Description

可調節驅動力的取紙模組及其調節驅動力之方法Paper taking module capable of adjusting driving force and method for adjusting driving force

本發明涉及一種取紙模組，特別指一種自動調整取紙驅動力的取紙模組及其調節驅動力之方法。The invention relates to a paper taking module, in particular to a paper taking module which automatically adjusts the driving force of the paper taking and a method for adjusting the driving force.

請參閱第四圖，為了從進紙匣中逐次取出單一紙張並饋送通過饋紙通道，一般的取紙模組中包含設置於進紙匣處的取紙輪30’，以及設置於取紙輪30’下游的分張輪組40’。其中的取紙輪30’對待饋送紙張施加一驅動力，該驅動力大於待饋送紙張與其餘紙張的摩擦力，因而使所述待饋送紙張與其餘紙張分開並向所述饋紙通道的下游方向前進。Please refer to the fourth figure. In order to take out a single sheet of paper from the paper tray and feed it through the paper feeding channel, a general paper picking module includes a paper picking wheel 30' arranged at the paper feeding tray and a paper picking wheel. The 30' downstream splitter wheel group 40'. The pickup wheel 30' exerts a driving force on the paper to be fed, which is greater than the friction between the paper to be fed and the rest of the paper, so that the paper to be fed is separated from the rest of the paper and moves toward the downstream direction of the paper feeding channel. go ahead.

但若是所述取紙輪30’無法保證一次只取送一張待饋送紙張，因此在所述取紙輪30’的下游設置分張輪組40’，所述分張輪組40’包含一驅動輪41’以及一阻力輪42’，其中所述驅動輪41’對紙張施予的驅動力大於所述阻力輪42’對紙張施加的阻力，因此正常饋送的紙張在所述驅動輪41’的驅動下被饋送通過所述分張輪組40’，而重複饋送的紙張則會被所述阻力輪42’所阻擋。透過所述分張輪組40’的設計使重複饋送的紙張被阻擋下來，並讓正常饋送的紙張通過，進而確保每次都能從進紙匣中取出單一紙張並饋送通過饋紙通道。However, if the paper pick-up wheel 30' cannot guarantee that only one sheet to be fed will be fed at a time, a sheet-separating wheel group 40' is provided downstream of the paper pick-up wheel 30'. A driving wheel 41' and a resistance wheel 42', wherein the driving force exerted by the driving wheel 41' on the paper is greater than the resistance exerted by the resistance wheel 42' on the paper, so the normally fed paper is on the driving wheel 41' The paper is fed through the splitting wheel group 40' under the driving of, and the paper that is repeatedly fed will be blocked by the resistance wheel 42'. Through the design of the separation wheel 40', the repeatedly fed paper is blocked, and the normally fed paper is passed through, thereby ensuring that a single paper can be taken out of the paper tray and fed through the paper feeding channel every time.

由此可知，取紙模組需要讓驅動力與阻力完美配合才能確保饋紙過程的正確無誤，當所述驅動力過大或過小時都會發生饋紙錯誤。然而由於紙張的種類或厚度不同，實務上難以以一通用的設定值來取送各種不同的紙張。若所述取紙輪30’設定的驅動力過小，則所述待饋送紙張將無法順利被饋送而停留在進紙匣中。相反的若是驅動力設定過大，則在饋送紙張通過所述分張輪組40’時，重複饋送的紙張與待饋送紙張之間將產生過大的摩擦力而使所述重複饋送的紙張一併被強行饋送通過所述分張輪組40’，或者是因所述分張輪組40’的推擠而使較薄的紙張產生皺摺。It can be seen that the paper picking module needs a perfect match between the driving force and the resistance to ensure the correctness of the paper feeding process, and paper feeding errors will occur when the driving force is too large or too small. However, due to the different types or thicknesses of paper, it is difficult in practice to use a common set value to fetch various papers. If the driving force set by the pickup wheel 30' is too small, the paper to be fed cannot be fed smoothly and stays in the paper input tray. On the contrary, if the driving force is set too large, when the fed paper passes through the separation wheel 40', excessive friction will be generated between the repeatedly fed paper and the paper to be fed, so that the repeatedly fed paper will be taken together. Forcibly feeding through the splitting wheel group 40', or creases of the thinner paper due to the pushing of the splitting wheel group 40'.

The process of adjusting the driving force of the paper picking through this creation is as follows: A driving force of a predetermined size is applied to the paper through a picking wheel 30 to feed the paper through a paper separating wheel set. And through the rotation speed of the pickup wheel 30 to estimate and obtain the preset paper feeding speed V0 of the pickup wheel 30, the moving speed of the paper to be fed in the normal feeding state should be equal to the preset paper pickup wheel 30 Set the paper feed speed V0. Then the driving force measuring unit 50 is used to confirm whether the paper is normally fed, and the driving force measuring unit measures the moving speed V1 of the paper before passing through the paper separating wheel through the first speed measuring wheel 51 and The second speed measuring wheel 52 is used to measure the speed V2 after passing through the paper separating wheel tissue. When the speed V0 is greater than the speed V1, it means that the driving force of the paper is insufficient at this time, so the paper does not move at the preset speed V0 of the paper take-up wheel 30. In order to ensure that the paper is correctly fed, the solenoid valve 22 is controlled to increase the output. At this time, the paper pick-up swing arm 21 will approach the paper under the action of the solenoid valve 22, thereby increasing the pick-up wheel 30 to the paper. The positive force and driving force. On the contrary, when the speed V1 is greater than the speed V2, it means that the paper is subjected to excessive driving force at this time. In order to prevent the paper from being pushed and wrinkled, the solenoid valve 22 is controlled to reduce the output. At this time, the paper pickup swing arm 21 will move away from the paper under the action of the return spring 23, thereby reducing the positive force and driving force of the paper pickup wheel 30 on the paper.
