Description

[Detailed description of the invention] (Field of industrial application) This invention involves winding up a long material such as a strip manufactured by a metal rolling machine, and then reducing the radius and removing the rolled material. Regarding the drum of the ceremony.

(Prior Art) Conventionally, as shown in the first diagram, a rotatable drum body a is provided with, for example, four radially movable segments b arranged in an annular shape. It is constructed such that a long material c such as a strip is wound around the outer periphery of the segment b by the rotation of the drum body a.

(Problem to be solved by the invention) In the one shown in the first diagram, the segment b is moved toward the center to form a void d between the coil of the long material c and the coil as shown in the second diagram. Then, hold the coil by lifting it from below and pull it out to the side.
A relatively narrow coil has the disadvantage that when it is lifted, it tends to lose its balance and fall over. It is also possible to use a sling e to lift the coil as shown in Figure 3, but since a void d is formed below the coil, it is difficult to insert the sling e.

SUMMARY OF THE INVENTION An object of the present invention is to provide a winding drum that can easily lift and remove a coil of a long wound object.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a rotatable drum body with a plurality of radially movable segments arranged in an annular manner. In a device for winding a strip or other long material, a fixed segment is provided between at least two segments, the fixed segment being fixed to the drum body and having an outer circumference approximately the same as each segment during winding. I did it like that.

(Function) Long materials such as strips are wound by moving the segments outward in the radial direction so that they have approximately the same diameter as the fixed segment, and when a certain amount of winding is completed, the segments are moved inward in the radial direction. let in this case,
The wound long coil is supported by two fixed segments, and a hole is formed between them, so a hanging jig is inserted there and the coil is lifted from the drum using a crane, etc. It can be easily removed by moving it sideways, and even narrow coils can be removed safely without falling over.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 4 to 7. Reference numeral 1 denotes a rotatable drum body, and numeral 2 denotes radially movable parts arranged annularly in the drum body 1. Segment 3 indicates a fixed segment fixed to the drum body 1 between two segments 2, 2, and each segment 2 is moved to a position with the same diameter as the fixed segment 3,
As the drum body 1 rotates, a long object 4 is wound around the outer periphery of each segment 2, 3. When winding of the long material 4 is completed, each segment 2 is moved radially inward as shown in Figure 5, and a jig is inserted into the space 5 formed between the fixed segments 3 to form a coil. Remove the long object 4 from the drum body 1.

Specifically, as shown in FIGS. 6 and 7, the drum body 1 has a rotating shaft 6 rotated by an electric motor or the like.
It consists of circular side plates 1a and 1b fixed with a key 7 and bolt 8, and 4
segments 2 are interposed so as to be movable in the radial direction. Each segment 2 is movable along a radial groove 10 that engages with a slide key 9 provided on the side plate 1a. 14, pins 15, 16 are attached to the core 12.
The segments 2 connected via the connecting rods 17 are moved in the radial direction all at once. The fixed segment 3 is a fan-shaped member fixed to the side plate 1a and is provided between the segments 2. 18 is core 12
When the anti-rotation pin is pulled out to the side through the side plate 1b and the shaft 19 of the gear 13 is turned with the handle, the segment 2 moves radially inward and the space between the fixed segments 3 and 3 is removed. A sky 5 is formed.

The long object 4 wound into a coil is hung by a crane or the like using a hanging jig 20 as shown in FIG. It is convenient because it can be easily removed from the drum body 1 and hung as shown in FIG. 9.

(Effect of the invention) As described above, in the present invention, since the fixed segment is interposed between the radially movable segments of the drum body, the segments can be moved radially inward to unwind from the drum body. A hole for removing a long object can be formed, and by inserting a jig through the hole, the long object can be removed easily and in a well-balanced manner, and its structure is relatively simple and inexpensive. It has the advantage of being easy to manufacture.
