That is, the upper mold 21 </ b> A is lowered by the driving force of the folding mold driving unit 49, thereby forming a fold in the width direction W perpendicular to the transport direction F with respect to the paper P.

[Cutter mechanism 22]
The cutter mechanism 22 includes a pair of cutting blades 24 that extend in the width direction W and include an upper movable blade 24A and a lower fixed blade 24B that face each other. The upper movable blade 24A approaches and separates from the lower fixed blade 24B, thereby cutting the paper P at a predetermined position set along the width direction W orthogonal to the transport direction F. The upper movable blade 24A is connected to a cutting drive unit 50 such as a motor via a power transmission mechanism.

[Paper piece collection unit 23]
The paper piece collection unit 23 includes a paper piece storage box 65, a paper piece detection unit 68, and a guide member 64. FIG. 2 is a front view of the paper piece collection unit 23. FIG. 3 is a plan view of the paper piece collection unit 23. FIG. 4 is a perspective view of the paper piece collection unit 23. The paper piece storage box 65 is formed in a rectangular parallelepiped shape having an upper opening, and is cut by the cutting mechanism 18 to collect and store the paper piece J that is no longer needed.

The paper piece detection unit 68 includes a side paper piece detection unit 88 and an upper paper piece detection unit 89. The lateral paper piece detection unit 88 is configured by a reflective optical sensor including a light emitting element and a light receiving element. A plurality of the lateral paper piece detection units 88 are installed at intervals in the width direction W near the downstream side of the paper piece storage box 65 at a height position between the paper piece storage box 65 and the guide member 64.

The side paper piece detector 88 detects the presence or absence of the paper piece J in the upper part of the paper piece storage box 65 depending on whether the light from the light emitting element is reflected by the paper piece J and received by the light receiving element. The control unit 45 is preset with a predetermined time required for the paper piece J to move downward into the paper piece storage box 65 or a predetermined time slightly longer than this. When the light receiving element receives light from the light emitting element for a time longer than the set predetermined time, the control unit 45 determines that there is a paper piece J in the vicinity of the installation position of the side paper piece detecting unit 88.

The upper paper piece detection unit 89 is installed below the processing mechanism and above the paper piece storage box 65. The upper paper piece detection unit 89 detects the distance to the upper surface of the paper piece J accommodated in the paper piece storage box 65. The upper paper piece detection unit 89 is configured by a distance measuring sensor or the like, for example. In the control unit 45, two values for dividing the height of the paper piece J in the paper piece storage box 65 into three types of heights, a lower stage, a middle stage, and an upper stage, are set in advance. Then, the detection result of the upper paper piece detection unit 89 is compared with the two preset values, and the paper piece storage box is determined by determining whether the height of the paper piece J falls in the lower, middle or upper range. The amount of the paper piece J in 65 is determined.

The guide member 64 guides the paper piece J cut and cut by the cutting mechanism 18 to the paper piece storage box 65. The guide member 64 includes a side guide member 58, an upstream guide member 59, a downstream guide member 61, and a central guide member 62. The side guide member 58 is inclined and disposed above the paper piece storage box 65 so as to protrude outward in the width direction W from the side of the paper piece storage box 65. The side guide member 58 guides the paper piece J that is going to move downward from the side of the paper piece storage box 65 to the outside in the width direction W to the paper piece storage box 65.

As shown in FIG. 1, the upstream guide member 59, the central guide member 62, and the downstream guide member 61 are sequentially installed from the upstream side to the downstream side in the transport direction F of the transport unit 4. The most upstream upstream guide member 59 is installed below the margin drop member 55. The upstream guide member 59 is guided downward by the margin drop member 55 and guides the paper pieces Ja at both ends in the width direction W to move to the paper piece storage box 65.

