Definitions
- One apparatus for cutting a sheet material used with a copier known in the art comprises a fixed cutter 2 disposed over one surface of the photosensitive sheet material I paid out from the roll and arranged to extend along the width thereof, and a movable cutter 3 disposed below the other surface of the photosensitive sheet material I to cooperate with the fixed cutter 2 as shown in FIG. 1.
- the photosensitive sheet material is cut by a cutting edge of the fixed cutter and a cutting edge 30 of the movable cutter as the movable cutter 3 is rotated in the direction of the arrow A.
- the prior art apparatus for cutting a sheet material referred to hereinabove has disadvantages.
- the operation of replacing the cutters, particularly the movable cutter, with new cutters is troublesome and time consuming when the cutting edges of old cutters are worn.
- the movable cutter is high in cost.
- the resistance of the sheet material markedly increases as the cutting edges of the cutters are worn.
- This type of sheet material cutting apparatus has a short service life when it is used for cutting a magnetic sheet material for transferring magnetic recordings because it is required to cut a large number of sheets from a roll of magnetic sheet material in this case.
- This invention relates to apparatus for working on paper, fabric and other sheet material and deals more particularly with an improved apparatus for cutting a sheet material.
- An object of this invention is to provide an improved apparatus for cutting a sheet material which obviates all the disadvantages of prior art apparatus for cutting a sheet material.
- Another object of the invention is to provide an apparatus of the type described in which an annular cutter used as a movable cutter can be made to operate effectively as it is moved along a cutter receiving member which cooperates with it.
- Another object of the invention is to provide means for supporting the annular cutter which permits to effect adjustments of the angle of contact between the annular cutter and the cutter receiving member so as to provide the most satisfactory cutting effect.
- FIG. 1 is a perspective view showing essential portions of a prior art apparatus for cutting a sheet material.
- FIG. 2 is a schematic perspective view in explanation of the cutting operation of the apparatus according to this invention.
- FIG. 3 is a plan view of FIG. 2;
- FIG. 4 is a side view of FIG. 2 as seen from the side on which the annular cutter is disposed, with the sheet material shown in FIG. 2 being omitted;
- FIG. 5 is a front view showing the relative positions of the annular cutter and the cutter receiving member
- FIG. 6 is a plan view of one embodiment of the cutter receiving member used for cutting a sheet material while the latter is moved;
- FIG. 7 is a side view of the apparatus for cutting a sheet material comprising one embodiment of this invention.
- FIG. 8 is a side view of FIG. 7 showing the annular cutter being made ready for performing a sheet material cutting operation in its starting position;
- FIG. 9 is an enlarged sectional view taken along the line A-A of FIG. 8;
- FIG. l0 is a plan view showing a portion of FIG. 7;
- FIG. 1 1 is a perspective view of means for supporting the annular cutter
- FIG. 12 is a perspective view of one embodiment of the drive means for moving the annular cutter in reciprocating motion.
- annular cutter 4 is firmly fixed, by a clamping nut 8, to the outer circumferential surface of a cylindrical member 7 which includes a slightly convex outer circumferential portion 7a (See FIG. 9).
- Fitted in the bore of the cylindrical member 7 is an outer race of a ball bearing which is secured to the inner wall of the cylindrical member 7 by means of a threaded ring 10 threadably received in the outer opening of the cylindrical member 7.
- the ball bearing comprises an inner race 9b which is threadably connected, by means of a headed screw 13, to the outer end of a shaft 12 which is loosely fitted, at the inner end, in an opening formed in a spherical member 11.
- a headed screw 13 to the outer end of a shaft 12 which is loosely fitted, at the inner end, in an opening formed in a spherical member 11.
- the spherical member 11 supporting the inner end of the shaft 12 is firmly held between a pivotal plate 16 pivotally connected by a shaft 15 to a first side wall 14a of a sliding member 14 and a keep plate 18 firmly fixed at opposite ends to the pivotal plate 16 by means of two screws 17, 17. Since the inner end of the shaft 12 is supported by the spherical member 11, it is posible to adjust the direction of the center axis of rotation of the annular cutter 4 so as to provide the most satisfactory sheet cutting effect. The direction in which the shaft 12 is disposed can be adjusted by slightly loosening the screws 17,17 to provide latitude for rotation of the spherical member 11.
