Disconnect.

In order to transport the divided elements by the divided element conveying unit, the cutting table includes a first table adsorption unit that adsorbs one of the divided elements in the divided elements adjacent to each other, and the first table adsorption unit. Is independent, and it is desirable to have a second table adsorption portion that adsorbs the other divided element.
With this configuration, it is possible to stop the adsorption of only the split elements transported by the split element transport section, and it is possible to reliably transport the split elements by the split element transport section.

As a specific embodiment for transporting the split element by the split element transport section, the cutting table is in a state where the connecting section is cut by the cutting mechanism and the split elements are separated from each other. The adsorption of the divided element by one of the 1-table adsorption unit or the second table adsorption unit is stopped, and the divided element transport unit conveys the divided element whose adsorption has been stopped in the cutting table from the cutting table.

With this configuration, the split element transport section can be configured by the transport mechanism or the carry-out mechanism, so that the device configuration can be simplified as compared with the case where the split element transport section is provided separately from the transport mechanism and the carry-out mechanism. Can be done.

As a specific embodiment for the transport mechanism or the carry-out mechanism to function as the split element transport section, the transport mechanism or the carry-out mechanism includes a first transport suction section that sucks the one set of split elements. It is independent of the first transport suction unit and has a second transport suction unit that sucks the other set of split elements, and the transport mechanism or the carry-out mechanism is the first transport suction unit. Alternatively, it is conceivable that the second transport suction section is used to function as the split element transport section.

Further, a method for manufacturing a cut product using the above-mentioned cutting device is also one aspect of the present invention.

In the present embodiment, the connecting portion W3 connecting both ends of the plurality of dividing elements W1 and W2 is cut. As a result, the plurality of dividing elements W1 and W2 of the object to be cut W are separated from each other. In this state, the cutting lines CL1 and CL2 between the odd-numbered row dividing element W1 and the even-numbered row dividing element W2 are staggered (staggered) and not on the same straight line, but on different straight lines.

(3) Transfer the even-numbered split elements W2 to another cutting table 11 In a state where the connecting portion W3 is cut and the split elements W1 and W2 adjacent to each other are separated from each other, the cutting table 2 is the second table suction portion 22.

In the cutting table 2, the adsorption of the odd-numbered row of the dividing elements W1 by the first table adsorption unit 21 is maintained. Here, before stopping the suction by the second table suction unit 22, the suction pad of the loader 4 serving as the split element transport unit 10 (specifically, the suction pad 412d of the second transport suction unit 412) is divided into an even number of rows. Press it against the element W2. This prevents the even-numbered rows of the dividing elements W2 from shifting due to stopping the suction of the second table suction portion 22 of the cutting table 2. Then, the second transport suction unit 412 of the loader 4, which is the split element transport unit 10, transports the even-numbered row of split elements W2 to another cutting table 11 (<even-numbered rows in another cutting table in FIGS. 7 and 8).

Further, the unloader 5 sucks and holds a plurality of cut products P sucked and held on another cutting table 11 by using the second suction transport unit 512, and transports the cut products to the cut product accommodating unit 7. Here, by pressing the suction pads 511d and 512d of the unloader 5 against the plurality of cut products P before releasing the suction of the cutting table 2 and another cutting table 11, the positions of the plurality of cut products P are displaced or the suction is erroneous. May be prevented.

<Effect of the first embodiment>
According to the cutting device 100 of the first embodiment, in a state where the dividing elements W1 and W2 are separated from each other, one of the dividing elements W1 and W2 adjacent to each other is transferred from the cutting table 2 to another cutting table 11. Since the portion 10 is provided, one of the dividing elements W1 and W2 adjacent to each other can be taken out from the cutting table 2 and held in the separate cutting tables 2 and 11. Thereby, the cutting object W in which the cutting lines CL1 and CL2 in the dividing elements W1 and W2 adjacent to each other are set on different straight lines can be easily cut by the blade 31.

(5) Carrying out the cut product P obtained by cutting the odd-numbered row of dividing elements W1 The unloader 5 sucks and holds a plurality of cut products P adsorbed and held on the cutting table 2 and conveys them to the cut product accommodating unit 7. .. Here, the suction pad 511d of the unloader 5 may be pressed against the plurality of cut products P before the suction of the cutting table 2 is released to prevent the positions of the plurality of cut products P from being displaced or the suction mistakes. ..

(6) Transport of even-numbered rows of split elements W2 The second transport suction unit 412 (split element transport section 10) of the loader 4, which is the split element transport section 10, sucks the even-numbered rows of split elements W2 on the temporary placement table 12. And hold it and transport it to the cutting table 2 (<Transfer even columns to the cutting table> in FIG. 10). The even-numbered rows of split elements W2 conveyed to the cutting table 2 are sucked and held by the second table suction portion 22 of the cutting table 2. Here, the positioning of the even-numbered column division element W2 with respect to the cutting table 2 may be performed by, for example, recognizing the arrangement of the even-numbered column division element W2 (for example, a feature portion such as an edge portion or a lead portion) with a camera. Conceivable.

(7) Cutting of the even-numbered split element W2 After the even-numbered split element W2 is conveyed to the cutting table 2, the cutting mechanism 3 transfers the even-numbered row of split elements W2 on the same straight line on the cutting table 2. The cutting line CL2 is cut (<cutting of even-numbered columns> in FIG. 10).

(8) Carrying out the cut product P obtained by cutting the even-numbered split elements W2 The unloader 5 sucks and holds a plurality of cut products P adsorbed and held on the cutting table 2 and conveys them to the cut product accommodating unit 7. .. Here, the suction pad 511d of the unloader 5 may be pressed against the plurality of cut products P before the suction of the cutting table 2 is released to prevent the positions of the plurality of cut products P from being displaced or the suction mistakes. ..

In the above, the even-numbered column split elements W2 are transported to the temporary placement table 12 by the split element transport section 10, but the odd-numbered column split elements W1 are transported to the temporary placement table 12 by the split element transport section 10. It may be configured to be used.
