Abstract

PURPOSE:To strip the cutting end of a belt-shaped member from a lower cutter without generating a deformation, in a cutting device which can convert the cutting direction of the belt-shaped member. CONSTITUTION:When the cutting angle of a belt-shaped member is converted, an inclined frame 18, a stripping plate 64, and the like are inclined integrally following the conversion of the cutting angle. In this case, the driving force of the inclined frame 18 is transmitted to a rotary arm 60 through a rotating mechanism 85, so as to rotate the rotary arm 60 at the same angle as the cutting angle of the inclined frame 18, in the reverse direction to the angle converting direction. As a result, the moving direction of the stripping plate 64 is corrected in the direction same as the flow direction of the belt-shaped member, and the deformation of the cutting end of the belt-shaped member in the stripping condition can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band-shaped member cutting device for cutting while pressing a band-shaped member near a cutting end against a lower blade.

[0002]

2. Description of the Related Art Conventionally, in order to improve the cutting accuracy (straightness of the cutting end, etc.) of a belt-shaped member such as a rubberized cord ply, the belt-shaped member near the cutting position is pressed against the lower blade by a pressing plate prior to cutting. , It is performed to prevent the strip-shaped member from being displaced or deformed during cutting.However, when the vicinity of the cutting position of the strip-shaped member is pressed against the lower blade by the pressing plate in this way, the pressing plate is removed from the strip-shaped member after completion of cutting. Even if they are separated from each other, the cut end of the strip-shaped member remains in close contact with the lower blade, and the strip-shaped member cannot be conveyed in the flow direction.

In order to prevent such a situation, the cutting end of the strip-shaped member may be peeled off from the lower blade immediately after the strip-shaped member is cut, and the applicant of the present invention can perform such an operation. Japanese Patent Application No. 4-203156 (July 7, 1992)
Japanese application). This is a thin stripping plate extending parallel to the lower blade between the strip member and the lower blade, and when the pressing plate releases the pressing against the strip member, the stripping plate is moved in a state parallel to the lower blade. And a moving mechanism that is inserted between the strip-shaped member and the lower blade that are in close contact with each other by the pressing to separate the cut end of the strip-shaped member from the lower blade.

[0004]

In the band-shaped member cutting device proposed by the present applicant, the direction in which the band-shaped member is cut is orthogonal to the flow direction of the band-shaped member (width direction of the band-shaped member).
However, if the peeling means of such a cutting device is directly applied to a cutting device in which the cutting direction of the belt-shaped member can be changed, the cutting end of the belt-shaped member is affected by the peeling plate at the time of peeling. There is a problem that the quality of the band member that is deformed and cut out is deteriorated. The reason is that the moving direction of the peeling plate is limited to one direction orthogonal to the lower blade, that is, the crossing angle between the extending direction of the lower blade and the moving direction of the peeling plate is limited to one value of 90 degrees. ,
Trying to change the cutting direction of the belt-shaped member, lower blade, upper blade,
When the peeling plate or the like is integrally tilted with respect to the belt-shaped member, the moving direction of the peeling plate is tilted with respect to the longitudinal direction of the belt-shaped member. As a result, the peeling plate is moved to move the belt-shaped member to the lower blade. This is because, if the peeling plate is to be peeled off, the cut end portion is deformed by the component force in the width direction due to the adhesion and friction between the peeling plate and the belt-shaped member.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cutting device for a band-shaped member, which is capable of changing the cutting direction of the band-shaped member and peeling the cutting end of the band-shaped member from the lower blade without deforming it. And

[0006]

