(Summary of invention)

(Tasks to be solved by the invention)

For example, when cut | disconnecting the film which laminated | stacked various layers like the film for display panels, the film containing metals, such as a circuit electrode, etc. as a workpiece, a cut surface is clean and dimensional precision is strictly required, of course, In addition, it is required to suppress the sound of cutting and vibration of the device during cutting of the workpiece. However, the conventional cutting machine did not fully satisfy the demand for reducing the cutting sound and vibration. In particular, when the workpiece was hard or wide, the cutting sound and vibration tended to increase. Moreover, according to the characteristic of the film used as a workpiece | work, when cutting | disconnecting the thing of the blade edge of a workpiece | work at the time of cutting | disconnecting, when cutting a wide workpiece | work, the conventional cutter may have caused the side of a workpiece | work to slip off.

This invention is made | formed in view of the said situation, and an object of this invention is to provide the cutter which cut | disconnects with the cutting sound at the time of a cutting | disconnection, and the vibration of a device being small, and being able to cut | disconnect without causing the side of a workpiece | work.

The cutter according to the present invention,

A cutter for cutting a work by lowering a flat blade

A punching board provided at the bottom of the blade and configured to move up and down by inserting both left and right ends into the guide post;

A first eccentric mechanism for connecting the arm to one end of the punching plate and moving the one end side in the longitudinal direction of the blade up and down;

A second eccentric mechanism for connecting an arm to the other end side of the punching plate and moving the other end side in the longitudinal direction of the blade up and down;

And a control unit configured to simultaneously operate the first and second accent mechanisms to lower the blade horizontally, or to operate the first and second accent mechanisms with a time difference to tilt and lower the blades. do.

According to the accent mechanism, the pushing force of the blade against the work can be increased. Therefore, the drive source of the eccentric mechanism can be made a small load, and even a drive source of a small load can cut | disconnect a hard work and a wide workpiece smoothly. In addition, since the punching plate provided with the blade is supported by the insertion tube so as to be movable up and down on the guide posts at both left and right ends, the punching plate provided with the blade can be moved up and down smoothly. Therefore, the stress which a blade and an apparatus receive at the time of cutting a workpiece | work is alleviated, and the cutting sound and apparatus vibration at the time of cutting a workpiece can be suppressed small.

In addition, since the punching plate provided with the blade is moved up and down along the guide post at both the left and right ends, the work can be cut accurately and accurately. When the first and second eccentric mechanisms are operated with a time difference, the blades are inclined in a straight state without being bent in the front-back direction by elastic deformation allowed at the insertion passage portion of the guide post in the punching plate. Can be lowered.

As mentioned above, according to the characteristic of a workpiece | work, the cutting system which can suppress a cutting sound and apparatus vibration at the time of cutting a workpiece | work can be set.

In the cutter,

The control section follows the other end side in advance in the longitudinal direction of the blade with respect to the blade in a state where the edge of the blade is brought into contact with the overall width of the workpiece by the first and second accent mechanisms, and then descends by following the other end side. With the tip of the blade in an inclined position, the work is cut out from one side, and in the descending final position, the work is lowered so that the heights of both ends of the blade coincide, and the work is cut with the blade edge in a horizontal position. can do.

By the said structure, since the edge of a blade is made to contact the full width of a workpiece | work, and a workpiece is cut out from one side, the impact at the time of a contact of a blade and a workpiece can be suppressed. And the workpiece can be gradually cut from one end to the other end in the width direction by displacing the blade from the inclined posture to the horizontal posture while lowering the blade. This can prevent a large load from being applied to the blade and the workpiece during cutting of the workpiece. Therefore, even when the workpiece is hard or wide, the cutting sound and the vibration of the device at the time of cutting the workpiece can be suppressed small.

