Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for cutting a sheet in two directions.

[0002]

2. Description of the Related Art Conventionally, printed materials such as business cards have been manufactured by cutting a plurality of printed sheets of paper one by one with a sheet cutting device. The sheet cutting device is a device that cuts a sheet into a preset width or length with a metal cutting blade. The width or length of the cut depends on the blade used.

[0003]

The conventional sheet cutting device is capable of cutting a sheet only in one direction. Therefore, when manufacturing a relatively small-sized printed matter such as a business card, it is necessary to perform two steps of cutting the paper in the vertical direction and cutting it in the horizontal direction, resulting in poor work efficiency.

Further, in the conventional sheet cutting device, in order to change the cutting width or length, it is necessary to replace the blade, and the work efficiency is poor.

The present invention has been made to solve these problems, and an object of the present invention is to provide a sheet cutting device capable of cutting in a plurality of directions. Another object of the present invention is to provide a sheet cutting device that can easily change the cutting position.

[0006]

In order to solve at least a part of the above problems, in the present invention, in a paper cutting device for cutting a paper, a transfer mechanism for transferring the paper, A transport direction cutting mechanism for cutting in the transport direction and an intersecting direction cutting mechanism for cutting the paper in a direction intersecting the transport direction are provided. By thus providing a plurality of types of cutting mechanisms, it is possible to cut sheets in a plurality of directions at once. Also, by using a mechanism that cuts at least one in the transport direction,
There is also an advantage that the sheet can be cut while being conveyed, the size of the apparatus can be reduced, and the work efficiency can be improved. In the present invention, the cross direction cutting mechanism does not have to be single, and may be provided in two or more directions.

Various configurations can be applied to the transport mechanism. For example, as a mechanism having a relatively high conveyance accuracy, a configuration in which a pair of rollers sandwich a sheet and convey the sheet can be applied. At this time, if the roller is driven by a stepping motor, the carry amount can be controlled more accurately. In addition, it is preferable that the conveying mechanism is provided with a guide mechanism that prevents the sheet from being displaced in a direction intersecting the conveying direction, and the guide mechanism is preferably capable of adjusting the width according to the sheet.

The transport direction cutting mechanism and the cross direction cutting mechanism of the present invention are preferably used in combination with a rotary cutting mechanism using a rotary blade and a shear cutting mechanism using a shear blade. By doing so, it is possible to reduce the size of the device as compared with the case of unifying to either one of the systems.

When the rotary cutting mechanism and the shearing cutting mechanism are used in combination, the shearing cutting mechanism is preferably arranged upstream of the rotary cutting mechanism. By doing so, shearing can be performed before cutting by the rotary cutting mechanism. Therefore, it is possible to suppress lateral deviation of the paper and the like caused by the shearing force, and it is possible to accurately shear the paper.

The rotary cutting mechanism may be driven by the same power source as the transport mechanism, but is more preferably driven by another drive source. By doing so, the paper can be accurately conveyed regardless of the cutting speed of the rotary cutting mechanism.

In the paper cutting mechanism of the present invention, when the conveying mechanism is provided with a plurality of pairs of upper and lower conveying rollers, the shearing type cutting mechanism is preferably arranged at a position sandwiched by at least two conveying rollers. . By doing this, 2
It is possible to perform shearing while the tension of the pair of conveying rollers is applied to the paper, and it is possible to improve shearing accuracy.

When the rotary cutting mechanism and the shearing cutting mechanism are used in combination, it is preferable that the conveying direction cutting mechanism is a rotary cutting mechanism and the cross direction cutting mechanism is a shearing cutting mechanism. By adopting such a configuration, both mechanisms can be incorporated in a space-efficient manner, and the device can be downsized.

When the rotary cutting mechanism is applied to the paper cutting apparatus of the present invention, it is preferable that the rotary cutting mechanism is configured as a separate body which can be separated from the main body of the paper cutting apparatus. The power for driving the rotary cutting mechanism is, for example,
This can be realized by providing a rotary plate on the main body side of the paper cutting device, and providing the rotary cutting mechanism with an input plate that receives power by contacting the rotary plate when assembled to the main body. Here, the rotating plate and the input plate also include gears. That is, the rotary cutting mechanism can be easily attached and detached by applying a mechanism for transmitting power without using a power transmission belt or a chain. Therefore,
It is possible to easily change the cutting position and improve maintainability.

In the present invention, the cutting direction of the cross direction cutting mechanism can be set in various ways, but it is practically preferable that the cutting direction is orthogonal to the conveying direction. By doing so, cutting into a rectangle can be easily performed. You can

Since static electricity is generally accumulated on the sheet during cutting, the sheet cutting apparatus of the present invention is provided with a static electricity removing mechanism for removing static electricity on the downstream side of the conveying direction cutting mechanism and the cross direction cutting mechanism. It is preferable.

