Description

  The present invention relates to a paper handling apparatus that rolls a paper bundle in which a plurality of papers are superimposed so as to be easily separated into papers one by one.

  Conventionally, the usage statement information of a credit card or a mobile phone is printed on a predetermined sheet of usage statement information and enclosed in an envelope and sent to the user. Most telephone companies enclose printed materials with advertisement information in an envelope together with a usage statement and send them to users.

  Also, in direct mail and business mail in which printed materials with advertisement information are enclosed in envelopes, multiple printed materials are enclosed in envelopes and sent in combinations according to the destination of direct mail or business mail. .

  Thus, when enclosing a plurality of printed materials in one envelope, it is necessary to combine a plurality of printed materials enclosed in one envelope first. Conventionally, when combining a plurality of printed materials, it is possible to feed the combined printed materials one by one from a feeder provided for each type, and sequentially superimpose them on a conveyance path for conveying the fed printed materials. This is done, and a plurality of printed materials are combined (for example, refer to Patent Document 1). Therefore, a plurality of printed materials to be fed are superimposed and supplied to each feeder that feeds printed materials one by one.

The plurality of printed materials combined on the conveyance path are then sealed in one envelope.
Japanese Patent Laid-Open No. 7-1861

  However, as described above, when a plurality of sheets such as printed matter are overlapped, the overlapped sheets are brought into close contact with each other by the action of static electricity or the like, and a plurality of sheets are fed at once when applied to the feeder. In other words, so-called double feed may occur. Therefore, when a plurality of stacked sheets are loaded on the feeder, the sheet stack on which the plurality of sheets are stacked is swung so as to be manually waved to separate the sheets one by one. However, since this is a manual operation, there is a limit to the number of sheets that can be rolled at one time, and the number of sheets that can be applied to a single feeder is limited. When the number of feeders to be applied is large, there is a problem that work efficiency is remarkably lowered.

  The present invention has been made in view of the problems of the prior art as described above, and is a paper-making apparatus capable of separating a plurality of stacked sheets so as to be easily separated without manual intervention. The purpose is to provide.

In order to achieve the above object, the present invention provides:
A paper-making device that easily separates a plurality of stacked sheets,
A handling member that moves in the overlapping direction of the plurality of sheets while abutting against one end of the plurality of stacked sheets;

  In the present invention configured as described above, when the handling member moves in the stacking direction of the plurality of sheets while abutting against one end of the plurality of stacked sheets, the handling member among the plurality of sheets Is in contact with one end of the sheet, and the one end is curved downstream in the moving direction of the handling member. Thus, the paper with which the handling member comes into contact sequentially changes in the moving direction of the handling member as the handling member moves. The paper whose one end no longer comes into contact with the handling member will not bend at its one end, so the paper whose one end is curved when the handling member comes into contact with the paper, and the upstream of the handling member in the movement direction. A space is created on one end side between the stacked sheets. Then, air is blown from one end side between these sheets by the air blowing means that moves in the overlapping direction of the plurality of sheets together with the handling member. Then, the blown air escapes from the space formed between these sheets to the opposite side through between the sheets, thereby separating a plurality of sheets sequentially.

  As described above, in the present invention, the handling member that moves in the overlapping direction of the plurality of sheets while contacting one end of the plurality of stacked sheets, and the overlapping direction of the plurality of sheets together with the handling member The paper whose one end is curved on the downstream side in the movement direction of the handling member due to the handling member abutting among the plurality of sheets and the paper that is superimposed on the upstream side in the movement direction of the handling member with respect to this paper Air blowing means for blowing air from the one end side between the air and the air blown from the air blowing means against the sheet having one end curved toward the downstream side in the moving direction of the handling member and this sheet.

  Hereinafter, a papermaking method using the papermaking apparatus 1 configured as described above will be described.

  FIG. 3 is a diagram showing a state in which a plurality of printed materials 40 are placed on the placement table 30 of the paper making apparatus 1 shown in FIG.

  As shown in FIG. 3, the plurality of superimposed printed products 40 have one end in contact with the mounting table 30 in a region surrounded by the end surface support members 20 a and 20 b and the clamping plates 10 a and 10 b of the mounting table 30. The both ends are supported by the end surface support members 20a and 20b. At this time, since the hole 33 is formed in the region surrounded by the end surface supporting members 20a, 20b and the pressing members 10a, 10b of the mounting table 30, the printed matter 40 placed in this region is a part of each. Will be exposed from the hole 33.

  FIG. 4 is a view for explaining the operation when the printed material 40 placed on the placement table 30 is spread by the paper making apparatus 1 shown in FIG. 1, and is a view seen from the end face supporting member 20b side. is there.