The cutting edge of the blade is brought into contact with the entire width of the workpiece when the workpiece is cut, so that the workpiece can be restrained by the blade itself when cutting the workpiece. Thereby, it can cut | disconnect straight in the state which hold | maintained the workpiece | work, without causing the side of a workpiece to come off at the time of cutting | disconnecting a workpiece | work. Therefore, when cutting the workpiece | work which should not be restrained other than a cut | disconnected part, a wide workpiece | work, etc., even if there is no workpiece paper-blocking member, it can cut | disconnect straight in the state hold | maintained without making a side deviate sideways.

In the cutter,

The blade unit is constituted by the blade holder which fixed the blade and the blade,

The blade holder is attached to the slide base of the linear guide mechanism installed in the punching plate,

A slide mechanism for sliding the blade unit laterally with respect to the punching plate via the linear guide mechanism to the blade unit or the slide base,

The said control part can be set as the control structure which cut | disconnects a workpiece | work by sliding a blade laterally and moving a blade unit horizontally by operating the said slide mechanism.

By sliding the blade laterally by the slide mechanism, the actual cutting angle of the blade with respect to the work can be made smaller, and the cutting ability of the blade can be sharpened to make the cutting surface of the work more clean. In addition, when one end side of the blade lowered earlier by the slide mechanism is slid in the lateral direction, the workpiece can be pulled out by the blade, and the load applied to the blade and the workpiece at the time of cutting the workpiece can be further reduced. . Therefore, the cutting sound at the time of cutting a workpiece | work and the vibration of an apparatus can be suppressed further.

Moreover, since a part of the blade unit which comprises a blade and a blade holder with a punching board is slid by a linear guide mechanism and a slide mechanism, a blade can be slid with low inertia. Therefore, even in the case of cutting a wide workpiece, it is possible to precisely control the movement in the horizontal direction of the blade, and to suppress the vibration and the cutting sound of the device caused by the horizontal movement of the blade.

In the cutter,

It is preferable that the blade suspension support position interval of each arm in the said 1st, 2nd eccentric mechanism is set to 1/2-1/3 with respect to the full length of a blade.

If the blade suspension support position interval, i.e., the distance between the connecting portions of the punching plate in each arm of the first and second eccentric mechanisms is wider than 1/2 of the total length of the blade, the exact center of the blade will bend during cutting. On the other hand, when the said space | interval becomes narrower than 1/3 with respect to the whole length of a blade, there exists a possibility that the both ends of a blade may bend at the time of cutting | disconnection. Therefore, even if the total length is a long blade (for example, 1 m or more), the blade suspension support position interval of each arm is set to 1/2 to 1/3 with respect to the total length of the blade so that the blade is not bent at the time of cutting. The workpiece can be cut straight by keeping it straight. In addition, when the blade is beveled, the difference between the rotation angles of the first and second accent mechanisms is neither small nor large, making it easy to control the first and second accent mechanisms. In addition, the blade suspension support position interval of each arm can be suitably set by the material, thickness, size, etc. of a workpiece | work, thickness of a blade, etc. within the range of 1 / 2-1 / 3 with respect to the full length of a blade. .

In the cutter,

It is preferable that the linear motion bearing provided with the rolling element passes through the said guide post, and is provided in the both end sides of the said punching board.

By this linear motion bearing, the punching board provided with a blade can be moved up and down smoothly, and the cutting sound and apparatus vibration at the time of cutting a workpiece can be suppressed small. Moreover, the linear motion bearing makes it easy to adjust the amount of elastic deformation permitted in the insertion passage portion of the guide post in the punching plate when the first and second eccentric mechanisms are moved at a time difference. In this case, even if it elastically deforms, the said punching board can be moved up and down smoothly by the said linear motion bearing.

As described above, according to the cutting machine according to the present invention, the cutting sound and the vibration of the device at the time of cutting the work can be suppressed, and even without the work restraining member, it can be cut straight in the state of holding it without causing side work. have. As a result, even when cutting a workpiece which should not be restrained except a hard workpiece or a cut portion such as a film including a laminated film or a metal or the like, or a wide workpiece, the cutting sound and device vibration during cutting are small and the dimensions are small. The precision is good and the cut surface can be cut cleanly.

