Description

[Detailed description of the invention] The present invention relates to a slitter, that is, a device for continuously longitudinally cutting a traveling sheet-like object to obtain a plurality of narrow width sheet-like objects, and particularly relates to the winding section of the slitter. The present invention relates to the structure of a core breaking device provided.

In general, sheet-like materials (a general term for thin sheets such as films and metal foils) are wound up using a winding machine that is directly connected to the sheet manufacturing process, and then the winding roll is rewound as necessary.
The sheet is vertically cut to the desired width and re-rolled, but this method requires two steps to obtain the final narrow-width roll product and is inefficient. A so-called in-line slitter winder is used, which winds the material into rolls.

In this case, a number of cores (mainly paper tubes) are supplied to the winder according to the width of the product and the number of cuts, but handling these cores is not easy, especially from supplying the cores to taking them out. If automation is attempted, the problem is inevitable that a core magazine, a core supply device, and a core take-out device are required, and that there are many mechanisms related to the winder, each of which has a complicated structure.

The present invention has been developed in response to such circumstances, and its main purpose is to promote automation by simplifying the structure of the winding device immediately after the slitter.

Therefore, in the present invention, the winding core is made into an integral structure that can be easily broken in advance, and after each sheet-like material after in-line slitting is simultaneously wound around the winding core, the winding core is broken off. The method is characterized in that it attempts to obtain a plurality of product rolls, and for this purpose, each product roll of the vertical rolls, in which the product rolls are integrally formed in vertical rows on the breakable core, is divided into parts. a plurality of roll receivers arranged in a horizontal line in a horizontal coaxial manner corresponding to each winding portion of the core, and above a first roll receiver at one end of the roll receivers; and a roll holding mechanism disposed at an adjacent second roll receiver and movable up and down to bring a presser member at the working end into contact with and away from the first roll receiver; They are placed on the roll receiving side and on the opposite side, respectively.
A first push-up mechanism and a second push-up mechanism in which each push-up member at the operating end can be moved up and down across the second roll receiver, a product roll holding operation by lowering the presser member, and a second push-up mechanism. Column roll bending operation by vertical movement of the push-up member of the push-up mechanism, first
and a control means for sequentially performing the vertical roll bending operation in the opposite direction by the lifting and lowering movement of the pushing-up member of the pushing-up mechanism,
By bending the winding core of the vertical rolls in two symmetrical directions at the creases, it becomes possible to separate the product rolls, and in combination with the simultaneous winding means, the slitter post-processing process can be simplified. The goal was now achieved.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The examples shown in FIGS. 1 to 5 are examples of the device of the present invention in which the winding core is separated into two, but even if the winding core is to be cut into a large number of cores, no separating means is required. What is necessary is to add a conveying device that moves the fold of the winding core to the separating position.

In the figure, reference numeral 1 denotes a vertical roll, which has a serial structure and can be separated by folding at the required number of creases 4 (one in the illustrated example) that are pre-applied around the outer circumference of the core (hereinafter referred to as By winding a sheet-like material running in parallel through a slitter (not shown) on each winding part of the winding core 2, the fold 4 is sandwiched between each winding core 2. Product roll 3-
₁ , _3-2 are integrally formed in a column.

The fold 4 can be easily formed by making a cut around the outer periphery of the winding core 2, which is a round cylinder, so that a thin part remains in the inner layer.The winding core 2 is generally made of a paper tube. Therefore, it is an extremely easy means to make such cuts.

_5-1 and _5-2 are roll holders, each of which has a horizontal support corresponding to each winding part of the winding core 2 so that each product roll _3-1 , _3-2 of the vertical roll 1 can be supported in a shared manner. The roll receivers _5-1 and 5-2 are arranged in a coaxial horizontal line, and are spaced appropriately so that the roll receivers 5-1 and _5-2 can horizontally support the product rolls _3-1 and _3-2 from below near their respective ends. Two pedestals placed side by side _5-1
A , _5-1A , _5-2A , _5-2A , and one end, for example, the right end roll receiver in FIG.
It is called a roll receiver _5-1 , and two roll receivers _5-2 , etc. are called successively to the left.

above the first roll receiver 5-1 and the second roll receiver _5-1 ;
A roll holding mechanism 6 is provided at a position closer to the roll receiver _5-2 , while a roll holding mechanism 6 is provided below the second roll receiver _5-2 at a position closer to the first roll receiver _5-1 and a position closer to the opposite side thereof. The first push-up mechanism _7-1
and a second push-up mechanism _7-2 are provided, respectively.

The roll holding mechanism 6 is equipped with a presser member 8 at the lowermost part, which is the operating end, which has a shape that allows surface contact with the outer periphery of the product rolls _3-1 and _3-2 in the vertical rolls 1. 1 roll receiver _5-1
In the illustrated example, an air cylinder is used to dispose the rod downward, and the presser member 8 is attached to the rod end of the rod.

