Description

[Detailed description of the invention] (Field of industrial application) The present invention is a method for forming bundles of wires wound in a ring, such as various electric wires and cables, with different inner diameters and thicknesses. The present invention relates to a striated body drum that can be held accordingly.

(Prior Art) There are various types of bundles of circularly wound filaments such as electric wires and cables, which have different inner diameters and thicknesses depending on the item and the number of turns.

Previously, Utility Model No. 48-50869, Utility Model No. 51-24549
As described in Japanese Unexamined Patent Publication No. 57-189217 and Japanese Unexamined Patent Publication No. 52-59884, a striated body drum having a structure in which the shaft diameter can be changed according to the inner diameter of a bundle of striated bodies is known. It is being

(Problem that the invention attempts to solve) However, Utility Model Publication No. 48-50869;
Although the linear body drum described in Publication No. 24549 can hold bundles of linear bodies according to various inner diameters of the bundle by changing the shaft diameter of the drum, the side frame is fixed. , the width of the drum cannot be changed and the thickness of the bundle of striatum cannot be accommodated. For this reason,
There has been a problem in that the striatum separates laterally, and this separation causes the striatum to twist, making it difficult to pull out the striatum properly.

The striated drum described in Utility Model Publication No. 57-189217 and Japanese Patent Application Publication No. 52-59884 has a structure that allows the width of the drum to be changed.
The device described in Publication No. 59884 has a structure in which changes in the width of the drum and changes in the shaft diameter of the drum are linked, so when the width of the drum is made smaller, the shaft diameter of the drum must be increased. Therefore, if the bundle of filaments has a small inner diameter and is not thick, the bundle cannot be held properly without the filaments falling apart laterally. Also, Utsukai Showa 57-189217
What is described in the issue is changing the width of the drum,
Although it has a structure that allows the drum shaft diameter to be changed separately, the side frame used to change the width of the drum is attached to the shell of the adjustment plate with push screws, and then attached to the drum shaft tube. Since the structure is such that the drum is fixed by a retaining ring, there is a problem in that when reducing the shaft diameter of the drum, the width of the drum cannot be made narrower.

The present invention was developed in view of these circumstances, and it is designed to combine bundles of wires and cables wound into rings with different inner diameters and thicknesses, and drums according to the inner diameters and thicknesses of the bundles. It is an object of the present invention to provide a linear body drum that can be held securely by changing the shaft diameter and width of the drum.

(Means for Solving the Problems) The linear drum according to the present invention has a central shaft 1 having a male thread on the outer periphery, and side frames arranged on both sides of the central shaft 1, one of which is fixed to the central shaft. The other side frame constitutes a movable frame 12 that is loosely fitted to the central axis, and the fixed frame has a movable frame that slides along the horizontal frame 15 of the fixed frame on the outer periphery of the central axis. A plurality of arc-shaped movable plates 3 having notches 4 open on the frame side are arranged, and each of the movable plates includes a female screw member that is screwed into the male screw of the central shaft, and a female screw member that has one end pivoted to the female screw member and the other end. The movable frame is made movable by an expanding means having a movable rod 8 which is slidably housed in the horizontal frame of the fixed frame and which moves the movable plate. The annular frame 14 is disposed inside the horizontal frame, and the movable frame includes a ring 22 having an inner diameter larger than that of the female screw member and inserted into the central shaft and interposed between the movable plate and the movable plate. A supporting means is provided which connects the ring and the annular frame of the movable frame and includes an elastic band 21 which is fitted into a notch in the movable plate.

(Function) In this linear drum, the expanding means moves the movable plate to change the shaft diameter of the drum. This makes it possible to accommodate various inner diameters of the bundle of filaments.

Furthermore, the width of the drum can be changed by moving the moving frame. In this case, the ring of the support means can be brought closer to the fixed frame by passing over the female threaded member of the expansion means, and the side surface of the bundle of filaments can be pressed down by the band. This makes it possible to accommodate various thicknesses of bundles of filaments.
