Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention connects a paper winding device to an image forming apparatus such as an electronic copying machine for producing large-sized recording paper, as shown in the drawings, etc. Regarding a device that rolls up a recording paper formed as a wrapping paper by rolling it up in a cylindrical shape, pasting and sealing an adhesive tape, and especially when the operation of the paper wrapping device is disturbed, continue the work as it is The present invention relates to a recording paper processing apparatus of a continuous image forming apparatus, which allows a control device to arbitrarily set whether to suspend work.

[0002]

2. Description of the Related Art In an image forming apparatus such as an electronic copying machine or a laser printer which produces a recording sheet by using an electrophotographic method, a sheet cut into a standard size such as A3 or B4 size is used. Use, according to the size of the original,
Means for selecting a suitable size of paper and creating a recording paper are used. In the electronic copying machine, a plurality of paper feed trays, paper feed cassettes, and the like are housed in a paper feed unit, and paper is selected based on information such as the size of a document and a reduction ratio.
It constitutes a means for feeding paper toward the image forming unit. Then, the recording paper created in the image forming apparatus is fixed through a fixing device and then discharged toward a discharge tray or the like.

Further, in addition to the electronic copying machine using the small size paper as described above, in an electrophotographic copying machine used for making drawings, an image forming apparatus such as a laser printer or a plotter, A0 size is used. Alternatively, recording paper is created using a large size paper such as A1 size. An electronic copying machine will be described as an example of the image forming apparatus for the drawings.
As disclosed in Japanese Unexamined Patent Publication No. 87133, it is possible to mount a wide roll paper on a paper feed unit and cut the paper fed from the roll paper according to the size of the original to create a large size recording paper. A device configured to allow is used.

[0004]

However, the recording paper created by the large-sized electronic copying machine can be discharged as an arbitrary length, but in the conventional electronic copying machine, a long recording paper is used as it is. It is discharged in a continuous state and is deposited as it is on a receiving member such as a large box.
Then, for the long recording paper as described above, it is necessary for the operator to stand by at the recording paper discharge section and perform work such as winding the long recording paper. Therefore, in the conventional electronic copying machine, when a particularly long recording paper is prepared, it is necessary to organize the recording paper so that the recording paper does not scatter at the discharge port of the apparatus. ing.

Using a large-sized original document as described above,
In addition to the case of creating recording paper, in recent large-sized electronic copying machines, an image information output device such as a computer is used.
There is a case in which a mechanism for continuously ejecting a large-sized recording paper is configured according to the image information output from the output device in combination with the electronic copying machine. In an apparatus that connects an output device such as a computer to an electronic copying machine to create a large-sized recording sheet, a plurality of output devices may be connected to one electronic copying machine. Therefore, in response to a recording paper creation command from any output device,
When making recording paper, unless the operator is always standing by the electronic copying machine, the recording paper cannot be sorted and large-sized recording paper is scattered around the electronic copying machine. Occurs.

Therefore, in order to solve the above-mentioned problems, a device for folding a large size recording paper into a standard size is also used. As the sheet folding device, for example, a device configured as shown in JP-A-63-196462 can be used. However, generally, a drawing created using a plotter or the like has originality and is often used for confirmation of a concept check on a recording paper. Therefore, it is not preferable to use the folding device as shown in the above-mentioned conventional example, and there is a problem in post-processing when a large size recording paper is prepared.

Therefore, instead of using the folding device as described above, for example, the actual flat plate 1-149363.
As disclosed in Japanese Unexamined Patent Application Publication No. 2003-242242, it has been proposed to arrange a paper winding mechanism with respect to a discharge tray for discharging recording paper so that the work of checking the recording paper can be performed easily. In the recording paper processing device shown in the conventional example,
By arranging a mechanism for winding the paper at the end of the output tray and holding the long recording paper in a cylindrical shape, it is not necessary for the operator to wind the recording paper during the copying operation. The processing work can be simplified. However, as described above, even when the mechanism for automatically winding a long recording paper is arranged, the recording paper is taken out from the discharge tray every time one recording paper is discharged.
It is required to move to another containment device. In addition, the roll-like recording paper may easily spread to its original state when it is not bound, and there is a problem that it is troublesome to store it thereafter. Furthermore, when continuously producing large-sized recording paper, the operator is required to process a long original and a cylindrical paper each time one recording paper is prepared, which is relatively troublesome. It is necessary to successively perform such operations.

