shown in FIG. 3 has grooves formed at predetermined intervals in the circumferential direction on its inner circumferential surface, which function as regulating portions 24. This patch plate 22 is set so that, when the patch plate 22 is attached to the end face of the coil 10, the groove 24 is positioned so as to protrude radially inward from the inner circumferential surface of the coil 10. Therefore, by tying the binding material 18 so as to face the groove 24, it is possible to prevent the binding material 18 from shifting in the circumferential direction of the coil 10.

FIG. 4 shows yet another embodiment of the present invention, in which a plurality of convex portions 24 protruding from one side of the patch plate 22 are provided at predetermined intervals in the circumferential direction of the patch plate 22. be. In this case as well, the convex portion 2
4 along the binding material 18, the binding material 1
8 can be prevented from shifting in the circumferential direction. In this case, as shown in FIG.
If the binding material 18 is positioned so as to be sandwiched from the left and right sides by the binding materials 4 and 24, the displacement of the binding material 18 can be more effectively prevented.

5 and 6 show still another embodiment of the present invention, in which the outer peripheral surface of the patch plate 22 shown in FIG. A plurality of convex portions 24 protruding radially outward from the outer peripheral surface of the coil 10 are provided at predetermined intervals in the circumferential direction of the backing plate 22. In other words, this convex portion 2
4 functions as a regulating portion that prevents the binding material 18 from shifting in the circumferential direction with respect to the coil 10. Also the 6th
The caul plate 22 shown in the figure has a convex portion 24 that protrudes radially inward on the inner peripheral surface of the abutment plate 22.
A plurality of protrusions are provided at predetermined intervals in the circumferential direction.
The convex portion 24 is configured to protrude radially inward from the inner circumferential surface of the coil 10 when the corresponding body 22 is attached to the coil 10.

In addition, in the caul plates 22 shown in FIGS. 5 and 6, as explained in connection with FIG. By sandwiching the binding material 18 between 24, 24, displacement of the binding material 18 can be effectively prevented.

FIG. 7 shows yet another embodiment of the present invention, in which quarter-circular arc segments 22a are overlapped and bonded by a required dimension at each end to form a ring-shaped pad as a whole. A plate 22 is formed. Therefore, a protruding step portion 24 is formed on the side surface of the backing plate 22 at the overlapping portion thereof, and this step portion 24 functions as a regulating portion for the binding material 18.

Next, the actual use of the coil binding material slip prevention plate according to the present invention constructed as described above will be explained. As shown in Figure 8, coil 1
Attach the patch plate 22 to both ends of the plate 0 so that the groove 24 thereof appears on the outer surface. In this case, the grooves 24, 24 of both the backing plates 22, 22 are positioned in advance so that they are aligned in the axial direction. After doing this, in the concave grooves 24, 24 aligned at four locations in the circumferential direction of the backing plate 22,
Binding is performed with the binding material 18 facing each other in common.
Because the patch plate 22 has appropriate elasticity due to its material properties, the patch plate 22 can be bound by bundling.
2 deforms and comes into close contact with the coil 10, and the binding material 18 faces into the groove 24.
The binding material 18 does not shift in the circumferential direction with respect to the coil 10, and therefore, it is possible to effectively prevent the load from collapsing.

In addition, according to the caul plate 22 in this embodiment, in the above-mentioned coil conveyance equipment, the coil 1 before bundling is
The coil 10 is conveyed to an automatic binding machine with the ring-shaped backing plates 22, 22 hooked to the hook 16 of the conveyor that suspends the coil 10. Once the items are addressed, the automatic binding machine can perform binding using a binding material 18 such as a wire or a hoop. That is, it is not necessarily necessary to align the regulating portions of the backing plate facing both end surfaces in the axial direction. Further, even when applying a patch plate to one end surface, it is not necessary to make the binding material face the regulating portion of the patch plate.

Further, when a plurality of coils 10, 10 are bundled together as described above, there is no space between adjacent coils 10.
It is only necessary to interpose the two backing plates 22.

In addition, in the embodiment shown in FIGS. 4 to 7, as shown as an example in FIG.
By positioning and binding the binding material 18 so as to sandwich the binding material 18, the binding material 18 can be effectively prevented from shifting in the circumferential direction with respect to the coil 10.

Effects of the Invention As described above, according to the coil binding material slip prevention plate according to the present invention, the binding material can be attached and removed from the outside of the plate on the outer surface of the ring-shaped patch plate and in the circumferential direction. It is characterized in that restricting portions represented by concave grooves and convex portions that can be accommodated freely are formed at required intervals. In this way, the regulating part is configured so that the binding material can be accommodated from the outside of the board, so there is no need for complicated insertion work into the hole, etc.
The binding work can be performed extremely easily, and the binding material can be prevented from shifting in the circumferential direction with respect to the coil. As a result, even if the coils are transported after bundling and subjected to severe cargo handling at the customer's site, it is possible to prevent the cargo from collapsing and effectively prevent damage to the coils. The same applies when two or more coils are bundled together. Furthermore, with the conventional anti-slip ring, it is necessary to manually attach the ring to the binding material, making it impossible to automatically bundle the coils.
It was extremely inefficient. However, in this invention,
By simply hooking the backing plate onto the hook of the hook conveyor and passing it through the automatic binding machine, the binding will be done automatically.
Therefore, the efficiency of continuous work can be improved.