  As shown in FIG. 4, a plurality of superimposed printed materials 40 are placed on the mounting table 30 such that one end of the printed material 40 abuts the mounting table 30, and a pair of sandwiching plates as described above. When the air supply device 61 and the air supply nozzle 62 are driven by being sandwiched from the front and back by 10a and 10b, air is sent from the air supply device 61 to the air supply nozzle 62, and air is discharged from the air outlet 64 of the air supply nozzle 62. At the same time, the handling plate 65 and the air supply nozzle 62 begin to move along the support shaft 63 from the clamping plate 10a side to the clamping plate 10b side.

  Since the handling plate 65 is in contact with one end portion of the printed matter 40 that is in contact with the mounting table 30, when the handling plate 65 moves along the support shaft 63 from the clamping plate 10a side to the clamping plate 10a side, FIG. As shown, one end of the printed material 40 in contact with the handling plate 65 is curved downstream in the movement direction of the handling plate 65. In this way, the printed material 40 in contact with the handling plate 65 is sequentially changed from the printed material 40 on the holding plate 10a side to the printed material 40 on the holding plate 10b side as the handling plate 65 moves. The printed material 40 whose one end no longer comes into contact with the handling plate 65 is not curved at its one end, so that the printed material 40 whose one end is curved when the handling plate 65 comes into contact with the printed material 40 and the printed material 40 are handled. A space is formed on one end side where the handling plate 65 comes into contact with the printed matter 40 superimposed on the upstream side in the movement direction of the plate 65. Note that the lower surface of the sandwiching plate 10 b is bent downstream in the movement direction of the handling plate 65 and the air supply nozzle 62 so as not to prevent the printed matter 40 from being bent by the handling plate 65. Further, since the sandwiching plate 10 b is fixed to the support plate 31 b by the fixed shaft 34, only one end portion of the printed matter 40 with which the handling plate 65 abuts is curved in the moving direction of the handling plate 65.

  The air discharged from the air supply nozzle 62 is blown onto the printed matter 40 through the hole 65 a of the handling plate 65. At this time, the hole 65a of the handling plate 65 is formed in a region on the lower side with respect to the perpendicular drawn from the upper end of the handling plate 65 in the lower side portion of the square shape of the handling plate 65. Therefore, the air discharged from the air supply nozzle 62 is blown onto the printed matter 40 without hitting the upper end portion of the handling plate 65. Further, in the region where the air discharged from the air supply nozzle 62 is blown, as described above, the printed matter 40 whose one end is curved by the handling plate 65 coming into contact with the printed matter 40 and the handling plate 65 of the handling plate 65. A space is formed on one end side where air is blown between the printed matter 40 and the printed material 40 superimposed on the upstream side in the movement direction, and the air discharged from the air supply nozzle 62 is blown into the space.

  The air 40 discharged from the air supply nozzle 62 includes a printed material 40 whose one end is curved by the handling plate 65 coming into contact with the printed material 40 superimposed on the upstream side of the printed material 40 in the moving direction of the handling plate 65. When air is blown into the space generated on one end side of the space, the air blown into the space is a printed product 40 whose one end is curved by the handling plate 65 coming into contact with the printed product 40. Passing between the printed material 40 superimposed on the upstream side in the moving direction and coming out to the opposite side of the mounting table 30, whereby the printed material 40 whose one end is curved by the contact of the handling plate 65, and the printed material 40 On the other hand, the air 40 blown from the air supply nozzle 62 with the printed matter 40 superimposed on the upstream side in the moving direction of the handling plate 65. Therefore, once separated. At this time, since the sandwiching plate 10a is supported by the support plate 31a via the spring 32, the spacing between the sandwiching plates 10a and 10b is increased by the amount of air that has entered between the plurality of printed materials 40. It does not prevent the printed matter 40 from being separated.

  Then, the handling plate 65 and the air supply nozzle 62 are moved in the overlapping direction of the printed matter 40 by the support shaft 63, so that each of the plurality of printed matter 40 placed on the placement table 30 is handled as described above. One end of the plate 65 abutting against the handling plate 65 is curved downstream in the movement direction of the handling plate 65, and the curved printed material 40 is superimposed on the upstream side in the movement direction of the handling plate 65 with respect to the printed material 40. Air is sequentially blown from the air supply nozzle 62 into the space formed between the printed product 40 and the air blown from the air supply nozzle 62 passes between the plurality of printed products 40 and escapes to the opposite side. All of the plurality of printed materials 40 placed on the placement table 30 are once separated from each other and placed on the placement table 30. So that the printed material 40 is loosened.

  FIGS. 5A and 5B are views showing other forms of the handling plate and the air supply nozzle used in the paper making apparatus 1 shown in FIG. 1, wherein FIG. 5A is an external perspective view, and FIG. 5B is a side view. is there.

