Aligning apparatus and enclosing and sealing apparatus

Abstract

When the width of an envelope has sufficient margin for the width of a paper sheet, the aligning operation is skipped to improve productivity. As shown in FIG. 2, in an aligning apparatus 1 including an aligning unit 4 that aligns both side edges of the conveyed paper sheets, a difference value and a predetermined threshold value for use in an aligning operation execution determination are compared. The difference value is calculated by subtracting width dimension obtained from sheet size information of the paper sheet to be aligned from width dimension obtained from envelope size information of the envelope to enclose the paper sheet. The controller 7 controls not to execute the aligning operation if the difference value exceeds the predetermined threshold value.

1 . An aligning apparatus including an aligning unit that aligns both side edges of conveyed paper sheets, the aligning apparatus comprising a controller,
 wherein the controller compares a difference value with a predetermined threshold value for use in an aligning operation execution determination, and controls not to execute an aligning operation if the difference value exceeds the threshold value, the difference value being calculated by subtracting sheet size information of the paper sheet from envelope size information of an envelope to enclose the paper sheet to be aligned.   
     
     
         2 . The aligning apparatus according to  claim 1 ,
 wherein the aligning apparatus is disposed at a preceding stage of enclosing and sealing unit which encloses and seals the paper sheet in the envelope, and   the controller controls the enclosing and sealing unit not to execute a position adjustment of the envelope and the paper sheets to match one another when the controller determines that the aligning operation of the paper sheet is not executed.   
     
     
         3 . The aligning apparatus according to  claim 1 ,
 wherein the aligning unit includes a pair of aligning plates to align the paper sheets, and   the controller executes control of the aligning plates to move to a sheet receiving position that has a same size as an opening of the envelope based on the envelope size information when the controller determines that the aligning operation of the paper sheet is not executed.   
     
     
         4 . An enclosing and sealing apparatus for conveying an envelope and content, and enclosing and sealing the content in the envelope, the enclosing and sealing apparatus comprising:
 a memory that stores aligning position data based on edge data of a preliminary conveyed plurality of envelopes;   the aligning unit according to  claim 1  that aligns the content and executes a position adjustment;   a controller that controls the aligning unit to adjust the position of the content to the envelope based on the aligning position data of the envelope stored in the memory.   
     
     
         5 . The enclosing and sealing apparatus according to  claim 4 ,
 wherein the edge data includes an amount of deviation and a variation of a position of side edge portions of the envelope in a widthwise direction perpendicular to a conveying direction,   the controller compares a size difference of the envelope to be used and the content in the widthwise direction with the amount of deviation and variation of the edge data,   the controller controls the aligning unit to adjust a position of the content in the widthwise direction by the amount of deviation if the amount of deviation exceeds the size difference and the variation is smaller than the size difference, and   the controller does not control the aligning unit if the amount of deviation and the variation are smaller than the size difference.   
     
     
         6 . The enclosing and sealing apparatus according to  claim 4 , further comprising a sensor that detects a side edge portion of the envelope in the widthwise direction perpendicular to the conveying direction to detect edge data,
 wherein the enclosing and sealing apparatus preliminary conveys a plurality of envelopes and obtains the position of the side edge portions of the envelopes with the sensor, thereby generating the aligning position data, and storing the aligning position data in the memory.   
     
     
         7 . The enclosing and sealing apparatus according to  claim 6 ,
 wherein the aligning position data stored in the memory is reset in association with a change of an enclosed envelope making condition in the enclosing and sealing apparatus, and   the aligning position data is newly obtained in association with an operation of the enclosing and sealing apparatus based on a new enclosed envelope making condition, and stored in the memory.