SUMMARY OF THE INVENTION Such an object is to provide an inclined frame which can change the inclination angle with respect to the direction orthogonal to the flow direction of the belt-shaped member and extends across the belt-shaped member, and an inclined frame immediately below the belt-shaped member. A linear lower blade that is supported and extends along the inclined frame, and is supported by the inclined frame above the belt-shaped member and moves to cooperate with the lower blade to move the belt-shaped member over the entire width at the inclined angle. An upper blade to be cut and a supporting means supported by the inclined frame, when the strip-shaped member is cut by the upper and lower blades, a pressing means for pressing the strip-shaped member near the cutting position to the lower blade, and a lower blade between the strip-shaped member and the lower blade. A thin strip plate extending parallel to
When the pressing means releases the pressing on the belt-shaped member,
The peeling plate is moved in a state of being parallel to the lower blade, and is inserted between the strip-shaped member and the lower blade which are in close contact with each other by the pressing to separate the strip-shaped member from the lower blade, and the inclination of the inclined frame. When the angle is changed, the moving direction of the peeling plate by the moving means is shifted in the opposite direction to the angle changing direction of the inclined frame by the same angle as the changing angle, and is corrected so as to be the same as the flow direction of the belt-shaped member. Means, and can be achieved.

[0007]

Now, the inclined frame is inclined at a predetermined inclination angle with respect to the direction orthogonal to the flow direction of the belt-shaped member, and the cutting tip of the belt-shaped member cut on the lower blade at the same angle as the inclination angle. Is located. Next, after the strip-shaped member is conveyed by a predetermined length in the flow direction, the strip-shaped member is cut by the upper and lower blades. At this time, first, the strip-shaped member near the cutting position is pressed against the lower blade by the holding means. next,
The upper blade is moved, and the strip-shaped member is cut at the cutting position by the upper blade and the lower blade over the entire width at the inclination angle. Next, the pressing of the pressing means against the band-shaped member is released, but at this time, since the inclined cutting end of the band-shaped member is in close contact with the lower blade by the pressing, the moving means is operated to remove the thin stripping plate. While being parallel to the lower blade, it is moved in the flow direction of the strip-shaped member to be inserted between the cut end of the strip-shaped member and the lower blade, and the cut end of the strip-shaped member is separated from the lower blade. By repeating such an operation, the strip-shaped member is cut to a predetermined length one after another, but when the cutting angle of such a strip-shaped member is changed, the tilt frame is tilted and the tilt angle is changed to the cutting angle. Change according to. Here, since the above-mentioned peeling plate is supported by the tilt frame, it tilts integrally with the tilt frame,
When the moving direction of the peeling plate is limited to one direction, the moving direction of the peeling plate is inclined with respect to the flow direction of the strip-shaped member due to the angle change, and the cut end portion of the strip-shaped member is deformed at the time of peeling. May cause Therefore, in the present invention, when the tilt angle of the tilt frame is changed as described above, the correcting means shifts the moving direction of the peeling plate in the direction opposite to the angle changing direction of the tilt frame by the same angle as the change angle. Then, the flow direction of the strip-shaped member is adjusted to be the same. As a result,
The stripping plate always moves in the flow direction of the strip-shaped member regardless of the change of the inclination angle of the slant frame, and the cut end of the strip-shaped member is not deformed at the time of stripping. Can be cut out.

According to the second aspect of the present invention, the moving direction of the peeling plate can be corrected with high accuracy while the structure is simple. Further, according to the third aspect, it is possible to eliminate the position change of the peeling plate with respect to the lower blade when the tilt angle of the tilt frame is changed, and to minimize the stroke length of the piston rod of the cylinder.

The tilt angle K of the tilt frame 18 can be changed. Here, such tilting frame 18 is rocked by driving a motor (not shown), but at the time of this rocking, both longitudinal ends of the lower beam 19 form an arc centered on the fixed shaft 27. Guided by an arcuate guide 28 extending along.

An inclined frame 18 is provided just above the lower beam 19.
A lower blade holder 31 extending along the lower blade holder 31 is installed, and a lower blade 32 extending linearly along the inclined frame 18 is attached to the front end of the lower blade holder 31. The lower blade holder 31 has both ends thereof via spacers (not shown) fixed to the upper surface of the lower beam 19 outside the conveyor belt 14, and the longitudinal center is the central portion of the lower beam 19. It is supported by an inclined frame 18, that is, a lower beam 19 via a spacer (not shown) fixed to the upper surface and penetrating the gap 15. As a result, the lower blade 32 is supported by the inclined frame 18 via the spacer and the lower blade holder 31.

The motor 47 operates to drive the belt 46, and the carriage 38 and the movable case 40 are guided by the guide rail 37 so as to be integrated with each other. When moving in the longitudinal direction, the upper blade 42 moves while rotating in contact with the lower blade 32.

