Description

  The present invention relates to, for example, a sheet stacking and conveying apparatus that stacks sheets fed in a first direction and sends the sheets in a second direction.

  For example, an accumulation device for accumulating a collated bundle in which a plurality of folded and folded sheets are collated has a pressing member for pressing the collated bundle at the upper end in the stacking direction in order to stabilize the collated posture of collated bundle. This pressing member separates the collated bundle from the collated bundle so that the pressing force on the collated bundle is released because the colleted bundle is transferred from the collated bundle when the collated bundle is transferred to the lifter or the like. Be done.

At the leading end in the sheet feeding direction of the origami s, a locking portion 11 for locking the leading end of the origami s at a predetermined position is provided. The locking portion 11 stops the origami s at a position where the central position of the origami s in the sheet feeding direction faces the nip of the folding roller pair 9. A folding knife 12 is disposed diagonally above the folding roller pair 9 for pushing the central portion of the origami s toward the nip of the folding roller pair 9.

  That is, the folded and inserted documents t inserted through the respective sheet feeding trays 2 are overlapped by the conveying path 3 and fed to the nip of the pair of folding rollers 9. At this time, the center of the origami s fed in advance is folded in by the folding knife 12. Then, in the overlapped state, a plurality of folded and folded documents t conveyed via the conveyance path 3 are pushed into the center of the origami s, and are sandwiched between the origami s by the rotation of the folding roller pair 9. A bundle of folded leaflets passed through the folding roller pair 9 and folded in two, that is, a collated bundle T having a plurality of folded leaflets t sandwiched between origami s, is delivered to the transport belt 13 and discharged roller pair It is discharged from the discharge port 15 provided in the front of the housing 1 through 14.

  FIG. 3 is an external perspective view showing an example of a collated bundle T discharged from the discharge port 15 of the collating mechanism 10. 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 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 perspective view of the stacking and aligning mechanism 40. As shown in FIG. FIG. 6 is a schematic view showing an essential part of the accumulation and alignment mechanism 40 in a simplified manner. The accumulation and alignment mechanism 40 is an example of a paper sheet accumulation and transport device.
A stacking / alignment mechanism 40 is disposed on the downstream side of the direction of discharge (Y direction) of the paper sheet K (or the double bundle T) by the discharge conveyor 39. In the in-fill mode and the collating mode, the paper sheet K is discharged through the discharge conveyor 39, and in the collating mode, the collated bundle T is discharged through the discharge conveyor 39. Here, the case where the sheet K (sheets) is discharged through the discharge conveyor 39 will be described as an example.

  The discharge conveyor 39 is formed by winding and stretching an endless belt 39c around a pair of belt rollers 39b and 39b, and the upper surface 39a of the belt 39c is provided to run in the Y direction (first direction). ing. The newspaper P conveyed in the X direction by the newspaper conveyance / opening mechanism 30 falls on the upper surface 39 a of the discharge conveyor 39. While falling from the newspaper conveyance / opening mechanism 30 to the discharge conveyor 39, a collated bundle T is inserted between the upper portion P1 and the lower portion P2 of the newspaper P, 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.

  The stacking and aligning mechanism 40 is provided in front of the discharge conveyor 39 below the upper surface 39 a of the discharge conveyor 39. The stacking and aligning mechanism 40 has a stacking conveyor 41 (FIG. 5) which can move up and down. The accumulation conveyor 41 has a structure in which an endless conveying belt 44 is wound around a pair of belt rollers 42 and 43 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 accumulation conveyor 41 functions as a feeding member that causes the upper surface 44 a of the conveyance belt 44 to travel in the X direction (second direction) along a substantially horizontal surface.

  At the rear of the stacking conveyor 41, two rails 46, 46 are spaced apart in the X direction and extend in the vertical direction (Z direction). A frame 45 rotatably supporting both ends of the pair of belt rollers 42, 43 is mounted so as to be movable up and down along two rails 46, 46 extending in the vertical direction. That is, the accumulation conveyor 41 is disposed at a predetermined height position, places the assembly paper K discharged in the Y direction via the ejection conveyor 39 on the upper surface 44 a of the transport belt 44 and receives the assembly paper K Each time it accumulates it descends little by little.

