The reason why the winding roller 160 is provided is that it is inconvenient to store or store the cut steel band when the cutting operation work place is narrow when cutting a steel band having a length of 10M or more.

In order to solve the above-mentioned problem, the automatic steel band cutting apparatus 100 according to the present invention includes the winding roller 160 to easily store or store the steel band cut into a long length in a narrow space.

1, a steel band automatic cutting apparatus 100 according to an embodiment of the present invention further includes a collection box 112 for collecting steel bands cut on the front surface of the base frame 110 And a swash plate 113 is provided on the upper portion of the base frame 110 so that the cut steel band can be accurately mounted on the collection box 112.

The steel band B drawn out from the steel band supply part 120 is connected to the upper part of the base frame 110, more specifically, between the steel band supply part 120 and the steel band out part 140, At least one guide bar 114 and a guide roller 115 are provided for accurately pulling the tape into the band pull-

As shown in FIG. 1, the guide bar 114 includes two pairs of rotation bars 114 which are spaced at the same interval as the width of the steel band B and are rotatable. do.

Meanwhile, the guide roller 115 is provided between the two pairs of guide bars 114, and the steel band B drawn out through the guide bar 114 and the guide roller 115 is separated from the steel band B And is accurately guided toward the lead portion 140.

Meanwhile, the automatic cutting apparatus 100 for a steel band according to an embodiment of the present invention controls the cutting unit 130 and the steel band take-out unit 140 in order to cut the steel band B according to the selected length and number And a control unit 150 for controlling the apparatus.

More specifically, the controller 150 performs the following functions.

First, the main power of the automatic steel band cutting apparatus 100 can be turned on / off via the controller 150, and the cut length and the cut number of the steel band B are input.

When the operation of the automatic steel band cutting apparatus 100 is started after the cutting length and the number of cuts of the steel band B are input as described above, the steel band supply unit 120 The rolled steel band B is pulled out to the lower portion of the cutting portion 130.

More specifically, the steel band B is drawn out by the rotation of the second drive motor 142 of the steel band take-out part 140.

At this time, when the lead-out length of the steel band measured through the lower roller 141b reaches the input cut length, the controller 150 stops the operation of the second drive motor 142.

Thereafter, the first driving motor 131 is rotated to lower the cutting blade 133 connected to the first driving motor 131 and the crank shaft 132 to cut the drawn steel band B by an input length, The cutting blade 133 is moved up again to stop the operation of the first driving motor 131. [

At this time, the motion detection sensor 134 detects the operation of the cutting blade 133 and counts the operation, and stops the cutting operation when the number of cuts is reached.

3, which is a perspective view of an automatic steel band cutting apparatus according to another embodiment of the present invention, a steel band automatic cutting apparatus 200 according to another embodiment of the present invention, unlike the embodiment of the present invention, The protrusions 121, the cover plate 123 and the fixing pins 124 are provided on both sides of the fixing plate 122 so that the two steel bands B can be cut at a time, Are the same as those described in the first embodiment, and will be omitted in the following description.

As a result, the steel band automatic cutting apparatus according to an embodiment of the present invention can automatically cut the steel band used for industrial wrapping to the set length and number by the above-described technical constructions, thereby improving work convenience and efficiency, By automating the cutting of steel bands, there is an excellent effect of preventing labor costs, production cost reduction of products, and safety accidents of workers.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, Various changes and modifications may be made by those skilled in the art.
