[Field of design]

The present invention relates to a touch roll arm mounted on a slitting machine of a film, and more particularly, to press the surface of the film wound on a mill roll in the slitting device of the film. An arm that can facilitate an operation for lowering a touch roll.

[Prior art]

In general, in a slitting apparatus in which a film or paper is slit and wound on a mill roll, the touch roll is brought into contact with the surface of the film wound on the mill roll in order to prevent air from intervening between the wound film layers.

That is, referring to FIG. 1 of the accompanying drawings, the film 1) is wound around the outer circumference of the mill roll 4 mounted on the take-up shaft 5, and the rotatable arm 10 rotates around the arm axis 6. The outer circumferential surface of the touch roll 2 provided at the end pressurizes the surface of the film 1 wound by the mill roll 4. Pressurization of the film on the mill roll 4 by the touch roll 2 is usually performed by the weight of the arm 10 and the touch roll 2 or by the air pressure supplied from a separate system.

Before the start of the winding operation, the arm 10 is rotated around the arm shaft 6 so that the touch roll 2 is raised without being in contact with the mill roll 4. The raised state is maintained by engaging a key formed in the arm shaft 6 with a set key 21 provided in the journal portion 20 at the upper end of the arm 10.

When starting the work for the first time or replacing the mill roll 4 which has been wound up with a new mill roll 4, conventionally, the operator mounts the mill roll 4 on the take-up shaft 5 and then touches the roll 2 In order to lower the force, the set key 21 on the upper side of the arm 10 must be pressed by hand, for which the operator's hand has to pass through the lower side of the arm axis 6. On the one hand, this is an inconvenient operation, and on the other hand, it is a factor that lowers work efficiency.

[Purpose and composition of proposal]

Accordingly, an object of the present invention is to provide an arm with a touch that does not require the operator's hand to operate the set key directly through the lower part of the arm axis when lowering the touch roll that presses the film wound on the mill roll in the slitting apparatus of the film. will be.

In order to achieve the above object, the present invention is a touch roll for a film slitting device including a journal unit is rotatably suspended around an arm shaft is formed with a key groove, the set portion is pressed by a spring is engaged with the key groove of the arm shaft. In the arm, a fusible tube is installed through a flexible tube and a bow cable for pulling the set key and rotating in a direction opposite to the pressing direction by a spring. It provides a touch roll arm, characterized in that it further comprises a handle for pulling.

Description of Example

Hereinafter, preferred embodiments according to the present invention, illustrated in the accompanying drawings as a non-limiting example, will be described with reference to the drawings.

Referring to FIG. 4, a key slot 24 is formed on an outer circumferential surface of the journal portion 20 at the upper end of the arm 10, and a set key 21 is formed in the key slot 24. 22) It is pivotally supported. The bottom of the set key 21 is " ", The end of which is in engagement with the key groove 7 (see FIG. 1) formed in the arm shaft 6. The set key 21 is pressed clockwise by the spring 23. One end of the spring 23 is hung on the left edge of the key slot 24 and the other end is hung on the upper left side of the set key 21.

The bow cable 32 connected to the upper part of the set key 21 extends to the left of the figure. The bow cable 32 is intended to rotate around the key pin 22 by pulling the set key 21 in the direction opposite to the pressing direction by the spring 23. When the bow 32 is pulled, the set key 21 is rotated counterclockwise, and the lower end of the set key 21 comes out of the key groove 7 of the arm shaft 6, and accordingly the journal portion ( 20 is rotatable about the arm axis 6.

The bow cable 32 extends through the flexible tube 30, and as described above, the bow cable 32 is connected to the other end of the bow cable 32 connected to the set key 21. Handle 33 for pulling the is connected.

The handle 33 may be installed in a place where the operator's hand is easily accessible, and as shown in FIGS. 2 and 3, the flexible tube 30 may be provided with a plurality of fixing covers 31. The handle 33 for fixing the arm 32 along the outer circumferential surface of the 20 and the vertical side surface of the arm 10 and pulling the bow cable 32 is preferably installed near the lower end of the arm 10. Do.

The lowering of the touch roll arm according to the present invention as described above pulls the handle 33 so that the set key 21 is pulled out of the key groove 7 of the arm shaft 6 via the bow cable 32. The rotation of the arm 10 around the arm axis 6 is performed by the weight of the arm 10. In addition, when the winding of the film 1 to the mill roll 4 is completed, when the touch roll arm raises simply when the touch roll arm lowered by its own weight is pushed up to rotate around the arm axis 6 by a predetermined angle, By setting the set key 21 in the journal portion 20 of the arm 10 to be engaged with the key groove 7 of the arm shaft 6 by a spring 23, the arm 10 is arm arm 6. It is fixed with respect to).

[Effect of design]

By adopting such a touch roll arm for a film slitting device according to the present invention, the operator's hand passes through the lower side of the arm shaft and does not directly operate the set key, but conveniently by operating a handle installed at a convenient position where the hand can easily reach. Since the touch roll can be lowered, work efficiency is improved.

Claims (2)

Journal in which the key groove 7 is rotatably suspended around the arm shaft 6 formed thereon and is provided with a set key 21 pressurized by a spring 23 to engage the key groove 7 of the arm shaft 6.
