Patent Application
20070213189
The present invention relates to a paper folding apparatus and particularly to a paper folding apparatus that can regulate paper folding speed and count the number of paper articles.
The conventional paper folding apparatus mainly aim to perform bending, rolling and folding operations for paper articles such as envelopes, cards and bills in a fixed manner for binding. Reference can be found in prior art. One of them is R.O.C patent publication No. 528008 entitled “Automatic paper folding and pressing apparatus”. It has rollers to automatically direct, fold and press different types of paper to complete paper folding and pressing operations rapidly so that the paper can be fed in a neat fashion and discharged in a bent and folded manner.
Another R.O.C. patent publication No. 537192 entitled “Paper conveying structure for paper folding and sealing machines” includes a paper folding and sealing host with a paper conveying structure on one side. The paper conveying structure includes a chassis, a transmission mechanism, a clutch, and pawls. The clutch has two ends which can be engaged or disengaged to control paper conveying conditions of the pawls. There is a paper folding structure on an outer side of the paper conveying structure which has another set of chassis, transmission mechanism, clutch, pawls and a fender, a detent plate, forming rollers, and heating rollers to fold a lager size paper in half before directing into the paper conveying structure and host. It is suitable to stack paper and fold larger size paper.
However the conventional techniques set forth above cannot classify paper of different thickness. Papers that are too thick or too thin frequently jam in the paper folding apparatus and result in interruption of operation. Moreover, the conventional paper folding apparatus often have to process a great amount of paper articles. Quality control of counting the number of the paper articles is important. To do counting manually is error-prone.
The primary object of the present invention is to solve the aforesaid disadvantages. The present invention provides a paper folding apparatus that can regulate paper folding speed and count paper articles. It includes a casing for holding a paper tray and a paper folding portion. The casing also has at least one paper folding plate on the paper folding portion, and two sides coupling with a paper feeding portion and a paper discharge portion. There is a bracket beneath the casing. The casing has a switch to control switching of a power supply and an operation control portion which contains a circuit board. The circuit board receives signals from an inspection unit of the paper discharge portion. The inspection unit is a sensor to detect the number of paper articles and output a signal to be displayed on a display unit. The paper feeding portion has a paper dispensing unit to do mechanical regulation according to the thickness of paper articles, and a reset control unit to send a signal to the circuit board and send a reset signal to be displayed on the display unit. The operation control portion has a regulation means to regulate paper folding speed. The regulation means can send a regulation signal to the circuit board which outputs a control signal to regulate the speed of the paper folding portion.
The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.
