Description

  The present invention relates to a slit coil hacker for sorting and lifting a plurality of adjacent slit coils.

  In a roll forming facility, a wide rolled coil of raw material (called a raw coil), in which a metal strip such as a steel strip is wound in a coil shape, is slit to a predetermined width by a slitter according to the product to be rolled. Then, it is divided into a plurality of slit coils, and each is bound by a binding band that tightens the outer periphery of the coil.

In this case, not all of the divided slit coils may include slit coils having different widths.
For example, if the slit width (plate width) necessary for the forming line is 200 mm for a raw coil having a coil width of 1300 mm, the slit width is 200 × 6 = 1200 mm, and the yield loss is 100 mm (= 1300-1200). Occurs.
In that case, if a slit coil having a slit width of 300 mm is required in another forming line, the yield loss becomes zero when a combination of 200 mm × 5 and 300 mm × 1 is selected. In this case, there are five slit coils having a slit width of 200 mm and one slit coil having a slit width of 300 mm.
As described above, when the raw coil is slit into a plurality of strips with a slitter, when the slit coils having different widths are included, the plurality of slit coils (referred to as a slit coil group) are hung on a hook of a crane (not shown). Once a large hacker is taken to the sorting table. As shown in FIG. 10, the conveyed slit coil group G is placed on a sorting table (coil mounting table) 2 in an adjacent state in which slit coils 1 a having a slit width of 300 mm are arranged on the end side. A slit coil having a slit width of 200 mm is denoted by 1b.
As shown in the figure, the sorting table 2 normally includes a receiving material 2a inclined with respect to the floor surface F and a twisted material 2b perpendicular to the receiving material 2a (inclined with respect to the vertical line), As shown in the figure, the slit coil group G is placed on the receiving member 2a in an inclined state so as to be supported by the twisting member 2b.

The plurality of slit coils placed on the sorting table 2 are sorted for each slit width and each is conveyed to a predetermined location.
The work for sorting on the sorting table will be described in the above case. First, the large hacker 5 used for transporting the slit coil group is replaced with a small hacker 5 ', and the small hacker 5' uses the end side. The slit coil 1a having a width of 300 mm is suspended and conveyed to a predetermined location.
Next, the small hacker 5 ′ is replaced with the large hacker 5 again, and the remaining five coils of the slit coil group having a width of 200 mm are collectively suspended and conveyed to a predetermined place.
The difference between the large and small hackers is basically the difference between the long and short rod-like suspension parts 12 and 12 'that are inserted into the coil's central space S and suspend the coil. There are large and small differences.

The hacker 7 (slit coil handling device) of Patent Document 1 shown in FIG. 11 enables each slit coil to be laterally banded (bound with a binding band in the radial direction from the circumference to the outer periphery). In order to achieve this, the separation mechanism 9 for separating adjacent slit coils from each other is provided. A plurality of sliders 9a are slidably provided on the lower frame 8 of the hacker 7, and adjacent ones of the sliders are arranged. It is a hacker (handling device) for a slit coil that can be separated by a predetermined distance.
The plurality of sliders 9a are provided on a base member 9b fixed to the lower frame 8, and are driven and slid by a ball screw 9c. An interval between adjacent ones is defined by a wire 9d.

JP2007-118062

In the above conventional method in which the slit coil group including slit coils having different slit widths is sorted by the slit width using the large hacker 5 and the small hacker 5 ', the hacker is changed from a large one to a small one. The work to replace requires labor and time, and the workability is low.
Also, when multiple molding lines in the factory are in operation, crane work is also required on each molding line, so if time is taken for hacker replacement work, "waiting for cranes" frequently occurs. The production line may stop.

  Not only when including slit coils with different slit widths as described above, but also in the case of slit coil groups with all the same slit widths, it is necessary to lift the slit coil on the end side with a large hacker instead of a small hacker In this case, the same problem occurs.

  The hacker of Patent Document 1 lifts a plurality of slit coils together and separates the slit coils from each other, and cannot be used for lifting only the slit coil on the end side.

  The present invention has been made to eliminate the above-described conventional drawbacks, and when a large hacker is hung on a crane hook, a lifting operation for sorting and lifting a plurality of adjacent slit coils is performed with a dedicated small size. An object of the present invention is to provide a slit coil hacker that can be efficiently performed without the need for replacement with a hacker, and that has a simple structure and is inexpensive.

The invention of claim 1 that solves the above-mentioned problem is a slit coil hacker for sorting and lifting a plurality of adjacent slit coils,
There is a horizontal bar-like suspension part that is inserted into the central space of the slit coil and lifts the slit coil, and a raising member for raising a part of the upper surface of the rod-like suspension part is provided on the upper surface of the rod-like suspension part. It is attached detachably.

  Claim 2 is the slit coil hacker according to claim 1, wherein pin holes are respectively formed at a plurality of positions spaced in the longitudinal direction of the suspended portion on the upper surface of the rod-shaped suspended portion, and the pin for attaching the raising member to each pin hole. Is inserted in a detachable manner, and pin holes are formed in the lower surface of the raising member to fit the pins.

