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 sequentially discharged to the accumulation and alignment mechanism 40 via the discharge conveyor 39 traveling in the Y direction and stacked. At this time, an X-direction strike plate 55 and a Y-direction strike plate 56 (described later) provided in the accumulation and alignment mechanism 40 are operated to align the end sides of the collated bundle T to be accumulated.
  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.
  When a processing command in the collating mode is input via the operation input panel (not shown), the newspaper feeder 20 takes out one copy each of the newspaper P, and the collating bundle is the same as in the collating mode described above. T is 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 and opening mechanism 30 by the newspaper supply mechanism 20, the newspaper P is transported in the X direction, and the upper portion P1 and the lower portion P2 of the newspaper P are opened. At this time, the collated bundle T sent in according to 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 and placed on the discharge conveyor 39 Be done.
  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 a predetermined number of sheets K are stacked, the predetermined number of sheets K stacked is 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 possible to reduce labor costs for work by the operator.
  FIG. 5 is a schematic view showing the newspaper feeder 20. As shown in FIG. Hereinafter, the newspaper supply mechanism 20 will be described with reference to FIGS. 1 and 5. The newspaper supply mechanism 20 is an example of the paper sheet pick-up device of the present invention.
  The newspaper supply mechanism 20 has an input unit 21 for inserting a plurality of newspapers P (sheets) in a standing position in the Y direction in a stacked state. The input unit 21 has a back wall 21 a at the rear in the Y direction and a bottom wall 21 b at the lower side in the Z direction. The rear wall 21a is slightly inclined so that the upper end side is inclined rearward from the lower end side. The bottom wall 21b is slightly inclined such that its rear end is inclined downward from its front end.
  Behind the input unit 21, two endless takeout belts 22a and 22b in contact with the rearmost newspaper P in the Y direction among the plurality of newspapers P are stretched. At the rear end of the input unit 21, there is a takeout position of the newspaper P. The two takeout belts 22a, 22b function as takeout members which travel downward along the takeout position.
  The takeout belts 22a and 22b have a part of the surface thereof slightly projecting inward (forward) from the rear wall 21a of the insertion portion 21, and are separated from each other in the X direction and extended substantially in the Z direction. In other words, the rear wall 21a of the insertion portion 21 is provided with a not-shown window portion extending in the substantially Z direction for exposing a part of the two takeout belts 22a and 22b to the inside of the insertion portion 21. .
  At the bottom of the input unit 21, two endless upstream feed belts 23a and 23b in contact with the lower ends of the plurality of newspapers P and two endless downstream feed belts 24a and 24b are stretched. It is set up. The upstream feed belts 23a and 23b function as a first feed member, and the downstream feed belts 24a and 24b function as a second feed member. The four feed belts 23a, 23b, 24a, 24b function as a feed mechanism.
  Each of the feed belts 23a, 23b, 24a, 24b has a part of its surface slightly projecting upward from the bottom wall 21b of the insertion portion 21 and is separated from each other in the X direction and extended in a generally Y direction. In other words, the bottom wall 21b of the loading section 21 has a not-shown window section extending in the substantially Y direction for exposing a part of the four feeding belts 23a, 23b, 24a, 24b to the inside of the loading section 21. It is provided.
  The length in the Y direction of the portion where the upstream feed belts 23a and 23b are exposed from the window portion of the bottom wall 21b is the length in the Y direction of the portion where the downstream feed belts 24a and 24b are exposed from the window portion of the bottom wall 21b. long. The rear end of the portion where the upstream feed belts 23a and 23b are exposed to the inside of the bottom wall 21b and the front end of the portion where the downstream feed belts 24a and 24b are exposed to the inside of the bottom wall 21b are in the X direction. Partially overlapping. Therefore, the newspaper P supported at its lower end by the upstream feed belts 23a and 23b is delivered to the downstream feed belts 24a and 24b and sent to the takeout position.
  The newspaper P contacts the feed belts 23a, 23b, 24a, 24b disposed at the bottom wall 21b of the input unit 21 with the fold P-1 shown in FIG. 4C, and the fold P-2 is viewed from the front of the apparatus It is inserted into the input section 21 in a standing position on the right side. As a result, the newspaper P at the rearmost take-out position in the stacking direction contacts the take-out belts 22a and 22b.
