Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a spritzer bar device used in a slitter winder or the like.

[Prior Art] For example, in a slitter winder a as shown in FIG.
A wide paper web d unwound from the slitter unit e is cut into a predetermined width, wound onto a core h placed on a rear drum f and a front drum g, and a required pressing pressure is applied by a rider roll i. The winding roll j is obtained by applying the

The paper web d' that has just been cut by the slitter unit e has only a cut in the longitudinal direction, and if it is wound up in that state, the cut ends will interfere with each other and the product will be damaged.

Therefore, in the past, a spret dar bar k was disposed on the entrance side of the rear drum f over the entire width of the paper web d', and, for example, as shown in FIG. The spreader bar k is bent to form a convex curved surface by adjusting the protruding length of each screw rod m, and the interval between the cut paper webs d' is slightly widened by the convex curved surface at the top.

Also, Figures 5 to 7 of Japanese Patent Publication No. 44-23884
As shown in the figure, a segmented and connected roll-type arcuate deployer configured like a single roll by attaching a plurality of short rolls adjacent at their ends to bearings supported on a bendable shaft. is also known, and in the case of this spreader bar, it is also bent to form a convex curved surface in the same way as the above-mentioned spreader bar k, and the interval between the cut paper webs is widened by the convex curved surface at the top.

[Problems to be solved by the invention] However, when the above-mentioned spretz darbar k is used, the spritzer bar k always remains on the paper web.
Since it is in contact with d', it takes time to replace and adjust it due to wear due to friction and changes in the slitting operation. During this time, the operation of the slitter winder a had to be stopped, which caused a problem in that the operating rate of the slitter winder a decreased.

Further, when a split and connected roll type arcuate expander is used, since the rolls are divided, there is a problem in that paper is likely to get caught in the gaps between the rolls, causing paper breakage. In particular, the tension of the paper is low when passing the paper.
Thin paper or the like could easily fold due to slight wind pressure, and the paper could easily get caught in the gap between the rolls.

Furthermore, in this kind of roll-type arcuate expander, during operation, the tension of the paper is distributed in the width direction in accordance with the curved shape of the roll, with the center part receiving strong pressure and the width end part receiving weak pressure. The rotational force applied to the roll is different between the two, and there is a risk of damage to the paper web due to the edges of the roll that do not rotate.

[Means for Solving the Problems] The present invention aims to solve the above-mentioned conventional problems, and includes a support frame having a substantially full width in the vicinity of the seat travel path, and extending in the width direction of the seat. A plurality of holding members are arranged to be rotatable about an extending axis and set in positions at at least two locations in the rotational direction, and a plurality of holding members are disposed through the support frame so that their protruding lengths can be adjusted from at least two directions; This invention relates to a spreader bar device characterized in that a spreader bar is removably attached to the tip of each holding member penetrating in each direction.

[Function] While the spreader bar supported by each holding member in one direction is in use, the spreader bar is attached to each holding member in the other direction to perform presetting such as adjustment of the convex curved surface, and to rotate the support frame by the required angle when replacing it. Therefore, replacement can be easily and quickly performed by moving the preset spreader bar to the use position.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

Figures 1 to 3 show an embodiment of the spreader bar device of the present invention, in which a sheet 4 such as a web of paper is made to travel at a position downstream of the slitter unit 1 and upstream of the take-up drum 2. A support frame 5 having substantially the same length as the width of the seat 4 is disposed near the seat travel path 3 in the width direction of the seat 4, and both ends of the support frame 5 are supported by support stands 6 in the width direction of the seat 4. It is rotatably supported around an axis extending in the .

Further, a plurality of threaded rods 7 as holding members are threaded through the support frame 5 so as to be perpendicular to each other from one direction at a required interval, and a threaded rod having a length approximately the same as the width of the sheet 4 is attached to the tip of each threaded rod 7. The spreader bar 8 is removably attached, and a plurality of threaded rods 7' are threaded through the support frame 5 so as not to interfere with each of the threaded rods 7 at a required interval from a direction different from the above direction so as to be perpendicular to the support frame 5. Similarly, a spreader bar 8' is removably attached to the tip of each threaded rod 7'.
Here, the angle of each threaded rod 7, 7' in the two directions is:
It is sufficient that the angle of the other spret dar bar 8' and threaded rod 7' does not interfere with the seat 4 when one spret dagger bar 8 is in use, and that it does not hinder the replacement work of the spret daver bar 8'.
120° is sufficient.

A lever 11 having a handle 10 is fixed to the end of one shaft 9 of the support frame 5, a protrusion 12 is provided on the inside of the lever 11, and the protrusion 12 is provided in each hole 13 provided on the side surface of the support stand 6. By fitting the springs 12, the support frame 5 can be fixed in the use position of each spreader bar 8, 8'.

With the above structure, the protrusion length of each threaded rod 7 in one direction is adjusted respectively to make the convex curved shape of the spreader bar 8 into a desired shape, and the handle 1
0, the support frame 5 is rotated by turning the lever 11, and when the spreader bar 8 is in the use position, the protrusion 12 is fitted into the hole 13 of the support stand 6, and is positioned and fixed.

This makes it possible to operate the slitter winder by attaching or replacing the spret dar bar 8' to each threaded rod 7' provided in the other direction and adjusting the protruding length of each threaded rod 7'. A convex curved shape of the spreader bar 8' can be set.

When replacing the spretsider bar 8 in use, the line is stopped, the lever 11 and the support frame 5 are rotated by a predetermined angle using the handle 10, and when the new spretsider bar 8' is in the use position, the rotation is stopped. Therefore, the spreader bars 8, 8' can be replaced quickly and reliably, and the downtime of the line can be greatly reduced.

In addition, since the above-described spret darbar device of the present invention uses the integrated spret darbar 8, there is a possibility that paper may get caught in the gap between the rolls, such as in the split-connected-roll type arcuate expander described above. There are no defects and there is no risk of damage to the paper web due to the edges of the non-rotating roll.

It should be noted that the spreader bar device of the present invention is not limited to the above-described embodiments, and may include three or more spreader bars, and other means may be used for the rotation and locking mechanism of the support frame. Of course, various modifications can be made without departing from the gist of the present invention, such as that the holding member is not limited to a threaded rod and that it can also be applied to a two-shaft winding type.

[Effects of the invention] As described above, the spret darbar device of the present invention is provided with a plurality of spret darbars and is constructed so that the whole can be rotated and fixed, so that it is possible to preset the next spret darbar during the winding operation. It is possible to easily and quickly perform tasks such as replacing the spretzer bar that has worn out during winding work or adjusting the spretzer bar to change the winding conditions, and as a result the winding preparation time is greatly reduced. Various excellent effects can be achieved, such as a marked improvement in the operating rate of the system.