EMBODIMENT OF THE INVENTION Below, embodiment is described, referring an accompanying drawing.

As shown in FIG. 1, the cutter 1 lowers the blade 2 suspended by the head 11, and arrange | positions the workpiece | work W arrange | positioned at the blade receiving member 14 attached to the mount 12. As shown in FIG. To cut. The workpiece | work W is various other films, such as the film which laminated | stacked several layers like the film for display panels, the film containing metals, such as a circuit electrode, a metal plate, etc., for example. The mount 12 is supported by the frame 15. The head 11 is attached to the upper part of the guide post 13 which stood two by the left and right ends of the mount 12, and is installed above the mount 12. As shown in FIG. And the box-shaped punching board 17 is inserted in the guide post 13 through the linear motion bearing 18 at the left and right both ends, and is comprised so that it can move up and down. In the lower part of this punching plate 17, the blade unit 20 which fixed the blade 2 to the blade holder 21 is arrange | positioned. Although not shown, the linear motion bearing 18 is provided with rolling elements, such as a roller or a ball, and is set so that rattling may not generate | occur | produce between the guide posts 13 and the like. As a result, when the blade 2 is moved up and down, the punching plate 17 is moved up and down along the guide post 13, thereby preventing the blade 2 from swinging back and forth.

Referring also to Figure 2, the blade unit 20 is composed of a blade (2) and the blade holder 21, the blade (2) has a flat plate shape in the transverse direction, the blade edge (2a) of both blades downward To the blade holder 21 and detachably attached to the blade holder 21 with a plurality of bolts 22. The blade unit 20 is attached to the linear guide mechanism 3 provided on the lower surface of the punching plate 17. The linear guide mechanism 3 is arranged to slide freely through the rollers of the rolling element 33 on the inside of the guide member 32 and the guide member 32 having a substantially cross-sectional shape attached to the lower surface of the punching plate 17. A slide base 31 having a substantially trapezoidal cross section is provided. The blade holder 21 of the blade unit 20 is attached to the lower surface of the slide base 31. Thus, the blade unit 20 is configured to slide freely in the transverse direction with the slide base 31 with respect to the punching plate 17.

To the head 11, the lower end of the arm 54 is connected to one end in the longitudinal direction of the punching plate 17, and the first eccentric mechanism 5 which moves one end side in the longitudinal direction of the blade 2 up and down; The second eccentric mechanism 6 which connects the lower end of the arm 64 to the other end side of the punching board 17 in the longitudinal direction, and moves the other end side of the blade 2 in the longitudinal direction up and down is arrange | positioned. . Then, the punching plate 17 is lowered by the first and second accent mechanisms 5 and 6 to the blade receiving member 14 on which the blade tip 2a of the blade 2 has placed the work W. The work is cut by lowering the blade 2 until it reaches it. Moreover, as the blade 2, the upper blade (moving blade) of one blade is attached to the blade holder 21, and the lower blade (fixing blade) which overlaps this upper blade is fixed to the mount 12, and the workpiece | work W is fixed. It is good also as a structure to cut | disconnect.

The first accent mechanism 5 eccentrically biases the first motor 51 constituted by the servo motor, the accent shaft 52 rotated and driven by the first motor 51, and the accent shaft 52. A cam 53 to be mounted and an arm 54 connected to the axial shaft 52 are provided. The lower end part of this arm 54 is attached to the support shaft 55 provided in the punching board 17 via the bearing guide 56 to the one end side of the punching board 17 in the longitudinal direction, and by the arm 54 The one end side of the punching board 17 in the longitudinal direction is suspended and supported. From this 1st accent mechanism 5, the rotational movement of the eccentric shaft 52 by the 1st motor 51 is converted into the up-down movement of the arm 54, and the end of the punching plate 17 in the longitudinal direction is carried out. By moving the side up and down, one end side of the blade unit 20 (blade holder 21 and the blade 2) arranged in the lower part of the punching board 17 is moved up and down. The second accent mechanism 6 is also configured in the same manner as the first accent mechanism 5, and the bearing guides are formed on the support shaft 65 provided at the lower end of the arm 64 in the punching plate 17. It is attached to the other end side of the punching board 17 in the longitudinal direction via 66, The arm 64 suspends the other end side of the punching board 17 in the longitudinal direction, and drives the 2nd motor 61. As shown in FIG. The other end side of the blade unit 20 (blade holder 21 and the blade 2) is moved up and down from the lower surface arm 64. As shown in FIG.

