Abstract

PURPOSE:To smoothly convey even a curled sheet of paper by separating a back faced sheet of paper among sent-in sheets of paper at a gate, bringing said sheet of paper into pressure contact with a guide roller and conveying it into an inverting means and, then, reversing said guide roller and discharging said sheet of paper. CONSTITUTION:Sheets of paper which are sent in are distinguished between the front side and back side by a distinguishing part 1, and sent out in between rollers 18, 21 by means of a conveying roller 3. When a sheet of paper is faced down, a gate 8 is positioned as shown in the figure, and the sheet of paper is brought into pressure contact with the vane of a guide roller 12, sent into a reversing part 10 and stopped by a stopper 11. Then, the rear end of the sheet of paper is conveyed in the opposite direction by the vane 14 of a guide roller 12, and discharged out in the direction of the arrow A by a confluent guide 13 and by means of rollers 19, 23. When a sheet of paper is faced up, the gate 8 is rotated leftward around a shaft 7, and the sheet of paper is discharged in the direction of the arrow A via endless belts 5, 6 and through the confluent guide 13. The length of the conveying passages for both front faced and back faced sheets of paper are kept equal, thereby, even curled or dog-eared sheets of paper can be securely inverted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a paper sheet conveyance processing device, and in particular, during the conveyance of paper sheets, the first and second surfaces of the conveyed paper sheets are The present invention relates to a paper sheet processing device having a sheet reversing means that enables the reversal of paper sheets.

[Conventional technology]

Conventionally, as a paper sheet processing apparatus having this kind of paper sheet reversal feeding function, for example, as described in Japanese Patent Application Laid-Open No. 198250, an endless belt is used to turn the rear end of the conveyed paper sheet to the leading edge. There is a structure that

In this structure, the conveying speed of the endless belt is configured to be the same as the circumferential speed of the pulley shaft with which the conveying belt engages. Further, for paper sheets that are not to be reversed, the approach stop member provided at the leading end in the feeding direction is retracted from that position and does not come into contact with the leading end of the sheet, so that the sheet is transported without being reversed.

[Problem that the invention seeks to solve]

However, with this conventional structure, if there is a curl or crease at the leading edge of a paper sheet that is not to be flipped, or if there is a curl or crease at the trailing edge of a paper sheet that should be flipped, it is not possible to smoothly move the paper to the next one. It is considered that sheets with an abnormally short length in the conveying direction, such as sheets folded in half, cannot be conveyed, and there is a risk of jamming without being conveyed to the conveyance path.

Furthermore, it is necessary to match the conveyance speed of the endless belt to the circumferential speed of the pulley shaft, which complicates the structure.

An object of the present invention is to provide a paper sheet capable of reliably reversing the first side and second side of the paper sheet even if there is a dimensional abnormality in the self-transportation of the paper sheet or deformation of the paper sheet. The objective is to provide a similar processing device.

[Means to solve problems]

The above object is to provide a guide roller near the paper sheet reversing means for smoothly carrying the paper sheets to be reversed into the reversing means and smoothly carrying them out, This is accomplished by providing a flexible member that presses the material on the incoming roller when it is carried into the reversing means, and on the outgoing roller when it is carried out.

[Effect]

The guide roller is provided at a position where it comes into contact with the paper sheet and presses the paper sheet against the carry-in roller when the paper sheet enters the reversing means, so that the generated frictional conveying force of the carry-in roller prevents curling and curling. The folded paper sheet smoothly enters the reversing means, and the guide roller moves the rear end of the paper sheet from the input roller side to the output roller side in the reversing means, and Paper sheets B that are curled or folded due to the frictional conveying force of the carry-out roller generated by being moved to the carry-out roller side and placed in a position where it is pressed against the carry-out roller can be easily moved between the carry-out roller and the guide roller. It can be clipped into the assembly section and transported smoothly.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In the following explanation, paper sheets facing the first side refer to all paper sheets that do not require flipping, and paper sheets facing the back side facing the second side refer to all paper sheets that do not require flipping. refers to paper sheets that require flipping.

