The feeder 110 is loaded with the pre-machining plate 300 to be fed into the press working member 200 from the upper surface of the movable table. Here, the feeder 110 is provided with movable rollers, and the plate member 300 mounted on the upper surface thereof is supported by a supporting means (not shown) to prevent disturbance of the stacking state during movement or external impact .
The load transfer unit 120 includes a transfer arm 121 which is moved in the vertical direction and the back and forth direction to suck the plate material 300 loaded in the supply unit 110 by vacuum or magnetic force, 1 mold 211 as shown in Fig. The load transfer unit 120 senses the thickness of the plate material 300 or the load of the plate material 300 absorbed by vacuum or magnetic force by the transfer arm 121 and transmits a detection signal to the control unit 160. [
2 and 3, the inversion transfer unit 130 is constituted by a robot arm 131 having the same number as the process number (the number of molds) processed in the press processing member 200, and the molds 211 to 21N (300 ') < / RTI > That is, the first robot arm 131 transfers the plate material 300 'processed in the first mold 211 to the second mold 212, and the second robot arm 131 transfers the plate material 300' The third mold 213 and the third robot arm 131 move from the third mold 213 to the fourth mold 214. The sixth robot arm 131 moves the finished work sheet 300 '' from the sixth mold 216 to the discharge transfer section 140.
The at least one robot arm 131 further includes a conveying means 132 and a support table 133 for supporting the conveying means 132 and the robot arm 131 so as to be movable in the front, rear, left and right directions.
The conveying means 132 is moved in the front, rear, left, right, and up and down directions so as to simultaneously convey the one or more robots described above in the same direction.
The robot arm 131 is provided with a rotatable head portion 131a for reversing the movement of the plate member 300 'between the respective molds of the press working member 200 as described above. It is preferable that the head 131a is provided with multiple shafts so that the vacuum adsorber or the magnet is provided to attract the plate material 300 and rotate 180 degrees.
The discharge transfer unit 140 transfers the processed sheet material 300 "completed in the final process of the press processing member 200 transferred by the reversal transfer unit 130 to the discharge stacking unit 150. For this purpose, the discharge conveying unit 140 preferably includes a discharge arm 141 which is movable in the front and rear direction and / or the left and right direction and capable of sucking the plate material 300. The discharge arm 141 may be provided with, for example, a head 131a provided with a magnet or a vacuum adsorber.
The discharge stacking part 150 supports the processed sheet material 300 '' conveyed by the discharge conveying part 140. To this end, the discharge stacker 150 may be a table movable by a roller, and may further include a support means for preventing shaking of the work sheet 300 on the upper surface.
The control unit 160 drives the load transfer unit 120 or the discharge transfer unit 140 when an operation command is given from the operation panel. In particular, the control unit 160 issues an alarm signal if the quantity of the plate material 300 detected by the load transfer unit 120 is larger than the set quantity. For this, the controller 160 may further include a buzzer 161 and a light emission lamp 162.
The present invention includes the above-described configuration, and an operation achieved through the above-described configuration will be described below.
First, the worker places the feed stack 110 on which the pre-machining plate 300 is placed on the feed side of the press working member 200. When the operator turns on the operation switch 163 formed on the control unit 160, the control unit 160 outputs a drive command to the load transfer unit 120 to the discharge stacker 150.
Thus, the load transfer unit 120 moves the pre-machining plate material 300 loaded on the supply stacking unit 110 to the first mold 211 of the press processing member 200. At this time, the load transfer unit 120 senses the quantity of the plate material 300 picked up by the transfer arm 121 and transmits a detection signal to the controller 160. [
The control unit 160 receives the detection signal of the load transfer unit 120 to check whether there is an abnormality. If an abnormality is detected, the buzzer 161 or the light emission lamp 162 is driven to issue an alarm.
The inversion transfer unit 130 moves the plate material 300 completed in each step connected to the first to Nth molds 211 to 21N to the adjacent mold under the control of the control unit 160. [ At this time, the press processing member 200 proceeds the process of each mold by the control of the controller 160, and transmits a completion signal to the control unit 160 when the process is completed.
The control unit 160 controls the inversion transfer unit 130 to move the completed plate material 300 'to the adjacent molds when the finish signal for each process of the press processing member 200 is received.
At this time, when the process of the last mold, for example, the sixth mold 215, is completed, the sixth robot arm 131 dedicated to the sixth mold 216 is driven to discharge the completed processed sheet material 300 " To the transfer unit 140.
The discharging transfer unit 140 sequentially stacks the processed sheet material 300 "transferred from the reversal transfer unit 130 on the top surface of the discharging unit 150 under the control of the controller 160.
As described above, according to the present invention, since the plate material 300 is automatically transferred throughout the press working process for performing multiple processes, no manual work is required and the work force can be reduced and the working time can be reduced.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
Further, the terms used throughout the specification of the present invention are used to illustrate an embodiment, and the present invention is not limited thereto. Even if a configuration having another name is used, . ≪ / RTI >
