The following describes the operation of the insert plate feeder of the present invention injection case of the mobile communication terminal having the configuration as described above.

First, an operation of sequentially taking out the insert iron plate M1 loaded on the cassette 110 'placed in the linear take-out position P1 will be described.

Insert iron plate M1 is loaded in all four cassettes 110 and loaded, insert iron plate take-out jig (not shown) is inserted into the cassette 110 'installed in the linear take-out position P1 When the uppermost insert iron plate M1 at the vertical ejection position H1 is taken out from the M1, the insert iron plate detecting sensor 161 detects that the insert iron plate M1 is missing at the uppermost level and inserts the uppermost insert iron plate into the control box (M1). The detection signal outputting M1) is output.

The control box receiving the detection signal from the insert plate detection sensor 161 controls the driving of the rotary motor 131 so that the lifting screw 132 rotates.

When the elevating screw 132 is rotated by the driving of the rotating motor 131, the elevating plate 133 is raised, and the insert iron plate pusher 120 is placed in the linear ejection position P1 as the elevating plate 133 is raised. The insert iron plate M1 loaded on the cassette 110 'is pushed upward so that the insert iron plate M1 is again positioned at the vertical ejection position H1.

When the above operation is repeated to take out all of the insert iron plate M1 loaded on the cassette 110 'placed at the linear take-out position P1, the lifting plate 133 reaches the upper limit point H2. The sensor 162 detects this and outputs a takeout completion signal to the control box.

The control box receiving the take-out completion signal drives the rotary motor 131 to lower the lifting screw 132.

When the lifting screw 132 reaches the lower limit point H3, the lower limit detection sensor 163 is detected and the detected signal is sent to the control box. The control box stops the rotation motor 131 based on this.

Next, the process of transferring the cassette at the linear standby position to the linear take-out position by linearly moving the linear motion plate 140 by the set distance after completing the above operation will be described.

When the rotation of the rotary motor 131 is stopped, the control box drives the servo motor 151 to linearly move in the direction of the arrow shown in FIG. 1 by the set distance of the linear motion plate 140.

In the present embodiment, four cassettes 110 are placed in the linear motion plate 140 at equal intervals.

The linear moving plate 140 moves linearly by a set distance so that the cassette 110 ″ placed at the horizontal stand-by position P2 closest to the linear take-out position P1 is placed at the linear take-out position P1. Linear transfer to the position of the cassette 110 ', and the above operation of taking out the insert iron plate (M1) is repeated.

Now, after taking out the insert iron plate M1, the cassette 110 'is linearly conveyed by linearly moving the linear motion plate 140 by a set distance by the drive control of the servomotor 151 as described above. Then, the operation of linearly transferring the cassette 110 ″ waiting at the horizontal standby position P2 to the linear take-out position P1 with the insert iron plate M1 inserted therein is repeated.

In one embodiment of the present invention has been described taking an example that four cassettes 110 are placed in the linear motion plate 140. If the number is placed in the linear motion plate 140 is not limited to this, the number is not limited, and for example, five or six will be possible.

Increasing the number of cassettes 110 mounted on the linear motion plate 140 will have the advantage that the replacement cycle of the entire cassette becomes longer.

In addition, in one embodiment of the present invention, one insert 110 can be inserted into the insert iron plate (M1) at the same time in two rows, by an upward lift by a pair of insert iron plate push rod 120 as an example Explained. The present invention is not limited thereto, and the number of rows of the insert iron plate M1 inserted into one cassette 110 is, of course, within the technical scope of the present invention.

The above embodiments of the present invention are merely one embodiment of the technical idea of the present invention, and of course, other modifications are possible within the technical idea of the present invention.
