The collated bundle T is discharged in the Y direction with the leading end T-1 side in the discharge direction (Y direction) covered by the origami s. In the present embodiment, in the state in which one end s-1 (right end as viewed from the discharge direction) along the discharge direction of the origami s is substantially aligned with the end t-1 of the plurality of folding leaflets t The sheet feeding position along the X direction of the origami s can be adjusted so as to eject T.

  FIG. 4 is a view for explaining how to fold the newspaper P input to the collating / inserting device 100 through the input unit 21 of the newspaper supply mechanism 20. As shown in FIG. The newspaper P is inserted into the input unit 21 in a standing position in which the fold line P-1 shown in FIG. 4C is directed downward and the fold line P-2 is on the right side when viewed from the front of the apparatus.

  As shown in FIG. 4 (a), the newspaper is folded in half as shown by a broken line in the center from a state in which a plurality of newspaper sheets of A1 size are stacked, and as shown in FIG. 4 (b) A state in which a plurality of single-folded newspaper sheets are folded in half like a broken arrow in the center (in a state of being folded in four) (a newspaper folded into approximately A3 size) (FIG. It is input to the part 21. The newspaper P input to the input unit 21 is extracted downward with the crease P-1 at the top.

  Next, the operation in the collating mode by the collating and inserting apparatus 100 described above will be described. Prior to the operation, the operator inserts the folding flap t into each of the sheet feeding trays 2 and 2a of the collating mechanism 10.

  Then, when a processing command in the collating mode is input through the operation input panel (not shown), the folding flaps t are fed one by one to the conveyance path 3 from the predetermined sheet feeding tray 2 and overlapped and overlapped. A plurality of folded leaflets t are conveyed downward via the transport path 3, and a collated bundle T in which the plurality of folded leaflets t are sandwiched by the origami s is discharged from the discharge port 15.

  The collated bundle T discharged from the discharge port 15 is flying and conveyed in the Y direction through the free space F of the direction conversion unit 60, falls onto the discharge conveyor 39 traveling in the Y direction, and travels by the discharge conveyor 39 It is sequentially discharged to the stacking and aligning mechanism 40 and stacked. At this time, an X-direction strike plate and a Y-direction strike plate (not shown) provided in the accumulation and alignment mechanism 40 are operated to align the end sides of the collected bundle T.

  When a predetermined number of collated bundles T are discharged from the discharge port 15 and the end sides are aligned while stacking collated bundles T by the accumulation and alignment mechanism 40, the operation of the collating mechanism 10 is stopped, and the predetermined number The collated bundle T is discharged in the X direction and transferred to a lifter (not shown). At this time, since the plurality of sets of collated bundles T are horizontally moved in the X direction different from the stacking direction, the posture of the collated bundles T is less likely to collapse.

  Next, the operation in the collating and inserting mode by the above collating and inserting apparatus 100 will be described. In addition, since the operation | movement at the time of a centering-in mode is the same as a collation / centering-in mode except only there is no collation operation | movement of a folding | covering, the description is abbreviate | omitted here.

  Prior to the operation in the collating / interlacing mode, the operator inserts the folding leaflets t into the respective sheet feeding trays 2 and 2a of the collating mechanism 10, and inserts a plurality of newspapers P into the inserting portion 21 of the newspaper supplying mechanism 20. throw into.

  In this state, when a processing command in the collating / inserting mode is input via the operation input panel (not shown), the newspaper supply mechanism 20 takes out a part of the newspaper P one by one, as in the collating mode described above. The collated bundle T is created and discharged from the discharge port 15. At this time, the processing speed and the extraction timing of the newspaper P are adjusted so that the timing of sending the newspaper P to the discharge conveyor 39 and the timing of discharging the doubled bundle T toward the discharge conveyor 39 match.

  When the newspaper P is fed to the newspaper transport / opening mechanism 30 by the newspaper supply mechanism 20, the newspaper P is transported in the X direction, and the free space of the direction conversion unit 60 downstream of the newspaper transport / opening mechanism 30 in the X direction. It is sent to F. At this time, the newspaper P is flying and transported through the free space F, and the upper portion P1 and the lower portion P2 of the newspaper P are opened. Then, the collated bundle T sent into the free space F in accordance with the transport timing of the newspaper P is inserted into the gap between the upper portion P1 and the lower portion P2, and the paper sheet K is formed on the discharge conveyor 39. Dropped and placed.