The downstream guide member 61 is installed below the cutter mechanism 22. The downstream guide member 61 guides the cut paper piece Jc cut in the width direction W in the cutter mechanism 22 to the paper piece storage box 65. The central guide member 62 is installed between the upstream guide member 59 and the downstream guide member 61 and below the most downstream unit 20c among the three units 20a, 20b, and 20c constituting the slitter mechanism 20. . The central guide member 62 guides the paper piece Jb, which is cut in the unit 20c and becomes unnecessary in the width direction W, to the paper piece storage box 65.

The side guide member 58, the upstream side guide member 59, and the downstream side guide member 61 are all constituted by trapezoidal flat plates. The side guide member 58, the upstream side guide member 59, and the downstream side guide member 61 are connected like a funnel in a posture in which the trapezoidal flat plate is inclined at a predetermined angle with respect to the vertical direction, and integrated. It is installed above the paper piece storage box 65.

On the other hand, the central guide member 62 has a shape in which a rectangular flat plate is bent at a predetermined angle at the central portion 53. The central guide member 62 is installed in a roof shape above the paper piece storage box 65. That is, the center guide member 62 is installed such that the width direction W center portion 53 is the highest and the width direction W left and right edge portions 54 are lower than the center portion 53. As a result, the central guide member 62 includes a plurality of plane portions 57 having different inclination angles.

Further, the central guide member 62 is installed in a state where it is inclined at a predetermined angle with respect to the horizontal direction in the transport direction of the paper P. For this reason, the upper surface of the central guide member 62 forms an inclined portion 51 in which the distance from the conveyance surface of the paper P formed by the upper conveyance path 5 gradually changes. FIG. 2 shows a case where the central guide member 62 includes an inclined portion 51 whose distance from the conveyance surface gradually decreases as it goes downstream in the conveyance direction of the conveyance unit 4. In a vertical section parallel to the transport direction F of the paper P, the angle θ formed by the inclined portion 51 and the horizontal direction is preferably 60 ° or less, more preferably 45 ° or less, and 30 ° or less. More preferably it is.

The central guide member 62 includes a tilt guide part 70. The tilt guide part 70 guides the paper piece J moving downward toward the paper piece storage box 65 to tilt. The tilt guide section 70 tilts the paper piece J that has been moved in the standing posture, lays it sideways along the horizontal plane, lays it down, and puts it into a tilted posture. The tilt guide part 70 is configured by the upper surface of the guide member 64.

In the processing apparatus 100 shown in FIG. 1, the slitter mechanism 20 is installed on the upstream side of the cutter mechanism 22, and the cutting along the transport direction F of the paper P is performed before the cutting in the width direction W, so the upstream guide member 59. And the center guide member 62 often guides the piece of paper J that moves in an upright posture. That is, if the length of the paper P in the transport direction F is relatively long, the paper piece J cut along the transport direction F may be long. When the long paper piece J is guided and moved downward from the horizontal conveyance surface toward the paper piece storage box 65 by the margin dropping member 55 or the paper piece dropping mechanism 27, the paper piece J is likely to stand upright. . The upstream guide member 59 and the central guide member 62 guide the paper piece J moving in the standing posture in this way to the paper piece storage box 65.

[Processed product arrangement pattern of paper]
FIG. 5 is a plan view showing an example of an array pattern of the processed products Q of the paper P. FIG. The arrangement pattern of the processed products Q shown in the figure is such that four processed products Q having folds are produced from one sheet of paper P. Basically, four cutting lines S extending in parallel with the transport direction F, four folding lines C and eight cutting lines K extending in the width direction W are set. The folding line C and the cutting line K at the same position in the transport direction F are simultaneously formed by a single crease process and a cutting process. By cutting the paper P with these cutting lines S and K and forming a crease with the fold line C, four processed products Q having folds are produced. In the array pattern of the processed products shown in FIG. 4, since there are four cutting lines S parallel to the conveying direction F by the slitter mechanism 20, the center unit 20b or the most downstream unit 20c in the slitter mechanism 20 is provided. Only one of them is moved to a predetermined position in the width direction W for cutting, and the other is moved to the outside of the sheet conveying path 5 to be on standby.