  Two guide plates 47 and 47 (abutment members) and two guide rollers 48 and 48 (rolling members) are provided on the front side (downstream side in the Y direction) of the accumulation conveyor 41. The two guide plates 47, 47 are provided separately in the X direction along the front end edge of the transport belt 44 on the upper surface 44a side. The two guide rollers 48, 48 are respectively combined near the lower end of the guide plate 47 and provided in the X direction at a distance. The guide rollers 48 are attached in such a direction that they come in contact with the upper surface of the paper sheet K at the uppermost end in the stacking direction of the paper sheets K moving in the X direction as described later.

  The guide plate 47 strikes the Y-direction leading end of the sheet K which is carried out from the newspaper conveyance / opening mechanism 30 in the Y direction via the discharge conveyor 39 and falls onto the accumulation conveyor 41. The upper end of the guide plate 47 is inclined rearward so as to abut the front end of the paper sheet K in the Y direction, that is, the fold P-1 of the newspaper P and guide downward to the guide roller 48. That is, as shown in FIG. 6, the guide plate 47 is inclined rearward toward the upper surface 44 a of the accumulation conveyor 41.

  The guide roller 48 is provided below the guide plate 47 and inclined at substantially the same angle as the guide plate 47. In other words, the rotation axis of the guide roller 48 extends in a direction substantially orthogonal to the inclined surface of the guide plate 47. The guide roller 48 has a substantially disc-like outer shape, and the outer peripheral surface thereof is continuously curved toward both axial end surfaces. In other words, the radial cross section of the guide roller 48 is substantially oval. The guide plate 47 and the guide roller 48 are integrally attached to the slider 49 at a predetermined angle.

  Each slider 49 is vertically movably mounted along two rails 51 separated in the X direction on the downstream side of the stacking conveyor 41 in the Y direction and extending in the vertical direction. That is, the guide plate 47 and the guide roller 48 are mounted so as to be movable up and down along the rail 51 separately from the accumulation conveyor 41. A pulley 52 is provided at the upper end of the rail 51. A belt 53 is wound around the pulley 52. One end of the belt 53 is fixed to the slider 49. A weight 54 is attached to the other end of the belt 53.

  The weight 54 offsets a portion of the weight of the slider 49 having the guide plate 47 and the guide roller 48, and the uppermost end of the sheets of paper K accumulated on the upper surface 44 a of the transport belt 44 of the accumulation conveyor 41 The contact pressure of the guide roller 48 against the upper surface of K is adjusted to an appropriate value. That is, by changing the weight 54, the contact pressure of the guide roller 48 can be adjusted. Conversely, a weight can be provided on the slider 49 side.

  That is, the guide roller 48 is disposed at a position where a portion of the guide roller 48 comes in contact with the top surface of the topmost sheet K stacked on the accumulation conveyor 41 by the lowering of the slider 49. The guide plate 47 guides the leading end of the web K so as to press the front end of the next web K in the Y direction between the web K and the guide roller 48 already stacked on the stacking conveyor 41. Therefore, a part of the outer peripheral portion of the guide roller 48 protrudes below the lower end of the guide plate 47.

  The guide roller 48 contacts the web K with the contact pressure adjusted as described above, and as shown in FIG. 6, when the leading end of the next web K is pushed up, the web K rises by the thickness of the web K Do. In other words, the contact pressure of the guide roller 48 against the paper sheet K adjusts the Y-direction leading end of the newly accumulated paper sheet K to an appropriate value that can be pushed between the paper sheet K and the guide roller 48 already accumulated. It is done.

  The stacking and aligning mechanism 40 has an X-direction strike plate 55 and a Y-direction strike plate 56. The X-direction strike plate 55 is disposed at a position facing the end side of the upstream side (the left side when the apparatus is viewed from the front) of the combined paper K stacked on the stacking conveyor 41. The Y-direction strike plate 56 is disposed at a position facing the end side on the upstream side (rear side of the apparatus) of the paper sheets K stacked on the stacking conveyor 41 in the Y direction. The X-direction strike plate 55 vibrates in the X direction by an actuator (not shown), and the Y-direction strike plate 56 vibrates in the Y direction by an actuator (not shown). Thus, the edges of the paper sheets K stacked on the stacking conveyor 41 are aligned.

