Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spool lamp in which a spool for inserting a tension reel for winding a metal strip is stocked for dispensing to a spool inserting device.

[0002]

2. Description of the Related Art Generally, a cold-rolled thin steel strip is wound on a tension reel and then, when the coil is removed from the reel,
It is well known that the strip on the inner circumference buckles in the inner diameter direction. When the coil wound on the tension reel is buckled in the inner diameter direction by the strip on the inner peripheral portion, the coil may not come off from the reel, or the buckled portion may be damaged such that it is unworthy of a product.

As a measure for preventing the buckling of the coil of the cold-rolled thin steel strip wound on the tension reel, a spool having a wall thickness of about 5 mm or more is inserted into the reel and wound, or an appropriate winding is performed. There is a management of tension, especially the so-called taper tension is adopted, in which the tension of the inner circumference is raised and the tension is gradually lowered to wind up, but generally, the method of inserting the spool into the reel and winding up is often adopted. Has been done. To insert the spool into the tension reel, use a spool insertion device consisting of a spool ramp and a coil car or a carriage for spools, and the spool stocked in the spool ramp is delivered to the spool insertion device, conveyed, and inserted into the tension reel. Is common.

Further, the most preferable width dimension of the spool to be inserted into the tension reel is approximately equal to the width of the winding strip or slightly wider than the width of the winding strip, but it must be prepared in compliance with this. There are many types of spools. Therefore, in practice,
We use spools of several width sizes that are not narrower than the width of the strip to be wound. For example, Table 1 shows an example thereof.

[0005]

[Table 1]

Spool ramps for stocking spools of several kinds of widths as shown in Table 1 above are required to convey spools of several kinds of widths to a dispensing section of a spool insertion device using a coil car or the like. . For this reason,
The spool ramp is provided with a predetermined angle with respect to the horizontal plane, and due to this inclination, the spool rolls on the spool ramp and is conveyed to the dispensing unit. In this case, in order for the spools of various widths to smoothly roll on the spool ramp, as shown in FIG. 4, the spool 12 should not be slanted while rolling on the spool ramp 11 as shown in FIG.
As shown in FIG. 5, it is common to install the guide 13 according to the width of the spool 12.

Further, between the spool carry-in table for receiving the spool from the spool ramp and the spool carry-out table for supplying the spool to the tension reel, the spool is received from the spool carry-in table and the spool is carried out in the spool carry-out table. And a spool storage device for moving a plurality of movable spool receiving devices that can be discharged to the spool between the spool carry-in table and the spool carry-in table, and a desired one of the spool receiving devices is selectively aligned with the spool carry-out table. Spool supply device equipped with a device for moving the spool from the spool receiving device to the spool unloading table (Japanese Patent Publication No. 50-35493).
Gazette), a payout box having an inclined plate for rolling out the stored spool and paying it out, a spool feeding mechanism for feeding one spool paid out from the payout box onto the table, and a length of the spool on the table. A centering mechanism for centering the direction corresponding to the coil winding mandrel, and a swivel arm for gripping the centered spool on the table and swiveling to position it on the axis of the coil winding mandrel are provided. In addition, a movable carriage that is movable on the guide rail along the axial direction of the coil winding mandrel and a movable carriage that moves along the guide rail, and the spool gripped by the swing arm is attached to the coil winding mandrel. A device equipped with a spool insertion drive mechanism (Japanese Patent Laid-Open No. 56-26616), which regularly stores spools. , And easily attached to the spool extractor, a spool boxes removable cartridge type, retrieve the spool from the spool box apparatus provided with a spool transport device for inserting (JP 59-85
No. 320), suction means for the spool in a bag at a predetermined position where the spool is stored upright, transfer means for transferring the spool from the bag by the suction means, and advancing and retracting the suction means between the transfer means and the spool. An advancing / retreating means, and a posture changing means for changing the transferring means from a posture in which the spool is placed upright to a posture in which the spool is placed upside down.
There has been proposed a device (Japanese Utility Model Laid-Open No. 61-110636) in which a transfer means is provided with a gradient so that the spool rolls in a certain direction on a mounting surface on which the spool is mounted in an inverted state.

[0008]

A method of installing a guide according to the width of the spool so that the spool does not become slanted while rolling on the spool ramp is applicable to several types of spools having different widths. Since the guide width is changed each time the spool width is changed, a guide width correction mechanism must be added, which complicates the apparatus itself. Further, the device disclosed in Japanese Patent Publication No. 50-35493 can automatically select several types of spools and insert them into a tension reel, but a spool storage device having a rotation mechanism is installed between a spool ramp and a spool discharge table. The spool ramp cannot directly supply the spool to the spool transport table. Further, the device disclosed in Japanese Patent Laid-Open No. 56-26616 is a dispensing box provided with an inclined plate for rolling the spool to dispense the spool, and the spools having different widths cannot be centered. In order to perform centering, a payout box corresponding to the spool width is required, and there is a disadvantage that the storage space and the operating method of the payout box are complicated. Furthermore, JP-A-59-853
The device disclosed in Japanese Patent Laid-Open No. 20 is characterized in that spools are regularly stored in a cartridge type spool box.
Although different from the device disclosed in Japanese Patent No. 26616, centering of spools having different widths is impossible. The device disclosed in Japanese Utility Model Laid-Open No. 61-110636 is capable of supplying several types of spools having different widths, but suction, transfer, and transfer between the spool insertion device and the bag storing the spool,
It has a drawback that each means of posture change is required.

