Further, as shown in FIG. 8D, when the distribution mechanism 30 is composed of the main body 31 and the inclined portion 34, the upper surfaces 31a and 34a of the main body 31 and the inclined portion 34 are the first blank conveyance surface, the main body, and the like. The lower surfaces 31c and 34c of the part 31 and the inclined part 34 are the second blank conveyance surface, and the distributing part 33 is the end of the inclined part 34 on the side not connected to the main body 31. Further, as shown in FIGS. 8 (a), (b), (c), and (d), the main body 31 is preferably formed in a straight line, and as shown in FIGS. 32 is preferably formed to be curved inward.

  By the way, the blank carry-in portion 27A provided on the upstream side of the distribution mechanism 30 includes a plurality of conveyance rollers 27 and a first nip roller 21 sequentially provided from the upstream side, and includes between the conveyance rollers 27 and the first nip rollers. A pair of conveyor belts 25, 25 travels between 21, and the blank 1 is conveyed by the pair of conveyor belts 25, 25 and sent to the distribution mechanism 30 side.

  Further, as described above, the first blank discharge mechanism 22 </ b> A is installed on the downstream side in the horizontal direction of the distribution mechanism 30, and the first blank discharge mechanism 22 </ b> A has the second nip roller 22. Then, the transport belts 25 and 26 travel through the second nip roller 22, and the first blank 1 </ b> A is discharged to the blank transport unit 18 side by the transport belts 25 and 26.

  Further, the second blank discharge mechanism 24A is installed on the downstream side of the distribution mechanism 30 and obliquely below, as described above. The second blank discharge mechanism 24A includes the third nip roller 24 and the fourth nip roller 28. Yes. The conveying belt 25 runs on the rollers 24 and 28 on one side (opposite to the sorting mechanism 30) of the third nip roller 24 and the fourth nip roller 28, and the rollers on the other side (on the sorting mechanism 30 side). The additional conveyance belt 25a travels between 24 and 28, and the second blank 1B is discharged to the outside by the conveyance belt 25 and the additional conveyance belt 25a.

  Further, an intermediate roller 23 around which a conveyor belt 25 is stretched is disposed between the first nip roller 21 of the blank carry-in portion 27A and the second nip roller 22 of the first blank discharge mechanism 22A. The intermediate roller 23 is located immediately above the distribution mechanism 30, and the distribution mechanism 30 is disposed in a space 23 </ b> A between the first nip roller 21, the second nip roller 22, and the intermediate roller 23.

  The space 23 </ b> A has an upstream end defined by the first nip roller 21, a downstream end defined by the second nip roller 22, and an upper end defined by the intermediate roller 23.

  The distribution mechanism 30 is disposed in the space 23A and can freely rotate upward or downward in the space 23A. Thus, since the distribution mechanism 30 can rotate in the space 23A, the rotation range of the distribution mechanism 30 can be widened, and the second blank 1B is directed obliquely upward from the blank carry-in portion 27A. Even if the second blank 1B curled upward is conveyed, the second blank 1B can be reliably discharged. In addition, since the light blank 1 is easy to be conveyed diagonally upward from the blank carry-in part 27A, the blank sorting system of the present invention is, for example, the blank 1 composed of paper having a basis weight of 200 to 300 g / m 2. It is suitable with respect to the blank 1 comprised with 200-250 g / m <2> paper.

Note that the first nip roller 21 a distance W ₁ between the second nip roller 22 is preferably shorter than the length in the conveying direction of the blank 1. By configuring in this way, even if the blank 1 is horizontally long in the transport direction, the first blank 1A distributed by the distribution mechanism 30 can be reliably sent to the first blank discharge mechanism 22A side. The distance W ₁ indicates the distance from the center of the first nip roller 21 to the center of the second nip roller 22.

The first nip roller 21 a distance W ₂ between the third nip roller 24 is preferably shorter than the length in the conveying direction of the blank 1. By configuring in this way, even if the blank 1 is horizontally long in the transport direction, the second blank 1B distributed by the distribution mechanism 30 can be reliably sent to the second blank discharge mechanism 24 side. The distance W ₂ refers to the distance from the center of the first nip roller 21 to the center of the third nip roller 24.

  By the way, of the third nip roller 24 and the fourth nip roller 28, the rollers 24, 28 on one side (opposite to the sorting mechanism 30) are composed of rubber rollers, and the rollers 24 on the other side (on the sorting mechanism 30 side), Reference numeral 28 denotes a metal roller.

  The metal rollers 24 and 28 of the distribution mechanism 30 are always pressed by a pressing mechanism 29 having a spring 29a toward the rubber rollers 24 and 28 on the distribution mechanism 30 side.

  Next, the operation of the present embodiment having such a configuration will be described.

  First, as shown in FIG. 1, a printed sheet-like blank S including a first blank 1 </ b> A and a second blank 1 </ b> B having different shapes or designs is wound around a sheet feeding unit 12, and the sheet-like blank is transferred from the sheet feeding unit 12. S is unwound.

