Description

Paper processing device

The present invention relates to a sheet processing apparatus, and more particularly to a sheet processing apparatus having a paper tray and a paper pressing device.

Printers, scanners, etc. are common office machines. In order to meet the diverse needs of users and integrate more functions, the transaction machine automatically prints the printer by adding paper processing devices such as staplers and hole punchers. Multi-page files output by the machine or scanner are bound into a book or holed in the same position of a multi-page document to make the user's workflow smoother. The paper handling device has a paper loading platform for placing multiple pages of documents output by the printer or scanner. The paper processing device performs a whole process of arranging a plurality of pages of documents and binding, punching, and the like on the paper loading platform, and then discharging the plurality of pages of documents to a tray located outside the transaction machine for the user to take.

Please refer to FIG. 6, FIG. 7, and FIG. 9 to FIG. 12. FIG. 9 is a schematic view showing the first operation of the driving device, the paper feeding device and the paper pressing device of the paper processing device according to a preferred embodiment of the present invention, FIG. A first perspective view showing a paper processing apparatus according to a preferred embodiment of the present invention when no paper self-feeding paper platform is pushed to the paper tray, and FIG. 11 is a view showing a paper processing apparatus according to a preferred embodiment of the present invention. A second perspective view of any of the paper processing devices of the preferred embodiment of the present invention is shown in FIG. 12, which is a second perspective view of the paper processing apparatus of the preferred embodiment of the present invention.

First, as shown in FIG. 6 and FIG. 7, when the paper processing device 2 has not been activated, the bracket 222d of the paper feeding device 22 stays close to one of the first pulleys 222a together with the paper tray 221, at which time the bracket 222d triggers the first Two sensing devices 222e.

At the same time, the first casing 231a of the platen arm 231 of the platen device 23 stays in a direction away from the paper tray 221, so that the pressing portion 231b does not protrude above the paper tray 2.

The second ejection portion 243d of the paper discharge device 24 stays under the first rotating shaft 241.

Referring to FIG. 7 and FIG. 9 to FIG. 11 , when the paper processing device 2 is activated, the motor 211 of the driving device 21 drives the first gear 212 and the second transmission shaft 215 to rotate in the second direction Y, so that the second gear 213 drives the second gear 213. The first drive shaft 214 rotates in a first direction X.

Then, the first pulley 222a of the first transmission device 222 rotates along the first transmission shaft 214 in the first direction X, thereby driving the belt 222c and the bracket 222d to move the paper tray 221 upward.

At the same time, the torque limiter 232b of the second transmission 232 is driven by the second transmission shaft 215. The interlocking device 232c rotates together with the sleeve 232a in the first direction X.

The first housing 231a of the platen arm 231 rotates together with the sleeve 232a in the first direction X, and the pressing portion 231b is returned to the lower side of the paper loading platform 25.

Referring to FIG. 7, the platen arm 231, the sleeve 232a, the linkage 232c, and the torque limiter 232b will rotate in the first direction X until the angle limiting device 232cb is blocked by the second transmission shaft 215.

When the paper tray 221 is moved downward by a predetermined distance, the driving device 21 stops driving the paper feeding device 22 and the paper pressing device 23, as shown in FIG. 16, at this time, the paper tray 221 carries a plurality of sheets S, and the paper pressing arm 231 It is located below the paper loading platform 25.

Finally, please refer to FIG. 4, FIG. 12, FIG. 17, and FIG. 18. FIG. 17 is a perspective view showing a paper processing apparatus according to a preferred embodiment of the present invention when a plurality of paper contact pressing portions on the paper tray are contacted, FIG. A perspective view showing a paper processing apparatus according to a preferred embodiment of the present invention after a plurality of sheets of paper pushing pressing portions on a paper tray are rotated.

When the second ejection portion 243d of the paper discharge device 24 bypasses the second rotating shaft 242 and moves under the paper loading platform 25, the driving device 21 drives the paper feeding device 22 and the paper pressing device 23 again, so that the paper tray 221 is moved upward and pressed. The paper arm 231 is rotated toward the paper tray 221 to press against the plurality of sheets S.

In detail, referring to FIG. 9 at the same time, first, the motor 211 drives the first gear 212 and the second transmission shaft 215 to rotate in the second direction Y, so that the second gear 213 drives the first transmission shaft 214 to rotate in the first direction X.

Then, the first pulley 222a of the first transmission device 222 rotates along the first transmission shaft 214 in the first direction X, thereby driving the belt 222c and the bracket 222d to move the paper tray 221 upward.

When the bracket 222d moves, the first auxiliary roller 222fa and the second auxiliary roller 222fb rotate and move up and down along the first guide 222fc and the second guide 222fd to reduce the resistance when the bracket 222d moves.

At the same time, the torque limiter 232b of the second transmission device 232 also rotates along the second transmission shaft 215 in the second direction Y, thereby driving the linkage device 232c to rotate together with the sleeve 232a in the second direction Y.

The first housing 231a of the platen arm 231 rotates together with the sleeve 232a in the second direction Y, so that the pressing portion 231b protrudes above the paper tray 221, as described above, the paper pressing arm 231, the sleeve 232a, The interlocking device 232c and the torque limiter 232b will rotate until the angle limiting device 232cb is blocked by the second transmission shaft 215, and the paper tray 221 will be driven by the first transmission shaft 214 to continuously move upward, so that the plurality of sheets S contact the pressing portion. 231b, as shown in FIG.

Then, the paper tray 221 continues to move upward, so that the pressing portion 231b flattens the plurality of sheets S, and the pressing portion 231b is pushed and rotated by the plurality of sheets S, and when the pressing portion 231b is rotated to the lower portion of the pressing portion 231b When a sensing device 231c is triggered, as shown in FIG. 12, the driving device 21 will stop driving the paper feeding device 22 and the platen device 23, so that the paper feeding device 22 and the platen device 23 stay at the position shown in FIG. And waiting to accept multiple papers again.

It can be seen from the above preferred embodiment that the driving device 21 simultaneously drives the first transmission device 222 and the second transmission device 232 to raise the paper tray 221 while the paper pressing arm 231 rotates toward the paper tray 221 . The pressing portion 231b is moved over the paper tray 221 to flatten the plurality of sheets S on the paper tray 221 .

In summary, the present invention rotates the paper pressing arm 231 together with the second transmission shaft 215 by the torque limiter 232b (Torque Limiter), the sleeve 232a, and the linking device 232c.