[Overview of Overall Work of Processing Apparatus 100]
(1) From the operation panel 46 shown in FIG. 1, the user can measure the size of the paper P, the arrangement, number and size of the processed products Q, the size of the paper piece J cut from the paper P, the transport direction F, the width direction W, etc. Various work setting information relating to the length, number, etc. in a predetermined direction is input. Instead of this manual input or in cooperation with the manual input, the work setting information can be automatically input by reading the barcode M2 or the like by the reading unit 26.

(2) A plurality of sheets P stacked on the sheet feeding tray 3a of the sheet feeding unit 3 in FIG. 1 are supplied one by one from the upper end to the conveying path 5 by the suction conveying belt mechanism 8a and the sheet feeding roller 8.

(3) The reading unit 26 reads the position mark M1 of the paper P and, if necessary, the barcode M2 as necessary, and acquires various work setting information to be applied to the paper P.

(4) In the reject mechanism 25, if reading by the reading unit 26 is impossible and the processing conditions are unknown, the reject mechanism 25 operates on the paper P, drops the unreadable paper P and discards it. Collected in the tray 25a.

(5) In the slitter mechanism 20, the paper P is cut by a plurality of cutting lines S parallel to the transport direction F by the cutting blade 36. The left and right edge paper pieces Ja cut by the most upstream unit 20a are dropped to the lower paper piece collection section 23 by the margin dropping member 55, guided by the guide member 64, and received in the paper piece storage box 65.

(6) In the paper piece dropping mechanism 27, the paper piece Jb that has become unnecessary by being cut by the central unit 20b and the most downstream unit 20c in the slitter mechanism 20 is raised by the paper piece dropping member 28 toward the lower paper piece collecting unit 23. It is assumed to be a posture and guided downward. Then, the paper piece Jb in the standing posture is guided by the guide member 64 and stored in the paper piece storage box 65.

(7) In the crease mechanism 21, a crease is formed at the fold line C in the width direction W.

(8) In the cutter mechanism 22, the paper P is sequentially cut along the respective cutting lines K, and the paper pieces Jc that have become unnecessary after being cut from the paper P move downward, are guided by the guide member 64, and are collected by the paper piece collection unit 23. Is done. The processed product Q obtained by the cutting and crease processing is conveyed to the paper receiving unit 2 and stacked.

Thus, during the processing process of the paper P, the paper piece J that has become unnecessary after being cut by the slitter mechanism 20 and the cutter mechanism 22 is collected in the paper piece storage box 65. In particular, the paper piece J guided by the paper piece dropping mechanism 27 so as to move downward from the paper conveyance surface to the paper piece storage box 65 in an upright posture is tilted by the guide member 64 installed below, so that it is in a tilted posture. The direction is changed and is guided. In this way, the piece of paper J is in a tilted posture, laid sideways along a horizontal plane, and laid down. As a result, as indicated by the solid line in FIG. 6, the paper piece J is accommodated in the paper piece storage box 65 in an inclined posture, so that the bulkiness of the paper piece J in the paper piece storage box 65 can be eliminated. Therefore, as shown by a two-dot chain line in FIG. 6, the paper piece J is not stored in an upright position because the paper piece J is caught in the guide member 64 or the side wall 65 a inside the paper piece storage box 65. The bulkiness can be reduced by tilting and tilting sideways to the tilted posture.

Further, the paper piece J is guided by the flat surface portion 57 and moves in the width direction W while being inclined from the vicinity of the center of the paper piece storage box 65 to the side. Thus, as shown in FIG. 7, the paper pieces Jb cut out in the width direction W of the paper P are only stacked near the center in the width direction W of the paper piece storage box 65 and prevented from being stored. The piece of paper J can be accommodated near the side wall where the loading amount of J is relatively small.