  Next, in the detection unit 13, the first blank 1 </ b> A and the second blank 1 </ b> B are discriminated from the sheet blank S unwound from the paper supply unit 12, and the sheet blank S is conveyed by the sheet conveyance unit 14.

  In this way, the detection unit 13 determines the first blank 1A and the second blank 1B from the sheet-like blank S that is unwound from the paper supply unit 12.

  Specifically, the detection unit 13 discriminates the first blank 1 </ b> A and the second blank 1 </ b> B having different shapes or designs from the blank 1 that is the product portion of the sheet-like blank S, and sends the detection result to the control unit 19. .

  Next, the sheet-like blank S conveyed by the sheet conveying unit 14 is sent to the punching unit 15. Then, in the punching part 15, the sheet-like blank S is punched and the sheet-like blank 5 is obtained.

  As shown in FIGS. 5A and 5B, the sheet-fed blank 5 has a plurality of, for example, 3 × 7 blanks 1 serving as product parts, and a blank portion 2 formed between the blanks 1. Further, each blank 1 and blank portion 2 are separated from each other at portions other than the plurality of connecting portions 3.

  Thereafter, the sheet-like blank 5 having the blank 1 and the blank portion 2 produced in the punching portion 15 is sent to the stripper portion 17. And in this stripper part 17, the connection part 3 is fractured | ruptured, each blank 1 is isolate | separated from the blank part 2, and the blank 1 arrange | positioned in 3 rows and 7 steps | rows in this way is obtained.

  By the way, since each blank 1 separated from the blank part 2 in the stripper unit 17 includes the first blank 1A and the second blank 1B, the first blank 1A and the second blank 1B are separated by the blank sorting system 10 according to the present invention. It is necessary to sort.

  In FIG. 1, the first blank 1A and the second blank 1B of each row among the three rows and the seven rows of blanks 1 are arranged in the same manner. Therefore, for convenience, the first blank 1A and the second blank 1B of one row are arranged. Show.

  Next, the operation of the blank sorting system 10 will be described.

  First, the blanks 1 arranged in 3 rows × 7 stages from the outlet 17 a of the stripper unit 17 are sent into the blank sorting system 10.

  In this case, a signal from the detection unit 13 is input to the control unit 19, and the control unit 19 distinguishes each blank 1 into a first blank 1A and a second blank 1B based on the signal from the detection unit 13 and specifies these. To do.

  Next, the control unit 19 rotates the sorting mechanism 30 of the blank sorting system 10 around the fulcrum 35. The distribution mechanism 30 includes a linear main body portion 31, a folded portion 32 that curves inward, and an inclined portion 34.

  That is, when the control unit 19 determines that the first blank 1A has entered the blank carry-in unit 27A of the blank sorting system 10 based on the signal from the detection unit 13, the control unit 19 does not rotate the sorting mechanism 30, or Rotate downward (see FIG. 3). At this time, the first blank 1 </ b> A that reaches the distribution mechanism 30 through the first nip roller 21 of the blank carry-in section 27 </ b> A is an inclined surface that forms the first blank conveyance surface by the distribution section 33 on the upstream side of the distribution mechanism 30. The upper surface 34 a of the main body 34 and the upper surface 31 a of the main body 31 are guided.

  Next, the first blank 1A is fed from the first blank conveyance surface of the distribution mechanism 30 to the second nip roller 22 side of the first blank discharge mechanism 22A. Next, the first blank 1 </ b> A is sent from the second nip roller 22 to the first blank stacking unit 18 and stacked.

However, when conveying the first blank 1A, the angle theta ₁ between the upper surface 31a and the horizontal direction of the main body 31, 0 ° to 10 ° downwardly with respect to the horizontal direction, preferably 2 ° to 7-° Located in range. When the main body portion 31 is directed upward with respect to the horizontal direction, the first blank 1 </ b> A may be caught by the distribution mechanism 30 without being appropriately transferred onto the first blank conveyance surface. Further, when the main body 31 is inclined downward by 10 ° or more, it takes a long time to rotate the sorting mechanism 30 and it is necessary to reduce the conveyance speed of the entire blank 1.

  On the other hand, when the control unit 19 determines that the second blank 1B has entered the blank carry-in unit 27A of the blank sorting system 10, the control unit 19 rotates the sorting mechanism 30 upward (see FIG. 4).

  At this time, the second blank 1 </ b> B that reaches the sorting mechanism 30 through the first nip roller 21 of the blank carry-in part 27 </ b> A is turned up by the sorting unit 33 on the upstream side of the sorting mechanism 30 to constitute the second blank conveyance surface. To the lower surface 32a.

  Next, the second blank 1B is fed from the second blank conveyance surface of the sorting mechanism 30 to the third nip roller 24 and the fourth nip roller 28 side of the second blank discharge mechanism 24A. Next, the second blank 1B passes through the third nip roller 24 and the fourth nip roller 28 and is stacked in the second blank stacking portion 40 located below the fourth nip roller 28.

When transporting the second blank 1B, the angle theta ₂ is 10 ° to 30 ° upwardly relative to the horizontal direction between the upper surface 31a and the horizontal direction of the main body portion 31, preferably located in the range of 10 ° to 25 ° To do.

