Description

[Detailed description of the invention] "Industrial application field" This invention is a coil threading device used to feed the tip of the coil mounted on the uncoiler to the leveler feeder in a leveler feeder line that supplies coil material to a press machine. It is related to.

"Prior Art" Conventionally, as shown in Fig. 3, a coil 2 is mounted on a holding stand 1 of a coil car and mounted on a drum 3 of an uncoiler, and after lowering the retainer 1 slightly, the tip of the coil 2 is placed on a holding stand 1. 1, the tip of the blade 5 of the opener 4 is fed out to below the blade roll 6, and as shown in FIG. was bent, and the coil 2 was further fed out several times little by little and guided to a leveler feeder (not shown) while being bent.

``Problem that the invention aims to solve'' In the conventional device described above, the operator visually determines the degree of bending of the tip of the coil, so if the operator is inexperienced, the coil may be bent too much or not enough. ,
The disadvantage was that a lot of time was wasted guiding the tip of the coil to the leveler feeder.

An object of the present invention is to eliminate this drawback and to provide a coil threading device that can extremely easily guide the tip of the coil to the leveler feeder regardless of the skill level of the operator.

"Means and effects for solving the problem" The configuration of the present invention is that an opener is provided with the leveler feeder side pivoted to a frame and swings up and down toward the coil mounted on the uncoiler in a coil car. A blade roll that rotates freely is provided at the tip of the telescopic blade, and an arm that is shorter than the opener is installed below the opener, and the leveler feeder side is pivoted to a frame and swings up and down. A driven guide table roll is provided below the opener, and the leveler feeder side is pivotally mounted on a pedestal, and the tip engages a connecting plate that connects the ends of the arms, and the guide table swings together with the swing of the arm. It is characterized by having been established. After the tip of the coil is held between the blade roll of the opener and the guide table of the arm, the guide table roll is rotated in conjunction with the uncoiler drum, and the coil is continuously bent by the rotation of the guide table roll. The tip of the coil is guided between the upper and lower pinch rolls of the leveler feeder while being guided from above and below.

Embodiment FIGS. 1 and 2 show the structure of a coil threading device 7 of the present invention installed in a coil feeder line. Holding stand 9 of coil car 8
The coil 10 is placed on the uncoiler drum 11 by running the coil car 8 from the front in the figure.
The coil feeder line has an uncoiler (not shown),
It consists of a threading device 7 and a leveler feeder 12, and the coil 10 is fed out and fed to a press (not shown). Frame 1 of threading device 7
3 is provided with an opener 14 whose one end is pivotally connected at a required height on the leveler feeder 12 side. The opener 14 has a blade roll 15 which is rotatable at its tip and has a required length in the direction perpendicular to the paper surface of the figure.
A blade 16 provided with a blade 16 is provided to be extendable and retractable, and is expanded and contracted by a cylinder 17. The upper center of the length of the opener 14 is connected to the piston rod of a downward cylinder 18 which is pivoted to the frame 13 above it, and the opener 14 can swing between the solid line and the dashed line as the cylinder 18 expands and contracts. It is becoming.

At the lower center of the length of the opener 14, one end of the coil 10 is pivoted to the frame 13 on both sides of the sent coil 10, and one arm 19, 19 is provided that can swing in correspondence with the blade roll 15 of the opener 14. (shown in front of the paper in FIG. 1) is provided, and a guide table roll 20 is provided between the ends of the arm 19, which is rotated clockwise in FIG. 1 by a hydraulic motor 20B via a cam clutch 20A. Cylinders 22 are provided between the lower surfaces of both sides of the connecting plate 21 that connects the tips of the arms 19, 19 and the lower part of the pedestal 13, and the expansion and contraction of the cylinders 22 causes the arms 19, 19 to move between the solid lines and the dashed line. It is now possible to swing. Below the opener 14 is a guide table 23 whose one end is pivotally connected to the pedestal 13 on the leveler feeder 12 side and whose other end extends in the direction of the coil 10 and engages on the connecting plate 21.
has been established. The guide table 23 has a sufficient width to receive and guide the lower surface of the sent coil 10, and has a large number of guide rolls 24 on its upper surface, which are long in the width direction and arranged in parallel in the length direction. The guide table 23 swings together with the swing of the arm 19.

The leveler feeder 12 is provided with a pair of pinch rolls 25 that can pinch the coil 10 fed from the inlet side from above and below, followed by a work roll and a feed roll (not shown). Level feeder 1
2 entrance, opener 14 and guide table 23
The upper guide 26 and the lower guide 2 are connected to the pivot joint of the
7 and a side guide 28 are provided to guide the tip of the coil 10 fed between the opener 14 and the guide table 23 to the pinch roll 25.

Regarding the operation, the coil 10 placed on the holding stand 9 of the coil car 8 is moved to the drum 11 of the uncoiler.
After the coil 10 is mounted on the coil 10, the holding table 9 is lowered slightly, and the tip of the coil 10 is let out below the blade roll 15 of the opener 14 shown in the figure. Extend the cylinder 18 and swing the opener 14 downward, and the blade roll 1
5 to position the tip of the coil 10 and move it to the cylinder 22.
Stretch out the tip of the coil 10 and roll it into a blade roll 15.
and the guide roll 20. The drum 11 of the uncoiler and the guide table roll 20 are driven in conjunction, and the coil 10 fed out from the drum 11 is continuously bent by the opener roll 15 and drawn between the opener 14 and the guide table 23, and the pinch roll of the leveler feeder 12 is driven. Leads to 25. When the coil 10 is inserted into the leveler feeder 12, the cylinder 22 is retracted to move the coil car 8 backward in the direction of the paper surface of the drawing, and the guide table 2
3 is swung downward to operate the coil feeder line in conjunction with the press. At this time, the guide table roll 20 idles clockwise and guides the coil 10 by the action of the cam clutch even if the hydraulic motor is stopped.

"Effects of the Invention" As is clear from the above explanation, according to the present invention, a guide table having a guide table roll that cooperates with the blade roll of the opener to drive the coil is provided, so that the tip of the coil is connected to the blade roll and the guide table roll. The practical effects and advantages are that just by holding it between the table rolls, the subsequent work can be done almost automatically, no skill is required for the work, and work time can be shortened. big.