  The newspaper supply mechanism 20 takes out the rearmost newspaper P among the plurality of newspapers P inserted into the input unit 21 downward along the Z direction by traveling the extraction belts 22a and 22b. At this time, a pressing member 60 (FIG. 5) is provided on the opposite side (forward) to the take-out belts 22a and 22b along the stacking direction of the plurality of newspapers P to take out the plurality of newspapers P and between the belts 22a and 22b. The rearmost newspaper P may be taken out and pressed against the belts 22a and 22b by sandwiching them in the overlapping direction. Thereby, sufficient frictional force acts between the rearmost newspaper P and the takeout belts 22a and 22b, and the newspaper P transports the newspaper with the lower end in the Z direction (the end on the crease P-1 side) as the head. It is reliably fed into the opening mechanism 30.
  A plurality of newspapers P fed to the loading unit 21 are taken out one by one from the rearmost newspaper P one by one, and by two sets of feeding belts 23a, 23b, 24a, 24b provided at the bottom of the loading unit 21. It is moved backward sequentially. At this time, the feed speed of the downstream feed belts 24a and 24b is slightly faster than the feed speed of the newspaper P by the upstream feed belts 23a and 23b, and the lower ends of the plurality of overlapping newspapers P are separated from each other in the Y direction. It is made to supply to a taking-out position in the state where it was made to be.
  The newspaper P taken out of the input unit 21 is guided vertically downward with the fold P-1 at the top, and is fed to the newspaper transport and opening mechanism 30 through the feed roller pair 25. At this time, the newspaper P is curved and conveyed toward the front of the device through the conveyance guide 62 (FIG. 5) or the like disposed between the input unit 21 and the newspaper conveyance / opening mechanism 30 and the like, and is substantially horizontal. The attitude is converted into the attitude and sent to the newspaper transport and opening mechanism 30.
Hereinafter, the function of the newspaper supply mechanism 20 will be described in more detail with reference mainly to FIG.
As described above, the newspaper feeder 20 has the input unit 21 divided by the back wall 21a and the bottom wall 21b. As shown in FIG. 5, the back wall 21a is inclined such that the upper end is inclined rearward of the device from the lower end. The bottom wall 21b is inclined downward from the front to the rear of the apparatus.
  The takeout belts 22a and 22b provided on the back wall 21a extend along the slope of the back wall 21a with respect to the vertical plane. Further, the upstream side feed belts 23a and 23b and the downstream side feed belts 24a and 24b are also inclined and extended along the bottom wall 21b.
  For this reason, when a plurality of newspapers P are loaded into the loading section 21, the newspapers P arranged at the takeout position of one end in the stacking direction are inclined along the inclined back wall 21a, and the take-out belt 22a, It falls on 22b and is pushed. The pressing force of the newspaper P on the takeout belts 22a and 22b changes in accordance with the number of copies of the newspaper P to be piled and thrown into the insertion unit 21.
  In addition, when the number of copies of the newspaper P thrown into the insertion part 21 exceeds a fixed number, as shown in FIG. 5, a plurality of newspapers P are held between the take-out position and held on the front side of the device. The member 60 may be disposed, and the plurality of newspapers P may be taken out by the pressing member 60 and pressed against the belts 22a and 22b. In this case, for example, the pressing member 60 may slide by its own weight along the inclined bottom wall 21b.
  The downstream feed belts 24a and 24b provided along the bottom wall 21b near the removal position travel toward the removal position at a higher speed than the upstream feed belts 23a and 23b separated from the removal position to the front of the apparatus. Therefore, when the newspaper P sent to the take-out position with its lower end in contact with the upstream feed belts 23a and 23b is delivered to the downstream feed belts 24a and 24b, the lower ends of the overlapped newspapers P are separated Be done. That is, at least the lower ends of the newspapers P sent to the take-out position are separated in the overlapping direction.
