Custom Trim Chopping Machine

A producer of Acrylic sheet saw the Rotary Scrap Cutter that we offer to the vinyl siding industry on our web site and called us to see if it could be used to chop up the scrap material that they cut off the edges of the Acrylic sheet stock that they produce. Unfortunately, the standard machine was not suitable, so we decided to design and build a custom machine for the application. The edge trimmings can range in thickness anywhere from 1/16" up to 1/2" and be anywhere from one to fifteen inches wide. The thinner the sheet the faster it runs. Their operators struggled to keep up when they had to handle the edge trimmings by hand and because of the wide variety of lengths they had trouble storing the scrap. They also had difficulty maximizing the containers that they use to ship the scrap out to a recycler. By developing a pair of chopping machines, one for each side of the line, they could collect all the scrap in Gaylord bins that stack up and fill the containers perfectly and the operators are able to focus all their energy on the good product.

Highlights of the Trim Chopping Machine Manufacturing Project

Product Description
A machine assembly consisting of two choppers, product conveyors and a scrap conveyor.

Capabilities Applied/Processes
Primary:
We designed the new machine in 3D Cad and then produced our own set of prints for our internal manufacturing needs, some of which were then processed with CAM software to develop CNC programs used to run the parts.

Equipment Used to Manufacture Part
We used manual and CNC mills, lathes and Wire EDM's to make all the parts. We also had weldments that were welded in house.

Benefits
Made the operators job easier and allowed them to focus more on inspection of the materials.
Chopping the edge trimmings into small pieces maximized what could be put in a shipping container for recycling.

Operation
The choppers are hydraulically operated scissor like mechanisms that cut progressively from the outside edges in. Part of the design included blade inserts that can be sharpened by grinding and reinstalled without having to make any machine adjustments. The chopper assemblies are mounted on rails so they can be positioned as needed to work with a wide range of sheet widths. The chip conveyor is a conventional metal working chip conveyor.
