Description

[Detailed description of the invention] This invention is a winding machine that is used by being attached to a winch drum attached to the winch shaft of an automobile, and has a winding drum and left and right side frames located on each side of the winding drum. related to things.

Conventional winding machines of this type include those with a flat outer peripheral surface and those with a tapered outer peripheral surface.
A winding machine with a flat outer circumferential surface of the winding drum makes it difficult to remove the wire after winding from the winding drum, and a winding machine with a tapered outer circumferential surface of the winding drum results in random winding, which causes the wire to become curly. Got it.

This idea was made in order to eliminate the drawbacks of the conventional winding machine mentioned above.It flattens the outer peripheral surface of the winding drum during winding, and reduces the diameter of the winding drum when removing the wire after winding. It is an object of the present invention to provide a winding machine that can easily perform aligned winding and removal.

An embodiment of this invention will be described below with reference to FIGS. 1 to 6. In the figure, 1 is the winding drum, and the inner drum 1
It has an inner and outer double shell structure with an outer shell 1B and an outer shell 1B. The inner shell 1A includes three stop shell members 1a, three supporting shell members 1b arranged between them, and each of these shell members 1.
It is configured in a cylindrical shape by two annular plates 1c and 1d which assemble parts a and 1b. The stop barrel material 1a
The outer circumferential surface of the supporting body member 1b is an inclined surface 1e from the middle to the annular plate 1c, and the outer circumferential surface of the supporting body member 1b is also an inclined surface 1f from the middle to the annular plate 1c. The outer circumferential surface of the support body member 1b has a slightly raised chevron-like shape at the center of the width over the entire length. In this way, the inclined surface 1e of the stop barrel material 1a
and the inclined surface 1f of the support body member 1b form a tapered portion on the outer circumferential surface of the inner body 1A. The outer body 1B has three arcuate body plates 1 divided into three equal parts in the circumferential direction.
g and three reinforcing members 1h attached to the inner surface of the body plate 1g. Said reinforcing member 1
The inner peripheral surface of h is a sloped surface 1 with a thin taper on one side.
i, one-third of the other side is a sloped surface 1j with a thick tip. The three arc-shaped body plates 1g are slightly separated when they are at the maximum body diameter position as shown in Figures 1 and 3, and are slightly deformed when they are at the minimum body diameter position as shown in Figure 6. Its size and shape are determined so that it can be pulled. Reference numeral 2 denotes a protrusion protruding from the inclined surface 1i of the reinforcing member 1h at the central position, which is inserted into the elongated hole 3 of the inclined surface 1e of the retaining body member 1a, and its tip is fixed with a pin 5 via a washer 4. has been done. Reference numeral 6 denotes a T-shaped protrusion provided on the flat side end of the retaining body member 1a, which is fitted into the elongated hole 7 of the inclined surface 1j of the reinforcing member 1h at the central position. Reference numeral 8 denotes a mounting plate provided in the inner shell 1A, which is positioned by a lock pin 10 and attached to a winch drum 9 by a bolt 11, which is attached to a winch shaft (not shown) of an automobile. 12 is a side frame attached to the annular plate 1c, 13 is a side frame having an annular stop plate 13a in the center, and 14 is a side frame that connects the side frame 13 to the inner body 1A.
This is a stop handle for attaching to the outer end surface of the annular plate 1d, and is screwed onto the annular plate 1d. Reference numeral 15 denotes a presser foot provided on the annular stop plate 13a.

Now, when the wire is installed on the winch drum 9 as shown in FIGS. 1 to 4, it is rotated via the winch drum 9 by the driving force of the winch shaft of the automobile, so that the electric wire is wound onto the winding drum 1. It will be done.
When the winding is finished and stopped, each stop handle 14 is loosened, each presser foot 15 is removed, and the side frame 13 is removed from the winding drum 1 as shown in FIG. Then, the three body plates 1g are the inclined surfaces 1e,
1f is slid to the position shown in FIG. 5, and the diameter of the outer shell 1B is reduced as shown in FIG. 6, so that the wire that has been wound can be easily removed from the winding drum 1. Then, when the winding drum 1 becomes empty, the side frame 13
are inserted into each stop handle 14 and attached to the winding drum 1 by each stop handle 14 screwed from above each presser foot 15, and the three body plates 1g are attached to each body material 1.
It ascends the inclined surfaces 1e and 1f of a and 1b to reach the position shown in FIG. 3, and the diameter of the outer shell 1B becomes the maximum in the use state.

As described above, this invention makes it easier to wind wires in an aligned manner by flattening the outer circumferential surface of the winding drum during winding, and reduces the diameter of the winding drum to facilitate removal when removing the wire after winding. It is something to tighten. Therefore, the winding on the winding drum does not become uneven and the wires become curly, and it is not difficult to remove the wire after winding from the winding drum, resulting in poor workability. It's big.