FIG. 1 is a sectional view illustrating an embodiment of the present invention, FIG. 2 is a plan view of the main part of FIG. 1, and FIG. 3 is a perspective view of FIG. 2. In this embodiment, paper sheets are inputted one by one from an inlet 2 of the discrimination section 1, and a pair of rollers 3 is driven by a motor (not shown) to be conveyed to an outlet 4 of the discrimination section 1. In this embodiment, the processing device includes a first conveyance path structure formed by a combination of conveyor belts 5 and 6, a partition section 8 located on the input side of the first conveyance path and rotatable about a shaft 7; and a second conveyance path for conveying one of the sheets sorted by the sorting section 8 (in this example, a face-down sheet to be reversed); Carrying guide frame 9 for smoothly reversing the connected and reversed paper sheets
, carry-in roller 21, carry-out guide frame 1o, approach stop member 1
1, a guide roller 12, a carry-out roller 23, a merging guide 13, and the like. One or more flexible members 14 are wrapped around the outer peripheral surface of the guide roller 12, and the conveyor belt 5 is wound endlessly around pulleys 15 to 17. The conveyor belt 6 is wound endlessly around pulleys 18, 15, 17, 16° and 19,20, and the pulleys 15, 16, and 17 are all wound around the conveyor belt 5. Each pulley rotates in the direction of the arrow. Here, the distance from the outer circumferential surface of the roller 12 to the entry stop member 11 is set to the guide roller so that it is equal to or somewhat longer than the length in the conveying direction of the face-down sheet, and the flexible member 14 The distance from the outer periphery of the paper sheet to the entry stop member 1 is configured to be smaller than the length of the paper sheet facing down in the conveyance direction. Reference numeral 21 denotes a carry-in roller for carrying paper sheets facing down between the carry-in guide frame 9 and the carry-out guide frame 10.

Next, the operation of this embodiment will be explained with reference to FIGS. 1 to 6. If the discrimination section 1 in FIG.
It is located as shown by the solid line in the figure.

Therefore, these paper sheets facing down are separated from paper sheets facing front by the sorting section 8, and are reversed by the following operation.

FIGS. 1 to 3, which explain this reversing operation, show the side end 22a and the leading end 22b of the paper sheet 22 when the paper sheet 22 facing backward enters the reversing section.

Since the outer circumferential surface position of the flexible member 14 attached to the outer circumferential surface of the guide roller 12 is complicated with the carry-in roller 21 and the carry-in guide frame 9, one paper sheet 22 is attached to the flexible member 14. When it comes into contact with the carry-in roller 2, it receives a forced deformation force and
Pressed to 1. Since the paper sheets are forcibly deformed in this way, their rigidity increases in appearance, and even paper sheets that are curled or folded can move smoothly within the guide frames 9 and 10. Finally, it becomes possible to reach the entry stop member 11. Figure 4 shows the guide frame 9°10
It shows a pull in which the paper sheet 22 rushes inside.

In FIG. 4, the distance from the outer circumferential surface of the flexible member 14 to the path stop member 11 is shorter than the length of the sheet 22 in the conveyance direction, and as the flexible member 14 rotates, The rear end 22C of the paper sheet moves from the thick solid line as shown by the two-dot chain line 22d and is pressed against the delivery roller 23. Next, as shown in FIG.
be forced to. At this time, paper sheets 22 and delivery roller 23
It is smoothly conveyed along the merging guide 13 due to the frictional force between the two.

Next, the front and back sides of the paper sheet are discriminated by the discriminating unit 1, and if it is determined that the paper sheet is the front side, the sorting unit 8 is moved to the position 8' in FIG. Rotate clockwise. Therefore, these front-facing paper sheets are transported by the conveyor belts 5 and 6.
and conveyed to the first merging guide 13.

Therefore, all of the paper sheets carried out from the first merging guide section 13 are turned into paper sheets with the same orientation as front-facing paper sheets, and are conveyed to a post-processing section (not shown).