Further, since the paper piece J is guided to a lower position as it goes upstream in the transport direction F by the inclined portion 51 and moves obliquely downward, the paper piece J is gradually guided downward while being placed in an inclined posture, and the leading edge of the paper piece J Can be guided to land at the corner of the paper piece storage box 65. Therefore, the paper pieces J can be efficiently stored and the amount of the paper pieces J stored in the paper piece storage box 65 can be increased.

And since the inclination guide part 70 is comprised by a plane, formation is easy and manufacturing cost can be reduced.

When the side paper piece detection unit 88 detects the paper piece J in the paper piece storage box 65 or when the upper paper piece detection unit 89 detects the paper piece J beyond a predetermined time, the control unit 45 detects the paper piece J. The processing of P is interrupted and an error message is displayed on the operation panel 46.

[Second Embodiment]
In the first embodiment, the center guide member 62 has a shape in which a rectangular flat plate is bent at a predetermined angle in the width direction W center portion 53. In the second embodiment, as shown in FIG. The central guide member 62a is formed in a semicircular shape in which a cylindrical member is divided in the axial direction. The curved surface of the cylinder is the upper surface, and is inclined at a predetermined angle with respect to the horizontal plane in the transport direction. The upper surface of the central guide member 62a constitutes a tilt guide part 70a. Therefore, the tilt guide part 70a is constituted by a curved surface. Further, the central guide member 62a is provided with an inclined portion 51a that is inclined at a predetermined angle with respect to the horizontal plane so that the distance from the conveyance surface gradually decreases as it goes downstream in the conveyance direction F of the conveyance unit 4.

In the second embodiment, the paper piece J cut out from the paper P and moved downward is tilted in contact with the tilt guide portion 70a formed of a curved surface and guided in the horizontal direction. At this time, when the thickness of the paper piece J is relatively thick or strong, the paper piece J has a curved surface rather than curved along the curved surface of the tilt guide portion 70a as shown in practice in FIG. Guided to the side while sliding.

Further, the inclined portion 51a made of a curved surface is guided obliquely downward so that the height of the paper piece J is gradually lowered. Thus, the paper piece J is easily changed in direction from the standing posture to the tilted posture, and is accommodated in a tilted state in the paper piece containing box 65 in a short time. Therefore, the paper piece J can be stored in the paper piece storage box 65 in a tilted state, the bulk of the paper piece J stored in the paper piece storage box 65 is eliminated, and more paper pieces can be stored.

[Third Embodiment]
In the first and second embodiments, the guide member 64 is installed in the paper piece collection unit 23. However, in the third embodiment, instead of this, the guide member 64b is provided in the paper piece dropping mechanism 27b. FIG. 9 is a schematic diagram of the paper piece dropping mechanism 27b and its periphery of the processing apparatus 100b of the third embodiment. In FIG. 9, the paper piece dropping member 28b includes a downward guide portion 29b and a tilt guide portion 70b.

The downward guide portion 29b is configured by an upper portion and a central portion of the paper piece dropping member 28b. The upper part of the paper piece dropping member 28b constitutes an inclined surface portion 39 having an inclined surface. The central portion of the paper piece dropping member 28b constitutes a vertically extending portion 40 that extends in the up and down direction continuously to the inclined surface portion 39. The downward guiding portion 29 b guides the paper piece J cut by the cutting blade 36 downward by the inclined surface portion 39 and the vertically extending portion 40. Thus, the paper piece J cut out from the paper P on the horizontal conveyance surface is guided downward, and the paper piece J is set in the standing posture.

The guide member 64b is configured by a lower portion of the paper piece dropping member 28b. The lower part of the paper piece dropping member 28b extends below the lower end part of the vertical extending part 40 and is installed in a state inclined at a predetermined angle with respect to the horizontal plane. The guide member 64b constitutes a tilt guide portion 70b that is guided by the downward guide portion 29b and guides the paper piece J that moves downward to tilt. Further, the guide member 64b includes an inclined portion 51b whose distance from the conveyance surface gradually decreases as it goes downstream in the conveyance direction F of the conveyance unit 4.

