Custom Designed Machine for Manufacturing Bowling Balls.

Our client manufactures custom made machines for different industries, this time he had a request to build a machine to make Sash Windows faster therefore reducing production costs.

 

The client wanted to speed up the assembly of Sash windows and to be able to assemble up to a 100 windows per hour. Using a 3 axis TRM motion controller with MAP software, 3 servomotors of 1.2 Nm each with 1000 ppr encoder, a TRM electrical cabinet, pre-made cables between the electrical cabinet and controller, 3 proximity sensors for home position and 2 beam sensors to detect the edge and size of each window we were able to build a machine that exceeded the job requirements. The machine can now assemble 120 sash windows per hour which is 4 times faster than without the machine when the production was 30 sash windows per hour.

 AUT 8801

The great advantage of this machine is its automatic window size detection and automatic setup to assembly the different window sizes which avoids the manual setup of the machine.

Today the user is manufacturing sash windows with better quality than ever and still remains competitive with labour costs down and increased production.

On the left, the Motion Controller operates the conveyor motor to feed the sash windows and using beam sensors (right hand picture) to detect the edge and size of the window. The controller will stop the conveyor in the required position, then will operate the servomotors to compress the window at the desired pressure. After the window is compressed, the controller will activate the outputs to fire the nails at 45 degrees.

SOFTWARE

The controller was programmed using the Motion Application Programme ‘MAP’. ‘MAP’ has been used in a vast variety of machines and applications giving the user a greater control of costs, saving money and time on software development.


One of the great advantages of MAP is that it allows end users to create their own programs with no need for a skilled programmer. MAP has been used in different applications from Sash Windows Machines, Bowling Ball Machines, Tube Bending Machines, XYZ tables, Pallet Manufacturing Robots, rotary axes and milling machines to pharmaceutical mixers among other applications.

MOTION

Point to Point move:
Moves a single axis from point to point with no acceleration, or velocity parameters. This command is mainly used by the profile generator or for holding  position.


Trapezoidal move:
Moves a single axis from point to point, using programmed acceleration and velocity parameters. If the velocity can not be reached the function will generate a triangular profile.


Linear Interpolation:
This function allows up to 4 axis to be linked together to produce a linear profile. Full use is made of the acceleration and velocity parameters.


Circular Interpolation
This function allows two axis to be linked together to produce a circular profile. Full use is made of the acceleration and velocity parameters.
