Description

Cutting machine
Technical Field
The present invention relates to a cutting machine for cutting paper.
Background
Conventionally, there is known a so-called pinch-cut type cutting machine which can cut a sheet of paper placed on a base by cooperation of an upper blade and a lower blade by rotating the upper blade (cutting blade) with respect to the base.
Conventionally, in a press-cutting type cutting machine, an upper blade and a lower blade are pressed by a pressing mechanism capable of restricting relative rotation therebetween. Basically, the cutting machine does not rotate the upper blade and the lower blade relative to each other by the pressing mechanism as long as the user does not directly rotate the upper blade.
On the other hand, since the operation of the upper blade generally depends only on the pressure-contact mechanism, for example, in a case where an unexpected operation force acts on the upper blade due to a collision between a surrounding article or the like and the upper blade, in a case where the upper blade is excessively worn, or in a case where the pressure-contact mechanism is damaged and/or loosened, it is conceivable that the upper blade and the lower blade are relatively rotated regardless of the intention of the user.

The front cover 3 is a synthetic resin member. The front cover 3 is attached to the front end of the base body 1. The front cover 3 includes: an upper wall 31, an inner wall 32 depending from a rear end edge of the upper wall 31, an outer wall 33 depending from a front edge of the upper wall 31, a left side wall 34 connecting between the inner wall 32 and a left side end edge of the outer wall 33, and a right side wall 35 connecting between the inner wall 32 and a right side end edge of the outer wall 33. An upward movement locking claw t for prohibiting the upward movement of the upper blade C when the upper blade C is located at the lower position (S) is provided at the right side wall 35 of the front cover 3. The upward movement locking claw t is rotatably supported by a locking claw support portion 36 provided to protrude from the right side wall 35 of the front cover 3. When the upper blade C is positioned at the lower position (S), the upward movement locking claw t is rotated, and the upward movement locking claw t engages with an engaging convex portion C1 protruding outward from the distal end portion of the upper blade C.
The upper blade C can cut the paper P in cooperation with the lower blade J of the base B. The upper blade C has a flat plate shape extending in the front-rear direction. The upper blade C is a metal member having excellent rigidity. The upper blade C is supported to be rotatable along the lower blade J of the base B. That is, a rear end portion (end portion on the back side as viewed from the user) as a base end portion of the upper blade C is supported to be rotatable with respect to the base B. The upper blade C is configured to be rotatable between an upper position (U) at which the sheet P is disposed between the upper blade C and the lower blade J and a lower position (S) at which the sheet P is arranged in a lateral direction in substantially the same posture as the lower blade J. A grip D that can be gripped by a user is attached to a distal end portion (an end portion on the near side when viewed from the user) of the upper blade C.
The upper blade C is held in a state of being pressed against the lower blade J with a predetermined force by a pressing mechanism w disposed in the rear cover 2. The pressure bonding mechanism w includes: a support shaft w1, the support shaft w1 having an upper blade contact portion w11 at one end thereof, which contacts the outer surface of the upper blade C, and a screw groove mz for nut attachment at the other end thereof; a coil spring sp wound around the support shaft w 1; and two kinds of nuts n1, n2, which are n1, n2, which are screw-engaged with the screw groove mz of the support shaft w 1. The pressure bonding mechanism w causes the upper blade C and the lower blade J to be pressure bonded with a constant pressing force by the biasing force of the coil spring sp disposed between the upper blade contact portion w11 of the support shaft w1 and the nuts n1 and n 2.
The paper presser E is disposed adjacent to the upper blade C and is supported to be rotatable relative to the base B so as to be able to press the paper P disposed on the upward surface m of the base B. The paper pressing piece E has a shape extending in the front-rear direction of the base B along the upper blade C. The paper pressing member E includes a synthetic resin paper pressing member main body 4 and a paper contact pad K disposed on a lower surface side of the paper pressing member main body 4.
The paper sheet pressing body 4 includes: a base end portion 41, the base end portion 41 having a shaft portion 41a engaged with the concave portion 213 of the rear cover 2; a linear portion 42 extending from the base end portion 41 to the front side; and an inner extension 43, the inner extension 43 extending from a front portion of the linear portion 42 to a side opposite to the upper blade C and the lower blade J in a plan view.
