Description

Wire coil assembly device and wire coil assembly method

Technical Field

The present invention relates to a wire coil collecting device and a wire coil collecting method.

Background

In the wire coil production line, a wire rolled by a wire rolling mill is formed into a loop-shaped wire coil that is continuous by a drawing head, and is conveyed while being unwound on a conveyor belt, and is collected in a coil collecting device.

As a conventional coil assembly device, there is known a device for assembling an introduced wire coil without generating a flaw in the coil inner diameter portion (for example, patent documents 1 and 2).

The coil assembly device of patent document 1 includes, in a cylindrical body: a pole bottom body; a rod formed by erecting a plurality of rod-shaped bodies from a rod bottom body; and a lifting cylinder which is lifted from the rod bottom body and protrudes from between the rod-shaped bodies of the rod. The inner diameter portion of the wire coil dropped from the conveyor belt is inserted into the rod, and the lifting cylinder lifted from the rod bottom body is integrated on the rod bottom body without generating flaws or bending on the wire coil.

Problems to be solved by the invention

However, the coil assembly device of patent document 1 has the following cases: the coil inner diameter portion of the wire coil dropped from the conveyor belt continuously contacts the rod, thereby generating a worn portion, which is deformed to generate burrs. If the wire coil is collected in a state where burrs are generated in the rod, the dropped wire coil may contact the burrs, and flaws may be generated in the inner diameter portion of the coil. In addition, when the wire coil that has been assembled is pulled out from the rod, the coil inner diameter portion of the wire coil is caught by burrs of the rod, and the wire coil cannot be pulled out from the rod normally.

In addition, the coil assembly device of patent document 2 may also include the following: a part of the wire coil falling from the conveyor belt continuously contacts the core member, thereby generating a worn portion, which is deformed to generate burrs. When the wire coil is collected in a state where burrs are generated in the core member, the dropped wire coil contacts the burrs of the core member, and flaws are generated in the coil inner diameter portion. When the integrated wire coil is pulled out from the core member, the coil inner diameter portion of the wire coil is caught by burrs of the core member, and the wire coil cannot be pulled out from the core member normally.

Accordingly, in patent document 1, the entire rod is replaced with a new product member at the time when the rod is worn, and in patent document 2, the entire core member is replaced with a new product member at the time when the core member is worn, whereby flaws on the inner surface of the wire coil can be prevented or normal extraction from the wire coil can be performed.

However, the replacement of the entire rod of patent document 1 and the replacement of the entire core member of patent document 2 greatly increase the cost of the component replacement. In addition, since the work time for component replacement becomes long, the maintenance cost also increases.

The present invention has been made in view of the unsolved problem of the conventional example, and an object thereof is to provide a wire coil assembling device and a wire coil assembling method capable of assembling a high-quality wire coil free from flaws or the like at an inner diameter portion of the coil while reducing repair costs of a set lifter.

Means for solving the problems

In order to achieve the above object, a wire coil collecting device according to an embodiment of the present invention includes: a chamber into which a wire coil conveyed in a ring shape is introduced from above; a nose cone arranged at an upper portion in the chamber to pass the introduced wire coil therethrough; a coil plate which is arranged in the chamber in a freely liftable manner and integrates the wire coil falling from the head cone; and a sleeve lifter (japanese) disposed to extend in the up-down direction between the lower part of the head cone and the coil plate, for guiding the coil inner diameter part of the wire coil falling from the head cone, the sleeve lifter including a core material and a surface material detachably fixed to the core material.

In the wire coil assembly method according to one aspect of the present invention, in the wire coil assembly method using the wire coil assembly device, when damage occurs on the lifting surface of the surface material due to contact with the coil inner diameter portion of the dropped wire coil, the surface material at least damaged is removed from the core material, and a new surface material is attached to the core material. Here, the damage is abrasion or the like caused by continuous contact of the coil inner diameter portion of the wire coil.

According to the wire coil assembly device and the wire coil assembly method of the present invention, the repair cost of the sleeve lifter can be reduced, and the high-quality wire coil, which does not cause defects or the like in the inner diameter portion of the coil, can be assembled.

A conveyor 9 for introducing the wire coil C formed into a loop shape upstream of the wire coil production line into the chamber 3 in a horizontally laid state is disposed near the opening 3a of the chamber 3.

As shown in fig. 2, the sleeve lifter 5 is formed of a rolled steel material SS400 for general construction as a raw material, and is composed of a core material 10 formed in a rectangular cross-sectional shape and extending in the up-down direction in the longitudinal direction, and a surface material 11 surrounding the periphery of the core material 10 in the longitudinal direction and fixed to the core material 10.

