Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cutting device for a strip-shaped film used in a laminator, etc., and in particular, it laminates a transparent strip-shaped film on the surface of a label or the like and cuts the film at a desired position. The present invention relates to a cutting device for strip-shaped film.

(Object of the Invention) The present invention provides a belt-shaped film cutting device in which a transported film belt passes between a rotary cutter and a fixed base roller, and the film is cut by the rotation of the rotary cutter. The purpose is to

(Example) Next, one embodiment of the present invention will be described based on the drawings.

Figure 2 shows a film laminator 1 to which this embodiment is applied.
2 is an overall plan view of the unwinding roll arm 3 provided on the side surface of the machine board 2. A strip-shaped label member 4 as a printing medium is provided on the unwinding roll arm 3 provided on the side surface of the machine board 2.
, the cutting device 8 according to the invention, the pinch roller 9 , an idle roller 10 biased in the direction of the pinch roller 9 , and then a turning roller 11 before being wound onto a winding roll 12 . Barcodes and other necessary information are preprinted on the label member 4 by a desired printer (not shown). A tension bar 13 is elastically brought into contact with the roll of the label member 4 to stabilize the unwinding tension.

Further, the transparent film 14 is unwound from the film unwinding shaft 15 and passes through the idle roller 16 to the film setting table 17, and the film pasting which is urged in the direction of the film setting table 17 is partially applied to the label member by the roller 18. 4, passes through the transport path of the label member 4,
The laminate M is formed by being stacked on the label member 4 and is wound up as a winding roll 12.

FIG. 5 shows this laminate M, in which the label member 4 has a label L temporarily attached to a mount S, and a film 14 can be laminated thereon to protect the printed content P. It is now possible to do so.

Then, this laminate M is cut at the cutting line C using a cutting device 8, so that a laminate label A of any size can be obtained.

A drive motor (not shown) equipped with a slip mechanism is provided to take up the winding roll 12, and a step motor (not shown) is used to drive the pinch roller 9.

FIG. 1 shows the cutting device 8 in detail with the two-sided cover 19 (FIG. 2) removed. The fixed base roller 21 is inside the cover 20, and the rotary cutter 2 is inside the cover 22.
3 is stored. The rotary cutter 23 is provided on a cutter base 25 and a cutter holder 26 provided on a drive shaft 24, and the distance between the rotary cutter 23 and the base roller 21 can be adjusted by screws 28 and 29 in an adjustment groove 27.

FIG. 3 schematically shows the drive mechanism of the cutter assembly 30 of the rotary cutter 23. An induction motor 31 drives a spiral gear 33 and a gear 34 via a variable speed gear 32. A clutch mechanism 35 is provided between the cutter assembly 30 and the gear 34.

FIG. 4 shows this clutch mechanism 35, in which a solenoid 36 drives a trigger 37, and a latch 38 drives a gear 34.
By meshing with the cutter assembly 30, the driving force of the induction motor 31 can be transmitted to the cutter assembly 30. still,
Reference numeral 39 is a latch shaft, and 40 is a stopper.

(Function) When the laminator 1 is started, the laminated label member 4 and film 14 (that is, the laminate M) pass through the sensor 7 section, and the cutter cutting device 8 cuts the laminate film according to the label pitch according to the detection signal. will be carried out.

That is, the solenoid 36 is energized in response to the detection signal from the sensor 7, the trigger 37 and the latch 38 are disengaged, the gear 34 and the latch 38 are engaged, and the clutch mechanism 35 and the gear 34 are connected. , the cutter assembly 30 rotates and cuts the label member 4 and film 14 passing between the fixed base roller 21 and the rotating cutter 23 at a predetermined position (cutting line C).

Incidentally, at the same time that the engagement between the trigger 37 and the latch 38 is disengaged, the solenoid 36 is deenergized, the trigger 37 returns to its original position and is engaged with the latch 38, and the cutter assembly 30 stops after one rotation.

In addition, the distance between the fixed base roller 21 and the rotary cutter 23 can be adjusted by loosening the screw 28, loosening the cutter 23 and the cutter holder 26, and then operating the adjustment screw 29, depending on the thickness of the film 14. Te film 14
Adjustments can be made not only when cutting only the label member 4 but also when cutting the label member 4 together with the film 14.

Although a case has been described in which the printed label member 4 is supplied in a roll, the printer and the present machine may be directly connected and the printed label member may be directly introduced into the present machine.

(Effects of the Invention) As described above, the present invention cuts the film by rotating the rotary cutter facing opposite to the fixed base roller, so by adjusting the rotary cutter, the film of any thickness can be cut at any position. It is possible to obtain a laminate in which a film that protects the label printing is laminated.