Here, the support shafts 55 and 65 of the lower end part of each arm 54 and 64 become a blade suspension support position. And the interval of the blade suspension support position (support shaft 55 and support shaft 65) in each arm 54 and 64 is set to 1/2-1/3 with respect to the full length of the blade 2, have. That is, when the blade suspension support position interval of each arm 54, 64 becomes wider than 1/2 with respect to the total length of the blade 2, the center of the blade 2 may be bent at the time of cutting, When the blade suspension support position interval of the arms 54 and 64 becomes narrower than 1/3 with respect to the total length of the blade 2, the both ends of the blade 2 may be bent at the time of cutting | disconnection. Therefore, even if the total length is long (for example, 1 m or more) of the blade 2, the blade suspension support position intervals of the arms 54 and 64 are 1/2 to 1/3 of the total length of the blade 2. By setting to, the work piece W can be cut straight while maintaining the straight state without bending the blade 2 at the time of cutting.

In addition, when the blade 2 is beveled at a predetermined angle, the difference in the stroke position of the arms 54 and 64 becomes closer as the blade suspension support positions of the arms 54 and 64 are closer to the end side of the punching plate 17. In order to lengthen, it is necessary to enlarge the difference of the rotation angles of the cams 53 and 63 of the accentical mechanisms 5 and 6, and the blade suspension support position of the arms 54 and 64 is the center side of the punching board 17. In order to shorten the difference between the stroke positions of the arms 54 and 64, it is necessary to make the difference in the rotation angles of the cams 53 and 63 of the eccentric mechanisms 5 and 6 small. By the way, the edge of the blade suspension support position of each arm 54, 64 is set to 1 / 2-1 / 3 with respect to the total length of the blade 2, and the cam of the 1st, 2nd axial mechanism 5, 6 is carried out. The difference between the rotation angles of the 53 and 63 is neither small nor large, making it easy to control the first and second eccentric mechanisms.

In addition, the blade suspension support position interval of each arm 54 and 64 is a material, thickness, size, etc. of the workpiece | work W within the range of 1 / 2-1 / 3 with respect to the full length of the blade 2, Or it can set suitably by the thickness of the blade 2, etc.

Moreover, the length adjustment mechanisms 54a and 64a are provided in each arm 54 and 64 in the 1st, 2nd eccentric mechanisms 5 and 6. As shown in FIG. These length adjustment mechanisms 54a and 64a screw the adjustment screw in which the nut of the opposite direction is provided in each end part to the bolt of the edge part which divided each arm 54 and 64, and this adjustment screw By rotating, the lengths of the arms 54 and 64 are adjusted. In addition, length adjustment mechanism 54a, 64a may be set as the structure which screwed the adjustment screw which provided the bolt in a reverse direction to the both ends, and the nut of the edge part which divided each arm 54, 64 into two.

