Abstract

A manufacturing method for a carbon heat source comprises: a step A 1 of forming a first groove in a state where the plurality of carbon members are aligned in one line; a step A 2 of changing, subsequent to the step A 1 being performed, an orientation of the plurality of carbon members so that the first groove formed in the plurality of carbon members crosses relative to the first predetermined direction in a state where the plurality of carbon members are aligned in one line; and a step A 3 of forming, subsequent to the step A 2 being performed, a second groove in a state where the plurality of carbon members are aligned in one line.

First claim

The invention claimed is:

1. A manufacturing method for a heat source made of carbon, the method comprises the following steps:
providing a plurality of carbon members, each said carbon members having a pillar-like profile with an ignition end formed at a proximal end and a non-ignition end formed at a distal end;
a step A including:
step A 1 —conveying in a first predetermined direction along transport belts, the plurality of carbon members with the ignition end projecting upwardly wherein the plurality of carbon members are aligned in one line along the first predetermined direction,
forming a first groove in the ignition end of each of the plurality of carbon members, said first groove extending along the first predetermined direction in each of the plurality of carbon members and said first groove extending in a longitudinal axis direction from the ignition end towards the non-ignition end of each of the plurality of carbon members,
transporting the plurality of carbon members along the first predetermined direction;

step A 2 —changing, subsequent to the step A 1 being performed, an orientation of the plurality of carbon members by using transport belts so that the first groove formed in each of the plurality of carbon members is at a predetermined angle relative to the first predetermined direction in a state where each of the plurality of carbon members is aligned in one line while transporting the plurality of carbon members; and
step A 3 —forming, subsequent to the step A 2 being performed, a second groove crossing the first groove along a second predetermined direction in each of the plurality of carbon members, said second groove extending in the longitudinal axis direction from the ignition end towards the non-ignition end of each of the plurality of carbon members, wherein the plurality of carbon members are aligned in one line along the second predetermined direction while using transport belts for transporting the plurality of carbon members along the second predetermined direction.

2. The manufacturing method for the heat source made of carbon according to claim 1 , wherein the step A 2 is a step of turning each of the plurality of carbon members around a turning axis along the longitudinal axis direction while transporting the plurality of carbon members.

3. The manufacturing method for the heat source made of carbon according to claim 1 , further comprising a step B of chamfering an outer circumference of the ignition end of the plurality of carbon members.

4. The manufacturing method for the heat source made of carbon according to claim 3 , comprising the step B before the step A.

5. The manufacturing method for the heat source made of carbon according to claim 3 , comprising the step B after the step A.

6. The manufacturing method for the heat source made of carbon according to claim 3 , wherein the step B includes:
a step B 1 of turning each of the plurality of carbon members around a turning axis along the longitudinal axis direction while transporting the plurality of carbon members, in a state where the plurality of carbon members are aligned in one line along a predetermined direction; and
a step B 2 of chamfering the outer circumference of the ignition end of the plurality of carbon members in a state where each of the plurality of carbon members is turned around the turning axis.

7. The manufacturing method for the heat source made of carbon according to claim 4 , wherein the step B includes:
a step B 1 of turning each of the plurality of carbon members around a turning axis along the longitudinal axis direction while transporting the plurality of carbon members, in a state where the plurality of carbon members are aligned in one line along a predetermined direction; and
a step B 2 of chamfering the outer circumference of the ignition end of the plurality of carbon members in a state where each of the plurality of carbon members is turned around the turning axis.

8. The manufacturing method for heat source made of carbon according to claim 5 , wherein the step B includes:
a step B 1 of turning each of the plurality of carbon members around a turning axis along the longitudinal axis direction while transporting the plurality of carbon members, in a state where the plurality of carbon members are aligned in one line along a predetermined direction; and
a step B 2 of chamfering the outer circumference of the ignition end of the plurality of carbon members in a state where each of the plurality of carbon members is turned around the turning axis.
