Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a paper cutting device for an automatic drawing machine that uses continuous, longitudinal drawing paper.

[Conventional technology]

In an automatic drawing machine that uses a roll of drawing paper to cut the drawing paper horizontally into predetermined dimensions and sends it out, the horizontal cutter is controlled based on a barcode signal provided on the drawing paper. The cutting device for cutting into specified dimensions was developed in Japanese Patent Application Laid-open No. 1983-
No. 164191. In addition, a cutting device that uses a horizontal cutter and a vertical cutter to cut paper in a direction perpendicular to and parallel to the feeding direction was developed in Japanese Patent Laid-Open No.
It is disclosed in Publication No. 164192.

[Problem that the invention attempts to solve]

The drawing sheets cut by the cutting device are sequentially discharged from the discharge section. However, after completing the drawing,
It becomes necessary to sort unnecessary cut sheets from a large number of cut sheets accumulated in the storage section. conventionally,
This work was done manually, but it was extremely cumbersome and time-consuming.

The present invention aims to eliminate the above defects.

[Means to solve problems]

In order to achieve the above object, the continuous longitudinal drawing paper is cut into predetermined areas by controlling a horizontal cutter and a vertical cutter based on a detection signal provided for each predetermined area. In the apparatus, swinging guides having dimensions corresponding to the minimum cutting dimension of the paper are arranged in parallel at the feed guide end of the drawing paper, and the swinging guides are selectively controlled to rise and fall according to the signal, The paper is divided into necessary and unnecessary parts.

[Effect]

A plurality of swing guides arranged in parallel at the end of the paper guide of the cutting device each have different paper guide directions in a lowered state and a raised state. By selectively controlling the vertical movement of these swing guides based on signals provided on the drawing paper, cutting paper sent from the cutting device can be automatically separated into unnecessary and necessary paper. It is something that can be done.

Next, the operation of this embodiment will be explained.

In FIG. 2, when the recording paper 4 passes over the recording head 8 while being pressed by the pad roller 10,
An electrostatic latent image made up of tiny dots of static electricity is recorded on the recording paper 4, and when this electrostatic latent image passes through the phenomenon device 12, toner is attached to it and it becomes a visible image. When a figure is recorded on the recording paper 4 by the recording head 8, barcodes 48 are recorded on both sides of the recording paper. One of the pair of barcodes 48 is for a synchronization signal, and the other barcode 48 is made up of barmarks for checking and barmarks for controlling various devices. In FIG. 4, on the recording paper 4, a drawing is recorded in an area S1 over the entire width, and a drawing is recorded in an area S2 on the left half of the recording paper 4. In the right half of the recording paper 4, there is formed a portion where drawings are not recorded, that is, an unnecessary area S3. The recording paper 4 is cut across the transverse lines L1, L2, L by the horizontal cutter 38.
3 along the vertical lines L4, L by the vertical cutters 72, 74, 68.
5, is cut along L6, and further the required area S1,
S2 and an unnecessary area are automatically separated based on the barcode signal, and the necessary areas S1 and S2 fall into the drawing storage container 98, and the unnecessary area S3 falls into the garbage container 10.
Fall to 0. This operation will be explained mainly with reference to FIGS. 1 and 6.