On the other hand, the first push-up mechanism _7-1 and the second push-up mechanism _7-2 have the same structure as the roll holding mechanism 6, and each push-up member _9-1 corresponds to the presser member 8. , _9-2 at the top, which is the operating end, and the push-up members _9-1 , _9-2 are provided so as to be movable up and down across the second roll receiver _5-2 . The illustrated example has a structure in which an air cylinder is disposed upward, and push-up members _9-1 and _9-2 are respectively attached to the rod ends of the air cylinder. It is something to do.

Note that 10 in FIGS. 3 and 4 is a drive for rotating the first roll receiver _5-1 and the second roll receiver _5-2 in order to release the product roll _3-1 and product roll _3-2 . As shown _by broken _lines in _FIG .
_5-2A can be rotated and tilted by about 45 degrees from the horizontal position.

In addition, in Figures 1 and 2, 11 is a gangplank;
Reference numeral 12 indicates roller conveyors for transporting the product rolls _3-1 and _3-2 , respectively.

Next, the folding operation by the core folding device having the structure described above will be explained. The vertical roll 1, in which the product rolls _3-1 and _3-2 are integrally formed in a vertical line, is moved to the first roll receiver 5-. ₁ and product roll _3-1 is the second
With the product rolls _3-2 placed on both roll receivers _5-1 and _5-2 so that the product rolls _3-2 are supported by the roll receivers 5-2, first, as shown in FIG. is activated to lower the presser member 8,
The left end portion of the product roll _3-1 is held by the first roll receiver _5-1 .

Next, operate the second push-up mechanism _7-2 ,
Product roll _3-2 is lifted by the lifting member _9-2 .
Push up the part near the left edge.

As a result of the bending moment acting on the core 2 of the vertical rolls 1, most of the core 2 of the vertical rolls 1 is broken off at the crease 4, but the upper part remains slightly unbroken. Following the return of the second push-up mechanism _7-2 to its original position, the first push-up mechanism 7-2
₁ is activated to move the push-up member _9-1 up and down (see Figure 4), a bending moment that is completely opposite to that in the previous case acts on the winding core 2, and as a result, the winding core 2 remains unseparated. The portion of the upper fold line 4 that was being held is cut off, and the product rolls _3-1 and _3-2 are completely separated from the fold line 4.

The separated product rolls _3-1 and _3-2 actuate the drive device 10 to send the product roll _3-1 on the first roll receiver _5-1 to the roller conveyor 12 via the gangplank 1.

After this product roll _3-1 is moved to a predetermined center position by the centering device 13 installed on the roller conveyor 12, the roller conveyor 1 is moved as shown in the second figure.
2 is tilted to send the product roll ( _3-1 ) to the next processing step, such as a packaging step.

In the same manner, the product roll _3-2 is also attached to the gangplank 11.
After being sent to the roller conveyor 12 through the centering device 13 and moved to the center by the centering device 13, the roller conveyor 12 is tilted to send it to the next processing step, completing the series of separation operations.

In addition, the centering device 13 is as shown in FIG.
A pair of double-rod type air cylinders 14, which can be slid left and right by rotation of the handle 6, are arranged symmetrically side by side, and an arm 1 is attached to the cylinder body side, which serves as a moving member.
The arms 15, 5 are supported and fixed so as to face each other, and the air cylinders 14, 14 are operated to move the arms 15,
By moving 15, the product roll can be easily moved to the central position.

The apparatus described above based on the drawings is adapted to the tandem roll 1 having two product rolls _3-1 , _3-2 , but it can also be used with three or more product rolls _3-1 , _3-2 , 3. - Column roll 1 with ₃ ...
To accommodate this, the same number of roll receivers _5-1 , _5-2 , _5-3 , etc. as the product rolls are arranged in a row on a horizontal coaxial line, for example, the first roll receiver _5-1 at the right end.
and the second roll receiver _5-2 next to it, the roll holding mechanism 6 and the first and second push-up mechanisms _7-1 , _7-2.
Continuous core breaking is possible by providing a roll conveying device that moves the vertical rolls 1 from left to right on the roll receiver each time the vertical rolls 1 are separated. The structure is the same as the illustrated example.

The present invention has the configuration and operation described above, and has the required number of creases 4, 4 that are attached in advance.
By using the winding core 2 with a series structure that can be separated by bending at the part, only one core needs to be supplied to the winding section of the slitter, and the core magazine, core supply/take-out, etc. The device can be summarized into a simple structure.

Further, while the vertical rolls 1 are received on the roll receivers _5-1 and _5-2 , the fold line 4 is moved by sequential operation of the roll holding mechanism 6 and the first and second push-up mechanisms _7-1 and _7-2 . , 4, and in that case each mechanism 6, _7-1 , _7-2 can be operated by simple linear reciprocating motion.
Due to its simple structure and easy control, it is an extremely useful device for completely automating roll processing immediately after slitting.