  According to a third aspect of the present invention, in the slit coil hacker of the first or second aspect, a pin hole is formed in the upper surface of the raising member, and a pin for preventing the coil to fall is detachably inserted into the pin hole.

  A fourth aspect of the present invention provides the slit coil hacker according to any one of the first to third aspects, wherein the raising member is disposed on a vertical line passing through the center of gravity of the hacker in the rod-like suspension portion. It is characterized by that.

According to the slit coil hacker of the present invention, the raising member for raising a part of the upper surface of the rod-like suspension part is detachably attached to the upper surface of the rod-like suspension part. When the rod-shaped suspension part is inserted into the center space of the slit coil and the height of the hacker is slightly raised by aligning the raised part with the position of the slit coil on the end side of the slit coil group on the coil mounting base, only the slit coil on the end side Will rise slightly. Next, when the hacker is moved back horizontally to remove the bar-like suspension from the central space of the slit coil group, and then the hacker is lifted, only the slit coil on the end side is lifted.
This slit coil hacker can be used as a normal large hacker with a long bar-like suspension when the raising member is removed. That is, it has a function as a large hacker capable of lifting the entire slit coil group and a function as a small hacker capable of lifting only one slit coil.
Therefore, it is suitable for use in coil suspension work when a slit coil group including slit coils having different slit widths is sorted for each slit width.
That is, the slit coil group slit into a plurality of strips by a slitter is once transported to a sorting table using the slit coil hacker of the present invention with the raised member removed, and the raised member is attached to the slit coil hacker and sorted. Only slit coils having different slit widths on the end side in the slit coil group on the table can be lifted and conveyed to a predetermined place. Thus, the work of exchanging with a small hacker becomes unnecessary, and the workability of the coil hanging work when sorting the slit coil group including the slit coils having different slit widths for each slit width is improved.
However, the present invention can also be applied to the case where only the slit coils on the end side are lifted even in the case of slit coil groups having the same slit width.
Also, the number of slit coils on the end side to be lifted is not limited to one, but may be a plurality.

It is a figure explaining the operation | work which lifts the slit coil of the end side on a sorting stand (coil mounting base) using the slit coil hacker of one Example of this invention, The state which made the hacker approach the slit coil group is shown. FIG. 1 shows a state in which a hacker's rod-like suspension is inserted into the central space of the slit coil following FIG. FIG. 2 shows a state in which the hacker is slightly raised and the slit coil on the end side is slightly raised.

It is a figure for demonstrating the conventional operation | work in the case of lifting only the slit coil of the edge side from which the slit width differs in the some slit coil placed on the sorting stand. It is a figure which shows the conventional hacker for slit coils.

  Hereinafter, embodiments of the slit coil hacker of the present invention will be described with reference to FIGS.

FIG. 1 is a diagram for explaining an operation of lifting a slit coil 1a on an end side on a sorting table (coil mounting table) 2 using a slit coil hacker 11 according to an embodiment of the present invention. 11 is simply referred to as a hacker).
As with the slit coil group G placed on the sorting table 2, the slit coil 1a on the end side has a slit width of 300 mm, and the other five slit coils 1b have six slits having a slit width of 200 mm, as described in FIG. This is the case with a coil.

As shown in FIG. 1 and the like, the sorting table 2 normally includes a receiving material 2a inclined with respect to the floor surface F and a twisted material 2b perpendicular to the receiving material 2a (inclined with respect to the vertical line). As shown in the figure, the slit coil group G is placed on the receiving member 2a in an inclined state so as to be supported by the twisting member 2b.
As shown in FIG. 8, the receiving material 2a is on the left and right sides when viewed from the front of the coil, and has receiving surfaces 2c that are inclined inwardly to receive the lower surface of the coil 1, opposite to the twisted material 2b of the left and right receiving materials 2a A transverse member 2d (see FIG. 1) connecting one end of the side is welded and fixed to the lower surface of the receiving member 2a, and is inclined with respect to the floor surface F as described above. Is fixed. A cross member 2e that connects the other end of the receiving member 2a is welded and fixed to the other end surface of the receiving member 2a, and an oblique member 2f that supports the twisted member 2b is fixed to the upper surface of the cross member 2e by welding.

  The main body 5 of the hacker 11 is inserted into the central space S of the slit coil, and a horizontal bar-like suspension part 12 for lifting the slit coil and an upper horizontal part attached with a suspended part 15 suspended by a crane hook (not shown). This is a so-called C-shaped hook having a structure in which the frame 13 and the vertical frame 14 integrally connecting the end portions on one side of the both 12 and 13 form a C shape. The hacker 11 has a structure in which a raising member 17 for raising a part of the upper surface 12a of the rod-like hanging part 12 is detachably attached to the rod-like hanging part 12 of the hacker body 16.

