Description

The present invention relates to a wire rod feeding device in which a winding material wound in a coil shape is guided by a pinch roller and fed downstream.

In general, as a metal material used for manufacturing various mechanical parts, a coiled winding material is often used in consideration of workability, convenience, transportation restrictions, and the like. For example, this winding material is attached to a wire rod feeding device so that the tip is set on a pinch roller, and then continuously fed downstream while passing through a group of straightening rollers, and a wire drawing machine or a wire rod winding machine is used. It is molded to a predetermined wire diameter and winding radius of curvature.

However, in order to set the tip of the winding material to be attached to the wire feeding device on the pinch roller, the operator hooks the tip with a crowbar or the like and moves it manually, and the larger the wire diameter of the winding material, the larger the wire diameter. , It tends to be difficult to attach the winding material.

On the other hand, Patent Document 1 describes a hanger roller (wire receiving roller) 102 that suspends and holds the winding material 101, and a gripping and pulling means 105 that grips and separates the tip 103 of the winding material 101 from the winding portion 104. A handling roller 106 that is arranged between the separated tip portion 103 and the winding portion 104 to maintain the separated state, and an induction pulling means 108 that contacts the separated tip portion 103 and pulls it into the pinch roller 107. The wire rod feeding device provided is disclosed (see FIG. 5).

The gripping and pulling means 105 is composed of a chuck member 109 that grips the tip 103 of the winding material 101 and a winch 111 that pulls in the wire 110 connected to the chuck member 109, and the tip 103 is separated from the winding portion 104. After the handling roller 106 is arranged between them, the tip portion 103 is opened by loosening the grip before being pulled into the pinch roller 107 by the induction pulling means 108 (see FIGS. 6 and 7).

JP-A-2005-34881 (Claims 1-4, paragraph 0018, FIGS. 1-3)

However, the wire rod feeding device of Patent Document 1 has a gripping and pulling means for grasping the tip portion of the winding material suspended and held and pulling it away from the winding portion, and maintaining a separated state between the tip portion and the winding portion. It requires a handling roller and an inductive pulling means for pulling the tip separated from the winding part into the pinch roller, which complicates the structure and pinches the tip of the winding material suspended and held. It takes three steps to pull it into.

An object of the present invention is to provide a wire rod feeding device capable of easily pulling a tip portion of a winding material suspended and held into a pinch roller with a simple configuration.

In order to achieve the above object, the wire rod feeding device according to the present invention is for guiding the winding material wound in a coil shape with a pinch roller and feeding it to the downstream side, and the winding material is externally fitted and suspended. It is provided with a long-axis hanger roller that is held down and a coil pulling means that pulls the tip of the winding material away from a portion adjacent to the coil center line direction and pulls it to the pinch roller, and the coil pulling means is centered on the coil. It is composed of a coil lead-in arm that can move in the linear direction and a coil lead-in bar that can be pulled in by engaging with the tip of the winding material, and the coil lead-in bar is detachable from the coil lead-in arm.

According to the above configuration, since the coil pull-in bar can be attached to and detached from the coil pull-in arm, a separate coil pull-in bar is inserted between the tip of the winding material and its adjacent portion and is engaged with the tip of the winding material. It can be attached to the coil retracting arm while being fitted. Here, the tip portion is a portion of the winding material that is relatively easily deformed, and the coil lead-in bar can be inserted between the tip portion and the adjacent portion thereof, for example, by hand.

After mounting the coil pull-in bar on the coil pull-in arm, the tip of the winding material can be moved to the pinch roller by moving the coil pull-in arm toward the coil center line, which is easy with the coil pull-in arm and the coil pull-in bar. With this configuration, the tip of the winding material that is suspended and held can be easily pulled into the pinch roller. That is, unlike the prior art, it is not necessary to pull the tip of the winding material apart by the gripping and pulling means, maintain the pulled state by the handling roller, and then pull the tip to the pinch roller by the induction pulling means.

Further, an induction roller for guiding the tip of the winding material to the pinch roller may be provided in the vicinity of the pinch roller.

According to this configuration, since the induction roller is provided in the vicinity of the pinch roller, the pinch is performed by simply moving the tip of the winding material to the vicinity of the pinch roller without accurately setting the position for pulling in the tip of the winding material. It can be guided to the roller.

As described above, according to the present invention, the winding material is suspended and held by a long-axis hanger roller, and the tip of the winding material is pulled away from the adjacent portion by a coil pulling means and pulled into the pinch roller. .. Further, the coil pulling means is composed of a coil pulling arm and a separate coil pulling bar, and the coil pulling bar is inserted between the tip of the winding material and its adjacent portion and mounted on the coil pulling arm, and then the coil is mounted. The pull-in arm is moved so that the tip of the winding material is moved to the pinch roller. As a result, the tip of the winding material suspended and held can be easily pulled into the pinch roller with a simple configuration using the coil pull-in arm and the coil pull-in bar.
