Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for supplying wire to a heading machine such as a header or a former.

When supplying wire rods to heading machines such as headers and homers, conventionally the wire rods are wound into coils and placed one turn at a time on a supply stand, and then fed into fixed lengths by a feeding device such as a feed roller. When one winding of wire is used up, a new winding of wire is loaded onto the supply stand, and the starting end of the winding is pushed into the feeding device to restart operation. The speed at which wire is consumed has increased significantly as speeds have increased, but the length of one turn of wire cannot exceed a certain level due to manufacturing and transportation reasons, so one turn of wire has become shorter. This was time-consuming and required frequent loading of new wire onto the supply stand, which hindered the realization of long-term unmanned continuous operation.

An object of the present invention is to enable continuous operation of a heading machine for a long period of time by sequentially connecting and supplying the starting and ending ends of two or more turns of wire.

An embodiment of the method of the present invention will be described below with reference to the accompanying drawings.

A material feeding device 2 consisting of a plurality of feeding rollers is installed on the rear surface of a heading machine 1 such as a header or a homer, and a wire feeding device 3 is installed behind it.

In this wire rod supply device 3, a hanging rod 6 is inserted between side plates 5, 5 which are erected in correspondence with each other on both sides of a substrate 4, and is inserted into and taken out from the substrate 4, and is freely rotatable. Winding wire A
I, A2. A3 is hung, and the winding start end of the first wire rod A1 is pinched by the rollers of the material feeding device 2 and fed into the heading machine 1, and the winding end of the first wire rod A1 and the winding start end of the second wire rod A2 and the second wire rod A2 are connected to each other. The winding end of the third wire A2 and the winding start end of the third wire A3 are connected by connectors 9, and the three turns of the wire A1, A2, jA3 are connected in series.

The connection structure of the wire rods by the connector 9 will be explained with reference to FIG. 2. The winding end of the first or second wire material AI, A2 is diameter-reduced to form a left-handed male thread 7, and the second or third wire rod Wire rod A2. The winding start end of A3 is diameter-reduced to form a right-handed male thread 8 and are butted against each other, and a left-handed female thread 12 is formed at one end and a right-handed female thread 11 is formed at the other end. Internal threads 11 on both sides of a cylindrical connector 9 with knurling 13 on the outer periphery of approximately the same diameter,
12 is screwed onto the male threads 7 and 8 at the ends of each wire A to connect them.

In this way, by connecting the winding end and the winding start end of two or more turns of the wire rod A, when the first wire rod A1 is used up, the second wire rod A2 is automatically transferred to the heading machine 1. It is pumped in to maintain continuous operation.

Note that if the connector 9 is used as a raw material, a defective product will be forged, but the passage of the connector 9 is detected by a limit switch, etc., and the If this part is cut off using a cutting device, there will be no problem.

As specifically explained in the above embodiments, the method for continuously feeding wire rods in a heading machine according to the present invention involves cutting wire rods into a certain length, loading the material into a die, and pressing the material with a punch to perform heading forming. In this method of supplying wire to a heading machine, the starting and ending ends of a single turn of wire wound into a coil are warped, and a right-handed male thread is attached to one end, and a left-handed male thread is attached to the other end. forming male threads respectively, abutting the winding end end of one turn of the wire rod against the winding start end of another turn of the wire rod, and forming female screws with left and right opposite twists at both ends;
and by threading and coupling each of the female threads of the connector, which has an outer diameter approximately the same as that of each of the wire rods, to the male thread of each of the wire rods, thereby continuously supplying two or more turns of the wire rod to the heading machine. The main idea is that the winding start end and winding end of two wire rods are butted together via a connector, and when this connector is rotated in one direction, the wire rods on both sides are screwed together by the left and right reverse twisting screws. The ends are pulled together and firmly connected, and the outer diameter of the connector is made to be approximately the same as each wire rod, so it does not get in the way even when fed into the heading machine, allowing continuous operation of the heading machine for long periods of time. This provides an effect that can be easily realized.