As shown in the perspective view of FIG. 9 (a), pin holes 12b are provided at a plurality of positions spaced in the longitudinal direction of the suspension on the upper surface of the rod-like suspension 12, and a raised member is attached to each pin hole 12b. On the other hand, as shown in FIGS. 9B and 9C, pin holes 17a for fitting the pins 18 are provided on the lower surface of the raising member 17, as shown in FIGS. The raising member 17 is detachably attached to the rod-like suspension portion 12 by fitting the pin 18 on the rod-like suspension portion 12 side into the pin hole 17a. The raising member 17 is provided such that its longitudinal center (center line is indicated by C in FIG. 1 and the like) is located on a vertical line passing through the center of gravity of the hacker in the rod-like suspension portion 12.
In this embodiment, a pin hole 17b is formed in the upper surface of the rod-like suspension part 12, and a pin 19 for preventing coil overturning is detachably inserted into the pin hole 17b. The position of the pin hole 17b is such that the center of the slit coil in the width direction passes through the center of gravity of the hacker when the slit coil is placed on the raising member 17 so that the side surface of the slit coil contacts the pin 19 inserted into the pin hole 17b. It is in such a position.
The upper surface of the rod-like suspension portion 12 is an arc surface, and the upper surface of the raising member 17 is also an arc surface.

The operation | work which lifts the slit coil 1a of the wide end side on the sorting stand 2 using said hacker 11 is demonstrated.
As shown in FIG. 1, the hacker 11 to which the raising member 17 is attached is brought close to the slit coil group G at a height at which the rod-like suspension part 12 is directed to the central space S of the slit coil, and then the hacker 11 is moved forward ( The rod-like suspension part 12 is inserted into the central space S of the slit coil. In this case, the leading end of the raising member 17 does not reach the slit coil 1b adjacent to the slit coil 1a on the end side, and is inserted so as to remain in the region of the slit width of the slit coil 1a on the end side.
Next, in this state, the hacker 11 is raised and the raising member 17 is applied to the inner surface of the slit coil 1a on the end side. FIG. 2 shows the state at this stage.
Next, when the hacker 11 is further raised, only the slit coil 1a on the end side is lifted as shown in FIG. In this case, the elevation of the hacker 11 is limited to a range in which the rod-like suspension portion 12 does not contact the inner surface of the inner slit coil 1b as shown in the figure.
Next, the hacker 11 is retracted horizontally and removed from the central space S of the remaining slit coil group G ′ having a small width, as shown in FIG.
Thus, only the slit coil 1a on the end side can be lifted. The wide slit coil 1a lifted is conveyed to a predetermined place.

  The remaining slit coil group G ′ can be lifted in the same manner as usual by a hacker from which the raising member 17 is removed (that is, the hacker body 5 and the large hacker 5 described with reference to FIG. 10). FIG. 5 shows a state where the bar-like suspension part 12 from which the raising member 17 is removed is inserted into the central space S of the remaining slit coil group G ′. It can be lifted and transported to a predetermined place.

When only the slit coil 1b on the end side of the remaining narrow slit coil group G ′ is lifted, as shown in FIG. 6, the insertion position of the pin 19 for preventing the coil to fall is set to the slit coil 1b. It is also possible to change the position corresponding to the width. In this case, naturally, a pin hole for a coil toppling prevention pin is made at a predetermined position of the raising member 17.
The procedure for lifting the slit coil 1b on the end side is the same as described above.
In this case, the position of the center of gravity of the slit coil 1b to be lifted is deviated from the position of the center of gravity of the hacker 11, so that it is limited to the case where there is no hindrance to lifting even if the center of gravity is shifted.

Further, when only the slit coil 1b on the end side of the remaining narrow slit coil group G ′ is lifted, the raised member is a dedicated short corresponding to the narrow slit coil 1b as shown in FIG. It may be replaced with the raising member 17 ′.
The procedure for lifting the slit coil 1b on the end side by the hacker 11 to which the raising member 17 ′ is attached is the same as described above.
In this case, when the coil fall prevention pin 19 provided on the upper surface of the raising member 17 ′ is applied to the side surface of the slit coil 1b as shown in FIG. 7, the width center of the slit coil 1b passes through the hacker's center of gravity. The position is on the line.

The means for detachably fixing the raising member 17 to the rod-like suspension portion 12 is not limited to the above-described pin holes 12b, 17a and the pins 18, and various means can be employed.
Further, the coil fall prevention means is not limited to the one using the pin hole 17b and the pin 19, and various means can be adopted.
In the above-described embodiment, the case where only one slit coil is lifted by the hacker 11 has been described. However, the present invention is naturally applicable to the case where a plurality of slit coils such as two or three in the slit coil group are lifted.
In the above description, the slit coil group including slit coils having different slit widths has been described as the case of performing the coil hanging work when sorting the slit coils for each slit width. Even when slitting into a plurality of slit coil groups having the same slit width with a slitter, it can be applied when lifting some slit coils (the lifting operation in this case is the same as the case described in FIGS. 6 and 7). ).
Therefore, the coil mount on which the slit coil group is placed is not limited to the sorting table. Further, the present invention is not limited to the case where the slit coil group is placed on the coil mount.

  The shape of the hacker body 5 shown in the drawing of the embodiment is schematically shown, and is not limited to the shape shown in the drawing. In particular, the illustrated suspended portion 15 schematically shows a structure having a hacker posture adjusting function, but may be a simple suspended portion that does not have a hacker posture adjusting function.
