Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cutter device for cutting a web-like material such as a photographic print, a printing paper, and a copy paper into a set length.

[Conventional technology and its problems]

There are manual type and electric type cutters equipped with fixed blades and movable blades, but both cutters position the web-like object on the upper surface of the support table or one side of the outer periphery of the web-like object. Since the positioning guide is provided with a scale and the web-like material is aligned with the scale and cut into a predetermined length, there is a disadvantage that the cutting is very troublesome.

[Purpose of device]

Therefore, an object of the present invention is to provide a cutter device that solves the above-mentioned inconvenience and can efficiently cut a web-like material into a set length.

[Constitution of device]

In order to achieve the above-mentioned object, the present invention arranges a holding plate that can move up and down above a tip of a supporting base that supports a web-like object, and provides a spring that pushes down the pressing plate, and in front of the supporting base. Arrange a holder whose upper part is swingable, and attach a size regulating plate for positioning the tip of the web-like object to this holder. A rotary blade that is driven to rotate in the opposite direction and cuts the web-like material with the fixed blade is provided, and the rotary shaft of this rotary blade allows the downward movement of the pressing plate when the rotary blade rotates in the cutting rotation direction. In addition, a cam is attached to swing the holder backward.

[Action]

According to the above structure, by placing the web-shaped object on the support and inserting it between the fixed blade and the rotary blade, the tip of the web-shaped object is positioned by contacting the dimension regulating plate. Therefore, by rotating the rotary blade, the web-like material can be cut into a predetermined length. At the time of cutting, the pressing plate is lowered by the action of the cam and spring attached to the rotating shaft to push down the web-like object, so that the web-like object can be cut stably and the cam swings the holder backward. Therefore, the dimension control plate is separated from the tip of the web-like material, and as a result, the chips can be smoothly discharged.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, a support base 1 for supporting the web A.
A pair of positioning guides 2, 2 for positioning the side edges of the web-like material A are attached to both sides of the upper surface of the.

As shown in FIG. 3, a pressing plate 3 is arranged above the tip of the support base 1, and the protruding shaft 4 provided on the upper surface of the pressing plate 3 is formed on the bending plate 6 of the cover 5. It is slidably inserted in the guide hole 7.

A spring 8 is fitted on the outside of the protruding shaft 4, and the spring 8 pushes the pressing plate 3 downward.

Further, in front of the support base 1, as shown in FIGS. 3 and 4, a holder 9 is arranged, and an upper portion of the holder 9 is swingably supported by a pin 10.

The holder 9 is provided with a support plate 11, and a dimension regulating plate 13 for positioning the tip of the web A is attached to the tip of an L-shaped arm 12 which is superposed on the upper surface of the support plate 11. The arm 12 is provided with a long hole 14 and the long hole 14
The screw 15 inserted in is screwed into the support plate 11. Therefore, by loosening the screw 15, the position of the size regulating plate 13 can be adjusted in the inserting direction of the web-like material A placed on the support 1.

Further, a bending plate 16 is provided at the rear end of the support plate 11 of the holder 9, and the engaging hole 17 formed in the folding curve 16 is different from the hook piece 19 supported by the hinge 18 at the rear portion of the cover 5. When the holder 9 is swung rearward, the hook piece 19 is engaged with the engaging hole 17, and the engagement keeps the holder 9 swung backward. You can

It should be noted that when the hook piece 19 is deflected in the engaging direction by the elastic force of the spring and the holder 9 is swung backward,
It is preferable that the engagement part engages with the engagement hole 17 naturally.

A fixed blade 20 is provided between the support base 1 and the size regulation plate 13.
And a rotary blade 21 for cutting the web A with the fixed blade 20 and a rotary shaft 2 supporting the rotary blade 21.
2 is rotated by the crank mechanism 30 in the set angle forward and reverse directions.

As shown in FIG. 2, the crank mechanism 30 is provided with an eccentric pin 32 on an outer peripheral portion of a disc 31 rotated by a motor (not shown), and the eccentric pin 32 is attached to the rotary shaft 22. The crank shaft 33 is inserted into the long hole 34 of the attached crank arm 33, and the rotary shaft 22 is rotated by the rotation of the disc 31.

Fan-shaped cams 35 are attached to both ends of the rotary shaft 22, and arc-shaped holes 36 centered on the rotary shaft 22 are formed on the outer peripheral portion of the cam 35. A pin 37 is inserted into the arcuate hole 36, and the pin 37 is supported by blocks 38 attached to both ends of the upper surface of the pressing plate 3.

The pin 37 is normally supported at one end of the arcuate hole 36,
Due to the support, the holding plate 3 is held in a state of being separated from the support base 1.

Further, the cam follower 39 attached to the side surface of the holder 9 is in contact with the outer peripheral portion of the cam 35, and the cam 35
When is rotated, the holder 9 swings backward around the pin 10.

The cutter device shown in the embodiment has the above-described structure. When the web-like material A is cut, the size-regulating plate 13 is adjusted and then the web-like material A is placed on the support base 1 and the web-like material is placed. Insert A to the position where it comes into contact with the size regulating plate 13 and rotate the rotary blade 21 in the set angle forward and reverse directions.

Now, when the rotary blade 21 is rotated in the direction of the arrow in FIG. 3 after inserting the web-shaped material A to the position where the tip of the web-shaped material A contacts the size regulating plate 13, the cam 35 rotates together with the rotary blade 21. Arcuate hole 3 for supporting the pin 37 for
One end of 6 moves downward. Therefore, the pressing plate 3 is lowered by the elastic force of the spring 8 and presses the web-like material A,
After the pressing, the web-like material A is cut into a predetermined length by the rotary blade 21 and the fixed blade 20.

Further, when the rotary blade 21 is rotated in the cutting direction, the holder 9 is pushed by the cam 35, so that the holder 9 swings backward around the pin 10 and the dimension regulating plate 13 separates from the tip of the web-like material A ( (See Figure 5). Therefore, the chips of the web-like material A cut by the fixed blade 20 and the rotary blade 21 are smoothly discharged downward and are appropriately discharged along the discharge guide 40 arranged behind the fixed blade 20. It

After cutting the web A, the rotary blade 21 rotates in the opposite direction,
Since the cam 35 also rotates together with the rotary blade 21, the pressing plate 3 is pulled upward by the engagement of the pin 37 with one end of the arc-shaped hole 36.

When the rotary blade 21 is rotated, a motor for rotating the disk 31 may be driven by an operator's switch operation, or the tip end of the web-like material may be positioned by the size regulating plate. With a sensor to detect
The motor may be driven by an output signal from this sensor.

When the web-like material is cut to an arbitrary length, the holder 9 is swung backward, the hook piece 19 is engaged with the engaging hole 17, and the holder 9 is held in a state of being pulled backward. Keep it.

〔effect〕

As described above, according to the present invention, the size regulating plate for positioning the tip of the web-like object is provided in front of the fixed blade and the rotary blade. By rotating the, the web-shaped material can be cut into a certain length, and the cutting work can be performed efficiently.

Further, when the rotary blade starts to rotate in the cutting direction of the web-like material, the pressing plate descends and presses the web-like material, so that the web-like material is stable and can be cut accurately.

Furthermore, after the web-like material is cut, the size regulating plate escapes backward, so that the chips can be discharged very smoothly.
