Description

cutting machine

The present invention relates to a cutting machine required for cutting thin sheets of paper or the like.

Conventionally, by moving the slider holding the rotating blade forward and backward (forward, backward) on a rail fixed at a predetermined height position, the paper placed on the base is moved by the contact between the rotating blade and the base. Cooperative operation can be cut, and the cutting machine of this kind of structure is known (for example, refer to patent document 1).

The rotating blade held on the slider must adopt an appropriate height position for cutting the stacked paper when moving forward and backward along the track. Therefore, the rotating blade held on the slider is plucked in the direction of the paper to be cut (that is, the direction of the substrate) by the spring, and is constructed so that when it climbs on the paper, it will resist the plucking force of the spring. Can move upwards. Assuming that the rotary blade that cannot move up and down is placed at a position that is too low relative to the laminated paper to be cut, the rotary blade cannot climb up to the upper side of the laminated paper, As a result, the slider cannot move.

The slider supported on the track is held on the rotating blade of the slider every time it performs a forward operation or a backward operation, and climbs onto the layered paper to move the paper from the upper side to the lower side Cut off the set number of sheets each time (the number of sheets corresponding to the tension of the spring).

At this time, the rotating blade that is flicked downward by the spring will gradually descend toward the base body every time the slider is moved forward or backward.

That is, at the time of the first paper cutting operation (for example, advancing operation of the slider), the rotating blade held on the slider cuts the upper layer of the stacked paper. Therefore, the rotary blade is attached to the upper layer of the laminated paper and is in a state of being moved higher than the lower limit position. At this time, the spring system that plucks the rotating blade downward is strongly compressed along with the upward movement of the rotating blade, so that the required initial spring force for pushing the rotating blade to the paper can be brought into play.

Once the first paper cutting operation is completed, the cutting position of the paper caused by the rotating blade will gradually move to the lower layer side. As a result, the spring train that is provided between the rotating blade and the slider body is stretched more than when the paper is cut for the first time, causing the elastic spring of the spring to move when the paper is cut for the second time. The elastic system is more attenuated than in the first paper cutting operation.

That is to say, in the prior cutting machine, in order to cut the stacked sheets of paper, each time the forward movement and the backward movement of the slider are repeated (the paper cutting operation is the first time, the first time, the first time, etc.) The second, the third time......When each time in sequence), the spring force used to push the rotating blade to the paper will gradually weaken, resulting in the number of sheets that can be cut off. decrease drastically.

Therefore, in the conventional cutting machine, especially when the number of stacked sheets of paper to be cut is large, it is necessary to increase the number of repetitions of the forward movement and the backward movement of the slider. For the operator, the advance and retreat operation of the slider will give the impression that it is troublesome.

As a reference example, if the case of cutting 40 stacked sheets of paper using a conventional cutting machine will be specifically described, it will be as described in a.~d. below.

a. In the first advance operation of the slider which is equivalent to the paper cutting operation, since the most compressed spring is utilized to cut the paper, fifteen sheets of paper can be cut.

b. In the second backward operation of the slider which is equivalent to the paper cutting operation, since the paper has to be cut by the pulling force of the spring which is weaker than the first time, it can only be cut Twelve sheets of paper, which are less than the number at the time.

c. In the third advancing operation of the slider which is equivalent to the paper cutting operation, since the paper has to be cut off by the pulling force of the spring which is weaker than the second time, it can only be cut than the second time. Eight sheets of paper with a small number of sheets.

d. In the fourth backward operation of the slider equivalent to the paper cutting operation, since the paper has to be cut off by the pulling force of the spring weaker than the third time, it can only be cut off than the third time. Five sheets of paper with a small number of sheets.

According to the previous example described in a.~d. above, in order to completely cut off the forty sheets of paper that have been stacked, it is necessary to perform the forward operation and the backward operation of the slider twice (that is, Two reciprocating) to do.

Note that the above is the same even when the cutting target of the cutter is a sheet other than paper, and the same is true when the slider has a blade other than the rotating blade. [Prior Art Literature] [Patent Document]

That is, the basic operation of the slider F to cut off a plurality of stacked sheets of paper P is to place the hand (palm) on the slider supported by the track B of the lower position (D). Above F, a load is applied to the slider F in the front-rear direction, and it is executed.

