Abstract

A panel attachment structure for a wearable article manufacturing equipment includes: lower and upper panels vertically arranged while separated up-and-down; a first processing section and a first driving section respectively attached to a front face and a back face of the lower panel; a second processing section and a second driving section respectively attached to a front face and a back face of the upper panel; a base horizontally arranged under the lower panel; and a pair of pillars raised from the base, wherein, in the structure, the lower and upper panels are removably fixed to the pillars while being supported by the respective lower and upper parts of the pillars, and each pillar has a support section, provided between the upper and lower panels and supporting the load of the upper panel.

First claim

The invention claimed is:

1. A method of replacing a first unit, the first unit including a lower panel, a first processing section, and a first driving section,
the lower panel, the first processing section, and the first driving section constituting a part of a wearable article manufacturing equipment,
the manufacturing equipment including:
one set of the lower panel and an upper panel that are arranged along a vertical plane and that are provided while being separated in an up-and-down direction;
the first processing section attached to a front face of the lower panel;
the first driving section attached to a back face of the lower panel;
a base that is provided under the lower panel and that is arranged along a horizontal plane; and
a pair of pillars raised from the base,

wherein the lower panel is removably fixed to the pair of pillars in a state of being laid between lower parts of the pair of pillars,
the upper panel is removably fixed to the pair of pillars in a state of being laid between upper parts of the pair of pillars, and
support sections are provided on respective pillars of the pair of pillars, the support sections being arranged between the upper panel and the lower panel, and supporting the load of the upper panel,
the method of replacement comprises:
a step of removing the lower panel from the pair of pillars so as to remove the first unit from the pair of pillars; and
a step of replacing the first unit with a substitute first unit by attaching the substitute first unit to the pair of pillars, the substitute first unit being as a substitute for the first unit that has been removed from the pair of pillars,
wherein the removing step and the replacing step are performed in a state where the upper panel is fixed to the pair of pillars.

2. The method of replacement according to claim 1 , wherein:
the support sections are spacers each fixed to an intermediate part of each of the pair of pillars, the intermediate part positioned between each of the upper parts and each of the lower parts; and
the step of replacing is performed in a state where the spacers provide a space between the lower panel and the upper panel by contacting with respective parts of a lower end of the upper panel.

3. The method of replacement according to claim 2 , the first unit replaced by using a replacement unit,
the replacement unit including:
a carriage movable relative to the base;
a pair of guides that extends toward the lower panel in a horizontal direction in a state where the carriage is close to the base functioning as a platform; and
a slider that is able to slide over the carriage and the base along the pair of guides, the slider being able to be coupled with the lower panel, and the slider being movable from the base to the carriage after coupled with the lower panel, the method of replacement further comprising:
a step of moving the carriage close to the base that functions as the platform;
a coupling step of coupling the slider with the lower panel;
the step of removing being performed, subsequent to the coupling step; and
a step of transferring the first unit and the slider onto the carriage along the guide,
wherein the moving step, the coupling step, the removing step, the transferring step, and the replacing step are performed in a state where the upper panel is fixed to the pair of pillars.

4. The method of replacement according to claim 3 further comprising:
a step of coupling the slider with the substitute first unit via the substitute lower panel;
a step of moving the carriage close to the base as the platform so that the guide of the carriage bridges over the carriage and the base;
a step of transferring the substitute first unit together with the slider from the carriage onto the base along the guide; and
a step of fixing the substitute first unit to the pillar.

5. The method of replacement according to claim 2 , wherein:
the substitute first unit is prepared prior to all the steps;
the substitute first unit includes a substitute lower panel as a substitute for the lower panel; and
the substitute lower panel is attached with
i) a substitute first driving section as a substitute for the first driving section, and
ii) a substitute first processing section as a substitute for the first processing section.

6. The method of replacement according to claim 1 , the first unit replaced by using a replacement unit,
the replacement unit including:
a carriage movable relative to the base;
a pair of guides that extends toward the lower panel in a horizontal direction in a state where the carriage is close to the base functioning as a platform; and
a slider that is able to slide over the carriage and the base along the pair of guides, the slider being able to be coupled with the lower panel, and the slider being movable from the base to the carriage after coupled with the lower panel, the method of replacement further comprising:
a step of moving the carriage close to the base that functions as the platform;
a coupling step of coupling the slider with the lower panel;
the step of removing being performed, subsequent to the coupling step; and
a step of transferring the first unit and the slider onto the carriage along the guide,
wherein the moving step, the coupling step, the removing step, the transferring step, and the replacing step are performed in a state where the upper panel is fixed to the pair of pillars.

7. The method of replacement according to claim 6 , wherein the substitute first unit includes a substitute lower panel as a substitute for the lower panel,
the method further comprising:
a step of coupling the slider with the substitute first unit via the substitute lower panel;
a step of moving the carriage close to the base as the platform so that the guide of the carriage bridges over the carriage and the base;
a step of transferring the substitute first unit together with the slider from the carriage onto the base along the guide; and
a step of fixing the substitute first unit to the pillar.

8. The method of replacement according to claim 1 , wherein:
the substitute first unit is prepared prior to all the steps;
the substitute first unit includes a substitute lower panel as a substitute for the lower panel; and
the substitute lower panel is attached with
i) a substitute first driving section as a substitute for the first driving section, and
ii) a substitute first processing section as a substitute for the first processing section.
