Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a continuous form processing device that cuts and divides continuous forms that are continuously printed out and discharged by a printer into a predetermined number of units of forms. It is related to.

[Prior Art] Conventionally, a printer, which is an output device of an electronic computing device, continuously prints out variable information on a continuous form while continuously folding the continuous form at its output section, and then folds the continuous form downward. Previously, the forms were cut using a processing device separate from the printer, but when printing out a large number of continuous forms or when dividing into a predetermined number of forms,
Since folding and reprocessing continuous forms required time and effort and was inconvenient, attempts were made to connect a continuous form processing device dedicated to the printer to the output section of the printer and process the continuous forms at once.

However, conventional continuous form processing devices are designed specifically for that printer, so if you want to remove them and connect them to another printer, you cannot easily remove them. Not only is it difficult to match the speeds, but even when using a dedicated printer, the printing speed is limited by the continuous form processing method and the processing speed at that time, making it inconvenient that the printer's original performance cannot be demonstrated. It was hot.

[Problems to be Solved by the Invention] Therefore, in view of the conventional drawbacks, the present invention solves the following problems even when used exclusively for a printer:
In addition, even when used for general purposes, it can be used without reducing the printer's original performance and can be connected to any printer, and the processing operations of the post-processing device itself can be processed without being affected by the print speed of the printer. A continuous foam processing apparatus is provided.

[Means for Solving the Problems] A continuous form processing apparatus according to the present invention includes a conveyance buffer section that can receive and store continuous forms, and a conveyance buffer section that is located downstream of the conveyance buffer section and that sequentially conveys the continuous forms in the conveyance buffer section. a cutting means for cutting the continuous form into a predetermined number of unit forms while transporting the continuous form on the transport path of the transport means; and a sorting means for dividing the cut unit forms into predetermined unit forms after the transport means. and a sensing means for sensing a division mark attached to a desired unit form in advance on the conveying path of the conveying means during sorting, and the conveying speed of the conveying means is adjusted when the amount of continuous forms in the conveying buffer section is less than a predetermined value. The speed is controlled so that it is slow, and becomes faster when it is more than a predetermined value, and the sorting means is driven by an output signal outputted based on the detection of the sorting mark attached to the unit form being conveyed by the sensing means. A control means is provided for controlling the conveyance speed to a level that does not interfere with driving the sorting means, giving priority to the control based on the amount of continuous foam in the conveyance buffer section.

[Function] Therefore, the continuous form processing device absorbs changes in the print speed of the printer by the conveyance buffer, and controls the processing speed of the processing device by the continuous form stock amount of the conveyance buffer. Since the conveyance speed reduction required for the processing of the sorting means of the apparatus is carried out with priority over the above-mentioned control, the sorting work of the processing apparatus and the printing speed of the printer can be performed without any restrictions.

[Examples] Next, the present invention will be explained based on drawings showing examples thereof.

It may also be configured such that a signal issued upon completion of driving brings the device into a reset state, and the electromagnetic clutch connects with the drive motor 31 so that conveyance, cutting, and sorting can be performed again.

Further, in the sorting means 50, a drive mechanism having a chain structure that rotates left and right alternately to drive the stacking table 54, or a sorting means that separates the stacking table 54 without moving it may be used.

[Effects] The continuous form processing device of the present invention as described above can be used regardless of whether the speed of the printer, which is the output device of the electronic computing device, is high or low, and even if the speed of the same printer varies. Even in the case where a division mark is provided for each small unit form and frequent division is required, there is no impact on printout speed due to the control of the transport means using the transport buffer that allows storage and the division mark sensing means. It can be divided into a predetermined number of unit forms without having to print them out, and is very useful as an apparatus that processes continuous forms at the same time as printing out.