The surface material 11 is formed in a rectangular cylindrical shape, and is composed of first to fourth peripheral panels 12, 13, 14, 15 surrounding the periphery of the core material 10 in the longitudinal direction.

The first peripheral panel 12 is formed by continuously disposing the same rectangular parallelepiped split plates 12a to 12f along the longitudinal direction of the core 10. The other second to fourth plates 13 to 15 are also constituted by a plurality of rectangular parallelepiped split plates 13a to 13f, 14a to 14f, 15a to 15f obtained by dividing the dimension in the longitudinal direction equally, and are arranged continuously along the longitudinal direction of the core 10 (the split plates 13b to 13f are not shown in fig. 2).

Next, a specific fixing structure of the core material 10 and the first to fourth peripheral panels 12, 13, 14, 15 will be described with reference to fig. 2 and 3.

Fig. 3 shows a division plate 12a constituting a first peripheral panel 12, a division plate 13a constituting a second peripheral panel 13, a division plate 13a constituting a third peripheral panel 14, and a division plate 15a constituting a fourth peripheral panel 15, which surround the periphery of the core 10 in a quadrangular cylindrical shape.

The dividing plates 12a and 14a are arranged in an H-shape in contact with the short side surfaces 10a and 10b of the core 10. Spot facing 16 is formed at the center of the surfaces of the dividing plates 12a and 14a, screw holes 17 are formed at the bottoms of the spot facing 16, and screw holes 18 are formed at positions corresponding to the screw holes 17 of the core 10. The split plates 12a and 14a are fixed to the core 10 by screwing the screw portions of the fixing bolts 19 inserted from the spot facing 16 into the screw holes 17 and 18. Further, although not shown, the spot facing 16 of the dividing plate 12a is formed with 2 portions in the upper and lower directions (see fig. 2), screw holes 17 and 18 corresponding to the spot facing 16 are also formed, and the dividing plate 12a is detachably fixed to the core 10 by two fixing bolts 19. Although not shown, the partition plate 14a is also detachably fixed to the core 10 by two fixing bolts 19.

The division plates 12b to 12f constituting the first peripheral panel 12 other than the division plate 12a are also fixed in a detachable manner continuously along the longitudinal direction of the core 10, and the division plates 14b to 14f constituting the third peripheral panel 14 other than the division plate 14a are also fixed in a detachable manner continuously along the longitudinal direction of the core 10. Here, the bolt heads of the fixing bolts 19 are not protruded from the surfaces of the dividing plates 12a to 12f and 14a to 14f, and are positioned inside the spot facing 16.

On the other hand, the dividing plates 13a and 15a of fig. 3 are arranged in a quadrangular tubular shape together with the dividing plates 12a and 14a fixed to the core 10. Spot facing 20 is formed on the surfaces of both ends in the longitudinal direction of the dividing plates 12a, 14a, screw holes 21 are formed at the bottoms of the spot facing 20, and screw holes 22 are formed at positions corresponding to the screw holes 21 of the dividing plates 13a, 15a. The screw portions of the fixing bolts 23 inserted from the spot facing 20 are screwed into the screw holes 21 and 22, whereby the split plates 13a and 15a are fixed to the split plates 12a and 14a. The spot facing 20 formed at both ends in the longitudinal direction of the dividing plate 12a has two portions (see fig. 2) formed in the upper and lower directions, but screw holes 21 and 22 corresponding to the spot facing 20 are also formed, and the dividing plates 13a and 15a are fixed to the dividing plates 12a and 14a by screwing two fixing bolts 23, respectively.

Here, the bolt heads of the fixing bolts 23 are not protruded from the surfaces of the dividing plates 12a to 12f and 14a to 14f, and are positioned inside the spot facing 20.

Next, the wire coil assembling operation using the wire coil assembling device 1 according to the present embodiment will be described with reference to fig. 1, 4, and 5. In addition, at the initial stage of the coil C integration operation shown in fig. 1, the adjusting portion 7 is advanced in the chamber 3.

As shown in fig. 1, the wire coil C formed in a loop shape upstream of the wire coil production line falls down to the opening 3a of the chamber 3 in a state of being horizontally tilted on the conveyor 9. The wire coil C is guided by the rotating blades 4, and is dispersed in the chamber 3, and falls down while contacting the nose cone 6. Thus, the wire coil C is temporarily accumulated in the adjusting portion 7 while being positioned by the nose cone 6. The coil plate 8 is raised to a predetermined height to receive the wire coil C accumulated in the adjusting unit 7.