  On the other hand, a spacer 64 (separating member) for separating the newspaper P from the take-out belts 22a and 22b is provided near the upper end of the newspaper P located above the back wall 21a, that is, at the take-out position. The spacer 64 may be, for example, three metal plates arranged in the X direction, which are arranged in a nested manner with two takeout belts 22a and 22b interposed therebetween. In this case, as shown, the spacer 64 fixes the proximal end to the back wall 21 a and causes the distal end to project toward the insertion portion 21 and is tilted. The inclination angle of the spacer 64 is, for example, an angle at which the tip end portion is inclined from the base end portion to the insertion portion 21 side. The spacer 64 is not limited to a plate shape, and may be any one as long as at least the upper end of the newspaper P at the takeout position is separated from the takeout belts 22a and 22b.
  Thus, by attaching the spacer 64 above the back wall 21a, at least the upper end of the newspaper P sent to the take-out position is separated from the take-out belts 22a and 22b, and is curved toward the insertion portion 21 as shown. Ru. That is, by providing the spacer 64, the upper end of the newspaper P is tilted to the front of the apparatus, the vicinity of the lower end of the newspaper P in the takeout position is partially pressed against the takeout belts 22a and 22b, and the lower end of the newspaper P is described later. Is directed to the nip of a pair of drawing rollers 68 (drawing and conveying mechanism).
  A cylindrical separating member 66 is provided adjacent to the rear end of the downstream feed belts 24a and 24b and below the bottom wall 21b. The separating member 66 is made of, for example, a rubber material, and abuts on the lower end of the newspaper P which is moved from the downstream side feeding belts 24a and 24b to the taking out belts 22a and 22b. The separating member 66 is extended in the X direction, and is movably provided in the direction of the arrow shown generally along the Y direction. The separating member 66 is urged toward the lower end of the takeout belts 22a and 22b (in the right direction in the drawing) to press the lower end of the newspaper P taken out from the takeout position against the takeout belts 22a and 22b.
  That is, the lower end of the newspaper P sent to the take-out position via the downstream feed belts 24a and 24b is separated by being in contact with the separating member 66, and the newspaper at the rearmost end of one end in the stacking direction The lower end of P is pressed against the takeout belts 22a and 22b. As a result, the lower end of the newspaper P at the takeout position can be taken out reliably and pressed against the belts 22a and 22b, and the newspaper P after the second set can be reliably separated.
  The separating member 66 is not limited to a cylindrical shape, but may be formed into any shape such as a triangular prism. Further, the material of the separating member 66 is not limited to rubber, and any material may be used as long as it can apply a suitable frictional force to the lower end of the newspaper P to apply a brake.
  On the downstream side of the take-out direction of the newspaper P taken out from the take-out position, that is, below the take-out position in the drawing, a draw roller pair 68 is provided for taking out the lower end of the newspaper P taken out from the take-out position. The drawing roller pair 68 receives the lower end of the newspaper P taken out from the take-out position into the nip and rotates at a speed higher than the take-up speed by the take-out belts 22a and 22b. Thereby, the newspaper P at one end in the stacking direction can be pulled out and separated from the other newspapers P.
  As described above, according to the newspaper supply mechanism 20 of the present embodiment, by using the downstream side feed belts 24a and 24b, the spacer 64, the separating member 66, and the drawing roller pair 68 in combination, the device configuration is relatively simple. A plurality of newspapers P can be reliably separated and taken out one by one in a short time.
  That is, in the present embodiment, since the traveling speeds of the downstream side feed belts 24a and 24b are made faster than the upstream side feed belts 23a and 23b provided at the bottom of the input unit 21, lower ends of the plurality of newspapers P sent to the takeout position Can be separated.
  Further, by separating the upper end of the newspaper P at the takeout position from the takeout belts 22a and 22b by the spacer 64, an appropriate contact pressure can be applied to the newspaper P at the takeoff position from the takeout belts 22a and 22b. The lower end of the newspaper P at the takeout position can be directed to the nip of the draw roller pair 68.
  In addition, since the separating member 66 is provided between the downstream side feeding belts 24a and 24b and the taking out belts 22a and 22b, the lower end of the newspaper P fed to the taking out position can be braked. And the lower end of the newspaper P closest to the take-out position can be reliably pressed near the lower end of the take-off belts 22a, 22b.
  Further, the lower end of the newspaper P taken out from the take-out position can be pulled out since the drawing roller pair 68 which rotates at a higher speed than the take-out belts 22a, 22b is provided downstream of the take-out position. The first newspaper P can be separated and transported.
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.
