Blank loading

Intelligent robotic blank loading

A camera system enables the intelligent loading robot to recognize the position of the blanks of a bulk material quantity on a pallet. The software calculates which blanks form the top layer and which parts the robot can access. The robot then picks up one of the available blanks and feeds it to the MiniBendCenter 2.

Of course, the robot can also grip the blanks in stacks. The blanks do not have to lie exactly on top of each other. And the best thing is that the robot does not need to be taught or programmed. Simply start a bending program and the machine does the rest.

  • No programming or teaching necessary
  • Robot grips the blank and feeds it to the bending center
  • Parts that are upside down are sorted out

Multifunctional vacuum gripper

The multifunctional vacuum gripper allows different blank geometries to be fed without changing suction cups. Each individual suction cup is programmable and can be controlled separately. Two suction cups are fixed and the position of two suction cups can be adjusted.

  • Additional flexibility gain for very different blanks
  • Ideal for unmanned production
  • The arrangement of the suction cups enables a variety of unloading options

Bending sequence

Automatic tool setup

The fast and automatic tool changer places the clamping and bending tools into position. Tools not used for a job are stored in the tool magazine. Due to its rotation axis in the gripper, the tool changer can place a tool in the upper or lower clamping beam as well as in the upper and lower folding beam.

  • Automatic tool change in the shortest possible time
  • Precise took positioning
  • Unmanned shifts due to automatic tool setups

Blank scanner

The blank scanner measures the exact pick-up position of the blank in the hundredths of a millimeter range. The blank will not be aligned a second time during the bending process.

  • Fast bending sequences
  • Outer edges of the blank do not have to be at right angles to each other

Manipulator

In the new generation of the MinibendCenter 2, the manipulator clamps, rotates and positions the bent part using high-precision servo-electric drives. As it can even move between the tools, its design opens up an extremely wide range of applications. 

  • Precise positioning and turning
  • Highest bending precision
  • Constant repeat accuracy
  • Very small parts can be bent

Bending up and down

The folding beams of the MiniBendCenter 2 can bend the sheet metal flanges up and down. The part does not need to be flipped when the bending direction changes. The workpiece always remains horizontal. There is no need to lift the part as with press brake bending.

  • Simple bending sequences and therefore simple programming
  • Fast bending cycles
  • Low unit costs

Unloading and stacking bent parts

Intelligent robotic unloading

The intelligent robot not only loads the blanks, but also unloads the bent parts. The robot knows the position of the provided pallets and unloads the finished parts there. The robot can set up several stacks next to each other. 

If the bent parts are not sensitive, the robot can also place them unsorted in a bulk container.

  • No programming or teaching required
  • The robot can unload finished parts stacked or unsorted

Short transport belt

The folded parts are discharged on a short conveyor belt. They drop into a container at the end of the belt

  • For small parts that cannot be unloaded by the robot
  • Non-sensitive mass-produced parts can fall into a box
  • Discharge of sample parts

Pallet change

Loading blanks

Blanks on pallets
  • Two sliding compartments for pallets for punched or laser-cut blanks
  • Up to four different parts can be stacked on one pallet
  • Bulk parts in pallet with frame
  • Pallets can be changed during operation

Unloading bent parts

Unsorted output of finished parts in boxes
Finished parts can be output on pallets - stacked or unsorted
  • Two places for pallets for finished parts
  • Pallets can be changed during operation