On the other hand, the supporting mechanism R can be moved by rotating the operating end of the operating body K upwardly, which is a direction different from the basic operation of the slider F, by the user's fingers.

That is, the operation for actuating the supporting mechanism R is performed by an operation method clearly different from the basic operation required for cutting the paper P. FIG. Therefore, the slider F disclosed in this embodiment can avoid confusion between the operations required to actuate the supporting mechanism R and the basic operations, and allow the user to easily perform operations at any time sequence.

More specifically, the supporting mechanism R is a rotatable operating body K supported on the slider body G; The spring base H that moves below; and the blade holding structure J that is supported by the slider body G to be movable up and down and has a rotating blade 61 and is disposed below the spring base H through the spring S as the main body, are constitute.

The operation of the support mechanism R will be described with reference to FIGS. 18 to 21 . In addition, FIG. 20 is a schematic diagram corresponding to FIG. 18 . Fig. 21 is a schematic diagram corresponding to Fig. 19 .

First, the user moves the operating end of the operating body K pivotally supported on the slider main body G upward. The operation of the operating body K by the user is performed at an arbitrary timing. That is, when the user operates the slider F in one direction (forward operation or backward operation), and wants to cut a relatively large amount of paper P at one go, the user operates the operation body K.

Once the operating end of the operating body K is rotated upward, the rotating end of the operating body K, which is the pushing portion 73 , pushes the pressed portion pa of the spring base H downward. At this time, the spring base H is pushed downward by the pressing portion 73 , and as a result, it descends against the pulling force of the spring S in the holder main body 21 .

As the spring base H descends, the spring S, which is arranged under the spring base H, is gradually compressed between the spring base H and the blade holding structure J.

The rotating blade 61 of the blade holding structure J obtained by the compressed spring S to obtain the downward pulling force can make the stacked paper P easier than usual (without operating the supporting mechanism through the operating body K). In the case of R action), the elastic force should be stronger while pushing and cutting.

Next, an example of cutting the stacked plurality of paper sheets P using the cutter A of this embodiment will be described.

First, a plurality of sheets of paper P to be cut are placed on a predetermined position on the placement surface m of the base A. Basically, the paper P is positioned on the base by abutting the front edge or the rear edge of the plurality of sheets P to be cut against the rear end edge of the front base portion a2 or the front end edge of the rear base portion a3. On the body a1.

Next, the track B is moved from the upper position (U) to the lower position (D), and the track B is fixed at the lower position (D) by the track locking mechanism L. As the rail B moves from the upper position (U) to the lower position (D), the slider F supported on the rail B moves to a predetermined height position where the paper P can be cut.

In addition, by moving the track B from the upper position (U) to the lower position (D), the paperweight C supported on the base A will be pushed downward by the pusher ps provided on the track B , the paperweight C is in a state where the paper P is pushed from above.

Next, the stacked plural sheets of paper P are cut by repeating one-way operation of the slider F, that is, the forward operation and the backward operation, while actuating the support mechanism R as necessary.

Hereinafter, as a specific example thereof, a case where forty stacked sheets P are cut will be described. (In addition, for the description of the previous example of cutting the stacked forty sheets of paper P, refer to a. to d. of the prior art in this specification.) a. In the first advancing operation of the slider F corresponding to the paper cutting operation, since the most compressed spring force is used to cut the paper P, fifteen sheets of paper P can be cut.

b. In the second retraction operation of the slider F, which is equivalent to the paper cutting operation, usually, the paper P is cut by the pulling force of the spring S which is weaker than the first time, so only Twelve sheets of paper P which are fewer than the first time are cut. Then, in the second retraction operation of the slider F corresponding to the paper cutting operation, the support mechanism R is actuated by any operation of the operation body K by the user, and the force of the spring S is supplemented. Pull the spring. In this way, in the retreat operation of the slide device F equivalent to the paper cutting operation for the second time, the rotating blade 61 can obtain the pulling force caused by the spring S that is equal to the first time, and can cut off the first time. The same number of sheets is fifteen sheets of paper P.

c. In the third advancing operation of the slider F, which is equivalent to the paper cutting operation, usually, the paper P is cut by the pulling force of the spring S which is weaker than the first and second times. , so only eight sheets of paper P that are less than the number of the second time can be cut. Then, in the third advancing operation of the slider F corresponding to the paper cutting operation, the supporting mechanism R is actuated by any operation of the operating body K by the user, and the force of the spring S is supplemented. Pull the spring. Thereby, in the advancing operation of the slider F equivalent to the paper cutting operation for the third time, the rotating blade 61 can obtain the pulling force caused by the spring S equal to that of the first time, and the remaining sheets can be cut off. The number is ten sheets of paper P.