  When a certain number of sheets of paper K are stacked on the stacking conveyor 41, the transport belt 44 is moved in the X direction, and a plurality of stacked sheets of paper K are transferred to a lifter (not shown). At this time, the guide roller 48 in contact with the upper surface of the paper sheet K at the upper end in the stacking direction rotates in the X direction. That is, the guide roller 48 is provided so as to be freely rotatable in the X direction in a state where a part of the guide roller 48 is in contact with the uppermost paper sheet K.

  For this reason, in the present embodiment, when transferring a plurality of paper sheets K stacked by the stacking / alignment mechanism 40 to the lifter, the guide roller 48 is not retracted upward and remains as it is (the topmost paper sheet K The sheet of paper K can be moved in a state in which the guide roller 48 is in contact with the sheet. Therefore, according to the present embodiment, an actuator for retracting the guide roller 48 is not necessary, the apparatus configuration can be simplified, the manufacturing cost of the apparatus can be reduced, and the installation space of the apparatus can be reduced. can do.

  Further, according to the present embodiment, when transferring a plurality of paper sheets K stacked on the stacking conveyor 41 to the lifter, the guide roller 48 contacts the upper surface of the uppermost paper sheet K and rotates around the paper sheet K As a result, it is possible to suppress the problem that the sheet K collapses due to the friction by the guide roller 48, and the plurality of sheets K can be stably transferred to the lifter while being pressed in the stacking direction.

  Further, according to the present embodiment, as shown in FIG. 6, since the substantially disc-like guide roller 48 is inclined toward the stacking conveyor 41, one axial end face of the guide roller 48 (a pair of uppermost ends) The surface facing the paper K also functions as a guide surface for guiding the leading edge of the paper sheet K. Therefore, the guide roller 48 may be made relatively large in diameter and used instead of the guide plate 47. In this case, the guide plate 47 can be omitted, and the apparatus configuration can be further simplified.

FIG. 7 is a schematic view showing a modification of the stacking and aligning mechanism 40. As shown in FIG. Here, only the structure of the main part is illustrated, and the illustration and description of the components that function similarly to the configuration of FIG. 6 are omitted.
The apparatus of this modification is provided with a ball 61 (rolling member) for pressing from above the uppermost paper sheet K stacked on the stacking conveyor 41 instead of the guide roller 48. The spherical body 61 is rollably attached to the lower end of the slider 62 which can move up and down via the above-described support mechanism (not shown). A part of the sphere 61 projects downward from the lower end of the slider 62. The slider 62 holding the ball 61 rollably in this manner presses the surface of the ball 61 against the top surface of the uppermost sheet K of paper sheet by its own weight.

  As described above, when the ball 61 is used as the rolling member, the surface of the ball 61 can be functioned as a guide for guiding the leading end of the paper sheet K, and the guide plate 47 can be omitted. In addition, by using the sphere 61, when the leading end of the paper sheet K fed in the Y direction toward the accumulation conveyor 41 is pushed under the sphere 61, it can be moved to the paper sheet K, and from the sphere 61 to the paper sheet Undesired frictional forces acting on K can be reduced. Also, as a matter of course, when carrying out the accumulated paper sheet K in the X direction toward the lifter, the ball 61 is moved along with the paper sheet K, so an undesirable frictional force is applied to the paper sheet K Problems can be suppressed, and a plurality of sheets of paper K can be stably transferred to the lifter.

  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.

  In the embodiment described above, the case where the guide roller 48 and the ball 61 are pressed against the uppermost end of the sheet K by its own weight is described, but the invention is not limited thereto. May be moved up and down by an actuator.

  Further, in the embodiment described above, the roller and the spherical body have been described as an example of the rolling member. However, the invention is not limited thereto. Good.
