Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a core support in a fabric winding machine to which a fabric core is attached.

[Conventional technology]

As a means for winding a long cloth, an elongated flat plate-shaped winding core is assembled between a pair of rotating shafts that protrude opposite each other on an imaginary axis, and the cloth is wound by rotating this winding core. method is being adopted.

However, since the width and thickness of tanmono vary depending on the type, and the length also differs, the size of the core is not always constant. When winding up the fabric, it is necessary to do so quickly and with an appropriate winding force that does not damage the fabric.

Considering these points, it is difficult to wind all types of fabric in a desired form using a single fabric winding machine. That is, it has been impossible to freely assemble cores of different types and sizes between the pair of rotating shafts.

[Problem that the invention attempts to solve]

The present invention is a core support for a cloth winding machine devised to eliminate the above-mentioned conventional drawbacks and inconveniences. The purpose is to accurately and reliably achieve winding.

[Means for solving problems]

The core support 6 of the present invention is attached to the tips of a pair of rotating shafts 3 that protrude oppositely on the imaginary axis of the cloth winding machine 1, and A flat plate-shaped winding core B of the cloth A is attached between the winding core supports 6 located between the tips of the winding cores 3, and is composed of a support body 7, a pair of support pieces 12, and a holding piece 19.

First, the support body 7 has a flat plate shape, and its base end is attached to the tips of the pair of rotating shafts 3 of the cloth winding machine 1 described above, and the end surface of the winding core B mentioned above comes into contact with its elongated front end surface 8. .

Further, the pair of support pieces 12 are each fixed to both ends of one side 9 of the support body 7 described above in a posture protruding from the tip of the support body 7 and slidable in the width direction, with ends bent at approximately right angles. The bent portion 14 is located opposite to the side end surface 11 of the support body 7 .

The holding piece 19 is attached to the other side 10 of the support body 7.
It is attached to the center in a position protruding from the tip of the support body 7 and slidable in the thickness direction of the support body 7.

[Effect]

In the above-described configuration, the flat plate-shaped winding core B is
It is assembled into the support body 7 with its end face abutting against the elongated tip face 8 of the support body 7 .

That is, a pair of support pieces 12 at both ends of one side 9 of the support body 7 are slid in the width direction in advance in accordance with the width of the winding core B, and fixed respectively, and after the support body 7 is assembled, the support body 7 is further fixed. A holding piece 19 is attached to the center of the other surface 10 of the support body 7, and is fixed by sliding it in the thickness direction of the support body 7.

In this case, the support piece 12 and the holding piece 19 are each in a posture protruding from the tip of the support body 7, and the end surface of the winding core B is in contact with the tip surface 8 of the support body 7, and the end of one side is supported. Since it faces the piece 12, the side edge faces the bent part 14 of the support piece 12, and the center of the other face faces the holding piece 19, the end of the winding core B is held securely. .

In other words, by attaching and fixing the holding pieces 19, the ends of the core B are held by the bent portions 14 of the supporting pieces 12, and the ends of both sides are held by the supporting pieces 12 and the holding pieces 19. It will be clamped and held securely.

〔Example〕

The drawings illustrate one embodiment of the invention,
In FIG. 2, which shows a part of the cloth winding machine 1, a pair of columns 2 are erected on both sides of the upper part of a predetermined machine frame (not shown). On the surface, a pair of rotating shafts 3 are protruded to face each other on an imaginary axis, each of which is built into the support column 2 and runs at the same speed via a predetermined drive source (not shown). The endless chain 4 allows rotation in the same direction. A holder 5 is attached to each tip of the rotating shaft 3, and the base end of the support body 7 of the core support 6 is attached to the holder 5 by a predetermined means.

The support pieces 12 fixed to both ends of one side 9 of the support body 7 have bent portions 1 bent approximately at right angles to the side ends of the flat portion 13 facing the one side 9 of the support body 7.
4 is formed, and a horizontally elongated guide hole 15 and a fixing hole 16 are vertically opened in the plane portion 13 along the sliding direction, which is the axial direction.

Support pins 17 are provided at both ends of one side 9 of the support body 7.
is provided protrudingly, and by fitting into the guide hole 15, the support piece 12 is held slidably in the width direction, and by passing a fixing pin 18 through the fixing hole 16 and fixing it, the support piece 12 is supported. It can be fixed to the main body 7 at a predetermined position.

The sliding amount of the support piece 12 in the width direction is
is set according to the width of

The holding piece 19 has a flat plate shape and is attached to the support body 7 through a holding pin 21 at the center of the other side 10 of the support body 7, but apart from this holding pin 21, it is also attached by a guide pin 20. An elastic spring 22 that comes into elastic contact between the holding piece 19 and the support body 7 is wound around the guide pin 20 .

Therefore, the holding piece 19
With the holding pin 21 loosened, the winding core B is assembled to the tip of the supporting body 7 to which the pair of supporting pieces 12 are fixed, and then the holding pin 21 as elastic spring 2
Tighten it in the direction of the support body 7 against the elasticity of 2.
The holding piece 19 is fixed to the support body 7, and the holding piece 19
and the flat portion 13 of the pair of support pieces 12, the winding core B
In addition to holding the core B in the thickness direction, the bent portion 14 of the support piece 12 also holds the core B in the width direction.

Note that this elastic spring 22 may be a tension spring that acts in the opposite direction, or may be fixed only by the holding pin 21 without disposing the spring itself.

Now, the winding core support 6 having the above-described structure is assembled between the pair of rotating shafts 3 of the cloth winding machine 1 by the above-described means, and the winding core B is installed between the winding core supports 6 to form the endless chain 4. As it runs, it rotates, and the fabric A is wound around the core B.

In this case, the end of the cloth A is attached to the support body 7 in the holding piece 19 of the core support 6 and the pair of support pieces 12.
Since the part protruding from the tip of the holding piece 19 and the supporting piece 12 are thick, it will be difficult to wrap the holding piece 19 and the supporting piece 12.
It is also possible that the fabric A may be damaged by the corners.

Therefore, it would be better to cut out the corners of the supporting piece 12 or form a notch 23 at the tip of the holding piece 19 as shown in FIG.

〔effect〕

As is clear from the above explanation, the core support for the fabric winding machine of the present invention has a support piece of the support body that holds the core that slides and is fixed in the width direction in accordance with the width of the core. Since the holding piece of the main body is fixed in accordance with the wall thickness of the core, the end of the core is securely held and fixed, and winding can be achieved quickly and accurately without damaging the fabric. It has many excellent functions and effects, such as simple structure, easy manufacture and assembly.