  In this case, the second blank 1B curled upward moves to the upper surface 31a of the main body 31 and is not guided to the second blank discharge mechanism 24A when the main body 31 is at a position of less than 10 ° upward. Is also possible. Further, when the main body portion 31 is located at a position of 30 ° or more upward, a long time is required for the rotation time of the sorting mechanism 30, and the conveyance speed of the entire blank 1 needs to be slowed down. After transporting the second blank 1B to the second blank discharge mechanism 24A, the sorting mechanism 30 is preferably rotated to a position where the first blank 1A can be transported without rotating the sorting mechanism 30. By doing in this way, since the 1st blank 1A can be conveyed, without rotating the distribution mechanism 30, the production speed of 1st blank 1A can be raised. The position where the first blank 1A can be transported without rotating the sorting mechanism 30 is the side where the sorting mechanism 30 is in contact with the first blank 1A of the transport belt 26 in contact with the lower second two-up roller 22. Indicates a position below the surface 26a.

  As described above, according to the present embodiment, the first blank 1A is removed from the first blank transport surface of the distribution mechanism 30 by simply rotating the distribution mechanism 30 about the fulcrum 35. The second blank 1B can be guided from the second blank conveyance surface of the sorting mechanism 30 to the second blank discharge mechanism 24A side. As described above, the first blank 1A and the second blank 1B having different shapes or designs are easily and reliably sorted, the first blank 1A is accumulated in the first blank accumulating portion 18, and the second blank 1B is accumulated in the first blank 1B. It can be integrated into the two-blank stacking unit 40.

  Moreover, since the folding | returning part 32 of the distribution mechanism 30 has a shape which curves inward, it can guide smoothly to the 2nd blank discharge | emission mechanism 24A.

  Furthermore, since the main body 31 of the sorting mechanism 30 has an inclined portion 34 inclined downward toward the distributing portion 33 on the upstream side, the first blank 1A curled downward by the inclined portion 34. Even so, it can be more reliably guided to the first blank discharge mechanism 22A.

  In the modification shown in FIG. 9, the first blank 1 </ b> A and the second blank 1 </ b> B are sorted by the blank sorting system 10.

  In FIG. 9, the first blank 1 </ b> A is composed of a plurality of blanks including a third blank 1 </ b> C and a fourth blank 1 </ b> D having different shapes or designs, and the second blank 1 </ b> B is similar to the fifth blank 1 </ b> E having a different shape or designs. It consists of a plurality of blanks including 6 blanks 1F.

  For this reason, an additional blank sorting system 10A is provided on the discharge side of the first blank 1A of the blank sorting system 10, and an additional blank sorting system 10B is provided on the discharge side of the second blank 1B.

  The additional blank sorting system 10A, 10B has the same structure as the blank sorting system 10 described above, and the additional blank sorting system 10A uses the third blank 1C (faced (1)) in the first blank 1A, The fourth blank 1D (imposition (2)) is sorted. The third blank 1C and the fourth blank 1D sorted by the additional blank sorting system 10A are sent and accumulated in the third blank stacking unit 18a and the fourth blank stacking unit 40a, respectively.

  Similarly, the fifth blank 1E (faced (3)) and the sixth blank 1F (faced (4)) in the second blank 1B are sorted by the additional blank sorting system 10B. Then, the fifth blank 1E and the sixth blank 1F sorted by the additional blank sorting system 10B are sent and accumulated in the fifth blank stacking unit 18b and the sixth blank stacking unit 40b, respectively. As described above, FIG. 9 is an example in which an additional blank sorting system is provided on the discharge side of the blank sorting system 10. Although FIG. 9 shows an example in which an additional blank sorting system is provided on both the discharge side of the first blank 1A and the second blank discharge side 1B of the blank sorting system 10, an additional blank sorting system is provided on either one of them. You may do it.

  Next, a further modification of the present invention will be described with reference to FIG. FIG. 10 is an example in which a defective product blank sorting system 10 </ b> C is provided on the upstream side of the blank sorting system 10.

  In the modification shown in FIG. 10, the first blank 1 </ b> A includes “faced (1)”, and the second blank 1 </ b> B includes a blank “faced (2)”.

  The blank sorting system 10 sorts the first blank 1A including the blank “imposition (1)” and the second blank 1B including the blank “imposition (2)”. The second blank 1 </ b> B is accumulated in the second blank accumulation unit 40.

  In FIG. 10, a defective blank discharge system 10 </ b> C is provided on the downstream side of the stripper unit 17. The detection unit 13 detects the printing state, dirt, foreign matter, and the like, and the defective product blank recognized as a defective product by the control unit 19 is discharged outward by the defective product blank discharge system 10C. In this case, as the defective blank discharge system 10C, a system having the same structure as the blank sorting system 10 according to the present invention is used, a good blank is discharged instead of the first blank 1A, and a non-defective blank 1B is not used. A non-defective blank can be discharged. In addition, you may make it provide the detection part which detects a printing state, a stain | contamination, a foreign material, etc. separately from the detection part 13 which discriminate | determines that a shape or a pattern differs.
