Description

MULTI-SHEET BUFFER SYSTEM IN SHEET FINISHER
TECHNICAL FIELD
The present invention relates to a sheet finisher of an image forming apparatus such as a printer and a copier, and more particularly to a multi-sheet buffer system that can finish sheets without any delay in the step of moving sheets to a compiler.
BACKGROUND ART
A related art image forming apparatus will be described with reference to FIG. 1.
The image forming apparatus includes a sheet finisher 2. The sheet finisher 2 finishes sheets ejected from the image forming apparatus.
The sheet finisher is structured to perform various finishing steps such as punching, binding, and stapling.
The sheet finisher provided with a stapler 3 will now be described. The related art sheet finisher includes a stapler 3, a compiler 6 that puts sheets in a standby state before the sheets are stapled by the stapler 3, a jogger 7 aligning the sheets stacked on the compiler 6 at the exact working position, a paper moving path 5 moving the sheets to the compiler 6, and a stacker 4 stacking the stapled sheets thereon.
A method of moving the sheets according to the related art sheet finisher will be described with reference to FIGs. 2a and 2b. The sheets are stacked on the complier 6 one by one through a sheet moving path 5. The sheet moving path 5 is provided with an inlet roller 8 and an outlet roller 18. Once a set number of sheets 10 (sheets required for stapling) are stacked on the compiler 6, the sheet moving path 5 stops movement of the sheets while the jogger 7 works to align the sheets stacked on the compiler 6. Once alignment of the sheets 10 is completed, the stapler 3 staples the sheets. Then, the sheet moving path 5 starts to move the sheets until a predetermined number of sheets are stacked on the compiler 6. Such steps are repeated.
The aforementioned related art sheet finisher stops movement of the sheets 11 on the sheet moving path 5 and maintains the standby state while the sheets stacked on the compiler 6 are aligned, stapled and ejected to the stacker 4 (time period corresponding to a portion marked with A in FIG. 2b) .
However, the related art sheet finisher has several problems.
Since movement of the sheets is stopped while they are aligned and stapled, working efficiency is reduced as much as the stopped time and processing speed of the sheets is delayed. Particularly, if a small number of sheets are set and finished, the sheet standby cycle of the sheet moving path becomes frequent. In this case, the whole standby time becomes longer and thus the processing speed of the sheet finisher is remarkably reduced.
DETAILED DESCRIPTION OF THE INVENTION
Technical Problem
The present invention is directed to a multi-sheet buffer system in a sheet finisher that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.
According to a multi-sheet buffer system, a sheet buffer that buffers and stores sheets is provided in a sheet moving path, and a predetermined number of sheets are buffered by the sheet buffer and then the buffered sheets are fed to a compiler.
The sheet buffer of the present invention includes a buffer tray provided between an inlet roller and an outlet roller in a sheet moving path, and a pressurizing roller provided on the buffer tray to be linked with and detached from an idle roller under the control of a signal of a sensor that counts the stacked sheets. The pressurizing roller is linked to the idle roller when a predetermined number of sheets are set and stacked on the buffer tray, so that the sheets stacked on the buffer tray can be moved to the outlet roller at once.
If no sheets to be buffered are required on the buffer tray, i.e., the sheets on the sheet moving path are ejected to the stacker without the finishing step, the pressurizing roller is maintained in a state that it is linked to the idle roller.
Accordingly, an object of the present invention is to provide a multi-sheet buffer system in a sheet finisher in which sheets are moved through an inlet roller without any delay and are not put in a standby mode to improve their finishing efficiency.
Another object of the present invention is to provide a multi-sheet buffer system in a sheet finisher in which sheets can be fed through a sheet moving path at the uniform speed regardless of aligning and finishing steps of the sheet finisher.
Technical Solution
To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described, in a multi-sheet buffer system in a sheet finisher including a sheet moving path, a compiler stacking sheets moving through the sheet moving path, a jogger aligning the sheets stacked on the compiler, and a finishing mechanism finishing the sheets aligned by the jogger, the multi-sheet buffer system comprises a sheet buffer provided between the sheet moving path and the compiler to buffer and stack at least one sheet and move the stacked sheet to the compiler.
The sheet buffer includes an inlet roller and an outlet roller provided on the sheet moving path, a buffer tray provided between the inlet roller and the outlet roller to stack sheets, and a sheet ejection mechanism ejecting the sheets stacked on the buffer tray to the outlet roller at once. The sheet ejection mechanism includes an idle roller protruded on the buffer tray, and a pressurizing roller provided apart from the buffer tray to be linked with and detached from the idle roller, the sheets stacked on the buffer tray being positioned between the idle roller and the pressurizing roller.
A guide is provided between the buffer tray and the inlet roller to guide sheets to be stacked at the exact position on the buffer tray.