It is located on the central axis. Further, the peeling plate 64 has a small thickness in the vertical direction, and when the peeling plate 64 is in the standby position, it is a pressing plate.
It is arranged between the strip-shaped member B behind 53 and the lower blade 32 and the lower blade holder 31. And this peeling plate 64 is
When the pressing plate 53 is lifted and the pressing against the band-shaped member B is released, the piston rod 63 of the cylinder 62 projects synchronously, so that the lower blade 32 is provided between the band-shaped member B and the lower blade 32.
However, since the rotating arm 60 and the cylinder 62 are parallel to each other, the moving direction is the same as the flow direction of the belt-shaped member B and the extending direction of the rotating arm 60. Then, when moved in this manner, the peeling plate 64 is inserted between the strip-shaped member B and the lower blade 32 which are in close contact with each other by the pressing, and the strip-shaped member B is separated from the lower blade 32.

A first external gear 68 is fixed to the fixed shaft 27, and a lower end portion of a vertical shaft 69 whose upper end is fixed to the intermediate plate 22 is attached to the first external gear 68 via a bearing 70. The meshing second external gear 71 is rotatably supported. Reference numeral 72 denotes a toothed pulley rotatably supported on the vertical shaft 69 via the bearing 70.

A toothed belt 81 is stretched between the toothed pulley 80 and the toothed pulley 74, and a fourth external gear 82 meshing with a third external gear 79 is attached to the lower end of the rotating shaft 59. Is fixed. Reference numeral 83 is a connecting rod that connects the tips of the pair of rotating arms 60, and the connecting rod 83 extends parallel to the peeling plate 64.

When the tilt frame 18 swings counterclockwise in FIGS. 1 and 4 about the fixed shaft 27 by a predetermined change angle, the second external gear 71 meshes with the first external gear 68 and the The first external gear 68 revolves in the counterclockwise direction, so that the second external gear 71 rotates about the vertical axis 69 in the counterclockwise direction. The counterclockwise rotation of the second external gear 71 is caused by the toothed pulley 72, the toothed belt 76, and the toothed pulley 7

3, 74, 80 and the toothed belts 76, 81 as a whole, when the tilt angle of the tilt frame 18 is changed,
Both rotating arms 60 receive the driving force from 18 and tilt the frame
It is rotated by the same angle as the changing angle in the direction opposite to the angle changing direction of 18 so that the moving direction of the peeling plate 64 is always the same as the flow direction of the strip-shaped member B regardless of the change of the inclination angle K. The moving mechanism 85 and the pair of rotating arms.
The 60 and the turning mechanism 85 together constitute the correction means 86.

Next, the operation of the embodiment of the present invention will be described. Now, the inclined frame 18 is inclined at a predetermined inclination angle K with respect to the direction orthogonal to the flow direction of the strip-shaped member B, and the cutting edge 32a of the lower blade 32 is cut at the same angle as the inclination angle K. It is assumed that the cut tip of the strip-shaped member B is positioned. Next, operate the conveyor 11 to operate the conveyor belt.
14 carrying parts are carried in the direction of the arrow (forward), and the belt-shaped member B
Is conveyed for a predetermined length in the flow direction.

Next, the strip-shaped member B is moved by the upper and lower blades 42 and 32.
Is cut at the same angle as the inclination angle K. In this case, first, the piston rod 52 of the cylinder 51 is caused to project synchronously and the pressing plate 53 is lowered until it comes into contact with the belt-shaped member B. As a result, the strip-shaped member B near the cutting position, here immediately after the cutting position, is moved by the pressing plate 53 to the lower blade 32.
It is pressed against and is prevented from being deformed or displaced. Next, when the motor 47 is operated and the belt 46 is run, the carriage
The movable case 40 and the movable case 40 move along the lower blade 32 while being guided by the guide rails 37. At this time, the upper blade 42, which is supported by the movable case 40 so as to be freely rotatable, moves together while rotating while being in contact with the lower blade 32, and the belt-shaped member B cooperates with the lower blade 32 to move the entire width at the cutting position. Cut across. Next, the piston rod 52 of the cylinder 51 is synchronously retracted to raise the pressing plate 53 and release the pressing of the strip-shaped member B near the cutting position (cutting tip). At this time, since the inclined cutting tip of the strip-shaped member B is in close contact with the lower blade 32 by the pressing, it has to be peeled from the lower blade 32.