In addition, the cutter 1 is provided with a slide mechanism 7 for sliding the blade 2 laterally. The slide mechanism 7 includes a third motor 71 composed of a geared motor or the like, an accent 72 for converting the rotational motion of the third motor 71 into a linear motion, and a straight line by the accent 72. And an arm 73 for transmitting exercise. This arm 73 is connected to the edge part of the blade holder 21 of the blade unit 20. As shown in FIG. Since the blade unit 20 slides freely in the transverse direction with respect to the punching plate 17 by the linear motion guide mechanism 3, the blade unit 20 is moved by sliding the blade unit 20 in the transverse direction by operating the slide mechanism 7. The workpiece | work W can be cut | disconnected by sliding (2) horizontally. By this slide mechanism 7, the lowering blade 2 can be moved horizontally on either side, and the work W is slid by cutting the blade 2 from either the left or right side, or the blade 2 is cut off. The workpiece W can be cut by various aspects according to the kind of the workpiece | work W, etc., such as sliding by cutting at an angle, or even swinging and cutting the blade 2. In addition, although the arm 73 of the slide mechanism 7 is connected to the blade holder 21, it is not limited to this, You may connect to the blade 2 or the slide base 31. FIG. The slide mechanism 7 may be a moving means such as a ball screw mechanism or a cylinder mechanism instead of the accent 72. In addition, although the slide mechanism 7 is provided in the one end side of the blade holder 21, it may be provided in the right and left both ends, and may not be provided with the slide mechanism 7 itself.

Moreover, in the cutter 1, the stopper 16 which maintains the edge part of the width direction of the workpiece | work W in the movement blocking state is provided. With reference to FIG. 3, the stopper 16 is provided so that the stopper 16 may contact back and front except the falling position of the blade 2 with respect to the edge part of the workpiece | work W. As shown in FIG. Thereby, the workpiece | work W can be hold | maintained so that the workpiece | work W may not arise in the width direction by the movement of the blade 2 at the time of cutting | disconnection, or cause troubles, such as causing looseness. Therefore, the cutting of the workpiece | work W can be cut | disconnected smoothly and cleanly also in the case where the one end side of the blade 2 is preceded, the other end side is followed, and it cuts down. Moreover, the stopper 16 is attached to the table of the mount 12 freely in the workpiece width direction, and can respond to various workpiece widths. In addition, although the stopper 16 is provided with respect to the both ends of the width direction of the workpiece | work W (refer FIG. 1), you may make it install only in one end side.

The cutter 1 is provided with a control part (not shown) which controls the operation | movement of the blade 2 at the time of cutting the workpiece | work W, and demonstrates an example of the operation | movement of the cutter 1 with reference to FIG. do. 4 shows the movement of the accent shafts 52 and 62 in the first and second accent mechanisms 5 and 6 on the left side, and the movement of the blade 2 corresponding to it on the right side.

First, when the workpiece | work W is arrange | positioned in the fixed position on the blade receiving member 14 by the conveyance means which is not shown in figure, the 1st, 2nd eccentric mechanism 5, 6 is moved, and the blade 2 The blade 2 is lowered to a position where the blade tip 2a horizontally contacts the entire width of the work W (Fig. 4 (a)). Thereby, the workpiece | work W is restrained by the blade 2 so that it may not move to the side, and a position is fixed.

Next, the first eccentric mechanism 5 is moved ahead of time, and the one end side of the blade 2 is lowered (Fig. 4 (b)), and the second eccentric mechanism 6 is followed by the operation for a certain time later. To lower the other end side of the blade 2 (Fig. 4 (c)). At this time, the operating speed (rotational speed of the second motor 61) of the second accent mechanism 6 is the same as that of the first accent mechanism 5. As a result, the blade tip 2a of the blade 2 is lowered in an inclined posture with one end as the lower position, and the work W is cut off from one end in the width direction (Fig. 4 (b) (c)).

Then, when the movable position of the first accent mechanism 5 is rotated near the end point, that is, the cam 53 is near the bottom dead center, the operating speed of the first accent mechanism 5 is decelerated (FIG. 4 (c). )), The movable position of the second accent mechanism 6 is fitted in accordance with the movable position of the first accent mechanism 5, and the blade tip 2a is lowered while being displaced from the inclined position to the horizontal position. As a result, the work W is gradually cut from one end to the other end in the width direction.

Then, at the descending final position, the bottom dead centers of the accent shafts 52 and 62 of the first and second accent mechanisms 5 and 6 are coincident with each other, and the blade tip 2a is placed in a horizontal position. When the full width is cut (Fig. 4 (d)), the cut of the work W is completed.

