Trounce Tricky Transfer Troubles
|
|
A mainstay of manufacturing is the CNC machine. The type of cutting can vary from plasma cutting to laser cutting, milling, routing, and lathes. They provide zero defects and greater accuracy, enhanced personnel safety, and eliminate unnecessary waste. CNC machines easily cut materials such as wood, metal, cardboard, stone, plastic, and even fabric.
Our application this month involves clothing material – specifically, using CNC technology to pre-cut fabric before it’s shipped to a T-shirt manufacturer. The product being handled – a 45” x 45” x 12” corrugated tray, weighing a maximum 500 pounds.
Working jointly with our system integrator, Alba streamlined the end user’s manufacturing process. Rooted in the clothing apparel industry, the end user has fifty (50) cutting tables that are 4’ wide and 130’ long.

An overhead machine moves back and forth and layers fabric on the table up to 40” high. The fabric then goes into an automated CNC cutting machine which cuts out T-shirt patterns. After cutting, the material is bundled and placed into corrugated trays.
The trays of fabric are placed on an Alba manufactured cart with gravity roller conveyor mounted on top. The operator then pushes the cart to the main conveying line where it’s conveyed onto a Through-Drive Side Transfer (TDST). The tray is conveyed on the main trunk line to an automatic stretch wrapper. The stretch wrapped trays are then moved to the warehouse for shipment to a T-shirt manufacturer.
Primary Challenges |
| • |
Moving the 500-pound trays: getting the product from 50 cutting tables to the conveyor line quickly and safely. With our system integrator, Alba manufactured a cart with gravity roller to move the totes to the conveyor line. |
| • |
Loading the trays given the number of tables, the system required multiple entry points to get the totes onto the main trunk line. Alba supplied several TDSTs to allow the operators to load in multiple areas located close to their fabric tables. |
Working in tandem with our system integrator, Alba’s conveying system created excellent product flow from the cutting tables to the stretch wrapper. The use of Through-Drive Side Transfers (TDSTs), Motorized Zero Pressure Accumulation (MZPA) conveyors, Turntables, and Chain Driven Live Roller (CDLR) conveyor delivered product to the stretch wrapper easily and efficiently. As a result, the customer now has a conveying system that streamlines their manufacturing process, increasing safety, efficiency, and throughput.