  In this way, the paper sheet K in which the collated bundle T is inserted in the newspaper P is sent to the accumulation / alignment mechanism 40 via the discharge conveyor 39, and the edges are aligned while being stacked. When the predetermined number of sheets K are stacked, the predetermined number of stacked sheets K (not shown) are discharged in the X direction and transferred to a lifter (not shown).

  As described above, according to the collating and inserting apparatus 100 of the present embodiment, in addition to the collating mode and the inserting mode, the operation in the collating and inserting mode becomes possible. In the collated / interleaved mode, the newspaper P is opened and conveyed, and at the same time, the collated bundle T is created to be inserted in, so the interlacing into the newspaper P becomes possible simultaneously with the collating of the folding leaflets, K can be neatly arranged. For this reason, for example, it is also possible to insert in the newspaper P a collated bundle T in which only a plurality of folding leaflets t are stacked without using the origami s.

  Therefore, according to the present embodiment, the workload on the operator can be reduced, and the processing efficiency can be improved. Furthermore, according to the present embodiment, it is not necessary to insert a collated bundle created by a collating machine as in the prior art into an inserter (an apparatus for inserting the collated bundle into a newspaper), thereby reducing the operation cost by the operator. Can.

FIG. 5 is an enlarged schematic view of the newspaper transport and opening mechanism 30. As shown in FIG.
The newspaper P taken out from the input unit 21 of the newspaper supply mechanism 20 is guided vertically downward with the fold line P-1 at the top, and the upper feed belt 25a disposed between the input unit 21 and the newspaper conveyance / opening mechanism 30. And the lower feed belt 25b (hereinafter, may be collectively referred to as a feed belt pair 25), it is fed to the newspaper transport and opening mechanism 30. At this time, the newspaper P is sandwiched between the upper feed belt 25a and the lower feed belt 25b, is curved toward the front of the device, is conveyed in the Y direction, and is converted into a substantially horizontal attitude, so that the newspaper It is dropped and placed on the transport conveyor 31 (first transport unit) of the transport / opening mechanism 30.

  The newspaper transport and opening mechanism 30 has a transport conveyor 31 disposed on the front side of the newspaper supply mechanism 20 below the newspaper discharge unit 25 c of the feed belt pair 25. The conveyor 31 has a structure in which an endless conveyor belt 34 is wound around a pair of belt rollers 32 and 33 which are separated in the X direction and extend in parallel to each other in the Y direction and stretched in the X direction.

  The transport conveyor 31 causes the top surface 34 a of the transport belt 34 (the top surface of the part traveling with the posture in which the surface of the transport belt 34 faces upward) to travel in the X direction along a substantially horizontal plane. The transport conveyor 31 is provided such that the edge of the upper surface 34 a of the transport belt 34 on the newspaper supply mechanism 20 side is inclined slightly upward from the front edge in the Y direction. The upper surface 34 a of the transport belt 34 of the transport conveyor 31 functions as a surface on which the newspaper P which has been sent from the newspaper supply mechanism 20 and dropped falls.

  The upper surface 34 a of the conveyer 31 is fed onto the conveyer 31 via the feed belt pair 25 of the newspaper supply mechanism 20 at a position opposite to the front end edge along the X direction of the conveyer belt 34. An abutment plate 35 is provided to abut the tip of the newspaper P in the Y direction (fold P-1). In FIG. 5, in order to make the transport conveyor 31 easy to see, the abutment plate 35 is shown by a broken line.

  The abutment plate 35 abuts the tip of the newspaper P fed in the Y direction, and stops the transportation of the newspaper P in the Y direction. The newspaper P having its tip end butted against the abutment plate 35 falls onto the upper surface 34 a of the transport belt 34 by its own weight. The abutment plate 35 is attached in an inclined manner with its upper end inclined rearward.

  When the conveyor 31 travels in the X direction, the newspaper P fed from the newspaper supply mechanism 20 and dropped onto the upper surface 34 a of the conveyor belt 34 is 90 ° converted in the conveyance direction and conveyed in the X direction.