An object of the present invention is to provide a spool ramp capable of stocking several kinds of spools having different widths in the same spool ramp with their widthwise centers aligned with each other without using side guides.

[0010]

Means for Solving the Problems The inventors of the present invention have made extensive studies to achieve the above object. As a result, the spool ramp cross section in the direction orthogonal to the spool rolling direction has the same stepped center at the center according to the spool width, so that several kinds of different widths can be used in the same spool ramp without using a side guide. The present invention has been reached by the conclusion that spools can be stocked with their widthwise centers aligned.

That is, the present invention relates to a spool lamp in which several kinds of spools having different widths to be inserted into a tension reel for winding a metal strip are sequentially rolled out to a spool insertion device using a coil car or the like and dispensed. The cross section in the direction orthogonal to is formed in a stepped shape with the same center according to several kinds of spool widths.

[0012]

According to the spool ramp of the present invention, the cross section in the direction orthogonal to the spool rolling direction has a stepwise shape with the same center in accordance with several kinds of spool widths. If you center the spool and place it on the spool lamp, you can create a step with a width corresponding to the width of the spool on which the stepped spool lamp is mounted.
The side wall of the staircase spool lamp is used as a side guide to roll and stock in sequence. Therefore, if the dispensing stopper of the spool ramp is released, the stocked spool is sequentially rolled in the steps of the stepped spool ramp having a width corresponding to the width of the spool and dispensed to the spool insertion device.

In the present invention, centering a spool having a predetermined width in accordance with the strip width to be wound according to the rolling schedule and placing it on the spool ramp is not particularly limited, but it is predetermined according to the rolling schedule by manpower or a crane. The spool having the width may be centered and placed, or a mechanism that automates the above operation may be provided. As for the width between the side walls of the stepwise spool ramp in the present invention, if the gap between the rolling end face of the spool and the side wall surface is about 10 mm, the spool rolls smoothly without being inclined. Further, the height of the stairs of the staircase-shaped spool ramp may be empirically at least 20 mm or more. For example, when stocking spools of three types of width, the difference in height of the staircase of the spool ramp is 40 mm or more. However, the payout from the spool lamp to the coil car or the spool-only cart can be carried out practically without any problem.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to FIGS. FIG. 1 is an overall plan view of a spool lamp for winding a metal strip according to the present invention which handles spools of three types of large, medium, and small sizes, FIG. 2 is a side view of FIG. 1, and FIG. 3 is a sectional view taken along the line AA of FIG. Is. 1 to 3, 1 is a tension reel for winding a metal strip, 2 is a spool insertion device such as a coil car for inserting the spool 3 into the tension reel 1 or a carriage for exclusive use of a spool, and 4 is a spool corresponding to the width of the strip to be wound. Spool lamp for stocking 3 and spool lamp 4
The spool 3 placed thereon rolls in sequence toward the spool insertion device 2 side due to the inclination θ of the spool ramp 4.

The spool lamp 4 has a large spool width,
Corresponding to middle and small, the cross section in the direction orthogonal to the rolling direction of the spool 3 has a three-step staircase with the center being the same, and the side wall of the narrowest step 5 and the end surface of the spool 3 having the small spool width are formed. When the distance S is around 10 mm, the spool 3 with a small spool width, and similarly, the spool 3 with a large spool width on the widest step 7
The spool 3 in the spool width is configured to be stocked in the remaining step 6 having the intermediate width. Further, the distances h ₁ and h ₂ between the step-like steps 5, 6 and 7 of the spool ramp 4 are 20
mm.

With the above-described structure, when spools 3 having three different widths are sequentially centered and supplied to the spool ramp 4 in accordance with the width of the strip to be wound, when the spool width is small according to the width of the spool 3. Narrowest step 5
In the case of the medium spool width, it is placed in the step 6 having an intermediate width, and in the case of the large spool width, it is placed in the step 7 having the widest width. Therefore, each spool 3 placed on each stage 5, 6, 7
Due to the inclination θ of the spool ramp 4, the spool ramp 4 is sequentially rolled and stocked on the spool insertion device 2 side. In this case, the gap between the end surface of the spool 3 of each width and the side walls of each step 5, 6, 7 is 10 m.
Since it is configured around m, the spool 3 has each stage 5,
Both side walls of 6 and 7 roll smoothly as side guides and do not tilt.

From spool lamp 4 to spool insertion device 2
When the spool 3 is discharged to the tension reel 1 and the spool 3 is inserted to the tension reel 1, the stopper (not shown) provided at the discharge portion of the spool ramp 4 is released, and the spool 3 having a predetermined width is spooled by the inclination θ of the spool ramp 4. It rolls to the insertion device 2 side and is dispensed onto the spool insertion device 2. The spool 3 dispensed onto the spool insertion device 2 is inserted into the tension reel 1 by moving the spool insertion device 2.
