Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bending device and a screw fastening device for a hose fastening band,

The present invention relates to a banding device for a hose fastening band and a screw fastening device for automatically bending a band of the hose fastening band and fastening the screw of the hose fastening band, .

A hose fastening band generally used in various industrial fields is a means for pressing and fixing the outer circumference of a hose connected to a pipe. The hose fastening band includes a housing having a screw connecting groove of a predetermined size to receive a screw, A screw thread formed on the outer circumference and having a screw head formed at one end thereof and connected to the screw connection groove of the housing; a threaded fastening hole formed continuously with the surface of the metal strip; And a band that is engaged with the engagement piece of the housing.

The above-described housing is automatized and manufactured by the technique disclosed in Patent Application No. 2015-0072865 entitled " Hose fastening band automatic assembly system ". One of the background techniques of the present invention resides in a band which is supplied in the form of a circular ring when assembling and producing the hose fastening band.

In more detail, in order to more efficiently manufacture and assemble the hose fastening band, the band is supplied in the shape of a circular ring so that the upper system is used. At this time, the method of manufacturing the band in the form of a circular ring And the bending process is limited to winding the band produced by the press with a specific pipe, and the efficiency, accuracy and promptness of the work are remarkably deteriorated.

Meanwhile, in recent years, there has been developed a technique of making the band into a circular ring shape by bending the band with a banding device. Such a technique provides an efficiency and accuracy in banding work of the band, I have.

However, on the other hand, it is pointed out that the connection with the hose fastening band automatic assembly system is not taken into consideration at all, and thus the hose fastening band can not be automatically assembled.

As another example, Patent Application No. 2014-0058212 entitled " Hose-band assembling device for hose bands " has been developed to enable automatic assembly and production of hose fastening bands. Here, the fastening pieces are manufactured as they are, The band is used as it is and the assembly (assembly of the housing and the band) and the banding in the circular shape are performed simultaneously during the assembly process.

Accordingly, the above-mentioned horseshoe banding assembling apparatus is very complicated in structure and structure due to simultaneous bending operation of the band, and it is pointed out that there is a problem that the accuracy of the operation is very bad and many defects are caused.

In addition, the horseshoe harness assembling apparatus has a problem that the roundness of the band is lowered during the banding operation. The lowering of the roundness is caused by a difference in rigidity between the portion where the threaded fastening hole is formed and the portion where the threaded fastening hole is not formed in the entire band. The banding operation of the upper hose band, .

Another of the background techniques of the present invention is a screw-in apparatus used in the process disclosed in Patent Application No. 2015-0072865 entitled " Hose fastening band automatic assembly system ".

Specifically, a screw-in apparatus used in a screwing process of a conventional hose fastening band assembling system is composed of a fastening mechanism having a hopper for supplying a screw between bending operations and inserting a screw supplied from a hopper into a housing When the hopper is rotated, the screw moves to the discharge port along the spiral path by the centrifugal force, and the moved screw is sequentially supplied to the supply mechanism along the chute. The supply mechanism inserts a screw, which is sequentially supplied along the chute, into the housing in front of the clamping mechanism.

At this time, the fastening mechanism includes a guide block for accommodating the screws supplied one by one from the hopper, one at a time in front of the clamping mechanism, a driver for projecting and rotating the screw housed in the guide block so as to be inserted into the housing, And a screw is accommodated in the guide block, and the screw is projected (advances) by the operation of the clamping cylinder while rotating the screwdriver in the clockwise direction so that the screw is inserted and mounted in the housing .

In the conventional screw-in apparatus having the above-described structure and function, one screw supplied along the chute is rotated by a screwdriver to be screwed into the housing. This makes it difficult to connect the screwdriver with the screw, There is a problem that it is difficult to manufacture the apparatus and the cost is high, and further, there is a problem that the assembling time of the screw The problem that the operation speed of the hose fastening band assembly system is remarkably hindered and the production amount can be reduced has arisen.