According to the embodiment described in a.~c. above, in order to cut off all the forty sheets of paper P that have been laminated, it is only necessary to perform the forward operation of the slider F twice, and the slider F The retreat operation of F can be done once (that is, 1.5 back and forth). That is, if compared with the previous example, it is obvious that if it is the cutting machine disclosed in this embodiment, it can reduce the time required for the forward and backward operation of the slider F required to cut off the stacked plural sheets of paper P. frequency.

In addition, as a matter of course, the specific example described above is only an example of operation for the convenience of explanation. For example, the support mechanism R may be actuated during the first paper cutting operation. Also, when the number of sheets P to be cut is small, it is of course not necessary to actuate the support mechanism R.

As explained above, the cutting machine according to the present embodiment is provided with: a substrate A on which the paper P corresponding to the sheet of the cutting object is arranged; and the upper position (U) that is further away from the lower position (D) is supported as a movable track B; The slider F corresponding to the rotating blade 61 of the cutting blade is cut. Then, the slider F is provided with: a slider body G mounted on the rail B; and a blade holding structure J having a cutting blade disposed on the slider body G via a spring S ; And be provided with: the spring S that will hold the structure body J downward and dial the spring S; Therefore, it is possible to provide a cutting machine that can ideally suppress the inconvenience that the number of sheets P that can be cut is reduced every time the slider F is moved forward and backward.

The slider F is equipped with: a spring base H that supports the slider body G so as to be movable up and down; The blade holding structure J is arranged. Therefore, since the spring S can be compressed by making the spring base H, the degree of freedom in designing the support mechanism R is better.

The supporting mechanism R is provided with an operating body K that is relatively movable relative to the slider main body G and that allows the spring S to be indirectly compressed through the spring base H. Therefore, the supporting mechanism R can be operated ideally by operating the operating body K.

The support mechanism R includes: an operating body K rotatably supported by the slider body G; and a spring S that can be compressed by rotating the operating end of the operating body K upward. Therefore, the support mechanism R can be actuated by operating the operating end in a direction different from the direction in which the slider F is basically operated for cutting the paper P. That is, with such a configuration, an ideal configuration can be adopted in which the support mechanism R can be actuated by an arbitrary operation by the user.

The slider body G is equipped with: a base 1 having a rail holding portion 11 holding the rail B; Holder 2. Therefore, it is possible to provide the slider F having an ideal configuration with good maintainability and the ability to replace the rotary blade 61 .

The slider F is equipped with: a spring base H that supports the slider body G so as to be movable up and down; The configured blade holding structure J; the retainer 2 can hold the spring base H, the spring S, and the blade holding structure J. Therefore, it is possible to provide the slider F having an ideal configuration with good maintainability and the ability to replace the rotary blade 61 .

The holder 2 is provided with: an upper restricting wall 221 capable of restricting the upper limit position of the spring base H; and a lower restricting wall 222 capable of restricting the lower limit position of the blade holding structure J. Therefore, the spring base H and the blade holding structure J constituting the supporting mechanism R can be positioned at appropriate positions.

The support mechanism R is equipped with: the operating body K that supports the slider body G to be relatively movable and allows the spring base H to move downward; on the upper part of the spring base H, there is: The pressed portion pa that is pressed downward; the pushed portion pa is arranged between the upper restricting walls 221 that are arranged in a pair. Therefore, the operation body K can ideally press the pressed portion pa provided on the spring base H downward.

The track B can be fixed against the base A in the lower position (D). Therefore, the slider F can be located at a position suitable for the substrate A, and cutting of the paper P using the supporting mechanism R can be ideally realized.

