Description

용지 걸림 판단 방법How to determine the jam

본 발명은 용지걸림 판단 방법에 관한 것으로, 특히 용지걸림에 의한 라인피드모터의 과부하 유무를 감지하여 과부하시 라인피드모터를 역회전시켜 용지를 자동으로 제거하는 용지걸림 판단 방법에 관한 것이다.The present invention relates to a paper jam determination method, and more particularly, to a paper jam determination method for automatically detecting a paper feed by detecting the presence of an overload of the line feed motor due to a paper jam and rotating the line feed motor in reverse.

팩시밀리 또는 스캐너와 프린터로 구성된 복합기에 있어서, 화상데이타가 기록된 원고의 화상데이타를 독취하거나 기록지에 하상데이타를 인쇄하기 위하여 스텝 모터(Step Motor)로 구성된 라인피드모터를 구동시켜 원고나 기록지인 용지를 피딩(Feeding)시킨다.In a multifunction device composed of a facsimile machine or a scanner and a printer, a paper which is a document or a recording paper by driving a line feed motor composed of a step motor to read image data of an original on which image data is recorded or to print bottom image data on a recording paper. Feed the (Feeding).

종래의 팩시밀리 또는 복합기의 경우 독취명령이나 인쇄명령이 있으면 스텝모터를 구동를 구동시켜 피딩롤러(Feeding Roller)를 회전시키고 이로인해 용지는 피딩되며, 용지 피딩시 광센서와 액튜에이터 피드(Actuator Feed)로 구성된 용지감지센서는 액튜에이터 피드가 광센서로부터 이탈되어 용지의 유무를 감지한다. 독취나 인쇄가 완료되어 용지가 배출되거나 용지가 없을때는 액튜에이터 피드는 광센서를 가로막아 용지감지센서는 용지가 없음을 감지한다.In the case of a conventional facsimile machine or a multifunction machine, when a read command or a print command is issued, a stepping motor is driven to rotate a feeding roller, and the paper is fed by the feeder. The paper sensor detects the presence or absence of paper from the actuator feed from the light sensor. When the reading or printing is completed and the paper is discharged or there is no paper, the actuator feed intercepts the light sensor and the paper sensor detects the absence of paper.

It stops work in progress by judging that a jam that cannot perform an operation has occurred, and informs the user of a jam occurrence alarm or alarm by using a light emitting diode or a liquid crystal display. Can be used to generate a warning sound. By warning or alarm sound of jam occurrence, the user removes jammed paper by manual operation.

따라서 종래의 팩시밀리 또는 복합기는 용지가 걸려 잼이 발생된 경우 일일이 잼발생을 일으킨 용지를 수동으로 제거하여야 하고, 용지가 피딩롤러에 감긴 경우에는 용이하게 용지를 제거하기 힘들며, 심지어는 시스템을 분해하여 용지를 제거하여야 하는 문제점을 가지고 있다.Therefore, a conventional facsimile machine or a multifunction machine has to manually remove the paper that caused the jam if the paper jams, and if the paper is wound on the feeding roller, it is difficult to remove the paper easily.

상기의 구성에 따른 본 발명인 용지걸림 판단 방법의 동작은 다음과 같다.Operation of the paper jam determination method of the present invention according to the above configuration is as follows.