The base end portion 41 has a rectangular block shape, and includes an engagement recess 41b on an outer side surface thereof, which engages with the locking claw v1 of the paper pressing member supporting portion 21 b.
The linear portion 42 extends substantially parallel to the upper blade C and the lower blade J in a plan view, and a groove-shaped safety plate attachment portion 42a for attaching the safety plate F is formed on the upper surface. The safety plate mounting portion 42a is formed in a shape recessed in a groove shape as a whole. The safety plate attachment portion 42a has a plurality of convex portions 42b as the other engagement portion protruding forward near the bottom of the groove. The safety plate mounting portion 42a includes a positioning wall 42c that extends in the front-rear direction apart from the convex portion 42 b. The dimension of separation between the protruding portion 42b and the positioning wall 42c is set to be substantially the same as the thickness dimension of the insertion wall 62 of the engagement portion 6 provided on one of the safety plates F.
The inner extension portion 43 includes a lower extension wall 43a substantially parallel to the upward surface m of the base portion B at the paper pressing position, and a rising wall 43B rising from the front end of the lower extension wall 43 a. The paper pressing member body 4 is formed with a portion recessed by the inner extension portion 43 and the linear portion 42. A horizontal piece 44 protruding forward (near side) is provided from the front end edge of the straight portion 42 and the rising wall 43b, and is configured to be held by a finger when the user operates the paper pressing member E.
< safety plate F >
The safety plate F is provided upright on the paper sheet holder E so as to be detachable from the paper sheet holder E. The security plate F is a single member made of synthetic resin, and is set to be transparent or translucent in this embodiment. The safety plate F is attachable to and detachable from the paper holder E without using a fastening tool such as a screw separate from the safety plate F.
The safety plate F includes a plate-shaped safety plate body 5, and a safety plate mounting portion 42a provided at a lower end portion of the safety plate body 5 and engageable with the other engagement portion provided in the paper presser E.
That is, the safety plate F is attached to the paper presser E by engaging one of the engaging portions 6 provided at the lower end of the safety plate F with the safety plate attachment portion 42a provided as the other engaging portion of the paper presser E. In this embodiment, by sliding the safety plate F in the forward direction with respect to the paper presser E, the concave portion 61 provided in one engaging portion 6 of the safety plate F can be engaged with the convex portion 42b provided in the safety plate mounting portion 42a, which is the other engaging portion of the paper presser E. On the other hand, by sliding the safety plate F in the backward direction with respect to the paper presser E, the engagement state between the concave portion 61 provided in one of the engaging portions 6 of the safety plate F and the convex portion 42b provided in the safety plate mounting portion 42a as the other engaging portion of the paper presser E is released.
The security plate body 5 is formed in a trapezoidal shape in side view. The security plate main body 5 includes a lower main body 51 located at a lower portion and an upper main body 52 located at an upper portion. The upper body portion 52 of the safety plate body 5 includes a sloped surface 52a that is sloped so as to gradually separate from the upper blade C as it goes upward. Further, a sloped side 52b is formed at the rear of the upper body 52 in a side view so as to form a substantially same slope angle when adjacent to the upper blade C.
One of the engaging portions 6 includes a plurality of recesses 61 open toward the front, and an insertion wall 62 formed adjacent to the plurality of recesses 61. The safety plate mounting portion 42a, which is the other engagement portion that engages with one engagement portion 6, is provided in the paper presser E, and includes a plurality of projecting portions 42b that project rearward. The insertion wall 62 is inserted between the protrusion 42b and the positioning wall 42c in the safety plate mounting portion 42a of the paper presser E, and functions to maintain the posture of the safety plate F with respect to the paper presser E.
Further, the dimension of the safety plate F in the front-rear direction is set shorter than the dimension of the base B in the front-rear direction toward the upper surface m. Therefore, as shown in fig. 10, in a non-use state in which the safety plate F is not attached to the paper pusher E, the safety plate F can be placed in a state in which the safety plate F is laid on the upward surface m of the base B, and loss can be suppressed.
