Abstract

A delivery reel for an elongated sheet, having a disk-shaped flange member on which a sheet roll is positioned; an auxiliary core member of generally cylindrical shape split in the circumferential direction to enable expansion in diameter, and inserted into the inside diameter part of the sheet roll; a main core member fitted into the auxiliary core member which has been inserted into the sheet roll; and a stopper member attached to the circumferential edge of the flange member, and jutting toward the outside in the radial direction. The main core member has a plate spring. In a state in which the auxiliary core member has been inserted into the inside diameter part of the sheet roll, and the main core member has been fitted into the auxiliary core member, the plate spring presses the inside peripheral surface of the auxiliary core member toward the outside in the radial direction.

Claims21

Dependent claims

An elongated sheet feeding reel for stacking sheet rolls, each of which has been formed by winding an elongated sheet around a tubular support, one on another in a multi-tiered manner, and for continuously feeding the elongated sheets from the respective sheet rolls, the elongated sheet feeding reel comprising:

a core member configured to be fittingly inserted into the tubular support;
and
a flange member configured to be detachably attached to the core member,
wherein the flange member includes (i) a disk-shaped main body portion having an upper surface and a lower surface and (ii) a connection portion disposed on the lower surface of the main body portion and configured to connect the core member to the upper surface of the main body portion,
the core member is configured to connect to a connection portion disposed on a lower surface of a disk-shaped main body portion of a second flange member before a corresponding core member of the second flange member is connected to an upper surface of the main body portion of the second flange member, and
the core member includes at least one pressing member configured to press an inner peripheral surface of the tubular support radially outward by inserting into the tubular support.

An elongated sheet feeding reel for stacking sheet rolls, each of which is formed by winding an elongated sheet without using a tubular support and has an inner circular portion, one on another in a multi-tiered manner, and for continuously feeding the elongated sheets from the respective sheet rolls, the elongated sheet feeding reel comprising:

a circumferentially-expandable cylindrical secondary core member configured to be fittingly inserted into the inner circular portion;
a primary core member configured to be fittingly attached inside of the cylindrical secondary core member fittingly inserted into the inner circular portion;
a rotation stopping member for stopping rotation of the primary core member and the secondary core member relative to each other;
and
a flange member configured to be detachably attached to the primary core member,
wherein the flange member includes (i) a disk-shaped main body portion having an upper surface and a lower surface and (ii) a connection portion disposed on the lower surface of the main body portion and configured to connect the primary core member to the upper surface of the main body portion,
the primary core member is configured to connect to a connection portion disposed on a lower surface of a disk-shaped main body portion of a second flange member before a corresponding primary core member of the second flange member is connected to an upper surface of the main body portion of the second flange member,
the primary core member includes at least one pressing member configured to press radially outward an inner peripheral surface of the secondary core member by fittingly inserting into the secondary core member fittingly inserted in the inner circular portion.