복합기 또는 프린터에서 기록용지에 화상데이타를 인쇄하는 인쇄명령이나 복합기 또는 펙시밀리에서 화상상데이타가 기록된 원고를 독취하는 독취명령이 있으면 모터구동단계(S10)는 라인피드모터를 구동시킨다. 라인피드모터가 구동되면 라인피드모터에 연결된 기어부들이 각각 회전을 한다. 모터구동단계(S10)에서 도2의 라인피드모터 및 기어부(2)가 구동되면 피딩롤러(1)를 회전시켜 용지를 피딩한다. 과부하감지단계(S30)는 도2에서 라인피드모터 및 기어부(2)의 구동에 따라 라인피드모터 및 기어부(2)에 연결된 피딩롤러(1)의 회전축(X1)은 회전하여 용지를 피딩하는 피딩롤러(1)가 회전되고, 피딩롤러(1)의 회전축(X2)에 일단이 연결된 레버(L)는 피딩롤러(1)의 회전에 의해 레버(L)의 타단이 움직이고 레버(L)의 타단이 광센서(LS)를 가로막으면 광센서(LS)는 오프되고 레버(L)의 타단이 광센서(LS)로부터 이탈되면 광센서(LS)는 온되므로 만약에 용지의 걸림이 발생되지 않으면 피딩롤러(1)는 정속도로 회전하여 광센서(LS)의 온, 오프 시간은 일정하고, 용지의 걸림이 발생되면 피딩롤러(1)는 느리게 회전하여 광센서(LS)의 온, 오프 시간은 느려지고 이로인해 라인피드모터에는 과부하가 걸린다. 따라서 과부하감지단계(S30)는 광센서(LS)의 온, 오프시간을 검출하여 용지의 걸림이 발생되지 않을때의 정상의 광센서(LS)의 온, 오프시간과를 비교해서 광센서(LS)의 온, 오프시간이 길어지면 용지가 용지이동 통로의 어디에선가 잼이 발생된 것을 알 수 있고, 이로인해 라인피드모터는 용지가 잼에 걸리지 않을 때, 즉, 용지 피딩시 라인피드모터에 용지피딩에 의해 정상적으로 발생되는 부하가 걸리 때 보다 큰 과부하가 발생된 것을 알 수 있다. 모터역회전단계(S40)는 과부하감지단계(S30)에서 과부하가 발생되면, 즉 광센서(LS)의 온, 오프시간이 정상적으로 피딩롤러가 회전할 때 보다 길어지면 라인피드모터를 역회전시켜 용지를 용지피딩 방향과 반대방향으로 배출한다.If there is a print command for printing image data on a recording sheet in a multifunction printer or a printer or a read command for reading a document on which image data is recorded in a multifunction printer or fax machine, the motor driving step (S10) drives the line feed motor. When the line feed motor is driven, the gear parts connected to the line feed motor rotate. When the line feed motor and the gear unit 2 of FIG. 2 are driven in the motor driving step S10, the feeding roller 1 is rotated to feed the paper. In the overload detection step S30, the rotary shaft X1 of the feeding roller 1 connected to the line feed motor and the gear unit 2 rotates as the line feed motor and the gear unit 2 are driven in FIG. 2 to feed the paper. The feeding roller 1 is rotated, and the lever L having one end connected to the rotating shaft X2 of the feeding roller 1 moves the other end of the lever L by the rotation of the feeding roller 1 and the lever L. If the other end of the light sensor (LS) intercepts the light sensor (LS) is off, if the other end of the lever (L) is separated from the light sensor (LS), the light sensor (LS) is on, so if the paper jam occurs Otherwise, the feeding roller 1 rotates at a constant speed so that the on / off time of the light sensor LS is constant, and when a paper jam occurs, the feeding roller 1 rotates slowly to turn on and off the light sensor LS. Will slow down and overload the line feed motor. Therefore, the overload detection step S30 detects the on / off time of the light sensor LS and compares the on / off time of the normal light sensor LS when no paper jam occurs. When the on / off time of) increases, it can be seen that the paper is jammed somewhere in the paper moving path, which causes the line feed motor to feed the paper to the line feed motor when the paper does not jam. It can be seen that a greater overload occurs when the load normally generated by feeding is applied. When the overload is detected in the overload detection step S30, that is, when the on / off time of the optical sensor LS is longer than when the feeding roller is normally rotated, the motor reverse rotation step S40 reverses the line feed motor to rotate the paper. Discharge in the direction opposite to the paper feeding direction.

따라서 본 발명인 용지걸림 판단 방법은 피딩롤러의 회전축(X1)에 연결된 레버(L)와 광센서(LS)에 의하여 광센서(LS)의 온, 오프시간을 검출하여 스텝모터인 라인피드모터에 과부하가 발생되는 지의 유무를 감지하여 과부하가 발생되면 용지는 잼이 발생된 것으로 판단하고 라인피드모터를 역회전시켜 용지를 용지피딩 방향과 반대방향으로 배출시켜 잼이 발생된 용지를 자동으로 제거할 수 있다.Therefore, the paper jam determination method of the present invention detects the on / off time of the optical sensor LS by the lever L and the optical sensor LS connected to the rotating shaft X1 of the feeding roller, thereby overloading the line feed motor as a step motor. Is detected, if the overload occurs, the paper is judged to have jammed and the line feed motor can be rotated backward to discharge the paper in the opposite direction to the paper feeding direction to automatically remove the jammed paper. have.