  The newspaper transport and opening mechanism 30 includes an adsorption rotation member 37 and a separation plate 38 which project into the free space F of the direction conversion unit 60 adjacent to the downstream end of the transport conveyor 31 in the transport direction (X direction). . The suction and rotation member 37 and the separation plate 38 are disposed at a position facing the front of the discharge port 15 of the collating mechanism 10. More specifically, in the suction rotation member 37 and the separation plate 38, the collated bundle T discharged in the Y direction from the discharge port 15 of the collation mechanism 10 through the discharge roller pair 14 is on the lower surface of the separation plate 38. It is positioned so as to be fed between the upper part P1 and the lower part P2 of the newspaper P along.

  The suction and rotation member 37 is disposed below the upper surface 34 a of the conveyance belt 34 at a position offset to the rear of the conveyance belt 34. The suction and rotation member 37 applies a negative pressure to the lower portion P2 (FIG. 4c) of the newspaper P which has passed through the transport conveyor 31, sucks it, and pivots in a direction (downward) away from the transport surface. The suction and rotation member 37 operates every time the newspaper P is transported, and applies a negative pressure to the lower portion P2 for a short time at least when the lower portion P2 of the newspaper P is separated from the upper portion P1. That is, the lower portion P2 of the newspaper P which is sucked downward by the suction and rotation member 37 and opened downward is further opened downward by its own weight after the negative pressure by the suction and rotation member 37 is eliminated.

  The separation plate 38 is disposed adjacent to the downstream end of the transport conveyor 31 in the transport direction (X direction) at a position offset to the rear of the transport belt 34, and the upper portion P1 of the newspaper P passing through the transport conveyor 31 Support from below. The separation plate 38 is disposed above the suction and rotation member 37 at substantially the same height position as the conveyance surface of the conveyance conveyor 31. That is, the separation plate 38 functions to separate the upper portion P1 and the lower portion P2 of the newspaper P in cooperation with the suction and rotation member 37 which sucks and rotates the lower portion P2 of the newspaper P.

  That is, when the leading end in the conveyance direction of the newspaper P placed on the upper surface 34 a of the conveyance belt 34 and conveyed in the X direction is separated from the downstream end of the conveyance conveyor 31 and approaches the free space F, The lower portion P2 of the newspaper P is sucked by the suction and rotation member 37 and opened downward at a position offset to the rear. At this time, the upper part P1 of the newspaper P moves above the separating plate 38, and the upper part P1 and the lower part P2 of the newspaper P are separated. Then, at the timing when the upper part P1 and the lower part P2 of the newspaper P are opened, the collated bundle T is discharged from the discharge port 15 of the collating mechanism 10 and inserted between the upper part P1 and the lower part P2. Ru.

  A discharge conveyor 39 (a second conveyance unit, a discharge unit) is provided below the separation plate 38 (the insertion position for inserting the gathering bundle T into the newspaper P) on the downstream side of the conveyance conveyor 31 along the X direction. It is done. Similar to the transport conveyor 31, the discharge conveyor 39 is an endless belt wound around a pair of belt rollers and stretched, and the upper surface 39a of the discharge conveyor 39 is provided to run in the Y direction. That is, the moving direction of the paper sheet K by the discharge conveyor 39 is different by about 90 ° from the conveyance direction of the newspaper P by the conveyance conveyor 31.

  The discharge conveyor 39 is disposed at a position where the upper surface 39 a is lower than the upper surface 34 a of the transport conveyor 31. Therefore, the newspaper P flying and transported in the X direction by the transport conveyor 31 falls onto the upper surface 39 a of the discharge conveyor 39. In the meantime, as described above, the collating bundle T is inserted between the upper portion P1 and the lower portion P2 of the newspaper P while being dropped from the transport conveyor 31 to the discharge conveyor 39, and the paper sheet K is formed. That is, the paper sheet K falls onto the upper surface 39 a of the discharge conveyor 39.