< rotation inhibiting mechanism G >
The rotation inhibiting mechanism G can set the upper blade C located at the upper position (U) to be stationary (not lowered) by a manual operation based on the intention of the user while the user places the sheet P on the base B. That is, the rotation inhibiting mechanism G restricts the upper blade C from performing an unexpected motion, thereby contributing to the user's reassurance.
The rotation inhibiting mechanism G can inhibit rotation of the upper blade C in one direction, that is, rotation of the upper blade C located at the upper position (U) toward the lower position (S). In other words, the rotation inhibiting mechanism G can inhibit the upper blade C from rotating downward.
In this embodiment, the operating member 7 serving as operating means for operating the rotation inhibiting mechanism G is provided at a position away from the upper blade C. That is, the operation member 7 operated by the user's finger is provided at a position where the paper pusher E is interposed between the operation member 7 and the upper blade C.
More specifically, the rotation inhibiting mechanism G is slidable in the left-right direction between a rotation inhibiting position (L) at which the rotation of the upper blade C is inhibited and a rotation allowing position (R) at which the rotation of the upper blade C is allowed by the user's operation. The rotation inhibiting mechanism G includes an operating member 7 made of synthetic resin and a metal pin Q attached to the operating member 7.
The operation member 7 includes an operation member base 71 and an operation protrusion 72 protruding from the operation member base 71. The rotation prohibiting mechanism G is disposed in the rear cover 2.
The operation member base 71 includes an operation member base body 711 having a rectangular flat plate shape, and a pin support portion 712 provided to protrude from a lower surface of the operation member base body 711 and holding one end portion of the pin Q.
The operation member base body 711 includes a first display region R1 exposed from the window 21a of the rear cover 2 when located at the rotation prohibiting position (L), and a second display region R2 exposed from the window 21a of the cover when located at the rotation permitting position (R). In this embodiment, a color scheme (for example, red or vermillion) that easily arouses the attention of the user is displayed in the first display region r 1.
The pin Q is a rod-shaped member made of metal. The pin Q is configured to be slidable together with the operating member 7 between a rotation prohibiting position (L) where the tip end portion thereof is positioned below the upper blade C and a rotation permitting position (R) where the tip end portion is not positioned below the upper blade C. The pin Q is slidably supported by a channel-shaped guide member 9 attached to the rear wall 15 of the base body 1.
In this embodiment, the pin Q is configured to be able to pass through the through hole a1 provided in the lower blade J having excellent rigidity and to protrude and retract below the upper blade C.
The rotation prohibition mechanism G can perform a restriction stop between the rotation prohibition position (L) and the rotation permission position (R) by the restriction (japanese: temperate) mechanism 8. The stopper mechanism 8 includes: a plate-shaped click plate 81 attached to the lower surface of the operation member base body 711 and having a recessed portion 81a at the front edge thereof, which is separated to the left and right, and a leaf spring member 82 attached to the base body 1 and having a protrusion capable of elastically engaging with the recessed portion 81a of the click plate 81.
As described above, the cutting machine a of the present embodiment includes: a base B having an upward surface m for arranging the sheet P and a lower blade J at a side end; an upper blade C supported to be rotatable along the lower blade J of the base B; and a rotation inhibiting mechanism G capable of inhibiting rotation of the upper blade C in at least one direction, i.e., rotation of the upper blade C toward the lower blade J. The operation member 7, which is an operation unit operated by the finger Y for operating the rotation prohibiting mechanism G, is provided at a position away from the upper blade C. Therefore, it is possible to provide the cutting machine a capable of appropriately suppressing the relative rotation of the upper blade C with respect to the lower blade J regardless of the intention of the user.
That is, since the operating member 7 of the rotation inhibiting mechanism G is provided at a position away from the upper blade C, it is easy for the user to operate the operating member 7 to operate the rotation inhibiting mechanism G as intended. In other words, since the cutting machine a includes the rotation inhibiting mechanism G separately and independently from the pressure contact mechanism w provided conventionally, it is difficult to give the user psychological anxiety as to whether or not the upper blade C is arbitrarily moved with respect to the base B.