The piece of paper J guided by the downward guide unit 29 is tilted and changed in posture from the downward direction along the vertical direction by the tilt guide unit 70b. In addition, the paper piece J is guided obliquely downward by the inclined portion 51b and stored in the lower paper piece storage box 65.

Thus, in the processing apparatus 100b according to the third embodiment, since the tilt guide part 70b is provided in the paper piece dropping unit mechanism 27b and is configured by the lower part of the paper piece dropping member 28b, the number of parts can be reduced. Manufacturing cost can be reduced. Moreover, it can be installed in a small space. When the paper piece J guided by the tilt guide part 70b is long, the paper P is still being cut by the cutting blade 36, or is held by the transport roller 14 near the upstream side of the paper piece dropping part mechanism 27b. When it is in the state, the paper piece J can be tilted stably and reliably.

[Fourth Embodiment]
In the third embodiment, the tilt guide portion 70b provided in the paper piece dropping mechanism 27b is configured by a plane. In the fourth embodiment, instead of this, as shown in FIG. The part 70c is configured by a curved surface. The lower part of the paper piece dropping member 28c of the fourth embodiment is formed to be curved, and this curved portion constitutes the guide member 64c, further constitutes the tilt guide portion 70c, and constitutes the tilt portion 51c. As described above, the tilt guide portion 70c is formed of a curved surface, so that the paper piece J can be guided to tilt easily.

In the above-described embodiment, the guide member 64 guides the paper piece J that moves in an upright posture. However, instead of this, the guide member 64 may guide the paper piece that moves downward in a posture slightly inclined from the vertical direction. In addition, the inclined portions 51, 51 a, 51 b, 51 c gradually decrease in distance from the conveyance surface as they go downstream in the conveyance direction F of the conveyance unit 4, but are conveyed as they go downstream in the conveyance direction F of the conveyance unit 4 It is good also as a structure which the distance with a surface increases gradually. In this case, for example, by installing a central guide member below the most upstream unit 20a in the slitter mechanism 20, the paper piece can be tilted and guided toward the downstream side wall of the paper piece storage box.

Further, although the cutting blades 24 and 36 cut the paper P in the transport direction F and the width direction W, the paper may be cut along an oblique cutting line with respect to the transport direction F. In addition, since the slitter mechanism 20 is installed on the upstream side of the cutter mechanism 22, the sheet P is cut in the slitter mechanism 20 along the transport direction F of the transport unit 4, and then cut in the width direction W in the cutter mechanism 22. Although the rectangular paper pieces Ja and Jb of the scale and the rectangular paper pieces Jc shorter than the paper pieces Ja and Jb are generated, the shape of the paper pieces may be other shapes such as rhombus, square, triangle, polygon, etc. It is possible to make paper pieces of various sizes within a range that can be cut from the paper.

The various work setting information is manually set by the user from the operation panel 46 or automatically input by reading the barcode M2 by the reading unit 26, but communicates with an external information processing apparatus such as a personal computer. It may be set. Alternatively, a plurality of sheet arrangement patterns may be stored in advance in the storage unit by manual input from the operation panel, and each pattern may be called and set by a number or the like.

The processing apparatus 100 includes the slitter mechanism 20, the cutter mechanism 22, and the crease mechanism 21, but may be a processing apparatus including at least one of a slitter mechanism and a cutter mechanism. It is possible to apply the present invention to a processing apparatus in which a mechanism (including a perforation forming mechanism, a roundness forming mechanism, etc.) is appropriately combined, and further to a processing apparatus in which the number of processing mechanisms and transport roller pairs is different from that of the above embodiment Needless to say. Further, the arrangement pattern of the paper is not limited to the one illustrated in FIG. 4, and various other patterns can be set for the number of cutting lines S, K and broken lines C.
