Description

[0001]
BACKGROUND OF THE INVENTION
In the present invention, when small parts such as electronic parts are continuously produced in large quantities in a hoop state, a work-in-process product or a finished product processed or molded in the hoop state is wound on a bobbin in a hoop state. The present invention relates to a hoop material winding method and a hoop material winding device used therefor.
[0002]
[Prior art]
A conventional hoop material winding device of this type will be described with reference to FIG.
[0003]
In FIG. 7, reference numeral 20 denotes a molding machine for processing or molding an electronic component or a work in progress thereof in a hoop state, and reference numeral 21 denotes a hoop-shaped electronic component molded by the molding machine 20 (hereinafter referred to as a hoop material 1). The hoop material take-up device 21 includes a main body frame 23 on which a bobbin 22 for taking up the hoop material 1 is rotatably mounted, and the main body frame. The drive unit 24 is configured to rotate the bobbin 22 coupled to the bottom surface part 23.
[0004]
The conventional hoop material winding device 21 configured as described above winds the start end portion of the hoop material that is molded by the molding machine 20 and is intermittently carried out around the bobbin 22, and the bobbin 22 is illustrated by the drive unit 24. It was comprised so that winding to the bobbin 22 could be performed by rotating in the direction of the arrow in the middle.
[0005]
[Problems to be solved by the invention]
However, in the conventional hoop material winding device 21, when the hoop material 1 molded by the molding machine 20 is completely wound around the bobbin 22, the drive unit 24 is stopped to stop the rotation of the bobbin 22 and the molding is performed. The bobbin 22 had to be replaced after the operation of the machine 20 was stopped.
[0006]
For this reason, in addition to the time required for replacing the bobbin 22 (4 to 5 minutes), not only the return time (4 to 5 minutes) of the molding machine 20 is required, but also the molding machine 20 that mainly performs the purge operation. There was a problem that a molding loss was caused by the returning operation, and a yield reduction was unavoidable.
[0007]
Such bobbin 22 replacement work is required every 1 to 1.5 hours when about 10,000 electronic parts are wound on one bobbin 22 in a hoop state, which reduces productivity and yield. In addition to being unavoidable, it had a problem that it could not be unmanned for a long time.
[0008]
The present invention solves such conventional problems, enables bobbin replacement without stopping the operation of the molding machine, improves productivity and yield, and realizes unmanned operation for a long time.

This is a method of winding the hoop material in which the hook at the other end is engaged with the start end portion of the hoop material and the hoop material is wound around the bobbin via the guide member after being positioned and held in the clamp portion .
[0010]
And as a winding device of the hoop material used for the winding method of the hoop material, a winding unit and a fixed base that is upstream of the winding unit and is detachably connected to the winding unit. And the winding part has a bobbin for winding the hoop material, a motor arranged for rotationally driving the bobbin, and a clamp part for holding an engaging part provided on the guide member for winding.