The cutting machine a includes a paper presser E disposed adjacent to the upper blade C and supported rotatably with respect to the base B so as to be capable of pressing the paper P disposed on the upper surface m. The operating member 7 is disposed at a position where the paper pressing member E is interposed between the operating member 7 and the upper blade C. Therefore, the operation member 7 is disposed at a position appropriately spaced from the upper blade C, and therefore the user can easily recognize and operate the rotation prohibiting mechanism G.
The rotation inhibiting mechanism G includes an operating member 7 and a pin Q attached to the operating member 7. The tip portion of the pin Q is configured to be slidable between a rotation prohibiting position (L) where the pin Q is positioned below the upper blade C and a rotation permitting position (R) where the pin Q is not positioned below the upper blade C. Therefore, the rotation prohibiting mechanism G can be relatively easily operated by the sliding operation of the operating member 7.
The pin Q of the rotation inhibiting mechanism G is configured to be able to pass through the through hole a1 provided in the lower blade J and to protrude and retract below the upper blade C. Therefore, the pin Q is supported by the lower blade J having excellent strength. That is, even when an excessive force from the upper blade C acts on the pin Q, the lower blade J of the support pin Q has excellent strength, and therefore, a desired rotation inhibiting function can be appropriately exhibited.
The base B includes a base body 1 having an upward surface m, and a rear cover 2 disposed on the rear side of the base body 1 and having a positioning surface 221 against which the upper edge P1 of the paper P can abut. The rotation inhibiting mechanism G is disposed in the rear cover 2. Therefore, the rotation inhibiting mechanism G is disposed in the rear cover 2, which is easy for the user to see and understand.
The operation member 7 includes an operation member base 71 and an operation protrusion 72 protruding from the operation member base 71. The operation member base 71 includes a first display region R1 exposed from the window 21a of the rear cover 2 when located at the rotation prohibiting position (L) and a second display region R2 exposed from the window 21a of the rear cover 2 when located at the rotation permitting position (R). Therefore, by making the first display region R1 and the second display region R2 different in appearance (color, characters, figures, etc.), it is possible to easily visually confirm which of the rotation prohibiting position (L) and the rotation permitting position (R) the rotation prohibiting mechanism G is located.
The present invention is not limited to the embodiments described in detail above.
In the above-described embodiment, the rotation inhibiting mechanism can inhibit only the downward rotation of the upper blade, but the rotation inhibiting mechanism is not limited to this configuration, and may inhibit the upward rotation of the upper blade. For example, the pin of the rotation inhibiting mechanism may be configured to be able to be positioned in a through hole formed in both the upper blade and the lower blade at the rotation inhibiting position.
The operation unit of the rotation prohibiting mechanism may be provided at a position away from the upper blade, but is not limited to the configuration shown in the above embodiment. For example, the operation unit of the rotation prohibiting mechanism may be provided on a side portion of the base portion opposite to the lower blade.
In the above-described embodiment, the rotation inhibiting mechanism can take the rotation inhibiting position located below the upper blade and the rotation permitting position not located below the upper blade by projecting and retracting the distal end portion of the pin from the base portion.
For example, it is conceivable that the rotation inhibiting mechanism includes a rotation member body that is rotatably supported by the base body and extends in the left-right direction, and a distal end regulating portion that is provided continuously integrally with the rotation member body and extends in a direction substantially orthogonal to the rotation member body and can bring the distal end into contact with the lower side of the upper blade. Further, it is conceivable that the rotation member body is rotated to take a restricting position at which the distal end of the distal end restricting portion is brought into contact with the lower edge of the upper blade and downward rotation of the upper blade is prohibited so as to be called a "support rod (つっかえ rod)" and a non-restricting position at which the distal end restricting portion is not brought into contact with the upper blade. Even with such a configuration, the desired object can be achieved. In addition, with this configuration, even when an excessive operating force of a certain level or more is applied to the upper blade, the distal end regulating portion can be forcibly moved from the regulating position to the non-regulating position in order to avoid damage to the member.
The specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention.
