Description

[Detailed explanation of the idea] This invention relates to a winding core for cloth.

BACKGROUND OF THE INVENTION A measuring machine is used in retail stores to unwind curtain fabrics, clothing fabrics, and other fabrics wound into rolls or other shapes to the required length.

When rewinding the fabric with this measuring machine, the core is connected to the winding spindle of the measuring machine, the fabric is wound up to a predetermined length, and then the fabric is separated and the core is attached to the winding spindle. Then, the above-mentioned winding core is extracted from the roll-shaped fabric, and this winding core is again attached to the measuring machine.

However, since the conventional winding core has a cylindrical shape with a connecting shaft fixed to one end for connecting it to the winding spindle, it is very difficult to remove the fabric after winding it up, and it is difficult to remove it after winding up the fabric. There was a drawback that when the cloth was pulled out, six portions of the rolled cloth protruded and the shape was distorted.

This invention provides a fabric core that can be easily removed from a roll of fabric wound on its surface.

Examples of this invention will be described below with reference to the drawings.

The winding core body 1 is formed into a cylindrical shape having a slot 1a extending over the entire length by drawing a metal plate, and on both edges of the slot 1a, a groove protrudes inward at the center excluding both longitudinal ends. The projecting edges 1b and lb are formed in parallel.

The connecting shaft 2 fixed to one end of the winding core body 1 includes a fitting shaft portion 2a that is fitted into the winding core body 1, and a winding spindle (not shown) of the measuring machine, which is protruded from one end thereof. an engaging protrusion 2b that is removably connected to the auxiliary winding core 3; 2c, 2c, the above-mentioned fitting shaft portion 2a and receiving portions 2c, 2c are fitted into one end of the winding core body 1, and fixed by a knock pin 4 passing through the fitting shaft portion 2a.

The above-mentioned auxiliary winding core 3 can be slidably inserted into the slot 1a of the winding core body 1, and is made of a rectangular pipe with a rectangular cross section and a height lower than the diameter of the winding core body 1, and one end thereof is Connecting shaft 2
Receiving part 2C? 2C and are freely connected by a connecting pin 5, and a groove 3a cut at the other end is detachably attached by a ring 6 slidably fitted to the other end of the core body 1. The auxiliary winding core 3 is locked, and a part of the auxiliary winding core 3 is projected from the slot 1a in parallel with the winding core main body 1.

In the above structure, the groove 3a of the auxiliary winding core 3 is locked to the ring 6, and in this state, the connecting shaft 2 is connected to the winding spindle of the measuring machine, and the central part of the winding core body 1 and the auxiliary winding core 3 is Then, roll up the cloth A as shown by the chain line in FIG.

After winding up a predetermined length of the fabric A and removing the connecting shaft 2 from the winding spindle, when the ring 6 is pulled out from the core body 1, the pressure of the fabric A causes the auxiliary core 3 to press against the connecting pin 5.
Since most of the protruding portion of the auxiliary winding core 3 sinks inside the core body 1, the core body and the auxiliary winding core 3 can be easily pulled out from the rolled fabric A.

In the above embodiment, the protruding edge 1b is formed on the edge of the slot 1a of the core body 1, so that the core body 1 is reinforced and the auxiliary core 3 is smoothly fanned.

In the above embodiment, the core body 1 can be formed by drilling a slot 1a in the center of a cylinder instead of drawing a flat plate.

Further, the auxiliary winding core 3 can be formed of a pipe having a circular or oval cross section, or a solid rod such as a rectangular, circular, or oval cross section instead of a square pipe.

Further, the means for locking the other end of the auxiliary winding core 3 is not limited to the ring 6 of the embodiment. For example, a ring having a notch in a part may be rotatably attached, and the notch may be attached to the auxiliary winding core. 3
Alternatively, a foldable supporting leg may be attached to the bottom surface of the other end of the auxiliary winding core 3, or a support leg that can be freely folded may be attached to the bottom surface of the bottom end of the auxiliary winding core 3 and the bottom surface of the core body 1. A removable spacer may be inserted between the inner surface and the inner surface.

In addition, if the connecting shaft 2 is omitted and an engagement groove is cut at one end of the core body 1, and this engagement groove is engaged with the take-up spindle, the auxiliary core 3 can be directly connected.

It goes without saying that the present invention can also be used for winding machines other than those used after measurement.

As explained above, in this invention, one end of a rod-shaped auxiliary winding core that can be inserted into the slot is freely connected to one end of a cylindrical winding core body having a longitudinal slot, The other end of the auxiliary winding core is removably locked with a locking tool provided on the other end side of the core body, so that a part of the auxiliary winding core protrudes from the slot parallel to the core body, Since the other end of the auxiliary winding core sinks into the core body when the locking is released,
The other end of the auxiliary winding core is locked with a locking tool, and a part of the auxiliary winding core is protruded from the slot in the core body in parallel with the winding core body, and the end of the fabric is wound around the fabric of a predetermined length. When the fabric is cut after being wound up and the above-mentioned lock is released, the other end of the auxiliary core sinks inside the core body due to the tension of the fabric, and the compressive force on the core body of the fabric is loosened. , the winding core can be easily removed.