As described above, in the case where the paper winding device is combined with the image forming apparatus to make recording paper at night, the image forming apparatus is operated in an unmanned state and a large amount of recording paper is produced. It is conceivable to configure a device that automatically ejects the paper as a wrapping paper. However, for example, when a large amount of recording paper is output, the label or the like used for sealing is consumed, and there is a case where the wrapping paper cannot be automatically sealed even if a paper winding device is used. On the contrary,
If the label is exhausted within the normal working time, it will be displayed to the operator near by displaying that there is no label on the display of the image forming apparatus and outputting a warning sound. You can easily notify them and take action. However, if the operation of the apparatus is stopped during the unmanned operation at night, it is necessary to perform subsequent recording paper preparation in the next morning, which causes a problem in the recording paper preparation work.

[0009]

It is an object of the present invention to provide an image forming apparatus or a paper winding device to an electronic copying machine for producing large-sized recording paper as described above, when the recording paper is discharged in a sealed state as a wrapping paper. The information input to the control device can be used to automatically select whether to interrupt the work in the event of a non-sealable state or to eject the recording paper that has been wound using the paper winding device. It is an object of the present invention to provide a recording paper processing apparatus of an image forming apparatus configured as described above and adapted to operate the apparatus according to the actual state of the recording paper preparation work.

[0010]

According to the present invention, a wide and large size roll paper is mounted in a paper feed unit of an image forming apparatus, and the paper delivered from the paper feed unit is the size or designation of an original. Create a large size recording paper by cutting it according to the size, connect a post-processing device to the paper discharge section of the image forming apparatus, and arrange a paper winding device in the post-processing device to create a recording paper. Recording paper processing provided with a paper winding device that rolls the formed paper into a predetermined diameter, seals the paper with a sealing means, and discharges the paper as a wrapping paper, and a means that directly discharges the recording paper through a paper guide path of the paper winding device. Regarding the device. In the present invention, when setting the mode of discharging the wrapping paper in the paper wrapping device in the sealed state, even if the wrapping paper cannot be sealed, a wrapping paper discharge system that does not seal the wrapping paper is used. A control means for ejecting the liquid is provided. Further, in the present invention, when a mode in which the wrapping paper cannot be sealed occurs when setting a mode for discharging the wrapping paper in the paper wrapping device in a sealed state, the device is stopped, or It is also possible to provide control means for discharging the unsealed wrapping paper by using the wrapping paper discharge system.

As described above, when the paper winding device is connected to the image forming apparatus and the mechanism for discharging the paper in a sealed state is constructed, when the label used for sealing in the paper winding device is insufficient. However, when there is no operator nearby, the work of winding the recording paper can be continued and discharged to the discharge tray. Further, for example, when the wrapping paper is discharged to the discharge tray without being sealed, the rolled recording paper returns to the unwound state, but it is relatively easy to wind the recording paper later. Is something you can do,
It does not significantly hinder work efficiency. Then, when a large amount of large-sized recording paper is created during unattended operation at night, a large amount of recording paper can be created without interrupting the operation of the apparatus. Furthermore, in the case of setting a control mode for the control device of the image forming device or the paper winding device, in which the operation of the device can be stopped or can be selected in a state where the sealing work cannot be continued, It is possible to easily deal with the condition where the operator is nearby and the condition of unmanned operation, and it is possible to improve the movement efficiency of the device.

[0023]

[Embodiment 3] When the recording paper is directly discharged In the above-described embodiment of the present invention, the recording paper is formed as a wrapping paper. It is possible to directly eject the paper without operating the paper winding device. In order to meet the above purpose, as shown in FIG. 5, a gate member 35 is arranged with respect to the paper winding device 25. The gate member 35 is
It is swingably provided via a support shaft 37, and a gate arm 36 is provided at a lower portion so as to project. The gate arm 36 is configured as an extremely long arm member, and the outer surface of the gate arm 36 has the same curvature as the lower semicircular guide 27. And

So that it is discharged toward the outside of the. In the state shown in FIG. 5, it is also effective to drive the driving roller member arranged in the paper winding device 25 so that the roller members 32 and 33 assist the paper discharging operation.

