Abstract

A cutting support apparatus includes an input unit that receives shoe last data, a storage in which a shape and a type of a plurality of plate-like parts are stored, a processor that generates a cutting pattern for cutting the plurality of plate-like parts from a plate-like member having a predetermined size based on the shoe last data and the shape of the plurality of plate-like parts, and an output unit that outputs the cutting pattern. The processor divides an area of the plate-like parts to be arranged in the plate-like member into a plurality of areas in accordance with the type of the plate-like parts that form the shoe last, determines positions of the plurality of plate-like parts to be arranged in each of the areas based on an arrangement condition, and generates the cutting pattern.

3 . The cutting support apparatus according to claim 2 , wherein
the memory is further configured to store an order of assembly of the plurality of plate parts, and the arrangement condition includes at least one of a condition of alignment of the plurality of plate parts in the order of assembly and a condition of minimization of an area of each of the plurality of cutting areas.

4 . The cutting support apparatus according to claim 3 , wherein
the order of assembly of the plurality of plate parts is performed in an order from a toe side of the shoe last.

5 . The cutting support apparatus according to claim 1 , wherein
the memory is further configured to store an order of assembly of the plurality of plate parts, and the arrangement condition includes at least one of a condition of alignment of the plurality of plate parts in the order of assembly and a condition of minimization of an area of each of the plurality of cutting areas.

6 . The cutting support apparatus according to claim 5 , wherein
the order of assembly of the plurality of plate parts is performed in an order from a toe side of the shoe last.

7 . The cutting support apparatus according to claim 5 , wherein
the arrangement condition further includes a condition of minimization of a time period for cutting the plurality of plate parts to be arranged in each of the plurality of cutting areas.

8 . The cutting support apparatus according to claim 7 , wherein
the arrangement condition further includes a condition that orientations of the plurality of plate parts to be arranged in each of the plurality of cutting areas are identical.

9 . The cutting support apparatus according to claim 5 , wherein

the processor is configured to provide the identification information to the cutting pattern such that orientations of the identification information are identical after the plurality of plate parts are assembled.

12 . The cutting support apparatus according to claim 1 , wherein
the processor is configured to generate the cutting pattern in which the plurality of plate parts are arranged as being distributed among a plurality of plate members.

13 . The cutting support apparatus according to claim 12 , wherein
when the cutting pattern requires a plurality of plate members, the processor is configured to generate the cutting pattern with a number of the plurality of plate parts to be arranged in the plurality of plate members being reduced from the plurality of plate parts.

14 . The cutting support apparatus according to claim 13 , wherein
the processor is configured to generate the cutting pattern, with a plate part among the plurality of plate parts being omitted based on a difference in size or shape from an adjacent plate part.

15 . The cutting support apparatus according to claim 1 , wherein the plurality of areas includes a toe part of the shoe last, an instep part of the shoe last, an ankle part of the shoe last, the malleolus part of the shoe last, a foot length part of the shoe last, a heel height part of the shoe last, and a circumferential heel part of the shoe last.

16 . A cutting system that generates a cutting pattern for cutting a plurality of plate parts that form a shoe last from a plate member and cuts the plurality of plate parts from the plate member based on the cutting pattern, the cutting system comprising:
a cutting support apparatus configured to generate the cutting pattern; and a cutting apparatus configured to cut the plurality of plate parts from the plate member based on the cutting pattern computed by the cutting support apparatus, wherein the cutting support apparatus includes:
