Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention is a coil guide provided in a coiler for drawing a wire into a predetermined thickness, winding the wire around the coil, and sequentially pushing out the coil sideways. It is for converting downward, separating each roll one by one, and dropping it toward the carrier.

[0002]

2. Description of the Related Art A conventional example of this coil guide will be described with reference to FIG. 6A is a side view and FIG. 6B is a front view. From the horizontal drum D on which the coil C is formed,
Each turn of the coil C is extruded. A coil guide G including six bars B1 to B6 is attached to the drum D. The bars B1 and B6 are on the upper side and have a straight portion and a curved portion. The bars B2 and B5 are right next to each other and only have a straight portion. The bars B3 and B4 are on the lower side and have only straight portions.

The coil C extruded from the drum D is free and in a state of being scattered in the lateral direction.
Guided by the straight part of B6 and sent to the right side of the drawing.
Then, the coil C applied to the curved portions of the bars B1 and B6 located on the upper side suddenly rotates by its own weight and falls downward,
It is stacked in the state shown in FIG. 4 on a carrier (not shown).

That is, the coil guide shown in FIG. 6 is required to have a function of regularly dropping each turn of the coil while changing its posture from sideways to downward. When several rolls are collected and fall, the stacking state of the carrier is disturbed. It has been empirically known that the shape of the curved portions of the bars B1 and B6 is important in order for each turn of the coil to change its posture from sideways to downward. Therefore bar B1,
The curved portion of B6 was bent from the straight state of the chain double-dashed line so as to be optimal during actual operation.

[0005]

However, in the actual item setting, although the shape of the curved portions of the bars B1 and B6 is optimal for the wire rod operated at that time,
When the material changes, it is not optimal, and sometimes a few rolls may collect and fall. Such a phenomenon occurs not only when the material is changed, but also when the surface area reduction rate of the wire rod changes, each charge or due to the season. In the past, even if several turns were rolled and dropped, it was not a problem if it happened from time to time, but now that the demand for coil winding on a carrier arises as efficiently as possible, it cannot be ignored. However, the conventional coil guide has a problem in that its shape is fixed and cannot be easily changed after the actual matching, and it is not possible to easily adjust it in response to a change in conditions such as a material change.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a coiler capable of easily performing adjustment corresponding to a change in conditions such as a change in material. It is intended to provide a coil guide.

[0007]

The coil guide of the present invention which achieves the above object is provided in a coiler for laterally pushing out a coil formed by winding a wire rod, and changes the posture of the coil from lateral to downward to form a carrier. In order to guide, in a coil guide in a coiler in which a plurality of bars on which the coil inner surface slides are projected laterally from the coiler main body along the trajectory of the coil inner surface, at least the bars supporting the weight of the coil are swayed downward in a vertical plane. It is movably provided. If necessary, an auxiliary bar whose downward posture can be changed is attached to the tip of the bar.

[0008]

When the bar that supports the weight of the coil can be swung downward in the vertical plane, the resistance of the coil to slide down changes, and adjustments can be made in response to changing conditions such as when changing materials.
If an auxiliary bar whose downward attitude is variable is attached to the tip of the bar, fine adjustment for changing conditions and adjustment of the drop position for changing the carrier position can be performed.

The operation of the coil guide 36 will be described below. The coil C laterally extruded from the coiler 32 one turn at a time is slid on the coil guide 36, particularly on the bars 1 and 2, so that the coil C is converted to a downward posture and falls. When each turn of the coil C is dropped, an ideal stacked state is obtained as shown in the figure. If abnormalities such as unevenness occur in the fall of the coil C when changing the material or changing the area reduction ratio of the wire rod, the bars 1 and 2 are arranged in a vertical plane so that the coils 1 and 2 may fall smoothly. The coil guide 36 is swung in the vertical direction, and the postures of the bars 1 and 2 of the coil guide 36 are readjusted to an optimum state. Fine adjustment without swinging the bars 1 and 2 can also be performed by changing the downward posture of the auxiliary bar 20.

There are various heights of the carrier 35, and the low carrier 35 is lifted up to the position of the chain double-dashed line.
It will be lifted by a. In this case, the position of the carrier 35 is deviated from the solid line as shown by a chain double-dashed line. This carrier 3
In order to respond to the change of the drop position with respect to 5, the drop position of the coil C is adjusted using the entire auxiliary bar 20.

As described above, the falling state of the coil C can be arbitrarily adjusted as necessary by swinging the bars 1 and 2 and adjusting the downward posture of the auxiliary bar 20.
Therefore, it is possible to easily and quickly adjust the falling state of the coil C at the time of changing the material, changing the surface reduction rate of the wire rod, and the like, to maintain the optimum state.

[0023]

In the coil guide of the present invention, the bar for supporting the weight of the coil is provided so as to be swingable in the vertical plane, so that the bar is kept in the downward posture whenever the condition is changed such as when changing the material. It is possible to maintain the optimum condition by changing, and it is possible to prevent the winding state of the carriers from being disturbed by dropping several turns of the coil at one time. Further, if an auxiliary bar is attached to the tip of the bar, it is possible to cope with fine adjustment and change of the carrier position without changing the posture of the bar, and it becomes easier to carry out the adjustment for keeping the stacked state of the carriers optimal. Therefore, the coils can be stacked efficiently by effectively utilizing the height direction of the carrier.