The cutting blade system is a rotating blade 61 having a blade edge 612 on the edge. Therefore, since the rotary blade 61 can rotate on the paper P to be cut, the forward operation and the backward operation of the slider F can be performed smoothly.

In addition, the present invention is not limited to the embodiments described in detail above.

The support organization can take various forms, and is not limited to those disclosed in the above-mentioned embodiments.

In the above-mentioned embodiment, although the operation on the operating body is performed by an operation method different from the basic operation required for cutting the paper, the aspect is not limited to that disclosed in the above-mentioned embodiment. For example, the operation end of the operation body may be rotated to the left and right, and the spring base may be lowered by pressing a button.

A slider F according to another embodiment will be described with reference to FIGS. 22 and 23 . In addition, in the same figure, the same code|symbol is used for the structure which is the same as or equivalent to the said embodiment, and description is abbreviate|omitted.

The slider F shown in Fig. 22 is applied to a cutting machine. The slider F is provided with an operation handle K' supported by the base 1 constituting the slider main body G so as to be movable back and forth. The operating handle K' is configured to move back and forth between a front position (F) and a rear position (R). Between the operating handle K' and the spring base H is disposed a pressing member Z that is independent from the operating handle K'. Then, once the operating handle K' moves from the front position (F) to the rear position (R), the pushing member Z will be guided by the inclined surface sl of the operating handle K' to move downward, so that the spring base H can be moved downward. push. The slider F shown in Fig. 22 moves the operating handle K' forward with respect to the base 1 in conjunction with the forward operation, and moves the operating handle K' backward in conjunction with the backward operation. Therefore, when the slider F shown in the same figure is operated backward, the supporting mechanism R will automatically operate. Even so, the desired purpose can still be achieved.

The slider F shown in Fig. 23 is provided with an operation handle K' supported by the base 1 constituting the slider main body G so as to be movable back and forth. The operating handle K' is configured to move back and forth between a front position (F) and a rear position (R). A pressing member X is arranged between the operating handle K' and the spring base H. As shown in FIG. The pushing member X shown in FIG. 23 is arranged such that the front end x1 is rotatably supported by the slider body G, and the rear end x2 is guided by the guide inclined surface sl of the handle K'. s position. Then, once the operating handle K' moves from the front position (F) to the rear position (R), the rear end x2 of the pushing member X will be guided by the guide inclined surface sl of the operating handle K' to move downward, by The lower end portion x3 of the pressing member X, which protrudes downward, can push the spring base H downward. The slider F shown in Fig. 23 moves the operating handle K' forward with respect to the base 1 in conjunction with the forward operation, and moves the operating handle K' backward in conjunction with the backward operation. Therefore, when the slider F shown in the same figure is operated backward, the supporting mechanism R will automatically operate. Even so, the desired purpose can still be achieved.

The cutting object caused by the cutting machine is not limited to paper, of course, it can also be various sheets.

The track can also be not completely fixed in the lower position, and can also be slightly moved in the lower position. In addition, the track system is set so that it cannot move further downward in the lower position, which is ideal.

Cutting blades are not limited to rotating blades. Any one may be used as long as it can cut the sheet along with the sliding movement of the slider.

The spring system is not limited to coil springs, and various other springs such as reeds and resin elastic bodies can be applied.

The blade holding structure may be in any form as long as it has a cutting blade capable of cutting the sheet. The blade holding structure may not be constituted as a replaceable blade unit.

As for the support mechanism, any configuration is acceptable as long as it can supplement the pressing force of the cutting blade against the sheet.

The support mechanism can also directly supplement the pulling force of the spring. For example, the actuating end that can be moved by the operation of the operating body may be positioned at one end of the spring, whereby the spring can be directly compressed by operating the operating body.

The support mechanism can also be provided separately from the spring, and directly flips the cutting blade or the blade holding structure with the cutting blade to increase the pushing force of the cutting blade on the sheet. For example, it is also possible to directly connect the actuating end that can be moved by the operation of the operating body to the rotating shaft of the rotating blade corresponding to the cutting blade, whereby the operating body can be operated to make the rotating blade push the sheet. Pressure increased composition.