The above-described features of the sheet cutting mechanism of the present invention can be applied in various combinations as appropriate. Further, the following configuration may be added. For example, a sensor that detects the open / closed state of the cover portion that covers the transport direction cutting mechanism and the cross direction cutting mechanism may be provided, and a safety mechanism that prohibits the operation of the apparatus when the cover portion is open may be provided. A storage unit for storing the finished product after cutting may be provided on the downstream side of the transport direction cutting mechanism and the cross direction cutting mechanism. A collection box for collecting waste paper generated during cutting may be provided.

The present invention can also be configured as a control method of the above-described sheet cutting device. In this case, it is preferable to control so that the cutting is performed by the cross direction cutting mechanism and then the transport direction cutting mechanism.

3b and 73c are an upper cutter 71 and a lower cutter 72.
It is also provided along with the parts that are discarded after being cut into pieces. As a result, after cutting, the finished product can be conveyed as it is to the downstream side, and only the waste paper can be separated and automatically discarded downward.

G. Cutting Control: FIG. 11 is an explanatory diagram showing the state of the paper before cutting. It is assumed that a business card is printed on the paper in a size of horizontal W × vertical T at a position indicated by a frame in the figure. Business cards are printed in two rows of four, with a space V in the horizontal direction and a space D in the vertical direction. Let M be the margin at the top. The number of cut sheets N is 8. The cutting control process will be described by taking as an example the case where this paper is cut into eight business cards.

FIG. 12 is a flow chart of the cutting control process. This is the process executed by the control unit 4. This process is started by the user pressing the start key. When the processing is started, the control unit 4 inputs cutting parameters (step S10). The cutting parameter means each numerical value shown in FIG. These numerical values are set by the user operating the button 31. In this embodiment, since the vertical cutting position is fixed by the vertical cutting mechanism 7, the input of the horizontal width W and the interval V of the business card may be omitted.

Next, the control unit 4 uses the transfer stage 5
It is detected whether or not a sheet is set on the sheet 1 (step S12). If the paper is not installed, a display prompting the user to install the paper is displayed on the display 32 (step S
14).

If paper is installed, the sensor 1
The sheet is carried in until the upper edge of the sheet is detected by 17 (steps S16 and S18). This state corresponds to a state in which the upper end of the sheet has almost reached the transport roller 300.

When the upper end is detected, the control unit 4
The conveyance rollers 300, 400, 600 are driven to convey the sheet to the lateral cutting mechanism 6 (step S20). As described above, the transport rollers 300, 400, 600 are driven by the stepping motor 307. The control unit 4 controls the cutting parameters and the conveyance rollers 300, 4
The driving of the stepping motor 307 is controlled so that the sheet is appropriately positioned below the cutter 62 based on the circumferences of 00 and 600.

When the sheet is conveyed in this manner, the control unit 4 drives the stepping motor 640 to execute cutting in the lateral direction (step S22). When the cutting in the horizontal direction is completed, the conveying rollers 300, 400 and 600 are driven again to convey the paper, and the AC motor 804 is driven to execute the vertical cutting by the vertical cutting mechanism 7 (step S24). The cut finished product is stored in a storage box 100 provided on the back surface, and the waste paper is collected in a waste paper collection box 9 provided at a lower portion. In this way, the control unit 4 repeatedly executes the horizontal cutting and the vertical cutting in parallel until the cutting of the number of cut sheets N is completed (step S26), and the cutting control process is completed.

H. Effect: According to the sheet cutting apparatus 1 of the present embodiment described above, it is possible to perform the horizontal cutting and the vertical cutting, and it is possible to improve the workability. Further, the cutting position by the lateral cutting mechanism 6 is the stepping motor 30.
Since it can be easily changed by the drive control of 7, it is possible to easily deal with the change of the cutting size.

The vertical cutting position can be changed by replacing the vertical cutting mechanism 7. Longitudinal cutting mechanism 7
Since it is configured as an integral mechanism and can be easily replaced, it is possible to relatively easily deal with the change of the cutting position in the vertical direction.

I. Modified Example: In the embodiment, the case where the lateral cutting mechanism 6 cuts in the direction orthogonal to the sheet conveying direction is illustrated. The installation direction of the lateral cutting mechanism 6 does not need to be orthogonal to the transport direction. The present invention can also be configured as a device that cuts a sheet into parallelograms by disposing the lateral cutting mechanism 6 in a direction offset from the orthogonal direction.

In the embodiment, the case where the mechanism for shearing the paper is applied as the horizontal cutting mechanism 6 and the mechanism using the rotary blade is applied as the vertical cutting mechanism 7 is exemplified, but the reverse may be applied. Furthermore, both may be a mechanism by shearing or a mechanism by a rotary blade.

In the embodiment, the case where the horizontal cutting mechanism 6 is arranged on the upstream side of the vertical cutting mechanism 7 is illustrated, but the arrangement of both may be reversed. However, when the mechanism by shearing and the mechanism by rotary blade are used in combination, by arranging the mechanism by shearing on the upstream side, it is possible to suppress the deviation of the paper due to the shearing force and realize the accurate cutting. There is an advantage that can be.

Although various embodiments of the present invention have been described above, it is needless to say that the present invention is not limited to these embodiments and that various configurations can be adopted without departing from the spirit of the invention. For example, the above control processing may be realized by hardware as well as software.