  As shown in FIG. 5, the handling plate 165 in this embodiment has a shape that is bent in the left-right direction and bent in a dogleg shape in the up-down direction. The air supply nozzle 162 has a plurality of air outlets 64 at its tip, and the plurality of air outlets 64 are mounted in a region surrounded by the end surface support members 20a and 20b of the mounting table 30 and the sandwiching plates 10a and 10b. On the lower side of the letter-shaped upper side of the handling plate 165 and on the lower side toward the upper side of the letter-shaped side. It is arranged so that air is discharged along.

  Hereinafter, a paper-making method when the paper-making plate 165 and the air supply nozzle 162 configured as described above are used in the paper-making device 1 shown in FIG. 1 will be described.

  FIG. 6 is a view for explaining a paper-making method when the paper-making plate 165 and the air supply nozzle 162 shown in FIG. 5 are used in the paper-making device 1 shown in FIG. 1, from the end surface supporting member 20b side. FIG.

  As shown in FIG. 6, a plurality of superimposed printed materials 40 are placed on the mounting table 30 such that one end portions of the printed materials 40 are in contact with the mounting table 30, and a pair of sandwiching plates as described above. When the air supply unit 61 and the air supply nozzle 162 are driven by being sandwiched from the front and back by 10a and 10b, the air is sent from the air supply unit 61 to the air supply nozzle 162, and the air is discharged from the air outlet 64 of the air supply nozzle 162. At the same time, the handling plate 165 and the air supply nozzle 162 begin to move along the support shaft 63 from the clamping plate 10a side to the clamping plate 10b side.

  Since the handling plate 165 is in contact with one end portion of the printed matter 40 that is in contact with the mounting table 30, when the handling plate 165 moves along the support shaft 63 from the clamping plate 10 a side to the clamping plate 10 a side, FIG. As shown, one end of the printed product 40 in contact with the handling plate 165 is curved downstream in the movement direction of the handling plate 165. As described above, the printed matter 40 that the handling plate 165 contacts changes sequentially from the printed matter 40 on the sandwiching plate 10a side to the printed matter 40 on the sandwiching plate 10b side as the handling plate 165 moves. The printed material 40 whose one end no longer comes into contact with the handling plate 165 is not curved at its one end. Therefore, the printed material 40 whose one end is curved when the handling plate 165 comes into contact with the printed material 40 and the printed material 40 are handled. A space is generated on one end side where the handling plate 165 contacts with the printed matter 40 superimposed on the upstream side in the moving direction of the plate 165. Note that the lower surface of the sandwiching plate 10 b is bent downstream in the movement direction of the handling plate 165 and the air supply nozzle 162 so as not to prevent the printed material 40 from being bent by the handling plate 165.

  The air discharged from the air supply nozzle 162 is blown toward the upper side portion along the lower side portion of the letter-shaped shape of the handling plate 165, and is further applied to the upper side portion of the letter-like shape. It will flow along, and will be sprayed to the space produced as mentioned above.

  The air 40 discharged from the air supply nozzle 62 includes a printed product 40 whose one end is curved by the handling plate 165 coming into contact with the printed product 40 superimposed on the printed material 40 on the upstream side in the moving direction of the handling plate 165. When the air blown into the space formed on one end side of the space, the air blown into the space is a printed product 40 whose one end is curved by the handling plate 165 coming into contact with the printed product 40. Passing between the printed material 40 superimposed on the upstream side in the moving direction and coming out to the opposite side of the mounting table 30, whereby the printed material 40 whose one end is curved by the contact of the handling plate 165, and the printed material 40 On the other hand, the printed matter 40 superimposed on the upstream side in the moving direction of the handling plate 165 is blown from the air supply nozzle 162. Once separated by vignetting air. At this time, since the sandwiching plate 10a is supported by the support plate 31a via the spring 32, the spacing between the sandwiching plates 10a and 10b is increased by the amount of air that has entered between the plurality of printed materials 40. It does not prevent the printed matter 40 from being separated.

  Then, the handling plate 165 and the air supply nozzle 162 are moved in the overlapping direction of the printed matter 40 by the support shaft 63 so that each of the plurality of printed matter 40 placed on the placing table 30 is handled as described above. One end of the plate 165 that contacts the handling plate 165 is curved downstream in the movement direction of the handling plate 165, and the curved printed product 40 is superimposed on the upstream side in the movement direction of the handling plate 165 with respect to the printed product 40. Air is sequentially blown from the air supply nozzle 162 into the space formed between the printed product 40 and the air blown from the air supply nozzle 162 passes through the plurality of printed products 40 to the opposite side. All of the plurality of printed materials 40 placed on the table 30 are once separated from each other, So that placing a plurality of sheets of printed material 40 has is loosened.