  FIG. 6 is an external perspective view of the direction conversion unit 60 as viewed obliquely from above. FIG. 7 is a schematic view showing the configuration of the direction conversion unit 60 including the pressing plate 64 (pressing member) according to the first embodiment. A conveyance guide 66 parallel to the XY plane is provided between the conveyance conveyor 31 and the discharge conveyor 39. Hereinafter, the configuration and operation of the direction conversion unit 60 will be described with reference to FIGS. 6 and 7.

  The direction changing unit 60 has a butting wall 62 (abutment member) for abutting the tip (fold P-2) of the newspaper P fed into the free space F by the transport conveyor 31 in the X direction. Further, the direction conversion unit 60 is capable of abutting against the rear end of the newspaper P in the X direction so as to suppress the rebound (return) in the reverse direction of the newspaper P whose front end is abutted against the abutment wall 62. Have.

  The abutment wall 62 is disposed on the downstream side of the free space F in the X direction above the discharge conveyor 39, and has a flat abutment surface 62a substantially parallel to the YZ plane. The abutment surface 62a has substantially the same length along the Y direction as the tip of the newspaper P in the X direction. Also, the abutment surface 62a has a height that exceeds at least the upper surface 34a of the transport conveyor 31 along the Z direction. The abutting wall 62 abuts on the tip of the newspaper P conveyed in the X direction via the conveyer 31 and sent into the free space F in the X direction, and stops the conveyance of the newspaper P in the X direction.

  The holding plate 64 has, for example, a structure in which one metal plate is shaped and bent. The pressing plate 64 is rotatably attached to the fixed frame 61 around a pivot shaft 71 extending in the Y direction. The pressing plate 64 has an upstream inclined plate portion 72 rotatably attached at one end to the fixed frame 61 via a rotating shaft 71, a flat plate portion 74 connected to the other end of the upstream inclined plate portion 72, and a flat plate portion A downstream side inclined plate portion 76 continuous with 74 is integrally provided. The pressing plate 64 is attached to the fixed frame 61 at the center of the transport belt 34 in the Y direction so as to face the upper surface 34 a on the downstream side of the transport conveyor 31 in the X direction.

  The pressing plate 64 is disposed at the pressing position shown in the drawing in the state shown in FIG. 7 in which the newspaper P is not transported via the transport conveyor 31, and its own weight in the clockwise direction around the pivot shaft 71. It is energized. For example, in this state, a part of the pressing plate 64 (for example, the upstream inclined plate portion 72) is pressed near the downstream end of the transport conveyor 31 in the X direction. At this time, the pressing force in the clockwise direction in the figure by the pressing plate 64 can be adjusted by placing an appropriate weight 80 on the flat plate portion 74.

  The upstream inclined plate portion 72 of the pressing plate 64 is slightly inclined downward in the X direction with respect to the XY plane in a state where the pressing plate 64 is disposed at the pressing position shown in FIG. 7. Since the upstream side inclined plate portion 72 is in contact with the conveyer 31 by its own weight, when the newspaper P is conveyed in the X direction via the conveyer 31 in the state of FIG. It collides with the lower surface of the side inclined plate portion 72. Then, the pressing force due to the collision of the newspaper P acts in the direction of lifting the upstream inclined plate portion 72, and the pressing plate 64 pivots counterclockwise around the pivot shaft 71. Thus, the pressing plate 64 is pivoted to the retracted position (not shown), and the passage of the newspaper P is permitted.

  On the other hand, the downstream inclined plate portion 76 located on the tip end side of the rotation of the pressing plate 64 has its upper end against the YZ plane extending in the vertical direction with the pressing plate 64 arranged at the pressing position shown in FIG. It is slightly inclined in the X direction (free space F side) from the lower end. Further, in this state, the contact surface 78 on the free space F side of the downstream side inclined plate portion 76 is disposed on the transport path of the newspaper P. Therefore, with the rear end of the newspaper P fed into the free space F in the X direction passing through the pressing plate 64 and the pressing plate 64 returning to the pressing position shown in FIG. Even in the case where the newspaper P which is carried out bounces back and returns in the opposite direction, the rear end of the newspaper P in the X direction can be made to abut on the abutment surface 78 of the downstream side inclined plate portion 76. It can be suppressed.