- the shaft 12 which is coaxial with the center axis of rotation of the annular cutter 4 is inclined slightly at a minute angle with respect to a perpendicular to a lateral surface 50 of a cutter receiving member 5 so that a sharp wedgeshaped space S may be formed between the lateral surface 5a and the peripheral edge of the annular cutter 4 as shown in FIG. 3.
- the cutter receiving member 5 is mounted on the upper part of one side of a rigid supporter 20 fixed to an immovable frame of the apparatus and caused to press thereagainst by a bent lateral edge 21a of a keep plate 21 which is attached to the one side of the supporter 20 by a number of screws 22,22.
- the bent lateral edges 21a and 21b straddle the cutter receiving member 5 and its supporter 20, so that the cutter receiving member 5 bears strongly against the supporter 20 and is fixed thereto when the screws 22,22 are tightened.
- the cutter receiving member 5 has an upper end surface 5b which is substantially on the same level as a planar upper surface 200 of the supporter 20.
- the convex outer circumferential portion 7a of the cylindrical member 7 moves in rolling motion on the planar upper surface 200 of the supporter 20 during the process of cutting a sheet material by the annular cutter 4 in cooperation with the cutter receiving member 5.
- the convex outer circumferential portion 7a serves to cause the sheet material to press against the planar upper surface 200 of the supporter 20 and to keep constant the amount of overlapping of the annular cutter 4 and cutter receiving member 5.
- a second side wall 14b of the sliding member 14 to which the pivotal plate 16 is pivotally connected (See FIG. 11) is formed with an opening 23 and a cutout 24, and a third side wall 14c thereof of smaller width is formed with an opening 25 which is aligned with the opening 23.
- a first guide rod 26 loosely extends through the cutout 24, and a second guide rod 27, which is parallel to the first guide rod 26, loosely extends through the aligned openings 23 and 25 (See FIG. 12).
- the sliding member 14 is adapted to move in sliding motion over the guide rods 26 and 27 which are secured at opposite ends to the immovable frame of the apparatus.
- bearings providing a friction reducing effect are mounted in the openings 23 and 25 and cutout 24 for joumalling the guide rods 26 and 27 to prevent the openings and cutout from coming into direct contact with the guide rods, so that the sliding member 14 may be able to move smoothly over the guide rods 26 and 27.
- FIG. 7 shows the wire 29 as it is pulled to the left
- FIG. 8 shows the wire 29 as it is begun to be pulled to the right. Ifthe wire 29 is pulled to the left, the pivotal plate 16 will be moved in pivotal motion in an anticlockwise direction about the shaft till its vertex 16a abuts against a projection 14d formed in the sliding member 14. As the pivotal plate 16 is moved as aforementioned, the annular cutter 4 is released from engagement with the cutter receiving member 5. Since the annular cutter 4 is normally biased outwardly by the spring 19 (See FIG.
- the annular cutter 4 tends to be disposed above the cutter receiving member 5 when the former is released from the latter as shown in FIG. 7.
- This tendency is prevented by a pusher plate 30 mounted in a position in which it is juxtaposed to the outer end of the cylindrical member 7.
- the pusher plate 30 extends to be increasingly spaced apart from the outer end of the cylindrical member 7, so that when the cylindrical member 7 moves in rolling motion from the right in FIG. 10 the pusher plate 30 receives and stops the cylindrical member 7.
- the pusher plate 30 includes a downwardly extending portion 304 which is fixed to the rear side of the supporter 20 by means of screws 31,31.
- the pusher plate 30 is disposed at one end of the supporter 20 which is a starting position of the annular cutter 4.
- the wire 29 is attached at one end to a pulley 32 of relatively larger diameter and at the other end to a peripheral groove of a pulley 33 of substantially the same dimension as the pulley 32.
