Description

Detailed Description of the Invention The present invention provides a storage container (
This method relates to a method for pulling out wire rods wound into coils and stored in a pack (hereinafter referred to as a pack), especially welding wire, etc., and in detail, it prevents winding up near the inner cylinder of the pack and draws out the wires stably. The purpose is to make it possible.

In general, the method of winding the wire into a coil inside the pack has good ability to follow sudden changes in the drawing speed (starting, stopping, etc. of drawing) when drawing out from the pack, and a simple drawing device can be used. It is widely used for winding and drawing out large-capacity wire rods because it can be sealed and has excellent rust prevention properties.

In addition, conventional methods for drawing out wire rods include attaching a collar of a certain width to the upper end of the inner cylinder of the pack, and passing the wire through a weight ball, but several turns of wire rod can be pulled out at the same time. There were drawbacks such as tangles within the pack due to the winding up, and pull-out failures such as tying the kick on the pack.

In order to solve these problems, the inventors of the present invention repeatedly conducted various experiments and studies, and as a result, they discovered the following about the causes of failure when pulling out the wire from inside the pack. Ta. In other words, the coiled wire inside the pack becomes slightly bent due to unavoidable vibration during transportation, and when the wire is pulled out in this state, the wire cannot be pulled out smoothly, resulting in the wire being unraveled as shown in Figure 1. Then, the wire was pulled out with the coil diameter reduced over several turns of the wire remaining at the bottom of the container, and as a result, the coiled wire with a smaller diameter wound around the inner cylinder, causing a winding problem. It is what happens.

In Fig. 1, 1 is the inner cylinder of the pack, 2 is the wire rod, arrow A indicates the direction in which the wire rod 2 moves, and arrow B is the inner cylinder of the pack.
indicates the winding direction.

Furthermore, as a result of further investigation into the cause of this pull-out failure, we found that the reduction in the coil diameter does not persist after that point, and that once the indentation is resolved, the coil will return to a normal coil shape as shown in Figure 2. We focused on the fact that there is a temporary transition to the unwinding state of the wire rod, and in cases where the wire rod is wound in a pack, which is in a so-called irregular winding state and is easily affected by vibration, it is better to prevent the wire from digging in. It has been found that it is more effective to establish a withdrawal method that allows some digging.

The present invention is a wire drawing method developed from this point of view, and will be described below with reference to FIG. 3 showing one embodiment of the present invention. FIG. 3 is a diagram for explaining the wire drawing method according to the present invention, and in the diagram, 10 is a back;
This bag 10 has a double cylindrical structure consisting of an inner tube 11 and an outer tube 12.

In the gap between the inner tube 11 and the outer tube 12 of the bag 10, a wire 13 is wound into a coil shape and stored. Furthermore, three guide wires 14 are stretched on the side surface of the inner cylinder 11 of the bag 10, extending from the bottom of the bag to the upper end surface of the wire 13 when the wire is fully loaded. 15 is a donut plate-shaped wire rod pressing jig, and this wire rod pressing jig is attached to the inner cylinder 1 of the bag 10.
The wire rod 13 is placed on the wire rod 13 housed between the wire rod 1 and the outer cylinder 12, and as the wire rod 13 decreases, it is lowered by its own weight.

The wire holding jig 15 also has three through holes 1 through which the guide wires 14 stretched on the inner tube 11 of the bag 10 pass through.
6 is provided. The purpose of the wire holding jig 15 is to hold down the winding of the wire 13 on the coil surface, and for this purpose, the outermost diameter must be at least 3 or more the set winding diameter of the wire 13, and the wire rod 13 must be lowered by its own weight. In order to perform this, a gap is required between the inner tube 11 and the outer tube 12 of the bag 10. Similarly, the through hole 16 on the wire holding jig 15 needs to be sufficiently large with respect to the diameter of the guide wire 14.
The guide wire 14 is passed through the through hole 16 on the wire holding jig 15 so that the wire 13 is wound through the gap between the inner cylinder 11 and the inner cylinder 11 provided for lowering the weight of the wire holding jig 15. In order to hold down the winding wire 13, if only one set of guide wire 14 and through hole 16 is used, the wire 13 on the other side is
Since the guide wire 14 and the guide wire 14 may wind up through the gap between the guide wire 14 and the guide wire 1 and lead to trouble, it is necessary to provide at least two sets of guide wires 14 and through holes 16 at opposing locations.

In addition, to take out the wire rod 13, use the wire rod holding jig 15 and the outer cylinder 1.
This will be done from the gap between 2 and 2.

As described above, according to the present invention, the wire can be drawn out stably without winding up from the coil surface, and since the wire holding jig descends under its own weight, there is no need for a complicated sliding mechanism between it and the bag. , it is possible to obtain excellent effects such as being simple and inexpensive to implement.