  In the present embodiment, in a state where the pressing plate 64 is disposed at the pressing position shown in FIG. 7, the contact surface 78 of the downstream inclined plate portion 76 of the pressing plate 64 and the abutting surface 62 a of the abutting wall 62 The distance along the X direction is slightly larger than the width of the newspaper P in the X direction. For this reason, it is possible to almost eliminate the problem that the newspaper P whose tip collides with the abutment surface 62a of the abutment wall 62 bounces back in the reverse direction, and the stop position in the X direction of the newspaper P sent into the free space F is desired. The position can be controlled with high precision.

  Therefore, according to the present embodiment, the newspaper P sent into the free space F can be reliably stopped at a desired position, and the dropping position of the newspaper P relative to the discharge conveyor 39 can be controlled with high accuracy. Therefore, the newspaper P dropped onto the discharge conveyor 39 can be reliably carried out in the Y direction, and the direction conversion unit 60 reliably and stably carries the newspaper P without causing jamming of the newspaper P. Can be changed.

  Further, according to this embodiment, since the collated bundle T is inserted between the newspapers P fed into the free space F as described above, the insertion position of the collated bundle T along the X direction can be stabilized. The insertion position in the X direction of the collated bundle T can be made constant in all the paper sheets K. For this reason, when a plurality of sets of paper sheets K are stacked in the rear-stage stacking and aligning mechanism 40, the end portions of the plurality of sets of paper sheets K can be aligned more beautifully.

  Furthermore, according to the present embodiment, the tip of the newspaper P flying and transported through the free space F does not return in the opposite direction after colliding with the butting surface 62 a of the butting wall 62 of the direction conversion unit 60. It is possible to prevent jamming due to interference (collision) with the subsequent newspaper P fed in the direction.

  FIG. 8 is a schematic view showing the configuration of the direction conversion unit 80 including the pressing plate 82 according to the second embodiment. The direction changer 80 has substantially the same structure as the direction changer 60 described above except that the structure of the pressing plate 82 is different from that of the pressing plate 64 of the first embodiment. Therefore, the same reference numerals are given to constituent elements that function in the same manner as in the first embodiment, and the detailed description thereof will be omitted.

  The pressing plate 82 has an upstream inclined plate portion 84 provided with a rotation shaft 71 at one end, a flat plate portion 74 connected to the other end of the upstream inclined plate portion 84, and a downstream inclined plate portion 76 connected to the flat plate portion 74. Have. The upstream inclined plate portion 84 is shorter than the upstream inclined plate portion 72 of the pressing plate 64 of the first embodiment and the inclination angle thereof is increased. Further, both ends in the Y direction of the pivot shaft 71 of the pressing plate 82 are supported so as to be movable in the vertical direction (Z direction) along the slits 88 of the bracket 86 vertically provided on the fixed frame 61.

  In this embodiment, since the inclination angle of the upstream inclined plate portion 84 is made larger than that of the first embodiment, the impact force when the tip of the newspaper P conveyed in the X direction collides with the upstream inclined plate portion 84 is large. Become. Further, in the present embodiment, since the upstream inclined plate portion 84 is shortened to reduce the weight of the pressing plate 82, the pressing plate 82 is likely to jump up when the newspaper P collides. For this reason, in the present embodiment, as compared with the first embodiment, the presser plate 82 vibrates more greatly (when the newspaper P passes), as compared to the first embodiment.

  For this reason, in the present embodiment, vibration of the pressing plate 82 is suppressed by supporting the pivot shaft 71 of the pressing plate 82 so as to be vertically movable along the slits 88. That is, when the pressing plate 82 of the second embodiment is used, the device configuration can be reduced in size and weight, and moreover, the bounce of the newspaper P sent into the free space F can be reliably prevented, The same effect as that of the first embodiment can be achieved.

The present invention is not limited to the above embodiment, and can be variously modified in the implementation stage without departing from the scope of the invention. In addition, the embodiments may be implemented in combination as appropriate, in which case the combined effect is obtained. Furthermore, various inventions are included in the above-described embodiment, and various inventions can be extracted by a combination selected from a plurality of disclosed configuration requirements. For example, even if some configuration requirements are deleted from all the configuration requirements shown in the embodiment, the problem can be solved, and if an effect is obtained, a configuration from which this configuration requirement is removed can be extracted as the invention.