The recording paper 4 is fed on the paper guide 22 to the left in FIG. 1 by a feed roller. When the barcode 48 corresponding to the area S1 of the recording paper 4 is detected by the sensor 44, the code valid/invalid judgment circuit 104 checks the barcode 48 on one side to determine whether the input signal is a barcode. Judging from the mark and the synchronization signal of the barcode 48 on the other side, if it is determined that the input signal is a barcode signal and not a signal due to dirt on the drawing, etc., an operation signal is sent to the timing circuits 104, 106, and 108. At the same time, a barcode detection signal is supplied to the code determination circuit 114. After the barcode 48 is detected, when the recording paper 4 is fed a predetermined amount, the timing circuit 106 operates to stop the pulse motor 32, and the timing circuit 108 operates to supply a motor drive command from the driver to the motor 40. The horizontal cutter 38 rotates once and the recording paper 4 is cut along the line L1. On the other hand, the vertical cutters 76 and 78 on both sides of the recording paper 4 are maintained at the raised position based on the signal from the bar code 48. When the recording paper 4 is cut from the line L1, the pulse motor 32
At the same time as the motor starts driving, the electromagnetic clutch 28 is released. As a result, the feed rollers 52, 54
As a result, the cut recording paper portion S4 is fed to the left in FIG. 4, and when the feed roller 26 is stopped, feeding of the portion of the recording paper 4 including the area S1 is stopped. Next, when a predetermined period of time has elapsed, the timing circuit 104 engages the electromagnetic clutch 28, causing the feed roller 26 to rotate.
The recording paper 4 is fed to the left in FIG. At this time, the vertical cutters 76 and 78 are in the raised position, and the vertical cutter 68 is in the lowered position. Vertical cutter 7
6 and 78 cut both side portions of the recording paper 4 along lines L4 and L5. Next, area S2,
When the barcode 48 of S3 is detected by the sensor 44, after a predetermined period of time, the electromagnetic clutch 28 is released and the feed roller 26 is stopped, and the horizontal cutter 38 is operated to cut the recording paper 4 along the line L2. be done. Barcode 48 corresponding to areas S2 and S3 includes a signal for selecting vertical cutters 76 and 68, and this signal is sent to code determination circuit 114.
judged by. This code judgment circuit 114
Based on the output signal, the timing circuit 110 energizes the solenoid 72 when the tips of the regions S2 and S3 are located directly above and in front of the vertical cutters 76 and 78. As a result, the swing arm 66 rotates in the counterclockwise direction to a predetermined stop position in FIG. 1, and the vertical cutter 68 rotates and projects upward from a vertical slit (not shown) in the paper guide 22.
Note that the solenoid 80 is kept energized, and the vertical cutter 76 is kept protruding above the paper guide 22. At the same time as the vertical cutter 68 rises,
The vertical cutter 78 descends and is drawn below the paper guide 22. In this state, when the recording paper 4 is fed to the left in FIG.
8, lines L5 and L6 are cut. When the next barcode is detected by the sensor 44 in the manner described above, the recording paper 4 is cut by the horizontal cutter 38 along the line L3. of area S1,
When one end of the cut recording paper 4 reaches near the terminal end 22a of the paper guide 22, the swing guide plate 8
6 and 88 are set at predetermined positions based on the barcode 48. That is, the swing guide plates 86, 88
are set in the lowered state by energizing the solenoids 84 and 90, and their tips are connected to the paper guide 2.
2, as shown by the solid line in FIG. Note that when the front area S4 is the drawing execution area, the solenoids 84 and 90 are in the energized state, so this state is continuously maintained. In this state, when the recording paper portion in area S1 is fed to the left in FIG. 1 by the feed roller 54,
The recording paper portion is guided by the swing guide plates 86, 88 and the guide plate 92, and is dropped and stored in the drawing storage container 98. Next, when the leading edge of the recording paper portion in areas S2 and S3 reaches near the end of the paper guide 22, the timing circuit 110 operates based on the output signal from the code determination circuit 114, and the output shaft of the rotary solenoid 90 rotates counterclockwise in FIG. 1, and the tip of the swing guide plate 88 rises to a predetermined stop position. At this time, the swing guide plate 86 maintains the lowered/sheet guiding position. In this state, when the recording paper portions in areas S2 and S3 are moved to the left in FIG. The unnecessary recording paper portion in the area S3 passes through the guide plates 94 and 96 and is stored in the waste container 10.
It falls and is stored inside 0. Vertical cutter 7 for recording paper 4
The portion cut by 6 and 78 is the guide plate 9
2 falls onto the guide plate 96 through the notches 92a and 92b formed on both sides of the garbage container 100, and then falls into the garbage container 100. In addition, vertical cutter 76,7
The cutting of the recording paper 4 by 8 is for removing the barcode recorded portion. Therefore, there is no need to remove the barcode from unnecessary areas of the recording paper, so in that case, the sides of the recording paper where the barcode is recorded are not cut. Further, in this embodiment, an example in which three vertical cutters are provided has been described, but if it is desired to further divide the recording paper into smaller pieces, it is possible to further add a vertical cutter and a swing guide. These vertical cutters and swing guides are driven and controlled based on barcode signals recorded on the recording paper, and each area of the recording paper is divided into necessary and unnecessary parts, and guided to the corresponding storage location. It is something that can be done. Furthermore, in this embodiment, the recording paper is divided into unnecessary parts and necessary parts.
Depending on the size of the cutting area, necessary parts of the same size may be divided, and the parts of the same size may be stored in the same container.

〔effect〕

As mentioned above, the present invention controls the swinging guide plate based on the barcode of the recording paper, and separates unnecessary and necessary parts of the recording paper so that they can be stored in predetermined locations. After cutting, there is an effect that the labor of manually classifying the cut portion into necessary parts and unnecessary parts can be saved.