In this case, first, the piston rod 63 of the cylinder 62 is made to project synchronously so that the thin stripping plate 64 is moved in the flow direction of the strip-shaped member B while being parallel to the lower blade 32. It is inserted between the cutting edge of the strip-shaped member B and the lower blade 32 which are in close contact with each other. As a result, the cutting tip of the belt-shaped member B is reliably separated from the lower blade 32.
Next, the piston rod 63 of the cylinder 62 is synchronously retracted, the peeling plate 64 is returned to the initial position, the motor 47 is operated to run the belt 46, and the carriage 38, the movable case 40, and the upper blade 42 are moved. Return to the initial position.
Then, by repeating such an operation, the strip-shaped member B is successively cut at the same angle as the inclination angle K.

Next, when the cutting angle of the belt-shaped member B is changed, the tilt frame 18 is swung about the fixed shaft 27 by a predetermined change angle, and the tilt angle K is changed.
Is changed according to the cutting angle of the strip-shaped member B. At this time, since the above-mentioned peeling plate 64 is supported by the inclined frame 18, it swings together with the inclined frame 18, but the moving direction of the peeling plate 64 is limited to one direction, that is, the lower blade 32. When the crossing angle between the extending direction of the peeling plate and the moving direction of the peeling plate 64 is limited to one value, the moving direction of the peeling plate 64 is inclined with respect to the flow direction of the strip-shaped member B. Therefore, as described in the related art, the cutting tip portion of the belt-shaped member B may be affected by the movement of the peeling plate 64 and may be deformed. However, in this embodiment, when the tilting frame 18 is swung as described above, the second external gear 71 revolves around the first external gear 68 while rotating around the first external gear 68, and the rotation of the second external gear 71 rotates. Has toothed pulley 7
2, toothed belt 76, toothed pulleys 73, 74, toothed belt 81, toothed pulley 80, third external gear 79, fourth external gear 82,
Since both are transmitted to the rotating arm 60 via the rotating shaft 59, both rotating arms 60 are connected to each other by the connecting rod 83.
Is rotated in the direction opposite to the angle changing direction (swing direction) of the inclined frame 18 by the same angle as the changing angle, and is corrected so as to maintain the state parallel to the flow direction of the belt-shaped member B. Here, since the longitudinal direction of each rotating arm 60 and the moving direction of the peeling plate 64 due to the operation of the cylinder 62 are the same, the moving direction of the peeling plate 64 is also corrected to be the same as the flow direction of the strip-shaped member B. . Thus, even if the tilt angle K of the tilt frame 18 is changed, the moving direction of the peeling plate 64 is always corrected by the correction means 86 to be the same as the flow direction of the strip-shaped member B regardless of the change of the tilt angle K. Therefore, it is possible to prevent a situation in which the cutting tip of the band-shaped member B is deformed when peeled off, and it is possible to cut out the band-shaped member B of high quality. Moreover, the moving direction of the peeling plate 64 can be corrected with high accuracy while the structure is simple as described above.

When the tilting angle K of the tilting frame 18 is changed and the turning arm 60 is turned following as described above, the connection point P between the peeling plate 64 and the piston rod 63 is displaced, and the peeling plate 64 is moved. Although the relative position of the lower blade 32 to the lower blade 32 may change, in this embodiment, the cylinder 62
The connecting point P when the piston rod 63 is at the stroke end on the retracted side is positioned on the rotation axis L of the rotating arm 60, that is, on the central axis of the rotating shaft 59. The position of the connecting point P does not change even when the tilt frame 18 is rotated by the tilt of the tilt frame 18, and as a result, the relative position of the peeling plate 64 to the lower blade 32 is prevented from changing. Since the position change of the peeling plate 64 is eliminated, it is not necessary to increase the stroke length of the cylinder 62 for compensating the position change, and the stroke length of the piston rod 63 of the cylinder 62 is minimized.
