JPH08173833A - Method of feeding end film into pulverizer and device therefor - Google Patents

Abstract

PURPOSE: To provide a method of feeding an end film into a pulverizer and a device therefor in which breakage of an end film generated from a slitter from a film producing process and fed into a pulverizer due to pulverizing shock is prevented to continuously pulverize the end film. CONSTITUTION: When end films generated from a slitter from a film producing process are fed into a cutter, plural end films are twisted in advance. This method is achieved by a device which at one end of a hollow rotating shaft 1 almost horizontally arranged, a roll 2 of one end film is supported, and the other end film 3 is fed into a pulverizer 4 from the other end through the inside of the shaft, and by the rotation of the hollow rotating shaft 1, one end film 2 is rotated around the other end film 3 to form the twist in the end film.

Field of the Invention The present invention relates to a method and an apparatus for supplying an ear film to a crusher, which prevents breakage of the ear film due to a crushing shock and enables continuous crushing of the ear film. The present invention relates to the above-mentioned supply method and supply device.

[0002]

2. Description of the Related Art A film delivered from a film forming process has its both end ears cut by an ear cutter. Then, the cut ear film is supplied to the crusher and crushed. By the way, when crushing the ear film, the ear film is broken by the crushing shock, and each time,
There is a problem that manual re-injection work is required.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is a crushing shock of an ear film which is generated from a slitter in a film forming process and is supplied to a crusher. It is an object of the present invention to provide a method and a device for feeding an ear film to a crusher, which prevents breakage due to the above and enables continuous crushing of the ear film. .

[0004]

That is, the first aspect of the present invention
The point of this is to supply the ear film generated from the slitter from the film forming process to the cutting machine, and a method of supplying the ear film to the crusher characterized by inserting twists into a plurality of ear films in advance. Exist in.

A second gist of the present invention is a feeder for a crusher of an ear film used in the above-mentioned feeding method, wherein one ear is provided at one end of a hollow rotary shaft arranged substantially horizontally. The roll of film is supported, and the other ear film is fed to the crusher from the other end through the shaft, and the rotation of the hollow rotating shaft causes one ear film to swivel around the other ear film. There is provided a device for supplying an ear film to a crusher, characterized in that a twist is formed on the partial film.

A third gist of the present invention is a feeder for a crusher of an ear film used in the above feeding method, which is fed from one end into a hollow rotary shaft arranged substantially horizontally. A sandwiching plate for combining a plurality of ear films supplied to the crusher is arranged, and by the rotation of the hollow rotating shaft, a twist is formed in the plurality of ear films combined by the sandwiching plate. The present invention resides in a feeding device for a crusher of an ear film, which is characterized in that

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is an explanatory view showing an example of the supply device of the present invention, FIG. 2 is an explanatory view showing another example of the supply device of the present invention, and FIG. 3 is an example of a sandwich plate in the supply device shown in FIG. It is an explanatory view shown.

A typical film to which the present invention is applied is a biaxially stretched polyester film. The biaxially stretched polyester film is formed by extruding a molten polyester resin through a die of an extruder and electrostatically adhering it onto a cooling rotary drum to form a sheet, and then forming a sheet by a roll stretching machine and a stenter. It is obtained by stretching in the axis.

Then, the full width film sent out from the stenter by the transport roll is cut by the ear cutter into the ear film at both ends and the product film in the center, which are not products, and the product film is wound on the winder. Taken. On the other hand, the ear film is supplied to the crusher and crushed.

The ear film supply method of the present invention is characterized in that, when the ear film generated from the slitter in the film forming process is supplied to the cutting machine, a plurality of ear films are pre-twisted. . The twisted ear films have increased tensile strength, so that they do not break due to crushing shock in the cutting machine. The twist of the ear film is formed using the illustrated inventive feeder.

In the feeding device shown in FIG. 1, one ear film roll (2) is supported at one end of a hollow rotary shaft (1) arranged substantially horizontally, and the other ear part is passed through the shaft from the other end. The film (3) is supplied to the crusher (4), and the rotation of the hollow rotary shaft (1) causes one ear film (2) to swirl around the other ear film (3) and the ear film. It is characterized in that it is provided with a structure in which a twist is formed. In addition,
In the figure, reference numeral (5) is a drive motor for the hollow rotary shaft (1),
Reference numeral (6) represents a supporting carriage for another ear film (3). Usually, each of the above-mentioned ear films is wound around a hollow winding core or the like and set in the above-mentioned feeding device.

The feeding device shown in FIG. 2 has a plurality of ear films (3), () fed from one end into the hollow rotary shaft (1) arranged substantially horizontally and fed to the crusher (4). 3)
The sandwich plate (7) shown in FIG. 3 for arranging the two is arranged, and by the rotation of the hollow rotating shaft (1), a twist is formed in the plurality of ear films that are combined by the sandwich plate (7). It is characterized by consisting of. The sandwich plate (7) is a hollow rotary shaft (1).
The plate-like bodies (72) and (72) urged by the springs (71) and (71) are arranged to face each other substantially at the center of the inside. The symbol (73) in FIG. 3 represents a screw for adjusting the biasing force of the spring.

[0013]

As described above, according to the present invention, since the ear film supplied to the crusher is prevented from being broken, the ear film can be continuously crushed and a great labor saving can be achieved. .