In addition, the length of each conveyance path is adjusted so that the time required for transporting front-facing paper sheets from the sorting section 8 to the merging section 13 is approximately equal to the transport time including reversing operations for reverse-facing paper sheets. , the conveyance speed, and the rotational speed of each roller are set, so when the paper sheets that have been sorted and reversed in the 1 sorting section 8 are conveyed from the merging guide 13 to the post-processing section, the distance between the sheets facing the front side is There is no variation and no inconvenience in post-processing.

Next, FIG. 6 shows a case where a paper sheet 22 that is not turned over and has an abnormally short length in the transport direction, such as a paper sheet 22 that is folded in two, enters the classification section 1 and is transported through the sorting section 8'. The state of paper sheets 22 is shown. Since such paper sheets usually cause problems in the post-processing section, they are sorted out by a sorting means (not shown) before reaching the post-processing section. However, as shown in this figure, the distance between the end point of the clamping by the clamping rollers 3 and the starting point of the clamping by the conveyor belts 5 and 6 is sufficiently 4 +
By doing so, even paper sheets whose length in the transport direction is abnormally short can be smoothly transported.

In addition, in the above-illustrated embodiment, the winding method of the belt constituting each conveyance path is not limited to the illustrated example, and the size of the paper sheets to be handled, such as the feeding direction and length of the paper sheets, etc. Needless to say, the design can be changed as appropriate depending on the properties etc.

Furthermore, it goes without saying that the position of the sorting section, the position of each roller, the position of the guide frame, the position of the entry stop member, etc. can be arbitrarily selected according to the properties of the paper sheets to be handled.

FIG. 7 shows the carry-in roller 21, guide frames 9, 10, guide roller 12. In FIG. 2, which shows a second embodiment regarding the arrangement of the carry-out rollers 23, the carry-in roller 21 and the carry-out roller 23 are sandwiched between the guide rollers 12, whereas in FIG. 12 to carry-in roller 2
1. A particular difference is that they are intertwined by being sandwiched between them by the carry-out rollers 23. Therefore, the carry-in guide frame 9. The shape and mounting position of the carry-out guide frame 10 in FIG. 2 and FIG. 7 are also different. However, the carry-in roller 21. The frictional conveying force of the carry-out roller 23 and the smooth reversing operation obtained are exactly the same in FIG. 2 and FIG. 7.

Additionally, a flexible member 1 attached to the circumference of the guide roller 12
The shape, quantity, size, etc. of 4 are not limited to those shown in FIG. 1, for example.

As shown in FIG. 8, a flexible member 14 made of nylon or other thin wire is used, and the flexible member 14 is planted diagonally at equal intervals around the circumference of the guide roller 12, or as shown in FIG. In some cases, the flexible member 14 is made of a material such as a belt and is provided at equal intervals around the circumference of the guide roller 12, or as shown in FIG. One possible option is to use a material and plant it directly on the shaft. The shape, number, size, etc. of these flexible members 14 can be arbitrarily selected depending on the conditions such as the rigidity, curling, and folding of the paper sheets to be handled, but their effects and functions may vary. is the same as the first and second embodiments,
Of course, the design can be changed as appropriate to avoid damaging the paper sheets being handled.

According to the present invention, it is possible to reversely convey paper sheets while conveying them, and even when conveying a mixture of front-facing and reverse-facing paper sheets, the conveyance order and conveyance interval are kept constant, and all Paper sheets can be sent out with the paper sheets facing up, so that processing such as stacking and storing paper sheets in the post-processing section becomes easy and accurate. In addition, when reversely conveying paper sheets facing the wrong side, the apparent rigidity of the paper sheet can be increased using the guide roller, so even sheets with curls or folds can be reliably turned over. It has the effect of

Furthermore, even when paper sheets with abnormally short lengths in the transport direction are mixed, it is possible to smoothly transport them to the post-processing section.

〔Effect of the invention〕

As explained above, according to the present invention, even if there is an abnormality in the dimensions of the paper sheet in the conveying direction or deformation of the paper sheet, it is possible to reliably turn the paper sheet upside down, and the entire mechanism The structure can be simplified.