As shown in fig. 4, the wire coil C temporarily accumulated in the adjusting portion 7 is retracted from the chamber 3 by the adjusting portion 7 and falls down onto the coil plate 8. The wire coil C immediately before falling onto the coil plate 8 is guided by contact with the surface material 11 of the set lifter 5, and falls to the center of the coil plate 8. The coil plate 8 gradually descends as the amount of the wire coils C accumulated increases, and when a certain amount of the wire coils C are loaded, the descending operation of the coil plate 8 is stopped.

Next, as shown in fig. 5, the set lifter 5 is moved toward the bucket 2 disposed outside the chamber 3, so that the wire coil C mounted on the coil plate 8 is transferred to the bucket 2. Further, the sleeve lifter 5 is lowered to be pulled out from the inner diameter portion of the wire coil C, so that the bucket 2 on which the wire coil C is placed is moved to another place such as a wire coil storage place.

Here, in the wire coil collecting operation using the wire coil collecting device 1, the repairing operation of the set lifter 5 will be described below in the case where the coil inner diameter portion of the wire coil C is continuously in contact with a part of the surface material 11 of the set lifter 5, and wear occurs at the continuously contacted portion. In the kit lifter 5 according to the present embodiment, the divided plates 12d and 15d of the first and fourth peripheral panels 12 and 15 constituting fig. 2 generate wear portions.

The worn-out partition plate 12d is detached from the core 10 and the partition plates 13d and 15d by unscrewing the fixing bolts 19 screwed into the core 10 and the fixing bolts 23 screwed into the partition plates 13d and 15 d.

The worn-out partition plate 15d is detached from the partition plate 14d by unscrewing the fixing bolts 23 screwed into the partition plate 14 d.

Then, instead of the worn-out divided plates 12d, 14d, new divided plates 12d, 14d are fixed using fixing bolts 19, 23, thereby completing the repair work of the set lifter 5.

Next, effects of the present embodiment will be described.

In the coil winding operation using the coil winding device 1 of the present embodiment, when the coil inner diameter portion of the coil winding C is continuously in contact with the surface material 11 of the set lifter 5 and the surface material 11 is worn out due to the falling down, only at least 1 of the first peripheral panel 12 (the dividing plates 12a to 12 f), the second peripheral panel 13 (the dividing plates 13a to 13 f), the third peripheral panel 14 (the dividing plates 14a to 14 f), and the fourth peripheral panel 15 (the dividing plates 15a to 15 f) constituting the surface material 11 is replaced, so that the repair operation of the set lifter 5 can be easily performed.

Therefore, in the present embodiment, since the whole of the worn-out set lifter 5 is not replaced with a new component, the repair of the set lifter 5 can be completed in a short time by only replacing the worn-out dividing plate, and therefore the repair cost of the set lifter 5 can be greatly reduced.

In addition, a part (predetermined dividing plate) of the surface material 11 that has worn out can be replaced with a new dividing plate to repair the set lifter 5, and even if the coil inner diameter portion of the wire coil C immediately before falling onto the coil plate 8 contacts the surface material 11 of the set lifter 5, no defect occurs in the coil inner diameter portion, and a high-quality wire coil can be integrated.

When the set lifter is pulled out from the wire coil C transferred to the bucket 2, the surface material 11 of the set lifter 5 after repair is free from a portion where burrs or the like are caught in the coil inner diameter portion of the wire coil, so that the set lifter 5 can be pulled out from the wire coil C normally.

The kit lifter 5 of the present embodiment is constituted by the first to fourth peripheral panels 12, 13, 14, 15 having a quadrangular tubular shape surrounding the periphery of the core 10 in the longitudinal direction, but the gist of the present invention is not limited to this, and may be a plurality of circular arc-shaped or polygonal plates surrounding the periphery of the core 10 in the longitudinal direction. The first to fourth peripheral panels 12, 13, 14, 15 are formed by a plurality of rectangular parallelepiped split plates 12a to 12f, 13a to 13f, 14a to 14f, 15a to 15f of the same shape, but split plates of different shapes may be continuous in the longitudinal direction of the core 10. As shown in fig. 3, the kit lifter 5 of the present embodiment has a plate-like structure having a pair of short side surfaces 10a and 10b and a long side surface, which is parallel to the long side direction, but the gist of the present invention is not limited to this, and for example, a cylindrical member, a member having an H-shaped cross section orthogonal to the long side direction, or other members having various shapes may be applied.
