Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a suspension device for heavy-duty bobbinless coil wires.

[0002]

[Prior art]

 Conventionally, when attempting to lift or move a heavy bobbin in which a heavy coil wire is wound around an iron bobbin barrel, the two-claw hanger is inserted diagonally through the hole in the flange on the top of the bobbin. By lifting this with a crane or the like, the two-claw hanging metal fittings are parallel to each other inside the upper flange of the bobbin to support the heavy bobbin.

However, if the balance is lost during lifting, the heavy bobbin may fall, and it may be pinched when inserting the both-claw suspension fitting into the flange, which is very dangerous.

In recent years, a bobbin-less winding method has been adopted from the viewpoint of preventing vibration and noise generation as the coil wire winding is automated and speeded up.

[0005]

[Problems to be solved by the device]

 The present invention provides a heavy-duty bobbinless coil wire suspension device that does not cause flaws in the coil when lifting or moving a heavy bobbinless coil wire, is easy to handle, is highly efficient, and has high safety. The purpose is to

[0006]

[Means for Solving the Problems]

 The present invention has a lower metal fitting that is locked by coil wire binding bands at two or more opposite positions on the upper part of the coil, has a lower metal fitting having hooks on both sides, and a dovetail groove that fits the nail of the lower metal fitting, and has one end at one end. Horizontally connected to a horizontal connecting rod that has two fulcrums that are closer to each other than the space between the upper metal fitting with the stop plate and the lower metal fitting, and the upper metal fittings are suspended at both fulcrums via chains. A suspension device for a heavy bobbin-less coil wire, comprising a suspension hook connected to a rod.

[0007]

[Embodiment of device]

 Hereinafter, a method of using the suspension device for a heavy-weight bobbinless coil wire according to the present invention will be described. Lock a set of lower metal fittings on the upper surface of the heavy-duty bobbinless coil wire with the coil wire binding band at opposite positions. The lower metal fitting is provided with a claw, and while fitting the dowel groove of the upper metal fitting into this, the upper metal fitting is fitted into the lower metal fitting from the outer circumference of the coil. That is, a pair of lower metal fittings and upper metal fittings are arranged at positions facing each other on the upper surface of the coil.

A chain connection portion is provided on the upper fitting. The chain connection parts of the upper fittings arranged as described above are respectively connected to the fulcrums provided on two sides of the horizontal connecting rod by chains. Here, the distance between the fulcrums of the horizontal connecting rods is shorter than the distance between the chain connecting portions of the upper metal fittings arranged on the upper surface of the coil.

When the horizontal connecting rod is suspended by the suspension hook and the heavy bobbinless coil wire is suspended, tension is applied to the chain connecting the horizontal connecting rod and the upper fitting due to the weight of the coil. At this time, as described above, the distance between the fulcrums of the horizontal connecting rods is shorter than the distance between the chain connecting portions of the upper metal fittings arranged on the coil upper surface, so tension is applied to the chain inwardly of the coil.

Therefore, the pair of upper fittings are respectively pulled inward of the coil and hold the lower fittings tightly, so that the heavy-weight bobbinless coil wire can be safely suspended. Further, since the tension is lost when the coil is lowered, the tensile force received by the upper metal fitting is eliminated, and the upper metal fitting and the lower metal fitting can be easily attached and detached.

【Example】

 FIG. 1 is a side view showing a heavy bobbinless wire suspension device according to an embodiment of the present invention. This drawing shows a state in which the heavy bobbinless coil wire 5 is suspended by the suspension device according to the embodiment of the present invention. The suspension device of this embodiment comprises a ring 1, a first chain 2, 2 ', a second chain 3, 3', a horizontal connecting rod 4, upper fittings 10, 10 ', and lower fittings 15, 15'. It

One end of a first chain 2, 2 ′ is connected to the ring 1, and the other end of the first chain 2, 2 ′ is a first chain connecting portion 7, 7 ′ provided on a horizontal connecting rod 4. Connected to. The horizontal connecting rod 4 is provided with second chain upper connecting portions 8 and 8 ', which are connected to the second chains 3 and 3', respectively. The other ends of the second chains 3 and 3'are connected to the second chain lower connecting portions 11 and 11 'of the upper fittings 10 and 10', respectively. The upper metal fittings 10 and 10 'are fitted with the lower metal fittings 15 and 15' arranged at the positions facing each other on the upper surface of the heavy-weight bobbinless coil wire 5 to hold them tightly.

FIG. 2 is a sectional view showing a state in which the lower fitting 15 and the upper fitting 10 shown in FIG. 1 are fitted together. FIG. 3 is a side view of the same. The lower metal fitting 15 has claw portions 17 on both sides thereof and is locked to the coil upper surface by a coil wire binding band 14. The upper metal fitting 10 is provided with a second chain lower connecting portion 11 on the upper surface, and is fitted with the claw portion 17 of the lower metal fitting 15 by means of the dovetail groove 13 provided inside. A stop plate 12 is provided outside the coil of the upper fitting 10.

In the suspension device for a large-weight bobbinless coil wire having the above structure, when the coil is suspended as shown in FIG. 1, each chain receives tension due to the weight of the coil. Here, since the interval between the second chain upper connecting parts 8 and 8'is narrower than the interval between the second chain lower connecting parts 11 and 11 ', the tension in the coil inner direction is applied to the second chains 3 and 3'. It takes. Due to this tension, the upper fittings 10 and 10 'are pulled inside the coil, and the lower fittings 15 and 15' are held tightly. Therefore, the heavy-weight bobbinless coil wire can be reliably held and suspended.
