本考案は封書、ハガキ、カード等の紙葉類を自
動的に処理する機械に使用される(以下郵便機械
と呼ぶ)の紙葉類の供給装置に関する。[Detailed Description of the Invention] The present invention relates to a paper sheet feeding device used in a machine (hereinafter referred to as a postal machine) that automatically processes paper sheets such as sealed letters, postcards, and cards.

類の末端と次の紙葉類の先端の間隔、すなわち紙
葉類相互の間隔は、紙葉類の長さが一定でないた
め、一定ではない。 As shown in Fig. 1, a conventional feeding device runs a group of paper sheets 1 stored with their ends aligned at a uniform speed in front of a main vacuum chamber 2, and is capable of mechanical processing. A suction belt 3, which has suction holes equally spaced at intervals equal to the length of the longest sheet and the necessary clearance for mechanical processing, picks up the sheets one by one and sends them out onto the conveyance path. . In this case, the distances between the front and rear paper sheets sent out from one end to the next end are equal intervals, so this delivery method is called "end feeding". In this end feed, even if the distance between the ends is constant, the distance between the end of the previous sheet and the leading edge of the next sheet, that is, the distance between the sheets, is not constant depending on the length of the sheet. Therefore, it is not constant.

記一定値より長くなり、その分機械には処理能力
上余裕ができることになる。 When paper sheets are conveyed at a constant speed and processed continuously, the distance between sheets is an important factor that limits the maximum processing speed of a mail machine, and the machine will not operate normally if the distance falls below a certain value. There are no. In the case of end feed, the end spacing is determined according to the longest paper sheet to be processed so that the spacing does not fall below a certain value.In the case of short paper sheets, the spacing will be longer than the above fixed value. , the machine will have more processing capacity.

保つて送り出すことはできなかつた。 In order to make full use of the machine's capacity and maximize machine processing speed, the above-mentioned distance from the feeding device should always be kept at the minimum interval for machine processing, regardless of the length of the paper sheets. I need to send it out. In the conventional end-feeding method, as described above, when sheets of different lengths are used, it is not possible to feed the sheets while maintaining a constant interval between the sheets.

いる。 The present invention will be described in detail below with reference to the drawings showing an embodiment of the present invention. FIG. 2 is a diagram showing an embodiment of the present invention, and FIG. 3 is a diagram showing a control block diagram. Suction holes are formed in the suction belt 4 at regular intervals equal to the length of the longest sheet to be processed plus the clearance required for mechanical processing, and these suction holes connect the main vacuum suction chamber 5. When passing, a suction force is generated, and from among the group of paper sheets 6 stored with their ends aligned, the one closest to the main vacuum suction chamber is taken out and transferred to the conveyance path 7. Sent out. At this time, an auxiliary vacuum suction chamber 8 is provided at the end of the stored paper sheets to prevent the next sheet from being pulled out due to friction or the like.
In addition, the end portion of the paper sheet to be sent out next to the conveyance path is attracted and prevented from being dragged and sent out.

(アイドルローラ)が設けられている。 The suction belt 4 is driven by a drive roller 9, and the drive roller is attached to the shaft of a control motor 10 whose rotation speed can be changed, for example, between normal rotation and high speed rotation. Like the drive roller 9, the gap correction roller 11 is also attached to the shaft of a control motor 12 whose rotation speed is variable, for example, capable of switching between normal rotation and high-speed rotation. Further, a roller 13 faces and contacts this gap correction roller and rotates following the roller 11.
(idle roller) is provided.

力がモータ制御回路16及び17に送られる。 To explain the operation, the distance between sheets that have been attracted by the suction belt and sent out to the conveyance path 7 is measured by the control signal generation circuit 15 based on a signal from the detector 14 (for example, a photoelectric converter). In other words, the minimum distance between sheets that is permissible for mechanical processing,
A signal proportional to the difference from the actually measured interval (for example, the number of pulses or the width of the pulse, or the magnitude of the voltage) is generated by the control signal generation circuit, and this output is sent to the motor control circuits 16 and 17. Sent.

送り出される紙葉類19を補正する。 The motor control circuit 16 is a circuit that controls the rotational speed of the control motor 12 for the clearance correction roller, and operates the control motor 12 at high speed for a time proportional to the signal sent from the control signal generation circuit 15. As a result, the gap between the leading edge of the paper sheet corrected by this correction roller and the end of the preceding paper sheet becomes the minimum gap in terms of mechanical processing. At the same time, like the motor control circuit 16, the motor control circuit 17 also operates the control motor 10 at high speed for a period of time proportional to the signal sent from the control signal generation circuit 15. The paper sheet 19 to be picked up and sent out next time is corrected by the same distance as the distance corrected by the gap correction roller.

用し、最高処理速度を得ることが可能となる。 Further, to explain with reference to FIG. 4, the paper sheets 18 and 19 are
When the gap passes through the gap correction roller, it is corrected in the same manner as described above. At the same time, the speed of the suction belt is also controlled. The above explanation will be explained in detail according to the flow of paper sheets. Paper leaves 20, 18,
19 is sucked by the suction belt and sent out to the conveyance path with the same distance A between the ends. Since the paper sheets have different lengths, the distance between the paper sheets is not constant. The minimum gap required for mechanical processing is defined as length a, and the gaps between paper sheets 20 and 18, 18 and 19 are respectively a+
When b, a+c, b and c are allowances for mechanical processing, and it is possible to increase the processing speed by shortening the gap between paper sheets by b and c. The tip of the paper sheet 18 is detected by the detector 14, the gap between it and the previous paper sheet 20 is measured, and after the paper sheet 18 is sandwiched between the gap correction roller 11 and the idle roller 13, this measurement result is Basically, the clearance correction roller 11 rotates at high speed for a certain period of time,
The gap (a+b) between paper sheets 18 and 20 is shortened by b, and the gap becomes the minimum gap a. At the same time, the drive roller 9 also rotates at high speed for a certain period of time after suctioning the paper sheet 19, so that the suction belt runs at high speed for a certain period of time, and the sheet sheet 19 is moved at a higher speed than when the suction belt is normally running. As a result, the gap between the paper sheets 18 and 19 remains unchanged (a+c). Next, paper sheets 19'
The leading edge of the sheet is detected by the detector 11, and the gap (a+
c) is shortened by c to become the minimum clearance a. By performing the above correction on paper sheets that are continuously fed, the gap between the front and rear sheets becomes a certain minimum value a, eliminating waste during mechanical processing, and making it easier for the paper sheets to be processed. On the other hand, it is possible to utilize the maximum capacity of the machine and obtain the highest processing speed.