Advantageous Effects
In the multi-sheet buffer system of the present invention, the buffer tray is provided between the inlet roller and the outlet roller in the sheet moving path, and the pressurizing roller is provided on the buffer tray to be linked with and detached from the idle roller. The pressurizing roller is linked to the idle roller when a predetermined number of sheets are set and stacked on the buffer tray, so that the sheets stacked on the buffer tray can be moved to the outlet roller at once. In this structure, the sheets are moved through the inlet roller without any delay and then are not put in the standby mode, Thus, finishing efficiency of the sheets can be improved. Further, the sheets can be fed through the sheet moving path at the uniform speed regardless of the aligning and finishing steps of the sheet finisher.

Best Mode
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
A multi-sheet buffer system in a sheet finisher according to the present invention will be described with reference to FIGS. 4 to 7.
A multi-sheet buffer system 102 in a sheet finisher of the present invention includes a sheet moving path 105 between an inlet roller 108 and an outlet roller 118, a buffer tray 126 provided in the sheet moving path 105 to stack sheets moving from the path and temporarily keeping the sheets, and a sheet buffer 125 constituting a sheet ejection mechanism 120 ejecting the sheets on the buffer tray to a complier 106.
The sheet ejection mechanism 120 includes an idle roller 128 protruded on the buffer tray 126, and a pressurizing roller 130 provided apart from the buffer tray to be linked with and detached from the idle roller 128. The pressurizing roller 130 is controlled by a sheet sensor 133 provided in the vicinity of the inlet roller 108. The buffer tray 126 is provided with a guide 134 that pushes sheets 111 toward the buffer tray to stack the sheets at the exact position on the buffer tray. The buffer tray 126 has a size greater than that of the sheets so that the sheets are not moved to the outlet roller 118 until the pressurizing roller 130 works.
The sheet stacked on the buffer tray is fed to the compiler 106 as the pressurizing roller works. Once a predetermined number of sheets 110 are fed to the compiler 106, a jogger 107 works to align the sheets. The jogger 107 moves the sheets to a stapler 103 that serves as a sheet finisher. While the stapler 103 has been illustrated as the sheet finisher in the present invention, a punch or a book type binder made with a tape may be used as the sheet finisher.
A method of finishing sheets according to the multi- sheet buffer system in the sheet finisher of the present invention will be described with reference to FIG. 8 and FIGS. 4 to 7.
First, the multi-sheet buffer system in the sheet finisher is initiated in step SlOl and finishing sheets 111 are fed to the inlet roller 108 in step S102. Then, the number of sheets to be stacked on the buffer tray is set by a control system (not shown) of the sheet finisher in step S103. Once the number of sheets is set as above, the sheets 111 are moved along the sheet moving path through the inlet roller 108. The sheets that had passed through the inlet roller 108 are moved to the butter tray 126. The sheets are stacked on the buffer tray 126 as much as the set number of sheets by the operation of the sensor 133 in steps S104 and S105.
Once jam or sheet moving error occurs in the sheet moving path in the step of operating the sensor, the sheet finisher is put in a standby state until a user releases such jam or error.
Meanwhile, the pressurizing roller 130 is maintained detached from the idle roller 128 as shown in FIG. 4 until the set number of sheets is stacked on the buffer tray 126, Once the set number of sheets is completely stacked, the pressurizing roller works as shown in FIG. 5 in step S106 and is linked to the idle roller 128 so as to move the sheets 111 buffered on the buffer tray 126 to the outlet roller 118 in step S107. The sheets moved to the outlet roller are stacked on the compiler 106. Once a predetermined number of finishing sheets 110 are stacked on the compiler, the jogger 107 works to align the sheets stacked on the compiler 106. The sheets aligned on the compiler are finished by the stapler 103 and then ejected to a stacker 104.
As described above, the multi-sheet buffer system is structured in such a manner that the sheets moving through the inlet roller 108 are stacked on the buffer tray 126 while another sheets stacked on the compiler 106 are finished (the jogger works to align the sheets and ejects them to the stacker 104 after stapling) . As a result, the sheets buffered on the buffer tray are moved to the compiler 106 when the finishing step on the compiler ends. Therefore, the sheets moving through the inlet roller 108 are fed to the buffer tray at a certain time period without any standby time. This does not lead to loss of the working time that may occur in the step of finishing sheets. Efficiency of the sheet finisher can also be improved. Working timing of the pressurizing roller, i.e., setting of the number of buffering sheets is properly controlled depending on the sheet finishing time of the compiler. In a state that the stapler is not driven, (i.e., the sheets are not finished on the compiler 106) , one buffering sheet is set and the pressurizing roller 130 is linked to the idle roller 128 to directly eject the sheet 111 moving through the sheet moving path to the stacker 104 without allowing the sheet 111 to be stacked on the buffer tray 126.
