First, when the bus bar B which is in the state before the punching, marking, cutting, bending, etc. is processed is placed on the feed roller 110 of the feeding unit F / U, the bus bar B is the feed roller 110. ) To the loading unit (L / U).

At this time, the bus bar (B) is a plate having a predetermined width and length is moved to the centering state by the guide action of the guide rollers 120 respectively installed on the left and right sides of the front and rear of the moving path during the movement process.

When the bus bar B reaches the inlet side of the loading unit L / U, the optical sensor 232 detects the entry of the bus bar B, and the feeding roller 220 according to the detection signal When rotated, the bus bar B moves forward by the action of the feeding roller 220.

Then, the input distance of the bus bar B is detected by the input distance detecting means so that the input distance of the bus bar B can be controlled for processing. When the detected input distance matches the set value, the bus bar Transfer of (B) is stopped and punching processing is performed.

Punching by operation of the punching machine 240 is as follows.

First, the frame 242 equipped with the punches 241 is punched in the standby position by the transfer action of the ball screw device 243 according to the driving and control of the servomotor (not shown) constituting the punching machine 240. It will move to the initial position for.

In addition, the hole punch 241 mounted thereto is moved to an initial position for punching by the movement of the frame 242. The punching machine 240 includes a detection means for detecting whether the initial position has been reached. It is provided to detect this.

On the other hand, after the initial position control for punching is completed as described above, the punch 241 is lowered to process the hole on the surface of the bus bar (B).

After the hole processing in the punching unit (P / U) is completed, the bus bar (B) is transferred to the marking unit (M / U) for marking, which is the next process, the marking position of the bus bar (B) The movement distance control of the furnace is performed by the rotation control of the feeding roller 220 constituting the loading unit (L / U).

The bus bar B enters and stops at a predetermined position of the marking unit M / U by the rotation control of the feeding roller 220, and the marking machine 300 for automatically marking the input mark in this state is operated. To mark a desired mark (eg, DH) on the busbar (B) surface.

Then, after marking in the marking unit (M / U), the bus bar (B) is sent to the cutting unit (C / U) for cutting to a predetermined length, the bus bar (B) is moved to the cutting position Distance control is also achieved by the rotation control of the feed roller 220 located in the punching unit (P / U).

That is, when the bus bar B moves by a certain distance by the rotation control of the feeding roller 220 and stops at a predetermined cutting position, the upper cutter 410 is lowered, and thus the upper cutter 410 and the lower cutter. The busbar B is cut by the intersection of 420.

After the cutting process is completed, the bus bar (B) is completely out of the biting state of the feeding roller 220 as the feeding roller 220 continues to rotate for a predetermined time, thereby climbing on the transfer roller 690 of the transfer unit Will move a certain distance. That is, when the entry of the busbar B into the transfer unit is confirmed by the optical sensor 710 installed on the entry side of the transfer unit, the feed roller 690 rotates and the busbar B enters the transfer unit completely. After that, a separate optical sensor 720 detects this and stops the driving of the feed roller 690.

On the other hand, the bus bar (B) unloaded after cutting is selectively processed depending on whether or not bending is required, and is conveyed in different directions by the transfer unit depending on whether bending is required.

For example, when the tilting plate 610 is rotated to the left, it is sent to the bending unit (B / U) to be bent, and when it is rotated to the right, it is a finished product without the bending process, so that the predetermined position of the workpiece storage unit (S / U) It is loaded in.

In the above, whether or not the bending process for the bus bar B is necessary may be determined according to a program previously input to a controller (not shown).

On the other hand, the bus bar (B) sent to the bending unit (B / U) by the treatment of the sorting transfer unit (T / U) is the lower mold 510 and the upper mold 520 of the bending unit (B / U). The bus bar (B) is positioned at a predetermined position therebetween, and the bus bar (B) is upper mold 520 as the upper mold 520 of the end shape to be joined to the V-shaped lower groove 520a is lowered by the operation of a hydraulic apparatus installed separately. ) And the lower mold 510 is bent at a predetermined angle.

After the bending of the bus bar B is completed as described above, when the upper mold 520 is raised to remove the interference between the upper mold 520 and the lower mold 510, the bus bar B is clamped 800 or It is handled by the robot arm and placed on a predetermined loading space separately provided on the workpiece loading unit S / U.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.

For example, the optical sensor and the proximity sensor presented as the detection device in the above embodiment can be replaced with other sensors that achieve the same purpose, as well as punching, cutting, marking, bending, etc. in the bus bar (B) processing unit. Each unit may be changed in arrangement as necessary, and may be omitted as necessary.

In addition, the angle of the V-shaped lower mold 510 and the upper mold 520 constituting the bending unit (B / U) may also be provided in a variety of forms depending on the desired bending angle is also natural, the bus bar bending Of course, the mold for the right and left (ie, left and right molds) may be arranged, of course.

The present invention is to allow a series of machining operations such as punching, cutting, bending, marking to be performed on the bus bar (B) applied to various distribution systems and distribution panels, such that it can be automatically performed continuously in one transfer line, The productivity and work efficiency of the busbar (B) machining operation can be significantly improved, and the safety can be improved through automation, so the industrial application is very high.