In addition, although the cutting operation | movement mentioned above is an example which does not operate the slide mechanism 7, between the time of starting to cut in the workpiece | work W and finishing cutting (FIG.4 (b)-(d)), the slide mechanism (7) may be moved, and one end side of the blade 2 may be pulled in the transverse direction to slide the blade 2 in the transverse direction.

Thus, according to the cutting machine 1 of this embodiment, since the blade edge | tip 2a of the blade 2 is cut out from one side of the workpiece | work W by making contact with the full width of the workpiece | work W, the blade 2 ) And the impact at the time of contact with the work W can be suppressed. Then, the work W is gradually cut from one end to the other end in the width direction by displacing the blade 2 from the inclined posture in a horizontal posture while lowering the blade 2, so that the blade 2 and the work W are cut at the time of cutting the work. It is possible to avoid a large load. Therefore, even when the workpiece | work W is hard or wide, the cutting sound at the time of cutting a workpiece | work and the vibration of an apparatus can be suppressed small.

In addition, the cutting edge 2a of the blade 2 is brought into horizontal contact with the full width of the workpiece W during the cutting of the workpiece W. Thus, the cutting blade 2 itself is the workpiece W when cutting the workpiece. Can be prevented from coming off the side of the work W, and can be cut straight while the work W is held. Therefore, when cutting the workpiece | work W which should not be restrained other than a cut | disconnected part, and the workpiece | work W which is wide and thin (for example, workpiece thickness / work width = 0.2-1mm / 1000-1600mm), etc., Even if there is no workpiece restraint member, the workpiece W can be cut straight without being held off to the side. Therefore, even when cutting the workpiece W which should not be restrained except the hard workpiece | work W and a cut part like a film containing a laminated film, a metal, etc., a metal plate, etc., or the wide workpiece | work W, etc. The cutting sound and vibration of the device are small, the dimensional accuracy is good, and the cutting surface can be cut cleanly.

In addition, since the operation of the blades 2 is performed by the accent mechanisms 5 and 6, the pushing down force of the blades 2 with respect to the work W can be increased. Therefore, even if the motors 51 and 61 which are the drive sources of the eccentric mechanisms 5 and 6 can be made into a small load, and even the motors 51 and 61 of a small load are hard, the hard workpiece W and the wide workpiece | work W ) Can be cut smoothly and reliably. In addition, since the punching plate 17 with the blade 2 is supported by the insertion tube so as to be movable up and down on the guide post 13 at both left and right ends, the punching plate 17 with the blade 2 is smoothly up and down. You can move it. Therefore, the stress which the blade 2 and the apparatus receive at the time of cutting a workpiece | work is alleviated, and the cutting sound and apparatus vibration at the time of cutting a workpiece can be suppressed small.

In addition, since the punching plate 17 having the blade 2 is moved up and down along the guide post 13 through the linear bearing 18 having the rolling elements on both left and right ends, the work W is cut precisely and accurately. can do. In the case where the first and second eccentric mechanisms 5 and 6 are operated with a time difference, the blades 2 are caused by elastic deformation allowed at the insertion passage portion of the guide post 13 in the punching plate 17. The blade 2 can be tilted and lowered in a straight state without being bent in the front-rear direction. In addition, when the first and second eccentric mechanisms 5 and 6 are moved by the time difference by the linear motion bearing 18, the insertion part of the guide post 13 in the punching plate 17 is allowed. The elastic deformation amount can be easily adjusted. Moreover, the linear motion bearing 18 can move the punching board 17 with the blade 2 up and down smoothly, and can cut down the cutting sound and apparatus vibration at the time of cutting a workpiece | work.

In addition, the slide mechanism 7 pulls one end side of the blade 2 laterally to slide the blade 2 also in the transverse direction, whereby the actual cutting angle of the blade 2 relative to the work W is made smaller. The cutting ability of the blade 2 can be sharpened, and the cut surface of the workpiece | work W can be made more clean. In addition, by pulling the one end side of the blade 2 to be lowered in the transverse direction, the workpiece W can be pulled out by the blade 2, and the cutting edge 2 and the workpiece W can be cut at the time of cutting the workpiece. The load applied can be further reduced. Therefore, the cutting sound at the time of cutting a workpiece | work and the vibration of an apparatus can be suppressed further.

