Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wire rod storage device in a processing line.
[0002]
[Prior art]
In general, a processing line as shown in FIG. 3 is often used in an electric wire manufacturing factory. In other words, the raw material wire is sent out from the delivery bobbin, or it is manufactured and sent out from the base material as in the case of optical fiber, the raw material wire is subjected to some processing, and the product wire is taken up while being taken up by the take-up device. It is wound around a bobbin.
[0003]
In this case, for example, when replacing the winding bobbin, it is often impossible to stop the manufacturing process of the wire at the beginning. In this case, during the bobbin replacement, the product wire is temporarily stored there by a storage device, and the winding bobbin After completion of the exchange, the take-up speed is temporarily increased to cancel and wind up the wire material stored in the storage device.
[0004]
As a conventional storage device for this purpose, although not shown in the drawing, a wire rod is wound around a large number of opposingly arranged pulleys, and the distance between the pulleys is gradually increased to increase the amount of the storage wire rod. The device is well known.
[0005]
[Problems to be solved by the invention]
However, in the case of such a conventional storage device, there is a drawback that it is very troublesome to wire a large number of pulleys at the time of initial work preparation, and this wire drawing process has a disadvantage that it is difficult to automate. .
[0006]
[Means for Solving the Problems]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. The solution according to the invention of claim 1 is a cylindrical shape having a winding wire-like winding groove on the outer periphery thereof, the central axis of which is formed. A storage drum that is driven to rotate around the outer periphery of the storage drum, an outer peripheral roller that is rotatably connected at an appropriate interval along the bottom surface of the first winding groove of the storage drum, and extends parallel to the axis of the storage drum A guide rod, a bracket having a groove engaging element slidably engaged with the guide rod and engaged and guided in the winding groove, and a bracket rotatably supported by the bracket and provided at a position facing the winding groove And a winding device comprising a moving roller, wherein the moving roller is initially set at a position facing the second winding groove.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. Reference numeral 2 denotes a cylindrical storage drum which is supported and fixed so as to be able to rotate around its central axis, and is rotated by a drive motor 6 capable of reversing forward and reverse via an appropriate transmission element such as a pulley. .
[0008]
A helical winding groove 21 is formed on the outer periphery of the storage drum 2. However, a plurality of outer peripheral rollers 3 are rotatably provided at appropriate intervals along the bottom surface of the winding groove 21 on the first periphery. The outer peripheral roller 3 is guided by the outer peripheral roller 3 so that the wire 1 can travel, and frictional sliding when the wire 1 is in direct contact with the bottom surface of the winding groove 21 can be avoided.
[0009]
Next, the winding device 5 will be described. This comprises a guide rod 53 installed so as to extend in a position close to the outer peripheral portion thereof in parallel with the central axis of the storage drum 2 and a bracket 50 that slides while being guided by the guide rod 53. The bracket 50 includes a groove engaging element 52. The movable roller 51 is rotatably supported.
[0010]
The moving roller 51 has a rotation axis parallel to that of the storage drum 2 and is disposed at a position facing the second winding groove 21 in a preparation stage for starting operation. In addition, the groove engaging element 52 is designed so that the tip of the groove engaging element 52 has a spherical shape, for example, and can slide in the winding groove 21 without resistance. What is important is that the distance between the groove engaging element 52 and the moving roller 51 along the guide rod 53 is set equal to the pitch distance of the winding groove 21.
[0011]
Next, the line and operation of the inventive device will be described. The wire rod 1 is guided from the upstream device to the moving roller 51 through the introduction guide roller 4 provided at an appropriate position, and then is wound around the first winding groove 21 and then directed toward the downstream device. .
[0012]
At all times when the storage device does not act, the wire 1 is guided to the downstream device by being guided by the rotation of the plurality of outer peripheral rollers 3 in the first winding groove through the introduction guide roller 4 and the moving roller 51. Due to the presence of the outer peripheral roller 3, an inconvenient situation where the wire 1 is rubbed against the bottom surface of the winding groove 21 does not occur.
[0013]
When the line take-up device stops, the drive motor 6 starts rotating. The storage drum 2 is rotated counterclockwise in FIG. Since the moving roller 51 first faces the second winding groove 21, it starts winding the wire 1 around it.
[0014]
With the rotation of the storage drum 2, the groove engaging element 52 was initially engaged with the third winding groove, but gradually moved to the fourth and subsequent winding grooves, and the moving roller 51 was also moved accordingly. Thus, the winding and storage of the wire proceeds.
[0015]
When the take-up device restarts, the storage drum 2 is rotated in the reverse direction to discharge the stored amount of the wire 1. It is sufficient to continue until the moving roller 51 returns to the storage start position shown in FIG.
[0016]
【The invention's effect】
According to the first aspect of the present invention, as described above, there are advantages such as the fact that the line drawing is extremely simple and easy, the configuration of the apparatus itself is simple, and the stored dose is relatively large.