[0025]

[Embodiment 4 of the control means] The example shown in FIG. 6 schematically shows the apparatus shown in FIG.
The post-processing device 20 is connected to the electronic copying machine 1, and a discharge tray 45 for storing a wrapping paper is provided under the post-processing device 20, and a discharge tray for storing a recording paper which is not subjected to the wrapping process is provided in a downstream portion. 47 are arranged. The post-processing device 20
The paper winding device 2 is similar to that shown in the above embodiment.
5 and the labeler 50 are arranged so as to correspond to the creation of the wrapping paper. An opening / closing gate 46 is disposed below the paper winding device 25. The gate 46 can be configured by a swing arm 30 including a lower semicircular guide 27 as shown in FIG.

In the apparatus shown in FIG. 6, the command from the image information output device such as a computer causes
When a wrapping paper creation command is issued when creating a recording paper, the recording paper is guided to the paper winding device 25 to create a wrapping paper, a label is attached and sealed, and the gate 46 is opened to discharge the lower part. The tray 45 is discharged. Further, when it is not necessary to perform the paper winding process, the recording paper discharged from the electronic copying machine 1 toward the post-processing device is left as it is.
It can be discharged toward the side discharge tray 47.

In the device constructed as described above,
As shown in the flowcharts of FIGS. 7 and 8, a recording paper processing program can be set in the control device so that the operation of the sealing of the wrapping paper can be performed. FIG. 7
In the flowchart shown in FIG. 2, when the switch of the apparatus is turned on, the recording paper creation command is issued in step a-1, and the processing of the recording paper is set to the paper winding mode in step a-2. In step a-3, it is determined whether the labeler can perform the sealing operation. Then, in the step a-3, when the sealing operation cannot be performed, the process proceeds to the step a-4, and a command for interrupting the preparation of the recording paper in the state where the sealing operation cannot be performed. Is output.

In each of the steps a-2 to a-4, for example, when there is an instruction to eject the recording paper without winding it in the step a-2, the process proceeds to step a-5, and the image forming apparatus is operated. The recording paper discharged from 1 is sent directly to the discharge tray. In addition, the a-
In the case where the wrapping paper can be sealed in step 3, the process proceeds to step a-6, the wrapping device 25 of the post-processing device 20 is used to create the wrapping paper, and the sealing by the labeler 50 is performed. With the operation performed, the wrapping paper is dropped on the discharge tray 45 arranged at the lower part of the post-processing device 20. Further, in the step a-4, even if the sealing cannot be performed, if the instruction to process the recording paper is set through the paper winding device, the process proceeds to the step a-7, and the post-processing device Guide the recording paper to the paper winding device of
After the paper-wrapping operation is performed, the paper can be discharged to the lower discharge tray 45 without sealing with the label.

As described above, in the control device provided for the device of the present invention, when it is desired to continue the production of the recording paper even when the labeler cannot perform the normal sealing work, the label sealing is performed. It is possible to set a mode in which the recording paper is ejected without performing. For example,
Even if the post-processing device processes a large amount of recording paper and the label set in the labeler is consumed, or the labeler has an accident and cannot perform the sealing work, the above step a If the mode in which the sealing process is not performed is set in -4, the paper discharge process in the unsealed state can be continuously performed. Therefore, when a post-processing device is combined with the image forming device to create recording paper in an unattended state, even if the labeler fails or the label runs out, the operation of the device is not stopped. , It is possible to continue to create recording paper.

On the other hand, when the operator is nearby, means for setting and setting a sealing prohibition command and outputting a warning signal from the control device are provided in step a-4. You can also In that case, when a state in which the sealing work cannot be continued occurs, the operation of the post-processing device is interrupted and made to stand by. Then, the operator performs work such as inspecting the labeler to recover from the failure,
This makes it possible to take measures so that the work of recording paper can be immediately continued.

In addition to the flow chart shown in FIG. 7, the control mode shown in the flow chart of FIG. 8 can be set in the present invention. In the flowchart shown in FIG. 8, when the label disappears and the signal is output, the operation of the paper winding device is interrupted, and thereafter, even if a predetermined time elapses, the accident recovery process is performed. If not, switch the paper winding mode,
The control mode is set so that the recording paper is ejected without being sealed. In the flowchart of FIG.
In step b-1, it is determined whether or not the labeler can handle the sealing work, and if the sealing work can be performed, the sealing paper work is continued in step b-2.

