DETAILED DESCRIPTION OF THE INVENTION
[Example]
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
First, the apparatus configuration will be described.
1 to 3, reference numeral 9 denotes an attachment comprising four arc-shaped segments having racking 12 formed on both sides, and 10 denotes an outer diameter expansion / contraction reel inserted into the attachment 9. FIG. 3 shows an outer diameter expanding / contracting reel 10 that has been reduced (fully closed) to a diameter, and FIG. 3 shows an outer diameter expanding / reducing reel 10 that has been expanded (fully opened) to a maximum outer diameter. Reference numeral 11 denotes a drum in which a stopper 13 is arranged on the inner periphery so that the inner diameter of the attachment 9 is larger than the minimum outer diameter of the expansion / contraction reel 10 and can be held at an inner diameter smaller than the maximum outer diameter. Specifically, three rings having four diameter holding stoppers 13 arranged in the circumferential direction have a gap, and a stopper wrestling ring is arranged between the stopper deploying rings, and these are joined in a drum shape with a frame. Constitute.
[0012]
Reference numeral 14 denotes a drum mounting base on which the inner diameter holding stopper drum 11 is rotatably mounted via a roller 24. A coil spring 15 supports the diameter holding stopper drum 11 and the mounting table 14 on the apparatus base 17 so as to be movable up and down. Reference numeral 16 denotes an elevating guide provided on the device base 17 of the drum mounting base 14. Reference numeral 20 denotes a rotational position adjustment mechanism comprising a rack provided on the outer surface side of the drum 11 and a gear provided on the lifting platform 14 side, and enables fine adjustment of the alignment of the reel base, the radial of the attachment, and the thrust stopper 22. Reference numeral 21 denotes a coil car on which the apparatus base 17 is mounted. Reference numeral 25 denotes an upper and lower limit stopper for the drum mounting table 14 provided on the lifting guide 16. When the upper surface of the drum mounting table 14 comes into contact, the inner diameter holding stopper drum core 26 matches the expansion / contraction reel core 27 as shown in FIG. ing.
[0013]
The tip 13 of the stopper 13 has a claw shape as shown in FIG. 4, and the claw-shaped diameter holding stopper 13 can be swung in the axial direction of the attachment 9 and can be pivoted to the axis of the attachment by a torsion spring 23. The drum 11 is provided so as to return its posture in the orthogonal direction. The thickness of the stopper 13 corresponds to a gap formed between the segments of the attachment whose diameter is held by a conventional saber-like stopper.
[0014]
Reference numeral 18 denotes a cradle for receiving both ends of the attachment 9 which is held by holding the stopper 13 of the inner diameter holding stopper drum 11 outside the outer periphery of the attachment between the segments. The attachment receiving surface is composed of a plurality of rollers 19. It is provided on the base 17.
[0015]
As shown in FIG. 1, the height of the receiving surface of the cradle 18 is reduced to the minimum outer diameter by placing the core 26 of the attachment 9 eccentrically below the core 27 of the reel 10 by a slight distance x. There is a slight gap y between the upper surface of the reel 10 which is fully closed and the inner peripheral upper surface of the attachment having the above-mentioned diameter, and it can be inserted into the reel 10 which has been reduced to the minimum outer diameter (fully closed), as shown in FIG. Thus, after inserting into the reel 10 that has been reduced to the minimum outer diameter (fully closed), the reel outer diameter is enlarged, the attachment core matches the reel core, and the reel outer diameter reaches the maximum outer diameter (fully open). 10 is set so that there is a gap z between the outer peripheral lower surface of the attachment 9 fixed to 10. Specifically, the height of the attachment receiving surface of the attachment receiving base 18 is set so that the gaps y and z and the distance x satisfy the relationship x = y = z.
[0016]
The coil spring 15 is compressed when the load of the attachment 9 is applied to the drum mounting table 14 via the stopper 13, the drum 11 and the roller 24 as shown in FIG. However, as shown in FIG. 3, when the load of the attachment 9 is unloaded, the coil spring 15 is extended so that the upper surface of the drum mounting base 14 is brought into contact with the upper and lower limit stopper 25 is selected. ing.
[0017]
Next, a method for attaching an attachment to a reel using the above apparatus will be described. As shown in FIG. 1, the device (base 17) and the attachment 9 are mounted on the coil car 21. At that time, the diameter of the attachment 9 is held by a claw-shaped stopper 13 inserted between the segments, and the attachment 9 is mounted on an attachment base 18 on the apparatus base 17. At that time, the load of the attachment 9 acts on the mounting base 14 via the claw-shaped stopper 13 and the drum 11, and the coil spring 15 is compressed. That is, the mounting base 14 is in the lowered position, and the axis of the attachment 9 is at a position lower than the reel axis.
[0018]
When inserting the attachment into the reel whose rotation has been stopped at a substantially fixed position, it is necessary to align the radial stopper for positioning with the thrust stopper 22, and the rotation adjusting mechanism 20 rotates the attachment 9 together with the drum 11 for fine adjustment. Do. At that time, the attachment can be rotated with little sliding resistance by the roller 19 on the surface of the cradle 18.