- the wire 29 is trained over intermediate pulleys 34 and 35 of smaller diameter so as to maintain the length of wire between the two intermediate pulleys 34 and 35 parallel to the guide rod 27.
- the intermediate pulleys also serve to guide the wire 29 so that the opposite ends of the wire are directed to the respective larger diameter pulleys.
- a length 29a of the wire 29'clisposed between the intermediate pulley 34 and larger diameter pulley 32 and a length 29b of the wire 29 disposed between the intermediate pulley 35 and larger diameter pulley 33 are inclined in opposite directions.
- the larger diameter pulleys 32 and 33 are secured to opposite ends of a pulley shaft 37 having a gear 36 mounted near one end thereof which gear 36 is adapted to be oscillated by suitable drive means (not shown) without making a complete revolution in either direction.
- Means for reversing the direction of movement of the gear 36 may be of any suitable type available.
- Such means may include a microswitch disposed in a position in which the sliding movement of the sliding member 14 comes to an end, which microswitch is actuated when a portion of the sliding member is brought into contact with the actuating member of the microswitch so as to reverse the direction of rotation of the electric motor.
- a clutch of a conventional type may be used to change the directions of movement of the sliding member.
- pivotal plate 16 If the pivotal plate 16 is pulled and moved in an opposite direction by the wire 29 after the sheet material is cut, the pivotal plate 16 will be moved in pivotal motion about the shaft 15 and its vertex 160 (See FIG. 7) will abut against the projection 14d before the sliding member 14 pivotally mounting the pivotal plate 16 is pulled and moved, and then the pivotal plate 16 and sliding member 14 will be pulled and moved in the opposite direction as a unit. when the sliding member 14 is restored to a position shown in FIG. 7, the sliding member 14 produces a command to shut off the wire driving means. During the return movement of the pivotal plate, the annular cutter 4 is maintained in a position in which it is spaced apart from the cutter receiving member 5.
- one edge of the cutter receiving member 5 has only to be inclined relative to a line drawn across the width of the sheet material 39.
- the rate of movement Vp of the sheet material, the linear velocity Vc of the annular cutter 4 moving along the inclined edge of the cutter receiving member 5 and the angle of inclination 0 of the edge of cutter receiving member 5 can be expressed by the following formula:
- the material of the cutter receiving member is of higher hardness than the material of the annular cutter. If the annular cutter is caused to press against the cutter receiving member with a relatively great force, the sheet material can be cut easily even if an upper edge 5c of the cutter receiving member 5 is worn and rounded as shown in FIG. 5.
- the old and worn cutter receiving member 5 can be readily replaced by a new one by loosening the clamping screws 22,22.
- the old and worn annular cutter 4 can be readily replaced by a new one by removing the screw 13 threaded into the shaft 12 (See FIG. 9).
- the cutter receiving member may conveniently be in the fonn of a web having a greater length than the effective length of the cutter receiving member. This permits to obviate the time-consuming operation of replacing the worn cutter receiving member by a new one, because the web can be pulled in one direction to bring a new portion into engagement with the annular cutter when the portion of the web serving as a cutter receiving member is worn.
- the material of this web-like cutter receiving member is highly resilient, as in the case with the material of the coiled spring of a clock, because it is convenient to handle, since it can be wound in convolutions at opposite ends of the portion of the web used as a cutter receiving member.
- annular cutter If the annular cutter is not released from engagement with the cutter receiving member when the former is returned to its starting position or if the annular cutter can be moved in reciprocating motion while being maintained in pressing engagement with the cutter receiving member, then it is possible to cut a sheet material by the annular cutter in both its advance movement and its return movement. If a disc is used as a cutter receiving member and the annular cutter is caused to press against its peripheral edge, then it is possible to cut a sheet material in the circular form.
- Means for driving the annular cutter in this case may include a rotary shaft axially extending through the center of the disc and mounting an arm which supports the annular cutter. It will be evident to one having an ordinary skill in the art that the annular cutter can be used in many different ways within the scope of the present invention.