Moreover, since the linear motion guide mechanism 3 and the slide mechanism 7 slide the part of the blade unit 20 which comprises the blade 2 and the blade holder 21 with respect to the punching board 17, The inertia can slide the blade 2. Therefore, even in the case of cutting the wide workpiece W, the movement in the lateral direction of the blade 2 can be precisely controlled, and the vibration and the cutting sound of the device accompanying the lateral movement of the blade 2 can be suppressed. Can be.

As mentioned above, according to the cutting machine 1, according to the characteristic of the workpiece | work W, the cutting system which can suppress a cutting sound and apparatus vibration at the time of cutting a workpiece can be set.

In addition, this invention is not limited to the said embodiment, It is possible to implement various changes within the range of the summary of this invention.

In the said embodiment, although the operation speed of the 1st eccentric mechanism 5 is decelerated (FIG.4 (d)), the operation speed of the 1st eccentric mechanism 5 is made constant as it is, and the 2nd eccentric mechanism ( You may increase the operation speed of 6), and may make the movable position of the 2nd eccentric mechanism 6 adhere to the movable position of the 1st eccentric mechanism 5.

Moreover, the 1st eccentric mechanism which previously started the operation speed of the 2nd eccentric mechanism 6 which starts the operation speed of the 1st, 2nd eccentric mechanisms 5 and 6 at constant speed, and starts it late ( You may make it faster than the operation speed of 5), and may match the movable positions of the 1st, 2nd eccentric mechanisms 5 and 6 in a descending final position.

Moreover, the movable position of the following 2nd eccentric mechanism 6 is ahead of the movable position of the preceding 1st eccentric mechanism 5, and in the descending final position of the 1st, 2nd eccentric mechanism 5, 6 The movable positions may be matched. Thereby, the blade 2 is inclined with one end side of the blade 2 in the lower position, and the blade 2 is then beveled with the other end side of the blade 2 in the lower position, and the work W ) Can be cut. Therefore, even when the workpiece | work W (for example, thickness of a workpiece | work is 1 mm or more) with comparatively thick, cutting sound and apparatus vibration can be suppressed and it can cut | disconnect smoothly.

In addition, first, when the blade tip 2a of the blade 2 is brought into contact with the entire width of the workpiece W (Fig. 4 (a)), the first and second eccentric mechanisms 5 and 6 are operated. Each arm 54, 64 is extended with the length adjustment mechanism 54a, 64a, the head 11 is lowered, or the table which attached the blade receiving member 14 of the mount 12 is raised, without making it stand. You may make it possible. For example, the head 11 may have a structure in which a lifting mechanism for vertically moving can be provided so that the height position can be freely adjusted, and the lifting mechanism is placed on a table on which the blade receiving member 14 is attached to the mount 12. It can be installed so that the height of the table can be adjusted freely.

In addition, the control unit may cause the work W to be cut by lowering the blade 2 in a horizontal position by simultaneously operating the first and second accent mechanisms 5 and 6. In this case, when making the workpiece | work W into a comparatively soft film, a narrow film, etc., the workpiece | work W can be cut | disconnected quickly in a state where cutting sound and apparatus vibration are small. In addition, the control unit enables the first and second accent mechanisms 5 and 6 and the slide mechanisms 7 and 8 to be appropriately moved to move the blade 2 horizontally while lowering the blade 2 horizontally, or the blade 2 The blade 2 may be moved in various aspects depending on the work W, for example, by moving the blade horizontally while lowering the blade 2 in an inclined position, or swinging the blade 2 downward while displacing the blade 2 from the inclined position to the horizontal position.

Moreover, you may provide a workpiece | work paper-making member, and restrains and hold | maintains the workpiece | work W in the vicinity of the blade 2 at the time of cutting a workpiece.
