(First Embodiment) A first embodiment of the present invention will be described below with reference to FIGS. The conveyed product merging and aligning device 10 includes a merging device section composed of a plurality of rows of conveyors 11 and merging conveyors 12, a curve conveyor 13, a delivery conveyor 14, and an alignment guide 16 provided on the curve conveyor 13. It consists of the alignment device part comprised by these.

  The carry-in conveyor 11 of the merge device section is a plurality of rows of parallel conveyors arranged at equal intervals in parallel with each other, and the merge conveyor 12 is connected in a direction intersecting the delivery end of the carry-in conveyor 11.

  In the curve conveyor 13 of the aligning unit, the feeding end of the curve conveyor 13 is connected to the sending end of the merging conveyor 12, and the sending end of the sending conveyor 14 is connected to the sending end of the curve conveyor 13. A post-process conveyor 15 is connected to the delivery end of the delivery conveyor 14 in the intersecting direction.

A U-shaped alignment guide 16 is disposed above the conveyance surface of the curve conveyor 13. The alignment guide 16 is preferably arranged at a position where the conveyed product W3 flows through the center of the conveyance surface of the curved conveyor 13 while being guided by the alignment guide 16.

  The carry-in conveyor 11, the merging conveyor 12, the curve conveyor 13, the delivery conveyor 14, and the post-process conveyor 15 are all belt conveyors and are operated by motors so that the speed of each conveyor can be arbitrarily set. It has become.

  The number of rows of the carry-in conveyor 11 is “n”, the number of all the conveyed items sent from all rows of the carry-in conveyor 11 is “X” (unit: piece / minute), and the carry-in conveyor 11 is installed at equal intervals. Is set to “Y” (unit: m), the speed (V12) of the merging conveyor 12 is set to V12 = XY / (n + 1) (unit: m / min).

  The speed (V11) of the carry-in conveyor 11 has a relationship of V11 ≧ V12 with respect to the speed (V12) of the merging conveyor 12. Further, the relationship between the speed of the delivery conveyor 14 (V14) and the speed of the post-process conveyor 15 (V15) is V14 ≧ V15.

  Based on the above conditions, for example, the speed of each conveyor in FIG. 1 is set as follows. The speed (V12) of the merging conveyor 12 is such that the number of rows (n) of the carry-in conveyor 11 is two, the total number of conveyed items (X) per minute sent out from the carry-in conveyor 11 is 70 pieces / minute, Since the installation interval is 0.6 (m), it is set to 14 m / min (= 70 × 0.6 ÷ (2 + 1)). The speed (V11) of the carry-in conveyor 11 is 60 m / min, the speed (V13) of the curve conveyor 13 is 30 m / min, the speed (V14) of the delivery conveyor 14 is 40 m / min, and the speed (V15) of the post-process conveyor 15 Is set to 8 m / min.

  Next, the operation will be described. As shown in FIG. 4, the conveyed products (A3 and B2) conveyed by the two rows of carry-in conveyors 11A and 11B are sent to the merging conveyor 12 almost simultaneously. At this time, the interval between the following conveyed items (the interval between A3 and A4, B2 and B3) is 2 / X, that is, 0.029 minutes (= 2 ÷ 70), and the following conveyed items (A4 and B3) are Since the joining conveyor 12 advances by 2 / 3Y, that is, 0.4 m in 0.029 minutes to be fed, the conveyed products A4 and B3 can be transferred on the joining conveyor 12 without interfering with each other. That is, if the speed (V12) of the merging conveyor 12 is set so that four articles (B2, A2, B3 schedule, A3) are accommodated during the installation interval Y of the carry-in conveyor 11, the carry-in conveyor 11A and the carry-in conveyor The transported goods transferred from 11 </ b> B do not interfere with each other on the merge conveyor 12. FIG. 5 is a diagram for explaining the operation when the carry-in conveyor has three rows. Also in this case, the speed of the merging conveyor 12 may be set to V12 = XY / (n + 1) (unit: m / min).

  Moreover, since the speed (V11) of the carry-in conveyor 11 is faster than the speed (V12) of the merge conveyor 12, the conveyed products A3 and B2 can be transferred to the merge conveyor 12 so as to be pushed out of the carry-in conveyor 11, and the merge conveyor when moving There is almost no change in direction when pulled in the direction of travel.

  As shown in FIG. 1, the conveyed product W <b> 2 transferred to the merging conveyor 12 is conveyed toward the curve conveyor 13. The conveyed product W3 transferred to the curve conveyor 13 abuts on the alignment guide 16, rotates 90 degrees in the traveling direction of the curve conveyor 13, and circulates on the curve conveyor 13 while being guided by the alignment guide 16. Then, it is sent to the post-process conveyor 15 via the delivery conveyor 14.

  Since the speed (V14) of the delivery conveyor 14 is faster than the speed (V15) of the post-process conveyor 15, the conveyed product W <b> 5 that transfers to the post-process conveyor 15 can be transferred to the post-process conveyor 15 so as to be pushed out. When moving, the direction of the post-process conveyor 15 is hardly changed by being pulled in the direction of travel.

  In this way, using the transported object merging and aligning device 10 according to the present embodiment, the transported objects flowing from the two lines can be merged into one line without interference, and the transported object (W1) in the carry-in conveyor 11 can be combined. Can be turned 90 degrees and aligned on the post-process conveyor 15 (W5).

  Further, since it can be manufactured by combining commercially available conveyors, it is low cost, and it is possible to remove the merging conveyor 52 of the conventional apparatus shown in FIG. 6 and replace it with the apparatus of the present invention. No major remodeling work is required.
