Abstract

Disclosed are a device and a method for automatically feeding paper into a printer. The automatic paper feeding device of a printer comprises a first paper tray (122), a second paper tray (123), a printer paper feeding mechanism (100), a first passage (121) for leading printer paper (116a) to the printer paper feeding mechanism (100) during printing, a printer paper depletion detector (141, 241), and a spare printer paper conveying mechanism (130, 230). When the printer paper depletion detector (141, 241) detects that the printer paper (116a) is depleted during printing, the spare printer paper conveying mechanism (130, 230) conveys spare printer paper (118a) into the printer paper feeding mechanism (100) for printing, thereby realizing automatic paper feeding. The spare printer paper can be automatically conveyed into the printer paper feeding mechanism after the printer paper is depleted, so as to ensure that the printing working is not interrupted, and a user only needs to add a set of printer paper before the spare printer paper is depleted.

Description

打印机自动续纸的装置和方法 Device and method for automatically reprinting a printer

技术领域 Technical field

[0001] 本发明涉及打印机技术领域，尤其是涉及一种打印机自动续纸的装置和方法。 [0001] The present invention relates to the field of printer technology, and in particular, to an apparatus and method for automatically converting a printer.

背景技术 Background technique

[0002] 使用连续式打印纸的打印机不能够像使用单张式打印纸（如 A4幅面打印纸）打印机那样可以在纸仓中的纸用完之前就补充进来，而必须是当前使用的这一卷或一叠纸用完之后才能更换打印纸。这在实际使用中会造成很多麻烦。比如，商场收银员在忙碌的吋候突然收据机的打印纸卷用完了，必须停下来更换一卷新的打印纸，忙碌中更增加了紧张感。又比如，快递公司营业窗口，在接收客户投递物品吋突然电子面单打印机的打印纸用完了，工作人员必须停下手头的工作，更换一叠新的电子面单。此吋如果有客户排队等候，工作人员难免会手忙脚乱，使客户体验降低。 [0002] Printers using continuous printing paper cannot be replenished before the paper in the paper bin is used, as with a single-sheet printing paper (such as A4 format printing paper), but it must be the one currently used. The paper can be replaced after the roll or a stack of paper has been used up. This can cause a lot of trouble in actual use. For example, when the cashier at the mall suddenly runs out of paper, the receipt paper must be stopped and replaced with a new roll of paper, which adds to the tension. For example, in the business window of the courier company, after receiving the goods delivered by the customer, the printing paper of the electronic printer is suddenly used up, and the staff must stop the work at hand and replace the stack of new electronic sheets. If there are customers waiting in line, the staff will inevitably be in a hurry and reduce the customer experience.

[0003] 申请号为 200710169403.9"向打印机供纸的装置和方法 "的发明专利试图提供一种能够装置两卷以上的供纸装置配备在销售点打印机上，当其中一卷纸用尽吋，可以自动切换到另一卷纸。操作者只需在两卷（或以上）纸都耗尽之前向打印机添纸以防止停机。但是此发明的结构过于复杂，成本也高，纸仓位置设置复杂难操作。该发明要求每一卷纸都要配备各自的进纸机构即辊子组，使得打印机结构复杂，操作和维护都不方便。比如，使用最普遍的热敏型销售点打印机其打印头与胶辊组合就是打印机的进纸机构，无需额外辊子组进纸。另外，各纸卷的纸仓分别设置在固定位置不能互通，不便于提升操作方便性。并且，当出现卡纸等故障吋清除故障会很不方便；尤其是当打印带有背胶的不干胶纸吋，不干胶粘到发明中所必须采用的辊子吋，非常难以清除。 [0003] The invention patent of Application No. 200710169403.9 "Device and Method for Feeding Paper to Printer" attempts to provide a paper feeding device capable of installing two or more rolls on a point-of-sale printer, when one of the rolls of paper is exhausted, Automatically switch to another roll of paper. The operator only needs to add paper to the printer before both rolls (or more) are exhausted to prevent downtime. However, the structure of the invention is too complicated and costly, and the position of the paper bin is complicated to operate. The invention requires that each roll of paper be provided with a respective paper feed mechanism, i.e., a roller set, which complicates the structure of the printer and is inconvenient to operate and maintain. For example, the most common type of thermal point-of-sale printer is the combination of the print head and the rubber roller, which is the paper feed mechanism of the printer, eliminating the need for additional roller sets. In addition, the paper bins of the paper rolls are respectively disposed at fixed positions and cannot be inter-connected, which is not convenient for improving the operation convenience. Moreover, it is inconvenient to clear the trouble when there is a paper jam or the like; especially when printing a self-adhesive paper with a backing, it is very difficult to remove the adhesive which must be used in the invention.

技术问题 technical problem

[0004] 本发明的目的在于提供一种能自动续纸的供纸装置并用于打印连续式打印纸的打印机。 An object of the present invention is to provide a printer capable of automatically feeding a paper feeding device and for printing a continuous printing paper.