On the other hand, when the post-processing device cannot perform the sealing operation, the procedure proceeds from step b-1 to step b-3, and the recovery procedure is performed even after a certain period of time. If it is confirmed that it is not broken, the process proceeds to step b-4. Then, although the post-processing device creates a wrapping paper, the operation of discharging the recording paper from the paper wrapping device is started without sealing. Therefore, according to the flowchart of FIG. 8, when the labeler cannot continue the normal sealing operation and issues a warning and requests the operator to take action, the recovery process is not performed. It is possible to resume the work of creating the recording paper by ejecting the unwrapped wrapping paper to the discharge tray.

As described above, when the post-processing apparatus of the present invention is used, a plurality of recording paper processing modes are set in the control means of the image forming apparatus and the post-processing apparatus, and the sealing operation is continued. Even if an accident that cannot be done occurs, the device can operate normally. For example, in the post-processing apparatus used by connecting to the image forming apparatus of the present invention, the operation of the following processing can be arbitrarily selected and executed. A Continue recording paper production even if the wrapper cannot be sealed. a: equipped with two discharge trays, a discharge tray for storing recording paper formed as a wrapping paper and a discharge tray for storing unwrapped wrapping paper, in a mode in which the wrapping paper cannot be processed in the sealing mode. The unwrapped wrapping paper is discharged toward the wrapping paper storage and discharge tray. (In this case, the wrapping paper expands.) B: When the wrapping paper cannot be sealed, even if the wrapping paper is designated, the wrapping paper is ejected to the ejection tray for accommodating the unwrapped recording paper. c: Even if it is not possible to seal the sheet, the operator is informed of the state by displaying the state on the display unit while continuing the work of creating the recording sheet.

If the B seal is not possible, the recording paper making operation is stopped. d: The state where the label disappears is detected at an early stage and is output to the display unit. (Many problems will occur if the image forming apparatus performs stop processing during recording sheet formation.) E: When a state in which sealing is impossible occurs, the operation of the apparatus is stopped and the operator is notified. f: When a state that cannot be sealed occurs, the operation of the device is automatically stopped, but if a recovery treatment is performed thereafter,
Allows you to resume the operation that was interrupted.

C. It is possible to set a mode in which the apparatus is stopped depending on the state in which sealing is not possible and a mode in which the recording paper discharging operation is continued even if sealing is not possible, and the two modes can be arbitrarily switched. To g: The operator should switch the mode. h: When a state that cannot be sealed occurs, the operation of the device is temporarily interrupted and displayed on the display unit to inform the operator,
If the recovery process is not performed after the elapse of a certain period of time, the operation for discharging the unsealed wrapping paper is automatically switched. i: When a state that cannot be sealed occurs, the operation of the device is temporarily suspended and displayed on the display unit or the like to inform the operator,
After that, when a recording paper creation command is input a certain number of times or more, the recording paper discharge is restarted in a mode in which no wrapping paper is created. j: The switching of the work mode in the post-processing device is performed by the higher-level device. (For example, when communication with a computer or the like as a host device is established) k: The work mode of the post-processing device can be switched from a remote place using a telephone line. (When the unsealable state occurs, the operation of the device is stopped and the operator is informed by using the telephone line. Then, when the operator performs the recovery process or commands the mode change, As described above, in the control device of the present invention, the control mode is arbitrarily set even in the case where the label runs out and the sealing work for the wrapping paper cannot be continued. As a result, it is possible to avoid interrupting the recording paper making operation in the image forming apparatus. And, for example, when performing unattended operation at night, even if the recording paper is ejected in a non-sealed state, the work can be continued, and the work efficiency such as manually creating the wrapping paper later is sacrificed. However, it is possible to improve the efficiency of creating the recording paper.

[0036]

As described above, according to the present invention, when a paper winding device is connected to the image forming apparatus and a mechanism for discharging the paper in a sealed state is constructed, the paper winding device is used for sealing. Even when there is a shortage of labels or the like to be used, it is possible to continue the work of winding the recording paper and discharge it to the discharge tray if there is no operator nearby. Also,
For example, when the wrapping paper is discharged to the discharge tray without being sealed, the wound recording paper returns to the unwound state, but it is relatively easy to wind the recording paper later. However, it does not significantly hinder work efficiency. Then, when a large amount of large-sized recording paper is created during unattended operation at night, a large amount of recording paper can be created without interrupting the operation of the apparatus. Furthermore, in the case of setting a control mode for the control device of the image forming device or the paper winding device, in which the operation of the device can be stopped or can be selected in a state where the sealing work cannot be continued, It is possible to easily deal with the condition where the operator is nearby and the condition of unmanned operation, and it is possible to improve the movement efficiency of the device.