[0019]
From the state of FIG. 2 after fine adjustment, the coil car 21 is run and the attachment 9 mounted on the apparatus is inserted into the reel. At this time, the thickness of the claw-like stopper 13 that determines the height of the attachment receiving base 19 and the attachment holding diameter is determined so that there is no interference between the upper surface of the reel in the reduced state and the upper surface of the inner periphery of the attachment. After the insertion is completed and it is confirmed that the radial stopper and the thrust stopper 22 at the reel base are aligned, the reel is enlarged. First, the attachment is lifted on the upper surface of the reel that expands while maintaining the diameter, and is lifted from the cradle 18 at the same time. At this moment, the coil spring 15 extends while the attachment load is unloaded and the attachment rises.
[0020]
That is, the claw-shaped stopper 13 rises together with the drum 11 and the attachment, and the positional relationship between the segment gap and the claw-shaped stopper 13 is maintained. Further, the reel outer diameter becomes the same as the retained inner diameter of the attachment during expansion, and the attachment shaft core and the reel shaft core are matched for the first time. At this time, the drum mounting base 14 is in the ascending position (position where it abuts against the ascending stopper 25), and the ascending is not necessary. When the attachment is further expanded from there, a gap is formed between the claw-shaped stopper 13 and the segment, and the claw-shaped stopper 13 can swing.
[0021]
Next, the empty device is retracted. The claw-like stopper 13 that can swing is able to get over even if the gap between the segments is racked, and is pulled out together with the retracted device. When the device is retracted, the height of the attachment cradle 18 is determined so that the enlarged lower surface of the outer periphery of the attachment does not interfere with the attachment cradle. That is, the height of the cradle that can avoid both interference with the reel when inserting the attachment and interference with the cradle when the empty device is retracted is satisfied using the change in the height of the shaft core. Has been determined.
Thus, the attachment is inserted into the reel and fixed.
[0022]
Next, an operation for removing the attachment from the reel will be described.
An empty device is mounted on the coil car, and first, fine adjustment is performed by rotating the drum by the rotation mechanism 20 so that the segment gap of the attachment is aligned with the position of the claw-shaped stopper 13.
[0023]
When the device is inserted while running on the coil car 21, the claw-shaped stopper 13 can get over even if the segment gap is racked, and is inserted into the attachment together with the device, resulting in the state shown in FIG. Next, when the reel is fully closed, the attachment 9 shrinks with the same core height until the nail-shaped stopper is pinched, and after the attachment diameter holding state is formed, the lower surface of the reel to be lowered lowers the attachment. Finally, it will be mounted on the cradle. Further, the reel shrinks and finally a gap is formed between the reel outer peripheral upper surface and the attachment inner peripheral upper surface, and the attachment is separated from the reel. Finally, the coil car equipped with the attachment travels and retreats to complete the work.
[0024]
As described above, in this embodiment, the claw-like stopper 13 is returned to the swinging posture by the torsion spring 23 in order to reduce the drive source and reduce the cost of the apparatus and shorten the work time. The elevator 14 of the drum-like stopper mounting drum 11 is supported by a coil spring 15, and the height of the attachment receiving base 17 is fixed so that the attachment can be received and released. The attachment 9 can be attached / removed only by an inevitable operation such as an expansion / contraction operation. The adoption of the claw-shaped diameter holding stopper that can swing and return the posture eliminates the need for saber groove processing, and has the effect of facilitating attachment manufacturing.
[0025]
This embodiment is suitable for attaching and detaching an attachment consisting of arc-shaped segments with racking formed on both sides, but it may be an attachment in which both sides of the segment are straight without providing racking. In this embodiment, it can be attached to and detached from the reel. When only the latter attachment is handled, the diameter holding stopper may be fixed to the diameter holding stopper drum.
[0026]
Further, in this embodiment, the claw-shaped diameter holding stopper is provided on the diameter holding stopper drum so as to be able to swing in the axial direction of the attachment and to return its posture in a direction perpendicular to the axis of the attachment by a torsion spring. However, the diameter holding stopper drum is provided with a diameter holding stopper that can be moved forward and backward in the direction of the diameter holding stopper drum by an electric cylinder mechanism, for example, and a power source for the electric cylinder mechanism such as a battery, an operation panel of the electric cylinder mechanism, etc. A drive source may be mounted on the apparatus, and the diameter holding stopper may be inserted / removed between segments from the outer periphery of the attachment.
[0027]
Furthermore, in this embodiment, a rotation mechanism is provided as a fine adjustment mechanism for positioning the reel base and the attachment radial stopper and thrust stopper. However, the reel base always has the same position because the rotation stop accuracy of the reel is improved. This rotation mechanism is not necessary if the fixed condition is ensured.
[0028]
【The invention's effect】
As described above, according to the apparatus of the present invention, it is possible to eliminate the insertion and extraction of the saber-like stopper plate, which has been conventionally required when attaching and removing (attaching and removing) the reel attachment. There is no need for the configuration, and there is an advantage that the attachment for changing the reel diameter can be attached and detached by utilizing the inevitable operations such as the running of the coil car and the expansion / contraction operation of the reels.
