In addition, on the cutting table 2, the first table suction part 21 maintains the suction of the divided elements W1 in odd-numbered rows. Here, before the suction by the second table suction part 22 is stopped, the suction pad of the loader 4 (specifically, the suction pad 412 d of the second transfer suction part 412 ) to be the divided element transfer part 10 is previously set. It is pressed against the division element W2 of the even-numbered row. Thereby, positional displacement of the division elements W2 of the even-numbered rows caused by stopping the suction of the second table suction part 22 of the cutting table 2 is prevented. Then, the second transfer suction unit 412 of the loader 4 serving as the divided element transfer unit 10 transfers the divided elements W2 of the even-numbered rows to the other cutting table 11 (<Conveying the even-numbered rows to the other cutting tables 11 in FIGS. 7 and 8 ). break the workbench>).

Moreover, the unloader 5 uses the 2nd conveyance adsorption|suction part 512 to adsorb|suck and hold|maintain the several cut products P which are adsorbed and hold|maintained by the other cutting table 11, and conveys this to the cut product storage part 7. Here, before the suction of the cutting table 2 and the other cutting tables 11 is released, the suction pad 511d and the suction pad 512d of the unloader 5 can be pressed against the plurality of cutting products P, so that the plurality of cutting products P can be prevented.

Extraction of even-numbered lines and cutting of odd-numbered lines>).

(5) Unloading of the cut product P formed by cutting the division elements W1 of odd-numbered rows The unloader 5 suctions and holds the plurality of cut products P suctioned and held by the cutting table 2 , and transports them to the cut product storage section 7 . Here, before the suction of the cutting table 2 is released, the suction pads 511d of the unloader 5 can be pressed against the plurality of cutting products P, so that the positional deviation or misalignment of the plurality of cutting products P can be prevented. adsorption.

(6) Transfer of the division element W2 of the even-numbered rows The second transfer suction unit 412 of the loader 4 serving as the divided element transfer unit 10 transfers the held divided elements W2 of the even-numbered rows to the cutting table 2 (<Conveying the even-numbered rows to the cutting table> in FIG. 12 ). ). The division elements W2 of the even-numbered rows conveyed to the cutting table 2 are sucked and held by the second table suction part 22 of the cutting table 2 . Here, the positioning of the even-numbered rows of the division elements W2 with respect to the cutting table 2 is performed by, for example, performing image recognition of the arrangement of the even-numbered rows of the division elements W2 (for example, feature parts such as edge portions and lead portions) by a camera, etc. .

(7) Cutting of the division element W2 of the even-numbered lines After the even-numbered rows of divided elements W2 are transferred to the cutting table 2, the cutting mechanism 3 cuts the cutting line CL2 of the even-numbered rows of divided elements W2 on the same straight line on the cutting table 2 (< in FIG. 12 . Even-numbered lines are cut off >).

(8) Unloading of the cut product P formed by cutting the division elements W2 of the even-numbered rows The unloader 5 suctions and holds the plurality of cut products P suctioned and held by the cutting table 2 , and transports them to the cut product storage section 7 . Here, before the suction of the cutting table 2 is released, the suction pads 511d of the unloader 5 can be pressed against the plurality of cutting products P, so that the positional deviation or misalignment of the plurality of cutting products P can be prevented. adsorption.

<Effects of the third embodiment> According to the cutting device 100 according to the third embodiment, since the dividing element W1 and the dividing element W2 are conveyed from the cutting table 2 in a state where the dividing element W1 and the dividing element W2 are separated from each other and hold one of the dividing element W1 and the dividing element W2 adjacent to each other, the The divided element conveying unit 10 can take out either of the divided elements W1 and W2 adjacent to each other from the cutting table 2 . Thereby, it is possible to easily cut the cutting object W in which the adjacent division elements W1, the cutting line CL1 in the division element W2, and the cutting line CL2 are set on different straight lines by the blade 31. .

<Other variant embodiments> In addition, this invention is not limited to each said embodiment.

For example, in the above-described first embodiment, the divided elements W2 of the even-numbered rows are transported to the other cutting table 11 , but the divided elements W1 of the odd-numbered rows may be transported by the divided element transport unit 10 . to other structures of the cutting table 11 .
