Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a threading guide device in roll equipment for threading a metal plate such as a strip onto a large size roll such as a bridle roll.

[Conventional technology]

Conventionally, in bridle roll equipment, a guide plate made of a pressing roll and a flat plate is provided around the bridle roll so as to face the roll surface, and between the guide plate and the roll surface is driven by the bridle roll and the pressing roll. The strip was passed through, and it was assumed that the strip had rigidity.

[Problems to be solved by the device]

In recent years, the demand for thin plates has increased, and it has become impossible to secure the necessary rigidity due to the progress of thinning of strips to be threaded. Due to the lack of rigidity, in the conventional threading guide device,
During the passage between the roll surface and the guide plate, the tip of the thin strip bends due to its own weight buckling, and it is pushed by the succeeding strips that are fed sequentially and easily folds and becomes crumpled, and also causes clogging. It was However, since the bridle roll equipment itself has a wide range of application of the material to be threaded, from thin sheet to thick sheet, the equipment cannot be downsized due to the thin strip. For this reason, conventionally, in the case of a thin strip, there are many cases in which the operator has to put his hand on the strip tip so that the tip of the strip does not buckle under its own weight.
It was a safety issue.

[Purpose of device]

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to make it possible to reliably guide a threaded plate at the leading end of a metal plate regardless of whether it is a thick plate or a thin plate in the same equipment.

[Means for Solving the Problems]

The plate passing guide device in the roll equipment of the present invention is such that, in the roll equipment, a metal plate is wrapped around a roll to face the roll surface so that the metal plate can pass through, and a pressing roll and a guide mounting frame are provided. The end is pivotally attached to the fixed frame of the roll equipment, and the other end is provided so as to be movable back and forth toward the roll surface, and is rotated in the metal plate guide direction on the metal plate guide surface of the guide mounting frame. The present invention is characterized in that a metal plate guide mechanism having a possible rotation guide is provided, and the object is achieved by such a configuration.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is a plurality of bridle rolls (4 in the embodiment)
Then, the metal plate 2 transferred on the material pass line is passed.

Reference numerals 3, 4, 5, 6, and 7 denote guide plates, which are fixed to the fixed frame 8 of the bridle roll equipment and are arranged along the threading line of the equipment.

Reference numerals 9, 10, 11, and 12 denote guide mounting frames, which are arranged alternately with the guide plates 3, 4, 5, 6, and 7 along the threading line of the bridle roll equipment. One end (entrance side end or exit side end) of each of 11, 11, 12 is pivotally attached to the fixed frame 8 by a pin 14 via a bracket 13.

Reference numeral 15 is one or a plurality of front-rear moving cylinders (air cylinders or the like), one end of which is attached to the fixed frame 8 by a bracket 16
Is pivotally attached by a pin 17 via a pin, and the other end is rotatably attached to the other end (outlet side end or inlet side end) of the guide mounting frame 9, 10, 11, 12 via a pin 18. It is connected.

Reference numeral 19 denotes a guide plate, which is the guide mounting frame 9,
Each of 10, 11, 12 is provided so as to form a metal plate guide surface, and a plurality of roller mounting holes 20 are formed in the guide plate 19 substantially uniformly by staggered arrangement or the like. Reference numeral 21 denotes a plurality of small-diameter rollers, which are rotatably mounted on the guide mounting frames 9, 10, 11, 12 by brackets 23 via brackets 22 and arranged in the roller mounting holes 20 of the respective guide plates 19. It projects from the plate guide surface to the bridle roll 1 side.
Although the guide plate 19 is provided with a small-diameter roller 21 as a rotation guide that is rotatable in the metal plate guide direction, as shown in FIG.
It goes without saying that a belt-type metal plate guide mechanism in which 5 is rotatably mounted and a belt 26 is hung between the rolls 24 and 25 may be used.

A pressing roll 27 is rotatably attached to the fixed frame 8 and is arranged in front of the entrance of the plate guide device of the bridle roll facility, at a required position in the middle part, and after the exit.

In the present embodiment, an example in which the forward / backward movement cylinder 15 is used to press the metal plate 2 against the bridle roll 1 by the small diameter roller 21 or the belt 26 has been described, but the same operation can be performed by using a manual cam mechanism or the like. It is effective.

[Action]

When the metal plate 2 is a thick plate, the bridging roll 1 and the guide plates 3, 4, 6, 7 are provided between the bridle roll 1 and the guide plate 19 and the small-diameter roller 21 (or the belt 26) by the forward-backward movement cylinder 15. And the guide plates 3, 4, while maintaining substantially the same clearance between
If it is used as a fixed guide similar to 6, 7, the metal plate 2
After entering the bridle roll equipment from above the material pass line by the driven bridle roll 1 and presser roll 27, the guide plates 3, 4, 5, 6, 7 and the guide mounting frames 9, 10, 11, 12 respectively While being alternately guided by the guide plate 19 and the small diameter roller 21 (or the belt 26) provided in the above, the plate is passed through the bridle roll facility. In addition, the rod mounting operation of the forward / backward movement cylinder 15 causes the guide attachment frames 9, 10, 11 and 12 to move around the pivot pin 14 with the fixed frame 8 as a center.
If the small diameter roller 21 (or the belt 26) is brought into contact with the bridle roll 1 with a small clearance by rotating it to the side, and the pressing force is biased by the forward / backward movement cylinder 15, the tip of the metal plate 2 Is a guide plate 19
It slides on top and is guided to the small diameter roller 21.
And the bridle roll 1 are sandwiched between them and the moving force is applied, and this operation is performed one after another (or the sandwiching between the belt 26 and the bridle roll 1 is continuously applied to the moving force. ), Even when the metal plate 2 is a thin plate having insufficient rigidity, the metal plate 2 is passed through the bridle roll facility like the thick plate, and the tip of the metal plate 2 does not become crunchy. Also, it will not be clogged in the equipment.

[Effect of device]

As described above, in the present invention, a part of the threading guide is pivotally attached to one end (entrance side end or exit side end) and the other end (outlet side end or entrance side end). ) Is movable so that it can move back and forth with respect to the roll surface, and a metal plate guide mechanism having a rotation guide that can rotate in the metal plate guide direction is provided on the metal plate guide surface, and the metal plate is moved by the rotation guide. By pressing it against the roll surface, it is possible to reliably guide the passage of the tip of the metal plate even with a thin plate. Further, if the movable plate guide is arranged as a fixed guide with a predetermined clearance from the roll surface, the plate guide of the leading end of the metal plate can be reliably performed even with a thick plate. Therefore, it is possible to handle the thin plate without trouble in the equipment applied to the thick plate, and it is possible to sufficiently deal with various plate thicknesses.
